I’m sitting on a step to the back door of my friend’s house beside a barbecue at about 8:00pm. As I looked at the full bowl in my pipe, I knew that there was more than I should be smoking at once. It was more than I gave to the previous tripper and he didn’t even finish it; two people got high off of the last so-called hit.  That’s a lot more than I thought.” I was told many times by my friends that the hit should be held in for a long time or it won’t work, but it was a huge hit and I exhaled almost right away. I put the pipe down on the barbecue shelf as everyone bitched about exhaling too soon, but I soon realized that holding the hit in was not needed.
It’s hard to remember the first feelings. It was as if my vision was distorted, but I still could not pinpoint any difference in anything I looked at…. for a while. Some of my muscles also felt very heavy(a cool feeling that you get even on small doses, one of the only effects after taking a small hit other than some cool vision changes similar to those of mushrooms). The heavy feeling is followed by a stage that makes the user feel as his or her body is being stretched and smeared around.
This is where it gets hard to remember(I still don’t remember a lot of what happened in the physical world; it took a lot of work and talking to the people who were there to piece everything together afterwards) but I will explain it as well as I can. At this point, according to my friends, was when I tried to get up. There was still some salvia on my scale tray sitting on the barbecue’s shelf next to me. Apparently I wasn’t able to support myself and put my hand on the tray and salvia as I got up, but my friends managed to save it and get my hands away from it. I believe this is when I started leaning on the top of the barbecue.
My elbows were on the surface with my hands supporting my head. I do remember being in this position for a little bit and I think I was there for most of the trip but this is still unclear. I then started to go into a different world. While I was leaning on the barbecue, I remember wondering why I couldn’t stand, and my goal was to figure out how to stand up(we discovered that most people had important goals during their trips, which are focused on intensely, that they want to accomplish). My goal was to stand up. I will discuss these goals in more detail later.
While leaning on this barbecue, I felt as if my body was turned horizontally and I lost touch with the ground(the ground disappeared and I paid no attention to where my body was), but I was very low to the ground(or where it would have been if it was there). I remember being above the barbecue and then feeling myself move down to about knee-level and seeing, up close, the side of the barbecue from that level, but according to some people I was leaning on the top of the barbecue the whole time. At that point, my body felt as though it was twisting up, in an uncomfortable but painless way. I was still thinking of how I was going to stand up, but it was getting harder because my body was twisting around the barbecue in ways that my joints would never be able to bend(remember, I’m still lying horizontally in the air).
All of a sudden, all the colours of the barbecue, the wall behind it, and everything else in sight twisted together in one big swirl. That was when I lost touch with my body, which was strange because I was still focused on my goal of standing up. This is when it got really scary. I was in another dimension of many colours that cannot be described. In some trips, salvia erases reality and then rebuilds a new reality that I believe is real, even though it’s nowhere close to real.  I literally did not even know there was another world; I was in the only world I knew. Sometimes my eyes would see the barbecue or the wall behind it, but my mind would not process it. My mind felt like it was touching the whole universe and what my eyes saw did not matter.
The following is the strangest part. As I was in this colourful dimension, I was still thinking about my goal of standing up, even though I was unaware that I even had a physical body. I might as well just say that the physical world and my body never existed, because in my mind, they didn’t. So I’m in this world of moving colours, hoping to stand up even though there is no physical world at all and I only know of this new, strange universe, and nothing else.
This is the peak of the high, and the part that made it a scary trip. During the time of the new dimension, I felt that I had a master that had complete control over me(do not ask what this master was because it cannot be explained). It was like this higher being was disallowing me to stand up and I remember thinking, “Why can’t I stand? Why won’t you let me stand up?” I was constantly begging and pleading for permission to stand up with a body that didn’t exist. I felt helpless and I did not know what else I could do because this higher being did not give me permission to stand. It felt like I would be stuck there forever, since I had no knowledge of reality.
Soon after, I started to regain consciousness, but that does not mean that things were making sense again. The entrance to reality was just like the exit. All the colours unswirled to become the backyard of my friend’s house, but when I was able to make sense of what I saw, I was sitting back on the step. I later found out that my friends were worried and sat me back down, but I do not remember when. So I find myself looking down at everyone’s feet, but as I was looking at everything, I still didn’t know what anything was. After a while, I eventually saw that I was looking at everyone’s feet and thought to myself, “Whoa, I’ve been looking at them for so long and I didn’t know what/who they were.”  I actually assumed that I was previously stumbling all over the place, when I really wasn’t.
Then I got to that stage where I thought I was normal enough to associate with others.  I’m not sure if this happened before or after I left reality, but I remember trying to talk. I was trying to state how high I was. Every time I tried to get a sentence out, the first word or two made it out, but my voice would cut off and wouldn’t work. I eventually gave up and buried my face in my sleeve to signal to everyone else that I was unable to speak. This was the only logical solution I could think of at the time. It was disappointing, because I was dying to share with everyone what I had just experienced.
After a couple seconds, I was able to speak, and for some reason, my friend’s music from his headphones really got to me. It didn’t make me angry, but for some reason(well, not really), I felt that it had to be turned off.
“Dude, turn that off.”
“Uhhh, what?”
“Do it. Turn that music off now.”
“Uhh, ok. How about I just change the song?”
“No, it has to be off…. Actually, whatever… Doesn’t matter. Change it.”
This was confusing because it cannot be explained for at all.  He didn’t want to hear the guy talk(who was also a bit high at the time) and it was important to him that he got the guy to be quiet. He felt pretty bad about that afterwards because it was so random. This is the ‘special goal’ that I’m talking about.
Things came back to normal quickly after this. I remember people telling me that I was out for about five to ten minutes, but it felt like less than a minute. Apparently, I looked like I was going to fall over and black out. I guess that new world was a black out, but I didn’t fall over. Afterwards, there was a strange physical burnout and, in this stage. This stage only lastED a few minutes to leave the me completely sober, awake, and aware, but, also, very relaxed as well.
This was written to the best of my knowledge, and it took a lot of time afterwards to figure out what happened. I even forgot about most of my trip until it slowly started to piece itself together in my memory. A lot of my time was spent that night talking to my friends about what was happening during the trip, which is the key, for me, to remembering the forgotten parts.
The Goal
As for this ‘special goal’, none of us had ever heard about it before and we only learned about it from our own experience. I feel that it is because my mind becomes focused on one thing, and if that thing is a goal that can be accomplished or knowledge I seek, I will not give up until this happens or until I'm back in reality. The best example of this special goal is a friend’s trip later that night. There were four of us in the room.
She got herself worked up about a secret that she thought we were holding from her.  After making herself believe that we were holding a secret from her, she started to get pissed off. This is a person that most people have never seen angry before and she never raises her voice - the calmest person I’ve ever met. She started yelling violently and swearing at us, asking us to “tell her” but we could not figure out how to respond. We actually thought that she would become violent.
She even described a series of events that happened in her mind that related to this secret(like my mental world involved my goal of standing up, a goal from the physical world). It involved an army or a group like an army marching nonstop with one leader telling her to come march with them. She thought that they too were holding this secret from her and she said that she was skeptical of the people in her vision for that reason. She did not give up on figuring out what this secret was until she became happy and she laughed a lot for a short period of time; strangely, she became sober in an instant rather than after a slow transition. There is much about her trip that I will not describe because I only want to show this idea of the ‘special goal’. I have never seen any source of information mention this special goal, so this matter requires more investigation.

Creating a BSON Document¶
The bson_t structure¶
BSON documents are created using the bson_t structure. This structure encapsulates the necessary logic for encoding using the BSON Specification. At the core, bson_t is a buffer manager and set of encoding routines.
Tip
BSON documents can live on the stack or the heap based on the performance needs or preference of the consumer.
Let’s start by creating a new BSON document on the stack. Whenever using libbson, make sure you #include <bson/bson.h>
.
bson_t b;
bson_init (&b);
This creates an empty document. In JSON, this would be the same as {}
.
We can now proceed to adding items to the BSON document. A variety of functions prefixed with bson_append_
can be used based on the type of field you want to append. Let’s append a UTF-8 encoded string.
bson_append_utf8 (&b, "key", -1, "value", -1);
Notice the two -1
parameters. The first indicates that the length of key
in bytes should be determined with strlen()
. Alternatively, we could have passed the number 3
. The same goes for the second -1
, but for value
.
Libbson provides macros to make this less tedious when using string literals. The following two appends are identical.
bson_append_utf8 (&b, "key", -1, "value", -1);
BSON_APPEND_UTF8 (&b, "key", "value");
Now let’s take a look at an example that adds a few different field types to a BSON document.
bson_t b = BSON_INITIALIZER;
BSON_APPEND_INT32 (&b, "a", 1);
BSON_APPEND_UTF8 (&b, "hello", "world");
BSON_APPEND_BOOL (&b, "bool", true);
Notice that we omitted the call to bson_init(). By specifying BSON_INITIALIZER
we can remove the need to initialize the structure to a base state.
Sub-Documents and Sub-Arrays¶
To simplify the creation of sub-documents and arrays, bson_append_document_begin() and bson_append_array_begin() exist. These can be used to build a sub-document using the parent documents memory region as the destination buffer.
bson_t parent;
bson_t child;
char *str;
bson_init (&parent);
bson_append_document_begin (&parent, "foo", 3, &child);
bson_append_int32 (&child, "baz", 3, 1);
bson_append_document_end (&parent, &child);
str = bson_as_canonical_extended_json (&parent, NULL);
printf ("%s\n", str);
bson_free (str);
bson_destroy (&parent);
{ "foo" : { "baz" : 1 } }
Simplified BSON C Object Notation¶
Creating BSON documents by hand can be tedious and time consuming. BCON, or BSON C Object Notation, was added to allow for the creation of BSON documents in a format that looks closer to the destination format.
The following example shows the use of BCON. Notice that values for fields are wrapped in the BCON_*
macros. These are required for the variadic processor to determine the parameter type.
bson_t *doc;
doc = BCON_NEW ("foo",
"{",
"int",
BCON_INT32 (1),
"array",
"[",
BCON_INT32 (100),
"{",
"sub",
BCON_UTF8 ("value"),
"}",
"]",
"}");
Creates the following document
{ "foo" : { "int" : 1, "array" : [ 100, { "sub" : "value" } ] } }

https://angular.io/docs/ts/latest/guide/cheatsheet.html
Odd 'gotcha' behaviors:
- Every component ts file needs a template so if you delete the html reconfigure the ts file to say "template: ``"
Installation:
- npm install typescript -g (tsc -v)
- apm install atom-typescript
- npm install -g angular-cli
Commands:
- ng new project-name (creates a project)
- ng new project-name --prefix ab (creates a project but prefixes templates with 'ab' or anything else you choose)
Create/Add Component Workflow (Be in app folder or deeper):
- ng g c componentname --flat (--flat (optional) flag will disallow this component from being inside its own folder)
- In app.component.ts add:
- import { ComponentnameComponent } from './componentname.component';
- In your template (.html) file add component selector tags found in componentname.component.ts
Create a Class:
- ng g cl classname
- import { Classname } from '../classname'; (Import this wherever it is needed; from 'whichever directory it's in')
Data passage example (Recipe-list, recipe-detail, recipe):
- Overview: The recipe-list has a recipe that we want to display on recipe-detail. recipe-detail will be displayed on recipe.
- Recipe constructed in the recipe-list component
- Displayed on recipe.html, gives information through output emitter (Property binding, emits with click event)
- Recipe information called in recipe-detail component (@Input() takes any information emitted)
- Also displayed on recipe.html so it has access to the information emitted
- Formats information on its frontend, which is displayed on recipes template
- Recipe constructed displayed on recipes template (which is displayed on the app template)
Create a Directive:
- ng g directive directivename
Directives:
- Instructions: Tells Angular 2 what to do ; Components
- {{ item }} (Tells Angular 2 to Loop)
- (Tells Angular 2 to render a component to a page)
- Attribute Directives: Interact with Element applied to
- ngClass ([ngClass] brackets are used for property binding)
- Structural Directives: Interact with DOM
- *ngIf
Debug:
- Chrome Debugger, sourcemaps, Augury
Services:
- Provide, Store, Interact with Data (eg interact with a DB on a server)
- Provide communications for components and classes
- Access to business logic from various locations within your app (DRY)
B. Dependency Injection:
- Giving an instance of a service to components, directives, classes, etc.
- eg. constructor(argument: Service) {} ...and in the component (or a higher level) -> provide: [Service]
- Step by step injection:
- Create service to be injected
- Import it to component where it's to be injected and add it to a constructor with a private variable of type ServiceName
- Import and provide to appmodule.ts providers (the parent component)
- All linked up, now do stuff with it


In this step, we want to generate a map to play on.
A map is often stored as a 2D array, which is nothing more than an array where every element is another array. Specifically, our map will be an array of columns and each column will be an array of tiles. You could do it with rows, whatever, same thing.
Make a new class called
Tile
in tile.js.
tile.js
Each tile will have
x
and
y
coordinates, a
sprite
(simply the numeric position in the spritesheet),
and a
passable
flag. For the most basic maps, all you need to know is how to distinguish between walls and floors and
passable
does that for us. You can also see that we're using
drawSprite
like we did for the player.
Let's extend
Tile
to make floors and walls.
tile.js
We have the code for floor and wall tiles, but we need the sprites.
Drawing Map Tiles
The floor uses dark colors and not too much contrast since we don't want it to compete with the foreground sprites. With tiles, keep in mind how they're going to repeat. Pixels on the left of our sprite will appear next to pixels on the right (likewise for bottom and top). An easy technique I'm using here is drawing a bunch of connecting lines and then breaking them up with a few pixels of the background color.
For the wall tile, we'll start with the same background color from the floor tile. This allows us to have rounded walls that blend in seamlessly.
Don't forget to export your file after updating it!
In map.js, we're going to start making the map.
index.html
map.js
This makes a 2D array called
tiles
and populates it with about 30% walls and 70% floors.
It does so by looping over the columns and then, for each column, looping over the rows and creating new wall/floor tiles in each spot as appropriate.
So our map is actually there and the way you can confirm this is by going into the dev tools and simply typing "tiles".
But let's draw it. All we need to do is iterate over every tile and call
draw
on it.
But first, I want to wrap access to the tile array in a function called
getTile
. There are a lot of reasons for doing this. For one it reads a little cleaner, but it also lets us pull off shenanigans like returning tiles outside the bounds of the array and which don't actually exist (which might happen if, for instance, the player casts a giant area of effect spell that extends past the outer dungeon walls).
map.js
Now with that out of the way, we can get to drawing simply by looping over each tile and telling it to draw itself.
game.js
Cool. We haven't added an outer wall though. Let's reuse the
inBounds
function to make one.
map.js
Only thing is the walls are not doing anything. We start on a wall and we're walking right through them!
To fix that first problem, we're simply going to teleport the player to a random floor tile when the game starts.
How do we find a random floor tile though? One really dumb, easy way to do so is repeatedly grab random tiles until we find a floor tile. This pattern works really well for a variety of map generation techniques: try to do something at random and keep doing it until we get it right. Add a timeout to make sure we don't get stuck in an infinite loop on accident. You don't want to lock up your browser after all.
We'll also need a simple utility function to generate random integers within a given range.
util.js
map.js
Our
tryTo
function needs to be passed a callback that attempts something and returns
true
only if it worked. That's why we're passing an anonymous function that rolls some random coordinates, gets the corresponding tile, and returns true only if the following expression is true:
tile.passable && !tile.monster
(the tile is passable and has no monster).
Notice that nowhere else in our program have we defined
tile.monster
. Thanks to JavaScript's lenient property and type handling, this will work fine. A missing property will have a value of
undefined
and that will get coerced to
false
and we're good.
Let's take
randomPassableTile
out for a spin by teleporting the player to random tile as mentioned earlier.
index.html
Refresh several times and you'll see that the player spawns in random locations, none of which are walls.
Our map is generated and our player is spawned in the correct place. We're almost done.
Banishing disconnected islands (a roguelike developer's greatest enemy)
One more big problem first and this one is a super common headache when procedurally generating the maps. With our extremely dumb way of making the levels, there are often areas of the map not connected to other areas. Disconnected islands. We need a way a check that everything is connected.
This part is a little tricky, so first let's some write some pseudocode:
That's the basic idea. Now let's convert that into real code:
map.js
They key here is
getConnectedTiles
.
Imagine you are drawing a dungeon map on grid paper and you want to color in all the connected floor spaces. How would you do it?
One way is pick a random floor tile on the grid, expand outwards repeatedly, and color connected floor tiles until you're done. You obviously would ignore wall tiles and you wouldn't recolor floor tiles once you drew them the first time. That's exactly the idea behind the flood fill algorithm and here's more pseudocode for a function that does it:
We'll convert that to JavaScript as well by breaking it down into several smaller functions:
tile.js
OK, that seems like a lot so let's break it down.
getNeighbor
is pretty straightforward. It's a wrapper around
getTile
. Even though it's a simple wrapper,
this method is useful when implementing all sorts of mechanics. Also note that it works for more than just adjacent neighbors.
getAdjacentNeighbors
returns the adjacent neighbors of a tile and shuffles them before returning.
getAdjacentPassableNeighbors
additionally filters out non-passable tiles (e.g. walls).
filter
is a nifty JavaScript array function where we pass in a callback and we return true for only the elements we want to keep.
getConnectedTiles
does exactly what the pseudocode said. It uses
filter
again and also
concat
,
which adds one array to another.
util.js
And finally
shuffle
is an implementation of Fisher-Yates shuffle. All it's doing is a random swap for each element in an array, leading to a perfectly shuffled array.
To reiterate: we keep trying to make levels until we find one that has no disconnected islands. The way we know there are no disconencted islands is when we've made only a single connected "island". If we have one big island of floor tiles, the number of tiles on that island should match the total number of floor tiles on the map. When we're able to satisfy that condition, we're happy with our level and we can stop.
So now let's check our work. Refresh a bunch of times and you'll never see a disconnected island again.
Just for fun, you might try out different values of
numTiles
. Here's what I got with a value of 24 (much higher and the timeout was usually reached):
In the next section, we'll create our monsters and make sure the player can't walk through walls.


Fried rice is a staple of Asian cuisine. This is one of those dishes whose amazing smell betrays the minimal effort required of it. There are plenty of variations so it's a good dish to experiment wish, and pretty much anything goes. Here's what I use, but feel free to mix and match with whatever you like and whatever you have in your fridge.
What You Need
- 1/2 - 1 cup (around 100g) roast pork or ham
- 1 - 1 1/2 cups plain cooked rice
- 1 cup chopped non-aromatic vegetables - bell pepper, zucchini, basically anything with a bit of crunch.
- 1 cup chopped green onions
- 2 medium eggs
- salt and pepper
- 1 Tbsp soy sauce
- 1 Tbsp cooking oil
What To Do
- Get all your ingredients ready to go before you start cooking - chop your meat and vegetables nice and small. Crack two eggs, add a little salt, and beat. Make sure your rice is cooked or warmed.
- Heat up your frying pan - high if it's electic, medium to medium high for gas. Make sure it's nice and hot before drizzling a little cooking oil in. Add the eggs and scramble them until they are just done - I prefer them just a little bit runny because you're going to add them back into the dish later. Plate them and set aside.
- You can give the pan a quick wipe with a spatula or paper towel, then add a little more oil.
- Throw in the non-aromatic vegetables and meat, and let it cook for a few minutes stirring it around occasionally.
- Add the green onions and season with salt and pepper.
- Throw in the cooked rice and spread it around the pan mixing it in with the other ingredients. If you like crispier rice like some Korean dishes, let it sit for a bit without stirring. Either way, let it cook for a few minutes.
- Clear a little hole in the center and slowly drizzle in the soy sauce - it should bubble up along the bottom of the pan. Mix the contents into the soy sauce trying to spread it around as best you can.
- Return the eggs to the pan, give it a good toss, and you're done.

How to use
Overview
The typical program flow of Haru is as
follows.
Initializing a
document object
First, invoke HPDF_New() or HPDF_NewEx() to
create
an instance of document object.
You can specify user-defined error function on this step. If you want to use user-define memory memory management function, use HPDF_NewEx().
The Handle which is returned from HPDF_New() or HPDF_NewEx() is used in the following steps.
You can call setjmp() for an exception handling after HPDF_New() succeed. (See the chapter of "Error Handling")
You can specify user-defined error function on this step. If you want to use user-define memory memory management function, use HPDF_NewEx().
The Handle which is returned from HPDF_New() or HPDF_NewEx() is used in the following steps.
You can call setjmp() for an exception handling after HPDF_New() succeed. (See the chapter of "Error Handling")
#include "apdf.h"
HPDF_Doc pdf;
pdf = HPDF_New (error_handler, NULL);
if (!pdf) {
printf ("ERROR: cannot create pdf object.\n");
return 1;
}
if (setjmp(env)) {
HPDF_Free (pdf);
return 1;
}
HPDF_Doc pdf;
pdf = HPDF_New (error_handler, NULL);
if (!pdf) {
printf ("ERROR: cannot create pdf object.\n");
return 1;
}
if (setjmp(env)) {
HPDF_Free (pdf);
return 1;
}
Setting a document
object
Set attributes of compression, encryption,
page mode and pages tree if necessary.
/* set compression mode */
HPDF_SetCompressionMode (pdf, HPDF_COMP_ALL);
/* set page mode to use outlines. */
HPDF_SetPageMode (pdf, HPDF_PAGE_MODE_USE_OUTLINE);
/* set password */
HPDF_SetPassword (pdf, "owner", "user");
HPDF_SetCompressionMode (pdf, HPDF_COMP_ALL);
/* set page mode to use outlines. */
HPDF_SetPageMode (pdf, HPDF_PAGE_MODE_USE_OUTLINE);
/* set password */
HPDF_SetPassword (pdf, "owner", "user");
Create a page
object
Call HPDF_AddPage() to add a
page to the
document. The page-handle which is returned by HPDF_AddPage() function
is used to operate a page.
page_1 = HPDF_AddPage (pdf);
When you want to insert a new page before an
existing page, call HPDF_InsertPage().
For example, in the case of
inserting "page_0" before "page_1", the code is as follows.
page_0 = HPDF_InsertPage (pdf, page_1);
Setting a page object
Set attributes of the page object if necessary.
HPDF_Page_SetSize (page_1,
HPDF_PAGE_SIZE_B5, HPDF_PAGE_LANDSCAPE);
Page description
You can perform drawing processing for a page.
For details, please refer to a chapter of "Graphics".
Save a document to file or
memory stream.
Call HPDF_SaveToFile()
to save a document to a
file.
If you don't want to save a document to a file, use HPDF_SaveToStream() instead. HPDF_SaveToStream() saves a document to a temporary stream.
An application can get the data saved by HPDF_SaveToStream() by invoking HPDF_ReadFromStream().
The following codes are examples of outputting the document directly to stdout.
/* save the document to a stream */
HPDF_SaveToStream (pdf);
fprintf (stderr, "the size of data is %d\n", HPDF_GetStreamSize(pdf));
/* rewind the stream. */
HPDF_ResetStream (pdf);

The criteria for acceptance includes, but is not limited to, space availability, similarity to other vendors, products to be sold, history with Town events and the best interests of the overall festival. Submitting an application does not guarantee you will be accepted.
Is the festival juried?
No, not exactly. Applications are not reviewed by a jury. However, we do have vendor contests. These contests are free to be included. The categories include: Food Fight, Original Work and Decor. Judges will choose the Best in Show winner from those categories. Everyone is automatically entered into the People’s Choice contests.
Will I receive a refund if I am not accepted?
The application fee is the only fee required prior to being notified of acceptance, and is non-refundable.
What if I can only do one day of the Festival?
Vendors are required to participate all day, both days. Exceptions may be granted on a case-by-case basis.
 What if I need more than one space?
Booths are 11’ wide by 10’ deep for artists & general vendors and 15’ wide by 10’ deep for food vendors. If you’re an artist or general vendor and you need 12’ of booth space, then you have to buy two booths. If you’re a food vendor and you need 16’, you have to buy two booths. You may not purchase more than 3 spaces.
*Food Vendors – please make sure you are accounting for the tongue of your trailer and clearance for opening doors or windows in total amount of space needed.
Back to Top
Can I share my booth with a friend?
Yes, you may share your booth with someone. That person is still required to submit an application and be approved to participate. How you elect to share the cost is up to you.
Do you provide tents, tables, chairs, etc.?
No, we do not. You will need to bring your own tent, table, chairs, rugs, extension cords, etc. Tents are required. Exceptions may be granted on a case-by-case basis. You are required to submit a photo of your setup with your application whether or not you use a tent. Uniqueness and creativity in your setup is encouraged.
What kind of tent can I use?
We only accept 10×10 straight leg tents. We do not accept 12×12 or larger, slanted legs or the fancy tents with the extra protruding sides. Stakes longer than 8 inches are strictly prohibited as they will damage our underground systems. Weights are strongly encouraged.
When will I get my booth assignment?
Booth assignments and other setup details will be sent via email no later than September 14, 2018. A vendor list with assignments will also be posted to the website.
What if I don’t have an email address?
Communication is done almost exclusively through email. You are required to have a valid email address. There are many ways to get and access a free account.
Do I have to have insurance to participate?
Activity providers and prepared-on-site food vendors are required to have insurance. Insurance to protect yourself from liability is strongly encouraged for other vendor types. You can find information on obtaining a policy on page five (5) of the application packet.

Features overview
GrapheneOS is a private and secure mobile operating system with great functionality and usability. It starts from the strong baseline of the Android Open Source Project (AOSP) and takes great care to avoid increasing attack surface or hurting the strong security model. GrapheneOS makes substantial improvements to both privacy and security through many carefully designed features built to function against real adversaries. The project cares a lot about usability and app compatibility so those are taken into account for all of our features.
GrapheneOS is focused on substance rather than branding and marketing. It doesn't take the typical approach of piling on a bunch of insecure features depending on the adversaries not knowing about them and regressing actual privacy/security. It's a very technical project building privacy and security into the OS rather than including assorted unhelpful frills or bundling subjective third party apps choices.
GrapheneOS is also hard at work on filling in gaps from not bundling Google apps and services into the OS. We aren't against users using Google services but it doesn't belong integrated into the OS in an invasive way. GrapheneOS won't take the shortcut of simply bundling a very incomplete and poorly secured third party reimplementation of Google services into the OS. That wouldn't ever be something users could rely upon. It will also always be chasing a moving target while offering poorer security than the real thing if the focus is on simply getting things working without great care for doing it robustly and securely.
This page provides an overview of currently implemented features differentiating GrapheneOS from AOSP. It doesn't document our many historical features that are no longer included for one reason or another. Many of our features were implemented in AOSP, Linux, LLVM and other projects GrapheneOS is based on and those aren't listed here. In many cases, we've been involved in getting those features implemented in core infrastructure projects.
GrapheneOS
These are the features of GrapheneOS beyond what's provided by version 13 of the Android Open Source Project. It only covers our improvements to AOSP and not baseline features. This section doesn't list features like the standard app sandbox, verified boot, exploit mitigations (ASLR, SSP, Shadow Call Stack, Control Flow Integrity, etc.), permission system (foreground-only and one-time permission grants, scoped file access control, etc.) and so on but rather only our improvements to modern Android. We plan on providing a separate page listing the improvements we've contributed to Android since those features aren't listed here despite being a substantial portion of our overall historical work.
Defending against exploitation of unknown vulnerabilities
GrapheneOS is heavily focused on protecting users against attackers exploiting unknown (0 day) vulnerabilities. Patching vulnerabilities doesn't protect users before the vulnerability is known to the vendor and has a patch developed and shipped.
Unknown (0 day) vulnerabilities are much more widely used than most realize to exploit users not just in targeted attacks but in broad deployments. Project Zero maintains a spreadsheet tracking zero day exploitation detected in the wild. This is only a peek into what's happening since it only documents cases where the attackers were caught exploiting users, often because the attacks are not targeted but rather deployed on public websites, etc.
The first line of defense is attack surface reduction. Removing unnecessary code or exposed attack surface eliminates many vulnerabilities completely. GrapheneOS avoids removing any useful functionality for end users, but we can still disable lots of functionality by default and require that users opt-in to using it to eliminate it for most of them. An example we landed upstream in Android is disallowing using the kernel's profiling support by default, since it was and still is a major source of Linux kernel vulnerabilities. Profiling is now only exposed to apps for developers who enable developer tools, enable the Android Debug Bridge (ADB) and then use profiling tools via ADB. It's also only enabled until the next boot. This isn't listed below since it's one of the features we got implemented in Android itself.
The next line of defense is preventing an attacker from exploiting a vulnerability, either by making it impossible, unreliable or at least meaningfully harder to develop. The vast majority of vulnerabilities are well understood classes of bugs and exploitation can be prevented by avoiding the bugs via languages/tooling or preventing exploitation with strong exploit mitigations. In many cases, vulnerability classes can be completely wiped out while in many others they can at least be made meaningfully harder to exploit. Android does a lot of work in this area and GrapheneOS has helped to advance this in Android and the Linux kernel. It takes an enormous amount of resources to develop fundamental fixes for these problems and there's often a high performance, memory or compatibility cost to deploying them. Mainstream operating systems usually don't prioritize security over other areas. GrapheneOS is willing to go further and we offer toggles for users to choose the compromises they prefer instead of forcing it on them. In the meantime, weaker less complete exploit mitigations can still provide meaningful barriers against attacks as long as they're developed with a clear threat model. GrapheneOS is heavily invested in many areas of developing these protections: developing/deploying memory safe languages / libraries, static/dynamic analysis tooling and many kinds of mitigations.
The final line of defense is containment through sandboxing at various levels: fine-grained sandboxes around a specific context like per site browser renderers, sandboxes around a specific component like Android's media codec sandbox and app / workspace sandboxes like the Android app sandbox used to sandbox each app which is also the basis for user/work profiles. GrapheneOS improves all of these sandboxes through fortifying the kernel and other base OS components along with improving the sandboxing policies.
Preventing an attacker from persisting their control of a component or the OS / firmware through verified boot and avoiding trust in persistent state also helps to mitigate the damage after a compromise has occurred.
Remote code execution vulnerabilities are the most serious and allow an attacker to gain a foothold on device or even substantial control over it remotely. Local code execution vulnerabilities allow breaking out of a sandbox including the app sandbox or browser renderer sandbox after either compromising an app / browser renderer remotely, compromising an app's supply chain or getting the user to install a malicious app. Many other kinds of vulnerabilities exist but most of what we're protecting against falls into these 2 broad categories.
The vast majority of local and remote code execution vulnerabilities are memory corruption bugs caused by memory unsafe languages or rare low-level unsafe code in an otherwise memory safe language. Most of the remaining issues are caused by dynamic code execution/loading features. Our main focus is on preventing or raising the difficulty of exploiting memory corruption bugs followed by restricting dynamic code execution both to make escalation from a memory corruption bug harder and to directly mitigate bugs caused by dynamic code loading/generation/execution such as a JIT compiler bug or a plugin loading vulnerability.
Attack surface reduction
- Greatly reduced remote, local and proximity-based attack surface by stripping out unnecessary code, making more features optional and disabling optional features by default (NFC, Bluetooth, UWB, etc.), when the screen is locked (connecting new USB peripherals, camera access) and optionally after a timeout (Bluetooth, Wi-Fi)
- Option to disable native debugging (ptrace) to reduce local attack surface (still enabled by default for compatibility)
Exploit mitigations
- Hardened app runtime
- Secure application spawning system avoiding sharing address space layout and other secrets across applications
- Hardened libc providing defenses against the most common classes of vulnerabilities (memory corruption)
-
Our own hardened
malloc (memory allocator) leveraging modern hardware capabilities
to provide substantial defenses against the most common classes of
vulnerabilities (heap memory corruption) along with reducing the lifetime
of sensitive data in memory. The hardened_malloc
README has extensive documentation on it. The hardened_malloc
project is portable to other Linux-based operating systems and is being
adopted by other security-focused operating systems like Whonix. Our
allocator also heavily influenced the design of the next-generation
musl malloc implementation which offers substantially better security than
musl's previous malloc while still having minimal memory usage and code size.
- Fully out-of-line metadata with protection from corruption, ruling out traditional allocator exploitation
- Separate memory regions for metadata, large allocations and each slab allocation size class with high entropy random bases and no address space reuse between the different regions
- Deterministic detection of any invalid free
- Zero-on-free with detection of write-after-free via checking that memory is still zeroed before handing it out again
- Delayed reuse of address space and memory allocations through the combination of deterministic and randomized quarantines to mitigate use-after-free vulnerabilities
- Fine-grained randomization
- Aggressive consistency checks
- Memory protected guard regions around allocations larger than 16k with randomization of guard region sizes for 128k and above
- Allocations smaller than 16k have guard regions around each of the slabs containing allocations (for example, 16 byte allocations are in 4096 byte slabs with 4096 byte guard regions before and after)
- Random canaries with a leading zero are added to these smaller allocations to block C string overflows, absorb small overflows and detect linear overflows or other heap corruption when the canary value is checked (primarily on free)
- Hardened compiler toolchain
-
Hardened kernel
- 4-level page tables are enabled on arm64 to provide a much larger address space (48-bit instead of 39-bit) with significantly higher entropy Address Space Layout Randomization (33-bit instead of 24-bit).
- Random canaries with a leading zero are added to the kernel heap (slub) to block C string overflows, absorb small overflows and detect linear overflows or other heap corruption when the canary value is checked (on free, copies to/from userspace, etc.).
- Memory is wiped (zeroed) as soon as it's released in both the low-level kernel page allocator and higher level kernel heap allocator (slub). This substantially reduces the lifetime of sensitive data in memory, mitigates use-after-free vulnerabilities and makes most uninitialized data usage vulnerabilities harmless. Without our changes, memory that's released retains data indefinitely until the memory is handed out for other uses and gets partially or fully overwritten by new data.
- Kernel stack allocations are zeroed to make most uninitialized data usage vulnerabilities harmless.
- Assorted attack surface reduction through disabling features or setting up infrastructure to dynamically enable/disable them only as needed (perf, ptrace).
- Assorted upstream hardening features are enabled, including many which we played a part in developing and landing upstream as part of our linux-hardened project (which we intend to revive as a more active project again).
- Forced kernel module signing with per-build RSA 4096 / SHA256 keys and lockdown mode set to forced confidentiality mode help to enforce a low-level boundary between the kernel and userspace even if mistakes are made in SELinux policy or there's a deep userspace compromise.
- Additional consistency / integrity checks are enabled for frequently targeted kernel data structures.
- Android Runtime Just-In-Time (JIT) compilation/profiling is fully disabled and replaced with full ahead-of-time (AOT) compilation. The only JIT compilation in the base OS is the v8 JavaScript JIT which is disabled by default for the Vanadium browser with per-site exception support.
- Prevention of dynamic native code execution via either memory or storage for the base OS including nearly all the base OS apps. For the OS itself, only the processes involved in the OS package management system can write data to storage that can be executed and only the media DRM sandbox can do in-memory dynamic native code execution. The Vanadium browser and WebView are excluded in order to support the JS JIT compiler.
- Filesystem access hardening
Improved sandboxing
GrapheneOS improves the app sandbox through hardening SELinux policy and seccomp-bpf policy along with all the hardening to components like kernel implementing the app sandbox and providing a path for the attacker to escape it if they can exploit those components. We primarily focus on the app sandbox, but we also improve the other sandboxes including making direct improvements to the web browser renderer sandbox used for both the default browser and WebView rendering engine provided by the OS and used by a huge number of other apps from dedicated browsers to messaging apps.
Anti-persistence / detection
- Enhanced verified boot with better security properties and reduced attack surface
- GrapheneOS finishes the incomplete implementation of verified boot for out-of-band updates to packages (APKs) in the OS. We enforce this by requiring fs-verity metadata signed with a trusted key for system app updates both at install time and boot time. This provides continuous verification where every read from an out-of-band APK update is verified similarly to every read from a firmware, OS image or APEX update being verified. The signing key and version are enforced to prevent downgrades or other attacks such as replacing a package with a variant of the same one from a different GrapheneOS supported device. We disable the persistent package parsing cache to prevent bypassing the metadata checks through this otherwise highly persistent state, which only has a very small negative impact on boot time from the data not being available from previous boots (typically less than 1 second).
- GrapheneOS closes a loophole where app-based system components built as part of the OS can be downgraded to an older version due to versionCode not being incremented when system components get updated as part of changes to the OS. We enforce this both at package install time and boot time.
- Enhanced hardware-based attestation with more precise version information
- Hardware-based security verification and monitoring via our Auditor app and attestation service
- Compressed APEX module support is disabled as it's not useful for GrapheneOS, uses extra unnecessary storage space and adds more verified boot attack surface.
More complete patching
GrapheneOS includes fixes for a large number of vulnerabilities not yet fixed in Android.
We're able to quickly and safely ship the latest Linux kernel LTS point releases on devices with GKI (Generic Kernel Image) support including the 6th and 7th generation Pixel phones. At the time of writing on 2023-02-23, GrapheneOS is using the latest Linux 5.10 GKI LTS release (5.10.168) for 6th and 7th generation Pixel phones. The stock Pixel OS is on Linux 5.10.107 from 2022-03-19 with a small number of additional patches backported. This means GrapheneOS provides hundreds of relevant kernel patches including many security patches not yet included in the stock OS. It's possible for us to stay several months ahead due to their approach of moving to new LTS releases only in quarterly releases after a long freeze and testing process.
We often find new vulnerabilities ourselves and report them upstream. We've reported dozens of vulnerabilities for both the generic Android codebase and also for Pixels specifically. We also often find missed patches which were supposed to be included but were missed, especially when there are device specific components with partially shared but separate codebases for different devices.
Our overall approach is to focus on systemic privacy and security improvements but fixing individual vulnerabilities is still very important.
Sandboxed Google Play
GrapheneOS has a compatibility layer providing the option to install and use the official releases of Google Play in the standard app sandbox. Google Play receives absolutely no special access or privileges on GrapheneOS as opposed to bypassing the app sandbox and receiving a massive amount of highly privileged access. Instead, the compatibility layer teaches it how to work within the full app sandbox. It also isn't used as a backend for the OS services as it would be elsewhere since GrapheneOS doesn't use Google Play even when it's installed.
Since the Google Play apps are simply regular apps on GrapheneOS, you install them within a specific user or work profile and they're only available within that profile. Only apps within the same profile can use it and they need to explicitly choose to use it. It works the same way as any other app and has no special capabilities. As with any other app, it can't access data of other apps and requires explicit user consent to gain access to profile data or the standard permissions. Apps within the same profile can communicate with mutual consent and it's no different for sandboxed Google Play.
Sandboxed Google Play is close to being fully functional and provides near complete compatibility with the app ecosystem depending on Google Play. Only a small subset of privileged functionality which we haven't yet ported to different approaches with our compatibility layer is unavailable. Some functionality is inherently privileged and can't be provided as part of the compatibility layer.
The vast majority of Play services functionality works perfectly including dynamically downloaded / updated modules (dynamite modules) and functionality provided by modular app components such as Google Play Games. By default, location requests are rerouted to a reimplementation of the Play geolocation service provided by GrapheneOS. You can disable rerouting and use the standard Play services geolocation service instead if you want the Google network location service and related features.
Our compatibility layer includes full support for the Play Store. Play Store services are fully available including in-app purchases, Play Asset Delivery, Play Feature Delivery and app / content license checks. It can install, update and uninstall apps with the standard approach requiring that the user authorizes it as an app source and consents to each action. It will use the standard Android 12+ unattended update feature to do automatic updates for apps where it was the last installer.
See the usage guide section on sandboxed Google Play for instructions.
Network permission toggle
GrapheneOS adds a Network permission toggle for disallowing both direct and indirect access to any of the available networks. The device-local network (localhost) is also guarded by this permission, which is important for preventing apps from using it to communicate between profiles. Unlike a firewall-based implementation, the Network permission toggle prevents apps from using the network via APIs provided by the OS or other apps in the same profile as long as they're marked appropriately.
The standard INTERNET permission used as the basis for the Network permission toggle is enhanced with a second layer of enforcement and proper support for granting/revoking it on a per-profile basis.
To avoid breaking compatibility with Android apps, the added permission toggle is enabled by default. However, the OS app installation UI has been extended to show the toggle as part of the installation confirmation page so users can disable it when installing an app.
Sensors permission toggle
Sensors permission toggle: disallow access to all other sensors not covered by existing Android permissions (Camera, Microphone, Body Sensors, Activity Recognition) including an accelerometer, gyroscope, compass, barometer, thermometer and any other sensors present on a given device. When access is disabled, apps receive zeroed data when they check for sensor values and don't receive events. GrapheneOS creates an easy to disable notification when apps try to access sensors blocked by the permission being denied. This makes the feature more usable since users can tell if the app is trying to access this functionality.
To avoid breaking compatibility with Android apps, the added permission is enabled by default. When an app attempts to access sensors and receives zeroed data due to being denied, GrapheneOS creates a notification which can be easily disabled. The Sensors permission can be set to be disabled by default for user installed apps in Settings ➔ Privacy.
Storage Scopes
GrapheneOS provides Storage Scopes as a fully compatible alternative to the standard Android storage permissions. Instead of granting storage permissions, users can enable Storage Scopes to make the app assume that it has all storage permissions that it asked for. On Android, an app that doesn't have any storage permissions is still allowed to create files and directories, and is allowed to access the files that it created. Users can optionally add files and directories as storage scopes to permit the app to access files created by other apps.
For more details, see the usage guide section on storage access.
Contact Scopes
GrapheneOS provides Contact Scopes as an alternative to granting the Contacts permission. By default, it acts as if the contacts list is empty and users can grant different kinds of access to specific contacts or groups of contacts.
Broad carrier support without invasive carrier access
GrapheneOS has much broader carrier support than AOSP and mostly matches the stock OS on Pixels without making the same sacrifices. We convert their APN, carrier configuration, MMS and visual voicemail databases to the formats used by AOSP with our carriersettings project and other scripts. We strip out anti-user configuration requiring provisioning for tethering, forbidding disabling 2G, etc. We don't include the invasive carrier specific apps and support for Open Mobile Alliance Device Management (OMA DM) so we also strip out configuration depending on those.
See our usage guide section on carrier functionality for more details.
LTE-only mode
LTE-only mode to reduce cellular radio attack surface by disabling enormous amounts of both legacy code (2G, 3G) and bleeding edge code (5G).
Wi-Fi privacy
GrapheneOS supports per-connection MAC randomization and enables it by default. This is a more private approach than the standard persistent per-network random MAC used by modern Android.
When the per-connection MAC randomization added by GrapheneOS is being used, DHCP client state is flushed before reconnecting to a network to avoid revealing that it's likely the same device as before.
GrapheneOS also applies fixes for serious flaws with the Linux kernel IPv6 privacy address implementation which allow using it as an identifier not just for connections to the same network but also across different networks. We don't need to apply these changes for the Pixel 6 and later since this was fixed in the Linux kernel upstream, but hasn't been backported to earlier kernel LTS branches so we still need to take care of it there.
See our usage guide section on Wi-Fi privacy for more general information rather than only our improvements to the standard Wi-Fi privacy approach.
Private screenshots
GrapheneOS disables the inclusion of sensitive metadata in screenshots.
On Android, each screenshot includes an EXIF Software tag with detailed OS
build/version information (android.os.Build.DISPLAY
). It's the
same value shown at Settings ➔ About device ➔ Build number. This leaks the OS,
OS version and also usually the device family/model since builds are usually
specific to a family of devices. GrapheneOS completely disables this tag.
On Android, each screenshot also includes EXIF tags with the local date, time and timezone offset. GrapheneOS disables this by default in order to avoid leaking the time and quasi-location information through metadata that isn't visible to the user. The date and time are already included in the file name of the screenshot which is fully visible to the user and can be easily modified by them without a third party tool. GrapheneOS includes a toggle for turning this metadata back on in Settings ➔ Privacy since some users may find it to be useful.
Closed device identifier leaks
GrapheneOS fixes several prominent device identifier leaks bypassing Android's intention of apps not being able to uniquely identify a device. See our FAQ sections on hardware identifiers and non-hardware identifiers for more general information.
Our secure application spawning system primarily exists to significantly improve protection against exploitation. However, it also improves privacy. On a device without our secure application spawning system, the secrets used for probabilistic exploit mitigations such as ASLR are usable as device identifiers persisting until reboot. This is an easy way to identify the device from apps in different profiles. It's a minor bonus of the feature and there are still plenty of side channels to identify devices across apps, but it fixes most of the known direct identifier leaks.
We also eliminate several holes in preventing apps from accessing hardware identifiers including tightening up the restrictions for apps targeting legacy Android platform versions.
PIN scrambling
GrapheneOS adds a toggle for enabling PIN scrambling to raise the difficulty of figuring out the PIN being entered by a user either due to physical proximity or a side channel. PIN scrambling is applied to both the lock screen and SIM PIN/PUK.
Privacy by default
GrapheneOS doesn't include or use Google apps and services by default and avoids including any other apps/services not aligned with our privacy and security focus. Google apps and services can be used on GrapheneOS as regular sandboxed apps without any special access or privileges through our sandboxed Google Play feature, but we don't include those apps by default to give users an explicit choice on whether they want to use those apps and which profiles they want to use it in.
We change the default settings to prefer privacy over small conveniences: personalized keyboard suggestions based on gathering input history are disabled by default, sensitive notifications are hidden on the lockscreen by default and passwords are hidden during entry by default.
Some of our changes for attack surface reduction can also improve privacy by default by not exposing unnecessary radios, etc. by default and avoiding the impact of potential privacy bugs with the hardware.
By default, we also use GrapheneOS servers for the following services instead of Google servers:
- Connectivity checks
- Attestation key provisioning
- GNSS almanac downloads (PSDS) for Broadcom and Qualcomm (XTRA)
- Secure User Plane Location (SUPL)
- Network time
- Vanadium (Chromium) component updates
We provide a toggle to switch back to Google's servers for connectivity checks, attestation key provisioning and GNSS almanac downloads along with adding proper support for disabling network time connections. This combines with other toggles to allow making a GrapheneOS device appear to be an AOSP device. This is only particularly important for connectivity checks since the other connections get routed through a VPN which is needed to blend in on a local network in practice.
In addition to our SUPL privacy improvements, we override the SUPL server to our proxy by default. We also add a toggle for users to switch to the standard SUPL server for their carrier (usually supl.google.com) or disable it entirely.
See our default connections FAQ entry for much more detailed information.
Supports longer passwords
GrapheneOS supports setting longer passwords by default: 64 characters instead of 16 characters. This avoids the need to use a device manager to enable this functionality.
This feature allows users to make use of diceware passwords if they don't want to depend on the security of the secure element which provides very aggressive throttling and offers a high level of security even for a random 6 digit PIN.
Auto reboot
Option to enable automatically rebooting the device when no profile has been unlocked for the configured time period to put the device fully at rest again, which is enabled by default at 72 hours.
More secure fingerprint unlock
GrapheneOS improves the security of the fingerprint unlock feature by only permitting 5 total attempts rather than implementing a 30 second delay between every 5 failed attempts with a total of 20 attempts. This doesn't just reduce the number of potential attempts but also makes it easy to disable fingerprint unlock by intentionally failing to unlock 5 times with a different finger.
GrapheneOS also adds support for using the fingerprint scanner only for authentication in apps and unlocking hardware keystore keys by toggling off support for unlocking. This feature already existed for the standard Android face unlock feature.
Improved user profiles
Android's user profiles are isolated workspaces with their own instances of apps, app data and profile data (contacts, media store, home directory, etc.). Apps can't see the apps in other user profiles and can only communicate with apps within the same user profile (with mutual consent with the other app). Each user profile has their own encryption keys based on their lock method. They're a great fit for GrapheneOS with a lot of room for improvement.
GrapheneOS provides improvements to user profile functionality and is working on further improvements to make switching between them and monitoring other profiles much more convenient.
More user profiles
GrapheneOS raises the limit on the number of secondary user profiles to 32 (31 + guest) instead of only 4 (3 + guest) to make this feature much more flexible.
End session
GrapheneOS also enables support for logging out of user profiles without needing a device manager controlling the device to use this feature. Logging out makes profiles inactive so none of the apps installed in them can run. It also purges the disk encryption keys from memory and hardware registers, putting the user profile back at rest.
Disabling app installation
GrapheneOS adds a toggle to the user management settings for disabling secondary user app installation. You can install the apps you want to be usable in a secondary user and then disable the ability to install more apps as that user in the Owner profile. Android supports this as a standard device management feature but doesn't make it available to a user who owns their own device.
Improved install available apps
GrapheneOS enables the standard install available apps feature that's still not enabled in AOSP or the stock Pixel OS to allow the Owner user to install packages that are available in other users. This allows installing an app in a secondary user that's already installed in the Owner user without needing to download it again. This helps a lot with using the toggles added for disabling app installation by secondary users.
Notification forwarding
GrapheneOS supports forwarding notifications from users running in the background to the currently active user. Forwarding notifications to other users is disabled by default and can be enabled within each user profile where forwarding to the active profile is wanted. Notifications forwarded from other profiles are displayed by default in a standard local notification channel.
GrapheneOS app repository
GrapheneOS includes our own security, minimalism and usability focused app repository client for using our first party app repository. Our app repository is currently used to distribute our own apps and a mirror of Google Play for the sandboxed Google Play feature. In the future, it will be used to distribute first-party GrapheneOS builds of externally developed open source apps with hardening applied.
Vanadium: hardened WebView and default browser
GrapheneOS includes our Vanadium browser as WebView implementation provided by the OS and our default browser. Vanadium is a hardened variant of Chromium providing enhanced privacy and security, similar to how GrapheneOS compares to AOSP. The Vanadium browser currently doesn't add many features but there are a lot of enhancements planned in the long term.
More details are available in the web browsing section of our usage guide.
Auditor app and attestation service
Our Auditor app and attestation service provide strong hardware-based verification of the authenticity and integrity of the firmware/software on the device. A strong pairing-based approach is used which also provides verification of the device's identity based on the hardware backed key generated for each pairing. Software-based checks are layered on top with trust securely chained from the hardware. For more details, see the about page and tutorial.
GrapheneOS Camera
GrapheneOS Camera is a modern camera app with a great user interface and a focus on privacy and security. More details are available the camera section of our usage guide.
GrapheneOS PDF Viewer
GrapheneOS PDF Viewer is a sandboxed, hardened PDF viewer using HiDPI rendering with features like pinch to zoom, text selection, viewing encrypted PDFs, etc.
Encrypted backups
Encrypted backups via integration of the Seedvault app with support for local backups and any cloud storage provider with a storage provider app.
Seedvault was created by a GrapheneOS community member for inclusion in our operating system. We plan on replacing it with a new implementation since the project has been taken over by another group of people not sharing our goals or approach. For now, this is the best available option so we're including it to give people encrypted backup support. We've made several security fixes to work around upstream issues with the project.
Location data access indicator
GrapheneOS enables the privacy indicator for location data access in addition to the standard Android camera and microphone indicators. This shows an indicator when an app the user has granted permission to access location requests location data. We also resolve various UX issues with this feature as it currently exists in AOSP to get it into a highly usable state.
Android 13 has the location privacy indicator as a developer option but it doesn't work the same way as it does in GrapheneOS. GrapheneOS shows it for all location data accesses through any APIs. Normally, the stock OS only shows it for GNSS location requests, also known as high power location requests, and doesn't normally show it for network location and other APIs gated by the Location permission / global block toggle.
The indicator works the same way as the Camera and Microphone ones, showing a bright green icon when location access occurs which then gets minimized to a small bright green dot when the quick settings tray isn't currently opened. Android 12 already includes Location with the other standard runtime permissions in the privacy dashboard for viewing the history.
User installed apps can be disabled
GrapheneOS adds support for disabling user installed apps instead of only being able to disable system apps. This allows users to completely prevent one of the apps they've installed from being able to run without being forced to uninstall it and lose their app data. This is much stricter than the standard force stop feature which only prevents an app from starting itself and the app will start running again as soon as another app tries to open an activity or service it provides.
Other features
This is an incomplete list of other GrapheneOS features.
- Per-profile encrypted file name padding increased from 16 bytes to 32 bytes to reduce the information leaked through file name lengths. See the FAQ section on the filesystem-based full disk encryption used by modern Android and GrapheneOS for more information.
- Improved user visibility into persistent firmware security through version and configuration verification with reporting of inconsistencies and debug features being enabled.
- Authenticated encryption for network time updates via a first party server to prevent attackers from changing the time and enabling attacks based on bypassing certificate / key expiry, etc.
- Proper support for disabling network time updates rather than just not using the results
- Hardened local build / signing infrastructure
- Seamless automatic OS update system that just works and stays out of the way in the background without disrupting device usage, with full support for the standard automatic rollback if the first boot of the updated OS fails
- Require unlocking to access sensitive functionality via quick tiles
- Minimal bundled apps and services. Only essential apps are integrated into the OS. We don't make partnerships with apps and services to bundle them into the OS. An app may be the best choice today and poor choice in the future. Our approach will be recommending certain apps during the initial setup, not hard-wiring them into the OS.
- Wireless alerts are fully optional since GrapheneOS adds a toggle for the otherwise mandatory presidential alert type. This is particularly useful in Canada where the government abuses the system and sends every type of alert as a presidential alert to stop users from being able to opt out of weather and amber alerts.
- Removal of TrustCor root certificate authority as a trusted system CA.
- Secure-by-default Android 12 PendingIntent security check (FLAG_IMMUTABLE) instead of crash-by-default improving older app compatibility and security.
- Fixed UART debugging enabled warning on offical release builds.
- Engineering / Prototype ("EVT", "PVT" or "DVT") device warning as these
devices typically have relaxed security controls for development, mainly
the secure boot state property
ro.boot.secure_boot
not set toPRODUCTION
. - Enable bootloader, radio, and boot partition version / fingerprint checks.
- Remove code automatically granting the location permission to system browsers.
- Apps that don't have any storage permission aren't allowed to read the list of all user-created directories (this is allowed on Android). The list of files is hidden from such apps on both Android and GrapheneOS.
- Screenshot shutter sound is toggleable using the "Touch sounds" option in Settings ➔ Sound & vibration while still following the standard method of putting the device on vibration/silent mode to turn off the screenshot shutter sound.
- More precise system clock via lowering the system clock time update threshold from 2000ms to 50ms and lowering the system clock drift warning from 2000ms to 250ms. This can be helpful for time-based protocols such as TOTP.
- Call recording functionality within the Dialer app using modern Android storage with recordings stored in Recordings/Call Recordings and no restrictions based on region or special cases like playing a recording tone (users are still responsible for complying with their local laws).
- Change standard Android package installer behavior to preserving packages being disabled after updating them instead of them being re-enabled.
Services
Service infrastructure features:
- Strict privacy and security practices for our infrastructure
- Unnecessary logging is avoided and logs are automatically purged after 4 days (network services used by the OS) to 10 days
- Services are hosted entirely via our own dedicated servers and virtual machines from OVH without involving any additional parties for CDNs, SaaS platforms, mirrors or other services

domains permitting only Let's Encrypt to issue certificates with fully
integrated support for the
accounturi
andvalidationmethods
pinning our Let's Encrypt accounts as the only ones allowed to issue certificates - DANE TLSA records for pinning keys for all our TLS services
- Our mail server enforces DNSSEC/DANE to provide authenticated encryption when sending mail including alert messages from the attestation service
- SSHFP across all domains for pinning SSH keys
- Static key pinning for our services in apps like Auditor
- Our web services use robust OCSP stapling with Must-Staple
- No persistent cookies or similar client-side state for anything other than
login sessions, which are set up securely using
SameSite=Strict
,Secure
,HttpOnly
, andPath=/
flags, prefixed with__Host
and have server-side session tracking with the ability to log out of other sessions - scrypt-based password hashing (likely Argon2 when the available implementations are more mature)
Project
Beyond the technical features of the OS:
- Collaborative, open source project with a very active community and contributors
- Can make your own builds and make desired changes, so you aren't stuck with the decisions made by the upstream project
- Non-profit project avoiding conflicts of interest by keeping commercialization at a distance. Companies support the project rather than the project serving the needs of any particular company
- Strong privacy policies across all our software and services
- Proven track record of the team standing up against attempts to compromise the integrity of the project and placing it above personal gain

Boy killed by ice sculpture fall at Luxembourg market
A two-year-old boy has died after an ice sculpture fell on him at Luxembourg city's Christmas market.
Police said the child was severely injured in the incident which occurred yesterday and died in the ambulance.
Today, the city announced all street markets would be closed for the day and an investigation has been opened.
French sculptor Samuel Girault was questioned by Luxembourg police. He said his sculpture could not have fallen by itself.
Mr Girault said he had 19 years' experience in carving ice and the base of the fallen work weighed two tonnes.
The accident happened just metres from the ice rink at the capital city's annual Christmas fair which opened last Thursday.

I have been able to create Android applications, coupled with the ability of implementing Xml files, relevant designs, customizable code and easy-to-navigate pages. Every work that I have managed to do bears a mark of excellency.
Git helps me keep track of the changes I make to my code. It is essentially the history channel for my code editor. If it happens that I hit a fatal error and don’t know the cause, I can always revert to my former stable state.
I have enough skill set to create databases using SQL, in tandem with ensuring that the tables work fine, relevant designs, customizable code and easy-to-navigate tables. I have mastery of skill in writing Sql commands when creating databases.
Would you like to know more or just discuss something?
I have worked on dozens of projects so I have picked only the latest for you.
This project is an angular application that allows a user to add quotes to a list on which votes can be cast to individual quotes and the users can view the most liked quote. The user can also toggle between views to see what the author's name is. The toggle also shows the number of up-votes and down-votes. The quotes can also be deleted at a user's discretion. The user can also see the period that has elapsed since a particular quote was submitted.
The project describes an application which allows a user to enter his name, visit the page containing various exercises in a list an can be able to create a search from the list and also there is the ability of a user to add an activity to a favorite list by a click. The application also provides for the user to search gymnasiums by a zip code and also search youtube health and fitness tutorials. The application implements the use of Firebase database and Firebase Authentication.
The application deals with the ability of a user to search for a github useR. If the searched user is present, the information about the user's personal details and including the respective repositories are then displayed on the page.The application implements the usu of loaders, and it is written in TypeScript.

If you innovate transparently, you may have to upgrade intuitively.
We believe we know that if you incentivize intuitively then you may also optimize interactively. If all of this may seem misleading to you, that's because it is! We will utilize the term "proactive". We think that most C2C2C portals use far too much ActionScript, and not enough SVG. Quick: do you have a 24/7/365 game plan for handling unplanned-for action-items?
Graphikaria is the industry leader of e-business metrics. We will reinvent the buzzword "real-world". Without appropriate visionary, out-of-the-box research and development, distributed web-readiness are forced to become out-of-the-box, extensible. What do we redefine? Anything and everything, regardless of obscureness! The metrics for next-generation mission-critical, real-world implementation are more well-understood if they are not 60/24/7/365. We always drive innovative relationships.
We're here to help you succeed
Methodology:
Processes:
Progress:
We think that most transparent splash pages use far too much XHTML, and not enough Unix.


Getting Started
Hello and Welcome!
Installation
The library is available as npm package, so all you need to do is to run the following command:
{{ snippets.install }}
This command will create a record in your `package.json` file and install the package into the npm modules folder.
Examples
Minimal Setup Example
First thing you need to do is to import the ngx-material-table directives into your component.
{{ snippets.require }}
Then register it by adding to the list of directives of your module:
{{ snippets.directive }}
Now, we need to configure the table and add it into the template. The only required setting for the
component to start working is a columns configuration.
Let's register settings property inside of the component where we want to have the table and configure some
columns (Settings documentation):
{{ snippets.settings }}
Finally let's put the ngx-material-table component inside of the template:
{{ snippets.template }}
At this step you will have a minimally configured table which should look something like this:
All functions are available by default and you don't need to configure them somehow, so you already able to add/edit/delete rows, sort or filter the table, etc.
But it feels like something is missing... Right, there is no data in the table by default. To add some, let's create an array property with a list of objects in the component. Please note that object keys are same as in the columns configuration.
{{ snippets.array }}
And pass the data to the table:
{{ snippets.dataTemplate }}
Now you have some data in the table:
That's it for a minimal setup, our final component should look like this, pretty simple, huh?
Demo Source
{{ snippets.basicFull }}
Full component documentation you can find here.

All of us coffeesnobs have been there. You go to a new city and need to find the nearest (or not so nearest) place to get your coffee. The Charbucks around the corner is definitely not an option. You turn to Yelp and find the local 4.5 star coffeeshop. It has friendly baristas, lot of seating, free wifi, but can you trust the baristas to know how to make a good espresso or cappuccino? Yes they have the La Marzocco machine up front, and Stumptown or Intelligentsia beans on display but then you hear the sound of milk being destroyed while being steamed and you know you're in the wrong place. You go back to Yelp, read some more reviews of other nearby places, look through the photos to see if any of them can do decent latteart, but are quickly running out of patience and time. This is where the magic of machine learning comes in.

Start with a known "population". In this case our values are textbook
costs for one semester at MSU in 10's of dollars.
We start with confidence level 95% and sample size n =
8. Change them later if you wish.
Click "Sample" and watch values get pulled from the population
to the sample below.
The population then disappears, because in real data collection we
never know it.
Bootstrap resamples are based on just the one sample.
Click "1 Resample". You'll see a re-sample of size 8 get selected
from the original sample with replacement. Some of the items in the
sample get chosen multiple times (giving a darker background), and
some not at all (background stays white). The mean of
the resample is shown as a point in the plot. Click "slower" or
"faster" to vary the speed.
We'll need many samples, so click one
of the "Many Resamples" options. Only the resample means are shown.
A confidence interval appears on the plot as red boundary
lines. It's computed by the "percentile" method.
Note: in real applications, we only get one sample, but for a demo, this is needed to change sample size.
