Rails, often associated with Ruby on Rails, is an open source web application framework written in Ruby. It utilizes Model-View-Controller (MVC) architecture to organize web application programming, and its design makes programming web applications easier by making assumptions about the needs of developers. It allows one to write less code while achieving the same or even greater results when compared to many other languages and frameworks. To better understand Rails, you need to know more about Model-View-Controller framework. MVC is a way of organizing code to conceal complexity and facilitating the implementation of user interfaces. It separates the software application into three interconnected sections: the model, the controller, and the view. Ruby on Rails takes all three of these concepts and packages them together, and developers only need to install the rails gem to have this full development environment for writing web applications. The Model The Model handles all the database interaction in your web application. It retrieves and stores all objects from the database and also manages data integrity issues. For example, if you tried to enter a negative integer into a field that is not suppose to contain negative integers, the code in the Model would reject to implement this action. Controller The Controller handles all the web server interaction and assumes its role as the conduit between the Model and the View. It can grab an object from the database through the Model and then push it to the View, which will render it. Basically, it can send commands to both the Model and the Viewer to either change the Model’s state (i.e. editing a document) or the View’s presentation of the Model (i.e. scrolling through a document). The View The View creates the HTML code that is displayed in the browser by receiving the data from the Controller. The View’s function is to focus on formatting and style, and it’s common to see the code being a mixture of HTML and Ruby.


GDAL supports reading and writing ASCII gridded XYZ raster datasets (i.e. ungridded XYZ, LIDAR XYZ etc. must be opened by other means. See the documentation of the gdal_grid utility).
Those datasets are ASCII files with (at least) 3 columns, each line containing the X and Y coordinates of the center of the cell and the value of the cell.
The spacing between each cell must be constant and no missing value is supported. Cells with same Y coordinates must be placed on consecutive lines. For a same Y coordinate value, the lines in the dataset must be organized by increasing X values. The value of the Y coordinate can increase or decrease however. The supported column separators are space, comma, semicolon and tabulations.
The driver tries to autodetect an header line and will look for 'x', 'lon' or 'east' names to detect the index of the X column, 'y', 'lat' or 'north' for the Y column and 'z', 'alt' or 'height' for the Z column. If no header is present or one of the column could not be identified in the header, the X, Y and Z columns (in that order) are assumed to be the first 3 columns of each line.
The opening of a big dataset can be slow as the driver must scan the whole file to determine the dataset size and spatial resolution. The driver will autodetect the data type among Byte, Int16, Int32 or Float32.

Since we are building this project for a client, we want to make sure we are shipping a high-quality product. In this milestone we will learn how to make sure the RESTful API works properly by using unit testing.
Learn the basics of unit testing that allows you to build new code (tests) that checks that your API works as expected.
https://martinfowler.com/bliki/UnitTest.html
Let’s review some of the ES6 basics (at least “Promise”, “Block scope”, “Arrow functions” sections) and the basics of unit testing using these katas.
http://es6katas.org/
Npm install mocha (test runner) and chai (test assertion library), for JavaScript testing.
https://mochajs.org/
Familiarize yourself with the syntax of BDD unit testing with expect.
http://chaijs.com/api/bdd/
Learn the basics of how to test your Node API.
https://scotch.io/tutorials/test-a-node-restful-api-with-mocha-and-chai
Your package.json should be configured to run the tests from npm run test
Install chai-http in order to facilitate HTTP API testing. https://github.com/chaijs/chai-http
You should implement a test for the endpoint that returns all the events
You should implement a test for the endpoint that returns one event by its id
You should implement a test for the endpoint that creates an event
You should implement a test for the endpoint that updates an existing event (Remember that comparing dates is not easy!)
You should implement a test for the endpoint that deletes an existing event.

I've come to talk with you again
Because a vision softly creeping
Left its seeds while I was sleeping
And the vision that was planted in my brain
Still remains

PUTENV
Section: Linux Programmer's Manual (3)
Updated: 2014-08-19
Index
Return to Main Contents
NAME
putenv - change or add an environment variable
SYNOPSIS
#include <stdlib.h>
int putenv(char *string);
Feature Test Macro Requirements for glibc (see
feature_test_macros(7)):
putenv():
_SVID_SOURCE || _XOPEN_SOURCE
DESCRIPTION
The
putenv()
function adds or changes the value of environment
variables.
The argument string is of the form name=value.
If name does not already exist in the environment, then
string is added to the environment.
If name does exist,
then the value of name in the environment is changed to
value.
The string pointed to by string becomes part of the environment,
so altering the string changes the environment.
RETURN VALUE
The
putenv()
function returns zero on success,
or nonzero if an error occurs.
In the event of an error,
errno
is set to indicate the cause.
ERRORS
- ENOMEM
-
Insufficient space to allocate new environment.
CONFORMING TO
SVr4, POSIX.1-2001, 4.3BSD.
NOTES
The
putenv()
function is not required to be reentrant, and the
one in glibc 2.0 is not, but the glibc 2.1 version is.
Since version 2.1.2, the glibc implementation conforms to SUSv2:
the pointer string given to
putenv()
is used.
In particular, this string becomes part of the environment;
changing it later will change the environment.
(Thus, it is an error is to call
putenv()
with an automatic variable
as the argument, then return from the calling function while string
is still part of the environment.)
However, glibc versions 2.0 to 2.1.1 differ: a copy of the string is used.
On the one hand this causes a memory leak, and on the other hand
it violates SUSv2.
The 4.4BSD version, like glibc 2.0, uses a copy.
SUSv2 removes the const from the prototype, and so does glibc 2.1.3.

Viper
Tips
- If you're trading hits frequently in lane, focus your points in Corrosive Skin rather than your orb.
Corrosive actually deals more DoT (40/60/80/100) than Poison Attack (20/32/44/56).
Counters
- For the first 25 minutes of the game you're not going to get away from Viper and you're not going to win
a manfight against him. Shrug your shoulders, pack your bags up, and start TPing as soon as the first
orb hits you.
- If you're running away from a Viper, you may want to avoid taking potshots at him or casting any spells on
him. Remember that damaging him will put the Corrosive Skin debuff on you, which is a 25% slow when maxed.
- You want to avoid putting DoTs on Viper. Every time he takes damage, Corrosive Skin will refresh on your
hero if you're in 1400 range. Seeing as how Corrosive Skin is also giving him magic resistance, he'll
typically take less damage than you from any DoT.
- THIS INCLUDES RADIANCE. OH GOD NEVER BUILD A RADIANCE AGAINST VIPER.
- Rubick is guaranteed to always steal Viper's ult.

Connect 365 Documentation¶
Indices and tables¶
Overview:¶
Many students have trouble aligning their schedule with friends and finding the time to hang out. Determining the availability of your friends is even more difficult with larger groups, as you would have to either view all their schedules individually or message everyone in a group chat (which can be a hassle to do).
The objective of our web application is to solve scheduling issues among friends, and allow one to easily access a friend’s availability at any given time.
Live Website: https://connect-365.herokuapp.com
Getting Started¶
To setup a localhost web server for developmental purposes, install Python 3.6 with pip.
Next, install the required packages in terminal

Video: Brilliant Dele Alli flick keeps Tottenham move alive as Lucas Moura doubles lead
by Ron CarneTottenham took a 2-0 lead into the half-time interval at West Ham on Saturday with Lucas Moura putting them in control just before the break.
Heung-Min Son had given the visitors the lead over the Hammers after a relatively cagey opening to the encounter, but Spurs began to take control.
SEE MORE: Video: Son scores first goal of Mourinho era for Tottenham vs West Ham
After a brief break in play following an injury issue for West Ham defender Angelo Ogbonna who was wiped out by his own goalkeeper, Tottenham were more alert than their rivals as they broke in attack quickly.
However, they’ll owe a big debt of gratitude to Dele Alli for keeping the move alive as he found himself on the ground on the touchline, but somehow managed to flick it into Son’s path to keep them moving forward, as seen in the video below.
The Spurs forward then put in a brilliant cross to give Moura a chance at a relatively simple finish, and the Brazilian obliged to beat Roberto and put Jose Mourinho’s side in a commanding position to pick up all three points in his first game in charge.


| DOSE: |
500 mg |
insufflated |
Ketamine |
(powder / crystals) |
I had been experimenting with Ketamine at a recreational level for the last 6 months or so, mostly at parties and in nightclubs, enjoying the unpredictable 'bouncy' effects.
There was roughly 500mg left from previous night out, and I was feeling slightly anxious and paranoid about keeping drugs in my parents house. I was very relaxed (but slightly bored) in my room at around midnight, so thought it'd be a good idea to get rid of any incriminating evidence and cure my boredom both at the same time.
I got into bed, turned off the lights, put my headphones on and started listening to music, then insufflated the entire 500mg+ dose at once.
[Erowid Note: 500 mgs of Ketamine is considered an extremely high dose, see Ketamine Dose Chart] I had taken doeses as high as this before, but had just resulted in a sort of blacked out 'sleep' state.
I sat up in bed on my laptop, going through the familiar and enjoyable 'rolling' symptoms - numb lips/blurred vision/heavy head/fidgety hands etc. When I began to hear a steadily rising roaring noise - like the sound of jet plane taking off right outside my window. I turned behind me to look what the cause of this noise was, and to my surprise there was golden light streaming through my blinds.
This was the first time I'd had a completely convincing hallucination on any sort of drug, and was impressed with the level of detail my mind had conjoured up - I could even see tiny particles of dust floating in this sunlight that was shining into my bedroom, even though it was midnight and pitch black outside. I was aware of this fact, and was still very aware of my surroundings too. I was being my usual cynical self about the whole situation - trying to enjoy myself but stay in control at the same time.
I re-adjusted myself in bed, and suddenly felt that jolt of fear that I can only associate with tipping too far back on a chair.
I felt as if I was perched on an imaginary cliff edge - and by leaning to my left side I could 'tip' (quite nervously) over this edge and really feel a true sense of gravity that was pulling me down. I giggled to myself as I tipped backwards and forwards. My head was very very heavy now. Things were starting to get more and more hazy. Once I understood I was in control of this tipping motion, I remember having the rational thought of where this was going to lead, but the voice in the back of my head was fading, and at that moment I honestly didn't care.
I flung myself off the cliff. Not physically but in my mind - and plunged into a bottomless pit of darkness in total freefall.
I fell for what seemed like forever until I began to orientate myself, working out which way was up and which way was down in this apparent infinity. And again understanding that I was in control of the trip, and I could fly around in this darkness, enjoying the thrill of weightlessness and eventually flying all the way up to the stars, looking down on Earth.
The series of events is a little jumbled in my head, but at this point the 'vision' inside my mind and my actual sight began to melt together, as my laptop that was sitting on my lap began to float down through the darkness, until it was focused and in view. I heard snatchings of the music that was playing in my headphones that had been all but silent until now echoing out into the distance (with Pariah // Orpheus in particular ringing very true)
I was regaining my sense of co-ordination, as if the effects were wearing off, which dissapointed my slightly as I wanted more, but I carried on nevertheless. And once I realised I actually possessed a pair of hands again, I instinctively reached for the trackpad of my laptop and navigated the mouse to the top right hand corner where I clicked the red 'X' to close the window and turn the screen black (somehow I knew by doing this I accepted that I was moving on to the next 'layer' of the trip.)
I then felt as if I was lifted off my bed, not by my own control this time, and was suddenly projected straight through my laptop screen at tremendous speed, back into the dark space again, where I was now joined by three girls. Two to my left and one to my right, in white dresses with dark hair, all on horseback (for some unknown reason.)
And I remember that the girl immediately to my left was the most beautiful girl I had ever seen - she was so perfect, I cannot even describe her.
She looked like an angel or something - her dark brown eyes stared deep into me, almost lovingly, but somehow I knew she didn't love me. But it didn't matter because I knew what we needed to do. We were all riding together, but again I wasn't in control. It felt like we were strapped onto rollercoaster tracks, chugging along in slow motion to some sort of destination, with incredible colourful visuals shooting past at high speed. And with movement, sound and light all fusing together as one, my mind unable to seperate the energy that was steadily building up.
It started to become more clear. We were on a mission to prevent the end of the world before 'time' ran out - I say time in inverted commas because I had no concept of it even existing.
I was just there in the moment. But I had some type of countdown, like a bomb timer.
And then i saw it... The Sun. Right infront of me, so beautiful. It was perfectly crisp and clear, like High Definition TV.
I've never seen anything so clear in my life. It was so real (even more 'real' than anything I'd seen before with my own two eyes).
And I could feel the heat radiating off it, comforting me. We galloped towards it on these horses, that gave off a trail of gold light exactly the same that originally came through my blinds,until eventually we were within reaching distance. So I extended my hand out and 'pierced' the surface - and at that same time the countdown timer hit zero.
And every other bit of sound, light and feeling all reached this exact moment of singularity... an absolute peak of nothingness.
That was the turning point... it was like an atomic bomb going off inside my head.
Everything was obliterated outwards in a huge explosion of white light - sight, sound, movement, everything. Was this death? I wasn't sure.
I felt like I had just smashed through a giant invisible pane of glass and I could feel the intense force of my counciousness shattering. It stripped me of every emotion I'd ever felt in my life - especially gulit. I felt completely free, and not even human, I was just a single object blissfully floating through space, all the time believing that this was truly real.
There was no more rational thought anymore, no more perspective or objective view on anything. I felt as if all these barriers had been broken down and for the first time I could 'see' in the truest sense of the word. Looking back now, if the explosive moment before it had been 'death' then now I was 'passing over' to the other side.
I could hear a thousand voices talking to me at the same time, creating an intense yet soothing buzz, almost like a meditating hum, and at the same time see millions of complicated equations whizzing around me. My brain easily seperating and processing this huge stream of information (for what felt like years!).
Although I couldn't decipher any of it to actually read or hear it - I completely understood and agreed with it, however I couldn't recall any of it to you now.
I'm not quite sure how I know this, but I am certain that this was a totally inward experience inside my own subconscious. I was exploring myself as a person, and the drug was the key to my mind that unlocked this whole other level of communication.
I wish I could tell you now all the amazing things I heard.. but there are no words to translate it to you.
Some time after that, the three girls from the previous 'layer' of the trip pulled me down gently from this outer stratosphere, and I floated down like a feather slowly into their comforting arms, where I was now flat on my back looking up at the stars, and we began to fly again. But this time I wasn't in control, I was being carried by them. We were getting faster and faster - faster than i'd ever travelled before, but I felt totally safe. I knew I was going home.
I didn't want it to end, but at the same time I felt ready, and enlightened.
I saw Earth, and we flew down towards it, getting closer. Flying over hundreds of rooftops until they delivered me, back through my bedroom window where I snapped back very suddenly into my body, regaining full conciousness and senses within a split second - I was totally back to normal.
I stayed still for a moment. Contemplating my profound experience in sheer awe, and had to touch my hands and face to check this was reality. I had not moved a single muscle from the seated position I had started in, and to my surprise only 40 minutes had passed!
It had honestly felt like a lifetime. I had a small drink of orange juice to wash away the unpleasant yet familiar taste in my mouth, and felt a lovely warm afterglow from my experience. I remember sitting in bed, beaming from ear to ear that I had the oppurtunity of experiencing something so special, before drifting off nicely to sleep, feeling very happy and fulfilled.
For weeks and months afterwards with an experience such as this I felt the need to share it with people, but nobody really understood. Even my 'drug' friends were sceptical of my sudden spiritual ramblings.
People were trying to laugh this off and tell me that it was just a funny little trip where I danced about in rainbows with unicorns in that sort of stereotypical 'acid' image, but I feel like this was much much more than that. It's given me a different outlook on life, as if all my thoughts had been collected and neatly organised. There were less niggling questions in the back of my mind, less worries, now feeling like I had a much clearer path in life.
I soon began to read up on similar sort of experiences with Ketamine and other substances such as DMT and was shocked to find that nearly every description was the same: flying through space/meeting spiritual other-worldly beings/ego death/moments of singularity...
How could it be possible that the human brain (being as complex and uniqiue in itself) produce such similar experiences in individual people when administered with a drug?
Such small details re-appearing throughout these accounts make me sometimes beleive that this is more than just a coincidence - and that actually we are unlocking some deep hidden part of our subconcious that isn't accessable to the sober mind.
And all this time, it genuinely astounds me that the brain has the power to do all of this... to make us see/hear/feel such wonderful things, and yet for 99% of the time we cannot access it? we need so-called 'illegal substances' to reach the full potentials of our minds.

Dat Protocol
DEP-0010: Hypercore Wire Protocol
Title: DEP-0010: Hypercore Wire Protocol
Short Name: 0010-wire-protocol
Type: Standard
Status: Draft (as of 2019-02-27)
Github PR: Draft
Authors: Paul Frazee, Bryan Newbold
Summary
This DEP describes the Hypercore wire protocol: a transport-agnostic message stream spoken between nodes in a swarm of hypercore network peers (including Dat clients). The wire protocol includes mechanisms for framing, stream encryption, and feed key authentication.
Motivation
The protocol described here is already in use as of 2017 (by Hypercore, Dat, and Beaker Browser users), and was partially described in an earlier whitepaper. This document fills in some additional details.
Stream Connections
The Dat wire protocol depends on the use of a binary transport protocol which provides the following semantics:
- reliable delivery (no dropped or partial messages)
- in-order delivery of messages
Two notable transport protocols that satisfy these requirements are TCP and µTP (the "Micro Transport Protocol").
Peers wishing to connect need to discover each other using some mechanism or another (see forthcoming DEPs on some options; this process is modular and swappable), and both need to have the public key for the primary hypercore they wish to exchange.
Messages are framed by the Dat protocol itself (see Messages section for details).
Channels
Multiple hypercore feeds can be synchronized over the same protocol connection. Messages pertaining to the separate channels are tagged with an id for disambiguation.
Note that at least one feed is necessary for each connection (for handshaking to succeed), and that the first feed is the one used for discovery and as an encryption key.
To initiate a new channel (after the primary is established), a peer can send a Feed message, followed by an Info message. Unlike the first message sent on an overall connection, later Feed messages are encrypted. Either party may initiate a new channel with a Feed message at any time.
Handshake Procedure
A handshake procedure needs to occur for each feed on a channel; the first part of the first handshake happens in cleartext and both validates discovery keys and establishes encryption parameters used for the rest of the connection. The first (primary) channel has id=0
.
The first (cleartext) message is a Feed message, and includes two fields: a nonce and a discovery key.
The nonce is generated by each peer as a random 32-byte sequence.
The discovery key is generated from the public encryption key for a hypercore feed (in this case the first, or "primary" feed) by using the public key to perform a keyed hash of the 9-byte ASCII string "HYPERCORE" (with no trailing NULL byte) using the BLAKE2b keyed hashing algorithm (provided by most BLAKE2b hash implementations). The discovery key is 32 bytes long.
Example of generating a discovery key in pseudo-code:
discoveryKey = BLAKE2b(message = 'HYPERCORE', key = publicKey, outputLengthBytes = 32)
The discovery key is used in cleartext instead of the public key to avoid leaking the public key to the network; read access to hypercore feeds (including Dat archives) is controlled by limiting access to public keys.
When the connection is first opened, the connecting peer sends their Feed message. The receiving peer checks that the discovery key was expected (eg, that they know of a public key matching that discovery key and are willing to synchronize the feed associated with that key). If so, they reply with their own Feed message. If not, they drop the connection.
Once Feed messages are exchanged, both peers have all information they need to encrypt all further content on the channel, and do so (see below for details). The second part of the handshake is to exchange Handshake messages, which set some parameters for the channel. Handshakes also include the self-identified peer id, which can be used to detect accidental self-connections or redundant connections to the same peer (eg, over different transports). The peer id is typically random and is not authenticated.
Encryption Scheme
After the first Feed messages are exchanged (one message in each direction, in cleartext), all further bytes exchanged over the channel are encrypted.
Framing metadata (aka, message length and type) is encrypted, but a third party could likely infer message lengths (and thus potentially message types) by observing packet sizes and timing; no padding is applied at the protocol layer.
The encryption scheme used is libsodium's stream primitive, specifically the XSalsa20 cipher. The cipher is fed a shared key (the primary hypercore feed public key), a nonce (selected by the sender and exchanged during handshake), and a block offset (representing all encrypted bytes sent on the connection in this direction so far).
The specific libsodium function used is crypto_stream_xsalsa20_xor_ic()
. Some interfacing code is necessary to process messages that don't align with the cipher's 64-byte chunk size; unused bytes in any particular chunk can be ignored (or, as an optimization, cached for use with the next message). For example, if 1000 encrypted bytes had been sent on a connection already, and then a new 50 byte message needed to be encrypted and sent, then one would offset the message by 1000 % 64 = 40
bytes and XOR the first 24 bytes against block 15, then XOR the remaining 26 bytes against block 16. The bytes would be shifted back and recombined before sending, so only 50 bytes would go down the connection; the same process would be followed by the receiver.
Want/Have Procedure
The wire protocol is designed to be efficient when syncing extremely large Hypercore feeds (ie millions of blocks in length). Therefore a procedure exists for each peer to indicate which subset of the feed they would like to synchronize, and for the remote to then announce which blocks within those subsets they possess. This is the Want/Have Procedure.
By default, a peer wants no blocks. It can add or remove wanted block using the Want and Unwant messages.
When new wanted blocks are made available, the peer should react by sending a Have message. Likewise, when wanted blocks are no longer available, the peer should react by sending an Unhave message. Finally, any time a Want message is received, the peer should react by sending a Have message.
Request Procedure
After the Want/Have Procedure, a peer will know what Hypercore feed blocks are available on the remote, and can then send Request messages for the individual blocks. Each Request specifies which block it needs, and also specifies some information about Merkle tree proof nodes which should be included. In reaction, the remote sends a Data message with the requested content.
At present, Request messages can only specify one block at a time. This is to encourage an equal distribution of requests between multiple connected peers. However, multiple requests can be sent in parallel.
Extension Procedure
To allow for experimentation within userland, the wire protocol supports an extension process. All extensions are identified by strings, and sent in an array in the Handshake message. Both peers must declare an extension in the handshake to consider it 'supported'.
Each extension is capable of sending custom payloads through the Extension message type.
Message Details
The connection between peers is an endless stream of bytes, so each message must be "framed" so the recipient knows when it starts and ends. The wire framing format is <len>(<header><message>)
. len
is a varint with the number of bytes in the following message (the sum of the header
and message
). header
is a varint, of form channel << 4 | <4-bit-type>
. Note that in most cases the header
varint will be a single byte, but clients should treat it as a varint to accommodate large channel counts.
Messages are encoded (serialized) using Google's protobuf encoding.
type code | Name |
|---|---|
| N/A | Keep-Alive |
| 0 | Feed |
| 1 | Handshake |
| 2 | Info |
| 3 | Have |
| 4 | Unhave |
| 5 | Want |
| 6 | Unwant |
| 7 | Request |
| 8 | Cancel |
| 9 | Data |
| 15 | Extension |
Keep-Alive
A message of body length 0 (giving a total message size of 1 byte for the len
varint) is a keep-alive. Peers must always handle keep-alive messages correctly (aka, ignore them), regardless of transport.
Depending on transport and application needs, peers may optionally send keep-alive messages to help detect and prevent connection loss. Implementors are free to chose their own period or strategy for sending keep-alives. A reasonable default period is 300 seconds (5 minutes).
Feed
type=0
Should be the first message sent on a channel. Establishes the content which will be exchanged on the channel. See the Channels section for details.
message Feed {
required bytes discoveryKey = 1;
optional bytes nonce = 2;
}
Handshake
type=1
Overall connection handshake. Should be sent just after the Feed message on the first channel only.
Some notes on the fields:
- id Typically a 32-byte identifier which is allocated randomly by a peer at the start of its swarming session. Not authenticated. Used to help detect multiple connections to a single peer.
- live If both peers set to true, the connection will be kept open indefinitely.
- userData An open field for sending data which you can retrieve on handshake. No value is prescribed by the protocol.
- extentions A list of strings identifying additional message-types which are supported via the Extension message.
- ack A peer (the "sender") can set this flag to request that every time another peer (a "receiver") gets a
Data
message from the sender, that they reply with an explicitHave
message once they have successfully persisted the data in storage. This lets the "sender" track how many persisted copies of a chunk there are.
message Handshake {
optional bytes id = 1;
optional bool live = 2;
optional bytes userData = 3;
repeated string extensions = 4;
optional bool ack = 5;
}
Info
type=2
Indicates state changes in a channel. The initial state for uploading & downloading is true
. If both ends are not downloading and not live, it is safe to consider the channel ended.
message Info {
optional bool uploading = 1;
optional bool downloading = 2;
}
Have
type=3
Announces the availability of Hypercore feed blocks for download. If no bitfield
is present, the start
and length
represent a continuous set of blocks. If bitfield
is present, it will convey the availability of individual blocks, offset from the start
. For information about the encoding of bitfield
, see "Run-Length Encoded Bitfield" below.
The Have message is sent in the following contexts:
- In response to a Want message.
- To announce new blocks which have been added within a remote-wanted range.
message Have {
required uint64 start = 1;
optional uint64 length = 2 [default = 1]; // defaults to 1
optional bytes bitfield = 3;
}
Unhave
type=4
Announces the loss of availability of Hypercore feed blocks for download. The start
and length
represent a continuous set of blocks.
This message is sent in the following contexts:
- To inform the peer that data which was sent was rejected, for instance because it was not requested and pushes are not being allowed.
- To announce blocks have been removed from local storage within a remote-wanted range.
message Unhave {
required uint64 start = 1;
optional uint64 length = 2 [default = 1]; // defaults to 1
}
Want
type=5
Announces a range of Hypercore feed blocks which the peer would like to receive Have/Unhave messages about. Remote should respond with a Have message which describes which of the wanted blocks are available, and should send additional Have/Unhave messages if availability within the wanted range changes.
message Want {
required uint64 start = 1;
optional uint64 length = 2; // defaults to Infinity or feed.length (if not live)
}
Unwant
type=6
Announces a range of Hypercore feed blocks which the peer would no longer like to receive Have/Unhave messages about.
message Unwant {
required uint64 start = 1;
optional uint64 length = 2; // defaults to Infinity or feed.length (if not live)
}
Request
type=7
Request data from the remote. The remote should be react by sending a Data message.
The fields are as follows:
- index The Hypercore feed block being requested.
- bytes An alternative to
index
, a byte offset into the Hypercore feed. Instructs the remote to send the block at the givenbytes
offset. - hash If true, only send the nodes, not the block data.
- nodes Communicates which parent and uncle nodes should be included in the Data response. See "Block Tree Digest" (below) for an explanation of the encoding.
message Request {
required uint64 index = 1;
optional uint64 bytes = 2;
optional bool hash = 3;
optional uint64 nodes = 4;
}
Cancel
type=8
Cancel a Request message sent earlier. The remote should react by aborting any active or queued Request message which matches the index
, bytes
, and hash
parameters.
message Cancel {
required uint64 index = 1;
optional uint64 bytes = 2;
optional bool hash = 3;
}
Data
type=9
Send a Hypercore feed block. May contain the data of the block, and may contain the hashes of the ancestor nodes in the merkle tree. Should only be sent in reaction to a Request message.
When a Data message is received, its node hashes and signature should be verified against any local tree information. If the nodes can be verified, they and the block data may be stored locally.
If a Data message is received for a block which was not requested, the peer can react by ignoring the data and sending an Unhave message in response. This will inform the remote that the data was rejected, and is not stored.
message Data {
message Node {
required uint64 index = 1;
required bytes hash = 2;
required uint64 size = 3;
}
required uint64 index = 1;
optional bytes value = 2;
repeated Node nodes = 3;
optional bytes signature = 4;
}
Extension
type=15
Send a custom message.
The user-type
is an index into the extensions
array sent in the Handshake. For instance, if two extensions were declared ['foo', 'bar']
then the user-type
of 'foo'
would be 0
and of 'bar'
would be 1
.
The payload
may be any message content, as needed by the extension.
<varint user-type><payload>
Run-Length Encoded Bitfield
The Run-Length Encoded (RLE) bitfield is a series of compressed and uncompressed bit sequences.All sequences start with a header that is a varint. If the last bit is set in the varint (it is an odd number) then a header represents a compressed bit sequence. If the last bit is not set then a header represents an non compressed sequence.
compressed-sequence = varint(byte-length-of-sequence << 2 | bit << 1 | 1)
uncompressed-sequence = varint(byte-length-of-bitfield << 1 | 0) + bitfield
Block Tree Digest
As described in DEP-0002 (Hypercore), a peer should be able to verify both the integrity of received data (aka, was there corruption somewhere along the way, detected via hash) and the authenticity (aka, is this the data from the original writer, detected via signature). Hypercore transmits the hash for every data block, but only signatures for the root hashes of Merkle trees, not individual block hashes, which means a peer may need additional hashes (for data blocks they do not have a copy of) if they want to verify the signatures of individual blocks.
Redundantly transmitting all such hashes on every request would be inefficient if the receiver already had some hashes, so requesting peers can specify which hashes they need in the nodes
field of the Request
message. Instead of sending an array of node indexes, the nodes
field is a compact bitfield (serialized as a uint64
), indicating for each "uncle" and "parent" whether the hash should be transmitted.
Consider the following tree:
0
1
2
3
4
5
6
If the receiving peers wants to fetch, and verify, block 6, it needs to communicate whether it already has the uncle hashes (4, 1) and the parent hashes (3). This information can be compressed into a small bit vector with the following scheme:
- the least-significant bit indicates whether the most-significant bit is a "parent" (if '1') or an "uncle" (if '0')
- all other bits, in order from least- to most-significant, indicate whether the corresponding "uncle" hash does need to be transmitted (if bit '0') or does not (if bit '1')
As an example, suppose we want to fetch block 6 from a remote peer, and we already have the sparse node metadata (hashes) for blocks 3 and 4, but not 1. In other words:
- 4, an uncle, we already have the hash
- 1, next uncle, we don't have hash
- 3, a parent (and root hash), we do have hash
- root signature (of hash 3) will be sent with request
Our Request
should have the following nodes
bitfield (0b1011
encoded in the least-significant bits of a uint64
):
1011
│││└── indicates that the most-significant bit is a parent, not an uncle
││└─── do not send hash for the first uncle, 4
│└──── do send hash for the next uncle, 1
└───── do not send hash for next parent, 3
Using the index
field of the Request
message, the receiving peer can calculate the number of packed bits and extract the bitfield. The "most-significant bit" referenced above is of just the fixed-size bitfield, not the uint64
as a whole.
From this, the remote peer will know to only send one hash (for block 1) for us to verify block 6. Note that we (the receiver) can calculate the hash for block 6 ourselves when we receive it.
As a special case, the bit vector 1
(only contains a single one) means that the sender should not send any hashes at all.
These digests are very compact in size. Only (log2(number-of-blocks) + 2) / 8
bytes are needed in the worst case. For example if you are sharing one trillion blocks of data the digest would be (log2(1000000000000) + 2) / 8 ~= 6
bytes long (which fits in a single uint64
). This scheme works for Hypercores with up to 2^62 = 4,611,686,018,427,387,904
blocks.
Examples
Simple Download
Alice has an e-book identified by a public-key (PK) which Bob would like to download. The e-book also has a discovery-key (DK). Bob connects to Alice, and the following exchange occurs:
BOB: sends Feed (unencrypted) {discoveryKey: DK, nonce: BobNonce}
BOB: sends Handshake {id: BobID}
ALICE: sends Feed (unencrypted) {discoveryKey: DK, nonce: AliceNonce}
ALICE: sends Handshake {id: AliceID}
BOB: waits for Feed
BOB: waits for Handshake
ALICE: waits for Feed
ALICE: waits for Handshake
BOB: sends Want {start: 0}
ALICE: receives Want {start: 0}
ALICE: sends Have {start: 0, bitfield: ...}
BOB: receives Have {start: 0, bitfield: ...}
BOB: sends Request (for block 0)
ALICE: receives Request (for block 0)
ALICE: sends Data (for block 0)
BOB: receives Data (for block 0)
BOB: sends Request (for block 1)
ALICE: receives Request (for block 1)
ALICE: sends Data (for block 1)
... (repeat for all other blocks) ...
BOB: sends Info {downloading: false}
ALICE: closes connection
Privacy and Security Considerations
All security and privacy guarantees of this protocol implicitly depend on the soundness of the underlying cryptographic primitives, algorithms, and implementations, which include BLAKE2b and XSalsa20.
A connecting peer, or any observer able to decrypt traffic, may be able to infer the following from protocol traffic:
- what subset of content the local peer already has access to (via Have message)
- what subset of content the local peer is interested in (via Want and Request messages)
A "persistent" (all-seeing) observer can infer the following with reasonable confidence, using only protocol traffic:
- which peers (identified by IP address, timing, topology, or other network metadata) have connected which other peers
- the relative flow of content (which peer provided data to the other, and how much)
- which primary hypercore feeds which peers have knowledge of (identified by discovery key, not public key)
- which peers have the public key for a given discovery key (based on whether connections succeed)
Such an observer can not determine the specific content of hypercore feeds, or (with confidence) which peer (or peers) have write access to a feed.
The wire protocol does not pad message sizes. This means that a persistent observer could potentially identify traffic content by inferring message sizes.
The hypercore protocol does not intentionally identify peers across connections, but it has been shown in other network protocols (like HTTP) that even the smallest amount of identifying metadata can be used, statistically, to track and surveil users. These techniques are sometimes called "device fingerprints", "browser fingerprints", or "permacookies". Hypercore protocol users should not consider themselves immune to such tracking without specific additional effort to identify and mitigate such fingerprints.
Any network observer with the public key can fully decrypt the network traffic of any and all peers establishing a connection using that key. This includes channel content other than the first (discovery) channel. Peers should not consider extension messages, "Have"/"Want" metadata, or any other messages or metadata private from other peers (or observers) with the public key.
The wire protocol encryption provides message secrecy (from parties who do not have the public key), but does not guarantee any form of authenticity. In the case of Dat and hypercore, the application layer itself verifies authenticity of transferred content using hashes and signatures. However, implementors should note that network agents who can manipulate traffic can modify data in flight without detection, regardless of whether they have the feed public key. However, peers are already not trusted parties, and thus implementors must already take care to treat protocol messages as potentially hostile input.
The issues of observer decryption and message authenticity may be addressed in a future revision of the wire protocol.

Unresolved questions
- Encryption might not make sense in some contexts (eg, IPC, or if the transport layer is already providing encryption). Should this DEP recognize this explicitly? Does not need to be addressed before Draft status.
- There is a potential race condition with channel index numbers. If each peer sends a new Feed message on a new channel at the same time (aka, before the remote message is received), what should peers do? Probably ignore the channel and try again. Possibly channel indices should go even/odd depending on the peer proposing to prevent conflicts. Does not need to be resolved before Draft status.

Missouri Man United with Seven Siblings After 50 Years | Breitbart
A 63-year-old Missouri man realized he had become a half brother to seven different siblings 51 years later after he took a DNA test using ancestry.com.
by Katherine RodriguezJimmy Seville, 63, initially knew he had a different dad growing up and sought to find him when he was old enough.
“Twelve years old I knew I had a different dad,” Seville told WDAF. “And then my goal was when I got old enough that I would seek out this person.”
He thought he found his dad in 1995, but he turned out to be wrong.
“And turned out he wasn’t my dad,” Seville said. “So I kinda gave up, and I start back looking.”
In September 2019, Seville took a DNA test with ancestry.com when the name “Dylan Decker” came up.
“Mom says I need to tell you something,” Seville recalled his mother telling him in October. “She pulls out a manila envelope and in that envelope is a picture of a gentleman in a Navy uniform. Young, good-looking, and she says ‘this is your dad.’”
Seville said he was irked by his mother’s decision to hide this information from her, but he decided to remain cordial with her.
Seville also learned that his dad was dead shortly after finding out about his existence.
“The obituary kinda threw me because usually they put all your siblings and connections and everything and nothing was there,” Seville said.
Seville’s curiosity brought him to Facebook, where he typed in several names in connection with his late father. A Facebook conversation between one of the brothers, Donald Decker, led to their meeting in person on November 15.
“I knew right off the bat that he was my brother,” Donald Decker said. “His eyes were just like my father’s, his hands had the same hairline.”
Seville said he plans to meet with his reunited family members more often.


collector
unglazed
Path: CARNOT/Source/Solar_Thermal
Purpose
Model
for unglazed solar thermal collectors including condensation effects for
temperatures below dewpoint.
Description
The collector model is a
2 x N multinode model for thermal
collectors. The model is based on parameters obtained from measurement, i.e.
collector-test results. The energy balance for every node
is a differential equation, that is calculated in the
S-function
solarcollector_unglazed.
For the absorber the energy balance is:
c_abs * dTp/dt = qdot_solar - qdot_conv
- qdot_cond - qdot_sky - qdot_fluid
qdot_solar = absorbed_solar_radiation - uc1_eta0*Iglb*vwind
qdot_conv = qdot_conv_gain + qdot_conv_loss
qdot_conv_gain = fconv * (Uc0_gain +
Uc1_gain * vwind)
* (Tplast + fconv * (Tp - Tplast) - Tamb)
qdot_conv_loss = (1 - fconv) * (Uc0_loss +
Uc1_loss * vwind)
* (Tpo + fconv * (Tp - Tpo) - Tamb)
qdot_cond = fcond * (Uc0_cond + Uc1_cond *
vwind) * Ccond
* (ps(Tdew) - ps(Tp_cond))
qdot_sky = epsilon * sigma * (Tp^4 - Tsky^4)
qdot_fluid = hi * (Tp - Tf)
where :
fconv = ( min( Tpo , max(Tamb,Tplast) ) - Tplast ) / ( Tpo - Tplast )
fcond = ( min( Tpo , max(Tdew,Tplast) ) - Tplast ) / (
Tpo - Tplast )
Tp_cond = Tplast + fcond * ( Tp - Tplast )
Tpo = 2*Tp - Tplast
The fluid's node is devided into "NODES"
nodes.
The energy-balance for every node is a differential equation:
c_fluid * dTf/dt = hi * (Tp - Tf)
+ mdot * cp / Acoll * (Tlastnode - Tnode)
| Symbol | used for | unit |
| Acoll | absorber surface area | m² |
| Ccond | coefficient for pression in temperature conversion | K/Pa |
| cp | heat capacity of fluid | J/(kg*K) |
| c_abs | heat capacity of absorber per surface | J/(m^2*K) |
| c_fluid | heat capacity of fluid per surface | J/(m^2*K) |

| Uc1_loss | wind speed dependant part of the heat transfer coefficientfor the convective losses | W/((m/s)*m^2*K) |
| vwind | wind speed | m/s |
The collector calculates friction losses in the
massflow. This may be specified in the subsystem "pressure drop" of the collector (see
also subsystem "pressure drop of collector" in carnot/heat_source.
Static pressure is calculated if necessary, i.e. for thermosyphon systems.

Bono
Rock star, activist, and philanthropist
As a rock star, I have two instincts, I want to have fun, and I want to change the world. I have a chance to do both." -Bono
Paul David Hewson (born 10 May 1960), known by his stage name Bono, is an Irish singer-songwriter, musician, venture capitalist, businessman, and philanthropist. He is best known as the lead vocalist of rock band U2. Bono was born and raised in Dublin, Ireland, and attended Mount Temple Comprehensive School where he met his future wife, Alison Stewart, and the future members of U2. Bono writes almost all U2 lyrics, frequently using religious, social, and political themes. During U2's early years, his lyrics contributed to their rebellious and spiritual tone. As the band matured, his lyrics became inspired more by personal experiences shared with the other members. Outside the band, he has collaborated and recorded with numerous artists, is managing director and a managing partner of Elevation Partners, and has refurbished and owns the Clarence Hotel in Dublin with The Edge. Bono is also widely known for his activism concerning Africa, for which he co-founded DATA, EDUN, the ONE Campaign and Product Red. He has organised and played in several benefit concerts and has met with influential politicians. Bono has been praised for his activism and involvement with U2. Bono was granted an honorary knighthood by Elizabeth II of the United Kingdom for "his services to the music industry and for his humanitarian work", and has been made a Commandeur of the French Ordre des Arts et des Lettres (Order of Arts and Letters). Together with Bill and Melinda Gates, Bono was named Time Person of the Year in 2005, among other awards and nominations.
