Hal - Version 2.6
What is Hal?
Hal is the deployment system we use to deploy many of our client-facing websites, including MyQL, Rocket Mortgage, QLMS, ORMS, Agent Insight, QuickenLoans.com and more!
New Features
-
Kraken Runtime Configuration has been added.
This is the first release of Kraken, but cannot yet be used in production as the QKS Encryption service is not finished.
What is Kraken?
-
Kraken allows application owners to set runtime configuration. This configuration consists of properties that can be modified and deployed
through the Hal interface, rather than requiring a new code deployment.
- Kraken is available at /kraken and can be enabled on your navigation menu through your settings.
What kind of data can be stored in Kraken?
- Cache servers
- Feature flags to disable parts of application (dark launching)
- Logging settings
- Sensitive configuration that should be encrypted at rest (database passwords, api keys)
Please see the Kraken Help page for more information.
-
Hal now uses a dedicated user authorization system.
Active directory is no longer used for permissions. Permissions are now managed directory within Hal by administrators.
This results in several new features:
- Much faster page load times. Active Directory permission checks slowed down most core pages.
- Any user can be made an Application lead, giving non-administrators access to manage an Application's Properties, Deployments, and Kraken Schema.
- Any user can be given non-prod or prod deployment permissions.
The following user types are available:
- Standard - deployment permissions determined by GHE organization membership.
- Deployment - was granted deployment permissions for a specific application to either non-prod or prod environments.
- Lead - can manage a specific applications settings, deployments, encrypted properties, kraken schema and deploy to non-prod.
- Admin - can manage all applications, and deploy to all environments.
- Hal Admin - can manage all applications, and deploy to non-prod.
Changelog

Veggies 2 U is a local Portland startup which puts focus on fast, friendly delivery of the best organic produce that the Great Northwest has to offer.
It all began in late 2009. Adam had lost his job as a web programmer, the economy was in shambles and his prospects were slim. He needed hope. He didn't know it then, but he needed Veggies (and a spark from Eve).
A friend, on a lark, offerred up his foodtruck to live in while he looked for work. As a former (reformed?) web programmer, he spent all of his time on his computer. Until his Macbook broke. And he was forced to go to the Apple store, where chamce would have it, he met Eve, who changed his life.
Eve had had enough of Apple, and wanted change herself. She called Apple the forbidden fruit, so she jumped at the chance to join Adam in the foodtruck and begin selling that green alternative - Veggies! And thus, Veggies2U was born.
Adam BigBeard is a web-programmer turned veggie entreprenuer. He loves kale chips, long walks on the farm and listening to poetry.
Adam is responsible for making deliveries for Veggies 2 U, and manning the VegVan (it is not a VW diesel!) when parked at community events. It gives him no greater joy than seeing the look on a kid's face when they bite a beet for the first time...and hate it.
Eve TreeClimber spent much of her formative years in that garden of technology, Apple, rising up to be their local blue-shirt leader. She fixed iPhone screens, glued together iPads that kids stepped on and generally kept big Apple churning in Portland.
Eve loves spending time with her dog on the farm, hiking in the mountains with Adam and planning the next crop for Veggies2U.
Eve's favorite veggie is the carrot. It was her high school mascott.


I like the visualisation used in this meditation and found it helpful. I lied the idea of the metal habits the meditation can develop like seeing goodness in self and others and giving goodness to all.
also liked the visualisation aspect of this meditation. I have learnt that I find visualisation to be a helpful tool. I found the previous mediation to have be more beneficial to myself, however I like how the Tonglen is about transformation, and I am willing to come back to it in the future.
The SCARF model is made up of five domains: Status, Certainty, Autonomy, Relatedness and Fairness. During my Phase 0 experience I have found there to be a status reward, when comparing myself to before the start of Phase 0. I know more than when I started.
There has been less certainty at times, especially when I feel blocked, about how well I am progressing and will I have understood enough for bootcamp.
At bootcamp I think the SCARF model will apply more due to the cohort being together in person, and relatedness and fairness will take bigger roles. Bootcamp should hopefully bring more certainty and status also
I think the section about mindful e-mailing was useful and something to be aware of as e-mails are predominately how we communicate in a lot of situations. Miscommunication is common and the five steps are worth taking when writing, especially involving delicate topics.


--- layout: archive title: Zulip Chat Archive permalink: /stream/113489-new-members/topic/mathlib.20tactics.html ---
I have a local copy of the tutorial project. In the first_proofs.lean file, I have access to tactics define in mathlib such as library_search. When I make a new file in the same folder, I don't. Is there a magic incantation I am missing?
Did you "open folder" in vscode?
Hmm I think so; let me close the VSCode instance and try again.
You can tell because the explorer sidebar should show a listing of files in the folder rather than a button saying "open folder"
yes, my sidebar has a listing of folders that includes a bunch of the mathlib source
You should open the tutorial folder, the one with leanpkg.toml
in it
I believe the tutorial files are in a src
directory inside it. If you create another file in the src
directory with extension .lean
, it should work
vscode.png Here's what my VS Code looks like right now, if it helps.
An important "magic incantation" is import tactic
at the top of the file, or some import that will transitively include tactic
.
I have included import tactic and things now work the way I expect them to. Thanks all!
The first_proofs.lean file has import data.real.basic which i guess transitively includes tactic
Yes, essentially any import from mathlib imports a whole lot of tactics (but not all of them).
There are "core" tactics imported automatically (like simp
and rw
), which will get you only so far, and then the community writes other tactics (like ring
or linarith
) which get put into mathlib and which must be imported manually. [it's analogous to groups being in core so being imported automatically, but modules needing a manual import]
I seem to have some but not all of the tactics listed at https://github.com/leanprover-community/mathlib/blob/master/docs/tactics.md
Then things are functioning correctly ;-)
Perhaps that list should explicitly flag which ones are not imported by import tactic
.
I seem to have some but not all of the tactics listed at https://github.com/leanprover-community/mathlib/blob/master/docs/tactics.md
import tactic
should get you essentially all of them. Which are you missing? It's likely they should be there.
i don't have suggest
Perhaps that list should explicitly flag which ones are not imported by
import tactic
. If you typeimport tactic.linarith
you will get a bunch more.
linarith
should be included in import tactic
.
i do have linarith
Yeah, suggest
was added pretty recently and I'm guessing we forgot to add it to the relevant list.
import tactic.suggest
seems to fix it
If you don't have a tactic, you can always search mathlib for it and import the relevant file
the naming is usually pretty obvious though, e.g. tactic.suggest
New users find it hard to search mathlib because by default VS Code doesn't search dependencies
I mean grep for it
New users tend not to be command-line savvy either (at least if they're coming from a maths background)
Or search here: https://leanprover-community.github.io/mathlib_docs/ :slight_smile:
If you have mathlib in the _target
folder, will vscode's file search look in there?
Rob link: Now that does work! We should perhaps advertise this.
I do happen to know how to use grep, but I like rob lewis's answer a lot
I actually mean vscode's file search; I don't actually use grep
If you have mathlib in the
_target
folder, will vscode's file search look in there?
If you have followed all the instructions in the mathlib readme to the letter as a new user, then the answer is no
does it work if you specify it in the "search within" area? (Don't have a lean project to test atm)
and the reason is this: blue.png -- the button "ignore system files in your search" is checked by default
What makes things worse is that the button is also hidden by default
It's not necessarily a bad default - mathlib is big and you should probably only search in it deliberately
How often is mathlib bumped in the tutorial project?
That's also a good question -- a new user might not have suggest
because it's not there ;-)
I guess it's bumped whenever someone bumps it. There's nothing automatic set up. It can't really hurt to do it regularly.
(to confirm kevin's suspicion, import tactic.suggest doesn't do anything for me)
Oh, I checked out Rob's link, and it's a lot better than I last saw
we have a search now!
Yep, Google got around to indexing the doc pages.
I might suggest putting tactic.suggest
as the main header though, it's not obvious what file I'm looking at
or how to import it into my project
looks like it's in the <title> but that's not copyable
The module doc at https://github.com/leanprover-community/mathlib/blob/1c4a2966ef25ec82e65337022a0764e87a81d992/src/tactic/suggest.lean is malformed, which is why it's missing a header. But yeah, the path should probably be formatted as an import somewhere on the page.
If you want these doc pages to really look good, and search to really work, the library needs to be documented correctly!
the header on the sidebar should also have the full path. https://leanprover-community.github.io/mathlib_docs/tactic/rewrite_all/basic.html has header "basic" which isn't so helpful
Yup. I'll change that to be the full import path.
You could put the path in the file header, but that's just going to make the quality dependent on good doc headers, whereas this is something that can be applied uniformly by the doc tool itself
I think it actually looks a bit weird that there is no h1 header in the main pane, it just jumps right into the file header. I'm thinking something like:

tactic.suggest
 file header...
I think it looks pretty natural on files like https://leanprover-community.github.io/mathlib_docs/geometry/manifold/real_instances.html where the file name isn't a great description of the file contents.
I see, you want the file header to actually have an h1 in it. In that case, I would suggest putting the file name as
file.name

above the main header
I'm not sure. I'll add the full path to the right sidebar for sure. Putting it at the top of the page would be duplicating info. It's also visible in the cascading menu on the left, in a slightly different format.
I'll experiment, but it'll have to wait until after lunch.
That's true. I like the Rust docs: https://doc.rust-lang.org/std/convert/trait.AsRef.html . The path is the main header, while the sidebar only contains subfunctions and a short name. The source link is also on the main header (the [src] link)

The first one is certainly relevant, but the others not so much. I would have expected more relevant results...
After all, there are 3 files with "manifold" in their name
@Simon Hudon Didn't you have some method to bump mathlib in projects that depend on it? You were working on something like that recently. Could that be used to keep the tutorial project up to date with mathlib? (Bump it once a month, or once week, or so.)
A google search will try to use pagerank which will be pretty close to useless for us
I actually find the Rust docs a little confusing, but I don't know the Rust ontology, so maybe that's not surprising. I suspect we're tied more closely to our file structure than they are. There doesn't seem to be a version of our collapsible menu in their docs. But this structure is the main method of organization in mathlib right now.
I swapped the sides of the two nav menus, so now the file name appears in full in the top left.
It seems more like a title there than in the top right.
The collapsible menu is a little bare at the top. Maybe the search box should move over there?
Search is using Google's "site search," which is more specific than a generic Google search but much worse than a dedicated search tool. Ideally we'd return results at the declaration level, not at the page level. But we'd have to change the whole hosting setup for that, GitHub Pages only supports static sites.
Oh, the left menu isn't a consistent size anymore. I messed something up swapping the sides. Pretend it's always the same width for now.
i also find the rust docs to be a bit confusing, but that's perhaps just the fact that i'm not used to them.
personally, i've always liked the go docs (e.g. https://godoc.org/github.com/gorilla/websocket), but i'm not sure how well this general style applies to lean.
the current lean docs already look pretty good!
(to confirm kevin's suspicion, import tactic.suggest doesn't do anything for me)
@Jalex Stark If you installed the tutorial project from the command line with something like
git clone https://github.com/leanprover-community/tutorials.git cd tutorials leanpkg configure update-mathlib
then you could go back to the command line, find your way back into the tutorials directory, and this time type
leanpkg upgrade update-mathlib
and you should magically get access to suggest
(although it sounds like you'll have to import it still).
I admit that hierarchical navigation in the Rust docs is not so easy (you can navigate "modules" in the left nav but you have to go through a lot of pages), but the search is good enough that I don't really need it most of the time. The main pages talk about a struct and its functions, but that distinction is less clear for us so having file based navigation seems fine. But a good search (even just within identifiers) is very helpful for getting around
[...] Ideally we'd return results at the declaration level, not at the page level. But we'd have to change the whole hosting setup for that, GitHub Pages only supports static sites.
We could also implement the search part in javascript, this still works using static hosting. IIRC sphinx also uses this approach.
That is my thought as well. I'd volunteer but I don't think I can find the time right now
so I'll just make zero-effort suggestions here :P
This is way out of my wheelhouse too, heh. CSS is bad enough.
lol, you should try to do the search in CSS
surely it's turing complete by now
https://stackoverflow.com/questions/2497146/is-css-turing-complete
But I got annoyed enough trying to make the three columns scroll separately.
To do JS search, we'd have to have the whole declaration database in JS, right? Or is there some way to pre-index it?
To do JS search, we'd have to have the whole declaration database in JS, right? Or is there some way to pre-index it?
I think the usual approach is to store a precomputed index as a separate (e.g. JSON) file that is generated when building the documentation, and then load it on demand.
I looked at how the rust docs do it: At the end of view-source:https://doc.rust-lang.org/core/panicking/index.html there is a script tag going to search-index1.39.0.js which is precomputed during doc generation
It's marked


BLOW
Reviewed by Harvey Karten New Line Cinema Director: Ted Demme Writer: Bruce Porter (book), David McKenna Cast: Johnny Depp, Penelope Cruz, Rachel Griffiths, Ray Liotta, Franka Potente, Paul Reubens, Ethan Suplee, Cliff Curtis, Lola Glaudini, Monet Mazur, Jordi Molla, Miguel Perez, Max Perlich, Emma Roberts
"Blow" is one of two movies opening within a week of each other (along with "The Tailor of Panama") that will be of particular interest to one segment of the movie-going population while disappointing another. If "Blow" is an urbane biopic about a major drug lord responsible for the majority of cocaine that came into the U.S. in the 1970s and not an updated version of "Scarface" as some might expect, then "Tailor," while featuring a womanizing James-Bond sort of feller, is more for lovers of chess matches than video games. The producers of "Blow" are intent on marketing the movie as "based on a true story," the very genre that is often the affliction of successful drama. "Sticks too close to real details to be compelling storytelling" is the usual criticism of biopics, which often come across as cinema verite docudramas, and "Blow" has its share of overly somber storytelling, particularly when conveying the downward spiral of its principal character. Given the charisma of Johnny Depp as cocaine kingpin George Jung, however, and the intense unfolding of the yarn from his beginnings as an child in a tension-filled household to a man who at one point possessed a cash sum of over thirty million dollars, "Blow" is a must-see for all who want proof that the greater the potential profits, the more graphic the risks.
Midpoint in the movie, George Jung's dad, Fred (Ray Liotta), looks over his son's huge Florida villa, late-model foreign sports cars parked outside with a staff of workers keeping them shining, and asks George whether he's happy. Sure, the audience must be thinking, I'll bet we're going to get the usual suggestion that happiness can't be bought and, indeed, George has to hesitate before answering in the affirmative. But as this very rich young man looks back later in his life--at the destruction of his fortune and the loss of his only child's love--we understand how he would have changed everything given a second chance.
Though I had never heard of George Jung, known as the most successful smuggler of cocaine into the U.S. ever (having brought in a whopping eighty-five percent of the coke enjoyed first by the beautiful people and then by partygoers and addicts alike), Ted Demme's down-to-earth brand of filmmaking shows us step by step how he rose to the top of the white-powder kingdom. As with any business, contacts spell success. Get to know the right people and you need not bother with the Sunday New York Times classified. George's motivation to get rich begins when at the age of eight he watches the plumbing business of the father he adores go belly-up to the disdain of his shrewish mother (played by Rachel Griffiths as a bourgeois beast from hell). Shucking the dismal, snowbound Massachusetts scene for sunny Manhattan Beach, California in 1968 together with his obese pal Tuna (Ethan Suplee), he fits right in with the beautiful beach bimbos who all describe themselves as stewardesses. His contacts first with hairdresser Derek (Paul Reubens) and ultimately with the biggest of the Colombia drug lords, Pablo Escobar (Cliff Curtis) lead him from selling marijuana to a weed-crazy college population to the purest cocaine, favored by actors and their hangers on. After jumping bail in two separate instances, he hooks up with party girl Mirtha Jung (Penelope Cruz), who loves him while he's swimming in millions but doesn't want him when he's down and out.
"Blow" lacks the intricate plotting of Steven Soderbergh's more complex and thought-provoking "Traffic" but in a way is of a part with Darren Aronfsky's "Requiem for a Dream." Though in no way as provincial as Brighton Beach's Sara Goldfarb, George shares with the unfortunate woman the effects of the wrong dream. Filmed largely in the Mexican states of Morelos and Guerrero to represents both the heavily fortified digs of Colombian kingpins, directed by Ted Demme with a sober respect for his subject and his audience, and blessed with the magnetism of a man who may well be America's finest young actor, "Blow" is a lively, trenchant tale of greed, sin and redemption.

Coroutine
x2net coroutines are implemented on top of .NET framework iterators, to support suspending and resuming execution within a single thread. x2net coroutines let you work with more intuitive code, binding a couple of sequential tasks into one handler method.
Constraints
Just like .NET framework iterators which they are based on, x2net coroutines do not form a general-purpose coroutine library. There are some constraints using x2net coroutines.
- They can be used within x2net event handlers.
- They can be used within a single thread. So you can use them with builtin
SingleThreadFlow
andThreadlessFlow
(providing that the host thread is single), but not withMultiThreadFlow
.
Time Delay
First, we will look into the most simple one, WaitForSeconds
that introduces a time delay into execution.
using System.Collections;
using x2net;
public class MyCase : Case
{
protected override void Setup()
{
Bind(new MyEvent(), OnMyEvent);
}
IEnumerator OnMyEvent(Coroutine coroutine, MyEvent e)
{
// now
yield return coroutine.WaitForSeconds(10);
// 10 seconds later
}
}
In the above example, the event handler OnMyEvent
starts, waits for 10 seconds, and resumes to finish. Please note that the execution thread doesn't block during the wait time. Once a coroutine handler returns prematurely on a yield
statement, the execution thread continues to invoke as many next handlers as they can. After the specified seconds, the control returns to the next line of the yield
statement and goes on.
Waiting for Events
When you want to wait for a specific event within an event handler, you can use WaitForEvent
. Without coroutines, you would have two separate event handlers for it.
using System.Collections;
using x2net;
public class MyCase : Case
{
protected override void Setup()
{
Bind(new MyEvent(), OnMyEvent);
}
IEnumerator OnMyEvent(Coroutine coroutine, MyEvent e)
{
// now
yield return coroutine.WaitForEvent(new MyOtherEvent());
// On MyOtherEvent posted, or timeout occurred
var result = coroutine.Result as MyOtherEvent;
if ((object)result != null)
{
// result is the MyOtherEvent instance posted
}
else
{
// timeout
}
}
}
Now when the control reaches the yield
statement of the event handler OnMyEvent
, it starts to wait for another event MyOtherEvent
being posted. As said before, the execution thread doesn't block and continues to invoke next handlers. When the desired MyOtherEvent
is posted or the timeout occurs, the control returns to the next line of the yield
statement. You can see that it is possible to check for timeout and acquire the resultant event instance through the Result
property of the Coroutine
object.
Posting Requests and Waiting for Responses
Designing a distributed application, one of the most frequent tasks is sending a request and receiving a response to go on. For this purpose, you can use WaitForResponse
derived from WaitForEvent
.
using System.Collections;
using x2net;
public class MyCase : Case
{
protected override void Setup()
{
Bind(new MyEvent(), OnMyEvent);
}
IEnumerator OnMyEvent(Coroutine coroutine, MyEvent e)
{
// now
yield return coroutine.WaitForResponse(
new MyReq(),
new MyResp());
// On MyResp posted, or timeout occurred
var result = coroutine.Result as MyResp;
if ((object)result != null)
{

MBBS (Bachelor of Medicine and Bachelor of Surgery)
Doctors are healthcare professionals who are capable of diagnosing, treating and monitoring (the condition) of patients.
Doctors use scientific knowledge to heal and help patients. Various methods are used by Doctors to improve the condition of a patient.
Some of the methods are- administering medicines, surgery, therapy and counseling.
It is a noble profession and can be used to touch and influence the lives of people. It is a satisfying profession, where one could use one’s knowledge and skills to bring relief into the lives of people!The profession is quite challenging too. It involves tough working schedules, little to no rest (sometimes), emergency calls etc. Often, a Doctor has to put his/her comfort aside, for the sake of his/her patients! Becoming a Doctor is not an easy task! Pursuing and completing MBBS course will make you a Doctor. But securing admission in a good medical college is a tough task! The competition among aspirants is so enormous that getting a seat in top medical colleges has become very difficult. But with hard work and dedication, no goal is beyond one’s reach! In short, if you want to become a Doctor, you will have to work hard for it.
If you posses qualities such as- good memory, good communication skills, decision making skills, good observational skills, compassion, good academic aptitude etc, you may perform well in this field.COURSE DETAILS
MBBS stands for Bachelor of Medicine and Bachelor of Surgery. It is an UG level Degree medical course. The course duration is 5½ years. The academic program is 4½ years long. 1 year is dedicated towards rotating internship. The academic program is divided into 3 phases. The first phase if 1 year long. The second phase is 1½ years long. The 3rd phase consists of final 2 years. Together, these 3 phases are combined to form the 4½ years long academic program.
After completing the academic program and internship, successful graduates may use the prefix of ‘Doctor (Dr)’. Successful graduates may start practice as medical practitioners and treat patients under supervised or independent setup.
ELIGIBILITY CRITERIA
Minimum age: 17 years Candidate must have passed 10+2 Science stream with Physics, Chemistry and Biology subjects, from a recognized board. Minimum aggregate marks required in PCB subjects- 50%. Minimum marks scored in Biology subject- 50%. Note: Minimum marks criteria may vary (usually around 50% marks). HomeCoursesScience StreamMBBS (Bachelor of Medicine and Bachelor of Surgery)
SYLLABUS
Phase 1 (1st year or I MBBS) subjects- Anatomy Biochemistry Physiology
Phase 2 (2nd year or II MBBS) subjects- Pharmacology Pathology Microbiology Forensic Science
Phase 3 (III MBBS part 1) subjects- Ophthalmology Community Medicine Otolaryngology
Phase 3 (III MBBS part 2) subjects- General Medicine General Surgery Obstetrics and Gynaecology Paediatrics

Only on passing Phase 1 will one be able to take on Phase 2. Similarly, only on clearing Phase 2 will one be able to take on Phase 3 part 1. One may enter Phase 3 part 2 even after not clearing Phase 3 part 1. But to appear for Phase 3 part 2 exam, one must have cleared Phase 3 part 1 successfully.
HIGHER STUDIES AND PG COURSES
This is the age of super specialty! Just an MBBS Degree is not enough in today’s world of cut throat competition! After completing MBBS, graduates may go for the below mentioned traditional PG courses-
MS (Master of Surgery)- 3 years long MD (Doctor of Medicine)- 3 years long PG Diploma- 2 years long DNB (Diploma of National Board)
Using the above mentioned PG courses, one may go for clinical or non clinical studies. PG courses can be used to specialize in a particular discipline/field. Some such areas of specializations are- Obstetrics and Gynaecology, Pathology, Orthopaedics, ENT, Anaesthesia, Paediatrics, Pharmacology, General Medicine, Radiology etc.
After completing any one of the above mentioned PG course, one may go for super specialty course. After MS, you may go for M.Ch. program. After completing MD, you may go for DM program.
Even after going through all these PG and specialty courses, a Doctor must keep the learning process a continuous one! He/she must keep up with the latest developments taking place in the field of medicine and healthcare sector.
Other than the traditional PG courses, one may also go for slightly different courses like- MBA Law PGDMLE (Post Graduate Diploma in Medical Law and Ethics) MMST (Master’s in Medical Science and Technology) M.Tech. (relevant field like Biomedical Engineering) CAREER PROSPECTS AND JOB OPPORTUNITIES With an MBBS Degree, one may practice as a General Practitioner in Government or Private hospitals/clinics. After pursuing PG courses, one’s chances of landing a good job will increase!  Graduates may use CMS entrance test held by the Central Government and join Central Government setups (post of Medical Officer). Graduates may also take part in Government schemes such as Rural Health Mission. Government enterprises such as ONGC, BHEL, OIL etc also recruit medical officers. One may also join hospitals as a Junior Doctor. Joining Armed Forces is another option (PG education at AFMC). Graduates may also work as a tutor at medical schools.

A complete explanation on how to build heatmaps with basic R: how to use the heatmap()
function, how to custom appearance, how to normalize data and more.
How to do it: below is the most basic heatmap you can build in base R, using the heatmap()
function with no parameters. Note that it takes as input a matrix. If you have a data frame, you can convert it to a matrix with as.matrix()
, but you need numeric variables only.
How to read it: each column is a variable. Each observation is a row. Each square is a value, the closer to yellow the higher. You can transpose the matrix with t(data)
to swap X and Y axis.
Note: as you can see this heatmap is not very insightful: all the variation is absorbed by the hp
and disp
variables that have very high values compared to the others. We need to normalize the data, as explained in the next section.
# The mtcars dataset:
data <- as.matrix(mtcars)
# Default Heatmap
heatmap(data)
Normalizing the matrix is done using the scale
argument of the heatmap()
function. It can be applied to row
or to column
. Here the column
option is chosen, since we need to absorb the variation between column.
# Use 'scale' to normalize
heatmap(data, scale="column")
You may have noticed that order of both rows and columns is different compare to the native mtcar
matrix. This is because heatmap()
reorders both variables and observations using a clustering algorithm: it computes the distance between each pair of rows and columns and try to order them by similarity.
Moreover, the corresponding dendrograms
are provided beside the heatmap. We can avoid it and just visualize the raw matrix: use the Rowv
and Colv
arguments as follow.
# No dendrogram nor reordering for neither column or row
heatmap(data, Colv = NA, Rowv = NA, scale="column")
There are several ways to custom the color palette:
terrain.color()
, rainbow()
, heat.colors()
, topo.colors()
or cm.colors()
RColorBrewer
. See list of available palettes here.# 1: native palette from R
heatmap(data, scale="column", col = cm.colors(256))
heatmap(data, scale="column", col = terrain.colors(256))
# 2: Rcolorbrewer palette
library(RColorBrewer)
coul <- colorRampPalette(brewer.pal(8, "PiYG"))(25)
heatmap(data, scale="column", col = coul)
You can custom title & axis titles with the usual main
and xlab
/ylab
arguments (left).
You can also change labels with labRow
/colRow
and their size with cexRow
/cexCol
.
# Add classic arguments like main title and axis title
heatmap(data, Colv = NA, Rowv = NA, scale="column", col = coul, xlab="variable", ylab="car", main="heatmap")
# Custom x and y labels with cexRow and labRow (col respectively)
heatmap(data, scale="column", cexRow=1.5, labRow=paste("new_", rownames(data),sep=""), col= colorRampPalette(brewer.pal(8, "Blues"))(25))
Often, heatmap intends to compare the observed structure with an expected one.
You can add a vector of color beside the heatmap to represents the expected structure using the RowSideColors
argument.
# Example: grouping from the first letter:
my_group <- as.numeric(as.factor(substr(rownames(data), 1 , 1)))
colSide <- brewer.pal(9, "Set1")[my_group]
colMain <- colorRampPalette(brewer.pal(8, "Blues"))(25)
heatmap(data, Colv = NA, Rowv = NA, scale="column" , RowSideColors=colSide, col=colMain )

With .NET projects I have to go back and forth between C# and VB.NET depending on the client. I cannot imagine walking into an environment with the very real possibility that the project could be implemented with any number of scripting languages which introduces a whole new set of concerns. \ There was a recent announcement for IronPython for .NET. I had the same reaction when it was announced. But at least when you do use those scripting languages in this way you have the same core framework so you will have at least a familiarity with the platform if not for the syntax of the scripting language of the week.\r\n\r\nThe ability to use the system tray is encouraging.

With great fanfare, Java 6 was released to the world. Ok, that was a joke. Sun has the ability to make a major release without any fanfare or hullabaloo. Even Spring had a countdown to their 2.0 release. Oh well.
Java 5 was the really big release and added a lot of new functionality to the core language. Back in October of 2005 I wrote about the new features in Java 5 and did a little bit of prognostication about what might be next for Java. Well, if you look at it, you will soon realize that I was totally wrong. It turned into more of a "what I like in scripting languages that I wish I had in Java". Oh well, I won't quit my day job to try and predict the future. Java 5 added number of new language constructs like Generics, foreach loops, and enums. Java 6 on the other hand doesn't seem to add any new language constructs, but is all about extending the APIs. Where Java 5 almost had a theme of catching up to .NET 2.0, Java 6 seems like a relatively random collection of new things.
The API seems to offer everything you could want. It allows you to access Java APIs from the scripting language (this is likely implementation dependent, but is done in the built in JavaScript implementation), it allows you to execute the scripting language methods in Java. It even allows you to mold dynamic languages to Java by forcing them into implementing specific interfaces.
As with most Java APIs, it has an extension mechanism to support various languages. There are already implementations of a lot of different languages available for download, so you can start trying your favorite scripting language.
Check out the Java 6 Scripting Guide for some great examples on various pieces of the API.
Check out this article for a good overview of the changes in JDBC 4.0.
One of the more interesting areas is the ability to transform already loaded Classes. The new classes in java.lang.instrumentation seem like they will be a great boon for a number of different uses. AOP and other Proxy implementations could make use of this. It also seems like this could be a very useful feature in conjunction with the new Scripting support. Languages like Ruby and JavaScript support dynamically adding methods and changing method definitions at runtime. Will this new code allow Script plugin developers to introduce that dynamic functionality into Java?
These are the things that seem most interesting to me. Check out all of the new features in Java 6 for yourself. What are you excited about?

Dear Friend I am Sir John Kempwelch one of the Director of HSBC Bank, London, United Kingdom. On the 2nd of January 2005, I received a call that one of my customer died in the Tsunami Disaster with his wife and only child while on vacation at Phuket Island in Thailand. Since then I have made several enquiries to locate any of my customer's extended relatives and until date have not succeeded. I have contacted you to assist in repatriating the money left behind by my client before it gets confiscated by our bank or declared unserviceable by our bank where this deposit is lodged. Now, the bank Directors has called a board meeting regarding this Fund. So my main motive right now is to share this great opportunity with you by presenting you as the Next of Kin to the Deceased since all his banking details are with me as his personal Account Officer. And the deceased Account valued at US$17.5M Since I have been unsuccessful in locating the biological relatives of my late client, I hereby seek your consent to present you to the bank as next-of-kin of the deceased since you are a foreigner, so that the proceeds of this account valued at US$17.5M can be transferred to you as inheritance and thereafter, you and I can share the money; 50% to me and 40% to you, while 10% will be donated to the Tsunami Disaster Charity Fund. We shall start the first transfer with US$5,000.000.00 (Five Million United States Dollars only), upon the successful actualization of the first transfer without any disappointment from your side, we shall re-apply for the payment of the remaining amount to your account. I have the original copy of Certificate of Deposit of the funds, which will be used to substantiate our inheritance claims. All I require is your consent and honest co-operation to enable us see the deal through. Furthermore, I guarantee that the transaction will be executed under a legitimate arrangement that will protect you from any breach of the law. Please contact me if you are interested immediately via my personal<EMAIL_ADDRESS>to enable us commence on the transaction. Best regards, Sir John Kempwelch. ___________________________________________________________________________ Mail enviado desde el servicio WebMail del Sitio Informática del Caribe - http://www.infocaribe.com.co


HOW TO USE OTP
Simple instruction how does
OTP work ? We have 6 options to choice:
- 1. Print 6x8 char table
- 2. Print coding table
- 3. Print decoding table
- 4. Encode message
- 5. Decode message
- 6. Test alphabet sample string
Let me describe this options
- 1. Print 6x8 char table
When we get first option, the program shows the table which contains 6x8 signs. Program use it for random PAD generator.
Example random 6*8 table:
- 2. Print coding table
Second options shows coding table.
- 3. Print decoding table
Third option shows decoding table.
- 4. Encode message
If we want to encode any message we have to choice option number four. When we get this option, program shows prompt "Write your message to code:". And now we must write the message which we want to encode. For example of message: Hello, my name is Jarek!. After this, program shows prompt about encryption PAD. PAD - What is it? There is key to decoding your message. PAD has always the same quantity of sings what your message. For example of PAD: 2K0=JQ2R5R-S$3QSA-HTo@=.
Message: Hello, my name is Jarek! - 24 signs PAD: 2K0=JQ2R5R-S$3QSA-HTo@=. 24 signs
We have 2 way to generate your PAD of message, either autogenerate of PAD (option "A" - contraction from Auto) or you can write your own PAD, but you must remember about - PAD's signs equal Message signs (option "O" - contraction from Own).
In next step program start encode your message and after encoding shows:
First line shows how many signs has your message,
Second line shows how many signs has your PAD,
Third line shows the message which we want encode - "Coded message is:",
Fourth line shows PAD of message - "Coding pad is:",
Fifth line shows your coded message - "Coded message is:",
For example:
"...

- 5. Decode message
If you want decode your message it is very easy to do. You have to choice option five. Now program shows prompt about starting decoding of message. We must write our encode message and PAD of message. After program shows message which we encode.
For example:
"...
Starting decoding of message!!
Please write your encrypted message: RA6.W
Please write your pad: K=V2i
Decoded message is: HELLo
..."
- 6. Test alphabet sample string
This option show you what kind of sings we use to encode and decode the message.

Boost Library reuse: cost versus benefit trade-offs
A Boost library should not use libraries other than Boost or the C++ Standard Library.
A Boost library should use other Boost Libraries or the C++ Standard Library, but only when the benefits outweigh the costs.
The benefits of using components from other libraries may include clearer, more understandable code, reduced development and maintenance costs, and the assurance which comes from reusing well-known and trusted building blocks.
The costs may include undesirable coupling between components, and added compilation and runtime costs. If the interface to the additional component is complex, using it may make code less readable, and thus actually increase development and maintenance costs.
Negative effects of coupling become obvious when one library uses a second library which uses a third, and so on. The worst form of coupling requires the user understand each of the coupled libraries. Coupling may also reduce the portability of a library - even in case when all used libraries are self-sufficient (see example of questionable usage of <iostream> library below).
Example where another boost component should certainly be used: boost::noncopyable (in boost/utility.hpp) has considerable benefits; it simplifies code, improves readability, and signals intent. Costs are low as coupling is limited; noncopyable itself uses no other classes and its header includes only the lightweight headers <boost/config.hpp> and <cstddef>. There are no runtime costs at all. With costs so low and benefits so high, other boost libraries should use boost::noncopyable when the need arises except in exceptional circumstances.
Example where a standard library component might possibly be used: Providing diagnostic output as a debugging aid can be a nice feature for a library. Yet using Standard Library <iostream> can involve a lot of additional cost, particularly if <iostream> is unlikely to be used elsewhere in the application. In certain GUI or embedded applications, coupling to <iostream> would be a disqualification. Consider redesign of the boost library in question so that the user supplies the diagnostic output mechanism.
Example where another boost component should not be used: The boost dir_it library has considerable coupling and runtime costs, not to mention portability issues for unsupported operating systems. While completely appropriate when directory iteration is required, it would not be reasonable for another boost library to use dir_it just to check that a file is available before opening. C++ Standard Library file open functionality does this at lower cost. Don't use dir_it just for the sake of using a boost library.

Style Guide
This style guide presents a list of sartorial guidelines for anyone participating in the celebrations and Brooks/Crosson-related activities at the City Museum. The primary goal of this guide is to codify and record suggestions that the hosts make about practicality and style.
We suggest that attendees review the following examples to get an idea of the pros and cons of various articles of clothing.
- Good arm mobility for climbing
- Will look nice in pictures
- Jeans provide excellent durability, for crawling
- Acceptable coefficient of friction for slides
- No rips or stains - Will look nice in pictures
- T-shirt is too informal
- Pencil skirt looks nice, but has very poor mobility.
- Looks sharp
- Pants do not limit dexterity bonus, which aids in jumping, sliding, crawling and climbing
- Scores high in agility
- Pants should probably be ironed.
- Polo shirt will look nice in pictures
- Has better abrasion durability than a more delicate shirt
- Looks very sharp
- If you get cold easily, vests are a good way to trap heat close to your body's core
- Suit will look great for formal pictures
- Increases the number of hidden pockets you have
- Suit jacket may induce sweating on a summer day
- Arm movements are restricted
- Points for commitment to the theme
- Wide skirt will allow for enhanced range of motion
- Wicking material will keep you cool while dancing
- Sneakers will provide traction, support, and comfort all day
- Shorts under a skirt reduce awkward situations while climbing
- Lightweight material has good ventilation
- Long length dress will impair crawling and crouched movements
- Botanical camouflage will not hide you well inside the caves
- Star Wars costumes are strongly encouraged
- Well prepared to lead the Rebel Alliance
- This person will have many pictures taken of them
- Note: long skirt may hinder crawling and sliding
- Wear white if you want!
- Wear white if you want!
- Black belt and shoes matches dark grey pants
- More traditional and formal look
- Wearing pants that have thin armor or are easily damaged may prevent you from full exploring the space around you
- Untucked shirt is modern, but a bit too informal
- "Dress shorts" are not a real thing
- Shorts will expose knees to harsh terrain while crawling
- Backs of legs may skid painfully down slides
- Cargo pants are not appropriate in non-tactical situations
- This is a non-tactical situation
- Tuxedo will be too dressy for the occasion
- Bonus points for being an actual cat
- Shoes will stay on feet while crawling, climbing, and dancing
- Closed toe design will protect against injury
- Flat shoes will not fall into cracks
- Chunky heels are more stable than other heels, but may still hinder movement
- Sandal design exposes foot to abrasion
- Will make you appear to be taller than you are
- Very hard to climb in, not recommended
- Could roll your ankle
- Reminder: shoes must be worn at all times
- Platform shoes create an uneven surface, providing a strategic advantage when ascending low inclines, but could make vertical climbing difficult
- Free heel design may allow shoes to accidentally separate from feet, which will hinder exploration and dancing
- Black leather shoes look very nice with dark pants
- Good tread on the bottoms will provide a firm grip on uneven surfaces and braking force at the bottom of slides
- Nice shoes, but might get scuffed up by crawling through tight spaces
- Check soles for appropriate traction: safety is our #1 concern
- Color goes well with khaki pants
- Sports shoes give you +5 on athletic checks
- Closed toes offer superior performance on difficult terrain
- Reasonably clean and won't look out of place with lots of other people wearing them
- High-stick tactical rubber will be overkill for this occasion
- Will wear down quickly on concrete surfaces
- Sticky rubber may cause over braking on slides
- Strong webbing straps firmly afix sandals to the feet
- Sandals with good traction are acceptable for the ladies, more questionable for guys
- Sandals offer less optimal performance than athletic shoes
- Bare feet are not permitted at any time in the City Museum
- Headlamp allows user to see in the dark within a specific radius; this may prove helpful in caves
- Emergency compass and whistle not required to participate in this expedition
- Trail mix is delicious, but outside food and drinks are not permitted in the City Museum

ENTRANCE ANTIPHON
In the midst
of the Church he opened his mouth, and the Lord filled him with the spirit of
wisdom and understanding and clothed him in a robe of glory.
Or:
This is John,
who reclined on the Lord's breast at supper, the blessed Apostle to whom
celestial secrets were revealed and who spread the words of life through all
the world.
The GLORIA can be
said. (English, Latin)
COLLECT
O God, who
through the blessed Apostle John have unlocked for us the secrets of your Word,
grant, we pray, that we may grasp with proper understanding what he has so
marvellously brought to our ears. Through our Lord Jesus Christ, your Son, who
lives and reigns with you in the unity of the Holy Spirit, one God, for ever
and ever.
PRAYER OVER THE OFFERINGS
Sanctify the
offerings we have made, O Lord, we pray, and grant that from the banquet of
this supper we may draw the hidden wisdom of the eternal Word, just as, from
this same source, you revealed it to your Apostle John. Through Christ our
Lord.
COMMUNION ANTIPHON
The Word
became flesh and made his dwelling among us, and from his fullness we have all
received.
PRAYER AFTER COMMUNION
Grant, we
pray, almighty God, that the Word made flesh, proclaimed by the blessed Apostle
John, may, through this mystery which we have celebrated, ever dwell among us.
Through Christ our Lord.


Module forma.neighbourhood
Cell neighbourhood definitions.
The neighbourhood of a cell in a pattern defines which other cells
are considered its neighbours. This is an important definition for many
functions in forma. For example, when finding all cells that border a
pattern in subpattern.edge
a definition of border in terms of a
neighbourhood is required. Cellular automata rules are also defined in
terms of neighbourhoods.
This module provides a class to represent a neighbourhood, along with
examples of typical neighbourhoods such as the Moore
or von Neumann
neighbourhoods.
Usage:
-- Load some neighbourhoods to use with other functions local moore = neighbourhood.moore() local vn = neighbourhood.von_neumann() -- Define a new neighbourhood from a table of forma.cells local cell_list = {cell.new(-1,1), cell.new(1,-1)} local new_neighbourhood = neighbourhood.new(cell_list)
Neighbourhoods
| moore () | The Moore neighbourhood. |
| von_neumann () | The von Neumann neighbourhood. |
| diagonal () | The diagonal neighbourhood. |
| diagonal_2 () | The twice diagonal neighbourhood. |
Functions
| new (neighbour_cells) | Generate a new neighbourhood from a set of cells. |
| categorise (nbh, ip, icell) | Identify which category a cell in a pattern fits into. |
| category_label (nbh) | Returns the category labelling (if it exists) for a neighbourhood. |
| get_ncategories (nbh) | Returns the number of categories for a neighbourhood |
Neighbourhoods
- moore ()
-
The Moore neighbourhood.
Wikipedia entry.
Contains all cells with Chebyshev distance 1 from origin. Used in Conway's Game of Life.
- von_neumann ()
-
The von Neumann neighbourhood.
Wikipedia entry.
Contains all cells with Manhattan distance 1 from origin.
- diagonal ()
-
The diagonal neighbourhood.
Contains all cells diagonally bordering the origin. i.e the Moore neighbourhood with the von Neumann subtracted.
- diagonal_2 ()
-
The twice diagonal neighbourhood.
Contains all cells two cells away from the origin along the diagonal axes.
Functions
- new (neighbour_cells)
-
Generate a new neighbourhood from a set of cells.
Parameters:
- neighbour_cells a list of neighbouring cell vectors
Returns:
-
a forma.neighbourhood comprised of
neighbour_cells
- categorise (nbh, ip, icell)
-
Identify which category a cell in a pattern fits into.
Categorises cells in a pattern according to their neighbourhood
configuration. For each cell in a forma.pattern, there are a finite number
of possible configurations of neighbouring cells. Specifically, each cell
has 2^n possible neighbourhood configurations where n is the number of cells
in the neighbourhood. This method categorises cells according to which type
of neighbourhood they are in.
Parameters:
- nbh the forma.neighbourhood to categorise the cell in
- ip the input pattern
- icell
the cell in
ip
of interest
Returns:
-
the category index of
nbh
that 'cell' belongs to - category_label (nbh)
-
Returns the category labelling (if it exists) for a neighbourhood.
Parameters:
- nbh the neighbourhood to fetch the category labelling for.
Returns:
-
a table of labels, one for each neighbourhood category.
- get_ncategories (nbh)
-
Returns the number of categories for a neighbourhood
Parameters:
- nbh
the
neighbourhood` in question
Returns:
-
the number of categories for neighbourhood
nbh
- nbh
