Just My Blonde Luck
by John Owens
What's the most intense movie you've ever seen? Taxi Driver?
Raging Bull? Maybe Do The Right Thing or White
Heat?
My choice? It's a no-brainer:
Legally Blonde.
Legally
Blonde? Isn't that
the "cute" movie currently in theaters starring Reese
Witherspoon as Elle Woods, the ultimately not-so-ditzy blonde
sorority queen who follows her ex-boyfriend to Harvard Law School?
The classic Hollywood fish-out-of-water tale, right? You can
imagine the pitch -- "It's Clueless meets The
Paper Chase!"
Perhaps. But it has been lurking
in my background for more than five years, and for one evening,
it held me in the greatest suspense since Geraldo went looking
for Al Capone's vault.
Why Legally Blonde?
Well, what else is there to see this summer besides Shrek?
(Not America's Sweethearts, trust me.) Legally Blonde
is a very entertaining movie, but it held my attention so closely
because it had the potential to tell my story at Stanford Law
School.
No, I'm not blonde (at least
not a chemically altered blonde). I'm not a sorority queen. And
I don't think I'm ditzy. What I am is a classmate of Amanda Brown,
the author of the book upon which the movie was based. You see,
for years my classmates and I have heard rumors that Amanda was
working on a tell-all about our class One Elle,
as the book was supposedly titled. Considering that Scott Turow
and Edward Lazarus had little problem exposing the foibles of
their legal classmates and co-workers, why couldn't Amanda do
the same? Yet, when I checked bookstores for her work, I found
nothing. It was as if the book never existed. I thought I was
safe.
Boy was I wrong. Amanda's book
has hit the electronic shelves as an e-book (available at http://www.1stbooks.com/),
and soon will be available in bookstores. And it became a blockbuster
movie -- something not even Turow or Lazarus can claim about
their tell-alls.
Although the movie is set at
Harvard Law School, Stanford Law School is clearly the true setting.
An early orientation scene in which the law students introduce
their degrees before introducing themselves comes straight from
my orientation at Stanford, as do several of Elle's experiences
with obnoxious law students.
But what about me? On the one
hand, I really wanted someone to play me as the smart and dashing
superstud law student that I've convinced myself that I was.
On the other hand, I feared the embarrassing truth: that I was
a law student who studied too much, and was at times so socially
awkward that I left an answering machine message for one of Amanda's
friends that made the famous answering machine message in Swingers
look like a simple wrong number. Would it portray some of my
greatest triumphs, such as posting "Happy 32nd Birthday,
Dalila" flyers all over the law school, knowing full well
that my friend Dalila was turning only 26? Or my greatest failures,
such as telling one law firm partner during on-campus interviews
that I was looking for a firm where I could work 9 to 5? (What
was I thinking?)
It turns out that the movie
was loosely based on Stanford, with no specific references to
my classmates -- or, more important, to me. Apparently, the producers
concluded that my classmates and I were too boring to justify
two hours of celluloid.
But I was not off the hook
yet -- there was Amanda's book. The book made me really nervous,
as Amanda was its sole source, unsoiled by Hollywood's sausage
factory. In large part, my fear was valid. Many of the book's
characters are composites of several people, including my law
school classmates. Crothers, Stanford's first-year student dorm,
plays an early but important role in the book. And Stanford's
sadistic policy of releasing first-year grades on Valentine's
Day -- the Valentine's Day Massacre -- is accurately depicted.
As for me? I came away unscathed.
Or did I? A character named Johnno appears sporadically throughout
the book. Considering that Johnno sounds a lot like John Owens,
I became suspicious. Amanda describes Johnno as a "square
jawed, bright-eyed, athletic entertainment lawyer." I'll
accept that description, even though the "athletic entertainment
lawyer" might be a stretch. Yet the comparison ended once
I read that Johnno had "a busier social life than most students,
and to talk to him was to discover that he was not the brightest
bulb on the tree." That is not true. I had a busier social
life than all students, if you define social life as hangin'
in the Law Review library with Turbo, my ultra-cool black-and-white
Toshiba notebook computer.
Actually, I had no social life
at Stanford, but more important to me, I'd like to think I was
one of the brighter bulbs on the class of 1996 tree. Was Johnno
Amanda's poetic-license revenge? If so, what did I do to anger
Amanda? Or was this all merely a coincidence? There was only
one way to find out: I went to the source, Amanda. She assured
me that Johnno is based on several people, but not me.
Though I am relieved that I
am not Johnno (or even part of Johnno), I'm also disappointed
that I made such a minuscule impression on Amanda in law school.
Few can say they were immortalized in a movie or book, and I
missed my chance, though I'm sure several of my classmates would
happily switch places with me.
Did I learn anything from this
experience, other than a need to keep my vanity in check? This
experience reminded me of how important it is to respect everyone,
no matter who they appear to be. In Legally Blonde, Elle's
classmates don't take her seriously until she wins the big trial.
The lesson I learned from the movie and the book is not to wait
until the big trial to treat someone well; start at the beginning.
After all, that paralegal you've been tormenting might be the
future law clerk deciding whether to grant your motion for an
extension. Or even worse, she could be a screenwriter. And we
all know how big-firm lawyers come off in movies.

---
The last time I used my Arduino MKR WIFI 1010 was way back when I wrote a blog about SWD Debugging the Arduino MKR-WiFi-1010 with Atmel ICE. I was at least kind enough to leave myself a note that once the Microchip Atmel Ice
was used, the bootloader would need to be burned again to program the board over the serial port. Unfortunately the link was not very helpful. Perhaps the contents changed. In any case, I was not able to use the Ardunio IDE to burn the bootloader.
Wow, I tried searching the Arduino forums, and some of the folks there are pretty harsh with people asking simple questions. Either the answer to them was "
don't burn the bootloader" or "read the fine manual". I didn't even bother asking. Instead I'm posting this solution, as yes, sometimes you really do need to burn the bootloader, and yes, I did RTFM
(and still didn't find what I was looking for).
My
prior blog includes all the pics on connections and such. The only thing needed is this information on how to burn the bootloader from within Visual Studio using the Visual Micro Arduino Extension
. Once the Atmel ICE is connected, a fresh bootloader is just a couple of clicks away:

Burst pipe sends steam through Bronx NYCHA apartment with mom, kids inside
by Eyewitness NewsNEW YORK (WABC) -- A woman is fighting to have repairs made at her NYCHA apartment in the Bronx after a pipe burst, filling the apartment with scalding steam.
That is how Stephanie Laguna and her two young children woke up at 4:30 Sunday morning.
"When I opened my eyes I saw what looked like a fire coming out of the bathroom," she said.
It wasn't a fire. A steam pipe in Stephanie's NYCHA Marble Hill Houses apartment had burst, sending steam shooting out of the hole.
It was so hot that she couldn't get any farther than the door.
"Terrifying," she said. "I felt the heat, I left my 3-year-old sleeping, I tried to open all the windows."
Laguna carried 8-month-old Evan in her arms, and 3-year-old Evie stayed in the bed as the problem continued.
Stephanie called NYCHA, but nobody answered, and then she called the FDNY because the steam wouldn't stop.
"They went to the basement to try to cut it off, they couldn't," she said. "They said nothing was labeled. They walked to the maintenance office where they said there would be someone there 24 hours, but there was no one there."
 It continued to pour out of the pipe as workers wrapped a towel around it and closed the door, but water pooled in the bathroom.
So much steam escaped that it peeled off the tiles on the floor.
It also streaked the freshly painted wall, and water filled up trays in the bathroom.

The pipe hasn't been fixed and so far there is no schedule to get it fixed.
Eyewitness News reached out to NYCHA regarding the issue, but there was no word back from them Monday night.

Here is an instructional video that might assist you: https://www.dropbox.com/s/e59dzal4rkkcl2r/twilio.mp4?dl=0 This will require that you have an SSL certificate installed on your webserver to transit a secure connection. This is required by Twilio.
-
Create a new virtual application or add the yap code to an existing folder. The easiest way to get the code there is to upload the latest version there: https://github.com/radius314/yap/archive/2.5.0.zip.
-
Once the application is configured you will need to customize the config.php file. There are several settings there that are documented in that file. There are a number of different ways to utilize the yap platform.
-
NEW» You will need to (
config.php
) enter$twilio_account_sid
and$twilio_auth_token
. You can find this on your account dashboard.
- You will need to ensure that the following
config.php
parameters are set. They should be a service body admin that will be responsible for reading and writing data back to your BMLT. This will not work with the “Server Administrator” account. The user should be at the highest level of access in your BMLT hierarchy that you require access to.
static $bmlt_username = "";
static $bmlt_password = "";
-
Be sure to get a Google Maps API key. Specify this in config.php as the value for
$google_maps_api_key
. Make sure you have “Google Maps Geocoding API” enabled on your credentials. This key must be seperate from your BMLT key with no server restrictions, this is safe because yap never passes the key client side. You can login into your Google API console here: https://console.cloud.google.com/apis/. This article may be useful https://bmlt.magshare.net/google-maps-api-keys-and-geolocation-issues/. -
Try testing that your application actually is functioning properly by opening a browser http://example.com/index.php.
- You will need to set up a Twilio account, and do the following:
- Purchase a phone number (typically you would buy one for your locale, tollfree is pretty much unnecessary these days).
- Configure that number to point to a Webook. It would be something like https://example.com/index.php.
-
You can test whether or not you are properly configured by going to https://example.com/upgrade-advisor.php.
- Make a call to your number and try it out. If there is a problem the debugger in the Twilio console will let you know why. Most likely you did not setup your config.php file correctly.

Library: Iterators
ostream_iterator iterator
Stream iterators allow for use of iterators with ostreams and istreams. They allow generic algorithms to be used directly on streams.
#include <ostream> namespace std { template <class T, class charT, class traits = char_traits<charT> > class ostream_iterator; }
Stream iterators use the standard iterator interface for input and output streams.
The class template ostream_iterator writes elements to an output stream. If you use the constructor that has a second argument, then that string is written after every element (the string must be null-terminated). Since an ostream iterator is an output iterator, it is not possible to dereference values through the iterator. You can only assign to it.
namespace std { template <class T, class charT = char, class traits = char_traits<charT> > class ostream_iterator: public iterator<output_iterator_tag,void,void,void,void> { public: typedef T value_type; typedef charT char_type; typedef traits traits_type; typedef basic_ostream<charT,traits> ostream_type; ostream_iterator(ostream_type&); ostream_iterator(ostream_type&, const char_type*); ostream_iterator(const ostream_iterator&); ostream_iterator& operator=(const T&); ostream_iterator& operator*() const; ostream_iterator& operator++(); ostream_iterator operator++(int); }; }
char_type;
Type of character the stream is built on.
traits_type;
Traits used to build the stream.
ostream_type;
Type of stream this iterator is constructed on.
ostream_iterator (ostream_type& s);
Constructs an ostream_iterator on the given stream.
ostream_iterator (ostream_type& s, const char_type* delimiter);
Constructs an ostream_iterator on the given stream. The null terminated string delimiter is written to the stream after every element.
ostream_iterator (const ostream_iterator& x);
Copy constructor.
const T&
operator= (const T& value);
Insert value into the associated output stream x by calling x << value.
const T& ostream_iterator& operator* (); ostream_iterator& operator++(); ostream_iterator operator++ (int);
These operators do nothing. They simply allow the iterator to be used in common constructs.
#include <iterator> #include <numeric> #include <deque> #include <iostream> using namespace std; int main () { // // Initialize a vector using an array. // int arr[4] = { 3,4,7,8 }; int total=0; deque<int> d(arr+0, arr+4); // // stream the whole vector and a sum to cout // copy(d.begin(),d.end()-1, ostream_iterator<int,char>(cout," + ")); cout << *(d.end()-1) << " = " << accumulate(d.begin(),d.end(),total) << endl; return 0; }

system_kill(3f) - [M_system:SIGNALS] send a signal to a process or a group of processes (LICENSE:PD)
Synopsis
Description
Return Value
Errors
Example
See Also
integer(kind=c_int) function system_kill(pid,sig)
integer,intent(in) :: pid integer,intent(in) :: sig
The kill() function shall send a signal to a process or a group of processes specified by pid. The signal to be sent is specified by sig and is either one from the list given in <signal.h> or 0. If sig is 0 (the null signal), error checking is performed but no signal is actually sent. The null signal can be used to check the validity of pid.
For a process to have permission to send a signal to a process designated by pid, unless the sending process has appropriate privileges, the real or effective user ID of the sending process shall match the real or saved set-user-ID of the receiving process.
If pid is greater than 0, sig shall be sent to the process whose process ID is equal to pid.
If pid is 0, sig shall be sent to all processes (excluding an unspecified set of system processes) whose process group ID is equal to the process group ID of the sender, and for which the process has permission to send a signal.
If pid is -1, sig shall be sent to all processes (excluding an unspecified set of system processes) for which the process has permission to send that signal.
If pid is negative, but not -1, sig shall be sent to all processes (excluding an unspecified set of system processes) whose process group ID is equal to the absolute value of pid, and for which the process has permission to send a signal.
If the value of pid causes sig to be generated for the sending process, and if sig is not blocked for the calling thread and if no other thread has sig unblocked or is waiting in a sigwait() function for sig, either sig or at least one pending unblocked signal shall be delivered to the sending thread before kill() returns.
The user ID tests described above shall not be applied when sending SIGCONT to a process that is a member of the same session as the sending process.
An implementation that provides extended security controls may impose further implementation-defined restrictions on the sending of signals, including the null signal. In particular, the system may deny the existence of some or all of the processes specified by pid.
The kill() function is successful if the process has permission to send sig to any of the processes specified by pid. If kill() fails, no signal shall be sent.
Upon successful completion, 0 shall be returned. Otherwise, -1 shall be returned and errno set to indicate the error.
The kill() function shall fail if:
EINVAL The value of the sig argument is an invalid or unsupported signal number. EPERM The process does not have permission to send the signal to any receiving process. ESRCH No process or process group can be found corresponding to that specified by pid. The following sections are informative.
Sample program:
program demo_system_kill use M_system, only : system_kill use M_system, only : system_perror implicit none integer :: i,pid,ios,ierr,signal=9 character(len=80) :: argumentdo i=1,command_argument_count() ! get arguments from command line call get_command_argument(i, argument) ! convert arguments to integers assuming they are PID numbers read(argument,(i80),iostat=ios) pid if(ios.ne.0)then write(*,*)bad PID=,trim(argument) else write(*,*)kill SIGNAL=,signal, PID=,pid ! send signal SIGNAL to pid PID ierr=system_kill(pid,signal) ! write message if an error was detected if(ierr.ne.0)then call system_perror(*demo_system_kill*) endif endif enddo end program demo_system_kill

Ernakulam bordering the district of Thrissur in the north, Idukki in the East, Alapuzha and Kottayam in the south, Lakshadweep Sea in the west is an amalgam of a hoary heritage and global growth of industry and commerce. For the outside world, Ernakulam is part of Kochi referred to in the history of Kerala as the Queen of Arabian Sea. The densely populated Ernakulam District embodies the achievements of the Kerala State in literacy, industry, trade and commerce. With an inclusive culture, relatively high per capita income and an unstoppable interest of the people in updating themselves of the political, economic, social and cultural happenings in the national and international spheres, Ernakulam represents the high modern phase of the Kerala society.
The flora of this district is tropical. The heavy rainfall combined with moderate temperatures and fertile soil support abundant vegetation. Many of the common plants are found in the coastal area, which forms the lowland region. The midland region is occupied by coconut palms, paddy, tapioca, pepper, pineapple and pulses. The lower slopes of the highland region have teak and rubber.

December 2021 Hacker News Hiring Trends
In the final month of 2021, the remote work trend that exploded in mid-2020 due to the COVID pandemic shows no sign of slowing. Remote-friendly positions account for nearly 77% of the job postings in December's "Ask HN: Who is hiring?" thread.
As for technology trends, there are a couple of interesting updates. First, Java dropped to the #8 programming language, tied with C++. This is likely the lowest, relative to other programming languages, Java has ever been in the ten years worth of data tracked here. Ten years ago, Java was peaking at 20% of postings. Now, it's down to about 6%.
React is still on top of the tech world, though its trend looks to be plateauing. Might we see it on a downward trend in 2022?
Finally, 2021 was the year that Web3 made a big spash onto the scene and so Web3 has now been added to the trends here to track its impact on tech jobs. I'm sure it's only a matter of time until we see job postings asking for 10 years of Web3 experience.

I can't wait to make my websites interactive and free floating. I feel that a signigicant understanding and creativity in javascript creates a unique product. Second to Javascript I'm very excited to learn the back end and begin playing & building my own servers & have the capability to build my own websites completely from scratch through every aspect and requirement of the website. Finally, a project I have in mind is going to require quite a bit of Javascript so I am chomping at the bit to master.

I am a merit scholar with '3' gold medals in grid computing, i used to punch myself whenever i stepped down from the first rank, i was awarded for the best speech about inflation held before '8' american judges [Note: Judges got amazed by my fluency], i voluntarily rejected the job offer offered by TCS. like this i wont tell any lies in my life time, because i had an arrear with grid computing (cleared), i never ever thought about getting first rank, i am little bit weaker in english fluency, i did'nt reject TCS, they rejected me in the final round. But i love to amaze my surrounding people by my creative thoughts. i believe that this one quality of mine will hide all the negative points around me. Ofcourse i'm late, but i'll be the latest..!

This project was done for me and most imporantly it was done by me. The reason behind the creation of this site is very simple, I really like the INTERACTIVE DOODLES which was created by GOOGLE, very much, So i just decided to display my CV with full of interactive features like those doodles. By the way i did not use any third party plugin except easing.js. Even i had created this monitor swiping with my own logic and own code.
The Backup Management System (BMS), The first project of mine which is being actively used by many. The main aim of this project is to allow software developers to work stressfree, by without freaking about the files that he/she going to submit everyday. Because he/she can easily extract the files, which was edited by them on that day. and the edited files will be saved as per the user's desired path. and ofcourse with the same folder structure of their project.
This project was the remake of BMS 1.0 in .Net. The reason behind the rework is, After submitting BMS 1.0 to my boss's table, He asked me to ensure whether it was done by .Net or not. I said that, it was done by using JAVA. So he simply refused it and asked me to redo it in .Net with a biiiiig smile. Anyway he given good a chance for me to dive into .Net. It was actually a kick start in my career, especially in .Net. Because i had done this with in 24 hrs.
CIMS can be abbreviated as College integrated management system. The objective of this project could be easily identified by its name itself.Any way, i should say something about it, This project mainly useful for maintaining the student's repository and also maintaining their fees payment and history. Actually this project was done by 6 clever programmers including me, and it took 6 months to complete.
VPRO who knew about its abbreviation.? My Project manager.? Hmm.. hm. No body knows about it. This name actually given for it by thinking that it would be a stylish one. Apart from that, we all are strong in the concept that are being used inside of this project. This project is actually an inventory management system which provides a feasible way for manufacturers/retailers to maintain their stocks and accounts. It nearly took 6 months to complete.

Contributing
Colour is open source and we happily welcome contributions. This guide will give you an overview on how to contribute.
There are many ways to help:
Reporting a defect, proposing a new feature, an enhancement or commenting existing issues on the Issue Tracker.
Contributing new code by implementing new features or adding examples. For some ideas you can take a look at the issues with the Enhancement and Feature labels or the v9.9.9 milestone.
Maintaining the existing code base, improving the code style and quality, improving the coverage, updating the documentation, fixing bugs, addressing TODOs, etc... Issues with the Defect or Enhancement labels are a good place to start.
Improving the Jupyter Notebooks, we aim to provide a good scientific support to the API and there is still a lot to do.
-
Improving siblings packages:
Participating in discussions on the Mailing List.
Github hosts a First Contributions repository with good information for new comers.
Reporting Issues
The three major issue types one can report on the issue tracker are the following:
We currently use a large set of labels to categorise issues:
-
Defect: Used for any kind of defect reported.
Critical: Used for issues either rendering the software unusable, causing loss of data, or preventing people to work. These issues need to be fixed immediately.
Major: Used for issues which have significant consequences on the ability of people to work but do not lead to the whole API being unusable.
Normal: Used for issues affecting one piece of functionality. Those are usually self-contained and don't impact the overall functionality of the API.
Minor: Used for cosmetic issues that don't prevent the API to run properly.
Enhancement: Used for an enhancement of an existing feature, can also be used for new feature suggestion, although Feature label should be preferred.
-
Feature: Used for a new feature, functionality suggestion.
API: Used for issues related to the API.
Discarded: Used for a discarded / canceled issue.
Discussion: Used to discuss any subject, those issues often turn into features or enhancement.
Distribution: Used to discuss distribution and packaging of the API.
Documentation: Used for issues related to the documentation.
Duplicate: Used for a duplicate issue.
Examples: Used for issues related to the examples.
Postponed: Used for an issue postponed for a future milestone.
Task: Used for a task not directly related to pure programming.
Good First Issue: Used for an issue appropriate for a first time contribution.
Help Wanted: Used for an issue appropriate for a first time contribution but likely harder than a Good First Issue one.
Hacktoberfest: Used for an issue relevant to Digital Ocean's Hacktoberfest.
Defects
You encountered a problem while using Colour, please consider reporting it on the Issue Tracker.
The first thing to do, is to check if there are any existing issues describing your problem, if there is one, you are welcome commenting into it and provide more details. However, please avoid creating duplicates, they add noise to the issue tracker and we will have to label them as Duplicate and close them.
When reporting a defect please provide the output of the following command if possible, and if it makes sense to do so:
$ python -c "import colour;colour.utilities.describe_environment()"
The typical output is something along those lines:
=============================================================================== * * * Interpreter : * * python : 3.7.4 (default, Sep 7 2019, 18:27:02) * * [Clang 10.0.1 (clang-1<IP_ADDRESS>)] * * * * colour-science.org : * * colour : v0.3.13-236-g476410d4 * * * * Runtime : * * numpy : 1.16.5 * * scipy : 1.2.2 * * pandas : 0.24.2 * * matplotlib : 2.2.4 * * OpenImageIO : 2.0.9 * * * ===============================================================================
If you are reporting an exception, please provide the complete traceback, it will help us tremendously understand what happened.
Features & Enhancements
If you would like a new feature to be supported or an enhancement of an existing feature, don't hesitate to link any resources or references you feel like would help its implementation: publications, wikipedia article, etc...
If there is an implementation existing in another language, we will be most likely be able to port it although the licence must be compatible with the New BSD License terms.
We are also running Matlab, so don't hesitate to provide snippets for it if you have functions you would like to be ported.
Contributing Code
Assuming you have something to work on, you will have to get the code and follow the guidelines.
Development for Colour
Here is a succinct overview of the steps you will most likely go through:
$ git clone git@github.com:$USER/colour.git
Navigate to the colour directory:
$ cd colour
Install the development dependencies using Poetry:
$ poetry install --extras "graphviz optional plotting"
If you are in a hurry and not willing to prepend each command with poetry run, it is possible to put the following function in your .bash_profile:
function poem() { if [[ -n "$@" ]]; then poetry env use "$@" else poetry env use 3 fi; if [ -f "pyproject.toml" ]; then source $(poetry env info -p)/bin/activate else echo "The current directory has no associated \"poetry\" capability!" fi; }
Then issuing poem will activate the appropriate virtual environment for your clone.
Install the pre-commit hooks:
$ poetry run pre-commit install
Connect your clone to the original upstream repository by adding it as a remote:
$ git remote add upstream git@github.com:colour-science/colour
You should now have two remotes:
$ git remote -v origin https://github.com/$USER/colour (fetch) origin https://github.com/$USER/colour (push) upstream https://github.com/colour-science/colour (fetch) upstream https://github.com/colour-science/colour (push)
Pull the latest changes from upstream:
$ git checkout develop $ git pull upstream develop
Create a branch for your contribution:
The core developers are using the git flow branching model for most of the development tasks and since the branch name appears in the commit message and for consistency, please use the following branch prefixes:
Feature branch prefix: feature/
Release branch prefix: release/
Hotfix branch prefix: hotfix/
As an example, working to implement Mie Scattering support:
$ git checkout -b feature/mie_scattering
Check if the unit tests and doctests are running properly:
$ poetry run invoke tests
or alternatively:
$ source $(poetry env info -p)/bin/activate $ invoke tests
Commit your changes:
$ git add mie_scattering.py $ git commit -m 'Implement "Mie Scattering" support.'
Push your changes to origin, i.e. your own fork:
$ git push origin feature/mie_scattering
Ensure that the continuous integration suite succeeded.
Visit your repository fork on Github. Your branch should have a green Pull Request button, this will open a pull request and let us know that we have some code to review :)
Code Reviews
Your pull request will be reviewed by the maintainers and any other developer interested by the project.
Every single developer has his code reviewed, this is a natural process helping to raise the codebase quality around a friendly and constructive discussion. Comments will be made on various aspects such as the documentation and references, the code style and its implementation. Those can be discouraging, although they are not meant to criticize but aim at improving the quality of your submission. We all learn from that process and the project ultimately benefits from them.
Guidelines
Most of the conventions used in Colour are the same than NumPy, SciPy and scikit-image.
Overview
We follow the Google Python Style Guide and especially the Python Language Rules although with the main exception being the docstrings / documentation formatted with Numpy Docstrings Style.
The code has to be PEP 8 compliant although but before anything else, it needs to be consistent with the Colour Science litterature:
For example, the base CIE colourspace is CIE XYZ with upper case notation. It can be converted to chromaticity coordinates xy with lower case notation. If we were to fully abide by the PEP 8 recommendations, we would have written a conversion definition as follows:
def xyz_to_xy(xyz): x, y, z = np.ravel(xyz) x, y = x / (x + y + z), y / (x + y + z) return x, y
Abstracting the fact that the above definition is totally undocumented, it can be confusing to understand when we are referencing big X tristimulus value or little x chromaticity coordinate.
For those cases, and there are legions of them in Colour Science, we have decided to go for clarity and consistency with the literature for the object names:
def XYZ_to_xy(XYZ): X, Y, Z = np.ravel(XYZ) x, y = X / (X + Y + Z), Y / (X + Y + Z) return x, y
When the reference is using upper case named variables, we try to follow the same convention, it is unfortunately not PEP 8 compliant but has the benefit of a much easier comparison between the implementation and the reference.
We suggest that contributors follow the same rule.
Python Language Rules
All the code must be covered by unit tests and doctests.
All the code must be documented to the same standard than NumPy, SciPy and scikit-image.
All the code must be checked with the static analysis tool of your choice, e.g. PyCharm , Flake8, or Codacy.
No pull request should be merged without being reviewed and ensuring that the Github Actions continuous integration suite succeeded.
Examples should be provided for new features.
Python Style Rules
Ensure consistency with Colour Science literature first.
Ensure PEP 8 compliance.
-
Try using a close to LaTeX syntax for variables names so that they are easier to compare to the reference.
For instance, a variable defined \(D_{uv}\) in a paper would be defined as D_uv in the code, \(L^*\) as Lstar and \(X_{ab}^{\prime}\) as Xp_ab.
Try using uppercase for author names in definitions:
def CCT_to_xy_Kang2002(CCT):
Please use British English words instead of American English ones as the CIE does, the most important of all being colour instead of color. You can consult the CIE Termlist if any doubts.
Import NumPy as follows:
import numpy as np
Doctests may need ellipsis, don't rely on global nose settings and specify it using the dedicated pragma as follows:
>>> Lab = np.array([100.00000000, -7.41787844, -15.85742105]) >>> Lab_to_LCHab(Lab) # doctest: +ELLIPSIS array([ 100. , 17.5066479...,<PHONE_NUMBER>...])
-
Numbers in the API are usually rounded as follows:
Dataset numbers are kept as is if they are from a known reference or rounded to 15 digits if computed with the API (spectral distributions, chromaticity coordinates, etc...).
Unit tests and doctests input numbers are kept as is if they are from a reference or rounded to 8 digits if computed with the API.
Unit tests output numbers are rounded to 8 digits.
Doctests output numbers trimmed with ellipsis to 7 digits.
-
We recommend a set of values for use with examples and unit tests. A Gist is available with the generating code.
Priority should be given for CIE Standard Illuminant D Series D65 computed values:

Some commonly used dataset elements have aliases like 'cie_2_1931' for 'CIE 1931 2 Degree Standard Observer'. Those are provided for convenience and are reserved for external usage, please use the long form for consistency across the API.
In the same way as above, some computation methods are using a title case like 'Ohno 2013', while the mapping object holding them is case insensitive, please use the title case form for consistency across the API.
Some very big lines sometimes cannot be wrapped (doctests, html links), you can use the # noqa pragma in those cases, although do it in last resort, we have already too much of them.
Avoid / to wrap lines, prefer using the parenthesis ().
The code formatting is performed using Yapf. You can invoke it recursively on a directory as follows:
$ poetry run yapf -ri colour/my_feature
or alternatively:
$ source $(poetry env info -p)/bin/activate $ yapf -ri colour/my_feature
Inline comments must have two spaces.
Ensure that you have blank line at the end of the files.
Ensure that trailing whitespaces are stripped.
Prefix unused variable with an underscore:
_L, a, b = tsplit(Lab)

Commits
A good committing strategy implies that separated commits should be done for any particular changes: One should not commit multiple bugs fixes or large change sets at once.
This unnecessarily increase complexity for any code merge or rollbacks needs and prevent a grainier control over the version control. One exception to this rule is for the initial design steps when creating a new sub-package or feature (please consider squashing the commits), but once the said sub-package is in production, a regular committing strategy should be applied.
Commit messages need to use imperative syntax, the first commit line must be a quick description of the modification content finished by a punctuation mark and can be followed by a detailed description separated by one line break. If the commit fixes a particular issue in the issue tracker, it's advised to state it in the commit message using the following syntax: Closes #32.
Yes: Implement "Yoshi Ohno" correlated colour temperature calculation. This implementation allows for a more precise correlated colour temperature calculation by using a two solutions hybrid approach. Closes #32.
No: Coded new cool cct method
Feature Branches & History
History should never be re-written, although while working on your local feature branch, you may want to provide a cleaner commits history before submitting a pull request. It is perfectly fine to modify your local branch as you wish.
However, if you need to change history on a public and used feature branch, please inform the Colour Developers in order to avoid commit losses or a merging disaster.

$ invoke tag
A typical tag message for a Colour version is as follows:
Create Colour v0.3.15 version.
In the eventuality where the tag creation failed, it might be created manually as follows:$ git tag -a -m "Create Colour v0.3.15 version."
