Node.js implementation of the WebUSB Specification
Node.js > v6.15.0, which includes npm
.
$ npm install webusb
The module exports a default navigator.usb
instance and the USB
class to allow you to instantiate your own usb instances:
To use existing WebUSB scripts, you can simply use the default usb
instance in place of the navigator.usb
object:
var usb = require("webusb").usb;
usb.requestDevice({
filters: [{vendorId: 0x0d28}]
})
.then(device => {
...
})
The first device matching the filters will be returned.
You may want to create your own instance of the USB
class. For example, to inject a device chooser function:
var USB = require("webusb").USB;
function handleDevicesFound(devices, selectFn) {
// If one of the devices can be automatically selected, you can return it
for (var i = 0; i < devices.length; i++) {
if (devices[i].productName === "myName") return devices[i];
}
// Otherwise store the selectFn somewhere and execute it later with a device to select it
}
var usb = new USB({
devicesFound: handleDevicesFound
});
usb.requestDevice({
filters: [{vendorId: 0x0d28}]
})
.then(device => {
...
})

dialog is a UI that can be used as an alternative means of window.alert, window.confirm and window.prompt
How to initialize the properties of the UI, there are two.
You can pass the property values of the UI to setConfig
.
Using the new
you can pass when you initialize the UI.
setConfig([options, callInit=true])
var myDialog = new ax5.ui.dialog();
myDialog.setConfig({
title: [String],
theme: [String],
width: [Number],
onStateChanged: [Function],
btns: [Object],
input: [Object]
});
Easy Way - without setConfig
var myDialog = new ax5.ui.dialog({
title: [String],
theme: [String],
width: [Number],
onStateChanged: [Function],
btns: [Object],
input: [Object]
});
Type: String
Title of dialog.
Type: String
Theme of dialog, ax5dialog themes using six colors defined by the bootstrap is provided.
Type: Number
Dialog width
Type: Function
onStateChanged function is executed when the dialog of the state is changed, this.state state value is passed to this time onStateChanged function.
Type: Object
You can re-define the user’s selection button in dialog.confirm.
btns: {
del: {
label:'Delete', theme:'warning', onClick: function(key){
console.log(key, this);
confirmDialog.close();
}
},
cancel: {
label:'Cancel', onClick: function(key){
console.log(key, this);
confirmDialog.close();
}
},
other: {
label:'Other', onClick: function(key){
console.log(key, this);
confirmDialog.close();
}
}
}
Type: Object
You can re-define the user’s input value in dialog.prompt.
input: {
name: {label:"1. Name", placeholder: "Input your name"},
age: {label:"2. Age", type:"number", value: "22"}
}
alert(String|Options[, callback])
If this is String in the first argument and recognizes the first argument to msg
.
it is possible to redefine all of the options that can be used in setConfig.
If after the alert, user clicks the [OK] button, you need to pass an anonymous function as the second argument of the alert if there is a need of any such actions.
dialog.alert('Alert message', function () {
console.log(this);
});
dialog.alert({
title: 'TITLE',
theme: 'danger',
msg:'Alert message'
}, function () {
console.log(this);
});
confirm(String|Options[, callback])
alert and use the way is similar. Remember only the portion that determines the input of users in callback function confirm is if you can.
confirmDialog.confirm({
title: "Confirm Title",
msg: 'Confirm message'
}, function(){
if(this.key == "ok"){
alert('OK');
}
else if(this.key == "cancel"){
alert('CANCEL');
}
});
prompt(String|Options[, callback])
alert and use the way is similar.
promptDialog.prompt({
title: "Confirm Title",
msg: 'Confirm message'
}, function(){
console.log(this);
// {key: "ok", value: [User Input Data]}
});
promptDialog.prompt({
input: {
name: {label:"1. Name", placeholder: "Input your name"},
age: {label:"2. Age", type:"number", value: "22"}
}
}, function(){
console.log(this);
// this.name, this.age
});
close()
Type: Function
onStateChanged
function can be defined in setConfig method or new ax5.ui.dialog initialization method.
However, you can us to define an event function after initialization, if necessary
myDialog.onStateChanged = function(){
console.log(this);
}

Name: Tim
Gender: Male
Age: 7
Location: Albuquerque, New Mexico
Technology:
Devices: iPad Pro
Operating System: IOS 13
Internet Browser: Google Chrome
Tim uses his iPad constantly, he knows how to use it.
Attitude & Needs:
Tim uses his iPad, but forgets that he has chores to do. He uses Kidtasktic to see the chores he needs to do, and the tasks he needs to complete. He reads through the steps to see how to do them. He earns rewards after he completes all of them in a day, like an extra hour before bedtime. His mom rewards him by giving him Ice Cream when he doesn't forget to do his chores for a whole week. If he forgets to do one chore or a task, he doesn't get Ice Cream. If he forgets multiple or all, his mom punishes him by taking away his iPad for two days. Kidtasktic makes it easier for the mom and Tim, because the mom can add chores to the site, and Tim will see it on his iPad, and he goes through the steps for that chore or task. This way, Tim doesn't have to wonder how to do a task or chore, and he gets rewards!

You can import module-level providers and services to supplement SKY UX functionality and meet needs that SKY UX does not handle. You import providers and services in the app-extras.module.ts file, similar to how you add entry components.
The code sample below illustrates how to import module-level providers and services. It imports DragulaService and DragulaModule into the app-extras.module.ts file to provide a set of components and services that make drag and drop easier. We add DragulaModule to both the imports and exports properties of AppExtrasModule because app-extras.module.ts is not the application's root module.
import { NgModule } from '@angular/core';
import { DragulaService, DragulaModule } from 'ng2-dragula/ng2-dragula';
// Specify entry components, module-level providers, etc. here.
@NgModule({
imports: [
DragulaModule
],
exports: [
DragulaModule
],
providers: [
DragulaService
],
entryComponents: []
})
export class AppExtrasModule { }

Crisp scampi with a vodka tonic batter, hot from the fryer with sharp lemon mayo.
For the scampi, heat a deep fat fryer to 190C/375F. (CAUTION: Hot oil can be dangerous. Do not leave unattended.)
Meanwhile, mix the flour and cornflour in a bowl until well combined.
Pour the tonic water into the flours and whisk in the vodka until the batter is about the consistency of double cream.
Coat the langoustines in the batter and fry in the oil for 3-4 minutes, or until golden-brown and crisp.
Remove the scampi with a slotted spoon and drain on kitchen paper.
For the mayonnaise, place the eggs, white wine vinegar and mustard into a food processor and blend until pale and creamy.
With the motor running, pour in the oil, in a slow steady stream, until the mayonnaise is thick (you may not need all the oil). Mix in the lemon juice.
To serve, pile the scampi in a serving bowl and serve the lemon mayonnaise alongside. Finish with a sprinkle of sea salt and a squeeze of lemon juice.


This is a test with using conllu.js JavaScript library within an RMarkdown document, so that it would be easy to embed UD examples into HTML documents. conllu.js allows displaying graphically trees annotated in CoNLL-U format. The library is done by Sampo Pyysalo. All JavaScript, CSS and HTML files are more less directly taken from the examples on conllu.js website.
For this experiment, a more complete version would have different output for PDF and HTML, but now this is mainly my personal testing. There are also lots of possibilities to modify the Edit-button, as there could be all kind of additional information such as citation info.
suppressPackageStartupMessages(library(tidyverse))
library(conllr)
uig <- read_conll('https://raw.githubusercontent.com/UniversalDependencies/UD_Uyghur/master/ug-ud-dev.conllu')
uig %>%
filter(id == 's901') %>%
as_conllu_div()
Ok, so that works fine. The only problem is that there doesn’t seem to be any API to retrieve individual UD example sentences by language and ID. If I want to discuss one Finnish or Russian example, I don’t want to read the whole files, but could ideally just retrieve the one I need.

This roulade was inspired by the nostalgic flavour of after-dinner mints. Bitter dark chocolate and a cool peppermint fondant centre.
Line a 24x35cm/9½x14in Swiss roll tin with greaseproof paper and preheat the oven to 180C/350F/Gas 4.
Melt the chocolate in a heat-proof bowl set over a pan of simmering water.
Whisk the egg yolks with the sugar in a bowl. Add the cocoa powder, stir to combine until the mixture has thickened, is pale and increased in volume.
Whisk the egg whites in a separate bowl until stiff.
Pour the melted chocolate into the egg yolk and sugar mixture. Stir until the chocolate is fully incorporated.
Gently fold in the egg whites.
Pour the mixture into the prepared tin. Tilt the tin so that the mixture spreads into the corners.
Bake for 18-20 minutes, or until firm and springy to touch.
Once cooked, turn the roulade out onto a piece of greaseproof paper dusted with caster sugar.
Gently remove the lining paper and cover with a damp tea towel. Leave to cool completely.
For the filling, gradually add the icing sugar to the softened butter. Beat until all the icing sugar is incorporated. Add the edible peppermint oil to the milk, and then stir into the buttercream.
Spread the filling onto the cooled roulade, leaving a 1.5cm/¾in gap at each edge. Sprinkle over the chocolate chips.
Using the greaseproof paper to help you, roll up the roulade from one of the short ends. Don’t worry if it cracks a little. Transfer onto a serving plate.

Type every Nigerian language correctly on phones, tablets, iPads and systems. This keyboard helps you type the special letters (əɛɨʊɔŋɗɓƙ, ụndẹrdọts, u̱nde̱rli̱ne̱s) used in Nigerian orthographies and also the ₦aira sign. On touch you access special letters through a long press and on Windows/Mac/Linux by typing a modifier key to transform the previous shape, rather than using deadkeys. Keep pressing the same modifier key to change through several shape options, making it easy to learn and use.
On desktop type the key closest to the symbol you want (a for ə or a̠, e for ɛ or ẹ etc) and then type the semicolon key. Keep typing semicolon to switch between different symbols. After typing the base letter if you want a diacritic (tone mark or nasal) above the letter then type the top left 'back tick' key. For a nasal hold down shift as you type this.
On touch devices, press and hold down a key to see alternatives. For diacritics press and hold on the 'q' key at the top left.

The Saratoga Falcon was the first organization that got me into design.
From Reporter / Layout Artist my sophomore year, my three years on staff culminated in me becoming News Editor my senior year. Through this position, I managed the largest section of our paper (8 out of 28 page in a typical issue).
I assigned and edited all the stories, requested photos and graphics (or made them myself when necessary), and created dummies for each page of layout.
By far my favorite part of being New Editor was having the responsibility of creating the front page of each issue our staff created. My layout was the first thing readers saw when they picked up our paper, and being able to create a good first impression was something that was incredibly rewarding.
Over the course of the year, I had the opportunity to cover some big stories on front page, including ASB having $276,000 for our Sept 25 issue, a big debate about changing our bell schedule as front page dominant for our Feb 12 issue, and a story about a case of human trafficking in Saratoga for the same issue.
The mast head at the top of this page is from the last issue I ever worked on while on staff. If you note the date, you'll see it was our April Fool's issue for which I was Editor-in-Chief. It ended up being both the most fun and most stressful issue I've ever done, and the best way I could have ended my newspaper experience. Having finished my last real issue the day before, I guess by technicality I ended my time on staff as EIC.
Over the course of three years, I also got to write some interesting stories:
•
Yizkor, to remember
•
Students from China at SHS
•
My love for Chromatic Coffee
•
Grad's second startup: UProspie
•
Senior pursues career in art
•
Writing in Crayons for a day

7 Good Reasons to Turn Down a Job Offer

by Harvey DeutschendorfYou’ve been looking for work or are looking to get out of a job that you hate. An offer comes along and your first impulse is to go for it. It seems, what you are offered is better than where you are right now. Not so fast though. It is not always in your best interests to accept every job offer that comes your way. Instead of moving you ahead, accepting a job offer that isn’t right for you may actually set you back. Before you jump at the offer, there are some serious considerations.
7 serious considerations before you accept a job offer:
Will it Move Me in the Direction of My Goals and What I Want?
People take jobs for many wrong reasons; more money, to get away from a job they hate or they just need something to get them away from where they are. We need to look at our goals and passions and see if the job will result in moving me closer to my dreams or passions or away from them. It may not be the dream job, but there needs to be a connection to where we are headed. If not, we could be wasting valuable time that will set us back from reaching our destination. When it comes to accepting a job, we need to be able to step back from all of the information, emotion and any confusion to think critically and come to the best answer/result.
Outlandish Promises Made by the Employer
Beware of an employer that makes promises that sound too good to be true and out of bounds for what an organization such as theirs could reasonably provide. Flattery might be good for our egos, but if it they are making it sound like you are the best thing that ever happened to their organization, our BS detectors should go off. If it sounds too good to be true, it usually is. Be careful and aware when the employer talks about the potential of making money, advancement and training. Question to see how many employees have been able to reach the level the employer is dangling in front of you.
The Organization Has a High Turnover
If we find out that the company has a high staff turnover, our radar should be on full alert. See if you can find out information from former employees and during the interview always ask about the last person that held the position. High staff turnover could mean a negative or even toxic company culture which you do not want to have any part of. If in doubt, check it out.
The Organization is Viewed Negatively in Their Industry and Community
How is the organization viewed by others in the same industry and what kind of a reputation do they have in the community? Have they been involved in an unusually large number of lawsuits? Ask people in the community who have had dealings with the company and contemplate their opinion. Customers and suppliers are a good source of information. Do they belong to associations within the industry and are they involved in supporting the communities in which they are located? We will be associated by others with the organization that we are working for, so it important that we believe in and stand behind them.
Unprofessional Behaviour
Is the employer late for the interview? There are people attending the interview that you weren’t told would be there? No one apologizes for or explain their actions? Are they dressed inappropriately for an interview? Are you asked personal questions that should not be part of an interview? Do they call or text you after working hours with non-related work issues? Have they called someone at your former workplace, not a reference, and have not cleared this with you first? This could be as a result of a poor organization, lack of integrity or lack of respect for you. Either way it should raise alarm bells as to the values and ethics of the organization.
Unanswered Questions or Avoidance by the Employer
When being interviewed for a position we should not be afraid to ask tough questions such as: What happened to the last person in the position? What is the turnover rate? How are people promoted? We should be suspicious if there is any hesitation in answering these questions or if it looks like the employer is trying to hide or avoid answering. An organization that we want to work for is open, transparent and has nothing to hide.
Mismatch Between Their Expectations of Work/Life Balance and Yours
You may want to have weekends and evenings to spend with family but the organization expects you to put their needs first and be available at their beckon call whenever they need you. Even though they may offer many other benefits that you are looking for, sacrificing time with family is not something that you are prepared to do. You need to be very clear about your expectations from the start so avoid getting into a situation you will later regret.

DROP OWNED
Section: SQL Commands (7)Updated: 2012-08-14
Index Return to Main Contents
NAME
DROP OWNED - remove database objects owned by a database roleSYNOPSIS
DROP OWNED BY name [, ...] [ CASCADE | RESTRICT ]
DESCRIPTION
DROP OWNED drops all the objects in the current database that are owned by one of the specified roles. Any privileges granted to the given roles on objects in the current database will also be revoked.
PARAMETERS
- name
- The name of a role whose objects will be dropped, and whose privileges will be revoked.
- CASCADE
- Automatically drop objects that depend on the affected objects.
- RESTRICT
- Refuse to drop the objects owned by a role if any other database objects depend on one of the affected objects. This is the default.
NOTES
DROP OWNED is often used to prepare for the removal of one or more roles. Because DROP OWNED only affects the objects in the current database, it is usually necessary to execute this command in each database that contains objects owned by a role that is to be removed.
Using the CASCADE option might make the command recurse to objects owned by other users.
The REASSIGN OWNED [reassign_owned(7)] command is an alternative that reassigns the ownership of all the database objects owned by one or more roles.
COMPATIBILITY
The DROP OWNED statement is a PostgreSQL extension.

REASSIGN OWNED [reassign_owned(7)], DROP ROLE [drop_role(7)]

Over the last few weeks I’ve written two new tools for the command line: rebuild-sims
and sync-forks
. They join a small but growing family of tools to help with software development. Here’s a bit about the newcomers and how I see that collection growing and staying organized.
At some point a few weeks ago I found I’d corrupted my installs of iOS simulators. I tried fixing it myself to no avail, partly because I was trying to wrap up a release for an app update (of course, with yhr timing). I looked around for a drop in solution online and found this gist: simulator populator xcode, but I had some issues with it:
So, I took the opportunity to rewrite it a bit to improve performance, and serve it in a Gem for ease of distribution and use.
I find a lot of useful code on GitHub, and when I want to use something in a project I try to safely isolate the dependency, part of which involves forking it.
Forking a repository in a DVCS really just means creating a new mirror, a new node in the graph of “remotes” (even your local clones of repositories are really remotes: try cloning from a local repository on your machine, and then look at that clone’s git remotes–they’ll be local paths), to which GitHub adds some helpful UX: if you fork a repo via the GitHub UI, your repository is tagged with information about the original one. Hence, the little “forked from original-owner/repository-name” link under a fork’s name on its GitHub page.
I currently have around 80 forks. I’ve tried keeping them up to date locally to maintain as much control as possible over my fate as a dependee, but that’s a lot of work. For a while I’ve wanted a way to automatically ensure I have a local copy of each fork.
sync-forks
uses the GitHub API via the github_api
Gem to get a list of all your repositories and clone those that are forks. In each local repo, the git remote origin
will point to your fork, and sync-forks
will add a new remote named upstream
that points to the original.
Eventually, I’d like a way to automatically fetch new commits from upstream
s and apply them (using --ff-only
for safety) to the local default branch, and then push to origin
. Maybe later a more sophisticated approach using git pull --rebase
and a stored rerere
strategy could be used for customized forks.
Here’s another pie-in-the-sky idea: automate forking for all your dependencies. I’m not perfect about going around and forking all the repos for dependencies I use in my apps, or even in these Gems. While it is true that package managers may leave caches or checkouts of dependencies in various places, it might be nice to archive them all on a personal server, perhaps. If sync-forks
could crawl all of my Gem or CocoaPod dependencies, fork them on their respective platforms (if possible–GitHub would work, but a privately hosted Git repo probably won’t) and do the usual sync work, then you’d have a total mirror of all the software your apps need to work!
These are distributed in a Ruby Gem named tworingtools
, which provided a nice little learning opportunity to me, since this is the first Gem I’ve created. I also have a set of tools distibuted via Homebrew
in tworingsoft/homebrew-formulae, but I’ve found that approach tougher. Going forward, I’d like to merge these collections.
tworingtools
is currently all housed in a single repository, including specs, which I like. I currently have the Homebrew specs stored in a separate repo from the tools, introducing more complexity. Ultimately I’d like to combine those source repositories into tworingtools
, and add them appropriately to the gemspec. All the better if I can also host the Homebrew specs in that same repository, and target both package managers.

Electoral rules which could help regulate contentious banners 'do not apply in Northern Ireland'
by Brendan HughesELECTORAL rules in Britain which could help regulate contentious banners were never extended to Northern Ireland.
The general election campaign in the north has been marred with controversy over loyalist banners targeting Sinn Féin's John Finucane and the SDLP's Claire Hanna.
In Britain, all printed election material – including material from 'non-party campaigners' – must carry an 'imprint' to show who is responsible for its production.
The requirement is aimed and helping ensure there is transparency about who is campaigning during an election.
However, the rules on imprints for general non-party campaigning do not apply in Northern Ireland – meaning that such campaign material can be shrouded in secrecy.
The Electoral Commission said: "We have consistently called on the UK Government to extend the imprint rules to Northern Ireland – most recently in our response to the UK government policy consultation: Protecting the Debate."
A spokesman said the loyalist posters may constitute "non-party campaigning".
"A non-party campaigner is a group which campaigns in the run-up to elections but is not a political party and does not stand candidates," he said.
"Campaign material from non-party campaigners will be regulated if it can reasonably be regarded as intended to influence voters to vote for or against political parties or categories of candidates."
Non-party campaigners in Northern Ireland must register with the commission if they plan to spend more than £10,000 during an election period.
The imprint rules apply in Britain to all printed election material even if the campaign group isn't required to register due to spending less than the threshold.

Configuring Elastic Beanstalk Environment With .ebextensions
At Captiv8, we are using Amazon AWS to host most of our PHP projects. We are heavily rely on Elastic Beanstalk to help us set up PHP environment, database and load balancer. On top of that, we are also managing our own server image based on Amazon AMI. In this image, we installed additional software and packages that we need for our application. However, this approach has a drawback as it is difficult to maintain the image and track changes. Everytime you need to update the image, you have to create new server, install the new software and export it into new image. This will leave you with bunch of different images and it is hard to tell what are the things that have changed inside each image.
Chef
In order to solve these problems, I decided to find a way to automate the process. My first attempt was trying to use Chef to provision the Elastic Beanstalk environment. I have been using Chef for a while to provision my Vagrant machines. It is powerful and more convenient in compare with bash scripts. Since I am already familiar with Chef, I started looking at tutorials on how to use Chef with Elastic Beanstalk. Most of the tutorials that I found don’t provide easy way to integrate Chef with Elastic Beanstalk. One of them mentions about using AWS OpsWorks with Chef but I think it is overkill for the time being. So, I ditched Chef and start looking for another solution.
ebextensions
ebextensions is another solution that I found after checking the official documentation of Elastic Beanstalk. With this solution, you need to to create .ebextensions folder inside your project and create a file to define what are the packages that you want to install into the environment. Elastic Beanstalk will automatically run the script every time you deploy a new version of the application. Aside from that, you can also tell ebextensions to execute shell script in the instance or changing permission of a file. You can read more details about ebextension here: http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/customize-containers-ec2.html
This is my directory structure at the moment:
Here is the example of my ebextension config file:

Inside my ebextensions config file, I call the shell script which will install additional software. The benefit of using shell script is you have more options and it is much easier to customize the software. Since the .ebextensions folder is copied to the instance, you can tell the shell script to copy a template config file that you have prepared before hand. I hope you find this blog post useful.


public class DbxList
extends java.lang.Object
DbxRecord
or DbxFields
, or might be a temporary list created by a
constructor and not saved in any field. If the list is located in a record (obtained by a
call to DbxRecord.getList(java.lang.String)
or DbxRecord.getOrCreateList(java.lang.String)
) or DbxFields
, the
DbxList
represents a direct view of the value of the field in place. DbxList
methods can be used to change the field, and any changes to the field will be immediately visible
(locally).
Changes to a list field through DbxList
methods will be automatically
merged with other changes made to the same field by combining the effective set of
put (set), insert (add), delete (remove), and move operations which result.
Lists are heterogeneous, able to hold elements of different types. List elements can
hold the same types as field values, with the exception of other lists. List elements
can't be null
. DbxList
elements are addressed by a 0-based index, like
a Java List
. The index at the end of the list can be used only when adding new
elements to the list.

This module is part of PythonCyc, a Python interface module to Pathway Tools.
This code has been tested with Python 2.6.
Pathway Tools (version 18.5 and up) must be running on some machine
with at least the option '-python'. It is also recommended
to start Pathway Tools with the option -lisp, so that the

The global functions defined in this init file can be called before any
PGDB (an organism database in Pathway Tools) has been selected.
In fact, two of these functions, select_organism and
its synonym so, are needed to "select" a PGDB by creating a PGDB object.

PyTorch Governance | Mechanics¶
Summary¶
PyTorch adopts a technical governance structure that is hierarchical.
A community of contributors who file issues, make pull requests, and contribute to the project.
A small set of module maintainers drive each module of the PyTorch project.
They are overseen by core maintainers, who drive the overall project direction.
The core maintainers have a lead core maintainer who is the catch-all decision maker.
All maintainers are expected to have a strong bias towards PyTorch’s design philosophy.
Beyond the maintainers, the community is encouraged to contribute, file issues, make proposals, review pull requests and be present in the community. Given contributions and willingness to invest, anyone can be accepted as a maintainer and provided write access or ownership of parts of the codebase.
Technical governance is strictly separated from business governance. Separating technical from business governance ensures that there is no way for any person or company to “buy their way into” the technical guidance of the project. Additionally, membership in the technical governance process is for individuals, not companies. That is, there are no seats reserved for specific companies, and membership is associated with the person rather than the company employing that person.
Module Maintainers¶
Modules are defined as GitHub repositories within the PyTorch org, or as directories within the core repository pytorch/pytorch. Each module will have its own maintainer group. Maintainer groups are responsible for reviewing and approving commits, improving design, and changing the scope of the module. Each maintainer group may adopt its own rules and procedures for making decisions (majority vote being default). Module maintainers have the right to dispute decisions made by other module maintainers – especially if it affects them. When disputes are made, the module maintainer group should provide a reasonable and public explanation of the dispute, the relevant arguments, and the resolution. In the exceptional cases where module maintainers cannot come to a conclusion themselves, they will escalate to core maintainers for review. The escalations are resolved by the core maintainers in accordance with their rules and procedures.
Each maintainer group should publish publicly available communication for their module (a vision, rough roadmap, design docs, any disputes and dispute resolutions) so that contributors and other interested parties understand the future direction of the project and can participate in discussion.
Responsibilities of the maintainer includes:
Triaging high priority issues of the module
Triaging and reviewing and landing high priority pull requests of the module
Supporting public documentation related to the module
Running public developer meetings
Core Maintainers¶
The core maintainers are expected to have a deep understanding of the PyTorch code base and design philosophies. Their responsibilities include:
Articulating a cohesive long-term vision for the project
Negotiating and resolving contentious issues in ways acceptable to all parties involved
Receiving broad requests for changes from stakeholders of PyTorch and evaluating / accepting them (small module-level requests are handled by module maintainers)
The core maintainers as a group have the power to veto any decision made at a Module maintainer level. The core maintainers have power to resolve disputes as they see fit. The core maintainers should publicly articulate their decision-making, and give a clear reasoning for their decisions, vetoes and dispute resolution.
The core maintainers are admins of the PyTorch GitHub Org and are listed in Maintainers.
Lead Core Maintainer (BDFL)¶
There may be decisions in which the core maintainers cannot come to a consensus. To make such difficult decisions, the core maintainers have an assigned and publicly declared Lead Core Maintainer amongst them, also commonly known in open-source governance models as a BDFL.
The Lead Core Maintainer should publicly articulate their decision-making, and give a clear reasoning for their decisions. The Lead Core Maintainer is also responsible for confirming or removing core maintainers.
Nominating, Confirming and Removing Maintainers¶
The Principles¶
Membership in module maintainer groups is given to individuals on merit basis after they demonstrated strong expertise of the component through contributions, reviews and discussions and are aligned with how the component fits in overall PyTorch direction.
For membership in the maintainer group the individual has to demonstrate strong and continued alignment with the overall PyTorch principles.
No term limits for module maintainers or core maintainers
Light criteria of moving module maintenance to ‘emeritus’ status if they don’t actively participate over long periods of time. Each module maintainer group may define the inactive period that’s appropriate for that module.
The membership is for an individual, not a company.
The Process for Nomination¶
Each module has its own process. Please contact module maintainers for more information. However, if there is no process identified, you can file a request to the core maintainers by submitting this form. Core maintainers are meeting every three months.
If you are submitting a request to the core maintainers, the information in your request must include the following items:
The nominees depth and breadth of code, review and design contributions on the module
Testimonials (positive and negative) of the nominee’s interactions with the maintainers, users, and the community
General testimonials of support from the maintainers
The core maintainers then evaluate all information and make a final decision to Confirm or Decline the nomination. The decision of the core maintainers has to be articulated well and would be public.
The Process for Removal¶
Similar to the process for nomination, anyone in the community can nominate a person to be removed from a Module maintainer position or a Core maintainer position.
A person can also self-nominate to be removed
The core maintainers (excluding persons with conflict of interest) will request or put together more information around the following:
Their activity (or lack of) on the project
Their changing thinking of the space, which results in conflict with the overall direction of the project
Other information that makes them unfit to be a maintainer, such as Code of Conduct issues, their activity outside the scope of the project that conflicts with the project’s values
Conflicts of interest: filial or romantic relationships
The core maintainers then evaluate all information and make a final decision to Confirm or Decline the removal. The decision of the core maintainers has to be articulated well and would be public.
Nominating Core Maintainers¶
Any core or module maintainer can nominate someone to become a core maintainer
The lead maintainer (BDFL) is responsible for evaluating the nomination.
The lead maintainer requests or puts together more information around the strength of the candidate to be a core maintainer:
Letters of support from other core and module maintainers
General letters of support from stakeholders within the PyTorch community
Any new relevant information that is befitting for the candidacy
The lead maintainer evaluates all information and makes a final decision to Confirm or Decline the nomination, with a clear public articulation of their reasoning behind the decision.
Removing the Lead Core Maintainer and Nominating a New Lead Core Maintainer¶
A super-majority of core maintainers (75%) can choose to remove the Lead Core Maintainer
After a removal of the Lead Core Maintainer or in unforeseen circumstances (such as permanent unavailability of the Lead Core Maintainer), the core maintainers follow a Ranked-Choice voting method to elect a new Lead Core Maintainer.
Add, Remove, and Re-Scope Modules and Projects¶
The core maintainers together are responsible for taking decisions on adding, removing and re-scoping new modules in the PyTorch org, either as new repositories in the PyTorch GitHub org, or as folders in the pytorch/pytorch repository.
They invite proposals from members in the community (including themselves) for such changes. The proposals are open-ended, but should have some basic ground-work to make a convincing case to make change. The following is an example approach to this process:
Interview researchers / stakeholders, talk to community, gather issues;
Read papers, attend conferences, build example pipelines based on experience;
Create a state of the world - make sure this change is necessary, for example adding a new project or module is worth the maintenance cost; or removing a project or module will not remove too much value from PyTorch;
Create a proposal; the proposal covers the maintainership, development and community plan once the proposal is approved.
The core maintainers take final decisions on the proposal, articulating the reasoning behind the decision publicly.
Decision Making¶
Uncontroversial Changes¶
Primary work happens through issues and pull requests on GitHub. Maintainers should avoid pushing their changes directly to the PyTorch repository, instead relying on pull requests. Approving a pull request by a core or module maintainer allows it to be merged without further process. Core and module maintainers, as listed on the Maintainers page and within CODEOWNERS ultimately approve these changes.
Notifying relevant experts about an issue or a pull request is important. Reviews from experts in the given interest area are strongly preferred, especially on pull request approvals. Failure to do so might end up with the change being reverted by the relevant expert.
Controversial Decision Process¶
Substantial changes in a given interest area require a GitHub issue to be opened for discussion. This includes:
Any semantic or syntactic change to the PyTorch framework or library.
Backwards-incompatible changes to the Python or C++ API.
Additions to the core framework or library, including substantial new functionality within an existing library.
Removal of core features or platform support
Core and module maintainers ultimately approve these changes.
General Project Policies¶
PyTorch has been established as PyTorch a Series of LF Projects, LLC. Policies applicable to PyTorch and participants in PyTorch, including guidelines on the usage of trademarks, are located at https://www.lfprojects.org/policies/.
PyTorch participants acknowledge that the copyright in all new contributions will be retained by the copyright holder as independent works of authorship and that no contributor or copyright holder will be required to assign copyrights to the project. Except as described below, all code contributions to the project must be made using the 3-Clause-BSD License available here: https://opensource.org/licenses/BSD-3-Clause (the “Project License”). All outbound code will be made available under the Project License. The Maintainers may approve the use of an alternative open license or licenses for inbound or outbound contributions on an exception basis.
FAQ¶
Q: What if I would like to own (or partly own) a part of the project such as a feature area or domain library, for example Linear Algebra or Torch Vision ? This is absolutely possible. The first step is to start contributing to the existing project area and supporting its health and success. In addition to this, you can make a proposal through a GitHub issue for new functionality or changes to improve the project area.
Q: What if I am a company looking to use PyTorch internally for development, can I be granted or purchase a board seat to drive the project direction? No, the PyTorch project is strictly driven by the a maintainer project philosophy and clearly separates technical governance from business governance. However, if you want to be involved in sponsorship and support, you can become involved in the PyTorch Foundation (PTF) and sponsorship through this. You can also have individual engineers look to become maintainers, but this is not guaranteed and is merit-based.
Q: Does the PyTorch project support grants or ways to support independent developers using or contributing to the project? No, not at this point. We are however looking at ways to better support the community of independent developers around PyTorch. If you have suggestions or inputs, please reach out on the PyTorch forums to discuss.
Q: How do I contribute code to the project? If the change is relatively minor, a pull request on GitHub can be opened up immediately for review and merge by the project committers. For larger changes, please open an issue to make a proposal to discuss prior. Please also see the PyTorch Contributor Guide for contribution guidelines.
Q: Can I become a committer on the project? Unfortunately, the current commit process to PyTorch involves an interaction with Facebook infrastructure that can only be triggered by Facebook employees. We are however looking at ways to expand the committer base to individuals outside of Facebook and will provide an update when the tooling exists to allow this.
Q: What if I would like to deliver a PyTorch tutorial at a conference or otherwise? Do I need to be ‘officially’ a committer to do this? No, we encourage community members to showcase their work wherever and whenever they can. Please reach out to<EMAIL_ADDRESS>for marketing support.

An implementation of the Davis-Putnam-Logemann-Loveland (DPLL) algorithm for solving the CNF-SAT problem that runs on Node.js.
This algorithm decides the satisfiability of propositional logic formulae in conjunctive normal form (CNF) - i.e. an AND of ORs.
The dpll source code is available on GitHub, and is released under the MIT license.
Most of this documentation actually comes from wikipedia and is generated by docco.
Disclaimer
This implementation is most definitively not as efficient / complete / advanced / ... (fill in the blanks!) as those entering the SAT competition.
Why JavaScript?
Any application that can be written in JavaScript, will eventually be written in JavaScript (Jeff Atwood).
Tests
This library comes with its unit tests written with mocha. To run them, simply head to the test directory and execute mocha *Test.js.
Quick Start
Let's say we want to solve the following formula:
(a ∨ b) ∧ (¬b ∨ c ∨ ¬d) ∧ (d ∨ ¬e)
Or in plain english:
(a or b) and (not b or c or not d) and (d or not e)
In other words we want to know the values of a, b, c, d and e that make this formula TRUE.
First, create the CNF formula:
var dpll = require('*PATH_TO_DPLL.js*/dpll');
var formula = new dpll.CnfFormula();
var a = {}, b = {}, c = {}, d = {}, e = {};
formula.openClause(a).or(b).close()
.openClauseNot(b).or(c).orNot(d).close()
.openClause(d).orNot(e).close();
Then, create a solver for this formula:
var solver = new dpll.Solver(formula);
Finally, solve the formula and query the returned valuation to get the thruth value of each variable:
var solution = solver.solve();
console.log(solution.get(a));
Solver#solve()
returns undefined
if the formula can not be solved.
If the formula is satisfiable, the returned valuation will NOT contain the variables that have been optimized away. For instance if the formula contains the clause (x ∨ ¬x ∨ y) and x appears nowhere in any other clause of the formula, then x is optimized away and therefore its value is irrelevant - i.e. it could be TRUE or FALSE.
