  • How to Use bulk_create() in Django? – Linux Hint

    Django framework can be used to create a web application with a database by writing script in models.py and views.py files of the Django app. The data can be inserted into the database tables by using Django Administration Dashboard or by writing a script in the views.py file. Django Administration Dashboard requires a login for an authenticated user to access the tables of the database. Single or multiple records can be inserted into the database tables by writing a script. bulk_create() method is one of the ways to insert multiple records in the database table. How the bulk_create() method is used to insert the multiple data in a Django database table will be shown in this tutorial.

  • How to Use Django Channel – Linux Hint

    Django is a popular Python framework used to develop web apps using the WGSI (Web Server Gateway Interface) and ASGI (Asynchronous Server Gateway Interface) server specifications. WGSI is used for developing synchronous Python apps, and AGSI is used for developing asynchronous and synchronous web apps. Channel is a useful feature of Django that is used to handle WebSocket, chat protocol, etc. alongside the HTTP protocol. Channel is built on the ASGI server specifications. A two-way interactive communication session between the user’s browser and the server can be opened using a WebSocket. The client initiates the WebSocket connection and the server responds with an accept or close message. The WebSocket messages are pushed into the channel using producers and sent to the consumers that are listening on the channel. This tutorial shows you how to use channels to handle WebSocket messages.

  • Python range() Explained: What It Is and How to Use It - Make Tech Easier

    One aspect of programming that many tutorials don’t tell you upfront is the amount of looping and counting you’ll have to do. As such, any programming language worth its salt will offer ways to enumerate numbers in a repeated way. The Python range sequence type is one of those methods.

  • Monthly Report - February

    Apology for the delay in monthly report, usually I get it released on first day of the month.

    Last month was the shortest month of the year as you all know, so getting things done became relatively harder.

    What is in store this time?

    Well, there were two things that took away all the attentions.

  • Deno 1.8: Node.js alternative gets 'out of the box GPU accelerated machine learning' [Ed: Microsoft Tim is now promoting Deno, as Deno supports Microsoft monopoly on many levels. The Register is not what it once was...]

    The Deno project has released version 1.8, including experimental support for the WebGPU API enabling "out-of-the-box GPU accelerated machine learning."

    [...]

    There is also a new language server, used to support smart features in code editors, that works with both Visual Studio Code and other editors. The TypeScript version in Deno 1.8 has been upgraded to the latest 4.2.

  • Planning the Rust 2021 Edition

    The Rust 2021 Edition working group is happy to announce that the next edition of Rust, Rust 2021, is scheduled for release later this year. While the RFC formally introducing this edition is still open, we expect it to be merged soon. Planning and preparation have already begun, and we're on schedule!

    If you're curious what features Rust 2021 will introduce or what the timeline for getting the edition released on stable is, keep reading!

  • What is Raspberry Pi 4 “Model B”? [Ed: I'm still waiting for them to formally apologise for going behind customers' backs, making secret deals with Microsoft to put Microsoft malware on all those devices]

    Raspberry Pi has conquered the world of SoC (System on a Chip). It has already garnered millions of followers since its release in 2012. Not only is it inexpensive, but it’s also versatile, modular, and multi-purpose. It has become popular not only as a credit-sized computer board but also as a controller in electronic, robotics, and IoT projects. The size, features, and price drive the popularity of the Pi, especially in the DIY community. To keep up with the current technological trends, the tiny board has undergone plenty of upgrades over the years, and there have been many varieties so it can cater to the needs and demands of its users. In 2019, the Raspberry Pi Foundation released the fourth generation of the multi-purpose board, the Raspberry Pi 4 B. It is the most powerful Pi to date, sporting huge upgrades from its predecessors. The compact board is touted to deliver a PC-level performance, and it didn’t disappoint.

  • Kentaro Hayashi: Grow your ideas for Debian Project

    There may be some "If it could be ..." ideas for Debian Project. If idea is concreate and worth to make things forward, it should make a proposal for Project Funding. [...] I'm not confident whether mechanism works, but Debian needs change.

  • Sam Thursfield: Calliope, slowly building steam

    There are some interesting complexities to this, and in 12 hours of hacking I didn’t solve them all. Firstly, Bandcamp artist and album names are not normalized. Some artist names have spurious “The”, some album names have “(EP)” or “(single)” appended, so they don’t match your tags. These details are of interest only to librarians, but how can software tell the difference? The simplest approach is use Musicbrainz, specifically cpe musicbrainz resolve-ids. By comparing ids where possible we get mostly good results. There are many albums not on Musicbrainz, though, which for now turn up as false positives. Resolving Musicbrainz IDs is a tricky process, too — how do we distinguish Multi-Love (album) from Multi-Love (single) if we only have an album name? If you want to try it out, great! It’s still aimed at hackers — you’ll have to install from source with Meson and probably fix some bugs along the way. Please share the fixes!

  • Neovide Is A Graphical Neovim Client Written In Rust

    Neovide is a really cool GUI client for Neovim. Although it essentially functions like Neovim in the terminal, Neovide does add some nice graphical improvements such as cursor animations and smooth scrolling. It even has me thinking about making it my new "vim" alias.

Linux 5.11.13, 5.10.29, 5.4.111, 4.19.186, 4.14.230, 4.9.266, and 4.4.266

Get involved with Mageia, become a Packager

With Mageia 8 just released and development for Mageia 9 getting underway in Cauldron, the unstable branch of Mageia, now is a great time to get involved with packaging. We are starting to look at the features that we want to include for Mageia 9, and as it is so early in the development cycle, now is the time for major developments, or big updates to key pieces of software. This is a great time to join the project as you can propose features you would like to see, help to implement large changes or see how a distribution evolves through development, stabilisation and then is released. If there is an application that you are interested in, if you want to help maintain part of the distribution, or if you want to learn something new, there are many opportunities to do so with the packaging team.

Google does not want you to tell your players about your donation page

I recently updated Pixel Wheels banner image on Google Play. That triggered a review of the game: shortly after the update I received a message telling me Pixel Wheels was "not compliant with Google Play Policies". What nefarious activity does the game engage in? Sneak on users? Mine bitcoins? [...] Meanwhile you can still get the game from F-Droid or itch.io, since they do not have a problem with a link to a donation page. Read more
