  • Rust Lang team March update

    Did you know that you can see the lang team's active projects on our project board? We're still experimenting and evolving the setup, but the goal is that it should give you a quick overview of what kinds of things the lang team is focused on, and what stage they are in their development. Our minutes contain a writeup for each active project, but let me call out a few highlights here...

  • DIY primary/foreign key relationships, again

    In a blog post in 2020 I described a problem I was finding in linked tables. One table had a primary key field and the other had a foreign key field that should have referred back to the first table. That wasn't always the case, because the tables didn't always come from a database with referential integrity. The tables were sometimes built in spreadsheets and the primary and foreign keys were entered by hand.

    The defective tables usually have formatting differences or orphaned foreign keys. The formatting issue is that the primary key is something like "Abc_def_236-ghi" and the foreign key is "Abc-def-236-ghi"; close, but no cigar. Orphaned foreign keys are correctly formatted entries with no match at all in the primary key set.

  • Flutter 2.0 reaches stable and adds support for foldable and dual-screen devices

    For a while now, Flutter for Desktop has been in an alpha stage, which meant changing APIs, bugs, and performance issues. With Flutter 2.0, Google has moved its status to somewhere between beta and stable. What does that mean? Well, it’s available in Flutter 2.0 Stable, but Google doesn’t think it’s fully complete yet. It should be fine for production use, but there may be a bug here and there.

  • How I Built a Web Scraper with Beautiful Soup and Used it to Land My First Job

    Landing any job, let alone a first job, can be a difficult process. Employers often tell you that you don't have enough experience for them to hire you. But that means you also won't get an opportunity to gain that experience (like a job).

    Landing a job in tech can feel even more challenging. On the one hand you have to answer interview questions well, like any other job. On the other you have to prove that your technical skills can do the job you're interviewing for.

    These hurdles can be difficult to overcome. In this article I'll share how I built a web scraper to help me land my first job in tech. I'll explain what exactly I built and the key lessons I learned. Most importantly, I'll share how I leveraged those lessons to ace my interviews and land a job offer.

  • We Sent 304,654 Coding Tests to Developers from 156 Countries – Here’s What We Learned

    At DevSkiller, we are known for our detailed industry reports that assist IT recruitment professionals with their hiring decisions. And this past year has been the most diverse and data-heavy set of information ever compiled by our team.

    Despite the circumstances that 2020 brought us, the show must go on. We have compiled 304,654 coding tests sent to developers in 156 countries to create the 2021 DevSkiller IT skills report.

    Whilst it’s easy to point to the big tech multinationals that will indeed profit from a crisis like we’ve had, many other small businesses will have a hard time adapting to the market’s fluctuating demands.

  • Qt 6.0.2 Released

    We have released Qt 6.0.2 today. As a patch release, the Qt 6.0.2 does not add any new functionality but provides bug fixes and other improvements.

  • The Month in WordPress: February 2021

    That was Josepha Haden Chomphosy on WordPress is Free(dom) episode of the WP Briefing Podcast, speaking about the four freedoms of open-source software. Those four freedoms are core to how WordPress is developed. A lot of the updates we bring you this month will resonate with those freedoms.

  • Toolbox your Debian

    Last week I needed a Debian system to test things, I had heard others were using toolbox with Debian images without much trouble so decided to give it a go instead of creating a VM.

    Toolbox only requires a handful utilities to work with any given docker image. After a quick search I stumbled upon Philippe’s post which in turn linked into this PR about an Ubuntu based toolbox image. Looks like the last major issues where worked out recently in toolbox and there isn’t anything extra needed apart the image.

"Futter 2.0 to target developers across all platforms..."

  • Google launches Flutter 2.0 to target developers across all platforms | VentureBeat

    Google has unveiled version 2.0 of Flutter, its open source UI development kit that helps app makers build cross-platform software from the same codebase. While the upgrade ushers in a spread of new features, today’s launch event was perhaps mostly designed to highlight Flutter’s continued transition beyond mobile to support apps wherever they reside — the web, desktop, and even emerging form factors such as foldables.

    The internet giant first unveiled Flutter at its I/O developer conference back in 2017. Version 1.0 arrived on the scene in December 2018 with support for Android and iOS apps, but in the two-plus years since, Google has extended support (somewhat) to include web apps, MacOS, Linux, Windows, and even embedded devices. However, such support has been offered only in early-stage iterations that were either unavailable to most developers, or not designed for production-grade apps — and that is what’s changing today.

  • Google Unleashes Flutter 2 And a New Era of Apps

    In its initial releases, Flutter allowed developers to create apps that run on both Android and iOS. But now Google is setting its sights higher. Much higher.

  • 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
