  • Arduino Blog » Time to get creative – the Arduino Day Community Challenge is coming

    Every year, one of Arduino Day’s biggest highlights is the Community Challenge, and 2021 is no different.

    As you read this, we’re working feverishly behind the scenes to get this year’s challenge ready, so you can start submitting your projects for a chance to win some awesome Arduino goodies.

    Keep an eye out right here on the Arduino blog early next week for all the details, and how to enter your projects into the competition. But in the meantime, why not spend the weekend deciding what kind of cool, creative and crazy contraptions you might want to build?

  • STM32WL based LoRa-5E development kits go for $19.90 and up

    The LoRa-E5 STM32WL module we covered last month can now be found in two LoRaWAN development kits from Seeed Studio with the ultra-compact LoRa-E5 mini board, and the Arduino UNO shaped LoRa-E5 board with more I/Os.

    Both boards support the LoRaWAN protocol with global frequencies and can achieve a transmission range of up to 10 km with ultra-low power consumption.

  • NXP unveils ultra-secure i.MX9 and low-power i.MX8ULP SoCs

    NXP previewed an NPU-enabled “i.MX9” platform and unveiled low-power, Cortex-A35 based i.MX8ULP and Azure Sphere enabled i.MX8ULP-CS SoCs — all with and “Energy Flex” power management and “EdgeLock” security.

    NXP offered a glimpse into some foundational technologies of an upcoming i.MX9 family of processors, including “EdgeLock” on-die security, RISC-V-based “Energy Flex” power management, and the Arm Ethos U-65 microNPU for AI acceleration. The Netherlands-based chipmaker did not, however, detail the CPU architectures, core counts, performance, GPUs, and other details.

  • 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.

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
