  • Custom Piano Tickles the Ivories

    This electronic keyboard is completely designed and built from scratch, including the structure of the instrument and the keys themselves. [Balthasar] made each one by hand out of wood and then built an action mechanism for them to register presses. While they don’t detect velocity or pressure, the instrument is capable of defining the waveform and envelope for any note, is able to play multiple notes per key, and is able to change individual octaves. This is thanks to a custom 6×12 matrix connected to a STM32 microcontroller. Part of the reason [Balthasar] chose this microcontroller is that it can do some of the calculations needed to produce music in a single clock cycle, which is an impressive and under-reported feature for the platform.

  • Hacking A Proper Dash Into The Tesla Model 3 | Hackaday

    The build relies on a CANserver, an ESP32-based device specifically built for hooking up to the CAN bus on Tesla vehicles and sharing the data externally. The data can then be piped wirelessly to an Android phone running CANdash to display all the desired information. With the help of an aftermarket dash clip or a 3D printed custom mount, the phone can then be placed behind the steering wheel to display data in the usual location.

  • Firefox Nightly: These Weeks in Firefox: Issue 108
  • Celebrating Data Privacy Day

    Happy International Data Privacy Day! While January 28 marks a day to raise awareness and promote best practices for privacy and data protection around the world, we at Mozilla do this work year-round so our users can celebrate today — and every day — the endless joy the internet has to offer.

    We know that data privacy can feel daunting, and the truth is, no one is perfect when it comes to protecting their data 24/7. At Mozilla though, we want to make data protection feel a bit easier and not like something else on the never-ending life to-do list. We build products that protect people online so they can experience the best of the web without compromising on privacy, performance or convenience. The internet is too good to miss out on — we’ll take care of securing it so you can focus on exploring and enjoying it.

    To accomplish this, we started with square one: our Firefox browser — enhancing its privacy and tracking protections over the past year, while improving its user experience to make surfing the web less dangerous and more carefree.

    Despite how it sounds, you don’t need to be a hacker to make use of an encrypted connection. Whether you’re online shopping or want to make sure your login credentials are safe from attackers, we’re working on ensuring your browsing experience is secure from start to finish. That’s why, when you open up a Private Browsing tab on Firefox, you can be confident that your information is safe thanks to our HTTPS by Default offering, which ensures the data you share with and receive from a website is encrypted and won’t be able to be intercepted, viewed or tampered with by a hacker. To take this one step further, we’re also working with Internet Service Providers like Comcast and other partners through our Trusted Recursive Resolver program, to begin making DNS encryption the default for Firefox users in the US and Canada.

  • Abuse & Sex Crimes at FOSDEM and Open Source tech events

    All these people have conflicts of interest. For example, Molly herself was secretly sleeping with Chris Lamb when he was leader of Debian. Imagine a woman comes to Molly's team to make an abuse complaint about Lamb or one of his close friends.

    [...]

    Women trusting women simply because they are women is not a good choice.

    There are numerous examples of women like Molly who have been sympathetic to or even in cahoots with male abusers.

  • What is MongoDB, and how does it work? | FOSS Linux

    MongoDB is the most common and widely used NoSQL database. It is an open-source document-oriented DB. NoSQL is used to refer to ‘non-relational’. This means that the MongoDB database is not based on tabular relations like RDBMS as it provides a distinct storage and data retrieval mechanism.

    The storage format employed by MongoDB is referred to as BSON. The database is maintained by MongoDB Inc. and is licensed under the Server-Side Public License (SSPL).

  • Here's what's new and changed in Kodi 20 'Nexus' Alpha 1

    Yesterday, we revealed that the next big version of Kodi had hit an important milestone. Nightly builds of Kodi 20 'Nexus' have been available for months, but now there’s a much more stable release for users to download. Although it’s only a pre-release build, and therefore will likely have some bugs to watch out for, Kodi 20 'Nexus' Alpha 1's arrival will excite a lot of people. Team Kodi is very proud of this release, and highlights the following changes and new features.

  • MiTubo 1.0: playlist support, new “website” | Mardy

    Expanding a bit on the points above, the first thing worth saying is that the choice of releasing this version as “1.0” does not mean that it's more stable than the previous ones; it just means that I'm rather satisfied with the feature set, and that I believe that the program is ready for more widespread use. This is also the reason why I decided to prepare a web page for it: mardy.it/mitubo. I didn't go for a completely separate website, unlike what I previously did for Mappero Geotagger, PhotoTeleport and Imaginario (which reminds me that I haven't been working on the latter for a long time! I should try to correct this soon!), both because this way it's simpler to publish news about it (I'll continue doing that here, instead of cross-posting in two sites), and because having it in the same domain might be mutually beneficial for the SEO ranking of the blog and of MiTubo.

  • Adriaan de Groot: Blue Systems Farewell

    Calamares serves the needs of several dozen Linux distributions, large and small. I’ve been running the Calamares project for five years now, sponsored by Blue Systems who have supported the Calamares project since its beginning and through two maintainers now. After these five years, I have decided to hand in my badge and move on to different things. This means that I’m no longer paid to spend three days a week on Calamares and my involvement is going to be dialed back to incidental-volunteer-contributor. This means that maybe I’ll finally ignore Linux distro’s and sit down to make it work for FreeBSD.

  • Strengthening digital infrastructure: A policy agenda for free and open source software

    While there is little debate that digital forces are playing an increasingly crucial role in the economy, there is limited understanding of the importance of the digital infrastructure that underlies this role. Much of the discussion around digital infrastructure has focused on broadband availability (which is certainly important), but the role of free and open source software (FOSS or OSS) has gone underappreciated. FOSS—software whose source code is public, is often created by decentralized volunteers, and can be freely used and modified by anyone—has come to play a vital role in the modern economy. It is baked into technology we use every day (cars, phones, websites, etc.), as well as into various aspects of critical infrastructure including our finance and energy systems.

  • Improve legibility and reduce layout shifts with x-height adjustments

    There’s more to setting the text size on your webpages than just the CSS font-size property. It only controls the size of majuscule (“uppercase”, e.g. “A”) letters, numbers, and punctuation. The size of minuscule (“lowercase”, e.g. “a”) letters is left up to the font. [...] Unfortunately, font-size-adjust is only supported in Firefox. It has been supported by this browser for over a decade already. It was implemented in Chrome for almost half a decade, but it has been left to rot behind the Experimental Web Platform features flag. It’s not implemented in Safari.
