iCEBreaker, The Open Source Development Board for FPGAs

Filed under
Development
Hardware

The Hackaday Superconference is over, which is a shame, but one of the great things about our conference is the people who manage to trek out to Pasadena every year to show us all the cool stuff they’re working on. One of those people was [Piotr Esden-Tempski], founder of 1 Bit Squared, and he brought some goodies that would soon be launched on a few crowdfunding platforms. The coolest of these was the iCEBreaker, an FPGA development kit that makes it easy to learn FPGAs with an Open Source toolchain.

Programming/Development: mental illness, newt, and more

  • One developer's road: Programming and mental illness

    The next year, I went to college and learned about SUSE Linux 6.1 and the Java SE 1.2 programming language. Another student introduced me to free software and the GNU GPL License and helped me install SuSE 7.1 on my new Compaq Evo N160c notebook.

    There was no more Microsoft software on my computer. The GNU/Linux operating system was exactly what I wanted, offering editors, compilers, and a command line that did auto-completion.

    Six months later, I installed Debian GNU/Linux. Since YaST2 was just a front end to configuration files, I had to use Debian Potato. My bootloader of choice was LILO, and the Second Extended File System was reliable—not buggy, like ReiserFS.

    In spring 2002, I read a book about the C programming language. I wanted to learn to do UIs like javax.swing, and a friend recommended Gtk+ 2.0, which was about to be released. At this point, I stopped using the KDE Desktop Environment. Gnome 2 was different and provided anti-aliased fonts with hinting. I used it to play Chromium B.S.U., and KNOPPIX did the magic.

  • newt

    I've been helping teach robotics programming to students in grades 5 and 6 for a number of years. The class uses Lego models for the mechanical bits, and a variety of development environments, including Robolab and Lego Logo on both Apple ][ and older Macintosh systems. Those environments are quite good, but when the Apple ][ equipment died, I decided to try exposing the students to an Arduino environment so that they could get another view of programming languages.

    The Arduino environment has produced mixed results. The general nature of a full C++ compiler and the standard Arduino libraries means that building even simple robots requires a considerable typing, including a lot of punctuation and upper case letters. Further, the edit/compile/test process is quite long making fixing errors slow. On the positive side, many of the students have gone on to use Arduinos in science research projects for middle and upper school (grades 7-12).

    In other environments, I've seen Python used as an effective teaching language; the direct interactive nature invites exploration and provides rapid feedback for the students. It seems like a pretty good language to consider for early education -- "real" enough to be useful in other projects, but simpler than C++/Arduino has been. However, I haven't found a version of Python that seems suitable for the smaller microcontrollers I'm comfortable building hardware with.

How Java has stood the test of time

Filed under
Development

Java initially appeared in 1995, evolving from a 1991 innovation called "Oak." It was apparently the right time for engineers looking to grow distributed systems. Some of the more popular languages back then — C, C++, and even Cobol for some efforts — involved steep learning curves. Java's multi-threading, allowing the concurrent execution of two or more parts of a program, ended the struggle to get multi-tasking working.

Java quickly became the de facto language for mission-critical systems. Since that time, new languages have come and gone, but Java has remained entrenched and hard to replace. In fact, Java has stood as one of the top two computing languages practically since its initial appearance, as this Top Programming Languages article suggests.

  • The Linux Direct Rendering Manger Subsystem Poised To Have A Second Maintainer

    For hopefully helping out with code reviews and getting code staged in a timely manner before being upstreamed to the mainline Linux kernel, Daniel Vetter of the Intel Open-Source Technology Center is set to become a co-maintainer. 

    Daniel Vetter who has been with Intel OTC for a number of years working on their Linux graphics driver has proposed becoming a DRM co-maintainer, "MAINTAINERS: Daniel for drm co-maintainer...lkml and Linus gained a CoC, and it's serious this time. Which means my [number one] reason for declining to officially step up as drm maintainer is gone, and I didn't find any new good excuse."

  • Processing CloudEvents with Eclipse Vert.x

    Our connected world is full of events that are triggered or received by different software services. One of the big issues is that event publishers tend to describe events differently and in ways that are mostly incompatible with each other.

    To address this, the Serverless Working Group from the Cloud Native Computing Foundation (CNCF) recently announced version 0.2 of the CloudEvents specification. The specification aims to describe event data in a common, standardized way. To some degree, a CloudEvent is an abstract envelope with some specified attributes that describe a concrete event and its data.

  • GCC 9 Guts Out The PowerPC SPE Support

    It should come as no surprise since it was deprecated in this year's GCC 8 release, but the PowerPC SPE code has been removed.

    This isn't to be confused with conventional POWER/PowerPC but rather PowerPC SPE that is for the "Signal Processing Engine" on older FreeScale/IBM cores like the e500. It's not all that important these days and doesn't affect newer versions of the 64-bit Power support.

  • Nick Cameron: Rust in 2022

    In case you missed it, we released our second edition of Rust this year! An edition is an opportunity to make backwards incompatible changes, but more than that it's an opportunity to bring attention to how programming in Rust has changed. With the 2018 edition out of the door, now is the time to think about the next edition: how do we want programming in Rust in 2022 to be different to programming in Rust today? Once we've worked that out, lets work backwards to what should be done in 2019.

    Without thinking about the details, lets think about the timescale and cadence it gives us. It was three years from Rust 1.0 to Rust 2018 and I expect it will be three years until the next edition. Although I think the edition process went quite well, I think that if we'd planned in advance then it could have gone better. In particular, it felt like there were a lot of late changes which could have happened earlier so that we could get more experience with them. In order to avoid that I propose that we aim to avoid breaking changes and large new features landing after the end of 2020. That gives 2021 for finishing, polishing, and marketing with a release late that year. Working backwards, 2020 should be an 'impl year' - focussing on designing and implementing the things we know we want in place for the 2021 edition. 2019 should be a year to invest while we don't have any release pressure.

    To me, investing means paying down technical debt, looking at our processes, infrastructure, tooling, governance, and overheads to see where we can be more efficient in the long run, and working on 'quality of life' improvements for users, the kind that don't make headlines but will make using Rust a better experience. It's also the time to investigate some high-risk, high-reward ideas that will need years of iteration to be user-ready; 2019 should be an exciting year!

  • A Java Developer Walks Into A Ruby Conference: Charles Nutter’s Open Source Journey

    As a Java developer, Nutter began looking for an existing way to run Ruby within a Java runtime environment, specifically a Java virtual machine (JVM). This would let Ruby programs run on any hardware or software platform supported by a JVM, and would facilitate writing polyglot applications that used some Java and some Ruby, with developers free to choose whichever language was best for a particular task.

  • Metropolisim aims to be the deepest city-building simulation experience ever, will have Linux support
    Metropolisim from developer Halfway Decent Games is releasing next year, with a pretty bold aim to be the deepest city-building simulation experience ever.
  • Monster Prom, the dating sim that won me over is now available on GOG
    Visual novels and dating sims aren't something I'm usually into, however Monster Prom is actually funny and worth playing and it's now available on GOG. I know we have a number of GOG fans here, so hopefully this will be interesting for you. As always, we try to treat all stores equally with release info.
  • Kingdom Two Crowns will be coming to Linux after all with the Quality of Life update
    Kingdom Two Crowns, the third in the Kingdom series released recently for Windows and Mac. It looked like we weren't getting it, but it's now confirmed to be coming. In their new roadmap post on Reddit and Steam, under the "QoL #01 Update" (Quality of Life Update) they noted that they will add "Add SteamOS (Linux) Support". This update is due out sometime early next year. This is really nice news, it's good to know they didn't give up on supporting Linux after all.
  • Steam Link for the Raspberry Pi is now officially available

  • Valve in it for the 'long haul' with Artifact, first update out and a progression system due soon
    Artifact, the big new card game from Valve isn't doing so well but Valve won't be giving up any time soon. The first major update is out, with a progression system due soon. At release, it had around sixty thousand people playing and that very quickly dropped down hard. Harder than I expected, a lot worse than Valve probably thought it would too.
  • Bearded Giant Games open their own store with a 'Linux First Initiative'
    Bearded Giant Games, developer of Ebony Spire Heresy have announced their new online store along with a 'Linux First Initiative'. I know what you're thinking already "not another store", but fear not. For now, it's mainly going to be a place for them to sell their games directly. Speaking about it in a blog post, they mentioned how they hate having to check over multiple forums, channels, emails and so on to stay up to date and they wish "to spend more time giving love to my projects instead of updating 4 different distribution channels, translating pages, writing different press releases and making separate builds"—can't argue against that.

    Meeple Station, the space station building sim that the developers say is like Rimworld in space can now be pre-ordered with instant beta access. While we don't like the idea of pre-orders, getting access to the beta right away is a decent way to do it. Sadly, their Kickstarter campaign actually failed which I didn't notice. Making sure that wasn't the end of it, the developer Vox Games decided to go the Early Access route. They weren't left out in the cold of space though, as they also recently announced that Indie DB will be publishing their game. Under the label of Modularity, this will be the first title published by Indie DB.
  • Heroes of Newerth drops support for Linux and Mac
    Heroes of Newerth, the MOBA originally from S2 Games which is now handled by Frostburn Studios has dropped Linux and Mac support. [...] I'll be honest here, I couldn't care less about it personally. The last time i tried it, it was the single most toxic experience I've ever had in an online game. I've played a lot of online games and even so it was still at a level I had not seen before. I tried to go back to it a few times, never with a happy ending. Still, sad for any remaining Linux (and Mac) fans of the game. Looking over some statistics, it's not popular with viewers either. Around 180 on Twitch compared with nearly 100K for League of Legends and over 50K for Dota 2.

A Look At The Clear Linux Performance Over The Course Of 2018

With the end of the year quickly approaching, it's time for our annual look at how the Linux performance has evolved over the past year from graphics drivers to distributions. This year was a particularly volatile year for Linux performance due to Spectre and Meltdown mitigations, some of which have at least partially recovered thanks to continued optimizations landing in subsequent kernel releases. But on the plus side, new releases of Python, PHP, GCC 8, and other new software releases have helped out the performance. For kicking off our year-end benchmark comparisons, first up is a look at how Intel's performance-optimized Clear Linux distribution evolved this year. For getting a look at the performance, on four different systems (two Xeon boxes, a Core i5, and Core i7 systems), the performance was compared from Clear Linux at the end of 2017 to the current rolling-release state as of this week.
