  • Principles for C programming

    In the words of Doug Gwyn, “Unix was not designed to stop you from doing stupid things, because that would also stop you from doing clever things”. C is a very powerful tool, but it is to be used with care and discipline. Learning this discipline is well worth the effort, because C is one of the best programming languages ever made. A disciplined C programmer will…

    Besides the above plot, which can be difficult to parse even at full size, we offer the following numerical rankings. As will be observed, this run produced several ties which are reflected below (they are listed out here alphabetically rather than consolidated as ties because the latter approach led to misunderstandings). Note that this is actually a list of the Top 23 languages, not Top 20, because of said ties.

    Welcome to the Ides of March, or as we'd like to call it, the IDEs of March. To celebrate, we're asking our readers to let us know which code editing tool they prefer, whether a full-fledged integrated development environment or a simple text editor. Fortunately, there are tons of open source options out there for you to choose from. Which one is your favorite?

  • There’s More to Life Than Code: How to Keep Your Team Engaged

    She found that her engineers actually were most productive when they not only felt like they were part of an engineering team, but when they felt like they were a part of the entire company. When Rent The Runway created cross-functional teams -- with people from all departments working together to solve single problems -- her engineers were at their happiest and most productive.

  • Teaching Children to Code

    Two experiences in my life have shaped the way I try to talk about technology. One was over ten years ago when I taught a room full of retirees, long-term unemployed, and recent immigrants basic computer skills. I realized that I could throw many of the subjects I had studied out of the window and that the best way to teach people was to give them a reason to learn. Fast forward to last year (and a subject I wrote previously on SitePoint) when I taught programming to a group of recent Syrian refugees. Again, I had to throw away much of my own learning and preconceptions and think afresh.

  • [Older] (Emacs) Bug report statistics on OS and arch

  • [PostgreSQL] Parallel Query v2

    A recent Twitter poll asked What is your favorite upcoming feature of PostgreSQL V10? In this admittedly unscientific survey, "better parallelism" (37%) beat out "logical replication" (32%) and "native partitioning" (31%). I think it's fruitless to argue about which of those features is actually most important; the real point is that all of those are amazing features, and PostgreSQL 10 is on track to be an amazing release. There are a number of already-committed or likely-to-be-committed features which in any other release would qualify as headline features, but in this release they'll have to fight it out with the ones mentioned above.

  • Chromium Adds Support For Animated PNGs

  • Life of free software project

    During last week I've noticed several interesting posts about challenges being free software maintainer. After being active in open source for 16 years I can share much of the feelings I've read and I can also share my dealings with the things.

    [...]

    Obviously if you can not cope with the work, let's find more people to do the work. Unfortunately it's not that easy. Sometimes people come by, contribute few patches, but it's not that easy to turn them into regular contributor. You should encourage them to stay and to care about the part of the project they have touched.

    You can try to attract completely new contributors through programs as Google Summer of Code (GSoC) or Outreachy, but that has it's own challenges as well.

    With phpMyAdmin we're participating regularly in GSoC (we've only missed last year as we were not chosen by Google that year) and it indeed helps to bring new people on the board. Many of them even stay around your project (currently 3 of 5 phpMyAdmin team members are former GSoC students). But I think this approach really works only for bigger organizations.

  • Open Source Firmware For A Cheap Programmable Power Supply

    A few months ago, someone clued us in on a neat little programmable power supply from the usual Chinese retailers. The DPS5005 is a programmable power supply that takes power from a big AC to DC wall wart and turns it into a tiny bench-top power supply. You can pick one of these things up for about thirty bucks, so if you already have a sufficiently large AC to DC converter you can build a nice 250 Watt power supply on the cheap.

    [Johan] picked up one of these tiny programmable power supplies. His overall impression was positive, but like so many cheap products on AliExpress, there wasn’t a whole lot of polish to the interface. Additionally, the DPS5005 lacked the ability to be controlled over a serial port or WiFi.

  • Secrets of Maintainable Codebases

    You should write maintainable code. I assume people have told you this, at some point. The admonishment is as obligatory as it is vague. So, I’m sure, when you heard this, you didn’t react effusively with, “oh, good idea — thanks!”

    If you take to the internet, you won’t need to venture far to find essays, lists, and stack exchange questions on the subject. As you can see, software developers frequently offer opinions on this particular topic. And I present no exception; I have little doubt that you could find posts about this on my own blog.

  • Why You Should Consider Open Sourcing Your Software
    Free & Open source software have grown so rapidly in the last few years. Just compare the situation of being ignored and considered like a nerds-movement in the early 2000’s to the situation today in 2017. We surly made a huge advancement so far. Thanks to the amazing ecosystem of open source which links both communities and enterprises together. However, when it comes to individuals, a lot of people are hesitant when it comes to open-sourcing their software. They think that the “secret” behind it will be stolen. They think that they will be releasing their work “for nothing in return” when they do so. That’s definitely false.
  • Caspia Projects and Thunderbird – Open Source In Absentia
    What does this have to do with Thunderbird? I sat in a room a few weeks ago with 10 guys at Clallam Bay, all who have been in a full-time, intensive software training program for about a year, who are really interested in trying to do real-world projects rather than simply hidden internal projects that are classroom assignments, or personal projects with no public outlet. I start in April spending two days per week with these guys. Then there are another 10 or so guys at WSR in Monroe that started last month, though the situation there is more complex. The situation is similar to other groups of students that might be able to work on Thunderbird or Mozilla projects, with these differences:1) Student or GSOC projects tend to have a duration of a few months, while the expected commitment time for this group is much longer.
  • Make Dragonfly BSD great again!
    Recently I spent some time reading Dragonfly BSD code. While doing so I spotted a vulnerability in the sysvsem subsystem that let user to point to any piece of memory and write data through it (including the kernel space). This can be turned into execution of arbitrary code in the kernel context and by exploiting this, we're gonna make Dragonfly BSD great again!

  • Effective Communication in Podcasting
    When I got serious about doing Linux videos on YouTube, I drew on all of that Old Media experience plus I took a few classes to make sure I knew what I was talking about before handing out advice to others. That has led to the EzeeLinux project. The goal of EzeeLinux is to educate folks about Linux and get them started on the right path to success… I have been truly humbled by the response it has gotten. That said, I don’t feel like I’m competing with anyone – the more, the merrier! I honestly feel that Linux and Open Source Software are arguably one of the few truly good things happening in the world today. It brings people from all over the world together and provides a means to get cutting edge technology into the hands of anyone, anywhere who wants to take the time to learn how to use it regardless of their financial situation. That is the kind of power that can quite literally change the world, folks. No one should be left behind in this Information Age. Come to think of it, Ed Murrow would probably do a documentary about Linux if he was still around today… It would be right up his street, I think. It’s the kind of thing he liked to talk about.
