  • The Sprint

    Hi -)) haven’t posted for some time, because I was busy travelling and coding for the first half of the month. From Aug 5 to Aug 9, I went to the Krita Sprint in Deventer, Netherlands.

    According to Boud, I was the first person to arrive. My flight took a transit via Hong Kong where some flights were affected due to natural and social factors, but fortunately mine was not one of them. Upon arrival in Amsterdam I got a ticket for the Intercity to Deventer. Railway constructions made me take a transfer via Utrecht Centraal, but that was not a problem at all: the station has escalators going both up to the hall, and down to the platforms (in China you can only go to the hall by stairs or elevator (which is often crowded after you get off)). When I got out of Deventer Station, Boud immediately recognized me (how?!). It was early in the morning, and the street’s quietness was broken by the sound of me dragging my suitcase. Boud led me through Deventer’s crooked streets and alleys to his house.

    For the next two days people gradually arrived. I met my main mentor Dmitry (magician!) and his tiger, Sagoskatt, which I (and many others) have mistaken for a giraffe. He was even the voice actor for Sago. He had got quite a lot of insights into the code base (according to Boud, “80%”) and solved a number of bugs in Krita (but he said he introduced a lot of bugs, ha!). Also I met David Revoy (my favourite painter!), the author of Pepper and Carrot. And Tiar, our developer who started to work full-time on Krita this year; she had always been volunteering to support other Krita users and always on the IRC and Reddit. And two of other three GSoC students for the year: Blackbeard (just as his face) and Hellozee. Sh_zam could not come and lost communications due to political issues, which was really unfortunate (eh at least now he can be connected). It is feels so good to be able to see so many people in the community – they are so nice! And it is such an experience to hack in a basement church.

  • How UCLA Library preserves rare objects with open source

    The University of California, Los Angeles, (UCLA) Library houses a collection of millions of rare and unique objects, including materials dating from 3000 BCE, that could be damaged, destroyed, or otherwise threatened if they were displayed.

    To make these special collections widely available while keeping them secure, the UCLA Library has been modernizing its digital repository, which was established 15 years ago on now-outdated software.

Linux on the mainframe: Then and now

Last week, I introduced you to the origins of the mainframe's origins from a community perspective. Let's continue our journey, picking up at the end of 1999, which is when IBM got onboard with Linux on the mainframe (IBM Z). These patches weren't part of the mainline Linux kernel yet, but they did get Linux running on z/VM (Virtual Machine for IBM Z), for anyone who was interested. Several efforts followed, including the first Linux distro—put together out of Marist College in Poughkeepsie, N.Y., and Think Blue Linux by Millenux in Germany. The first real commercial distribution came from SUSE on October 31, 2000; this is notable in SUSE history because the first edition of what is now known as SUSE Enterprise Linux (SLES) is that S/390 port. Drawing again from Wikipedia, the SUSE Enterprise Linux page explains: Read more

  • Why Open Source continues to be the foundation for modern IT

    Open source technology is no longer an outlier in the modern world, it's the foundation for development and collaboration. Sitting at the base of the open source movement is the Linux Foundation, which despite having the name Linux in its title, is about much more than just Linux and today is comprised of multiple foundations, each seeking to advance open source technology and development processes. At the recent Open Source Summit North America event held in San Diego, the width and breadth of open source was discussed ranging from gaming to networking, to the movie business ,to initiatives that can literally help save humanity. "The cool thing is that no matter whether it's networking, Linux kernel projects, the Cloud Native Computing Foundation projects like Kubernetes, or the film industry with the Academy Software Foundation (ASWF), you know open source is really pushing innovation beyond software and into all sorts of different areas," Jim Zemlin, executive director of the Linux Foundation said during his keynote address.

  • GitLab Inhales $268M Series E, Valuation Hits $2.75B

    GitLab raised a substantial $268 million in a Series E funding round that was more than doubled what the firm had raised across all of its previous funding rounds and pushed its valuation to $2.75 billion. It also bolsters the company’s coffers as it battles in an increasingly competitive DevOps space. GitLab CEO Sid Sijbrandij said in an email to SDxCentral that the new Series E funds will help the company continue to move on its goal of providing a single application to support quicker delivery of software. It claims more than 100,000 organizations use its platform. “These funds will help us to keep up with that pace and add to that with our company engineers,” Sijbrandij explained. “We need to make sure every part of GitLab is great and that CIOs and CTOs who supply the tools for their teams know that if they bet on GitLab that we’ll stand up to their expectations.”

  • How Chrome OS works upstream

    Google has a long and interesting history contributing to the upstream Linux kernel. With Chrome OS, Google has tried to learn from some of the mistakes of its past and is now working with the upstream Linux kernel as much as it can. In a session at the 2019 Open Source Summit North America, Google software engineer Doug Anderson detailed how and why Chrome OS developers work upstream. It is an effort intended to help the Linux community as well as Google. The Chrome OS kernel is at the core of Google's Chromebook devices, and is based on a Linux long-term support (LTS) kernel. Anderson explained that Google picks an LTS kernel every year and all devices produced in that year will use the selected kernel. At least once during a device's lifetime, Google expects to be able to "uprev" (switch to a newer kernel version). Anderson emphasized that if Google didn't upstream its own patches from the Chrome OS kernel, it would make the uprev process substantially more difficult. Simply saying that you'll work upstream and actually working upstream can be two different things. The process by which Chrome OS developers get their patches upstream is similar to how any other patches land in the mainline Linux kernel. What is a bit interesting is the organizational structure and process of how Google has tasked Chrome OS developers to work with upstream. Anderson explained that developers need to submit patches to the kernel mailing list and then be a little patient, giving some time for upstream to respond. A key challenge, however, is when there is no response from upstream. "When developing an upstream-first culture, the biggest problem anyone can face is silence," Anderson said. Anderson emphasized that when submitting a patch to the mailing list, what a developer is looking for is some kind of feedback; whether it's good or bad doesn't matter, but it does matter that someone cares enough to review it. What the Chrome OS team does in the event that there is no community review is it will have other Chrome OS engineers publicly review the patch. The risk and worry of having Chrome OS engineers comment on Chrome OS patches is that the whole process might look a little scripted and there could be the perception of some bias as well. Anderson noted that it is important that only honest feedback and review is given for a patch.

  • What's In A Name? Tales Of Python, Perl, And The GIMP

    In the older days of open source software, major projects tended to have their Benevolent Dictators For Life who made all the final decisions, and some mature projects still operate that way. Guido van Rossum famously called his language “Python” because he liked the British comics of the same name. That’s the sort of thing that only a single developer can get away with. However, in these modern times of GitHub, GitLab, and other collaboration platforms, community-driven decision making has become a more and more common phenomenon, shifting software development towards democracy. People begin to think of themselves as “Python programmers” or “GIMP users” and the name of the project fuses irrevocably with their identity. What happens when software projects fork, develop apart, or otherwise change significantly? Obviously, to prevent confusion, they get a new name, and all of those “Perl Monks” need to become “Raku Monks”. Needless to say, what should be a trivial detail — what we’ve all decided to call this pile of ones and zeros or language constructs — can become a big deal. Don’t believe us? Here are the stories of renaming Python, Perl, and the GIMP.

  • How to teach (yourself) computer programming

    Many fellow students are likely in the same boat, the only difference being that the vast majority not only that don’t list computer science as one of their passions (but more as one of their reasons for not wanting to live anymore), but they get a very distorted view of what computer science and programming actually is.

    Said CS classes tend to be kind of a joke, not only because of the curriculum. The main reason why they are bad and boring is the way they are taught. I am going to address my main frustrations on this matter together with proposed solutions and a guide for those who want to start learning alone.

  • [Old] Perl Is Still The Goddess For Text Manipulation

    You heard me. Freedom is the word here with Perl.

    Yes, Perl is fast. It’s lightening fast.
