  • Letter of Recommendation: Bug Fixes

    I wouldn’t expect a nonprogrammer to understand the above, but you can intuit some of what’s going on: that we don’t need ImageMagick to scale images anymore, because the text editor can scale images on its own; that it’s bad form to spell-check hex values, which specify colors; that the bell is doing something peculiar if someone holds down the alt key; and so forth.

    But there’s also something larger, more gladdening, about reading bug fixes.

    My text editor, Emacs, is a free software project with a history going back more than 40 years; the codebase itself starts in the 1980s, and as I write this there are 136,586 different commits that get you from then to now. More than 600 contributors have worked on it. I find those numbers magical: A huge, complex system that edits all kinds of files started from nothing and then, with nearly 140,000 documented human actions, arrived at its current state. It has leaders but no owner, and it will move along the path in which people take it. It’s the ship of Theseus in code form. I’ve probably used Emacs every day for more than two decades. It has changed me, too. It will outlive me.

    Open source is a movement, and even the charitably inclined would call it an extreme brofest. So there’s drama. People fight it out in comments, over everything from semicolons to codes of conduct. But in the end, the software works or it doesn’t. Politics, our personal health, our careers or lives in general — these do not provide a narrative of unalloyed progress. But software, dammit, can and does. It’s a pleasure to watch the code change and improve, and it’s also fascinating to see big companies, paid programmers and volunteers learning to work together (the Defense Department is way into open source) to make those changes and improvements. I read the change logs, and I think: Humans can do things.

  • The Top 17 Free and Open Source Network Monitoring Tools

    Choosing the right network monitoring solution for your enterprise is not easy.

  • Hedge-fund managers are overwhelmed by data, and they're turning to an unlikely source: random people on the internet

    Alternative data streams of satellite images and cellphone-location data are where managers are now digging for alpha, as new datasets are created every day. And hedge funds have been spending serious cash searching for those who can take all this information and quickly find the important pieces.

    Now, as margins shrink and returns are under the microscope, hedge funds are beginning to consider a cheaper, potentially more efficient way to crunch all this data: open-source platforms, where hundreds of thousands of people ranging from finance professionals to students, scientists, and developers worldwide scour datasets — and don't get paid unless they find something that a fund finds useful.

  • TD Ameritrade Is Taking Its First Steps Towards Major Open Source Contributions

    STUMPY is a python library to identify the patterns and anomalies in time series data. STUMPY has benefited from open source as a means to shorten development roadmaps since the early 2000s and it represents a new opportunity for TD Ameritrade to give back to the developer community.

  • The Future of Open Source Big Data Platforms

    Three well-funded startups – Cloudera Inc., Hortonworks Inc., and MapR Technologies Inc. — emerged a decade ago to commercialize products and services in the open-source ecosystem around Hadoop, a popular software framework for processing huge amounts of data. The hype peaked in early 2014 when Cloudera raised a massive $900 million funding round, valuing it at $4.1 billion.

  • No Easy Way Forward For Commercial Open Source Software Vendors

    While still a student in 1995, Kimball developed the first version of GNU Image Manipulation Program (GIMP) as a class project, along with Peter Mattis. Later on as a Google engineer, he worked on a new version of the Google File System, and the Google Servlet Engine. In 2012, Kimball, Mattis, and Brian McGinnis launched the company Viewfinder, later selling it to Square.

  • 6 Reasons Why Developers Should Contribute More To Open Source

    Even by fixing minor things like a bug in a library or writing a piece of documentation can also help the developers to write readable or maintainable code. They can independently suggest to the community and generally tend to stick by the rules of writing a code that is easy to understand. The fact that the code will be exposed to everyone naturally makes them write focus on making it readable.

  • WIDE Project, KDDI develop router with open-source software, 3.2T-packet transmission

    The WIDE Project has adopted a router developed by Japanese operator KDDI. The router runs open-source software, and will be used with the networks operated and managed by the WIDE Project. The router will use open-source software with up to 3.2T-packet transmission.

    For this project, KDDI plans to start tests this month to verify the practical utility and interoperability of these routers when put to use in the actual service environment. The WIDE Project will be in charge of network administration and definition of requirements for router implementation.

  • Lack of progress in open source adoption hindering global custody’s digitisation

    Custody industry is lagging behind the rest of the financial services sector for open source projects, according to industry experts.

  • TNF: Industry should be focusing on open source development

    According to O'Shea, open source and the community are helping firms to find and attract experienced technology talent “uber engineers”.

  • Google Open Sources TensorNetwork , A Library For Faster ML And Physics Tasks

    “Every evolving intelligence will eventually encounter certain very special ideas – e.g., about arithmetic, causal reasoning and economics–because these particular ideas are very much simpler than other ideas with similar uses,” said the AI maverick Marvin Minsky four decades ago.

    Mathematics as a tool to interpret nature’s most confounding problems from molecular biology to quantum mechanics has so far been successful. Though there aren’t any complete answers to these problems, the techniques within domain help throw some light on the obscure corners of reality.

  • Open source to become a ‘best practice’

    There are many magic rings in this world… and none of them should be used lightly. This is true.

    It is also true that organisations in every vertical are now having to work hard and find automation streams that they can digitise (on the road to *yawn* digital transformation, obviously) and start to apply AI and machine learning to.

    Another key truth lies in the amount of codified best practices that organisations now have the opportunity to lay down.

    One we can denote a particular set of workflows in a particular department (or team, or group, or any other collective) to be deemed to be as efficient as possible, then we can lay that process down as a best practice.

  • Linux Weekly Roundup #35

    Hello and welcome to this week's Linux Roundup and what a wonderful week we had! We have plenty of Linux Distro releases and LibreOffice 6.3 RC1. The Linux distros with releases this week are Q4OS 3.8, SparkyLinux 5.8, Mageia 7.1, ArcoLinux 19.07.11, Deepin 15.11, ArchBang 2107-beta, Bluestar 5.2.1, Slackel 7.2 "Openbox" and Endeavour OS 2019.07.15. I looked at most of these Linux Distros, links below, I will look at some of them in the new week and some I will unfortunately not have a look at, for download links and more, please visit distrowatch.com Well, this is this week's Linux Roundup, thank you so much for your time! Have a great week!

  • Full Circle Magazine: Full Circle Weekly News #140
  • Christopher Allan Webber: ActivityPub Conf 2019

    That's right! We're hosting the first ever ActivityPub Conf. It's immediately following Rebooting Web of Trust in Prague. There's no admission fee to attend. (Relatedly, the conference is kind of being done on the cheap, because it is being funded by organizers who are themselves barely funded.) The venue, however, is quite cool: it's at the DOX Centre for Contemporary Art, which is itself exploring the ways the digital world is affecting our lives. If you plan on attending (and maybe also speaking), you should get in your application soon (see the flier for details). We've never done one of these, and we have no idea what the response will be like, so this is going to be a smaller gathering (about 40 people). In some ways, it will be somewhere between a conference and a gathering of people-who-are-interested-in-activitypub. As said in the flier, by attending, you are agreeing to the code of conduct, so be sure to read that.

Sysadmin Appreciation Day, IBM and Fedora

  • Gift ideas for Sysadmin Appreciation Day

    Sysadmin Appreciation Day is coming up this Friday, July 26. To help honor sysadmins everywhere, we want you to share your best gift ideas. What would be the best way a team member or customer could show their appreciation for you? As a sysadmin, what was the best gift you've ever received? We asked our writers the same question, and here are their answers: "Whilst working in the Ubuntu community on Edubuntu, I took it upon myself to develop the startup/shutdown sound scheme, which became the default in Ubuntu for, from what I can understand, the next decade. Whilst people had a love-hate relationship with my sound scheme, and rightly so, I had a love-hate relationship with my sound card during the development. At the time I had recorded all my sound samples using one sample rate, but my new sound card, as my motherboard had exploded a few days earlier, did not support it. I had two choices, resample all my samples (which I didn't really want to do) or buy a new sound card.

  • Red Hat OpenStack Platform with Red Hat Ceph Storage: Radosbench baseline performance evaluation

    Red Hat Ceph Storage is popular storage for Red Hat OpenStack Platform. Customers around the world run their hyperscale, production workloads on Red Hat Ceph Storage and Red Hat OpenStack Platform. This is driven by the high level of integration between Ceph storage and OpenStack private cloud platforms. With each release of both platforms, the level of integration has grown and performance and automation has increased. As the customer's storage and compute needs for footprints have grown, we have seen more interest towards running compute and storage as one unit and providing a hyperconverged infrastructure (HCI) layer based on OpenStack and Ceph. [...] Continuing the benchmarking series, in the next post you’ll learn performance insights of running multi-instance MySQL database on Red Hat OpenStack Platform and Red Hat Ceph Storage across decoupled and hyperconverged architectures. We’ll also compare results from a near-equal environment backed by all-flash cluster nodes.

  • The State of Java in Flathub

    For maintainers of Java-based applications in Flathub, it's worth noting that even if you consume the Latest OpenJDK extension in your application, users will not be broken by major updates because OpenJDK is bundled into your Flatpak. The implication of this for users is that they won't see updates to their Java version until the application maintainer rebuilds the application in Flathub. If you maintain a Java-based Flatpak application on Flathub, you can consume the latest version of your chosen OpenJDK stream (either LTS or Latest) simply by rebuilding; the latest version of that OpenJDK steam will be pulled in automatically.

  • Fedora Magazine: Contribute at the Fedora Test Week for kernel 5.2

    The kernel team is working on final integration for kernel 5.1. This version was just recently released, and will arrive soon in Fedora. This version has many security fixes included. As a result, the Fedora kernel and QA teams have organized a test week from Monday, Jul 22, 2019 through Monday, Jul 29, 2019. Refer to the wiki page for links to the test images you’ll need to participate. Read below for details.

Debian and Ubuntu Leftovers

  • Bootstrappable Debian BoF

    Greetings from DebConf 19 in Curitiba! Just a quick reminder that I will run a Bootstrappable Debian BoF on Tuesday 23rd, at 13.30 Brasilia time (which is 16.30 UTC, if I am not mistaken). If you are curious about bootstrappability in Debian, why do we want it and where we are right now, you are welcome to come in person if you are at DebCon or to follow the streaming.

  • Candy Tsai: Outreachy Week 6 – Week 7: Getting Code Merge

    You can’t overhear what others are doing or learn something about your colleagues through gossip over lunch break when working remotely. So after being stuck for quite a bit, terceiro suggested that we try pair programming. After our first remote pair programming session, I think there should be no difference in pair programming in person. We shared the same terminal, looked at the same code and discussed just like people standing side by side. Through our pair programming session, I found out that I had a bad habit. I didn’t run tests on my code that often, so when I had failing tests that didn’t fail before, I spent more time debugging than I should have. Pair programming gave insight to how others work and I think little improvements go a long way.

  • about your wiki page on I/O schedulers and BFQ
    Hi,
    this is basically to report outdated statements in your wiki page on
    I/O schedulers [1].
    
    The main problematic statement is that BFQ "...  is not ideal for
    devices with slow CPUs or high throughput I/O devices" because too
    heavy.  BFQ is definitely more sophisticated than any of the other I/O
    schedulers.  We have designed it that way to provide an incomparably
    better service quality, at a very low overhead.  As reported in [2],
    the execution time of BFQ on an old laptop CPU is 0.6 us per I/O
    event, against 0.2 us for mq-deadline (which is the lightest Linux I/O
    scheduler).
    
    To put these figures into context, BFQ proved to be so good for
    "devices with slow CPUs" that, e.g., Chromium OS migrated to BFQ a few
    months ago.  In particular, Google crew got convinced by a demo [3] I
    made for them, on one of the cheapest and slowest Chromebook on the
    market.  In the demo, a fast download is performed.  Without BFQ, the
    download makes the device completely unresponsive.  With BFQ, the
    device remains as responsive as if it was totally idle.
    
    As for the other part of the statement, "...  not ideal for ...  high
    throughput I/O devices", a few days ago I ran benchmarks (on Ubuntu)
    also with one of the fastest consumer-grade NVMe SSDs: a Samsung SSD
    970 PRO.  Results [4] can be summarized as follows.  Throughput with
    BFQ is about the same as with the other I/O schedulers (it couldn't be
    higher, because this kind of drives just wants the scheduler to stay
    as aside as possible, when it comes to throughput).  But, in the
    presence of writes as background workload, start-up times with BFQ are
    at least 16 times as low as with the other I/O schedulers.  In
    absolute terms, gnome-terminal starts in ~1.8 seconds with BFQ, while
    it takes at least 28.7 (!) seconds with the other I/O schedulers.
    Finally, only with BFQ, no frame gets lost in video-playing
    benchmarks.
    
    BFQ then provides other important benefits, such as from 5x to 10X
    throughput boost in multi-client server workloads [5].
    
    So, is there any chance that the outdated/wrong information on your
    wiki page [1] gets updated somehow?  If I may, I'd be glad to update
    it myself, after providing you with all the results you may ask.
    
    In addition, why doesn't Ubuntu too consider switching to BFQ as
    default I/O scheduler, for all drives that BFQ supports (namely all
    drives with a maximum speed not above ~500 KIOPS)?
    
    Looking forward to your feedback,
    Paolo
    
    
  • Should Ubuntu Use The BFQ I/O Scheduler?

    The BFQ I/O scheduler is working out fairly well these days as shown in our benchmarks. The Budget Fair Queueing scheduler supports both throughput and low-latency modes while working particularly well for consumer-grade hardware. Should the Ubuntu desktop be using BFQ by default? [...] But in addition to wanting to correct that Wiki information, Paolo pops the question of why doesn't Ubuntu switch to BFQ as the default I/O scheduler for supported drives. Though as of yet, no Ubuntu kernel developers have yet commented on the prospect of switching to BFQ.
