  • Bat is Like the cat Command in Linux, But Super-Charged and Written in Rust

    Bat is a cat command clone with advance syntax highlighting for a large number of programming and markup languages.

    As you know, the cat (short for concatenate) command is a utility in Linux. One of its most commonly known usages is to print the content of a file onto the standard output stream. But given more time spent in the command line, features like syntax highlighting come in very handy.

  • How to configure your Raspberry Pi OS to use it for the first time - LinuxStoney

    Whether it is to set up a personal server, to play retro games, or simply out of curiosity and to learn programming, today we can all get a Raspberry Pi . This microcomputer has earned a great reputation within the IT sector thanks to its construction based on free hardware, the considerable power it offers and, above all, its price. We can install a wide variety of operating systems (especially Linux) on it. But, whatever system we install, we may have to make some configuration to adapt it to our needs. And here the problems can begin.

    Raspberry Pi OS is the official operating system for this microcomputer. This system is based on Debian, and it comes specially prepared and optimized to work in an optimized way on this device. However, depending on the use that we are going to give it, we may have to configure some aspect of it as soon as we start it up.

    In this way, we find two ways to configure this Raspberry Pi OS to adapt it to our needs.

  • rpm2cpio utility fixed

    I downloaded a Fedora rpm file, and was unable to open it. Hmmm, we had this problem ages ago, see this blog post in 2011:
    https://bkhome.org/archive/blog2/201106/busybox-39rpm2cpio39-fails.html
    And a fix for Xarchive in 2018:
    https://bkhome.org/news/201812/fix-rpm-extraction-in-xarchive.html
    EasyOS has the busybox 'rpm2cpio' applet, and that is still broken. The 'exploderpm' script doesn't seem to work either.

Pumpkins, markets, and one bad Apple

Imagine your local farmers market: every Saturday the whole town comes together to purchase fresh and homemade goods, enjoy the entertainment, and find that there is always something for everyone. Whatever you need, you can find it here, and anyone can sign up to have their own little stand. It is a wonderful place, or so it seems. Now, imagine starting out as a pumpkin farmer, and you want to sell your pumpkins at this market. The market owner asks 30% of every pumpkin that you sell. It's steep, but the market owner -- we'll call him Mr. Apple -- owns all the markets in your area, so you have little choice. Let's continue this analogy and imagine that, since it is a little hard for you to make ends meet, you decide to tell your customers that they can come visit you at your farm to purchase pumpkins. Mr. Apple overhears and shuts your stand down. You explain that your business cannot be profitable this way, but the grumpy market owner says that you can either comply or find another place. At the end of your rope, you look for information about starting your own farmers market, but it seems Mr. Apple owns every building in town. In the midst of Apple announcing its new products, attention is drawn away from its ongoing battle to maintain its subjugation over users globally. The Netherlands’ Authority for Consumers and Markets (ACM) last month informed the U.S. technology giant of its decision that the rules around the in-app payment system are anticompetitive, making it the first antitrust regulator to conclude that the company has abused market power in the App Store. And while Apple is appealing this verdict, the European Union is charging the company with another antitrust claim concerning the App Store. Read more

Development version: GIMP 2.99.8 Released

GIMP 2.99.8 is our new development version, once again coming with a huge set of improvements. Read more Some early coverage:

  • GIMP 2.99.8 Released with Clone Tool Tweaks, Support for Windows Ink

    A new development version of GIMP is available to download and it carries some interesting new features. While this isn’t a new stable release — GIMP 2.10.28 is the most recent stable release (and the version you’ll find in Ubuntu 21.10’s archives) — the release of GIMP 2.99.8 is yet another brick in the road to the long-fabled GIMP 3.0 release.

Mozilla: Six-Year Moziversary, Thomas Park/Codepip, and Weak Response to Critics of Firefox Spyware

  • Chris H-C: Six-Year Moziversary

    I’ve been working at Mozilla for six years today. Wow. Okay, so what’s happened… I’ve been promoted to Staff Software Engineer. Georg and I’d been working on that before he left, and then, well *gestures at everything*. This means it doesn’t really _feel_ that different to be a Staff instead of a Senior since I’ve been operating at the latter level for over a year now, but the it’s nice that the title caught up. Next stop: well, actually, I think Staff’s a good place for now. Firefox On Glean did indeed take my entire 2020 at work, and did complete on time and on budget. Glean is now available to be used in Firefox Desktop.

  • Hacks.Mozilla.Org: Hacks Decoded: Thomas Park, Founder of Codepip

  • Mark Surman: Exploring better data stewardship at Mozilla [Ed: Mozilla fails to admit that spying on Firefox users is wrong; now it's misframing the criticism and responds to a straw man]

    Over the last few years, Mozilla has increasingly turned its attention to the question of ‘how we build more trustworthy AI?’ Data is at the core of this question. Who has our data? What are they using it for? Do they have my interests in mind, or only their own? Do I trust them? We decided earlier this year that ‘better data stewardship’ should be one of the three big areas of focus for our trustworthy AI work. One part of this focus is supporting the growing field of people working on data trusts, data cooperatives and other efforts to build trust and shift power dynamics around data. In partnership with Luminate and Siegel, we launched the Mozilla Data Futures Lab in March as a way to drive this part of the work.
