  • Snapcraft Clinic Successes

    On Thursday I mentioned we were restarting the Snapcraft Clinic. Basically we stand up a regular video call with engineers from the snap and snapcraft team & us from Snap Advocacy. Developers of applications and publishers of snaps are invited to join to troubleshoot. There was nothing especially secret or private discussed, but as we don’t record or stream the calls, and I don’t have direct permission to mention the applications or people involved, so I’ll keep this a little vague. In future I think we should ask permission and record the outcomes of the calls. We had a few productive discussions. One developer brought an application which they’d requested classic confinement for, and wished to discuss the options for confinement. We had a rather lengthy open discussion about the appropriateness of the available options. The developer was offered some choices, including making changes to their application to accomodate confinement, and another was (as always) not to snap the application. They appreciated our openness in terms of accepting that there are limitations with all software, and not everything always makes sense to be packaged as a snap, at the moment. We also had a productive discusison with a representative of a group responsible for publishing multiple snaps. They had difficulties with a graphical snapped application once it had been updated to use core20. The application would launch and almost immediately segfault. As the application was already published in the Snap Store, in a non-stable channel, we were all able to install it to test on our own systems.

    Ich freue mich, heute das Release Version 0.96 von Kraft herauszugeben. Die neue Version kann über die Homepage heruntergeladen werden.

  • A new data format has landed in the upcoming GTG 0.5

    Diego’s changes are major, invasive technological changes, and they would benefit from extensive testing by everybody with “real data” before 0.5 happens (very soon). I’ve done some pretty extensive testing & bug reporting in the last few months; Diego fixed all the issues I’ve reported so far, so I’ve pretty much run out of serious bugs now, as only a few remain targetted to the 0.5 milestone… But I’m only human, and it is possible that issues might remain, even after my troll-testing. Grab GTG’s git version ASAP, with a copy of your real data (for extra caution, and also because we want you to test with real data); see the instructions in the README, including the “Where is my user data and config stored?” section. Please torture-test it to make sure everything is working properly, and report issues you may find (if any). Look for anything that might seem broken “compared to 0.4”, incorrect task parenting/associations, incorrect tagging, broken content, etc.

  • Notes on Addressing Supply Chain Vulnerabilities

    One of the unsung achievements of modern software development is the degree to which it has become componentized: not that long ago, when you wanted to write a piece of software you had to write pretty much the whole thing using whatever tools were provided by the language you were writing in, maybe with a few specialized libraries like OpenSSL. No longer. The combination of newer languages, Open Source development and easy-to-use package management systems like JavaScript’s npm or Rust’s Cargo/crates.io has revolutionized how people write software, making it standard practice to pull in third party libraries even for the simplest tasks; it’s not at all uncommon for programs to depend on hundreds or thousands of third party packages. [...] Even packages which are well maintained and have good development practices routinely have vulnerabilities. For example, Firefox recently released a new version that fixed a vulnerability in the popular ANGLE graphics engine, which is maintained by Google. Both Mozilla and Google follow the practices that this blog post recommends, but it’s just the case that people make mistakes. To (possibly mis)quote Steve Bellovin, “Software has bugs. Security-relevant software has security-relevant bugs”. So, while these practices are important to reduce the risk of vulnerabilities, we know they can’t eliminate them. Of course this applies to inadvertant vulnerabilities, but what about malicious actors (though note that Brewer et al. observe that “Taking a step back, although supply-chain attacks are a risk, the vast majority of vulnerabilities are mundane and unintentional—honest errors made by well-intentioned developers.”)? It’s possible that some of their proposed changes (in particular forbidding anonymous authors) might have an impact here, but it’s really hard to see how this is actionable. What’s the standard for not being anonymous? That you have an e-mail address? A Web page? A DUNS number?[3] None of these seem particularly difficult for a dedicated attacker to fake and of course the more strict you make the requirements the more it’s a burden for the (vast majority) of legitimate developers. I do want to acknowledge at this point that Brewer et al. clearly state that multiple layers of protection needed and that it’s necessary to have robust mechanisms for handling vulnerability defenses. I agree with all that, I’m just less certain about this particular piece.

  • The HTTP Referer header is fading away (at least as a useful thing)

    The HTTP Referer header on requests is famously misspelled (it should be Referrer), and also famously not liked because of privacy and security concerns. The privacy and security concerns are especially strong with external ('cross-origin') Referers, which is also the ones that many people find most useful because they tell you where visitors to your pages are coming from and let you find places where people have linked to you or are mentioning you.

  • horizonator: terrain renderer based on SRTM DEMs

    I just resurrected and cleaned up an old tool I had lying around. It's now nice and usable by others. This tool loads terrain data, and renders it from the ground, simulating what a human or a camera would see. This is useful for armchair exploring or for identifying peaks. This was relatively novel when I wrote it >10 years ago, but there are a number of similar tools in existence now. This implementation is still useful in that it's freely licensed and contains APIs, so fancier processing can be performed on its output.

  • Happy birthday, Python, you're 30 years old this week: Easy to learn, and the right tool at the right time

    The 30th anniversary of Python this week finds the programming language at the top of its game, but not without challenges. "I do believe that Python just doesn’t have the right priorities these days," said Armin Ronacher, director of engineering at software monitoring biz Sentry and creator of Flask, the popular Python web app framework, in an email interview with The Register. Ronacher, a prolific Python contributor, remains a fan of the language. He credits Python's success to being both easy to learn and having an implementation that was easy to hack. And in its early years, Python didn't have a lot of competitors with those same characteristics, he said.

  • How To Add Route on Linux – devconnected

    As a network engineer, you probably spend a lot of time thinking and planning your network infrastructure. You plan how computers will be linked, physically using specific cables but also logically using routing tables. When your network plan is built, you will have to implement every single link that you theorized on paper. In some cases, if you are using Linux computers, you may have to add some routes in order to link it to other networks in your company. Adding routes on Linux is extremely simple and costless : you can use the Network Manager daemon (if you are running a recent distribution) or the ifconfig one. In this tutorial, you will learn how you can easily add new routes on a Linux machine in order to link it to your physical network.

  • syncing subtitles in freedom

    The topic of creating subtitles with Free Software has often come up in my circles of Emacs-oriented users, and I haven't had a good recommendation to share, until this idea hit me the other day. Subtitle files are largely blocks of start/end time associated with blocks of text. I figured, once you got a transcript, existing Emacs Org Mode features could be used, perhaps along with keyboard macros, to turn the transcript into a synced subtitle file.

  • How To Install Minecraft on Ubuntu 20.04 LTS [Ed: Proprietary and Microsoft; not an attractive option as Free/libre alternatives exist]

    In this tutorial, we will show you how to install Minecraft on Ubuntu 20.04 LTS. For those of you who didn’t know, Minecraft is the most popular sandbox video game developed by Mojang studios but later purchased by Microsoft. It can be used with all major platforms like Linux, macOS, and Windows. Most Minecraft players would agree that the secrete to the game’s success lies in its creativity-inspiring design. Players are free to explore a large, procedurally generated world made of blocks, each of which can be interacted with, moved, or transformed into resources for crafting. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step-by-step installation of Minecraft on Ubuntu 20.04 (Focal Fossa). You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian-based distribution like Linux Mint.
