    • It's FOSS"Meet the Techs of Tomorrow Where They Are Today": A Conversation With Stu Keroff

      I remember reading an article about Linux back in (maybe) 1998 or 1999, and I was fascinated by it, but I didn’t actually try it for the first time until late 2005.

      I obtained a used computer from a tech friend and started experimenting with it. My first distros were Linspire and Mepis. From there, I moved to Ubuntu. At first, it was just having fun and learning how to make things work. Then, I started trying to do more of my teaching work using Linux. Then, it was getting students interested and involved.

      I first started doing Linux clubs at school back in 2012, and the whole thing started by accident. Our school had started a 1:1 laptop program that year, and almost immediately students started breaking and losing laptops. I wanted to integrate tech into my teaching, but I would have students in each class that did not have a laptop because they had broken it.

        I attended FOSSASIA 2023 summit held at Lifelong Learning Institute, Singapore. A 3 day long parallel talk filled conference. Its my second time attending FOSSASIA. The first one was 2018 summit. Like last time, I didn’t attend much talks but focussed on networking with people. A lot of familiar faces there. PV Anthony, Harish, etc.

        I vounteered to run Debian Booth at the exhibition hall distributing stickers, flyers. Rajudev also helped me at the booth. Most of the people there used debian or its derivates or know debian already, its easier for me that way, that I don’t have do much explaining compared to other booths. Thanks to Parth for looking after booth in my breaks.

      • GNUGnuastro 0.20 released

        Dear all,

        I am happy to announce the 20th stable version of Gnuastro: version 0.20.

        Gnuastro is an official GNU package, consisting of various command-line programs, C/C++ library functions and Makefile extensions for the manipulation and analysis of (astronomical) data. All the programs share the same basic command-line user interface (modeled on GNU Coreutils). For the full list of Gnuastro's library, programs, and several comprehensive tutorials (recommended place to start using Gnuastro), please see the links below respectively:

        https://www.gnu.org/s/gnuastro/manual/html_node/Gnuastro-library.html https://www.gnu.org/s/gnuastro/manual/html_node/Gnuastro-programs-list.html https://www.gnu.org/software/gnuastro/manual/html_node/Tutorials.html

        In the 27 weeks since 0.19, there have been 122 commits by 12 people with 15265 lines of code and documentation inserted and 5779 deleted. See [1] for the list of people who contributed for all the exciting new features that have been added (thanks a lot everyone!). For the full list of added and changed features, as well as the fixed bugs, please see [2].

        Here is the compressed source and the GPG detached signature for this release. To uncompress Lzip tarballs, see [3]. To check the validity of the tarballs using the GPG detached signature (*.sig) see [4]. See [5] for the list of software used to bootstrap this tarball.

          PyTest is a popular testing framework for Python programming language. Fixtures in PyTest provide a way to manage the resources and data required for running tests. They simplify the process of setting up, tearing down, and sharing test data between test functions. PyTest fixtures provide a convenient way to define these resources and data once and reuse them across multiple tests, saving time and reducing the chance of errors.

          In this tutorial, you will learn what PyTest fixtures are, why they are used, and how to define and use them in your tests. To explore the usage of Pytest fixtures, you’ll be creating a simple note-taking application that lets users add, edit, and get notes.

        • Enrico Zini: Gkt4 model-backed radio button in Python

          Gtk4 has interesting ways of splitting models and views. One that I didn't find very well documented, especially for Python bindings, is a set of radio buttons backed by a common model.

          The idea is to define an action that takes a string as a state. Each radio button is assigned a string matching one of the possible states, and when the state of the backend action is changed, the radio buttons are automatically updated.

          All the examples below use a string for a value type, but anything can be used that fits into a GLib.Variant.

      One of my favourite parts of travelling to a destination by plane -- and indeed train -- is to play an available piano. I find playing piano relaxing, a way for me to take a break from thinking about all of the details of my journey. With that said, there are many airports without pianos, and many more that have one piano in a single terminal but no pianos in other terminals. I was speaking with a few people about how we could help place pianos in airports where one is not available, providing travellers with the ability to have the same experience I and many other travellers have: a moment to sit back and make music between legs of a journey.

        In 2017, as lawyers for prisoners in Ohio sought to spare their clients from lethal injection, they challenged one of the state’s key witnesses: Daniel Buffington.

        As he had done elsewhere, the Florida-based pharmacist had submitted written testimony saying that prisoners would not feel pain from the three-drug cocktail administered by executioners. But the lawyers for the men on death row argued that Buffington was unqualified to testify in an upcoming hearing, noting that he had not administered general anesthesia or conducted research on midazolam, the key sedative in the execution protocol.

      • Pro PublicaA Pharmacist Is Helping Clear the Way for Lethal Injections

        Last winter, Dr. Gail Van Norman sat on the witness stand in the federal courthouse in Oklahoma City, testifying as part of a trial that would determine whether Oklahoma’s lethal injection procedure was constitutional. Two weeks earlier, at the request of lawyers representing more than two dozen prisoners, Van Norman, an anesthesiologist and professor at the University of Washington, had attended the execution of a man named Gilbert Ray Postelle.

        In the execution chamber, she testified, Postelle was lying face-up on a gurney with his arms stretched out beside him. Executioners injected him with midazolam, a drug that was supposed to knock him unconscious so he didn’t feel pain from two drugs that would soon paralyze him and stop his heart. It didn’t appear to work. For 2 1/2 minutes after receiving midazolam, Postelle continued to wiggle his hands and feet. His eyes remained open, blinking and looking up at the ceiling. Postelle’s breathing became increasingly strenuous and rapid. Van Norman said his trouble breathing was a result of the large dose of midazolam.

        Most ham radio operators will build an antenna of some sort when they first start listening or transmitting, whether it’s a simple dipole, a beam antenna like a Yagi, or even just a random wire vertical antenna. All of these will need to be connected feedline of some sort, and in the likely event you reach for some 50-ohm coax cable you’ll also need a balun to reduce noise or unwanted radiation. Don’t be afraid of extra expenses when getting into this hobby, though, as [W6NBC] demonstrates how to construct an “ugly balun” out of the coax wire itself (PDF).

        There is a security concern, as the password the user types in at bootup is used to create the encrypted folders. Quoting from here:

        https://www.kernel.org/doc/html/latest/filesystems/fscrypt.html

        Master keys must be real cryptographic keys, i.e. indistinguishable from random bytestrings of the same length. This implies that users must not directly use a password as a master key, zero-pad a shorter key, or repeat a shorter key. Security cannot be guaranteed if userspace makes any such error, as the cryptographic proofs and analysis would no longer apply.

      • Stronger cybersecurity, reducing cyber incidents, greater EU ‘strategic autonomy’? Three interesting features of the proposed EU Cyber Solidarity Act

        On April 18, 2023, the European Commission published its proposal for an EU Cyber Solidarity Act (“CSA”). It aims to strengthen incident detection, situational awareness, and response capabilities, and to ensure that entities providing services critical for day-to-day life can access expert support to manage their cyber risk and respond to incidents. Specifically, the CSA aims to promote information sharing about cyber incidents and vulnerabilities, to help improve the cyber resilience of critical entities, and to create an EU-wide resource for incident management.

        The CSA adds another layer to the increasingly crowded landscape of EU cybersecurity laws. The proposed law would interact with the revised Network and Information Security Directive (“NIS2”) and certifications issued under the Cybersecurity Act. Private companies in specific sectors will also have to consider potential overlap with the forthcoming Cyber Resilience Act and the financial services-focused Digital Operation Resilience Act.

        • uni StanfordThe STOP CSAM Act: An Anti-Encryption Stalking Horse

          E2EE’s growing ubiquity seems like a clear win for personal privacy, security, and safety, as well as national security and the economy. And yet E2EE’s popularity has its critics – including, unfortunately, Sen. Durbin. Because it’s harder for providers and law enforcement to detect malicious activity in encrypted environments than unencrypted ones (albeit not impossible, as I’ll discuss), law enforcement officials and lawmakers often demonize E2EE. But E2EE is a vital protection against crime and abuse, because it helps to protect people (children included) from the harms that happen when their personal information and private conversations fall into the wrong hands: data breaches, hacking, cybercrime, snooping by hostile foreign governments, stalkers and domestic abusers, and so on.

          That’s why it’s so important that national policy promote rather than dissuade the use of E2EE – and why it’s so disappointing that STOP CSAM has turned out to be just the opposite: yet another misguided effort by lawmakers in the name of online safety that would only make us all less safe.

In the nature of things, however, there will still be human disputes, and some of them will involve Muslims. Now that “Islamophobia” has been established as targeted by the government, these disputes will all be ascribed to “Islamophobia” and offered as evidence of how urgently needed this “interagency task force” really is. The “Islamophobia” task force will therefore likely enjoy ever-increasing budgets. That’s how government agencies work: they have to justify their existence, so they keep having to find more and more of the thing they’re supposed to be stamping out.

      Working through this book – and its two sequels, which travel back in time to the 1980s and Marty's first encounters with VisiCalc and Lotus 1-2-3 – I was struck by the similarities between spreadsheets and science fiction.

      While many people use spreadsheets as an overgrown calculator, adding up long columns of numbers, the rise and rise of spreadsheets comes from their use in modeling. Using a spreadsheet, a complex process can be expressed as a series of mathematical operations: we put these inputs into the factory and we get these finished goods. Once the model is built, we can easily test out contrafactuals: what if I add a third shift? What if I bargain harder for discounts on a key component?

      While we’ve been busily distracted on the big issues like cost of living, AUKUS, the Voice, access to doctors and a broken gas market, Prime Minister Anthony Albanese has been quietly wrapping a highly controversial topic in a Cabinet secrecy blanket. Rex Patrick looks at politicised government advertising and raises concerns about the new Government Communications Sub-Committee of Cabinet.

      • New Eastern EuropeCan we win the information war?

        MACIEJ MAKULSKI: I would like to start by asking you to paint a general picture of where we are regarding this information war and the counter-measures used to address this problem. We decided to go back into history a little and mark Russia’s war against Ukraine as a kind of breakthrough point, although we know that all kinds of lines are a bit artificial. But it was actually interesting for me to think about how before that we were rather discussing the problem of post-truth, which was a buzzword at that time, and after February 22nd 2022 I have an impression that a whole industry fighting disinformation has developed even more; that we are in a different place because the answer to the threats is more systemic, coherent and consistent. So, what I would like to ask you first is how you would characterise the position we are in right now and what major trends are worthy of discussion?

      • Garden Path

        Anyways there was a very green frog (Pseudacris regilla, probably) perched on a bag of bark, maybe because the area was in the shade and somewhat moist, being on the north side of the building. The other garden path here is "a grammatically correct sentence that starts in such a way that a reader's most likely interpretation will be incorrect" insofar as this is possible in lojban. Here a line break is used to trick the reader; we start off with "a green tree" but the next line gives a bo which joins the tree tighter to pipybanfi, so it's a (green (tree frog)) once you get to the second line, not the default ((green tree) frog) without the bo. Garden path sentences are really better done in not lojban, where you can usually play around with homonyms, verb nouns, or who knows what else to really cause the reader to stop and have to rethink the sentence.

        I very much agree with this sentiment. I like pico-8 in a lot of ways though, actually _because_ it's a very self-contained and quite simple system, but I've often thought it would have been a lot more fun if we'd just get to program in some sort of fantasy assembly. I would have loved to see an instruction set and architecture on such a machine that's very different from what we're used to on the likes of x86 and arm. That would have been so much fun.

        It's been awhile since I used the eeepc 701. It still does OK. Running antix v19.2 x86. It hasn't been updated in awhile, but I will probably do that when I connect to the network. I forgot that I don't like the keyboard on this device. It's cramped and I keep hitting the wrong keys. Also, not much light here. I've been spoiled by illuminated keyboards.

        The speaker repurposing from my last post was a success! I ended up crimping a mix of terminal and Posi-lock connectors to some speaker wires so I wouldn't have to solder anything. Yeah, I'm lazy and I could use the practice. Another time.

          A while back the Rust project switched from recommending the Rust Language Server (rls) to officially supporting it's replacement, rust-analyzer for use in IDE's and editors. There were solid technical reasons for the change, but the rollout was not without some growing pains.

          One issue with using an lsp server in the context of Rust is that it is common for people to have multiple versions of the Rust toolchain on their system. Most people who use Rust in anger have at least a stable toolchain and a nightly, while some projects (such as the Linux kernel) requiring a specific stable compiler version. It's not a problem due to the language changing that fast (although a few years ago it would have been). The issue is that in order to support procedural macros rust-analyzer must be built from the same source as the compiler in use. That means that one would need a version of the program for each toolchain, and a way to switch between them.
