    • uni TorontoHow old our servers are (as of 2022)

      Back in 2016, I wrote about how old our servers were at the time. They were rather older than people might have expected, because universities are generally cheap and so usually run servers much longer than many people do. My group no longer quite runs servers into the ground, but we still can come close. Today, for reasons beyond the scope of this entry, I’m going to do a 2022 version of my old entry.

      My group only handles general departmental infrastructure on the non-undergraduate side of things, although these days we have some big servers that are mostly in our compute cluster. However, most of the most modern and powerful servers are in research groups, and get turned over much faster than we do (in fact we just recently got rid of some vintage 2011 ‘compute’ servers we inherited that way).

      Our normal servers remain almost entirely 1U Dell servers, although we’ve wound up with some ultra-short Supermicro servers as well that we use for firewalls. What we consider our current generation of Dell 1U servers are R340s and R240s; these are what we use for new installs of machines that we particularly care about. Since we’re in the process of upgrading a bunch of machines from Ubuntu 18.04 to 22.04, the number of these servers in production use is likely to go up. Somewhat older than that are Dell R230s, which it looks like we started using in 2017 or maybe 2018, and then we have quite a number of R210 IIs and R310s still in service, although we’re rotating those out of service as we upgrade machines to Ubuntu 22.04. We’re still reusing some of these old Dells for test servers or unimportant things, although we’ve decided that a number of them have CPUs that are now just too slow for modern Linux.

    • Ruben SchadeThinking aloud about web engagement

      Last Wednesday I talked about the growing trend of superficial Linux distro reviews, both on YouTube and in thousands of cookie-cutter websites. Michael Dexter has lamented the fact that site wrapping software announcement with ads places higher in search results than the announcements themselves.

      I have intimate experience with this. Software and writing I once published under my (now retired) alias would routinely get picked up and disseminated, usually without attribution. My primary blog here is now big and old enough that its harder to get away with this, but I still find people wrapping my words wholesale so they can get cents of ad revenue. I still continue to publish full articles in my RSS feeds, but I’m starting to understand why others only want to include summaries.

      [...]

      As I said in that Linux desktop review post, I don’t think everyone is guilty of this. But it does go part of the way to explain why we’re seeing so many more of these mass-farmed videos and blogs, all saying broadly the same thing. Substance has been replaced with SEO (an abbreviation I’ve long thought a red herring), quality with quantity, and search engines like Google are, at best, enablers. There’s a reason everyone thinks search results aren’t as good now as they used to be.

      [...]

      The web seems to be cleaving in two directions: rubbish, and paywalls. I’d guess there are just as many people sharing knowledge, experience, and ideas as ever before, but they’re being drowned out by an increasing tide of churnalism, theft, and low-effort spam. Sandy demonstrates as much when doing some basic geographic and health searches in the first linked post, some of which has already cost lives.

        Some of you may already know that I’m operating an XMPP server. So far there are several domains running on that XMPP server and two domains are open for public registration. Namely these domains are hookipa.net and xmpp.social. You can find the service under the main domain on https://hookipa.net.

        Interesting in this is, that for some time xmpp.social seemed to be the domain of choice for many users, maybe because of “xmpp” and “social” in the domain name – or because it is easier to name it than “hookipa” with “double-oh” and “kay”… who knows…

        Reading expands the mind, but sometimes, pulling a 600-page tome from your pocket just isn’t practical. You can’t indulge in classic prose when driving a car, for example. This is where audiobooks come in, giving you the benefit of a narrated literary experience without requiring that you take your eyes off the road. With audiobooks, you can consume fantastic literature while driving, doing the dishes or even while you’re working.

        While there are numerous audiobook subscription services available, it’s far more satisfying to create and host your own library on a Raspberry Pi.

      • DebugPointHow to Apply Accent Colour in Ubuntu Desktop

        It’s easy to apply accent colour on Ubuntu desktop, thanks to recent developments. Here’s how.

        Every Linux distribution has its default theme, bringing a dominant colour. The Accent colours are used to highlight the dominant colour in any setup. Generally, the primary and Accent colours should contrast or complement each other.

        With the recent revamp of the GNOME desktop, the Ubuntu desktop introduced Accent colour in the Ubuntu 22.04 LTS release.

        Since it’s pretty obvious how to apply it, but for the sake of new buds in Linux, I will explain how to use Accent colour on an Ubuntu desktop.

      • ByteXDHow to Install Nvidia Drivers on Fedora Linux 34/35 – ByteXD

        Fedora comes with an open-source NVIDIA driver. The driver installed is Nouveau, an open-source graphics driver for NVIDIA video cards.

        However, Nouveau drivers are considered slower than Nvidia’s proprietary drivers. This won’t matter much if you only use your device for light use, but if you are into design or gaming, you’ll surely start to feel it – in this case it would be a good choice to install the latest NVIDIA drivers.

        In this tutorial we’ll be installing the latest NVIDIA drivers on Fedora 34/35 using the RPM Fusion repositories and also through the manual method of downloading the driver from the Nvidia website.

      • ID RootHow To Install Timeshift on Ubuntu 22.04 LTS – idroot

        In this tutorial, we will show you how to install Timeshift on Ubuntu 22.04 LTS. For those of you who didn’t know, Timeshift is software that provides a function similar to System Restore on Windows or Time machine on macOS. Timeshift protects your system by taking incremental snapshots of the file system at regular intervals. These snapshots can be restored at a later date to undo all changes to the system.

        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 the step-by-step installation of the Timeshift restore or backup tool on Ubuntu 22.04 (Jammy Jellyfish). You can follow the same instructions for Ubuntu 22.04 and any other Debian-based distribution like Linux Mint, Elementary OS, Pop!_OS, and more as well.

        Steam software is the largest online distribution platform for computer games and is available for Windows, Linux, and macOS. Steam comes from developer Valve and has more than 100 million active users.

        The online platform Steam is ostensibly a distribution platform for software, PC games, and series or movies. The platform is developed by the company Valve and has several million active accounts, according to its information

        Even though it is available for Linux, that doesn’t mean all the games available on it can be played on Linux Distros. Only games that are originally published by the developers with Linux support can be. Yes, indeed as compared to Windows the numbers of the games are not much for Ubuntu or other Linux distributions but whatever is there yet a good source to satisfy the binge of gaming on open source platforms. The games are protected with DRM.

      • ArduinoReading analog gauges with the Nicla Vision | Arduino Blog

        Analog instruments are everywhere and used to measure pressure, temperature, power levels, and much more. Due to the advent of digital sensors, many of these became quickly obsolete, leaving the remaining ones to require either conversions to a digital format or frequent human monitoring. However, the Zalmotek team has come up with a solution that incorporates embedded machine learning and computer vision in order to autonomously read these values.

        Mounted inside of a custom enclosure, their project relies on an Arduino Pro Nicla Vision board, which takes periodic images for further processing and inference. They began by generating a series of synthetic gauge pictures that have the dial at various positions, and labeled them either low, normal, or high. This collection was then imported into the Edge Impulse Studio and used to train a machine learning model on the 96x96px samples due to the limited memory. Once created, the neural network could successfully determine the gauge’s state about 92% of the time.

      • ArduinoThis snake robot is large enough to ride upon | Arduino Blog

        If a robot is rideable, is it still a robot or is it a vehicle? We would argue that if it rolls on standard automobile-style wheels or even tank tracks, it is a vehicle. But James Bruton’s eight-wheeled robot snake bike is quite clearly something else. This “vehicle” started as a small functional model that everyone would call a robot. Now Bruton has finished the full-size rideable snake robot and it is something to behold.

        The robot consists of four caterpillar-like segments, each with a pair of wheels. Two of the segments have driven wheels, while the other two segments have free wheels. Each segment is able to pivot relative to its neighbor and can also tilt up/down. There are two reasons for the tilt actuation. The first is to compensate for the rider’s weight in order to keep all of the wheels on the ground. The second reason is to handle bumps and uneven terrain, similar to a car’s suspension. The rider sits on a motorcycle seat mounted to the third segment (which is driven), so their weight is roughly centered.

      • Linux Links6 Top Free and Open Source Groovy Web Frameworks – LinuxLinks

        One of the types of software that’s important for a web developer is the web framework. A framework “is a code library that makes a developer’s life easier when building reliable, scalable, and maintainable web applications” by providing reusable code or extensions for common operations. By saving development time, developers can concentrate on application logic rather than mundane elements.

        A web framework offers the developer a choice about how to solve a specific problem. By using a framework, a developer lets the framework control portions of their application. While it’s perfectly possible to code a web application without using a framework, it’s more practical to use one.

        Groovy is a powerful, optionally typed and dynamic language, with static-typing and static compilation capabilities, for the Java platform aimed at improving developer productivity thanks to a concise, familiar and easy to learn syntax.

      • uni TorontoThe pervasive effects of C’s malloc() and free() on C APIs

        If this structure is dynamically allocated by gethostbyname() and returned to the caller, either you need an additional API function to free it or you have to commit to what fields in the structure have to be freed separately, and how (ie, this is part of the API). Having the caller free things is also not all that simple. Since this structure contains embedded pointers (including two that point to arrays of pointers), there could be quite a lot of things for the caller to call free() on (and in the right order).

        This issue isn’t unique to gethostbyname(); it affects any C API that wants to return (in a conceptual sense) anything more complicated than a basic type or a simple structure (even in old C, simple structures can be ‘returned’ by passing a pointer to the structure to the function, as is done in stat()). C offers no good solution to the problem; either you add one or more ‘free’ functions to your API (one per dynamically allocated structure you’re returning), or you document and thus freeze the process for freeing what you return, or you do what BSD opted to in gethostbyname() and return a pointer to something static.

        (Documenting what callers have to free implies that you can’t later add extra fields to what you return unless they don’t have to be freed separately.)

      • Jussi PakkanenJussi Pakkanen: Making decision without all the information is tricky, a case study

        In a recent blog post, Michal Catanzaro wrote about choosing proper configurations for your build, especially the buildtype attribute. As noted in the text, Meson’s build type setup is not the greatest in the world., so I figured I’d write why that is, what would a better design look like and why we don’t use that (and probably won’t for the foreseeable future).

        The concept of build types was copied almost directly from CMake. The main thing that they do is to set compiler flags like -g and -O2. Quite early in the development process of Meson I planned on adding top level options for debug info and optimization but the actual implementation for those was done much later. I copied the build types and flags almost directly except for build types RelWithDebInfo and Release. Having these two as separate build types did not make sense to me, because you always need debug info for releases. If you don’t have it, you can’t debug crash dumps coming from users. Thus I renamed them to debugoptimized and release.

        So far so good, except there was one major piece of information I was missing. The word “debug” has two different meaning. On most platforms it means “debug info” but on Windows (or, specifically, with the MSVC toolchain) “debug” means a special build type that uses the “debug runtime” that has additional runtime checks that are useful during development. More info can be found e.g. here. This made the word “debug” doubly problematic. Not only do people on Windows want it to refer to the debug runtime but then some (but not all) people on Linux think that “debugoptimized” means that it should only be used during development. Originally that was not the case, it was supposed to mean “build a binary with the default optimizations and debug info”. What I originally wanted was that distros would build packages with buildtype set to debugoptimized as opposed to living in the roaring 90s, passing a random collection of flags via CFLAGS and hoping for the best.

        As some of you guessed already, analytically figuring out percentiles for anything but a trivial queueing system is difficult.

      • The Surprising Way Crowd Size Affects Our Tendency to Cheat

        That’s the lesson from new research by Maryam Kouchaki, a professor of management and organizations at the Kellogg School. Across several experiments, Kouchaki and her coauthors—Celia Chui of HEC Montreal and Francesca Gino of Harvard Business School—found that people cheat at higher rates in larger groups.

        Why? The researchers found an intriguing self-fulfilling prophecy at work: people expect there to be higher numbers of cheaters within larger groups. This perception, in turn, increases the sense that cheating is common and therefore acceptable.
        The study illustrates the importance of context and social norms in determining whether or not we behave ethically. After all, we don’t magically transform from saints in groups of five to sinners in groups of 100. Rather, we unconsciously cue off other people and what we expect their behavior to be.

        “When you think your behavior is normative,” Kouchaki explains, “then it seems more defensible. Questionable behavior seems more justifiable when you think more people are doing it.”

        I had reason to port forward through my home router’s NAT to our bhyve box this weekend. There are some updates to Minecraft and Plex, and I wanted to do my Sunday maintenance from a coffee shop over SSH, like a gentleman.

        Before I left, I opened the requisite port and enabled the port forward on the router. I tested it from an external IP and… nothing. I rebooted it to confirm the setting was correct and had been committed… still nothing. OpenSSH dutifully timed out each time.

        I was in a hurry and couldn’t be bothered doing a port scan or any further troubleshooting, so I opened a remote SSH tunnel to my external jump box and left.

        You know the saying that the cobbler’s son walks barefoot? Well we use the crappy home router our ISP gave us when we moved; albeit one I keep regularly patched. Its Wi-Fi range is more than sufficient for our tiny apartment, and I haven’t ever been bothered to replace it because if it ain’t broke, don’t fix it. But the fact I couldn’t get a console up or even do basic troubleshooting in a pinch may be enough to convince me otherwise.

      • Scientific AmericanHow Humans’ Ability to Digest Milk Evolved from Famine and Disease

        The dawn of dairy farming in Europe occurred thousands of years before most people evolved the ability to drink milk as adults without becoming ill. Now researchers think they know why: lactose tolerance was beneficial enough to influence evolution only during occasional episodes of famine and disease, explaining why it took thousands of years for the trait to become widespread.

        The theory — backed up by an analysis of thousands of pottery shards and hundreds of ancient human genomes as well as sophisticated modelling — explains how the ability to digest milk became so common in modern Europeans, despite being almost non-existent in early dairy farmers. This ability, known as lactase persistence, comes from an enzyme that breaks down milk sugar and usually shuts down after young children are weaned.

      • GoogleGoogle Online Security Blog: Making Linux Kernel Exploit Cooking Harder

        The Linux kernel is a key component for the security of the Internet. Google uses Linux in almost everything, from the computers our employees use, to the products people around the world use daily like Chromebooks, Android on phones, cars, and TVs, and workloads on Google Cloud. Because of this, we have heavily invested in Linux’s security – and today, we’re announcing how we’re building on those investments and increasing our rewards.

        In 2020, we launched an open-source Kubernetes-based Capture-the-Flag (CTF) project called, kCTF. The kCTF Vulnerability Rewards Program (VRP) lets researchers connect to our Google Kubernetes Engine (GKE) instances, and if they can hack it, they get a flag, and are potentially rewarded. All of GKE and its dependencies are in scope, but every flag caught so far has been a container breakout through a Linux kernel vulnerability. We’ve learned that finding and exploiting heap memory corruption vulnerabilities in the Linux kernel could be made a lot harder. Unfortunately, security mitigations are often hard to quantify, however, we think we’ve found a way to do so concretely going forward.

        Simply finding vulnerabilities and patching them “is totally useless,” according to Google’s Eduardo Vela, who heads the cloud giant’s product security response team.

        To this end, Google’s open-source, Kubernetes-based Capture-the-Flag (kCTF) project doesn’t pay researchers a bounty to just find a Linux Kernel vulnerability. Instead, they’ve got to exploit the bug: connect to Google Kubernetes Engine (GKE) instances, hack it, and use the bug to steal the hidden flags.

          On 29 September 2020, a masked man entered a branch of the Wells Fargo bank in Washington, D.C., and handed the teller a note: “This is a robbery. Act calm give me all hundreds.” The teller complied. The man then fled the bank and jumped into a gray Tesla Model S. This was one of three bank robberies the man attempted the same day.

          When FBI agents began investigating, they reviewed Washington, D.C.’s District Department of Transportation camera footage, and spotted a Tesla matching the getaway vehicle’s description. The license plate on that car showed that it was registered to Exelorate Enterprises LLC, the parent company of Steer EV—a D.C.-based monthly vehicle-subscription service.

          Agents served a subpoena on Steer EV for the renter’s billing and contact details. Steer EV provided those—and also voluntarily supplied historical GPS data for the vehicle. The data showed the car driving between, and parking at, each bank at the time of the heists. The renter was arrested and, in September, sentenced to four years in prison.

      • The ConversationHow Patrice Lumumba’s assassination drove student activism, shaping the Congo’s future

        During a recent visit to the Democratic Republic of Congo (DRC), King Philippe of Belgium made a speech to the national parliament in Kinshasa expressing his “deepest regrets” for the exploitation and oppression of Belgian colonialism.

        The European nation ruled the Democratic Republic of Congo from 1908 until 1960. Before that it had been a personal colony of Leopold II, Philippe’s great great grand uncle, for more than 25 years.

        [...]

        While Belgium has partly acknowledged its responsibility for the murder, no protagonists have been brought to justice. A parliamentary commission found that King Baudouin, the monarch at Congo’s decolonisation, was aware of plans to assassinate Lumumba. However, Baudouin’s complicity remains to be officially recognised.

        The commission “tried in a way to limit the damages with its conclusions” and shied away from linking Belgium directly to the assassination. That was because “the diplomatic, ideological and financial consequences would be extremely great.”

        This might be why King Philippe is focusing on moving forward. His speech in Lubumbashi positioned Congolese students as a future-oriented group with whom Belgium could forge a new partnership.

        But there’s a crucial element missing from this logic: the specific role historically played by university students in further entrenching decolonisation in the Congo. This appeared most strongly during the 1960s.

      • Unchecked emissions could double heat-related child mortality

        If carbon emissions are limited to slow temperature rise, as many as 6,000 child deaths could be prevented in Africa each year, according to new estimates.

        A team of international scientists, led by the University of Leeds in collaboration with researchers at the London School of Hygiene & Tropical Medicine (LSHTM), have shown that thousands of heat-related child deaths could be prevented if temperature increases are limited to the Paris Agreement’s 1.5ºC target through to 2050.

        However, heat-related child deaths could double in sub-Saharan Africa by mid-century if high emissions continue.

        Their work, published in the journal Environmental Research Letters, estimated the impact of climate change on annual heat-related deaths of children under five in sub-Saharan Africa, from 1995 to 2050.

        • Michael West MediaAdam Bandt hung out to dry, in a solar-friendly way – Michael West

          It was a big day for the Albanese government on Wednesday when its 43% emissions reduction targets were guaranteed passage in the Senate. Announcing the news, Albanese and Energy Minister Chris Bowen were grinning from ear to ear.

          The uncertainty had come with the stance of the Greens. But their leader, Adam Bandt, confirmed the deal while giving his first address to the National Press Club since storming parliament with 16 members on May 21. Looking not exactly chuffed to be outlining a rare compromise, Bandt labelled Greens the only party of the centre-left. He rebranded Labor the party of the centre right, with the Coalition naturally corralled to the far right.

          Bandt’s threat to hold up Labor’s Budget bills raised the spectre of 1975 so he walked that back too. In summary, it was a performance brimming with fire and brimstone, tempered with pragmatism and memories of the Greens’ disastrous vote against Labor’s climate bill in 2009.
          The Q&A segment of Bandt’s address was still in progress when ABC News broke away to cover the announcement by Albanese and Bowen (Albowenese?) of the climate deal. ”It’s now very clear that our legislation will pass the parliament,” Bowen said, trying not to gloat.

      • Michael West MediaKidnapped: billionaires’ loophole swiftly abolished by Greens and Labor, finally – Michael West

        Under cover of climate debate, the Greens and Labor swiftly and smartly killed off a longstanding loophole which let Australian billionaires hide their financial affairs. Michael West reports on politicians beating the lobbyists.

        It was swift in the end, and silent. The “Billionaires’ Loophole” was abolished in a rapid act of Parliament yesterday amid the dramatic passage of Anthony Albanese’s climate bill, relegating 25 years of regulatory apartheid to Australian history, a period of one rule for the rich and powerful and another rule for the rest.

        We are talking about the “grandfathering” exemption, a loophole standing since 1995 which allowed Australia’s richest families of the time to hide their financial affairs.

        The Stokes, Pratts, Rineharts, Triguboffs and Lowys, Solomon Lew, Bob Ell, Marc Besen, and reclusive dynasties you’ve never heard of; all will now be subject to the same laws as everybody else. Even billionaire parvenus such as Andrew Forrest and Mike Cannon-Brookes, and multinational corporations too, are required to disclose their financial statements with the regulators. Not so, those on the “Secret Rich List”.

      • American Diplomacy as a Tragic Drama

        As in a Greek tragedy whose protagonist brings about precisely the fate that he has sought to avoid, the US/NATO confrontation with Russia in Ukraine is achieving just the opposite of America’s aim of preventing China, Russia and their allies from acting independently of U.S. control over their trade and investment policy. Naming China as America’s main long-term adversary, the Biden Administration’s plan was to split Russia away from China and then cripple China’s own military and economic viability. But the effect of American diplomacy has been to drive Russia and China together, joining with Iran, India and other allies. For the first time since the Bandung Conference of Non-Aligned Nations in 1955, a critical mass is able to be mutually self-sufficient to start the process of achieving independence from Dollar Diplomacy.

        For Ken Fairbanks, CEO of Insteon Technologies Inc., the last 60 days have been a rush to find office equipment, reestablish supplier relationships and figure out who his customers are. The former Insteon employee turned business consultant purchased the assets of SmartLab Inc. through a unique process that has left him and his investors scrambling to rebuild a company as quickly as possible. Along the way, he’s learning how hard it can be to restart a smart home company after it has essentially shut down.

        On April 15, Insteon users noticed that their hubs weren’t working. Their connections to services such as Alexa and Google were broken and their mobile apps could no longer connect to their hubs. A few days later all was explained via a note on the Insteon web site saying that the company has failed to make it as a business. Customers also received an email from a company representing Insteon creditors noting that they would be paid after the sale of the assets by a trustee.

        • Ken ShirriffReverse-engineering a 1960s cordwood flip flop module with X-ray CT scans

          How can you find out what’s inside a sealed electronics module from the 1960s? In this blog post, I reverse-engineer an encapsulated flip flop module that was used for ground-testing of equipment from the Apollo space program. These modules are undocumented1, so their internal circuitry is a mystery. Thanks to Lumafield, I obtained a three-dimensional CT scan of the module that clearly shows the wiring and components: transistors, diodes, resistors, and capacitors. From these images, I could determine the circuitry of this flip flop module.

          The photo below shows the module, a block of plastic 1.5 inches long with 13 pins. I could determine most of its functionality by probing it on a breadboard—conveniently, the pin spacing is compatible with standard solderless breadboards. The module is a flip flop (as the FF label suggests) but some questions remained. Last month, I reverse-engineered a simpler Motorola module (post) using 2-D X-rays. However, this flip flop module was much more complex and I couldn’t reverse-engineer it from standard X-rays.
