• Excuse me, your memory is leaking. GNOME Software running in the background, taking hundreds of MB of RAM.

  So I noticed today that GNOME software is constantly running in the background taking up to 435 MB of RAM.

  It does that (very) occasionally, unpredictably. I can’t figure out why. Usually, it’s only taking 30-60 MB.

  Obviously that’s a bit much for a program that’s only job is sitting there and telling me when updates are available or waiting for me to install a program, and obviously there are leaks, and indeed, all you apparently need to do is run valgrind on it and it will find some.

• Tender to implement C++ accessibility tests (#202110-01)

  The Document Foundation (TDF) is the charitable entity behind the world’s leading free/libre open source (FLOSS) office suite LibreOffice.

  We are looking for an individual or company to implement C++ accessibility tests.

  The work has to be developed on LibreOffice master, so that it will be released in the next major version.

  The current accessibility tests are rather incomplete and hard to maintain. Additionally, they are written in Java.

A list of the new features is available in the documentation.

• abs function in C

  Why is it necessary for programmers to use the abs() function? It’s accessible in almost every programming language; But how much good is a function that just turns negative values into positive ones? You may find yourself wanting positive numbers occasionally, and the abs() function ensures that you will get them. The abs function is an abbreviation for “Absolute Value” inside the C programming language, and it specifies the distance of a number just on a number line beginning from 0 without taking the direction into account. The abs value of a number, or its absolute value, has always been positive, implying that a distance could never be negative.
  The abs () method returns the absolute appropriate value integers and is specified in the stdlib.h header file. To return the absolute value of a particular number, we must include the stdlib.h header file in our C application. Only positive values are returned by the abs() function.

  Consider the following scenario: If we have an integer number -2 and wish to find the absolute value, we may use the abs() method to have the positive number 2. In addition, when we have an integer number 2 and want to determine the absolute value, we can use the abs() method to return the very same value as 2. It gives the very same number if we provide it with any positive number.

• Printf-style debugging using GDB, Part 2

• Intel Contributes AVX-512 Optimizations To Numpy, Yields Massive Speedups - Phoronix

  Intel has contributed AVX-512 optimizations to upstream Numpy. For those using Numpy as this leading Python library for numerical computing, newer Intel CPUs with AVX-512 capabilities can enjoy major speed-ups in the range of 14~32x faster.

  This summer Intel volleyed their initial AVX-512 code for Numpy and finally this week the code was merged upstream. This open-source AVX-512 code originates from the Intel Short Vector Math Library (SVML) that they open-sourced the code from. Intel has also been working on allowing Numpy to be built against SVML as a separate improvement.

• TSV to CSV on the CLI (if you really have to)

  Regular visitors to this blog will know that I don't like the CSV format. It's awful. In my humble opinion, data workers should aim to use invisible tabs (TSV) or visible pipes (PSV) as field separators in delimited text tables. Sometimes, though, data workers are required to convert a perfectly good TSV or PSV to a CSV. What to do?

  I don't recommend opening the TSV or PSV in spreadsheet software and saving the result as a CSV, unless there are no leading or trailing quotes in the data items, or umatched quotes generally. The original quotes might well disappear in the saved CSV.

  There are a number of TSV-to-CSV programs for the command line. One is in Haskell, for example, and there also routines to do the job in Perl and Python. But if the individual fields in the TSV don't contain commas or quotes, the TSV-to-CSV conversion is simple — use tr:

• Useful Bash Commands You May Not Know About

  Bash is a fairly powerful language to program in, and is also quite easy to start off with.

  After all, it's almost universally the shell you're going to see when you open up your terminal. That makes it extremely useful to get accustomed to.

  There's some powerful commands in Bash that you may not be aware of though, even if you're fairly seasoned with using the language. All of these commands can serve quite useful purposes though, and can make the shell scripts you write cleaner, more maintainable, and just outright more powerful than they could've been before.

• 10 Most Commonly Used FOSS Packages

  The Core Infrastructure Initiative Census Program II report released earlier this year identified the most commonly used FOSS components in production applications, with the goal of understanding potential vulnerabilities in these components and better securing the open source software supply chain.

• Don’t penalise cybersecurity researchers!

  We wrote to the Indian Computer Emergency Response Team regarding a provision in their new Responsible Vulnerability Disclosure and Coordination Policy that penalises cybersecurity researchers for vulnerability disclosures. In our representation, we highlighted how such provisions would create an atmosphere in which researchers would be reluctant about reporting vulnerabilities and recommended that a robust disclosure mechanism be implemented that protects researchers from harm.

  [...]

  Such provisions contribute to a disclosure regime in which security researchers would be liable under the Information Technology Act, 2000 (‘IT Act’), and are penalised for disclosures of genuine security vulnerabilities. Section 43 of the Information Technology Act, 2000 penalizes anyone who gains unauthorized access to a computer resource without permission of the owner, and so fails to draw a distinction between malicious hackers and ethical security researchers. Thus, even when researchers have acted in good faith they may be charged under the IT Act. As we have mentioned earlier, companies have exploited this loophole in the said provision to press charges against cybersecurity researchers who expose data breaches in their companies. The Personal Data Protection Bill, 2019, currently being considered by a Joint Parliamentary Committee, also fails to protect security researchers and whistleblowers. All of this leads to situations in which researchers are reluctant to report vulnerabilities for fear of being sued.

  Clause 7 of the Policy is also in conflict with the Information Technology (The Indian Computer Emergency Response Team and Manner of Performing Functions and Duties) Rules, 2013 (‘2013 IT Rules’) which adapts a cooperative and collaborative approach. Rule 10 requires CERT-IN to interact with stakeholders including research organisations and security experts for preventing cyber security incidents. Under Rule 11(2), CERT-IN is obligated to collaborate with, among others, organisations and individuals engaged in preventing and protecting against cyber security attacks. Thus, by imposing complete and sole responsibility on cyber security researchers for actions undertaken during the discovery of a vulnerability, the policy is in conflict with the collaborative spirit of the 2013 IT Rules and so is a genuine impediment to effective collaboration.

• Airline Passenger Mistakes Vintage Camera for a Bomb

  Back in 2007, I called this the “war on the unexpected.” It’s why “see something, say something” doesn’t work. If you put amateurs in the front lines of security, don’t be surprised when you get amateur security. I have lots of examples.

• How to create an effective security policy: 6 tips

  Are your security policies boring? OK, that’s not entirely fair. Security policies are boring, especially to people outside of IT – in the way that children find their parents’ or teachers’ rules “boring.” There’s a limit to how interesting one can make “best practices for creating strong passwords” sound to the masses.

  The point of such policies is to educate people on organizational rules and the habits of good security hygiene. This is the administrative layer of security controls: all of the rules, standards, guidelines, and training an organization puts in place as part of its overall security program. It’s the human-focused component that rounds out the other two general categories of security controls, according to Terumi Laskowsky, an IT security consultant and cybersecurity instructor at DevelopIntelligence. The other two categories are technical/logical controls (your hardware and software tools) and physical controls (things like building or site access).

  Laskowsky notes that people tend to question the value of administrative controls. That’s partly because it can be difficult to measure or “see” their effectiveness, especially relative to technical or physical controls. But Laskowsky and other security experts generally agree that they are necessary. Security is not a steady-state affair – while our security tooling and processes are becoming more automated, a strong posture still requires human awareness, intelligence, and adaptability.

  “Raising our security awareness through administrative controls allows us to start seeing the patterns of unsafe behavior,” Laskowsky says. “We can then generalize and respond to new threats faster than security companies can come up with software to handle them.”

• Kube by Example expands training curriculum with new learning paths for Kubernetes developers

  We see Kubernetes as the foundation for hybrid cloud, and hybrid cloud as the future of IT. The technology remains among both the most loved and most wanted tools in this year’s Stack Overflow Developer survey. Given its prevalence and strategic importance, we have also seen developers seeking out and engaging with Kubernetes-focused training resources like Kube by Example, an online destination for free Kubernetes-focused tutorials, news and community interaction.

• Celebrating Ada Lovelace with 4 career lessons from women in technology

  Ada Lovelace is known as the first computer programmer. Mainly known for her work with Charles Babbage’s Analytical Engine in the 1800s, she was the first to recognize that the machine could do more than simple calculation — that it could follow a set of instructions (a program) to perform tasks. While Babbage’s computer was never built, Lovelace is credited with writing up an algorithm to be carried out by such a machine. Now, every year in mid-October, we celebrate women tech pioneers on Ada Lovelace Day.

• Igor Seletskiy Steps Down to Assure AlmaLinux Independence - FOSS Force

  Today Igor Seletskiy, co-founder and CEO of CloudLinux, announced that he’s stepped down from his role as chairman of the board at the AlmaLinux Foundation, and is also vacating his seat on the board of directors.

  The foundation, which he started earlier this year, produces AlmaLinux, a drop-in replacement for Red Hat’s CentOS Linux that Seletskiy announced in December, shortly after Red Hat said it was moving the Linux distribution from its traditional role as a downstream clone of Red Hat Enterprise Linux to sit upstream as RHEL’s “nightly build.”

  A replacement was needed because many organizations, including many Fortune 500 enterprises, use CentOS in production as a way to take advantage of RHEL’s stability without having to pay for support contracts.

  Both Seletskiy and the AlmaLinux Foundation are very clear there’s no palace intrigue behind this move. The new distro’s founder is stepping down not because of some power struggle within the organization, but because he wants the distro he birthed to have a life of its own as an independent project.

• Digital transformation: 3 myths the pandemic busted

  When the pandemic struck, most organizations had no choice but to accelerate their digital technology adoption. Many condensed into a matter of months what might otherwise have been years of consideration, strategizing, and change.

  According to a survey by McKinsey, the pandemic sparked a seven-year increase in the rate at which companies developed digital or digitally enhanced offerings. It accelerated the digitization of their customer and supply-chain interactions and internal operations by three to four years.

  This shift sparked a new reality for today’s organizations to remain competitive and meet customers’ changing needs. But while enterprises have certainly dedicated more resources to the process of digital transformation, many misconceptions still remain.

  This month Jens Axboe has been making some remarkable improvements to the Linux block code for squeezing out every bit of I/O potential of the system. Yesterday Jens Axboe was hitting 7.2M IOPS with new persistent DMA map patches that also shaved off around 10% of synchronization latency.

• Loongson Volleys Latest Patches For LoongArch Linux Support - Phoronix

  Chinese vendor Loongson continues working on their Linux kernel patches enabling the LoongArch processor ISA as their fork from MIPS. While early on when copying existing MIPS open-source code they were quick to call their new ISA "not MIPS", in these later patch series they continue to refer to their ISA as "a bit like MIPS or RISC-V."

  LoongArch debuted this summer with their Loongson 3A5000 processors and since then their engineers have been working to get the LoongArch support into the mainline kernel. Loongson though has ruffled some feathers of the upstream kernel developers with in some areas just copying existing MIPS code.

• Mesa 21.3 Fixes Issue Of Some Games Having Transparency Issues Under Wayland - Phoronix

  Landing in time for the imminent Mesa 21.3 feature freeze / code branching is support for the EGL_EXT_present_opaque extension on Wayland. While this EGL extension may not sound too exciting, for some OpenGL games on Wayland it will address some transparency issues.

  The issue stems from this issue ticket opened during the summer by game porter Ethan Lee. The issue is around needing an EGL equivalent to VkCompositeAlphaFlagBitsKHR as "we've got a whole lot of games that are unintentionally translucent in Wayland." Portal 2 is among the games as a result having issues under native Wayland.

• Vulkan 1.2.196 Introduces H.265 Encode Extension - Phoronix

  Arriving back in April were the initial Vulkan Video extensions that included support for video decode of H.264 and H.265 while the initial video encode support was limited to H.264. Out today with Vulkan 1.2.196 is the new extension allowing for H.265 encoding with this new industry-standard video API.

  Vulkan 1.2.196 introduces the provisional VK_EXT_video_encode_h265 extension. This extension was worked on by AMD, Intel, and NVIDIA but at least under Linux only the NVIDIA proprietary driver currently exposes Vulkan Video encode/decode support. Presumably this morning NVIDIA will be issuing a new Vulkan beta driver providing timely support for this new H.265 encode provisional extension.

Today AMD is officially launching the Radeon RX 6600 graphics card as a trimmed down model from the Radeon RX 6600 XT that launched back in August. This new (non-XT) model has a suggested price of $329 USD and here is a look at how well this RDNA2 graphics card is performing under Linux.

The AMD Radeon RX 6600 graphics card features 28 compute units, 1792 stream processors, a 2044MHz game clock with up to 2491MHz boost clock, 8GB of GDDR6 video memory, and 32MB infinity cache.

• Install Docker and Portainer - blackMORE Ops

  Docker is a set of platform as a service (PaaS) products that use OS-level virtualization to deliver software in packages called containers. Containers are isolated from one another and bundle their own software, libraries and configuration files; they can communicate with each other through well-defined channels. Because all of the containers share the services of a single operating system kernel, they use fewer resources than virtual machines. The service has both free and premium tiers. The software that hosts the containers is called Docker Engine.

  Portainer CE is a lightweight ‘universal’ management GUI that can be used to easily manage Docker, Swarm, Kubernetes and ACI environments. It is designed to be as simple to deploy as it is to use. Portainer consists of a single container that can run on any cluster. It can be deployed as a Linux container or a Windows native container. Portainer allows you to manage all your orchestrator resources (containers, images, volumes, networks and more) through a super-simple graphical interface. A fully supported version of Portainer is available for business use.

  Open-source software is released under a specific license that gives users the right to download, use, or change the software and its source code. Unlike commercial software, which typically has a protected source code and proprietary file formats, open-source software projects are not profit-driven and encourage users to modify and share their code with the wider community. Often the goal of these projects is to develop applications that can accommodate multiple viewpoints and ways of working. Some well-known open-source projects include the Linux operating system, the WordPress web publishing platform, and the audio-editing application Audacity.

• Apple II Programming: From A Cabin In The Woods

  Adam: Hello, and welcome to CoRecursive. I’m Adam Gordon Bell. Each episode, a guest shares the story behind a piece of software being built. Today’s episode is about remote work. Well, sort of. I’ve been working from my home office for almost exactly 10 years now. And when everyone started working from home, I felt like I had some tips to share, like to break up the Zoom meetings you can just go for walking meetings. Just call in on your phone. It makes a big difference. But I’m not totally sure we figured out all that remote work can be. So I found someone who has something to teach me about remote work. I think that he might be the original remote software developer. He left California behind for a lower cost of living in Oregon. And from Oregon, he developed software for Apple. But the kind of surprising thing is he did this all in 1976. And he did it so well he became rich and even briefly quite famous.

  Paul: That’s 60s artist, whose name escapes me, said everybody is famous for 15 seconds. I was famous for slightly longer than that. But during that time, it was nuts. People would show up and try to ask for autographs and stuff. It was weird. I mean, it never occurred to me that people would want the autographs of a computer programmer. I mean, that’s just not like the normal, famous person kind of an image I have in my mind.

  Adam: That was Paul Lutus. He built Apple Writer for the Apple II. And he thinks there’s something that we, as a profession, are missing, something that we’ve forgotten. But to understand his story and how he got on the front page of the Wall Street Journal, how he got interviewed for national TV programs and all for writing software, we need a little background.

  A pocket-sized TV is not a big deal today. But in 1983, cramming a CRT into your pocket was quite a feat. Clive Sinclair’s TV80 or FTV1 did it with a very unique CRT and [Dubious Engineering] has a teardown video to show us how it was done.

  A conventional CRT has an electron gun behind the screen which is why monitors that use them are typically pretty thick. The TV80’s tube has the electron gun to the side to save space. It also uses a fresnel lens to enlarge the tiny image.

• Bendable Colour EPaper Display Has Touch Input Too | Hackaday

  The Interactive Media Lab at Dresden Technical University has been busy working on ideas for user interfaces with wearable electronics, and presents a nice project, that any of us could reproduce, to create your very own wearable colour epaper display device. They even figured out a tidy way to add touch input as well. By sticking three linear resistive touch strips, which are effectively touch potentiometers, to a backing sheet and placing the latter directly behind the Plastic Logic Legio 2.1″ flexible electrophoretic display (EPD), a rudimentary touch interface was created. It does look like it needs a fair bit of force to be applied to the display, to be detectable at the touch strips, but it should be able to take it.
