• C Programming Examples on Linux for Beginners

  C programming language is one of the good choices for learning computer programming for the beginners. The basic programming logic can be learned easily by using C language as a first language. Java is considered as first programming language by some people, but I think, it is better to learn structured or procedural programming using C language before learning any object-oriented programming. The basic C programming on Linux is shown in this article by using different examples for the beginners.

• Monitorix 3.12.0 released

  Another great Perl software that I find very useful is Monitorix.

  Monitorix is FOSS lightweight system monitoring designed to monitor as many services and system resources as possible.

  The tl;dr is that it works really well for monitoring stand alone machines- which is what I used it for. It's tracks all sorts of metrics with minimal configuration by me, and with packages for most distros its trivial to install and update.

• Book review - Machine Learning with Python for Everyone, By Mark E. Fenner

  Machine learning, one of the hottest tech topics of today, is being used more and more. Sometimes as the best tool for the job, other times perhaps as a buzzword that is mainly used as a way to make a product look cooler. However, without knowing what ML is and how it works behind the scenes, it’s very easy to get lost. But this book does a great job in guiding you all the way up from very simple math concepts to some sophisticated machine learning techniques.

• Python 3.8.2 and 3.9.0a4 are now available

  On behalf of the entire Python development community, and the currently serving Python release team in particular, I’m pleased to announce the release of two of the latest Python editions.

  Python 3.8.2

  Python 3.8.2 is the second maintenance release of Python 3.8 and contains two months worth of bug fixes. Detailed information about all changes made in 3.8.2 can be found in its change log. Note that compared to 3.8.1, version 3.8.2 also contains the changes introduced in 3.8.2rc1 and 3.8.2rc2.

• Build Systems with Speed and Confidence by Closing the Loop First!

  A completely finished “loop” is when you can provide the required input to your system, and it produces the desired output (or side effects, if that’s how you like it). The “Close the loop first” technique is about closing this loop as fast as possible by creating a barebones version of it first, providing all or some required inputs, and generating a partial form of the desired output.

  Once we have closed this barebones loop, we can then begin implementing behaviours from the inside out, so that with each new change our loop starts looking more like the actual system we want.

  Sure, this is nothing new, right? We have all heard of this advice in various forms: build a proof of concept as quickly as possible; validate the unknowns first; if you want to deliver a car, deploy a skateboard first, etc. This is similar, but I am talking today purely from a “programming” point of view. In addition to helping you fail fast, “closing the loop” first also lets you build systems with more speed.

• The Facebook Container for Firefox

  Even with the ongoing #deletefacebook movement, not everyone is willing to completely walk away from the connections they’ve made on the social platform. After all, Facebook — and its subsidiary Instagram — is where the mountain biking club organizes rides, people post pet pics, dance moves catch on and life’s moments get shared with friends and family, near and far. Since the Cambridge Analytica scandal broke, Facebook has been greeted with more skepticism as it’s been under a hot spotlight on how it gathers, uses and gives access to our personal data for targeted advertising and manipulation, both on and off Facebook platforms. With recent news about their policy not to block false political ads, this targeting gets ever malicious.

• Jira, Bugzilla, and Tales of Issue Trackers Past

  It seems as though Mozilla is never not in a period of transition. The distributed nature of the organization and community means that teams and offices and any informal or formal group is its own tiny experimental plot tended by gardeners with radically different tastes.

  And if there’s one thing that unites gardeners and tech workers is that both have Feelings about their tools.

  Tools are personal things: they’re the only thing that allows us to express ourselves in our craft. I can’t code without an editor. I can’t prune without shears. They’re the part of our work that we actually touch. The code lives Out There, the garden is Outside… but the tools are in our hands.

  But tools can also be group things. A shed is a tool for everyone’s tools. A workshop is a tool that others share. An Issue Tracker is a tool that helps us all coordinate work.

  And group things require cooperation, agreement, and compromise.

  While I was on the Browser team at BlackBerry I used a variety of different Issue Trackers. We started with an outdated version of FogBugz, then we had a Bugzilla fork for the WebKit porting work and MKS Integrity for everything else across the entire company, and then we all standardized on Jira.

• Securing Firefox with WebAssembly

  Protecting the security and privacy of individuals is a central tenet of Mozilla’s mission, and so we constantly endeavor to make our users safer online. With a complex and highly-optimized system like Firefox, memory safety is one of the biggest security challenges. Firefox is mostly written in C and C++. These languages are notoriously difficult to use safely, since any mistake can lead to complete compromise of the program. We work hard to find and eliminate memory hazards, but we’re also evolving the Firefox codebase to address these attack vectors at a deeper level. Thus far, we’ve focused primarily on two techniques...

  [...]

  So today, we’re adding a third approach to our arsenal. RLBox, a new sandboxing technology developed by researchers at the University of California, San Diego, the University of Texas, Austin, and Stanford University, allows us to quickly and efficiently convert existing Firefox components to run inside a WebAssembly sandbox. Thanks to the tireless efforts of Shravan Narayan, Deian Stefan, Tal Garfinkel, and Hovav Shacham, we’ve successfully integrated this technology into our codebase and used it to sandbox Graphite.

  This isolation will ship to Linux users in Firefox 74 and to Mac users in Firefox 75, with Windows support following soon after. You can read more about this work in the press releases from UCSD and UT Austin along with the joint research paper. Read on for a technical overview of how we integrated it into Firefox.

• Nicholas Nethercote: Ad Hoc Profiling

  I have used a variety of profiling tools over the years, including several I wrote myself.

  But there is one profiling tool I have used more than any other. It is capable of providing invaluable, domain-specific profiling data of a kind not obtainable by any general-purpose profiler.

  It’s a simple text processor implemented in a few dozen lines of code. I use it in combination with logging print statements in the programs I am profiling. No joke.

The Cosmo Communicator was released as a crowdfunded handheld device mixing smartphone and a small laptop features such as keyboard and display. It was launched in late 2019 and ran Google Android.

The original units were shipped and fulfilled the requirements of the crowdfunding campaign, but still were missing something the company had wanted to provide: support for Linux.

This is now fixed as Planet Computers, the company that makes Cosmo Communicator, just released a version of Debian Linux, that can be installed on the system, with the tools that the company has provided for free on its website.

In this guide you’ll find a full list of Linux syscalls along with their definition, parameters, and commonly used flags.

You can combine multiple flags by using a logical AND and passing the result to the argument in question.

Linux veterans understand that the keyboard is mightier than the mouse because there are many actions that take multiple mouse clicks but can be accomplished with a single keyboard shortcut. Learning at least a handful of keyboard shortcuts can make you significantly more productive as a Linux user and earn you serious bragging rights in the Linux community.

Like the C3000, the P5900 supports up to 128GB DDR4, now at up to 2933 MT/s. It similarly supports 16x PCIe 3.0, 16x SATA 3.0, 4x USB 3.0, and 4x USB 2.0 interfaces. However, the SATA links can now be reconfigured as up to 16x PCIe 2.0 or 16x USB 3.0, so you can now have up to 32x PCIe lanes. Other features include GPIO, 3x UARTs, and -40 to 85°C support.

We saw no mention of OS support, but we imagine that like the Atom C3000, the Atom P5900 is primarily designed to run Linux. The C3000 has appeared on a variety of Linux-powered networking appliances such as Advantech’s FWA-1012VC, as well as numerous COM Express Type 7 modules like Avnet/MSC’s MSC C7B-DV.

  Sometimes you have may have a large video file, and you want to split that video into many smaller videos with start and end times that you specify yourself. And of course, you don’t want to do it manually with a video editor because it’s gonna take forever.

  What we are talking about for example, is when you have a video of 10 minutes, and you want to create 3 smaller clips out of it such that the first one is between 1:20 and 2:20 for example, and the second one is between 3:00 and 4:00 and the last one is between 7:10 and 8:15. Such things is theoretically hard, but not with Python and its amazing tools!

• One Of Clear Linux's Kernel Patches To Help With Boot Time Proposed For Upstreaming

  Besides Clear Linux delivering often leading x86_64 Linux performance at run-time, when it comes to boot performance it has also been at the forefront -- in some configurations, can boot in 300 ms. Intel has invested significantly in ensuring Clear Linux boots as fast as possible for when running in the cloud or on containers in order to respond to increased demand as quickly as possible as well as for use-cases like Clear Linux within automobiles where they need to get automobile cameras active within two seconds of power on. One of their many kernel patches could be on its way to the mainline kernel.

• Running The Linux 5.6 Kernel With AMD Radeon Graphics

  Now hitting about mid-way through the Linux 5.6 kernel with early fallout having been addressed, we've been ramping up our testing/benchmarking of this next major kernel release. Here is our initial experience with the AMDGPU driver on Linux 5.6.

  Linux 5.6 brings many new features As it concerns the AMDGPU kernel driver, there is reset support for Renoir and Navi, initial bring-up for AMD Pollock, HDCP 2.x support, the kernel bits for Vulkan timeline semaphore support, DP MST DSC compression, and other fixes and code improvements.

• VC4 DRM Driver Gets Patched For BCM2711 / Raspberry Pi 4 Support

Among the changes with HEVC REXT are supporting 4:2:2 and 4:4:4 chroma sampling formats. HEVC Range Extensions are laid out in much more detail in this IEEE.org paper.

• Intel Boosts Gen7 GPU Vulkan Compute Performance By ~330% For Geekbench

  Intel's open-source "ANV" Vulkan driver for Linux doesn't see much attention for pre-Broadwell hardware but today it saw a big improvement for Vulkan compute on aging Gen7 Ivybridge/Haswell era hardware.

  Jason Ekstrand, the lead developer of the Intel ANV Vulkan driver, discovered that in their driver's pipeline code the data cache functionality would end up being disabled when a shader was pulled out of the pipeline cache. For Broadwell/Gen8+ the data cache bit was being ignored but this oversight ended up having huge implications for Gen7 Intel graphics hardware (Ivybridge/Haswell) as the oldest supported by Intel's Vulkan driver.

• Intel Has Accumulated 400+ Graphics Driver Patches So Far For Linux 5.7

  Intel just sent out their initial pull request of new feature changes/improvements to DRM-Next that in turn is for landing in about one month's time when the Linux 5.7 merge window kicks off. With taking longer than usual to send in their first round of feature updates, this first of several pull requests already amounts to over 400 patches.

  While it is a big pull request given the extra time for patches to accumulate, there aren't too many user-facing changes. Though there is a lot of enablement work for Tiger Lake as well as continuing Gen11 Ice Lake and Elkhart Lake work. For Ice Lake / Elkhart Lake there are a number of driver workarounds added. For Gen12 / Tiger Lake there are workarounds, display fixes, RPS is re-enabled, and other work.

• Open source XR runtime (VR/AR) 'Monado' sees a first release

  With the Khronos Group launching the OpenXR specification last year, their aim was to unify Augmented Reality (AR) and Virtual Reality (VR) development while Collabora worked on their open source implementation of Monado.

  Collabora have been hard at work on Monado, a currently Linux-focused open source XR runtime that will eventually also support other platforms. Today, they tagged the very first release. With this release they've worked in new drivers, there's now a set of scripts ready for people to try Monado rather than needing to setup a full development environment, udev rules sorted for USB permissions for XR hardware, distribution packaging and more.

  You can see the release announcement on the Collabora blog, where they note they also have some internships going. As for the code, it's all up on GitLab if you're interested in checking out in this early form. The future of XR on Linux sounds quite exciting, especially with efforts like this and Collabora do some great open source work.

• Monado OpenXR runtime developer update

  We are very happy to tag version 0.1 of the Monado OpenXR runtime for Linux!

  Ever since announcing the project at GDC 2019, we have been working on improving the full open source XR stack to a usable state. Do keep in mind, this is a first tag, not a final release so it will contain some tinkering and is not feature complete! To echo the common phrase 'Be warned, here be dragons!'.

• Excellent Free Tutorials to Learn Prolog

  Prolog is a general purpose, declarative, logic programming language, often associated with artificial intelligence, computational linguistics, intelligent database retrieval, and problem solving. It’s widely used in research and education for natural language processing.

  Automatic backtracking is one of the most characteristic features of Prolog. It’s a form of searching, fundamental to all artificial intelligence techniques. Prolog also supports multi-directional reasoning; arguments to a procedure can freely be designated inputs and outputs in different ways in different procedure calls. This is a powerful theorem-proving technique. Another key feature of Prolog is that its syntax and semantics are closer to formal logic than say Lisp.

  Prolog is generally regarded as a difficult language to get to grips with. But learning the fundamentals of Prolog is definitely worthwhile.

  OpenSMTPD has been found vulnerable to yet another critical vulnerability that could allow remote attackers to take complete control over email servers running BSD or Linux operating systems.
  OpenSMTPD, also known as OpenBSD SMTP Server, is an open-source implementation of the Simple Mail Transfer Protocol (SMTP) to deliver messages on a local machine or to relay them to other SMTP servers.
  It was initially developed as part of the OpenBSD project but now comes pre-installed on many UNIX-based systems.

• Y2K bug has a 2020 echo

  The New Scientist reports on problems with software caused by an echo of the Y2K bug that had every excited in the late 1990s.

  It turns out one of the fixes then was to kick various software cans down the road to 2020. In theory that gave people 20 years to find long term answers to the problems. In some cases they might have expected software refreshes to have solved the issue.

  [...]

  This happens because Unix time started on January 1 1970. Time since then is stored as a 32-bit integer. On January 19 2038, that integer will overflow.

  Most modern applications and operating systems have been patched to fix this although there are some compatibility problems. The real issue comes with embedded hardware, think of things like medical devices, which will need replacing some time in the next 18 years.
