  • How to Install and Use Docker on Rocky Linux 8 – VITUX

    Imagine a box in which you can put all of your files, and it will maintain integrity. This is what Docker does, providing an easy way to manage containers for any application on-premise or cloud-hosted with ease.

    What’s even better about this tool: It comes free (yes, really) as well as being open source so that everyone benefits from its use–not just those who have paid subscriptions like most big companies do these days.

    Docker allows you to put your application in a container, ship it and preserve the environment, as well as make sure that all of those pesky updates don’t break it. You can access much smaller servers and reduce bandwidth since everything is self-contained.

    The Docker team has been working very hard on this tool for a while now–and they have succeeded in making a very excellent and useful product. Those who have been working on or with Linux for a time can appreciate how amazing this is–finally an IT tool that works.

  • Guide to Linux Ubuntu/Debian log files for beginners

    Updated – Ubuntu logs system events into the log files in order to help administrators maintain, analyze and diagnose system related issues and applications problems.

    Log files contain messages related to kernel, services and applications events that are kept on a centralized repository of log files under /var/log directory.

    There are various log files in Linux Ubuntu for different informations. For instance, there is a default log file dedicated to the system, another for security messages another for cron tasks. These log files are actually plain text (ASCII) written in a standardized log file format. Many of these log files are generated by the so called system log daemon, syslogd while some other applications generate their proper logs by writing to files under the directory /var/log.

    The log files generated can therefore be classified into four categories: event Logs, application Logs , system Logs and service Logs.

    In this article, we will provide an overview of Ubuntu log files, and show how to configure and use syslogd. You will also learn how log rotation works and how to view and read the log files. A brief introduction to systemd will be provided at the end .

  • Valve answer questions about the Steam Deck in a new FAQ, anti-cheat for all Linux systems | GamingOnLinux

    After gathering questions from pretty much everyone, Valve has put up a new official FAQ page for the Steam Deck that answers some pretty important questions and it's good news.

    One really important questions was answered on anti-cheat support too. There were concerns that with Valve working to get the likes of Easy Anti-Cheat and BattlEye to support Proton that it might somehow be locked to the Steam Deck. Thankfully, that is simply not the case. Valve has said very clearly that the improvements will "will make it to all systems using Proton".

    [...]

    Sounds like it's pretty much all good news. Being able to boot multiple systems clearly shows how it really is just a small-form factor PC, that will come with SteamOS (based on Arch Linux) by default. Users will be able to do whatever they want with it.

  • Q1K3 is a homage to Quake made with 13 kb of JavaScript | GamingOnLinux

    Games seem to be getting bigger all the time taking up vast amounts of drive space but what can be done with very little resources? Quite a lot actually as the Quake homage Q1K3 has shown.

    Developed for the js13kGames competition, where developers are given one month to create a game with HTML5 / JavaScript and possibly get a prize. The main constraint is that the file size limit for submissions is 13 kilobytes. It doesn't sound like a lot and not much bigger than a blank LibreOffice document.

    One clever developer named Dominic Szablewski announced Q1K3 as their entry, which is a first-person Quake inspired shooter and it's actually quite amazing considering just how tiny it is.

5 reasons to switch to Firefox right now

Filed under
Moz/FF

Mozilla Firefox was one of the applications that opened my eyes to open source. It wasn't by any means the tipping point, but it was part of a larger cumulative effect of several open source applications grabbing my attention, which ultimately resulted in me switching to Linux, and never looking back. Since switching to Firefox, which occurred well before I consciously changed to open source, I've been an avid Firefox user. My mobile phone was a Firefox OS mobile phone, and it was until the project was abandoned. Interestingly, though, I didn't necessarily consider myself a Firefox fan. I used it then and continue to use it today because it continues to be the best browser available in many different ways. Here are five reasons you should switch to Firefox right now.

How I Built My New Linux Gaming Desktop in 2021 with AMD (CPU+GPU) and GNU Guix

Filed under
Hardware
Gaming

After my unexpected luck in getting a new GPU (the AMD 6700XT), it was finally time to build a new computer. While my previous desktop was still ticking, at 6 and a half years old (an Intel i5-4690K, Nvidia GTX 970; see details in our gaming rigs article) it was certainly not up to 4K gaming and VR. The GPU was by far the hardest thing to get, but by this summer most everything else was available and at more regular prices.

[...]

Overall, the main components follow a pretty typical mid-range to enthusiast gaming build for 2021. These are all solid, well recommended choices, at a good price to performance ratio. I’ll discuss my choice to move to all AMD below, but overall there wasn’t anything I had to worry about being Linux compatible. These days I’d mostly be concerned about Wi-Fi, along with any specialty hardware. I opted out of Wi-Fi since my desktop is right next to my router for a wired connection, though the Bluetooth would be handy for things like controlling the Valve Index’s base stations. That and Wi-Fi can be handled with a cheap USB adapter if I want it. (Honestly, the motherboard I wanted in white also didn’t have Wi-Fi, so that made the choice easier, too.) The only thing for me was wondering about controlling all that RGB, but open source comes through again, as I’ll detail later.

In terms of specifics the 5600X is a great performer with the latest Zen 3 architecture and good single core performance to go with the 6 cores and 12 threads. This has become easily available, at least in the US, at or below MSRP. There are some great Zen 2 CPUs to pick from, but in my case I wanted the latest (I tend not to upgrade frequently, obviously) as well as plenty of power for photo editing and compiling as I’ve been contributing patches and packages to Guix.

  • The rest of the 5.15 merge window

    Linus Torvalds released 5.15-rc1 and closed the merge window for this release on September 12; at that point, 10,471 non-merge changesets had found their way into the mainline repository. Those changesets contain a lot of significant changes and improvements. Read on for a summary of what came into the mainline in the roughly 7,000 changesets pulled since our first-half summary was written.

  • The folio pull-request pushback

    When we last caught up with the page folio patch set, it appeared to be on track to be pulled into the mainline during the 5.15 merge window. Matthew Wilcox duly sent a pull request in August to make that happen. While it is possible that folios could still end up in 5.15, that has not happened as of this writing and appears increasingly unlikely. What we got instead was a lengthy discussion on the merits of the folio approach.

    The kernel's memory-management subsystem deals with memory in pages, a fundamental unit that is generally set by the hardware (and is usually 4KB in size). These "base" pages are small, though, so the kernel often needs to deal with memory in larger units. To do so, it groups sets of physically contiguous pages together into compound pages, which are made up of a head page (the first base page of many in the compound page) and some number of tail pages. That leads to a situation where kernel code that is passed a struct page pointer often does not know if it is dealing with a head or a tail page without explicitly checking.

    It turns out that the "make sure this is a head page" checks add up to a certain amount of expense in a running kernel. The use of struct page everywhere also makes kernel APIs unclear — it can be difficult to know if a given function can cope with tail pages or not. To address this problem, Wilcox created the concept of a "folio", which is like a struct page but which is known not to be a tail page. By changing internal functions to use folios, Wilcox is able to speed up the kernel and clean up the API at the same time. The patch set is huge and intrusive, but it appeared to have overcome most resistance and be ready to head into the mainline kernel.

  • Extended attributes for special files

    The Linux extended-attribute mechanism allows the attachment of metadata to files within a filesystem. It tends to be little used — at least, in the absence of a security module like SELinux. There is interest in how these attributes work, though, as evidenced by the discussions that have followed the posting of revisions of this patch by Vivek Goyal, which seeks to make a seemingly small change to the rules regarding extended attributes and special files.

    Specifically, extended attributes (often referred to as "xattrs") are name-value pairs that can be attached to a file. The name of an extended attribute is divided into a namespace and an identifier within the namespace. The namespace is currently one of security, system, user, or trusted; each namespace has its own special rules. As a general rule, system and trusted see little use. The security namespace, instead, is used by a number of Linux security modules. An example of a security attribute can be seen by running getfattr on a system that is set up for SELinux

  • Brave is a browser of many contradictions

    It’s not just popup ads that annoy people. You also have creepy companies like Facebook and Google following your every move on the internet. They know what you have been up to and use this information to offer tailored ads. Worse still, sometimes they sell this information to third parties. So we have seen a rise in privacy extensions for browsers too.

    That is the vision upon which Brave browser was born. It’s easily one of the fastest-growing browsers on the [Internet]. They claim to be a privacy-focused browser. It’s easy to see what Brave is all about. Instead of you having to install Chrome, install Adblock, tweak privacy settings and so on you can just install Brave. It is based on Chromium, the engine that powers Chrome, Chromium and Edge.

  • Google Docs in a clean-room browser

    With the news that Google would be phasing in a new version of Google Docs I thought we ought to get the current version working in Flow. Because of many bug fixes in Flow for other websites, Google Docs now seemed to load mostly fine, though it rendered without word wrap and you couldn’t actually type into it.

    Like Google Mail, Google Docs almost entirely consists of obfuscated JavaScript, some of it common between the two. Its HTML structure is quite simple, though it uses hidden iframes for various purposes (one for key input and another for calculating word widths, amongst others). Over the course of the couple of months I identified over 30 distinct issues that needed fixing, and I’ll discuss the more interesting ones in the second section of this blog.

  • Linux: Central real-time patches integrated after 17 years [Ed: Translation from German]

    The heart of real-time support for Linux has finally made it into the official kernel. As before, real-time support cannot be activated there, because there are still some medium-sized and all kinds of small construction sites. Developers of the project, which has been dragged out due to lack of money, discussed these things at the Linux Plumbers Conference 2021, which is currently taking place. There it was also discussed how they want to maintain the whole thing in the future.

    [...]

    The recorded changes to locking techniques such as spinlocks, mutexes and Rwlocks are ultimately the core of it all, with the PREEMPT_RT in autumn 2004 still started under a different name Has. The now integrated adjustments added up to a whopping seventy patches. They allow a kernel compiled with real-time support to interrupt almost all of the tasks it has performed at any time without any major delay in order to temporarily devote itself to more important things.

    This is crucial for real-time support: Linux can quickly turn to programs that always have to complete a certain task in a pre-defined time – even if something unimportant demands a lot from the system and creates adverse conditions. A marking on the process determines which programs the kernel should prefer. For many PCs and servers in particular, this is of no interest, because the greater responsiveness means that other tasks are interrupted more frequently and run more slowly.

  • Do We Still Need a Bastion?

    There is a growing discussion among network engineers, DevOps teams, and security professionals about the security benefits of bastions. Many assume that they are the “old way” of network access and have little relevance in the modern cloud native stack. These speculations are not irrelevant as in recent years, the corporate IT network perimeter as we knew it is diminishing, and the concept has been shifted to data, identity, and compute perimeter. Software-defined networking solutions have overtaken hardware firewall boxes, and the requirement of managing bare metal servers has shifted to container deployed or even serverless applications. Where do bastions fit in these scenarios? Do we even need one?

  • What’s in a package

    There is no shortage of package managers. Each tool makes its own set of tradeoffs regarding speed, ease of use, customizability, and reproducibility. Guix occupies a sweet spot, providing reproducibility by design as pioneered by Nix, package customization à la Spack from the command line, the ability to create container images without hassle, and more.

    Beyond the “feature matrix” of the tools themselves, a topic that is often overlooked is packages—or rather, what’s inside of them. Chances are that a given package may be installed using any of the many tools at your disposal. But are you really getting the same thing regardless of the tool you are using? The answer is “no”, contrary to what one might think. The author realized this very acutely while fearlessly attempting to package the PyTorch machine learning framework for Guix.

Postgres 14: It's The Little Things

Filed under
Server

A lot of years Postgres will have some big pillar or theme to the release. Often this is thought of after the fact. Everything that is committed is looked at and someone thinks, "This is the key thing to talk about." In Postgres 9.2 it was JSON, in 9.4 it was JSONB, in 10 it was logical replication, 12 was a broader performance theme. While I look forward to each of these big highlights, in each release I'm equally excited to browse through and pull out the small things that simply make my life better.

Postgres is, and for some time will continue to be, the first database I turn to. As Postgres focuses on the little things, it just deepens my commitment to it. Why look elsewhere when the bond just grows over time? So today I wanted to call some extra attention to those little things, the ones that don't get the spotlight, but simply make a developer's life better.

[....]

I've talked a lot over the years about how I'm a fan of psql - the CLI client that comes with Postgres. It's quite feature rich, more so than most CLI tools I know. It has the ability to customize it via a psqlrc, a lot of handy shortcuts, ability to format the output of a query with \x and \x auto to auto format it, and features like \watch to auto re-run a query every few seconds.

When I started going through the psql improvements in Postgres 14 it was great to see not just 1 new feature but a slew of them.

First, there's a nice improvement contributed by two of my colleagues to the shortcut \df to allow you to see function and operator arguments. This helps reduce the number of matches for overloaded entries.

    With our 12th episode of the Software Freedom Podcast we dig into the history and the beginning of enforcing Free Software licences, especially the GNU General Public Licence (GNU GPL). Together with Till Jaeger, who has been working alongside Harald Welte for enforcing the GNU GPL in the first court cases in Germany, we talk about the long way we have come since those early days.

    Our guest, Till Jaeger, discusses with our host, Matthias Kirschner, how the decision to go to court and stand up for the rights of copyleft licences came about. Till and Matthias tell an exciting story about those first steps on this new legal ground. They also highlight the short term and long term impacts of the first court decision in favour of Free Software. For example, how more and more information about licensing and especially using a Free Software licence became available and publicly known. But also how workshops, like the FSFE's yearly Legal and Licensing Workshop were created for those interested in using and being compliant to Free Software licences.

    Discover together with us the changes that have come from those first steps to the acceptance of Free Software in companies. Till has been involved with Free Software licensing for a long time and provides a deep and well rounded insight into the history of enforcing the GNU GPL. To give this episode a perfect ending, Matthias and Till also talk about some of the most common misunderstandings of Free Software licensing. This is the perfect episode for everyone to get an insight into one of the most important events in the history of enforcing Free Software licences.

  • Home Automation Terminal With Cyberpunk Style

    The OLKB-Terminal designed by [Jeff Eberl] doesn’t have a battery, can’t fold up (even if it seems like it could), and is only portable in the sense that you can literally pick it up and move it somewhere else. So arguably it’s not really a cyberdeck per se, but it certainly does look the part. If you need to be furiously typing out lines of code in a dimly lit near-future hacker’s den, this should do you nicely.

    [Jeff] has provided everything you’d need to recreate this slick little machine on your own, though he does warn that some of the hardware decisions were based simply on what he had on-hand at the time, and that better or cheaper options may exist. So for example if you don’t want to use the Raspberry Pi 4, you can easily swap it out for some other single-board computer. Though if you want to change something better integrated, like the LCD panel, it will probably require modifications to the 3D printed components.

    The non-exclusive agreement will see Open Robotics extending ROS 2, the latest version of the open-source robotics framework, to better support Nvidia hardware – and in particular its Jetson range, low-power parts which combine Arm cores with the company's own GPU and deep-learning accelerator cores to drive edge and embedded artificial intelligence applications.

    "Our users have been building and simulating robots with Nvidia hardware for years, and we want to make sure that ROS 2 and Ignition work well on those platforms," Brian Gerkey, Open Robotics' chief exec, told The Register.

  • This robotic bartender serves up drinks using a Nano RP2040 Connect and the Arduino Cloud | Arduino Blog

    Mixing up perfect, custom cocktails often requires months or even years of training, in addition to having to know a plethora of recipes. But Jithin Sanal wanted to pour his favorite drinks without spending the extra time and effort, so he concocted a robotic cocktail mixer to perform this task for him. It operates by using a series of ingredient reservoirs, pumps, an Arduino Nano RP2040 Connect, and a few relays to dispense a precise quantity of the desired ingredient into a container. Sanal also designed and fabricated his own circuit board to connect each component together in a circuit.

    Rather than having a bunch of physical buttons on the front of the robotic cocktail mixer, Sanal instead opted to use the Arduino Cloud with five virtual ones that each correspond to a single drink. When a button is pressed, a function is executed on the Nano RP2040 Connect that activates the correct pumps in the specified order for a certain duration. By utilizing this method, users can be confident their drink is perfectly made every single time. More drinks can be added to the system simply by adding another button within the IoT Cloud and creating the associated function in the RP2040’s code.

  • Firmware Find Hints At Subscription Plan for reMarkable Tablet

    To their credit, at least reMarkable is being upfront by admitting a subscription model is being considered. It also sounds like existing users will be grandfathered in when it goes live, which should come as some comfort to current owners. But for prospective buyers, this could literally change everything. It’s bad enough that cloud synchronization of documents would potentially be time-limited, though we’ll admit there’s some justification in that the company is obviously incurring costs by hosting these files. Limiting features based on subscription tier on the other hand is simply a step too far, especially on a device that the user purchased outright.

    We’ve already seen the first tentative steps towards developing a free and open source operating system for the reMarkable tablet, and this news is only going to redouble the efforts of those who wish to liberate this very promising piece of hardware from the overbearing software it ships with. What worries us is how the company is likely to respond to such projects if they’ve found themselves in a situation where recurring charges have become necessary to balance the books. We’ve already seen a motorcycle airbag that will only deploy if the wearer has paid up for the year, so is a tablet that won’t let you install additional applications unless you’ve sprung for the premium membership really that far fetched? Sadly, we all know the answer.

  • PHP maintains an enormous lead in server-side programming languages

    The venerable web programming language PHP is a source of frequent complaints and frustration, but according to a report W3Techs released today, it doesn't seem to be going away any time soon.

    W3Techs' web server survey looks for technologies in use by sites in Alexa's top 10 million list; today's report includes a year-on-year chart beginning with January 2010, running all the way through 2021. The survey only includes top sites not out of elitism, but as one part of its effort to avoid data-skewing returns from domain-parking services and spammers, which would otherwise dominate legitimate websites through sheer volume.

    Within that dataset, the story told is clear. Apart from PHP—which held a 72.5 percent share in 2010 and holds a 78.9 percent share as of today—only one other server-side language ever broke a 10 percent share. That one competitor is ASP.NET, which held an impressive 24.4 percent share in 2010 but was down to 9.3 percent in January and 8.3 percent this month.

    Amongst the small fry, the only truly impressive growth to be seen is in Ruby—which at 5.2 percent this month is still seeing continued uninterrupted growth in W3Techs' survey. This might come as a shock if you're mostly familiar with Ruby on Rails, which itself remains viable but seems to be on the decline in popularity.

  • PHP Holds Impressive Lead Among Server-Side Languages

    This share constitutes an enormous lead over PHP’s rivals, with only one other server-side language ever reaching a 10 percent share. As Jim Salter reports, ASP.NET held a 24 percent share in 2010 but usage has now declined to 8.3 percent.

  • 10 Best Open Source Linux Code Editors [Ed: Very bad list. The first two in the list are Microsoft and even proprietary software with surveillance or 'telemetry' that spies on coders]

    Furthermore, IDEs provide users with plug-ins for adding the extra capability to the program and auto-complete tags and classes to make programming faster. Users can also utilize the pre-provided piece of code in their programs. IDEs make coding faster and easier and hence today we’re here to discuss the 10 best Code Editors (IDEs) available for Linux.

Microsoft Exchange Autodiscover protocol found leaking hundreds of thousands of credentials

Filed under
Microsoft
Security

A flaw in Microsoft's Autodiscover protocol, used to configure Exchange clients like Outlook, can cause user credentials to leak to miscreants in certain circumstances.

The upshot is that your Exchange-connected email client may give away your username and password to a stranger, if the flaw is successfully exploited. In a report scheduled to be published on Wednesday, security firm Guardicore said it has identified a design blunder that leaks web requests to Autodiscover domains that are outside the user's domain but within the same top-level domain (TLD).

Exchange's Autodiscover protocol, specifically the version based on POX XML, provides a way for client applications to obtain the configuration data necessary to communicate with the Exchange server. It gets invoked, for example, when adding a new Exchange account to Outlook. After a user supplies a name, email address, and password, Outlook tries to use Autodiscover to set up the client.

  • Location history: How your location is tracked and how you can limit sharing it

    In real estate, the age old mantra is “location, location, location,” meaning that location drives value. That’s true even when it comes to data collection in the online world, too — your location history is valuable, authentic information. In all likelihood, you’re leaving a breadcrumb trail of location data every day, but there are a few things you can do to clean that up and keep more of your goings-on to yourself.

    [...]

    For some apps, location helps them function better, like navigating with a GPS or following a map. Location history can also be useful for retracing your steps to past places, like finding your way back to that tiny shop in Florence where you picked up beautiful stationery two years ago.

    On the other hand, marketing companies use location data for marketing and advertising purposes. They can also use location to conduct “geomarketing,” which is targeting you with promotions based on where you are. Near a certain restaurant while you’re out doing errands at midday? You might see an ad for it on your phone just as you’re thinking about lunch.

    Location can also be used to grant or deny access to certain content. In some parts of the world, content on the internet is “geo-blocked” or geographically-restricted based on your IP address, which is kind of like a mailing address, associated with your online activity. Geo-blocking can happen due to things like copyright restrictions, limited licensing rights or even government control.

  • Chrome 94 Released for Android, macOS, Windows, Linux: What's New | Technology News

    Chrome 94 stable update has been released by Google for Android, iOS, Mac, and Windows operating systems. The update will be rolled out over the coming weeks and it brings new security features, new functionality, and bug fixes. Google Chrome 94 stable is the first version of Chrome of the new four-week release cycle. Previously, Chrome update was released every six weeks. Its features include HTTPS-First mode that makes users browsing more secure. Also, Google said that 19 different security issues were fixed in the Chrome 94 version.

    The update for Google Chrome was announced through a blog post on September 21. Chrome 94 introduces HTTPS-First mode. It is available in Chrome for desktop systems and for Android. HTTPS is a more secure version of HTTP and many websites support it. With the latest update, the browser will also show a full-page warning when the user loads a site that doesn't support HTTPS. This ensures privacy when using public Wi-Fi. Google says this was previously planned for Chrome 92.

  • Google emits Chrome 94 with 'Idle Detection' API to detect user inactivity amid opposition

  • Google Finally Shifting To "Upstream First" Linux Kernel Approach For Android Features

    Google's Android had been notorious for all of its downstream patches carried by the mobile operating system as well as various vendor/device kernel trees while in recent years more of that code has been upstreamed. Google has also been shifting to the Android Generic Kernel Image (GKI) as the basis for all their product kernels to further reduce the fragmentation. Looking ahead, Google is now talking of an "upstream first" approach for pushing new kernel features.

    Google's Todd Kjos talked today during Linux Plumbers Conference (LPC2021) around their Generic Kernel Image initiative. With Android 12 and their Linux 5.10 based GKI image they have further cut down the fragmentation to the extent that it's "nearly eliminated". With the Android 12 GKI, most of the vendor/OEM kernel features have now either been upstreamed into the Linux kernel, isolated to vendor modules/hooks, or merged into the Android Common Kernel.

  • Clang-format for Xen Coding Style Checking Scheduled - Xen Project

    At the moment there is no tool that would allow to format patches in Xen. The idea of Xen-checker is to use the clang-format approach as a base for Xen ‘checkpatch’ process. The new tool consists of modified .clang-format configuration file to automate Xen patches format checking and reformatting. The tool can be used as a pre-commit hook to check and format every patch automatically. Some features are missing in the clang configurator, so new clang-format options have been proposed for more flexible code formatting. Also, the purpose of the topic is to start the discussion about the existing rules for Xen code formatting to eliminate possible inaccuracies in the work of the Xen checker. This will make it easier to adhere to the unanimous decision.

Linux 5.15-rc3

So after a somewhat rocky merge window and second rc, things are now
actually looking pretty normal for rc3. Knock wood.

There are fixes all over, and the statistics look fairly regular, with
drivers dominating as they should (since they are most of the tree).
And outside of drivers, we have a fairly usual mix of changes -
architecture fixes, networking, filesystems, and tooling (the latter
being mostly kvm selftests).

Shortlog appended, it's not too long and easy to scan through to get a
flavor for the details if you happen to care.

Please do give it a whirl,

Huawei launches OS openEuler, aims to construct 'ecological base of national digital infrastructure'

Chinese tech giant Huawei launched openEuler operating system (OS) on Saturday, another self-developed OS after the HarmonyOS, as it tries to "solve the domestic stranglehold problem of lacking its homegrown OS in basic technology," and build a full-scenario covered ecosystem to prepare for more US bans. The openEuler OS can be widely deployed in various forms of equipment such as servers, cloud computing and edge computing. Its application scenarios cover Information Technology, Communication Technology and Operational Technology to achieve unifying an operating system with multi-device support, according to the company's introduction. In the ICT field, Huawei provides products and solutions such as servers, storage, cloud services, edge computing, base stations, routers, industrial control among others, all of which need to be equipped with an OS. Huawei has therefore been building capabilities to achieve a unified OS architecture, and meet the demands of different application scenarios, the firm said on Saturday. The openEuler program was initially announced back in 2019 as an open source operating system. Today's launch is an updated one. Read more
