=> ↺ Finding suspicious syscalls with the seccomp notifier | Kubernetes

• Debugging software in production is one of the biggest challenges we have to face in our containerized environments. Being able to understand the impact of the available security options, especially when it comes to configuring our deployments, is one of the key aspects to make the default security in Kubernetes stronger. We have all those logging, tracing and metrics data already at hand, but how do we assemble the information they provide into something human readable and actionable?

• Seccomp is one of the standard mechanisms to protect a Linux based Kubernetes application from malicious actions by interfering with its system calls. This allows us to restrict the application to a defined set of actionable items, like modifying files or responding to HTTP requests. Linking the knowledge of which set of syscalls is required to, for example, modify a local file, to the actual source code is in the same way non-trivial.

=> ↺ How to Visualize Ping Responses on Linux With gping

• If you don’t fancy the text-based output of the ping command, consider installing gping, a CLI utility that visualizes ping responses on Linux.

• ping is a simple yet essential tool for diagnosing network issues on Linux. It can help you check your network connection, see if a remote machine is online, and play a vital part in analyzing connectivity issues, such as dropped packages or high latency.

• But as important as the ping command is, it’s not the most interesting to look at, and interpreting its output in a useful way can be difficult. gping is a graphical command-line utility with additional features which make it easy to visualize ping responses from multiple targets.

=> ↺ 10 Useful tar Commands in Linux With Examples | LinuxCloudVPS Blog

• This blog post will show you the ten most used tar commands in Linux with examples.

• The tar command in Linux provides archiving functionality for compressing or decompressing archive files and modifying and maintaining them. With the tar command, we can create tar, gz, bz2 and gzip archives. Administrators use these commands when they want to save some disk space on the servers or when they are migrating files over two host machines.

• In this tutorial, we are going to execute the tar commands on Ubuntu 22.04 OS, but you can choose any Linux distro. Let’s get started!

=> ↺ Creating a modifiable gzipped disk image | Richard WM Jones

• Dusty Mabe set me a challenge yesterday. He wants to create several compressed disk images that have slightly different content, but are otherwise mostly the same. The disk images are large and compressing them takes a long time (30 minutes each, apparently), so ideally what we’d want to do is compress the disk image just the once and then do the updates on the gzipped image.

• Modifying a file which has already been compressed is not usually possible.

• However if we make some relatively uncontroversial assumptions and accept a few limitations then we can create a compressed disk image which is modifiable in this way, certainly for gzip and xz (I need to investigate zstd).

=> ↺ Improve Website Performance Using gzip and Nginx on Ubuntu 22.04 | LinuxHostSupport

• A website’s performance depends on many factors, and choosing a suitable web server is one of them. You can choose from many web servers, like Apache, LiteSpeed, Nginx, etc.

• Nginx is an open-source web server, it was initially developed by Igor Sysoev and released in October 2004. In Nginx, gzip compression can significantly reduce the size of transmitted data to website visitors.

• Modern web browsers support GZIP compression by default. However, we need to configure our server to serve the compressed resources to our website visitors properly. Without a proper configuration, it could make your server load higher and even slower. This article will show you how to improve website performance using GZIP and Nginx on Ubuntu 22.04.

Games

=> ↺ Godot Engine – Dev snapshot: Godot 4.0 beta 7

• Godot 4.0 has been in beta for over two months, and the overall feature completeness, stability and usability have improved a lot during that time.

• We’ve had beta snapshots every other week, and now we’ve decided to accelerate the cadence to release a new snapshot every week, to get even faster feedback on our bugfixes, and the potential regressions they may introduce.

=> ↺ Latest Steam Client Update Improves New Big Picture Mode, Fixes Borderlands 2 Crash

• The new Steam Client update is here only two weeks after the previous update that introduced the new Big Picture mode that resembles the Steam Deck UI. This update further improves the new Big Picture mode by adding confirmation dialogs for the power menu when shutting down or restarting your PC and fixing several bugs.

• These bug fixes improve displaying of the new Big Picture Mode window with GPU accelerated rendering disabled, improve the on-screen keyboard to show when it’s requested by a game or Proton, improve the “show password” toggle to show or hide the password, and improve the new Big Picture Mode overlay when switching Virtual Menus with an action set, layer, or modeshift.

K Desktop Environment/KDE SC/Qt

=> ↺ KDE e.V. board sprint, Berlin | [bobulate]

• In two weeks, the board of KDE e.V. – and take note that photo of me is before 3 years of COVID-hair – will convene in Berlin for one of our board sprints.

• The board meets weekly online, using the Big Blue Button infrastructure that KDE has for meetings, online get-togethers, virtual sprints and hybrid conferences. In an hour or two we get through the week’s “needs doing now” and “approve this request from the membership or community” items. But some things are not very well suited for online discussion. Sometimes we need to physically sign papers (Germany, old-fashioned, etc.). And of course, drinking tea together is what really makes a team.

Distributions and Operating Systems

=> ↺ Updates for November, 2022 ⋅ elementary Blog

• Folks running OS 6.1 rejoice, because a new version of Files is here with a long-asked-for new feature! You can now choose to have a single-click select folders instead of open them, Windows style. Secondary-click anywhere in a folder view and select “Select Folders with Single Click” to switch to the new file selection mode. We now also only show the overlay bar with more info when a selection is made, so no more fiddly hover behavior. There are also fixes for several reported possible crashes, so make sure to grab this update!

New Releases

=> ↺ NixOS 22.11 “Raccoon” Released with Security in Mind

• One of the most software-rich Linux distributions, NixOS, has released v22.11 with a strong focus on security and updated software versions.

• Many of you are probably thinking, “Yet another new version of one of the many Linux distros.” However, the story is different because we are dealing with a one-of-a-kind beast.

• So, before we go into the dry and dull “statistics” of Linux kernel versions, desktop environments, and software in this NixOS release, we’d like to explain why this Linux distro is exceptional and deserves your attention.

• NixOS is a unique Linux distro due to the concept upon which it is built. However, to avoid further confusion, two key terms should be first defined: Nix, which is a cross-distro package system, and NixOS, which is the Linux distribution itself.

=> ↺ IPFire 2.27 – Core Update 172 is available for testing

• Despite being currently busy with an IPFire 3 hackathon, we found the time to release the next Core Update for testing: IPFire 2.27 – Core Update 172. It comes with cryptography improvement for IPsec and OpenVPN, as well as security improvements under the hood, a plethora of package updates and various bugs fixed across the place.

BSD

=> ↺ JRG Systems – Migrating to Vultr from Oracle Cloud

• After a bit of “soul searching” and annoyances from Oracle Cloud that began to pile up (the traffic management layer is very Oracle-ish), I migrated away from the free tier of Oracle Cloud’s offering to a small VM from Vultr. This time I installed OpenBSD.

• Running a small webserver with OpenBSD is a breeze! I always knew this in an abstract sense but never deployed one myself. Basically, all it took was spinning up the instance on vultr.com, installing a couple packages, setting up the webserver httpd in base, and using acme-client (also in base) to pull down a certificate for the website.

=> ↺ GoToSocial on OpenBSD, a Fediverse adventure

• In early 2019, I got fed up with Twitter Ads and recommendations etc. So I started looking for alternatives and read about Mastodon. As I was especially looking for OpenBSD news, tricks etc, I finally landed on bsd.network. It turned out to be a really nice place to hang out ; and not BSD-centric at all. People there are great. And MastoAdmins are kind and caring people.

• A couple of years later, I decided that I would host my own instance on the Fediverse. And the journey began.

• There were no particular reasons to host my on instance server. And as one say: only because you can does not mean you should. But this is how I learn things.

• So I created a bunch of accounts in various Fediverse instances using Mastodon, Friendica, PixelFed, Misskey, GNUsocial, Pleroma. I also installed Honk and GoToSocial. Then I started testing how they all worked together. And I finally decided to go with GoToSocial .

Fedora Family / IBM

=> ↺ Irving Wladawsky-Berger: The Current State of Service Science

• On October 17, the National Academy of Engineering (NAE) conducted an online forum on Service Systems Engineering in the Era of Human-Centered AI. “With AI advances poised to drive service system productivity and quality – similar to the way previous generations of technology revolutionized agriculture and manufacturing productivity and quality – it is time to take stock for industry-academic-and-government stakeholders on this important topic,” wrote the NAE in its website.

• The agenda included an opening keynote by retired IBM executive Nick Donofrio. It was followed by four panels on various aspects of service systems, and concluded with an open discussion of the way forward. I was a member of the panel on Evolving Engineering Education. In my prepared remarks, I reflected on the current state of service science and related sociotechnical systems. Let me share my remarks, slightly edited for clarity.

• Service Science, Management and Engineering (SSME) is an initiative launched in IBM’s Almaden Research Lab in the early 2000s in partnership with a number of universities as an interdisciplinary field of study aimed at applying science, technology and innovation to the service sector of the economy. The service sector is the largest in most economies around the world. At the time, services already accounted for over 70% of GDP and jobs in advanced economies, as well as an increasing portion of the revenues of many companies, including close to 60% of IBM’s revenues.

• The board also features up to 16MB XSPI NOR flash, a MicroSD card socket, a USB 2.0 OTG port with support for a 2-lane MIPI CSI camera module, and two 20-pin GPIO headers for expansion. It measures just 51 x 21mm, or in other words, is about the size of a Raspberry Pi Pico W.

=> ↺ Using I²C Sensors With Any Linux Via USB And IIO | Hackaday

• Hooking up I2C sensors is something which is generally associated with microcontrollers and SBCs, yet it’s very easy to use such I2C sensors from basically any system that runs Linux. After all, I2C (that is, SMBus) is one of the interfaces that is highly likely to be used on your PC’s mainboard as well as peripherals. This means that running our own devices like the well-known BME280 temperature, pressure and humidity sensor, or Si1145 light sensor should be a piece of cake.

• In a blog post from a few years ago, [Peter Molnar] explains in detail how to wire up a physical adapter to add a USB-connected I2C interface to a system. At its core is the ATtiny85 AVR-based MCU, which provides a built-in USB interface, running the I2C-Tiny-USB firmware.

=> ↺ Detect vandalism using audio classification on the Nano 33 BLE Sense | Arduino Blog

• Having something broken into and/or destroyed is an act that most people hope to avoid altogether or at least catch the perpetrator in the act when it does occur. And as Nekhil R. notes in his project write-up, traditional deterrence/detection methods often fail, meaning that a newer type of solution was necessary.

• Unlike other glass breaking sensors, Nekhil’s project relies on a single, inexpensive Arduino Nano 33 BLE Sense and its onboard digital microphone to record audio, classify it, and then alert a property owner over WiFi via an ESP8266-01 board. The dataset used to train the machine learning model came from two sources: the Microsoft Scalable Noisy Speech Dataset for background noise, and breaking glass recorded on the device itself. Both of these were added to an Edge Impulse project via the Studio and split into two-second samples before being processed by a Mel-filterbank Energy (MFE) algorithm.

=> ↺ Binbot 9000 moves to where the trash is | Arduino Blog

• Our modern societies create a lot of garbage, which we can fortunately remove from our homes thanks to local waste management services. But the garbage people won’t come sift through your house for refuse, which forces you to utilize trash bins. Those bins never seem to be nearby when you need them, which is why James Bruton built the Binbot 9000.

• The Binbot 9000 is exactly what it sounds like: a robotic trash can. No longer must the bin remain stationed in some out-of-the-way location. Instead, Binbot 9000 can drive around a home in search of people who need to throw things away.

• There is a common annoyance that seems to plague every reverse engineer and incident responder at some point in their career: wasting time or energy looking at junk code. Junk code is a sequence of bytes that you have disassembled that are not actual instructions executed as part of a program. In addition to wasting time, I’ve seen people get alarmed and excited by the junk code they’ve found. In these cases, it is because they found executable code in a place they weren’t expecting, which led them to believe they had found an exploit or an advanced malware specimen.

It is providing a sort of blueprint for using Bayes factors in forensics for both investigative and evaluative purposes. With R code and free access. I am of course unable to judge of the relevance of the approach for forensic science (I was under the impression that Bayesian arguments were usually not well-received in the courtroom) but find that overall the approach is rather one of repositioning the standard Bayesian tools within a forensic framework.

• Finding flow while coding is sometimes tricky to do – it’s even trickier when encountering ‘someone else’s code’. We’ve all had the experience of reading code and crying, “WAT?!”.

• Working with high ‘wattage’ code is not just unpleasant, it costs time and money. The more WATs a program contains, the scarier it is, and sadly, fear is a flow stopper.

• By contrast, writing low wattage code can facilitate flow by keeping things cognitively comfortable for yourself and other programmers. Let’s start with some high wattage code and Raku-ify it.

• Germany’s federal and state data protection authorities (DSK) have raised concerns about the compatibility of Microsoft 365 with data protection laws in Germany and the wider European Union.

• According to the German watchdog’s report [PDF], which was written after two years of negotiations with Microsoft, the body says that the product “remains in breach” of the General Data Protection Regulation (GDPR).

• The 2020 working group was put together to bring the cloud service into line with the Schrems II decision of the European Court of Justice – and relates to ongoing European concerns about cloud data sovereignty, competition, and privacy rules.

• Under the GDPR, children below the age of 13 are incapable of consenting to their data being collected, while consent may be given by those with parental responsibility for those under 16 but not younger than 13. When platforms do store data on adults, those customers are meant to be able to request the deletion of their records.

• The report adds (translated from the German): “Many of the services included in Microsoft 365 require Microsoft to access the unencrypted, non-pseudonymized data.”

=> ↺ Memory Safe Languages in Android 13 (Google security blog) [LWN.net]

• Over on the Google security blog, Jeffrey Vander Stoep writes about the impact of focusing on using memory-safe languages for new code in Android.

• Google provided investigators with location data for more than 5,000 devices as part of the federal investigation into the attack on the US Capitol.

=> ↺ Political advertising: EU Parliament disagrees on personalised targeting of political messages – Patrick Breyer

• The EU Parliament’s Civil Liberties Committee (LIBE) will vote tomorrow at 12:00 to restrict the use of personal data to target online political advertisements to data explicitly provided for this purpose by citizens with their consent, excluding the use of behavioural and inferred intelligence on citizens. Due to a lack of political agreement there will be a separate vote (“COMP12a”) on whether the use of personal data to target political messages at large scale via direct letters, e-mail and text messages will be restricted or not.

=> ↺ FTX’s Collapse Was a Crime, Not an Accident

• Perhaps most perniciously, many outlets have described what happened to FTX as a “bank run” or a “run on deposits,” while Bankman-Fried has repeatedly insisted the company was simply overleveraged and disorganized. Both of these attempts to frame the fallout obfuscate the core issue: the misuse of customer funds.

• Banks can be hit by “bank runs” because they are explicitly in the business of lending customer funds out to generate returns. They can experience a short-term cash crunch if everyone withdraws at the same time, without there being any long-term problem.

• But FTX and other crypto exchanges are not banks. They do not (or should not) do bank-style lending, so even a very acute surge of withdrawals should not create a liquidity strain. FTX had specifically promised customers it would never lend out or otherwise use the crypto they entrusted to the exchange.

• In reality, the funds were sent to the intimately linked trading firm Alameda Research, where they were, it seems, simply gambled away. This is, in the simplest terms, theft at a nearly unprecedented scale. While the total losses have yet to be quantified, up to one million customers could be impacted, according to a bankruptcy document.

=> ↺ ‘FTX’s Collapse Was a Crime, Not an Accident’

• So in a sense FTX’s implosion had nothing to do with cryptocurrency directly, beyond the fact that no one would have given FTX a nickel if not for the vague belief that “something something crypto” would lead to a windfall.

=> ↺ The Universe of Discourse : Wombat coprolites

• I was delighted to learn some time ago that there used to be giant wombats, six feet high at the shoulders, unfortunately long extinct.

• It’s also well known (and a minor mystery of Nature) that wombats have cubical poop.

=> ↺ Today, in Twitter-Apple Drama

• I heard from a source who spent time working in Twitter’s ad products organization that Apple, until recently, was not just a big advertiser on Twitter, but the largest. The @apple account never posts regular tweets but frequently posts promoted tweets, and Apple heretofore had been a big spender on things like hashflags and custom like buttons, to promote major product introduction events.

• After years of running straight vitriol and opinion masked as news, Dan Andrews was returned as the Premier of Victoria leaving us to ask if Murdoch and the commercial media is losing their influence on swaying elections.

=> ↺ Four British ministries refuse to say if they’ve discussed Assange with U.S.

• Four of Britain’s most powerful government ministries are refusing to say if their officials have met with US authorities to discuss the case of Julian Assange.

• The Home Office, Cabinet Office, Foreign Office, and Ministry of Justice all recently failed to tell parliament about any potential contact with their US counterparts on the issue of the WikiLeaks founder.

• The refusals raise further suspicions about the politicisation of Assange’s legal case. Britain is part of the US-dominated “Five Eyes” intelligence alliance and very close to the American government, which is demanding Assange’s extradition.

Digital Restrictions (DRM)

=> ↺ Sideloading is the most important feature of any SmartPhone

• I’ve written serious articles about the issue. I’ve written satire mocking Apple’s undeniable fear of “Sideloading”. I’ve joined with the Free Software Foundation Europe in signing an open letter about it.

• Now, let me be crystal clear: “Sideloading” is the most critical and valuable feature of any smartphone or computer. Period. Full stop.

• [...]

• Sideloading is the act of installing software, whatever software you want, on a real computer (which includes pocket computers, like smartphones).

• Seems simple and obvious, right? If you own a computer (or a smartphone), you should be able to install software on it.

• Apple and Google both (strongly) disagree with that. While Google has allowed “sideloading” on Android since the beginning, they have recently begun taking steps to limit that in the future.

=> ↺ I cast “Cleave”

• One of the optional rules we’ve been using since the DMG first came out in 2014 has been cleave. Sometimes we go long stretches of not remembering it, other times it is used a lot.

=> ↺ Advent jam 🕯️

• When I was a child, opening a door on an advent calendar didn’t get you any loot. It just revealed a seasonal picture: some holly, perhaps, or an angel. By the time I was an adult, chocolate was expected. When I had children, we got them one with Lego. More recently I was given one with whisky miniatures (and so drank far more whiskey in a month than I ordinarily would do in a year).

=> ↺ Bonus-action potion quaffing

• Some people use a house rule that potions of healing only take a bonus action to quaff. Don’t they know how painful it is to get healed by such drinks? It hurts like a mother as your body relives the injuries backwards and digs you up, yanks out the coffin nails, knits you up, stitches you up, burns you up like a modern swindler.

• Brewing the potions from the petals of blood viola flowers is a time-consuming process, too, and expensive. You need twenty-five petals for a single small bottle. But then it glints like dawn gold over the red seas of a mothworld. A sickly-sweet taste of root celery, jasmine, cardamom-thrice-steeped, and above all a lingering red viola aftertaste that takes days to go away.

=> ↺ Authentication gateway with SSH on OpenBSD

• A neat feature in OpenBSD is the program authpf, an authenticating gateway using SSH.

• Basically, it allows to dynamically configure the local firewall PF by connecting/disconnecting into a user account over SSH, either to toggle an IP into a table or rules through a PF anchor.

=> ↺ The pandemic is over

• I got a french press a few weeks after the start of the pandemic.

• I loved the thing, but since it takes quite a bit of time to brew with it and it’s extremely manual for each step, I worried when life got back to normal I wouldn’t be able to replace my pour-over with it for my morning coffee. Little did I know the pandemic was going to last a couple more years.
