Consistent security controls and high reliability are common expectations for any systems administrator. How do you deliver both on a network with thousands of servers supporting thousands of engineers? Most off-the-shelf solutions require a compromise in at least one of these areas — and we refused to accept this.

Most systems administrators use the industry-standard Secure Shell (SSH) for accessing systems, and yet many of its special features are not widely leveraged. At Facebook, we take advantage of those features to use SSH in a way that is reliable, secure, and manageable. SSH, more specifically OpenSSH, has a great way to provide both the security and reliability we require: signed certificates with principals.

If you want your list to be included on awesome, try to only include actual awesome stuff in your list. After all, it's a curation, not a collection.

But what is awesome?
Only awesome is awesome
Research if the stuff you're including is actually awesome. Only put stuff on the list that you or another contributor can personally recommend. You should rather leave stuff out than include too much.

OProfile has been around for decades, and for some time was the workhorse of performance profiling on Linux®-based systems, and can serve the same role today. However, OProfile is not included in Red Hat Enterprise Linux (RHEL) 8 beta, and so it may be prudent for OProfile users to start considering alternative tools. Analogous projects which compare very favorably to OProfile in features, ease-of-use, and vitality of the community do exist. One such project is the Linux perf command. Until recently, when compared to OProfile, perf had some drawbacks such as lack of support for Java™ just-in-time (JIT) compiled programs and hardware event mnemonics, but these have been addressed in recent releases. This tutorial offers current OProfile users a roadmap for transitioning from OProfile to perf.

lab interacts with repositories on GitLab, including creating/editing merge requests, issues, milestones, snippets and CI pipelines.

The development team has focused on keeping lab a simple and intuitive command line interface for commands provided in the GitLab API. lab's aim is to provide GitLab users an experience similar to the GitLab WebUI with respect to errors and messages.

If you do a significant amount of programming, you'll probably end up with build artifacts scattered about. sn is a tool to help you find those artifacts.

sn is also a replacement for du. It has nicer output, saner commands and defaults, and it even runs faster on big directories thanks to multithreading.

I'm taking a look at twelve "obscure" window managers.

systemd is, to put it mildly, controversial. Depending on who you ask it's either a complete violation of the UNIX philosophy, a bloated pile of bugs, a complete violation of the elegant simplicity it replaced or, it most cases, some or all of the above.

So why have so many Linux distributions taken to it? Is it as bad as people say? Are the BSD projects right to be avoiding it?

Let's look into the history of UNIX userland bootstrapping and the factors that lead to the creation of systemd, why it's turned out the way it has, and what there is to be learned from it.

In the linux world they can all look the same from the point of view of the user at the keyboard. The differences are in how they interact with each other.

The shell is the program which actually processes commands and returns output. Most shells also manage foreground and background processes, command history and command line editing. These features (and many more) are standard in bash, the most common shell in modern linux systems.

A terminal refers to a wrapper program which runs a shell. Decades ago, this was a physical device consisting of little more than a monitor and keyboard. As unix/linux systems added better multiprocessing and windowing systems, this terminal concept was abstracted into software. Now you have programs such as Gnome Terminal which launches a window in a Gnome windowing environment which will run a shell into which you can enter commands.

The console is a special sort of terminal. Historically, the console was a single keyboard and monitor plugged into a dedicated serial console port on a computer used for direct communication at a low level with the operating system. Modern linux systems provide virtual consoles. These are accessed through key combinations (e.g. Alt+F1 or Ctrl+Alt+F1; the function key numbers different consoles) which are handled at low levels of the linux operating system -- this means that there is no special service which needs to be installed and configured to run. Interacting with the console is also done using a shell program.

Einige Straßenlaternen in Leicester brennen seit Wochen ununterbrochen. Die Stadtverwaltung musste ihre IT-Systeme aufgrund eines Cyberangriffs abschalten.

"Maßnahmen zum Schutz der Privatsphäre wie Ende-zu-Ende-Verschlüsselunug werden ausgerollt, was Tech-Unternehmen daran hindert, Verstöße auf ihren Plattformen zu sehen. Das wird auch unterbinden, dass Strafverfolger an diese Beweise gelangen und sie in Untersuchungen nutzen können, um die schlimmsten Verbrechen wie sexuellen Kindesmissbrauch, Menschenhandel, Drogenschmuggel, Tötungsdelikte, Wirtschaftskriminalität und Terrorismus zu verhindern und verfolgen", erläutert Europol.

Medienpädagoge Daniel Schlep kritisiert, dass der Digitalpakt Technik in die Schulen spülte, aber langfristige Konzepte und echte Kompetenzen fehlen.

So our 2016 Subaru Outback has been having horrible battery drain issues for a couple years now. We got the attached service bulletin recently that explained the issue.

It turns out that the Data Communications Module that powers Subaru's Starlink service (emergency assistance/safety/etc. service) now causes a battery drain because it is trying to talk to a 3G network that is no longer there, and it just tries its little heart out.

Laut einem Gutachten des Landesrechnungshofs wurden für die eingestellte Plattform 8,7 Millionen Euro versenkt. Für das Nachfolgeprojekt stünden bis Ende 2024 insgesamt Mittel in Höhe von 24 Million Euro zur Verfügung

Die App Digitales Amt, die erst vor Kurzem in Vollbetrieb gegangen ist, ist auf Mobiltelefonen mit dem Betriebssystem Android seit Tagen nicht mehr funktionsfähig. Der Fehler bei ID Austria wurde auch seitens der Servicehotline bestätigt. Schuld sei ein Update, das am Freitag ausgerollt wurde, der Fehler soll bald behoben werden. Auch Auswirkungen auf die Arbeit der Untersuchungsausschüsse hat der Bug, gewährt das Digitale Amt doch Akteneinblick.

Die vor allem von ÖVP-Seite geforderte Überwachung von Messengerdiensten soll in einem ersten Schritt die Metadaten betreffen. Dafür notwendig wäre eine Anpassung der auf Grundlage des Telekommunikationsgesetzes bestehenden Verordnung zur Überwachung des Fernmeldeverkehrs, hieß es heute auf APA-Anfrage aus dem Innenministerium.
