Vim 9.0 : vim online

tuxmachines.org - Tor, 06/28/2022 - 22:03

After many years of gradual improvement Vim now takes a big step with a major release. Besides many small additions the spotlight is on a new incarnation of the Vim script language: Vim9 script.
The previous release was version 8.2 in December 2019. Since the latest source code is always available on GitHub, many have already picked up later patch versions (there are more than 5000 of them!). Therefore the changes have already been tried out by many users. On top of that bugs have been fixed, security issues have been addressed, and many tests have been added. Code coverage has been dramatically increased. This version is more reliable than any before.

    In this final article that concludes my series about best practices for effective site reliability engineering (SRE), I cover some of the practical applications of site reliability engineering.

    There are some significant differences between software engineering and systems engineering.

  • Scanning container image vulnerabilities with Clair

    When Red Hat started releasing products as container images, we decided we needed to build them the same way they were built upstream, which is by building them from Dockerfiles. This means we build fewer RPMs than we used to, and instead we pull in software dependencies from outside of the RPM / DNF ecosystem. It took us some time to get our security data to the same standard as it was for RPM, but that time has arrived, and you can now consume security data for Red Hat container images the same way you do for Red Hat RPMs.

  • David Cantrell: rpminspect-1.10 released

I'll do that now here in one fell swoop, together with tickets that were approved during the last week. (I tried to filter out tickets that were announced somewhere but not closed, but I might have missed something, so please excuse any duplication.)

Debian and The History of Debian Linux Distribution

tuxmachines.org - Tor, 06/28/2022 - 20:20

Since its inception in 1993, Debian has grown into one of the most robust, stable, and widely used Linux distributions. Debian is a free and open-source community-driven project that is actively developed & maintained by a community of vibrant developers from around the world.

Debian is a portmanteau that blends two words: Deb (Short for Debra, Ian’s wife) and Ian, its creator. Debian is a fast, lightweight, and robust distribution that is dubbed the ‘The mother of all Ubuntu distributions‘.

Yes, Ubuntu is derived from Debian Linux and, as a result, this has yielded a myriad of Linux distributions based on Ubuntu such as Linux Mint, POP! OS and Elementary OS.

We already have an informative guide on the history of Ubuntu, so please check it out.

[$] A "fireside" chat

LWN.net - Tor, 06/28/2022 - 20:20
In something of an Open Source Summit tradition, Linus Torvalds and Dirk Hohndel sit down for a discussion on various topics related to open source and, of course, the Linux kernel. Open Source Summit North America (OSSNA) 2022 in Austin, Texas was no exception, as they reprised their keynote on the first day of the conference. The headline-grabbing part of the chat was Torvalds's declaration that Rust for Linux might get merged as soon as the next merge window, which opens in just a few weeks, but there was plenty more of interest there.

Need a free Slack alternative? How to quickly deploy Rocket.Chat

tuxmachines.org - Tor, 06/28/2022 - 20:19

Have you ever needed the ability to add a chat/collaboration tool but didn't want to rely on third-party services or have the budget to pay for a service like Slack? If that sounds like a situation you find yourself in, you'll be happy to know there are plenty of options available.

One such option is Rocket.Chat, which is a free, open-source platform geared toward team communication and collaboration on Windows, macOS, Linux, Android and iOS. The Rocket.Chat server can be deployed to off-the-shelf hardware (either a server or desktop, though server is preferable) and can be connected to from the desktop or even mobile apps (for both Android and iOS).

First off, you can go two routes with Rocket.Chat. You can install and use the server on your own hardware or you can pay for a cloud-hosted plan. The Community edition (which is what we'll be dealing with) is best suited for 100 users. If your organization requires more than that, you should consider either the Pro or Enterprise cloud-hosted option.

    The Homeland Security Systems Engineering and Development Institute, sponsored by CISA and operated by MITRE, has released the 2022 Common Weakness Enumeration (CWE) Top 25 Most Dangerous Software Weaknesses list. The list uses data from the National Vulnerability Database to compile the most frequent and critical errors that can lead to serious vulnerabilities in software. An attacker can often exploit these vulnerabilities to take control of an affected system, obtain sensitive information, or cause a denial-of-service condition. This year’s list also incorporates updated weakness data for recent Common Vulnerabilities and Exposure records in the dataset that are part of CISA’s Known Exploited Vulnerabilities Catalog.

  • When Security Locks You Out of Everything

    Thought experiment story of someone of someone who lost everything in a house fire, and now can’t log into anything

    [...]

    Those risks are in the order of most common to least common, but that doesn’t necessarily mean that they are in risk order. They probably are, but then we’re left with no good way to handle someone who has lost all their digital credentials—computer, phone, backup, hardware token, wallet with ID cards—in a catastrophic house fire.

    I want to remind readers that this isn’t a true story. It didn’t actually happen. It’s a thought experiment.

  • Delaying the inevitable: Implementation of CERT-In’s Cybersecurity Directions gets a piecemeal extension

    On June 27, 2022, the Indian Computer Emergency Response Team (“CERT-In”) issued a notification (No. 20(3)/2022-CERT-In) in relation to the extension of timelines for partial enforcement of Cyber Security Directions of April 28, 2022 (“Directions”) issued under sub-section (6) of section 70B of the Information Technology (“IT”) Act, 2000. The Directions were scheduled to go into effect 60 days from the date of their notification. While the timelines for enforcement of the entire Directions have been extended for Micro, Small and Medium Enterprises (“MSMEs”), for Data Centres, Virtual Private Server (“VPS”) providers, Cloud Service providers and Virtual Private Network (“VPN”) service providers only specific requirements relating to the validation of subscribers/customers details have received a timeline extension. The new date for enforcement of the Directions for such entities and specific requirements is September 25, 2022.

  • CMC Electronics EFB breakout vulnerability | Pen Test Partners

    We’ve been finding vulnerabilities in electronic flight bags for a few years now. Disclosure response from the vendors involved has varied from excellent to radio silence.

    In every case we have tried extremely hard to engage with the vendors involved, even where we were ignored. We asked friendly OEMs and others in the supply chain to help encourage those who wouldn’t respond to us, but their efforts were ignored too.

    In some circumstances, it would be possible to affect take-off performance and landing calculations, resulting in significant safety events such as those here.

Running DOS on a 64-bit OS: A brief guide

tuxmachines.org - Tor, 06/28/2022 - 20:10

There are still ways to run DOS apps under 64-bit Windows and Linux, and a lot of free apps to choose from.

One of the differences between the Microsoft and Apple approaches to maintaining widely used OSes is that Apple is quite aggressive about removing backwards compatibility, while Microsoft tries hard to keep it.

One of the few times Microsoft removed a whole compatibility layer from Windows was with the launch of 64-bit Windows, which went mainstream with Vista in 2007. 64-bit editions of Windows can't run 16-bit apps, whether they're for DOS or Windows.

Enterprising developers, of course, take this kind of thing as a challenge.

There are obvious ways round this, of course. You can run DOS in a virtual machine. It works fine – the problem is that it's very difficult to get anything in or out of it. Modern PCs are also so vastly more powerful than they were in DOS' heyday of the 1980s that you just run a PC emulator, such as DOSBox or the enhanced DOSBox-X.

These programs emulate an entire PC, so you can run games that require long-obsolete hardware such as SoundBlaster cards. DOSBox-X even supports Windows 3.x and Win9x.

  • Install Laravel on Ubuntu 22.04 LTS Jammy JellyFish Linux - Linux Shout

    Tutorial to learn the steps for installing PHP Laravel framework on Ubuntu 22.04 LTS Jammy JellyFish using the command terminal for developing web apps.

    PHP doesn’t need an introduction, it has been around for many years powering web applications that need a dynamic programming language to work but one thing it is not (anymore): modern.

    Programming languages ​​such as Ruby and Python have become increasingly popular, especially in recent years. They are “cool” and appeal better to the next generation of coders. Whereas it is unfortunate PHP is getting a bit old and you can tell. This is exactly where Laravel comes into play. We can consider it as a new generation PHP framework and that’s what makes it so popular. Inspired by Ruby on Rails and .NET, Taylor Otwell created Laravel to get the most out of PHP and to prove that more is possible. Also, he wasn’t satisfied with the other PHP frameworks. They are no longer contemporary. He doesn’t only want to help developers be more productive but also to show that clean programming with PHP can also be fun again.

    In this article, let’s discuss the initial phase to work with Laravel is to install it on Ubuntu-based Linux systems.
