  • Debconf Video Team Sprint – Day 3

    Today has mostly been spent in conversation.

    Jonathan has started to scratch an itch that I share, we need a better tally light solution. When we were using DV switch we had a simple tally light system using (iirc DTR on a) serial port to turn on or off an LED. This was fine because there was always a PC available at each camera running DVCapture.

    Since the move to Voctomix, each camera no longer has it’s own dedicated PC. Instead we have long 50R co-ax cables (remember the days of cheaper-net 10 base-2?) going directly to a PC running VoctoCore…. Yes we still use a serial port to drive a tally light (all be it these days from a USB to serial converter) but we could do so much better.

  • DevConf.CZ 2019 Recap

    DevConf.CZ 2019 wrapped up last weekend and it was a great event packed with lots of knowledgeable speakers, an engaging hallway track, and delicious food. This was my first trip to any DevConf and it was my second trip to Brno.

  • Scott Kitterman: Rise and fall of libclamav

  • SALT is a third-party alternative to LG UP

    Although, currently flashing KDZ files is currently unsupported. You can check out the thread at the link below to download the software, and to leave feedback for the developer as the tool is refined. It works for both GNU/Linux and Windows operating systems, though the developer recommends you use the tool in his FWUL GNU/Linux environment.

  • Eclipse GlassFish Java EE 8 Certified

    GlassFish, and its associated Technology Compatibility Kit (TCK) code, has been fully migrated to Eclipse Foundation stewardship. The new release, Eclipse GlassFish 5.1.0, is now fully Java EE 8 certified, which represents a key step to ensuring backward compatibility of Jakarta EE.

    GlassFish is the reference implementation of Java EE, in other words, the standard from which all other implementations and corresponding customizations are derived. GlassFish was initially created by Sun Microsystems for the Java EE platform and is now sponsored by Oracle, who have a supported version called Oracle GlassFish Server.

  • May we live in interesting times

    In 1966, Robert F Kennedy gave his famous Day of Affirmation Address in Cape Town, which included the allegedly Chinese curse “may you live in interesting times”. This has been widely used since, but is it really an ancient Chinese curse? Much research has been carried out into the origins of this phrase, and while it can be traced back to a speech given by Sir Austen Chamberlain in England in 1936, it has been generally confirmed and accepted by many to not be of Chinese origin. As a result, I’m quite happy to live in interesting times – preferably working in an interesting role, in an interesting company, in an interesting industry and surrounded by interesting people. Working at SUSE, as part of the OpenStack industry, I get to tick all of these boxes daily! Incidentally, at the time of writing this, there were 155 roles open on the SUSE careers page – why not take a look and see if any are interesting to you?

  • Is time running out for your SAP Linux support?

    In 60 days, SUSE Linux Enterprise Server for SAP Applications 11 SP4 will reach the March 31, 2019 end date for General Support. This means that it’s no longer possible to purchase a Priority Support subscription with the updates, proactive fixes for bugs and security vulnerabilities, and unlimited technical support that you depend on. More than likely, your SAP systems and services are critical to your business operations, so it’s equally critical that you maintain Linux support for those systems.
    If you’re no longer running your systems on SUSE Linux Enterprise Server for SAP Applications 11 SP4, or have a plan to maintain support with Long Term Service Pack Support (LTSS) then you’re already ahead of the game. Just skip the rest of this blog and enjoy your day. If, on the other hand, you’re wondering what to do next then read on to understand your options.

    Graywalkers: Purgatory from developer Dreamlords Digital has me itching to try it out with a blending of turn-based XCOM-like combat with a supernatural post-apocalyptic theme.

  • In Thrusty Ship your main enemy is yourself and your throttle finger

    Thrusty Ship takes the basic gameplay of classics like Lunar Lander (and many others) with you fighting against gravity and turns it into a challenging and fun battle against your fuel gauge.

  • Unity 2019.1 Beta Deprecates Linux x86, Offers Up Many Vulkan & Linux Improvements

    Unity Tech has put out their first public beta of the upcoming Unity 2019.1 game engine update. There's some notable work on both the Linux and Vulkan fronts.

    Unity 2019.1 beta headlining features include incremental garbage collection support, implementing more GPU lightmapper functionality, particle improvements, and a number of enhancements to the Android platform support. For game developers making use of Unity there are also editor improvements with a number of new features as well as H.265 video transcode, NVIDIA OptiX AI denoiser, and other bits

  • Slay the Spire Now Available for Linux and Windows

    Slay the Spire has been available in Early Access for quite a while, but the game has finally been released in its full form - and stands out compared to pretty much anything else on the market. Roguelikes have been a giant part of the industry for a decade now too, but you don't really see these things combined in a mini-game - let alone in a full-fledged game. The game combines a bit of JRPG mechanics with it as well thanks to its turn-based nature and allows you to build new decks and learn as you go. If you find that a certain attack type is weak against one enemy type, you'll want to switch it up - but maybe find that your new attack setup isn't much more effective. Then you find that by combining various cards together, you get a more effective turn and wind up unlocking the mystery behind a certain enemy.

  • Night of the Blood Moon Now Available on Steam For Linux and Windows PC

    With the rise of rogue-like games over the past decade, the sub-genre has become oversaturated to many. Most games have aimed at making them more accessible, but Blood Moon aims to do things a bit differently. The goal of the developers is to make things challenging and more rewarding. The game's premise is unique too in that it has you fighting in a dream world and destroying all of the cute and sometimes terrifying creatures you see in the dream realm. You can kill as many of them as you want and unlock items, skills, or even helper pets. They act a bit like a third non-playable character in a fighting game in that they can help you briefly and save your bacon, but aren't going to give you a game-breaking adventure.

  • Major Update Released for MachiaVillain on PC, Mac and Linux

    Good Shepherd Entertainment and independent developer Wild Factor have released a shocking new content update for the evil mansion management strategy game MachiaVillain on Windows PC, Mac and Linux.

    MachiaVillain’s new update adds electric fields to your hellish homestead that can be used to power new tools and abilities. Set up alarms, jam mobile phones to keep victims from calling for help, and wield the Finger of Evil to zap enemies or give a boost to your minions.

  • Mage's Initiation adventure/RPG out now for Win / Mac / Linux

  • 19 days of productivity in 2019: The fails

    There seems to be a mad rush at the beginning of every year to find ways to be more productive. New Year's resolutions, the itch to start the year off right, and of course, an "out with the old, in with the new" attitude all contribute to this. And the usual round of recommendations is heavily biased towards closed source and proprietary software. It doesn't have to be that way.

    Part of being productive is accepting that failure happens. I am a big proponent of Howard Tayler's Maxim 70: "Failure is not an option—it is mandatory. The option is whether or not to let failure be the last thing you do." And there were many things I wanted to talk about in this series that I failed to find good answers for.

    So, for the final edition of my 19 new (or new-to-you) open source tools to help you be more productive in 2019, I present the tools I wanted but didn't find. I am hopeful that you, the reader, will be able to help me find some good solutions to the items below. If you do, please share them in the comments.

  • Lenovo’s 4K Yoga Chromebook C630 Is Available to Order

    While certain Chrome OS devices already come with high-resolution displays—like the Pixelbook and Pixel Slate—there’s hasn’t been one with a 4K display. Until the Lenovo Yoga Chromebook C630, that is. And now you can buy one.

    We can talk about whether you need a 4K display in your Chromebook (read: you probably don’t), but at the end of the day, there’s always an argument for just how damn good a display looks when it’s absolutely packed with pixels. I’m sure this one is no exception.

  • Native backup and restoring of Linux containers in Crostini targeted for Chrome OS 74

    While using Linux on a Chromebook is helpful, if something happens to the Linux container, you could easily lose all of your installed apps, data, and settings.

Linux Kernel Getting New Option So SSBD Isn't Over-Protective - Helping Performance

Filed under
Linux
Security

For the Linux kernel's Speculative Store Bypass Disable (SSBD) handling for Spectre Variant 4 protection is support for processes opting into force disabling of speculation via a prctl() interface. Currently when speculation is disabled, that is carried through to new processes started via the execve() system call. But a new bit will allow clearing that state when a new program is started by a process otherwise relying upon PR_SPEC_DISABLE, in what will help the performance in such cases.

Queued for introduction to the mainline Linux kernel is a new PR_SPEC_DISABLE_NOEXEC option for prctl as part of the Speculative Store Bypass Disable options but where the state is cleared on execve() calls. The premise is that programs opting into disabling speculation are doing so, but programs that aren't vulnerable to the speculation-related misfeatures normally aren't checking to see that the PR_SPEC_ENABLE bit is set rather just assuming the status quo. Thus with the current PR_SPEC_DISABLE behavior, programs spawned via execve() may be protected when they really don't need to be and carrying with that the added performance overhead.

The D in SystemD stands for Danger, Will Robinson! Defanged exploit code for security holes now out in the wild

Filed under
Linux
Security

Those who haven't already patched a trio of recent vulnerabilities in the Linux world's SystemD have an added incentive to do so: security biz Capsule8 has published exploit code for the holes.

Don't panic, though: the exploit code has been defanged so that it is defeated by basic security measures, and thus shouldn't work in the wild against typical Linux installations. However, Capsule8 or others may reveal ways to bypass those protections, so consider this a heads-up, or an insight into exploit development. Google Project Zero routinely reveals the inner magic of its security exploits, if you're into that.

Back to SystemD.

In mid-January, Qualys, another security firm, released details about three flaws affecting systemd-journald, a systemd component that handles the collection and storage of log data. Patches for the vulnerabilities – CVE-2018-16864, CVE-2018-16865, and CVE-2018-16866 – have been issued by various Linux distributions.

Exploitation of these code flaws allows an attacker to alter system memory in order to commandeer systemd-journal, which permits privilege escalation to the root account of the system running the software. In other words, malware running on a system, or rogue logged-in users, can abuse these bugs to gain administrator-level access over the whole box, which is not great in uni labs and similar environments.

Nick Gregory, research scientists at Capsule8, in a blog post this week explains that his firm developed proof-of-concept exploit code for testing and verification. As in testing whether or not computers are at risk, and verifying the patches work.

  • Linux Kernel hid_debug_events_read() Function Local Denial of Service Vulnerability [CVE-2019-3819]

    A vulnerability in the hid_debug_events_read() function of the Linux Kernel could allow a local attacker to cause a denial of service (DoS) condition on a targeted system.The vulnerability exists in the hid_debug_events_read() function, as defined in the drivers/hid/hid-debug.c source code file of the affected software. The vulnerability is due to an infinite loop condition that may occur when user-supplied input with certain parameters is passed from a userspace. An attacker with root privileges could exploit this vulnerability by executing a program that submits malicious input to the targeted system. A successful exploit could cause the system to lock, resulting in a DoS condition.Kernel.org has not confirmed the vulnerability, and software updates are not available.

Want a bit of privacy? Got a USB stick? Welcome to TAILS 3.12

Filed under
Security
Debian

The Linux distro for the security-conscious has been updated with a fresh USB installation method.

Hot on the heels of Apple's latest privacy blunder, The Amnesic Incognito Live System (TAILS) has emitted version 3.12.

The big news this time around is the arrival of a USB image alongside the usual ISO. ISOs, handy for burning to a DVD or spinning up a virtual machine, are not so good when it comes to one of TAILS' strengths – running Linux without a trace.

The faff of needing a couple of USB sticks and around three hours of spare time is gone with this release. A single 8GB USB stick is sufficient to handle the 1.2GB download and TAILS reckons that the whole process should take an hour and a half.

A swift download and burn to USB using Etcher and a user is up, running and able to enjoy the discretion afforded by the Debian-based distro and the Tor network.

Fedora’s gaggle of desktops

There are 38 different desktops or window managers in Fedora 31. You could try a different one every day for a month, and still have some left over. Some have very few features. Some have so many features they are called a desktop environment. This article can’t go into detail on each, but it’s interesting to see the whole list in one place. To be on this list, the desktop must show up on the desktop manager’s selection list. If the desktop has more than one entry in the desktop manager list, they are counted just as that one desktop. An example is “GNOME”, “GNOME Classic” and “GNOME (Wayland).” These all show up on the desktop manager list, but they are still just GNOME. Read more

Programming: 'DevOps', Caddyfile, GCC 8.4 RC and Forth

  • A beginner's guide to everything DevOps

    While there is no single definition, I consider DevOps to be a process framework that ensures collaboration between development and operations teams to deploy code to production environments faster in a repeatable and automated way. We will spend the rest of this article unpacking that statement. The word "DevOps" is an amalgamation of the words "development" and "operations." DevOps helps increase the speed of delivering applications and services. It allows organizations to serve their customers efficiently and become more competitive in the market. In simple terms, DevOps is an alignment between development and IT operations with better communication and collaboration. DevOps assumes a culture where collaboration among the development, operations, and business teams is considered a critical aspect of the journey. It's not solely about the tools, as DevOps in an organization creates continuous value for customers. Tools are one of its pillars, alongside people and processes. DevOps increases organizations' capability to deliver high-quality solutions at a swift pace. It automates all processes, from build to deployment, of an application or a product.

  • How to solve the DevOps vs. ITSM culture clash

    Since its advent, DevOps has been pitted against IT service management (ITSM) and its ITIL framework. Some say "ITIL is under siege," some ask you to choose sides, while others frame them as complementary. What is true is that both DevOps and ITSM have fans and detractors, and each method can influence software delivery and overall corporate culture.

  • New Caddyfile and more

    The new Caddyfile enables experimental HTTP3 support. Also I’ve added a few redirects to my new domain. All www prefix requests get redirected to their version without www prefix. My old domain nullday.de redirects now to my new domain shibumi.dev. Also I had to add connect-src 'self' to my CSP, because Google Lighthouse seems to have problems with defalt-src 'none'. If just default-src 'none' is being set, Google Lighthouse can’t access your robot.txt. This seems to be an issue in the Google Lighthouse implementation, the Google Search Bot is not affected.

  • Content Addressed Vocabulary

    How can systems communicate and share meaning? Communication within systems is preceded by a form of meta-communication; we must have a sense that we mean the same things by the terms we use before we can even use them. This is challenging enough for humans who must share meaning, but we can resolve ambiguities with context clues from a surrounding narrative. Machines, in general, need a context more explicitly laid out for them, with as little ambiguity as possible. Standards authors of open-world systems have long struggled with such systems and have come up with some reasonable systems; unfortunately these also suffer from several pitfalls. With minimal (or sometimes none at all) adjustment to our tooling, I propose a change in how we manage ontologies.

  • Excellent Free Tutorials to Learn Forth

    Forth is an imperative stack-based programming language, and a member of the class of extensible interactive languages. It was created by Charles Moore in 1970 to control telescopes in observatories using small computers. Because of its roots, Forth stresses efficiency, compactness, flexible and efficient hardware/software interaction. Forth has a number of properties that contrast it from many other programming languages. In particular, Forth has no inherent keywords and is extensible. It is both a low level and high level language. It has the interesting property of being able to compile itself into a new compiler, debug itself and to experiment in real time as the system is built. Forth is an extremely flexible language, with high portability, compact source and object code, and a language that is easy to learn, program and debug. It has an incremental compiler, an interpreter and a very fast edit-compile-test cycle. Forth uses a stack to pass data between words, and it uses the raw memory for more permanent storage. It also lets coders write their own control structures. Forth has often being deployed in embedded systems due to the compactness of object code. Forth is also used in boot loaders such as Open Firmware (developed by Sun Microsystems) as well as scientific fields such as astronomy, mathematics, oceanography and electrical engineering.

Unfortunately, until just a few days ago that process didn't include the cover. Instead, covers were inserted manually using Adobe Acrobat.

  • A Week At A Time - Building SaaS #46

    In this episode, we worked on a weekly view for the Django app. We made navigation that would let users click from one week to the next, then fixed up the view to pull time from that particular week. The first thing that I did was focus on the UI required to navigate to a new weekly view in the app. We mocked out the UI and talked briefly about the flexbox layout that is available to modern browsers. From the UI mock up, I changed the view code to include a previous_week_date and next_week_date in the view context so we could change the links to show real dates. From there, we needed a destination URL. I create a new path in the URLconf that connected the weekly URL to the existing app view that shows the week data. After wiring things together, I was able to extract the week date from the URL and make the view pull from the specified day and show that in the UI. Finally, we chatted about the tricky offset calculation that needs to happen to pull the right course tasks, but I ended the stream at that stage because the logic changes for that problem are tedious and very specific to my particular app.
