Security: Updates, Pwn2Own Tokyo and Spyware

Filed under
Security
  • Security updates for Wednesday

    Security updates have been issued by Arch Linux (powerdns and powerdns-recursor), Debian (ceph and spamassassin), Fedora (feh, flatpak, and xen), Red Hat (kernel, kernel-rt, openstack-cinder, python-cryptography, and Red Hat Single Sign-On 7.2.5), and Ubuntu (python2.7, python3.4, python3.5).

  • iPhone X, Samsung Galaxy S9, Xiaomi Mi 6 Hacked At Pwn2Own Tokyo [Ed: All so-called 'phones' nowadays have a back door at the baseband OS, so cracking them and remotely controlling them is trivial, securing them a non-starter.]
  • It’s Amateur Hour in the World of Spyware and Victims Will Pay the Price

    We’re living in the golden age of spyware and government hacking, with companies rushing to join a blossoming billion dollar market. The weakest among us—activists or journalists—will suffer the consequences if we don’t regulate it appropriately.

Trying DragonFlyBSD & FreeBSD On The Intel Core i9 9900K With ASUS PRIME Z390-A

Filed under
Graphics/Benchmarks

Since last month's Intel Core i9 9900K launch for this eight core / sixteen thread processor we have explored its performance for Linux gaming, how the performance and power efficiency go from the Intel 990X to 9900K, the Spectre mitigation costs, and the Intel Coffeelake Refresh performance across various Linux distributions. For those curious about using the new Intel CPUs and Z390 motherboards with one of the BSD operating systems, I spent a few days over the weekend trying out FreeBSD and DragonFlyBSD releases with the i9-9900K and ASUS PRIME Z390-A motherboard combination.

Meet TASBot, a Linux-Powered Robot Playing Video Games for Charity

Filed under
Linux

Can a Linux-powered robot play video games faster than you? Only if he takes a hint from piano rolls...and doesn't desync.

Let me begin with a brief history of tool-assisted speedruns. It was 2003. Less than half the developed world had internet access of any kind, and YouTube hadn't been created yet. Smartphones were rare and nascent. Pentium III processors still were commonplace, and memory was measured in megabytes. It was out of this primordial ooze that an interesting video file circulated around the web—an 18MB .wmv labeled only as a "super mario bross3 time attack video" [sic]. What followed was an absolutely insane 11-minute completion of the game by someone named Morimoto replete with close calls, no deaths and Mario destroying Bowser after apparently effortlessly obtaining 99 lives. The only other context was a link to a page written in Japanese, and the rough encoding that Windows Media Video format was known for in that era made it difficult for casual viewers to observe that it was an emulator recording rather than the output of a real Nintendo Entertainment System (NES) console.

  • Your Privacy Focused Holiday Shopping Guide

    The lyrics to “Santa Claus Is Comin’ to Town” detail an omniscient Saint Nicholas. But in 2018 — in an era of always-listening products and apps — the lyrics might as well be detailing the latest connected device.

    This holiday season, Mozilla is helping consumers identify which connected products are secure and trustworthy — and which aren’t. The goal: help consumers shop for gifts based on how well they protect the privacy and security of their friends and family, in addition to traditional factors like a product’s price and performance.

KDE and GNOME: NVIDIA, Krita/Atelier and GSoC Mentors Summit 2018

  • NVIDIA Working On An EGLStreams Back-End For KDE On Wayland

    With no recent activity on the NVIDIA-led Unix device memory allocation work that all developer communities could get behind to supersede GBM and EGLStreams for use by Wayland compositors, NVIDIA is working on an EGLStreams back-end for KDE's KWin compositor.

    Similar to the work done on an EGLStreams back-end for GNOME and other EGLStreams work by the smaller Wayland compositors, a NVIDIA engineer is now officially working on an EGLStreams back-end for KWin so that the NVIDIA proprietary driver would play well with KDE on Wayland. Up to now KWin has only supported the Mesa GBM interfaces. KDE developers have said they wouldn't invest in developing an EGLStreams back-end, but that they wouldn't be opposed if say NVIDIA would contribute and maintain the code -- that's what is happening now.

  • Shop update! Digital Atelier and a new USB-Card

    And we’ve also created a new USB-card, with the newest stable version of Krita for all OSes. Includes Comics with Krita, Muses, Secrets of Krita and Animate with Krita tutorial packs.

  • GSoC Mentors Summit 2018

    I represented GNOME, sadly alone because the other selected mentor didn’t get the US visa in time. This was my first trip out of India and I couldn’t plan it properly1, so I went there for just the two conference days.

Graphics: Screen Tearing, Wayland Alpha Compositing Protocol, AMDGPU

Graphics/Benchmarks
  • What Is Screen Tearing and How to Get Rid of It on Linux

    Unfortunately for Linux fans, screen tearing is, and has been, a persistent annoyance that doesn’t seem to be going anywhere. There are a couple of factors enabling the longevity of the screen tearing issue.

    First, and probably most obviously, is the dated, broken, and bloated X server. Even with the progress of Wayland, X is here to stay for the immediate future. Next is the strange and inconsistent graphics driver picture. One of the biggest offenders in causing screen tearing is also the most popular GPU manufacturer on Linux, NVIDIA. Throw in different desktop environments with their own display settings and compositors, and you have a real mess.

    These methods will hopefully eliminate screen tearing in most situations, but it’s impossible to provide a one-size-fits-all solution, thanks to the amount of variables involved. Try what applies to your system, and keep in mind that there might be new factors involved.

  • Collabora Revives Work On Alpha Compositing Protocol For Wayland

    Collabora's Scott Anderson has revived work on the alpha compositing protocol for Wayland, which is based upon the work done by Google on this functionality for Chromium on Wayland.

    The Wayland Alpha Compositing Protocol is intended to control the alpha compositing and blending of surface contents within a Wayland environment. This experimental protocol allows for advanced blending and alpha operations on Wayland surfaces (wl_surface) and Google's work on it dates back at least two years.

  • Radeon Linux Driver Preparing Adaptive Backlight Management (ABM)

    The "AMDGPU" Radeon Linux kernel graphics driver is preparing support for "Adaptive Backlight Management" as a backlight power-savings feature for laptops.

    Adaptive Backlight Management reduces the backlight level in an effort to save power but increases the pixel contrast and luminance to improve image quality and readability under the lower light condition.

Meet TiDB: An open source NewSQL database

Filed under
Server
OSS

As businesses adopt cloud-native architectures, conversations will naturally lead to what we can do to make the database horizontally scalable. The answer will likely be to take a closer look at TiDB.

TiDB is an open source NewSQL database released under the Apache 2.0 License. Because it speaks the MySQL protocol, your existing applications will be able to connect to it using any MySQL connector, and most SQL functionality remains identical (joins, subqueries, transactions, etc.).

Step under the covers, however, and there are differences. If your architecture is based on MySQL with Read Replicas, you'll see things work a little bit differently with TiDB. In this post, I'll go through the top five key differences I've found between TiDB and MySQL.

Is your startup built on open source? 9 tips for getting started

Filed under
OSS

When I started Gluu in 2009, I had no idea how difficult it would be to start an open source software company. Using the open source development methodology seemed like a good idea, especially for infrastructure software based on protocols defined by open standards. By nature, entrepreneurs are optimistic—we underestimate the difficulty of starting a business. However, Gluu was my fourth business, so I thought I knew what I was in for. But I was in for a surprise!

Every business is unique. One of the challenges of serial entrepreneurship is that a truth that was core to the success of a previous business may be incorrect in your next business. Building a business around open source forced me to change my plan. How to find the right team members, how to price our offering, how to market our product—all of these aspects of starting a business (and more) were impacted by the open source mission and required an adjustment from my previous experience.

A few years ago, we started to question whether Gluu was pursuing the right business model. The business was growing, but not as fast as we would have liked.

An Everyday Linux User Review Of Elementary OS 5.0 Juno

Filed under
Reviews

Elementary OS is currently riding high in the Distrowatch rankings and it has been a while since my last review so I thought it was high time I took another look.

The tag line at the top of the Elementary OS website reads as “The fast, open and privacy respecting replacement for Windows and macOS”.

In this review I am going to examine this claim in depth as well as other claims such as “Apps you need, without the ones you don’t”. The website states that the applications have been carefully considered to cater for your everyday needs so you can spend more time using your computer and less time cleaning up bloatware.

Without further ado lets separate the fact from the fiction and explore Elementary OS with a virtual magnifying glass befitting a well known sleuth. After all it is “Elementary” my dear Watson. (Sorry, couldn’t resist).

KDE neon upgrade - From 16.04 to 18.04

I am quite happy with the KDE neon upgrade, going from the 16.04 to the 18.04 base. I think it's good on several levels, including improved hardware support and even slightly better performance. Plus there were no crashes or regressions of any kind, always a bonus. This means that neon users now have a fresh span of time to enjoy their non-distro distro, even though it's not really committing to any hard dates, so the LTS is also only sort of LTS in that sense. It's quite metaphysical. On a slightly more serious note, this upgrade was a good, positive experience. I semi-accidentally tried to ruin it, but the system recovered remarkably, the post-upgrade results are all sweet, and you have a beautiful, fast Plasma desktop, replete with applications and dope looks and whatnot. I'm happy, and we shall bottle that emotion for when the need arises, and in the Linux world it does happen often, I shall have an elixir of rejuvenation to sip upon. KDE neon, a surprisingly refined non-distro distro. Read more

Games: Starsector, Squally, Where The Water Tastes Like Wine: Fireside Chats, 103

  • Open-world single-player space-combat RPG 'Starsector' has a major new release out and it's awesome
    Starsector (formerly "Starfarer") is a game that I've followed for quite a few years now, one I personally purchased many years ago and the latest release is a big one. I've tested it at various points over the years, always coming away impressed by the visual design just as much as the gameplay. The spaceship design really is quite incredible. Thankfully, the issues that plagued the Linux version (for me) in the past are gone. Multi-monitor support has vastly improved, with it not messing with my secondary monitor and going fullscreen correctly on my primary monitor. That alone, is a big deal for me and it's so much nicer.
  • Squally now has the Early Access release on Linux with the Hexus card mini-game available
    Squally is what they're calling a 2D puzzle RPG, which is supposed to teach you "video game hacking" without needing prior experience and no "boring lessons".
  • Where The Water Tastes Like Wine: Fireside Chats, a free standalone adventure is out
    Where The Water Tastes Like Wine: Fireside Chats acts as a free standalone companion to Where The Water Tastes Like Wine and it's out with Linux support.
  • First-person mystery adventure '103' will have Linux support at release
    103 is a rather stylish and intriguing first-person mystery adventure that's releasing next month and it will have Linux support at release. A game we covered previously as it was on Kickstarter, they managed to hit over their funding goal in in September by other seven thousand Australian dollars so they did quite well. In reply to a user question on Steam earlier this month, the developer noted that the Linux version will in fact be available at release so that's some rather nice news to see them so positive about it.

Linus Torvalds Comments On STIBP & He's Not Happy - STIBP Default Will End Up Changing

It turns out that Linus Torvalds himself was even taken by surprise with the performance hit we've outlined on Linux 4.20 as a result of STIBP "Single Thread Indirect Branch Predictors" introduction as well as back-porting already to stable series for cross-hyperthread Spectre V2 protection. He doesn't want this enabled in full by default. All of the benchmarking I've been doing the past few days to shine the light on the Linux kernel's STIBP addition appears to be paying off. My tests have found Linux 4.20 to incur significant performance penalties in many workloads -- in fact, more so than some of the earlier Spectre and Meltdown mitigations -- and STIBP is already being back-ported to stable series like Linux 4.19.2. PHP, Pythom, Java, and many other workloads are measurably affected and even the gaming performance to some extent. Read more
