Fedora: Flicker-Free Boot and Upcoming Elections

Filed under
Red Hat
  • Fedora Perfecting Their Flicker-Free Boot Experience With A New Plymouth Theme

    The recent release of Fedora 29 the long-desired goal of a flicker-free boot experience to the Linux desktop was finally achieved... Well, assuming you are for now using Intel graphics and set a couple extra settings and don't have any quirky hardware. While all of the key components are in place, for Fedora 30 and beyond they will likely be taking care of the "rough edges" and already there is work on a new Plymouth boot theme for pairing with this flicker-free boot process.

  • New plymouth theme for flickerfree boot

    Since the transition to plymouth is not entirely smooth plymouth by default will wait 5 seconds (counted from starting the kernel) before showing itself so that on systems which boot under 5 seconds it never shows. As can be seen in this video, this leads to a very non-smooth experience when the boot takes say 7 seconds as plymouth then only shows briefly, leading to a kinda "flash" effect while it briefly shows.

    Another problem with the 5 second wait, is now that we do not show GRUB the user is looking at the firmware's bootsplash for not only the often long firmware initialization time, but also for the 5 seconds plymouth waits on top, making it look as if nothing is happening.

    To fix this I've been working on a new plymouth theme which draws a spinner over the firmware boot splash, eliminating the ugly transition from the firmware boot splash to plymouth. This also allows removing the show-delay, so that we provide feedback that something is happening as soon as plymouth starts.

Games: Dead Dungeon, Eons of War, DELTARUNE

Filed under
Gaming
  • Dead Dungeon is a hardcore platformer for those who like a challenge

    Dead Dungeon from developer Alexey Roenko just recently released and it's pretty good, one for those who love a bit of difficult platforming.

  • Eons of War, a space 4x strategy game inspired by Risk, Civilization, and chess will be on Linux

    For those who are keen for some more 4x strategy game, Eons of War looks great and it will come to Linux.

    A recent discovery while endlessly browsing for new Linux games, I sent off a message via internet carrier pigeon (Twitter) to the developer about Linux support. Their reply was great "Yes, definitely supporting Linux as well as Mac and Windows. There's enough interest for all three platforms.".

  • DELTARUNE, the successor to UNDERTALE, unofficially ported to Linux

    The surprise successor to the highly praised indie RPG adventure game UNDERTALE called DELTARUNE has been unofficially ported to Linux by a fan through clever hacks.

    DELTARUNE, or rather its first chapter, was released with a cryptic announcement on http://www.deltarune.com for free on Windows and Mac but a Linux version was sadly not released at launch. However, thanks to a DELTARUNE fan on Reddit, we now have unofficial native port of the game.

    The Reddit user JohnWatson78 posted their port on the DELTARUNE subreddit and afterwards updated their post with instructions on how they managed to make the game run on Linux.

    Essentially, they extracted the officially released version of the game, made sure the files were in the correct places and in lowercase letters and found a compatible GameMaker "runner" executable that could then load the game assets. The main issue was finding a suitable runner file by browsing existing Linux GameMaker ports. You can naturally find the more detailed step-by-step guide in JohnWatson78's Reddit post.

Server Buzzwords: 'Cloudwashing', OpenStack and 'Serverless'

  • Getting Clarity on the Private vs. Public Cloud Decision

    News flash: Private cloud economics can offer more cost efficiency than public cloud pricing structures.

    Private (or on-premises) cloud solutions can be more cost-effective than public cloud options, according to "Busting the Myths of Private Cloud Economics," a report 451 Research and Canonical released Wednesday. That conclusion counters the notion that public cloud platforms traditionally are more cost-efficient than private infrastructures.

    Half of the enterprise IT decision-makers who participated in the study identified cost as the No. 1 pain point associated with the public cloud. Forty percent mentioned cost-savings as a key driver of cloud migration.

    "We understand that people are looking for more cost-effective infrastructure. This was not necessarily news to us," said Mark Baker, program director at Canonical.

  • ​OpenStack: Beyond the cloud

    Kata "Containers" is something of a misnomer. Rather than true containers, such as LXC, Kara Containers are lightweight VMs designed to feel and perform like containers. Why bother? Eric Ernst, an Kata Containers Architecture Committee member, explained, they "provide the workload isolation and security advantages of VMs."

  • 6 Best Practices for High-Performance Serverless Engineering

    When you write your first few lambdas, performance is the last thing on your mind. Permissions, security, identity and access management (IAM) roles and triggers all conspire to make the first couple of lambdas, even after a “hello world” trial just to get your first serverless deployments up and working. But once your users begin to rely on services your lambdas provide, it’s time to focus on high-performance serverless.

    This release updates dbus and glib together with all dependencies and related packages. Some of them are rebuilt, the rest are upgraded. Glib 2.58.1 can be considered a development threshold because many dependent packages must be caught it up. Below is a list of some typically upgraded packages:

  • Achievement unlocked! I spoke at PythonBrasil[14]

    PythonBrasil is the national Python community conference that happens every year, usually in October, in Brazil.

    I attended PythonBrasil for the first time in 2016, the year we had started PyLadies Porto Alegre. Back then, we were a very small group and I was the only one to go. It was definitely one of the best experiences I ever had, which, of course, set a very high standard for every single tech event I attended afterwards.

    Because of the great time I had there, I wanted to bring more and more women from PyLadies Porto Alegre to experience PythonBrasil in the next editions. So, during the PyLadies Porto Alegre 1st birthday party, I encouraged the other women to submit activities to try and to go to the conference that would happen in Belo Horizonte.

  • Browser Based Open Source Image Optimization Tool Squoosh Comes To Google Lab’s Latest Release

    Open source, browser-based image optimization tool Squoosh is Google’s new Chrome Lab release. This new web tool is meant to make web developers work a lot simpler to optimize web pages. Images loading in a website is usually the reason for them to take so long to load and Squoosh helps web developers shrink the image so that it consumes lesser data. Squoosh can downsize, compress, and reformat images. Its purpose is to make web developers’ work less tedious and hence quicker. Google chrome labs made this tool available offline and said it would be handy to have this tool work offline. Squoosh also supports editing image codecs that are not normally available in the browser.

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.

  • 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

  • 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)

Meet TiDB: An open source NewSQL database

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.
