FreeBSD 12.1 Beta

2019-09-21 20:55:12

FreeBSD 12.1-BETA1 Now Available The first BETA build of the 12.1-RELEASE release cycle is now available. FreeBSD 12.1 Beta Released With Security Fixes, Pulls BearSSL Into Base FreeBSD 12.0 is already approaching one year old while FreeBSD 12.1 is now on the way as the next installment with various bug/security fixes and other alterations to this BSD operating system. FreeBSD 12.1 has many security/bug fixes throughout, no longer enables "-Werror" by default as a compiler flag (Update: This change is just for the GCC 4.2 compiler), has imported BearSSL into the FreeBSD base system as a lightweight TLS/SSL implementation, bzip2recover has been added, and a variety of mostly lower-level changes. More details can be found via the in-progress release notes. read more

Graphics: DXVK, Nouveau

2019-09-21 20:48:47

DXVK 1.4 Released With Updates Against Direct3D 11.4, Other Improvements In time for any weekend gaming is the release of DXVK 1.4 as the latest big update to this Direct3D 11 over Vulkan implementation to boost the D3D11 Windows gaming performance with the likes of Wine and Valve's Steam Play (Proton). With DXVK 1.4 the Direct3D interfaces have been updated against D3D11.4, the latest D3D11 revision shipped by Windows 10 Build 1903. This update brings new API features but DXVK isn't yet supporting some of the optional features like tiled resources and conservative rasterization. Nouveau Finally Lands SPIR-V Support As Part Of OpenCL Push Going back to December 2017 we've been tracking the Red Hat led effort on improving Nouveau's OpenCL compute support that involves adding NIR/SPIR-V support and improvements to the Clover Gallium3D state tracker. To much surprise, this morning the SPIR-V support for this open-source NVIDIA driver was merged for Mesa 19.3. read more

DXVK 1.4 released boosting this Vulkan layer to support D3D 11.4

2019-09-21 20:44:36

Tags: Wine, Vulkan, New ReleaseDeveloper Philip Rebohle has pushed out another major release of DXVK, the Vulkan to D3D layer used together in Wine and Steam Play. Boasting a new feature set that pumps up the available Direct3D support to 11.4. However, certain optional features are not currently supported like Tiled Resources, Conservative Rasterization and Rasterizer Ordered Views but they may be added if ever needed. This should fix a crashing issue with Plants vs Zombies - Battle for Neighborville, which requires at least D3D 11.3. Additionally, support for DXGI (Microsoft DirectX Graphics Infrastructure) was boosted up to version 1.5 which allows applications/games to check for HDR support but DXVK itself does not currently support HDR. Some games seem to need the interface for HDR to be there even if not used. You should also find the Rockstar Game Launcher working better with this update to DXVK, with new support for GDI interop with DXGI surfaces. Although the launcher does need some other Wine fixes due to a bug in Wine's Direct2D support. Some resource mapping improvements were also made with the "d3d11.allowMapFlagNoWait" option enabled by default, possibly resulting in some games performing better. Developer Rebohle asked if you see regressions, to try setting "d3d11.allowMapFlagNoWait = False" in the DXVK config fixes it when reporting a bug. There should also be some possible performance improvements. One such change is games that make heavy use of Deferred Contexts with both Dark Souls III and Sekiro: Shadows Die Twice being mentioned as hopefully improved. There's also a possible CPU overhead improvement with more accurate resource tracking. See the full release announcement here.Article from GamingOnLinux.com

Events: Akademy 2019, Embedded Recipes and Raleigh Licensing Seminar

2019-09-21 20:22:24

Akademy 2019 is over. This year Akademy was a little bit different for me. I joined MBition recently to push Open Source and, giving the kind of activity and technologies we use, KDE is an community we can learn a lot from. We have many things in common. MBition decided to sponsor the event at the Supporter level and my colleague Julia König came with me for a couple of days to learn more about these kind of events and this community in particular. We attended to the welcome event, the sponsors dinner and the first days of talks together. During the second day of talks, I introduced the company to the attendees during the sponsors talk. It was also great to see my former employer, Codethink Ltd, as sponsor once again. KDE Mindmap – Akademy 2019 Akademy is over. =/ And now that I have a little of time I will talk to you about a Birds of Feather that I’ve hosted during the Milan edition of Akademy that was the Mindmap of the community. Since I’ve joined KDE I don’t have a clear picture what the structure of the community looks like. And that’s why I hosted this BoF to try to fix that. All the right ingredients in Paris Next week, Collaborans will be in Paris to participate in this year's editions of Embedded and Kernel Recipes, organized by hupstream. Taking place on September 23 & 24, Embedded Recipes is a conference about open source solutions in the embedded world, wether it's latest developments, contributions, tools or platforms. This year, as the very first speaker on the programme, Collaboran Julian Bouzas will be kicking things off with a look at PipeWire, the new framework for handling audio and video streams on Linux. You can read more about his talk below. Early registration for Raleigh Licensing Seminar extended until September 25th We have extended the early registration period of the upcoming Continuing Legal Education Seminar (CLE), to Wednesday, September 25th. The CLE will be held at the Raleigh Convention Center, Raleigh, North Carolina, on October 16th, 2019. read more

Server: Kubernetes and So-Called 'DevOps'

2019-09-21 20:06:19

Kubernetes Project Releases Version 1.16 SUSE, and the SUSE CaaS Platform team in particular, congratulates the Kubernetes Project of the Cloud Native Computing Foundation on the release of Kubernetes 1.16. The most major change in this release is actually a feature that is already in widespread use. Custom Resource Definitions (CRD) are a major foundation of Kubernetes extensibility and are used by many features and projects; however, they have been in beta since version 1.7, over two years ago. They finally graduate to general availability (GA) and stable status in this release, meaning that anyone using the current version of the feature and its API can expect compatibility for any future 1.x release as well as any 2.x release yet to come. The use of open source software in DevOps has become strategic for organizations of all sizes A higher percentage of top performing teams in enterprise organizations are using open source software, according to a survey conducted by DevOps Research and Assessment (DORA) and Google Cloud. Additionally, the proportion of Elite performers (highest performing teams) nearly tripled from last year, showing that DevOps capabilities are driving performance. Kubernetes 1.16 Offers New Promise for IPv6 Cloud Native Deployments Kubernetes, for the un-initiated is a container orchestration platform that is deployed and supported in all the major public cloud provides and is also widely used on-premises as well. Every new Kubernetes update has features that are in alpha, beta and those that have reached general availability. In the 1.16 update, for networking professionals there is one alpha feature that stands above all others : IPv4/IPv6 dual-stack. "If you enable IPv4/IPv6 dual-stack networking for your Kubernetes cluster, the cluster will support the simultaneous assignment of both IPv4 and IPv6 addresses," the Kubernetes feature documentationstates. The dual stack will support both Kubernetes Pods, which represent a set of running containers; as well as Kubernetes Services, which provide a way to abstract an application running on a set of Pods as a network service. The Kubernetes Enhancement Proposal (KEP) that defines the dual-stack feature, notes that Kubernetes has provides support for IPv6-only clusters as alpha features since the Kubernetes 1.9release which debuted in December 2017. No, Kubernetes is Not the New OpenStack, Says Canonical It’s easy to think of Kubernetes as the great disruptor of earlier generations of cloud-native platforms, such as OpenStack. But that view would be just as wrong as assuming that Kubernetes and containers have totally killed off old-school virtual machines. That’s what Stephan Fabel of Canonical had to say in an interview about the past, present and future of Kubernetes and other cloud-native technologies within the enterprise. [...] As a result of these differences, Fabel says OpenStack and Kubernetes each serve distinct types of workloads. For example, OpenStack might appeal to telcos, which are “more prone to adopting configuration management type approaches, where workloads have to be stateful and long-running.” Kubernetes, meanwhile, is better-suited for workloads that are deployed as REST- or HTTP-based services. To help prove his point about the continued relevance of OpenStack, Fabel says Canonical is on track to witness “the most commercial activity in OpenStack” ever in the coming quarter, with business coming from a variety of verticals. Clearly, Fabel says, OpenStack remains a go-to solution for enterprises of many different stripes. read more

Safe Eyes – protect your eyes from eye strain

2019-09-21 18:59:10

Many people who regularly use computers suffer from eye strain and fatigue. Looking at a monitor for a long time can strain your eyes or can make any other problems you are having with your eyes seem more apparent. There is also research to show that late-night exposure to bright lights can affect sleep quality. This can be mitigated by reducing blue-light exposure. Some monitors offer various eye care technologies including flicker-free technology, and an ultra-low blue light filter with different filter settings. But even if your display offers eye care technology and it’s well designed e.g. offering hotkeys that let you easily adjust filter settings. there’s still a good case to use a software solution as well. This is because the software typically offers more flexibility, such as the ability to automatically adjust the backlight and screen temperature based on the ambient brightness in your surroundings, or on a time schedule. There are lots of simple steps you can take to reduce eye strain and fatigue. These include adjusting the brightness, contrast settings, and text size displayed, as well as minimizing glare, and ensuring your room has proper lighting. Taking regular breaks is also very important. This is where Safe Eyes can help. It’s a clone of EyeElo, Windows proprietary software designed to protect your eyes. read more

Linux 5.4 Developments

2019-09-21 18:45:58

F2FS Linux 5.4 Changes Sent In With Case-Insensitivity, Get/Set Label Support While most of the other Linux file-systems are seeing mostly mundane changes for the Linux 5.4 feature work, the F2FS activity is fairly notable. Most notably, F2FS now has case-folding/case-insensitive support. The F2FS case-insensitive support is based upon the recent addition to the EXT4 file-system and allows for per-directory case-insensitive file/folder look-ups. On a per-directory basis (such as for Wine and other use-cases), Unicode-based case-folding can be enabled if desiring this functionality. This F2FS support for Linux 5.4 case-folding includes a port of the recent EXT4 case-folding optimization to allow for faster look-ups. Linux 5.4 Kernel Adds Driver For The Mysterious Pensando Ionic Network Hardware Little is publicly known about stealth networking startup Pensando Systems, which is founded by former Cisco executives. They've been ramping up efforts since early 2018 but to date their web-site hasn't launched nor formally introduced any products, but they now have a networking driver in the mainline Linux kernel. Linux 5.4 Prepares IBM POWER For The Ultravisor / Secure Virtual Machines The PowerPC/POWER architecture changes were sent in today for the ongoing Linux 5.4 merge window. This time around are some interesting POWER changes with work on their means of secure virtual machines. The Linux 5.4 kernel for POWER is bringing initial support for running on a system with an Ultravisor, which is IBM's approach for code running underneath a hypervisor and used for protecting guests from attacks by the hypervisor. Similarly, Linux 5.4 brings support for building a kernel to run as a Secure Virtual Machine (SVM) -- a guest running within an Ultravisor-ed environment. read more

Microsoft Distrust, Lock-in, and Openwashing

2019-09-21 11:21:30

[Old] Microsoft, there is a way to win our trust The purpose of this post is to explain why I think it's both justified and crucial to be very skeptical of these claims from Microsoft, and what Microsoft can do to allay our well-warranted doubts. And Microsoft, in keeping with the open source tradition from which it arises, I hope you take this unsolicited tunking in the way it's intended. Why not GitHub? GitHub has investors who do not care a whit for free software principles, and eventually the company will get acquired—maybe tomorrow, maybe next year—and as we all know, money changes everything. Don’t leave your project’s nerve center—its primary address, its means of contribution, its issue tracker, its website, its primary documentation, its continuous integration, everything—in a way you can’t redirect!—at the mercy of people who merely want a return on their investment, and do not care about the principles of a minority of angry nerds.

Mirrors for Speedier Downloads

2019-09-21 10:40:16

To put it briefly, PureOS provides ISO images and packages for download. Recently, we’ve seen increased traffic on our download site, and we expect that traffic to grow. We’re hoping to address increased traffic with mirrors for both package updates and downloads. We’re very happy to announce that Sonic, a highly-ranked and privacy-respecting ISP, has offered to host a mirror for PureOS. This will alleviate some of the traffic, especially for those in North America, without compromising security. The security of the packages remains guaranteed by our signatures; the mirror simply holds another, identical set of packages, signed with Purism’s key. The mirror is easy to use. For example, if you’d like to use the mirrors for downloading an image, simply use this URL: https://mirrors.sonic.net/pureos/downloads/.

Graphics: AMD, GNOME Shell on Wayland and NVIDIA Nsight Graphics

AMD Pushes Back 3rd Gen Threadripper & Ryzen 9 3950X Until November While the Ryzen 9 3950X and 3rd Gen Ryzen Threadripper processors were reportedly on track for launching in October with updates as of a few weeks ago, today AMD announced a slight delay in launching these new processors. AMD have delayed the Ryzen 9 3950X and 3rd generation Threadripper until November Today, AMD sent out a brief statement about a delay in their 16 core Ryzen 9 3950X and the 3rd generation Threadripper. [...] So if you were looking to grab either, keep an eye out in November. Will share any more news when they send it about the expected date and pricing. AMD Sends In Initial Batch Of Fixes To Linux 5.4 - Includes Dali Support While just yesterday the big DRM feature pull was sent in for Linux 5.4, AMD has also volleyed out their initial batch of fixes for this next version of the kernel. This new AMDGPU pull isn't strictly fixes but as anticipated does include the recently reported Dali APU support. Dali along with Renoir -- also newly-supported in Linux 5.4 -- are some of AMD's 2020 APUs. Dali will be targeting the lower-end of the spectrum it's expected for value mobile/embedded. From the driver code, Dali looks like a newer revved version of the current-gen Picasso APUs. Both Dali and Renoir are based on the Vega architecture. Linux Plumbers Conference 2019, part 2 Pain points and missing pieces with Wayland, or specifically GNOME Shell: GNOME Shell is slower Synergy doesn't work(?) - needs to be in the compositor With Nvidia proprietary driver, mutter and native Wayland clients get GPU acceleration but X clients don't No equivalent to ssh -X. Pipewire goes some way to the solution. The whole desktop can be remoted over RDP which can be tunnelled over SSH. No remote login protocol like XDMCP No Xvfb equivalent Various X utilities that grab hot-keys don't have equivalents for Wayland Not sure if all X's video acceleration features are implemented. Colour format conversion and hardware scaling are implemented. Pointer movement becomes sluggish after a while (maybe related to GC in GNOME Shell?) Performance, in general. GNOME Shell currently has to work as both a Wayland server and an X compositor, which limits the ability to optimise for Wayland.

Ubuntu: Video Encoder Performance, Ubuntu Touch, LZ4 Compression

2019-09-21 09:38:55

Clear Linux vs. Ubuntu 19.10 Video Encoder Performance On The Core i9 9900K Often when doing cross-distribution benchmarks, readers often comment on the performance of Clear Linux particularly for video encoding use-cases as surprisingly different from other distributions. Some argue that it's just over the default CPU frequency scaling governor or compiler flag defaults, so here is a look at that with Ubuntu 19.10 daily benchmarked against Clear Linux. On the same Core i9 9900K system I recently ran some benchmarks looking at Clear Linux vs. Ubuntu 19.10 and then Ubuntu 19.10 with various common tunables to make it more akin to Clear Linux. Ubuntu 19.10 was used due to its recent software components being at similar versions to Intel's rolling-release distribution. Serge Hallyn: First experience with Ubuntu Touch For the past few weeks I’ve been using a nexus 4 running ubuntu touch as, mostly, my daily driver. I’ve enjoyed it quite a bit. In part that’s just the awesome size of the nexus 4. In part, it’s the ubuntu touch interface itself. If you haven’t tried it, you really should.

The Vivaldi 2.8 Release (Proprietary)

2019-09-21 09:36:22

Vivaldi 2.8 Released with Unified Sync Support for Desktop and Android Vivaldi Technologies released today the Vivaldi 2.8 web browser for desktop platforms, including GNU/Linux, macOS, and Windows, an incremental update that adds significant improvements. With Vivaldi 2.8, Vivaldi Technologies continues to give desktop users full control over their browsing experience by adding various improvements across the board, starting with Vivaldi Sync, which now lets you sync bookmarks, passwords, history, notes, and autofill information across desktop and mobile. That's right, starting with Vivaldi 2.8, all your browsing data will be automatically synchronized between your installations of Vivaldi on desktop platforms, such as Linux, Mac, or Windows, and your mobile device where Vivaldi for Android is installed if you use Vivaldi Sync. New Version Vivaldi Web Browser Has Been Released, Install in Ubuntu/Linux Vivaldi is the new web browser compare to other famous browsers, the initial release of Vivaldi was in January, 2015. It has improved a lot and evolved since the first release. Basically it is based on the open-source frameworks of Chromium, Blink and Google's V8 JavaScript engine and has a lot of great feature which I will table later. It is known to be the most customizable browser for power users, debuts features that make browsing more personal than ever before. Do we really need another browser? Since we already have a lot of them such as mostly used Firefox, Chrome, Opera and so on. The former CEO of Opera Software Jon Von Tetzchner didn't liked the direction of Opera Web Browser and said "Sadly, it is no longer serving its community of users and contributors - who helped build the browser in the first place." Then created a web browser which has to be fast, rich feature, highly flexible and puts the user first, so Vivaldi was born. Vivaldi 2.8: Inspires new desktop and mobile experiences Today we are launching a new upgrade to our desktop version – Vivaldi 2.8. We’re always focused on giving you complete control over your desktop experience, while also making sure to protect your privacy and security online. Vivaldi on the desktop has been our foundation. And now – our inspiration. It continuously pushes us forward to deliver a browser that is made for you.

Wisconsin Broadcasters Clinic Preview: Raspberry Pi

2019-09-20 22:37:18

The Raspberry Pi is a single board SOC (system on a chip) computer that is about the size of a deck of cards. It runs a ARMCore version of Debian Linux in a standard configuration but can also run Ubuntu Linux, several other more obscure OSes, and Windows 10 IOT (If you like the Microsoft [non]security model). The basic Raspberry Pi model lists at $35 US so it is a very cost effective solution for those broadcast applications that would normally require a full blown PC to just loaf along and do one thing. I have implemented several applications for the Raspberry Pi for our studios and transmitters for Cumulus Chicago. We will be showing, hands-on, several of these applications at the “Nuts and Bolts” session of the Wisconsin Broadcasters fall show. My first application was porting Anthony Eden’s Livewire Simple Delegation Switcher to the Pi. At that point it only ran on Windows in a windowed configuration. I needed a border-less configuration with large buttons to use as a monitor routing panel to select which audio went to overhead speakers in Sales, Promotions, and common areas. Since the code is open source, I modified it to fit my needs. Since that time, Anthony has posted Raspberry Pi configuration instructions on his GIT repository web site. read more

AMD EPYC 7642 Benchmarks: The Rome 48 Core CPU That Easily Takes On Intel's Xeon Platinum 8280

2019-09-20 22:35:14

Since the AMD EPYC 7002 series "Rome" launch at the beginning of August, it's been known how AMD's top-end (aside from the newly-announced EPYC 7H12) EPYC 7742 easily outperforms the Intel Xeon Platinum 8280 in most real-world benchmarks. The EPYC 7742 not only outperforms the Xeon Platinum 8280 in raw performance but also at a significantly lower cost and it gets even better with the EPYC 7642. We have been testing the EPYC 7642 48-core processors and even there the performance is generally ahead of a Xeon Platinum 8280 while being about half the cost of that flagship non-AP Intel Xeon Scalable Cascadelake processor. Complementing our recent EPYC 7302 and EPYC 7402 benchmarks, today we are focused on the EPYC 7642 as the Rome 48-core / 96-thread processor. This 48 core processor has a 2.3GHz base clock and 3.3GHz boost clock while having 256MB of L3 cache, eight DDR4-3200 memory channels, 128 PCIe 4.0 lanes, and other features in common with the EPYC 7742 and other Rome processors. The EPYC 7642 carries a 50MHz base clock speed advantage over the 64 core EPYC 7742 but a 100MHz lower boost clock speed as the principal differences aside from the core/thread count. Both of these CPUs carry a 225 Watt TDP. read more

Top Open Source Video Players for Linux

2019-09-20 22:23:40

You can watch Hulu, Prime Video and/or Netflix on Linux. You can also download videos from YouTube and watch them later or if you are in a country where you cannot get Netflix and other streaming services, you may have to rely on torrent services like Popcorn Time in Linux. Watching movies/TV series or other video contents on computers is not an ‘ancient tradition’ yet. Usually, you go with the default video player that comes baked in with your Linux distribution (that could be anything). You won’t have an issue utilizing the default player – however, if you specifically want more open-source video player choices (or alternatives to the default one), you should keep reading. read more

The Humble Monthly has expanded to add BATTLETECH expansions plus Sonic Mania

2019-09-20 20:17:34

Tags: Humble Store, Game BundleWas BATTLETECH as the only early unlock for the current Humble Monthly not enough for you? Good news, you can now play more right away as they've expanded it. Just added today alongside the full game of BATTLETECH are two expansions: Flashpoint and the Shadow Hawk Pack. That should keep you going until you decide if you want to pick up Urban Warfare (not included) and the upcoming Heavy Metal expansion. BATTLETECH supports Linux and the expansions do work fine in my own testing. The other brand new early reveal (and one you can play right now) is Sonic Mania. While it doesn't have Linux support, it does work in Steam Play and it's a good bit of fun. I have some seriously fond memories of playing Sonic when I was much younger on the Sega Mega Drive while I was in hospital but that's a story for another time… You can pick up the Humble Monthly here if interested.Article from GamingOnLinux.com

AMD have delayed the Ryzen 9 3950X and 3rd generation Threadripper until November

2019-09-20 20:05:48

Tags: AMD, HardwareToday, AMD sent out a brief statement about a delay in their 16 core Ryzen 9 3950X and the 3rd generation Threadripper. Here's what AMD said in full: We are focusing on meeting the strong demand for our 3rd generation AMD Ryzen processors in the market and now plan to launch both the AMD Ryzen 9 3950X and initial members of the 3rd Gen AMD Ryzen Threadripper processor family in volume this November. We are confident that when enthusiasts get their hands on the world's first 16-core mainstream desktop processor and our next-generation of high-end desktop processors, the wait will be well worth it. Quite a bit of a delay, considering they gave the Ryzen 9 3950X an expected release date of this month when the 3rd Gen Ryzen desktop processors originally released. Still, it's obviously good business sense to ensure you can actually keep up with the current consumer demand before pushing out even more products. The Ryzen 9 3950X is looking to be an absolute beast with 16 cores and 32 threads but that's going to be completely trumped by the 3rd generation Threadripper with a massive 24 cores, which AMD teased in a fresh PR image: So if you were looking to grab either, keep an eye out in November. Will share any more news when they send it about the expected date and pricing.Article from GamingOnLinux.com

Games: Valve, Hot Lava, Drawn Down Abyss and More

2019-09-20 20:05:47

A French court has ruled that Valve should allow people to re-sell their digital games Valve and game developers have a bit of a fight on their hands here, with a French court ruling that Valve should allow users to re-sell their digital games. Reported by the French website Next Inpact, the French consumers group UFC Que Choisir had a victory against Valve as French courts have ruled against them on the topic of reselling digital content. From what I've read and tried to understand, the courts have basically said that when you buy something on Steam it is indeed a proper purchase and not a subscription. Valve has been ordered to pay damages at €20K plus €10K to cover some costs. On top of that, they will also have to publish the judgement on Steam's home page (presumably only for users in France) and for it to remain visible for three months. If they don't, they will get a fine for each day of €3K. To Valve though, that's likely pocket change. The bigger issue though, is how other countries inside and outside the EU could follow it. Hot Lava from Klei Entertainment is in the works for Linux Just recently Klei Entertainment (Don't Starve, Oxygen Not Included) released their amusing parkour game Hot Lava and it's not only planned for Linux they're actually working on it. It looks and sounds like a ridiculous amount of fun too, a 3D platformer inspired by the classic kids game. I'm sure everyone has played it at some point in their lives. Get a bunch of pillows and cushions, throw them around and don't touch the floor! Klei managed to turn that into a pretty good looking game PC game. Post-apocalyptic road-trip strategy game Overland has officially released, some thoughts After a few years in Early Access on itch.io, Finji have officially released their post-apocalyptic road-trip strategy game Overland. Dota 2 is going through multiple big ban waves and some matchmaking changes Valve are trying to clean up the Dota 2 community and make matchmaking better, with some big changes being done. First up, let's talk a little about the recent major ban waves. Valve said they have removed players from Dota 2 with "exceptionally low behavior scores" and they will continue to do so regularly, which is good and very much needed to keep the online community healthy. They have also done a second ban wave for anyone who has been "detected of violating the Steam Service Agreement that prevents the purchase or sale of Steam accounts"—ouch. A third wave happened, to remove players who've been using "exploits to gain an advantage over other players" and they will be adjusting how they detect such things over the coming weeks. Not only that, bans will also now block the phone number associated with the account permanently, so people will have to setup a new phone making it more difficult for nuisance players to come right back. Linking directly with that, Valve said they closed a hole that allowed "a large number of users to play ranked without a unique phone number attached" to help against smurf accounts. On top of all that again, to gain access to Ranked play you need to have 100 hours logged in the game. Drawn Down Abyss takes an action platformer and adds in card deck-building for abilities Platformers are probably the most common type of game available on any platform and yet, some developers are still able to make them seem a little unique. Drawn Down Abyss is one such game, a pixel art action-focused platformer. The difference here, is they're pulling in the card-based deck-building for your abilities. Deck-building is massively popular right now, it's one of those things that one or two games did really well and now more want to try it. I'm happy about this, I'm a fan of collecting cards and using them to battle with so trying it out with an action platformer has piqued my interest. Top-down racer Bloody Rally Show looks great in the new trailer One racing game I am genuinely excited about is Bloody Rally Show, a top-down racer that looks genuinely good and it has a fresh trailer up to show off recent development progress. It will fully supported Linux too, as I tested out previously. One of the reasons I'm excited about this, is that it firmly reminds me of some classic early racers from the Amiga only with everything turned up a notch or two. Not only that, something of a rarity in racing games is that it will have a fully featured campaign story mode with cut-scenes and all. This campaign mode can even be played in local co-op. read more

This allows you to compete in the Time Attack mode for the fastest lap times against a ghost car of someone above you in the leader-board. If you're number one, you will race against your own ghost. When introducing Asynchronous Multiplayer, the developer said "online multiplayer is not available (yet)" so that might even be a little tease that it's coming later too. Some small and helpful tweaks have been included recently too, like the mini-map being customizable in both size and position. Game Hero Interactive have also been keeping up with Unity game engine updates, so it should run very nicely at release. Feature Highlight: Satisfying arcade-style car physics (handling, drifting, speed) Infinite amount of randomly generated Race Tracks Possibility to share your custom built cars and tracks on Steam Workshop for others to enjoy Racer XP and level-up Car tuning and upgrades Custom paint jobs and racer avatars Split Screen Local multiplayer for up to 4 players Configuration setting to turn off blood (for family friendly split screen racing sessions) Races with 100 opponents! After playing it for quite a few hours now myself, I've begun to get a little attached to it when needing to burn off a little steam myself. I seem to spend far too much time customizing my paint job too, there's so many variations possible. Just look at this sweet little ride: The new ghost car feature is also awesome, really makes the game a whole lot more fun. I also seem to find it impossible to beat my own times once I set them. If you like racing games, this is one you need to keep an eye on. You can wishlist and follow on Steam ready for release next year.Article from GamingOnLinux.com

Drawn Down Abyss takes an action platformer and adds in card deck-building for abilities

2019-09-20 12:06:09

Tags: Deck-builder, Action, Platformer, Indie Game, Steam, Upcoming, Pixel GraphicsPlatformers are probably the most common type of game available on any platform and yet, some developers are still able to make them seem a little unique. Drawn Down Abyss is one such game, a pixel art action-focused platformer. The difference here, is they're pulling in the card-based deck-building for your abilities.

Dota 2 is going through multiple big ban waves and some matchmaking changes

2019-09-20 11:51:09

Tags: MOBA, Valve, Steam, Free Game, UpdateValve are trying to clean up the Dota 2 community and make matchmaking better, with some big changes being done. First up, let's talk a little about the recent major ban waves. Valve said they have removed players from Dota 2 with "exceptionally low behavior scores" and they will continue to do so regularly, which is good and very much needed to keep the online community healthy. They have also done a second ban wave for anyone who has been "detected of violating the Steam Service Agreement that prevents the purchase or sale of Steam accounts"—ouch. A third wave happened, to remove players who've been using "exploits to gain an advantage over other players" and they will be adjusting how they detect such things over the coming weeks. Not only that, bans will also now block the phone number associated with the account permanently, so people will have to setup a new phone making it more difficult for nuisance players to come right back. Linking directly with that, Valve said they closed a hole that allowed "a large number of users to play ranked without a unique phone number attached" to help against smurf accounts. On top of all that again, to gain access to Ranked play you need to have 100 hours logged in the game. Amusingly the bans are listed as being until January, 2038. They are permanent though, it's likely just the way Valve are storing the dates has the "Year 2038 problem". They probably need to adjust their database to support a different time storage method. As for matchmaking, they continue to tweak the new Role systems in place. Part of that is ensuring that the games are actually balanced. They're going to be putting a larger emphasis on making sure that the roles are more symmetric based on player ranking rather than just spreading the rank across each time and making it match up. There's a new reporting option included too, as some players were not playing properly as the Role they queued up for so Valve said they're going to be a little more "aggressive in punishing players who abuse the system". There's more to it, see the full blog post here.Article from GamingOnLinux.com

Post-apocalyptic road-trip strategy game Overland has officially released, some thoughts

2019-09-20 11:23:57

Tags: Review, New Release, Strategy, Survival, Indie Game, GOG, Steam, Itch.io, DRM-FreeAfter a few years in Early Access on itch.io, Finji have officially released their post-apocalyptic road-trip strategy game Overland. Note: Personal copy. Take care of a group of travelers on a post-apocalyptic road-trip across the United States in this turn-based survival game. Fight scary creatures, rescue stranded survivors, and scavenge for supplies like fuel, first aid kits, and weapons. Decide where to go next, whether it's upgrading this wrecked car, or rescuing that dog. Just remember, there are consequences for every action. Get ready for close calls, dramatic escapes, hard choices, arguing about whether or not that dog gets rescued, and the end of the world. The first thing you really notice when playing Overland is the incredibly moody atmosphere. It's not a happy game, it doesn't pretend to be or try to cover it up either. This is the end of the world, you're trying to survive and it is a true struggle. That and the small contained levels where you're looking at just a slice of a location. Even though the levels aren't big, there's a huge amount going on under the surface. While Overland has the familiar turn-based feel and style that games like XCOM made popular, it still plays nothing like them. You don't run for cover and there's no special abilities or gaining experience. The only one who changes is—you, by learning how to do deal with these creatures and how to best use the seriously limited resources you have. Since the maps are small, you don't get a chance to actually do much. Each character has a very limited set of action points, so you really have to use them wisely. Everything is a toss-up between checking that dumpster out and finding some fuel or perhaps a shiny new weapon or escaping with all your limbs intact. Combat as well, is something that you're only going to be doing as an absolute last resort. In a way, you never truly feel like you're getting anywhere. I feel that's part of the point though, to keep you on your toes always on the look out for something useful. How am I supposed to find anything in that fog? Note: If you use the in-game screenshot tool, it saves the shots to this location: ".config/unity3d/Finji/Overland/Screenshots". The real problem is, the little (and some big) beasts are attracted by sound. Give one a good wack on the head? Prepare for the sound to draw more of them to the surface. Thankfully, it's not just you that has a limited amount of points to move with. Enemies coming up to the surface doesn't happen instantly, they have to first poke their head up and then crawl up before they can get a turn at making you into dinner. Since this is the post-apocalypse, the strange creatures aren't all you're dealing with. During one run, everything was going incredibly smoothly. I had rescued someone, found a bigger car and managed to attach some top-notch floodlights onto the top and after pimping my ride I felt like nothing could stop me. However, my companion got stuck between two nasties and she died shortly after that. I escaped and went looking for fuel, only to encounter another survivor who decided to pour out a bunch of fuel to attract a creature and when I went to grab a can he left, he stole my fucking car! I wasn't exactly left with much after the carjacking…nothing actually. Once a run starts going bad, it can get pretty damn tense. You will either be the luckiest person around and find what you need or you're totally screwed. Naturally, the latter is what I usually end up as. After my car was stolen this was what I had to deal with after a short walk to find another car: I died pretty soon after entering that area. Thankfully, not all is lost at times. If you do manage to complete an area, when starting a new game you do have the option of beginning your journey there. Another part of the difficulty in Overland is a design choice of explaining a grand total of nothing. It's a survival strategy game that forces you to think and learn on the go, for better or worse. Some of you may enjoy that, at times I did but there's other times where I feel like I wished I knew more about the world, about the characters, about what items I might be able to find. A little personal gripe with Overland is that they should have made the interface between driving and walking easier, it can be a little confusing sometimes if you've selected a character or the car to drive. An easier way to quickly switch would have been nice. Small issue though. My bigger gripe is how it feels like it hasn't really progress far from the early builds I played over the last few years. I don't know if that's because it doesn't explain anything and so everything feels hidden or if it just really hasn't actually expanded all that much. Features/Gameplay Highlights: Always keep fuel in the tank. Stay away from the creatures. Be careful. Be quiet. Loud sounds attract trouble, and there's no way you can fight them all. Grab as much gas as you can, rescue that trapped stranger, and get back in the car before it's too late. Travel West, through grasslands, over mountains, across deserts, and to even stranger places. Every level, roadmap, and character is randomly generated, so each trip is new. Equip dozens of items, including medkits, shields, axes, potted plants, scavenged armor, and luggage racks. A completely new end of the world from Finji (Canabalt, Night in the Woods). It can be thought of like a slower turn-based, more focused and intimate Death Road to Canada. The basic ideas are the same but the gameplay is very different. Overland can be quite punishing, so on that note it's certainly not going to be for everyone. I personally purchased this one all the way back in 2016, so I've been waiting for the full release for what feels like forever. Overall it's incredibly stylish, very challenging and worth a purchase if you do enjoy such games usually. I'm happily going to jump in and play some more soon. You can pick up Overland from GOG, itch.io and Steam.Article from GamingOnLinux.com

Hot Lava from Klei Entertainment is in the works for Linux

When Diverse Network ASICs Meet A Unifying Operating System

2019-09-20 04:02:12

And it has also been a decade since switch upstart Arista Networks launched its Extensible Operating System, or EOS, which is derived from Linux. [...] The cross-platform nature of ArcOS, coupled with its ability to run in any function on the network, could turn out to be the key differentiator. A lot of these other NOSes were point solutions that could only be deployed in certain parts of the network, and that just creates animosity with the incumbent vendors that dominate the rest of the networking stack. Given the mission-critical nature of networking in the modern datacenter, it costs a great deal to qualify a new network operating system, and it can take a lot of time. If ArcOS can run across more platforms, qualify faster, and do more jobs in the network, then, says Garg, it has a good chance of shaking up switching and routing. “That totally changes the business conversation and the TCO advantages that we can bring to a customer across the entirety of their network.” read more

Server: Kubernetes/OpenShift, OpenStack, and Red Hat's Ansible

2019-09-20 03:51:32

9 steps to awesome with Kubernetes/OpenShift presented by Burr Sutter Burr Sutter gave a terrific talk in India in July, where he laid out the terms, systems and processes needed to setup Kubernetes for developers. This is an introductory presentation, which may be useful for your larger community of Kubernetes users once you’ve already setup User Provisioned Infrastructure (UPI) in Red Hat OpenShift for them, though it does go into the deeper details of actually running the a cluster. To follow along, Burr created an accompanying GitHub repository, so you too can learn how to setup an awesome Kubernetes cluster in just 9 steps. Weaveworks Named a Top Kubernetes Contributor But anyone who knows the history of Weaveworks might not be too surprised by this. Weaveworks has been a major champion of Kubernetes since the very beginning. It might not be too much of a coincidence that Weaveworks was incorporated only a few weeks after Kubernetes was open sourced, five years ago. In addition to this, the very first elected chair of the CNCF’s Technical Oversight Committee, responsible for technical leadership to the Cloud Native Foundation was also headed up by our CEO, Alexis Richardson(@monadic) (soon to be replaced by the awesome Liz Rice (@lizrice) of Aqua Security). Improving trust in the cloud with OpenStack and AMD SEV This post contains an exciting announcement, but first I need to provide some context! Ever heard that joke “the cloud is just someone else’s computer”? Of course it’s a gross over-simplification, but there’s more than a grain of truth in it. And that raises the question: if your applications are running in someone else’s data-centre, how can you trust that they’re not being snooped upon, or worse, invasively tampered with? Red Hat OpenStack Platform 15 Enhances Infrastructure Security and Cloud-Native Integration Across the Open Hybrid Cloud Red Hat, Inc., the world's leading provider of open source solutions, today announced the general availability of Red Hat OpenStack Platform 15, the latest version of its highly scalable and agile cloud Infrastructure-as-a-Service (IaaS) solution. Based on the OpenStack community’s "Stein" release, Red Hat OpenStack Platform 15 adds performance and cloud security enhancements and expands the platform’s ecosystem of supported hardware, helping IT organizations to more quickly and more securely support demanding production workloads. Given the role of Linux as the foundation for hybrid cloud, customers can also benefit from a more secure, flexible and intelligent Linux operating system underpinning their private cloud deployments with Red Hat Enterprise Linux 8. Red Hat Ansible Automation Accelerates Past Major Adoption Milestone, Now Manages More Than Four Million Customer Systems Worldwide Red Hat, Inc., the world's leading provider of open source solutions, today announced that more than four million customer systems worldwide are now automated by Red Hat Ansible Automation. Customers, including Energy Market Company, Microsoft, Reserve Bank of New Zealand and Surescripts all use Red Hat Ansible Automation to automate and orchestrate their IT operations, helping to expand automation across IT stacks. According to a blog post by Chris Gardner with Forrester Research, who was the author of The Forrester Wave™: Infrastructure Automation Platforms, Q3 2019, "Infrastructure automation isn’t just on-premises or the cloud. It’s at the edge and everywhere in between."1 Since its launch in 2013, Red Hat Ansible Automation has provided a single tool to help organizations automate across IT operations and development, including infrastructure, networks, cloud, security and beyond. read more

uwsgi weirdness with --http Instead of upgrading everything on my server, I'm just starting from scratch. From Ubuntu 16.04 to Ubuntu 19.04 and I also upgraded everything else in sight. One of them was uwsgi. I copied various user config files but for uwsgi things didn't very well. On the old server I had uwsgi version 2.0.12-debian and on the new one 2.0.18-debian.

Wingware Blog: Viewing Arrays and Data Frames in Wing Pro 7 Wing Pro 7 introduced an array and data frame viewer that can be used to inspect data objects in the debugger. Values are transferred to the IDE according to what portion of the data is visible on the screen, so working with large data sets won't slow down the IDE. The array viewer works with Pandas, numpy, sqlite3, xarray, Python's builtin lists, tuples, and dicts, and other classes that emulate lists, tuples, or dicts. Solving Sequence Problems with LSTM in Keras: Part 2 This is the second and final part of the two-part series of articles on solving sequence problems with LSTMs. In the part 1 of the series, I explained how to solve one-to-one and many-to-one sequence problems using LSTM. In this part, you will see how to solve one-to-many and many-to-many sequence problems via LSTM in Keras. Image captioning is a classic example of one-to-many sequence problems where you have a single image as input and you have to predict the image description in the form of a word sequence. Similarly, stock market prediction for the next X days, where input is the stock price of the previous Y days, is a classic example of many-to-many sequence problems. In this article you will see very basic examples of one-to-many and many-to-many problems. However, the concepts learned in this article will lay the foundation for solving advanced sequence problems, such as stock price prediction and automated image captioning that we will see in the upcoming articles. Voronoi Mandalas I started with Carlos Focil's mandalapy code, modifying the parameters until I had a design I liked. I decided to make the Voronoi diagram show both points and vertices, and I gave it an equal aspect ratio. Carlos' mandalapy code is a port of Antonio Sánchez Chinchón's inspiring work drawing mandalas with R, using the deldir library to plot Voronoi tesselations. Python Code Kata: Fizzbuzz A code kata is a fun way for computer programmers to practice coding. They are also used a lot for learning how to implement Test Driven Development (TDD) when writing code. One of the popular programming katas is called FizzBuzz. This is also a popular interview question for computer programmers. why python is the best-suited programming language machine learning Machine Learning is the hottest trend in modern times. According to Forbes, Machine learning patents grew at a 34% rate between 2013 and 2017 and this is only set to increase in the future. And Python is the primary programming language used for much of the research and development in Machine Learning. So much so that Python is the top programming language for Machine Learning according to Github. Python is currently the most popular programming language for research and development in Machine Learning. But you don’t need to take my word for it! According to Google Trends, the interest in Python for Machine Learning has spiked to an all-new high with other ML languages such as R, Java, Scala, Julia, etc. lagging far behind. Node.js now available in Haiku As some have already known for a long time, many platforms have had support for writing software in JavaScript or TypeScript with the help of the Node.js runtime and over the years, much of the software written by developers these days have gradually been written in either of those languages. However, Haiku has lacked a Node.js port for quite sometime and it wasn’t possible to run or develop JavaScript based software or libraries that depended on the Node.js runtime. Now I can say that Node.js is available for Haiku and can be downloaded from HaikuDepot on 64 bit (32 bit support is being worked on). The version which is currently available is 12.3.1 and is already being updated to the latest version at the time of this writing to 12.10.0 and support for the upcoming LTS version is also coming to HaikuPorts. Several patches have been upstreamed by members of the HaikuPorts team to projects such as libuv (cross-platform async I/O library), GN, etc and we hope to upstream to larger projects like V8 (Google’s JavaScript engine used in Chromium and QtWebEngine) and the Node.js project, which will ease the bringup of a future Node LTS release for Haiku. Node.js Brought To BeOS-Inspired Haiku Open-Source OS Haiku as the open-source operating system that still maintains BeOS compatibility continues tacking on modern features and support for software well past the days of BeOS. The newest major piece of software working on BeOS is Node.js, including support for its NPM package manager. LLVM 9.0 Released With Ability To Build The Linux x86_64 Kernel, Experimental OpenCL C++ It's coming almost one month behind schedule, but LLVM 9.0 is out today along with the Clang 9.0 C/C++ compiler and associated sub-projects for this open-source compiler infrastructure. LLVM 9.0 is an exciting release with bringing the ability to build the mainline Linux x86_64 kernel using LLVM/Clang 9.0 now that "asm goto" support was finally added. The AArch64 support was in better standing previously but now at long last the mainline Clang 9.0 compiler can build the current Linux kernel releases with not needing any extra patches on either side, just point the kernel build CC to Clang. read more

Linux 5.4 Development, PRs, Merges

2019-09-20 03:29:32

BLK-IOCOST Merged For Linux 5.4 To Better Account For Cost Of I/O Workloads BLK-IOCOST is a new I/O controller by veteran kernel developer Tejun Heo that is a work-conserving proportional controller. He goes over blk-iocost in great detail in one of the earlier patch series, "It currently has a simple linear cost model builtin where each IO is classified as sequential or random and given a base cost accordingly and additional size-proportional cost is added on top. Each IO is given a cost based on the model and the controller issues IOs for each cgroup according to their hierarchical weight. By default, the controller adapts its overall IO rate so that it doesn't build up buffer bloat in the request_queue layer, which guarantees that the controller doesn't lose significant amount of total work...The controller provides extra QoS control knobs which allow tightening control feedback loop as necessary." See that aforelinked article for more details and results. Btrfs & XFS File-Systems See More Fixes With Linux 5.4 The mature XFS and Btrfs file-systems continue seeing more fixes and cleaning with the now in-development Linux 5.4 kernel. On the Btrfs front the Linux 5.4 changes are summed up as "work on code refactoring, sanity checks and space handling. There are some less user visible changes, nothing that would particularly stand out." The Btrfs changes include deprecating a few items as well as improving the exposure of debugging information via sysfs. See the pull request for all the Btrfs file-system fixes and changes this round.

We release regularly. Here are the release notes from version 203. Attention: Fedora Yahoo Email Users Going from a blast of the past we are currently going through one of the Yahoo is not allowing many emails with either fedoraproject.org OR from our mail routers. It would seem that the way to get yahoo to blacklist a domain is to get subscribed to mailing lists and then report the lists as SPAM. Enough accounts (or maybe if one person does it enough times).. yahoo will helpfully blacklist the domain completely. [It then is usually a multi-month process of people explaining that no Fedora is not a spam site, hasn't been taken over by a spam site, or a bunch of other things which do happen so any mail admin is going to be wary on.] read more
