  • Rivals Red Hat, Mirantis Announce New OpenStack Partnerships

    The cloud rivals both announce new telco alliances as competition in the cloud market heats up.
    Red Hat and Mirantis both announced large agreements this week that bring their respective OpenStack technologies to carrier partners. The news comes ahead of the OpenStack Summit that kicks off in Barcelona, Spain, on Oct. 24.

    Red Hat announced on Oct. 19 that it has a new OpenStack partnership with telco provider Ericsson.

    "Ericsson and Red Hat recognize that we share a common belief in using open source to transform the telecommunications industry, and we are collaborating to bring more open solutions, from OpenStack-based clouds to software-defined networking and infrastructure, to customers," Radhesh Balakrishnan, general manager of OpenStack at Red Hat, told eWEEK.

This presentation was given at the GNOME 3.22 release party, organized by the Beijing GNOME User Group.

  • The who in the where?

    The job is like many other roles called “Community Manager” or “Community Lead.” That means there is a focus on metrics and experiences. One role is to try ensure smooth forward movement of the project towards its goals. Another role is to serve as a source of information and motivation. Another role is as a liaison between the project and significant downstream and sponsoring organizations.

    In Fedora, this means I help the Fedora Project Leader. I try to be the yen to his yang, the zig to his zag, or the right hand to his right elbow. In all seriousness, it means that I work on a lot of the non-engineering focused areas of the Fedora Project. While Matthew has responsibility for the project as a whole I try to think about users and contributors and be mechanics of keeping the project running smoothly.

    “This is awesome!”, this was my first reaction when I boarded my first flight to Delhi. I was having trouble in finding a proper accommodation Kushal, Sayan and Chandan helped me a lot in that part, I finally got honour of bunking with Sayan , Subho and Rtnpro which I will never forget. So, I landed and directly went to JNU convention center. I met the whole Red Hat intern gang . It was fun to meet them all. I had proposed Pagure for Dev Sprint and I pulled in Vivek to do the same.

    The dev sprint started and there was no sign of Vivek or Saptak, Saptak is FOSSASIA contributor and Vivek contributes to Pagure with me. Finally it was my turn to talk about Pagure on stage , it was beautiful the experience and the energy. We got a lot of young and new contributors and we tried to guide them and make them send at least one PR. One of them was lucky enough to actually make a PR and it got readily merged.

  • Hack This: An Overdue Python Primer

    In writing the most recent Hack This ("Scrape the Web with Beautiful Soup") I again found myself trapped between the competing causes of blog-brevity and making sure everything is totally clear for non-programmers. It's a tough spot! Recapping every little Python (the default language of Hack This) concept is tiring for everyone, but what's the point in the first place if no one can follow what's going on?

    This post is then intended then as a sort of in-between edition of Hack This, covering a handful of Python features that are going to recur in pretty much every programming tutorial that we do under the Hack This name. A nice thing about Python is that it makes many things much clearer than is possible in almost any other language.

  • Why I won’t be attending Systems We Love

    Here’s one way to put it: to me, Bryan Cantrill is the opposite of another person I admire in operating systems (whom I will leave unnamed). This person makes me feel excited and welcome and safe to talk about and explore operating systems. I’ve never seen them shame or insult or put down anyone. They enthusiastically and openly talk about learning new systems concepts, even when other people think they should already know them. By doing this, they show others that it’s safe to admit that they don’t know something, which is the first step to learning new things. They are helping create the kind of culture I want in systems programming – the kind of culture promoted by Papers We Love, which Bryan cites as the inspiration for Systems We Love.

    By contrast, when I’m talking to Bryan I feel afraid, cautious, and fearful. Over the years I worked with Bryan, I watched him shame and insult hundreds of people, in public and in private, over email and in person, in papers and talks. Bryan is no Linus Torvalds – Bryan’s insults are usually subtle, insinuating, and beautifully phrased, whereas Linus’ insults tend towards the crude and direct. Even as you are blushing in shame from what Bryan just said about you, you are also admiring his vocabulary, cadence, and command of classical allusion. When I talked to Bryan about any topic, I felt like I was engaging in combat with a much stronger foe who only wanted to win, not help me learn. I always had the nagging fear that I probably wouldn’t even know how cleverly he had insulted me until hours later. I’m sure other people had more positive experiences with Bryan, but my experience matches that of many others. In summary, Bryan is supporting the status quo of the existing culture of systems programming, which is a culture of combat, humiliation, and domination.


    He gaily recounts the time he gave a highly critical keynote speech at USENIX, bashfully links to a video praising him at a Papers We Love event, elegantly puts down most of the existing operating systems research community, and does it all while using the words “ancillary,” “verve,” and “quadrennial.” Once you know the underlying structure – a layer cake of vituperation and braggadocio, frosted with eloquence – you can see the same pattern in most of his writing and talks.

The basics of open source quality assurance

Filed under

Open source depends on a sustainable community to develop code rapidly, debug code effectively, and build out new features. Because community involvement is voluntary, people's skills, levels of involvement, and time commitments can vary. Given the variable nature of these factors, along with the fact that open source often relies on a philosophy of "release early, release often," quality assurance can be become challenging.

  • Puppet Rolls Out New Docker Image Builds

    Folks who are focused on container technology and virtual machines as they are implemented today might want to give a hat tip to some of the early technologies and platforms that arrived in the same arena. Among those, Puppet, which was built on the legacy of the venerable Cfengine system, was an early platform that helped automate lots of virtual machine implementations. We covered it in depth all the way back in 2008.

    Earlier this year, Puppet Labs rebranded as simply Puppet, and also named its first president and COO, Sanjay Mirchandani, who came to the company from VMware, where he was a senior vice-president. Now, at PuppetConf, the company has announced the availability of Puppet Docker Image Build, which "automates the container build process to help organizations as they define, build and deploy containers into production environments." This new set of capabilities adds to existing Puppet functionality for installing and managing container infrastructure, including Docker, Kubernetes and Mesos, among others.

  • Five Cool Alternative Open Source Linux Shells

    We are going to look at some of the available Linux shells out there that users have access to free of charge since they are open source, they come in a number of different licenses and this mainly depends on the software creator but in essence one doesn’t have to pay to use the system; so that a major plus in whichever way we look at it.
    We find that there are different kinds of users when it comes to Linux, the ones who tread carefully preferring to stick to tried and tested software, the other kinds are the ones who dive into the deep end of cutting edge software; head first.

  • The Open Source Way

    "Open source", in the world of IT, is program code that is meant for collaboration and open contribution. Intended to be modified and shared, because by design and spirit, it is meant for the public at large.

    It’s been said that “"open source" intimates a broader set of values—what we call "the open source way." Open source projects, products, or initiatives embrace and celebrate principles of open exchange, collaborative participation, rapid prototyping, transparency, meritocracy, and community-oriented development.” So it is a natural conclusion that in this age of open and transparent government, that the government IT manager or technician would be one of the first to want to embrace this new role of collaborative team member within a larger community.

  • Free tool protects PCs from master boot record attacks [Ed: UEFI has repeatedly been found to be both a detriment to security and enabler of Microsoft lock-in]

    Cisco's Talos team has developed an open-source tool that can protect the master boot record of Windows computers from modification by ransomware and other malicious attacks.

    The tool, called MBRFilter, functions as a signed system driver and puts the disk's sector 0 into a read-only state. It is available for both 32-bit and 64-bit Windows versions and its source code has been published on GitHub.

    The master boot record (MBR) consists of executable code that's stored in the first sector (sector 0) of a hard disk drive and launches the operating system's boot loader. The MBR also contains information about the disk's partitions and their file systems.

    Since the MBR code is executed before the OS itself, it can be abused by malware programs to increase their persistence and gain a head start before antivirus programs. Malware programs that infect the MBR to hide from antivirus programs have historically been known as bootkits -- boot-level rootkits.

    Microsoft attempted to solve the bootkit problem by implementing cryptographic verification of the bootloader in Windows 8 and later. This feature is known as Secure Boot and is based on the Unified Extensible Firmware Interface (UEFI) -- the modern BIOS.

  • DDOS Attack On Internet Infrastructure

    I hope somebody's paying attention. There's been another big DDOS attack, this time against the infrastructure of the Internet. It began at 7:10 a.m. EDT today against Dyn, a major DNS host, and was brought under control at 9:36 a.m. According to Gizmodo, which was the first to report the story, at least 40 sites were made unreachable to users on the US East Coast. Many of the sites affected are among the most trafficed on the web, and included CNN, Twitter, PayPal, Pinterest and Reddit to name a few. The developer community was also touched, as GitHub was also made unreachable.

    This event comes on the heels of a record breaking 620 Gbps DDOS attack about a month ago that brought down security expert Brian Krebs' website, KrebsonSecurity. In that attack, Krebs determined the attack had been launched by botnets that primarily utilized compromised IoT devices, and was seen by some as ushering in a new era of Internet security woes.

  • This Is Why Half the Internet Shut Down Today [Update: It’s Getting Worse]

    Twitter, Spotify and Reddit, and a huge swath of other websites were down or screwed up this morning. This was happening as hackers unleashed a large distributed denial of service (DDoS) attack on the servers of Dyn, a major DNS host. It’s probably safe to assume that the two situations are related.

  • Major DNS provider Dyn hit with DDoS attack

    Attacks against DNS provider Dyn continued into Friday afternoon. Shortly before noon, the company said it began "monitoring and mitigating a DDoS attack" against its Dyn Managed DNS infrastructure. The attack may also have impacted Managed DNS advanced service "with possible delays in monitoring."

  • What We Know About Friday’s Massive East Coast Internet Outage

    Friday morning is prime time for some casual news reading, tweeting, and general Internet browsing, but you may have had some trouble accessing your usual sites and services this morning and throughout the day, from Spotify and Reddit to the New York Times and even good ol’ For that, you can thank a distributed denial of service attack (DDoS) that took down a big chunk of the Internet for most of the Eastern seaboard.

    This morning’s attack started around 7 am ET and was aimed at Dyn, an Internet infrastructure company headquartered in New Hampshire. That first bout was resolved after about two hours; a second attack began just before noon. Dyn reported a third wave of attacks a little after 4 pm ET. In all cases, traffic to Dyn’s Internet directory servers throughout the US—primarily on the East Coast but later on the opposite end of the country as well—was stopped by a flood of malicious requests from tens of millions of IP addresses disrupting the system. Late in the day, Dyn described the events as a “very sophisticated and complex attack.” Still ongoing, the situation is a definite reminder of the fragility of the web, and the power of the forces that aim to disrupt it.

  • Either IoT will be secure or the internet will be crippled forever

    First things first a disclaimer. I neither like nor trust the National Security Agency (NSA). I believe them to be mainly engaged in economic spying for the corporate American empire. Glenn Greenwald has clearly proven that in his book No Place to Hide. At the NSA, profit and power come first and I have no fucking clue as to how high they prioritize national security. Having said that, the NSA should hack the Internet of (insecure) Things (IoT) to death. I know Homeland Security and the FBI are investigating where the DDoS of doomsday proportions is coming from and the commentariat is already screaming RUSSIA! But it is really no secret what is enabling this clusterfuck. It’s the Mirai botnet. If you buy a “smart camera” from the Chinese company Hangzhou XiongMai Technologies and do not change the default password, it will be part of a botnet five minutes after you connect it to the internet. We were promised a future where we would have flying cars but we’re living in a future where camera’s, light-bulbs, doorbells and fridges can get you in serious trouble because your home appliances are breaking the law.

  • IoT at the Network Edge

    Fog computing, also known as fog networking, is a decentralized computing infrastructure. Computing resources and application services are distributed in logical, efficient places at any points along the connection from the data source (endpoint) to the cloud. The concept is to process data locally and then use the network for communicating with other resources for further processing and analysis. Data could be sent to a data center or a cloud service. A worthwhile reference published by Cisco is the white paper, "Fog Computing and the Internet of Things: Extend the Cloud to Where the Things Are."

    An Intel developer has published testing patches for providing a SoundWire bus driver within the Linux kernel, which implements the MIPI SoundWire 1.1 specification.

    For those unfamiliar with SoundWire as was I when coming across these patches, "The SoundWire protocol is a robust, scalable, low complexity, low power, low latency, two-pin (clock and data) multi-drop bus that allows for the transfer of multiple audio streams and embedded control/commands. SoundWire provides synchronization capabilities and supports both PCM and PDM, multichannel data, isochronous and asynchronous modes. SoundWire does borrow a number of concepts from existing interfaces such as HDAudio, AC97, SLIMbus, which already provide control/audio on the same wires, or legacy interfaces such as I2C/I2S, TDM, PDM."

  • Why GNU/Linux ports can be less performant, a more in-depth answer
    When it comes to data handling, or rather data manipulation, different APIs can perform it in different ways. In one, you might simply be able to modify some memory and all is ok. In another, you might have to point to a copy and say "use that when you can instead and free the original then". This is not a one way is better than the other discussion - it's important only that they require different methods of handling it. Actually, OpenGL can have a lot of different methods, and knowing the "best" way for a particular scenario takes some experience to get right. When dealing with porting a game across though, there may not be a lot of options: the engine does things a certain way, so that way has to be faked if there's no exact translation. Guess what? That can affect OpenGL state, and require re-validation of an entire rendering pipeline, stalling command submission to the GPU, a.k.a less performance than the original game. It's again not really feasible to rip apart an entire game engine and redesign it just for that: take the performance hit and carry on. Note that some decisions are based around _porting_ a game. If one could design from the ground up with OpenGL, then OpenGL would likely give better performance...but it might also be more difficult to develop and test for. So there's a bit of a trade-off there, and most developers are probably going to be concerned with getting it running on Windows first, GNU/Linux second. This includes engine developers.
  • Why Linux games often perform worse than on Windows
    Drivers on Windows are tweaked rather often for specific games. You often see a "Game Ready" (or whatever term they use now) driver from Nvidia and AMD where they often state "increased performance in x game by x%". This happens for most major game releases on Windows. Nvidia and AMD have teams of people to specifically tweak the drivers for games on Windows. Looking at Nvidia specifically, in the last three months they have released six new drivers to improve performance in specific games.

  • Feral Interactive's Linux ports may come with Vulkan sooner than we thought
  • Using Nvidia's NVENC with OBS Studio makes Linux game recording really great
    I had been meaning to try out Nvidia's NVENC for a while, but I never really bothered as I didn't think it would make such a drastic difference in recording gaming videos, but wow does it ever! I was trying to record a game recently and all other methods I tried made the game performance utterly dive, making it impossible to record it. So I asked for advice and eventually came to this way.
