Linux Devices: Tizen and Pi Zero

Filed under
Linux
  • Samsung Z4 SM-Z400F could be the phone that runs Tizen 3.0 out of the box

    It has been over six months since the launch of the last Tizen Smartphone which was the Samsung Z2 and hence we should soon be seeing a successor to refresh the series. Earlier today, we reported on the leaked specifications and features of one such upcoming Tizen device which is the highly anticipated Samsung Z5. Now, we are getting hints on another Tizen device in the making bearing the Model name SM-Z400F which should logically be the Samsung Z4.

  • Smartphone Game: Dinosaur Simulator: Dino World platform Tizen

    Dino Simulator Dino World is a game where you are a dinosaur causing chaos all over the place. There is one objective and that is to kill, destroy, and to destroy more!!! By causing destuction to innocent people’s lives (and proberably killing those innocent people), you get points! (YAY!).

  • Pi Zero Wireless out now for $10

    Today, on the fifth anniversary of the release of the original Raspberry Pi, the Foundation has released Pi Zero W, a Pi Zero with built-in WiFi and Bluetooth, for $10.

    The original Pi Zero was great (and still is!)—but many people found its lack of wireless connectivity an inconvenience. Now with Zero W, you can connect to the Internet without using any adapters, and you can even use a Bluetooth mouse and keyboard rather than wired USB, or use a Bluetooth speaker for audio.

  • On ZFS in Debian

    I’m currently over at FOSDEM, and have been asked by a couple of people about the state of ZFS and Debian. So, I thought I’d give a quick post to explain what Debian’s current plan is (which has come together with a lot of discussion with the FTP Masters and others around what we should do).

    [...]

    Debian has always prided itself in providing the unequivocally correct solution to our users and downstream distributions. This also includes licenses – we make sure that Debian will contain 100% free software. This means that if you install Debian, you are guaranteed freedoms offered under the DFSG and our social contract.

  • Complying with Creative Commons license attribution requirements in slides and powerpoint

    When I was at Mozilla and WMF, I frequently got asked how to give proper credit when using Creative Commons-licensed images in slideshows. I got the question again last week, and am working on slides right now, so here’s a quick guide.

  • ‘Use open source software for GIS mapping’

    Open sourcing of data for Geographical Information System (GIS) mapping will create a huge potential for employment and transparency in administration, secretary of OSGEO-India V. Ravi Kumar has said.

    Proprietary software for GIS costs up to Rs. .30 lakh. Instead, utilising tools developed using open software and training youth would help in creating employment locally, he said. Money will be spent on those working using GIS but not for the software, he said.

  • Release notes for the Genode OS Framework 17.02

    After the revision of Genode's most fundamental protocols in the previous release it was time to move our attention upwards the software stack. The current release largely revisits the integration of the C runtime with the Genode component API as well as the virtual-file-system (VFS) infrastructure. The two biggest challenges were making Genode's VFS capable to perform I/O asynchronously, and to make the C runtime compatible with the state-machine-based execution model of modern Genode components. This line of work is described in detail in Sections Enhanced VFS infrastructure and New execution model of the C runtime. One particularly exciting result is the brand-new ability to plug the Linux TCP/IP stack as a VFS plugin into any libc-using component by the sole means of component configuration.

  • Genode OS 17.02 Released With Improved VFS, New Input Event Processing

    Genode OS 17.02 has been released today as the latest version of this open-source operating system framework.

    Accomplished for Genode OS 17.02 were ABI improvements, a much better virtual file-system (VFS) implementation, new input event processing capabilities, and a dynamic component-composition engine.

  • heads 0.0 is out!

    heads 0.0 is a preview live CD of what heads is going to be about. This release is not intended to be used from a security point of view, but as a showcase and testing point of view.

    I am not even completely sure everything is torified, but hey, that's what testing is for, no?

  • IKEA's Idealistic Open Source Garden Orb
  • Denmark’s draft IT architecture open for comment

    Denmark’s Agency for Digitisation (Digitaliseringsstyrelsen - DIGST) is inviting comments on its draft IT architecture for digitalisation of the public sector. The document sets out the IT principles for the country’s 33 digitisation initiatives.

  • Norway working on first IT procurement frameworks

    Norway’s government procurement centre (ANS) and the Agency for Public Management and e-Government (Difi) are preparing the country’s first procurement frameworks related to IT. The first call, on telephony services, will be published in the next few days. The second call, for telephony and PC workstations, is expected around 24 April. Calls will be published on both Norway’s and Europe’s procurement portals, Doffin and Ted.

  • France prepares next Open Government action plan

    The 2017-2019 Open Government Action Plan is being prepared by the government modernisation unit (Secretariat-General for Government Modernisation, SGMAP). This week, on Tuesday, SGMAP is hosting a public workshop, where it will present a draft of the plan. The final text is expected in September.

  • Make food production data open source, urges MIT Media Lab

    Agriculture production data should be public and the open source movement should be the model for analysing it, according to the Open Agriculture initiative at MIT Media Lab.

    This could involve making the data from every farming IoT sensor public - so you could use the climate data to understand how best to grow what and where, or use other IoT data points to trace where the food has come from across the whole supply chain.

  • EU updates smartphone secure development guideline

    The European Union Agency for Network and Information Security (ENISA) has published an updated version of its Smartphone Secure Development Guidelines. This document details the risks faced by developers of smartphone application, and provides ways to mitigate these.

  • CloudLinux 7 Users Get New Beta Linux Kernel Update That Addresses CVE-2017-6074

    CloudLinux's Mykola Naugolnyi announced today the availability of a new Beta kernel for the CloudLinux 7 operating system series, which patches a recently discovered and critical security flaw.

  • Linus Torvalds shrugged off warnings about 'insecure' SHA-1 in 2005

    LINUX FOUNDER Linus Torvalds was warned in 2005 that the use of the SHA-1 hash to sign code in Linux and Git was insecure and urged to shift to something better protected, but rejected the advice outright.

    Free software evangelist John Gilmore warned Torvalds ten years ago that "SHA1 has been broken; it's possible to generate two different blobs that hash to the same SHA1 hash".

    Gilmore penned his warning to Torvalds in April 2005, when MD5 had already been cracked and SHA1 remained "hard to crack" - but still crackable.

  • Subversion SHA1 Collision Problem Statement — Prevention and Remediation Options

    You probably saw the news last week that researchers at Google had found a scenario where they were able to break the SHA1 algorithm by creating two PDF files with differing content that produced the same hash. If you are following this story then you may have also seen that the Webkit Subversion repository had problems after a user committed these example files to their repository so that they could be used in test cases for SHA1 collisions.

  • making git-annex secure in the face of SHA1 collisions

    git-annex has never used SHA1 by default. But, there are concerns about SHA1 collisions being used to exploit git repositories in various ways. Since git-annex builds on top of git, it inherits its foundational SHA1 weaknesses. Or does it?

  • SSH Fingerprint Verification via Tor

    OpenSSH (really, are there any other implementations?) requires Trust on First Use for fingerprint verification.

    Verification can be especially problematic when using remote services like VPS or colocation.

    How can you trust that the initial connection isn’t being Man In The Middle’d?

  • Almost all Windows vulnerabilities are enabled by liberal 'admin rights'

    NEARLY OF THE VULNERABILITIES THAT AFFECT Microsoft's Windows operating system could be mitigated through a little careful control.

    Avecto, a security company, is the source of the latest revelation in this direction, and it says that 94 per cent of security problems could have been killed off if admin rights had been removed from the affected computer.

    This makes a lot of sense, since a computer that cannot be molested by a user cannot be molested by a third party. 94 per cent is just one example of the differences that can be made and Avecto says that in the case of Internet Explorer 100 per cent of risks are mitigated when rights are removed.

  • More on Bluetooth Ingenico Overlay Skimmers

    This blog has featured several stories about “overlay” card and PIN skimmers made to be placed atop Ingenico-brand card readers at store self-checkout lanes. I’m revisiting the topic again because a security technician at a U.S.-based retailer recently shared a few photos of several of these devices pulled from compromised card terminals, and the images and his story offer a fair bit more detail than in previous articles.

    As I mentioned in my previous post about the New Users Panel, we are happy to be able to include a new Printers panel in GNOME 3.24.

    The Printers panel is also part of the GNOME Control Center redesign effort which intents to introduce the new shell in 3.26

  • Profiling Flatpak’d applications
  • Attended FOSDEM 2017

    Containerised applications solve these issues. Maybe. He mentioned Flatpak, snappy, and Appimage. The former is the oldest technology dating all the way back to 2003. The solutions have in common that they bundle the app and run it in some kind of container or sandbox. From his criteria, the compatibility issue is solved, because the libraries are in the bundles. Portability is solved, because all dependencies are shipped in the bundle. And the pace of change is up to the app developer.

  • Custom terminal titles are back in Fedora

    Almost four years ago, in GNOME 3.12, the ability to have custom terminal titles was removed from gnome-terminal. As is wont to happen, users who dealt with scores of similar looking terminal tabs and windows were quick to express their grief at this loss.

Are physical keyboards for mobile devices making a comeback? TCL and BlackBery just launched a new phone with a QWERTY keyboard. A keyboard module for the Moto Z smartphone is generating some buzz. And an Indiegogo campaign for a 7 inch, pocket-sized Windows notebook has raised over $1.7 million (so far).

Now the folks at UK-based Planet Computers want to bring back the idea of a small, clamshell computer. And they’ve partnered with the designer of the classic Psion Series 5 to do it.

  • Deliverable 1 : [✓]
    Seems okay, far better than the initial results. Although I should say, I deviated from what I thought I would need to write. First I assumed that I don’t have to write another boost::graph wrapper for KisPaintDevice, but I had to. That was one heck of an experience. In one of the last few posts, I ranted on Dmitry’s interpretation of the Graph, turns out we were on the same page but I understood his explanation the wrong way. I should put more attention to details from now on I guess. All the pixels are connected to each other, but they only have an edge between them if they are adjacent. If in center, the out degree would be 8, if in corners, 3 and if in edges, 5. There are some other cases too, but I will leave them for the moment. While writing the wrapper, I also got to know some of the cool features and techniques of C++, which I will be writing posts on as soon as I get some time, concepts, traits, avoiding virtual functions and what not. It is commendable that how boost approaches boost::astar_search, there is not a single virtual function, you don’t have to inherit anything (you can though for safety), just templates and traits, you are done.
  • Go Creeping In
    I’ve seen the inside of the Google and Amazon tech stacks. There are common threads that run through them and also, I bet, through most BigTechCos. Here and there down the stack is a lot of C++ and vestigial remnants from earlier days, Perl or PHP or whatever. Out in front of humans, of course, JS. But in between, there are oceans and oceans of Java; to a remarkable degree, it runs the Internet. Except for, here and there, you find a small but steadily increasing proportion of Go.
  • Stand by for FPR14 SPR1 chemspill
    Mozilla has shipped a fix for MFSA2019-18 in Firefox 67.0.3 and 60.7.1. This exploit has been detected in the wild, and while my analysis indicates it would require a PowerPC-specific attack to be exploitable in official TenFourFox builds (the Intel versions may be directly exploited, however), it could probably cause drive-by crashes and we should therefore ship an urgent fix as well. The chemspill is currently undergoing confidence tests and I'm shooting to release builds before the weekend. For builders, the only change in FPR14 SPR1 is the patch for bug 1544386, which I will be pushing to the repo just as soon as I have confirmed the fix causes no regressions.

All Linux, all the time: Supercomputers Top 500

Starting at the top, two IBM-built supercomputers, Summit and Sierra, at the Department of Energy's Oak Ridge National Laboratory (ORNL) in Tennessee and Lawrence Livermore National Laboratory in California, respectively to the bottom -- a Lenovo Xeon-powered box in China -- all of them run Linux. Linux supports more hardware architectures than any other operating system. In supercomputers, it supports both clusters, such as Summit and Sierra, the most common architecture, and Massively Parallel Processing (MPP), which is used by the number three computer Sunway TaihuLight. When it comes to high-performance computing (HPC), Intel dominates the TOP500 by providing processing power to 95.6% of all systems included on the list. That said, IBM's POWER powers the fastest supercomputers. One supercomputer works its high-speed magic with Arm processors: Sandia Labs' Astra, an HPE design, which uses over 130-thousand Cavium ThunderX2 cores. And, what do all these processors run? Linux, of course. . 133 systems of the Top 500 supercomputers are using either accelerator or co-processor setups. Of these most are using Nvidia GPUs. And, once more, it's Linux conducting the hardware in a symphony of speed. Read more

Red Hat and SUSE Leftovers

  • Are DevOps certifications valuable? 10 pros and cons
  • Kubernetes 1.15: Enabling the Workloads
    The last mile for any enterprise IT system is the application. In order to enable those applications to function properly, an entire ecosystem of services, APIs, databases and edge servers must exist. As Carl Sagan once said, “If you wish to make an apple pie from scratch, you must first invent the universe.” To create that IT universe, however, we must have control over its elements. In the Kubernetes universe, the individual solar systems and planets are now Operators, and the fundamental laws of that universe have solidified to the point where civilizations can grow and take root. Discarding the metaphor, we can see this in the introduction of Object Count Quota Support For Custom Resources. In English, this enables administrators to count and limit the number of Kubernetes resources across the broader ecosystem in a given cluster. This means services like Knative, Istio, and even Operators like the CrunchyData PostgreSQL Operator, the MongoDB Operator or the Redis Operator can be controlled via quota using the same mechanisms that standard Kubernetes resources have enjoyed for many releases. That’s great for developers, who can now be limited by certain expectations. It would not benefit the cluster for a bad bit of code to create 30 new PostgreSQL clusters because someone forgot to add a “;” at the end of a line. Call them “guardrails” that protect against unbounded object growth in your etcd database.

    This series of blog posts and corresponding talks aims to provide you with a pragmatic view on containers from a historic perspective. Together we will discover modern cloud architectures layer by layer, which means we will start at the Linux Kernel level and end up at writing our own secure cloud native applications. Simple examples paired with the historic background will guide you from the beginning with a minimal Linux environment up to crafting secure containers, which fit perfectly into todays’ and futures’ orchestration world. In the end it should be much easier to understand how features within the Linux kernel, container tools, runtimes, software defined networks and orchestration software like Kubernetes are designed and how they work under the hood.
