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.

Zapcc Liberated, HMM and GPL

  • Zapcc high-speed C++ compiler now open source
    Zapcc, a caching C++ compiler built for speed, has gone open source. Ceemple Software, Zapcc’s builder, claims the compiler offers dramatic improvements in both incremental and full builds compared to building with Clang 4.0 and Clang 5.0. Based on heavily modified code from the Clang compiler project, Zapcc uses an in-memory compilation cache in a client-server architecture. All compilation information is remembered between runs.
  • Heterogeneous memory management meets EXPORT_SYMBOL_GPL()
    One of the many longstanding — though unwritten — rules of kernel development is that infrastructure is not merged until at least one user for that infrastructure exists. That helps developers evaluate potential interfaces and be sure that the proposed addition is truly needed. A big exception to this rule was made when the heterogeneous memory management (HMM) code was merged, though. One of the reasons for the lack of users in this case turns out to be that many of the use cases are proprietary; that has led to some disagreements over the GPL-only status of an exported kernel symbol. The HMM subsystem exists to support peripherals that have direct access to system memory through their own memory-management units. It allows the ownership of ranges of memory to be passed back and forth and notifies peripherals of changes in memory mappings to keep everything working well together. HMM is not a small or simple subsystem, and bringing it into the kernel has forced a number of low-level memory-management changes. After a multi-year development process, the core HMM code was merged for the 4.14 kernel, despite the lack of any users.

Software: elementary OS Software, Unified Modeling Language (UML), PulseAudio 12.0 and Zstd

  • An Awesome List of Apps & Resources for elementary OS
    It is barely up to a day since I put up a positive review of elementary OS which is well deserved because it has come a long way from what it was 2 years ago when FossMint checked it out. The good news I’ve got for you today is that the developers have published a page on GitHub that contains “curated list of awesome applications, tools and shiny things for elementary OS”. They are grouped into categories for easy selection, are all open source, and clicking on the green tick icons will direct you to the app on elementary OS’s AppCenter.
  • Best Free Unified Modeling Language Tools
    Unified Modeling Language (UML) is a general-purpose, modeling language designed to provide a standard way for visualizing, specifying, constructing, and documenting the artifacts of distributed object systems. It’s the industry standard modeling language for software engineering. The aim of UML is to give software engineers, agile and small development teams, and system architects useful tools for analysis, design, and implementation of software-based systems. It also provides modeling business and similar processes. The language helps to visualize your object-oriented design and communicate with others. It offers limited use for other programming paradigms.
  • PulseAudio 12.0 release notes
    When playing videos, it's important that the audio latency is known so that the video can be synchronized accurately. PulseAudio doesn't get good latency information from the kernel with A2DP playback, which has caused A/V sync problems for many people when watching videos. Now PulseAudio makes the audio buffer in the kernel much smaller, which reduces the problem a lot.
  • PulseAudio 12.0 Released With Many Improvements
    PulseAudio 12.0 was quietly released yesterday as the newest version of this open-source, cross-platform sound server.
  • Zstandard – A Super Faster Data Compression Tool For Linux
    This is known topic and we were using in our day to day activity to compress and decompress files & folders. You might already know zip,tar,7-zip, etc and you would have used all these application for your requirement. Even today also we are going to discuss about similar kind of topic, the tool name is Zstandard. It is super fast data compression tool and compression ratio is very very low. Zstd is lossless data compression algorithm developed by Yann Collet at Facebook. Due to high data compression ratio many of the popular companies and databases are using this tool.

KDE: CMake 3.12 With FreeBSD, Krita 4.1 Beta, C++/Qt

  • CMake 3.12 Update on FreeBSD
    CMake 3.12 has reached rc1. That means we’re testing the update on FreeBSD, and building lots and lots of packages. And, as I’ve written previously, every CMake update triggers a bunch of interesting software findings. As a motto, I’ve got “use it, aggressively improve it” on my website (you can hire me for odd CMake and C++ jobs, too). So hitting compile issues makes me turn to fixing software outside of KDE.

  • The day Kate Gregory enjoyed Qt
    At my company we use C++ for everything, from creating microservices to website backends and as a generator for website frontends, I mean, we do a lot of c++. And because of that we always need more c++ people, but sometimes it’s hard to find developers, but it’s easy to find php / python / javascript ones. Because of that we hired Kate Gregory’s famous c++ course – “Teaching the Teacher” to train current C++ developers to teach C++. (now, that’s a lot of ‘C++’ in a simple sentence, I know. bear with me.) For those that doens’t know, Kate Gregory is somebody that uses, advocates our beloved language even before I was born, and talks all over the world about C++ and also do trainings for companies, And so I enlisted to be her student. It was a really pleasant course going thru how to proplery explain C++ for people that know how to program but don’t know how to C++, and for that I’m grateful. But then when I commented out about Qt in the middle of the class she rolled her eyes, that made me feel a bit uneasy so I talked to her on why the eye-roll. “Qt is not c++”, and I tougth this was already settled down for years, so I asked her if she would be open to see some simple c++ code written in Qt and tell me what she thinks of it. “Well, Yes. but people already tried and it was not good”.

Red Hat: Kubernetes, 'Cloud', and GlusterFS 4.1.0 Release

  • Kubernetes StatefulSet In Action
    Recently, I stumbled upon a StackOverflow question around StatefulSets which made me wonder how well understood they are at large. So I decided to put together a simple stateful app that can be used to experiment with a StatefulSet. In this blog post we will have a closer look at this app and see it in action. If you’re not familiar with StatefulSets, now is a good time for a refresher, consulting the official docs concerning their usage and guarantees they provide.
  • The road to cloud-native applications
    As many organizations do not have the luxury of completely rebuilding their technology foundation or immediately adopting new practices and mindsets, they can embrace gradual yet fundamental shifts in culture, processes, and technology to help support greater velocity and agility. With software increasingly key to how users engage with businesses and how businesses can innovate to stay competitive, organizations should adapt to the new demands of the Digital Economy, such as speeding up application development and delivery. The cloud-native approach describes a way of modernizing existing applications and building new applications based on cloud principles, using services and adopting processes optimized for the agility and automation of cloud computing.
