  • The Atom Editor

    I didn’t set out to write a blog post about a text editor. I was going to write about one of the other awesome projects that the Ops team is doing here at Wombat. Along the way I decided to give Atom a chance again and I’m glad I did. I enjoyed it enough that I thought I would defer my post about automating my “Ops Environment” on a mac (I promise, I’ll do that one soon-ish) in favor of this.

  • Quick Update: ClipGrab and PlayOnLinux Applications Are Now Available For ALL Ubuntu Versions

    ClipGrab is fairly popular application to download video from famous sites of the Internet.

  • QNX 7 Can Be Fitted With A Qt5 Desktop

    While QNX remains targeted as an operating system for mobile/embedded solutions, a BlackBerry developer in his spare time has fitted QNX 7 with a Qt5 desktop.

    QNX 6 and prior had a desktop option, but was removed in QNX 7, which was released this past March. QNX 7.0 also brought support for 64-bit (and maintaining 32-bit) Intel x86 and ARM platforms along with C++14 support. For those wanting to experiment with QNX 7, a BlackBerry kernel developer has been working on making this operating system more desktop friendly.

  • Building a BlackBerry QNX 7 Desktop

    Having Qt allowed me to port one of my favourite applications, SpeedCrunch. It was a simple matter of running ‘qmake’ followed by ‘make’. Next, I ported the QTermWidget library so that I could have terminal windows.

  • State of Sway April 2017

    Development on Sway continues. I thought we would have slowed down a lot more by now, but every release still comes with new features - Sway 0.12 added redshift support and binary space partitioning layouts. Sway 0.13.0 is coming soon and includes, among other things, nvidia proprietary driver support. We already have some interesting features slated for Sway 0.14.0, too!

    Today Sway has 21,446 lines of C (and 4,261 lines of header files) written by 81 authors across 2,263 commits. These were written through 653 pull requests and 529 issues. Sway packages are available today in the official repos of pretty much every distribution except for Debian derivatives, and a PPA is available for those guys.

  • Surface revenue does a U-boat, and dives

    Revenue generated by Microsoft's Surface hardware during the March quarter was down 26% from the same period the year before, the company said yesterday as it briefed Wall Street.

    For the quarter, Surface produced $831 million, some $285 million less than the March quarter of 2016, for the largest year-over-year dollar decline ever.

  • Acer said to me: "do not use our products with Linux. Find another manufacturer"

    Last year, I bought an Acer notebook and it came with Windows 10.

    As I didn't want spyware neither bloatware, I got Linux installed and asked for a refund of the OEM license. After a little of talking, they were wanting to charge me US$100 (to remove the license, which I already had wiped, as I got FDE Linux installed) to refund US$70 of the OEM license.

    This year, wondering to buy a new Acer notebook, I asked them again if they would refund me the OEM license without all the hassle (as they did pay me the US$70, without me having to pay the US$100).

  • LibreOffice the better Office, really?
  • A serious bug in GCC

    This post is to inform you about a bug in GCC that may cause memory (or other resource) leaks in your valid C++ programs.

  • [Older] Supporting Bangladesh’s software industry with Indian cooperation

    It’s worth noting that the word “free” in free/open-source software implies not just free of cost, but also freedom from commercial dependence upon multi-national software vendors.

    To emphasise this, the biography of Richard Stallman, the founder of the free software movement which ultimately produced the Linux operating system, is titled Free as in Freedom.

    In fact, it is impossible to run a modern government without computers; so it should not be acceptable that sovereign nations like Bangladesh be forever dependent on foreign IT vendors, especially when the Linux alternative offers both freedom and zero-cost.

Security Leftovers

Security
  • Is there any way to truly secure Docker container contents?

    All this adds up to a lot of work, which is not taken care of for you by default in Docker. It is no surprise that many Docker images are insecure, given this picture. The unfortunate reality is that many Docker containers are running with known vulnerabilities that have known fixes, but just aren’t, and that’s sad.

  • Compromise recovery on Qubes OS

    Occasionally fuckups happen, even with Qubes (although not as often as some think).

    What should we – users or admins – do in such a situation? Patch, obviously. But is that really enough? What good is patching your system if it might have already been compromised a week earlier, before the patch was released, when an adversary may have learned of the bug and exploited it?

    That’s an inconvenient question for many of us – computer security professionals – to answer. Usually we would mutter something about Raising the Bar(TM), the high costs of targeted attacks, attackers not wanting to burn 0-days, or only nation state actors being able to afford such attacks, and that in case one is on their list of targets, the game is over anyway and no point in fighting. Plus some classic cartoon.

    While the above line of defense might work (temporarily), it really doesn’t provide for much comfort, long term, I think. We need better answers and better solutions. This post, together with a recently introduced feature in Qubes OS 3.2 and (upcoming) 4.0, is an attempt to offer such a solution.

    “A lot of these systems are still Windows 95 or 98, and that’s OK—if they’re not connected to the internet,” Haegley added.

  • VM escape - QEMU Case Study

    In this paper, we provide a in-depth analysis of CVE-2015-5165 (a memory-leak vulnerability) and CVE-2015-7504 (a heap-based overflow vulnerability), along with working exploits. The combination of these two exploits allows to break out from a VM and execute code on the target host. We discuss the technical details to exploit the vulnerabilities on QEMU's network card device emulation, and provide generic techniques that could be re-used to exploit future bugs in QEMU.

  • CIA’s anti-leaking tool leaked as ‘whistleblowers watch the watchers’

    Former MI5 intelligence officer Annie Machon and retired US Army Colonel Ann Wright, who is also a retired US State Department official, shared their views on these and other questions with RT.

    On Friday, WikiLeaks released a series of documentations on a US Central Intelligence Agency (CIA) project known as ‘Scribbles,’ which was allegedly created to allow ‘web beacon’ tags to be embedded “into documents that are likely to be copied.”

    WikiLeaks began publishing a huge cache of secret documents on the CIA named ‘Vault 7’ in March.

  • Vault 7: CIA tool to track people through Word docs released

    The documentation says: "Scribbles (SCRIB) is a document watermarking tool that can be used to batch process a number of documents in a pre-seeded input directory. It generates a random watermark for each document, inserts that watermark into the document, saves all such processed documents in an output directory, and creates a log file which identifies the watermarks inserted into each document."

    It says the tool was successfully tested on Office 2013 (on Windows 8.1 x64), documents from Office versions 97-2016 (Office 95 documents will not work!) and documents that are not locked forms, encrypted, or password-protected.

    There is a limitation to the Scribbles system: if a document that has the watermarks in it and is opened in OpenOffice, LibreOffice the watermark images and URLs may become visible.

  • The US Takes On the World in NATO’s Cyber War Games

    Last year, Capt. Sean Ruddy and his team of operator-soldiers from the US Cyber Brigade entered a Locked Shields, a NATO-organized cyber-defense war game that pits teams from dozens of countries against “live-fire” attacks. It was their first time. And of the 19 countries represented, the US finished dead last. This week, they got their shot at redemption.

Anbox Runs Android In Your Linux Without Emulation

​In a recent article, we talked about android emulators for Ubuntu or Linux in general. Most of the time we need to play a game or try some applications on android or even when we don’t have a smartphone we opt to use an emulator to try applications. A fan on facebook let us know about Anbox and asked for the tutorial on Anbox installation in Linux. So here you have how to install Anbox in Linux.

Python Programming Leftovers

  • Pylint: Making your Python code consistent

    Pylint is a higher-level Python style enforcer. While flake8 and black will take care of "local" style: where the newlines occur, how comments are formatted, or find issues like commented out code or bad practices in log formatting. Pylint is extremely aggressive by default. It will offer strong opinions on everything from checking if declared interfaces are actually implemented to opportunities to refactor duplicate code, which can be a lot to a new user. One way of introducing it gently to a project, or a team, is to start by turning all checkers off, and then enabling checkers one by one. This is especially useful if you already use flake8, black, and mypy: Pylint has quite a few checkers that overlap in functionality.

  • PyDev of the Week: Sophy Wong

Proper Linux Screen Sharing Coming to Chromium & Electron Apps like Discord

A patch to add ‘screen enumeration’ to the Chromium browser is currently pending merge upstream. Once this fix is accepted Chromium and Chromium-based apps (like Discord) will finally support full screen sharing on Linux in a manner similar to that on Windows and macOS. Not being a multi-monitor user, or someone who shares their screen often, I wasn’t aware of this particular limitation until recently. So I’ll explain. Read more

Firefox 70 Is Now Available to Download with Fresh New Look, Extended Dark Mode

Judging by the version number, you would think that Firefox 70 is a massive update to the open-source and cross-platform web browser built by Mozilla, but it's not really a major release. However, it does bring some a fresh new look for its icon, new welcome screen, and an extended dark mode for the built-in pages. So the first thing you'll notice after installing Firefox 70, which you can download right now for GNU/Linux, macOS, and Windows systems, it's the new Firefox icon that was unveiled by Mozilla a few months ago. In addition, you'll notice that all of Firefox's built-in pages now follows the system dark mode preference and a new welcome screen will help you setup Firefox faster. Read more
