  • 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.

  • 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).

  • [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.

  • 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.

  • 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.

  • Where Did That Software Come From?
    The article explores how cryptography, especially hashing and code signing, can be use to establish the source and integrity. It examines how source code control systems and automated build systems are a key part of the software provenance story. (Provenance means “a record of ownership of a work of art or an antique, used as a guide to authenticity or quality.” It is increasingly being applied to software.)

  • Vulkan 1.0.64 Adds In Another AMD-Developed Extension
    Vulkan 1.0.64 is out this weekend as the newest specification refinement to this high-performance graphics/compute API. As usual, most of the changes for this minor Vulkan revision are just documentation clarifications and corrections. This week's update brings just under a dozen fixes.
  • NVIDIA TX2 / Tegra186 Display Support Isn't Ready For Linux 4.15
    While the Jetson TX2 has been out since this past March and it's a phenomenal ARM development board, sadly the Direct Rendering Manager (DRM) driver support for it still isn't ready with the mainline Linux kernel. Thierry Reding of NVIDIA sent in the Tegra DRM driver changes for DRM-Next that in turn is staged for Linux 4.15. Reding commented that there is prepatory work for the TX2 (Tegra186) but it's not all ready for upstream yet.

Ubuntu: Mir running on Fedora and Ubuntu 17.10 Guidance

  • Mir running on Fedora
    Last week we released Mir 0.28 and this week we settled down to tidy up a few bugs fixes and feature requests that didn’t make the release. I’ve started collecting these for a Mir 0.28.1 release to come in the next few weeks. The most interesting of these comes from conversations at the Ubuntu Rally: there were several requests from community members around getting Mir working (or even building!) on other distributions.
  • Ubuntu Developer Gets Mir Running On Fedora
    Lead Mir developer Alan Griffiths has spent the time getting the Mir display server running on Fedora. This is part of a broader feature request of getting Mir running on more Linux distributions than just Ubuntu. The changes to get Mir running on at least Fedora should be merged for the upcoming Mir 0.28.1 point release. Mir 0.28.1 will also incorporate other bug fixes.
