  • 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. It allows you to search video with in application and select to download the video or other way you can copy and paste the video URL to the application to download the video. Since famous video sites are supported by this application, if some site isn't officially supported, you may still be able to download the videos from it.

  • 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.

​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.

Review: Red Hat Enterprise Linux 8.0

My experiment with RHEL 8 got off to a rough start. Going through the on-line registration process produced some errors and ended up with me getting the wrong ISO which, in turn, resulted in some confusion and delays in getting the distribution installed. Things then began to look up as RHEL 8 did a good job of detecting my system's hardware, registered itself without incident and offered good performance on physical hardware. I was particularly pleased that the distribution appears to detect whether our video card will work well with Wayland and either displays or hides Wayland sessions in response. I did have some trouble with the GNOME Classic Wayland session and GNOME Shell on X.Org was a bit sluggish. However, the Classic session on X.Org and GNOME Shell on Wayland both worked very well. In short, it's worthwhile to explore each of the four desktop options to see what works best for the individual. The big issues I ran into with RHEL were with regards to software management. Both GNOME Software and the Cockpit screen for managing applications failed to work at all, whether run as root or a regular user. When using the command line dnf package manager, the utility failed to perform searches unless run with sudo and occasionally crashed. In a similar vein, the Bash feature that checks for matching packages when the user types a command name it doesn't recognize does not work and produces a lengthy error. There were some security features or design choices that I think will mostly appeal to enterprise users, but are less favourable in home or small office environments. Allowing remote root logins by default on the Workstation role rubs me the wrong way, though I realize it is often useful when setting up servers. The enforced complex passwords are similarly better suited to offices than home users. One feature which I think most people will enjoy is SELinux which offers an extra layer of security, thought I wish the Cockpit feature to toggle SELinux had worked to make trouble-shooting easier. I was not surprised that RHEL avoids shipping some media codecs. The company has always been cautious in this regard. I had hoped that trying to find and install the codecs would have provided links to purchase the add-ons or connect us with a Red Hat-supplied repository. Instead we are redirected through a chain of Fedora documentation until we come to a third-party website which currently does not offer the desired packages. Ultimately, while RHEL does some things well, such as hardware support, desktop performance, and providing stable (if conservative) versions of applications, I found my trial highly frustrating. Many features simply do not work, or crash, or use a lot of resources, or need to be worked around to make RHEL function as a workstation distribution. Some people may correctly point out RHEL is mostly targeting servers rather than workstations, but there too there are a number of problems. Performance and stability are provided, but the issues I ran into with Cockpit, permission concerns, and command line package management are all hurdles for me when trying to run RHEL in a server role. I find myself looking forward to the launch of CentOS 8 (which will probably arrive later this year), as CentOS 8 uses the same source code as RHEL, but is not tied to the same subscription model and package repositories. I am curious to see how much of a practical effect this has on the free, community version of the same software. Read more

GNOME 3.34 Revamps the Wallpaper Picker (And Fixes a Longstanding Issue Too)

The upcoming release of GNOME 3.34 will finally solve a long standing deficiency in the desktop’s background wallpaper management. Now, I’ve written about various quirks in GNOME wallpaper handling before, but it’s the lack of option to pick a random wallpaper from a random directory via the Settings > Background panel that is, by far, my biggest bug bear. Ubuntu 19.04 ships with GNOME 3.32. Here, the only wallpapers available to select via the Settings > Background section are those the system ships with and any top-level images placed in ~/Pictures — nothing else is selectable. So, to set a random image as a wallpaper in GNOME 3.32 I tend to ignore the background settings panel altogether and instead use the image viewer’s File > Set as background… option (or the similar Nautilus right-click setting). Thankfully, not for much longer! Read more
