Computer Equipment and Screen Recording Revisited

It has been about 3 years since my primary hardware machine has been upgraded. I already had 16GB of RAM, two 1920 x 1200 monitors, a Filco mechanical keyboard, and a graphics tablet. OK, I admit that the CPU is showing a little age, but it was an AMD Phenom II X4 965 quad-core processor, and that still has some life left in it.

So I decided to update my graphics card, which was an Nvidia GeForce 440. I do run the Nvidia graphics binary driver (and I'll be delighted to switch to the Nouveau driver when it gets close to equivalent performance). Now, my primary system runs Kubuntu Saucy, with KDE 4.12.3, so a graphics card update should make sense. I'm Not made of money, so cost was definitely a factor.

In fact, I wanted to upgrade to Nvidia's GeForce GTX 780 (TI) card, but at 500-760 US dollars (depending upon configuration), it was just too much.

While I was wrestling with the cost vs benefit ratio, the Nvidia GeForce GTX 750 TI card came out. Priced at $150 US, it seemed like a good deal. But my research indicated the performance of that card wasn't that much above my GeForce 440 card.

So, I opted for the GeForce GTX 770 card, at $330 US. The performance benefit was all I'd hoped for. Recommended.

I've been screen recording some "using Ruby videos". I've blogged here about some screen recorders in the past, and I've used DemoRecorder, which is a commercial product priced at $247.00 US. And I've messed around with ffmpeg, Istanbul, Recorditnow, Recordmydesktop, and Kazam as Open Source and free screen recorder options.

But, I've finally landed on Simple Screen Recorder (SSR) as the best combination of ease of use, configuration, and video and sound quality. The web site is
here.

Along with this, I've recorded also under Microsoft Windows 7. The leading screen recorder there is Camtasia Studio at $299.00. Well, I've spent too much money, and I don't want to buy it (and, I rarely use MS Windows and don't want to invest in that system). So, I've experimented with low cost screen recorder systems under Windows, but haven't found the perfect software for my needs.

Believe me when I say that you can get equivalent or better quality under Linux when screen recording. And far more cheaply.

gtk-recordmydesktop

gtk-recordmydesktop, which is simply to set up and use, has worked quite well for me. Provided you have a good microphone you can produce good screencasts with it.

Announcing the election for the next TDF Board of Directors

On October 18, we officially announced the upcoming election for the next Board of Directors of The Document Foundation, the non-profit entity behind LibreOffice. As per § 7 II of our statutes (binding German version and non-binding English translartion) the Board’s term lasts two years. The current Board started its duty on February 18, 2020. Therefore, the old Board remains in charge until the end of February 17, 2022, so the new Board will be in charge the day after that, which is February 18, 2022. That upcoming term will then (regularly) end on February 17, 2024, so the next election of the Board of Directors will take place before. As per § 6 III, only members of the Board of Trustees of The Document Foundation, as well as current members of any of its bodies, are eligible to be elected into the Board of Directors, and the election is prepared and supervised by the Membership Committee (§ 7 II).

VirtualBox 6.1.28 Released with Initial Support for Linux 5.14 and 5.15 Kernels

VirtualBox 6.1.28 is here about three months after VirtualBox 6.1.26 to introduce initial guest and host support for the Linux 5.14 and 5.15 kernel series. This means that you can now use VirtualBox on GNU/Linux systems powered by Linux kernels 5.14 or 5.15, as well as to run distributions powered by Linux 5.14 or 5.15 kernels inside virtual machines. In addition, this release introduces initial support for the upcoming Red Hat Enterprise Linux 8.5 operating system, improves the detection of kernel modules in Linux hosts to prevent unnecessary rebuilds, fixes a display corruption on Linux Mint systems, and adds bindings support for Python 3.9.

More Mozilla Spying and Management Shuffle

  • William Lachance: Learning about Psychological Safety at the Recurse Center

    Some context: I’m currently working as a software engineer at Mozilla, building out our data pipeline and analysis tooling. I’ve been at my current position for more than 10 years (my “anniversary” actually passed while I was out). I started out as a senior engineer in 2011, and was promoted to staff engineer in 2016. In tech-land, this is a really long tenure at a company. I felt like it was time to take a break from my day-to-day, explore some new ideas and concepts, and hopefully expose myself to a broader group of people in my field. My original thinking was that I would mostly be spending this time building out an interactive computation environment I’ve been working on called Irydium. And I did quite a bit of that. However, I think the main thing I took away from this experience was some insight on what makes a remote environment for knowledge work really “click”. In particular, what makes somewhere feel psychologically safe, and how this feeling allows us to innovate and do our best work. While the Recurse Center obviously has different goals than an organization that builds and delivers consumer software, I do think there are some things that it does that could be applied to Mozilla (and, likely, many other tech workplaces).

  • Best Open Source Security Tools | eSecurityPlanet

    Over the past quarter of a century, the open source movement has gone from strength to strength. But that success and the openness inherent in the community have led to a major challenge – security. The more software that is developed, the greater the likelihood there is for vulnerabilities. To make matters worse, the open source world prides itself on openness and transparency. Therefore, any security vulnerabilities are disclosed publicly. In this age of organized gangs of cybercriminals, that is like placing an ad asking for an attack. This has given rise to a large number of open source security tools. They take care of all aspects of the management of security in open source components, examine dependencies, fix bugs in code, and lower risk.

  • Credit card PINs can be guessed even when covering the ATM pad

    Researchers have proven it’s possible to train a special-purpose deep-learning algorithm that can guess 4-digit card PINs 41% of the time, even if the victim is covering the pad with their hands. The attack requires the setting up of a replica of the target ATM because training the algorithm for the specific dimensions and key spacing of the different PIN pads is crucially important.
