Writing a resume can be a time consuming task involving many rounds of proofreading, recollection, and wordsmithing. Alongside the content, the format of a resume carries a lot of weight. Many people start out writing their resume in Microsoft Word. As their resume evolves, they begin to fiddle with settings buried deep within Words’ menus. It can become tedious. You may have heard of LaTeX. LaTeX gives you fine-grained control that, at least for a programmer, may be easier to grok than clicking through a series of nested menus. This article takes a look at a LaTeX resume template in the style of Gayle McDowell’s “This Is What a GOOD Resume Should Look Like”. You’ll also see the tools and workflow that simplify resume development in LaTeX. ...

Not long ago, a project that involved a low latency app running on a Beaglebone Black (BBB) came up at work. The minimal latency requirement drove the decision to run the BBB with a PREEMPT_RT patched kernel. Luckily, Robert C. Nelson, one of the Beaglebone Black maintainers, maintains a set of scripts for building a kernel specifically for the BBB. Among the many kernel versions offered are variants that have had the PREEMPT_RT patches already applied! The goal is simple: flash the BBB with the latest console image rootfs and Linux kernel (RT patches included). ...

If you grew up gaming in the 00’s and even into the 10’s, you probably have heard of Runescape. Even in 2023, Runescape remains one of the world’s most popular MMOs. The game has evolved significantly over the past 20-ish years of its existence and continues to have one of the most active online communities of any MMO. There’s two main forks of the game: Old School Runescape (OSRS) and Runescape 3 (RS3). Both versions of Runescape have game clients. There’s a Java based, free, and open source client called RuneLite for OSRS. Runescape 3 has the C++ NXT Client. I like to play both versions of the game on a Fedora box. It would be nice not to have to install a plethora of dependencies to support either client (one of which is only officially supported on Debian based distributions). ...

Where does a newbie start their journey into the Linux kernel? Device drivers is the most common answer. Despite its age, Linux Device Drivers 3rd Edition (LDD3) remains one of the best options for learning about device drivers. There are challenges in using such an old text. LDD3’s code examples target the 2.6.10 kernel. At the time of this writing, the kernel is at version 5.19! That said, fixing API deltas just adds to the fun. This article talks about setting up an environment for LDD3 experimentation and the LDD3 experience itself. ...

At the beginning of 2022, I set a personal goal to implement a bare bones OS. The first step was to define what success would look like for the project. The goal is to create an OS that could allocate a single process that adds two numbers and prints the result to the screen. It took a month long journey into the world of x86 emulators, NASM assembly, and architecture reference manuals to get remotely close. ...
