Has it already been a month since my last update? I guess March flew right by. Enarx Most of my time at work has been spent porting code into the main Enarx repository to form the basis for an Enarx Keep for SEV. A "keep" is a trusted execution environment that Enarx can deploy a … Continue reading Status Update: March, 2020
Status Update: February, 2020
I want to start blogging more. I'll be the first to admit that I haven't been trying particularly hard (or at all) to write for my blog these past few several months. This is true for my side projects as well, one of which I'd like to send upstream some day. I've been busy adjusting … Continue reading Status Update: February, 2020
Linux Kernel Development Workflow: Testing Changes in a Virtual Machine
I think we can all agree that the faster a code-compile-test development cycle is, the better. Working on an operating system kernel like Linux throws a bit of a wrench in the development cycle that most of us are used to simply because Linux expects to be driving some hardware! This means that the kernel … Continue reading Linux Kernel Development Workflow: Testing Changes in a Virtual Machine
Deploying the Telegraf InfluxDB Grafana (TIG) Stack with Docker to Monitor a Linux Host
So I set up an old Dell Optiplex 7010 to be my home Linux development server and decided to use that as an opportunity to start learning Docker so I used that to deploy an IRC bouncer onto my home server. Obviously, the next thing to do would be to deploy monitoring software so that … Continue reading Deploying the Telegraf InfluxDB Grafana (TIG) Stack with Docker to Monitor a Linux Host
How to Set Up an IRC Proxy with Docker
I use IRC to keep in touch with my coworkers. Many of my teammates use an IRC proxy or bouncer to stay connected to the channel so they can get caught up on any chatter or see any messages they received while they were away. In a previous post, Embrace the Remote Development Environment, I … Continue reading How to Set Up an IRC Proxy with Docker
Embrace the Remote Development Environment
A developer's tools are precious because that's how she gets her work done. But what about the development environment? When I was in university, I took the remote Linux servers for granted. I did a lot of development on my laptop. And then my desktop. And then I started using both. I would eventually find … Continue reading Embrace the Remote Development Environment
Test Driven Development in the Clang Compiler
A while back, I participated in a software engineering capstone with a group of other computer science students to complete my degree. Our project was to create a from-scratch implementation of grsecurity's "randstruct" GCC plugin for the Clang compiler. Long story short, we ended up sending out a request for comments (RFC) on the initial … Continue reading Test Driven Development in the Clang Compiler
My Favorite Takeaways from 21st Century C
Look- I'm a big fan of programming books. My most recent foray was into Ben Klemens's 21st Century C. I'm already proficient with C in general, so why read yet another book on it? Well, my learning style is primarily iterative--which I suspect is true for many of us. A little review never hurt anybody. … Continue reading My Favorite Takeaways from 21st Century C
How the Linux Kernel Detects PCI Devices and Pairs Them with Their Drivers
Have you ever wondered how Linux knows what PCI devices are plugged in? How does Linux know what driver to associate with the device when it detects it? In short, here's what happens: During the kernel's init process (init/main.c), various subsystems are brought up according to their "init levels." Among these early subsystems are the … Continue reading How the Linux Kernel Detects PCI Devices and Pairs Them with Their Drivers
Lessons Learned From an Open Source Capstone Project
The last term of my undergraduate Computer Science degree is almost over. Yay! My software engineering capstone project also comes to an academic close in a matter of days and I wanted to take a moment to reflect on some of the key lessons that I’ve learned from this entire process. For the uninitiated, Computer … Continue reading Lessons Learned From an Open Source Capstone Project
