Every so often, a few posts come across my desk at the same time, and it reminds me of how at some basic level, all work is the same work, just manifested in different ways. Checklists and agendas, which are near and dear to my heart, are crucial for communicating and getting things done correctly across a team. They represent an agreement, a contract, reflections of expectations.

When you enter a meeting that has gone off the rails, it’s likely that either someone has torpedoed the agenda or one was never established. Likewise, any time I’ve needed to get a project back in a manageable state, a forced prioritized to-do list is my weapon of choice.

Similarly, sequential logical steps are the bread and butter of processors. Most of my high performance computing architecture course is focused on how processors squeeze every possible optimization out of a program’s instructions. There are dozens of ways that it does this (branch prediction, loop unfurling, data caches, etc), but perhaps most approachable is how a processor issues and executes instructions.

For my first semester at Georgia Tech, I wanted to take two courses that were well-reviewed, challenging, and introduced me to new concepts but that also played to my strengths. The first two months of the semester were bound to be hectic as I balanced gracefully leaving my full-time job of the past 6+ years with starting OMSCS. With that in mind, I ended up taking both of the operating systems courses GT offers online students.

Fortunately, there was only some overlap between the two courses and once I was a full time student my schedule made it easy to cram on the sort of “presumed knowledge” that Advanced Operating Systems (AOS) assumed was rattling around in my brain. There is also a “refresher” course that I would strongly recommend going through if you’re taking this course without GIOS. It’s possible to complete in a weekend and the first week of the course is a perfect time to cram this in. Going through this refresher and honing in on areas of weakness had the added bonus of forcing me to learn topics that pushed me ahead of the curve in a few areas in GIOS, but not so many to make that course redundant.

Similar to GIOS, the course professor (Umakishore Ramachandran) provided excellent lectures with a well-structured course, but was largely absent from managing the day-to-day of the class. While the TA’s in this course were less active than in GIOS, they still capably managed all forum questions and were readily available in Slack. There are four projects (one of which is essentially a warmup for the last project) and two tests. The projects are manageable if you have C/C++ skills, and I found the tests to be easier than those in GIOS (more memorization on these tests and less applied concepts).

Georgia Tech’s Graduate Introduction to Operating Systems (GIOS), a thorough review of the core concepts behind operating systems, came highly recommended by way of OMSCentral and it did not disappoint. The lectures (delivered through Udacity) are well-structured and concise, the projects are enjoyable and go beyond the normal client/server projects in an undergrad OS course, and the course TAs and community are key to making this a top-notch experience. In summary, if you have decent C/C++ experience and either have not taken an operating systems course before or it’s been quite some time since you looked at these dinos, then I’d strongly recommend signing up for CS6200.

Ada Gavrilovska is the course professor, but most of your interactions (asking questions about projects, tests, readings, etc.) are with her teaching assistants. Fortunately, one of the fun parts of OMSCS is that most students and TAs are full-time employees themselves. This means that while the course is driven by TAs, these folks have real-world experience to bring to the table, usually from similar areas of practice.

My first day with LexBlog was sometime in August of 2008. The previous summer I worked at a Hastings (a now, mostly defunct retail chain for movies, books, video games, CDs, and okay coffee), my last retail job. LexBlog, by way of Colin O’Keefe, provided me a route to take the first steps in my career with a part-time editorial position. I began by working on their content aggregator, LexMonitor, covering the work of the largest law firms in the country.

Fast forward eleven years and LexMonitor is a thing of the past at LexBlog, as am I.

On September 26th I walked out of a WeWork in downtown Seattle on what would be my last long walk home after a day at LexBlog. The walk was about five miles, something I’d done countless of times since moving to Seattle in 2013 to work for LexBlog full-time. It was a walk reserved for thinking through especially hard problems or after a long night (and sometimes early morning) of work. This time, it was a walk into a new branch of my personal and professional life.

My morning routine is sacrosanct. Every day, I wake up at the same time, drink the exact same amount of coffee (which is usually just a little too much), take the same bus, and settle into work. I find a great deal of comfort in this routine, which is why the lack of shock to my system over the month of August was itself quite a shock.  On Sunday, July 28th, my wife and I flew up to Anchorage, Alaska and settled in a small Airbnb on the outskirts of town.

This was not a permanent move; in fact I’m already back in Seattle. Our time in Anchorage was limited to a month as Sarah wrapped up a rotation at the Alaska Native Medical Center (ANMC). While her routine was shockingly similar (which is to say, “brutal” – residency is no joke), mine was very different. Gone was the morning commute to the office. My french press had to stay at home, and the view from my office became dominated by a forest filled with vegetation and the occasional moose.

Case in point – a mother and her calf waltzing through our ward 

Other than the change of scenery and slight shift in daily routine, however, my work life remained the same. I may move around, but our platform’s infrastructure and tooling could care less about where my laptop is opened so long as my logins are valid.

I do not own a desktop computer and have not for nearly seven years. Before that, my primary computer was a Dell desktop that my parents bought me as a college graduation present that I augmented with a small notebook computer (at a time when such small laptops were just a novelty).

Even without a desktop computer, my life is full of peripheral devices. Laptops these days are so powerful that most can easily accommodate an additional monitor (if not two), and working in this way usually requires a detached keyboard and mouse.

Today, my mouse’s batteries died. Unlike my keyboard, which is solar powered, my mouse runs on rechargeable batteries, and I often forget to recharge them. When I do, I’m left with just my laptop’s trackpad and a sense of frustration. Continue Reading Technology Advances; the World Remains the Same

This summer, I’ll wrap up a computer science degree from Oregon State University. The experience has been rewarding, difficult, and incredibly eye-opening.

After the first quarter at OSU, I was not sure that the program was for me. While learning C++ was a nice wrinkle, the “Introduction to Programming” courses that served as my welcome were underwhelming. In hindsight, this perspective makes sense as someone that was coming in with years of experience managing and delivering web projects for large clients with large expectations. Learning the structure of for loops, classes, and a brief dalliance into recursion was not really what I had signed up for. However, after the fourth quarter I was trying to plot a path to continue my education far beyond the 15 courses that were required to get another bachelor’s.

It wasn’t the fact that OSU continued to underwhelm that drove me to look beyond the program – quite the opposite. OSU provided a window into a world that I didn’t know existed. It’s fair to say that two years ago I did not know what a computer science degree entailed or what it prepared you for. Two years later and I can’t imagine a world where I don’t continue to explore the field. Continue Reading Finishing One Degree; Starting Another

Before I dive in, I should note that this post was written as LexBlog hits its fifteenth birthday. It’s been my pleasure to work in the Seattle offices at LexBlog for over 6 years. So much of that pleasure stems from truly enjoying the people that work here and overcoming the challenges we face on a regular basis. Here’s to another fifteen for a great company of great people.

There’s a line in Fight Club that I love that comes to mind when thinking about my favorite memories at LexBlog:

I rarely look at C while at the office. In many ways, it’s a language of a bygone era, especially when you’re talking about web application development. Sure, we take advantage of C every day, but write in it? Never.

However, I’ve become fairly proficient in it these past two years and have grown to appreciate the language for what it is: Blazing fast and fine-tuned for several specific use-cases. Unlike JavaScript (my language of choice while at work), C does not come with dozens of associated frameworks that come and go on a moment’s notice. It also doesn’t split its time between the hard logic of an application and managing the user interface. In many ways, C runs the world of computers around us without us even knowing.

The story behind C is the most interesting part of the language. Written in the late 60’s and launched into production around 1972/1973, C was born from necessity. In the late 60’s, Dennis Ritchie and Ken Thompson decided to write an operating system for the PDP-11, Unix (pictured above – it’s the size of a huge refrigerator and it’s processing power isn’t even close to the power of my phone).

I have a great fondness for journalism. The industry, the people, the organizations — it’s all fascinating and vitally important. My political and philosophical leanings lead me to believe that the tradition of having an independent and empowered Fourth Estate is key to a functioning democracy.  Even in the absence of my politics and philosophies, reading the news is fun. I enjoy reading about the experiences of people I’ve never met going to places I’ve never been. How odd.

So to hear that the profession is dying, shrinking, or changing for the worse, and to listen to the narrative get increasingly louder is cause for some concern.
