Riverside Plaza Memory Sketch Every day for the past three months I have drawn some scene or event that I saw that day, purely from memory. Usually this is something I saw on the way to work, or, if I'm home that day, something I saw when out for a run or a walk somewhere in the neighborhood. Since I usually make the drawing at the end of the day, several hours will have passed by the time I get around to recording what I saw. To ....

I have some apps written in Go, which I deliver as binaries for each platform using GitHub releases. Until now, I was doing it with a very simple shell script.

Happy Holidays! I’m going to need a minute to blow the dust off my keyboard here, I haven’t posted in an inexcusably long time. Accordingly, I won’t bother with excuses, I’ll just get along with the post. To start, a relevant question I received: Hi Brandon, just wondering if you’ll convert your blog into a travel blog if and when you give up the truck to travel? This is probably in reference to the time I was figuring out when..

There is a strain of thought in the web development community that believes there's a tension between having comprehensive developer tools and delivering good user experiences: This is exactly backwards. At the scale of the entire web, better tools are the only way to deliver better experiences. The

The longer I spend as a software engineer, the more obsessive I get about testing. I fully subscribe to the definition of legacy code as “code without an automated test suite.” I’m convinced that the best thing you can do to encourage fast progress in a test suite is to design for testing and have a fast, reliable, comprehensive test suite. But for all that, I’ve never really subscribed to any of the test-driven-development manifestos or pr..

For the past years, I’ve done a “year in review” blog post, and of course this one is for 2016! It’s a great way to reflect on the events that have happened during the year, and to honest, is actually a lot of fun! Just a quick disclaimer: I have no intention of talking about the shallow-but-popular celebrity death fixation that has taken over the Internet (must be a millennial thing). That being said, when I heard that Prince died, i..

Racket is an impressive language and ecosystem. Compared to Python, Racket (an evolution of Scheme R5RS is three years younger. It is as concise and expressive as Python but with much more reasonable syntax and semantics. Racket is also faster in many cases due in part to: JIT compilation on x86 platforms support for both concurrency and parallelism support for optimizing statically-typed code Furthermore, the built-in web ser....

Much of my professional work for the last 10+ years has revolved around handling, importing and exporting CSV files. CSV files are frustratingly misunderstood, abused, and most of all underspecified. While RFC4180 exists, it is far from definitive and goes largely ignored. Partially as a companion piece to my recent post about how CSV is an encoding nightmare , and partially an expression of frustration, I've decided to make a list of ....

In the previous post, we discussed the performance space of the minimum function which was implemented via a simple ternary operator and with the help of bit magic. Now we continue to talk about performance and bit hacks. In particular, we will divide a positive number by three: uint Div3Simple ( uint n ) => n / 3 ; uint Div3BitHacks ( uint n ) => ( uint )(( n * ( ulong ) 0xAAAAAAAB ) >> ..
