I just got a database less home page for a future SAAS app deployed via HatchBox under Rails 5.x and I thought the differences were significant enough that I should document it. HatchBox is the best tool I've ever found for Rails deploys but knowing all the steps to follow is key. elixi: Other than the Rails 5.2 upgrade step, there aren't many differences between this and Rails 6 but it has been long enough since I've done this that wr....

My toy Lisp fn is an inherently single-threaded language, but with its built-in stack-inspection capabilities, it’s easy to build coroutines on top. The implementation only has about 20 lines of code, including comments. This article contains a simplified implementation in-line. In only rewrote some comments to make more sense in context, and removed confusing technicalities like fn’s custom method call syntax, the use of dynamic-wind....

Freetype, included in the font stack on Unix, is quite complex. There are so many layers to get it to do what it does that it's easy to get lost. From finding the font, to actually rendering it, and everything in between. Like most of the world, I use a rather low screens definition (1366x768 with 96 dpi) and rather old-ish laptop, unlike some font designers that live in a filter bubble where everyone has the latest macbook. Thus, good and ..

TLDR Somehow my postgres installation was upgraded. When postgres is upgraded its data is NOT upgraded. This means postgres won't start BUT it will be a silent failure; you can only confirm this via the logs. tail -n 10 /usr/local/var/log/postgres.log The Long Version I went through a situation the other day where I would start and stop postgres and the database would NEVER be available for connection. Here is the error that I ke....

I use goodreads a lot because I like to read books and want to find more books to read. This morning I was reading a thread on hackernews on Sarah Manavis’s NewStatesman article and it reminds me of how much I want, I yearn, for useful book recommendations. I think about this pretty much every time I open the goodreads page or app and hope that maybe this is the day they finally fix recommendations, so I figure I would capture some id....

Today is September 11th. I remember waking up 19 years ago, coming into the living room, and my dad getting down on one knee so he was closer to my level. He told me that earlier that morning two airplanes had crashed into some tall buildings in New York City. I didn’t know what that meant at the time, but I soon found out. For several anniversaries thereafter, my elementary school class would spend a minute of silence in remembrance of t....

In the last article we set up pytest for a simple application that computes divisor sums $ \sigma(n)$ and tries to disprove the Riemann Hypothesis. In this post we’ll show how to extend the application as we add a database dependency. The database stores the computed sums so we can analyze them after our application finishes. As in the previous post, I’ll link to specific git commits in the final code repository to show how the project evol..

Some mathy-programmy people tell me they want to test their code, but struggle to get set up with a testing framework. I suspect it’s due to a mix of: There are too many choices with a blank slate. Making slightly wrong choices early on causes things to fail in unexpected ways. I suspect the same concerns apply to general project organization and architecture. Because Python is popular for mathy-programmies, I’ll build a Python project that..

Why is Python pulling in so many new programmers? Maybe some of that growth is from Python being a full-spectrum language. This week on the show we have Michael Kennedy, the host of the podcast "Talk Python to Me". Michael reflects on five years of podcasting about Python, and many of the changes he has seen in the Python landscape.

Go has a problem. Go modules place a strange naming requirement on modules version 2 or greater. Module names on modules v2+ must end in the major version ala …/v2, and communication of this rule has been weak. It's non-obvious, and the community at large does not understand it. I have seen many very large projects including Google owned projects get it wrong. I brought the issue up at my local Go meetup, and no one had ever heard ....

Last weekend I built a custom laptop tray design to fit my ThinkPad T480 laptop, my ergodox split keyboard, and my vertical mouse comfortably on my lap. We did 3 rounds of build/prototypes and I'm really happy with the one we have. Motivation and Context I have two main setups where I do my computing. I have a sit/stand desk in my office well-appointed with tented split keyboard, vertical mouse, laptop stand putting the screen at proper h....
