Last night I went to DigitalOcean and spun up a tiny new, $4/month droplet – on my own dime! It sounds crazy, but I’ve never actually wanted to pay for hosting myself before. But I have a fun little web app cooking up, one that might eventually pay that $4/month back with interests, and I decided, why not, it’s time to finally put some of my own skin in the game with this whole sysadmin thing....
Epistemic status: Very unclear, also I Am Not A Lawyer This Is Not Legal Advice Get Off My Lawn (N.B.: I"m using “GPL” with broad strokes here, to point at “open source licenses it’s straightforward to run afoul of”.) Policing is always hard in a world of limited resources. Especially when one is targeting sophisticated, well-monied criminal organizations, it can take an awful lot of time and effort merely to credibly reveal that wrongdoing has taken place....
What’s the best way to get a job? Show someone with a job to do that you can do the job within their iron triangle. What’s the best way you can show someone you can handle a complicated k8s deployment, with 7 different CNCF-approved add-ons, zero-downtime rollouts and a whole bunch of YAML files? Probably by competently and publicly running your own complicated k8s infrastructure. Self-hosters remind me a lot of the sysadmins of yore, who mostly ended up in the profession because they just couldn’t help but mess around with their underlying computing machine until they knew all kinds of weird nooks and crannies within it....
If you’ve been following my posts recently, you might have noticed that I’ve been working more and more with PHP lately. As someone who was curiously allergic to web dev as a teenager, it has been a strangely healing experience for me. I’d like to say it’s because my experiments with Laravel, the only OSS work of which I can point to is testing the Homestead VM’s compatibility for Shell Bling Ubuntu, convinced me....
PHP is, for better and for worse, the Python of web dev in my eyes. It is exceptionally easy to get started, in a way which I think younger developers may not be fully aware of. So here I’d like to make them aware of it! That’s right, this is a Slowstart for people who have never touched PHP or web dev before. Start the way we usually do on this blog, with the “tutorial-in-a-box” by installing Vagrant and Virtualbox so you can create a disposable virtual machine with just a few commands....
First get a working script. “Hey GPT-4, write me a ChatGPT script that does .” Manually check over the script and iterate until it’s giving me what I want. “Now wrap the script into a click command-line interface.” I almost always specify to use an --input flag and an --output flag. If the data it’s working with is human-readable, “Make it so that if --input is not specified, it reads data from stdin....
It would have to be finstem, a simple command-line program I wrote to reduce Finnish words down to their root form. Finnish is a lot like Latin or Russian in that its words often become lumbering behemoths of rewritten consonants, suffixes upon suffixes, and this makes it hard to look up in a dictionary – that is, until you factor in its very regular orthography and the phenomenal efforts of the Finnish programming industry: finstem is basically a very specialized UI for the OpenOffice spell checker, and I have no shame in admitting that....
(Inspired by yungporko’s Ask HN post, which got me thinking.) Pretty much every community, dojo, workplace, subculture, scene you can imagine in the modern day had a software sub-scene embedded within it. It can be as small as “that guy who does our Excel”, or as large as the scene itself . This is owing to the fantastic generality of software as a way to make almost anything more efficient, but we won’t go on that tangent now....
Poking around in a fresh VM in Vagrant, I see bash dash, a POSIX compliant shell linked under sh python3, 3.11.2 at the time of writing awk, specifically mawk sed, if you count that (I do) perl, specifically Perl 5 There may be others I missed. Why I’m curious: Knowing that a language is installed by default on the most popular Linux distribution can simplify certain concerns considerably, which are of special interest to people who don’t work on Internet-connected boxes....
