I love shell scripts because they’re so pragmatic and often allow me to get jobs done really quickly.

But sadly they’re full of pitfalls. Pitfalls everywhere you look.

Today, a coworker – who’s highly skilled, not a newbie by any means – ran into this:

$ bash -c 'set -u; foo=bar; if [[ "$foo" -eq "bar" ]]; then echo it matches; fi'
bash: line 1: bar: unbound variable

Why’s that happening? I know the answer. Do you? 😂

Stuff like that made me stop using shell scripts at work, unless they’re just 4 or 5 lines of absolutely trivial code. It’s now Python instead, even though the code is often much longer and clunkier, but at least people will understand it more easily and not trip over it when they make a tiny change.

If some of you budding fathers want to know how I created a computer nerd to one day work for Facebook in the big USA, well you purchase a $1000 Xmas present, an enormous thick book with C++ programming, and say, you can play as many games as you like kids, but James has to create them using computer software.

SO James created once a 3D chess program with sound, took 6 months or so, really hard to beat, not based on logic moves point by point like other chess programs, this one was based on the depth of looking for patterns, set it to 5 moves ahead and you were toast every time. Nice program too, sadly gone over the years, computers suffer from bit rot. We used to try and mark rotten hard drive discs once as bad sectors, not sure how UBuntu does this these days, I see a dozen errors on the screen every time I load.

Today I would purchase for my kids AI CAD simulation software with metal 3D printer and get your child to build fancy 3D models and engines from scratch. This will make them an expert in the CAD AI industry by the time they are 14 years old. Sadly AI is here to stay and will spoil the Internet.

↳ In-reply-to » Hack of the day: running watch -n 60 rm -rf /tmp/yarn-avatar-* in a tmux because all of a sudden, without warning, yarnd started throwing hundreds of gigabytes of files with names like yarn-avatar-62582554 into /tmp, which filled up the entire disk and started crashing other services.

We also rented a cabin for 5 days, and did a lot of things..

We visited Heddal stave church from 13th century, was really nice. Never been inside it until yesterday. Such a great building. Amazing to sit there and think about all the people who had been there since it was built.

Pinellas County - Long Run: 10.19 miles, 00:09:43 average pace, 01:39:03 duration
practicing 3 minutes running and one minute walking. not only for the knee but also for the PTC (~46.6 miles) coming in about 17 weeks. the knee actually hurt a little the first 5 miles but afterwards nothing. not sure if i finally found my stride but it felt great once the dull pain was gone.

↳ In-reply-to » @bender I don't mind the character limit. If I hit it and I still have more to say, it's a good reminder that I should probably write a note instead. I like to POSSE anything that might have value outside of the current conversation.

@mckinley@twtxt.net, in your blog, I think a “line-heigh” of 1.5 (if I remember correctly you are setting it on the “body” on CSS) will make it more legible.

Pinellas County - Easy: 5.05 miles, 00:09:08 average pace, 00:46:08 duration
everything clicked today. kept a steady but mildly progressive pace whilst keeping the heart rate in zone 2 for the most part. nothing felt strained and breathing was easy. this one was a great boost in confidence seeing the progress made in the training and very happy with it.
