New on Hacking SaaS - All About UUIDs: open.substack.com/pub/hackingsaa… With contributions from Andrew Atkinson Lucas Stephens Lalit Pagaria Vlad Mihalcea Rauan Mayemir Stephan Garland Jeremy Schneider and Ricardo B�nffy - I love the cycle of learning and sharing that the SaaS Developer community got

PSA: If you have / mounted over NFS because you thought exposing ZFS as a block device for your VMs was a good idea and then expanded that thought to include /, ext4 will get big mad if you make the block device go away while it's running.

I spent a couple of hours trying to get ceph-csi-rbd to create a PV for me this morning. Failed with logs about the PVC having another operation. No such PVC existed. No pod failures. Ceph shows no volume was created or attempted. Wheeeee abstractions are fun.

I’ve successfully re-capped the PSU for my (3rd, hopefully final) Laserdisc player, and added an RF tap. It’s a Pioneer LD-V4400, if you’re curious. Here’s hoping the SNR on this one is good enough for ld-decode [0]. [0]: github.com/happycube/ld-d…

I figured out a work-around to [mostly] automating Venmo payments without an API. 1. Create a payment link (venmo.com/paymentlinks/) for whomever you want, with an amount. 2. Have Zapier send you that link on a cron (Schedule) over SMS, which will open in Venmo. Tap confirm.

Every time I use ChatGPT (-4, I’m not a plebe) for anything mildly complex, it consistently fails. Most recently was implementing Fisher-Yates (Durstenfeld) in C. I am not a C coder, but can muddle my way through. ChatGPT got hung up on pointers, and I mean, fair. Still.

In an attempt to keep Ansible tasks Ansible-native, I created a horrifying monstrosity to find the last numbered file’s index in /etc/apt.preferences.d/. Not really sure if this is better than just shelling out to ls -1 | sort | cut, but ansible-lint doesn’t complain soooo

Ever wished you could merge the frustration of YAML with the fun of functional programming? Yeah, neither have I. github.com/yaml/yamlscript

JAVASCRIPT was not intended to write anything besides FRONTEND NODEJS IS A MISTAKE TYPESCRIPT IS COPE (YOUR LANGUAGE ISNT REAL) GET THE FUCK OUT OF HERE!!!

"Write a proof of concept first," they said. "K.I.S.S.," they said. Now I have a proof of concept that isn't extensible, so I have to rewrite it to actually use it. I think I'm a lot better at writing small functions to do one thing extremely quickly than I am connecting them.

Gonna eventually do a deep-dive write up (not here), but tl;dr I figured out why UUID generation is so much faster on MacOS compared to Linux. I mean yeah the CPU helps, but it’s the native library’s use of arc4random that really makes it fast. gist.github.com/stephanGarland…

Me writing small C shared libraries for my Python project: haha yes this rocks, witness the speed. Me observing RSS usage: no wait this sucks WTF.

I mean this in the kindest way possible: fuck the Python GIL. It has caused me to spend countless nights poring over malloc documentation and running endless valgrind, massif, and memray tests, only to discover the cause of my memory bloat was from the GIL not being released.

I simultaneously want to and do not want to find out why large loop performance (and apparently other things) has been steadily declining in Python since 3.11. I also have a sinking feeling that it's not going to be fixed, and I'll be stuck at 3.11. github.com/python/cpython…
