Compute differences between dates, times, durations and timezones
Underlying CLI and Go library: https://github.com/jftuga/DateTimeMate
They run Debian or Ubuntu great although I usually run them headless and just SSH into them. One experiment I did was with Talos / K8s with about 3 of these and it worked great.
* we had to resolve a variety of bottlenecks that appeared faster than expected from moving webhooks to a different backend (out of MySQL)
* * redesigning user session cache to redoing authentication and authorization flows to substantially reduce database load.
* we accelerated parts of migrating performance or scale sensitive code out of Ruby monolith into Go.
I'd like to know what database backend they migrated to. I was also surprised to read that the migration from Ruby to a more performant language had not already been completed. I assume this is because it a large code base with many moving parts, etc.
Swiss army knife CLI tool written in Swift using only native Apple frameworks.
The primary goal of this project is to demonstrate how many Apple standard library frameworks can be meaningfully used in a single, actually-useful CLI tool.

A performance comparison of four common Go string building methods.
___I recently updated my go-stats-calculator to include many more stats [2]:
CLI tool for computing statistics (mean, median, variance, std-dev, skewness, etc.) from files or standard input.
___I also created claude-image-renamer [3]:
AI-powered image renaming script that generates descriptive filenames for screenshots.

I'm sure there are a ton of other projects out there that do this, but I couldn't find one that fit my needs exactly, so I threw this together in a few hours.
claude-image-renamer uses Claude Code CLI to analyze screenshots and rename them to something actually usable. It combines OCR text extraction with Claude's vision capabilities, so instead of "Screenshot 2025-12-29 at 10.03.10 PM.png" you get something like "vscode_python_debug_settings.png".
A few things it does:
Handles those annoying macOS screenshot filenames with weird Unicode characters
Uses OCR to give Claude more context for better naming
Keeps filenames clean (lowercase, underscores, max 64 chars)
Handles naming conflicts automatically
If you're on macOS, you can also set this up as a Folder Action so screenshots get renamed automatically when they are saved to a folder, typically ~/Desktop. This is useful if you take a lot of screenshots and hate digging through "Screenshot 2025-12..." files later. MetalLB - https://metallb.io/ load balancer

Open to suggestions.About how long do these typically take to execute? Minute, Tens of Minutes, Hours?
My work if very iterative where the feedback loop is only a few minutes long.

I have these aliases, which are useful when piping output to them:
alias bd='bat -p -l diff'
alias bh='bat -p -l help'
alias bi='bat -p -l ini'
alias bj='bat -p -l json'
alias bl='bat -p -l log'
alias bm='bat -p -l man'
alias by='bat -p -l yml'https://gist.github.com/jftuga/2e4cf463dc0cdd9640c5f3da06b69...
* General Q&A
* Specific to programming - mostly Python and Go.
I forgot the command now, but I did run a command that allowed MacOS to allocate and use maybe 28 GB of RAM to the GPU for use with LLMs.
