What web analytics tools y’all using these days?
Looking for:
- lightweight (fast loading)
- privacy centric: no creepiness, no ad tracking, just give me high level insights,
- GDPR friendly
- simple dashboards
- alerts of spikes
- not too expensive to run on many sites (doesn’t have to be free)

SaaS builders: which libraries/frameworks are you using to interact with LLMs?
How are you dealing with LLM costs? Is it a problem?

A car commute is the perfect amount of time to build and ship ideas. I just gotta keep my eyes on the road.
Looking for a fully voice controlled AI coding tool, ideally works on phone.
What tools can help me do this? Or do I need to vibe code it myself (while not driving!)

Experimenting with something like this for @compiler-explorer.com - wondering what your thoughts are? AI is getting everywhere, and can be divisive. I'm hoping something like this - so long as I can get the output quality high enough - is a net benefit to help folks learn more about their code.

Ergo mech portable setup… 3 modes:
1. Full: best ergonomics. Takes about 20 seconds to setup.
2: Quick: busting out laptop quickly. Takes about 5 seconds.
3: Tiny: works on lap, plane tray, etc.

We’ll know we’ve reached AGI when we see models that can figure out the naming convention of models.

What happens when LLMs train on code that's popular but wrong? zdimension.fr/everyone-get... explores this, with interactive diagrams exploring the error
Everyone gets bidirectional BFS wrong
People really need to stop blindly copying code from the Internet.

Looking at a decade of GitHub stars on one of my projects.
It hit Hacker News front page twice. Pretty obvious when.
But aside from that, it shows steady and remarkably constant organic growth. I have no idea how, and I'd like to learn more.
How do you discover new projects?

I just built a hybrid 16-bit MS-DOS/32-bit Windows executable by hand in NASM so that both parts could share common data sections. To fully conform to the PE specs (which I prefer, for long-term compatibility), the file size must be rounded up to the nearest 512 bytes. So I had some space left over…

Oh wow… I just stumbled across @hofferth.net, who’s designed many many many many exciting Mac Mini enclosures!
The "Mac mini Pro" Version 2 is now available! Easier and faster to print with only minimal supports required. Better-suited to 2-color printing of the Apple logo. Left- and right-handed options now available!
Thanks for sharing and enjoy!
