Wow.. So I was trying to #optimize some Rust code that would take six hours to run.

My goal was to get that down to 3.5 hours (something I'd achieved previously with lost code). Some tweaking got it down to 5 hours estimated runtime.

Then I thought to do:

"cargo build --release" instead of just "cargo build" for the first time.

And we're down to 3 minutes.... not 3.5 hours... 3 minutes.

Ok.. Good to know. Debug adds just a tiny bit of overhead on some code ;-).

These guys were clever to an extent we no longer can imagine. They were constrained by resources at a point they had to dig into very clever tricks to do their thing.

I really have unlimited respect for the Unix guys, from the roots to just now, because they had to do wonders with machines that your phone or calculator would easily beat. (The same respect will apply to people sending other people to the Moon).

Current devs would just stop, cry, and extend their resources by purchasing the next tier of “subscription” for their infrastructure.

You don’t have unlimited resources. You will never. Resources you overuse comes from an artificial paradise abusing nature, energy and even abusing your fellow humans.

Just have a break and consider the word “optimization” : learn tricks from ancestors and consider using resource AFTER having put your optimization skills in practice.

Don’t use bloated frameworks
Choose the right tool for the right usage.
Do think before typing code.

Also, as a user :
- learn to enjoy simple things which does not necessarily involves cloud computing, you know the good old days of home computing with everything safe at home ? (Do backups)
- you might reconsider all the AI bullshit and buzzwords and use the brain you had since day one : such a device, when used correctly, can produce poems, do calculations, send people in space, draw, paint, write texts and even summarize them for you. It even might do it better than the LLM model next door, you know. It just takes some practice. Brain will have limited resources but you can also use clever tricks too (e.g. pencil to swap RAM to paper when needed)
- When people push over-complicated solutions, tell them and prefer others.
- Advocate the use of simple tools that does the job honestly, without bells and whistles.

We people, at either end of the spectrum may encourage people to have a fair use of computer resources.

Vulkan | 1000% / 4000% performance increase? What is this? :vulcan_hmn_r1:

Vulkan: a modern cross-platform API - great in Linux gaming too - seems there are many unnoticed crucial optimizations to be found.

Submitting 50 cmdbufs 1 time is more effective than sending 1 cmdbuf 50 times, right?

A tool for Vulkan operations (and benchmarking) is VKoverhead github.com/zmike/vkoverhead
