mareko | 5 days ago | on: I'm losing the SEO battle for my own open source project
UDRP disputes become straightforward when you can show the other party registered a domain using your mark in bad faith. It won't fix the Google ranking overnight, but it gives you real legal teeth beyond just SEO whack-a-mole.

This is possible today with complete privacy for people with biometric IDs and biometric passports (ie most passports, EU IDs, Aadhaar IDs, and more) using a service like self.xyz
mareko | 7 months ago | on: Optimizing my sleep around Claude usage limits
A while back, I had a big paper deadline a week away and knew I didn’t have enough time to finish without sacrificing sleep.
Rather than cutting my sleep short, I decided to stick with 7–8 hours of rest and instead lengthen my wake window. I worked out a schedule that gave me six nights of sleep across seven days. It meant waking up at stranger and stranger times as the week went on, and getting some odd looks from my roommates when I emerged from my room. But in the end, it was totally worth it. I was waking up well-rested and ready to tackle those extra-long days.
The effort paid off 100%. Not only did I make the deadline, but my paper was accepted as well. A year later, that same paper helped me get into my PhD program of choice.
It’s funny how these short bursts of intense effort can sometimes have such a big impact.
Best of luck with your side hustle!

I wonder whether it's possible to achieve similar performance but with a simpler design that uses scalable reader-writer locks. They can be made a lot more efficient than what's commonly out there using the C-SNZI lock-free data structure:

mareko | 1 year ago | on: So you think you want to write a deterministic hypervisor?
If anyone's interested, here's a publication that talks about it in more detail:
https://dspace.mit.edu/handle/1721.1/72082
The use of performance counters here also reminds me of another project I worked on called Kendo, which was a posix thread like replacement that used performance counters to enforce a deterministic interleaving of synchronization operations (mutexes, etc). The system could guarantee determinism for programs that didn't have race conditions. Back then, I found that counting instructions wasn't deterministic on the processors of the time, but counting store operations was. If anyone's interested in that work, here's the publication:

Spoiler alert: they can't be used to replace your smartphone's camera lenses yet, but can be used for IR distance sensors used on drones and soon, polarization sensors that will be able to tell materials apart and even detect cracks in concrete.

We can do a poll to confirm this without revealing your phone preference.
Just respond with "Affirmative" if you are an iPhone user and dont like this OR you're an Android users and like this. Likewise, respond with "Negative" if you're in the opposite camp.

Does this only work on existing codebases?
