I was Youtubing this last weekend and ran down quite the rabbit hole. This all seems like mumbojumbo to me.

I could not derive a single piece of solid science in any of it.

It was remarkable how much content there was on this subject with little to no actual information - enjoy:

So, I decided to install Linux on my formerly-Windows-only laptop, and thought it was cool enough to go full time and ditch Windows completely. The downside was the lack of access to top tier games. No problem though, my plan was to take a break from gaming, figuring that by the time Linux had caught up with compatibility, computers would also be much more powerful and I'd be able to resume gaming at some point in th…

Let's hear your distro journey! What did you start with, what do you currently use?

The wonderful world of research paper identifiers. DOI (Digital Object Identifiers) are used by many modern research papers as sort of a UUID for papers, run by doi.org. But they're discipline-specific. So they're used widely by certain disciplines. But others use different databases. So for biology-related papers, NIH's PubMed ID. Or for Astronomers, Bibcode. All are "global" identifiers and each has some kind of co…

Doi is the main one. Most published papers and many other things have them. They're newer so often older things hang around too, I'd wager most new pubmed articles have dois too.

There are several registries, crossref is the big one in the west but it's not the only one. They have probably the best access to the data out of all of the larger registries though.

Dois are pretty good, though not persistent and there's no versioning built in so people have their own formats.

I spent a lot of time working with these as part of https://dimensions.ai for a decade or so. Happy to chat if you want to delve in more.

Chasing memory leaks in BCP [1] data load implementation in Babelfish [2]. Spotted unusually high RAM usage, decided to look deeper and got into a rabbit hole. Haven't had this fun of overnight debugging (of Postgres guts) for a long time. As a result found 4 different leaks and one (unlikely to be triggered) crash. And now have BCP data load impl with 100% constant-bounded RAM usage in a DB server process.

I did not realize that learning Fusion 360 was going to be such a huge chapter in my current journey. Looking back, I'm kind of stumped at how I avoided it as long as I did. I would now put learning CAD in the same category of mandatory life skill as learning to code. The ability to translate what you see in your mind to something that can be repeatably fabricated is an incredible power move, akin to learning how to…

If you don't know about Plasticity 3D, you should know about Plasticity 3D. It is different, but still parametric, and CADish.

For me, it's DIY audio. The thing about diy'ing audio (primarily speakers but also amps, DACs etc) is that you can get top of the line performance for a fraction of the market price. A $50,000 speaker setup that would bring tears to your eyes could be made for perhaps $5000. A DIY $500 kit can perform similar to a $2-3000 set of speakers. Open source amps with gerber files on github are amazing. The biggest reason it…

All that build up and not a link to be seen?!?! Where do I go to spend $ on a new hobby I didn't need?

Check out Hexabase on YouTube, and then check out DIYAudio.com. Those will whet your appetite, I hope.

All I want is a small stereo speaker to replace my awful monitor speakers. Like a small soundbar that doesn't suck. I might dive into this rabbit hole

Check out Hexabase on YT. He has really punchy small speakers that he has released designs for.
