We have near perfect processes for saltwater filtering.

You apparently understand less than me. The little I do understand is that CORS is protection for a site's user, not the site.

Every ad GET is doing a lot of things that violate that edict.

I don't understand it. And I'm a web developer. I don't understand the documentation, I don't understand the problem it's trying to solve and I don't understand how it's going about a solution of any problem. The closest I've come to an understanding is that it's meaningless make-work for a ledger of http calls that are not giving any security.

New comment by Beltiras in "Go ahead, self-host Postgres"

Beltiras — Sat, 20 Dec 2025 23:35:43 +0000

I've had my hair on fire because my app code shit the bed. I've never ever (throughout 15 years of using it in everything I do) had to even think about Postgres, and yes, I always set it up self-hosted. The only concern I've had is when I had to do migrations where I had to upgrade PG to fit with upgrades in the ORM database layer. Made for some interesting stepping-stone upgrades once in a while but mostly just careful sysadmining.

Given that you want to solve problems with a computer, what is the alternative to code?

Beltiras — Mon, 21 Apr 2025 16:16:24 +0000

Their trackrecord is such that if I got a similar call my first question when possible would be how I was being reimbursed. They are welcome to fork anything of mine if they observe the license attached. I will take a look at any PR. I will NOT spend time explaining anything to their engineers unless reimbursed at my regular rates.

Beltiras — Wed, 19 Feb 2025 11:58:35 +0000

Backblaze can lose 3/20 hard drives and still recover the data from parity drives. They don't have to rely on recovering it from non-operative drives unless they become unbelievably unlucky.

New comment by Beltiras in "The halting problem is decidable on a set of asymptotic probability one (2006)"

Beltiras — Mon, 29 May 2023 11:55:01 +0000

I had an insight when learning about the Halting Problem. There is a class of programs for which the Halting Problem is solvable since you can use circuit analysis to see if well-formed loops halt. We should strive to write programs in that class since then we know that the execution, long as it may be, will yield a result.

I found after starting to apply mise en place that when I wasn't doing it I was still quicker than before. I fetched more things from each cupboard or fridge when I opened them, even if I wasn't measuring out the item into a container beforehand.

Beltiras — Sat, 20 May 2023 06:33:36 +0000

I wonder if you could get the intended result for any language with a simple ruleset. You don't need a language to reduce/eliminate miscommunications, you need intent and understanding.

You have the right comparison. Developers need to remember that nobody had a job punching holes in cards after the revolution of personal computing. Going to be the same here. The jobs will revolve around operating the new "loom" which we have been given.

Difference is that compressive strength generally decreases over time. Here we have a product where it increases over time. Changes the equation on how you build and maintain it.

When I would have had to add another 2 batches of ~150,000 tokens.....

Beltiras — Mon, 08 May 2023 20:47:50 +0000

I'm working on something where I need to basically add on the order of 150,000 tokens into the knowledge base of an LLM. Finding out slowly I need to delve into training a whole ass LLM to do it. Sigh.

I can't convince them. Their belief precludes any sort of reason to pierce the veil.
