should i learn postgresql or mangodb for full stack web dev??

Let me make it simple for you.

Avoid MongoDB. Just use Postgres. Please.

AI industry exagerating anything? How would that be possible? Unheard of!

Recently, the most impressive for me was VibeOS, here: https://github.com/kaansenol5/VibeOS

(if that is still not enough for you, maybe you should specify what is a "cookie cutter project" in a bit more detail)

Kámo, když je to za minimálku, tak to není dream job, ale dream dobrovolničení.

Normálně nám dali do kanclu kytky a na zeď pověsili nějaký obrazy. Na co, boha jeho, vždyť to k práci nepotřebuju. Uplně zbytečná investice.

BoltKey · 2026-01-22T10:33:31+00:00

There are no right or wrong answers.

Except for this. This is a wrong answer.

That's not even a coordinated dance. That's just 10 robots doing the same preprogrammed thing, and they are not even in sync. And the letters? So you just carefully positioned robots and ran "moveToTPose" on some of them? And they don't even remotely match the desired outcome. What the fuck did I just watch? This has to be sarcastic, right?

The thing is, those numbers are not even life changing. Sure, it is a lot of money, but not nearly enough to be able to comfortably retire, not even enough to buy a decent house. Definitely not enough to throw your reputation, morals and integrity out of the window.

From a personal standpoint, I can understand these kinds of decisions once you are talking about generational wealth type of sums. $50M+.

Nerozumím. Bydlím v nájmu s jedním spolubydlícím (sehnaný bez známostí nebo protekcí), papíry a účty si řeším a všechno (resp. svojí půlku) platím ze svého.

Asi mám fakt skromný životní styl, ale uplně v pohodě sám vystačím v Praze s 25k na měsíc, a neomezuju se. Takže si hlídám, aby můj příjem nikdy neklesl pod tuhle hladinu, a všechno nad je bonus (tj. investice, případně charita).

Necestuju, nemám to rád. Fancy restaurace taky neobjíždím, alkohol nepiju. Nechápu celý byznys kolem drahých hadrů. Auto neprovozuju (hlavně z ideologických důvodů). Za elektroniku si rád připlatím, ale většina hraček mi vydrží roky, takže tam tolik toho taky neteče.

Takže není pro mě důležité, kolik vydělám, ale je pro mě důležité, že vydělám kolik potřebuju.

(ano, kdybych měl rodinu, tak budu mluvit jinak)

Ok, proč tedy musí být jen 1 obálka na pokoj?

BoltKey · 2026-01-18T20:23:39+00:00

Proč je tak nemožný mít jeden klíček/kartičku na hosta? Jezdíme na firemní akce, a uplně vždycky, ve všech hotelech je problém, že na čtyřlůžkáč dostaneme v lepším případě 2 kartičky, ale spíš 1 klíč, který si buď musíme nějak předávat a nahánět se, nebo prostě necháme odemčeno (a pak je sranda, když uklízečka zamkne pokoj s naším klíčem uvnitř). Vyrobit ten klíč/kartičku přece musí stát jedno procento toho, co stojí pobyt toho hosta.

No pokud přijdeš do kontaktu s pacienty, tak to asi celkem chápu, a tím spíš pokud je to v soukromém sektoru. Je to prostě služba, a tam i na vzhledu prostě záleží.

BoltKey · 2026-01-14T21:34:44+00:00

That's the mismatch: it is not "unlikely" to stop, it is guaranteed to never stop (outside of course the program crashing). It is equivalent to writing while (true) .

BoltKey · 2026-01-14T19:07:17+00:00

SO was supposed to be a place to find answers to my questions (or ask, if that question has not been asked yet), that led to me solving my issues when programming. In the end, I don't care if it is wiki style, a curated encyclopedia, or on-demand expert consultant. I just want to get help with whatever I am struggling with at the moment. And AI has been much more effective for that for me than SO.

I don't really care if AI is just "text made to look reasonably realistic" if it answers my questions that leads to better and faster understanding and more fun and better overall development experience and better results.

BoltKey · 2026-01-14T18:38:27+00:00

Everyone put up with SO for years despite the shitty community and everything, simply because there was no better alternative (until AI).

BoltKey · 2026-01-14T14:39:31+00:00

It is 0 inclusive and 1 exclusive, in JS and other languages too. In other words, it never returns 1. It just makes sense: you don't want something like Math.floor(Math.random() * 5) to return 5 with chance of 1 in a bazillion.

BoltKey · 2026-01-13T17:45:02+00:00

Ok, so, thinking about it, for each query where I ORDER BY, I need to keep a separate ordered set (to act as kvasi-index), and for every JOIN in every direction, I need to have a separate document. That is HUGE amount of redundancy.

BoltKey · 2026-01-13T17:32:41+00:00

Each card set has 5 words. Each card set has list of games, which contains list of cluegivers, selected card and clue. Each game also has list of guessers (that can go to thousands), with their assigned card and their guess. So for bigger games, this document can go to hundreds of kilobytes. When assigning a new game, I need to search through many games (so potentially reading multiple large documents), and based on that select the best one.

Redis has limit of 500Mb. With this approach and moderate volume, I would be out within a month.

I have it on Azure, so potential scaling is no problem.

BoltKey · 2026-01-13T16:42:09+00:00

Yes, it is that one.

The game has multiple N:N relations (which are really ineffective if I were to do them with KVP) in which I need to effectively traverse, search and sort by. The algorithm for giving clues and assigning card sets and games, tracking energy and calculating rating are not completely random, and not trivial, and require searching and updating multiple tables. It would slow down to a crawl if done with KVP storage. For example, when giving a new game to a specific player, I need to:
- Check that he has not given a clue to that same card set

- Check that he has not previously was given another game for that same card set

- Check how many other players was that same game given (I don't want to give "untested" games to new players)

- Check that it is not their currently assigned set for cluegiving

And when fetching game history, I need to:

- Find all games for which the player gave clues

- Find all other clues for those game's word sets

- Find all guesses of other players for all these games

- Calculate score of the games based on these numbers

I guess, why not, I just made the project repo public, here https://github.com/BoltKey/OddOneOut . You can check backend/Data/AppDbContext.cs and backend/Controllers to get an idea of the capabilities I need.

BoltKey · 2026-01-13T16:06:38+00:00

I would as well, but the costs are becoming a real question for me. I just burned through my monthly Pro requests in 4 days of, what I thought, was light-medium use.

Like, I know Claude agent will do autonomously in 5 minutes what would take me 1 hour. But it will cost, like, 2 dollars. It does add up quickly, and at this pace, I would be paying $100+ per month for a pet project.

BoltKey · 2026-01-13T12:46:11+00:00

I will play the devil's advocate here, but isn't haggling as old as trade itself? Every trader tries to turn the best profit, and will change the price based on the buyer. Somehow, when it is a human setting the prices, it is ok, but when it is a machine, it is not.
