[@Felice_Enellen]

@@anonymous_246 Oh, the binary contents of memory at that timestamp represent the ASCII text, "HELP". I figure this is just a variation on the famous fortune cookie note that says, "Help! I’m being held prisoner in a fortune cookie factory!" Any time you see binary in 8-bit blocks (in this case formatted with the 0b prefixes some programming languages use to differentiate binary from decimal) where the first two bits of every octet are almost always 01, you can guess that it's ASCII. There are multiple online decoders if you don't know how to do it in your head.

[@realityveil6151]

In my long years of experience in the field I have learned the hard lesson that just because someone did an amazing passion project doesn't mean they'll be a good engineer. There are motivation issues, and they tend to be mavericks and lone wolves. And they just suck in general. Guys who pour all their heart and soul into a terraria computer can barely bring themselves to open an industry standard circuit design tool and actually do work that someone else has assigned them. This is because they're all motivation and passion and no discipline and focus. If they ever get around to finally producing anything at all they produce shoddy, sub-standard, piss-poor implementations because they learned on the fly and did not persue classical training, on top of being unmotivated and just trying to do the minimum of work. In nearly every case, my more level-headed, dedicated, classically trained engineers have to fix everything before the product could ship. Often that fixing process takes longer than if my real engineers had just ran the project right in the first place. So no, I will not be hiring this kid or anyone like him. They can stay in youtube land while the real engineers with dedication, discipline, heart, and real world training do the actual work.

I don't play Terraria and don't program, but as an onlooker who enjoys seeing what people can program, his work is impressive. Would be good to see people keep adding: build another Terraria inside the game and another pong game inside that!

Comp sci student here, this is absolutely incredible! Relogic is missing out if they dont pay you to bring your wiring optimisations to the base game

[@noaag]

"developer hire this man" is usually like totally unrealistic but i'll make an exception (ha-ha "exception"), this is amazing, re-logic hire this man

[@benbrook469]

they probably wouldn't be able to offer a high enough salary

[@julealgon]

The optimization he did is very basic: he just introduced a cache to store wiring sources and targets. While the whole thing is very impressive (including the fact that he created his own mod), it would not make sense for any developer to hire the guy just because of this very trivial optimization alone. Also, it is likely that this wasn't done in the original game because it just wasn't needed: the original game was not necessarily designed for very long and many wiring connections in the first place, because that wasn't the whole point of the game, it was just a minor aspect of it all things considered. Optimizations are usually done after measurements show that a given area is a problem/ bottleneck, and in this case it really isn't for "normal" play.

[@benbrook469]

@@julealgon ok but this is a better signal than anything you could uncover in a few interviews

[@julealgon]

@benbrook469 Sure, it shows practical experience, which is a good sign indeed. I'm just saying it is still a fairly simple optimization that most candidates should already be aware of.

[@Zei33]

I really enjoyed how you rewrote the wire system. Makes total sense and it's amazing that the original devs never thought about optimising it in such a way.

In real-world digital logic, these gates exist! They're called transmission gates. They have applications (mainly multiplexers iirc), but since they don't amplify their output like inverters do, they aren't found on their own.

[@Shugas.Kitchen]

The fact that you continued after it didn’t work and found that one wire that wasn’t right and debugged the whole thing is what sets you apart from most ppl. Others would have just quit. Bravo 👏🏼 well done 👍

[@LoblueHaze]

This guy uploads a first video to his channel, designs a gate for the CPU, engineers and optimizes the algorithm for the CPU, develops a mod to massively speed up the wire mechanics for Terraria, and, most importantly, uses Rust. Your work is marvelous, please keep up the good work!

"The game engine is too slow so I made it better" is literally what made Factorio the top 3 game on Steam at launch. The devlogs going into bit level optimisations just to get a little bit more performance was insane (I started playing back when belts moved physical objects and 1k SPM was a dream, now that's the starting point for an end game base).

Wow this is insane man. Reminds me of those old videos of people building computers in minecraft but this is even more difficult since you're limited to two dimensions. And then to put all your work into a well made and succinct video? Really good stuff dude!
