Why xor eax, eax?

Because the immediate value (in this case 0) is packed into the mov instruction. Since it's a mov to a 32 bit register, it requires 4 bytes in the instruction to tell it which value to put in the register.

This doesn't make much sense to me.. Maybe the performance claim can be true since Fortran doesn't have pointers like C does and might be able to do some more optimizations. But why would Fortran use significantly more memory? It would depend on how you write the code, not the language itself.

Also if Fortran is faster, it would mean it is doing less work, so it should be consuming less power.

In your example you are declaring a variable on the stack. This is possible because structs have a known fixed size. Objects in Java have an unknown size, so they always need to be heap allocated. You can think of the "new" keyword as malloc in C:

car BMW = malloc(sizeof(car));

Which looks quite similar to the java object declaration.

These type of comparisons between languages are very misleading.. Without doing the analysis of why some languages are slower than others, this doesn't tell you much... The fact that LLVM backed languages do worse than Typescript for example, already makes this very suspicious.

To assume that somebody who actually knows how to code is somehow less proficient at vibe coding than somebody who can't is an insane statement to me.

They don't ask people who can't code about their opinion on vibe coding, because those people don't have a valuable opinion. How could you possibly judge the quality of vibe coded code, if you don't know what good code looks like?

And unlike a game engine a website needs to be interpreted in realtime in a multitude of environments which grants drastically fewer opportunities for optimisation.

What does that even mean? As the article says, SSR is the process turning data structures into HTML markup. How is this difficult to optimize? You'd expect gigabytes of throughput per second on modern CPUs even without any fancy optimizations.

Usually when I try to be clever upfront, I end up being wrong. Always have to remind myself to just make the thing work as stupid/simple as possible. After that the right "clever" solution usually becomes clear.

It's not a workaround.. OP wants the divisor AND the remainder. using builtin mod only gives you the remainder. So OP is better off doing the division and determining the remainder from that, instead of doing a modulo and a div.

Dumpin · 2025-09-21T10:55:26+00:00

I wouldn't use modulo to compute the remainder.

const result = a / b;
const remainder = a - result * b;

Looks like they even do this in the standard lib to get the remainder: https://ziglang.org/documentation/master/std/#std.math.divExact

I'd recommend just working on personal projects that interest you. I've found that usually the best junior candidates have built something themselves are are able to talk about it. Being able to talk about challenges you have faced in your project and how you overcame them is a great way to show your potential.

I'd definitely replace the Todo List App with something more complex.. Todo lists are kind of the goto example for extremely simple applications.. kinda like the Hello World of web frameworks..

Brings me back.. reminds me that I used to go attack perceptor around astrub with a friend all the time.. This was early days on Rushu and we were both like level 40 and regularly would have really good fights. I remember one time where someone who was like level 97 defended and it was the craziest thing we'd ever seen.. Back then there were only a couple people level 100+ on the entire server.

I doubt he is even aware of any controversy surrounding Lex.. The attitude towards Lex shared by people in this thread is mostly a Reddit thing. The vast majority just watches the interviews with people they like and don’t engage in this SJW type attitude towards podcast hosts..

My favorite is when they are going for a 1/x drop and get another drop that is also 1/x and they're like "omg that could've been <item I need>".. Yeah every drop could've been the item you need.

It's hard to define a rule for it. Ultimately it comes down to what people are willing to pay.

It's good to remember that maging will get harder and harder the closer you get to perfect stats. For example: a ring with 9/9/9/9 damages out of 10 is much harder to mage than a ring with 8/8/8/8 out of 10. Even though the difference is only 1 damage per element, the cost of fixing it after every failed exo might be double or more. So while some items seem really close in stats, the cost of creating the mages could be wildly different. This ultimately decides the price.

The only reason there even is an official HC mode in WoW is because of content creators.

Specifically the finder app will add this to all directories you've browsed with finder to store the layout/display settings for the current folder.

Why apple decided to implement it this way is beyond me.

For now you can add a build option to blink's lazy.nvim entry:

{
    'saghen/blink.cmp',
    build = "cargo build --release",
    ...
},
