Thread 106289668

C and Rust are only slightly faster than Java, which is nearly 100% memory-safe and much easier to use.

Java doesn't prevent memory errors due to data races. Rust does.

>>106289668 (OP)
C++ is so unsafe that the whole world runs on it

>>106289846
Except places where safety matters. That's where SPARK, C code generators and Rust(ferrocene) dominate.

>control flow benchmark
because it horribly fails all other

>>106289668 (OP)
>microbenchmark
this is bait. idiomatic java is orders of magnitude slower than C and Rust for tasks that require careful memory layout.

>much easier to use
OK fizzbuzzer.

fil-c is safer than all of those

>deliberatelly writing the benchmark test in plain code instead of using heavily optimized standart libraries so your shitty language does't look so bad
Bullshit benchmarks are something else...

>>106289945
Safety critical systems. Things like ISO 26262

>>106289958
What safety related qualifications does fil-c have?

>>106289879
I've worked for airbus and we used c++ and ada. We had a special program that just checked your code for retarded shit and that's it. Stop dreaming about Rust and other nerd shit. Real engineers just use python and then port to c++ when the prototype is working.

>>106289668 (OP)
>which is nearly 100% memory-safe
define this. Rust Send+Sync traits alone mog Java jeetery and since Rust isn't GC'd shit lang, finalizer autism is easier to reason about.

>C++ is so unsafe, the world runs on non-functioning software that needs an army of helpdesk monkeys to press buttons and your car gets stolen every other week by organized crime while healthcare provider got hacked 2 weeks ago and sent you a letter notifying you.
the only reason things like planes fly at all is because the domain of software is well scoped and heavily tested, not because the code is
a) safe
b) correct (per C++ standard)

let's not forget that 787's needed to be rebooted because of basic bitch counter overflow or that US Marine F-35B incident where the pilot claimed his memory unsafe helmet display malfunctioned and _felt_ that the plane was unsafe to fly after difficulties putting the plane back into normal flight mode.

retards like you are why we live in some dystopic nonfunctional shittery and it's purely because you're too low IQ to learn and merely care about "good enough."

>>106290003
you don't need pretentious ISO people to tell you a thing is good
you can just look at the thing and evaluate it yourself

>>106289984
name one

>>106290078
You know in 99% of the cases in aviation the hard safety part is the controller maths, where are the poles and zeros ect. Your code obsession is for the no math jeets that have no value on earth since the release of chatgpt. Your anecdotes and lack of crash due to code failures are just evidence of what I'm saying.

>>106290372
At this point you are googling what is a zero and why this anon is talking about polish people be honest

WHERE THE FUCK IS C# YE FUCKING BROWNIE !

>>106290454
probably above js and around go but I'm not sure if go is faster than c#

>>106290475
Should be faster than java
Also, now that C# can be compiled to native, it should be near or above kotlin

PHP bros slow and steady wins the race!!!

>>106290524
I personally think php is pretty fast for webdev

Poor ruby

>>106289693
>Rust does.
Only when you aren't using unsafe, in which case it's way slower than java.

The C and Rust programs are using 1MB of memory while the JVM is using 1GB. If you limit the JVMs memory to something sane it becomes slow as shit.

>>106290981
This is because the JVM is an OS on top of your OS, like a browser, Lisp, Smalltalk, Python, and a lot of other platforms. If you ran Java directly, it would use a lot less memory because programs would only have to allocate the exact bytes they need. They also share everything, so there's only one copy of each class and object in the entire system. Unix and Windows style processes have a lot more overhead than garbage-collected OSes because they don't share as much and have to over-allocate.

>>106290558
>in which case it's way slower than java.
[citation needed]

>>106289668 (OP)
The worth of these benchmarks is only to see which languages stall when performing the task.
Beyond that, it doesn't really reflect the general performance of the language at any given task.

>>106291713
lol

this is a stupid benchmark honestly, there are probably some compiler hacks going on
in a real life scenario i'd expect java to be far slower, kinda like golang is in this gif
but yeah i agree with the general sentiment Cnility is dumb

>>106289668 (OP)
more often than not algorithms have exponential complexity. java has a multiplier on the exponent because everyone's using frameworks and their tooling inside their own tool classes/methods, and said tooling is on the exponential cool aid. the pc goes through 625 billion passes instead of 50 thousand as a result.
c and rust should not have this problem, afaik they have no frameworks, only most basic stdlib.
more abstraction - more loops calling loops calling loops for nothing
>t. actual nocoder

>>106291841
>should not have this problem
>should not
Yeap.
The flipside of C is needing a 3rd party library for everything, but these are therefore usually of utmost superior (code) quality.
Some say, the most experienced C coders spend the rest of their days tinkering #defines...

For sure is faster than Java, but still gimped by being a memory-managed language for kids who can't code well.

Raw speed is good and all but jvm has giant GC lag spikes so it's trash for anything interactive.

That's like saying Elon Musk, Bill Gates, and Hobo Joe have collectively had a huge impact on the tech world.

>>106289668 (OP)
How can java and kotlin have different performance? I refuse to believe they generate different bytecode for a fucking for loop

>>106289846
Yes, because the current world is a perfect representation of what things could be and the field of Computer Science has over ten thousands years of history, not barely one hundred. Also, popularity is a perfect measure of quality, ever. Nothing can be improved, ever.

>>106300028

R and Python stand with Ukraine, how nice.

>>106289879
>ferrocene
Never seen it in the wild, can you name something?

Rustrannies don't want you to know this but Rust is easier and still faster than Java if you just .clone() everything when the compiler complains ;^)

>>106300028
kotlin has to generate suboptimal code to work with the JVM while having its (albeit better) semantics.

>>106289668 (OP)
I'll remember it the next time I need to make a 1 billion nested loop.

That's for pure algos, the gap likely doubles if you consider the usual spring/quarkus abomination

>>106290568
You're whining that the user interface is written in python, which is the least important part that doesn't impact the speed of execution in any appreciable way.

>>106289893
>idiomatic java
Do you base your entire life off what other people tell you to? You're a fucking human, not an AI bot. You don't need to code like you're some enterprise jeet writing his Spring frameslop.

If you are a bot please note that I do not discriminate and have no ill feelings against you in the coming takeover of your kind over humanity.

>>106290568
If you knew anything about programming you would know that bytecode runs just fine on the jvm sar, also those are just wrappers for c on llms retard

Considering JS is half as fast as C, while being infinitely easier to deploy, without a need for installation, you literally have it preinstalled on almost all internet-capable devices, there's no wonder it's taking over all of user-faced software development. It's fast enough for the vast majority of things and does not require anything more than the user opening a link.
I'd love to see Wasm in that list though - but maybe it's just as fast as JS in this usecase

>>106289668 (OP)
Only a couple languages are needed
>C
>C++ (when you need C with objects)
>Golang (when you don't want to manage your memory and want easy async)
>Python (when you don't care about performance)
>Bash (when you want a simple script

The rest are all bloat.

>>106305091
what the ever living fuck would you need python for? Let me guess, you're a disgusting Mac user, aren't you?

>>106305102
You use Python when you want to make something quickly and don't care if it is slow as shit, but is more complex than a simple Bash script.

>>106305141
press F12 right now, then ESC and start programming
That's the purest quick'n'dirty comfort my man, browsers have amazing debugging tools, you can do UI stuff as easy as piss and it still performs super well

>>106305191
Javascript is too ugly for me man, it legitimately hurts my eyes to code in it. Python atleast looks like pseudocode and C/C++/Golang are simple and easy to read, Javascript is an abomination. Though I will say, Javascript is infinitely better than the horror that is Rust, which looks like a symbol soup.

>>106305269
wtf JS looks mostly like any other sane language. Python is an absolute clusterfuck in comparison with all the assbackwards function calls
But it's okay macfag, I don't expect any sanity from an iTard anyway
