There's not even a chance to go into a technical oriented faculty anymore, because of my age. Undergraduate programms are for 19-23 years old.

Save data in a videogame? JSON, and possibly binary blob.

I'm working on recreating this gif in Javafx. I can set the box heights in an animation timer, but it's very laggy. I can instead scale the boxes instead of changing the height, which allows me to cache the scaling and make it run smooth. The issue is that whenever I change the scaling, the lighting on the boxes gets fucked up, and I'm not sure why. Anyone here have any tips?

What language? In scala I'd just make it all serializable and write it to a file, I wouldn't care much for the underlying format. If I did care for the underlying format I could then rewrite the serializer without changing any of the surrounding logic using something like scodec.

hurr

By all means promote their degenerate lifestyle and campaign against evil white men. You'll end up on the rope soon enough...

you dont grasp the principle reason for the distaste libertarians have for unions. there are good and bad ways of associating.

What do you do when your program accomplishes what you needed but the program it self is a hot pile of shit?

Job well done!

Look up binary save file

I'm not exactly fond of python, so I don't know what the pythonian way is. My advice however is to follow the same method as in scala, make it serializable (JSON is a good choice) and then worry about how the serializer is implemented should you need it.

Of course I do. You hate unions because thanks to them you can't abuse people like this anymore:
>Ellen was the only child of Mary Hootton. When she turned seven, her mother brought her down to a nearby factory to add to the family’s meager income. After as many as five months of unpaid labor, she became one of the many children working at Eccles’ Spinning Mill. When asked about her workday, Ellen said it began at five-thirty in the morning and ended at eight in the evening, with two breaks, one for breakfast and one for lunch. The overseer, Mr. Swanton, explained that Ellen worked in a room with twenty-five others, three adults, the rest children. She was, in her own words, a “piecer at throstles”—a tedious job that entailed repairing and reknotting broken threads as they were pulled onto the bobbin of the mule. With constant breakage, often several times a minute, she only had a few seconds to finish her task.
>It was all but impossible to keep up with the speed of the machine as it moved back and forth, so she sometimes had “her ends down”—that is, she had not attached the loose and broken ends of the thread fast enough. Such errors were costly. Ellen reported being beaten by Swanton “twice a week” until her “head was sore with his hands.” Swanton denied the frequency of the beatings, but admitted using “a strap” to discipline the girl.
>The beatings, however, were not the worst treatment Ellen experienced at Swanton’s hands. One day, when she arrived late to work, Swanton penalized her even more severely: He hung an iron weight around her neck (there was no agreement about whether it weighed sixteen or twenty pounds) and made her walk up and down the factory floor. The other children heckled her, and as a result, “she fell down several times while fighting with the other hands. She fought them with the stick.”

Here one of my many attempts, the boxes seem to get darker as they get longer. Again, this only happens when I scale the node, not set the height.

Rust supports FP and it doesn't use GC.

these arent problems that unions solve, theyre solved by rule of law and notions of individual rights, given to you by the liberal movement.

also, what is your source for this? it sounds like socialist masturbation material to me.

Rust exists.

Is it just me or are there more rust shills than usual?

>rule of law
The law is enforced by man and man is not altruistic. Thus the most vulnerable need additional protection from the owners of industry.

nobody wants to hire dweeby code optimizers who are allergic to solving real world business problems. Instead they want pajeet shit rushed out fast.

If they don't have unlimited extent, they're not real closures.
If the variable bindings aren't identical between the closure and its environment, they're not real closures.

no.
There has always been a decent amount of rust (((shills))) in /dpt/. Long before 1.0

m8 i asked what the proper solution to it would be, not how to open a file for reading or writing.

ill look into it.

replace rust with any language

Id bet any amount of money youre not white probably Italian or Jewish or Slav

>The law is enforced by man
and man requires justice. basic bitch aristotlian politics has your objections solved there.

It's a fantastic book, but it is a difficult read. I advice you to visit the scala gitter if you need help, they helped me out a ton when I was learning. Also scala definitely has warts, but I think the language itself is fundamentally good and that odd behavior comes with the territory when you're actually trying to push boundaries

>nature is the the ultimate arbiter of virtue

Americans need to come with a warning when they're about to vomit some stupid shit from their mouths.

no, but he's the most convincing of your hippies.

Of course. It is the way it was programmed.

In real life you can hear them from far away at least.

yes, to trigger autists.

nature and nature alone provides the fitness function for any given thing, if it flourishes under nature it is therefore virtuous, if it does not then it is bad.

That's not what virtue is though.
Justice could be a virtue, nature is, even by your definition, essentially unjust.
Moderation could be a virtue, nature isn't moderate at all.
Courage could be a virtue, what you describe doesn't always favour courage.
{Honesty, Loyalty, Honor} could be a virtue, nature doesn't promote these at all.
None of the Christian, except Diligence (maybe) could be found in nature.

Also, nature is the biggest meme ever.

alright, need some help
been working on a C based interpreter for like 3 weeks and I'm having issues with how I'm handling the local variable stack but I can't pinpoint exactly where
I think logic is fine but It's not supposed to work that way.
can you Jow Forumseniuses help me out

Say you have the following:
if x is true
y = foo()
if y is true
z = bar()
else
z = baz()
endif
else
z = baz()
endif
return qux(z)

How would you avoid the else z = baz() repetition? This is one of the places I kind of think goto works fine but the language I'm using doesn't have it.

use pattern matching

if x && foo()
z = bar()
else
z = baz

Also doesn't have it.

I guess I simplified my code, the foo() is actually several lines but I think I'll move them to a separate function.

Thanks.

Functions/procedures are the primary means of abstraction. Even in OOP.
You should never hesitate to refactor code into a new procedure.

Java isn't even the best language in its category. unless you have no choice in the matter (like due to platform or workplace limitations), there's legitimately no excuse to use it over C#. i don't usually make such sweeping claims when talking about programming languages (since it's often "apples to oranges"), but Java and C# are so largely similar in design and practical application space that a general qualitative comparison is trivial - and it's a landslide. i know quite a few people who know / have used both (myself included), and not one of them prefers Java between the two (in fact it never even comes close). C# is simply a much better language. it manages to be substantially more powerful (when you need it), and yet also much more pleasant and less tedious to work with in the general case. the only argument i ever see against it in this context has to do with a lack of first-party support on non-Microsoft platforms, which (1) while valid in a broader/real-world context, has nothing to do with the actual language itself; if this is the only argument people can come up with, that's a pretty good sign for C#, and (2) is outdated; it took them a long-ass time to take the hint, but Microsoft did eventually figure out that the excessively proprietary nature of C#/.NET was the only thing holding it back, and pivoted to a community-driven/open-source/cross-platform development model some time ago

>author of many, maintainer of none
ugh why would that even sound appealing for any potential employer

besides Go, i doubt Google has them on anything important. Probably on various non-projects.

>nature is, even by your definition, essentially unjust.
nature defines the just, because it decides what persists and flourishes, and what doesnt. all virtues are derived from this ultimate good, the natural. from the natural we derive life, from life we derive those virtues that are specific to our own nature.

there is nothing but the natural, all else is superstition. there is no morality but that which nature lays out for you, as all else is artbitrary bullshit.

What is the use case for -fwhole-program when you have -flto?

you are not programming related

Fuck saturation fields

Programming is subset of anime therefore anime is programming related sweet summer child

It's just an alternative. You can either shove everything into a single translation unit and pass the -fwhole-program flag so it can assume all your symbols have internal linkage for better optimization, or you can use LTO.
