How does one authenticate a user by HWID in a way that's not crackable in 5 minutes?
The way I'm doing it right now is making a libcurl http request to a php script on my server with the useragent equal to the encrypted HWID. The script then checks if that HWID is valid and if it is, gives a response of a pseudorandom base64 number that returns true when passed through a function in the program.
Is this even safe?

Help.

SO, hard question for all the 17yo Java-bashing edgelords here: if not Java, which programming language should be the lingua franca for 90% of generic Windows apps instead?

Anon, C is much, much simpler than C++. It's always better to learn C before C++.

Also one should always use

There are bindings for multiple languages but i dont think you'd want to use qt bindings for java instead javafx or even swing.

If you must use the JVM use scala and its swing wrappers for GUIs

First of all, you are wrong.
Second, java is garbage collected as well. The original question was, what should be used instead of java. C# is java but better in 99% of cases. (You could make some argument for java having better crossplatform support as of right now, but that's bound to change soon.)

What are you using to learn C? You're already doing loads better than most C programmers I see with only a couple of weeks. Like most people who learn don't even bother to know to use void to designate a function with no arguments.

Only criticism is inconsistency with if else and braces, where the if uses braces but else doesn't. Please use braces for everything even if it's annoying. It saves you from crappy bugs with scope.

http://programmers.stackexchange.com/questions/131377/whats-the-benefit-of-avoiding-the-use-of-a-debugger/131391

What looks like guessing from the outside often turns out to be what I call "debugging in your mind". In a way, this is similar to grandmasters' ability to play chess without looking at a chess board.

It is by far the most efficient debugging technique I know, because it does not require a debugger at all. Your brain explores multiple code paths at the same time, yielding better turnaround than you could possibly get with a debugger.

I was not conscious about this technique before briefly entering the world of competitive programming, where using a debugger meant losing precious seconds. After about a year of competing, I started using this technique almost exclusively as my initial line of defense, followed by debug logging, with using an actual debugger sitting at the distant third place. One useful side effect of this practice was that I started adding new bugs at a slower pace, because "debugging in my mind" did not stop as I wrote new code.

Of course this method has its limitations, due mostly to the limitations of one's mind at visualizing multiple paths through the code. I learned to respect these limitations of my mind, turning to a debugger for fixing bugs in more advanced algorithms.

>a disassembler on steroids that you can program.
That's what a debugger is you monkey.

Alright guys I'm in a computer class in college, just starting to learn basic Java, but my teachers given us a tough dilemma to get around for a project.
My problem boils down to the fact that getting making my double equal the results of an int divided by an int displays the wrong number. I'm having it print to 2 decimal points with %.2f%n , but even if I remove that it always wont do the math right. For example it keeps doing 25/6 as equaling 4.00. I know having just one of those numbers be a double makes it do the decimal math right but part of her assignment is the numbers were dividing with x/y HAVE to be integers, and with no extra variables we need to get a accurate 2 decimal point output in double. SO the requirement is basically:
int x;
int y;
double result;

and it has to be you input x and y as ints, and then in 1 equation calculate it:
input x
input y
results = x/y

but holy hell it won't work. How do I make it do the right math without making one a double or adding any more variables?

>I was not conscious about this technique before briefly entering the world of competitive programming

>>56746028
>I prefer to do by myself what I could get the computer to do for me
Your mentality is foolish.

>>56746024
cast to double first

result = (double) x / y

>>56746052
I think you have to do
(double x) / y

>>56746024
Take your homework somewhere else.

>>56746052
Don't encourage him

we don't have general artificial intelligence, the machine is not as smart as a reasonably competent human being, but of course a pajeet like yourself might need every assistance they can get

* ((double) x) / y

>>56745777
>>pointlessly typing unnecessary characters that in no way aid understanding of the code

The use of the "(void)" formal parameter causes the C compiler to explicitly check to make sure that no arguments are provided at the point of call. If you use the "( )" formal parameter in C, then that check is not performed (for compatibility with the old pre-prototype style).

Proof:

echo > x.c "void f() { }  int main() { f(123); return 0; }"
gcc -Wall x.c
# no warning !!!

I always use "(void)" in C so that the compiler will catch it if I accidentally pass any arguments.

The rule is different for C++. C++ treats "( )" identically to "(void)", because C++ doesn't need to worry about compatibility with old pre-prototype C code.

>>56746076
Why not just write it in assembly, so you can prove you are better than stupid pajeet tier gcc compiler! There is no way machine can do anything better than mighty you? You will surely write more optimal code

>>56746106
>Why not just write it in assembly
now that's a strawman argument

>the computer can't do everything yet
>therefore there's no point in making it do what it can to help speed up development and bugfixing
That's the mentality that says we should still program in assembler and nothing with a more advanced compiler.
That's the mentality that says we should write code in Notepad and nothing more capable.
That's utterly retarded.

>>56742484
Is this even any good?

the only excuse for something to go wrong at all is if you literally just wrote some new code, and then it should be immediately obvious want went wrong, so you should be able to fix it trivially without using a debugger.

You should always do that. Debugger usage is fundamental imo.

I'm about to ditch SFML (lack of stable C++ ABI forcing me to compile my own versions constantly, huge size, etc.), but what do I replace it with?

SDL or GLFW?

Both have all the functionality I need. I just can't decide. SDL is more widely used and I've used it a few times in the past, but GLFW seems to be even smaller than SDL. Meaning, even less chance of something that can break.

I hope to god you're not employed, you are a danger to any company's code.

The reason debuggers are useful are because in most cases, they are faster and more precise than you sitting and thinking "hmm....

>>56746649
Because Java has a lot of momentum behind it, still. You'll be employable if you're good at Java.

Universities still teach it, probably a combination of their teaching staff having more experience with Java, and a vague nod to Java at least traditionally being more open than C#.

I know you might not like to hear this, but Java and C# are pretty much the same language if you squint a bit. You can train someone who knows one to use the other in a couple of weeks.

yeah, but the landscape is quickly becoming such that you'd be more employable with C# if that's not the case already, and C# is a better language in general, so there's no real reason to go with Java instead nowadays

>Universities still teach it, probably a combination of their teaching staff having more experience with Java, and a vague nod to Java at least traditionally being more open than C#.
i'm sure those are exactly the reasons why. that's not really a reason to learn Java over C# if given a choice, though

>I know you might not like to hear this, but Java and C# are pretty much the same language if you squint a bit
if you really believe this, then you definitely don't know C#. they share many, many similarities, of course, but C# has quite a few significant features that Java has no sense of whatsoever, becoming proficient with which would take more than a couple weeks

My uni teaches everything from racket in the first year, to C for system programming, Java and processing and shit for other courses.

>>56746890
I didn't say they exclusively teach Java. Mine taught Haskell, C/C++, Java, and Prolog. The choice of language was largely incidental; the intention was that we would be able to pick up any language relatively quickly.

>>56746842
I agree with you on everything except the jobs.

Java is easily still the biggest market for jobs, although C# is the only close contender. C++, C, and Python are at the next tier.

If you really want to guarantee a job, you'll learn both Java and C# to a moderate level of proficiency. This is no easy task, though, because I do agree that they are VERY different languages.

>>56746958
>I do agree that they are VERY different languages.
Where do people get this notion from?

They only seem very different if they're the only languages you know.

Linus Torvalds is lucky. He produced a product he expected to go nowhere, and people ended up both contributing to it and using it. He makes money because large corporations ended up finding that product more useful, say, any of the BSDs, and they donate to the Linux Foundation because they want to keep that product being developed.

Most people will not end up like Linus Torvalds. They may come up with a good idea, but it ends up not being used. They may come up with a bad idea, and only end up wasting their time. Most have no idea about what the market wants, and quite honestly, that's fine. Not everyone has to be an entrepreneur, and if you can make 100K implementing someone else's ideas, whether they turn out great or turn out terrible, you still earned yourself some decent money.

this is very far from true. some examples: user-definable value types, user-definable conversions, operator overloading, significantly different/more powerful generics (boxing/unboxing, covariance/contravariance, constraints), delegates, better native interop (p/invoke, cli), unsafe blocks/methods, nullable types, linq, initializer expressions, implicitly types locals, extension methods, ref/out parameters, params (varargs), unsigned types, and attributes. that's not everything but it gives an idea

>>56746958
it may not necessarily be winning out yet, but C# is much more prevalent in the industry than people think. it's not immediately obvious because a very popular industry use case is internal tools, pipelines, testing, and automation. it's frequently used internally by companies that use completely different languages/technologies for their actual application/service backends/frontends

Ofc it does semantically speaking. If you use "very" for java and C# what do you use for java and prolog? Extremly? Whats only different? Are C and Java more or less very different?

Some of these are no longer true, due to some recent attempts by Java to catch up to C#, but at least this can aid the conversation.

I'm not picking a side, I just come bearing information.

>>56747169
just because it's not as extreme as haskell vs php doesn't mean they aren't every different, and if you can't see how java and C# differ in very significant ways you don't know them well enough to make that judgment

things aren't black and white fucking autist

this connects back to the previous sperging about learning a language vs learning a syntax, just because, java and C# have a similar syntax to each other doesn't mean they're similar languages, fucking pathetic retards

I know they are different but in language you define adjectives "short" in relation to "long", otherwise it makes no sense to speak of short things if you dont have concept of long. Same is true with close. In English we only have comparative and superlative we cant use comparative for such closely coupled languages or we cant define others well. It becomes meaningless

Arguing semantics is just silly.

If you'd like, we can say that Java and C# are "significantly" different, but this obviously depends on what you see as significant.

I would say that the average programmer who is reasonably knowledgeable in Java and C# would agree that they are very different languages, on their own merits.

Once you include their standard libraries, their toolsets, and their other non-primary integrations (Swing, FX, Xamarin, .NET Core, etc.), the gap widens.

>>56747258
they ARE very different to each other, how else do you think people end up with the belief that one is vastly superior to the other, that one is a top tier language and the other one is bottom trash

Compressing works by removing redundant information. Take a file made that repeats the same information over and over, by just leaving "insructions" how to recreate the original you can save a lot of space.

e.g.

original:   AA AA AA AA AA 00 00 00 FF
//by just saving the data as a byte followed by the times it repeats you get
compressed: AA 04 00 02 FF 00

same information less space.

If the entire image is one single color uncompressed, then you can easily shrink its size (relatively speaking) down to almost nothing.

You'd only need information storing the dimensions and the color.

Syntactically the languages are very similar, it's C++ syntax all over again.

The type systems are roughly the same. No higher-kinded types. Nulls. They both have closures (delegates in C++; anonymous inner classes in Java because fuck you). Neither has macros. I'll give you that they implement generics a bit differently. Both use OOP with interfaces and superclasses. I'll give you that C# has extension methods but they're toys. Neither has typeclasses. Neither has purity enforced by the type system. Neither has tail call optimization. C# has properties, surprise, it's nothing. Both of them have the blight that is reflection.

Maybe this is it. They're afraid of Java programmers taking their jobs. That's why they're so adamant that Java and C# are very different and that it's impossible to pick one up when you know the other without having to start from scratch.

use Text.Printf.printf

>>56747890 is still an idiot for replying to >>56747855 instead of >>56747824

No, one mightn't.

>>56748188
Noo C# and Java are so different that once you learn C# extremely well you have to spend years learning whole new paradigms learning drastically different tooling and jvm its so different it makes big difference when programming. It would take years to switch coz you know they are "very different"

Difficult to tell, given some of the posters here.

What do you guys think of Libgdx?

Yup.

I know i was trying to find most closely related languages i could think of... Its hard. Should have taken american and British english

>>56748238
Don't use it, it is harmful software. Use a free alternative from the FSF.

>>56748238
it's trash it's what mexicans use for their babbys first 2d android games

>>56748245
>>56748272
What should I use then?

>>56748283
depends on what you want to do

>>56748283
if this is your first game you might as well use libgdx so at least you can focus on game design and actually making stuff. For second one you can try and pick up better tool.

>>56748289
2d games.

>>56748346
Then just write your own blitter.

of course it would be easy to *pick up* one coming from the other, but you must have an extremely lax definition of "proficient". and you clearly underestimate the number of differences between the languages in general, let alone the number and significance of features C# has that Java doesn't

>That's why they're so adamant that Java and C# are very different and that it's impossible to pick one up when you know the other without having to start from scratch
>without having to start from scratch
literally nobody said this

>>56748392
we're not even at 310 you fucking retard

>>56748404
just use libgdx.. Rendering stuff to screen is smallest part of game...

>>56748346
it's all trash, like don't use gamemaker, there are people who use unity engine for 2d games but that's retarded and only relevant if you want to learn the unity engine, you could do it with plain opengl but that's only relevant if you want to learn opengl

The original code is in >>56745666, >>56747799/>>56747824 just copy pasted it and moved it into a separate function.
