Which two methods from the Thread class must be used when creating/using threads in Java?

This thread is not here to do your homework for you.

I can't afford expert help

The constructor and .start()

I need a basic encryption algorith for a shitty non-important offline program.

Rijndael

you have, you're in /dpt/

It is really good for java though. Wish I has some Indian rupoos

Is LISP still used for anything these days? Is there any point in learning it?

a friend of mine is working as data scientist with some pajeets. he told me they understand shit of what they're actually doing

personally cant approve that

emacs for example.
and natural language processing, i know a company working with lisp for NLP

That's been going on for a long time. I was talking to a woman who was a programmer back when COBOL was a common language. Her company (insurance) kept bringing in green-card Indians and the like who would work for a fairly trivial sum in the US, but return to India with a substantial sum.

Anyway, she said they had to practically hang over their shoulder and tell them what to type. Some learned fast and were decent (few), most never bothered to catch on.
Eventually they eliminated her whole department and outsourced entirely.

I'm Rajeesh and I am C# expert employed in Birmingham. White people know no basic facts from Microsoft certification book and call themselves "programmer" . haha

Poor bait

Julia good

Trying to learn C from K&R's book.
This is my solution to exercise 1-14, anything blatantly wrong?
/* write a program to print a histogram of the frequencies of different characters in its input */

#include

int main()
{
int i, n, c, height, characters[27];

i = n = height = 0;
for (i = 0; i < sizeof(characters)/sizeof(characters[0]); ++i)
characters[i] = 0;

while ((c = getchar()) != EOF) {
if (c >= 'a' && c = 'A' && c = 1; --i) {
for (n = 0; n < sizeof(characters)/sizeof(characters[0]); ++n) {
if (characters[n] >= i)
printf("* ");
else
printf(" ");
}
printf("|%d\n", i);
}

for (i = 'A'; i

Carmack uses a scheme as a scripting language.
I was surprised to learn that some gamedevs I know use common lisp for prototyping and shit.

Works for me!

Nice! Thanks for looking through it

It's fine right now, but it still isn't "complete"...
My only complaint is that some of the compiler errors are trash, but that could be fixed in the future.

sourceforge.net/projects/win-agui

Jow ForumsOS when?

Nice. C#?

reminder to learn vert.x

It's called Gentoo

Wrong. It is called CloverOS

Most of Jow Forums would struggle to complete a basic gentoo installation. Where brains were not the problem, it would a deficit in will and attention span.

Read: Most of Jow Forums are kids or people that just need an email/porn machine.

lol i thought it was just a meme

brb writing a Gameboy emulator in Clojure. It even has a JIT

Whatever happened to ClojureClr? Why did the tards avoid "dynamic"?

Fuck off. I don't have an email.

Dunno I never touched it. re is "dynamic" tho? The "every type can be assigned to this variable" keyword in C#?

Yeah it is that. I read long ago they were avoiding dynamic something and chose to emit everything at runtime.

That sounds weird I should look into it. It's true that .NET has value classes and true generics so maybe this makes the Clojure approach a little bit harder.

The CIL level has good support for dynamic features. It would be hard in Scala's case but not Clojure which is much simpler and organized.

Ok, which one of you fuckers did this?

Did you know that Python is the fastest growing cancer?

can someone recommend me a text layout library for c++. ideally it uses freetype and is really low level, but can do shit like markup etc. it doesnt even need to render it, I will do that. but it should take a string and layout it for me.

implementation/undefined behavior

>doesnt even need to render it
>it should take a string and layout it for me
what

How many years until I stop making off-by-ones?

benchmark kun, iirc

you know put the glyphs together, do line breaks and shit

How different is C++ from Java?
I don't want to use Java anymore because Jow Forums told me it's for pajeets, and C++ code is faster

Can I just start writing C++ if I know the basics of C and Java

Having trouble with this python module.
if the folder ./module/ i have a config file
./module/classify.py
./module/config.json

if im inside module it finds the config

but if i call it from ./
i get :

FileNotFoundError: [Errno 2] No such file or directory: './config.json'
should't it check for the file relative to the module folder?

Very.
C++ is even messier. Prolonged exposure to C++ causes brain damage.
It'll give you a head start but you've got a lot left to learn.

Capitalism, Ho!

the greatest game known to man

yes you can.

C++ is a shit load of different ideas and principles put into on language. And the main difference to Java would be "No Garbage Collector"

Although its mighty as fuck. And C++17 is kinda fun and less cancer than older versions.
Optionals., Smart pointers ... makes your life a lot easier

Java isnt that bad aswell, its easy at first sight but thats what programming should be. Considering what design principles and architecture you plan to solve your domain problem should be the complex part

It is OK, user. Don't fight it..

it doesn't; access it as os.path.join(os.path.dirname(__file__), "config.json")

And after the code is in production it turns out that you really shouldn't have done X.

Thanks

>no golang

this explains a lot of the C/C+ questions on SO

And after the code is in production it turns out that you really shouldn't have done.

is this a good way to run several instances of other programs?
in the source code of said programs I send a signal to the parent process, which is this piece of code.
void sigproc(int);
void launch_other_program();

void main()
{
pid_t wpid;
signal(SIGUSR1, sigproc);
launch_terminal();
while((wpid = wait(NULL)) > 0);
}
void launch_terminal(){
pid_t pid;
if ((pid=fork())==0) { /* child process */
execv(path,NULL);
exit(127); /* only if execv fails */
}
}
void sigproc(int dummy)
{
signal(SIGUSR1, sigproc);
launch_other_program() ;
}

kek what a guy.

Programming isn't really related to maths (more to physics). In other words, you don't need to be good at maths.

thanks

what's the use of a linter vs just enabling all the relevant gcc flags?

linter might have more checks

what if you aren't using gcc?

Anyone used Apache Synapse before?

then i guess you enable whatever flags your compiler has. my question was for my usage, though

Linters tend to be more opinionated, which is a nice way of saying they flag tons of non-issues. Static analysis is really where it's at.

How much crap does apache actually make a year?
Everyday there is some {obscure name} apache product that I have no idea about.

apache is a graveyard where software gets donated when it's no longer relevant

What are some scenarios where self-modifying code is useful?

malware

Modify how? Like the ransomware that injected IL at runtime or a python program that modifies its useless text?

As in overriding its own assembly instructions

genetic algorithm, encryption/decryption. cheats

Look up the Wheeler Jump, though it's obsolete by now it was very useful on machines with no hardware stack back in the day.

nope, nope, nope
