>Weakly typed OSs
This has literally no meaning.

In any case, the poster who claimed that .vimrc is not a valid filename in Windows is wrong.

https://msdn.microsoft.com/en-us/library/windows/desktop/aa365247(v=vs.85).aspx

Windows may have some odd quirks, but requiring files to match the standard filename.extension format is not among them. Filenames are allowed to begin with periods .likethis, are allowed to have no periods at all like_this, and may have multiple periods .like.this

If filenames beginning with periods were not allowed, Git would not work on Windows at all, as all of the files associated with the repository are stored within a folder called .git

working on a template class on php. nothing special really. just trying to replicate what i used (like smarty, raintpl and such) and make it as flexible as i can. i'm probably gonna port it to javascript when i can. i fucking hate all the js template engines i saw so wish me luck.

>This has literally no meaning.

>>58437860

Weak and strong typing are terms that can be applied to programming languages, not operating systems.

>>58437886
It applies to anything with different kinds of values.

>>58437860
>>58437886
>>58437915
You can't have "strongly typed" systems since files are just collections of bytes. You can't enforce an interpretation on all programs that read them. And if you do, you have a useless mess and not an operating system.

>>58437931
>files are just collections of bytes
in a weakly typed system

>>58437931
Types are specifications, not interpretations.

>>58437778
At least you gave up wrapping it in code blocks, Rajesh.

>>58437973
>>58437994
How would it make sense to prevent programs from writing arbitrary bytes to disk? And what purpose would it serve?

>>58437853
>pearl counter
>not selling it as "anal bead counter" on apple app store
Countless apple users (aka: faggots) are dying to throw money at you so they could count anal beads before and after they put them up their asses.

>>58438013
You don't. You just can't write arbitrary bytes and say that it's a certain type of file.

>>58438013

And secondary and primary memory aren't that different.
An OS is a piece of software too, it is a program (that has sub-programs).
So the same things that apply to the programs you'd write, make even more sense when it comes to OSs.

This thread is pathetic. It is not about programming. It's just a bunch of computers illiterates and first semesters memeing about whatever they just learned.

A quick search shows that most arguments used here are not original and have been copied from some trendy tech blog or other shit site.

The only real programming questions I have seen so far are from beginners(it's fine to be a beginner btw).

This entire site is shit and I don't know why anyone would regularly come here.

>People unironically use JavaScript's new classes even though it's just syntactic sugar for prototypes and it still requires you to use the problematic 'this' keyword.

Why do people insist on using shitty parts of a language?

>>58439351
How is "this" problematic? I've never programmed in js but picked it up eventually and understanding how it works took me maybe an hour.

People are so indoctrinated they can't imagine programming without classes even if they have something equivalent.

>>58438861
Wrong, Java is the best programing language in existence.

>>58439742
yaasssss, preach it sista!!

>>58439372
Because the value of 'this' isn't always the same, say you add a forEach loop in your constructor, the value of 'this' won't refer to your object so you have to use ugly workarounds like call, bind, and apply.

It's just not worth the hassle, even when you fully understand it, it's something you will keep tripping over. Why use the 'this' keyword when you don't have to? The only instance I can think of is when you're creating like over 10,000 objects and the extra performance you get from prototypes is necessary.

is calculating an index for a 1d array out of an x and y value more efficient than using a 2d array?

>>58439856
What do you think a 2d array does?

>>58439864
x: geht the pointer two the array on this position
y: direct access to the value of said array

>>58439856
I would think it'd be identical either way.

2D arrays aren't necessarily 2 layers of indirection (jagged arrays). In C or C++ it's equivalent to just using a 1D array.

The fact that so many books still name the Beatles as “the greatest or most significant or most influential” rock band ever only tells you how far rock music still is from becoming a serious art. Jazz critics have long recognized that the greatest jazz musicians of all times are Duke Ellington and John Coltrane, who were not the most famous or richest or best sellers of their times, let alone of all times. Classical critics rank the highly controversial Beethoven over classical musicians who were highly popular in courts around Europe. Rock critics are still blinded by commercial success. The Beatles sold more than anyone else (not true, by the way), therefore they must have been the greatest. Jazz critics grow up listening to a lot of jazz music of the past, classical critics grow up listening to a lot of classical music of the past. Rock critics are often totally ignorant of the rock music of the past, they barely know the best sellers. No wonder they will think that the Beatles did anything worthy of being saved.

C is a simple and concise language with no real feature bloat over it's 45 year history.
Your knowledge will carry over to any modern language.

C++'s biggest mistake was being C compatible, and gets progressively more bloated every 4 years. It's gotten so bad that the creator himself has attempted to redefine a C++ Core language that ignores nearly all C++ features because using all the features is the fastest way to shoot yourself in the foot.

do

which will also consume the \n character you entered

Yes, because 00000000 00000000 11111111 11111111 is:

1 + 2 + 4 + 8 + 16 + 32 + 64 + 128 + 256 + 512 + 1024 + 2048 + 4096 + 8192 + 16384 + 32768 + 0 + 0 + 0 + 0 + 0 + 0 + 0 + 0 + 0 + 0 + 0 + 0 + 0 + 0 + 0 + 0

Which is:
65535

Which is:

65535 % 16 = 15
65535 / 16 = 4095

4095 % 16 = 15
4095 / 16 = 255

255 % 16 = 15
255 / 16 = 15

15

Which is:

(0x) FFFF (because 15 = F in hex)

>I'm calling the function several times a second
You didn't read me. Do you do the test each time you call it?

>>58441245
Do the first one then so you don't constantly set up a stack frame only to have to immediately tear it down again

>>58441163
For that, you have to flush the output buffer.

scanf("%d\n", &choice);
printf("input is %d\n", choice);
fflush(stdout);
c = getc(stdin);

When you execute printf the contents are not actually printed immediately, but placed in a buffer. Each call adds to the buffer until the program reaches a point where it decides to flush the buffer (actually send the contents to the terminal and clear it). In cases where you want to control when this happens, you can use fflush or use non-buffered IO functions.

>>58441262

>>58441265

hey /g/, I'm a beginner trying to find a way to write a program in python like this:

I want it to load as in a terminal, kind of like old-school text-adventures. When you run it, it gives you some opening script, and then you can use some basic commands to do things, mainly running python files, and maybe a way to organize the particular directory they're in, as well as launch them in an editor, if I choose. I want to have it as my interface for running web scrapers, and looking at their results.

I tried out the click package, but it doesn't seem to fit my needs. Does anyone here know of a a way to create something like this?

fite me

One of the perks of working on Go these past years has been the chance to have many great discussions with other language designers and implementers, for example about how well various design decisions worked out or the common problems of implementing what look like very different languages (for example both Go and Haskell need some kind of “green threads”, so there are more shared runtime challenges than you might expect). In one such conversation, when I was talking to a group of early Lisp hackers, one of them pointed out that these discussions are basically never dogmatic. Designers and implementers remember working through the good arguments on both sides of a particular decision, and they’re often eager to hear about someone else’s experience with what happens when you make that decision differently. Contrast that kind of discussion with the heated arguments or overly zealous statements you sometimes see from users of the same languages. There’s a real disconnect, possibly because the users don’t have the experience of weighing the arguments on both sides and don’t realize how easily a particular decision might have gone the other way.

>>58442387
Go away

>>58442387
Language design and implementation is engineering. We make decisions using evaluations of costs and benefits or, if we must, using predictions of those based on past experience. I think we have an important responsibility to explain both sides of a particular decision, to make clear that the arguments for an alternate decision are actually good ones that we weighed and balanced, and to avoid the suggestion that particular design decisions approach dogma. I hope the Reddit AMA as well as discussion on golang-nuts or StackOverflow or the Go Forum or at conferences help with that.

But we need help from everyone. Remember that none of the decisions in Go are infallible; they’re just our best attempts at the time we made them, not wisdom received on stone tablets. If someone asks why Go does X instead of Y, please try to present the engineering reasons fairly, including for Y, and avoid argument solely by appeal to authority. It’s too easy to fall into the “well that’s just not how it’s done here” trap. And now that I know about and watch for that trap, I see it in nearly every technical community, although some more than others.

How is c++ easier to learn than C? C has like less than 30 keywords and basically no standard library.

Modern C++ requires
>autistic workflow for compiling, linking, managing libraries, getting code completion and other expected features in a proper IDE
>requires finding, installing, and choosing 3rd party libraries

C++ is a good language that isn't suited for learning or teaching programming because of the added steps in workflow and the choices that the programmer needs to make in order to use the language to its fullest.

Learning C++ as your first language is like learning to run roleplaying games through GURPS. Its retarded and the only reason to do it is so you can say you started with C++ because you think that makes you look more intelligent or cool or something.

Well...

C++ could be a good starter language if you're learning programming from someone in your immediate family and he/she loves C++ and you have immediate access to experience in person troubleshooting and help. You'll waste a lot of time asking easy to answer/fix questions for stupid shit while learning stuff that has nothing to do with programming at all and is more just weird quirks of C++ workflow and development.

[spoiler]Everything I just typed was regurgitated information I've gathered from watching game dev youtube videos. Is it accurate at all? I installed c++ and learned some of it from Bjarnes C++ programming book but it seemed like old retarded outdated C++ and I just switched to using Lua instead and I like Lua a lot.[/spoiler]

>>58442804
It has nothing to do with floats.
It's to do with main.

>>58442822
IIRC ANSI C implicitly makes main function to be integer.

>>58442840

>>58442773
A senior programmer does not have a GitHub. Never had one. Red flag or not?

The worst part of C is having to surround function bodies with braces. Instead, all global declarations should come before the first function, and function definitions should start with a unique keyword that ends the previous function. Also, you shouldn't be able to call a function before it's been defined. Recursion was a mistake.

>>58442818
No spoilers on /g/. I wonder where you could possibly be from?

how would you implement a modulus?

i know you can do like

mod(a, b)
rem = 0
while(a <= b)
--- a -= b //bounds check too
return rem

but thats silly

>>58442880
What the fuck are you talking about?
I know C, and I regularly use C11. Both GCC and Clang, other only relevant C compilers, support it and even default to it.

>>58442892

Maybe just ask him why?

I keep all my stuff in btibucket and use GitHub to find stuff from others.

But I would expect a SeniorDev to know Git. If not, he can still be an outstanding programmer, but then you need to get him fit for git in a few days. Depends on the "complete package"..

>>58442978
Why are you assuming he doesn't know git just because he doesn't have a public github? github is just one of many, many different ways to use git.

>>58442953
Most of the stuff C11 adds is pretty niche.
Most of the interesting stuff in added in C99.
Just remember, THIS is invalid C89:

#include <stdio.h>
#include <string.h>

int main()
{
    char buf[32];
    fgets(buf, sizeof buf, stdin);
    size_t len = strlen(buf);
}

If you were seriously required to write strict C89, you could just declare size_t len at the top and be done with it.

Working with Python is nice and relaxing, easy. What we do now is using C++ stuff that are wrapped with Python.

Not to mention if you ever want to do ML you are going to learn Python anyway... I mean C is great and stuff, but ML in C is time consuming as fuck.

Yes, I know. But I picked an extremely simple situation that one would think works.
There is all sorts of other, useful shit they added in C99.
Designated initialisers.
Variadic macros.
Well-defined division/modulo (was implementation defined for negative numbers in C89).
Restrict pointers.
and so on.

Python is terrible at that compared to other langugaes though. That's why it's hated so much by good programmers.

Ok guy, go back to scripting websites now.

>>58443170
If you actually think Python is good in any situation then you should get some help.
I recommend lurking more.

>>58442745
Do you think that a language maximizing type safety, abstraction capabilities and statelessness is the most desirable?

>>58443200
None of the shit any language does is "strictly necessary".
Why don't we all just program turing machines?

But really, C99 adds a lot of useful features, including ones that aid optimisation and make the language nicer to use in general.
It doesn't violate the 'spirit of C'. It doesn't bloat the language like C++.

>>58443208
You seems to know a lot, would you be nice and actually show some proof ?

Being a mathematician doesn't imply being a good programmer

No. They're totally useless.

Aside from Java, everything is good. And it has its fields.

Go do Data Science with C/C++ you'll get fired the first month, for not finishing any project, even half way through.

But that's wrong, commie

for i=100,1,-1 do 
  if(i % 5 == 0 and i % 3 == 0)
  then
    print("fizzbuzz")
  elseif(i % 5 == 0)
  then
    print("buzz ")
  elseif(i % 3 == 0)
  then
    print("fizz ")
  else
    print(i)
end
end

job pls?
