Trying to get my image viewer to properly display gif images. The gui library does not do this natively, so displaying animated gifs is a real ordeal. I'm probably going to have to write a lot in the mailing lists because most of the time displaying a gif is nowhere near this easy/smooth.
>>54690831
what does your picture (raytracer ?)have to do with it?
>>54690843
What's the problem?
Deconstruct the gif into frame delay/ogl texture pairs and just play those.
>>54690856
that's not me.
Redesigning C++ 3D engine core in C.
Fucking hell I forgot how fun C really is. The lack of safety measures like protected, private and constructor/destructor was intimidating at first but you just feel free in this language. I was even able to drop my shitty inheritance system to an understandable struct system.
Probably gonna make the full switch.

When you won't be scared by allocated space, you will shit on C++.
How do you develop on Windows?
Do you install all the needed shit locally and deal with the Windows environment or use Virtual Machines or something like Vagrant?
What about the command line? Powershell? Cygwin? or just something like Cmder that makes cmd less painful?
>>54690943
Are you retarded?
what should i make?
>>54690867
I'm splitting the gif into its frames, grabbing the delay for each frame, and then looping the canvas draw call, sleeping for <delay> seconds. The problem is when it comes to gifs that have been optimized to have a lot of transparencies and expect the background to still be displayed so the other frames and be displayed on top of that. If I always display the background, expecting those kinds of gifs, then the Sif gif will look funny because the background frame will always be displayed.
There's also a problem with grabbing the frames of the large gifs and loading them into a bitmap% object - something about LZW compression being out of bounds, I have no idea what's going on with that. There's also a gif or two that have an "unexpected EOF" error when loading into the bitmap% object, but they load just fine in Firefox or Eye of MATE.

Do you just have a pointer to a parent in your child struct? ieclass Child : Parent {
//....
};
// becomes
typedef struct Child {
Parent *parent;
//...
};
?
It's not exactly the same though, because then the child gets everything in parent, not just protected/public stuff, but that honestly doesn't matter/make a difference

Heh... not bad, kid. Not bad at all. Your meme, I mean. It's not bad. A good first attempt. It's plenty dank... I can tell it's got some thought behind it... lots of quotable material...
But memeing isn't all sunshine and rainbows, kid. You're skilled... that much I can tell. But do you have what it takes to be a Memester? To join those esteemed meme ranks? To call yourself a member of the Ruseman's Corps? Memeing takes talent, that much is true. But more than that it takes heart. The world-class Memesters - I mean the big guys, like Johnny Hammersticks and Billy Kuahana - they're out there day and night, burning the midnight meme-oil, working tirelessly to craft that next big meme.
And you know what, kid? 99 times out of a hundred, that new meme fails. Someone dismisses it as bait, or says it's "tryhard," or ignores it as they copy/paste the latest shitpost copypasta dreamt up by those sorry excuses for cut-rate memers over at reddit. The Meme Game is rough, kid, and I don't just mean the one you just lost :^). It's a rough business, and for every artisan meme you craft in your meme bakery, some cocksucker at 9gag has a picture of a duck or some shit that a million different Johnny No-Names will attach a milion different captions to.

>>54692334
I assume the problem lies within glob that stores a gigantic list of paths, I could be wrong, but try using os.walk() which is a generator, something like this:data = None
for root, _, name in os.walk(data_path):
path = os.path.join(root, name)
with gzip.GzipFile(path, 'rb') as r:
data = r.read()
with open(path.replace('.gz', '.txt'), 'wb+') as w:
w.write(data)
The caveat here is that the data_path will have to contain only the .gz files because you can't match just the .gz extension with os.walk() unless you add some extra check within the loop.
>>54692327
I'll give this a shot now.

What exactly do you want it to do? Clippy and friends were integrated into a certain application, and noticed when you were doing something specific, etc. Do you want that? Or do you just want a generic 'assistant' that you can do something with? What would it do? Do you type commands to it, pick options from a menu, etc?
Anyway, if you use C++, you can use SFML or SDL for graphics. If you use Java, then libGDX is a good, easy choice. You'll probably want to learn how to use whatever graphics library you're going to use before starting your project.

This is a bit more involved than you may think, but I know there are NLP libraries for Python. You could do your backend in Python and your frontend in Java/C++ I suppose. It's really easy to open browser tabs etc and look things up in Python. Perhaps you could do "Find a grocery store" and it opens up a google maps search for "grocery store" or something.

Basically, my idea is to have the user supply strings representing posts from boorus and instantiate them so I can do work with them afterwards, so "d123" would create Danbooru(123). Is there any good way to do this dynamically, or do I just need to parse the string and instantiate an object manually?

Scheming is F U N.
Scheme is beautiful.
>>54693883
Basically this. Abstract the function of at least the primary for loop into a new function. That way, when you get to i == 8, you can just say return and that will return control to the while statement. Also, I have no idea why you're using while(True), since that's usually a code smell, unless you're writing a daemon or something.
>>54693866
When it's nested like that, I think you only break out of the outermost loop. Some languages like Swift allow you to label your loops, so that you can break out of a higher loop, but I guess for your case you would need a signal variable after you break.

LISP is one of those things where you realize we knew about useful abstraction 110 years ago, but nobody really realized how good it was until we were inundated with shitty 2/3GL languages.
It's refreshing, like an ice-cold glass of lemonade on a hot summer day.
>>54693908
the while(True) actually goes around the whole process, I just moved it down so it was visible
the program is essentially a thread updater, so you never need to actually close that loop
>>54693938
>>54693915
Maps and filters be the way to go. Consider S-expressions over xml too because then you can have a more intimate relationship with the data.

I want to print files on Qt but i don't find a single way of doing so
I can only print QStrings QImages
is it possible to print files? Like picking a file and then printing it? What if i export files and then print a PDF through Qt?

Lisp has no abstraction at all. Macros can distinguish between code written with if and the equivalent written with cond. Researchers abandoned Lisp because they wanted abstraction.

Nigga that's a procedure application and fizzcheck returns nothing. Do you mean(begin (fizzcheck) ....?

i don't know what those words mean. i intended it to fizzcheck x as in print fizz if x%3=0, then buzzcheck as in do the same with 5, and then if x is less than 100 run fizzbuzzloop again incremented by 1. and now i realize that it will be doing fizz3 instead of fizz but still i want to get my wrong implementation working. installed guile and i dont see how its any different from mit scheme

Lisp dialects were taught in CS 101 for a long time, so knowing Lisp only means that you're on the level of someone who took a few CS 101 classes.
If you want to be a better programmer, you should learn about algorithms and data structures, not languages.

Lisp machines were slower for running Lisp than a 1987 PC or Mac.
>Later desktop computers built by Apple and IBM would also offer a simpler and more popular architecture to run LISP applications on. By 1987 they had become more powerful than the more expensive Lisp machines. The desktop computers had rule-based engines such as CLIPS available.[28] These alternatives left consumers with no reason to buy an expensive machine specialized for running LISP. An entire industry worth half a billion dollars was replaced in a single year.[29]
>>54694231
i said the syntax is what makes lisp, lisp. if you have a different syntax, it's not really lisp any more. please explain how you would make a lisp with C syntax.
>>54694176
Procedure application is anything that isn't a special form like define, cond, if that happens with parentheses.(+ 2 4)is applying 2 and 4 the value of the symbol + (a procedure).((lambda (x) (+ x x)) 2)is applying 2 to the value of the expression(lambda (x) (+ x x)), a procedure which takes one argument.
Your code is trying to apply the rest of the stuff after (fizzcheck x) to the return value of (fizzcheck x). (begin ...) starts a block where the items are evaluated sequentially and the last item is returned.(begin 1 2 3 "GO!")returns "GO!"
>>54694257
oh yeah you right family
>>54694271
ok, so i do (begin (first task) (second task) (etc)) like that?
/homework/
so lets say we have an array{5,4,2,1,3}
and using two different algorithms, Median and BruteForceMedian (implentation already done and not relevant), I need to measure the execution time and number of basic operations for both.Specifically you are required to test both algorithms with the same data. Not only must you test both algorithms with the same arrays of data (same size and same elements) you must use the same instance of the input data.
This is in C++. My question is, how do you use the same instance of an array when the algorithms modify it?
Do I need to be looking into pointers or something? I get OOP but trying to do this in C++ isn't clicking with me.
>>54694330
you wut
just pass a copy of the array to the argument
im sure you can measure execution time, but for number of basic operations, does that mean you have to count by hand?
Or maybe check the asm output from the compiler?
>>54694245
I'm not sure what you're trying to get at. Computers were, in general, slow.
Home computers got incredibly fast of the course of a few years.
>>54694242
Jesus god. I see what's wrong with Yankees and south Americans now though. They're getting blasted with India's poo.
>>54694330
You don't write algorithms that modify it. your implementations of median and bruteforcemedian have to generate a copy at each iteration rather than modify at each iteration. Have fun sounds like your professor is a smug functional programming weenie.
>>54694242
you're not special for using a lang like lisp or haskell, anyone could learn those languages if they wanted to
i want my program to count the pages in a file to print them out however it can't read files like docxs and excel etc so i was thinking about converting the files to pdf and then it can process them,
I'm on windows is there any command line tool to convert files to pdf?
>>54694363
If we could pass a copy they wouldn't have said what they said.
>Not only must you test both algorithms with the same arrays of data (same size and same elements) you must use the same instance of the input data.
int []a = {1,2,3}
int []b = {1,2,3}
is not allowed according to the specifications.
>>54694370
>You don't write algorithms that modify it.
The arrays were given in pseudocode and we're not allowed to change them. They MUST modify the arrays.
>>54694386
>I can't read files like docx and excel
Aren't they open source formats? I know docx and xlsx are. Look it up. I'm sure you can count sheets in an xlsx, not sure about pages in a docx.

>How do you develop on Windows
Personally...
MinGW-w64 / Git Bash (although I've heard MSYS2 is a bit better)
Sublime Text
And that's it. Sometimes I use Powershell for a few things, but otherwise, just GCC/Make/Bash/Sublime.
>>54695304
depends on the program, a hobbyist program/library with around 1-10 thousand lines of code might be a few weeks or a few months, a big program could be in development by dozens or hundreds of programmers for years or decades
>>54695304
A "regular" program is very vague. Say you did 80 lines in 30 days, that would be 2.4K lines. 1 mil would be 33K lines per day. This is assuming one developer.

Look at the process to calculate determinants at the top. It's recursive, and it seems like it calculates the same thing over and over, like recursive fibonacci. You might be able to simplify it there.
