thanks for the pic
So i have a Qt application with 50+ ui elements, with tables, input fields. Also im loading huge, 100MB+ images and processing them in different stages. I need to create a save/load project function and im not sure how i should do it.
I dont know if saving the data to a zip file or just putting them into a folder would be best. Either way with all the images the save would take almost 1Gb.
Also how do i save and set the state of the ui elements without hiccups? I need to block signals globally thats for sure.

Hey /dpt/, I could use a small nudge in the right direction.
I have a large data set which contains pairs of IDs, representing connections between nodes. I can also look up the value of each node.
How would I go about efficiently calculating:
- Which nodes are exactly X connections away from a specific node (while going the shortest route)
- Which nodes are exactly X connections away from *any* node with a specific value
I'm having trouble finding resources for this specific case. Any ideas on algorithms to use, or just general approach to the problem? I'd rather not brute-force it and have my program take hours to complete.

Why is the ML family of languages so cucked?
Why is the lisp family of languages even more cucked (shit or missing type system, no TCO in clojure, barely functional constructs in CL and no standard update since 1994 with no plans to, most don't do parallelism either, none have a significant userbase except CL and racket, a lot are full of bugs and leak memory, etc.)?
Why is there no good functional programming language that is actually usable in practice?

No, they are for describing common patterns in OOP design. Whether those are easier to implement in/native to functional programming is irrelevant.

>>51982401
Brick is a table.
That table has an index named color with 1 value assigned to it (yes one, not three, you disregard the latter two).
You iterate over the brick table as if it was an array of elements.
You then try to print brick.color[0] which is an integer, not a table.
Also, Lua indexes start from 1. Read the tutorial & introduction, you've no idea what you're doing as of yet.

I know Lua indexes starts from 1, the for loop was just my way to discover if I can do something, but I didn't know the last two are excluded in the assignment.
>>51982608
Your loop doesn't make much sense anyway, you iterate over the brick table (which has just one element named color), and for each iteration you print brick.color[0]. I think you want something like this instead:local function GetRandomColor()
return math.random(0, 255), math.random(0, 255), math.random(0, 255)
end
local brick = {}
brick.color = {}
brick.color[1], brick.color[2], brick.color[3] = GetRandomColor()
for _, v in pairs(brick.color) do
io.write(('Color: %d\n'):format(v))
end

Eh do you mean if a particular equation has only integer solutions or not?
In terms of programming it's what YOU want as the result - if truncation towards zero is ok, use integers.
If you want floating point, use floats.
If you want exact rationals, use a pair of numerator/denom numbers, etc.

PHP however thinks true = false
"foo" == TRUE, and "foo" == 0… but, of course, TRUE != 0.
>>51982955
=== doesn't compare the types, then perform == if they're the same. It's a comparison operator without coercion. Because == still has to check the types of both arguments, and then tries various ways of coercing each one, it's slower than ===.

I'm in need of some optimization algorithm help.
I have x number of objects that have a start and an end coordinate. I need to determine the order of these objects so that the distance in between them (distance from the end of object 1 to the start of object 2 + from the end of object 2 to the start of object 3 and so on..) is as short is possible.
I can't really brute force it, because the number of ordering permutations is the factorial of the number of objects, so it grows ridiculously large after a small amount of objects.

md5('240610708') == md5('QNKCDZO')
The secret is that

md5('QNKCDZO') is '0e830400451993494058024219903391'.
Both are of the form 0e{bunch of digits}, a valid scientific notation. So when PHP's == decides to convert both sides to numbers to see if it can get a match, they're both converted to float(0), and thus the equality is true.

Because PHP was made by idiots for idiots, and has an absurd paradigm of abandoning all pretense of consistency or logic in favor of "making sense" (in the way 2 == "2" makes sense).
>>51983474
It's kinda useful when comparing input from a 3rd party and you don't care too much about type.

sorry to tell you this but the C++/Java style of OO is actually a minor niche of what OO was originally designed to be in the orginal Carl Hewitt's actor model. C++ basically bolted on a very static concept of OO by combining C structs with functions. The OO system in Ocaml is far in advance of the rudimentary OO that has become standard in most languages
>>no parallelism in 2015
if you want to build huge scalable servers you should be using Erlang/Elixir
>>different operators for floats and ints
part of the type inference system, floats and ints would have to be explicity defined without these operators
>>standard library is borderline unusable, so everyone uses either batteries or core, with lwt or async for concurrency, in any combination, increasing fragmentation
by unusable you mean there is no standard library ecosystem that does everything for you do you dont have to write any of your own libraries. This is a sad fact that universities produce code monkeys who are incapable of even implementing a library on their own and are completely dependent on having others make black box libraries that they use blindly without even understanding how these libraries are implemented. Its should be noted that most bloated software today is a result of overuse of libraries and implicit trust that libraries will always seamlessly integrate with eachother.
>>effort gets repeated from scratch every few years instead of being built upon (see: parallelism, jane street and some dude for his PhD both tried, both from scratch, and ocamlpro's current attempt is also from scratch)
The fact that Ocaml has a set of different sets of libraries is a testament to the fact that Ocaml is not concerned with non-changing standards but is always striving for personalized interpretations that evolve the language

Well apparently type class inference works just fine.

Not that there's anything wrong with that, considering 99% of C projects ended up being tons of structs + related functions.

Tell me why anyone would actually compare something that might be an integer or a string to TRUE.
Besides that book of autism, SICP, what are your favourite programming books, /g/?
>>51983723
"dicks" == 0 is true, too. So if you're testing for equality to 0 and use == just in case they made the field a string and put "0" in it, you'll get fucked. Stop trying to justify shitty coding practice through contrived examples.
>>51983622
>Well apparently type class inference works just fine.
except ML types not need to be grouped like Haskell type classes which makes ML programs more translatable and composable with outside programs because ML is more deeply based in theorem proving then lazy evaluation
>>51983730
composing programs
>>51983772
Okay, well, they need not be grouped, but that's why you have to use different operators for different types.

Damn, I never realised type juggling could be this evil. Are all weakly typed languages vulnerable to this kind of problems? Or has PHP gone too far? I mean, I understand casting string to float/int, but what happens here is casting string to expression: 0 * 10^a.

I have a question here.
I'd like to generate a mistake-based password in a text spelling a word I enter.
What I mean for example is a text with mistakes, and when you put the mistaken letters together, it spells a word.
Any idea where to start? This is a bit tricky.
We're going uncomfy slow again.
>>51984452

Give an example for a text with mistakes.
>>51984476
>hui.jpg

>>51984478
Yeah, this is a bit hard to explain. Basically it's an old way to put messages in text, mostly used during WW2.
Example:
I want to hide the word TREE in my text.
My text could be something like this:
" Dear John;
I'd like to have your atention for a second, because what I am about to say is really impotant. Excpt if you don't have any time this week, could you pleas go and visit mom this weekend? I'd appreciate that.
Yours Truly,
Sally "
You can also mistake letters like this: Heartakhe instead of Heartache for example.
It's just a bit hard to see how I can do this. The text would always be the same, but depending of the word, it would randomly put mistakes in the text to spell that word.
