Not much longer at all. Also notice in the picture the shortest word is three, meanwhile you made yours two.
>>53549787
Because the manga is designed for text to be written vertically, not horizontally, and it's a tradeoff between size, wordwrapping, and legibility. What does that have to do with programming though, other than your irrational hatred which you let everyone know about every thread.
Back on topic, why do programmers break their lines as X characters? Is using a scrollbar more work than it's worth? It seems to me that fancy typesetting and alignment of broken lines is a lot harder to maintain than simply letting the line go on as long as it needs to.
>>53549805

Trying to learn Spring for Java. Need a project to actually cement my knowledge and have something to put on my resume.
Of course all the Java projects on github are mostly for Android phones so the search isn't working out as I had hoped.
>>53549267
A script that can auto generate cover letters and also throw in keywords in certain places.
I find that I send so many cover letters that it's something worth automating.
Right now it just inserts the company name, location, and job title. I want it to also be able to include keywords like "I'm very comfortable working in X language with Y framework in a SCRUM/AGILE environment"
>>53549919
>all the Java projects on github are mostly for Android phones
Because that's all it's good for.
>>53550014
Yeah probably but most of the places i've seen that have asked for it are using it for some kind REST based web stuff or something.
I'm just trying to broaden out since it looks like a lot of enterprise java uses Spring but on the same token there's not a lot of enterprise java open source projects that I've found yet.
What if we made a game in Powershell?
Hullo, /dpt/
So I am trying to make a 3x3 puzzle in JavaScript. The rough setup would be:
onTileClick {
if top = blank space then move up;
else if left = blank space then move left;
and so on...
}
but the thing is I'm having problems on how to apply it to each particular tile when clicked. I'm running out of logic for this. I know the solution could be googled easly, but I learn better by squeezing spoilers little by little. Pic related
>>53550079
C and you got a deal.
>>53550090
either convert mouse coordinates to board coordinates on click or retrieve the tile id from the sender object
>>53550090
The easiest way to do this would be to make each tile it's own DOM element and attach onClick listeners to them individually.
>>53550093
The Powershell idea was mostly a joke. Like... let's make .NET hack.
I don't have any good ideas for games, and if I did, I'd be implementing them in C++14, not C.

someone please tell me there aren't unsolvable configuration in this and I'm just a retard

>>53550855
If you don't move pieces outside of the allowed moves then it will be solvable by simply reversing the moves.
>>53550855
There are unsolvable configurations.
In math terms, you can only do even permutations. That is, it's impossible to swap any 2 tiles.
>>53550855
wait no I solved it never mind
anyone know any more of those kinds of puzzles?

That's not how I wrote shuffling thoughchar[3][3] randomise(in char[3][3] input)

for (int y = 0; y < 3; y++)
for (int x = 0; x < 3; x++)
if (uniform(0, 2) == 1) // pick either randomly
swap(output[x][y], output[next(x)][y]);
else
swap(output[x][y], output[x][next(y)]);
return output;
}
int next(int x) { return ++x < 3 ? x : 0; }
if you number the grid
1 | 2 | 3
---------
4 | 5 | 6
---------
7 | 8 | 9
it could swap 2 and 8 for example, or 1 and 3

This will produce solvable states iff you do an even number of swaps.

Wait, no, you need an even number of swaps not involving the blank tile.
Hey /dpt/ give me some direction if you can. So Im in my final year of Int Relations at uni but I have no delusions of finding a job (working on a book thats irrelevant).

Urgh, its not that simple at all. Swapping the empty spot with an adjacent tile is an even permutation, swapping it with a tile that is a 2 squares away is an odd permutation.
I'm going to stop thinking about this now.

>>53551065
It's not that difficult a puzzle, and I've had to deal with a few similar puzzles back when I played Runescape, which used a 5x5 tile puzzle (although the method of solving it is pretty much the same any size). Basically, you solve all rows except the last two (which, since you already had the first row solved, was fine), then solve the last two piecewise (divide into left and right side). In the case of this one, it's just "get the 7 and 8 in the right spot, and the 9 will slide back into place."
As for my diet... I eat a dead animal every day. Today was meatballs and fried ramen.

The 'pure OO' answer is to restructure your code so you don't need to do this.

Explains some things.
Your code looks like you wrote Python and then added braces to things to fix the problems. You want to be adding braces to pretty much everything.for(div=2; div < p; ++div) {
if(p%div == 0){
printf("Not a prime number");
prime = 0;
break;

looks like c#, why not use a generic list instead of resizing the array?
also, why not store the alarm you're accessing temporarily, change the values and overwrite the index with your new object? Saves having to access the array in every step.

Isn't an array more lightweight and faster?

Not sure what exacly you mean, but that array is where all the data is stored while the program is running, it's not just there to populate the displaybox.
>>53554192
Absolutely, but it depends on what you want out of it.
>>53554282if (alarms[i].active == true) {
alarms[i].name = alarms[i].realname + " - ON";

>vector::size()
Obvious baseless assumption which happens to be wrong: it is clear that a vector must somehow know its own size, otherwise it can't implement half of its methods, so the complexity of the method can't be but constant. Thus,
the performance gain you're making by caching size here >>53556672
is negligible, and it is also a good source of bugs, in case you change the size of the vector while iterating, for example. Maybe you were asking for iterators? At least you should look into them. Finally, remember that if premature optimisation is bad, clueless premature optimisation is even worse.

Because the only person higher than a manager is the owner. Managers care about making as much $ in the shortest amount of time. Owners care about keeping the boat afloat by making sure there's a steady amount of cash flow and hauling in new clients.

Forgot C++ when you do C.
>>53558165
e.g. haskell code is ugly as fuck and even if some code is shorter it's not necessarily better
>>53558168
No, there's an annotation@tailrecin the language. If you use it, then compilation of the annotated method must fail if it could not be transformed into a loop.
>>53558165
Metaprogramming saves you from that.
TCO helps save you from rigid looping constructs and stack overflows in linear-recursive processes
>>53558103
Just make a 2D array and download valgrind because if you can't even figure this out the bugs you'll create will cause some fireworks.
>>53558183
but calling those methods to push_back something is slower than C. that's why i wanted to know
>>53558211
why not write a loop in the first place fucking FAG

}
>>53558178
It transforms methods marked@tailrecto while loops or fails to compile them.
For anything non-trivial, you need to use a trampoline, sadly.
I wouldn't hold my breath waiting for JVM support for it.
>>53558222
>but calling those methods to push_back something is slower than C. that's why i wanted to know
Whoever told you that is a retard. C++ is zero-overhead, and often faster than C due to a stronger type system (no void* everywhere).

Easier to get wrong.
>>53558222

>>53558237
Eh, I'm a CL fag
But I'd hop right the fuck on ABCL for that sweet java lib interop once that gets fixed (though, I'm just as comfortable using LOOP proper as I am taking advantage of recursion, so I may as well stop being a bitch about it)
Also, Scala looks like a pretty sweet non-lisp.

>and it is also a good source of bugs, in case you change the size of the vector while iterating, for example.
Changing the size of a vector (or any container) while you're iterating over it is a recipe for disaster because it invalidates all iterators.

>>53558306
Yeah, despite its flaws, Scala is a good language. You can get really far with it in terms of what abstractions you can express, but you have to be really careful and disciplined in places where you just wouldn't have to in Haskell because the language just wouldn't let you get it wrong.
I'd say it and Clojure are the top 2 languages on the JVM today. It'll be interesting to see how Frege (a Haskell implementation on the JVM) matures.

That's the problem, Einstein.
When every sensible language has a print*() function, Java has some gratuitously verbose System.out.print*(), just for the pleasure of taking things too far.
You will never need two levels of namespaces for the print functions. There is not possible clash, and this is just pointless mastubartion.
This is not useful. This is noise. Boilerplate.
>>53558500
>Metaprogramming has its own problems, being harder to debug and reason about.
Not as hard as you'd think, but Metaprogramming is a tool best used sparingly and with rigerous testing, even in places where it's relatively easy to do.

If you think Java is a bad programming language you are a shit programmer end of discussion it takes real intelligence to program well in Java

tbf, `System` encapsulates environmental settings, `out` is an Object pointing to a PrintStream, and `println` is a method of that object. In this instance it's not unreasonable.

Meta programming makes debugging easier since you can hook into the compilation process for better diagnostics (i.e domain specific error messages, not just generic exceptions).
And similarly it makes profiling easier since you can emit markers and meta data when compiling.
External debuggers and profilers do these kinds of operations for you, but they operate on binary code, or possible generic debug formats, with meta programming directly supported by the language you can easily make your own debug and profiling directives.

Work on my javascript chops, and I like the idea of not downloading anything and it already working on most platforms. I started using three.js, but there were some things I wanted to do that I didn't really know how to do so I'm just learning this from the beginning. I'm learning opengl in the process, so I can apply what I'm learning here to any other platform that supports that. Also no compiling.
>>53558884
First I created a base class for all game objects that has the objects position and rotation stuff. Then I created a geometry object that holds the vertices/colors/indices. Another class is just the relationship between a base object and a geometry object. You create a scene that has an array of all your objects, and you iterate over them during your render call. You have to use matrix stacks so you don't recalculate the camera stuff for each object. Really that just means you save your camera's translation/rotation matrix so you can reuse it for each of your objects. WebGL is kinda behind the times, but I'm having fun with it.
