Longer names aren't essentially more readable, if names are too long, the flow of the code is obscured.
Name length varies depending on context: If declaration and usage are close, meaning the scope is small, a shorter name is better, especially if the meaning of the variable is immediately obvious in the given context (maybe because a type is attached, the variable is something obvious like "i" or "n" or the respective construct adds meaning, like for each v in values).
Also, another factor that should be considered is how often a name is expected to be used. If something is used a lot, even in a large scope, then a shorter name is better as well, because it can be expected that the reader likely knows the name (math instead of mathematics, fmt instead of formatting, str instead of strings, ...).
Also, occasionally longer names should be chosen when name collisions may be an issue (occasionally situations arise where you're stealing names from your user).

C++ newbie here, learnt what the command "system" does so I decided to make a program to check if I'm connected to the internet but when I execute it, it eats up all my ram, my cpu power and doesn't close by any means(alt f4, X button, task manager). It also creates a billion processes. I learnt that "system" just writes stuff to cmd. Here is the code;
#include <iostream>
using namespace std;
main ()
{
system("ping google.com");
system("pause");
return 0;
}
I know I didn't use any std commands, I was going to but I tried executing this primary stage of the program to see if it works and all hell broke loose. What the fuck is happening?

My guess: your program is called "ping" and the system call invokes it instead of the system ping, so it creates an infinite loop of doom. BTW this wouldn't have happened if you were running an actual operating system.
>>53811365
Is your program's binary named "ping" or "ping.exe" by chance?
Because except infinite recursion, there's no reason this shouldn't work.
And don't fucking use system. Anything but system.
>>53811410
it's named ping.exe. I assume there is already a program in windows OS named like that and that's the reason this is happening?

I have a noob question.
So I have the game loops seen in the picture.
>The main loop creates the Char and Map objects
>The Battle Prep loop instantiates the chars and generates a map
>Combat loop does movement, combat, etc.
So my question is this: What's the best way to pass the reference of the map and chars? Simply adding them as a parameter would just end up making the code extremely unwieldy and it wouldn't really be a good way to make any sort of concurrence.
Can I make some sort of shared memory pool and then simply mutex my way out of it?

>>53811423
There's your problem. When you do system("ping google.com") it finds your program "ping.exe", not the system ping, because system() is crap.
You made a program that opens itself, so it'll keep openning itself until your computer slows down to a crawl.

lmao, I remember writing a .bat to .exe compiler waaay back in the day by doing this:

Then compiling it with g++ or whatever compiler i had on windows.

Enjoy your blatant security vulnerabilities and nonportable behavior, I guess.
>>53811423
No, it would also fuck up if you called your program "fgwza" and system'd on "fgwza". Whether there is another program with the same name is irrelevant. The problem is that the name you're invoking gets looked up in the current directory before being searched amongst the commands of the OS. This is a design flaw of windows btw.
>>53811445
Then you come into one of these bomb directories where there's a dir.bat that contains "format c:", and your program fucks the user over, even though they haven't committed the mistake themselves and you should have been doing some system calls instead.

And if this library is statically linked, then you have to compromise the kernel first.

How? Because Java forces you to pass objects rather than first-class functions (which don't exist) to threads? Maybe, but it still means you have to instanciate them, so I'd go for putting Map and Char into a separate Data object which you can pass around, extend, or have multiple instances of.

When a lot of people work in one repo it's really confusing with all the merges you get. If there are several commits to pull before you push, you have to commit also a merge. TFS does not do that - you have to merge changes before you commit and you get a nice and clean commit with your changes only.
Also having tasks in TFS and directly linking changesets to them makes understanding logic changes really easy - requirements are one click away.

Undo is revert, HEAD means current, and ^ means previous. So "git revert HEAD^" goes back one commit before current.

No, you just need to rebase your changes instead of merging. You're looking for git rebase, or just "git pull -r" to rebase when you're pulling.
>Also having tasks in TFS and directly linking changesets to them makes understanding logic changes really easy - requirements are one click away.

How so? On the contrary, I would argue that Git has a nicer model that the rest, because it is focused on workdir states, which is what you put in and want to get back. I believe that earlier vcs where focused on deltas because of a lack of abstraction over the way the data is deduplicated. what requires such a deep understanding, and what makes you call the representation "delta"?
>Every time I want to do something mildly complex, like undo my last commit, I have to look it up.
How could "commit --amend" be more rememberable? Wait no, I got it, you mean "reset" etc. Yes, you need to understand the "three kind of trees" as they call it on git-scm. That's not so bad I would say. Also resetting stuff this way is bad practice because it makes remote histories deviate, so "ugliness is a feature" it this case.

The order in which the breaks occur can affect the total amount of time used. For example, suppose that the programmer wants to break a 20-character string after characters 2, 8, and 10 (numbering the characters in ascending order from the left-hand end, starting from 1). If she programs the breaks to occur in left-to-right order, then the first break costs 20 time units, the second break costs 18 time units (breaking the string from characters 3 to 20 at character 8), and the third break costs 12 time units, totaling 50 time units. If she programs the breaks to occur in right-to-left order, however, then the first break costs 20 time units, the second break costs 10 time units, and the third break costs 8 time units, totaling 38 time units. In yet another order, she could break first at 8 (costing 20), then break the left piece at 2 (costing 8), and finally the right piece at 10 (costing 12), for a total cost of 40.
>Design an algorithm that, given the numbers of characters after which to break, determines a least-cost way to sequence those breaks. More formally, given a string S with n characters and an array L[1..m] containing the break points, compute the lowest cost for a sequence of breaks, along with a sequence of breaks that achieves this cost.
me and my homework group sat around for an hour just on this one single problem and we didn't make any progress at all. please help

That's quite possibly true. It doesn't explain his behaviour at all however. Most OSS projects manage to be led by someone who isn't a rageaholic. I can't think of a single other programmer who is as notoriously angry as Linus who manages a project.

I disagree. Sure that definitely USED to be true but newcomers who want to write websites just don't gravitate to PHP anymore.
>>53812182
Wow, I'm glad I'm self-taught.
>>53812182
The premise is so awful I would refuse to work on this. No sane language would copy 20 characters THEN discard the 18 last. You just allocate space for two chars and copy them.
>>53812182
make the string immutable and compute offsets + lengths
>>53812210
Judging from stack overflow, that is wrong.
Just think about it, PHP is pretty much a second native language in India.

How is it not really easy? Can't you try every permutation of L, compute the number of time units it will take and keep the best result? Brute-force isn't always right, but here it seems right, no?
>>53812232
Isn't the content of the string irrelevant anyway? We just need the length

>fucking retarded largely for that reason
the difference being that people, on average, seem to be much dumber here than on LKML and they don't have a common project to work on.
i agree with >>53812091. he's not unreasonable in criticism, albeit refreshing and perhaps often overly clear in tone, even though a lot of his hyperbole is also wrongly portrayed as mean spirit.

It looks like an algorithm problem, not a real world problem. They probably don't want performance or common sense, just the "right" answer.

the section we're on is dynamic programming so i assumed we were supposed to use that for the question, but it doesn't look like it specifies you have to use dynamic programming. so that may be what we end up having to do. my brain just explodes when i try to read the question and make a dynamic programming solution

>>53812294
cost(breakpoints, i, j) computes what the cost is for jus the section between i and j, recursing if necessary. Base case: there are no breakpoints between i and j, so not splitting it up obviously costs 0. make one (i,j) cache per breakpoints array for this function, done.
Maybe you need to keep only the values that will be useful again in the cache?

It's a buzzword, it should be called something else, I agree, but at least it's not a meme. Also lazy evaluation plays well with so-called "dynamic" programming patterns.

It's not about just caring about shit. I'll get mad as fuck at people if they are making the quality of the project suffer because they are being lazy or too close minded to consider better solutions. Linus blows up over tiny shit where there isn't a clear answer. Imagine suggesting a way to make a project you are working on better to a colleague, and then him getting fucking pissed as shit at you for being "wrong" and "wanting to ruin the project", is that helpful? It's as easy to say "We're not doing that because of reason X" and let him either accept that, suggest why that might not be a good reason or improve his suggestion. The media tends to post Linus's entire email threads where he blows a fuse at someone, and I've read a few of these. It's not misrepresentation. He get's mad about shit that totally does not warrant it.
>overly clear in tone
Saying everything loud and angry does not make you any clearer. If it did, every project manager everywhere would aspire to act like Linus. They don't because this obviously is not a good way of working with people, it's just a way for people with anger management problems to get some relief.

>>53812728
in C the more _t's and underscores you have before variable names, the faster it goes.
>>53812728
it's mostly not needed but you could change the type to e.g. int32_t at the typedef and everything that uses buffer_t would just work
>>53812728
The only reason that would make sense is if buffer_t is changed depending on platform, etc. to something that isn't int.
Otherwise it's bad practice.
>>53812728
i use typedefs only for structs and other compound types.
>>53812728
It sounds like buffer_t is a buffer rather than an element of the buffer, the purpose of this is clearly to confuse people.
>C fags need to litter their code with typedef
The only thing you should ever be using typedef for are opaque, or otherwise implementation-specific, types.
>>53812728
The other rule it's breaking is naming itself name_here_t. Any _t names are reserved by POSIX yet everyone breaks that rule.
>>53812728
I would think buffer_t is a complete buffer object and not just a fucking int, who writes code like this?
>>53812836

>Any _t names are reserved by POSIX yet everyone breaks that rule.
