why?
First for please send help.
Doing my first ever proper project, I'm working in VB because I'm utterly useless.
I need to create an array, dictionary or iList of some sort that stores a single string from a listbox on the left side and then any number of strings from the left side, and have them be readable from the strings acquired from the left listbox.
I understand the basic concept but actual implementation is making my brain melt.
>>51653958
Sorry but doing it in VB actually is a huge barrier to getting help here.
>>51653977
True, I understand the syntax but I'm not sure of the concept that would allow me to input the first string into the dictionary from the left listbox and then have any possible number of the ones added after it.
I know I'd just do dictionary.add([stringfromleft],[stringfromright], [stringfromright], [stringfromright], ) but I don't know how I would go about having the string from right being run in a loop because it'd add multiple entries to the dictionary which isn't helpful.
One of my classes required me to do two projects on an Arduino. For one of them I did a super basic calculator. Each led is a digit 0-9 (red are 0-4, yellow are 5-9), and depending on what the answer is, the corresponding led will flash i.e. 41 will flash led 4 and led 1.
The first answer you see in the Webm is for 9 + 2 and the second is for 8 * 8. It handles addition, multiplication, subtraction and division. Parentheses can also be used.
Nothing major to brag about, but it was nice getting done. Here's the code
http://pastebin.com
>>51653977
>>51654008
I'll also want to store a (possibly) large amount of text from a textbox underneath in the last value of the dictionary so I can use it also.
>>51654035
And here's the actual pastebin I meant to post
http://pastebin.com/wpx9rxZj
>>51654040
>>51653977
>>51654008
Okay let me try again, how would I go about declaring a variable and using a string from elsewhere as it's name.
Say I called listbox.SelectedItem and wanted to use whatever that value was as the name of my variable.
>>51654118
Using a reflection.
Where can I learn how to plan and prepare for a large programming project, like with a notebook and pen? I really want to do something but the amount of work I need to put into it is overwhelming to me. Would mythical man month/no silver bullet be a useful read?
Is it possible to use variadic functions in a shared library?
how good is code:blocks, I have windows.
>>51654147
I'm so sorry.
>>51654146
and if it is, are they as "stable" as other c functions? As in, would a different build of the same lib still link correctly?
>>51654147
Use a text editor instead, and write your own makefiles

Look at the samples and play around with Dictionary first, because you don't understand the syntax. I think what you want in VB terms is a Dictionary(Of String, List(Of String)), a dictionary with a String as the key and a List of Strings as the values.
since theres a new thread
this might be more sys admin related but what's the best way to remotely execute a program on another computer, i'm trying to get my raspberry pi to open programs on my computer
what i've done so far is set up a ssh server on my windows machine and i've tried using psexec which works mostly well for the first part, but 1: i have to make myself admin to launch programs in the current user session and 2: authenticating over the network takes like 5 extra seconds and is really slow
should i try to figure out if i've done something wrong with psexec or do you guys know of better ways to do it
>>51654165
>>51654185
I guess I could install linux, is it better than windows for programming?
>>51654202
Hell yeah
>>51654204
i need it running in my current user session, running it straight from the ssh server runs it in the background
>>51654202
Depends if you want to program for windows or not. I just use mingw and notepad++ on windows.
>>51654217
whats a good distro for an old laptop I won't have to bullshit with? linux mint?
>>51654256
Yeah, Linux Mint is a quick install and good for learning to use Linux
>>51653958
Can there be duplicate strings on the left side? If so, you won't want to use a Dictionary, you should instead use a 2D List (a list of lists)
>>51654197
I got the dictionary thing down, I just have no idea how I add an inconsistent number of strings from a listbox into it, whilst only adding the one string from another listbox to use as the key.
Making a for loop won't cut it because it'll just create another dictionary each time.
>>51654338
Nope, I want to display the one from the left, proceeded by all the ones they selected from the right, and give them an option to clear that entry to do it again, but attempting to create another entry whilst one is still displayed will throw an error asking them to clear the one they already have.
>>51653936
still looks like a samefag. could be using a proxy. it's a shill job regardless
>>51654387
>Making a for loop won't cut it because it'll just create another dictionary each time.
What?
>>51654328
what about debian?
>>51654413
There's no way that multiple people like superior languages! It must be a single person posting through a proxy!
>>51654431
Yep I literally just read my post again.
I assume I can have multiple dictionary entries that all use the same string from the left as a key. Which makes a lot more sense. I got it now.
>>51654453
hardly anyone uses D to even know whether or not to like it.
>>51654387
Like I said, make it a Dictionary(Of String, List(Of String)). Then you'd Add each of the keys with a New List(Of String) for the value, and then add any number of strings to the list corresponding with the key.
>>51654460
You cannot, the Dictionary connects one key to one value. However, you can make that value contain multiple items, for example by making it a List.

How's my JavaFX Disk Usage Analyzer?
It's WinDirStat made multi-plat, without file manip (thats what you have terminal and filemanagers for), works with network drives that you have a relative path to from the system, no IP/UDP accessed network drives.
Are any of these worth reading?
>>51654529
I didn't say either of those things. I said:
"hardly anyone uses D to even know whether or not to like it."
Which is perfectly correct.

>>51654516
Isn't the 2nd value the key? Or is the key literally whatever you want it to be, as long as it's consistent?
What is the best statically typed functional language?
>>51654621
The key is whatever string you want it to be, the value is a list that contains a set of strings. So the dictionary creates a one-to-one relationship between a string and a list then the list contains multiple strings.
>>51654516
>>51654621
Can't convert selected items to List(OfString) I can't think of a way to make the thing accept multiple strings without a loop.

Debian or Ubuntu are the only distros worth thinking about. I use Ubuntu because it just works and I'm NOT a trendy faggot who thinks you should never use ubuntu (and I have a newer computer). Debian is okay for old servers that never should be updated. Do an ubuntu minimal install if you want new software on an old computer.
>>51654665
use a loop. You shouldn't be creating the Dictionary inside the loop, only adding to it or to one of the values for a key it contains.
>>51654641
Haskell.
My professor has given me the go-ahead to use pre-computed primes for my assignment, noting that in many cryptographic implementations, it is common to use primes that are essentially safe and verified. Also, I did point out that while the assignment specifies the must generate the prime numbers ourselves, it does not specify that they must generate them at the same time as the other parts of the public and private keys. He tells me I'd make a good lawyer, were I not studying computer science.
So I guess... I now have a working implementation of ElGamal using the discrete logarithm problem, that can exchange an AES key and send messages back and forth between two processes, all in a couple hundred lines of Ruby.
Now all I need to do is modify the program to work for elliptic curves instead.
How's everyone else's work?

Let us put it like this: libc is available as a shared library, and printf is a part of libc. Because printf is a variadic function, therefore we can conclude that variadic functions may appear in shared libraries.
As for linking complications... there shouldn't be any. Register and stack calling conventions should be the same for a platform regardless of which compiler one is using, and regardless of whether the amount of arguments is fixed or variable.

Working through nand2tetris and figuring out how to implement a multiplexer using only And, Or, Xor, Nand and Not gates
I'm probably retarded, but given a point in 2-space, I draw a square around that point with a sides 1 unit away. How do I find the length of the diagonals?
Say the point is at (5,5), the mid points of each edge are (5.5,5), (4.5,5), (5,4.5) and (5,5.5), but what are the corners?
>>51655143
The diagonals are the hypotenuse of the resulting triangle.
The length of the triangle is 2 units, so is the height.
Using pythagoras' theorem:
H^2 = 2^2 + 2^2
H^2 = 4 + 4
H = 2.83

Please explain. C# and VB (because they're both .NET) have the greatest error messages in the world.
What are you doing?

If you don't use Arch or some other gay do-everything-yourself distro you may as well just use windows. or just use windows regardless
>>51654146
Yes. Note that on Win32, variadic functions always use the cdecl calling convention, whereas functions exported from DLLs normally use stdcall (which can't handle variadic functions).
How do i do the parts in red? Java btw, thanks.

i don't use linux. i think using something like ubuntu is completely pointless when you can just use windows 7 instead. i don't see any significant benefit to using ubuntu over windows. if you're going to use a hobbyist OS you may as well use something that is targeted to hobbyists rather than normies.

Because it seemed like the right choice at the time, simple and easy to create nice looking GUIs which was kinda important.
I assume .NET, I just downloaded Visual Studio 2015, booted it up in VB mode and got to work.
Turns out it's an absolute fucking mess and so many people posting solutions that make absolutely no sense, in a different language entirely or for VBA which I can't use either.
Now I've sunk about 10 hours into it and got nothing to show for it for it.

FileReader API.
If the browser supports it, an <input type="file"> element will have a .files[] property containing the list of selected files. Use FileReader.readAsArrayBuffer() on one of them to obtain the file's contents.
If the browser doesn't support FileReader, you're out of luck.

You made a bad bad bad decision.
Use C# instead. VB.NET only ONLY exists to pull VB classic programmers into the .NET ecosystem easier. It's not a nice language for .NET development at all.
Sounds like it will be easier for you to re do the whole thing in C#.

>shit's fun as hell to setup
yeah maybe the first time, afterwards you realize that not having an installer available is a pain in the ass
>>51655743
the data isn't three-dimensional. you could say it has two dimensions but not three. ID, class group and average grade is one dimension and then the students make up the other dimension. but really you're over-complicating it. the question wants you to have a bunch of Student objects in a collection such as an ArrayList which is one-dimensional.

I hope I can port something over instead of having to start entirely from scratch, but maybe a fresh start might yield better results anyway.
>>51655743
> well yeah but it can be represented as three.
Maybe, but that would be dumb (the array will be extremely sparse). I 1-D array of tuples or a 2-D (Nx3) array would make more sense.
> how would you math out a three dimensional array as one anyway?
a3[i][j][k] = a1[(i*n_j + j)*n_k+k]
where n_j and n_k are the number of elements in the 2nd and 3rd dimensions.
Essentially, a[i] starts at
a + i*sizeof(a[0])
And the size of an N-element array is N times the size of each element.
>>51655812
porting will be fine i'd say. The reason why you're having trouble understanding why your VB isn;t working right, should become clear as you port it to C#.
I think you can get it converted automatically. Which might makes things easier for you.

Why use two OSes without seemless integration? I've been using MSYS2. It's a million times less painful that going between Windows and Debian.

I might hve to recommend Java if you reaalllly want the gui.
>>51655880
>Why use two OSes without seemless integration?
Because I haven't got a need for seamless integration? Whenever I need something to work elsewhere, I just grab the code and recompile under Loonix.
>I hate Windows
I really don't mind Windows. Often time it doesn't have the tools I need (Valgrind, pls!), but it's not as bad as some people make it out to be.
Also, video gaymes.
>>51655798
There's no limitation on size. If you want to impose one, you can check the size of the file via the .size property on the element of the file list before you start reading it.
>>51655931
Still no Valgrind on Windows, luckily MSYS and mingw cover most other software I care about.
Windows is slow (on a hard disk especially), very buggy, very power consuming on a laptop (my little Acer laptop gets 4hr under W7 and 9hr under CB), is a piss-poor development environment unless you are using the tools MS wants you to use, and the "I know better than you" shit MS pulls (especially on W10) is obnoxious. It's only saving grace IMO (and it's not even by its own merit) is that I can play video games on it.
As soon as I can get decent graphics drivers for Linux and can run a minimal W7 VM and play my games on that I'm never looking back.
>>51656090
>Still no Valgrind on Windows

>>51656115
I've been using Atmel Studio, which is VS based with a avr-gcc backend, and I don't like how everything is packed up into 'projects' which I assume is a VS thing. It makes it shitty for git (merge conflicts out the ass because a fucking recompile) and it's impossible to edit multiple projects at once, although maybe VS has that feature.
What's so great about C# in comparison to other languages? I've just looked at the wiki and it seems like Java-MS with some influences from VisualC++. I mainly stick to LuaJIT and the massive library I've built up with it. Been thinking about putting it together into a formal language with MetaLua and some C libraries.
>>51656090
>Windows is slow (on a hard disk especially), very buggy, very power consuming on a laptop
Why do people actually believe this pig slop? None of this is true at all. Linux is nice in lots of ways, but being faster, less buggy and less power consuming as a desktop environment? The exact opposite it true. Though all those could arguably be true for a headless server environment.
>As soon as I can get decent graphics drivers for Linux
People have been waiting for this since the 90's. GPU manufactures are only going to bother to optimise the drivers for the OS's most of their customers run. Don't expect linux to be one of them for a long time.
In any case, using windows for VS alone is worth while. Pretty much what I do.

>>51656326
>I've just looked at the wiki and it seems like Java-MS with some influences from VisualC++.
It pretty much is Java-MS with C++ gizmos attached to it. That's what makes it great.
Imagine if Java was enjoyable to program in.
That's C#.
>>51656368
>Why do people actually believe this pig slop?
Because it's true. I've been using it since I was ??? Windows is markedly less reactive than a Linux distro, especially when you aren't using an SSD. The difference becomes negligible then. I run into programs freezing under Windows that don't under Linux distros and overall more freezes and crashes under WIndows. I've never seen FF freeze or crash under Debian. And yes, power consumption is important for a laptop, thank you for ignoring that bit.
>using windows for VS alone is worth while. Pretty much what I do.
You didn't have to tell me. I knew.

>>51656434
>'ve been using it since I was ??? Windows is markedly less reactive than a Linux distro
>markedly
Markedly by what? placebo? Do you have any kind of metric anywhere that makes this up? Should be easy to prove. The GUI on linux is insanely bloated compared to windows. Everything sits on top of X, which a monster. Utterly unsuited to its task on modern systems and introduces measurable lag. Read about the problems with X sometime. Wayland is meant to fix this, but hardly anyone is supporting that properly yet. Not to mention less optimised or functional GPU drivers make things even slower on top of that.
>And yes, power consumption is important for a laptop, thank you for ignoring that bit.
I didn't, i mentioned it specifically. Learn to read. Linux is terrible for power management because the UI rendering frameworks are so fucking bloated, everything takes way more fucking cycles. And again, shitty drivers tend to be less power optimised. Every benchmark I've seen on this shows linux being much worse than windows on any laptop i've seen them both tested on.

You sure you know enough to be arguing the point?
Of course I don't have empirical data, I presume you have none that proves Windows is faster, either. This is just opinion.
X is a monster, but still quicker than Windows' system (which I presume is every bit as much of a monster, it's just hidden from you), still more power efficient than Windows' system (4hrs vs 9hrs, I've actually run a battery test to completion, i.e. it's not false advertizement).

You say that as if it would be hard to find. The issues with X regarding lag and tearing are very well established. It's not an opinion, I just bothered to educate myself on both systems.
>but still quicker than Windows' system
Based on what? because it "feels" faster? Windows has had proper windows compositing since vista, which linux is still waiting to get.
>still more power efficient than Windows' system (4hrs vs 9hrs, I've actually run a battery test to completion, i.e. it's not false advertisement).
It's not advertised at all. I've read multiple benchmarks on this over the years and linux is always way behind due to the reason I mentioned. Have you read benchmarks to the contrary anywhere?

Slow down there, he is specifically talking about high level languages, not all languages. Read that reply thread again.

pffffttttthahaha, that's rich. You don't know shit about Windows' subsystems or their performance. You've also never heard of a compositor.

Yeah? Show me a system that is not noticeably faster that is actually faster.
>I've read multiple benchmarks on this over the years
I also don't give a damn about benchmarks from years ago. I spent a couple hours time editing config files on a modern machine, most benchmarks compare OOTB. Linux gives you the opportunity to better the battery life, Windows gives you next to nothing.

I am sure that Windows' compositor is cobbled together with numerous hacks to keep it shiny, but it is a faster 'experience' for some reason than X.
As some other guy said I do hope Wayland catches on quickly.

This is a myth that keeps floating around that you can judge the efficiency of a programming language by the size of its runtime spread mainly by people who have nothing better to do that look at the size of their hello world. Lisp has good reasons for having a large runtime, mainly it uses a lot of compile time functionality at runtime. The size of the runtime has no effect on the the memory efficiency of the language. The runtime does not grow, its permanently fixed in size. Anyone who complains about language runtimes are fizzbuzzers

Substantiate your claim that Windows is faster then, oh Mr. man of science. I've used both for many years and I know Windows is laggy and slow. Show me evidence it isn't and I'll reinstall Windows over again and do what I need to make it not so, because I'm obviously doing something wrong.

I have an executor service with a fixed thread pool I submit runnable tasks to. Currently I'm doing busy-waiting if a certain condition is met (when there are no tasks available but there are threads running) by polling in a while loop.
Instead in that situation I want the main thread to wait till the end of any of the run() methods in the current working threads since that is when new tasks may be available.
How do I do that? I tried using a countdown latch but I fucked it up horribly.
I apologize if this isn't the right area to ask. I am trying to learn C. I am learning about boolean operators. I want to make it so I plug in a number to go to a specific example, and it simply outputs the answer of my selection. Here is my code as of right now.#include <stdio.h>
int main()
{
/*NOT operator will indicate that the option you want isn't the one written. NOT is written as !. NOT is evaluated before all other operators.*/
/*AND operator will indicate that something is true only if both things are true. AND is written as &&. AND is evaluated before OR.*/
/*OR operator will return a true if either of the statements are true. OR is written as || (pipe).*/
int choice;
printf ("Which example would you like to read? Your options are 1, 2, and 3. ");
scanf ("%d", &choice);
if (choice = 1) {
!( 1 || 0 );
}
if (choice = 2) {
!( 1 || 1 && 0 );
}
if (choice = 3) {
!( ( 1 || 0 ) && 0 );
}
return 0;
}
I was trying to use printf for the boolean examples which gave errors on compilation, removing printf doesn't make any errors but nothing is output (assuming of course these examples should output a 0 for false and a 1 for true). What do?
>>51658115

single = is assignment operator not comparison. use == if you want to compare two values.
What you're actually doing if choice == a number is pretty much nonsense. I actually have no idea what the fuck you think it's doing but
NOT(1 or 0) is just an expression that would always evaluate to 0. It's like saying Invert(true or false) which is Invert(true) which is (false).
But you're not doing anything with the value, you're just stating it for no reason or side effect.
Once you've managed to get the if statement thing working you should look up how to do a switch because a switch does exactly this thing.
>>51658115
Here's an idea, there's probably a better way to do this with printf, but you could write a function:
void print_bool(int b) {
if (b) {
printf("true\n")
} else {
printf("false\n");
}
return;
}
and then pass your boolean expression as an argument to print_bool inside your conditionals like so:
print_bool(!(1 || 0));

I'm a programming newfag working in Python and I'm making some shitty guessing game where you see three shapes, they get mixed up, and you have to click the one that you think has the ball under it. You know the one, people usually play it with cups.
Anyway I made two buttons, one is a square and one is a circle. The third I figured would be a triangle but then I ran into an issue. How do you tell if a point is inside a triangle? For a square it's just "is this point greater than X1 and Y1 and less than X2 and Y2?" For a circle it's just "is this point further than (radius) from the centerpoint of the circle?" For a triangle though, the bounds are sloped lines not contiguous with any graph lines. I know this might be a stupid question, but do any of you guys have experience with this? I'm tempted to just do some geometry and strongarm it but I feel like there's probably something more elegant that I'm overlooking.
>>51658555

Being a language ideologue will indeed inhibit your development as a programmer, but there is a _big_ difference between smashing out some shitty code and being a career developer in that language (no matter how similar it may be to other languages). When you've internalised a language's community, tools, ecosystem, and environment, I think it's fair to call yourself a "C# guy" or whatever (I know this goes beyond just the language but, practically, languages don't exist in a vacuum).

I only know English, so I don't even know if my example is proper or not, but say you want to print out an object and what colour it is. Something like "red balloon".
So you have something likestd::string thing = "balloon";
std::string colour = "red";
std::cout << colour << " " << thing << std::endl;
Now you want to internationalise your code. You start with French. You'll actually be picking which strings to print at runtime, but you'll basically havestd::string thing = "ballon";
std::string colour = "rouge";
std::cout << colour << " " << thing << std::endl;
But that gives the wrong answer. In French, it's supposed to be "ballon rouge".
To fix it, you'll need to add conditionals or something stupid to fix it, and that would be very complicated, very fast.
You could be less retarded and use format strings (like every other language, besides C++).#include <stdio.h>
int main()
{
char *thing = "balloon";
char *colour = "red";
char *format = "%s %s\n";
printf(format, colour, thing);
}#include <stdio.h>
int main()
{
char *thing = "ballon";
char *colour = "rouge";
char *format = "%2$s %1$s\n"; // This is POSIX compliant
printf(format, colour, thing);
}

humans can perceive latency much better than memers will have you believe. extrapolating 2 ms past the start of the current frame being rendered makes the input feel ridic responsive but it introduces occasional extrapolation errors which are undesirable. moving the target time back by 2-4 ms cleans up the input a ton because we're extrapolating less into the future, but i won't move it back by even 2 ms because of how slow it feels compared to 0 ms or +2 ms. targeting the start of the current frame being rendered seems like the optimal choice.

to be fair, most of the early users either came from functional languages (in order to find a safer C that's more to their tastes) or, being involved in the early compiler creation process, were introduced to functional languages. but yeah i do keep seeing a lot of idiots try to force it into becoming a functional language where it's not really meant to be one. like last week i saw maybe 3 or 4 parser combinator libraries for Rust pop up on HN.
i just can't wait until Rust becomes the exact same as C is now so all the C faggots can start moving to Rust and give it a large community and a large set of libraries (plus this would probably kill off all the SJW bullshit).

>like last week i saw maybe 3 or 4 parser combinator libraries for Rust pop up on HN.
What exactly is bad about this? Parser combinators aren't married to the functional paradigm.
>>51659782
the idea behind parser combinators is literally based on higher order functions. with Rust you're not supposed to use closures everywhere (as they're usually way slower than alternative solutions and they tend to be awkward to use in general at a low-level) and high-level abstractions are not one of the ideas the language is meant to promote. parser combinators might even be a better idea in a language like C# which, even though it's more like conventional imperative languages than Rust, is heavy on abstraction and supports closures, higher order functions, etc. very well.
if you're trying to use Rust to write software from a high-level standpoint then you're not using the right language for the task.
Is there a good guide for writing a dead simple compiler from scratch? Nearly everything I've found is

Parser combinators aren't necessarily higher-order functions. What if a parser was just a string of bytecode, or something like that?
In any case, I also don't see how closures are somehow some ultra-high-level-and-slow construct. All a closure is is a function pointer and the data you captured.

That's silly.

Use a functional language. With parser combinators.
>>51659882
depends what language you're using and what language you're implementing. the best book i've found for programming language implementation is Essentials of Programming Languages because it pretty much delves into every possible idea you might want to implement into your language and the code used in it is all very readable (even if you're not familiar with Lisp/Scheme), but the main down-side of it is that it focuses entirely on interpreters and barely even talks about compilers.
most people say go with The Dragon Book if you're using C or C++ or some language like that, but i never really found it to be as good as people said. i like the LLVM Kaleidoscope tutorials a lot, but they kind of just dive straight into the code immediately and don't explain everything super in depth.

This has pretty much been my strategy so far. I'm starting to get a hang of the Cocoa drawing API now though.
Thanks 4 the advice

The classic compiler tutorial is "Lets Build a Compiler", the text is also the source code, its was written in Turbo Pascal, it can still be compiled in Free Pascal

No, thanks for the tip.
filtering stuff from list,
Currently i have a list of object that looks like this, and I want to eliminate duplicate objects.
my expected result should be like this
UserList.java
String username
List<String> tagId;
List<String> roleTitle
