Happy new year, OP.

Still working on WAMPVOIP.

Happy new year, /g/.

do i really need a cloud service for some very basic/minimal app backend that's basically just users uploading and downloading a small number of tiny files? a normal web host plan with ASP.NET should be fine for that, no?

the horror stories where people on shared hosting plans got shut down by their hosts all seem to be when they did some retardedly huge tasks like mass email sendouts and doing gorillions of database requests for each user

im only 20 iq pts behind a man (einstein) who debunked the majority of physics by thinking about trains. And seeing as physics deals with true complexity and other science do not, its even more reasonable for a 140 to be able to trash your kind than it was for a 160 to trash physics ;)
if ur iq was above 140 u wouldnt be as butthurt about the concept of a 140 hyp grad lurking this beta barn..
so the logical conclusion is that ur iq is lower than 140 (possibly much lower)
if you met me in real life you would instantly be blown into a world where all that mattered was getting me to acknowledge your existence and even hopefully be your friend... But i would probably find you to be a desperately uninteresting person and want you to exit my awareness as fast as possible.
the fact that i dont lie about my iq is what gives me the edge necessary to call you an inferior little girl who couldnt understand basic physics, and BE RIGHT ABOUT IT.
honestly if i woke up one morning and for some reason my thinking capacity had devolved to your level, it would take me less than 5 min to run to the kitchen and slit my throat...
maybe your going to tell me u work at goldman..
but ud still be way inferior, as is anybody who projects their iq to be higher than it is..

I have a gcc/g++ from mingw, or I can log in to my linux and do all this from there and we have the whole set. What say ye? I can code in a few languages out of compiler, though, so maybe we can hop on that. I'll even play down to some javascript considering I know none.

But in case you were serious, I used to use this when I couldn't get a library for serious hashing:

int hash(char *str)
{
        int len = strlen(str);
        int hash = 0;
        for(int i = 0; i < len; i++)
        {
                hash += (int)str[i]*i;
        }
        return hash;
}

That's kinda binary...really depends if the machine is on raw mode or something. Alright, that's pretty cool regardless. I was just curious.

I expanded my language to include addition and substraction. It's turning into pure spaghetti now though. If any of you wants to try to make something useful with it, go ahead.
https://github.com/salvadorp2001/64LMC

>>58267844

So... I'm looking through your specifications for this language, and I'm noting a few ambiguities here, particularly with regards to the output string. You start out saying it should be 9 bytes in size. You then say it is pulled from mailboxes x to x+7 when opcode 5 is used. This would mean 8 bytes are used for the string. Is the 9th byte always a null terminator? If we are taking one byte from each mailbox, since each mailbox is 8 bytes in size, are we taking the least significant byte (mod 256) each time? What should the behavior be if mailbox xxxx is valid, but mailbox xxxx+7 is not? Do mailbox numbers start at 0 or 1? You state that there is a maximum line limit of 64, and that some lines may be data, rather than instructions. Are we to assume that each line x is the initial value of mailbox x? If so, this implies a possibility of self modifying code, making interpreters and compilers both a bit more complex.

LAST POST OF 2016 FOR ME!

FUCK YOU 4CHAN

>>58268133
>This would mean 8 bytes are used for the string. Is the 9th byte always a null terminator?
That's what I meant, yes.

>are we taking the least significant byte each time?
I think that's what explicit casting

(char)mailbox

does, so that would be it.

>What should the behavior be if mailbox xxxx is valid, but mailbox xxxx+7 is not?
I actually hadn't thought about it. Do any languages not python have a behavior defined? I know C and C++ just Segfault my shit up.

>Do mailbox numbers start at 0 or 1?
Instructions meant for mailbox start at 1, but internally it's still a 0-index array so I just substracted 1 from the data number.

>are we to assume that each line x is the initial value of mailbox x?
Yes, that's the idea. Kind of like the Little Man Computer only this one is 5 digits instead of 3.

>If so, this implies a possibility of self modifying code, making interpreters and compilers both a bit more complex
That's why my interpreter is literally just an array of long long ints and my transpilers just output the interpreter with the code embedded. I have no idea how to go about this. It should be illegal for me to go near enterprise code seeing how I do this stuff.

It might not be a segmentation fault. You might just read from a random part of memory. In any case, I would do one of two things:

1. Throw an illegal instruction error if mailbox x > 57.
2. Zero pad the end of the string.

>Yes, that's the idea. Kind of like the Little Man Computer only this one is 5 digits instead of 3.
I have not actually heard of the "Little Man Computer", but I can see this would make compilation -- even JIT compilation -- incredibly difficult, as you would need to include code to recompile mailbox data regularly.

>>58268169

Happy New Year, Anon. How's things?

>>58268219
>Throw an illegal instruction error if mailbox x > 57.
This might actually work since no one is gonna be stupid enough to put their strings at the end of the program

>I have not actually heard of the "Little Man Computer"
It's a hypothetical architecture used to explain computing to students. It's like a mail office with little mailboxes that tell the postman what to do. It's pretty much the same as mine but with 3 digits instead of 5, and 99 boxes instead of 64. It also has the issue of self modification but I don't think anyone's been autistic enough to actually try to make a compiler for it, much less a JIT compiler.

>>58268239

>I don't think anyone's been autistic enough to actually try to make a compiler for it, much less a JIT compiler

Well, static compilation of self-modifying code is along the realm of impossible, so any compiler for this would have to be JIT. I'm not sure if a JIT compiler COULD get any performance boosts over straight interpretation, given the need to recompile every time a mailbox is changed.

>>58268225
My son turned 3 a few days ago and I'm getting healthier. Good so far.

Did you make your mind up on that research or work dilemmeam?

>>58268285
>I'm not sure if a JIT compiler COULD get any performance boosts over straight interpretation, given the need to recompile every time a mailbox is changed.
We're talking about a single-threaded proto-CPU architecture that can't even divide or multiply, I don't think a performance boost would even be noticed by most timers.

>>58268331

I am definitely doing research. Applied for a PhD at UW a couple of weeks ago, and currently working on an application for WSU.

>>58268335

Yeah, but if you could at least get it to use less instructions overall, it would be nice...

But now that I think about it, a JIT would involve regularly trashing the instruction cache, forcing the CPU to constantly go to RAM to get the new instructions, then decode them from scratch, effectively doing nothing while an equivalent interpreter would chug along slow and steady. The only times JIT can actually go fast is when you compile once, and then call the same section of code over and over again until the time spent compiling is drowned out by the performance gains of not re-interpreting the opcodes.

>>58268372
So would a JIT be useful in any kind of self-modifying-able language or are those forever condemned to interpreters?

By the way, LMC2C now outputs only C. I had to mangle the last fprintf because C is apparently a lot more autistic about newlines, but at least it works. I guess this also means I ported at least part of the interpreter to C.

>>58268426

Many languages that can self-modify are JIT-compiled, and run pretty fast. If you do a lot of eval() though, expect your performance to tank.

Are there any tools to get rid of indirect includes in C++?

I just ported the interpreter to standard C. It's half the size, and in the process I found out that C is anal about a lot of things.

mutexes are fine for basic locking, you don't need some silly wrapper just for that, it's when you start getting into more complex algorithms that you may want a pre-baked solution

Functional thread

>>58268853

>>58268686

The alternative to mutexes is not another locking mechanism, but rather, an architectural change that does not use locks at all. Use mutexes where necessary, but avoid sharing memory wherever possible in the first place.

>Then have your program talk to rtorrent, and bob's your uncle.
That's what it's actually going to do, although I'm doing it in a hacky way through rutorrent, because my torrent client is not on my main computer.

Happy new year anons!

So I've decided to learn and use rust this year. Just focusing on one language and after the year seeing if it's worth continuing. My plan is at least 1 hour a day, but I'm guessing it's going to be way less than that.

Happy new year friendos

hey guys I made you guys a stupid little cheat sheet for C pointers using a little set of loops that'll let you set a 3d object at the column, line and 2d levels and essentially make a 3d. I'm thinking if I keep going I could add the ability to port in types and snap it to a stream or something and read in input and ignore delimiters or something and then maybe thread it to read memory that isn't locked...

anyway here it is. It's really nothing but I don't know what to make. And I haven't been playing super nintendo.

http://pastebin.com/vFN5eUnd

I used the different kinds of pointers in different places to kind of give the idea of a structure being accessed by a vertex point, so not at the standard pointer or the limit but rather maybe the ansi screen drawing standard? Hanging sheets on little lines and passing them along.

>>58269432
Actually I think types is already in there since pointers are just pointers to ints... I think. Still, the whole thing could just be thrown in a function, type names changed to T and then signed a template and you'd have a nice little skeleton for a shoddy state machine, some short environment processor ( with room to transpose ) and maybe a bunch of other things I'm not going to do.

also just managed to install haskell

let the memes begin

>>58269432
oh and if I could explain

the pointer template at the top describes the extraction process from the top to the bottom so that you pick a function and plan out which other functions are going to be called so that you can stack them and then slowly work you're way down the lines to access the descendingly less dynamic variables. This way you can plan speedily without even trying. If you make every even iteration a draw to screen you could run a game off this with a few more constraints in some of the empty for loop parameters.

>>58269548
this, of course, assumes basic knowledge of the foundations of the language such as common keywords and things like pointer types. Still, it's good pointer practice.

How do I declare a fixed-length array of pointers to structs in C?

I feel like this shouldn't be hard but I'm drunk.

>>58270676

struct mystruct *stcon[LENGTH]

>>58270700
ok that's what I had written. Good.

Assuming the structs themselves are stored in a different array, operating on this array of pointers would modify those original structs in place, right?

I'm trying to share state between threads.

>>58270723
If you want to modify the actual structs themselves you should just have to dereference one of the elements.
The syntax to do that with structures I believe is.

stcon[0]->elem

>>58270723

Can anyone here tell me what sort of wizardry must I do to compile an opengl program (with glut and glew) on windows? Doing it on linux is already annoying, but at least doable. Trying to do it on windows, however, is making me reconsider whether or not to end 2017 early.

>>58273794

All I can say is, good luck, you'll need it.

>>58273861
Can any of you give me any sort of help? How did the windows guys do it?

I will prostitute myself on camera, via skype, for whichever one can help me. I can't offer anything but my body, but I'll make it worthwhile.

>>58273887
Are you compiling with VS or with mingw?

>>58273925
mingw, but I'll install VS if that's what it takes to be able to stop fiddling with window's incomprehensibly shitty ecosystem

>>58273958
They used VS so I'm not sure how much help I can be. I remember that they ended up just copy-and-pasting the dlls and the header files into their project directory to make it easier for the linker to find them.

What kind of compile errors are you getting?

>>58273794
What's the problem? All you have to do is download these libraries and shove them into lib/ and include/ (you could also keep them separate and provide the paths to the compiler instead but that's extra effort).

>>58274007
My problem is that I can't even link the libraries properly. I'm using codeblocks (I know), it says it has a glut dll somewhere, but it refuses to link it. I don't know exactly what options it's passing to mingw, but I'd expect it to work.

I don't know anymore, I don't know anything, I hate windows. I'm going to install VS and see if it makes any more sense than this piece of trash.

Question:

If i have a sql database and i want clients to access the data in it (just read it, not write anything in it), are there some best practices how to do it, do they access the data directly or are there some methods that they just receive reports/views/etc of actual data?

>>58274058
>I'm going to install VS and see if it makes any more sense than this piece of trash.
Building projects with VS won't be any easier. Post your Makefile, or however you specify build options on Code Blocks (I don't use it so I don't know how it works).

>>58274115
You can either build a simple API that retrieves the data frmo the database and outputs it to the clients in a specific format or you can make a new user with RO privileges and hand them the credentials but I don't think the latter is any good practice.

File: icosahedral_mesh.png (359KB, 800x600px) Image search: [Google]

359KB, 800x600px

First time posting in /dpt/!

I'm working on an icosahedral mesh generator. Icosahedral meshes are used extensively in Earth science simulations. Most of the codes that generate icosahedral meshes have some serious drawbacks, so I'm working on one that won't have those drawbacks.

For instance, in most (FORTRAN) codes, points on an icosahedral mesh will be generated by subdividing a face of an icosahedron and then projecting these points onto the surface of the unit sphere. This causes arcs between the vertices of the icosahedron to be subdivided into arcs of different lengths. My code uses spherical linear interpolation with quaternions to avoid this, resulting in triangular faces that are closer equilateral (which is better for solving numerical PDEs on the surface of the sphere). Most codes divide the surface of the sphere into 20*4^n or 20*9*4^(n-1) faces, but mine divides the sphere into 20*n^2 faces, enabling finer-grained control over the number of faces, which is useful if you want more resolution but don't have 4* the computational resources. In addition, all the codes that I've seen published are for use in graphics, and don't knit together the edges of the subdivided triangular faces. They're totally useless for numerical simulation without that feature.

Pic related shows that I'm able to generate the vertex coordinates, but I haven't written the code to generate the adjacency matrix yet.

If you have any questions, I'd be happy to answer them. Happy new year!

>>58274138

Might be a dumb question but how do I C++ in Linux?

>>58274205
Keep up the great work!

>>58274229
If you want to use an IDE you can try QtCreator (it's quite good outside of the Qt ecosystem). Otherwise yes, that's it, you get a text editor, and the compiler and perhaps a makefile or even use CMake.

>>58274229
Not a dumb question.

You need two things: g++ and a makefile (though you don't always need the makefile).

g++ is the compiler and the makefile essentially organizes the various compiler options. You can find instructions for both GNU make and g++ by typing 'make --help' and 'g++ help' into the terminal. If you don't have g++, on ubuntu, type 'sudo apt-get install g++' into the terminal. Have fun.

>>58274229
If you want you can use an IDE like CLion to provide something like your Windows experience. Personally though, I would recommend using a simple text editor, ideally integrated with your terminal like vim or emacs. Linux comes with a suite of command line utilities that you should become familiar with.

that's nice in theory, but it'd most likely make things harder on the eyes because choosing which thread to display is done by *moving the mouse over it* (not clicking). your method would require looking at the grid to the left so you could mouse to a thread and THEN looking to the right to see that thread. it'd be visually exhausting. if you've used browser, you'd understand the simplicity of having the thread preview follow the mouse.

Ah I figured you had it pop up in a random position within the main window frame on clicking the thread. You could do it sort of like gimp, have the threads pop up as different windows of their own as a panel; then you'd also be able to pop up multiple threads and leave the catalog centralized.

>>58274457
oh, and plus, having a dedicated area on the side for the thread preview would reduce real estate for the grid, which means less tile/threads could be displayed. the main goal is to be able to view the entire board all at once, without things being too small, and without the need to scroll.

In C, what happens if I have a pointer to an element of a dynamic array and then expand that array via realloc? Does the pointer stay valid?

e.g.

    int *foo = malloc(foo_size * sizeof *foo);
    /* ... */
    int *bar = &foo[3];
    /* ... */
    foo = realloc(foo, 2 * foo_size * sizeof *foo);
    /* does bar still point to the fourth element of foo? */

I assumed the pointer wouldn't stay valid but it did for some simple test cases I've tried. Still I suspect that's not guaranteed and was just a result of relatively little memory being shuffled about.

No it won't be valid if realloc gives a different address.

>>58275325
Definitely looks better

I'm writing a music player that will stream from youtube, bandcamp and so on. Basically mps-youtube but for normies; I want it to look like a normie music player like spotify or deezer. What would you like to see in such software?

Right now, every new feature added that should take a single day to do takes weeks. Like one we're working on right now- all it is is changing a boolean value for a specific U.S. state, and we need it by mid-Febuary, but everyone agrees that we will not hit that target date because of the fucked-up code.

Every deployment becomes a wild goose hunt of bugs and who coded what and buck-passing like crazy, as well.

If we clean up the code and not check in shit code in general, then we get more done, management will like the faster turn-around, and we all get paid more.

Lowering my goddamn blood pressure.

That's not really true

>>58275352
nice

>>58275343
Thanks, that's what I suspected.

I was planning to use such an array as a resizable (expandable) pool of objects which I'm assuming must be relatively common. What's the typical way to address this sort of problem?

Should I simply start keeping the index of the object in the pool instead of a pointer to it? That won't change on reallocation though it might make my code more complex since I'll have to do foo_pool[bar_index] instead of simply dereferencing *bar.

>>58275321
You can't.
pajeets are spawned on this earth as a reminder for (You) to practice good coding habits.

>>58275352
What framework are you using for the UI?

>>58275352
normalfags would probably like to see a download feature, maybe even entire albums

>>58275496
>management will like the faster turn-around, and we all get paid more.

As someone who has worked in companies who hired Pajeets, this is a laughable assertion.

>>58275321
You can't fix the Pajeet.

It's electron (basically a basic standalone version of chromium).
I thought it'd be easier to create a meme modern looking interface using all the css and js tricks and it's really easy to write a backend in basically anything you want.

>>58275531
Yep, I want to eventually download track lists and albums from some database and offer a function that will find links automatically. The difference will be that Deezer and Spotify only offer encrypted data and I will be able to give users mp3s or whatever.

>>58275507
*bar is not inherently less complex than foo_pool[bar_index]

>>58275507
The index could work, or if you want to just have pointers you could make like a pool struct that could be a linked list of memory chunks. So when you run out of memory in your pool instead of doing a realloc you just malloc a new one.

>>58275502
right
correction: everything thats useful is already implemented

Just make it simpler and flashier than Spotify and you're good.

>>58275590
Maybe but I'd much rather use the former.

Or

bar->child_bar

rather than

foo_pool[foo_pool[bar_index].child_bar_index]

>>58275619

Yes.

83 unique IDs seems like a lot.

Are there a bunch of "new years resolution is to code"fags here?

I can't believe how good ActivePresenter is, considering it's free. there must be a catch.

how can't it?
even if it can, how are supposed to know?
no c programmer should have to know shit and they don't, by design.
