Depends which industry we're talking about. There's a demand for both C++ and Java programmers. But they're both easy enough to learn that you don't need to pick one over the other.

If you have 2 activities equally (for example programming and drawing), and you want to do it professionally both, which one would you choose?

>>58480822
Programming, and drawing after work.

>>58480822
Well professionally I would want a job that didn't involve drawing furry art for autists for a living, so programming. Then drawing as a hobby. Also, don't you think this is an incredibly biased place to ask such a question?

Can make the SSD write directly into GPU memory (RDMA), instead of having to transfer first to RAM and then to the GPU.

You have a misunderstading of modern drawing, take a look at ArtStation, there are a lot of artists who draw concept art for games and films.

Tension is rising

>>58481009
It will be faster and require less synchronization between disk driver, OS and GPU driver.

>>58481111
Quicker for what function? I can only imagine this would be quicker if the data set was significantly larger than the available RAM. If the data set could be cached in RAM then doing a transfer from SSD to GPU would be slower and therefore redundant. Unless you were crunching very large sets of data, this wouldn't be much faster.

>>58481111
Is is actually practical though? Bypassing the OpenGL driver sounds like begging for trouble.

>>58481284
If you want an actual suggestion, when I was in uni, we coded a fabric simulation over a sphere. You don't have to code a full physics sim, just push the fabric outside a given radius every tick.

The fabric is basically an array of points. Apply gravity to points, use hooks law to simulate a spring between adjacent points, repeat ad infinitum.

I made every square a different color and it looked like a million bucks. If you've had experience coding, it'll take you a couple of afternoon.

What is your stance on parenthesis in mathematical operations? Would you write

y = a + b * c;

y = a + (b * c);

>>58481336
depends. More often than not, I'll do the latter. I find the first one readable enough, but when things get more complicated it makes more sense just to add parenthesis everywhere to make it easier to follow. So even for simple ones I just add the parenthesis to keep everything consistent.

>Knee socks are for people who get down on their knees too often.
But what if it was a game theory scenario? Two people are in seperate and isolated booths, unable to see each other but able to communicate through a walkie talkie system. If they both leave the booth without wearing the knee socks, then they're both pronounced "totally not gay", but if one of them wears the socks, then they're both pronounced "gay as fuck". Then they have to communicate and do all that shit.

>>58481336
Second one, every time. I have a paranoia about it, even with calculators. I feel that if I don't explicitly state it then it'll be interpreted wrong because of some Chinese fuck who doesn't understand order of operations.

Very briefly, it's very often symptomatic of other issues. To lean on goto, is to forgo best practices For example in your code, it would be much clearer to write

while( i >= c[j] ) {
            i -= c[j];
            k++;    
}

rather then using your goto statement.

Where do people even learn to use goto statements? Who teaches that? Did they pick up a book that's over 40 years old?

90 may not exist, since there are other commands which let to get out from the loop.
Still, GOTO may be useful to jump out multi-nested loops. GOTO is like a knife - you tell little kids that it's forbidden to use knife until they get older, so they wouldn't cut their fingers.

>postfix ++

Goto is not evil in and of itself. There are, however, many reasonable alternatives to goto, such as break, continue, returning early from a function, and regular old looping constructs, depending upon the case. Among the few legitimate uses where a goto makes sense are breaking out of a nested loop early, and jumping to a cleanup section in a function. One case I found myself wishing I had goto was in an operating systems class, where I was allocating multiple resources, which could fail in allocation, requiring the release of all already held resources. The language I was using had no RAII or goto, so if had multiple conditionals where I would release all held resources by the function. It was a bit ugly. With a goto, I could release all resources at the end of the function in reverse order of allocation, and put a label in front of each one.

>>58481856
Well yeah, that's the only place where it still makes any sense. But who learns that first when it's fallen out of common usage? You'd have to want to start programming, decide to learn assembly for some reason, then go to C.

Programmers don't like using jump commands because they don't like being reminded of physical exercise.

Reading through the classic Gang of Four Design Patterns book now. I've known of it for years and some of the larger patterns, but how relevant is it still today? I always assumed it was deprecated, so I put off reading it for years until now.

Also how good is the Scott Meyers Effective C++ (the C++11 and C++14 edition)? I read the old 90s edition, but kind of gave up on keeping up with C++ after awhile because it got too expansive and complicated for little reward.

Also am I a complete dumb ass for reading the classics like Clean Code, The Pragmatic Programmer, The Practice of Programming, etc while my peers seem to be reading the latest meme Javascript packages? I honestly enjoy reading Math and algorithms books over most of this stuff, so I try to only read the essentials and stick to math textbooks.

I'm trying to work with multi-dimensional arrays in C but I'm having an issue, I need an array of pointers to arrays, the arrays that are pointed to are just arrays of ints, but the size of them isn't the same, I'll know the sizes at compile time but I can't define them in the type itself. On top of that I need pointers to those arrays of pointers too. This is causing me issues.

Essentially I want to be able to do this.

typedef int layer3[]; //array of ints
typedef layer3 **layer2; //array of pointers to arrays of ints
typedef layer2 **layer1; //array of pointers to arrays of pointers to ints

layer1 layerSet1 = (layer1[1][1][2]){ //layer1, set 1
        { //layer2, set 1
                        {20,6}, //layer3 set 1
                        {20,7}, //set 2...
                        {20,8},
                        {20,9},
                        {20,10}
        }
    };

It doesn't matter how it's defined, I just need to be able to define the structures easily in literals, and they have to be 3 dimensional like that. The

(layer1[1][1][2])

is not valid but I want to be able to do something like that, have the array size unknown at the typedef but defined later in a literal, still at compile time (I won't do anything at run time).

Is something like this possible? I'm not super familiar with C's syntax surrounding multi-dimensional arrays, nor am I familiar with macros. Is there syntax for what I need or could/should I learn macros to deal with this?

>>58481996
What about the wizard book?

>>58482009

This is a nice meme, but can you pontificate on it? I know in the industry they typical talk in terms of patterns, not necessarily strictly referring to the original definition, but still in the same abstract idea.

You sure you're not overthinking this mate? That's a lot of pointers pointing to pointers pointing to ints, is it really necessary?

>>58482042
People make fun of design patterns for being overused and over depended upon. But they are somewhat eye opening, and it helps to have a bunch of standard approaches to problems in your head when discussing how to solve certain problems with your work peers.

>>58482068
Design patterns are fucking dumb and symptomatic of bad programming practice.

90% of them exist to work out "how to do X with inheritance"
maybe stop using inheritance, you stupid OOP idiots

>>58482129
>a dog is not an animal.
you deserve an award

>>58482061
I'm not really sure, but I'm pretty sure. Basically I need to iterate over those ints 1 at a time, between those I need to iterate over another set of them, not back to back but interleaved.

Kind of like this
layer1[0][0][1]
layer1[0][1][1]
layer1[1][1][1]
layer1[0][0][2]
layer1[0][1][2]
layer1[1][1][2]
etc.
I'm using pointers because the actual data will be larger and I need to switch between them very quickly. At any point I need to be able to stop, not after a whole set but only after a single point, so it has to be broken up into 3 dimensions as far as I can tell.

It's for video, layer 3 is a set of frame data, layer2 is a set of frames, and layer1 is a collection of animations, I have to play a frame from 1 animation, then play the frame from another animation, interleaving them, so I have to keep track of which frame from which animation the "cursors" are on.

I might be over complicating the solution but the requirements are already complicated. It's be much easier if it didn't have to be interruptible, it'd be even easier if they didn't have to be interleaved.

>>58482129
Design patterns are good, but don't implement them literally.

I wrote something to deal with a 3D array like that, I just don't know how to initialize that array with semi-dynamic sizes, if I used fixed length arrays the tests are working fine, it's just defining that data that's giving me problems. I need a type inbetween fixed length and variable length, the data isn't dynamic but it's not all the same either.

There seems to be a lot of alternatives I could take but none of them preserve the literal notation, other approaches would push the memory onto the heap too, which I'm not opposed to here but it calls for me to handle sending some literal to a function for each set of data instead of just defining them all literally and referencing them all in layer1. There might not be a way to do this simply.

I'm not gonna try to post the code because I'm only looking for broad answers

it's trying to draw 1 sphere with a radius of .5 that is 1 unit away from the camera by painting it red if the ray is a hit and black if it is not

I tried two common methods of ray-sphere collision detection. Both of them give me this same result.

As the sphere moves away from the frame, the wedges get smaller as if the wedge width is inversely proportional to distance squared

>>58483184
What do I care about some 3rd world country like Kwanzania?

>>58483144
Immigrants (with the exception of between countries that have freedom of movement, like EU member states) do not have the same intelligence distribution as the population as a whole of their country of origin: more intelligent people are more likely to emigrate than less intelligent people (it's much harder to immigrate to a first world country if you don't have a degree, or skills, or a offer for a job in a sector with a skills shortage, etc.), so immigrant kids are likely to come from smart parents, and intelligence has some degree of heritability.

So Indian immigrants probably have a higher mean IQ than the native population of their destination country, but you can't extrapolate from that to say that Indians are more intelligent than them. If India wasn't a shithole you'd see the same in the opposite direction: the smartest whites moving there, and their kids scoring higher than natives' kids.

>>58483230
>, but you can't extrapolate from that to say that Indians are more intelligent than them.
but IQ tests run in india also show they are more intelligent than westerners. Where's the evidence that they aren't?

>>58483230

Brahmins are likely more intelligent, but those are a very small group.

>No they don't, generally.

>>58483308
I simply don;t assume the IQ tests definitely are cheated on in order to back up a narrative.

>>58483334
No, you simply ignore all the evidence that cheating occurs in order to back up your own narrative.

>>58483006
its not about replacement it's about protecting the jobs while we have them. indians abuse the h1b system of the US to send in shitty programmers to depress wages and take up lottery positions that should be filled by other more important professions.
It's a shitty system that takes advantage of shitty, desperate people. That's why i hate them.

if you're outside the US, it's probably not an issue.

>>58483363
Don't forget there's also the diversity lottery visas, which serve no purpose other than to make the US more 'diverse'.

>>58483352
I don't ignore it, but evidence of cheating is not proof that indian IQ's are not on average higher than western ones. It simply means we don't know.

>>58483407
Look, I will consider that your test is evidence of higher IQ and that higher IQ is evidence of higher intelligence when the average indian can do the following things:

- not wipe his ass with his hand after shitting
- not bathe in a sewer river
- not shit in the streets
- not spit on the sidewalk every 5 seconds
- start taking regular showers to remove the curry smell
- have running water

Until then, I will treat your tests the same way I treat crystal healing, astral travel, and professional wrestling.

How do you set global variables in OpenCL?

In my regular code, I have Char[ x , y ] (2D) which denotes the game map, each element/char denotes a tile. Afaik I cant give the GPU a 2d array, so i have to convert it to 1d. This isn't a problem since you can access it like array[width * row + col] = value. But I need to set Width as a constant/global variable for all the threads in the gpu for easy indexing.

Does anyone know how to set it?

An alternative would be to give it to the gpu and to pass the width on to each method but that's ugly code imo.

i want something like this:

__constant int _MapWidth;
__constant char _GameMap[];


__kernel void device_function(__global char* GameMap, int width... )
{

_MapWidth = width; //set global Width
_GameMap = GameMap; //set the given map as read only (this wont be manipulated)

}

Design patterns are a language. If two programmers know the same design patterns and both use them, it will be easier for each of them to understand the other's code.

On the other hand, design patterns are duplication. If the language was more powerful, the structures they describe would be abstracted away and reused. On top of that, most OOP design patterns are either plain harmful or irrelevant now that even the big OOP languages are integrating functional stuff.
