The BSD and MIT licenses because they do not violate elementary property rights to the sole benefit of a small subset of programmers
>all your source are belong to us
But if you meant free as in marxist bullshit about being free from ever having to rely on others and even exchange capital for goods and services, the GPL because it robs developers of their private data so you can keep a small portion of your self determination.
BSD = free software
GPL = communal/communist software or "software of the people"

No need for a spoon to dissolve such a vapid and feeble reasonning.
Quick question.
If I want to relicense my code to another license and I've accepted a few pull requests on github, would I legally have to rewrite their contributions in order to say the software is completely mine to relicense again?
>>54037475

I write software to contribute to free software.
The GPL license says only 1 thing: You're free to reuse my code so long as you give other users the same liberties I gave you.
I gave them the right to look and freely adapt my source code, they should be obligated to do the same.
If you are not willing to abide by the terms of my license, you're free to use someone else's code.
>>54037475
>TAKE all your software
You shared a copy of the source. They didn't take anything.

My compiler is screaming at me to fix the below code, but I'm not sure what's wrong with it. For the record I'm sure it isn't the logic in the function body, I'm doing something wrong in the declaration but I don't know what:
template<class T, int, bool>
bool validate(const T obja, const T objb, const T[], int num, bool v = true) {
bool result = true;
for (int i = 0; i < num; i++) {
if (arr[i] <= obja || arr[i] >= objb) {
v[i] = 0;
result = 0;
}
}
return result;
}
>>54037750
>bool v
>v[i]
>>54037750
I'm not 100% on how C++ templates work, but do you have to name your 'const T[]'?
>>54037763
It's a boolean array. Forgot to add the [].
>>54037750
>'arr': undeclared identifier
>subscript requires array or pointer type
> I'm not sure what's wrong with it
Are you compiling in your head or something?
>>54037800
It's an array of type T. Dunno why but it only works that way, it won't accept an identifier.
>>54037657
>IP law leveraged for communist purposes still strips people of the right to their own data, which is not data they made, but data they possess on their own storage medium
If your ideal world is one without copyright constrains, then a GPL'd communal domain is what's closer to it IRL. Copyleft is using copyright law in order to forbid you from using it against others, whereas MIT licensed software can be twisted in order to create a situation where someone possesses data but doesn't own it. It's obviously limitedly effective but it's the best we've got. Also: do you consider compiled software an acceptable form of owned data? I think the requirement to distribute source code along with software is right, don't you? why?
>>54037832
Made recent changes and forgot to change the variable names inside. Still p. sure that itsn't the problem, just wanted feedback on the actual declaration

You have been visited by the 3 star programmer of Shimoshina Academy!
Good performance, triple indirection, and tail call optimization will come to you, but only if you post "Keep overflowing the stack, Hime!".
>>54037750
You want to name the second template parameter and the third template parameter. I am not sure if const T[] will ever work. Usually you pass a pointer to T and arraySize.. You also want to pass references instead of making copies for performance reasons in this case (other case is when you want to locally modify the passed parameter but you don't do that here..).
I suggest:template<class T, int NAME_OF_INT, bool NAME_OF_BOOL>
bool validate(const T& obja, const T& objb, const T* arrayPtr, int arraySize, int num, bool v = true) {
//I don't care about the code only the declaration :)
}
>>54038144
I'd overflow that stack.
If you know what I mean.
>>54038005
C++. Java will teach you bad practices and enforce bad practices while C++ lets you do either bad practies or good practies.
You will learn more and be surrounded by more competent programmers if you go with C++ (I believe).

Yes.
Although I don't know if this is just confirmation bias on my part. My experience with Java programmers are they just recite shit from memory without actually thinking about the code they write. Probably because Java is fucked syntactically.

>>54038427
>>54038443
botnet please go what are you trying to hide
>>54038362
Not really sure what you're asking. In OpenGL when you upload a texture you usually apply it onto geometry. You do this in the shader with a sampler object.
You can play with the texture coordinate values to manipulate the aspect ratio.
Interpolation happens automatically by OpenGL. You can set the texture property to either Linear or Nearest (might have additional modes in GL3.3 idunno) for different kinds of interpolation

ok, so let me explain why you should never do that and how to do it.
1) YOU ARE GIVING A WEBSERVER ROOT ACCESS.. Rule 1 is NEVER EVER EVER trust users..
2) If somehow it gets exploited you just gave them root on your box and pretty much ever other PC which that box can access.
The proper way is to use something like redis or etcd and store work items in there then have a daemon processing the items. Have the daemon on a white list system so it will not run unknown commands.

This is my biggest problem with trying to get a job. I just don't have the ability to do the kinds of problems they ask in interviews and on interview sites like codility or hackerrank.
I've written tons of things in C, C++, JS, both small tools and full applications. I've done graphics programming with OpenGL, audio programming with GStreamer, interfaced with embedded, serial port programming etc and no one gives a shit at all because I just fucking suck at the programming puzzles
Its really frustrating and depressing. I've read cracking the coding interview, I try to do 'puzzle problems' every so often but I just don't have that kind of thinking ability.
It feels so unfair man. Like no matter how hard I work or how many practical things I can do I'm just fucked because my brain can't think in that way. I wish they would have screened for this sort of shit during my degree and failed me so I could have just moved on to some other field.

I never implied anyone owes me a job. All I said was that I wish I had a better idea that you had to be good at this sort of thing to get a job in the industry, and specifically that my university made it clear.
Usually you go to school to get the skills and knowledge you need to succeed in a career. But it feels like my degree is useless because I can't solve the kinds of problems that most interviewers look for.
No idea why you're so angry
>>54039741
I don't really have anything off the top of my head. Usually it starts out okay, they give you a problem and its straightforward for me to solve it in a naive way. Then pretty much all of the problems have a 'trick' where you have to go through like an 'aha!' moment to figure out a performant non-naive solution that has better complexity.

why are you writing so much boilerplate just so you can use snake case for your json files

Have you tried playing around with texture at all yet? If you want bicubic interpolation I think you can just set texture filtering to GL_NEAREST.
Then you can manually sample the texture in the fragment shader and apply whatever filtering you want (I don't know how bicubic works, but basically once you're in the fragment shader you can use texcoords to look up whatever pixel you want in the texture and interpolate them however you see fit)

I feel for you. As an outsider to the field who got incredibly lucky to get a job, I feel for you. I suppose there are two things you can do, they are not exclusive:
1. Put something good on github and point to it. They might make you take the test anyway, so lower their expectations.
2. Yes, often there is the aha-moment. You may run into some problem you have never seen before. But there are like <20 concepts that come up consistently. Memorize them and check if one of them applies. If the test is in person, explain the naive algorithm - that will buy you time and demonstrate understanding.

like could I call that function and use the pointer is returns as a new string?
I want to write something like image converter. It opens a 256 color dos palette image and outputs info about each pixel that can be used in dos mode.
So later on I could simply open that output file, write it into dos video memory and have that image on screen.
In what data structure would I store that color info? In some kind of map? ARGB value of pixel would be the key, and dos byte value would be the value.
What are some good free and opensource polymorphic engines?

std::stack is an array like the calloc definition except it's dynamic
Well I finally fucking figured out why int13h;ah=48h wasn't working, I didn't set the buffer size, I assumed it was filled in by the BIOS, not the programmer.
That also explains why removing the drive_no byte caused the function to work.
>>54040961
They are similar, except std::stack limits functionality like insert etc. so it can be made sure the container acts like a stack and guarantees it

>>54041196
>>54041232
its not an array, arrays are implemented with pointers. pointers are not arrays. ** is just a pointer to a pointer
>>54041196
You're in a room, and you want your mate to pick up an object for you, your mate doesn't know where the object is, so you point to the object using your finger to show him where it is, he then picks it up for you and gives it to you.
But of course, you could just not be a lazy fuck and go get the object yourself, but other lazy fucks would call you out on "reinventing the wheel" if you did that.
>>54041239
yeah I got that, but why do you need them?
>>54041232
It's a pointer to a pointer. A location in memory which holds a location in memory which holds your 'Node'.

This. The CS department wants me (ECE undergrad) to help a student with a capstone project related to IoT because no one in the department knows shit about embedded programming.

Basically a group of students pick a project to work on during their last semester (or last two if you're engineering at my school), then they design, implement, and write a paper on the project. Training for a thesis or dissertation I guess. At my school they tend to be more adventurous and lengthy than the grad school projects, but slightly less technical, because there are multiple people working on them. Most schools I've seen have them in STEM majors.
I'm working on autonomous navigation systems this year and helped with a project last year on the controls and data logging systems of an experiment that was put up in space by NASA.

I worked in an agile/scrum environment. I've done both daily and weekly scrums and at least where I've been the take away from both was that it's super easy to work at your own pace as long as you're meeting deadlines. In my case I was also the one making the estimates for those deadlines. I was able to set myself 'standard' deadlines and generally finish the work far far faster after which I could slack off at work and say I'm done whenever, if it got too boring all you need to do is move onto your next task. Other people I worked with had that real perfectionist mentality as well, so long as you're still getting your shit done it shouldn't be a problem. All of that dynamic team bullshit is just buzzwords, if you get along with your colleagues you have nothing to worry about.
All of this is subjective to the 1 month internship and 1 year contract I've worked so your experience may be different but there's really not much you need to worry about. You can probably score some easy points at an interview if you read up about scrums and scrum masters and can spout off some of the buzzwords in good context.

Javascript will give you the most employability points. Its not going anywhere any time soon and its in demand everywhere.

I'd say you learn JavaScript first and then when you get sick of it (and you will), check out C and C++ so you appreciate what strongly typed languages are all about.
