I'm working in Java. I have this generic tree that I do some action on. The method requires me to return a generic polymorphic binary search tree. I can't cast to the polymorphic binary search tree because there is no inheritance relationship. I'm stuck.

My niece wants to learn C. She's 14 years old.
I've learnt C a long time ago from various resources not worth mentioning now (not K&R).
What would /g/ recommend her? What is The Book to learn C from nowadays? Still K&R, or maybe something more modern?

I don't remember the title, but the "learn how to program C with your beloved anime characters" book

>>57561062
Teach her C++ first, then teach her C.

In my experience as an instructor, its actually easier to teach C++ students C, than C students C++.

And if she learns C, she's going to want to learn C++ anyway.

As for books, Absolute C++ is good. For C nothing beats the real K&R

>>57561062
K&R could be a bit to abstract and may take away the joy of programming. let her start with a magnetic needle.

that you do some action on? you wouldn't by any chance happen to be black, would you?

A tree is just an interface you use in traversing an array or list in a proper order. So essentially you dont so anything to the tree but invoke it, reconfigure traversal/sort or put it away. What exactly is keeping you from doing any of the above?
and just as an act of pre emtpion, you dont do sorting. sorting occurs in the matter of pulling or inserting the elements in particular indices. Each case abiding a separate entity. When you pull you designate the sorting algorith to pause and supply you the info you need. When you insert, you either pause the sort or add the element prior to sorting and let it sort itself out.

Now, what do you need again?

Google C and levels of indirection.

Im meaning that she can apply hierarchies from the level of pointers without having to cater her coding practice and style to the level of the monkey coder idiot. This will help with her maths, english, programming, c, history, chemical engineering, etc. As long as she can keep track of her own work, she'll have no problems and not to mention that the simple syntax will make the learning of other structures a breeze from then on.

If the C ecample sounds, silly, its just like the employee, factory and company analogy used in the books except you dont involve pajeet and his village idiot list of cronies. If that doesnt make sense to you, maybe it will for her. It'll also help keep her humble.

i think you mean 0 was on a need to know basis. each worker was given a different task, all under the same rule, and it wasnt necessary for everyone to understand or know what was going on with the whole thing. hence roles in civilization and a gendered outcry from the uneducated yet educated majority. the men didnt know what the women were thinking and the women didnt need to know what the men were doing. eventually this form of civilization broke down and the greater understanding became more relevant, but still under the pretense of privileged versus the need to know basis.

It's a matter of, "Do I want to go into research, or should I try my hand at programming in the industry?" My portfolio is fairly shit, but I might be able to score a job at Microsoft if I can play up to my skills well enough. On the flip side, my GRE scores were pretty decent, and it would be trivial for me to get the letters of recommendation to go into academia. With an academic job, I have a few more opportunities, both to work as a professor (and many universities are looking for new professors as students at jumping into computer science in large numbers), or to do private research (I could always work at Microsoft Research afterwards, which requires a PhD).

This would mean about 3 more years of stress through academia, but I suppose it might be better for job opportunities?

New to pointers. How do I point a variable to another, do shit to the first and have it reflect on the second?

y++;

>>57563877

y = &x;

#define pointer *

int x = 1;
int pointer y = at x;

That's what I thought it was but trying it now:

    int x = 0;
    int * y = &x;
    *++y;
    cout << x;

Output is 0.

>>57563948

*++y;

This increments the memory address y is holding before dereferencing it

>>57563948

Oh, this seemed to work.

    int x = 0;
    int *y = &x;
    *y += 1;
    cout << x;

Is it possible to use a loop inside a conditional in C?
Also, anyone have good resources to learn PHP?

>>57565739
>loop inside a conditional
WHY

>>57565747
Originally I wanted to do it for convoluted reasons that wouldn't solve my problem.
But that was a while ago, and I've already fixed it. Now I'm just curious.

>>57565628
>>57565680
Also, follow-up question: would batch normalization help with vanishing gradients, or is that for something else?

I'm just trying to find what methods there are for getting deeper networks without resorting to LSTM's.

>>57565747
So is that a no?

>>57565843
int n = b ? max : 0;
for (; n < max; ++n) ...;

>>57565784
Batch normalization wouldn't help with vanishing gradients. Do you understand what vanishing gradients are?

>>57565857
the for loop isn't part of b

>>57565889
>help mum i am retarded pls

>>57565883
Yes I do. It was my understanding that batch normalization granted you greater control over the backpropagation process so that you don't "spend" all of your gradient near the bottom of the network. That must have been mistaken, though.

anything that teaches PHP is a bad resource

C has become magical.

#include "multiply.h"
#include <string.h>
void multiply(int m, int k, int n,
          double (*res)[n],
          const double (*x1)[k],
          const double (*x2)[n])
{
  memset(res, 0, sizeof(double) * m * n);
  for (int i = 0; i < m; i++) 
    for (int l = 0; l < k; l++)
      for (int j = 0; j < n; j++)
    res[i][j] += x1[i][l] * x2[l][j];
}

so I got some neural implants. I need to write a program that could boost my calculation speed. for example an equation that now takes me 10 seconds to solve will take a lot lesser.
Which language should I use to write this calculation assistance?

>>57566275
I don't get it

>>57565942
That's quite a generalization. Batch normalization is used because it allows increasing learning rates. While it might positively affect changes near the top, the goal is faster training.

Calm your shit.
1: There will ALWAYS be programmers who are better than you.
2: If you're doing it right, you are pretty much always improving.
3: A common (and fair) complaint about textbook exercises is that they present you a perfect solution, when in reality, the solution almost was never written perfectly in one go. (There was this really good article written on this in the context of the 'Handmade Hero' youtube series but I can't find it). Generally what you'll do is you'll write something that approximates the problem, then test it and find out that it doesn't work for some edge case, then fix it up, and then maybe it works well but you now see a way you could have written it better, so then you do it that way, or maybe for some harder problems you do all of that for a subset of a problem.

Asking opinions. I currently know C# and python, and actively use them both. From a 100% employment opportunities standpoint, which languages should I learn next? I was thinking java and C. I already know C basics, as I learned it in school many years ago, so I suppose it will be easy to refresh. I just want to be well rounded enough to be seriously considered for the largest amount of positions. I know I'm asking a lot from a Malaysian recipe board but any help would be appreciated.

>A common (and fair) complaint about textbook exercises is that they present you a perfect solution, when in reality, the solution almost was never written perfectly in one go
It's the same with math. E.g. Greeks loved to pass on only their perfect, pampered, elegant proofs of theorems which were supposed to emphasize the beauty of logic, while omitting the dirty process in which they got their results. That's just how their religion and philosophy worked like.
But if you think e.g. the Pythagorean theorem was invented in a way its proof was presented, then you are just simply not aware of all of the work Egyptians put into it before Greeks. Same thing is said about Euclid proof of infinity of primes which is often presented as a marble of reasoning.
This trend survived through ages. And don't even make me started about all of the shit that went on with calculus. If you're studying math, and you have the option, take math history course. It's enlightening to learn about all the things and work that had to be done to discover certain things and the order in which those discoveries were made.

I stopped caring about Haskell when I was introduced to the concept of monads. What a crock of shit. If your program can only modify state by inventing a higher-order abstraction that can't exist, like some kind of programming deity, then you are fucking wrong and the language is flawed. Same for type checking that basically says "the correct type is whatever the correct type is". That's what the error message said transcribed to words, but god forbid if i wrote in down in English instead of the meme Haskell runes that GHC marks me wrong.

Haskell is logical and category theory never lies my ass. Haskell is just as flawed as any other """"functional"""" language.

I'm in the process of picking up JavaScript. It's my first real attempt at learning a programming language. I tried Python a while ago, but it doesn't quite "click" in my head as JS does.

I wasn't sure where to start, so I've spent this week going through all the free JS courses on codecademy.

Where would you recommend I move on to next? I really enjoyed the interactive learning aspects of codecademy, but now that I'm done I don't feel like I've learned any way to actually apply what I learned to solve tasks and problems in the real world.

I cant imagine id be working with anyone that would care to do more than code the same, boring old modality over and over. research would at least lemme test out new things frequently. i figure that research would give you "hands on" with some pretty gnarly interfaces too.

The problem is that they're trying to shoehorn women into programimg and other STEMish careers just to prove they can do anything men can do (you won't see a push for female plumbers or carpenters). I have no problem with women being programmers but putting this pressure on them to take on something they probably won't even like is concerning. Not only that,but men handle shit better than women. I've seen some senior level female programmers lose their fucking shit when they fuck up their code and can't fix it.

>>57567601
why dont you ask them what they want? that read like youre saying "they" are to prove themselves omnipoten from a distance rather than that women are bei.g shown to be capable. I think thats a big part of the push. women read it and get triggered and suddenly theres a push for the change as it was instigated.

its silly i know but i cant help but see it that way considering the way women are protesting amd considering how often youll see ot worded exactly as youve phrased it. its called a lazy algorithm.

>JS as first programming language

Oh shit, what are you doing?!

But if you really want to, read "Eloquent JavaScript" and DO THE EXCERCISES:
>http://eloquentjavascript.net

After that you could look into "JavaScript: the good parts", which is basically a list of JS do's and dont's..

And after than you can dabble into "ECMA Script 6", the new version of JS. Or learn something like Typescript, CoffeScript..
Btu don't get tempted to skip really get a good understanding of JS before getting into the newer stuff. It will pay off to get the basics first.

>>57567790

Oh, I just noticed you alredy did the codeacademy stuff..

Well, in "Eloquent JavaScript" are two smaller projects you could do.

Or learn ECMA6 and then build a website. Or learn Node.JS. Or start building plain old websites with HTML, CSS and JS. Or learn fancy JS libraries like D3.js...

Thanks. I realize it might not be the best starting point, but so far I'm really grasping the basics, and it's a lot of fun.

My plan is to not get into library usage like nodeJS or jQuery and instead learn as much as I can from doing plain JS. Once I'm comfortable, I'll get into nodeJS.

Thanks for the advice though. I'll check out the projects in "Eloquent Javascript" then move on to ECMA.

No problem, JS is fun. And being good in JS is definately a good plan for whatever you do later.

But be aware that most programming languages are pretty different from JS..

jQuery doesn'T bring anything new to the table, but it's making your life much easier. So yes, do that next (also build a website and apply all those jQuery stuff !).

Node.JS is a different beast, since you have to get what the internet really is: client/server architecture, TCP/IP vs. UDP, HTML status codes.. that's only the tip of the iceberg.

If you go into web development there's a lot of stuff you have to learn at the same time. But once you understood them, it gets easier, so don't get frustrated and tackle them one by one Just use wikipedia or ask here.

Group one are the ones that are interested in tech stuff and don't give a flying f about gender. Those are usually pretty good coworkers, fairly skilled and great to have in your team.

Trump won't make america great again. He believes in shit-tarded memes like "global warming isn't real" and "vaccines cause autism". He will inflame the left and make them even more idiotic possibly resulting in a leftist version of trump in 2020. Protectionism is a stupid economic policy. He is an aging senile boomer celebrity with no political experience who will be manipulated by shills and yes-men even if he genuinely believes in clearing out the swamp.

I say this as a conservative who dislikes the whole SJW thing. He could have deported illegal immigrants without all this other bullshit. I very much doubt he will make much progress even on this issue since he is so incompetent.

>>57567916
cause the leader isnt black anymore and so to "rome as the romans do" no longer means to mimic black people....as they mimic their mothers or asian stuff. The thing with that is the difference between phonic and lexical which really hurts my head to think about since ive always been lexical and only went the phonic route when trying to discuss things with people that dont speak regular english or deal with people that grew up around the crimunal element and have come to accept it as "normal". So, yeah, the issue is gone as far as what's american, again. I dont mind that women do that thing theybdo and nag and oull ears for attention but as long as they arent doing it the way black men and black women do it in okay with itbhappening and can ignore it...cause, really. whens the last time you were "allowed" to just ignore a black person? shit, when's the last time you were allowed to just ignore a group of people? I really cant remember anymore.

like, really, not even in a school in the middle of neo nazi central or in the middle of mew york using an atm in a majority black burb was i ever called a spic. i dont get the argument but im not a loud person anyway. i also dont discount the potential for their word to be weighed more strongly against mine.

more heavily*

might i add that ive always lived in a shit neighborhood and have been pulled down by friends or family as ive made any form of ascent. the thought that id ever have to account for a majority or minority just based on my skin color and possible heritage doesnt gel with me. i was raised christian, for christ's sake. "there is no salvation but through the graces of God".
I can see that mexicans are not doing right by what theyre being given, especially not now that they had all the opportunities in the world to truly come together and not just gather in protest for rights. instead they sold themselves to an ideal that would allow them a sense of hubris in place of the satisfaction of having done the job right, rather than simply having the right job. these new laws about immigration? they arent even unfair and only apply to criminal felons. the types of criminals that create a status quo within the limits of the culture as if it were our civic duty as folk that reflect light as poorly, as made evident by the tone of their skin, to keep each other from advancing and to force everyone to understand "you!" rather than to just let them go on by while you keep to your plans. we screw shit up for ourselves...but still... i can see, and have seen firsthand, the point of initiation. fobs. doesnt matter where from, they bring trouble on a scale tantamount to the collective intwlligence of the other "skins" and really from there its eitger you take them out or you learn to live among them as they live out their derangements.

anyway, enough about how easily liberal psychology and social engineering can plague the status quo if you let it run rampant and hidden in plain sight. i just wish they were more precise, less lazy and didnt just throw the book at it with equivocation to blame or derangement to flout. lets talk c.

>>57568272
anyone here got anything to add to the tables?

Try not to get sucked into the decades-old 'LISP for AI' concept that /dpt/ parrots. They're great languages which you should try, but they're not mandatory for AI.

You won't succeed without corporation-scale hardware. Note that all speech analysis services available on your phone send the audio to a farm to be processed.

In MySQL, when I make an update statement and it does match some rows, but does no changes to them, how do I get the number of rows matched?

Like if I have a row a=1, b=2, c=3, and I make an update statement to change b=2 where a=1, the update will match that row, but will not change it.

Why not use a similar SELECT statement prior to the UPDATE?

Because the where clause is slow, I don't want to do it twice.

>>57568724
If you have an index on the relevant column and do a

SELECT COUNT* FROM table WHERE a = 1

, it shouldn't be that slow.

>>57568945
>COUNT*

COUNT(*)

, that is

i'm not a count I'm a duke!

That abc example was a gross oversimplification, its a multi table query with pattern matching in the where statement, including others. I want to avoid doing a select, because it would be slow.
I am doing this with PHP, by the way, but mysqli_info's rows matched seems unreliable, it doesn't always return the correct value.

It's one of the remains of unix ideology - each tool should do one task well.

It has some pedagogical porpuses, since it doesn't babysit you too much. Also you are able to switch compilers/interpreters easily, which you can't do with most ides.

Best compromise is emacs, it's one of the best text editors with many plugins for compiling/interpreting languages.

Ide vs text-editor is in the end mainly question of culture. Java-folks use ides, C-folks vim + (g)cc, lispers mainly have emacs with their interpreters embedded in it.
