>actually believing there's nothing wrong with BASIC
"It is practically impossible to teach good programming to students that have had a prior exposure to BASIC: as potential programmers they are mentally mutilated beyond hope of regeneration." -- Edsger W. Dijkstra
And today you can replace BASIC with Python in that quote.
>>51464666

this
it's truly cancerous to tell people to learn python as their first language
>>51464694
not him, but basic is where the "goto statements are bad" meme came from because they are used so much in basic.
judging by the previous threads, looks like people actually cared about our opinions, and, even better, are actually building things with Go.
it's nice to know that, while people here shill for Lisp, functional programming languages, C# and C++, other people actually do things.
>>51464707
Do Python programs also use goto all the time then?
Taking a stupid programming class for my ME degree next semester, learning C, what am I in for?
>>51464720
no, there is no goto and there isn't even labeled break/continue because guido thought it would be too difficult for python users to cope with
>>51464720
No, I don't think python is bad.
It has it's place, but I think basic doesn't have anything good about it.

Can I use typeid like this? I tried Googling it of course, but all the top links on typeid are about random abstract cases on classes.char *example = "Hello world";
typeid(example) == typeid(char *)
Will the second line evaluate as true? I know it will for simple types but I'm wondering if it's different for pointer types, etc. Would typeid(int*) be different than typeid(int)? Thanks for any help, I know I could try it myself in a compiler but I don't want to be misled to some minutiae.

nope looks fine to me
>>51464935
I knew it looked funny
>>51464929
It returns a type info object and as thus it is not guaranteed to be equal even for the same types.
Use:typeid(example).hash_code() == typeid(char *).hash_code()
or:type_index(typeid(example)) == type_index(typeid(char *))
And int * isn't the same type as int.

Hi tpg. I am thinking of learning to program and I am interested in C++. Am I a total moron for wanting to learn C++ first/at all?
I have always loved small, efficient single exe programs on windows. things like sumatrapdf, utorrent and notepad2. I also want to learn about reverse engineering and assembly, etc. to use things like ida pro and understand step by step what is happening.
what is the best way to go about learning this stuff?
>>51464863
>>51464933
I just went with a picture of a synthesizer instead.
>>51464995
which synthesizer?
>>51464989
Learn C first, especially since you said you're interested in RE and assembly. And if you really want to learn C++ later you'll have a foundation.
>>51464978
Thanks mate

String, memory and pointer hell, but it' s a good language.
>>51464883
KPL (kernel programming language). It's a language designed by some professor at Portland State University to make teaching operating systems classes easier. It targets an emulator called Blitz that uses its own custom 32-bit RISC architecture. Also, you can't compile the emulator to run on 64-bit anything because the guy who wrote it literally casts int to pointers.

inside public buildings like schools and whatnot you keep your shoes on. but in your own home it's more comfortable to not have fucking shoes on and you don't get the dirt inside your house.
>>51465104
The home should be a clean and comfortable place. Also there's this thing called carpeting.
>>51465122
>it's more comfortable
Why not wear comfortable shoes?
You can put slippers on if you want, I don't give a fuck. Slippers exist in America. People wear them inside their homes.
>>51465137
>Carpeting
Hardwood floors are far more popular in modern houses. They look nice and are extremely easy to clean (which is far better if you value cleanliness).
>>51465156

>>51465175
I'm wearing shoes right now, they're quite comfortable. They're not very noisy either. Not sure what 3rd world shithole you're living in that you can't get a comfortable pair of shoes in.
>>51465156
wow is this for real
people wear slippers in sweden but just socks/barefoot is probably by far the most common. no one wears outdoor shoes indoors

If you're going to be flopping all over the furniture, go ahead an take your shoes off. Is this hard to imagine? Some people walk around in their socks too. Do whatever the fuck you want, it's a free country.
Obviously if your shoes are muddy or you're stepped in dogshit or something you'd take them off instead of tracking it around the house.

pleb here, learning hashes on c++
/g/ so when the pizza guy asks for my phone number, he's looking for my information on a hash table, or is it usually something else?
How useful is this data structure for casual businesses?
i live in sweden, i've already seen it all. this guy want schools to give a trigger warning to students when there's a white heterosexual couple in some book.
https://www.youtube.com/watch?v=Nunl7Ec5bEk
it amounts to some childish faggotry/trolling, not worth paying attention to. just do your grown-up stuff and don't let you'reself get trolled this easily. and like with the "refugee" crisis, people will start to wake up and these faggots will get rekt. the leftist "environment" party for instance might not make it to the riksdag next election and the feminist party never got into the riksdag in the first place, while the based sweden democrats have become the biggest party in sweden.
>>51465442
another term for a hash table is a dictionary. that should answer your question
>>51465442
it's probably a SQL database wrapped in some other language. it's very unlikely that they're using hashtables lol
>>51465481
Well the databasse results could very easily be stored in a hash table
>>51465295
The "type" of a function is just what it returns. If it's void, it doesn't return anything.
E.G. you can't assign a variable to the result of the function, or add it to a list, or w/e.
But you can still manipulate global variables from within that void function, so it's still possible to have it change data elsewhere in the program
>>51465442
If your pizza guy is a hardcore programmer gentoo-specialist, he'll look you up by hash table. It's very appropriate for that.
>>51465455
that sucks senpai
>>51465342
There's no char type. You can store it as a number, but I don't know if it saves any memory.

Because C is clean and very easy to maintain if you're not a fucking retard. Like you apparently are.
>>51465658
So you were a C programmer talking about maintainability after all.
>>51465658
>C is clean and very easy to maintain
This is just retarded. C programs, unless they are vary tiny, are filled with unnecessary hacks, making it completely unmaintainable. It is lacking basic construct blocks and features, which would make you think about your actual program instead of memory leaks.
>>51465792
You are just spouting shit.
C is just as maintainable as any other language. You can easily modularise code and limit interactions between them and write everything in a structured. Not everyone is some Java retard who tries to shoehorn "OOP features" into C.

Creating a license like this is pointless. It's not enforceable in court, because it violates the discrimination laws of most countries (or at least the United States, which is the only country that truly matters in the tech industry). Moreover, anyone can simply say they're bisexual, fork a repo, re-license as MIT, and no one would be able to stop them. And even if one didn't want to call themselves bisexual, and all of the courts were completely corrupt and only enforcing discrimination laws when it applies to non-whites, the license still wouldn't be able to stop a white heterosexual male from copying, re-licensing however they want, and selling/redistributing the file. Why? Because he can act under a corporation. The corporation owns the code and the licenses, and the corporation does commerce. The corporation is a person, a separate legal entity from any person(s) running the business associated with it, and as a person, it has no skin color. In fact, it doesn't have a body.
If you want to release free software, that's fine. If you want to ensure that the source code gets contributed back, there's tools for that - the GPL. If you want to make it easy for people to use in their existing codebases regardless of whether they are free or proprietary, there are tools for that as well - MIT, Modified 3BSD, and Apache. But don't pretend that you can do the world a great service by getting more non-white/heterosexual/males to do more programming by half-assing the GPL license only for white heterosexual men.
>>51465894
Oh, and one last thing. Can anyone prove another person is white before a court of law? Aside from the fact that there isn't any "white" gene, there is debate over what makes one person "white". Some people follow the "one drop rule", which holds that a person is not white if they have any ancestor who was not white. Some people say that people from certain southern European countries are not white. Some people have even claimed that the Irish are not white. There is no standard legal definition of "white", and the burden of proof would be entirely on the prosecution for claiming someone is in violation of their license agreement.

If you think C++ is you're goal, then no to both. By learning it first, you'll be freed from having to unlearn lots of bad habits from other languages--especially C.
As to learning it at all, Ofc no one can predict the future, but C++'s outlook is better than ever. It's industry use keeps going up atm, and it's getting both easier to learn and faster as a language.
I started with assembler, then learned C, then C++, then a few other more abstract languages such as Python. For all the systems that I care about (large projects where performance is king), C++ winds up being my goto language.

i actually think that having learned python first would be a great hindrance to learning java and other programming languages. see >>51464666
all the basic control flow with if/else, loops and such is pretty much the same (except java has the proper, traditional for loops which python doesn't). and java is strongly typed which is a good thing and the IDEs are far better. you learn nothing with python that you can't learn better with other languages.

Yeah, but they pretend to think otherwise. They literally make TV shows called "girls can code" to try to "prove" otherwise.

>>51464989
No, C++ is great. I keep going back to it. Don't listen to Cfags, anyone that learns C first writes shitty C++ for the rest of their lives. That's assuming they even code in C++, most of them just stay in C and reimplement C++ features all day (like vtables with function pointers to get around the fact C has no polymorphism)

Actually Dijsktra was talking about the BASIC that existed in the 70s, which was based on using line numbers and GOTOs everywhere. Visual Basic on the other hand was a perfectly fine and modern language, which all the conditional statements and loops you would expect in any structural language.

Let's be honest now. Why would it be worth learning to use a text user interface text editor like vim/emacs?
Sure, after getting used to, they allow you to write and edit text a lot faster. But the actual process of TYPING isn't the main part of the work in making software. Don't you spend a lot more time reading code, navigating around code, thinking and planning than typing?
So why wouldn't you use an IDE or GUI text editor that allows you to hop quickly between calls and definitions, etc?

Nice meme, but GNU/Linux has today better font rendering than Windows and OS X, especially on non-HiDPI displays. Most importantly, it can be tweaked as you like, unlike proprietary software. Feels good man.

vim and emacs are excellent at that.
vim with ag (silver_searcher) + fuzzy searching and vim's built-in tag/jumplist is the best code navigation experience I've ever had.
>>51468051
>GNU/Linux has today better font rendering than Windows and OS X
lolno
better than OS X but not windows
>>51468028
because vim does that?
>>51466877
How does it follow? At the end of the day you're still writing code that has to live on the processor. How is being a few steps closer to that reality harm you when you start to learn coding harmful? How does being more detached from that reality when you start to code help you?

Because both Emacs and vim allows you to do exactly that.
I use vim for development, I have plugins that allow me to do
>code completion
>quick definition navigation (aka jump to method/class definition)
>parse compiler/interpreter output so I can use it for linting and for jumping straight to compiler errors/warnings
>front-end for GDB, allowing me to debug code while following the code within vim
I've seen plenty of people do the same with Emacs.

YouCompleteMe is elder god tier and helps in fast fuzzy autocompletion.
It provides your jump to declaration and definition too.

I see all kinds of 'fences', 'lock-free', 'hazard tracking', 'workers', 'jobs' terminology stuff, but it's too much for my lizard brain

>>51468171
>I see all kinds of 'fences', 'lock-free', 'hazard tracking', 'workers', 'jobs' terminology stuff, but it's too much for my lizard brain
Fences = memory barriers, you wait for data to be pushed to actual memory
Lock-free = concurrent algorithms that are fast because a thread doesn't need to fight over a lock with competing threads (see atomic compare-and-swap)
>workers/jobs
workers = threads, jobs = a task that needs to be done
is it possible to code in c and use python gtk at the same time? if yes if I compile it with mingw on linux can I use the compiled stuff on windows without having to worry about installing additional stuff on it?

What I meant is that GTK+ is written in C. You can make GUI applications with C GTK's C API, instead of using some complicated mix of Python and C.

10. By "feelings of inferiority" we mean not only inferiority feelings in the strictest sense but a whole spectrum of related traits: low self-esteem, feelings of powerlessness, depressive tendencies, defeatism, guilt, self-hatred, etc. We argue that modern leftists tend to have such feelings (possibly more or less repressed) and that these feelings are decisive in determining the direction of modern leftism.
11. When someone interprets as derogatory almost anything that is said about him (or about groups with whom he identifies) we conclude that he has inferiority feelings or low self-esteem. This tendency is pronounced among minority rights advocates, whether or not they belong to the minority groups whose rights they defend. [...]
12. Those who are most sensitive about "politically incorrect" terminology are not the average black ghetto-dweller, Asian immigrant, abused woman or disabled person, but a minority of activists, many of whom do not even belong to any "oppressed" group but come from privileged strata of society. Political correctness has its stronghold among university professors, who have secure employment with comfortable salaries, and the majority of whom are heterosexual, white males from middle-class families.
13. Many leftists have an intense identification with the problems of groups that have an image of being weak (women), defeated (American Indians), repellent (homosexuals), or otherwise inferior. The leftists themselves feel that these groups are inferior. They would never admit it to themselves that they have such feelings, but it is precisely because they do see these groups as inferior that they identify with their problems. (We do not suggest that women, Indians, etc., ARE inferior; we are only making a point about leftist psychology).

how is php related to bootstrap?
>>51468564
I guess you can let PHP generate bootstrap elements?
Does anyone in here know shit about Ada? I'm trying to learn it and my first exercise is making a matrix calculator, but I'm stuck in making the ADT (I know there's a library, I want to implement the matrix myself). I want the record for the matrix to include the row count, column count, and of course the contents of the matrix which will be a 2D array. I want the matrix to be dynamically allocated, but of course there's a lot of issues with that. I'll go into more detail but I want to know if you guys would mind.
>>51468171
> how do I into mt/parallelism?
Get a good book. Avoid anything that claims to be suitable "for dummies" or which suggests that the learning process will take a given number of days.
But before any of that, you need to be a reasonably competent programmer. The reason I say that is that for concurrent programs, trial and error will not work. Different runs of the same code on the same inputs can produce different results unless you take all of the necessary steps to ensure that they can't. If you make a mistake, the program might coincidentally work 99 times out of 100, i.e. it will pass all of your tests yet not actually work reliably (and good luck trying to debug such problems).
speaking of bootstrap, how would i make an image disappear when screen size is small? or when i resize the browser window to a smaller size, i want an image to disappear, and then reappear when its big again
>>51468674
There isn't really a thing in bootstrap where you can say that when a screen is less than x amount of pixels an image has to disappear.
There is http://getbootstrap.com/css/#responsive-utilities-classes, which will probably get you far enough.
You'll have to build something that does that yourself, which I've seen done before done by a PHP guy I've worked with, but I'm not a PHP guy.

Of course a 2-dimensional array isn't the same as a Matrix- It might be a subtype, but you have to declare it as such.
