I have roughly 7 mb of html
what do you suppose would be a good method of searching it for strings?
I was thinking of taking the first word of input, returning all those results, take the second word and only search those first set of results and so on to make it as efficient as possible
Is that the best way to do it?
>>55545627$ grep PATTERN [FILE]
Take 2, this time without that stupid newline.
>>55545627
Nokogiri should do it really nicely if you want to get rid of the HTML noise.
Example:require 'nokogiri'
require 'open-uri'
puts Nokogiri::HTML(open("https://boards.4chan.org/g/thread/55544625")).text
This will put the text of the entire thread in your console. (Not very readably, but without any HTML elements)
You can grep the result, or use a Regex from Ruby's REPL.
If I have a Juction Table with 2 Foreign Keys, do I need to add this IDs manually or they're automatically added when I insert something in the other tables?

>C exploitable memory requires you to miss a single detail somewhere

>>55546287
So what you're saying is that you're too shit to use a language like C safely?
>>55546340
Correct.
I am OK with writing things, but I would never offer to write something people would rely on for security purposes in it.
>>55546335

>>55546379
I'm not saying everyone is, I am saying that >>55546153 is untrue. C can easily fuck someone up in ways that is impossible in other languages.

>>55546399
>>Double free

>>Unchecked buffers

>>Raced mallocs
...what?
As I said, C is just as safe as the majority of the languages.
>>55546440
Throwing an exception isn't the same as memory corruption.
>>55546495
The C standard does not say anything about memory corruption. It is not the language's fault that you are using an unsafe implementation.
>I-it's not the languages f-fault!
Sure, but apparently everybody is too fucking stupid to use it, because every sizable C project results in extreme & dangerous vulnerabilities.
>>55546617
That is why c++ has the string class.
>>55546617
>Hurr it's the languages f-fault that people are retarded!
For a language to be safe it isn't enough to be possible to program in a safe way, it has to make it desirable other than the safety (ease, performance, etc.) and the community has to support idioms that reduce the chance of doing something unsafe.
>>55546649
An example of something C doesn't have
how do you make two classes in separate header files include each other for mutual friendship.
>>55546649
>>55546675
A string type would go against the spirit of C.
>>55546660
Either only C programmers are retarded, or the language is more dangerous.
>>55546715
Again, see >>55546511
Nothing to do with C programmers.
>>55546649
Strings are truly underappreciated.
>>55546511
If it's so easy to do something outside of the spec that almost every sizable program written in the language does it, then you have a problem.
>>55546869
Doing something outside the spec has nothing to do with hat I said.
>that almost every sizable program written in the language
Not true, I hope at least.

How many of these are not written in C or something that uses C's memory management?

For the rest of them it could be solved if they followed my advice above.

careful, his might be too broad, since many compilers/interpreters are in C

That statement encompasses probably 95% of programs. Of course most most vulnerabilities occur in most programs.

Learning my first programming language (Java). I'm retarded, why doesn't this code work. It's telling me I can't make a static reference to the non-static field "printArray".
>>55549200
You have a static function and you are trying to modify a per-instance field. The per-instance field doesn't exist until you make a new object with 'new' and you are trying to reference it in a function that exist as soon as the program compiles. Tell me how that's supposed to work.
More likely than not you don't need to make the function static.

>>55549200
>Learning my first programming language (Java)
Don't learn Java. Stop while you still can.
>>55549200
You need to either make the variable static, or declare it inside the main function itself.
>>55549239
shit, just realized that.
>>55549200
Make the variable printArray static. Or you can do this.class Listing {
...
int printArray;
public Listing(String args[]) {
// put real main function here
}
public static void main(String args[]) {
new Main(args);
}
}

How can I make this faster? Exercise 23 on project euler. My factor function could probably be better, but removing the nub check (obviously making the results wrong) only shaves of 20 seconds of the total 2m 7s time so there's probably a bigger optimization I can make hereimport Math
main = print $ nonabunduntsums
nonabunduntsums = sum $ filter notsumtwo [1..28123]
notsumtwo num = null [x+y | x <- [1..num `div` 2], y <- [num-x], isabundunt y, isabundunt x]

New to C Programming. Having some issues with for loops within other for loops. I am just curious as to why this doesn't print out everything inside the for loop (x=0, x<s, x++) 4 times?
>>55550404
You're using the 'x' variable in the inner loops.
It sets 'x' to equal 10, so it's going to exit the loop after the first iteration.
Use a different variable for the inner loops.
>>55550427
Ahh shit yeah I see. Thanks a ton been struggling for the past hour trying to figure out why it wasn't printing out!
>>55550393
What the fuck does it mean to "compose functions?"
>>55550476
Calls function a, then function b with what a returns.
So basically b(a(x)), but it creates its own function to do that.
How do I into Python?
>>55550447
It's a very common beginner mistake. Dunno why but a lot of new commoners try to use the same variable for all loops.. With the route you're going it should look something like thisint x = 0;
int y = 0;
int s = 4;
int num_of_spaces = (s - 2) * 5;
for (x = 0; x < s; x++) {
printf(" ___ ");
for (y = 0; y < num_of_spaces; ++y) {
printf(" ");
}
printf(" ___ \n | ? |");
for (y = 0; y < num_of_spaces; ++y) {
printf(" ");
}
printf("| ? | \n |___|");
for (y = 0; y < num_of_spaces; ++y) {
printf(" ");
}
printf("|___|\n");
}

Federal laws state you have a right to own a gun, not a right to shoot it. When and how you can shoot it depends on your state.
That said, if allowed to take a strictly literal word meaning interpretation of my state's justifiable homicide laws, that might include shooting someone who is trying to blackmail you. But you'd have a difficult time proving that happened at all in court anyways. Also, I'm not a lawyer, Anon doesn't live in Washington, and to my knowledge, nobody uses the literal word meanings of laws precisely because that same law I am quoting if taken in a strictly literal sense would allow a person to shoot someone for committing tax evasion if they were committing it in their presence.

Ruby, it was a tongue-in-cheek "Haha, America!" kind of thing. No need to analyze it.
We really need to get rid of the cockroach infestation in /dpt/.
I want to improve this pasta, to make it more accurate and more helpful. The goal is to help newbies started on picking a starting language to learn programming. It is not meant for people who already know programming, or people asking about "what language to get a job".
Please criticize. Thanks.
im learning python right now, specifically web scraping with beautiful soup and im trying to get some data from html with really shit formatted tables
so I have a list with a structure of[a1,b1,c1,d1],[a2,b2,c2,d2],[a3,b3,c3,d3]
etc, and what i'm trying to do is save the a and b values of each index of the list into a seperate variable
how would I go about extracting these values?
it's code for a runescape world data scraper, i scraped all the table rows first withdata_rows = soup.findAll('tr')[1:]
which skips the header row since i don't need it, then I find all the standard cell data withserver_data = [[td.getText() for td in data_rows[i].findAll('td')]
for i in range(len(data_rows))]
Your comments, suggestions, and criticisms for >>55550915 are appreciated.
>>55549553
nub is O(n^2) in the number of elements in the list, since it has to support things which are Eq but not Ord. It is possible to do nub in O(nlogn) for ordered types.
IIRC sum is not strict, so you may want to write a custom strict sum (using bang patterns or seq)
>>55550915
Perhaps you might reference a few of the up and coming languages as options?
Like Rust, Go, Hack, Scala, and Julia.

Hack is backed by facebook there is a good chance it'll grow and get adopted.
Scala is starting to be used by companies like twitter, linkedin, and intel.
Julia is gaining traction in the scientific community.
I do not see how your reaction image is warranted?

I know of no one other than Facebook that uses this.

Eh... just use regular Java. Or Clojure.

I don't know of anyone who uses this.

Ugh. Two days have passed and I still cannot decide what should I use: React, React+Redux or Angular2.

I believe we may of accidentally synced up here..
Julia is starting to be used where people would previously use python + Numpy / Pandas or R.
I do agree though that Hack might have a very tough time seeing adoption. It's trying to replace php and is a big risk for companies that are used to running the old "stable" dinosaur that every web dev can grudgingly work with.

dynamic programming ≠dynamic typing
structured programming is not the opposite of dynamic typing (Ruby and Python have both)
neither are really "families" since the languages other than C are all the same paradigm (imperative+oop) and the languages are all based on the same core design
>>55551358
Facebook is the main user of Hack, but I've heard of other companies moving to it from PHP
Go's huge with Google, Twitch.tv, etc.
Scala is the most popular (lots of JVM users with startups developing for Android or people moving away from Java)
Erlang is probably used at any major telecom company, ISP, phone carrier, etc.
>>55551362
What is the best nomenclature that I can use to group the Python family and the C family?
>>55551393
Imperative programming languages.
>>55551313
Baseline Julia performs very close to C in terms of speed without the extra work you'd need in python.
Julia is built with parallelism in mind. The base functions / types reflect this.
Packages in Julia come directly from github and doesn't have the schism issue that python2 / python3 has.
Anyway, at this point in time your comparing a mature fully realized language and a infant language. There is plenty of time for any issues to be resolved and for the ecosystem to catch up.

Compiled vs Interpreted.
Statically typed vs dynamically typed.
>>55550915
the use of dynamic languages in academia is more about flexibility and convenience than it is about their being suited for heavy computations (because in fact it's the opposite that's true; compiled static languages are better suited for heavy math because their compilers are capable of heavier optimization).
If you can't figure out what this regex does, you need to leave /g/ forever./^[a-zA-Z0-9- ]*$/
>>55551433
This means taking Java out. But thank you, I will use this.
>>55551442
Thank you. Will edit accordingly.
>>55551442
and in this case "academia" is fairly limited to heavily computational tasks that are mainly composed of arithmetic. basically, other than AI or ML research and a number-crunching for experimental data Numpy/Scipy aren't useful
>>55551299
Hack doesn't seem to be actively trying to replace php. Facebook mostly made it to assuage the horrors of having a shitton of PHP code (see also: javascript & flow). It's a major advantage of hhvm, so it was made public.
What is everyone's favorite language for certain types of projects?

Everyone's favorite language for certain types of projects is indisputably Java.

So you want to learn programming?
Pick a starting language. For beginners, there are generally two recommended "programming families" that you can choose to start learning:
-Dynamically typed/interpreted programming languages, such as: Python, Perl, Ruby
-Statically typed/compiled programming languages, such as: C, C++, C#
These are amongst the most popular languages in use worldwide, including 4 from the top 5. Both approaches are perfectly fine, and well-documented.
-Dynamically typed programming may be a bit more flexible, convenient, and forgiving, and thus it is more popular in academia.
-Statically typed programming is a bit more suited for making general applications, and thus it is more popular in industries.
Cannot decide? Flip a coin.
If you choose dynamically typed/interpreted programming, you may want to start with Python. It is very easy to pick up. Here are some good sources:
http://www.learnpython.org/
http://learnpythonthehardway.org/book/
http://www.codecademy.com/en/tracks/python
If you choose statically typed/compiled programming, you may want to start with C, then pick up C++. C is very well documented, and teaches many universal programming concepts. C++ is based on C, and adds new concepts. Sources:
For C:

>BUT I WANNA START WITH [language x] INSTEAD!
Sure, if you like. But the languages shown above are considered very good for beginners.
>BUT I WANNA MAKE iPHONE GAMES!
Learn Objective C and/or Swift.

>>55551462
agreed. and i prefer to work with C++ even for AI/ML work for performance reasons, but i don't speak for the community, and i don't personally require the flexibility that some surely do.

I've been interested in generating colourschemes for a while now.
I know that the basic way of generating a colourscheme is to generate a rainbow circle and then superimpose a sample vector (see http://paletton.com/ or adobe kuler)

But other than that, online tutorials will never teach anyone as much as real books.

He was right about recommending stuff like bstr to people. C strings are the cause of security holes.
