All programming languages are Lisps in disguise. However, Lisp is shit, therefore, all programming languages are shit.

I'm a medical tech call center guy.
Currently working on Linux+ to get started with that, and I'm on chapter 3 of C++ Primer Plus.

/g/ has been no help in picking a first language, so I just went with one. I heard it's easier to pick up new languages after the first, anyway. C++ is pretty fun so far. Just to trigger you more, I'm doing my exercises in Visual Studio.

>>60736499
how about some fucking programming
what is your go-to sort algo? everyone seems to use quicksort but heapsort seems to be the most efficient non-distributed algo right?

fugg get it together gee

pure book learning for c++ is really boring. Ive made a few programs with the skills ive learned (a wip text game with dynamic battle system being my best so far). What else can I do? I do the /g/ challenges as I learn how to do the underlying sill

My main is still Windows 7 because of games, I have a laptop with centos that I'm working on so I can remote into it from anywhere and do my coding there. I wanna end up with a RHSE, and I heard centos is the closest thing to a red hat server.

Well maybe go for python3 then instead of such outdated bullshit?
python3 even has printf-like syntax, which make it far more superior

im making a retarded ass program with no purpose in it except for practice.
i've got 2 tBoxes for input values. Then the listbox fills with 1000 random numbers between those two values. I export those values as a list and convert them to their ASCII counter values. After that, i print them out with speech synthesizer using a cute grill voice. Only thing I'm missing is some API key that would look for coherent words in that long ass string...
see sharp

>>60738854
what you using for the cute grill voice? get the terry source for gw
p sure you could also find a dictionary file with common words

I used a few apps like this when I had to learn notes up to the twelfth fret! Looks stellar, I would love to see the source.

>>60737968
I don't believe this at all.

>>60738592

Print is a function in python3, and it's syntax requires parenthesis.

The right form is:

print("blah blah blah. I'm %d yo", age)

how do i make successfive while loops in a bash script?
I can make a single "counter" while loop (x=1 then ticks up), but I need to change the command at different x values.

here is an example of a two nested while loops that print from 00 to 49 using two counters, the while loops use conditionals syntax close to that of C:

x=0; y=0; while ((x<5)); do while ((y<10)); do echo "$x $y" ; y=$(expr $y + 1); done;  x=$(expr $x + 1); y=0; done

>>60740626
Thank you, but not exactly what I'm looking for.

I need to run different commands at different iterations of a counter e.g. run Command 1 as long as x<40, run command 2 when x=40, back to command 1 until 80 etc.

I'm trying to use xdotool to download a list of documents, but some of the links are "bad links" that upset the macro, so I need to skip that macro on the iteration that corresponds to that "bad link".

Hi, I'm currently using Kotlin in a college project. I am trying to delete endings of Strings, they always end with (number).
e.g.: "Nirvana (2)", "Aargh (102)"

I am trying to use a regex to replace the number surrounded by parentheses with "", but that does not work:

 "Nirvana (2)".replace(Regex.fromLiteral("\\(\\d+\\)"), "") 

Also:

 "Nirvana (2)".matches(Regex.fromLiteral(".*")) [\code]
Always returns false, but shouldn't that match with everything?!

Does anybody know some...solution? I really can't figure out what I am doing wrong, fck

>>60740825
it's

regex.matches(input)

not the other way around. https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.text/-regex/

Trying a trivial example like .* and noticing it resulted in absurd behaviour is clever, so kudos for that.

>>60740799
This is something I do routinely if you elaborate on what you intend on doing I might be of some help, although you shoulda gone with this question to the fglt thread, your question doesn't sound like homework so it is okay I guess.

One more thing, I think you're knocking the wrong door here with xdotool, wget or curl and scraping web pages using grep/sed/awk for links is definitely the way to go if you're out to mass download stuff off of the web. Python does this quite cleanly too, but I'll assume you are not very knowledgeable with that and go down the shell road.

>>60740930
Wait no, String appears to have matches and replace methods that accept regexes, yet your examples fly out the windows. Watfug? Kotlinfags will defend this!!!

>>60740974
Wtf. This was not my intention

>>60740930

Thank you, I thought the replace function also worked with regexs.
But it also does not work for me (using Kotlin 1.1.2-4):

Regex.fromLiteral("\\s\\(\\d+\\)").matches("Nirvana (2)")

However, I just solved the Problem by creating some helper method in Java thats using the same regex. Strange

>>60740943
Thank you for the reply.

Yes, its a personal project to try and get some documents from a website that I only have access to until I graduate uni (practical law).

I have no experience with any kind of programming whatsoever.

The site uses javascript to give you the dialog box to download the file, so with no experience, xdotool seemed to be the most direct option.

Turning off javascript makes it so that there is no dialog box to the pdf that I need.

Right now I am using a while bash script with a counter, and on every iteration it goes something like:
x=1
while [ $x -le 40 ]
do
xdotool key ctrl+Return
sleep 0.1
xdotool key ctrl+2
sleep 12
[Mousemovements/clicks to download the file]
xdotool key ctrl+w
sleep 1
xdotool key Tab [ie select the next link]
sleep 1
echo "Downloaded $x documents"
x=$(( $x + 1 ))
sleep 3
done

The problem is that there are some "bad links" that do not open new tabs, change the focus on the same page, so that the focus on the next document is lost.

Also the ctrl+w closes the whole window on a bad link.

Sorry for the whopper of text, I genuinely appreciate the help that you're giving/may give.

The back slashes are regex escapes?
