i wish i had the drive to just write code for no reason like some people

i have to really want to make something, i guess. like i learned js when i wanted to make a chrome app and i learned python when i wanted to make a quick web site with django

i got all into emberjs when i wanted to make a sweet modal note-taking app that was like vim crossed with outlining but i never got emberjs to work right and it sapped all of my energy

maybe i should go back and try to make it with backbone or somethin

no. stop it. stop it stop it stop it. :sotw:

people have made good suggestions to you in this very thread but without fail you have ignored them and come back whining. i'm calling you a loving idiot not because you lack skills or ideas (both of which i am guilty of too!!) but because you're the most stubborn person i've come across in yospos and you refuse to learn. believe it or not i'm actually trying to help you even if i call you names. i'm legit mad irl that you keep doing this to yourself and you need to either stop it or get out. note that this is one of the longest and most time consuming posts i have made

okay so back to your q

no. see my point about you reinventing hello world in yet another flavour of the month web framework, like you always loving do

Milkie Galore posted:

you seem to be forever writing hello world 10 different ways or in 10 different languages. do something that actually challenges you and you might not feel so miserable about your achievements.

[...] i haven't coded anything in like a month and don't have any original ideas so i might as well try a new language or something

NO

i need to learn how to program good

then you need to stop doing things that you can already do. it will not improve your ability to program well. you are wasting time and effort and you will be no better off and will inevitably come back here complaining

ok heres another idea you had

abraham linksys posted:

my friend's family is opening a hookah bar soon, im hoping to convince them to let me make their website

don't do this. you can already do lovely little websites. this one wont be any different. youre wasting your energy.

similarly,

abraham linksys posted:

man i need to be coding something because if i dont code things i will never learn to code things better

this is somewhere between "wrong" and "only half the story". coding 24/7 will not make you code better because you are not challenging yourself.

ok summary so far:
- do not learn any more loving javascript web frameworks
- do not rewrite anything you have made already
- do not beg people to let you do lovely work you can already do

ok so what should you do then???

abraham linksys posted:

i know rotor said i should "learn basic theory" and the other recommendation is "learn a c# or java" but i only learn by doing and i need to do something

yes it can seem a bit like a catch 22 if you dont like reading theory! if you dont know anything about cs, you dont know any of the neat things that can be done, and they dont spring to mind when youre busy doing something else + make you think "i wonder if i could use that to do X". the more theory you know, the more neat things youll spot that you can explore.

abraham linksys posted:

thinking about coding something in Go

im reluctant to recommend go because nobody really uses it. however it does have a pretty cool concurrency paradigm if learning about concurrent programming sounds fun. personally id leave it till later. however

tef posted:

write a boids style flocking simulator, using one goroutine per boid

this sounds kinda fun!

what are some interesting things you've been thinking about recently? e.g. i like to listen to dj mixes and i think it's cool how tracks can be blended together. i wondered about how you might measure the melodic similarity/"distance" between two tracks using a vector space model like in computational linguistics. i've spent a few hours on and off exploring this idea and none of it required me to code anything!! it was cool. maybe ill code something up one day

what kind of things are you interested in? maybe i can recommend some high-level areas of cs you could read about to spark your imagination.

you shouldnt be choosing projects based on your current skills. "what can i do with node.js" isnt going to get you anywhere. find things that interest you in other domains and use your arsenal of computing knowledge to approach them. the chances are that someone's done something similar already which you can read about or play with!

i can't even begin to envision how it actually works

so try to work it out.

you're not going to learn anything if your reaction to something you don't already understand is "i dont understand that!!!!!! better not tax myself by actually trying to figure it out"

start with the parametric way to draw a circle: x=r cos(t) and y=r sin(t)
(recall that cos is just sin but 90 deg out of phase) and build it up from there

note that you can use different r vals in each if you want to draw an ellipse
or e.g. double up the t value inside one of the sins if you want a figure of 8
or knock one of them out of phase if you want to pinch the thing diagonally
or dampen the thing (recall the shape of e^-x as x increases) if you want it to die down as t increases

i suggest working with a simpler pair:
x(t) = A₁ * cos(f₁ t + p₁) * e^-d₁t
y(t) = A₂ * sin(f₂ t + p₂) * e^-d₂t

start with p1=p2=0 and d1=d2=0 and play with A1 and A2 and f1 and f2

the goroutines+channels seem really cool but i can't figure out why i'd use them, especially when it seems like so much poo poo goes wrong in concurrent programming

concurrent programming introduces a whole load of new considerations and possible pitfalls but using a language with decent high level concurrency primitives ameliorates that somewhat

java 7 added support for named groups in regexes e.g.

(?<foo>\w+)(?<bar>\d+)

is there some way to get the names of all the groups from a Matcher object if i dont know them in advance?

(like how i can get all the values of the groups by calling group(i) for 0<i<=groupCount() )

Shaggar posted:

java regex protip. group(0) always refers to the entire matched string. group(1) is the first one, and the last one is groupcount()+1. its loving stupid but thats the way it works.

the last one is groupcount(), note that i used <= not <

Shaggar posted:

tbh theres probably a way better way to do what u want tho.

dynamic regex group naming smells of p-language hackery.

i dont think there really is unfortunately, other than insisting the user uses numbers rather than names

basically anything that's not compile-time checked like using strings for poo poo is the worst

Using user-supplied regexes opens you to a complexity DoS

yes - though the user in this case is another coder, using [the output of] my code in theirs (think antlr,yacc,sablecc etc) so it doesnt really matter and theyre unlikely to do this to themselves and its not my problem if they do

you see, kids today learn to cycle easy. they have training wheels, safety helmets. in my day they learned to cycle on penny-farthings, and thats the best way to learn to cycle. i havent moved on since 1890, so why should i let them take advantage of progress - i certainly havent

people should learn from my mistakes by repeating them exactly, because my mistakes have been refined and polished over the years

who wants to learn javascript? making simple things that they can share easily and show to others? they should be learning to program in my home-brew hello world environment. what do you mean you want to do something fun? i never got to do that. i spent the first five years writing guessing games

Learnable Programming by Bret Victor

How to make programming learnable with examples and Shaggar-esqe opinions.

bret victor has a breathtakingly inflated opinion of his own importance and it bothers me slightly that people let him get away with it

the guy gave an hour long speech earlier this year in which he demonstrated some example programs hes written. this comprised half an hour of casually-scripted pseudo-spontaneous "oh i wonder what would happen if" moments designed to make using his software appear effortless and intuitive, followed by half an hour of thoughtfully spewing platitudes in order to elevate his computer programs into a fully fledged philosophy for living one's life

not content with this, he then, from his newly-erected visionary podium, without so much as a whiff of self awareness, compares himself to tesla and englebert, and suggests his personal life philosophy (wanting to improve software usability) is like 19th century feminist elizabeth cady stanton's desire to overcome social injustice

the mans a loving intellectual fraud and i wish people would stop cleaning his anus out with their tongues
