Convince me NOT to learn and use Ruby.
And.... Go!
>>54235612
it's shit
It would be good if youd did something instead of shitting in your pants so go for it
>>54235631
In what way?
It's one of the greatest languages ever created.
There is no reason not to use it
It's not really used by big corps.
I started as a ruby dev and only found shit startups that would never pay me in time.
desu you can make a lot as a ruby consultant broheim. I know guys with 5-10 years xp that make 150-200k
>>54235612
The best way would be to learn it and then discover your own reasons for not using it.
Definitely don't use *rails* for new projects now that better systems are available, but ruby as a language is still great for scripts and text processing. It's basically what perl should have been.
>>54236250
What if I don't want a job and only want to use it for practicality?
>>54236581
This tbqh.
>oh I want to download all the images from a page
>Oh I can literally just use the "image_downloader" gem and use the function to find all image files on a page
It's the best language desu.
Use it. Love it
>>54235612
Its a really fun language, and learning it will make you smarter.
Some downsides I didn't see people mention: if you or the people you work with are undisciplined, codebases can quickly become nigh impossible to maintain. Ruby will happily let you do some really stupid shit.
It's also shit for reasonably large distributed systems.
If neither of those bother you, I say go for it.
>>54236581
this.
>>54237522
Sweet. Any good resources you could recommend to have a read through to understand best practices?
Don't learn both Ruby and Go. Just Go will suffice
>>54237766
My first stop when learning a new language is always a style guide. Gives a nice overview of the syntax and a quick reference for what to do and not to do in the language. Just Google Ruby style guide and that should get you it.
Other than that, I think I did a couple basic tutorials and then started building shit in it. Conference talks are also a good reference for mid to higher level concepts.
>>54237924
Thanks SENPAI.
Ruby looks neato. I'm coming from C++ so it's definitely a little different but looks much nicer
>>54235612
Hipster bullshit
>>54238328
Explain.
>>54236581
What better systems are you speaking of?
>>54235612
Ruby is pretty cool but the amount of syntactic sugar it has can lend itself to horrible looking code. That, and it kind of rewards solutions that are complex and are hard to grasp but short in character count.
Ruby is the best
It'll force you to learn proper OOP, so I'd say it's definitely worth learning.
Most people never bother learning OOP well, so it'll definitely give you a competitive edge.

According to that autist fucking everything is "harmful"
Also IDC about rails
>>54237924
Using a style guide as an overview is definitely great advice, and while I think most ruby style conventions are great, it still drives me nuts how every ruby style guide says not to use numbered capture groups in regular expressions.
Under the assumption that the "important" part of some text processing is the regular expression rather than the surrounding code, I say it's *always* better to optimize the regular expression for readability rather than the other stuff, and a shorter regular expression that uses ([a-z]+) instead of (?<whatever>[a-z]+) is much faster to parse and read. Just assign the capture group to a different variable immediately after the match to be safe. Also, if the regular expression is too complicated to keep track of using numbered groups, then adding names to the groups isn't going to magically make it more readable.
>>54238378
Truly the spiritual successor to perl. However, unlike perl, you at least *can* have clean-looking ruby code.

mruby still dead, rubinius is a joke. rpgmaker now using javascript instead of ruby.

>>54241460
perl 6
>>54241480
perl 6 is still irrelevant. everybody uses perl 5
>>54241460
You get to use a well-designed language that does all the same things but is relevant outside of "muh UNIX" culture
>>54241547
well, I just answered your question
> are there any reasons to use ruby over perl?
why, because after all the year perl 6 is still a meme. Just like python 3.
meanwhile ruby is growing just fine, we may have JIT + type annotations in ruby 3 and more.
>>54241610
Perl 6 changed the one thing that managed to break out of the shitty language and become a lasting legacy: PCRE
Now it should be P5CRE...
>>54241597
just because your hipster startup doesn't use perl doesn't mean it's irrelevant today

yeah python 2.7 is too (they claim "we just maintain it, no update" though)
>>54241675
Sorry, but the fact legacy applications and design-by-committee UNIX install scripts use perl doesn't mean it's still relevant. One could say the same thing about visual basic, but that doesn't mean that it's relevant or that people should be encouraged to use it.
it's made of lo-o-o-o-ve

>>54241992
Reminder that nobody (even in this thread) is disagreeing that rails is cancer.
Ruby as a language is not the same as rails, though, and has plenty of redeeming factors if you use it, as said earlier, for scripting, text processing or one-off web scrapers.
>>54242112
Agreed. I use it for managing my Windows (through unison) backups and doing basic stuff with the rb-inotify library on Linux. It's a very easy little-hassle language when you just want stuff to work
Convince me NOT to learn and use Rails.
And.... Go!
>>54242269
https://twitter.com/dhh/status/695272044024487936
>>54242269
Your time is better spent learning Go if you want to write web servers. Or learn to use node so you can do server shit while improving your JS skills. If you really want to use ruby web frameworks go for something lightweight to begin with like >>54240353.
If you don't know ruby already and want to do web stuff, then you're better off starting with a different language. If, however, you already know ruby and want to learn rails to get a job at a hipster startup, then knock yourself out.
>>54242269
Just imagine how much money github could start saving in power usage and hardware if they switch from ruby to a language that's actually efficient.
>>54235612
Ruby is arguably the most beautiful language you'll ever see.# creates array from 1 to 100 and return the second last number of that array (= 99)
Array(1..100)[-2]
#sum of an array, but leave out 11
[1,3,5,7,11,13].inject { |a,b| a += (b == 11 ? 0 : b) }
# print out all of the files in a directory
Dir.glob('./my_cool_directory/*').each do |file|
puts file
end

I tried using the image_downloader Gem but it doesn't work even with default documentation example code.
It depends why you want to learn. Everyone should know a scripting language, just for convenience

>choose python or ruby
I like ruby more, honestly.
>>54243023
no fucking way is it that simple!
>>54242920
for interacting with database search for the sequel gem. Way better than that activerecord crap
>>54243052
use nokogiri to fetch all those <a> tags, then using whatever http client you like?
Makes it pretty easy to create website applications or SAAS
>>54243147
More like, use open-uri to get a page's content, then use a regular expression to find src attributes ending with png, jpg or gif, amirite :^)

>Ruby will happily let you do some really stupid shit.
Which is my main reason for not wanting to work with it professionally or with anyone else. For a side project/for fun? Sure, if it fits the situation. But I will NOT program Ruby with a "team" of other developers. It NEVER ends well when it comes time to debug/optimize.
Kind of a moot point for me, though, since my work is 60% interfacing directly with Hardware.
>>54244508
So what's the answer?
>>54244742
For a one-off scripts to rip porn videos from streaming sites, why bother downloading and learning to use an HTML framework when it would be much faster to use regular expressions? Maybe not the best example with how good youtube-dl is these days, but still the point is that there are plenty of times when you simply don't care about the stability of the solution and you just want something that works right at the moment.

Damage control from nervous rails devs, everyone.
>>54247190
Nah it's more about NEETs calling shit a "sjw" language.

Ridiculous tbqh.
>>54235612
First, you tell me what ruby is even used for.
>>54247240
Scripting
>>54235612
Pic related is your typical rubyista / code artisan / sjw degenerate
>>54247376
This is a retarded argument.
Just because someone uses something doesn't make it bad. Why don't you talk about the actual language than "xD it's a sjw language"?
This person probably doesn't even use Ruby.
>>54247470
I never said the language was bad in my post, did I?
I just said that "coders" like pic related are infesting the ruby/js webdev scene.
If you intend to get a job (or contribute to OSS on sjwhub) writing lang related, prepare to work and interact with these types of people.
If OP considers this to be a downside, then it's relevant.
>>54247571
This is a small minority of Ruby users.

Unfortunately they can still ruin it for everyone else. Gone are the days of linus "fuck you" torwalds; these days you can't be a programmer unless you sign agreements stating you won't hurt the feelings of our precious community of diverse and unique individuals.

but you don't need to "program" to do web dev ;)
you need to "code" aka muddle through using the latest js framework after reading an accompanying tutorial

Or, you know, you could be fired from your job for whispering a dick joke at a python conference, banned from github for posting a comment containing an eggplant icon, have your repo shut down because its title contained the word "retard", get fired from your company because people online found out you once donated to an anti-abortion group, and so on.

Do you already know how to program? If so, the first few chapters of the pickaxe book should be good enough to get started, and after that you can learn by doing actual work. If you don't already know how to program, you can go for "learn ruby the hard way"--it's written by an absolute cancerous faggot but still good for first time programmers.
>>54253571
Also, you'll find SJWs and autists in every programming language. I challenge you to spend some time on freenode's C or Java channels, for example. Ruby's a decent language for some uses that's intuitive enough once you know it that you often won't even need to check the docs, much less the shitty rails community.
>>54238852

>>54245046
Nokogiri always builds it's own XML library from source rather than using the one already installed on your system because the authors of Nokogiri are fuckwits who can't be bothered to make their shitty Gem work with slightly different versions, so instead they just bundles in libxml2 & libxslt and builds it *every time you install or update Nokogiri*
XML is shit, Nokogiri somehow managed to make it even more shit.
>>54255593
