Oh yeah. I always copy and paste from old files.

IIRC:

rails g migration AddStuffToTableName new_column1:integer new_column2:text #etc. etc.

Helpful protip. I learned yesterday, that list.toArray(new String[0]) is faster than the version with the explicit size given.

Oh yeah that's a big one

I was just like that... but then I've found regex101.com/ and now, I'm almost proficiente writing regex!

It's funny in my case. I know enough regex to get by, but I generally need to google to find out how to actually apply it.

Do I need RegExp.prototype.test or String.prototype.match in JS? What are the order of parameters in preg_match in PHP? What are the little parentheses things called in .NET, captures or groups?

I had the same problem, until I found Rubular:

rubular.com/

Bonus tip: making a permalink will also save all the test cases used. Makes for an excellent inline comment!

Me too!
Hahaaahaa

Same here...
BTW, I knew someone must've been written about regular expressions when I read the title.. 😂

I can never remember how it works either. I found this to be helpful, though! regexr.com/

Same here. I can only remember $,^,*,+ and /s /w. I always end up up googling an example and going from there.

I always have to Google regex. Or copied old code.

I have postgres installed via homebrew. So I use brew info postgres to copy the start command :)

So did I then I realize how many precious minutes of my life I'm losing so I decided to buy a domain for 75 cents mycodesnippets.space :) I write things down little by little as soon as I need it the first time or I risk to never do it by lazyness !

I was gonna say this. Have bookmarked the stackoverflow post on this. :D

cant you just sudo service postgresql start ? :P

I could never remember "rails new myapp --database=postgresql" :|

Oh yes, I even googled and used this today because my service keeps stopping.

at least extracting is easy (say it in a german accent) tar -xzf "xtract ze files"

I figured out how to remember it. To create tar, use c option and for extracting replace c with x ==> $tar will remain same for both Lol :) . tar -cvf filename.tar file/dir_path && tar -xvf filename.tar.

Hey, I also want to make a tar file for my website name:Lenny face. Let me know if the given suggestions works for you!

I just ssh-k ↑ in zsh and just list all previous key generation commands or if I am not sure what I am looking for I use fzf

# fh - repeat history
fh() {
  print -z $( ([ -n "$ZSH_NAME" ] && fc -l 1 || history) | fzf +s --tac | sed 's/ *[0-9]* *//')
}

I was helping someone with this earlier this year. Ended up creating a helper for it:

Best link I've seen all week. Heroic!!!!!

That's awesome! thanks

here's a handy multiple choice questionnaire!

Saw a comment from above and it changed my life.

tar -xzf filename xzf = "Xtract Ze Files!" (german accent)

tar -xf filename

Read as tar eXtract File filename.
Saw this on an SO answer and never had to google it ever again :)

Yeah. For some reason I really find some git procedures harder to memorise than others. It's ludicrous the number of times I've googled "git unadd a file" and "git reset branch to remote"

Oh boy, this gets me every. Single. Time.

I've been using Vim now for about 24 years. Primarily because I don't know how to quit.

The same with me!! But I found VerbalExpressions (github.com/VerbalExpressions) to have solved it for me.

I usually just go to regexr.com and trial-and-error the syntax until it matches what I want.

Regex kills me sometimes.

You could add a function to your .bashrc to make this easier:

listening() {
    lsof -n -iTCP:$1 | grep LISTEN
}

Then (after restarting your terminal or typing source ~/.bashrc) type listening 8080 to find out what process is blocking that port.

I got a good way to remember argument order for ln:
Destination is optional so it must go second.
By default ln creates a link with the name of the source in the current directory.

Oh yeah, linking. Forgot about that one (obviously, since I need to Google it every time lol).

Many moons ago, at one of my first jobs, I got myself in trouble with this. I was editing something in prod without knowing how to save or exit. I was a windows nt guy mostly. So, like one does, I hard-rebooted the server instead of asking for help... After the dust cleared, my boss made me sit at a keyboard for over an hour launching vim and learning how to at least save and exit. :) I have :wq, :q,:q! burned into my muscle memory to this day...

That's unneccessarrelly, but true.

This! Plus a few other words: convenient, conscience, accommodate. I'm not a native speaker ;).

I don't have to Google the spelling, but I'd say 99% of the time I type "valud". I say it correctly as "val-id" and only mistype because of the QWERTY keyboard layout. This is the only word that I consistently type incorrectly. It's not a speed thing (like "teh"), because it happens when typing slowly as well. I've been typing for a really long time and I'm beginning to think my brain just thinks this is a funny prank.

this alone should tell you you need to use another language ;)

Argument orders in all array functions in PHP for me. That's just horrible. VSCode gives hints though, so that helps. I still have to look up the exact names of functions regularly, though.

The best thing they ever added to Slack was the /shrug command.

Ha! Me too. I know to go straight to textfac.es

vim...

Git, brew, and bundler all have some kind of prune flag so it's starting to stick for me.

easy to remember because it is like dried fruit!

I literally added an alias to my ZSH config for this one

alias flushdns='sudo killall -HUP mDNSResponder'

Ever heard of ufw?

What gets me is when I'm switching between languages. Java uses add, Python has append, and Ruby uses push. But then some gem will use add.

This is why I shamelessly use IDEs while everyone I work with uses vim.

This can't be a Set

data = {}

It's always a dictionary!
If you want an empty Set use:

data = set()

P.S. it's handy to use the official Python REPL and type type(youvariable) ;)

ever play:

vim-adventures.com/

?

bonus tip: a lot of unix commands support vim keys by default. i.e. less and man
