Regex. While I understand how it works and how it can be used, it's difficult for me to memorize the right regex that should be used at every point. So I just google whenever I want to make use of it. :)

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?
Every once in a while my postgres server isn't running and I know to punch that into my browser and land on this Stack Overflow question, where I proceed to copy this command into my terminal:
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 am a student who loves to contribute and develop in projects.Currently trying to create something that can give purpose to a huge community of developers. I hav no idea what it would turn out to be
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.
Started learning to program seriously early 2017. Love fixing problems so decided to switch careers from e-commerce and management to programming and web dev. Longterm goal is full stack developer.
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"
I would be responsible for 95% of hits coming from google search into the Tutorialpoint's html5 minimal template. Now I could easily type it in every time I set up a new page, but it is now a matter of extreme laziness I think.
How to find out which process is listening on a certain point on my mac. I'm often switching between projects, and have a server from another project running on a port that I now need for another server.
And it looks like Heroku's CLI doesn't always stop all processes correctly when you stop it using ctrl+c
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.
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...
Professional developer for twenty years. Team lead, technical lead.
What I love is to code stuff. I appreciate pair programming. I think software design is important. I also love to debug code.
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.

Find a file in Linux. I know it involves "find" and "name" but I have to look up the exact syntax each time. (For reference, the sledgehammer version is find . -name testfile.txt from the root of the drive.)
Enthusiastic IT generalist. Spent most of my time doing everything with computers since a very young age. If it can be done with a computer, I've probably done it.
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.
Updating the list of git remote branches. It doesn't refresh when you sync so it will continue to list remote branches that don't even exist anymore until you manually run the command below. (Which I had to google again to put in this comment.)

Objective-C block syntax
bash test format and flags
vim macro create and execute
I noticed I could never remember these, so I always make aliases, shell functions, or short ~/bin/ scripts for them instead:
tar: xkcd.com/1168/
netstat flags (other than "-tulpn" which I have memorized as "tull-pin" like "Tolkien")
ssh tunnel syntax

Helpful protip. I learned yesterday, that
list.toArray(new String[0])
is faster than the version with the explicit size given.I was about to write the same thing. How to vertically align elements... without using flex 😂
Regex. While I understand how it works and how it can be used, it's difficult for me to memorize the right regex that should be used at every point. So I just google whenever I want to make use of it. :)
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!
regex101 is the single best resource I've ever found for 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
orString.prototype.match
in JS? What are the order of parameters inpreg_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!
Same here...
BTW, I knew someone must've been written about regular expressions when I read the title.. 😂
Me too!
Hahaaahaa
I always have to Google regex. Or copied old code.
I can never remember how it works either. I found this to be helpful, though! regexr.com/
Same here. I can only remember $,,*,+ and /s /w. I always end up up googling an example and going from there.
For me it's "manually start postgresql"
Every once in a while my postgres server isn't running and I know to punch that into my browser and land on this Stack Overflow question, where I proceed to copy this command into my terminal:
It happens infrequently enough that I never bother to alias it or remember how to type it out. I just remember what to Google.
I have postgres installed via homebrew. So I use
brew info postgres
to copy the start command :)So did I then I realize how many precious minutes of my life I'm losing so I decided to buy a domain for 75 cents mycodesnippets.space :) I write things down little by little as soon as I need it the first time or I risk to never do it by lazyness !
I was gonna say this. Have bookmarked the stackoverflow post on this. :D
cant you just sudo service postgresql start ? :P
On Linux, yes. On OSX, no unfortunately.
I could never remember "rails new myapp --database=postgresql" :|
Oh yes, I even googled and used this today because my service keeps stopping.
How to make a tar file...
at least extracting is easy (say it in a german accent) tar -xzf "xtract ze files"
and -czf == 'compress ze files'
well what works for me is tar -xzvf "xtract ze vucking files"
No kidding that's how remember it
this...is actually brilliant! lol
That's a great way! Jajajaaj
But it's important to note that tar is smart enough to detect the format so I prefer the general
tar -vxf
Even though as a German with decent English pronunciation this is a little bit insulting, I'll probably never forget this ever again. Thanks! 🙈
Thank you so much.
Isn't that for zipped tar files? -xzf = extract zipped (tar) file.
I threw this one at a dev I used to work with. He answered instantly, he could have disarmed 2 bombs with that speed.
Instant respect gained
I figured out how to remember it. To create tar, use
c
option and for extracting replacec
withx
==>$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!

Suprised tldr didn't got mentioned.
It's a pretty neat tool to do this kind of things...
That's awesome! thanks
Best link I've seen all week. Heroic!!!!!
Javascript array methods. Is this one in-place, or returning a new array? I don't know, but MDN does!
How to extract
tar.gz
file in Linux command line!Saw a comment from above and it changed my life.
tar -xzf filename
xzf = "Xtract Ze Files!" (german accent)Excellent, noté that you may get ride of the dash.
tar -xf filename
Read as
tar eXtract File filename
.Saw this on an SO answer and never had to google it ever again :)
Wow, I never thought of it.
Thanks :)
And centering things. Completely clueless every time.

Everything git related
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"
How to delete a remote branch in git.
Cherry picking commits in git, because I can never remember if it's cherrypick or cherry-pick
A more efficient way would be to just do it and correct if it errors, or alias it to git cherry or something
Also, how to exit vim, and how to insert in vim, and basically how on Earth did I end up in vim omg get me out
I've been using Vim now for about 24 years. Primarily because I don't know how to quit.
How to "unignore" files with git... Here is a nice and short way.
I would be responsible for 95% of hits coming from google search into the Tutorialpoint's html5 minimal template. Now I could easily type it in every time I set up a new page, but it is now a matter of extreme laziness I think.
This is stupid but g++ compiling filename and output order in the terminal. I've been doing it for four years now and still failing to remember.
regex
The same with me!! But I found VerbalExpressions (github.com/VerbalExpressions) to have solved it for me.
That is very good to know about.
I usually just go to regexr.com and trial-and-error the syntax until it matches what I want.
Regex kills me sometimes.
How to find out which process is listening on a certain point on my mac. I'm often switching between projects, and have a server from another project running on a port that I now need for another server.
And it looks like Heroku's CLI doesn't always stop all processes correctly when you stop it using ctrl+c
You could add a function to your .bashrc to make this easier:
Then (after restarting your terminal or typing
source ~/.bashrc
) typelistening 8080
to find out what process is blocking that port.ln -s [source] [destination]
orln -s [destination] [source]
?find . -name [...] -exec grep '...' {} \;
And of course sed, awk and more generally shell syntax (if, loops, switch, etc).
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).

Oh god why did they have the new guy making changes in prod you poor soul
How to spell maintenance.
That's unneccessarrelly, but true.
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.

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

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