What's the best tool you didn't know you were missing, but could not work without it now

So many programming ideas, but so little free time🙁

Today I finally found a randomly appearing bug that prevented our nightly backup on our production servers! Finally!
Now I can go to sleep in peace.

Today I found a huge performance bug of a coworker which brought our production servers to the limit.
Some heavy calculations were made 3 times when visiting some special pages... Instead of eg. 5 seconds the load needed 15 seconds.😮
So happy that the servers will run smooth again!

We are currently refactoring our application in order to use multiple languages. The application startet 1997 and later it supported 2 fix languages. So it's one defined language or the other, this was used in uncountable places. Now a team of 6 developers has to refactor all the code of the last 20 years, where labels are used and an old translator was magically used out of nowhere..
Turns out it's a ton of work to get the software ready for really multiple language support.

/dev/null is like a black hole. You know it exists, but you cannot communicate with it. It has no output, only input. It swallows all data it can possibly get and nobody knows what it looks inside.

I finally published my first open source project. A package for calculation a geohash of a geolocation for pharo smalltalk.
I know that most of the users don't know smalltalk but it's the best OOP you can code with. And geohash is such a great algorithm. Lovely combination

That feeling when you fixing bugs in production and add another one that's even worse, so now your getting about 300 error mails for a bug which was 10 seconds online...

Hey, it seems that you use dotOs, don't you?

Well, is there a full list of supported devices? I am trying to install in S8 or Mi A1, but i dunno if it is actually supported or not, Thanks!

So you're behind a corporate proxy. What can go wrong will go wrong. Believe me.

So, working on real multi language support today I was searching for countries and country-codes. Yes this one is easy peasy. Also easy if you want every countryname in your supported languages.
But why is there no source for the states or provinces translated in every language. It's so hard to find...
Anyone knows a source for it? Is it worth to create a project for such translations?

Went to girlfriends family. Tablet not functional (screen doesn't work anymore), laptop stayed at home.
So smartphone is my only connection to Internet.
I would like to code something so much...
I think I've now read every rant here...

Oh man, why is there no good api for ocr in PDFs? Once you are searching for this kind you will only find some kind of tesseract.
Why doesn't have Amazon an api for this???
