So a friend of Mine asked me to check their Mail server because some emails got lost. Or had a funny signature.

Mails were sent from outlook so ok let's do this.

I go create a dummy account, and send/receive a few emails. All were coming in except one and some had a link appended. The link was randomly generated and was always some kind of referral.

Ok this this let's check the Mail Server.

Nothing.

Let's check the mail header. Nothing.

Face -> wall

Fml I want to cry.

Now I want to search for a pattern and write a script which sends a bunch of mails on my laptop.
Fuck this : no WLAN and no LAN Ports available. Fine let's hotspot the phone and send a few fucking mails.

Guess what? Fucking cockmagic, no funny mails appear!

At that moment I went out and was like chainsmoking 5 cigarettes.

BAM!

It hit me! A feeling like a unicorn vomiting rainbows all over my face.

I go check their firewall. Shit redirected all email ports from within the network to another server.

Yay nobody got credentials because nobody new it existed. Damn boy.

Hook on to the hostmachine power down the vm, start and hack yourself a root account before shit boots. Luckily I just forgot the credentials to a testvm some time ago so I know that shit. Lesson learned: fucking learn from your mistakes, might be useful sometimes!

Ok fucker what in the world are you doing.

Do some terminal magic and see that it listens on the email ports.

Holy cockriders of the galaxy.

Turns out their former it guy made a script which caught all mails from the server and injected all kind of bullshit and then sent them to real Webserver. And the reason why some mails weren't received was said guy was too dumb to implement Unicode and some mails just broke his script.

That fucker even implented an API to pull all those bullshit refs.

I know your name "Matthias" and I know where you live and what you've done... And to fuck you back for that misery I took your accounts and since you used the same fucking password for everything I took your mail, Facebook and steam account too.

Git gut shithead! You better get a lawyer

An open standard quotes the same guy in 2/3 refs, very open indeed.

This guy damaged JavaScript as a language more than anyone else in the world, and he may still call it an achievement.

And this, ladies and gentlemen, is why you need properly tested backups!

TL;DR: user blocked on old gitlab instance cascade deleted all projects the user was set as owner.

So, at my customer, collegue "j" reviews gitlab users and groups, notices an user who left the organisation
"j" : ill block this user
> "j" blocks user
> minutes pass away, working, minding our own business
> a wild team devops leader "k" appears
k: where are all the git projects?
> waitwut?.jpg
> k: yeah all git projects where user was owner of, are deleted
> j.feeling.despair() ; me.feeling.despair();
> checks logs on server, notices it cascade deletes all projects to that user
> lmgt log line
> is a bugreport reported 3(!) years ago
> gitlab hasnt been updated since 3 years
> gitlab system owner is not present, backup contact doesnt know shit about it
> i investigate further, no daily backup cron tasks, no backup has been made whatsoever.
> only 'backups' are on file system level, trying to restore those
> gitlab requires restore of postgres db
> backup does not contain postgres since the backup product does not support that (wtf???)
> fubar.scene
> filesystem restore finished...
> backup product did not back up all files from git tree, like none of refs were stored since the product cannot handle such filenames .. Git repo's completely broken

Fuck my life

In case of emergency:

1. git commit
2. git push
3. Leave building

> Failed to push some refs. To prevent you from losing history, non-fast-forward updates were rejected. Merge remote changes before pushing again.

🤦

Shower thoughts:
If windows 10 is the last version of windows and all new progress will come as feature updates,

i) How will Microsoft release their currently being researched ReFS file system?

Also
ii) does this mean that windows 10 is turing complete OS?

BTW I use arch ;P

Edit: typo

It's hard to teach git to a beginner! There's just so many bits of info that you have to know before it clicks into place. Not to mention git's "reuse" of certain commands with files and refs.

So let's say you spent over a day trying to clone WebKit using git but it failed every single time. Because the WebKit repo is HUGE (at least 7GB of worthless bloated refs), your connection is unstable, and git doesn't resume.

Then you discover you can solve the issue by simply cloning it via SVN in your cmake script.

Then you hit build, and forget that you had `-j 8` set in your IDE settings.

Then your computer freezes when it tries to compile 8 of WebKit's "UnifiedSourceXXX.cpp" files at a time, and all your 16GB of RAM get obliterated.

What the fuck, universe?

Today I spent hours trying to figure out how the hell to add a Material-UI tooltip onto the ClearIndicator for a react-select multi-select component to warn the user that it would clear _all_ of their selections. Followed the examples in the react-select docs on how to make use of replaceable components, but all of their examples used a different library for the tooltip component, and there was no way I was going to bring in _another_ library that was going to add even more dependencies to the application.

In the end, my problem was that all of the examples were with components that could carry a ref and the component _I_ was targeting was a <path> element, which apparently can’t.

Solution? Add a div between the tooltip and the component I was replacing.

*facepalm*

Like seriously how fucked up are those ORMs? Prisma “yeah we support mongodb, but we will force you to write in a relational way.” I always hit on hard walls whenever ever I try an ORM in my projects.

Don’t get me wrong they are good for dummy stuff. But if you want to go a little bit crazy with mongo, embedded documents with refs it’s a mess…

Typescript and good old mongodb adapter bb anything else.

MongoDB database with really relational data. One main collection that had refs to four other collections, all of those references necessary to populate data for a page view. Complicated aggregate to populate all the necessary data and then filter based on criteria selected by the user. And then the client decides that he wants the information to be sortable by column. Some of those columns are fields on the main model, no problem. Others are fields on the refs, which is more of a problem. Especially given that these refs aren’t one single object. They’re arrays of objects.

The revelation was that I could just write an aggregate function to flat map the main collection, returning only the fields necessary for the search, and output it to a new collection and instead use that new collection for displaying and filtering/sorting search results.

But you can’t run the aggregate all the time, you surely say. If anything changes in the main collection, it won’t be reflected in the search results!

Mongoose post(‘findOneAndUpdate’) hooks, my friends. Mongoose post(‘findOneAndUpdate’) hooks.

Never been so happy to have a thing working properly in my life.

OOP is all about code reusability until you really want exactly the code Foo with non-pure functions in all your classes. You end up almost rewriting all subclasses' properties into the superclass to silence typecheckers. Is there no "I know what i'm doing, please just transpile/compile this piece of logic into these 20 places I need?" You end up doing it the functional way, dumping refs and params into some shared util function and have it do the job. I know, might as well have that one inherited also, but what's the point of adding more mess just for that ?
