Long rant ahead, but it's worth it.

I used to work with a professor (let's call him Dr. X) and developed a backend + acted as sysadmin for our team's research project. Two semesters ago, they wanted to revamp the front end + do some data visualization, so a girl (let's call her W) joined the team and did all that. We wanted to merge the two sites and host on azure, but due to issues and impeding conferences that require our data to be online, we kept postponing. I graduate this semester and haven't worked with the team for a while, so they have a new guy in charge of the azure server (let's call him H), and yesterday my professor sends me (let's call me M), H and W an email telling us to coordinate to have the merge up on azure in 2-3 days, max. The following convo was what I had with H:

M: Hi, if you just give me access to azure I'll be able to set everything up myself, also I'll need a db set up, and just send me the connection string.
H: Hi, we won't have dbs because that is extra costs involved since we don't have dynamic content. Also I can't give you access, instead push everything on git and set up the site on a test azure server and I will take it from there.
M: There is proprietary data on the site...
H: Oh really? I don't know what's on it.
<and yet he knows we have no dynamic data>
M: Fine, I'll load the data some other way, but I have access to all the data anyway, just talk to Dr. X and you'll see you can give me access. Delete my access after if you want.
H: No, just do what I said: git then upload to test azure account.

Fine, he's a complete tool, but I like Dr. X, so I message W and tell her we have to merge, she tells me that it's not that easy to set it up on github as she's using wordpress. She sends me instructions on what to do, and, lo and behold, there's a db in her solution. Ok, I go back to talking to H:

M: W is using a db. Talk to her so we can figure out whether we need a database or not.
H: We can't use a database because we want to decrease costs.
M: Yes I know that, so talk to her because that probably means she has to re-do some stuff, which might take some time. Also there might be dynamic content in what she's doing.
H: This is your project, you talk to her.
<I'm starting to get mad right now>
M: I don't know what they had her do apart from how it interfaces with what I've done.
H: We still can't have databases.
M: Listen, I don't do wordpress, and I'm not gonna mess with it, you talk to her
H: I won't do any development
<So you won't do any dev, but you won't give me access to do it either?>
M: Man, the bottleneck isn't the merging right now, it's the fact that W needs a db
H: I know, so talk to her
M: THE RESTRICTION TO NOT HAVE DATABASES IS NOT MINE, IT'S YOURS, YOU TALK TO HER. I can't evaluate whether it's a reasonable enough reason or not since I don't know the requirements or what they're willing to spend.
H: It's your project.
M: Then give me fucking access to azure and I'll handle it, you know you'll have to set up wordpress again regardless whether we set it up the first time.
H: Man just do your job.

At this point I lost it. WHAT A FUCKING TOOL. He doesn't wanna do dev work, wants me to go through the trouble of setting up on a test subscription first, and doesn't want to give me access to azure. What's more, he did shit all and doesn't want to anything else. Well fuck you. I googled him, to see if he's anyone important, if he's done anything notable which is why he's being so God damn condescending. MY INTERNSHIP ALONE ECLIPSES HIS ENTIRE CV. Then what the fuck?

There's also this that happened sometime during our talk:

M: You'll have to take to Dr. Y so he'll change the DNS to point to the azure subscription instead of my server.
H: Yea don't worry, too early for that.
M: DNS propagation takes 24 hours...
H: Yea don't worry.

DNS propagation allows the entire web to know that your website is hosted on a different server so it can change where it's pointing to. We have to do this in 2-3 days. Why do work in parallel? Nah let's wait.

I went over his head and talked to the professor directly, and despite wanting to tell him that he was both drunk and high the day he hired that guy, I kept it professional. He hasn't replied yet, but this fucker's pompous attitude is just too much for me alone, so I had to share.

PS: I named his contact as Annoying Prick 4 minutes into our chat. Gonna rename him cz that seems tooooooo soft a name right now.

Seriously, god bless Laravel and Taylor Otwell.

I've just had a customer foolishly delete all their user accounts. The customer was seriously stressed about this and as it usually goes, this stress was echoed in the call.

I explained how they can easily restore the deleted records in a single click as I have configured Laravel's "soft delete" functionality site wide. i.e. when they delete a record it isn't really deleted. Functionality to physically delete the record is hidden away outside the client's user level.

Customer was seriously grateful and paid for 2 hours of my time (even though the call took 15 mins) and generally gave me lots of kudos.

Laravel, awesome.

When i delete a facebook post. Deep down i know...

I swear I didn’t hit delete and then confirm delete... Then why do we have 3 different software analytics that show all the mouse clicks leading up to and including the mouse click of you deleting the customer... thank goodness I set up soft deletes instead of hard deletes like the legacy system use to be.

Soooo MY BOSS has proved himself stupid and ignorant.

And asshole.
So he changed the db because he decided after 4months building everything around a db we changed aaaand OF COURSE NO ORM as I already told you.

So raw queries fine. What queries? Well, he decided we dont need delete.

We had a soft delete before where archived was true but the entity still in db.
Fine we dont need delete?!? Ok sure

Today, him:" guys is it ok if I add some stuff to db?"

Me:"Well, taking into account we dont have delete that data will be with a lot of garbage and irrelevant data"

Him:" yes we dont need delete, in the future we will need archived true"

Me:" that's what the old delete was doing"

HE DOESNT KNOW THE FUCKING APP.
He IS VP ENGINEER
COO AND PM THINKS HE KNOWS STUFF WHEN HE DOES NOOOOOOT

FUCK THAT COMPANY.

(tldr: are foriegn keys good/bad? Can you give a simple example of a situation where foriegn keys were the only and/or best solution?)

i have been recently trying to make some apps and their databases , so i decided to give a deeper look to sql and its queries.

I am a little confused and wanted to know more about foreign keys , joins and this particular db designing technique i use.

Can anyone explain me about them in a simpler way?
Firstly i wanted to show you this not much unheard tecnique of making relations that i find very useful( i guess its called toxi technique) :
In this , we use an extra table for joining 2 tables . For eg, if we have a table of questions and we have a table of tags then we should also have a table of relation called relation which will be mapping the the tags with questions through their primary IDs this way we can search all the questions by using tag name and we can also show multiple tags for a question just like stackoverflow does.

Now am not sure which could be a possibile situation when i need a foriegn key. In this particular example, both questions and tags are joined via what i say as "soft link" and this makes it very scalable and both easy to add both questions and new tags.

From what i learned about foriegn keys, it marks a mandatory one directional relation between 2 tables (or as i say "hard a to b" link)
Firstly i don't understand how i could use foriegn key to map multiple tags with a question. Does that mean it will always going to make a 1to1 relationship between 2 tables( i have yet to understand what 11 1mant or many many relations arr, not sure if my terminology is correct)

Secondly it poses super difficulty and differences in logics for adding either a tag or question, don't you think?
Like one table (say question) is having a foreign key of tags ID then the the questions table is completely independent of tag entries.

Its insertion/updation/deletion/creation of entries doesn't affect the tags table. but for tag table we cannot modify a particular tag or delete a tag without making without causing harm to its associated question entries.
if we have to delete a particular tag then we have to delete all its associated questions with that this means this is rather a bad thing to use for making tables isn't it?

I m just so confused regarding foriegn keys , joins and this toxi approach. Maybe my example of stack overflow tag/questions is wrong wrt to foreign key. But then i would like to know an example where it is useful
