Biggest challenge I overcame as dev? One of many.

Avoiding a life sentence when the 'powers that be' targeted one of my libraries for the root cause of system performance issues and I didn't correct that accusation with a flame thrower.

What the accusation? What I named the library. Yep. The *name* was causing every single problem in the system.

Panorama (very, very expensive APM system at the time) identified my library in it's analysis, the calls to/from SQLServer was the bottleneck

We had one of Panorama's engineers on-site and he asked what (not the actual name) MyLibrary was and (I'll preface I did not know or involved in any of the so-called 'research') a crack team of developers+managers researched the system thoroughly and found MyLibrary was used in just about every project. I wrote the .Net 1.1 MyLibrary as a mini-ORM to simplify the execution of database code (stored procs, etc) and gracefully handle+log database exceptions (auto-logged details such as the target db, stored procedure name, parameter values, etc, everything you'd need to troubleshoot database errors). This was before Dapper and the other fancy tools used by kids these days.

By the time the news got to me, there was a team cobbled together who's only focus was to remove any/every trace of MyLibrary from the code base. Using Waterfall, they calculated it would take at least a year to remove+replace MyLibrary with the equivalent ADO.Net plumbing.

In a department wide meeting:

DeptMgr: "This day forward, no one is to use MyLibrary to access the database! It's slow, unprofessionally named, and the root cause of all the database issues."
Me: "What about MyLibrary is slow? It's excecuting standard the ADO.Net code. Only extra bit of code is the exception handling to capture the details when the exception is logged."
DeptMgr: "We've spent the last 6 weeks with the Panorama engineer and he's identified MyLibrary as the cause. Company has spent over $100,000 on this software and we have to make fact based decisions. Look at this slide ... "
<DeptMgr shows a histogram of the stacktrace, showing MyLibrary as the slowest>
Me: "You do realize that the execution time is the database call itself, not the code. In that example, the invoice call, it's the stored procedure that taking 5 seconds, not MyLibrary."
<at this point, DeptMgr is getting red-face mad>
AreaMgr: "Yes...yes...but if we stopped using MyLibrary, removing the unnecessary layers, will make the code run faster."
<typical headknodd-ers knod their heads in agreement>
Dev01: "The loading of MyLibrary takes CPU cycles away from code that supports our customers. Every CPU cycle counts."
<headknod-ding continues>
Me: "I'm really confused. Maybe I'm looking at the data wrong. On the slide where you highlighted all the bottlenecks, the histogram shows the latency is the database, I mean...it's right there, in red. Am I looking at it wrong?"
<this was meeting with 20+ other devs, mgrs, a VP, the Panorama engineer>
DeptMgr: "Yes you are! I know MyLibrary is your baby. You need to check your ego at the door and face the facts. Your MyLibrary is a failed experiment and needs to be exterminated from this system!"

Fast forward 9 months, maybe 50% of the projects updated, come across the documentation left from the Panorama. Even after the removal of MyLibrary, there was zero increases in performance. The engineer recommended DBAs start optimizing their indexes and other N+1 problems discovered. I decide to ask the developer who lead the re-write.

Me: "I see that removing MyLibrary did nothing to improve performance."
Dev: "Yes, DeptMgr was pissed. He was ready to throw the Panorama engineer out a window when he said the problems were in the database all along. Didn't you say that?"
Me: "Um, so is this re-write project dead?"
Dev: "No. Removing MyLibrary introduced all kinds of bugs. All the boilerplate ADO.Net code caused a lot of unhandled exceptions, then we had to go back and write exception handling code."
Me: "What a failure. What dipshit would think writing more code leads to less bugs?"
Dev: "I know, I know. We're so far behind schedule. We had to come up with something. I ended up writing a library to make replacing MyLibrary easier. I called it KnightRider. Like the TV show. Everyone is excited to speed up their code with KnightRider. Same method names, same exception handling. All we have to do is replace MyLibrary with KnightRider and we're done."
Me: "Won't the bottlenecks then point to KnightRider?"
Dev: "Meh, not my problem. Panorama meets primarily with the DBAs and the networking team now. I doubt we ever use Panorama to look at our C# code."

Needless to say, I was (still) pissed that they had used MyLibrary as dirty word and a scapegoat for months when they *knew* where the problems were. Pissed enough for a flamethrower? Maybe.

Waking up from a dream with a girl in it.
TL;DR: We fell in love and I can finally somehow remember her. Not completely though...

(To the perverts: We did not have sex nor did we kiss.)
The worlds I am becoming a part of are very complex. I won't get into the details of how they look like. I will tell as far as I can remember.

<vaguely remember the beginning>
My sister, my mom and I went into a house which turned out to have weird things inside.
Suddenly I became something like an agent and I had a special mission. I went to the basement of this building. Saw a few guys chilling there. Grabed a walkie talkie which was taped on the right wall. I have listened to it while moving back to the entrance, when I have arrived there, it began to do disortion type of sounds.

<I have been to a lot of different places here. Telling each of them would make me to not come to an end lol>

Then I have decided to go outside. The outside-of-the-house world changed. I was at floor 8 or something like that. It was very high when I looked down. All of the sudden I got into a waterfall type of thing which was about to suck me in to a circle. The waterfall was limited to the area of where this house was. It was basically hovering above the streets, but never reaching the streets.

I somehow met the lovely girl in a cube type of thing that helped us not to fall down through the spiral. We enjoyed the action the waterfall created. It made us move in a circle and we had to hold ourselves at the wall of the cube which luckily had knobs to hold on.

After that whole action I have been in my bed and sleeping. She somehow found me on a social media platform and contacted me with "Meet me on <some strange date>".

<some unlogical world shit happens here. I will just skip them until the date>

The day to meet her comes. She is up on a hill with a "purple?<idk it was purple-ish>" sky.

<can not remember the dialogue>

We had a great time and I felt that she had feelings for me.
She then went away. What about me? And me, too. ;)

The next day I went to see her again. She was gone. I found out that she has a brother. I talked to him about where she might be. Turns out her brother was a demon or satan <idk they all became agressive and god-like powerful lol>.
He told me that she must be there where <random name of enemy> is to fight the enemy to rescue her mom.

Her brother went to help her. I followed him since I did not know where the enemy was. Let alone where I was. The world has changed for the 99999th fucking time lol.

I followed him up another hill with trees and a lot of people. It was autumn.

Then we found her sitting on a hill looking down to the sea beneath us with cherry blossom trees around her.

The dream was about to end. I felt it. So I have asked her a few questions after the happy greeting, but I can not remember them and her answer anymore. But I do remember that she did not say anything after one question. She just stared at me looking through my eyes which immediately did end the dream.
I was able to get into the dream shortly after it a few times, but I was not able to interact with them.

Besides of that: I have had "Battle Symphony-Linkin Park" playing as a background music for the whole dream a long.

The good thing is that I somehow would be able to recreate her. I know how she looks like to about 60%.

I do not even know why the fuck I am telling y'all this.

So I've been hired as a senior software developer with all the tags included (mentoring, innovating, pushing forward changes) for a company that is trying to move away from waterfall development (yup, it's 2019 and this exists) to a more iterative workflow.
I was initially hired and sent out to do some "field work" abroad for 3 months and then worked "remotely" from the local office with our field partners.
During all this time it seemed that my ideas go through smoothly, there was a lot of chatter about how things are moving forward, how new projects, innovations and new methodologies are implemented.
And yet, after my "remote" work has finished and I have to do things locally more, all of the skeletons fell out. It's just talk, nothing seems to be changing at all and yet any attempts to talk with the brass is like hitting a brick wall.
Not only that, I've been handed a 12 year old project with no possibility to refactor, no technical documentation, very few comments and in a terrible style.
The atmosphere in the company is odd as hell. People are either not very initiative, nor they seem to really care about all of the "changes" that "should be happening".
It almost feels that I've arrived in a company that still lives in 2007 more or less.
Should I quit, or perhaps it's a little "too soon" (have spent 7 months in the place already)? What I don't want is to get in the same train again (work for a company for 8 - 12 months, feel burned out because of the divergence between actual things done and "plans" and then change the job).

The best part about being a developer, is building something cool, and other developers telling you how cool it is (and suggesting improvements)
