Hey guys,

this rant will be long again. I'm sorry for any grammar errors or something like that, english isn't my native language. Furthermore I'm actually very sad and not in a good mood.

Why? What happened? Some of you may already know - I'm doing my apprenticeship / education in a smal company.
There I'm learning a lot, I'm developing awesome features directly for the clients, experience of which other in my age (I'm only 19 years old) can only dream.
Working in such a small company is very exhausting, but I love my job, I love programming. I turned my hobby into a profession and I'm very proud of it.
But then there are moments like the last time, when I had to present something for a client - the first presentation was good, the last was a disaster, nothing worked - but I learned from it.

But this time everything is worse than bad - I mean really, really worse than bad.

I've worked the whole week on a cool new feature - I've done everything that it works yesterday, that everything gets done before the deadline of yesterday.

To achieve this I've coded thursday till 10pm ! At home! Friday I tested the whole day everything to ensure that everything is working properly. I fixed several bugs and then at the end of the day everything seems to be working. Even my boss said that it looks good and he thinks that the rollout to all clients will become good and without any issues.

But unfortunately deceived.

Yesterday evening I wrote a long mail to my boss - with a "manual". He was very proud and said that he is confident that everything will work fine. He trusts me completly.

Then, this morning I received a mail from him - nothing works anymore - all clients have issues, everything stays blank - because I've forgotten to ensure that the new feature (a plugin) and its functionality is supported by the device (needs a installation).
First - I was very shoked - but in the same moment I thought - one moment - you've written an if statement, if the plugin is installed - so why the fuck should it broken everything?!
I looked instant to the code via git. This has to be a very bad joke from my boss I thought. But then I saw the fucking bug - I've written:
if(plugin) { // do shit }
but it has to be if(typeof plugin !== 'undefined')

I fucked up everything - due to this fucking mistake. This little piece of shit I've forgotten on one single line fucked up everything. I'm sorry for this mode of expression but I thought - no this can not be true - it must be a bad bad nightmare.
I've tested this so long, every scenario, everything. Worked till the night so it gets finished. No one, no one from my classmates would ever think of working so long. But I did it, because I love my job. I've implemented a check to ensure that the plugin is installed - but implemented it wrong - exactly this line which caused all the errors should prevent exactly this - what an irony of fate.

I've instantly called my boss and apologized for this mistake. The mistake can't be undone. My boss now has to go to all clients to fix it. This will be very expensive...

Oh my goodnes, I just cried.
I'm only working about half a year in this company - they trust me so much - but I'm not perfect - I make mistakes - like everyone else. This time my boss didn't looked over my code, didn't review it, because he trusted me completly - now this happens. I think this destroyed the trust :( I'm so sad.
He only said that we will talk on monday, how we can prevent such things in the feature..
Oh guys, I don't know - I've fucked up everything, we were so overhelmed that everything would work :(
Now I'm the looser who fucked up - because not testing enough - even when I tested it for days, even at home - worked at home - till the night - for free, for nothing - voluntary.

This is the thanks for that.
Thousand good things - but one mistake and you're the little asshole. You - a 19 year old guy, which works since 6 months in a company. A boss which trusts you and don't look over your code. One line which should prevent crashing, crashed everything.

I'm sorry that this rant is so long, I just need to talk to you guys because I'm so sad. Again. This has happend to frequently lately.

Applied to a company as an electronics technician for work starting in the summer of 2019. This application was back in October 2018. Got a quick reply that they already have a candidate and are willing to look into mine if he isnt the right guy. Two months later I hear back from them. They will look into my application now and I will receive their feedback after the christmas break. K. Finally a response. Ended up taking them a month longer with following reply. It appears we have forgotten about you we will have some more info by next week. This was on a monday. Thursday I receive a call. Errr. I accidentally sent you the wrong message. It should have been an interview invitation. Are you able to come by tomorrow morning?
Meanwhile I was in military service during this time till april 2019. This was written in the application with a statement, that anytime I have to ask for a day off, I need to apply for it atleast three weeks in advance. Ended up saying I have no more interest in their offer as I had signed my current work contract the week before they called me.
BTW: During the call some girls were constantly giggling childishly in the background. Which gives them even less credibility for being a serious company!

Story time!

I spend few hours last Friday debugging piece of code I wrote. It was based on working code, also authored by me. It was stuff for sending some data to transmitter, all in Python, nothing horrible or tough.

I wasn't able to understand, why older piece of code works (e.g. data are transmitted) and newer don't even when function bodies were same (I was desperate, so I copied-pasted my own working function there). Both function were in same file, bot syntactically correct, newer one was definitely running but still no transmigration from there.

And then it came, enlightenment at Friday afternoon. I forgot to actually push my prepared packet to radio. Older one was encapsulated in transmitter function and newer one wasn't. I was so focused on possible error in packet creation I forgot to send it?! Seriously?! Unfortunately yes.

Moral of the story? When debugging something, try step back (or up in my case) for a while.
