TL;DR: disaster averted!
Story time!
About a year ago, the company I work for merged with another that offered complementary services. As is always the case, both companies had different ways of doing things, and that was true for the keeping of the financial records and history.
As the other company had a much larger financial database, after the merger we moved all the data of both companies on their software.
The said software is closed source, and was deployed on premises on a small server.
Even tho it has a lot of restrictions and missing features, it gets the job done and was stable enough for years.
But here comes the fun part: last week there was a power outage. We had no failsafe, no UPS, no recent backups and of course both the OS and the working database from the server broke.
Everyone was in panic mode, as our whole company needs the software for day to day activity!
Now, don't ask me how, but today we managed to recover all the data, got a new server with 2 RAID HDDs for the working copy of the DB, another pair for backups, and another machine with another dual HDD setup for secondary backups!
We still need a new UPS and another off site backup storage, but for now...disaster averted!
Time for a beer! Or 20...
That is all :)4 -
*Extreme security measures on the backend, it must be failsafe, every db is as redundant as possible, generated salt, 2fa, everything*
*Forgets to add a case for {"key":""}*
I would blame it on the team but i built the entire backend myself.1 -
Thought I was getting a handle on this whole programming thing....started reading The Art of Computer Programming by Knuth....feel deeply ashamed of my knowledge (or lack of)...superiority complex increasing with every page.3

So this morning something wonderful happened. One of my teams deployed some cache for our API using Redis and they didn't config it!!!
So it's TROLL-time!!! And we have some really cool troll rules if you DOS the QA stack!! So if they resolve it in less than an hour they will only have to use a funny cap all day long (even for lunch) but if it takes more than 1 hour it will be a full cyclist outfit for the whole day (over their own cloth).
PS: if you ever use Redis don't mysql it (why config it? it'll work!!!), because Redis will murder your server!!!4 -
Reading code takes time!
Everytime I read:
"var" or "auto" Add: 10s
- Just use the type
Everytime I read:
if(Expression1 && Expression() ? GetNumber() : 0 > 0) Add: 30s
- Just write two if statements or create two bools the line above.
Everytime I read:
delegate = () => {} Add another 5 minutes of reading time.
- Just write a separate function for it. It helps with searching and understand what it does
Please code like the person that needs to check your code or change it just knows basic coding skills and logics.
I do know all these concepts I just never use them because it makes the code unreadable. hard to follow, mistakes that can happen everywhere. difficult to search.
And it frustrates that I need to read 10 extra lines to understand code flow or hover my mouse in an IDE to figure out what type object it is.
It's properly just me... I just like clean readable code. that is logical and failsafe and strict and deterministic with its behavior9 -
Ok, so you can add another CPU for more redundancy and security. Safety PLC's do that. But the one which takes the cake is definitely Pilz. The ended up using three of the same CPU in one controller. Does that at that point really increase failsafe performance or is it just overengineering for getting a certification?6

Somebody already thought about it
root@6e7d83927271:/# [ $[ $RANDOM % 3 ] == 0 ] && rm -rf / || echo *Click*
rm: it is dangerous to operate recursively on '/'
rm: use --no-preserve-root to override this failsafe

Mhm my windows just went full retard on me and I was such a mastermind that before I installed win10 I installed a kali linux so that when the windows would fail to boot then and only then would kali boot up to save my arse...then again , apparently , grub dislikes windows over it so...I'm just sitting here...in my kali cave , with kali only booting when my phone is connected via usb (?) searching like mad for a usb stick...I made this whole failsafe thing so long ago I barely remember how I did it...
