To become an engineer (CS/IT) in India, you have to study:
1. 3 papers in Physics (2 mechanics, 1 optics)
2. 1 paper in Chemistry
3. 2 papers in English (1 grammar, 1 professional communication). Sometimes 3 papers will be there.
4. 6 papers in Mathematics (sequences, series, linear algebra, complex numbers and related stuff, vectors and 3D geometry, differential calculus, integral calculus, maxima/minima, differential equations, descrete mathematics)
5. 1 paper in Economics
6. 1 paper in Business Management
7. 1 paper in Engineering Drawing (drawing random nuts and bolts, locus of point etc)
8. 1 paper in Electronics
9. 1 paper in Mechanical Workshop (sheet metal, wooden work, moulding, metal casting, fitting, lathe machine, milling machine, various drills)
And when you jump in real life scenario, you encounter source/revision/version control, profilers, build server, automated build toolchains, scripts, refactoring, debugging, optimizations etc. As a matter of fact none of these are touched in the course.
Sure, they teach you a large set of algorithms, but they don't tell you when to prefer insertion sort over quick sort, quick sort over merge sort etc. They teach you Las Vegas and Monte Carlo algorithms, but they don't tell you that the randomizer in question should pass Die Hard test (and then you wonder why algorithm is not working as expected). They teach compiler theory, but you cannot write a simple parser after passing the course. They taught you multicore architecture and multicore programming, but you don't know how to detect and fix a race condition. You passed entire engineering course with flying colors, and yet you don't know ABC of debugging (I wish you encounter some notorious heisenbug really soon). They taught 2-3 programming languages, and yet you cannot explain simple variable declaration.
And then, they say that you should have knowledge of multiple fields. Oh well! you don't have any damn idea about your major, and now you are talking about knowledge in multiple fields?
What is the point of such education?
PS: I am tired of interviewing shitty candidates with flying colours in their marksheets. Go kids, learn some real stuff first, and then talk some random bullshit.18 -
WHAT THE FUCK.
I have to deal with a fucking bug that crashes my app only when I'm NOT looking for it.
I investigate another bug? Then BAM, here it is and crashes the app. And I have to start over again find the right conditions to not trigger it again.
I investigate that bug? Nope, everything runs as smooth as velvet.
It's like a Heisenbug, but the cat is dead in the box AND pissing all over the lab at the same time.3 -
Yeah. Kinda late to the WK 227 party.
Thing is: I've read a lot of rants and honestly, some of the rants were ... touchy.
Like that weird emotional thingy you don't like but that just kind of happens cause I'm human too.... And have that shitty emotional feature integrated, which feels most of the time like a heisenbug.
Me and my parents. Specifically mom. Are like ... Matter and antimatter.
You don't want them in a room. Bad things happen TM. My mom is responsible for ... Let's say severe psychological trauma starting with age 4 to age 17.
In 17 I moved out and lived on "my own" (truth: on heavy support, cause I wasn't what you'd called "psychologically stable" at that time).
I fucked up university and - as shared before - thanks to an math teacher who made my life an even more living hell and my parents, I'd started in IT mostly out of "resisting" certain assertations being made over my life.
The support I got from my family can be put together in one sentence:
"I survived, I tolerated - but will never forgive".
Thing is: Be it IT support or anything else. If your gut feeling tells you that family / coworkers / friends are not good for you.
Stay the fuck away from them till you've sorted yourself out.
I can tolerate my parents nowadays. Took > 10 years and a lot of hardships to "achieve" that.
It's not peachy. It's not loving. It's tolerance. (Yeah. That bit is muey importante to me).
The thing is: I cannot deny the fact that my parents tried to support me by money. That's what they still do _nowadays_ even though my income is like 60 % of the income my father and mother has combined... It's a bothersome detail.
There's a certain thing in this rant that I would like "to pass on": Emotional support matters.
When you let someone feel like an empty shell, you cannot fix it with money.
It will - severely - destroy the person.
TLDR: We all have rough edges, can be hard to deal with and be a pain in the arse, but all of us need emotional support sometimes. That's what matters the most. ;)1 -
Y'all ever heard of a heisenbug? I've run into them a few times, but never knew they had their own term! XD

Figured out a heisenbug in the app that my coworker (a rockstar 10X dev who I look upto to) couldn't pinpoint at. And then we both sat together and fixed it :)
-
I once had to write a feature, which should allow the user to login and edit an appointment, which was automatically set. All the data we got, came from an incredibly unreliable API. And with incredible unreliable I mean like heisenbug-level unreliable.
The API spoke perfectly unreadable xml and was a horror to work with.
After a few weeks of me being messed with by this shit piece of an API, I finally got something which did kind of work sometimes.
Proper error handling has been added later and just before I was done, fixing all the flaws of their data management and nonsense status codes (not http status codes) which rarely correlated in at least some way with their data, our client said "scrap this, we don't want it anymore"
Many hours and effort gone, this thing worked almost perfectly. -
How on earth is there any "sane" software (eco-)system or will it always be so crazy because as pieter hintjens might have said all this soft- and hardware is created by this social animal called human, with all it's faults and aberrations...
So it was just, that I could not print - probably because of this bug: https://bugs.debian.org/cgi-bin/... - couldn't install a newer ghostscript. So I would scp my files inside an Ubuntu-VM from which I could print. Sometimes I could pdf2ps some files or transfer back the ps-file and print on my host machine, but mostly not... U n t i l today when I installed the fucking debug symbols package for ghostscript and I could just fucking print. Heisenbug, ghost error or what?1 -
I declared it a Heisenbug!
So, basically I was starting multiple threads...
I was getting a list index out of range on line 268 which was a dict. Strange.
36 hours later, a lot of changes, I was still having the same error whatever I put on line 268, log, try, but when I got it on a comment... I lost it.
Restarted Pycharm.
Reset the branch to remote.
Everything worked fine.
Fuuuuuuuuuuu
