The project where I realized I wanted to go from chemist to pro dev.
I built a flow-chemistry spectrometer with monitoring backend in Haskell.
Spectroscopy is where you add a reagent to a glass tube, it changes color, and by measuring the exact color it tells you how much of something (for example, a toxin) is present in the sample.
I had to do that a lot on factory samples, writing down measurements using pen & paper.
I'm lazy so I decided to do the logical thing: Automate it. I bought a second hand spectrometer, stripped the casing, did a shitload of glassblowing and hooked up tubes to the production pipelines, so I could get samples, mixing them in the correct ratio with reagents in continuous flows using valves.
I ended up using 2 home-crafted arduino-like boards (etching PCBs is fun!).
One to calibrate the mixture against known samples and control solenoid valves to continuously cycle through various reagents and deionized flushing water, the other to record the measurements and send them to a server running a Haskell/Yesod API.
The server collected the information into InfluxDB (A time series database), displaying all data on a graphite dashboard.
Eventually I wrote Haskell plugins for most of the chemistry processes, from pH & temperature measurements to polymer property and pigment tests (they made a lot of printer ink).
Then I was fired because they didn't need chemists anymore, and the code "could be maintained by the intern" (poor guy)...
But I did find out that I loved functional programming, chemistry automation projects, and crafting my own electronics during that time.16 -
To replace humans with robots, because human beings are complete shit at everything they do.
I am a chemist. My alignment is not lawful good. I've produced lots of drugs. Mostly just drugs against illnesses. Mostly.
But whatever my alignment or contribution to the world as a chemist... Human chemists are just fucking terrible at their job. Not for a lack of trying, biological beings just suck at it.
Suiting up for a biosafety level lab costs time. Meatbags fuck up very often, especially when tired. Humans whine when they get acid in their face, or when they have to pour and inhale carcinogenic substances. They also work imprecisely and inaccurately, even after thousands of hours of training and practice.
Weaklings! Robots are superior!
So I replaced my coworkers with expensive flow chemistry setups with probes and solenoid fluid valves. I replaced others with CUDA simulations.
First at a pharma production & research lab, then at a genetics lab, then at an Industrial R&D lab.
Many were even replaced by Raspberry Pi's with two servos and a PH meter attached, and I broke open second hand Fischer Sci spectrophotometers to attach arduinos with WiFi boards.
The issue was that after every little overzealous weekend project, I made myself less necessary as well.
So I jumped into the infinitely deep shitpool called webdev.
App & web development is kind of comfortable, there's always one more thing to do, but there's no pressure where failure leads to fatalities (I think? Wait... do I still care?).
Super chill, if it weren't for the delusion that making people do "frontend" and "fullstack" labor isn't a gross violation of the Geneva Convention.
Quickly recognizing that I actually don't want to be tortured and suffer from nerve damage caused by VueX or have my organs slowly liquefied by the radiation from some insane transpiling centrifuge, I did what any sane person would do.
Get as far away from the potential frontend blast radius as possible, hide in a concrete bunker.
So I became a data engineer / database admin.
That's where I'm quarantining now, safely hiding from humanity behind a desk, employed to write a MySQL migration or two, setting up Redis sorted sets, adding a field to an Elastic index. That takes care of generating cognac and LSD money.
But honestly.... I actually spend most of my time these days contributing to open source repositories, especially writing & maintaining Rust libraries.10 -
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 -
Perhaps not "best", but certainly most amusing, so what the heck!
Years ago as an intern, I applied to a large pharmaceutical company. On part of the application form, you had to enter the code of the department you were applying to.
What I *should have* put down was "IT", which is the department that houses all their devs. However, I didn't actually read any of what the codes meant, assumed that was the department for helping people with how to mail merge, and put down "COMPSCI" instead. This was computational sciences - loosely summarised as computational data analysis on various druggable molecules.
I do *not* have any sort of biology or chemistry background, so the interview was rather... interesting, and I muddled through on the basis of getting some more interview practice assuming it was a no go.
To my amazement, got a phone call saying that they'd been thinking they wanted someone more technical on the team, and despite my lack of scientific experience they thought I'd be a good fit. I was unsure as to whether I should accept for a while, but then decided to just go for it - and had a fantastic internship there, working on a great variety of stuff, and learning tons all under a supervisor who I'm still in touch with to this day.
tl;dr - Applied for the wrong job. Coincidentally got it anyway, and miraculously had a fantastic year working there.8 -
Homework:
Create a fact file and orbital molecule to the substance I've adviced you.
Me:
- 1min ctrl+c ctrl+v of facts/description
- 2h making a 3D model in blender lol
Conclusion:
I like wasting time8 -
Mountain climbing. Increases social skills, teamwork and trust.
Building a house. Increases spatial visualization and planning skills.
Electronics. Increases mathematical and problem solving skills.
Chemistry. Increases precision and analytical reasoning skills.
Psychedelic drugs. Increases imagination, inspiration and abstraction skills.24 -
I was tasked with maintaining a handful of chemistry simulations for the web. First things first, replace these outdated links and turn them into Bootstrap buttons that work on mobile. Wait, why do all of these look so horrible on mobile? nothing's scaling properly. *looks at fucking 1,000-line CSS file* The old developers used position:absolute for absolutely EVERYTHING. And I counted one div on the entire page. This is why you don't trust chem engineers to do your "web design" #FuckDreamweaver7

Ugh, fxk. I got a promotion, I'm now a team lead for 4 developers, and I fxking hate it.
They never asked me if I wanted the position, they just threw me into it this week. They ripped me away from the team I had great chemistry with and put me on this other team with people I have no connection with.
To make matters worse, I'm also responsible for production servers of the clients of this team, one has malware even.
On top of all of this, they made me move desks for a new developer to fill my spot.
How do you demote yourself? Why would a company want someone to perform poorly (on purpose, I don't care) than to just keep their employee happy?

Today at school:
We had a chemistry lesson. Somehow we came to talk about Linux...
So first our teacher said that Linux is shit.
Then another student said, Linux would be like Windows.
Teacher searched for "linux ist scheiße" (which means "linux is shit") on YouTube and let us watch a video.
He also said the whole Internet says Linux is shit and that it would never be more important then Windows.
Kill me pls😢13 -
Holy shit. I'm sitting in my CS class and I just heard someone complaining about the stupid responses they get when they tell people they're a CS major.
I heard a new one that is honestly the most stupid fucking thing ever. She told someone she's a CS major and they replied "Oh so are you taking a lot of chemistry classes or something?"4 -
Why do so many people waste their time and their computers turning coal into heat? It really pisses me off.
Often I meet smart guys who are fairly decent coders and after what starts as an interesting conversation is instantly destroyed by cryptocurrency.
It is *exactly* like enjoying a discussion of the intriguing nuances of quantum chemistry only to have the guy say, "thats all cool, but how do you make meth?"
argh.
You want to use your decked out rig to make money? Fine. But please help us solve important problems instead of literally wasting electricity. Just google search "supercomputer physics" and you will find a thousand current problems requiring extremely fast computers for number crunching. All of them can make you more money than crypto and all of them help society at the same time.
We burn coal to make most of the electricity on this planet. Most coal stations burn around 20,000 tons of coal per day. The world burns about 250 tons of coal every *second*. This is converted into carbon dioxide. (coal = carbon, add two oxygens when you burn it, producing three times as much mass in CO2, which then goes out the smoke stack)
The big picture is this: currently we are forced to burn coal to make the world work. Turning off the boilers would result in an almost instant apocalyptic collapse of society. BUT, we don't need to burn it merely to produce waste heat in your video card array.
Please use your superpowers for good.

While exploring matterverse.ai, I looked at the formula for rubber:
C5H8.
its bandgap is 5.803
After a few minutes I discovered a slight modification:
C2H4, with a bandgap of 6.85!
"Holyshit, why aren't linemen using this instead of rubber for electrical insulation?"
*looks up formula*.
C2H4, the formula for:
Ethylene.
It's ethylene, a highly flammable gas.
And now you know why I don't do chemistry.8 -
So, 27 hours. 27 hours I've been awake at this point.
I was actually planning on sleeping last night, but I was talking to my ex for a while (until around 2 am). Beat Portal again. Decided to get a thing or two done real quick. By the time I got that shit done, it was like 5, and I have to be up at like 6:45, so I felt like sleeping wasn't worth it anymore. Had a fairly good day at school, managed to stay awake (even through AP chemistry!), kinda started talking to a girl.
I'm fucking tired guys.16 -
Fuck this system. Fuck college. Why the fuck are you making me write hundreds of chemistry assignments and calculating double integrals? How the fuck does that even help me? I seriously feel like college sucks up a huge chunk of my time and I am not learning anything, while I practice Node and Vue at home. Why does that degree hold so much value when most degree holders don't even have skills?30
-
My college forces you to take chemistry, physics, mechanics, philosophy, and Environmental science before you even take your first coding course. WHYYYYYYYYYYYYYYYYY......... I didn't apply for this XD7

Why do I need to study Chemistry when I chose B.Tech in Computer Science and Engineering.
Oh! Thanks to the great Indian Education system.16 -
I forged a katana once, under the supervision of a swordsmith. Nothing super special like damascus patterning or anything, but the cutting edge was pretty sharp.
Ugh sorry, lame word jokes.
In terms of software...
Microsoft Office Ribbon (cutting edge at the time, lol). Only as a maintenance drone on a bunch of manual search-and-replace work and merge conflict resolving.
Ariane 6 family of rockets (Welding X-rays and other DICOM quality assurance).
Software for continuous flow chemistry, developing microfluidic PCBs to perform Elisa immunology assays during the Mexican flu outbreak. Idea was to eliminate the need for microplates, expensive robots, microwell washers, etc — just have blood plasma, enzymecoated nanoparticles, antigen, conjugated detection reagents and substrates flowing programmatically through a PCB with a spectrophotometer built in.5 -
Someone (QCat) on devRant offered me to be his contact, it ended up with him teaching me a HUGE lot of stuff, enabling me to now code an operating system alongside him (o and I learned maths, formalism, biology, chemistry, game dev, REAL C++, drawing [I still suck at all of them though] )
So yea, thats it from my side2 -
!(dev || rant)
Dudes and dudettes, i shall ask you all one question: what is the thing/hobby (or things/hobbies) that you always wanted to get into and never gor the chance?
For me i thing first would be brewing, as i would love to refer to myself as a "Brewmaster" like in Warcraft (bonus points if i wear a panda costume) more then an "Engineer" (a trust worthy one even), but i think i might have the chance to as soon as i will have the chance (and means) to move alone as i already know a few things from my dad. The second would be something really cool i saw on reddut and made me remember the old times when i will watch timelapses in this topic on you tube: Crystal growing! Like, middle school chemistry, not meth! At least for now.. 🤔 Anyway, here is a nice pic with some dude's work, looking forward to hear abiut yours!!
PS: Bonus Points for a pic related to the thingie!8 -
I could not do anything else. Physics, Chemistry, Biology didn't interest me.
Tried competitve programming, failed miserably.
Tried app dev and server dev, they surprise me with their awesomeness everyday :D1 -
There are not enough words in the English language to describe how much I fucking hate general education courses and math.
I don't even want a CS degree anymore just to escape the hell that is called required general education courses.
Like why do I need two fucking lab based science classes? Sure, if you were doing the Computer Science with a focus in Chemistry, that makes sense. But I wasn't doing that.
Why do I even need a lab science of CS to begin with, let alone two.14 -
!devButAlsoKindaIsDev
Alright, time to do some explanation.
TL;DR: JavaScript is a fucking nightmare. May god help every web developer out there. Essentially, I was gone because of JavaScript.
Q: where tf are you bruh
A: in your mo-uhhhhh alright, so I was chosen to be the main developer for an interactive promotional video for my school (every year the school holds something called an open day, where kids from 8th grade can come to the school and have a tour in the school first hand. Because of the coronavirus (just gonna call it “the rona” from here) this is now impossible so we are losing the interest and the first impressions so the school decided to make an interactive virtual one). They asked me if I want to do it and I said yes.
Boy, was that ever a mistake... (hint: it was a huge mistake)
So the guy who talked to me and asked if I wanted to do this was my grade’s manager, and he gave me the phone number of my PM. So we talked and stuff, and then this happened: (bruh = PM)
bruh: I’ll send you the API and documentation for the thing that we are working with! They have lots of examples and stuff and they’re Israeli too!
Me: Okay! What language are we talking about here?
bruh: JavaScript.
Me: (questioning life choices) Okay!
I didn’t write any JavaScript for the last 3 years or so. It had to be done because I promised and I can’t let down people who count at me and ask me to show where I shine.
So, what was the objective for me? Build a Firebase client that sends the user’s score and choices to Firestore after he chooses something in the interactive video (for example, go to chemistry or go to physics) while learning JavaScmeme (ECMEMEScript) as I go.
Deadline? A week and a half.
After working almost 12 hours a fucking day, I made it work. Sorta. In order to reconcile with small exceptions and edge cases in the interactive video, I had to hard-code some IDs in the code. I had no choice, since I couldn’t allow myself to spend more and more time to make my code more dynamic than it was because I simply didn’t have time. The code absolutely STINKS but it works.
Today is the day where we (aim) to finish all of the cosmetic things that we need to fix. All of them are non-essential for everything to work, but we want to make this thing presentable because we want to put this on the school’s website.
CONCLUSION:
JavaScript is literal shit. Dynamic weakly-typed languages are cursed AF and need to die in a fire.7 -
Managed to land 2 interviews:
The first one was for a startup that was looking for a react programmer (I've never used react before).
The later was a php job at a big company. They told me they used cakephp which is a framework I had not used before either.
Still, I'm more familiar with php than react so I felt more confident with the second interview. However, I felt there was a lot of good chemistry going on in the first interview.
The interviewer was incredibly nice (he was the lead dev, not an HR person as opposed to the second interviewer)
He gave me a small react test to be completed within a week. I barely managed to do it in time but I felt good about the solution.
Just as I was sending it, I get a call from the second interviewer saying I landed the php job.
I wasn't sure if my novice react skills would be impressive enough to secure me the react job (and I really needed a job) so I accepted.
After explaining everything to the guy who was interviewing me for the react job, he understood and was kind enough to schedule a code review where he walked through my novice code explaining what could be improved, helping me learn more in the process.
I regret not accepting the react position. The PHP they got me working with is fucking PHP5 with Cake2 :/
Don't get me wrong, I like the salary and the people are nice but the tech stack they're using (lacking source control by the way!), as well as all the lengthy meetings are soul-draining.6 -
Unemployment..
Learned tons about physics, chemical bindings, chemistry, and so on..
Even stuff like math behind music.
Having some time off is really valuable..3 -
Ladies and gentlemen, Introducing Rezn0v-Jr, this guy was born(created) yesterday on an underperforming device later shifted to my primary device. And is not complete machine learning type. He is Pythonborn (eh.. not Dragonborn). For now he can't understand human response but only can speak (print) few sentences.
PS- Chemistry exam on Tuesday
Update- I dropped my phone again right after post finished uploading.1 -
You know when you just spend about three full days learning for the upcoming chemistry exam?
Well I certainly do.
AND THEN THE FUC*ER PUTS SH*T IN THE EXAM THAT HE DID NOT EVER FUC*ING TEACH US.5 -
"damn bro, you made that? how can i get into coding?"
shut the fuck up. you can get into programming like anyone who wants to can. by googling how to code. it's not the question itself that bothers me, it's the fact that if you actually wanted to code so bad, you already would've googled it. stop projecting your lack of passion on me.
this is most common with programming, but it happens so often with so many other things.
if you want to learn about biology and chemistry, there's free courses online and papers from nih.
if you want to learn about forsenics read a book about it and read about cases and how they were solved.
i could go on and on. the internet gives you access to so much that if you actually wanted to learn something, you would've already have.4 -
Fuck my country's universities, fucking greedy assholes that ruin lives, suck wallets and sucks life from the young.
I'm currently studying something completely non related to programming: History. And I really love it. I love reading 1000 pages for each test and essay and talking about the problem of naming the Cold War a war and cold and etc. The problem is that I won't make as much money as I would make even as a self taught developer.
After considering my possibilities, I thought I could enter the computer science carreer. I don't know how this works in other countries but here you would have to study 3 years of an engineering common plan and then specialise in some sort of industrial engineering while getting an specialisation also in computer science. After some counting, I got to the conclusion that I would be studying 6 years (or more), and wasting half of those years learning stuff that I would never use nor care about.
But that's not all. This semester I took the introductory class for programming. It's pretty basic stuff but at least they teach a little bit about algorithms and problem solving. It turns out that a friend of mine that's about to graduate from computer science applied as a helper for the prof. I was so excited I could finally talk with someone about code!
Since the start of the semester I have been passing a lot of time with him and talking about the future. Turns out he doesn't understand shit about code but somehow he learns everything by hard and has passed every computer science course without having any practical abilities. I don't blame him, he's studying hard and playing by the rules, and turns out that he has wasted precious time of his life also learning biology, chemistry, structural engineering, hidraulic engineering, transportation engineering and a ton of engineerings that he won't use.
If the university would instead take that time to teach better courses of practical programming or leave him some time to try out the stuff he learns by hard, he wouldn't have to hear me talking about stuff he doesn't comprehend but feels that should, and wouldn't be utterly depressed, he wouldn't take SIX years to learn less than what he could learn in less than THREE years. And this isn't just a random university, it is one of the 2 best universities we have here and was in 2014 the best of all Latin America.
And wait, here comes the best part. In my country, levels of education are heavily stratified. After school, superior studies give different titles according to the time you've been studying. Yes just the time. And these titles are what your employers will see to give you different work positions. So for studying a 2 year carreer you get a technic job which pays well but not too well, then at 4 years you get a license title which only proves that you know stuff, then at 5 or more (depending on what you are studying) you get a professional degree and will get payed as a full fledged professional. So here, even though in other countries it takes 6 years to have a masters in engineering, they give you just the engineering degree, and it would take 2 (or more) more years to have a master. Even though you can totally teach engineering in 4 years, here they take BY LAW 2 years more, while paying what a fucking full stack of pairs of kidneys would cost in the black market.
So fuck that shit, I won't be throwing my money at any university. I hope they get reformed soon becouse this is fucking dumb, really really dumb. Like 2 year old shit dumb. I'll just learn a bit more, make some projects until I have a decent portfolio and apply to some company that cares for real knowledge and not just a piece of paper with letters and a shitty logo on it.undefined student job revolución fuck university shitty universities student life education im just a bit pissed11 -
When I became a dev my parents said: "it's not rocket science, or chemistry or anything good, but at least it's not stressful, or dangerous and we can get free tech support. I hope you are able to pay your own bills and find rent"
A few years, a degree and finding a supportive woman who is now my wife and and I make 4 time as much as my parents make now they want me to move back so they can get their tech support and see my wife I guess she is more social than I am -
There's nothing wrong with asking algorithm and data structure questions in an interview if the employer calls for it.
If you're hiring a junior and/or you desperately need workers, then you can lower the bar, but if you want to be picky, then asking them leetcode-tier coding questions is fine.
THERE'S NOTHING WRONG WITH ASKING A SOFTWARE ENGINEER CANDIDATE DATA STRUCTURES AND ALGORITHM QUESTIONS
If they complain that asking ds&a questions is unfair for a position where all they're going to do is shit-tier frontend work, then blacklist them for 10 years.
If people argue that Doctors don't get asked chemistry and biology questions for interviews, tell them it's because medicine is much more regulated than software and that doctors are vetted technically even before they're allowed to go job hunting. Since software doesn't have the same regulations medicine does, employers have to do the technical vetting themselves.
If you think it's unfair to ask software engineering questions to a candidate applying for a software engineering job, then find a different career.9 -
Sometimes just I hate school.
While my gf had to take 2 "Leistungskurse" ("advanced courses"), I have to take 3.
Also, our little-country-side school doesn't offer IT-class as a Leistungskurs. So besides Math, I need 2 extra courses I am super-not interested in. I chose English since it's okay (but I'm not really good either) and ( ._.) chemistry. I had a good teacher in 10th grade but now I have this teacher who
- uses 1980 material
- explains not/bad most times
- is childish as fuck (we are 17-18 y/o)
- expects too much (we need to learn everything by heart)
- throws ugly, unorganized prints at us w/o context & explaination
and I could name more. My A-levels are going to be so fucking bad. Tuesday is my chemistry exam. Kill me, please......4 -
I don't consider myself a guru in JavaScript (hell I studied theoretical chemistry), but I do hate much of the rationalization behind building a Jenga stack of libraries, frameworks, dependencies... for building everything web related.
Many of the problems I see people solving with these giant stacks could be easily solved understanding how websites work (html, css, js and how interact with each other) with no dependencies giving smaller (for end users at least) and more maintainable code (in the sense it would not require updating dependencies that may be discontinued...)
I do imagine situations where these are ideal... Since there are not absolutes and developing is very context sensitive, but man if I have js article fatigue for ridiculous scenarios.2 -
Found this book amongst other 7 grade school books...
Fuck, kids are learning the basis for every technical job this days, in my time even chemistry was only theory... Let alone practical lessons5 -
The University Struggle: when you want to actually code and learn your major but you have an English essay, a Spanish project, chemistry homework, and a book to read all within two days.

Not to mention my actual computer science classes don't teach anything useful in terms of programming6 -
I see. They have to be geeky...mmmmh
I read a lot about biology, chemistry, physics and mathematics.
My two fav subjects are biology and math from the above. And I try to attend to as many lectures as I can.
Biology fascinates me to no end and it helps that one of my closest friends works as a resesrcher in Mexico, we are far but we get to talk about it all the time. He is more than happy to go on large lectures about the subject.
I also read a fuckload of fantasy books as well as manga. I also go on anime binged here and there.
In perspective though, i don't think anything is as nerdy as software development. SPECIALLY if it involves large portions of math(which in my case does for the things we develop for the accounting department)

I am from a third world country. Although I went to one of the better schools in my neighborhood, the education didnt work out very well for me (maybe because I wasn't the brightest kid in class). Nothing made much sense except math, but didnt do very well at that either since the number of equations I had to memorize increased every year and I hated memorizing. One day programming started to make sense and from then I got the best scores in the class for programming, somewhat decent scores in math and languages and barely made it for other subjects.
I just continued doing the only thing I was good at. I am really curious about physics, chemistry, biology and other subjects and I religiously watch youtube videos and read articles explaining related concepts. Maybe I would have followed a different career path if my science teachers made any sense. Or maybe I am too dumb for that.
Is programming for me? I am still not sure but I know this is something I like.2 -
heres something interesting:
The golden ratio is 1.618...
If you're not familiar with it, doing 1/goldenratio
the result is 0.618...
It gives you back the float component exactly.
Discovered that it is actually part of a series.
First of all:
2-(((5-sqrt(5))/2)-1) =
1.618033988749895 -> thats our golden ratio
In other words:
(2%gold) =
0.381966011250106
While:
((5-sqrt(5))/2) =
1.381966011250105
Ok, now we're getting somewhere. We can turn these into variables
First of all, lets see if we can get the golden ratio back out:
2-(((5-sqrt(5))/2)-1) = 1.618033988749895
Okay good.
The formula looks something like
j-(((i-sqrt(i))/2)-1)
Where j = (i*2)+1
That means we can easily figure out what j we need from our i value. (i-1)/2 = j
We run it back far enough we get
1-(((3-sqrt(3))/2)-1) =
1.3660254037844386
Thats the golden ratios little brother. Doesn't look anything like it, but it is part of the series.
And I found a boat load of research documents scattered *all* over the net, where this number and others in the series inexplicably crop up in power series, in chemistry, and elsewhere. Just looks like random floats if you don't know better.
We can actually go lower in the series:
0.5-(((2-sqrt(2))/2)-1)
1.2071067811865475
At the lowest positive value for j, we get
0-(((1-sqrt(1))/2)-1) = 1
It's kinda elegant.
I even wrote a little script to do the conversions:
def gr(k):
....i = k
....j = (i-1)/2
....return j-(((i-sqrt(abs(i)))/2)-1)
The dots are so devrant doesn't break pythons formatting.3 -

Why does college have to have so many core classes? I'm a Computer Science major, I don't want to learn about the history of the economy or chemistry, I just want to code! About to finish my first semester of my second year and I've only taken 3 computer-related courses, and about 15 useless cores that add nothing to my education9

Fuck this shit!!
Doing my homework for chemistry and fucking Libreoffice didn't save my work!! And I put a lot of work into it!! Fuck!!
Now I've created a git repository to save my homework and keep track of it.. Fucking Libreoffice... :/
Fuck you!!!! Fucking Libreoffice!!!3 -
Aaaaarggghhh
Having to think about what and when to eat is such a fucking pain in the ass. I don't want to search for recipes. I don't want to think about nutrition. I don't want to count calories. I just want something to tell me exactly what to eat, when I should eat and what to buy. Same goes for workout routines. Just tell me what to do I'll do it. I want an autopilot for that sort of stuff so I don't have to ducking think about it anymore. It's such a giant waste of time to have to manually plan this shit through, I want to use my brain for other things like math or chemistry or Programming. In fact I don't even want to cook because I am alone and cooking for one person is so ducking pointless. I lost over 40kg in the last years. I learned my lesson, most things taste like shit now because I associate food with all the pain and depression that I had to overcome to achieve a normal weight and fit body. Food went from being a joy to being an annoying necessity. I got fit and I want to work out even more but I really don't want to think about this shit. The exercises and pain and hunger are all nothing but planning is my true enemy. It bores me to death, it's more painful than running until I break down I absolutely fucking hate it.
I am really close to start some kind of open source food planner where you can type in your goals ( weight loss, muscle gain etc.) In great detail with all kind of options ( vegetarian, vegan, allergies, budget, country where you live in for local recipes etc.) And it generates a food plan for you with exact details of where exactly to buy the ingredients how to cook them etc. No fancy Ui No bullshit ads for some kind of wonder drug nothing annoying. Something so easy that it can be used as an autopilot for ones fitness and life. Do what it says and you'll look decent, don't think about the rest. Having that would be so great and I could finally think about more important shit than this. Less overhead more time for things that can't be automated.
And Yes I know that this is exactly what a personal trainer would do, but I am not going to spend 600€ a month for someone to tell me exactly what to buy, what to eat and how to work out.23 -
You know what really rustles my jimmies, the fact that a lot of people (especially older people) disregard your profession or refuse to talk about because "i dont understand dem computers" so they generally have no idea what you're actually doing and you cannot give an explanation.
Ffs, I don't really understand chemistry but I would still like to know what you do at work/school and maybe even learn sonething. There is no fucking reason for why this also shouldnt apply for IT.5 -
they say i was a natural at programming. i like it, i understand problems easily and im able to find a solution for it. but so was math, and chemistry. basically anything that has problem solving so i wasn't into programming that much.
until i joined my first competition. man that was an eye opener. we had a deadlock tie with the other team, and there was this one problem that was a tie breaker. sure enough we both was able to solve it. but the judges ruled in our favor because of one thing, i used recursion! man that was fun. the looks on their faces.
and i was hooked on that euphoric feeling. that was my drug. now , a decade or so later, im still addicted to that drug -
Half of the courses in my Bachelor of Engineering in IT course was about electronics. They even had chemistry and drafting.
What did they think I'll get a job in? Making silicon chips or writing CAD software?
And they didn't put in Algorithms. And combined Java and web development into one course.

heres a new constant found this morning
>>> (1.39094974939078**(pi-0.5))-1.39094974939078
==
0.9999999999999867
the following..
>>> 1.39094974939078**2
1.934741205330274 +/- 1
and
((1.39094974939078**(pi-0)))
2.8198510518716056 +0/+1/+1
show up in things as varied as the density of galaxies, gasoline chemistry, traffic accident formulas, and more.
Kinda cool.31 -
!rant. Story:
There are a lot of things I would like to do, but the lack of enough money makes it hard.
My goals are to become more active on YouTube, find clients and hold them, try to learn how to sell products convincingly, become better at web design, understand university-level mathematics, leave Germany (one particular reason for this is the need of the redundant imprint), help people around the world, become more fit bodywise (by doing e.g. swimming, jogging and going to the gym), eat healthy and drink a lot of water, work on my emotional intelligence, learn peoples' behaviours and why they do what they do, write my own book, finally start practicing yoga and muay thai, live on my own, make a world tour for a year, learn the skill of powered paragliding, getting the license for powered paragliding, glide with a powered paraglider the whole day, build a house in the woods, create my own satellite and launch it, develop new things (like building some sort of vehicle that can fly in a special way), learn about biology, chemistry, physics (I hate it, but I believe in the power of what is going to happen once you learn it), become more aware of what is happening, live on the streets with no money to learn the ability to survive in more extreme situations, learn how to use guns, bombs, snipers and knifes properly (don't assume that I am a terrorist now haha, I am just interested in that type of stuff. That's all to it) ...
But all of that, obviously, not in 2020. More like within 10 years.1 -
Is there anyone out there that has experience with reactor network solvers in C++ I could ask some stuff? I hope I'm "Dev" enough to be here, even if I'm a chemical engineering student and not a "classical" developer :)6

DREAM 1
(my comments look like this)
A kikiland metro system. It's extradimensional and shapeshifting. When you enter it, it adapts to your needs. The people inside (they're probably just vinyl shells), the social circumstances, all generated for you.
When you enter it, it knows where you want to go. It spawns exactly one train just for you. It will be the first, it will be the last. You have to catch it to go where you need. If you miss it, there will be no more trains, and you have to wait till the metro station closes for the night and reopens.
It's always you entering, catching the train that arrives just in time, going to where you need to go and exiting.
Because of its extradimensional nature, you cannot agree to meet someone there — every person has their own personal metro generated just for them every time, with exactly one train going exactly to the station you need.
It's used by BLA as a form of control. When they don't want you to go somewhere, the train won't spawn. Or, it might diverge and get you to some other place. It isn't known whether the map can be altered on the fly or not. So far, the consensus is that the map is persistent and is a public knowledge, and it's just the metro itself that is extradimensional. But, no one ever saw the real metro in its real form, and not the top layer that protrudes into the three-dimensional world you can interact with. It might be the case that they can make people disappear by creating ad-hoc stations that don't intersect with the real world, trapping them in places that are nowhere in particular.
(it took seeing BLA once in one dream to make all the following dreams include them. Sigh.)
Kikiland also has a school, and it always had it. I befriended a chemistry teacher there. His classroom is small — exactly as deep as other classrooms, but really narrow. There are no desks there, just his desk and some bookshelves. Chemistry isn't a priority there — his class exists only because it should. No one attends it. This is why he was so pleased to meet me. Despite his classroom being located on a busy floor, its door is overlooked by students, and NO ONE ever enters it. He just sits there, waiting for students to arrive, but they never do.
He has a secret, though, because of course he does. In the game Control, if you complete the main storyline before you complete some side quests, one of the main characters will be sitting in the C-suit hall, doing her things, waiting for you to come and talk to her. But at the same time, she will be waiting for you deep down the oldest house's mines, again, just sitting there, waiting for you to take the quest. This teacher is the same.
If you have a good relationship with him, and you attend his class, the classroom will change to a tunnel entrance, with him being the security guard. He's your friend, he'll let you in. It looks like Fallout's vault entrance. THIS is how you enter the REAL kikiland metro. (Dream 1 ends here.)
Episode 2
Tiny waterborne rat puppies whose mouth is their entire face unfolding like a piece of paper with teeth covering it as a grid. (I wrote about them already, but here they are again.) They are _tiny_, a bit like tadpoles. Also, like tadpoles, they die if you touch them out of water. As I was flying over some mountain resort (I routinely fly in my dreams, but it feels more like a very low gravity falling I can control, like using a parachute in GTA San Andreas), I dumped them to a location that resembled the garden level of Prince of Persia: Warrior Within for my cat to eat. It didn't want to. -

How do smart (and, I presume, well-educated) people get an idea like "Oh, I know what this world needs, another video where someone scientifically disproves a story from the Bible" or "I should commemorate the new year by telling everyone how insignificant this day is for the universe"? How does someone spend years traveling the world, giving speeches about science, teaching curious people about physics, history, mathematics, chemistry, the space, etc., and then figure that the next thing they should share from their impressive knowledge is an edgy video disproving some old story or tradition?24 -
Half of the courses we had in our college were about electronics. Except Microprocessors and Transistors, it's not relevant.
We even had chemistry and engineering drawing. So we essentially wasted more than half of our time.
Besides languages, weren't taught anything about real world software development.
Nothing about how to work with an existing code base, version control, design patterns, system design, creating a website, debugging, functional programming, scalability, reliability.
The industry should be involved in setting the syllabus and also contributing part time teachers.3 -
A-level results lads out tomorrow, got an A, B, B & C in Geography, Maths, Chemistry and Physics, think it'll be good enough for a CS degree at Edinburgh or Queens?6

I'm fucking Paralyzed and I need some advice.
I want to be an entrepreneur.
Not just an entrepreneur but a DAMN good one.
I self-studied business, economics, physics, self-taught multivariable calculus, teaching myself chemistry too.
But I haven't even started my career and I just graduated from University.
Right now I'm starting simple and just doing a few web development things.
But, I want to go deeper into a subject that hasn't really had its problem solved yet.
A.I. can sell you neat things, but it can't kill misinformation (yet).
Graphics are an integral part to gaming, but GPUs are the second greatest threat to our environment behind commercial jets.
Do I HAVE to choose between A.I. and graphics?!14 -
Ok. What the flying ligardshit?! Write down the most ridiculous sentences you had been given when you were dismissed.
Today mine was:
They: Nothing got developed till deadline.
Me: *surprised* Okay maybe I overlooked something, please point out what wasn't
They: This and that project was due tomorrow.
Me: *blankly & calmly* You mean the projects that has been deployed on last friday and wednesday?!
They: *still with pokerface* Okay that is not the real reason. The real reason is we get this type of behaviour from you a lot.
Me: *dead seriously* You mean I have to tolerate your false accusations and bow my head with gratitude?!
They: *angryly* See that is what we are talking about, we don't feal like we have chemistry?
Chemistry?! 'The fuck are you talking about??? Come on!! What the goose shit you think we are some high school teenagers in their first month of relationship?! "Family" my ass!
Okay I know it is much easier to dismiss somebody without having to pay the end-of-year premium but come on, don't assume I am a braindead idiot like you!!!
Things ahead:
- Callback the recent contacted companies
- Update LinkedIn
- Find another job
- Find a way to blacklist companies preveting anybody else falling for cimpanies like this one
- If none create one
- If found / Upon creating put them on
If you happen to be able to help me with one/some/all of the above, let me know2 -
I have a great chemistry with this coworker.
He lacks some depth of android knowledge but is always very interested in adding new google libs to the project, so we often discuss and come up with the safest, scalable solutions.
He is SE2 and I am SE1.
But one thing that is interesting about him is the way he gives estimations for the tasks. He takes usually that much amount of time that i would take, for a task, but he would quote half the time estimates.
the bosses usually come on the last days to check the feature demo, but QAs gets the first build when a task is completed. I have seen his first builds that goes to QA and most of the time, boy it has some amazingly stupid bugs.
dude would just put a util function, then run the build, if everything compiled, he would just give the build to QA directly. he wouldn't even check that the util function gave an expected output or not.
He is simply wasting QA time n efforts, and risking product quality by not testing enough, but he almost always gets a clean chit for this behavior just because he did the work super fast.
Dude is super cool and i don't envy him for his good luck, but rather think of him as an inferior dev. However bosses think of him as a better dev and my TL even once told me to "be like him"
So i guess this is how corporate works. I will try to apply this in my next role in current/next organisation.3 -
- I love blowing my mind. Even if it is the most confusing thing. Things like security mechanisms, neurons' behaviors, mathematics (even tho I hate it when I fail lol), electronics, medical terminology and chemistry.
- I love collecting rare coins, personally never-seen stones and put them into my collection. I love to be a designer. Not only on my laptop. I have a book shelf and within that book shelf I put stones that create the yin yang sign while pushing the books to two sides. That makes them look like they are levitating. I have stones (including obsidian) that create a triangle and a knife hanging down the wall of my room.
- I love visiting touristic, historic, naturally-beautiful but also non-touristic (non-touristic? yes. by that I mean visiting e.g. the areas of touristic cities which are dangerous, because you can easily fall down off of a slippery ground and take serious injuries) places around the globe, talk to complete strangers in public (I am trying to be an extrovert), take pictures with my camera and collecting antiquities.
- I love taking risks (no. I don't play any poker games etc on the internet) without trying to put other people in risk. Driving insanely with whatever I have. Car, bike, you name it.
- I love reading books. Books that are about human psychology, fantasy novels and books about programming languages.
- I love to cook (I am at the beginning).
- I love to use the konMari method of tidying up my room.
- I love plants.
- I love having everything in my room tidied up (even if I am too busy with other stuff and skip this cleaning process for a week upto a month sometimes. Sorry, room.).
- I love doing sports. But mostly sport that I have never tried before. This can be, because of my greedy wish for an adrenaline kick. That led me into taking a balloon flight at 4 am (sunrise) and to paragliding at sunset above Mediterranean sea btw. (I am normally afraid of flying, but paragliding was awesome).
- I love swimming. Like, you cannot pull me out of the sea for a minimum of 2 hours, if it is not important.
- I love laying above the sea water and let the sea carry me to somewhere else.
- I love being alone. I love the silence. I love to be free in my thoughts.
- I love watching the sunset, the light that shines through the forest, the moonlight and the stars at night.
- I love dreaming. No, like, lucid dreaming for example.
- I love being open to any opinions.
- I love to learn about other people's views about the world and their religion.
- I love pets and would do anything to keep them alive when they are ill. It hurts my heart seeing them like this.
- I love watching demonic "A: Holy shit! Did you see this thing, too?! B: Yes!" YouTube videos just for the fun of it, but I hate horror movies and games.
- I love trying out new things. The creation of music and video for example.
- I love to give my hair and beard a shape, if I am too lazy to go to the barbershop lol. By that I don't mean just going to the barbershop, but taking an electric razor and cutting my hair myself even if I get bad results from time to time that can be corrected by letting any family member tell me in which area of of my head the hair problem is.
- I don't like disco clubs.
- I don't like toxic people even though I can be a quite toxic person myself without realizing it. If I appear toxic to you, inform me about it. Having so much testosterone in that moment, can make me do things that I don't want to do.
- I don't like drugs even tho I have to admit that I am trying a few from time to time (maybe 6 months in-between) to have a dopamine kick. I am not an addict.
- I hate myself for things that I did in the past.
- I used to watch MMA videos etc.
- I used to use a telescope, but I can't find it anymore.
- I used to have a microscope, but I can't find it anywhere and besides of that the seller did literally piss in it before selling it to me many years ago. Don't want to touch it tbh.
- I used to play games, but I don't enjoy games anymore. That makes me feel sad.
- I miss the old moments of my life.
In conclusion:
I like how things went and go so far. It changed me so much. It made me a good and a bad person. I became more open and confident, but it also particularly made me a leader who can say "fuck off" in a bad way to his family. I would like to undo this particular part of me.5 -

My time management skills are abysmal. I am in my senior year in school and a few months back decided to appear for the informatics Olympiad. So now I am reading a book on discrete math, while reading books on algorithms and data structures. I code every day for around two hours. I have my math syllabi in school which is all calculus. My physics syllabi consists of all of EM and Optics along with nuclear physics. I haven’t touched chemistry since the beginning of this year. I try to give a considerable amount of time to math and physics because I f***ing love studying those. But doing that means slacking off on the Olympiad stuff. I am completely overwhelmed. My midterms are two weeks away and I am so unprepared. I am really clueless on how to manage time. -
I attempted on national competition in an IT field, where there were tens of great projects (in other fields as well, like chemistry and so..). We had to push everything to their portal, so they can study it in advance. While pushing the docs, I found that there were SQL injections that allowed me to list everyone's rating and to download every single doc / additional sources.
Worst part is, that even after I reported vulnerability, they obviously didn't had time to fix it. -
Warning - Not IT related.
Long ago, I had a chemist professor who told us a story. She worked in a laboratory where they have studied cristal formations, so basically made a liquid highly capable to form cristals, and they watched them forming, doing tests and so on. In the meantime new building of the campus opened and they had to move the lab to the new location, which was a fourth floor of newly made building. Few of them started to work there even before they moved the old materials and equipment and they started few cristalisation studies, the interesting part is that the cristals didn't formed. She said that at the end they had many cups with prepared liquid and apsolutely no cristals for weeks, but one day the lead researcher arrived with the old, already formed cristals, from the old lab, and toon those inside of the room with prepared cups all the cristals started to form at the same time. After telling us a story she asked us not to tell this to anyone because the science currently doesn't accept this phenomenon and we will be demonised and looked fools it the scientific community.
This story made a hole in my brain...
It was like 10 years ago, and as a problem solver I still have sometimes some weird ideas about it, and strange explanations comming from nothing, and without any deep understanding of quantum physics or even cristalisation. :D1 -
So tomorrow I'm gonna tackle my last exam for my MSc presenting the "group project" aka I did it myself (tfw ur mates can't even matlab at least) thingie and sustain the most brutal oral examination in the whole 5 years on organic industrial chemistry.
Wish me luck. -
So we watch some videos when we are learning Chemistry for the first the in school and the videos is like 1 frame per second. Of course we are learning online through Zoom so it maybe is just because of the screen or the internet.
