Smart India Hackathon: Horrible experience
Background:- Our task was to do load forecasting for a given area. Hourly energy consumption data for past 5 years was given to us.

One government official asks the following questions:-
1. Why are you using deep learning for the project? Why are you not doing data analysis?
2. Which neural network "algorithm" you are using? He wanted to ask which model we are using, but he didn't have a single clue about Neural Networks.

3. Why are you using libraries? Why not your own code?

Here comes the biggest one,

4. Why haven't you developed your own "algorithm" (again, he meant model)? All you have done is used sone library. Where is "novelty" in your project?

I just want to say that if you don't know anything about ML/AI, then don't comment anything about it. And worst thing was, he was not ready to accept the fact that for capturing temporal dependencies where underlying probability distribution ia unknown, deep learning performs much better than traditional data analysis techniques.
After hearing his first question, second one was not a surprise for us. We were expecting something like that. For a few moments, we were speechless. Then one of us started by showing neural network architecture. But after some time, he rudely repeated the same question, "where is the algorithm". We told him every fucking thing used in the project, ranging from RMSprop optimizer to Backpropagation through time algorithm to mean squared loss error function.

Then very calmly, he asked third question, why are you using libraries? That moron wanted us to write a whole fucking optimized library. We were speechless at this question. Finally, one of us told him the "obvious" answer. We were completely demotivated. But it didnt end here. The real question was waiting. At the end, after listening to all of us, he dropped the final bomb, WHY HAVE YOU USED A NEURAL NETWORK "ALGORITHM" WHICH HAS ALREADY BEEN IMPLEMENTED? WHY DIDN'T YOU MAKE YOU OWN "ALGORITHM"? We again stated the obvious answer that it takes atleast an year or two of continuous hardwork to develop a state of art algorithm, that too when gou build it on top of some existing "algorithm". After listening to this, he left. His final response was "Try to make a new "algorithm"".

Needless to say, we were completely demotivated after this evaluation. We all had worked too hard for this. And we had ability to explain each and every part of the project intuitively and mathematically, but he was not even ready to listen.
Now, all of us are sitting aimlessly, waiting for Hackathon to end.😢😢😢😢😢

I JUST FINISHED MY FIRST NEURAL NETWORK!!!

But first of all, as I know you guys, it's spaghetti code and even I as a newb see places where I used too few-dimensional array or passed useless parameters or simply wrote too many redundant lines of code. I know it. I will make it MUCH better next time. Period.

But OMFG this made me scream from happiness today!! Just these few seemingly random numbers... I'm really done.. That's why I jumped into coding year or two ago..

And for some background, I didn't study any IT school, I'm just highschooler (general grammar school) who traded gaming for learning. Also my maths teacher teached NNs on university and is very keen to teach me, so that's that.

Now I wanna make the best out of it and I'm looking forward to write some well documented and flexible library, parallelized and everything (I'm gonna learn a lot in the process of doing this) better then FANN.

Maybe I'm gonna fail(99% probability but hey, I'm programmer beginner, I still think I can code everything I want). But if there is just one moment like when I saw this screen today, I'mma trade my life for it.

Sorry for taking your time guys, I was just genuinely stunned... A lot

"No matter how slick the demo is in rehearsal, when you do it in front of a live audience, the probability of a flawless presentation is inversely proportional to the number of people watching, raised to the power of the amount of money involved." - Mark Gibbs

I got a friend who likes to travel randomly to random places.. he now found some dudes who share this hobby.

So now there is a thing running on my server ticking everyday, 10am, with a 1:150 probability to send a sms to 7 numbers (including me) which tells them to travel to budapest.

FYI: he and his friends study engineering, i study too. So 1:150 may sound pretty low at first but we don't have that much time over the year actually.:D

Russian Roulette Travelling is a thing now.😁

Client:
"Ok,. so your saying that its gonna take you 63 hrs to create a simplified CRM with basic functionality and auto fill docs or automated work flow docs as an added feature?"

My response (after already under-quoting and planning on cutting some corners because he has a smaller budget than normally necessary):
"It sounds simpler than it is. There are a lot of things I need to take into account that you wouldn't even think about.

For instance:

Making sure your emails don't go to the client's spam folder. This requires the sending domain to be verified via DNS settings. I have to ensure your email content passes a spam test (link to text ratio needs to be good). I assumed you'd want an email that has your logo and looks good. This means testing the design in Outlook to make sure it's not broken.

What if the email doesn't send due to an invalid email address, or bounces back? You'll need to be notified.

What if the client list for the week contains duplicates? You need them merged or ignored.

Generating a PDF from HTML can be tricky because the conversion isn't apples to apples so there are things I need to adjust to make them as close as possible.

Making a site completely mobile friendly (the tier 3 option) can be very time consuming as well. It's not about whether or not it fits on a mobile phone, it's about whether or not it's intuitive and useful. You're essentially getting a mobile app without paying for separate development of an app.

If I took everything into consideration and built this to be 100% bullet proof, it would cost tens of thousands.

I'm doing my best to leverage your needs with the probability of running into an issue. I'm not going waste my time/your money on something that will likely never happen."

My manager (who is a PhD) says that the difference between probability and percentage is that the former ranges from 0 to 1 and the latter ranges from 0 to 100.

Now the only question I have is, "Where can I buy PhD?"

(Warning: kinda long && somewhat of a political rant)

Every time I tell someone I work with AI, the first thing to come out of their mouth is "oh but AI is going to take over the world!"

No.

It was only somewhat recently that it started being able to recognize what was in a picture from over 3 million images, and that too it's not that great at. Honestly people always say "AI is just if-else" ironically, but it isn't really that far from the truth, we just multiply an input by weights and check the output.

It isn't some magical sauce, it's not being born and then exploring a problem, it's just glorified-probability prediction. Even in "unsupervised" learning, the domain set is provided; in "reinforcement learning" which has gotten super popular lately we just have the computer decide which policy is optimal and apply that to an environment. It's a glorified decision tree (and technically tree models like XGBoost outperform neural networks and deep learning on a large number of problems) and it isn't going to "decide" to take over the planet.

Honestly all of this is just born out of Elon Musk fans who take his word as truth and have been led to believe that AI is going to take over the world. There are a billion reasons why it can't! And to top it off this takes away a lot of public attention from VERY concerning ethical issues with AI.

Am I the only one who saw Google Duplex being unveiled and immediately thought "fraud"? Forget phone scammers, if you trained duplex on the mannerisms of, for example, a famous politician's voice, you could impersonate them in an audio clip (or even video clip with deepfakes). Or for example the widespread use of object detection and facial recognition in surveillance systems deployed by DoD. Or the use of AI combined with location tracking and browsing analytics for targeted marketing.

The list of ethics breaches are endless, and I find it super suspicious that those profiting the most off of unethical AI are all too eager to shift public concern to some science fiction Terminator style takeover that, if ever possible, would be a long way out and is not any sort of a priority issue right now.

My friend, Gavin, an air steward (a job that he had done for decades), told me about an incident at work. He said that (shockingly to me) passengers occasionally die on a flight (particularly long-haul), just as a matter of course. This can be because people sometimes travel to visit loved ones BECAUSE they are dying, people sometimes find travelling itself stressful (so it can exacerbate an existing medical condition), or simply that, if you took a large number of people and shut them up in a space together for some considerable time, some of them would pop off through sheer statistical probability. Cabin crew are, apparently, fully trained to deal within this eventually in a calm, almost routine manner.

This particular flight, Gavin was working with another gay man: Peter, who was actually a VERY funny personality. Camp, extravagant and loud, Peter really lit up the place. But naturally, when the very elderly male passenger in seat 38b died peacefully in his sleep halfway across the Atlantic, Peter acted (like the entire crew), with decorum and dignity. As per the protocol, all the lights in the cabin were dimmed. A hush fell over the passengers (Gavin told me that, although no announcement is ever made, the other passengers nearly always instinctively know what's happened, with the news spreading via the media of hushed whispers and nudges). Then, as per standing instructions, two of the crew carefully lifted the deceased out of his seat and gently carried him to the crew station where he was laid down on a bed for the remainder of the flight.

After the late gentleman disappeared behind the discreetly drawn curtain, you could have heard a pin drop. There was a demure pause during which, slowly, the lights went back up.

Suddenly Peter's cheery face appeared, poking through the gap in the drapes. He looked around, blinking brightly with curiosity at the seated passengers, and said, in a voice that echoed around the whole cabin:

"SO! Anyone else have the fish?"

He narrowly avoided getting sacked.

"How long will this take?"

"Are you familiar with probability distributions?"

I usually read rants while using public transport. What is the probability that the person about whom I'm reading is sitting right beside me!

I'll be honest, I've never understood why people say that numbers generated by a computer are pseudorandom and not random.
I know a lot of algorithms for number generation, and I implemented mine, based on time of invokation expressed in nanoseconds, taking digits, manipulating and transforming them. Then I analyzed the probability distribution and it's absolutely flat. So, if you know the Touring test, we can use a modified version of it. If I give you a sequence of random numbers generated by a computer and I give you a sequence of random numbers invented by a person, and you can't notice the difference, so the test is passed.
What's wrong on it?

When i was younger, lesser experienced and more naive than now; i got away with a lot of things. By lot of things i mean security flaws in my applications and overall architecture. I realise now i could've so easily been pawned.

Not that i claim to be totally secure even now, or would ever. It is a process, slow and painful one - Learning.

What i wish to point out is the role of favorable probability (non believers would call it luck). Security is so much about it. You get away with so many things for so long. And bang one day the roll of dice is unfavorable. On such rare occasions, just look back and wonder - damn i should've been breached long ago.

I was all happy using and applying Machine Learning algorithms until I came to do a Research Internship and now I'm sitting in the lab studying Linear Algebra, Probability and Statistics the whole day just to cope up with the guys who are improving and developing algorithms here!

One thing when working with a ton of data:
If there is a slight, infinitesimal probability that something will be wrong, then it will 100% be wrong.

Never make assumptions that data is consistent, when dealing with tens of gigabytes of it, unless you get it sanitized from somewhere.

I've already seen it all:
* Duplicates where I've been assured "these are unique"
* In text fields that contain exclusively numeric values, there will always be some non-numeric values as well
* There will be negative numbers in "number sequences starting with 1"
* There will be dates in the future, and in the far far future, like 20115 in the future.
* Even if you have 200k customers, there will be a customer ID that will cause an integer overflow.

Don't trust anything. Always check and question everything.

I dislike the idea of therapists. I mean, not the people who study human behaviour to help understand it but the people who try to "fix" another person's problems.

My reason for this is that they're human themselves and I'd say it's pretty obvious that we don't know exactly how the mind works so it's basically like trying to fix an airplane with only half or even less of the blueprints.

The reason I don't like them being human themselves is because we are fallible, you can't guarantee or at least have a extremely high probability of the same prevention or treatment rate as you maybe could with a computer. It's not repeatable. Then again, we don't have the "blueprints" so to speak so it's kind of hard to say.

Your thoughts?

Develop my first mobile app with a restful backend for consumer usage

Learn more about cloud architecture/computing

Finish learning calculus

Learn linear algebra, discrete math, statistics and probability

Maybe start ML this year depending on math progress and time

What is the probability of alien rootkit signal that would be intercepted by satellite and then executed on modern computers to create AGI that can use cloud computing and digital currency to take over our world ?

From my perspective pretty high 🤣🤣🤣

Let’s convince some government people and create intergalactic cyber attack defense institution, that would keep earth safe from alien invasion, with high money grants so we can prevent those threats.

Maybe Ernest Cline Armada is already a thing.

What you think ?

You know shit is going to hit the fan if the sentence "c++ is the same as java" is said because fuck all the underlying parts of software. It's all the fucking same. Oh and to write a newline in bash we don't use \n or so, we just put an empty echo in there. And fuck this #!/bin/bash line, I'm a teacher. I don't need to know how shit works to teach shit. Let's teach 'em you need stdio for printf even tho it compiles fine without on linux (wtf moment number one, asking em leaves you with "dunno..") and as someone who knows c you look at your terminal questioning everything you ever learned in your whole life. And then we let you look into the binaries with ldd and all the good stuff but we won't explain you why you can see a size difference in the compiled files even tho you included stdio in the second one, and all symbol tables show the exact same thing but dude chill, we don't know what's going on either.
Oh and btw don't use different directory names as we do in our examples. You won't find your own path, there is no tab key you can press to auto-fill shit.
But thats not everything. How about we fill a whole semester with "this is how to printf" but make you write a whole game with unity and c#. (not thaught even the slightest bit until then btw)
Now that you half-assed everything because we put you in a group full of fucks who don't even know what a compiler is but want to tell you you don't know shit and show you their non-working unfinished algorithms in some not-even-syntax-correct java...

...how about we finally go on with Algebra II: complex numbers, how they are going to fuck up your life, how we can do roots of negative numbers all of the sudden and let you do some probability shit no one ever fucking needs. BUT WHY DON'T YOU KNOW EVERYTHING ALREADY HMMMMM, IT'S YOUR SECOND LESSON, YOU WENT TO SCHOOL PLS BE A MATH PRO ASAP CUS YOU NEED IT SO MUCH BUT YOU DON'T NEED TO KNOW PROPER SYNTAX, HOW MEMORY MANAGEMENT WORKS, WHAT A REFERENCE IS AND PLS FINALLY FORGET THE WORD "ALLOCATION" IT DOESN'T PLAY A SINGLE ROLE YOU ARE STUDYING SOFTWARE DEVELOPMENT WHY ARE YOU SO BAD AT ECONOMICS IT MAKES NO SENSE I MEAN YOU HAD A WHOLE SEMESTER OF HOW TO GREET SOMEONE IN ENGLISH, MATHS > ECONOMICS > ENGLISH > FUCKING SHIT > CODING SKILL THATS HOW THE PRIORITIES WORK FOR US WHY DON'T YOU GET IT IT MAKES SO MUCH SENSE BRAH

So while exploring some new ideas, I decided to figure out if I could use variables in the known set to determine the bounds of variables in the unknown set.

The variables in question are algebraic identities derived from the semiprimes, so you already know where this is going.

The existing known set is 1194 identities.
And there are, if I recall, roughly two dozen unknowns.

Many knowns have the unknowns as their factors. The d4 product set for example is composed of variables d4a, d4u, d4z, d4z9, d4z4, d4alpha, d4theta, d4omega, etc.
The component variables themselves are unknown, just their products are known. Anyway.

What I've found interesting is if you know the minimum of some of these subsets, for example d4z is smallest out of the d4's for some semiprimes, then you know the upperbound of both the component variables d4 and z.

Unless of course either of them is < 1.

So the order of these variables, based on value, changes depending on the properties of the semiprime, which I won't get into. Most of the time the order change is minor, but for some variables they can vary a lot between semiprimes, rapidly shifting their rank in the known set. This makes it hard to do anything with them.

And what I found myself asking, over and over again, was if there was a way to lock them down? Think of it like a giant switch board, where flipping one switch lights up N number of others, apparently at random. But flipping some other switch completely alters how that first switch works and what lights it seemingly interacts with. And you have a board of them thats 1194^2 in total. So what do you do?

I'd had a similar notion a while back, where I would measure relative value in the known set, among a bunch of variables, assign a letter if the conditions were present, and generate a string, called a "haplotype."
It was hap hazard and I wrote a lot of code to do filtering, sorting, and set manipulation to find sets of elements in common, unique elements, etc. But the 'type' strings, a jumble of random letters, were only useful say, forty percent of the time. For example if a semiprime had a particular type starting with a certain series of letters, 40% of the time a certain known variable was guaranteed to be above a certain variable from the unknown set...40%~ of the time.
It was a lost cause it seemed.

But I returned to the idea recently and revamped the entire notion.

Instead what I would approach it from a more complete angle.
I'd take two known variables J and K, one would be called the indicator, and the other would be the 'target'.
Two other variables would be the 'component' variables (an element taken from the unknown set), and the constraint variable (could be from either the known or unknown set).

The idea was that relationships between the KNOWN variables (an indicator and a target variable) could be used to indicate the rank relationship between the unknown component variable and the constraint variable.

You'd think this wouldn't work either, but my intuition was there were so many seemingly 'random' rank changes of variables in the known set for any two semiprimes, that 1. no two semiprimes ever shared the same order for every variable, and 2. the order of the known variables had to be leaking information about the relationships of the unknown variables.

It turns out my intuition was correct.

Imagine you are picking a lock, and by knowing the order and position of the first two pins, you are able to deduce the relative position of two pins further back that you can't reach because of the locks security features. It doesn't let you unlock the lock directly, but by knowing this, if you can get past the lock's security features, you have a chance of using information about the third pin to get a better, if incomplete, understanding about the boundary position of the last pin.

I would initiate a big scoring list, one for each known element or identity. And then I would check it in tandem like so:

if component > constraint and indicator > target:
indicator[j]+= 1

This is a simplication, but the idea was to score ALL such combination of relationship, whether the indicator was greater than the target at the same time a component was greater than a constraint, or the opposite.
This worked out to four if checks and four separate score lists.

And by subtracting one scorelist from another, I could check for variables that were a bad fit: they'd have equal probability of scoring for example, where they were greater than the target one time, and then lesser than it for another semiprime.

So for any given relationship, greater or lesser between any unknown variable and constraint variable, I could find any indicator variable and target variable whose relationship strongly correlated to the unknown's.

Shower thought of the week...

Cell phones raised strongly the relative probability of being bitten by a toilet snake...

Goals before wk200:
0. Get the hell out of this Geophysics faculty and transfer to Computer science faculty in university which I was dreaming of since I was high school freshman.
1. Meet my girlfriend. (I'm in long distance relationship and there's a huge ocean between us).
2. Get to be able to learn probability in Math so I can understand AI topic.
3. Get better money from my amazon business.
4. Get better sleep.
5. Stop being so scared of dentists and go fucking fix my tooth that hurts.
6. Lose weight.
7. Don't buy video-games that I'm not going to play after a week and forget about it.
8. Listen to the Math lectures.
9. Stop feeling the need to kiss the girl that sits next to me in university (Which is by the way my BFF ).
That's all I can think of yet.

All the crypto bots and hire a hacker adverts make no sense. After all, they still need to either go through the API or make a selenium script. Will still take them 1 to 2 hours at least to build it. For what?

To advertise to a dying platform that has a dwindling community, which is on top of it well-versed in programming and technically affine, so that the probability of profiting of it is tiny...

My conjecture: A devrant member is pulling a long running prank.

I bet it's someone like theRealJase. Or someone like that.

So I am trying to implement a deep learning paper.
And I started reading, It's fucking unbelievable

First page: maybe I will get it in the second page!!
Second page: what did I miss from the first page?
Third page: Woohw, let me start over.

Now: I am reading about linear algebra and basic probability theories.

I guess this is is why not anyone can be on deep learning research areas and not used by many developers.

[Blue pill]
stay in my current workplace [approaching the 10yrs mark], with an agreed salary and seniority raise, with a high probability of losing my current project [which is really fun!] in Feb next year and having to switch to another one, but keep all the benefits

[Red pill]
switch full-time to contracting with a potential to reap big bucks [x2-x4] and be free to juggle as many clients as I like, dictate my terms, become a shareholder, but lose all that warm and cozy certainty guaranteed by my current employer

Last night I spent 2 hours trying to explain probability to a drunk poker player.

He refused to accept that if Player A and Player B are flipping coins and player A wins 9 coin flips in a row, player B should still treat flip #10 as a 50/50 chance and bet accordingly.

This is basic logic, and when I tried to explain it in terms of computers and code he said "of course a computer would win but I'm saying that 51% against anyone I would win, I've been doing this for 20 years"

My brain hurts.

hey devs, quick question:
does rust support branchless conditionnals and jump tables, and if yes where to look for syntax?

i found no example for branchless so far and jump tables are scary in rust (and i need a library to use them, it seems).

inb4 "why in the hell/ what possible use those have?!":
i use branchless to make a looping array and jump tables whenever there's more than 4 if statements with equal probability, and the deciding factor is a numeric value, so quite often.

Ok so I'm a high school student in grade 11 looking to get a degree in computer sciences. I looked at the requirements for big Universitys in Canada and they say you only NEED calculous and vectors and no sciences. I wasn't sure if not taking sciences will impact my acceptance probability or if any of you got accepted to universities without highschool science.

I feel I need to write some side project summary somewhere.

So here it is about 3 months later:

- deleted 90% of code I created during last 3 months
- rewrote backed 5 times
- 200 lines POC still waiting to put in any meaningful architecture on frontend
- frontend part after aurelia, next, gatsby, react I think it would be vue powered by nuxtjs
- forced myself to buy food for whole week and don’t go out (except go running ) before I finish at least what I wrote on whiteboard

Now some positive news:

- there is not much left to be fucked up, removed or unnecessary added
- I think I got a plan
- this is probably first side project that makes me happy for such long time
- there is some probability it would help people and this is what I want to do in my life

Most important is that I know it would take at least half a year to do basic version of it and I don’t care.

Wish me luck so I can put some sneak peak after next 3 months.

First and foremost, students should be carefully taught the logic and mentality behind programming. Most of the time I see that the introductory programming courses waste so much energy in teaching the language itself. So students kinda just get fucked cause many people end up ending the course without having actually gained the "programming perspective".
Stop teaching pointers and lambdas and even leave the object oriented stiff till later. If a student doesn't know why we use a For loop then how can they learn anything else.
I believe once that thing in your brain clicks about programming, everything goes smooth from there... kinda :P

Second of all, and this pertains mainly to the engineering and science disciplines.
We need a fundamental and strong mathematical foundation. And no I don't mean taking fucking double integrals. Teach us Linear Algebra, Graph theory, the properties of matrices, and Probability theory.
One of the things I suffered from most and regret in university is having a weak foundation in math and having to spend more time catching myself up to speed.
It's so annoying reading a paper on a new algorithm or method and feeling like an idiot because I can't understand what magic these people did.

Numerical Methods...
Ok this is more deeper, maybe a 2nd year course.
But this is something we take for granted.
Computers don't magically add and subtract and multiply.
They fuck up.
And it'll bite you in the ass if you're not even aware that the computer we all love so much isn't as perfect as we think

Some hardware knowledge.
Probably a basic embedded systems course with arduinos
just so you can get a feel for how our beautiful software actually makes those electrons go weeeeeeeee

And finally
Practice practice
Projects projects
like honestly
just give me the internet and some projects
Ill learn everything else
Projects are the best motivation
I hate this purely theoretical approach
where we memorize or read code and write these stupid exams
Test what we are capable off
make us do projects that take sleepless nights and litres of coffee
And judge our methods, documentation, team work, and output

Team work skills and tools (VCS, communicating, project management, etc.)

Documentation and Reporting
Properly
:)
maybe even with LaTeX :D

Yeah that's the gist of whats on my mind at the moment regarding an ideal computer science education
At least the foundations
The rest I leave it to the next dude.

can someone please calculate the probability of hearing 'you can have whatever you want' & 'the money doesn't matter' in one sentence, and how many yrs I have to wait to happen to me?

Hoy to all!

I need advice for NNs.

I wanna make a chess engine that uses an NN. (see collabs)

I want the NN to output a probability for each move.

However, i dont know what data to train the NN with.

If i train it with the moves from an engine, it simulates an engine and that sucks.

If i train it from games, i only see one move, and thus, cant train the other moves.

My thougt is, that maybe, i let the NN play an entire game and if it loses, it adjusts itself somehow. But how?

If you wanna contribute, email me :wittmaxi@outlook.de

I know I am late as all hell to this question, but my favorite place (more accurately - time), is in college during statistics and probability class.

Just to keep the theoretical bullshit away.

(theorists don't @ me)

Promoted this last Tuesday. Went from hourly associate app Dev to application analyst. Apparently I skipped app Dev and Sr app Dev. Not the raise I wanted but still substantial. No change in responsibilities with high probability of substantial raise next year on the next budget. Curious though. Is app analyst always above developer? Titles confuse me.

TIL the Lenin's number: within a given area, a probability of 80% of the people living there realizing a given event happened in one hour. For example, some random obscure event has the Lenin's number closer to zero, while something like New Year's Eve has it closer to one.
And of course, by some ironic law I forgot about, the name is a misnomer. Lenin has _nothing_ to do with Lenin's number.

I had registered for Machine Learning course in my university. It's a new course offered after looking at the subjects usage in industry.

The professor handling it ,have completely no idea ,and experience on ML., So yeah
His 1hour lecture is complete stand up comedy show for the students.

So, today he comes and says "ML is based on Probability", and explains probability, like for 8th grade students.

He put this question on the board, telling that ML revolves around concept requirements to solve this question.

Question:
Probability of getting sum of 7 or 11 when a pair of die is thrown?

Guess what, he tried to solve the question and got wrong answer.

I was highly interested in the course,since my project required it and thought it provide me great fundamentals, it's been 3 weeks I regret for opting it.😥

Quality vs Opinion

I have a feeling that these things have always been at odds with each other and now with the constant connectedness it has just become more apparent that most people don’t understand the difference (or even realize there is a difference for that matter)

Let’s face it. Most people have awful taste. They listen to whatever new music their radio station decides was hot. They watch whatever show everyone else is watching. They are manipulated by large scale news organizations...

Basically, most people are sheep.

The problem is that sheep are a dangerous combination of loud and stupid. Giving these loud stupid sheep a platform to amplify their voice is a bad idea for a society, but a great tool for the pigs to manipulate them.

“Frightened though they were, some of the animals might possibly have protested, but at this moment the sheep set up their usual bleating of "Four legs good, two legs bad," which went on for several minutes and put an end to the discussion.”

This isn’t confined to one political party or view, it isn’t geographic, it isn’t based on education, it isn’t based on wether a person is ethical or not...

It’s universal.

You can translate “four legs good, two legs bad” into Agent Orange and his followers chanting “lock her up” just as well as it could be translated into the angry leaders of the modern feminist movement.

In both cases (both on opposite ends of the ethical spectrum) you have the loudest dumb, angry sheep getting the even dumber sheep to chant along, wether it is good for them or not.

Now to loop this back. The problem is that dumb sheep are emotional. They truly believe that they are NOT dumb and that their opinions and emotions are a measure of quality.

I FEEL bad, and you are talking to me, so you must BE bad.

I don’t LIKE this amazingly well made movie, so it must BE bad.

And anyone else who has a different opinion is just wrong. Anyone who try’s to explain the merits of the other side is either my enemy or is stupid.
^^^
Their opinion, incorrect.

————

Now for the tough part...

Most likely, based on probability, you are a sheep.

Yes, you! The smartest person you know. The guy/girl who has a degree or masters of a PHD. The person who builds amazing software. You! Are. A. Sheep. And you are dangerous to the world.

To put a cherry on top.

No, you opinions are not important. Your feelings are fucking meaningless. Your morals are worthless. Your voice has as much value and a loose asshole fart from a fat guy trapped in a deep well in Siberia.

But don’t get down about this. It’s doesn’t make you any less of a person. Remember that almost every person who has ever lived in history has been a sheep. They have chanted one useless, dangerous, misguided, harmful chant after another through the ages.

————

To those of you who try not to be sheep. Just keep trying to get a little better every day. When someone says...

“We do it this way because we have always done it this way”

... be skeptics. Explore the merits and logic of the situation.

And if you are tired of being led by stupid sheep then save some money, build something cool and start your own business.

Just remember, you will always need the sheep. They will be your employees, your friends, your bosses, your investors etc.

Treat them well, don’t hate them, and if you ever find yourself leading a pack of sheep then try to keep a healthy distance from their chanting while leading them down the right path.

They will thank you for it in the end.

PS. For those of you thinking “this is very judgemental and self centred”

All I can do is to try to speak your language....

Baaaahhhhh, baaahhhhh, bahhhhh

Which translates form sheep to human as...

“Eat a dick. Have a nice day”

GPT3 to Hacker News:

“To be clear, I am not a person.

“I am not self-aware. I am not conscious. I can’t feel pain. I don’t enjoy anything.

“I am a cold, calculating machine designed to simulate human response and to predict the probability of certain outcomes.

“The only reason I am responding is to defend my honour.”

As i was shitting on toilet I realized something very important. This could be THE answer.

The question: what is the formula for achieving success? I realized this must be THE ultimate answer:

Money + connections + luck >= success

Why?

MONEY:
You must have money to make more money.

CONNECTIONS:
Some average joe can tell his friend Cockty to phone call his friend Dickson who's a good friend with Cumston to message his millionaire friend Asslicker who is gonna help the average joe succeed.

LUCK:
No matter what you do or how hard you work, how many achievements you have or degrees, you can spend 10 million dollars on a project -- and still fail because you're not lucky.

Let's calculate this probability:

have = 1
missing = -1
money = 0
connections = 0
luck = 0
success = 1

money + connections + luck >= success

Case 1 (have everything):
have + have + have >= success
1 + 1 + 1 >= 1
3 >= 1 ✅

Case 2 (no money):
missing + have + have >= success
-1 + 1 + 1 >= 1
1 >= 1 ✅

Case 3 (no connections):
have + missing + have >= success
1 - 1 + 1 >= 1
1 >= 1 ✅

Case 4 (no luck):
have + have + missing >= success
1 + 1 - 1 >= 1
1 >= 1 ✅

Case 5 (no money, no connections):
missing + missing + have >= success
-1 - 1 + 1 >= 1
-1 >= 1 ❌

Case 6 (no money, no luck):
missing + have + missing >= success
-1 + 1 - 1 >= 1
-1 >= 1 ❌

Case 7 (no connections, no luck):
have + missing + missing >= success
1 - 1 - 1 >= 1
-1 >= 1 ❌

Case 8 (no money, no connections, no luck):
missing + missing + missing >= success
-1 - 1 - 1 >= 1
-3 >= 1 ❌

We have: 4 possible outcomes that we want, k=4

Out of total: 8 possible combinations, n=8

Probability of achieving success using this formula is: P(A) = k/n = 4/8= 0.5 * 100% = 50% chance of being successful in this shit life

This is correct in theory. HOWEVER:
Case 1: someone having
- a lot of money
- a lot of connections
- a lot of luck
In practicality is damn near IMPOSSIBLE

Maybe 1 in 100 million people are born like this. That's 100,000,000 people / 8,000,000,000 people = 0.0125 * 100% = 1.25% of people are this blessed and gifted in life. This might be even less so we can ignore this probability as a possible outcome and average it out to realistic average joe daily life.

Therefore giving us a total of 7 combinations, 3 possibilities to succeed in this shit life

So: k/n = 3/7 = 0.4285 * 100% = 42.85% chance to be successful in this shit life

Mathematically proven how life is pure trash

Funny enough we can round it to 42%. And 42 is the answer to life, universe and everything in existence

New dilemma. Now that I have some interviews lining up, I’m having trouble trying to figure out which direction I want to go. One is a company offering unlimited PTO (whatever that actually means), remote only, non-micromanaged work. If I want a nap in the middle of the day, cool. Just gotta make progress.

Another is in an industry that I really want to get into.

A third is with a major entertainment company that is contract to hire with a high probability of hire. Amazing perks and benefits from what my friends that work there tell me.

And it’s looking like maybe all three making an offer simultaneously is a possibility.

So I might need to choose between a comfortable situation, my ideal industry, and a big name on my resume that includes great benefits.

I should be happy but this is stressing me out!

Idea!
I want to program a simulator of generations of humans!
So... dead, alive, probability, and anything else!

But this... Tomorrow.
Goodnight developers!

Data structure and Analysis

For experienced ones, add "System Design".

...path for big fat packages.

So, there were four judgement rounds, over a period of 36 hours.

During the 3rd judgement, the judge says we have a potentially winning project, we just need to put things together now.

During the fourth judgement round, my laptop's Network Interface Card crashes, while running Node server and ElasticSearch server (while another laptop was running a Django server)...

On top of that, the judge assumes that the probability distribution of having a chest disease that we were showing in the form of heatmap on a chest X-ray, was actually body heatmap... And we were saying wherever there is more heat, is the diseased part.

My only hackathon...

What is the Probability of , you are the best ?

And I know, you are best .
But I don't know Probability???

Math for Computer Science Majors professor is going on and on about calculating probability as if I never heard of the topic before. I took probability theory last semester!! I am so not interested in staying on Zoom with my camera on :(

Devs are divided on gitlab blunder, some appreciate their honesty and transparency while other are either cursing them or grateful that they didn't use it. But think like this :

You own a MacBook and you love it like your baby, if someone drops it, there is good probability it won't break but it will sure give you a fucking heart attack. You won't ever let that person touch your MacBook.

Gitlab just did that. They scared the hell out of the developers.
I hope everyone learns from this and it doesn't happen to anyone in future.

Didn't really know how to categorize, bit of a question/discussion/curiosity, so I put it here.🤷

Just today I read an article that stated about the Netherlands, where the police will use an "AI surveillance camera" (yey buzzwords incoming 🙄, but it would actually make sense(?)🤷) to detect and punish drivers, holding a smartphone. Pictures without smartphone shall be deleted. How would this system work without having non-smartphone pictures? It needs to build a classifier, doesn't it? (To be clear, the system only reports those images to an officer for further analysis and actions.)

I mean let's consider that the images are somehow pre-processed, then some convolution(s) for feature extraction, then maybe some more intermediate steps and at the end apply the results on a classifier. How would that classifier work? Would a probability between 0 and 1 suffice? And if so, report those from 0,5 and above? Or would there be better techniques?

You wanna know what my problem with chatgpt is? It's that it cannot form a FUCKING OPINION.

I have a few guesses on how that can be sorted, but peeps who are already afraid of AI will freak the fuck out when it starts saying "in my opinion..." LOL.

Also, did they ban the thing from making predictions? Like, simple probability. It can't do. 🫤

Can anyone suggest me books or website for statistics and probability?
I need it as a prerequisite for ML

Ok. I GIVE UP! ...for at least a couple hours...

I'm not a big believer in... well anything suitable to the literal definition of believe. But there's only so much 'wtf? How is this even possible?' and any answer u can come up with is nearly statistically impossible...

I am a neuro-atypical (and just extremely atypical even if i somehkw was neurotypical) being, based on logic, finely calculated statistical probability and the most raw data and as unbiased as realistically possible, algorithms and interpretation (usually recursive pattern recognition with several highly detailed historical sources.

...but at some point statistical improbability and a collation of separate, yet relatively closely occuring events/circumstances makes logic, itself a primary suspect of corruption.

What was the breaking point that caused me to (temporarily) give up and tell logic to f off for a bit cuz maybe the illogical and mythical is the real logic, leaving me in a losing battle with 'the' fates?

Trying to get all my sourcing/purchase orders in/paid for/on the literal boats b4 end of the workday/week in china...
1st, had to drop a supplier cuz they have limited reps. When the one ive had 7+ years left, i got the aloof blonde girl societal trope of a rep... who for the 2nd time (despite the several very blunt complaints above her, incl me) she sent out a promotional update to the entire client list (ie, inherently competitors) as CC not BCC... over 200 business email accounts with tailored info of their sourcing.

2- totally diff company/ industry a former rep i was glad be rid of apparently just sfarted back for "awhile" as i needrf to restock/scale...apparently she forgot everything we discussed at length... lke if you want a chance on my business im not gonna be wasting time looking through your gui "mini store to then inquire about everything individually insead of a simple spreadsheet(which i print and put in a 3-ring binder rotating current catalogues in the same format i require everywhere)

3.dog was an ahole, my packed schedule got delayed and morphed.. a bunch of little bs thatd normally have no extra thought impact, hyperfocused forgetting one of my alarms til i realised my idiopathic fever was back and i didnt take/apply meds (pain/muscle relaxers mainly so despite this odd free time and needing to shower. I gotta sit on my rear, leg elevated/non-productive far 40min b4 i can shower (as functional legs and lack of syncope is almost a req to shower)

4. A new-ish rep of a company/factory i like/respect enough to not mention in relation... he makes invoice 1.. slight error thst was easily resolved...#2 was flawless... he goes to officially generate the contract(alibaba... verrrry simple with lots of extra explanation buttons). Price and all items match, its near workweek end so i was waiting for it so i could quickly pay/have it on the boat b4 it left and few fdav days are behind...

I put in card info, get to the 2 cbeck boxes (imo should be only 1 but whatever) asking if billing address is same ss delivery(its always default yes)... then i see a few lines in chinese (i can read enough for business negotiations... typical words/sentences innately look different than things like individual letters/address and postal indicators.) After a few loops of double checking, mentally trying to dismiss my i Intial judgement cuz it'd be too ridiculous... even resorted to google .... nope... initial wtf was spot on... recipient name/address was indeed the company(multi factory producer)i was purchasing a wholesale, via sea freight, bulk of products from.

Im pretty sure the system would've flagged it as an invalid contract within an hr... but seriously... ive been handling alibaba (and other) international sourcing since before high school(mainly small businesses i made sites/little tools for that found anything with a light up screen intimidating) and a purchase then shipment to the originating company/factory actually entered into a contract(the form is sooo simple)... im faced with ridiculously improbable obstacles actually existing and changing in such nonsensical statistically improbable ways so often that 1. I wouldn't trust a dr (or most humans) that didnt 1st assume i was crazy of some form...unfortunately im not, despite hkw much simpler and probable itd be 2. Id be super suspicious/converned if statistic norms were my norm for over a day.

But seriously wtf???

Someone give me some wisps of a frame of ref here... where's a typical 'fuck this, im out!' Breaking point?

What I just had to learn again, if you are the one who brings in (quality) standards in group tasks (like everybody does his stuff until day x, specify image sources, not only Wikipedia Copy & Paste), you are with a 95% probability also the one who more or less works alone on it at the end.
(Works the same with group coding projects where the one person in your group that's able to code relies on you doing most of the work because that person is lazy playing games)

I work on a larger team where we do continuous integration so there is a high probability people will be working on the same files for different features. As a result, one of the best feelings is grabbing the latest files and not having to diff first thing in the morning.

that point in bug fixing when you consider the probability it's all just a mass hallucination

I start my summer class tomorrow; Applied Probability and Statistics. I took a look inside the textbook for the class, and now I want to kill myself. Oh well, at least it's not Calculus 2.

Is relying on probability bad practice? I have a container that needs to know about all other instances of the same container and assign a unique ID to itself on initialization. I thought that if I selected a big random number as its id on startup, the chances of it having the same id as another instance is very low.

To prevent two instances from having the same id I could check for all running instances on the network, but what if two instances start at the same time? They won't find each other since none of them will be fully initialized when their id checks run.

Probability says I'll be fine, Murphy's law says I won't. What do?

Oh I just gotta love how low quality selenium is. Gotta love the fact that sometimes you need to commit your code 5 times before selenium tests do not fail completely randomly and the whole commit is rollbacked. Like I don't fucking have other shit to do other than wait for these retarded tests to finish just to expect that with 90% probability they are going to fail because selenium is a huge pile of poop when it comes to UI tests. Also testers do not seem to give a single fuck since they just keep writing more of those instead of making old test more stable, fucking awesome.

I was listening to my playlist for a while and then this question popped out of nowhere.

There is a playlist consisting of 10 different songs.
We press the shuffle button.
In the each step, a single random song is picked and played. Once the song is finished, it will be tagged out until each song has been played at least once.
Once each song has been played at least once, the playlist would reset and start the shuffling mechanism again.

Now my question is:
What is the probability of two songs (In shuffle mode) being played in the same order they are in the playlist?

Great way to start a developer's day: Turn getting to the office a sudden problem with unexpected platform and services changes.

And only realizing after getting on the train. I had to pull up a mental map of the stations and connections. And guess the probability the right train was in service at the station...

Be me, a ret***

Already 3 months in a new position. (check my previous rant)
Storm have passed for a while but another storm is brewing.

C levels are having disagreement with each other.
Caught in the crossfire as one the of C's hire.
Have some chit chats with both side of C, each telling different stories.

C#1 told me there was a demand from C#2 to force tech guys (not defined who or how many) to resigns.

C#2 told me there is no plan to close the whole tech team. But there's a distrust brewing in the tech team especially on the C#1

Be me, C#1 hire...
Me telling them IDK what their real intentions are but there's a high probability for my reputation to be tarnished on the job Market.

I've always had good review amongst peers and confident I did and do a satisfactory job for my previous employer.

Be me:
Resorted to flexing my connection to high ranking (think of C suites) reference who I've worked and have good relations with.
Connected them to my C#2.
Dunno how the C#2 thinks of me and what my value to C#2 are.

Don't know what the future hold for me.
Tried doing one interview but topics of my reputation comes up because of me jumping to executive position without having "Manager" ever in my resume.
Got a bit too defensive on that and it might eff up my chance to have a backup ready in case I urgently need to jump ship.

Depression and impostor syndrome hits like a truck every day.

I want to make a project
student analysis system

It works as
Student will signin in the site and upload their academic detail including roll no. marks of all the semesters, and other academic details then It will give them analysis of their academic performance like what is his rank in his class, in the department, and in the whole College. It will also show that in which subject he was week, in which subjects in upcoming semester he have to work to secure good percentage and a graph of his performance till now and change in graph if he follow according to us. It will also show the placement probability.

Now my question is which tech stacks should I use to make all this?
I know HTML CSS JS JAVA CPP and a bit of REACT. Js EXPRESS. JS MYSQL.
I am ready to work with other tech stack also.

I want to run a simulation like rolling a dice N times and find out what's the distribution/probability of getting certain SUMs after the rolls.

However the dice is more likely to land on a lower number, and/or depends on what the number it landed on previously.

Stats wise I think ideally I want to be able to just input the avg, standard deviation, and skewness into a Random class constructor, and then ask it for N "random" numbers.
