When it comes to users, perception is everything.
The task: Choose x random contractor numbers for us to assign to y jobs.
Me: How many contractors are there?
Mgr: 25
Me: How many jobs need assignment?
Mgr: 25
Me: Does the program need to assign contractors to individual jobs?
Mgr: No, we just need the 25 contractor numbers
Me: Well in that case just use the list I gave you earlier.
Mgr: No, we can't do that. It won't be random
Me: 😑😑😑😑😑
Fix? Return a list of 25 contractor numbers in a slightly different order than the one originally submitted (5 or 6 items moved around)
The manager was pleased.3 -

Whoever implemented the data import in Numbers on Mac needs to be lined up against a wall and shot with needles until they wish they were dead.
Why on all of gods unholy green and shitty earth would i want data i import (EVEN IN CSV FOR FUCK SAKE) to be delimited by an arbitrary text width? WHAT THE ACTUAL FUCK
WHY WHY why would I EVER want to delimit my carefully structured data by fucking text width instead of new line or comma? AAAAARRRHHH
And what fucking big brain genius made this the DEFAULT SETTING for imported text AND CSV FILES. IT STANDS FOR COMMA SEPARATED FILE YOU FUCK BOI MAYBE JUST MAYBE I WANT IT SEPARATED BY FUCKING COMMMMMMMAAAAASSSSSS9 -
Worst error message management.
Can't you just display the valid pattern for an username instead of showing different error message everytime.

Can I use ANY phone number in my game?
According to Wikipidia:
"Numbers between (555)-0100 & (555)-0199 are reserved for fictional use."
But.. I'm wanting to have a little phone pop up in my game that you can enter phone numbers into and text the corresponding player (and i hope to have more than 99 players) I would just have contact names, but I want players ti be able to dick around with other players.. Like, post their number to in-game telemarketers and such. What fo you think I should do?29 -

math be like:
"Addition (often signified by the plus symbol "+") is one of the four basic operations of arithmetic; the others are subtraction, multiplication and division. The addition of two whole numbers is the total amount of those values combined. For example, in the adjacent picture, there is a combination of three apples and two apples together, making a total of five apples. This observation is equivalent to the mathematical expression "3 + 2 = 5" i.e., "3 add 2 is equal to 5".
Besides counting items, addition can also be defined on other types of numbers, such as integers, real numbers and complex numbers. This is part of arithmetic, a branch of mathematics. In algebra, another area of mathematics, addition can be performed on abstract objects such as vectors and matrices.
Addition has several important properties. It is commutative, meaning that order does not matter, and it is associative, meaning that when one adds more than two numbers, the order in which addition is performed does not matter (see Summation). Repeated addition of 1 is the same as counting; addition of 0 does not change a number. Addition also obeys predictable rules concerning related operations such as subtraction and multiplication.
Performing addition is one of the simplest numerical tasks. Addition of very small numbers is accessible to toddlers; the most basic task, 1 + 1, can be performed by infants as young as five months and even some members of other animal species. In primary education, students are taught to add numbers in the decimal system, starting with single digits and progressively tackling more difficult problems. Mechanical aids range from the ancient abacus to the modern computer, where research on the most efficient implementations of addition continues to this day."

TL;DR - Girlfriend wanted to learn coding, I might have scared her off.
Today, my girlfriend said she wants to learn coding.
Me: why?
She: well, all these data science lectures are recommending Python and R.
Me: Ok. But, are you interested in coding?
She: No, but I think I have to learn.
Me: Hmm.. coding requires a clear thought process, and we should tell the computer exactly what needs to be done.
She: I think I can do that.
Me: Okay... then tell the computer to think and give a random number between 1 to 10.
She: I will use that randint function. (She has basic knowledge in C)
Me: Nope. You write your own logic to make the computer think.
She: What do you mean?
Me: If I were you... Since it is just a single digit number.. I would capture the current time and would send the last digit of milliseconds @current time.
She: Oh yeah, that's cool. Understood! I will try...

I was working on a project lately where I needed to convert an array of bits (1s and 0s) to floating numbers.
It is quite straightforward how to convert an array of bits to the simple integer (i.e. [101] = 5). But what about the numbers like `3.1415` (𝝿) or `9.109 × 10⁻³¹` (the mass of the electron in kg)?
I've explored this question a bit and came up with a diagram that explains how the float numbers are actually stored.
There is also an interactive version of this diagram available here https://trekhleb.dev/blog/2021/....
Feel free to experiment with it and play around with setting the bits on and off and see how it influences the final result.

Teaching my homeschooled son about prime numbers, which of course means we need to also teach prime number determination in Python (his coding language of choice), when leads to a discussion of processing power, and a newly rented cloud server over at digital ocean, and a search of prime number search optimizations, questioning if python is the right language, more performance optimizations, crap, the metrics I added are slowing this down, so feature flags to toggle off the metrics, crap, I actually have a real job I need to get back to. Oooh, I'm up to prime numbers in two millions, and , oh, I really should run that ssh session in screen so it keeps running if I close my laptop. I could make this a service and let it run in the background. I bet there's a library for this. He's only 9. We've already talked about encryption and the need to find large prime numbers.3

in Germany usually like this:
1.000,00

now i wonder how to type a number, whenever i have to use german software
should i use the US way, the german way or the dev way? the wrong one could possibly break it11 -

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?14 -

Can someone explain me AI/ML/DL in traditional algorithmic way without AI jargons?
What I currently understand is that they convert the training data to numbers based on a complex black boxed mathematical algorithm and then when a new data comes in, the same conversion is done and a decision is taken based on where the the new number fits in within the geometry/graph plot of the old numbers from training. The numbers are then updated. Is this what they call AI? Nearest number/decision search?
Kindly try to avoid critic, I am having a difficult time understanding the already trending AI stuff. People say that the algo exists from long back but only now we have the compute power.22 -

While I was exploring multiplication tables I stumbled on something cool.
Take any power of 2 on the multiplication chart.
Now look at the number in the bottom left adjacent box.
The difference of these two numbers will always be a Mersenne number.
Go ahead. Starting on the 2's column of a multiplication table, look in the bottom left of each power of 2 and get the difference.
2-2 = 0
4-3= 1
8-5 = 3
16-9=7
32-17=15
etc.
While the online journal of integer sequences lists a lot of forumlas, I just wrote what came to mind (I'm sure its already known):
((2**i)-(((2**i)/2)+1))
The interesting thing about this is it generates not only the Mersenne numbers, but if you run i *backwards* it generates *additional* numbers.
So its a superset of mersenne numbers.
at i = 0 we get -0.5
i=-1 -> -0.75
i=-2 -> -0.875
i=-3 -> -0.9375
i=-4 -> -0.96875
And while this sequence is *not* mersenne numbers, mersenne numbers *are* in this set.
Just a curious discovery is all.10 -

Following on from my previous SQL script to find prime numbers
https://devrant.com/rants/2218452/...
I wondered whether there was a way to improve it by only checking for prime factors. It feels really dirty to use a WHILE loop in SQL, but I couldn't think of another way to incrementally use the already found prime numbers when checking for prime factors.
It's fast though, 2 mins 15 seconds for primes under 1,000,000 - previous query took over an hour and a half.

wk48 best question:
My go to question for dev interviews is how do you find all prime numbers from 2 to x because there's so much room for optimisation.
Start with the basics, loop over every number and check if it's divisible by any number less than it, then record the prime numbers and check only those, then move to something like the sieve of eratosthenes then reduce the problem space and only iterate through 2 to sqrt(x)5 -

Though I demonstrated a hard upperbound on the D(10) dedekind in the link here (https://devrant.com/rants/8414096/...), a value of 1.067*(10^83), which agrees with and puts a bound on this guy's estimate (https://johndcook.com/blog/2023/...) of 3.253*10^82, I've done a little more work.
It's kind of convoluted, and involves sequences related to the following page (https://oeis.org/search/...) though I won't go into detail simply because the explaination is exhausting.
Despite the large upperbound, the dedekinds have some weirdness to them, and their growth is non-intuitive. After working through my results, I actually think D(10) will turn out to be much lower than both cook's estimate and my former upperbound, that it'll specifically be found among the values of..
1.239*(10^43)
2.8507*(10^46)
2.1106*(10^50)
If this turns out to be correct (some time before the year 2100, lol), I'll explain how I came to the conclusion then.8 -

Can someone walk me through an entire process, showing your math & work, using some very small, single- or double-digit primes? Such as if I were to encrypt the text "hello world" using prime numbers like 3, 5, and 710 -

I don't know. I just can't get excited about numbers.
I'm a builder. I'm excited about things working from start to finish.
Id be excited about numbers if it was from 0 users to 100 users.
Not 10000 to 10500.
That's not an engineers job, is it?8 -

wait,
if there are 3.4 Billions FaceBook fake users, that means than there are also at least 3.4 Billions fake email accounts around. Jeez.
And the spam traffic estimates are at 260Billions email per day or 260B/3.4B=76 emails sent by each fake email accounts per day. Much less as probably fake email accounts are more.
So, only 76 spam emails sent per account per day. I think there is still room for a big improvement5 -

This morning I was exploring dedekind numbers and decided to take it a little further.
Wrote a bunch of code and came up with an upperbound estimator for the dedekinds.
It's in python, so forgive me for that.
The bound starts low (x1.95) for D(4) and grows steadily from there, but from what I see it remains an upperbound throughout.
Leading me to an upperbound on D(10) of:
106703049056023475437882601027988757820103040109525947138938025501994616738352763576.33010981
Basics of the code are in the pastebin link below. I also imported the decimal module and set 'd = Decimal', and then did 'getcontext().prec=256' so python wouldn't covert any variable values into exponents due to overflow.
https://pastebin.com/2gjeebRu
The upperbound on D(9) is just a little shy of D(9)*10,000
which isn't bad all things considered.4 -
This internal api is killing me. Why the fuck do people return an array of numbers inside a field that has a generic name such as `icons` to convey information such as "hasOptionFooIncluded". Because of course then icons contains '6'. Yet if both 6 and 4 are in there, it means something else. Needless to say there is no documentation whatsoever what each number or group of numbers actually means so I have to ask around to find out what numbers means what in order to wrap that call away into something maintainable. Because the API is deprecated and we don't want to fix shit in there. We just create other shit depending on this crappile. :/
Stop using magic numbers. Just stawp it! -

I got two phone numbers, first is prepaid registered for me, second is on some shitty plan registered on my company.
Today I am trying to merge those two numbers to be company numbers and first one should be main number.
Have been in telco company office twice already.
2,5 hours and still no success.
Now I got back home and waiting for phone call from consultant because some software is not working and he can’t do anything right now.
I got used to fact that the bigger company the more shitty software it have and nothing is working as expected but it is happening to me every time I try to improve my life and make it simpler.
Fax was more reliable then todays software.

A few weeks ago a friend was teaching me about 16bit numbers because we were making one in C# with a function, but he said we need two numbers for the function to work.(so as an example were gonna use 0, 2)
Now I didn’t understand how two numbers were supposed to make one. And my friend could not explain it to me. So I researched the topic all day and the epiphany happened I realized I was looking at it all wrong. I shouldn’t be looking at it as 2 decimal numbers but 2 binary values or two binary arrays forming one byte array with a length of 16.7 -

A long time ago, I used AIDE (Android IDE) to write a simple application to output random numbers for the lottery. I test it out and head to the gas station. I pulled out my phone to generate numbers, and received something like 36892789, 3, 78921593, 5.
After hours of staring at my code, I transferred and compiled with Eclipse and the problem disappeared.4 -

Why is assigning something to a variable then returning it a code smell?
Simple example:
double makeNumber(String[] numbers)
{
StringBuilder sb = new StringBuilder();
for (String n : numbers)
sb.append(Double.parse(number);
double result = Double.parse(sb.toString());
return result;
}
Why is this bad?
double result = Double.parse(sb.toString());
imagine is a more complicated assignment or calls another function that does some other weird stuff?

Recruiters often tell you to use numbers to highlight your successes. For example, "I did Programming Task ABC and increased sales of widgets by 1,000%". I'm curious how many of us actually have had access to and/or kept track of those kinds of success metrics in our prior jobs. I find myself guessing and even just making up numbers that nobody's going to have even the slightest possibility of verifying.6

We have an unit test that tests the average of a sequence of numbers generated randomly using a gaussian distribution. Of course it fails from time to time, it's random! Failing to fail, would mean that the generator is not generating random numbers, therefore failure means success, but success does not mean failure.
Wait, why did we add this test in the first place? -

Okay so I'm new to C++ and my competition is either tomorrow or Thursday. And before I go into the comp I need a good random number generator but the problem is I can't get a good one . And when I run mine I either get the same number a few times in a row then when it changes it just increments a few until it hits 99 then restarts. And I only want it to generate different numbers everytime with a 1/99 chance to get the same number.2

In android 7.1, I've seen a lot of conflicting reports about crypto security.
If I do something like the following in the default android 7.1 browser...
var array = new Uint32Array(n);
window.crypto.getRandomValues(array);
How secure would the resulting numbers be overall? I'm asking because I've seen a lot of articles talking about it, but they never specifically mention the default 7.1 android *browser* and what or how it obtains secure random numbers. They only ever talk about the api, sdk, and developers working in java.4 -

I do not like it but I am forced to ask a tech question because my friend google has no idea how to solve this problem...
So, I have a pdf with a bunch of points with a number inside. I have to produce a list of numbers with X and Y coordinate of the point.
What I have tried: convert pdf to HTML and extract the position of divs / completely failed because a lot of points were distorted, mixed up, contained more numbers, etc, it's just not precise enough after conversion.

I'm at uni learning about floating point numbers and IEEE 754 and its so different to what I learnt at A-Level and it seems that using twos compliment floating point numbers is more efficient than storing numbers than IEEE 754 as IEEE 754 seems to use sign and magnitude. So why do we use IEEE 754?1

Find an error on line 69... start to giggle....
In dutch a "line" as in "error on line .." can be translated to "regel"
And in dutch "regel" can have two meanings.
Line and Rule.
Error on line 34.
Reading out loud in Dutch: "Error op regel 34"
translated to:
Error on rule 34. Launching out loud and thinking of the possibility.

Let's say I take a matrix of high entropy random numbers (call it matrix J), and encode a problem into those numbers (represented as some integers which in turn represent some operations and data).
And then I generate *another* high entropy random number matrix (call it matrix K). As I do this I measure the Pearson's correlation coefficient between J (before encoding the problem into it, call Jb), and K, and the correlation between J (after encoding, let's call it Ja) and K.
I stop at some predetermined satisfactory correlation level, let's say > 0.5 or < -0.5
I do this till Ja is highly correlated with some sample of K, and Jb's correlation with K is close to 0.
Would the random numbers in K then represent, in some way, the data/problem encoded in Ja? Or is it merely a correlation?
Keep in mind K has no direct connection to J, Ja, or Jb, we're only looking for a matrix of high entropy random numbers that indicated a correlation to J and its data.
I say "high entropy", it would be trivial to generate random numbers with a PRNG that are highly correlated simply by virtue of the algorithm that generated them.12 -

TrumpScript is one funny programming language that was formulated by four Rice University undergraduates. TrumpScript allows developers to operate with numbers that are bigger than one million. If programmers user numbers less than a million then it will generate a quote from Donald Trump as an error message: ”I’m really rich, Part of the beauty of me is I’m very rich.”1
