Search - "random numbers"
Was letting my five year old cousin play on my laptop today. She was writing numbers in notepad, and after typing '123', she erased them because she wanted to start over from 0 instead.
Later she started typing 1 and 0 repeatedly in random sequence.
She may be a robot. Either way, I sense a bright future ahead for her.2
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
Welcome back to practiseSafeHex's new life as a manager.
Episode 2: Why automate when you can spend all day doing it by hand
This is a particularly special episode for me, as these problems are taking up so much of my time with non-sensical bullshit, that i'm delayed with everything else. Some badly require tooling or new products. Some are just unnecessary processes or annoyances that should not need to be handled by another human. So lets jump right in, in no particular order:
- Jira ... nuff said? not quite because somehow some blue moon, planets aligning, act of god style set of circumstances lined up to allow this team to somehow make Jira worse. On one hand we have a gigantic Jira project containing 7 separate sub teams, a million different labels / epics and 4.2 million possible assignees, all making sure the loading page takes as long as possible to open. But the new country we've added support for in the app gets a separate project. So we have product, backend, mobile, design, management etc on one, and mobile-country2 on another. This delightfully means a lot of duplication and copy pasting from one to the other, for literally no reason what so ever.
- Everything on Jira is found through a label. Every time something happens, a new one is created. So I need to check for "iOS", "Android", "iOS-country2", "Android-country2", "mobile-<feature>", "mobile-<feature>-issues", "mobile-<feature>-prod-issues", "mobile-<feature>-existing-issues" and "<project>-July31" ... why July31? Because some fucking moron decided to do a round of testing, and tag all the issues with the current date (despite the fact Jira does that anyway), which somehow still gets used from time to time because nobody pays attention to what they are doing. This means creating and modifying filters on a daily basis ... after spending time trying to figure out what its not in the first one.
- One of my favourite morning rituals I like to call "Jira dumpster diving". This involves me removing all the filters and reading all the tickets. Why would I do such a thing? oh remember the 9000 labels I mentioned earlier? right well its very likely that they actually won't use any of them ... or the wrong ones ... or assign to the wrong person, so I have to go find them and fix them. If I don't, i'll get yelled at, because clearly it's my fault.
- Moving on from Jira. As some of you might have seen in your companies, if you use things like TestFlight, HockeyApp, AppCenter, BuddyBuild etc. that when you release a new app version for testing, each version comes with an automated change-log, listing ticket numbers addressed ...... yeah we don't do that. No we use this shitty service, which is effectively an FTP server and a webpage, that only allows you to host the new versions. Sending out those emails is all manual ... distribution groups?? ... whats that?
- Moving back to Jira. Can't even automate the changelog with a script, because I can't even make sense of the tickets, in order to translate that to a script.
- Moving on from Jira. Me and one of the remote testers play this great game I like to call "tag team ticketing". It's so much fun. Right heres how to play, you'll need a QA and a PM.
*QA creates a ticket, and puts nothing of any use inside it, and assigns to the PM.
*PM fires it back asking for clarification.
*QA adds in what he feels is clarification (hes wrong) and assigns it back to the PM.
*PM sends detailed instructions, with examples as to what is needed and assigns it back.
*QA adds 1 of the 3 things required and assigns it back.
*PM assigns it back saying the one thing added is from the wrong day, and reminds him about the other 2 items.
*QA adds some random piece of unrelated info to the ticket instead, forgetting about the 3 things and assigns it back.
and you just continue doing this for the whole dev / release cycle hahaha. Oh you guys have no idea how much fun it is, seriously give it a go, you'll thank me later ... or kill yourselves, each to their own.
- Moving back to Jira. I decided to take an action of creating a new project for my team (the mobile team) and set it up the way we want and just ignore everything going on around us. Use proper automation, and a kanban board. Maybe only give product a slack bot interface that won't allow them to create a ticket without what we need etc. Spent 25 minutes looking for the "create new project" button before finding the link which says I need to open a ticket with support and wait ... 5 ... fucking ... long ... painful ... unnecessary ... business days.
... Heres hoping my head continues to not have a bullet hole in it by then.
Id love to talk more, but those filters ain't gonna fix themselves. So we'll have to leave it here for today. Tune in again for another episode soon.
And remember to always practiseSafeHex16
I laughed at how in the movies hacking is portrayed as some person clicking a lot buttons really quickly in a very flashy UI. There's a picture of America and sometimes there's a 3d model rotating for no good reason or a bunch of random numbers floating across the screen. They use random hacking related terms like: backdoor, DDoS...etc in their sentences.
At least they did their research...17
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 lot28
The last year my school installed MagicBoards (whiteboard with beamer that responses to touch) in every class room and called itself "ready for the future of media". What they also got is A FUCKING LOW SPEC SERVER RUNNING DEBIAN 6 W/O ANY UPDATES SINCE 2010 WHICH IS DYING CONSTANTLY.
As I'm a nice person I asked the 65 y/o technician (who is also my physics teacher) whether I could help updating this piece of shit.
Teacher: "Naahh, we don't have root access to the server and also we'll get a new company maintaining our servers in two years. And even if we would have the root access, we can't give that to a student."
My head: "Two. Years. TWO YEARS?! ARE YOU FUCKING KIDDING ME YOU RETARDED PIECE OF SHIT?! YOU'RE TELLING ME YOU DON'T HAVE TO INSTALL UPDATES EVEN THOUGH YOU CREATE AN SSH USER FOR EVERY FUCKING STUDENT SO THEY CAN LOGIN USING THEIR BIRTH DATE?! DID YOU EVER HEAR ABOUT SECURITY VULNERABILITIES IN YOUR LITTLE MISERABLE LIFE OR SOUNDS 'CVE-2016-5195' LIKE RANDOM LETTERS AND NUMBERS TO YOU?! BECAUSE - FUNFACT - THERE ARE TEN STUDENTS WHO ARE IN THE SUDO GROUP IF YOU EVEN KNOW WHAT THAT IS!"
Me (because I want to keep my good grades): "Yes, that sounds alright."13
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?
Me: How many jobs need assignment?
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
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
Very long story ahead!
Yesterday in the evening a friend of mine (calling him F from now on) became the target of something new to me...
Apparently one can fake his phone number through some fishy ways and call people with that number. Someone (we think we might know who it was, the why is at the end) did this yesterday to F.
Here's the whole story:
We were just talking together on a TeamSpeak Server (a program to talk to others on the internet) when suddenly another friend said: "F, why did you just call me three times in a row?" That was the first thing that was a bit suspicious. After that, F got calls from random numbers (even Afghanistan, we are German), and they said something like "Have fun with the police coming to your house". Then there was silence. 10 minutes later his phone rang and there were a ton of pizza delivery services in his town that apparently got pizza orders from him. Then there was silence, again. Suddenly someone with a hidden number called him, a woman's voice said they were the police and if F doesn't stop calling the police there will be consequences. F then told her what was going on but I think she didn't really care. She then wanted to know where F lives, but I told him not to say that, because if it is the police they can find it out by themself and if it's not, they don't need to know that.
Now, a short break: There is some fake information going around about where F lives. I can't remember when we found out but the attacker thought he would actually live there. No idea what happened at that location...
Now back to the story:
Time went by, nothing really happened. Suddenly F shouted: "There are blue lights outside! The police is here!" He muted his microphone and (the following is what he told us what happened) went down to the door (remember, he is 16) and there were two police men. They were asking about why he called the police. F explained what we knew until then, about number spoofing and stuff... They sent a more technical person to him, he understood what F was trying to explain. The police men drove away and he came back to tell us what happened. (Now we get back to what I heared myself.) The mom came in, screamed something that I couldn't understand, and F went offline. We searched who the attacker could have been. And we are pretty sure we found him. That guy connected to our Minecraft server (that's where I know F from) with his real IP, and his main account, which made it easy to search. He also got a static IP which means it doesn't change. We also got some information that in the recent days this guy was talking about VoIP spoofing and such stuff. Another friend of mine, a bit older, found some proofs and I think he will go to the police.
That's it. Thanks for reading.8
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.😁12
Just heard at the coffee machine: "Well, does that mean I'm not allowed to use Trump's quotes to seed the random numbers generator?"1
There is a function for creating random numbers.
So with the same inputs , I must get the same output.
So it is somewhat predictable.
So it is not actually random!
Am I tight?33
This happened yesterday. It was a Friday and I didn't have much time to implement something that I was asked.
I was supposed to get the cpu temperature from a host device and send it to the server. Instead I just used random.randint(x,y) (python random function) with x,y linearly dependent on cpu utilisation (cpu utilisation is easy to get).
The ability to generate random numbers on fly has to be on of the coolest things that you can do. You can almost fake anything using them properly 😅8
Was just thinking of building a command line tool's to ease development of some of my games assets (Just packing them all together) and seeing as I want to use gamemaker studio 2 thought that my obsession with JSON would be perfect for use with it's ds_map functions so lets start understanding the backend of these functions to tie them with my CL tool...
Oh this might be helpful, easily save a data structure with decent encryption...
*Looks at saved output and starts noticing some patterns*
Hmm, this looks kinda familiar... Hmmm using UTF-8, always ends with =, seems to always have 8 random numbers at the start.. almost like padding... Wait... this is just base64!
Now yoyogames, I understand encryption can be hard but calling base64 'secure' is like me flopping my knob on the table and calling it a subtle flirt...6
We were working on a project with a scanner for employee id cards.
My coworkers plugged the receiver of that hand scanner into my pc and put it behind my desk while I was in the bathroom.
When I came back they started scanning random stuff without me noticing. Suddenly internet explorer opened itself ( my default browser was chrome), entered a weird string of letters and numbers into the search bar and hit the search button. I was shocked and didn't know what was going on and suddenly it did the same thing again. When I asked my coworkers for advice and help they kept a straight face and started discussing possible causes for that problem with me. It took me a while to see the receiver plugged in and hidden behind my table.
Today I had to write a unit test to test a method that internally used a random number generator...
My test was literally just assertNotNull...4
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
For fucks sakes people.
Ocamms razor is a very helpful problem solving tool.
HOWEVER IT ISN'T AN EXCUSE FOR NOT HAVING A PROPER ARCHITECTURE, OR SHITTING ON IT, HAMMERING RANDOM IFs EVERYWHERE, USING A METRIC SHITTON OF MAGIC NUMBERS HAVING A LOT OF REDUNDANT CODE AND ZERO DOCUMENTATION!
YOU CAN'T DO THAT "just because it's the simplest solution"! NO. THAT'S JUST UNACCEPTABLE. YOU ARE A HORRIBLE PERSON.
GO TO HELL YOU STUPID SCUM WITH YOUR PILE OF CHOPSTICKS BURNING THAT IS YOUR CODEBASE!
But before that, would you mind touching these two wires definitely not connected to the mains?3
As an iPhone user, who generally appreciates an iPhone over google spyware, I have to say Live Photo’s are CANCER and are KILLING ME SLOWLY.
They take up a ton of space, are basically movies (wrong format for high quality images) when you text too many of them it creates them as an iCloud attachment (kill me) and sends the link to somebody, when you connect your phone to your computer the photos app for some certain Live Photo’s does one of the following 4. at random:
1. Fail to import the photo and give an error message
2. Import the photo but it shows up as a video in your library
3. Import the photo and it shows up as a Live Photo as it should
4. Import the photo and it does not show up at all in your library but no error
But regardless of which of these happens, the same photo will show up as a new photo to import the next time you connect your phone to the computer. So you end up with different numbers of different types of duplicates of only certain Live Photo’s on your phone, but not all of them!
These sorts of problems frustrate me because they are mundane and waste my time, when I could be focusing on other things like hacking on compilers or smt solvers, so I said “fuck it, I’m going to delete all the Live Photo’s from my phone.” It was only about 100, and of those 100 about 30 were persistently problematic.
Well, after I did that 18 of them kept showing up but as black squares in photos but weren’t on my phone! And of course it failed to import them because they were gone.
after rebooting my phone twice and waiting a day and rebooting it again this problem has gone away and i will never take or share a Live Photo again as long as I live. If you’re going to make something new, you have to remember to actually write software that works. Pls, kthx. Otherwise you will cause Frodo to work on things that are not smt solvers or compilers and this will make Frodo very no bueno.8
I remember the first time our class coded a simple program in C. The objective was to input two random numbers, check which one is larger, and output it on the screen.
After class, I asked one of my classmates if he finds the test easy. My classmate replied that it was so easy he got bored. Then when I asked him to show me his code, this was what I saw:
int a, b;
printf("Enter smaller number: ");
printf("Enter larger number: ");
printf("Larger number: %i\n", b);1
Python: RandInt(0, 2) generates a random value between 0 and 2. Range(0, 2) generates a list of all numbers between 0 and 1. Boy, there's some consistent syntax.
I just had such a forfilling moment.
Normally, i often (force myself) go to bed at night, after i worked on a project of mine, with these thought saying "oh man i wanted to get that feature done today" or "i want to finish this and that part of my code".I am sure everyone of you knows the feeling, when your brain communicates that you are just not done for today.
Today it was different. I got a project of mine working in it's first state, where i put much heart, love and time in.Just a few minutes before i finished for today i got my server responding the expected numbers(some kind of pin-code). It's a very easy system: Someone(at the time only me and my debug mode :3) on a android phone request a verification which is checked and processed by the server. The server creates a random six-digit number, returns it encoded to the client and sends an email to the user, which currently sends it in plain text(shame on me).
Yeah, the user enters the number and voilà
And of course, all the Pincodes can only be used once.
I got to bed with this feeling of luck and succes.
I hope tomorrow is going to be a productive day!
I am so lucky right now.
Have a good day everyone!
This is another high school story. mostly because i’m in high school.
like most schools we have horrible forced passwords. Our school recently purchased microsoft 365. which means we all use outlook for our emails. the logins for our district follow the sand format.
s + first five of last name (x’s for missing letters) + first letter of your first name + the last three of your student id.
so for example Sean Peterson 456705 would be speters705. since we have outlook we can look up a persons name and get their email which gives you the last three of their password. All passwords start with a 4 and most are followed by a five so you pretty much can get 5 out of the 6 numbers in their password.
so to mess with my friends i signed into all of their accounts and messed with their emails so they thought they were getting random emails. and then i made word documents on all of their accounts and just pretty much messed with all of their school stuff.
so that’s my “hacking” story. my district doesn’t allow you to change your password so i’m pretty much stuck. pls help.4
Professor: writes a loop to sum up first five numbers and asks the output.
Other random student: 15
Prof praises him.
He runs the code.
Output: 500 ( internal server error)
(He had a missing semicolon) 😅6
During my first semester of CS we were mostly using MatLab for basal scripting - assigning variables, learning about scope, that type of thing. I was excited to start learning programming but wanted to actually make something rather than reversing arrays and incrementing counters for weeks.
I discovered the image() function which takes a float matrix and displays it as an image. I generated my arrays of random numbers and made a simple nested loop where I iterated over each element, averaging it with its neighbours, and - it worked on the first run! I made a freaking noise and blur filter!
That rush of planning it out, making it, and seeing it work I think is my main drive in coding. All the hours of undefined-but-they-are-tho import paths and mystery segfaults are worth it once there is that moment of "it lives!".
In an IT management class, the professor wanted us to estimate the operation costs for a small IT company, breaking them down by service offered. I remember creating a markdown file, multiple times executing the line `echo $RANDOM >> estimations.md`. We rounded the numbers slightly, pimped the document a bit and submitted a nice PDF. When we had to present our work, the professor asked us how we had proceeded to calculate those results. We told him a story about an Excel file we worked on, but did not submit, because we thought he'd be interested in the end result and not care about those details. He asked us to submit that Excel calculation, because he wanted to comprehend our method. So we got together, created an Excel sheet, copied our "estimations" into column C and called it "service cost". For column B, we used the same "cost per man hour" value (scientifically estimated using the RAND() function) for every row. Finally, we divided the "service cost" by the "cost per man hour" for every row, put the result in column A and called it "effort (in man hours)". The professor, being able to "reproduce" our estimation, accepted our solution.2
#just Bluetooth headphones things
When you're sitting on crowded public transportation and can't hear anything unless your phone is closer to your headphones than anyone else's, i.e. unless it's close as shit to your face 😍😍😍
When you want to listen to music for longer than 2 hours or several times during your workday but can't because the BT headphones last 2-3 hours 😍😍😍
When the left and right side don't pair with each other but you can pair with each individually 😍😍😍
When half of the button presses and user interactions aren't documented and there's no way to forget a device 😍😍😍
When you try to connect a new device to them in a public area and just see a dozen random serial numbers, so you have to wait and hope they get resolved to the headphone brand name 😍😍😍
When Satan takes your soul and the Bluetooth connection drops in hell 😍😍😍
When the music quality is lower and can experience static and maybe even skip in between 😍😍😍
When the bus hits a road bump, it falls out of your ear, and rolls halfway down the bus 😍😍😍
When it takes a long time to find them because they tiny af, and just as long to find the charging cable 😍😍😍
When manufacturers cannot agree on a standard volume sync system and so you have to check the volume and adjust every time you connect and disconnect your headphones 😍😍😍
Can we please just stop making everything Bluetooth?
Someone who just wanted to listen to a 2 minute billie eilish song but found it easier to sing in his head13
Wanted to test out random number generation in different distributions. So did it using HTML/JS using google charts APIs, just to find out after sometime that R does what i did by default..2
Got a phone call from a scammer claiming to be my Cell Phone Provider saying “Congratulations! You just recieved unlimited calls and messages for a year, now to win this please give the 4 digit pins given to you” then I recieved a 4 digit pin and warning label not to give this message to anyone else. I then noticed that this was a scammer, i got his probably fake number and I tried to mess with him by giving random codes, he then noticed that the numbers were fake in the 5 try.
I truly feel bad for this idiot and just call him a scammer and end the call...1
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.4
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
When I close my eyes I see identical objects in array, forming random numbers.
Last time it was a 7.
Anyways, gotta sleep.1
nothing new, just another rant about php...
php, PHP, Php, whatever is written, wherever is piled, I hate this thing, in every stack.
stuff that works only according how php itself is compiled, globals superglobals and turbo-globals everywhere, == is not transitive, comparisons are non-deterministic, ?: is freaking left associative, utility functions that returns sometimes -1, sometimes null, sometimes are void, each with different style of usage and naming, lowercase/under_score/camelCase/PascalCase, numbers are 32bit on 32bit cpus and 64bit on 64bit cpus, a ton of silent failing stuff that doesn't warn you, references are actually aliases, nothing has a determined type except references, abuse of mega-global static vars and funcs, you can cast to int in a language where int doesn't even exists, 25236 ways to import/require/include for every different subcase, @ operator, :: parsed to T_PAAMAYIM_NEKUDOTAYIM for no reason in stack traces, you don't know who can throw stuff, fatal errors are sometimes catchable according to nobody knows, closed-over vars are passed as functions unless you use &, functions calls that don't match args signature don't fail, classes are not object and you can refer them only by string name, builtin underlying types cannot be wrapped, subclasses can't override parents' private methods, no overload for equality or ordering, -1 is a valid index for array and doesn't fail, funcs are not data nor objects when clojures instead are objects, there's no way to distinguish between a random string and a function 'reference', php.ini, documentation with comments and flame wars on the side, becomes case sensitive/insensitive according to the filesystem when line break instead is determined according to php.ini, it's freaking sloooooow...
enough. i'm tired of this crap.
it's almost weekend! 🍻2
Want to see hair falling of a developer's head?
Just watch him trying to get some millions of fast and good random numbers.7
So let's do a "community building" exercise.
What was your biggest tech pet peeve?
I hate it when people (especially teachers) give us a printout with a link to a website (like a good docs link) without shorting it.
I mean, we have to type out that 100+ character string of random numbers and letters. Then you make a mistake and have to retype it. (I.k,. First world problems)
Let's here yours. It can be about employers, teachers, or anyone else you can think of.3
Russians Engineer a Brilliant Slot Machine Cheat
...But as the “pseudo” in the name suggests, the numbers aren’t truly random. Because human beings create them using coded instructions, PRNGs can’t help but be a bit deterministic. (A true random number generator must be rooted in a phenomenon that is not manmade, such as radioactive decay.) PRNGs take an initial number, known as a seed, and then mash it together with various hidden and shifting inputs—the time from a machine’s internal clock, for example—in order to produce a result that appears impossible to forecast. But if hackers can identify the various ingredients in that mathematical stew, they can potentially predict a PRNG’s output. That process of reverse engineering becomes much easier, of course, when a hacker has physical access to a slot machine’s innards...
When is devrant going to fix the notification counter? I've never seen it work properly. The numbers spins through several seemingly random numbers and end on a wrong number 😕1
