how to improve UX

Now, I work at a hosting company in the UK, as a linux support engineer. I've seen many cases where a number of clients ran one of the following:

rm -rf / something
rm -rf /var/cache (attempt to magento)
chmod 777 /var
chown -R user:user /*

Half the time, they're like "Hey guys, I dun did fuck up, please help!". The other half of the time, they piss me off. Here's a number of responses that really grinds my gears:

"Such a harmful command should really prompt for input before running" -- From the buy you "forced" a recursive rm command, which mutes such a feature.

Client: "I did no such thing"
Me: "I've seen the command history, and at the time the command was run, you were the only person logged in"
Client: "You're mistaken, You're reading the information wrong"
Me: "I assure you, I'm not, I know what I'm looking at"
Client: "Well you're a shit engineer"
Me (thought): "Says the fucker who doesn't know how to linux"

I like people who own up to fuck ups. But the ones that don't, are just making their lives harder, since we have all the evidence in front of us.

Most of these people are the developers, and in some cases, the sysadmins...

Our html:

<input type="number"/>

Accepts only numbers, so far so good. Until QA files a bug:

"Numeric input accepts the letter 'e' "

Apparently 'e' is a valid because you can input something like '1e3' which fucking means '1000' !

Our team tried to argue with the QA that 'e' is valid because it simply means exponent but they argue a normal user would not know what an exponent means because they are not "mathematically inclined"

Part of me agrees with what the QA argues but then I think an average user who could use a fucking laptop or mobile will most certainly know what an exponent is.

My Interview question was simple, just :
Create an algorithm using **JAVA** accepting row input which output corresponding diagram :

1.
*
**
***
****

2.
*
**
***
****

3.
54321
4321
321
21
1

I said, well this going to be easy. Turns out they give me one sheet of FUCKING PAPER. ARE YOU OUT OF YOUR MIND? THIS IS JAVA NOT A FUCKING PYTHON.

But in the end i complete the test except i don't write the :

public stupid static motherfucking main(String[] dick){}

in every single number. Got Zero in the test. Didn't get the job.

I win.

And BAM. Wrote a quick'n dirty little php script which works with loads of shell_exec calls to block all ip addresses belonging to an ASN number.

For example: If I get Facebook's ASN number and use it as parameter for this script with a custom name (for the iptables chain), the script creates a chain called the custom name, adds all ip addresses/ranges it got from the whois lookup (on the ASN number) with DROP to iptables and then it adds that chain to the INPUT and OUTPUT chains.

I've done some tests and can indeed genuinely not reach Facebook at all anymore, Microsoft is entirely blocked out as well already 💜

#define Minion (A junior from my college)

Minion : Hey, can you suggest me from some good project for my final year.

Me : Sure , which "programming language" do you know?

Minion : Well i am good at HTML.

Me(triggered);
Me : Ya sure , make a "program" using HTML only that takes input from a user and prints that nth prime number.

Minion : 😱😱😱😱

Beware, this is gonna be a long one.

Today, in university, our professor wanted us to do an algorithm where a number was given in input, and we had to see if that number was, as she put it, "triangular".
For example:
3 is triangular because it's 1+2.
6 is triangular because it's 1+2+3.
10 is triangular because it's 1+2+3+4.
And so on.

While she was explaining this, I was programming it on my phone (because I didn't bring a PC there).
In about 10 minutes I completed it.

This student who was beside me, which I didn't know until today (I'm still in my first year here), saw me programming it, and when I finished it, he looked at it and said: "It takes too much time, like this."
So he spent another like 5-10 minutes """fixing""" it, and then showed it to me: "Here, now it's better."
Do you want to know what he did?
The only thing he did was putting a for cycle instead of my while cycle.
And he didn't even do it properly!
He put an else statement inside the brackets of an if, and some variables weren't correct.
You call that making a program more efficient? Deficient is more like it.

Also, like 5-10 minutes after I did it on my phone, on my own, I looked at the prof's desk: a guy (who apparently is "the best") wrote his algorithm on the blackboard, and the whole fucking class applauded.

Later, I saw on our Whatsapp group that someone sent a photo of him writing on the blackboard, with the caption "The student surpasses the teacher." Others agreed.
I replied with: "For the record, I did this algorithm in 10 minutes."
An asshole replied: "You'll never be superior to the master"

Fuck off. -.-"
...I'll show them.

A few weeks ago I stepped onto the grounds of lovely Canada. Back then - coming from Europe - I was surprised. Free WiFi everywhere without all the bells and whistles of creating an account and such.

Well ... at least I thought so ...

Today I went to a location where they actually charge you for their wireless services - fair enough the coverage area is pretty huge - and provide you with an access coupon. All good my optimistic me told me but once the login page loaded...

There are a lot of things about UX I could rant about but let's put that aside. The coupon came from the office where they KNEW all your contact details but it required you to create an account with all of them again to redeem the coupon.

Not only that but it asked for things like the phone number - obviously asking for a Canadian landline number since hell who uses mobiles anyway with numbers longer than ten characters?! - and even though it had a nice country selection it kept the states field there even when selecting a country that doesn't have states ...
Oh, and on a regular phone screen (which would be the target user for WiFi on a campground I suppose) the input fields for state and zip were occluded by the margins of the input rendering the content invisible.

And if that weren't enough after creating your account they made you watch an ad as if the personal data and the 4$ you paid them wasn't enough for the lousy 400 KB/s you get for 24h ...

Gets better though! After creating the account they display your password to make sure you remembered it ... over a non-secured WiFi network ... and send you an email afterward ... password via unencrypted mail via an unencrypted WIRELESS connection ... not that it protects anything that would matter anyways you can just snoop the MAC of your neighbor and get in that way or for that sake get their password but oh well ...

Gosh, sometimes I just feel the urgent need to find the ones responsible and tell them to GTFO of the IT world ...

Is it just me feeling like this about crappy UI/UX design? Always wondering...

Let's see the coder in you.
If I give input: 1 output: 2
If I give input: 2 output:1
Only these two test cases needed.
You should not use control structures such as if,else,for,while,switch etc. (The answer is simple) (Don't cheat)

int number;
cin>>number; //get number
cout<<??????; //Your code

Oh man. Mine are the REASON why people dislike PHP.

Biggest Concern: Intranet application for 3 staff members that allows them to set the admin data for an application that our userbase utilizes. Everything was fucking horrible, 300+ php files of spaghetti that did not escape user input, did not handle proper redirects, bad algo big O shit and then some. My pain point? I was testing some functionality when upon clicking 3 random check boxes you would get an error message that reads something like this "hi <SENSITIVE USERNAME DATA> you are attempting to use <SERVER IP ADDRESS> using <PASSWORD> but something went wrong! Call <OLD DEVELOPER's PHONE NUMBER> to provide him this <ERROR CODE>"

I panicked, closed that shit and rewrote it in an afternoon, that fucking retard had a tendency to use over 400 files of php for the simplest of fucking things.

Another one, that still baffles me and the other dev (an employee that has been there since the dawn of time) we have this massive application that we just can't rewrite due to time constraints. there is one file with (shit you not) a php include function that when you reach the file it is including it is just......a php closing tag. Removing it breaks down the application. This one is over 6000 files (I know) and we cannot understand what in the love of Lerdorf and baby Torvalds is happening.

From a previous job we had this massive in-house Javascript "framework" for ajax shit that for whatever reason unknown to me had a bunch of function and object names prefixed with "hotDog<rest of the function name>", this was used by two applications. One still in classic ASP and the other in php version 4.something

Legacy apps written in Apache Velocity, which in itself is not that bad, but I, even as a PHP developer, do not EVER mix views with logic. I like my shit separated AF thank you very much.

A large mobile application that interfaced with fucking everything via webviews. Shit was absolutley fucking disgusting, and I felt we were cheating our users.

A rails app with 1000 controller methods.

An express app with 1000 router methods with callbacks instead of async await even though async await was already a thing.

ultraFuckingLarge Delphi project with really no consideration for best practices. I, to this day enjoy Object Pascal, but the way in which people do delphi can scare me.

ASP.NET Application in wich there seemed to be a large portion of bolted in self made ioc framework from the lead dev, absolute shitfest, homie refused to use an actual ioc framework for it, they did pay the price after I left.

My own projects when I have to maintain them.

I'll use this topic to segue into a related (lonely) story befitting my mood these past weeks.

This is entire story going to sound egotistical, especially this next part, but it's really not. (At least I don't think so?)

As I'm almost entirely self-taught, having another dev giving me good advice would have been nice. I've only known / worked with a few people who were better devs than I, and rarely ever received good advice from them.

One of those better devs was my first computer science teacher. Looking back, he was pretty average, but he held us to high standards and gave good advice. The two that really stuck with me were: 1) "save every time you've done something you don't want to redo," and 2) "printf is your best debugging friend; add it everywhere there's something you want to watch." Probably the best and most helpful advice I've ever received 😊

I've seen other people here posting advice like "never hardcode" or "modularity keeps your code clean" -- I had to discover these pretty simple concepts entirely on my own. School (and later college) were filled with terrible teachers and worse students, and so were almost entirely useless for learning anything new.

The only decent dev I knew had brilliant ideas (genetic algorithms, sandboxing, ...) before they were widely used, but could rarely implement them well because he was generally an idiot. (Idiot sevant, I think? Definitely the idiot part.) I couldn't stand him. Completely bypassing a ridiculously long story, I helped him on a project to build his own OS from scratch; we made very impressive progress, even to this day. Custom bootloader, hardware interfacing, memory management, (semi) sandboxed processes, gui, example programs ...; we were in highschool. I'm still surprised and impressed with what we accomplished.

But besides him, almost every other dev I met was mediocre. Even outside of school, I went so many years without having another competent dev to work with. I went through various jobs helping other dev(s) on their projects (or rewriting them), learning new languages/frameworks almost every time: php, pascal, perl, zend, js, vb, rails, node, .... I learned new concepts occasionally (which was wonderful) but overall it was just tedious and never paid well because I was too young to be taken seriously (and female, further exacerbating it). On the bright side, it didn't dwindle my love for coding, and I usually spent my evenings playing with projects of my own.

The second dev (and one one of the best I've ever met) went by Novo. His approach to a game engine reminded me of General Relativity: Everything was modular, had a rich inheritance tree, and could receive user input at any point along said tree. A user could attach their view/control to any object. (Computer control methods could be attached in this way as well.) UI would obviously change depending on how the user could interact and the number of objects; admins could view/monitor any of these. Almost every object / class of object could talk to almost everything else. It was beautiful. I learned so much from his designs. (Honestly, I don't remember the code at all, and that saddens me.) There were other things, too, but that one amazed me the most.

I havent met anyone like him ever again.

Anyway, I don't know if I can really answer this week's question. I definitely received some good advice while initially learning, but past that it's all been through discovering things on my own.

It's been lonely. ☹

(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.

Tl;Dr - It started as an escape, carried on as fun, then as a way to be lazy, and finally as a way of life. Coding has defined and shaped my entire life from the age of nine.

When I was nine I was playing a game on my ZX spectrum and accidentally knocked the keyboard as I reached over to adjust my TV. Incredibly parts of it actually made a little sense to me and got my curiosity. I spent hours reading through that code, afraid to turn the Spectrum off in case I couldn't get back to it. Weeks later I got hold of a book of example code to copy out to do various things like making patterns on the screen. I was amazed by it. You told it what to do, and it did it! (don't you miss the days when coding worked like that?) I was bitten by the coding bug (excuse the pun) and I'd got it bad! I spent many late nights on that thing, escaping from a difficult home life. People (especially adults) were confusing, and in my experience unpredictable. When you did things wrong they shouted at you and threatened to take you away, or ignored you completely. Code never did that. If you did something wrong, it quietly let you know and often told you exactly what was wrong. It wasn't because of shifting expectations or a change of mood or anything like that. It was just clean logic, simple cause and effect.

I get my first computer a year later: an IBM XT that had been discarded by a company and was fitted with a key on the side to turn it on. With the impressive noise it made it really was like starting an engine. Whole most kids would have played with the games, I spent my time playing with batch scripts and writing very simple text adventures. And discovering what "format c:" does. With some abuse and threatened violence I managed to get windows running on it. Windows 2.1 I think it was.

At 12 I got a Gateway 75 running Windows 95. Over the next few years I do covered many amazing games: ROTT, Doom, Hexen, and so on. Aside from the games themselves, I was fascinated by the way computers could be linked together to play together (this was still early days for the Web and computers networked in a home was very unusual). I also got into making levels for Doom, Heretic, and years later Duke Nukem 3D (pretty sure it was heretic; all I remember is the nightmare of trying to write levels entirely by code!). I enjoyed re-scripting some of the weapons and monsters to behave differently. About this time I also got into HTML (I still call this coding, but not programming), C, and java. I had trouble with C as none of the examples and tutorial code seemed to run properly under a Windows environment. Similar for my very short stint with assembly. At some point I got a TI-83 programmable calculator and started rewriting my old batch script games on it, including one "Gangster Lord" game that had the same mechanics as a lot of the Facebook games that appeared later (do things, earn money, spend money to buy stuff to do more things). Worried about upcoming exams, I also made a number of maths helper apps, including a quadratic equation solver that gave the steps, and a fake calculator reset to smuggle them into my exams. When the day came I panicked and did a proper reset for fear of being caught.

At 18 I was convinced I was going to be a professional coder as I started a degree in Computer Science. Three months later I dropped out after a bunch of lectures teaching what input and output devices were and realising we were only going to be taught Java and no C++. I started a job on the call centre of a big company, but was frustrated with many of the boring and repetitive tasks we had to do. So I put my previous knowledge to use, and quickly learned VBA to automate tasks. It wasn't long before I ended up promoted to Business Analyst where I worked on a great team building small systems in Office, SAS, and a few other tools.

I decided to retrain in psychology, so left the job I was in and started another degree. During my work and placements my skills came in use a number of times to simplify and automate tasks. I finished my degree, then took a job as a teaching assistant while I worked out what I wanted to do next and how to pay for it. Three years later I've ended up IT technican at the school, responsible for the website, teaching a number of Computing lessons each week, and unofficial co-coordinator for Computing as a subject. I also run a team of ten year old Digital Leaders who I am training in online safety and as technical experts; I am hoping to inspire them to a future in coding. In September I'll be starting teacher training with a view to becoming a Computing specialist teacher. Oh, and I'm currently doing a course in Android Development in my free time.

And this all started with an accidental knock on the keyboard of a ZX Spectrum.

I was pressued to shift the blame.

We received an angry email from a customer that some of their data had disappeared. The boss assigns me to this task. This feature is relatively new and we've found some bugs in the past in here. I go through request logs, search the database, run some diagnostics, etc. for about 5 hours and I cannot find the problem. I focus on the bugs that we've had before but they don't seem to be the problem.

I tell the boss "sorry but I checked XYZ and I can't find the problem. I'm out of ideas." But the boss wanted answers by the end of the day. They did not want to admit to the client that we couldn't figure out what's wrong.

By now I was more pressured to find an answer, find something or someone to blame it on, not exactly to find the real solution. So I made up some BS:

"Sometimes, in HTML forms, the number inputs allow you to change the number by scrolling. We have some long forms where the user has to scroll. Perhaps the focus remained on the number input, so when they scrolled down they accidentally changed the number they meant to input."

The boss was happy with that. We explained this to the customer, and there's now a ticket to change type="number" to type="text" in our HTML forms and to validate it in th backend.

A week later another customer shows us a different error. This one is more clear because it had a stack trace, but I realise that this error is what caused our last error. It was pretty obscure, mind you, the unit tests didn't detect it.

I didn't tell the boss that they were connected tho.

With two angry clients in two weeks, I finally convinced the boss to give us more time to write more unit tests with full coverage.

So, I'm a Portuguese dude. I have my OS's in English language and Portuguese keyboard. Today, I spent 30 min raging at my computer because I couldn't login. I tried like all my 865725428 passwords (fake number, in case u don't get it) and still couldn't access it. Then I fucking looked and remembered Windows is an asshole and changed my keyboard input to English, so all my symbols were changed. Fuck you Windows, Linux never did this to me. Y the fuck would u? Do u like to fucking make me waste my precious time? Go and fuck yourself with a 35'' CAT-5E cable you prick.

Well on my last full-time job, that ware using cookies for authentication (not something new, eh?). The thing is, you see, the cookies had the 'accountId' which if you change to another number, kaboom you're that account, oh but that was not all, there was an option to mark the account type in there 'accountType', which was kind of obvious in VLE (virtual learning environment), 'Teacher', 'Student', 'Manager' put what of those values and boom you are that role for the session

Thing was open of SQL injection from the login form, from said cookies and form every part you can pass input to it, when I raised the question to my TL he said 'no one is going to know about thatt, I don't see what is the problem', then escalated to higher management 'oh well speak to *tl_guy*'

Oh and bonus points for it being written in ASP CLASSIC in 2014+ (I was supposed to rewrite, but ended up patching ASP code and writing components in PHP)

In 2015-2016, in a private college, charging kind-of big money per year

This.

Not the worst but almost all of us (including me) handle strings like fucking morons.

If the input doesn't need to be an exact match we use a explicit comparison operator, when the input should explicitly match we do a loose comparison operator.

I'll format the crap out of a number, convert it, validate decimal places, check for float rounding hell, give it a absolute value and return it correctly formatted for the users locale but half the time I forget to trim their input. 🤦‍♂

Like I said - just a tad fucking moronic isn't it?

our university results are out
the webpage to check the results has only 3 input fields
roll number
date of birth
captcha
after checking the source code turnsout it doesn't need the date of birth and the most FUCKEDUP part is the captcha it uses is generated using javascript on the client side and literary checked using string1 == string2
I captured the post request its sending..
it only sends the roll number with some headers to the url
I wrote a quick python script to emulate the post request and got back the results of my entire college
note - the university I'm referring to has literally more than hundred thousand students under it, each and every student uses that interface to get his results

I've assembled enough computing power from the trash. Now I can start to build my own personal 'cloud'. Fuck I hate that word.
But I have a bunch of i7s, and i5s on hand, in towers. Next is just to network them, and setup some software to receive commands.

So far I've looked at Ray, and Dispy for distributed computation. If theres others that any of you are aware of, let me know. If you're familiar with any of these and know which one is the easier approach to get started with, I'd appreciate your input.

The goal is to get all these machines up and running, a cloud thats as dirt cheap as possible, and then train it on sequence prediction of the hidden variables derived from semiprimes. Right now the set is unretrievable, but theres a lot of heavily correlated known variables and so I'm hoping the network can derive better and more accurate insights than I can in a pinch.
Because any given semiprime has numerous (hundreds of known) identities which immediately yield both of its factors if say a certain constant or quotient is known (it isn't), knowing any *one* of them and the correct input, is equivalent to knowing the factors of p.

So I can set each machine to train and attempt to predict the unknown sequence for each particular identity.

Once the machines are setup and I've figured out which distributed library to use, the next step is to setup Keras, andtrain the model using say, all the semiprimes under one to ten million.

I'm also working on a new way of measuring information: autoregressive entropy. The idea is that the prevalence of small numbers when searching for patterns in sequences is largely ephemeral (theres no long term pattern) and AE allows us to put a number on the density of these patterns in a partial sequence, but its only an idea at the moment and I'm not sure what use it has.

Heres hoping the sequence prediction approach works.

Writing a brainfuck interpreter is a lot fun: Mine does recursion within loops. I also added functions: strings, you can cheat. Stackdump(!), Exit script(*) , go to first cell (^), go to last cell(?), nulling cell (0) It parses this for example: "retoor" ^[.>]. It will dump string retoor. Explanation: the string moves ptr to sixth place. ^ will reset pointer to first. [] is a loop that executes as long there's data in current cell. The "." prints char of current cell (Number if not alpha etc). ">" moves a cell to right. [.>] will thus print until it moved to an empty cell. To move to first, I could've also used my repeater function by adding times to repeat after command: <6 moves six places to left. .>.>.>.>.>.> is also a way to print six chars. +[,.] works as the Linux program "cat". , is one char keyboard input.

Thanks for listening to my tedtalk

When scammers want to follow GDPR regulations - the worst SCAM ever 🤦‍♂️

Long story:
I have just received a SMS message, informing me that my phone number is in several marketing databases. It also had a link to the website called stop-sms.pl, where you're supposed to be able to unsubscribe from those lists. At this moment I felt a little bit confused - the SMS seemed suspicious, but on the other hand who doesn't want to get rid of all this SMS crap. So I carefully followed the link to see the website with a form to fill with personal data - phone number included 😆 If that is not enough to realize that this is just a lame scam website, just below the input where you enter the phone number there are Terms and Conditions where it directly states that: "By filling the form you agree that your personal data (name, email, phone number) will be used for marketing purposes." - WTF?!

Who the f... gets fooled by such crap?! 😂😂😂

When i started my work I encoubtered this db(one of 4): more than 20 tables, some with 200 columns literally... EVERYTHING is a varchar 😓.

I'm slowly designing some normalized tables with real fk on new features and projects and people are like: how the fuck did you implement this feature so fast? the other guy spent 3 months designing this form (and I'm just speechless):

The form was some sort of crazyness shit passing input names as "name-of-property" and a file only to check if(name="string") then store a number value to an array and save it as a "number" (actually varchar) on the db. literally more than 50 if statements to do this.

Everything on a single table that made no sense at all.

Just wtf... At least my boss let me start if from scratch cause he we were always having panick attacks every time he needed to do something with it. 😂😂

UX quiz:
a) trim whitespace characters from credit card or bank account input
b) refuse transaction, show error message: "no spaces are allowed in the card number"

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: ");
scanf("%i", &a);
printf("Enter larger number: ");
scanf("%i", &b);
printf("Larger number: %i\n", b);

A few weeks ago, I was kept up until the wee hours of the morning trying to figure out how in the hell the Monty Hall problem works. After finally getting it (I'm slow, okay?), I decided to write a program to run simulations of it.

First incarnation of program took user input. User enters what door they choose (1, 2, or 3), then is told what door Monty opens, then given the decision of staying with the door they originally chose or switching, then informed how that worked out for them.

Second incarnation of program ran on a loop. At the start of each loop, a random door is picked for the user guess. Then the door Monty opens is calculated from the remaining doors (excludes user guess and prize door). Then user switches doors (choosing the door that was not their original door or the door Monty opened). At the end of each loop, if the door they switched to was the prize door, it would increment a win counter, else increment a loss counter. After running the loop 1000000000 times, it printed to console `You always switched doors, resulting in ${wins} wins and ${losses} losses`.

THEN I decided to write a variation to run a while loop on the outside of the loop to increase the number of total doors until the point where the decision to switch doors hurt more often than it helped. At this point, I decided to incorporate file I/O and write to a file rather than a console. And that was neat!

And then I decided it would be cool to go back to the three door variation, printing on each loop the original door, the door Monty opened, the door that was switched too, the result of the switch (win or lose) and what the prize door was.

But for the life of me, I couldn't seem to get the file to write properly. It would, like, always crash my terminal. I tried open + append, I tried append. I tried createWriteStream. Still just failure.

And then I changed it to an appendFileSync and happened to look at one of the files that I was writing to. "Huh, over a gig seems a lot."

"Well, how much are you writing each loop? Did you forget to keep in mind how many bytes that would be?"

TLDR: If you're going to write a program that's going to write data to a file on a loop, you might want to figure out how much it's going to end up writing .... before trying to run it. And running a loop 1000000000 times may be a little excessive.

*face palm*

Holy duck, I lost two days on a convolutional autoencoder splitted in two separate neural networks to encode and decode separately, it reconstruction had some strange behaviours. I was giving as input an image and then saving the encoded compressed representation in a new image, in this way I could decode it with the decoder whenever I want saving space.
How much retarded am I?
The internal layer's weights hadn't constraints so in learning phase the convolutional filters can contain any number, positive > 255 or even negative and I cannot save it in a new image as they are so they were clipped automatically between 0 and 255 with an huge information loss.
It's so frustrating when you rewrite the code in any possible way, you obtain the same wrong result and then you realize that was a borderline behaviour of a third part library.

What kind of seizure of insanity led the devs of Python to believe that static, mutable default parameters could be a good idea? You can literally share whole arrays between multiple calls of the same function with the same input, and the number of cases where a sane person would intentionally want to do that is FUCKING ZERO.

I got a median-pay front-end job through a contractor (after a contract from hell...but yeah I didn't learn...) and I'm getting zero assignments after a month and nobody seems to know what my role is.

I'm one month in, and every week I have to email my boss to remind her to sign my paycheck, which is stressful because I'm charging for my time because my assignments are like "Research this" or "look at this Wordpress theme or brand guide". The team never communicates but once a week, and I'm beginning to believe that I'm not a good fit for the team because they are impossible to get a hold of and the sysadmin won't give me access to anything even when I CC my boss. (I don't want to grief this guy...) Despite this, I've been told privately by higher-ups on a few occasions that they plan to hire me full time by November...

My SO thinks that the reason people are so dodgy toward me is because they literally do nothing and I'm breaking the flow of that by asking for things. I'm used to agency output, which can be toxic and where everything is 'due yesterday', and I'm watching this team work on assignments ten times slower than normal. ("You want to change a phone number on a website footer? You'll get it next week...maybe." I can't step on toes because I don't have access...) I'm perfectly fine with having to wear several hats at a low-stress job, but I can't even get my first assignment and I'm still being asked who I am in weekly meetings, or asked things like, "Would you even be willing to relocate here?" (I actually live DOWN THE STREET FROM THE OFFICE!! WHY DO I HAVE TO BE REMOTE? Why am I being asked this question?) It feels like my boss impulse hired me, with zero input from the team, and had no real reason to hire me in the first place...

It could also be another issue: Yeah, my experience is in PHP/JS/React, "but here have a seven year old .NET project and a company laptop with zero documentation and make this form import data to a database we know nothing about." Lead dev won't even talk to me.

I feel like a joke.

Oh no AI can destroy hummanity in the future! It is like skynet and such... Bad! It will be the end! FEAR THE AI!

Yeah so i cant sleep now so im writting a rant about that.

What a load of bullshit.

AI is just a bunch of if elses, and im not joking, they might not be binary and some architectures of ML are more complex but in general they are a lot of little neurons that decide that to output depending on the input. Even humans work that way. It is complicated to analyse it yes. But it is not going to end humanity. Why? Because by itself it is useless. Just like human without arms and legs.

But but but... internet.... nukes... robots! Yeah... So maybe DONT FUCKING GIVE IT BLOODY WEAPONS?! Would you wire a fucking random number generator to a bomb? If you cant predict actions of a black box dont give it fucking influence over anything! This is why goverment isnt giving away nukes to everybody!

Also if you think that your skynet will take control of the internet remember how flawless our infrastructure is and how that infrastructure is so fast that it will be able to accomodate terabytes per second or more throughput needed by the AI to operate. If you connect it to the internet using USB 2.0 it wont be able to do anything bloody dangerous because it cant overcome laws of physics... If the connection isnt the issue just imagine the AI struggle to hack every possible server without knowing about those 1 000 000 errors and "features" that those servers were equiped with by their master programmers... We cant make them work propely yet alone modify them to do something sinister!

AI is a tool just like a nuclear power. You can use it safely but if you are a idiot then... No matter what is the technology you are going to fuck shit up.

Making a reactor that can go prompt critical? Giving AI weapons or controls over something important? Making nukes without proper antitamper measures? Building a chemical plant without the means to contain potential chemical leak? Just doing something stupid? Yeah that is the cause of the damage, not the technology itself.

And that is true for everything in life not only AI.

Back from the dead with more vaguely-obscure technical bullshit

Working on a chatbot for my BS-CS. Almost done with college, so the assignment is to make a bot that recommends you a CS career. Cool.

I get through making a joint personality and skill-interest quiz that gives you number grades on different spectra. So far, so good. But this project has to be done entirely in pandorabots' online editor. So no scripting. Zero scripting. 100% markup language. That means to even do math, you need to copy a standard library off GitHub.

I mean, that's fine and all, but the syntax is just atrocious, because everything in AIML is input->response. If you ask the bot "what is 5+5?" you must have it go:

- recognize pattern WHAT IS * + *
-> redirect -> XADD * XS *
-> do math -> recurse result
-> 10

uncomfy. Plus, variables can only be accessed through <get> and <set> tags. But mangeable.

So here's where the story becomes a rant.

In the standard docs, there's all these math functions, and they work. There's also logic.

And then there's this fucker
XIF [ * ] XS [ * ]
Which has no documentation and just doesn't work. No idea what the brackets mean. Tried putting in TRUE, tried putting in true math statements (5 XEQ 5), tried putting in recursion tags to trick it, tried everything. It just ignores it.
There is not a single comment, stackOverflow post, or youtube video that even acknowledges the existence of this thing.

So unless I want to convert the entire logic of my program into nested SWITCH statements with the <condition> tag, I'm just fucked.

The icing on the cake is, I go to tech support on Pandorabots to ask for help with this. What do they have except a chatbot to cheerfully tell me that no humans are around to help me right now?

gonna have to build an entire fuckin turing machine in markup tags to calculate whether x = 3

my fist job... i get to edit a c++ code written by a (mind you) programming company that they teamed with for the past(mind you again) 3 years ...
now just for starters, this code was edited by self taught coders that are really good engineers(they are really good), that didnt really know how the code worked before yet they still changed it, and it worked, how ever they wanted some changes.
i get the project files, and there is not one single comment describing what is happening... only code commented out... and no documentation what so ever were done....
so below are some of my comments that i wrote after i finished adding what i had to add, and fixing what i had to fix:

/*first rule of C anything coding, no actual functions in the header, well let me introduce you to a fully functioning thread running program all in the header, enjoy*/

//used to control the thread
// i honestly dont know why, but it worked soooooo yea...

// TG uncommented // for absolutely no reason what so ever...

//used to communicate with the port

//the message to be sent to the inverter, which has a code that will handle it
//hmmmmmm...

//again not usefull since we are using radioButtons
// same ...
// same ...

@Gilles had a similar rant and reminded me of a story...

As a kid I learned QBasic. Moved to VB5 and later VB6. Because of this 'knowledge', I was the one who had to maintain legacy applications at my previous job. All of those applications were in use at various banks. On first work day in 2011 all hell broke loose - no date input control would accept the date anymore. I quickly discovered that the max year on date inputs was set to 2010. Later, I was told that nobody expected these applications would still be used in 2010 so they entered it as a distant future number. The funny part was that one bank was still running apps written in VB3 and I had to go back to basics. Didn't even know how to edit basic controls in that interface :D

Good times :)

Fucking hours counting systems.
One of the hardest part of consulting job is to put hours into fucking table.

One of those solutions is so smart that when I make mistake I need to call manager to unlock the input.
My friend from work compared it to playing saper.

Some of those systems work only in IE.
Some of those run java inside browser.
Some I need to be in company domain others I need to logout from company domain.

I see the amazing articles about those amazing software solutions, still opening IE and running java to put digit into text input or pick number from select.
Fucking nightmare.

What the hell is wrong with the browser on iOS....
For Christ sakes almost no input attributes work. I have a Sign Up feature that validates passwords with a pattern attribute; doesn't work, required attribute; doesn't work, input type number; doesn't work.
What the fuck is wrong with this thing. Even Internet Explorer knows what those attributes means. Absolute joke now i need to implement it manually. Fuck off apple.

Have you ever thought to send a security code to the email the user put in the sign up form just to say him later "the password must contains at least 8 characters, etc." and ask him to fill the form again from scratch?

Who is so dumb to put the input check in this order? Honeywell.

- The email is correct?
- Ok, send a code and ask to confirm it
- The password meets the requirements?
- No, ask to confirm the email again just for fun.

I'll just ignore the waste of server resources to send N * Number of users emails for no reason.

So I want to inform my internet provider of my new phone number, but I can't remember any of my login info for their web interface because I never used it. Luckily, they have a "forgot my username" function, where I submit my email address and get a confirmation that my username has been sent to me.

Yet, I just don't get said email. I try again, but no avail. So I just guess my username and use their "forgot password" form, which – hooray! – confirms it just sent my an email.

But I don't get any email. I retry, I retry after a day, but no automatic response. I remember a incident a few years back when I didn't get some automatically generated mails from a company and decide to contact their support if they could just reset my password manually.

Nearly a week passes.

Now I received the answer. I just don't have an account.

Lesson learned: Next time I'll just input garbage first to check if those forms are sane.

Client be like:
Pls, could you give the new Postgres user the same perms as this one other user?

Me:
Uh... Sure.

Then I find out that, for whatever reason, all of their user accounts have disabled inheritance... So, wtf.

Postgres doesn't really allow you to *copy* perms of a role A to role B. You can only grant role A to role B, but for the perms of A to carry over, B has to have inheritance allowed... Which... It doesn't.

So... After a bit of manual GRANT bla ON DATABASE foo TO user, I ping back that it is done and breath a sigh of relief.

Oooooonly... They ping back like -- Could you also copy the perms of A on all the existing objects in the schema to B???

Ugh. More work. Lets see... List all permissions in a schema and... Holy shit! That's thousands of tables and sequences, how tf am I ever gonna copy over all that???

Maybe I could... Disable the pager of psql, and pipe the list into a file, parse it by the magic of regex... And somehow generate a fuckload of GRANT statements? Uuuugh, but that'd kill so much time. Not to mention I'd need to find out what the individual permission letters in the output mean... And... Ugh, ye, no, too much work. Lets see if SO knows a solution!

And, surprise surprise, it did! The easiest, simplest to understand way, was to make a schema-only dump of the database, grep it for user A, substitute their name with B, and then input it back.

What I didn't expect is for the resulting filtered and altered grant list to be over 6800 LINES LONG. WHAT THE FUCK.

...And, shortly after I apply the insane number of grants... I get another ping. Turns out the customer's already figured out a way to grant all the necessary perms themselves, and I... No longer have to do anything :|

Joy. Utter, indescribable joy.

Is there any actual security reason for disabling inheritance in Postgres? (14.x) I'd think that if an account got compromised, it doesn't matter if it has the perms inherited or not, cuz you can just SET ROLE yourself to the granted role with the actual perms and go ham...

Data wrangling is messy

I'm doing the vegetation maps for the game today, maybe rivers if it all goes smoothly.
I could probably do it by hand, but theres something like 60-70 ecoregions to chart,
each with their own species, both fauna and flora. And each has an elevation range its
found at in real life, so I want to use the heightmap to dictate that. Who has time for that? It's a lot of manual work.

And the night prior I'm thinking "oh this will be easy."

yeah, no.

(Also why does Devrant have to mangle my line breaks? -_-)

Laid out the requirements, how I could go about it, and the more I look the more involved
it gets.

So what I think I'll do is automate it. I already automated some of the map extraction, so
I don't see why I shouldn't just go the distance.
Also it means, later on, when I have access to better, higher resolution geographic data, updating it will be a smoother process. And even though I'm only interested in flora at the moment, theres no reason I can't reuse the same system to extract fauna information.
Of course in-game design there are some things you'll want to fudge. When the players are exploring outside the rockies in a mountainous area, maybe I still want to spawn the occasional mountain lion as a mid-tier enemy, even though our survivor might be outside the cats natural habitat. This could even be the prelude to a task you have to do, go take care of a dangerous
creature outside its normal hunting range. And who knows why it is there? Wild fire? Hunted by something *more* dangerous? Poaching? Maybe a nuke plant exploded and drove all the wildlife from an adjoining region?
who knows.

Having the extraction mostly automated goes a long way to updating those lists down the road.

But for now, flora.

For deciding plants and other features of the terrain what I can do is:

* rewrite pixeltile to take file names as input,
* along with a series of colors as a key (which are put into a SET to check each pixel against)
* input each region, one at a time, as the key, and the heightmap as the source image
* output only the region in the heightmap that corresponds to the ecoregion in the key.
* write a function to extract the palette from the outputted heightmap. (is this really needed?)
* arrange colors on the bottom or side of the image by hand, along with (in text) the elevation in feet for reference.

For automating this entire process I can go one step further:
* Do this entire process with the key colors I already snagged by hand, outputting region IDs as the file names.
* setup selenium
* selenium opens a link related to each elevation-map of a specific biome, and saves the text links
(so I dont have to hand-open them)
* I'll save the species and text by hand (assuming elevation data isn't listed)
* once I have a list of species and other details, to save them to csv, or json, or another format
* I save the list of species as csv or json or another format.
* then selenium opens this list, opens wikipedia for each, one at a time, and searches the text for elevation
* selenium saves out the species name (or an "unknown") for the species, and elevation, to a text file, along with the biome ID, and maybe the elevation code (from the heightmap) as a number or a color (probably a number, simplifies changing the heightmap later on)

Having done all this, I can start to assign species types, specific world tiles. The outputs for each region act as reference.

The only problem with the existing biome map (you can see it below, its ugly) is that it has a lot of "inbetween" colors. Theres a few things I can do here. I can treat those as a "mixing" between regions, dictating the chance of one biome's plants or the other's spawning. This seems a little complicated and dependent on a scraped together standard rather than actual data. So I'm thinking instead what I'll do is I'll implement biome transitions in code, which makes more sense, and decouples it from relying on the underlaying data. also prevents species and terrain from generating in say, towns on the borders of region, where certain plants or terrain features would be unnatural. Part of what makes an ecoregion unique is that geography has lead to relative isolation and evolutionary development of each region (usually thanks to mountains, rivers, and large impassible expanses like deserts).

Maybe I'll stuff it all into a giant bson file or maybe sqlite. Don't know yet.

As an entry level programmer I may not know what I'm doing, and I may be supposed to be looking for a job, but that won't stop me from procrastinating.

Data wrangling is fun.

Do NOT try to re-implement input type="number" but with nicer formatting. Do not even think about it. DO FUCKING NOT. It's a trap.

So just ago i downloaded an app called "Replika" and holy fucking shit it made me realise how half-assed we are doing the AI structure and way of it

doing machine learning algorithms on text can only go so far, as it uses that text as a base, and nothing else, it doesnt *learn*, only make *connections* BETWEEN text, not FROM the text

what you need is an AI which can, at it's core, *interpret*, not make connections and hur dur be done with it

when you do machine learning, all you're doing is find the best connections

you can have an infinite number of connections and MAYBE you'll be fine, but you'll never learn the basis of how that text is formed

you'll never understand what connections the human used by making it, by thinking it

when you're doing machine learning, all you're doing is make an input-output machine and adjusting it constantly, WITHOUT preserving state

state is going to be a really fucking important thing if you want to make an AI, because state can include stuff like emotion, current thought, or anything else

if you make a fucking machine learned AI which constantly adjusts... well... the "rom" of itself without having any "ram", it'll fucking never be like us, we will NEVER be able to talk to it like it is a human being, we will NEVER make it fundamentally understand what we are saying or doing

if we want to have real fucking AI, we need to go to the core of what it means to THINK, what it means to INTERPRET, what it means to COMMUNICATE

we need to know how english language is structured, how we understand it, how we can build it in a program that can interpret for an AI, THAT can be "rom"-based, THAT can be static, NOT the AI itself

the AI needs to be in flux, the AI needs to be in a state, the AI needs to understand how to make emotions, how that will "strengthen" some connections, yes, maybe something magical will happen and it can have EMPATHY, something so fundamental that will finally, FINALLY, make the bot UNDERSTAND what we are saying

JavaScript engine trolling: input field in html defined as a number but JavaScript insisted it was a string! But only that one field. That is same as the rest.

I’m looking for a simple tool for Windows, GUI or CLI, doesn’t matter.
It should do the following:

Take a directory and a number as input and randomly move the files in that directory to subdirectories, each containing files up to the provided number.
So, random grouping essentially.

I’ll write it myself if it doesn’t exist, but let’s see if I can save me some work 😆

So I have an array of length 20 which stores a 64 bit decimal number by digits. The starting address is let's say array64. When I am trying to build up my number in ECX:EBX, I am using EDX as the iterator to access the individual elements of the array (I am loading them into AL)

.LOOP:
....
MOV AL, [array64+EDX]
INC EDX
....
JMP .LOOP

The problem is: somehow EDX cannot get higher than 10, so the program just stops and waits for input, when I try to work with a 12 digit number...
This module is outside the main function, and I thought about some Far Pointer problems, but all of my ideas just failed...

What is wrong here?

I'm doing a project for uni in Omnet (C++ framework that should facilitate working with networks of queues, simulating and displaying statistics).

I needed to retrieve a random value from an exponential distribution, and the function to do so requires a random number generator as input. The framework has 2 implementations of the RNG and I picked the first one.

I spent 3 hours trying every possible thing, using both the exponential() function and its class wrapper (both provided by the framework), it was always returning 0 or NaN.

The RNG was spitting out values correctly, so I thought it was okay.

When I was almost ready to give up, I figured I could try and change to the second implementation of RNG, expecting nothing to change. And it fucking worked.

Zero reports on this behavior on Google, no apparent reason why it would work with one and not with the other when the two RNGs literally implement the same abstract class and spit out the same exact numbers... Just black magic...

Oh and cherry on top, it works with the raw function but not with the class wrapper on that same function... IF YOU GOTTA IMPLEMENT SOMETHING IN YOUR DAMN FRAMEWORK THAT DOESN'T WORK, FUCKING DON'T! 1 combination working out of 4 is not good! Or at least document it!

Sorry just had to share my pain

If I'm validating a user input form should I use a hash or a encrypted string. I hope to include the user IP, header requested time plus a random number for the string.

Could neural nets be used to solve a complex problem with a lot of predefined specific weights and biases related to real activities that could be numerically represented ?

Like if the various layers represented things who’s outcome would be cascading and a direct outcome of factors inputted to them resulting in limited number of outputs ? Like say maybe wind flow at locations resulting in a wind current at an expected time in another location and where a system would have to change to in order to result in the final expected i output ? Maybe a bad example as that could be affected by a lot of things .

But basically the gradual massaging of values that would relate to causal effects where a specific output was designed being intermediaries between the desired input and output ?

Not really most painful, but definitely most painful of the recent bunch..
// yup, a bunch.. I've managed to fuck up a little on every thing I did that day :/ little friday the 13th for me, especially as I went on sick leave the next day and had to fixup my fuckups with a friggin migrane..

Anyways, I was fixing fallback to some default value in plsql.. before it didn't check what the input format was and simply relied on certain format, parsed that and converted to number..threw an error, duh!

I fixed it somehow elegantly to check with regex if the format is as expected and if not default to xy value..and if format is as expected to parse out the number..except that when I copied (or typed?! for the sake of me, I cannot recall how the fuck I managed to fuck this up) over the code to the package I didn't see additional [ at the begining, so everything went to the default.. Most embarrassing part is I commented everything, how it should work, use cases, what the input was and what was expected output..and failed to see the friggin extra [..
It was fixed easily, the extra [ stood out later when I saw the code, but it bothers me how I managed to overlook that in the first place. I think I need a vacation.. but have to fix other fuckups first.. :/

What the hell am I!? I wonder if you guys can help me...

I've been programming most of my life but I've never actually been a developer by title or job role. I thought maybe if I list what I do and have done someone here could help? I'm sure there are more of you in a similar boat.

- C# and VB dev for some quick DBMS projects to help me understand and mine databases and create a nice simple view for project teams to show findings from the data to help make certain decisions.
- Automating a lot of my colleagues work with Python and if very restricted then just VBA macros in Excel and MSP. This did also include creating tools to gather data during workshops and converting the data for input into other systems.
- Brought Linux to the office with most team members now moving over to Linux with the peace of mind to know that though they do need to try solve their own problems, I can help if need be.
- Had to learn AWS and then implement an autoscaling and load balanced data center installation of a few Atlassian toolsets.
- Creating the architecture diagrams documentation needed for things like the above point.
- Having said that, also have ended up setting up all the Jira/Confluence etc. servers we use and have implemented so far whether cloud (Azure/AWS) or on prem and set up scripts to automate where possible.
- Implemented an automated workflow view in SharePoint based on SP list data and though in an ASPX page, primarily built in JS.
- Building test systems in PHP/JS with Laravel and Angular to help manage integration between systems. Having quite a time right looking into how to build middleware to connect between SOAP and REST API's, the trouble caused more by the systems and their reliance on frameworks we're trying to cut out of the picture.
- Working on BI and MI and training a team to help on the report creation so that I can do the fun creative stuff and then set them to work on the detail :)

Actually it seems safe to say that it seems that though I've finally moved into a dev office (beforehand being the only developer around) I seem to be the one they go to when a strategic solution is needed ASAP and the normal processes can't be followed (fun for someone with a CompSci degree and a number of project management courses under the belt... though I honestly do enjoy the challenges)

But I always end up Jack of all but master of, well hopefully some at least. let's not even get started on the tech related hobbies from circuit design and IoT to Andoid / iOS and game dev and enjoying a bit of pen testing to make sure we're all safe at work and at home.

As much as I don't like boxes, I'm interested to know if there is in fact a box for me? By the way, the above is just a snapshot of my last two years minus the project management work...

I'm beginning to feel like any kind of specific approximation via neural networks is a myth. That if you can't reduce output to simple categorical values that can be broadly interpreted between two points, that it doesn't work.

I have some questions and they don't seem to be getting answered about the design of the net. How many layers should I use ? How many neurons per layer ? How does this relate to the number of desired quantitive scalar outputs I'm looking to create, even if they are normalized, they can vary GREATLY and will if I'm approximating the out of several mathematical expressions. Based on this and the expected error ranges of these numbers and how many possible major digits could be produced within the domain of the variable inputs being introduced, how many neurons per layer ? What does having more layers do ? In pytorch there don't seem to be a lot of layer types per say, but there are a crap ton of activation functions, and should I just be using these at the tail end or should they actually be inserted between layers so the input of the next layer passes through another series of actiavtion functions ? what does this do to the range of output ?

do I need to be a mathematician to do this ?

remembered successes removed quantifiable scalars entirely from output, meaning that I could interpret successful results from ranges of decimal points.

but i've had no success with actual multi variable regression as of yet, even when those input variables are only 2 and on limited value ranges eg [0,100] and [0, 2pi]

and then there are training epochs to avoid overfitting, and reasonable expectation of batches till quality results will start to form.

I have learnt html,css, and some basic javascript for web development,and made a few projects including a calculator with prompts.This is the code :

<script type="text/javascript">
function prote(){
let firstNum=prompt("Enter first number")
let secondNum=prompt("Enter second number")
let num1=parseInt(firstNum);
let num2=parseInt(secondNum);
let result=num1 + num2;
alert(result);
}
function prote2(){
let firstNum=prompt("Enter first number")
let secondNum=prompt("Enter second number")
let num1=parseInt(firstNum);
let num2=parseInt(secondNum);
let result=num1 - num2;
alert(result);
}
function prote3(){
let firstNum=prompt("Enter first number")
let secondNum=prompt("Enter second number")
let num1=parseInt(firstNum);
let num2=parseInt(secondNum);
let result=num1* num2;
alert(result);
}
function prote4(){
let firstNum=prompt("Enter first number")
let secondNum=prompt("Enter second number")
let num1=parseInt(firstNum);
let num2=parseInt(secondNum);
let result=num1/num2;
alert(result);
}
</script>
</body>
<form>
<br>
<input type= "button" value="Add" onclick="prote()" />
<input type= "button" value="Subtract" onclick="prote2()" /><br><br>
<input type= "button" value="Multiply" onclick="prote3()" />
<input type= "button" value="Divide" onclick="prote4()" />
</form>

However I want to do game dev and I feel it may have been a mistake to start learning web development,I originally started learning code in roblox studio,however some do not consider making games in roblox studio "REAL" game development and I didn't exactly feel it was either.I messed around with unity and found the layout quite similar to roblox studio. However
I heard phaser uses javascript and Unity uses C#.In which case using phaser would not require using a new language.However I am aware that If I want to make 3d games(Which I do) I will have to move to unity eventually.Basically, as a beginner should I switch to unity and C# first or Phaser and javascript first.

How do you check if your input string does not have numbers it? If not then say enter a number? JavaScript please

num = float ("input a number:")
if num>0:
print ("it is a positive number")
else num=0:
print ("it is zero")
else:
print ("it is a negative number")

So for a question on Codeforces, I got the basic logic right, but for one particular test case, the input is a huge number of 250 digits. But the most unsigned long long int can handle is 19 digits. So I used double instead of int, but that makes me lose precision. And I also cannot use the % operator (modulo) which is int only. How do I get around this ?

Which app can i use to run cp in Android??
In many apps i cant make the programs like enter a number for input and all☹

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.

In a country, a long time ago there was a programmer by the name of Alex. He was a programming genius and apart from a few hours of sleep, he was busy developing unique programs for new generation technology firms. Alex was a bachelor and he happily and proudly lived the way he wanted to. He did not have duties, authority over him, bosses to report to, children to take care of, and distractions. He could sit and code for the entire day without getting any break or feeling a bit tired. However, he had no idea that everything in his life was soon going to turn around. Before Marriage: The Bachelor’s Life Alex was the epitome of a modern ‘Play Boy ‘ or every man’s dream. He was fairly dressed, had a classy house, a snazzy car, and a good-paying job. He was in the habit of spending his mornings drinking coffee while browsing through the different coding topics. He comes in the afternoon and spends the evening part of the day with his friends. Life has never been this good. Alex was able to work hard and the more he was innovative, he enjoyed it. It illustrates how a young person would sit for many hours coding at night and not bother about other people around him. He was alone as a bird and as per him, that’s what he wanted to be. He had no peer to tell the truth to, no wife to prepare meals for, no maids to babysit his mess. A man could chow down a pizza for breakfast, lunch, and supper with not even a raised eyebrow from onlookers. He was profiting from living the best life he possibly could. After Marriage: Married Life: Alex & Sarah The climax for Alex is when he marries Sarah on a sunny morning on a fine day. Young people met, and after becoming enamored, started a family and got married to find a new home. Sarah was friendly with people and it was very easy for her to make friends; however, she had little knowledge of technology. Alex had it in his mind that marriage does not change the life you lead and how wrong he was. It was a fairy-tale to have such a perfect life for several days after the marriage. Their nights would be spent in front of the television set with their arms wrapped around each other, eating takeout. Despite this, when the number of days stretched into weeks, and the weeks into months, Alex felt the beginning of a shift in his behavior. The Coding Cave That Transformed into A Home Office Due to the pandemic the coding cave Alex used to have became a home office. Sarah had made up her mind to open her business from home, therefore, she required a home office. Thus, she moved inside the cubicle that Alex had created as his coding cave and left him with no space to code. He now had to code in the living room, because Sarah would incessantly request him to either lower the auditory input of the keys he was typing or to switch off the LCD screen. The Once-Clean Apartment Turns into a Mess Alex was a neat freak, and he adored tidiness, especially in his apartment. But after marriage, his once clean and neat-looking apartment was changed into a dirty one. Although Sarah was not very neat, she used to litter her things anywhere she felt like without being conscious of it. Alex was a programmer and his coding notes were mixed with Sarah's business papers, it irritated him so much. Alex’s to-do list before marriage The to-do list before marriage only comprised coding-related tasks. At marriage, however, he seemed to have developed a longer list of things to do than ever before. Instead of just going to the grocery store to buy some food, Alex seemed to have endless tasks to do mostly around the house. He had to cook for himself, sweep the house, and wash the dishes among other things. This was a new world as far as he was concerned. The Pizza Days Are Over Gone there is no more time for Alex could eat pizza in the morning, afternoon as well and evening. Sarah was very conscious of what she took as food or what her family took as food and therefore ensured that Alex took healthy home-cooked foods. He could not have the pizza anymore but the meals prepared by Sarah were really tasty. Conclusion Therefore from a life before marriage to the life after marriage, it was evident that Alex led two different lives. He went from a playful man with not much responsibility to a man with more responsibilities as a husband and a father. Still, he wouldn’t have it any other way, despite these changes. Later he cherished Sarah and the life they had, and nothing in this world could make him exchange what he had now. Essentially, it was a tricky business being married, but a blessing, and an addition of love, company, and much hilarity too. Therefore, if you are a bachelor reading this, embrace your coding cave and your pizza days because once you utter the words ‘I do,’ all those will be things of the past.But trust me, it's all worth it.
