- Buy 0.5 BTC (couldn’t afford more)
- Forgot about it

Year 2016

- Remembered I had bought BTC
- Looking like crazy for my USB drive
- Found it!
- Insert it into PC

My boss literally spends half an hour finger-fucking his phone on the mobile site to find "bugs", that I can't replicate. A combination like: swipe, pinch, landscape, portrait, back pinch, open new tab, close tab, ash cigarette on phone, dunk in toilet, dry, double tap... Aha I've found a bug, there's 0.5 pixel line of space between the bag header and the browser bar.

A few of Stux's !dev pet peeves

1) People that walk slow as fuck in the middle of a side walk. Like hurry uppppp. I've gotta get 0.5 miles in like 8 minutes and you blocking the walkway doesn't help.

2) People that don't understand how side walks work. Treat it like the fucking road. ⬇️⬆️ Is the pattern in which you should walk. It's not rocket science.

3) People that start walking up the bus steps as I'm clearly walking forward to get off. Ffs let me off and THEN get on you stupid bitch

4) people that bike or ride their skateboard/longboard around campus but are moving slower than I am while walking. If you're gonna do that hop the fuck off and carry the damn thing.

5) people that don't try to solve an issue with their code on their own BEFORE they call the professor over. (There goes the !dev lol)

6) people that act like their favorite musician or athelete or actor or anyone fucking famous they play kiss ass with can't be criticized. Just bc they're famous and/or good at what they do sure asf doesn't make them perfection and I retain the right to voice my opinion.

My name is Stuxnet and you're watching Disney Channel.

So i was working with a small company which were developing software for insurance sector. It was decided then that there should be an app for windows phone community and i was hired to that job.

It took me almost a month to finish the job. Please keep in mind that project was huge and already developed for android counterpart and was a hit in market. This was a chance given to me to prove myself and i proved it.

First month was fantastic for the company as software the company made was not available for windows phone. Price has been set for the software was higher in those time. Almost $15.

Excited by the success i added some more features which were not available on android counter part.

But price was very high. Even i asked management to drop the price because there were less windows phone user but no body listened.

Result : in a year app has made roughly 5000 download in which only 200 paid the actual price. Company asked me to take down the app from store. I was blamed for my over confidence in adding features that this made app less usable. They did not say a word to business managment team. I was fired.

Rough, cruel world.

6 month ago i published my app for same purpose with same feature set and different UI. And made it free. Completely free. Added a link to pay developer $0.5 or Rs 30.

Result: i have now 10 thousands plus download in last 4 month in which almost 3000 users have donated already.

Now i have my resource and my confidence and making an android app for same purpose.

This is my story and is not fake, i am 28 years old. If you think you can, you can.

Amen.

The nub nub still hasn't mastered the art of the button 😂

In a programming contest, I forgot how to round numbers in Java, an I needed a 3 number rounding, so I multiplied the number by 1000, then sum 0.5 and convert it to integer so the decimal part would be gone, finally, just print the number except the 3 last digits as a string, put a period and print the other 3 digits.
I must say I'm not proud of that.

Should I ever design a programming language, I'll aim for the golden middle course and let arrays start at 0.5.

While sitting on the toilet, it struck me:

int y = (int) (x+0.5); //x is a float

is exactly the same as:

int y = Math.round(x);

It's such a simple thought, yet, I realized that just now.

> 0.5 + 0.1 == 0.6
> true

> 0.1 + 0.2 == 0.3
> false

guys, i've got an amazing idea that will make us all rich!

now - hear me out - we start putting publicly available scooters in major cities around the world

these scooters are ingeneous and differentiate us from any competition because they are yellow instead of green or blue!!!

we're hiring now!!! who wants to join me?!?!? we're a dynamic, motivated, and hard working team. we don't have amazing benefits, a relocation bonus, an office, a tech gear stipend just yet, or a salary, but we do offer a generous 0.5% equity and our series A is just around the corner - promised - within a few weeks time! we're looking for a candidate with 10+ years experience in all of the following: PHP, MySQL, TypeScript, JavaScript, Python, C#, C++, Rust, Go, and Fortran. Additional skills, but not totally required include blockchain development, prompt engineering, and building GPT sized LLMs. DM me for details!

Update on my previous kernel rant, I finally compiled it down to just 2.9GB! included all the needed modules and I am also able to boot off of it!

Great news is, that sound both on speakers and also through headphones work, bad news is, that there's some overlayed buzz/distortion, the playback is higher pitched and chrome for some reason plays videos "normally" if you set it to 0.5 speed, else the video get sped up in the "normal" speed setting, well fuck me, but atleast I am closer, also as always thanks to arch wiki, that has tons of resources.

It might be some of the quick hacks that causes this, that I used in the past to make sound work through an external usb card atleast, so might be worth it just reinstalling it all.

!rant

Reduced a page load time from 23.8 seconds to 0.5 seconds by disabling tracking of entities on the page. Felt awesome.

The one colleague who wants to type -0.5 but accidentally types 0-.5 and leaves it like that because the compiler accepts it and in the end its correct.

Hours of refactoring just to get 0.5 seconds increase in performance per document generation.

Sounds small but makes a big difference when generating 100k documents.

Still not happy with it though...

FFUUUuucccckkk me sideways. So I decided to look into USB type-c's power delivery and alt modes. Cause I kinda want to make an adapter card to run my displays over a single cable. TLDR of the rest: USB-C has some huge capabilities which noone is interested in using since its way to complex to handle for what its worth in the end.
Now PD alone is kinda ok to deal with since a lot of powerbanks use it and some hobby guys documented how to work with it. I find it really odd thou that you NEED to use a dedicated IC for using the configuration chanel to negotiate how much power you can draw. Why the USB standard didnt use some simple 5V low speed signalling? Also the standard says that you only have to implement 5v 0.6A with every other power level being optional. (This is also true for cables. Most manufacturers use only the USB 2.0 standard for them and brag about how fast type-C is. ლ(ಠ益ಠლ) )
Now to the alt modes. These motherfuckers are a real shitshow to deal with. First you need a Mux to deal with USB-C's two way insertion, so your signals wont get flipped. Next thing is that you have four lanes at your disposal in alt mode. Which you can either use for four Display Port Lanes or two DP lanes and two USB 3.0 lanes. (You always get USB 2.0) Now you may think that there would be one simple chip to do it all? Nope you need atleast two at the price of 6$ each. One for PD and one for Alt modes. Both are very hard to solder (QFN, 0.5 mm pitch 40+ pins) TI ended up being the only one with a decent offering of IC's that do what I need. As for working with them, you would think that you just slap a simple MCU on there that communicates over I2C or SPI to configure the chips? Nope! You program the chips memory from which it configures itsself. And the programming is done with some TI tool which gives me no idea as to how you can handle everything whith no control logic behind it.
Looking into alternative IC's leaves me with cypress semi. And their documentation is basically a total mess. I wanna know what that chip is good for and what I need to do to make it work. I dont care about technical details mixed with marketing jargon nobody understands. And I really despise that I have to register just to download a datasheet. Especially since there is no info about it on the main page.
And this whole rant hasnt even touched the topic that USB-C only uses DP and nothing else. So you better hope that you have DP++ so you can use a passive conversion.
This was my Ted Talk about USB-C. Some info in it may be subject to my stupidity and errors as it currently is 02:15 in the morning and I need some sleep.

Remember the post about bruce's constant?(4.5099806905005)

Well apparently theres a convergent series for it found all the way back in 2015.

Apparently its an actual thing. Which connects e to the square root of this series.

And it converges on (bruce-1)**0.5.
I confirmed it myself.

The two people who found the series that converges are N. J. A. Sloane and Hiroaki Yamanouchi

Thank you Sloane and Hiroaki!

The actual formula is a series of embedded square roots with the repeating numbers 1,4,2,8,5,7
like so...
sqrt(1+sqrt(4+sqrt(2+sqrt(8+sqrt...

What this means is you can find e using this series.

All you do is run the series, raise by a power of 2, add 1, calculate J and K like so

J = log(2, 1.333333333333333) / log(2, 2)
K = log(2, 1.333333333333333) / log(2, 3)

then calculate (J+K)-(bruce-1)
and out pops our buddy e:
2.7182818284591317

I guess I bullshitted myself for so long, that I didn't believe people like scor when they said they legit witnessed by math skills grow.

Or maybe a blind squirrel occasionally DOES find a nut.

Pretty cool find either way.

So at this startup i was single iOS dude age 34, android had 1.5 dudes, one older, one you ger. That 0.5 younger was tech director, really good, so they churned for two guys. Millenial, nice guy, never making conflict, just being sleazebag.

Nobody explained to boss why iOS was always late with features, even when i complained. So i got help, 10 months later, project was unpolished but stable, codewise. Now i interview and hire a guy, age 27, who was all yeah dude no problem, and that being my first interview, i fell under his friendly appearance. I ignored a fact that he didn’t know 90% of stuff i was asking him, because he was so friendly and outgoing and we will do anything attitude.

The guy knew very little, was childish and irresponisble. He showed at work at noon. He started telling me what to do, his senior collegue who started the project. He argued about everything that i would tell him. So i spent three to four hours a day charting with him, because we were in different cities. He had two uears of experence, but he was below junior level. And he refused any of my advices for learning in free time. No, he said, thats my free time, you will not tell me what to do. Well, how do you plan on being better, i asked. He said, i learn by doing. But, since he was at his job only six hours a day, instead of eight, and since he was productive only for 2, i guess he was lazy.
He would deliver a UI he would make, without business logic, and tell it is done. Then clients would call me and ask why text fields are not saved..

This all took me month to understand. I lost time, i lost trust, and soon he was fired.

But, soon i was fired also, replaced by another two devs who i had interviewd and formed a team. I was discarded as trash, just like that. I have even worked overtime to catch up with android guys, unpaid.

Took me year to recover mentally from this.

Lessons learned: be objective when interviewing. Job is business, not friendship, trust no one, keep neutral on work. Leave honesty for someone else, honesty will be used against you. Never criticize two girls in office who disturb developers by talking about sex and dicks all the time, dressed sexy, they are girlfriends of people ranked above you. Leave code perfection for your projects.

Fun issue

Swedish client is unable to enter a currency conversion rate in a field and submit. 'Not a float' well we can clearly see that it is a float when he does it (0.5 for example), not an issue for us though.

Reproducing was a nightmare, eventually it boiled down to the fact that the framework we were using had automatic locale checks. Now because our numeric fields are actually weird text fields (front end nonsense), it was converting the period to be a comma (Swedish people would write 0,5 normally). And if you actually entered 0,5 the range check (0.01-1000) failed because it couldn't parse the comma (no locale check on that one)

Godamn facepalm. Really confused the hell out of us when we saw the error, had to go diving through library code. To top this off, locale checks are supposed to be disabled as of about 2 years ago

Has your character and level of patience changed since the beginning of your dev career?

I have a feeling that stress mixed with a constant exposure to shitty code, hacky web stuff and abysmal stylesheets have been eroding my immense pillars of patience.
10 years ago I was able to try stuff out for hours with full motivation. I've started a habit of low level swearing recently and sometimes gain a strong urge to punch through a monitor.
I don't have it every day, but it seems worrying...

... or maybe it's just all due to having to HACK the shit out of everything to support fucking IE11.
This complete fuckery of a browser is still in use by about 0.5%... absolute braindamaged imbeciles if you ask me!

I just finished up an absolute cesspool of a project. I was seriously reconsidering a career change to something less stressful, like welding on a high-rise building, or capturing Somali pirates.

Next project is supposed to be a walk in the park, and probably still will be.

MGR: You're starting a new project next week. Prismic for the CMS, and NextJS.
ME: Oh, okay, cool. Well, let me get up to speed on Prismic and Next since I haven't used either of those.
Spent some time last week - easy enough, nothing really new/ground breaking here.

Sprint 0.5 Kick off meeting today
MGR: By the way, we're still using Prismic for the CMS, but we're gonna go ahead and use Gatsby instead of Next.
Me: ... *facepalm

I’m fucking lost.

So, situation. I have a SQL table with about 3M rows (not a lot).

I have indexes. Indexes are used. BUT when I add where clause (On indexed column), it’s super slow. Around 10 seconds.

If I do select * (ALL 3M rows) and THEN I filter then on webserver side, it takes 0.5 seconds.

HOW my manual filtering is faster than DB filtering with indexes? I even tried bubble sort. Bubble sort is faster than SQL ‘where’. HOW ?!

I do not understand….

And if I add group by….. WELL, 25 seconds SQL time. 2 Seconds if I do select all and group by in code manually.

Does not make ANY sense to me.
What am I missing ?

While I was exploring multiplication tables I stumbled on something cool.
Take any power of 2 on the multiplication chart.
Now look at the number in the bottom left adjacent box.
The difference of these two numbers will always be a Mersenne number.
Go ahead. Starting on the 2's column of a multiplication table, look in the bottom left of each power of 2 and get the difference.

2-2 = 0
4-3= 1
8-5 = 3
16-9=7
32-17=15

etc.

While the online journal of integer sequences lists a lot of forumlas, I just wrote what came to mind (I'm sure its already known):
((2**i)-(((2**i)/2)+1))

The interesting thing about this is it generates not only the Mersenne numbers, but if you run i *backwards* it generates *additional* numbers.
So its a superset of mersenne numbers.

at i = 0 we get -0.5
i=-1 -> -0.75
i=-2 -> -0.875
i=-3 -> -0.9375
i=-4 -> -0.96875

And while this sequence is *not* mersenne numbers, mersenne numbers *are* in this set.

Just a curious discovery is all.

defuq!!
I was on the airport and wanted to buy a millefeuilles to eat, those bustards buy the single piece fir almost $2.5 (few meters outside the airport it's just less that $0.5).
Let's do the math: the dimensions of one piece is almost 10x5 cm, which means a surface of 50 cm² (0.005 m²).
So a m² of millefeuilles costs $500, what the shit, a m² awful millefeuilles is more expensive than m² of land in a respectable area.

I see a lot of talk about complex numbers, and yet
for all they are worth, I have not once been
able to find an explaination on how to calculate
them by hand, namely the real component.
For example
(-5)**0.5
(1.3691967456605067e-16+2.23606797749979j)

2.23606 is obviously just the square root of 5, but where the hell did 1.369 come from?

Apparently no one fucking knows, and no site I've found gives a simple explanation for someone new to math in general.

"use a calculator", "hit a button",

How about no.

Working on an Android app for a client who has a dev team that is developing a web app in with ember js / rails. These folks are "in charge" of the endpoints our app needs to function. Now as a native developer, I'm not a hater of a web apps way of doing things but with this particular app their dev teams seems to think that all programming languages can parse json as dynamically as javascript...

Exhibit A:

- Sample Endpoint Documentation
* GetImportantInfo
* Params: $id // id of info to get details of
* Endpoint: get-info/$id
* Method: GET
* Entity Return {SampleInfoModel}

- Example API calls in desktop REST client
* get-info/1
- response
{
"a" : 0,
"b" : false,
"c" : null
}
* get-info/2
- response
{
"a" : [null, "random date stamp"],
"b" : 3.14,
"c" : {
"z" : false,
"y" : 0.5
}
}
* get-info/3
- response
{
"a" : "false" // yes as a string
"b" : "yellow"
"c" : 1.75
}

Look, I get that js and ruby have dynamic types and a string can become a float can become a Boolean can become a cat can become an anvil. But that mess is very difficult to parse and make sense of in a stack that relies on static types.

After writing a million switch statements with cases like "is Float" or "is String" from kotlin's Any type // alias for java.Object, I throw my hands in the air and tell my boss we need to get on the phone with these folks. He agrees and we schedules a day that their main developer can come to our shop to "show us the ropes".

So the day comes and this guy shows up with his mac book pro and skinny jeans. We begin showing him the different data types coming back and explain how its bad for performance and can lead to bugs in the future if the model structure changes between different call params. He matter of factually has an epiphany and exclaims "OHHHHHH! I got you covered dawg!" and begins click clacking on his laptop to make sense of it all. We decide not to disturb him any more so he can keep working.

3 hours goes by...

He burst out of our conference room shouting "I am the greatest coder in the world! There's no problem I can't solve! Test it now!"

Weary, we begin testing the endpoints in our REST clients....

His magic fix, every single response is a quoted string of json:

example:
- old response
{
"foo" : "bar"
}
- new "improved" response
"{ \"foo\" : \"bar\" }"

smh....

Hey, I need ideas. Keywords: DIY, IT cabinet, cooling. I hope I'll catch your eye :)

So I'm doing my apartment renovation. Complete renovation, 100% everything is remade. Soviets did a lot wrongs but one thing they did I like - storage compartments below ceiling (like double ceiling.. does it have a name in English? I often see them in garages). So I tore down the old compartment and created a bigger new one. I've moved some of my IT devices up there: router, switch, raspberry, etc. Now... it's okay while it's autumn-winter, it's bearable up there. I'm worried temperatures might get very high during summer.

Compartment is not that big, smth 1m x 2 m x 0.5 m.

Any ideas for cooling? I could set up a vent fan to circulate air but it's hardly a cooling. Also not very effective. A/C is not an option as the compartment is too far away from outter walls. Also A/C might be somewhat overkill :) 5 minutes ago I've remembered I had an in-car portable fridge-like thing that could keep drinks decently cooled during summer. I'm wondering whether it would work? Any ideas where could I get this cooling mechanism (what to even google for? :) )?

Is there anything better in the market? DIY? I'm not willing to spend a fortune for this idea (one more reason A/C is an overkill)

Started working on a per project in Rust (first time using Rust) .. a scripting language.

Rust is great, so fast, compiles in 0.5-1.2seconds on my $200 laptop as well! Pretty rare for safety, speed, AND compile speed to exist in one beautiful language.

Also my scripting language is the opposite of beautiful. Oh God.

Piddling, and trying to learn some game stuff. Very simple game stuff.
Example code:

if (level % 10 === 0...) {
speed += 0.3;
...
} else if (level % 5 === 0...) {
speed += 0.1;
...
}

But because Javascript, console log reads:
speed: 0.5 <-- this is the initial console log
speed: 0.6
speed: 0.8999999999999999
speed: 0.9999999999999999

Well done Javascript, well done.

Should array indexes begin with 0 or with 1?

To end this discussion I propose they begin with 0.5.

Sooooo the computers at my university

printf("%f", 0.5);
Prints the biggest number a double can have, just... WHY!

heres something interesting:
The golden ratio is 1.618...

If you're not familiar with it, doing 1/goldenratio
the result is 0.618...
It gives you back the float component exactly.

Discovered that it is actually part of a series.

First of all:
2-(((5-sqrt(5))/2)-1) =
1.618033988749895 -> thats our golden ratio

In other words:
(2%gold) =
0.381966011250106

While:
((5-sqrt(5))/2) =
1.381966011250105

Ok, now we're getting somewhere. We can turn these into variables

First of all, lets see if we can get the golden ratio back out:
2-(((5-sqrt(5))/2)-1) = 1.618033988749895

Okay good.

The formula looks something like
j-(((i-sqrt(i))/2)-1)

Where j = (i*2)+1
That means we can easily figure out what j we need from our i value. (i-1)/2 = j

We run it back far enough we get
1-(((3-sqrt(3))/2)-1) =
1.3660254037844386

Thats the golden ratios little brother. Doesn't look anything like it, but it is part of the series.
And I found a boat load of research documents scattered *all* over the net, where this number and others in the series inexplicably crop up in power series, in chemistry, and elsewhere. Just looks like random floats if you don't know better.

We can actually go lower in the series:
0.5-(((2-sqrt(2))/2)-1)
1.2071067811865475

At the lowest positive value for j, we get
0-(((1-sqrt(1))/2)-1) = 1

It's kinda elegant.

I even wrote a little script to do the conversions:
def gr(k):
....i = k
....j = (i-1)/2
....return j-(((i-sqrt(abs(i)))/2)-1)

The dots are so devrant doesn't break pythons formatting.

My sister-in-law is a real fucking piece of work. My wife and I pay her to watch our daughter, who is 1.5 years old. She lives with us practically rent free (less than 0.5 of what she was having to pay in rent at her previous living situation). And as of late, my wife and I have been going through rough marital issues. Our marriage counsellor advised as ‘homework’ to write down a few things that would make us happy; individually of our partner, in our relationship.

Something I put down was, ‘that I want our daughter to be more mentally stimulated’ since she’s curious and inquisitive as fucking hell right now. And that I wanted us to find child care that would nurture her more than my sister-in-law does.

(She sits our daughter and one other little girl she watches down in the front room to watch the disney channel all day long. Sometimes she’ll talk to her friends for a few hours throughout the day on the phone. And makes them lunch and snacks when they are hungry.)

I’ve been looking into a daycare center that specializes in teaching kids early reading and writing along with a program that starts at 2 to focus on dancing or on music. They only want like $75 more per week and food and snacks are included in the weekly cost.

That being said I had written down my things for my ‘homework’ assignment. My daughter ended up getting a hold of it and brought it to my sister-in-law who now has a major attitude about this whole thing...

:side note:
My wife and I were struggling financially a bit earlier in the year and she helped us with gas money a few times and helped with some basic groceries and stuff. But today she just threw all of that ‘help’ back into my face.

If I had fucking known that you were going to hold that shit over my head and weaponize it against me because you feel hurt by the fact that you are a shit child care provider in my eyes then you can go smoke a fucking tailpipe you cum guzzling gutter slut!

Once a guy was not able to apply for a software company coz it required 4+ years of experience in a particular API.

The problem was that he had only 2 years of experience as he himself had developed that API. 😜

It's high time that we rethink the equation " Years of experience == Skill"

Do comment your opinion.

Messing with three.js library. Now imagine I have a letter in 3D, from which I removed all the faces and replaced vertices with white dots (plexus effect), and all around are like thousands of dots. Now I wanted to put single sprite somewhere on that letter. So I wrote a short script doing that. Fast forward an hour. I am figuring out, why the FPS significantly dropped to like 0.5 fps or what. Checking various browsers, even downscaling image from 512x512 sprite to 64x64, checking whole stackoverflow why is just one fucking sprite causing a lot of trouble and such an fps drop. Trying everything except... I wrote that function inside loop rendering those thousands dots all around. Lol my computer almost catched in fire rendering that shit.

Must to say, in chrome it had 0.5fps, mozilla had around 15-20 fps which is A LOT better.

So I promised a post after work last night, discussing the new factorization technique.

As before, I use a method called decon() that takes any number, like 697 for example, and first breaks it down into the respective digits and magnitudes.

697 becomes -> 600, 90, and 7.

It then factors *those* to give a decomposition matrix that looks something like the following when printed out:

offset: 3, exp: [[Decimal('2'), Decimal('3')], [Decimal('3'), Decimal('1')], [Decimal('5'), Decimal('2')]]

offset: 2, exp: [[Decimal('2'), Decimal('1')], [Decimal('3'), Decimal('2')], [Decimal('5'), Decimal('1')]]

offset: 1, exp: [[Decimal('7'), Decimal('1')]]

Each entry is a pair of numbers representing a prime base and an exponent.

Now the idea was that, in theory, at each magnitude of a product, we could actually search through the *range* of the product of these exponents.

So for offset three (600) here, we're looking at

2^3 * 3 ^ 1 * 5 ^ 2.

But actually we're searching

2^3 * 3 ^ 1 * 5 ^ 2.
2^3 * 3 ^ 1 * 5 ^ 1
2^3 * 3 ^ 1 * 5 ^ 0
2^3 * 3 ^ 0 * 5 ^ 2.
2^3 * 3 ^ 1 * 5 ^ 1

etc..

On the basis that whatever it generates may be the digits of another magnitude in one of our target product's factors.

And the first optimization or filter we can apply is to notice that assuming our factors pq=n,
and where p <= q, it will always be more efficient to search for the digits of p (because its under n^0.5 or the square root), than the larger factor q.

So by implication we can filter out any product of this exponent search that is greater than the square root of n.

Writing this code was a bit of a headache because I had to deal with potentially very large lists of bases and exponents, so I couldn't just use loops within loops.

Instead I resorted to writing a three state state machine that 'counted down' across these exponents, and it just works.

And now, in practice this doesn't immediately give us anything useful. And I had hoped this would at least give us *upperbounds* to start our search from, for any particular digit of a product's factors at a given magnitude. So the 12 digit (or pick a magnitude out of a hat) of an example product might give us an upperbound on the 2's exponent for that same digit in our lowest factor q of n.

It didn't work out that way. Sometimes there would be 'inversions', where the exponent of a factor on a magnitude of n, would be *lower* than the exponent of that factor on the same digit of q.

But when I started tearing into examples and generating test data I started to see certain patterns emerge, and immediately I found a way to not just pin down these inversions, but get *tight* bounds on the 2's exponents in the corresponding digit for our product's factor itself. It was like the complications I initially saw actually became a means to *tighten* the bounds.

For example, for one particular semiprime n=pq, this was some of the data:

n - offset: 6, exp: [[Decimal('2'), Decimal('5')], [Decimal('5'), Decimal('5')]]

q - offset: 6, exp: [[Decimal('2'), Decimal('6')], [Decimal('3'), Decimal('1')], [Decimal('5'), Decimal('5')]]

It's almost like the base 3 exponent in [n:7] gives away the presence of 3^1 in [q:6], even
though theres no subsequent presence of 3^n in [n:6] itself.

And I found this rule held each time I tested it.

Other rules, not so much, and other rules still would fail in the presence of yet other rules, almost like a giant switchboard.

I immediately realized the implications: rules had precedence, acted predictable when in isolated instances, and changed in specific instances in combination with other rules.

This was ripe for a decision tree generated through random search.

Another product n=pq, with mroe data
q(4)
offset: 4, exp: [[Decimal('2'), Decimal('4')], [Decimal('5'), Decimal('3')]]

n(4)
offset: 4, exp: [[Decimal('2'), Decimal('3')], [Decimal('3'), Decimal('2')], [Decimal('5'), Decimal('3')]]

Suggesting that a nontrivial base 3 exponent (**2 rather than **1) suggests the exponent on the 2 in the relevant
digit of [n], is one less than the same base 2 digital exponent at the same digit on [q]

And so it was clear from the get go that this approach held promise.

From there I discovered a bunch more rules and made some observations.
The bulk of the patterns, regardless of how large the product grows, should be present in the smaller bases (some bound of primes, say the first dozen), because the bulk of exponents for the factorization of any magnitude of a number, overwhelming lean heavily in the lower prime bases.

It was if the entire vulnerability was hiding in plain sight for four+ years, and we'd been approaching factorization all wrong from the beginning, by trying to factor a number, and all its digits at all its magnitudes, all at once, when like addition or multiplication, factorization could be done piecemeal if we knew the patterns to look for.

I was writing a simple algorithm to simulate gravity. But when I tested it it produced wildly wrong results. I looked over my whole algorithm trying to find the error, but thought that the last bit, the final position update, must be fine.
I was wrong, some misplaced brackets were accidentally multiplying the position + 0.5 by the sum of the old & new velocity instead of adding the position to 0.5 those velocities.

I noticed that and fixed it, and now it runs pretty well.

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

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

Money + connections + luck >= success

Why?

MONEY:
You must have money to make more money.

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

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

Let's calculate this probability:

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

money + connections + luck >= success

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

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

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

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

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

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

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

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

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

Out of total: 8 possible combinations, n=8

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

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

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

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

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

Mathematically proven how life is pure trash

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

I really hate working with learning management systems (LMS).
I make training simulations for retail companies and some of these have the worst, backwards LMS's out there.
The providers who install and manage these LMSs for the companies always insist we make our training run inside their own environment, but we can't since it's a 3D training made in Unity that doesn't run well in a browser.

Luckily some of these are fine to figure out. Just a few API calls here and there for authorization and reporting progress, but some are an absolute nightmare.

Just now one of the providers provided me with a 2000 page documentation of all the functions of the LMS's API that our customer is using. All I need are like 5 pages that explain what URL to call with what data and the responses, but now I'm stuck spending days trying to find the 0.5% of this documentation that I need to communicate with their API.

And of course, the documentation is vague as all hell. minimal descriptions of what each endpoint does. Subjects names are super vague, as in do I look for course progress or lesson completion state. What the heck is a Learning Event, is it relevant to me?

And the errors in this document, too.
Bullet-point lists with duplicate items.
language errors everywhere.
Property lists where they copy-pasted the description of properties.
An entire EMPTY chapter, literally a page with only the chapter's title.

I just can't stand how these providers barely seem to know anything about the API of the LMS's they provide to customers.
(for clarity, the LMS is produced by some big tech company, it's installed and maintained by some 3rd party which is our main line of communication when rolling out trainings to these).

It always goes like: "Hey, we want to use your training." "Oh, that's great, we have our own, simple LMS where you can view your employee's progress." "Nah, we want to use our backwards LMS. Here's a giant manual about it's API, go figure it out!"
And then I'm left here tearing my hair out trying to figure out which 3 calls I need to send their API from the tons of extra stuff it can do which is completely unnecessary and being unable to rely on the provider because they lack the knowledge and have such thick skulls about the implementation of the LMS itself that they also seems completely unwilling to help to begin with!

Just another day at the office.

A home hosted build server for continuous integration is always crap and a blocker for everyone. If you don’t have 5(yes, five) full time admins/devops to support that, forget about building the infrastucture yourself. There are companies whose business is to provide CI as a service, why do you think you can beat them with your crappy Jenkins installation?

I’ve seen a 200 company failing with 2 people. I’ve seen another one completely failing, because the admins didn’t know what CI meant, and a small one failing with 0.5. The only place where it kind of worked used Gitlab.

If anyone has a moment.

Fucking jQuery in Polymer 0.5.

When polymer 0.5 was released, things seemed incredibly easy at first, but when you need to do some complex things, the abstraction layer provided by web components are not of much help. Babel wasn't there too, so I ended up using scope hacks to access event listeners (var self = this). Worse, I have to use jQuery because many of things are downright tedious or fucked up back then, including myself.

Now, React is here; No jQuery, no hacks, no web component polyfills, no unsolvable perf bugs, no scope hacks, no 10sec loading time, no regrets.

BSNL (Indian state run telco) offers 4GB data per day for 90 days at just INR 444 (around 7 USD). Sounds awesome right? But the catch is their network. It is so pathetic that you don't even get signal of you're inside a building. Even if you have full signal, data speed hardly reaches 0.5 Mbps.

I have an iot solutions company which has 0.5 millions hits per day just from 7 devices. It is on shared server and it bogs down every now and then. In future it is going to grow to 100 million hits.

What kind of cloud instance on aws should i use. Or is there any special hosting for iot devices.

Let's say I take a matrix of high entropy random numbers (call it matrix J), and encode a problem into those numbers (represented as some integers which in turn represent some operations and data).

And then I generate *another* high entropy random number matrix (call it matrix K). As I do this I measure the Pearson's correlation coefficient between J (before encoding the problem into it, call Jb), and K, and the correlation between J (after encoding, let's call it Ja) and K.

I stop at some predetermined satisfactory correlation level, let's say > 0.5 or < -0.5

I do this till Ja is highly correlated with some sample of K, and Jb's correlation with K is close to 0.

Would the random numbers in K then represent, in some way, the data/problem encoded in Ja? Or is it merely a correlation?

Keep in mind K has no direct connection to J, Ja, or Jb, we're only looking for a matrix of high entropy random numbers that indicated a correlation to J and its data.

I say "high entropy", it would be trivial to generate random numbers with a PRNG that are highly correlated simply by virtue of the algorithm that generated them.
