Managment...

Where do I start?

So I have a task they set to priority "P0 - drop everything". Okay, dropping everything, doing the thing.

It's 11 and I already had 3 calls and meeting...

GOD FUCKING DAMINT LET ME WORK ON THE THING
and please let me focus -_-.

Oh, oh, also, calls were like "hi, we have a really dumb question to you, we know we could sit down for 10 seconds and use so-called logic but calling you is easier." Oh and also whats the progress on this P4 task?

holly motherfu... eghm. I mean.. They really like to piss me off. Best part of call #2. I prompt them "hey, please message me on slack, it does not destroy my focus and allows me work more efficiently"
and response... "I prefer talking than typing"

POSTMORTEM

"4096 bit ~ 96 hours is what he said.

IDK why, but when he took the challenge, he posted that it'd take 36 hours"

As @cbsa wrote, and nitwhiz wrote "but the statement was that op's i3 did it in 11 hours. So there must be a result already, which can be verified?"

I added time because I was in the middle of a port involving ArbFloat so I could get arbitrary precision. I had a crude desmos graph doing projections on what I'd already factored in order to get an idea of how long it'd take to do larger
bit lengths

@p100sch speculated on the walked back time, and overstating the rig capabilities. Instead I spent a lot of time trying to get it 'just-so'.
Worse, because I had to resort to "Decimal" in python (and am currently experimenting with the same in Julia), both of which are immutable types, the GC was taking > 25% of the cpu time.

Performancewise, the numbers I cited in the actual thread, as of this time:
largest product factored was 32bit, 1855526741 * 2163967087, took 1116.111s in python.
Julia build used a slightly different method, & managed to factor a 27 bit number, 103147223 * 88789957 in 20.9s,
but this wasn't typical.

What surprised me was the variability. One bit length could take 100s or a couple thousand seconds even, and a product that was 1-2 bits longer could return a result in under a minute, sometimes in seconds.

This started cropping up, ironically, right after I posted the thread, whats a man to do?

So I started trying a bunch of things, some of which worked. Shameless as I am, I accepted the challenge. Things weren't perfect but it was going well enough. At that point I hadn't slept in 30~ hours so when I thought I had it I let it run and went to bed. 5 AM comes, I check the program. Still calculating, and way overshot. Fuuuuuuccc...
So here we are now and it's say to safe the worlds not gonna burn if I explain it seeing as it doesn't work, or at least only some of the time.

Others people, much smarter than me, mentioned it may be a means of finding more secure pairs, and maybe so, I'm not familiar enough to know.

For everyone that followed, commented, those who contributed, even the doubters who kept a sanity check on this without whom this would have been an even bigger embarassement, and the people with their pins and tactical dots, thanks.

So here it is.
A few assumptions first.
Assuming p = the product,
a = some prime,
b = another prime,
and r = a/b (where a is smaller than b)
w = 1/sqrt(p)
(also experimented with w = 1/sqrt(p)*2 but I kept overshooting my a very small margin)

x = a/p
y = b/p

1. for every two numbers, there is a ratio (r) that you can search for among the decimals, starting at 1.0, counting down. You can use this to find the original factors e.x. p*r=n, p/n=m (assuming the product has only two factors), instead of having to do a sieve.

2. You don't need the first number you find to be the precise value of a factor (we're doing floating point math), a large subset of decimal values for the value of a or b will naturally 'fall' into the value of a (or b) + some fractional number, which is lost. Some of you will object, "But if thats wrong, your result will be wrong!" but hear me out.

3. You round for the first factor 'found', and from there, you take the result and do p/a to get b. If 'a' is actually a factor of p, then mod(b, 1) == 0, and then naturally, a*b SHOULD equal p.
If not, you throw out both numbers, rinse and repeat.

Now I knew this this could be faster. Realized the finer the representation, the less important the fractional digits further right in the number were, it was just a matter of how much precision I could AFFORD to lose and still get an accurate result for r*p=a.

Fast forward, lot of experimentation, was hitting a lot of worst case time complexities, where the most significant digits had a bunch of zeroes in front of them so starting at 1.0 was a no go in many situations. Started looking and realized
I didn't NEED the ratio of a/b, I just needed the ratio of a to p.

Intuitively it made sense, but starting at 1.0 was blowing up the calculation time, and this made it so much worse.

I realized if I could start at r=1/sqrt(p) instead, and that because of certain properties, the fractional result of this, r, would ALWAYS be 1. close to one of the factors fractional value of n/p, and 2. it looked like it was guaranteed that r=1/sqrt(p) would ALWAYS be less than at least one of the primes, putting a bound on worst case.

The final result in executable pseudo code (python lol) looks something like the above variables plus

while w >= 0.0:
if (p / round(w*p)) % 1 == 0:
x = round(w*p)
y = p / round(w*p)
if x*y == p:
print("factors found!")
print(x)
print(y)
break
w = w + i

Still working but if anyone sees obvious problems I'd LOVE to hear about it.

So I'm back from vacation! It's my first day back, and I'm feeling refreshed and chipper, and motivated to get a bunch of things done quickly so I can slack off a bit later. It's a great plan.

First up: I need to finish up tiny thing from my previous ticket -- I had overlooked it in the description before. (I couldn't test this feature [push notifications] locally so I left it to QA to test while I was gone.)

It amounted to changing how we pull a due date out of the DB; some merchants use X, a couple use Y. Instead of hardcoding them, it would use a setting that admins can update on the fly.

Several methods deep, the current due date gets pulled indirectly from another class, so it's non-trivial to update; I start working through it.

But wait, if we're displaying a due date that differs from the date we're actually using internally, that's legit bad. So I investigate if I need to update the internals, too.

After awhile, I start to make lunch. I ask my boss if it's display-only (best case) and... no response. More investigating.

I start to make a late lunch. A wild sickness appears! Rush to bathroom; lose two turns.

I come back and get distracted by more investigating. I start to make an early dinner... and end up making dinner for my monster instead.

Boss responds, tells me it's just for display (yay!) and that we should use <macro resource feature> instead.

I talk to Mr. Product about which macros I should add; he doesn't respond.

I go back to making lunch-turn-dinner for myself; monster comes back and he's still hungry (as he never asks for more), so I make him dinner.

I check Slack again; Mr. Product still hasn't responded. I go back to making dinner.

Most of the way through cooking, I get a notification! Product says he's talking it through with my boss, who will update me on it. Okay fine. I finish making dinner and go eat.

No response from boss; I start looking through my next ticket.

No response from boss. I ping him and ask for an update, and he says "What are you talking about?" Apparently product never talked to bossmang =/ I ask him about the resources, and he says there's no need to create any more as the one I need already exists! Yay!

So my feature went from a large, complex refactor all the way down to a -1+2 diff. That's freaking amazing, and it only took the entire day!

I run the related specs, which take forever, then commit and push.

Push rejected; pull first! Fair, I have been gone for two weeks. I pull, and git complains about my .gitignore and some local changes. fine, whatever. Except I forgot I had my .gitignore ignored (skipped worktree). Finally figure that out, clean up my tree, and merge.

Time to run the specs again! Gems are out of date. Okay, I go run `bundle install` and ... Ruby is no longer installed? Turns out one of the changes was an upgrade to Ruby 2.5.8.

Alright, I run `rvm use ruby-2.5.8` and.... rvm: command not found. What. I inspect the errors from before and... ah! Someone's brain fell out and they installed rbenv instead of the expected rvm on my mac. Fine, time to figure it out. `rbenv which ruby`; error. `rbenv install --list`; skyscraper-long list that contains bloody everything EXCEPT 2.5.8! Literally 2.5 through 2.5.7 and then 2.6.0-dev. asjdfklasdjf

Then I remember before I left people on Slack made a big deal about upgrading Ruby, so I go looking. Dummy me forgot about the search feature for a painful ten minutes. :( Search found the upgrade instructions right away, ofc. I follow them, and... each step takes freaking forever. Meanwhile my children are having a yelling duet in the immediate background, punctuated with screams and banging toys on furniture.

Eventually (seriously like twenty-five minutes later) I make it through the list. I cd into my project directory and... I get an error message and I'm not in the project directory? what. Oh, it's a zsh thing. k, I work around that, and try to run my specs. Fail.

I need to update my gems; k. `bundle install` and... twenty minutes later... all done.

I go to run my specs and... RubyMine reports I'm using 2.5.4 instead of 2.5.8? That can't be right. `ruby --version` reports 2.5.8; `rbenv version` reports 2.5.8? Fuck it, I've fought with this long enough. Restarting fixes everything, right? So I restart. when my mac comes back to life, I try again; same issue. After fighting for another ten minutes, I find a version toggle in RubyMine's settings, and update it to 2.5.8. It indexes for five minutes. ugh.

Also! After the restart, this company-installed surveillance "security" runs and lags my computer to hell. Highest spec MacBook Pro and it takes 2-5 seconds just to switch between desktops!

I run specs again. Hey look! Missing dependency: no execjs. I can't run the specs.

Fuck. This. I'll just push and let the CI run specs for me.

I just don't care anymore. It's now 8pm and I've spent the past 11 hours on a -1+2 diff!

What a great first day back! Everything is just the way I left it.

This is kinda the silliest thing ever but...

In a class with a computer lab, one of the other people who uses the same desktop as me started taking screenshots at exactly 1:11. I followed suit and started taking screenshots at 11:11. I still have no idea who they are...

Now is almost the end of the year, and I really want to know who they are if only for the satisfaction, so I was thinking and came up with a solution that would take minimal social interaction. I wrote a Python script to take a screenshot every eight seconds and hid it on the computer, running. It saves the screenshots to a folder that is nested in another one, so the likelihood of someone finding out about this is pretty low. So anyways next class day I'm going to sift through the screenshots and find out who this is and probably some stuff about them given that I get to see over an hour of their computer activity. Fun stuff!

TL;DR I'm using Python to stalk kids at my school...

Well I choose nodejs and typescript because it was quick and easy to get started and finish a project with but nobody seems to care about that decision. Still get asked to work on react every 11 seconds of my life 💁🏼‍♀️

PM: this is our super fancy new CI/CD pipeline, it's the greatest. i expect you to learn and understand all this in no time.
devs: so i have to spend some more time on this topic because it's completely new to me and requires some learning...
PM: nooo, that's a super easy task with zero effort, my braindead hamster can do that in no time, so can i, and so can you! let's assign 1 story point for that.

~ 3 months latèr ~

also PM, after he has started developing as well: so i'm realizing there are many things that i have to learn, and it takes me some time. i haven't developed with C++ and <other tool stack> for a longer time. by the way, you guys don't need to check for any quality right now, we need to deliver fast. it's okay, when you have memory overflows, your code is completely crappy, poor architecture or memory overflows, it doesn't matter.

he even has a subtask for migrating his code from VS project to our new project structure, since he refused to learn our pipeline right from the beginning and created VS project instead. シ why is this a subtask? this job can be done in no time, my left vanishing twin named Klaus who has dislexia and hates vim can solve this task in 20 seconds!!!!11

(and still no PR, not even a feature branch in our repo)

Upgraded from a gen 6 motherboard and cpu to a gen 11. And the difference is asounding.

My old setup did everything I needed it to pretty well. Hell it got me through college as well as multiple part time and full time jobs. As well as the system that I learned about 80% of what I know specifically for my career

But alas the old cpu's age started showing and I'd consistently throttle multiple threads when compiling or even just using 7z on large folders. Hell deleting anything above a couple hundred mb would pause for a few seconds

The new cpu is immensely faster on such tasks (probably cause of the extra 2 cores and cpu improvements since gen 6)

I haven't been this excited since I got my first SSD a few years ago and saw the immense boot time improvements. Maybe soon I'll get an nvme drive and really be zooming with this setup 🤣🤣🤣

You can compile sass straight to c on a Mac instead of going to ruby first... I've wasted so much time. 11 seconds to compile --> .4 now 😑

I've just bought 3 months sky ticket...
THEY ONLY ALLOW A 4-DIGIT NUMBERS ONLY "PASSWORD"?!?!

IN WHAT YEAR DO THEY LIVE???

AND THEY EVEN SEND IT TO YOU VIA EMAIL ALONGSIDE YOU USERNAME!

I guess their old windows server which handles their authentication would be overcharged when it'd handle real passwords.

TL;DR: TIL for heavy queries use PDO and not some frameworks DB class

ffs I was trying to save 300k+ lines at once with Laravel for weeks. Mind you from a text file. 1gb ram on the vps so while trying to prepare the text to save: Fatal Error: Allowed Memory Size of bla bla Bytes Exhausted

ok so lets put it in a loop: Fatal error: Maximum execution time of 30 seconds exceeded (set_time_limit(0); lol)

optimising, varying the code got me into a situation when the content got saved in the BD but inconsistent (duplicates) and the table had often more than 1,5M rows. That was what told me its not a performance issue, my code is the issue. (dah)

I was starting to think it would be easier to export a prepared query to a sql file and load the file into the db as thats the fastest possible option...I even started to think about switching to python, then it hit me, Laravel has a shitload of routes to the DB so I switched to PDO

benchmark on 1vCPU, 1GB RAM VPS with SSD
379k lines with 11 columns in less than 10 sec with a loop of saving every ~6000 rows (if i tried choking it to save the whole thing at once it went up to 16-17sec)

Difference between 2023-01-01 00:00:00 and 2023-12-31 23:59:59 is 11 months, 29 days, 23 hours, 59 minutes, 59 seconds ; so almost a year (by one second)

Difference between 2023-01-01 00:00:00 and 2023-01-31 23:59:59 is the same, almost a month by 1 second.

Same for february (even with 28 being the last day).

But then, 2023-03-01 00:00:00 and 2023-03-31 23:59:59 gives me :
1 month, 2 days, 23 hours, 59 minutes, 59 seconds.

WHY, are there fucking 34 days in March ? Is this a bug ? Is it confused with February being the previous month ?
Why would PHP do this to me ?

Why the hell is it always so painful to work with dates, it's not even like I'm stretching the standard library or using raw timestamps to hack things together

I used the diff method of PHP 7.4 DateTime, is someone wants to try it

So I just installed Android 11 on my OnePlus 6T with the 18.0 release of LineageOS. Screen recorder built-in that can finally record system sound and play it too (there used to be a Magisk module but that couldn't play system sound while recording it, everything else is just through the mic) and some doodads like the selection for where to blast your music into has been moved more into view... Epic.

And then comes the Scoped Storage. Oh boy were the Android devs right to hate the guts out of it. It's so fucking slow. Seriously, on that exact device with Android 10, blazing fast. That storage is far from cooked. On Android 11.. have a directory with a thousand or so files, and it takes 5 goddamn seconds to open the directory with them in it. And even with external file managers that you give storage access like usual! Except when you root your device and use a root file manager, then it's fast again. Because that's using the shell instead.

I never thought I'd be able to say this to be honest. The shell is faster than the native tools. Let that sink in for a moment. The shell is faster than the native tools. How on Earth did Google think that this is tolerable?! For security, are you kidding me? Yeah I'll just use the root account for fucking everything in all that security, to have a functioning system!

Android 10 was also initially planned to have this terrible storage system, but due to developer backlash, Google waited a release and it was optional there. That wasn't just time for developers to adapt to Scoped Storage. That should've also been time for Google to actually make it usable.

Former android fan, I’ve been using iPhone SE for a while, and now I’m ready to give feedback. We are talking about brand new, iOS 11.2.2 device, never jailbraked (jailbroken?) or made anything fucked up to.

The main problem is battery life. It’s poor. I mean, my cheap ass Meizu m3s stands for about three times longer. Now I always need to carry power bank or charger around, keeping it up from one outlet to another.

iOS 11 is unstable and flawed. Music widget on lock screen freezes randomly, ui falls apart sometimes, apps sometimes start in landscape mode. I never found android ui falling apart, just like webpage marked up by interns.

Transferring files to Linux PC is huge pain in the ass. Nuff said.

Aaaand... that’s all. There is literally only three problems present.

On the other hand, there is huge advantages over android:

Speed. It’s unbeatable. It’s absolutely stunning. Need camera? Here it is, quarter second away. Android camera needed straight 15 seconds to start up. Taking picture? Here it is, flawless as always. Zero motion blur, gamma is ideal, focus is so sharp so you may hurt your eyes. Need 100 pictures? Here you go, just press the button and hold it. Maybe s9 or another shiny ass android takes pictures as fast as iPhone, but I bet my iPhone will be taking pictures same flawlessly after 5 years, while your android will probably become sluggish ass piece of crap.

Not. A. Single. Fucking. Lag.

Asphalt 8? 60 FPS all the way down. 2GIS? Fraction of a second away. That’s it, that’s how it have to be.

Sound quality. Just as neat as my Sansa Clip. EarPods are crap, so I’m using my SE215. Not going to ever come back to Sansa. Xperia TX had much less quality audio btw.

Apps. As long as the whole enterprise world sucking Apple’s dick, apps are running silky smooth and the things are not going to change. Come on. Apple is the king nowadays, admit it or not.

Keyboard is amazing. Screen is amazing. It’s just that pleasing. The sounds iPhone makes are great, while android sounds piss me off and making me hold myself from throwing the phone straight to the wall.

iPhone makes me feel cared about. Everything is on it’s place, everything fits perfectly. You are watching YouTube, you need to adjust volume and volume bar appears as tiny strip on the very top, just to not distract you. Make screenshot, draw something on it, share and hit delete. Every action you need is one tap away. Look up word? One tap away. Position the cursor between words? Polished as fuck, here you go, have your handy magnifying glass. Adblock in safari? Install it from the App Store and it will be literally two taps away, right at the settings. No VPN needed. Safari doesn’t become slow with Adblock, it’s just the same amazingly fast browser, but without ads. And Apple Music is just one dollar a month for students, filled with high quality songs.

Even google apps working better on iOS.

The advantages are clear for me, while downsides aren’t significant. @irene, you wanted to know what I’ll tell after a while, so I’m saying it proudly:

I’m never ever coming back to android.

I don’t understand why people hate windows, especially windows 11??

Running Windows 11 on a Dell Latitude 3520 with an 11th Gen Intel Core i5 processor, I was able to go from the computer completely shutdown to a new 3D unity project fully loaded and ready to go in only 1 minute and 25 seconds!!! That’s from completely shutdown!

I haven’t overclocked the PC or anything and have used half of the 465GB storage!

I always rant about Ubuntu but today I'm gonna be fair, I had a 30 seconds look at the new Windows 11 user interface: is a so fucked up guresome mess, with its center-aligned taskbar, rounded windows corners and recent docs section taking up half of the center-aligned start menu, that it makes me want to puke before the entrance of the closest Microsoft's company building. And you now what? Such building is actually not farther than 20 minutes from where I live, so I probably will.

#NIPS2018 The main conference sold out in 11 minutes 38 seconds

AI conferences are like concerts these days, haha

While fucking my hot blonde gf this morning the Fucking DUREX condom BROKE and i creampied her. Here are the reasons why its not my fault:

1--Im not retarded

- 4 years of fcking my hot blonde gf with no protection and nothing ever happened cos im !retarded. Its a bigger risk to fuck with condom than without, how is this fucking normal???

2--I use condom the right way

- i was holding the tip so air comes out, just like it was explained on the box, but while rolling it down i was still holding the tip to make sure the air doesnt come back up

3--She was wet

- she wasnt dry. My hot blonde gfs pussy was so wet from how horny she was so its impossible that it got torn due to dryness

4--First verification

- it wasnt torn or ripped. It was normal. Everything looked absolutely fine

5--Second verification

- when i put it inside my hot blonde gf and fk her i pull it out in the first 10 seconds just to make sure it isnt torn--it was good and nothing was ripped so i slowly put it back inside

6--Condom is not thin

- i took the regular durex one (fuck this fucking dead fraud company I'll piss and shit on their grave) so it wasnt the thin bullshit one

7--Dont got a big black dick

- its normal. Average. Not small nor big. So latex elasticity isn't my problem

8--50-50%

- every FUcking time when i fked my hot blonde gf with a condom i always stressed if it'll break or not. This is not the first time it broke. FUCK the product that is THIS MUCH unreliable, unsafe and fragile! I'll fuck the whole durex company up. Im not the only one who had this problem. DUREX IS THE BIGGEST OVERRATED SCAM COMPANY SPENDING BILLIONS ON MARKETING FOR A LOW QUALITY SHIT PRODUCT THAT DOESNT EVEN WORK

9--Package didnt expire

- i bought a new box in the store on 8th march for womens day (modern women value having gifted with condoms more than flowers). It wasnt bought in a shit china quality shop. I fked her in the car at night and also creampied her but the condom did NOT break. Then i fked her this morning in bed with condom from the SAME BOX, and now it DID break. Are you Fucking kidding me???

10--Emergency contraception

- i died from high adrenaline of running so fast to the store to buy her contraception. Had to run to 4 fucking stores cause all of them don't work before 7:30am. Finally found one in the 4th store and she drank Escapelle within 20 minutes of incident, as soon as it was physically possible

11--And now what

- now what. What do i do. I did everything i could. Nothing is my fault. My hot blonde gf wanted me to creampied her it was her idea so shes at fault partially. She will get tested in 15 days while this contraception lasts. Dont know what else to try. This bullshit never happened before
