Her: Why do you need 3 monitors??
Me: Why do you need 6 bags on the hanger, permanently, and 23 pairs of shoes?
Her: :/

Her: why did you buy a computer that costs 2.5K
Me: Why do you buy multiple pairs of shoes that costs 1K+

So, I was participating in a competition, but little did I know that you could only participate in pairs. Seeing that a lot of famous indie devs were participating I was extremely hyped. But since it seemed like I was the only idiot who didn't have a partner I felt like kicking myself. Then a guy about whom I had never heard of before, probably a newbie, comes out of the blue and asks me to be his partner. Since I had no choice, I reluctantly agreed to pair up with him. The rules of the competition were to create a game based on a particular theme in a period of 1 week. To get started, I asked him about his skills as it would be better to know what our strengths and weaknesses were. He said that he was good at art and proceeded to show me some of his "previous works". I was genuinely impressed. Honestly speaking his drawing seemed a bit off but was but for a newbie, it was good. So we decided that he would take care of the art and I would code, create some basic music (nothing too fancy because of the lack of time) and if time permits, refine his art(correcting ratios, colour combinations, shading, etc.). On the first day, he would like to work in privacy and would show only the finished products to me. It seemed a bit fishy, but hey, I am all up for respecting the wishes of fellow team members.
So all was going well, or so I thought, till on the fifth day the guy confesses that he didn't get shit done. Apparently, his "previous works" were random stuff taken from the great land of internet and that he had to leave town the next day. He just wanted to "experience the life of a game developer" and "meant no harm". I flipped out, half lectured half screamed at him then asked him to get the fuck out which happened to be the only fucking thing that he was able to do correctly. I thought for an hour or so, then contacted the staff and informed them about my situation. They said that if I was okay with the handicap, I may continue. I then pulled three all nighters with about 3 hours of sleep (that too in parts of about 1 hour) everyday and was barely able to submit my game on time.
I secured the fifth place, which was pretty good if I may say so myself, but it an important lesson in my life that taught me to never trust anyone blindly.

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.

There’s a junior on my team, who has an ego problem.

Within 6-8 months, they have not progressed much, up to the point they still struggle with language and framework syntax.

Yet, they want to get the credit for doing big and important tasks, the ones they have no clue at all how to execute.

Our team tried to break more the tasks and tickets almost to the point of a tutorial. Junior got upset and complained that they did not want the tasks to be broken for them.

If we give space, tasks take forever to get completed. If we try to pair, Junior does everything in their power to cut the meeting short and again take forever to complete anything.

If we prioritize our own tasks, Junior complains that nobody pairs/assist them.

Took one for the team and started to work on finding ways to get this wonderful person to learn. Junior does not learn. In fact, almost feels like things enter from one ear and leave from the other instantly. Despite being repeated multiple times. Chewed. Presented in all sorts of way. You name it, I’ve tried.

Yesterday was the last drop. They fucking rolled their eyes while was explaining something.

This person is dead for me and I will make my personal crusade to not go out of my tasks to help them.

Thanks for coming to my TED rant.

Allright, I'm pissed.

-- Background --
In an attempt to reorganize my desktop I accidentally deleted a folder I called "development". In there I stored links to all my IDEs (Not sure how you call these in english), but also some workspaces like unity (Not much stuff there, processing (just some hobby stuff) AND Eclipse (FUCKING EVERYTHING RELATED TO SCHOOL WEB DEVELOPMENT). Now 3 days have passed and I realized this important folder was missing. Cleared that windows trash the instant I deleted the trash on my desktop.

> Shit, Regret

Install a file restore programm. Do every possible search. Nothing found.

> Big shit

Deadline was in like 3 days. Week was fucking rough so:
> "Screw this, the teacher nevet corrects the assignments and also fuck JSP"

Fast forward 2 months to last week. Teacher starts checking assignments.

> Fuck

* Sees pattern: Only students with missing or bad marks are checked. *

* Feels save *

Teacher approaching me while working on current projects.
* Doesn't feel save anymore *
> "Well, I'ld like to see your THAT programm"
> Well fuck
* Tells the truth *
> "Well that's unfortunate, but I must write a mark. Do you really have nothing to show?"
* Remember that I worked on the school pcs when I started *
> (Better than nothing. Gotta try it)
* Teacher checks programm, not pleased *

> (Fuck me, but at least it's over...)

> Nope

* Teacher calls me over *
> "With the mark I had to write today you can't reach that good mark even with a good examination, what are we gonna do about this?"

> "Well, there were other assignments that were never checked. Could we replace that mark with one of those?"

* Teacher agrees *

My best choice was an Android app we had to develop during December in pairs. I did the front end (90% of the whole work) and my partner the backend (10 %). I also did 30 % of these 10 %, because I had to review the shit he wasn't able to debug himself.

> brainlogic.exe provided by windows vista

This distribution was partly my fault since I overestimated the work needed for the backend, but also the fault of that fucker. I mean, he didn't tell me the professor already provided 90 % of the backend...

Rest of the week was really busy (always 1 or 2 things to study for each day, workout and family stuff).

Yesterday (It's past 12 already) I arrived at ~9 pm in the dorm I could finally start reviewing my code.
Internet gets shut down at 10 pm.
Gotta hurry.

* Opens project *
* Sees half a year old code *
* Fights urge to puke *
> (Alright I gotta do this. For the mark!)
* waits for gradle to index files *
* Remembers the fact that I haven't opened Android Studio in the last 2 months *

For those who don't develop with android studio: This is an equivalent to ~10k windows updates waiting to be installed

> (Well, gotta work with this kinda old version)

"gradle sync failed"
> ( Ok, just restart it. You're fine )
* Android Studio doesn't react anymore and/or renders *
* Waits 5 min *
* Restarts laptop *
* Android Studio is reacting again*
"gradle is synching"
9:45 pm: gradle is done and I can finally compile my app

> FML

* Sees App launched on phone *
* Almost pukes again *

> (This was the assigment for the UX chapter, so design doesn't matter)

UX is decent. Proceeds with testing stuff. Save paths work, but some bugs can be caused by going of it

* fixes as much as possible *

* Takes quick look at backend *

Date date = new Date (GregorianCalender.getInstance().getTimeInMillis());

C'mon, I asked you to be the backend. You got 90% of the methods already written by the teacher and had 2 months to write the interfaces to my Front end AND you come up with shits like that.

Note: this example is a minor example of brainlogic.exe

I did what I could to make improve my situation. Hopefully he doesn't discover the bugs. And If it's a backend bug then I could't care less, since that was not my job!

Wish me luck for today!

This probably isn't the coolest bug I've ever solved, but surely the one with the biggest faceplam
So I was building a Bluetooth smart watch that pairs with your Android device for the final year bachelor's project. The submission was in a 2 days and it was all ready and it suddenly stopped working.. Spent hours trying to fix it, even tried to get a replacement Bluetooth module (was out of stock -_-).. After a day's worth of freaking out I discovered that Android phones (at least the OnePlus X) don't connect to Bluetooth modules when their battery is below 15% -_- and since I was freaking out I would let the phone charge a bit and get back to debugging and it never crossed 15% so it never worked.. One day of debugging attempts later it suddenly struck me that low battery might be an issue.. And voila! It worked after charging the phone

Shouldn't such things be clearly mentioned in documentation :/

(Btw, got full for the project, got a 10/10 GPA for the semester)

SICK AND TIRED OF READABILITY VS. EFFICIENCY!!!!!!!

I HAD TO SEPARATE A 4 LOC JSON STRING, WHICH HAD AN ARRAY OF A SINGLE KEY-VALUE PAIRS (TOTAL OF 10 OBJECTS IN THE ARRAY).

ITS READABLE IF YOU KNOW JSON. HOW HARD IS TO READ JSON FORMAT IF YOU GET YOUR STYLE AND INDENTATION PROPERLY?!?

SO I HAD TO
BREAK THE POOR FREAKING JSON APART TO A FUCKING DIFFERENT YAML FILE FORMAT ONLY SO I CAN CALL IT FROM THERE TO THE MAIN CONTROLLER, ITERATE AND MANIPULATE ALL THE ID AND VALUES FROM YAML BACK TO MATCH THE EXPECTED JSON RESPONSE IN THE FRONT END.

THE WHOLE PROCESS TOOK ME ABOUT 15 MINUTES BUT STILL, THE FUCKING PRINCIPLE DRIVES ME INSANE.

WHY THE FUCK SHOULD I WASTE TIME AT AN ALREADY WORKING PIECE OF CODE, TO MAKE IT LESS EFFICIENT AND A SLIGHTLY BIT MORE READABLE?!? FML.

I just read a rant about Java by a guy who moved from JS/python.
FFS, until now you were using some aberration of OOP by creating "objects" and making them however you want instead of sticking to concept of blueprinting and managing your classes in a way shit happens properly.
Yes, I do hate js/python-like langs if I would have to do something big in them, because I need to constraint my program so it works predictably every time. I don't feel like I'm doing that by putting some arbitrary key-value pairs into some random object :v
Java and her sexier sister Kotlin ftw and nothing gonna change my mind <3

If anyone has been keeping up with my data warehouse from hell stories, we're reaching the climax. Today I reached my breaking point and wrote a strongly worder email about the situation. I detailed 3 separate cases of violated referential integrity (this warehouse has no constraints) and a field pulling from THE WRONG FLIPPING TABLE. Each instance was detailed with the lying ER diagram, highlighted the violating key pairs, the dangers they posed, and how to fix it. Note that this is a financial document; a financial document with nondeterministic behavior because the previous contractors' laziness. I feel like the flipping harbinger of doom with a cardboard sign saying "the end is near" and keep having to self-validate that if I was to change anything about this code, **financial numbers would change**, names would swap, description codes would change, and because they're edge cases in a giant dataset, they'll be hard to find. My email included SQL queries returning values where integrity is violated 15+ times. There's legacy data just shoved in ignoring all constraints. There are misspellings where a new one was made instead of updating, leaving the pk the same.

Now I'd just put sorting and other algos, but the data is processed by a crystal report. It has no debugger. No analysis tools. 11 subreports. The thing takes an hour to run and 77k queries to the oracle backend. It's one of the most disgusting infrastructures I've ever seen. There's no other solution to this but to either move to a general programming language or get the contractor to fix the data warehouse. I feel like I've gotten nowhere trying to debug this for 2 months. Now that I've reached what's probably the root issue, the office beaucracy is resisting the idea of throwing out the fire hazard and keeping the good parts. The upper management wants to just install sprinklers, and I'm losing it.

PSA to /[devs who things it's a good idea|management who thinks it's a good idea to force your devs]+/g:

There currently exists 1543 (and counting) top level domains. My email addresses follow the pattern: /^[a-z]+@panduro\.guru$/ and I die a little inside whenever I get told my email addresses aren't valid because you thought it was a good idea (to force your devs) to hardcode "valid" top level domains. There is a reason why the filter for input type email does not include top level domains.

And you can't even begin to comprehend how mildly annoyed I get when I message their support and tell them what the problem is (because I'm nice enough to do that) they instead of telling me "thanks for informing us we'll look into it" they tell me "well just get a gmail or something". I should not have to order social status reducing items with my school mail (especially not since I'll loose that email ¾ pairs of years)

Motivating and helping each other by forming small teams/pairs of devs who look after each other. No one likes to code alone

As you can see from the screenshot, its working.
The system is actually learning the associations between the digit sequence of semiprime hidden variables and known variables.

Training loss and value loss are super high at the moment and I'm using an absurdly small training set (10k sequence pairs). I'm running on the assumption that there is a very strong correlation between the structures (and that it isn't just all ephemeral).

This initial run is just to see if training an machine learning model is a viable approach.

Won't know for a while. Training loss could get very low (thats a good thing, indicating actual learning), only for it to spike later on, and if it does, I won't know if the sample size is too small, or if I need to do more training, or if the problem is actually intractable.

If or when that happens I'll experiment with different configurations like batch sizes, and more epochs, as well as upping the training set incrementally.

Either case, once the initial model is trained, I need to test it on samples never seen before (products I want to factor) and see if it generates some or all of the digits needed for rapid factorization.

Even partial digits would be a success here.
And I expect to create multiple training sets for each semiprime product and its unknown internal variables versus deriable known variables. The intersections of the sets, and what digits they have in common might be the best shot available for factorizing very large numbers in this approach.

Regardless, once I see that the model works at the small scale, the next step will be to increase the scope of the training data, and begin building out the distributed training platform so I can cut down the training time on a larger model.

I also want to train on random products of very large primes, just for variety and see what happens with that. But everything appears to be working. Working way better than I expected.

The model is running and learning to factorize primes from the set of identities I've been exploring for the last three fucking years.

Feels like things are paying off finally.

Will post updates specifically to this rant as they come. Probably once a day.

am i missing anything?

Fuck my country's universities, fucking greedy assholes that ruin lives, suck wallets and sucks life from the young.

I'm currently studying something completely non related to programming: History. And I really love it. I love reading 1000 pages for each test and essay and talking about the problem of naming the Cold War a war and cold and etc. The problem is that I won't make as much money as I would make even as a self taught developer.

After considering my possibilities, I thought I could enter the computer science carreer. I don't know how this works in other countries but here you would have to study 3 years of an engineering common plan and then specialise in some sort of industrial engineering while getting an specialisation also in computer science. After some counting, I got to the conclusion that I would be studying 6 years (or more), and wasting half of those years learning stuff that I would never use nor care about.

But that's not all. This semester I took the introductory class for programming. It's pretty basic stuff but at least they teach a little bit about algorithms and problem solving. It turns out that a friend of mine that's about to graduate from computer science applied as a helper for the prof. I was so excited I could finally talk with someone about code!

Since the start of the semester I have been passing a lot of time with him and talking about the future. Turns out he doesn't understand shit about code but somehow he learns everything by hard and has passed every computer science course without having any practical abilities. I don't blame him, he's studying hard and playing by the rules, and turns out that he has wasted precious time of his life also learning biology, chemistry, structural engineering, hidraulic engineering, transportation engineering and a ton of engineerings that he won't use.

If the university would instead take that time to teach better courses of practical programming or leave him some time to try out the stuff he learns by hard, he wouldn't have to hear me talking about stuff he doesn't comprehend but feels that should, and wouldn't be utterly depressed, he wouldn't take SIX years to learn less than what he could learn in less than THREE years. And this isn't just a random university, it is one of the 2 best universities we have here and was in 2014 the best of all Latin America.

And wait, here comes the best part. In my country, levels of education are heavily stratified. After school, superior studies give different titles according to the time you've been studying. Yes just the time. And these titles are what your employers will see to give you different work positions. So for studying a 2 year carreer you get a technic job which pays well but not too well, then at 4 years you get a license title which only proves that you know stuff, then at 5 or more (depending on what you are studying) you get a professional degree and will get payed as a full fledged professional. So here, even though in other countries it takes 6 years to have a masters in engineering, they give you just the engineering degree, and it would take 2 (or more) more years to have a master. Even though you can totally teach engineering in 4 years, here they take BY LAW 2 years more, while paying what a fucking full stack of pairs of kidneys would cost in the black market.

So fuck that shit, I won't be throwing my money at any university. I hope they get reformed soon becouse this is fucking dumb, really really dumb. Like 2 year old shit dumb. I'll just learn a bit more, make some projects until I have a decent portfolio and apply to some company that cares for real knowledge and not just a piece of paper with letters and a shitty logo on it.

“We mob every thing so that means we don’t need pull requests, because by the time the code is committed it’s had plenty of pairs of eyes on it”

Well, I beg to differ.
Today I read through some of this spaghetti mobbed code to look into a performance issue. Wasn’t supposed to but bored stiff so I ‘went dark’ and did it without the mob.

After about an hour I figured out it runs a few lines of dubious code and if there’s an error it tries many times over with an exponential back off.
And each run of the methods will fail for sure because of how it’s written.
Someone must’ve seen this problem but instead of realising it can never work, they’ve wrapped it in retries and back offs.

So many back offs and retries that it just sits there doing this for 25 minutes.

But yeah. The mobbing works great guys, keep churning out this quality code. 😂😂😂
Can’t wait to see the back of this joke job.

Here is a list of technologies that I hate.

Printers:
Can we not make a printer that isn't a POS? We've been making them for years and they still suck.

Bluetooth:
It is supposed to be convenient, but it never pairs when you want it to. It is always when you are driving and dont have time to mess with it that it doesn't work.

Bluetooth Printers:
See above for details.

Routers:
Can we not make a router that lasts longer than a year?

Oh dude and fucking self serve checkouts. Fuck that shit.

They always spawn in pairs

Arghhhh.

So I'm working alongside a very big development house that specialises in vehicle finance. They are huge - 60 plus developers, only work in pairs, have a minimum fee of £2500 per day and work with all the largest car manufacturers.

However, today they decided to completely change their api sub domain and all api routes that handle finance quotes. No warning at.

Of course sites I'm working on that consume this consume the said api are broken too.

To make things worse, my client pYs this company circa £19000 per year to use their api. I also recently discovered that the client is paying for their so called managed service. Insanity.

I mean seriously. This company has 4 layers of project manager and 3 forms of a senior developer. According to companies house their turnover is in excess of £4 million per year.

However, they get the basics wrong and do not warn in advance of major changes to their core api service.

Off I go to deal with 10 of project manAgers and support people in the hope if speaking to someone who can actually help.

An anti-rant: I just made some code and out of nowhere it suddenly had an awesome feature that I didn't even program. No, not a euphemism for "bug", an actual feature.

Here's the story: A few months ago I made a shortcut for "System.out.println(…)" called "print(…)". Then I developed it further to also print arrays as "[1,2,3]", lists as "{1,2,3}", work with nested arrays and lists and accept multiple arguments.
Today I wanted to expand the list printing feature, which previously only worked for ArrayLists, to all types of List. That caused a few problems, but eventually I got it to work. Then I also wanted to expand it to all instances of Collection. As a first step, I replaced the two references to "List" with "Collection" and magically, no error message. So I tested it with this code:

HashMap<Integer, String> map = new HashMap<>();
map.put(1, "1");
map.put(2, "");
map.put(3, "a");
print(map);

And magic happened! The output was:

{1=1, 2=, 3=a}

That's awesome! I didn't even think yet about how I wanted to display key-value pairs, but Java already gave me the perfect solution. Now the next puzzle is where the space after the comma comes from, because I didn't program that in either.

I feel a bit like a character in "The subtle knife", who writes a barebones program to communicate with sentient elementary particles (believe me, it makes sense in context) and suddenly there's text alignment on the left and right, without that character having programmed any alignment.

So I'm on my morning stroll. Walking, enjoying, watching the world around me.. It's nice how cherries blossom. They smell very tempting to stop there and enjoy the moment. Some flowers under the cherry...

Why do plants blossom again? Oh yeah, that's right, to exchange some speciments in order to grow fruit and seeds. To have their offspring. Just like every other living macroorganism [with a few exceptions ofc]. Life has no other way to survive but to exchange genetic material between two parties and only then trigger growth of the new life.

And that is a very strict rule. No more, no less: it takes exactly 2 organisms to make new life. But why is that? If my memory serves, theory of evolution says that life is like business: cut the losses and let the profits run. Over time it discards everything not required for the organism in order to save energy, and only successful new "investments" remain in the genome. The unsuccessful ones die before they proliferate, so the bad genes shall not survive.

It also says that very simple things, very simple changes lead to very complex outcomes. Us. Life.

But what is simple about life having to need 2 other lives? Exactly 2. It's either simple or efficient, depends on perspective. BUT IT IS NOT BOTH. Look at cells. They just split in half and multiply. Dead simple. It takes one of them to make another one. But with mammals, birds, reptiles, plants and other macroorganisms [excpt fungi] this is not the case! Why?!? I can't think of any scenario where two generic microorganisms, following some dead simple mutations, would come up w/ something that inefficient and overly complex. Like they're living on their own, multiplying by division, and smth very simple happens and they can no longer divide, only mate in pairs. The primitive, efficient and simple mechanism gets terminated and replaced with a different one, incredibly complex one!

Sure, we have protozoa which have similar reproductive mechanisms. They exchange genetic material to multiply.

But look at our, human cells. They dont need that! Look at some reptiles, some plants that only take one to make another. They don't pair as well! It's simple. Efficient. Why do protozoa need 2 for the species to survive?

It's not simple and efficient [tho helps us adapt, but its not my point for now]. See, things like this make ne wonder. What if we, the life, are not as accidental as we think? What if this whole mechanism was set off by someone or something billions of years ago? That's mean there are much older, much more superior cognitive organisms than us. What if protozoa was version 3 of new life [the first two did not survive]? Viruses - v2? Sea creatures - v3, reptiles - v4, and so on until they came up with us, mammals? That'd surely mean we are not alone in this universe. Are they watching us? Will they create a new species any time soon? What's our purpose, are we just an experiment?

And so, from cherry blossoms to existensial dilemma, my stroll is over. Time for breakfast :)

After examining my model and code closer, albeit as rudimentary as it is, I'm now pretty certain I didnt fuck up the encoder, which means the system is in fact learning the training sequence pairs, which means it SHOULD be able to actually factor semiprimes.

And looking at this, it means I fucked up the decoder and I have a good idea how. So the next step is to fix that.

I'm also fairly certain, using a random forest approach, namely multiple models trained on other variables derived from the semiprimes, I can extend the method, and lower loss to the point where I can factor 400 digit numbers instead of 20 digit numbers.

"Reflective" programming...

In almost every other language:
1. obj.GetType().GetProperties()
or
for k, v in pairs(obj) do something end
or
fieldnames(typeof(obj))
or
Object.entries(obj)

2. Enjoy.

In C++: 💀
1. Use the extern keyword to trick compilers into believing some fake objects of your chosen type actually exist.

2. Use the famous C++ type loophole or structured binding to extract fields from your fake objects.

3. Figure out a way to suppress those annoying compiler warnings that were generated because of your how much of a bad practice your code is.

4. Extract type and field names from strings generated by compiler magic (__PRETTY_FUNCTION__, __FUNCSIG__) or from the extremely new feature std::source_location (people hate you because their Windows XP compilers can't handle your code)

5. Realize your code still does not work for classes that have private or protected fields.

6. Decide it's time to become a language lawyer and make OOPers angry by breaking encapsulation and stealing private fields from their classes using explicit template instantiation

7. Realize your code will never work outside of MSVC, GCC or CLANG and will always be reliant on undefined behaviors.

8. Live forever in doubt and fear that new changes to the compiler magic you abused will one day break your code.

9. SUFFER IN HELL as you start getting 5000 lines worth of template errors after switching to a new compiler.

My problem with referring to my github:
I just found a project from almost two years ago where I exclusively use unordered arrays of key/value pairs as dictionaries.
Man, fuck previous me.

Went for shopping last weekend to buy some cloths for "office". Bought 3 pairs of sweatpants.

Headsup: if you're making a game, or want to, a good starting point is to ask a single question.
How do I want this game to feel?

A lot of people who make games get into it because they play and they say I wish this or that feature were different. Or they imagine new mechanics, or new story, or new aesthetics. These are all interesting approaches to explore.

If you're familiar with a lot of games, and why and how their designs work, starting with game
feel is great. It gives you a palette of ideas to riff on, without knowing exactly why it works, using your gut as you go. In fact a lot of designers who made great games used this approach, creating the basic form, and basically flew-blind, using the testing process to 'find the fun'.

But what if, instead of focusing on what emotions a game or mechanic evokes, we ask:
How does this system or mechanic alter the
*players behaviors*? What behaviors
*invoke* a given emotion?

And from there you can start to see the thread that connects emotion, and behavior.

In *Alien: Isolation*, the alien 'hunts' for the player, and is invulnerable. Besides its menacing look, and the dense atmosphere, its invincibility
has a powerful effect on the player. The player is prone to fear and running.

By looking at behavior first, w/ just this one game, and listing the emotions and behaviors
in pairs "Fear: Running", for example, you can start to work backwards to the systems and *conditions* that created that emotion.

In fact, by breaking designs down in this manner, it becomes easy to find parallels, and create
these emotions in games that are typically outside the given genre.

For example, if you wanted to make a game about vietnam (hold the overuse of 'fortunate son') how might we approach this?

One description might be: Play as a soldier or an insurgent during the harsh jungle warfare of vietnam. Set ambushes, scout through dense and snake infested underbrush. Identify enemy armaments to outfit your raids, and take the fight to them.

Mechanics might include

1. crawl through underbrush paths, with events to stab poisonous snacks, brush away spiders or centipedes, like the spiders in metro, hold your breathe as armed enemy units march by, etc.

2. learn to use enfilade and time your attacks.

3. run and gun chases. An ambush happens catching you off guard, you are immediately tossed behind cover, and an NPC says "we can stay and fight but we're out numbered, we should run." and the system plots out how the NPCs hem you in to direct you toward a series of
retreats and nearest cover (because its not supposed to be a battle, but a chase, so we want the player to run). Maybe it uses these NPC ambushes to occasionally push the player to interesting map objectives/locations, who knows.

4. The scouting system from State of Decay. you get a certain amount of time before you risk being 'spotted', and have to climb to the top of say, a building, or a tower, and prioritize which objects in the enemy camp to identity: trucks, anti-air, heavy guns, rockets, troop formations, carriers, comms stations, etc. And that determines what is available to 'call in' as support on the mission.

And all of this, b/c you're focusing on the player behaviors that you want, leads to the *emotions* or feelings you want the player to experience.

Point is, when you focus on the activities you want the player to *do* its a more reliable way of determining what the player will *feel*, the 'role' they'll take on, which is exactly what any good designer should want.

If we return back to Alien: Isolation, even though its a survival horror game, can we find parallels outside that genre? Well The Last of Us for one.

How so? Well TLOU is a survival third-person shooter, not a horror game, and it shows. Theres
not the omnipresent feeling of being overpowered. The player does use stealth, but mostly it's because it serves the player's main role: a hardened survivor whos a capable killer, struggling through a crapsack world. The similarity though comes in with the boss battles against the infected.

The enemy in these fights is almost unstoppable, they're a tank, and the devs have the player running from them just to survive. Many players cant help but feel a little panic as they run for their lives, especially with the superbly designed custom death scenes for joel. The point is, mechanics are more of a means to an end, and if games are paintings, and mechanics are the brushes, player behavior is the individual strokes and player emotion is the color. And by examining TLOU in this way, it becomes obvious that while its a third person survival shooter, the boss fights are *overtones* of Alien: Isolation.

And we can draw that comparison because like bach, who was deaf, and focused on the keys and not the sound, we're focused on player behavior and not strictly emotions.

The networking group at my day job, hooooooolly crap I have some unprintable words. But keeping it professional:

* Days to turn around simple firewall whitelisting requests
* Expecting other teams to know the network layout despite not sharing that information anywhere and going out of their way to not share it
* Adding bureaucracy in the form of separate Word doc forms despite having a ticketing system - for no justifiable reason
* Breaking production systems multiple times per month
* Calling in with problems that are clearly network related, being told it’s our systems, and then the problems magically go away even though they swear they didn’t touch anything
* Outright verifiable lies or vague non-answers when they’re not talking to someone at the director level or a vendor from an outside company on conference calls
* Worse packet loss and throughput on our LAN than my home ISP

Doing anything with these clowns is my single biggest source of stress right now. I can’t wait until we get a full SDN stack set up and then we won’t have to deal with them for day-to-day needs any longer.

My boss swears it’s better that we’re not managing the network directly, but I’m pretty sure my friend’s dog could be loosed into the data center to chew on fiber, and eventually the pairs would be connected in such a way as to improve performance.

StackOverflow locked my account. I'm hoping someone here might be kind enough to help me with a bash script I'm "bashing" my head with. Actually, it's zsh on MacOS if it makes any difference.

I have an input file. Four lines. No blank lines. Each of the four lines has two strings of text delimited by a tab. Each string on either side of the tab is either one word with no spaces or a bunch of words with spaces. Like this (using <tab> as a placeholder here on Devrant for where the tab actually is)

ABC<tab>DEF
GHI<tab>jkl mno pq
RST<tab>UV
wx<tab>Yz

I need to open and read the file, separate them into key-value pairs, and put them into an array for processing. I have this script to do that:

# Get input arguments
search_string_file="$1"
file_path="$2"

# Read search strings and corresponding names from the file and store in arrays
search_strings=()
search_names=()

# Read search strings and corresponding names from the file and store in arrays
while IFS= read -r line || [[ -n "$line" ]]; do
echo "Line: $line"
search_string=$(echo "$line" | awk -F'\t' '{print $1}')
name=$(echo "$line" | awk -F'\t' '{print $2}')
search_strings+=("$search_string")
search_names+=("$name")
done < "$search_string_file"

# Debug: Print the entire array of search strings
echo "Search strings array:"
for (( i=0; i<${#search_strings[@]}; i++ )); do
echo "[$i] ${search_strings[$i]} -- ${search_names[$i]}"
done

However, in the output, I get the following:

Line: ABC<tab>DEF
Line: GHI<tab>jkl mno pq
Line: RST<tab>UV
Line: wx<tab>Yz
Search strings array:
[0] --
[1] ABC -- DEF
[2] GHI -- jkl mno pq
[3] RST -- UV

That's it. I seem to be off by one because that last line...

Line: wx<tab>Yz

never gets added to the array. What I need it to be is:

[0] ABC -- DEF
[1] GHI -- jkl mno pq
[2] RST -- UV
[3] wx -- Yz

What am I doing wrong here?

Thanks.

Literally dealing with a dev in a technology I know the most(and he barely knows), with him trying to give me orders because he wants to. We are pairs, but he has been more time in the project so "he's the leader", but he's acting like a boss. How to deal with that bullshit?

I think he feels attacked on his role

Fucking hashtables...I forgot that removals can screw with the probing sequence, causing later lookups to "randomly" fail after hundreds of operations and elements.

Spent 4 hours staring at 3 while loops and data sets of hundreds of key value pairs trying to figure out why one giant data set worked fine but the other failed on some lookups.

How do you type with pairs of characters like () [] <> "" etc.?
Do you type them both, then move the cursor back and type the stuff inside or do you type the first of the pair, then type the stuff inside and then close it with the second of the pair?

I just realized I do both techniques, apparently randomly, which weirds me out.
Also my IDE often places the second character of the pair automatically.

Revision to the Peter/Dilbert Principle, the ProjektAquarius principle: a company will systematically shift the least competent employee on to the assignments the competent employees can't be bothered to do until they become an integral part of the team and drag you down with them. (E.g. eventually they completely fuck up your delivery process, although it's probably still cheaper and quicker than having them do anything else.)

ProjektAquarius principle: A Case Study

We have an engineer who is getting paid quite a bit more than me. Over time his responsibilities have gradually been reduced to documentation and running our almost entirely automated build. Well today the build failed. He pulls me over to tell me, and says he's confused because there is a file there he has never seen before in there and a file he always has seen that isn't there (basically a file got renamed. It was not non-obvious). Answer: change the file name.

Then he comes over and tells us that it's failing again because the script is not finding a file. So a coworker of mine and I go over. He explains the whole build process to us when we ask if there is any point in the script that would help us identify where the script is looking for the file and failing (there wasn't but that's besides the point).

Turns out, he had decided to put the assembly list in order. Normally no problem, but the list is in source destination pairs. So the fucking file was being put in a different directory than the one the script was looking for it in and failing. And that's the story about how my company just paid 3 engineers a quarter of a man hour each for something that would have been resolved in 30 seconds via file search/copying and pasting a file path. Related note: our process for building an install is now about 4 hours long with no change on process besides the BCAK.

I finally got the lstm to a training and validation loss of < 0.05 for predicting the digits of a semiprime's factors.

I used selu activation with lecun normal initialization on a dense decoder, and compiled the model with Adam as the optimizer using mean squared error.

Selu is self-normalizing, meaning it tends to mean 0 and preserves a standard deviation of one, so it eliminates the exploding/vanishing gradient problem. And I can get away with this specifically because selu *only* works on dense layers.

I chose Adam, even though this isn't a spare problem, because Adam excels on noisy problems and non-stationary objectives (definitely this), and because adam typically doesn't require a lot of hyperparameter tuning its ideal here, especially considering because I don't know what the hyperparameters should be to begin with.

I did work out some general guidelines on training quantity vs validation, etc.
The initial set wasn't huge or anything, roughly 110k pairs for training.

It converged pretty quick all things considered, and to the low loss like I mentioned, but even then the system always outputs the same result, regardless of the input, so obviously I'm doing something incorrectly.

The effectiveness of this approach for training and validation makes me question if I haven't got something wildly wrong. Still exploring though and figuring out how to get my answers back out. I'm hoping I just fucked up the output, and not the input as well.

Ugh I hate having to write c/c++ files in pairs of implementation and headers... Oh wait that's what bash scripts are made to solve! :D

/observation

I've found that a caramel latte pairs nicely with kettle-cooked bbq potato chips.

Or I'm just weird.

Rewriting all my MIT App Inventor apps that use online resources to make them use the new dictionaries instead of lists of pairs for the JSON responses. Super fun.

Optimization concepts/patterns or instances?

For pattern its gotta be any time i can take a O(n^2) and turn it into O(n) or literally anything better than O(n^2).

Instance would probably be the time that we took an api method that returned a json list made up of dictionaries CSV-style and changed it into a dictionary with the uid as the key and the other info as key-value pairs in a sub-dictionary. So instead of:

[
{
"Name": name,
"Info":info
}
]

We now return:

{
name:
{
"Info": info
}
}

Which can, if done right, make your runtime O(1), which i love.

Is there a portable DB format like sqlite but stores data like Mongo.

Each record contains key value pairs.

I guess I could install Mongo again... But kinda want to play with the data first. Pulls from a web api

I guess other alternative is to just save the json responses to disk in separate folders and files for now...

And abstract the DB layer behind an interface

😂😂😂 mfw redid all my logging statements today to change sentences into keyvalue pairs (for log querying) and the script broke due to an invalid parameter reference in one of the debug statements.

Causing more errors trying to prevent errors smh

I've been getting a lot of mixed input on this lately and I'm curious to gauge the public opinion on it.

For key identifiers in key/value pairs (eg. days of the week, high/med/low, etc), is it preferable with semantic string naming wherever possible, or are int enums usually preferred for being more clean and robust?

I suppose it's a case of "it depends". I tend to use stringed keys myself since they are more readable but I do think it's a hassle with asserting case insensitivity and how the keys can be accessed as properties - "sometimes, probably".

People often comment on it when they see it, and it turns into this weird mutual "why strings?" vs. "why ints?".

I just like bulding silly things, my ideal devjob would be one where I could just make random junk that makes me smile all day...

Like recently I made an NoSQL database using azure AD. They give you 50000 AD objects free, but I found you could encode all sorts of data in the AD objects variables. So basically I setup a framework that uses Security groups as Collections, AD objects as Documents, and object variables as key pairs.

It's really slow, like roughly 50 queries a minute, but hey. It was fun proving it could be done...

Yeah, that would be my ideal devjob :P that kind of stuff all day

the red haired girl and the blue haired girl.

there was this story about a programmer who spent years studying computer science before finally getting a job.

the dev studied only computer science and was put on blue team after a few days.

a few hours into one of the constant coding sessions, the boss told the devs that red team members and blue team members would be working in pairs.

the person from red team transferred the devs work to their data base without the dev knowing, then locked down the devs computer. the dev could not do anything. later, the dev got fired for not doing any work. after that, the company got millions of dollars, and the dev did not see any of it.

both the dev and the managers made a note not to hire any programmer who cannot secure their work.

it is not ethical to teach people programming without also teaching them cyber security.

computer networking, programming and security should all be the same major.

it is a bad idea to teach people how to build anything without telling them how to secure it.

the story above was just a scenario, but it probably happens way more often than people think.

Schools should teach both things in the same major.

I need MD5/original size (in bytes) pairs to test my engine and see if i can get back the originals in any reasonable amount of time.

Any offers?

Was generating a JSON based config manually to be used by a script another dev wrote - only to be criticized for using the text editors built in formatter. Evidently lining up the colon separating key value pairs is a thing.

If readability was so important to you why the fuck did you decide on using JSON as a configuration format? Especially when you could have gone with YAML or better yet INI (flat key/value pairs) style config.

Persisterising derived values. Often a necessary evil for optimisation or privacy while conflicting with concerns such as auditing.

Password hashing is the common example of a case considered necessary to cover security concerns.

Also often a mistake to store derived values. Some times it can be annoying. Sometimes it can be data loss. Derived values often require careful maintenance otherwise the actual comments in your database for a page is 10 but the stored value for the page record is 9. This becomes very important when dealing with money where eventual consistency might not be enough.

Annoying is when given a and b then c = a + b only b and c are stored so you often have to run things backwards.

Given any processing pipeline such as A -> B -> C with A being original and C final then you technically only need C. This applies to anything.

However, not all steps stay or deflate. Sum of values is an example of deflate. Mapping values is an example of stay. Combining all possible value pairs is inflate, IE, N * N and tends to represent the true termination point for a pipeline as to what can be persisted.

I've quite often seen people exclude original. Some amount of lossy can be alright if it's genuine noise and one way if serving some purpose.

If A is O(N) and C reduces to O(1) then it can seem to make sense to store only C until someone also wants B -> D as well. Technically speaking A is all you ever need to persist to cater to all dependencies.

I've seen every kind of mess with processing chains. People persisting the inflations while still being lossy. Giant chains linear chains where instead items should rely on a common ancestor. Things being applied to only be unapplied. Yes ABCBDBEBCF etc then truncating A happens.

Extreme care needs to be taken with data and future proofing. Excess data you can remove. Missing code can be added. Data however once its gone its gone and your bug is forever.

This doesn't seem to enter the minds of many developers who don't reconcile their execution or processing graphs with entry points, exist points, edge direction, size, persistence, etc.
