Just found out the backend developer I’m always complaining about. The one who:
- Can’t implement OAuth, and we have to have app users login every 24 hours because we have no way to generate new refresh tokens.
- Who used the phrase “your time zone is not my concern” to avoid building something that would let us inject test data.
- Who’s been debugging a critical bug affecting many users since December.
- Who can’t conduct API tests from external internet (you know, like the way the app will be in the wild) because it takes too much time.
- Who replies to Jira tickets only on a blue moon.
- Who has been 90% of the reason for my blood pressure situation
... is a fucking principal engineer in this company. In pecking order, his opinion should be considered more valuable than mine and everyone on my team.
I’ve just lost the will to live. How are big organizations THIS bad. Seriously, what promotion discussion did he go into
“So, you are a complete and utter bastard, nobody can stand to speak to you and you’ve yet to deliver anything of worth that actually works, over the course of several years ... ... ... interested in having your pay doubled??”20 -
I'm convinced code addiction is a real problem and can lead to mental illness.
Dev: "Thanks for helping me with the splunk API. Already spent two weeks and was spinning my wheels."
Me: "I sent you the example over a month ago, I guess you could have used it to save time."
Dev: "I didn't understand it. I tried getting help from NetworkAdmin-Dan, SystemAdmin-Jake, they didn't understand what you sent me either."
Me: "I thought it was pretty simple. Pass it a query, get results back. That's it"
Dev: "The results were not in a standard JSON format. I was so confused."
Me: "Yea, it's sort-of JSON. Splunk streams the result as individual JSON records. You only have to deserialize each record into your object. I sent you the code sample."
Dev: "Your code didn't work. Dan and Jake were confused too. The data I have to process uses a very different result set. I guess I could have used it if you wrote the class more generically and had unit tests."
<oh frack...he's been going behind my back and telling people smack about my code again>
Me: "My code wouldn't have worked for you, because I'm serializing the objects I need and I do have unit tests, but they are only for the internal logic."
Dev:"I don't know, it confused me. Once I figured out the JSON problem and wrote unit tests, I really started to make progress. I used a tuple for this ... functional parameters for that...added a custom event for ... Took me a few weeks, but it's all covered by unit tests."
Me: "Wow. The way you explained the project was; get data from splunk and populate data in SQLServer. With the code I sent you, sounded like a 15 minute project."
Dev: "Oooh nooo...its waaay more complicated than that. I have this very complex splunk query, which I don't understand, and then I have to perform all this parsing, update a database...which I have no idea how it works. Its really...really complicated."
Me: "The splunk query returns what..4 fields...and DBA-Joe provided the upsert stored procedure..sounds like a 15 minute project."
Dev: "Maybe for you...we're all not super geniuses that crank out code. I hope to be at your level some day."
<frack you ... condescending a-hole ...you've got the same seniority here as I do>
Me: "No seriously, the code I sent would have got you 90% done. Write your deserializer for those 4 fields, execute the stored procedure, and call it a day. I don't think the effort justifies the outcome. Isn't the data for a report they'll only run every few months?"
Dev: "Yea, but Mgr-Nick wanted unit tests and I have to follow orders. I tried to explain the situation, but you know how he is."
<fracking liar..Nick doesn't know the difference between a unit test and breathalyzer test. I know exactly what you told Nick>
Dev: "Thanks again for your help. Gotta get back to it. I put a due date of April for this project and time's running out."
APRIL?!! Good Lord he's going to drag this intern-level project for another month!
After he left, I dug around and found the splunk query, the upsert stored proc, and yep, in about 15 minutes I was done.1 -
Just the other day I got back from getting an extra monitor.. and just when I came back home, some older lady that also lives in this residence came to me, all panicked because her left car lights wouldn't turn off. So she asked me whether I could fix it, because I'm a man and therefore technical... Yeah.
Told her I don't know anything about cars (I don't even have a driver's license), and she should ask someone else.. but she kept clinging on to me and eventually I figured.. screw it, how hard can it be?
Got to her car, yada yada yada.. lady opens the door, and it's full of fucking buttons everywhere! No fucking way that I'm gonna dabble with those. So, do the easiest thing first.
"Ma'm, could you please turn on the car?"
*Turns car on, all lights light up*
🤔 Fair enough...
"Hmm.. and what happens if you turn it off now?"
*Turns car off, all lights go off*
Lady: "I've got no idea how you've done it but thank you so much, you're an angel!! 😊"
Me: "Well.. 😅 let's just say that turning it on, off and back on again works at least 90% of the time..."13 -
I am much too tired to go into details, probably because I left the office at 11:15pm, but I finally finished a feature. It doesn't even sound like a particularly large or complicated feature. It sounds like a simple, 1-2 day feature until you look at it closely.
It took me an entire fucking week. and all the while I was coaching a junior dev who had just picked up Rails and was building something very similar.
It's the model, controller, and UI for creating a parent object along with 0-n child objects, with default children suggestions, a fancy ui including the ability to dynamically add/remove children via buttons. and have the entire happy family save nicely and atomically on the backend. Plus a detailed-but-simple listing for non-technicals including some absolutely nontrivial css acrobatics.
After getting about 90% of everything built and working and beautiful, I learned that Rails does quite a bit of this for you, through `accepts_nested_params_for :collection`. But that requires very specific form input namespacing, and building that out correctly is flipping difficult. It's not like I could find good examples anywhere, either. I looked for hours. I finally found a rails tutorial vide linked from a comment on a SO answer from five years ago, and mashed its oversimplified and dated examples with the newer documentation, and worked around the issues that of course arose from that disasterous paring.
like.
I needed to store a template of the child object markup somewhere, yeah? The video had me trying to store all of the markup in a `data-fields=" "` attrib. wth? I tried storing it as a string and injecting it into javascript, but that didn't work either. parsing errors! yay! good job, you two.
So I ended up storing the markup (rendered from a rails partial) in an html comment of all things, and pulling the markup out of the comment and gsubbing its IDs on document load. This has the annoying effect of preventing me from using html comments in that partial (not that i really use them anyway, but.)
Just.
Every step of the way on building this was another mountain climb.
* singular vs plural naming and routing, and named routes. and dealing with issues arising from existing incorrect pluralization.
* reverse polymorphic relation (child -> x parent)
* The testing suite is incompatible with the new rails6. There is no fix. None. I checked. Nope. Not happening.
* Rails6 randomly and constantly crashes and/or caches random things (including arbitrary code changes) in development mode (and only development mode) when working with multiple databases.
* nested form builders
* styling a fucking checkbox
* Making that checkbox (rather, its label and container div) into a sexy animated slider
* passing data and locals to and between partials
* misleading documentation
* building the partials to be self-contained and reusable
* coercing form builders into namespacing nested html inputs the way Rails expects
* input namespacing redux, now with nested form builders too!
* Figuring out how to generate markup for an empty child when I'm no longer rendering the children myself
* Figuring out where the fuck to put the blank child template markup so it's accessible, has the right namespacing, and is not submitted with everything else
* Figuring out how the fuck to read an html comment with JS
* nested strong params
* nested strong params
* nested fucking strong params
* caching parsed children's data on parent when the whole thing is bloody atomic.
* Converting datetimes from/to milliseconds on save/load
* CSS and bootstrap collisions
* CSS and bootstrap stupidity
* Reinventing the entire multi-child / nested params / atomic creating/updating/deleting feature on my own before discovering Rails can do that for you.
Just.
I am so glad it's working.
I don't even feel relieved. I just feel exhausted.
But it's done.
finally.
and it's done well. It's all self-contained and reusable, it's easy to read, has separate styling and reusable partials, etc. It's a two line copy/paste drop-in for any other model that needs it. Two lines and it just works, and even tells you if you screwed up.
I'm incredibly proud of everything that went into this.
But mostly I'm just incredibly tired.
Time for some well-deserved sleep.7 -
literally what the fuck is the point of C++
>takes 3 years to make anything half-functional
>language was made in like fucking 1902 so it's damn near fucking impossible to make anything that works without sifting through bumfuck retarded syntax/libraries
>error messages that tell you absolutely nothing of use and are indecipherable garbage 90% of the time
fuck C, fuck it's retarded downie little brother C++, and fuck the stupid fucking boomers who say you're not a real programmer unless you force yourself to become a masochist by using either one of these stupid fucking languages
"oh but it's fast!!11!1!!" yeah but working with it sure as fuck isn't
half the fucking time if I just stop including certain headers in another file then the compiler throws like literally 400 fucking errors at me even though the thing(s) I excluded had no bearing on whatever the compiler decides it wants to loudly bitch and whine about
"oh but games were made on it!!!!111!" yeah not without fucking horrific spaghetti code and 900000 different libraries and dependancies designed just to make a single fucking window39 -
So I found this consulting job a while ago thinking that some extra cash while studying would be nice to have.
I meet with the guy, a researcher trying to start a business up, good for him I think, maybe we'll hit it off, continue working, why not? Except he has no clue how to write working code, all he ever did was writing matlab scripts he says, thats why he hired me he says.
Okay, fine, you do your job I do mine.
He hands me the contract, its about comparing two libraries, finding out which one is better suited for his job, cool, plots and graphs everywhere.
Except this is an unpaid job. YOU WHAT?! It's a test job. FINE. At least it'll look good on my resume.
We talk about the paid part where I'm supposed to scale the two libraries, looks good, as expected from an ML engineering perspective. It comes to payment. The dude has no idea how taxes work, says he has a set amount to pay and not a penny more. I explain with examples how taxes are paid, how you get reimbursed for them and so on. Won't budge. Screws me over.
Opens the door for other jobs I think, he'll learn next time I think and take the job.
Fast forward a month, 90% of the job done, he adds a third thing to compare. Gives a github link to a repo with 2 authors, last commit a year ago. There are links to a 404, claiming compiled jars. Fuck.
Not my first rodeo, git clone that shit, make compile, the works. The thing uses libs that ain't in no repo, that would be too easy. Run, error, find lib, remake all the things, rinse repeat.
The scripts they got have hardcoded paths and filenames for 2 year old binaries, remake that shit.
It works, at least I get a prompt now. Try the example files they got, no luck, some missing unlinked binary somewhere, but not a name mentioned. Cross reference the shit outta the libs mentioned on readme, find the missing shit, down it.
Available versions are too new, THE MOLDING NUTCRACKER uses some bug in an old version of the lib.
I give up. Fuck this. This ain't worth the money OR time. Wanker... -
Okay, I'm interning at a government institution & boy let me just tell you... mmmh... A FUCKING MESS!
So I'm tasked with developing a HR system that the whole company should eventually use. I tell them I'm not familiar with the open source technologies they'd like me to use, they tell me no worries, you can develop a prototype with a tech stack that you're familiar with. Also, they tell me that they don't quite have the requirements from HR so what I can do for my prototype is just develop something "general" that works according to their "idea".
Being the good intern I am, I develop quite a good functioning prototype & present it to the team who then present it to the managers.
Finally we're all called in for a final meeting with the managers & HR, and guess what? The requirements for the system are different. Almost 90% of the features we built into the prototype need to change. Also, the system must use open source technologies. The managers promise to send a detailed requirements specification document, with sample data. I think this is a great idea as there's still a lot I don't understand. I expected this to happen, so I soon start to redesign afresh, this time trying as hard as possible to consider open source technologies within my plans.
But noooo... My team wants me to "finish" the system!
"Finish" what system, I ask? That was a prototype!
"Just tweak the functionality you built to meet the new requirements".
WTF!
We don't even have the actual requirements specification document, so I'll still be coding blindly. Also, the whole system needs to be re-built using open source technology!
Instead of pushing me to develop a system blindly, with no requirements, how about you push HR to tell you exactly what they need and how it should work first!?
I'm honestly exhausted with the false sense of urgency from my team!!8 -
I didn't leave, I just got busy working 60 hour weeks in between studying.
I found a new method called matrix decomposition (not the known method of the same name).
Premise is that you break a semiprime down into its component numbers and magnitudes, lets say 697 for example. It becomes 600, 90, and 7.
Then you break each of those down into their prime factorizations (with exponents).
So you get something like
>>> decon(697)
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')]]
And it turns out that in larger numbers there are distinct patterns that act as maps at each offset (or magnitude) of the product, mapping to the respective magnitudes and digits of the factors.
For example I can pretty reliably predict from a product, where the '8's are in its factors.
Apparently theres a whole host of rules like this.
So what I've done is gone an started writing an interpreter with some pseudo-assembly I defined. This has been ongoing for maybe a month, and I've had very little time to work on it in between at my job (which I'm about to be late for here if I don't start getting ready, lol).
Anyway, long and the short of it, the plan is to generate a large data set of primes and their products, and then write a rules engine to generate sets of my custom assembly language, and then fitness test and validate them, winnowing what doesn't work.
The end product should be a function that lets me map from the digits of a product to all the digits of its factors.
It technically already works, like I've printed out a ton of products and eyeballed patterns to derive custom rules, its just not the complete set yet. And instead of spending months or years doing that I'm just gonna finish the system to automatically derive them for me. The rules I found so far have tested out successfully every time, and whether or not the engine finds those will be the test case for if the broader system is viable, but everything looks legit.
I wouldn't have persued this except when I realized the production of semiprimes *must* be non-eularian (long story), it occured to me that there must be rich internal representations mapping products to factors, that we were simply missing.
I'll go into more details in a later post, maybe not today, because I'm working till close tonight (won't be back till 3 am), but after 4 1/2 years the work is bearing fruit.
Also, its good to see you all again. I fucking missed you guys.9 -
Still on the primenumbers bender.
Had this idea that if there were subtle correlations between a sufficiently large set of identities and the digits of a prime number, the best way to find it would be to automate the search.
And thats just what I did.
I started with trace matrices.
I actually didn't expect much of it. I was hoping I'd at least get lucky with a few chance coincidences.
My first tests failed miserably. Eight percent here, 10% there. "I might as well just pick a number out of a hat!" I thought.
I scaled it way back and asked if it was possible to predict *just* the first digit of either of the prime factors.
That also failed. Prediction rates were low still. Like 0.08-0.15.
So I automated *that*.
After a couple days of on-and-off again semi-automated searching I stumbled on it.
[1144, 827, 326, 1184, -1, -1, -1, -1]
That little sequence is a series of identities representing different values derived from a randomly generated product.
Each slots into a trace matrice. The results of which predict the first digit of one of our factors, with a 83.2% accuracy even after 10k runs, and rising higher with the number of trials.
It's not much, but I was kind of proud of it.
I'm pushing for finding 90%+ now.
Some improvements include using a different sort of operation to generate results. Or logging all results and finding the digit within each result thats *most* likely to predict our targets, across all results. (right now I just take the digit in the ones column, which works but is an arbitrary decision on my part).
Theres also the fact that it's trivial to correctly guess the digit 25% of the time, simply by guessing 1, 3, 7, or 9, because all primes, except for 2, end in one of these four.
I have also yet to find a trace with a specific bias for predicting either the smaller of two unique factors *or* the larger. But I haven't really looked for one either.
I still need to write a generate that takes specific traces, and lets me mutate some of the values, to push them towards certain 'fitness' levels.
This would be useful not just for very high predictions, but to find traces with very *low* predictions.
Why? Because it would actually allow for the *elimination* of possible digits, much like sudoku, from a given place value in a predicted factor.
I don't know if any of this will even end up working past the first digit. But splitting the odds, between the two unique factors of a prime product, and getting 40+% chance of guessing correctly, isn't too bad I think for a total amateur.
Far cry from a couple years ago claiming I broke prime factorization. People still haven't forgiven me for that, lol.6 -
The primary concept of reactive programming is great. The idea that things just naturally re-run when anything they rely on is changed is amazing. Really, I think it's the next step in programming language development and within a decade or two at least one of the top 5 programming languages will be built entirely on this principle.
BUT
Expecting every dependency to be used unconditionally is stupid. Code that checks everything it might need all the time even if a decision can be made from much less information is simply bad, inefficient code. If you want to build a list of dependencies automatically, you have to parse the source.
And I really hate that there are TONS of languages that either make the AST readable at runtime or ship with a very powerful preprocessor that could be used to analyse expressions and build dependency lists, but by its sheer popularity the language we're trying to knead into something it was never and still isn't meant to be is JavaScript.3 -
A little example of how recriutment in IT works.
Mechanic gets a live mechanic skill test to get a job, as he really wants this job because of lack of money he asks recriuter couple of questions.
Mechanic: do I need to bring my own tools ?
HR: no everything will be provided in place
Mechanic: what would I do during this test ?
HR: everything will be explained just before the test I’m not an engineer so engineer will explain everything to you
The test day, mechainc goes to the test place and the recriuter says:
Recruiter: Your first task is really simple, please tighten those screws, you have 10 minutes
Mechanic: But I don't see the screw driver
Recriuter: I can't say to you how to do it, you figure something out
Mechanic somehow manages to tighten those screws using his belt
Recriuter: Ok so now tell me what force is needed to unscrew them and tell me if you did good if I’d say you need to tighten 1 million screws
Mechanic: I just want to do my job
Recruiter: Hey we are looking for people with broad experience for this position, of course you wont be asked to do that task but we want to know if you’re capable to do the job if we ask you.
Mechanic: answers the question that he will use tools and what devices he will use to measure the force
Recriuter: Can you write this as a mathematical equation ?
Mechanic: don’t know that
Recruiter: Well we can’t hire you we are looking for someone with more knowledge about the topic
Mechanic: But you keep asking me about the fucking screws
Recruiter: Watch your mouth sir because for me you are junior mechanics, you don’t know how to use proper tools and you barely manage to do the first task in time I would use: started elaborating about tools to tighten many screws at a time in a distributed fashion
Mechanic: but to run those tools I would need more than 10 minutes and besides that those are not here
Recruiter: yes they are, we open those doors to get them before our work you suppose to know that and we use those all the time, it was in job description, besides that it is recommended by company xyz to keep those tools behind blue doors, there is nothing here besides blue doors and room with tools and you didn’t know what blue doors are for, you need to learn the basics first
Mechanic resigns. 90% luck 10% skill
Every fucking time.7 -
All I am asking for is a debugger in Xcode that works as well as Macintosh Programmer's Workshop ( MPW) circa 80's/90's. Maybe I am being unreasonable?
I stepped a line in the debugger and all the variables disappear... and all I get is the spinny "fuck you" indicator and the variables all disappear.
But here is the worst part... Apple isn't holding any of those fucktards on the Xcode team accountable for producing a shit product.
I'm really glad I don't have to do this as a full time job anymore. Then why do I continue to pound nails with my forehead (use Xcode)?
Whip me, beat me, make me use Xcode...5 -
I'm so fucking fed up with the npm ecosystem. Every single god damn time I've had to do anything it always takes DAYS to figure out how to get anything working and I always have to try multiple tools or libraries to final get it half way sorta.
I'm so fucking annoyed right now. They always turn out not that great, have lacking features or trivial oversights in functionality and ALWAYS have garbage documentation.
I just want to build a fucking npm library with TypeScript to be used with node. That's probably the NUMBER 1 use case so how fucking hard can that be?
So obviously I start out with tsc. That's quite simple, compiles all my stuff and shits out .js and .d.ts files. Okay so how do I use them via es6 import? I don't fucking know, because it doesn't work no matter what I do. The 'module' option in tsconfig is absolutely useless btw. It does *literally* fuck all. Nada. Absolutely nothing.
Okay I'm far from defeated, maybe I'll just have to bundle it. So I waste two days finding something that half works (I'm using fusebox right now) and at last I get a stupid es6 module as a single bundle... But what about type the declarations? They are nowhere to be seen and of course there's no option for that. Because Fusebox the pile of shit that's oh so well Typescript integrated apparently doesn't think TYPE DECLARATION FILES are needed. What the actual fuck.
And that's where I'm now. I need the fucking .d.ts files so I can use it as a module with import. Do I really need another fucking piece of shit tool that bundles these files? Honestly fuck all of this. "Oh the Javascript ecosystem is so great" YEAH fucking great, alright. Where 90% of the ESTABLISHED tools and libraries (we don't talk about the landfill of all the other shit) flat out don't do what you need. Again, how fucking hard can it be to make a npm lib with typescript? That should be NATIVELY SUPPORTED. If not by npm atleast by typescripts tsc.
FUCK NPM. FUCK JAVASCRIPT. AND FUCK THE WHOLE ECOSYSTEM4 -
Damn. I am so blessed to have friends that i have. 90% of them don't even care if you live or die (60% of them would be the first to throw me in fire if that's benefitting to them) remaining 10% would be someone that slightly care, but will move on pretty quickly.
But the best thing about 1 of them is that he is bluntly honest , and willing to share his opinion.
Today we were just talking about stuff when i see this placement offer in my mail.
I have been recently feeling bad about my grades, my choice of persuing android , my choice of leaving out many other techs (like web dev or data sciences , whose jobs are coming in so much number in our college) and data structures, and my fear of not getting a good career start.
This guy is also like me in some aspects. He is also not doing any extreme level competitive programming. He doesn't even know android , web dev, ai/ml or other buzz words. He is just good in college subjects. But the fascinating thing about him,is that he is so calm about all of this! I am losing my nuts everyday my month of graduation , aug2020 is coming . And he is so peaceful about this??
So i tried discussing this issue with him .Let me share a few of his points. Note that we both are lower middle class family children in an awful, no opportunity college.
He : "You know i feel myself to be better than most of our classmates. When i see around , i don't see even 10 of them taking studies seriously. Everyone is here because of the opportunity. I... Love computer science. I never keep myself free at home. I like to learn about how stuff works, these networking, the router, i really like to learn."
"That's why i dont fear. Whatever the worst happens , i have a believe that i will get some job. Maybe later, maybe later than all of you , but i will. Its not a problem."
me: "but you are not doing anything bro! I am not doing anything ! So what if our college mates suck , Everyone out there is pulling their hairs out learning data structures, Blockchain, ai ml , hell of shit. But we are not! Why aren't you scared bro? Remember the goldman sach test you gave ? You were never able to solve beyond one question. How did you feel man? And didn't you thought maybe if i gave a year to that , i will be good enough? Don't you too want a good package bro? Everyone's getting placed at good numbers."
Him : "Again, its your thoughts that i am not doing things. I am happy learning at my own pace. Its my belief that i should be learning about networking and how hardware works first , then only its okay to learn about programming and ai ml stuff. I am not going to feel scared and start learning multiple things that i don't even wanna learn now."
"My point is whatever i am doing now, if its related to computers , then someday its gonna help me.
And i am learning ds too , very less at a time. Ds algo are things for people with extreme knowledge. We could have cleared goldman sachs if we had started learning all this stuff from 1st year, spend 2-3 years in it and then maybe we could have solved 2 -3 questions. I regret that a little, but no one told us that we should be doing this."
"And if i tell you my honest thoughts now, you ar better off without it. You are the only guy among us with good knowledge of android , you have been doing that for last 2 years. Maybe you will get better opportunity with android then with ds/algo."
"You know when i felt happy? When we gave our first placement test at sopra. I was thinking of going there all dumb. But at 11 am in night i casually told my brother about this ,and he said that its a good company. So i started studying a little and next day i sat for placement. And i could not believe myself when they told me that am selected. I was shit scared that night, when my dad came and said " you don't even want that job. Be happy that you passed it on your own". And then i slept peacefully that night and gave the most awesome interview the next day."
"Thus now i am confident that wherever my level of skills are, it is enough to get into a job . Maybe not the goldman sachs ,but i will do well enough with a smaller job too."
"Bro you don't even know... All my school mates are getting packages of 8LPA, 15LPA, 35LPA. You see they are getting that because they already won a race. They are all in better colleges and companies which come there, they will take them no matter what (because those companies want to associate themselves with their college tags). But if worst comes to worst, i won't be worried even if i have to go take 4lpa as job offer in sopra"
Damn you Aman Gupta. Love you from all my heart. Thanks for calming me down and making me realise that its okay to be average3 -
What should I do if a coworker is always trying to pawn off their work on me? Whenever a bug is found, she'll always try to throw it in my court (via passive-aggressive-reply-all emails) even though its 90% of the time, some shit she wrote. I'd rather not go to my boss, because it feels like whining. But confronting her has been difficult because she works remote, is more senior than me, and there is a slight language barrier. Honestly, I think she pretends to know less English than she does, to ignore my emails...6

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.7 -
Amount of text you need to read to do something the framework way.
At the end it turns out you can’t do it cause nobody thought about it and it’s just another piece of crap for doing simple things. You start digging inside framework code and see that something is wrong. You see copyright Google and you wonder if they have phd for selling their ass on street. Why the fuck you override the validation flag to true every time ?
Then you start invoking couple of methods and one of them works and stops that madness but you don’t know why but you proceed further so you can glue shits together to stop the ship sinking.
At the end after you’ve tried all the “simple” examples that works cause they’re stupid and you need something special you start to think if this framework is so unique and special cause it covers 90% of things, left you with hands full of crap ?
At the end after wasting whole day to change the border color of the input using couple of separate controls the framework way and when you succeeded you ask yourself really ?
One fucking event emit and couple of listeners with style change ? Damn you frameworks with your bidirectional easy fast doing shit.
Another day in paradise.6 -
Microsoft is always at it.
Hello, I recently discovered this eye candy of a looking website and how good the CSS looks (Kudos to whoever made this) , and I decided to post a rant of my own. And its about MS Edge and other applications.
So I built my own ATX tower a while back (Loving it) , and I found that it was WONDERFUL to have a computer that was brand new, that didnt have candy crush preinstalled on it when I got it.
Windows 10 users, do this:
Press WIN+I to open the settings menu.
Go to "Apps"
Scroll down the list....
How many applications do you see there that are actually useful , or that you have downloaded?
I never downloaded a Realtek Driver... and I never need it for anything to work. This is the case for 90% of the things you may see in the applications.
Why is HULU installed?
Why is NETFLIX installed?
Why is MINECRAFT BETA INSTALLED? THE BETA HASNT BEEN OUT IN YEARS?
But I digress, this is the case when I work on a computer such as my grandmothers who, bless her soul, isnt very adept at basic file management. Heck , she uses free Norton Antivirus against my recommendation to use the PAID active firewall application on her computer (VIPRE)
So needless to say she needs help. All the time.
So here comes microsoft recently, reinstalling like 15 different programs on her computer , including MS edge. Who else is tired of bloating? I know I am.
I recently found this program on Git!
Its the Sycnex Windows 10 DeBloater
But guess what? DONT USE IT.
Wanna know why?
Because if you do, it works, and if it works, it disables:
- Cortana (basic search engine for your OS, good luck finding candy crush).
- Microsoft Store (That means no XBOX games pass either)
- It breaks part of the file explorer
Wanna know why? BeCaUsE it geTs riD oF Ms EdGe
And believe it or not, apparently MS edges source code is Mandatory for certain functions on your computer. So even If you try to uninstall the browser, it stays behind in some form.
So there you have it. They hard coded it into windows.
Enjoy!
So its not even the author of the GITHUB programs fault, its just a real techincal limitation of the platform.
I hate that stuff man. I really do. There should be 20 things installed on my computer and thats it. Everything else is just, space for games on a solid state. Or Eclipse Photon, etc.
I would post links to show you guys a few things but. Unfortunately I cant post URLs yet!
However, thats my first rant. Hope you liked it.20 -
I had a pretty good year! I've gone from being a totally unknown passionate web dev to a respected full stack dev. This will be a bit lengthy rant...
Best:
- Got my first full time employment dev role at a company after being self-taught for 8+ years at the start of the year. Finally got someone to take the risk of hiring someone who's "untested" and only done small and odd jobs professionally. This kickstarted my career, super grateful for that!
- Started my own programming consulting company.
- Gained enough confidence to apply to other jobs, snatched a few consulting jobs, nailed the interviews even though I never practiced any leet code.
- Currently work as a 99% remote dev (only meet up in person during the initialization of some projects.) I never thought working remotely could actually work this well. I am able to stay productive and actually focus on the work instead of living up to the 9-5 standard. If I want to go for a walk to think I can do that, I can be as social and asocial as I want. I like to sleep in and work during the night with a cup of tea in the dark and it's not an issue! I really like the freedom and I feel like I've never been more productive.
- Ended up with very happy customers and now got a steady amount of jobs rolling in and contracts are being extended.
- I learned a lot, specialized in graph databases, no more db modelling hell. Loving it!
- Got a job where I can use my favorite tools and actually create something from scratch which includes a lot of different fields. I am really happy I can use all my skills and learn new things along the way, like data analysis, databricks, hadoop, data ingesting, centralised auth like promerium and centralised logging.
- I also learned how important softskills are, I've learned to understand my clients needs and how to both communicate both as a developer and an entrepeneur.
Worst:
- First job had a manager which just gave me the specifications solo project and didn't check in or meet me for 8 weeks with vague specifications. Turns out the manager was super biased on how to write code and wanted to micromanage every aspect while still being totally absent. They got mad that I had used AJAX for requests as that was a "waste of time".
- I learned the harsh reality of working as a contractor in the US from a foreign country. Worked on an "indefinite" contract, suddenly got a 2 day notification to sum up my work (not related to my performance) after being there for 7+ months.
- I really don't like the current industry standard when it comes to developing websites (I mostly work in node.js), I like working with static websites (with static website generators like what the Svelte.js driver) and use a REST API for dynamic content. When working on the backend there's a library for everything and I've wasted so many hours this year to fix bugs and create workarounds related to dependencies. You need to dive into a rabbit hole for every tool and do something which may work or break something later. I've had so many issues with CICD and deployment to the cloud. There's a library for everything but there's so many that it's impossible to learn about the edge cases of everything. Doesn't help that everything is abstracted away, which works 90% of the time but I use 15 times the time to debug things when a bug appears. I work against a black box which may or may not have an up to date documentation and it's so complex that it will require you to yell incantations from the F#$K
era and sacrifice a goat for it to work properly.
- Learned that a lot of companies call their complex services "microservices". Ah yes, the microservice with 20 endpoints which all do completely unrelated tasks? -
Making a hard switch to ubuntu on my desktop at home. Getting just a teeny tiny, tad, bit: absolutely fucking livid....
Trying to learn ansible, vagrant, and docker more in depth for both work and my personal projects. All that I’ve been doing is just spinning my wheels trying to figure out the stupid fuck-mothering quirks with running this shit on Windows. Yes you absolutely can use all of these tools on a Windows box. There’s plenty of ports, patches, and workarounds. But I have spent all day trying to build a few vagrant boxes and use ansible to set them up. Simple LAMP stack boxes on CentOS7. Nothing major... unfortunately I spent like 90-110 minutes trying to figure out why virtualbox wouldn’t run properly. Dumbass me forgot that I installed Hyper-V ages ago.
O...K.... whelp... hyperv provider it is...
Luckily it only took about 15 minutes to determine that Hyperv’s networking can’t be setup from vagrant because vagrant doesn’t know how to interact with the hyperv - vswitch. So networking config is ignored and all VMs run on default switch (NAT) which is annoying but workable.
Ran into other issues trying to stay SSH’ed into the VM. PowerShell core (6) ssh’es into the box perfectly fine, but every time I opened vi to edit configs my terminal color scheme and fonts got fucked harder than a 2 dollar hooker on nickel night.
I’m a bright-green text on black background kinda guy. However the terminal kept changing to bright-red text on white background! It was like getting skull-fucked by a minotaur.
After a while I said fuck it, let’s try putty. Vagrant was using it’s own ssh keypair for the boxes, at work on my mac. Works like a dream. Putty failed me hard and shit the bed, kept getting all kinds of keypair errors. At this point I was finished spent too long trying to make shit work correctly on this jankbox. With enough time and patience I probably could’ve figured all of these problems out. I’m certain that at least 70% of them were caused by user error. I’m known by many as the walking ID-10t.
But alas, I have no time left in the day to fuck around with shit that doesn’t work immediately for morons like myself. My only hang up for the longest time with a complete switch to Linux was gaming. But with Proton and WINE I’m comfortable with giving it the ol’ college try. (Shhhh, don’t remind me I dropped out of college...
...Thrice.)
The gamble here is that I’ll give more than 2 halves of a fuck about trying to get my games working. A Study environment and materials for certs and general training won’t be getting anywhere near my full attention.
So, at long last, I hope this attempt at a full *nix switch finally sticks!!!

TL;DR As time goes by, I'm feel deeply in love with linux. An infatuation? :D
Before, I really dont mind how the file system works, permission setup, library installation, etc. as long I finished my project (before like 90% of the time I copy paste cmds). But now, after many hair pulling while debugging times, crying while rolling on the floor moments, and painful production deployments (wtf! it's working on my machine/dev server rants), it helps me clearly realized how amazing it is. I might be relatively new with the OS compare to others so maybe what I feel like now is like having a crush on someone in a bus :). But still, I just wanted to say thank you to all who are giving their time in developing/improving linux distros - you are heroes!
I'm hoping that I can contribute something soon :)

My programming class kinda sucked. Here's why.
1. They taught C++. To students who had never seen a line of code in their lives. The language with 90+ keywords.
2. The teacher. We had to use switch statements to do something. It took around 300 loc. I used an array and shortened it to 5. He took some points away for not doing it correct. IT LITERALLY WORKS THE SAME AND IS SHORTER. This was not the first time I had shortened something/made it more readable and been docked points on the assignment.
3. Commenting. He told us to comment as much as possible, which is not correct. Comment what needs commenting. Not everything.
4. The compiler. We worked on windows with an online compiler. He decided teaching us to set up a compiler was too hard. We used onlinegdb, which isn't inherently bad. However, onlinegdb is based on Linux. He compiled our programs with a windows compiler.
Maybe these are just problems because I've programmed before that, but I still think they are red flags. What do you think?3 -
Fucking hate to explain basic shit to computer illiterate. Usually I don't mind, but right know I working on the project, want to automate one thing I need to do every morning, put two numbers to web page(I will explain details maybe in next rant). So I am only one who fix, buys computers, printer(for some problems I call for other repair man.). Generally speaking working as IT guy. Firm has like 50 computers, some of them has SCADA software. Some computers have Win 7, some win 8 and others win 10, can't upgrade those computers, not enough money(I can deal with this problem). And yes, computer buying is not the fastest, easiest thing too. Because is public firm, I need to do public buying(I don't know how to translate to english), and most of the time wins the lowest price, I am ok with that. But I can't on item specification write I want that model pc or it components. Example: I can't write I want intel processor, however I can write number of cores, frequency. But it's not that bad, usually i have template for all things I buy. One of the worst thing is this, our firm bought new bookkeeping software version, old version was using visual foxpro framework. Good thing I didn't initiate the purchase, because right know I would be jobless, not because I would be fired, but because our senior accountant would drive me crazy. In fact accountants drive me crazy, but I can handle it for now. As I wrote before our form has about 120 workers, major part of workers are old, like my parents age. (I am 28 btw. Mom is 55.). As you all know what happens if you say you work with computers. So our accountants are like 60 years old, got new program, don't know how to work with it, and they ask me how to do certain things. if I don't know how to I ask program's support, every question is like 90 Eur. So in short accountants expect I should know their work and how program works. If I try say something they don't like, they try to make my day hard. Next thing is our billing program. Man that worked before me done some payments import. And when I came everyone expect me to do that. Ok I did that because that people working with billing program would probably fuck it up. And I semi automated that, so I don't mind that much. Sometimes that program fucks up, like it happened yesterday, it send email invoices attachment without filename. Example: people got this attachment ".pdf"(no filename, only extension), And if you save it you need do OPEN WITH command and then select pdf reader or rename file (I don't know what easier). And surprise surprise our firm, customer support redirects all phone calls, emails to me. But I did explain to customer support what to say to people. Still they redirect it to me.
PS: This is my first job after school. I work as part time.
TL;DR Thinking my life, carrier choices. accountants are not the nicest people.8 -
Google Search Console insists there is "content wider than screen" on a one-pager I did which works very well on all tested sizes and devices, and scores 90+ on Google PageSpeed Insights.
"Validation failed - see details."
Clicked on "see details", and only saw the 1 URL I already knew, which seems to be working fine for everyone. If Google detetcs an actual issue, it would be really helpful to provide some details, otherwise this kind of false-positive crap only serves to care less about their tools (which is a bit of a shame, as they do provide a lot of value most of the time).2 -
I am legit getting tired of trying to help people improve and hit huge roadblocks because nobody seem to care if what we do works for the intended purpose.
I have seen some terrible unstable code that fails 50% of the time on run time and never was reviewed or tested on core software, but since it was worth a lot of story points, people get congratulated for finishing it but nobody bothers checking if it really works in the first place. Story points are meaningless in this Agilefall Frankenstein shit process we use and bosses keep saying they will improve it but nothing gets done.
Worst thing is my work often depends on this shit.
I swear one of my good colleague and I are trying to introduce commit and PR gating, code review, code quality to avoid as much problems as possible while speeding up CI and documentation but 90% of devs do not give a single fuck about it. They just bypass it with admin rights because it supposedly slows them down.
When I bring up to management that the processes are terrible, I get the classic "we can't force people to use these processes because we have to respect their work ethics and it is different from yours." While I get that some things are subjective, in this case that's a lot of words to say they suck and give no fucks.
Sorry for the rant, it is starting affect my morale and efficiency at work, but I know every workplace got its problems.2 -
How difficult is it to decide for your own future?
It's a month that I'm in total panic 'cause of a difficult choice I have to make about my job.
I really need some external opinions and points of view from other developers, maybe more experienced than me (I'm a medium-junior JS developer).
The situation is as follows:
1) I work as a Frontend Web Developer for a wonderful enterprise-like company with 100+ employees, where the individual rights are fully respected, there are no whatsoever pressures and there is a peaceful paradise-like atmosphere most of the days. I also love my teammates, which is something rare because I often dislike other humans.
2) I received a proposal from a Fintech startup, which required me a long time to complete a complex programming test they gave me. They look all very young, modern, fast and passioned about their job. But they are only living with bank's investments and are not producing any money at the moment. Also, I don't know if Fintech will be a successful field in the future.
3) I received another proposal, from a Healthtec startup this time, which has a lovely mission in the medical field, has received millions of investments, it's gaining some KK net each month but has a team of only 2 developers (3 with me if I accept). I know one of the developers and I remember he had issues of not getting paid months ago.
What's the problem with the first company? I totally dislike the product we are building, the development stack (fully Microsoft-based), the company's view (they still sell and think about software like in the 90's) and how the repository is managed. Everyday there are huge problems that end up blocking the frontend work and the final product is super ugly and works only if you know all the quirks behind it.
It's an old-fashioned desktop app with inside Chromium which should execute some components like graphs, tables, forms and shit like this. Every component is configurable through a property editor which is an utter giant mess of collapsed menus. I also suspect that the company's main business model is based on the difficulty to use this software (because they sell licenses and courses to use it).
There are no modern UX/UI concepts applied at all, nor they seem to care about it.
Each time I propose something there is a huge chain of approval-waiting that end up in a stale mate.
Also, it's useless to show my frustration about all these issues because I count very little in a so populated office.
------------------------------------------------
TLDR: I need to choice if staying in a Enterprise Microsoft-based and old-fashioned company, but in which the atmosphere is paradisiac or accept the risk to work for a Fintech or a Healthtec startup.
------------------------------------------------
What would you do if you were in my situation? What's for you the most stable field in the future?
Many thanks for the attention!6
