Search - ""minor" code changes"
-
My first rant here, don't know how to start, but fuck these self proclaimed senior developers who can't even get their concepts right about basic things and don't believe in reading docs.
Fuck you for asking if sequelize has a method to return details of the logged in user of your app, it's a fucking ORM you dumbfuck. You are a "full stack" developer for fuck's sake.
Fuck you for making those "minor changes" which breaks build and then blame it on any random plugin or lib used, or my commits.
Fuck you for expecting me to review your code on Sundays because you couldn't finish it on time.
I don't like java, at all, but even I get that without it we wouldn't be where we are right now and can't reach where we aspire to reach. But you can't keep chanting "Java is dead, Java is dead" every chance you get. No, it's NOT dead. Nor is going to, anytime soon.
And for god's sake, please stop choosing one library/plugin over another just on the basis of stars on repo, it's not the only (or valid) criteria. Look if you actually even need it. Think.
And please learn how to google first, and also stop using "the" before every the noun, the adjective and the verb. It's the fucking the annoying to read.
And yes, there are different linting presets out there, and just because a piece of code in a plugin/library/boilerplate is not following your specific, and may I say horrible standard, doesn't mean it's a "bad code". It's written by people who have created/worked-on these libraries as side projects on which your entire career is based upon.
And I haven't even talked about the code you write or your domain knowledge or the way you treat other people. So get off your high horse and behave like a developer, a real one.8 -
At one of my former jobs, I had a four-day-week. I remember once being called on my free Friday by an agitated colleague of mine arguing that I crashed the entire application on the staging environment and I shall fix it that very day.
I refused. It was my free day after all and I had made plans. Yet I told him: OK, I take a look at it in Sunday and see what all the fuzz is all about. Because I honestly could fathom what big issue I could have caused.
On that Sunday, I realized that the feature I implemented worked as expected. And it took me two minutes to realize the problem: It was a minor thing, as it so often is: If the user was not logged in, instead of a user object, null got passed somewhere and boom -- 500 error screen. Some older feature broke due to some of my changes and I never noticed it as while I was developing I was always in a logged in state and I never bothered to test that feature as I assumed it working. Only my boss was not logged in when testing on the stage environment, and so he ran into it.
So what really pushed my buttons was:
It was not a bug. It was a regression.
Why is that distinction important?
My boss tried to guilt me into admitting that I did not deliver quality software. Yet he was the one explicitly forbidding me to write tests for that software. Well, this is what you get then! You pay in the long run by strange bugs, hotfixes, and annoyed developers. I salute you! :/
Yet I did not fix the bug right away. I could have. It would have just taken me just another two minutes again. Yet for once, instead of doing it quickly, I did it right: I, albeit unfamiliar with writing tests, searched for a way to write a test for that case. It came not easy for me as I was not accustomed to writing tests, and the solution I came up with a functional test not that ideal, as it required certain content to be in the database. But in the end, it worked good enough: I had a failing test. And then I made it pass again. That made the whole ordeal worthwhile to me. (Also the realization that that very Sunday, alone in that office, was one of the most productive since a long while really made me reflect my job choice.)
At the following Monday I just entered the office for the stand-up to declare that I fixed the regression and that I won't take responsibility for that crash on the staging environment. If you don't let me write test, don't expect me to test the entire application again and again. I don't want to ensure that the existing software doesn't break. That's what tests are for. Don't try to blame me for not having tests on critical infrastructure. And that's all I did on Monday. I have a policy to not do long hours, and when I do due to an "emergency", I will get my free time back another day. And so I went home that Monday right after the stand-up.
Do I even need to spell it out that I made a requirement for my next job to have a culture that requires testing? I did, and never looked back and I grew a lot as a developer.
I have familiarized myself with both the wonderful world of unit and acceptance testing. And deploying suddenly becomes cheap and easy. Sure, there sometimes are problems. But almost always they are related to infrastructure and not the underlying code base. (And yeah, sometimes you have randomly failing tests, but that's for another rant.)9 -
(Interview for sde-3 position)
(continuation of https://devrant.com/rants/2132431/... )
Interviewer - *opens laptop. Gives a question.* solve this.
Me - *a bit surprised that such questions were being asked on a sde-3 level*
this is the 4th or 5th question from geeksforgeeks, isn't it? I know the answer to this. Do u still want me to solve it?
Interviewer - *not believing me* Yes
Me - okay. Well this *writing down the original solution mentioned on the site* is the verbatim code mentioned on the website, with complexity O(n^2).
However I feel this is not the optimal solution. Let me write a better solution.
*I provide a better solution*
This has a complexity of O(n log n) . What do you think?
Interviewer - Nope. This could be a lot better.
Me - okay. Let me see. Did some minor changes, added some caching (obviously this will have no effect on the base algorithm) etc
How about now?
Interviewer - nope. Still not good.
Me - okay. Can you tell me how to improve it?
Interviewer - no we are not allowed to solve problems for you. It is not our interview, it is yours.
Me - that makes no sense. Interviews are a two way street. I'd very much like to know the optimal answer to this.
Interviewer - okay
*copies down the answer from geeksforgeeks*
This is good
Me - *at first I thought this was a prank or something. *
I just mentioned this answer here.
Then I spent the next 10 minutes providing a BETTER solution.
May I know how yours is better?
Interviewer - this solution has 2-3 loops. Yours has a function calling itself.
Me - that's called divide and conquer using recursion mf!
Anyways let's take an example and do a dry run.
Interviewer - okay
*we do dry run*
Interviewer - oh yes. Yours ran faster. But it will run fast only sometimes.
Me - yes. Each time the algorithm rolls a dice to decide if it should run fast or slow. You have one goddamn awesome weed dealer man.
I got to go. Thank you for meeting me.14 -
When I was in school I had some guys walk up to me and asked:
G: Are you Feeno?
Me: Yes, what's up?
G: We need our FY project on school management system done.
Me: Okay?
G: How much will that cost us?
Me: *confused because I was still a freshman. At that point the only programming language I knew was elementary qbasic. I couldn't even write a hello world program without the help of Google*
So played along because yes we're talking about money here.
Me: It will cost you guys N amount of money (*improvised deep voice*).
G: Okay. Fair price.
* Right there they transferred half the requested amount to me. *
Holy moly! This guys aren't joking around. I don't know shit! They clearly mistook me for a senior student whose first name is Feeno, to me that was a nick referred to me by my friends.
I'm in this one for sure and it's a do or die transaction cus I'm returning no fucking money. I told my friends what had happened and they insisted I return back the money to the students and admit I can't deliver the project they were requesting.
Fuck all of yah! I'm keeping this money. Same afternoon I visited the school library with the intension of writing the code using the help of YouTube tutorials. I didn't find anything useful for qbasic as I thought I could write a full fledged school management system using qbasic.
I was lucky enough to find an existing source code on Codeproject, God bless that Indian guy. The source was in PHP and the tutor gave a step by step guide to setup XAMP and MySQL. I really don't know PHP but I guess source code modification is a natural skill to all programmers as I was able to modify the code to meet the requirements of the students (i.e school name, logo and other minor changes).
Most of what I learnt in programming came from modifying the source of that project. I learnt how to connect a PHP source to a MySQL database, I learnt about functions and their usage, I learnt the basics of HTML, I really learnt a lot and I would say that the speed at which I learnt was proportional to the amount of pressure I received to deliver.
That was how my journey as a full stack developer started. By chance maybe.2 -
I recently joined this big MNC after shutting down my own startup. I was trying to automate their build process properly. They were currently using grunt and I favor gulp, so I offered to replace the build process with gulp and manage it properly.
I was almost done with it in development environment and QA was being done for production.
In the meantime I was trying to fix some random bug in a chrome extension backend. I pushed some minor changes to production which was not going to affect the main site. That was in the afternoon.
This Friday my senior rushed to me. It was like he ran six floors to reach me. He asked, did you push the new build system to production, I refused. He then went to the computer nearby and opened the code.
It was Friday and I was about to leave. But being a good developer, I asked what's the problem. He told me that one complete module is down and the developers responsible for them left for the day already and are unreachable.
I worked on that module multiple times last month, so I offered my help. He agreed and we get to work.
The problem was in the Angular front end. So we immediately knew that the build process is screwed. I accidentally kept the gulp process open for anyone, so I immediately rebuilt using grunt and deployed again, but to no success.
Then I carefully analyzed all the commits to the module to find out that I was the one who pushed the change last. That was the chrome extention. I quickly reverted the changes and deployed and the module was live again. The senior asked, how did you do that? I told the truth.
He was surprised that how come that change affect the complete site too. We identified it after an hour. It was the grunt task which includes all the files from that particular module, including chrome extension in the build process.
He mailed the QA team to put Gulp in increased priority and approved the more structural changes, including more scrutiny before deployment and backup builds.
The module was down for more than 5 hours and we got to know only after the client used it for their own process. I was supposed to be fired for this. But instead everyone appreciated my efforts to fix things.
I guess I am in a good company 😉4 -

TL;DR :
"when i die i want my group project members to lower me into my grave so they can let me down one last time"
STORY TIME
Last year in College, I had two simultaneous projects. Both were semester long projects. One was for a database class an another was for a software engineering class.
As you can guess, the focus of the projects was very different. Databases we made some desktop networked chat application with a user login system and what not in Java. SE we made an app store with an approval system and admin panels and ratings and reviews and all that jazz in Meteor.js.
The DB project we had 4 total people and one of them was someone we'll call Frank. Frank was also in my SE project group. Frank disappeared for several weeks. Not in class, didn't contact us, and at one point the professors didn't know much either. As soon as we noticed it would be an issue, we talked to the professors. Just keeping them in the loop will save you a lot of trouble down the road. I'm assuming there was some medical or family emergency because the professors were very understanding with him once he started coming back to class and they had a chance to talk.
Lesson 1: If you have that guy that doesn't show up or communicate, don't be a jerk to them and communicate with your professor. Also, don't stop trying to contact the rogue partner. Maybe they'll come around sometime.
It sucked to lose 25% of our team for a project, but Frank appreciated that we didn't totally ignore him and throw him under the bus to the point that the last day of class he came up to me and said, "hey, open your book bag and bring it next to mine." He then threw a LARGE bottle of booze in there as a thank you.
Lesson 2: Treat humans as humans. Things go wrong and understanding that will get you a lot farther with people than trying to make them feel terrible about something that may have been out of their control.
Our DB project went really well. We got an A, we demoed, it worked, it was cool. The biggest problem is I was the only person that had taken a networking class so I ended up doing a large portion of the work. I wish I had taken other people's skills into account when we were deciding on a project. Especially because the only requirement was that it needed to have a minimum of 5 tables and we had to use some SQL language (aka, we couldn't use no-SQL).
The SE project had Frank and a music major who wanted to minor in CS (and then 3 other regular CS students aside from me). This assignment was make an app store using any technology you want. But, you had to use agile sprints. So we had weekly meetings with the "customer" (the TA), who would change requirements on us to keep us on our toes and tell us what they wanted done as a priority for the next meeting. Seriously, just like real life. It was so much fun trying to stay ahead of that.
So we met up and tried to decided what to use. One kid said Java because we all had it for school. The big issue is trying to make a Java web app is a pain in the ass. Seriously, there are so many better things to use. Other teams decided to use Django because they all wanted to learn Python. I suggested why not use something with a nice package system to minimize duplicating work that had already been done and tested by someone. Kid 1 didn't like that because he said in the real world you have to make your own software and not use packages. Little did he know that I had worked in SE for a few years already and knew damn well that every good project has code from somewhere else that has already solved a problem you're facing. We went with Java the first week. It failed miserably. Nobody could get the server set up on their computers. Using VCS with it required you to keep the repo outside of the where you wrote code and copy and paste changes in there. It was just a huge flop so everyone else voted to change.
Lesson 3: Be flexible. Be open to learning new things. Don't be afraid to try something new. It'll make you a better developer in the long run.
So we ended up using Meteor. Why? We all figured we could pick up javascript super easy.Two of us already knew it. And the real time thing would make for some cool effects when an app got a approved or a comment was made. We got to work and the one kid was still pissed. I just checked the repo and the only thing he committed was fixing the spelling of on word in the readme.
We sat down one day and worked for 4 straight hours. We finished the whole project in that time. While other teams were figuring out how to layout their homepage, we had a working user system and admin page and everything. Our TA was trying to throw us for loops by asking for crazy things and we still came through. We had tests that ran along side the application as you used it. It was friggin cool.
Lesson 4: If possible, pick the right tool for the job. Not the tool you know. Everything in CS has a purpose. If you use it for its purpose, you will save days off of a project.1 -
Me passing time on the weekend
Random call from unknown number
Turns out it's the manager
M: hey , how is your weekend going ...
Me: nothing much ... Whatsup ?
M : yeah well , we wanted to push some minor adhoc fixes as some clients wanted it urgently
The Devops folks need developer support . Can you pitch in and monitor
Me : I'm not aware of what changes are going , i don't think i can provide support
M : don't worry it's minor changes , it's already tested in pre prod , you just need to be on call for 30 mins
Me : ugh okay .. guess 1 hr won't hurt
M: thanks 👍🏽
Me: *logs in
*Notices the last merged PR
+ 400 lines , implemented by junior dev and merged by manager
*Wait , how is this a *minor* release...
*Release got triggered already and the CI CD pipeline is in progress
*5 mins later
*Pipeline fails , devops sends email - test coverage below 50%
Manager immediately pitches in ...
M: hey , i see test coverage is down , can you increase it ?
Me: and how do u suppose I do that ?
M : well it's simple just write UTC for the missing lines ... Will it take time ?
Me : * ah shit here we go again
Yeah it will take time , there are around 400 lines , I am not aware of this component all together
Can you ask junior dev to pitch in and write the UTC for this
*Actually junior dev is out on a vacation with his girlfriend
M : well he's out for the weekend , but
as a senior dev , i expect you to have holistic understanding of the codebase and not give excuses ,
this is a priority fix which client are demanding we need this released ASAP
Me : * wait wat ?
---
I ended up being online for next 3 hours figuring out the code change and bumping up the UTC 🤦🏾9 -
Why is it that pretty much zero package & framework maintainers understand semantic versioning?
1. If you do a complete rewrite of your package, but the resulting API is identical, you don't need to bump to the next major version. As a user, I'm thankful for your increased performance or cleaner internal code, but it doesn't really affect my update process.
2. If your package required some-framework 6.0.0, and now ALSO supports some-framework 7.0.0 but is still compatible with 6.0.0, you don't need to bump to the next major version. As a user, I can now upgrade the framework, and know that the package will keep working, but otherwise it doesn't really affect me.
3. Following your versioning along with the framework/language version is super annoying, especially if your library really doesn't need to differentiate between framework versions because it's not actually utilizing new framework functionality.
4. On the other hand, if you stop supporting a certain language, framework or shared library version, or change the public methods, exceptions, fields, etc, you MUST bump to a new major version.
Yet everyone gets this wrong.
For example, many of Laravel's underlying subpackages (for collections, filesystem, database, config, http, mail, etc) do not change their code in a breaking way, or do not even change at all between major framework versions.
Yet they follow along with the major framework version.
Now if someone makes a library "laravel-elasticsearch" which uses the support libraries and collections from laravel, they need to update their package to move along with the versions as well, and often they choose to number their library along with the framework in turn.
This means that to update the framework, you also need to update over 9000 dependencies.
FOR NO FUCKING REASON. THE ONLY CHANGE IN THOSE FUCKING DEPENDENCIES IS TO UPDATE COMPOSER.JSON TO BE COMPATIBLE WITH THE FUCKING FRAMEWORK.
Meanwhile, Laravel itself breaks repeatedly on minor/patch version updates, because breaking changes slip through their review process.
Ugh.3 -
Excerpts from "Bastard devops from hell" checklist:
- Insistently pronounce git with a soft "G" and refuse to understand people not using that pronunciation, the same goes for jithub, jitlab, jit lfs, jitkraken etc.
- Reject all pull requests not in haiku format, suggest the author needs to be more culturally open minded when offending.
- increment version numbers ONLY based on percentage code changed: Less than 1% patch increment, less than 5% minor increment, more than that major version increment.
- Cycle ALL access keys, personal tokens, connection strings etc. every month "for security reasons"
- invent and only allow usage of your own CI/CD language, for maximum reuse of course. Resist any changes to it after first draft release23 -
Okay so I have been a consumer of devRant for a while now but never posted anything. This is my first.
So yesterday I modified an existing method(some very minor changes!!). Today after coming to the office I see that I have comments from Sonarqube stating
"Reduce cognitive complexity from ** to 15.
I get that it is a good measure to maintain readability but this refactoring is not part of my change at all and any mishap can break the whole code base!!!.
My code even won't build because of this company restriction that there should not be any issues from Sonarqube.
I really want to bash my head against the wall right now.11 -
A Bad and Sad Day
Hello Monday,
Client : on weekend site went down for 7 hours? Why ?
Me : Let me check the logs
Client : bla bla bla
boss : check ur code bla bla bla
Reason : Some PHP service stopped on server
Client2 : I have purchased this software and you have to made minor changes
Me : Payment Integrations are not working?
Client : Whataa nonsense is this.. you are supposed to do this
Me : We are supposed to do minor changes. They do not have proper payment integrations. If you want we have to write complete code
Client : bla bla.. I gave you working software
:( Why don't you just fuck off .. liars2 -
There was an android project that I got from my senior.
he told me that another developer already completed most the project and all I have to do is minor changes...
Well when i saw, i was amazed that the code he commented is more than the actual working code without any structure.
He copied most of code from internet.
If it's not working, put in comment else use it.
It took me a whole month to figure out what's going on.
And another 2 months to fix the issues.
Well in last my senior told me that the developer took 1 year to write this code
(to be honest any normal developer can complete that project in less than 3 month)2 -
I can't believe this company has not hired a ux designer yet!
Team managers have no clear design principles to follow, they are coming up with design changes and ideas on the fly.
For fucks sake, at least provide a reference design or color sets to implement instead of complaining to me when i use hard colors like red / green / blue on first version of what you asked to do.
I hate doing minor style changes on code when you have no clear vision about the design.
I think the end product is gonna end up as a ux nightmare without a ux specialist.2 -
So ok here it is, as asked in the comments.
Setting: customer (huge electronics chain) wants a huge migration from custom software to SAP erp, hybris commere for b2b and ... azure cloud
Timeframe: ~10 months….
My colleague and me had the glorious task to make the evaluation result of the B2B approval process (like you can only buy up till € 1000, then someone has to approve) available in the cart view, not just the end of the checkout. Well I though, easy, we have the results, just put them in the cart … hmm :-\
The whole thing is that the the storefront - called accelerator (although it should rather be called decelerator) is a 10-year old (looking) buggy interface, that promises to the customers, that it solves all their problems and just needs some minor customization. Fact is, it’s an abomination, which makes us spend 2 months in every project to „ripp it apart“ and fix/repair/rebuild major functionality (which changes every 6 months because of „updates“.
After a week of reading the scarce (aka non-existing) docs and decompiling and debugging hybris code, we found out (besides dozends of bugs) that this is not going to be easy. The domain model is fucked up - both CartModel and OrderModel extend AbstractOrderModel. Though we only need functionality that is in the AbstractOrderModel, the hybris guys decided (for an unknown reason) to use OrderModel in every single fucking method (about 30 nested calls ….). So what shall we do, we don’t have an order yet, only a cart. Fuck lets fake an order, push it through use the results and dismiss the order … good idea!? BAD IDEA (don’t ask …). So after a week or two we changed our strategy: create duplicate interface for nearly all (spring) services with changed method signatures that override the hybris beans and allow to use CartModels (which is possible, because within the super methods, they actually „cast" it to AbstractOrderModel *facepalm*).
After about 2 months (2 people full time) we have a working „prototype“. It works with the default-sample-accelerator data. Unfortunately the customer wanted to have it’s own dateset in the system (what a shock). Well you guess it … everything collapsed. The way the customer wanted to "have it working“ was just incompatible with the way hybris wants it (yeah yeah SAP, hybris is sooo customizable …). Well we basically had to rewrite everything again.
Just in case your wondering … the requirements were clear in the beginning (stick to the standard! [configuration/functinonality]). Well, then the customer found out that this is shit … and well …
So some months later, next big thing. I was appointed technical sublead (is that a word)/sub pm for the topics‚delivery service‘ (cart, delivery time calculation, u name it) and customerregistration - a reward for my great work with the b2b approval process???
Customer's office: 20+ people, mostly SAP related, a few c# guys, and drumrole .... the main (external) overall superhero ‚im the greates and ur shit‘ architect.
Aberage age 45+, me - the ‚hybris guy’ (he really just called me that all the time), age 32.
He powerpoints his „ tables" and other weird out of this world stuff on the wall, talks and talks. Everyone is in awe (or fear?). Everything he says is just bullshit and I see it in the eyes of the others. Finally the hybris guy interrups him, as he explains the overall architecture (which is just wrong) and points out how it should be (according to my docs which very more up to date. From now on he didn't just "not like" me anymore. (good first day)
I remember the looks of the other guys - they were releaved that someone pointed that out - saved the weeks of useless work ...
Instead of talking the customer's tongue he just spoke gibberish SAP … arg (common in SAP land as I had to learn the hard way).
Outcome of about (useless) 5 meetings later: we are going to blow out data from informatica to sap to azure to datahub to hybris ... hmpf needless to say its fucking super slow.
But who cares, I‘ll get my own rest endpoint that‘ll do all I need.
First try: error 500, 2. try: 20 seconds later, error message in html, content type json, a few days later the c# guy manages to deliver a kinda working still slow service, only the results are wrong, customer blames the hybris team, hmm we r just using their fucking results ...
The sap guys (customer service) just don't seem to be able to activate/configure the OOTB odata service, so I was told)
Several email rounds, meetings later, about 2 months, still no working hybris integration (all my emails with detailed checklists for every participent and deadlines were unanswered/ignored or answered with unrelated stuff). Customer pissed at us (god knows why, I tried, I really did!). So I decide to fly up there to handle it all by myself16 -
I just finished upgrading a dotnet core 2.2 WebApi + Console App to dotnet core 3.1 and it was a very smooth process with very minor changes to my code.
Not a rant, just posting because it is the first nice thing that has happened for me in a while now.4 -
I'll tell you the only time... The only times I'll fuck up.
When something changes. That's it.
Nothing else causes me to fuck anything up.
My code gets more and more messy the more people go oh change that ,😐 can that be a capital .... Hold on that box should be smaller
😤😡 Messy = I fuck up.
Now that might well be something I need to work on !
But if you send me twenty emails all with minor things that take seconds to change 😡 I will care less about your project , that makes me lazy.
If you want your project to be perfect on launch .. one plan a couple round of amends maybe 3 and your golden
But I can not keep checking if your application is all good after these minor changes 😐 (these are not situation you can write tests for)
Yes it makes me an asshole I'm aware , but I've been awake 40 hours fixing these peoples work, and quite frankly I couldn't give a toss1 -
So while exploring some new ideas, I decided to figure out if I could use variables in the known set to determine the bounds of variables in the unknown set.
The variables in question are algebraic identities derived from the semiprimes, so you already know where this is going.
The existing known set is 1194 identities.
And there are, if I recall, roughly two dozen unknowns.
Many knowns have the unknowns as their factors. The d4 product set for example is composed of variables d4a, d4u, d4z, d4z9, d4z4, d4alpha, d4theta, d4omega, etc.
The component variables themselves are unknown, just their products are known. Anyway.
What I've found interesting is if you know the minimum of some of these subsets, for example d4z is smallest out of the d4's for some semiprimes, then you know the upperbound of both the component variables d4 and z.
Unless of course either of them is < 1.
So the order of these variables, based on value, changes depending on the properties of the semiprime, which I won't get into. Most of the time the order change is minor, but for some variables they can vary a lot between semiprimes, rapidly shifting their rank in the known set. This makes it hard to do anything with them.
And what I found myself asking, over and over again, was if there was a way to lock them down? Think of it like a giant switch board, where flipping one switch lights up N number of others, apparently at random. But flipping some other switch completely alters how that first switch works and what lights it seemingly interacts with. And you have a board of them thats 1194^2 in total. So what do you do?
I'd had a similar notion a while back, where I would measure relative value in the known set, among a bunch of variables, assign a letter if the conditions were present, and generate a string, called a "haplotype."
It was hap hazard and I wrote a lot of code to do filtering, sorting, and set manipulation to find sets of elements in common, unique elements, etc. But the 'type' strings, a jumble of random letters, were only useful say, forty percent of the time. For example if a semiprime had a particular type starting with a certain series of letters, 40% of the time a certain known variable was guaranteed to be above a certain variable from the unknown set...40%~ of the time.
It was a lost cause it seemed.
But I returned to the idea recently and revamped the entire notion.
Instead what I would approach it from a more complete angle.
I'd take two known variables J and K, one would be called the indicator, and the other would be the 'target'.
Two other variables would be the 'component' variables (an element taken from the unknown set), and the constraint variable (could be from either the known or unknown set).
The idea was that relationships between the KNOWN variables (an indicator and a target variable) could be used to indicate the rank relationship between the unknown component variable and the constraint variable.
You'd think this wouldn't work either, but my intuition was there were so many seemingly 'random' rank changes of variables in the known set for any two semiprimes, that 1. no two semiprimes ever shared the same order for every variable, and 2. the order of the known variables had to be leaking information about the relationships of the unknown variables.
It turns out my intuition was correct.
Imagine you are picking a lock, and by knowing the order and position of the first two pins, you are able to deduce the relative position of two pins further back that you can't reach because of the locks security features. It doesn't let you unlock the lock directly, but by knowing this, if you can get past the lock's security features, you have a chance of using information about the third pin to get a better, if incomplete, understanding about the boundary position of the last pin.
I would initiate a big scoring list, one for each known element or identity. And then I would check it in tandem like so:
if component > constraint and indicator > target:
indicator[j]+= 1
This is a simplication, but the idea was to score ALL such combination of relationship, whether the indicator was greater than the target at the same time a component was greater than a constraint, or the opposite.
This worked out to four if checks and four separate score lists.
And by subtracting one scorelist from another, I could check for variables that were a bad fit: they'd have equal probability of scoring for example, where they were greater than the target one time, and then lesser than it for another semiprime.
So for any given relationship, greater or lesser between any unknown variable and constraint variable, I could find any indicator variable and target variable whose relationship strongly correlated to the unknown's.18 -
Any individual project that made me learn cool stuff...
Maybe the kernelcheck project? It's a shell script that I wrote 2 years ago (it's still on my GitHub but the code looks kinda horrible tbh), and it really made me respect the stability of package managers, and the effort that package maintainers must put into it. Even a single package (the kernel) that you have to maintain the integrity of the .config for (the configuration file that tells you what options to compile in, as a module, or not at all) while on every new minor release, the config changes ever so slightly.. at some point I figured that I'd really need to do those compilations manually, to be able to supervise (and if necessary adjust) it in real-time. The ability for distribution maintainers to do this for thousands of packages.. it boggles my mind. Respect! -
Customer to me: "This should be right aligned, not left aligned. We need a fix on this 10 year old version, it's a blocker we can't do any work without it!"
Me to customer: "No. Not a blocker, minor change. We'll look at it next minor version."
Customer to boss: <repeat above>
Boss to me: "This is a blocker, check out the code and fix it today!"
FUUUUUUUUCK!
Minor stylistic changes are not goddamned fucking blockers!
I call this the "Jump; No; Boss Jump; Fuck!" effect.2 -
Fried two devices today by simply connecting them to a power source.
Changed nothing in the circuitry, no shorts due to solder residues (a simple modification was made), no changes in the input parameters. Check.
The afromentioned devices should have only minor HW changes compared to a previous version I'm working with and as far as I can see absolutely nothing which should cause the damn microcontroller to release smoke like a steam train. (All right, a very miniature steam train.)
So the only significant difference might be the firmware which I didn't check yet but will tomorrow. Not my code and the corresponding IDE just basically sucks. Yay.
On the other hand, the Software part finally feels like I'm getting somewhere. It seems just ... to work. Very suspicious.
Feeling ambivalently frustrated and relieved at the same time. Sigh.7 -

I am the technical lead in a project which uses a C# based framework. It's a lot of drag and drop, and C# scripts can be embedded for fancy stuff.
Scripts in general are not hard to do, it's harder to understand the business rules rather than the code itself.
I got hired as a junior to build this project from scratch as an MVP, and we need another junior to add enhancements and minor changes required from our end users. Since management wants me to move on working on more mid-senior development stuff, I'm supposed to be only supervising the juniors work (in the hopes that one day they'll be able to work on their own).
We've had bad luck filling this position. Our last hire is a guy like 17 years older than me, supposedly with experience in said framework but OH DEAR GOD.
Fucktard can't understand requirements and corrections, isn't able to deliver a 20 line script without fucking up. I give him a list with 3 mistakes to fix and only fixes two, crap like that.
Now, hear me out, the mistakes are stuff like:
- Unused variables
- Confusing error messages
- Error messages written in spanglish (mix between Spanish and English, we're located in Latin America)
- Untested features, this is the worst of all.
You may say "but he's a junior", sure. But as I said, he supposedly has experience, more years in IT than me, and fine, you're allowed to fuck up a few times on your first tasks but not make the same mistakes over and over, specially since we've already sat down and addressed these issues in presence of the CTO.
Fuck this guy. I genuinely dislike him as a person also, he is from another latin country and we have some serious cultural differences. For instance, he insists on sucking your ass constantly, being overly well manered (we already saluted with the whole team at the daily stand up, stop saying hello, good day, regards in each of your fucking chat messages or task submissions), and other mannerisms that are hard to translate, but whatever, all of these attitudes are frowned upon here. They're not necessary, we just want to keep it simple, cordial and casual and see you deliver the crap that you're being paid for with a decent level of quality.
On Monday the CTO comes back from vacation, I'm looking forward to that meeting, gonna report his ass, there is evidence everywhere on our issue tracker.4 -
Storytime.
Our prometheus node, one of your oldest systems (somehow fits the Titan reference..), is about to be relieved of its duties after several years of loyal services to the crew.
We decided to run with another Prometheus node in the ring, that will run simultaneously with the old one, so that the new one can start to collect metrics that we need for alerting (some historic metrics are needed too..). sort of an Prometheus cluster, without the cluster fun and with 2 different Prometheus versions.
The problems with this? Well it's not the new node or the latest shit versions of Prometheus per se.
1: The node exporter.
those dudes decided to make some breaking changes in a minor update, so that you will need to run with some magic bullshittery, that the latest Prometheus can make something out of the old metrics provided by the old node exporters.
The other one is the related puppet code.
The node definitions for Prometheus were built via exported resources on the target nodes.
The code worked like a charm with only one Prometheus node, but try that with two instances in the same way.
Still WIP, but some targets are already included in the new Prometheus instance.
alerting works so far.
Can't wait to close this ticket for good.. -

the tech market is crazy mann! it's one of the top indie fintech companies in our country and has a great valuation.
i totally felt that they i am crashing the interviews , and am seriously not trying to be humble. before the dsa round , i was trying to mug up how insertion sort works 🥲
--------
now my dilemma is should i switch if i get the offer. in a summary:
current company:
- small valuation but profitable (haven't picked funding for last 3 years , so poast valuation is some double digit million $, but can easily be a unicorn company)
- very major b2b player in my country. almost all unicorns (including this fintech company) and some major MNCs are their client and they have recently acquired a few other companies of us and eu too, making them- a decent global player
- meh work : i love being a cutting edge performer in android but here we make sdks that need to support even legacy banking apps. so tech stack is a lot of verbose java and daily routine includes making very minor changes to actual code and more towards adding tests , maintaining wrapper sdks in react/cordova/unity etc, checking client side code etc.
- awesome work life balance : since work is shit and i am fast enough, i am usually working only 2-4 hours a day. i joined gym, got into shape , and have already vsited 5 places in last 6 months, and i am a guy who didn't used to have time even on sundays. here, we get mote paid leaves than what i would usually need.
- learning opportunities: not exactly from the company codebase, but they provide unlimited access to various course learning platforms like linkedin learning, udemy and others, so i joined some web dev baches and i now know decent frontend too. plus those hybrid sdks also give a light context to new things
new company :
- positives : multi billion valuation, one of the top players in fintech , have been mostly profitable ( except a few quarters)
- positive : b2c so its (hopefully) going to put me back into racing shoes with kotlin, jetpack and latest libraries.
- more $$$ for your boy :)
- negetive : they seem to be on hiring spree and am afraid to junp ship after seeing the recent coinbase layoffs. fintech is scary these days
- negetive : if they are hiring people like me, then then they are probably hiring people worse than me 😂. although thats not my concern what my main concer is how they interviewed. they have hired a 3rd party company that takes interviews of people FOR THEM! i find that extremely impolite, like they don't even wanna spare their devs to hire people they are gonna work with. i find this a toxic, robotic culture and if these are the people in there then i would have a terrible time finding some buddy engineer or some helpful senior.
- negetive : most probably a bad wlb : i worked for an year for a fast paced b2c edtech startup. no matter how old these are , b2c are always shipping new stuff and are therefore hectic. i don't like the boredom here but i would miss the free time to workout :(
so ... any thoughts about it?4
