LONG RANT AHEAD!

In my workplace (dev company) I am the only dev using Linux on my workstation. I joined project XX, a senior dev onboarded me. Downloaded the code, built the source, launched the app,.. BAM - an exception in catalina.out. ORM framework failed to map something.

mvn clean && mvn install

same thing happens again. I address this incident to sr dev and response is "well.... it works on my machine and has worked for all other devs. It must be your environment issue. Prolly linux is to blame?" So I spend another hour trying to dig up the bug. Narrowed it down to a single datamodel with ORM mapping annotation looking somewhat off. Fixed it.

mvn clean && mvn install

the app now works perfectly. Apparently this bug has been in the codebase for years and Windows used to mask it somehow w/o throwing an exception. God knows what undefined behaviour was happening in the background...

Months fly by and I'm invited to join another project. Sounds really cool! I get accesses, checkout the code, build it (after crossing the hell of VPNs on Linux). Run component 1/4 -- all goocy. run component 2,3/4 -- looks perfect. Run component 4/4 -- BAM: LinkageError. Turns out there is something wrong with OSGi dependencies as ClassLoader attempts to load the same class twice, from 2 different sources. Coworkers with Windows and MACs have never seen this kind of exception and lead dev replies with "I think you should use a normal environment for work rather than playing with your Linux". Wtf... It's java. Every env is "normal env" for JVM! I do some digging. One day passes by.. second one.. third.. the weekend.. The next Friday comes and I still haven't succeeded to launch component #4. Eventually I give up (since I cannot charge a client for a week I spent trying to set up my env) and walk away from that project. Ever since this LinkageError was always in my mind, for some reason I could not let it go. It was driving me CRAZY! So half a year passes by and one of the project devs gets a new MB pro. 2 days later I get a PM: "umm.. were you the one who used to get LinkageError while starting component #4 up?". You guys have NO IDEA how happy his message made me. I mean... I was frickin HIGH: all smiling, singing, even dancing behind my desk!! Apparently the guy had the same problem I did. Except he was familiar with the project quite well. It took 3 more days for him to figure out what was wrong and fix it. And it indeed was an error in the project -- not my "abnormal Linux env"! And again for some hell knows what reason Windows was masking a mistake in the codebase and not popping an error where it must have popped. Linux on the other hand found the error and crashed the app immediatelly so the product would not be shipped with God knows what bugs...

I do not mean to bring up a flame war or smth, but It's obvious I've kind of saved 2 projects from "undefined magical behaviour" by just using Linux. I guess what I really wanted to say is that no matter how good dev you are, whether you are a sr, lead or chief dev, if your coworker (let it be another sr or a jr dev) says he gets an error and YOU cannot figure out what the heck is wrong, you should not blame the dev or an environment w/o knowing it for a fact. If something is not working - figure out the WHATs and WHYs first. Analyze, compare data to other envs,... Not only you will help a new guy to join your team but also you'll learn something new. And in some cases something crucial, e.g. a serious messup in the codebase.

The network starts slowing down, transactions start to fail across the 450+ stores, the website starts to spit 500 errors what is going on?

Queue a frantic running around the office working out what was going wrong... Calls from all 3 data centres, nothing is going in or out of the network.

Notice the network admin come back to his desk, his eyebrows raise and he looks left and right before unplugging his laptop ethernet from one of the server access points

The network rushes back to life, everything is fine.

That particular network mapping tool is now banned for use on production.

Why not have a custom (500 line) JSON mapper... you know... fuck those auto mapping libraries out there...

After work I wanted to come home and work on a project. I have a few ideas for a few things I want to do, so I started a Trello board with the ideas to start mapping things out. But there were guys redoing the kitchen tile and it was noisy as fuck. So I packed up and headed to the library.

So I get all set up, and start plugging away. Currently working on a database design for a project that is a form for some user data collection for my dad, for an internal company thing. I am not contracted for this - I just know the details so I am using it as a learning exercise. Anyway...

I'm fucking about in a VM in MySQL and I feel someone behind me. So I turn and it's this girl looking over my shoulder. She asks what I am doing, and it turned into a 2 hour conversation. She is only a few years older than me (21) but she was brilliant. She (unintentionally) made me feel SO stupid with her scope of knowledge and giant brain. I learned quite a bit from talking to her and she offered to help me further, if I liked.

And she was really cute. We exchanged phone numbers...

I messaged a professor at MIT and surprisingly got a response back.

He told me that "generating primes deterministically is a solved problem" and he would be very surprised if what I wrote beat wheel factorization, but that he would be interested if it did.

It didnt when he messaged me.

It does now.

Tested on primes up to 26 digits.
Current time tends to be 1-100th to 2-100th of a second.

Seems to be steady.

First n=1million digits *always* returns false for composites, while for primes the rate is 56% true vs false, and now that I've made it faster, I'm fairly certain I can get it to 100% accuracy.

In fact what I'm thinking I'll do is generate a random semiprime using the suspected prime, map it over to some other factor tree using the variation on modular expotentiation several of us on devrant stumbled on, and then see if it still factors. If it does then we know the number in question is prime. And because we know the factor in question, the semiprime mapping function doesnt require any additional searching or iterations.

The false negative rate, I think goes to zero the larger the prime from what I can see. But it wont be an issue if I'm right about the accuracy being correctable.

I'd like to thank the professor for the challenge. He also shared a bunch of useful links.

That ones a rare bird.

Books and command lines.

I don't like teachers.

I think it's because my learning process is very async and chaotic. When I see a snippet in Golang, I relate it to PHP, Rust and Haskell. I jump to resolving the problem in other languages, trying to find out which approaches work in Go.

Then I read about some computer science concept on Wikipedia and get lost in that while my hunger for knowledge and food increases. After a while I look up a recipe for a pasta salad, and while cutting bell peppers, I see the recipe in terms of typed morphisms, I sprinkle and intersperse ingredients through mapping functions, then decide to write an interpreter for the esoteric "Chef" language in Go so I can interpret my salad recipe while eating it.

Voila, I'm learning Go.

I have no patience for linear mentoring, and others have no patience for mentoring me.

But that's OK.

I built a custom web app for my wife.
She uses Adwords all day long and there mapping tool for radiuses sucks, so I wanted it to be easier for her.
She ended up letting her co-workers use it too, and they love it.
It has copy and paste functionality so that you can save the custom map and open it later.
Today, one of her co workers accidentally emailed a link to this custom web app to a client. He opened the link, and declared it to be the best thing since sliced bread.

Unfortunately, not my client, not my job ... so, it really doesn’t mean much for my career. But it did make me feel good.
Thinking maybe create account functionality and start selling subscriptions. Could be a few extra bucks a month. Lol.

I am a student. A Geospatial Engineering student. I made a demo Cordova app mapping incident spots on OSM., now my fellow undergrads think I can hack NSA, program a satellite, build all their dream websites and apps. The College Department wants me to lead an in-house photogrammetric programmable drone project. If they ask I'll say yes... yes I can! shit.😂

this is how I destroyed my career in IT and how I'm headed to a bleak future.

I've spent the last 10 years working at a small company developing a web platform. I was the first developer, I covered many roles.
I worked like crazy, often overtime. I hired junior dev, people left and came. We were a small team.
I was able to keep the boat afloat for many years, solving all the technical problems we had. I was adding value to the company, sure, but not to mine professional career.

There was a lot of pressure from young developers, from CEO, from investors. Latent disagreement between the COO and the CEO. I was in between.
Somehow, the trust I built in 10 years, helping people and working hard, was lost.

There was a merge, development was outsourced, the small team I hired was kept for maintenance and I was fired, without obvious explanations.Well, I was the oldest and the most expensive.

Now I'm 53, almost one year unemployed.
I'm a developer at heart, but obsolete. The thing we were doing,
were very naif. I tried to introduce many modern and more sophisticated software concepts. But basically it was still pure java with some jquery. No framework. No persistency layer, no api, no frontend framework. It just worked.

I moved everything to AWS in attempt to use more modern stack, and improving our deployment workflow.
Yes, but I'm no devop. While I know about CD/CI, I didn't set up one.

I know a lot of architectural concepts, but I'm not a solution architect.

I tried to explain to the team agile. But I'm not a scrum master.
I introduced backlog management, story mapping, etc. But I'm not a product manager.

And before that? I led a team once, for one year, part of a bigger project. I can create roadmap, presentations, planning, reports.
But I'm not a project manager.

I worked a lot freelancing.
Now I'll be useless at freelancing. Yes I understand Angular, react, Spring etc, I'm studying a lot. But 0 years of experience.
As a developer, I'm basically a junior developer.

I can't easily "downgrade" my career. I wish. I'll take a smaller salary. I'll be happy as junior dev, I've a lot to learn.
But they'll think I'm overqualified, that I'll leave, so they won't hire me even for senior dev. Or that I won't fit in a 25 y.o. team.

My leadership is more by "example", servant leader or something like that. I build trust when I work with somebody, not during a job interview.

On top of that, due to having worked in many foreign countries, and freelancing, my "pension plan" I won't be able to collect anything. I've just some money saved for one year or so.

I'm 53, unemployed. In few years time, if I don't find anything, it will be even harder to be employed.

I think I'm fucked

Hey I got reminded of a funny story.

A friend of mine and me were in internships in the same company. The company was specialized in territory resources management (managing water for agriculture, money to build industrial zones...). He got the interesting internship (water predictory modeling) and I got... The repairs of a reference sheet manager that never happened to work. It was in C# and ASP.NET and I was in second year of CS. I expected the code to be nice and clear since it was made by a just graduated engineer with +5years of studies.

I was very wrong.

This guy may never have touched a web server in his life, used static variables to keep sessions instead of... well... sessions, did code everything in the pages event handlers (even LinQ stuff et al) and I was told to make it maintainable, efficient and functional in 2 months. There were files with +32k LoC.

After 1week of immense despair, I decided I will refactor all the code. Make nice classes, mapping layer, something close to a MVC... So I lost time and got scoled for not being able to make all the modifications as fast as in a cleanly designed code...

After 4 weeks, everything was refactored and I got to wait for the design sheets to change some crystal report views.

At this moment I began to understand were was the problem in this company.

My friend next door got asked to stop his modeling stuff for an emergency project. He had to make an XML converter for our clients to be able to send decentralized electrics bills, and if it was not completed within a week, they would no longer be able to pay until it is done.

This XML converter was a project scheduled 5 years before that. Nobody wanted to do it.

At the same time, I was waiting for the Com Department to give me the design views.

I never saw the design views. Spent one month implementing a golden ratio calculator with arbitrary precision because they ain't give me anything to do until the design were implemented.

Ended with a poor grade because "the work wasn't finished".

Git gets easier once you understand branches are homeomorphic endofunctors mapping submanifolds of a Hilbert space.

boss: we should map all the possible ways to do things in the system so we can test them and make sure we fix the bugs.

Me: yeah, well, that is exactly what automated tests are for, every time we find a non-mapped way that breaks this we make a test out of it and fix, this ways we end up mapping the majority of ways.

Boss: yeah,yeah ... Let's sit down latter and map everything on a document.

I bet my ass we are never gonna have tests as a part of our workflow.

Everyone talks about their hate of js but like python is honestly just as bad.

- shitty package manager,
* need to recreate python environments to keep workflows seperate as oppose to just mapping dependencies like in maven, npm, cargo, go-get
* Can't fix python version number to project I.e specify it in requirements
- dynamic typing that gets fixed with shitty duck typing too many times
- no first class functions
- limited lambda expressions
- def def def
- overly archaic error messages, rarely have I gotten a good error message and didn't have to dive into package code to figure it out
- people still use 2.7 ... Honestly I blame the difficulty of changing versions for this. It's just not trivial to even specify another python version
- inconsistent import system. When in module use . When outside don't.
- SLOW so SLOW
- BLOCKING making things concurrent has only recently got easier, but it still needs lots of work. Like it would be nice to do

runasync some_async_fcn()
Or just running asynchronous functions on the global scope will make it know to go to some default runtime. Or heck. Just let me run it like that...

- private methods aren't really private. They just hide them in intelisense but you can still override them....

I know my username is ironic :P

Entity Framework Core Mapping LOL

Sometimes I really fucking hate this company

The code is an absolute shitshow filled with static classes, untestable and duplicate code, on top of that my boss doesn’t like open source

Yeah so i’m not allowed to use a mapping library or something because “Uhhh like uhh we don’t have a contract with the company so who knows what’ll happen when the maintainers leave the project”
I understand his reasoning but it’s an absolutely retarded reasoning especially considering most of the .NET platform is open source nowadays

Writing a webapp from scratch now as well and I HAVE to use vanilla javascript and AngularJS 1.5 even though all the developers here told me they would like to upgrade to Typescript and Angular 2+ but it’s never gonna happen I suppose

Oh and he doesn’t like TDD and our only product is SAAS so imagine the amount of bugs being pushed simply because we don’t have time to write tests or even manually test, let alone refactor our horseshit codebase

AND i have to pay for gas myself which takes 200€ out of my bank account a month just for driving to work whilst I’m only getting a mediocre pay

Have a job interview tomorrow and another one on tuesday

I feel like my legacy has begun. I hear people using a notation description that I think that I invented.

When one does port mapping in commands it is like this: 5432:5432. Nobody remembers which port comes first unless they the command a lot. I confidently referred to it as "reverse cotton eyed joe notation" in a meeting.

"Where do you go? Where do you come from Cotton eyed joe?"

Me and that other guy who has a braincell: Okay so we made this simple object mapping code so that you have the option to use YAML or environment variables, because they're both awesome UwU (we use YAML for testing, then variables for container prod deployments).

Some dude who picked up the project: meh, lets ditch that, dotenv and get rid of the object mapping, because I like to do the pain manually.

AND THIS DUDE NEVER EVEN BOTHERED TO READ THE CODE CLAIMING HIS IS BETTER WTF

It took us enough testing and cofusion to get Object Mapping right and this guy just bastardizes work we've done for the past 2 years claiming "it sucks"

What a bloody bellend.

I finally fucking made it!

Or well, I had a thorough kick in my behind and things kinda fell into place in the end :-D

I dropped out of my non-tech education way too late and almost a decade ago. While I was busy nagging myself about shit, a friend of mine got me an interview for a tech support position and I nailed it, I've been messing with computers since '95 so it comes easy.

For a while I just went with it, started feeling better about myself, moved up from part time to semi to full time, started getting responsibilities. During my time I have had responsibility for every piece of hardware or software we had to deal with. I brushed up documentation, streamlined processes, handled big projects and then passed it on to 'juniors' - people pass through support departments fast I guess.

Anyway, I picked up rexx, PowerShell and brushed up on bash and windows shell scripting so when it felt like there wasn't much left I wanted to optimize that I could easily do with scripting I asked my boss for a programming course and free hands to use it to optimize workflows.

So after talking to programmer friends, you guys and doing some research I settled on C# for it's broad application spectrum and ease of entry.

Some years have passed since. A colleague and I built an application to act as portal for optimizations and went on to automate AD management, varius ssh/ftp jobs and backend jobs with high manual failure rate, hell, towards the end I turned in a hobby project that earned myself in 10 times in saved hours across the organization. I felt pretty good about my skills and decided I'd start looking for something with some more challenge.

A year passed with not much action, in part because I got comfy and didn't send out many applications. Then budget cuts happened half a year ago and our Branch's IT got cut bad - myself included.

I got an outplacement thing with some consultant firm as part of the goodbye package and that was just hold - got control of my CV, hit LinkedIn and got absolutely swarmed by recruiters and companies looking for developers!

So here I am today, working on an AspX webapp with C# backend, living the hell of a codebase left behind by someone with no wish to document or follow any kind of coding standards and you know what? I absolutely fucking love it!

So if you're out there and in doubt, do some competence mapping, find a nice CV template, update your LinkedIn - lots of sources for that available and go search, the truth is out there!

Client:we want dynamic mapping of network and packet flow visualization like;packet tracer simulation
Us: is 2D visualization enough.
Client:yeah
*fast forward after first demo*
Client: now make it 3D with pipes representing cable.and packets flowing through them like water.
Me: fucccccck

Inspired by @Billgates

everyone around is hyped about new tech they get to use, new toys to tinker with, I can see their eyes shining when they hear "let's try and introduce kafka" - they would wiggle their tails all day long if they had ones!

And me? Well, a new potential employer got me so excited I couldn't wash a smile off my face for a few days! You know what they said? "we don't use any frameworks, we focus on clean code, solid, kiss and we write with tdd". Bare java - that's the best position I've heard of in years!

I guess I'm oldschool. But I truly believe their approach is the right one. Not trashing the code with spring [which is turning into smth what systemd is for linux/unix], hibernate and what not.

Just good old java code. Db, multithreading, request-mapping -- all plain, manual and simple.

Amazing!

The joys of mapping...
I'm playing around with some cartographer parameters and this happened. Thought it fits the christmas theme and was kindas beautiful so decided to share.
It's a map snowflake :3

So I am conducting an introductory seminar on git and GitHub for juniors and as per my knowledge I've drafted this outline, please add your inputs..

The seminar will be of 1 day only

1. Install and configure Git and Github

2. Digital Signature mapping

3. Git init

4. New Project with HTML

5. Configure remote (git remote add <origin> <url>) ends with .git

6. Git commit (git commit –m “Title” –m “commit message”)

7. Pushing git push (git remote push origin master)

8. Git commit –amend

9. Git pull (git pull origin master)

10. Git checkout (git checkout –b new_branch_name)

11. Do some changes

12. Git push new branch (git remote push origin new_branch_name)

13. Git switch branch (git checkout <name_of_existing_branch>)

14. Pull requests

15. Git log (git log –oneline –graph)

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.

A friend of mine once buried an exception deep in some code that any reasonable programmer shouldn't ever come across that said "you're the worst person I know"

A few days later when a guy in our project was working on his awful patchwork of a database mapping he managed to somehow actually hit this exception. We all got a good laugh out of it!

Trying to answer a React mapping problem on stackoverflow.
It's a relatively simple problem.
While I'm typing... all sorts of wrong answers keep popping out.

Oh geez.
People are hungry for reputation

In the end, I removed my solution, and leave the answer in the comment. This is not my fight 🤦‍♂️

This is something I'm proud of about myself as a developer, which is rare.

My setup with the Alt key.

All the keys in my left hand (as in, for all the keys in my left hand region, qwerasdfzxcv)
have their Alt and AltShift combinations mapped to (almost) all the special chars related to programming.
For example:
Alt + z -> /
AltShift + z -> \

Here's me typing them in 2 seconds.
{}()_-'"/:+=<>[]|#~`\;*!

And, on my right hand, I emulate the arrow keys movement:
Alt + hjkl moves chars
AltShift + hjkl moves and selects chars
AltCtrl + hjkl moves words
AltCtrlShift + hjkl moves and selects words
Alt + n. backspaces/deletes chars
AltCtrl + n. backspaces/deletes words

And the best of them all:
Alt + space -> <return>
AltShift + space -> Shift+<return> (which does a newline in chat editors like fb messenger)
AltCtrl + Space -> Ctrl+<return> (which can do the submit in some forms, like send email in gmail)

Now, my hand sits for real on the home row and rarely moves because it's not there just for vim, but for the entire system as well.
This setup is very compliant with my little mouse use, since I use vim, and the vim extension for chrome.
I still use and need the mouse for some tasks.

Another one huge benefit is that I don't have a problem remembering where the keys are. This is a problem I can have because I go between different keyboards because of having used different keyboards: argentinian, american, japanese and now brazilian (I'm not trying to be cool, it's just a series of circumstances that led me to using different keyboards).

At the same time, this thing might have become a hinderance because it's not as easy for me going to a different keyboard.

Regarding implementations, when I used MacOS I used Karabiner, insanely clean interface.
On linux, I have to create my own mapping in X.

True quote :
A full stack developer uses jsonlint more than an IDE.

:(

Writing coroutines for io_uring. Submissions aren't working (they go through but the operation never seems to complete). Just fixed a few segfaults because of error cases not destroying coroutine handles correctly. Been on this for two days, finding more and more things I need to do that unrelated to the task at hand. Don't have issue tracking set up yet because haven't had time. Mountain of things that need to get working just for a demo is only growing. Layered maps of data structures and code flow are in my head as I'm trying to mentally debug some of this. I'm focused, completely dead to the outside world.

Then I feel a small scratch on my cheek. Three hours of mental mapping and a deep stack of thought, vanishes into thin air in a single moment.

The trade-off is worth it though.

As a junior developer it's frustrating to not have the skill yet of mentally mapping data models in your head, so that you can figure out bugs.

I see senior developers being able to quickly solve bugs because they can translate code into data models and they can figure out what's wrong.

Me on the other hand, I spend hours and days with my hands in my hair trying to figure out why my algorithm isn't giving me back what I expect it to.

It'll take experience.. I only have 1 year experience..

My Final Year Project used robotics, speech recognition, body mapping and it was possibly the coolest thing I've ever done. I did it to be balls out ambitious as I wanted an impressive project to help me get a job...

I agree with many people on here that Front-End web development/design isn't what it used to be.

Things used to be simple: a static page. Then we decoupled design from description and we introduced CSS; nice, clean separation, more manageable - everything looks nice up to this point.

Introduce dynamic pages, introduce JavaScript. We can now change the DOM and we can make interactive, neat little webpages; cool, the web is still fun.

Years later, we start throwing backend concepts into the web and bloating it with logic because we want so much for the web to be portable and emulate the backend. This is where it starts to get ugly: come ASP, come single pages, partial pages, templates,.. The front-end now talks to a backend, okay. We start decoupling things and we let the logic be handled by the backend - fair enough.

Even later, we start decoupling the edge processes (website setup, file management, etc.) and then we introduce ugly JavaScript tools to do it. Then we introduce convoluted frameworks (Angular,..). Sometimes we find ourselves debugging the tools themselves (grunt, gulp, mapping tools,..) rather than focusing on the development itself (as per ITIL guidelines; focus on value), no matter how promising today's frameworks claim to be ("You get to focus on your business code"; yeah right, in practice it has turned out differently for me. More like "I get to focus on wasting copious amounts of time trying to figure out your tangled web").

Everything has now turned into an unfriendly, tangled web (no pun intended).

I miss the old days when creating things for the Web used to be fun, exciting and simple and it would invigorate passion, not hate.

<my cents="2"></my>

My God is map development insane. I had no idea.

For starters did you know there are a hundred different satellite map providers?

Just kidding, it's more than that.

Second there appears to be tens of thousands of people whos *entire* job is either analyzing map data, or making maps.
Hell this must be some people's whole *existence*. I am humbled.

I just got done grabbing basic land cover data for a neoscav style game spanning the u.s., when I came across the MRLC land cover data set.

One file was 17GB in size.

Worked out to 1px = 30 meters in their data set. I just need it at a one mile resolution, so I need it in 54px chunks, which I'll have to average, or find medians on, or do some sort of reduction.

Ecoregions.appspot.com actually has a pretty good data set but that's still manual. I ran it through gale and theres actually imperceptible thin line borders that share a separate *shade* of their region colors with the region itself, so I ran it through a mosaic effect, to remove the vast bulk of extraneous border colors, but I'll still have to hand remove the oceans if I go with image sources.

It's not that I havent done things involved like that before, naturally I'm insane. It's just involved.

The reason for editing out the oceans is because the oceans contain a metric boatload of shades of blue.
If I'm converting pixels to tiles, I have to break it down to one color per tile.
With the oceans, the boundary between the ocean and shore (not to mention depth information on the continental shelf) ends up sharing colors when I do a palette reduction, so that's a no-go. Of course I could build the palette bu hand, from sampling the map, and then just measure the distance of each sampled rgb color to that of every color in the palette, to see what color it primarily belongs to, but as it stands ecoregions coloring of the regions has some of them *really close* in rgb value as it is.

Now what I also could do is write a script to parse the shape files, construct polygons in sdl or love2d, and save it to a surface with simplified colors, and output that to bmp.

It's perfectly doable, but technically I'm on savings and supposed to be calling companies right now to see if I can get hired instead of being a bum :P

I often read articles describing developer epiphanies, where they realized, that it was not Eclipse at fault for a bad coding experience, but rather their lack of knowledge and lack of IDE optimization.

No. Just NO.

Eclipse is just horrendous garbage, nothing else. Here are some examples, where you can optimize Eclipse and your workflow all you like and still Eclipse demonstrates how bad of an IDE it is:

- There is a compilation error in the codebase. Eclipse knows this, as it marks the error. Yet in the Problems tab there is absolutely nothing. Not even after clean. Sometimes it logs errors in the problems tab, sometimes t doesn't. Why? Only the lord knows.

- Apart from the fact that navigating multiple Eclipse windows is plain laughable - why is it that to this day eclipse cannot properly manage windows on multi-desktop setups, e.g. via workspace settings? Example: Use 3 monitors, maximize Eclipse windows of one Eclipse instance on all three. Minimize. Then maximize. The windows are no longer maximized, but spread somehow over the monitors. After reboot it is even more laughable. Windows will be just randomly scrabled and stacked on top of each other. But the fact alone that you cannot navigate individual windows of one instance.. is this 2003?

- When you use a window with e.g. class code on a second monitor and your primary Eclipse window is on the first monitor, then some shortcuts won't trigger. E.g. attempting to select, then run a specific configuration via ALT+R, N, select via arrows, ALT+R won't work. Eclipse cannot deal with ALT+R, as it won't be able to focus the window, where the context menus are. One may think, this has to do with Eclipse requiring specific perspectives for specific shortcuts, as shortcuts are associated with perspectives - but no. Because the perspective for both windows is the same, namely Java. It is just that even though Shortcuts in Eclipse are perspective-bound, but they are also context-sensitive, meaning they require specific IDE inputs to work, regarldless of their perspective settings. Is that not provided, then the shortcut will do absolutely nothing and Eclipse won't tell you why.

- The fact alone that shortcut-workarounds are required to terminate launches, even though there is a button mapping this very functionality. Yes this is the only aspect in this list, where optimizing and adjusting the IDE solves the problem, because I can bind a shortcut for launch selection and then can reliably select ant trigger CTRL+F2. Despite that, how I need to first customize shortcuts and bind one that was not specified prior, just to achieve this most basic functionality - teminating a launch - is beyond me.

Eclipse is just overengineered and horrendous garbage. One could think it is being developed by people using Windows XP and a single 1024x768 desktop, as there is NO WAY these issues don't become apparent when regularily working with the IDE.

I think the sleep deprived me is finally cracking under the weight of incompetent assholes.

We just launched a major project in some weird cocktail of Agile slapped with MVP and release to the wild in a waterfall, but it was premature, premature in the sense QA hasn't even finished their side of things, but because some fuck with with "manager" in their title decided they have burnt through the budget with incompetence and scrapped an entire element of the project and outsourced just so they could make a shittier version that doesn't even fucking work.

How hard do you want to fail before you will start listening to the people that now have to work around the fucking clock to clean up this horse shit of a mess.

I'm literally arguing over field mapping with multiple 3rd parties, when the fucking requirements state WTF this is suppose to look like. All because they didn't validate or test their own shit.

Why is EVERY FUCKING cock head in this industry a waste of space and cash! Is it really to much to ask for 1 fucking project to fucking go live that actually fucking works where I don't need to work 2 weeks straight (including weekends) after going live just to be sure that what shit does hit the fan isn't going to create a SEV 1 issue...

Sorry, I'm pissed at the incompetence of others I need to deal with on a daily basis. It's not like this field is insanely hard. A little attention to detail and self validation, verification goes a long way. But clearly that's a rarity.

Once this shit is stable and actually works, I'll be pulling out the mop to clean up half this shit just so it actually works.

Oof, I'm getting to old for this bullshit.

Spending hours trying to figure out why the stack just won't work with SSL. Nearly lost my mind as we started feeling dumber than ever. I really started to doubt my skills after it did not even work with the most minimal nginx site config I could imagine.
The next day I discovered that we missed the 443 port mapping in the docker-compose file...it only had port 80 mapped.

Yup, stepping back from a problem and getting some sleep is really worth it sometimes.

Apple's idea of innovation - 2017: AR mapping your face to a poop emoji

Honestly, they shouldn't have bothered with this, and release something great next year.

When your boss thinks a mapping company needs to make a bot...😓

Just bought a knockoff controller for my gaming PC, plugged it in and I was playing Rocket League in 10 seconds. No driver install, no key mapping.

This is how everything should be.

I'm considering quitting a job I started a few weeks ago. I'll probably try to find other work first I suppose.

I'm UK based and this is the 6th programming/DevOps role I've had and I've never seen a team that is so utterly opposed to change. This is the largest company I've worked for in a full time capacity so someone please tell me if I'm going to see the same things at other companies of similar sizes (1000 employees). Or even tell me if I'm just being too opinionated and that I simply have different priorities than others I'm working with. The only upside so far is that at least 90% of the people I've been speaking to are very friendly and aren't outwardly toxic.

My first week, I explained during the daily stand up how I had been updating the readmes of a couple of code bases as I set them up locally, updated docker files to fix a few issues, made missing env files, and I didn't mention that I had also started a soon to be very long list of major problems in the code bases. 30 minutes later I get a call from the team lead saying he'd had complaints from another dev about the changes I'd spoke about making to their work. I was told to stash my changes for a few weeks at least and not to bother committing them.

Since then I've found out that even if I had wanted to, I wouldn't have been allowed to merge in my changes. Sprints are 2 weeks long, and are planned several sprints ahead. Trying to get any tickets planned in so far has been a brick wall, and it's clear management only cares about features.

Weirdly enough but not unsurprisingly I've heard loads of complaints about the slow turn around of the dev team to get out anything, be it bug fixes or features. It's weird because when I pointed out that there's currently no centralised logging or an error management platform like bugsnag, there was zero interest. I wrote a 4 page report on the benefits and how it would help the dev team to get away from fire fighting and these hidden issues they keep running into. But I was told that it would have to be planned for next year's work, as this year everything is already planned and there's no space in the budget for the roughly $20 a month a standard bugsnag plan would take.

The reason I even had time to write up such a report is because I get given work that takes 30 minutes and I'm seemingly expected to take several days to do it. I tried asking for more work at the start but I could tell the lead was busy and was frankly just annoyed that he was having to find me work within the narrow confines of what's planned for the sprint.

So I tried to keep busy with a load of code reviews and writing reports on road mapping out how we could improve various things. It's still not much to do though. And hey when I brought up actually implementing psr12 coding standards, there currently aren't any standards and the code bases even use a mix of spaces and tab indentation in the same file, I seemingly got a positive impression at the only senior developer meeting I've been to so far. However when I wrote up a confluence doc on setting up psr12 code sniffing in the various IDEs everyone uses, and mentioned it in a daily stand up, I once again got kickback and a talking to.

It's pretty clear that they'd like me to sit down, do my assigned work, and otherwise try to look busy. While continuing with their terrible practices.

After today I think I'll have to stop trying to do code reviews too as it's clear they don't actually want code to be reviewed. A junior dev who only started writing code last year had written probably the single worst pull request I've ever seen. However it's still a perfectly reasonable thing, they're junior and that's what code reviews are for. So I went through file by file and gently suggested a cleaner or safer way to achieve things, or in a couple of the worst cases I suggested that they bring up a refactor ticket to be made as the code base was trapping them in shocking practices. I'm talking html in strings being concatenated in a class. Database migrations that use hard coded IDs from production data. Database queries that again quote arbitrary production IDs. A mix of tabs and spaces in the same file. Indentation being way off. Etc, the list goes on.
Well of course I get massive kickback from that too, not just from the team lead who they complained to but the junior was incredibly rude and basically told me to shut up because this was how it was done in this code base. For the last 2 days it's been a bit of a back and forth of me at least trying to get the guy to fix the formatting issues, and my lead has messaged me multiple times asking if it can go through code review to QA yet. I don't know why they even bother with code reviews at this point.

Work on a Python mapping project, get everything right except changing color of points on the map. Take a long break on that project, come back and realize I made a capitalization error 😂😂

On the days when I just want to sob and put my head through the monitor....

I get out a piece of paper and draw my processes (whether that be code or mapping etc). Each step of each process, helps to represent the input and output of each method.

This makes it easier to find which step isn't giving the desired output....

Either this or the rubber duck method. :)

anyone tried source engine (hammer) on linux?

Just finished a app for mapping printers based purely on convention in a Citrix environment, no manual config needed. Chief of operations said "it's fixing stuff like this that should trigger a bonus, too bad we're the government". (Yay, thanks for rubbing it in).
Then I responded "I'll get my reward in heaven as usual, then". CIO says: "but you're not going there...."

Guess I just need a fire extinguisher then. Thanks boss.

Allright, so now I have to extend a brand new application, released to LIVE just weeks ago by devs at out client's company. This application is advertised as very well structured, easy to work on, µservices-based masterpiece.

Well either I lack a loooot of xp to understand the "µservices", "easy to work on" and "well structured" parts in this app or I'm really underpaid to deal with all of this...

- part of business logic is implemented in controllers. Good luck reusing it w/o bringing up all the mappings...
- magic numbers every-fucking-where... I tried adding some constants to make it at least a tiny bit more configurable... I was yelled at by the lead dev of the app for this later.
- crud-only subservices (wrapped by facade-like services, but still.. CRUD (sub)services? Then what's a repository for...?). As a result devs didn't have a place where they could write business logic. So business logic is now in: controllers (also responsible for mapping), helpers (also application layer; used by controllers; using services).
- no transactions wrapping several actions, like removing item from CURRENT table first and then recreating it in HISTORY table. No rollback/recovery mechanism in service layers if things go South.
- no clean-code. One can easily find lines (streams) 400+ cols long.
- no encapsulation. Object fields are accessed directly
- Controllers, once get result from Services (i.e. Facade), must have a tree of: if (result instanceof SomeService.SomeSubservice1.Item1) {...} else if (result instanceof SomeService.SomeSubservice2.Item4) {...} etc. to build a proper DTO. IMO this is not a way to make abstraction - application should NOT know services' internals.
- µservices use different tables (hats off for this one!) but their records must have the same IDs. E.g. if I order a burger and coke - there are 2 order items in my order #442. When I make a payment I create an invoice which must have an id #442. And I'm talking about data layer, not service or application (dto)! Shouldn't µservices be loosely coupled and be able to serve independently...? What happens if I reuse InvoiceµService in some other app?

What are your thoughts?

So I came from the Portal modding scene. And I know most other ones who did similar stuff.
Now there was a cool looking upcoming free mod and I somehow came in touch with the lead Dev. Now somehow I managed to get into the developer team and me and my girlfriend we're part of it. We got a level name and should start mapping it (TL;DR, we never finished one because we didn't know what to do).

I actually made a website for the mod. But sometime later we both left the team because the lead Dev (12 yo btw) was "hiring" (working for passion not money btw, that's fine in this case) everyone he got in touch with. They had no team structure just a huge list of people and a long story script. I'd guess the mod won't ever be done, although it has made it through steam greenlight (R.I.P greenlight). Just because they're not working on a team.

A project that is used across our company with multiple clients. It's huge, over 2million lines of code and 116 separate projects. Not a single piece of documentation. Took me three weeks to track down where the authentication occurred with visual debugging and mapping tools.

I can see life is meaningless and the only reason of my short visit to this planet is to pass on my vain selfish genes.

But what drives me every day is the exponential trends of tech and the looming technological singularity in the 2040s. And the prospect of staying alive for billions of years mapping exoplanets, contributing in every way I can.

Until we reach a Type 10 civilization and beyond, I'm not sure when I might want to hang up my coat.

Still if I can't make it to the singularity, that's cool also, after all life is meaningless.

I'm chill with anything.

Not shouting and yelling at the client. Something along the lines of:
"The data has changed because of a mapping table chance you fucking signed off last fucking November!
And no I can't provide data that's not in the source system - which orifice exactly would you like me to get it from?!?"

#sigh# much better....

Me writing articles: …so think of Brodal-Okasaki heap as a set of endofunctors mapping the N-dimensional Hilbert continuum, simple as that
Me talking on stage: how is babby formed

!rant.

I fucked up. Recently I applied for a job in Intel. All questions they throw at me I answered well, but there's one question that f**ked me hard that I can't think of any answer to. (Because ! am not familiar with this)

I was questioned about SLAM ( Simultaneous localization and mapping), I am new to this.

Now I think I failed to get the job. Therefore, I f**ked up

FUCK rabbit holes real hard. When you spend a week creating a super optimized recursive handler for mapping redundant database row results and you wake up from your coma realizing everything could be handled by a much simpler SQL query done in five minutes. Fuck me, fuck the rabbits creating holes to fall into and fuck Alice for creating the fucking illusion of wonderland.

Some Java code I looked through to figure out how to accurately rework a mapping of value intervals to status colors:

• 16 levels of indentation
• Calls an instance method one line before a null-check
• Assigns that same value to a new variable and null-checks it again
• Insistently loops over existing HashMaps' entry sets to find a value by key
• Stringifies a Gson object, parses back the string and then null-checks the result.
• Mixes up the 'leq' and 'geq' comparison operators twice, which is why I went to check the implementation in the first place.

And this wasn't even legacy code. It's from last year.

was working on a project once where we needed a database mapping to some c# code
tasked one of our less experienced guys on it to maybe give him some experience

now I'm assuming most people here who have worked in .NET for a reasonable amount of time know about entity framework, and I did tell the guy about it.

three days after giving him that task he comes up to me smiling and says he's done

great! what did he do? he wrote the database mapping from scratch using hard coded SQL queries using lists to chain queries together in a sea of if-else statements...

let's just say the code broke down and needed last minute fixing when it was time to present it

I work on a small team, and we recently got an artist on it.

The artist has lights on, but nobody is home syndrome and it is driving me nuts.

This guy took 10 iterations on a model where the main request was to fucking change the fucking UV mapping. Here is how that went in a nutshell:

1. Hey, the model is ok, the guy needs a cape with some bones in it. The cape needs to share the material, here is the material, cape already on it. We also need like 8 animations.
1a. No cape visible, animations half done, and done shitty.
2. Correct the animations and all the above points asap. Ok?
2a. Few more animations 1 half corrected wrong, wonky exports. Has cape
3. Again, same.
3a. I got the wrong corrections, cape doesn,t move. Uv wrong and seperate material. Aaaarrrggg

It litterally took 7 more of those loops and now we have it going in 1 material and 5 wonky but workable animations. And the next character half of the same shit happens all over again. Fuck me, fuck him. Fuck this, i hate artists. I made a fucking list what is so hard?!

Today there was a question on the react native forum asking how to map an array..... ([].map(mapFunction))

1) it's the wrong place for the question

2) like 80% mentioned ramda, lodash, underscore :(

I have just started to use mind mapping SW, but wonder > where is the possibility of backlinks?? only forward?! :-|

DynamoDbMapper ISSUE

There were multiple pojos which maps with one of our DynamoDb table with slightly different schema (leveraging nosql).

For one of the pojos, while populating one of the attributes, it was always throwing some weird exception and no one had any idea about it.
An intern was assigned to fix it in case some new pair of eyes can observe something weird about the pojo.

Later, I realized that the way DynamoDbMapper behaves inside a pojo is very particular and hidden.
A method was declared as public instead of private in the pojo, and DynamoDbMapper while mapping the pojo to the table with reflection, it said that this attribute (a substring of the method name) cannot be converted.

Finally, it was just a single word change from PUBLIC TO PRIVATE.

I used to be proud of my skills using eclipse IDE, then I decided to try IDEA. No regrets, but after 3 months I still not mastered the new key mapping and totally forgot the eclipse one. Now I have no reason to change back at all xD

So, I work as a sysadmin junior (6 months and going), and in the past few months, I learned what my boss warned me about - Devs don't understand us admins, and we don't understand the devs.

We have this huge client who is about to migrate to our company (We do mostly server managment/Housing/Renting), and I am so gald I don't have to work on the migration myself!

Just hearing what the company devs say makes me facepalm: No, it won't work. It cannot work on just 3 machines (They use like... 20 in total), no, we won't get rid of our docker swarm, that's essential (Doing the absolute minimum in their infrastructure, just a fancy buzzword to lure people on. Though they've spent like 2 years developing the app that uses it, so they my not want to give it up).

I kid you not, once, they replied to an email that contained the phrase "To be afraid of/worried about" something during the migration, that something could break, not work, be unstable. 7 times.

Might not sound as bad, but it was a rather short mail, and when they're so afraid of everything, its kinda hard to cooperate with them.

My colleague literally spent this entire week mapping out /their/ infrastructure, because they were unable to provide us with the description themselves.

And as a cherry on top, they sent us a "graph" of relationships of all the parts of their infrastructure that was this jumbled mess of rectangles and arrows. Oh, and half of all the machines were not even in the graph at all! Stating that "We also have all this, but I really don't know how to ilustracte the interactions anymore"

Why do companies like that exist? If you build an infrastructure yourself, shouldn't at least someone know exactly how it works?

I'm not really a developer... but my Mum and Dad did both say "You are managing servers and coding? You are a geographer? Not a computer Scientist?" x

What am I supposed to do with this much whiteboard?

Trees -> declarative programming

Loops -> functional programming

Sequences -> imperative programming

Graphs -> dynamic programming

Good mapping, yeah or no?

It should be possible to prove the collatz conjecture by mapping the unit digit transitions between numbers, namely into a finite state machine. From there we could use predicates and quanitifiers to prove, by process of exclusion, that for any given combination of 10s digit and 1s digit, no number can transition to anything but whats specified in the state machine assuming that number equals x in x3+1 or x/2

Ipso facto, a series of equations proving by process of elimination, that state machines transitions are the only allowable ones, would prove the collatz conjecture by proving the fsm is a valid representation for any given integer N.

I'm actually working on it now but I don't know enough about modular arithmetic and predicate logic to write a proof. I just have the state diagrams on some dot matrix paper at the moment.

If anyone wants to beat me to it, feel free.

So for example any number ending in 13, will, after x3+1, end in 40.

Any number ending in 40 will end in 20. Any number ending in 20 will end in 10, which will end in 5 as the unit digit.

It's easier to prove in the single digit case, and the finite state machine for that is already written, at least on paper.

I'll post pictures when I get a chance.

TLDR: RTFM...

My dad (taught me how to code when I was a kid) was stuck serializing a Java enum/class to XML.... The enum wasn't just a list of string values but more like a Map(String,Object>.

He tried to annotate it with XMLEnum but the moment I saw this enum, I'm thinking that's unlikely to work.... Mapping all that to just a string?

He tried annotating the Fields in it using XMLAttribute but clearly wasnt working...

Also he use XMLEnumValue but from his test run I could clearly see it just replaced whatever the enum value would've been with some fixed String...

Me: Did you read the documentation or when the javadocs?

Dad: no, I don't like reading documentation and the samples didn't work.

I haven't done XML Serialization for years thought did use JSON and my first instinct was... You need a TypeAdapter to convert the enum to a serializable class.

So I do some Googling, read the docs then just played around with the code, figured out how to serialize a class and also how to implement XmlTypeAdapter.... 20 mins ...

Text him back with screenshots and basically:

See it's not that hard if you actually read up on the javadocs and realized ur enum is more like a class so probably the simple way won't work...

Disclamer: I don't want to give out what app I am talking about, so all names will be random to just represent the nonsense and my frustration.

So I was working with that app's API....
To begin with, some retrieved Objects have collection (iterable structure) of "Thing" objects, called "Things". But... there can be max one element in that particular collection!
Ok... I get it... I might exaggerate a bit... fine, let it be.
I had to mention it for the further part, and also got to mention that "Thing" objects are globally available and predefined, and Objects can only choose one, unused "Thing".

To the point.
Someone thought it would be good to separate representation of one structure into two classes.

We have collection of "A" objects ("As"), which have "Name", "Things" and other, mostly GUI/config related attributes.
Collection "Bs", of "B" objects, they have "Name" and rather lower-level attrs.
The "As" and their attributes can be set in the GUI, but the list where you do it is named "List of Bs" and vice versa.
Interesting, huh?

I had to use both "A" and "B" definition for given name, so I tried to map it... and things gone South.

Collecions have "Get" method with name as an argument.
But it turns out that while the "A" use its GUI name all the time, "B" uses either name that can be found in "As" or, if not all "Thing" objects are used, the "Thing" names.

Example:
global "Things" = "t0", "t1"

"As" = "a0"("t0"), "a1"("t1") -> "Bs" == "a0", "a1"
"As" = "a0"("t0"), "a1"() -> "Bs" == "a0", "t1"
"As" = "a0"(), "a1"() -> "Bs" == "t0", "t1"

That means if at least one of "A" objects have empty "Things", then the mapping will fail.

Only solution is that the app works only partially when any of "A"'s "Things" is empty, so I might raise error too, but I have to provide solution that will work even in the cases when the app don't care... so... not gonna happen.

So my boss wants this mssql reference table editor. Where you point it at references table containing mapping references and it will build a pretty gui for editing the table.... and they want it in like 3 days... so I now either hack something together which is so tightly coupled to the scheme of the table it will require redevelopment each time a new reference table needs adding to be edited or I don't deliver on time and give them a solution which will understand the schema and build the exit view dynamically... I'm starting to hate these stupid deadlines! And to top it all off they justify it with stuff like "it's just an edit view!?!?" Or recently on a basic form I created it was "why do you need to write c#? It's just a HTML form!?"

When creating a new indie game with no budget start really really small. Because it will grow faster than you can say 'input mapping'.

I just realised I have 1TB of MS OneDrive Cloud space lying around unused. DAMNNN!!!

Just yesterday, I was thinking of backing up all my content to cloud (because just in case and past experiences of losing data).

I did a quick fact check and figured that I have ~450 GB of unbacked data.

After quick calculations, I came to a number of how many Google accounts I'll need for 15 GB per account of drive space.

Today, I was playing around with my Microsoft Developer account and saw OneDrive. I thought let's check how much free space does MS Dev subscription offers.

It showed 1024 GB. FUCK! My balls dropped.

Now here's what I did...

I have a local drive of 500 GB, which holds all the unbacked data. Now I setup my local OneDrive there and put everything into OneDrive.

And then, I moved my local Google Drive into OneDrive. A nested setup for important stuff.

So this way, less important stuff is backed up on cloud and accessible everywhere.

And more important stuff gets synced on Google Drive and OneDrive, both.

Did I do the right and sensible thing with this kind of setup?

MS Developer subscription says they expire it in 90 days but until today, they have auto renewed it always.

I still have ~500 GB of space which can be consumed.

Also, overall MS ecosystem seems much better to me than Google. Moreover, MS allows custom domain mapping which Google doesn't.

Let's see how can I entirely migrate to MS ecosystem in near future.

Good old Arc Online. A truly well engineered piece of software.

Super solar power plants around the earth to powering robots and factories producing equipment to search and research more efficient energy sources across the universe and mapping the whole ma'fucka resource wide would be a nice project to spend some days at.

The CloudWatch API is an awkward piece of shit.
No convenient way to just ask for the latest value of a metric. Gotta supply a time window and hope metrics were actually reported within that window.

Oh and make sure your timestamps are in ISO 8601 or the request will fail (but the SDK does zero validation so a unit test won’t catch it of course).

Oh and you have to assign an arbitrary ID to each metric query in your request even if you don’t care about mapping the results back to the queries. And the regex for the ID is just fussy enough to be mildly irritating.

I fucking hate entity framework.
It turns 10 mins of work into fucking hours of stress and bloat and shit.

It’s the one thing in dotnet that I cannot fucking stand.

Literally did a bit of work in 10 mins (using ef I might add), but because it’s not the”ef way” I need to create an extra table/class and then fuck about mapping the relationship in a complicated way to do what I had just done in only a few lines of code with one table.

Spend over an hour trying to get it to understand the relationship before I gave up for the day. Fuck it

Wow spent another 20-25 mins mapping out the stack calls to see why varchar was trying to be converted to Nchar which isn't supported and found in my mapper class one fucking method had rs.getNString() which I swear I never touched the mapper class since I made it and was working just fine!!!! I swear IntelliJ is straight up fucking with me

Sadly took me a little longer than I’d like to admit to go from well placed print statements to using a debugger. Granted there are times when print statements are needed, but for all the devs out there who are using an IDE with a perfectly good debugger and yet doesn’t use it... please use it. It literally gives you a mapping of all objects and data types around a break point that you can easily glance at to speed up debugging. Go figure!

I literally don't understand the purpose of a "higher half kernel"

What does it matter where my kernel is mapped in virtual memory?
"It is traditional and generally good to have your kernel mapped in every user process" what the hell does that even mean??

Mapping my kernel into userspace is something is explicitely don't want to do. Like at all. Ever

And in physical memory it matters even less where it is.

I'm so confused right now

soooooo we are still trying to make the mapping from the classes to hibernate, almost 7 hours and all the time every change we do, we have to close netbeans and open it again to "refresh" the hibernate configuration ._. we have seen the netbeans logo all the f*cking night ._.

Client: "Actually I don't want that feature."

Oh man I sure do love having three separate code generators in one project with some additional hand written versions of the data containers so that every time the system engineers decide we need to change something about a data structure I have to update 1-3 hand written mapping functions. (Kill me please)

Pardon my ignorance but is what I'm trying to do even possible?

I have a WordPress network and have domain mapping setup. So the original was domainA.com/map and the new is domainB.com. Is there a way for me to keep both the old sub directory and new domain without redirects.

If not oh well.

What's a good book to learn ELK hands-on?

I have an instance set up and working but want to need some more advanced features? like mapping, index templates, querying remotely for aggregations.

The Elastic docs feel very high level and maybe assumes u can read their minds... A lot of snippets I just go "uhm.. where do I put this in the file, which file?"

I had to contact technical support for an API. I’m pretty sure I was emailing with a bot because I was getting all sorts of stupid replies.

Me: I’m using your SDK for language X. It’s returned null for some properties. In the user portal, I can see there are values for those properties for the transaction. I don’t know why I’m not receiving them on my end.

Tech Support: Hi! I see the following was sent in the API response. [Sends api response to me.] You can also go the the portal to see those values.

Me: Yeah, I know. You just repeated everything I wrote to you. I don’t want to go to the portal. I told you I want to figure out why your SDK doesn’t seem to map those properties correctly when I receive the api response.

TS: Let me look at the docs. I think you need to send the properties you want in your request in order to get them back in the reply from the api. Such as <property>value<property> in the xml message.

🤨 The docs do not say that. They don’t even imply that.

Me: What the fuck?! That makes absolutely no sense. We have already established that the api **is** returning values for those properties. I want to troubleshoot why your SDK is mapping them as NULL.

some recent discoveries of mine:

- DOS FDISK has totally-undocumented CLI (partitioning with auto-format and OTF drive mapping... like one OEM used it for their machine recovery discs and no one else even knows it exists) docs coming soon (this is a lie i found this a year or two ago but forgot till yesterday)

- nuitka is a fucking blessing and the man who made it deserves so much love for it

- my existence is one massive waste of time

- apparently some B450 boards require you to hit a button and test your fans' min/max values and it takes like an hour and IT STILL DOESN'T MAKE THEM VISIBLE FROM THE OS ASROCK YOU FUCKS

- the new Ryzen took my latest project's compile time from 30 hrs to like 6 because I can compile 12 things at once instead of just 4

- installing debian sucks ass now, they forgot to push part of apt to the 10.3 stable installer so you just can't install shit through apt until you fix that, though dpkg works

- apparently they pushed a grub-efi-amd64 version that breaks all efivars??? i know debian sid is like meant to be unstable but a bug like that should never have even been rolled into a package till it was fixed like ???????????

- depression sucks ass

Implement a rest API for elasticsearch.
Follow the client's index's mapping.
Generate json document from Java pojos, given by the client.
Jsons don't match the schema mapping, one (at least) field, for geographic coordinates, is in another format.
Ask the client for explanation.
Client response, after 6 hours:
"We build it in this shape so you have to convert them to another format before posting into ES".
What the hell is wrong with you?!

I've been given two months to make an AR app that gives information on buildings seen out of the window of a client's skyscraper office.

So off I go, smash together some Ar.js in a few days because it looks easy. Yet I quickly find out that the compass on mobile phones are completely trash. Every device I try has true north randomly chosen from anywhere between 10 degrees wrong or full on 180 degrees the opposite direction. It's a miracle that none of these devices have managed to stumble onto true north by luck. I'm getting suspicious that ar.js is actually just mapping coordinates based on north instead of true north or something ridiculous. This likely won't be helped by GPS interference from the skyscraper.

It isn't helped that ar.js is a steaming pile of bugs on top of bugs, many of the examples taken straight from documentation straight up don't work.

I'm trying to get ar.js with three.js now in the hope that I can figure out some kind of true north calibration controls as an offset to whatever the phone says north is.

If anyone has any suggestions for a better solution that would be grand.

Let's do a story mapping session! Ok cool. PO asks the team: so guys what do you think? *silence*... *more silence*.... PO: come on guys, please respond. *silence*.... Then someone finally responds.

I'm starting to hate this big time. It's almost always like that, no matter the type of session (story mapping, refinement) And there's someone in the team that thinks he always knows best, so if ever someone speaks up, it will always be challenged and lead to useless discussions. He always wants the perfect solution. A good solution is good enough, it doesn't have to be perfect. PO is happy with a good solution (good = maintainable, scoring at least x on our code quality tooling), so why the fuck would you want to go for the 'perfect' solution, which may score just slightly higher in regard to quality, cost much more to develop and people have a hard time maintaining it due to the high level of abstraction? He's always refactoring stuff because it's not future proof. Well, why completely reimplement parts that have been working properly for 2 years and have a very very small chance of needing a change, which then still only needs to be done in just 1 place?

And you know what? All these fancy structures, patterns etc are in there but will their flexibility ever really be used? In my 20 years experience haven't seen such flexibility being really used. Some exceptions of course.

Once it's built, it will keep running, yes, changes will need to be made, but in most cases they never touch all these expensive fancy structured components. Just because most changes are in content or small changes in functionality.

Who asked for RedDatabase and RedXpert? You guessed it - nobody 😑 It's a buggy Firebird and DBeaver domestic knock-off!

My student was assigned with making Flask app by "simple" requirements. But guess what? We can't figure out hecking RedDatabase?! Figures out that they sent incompatible *.fdb database file, on which we wasted entire 3 hours troubleshooting obscure error, while clean database doesn't cause any trouble.

Last error that completely drained us is following:
"""
Reason: unsupported on-disk structure for file /var/rdb/test.fdb; found 12.3, support 12.2; IProvider::attachDatabase failed when loading mapping cache [SQLState:HY000, ISC error code:335544379]
"""

So now, he basically recreates database by scheme on image. What also shady seems to me is that application also has to deployed on virtual OS which he can bring on USB stick or by cloud later.

Why are collabs dead on devrant? Im desperate to find someone to join my mapping project for 50/50 deal. Where can I find interested person?

Perforce just deleted all my work from yesterday and today. Apparently using the 'update branch mapping' feature is a bad idea

Does anyone know any good object-object property mapping library for JavaScript / Typescript? Similar to AutoMapper in C#?

Fuck testcomplete, fuck having to spend 40 minutes mapping out every element just to still hang 5 minutes every time you try to check the existence of one, fuck having a software who's sole purpose is to automate testing and save time take hours upon hours to do what a person can do in seconds, and fuck me for having to use this piece of shit to test every single change made to our site.

I just had to convince another "senior" dev that Magic Numbers are bad. Her argument was that the API already knows the mapping so creating another mapping on the front end was overkill and not needed when you know the value you need to compare against.

I am taking too long to think for final year cs project.
Thinking of autonomous mapping and exploration using UAVs
Any suggestions?

For some reason I always have a hard time mentally mapping "asc/desc" to dates. I think of stairs and mentally map the dates to unicode timestamps. Am I the only one? Sort descending by date is newest first, btw

I try map my Capslock key to ctrl key while using vim and I search for this on stackoverflow and I found

```Linux? With X, use xmodmap to alter the key mapping, e.g.

xmodmap -e 'clear Lock' -e 'keycode 0x42 = Escape'
Will map Esc to the CapsLock key. Google for more examples.```

following command it will map Esc key to CapsLock key but when I run this command my CapsLock key did stop working and nor my esc key map to CapsLock key. How do I get back my Capslock key default working state, I mean I don't want to map Capslock key to ctrl key?

Make an ASP .NET application for job interview take home assignment.

Try to use docker with it.

Runs fine through Visual studio (not code)

I declare is working and submit to organization but say it can run through docker-compose up.

I get reply that even the basic command doesn't work.

Turns out visual studio does some magic mapping or caching under the hood that I couldn't find in any config in the project and somehow gets it to work, but when running without Visual studio it doesn't have that magic context shit and thus running through terminal fails.

Obviously a lot is my fault for assuming what works through IDE would run through terminal without testing, but I will be angry with VS to make myself feel better >.>

fn key is the most evil shit key from hell
no matter where you put it, there is no layout in which you don't keep hitting it instead of something else.. It's not like you need most of the F# keys anyway you can just as well have the functional keys without this abomination.. or here's one: how about making a fucking mapping hm? To inventor of fn key: "You can suck my balls!"

I'm not sure who the fuck implemented the error handling of spring boot but goddamn he/she needs to be fired. Why the fuck does the application return a weird error about a setting not being set when it can't connect to a database?? Wtf took an hour to solve and that's not the only thing I hate about spring boot. Why is the documention utter garbage, why do I have to rely on tutorials and can't I just read in the documentation how for example the http rest mapping works. Now I have to cross-reference multiple tutorials to find the best way because guess what there are multiple ways to do something in this framework and some tutorials don't even work.

Has anyone worked with these 2 APIs
°Chargebee
°Billbee

I'm using chargebee for creating invoices
with a AWS lambda passing invoice data from chargebee to billbee to create an order in billbee
I'm in need of help on how to get item SKU
and on which side do i extract SKU
the SKU value is necessarily for mapping products in billbee when the order is created

Why the fzck do you release new features in your engine and change how port-mapping works but don't make your deployment tool compatible? I look at you docker!

Need a bit of help and I think the simple answer would've been to RTFM more carefully but yea.... Kinda late now.

I'm looking for the installers for Chromium 74.0.3707.0. I should've written form the download link but I forgot you can't just look it up with this version number.

Hence my problem. I went on the site and somehow need to lookup a revision version like 54321. But I can't find the mapping for it... Closest I got it's going the commit hash but then what...

Can anyone suggest a good opensource or free app for dependency mapping?
I have a large monolithic django application with lot of apps and I want to study each app's imports and dependency. This also can help me remove cyclic dependencies.

jQuery is a fucking garbage of the 21st century. Endless ugliest ever mapping of html element values to JSON and back. Every fucking time.

Please let me know if I m doing something wrong while parsing the data to JSON. Also, I am looking for examples to do data masking and run some SQL within Apache Beam

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

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

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

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

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

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

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

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

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

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

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

(tldr: are foriegn keys good/bad? Can you give a simple example of a situation where foriegn keys were the only and/or best solution?)

i have been recently trying to make some apps and their databases , so i decided to give a deeper look to sql and its queries.

I am a little confused and wanted to know more about foreign keys , joins and this particular db designing technique i use.

Can anyone explain me about them in a simpler way?
Firstly i wanted to show you this not much unheard tecnique of making relations that i find very useful( i guess its called toxi technique) :
In this , we use an extra table for joining 2 tables . For eg, if we have a table of questions and we have a table of tags then we should also have a table of relation called relation which will be mapping the the tags with questions through their primary IDs this way we can search all the questions by using tag name and we can also show multiple tags for a question just like stackoverflow does.

Now am not sure which could be a possibile situation when i need a foriegn key. In this particular example, both questions and tags are joined via what i say as "soft link" and this makes it very scalable and both easy to add both questions and new tags.

From what i learned about foriegn keys, it marks a mandatory one directional relation between 2 tables (or as i say "hard a to b" link)
Firstly i don't understand how i could use foriegn key to map multiple tags with a question. Does that mean it will always going to make a 1to1 relationship between 2 tables( i have yet to understand what 11 1mant or many many relations arr, not sure if my terminology is correct)

Secondly it poses super difficulty and differences in logics for adding either a tag or question, don't you think?
Like one table (say question) is having a foreign key of tags ID then the the questions table is completely independent of tag entries.

Its insertion/updation/deletion/creation of entries doesn't affect the tags table. but for tag table we cannot modify a particular tag or delete a tag without making without causing harm to its associated question entries.
if we have to delete a particular tag then we have to delete all its associated questions with that this means this is rather a bad thing to use for making tables isn't it?

I m just so confused regarding foriegn keys , joins and this toxi approach. Maybe my example of stack overflow tag/questions is wrong wrt to foreign key. But then i would like to know an example where it is useful
