I'm drunk and I'll probably regret this, but here's a drunken rank of things I've learned as an engineer for the past 10 years.
The best way I've advanced my career is by changing companies.
Technology stacks don't really matter because there are like 15 basic patterns of software engineering in my field that apply. I work in data so it's not going to be the same as webdev or embedded. But all fields have about 10-20 core principles and the tech stack is just trying to make those things easier, so don't fret overit.
There's a reason why people recommend job hunting. If I'm unsatisfied at a job, it's probably time to move on.
I've made some good, lifelong friends at companies I've worked with. I don't need to make that a requirement of every place I work. I've been perfectly happy working at places where I didn't form friendships with my coworkers and I've been unhappy at places where I made some great friends.
I've learned to be honest with my manager. Not too honest, but honest enough where I can be authentic at work. What's the worse that can happen? He fire me? I'll just pick up a new job in 2 weeks.
If I'm awaken at 2am from being on-call for more than once per quarter, then something is seriously wrong and I will either fix it or quit.
pour another glass
Qualities of a good manager share a lot of qualities of a good engineer.
When I first started, I was enamored with technology and programming and computer science. I'm over it.
Good code is code that can be understood by a junior engineer. Great code can be understood by a first year CS freshman. The best code is no code at all.
The most underrated skill to learn as an engineer is how to document. Fuck, someone please teach me how to write good documentation. Seriously, if there's any recommendations, I'd seriously pay for a course (like probably a lot of money, maybe 1k for a course if it guaranteed that I could write good docs.)
Related to above, writing good proposals for changes is a great skill.
Almost every holy war out there (vim vs emacs, mac vs linux, whatever) doesn't matter... except one. See below.
The older I get, the more I appreciate dynamic languages. Fuck, I said it. Fight me.
If I ever find myself thinking I'm the smartest person in the room, it's time to leave.
I don't know why full stack webdevs are paid so poorly. No really, they should be paid like half a mil a year just base salary. Fuck they have to understand both front end AND back end AND how different browsers work AND networking AND databases AND caching AND differences between web and mobile AND omg what the fuck there's another framework out there that companies want to use? Seriously, why are webdevs paid so little.
We should hire more interns, they're awesome. Those energetic little fucks with their ideas. Even better when they can question or criticize something. I love interns.
sip
Don't meet your heroes. I paid 5k to take a course by one of my heroes. He's a brilliant man, but at the end of it I realized that he's making it up as he goes along like the rest of us.
Tech stack matters. OK I just said tech stack doesn't matter, but hear me out. If you hear Python dev vs C++ dev, you think very different things, right? That's because certain tools are really good at certain jobs. If you're not sure what you want to do, just do Java. It's a shitty programming language that's good at almost everything.
The greatest programming language ever is lisp. I should learn lisp.
For beginners, the most lucrative programming language to learn is SQL. Fuck all other languages. If you know SQL and nothing else, you can make bank. Payroll specialtist? Maybe 50k. Payroll specialist who knows SQL? 90k. Average joe with organizational skills at big corp? $40k. Average joe with organization skills AND sql? Call yourself a PM and earn $150k.
Tests are important but TDD is a damn cult.
Cushy government jobs are not what they are cracked up to be, at least for early to mid-career engineers. Sure, $120k + bennies + pension sound great, but you'll be selling your soul to work on esoteric proprietary technology. Much respect to government workers but seriously there's a reason why the median age for engineers at those places is 50+. Advice does not apply to government contractors.
Third party recruiters are leeches. However, if you find a good one, seriously develop a good relationship with them. They can help bootstrap your career. How do you know if you have a good one? If they've been a third party recruiter for more than 3 years, they're probably bad. The good ones typically become recruiters are large companies.
Options are worthless or can make you a millionaire. They're probably worthless unless the headcount of engineering is more than 100. Then maybe they are worth something within this decade.
Work from home is the tits. But lack of whiteboarding sucks.37 -
Buffer usage for simple file operation in python.
What the code "should" do, was using I think open or write a stream with a specific buffer size.
Buffer size should be specific, as it was a stream of a multiple gigabyte file over a direct interlink network connection.
Which should have speed things up tremendously, due to fewer syscalls and the machine having beefy resources for a large buffer.
So far the theory.
In practical, the devs made one very very very very very very very very stupid error.
They used dicts for configurations... With extremely bad naming.
configuration = {}
buffer_size = configuration.get("buffering", int(DEFAULT_BUFFERING))
You might immediately guess what has happened here.
DEFAULT_BUFFERING was set to true, evaluating to 1.
Yeah. Writing in 1 byte size chunks results in enormous speed deficiency, as the system is basically bombing itself with syscalls per nanoseconds.
Kinda obvious when you look at it in the raw pure form.
But I guess you can imagine how configuration actually looked....
Wild. Pretty wild. It was the main dict, hard coded, I think 200 entries plus and of course it looked like my toilet after having an spicy food evening and eating too much....
What's even worse is that none made the connection to the buffer size.
This simple and trivial thing entertained us for 2-3 weeks because *drumrolls please* none of the devs tested with large files.
So as usual there was the deployment and then "the sudden miraculous it works totally slow, must be admin / it fault" game.
At some time it landed then on my desk as pretty much everyone who had to deal with it was confused and angry, for understandable reasons (blame game).
It took me and the admin / devs then a few days to track it down, as we really started at the entirely wrong end of the problem, the network...
So much joy for such a stupid thing.18 -
Everyone and their dog is making a game, so why can't I?
1. open world (check)
2. taking inspiration from metro and fallout (check)
3. on a map roughly the size of the u.s. (check)
So I thought what I'd do is pretend to be one of those deaf mutes. While also pretending to be a programmer. Sometimes you make believe
so hard that it comes true apparently.
For the main map I thought I'd automate laying down the base map before hand tweaking it. It's been a bit of a slog. Roughly 1 pixel per mile. (okay, 1973 by 1067). The u.s. is 3.1 million miles, this would work out to 2.1 million miles instead. Eh.
Wrote the script to filter out all the ocean pixels, based on the elevation map, and output the difference. Still had to edit around the shoreline but it sped things up a lot. Just attached the elevation map, because the actual one is an ugly cluster of death magenta to represent the ocean.
Consequence of filtering is, the shoreline is messy and not entirely representative of the u.s.
The preprocessing step also added a lot of in-land 'lakes' that don't exist in some areas, like death valley. Already expected that.
But the plus side is I now have map layers for both elevation and ecology biomes. Aligning them close enough so that the heightmap wasn't displaced, and didn't cut off the shoreline in the ecology layer (at export), was a royal pain, and as super finicky. But thankfully thats done.
Next step is to go through the ecology map, copy each key color, and write down the biome id, courtesy of the 2017 ecoregions project.
From there, I write down the primary landscape features (water, plants, trees, terrain roughness, etc), anything easy to convey.
Main thing I'm interested in is tree types, because those, as tiles, convey a lot more information about the hex terrain than anything else.
Once the biomes are marked, and the tree types are written, the next step is to assign a tile to each tree type, and each density level of mountains (flat, hills, mountains, snowcapped peaks, etc).
The reference ids, colors, and numbers on the map will simplify the process.
After that, I'll write an exporter with python, and dump to csv or another format.
Next steps are laying out the instances in the level editor, that'll act as the tiles in question.
Theres a few naive approaches:
Spawn all the relevant instances at startup, and load the corresponding tiles.
Or setup chunks of instances, enough to cover the camera, and a buffer surrounding the camera. As the camera moves, reconfigure the instances to match the streamed in tile data.
Instances here make sense, because if theres any simulation going on (and I'd like there to be), they can detect in event code, when they are in the invisible buffer around the camera but not yet visible, and be activated by the camera, or deactive themselves after leaving the camera and buffer's area.
The alternative is to let a global controller stream the data in, as a series of tile IDs, corresponding to the various tile sprites, and code global interaction like tile picking into a single event, which seems unwieldy and not at all manageable. I can see it turning into a giant switch case already.
So instances it is.
Actually, if I do 16^2 pixel chunks, it only works out to 124x68 chunks in all. A few thousand, mostly inactive chunks is pretty trivial, and simplifies spawning and serializing/deserializing.
All of this doesn't account for
* putting lakes back in that aren't present
* lots of islands and parts of shores that would typically have bays and parts that jut out, need reworked.
* great lakes need refinement and corrections
* elevation key map too blocky. Need a higher resolution one while reducing color count
This can be solved by introducing some noise into the elevations, varying say, within one standard div.
* mountains will still require refinement to individual state geography. Thats for later on
* shoreline is too smooth, and needs to be less straight-line and less blocky. less corners.
* rivers need added, not just large ones but smaller ones too
* available tree assets need to be matched, as best and fully as possible, to types of trees represented in biome data, so that even if I don't have an exact match, I can still place *something* thats native or looks close enough to what you would expect in a given biome.
Ponderosa pines vs white pines for example.
This also doesn't account for 1. major and minor roads, 2. artificial and natural attractions, 3. other major features people in any given state are familiar with. 4. named places, 5. infrastructure, 6. cities and buildings and towns.
Also I'm pretty sure I cut off part of florida.
Woops, sorry everglades.
Guess I'll just make it a death-zone from nuclear fallout.
Take that gators!5 -
I have been working on this software for 3 years now. The code base was a working prototype made by my boss before I came, not more, not less. Php + Angular. Have been refactoring a lot, backend is backed with hundreds of tests now, frontend still lacks a lot. Still a lot of programm structures are still the same weird ones my boss once created in a rush between two meetings while learning Angular to get the prototype finished. Now it's used in production which makes hard to refactor, because we have to maintain backwards compatibility. Neither the parts I added or refactored completely are satisfying, because they are built on this structures, because i never got any feedback for anything I decided and because I changed my own paradigms over time.
So I am all alone on this project. All genuinly new projects are assigned to the new team members (i was the first one, no we are five plus my boss) because I wont have time, have to maintain the old one. So I never can do something new which is quite frustrating.
I did a little side tool, the only thing I invented and did completely by myself in our repertoire - and now some stakeholder shows big interest onto this. Instead of giving me the task to make a real project from this my boss wants to give it to them to develop it. Why? Because I need more time for the main application.
Also the more the software is used the more bug tickets and feature requests come. I was crying for help for months but the others had appareantly more important stuff to do.
This might be true to some extend. Yesterday we had some kind of crisis meeting and my boss wanted again to assing pur junior to help me, who has a shit load of other things to do and is a student. I insisted that this would not be enough, and one of the fulltime devs has to get involved because the thing is our core application and I am only part time btw. So my boss said we wont decide today but one of them should do it. They should have some time to figure out who which is understandable but it's not that I didn't keep saying this for months. Now they are all like whimp whimp when I have to do php i will quit. The new projects are all typescript, with node backend if any. But alas, one of them even said yesterday he doesn't want to do js anymore. Okay... but... this is our tech stack then get another job allready?
And I should do the same probably. But then again I feel very sorry for my boss who helped me in very dark times of corona and more. If both of us leave, the project he worked on for decade (including convincing poeole, collect money..) might be suddenly at it's end while he is so exited about it's access today...
I also get insecure if it's really that they hate php so much or that they don't want to work with me personally because maybe I am a bad team Player or what?
I experienced the same at my old workplace, got left alone with big parts of the project because they didn't want to do php and js in this case and it ended up five devs doing the python backend and me doing the frontend and the php cms part all alone. Then I quit and now everything seems to happen again.
And then again I think I am only fucked up so hard by this stuff because I do not really like being a developer at all. I only do it for the money and because I am good at it (at least i think so. Nobody ever bothers to ever to read my code and give me feedback, because you know, php and js). So I guess I would hate any other job in the field maybe likewise?
This job *is* convinient, salary, office
position, flexibility could not be better. At the end of the day it's not that stressfull. And i don't have any second of freetime (due to family) or energy i could offer a new and more demanding employer, can't work over time or even take a fulltime position, can't home office, can't earn less, can't travel very long to the office and especially can't go back to school to learn something completely new. Some of these constraints are softwe then other naturally but still my posibilities at the Moment are very limited. That might change in about five years if the family situation changed. So it would most likely be reasonable to stay until then at my current job? And bear being alone with this app, don't getting involved on any new project, don't learn anything new, don't invent anything.
There was one potential way out, they considered offering me PHD position to the upcoming ml part of the project... But I learned that I would attend to a bunch of classes at university first, which i would like to, but I don't think i have the time.
I feel trapped somehow. I also feel very lonely in the Office because those fucktards keep saying in home office.
Man, I don't want to go to work today.6 -
I gave a rant yesterday about this. But I have to say it again because it's so gratifying. It went like this
Me: "you should patch the module instead of using it for your python unit test."
Them: "You keep telling me this, but maybe there is a better way"
Me: "there is, I'm telling it to you"
Next day, Code review.
Me: "You need to change this"
... silent on the issue ...
On a call...
Me: "You need to patch the module. Don't mess up the namespace."
Them: "I don't think so, X did the work"
(In my head: then what did you do)
Me: "We can grab whoever you like Y, X. Let's see if X is busy"
... X isnt busy, hops on call 45 seconds later.
Me: "we're using the module, we should patch this'
X: Muses the thought for 2-3 seconds.
X: "yeah... Yeah we probably should patch that"
Moral of the story, don't take shit personally unless your right... Then relish in. But if your right and X says otherwise, you can always + a rant. -
I am very thankful to C as I face less pain while dealing with pointers and memory allocation and deallocation in C++. I am very thankful to C++, as I grasp OOP and template concepts out of it and it was also my first language for DSAlgo implementation. I feel very fortunate to move to Java after C++ rather than python. Although Java's design is f**ked and it feeds on a computer's memory, it taught me to deal with objects( unlike C++). It taught me how objects are clearly different than primitive data types like int, float, char...And best of all, Java provided me everything I need to safely switch to Python, it's all because of Java, I can clearly understand the working of python. All the stuff which I find weird in python before is sounding logical to me now. As java taught me how to deal with objects, I am confident to say that "I CAN DEAL WITH PYTHON". With respect to all my 3 prior languages: C, C++, and Java.2

honest question: if I know ReactJS, Golang, Python, Typescript, and a bit of Postgres and living in Costa Rica, what sort of freelance services could I promote on the net?
I used to freelance on sites like PeoplePerHour, doing projects of 1 month in 3 weeks or less, but I would like to do that again in my own website under my own terms, sort of speak.
any recommendations?2 -

OK, so, I see PY files shared on GitHub. All I know is, it is code for certain apps or pages. I download SEVERAL DIFFERENT PROGRAMS trying to get PY to open. Some didn't work, others were in Console and not Form. I asked for help on the Forum, how to open it, they do the same BS; gave me a Console app that just stays black for less than a second, and closes. I ask for a Form version. They made the excuse that it wasn't a program like I was thinking. They rudely tell me to be polite, but something like this IS GOING TO HAPPEN if they can't get their crap working. Eventually, after I TOLD THEM I WAS FURIOUS, THEY HIDE MY QUESTION FOR 10 MINUTES. When I replied, I DID NOT CUSS, I REPLACED LETTERS WITH ASTERISKS AND SYMBOLS, AND STILL GOT SUSPENDED, FOR A MONTH, AFTER TELLING THEM I WAS FURIOUS.
On the other hand, I was using Audacity. I upgraded and a plugin stops working. I thought they messed something up, so I wait using the outdated version for the fix for a few months, and so a few months later I update again, at this point I was a little upset; 2nd update and it still doesn't work. After the 3rd time, I thought they just didn't want to take the time and fix it, as people probably would have reported it by then. So I rant on Audacity's Forum saying they didn't fix an error, showed them screenshots in all versions I got and the 3 newest ones show an error. THEY TOLD ME WHAT WAS WRONG! I was trying to run a 32-Bit plugin on a 64-Bit version! I downloaded a 32-Bit version of the newest Audacity, and the plugin worked fine.
Python could've done what Audacity did, but, "No-o-o, we enjoy banning Winston when he is peed off!" And just so, the Suspension ends a day after my Birthday.
I might just ask when I'm back on, "How to remove my user off this Forum", so they can say "I can't", and flag it as malware because I almost no longer want they're help, and CAN'T GET AWAY FROM IT.
Freak you in the butt, Python.
PS - If anyone knows how to use Python files in Windows 10 or know a free, non-demo program that will more-advancedly edit, save, open PY files in a Form, please, give me the name or link to the software, program or app in the comments.
Before anyone says anything, this page says "Rant", so don't ban this or I'm deleting my account. If this isn't a "Rant" site, please tell me, and/or rename this site.
That is the reason I came here, just to get my frustration out.15
