Its that time of the morning again where I get nothing done and moan about the past ... thats right its practiseSafeHex's most incompetent co-worker!!!
Today I'd like to tell you the story of "i". Interesting about "I" is that he was actually a colleague of yesterdays nominee "G" (and was present at the "java interface" video call, and agreed with G!): https://devrant.com/rants/1152317/...
"I" was the spearhead of a project to end all projects in that company. It was suppose to be a cross-platform thing but ended up only working for iOS. It was actually quite similar to this: https://jasonette.com/ (so similar i'm convinced G / I were part of this but I can't find their github ID's in it).
To briefly explain the above + what they built ... this is the worst piece of shit you can imagine ... and thats a pretty strong statement looking back at the rest of this series so far!
"I" thought this would solve all of our problems of having to build similar-ish apps for multiple customers by letting us re-use more code / UI across apps. His main solution, was every developers favourite part of writing code. I mean how often do you sit back and say:
"God damn I wish more of this development revolved around passing strings back and forth. Screw autocomplete, enums and typed classes / variables, I want more code / variables inside strings in this library!"
Yes thats right, the main part of this bullshittery was putting your entire app, into JSON, into a string and downloading it over http ... what could possibly go wrong!
Some of my issues were:
- Everything was a string, meaning we had no autocomplete. Every type and property had to be remembered and spelled perfectly.
- Everything was a string so we had no way to cmd + click / ctrl + click something to see somethings definition.
- Everything was a string so any business logic methods had to be remembered, all possible overloaded versions, no hints at param types no nothing.
- There was no specific tooling for any of this, it was literally open up xcode, create a json file and start writing strings.
- We couldn't use any of the native UI builders ... cause strings!
- We couldn't use any of the native UI layout constructs and we had to use these god awful custom layout managers, with a weird CSS feel to them.
What angered me a lot was their insistence that "You can download a new app over http and it will update instantly" ... except you can't because you can't download new business logic only UI. So its a new app, but must do 100% exactly the same thing as before.
His other achievements include:
- Deciding he didn't like apple's viewController and navigationBar classes and built his own, which was great when iOS 7 was released (changed the UI to allow drawing under the status bar) and we had no access to any of apples new code or methods, meaning everything had to be re-built from scratch.
- On my first week, my manager noticed he fucked up the login error handling on the app I was taking over. He noticed this as I was about to leave for the evening. I stayed so we could call him (he was in an earlier timezone). Rather than deal with his fucked up, he convinced the manager it would be a "great learning experience" for me to do it ... and stay in late ... while he goes home early.
- He once argued with me in front of the CEO, that his frankenstein cross-platform stuff was the right choice and that my way of using apples storyboards (and well thought out code) wasn't appropriate. So I challenged him to prove it, we got 2 clients who needed similar apps, we each did it our own way. He went 8 man weeks over, I came in 2 days under and his got slated in the app store for poor performance / issues. #result.
But rather than let it die he practically sucked off the CEO to let him improve the cross platform tooling instead.
... in that office you couldn't swing a cat without hitting a retard.
Having had to spend a lot more time working with him and more closely than most of the other nominees, at a minimum "I" is on the top of my list for needing a good punch in the face. Not for being an idiot (which he is), not for ruining so much (which he did), but for just being such an arrogant bastard about it all, despite constant failure.
Will "I" make it to most incompetent? Theres some pretty stiff competition so far
Tune in later for more practiceSafeHex's most incompetent co-worker!!!6 -
Okay, story time.
Back during 2016, I decided to do a little experiment to test the viability of multithreading in a JavaScript server stack, and I'm not talking about the Node.js way of queuing I/O on background threads, or about WebWorkers that box and convert your arguments to JSON and back during a simple call across two JS contexts.
I'm talking about JavaScript code running concurrently on all cores. I'm talking about replacing the god-awful single-threaded event loop of ECMAScript – the biggest bottleneck in software history – with an honest-to-god, lock-free thread-pool scheduler that executes JS code in parallel, on all cores.
I'm talking about concurrent access to shared mutable state – a big, rightfully-hated mess when done badly – in JavaScript.
This rant is about the many mistakes I made at the time, specifically the biggest – but not the first – of which: publishing some preliminary results very early on.
Every time I showed my work to a JavaScript developer, I'd get negative feedback. Like, unjustified hatred and immediate denial, or outright rejection of the entire concept. Some were even adamantly trying to discourage me from this project.
So I posted a sarcastic question to the Software Engineering Stack Exchange, which was originally worded differently to reflect my frustration, but was later edited by mods to be more serious.
You can see the responses for yourself here: https://goo.gl/poHKpK
Most of the serious answers were along the lines of "multithreading is hard". The top voted response started with this statement: "1) Multithreading is extremely hard, and unfortunately the way you've presented this idea so far implies you're severely underestimating how hard it is."
While I'll admit that my presentation was initially lacking, I later made an entire page to explain the synchronisation mechanism in place, and you can read more about it here, if you're interested:
http://nexusjs.com/architecture/
But what really shocked me was that I had never understood the mindset that all the naysayers adopted until I read that response.
Because the bottom-line of that entire response is an argument: an argument against change.
The average JavaScript developer doesn't want a multithreaded server platform for JavaScript because it means a change of the status quo.
And this is exactly why I started this project. I wanted a highly performant JavaScript platform for servers that's more suitable for real-time applications like transcoding, video streaming, and machine learning.
Nexus does not and will not hold your hand. It will not repeat Node's mistakes and give you nice ways to shoot yourself in the foot later, like `process.on('uncaughtException', ...)` for a catch-all global error handling solution.
No, an uncaught exception will be dealt with like any other self-respecting language: by not ignoring the problem and pretending it doesn't exist. If you write bad code, your program will crash, and you can't rectify a bug in your code by ignoring its presence entirely and using duct tape to scrape something together.
Back on the topic of multithreading, though. Multithreading is known to be hard, that's true. But how do you deal with a difficult solution? You simplify it and break it down, not just disregard it completely; because multithreading has its great advantages, too.
Like, how about we talk performance?
How about distributed algorithms that don't waste 40% of their computing power on agent communication and pointless overhead (like the serialisation/deserialisation of messages across the execution boundary for every single call)?
How about vertical scaling without forking the entire address space (and thus multiplying your application's memory consumption by the number of cores you wish to use)?
How about utilising logical CPUs to the fullest extent, and allowing them to execute JavaScript? Something that isn't even possible with the current model implemented by Node?
Some will say that the performance gains aren't worth the risk. That the possibility of race conditions and deadlocks aren't worth it.
That's the point of cooperative multithreading. It is a way to smartly work around these issues.
If you use promises, they will execute in parallel, to the best of the scheduler's abilities, and if you chain them then they will run consecutively as planned according to their dependency graph.
If your code doesn't access global variables or shared closure variables, or your promises only deal with their provided inputs without side-effects, then no contention will *ever* occur.
If you only read and never modify globals, no contention will ever occur.
Are you seeing the same trend I'm seeing?
Good JavaScript programming practices miraculously coincide with the best practices of thread-safety.
When someone says we shouldn't use multithreading because it's hard, do you know what I like to say to that?
"To multithread, you need a pair."18 -
Somebody asked on how to get started on Full Stack web application development.
This is how I got started.
Client side Web Application Development:
---------------------------------------------------------------
• Start with basic HTML, CSS and JS, JSON. For quick learning, see W3Schools for these topic or YouTube it.
• Get a local web server. "200 OK!" webserver chrome extension is a good start. (https://chrome.google.com/webstore/...)
• Learn Chrome Dev Tools to debug the pages. YouTube it.
• Get a good IDE. I am very happy with VSCode. You can use it for very serious WebApps.
• Start learning JavaScript language in depth, but just related to Web Browser related topic or you would get sucked in server side too early.
• Install node.js. Learn NPM package manager. Learn basic node commands.
• Learn complexity of JS file referencing, JS modules in browser. Just learn, don't use it yet, to understand the benefits of code bundlers.
• Learn Webpack code bundler.
• Learn how to make you simple site much faster and using in Mobile using "Progressive Web Apps".
• Now learn to make modular UIs. I love React. Focus on getting the UI code modulear. Create Single Page sites. (You are not there yet to create a Web App) “Create-React-App” started kit is a good starting point.
• Learn to create multi-page site using React-router.
• Learn application state management using Redux.
• Learn to create application decision engine using Redux-Saga.
Practice and master each stage.
Along above, learn git / GitHub (to learn from others code), find good web resources like Medium / Smashing magazine, good YouTube channels etc. I subscribed to some popular Udemy courses too.
Server side Web development:
------------------------------------------
:) First learn client side Web Application development. Server side learning is another story.3 -
When I got to learn about json yesterday I hate it cause I need to do extra work to MVC project. But after today the instructor told us what it does, and I love it. Gonna start learning this stuff more tomorrow1

"So Alecx, how did you solve the issues with the data provided to you by hr for <X> application?"
Said the VP of my institution in charge of my department.
"It was complex sir, I could not figure out much of the general ideas of the data schema since it came from a bunch of people not trained in I.T (HR) and as such I had to do some experiments in the data to find the relationships with the data, this brought about 4 different relations in the data, the program determined them for me based on the most common type of data, the model deemed it a "user", from that I just extracted the information that I needed, and generated the tables through Golang's gorm"
VP nodding and listening intently...."how did you make those relationships?" me "I started a simple pattern recognition module through supervised mach..." VP: Machine learning, that sounds like A.I
Me: "Yes sir, it was, but the problem was fairly easy for the schema to determ.." VP: A.I, at our institution, back in my day it was a dream to have such technology, you are the director of web tech, what is it to you to know of this?"
Me: "I just like to experiment with new stuff, it was the easiest rout to determine these things, I just felt that i should use it if I can"
VP: "This is amazing, I'll go by your office later"
Dude speaks wonders of me. The idea was simple, read through the CSV that was provided to me, have the parsing done in a notebook, make it determine the relationships in the data and spout out a bunch of JSON that I could use. Hook it up to a simple gorm golang script and generate the tables for that. Much simpler than the bullshit that we have in php. I used this to create a new database since the previous application had issues. The app will still have a php frontend and backend, but now I don't leave the parsing of the data to php, which quite frankly, php sucks for imho. The Python codebase will then create the json files through the predictive modeling (98% accuaracy) and then the go program will populate the db for me.
There are also some node scripts that help test the data since the data is json.
All in all a good day of work. The VP seems scared since he knows no one on this side of town knows about this kind of tech. Me? I am just happy I get to experiment. Y'all should have seen his face when I showed him a rather large app written in Clojure, the man just went 0.0 when he saw Lisp code.
I think I scare him.12 -
How could I only name one favorite dev tool? There are a *lot* I could not live without anymore.
# httpie
I have to talk to external API a lot and curl is painful to use. HTTPie is super human friendly and helps bootstrapping or testing calls to unknown endpoints.
https://httpie.org/
# jq
grep|sed|awk for for json documents. So powerful, so handy. I have to google the specific syntax a lot, but when you have it working, it works like a charm.
https://stedolan.github.io/jq/
# ag-silversearcher
Finding strings in projects has never been easier. It's fast, it has meaningful defaults (no results from vendors and .git directories) and powerful options.
https://github.com/ggreer/...
# git
Lifesaver. Nough said.
And tweak your command line to show the current branch and git to have tab-completion.
# Jetbrains flavored IDE
No matter if the flavor is phpstorm, intellij, webstorm or pycharm, these IDE are really worth their money and have saved me so much time and keystrokes, it's totally awesome. It also has an amazing plugin ecosystem, I adore the symfony and vim-idea plugin.
# vim
Strong learning curve, it really pays off in the end and I still consider myself novice user.
# vimium
Chrome plugin to browse the web with vi keybindings.
https://github.com/philc/vimium
# bash completion
Enable it. Tab-increase your productivity.
# Docker / docker-compose
Even if you aren't pushing docker images to production, having a dockerfile re-creating the live server is such an ease to setup and bootstrapping the development process has been a joy in the process. Virtual machines are slow and take away lot of space. If you can, use alpine-based images as a starting point, reuse the offical one on dockerhub for common applications, and keep them simple.
# ...
I will post this now and then regret not naming all the tools I didn't mention. -
Yay! I got my head wrapped around Vue3 parent / child components and fed the whole thing JSON data loaded via Axios. A small feat perhaps, but it just feels great to still "get" stuff when learning becomes harder as I get older.4
-
Fuck NodeJS. I don't want you to be asynchronous sometimes. My gahwd I need like 3 deep nested loops just to get you to make a request and compile a damn JSON of requests.
I'm learning Golang goodbye forever node.15 -
Was working on a game and I hated having to hardcode stuff I wanted to add so I started splitting it into external json files but by the end (and to an extent still learning it) learnt how to do mod support and simple user generated content, really cool stuff to learn about.
-
Having a vodka and coke and trying to learn how to use a JSON api on a android app (also learning that). I'm sure it will go well.2

The real life of me as a trainee developer:
New system works locally but fails to work in production and dev.
Proceeds at futile attempts to debug for hours to find out that my connection strings in the transforms were nested inside logging. -
I have been working on IoT projects for last five years. After using MQTT in many of my projects I have realized that there is a huge learning curve for the beginners to understand and implement MQTT in their projects. The packet structure of MQTT is complex and MQTT packets are difficult to debug. Also customizing the open source MQTT brokers are also difficult for the beginners, and sometimes even for the experts.
To make IoT and Messaging simple, I am designing a new protocol which uses JSON packets for data exchange and is far less complex than MQTT. I am also developing an open source project which will contain a server (with load balancer support), a python client, a Javascript client and a python based load balancer. I hope this project will reduce the development time as the protocol is easy to understand and the open source code is fully modular & easy to customize.
This will be my very first contribution to the open source community. Wish me luck! -
Aspiring freelance/junior web dev here, I'm familiar with WSGI (using Flask), some PHP, Apache, JSON, and Vanilla JS. What other technologies should I be learning to make myself more marketable?6

v0.0005a (alpha)
- class support added to lua thanks to yonaba.
- rkUIs class created
- new panel class
- added drawing code for panel
- fixed bug where some sides of the UI's border were failing to drawing (line rendering quark)
v0.0014a (alpha) 11.30.2023 (~2 hours)
- successfully retrieving basic data from save folder, load text into lua from files
- added 'props' property to Entity class
- added a props table to control what gets serialized and what doesn't
- added a save() base method for instances (has to be overridden to be useful beyond the basics)
- moved the lume.serialize() call into the :save() method on the base entity class itself
- serialized and successfully saved an entities property table.
- fixed deserializion bugs involving wrong indexes (savedata[1] not savedata[2])
- moved deserialization from temp code, into line loading loop itself (assuming each item is on one line)
- deser'd test data, and init()'d new player Entity using the freshly-loaded data, and displayed the entity sprite
All in all not a bad session. Understanding filing handling and how to interact with the directory system was the biggest hurdle I was worried about for building my tools.
Next steps will be defining some basic UI elements (with overridable draw code), and then loading and initializing the UI from lua or json.
New projects can be set as subfolders folders in appdata, using 'Setidentity("appname/projectname") to keep things clean.
I'm not even dreading writing basic syntax highlighting!
Idea is to dogfood the whole process. UI is in-engine rendered just like you might see with godot, unity, or gamemaker, that way I have maximum flexibility to style it the way I want. I'm familiar enough with constructing from polygons, on top of stenciling, on top of nine-slicing, on top of existing tweening and special effects, that I can achieve exactly what I want.
Idea is to build a really well managed asset pipeline. Stencyl, as 'crappy' as it appeared, and 'for education' was a master class in how to do things the correct way, it was just horribly bloated while doing it.
Logical tilesets that you import, can rearrange through drag-n-drop, assign custom tile shapes to, physics materials, collisions groups, name, add tag data to, all in one editor? Yes please.
Every other 2D editor is basic-bitch, has you importing images, and at most generates different scales and does the slicing for you.
Code editor? Everything behavior was in a component, with custom fields. All your code goes into a list of events, which you can toggle on and off with a proper toggle button, so you can explicitly experiment, instead of commenting shit out (yes git is better, but we're talking solo amateurs here, they're not gonna be using git out the gate unless they already know what they're doing).
Components all have an image assignable to identify them, along with a description field, and they're arranged in a 2d grid for easy browsing, copying, modifying.
The physics shape editor, the animation editor, the map editor, all of it was so bare bones and yet had things others didn't.
I want that, except without the historic ties to flash, without the overhead of java, and with sexier fucking in-engine rendering of the UI and support for modding and in-engine custom tools.
Not really doing it for anyone except myself, and doubt I'll get very far, but since I dropped looking for easy solutions, I've just been powering through all the areas I don't understand and doing the work.
I rediscovered my love of programming after 3-4 years of learning to hate it, and things are looking up.2 -

So I thought to myself.
Hey I'll go ahead and use python, it will make this easier than using c++.
So I start looking at python.
And I start looking at specific common functions that c/c++ and .net all offer.
Like writing a fucking png image.
And I start seeing 3rd party libs that are at version 0.2
And so I say, this is supposedly the language data people love. which would include searching gis data too right ?
Everybody touts this level for ai and machine learning and all this other bullshit but I can't even create a fucking image ? And every document points to this same lib where it comes to creating this image ? at version 0.2 ?? 20 years or more after PNG was created ?
So I look up geotiff, and see 0.4........ so..... what is this language good for again ? I can parse json in javascript and do the other things I want...
Oh scatterplot generation ? What is it being displayed in jpeg ? Maybe the jpeg implementation is good. because you know i just use scatterplots constantly. yup. most of the data I require to analyze uses scatterplots. not risk.
fun.
oh and look django.... who the fuck uses django ?
and omg it makes me format my text or the run bombs.....
jesus. rpg much ?
I'm just... I'm not seeing...
WHY ?????????
and then I have zimmermans voice buzzing in my head about just using goddamn .net26 -
Hello council of elders.. or should I say "console"? Heh? Heh? I've been up for a long time sorry.
Anyway. I've started learning framework stuff. Angular right now. Been long overdue tbh. And I found a free course on udemy and followed it. It's cool and everything but I gotta ask...
Why can't I just use vanilla js and everything from scratch? I'm not sure if its the course I'm using (I'd appreciate more resources. Thanks) but I feel like it's a lot of effort. Is there something I'm missing or haven't learned yet?
It might sound stupid please let me know why it's better to use that than regular methods. Apparently it's meant to make stuff easier but I feel like it's just a lot linking files and making various things in different places.
Also. Other stupid question which might just be cause of the course but like... Is it mostly just for manipulating json??
Thanks. More questions to come soon!!3 -
Any SUPER AWESOME patient... JS PRO that wants to help me with a few problems it would be appreciated..
Okay so I'm having trouble with JavaScript and this can apply to other languages but for now focus on JS. so I'm learning how to manipulate the DOM and I don't really know how to start I picked out a tutorial but I'm afraid I wont learn a lot from it. here are my concerns and yes they don't all have to do with the DOM
> I don't know how to learn without mimicking what the person is doing and when I try something that's related I cant use the related information and techniques because I either don't remember, dont want to do the literal same thing for something slightly different or dont know how and somethings not working even though it should be.
> I do it one way and when people offer to help its just me getting responses of how it could be done completely different and I dont understand why either way should be used
> Why should I have to generate a webpage or div if I can just use HTML5
>whats the difference between JSON and Arrays???????????
>I am not good with arrays, lists, dictionaries, (I'm stretching to python with lists and dictionaries)
>I recently tried the basic quiz project and it was more complicated and fun than I was giving credit for but I want to do it a different way to show myself I learned but I cant because I dont understand how the person managed to loop through the entire array printing the individual questions and answers to the div. like I understand the parts that use the html tags in the code but I dont know how when or what to use it all
>any good javascript/dom resources?
At this point Im just stressing because all I want is a basic skillset with JS but I dont feel like Im learning anything and I dont know how to apply my knowledge or improve upon the programs ive been learning from or trying to make. and arrays have been tripping me up to especially since I have no clue what the difference is between them and JSON and why I should use one over the other and dont get me started how shit I am with manipulating them. FUCK IM STUPID10 -
So, I started fiddling around APIs which returned data in JSON and parse that data in PHP and it feels so good.... Past 3 days I've been in deep learning PHP and practically $this is the best thing....
I need recommendations for such APIs, so far I've used
1. Chuck Norris Jokes (http://api.icndb.com/jokes/random/)
2. User's IP Address and details (http://ip-api.com/php/)
What would you recommend, let me know..1 -
Work has set us a challenge to build a rock/paper/scissors/dynamite/waterbomb api. We have the spec for what json is expected incoming and outgoing. We are allowed to implement any way we want and with any language we want. We are considering using Clojure but we have no experience with it, hence we will hopefully be learning as we go. Would you recommend using a framework like Pedestal, Hoplon, Luminus, or just use Leiningren or something else?
-
I had to start over learning SQL when I faced the JSON functions of PostgreSQL during a try and error period to get nested json_agg in one query.. I'am too old for that low level stuff! 🤨
-
Started learning/using graphQL for my personal project and it’s really interesting! It solves my major concern of huge json response5
-
I'm browsing through my old 'learning projects'.
I realized that I didn't knew json and exploded the whole json string and had an array with 4 dimensions.
