You know who sucks at developing APIs?
Facebook.
I mean, how are so high paid guys with so great ideas manage to come up with apis THAT shitty?
Let's have a look. They took MVC and invented flux. It was so complicated that there were so many overhyped articles that stated "Flux is just X", "Flux is just Y", and exactly when Redux comes to the stage, flux is forgotten. Nobody uses it anymore.
They took declarative cursors and created Relay, but again, Apollo GraphQL comes and relay just goes away. When i tried just to get started with relay, it seemed so complicated that i just closed the tab. I mean, i get the idea, it's simple yet brilliant, but the api...
Immutable.js. Shitload of fuck. Explain WHY should i mess with shit like getIn(path: Iterable<string | number>): any and class List<T> { push(value: T): this }? Clojurescript offers Om, the React wrapper that works about three times faster! How is it even possible? Clojure's immutable data structures! They're even opensourced as standalone library, Mori js, and api is great! Just use it! Why reinvent the wheel?
It seems like when i just need to develop a simple react app, i should configure webpack (huge fuckload of work by itself) to get hot reload, modern es and jsx to work, then add redux, redux-saga, redux-thunk, react-redux and immutable.js, and if i just want my simple component to communicate with state, i need to define a component, a container, fucking mapStateToProps and mapDispatchToProps, and that's all just for "hello world" to pop out. And make sure you didn't forget to type that this.handler = this.handler.bind(this) for every handler function. Or use ev closure fucked up hack that requires just a bit more webpack tweaks. We haven't even started to communicate to the server! Fuck!
I bet there is savage ass overengineer sitting there at facebook, and he of course knows everything about how good api should look, and he also has huge ass ego and he just allowed to ban everything that he doesn't like. And he just bans everything with good simple api because it "isn't flexible enough".
"React is heavier than preact because we offer isomorphic multiple rendering targets", oh, how hard want i to slap your face, you fuckface. You know what i offered your mom and she agreed?
They even created create-react-app, but state management is still up to you. And react-boierplate is just too complicated.
When i need web app, i type "lein new re-frame", then "lein dev", and boom, live reload server started. No config. Every action is just (dispatch) away, works from any component. State subscription? (subscribe). Isolated side-effects? (reg-fx). Organize files as you want. File size? Around 30k, maybe 60 if you use some clojure libs.
If you don't care about massive market support, just use hyperapp. It's way simpler.
Dear developers, PLEASE, don't forget about api. Take it serious, it's very important. You may even design api first, and only then implement the actual logic. That's even better.
And facebook, sincerelly,
Fuck you.17 -
"So I have this awesome app idea..."
Proceeds to tell me, "I'll be, like, the face of the company, and you can just focus on the tech stuff, in the background."
Chad called me ugly nerd, so I took his idea, got an investment from his own father, built the company, and sold it.
See Chad got a new job as a sales development rep
At the company I built and sold
Haha epic2 -
# Retrospective as Backend engineer
Once upon a time, I was rejected by a startup who tries to snag me from another company that I was working with.
They are looking for Senior / Supervisor level backend engineer and my profile looks like a fit for them.
So they contacted me, arranged a technical test, system design test, and interview with their lead backend engineer who also happens to be co-founder of the startup.
## The Interview
As usual, they asked me what are my contribution to previous workplace.
I answered them with achievements that I think are the best for each company that I worked with, and how to technologically achieve them.
One of it includes designing and implementing a `CQRS+ES` system in the backend.
With complete capability of what I `brag` as `Time Machine` through replaying event.
## The Rejection
And of course I was rejected by the startup, maybe specifically by the co-founder. As I asked around on the reason of rejection from an insider.
They insisted I am a guy who overengineer thing that are not needed, by doing `CQRS+ES`, and only suitable for RND, non-production stuffs.
Nobody needs that kind of `Time Machine`.
## Ironically
After switching jobs (to another company), becoming fullstack developer, learning about react and redux.
I can reflect back on this past experience and say this:
The same company that says `CQRS+ES` is an over engineering, also uses `React+Redux`.
Never did they realize the concept behind `React+Redux` is very similar to `CQRS+ES`.
- Separation of concern
- CQRS: `Command` is separated from `Query`
- Redux: Side effect / `Action` in `Thunk` separated from the presentation
- Managing State of Application
- ES: Through sequence of `Event` produced by `Command`
- Redux: Through action data produced / dispatched by `Action`
- Replayability
- ES: Through replaying `Event` into the `Applier`
- Redux: Through replay `Action` which trigger dispatch to `Reducer`
---
The same company that says `CQRS` is an over engineering also uses `ElasticSearch+MySQL`.
Never did they realize they are separating `WRITE` database into `MySQL` as their `Single Source Of Truth`, and `READ` database into `ElasticSearch` is also inline with `CQRS` principle.
## Value as Backend Engineer
It's a sad days as Backend Engineer these days. At least in the country I live in.
Seems like being a backend engineer is often under-appreciated.
Company (or people) seems to think of backend engineer is the guy who ONLY makes `CRUD` API endpoint to database.
- I've heard from Fullstack engineer who comes from React background complains about Backend engineers have it easy by only doing CRUD without having to worry about application.
- The same guy fails when given task in Backend to make a simple round-robin ticketing system.
- I've seen company who only hires Fullstack engineer with strong Frontend experience, fails to have basic understanding of how SQL Transaction and Connection Pool works.
- I've seen company Fullstack engineer relies on ORM to do super complex query instead of writing proper SQL, and prefer to translate SQL into ORM query language.
- I've seen company Fullstack engineer with strong React background brags about Uncle Bob clean code but fail to know on how to do basic dependency injection.
- I've heard company who made webapp criticize my way of handling `session` through http secure cookie. Saying it's a bad practice and better to use local storage. Despite my argument of `secure` in the cookie and ability to control cookie via backend.18 -
I think something's wrong with me... I just went on StackOverflow and answered questions for roughly 4 hours and it was a blast1

Feeling the need to know everything about web dev (frontend for now) already yesterday, though not having a clue, what to look at first, as it's its own universe. Everything has a million ways of implementation, combination and features worth looking at.
Already have worked with basic HTML, CSS and JS, had a short look a Typescript, being confronted with React Typescript + Redux + thunk, SASS, learned some basics of all.
Feeling lack of motivation to build smth to learn, yet I want to explore. Afraid to get stuck in tutorial hell, although I know, changing smth here and there in the projects is a must for learning. Feeling the lack of understanding the bits and pieces of what can be styled with CSS in which way. Understanding how npm, webpack, the strange parts of JS, ES6, work.
So ... freaking ... much ....2 -
I like react, I really do. But one thing I hate about it, is the number of decisions I need to make, I get so fucking confused whether to use redux thunk or sagaas, inline styles or styles components, redux or flux, even to judicially choose whether to use a state management library or not. It just lack of my own experience or don't know what. But this thing sucks2

Finally done implementing this fuck shit API...
As pr my last rant, I had to implement an API that prints a document twice using "Microsoft Print to PDF"... Turns out that's a shit task, who would have thunk 😑
This is one big ass Calvinball game and I'm not a fan, but if that's the shit you have to do, then I guess I'll try to make it resilient... -
Orchid lesson #many:
Church tuples exist only to demonstrate how general substitution is. Just like Church numerals, they aren't meant to be used for real computation and cause a lot of problems. Few type systems and fewer optimizers can deal with them, they're a pain to pass through FFI boundaries, and they're much slower in an interpreted context than a native smart array. And in a lazy language the tuple is almost always lighter than the code that generates it, so you want to generate the tuple eagerly and thunk the actual elements, if thunk you must.
I'll go write a vector based tuple and end this madness tomorrow. New version soon, probably.
With dynamic dispatch.7 -
Anyone using Redux Thunk with a router? Can I cancel a promise on location change like in Redux Saga? Occasional setState warning appeared to me and it's annoying
