I'M BACK TO MY WEBDEV ADVENTURES GUYS! IT TOOK ME LIKE 4 MONTHS TO STOP BEING SO FUCKING DEPRESSED SO I CAN ACTUALLY STAND TO WORK ON IT AGAIN
I learned that the linear gradient looks cool as FUCK. Honestly not too fond of the colors I have right now, but I just wanted to have something there cause I can change it later. The page has evolved a bunch from my original concept.
My original concept was the bar in the middle just being a URL bar and having links on the sides. If I had kept that, it would have taken me a few hours to get done. But as time went on when I was working on it, my idea kept changing. Added the weather (had a forecast for a while but the code was gross and I never looked at the next days anyways, so I got rid of it and kept the current data). I wanted to attempt an RSS reader, but yesterday I was about to start writing the JavaScript to parse the feeds, then decided "nah", ended up making the space into a todo list.
The URL bar changed into a full command bar (writing the functions for the commands now, also used to config smaller things, such as the user@hostname part, maybe colors, weather data for city and API key, etc)....also it can open URLs and subreddits (that part works flawlessly). The bar uses a regex to detect if it's a legit URL (even added shit so I don't need http:// or https://), and if it's not, just search using duckduckgo (maybe I'll add a config option there too for search engines).
At this very moment it doesn't even take a second to fully load. It fetches weather data from openweathermap, parses it, and displays it, then displays the "user" name grabbing a localstorage value.
I'm considering adding a sidebar with links (configurable obviously, I want everything to be dynamic, so someone else could use my page if they wanted), but I'm not too sure about it.
It's not on git yet because I was waiting until I get some shit finished today before I commit. From the picture, I want to know if anyone has any suggestions for it. Also note that I am NOT a designer. I can't design for shit.12 -
I fucking hate chained methods. Ok, not all of them. Query things like array.where.first... that stuff is ok.
Specially if it's part of the std lib of a lang, which would be probably written by a very competent coder and under scrutiny.
But if you're not that person, chances are you'll produce VASTLY inferior code.
I'm talking about things like:
expect(n).to.be(x).and.not(y)
And the reason I don't like it is because it's all fine and dandy at first.
But once you get to the corner cases, jesus christ, prepare to read some docpages.
You end up reading their entire fucking docs (which are suboptimal sometimes) trying to figure if this fucking dsl can do what you need.
Then you give up and ask in a github issue. And the dev first condescends you and then tells you that the beautiful eden of code he created doesn't let you do what you want.
The corner cases usually involve nesting or some very specific condition, albeit reasonable.
This kind of design is usually present in testing or validation js libraries. And I hate all of those for it.
If you want a modern js testing lib that doesn't suck ass, check avajs. It's as simple as testing should be.
No magic globals, no chaining, zero config. Fuck globals forced by libs.
But my favorite thing about it that is I can put a breakpoint wherever the fuck I want and the debugger stops right fucking there.
Code is basically lines of statements, that's it, and by overusing chaining, by encouraging the grouping of dozens of statements into one, you are preventing me from controlling these statements on MY code.
As an end dev, I only expect complexity increases to come from the problems themselves rather than from needlessly "beautified" apis.
When people create their own shitty dsl, an image comes to my mind of an incoherent rambling man that likes poetry a lot and creates his own martial art, which looks pretty but will get your ass kicked against the most basic styles of fighting.
I fucking hate esoteric code.
Even if I had to execute a list of functions, I'd rather send them in an array instead of being able to chain them because:
a) tree shaking would spare from all the functions i didn't import
b) that's what fucking arrays are for, to contain several things.
This bad style of coding is a result of how low the barrier to code in higher level langs are.
As a language or library gets easier to use you might think that's a positive thing. But at the same time it breeds laziness.
Js has such a low learning curve that it attacts the wrong kind of devs, the lazy, the uninspired, the medium.com reader, the "i just care about my paycheck" ones.
Someone might think that by bashing bad js devs I'm trying to elevate myself.
That'd be extremely stupid. That's like beating a retarded blind man in a game and then saying "look, I'm way better than this retarded blind man".
I'm not on a risky point of view, just take a stroll down npmjs.com. That place is a landfill. Not really npm's fault, in fact their search algorithm is good.
It's just the community.
Every lang has a ratio of competence. Of competent to incompetent devs.
You have the lang devs and most intelligent lib devs at the top. At the bottom you have the bottom.
Well js has a horrible ratio. I wouldn't be shocked to find out that most js devs still consider using import or await the future.
You could say that js improved a lot, that it was way worse beforr. But I hate chaining now, and i hated back then!
On top of this, you have these blog web companies, sucking the "js tutorial" business tit dry, pumping out the most obscenely unprofessional and bar lowering tutorials you can imagine, further capping the average intelligence of most js devs.
And abusing SEO while they're at it, littering the entire web with copy paste content.2 -
try{
someObject.someAttribute = (int?) reader["columnName"];
}catch{
someObject.someAttribute = null;
}
Or, same coworker, another piece of code:
if(((int?)reader["foo"]).HasValue){
bar = (int?)reader["foo"];
}else{
bar = null;

I want to do one project in which using arduino uno and RFID reader to take attendance but for this I have to need 100 reader card which is costly. So I thought using bar code so I can print barcode on paper and no need any card. So does anyone idea where I can get bar code module for arduino uno.4
