>webdevs don't count when it comes to programming

I never got this meme..

WebDev is so much harder than the average John Doe JavaDev job..

Maybe you don't need to be able to explain B-Trees in detail or write a Lexer/Parser. But unless we are talking HTML-bb tier there's a metric shitton to know:

HTML5, responsive Webdesign, CSS3, SASS/SCSS, JavaScript, maybe CoffeeScript/Typescript/Dart.. those are the fucking bascis.

Now we start making a real website, so I know you know your MongoDB, SQL.. what are database normalizations again?

Stuff like JQuery, Bootstrap, Normalize, Grunt Gulp, Bower, Webpack, Jasmine and so on are mandatory, but if you want a real Job you better know your Angular, React (including Flux, Redux).

Things like JSON, XML, YAML are not even worth mentioning, you know them like the back of your hand.


So you want a Job with those?
WTF!! That's only the Frontend we were talking about..

So fuck off unless you know your Node.JS and maybe something like Django (including Python) or Rails (including Ruby) and - why not - a littel bit of PHP (maybe 1 or 2 frameworks) might come in handy.


Congratiulations, you are a WebDev 101 without any special skills.

If you want some respect you better know your HTTP requests, maybe a littel bit of graphic design (if you work design). You should also be able to implement a socket, what was BigEndian vs. LittleEndian again?

OK, and of course a Framework is not a monolithic thing, so say you programmin Ruby, you don't know Rails alon, but also Sinatra. And of course as much of the ecosystem as you can, so example for Rails you need at the very least a decent grasp of RVM, Bundler, Rake, Rackup, RSpec, CanCanCan, HAML.. and everything keeps mogin, i.e. in Rails 5 you have to learn ApplicationRecord instead of ActiveRecord.

Furthermore we didn't even touched DevOps, deployment or Servers. You know your nginx, apache, passenger, thin, puma, unicorn..?


WebDev sooo easy...

WebDev is "hard" because webdevs MAKE it hard for themselves. You stupid faggots have no less than 12 different """frameworks""" for javascript JUST for the aesthetic development of a website, and that's JUST for your client-facing parts. Oh and that's JUST for javascript, too. Only now are webshits starting to realize the absolute mess they're in because they've got 40 different frameworks for the same two or three languages.

If you listen to any kind of podcast/e-radio show that interviews different people in the industry and you reach an episode about a web developer, it'll be a non-stop waterfall of buzzwords and frameworks. Programming Throwdown had their latest episode be about scaling websites and they had the most insufferable-sounding prick as their guest who would just rattle off framework memes to sound intelligent.

>>57159592

>>57159509
I haven't written anything to generate .obj files in a long time, but I always thought the numbers represented vertices defined earlier or later. For instance, you would define some points and connect them to form a square:

v 0.000000 0.000000 2.000000
v 0.000000 0.000000 0.000000
v 2.000000 0.000000 0.000000
v 2.000000 0.000000 2.000000
f -4 -3 -2 -1

I'm not sure this works going forward in a program, as I have never tested it, but I'd be surprised if it worked differently.

I've never seen the second style you provided.

>>57159662
The opcode without a parameter makes most of the instructions completely useless.

There are assembly ISAs where the op ode can fit within one byte or even smaller (ie 6 bits) but no one calls them bytecodes.

x86 has instructions that can be one byte thanks to the variable lengtb abolity yet no one calls it a bytecode

No, it's not that simple.

All those frameworks exist to solve different problems. Some day some WebDev programmed something the 703rd time and thought to himself "there has to be a better way to do this!".

But when you just look at something like Two-way bindings for the first time you won't understand what they are usefull for, or why you do it like this and not like that.

And it's not even about the aesthetics, you want secure, maintainable, scalable, ... websites.


Look at it like this:
Computers are much older than the internet. So while the programming langauges had almost a century to get mature, WebDevelloping is not that old.

And jsut when they thought they figured it out (i.e. 960 grid), something happend (i.e. smartphones) that made everything before completely irrelevant. A lot of mistakes were made, a lot of lessons learned.

Everything is moving very fast, but it's not because webdev are MAKING it hard, its because there is still a lot of work to do.

Maybe the last few years the WebDevellopment has reached some point of maturity, but there's more topics to come in the future..

I am trying to learn MATLAB and SIMULINK. I just bought it last night and have been playing around with it. It seems powerful, and somehow it can generate C code. I haven't figured that out yet. Can't wait to take some advanced math, eng., or physics classes so I can start using this already.

Python, C, C++, and Ruby are on the back burner. Some day I will learn how to use Swift...

>>57160718

My point is, if HTML is a turing machine, then pebbles are also a turing machine, because you can lay then on the ground and have a binary storage.

99% of what you listed is cross disciplinary / common sense. if you can understand a lexer / parser (eg recursive tree logic) then of COURSE you know XML/json.

If you took a basic OS course then you certainly understand interprocess communication better than a web dev (and why the fuck would a webdev be fucking with sockets anyway??).

If you took a basic ASM class of course you know little/big endian better than a web dev.

If you took a language theory class you can easily pick up the nuances of all the meme scripting languages webdevs use.

If you took an intro to software engineering course you can pick up any flavor of the day framework, provided it follows MVC design standards

Furthermore, since very few modern apps DONT involve multiple hosts communicating, you could argue everyone is webdev now. consider the IoT and how even embedded systems dudes have to know transport logic these days.

No. Maybe and JSON are close to each other, but for the most technologies it's not.

The point it, complexity is not within a certain task, but complexity arises as emergence from the complex system that a website can be.

>If you took a basic OS course

Why would a ASM guy know/care if IP adresses are made big endian or little endian?

That's actually correct. SICP made me better in Ruby and JS.


>If you took an intro to software engineering course you can pick up any flavor of the day framework, provided it follows MVC design standards

Oh, the Irony. WebDevs brought MVC on a whole new level. Look at the details of Angular or Ember and notice the sublte differences between MVVM, MVC and so on..

BSP trees.

It's been over 10 years since I've last touched them in any way. Then I suddenly remember their existence and realize that a BSP tree is exactly what I need: just draw a bunch of static polygons in perfect back-to-front order, no matter where the camera is.

This is just a simple test scene. No depth testing needed to render it. Going to need a bigger scenes for testing, but so far everything looks good.

Okay /dpt/, this is going to sound a bit weird...
My girlfriend (18) is senior year in high school and lives with her parents. She wanted me to turn her XBOX 360 controller into a vibrator with the vibration motor since she can't get one (parents). I have some knowledge of C# and XNA so I wrote this:

//intensity is an int
KeyboardState keystate = Keyboard.GetState();            
            if(keystate.IsKeyDown(Keys.Down) && intensity > 5)
                intensity -= 5;
            if(keystate.IsKeyDown(Keys.Up) && intensity < 9990)
                intensity += 5;
            if(keystate.IsKeyDown(Keys.Space)) {
                GamePad.SetVibration(PlayerIndex.One, 0f, 0f);
                Exit();
            }
            float preciseIntensity = intensity;
            preciseIntensity /= 1000;
            GamePad.SetVibration(PlayerIndex.One, preciseIntensity, preciseIntensity);

The SetVibration function takes floats so that's what I initially used, but for some reason I could go over 1.0f which the controller can't do. Then I tried ints since I've heard float comparison is a bitch, but it would still go higher than 1.0f. How do I prevent my gf's pussy from being destroyed by her XBOX 360 controller?

    intensity += 5;
if(keystate.IsKeyDown(Keys.Space)) {
    GamePad.SetVibration(PlayerIndex.One, 0f, 0f);

}

Seriously reevaluate your life choices.

Additionally, if you can write that code like that and think that a valid solution to your current problem of having SetVibration to not exceed 1.0f is to switch fundamental numerical data types rather than checking and capping the value before passing it to SetVibration, you should kill yourself.

>Easier to write
Depends on what you're writing. I haven't found better alternatives. There's always tradeoffs.
>easier to finish projects with
Like what? What kind of project do you actually finish faster?
Because in my view you finish different amounts of work. If you want you can write a video player from scratch using opengl and OS interfaces in C. But that's a very different task from writing a gui for a video library and calling it your player. C can do that too. That you're using C doesn't necessarily mean that you're working at a much lower level from other languages (depending on the language) and often its not harder.
>More jobs
I'm no job market expert (unlike you I'm sure) but I find that there's very high demand for C developers. When you're talking about other more popular languages (funny way of putting it given C is still a rather massive share of the job market) there's often a much higher level of aptitude within that market required to actually get hired.

>Why not learn something else
Why not learn C? It's one of the most persistent languages around, one of the few performance oriented languages if you look at the most popular languages available in a time where our performance headroom is quickly shrinking.
It's a small and rather easy language to learn. It has a compiler on every platform I know of. I don't think it will ever really go away. And most infrastructure (energy, waste, water etc.) relies on the older languages. Where C is one of the primary languages. If more and more people focus on the popular languages all the time (as they are) you're gonna find that the average salary for C programmers (or fortran, cobol etc) will rise. And its already quite high. Especially for people who specialise with C programming (being an expert at good API, optimising for specific hardware etc).

This answer is far longer than you deserve (I do this for free). But I find it important to not be mislead early on.

Anon just a heads up, you should just go buy her an actual vibrator/toy.

Sticking a 360 controller up your vagina is incredibly unsanitary, and is also difficult to get fully clean.
There's a much greater chance of her getting an infection, which would be pretty bad for both of you.

>>57161650

It's not a big problem at all. You select an epsilon to use with your comparison that's appropriate for the resolution available.
More explicitly:

 
if(myValue>0-epsilon&&myValue<0+epsilon)
     //do thing 

This produces an approximate 'range' where we can consider myValue to be equal to 0.
In your case

But either way. Your issue is not a float comparison issue. I'm not sure what your float version is but I recommend clamping rather than trying to detect if you're at the max or not. That is to say see if the value is over 1. If it is you set it to 1. Same with zero (if it's less than 0 set it to 0).

But she really should do this shit herself.

That's what morons do. Unless you're writing in high level languages but this is too trivial to assume that still.

>>57161800
Convinced on what. No one persuaded her. She just wants to try something new.

>>57161808
She can't do it herself. This makes a lot of sense though. Thanks!

>>57161826
I'm not saying that the computer is wrong. I'm just saying that the way it stores floats makes them hard to compare.

That's exactly the problem

algebra is so difficult to implement in 3d

I just can't visualize this stuff

>>57161785
buy her a cheap phone (those with buttons)

>>57161888
I don't get it...

>>57161899
Why when she already has a vibrating device at home?

>>57161907
so that it doesn't look suspect, so that she doesn't insert belly shit in her hole and because you don't know other way to solve the problem.

How high of a COM port is normally assigned for USB devices? I'm making a program scanning and flashing USB devices and I'm just testing every COM port to see if there is a valid device on there, but how high do I need to check? Can I encounter like COM10 ports normally? What about COM20 or higher?

>Has two phones
Yeah they wont think she's masturbating. They'll think she's dealing weed.

>>57161943
>insert belly shit
What are you talking about? Also not inserting.

>mfw we're still talking about controller masturbation

Come on, chaps. It was entertaining at first, but back to the topic.

>>57162022
What topic?

>>57161996
>belly shit
The same stuff you have in your belly is in your keyboard. And the ammount is bigger than what is found in your anus.

Anon just include the xbox controller next time you have sex. Or ignore all the comments here.

Church-encoded higher inductive types in cubical type theory. Well, that was easy. It's also nice because cubical type theory becomes parametric type theory when abstracted a bit, meaning you can derive induction and not just recursion.

Circle : U
Circle : (A : U) => (a : A) => Path (i -> A) a a => A

base : Circle
base A a p = a

loop : Path (i -> Circle) base base
(loop @ i) A a p = p @ i

I think you mean he should include himself next time she fucks the xbox controller.
Doesn't go well when the cuck challenges the bull. And this bull offers her more than sexual pleasure. He's screwed.

Kill yourself.

>>57162079
Heterogeneous equality that isn't a mere proposition, i.e. two terms of the same path type are not necessary equal. Integral to homotopy type theory.

>>57162097
ok now explain it better

Bump? I thought you were the best of computer academia here at /dpt/. With all your fancy functional languages and fizzerbuzzin.

Under the Curry-Howard correspondence, a term of the type

Path (i -> A) a a'

is a proof that a = a' given that their types are also equal.

 a(()=>b(()=>c(()=>{})));

anti idempotent

>>57162173
what does i -> A do

>>57162190
It's to do with the cubical type theory part, but it's how you witness that the types are equal. If the dimension i is in the context, a type A is a line, a proof that the endpoints (the types of a and a' respectively) are equal.
