Why browsers are bloated

Let's reinvent the fucking scrollbar, which every goddamn platform with a UI already has, and make it behave subtly different from the native one!

Right-click a native scrollbar in some other app:
- Scroll Here
- Top
- Bottom
- Page Up
- Page Down
- Scroll Up
- Scroll Down

Right-click a scrollbar in Chrome:
- Back
- Forward
- Reload
- Save As...
...

Right-click a scrollbar in Firefox and Opera:
Absolutely fucking nothing happens!

What the fuck!? How did these terminally retarded idiots get involved in creating one of the most important pieces of software to the average user?

Make it dependently typed, y'all. Embrace the future now. Ain't no dependently typed browser engines out there yet, right?

"dependently typed"? We don't need any of that academic wank abstract bullshite. All that'll do is introduce bloat.

Actually, dependent types help reduce bloat. For instance, runtime array bounds checks become obsolete, which can lead to 10-20% of performance improvement.

Most of these are used by shitty programmers. You don't need them.

Define a container that can hold several types of elements.
Define a fold function that works on several types of containers.
Can C do that without C "macros"?

Like struct (and maybe with a enum "tag" and a union if you want to save space) or a void *.

Define a fold function that works on several types of containers.

Surely there are more examples.

Yes as you can see.

int fn(void *, void *)
No automatic dispatch on the type of the container. Also, type-unsafe shit. Might as well use Lisp instead.

>>259
Also:
if (fn(&bp[i * size], arg) == 0)
bp[i * size]
This implies that the container is indexable and, what's worse, contigious. How are you going to fold/map a tree then? C is useless.

You can easily modify it to work with any data structure.

Actually, even C++ has std::accumulate which is a generic fold. And C++ is hardcore, painful Sado-Masochistic programming just like you love. So C is a useless archaism even among the imperative posse. You should retire and watch Santa Barbara, gramps, not read the internet.

You'd have to write a map function for trees (as you would for C++). Fold can be done using the visitor pattern.

Name: Anonymous 2014-11-16 19:38

>>271
So it would be a separate function specifically for trees? C is useless.

Pass another function pointer as argument that each time it is called it will show the next element to be folded.

Name: Anonymous 2014-11-16 22:16

>>272
It's also a separate function in C++. They just look the same when you call it.

Name: Cudder !MhMRSATORI 2014-11-17 12:49

>>258-277
Traversing an array and calling a function on each element is something like ~5 bytes for the main loop:
array_fold_loop:
lodsd
call ebx
loop array_fold_loop

Calling a function is already 5 bytes, and then you still have to setup the parameters for it, so it's smaller and faster to just write the loop directly.

Traversing a binary tree (pre-order, nodes stored as [data, left, right]) is a bit less than 32 bytes, so it does make some sense to have this be a separate function if you're going to use it more than once:
tree_fold:
lodsd
call ebx
lodsd
test eax, eax
jz no_left
push esi
mov esi, eax
call tree_fold
pop esi
no_left:
lodsd
test eax, eax
jnz has_right
ret
has_right:
mov esi, eax
jmp tree_fold

But the tree structures I'm using for DOM/rendering can be traversed non-recursively, see http://bbs.progrider.org/prog/read/1406427616

>>269
All that looks like it's doing is essentially caching the results of rendering each subtree, which is not anything interesting.

One thing that I don’t yet understand though, is how this plays out with memory usage.
Oblivious dumbfuck... this is why software is so fucking bloated!

I want to say fold(container) and have it work, no matter what type "container" is or the type of its elements is. That's fucking generics, if you didn't know: being able to define generic functions, functions that work on general stuff, not just on specific types.

>>277
If the call is the same, then that's one generic function with lots of instances. It's the same in Common Lisp, Haskell and any decent language. But if you have to waste your time on shit like fold_rbtree_double (as in C), then that's not generic, it's useless.

>>278

Programmers don't give a shit about "bytes", "bits", "cycles" or any of that sewer infrastructure that has the honor of running programs. Because wasting time on floor-scrubbery means having less time to actually write useful programs.
