:fa_youtube_play: Cool Computing Videos

Notch tweeted about the following video and I found it really interesting (I knew I followed him for a reason):
https://www.youtube.com/watch?v=ZsRRCnque2E
It's about the internals of the C64, and explains some of the tricks people used to get the most out of the hardware. I'm sure this won't interest everyone, but there are bound to be a few similarly weird people here.
If you know of any other interesting videos of a similar nature, feel free to post them below.
-
I lived the C-64, baby.

Well, there's this one:

There's this about the original Elite. One of the original developers talks about quite a few different things relating to the development of the game. I found the rendering part especially interesting - it gives an insight to what kind of things they had to do to get it running at all.
Worth listening to if you have the 57 minutes to spare.

That was pretty good. I definitely found the technical aspects more interesting than the history. I find it hard to imagine having to develop with such tight constraints, but it makes the final product seem much more impressive.
-
Just watched this, pretty interesting

Not available in my country.

Perhaps that's the problem, I live in one of the few remaining civilised countries in the world. For now, anyway. We're doing our best to change that.
-
WTF? I'm in a shithole, and they let me watch it.
It seems to work for me (in the UK). I haven't got time to watch it yet though, so I'll probably check it out on the weekend.

A must watch for anyone working with javascript

That's Misko Hevery, one of the authors of angular.js. Made before they published angular officially, but probably while they were already working on it. Interesting. Watching it.

Oh so you like old computers' internals? Well it doesn't get any better than this:

I agree - that's a hard one to beat.

Ok, watched the polymorphism video. Pretty typical OO best practices stuff from the mid to late 2000-s. They still haven't decided composition > inheritance and the whole functional programming love affair was just starting out.
But for what it is, it's not bad. I might watch the rest of the series.

Hah! I love the heroic intro music. More programming videos should start that way. I might browse through it.

I like one of the YouTube comments: "This won't get a segfault!"

On the other hand, out-of-bounds values could have pretty dire consequences...

This is getting kind of off topic but speaking of mechanical videos, this one is great:

Are there people who didn't know how differentials worked? Wasn't that in middle school science?
I have to admit, though, I didn't know you could do math on them. I can't imagine how precisely they had to machine those gears so that 2 revolutions wouldn't get the whole thing out-of-sync...
-

differentials are easy to explain how they work.
Limited slip differentials (which are far better for things like getting out of mud as they won't let one wheel stay stationary and one wheel spin like crazy) are a lot harder to explain how they work!
-
Nah that was like a plot point in My Cousin Vinny.
Which is where everybody gets their information about automobile engineering.
-
refresh my memory then, because i watched that on black friday and i seem to recall that the plot point was that the two differentials functioned differently but didn't go into the physics of why they functioned differently.

Limited slip is fucking magic.

Welcome to my life! :starts crying:

The CVT in my hybrid that combines three power sources (1 engine, 2 electric motors) into a single output shaft, when any one of the three could be idling, is fucking magic to me.
It's amazing to think that there are people who can dream shit like that up.
-

True, but it appears they have planned for that. The spiral cams have a "non-computing run-out" at both ends — and presumably some sort of out-of-bounds indicator for the operator. The racks might be more of a problem, but presumably they are also longer than necessary for the valid range, as well as having an out-of-bounds indicator. The rotating parts won't be damaged by rotating too far, of course, but I have no idea how they handle overflow/underflow.

That's nothing. Because musical scales are logarithmic in nature, it's possible to use two banjos placed side-by-side as a slide rule.

Best. Use. For. Banjos. Ever.

It probably uses concentric planetary gearsets. They are pretty cool.
-
That's not too hard. Not entirely dissimilar to the internal working of a Conventional automatic, actually.
The CVTness isn't actually integral to the combining multiple inputs part. If space weren't a concern you could just as easily do the same on a conventional automatic. You can also do the same with a conventional manual, but nobody does because they aren't maximally efficient and having a human in the gear ratio loop expands the complexity of the computing problems involved dramatically.
In other words, manuals are out due to cost and economy numbers. Conventional automatics are out for packaging and weight reasons.
-
For some reason, I haven't watched this one before.
Once you get over the goofy premise, it's pretty funny and interesting. I'm not sure I agree with his vision, but I'm nowhere nearly enough qualified to argue.

As rhetorical devices go, it irritates me like fury. Why do people have to do that sort of thing? A simple tripartite story, with beginning, middle and end, is quite enough for a talk.

Google is supposed to be the king of the web, but all their language/framework stuff is meh. It had to be fucking Facebook to truly impress me with their thinking on React and Flux.

hmmm the internet disappoints me.
i wasn't able to find what i wanted with a couple of GIS requests, but i did find this which is strangely relevant.

Who paints their fingernails green?

- someone who wants ten mini greenscreens on their hands when they do their hand model stint
or - someone about to a line or two of facebook (apparently)

GREEN?!
YOU CALL THAT GREEN?!That's turquoise.

Here's a full list of colours for you as you seem to be making colours up. These can appear in various shades:
RED
ORANGE
YELLOW
GREEN
BLUE
PURPLE
BROWN
BLACK
WHITE
GR[AE]Y (technically light black)
PINK (technically light red)That's nine colours, plus two pseudo-colours.
In light of this, those fingernails are definitely painted GREEN.
-
Græy as a shade of black doesn't make any sense! Are you confusing shades with tints?
Or perhaps you meant dark white?
Also, I'm pretty sure brown is a shade of orange.
-

Maybe.
Or perhaps you meant dark white?
I'll accept that both græy and black can be considered dark white, or that græy and white can be considered light black, but I feel that the three names are common enough to be included as distinct colours.
Also, I'm pretty sure brown is a shade of orange.
As above.

I'm with @aliceif on this one; those nails are definitely turquoise. Or jade. One of those two.

They look more like

It occurs to me that, as part of our technical requirements, we should probably know the words "cyan" and "magenta" too. Although they're synonyms for GREENBLUE and PINK.
-
Magenta is REDPURPLE

Now I'm confused, are you supporting the scale where we have thousands of colour names, or where we have only 6 or so?
