A thread on windows facts you actually don't know.

Two different types of windows operating system:
1. Windows -> Old windows that doesn't exist anymore.
2. Windows NT -> The version that is used nowadays in modern microsoft computers.

1/n

Originally, tweet length was 160 minus username length. One day, I turned to Jack and pointed out that I got one more character than him. He said, "That's not fair. We should standardize." I agreed. He said, "How about 140?" I said, "Sure." And he updated the code.

Last year, we upgraded tweet length to 280 and guess what? Use of 'please' is up 54% and 'thank you' is up 22%. I love that! Also, people are asking more questions and having more conversations. All this, and the majority of tweets are still under 140. It worked.

Torn between "I think losing $100 million when someone beats you at security research is pretty much exactly what you signed up for doing yield farming" and "Maaaaaaaybe not the future of finance you were expecting, huh."

How to put this in regular finance terms...

Suppose hypothetically you have an account at a brokerage with some valuable asset in it. You take a margin loan against that asset to fund your normal spending, or pay a tax bill, or maybe buy something at another brokerage.

For reasons known only to the brokerage, they don't denominate your loan in dollars. They denominate it in shares of a money market fund, which are worth $1 +/- epsilon and basically never deviate from that.

And you think "Hmm, I have a large equity cushion against this loan."

One day, a computer system at the brokerage reports, sorta-kinda erroneously, that the value of the money market fund is actually $1.30 per share. The equity cushion is gone. Your valuable asset is sold, at timing you didn't choose, at wrong price, to pay an inflated phantom debt

And your recourse is... probably tweeting at patio11 saying he finds too much joy in this.

Which I don't; I just feel like this is why you don't trust a CPU built out of redstone to build reliable financial infrastructure on top of.

🕵️‍♂️ How Google's PageRank algorithm works

The PageRank algorithm gives each page a rating of its
importance, which is a recursively defined measure of importance, based on if important pages link to it.
It's recursive because the importance of a page refers back to the importance of other pages that link to it

Here's how it works in practice:
1⃣ We start with some pages and crawl them for links

2⃣ Each page has 1/N points (where N as the total number of pages)

3⃣ Add points to each page for the amount of links to it, divided by the number
of links emanating from the sources of these links

The vast majority of images are jpegs, which are internally 420 YUV, but they get converted to 32 bit RGB for use in apps. Using native YUV formats would save half the memory and rendering bandwidth, speed loading, and provide a tiny quality improvement. It would also be \

a good path to supporting better video codec still image formats and 10 bit components. You can do it today, but you need to do the color conversion manually in a shader, which can be a big ask for some devs. Defining a FMT_JPEG_YUV that does driver injection akin to the \

external image support on Android could make it much more of a drop-in. Even doing it the hard way seems like it would be worthwhile for web browsers today.

A thread about Eastshade's bike mechanic!

When I originally thought of putting a bicycling in Eastshade, I was pretty sure it wasn't going to work, for the simple fact that if it was easy, we'd see a lot more rideable bikes in games. Well, I was wrong. It took a mere week.

Its essentially a first person controller with extra momentum, resulting in the the movement direction lagging behind your look direction. Then I used the angle between the look and the movement to dictate camera "bank" and handle bar rotation, and voila! Game changing feature!

The look of the bike was harder than the movement. Bicycles are fairly modern, so it was tricky to fit it to the setting. I took some artistic liberties and settled on a penny farthing (but wooden), ignoring how impossible that would be to ride on the rugged terrain in Eastshade.

Surprisingly, the hardest part was sound. It didn't feel like riding a bike until I found the right sounds and how to trigger them. For a while I was stuck thinking too realistically. A penny farthing is fixed gear, pedaling sounds nothing like a regular modern bike.

Finally I abandoned realism and went with sounds normal people would associate with biking. We're all so used to modern bikes that we strongly associate the distinct ticking of a freewheel mechanism (think of the sound when you stop pedaling and coast on a modern bike).
