Wow, isn’t there a really low probability of finding your phone number in the first 200m digits of pi? (0.09995% in first 100m) I’m tempted to start throwing a dictionary of phone numbers through this pi lookup to find your number, call you, and verify, I think you could quickly narrow in on your phone number given the information above.

I think you'll have trouble. Assuming the first digit of the phone number is somewhere between 114.5 million and 115.5 million, you have 1 million potential 11 digit numbers to check. There are 10^11 sequences with 11 digits. The number of people in the USA is 3×10^8, and we can assume there is roughly 1 number per person (some people don't have a phone number and some people have more than one, but it turns out that…

It'd be a great 1 person-audience magic trick to call up all 3000 of those people and say, "Hi sjcsjc, I found your phone number in Pi".

http://www.angio.net/pi/ My 11 digit phone number occurs around the 115 millionth digit, a grand saving of two digits.

Also depends on the length of the metal rod, doesn't it?

The observable universe is 2^205.5 Planck lengths across, so you can store at most 205 bits, or 25 bytes.

And at that length your latency gets reeeeeeal bad.

Your snake game doesn't even have food for the snake to eat? The snake just grows without eating, until the head collides with the tail somewhere? Pssh, amateur hour... /s (Just kidding this is actually super cool.)

My first thought was to make random sectors of the first hard drive the "food"... For better or for worse, this stuff really brings me back to my teens. Nice job!

You just reminded me of an old game that made "snow" for the screen by copying a specific location on the disk into video memory.

Further irony: this page weighs over 30MBs , thanks to a huge GIF that is arguably not necessary for the article.

Yeah, not happy about that idiocy (probably 1MB as video) burning through 10% of my monthly bandwidth on the first day of the month...

You just made me think of a GIF-to-mp4 conversion service that runs as a proxy.

Sadly, because of the "HTTPS everywhere!!!11" thing, such a service would not be viable (it would need to rewrite the to a in order to work, of course).

Same. I come here to witness what is basically programming magic to me. I'll need a couple of life times before I can become this skilled.

You can do “magic” with relatively easy things. For example, spend a weekend with https://forthsalon.appspot.com or processing.org and see where you can get to...

Awww. That first link silently requires WebGL in order for the animations to work, and doesn't implement a fallback. :'(

Opera were offering something like this for a while. With the support of a browser and HTTP proxying it's not a problem, the SSL terminates at the proxy and is re-encrypted under the proxy's SSL.

Many web services will take an uploaded gif and turn it to webm before showing it, e.g. Twitter.

Linux vs BSD (ie Mac OS X). Sorry about that. Also, you shouldn’t paste weird looking things from the internet in your console :P

yeah paste it into your plain text editor first and then do a code review and then save it to a jump drive and spin up the old backup computer that’s been wiped clean and then open up a sandboxed vm and then remove the wifi chip and then run it

If it was March last year, you wouldn't have wanted to run anything marked "only works in Edge", particularly if you were using Win10 on VMWare - https://arstechnica.com/information-technology/2017/03/hack-...

There’s a comment on the page. For some reason, emulators (at least the ones I tried) wait 4x what real machines wait when you use BIOS int 15b 86h. You can tweak the code if you want to play at a faster speed. There’s probably a sound explanation for this discrepancy...

I can't say I entirely understand how the Elapsed Time Wait works, but testing in qemu, I was able to get it to a good speed by replacing the inc cl with a nop inc dx By opening in a hex editor, finding bf86 fec1 and replacing with bf86 9042 If you're on a very slow system, maybe just use 2 nops or a 2-byte nop.

I couldn't find "bf86 fec1". I did however find "b486 fec1".

"bf86 9042" made it literally so fast I physically couldn't keep up. The following worked for me (w/ QEMU on old (no KVM) Pentium M), this may be too fast on newer machines:

  xxd cd.iso | sed 's/89c3 01de b486 fec1 cd15 b445/89c3 01de b486 9042 cd15 b445/' | xxd -r > cd2.iso
(Note the creation of "> cd2.iso")
