They also thought, at the time, that they would "make money on the flow of money", without charging any fees (presumably by investing it and having some sort of fractional reserve scheme going on). That didn't pan out either and they found

Fun fact: Russ was the coder for a Chicago 'burbs-based demo group when he was about 17 (I met him at NAID 1996, when I was also 17. He later described PayPal to me as a method for transferring money with your Palm Pilot, like at a restaur

As an aside, there are currently 6221100 bitcoins in circulation (not counting ones that were lost, I suppose) and they are currently trading at around $7.50, which means Bitcoin has an implied market capitalization of around $46 million. N

AFAIK 433MHz can be used for any short-range application, similar to 27/49MHz for R/C cars. There are plenty off-the-shelf 433MHz transceivers for hobbyists, and I think car remote-unlockers use that band as well. And this doesn't appear

That sounds sorta like the neocortex algorithm stuff Numenta is working on, and has been working on for several years. I don't think they've achieved anything beyond what's possible with more conventional approaches yet.

I just found out about bitcoins last weekend, and ran the bitcoin miner, and then found out that it will take my 2.4GHz dual-core laptop 10 years to generate a bitcoin at the currently-established difficulty (without using my GPU, presumabl

I wish I could just buy blocks like these for my son. Bandai Spacewarp-type-things are a little too much yet, and the marble toys we have are pretty lame in comparison to this.

That's strange. In the latest Chrome, some of those soft hyphens fail to show up but it still splits the word, e.g. "abomina<br>tion". Other hyphenations appear just fine. Works fine in Safari.

It's funny that you say that, because you can buy an iPad-controlled quadrotor on Apple's store right here: http://store.apple.com/us/product/H1991ZM/A?fnode=MTY1NDA3NA...

I dunno, if you ever played a brass instrument, then you're playing on an (approximately?) just-tempered scale -- each valve combination is a harmonic series starting from the 2nd harmonic. Whether it's just-tempered over the entire scale

A coworker of mine was just bit badly by Java's insistence that unsigned types are so evil that the language shouldn't have them. He calculated a 32-bit hash, but since the ints are all signed, he took the absolute value before the modulo

Are these things really radiation-hardened enough to go into a "hot zone"? Won't that seriously mess with any semiconductors? Various manufacturers make radiation-hardened microcontrollers and so forth for going into space, but that's not

It probably had a modem that didn't pay Hayes to license the patent on enforcing a delay in switching from data mode to command mode (+++ did that, and then ATH0 was the AT command to hang up the phone -- normally you'd have to wait a coupl

via Wikipedia: The duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the cesium 133 atom. So I guess that means a meter is 30.66331898849836976219 cesi

My reddit karma shows 0, probably because it takes forever to load arbitrary /user/x pages on reddit until they're cached, at which point it merely takes a long time.

All of the Microsoft fonts have extremely good hinting, and still look great (well, legible) when shrunk down to tiny pixel sizes. It's the main reason I chose Trebuchet last time I needed a video game font. Though there were a lot of bet

Coincidentally, just today I implemented the greedy packed trie algorithm from Liang's thesis on LaTeX hyphenation [1]. The idea is to store the trie into a big array, overlapping the storage of your child nodes with one another where poss

Suggestion: ratings should be based on some kind of logistic model (like Elo ratings for chess) instead of the percentage of duels won. e.g., feed the scoring history into Bayeselo or something to get a ranking.

That's the only iPad app my 2-year-old needs help navigating. He likes to watch Thomas and Friends on it, but by the time he's asking for help he's added about 50 things to my DVD queue. This happens almost every day, so whenever I drop a
