Well put. The Open Philanthropy folks take a broadly similar view of the probabilities, both of when strong AI is likely to arrive and of how much positive influence per dollar they can have on how things turn out: http://www.ope

In case anybody is wondering how to roll out server-side support for this with a fallback to GIF: they've added "image/apng" to the Accept header for image requests. It's now "image/webp,image/apng,im

What? According to the article, "44 percent of the 'top-selling smartphones' in the US had activated FM radios". If you want a mainstream smartphone that can listen to FM radio, that is totally a thing you can just buy.

A bit of googling doesn't turn up any mention of that sort of sketchy business. This seems like a pretty standard, innocuous publicity/recruiting event. The world already has enough scandals without inventing fictional ones.

If you want to guarantee that this will never happen, RE2 and similar regular expression engines are guaranteed to run in O(n) time, where n is the length of the target string. https://swtch.com/~rsc/regexp/ I&#x2

If you use the naive algorithm at the top of the page but iterate over UTF-8 code points rather than bytes -- which is straightforward, BTW -- you will get some cleverness automatically in the compiler's implementation of the switch

It's also possible to chunk the index array: to store the byte-index of every 16th rune, say, and do a bit of cheap iteration afterward. I've had good success with this approach: it's fast, it's light on memory, and it p

I agree that you never said otherwise, and I applaud you for your accuracy in not doing so. :-D The reason I bring it up is that UTF-16 is a very commonly used internal encoding for strings, and regular expression engines for platforms whic

by pjscott 10y ago
Backtracking in a UTF-8 string is easy: when you need to remember a location, just record its byte offset. You have exactly the same issue in UTF-16, which is also variable-width and therefore not O(1)-indexable by code point. There are loa

Looks like those slides are for an older version. Since then they've bumped up the size of the vector execution units from 64 bits to 1024 bits and quadrupled the number of them, if I'm reading this right. http://www.an

Sure! They have a neural net that they pre-trained for image recognition as a demo. They ran it on the mobile device both times -- no cloud involved -- but the one on the left is running on the CPU, while the one on the right is running on

Everybody at my school took one of those. It was all platitudes all the time. No substance at all. Every once in a while I hear someone call for more people to have to sit in Platitude Class, and I can't figure out why.

Whoa, that's some practical syntax. Suddenly I'm filled with envy that none of the C-family languages have that.

You should be able to replace the pow(2, x) part with (1 << x), so e.g. getbit() becomes return (bits[n/8] & (1 << (n%8))) >> n%8; The compiler will turn the division and modulo into shifting and masking.

See also bitfields, which make the compiler generate the shifting and masking code for you: https://en.wikipedia.org/wiki/Bit_field

If they'll be launching thousands of satellites, I expect the marginal cost of replacing one launch to be lower than what most satellite makers could manage. And then, reliability has a cost of its own. Have you calculated the optimum?

This conversation badly needs concrete examples. "Workers rights" sounds like a nice thing -- but what, exactly, does it mean? What specific policies are we talking about? For example, you can have an interesting argument about mi

To be clear, that's a quote from Donald Trump -- not Peter Thiel.

That's some pretty advanced selective reading. From the same paragraph: "I don’t think any class of people should be disenfranchised."
