William Byrd's work in program synthesis is an interesting take on this, where an IDE can, guided by test cases written for a function, actually auto-complete code itself whilst writing the function, or tell the programmer when they ha

The chromeos security model praised in this article seems quite too conservative for devs to me, considering the inconvenience trade-offs: - persistent state is discouraged, but not disallowed. in fact, when the browser is exploited, any&#x

I'm an erlang fan but I wouldn't claim message passing is "fast" in the sense that you might be thinking of (though copying data does have some GC and CPU cache performance benefits that are harder to reason about.) Ther

For one, we've lost these services to capitalism, because it's difficult for any alternative to operate in a capitalistic society. How many are going to work on the open source alternative and still make enough to live comfortably

Yes, it's crucial for our safety for the FCC to hold the power to shutter any website -- Wheeler knows humanity and the interwebs too well -- because we have all had that moment: venturing too many clicks deep, we stumbled upon a geoci

ah so they weren't even asked to ID content in a smarter way, like YouTube does? if their goal was really to enable piracy, did they think pirates would really give up without finding out that they could simply insert random bytes to e

MEGA could have made byte-identical content de-dupable yet still unreadable to MEGA.. which would save storage space but might still retain the whack-a-mole quality: if your upload gets taken down, you may simply change any one byte in the

This is an oversimplification, though I don't doubt that there is a lot of infrastucture crud especially in large companies, which is a problem that /should/ be fixed. But to measure utilization without any context is naive:
