I see this sentiment elsewhere in the thread, but my thinking upon reading the article was that these children are not just abandoning science research jobs by quitting science, but also relatively well-paying jobs in fields for which scien

My memory on the test itself may be a bit hazy (~24 years ago) and my interpretation at that age may not have been accurate, but I do seem to recall some amount of reasoning was required. E.g., looking at a graph and drawing a conclusion f

If education is anything like it was in my school years, I wonder if children are actively discouraged from pursuing science by educators that find the subject difficult or impractical to teach within their provided constraints. I have a ve

I've thought for a while that certain web technologies that Google is developing or promoting (e.g. WebGL, NaCl/PNaCl, V8, Chrome app store, Chromebook, etc.) has implied a vision of web apps being just as capable as desktop apps,

Doesn't surprise me that this was in Fremont, California at all. Out of curiosity, why? (I don't know much about Fremont, other than staying there occasionally when I can't find a closer hotel to my Silicon Valley customer

There's a good episode of Software Engineering Radio on this topic, as well: Episode 148: Software Archaeology with Dave Thomas http://www.se-radio.net/2009/11/episode-148-software-archaeo...

At least with IPv6 we won't have the mess of translation, requiring p2p apps to perform public address determination (and possibly port guessing). But you're right, the central problem remains.

I'm also anxiously awaiting the rise of IPv6, but I'm guessing that -- in a sane world -- consumer routers will still default to a stateful firewall for IPv6, thus necessitating the continued need for hole punching. :/

I just took a look at Linux's nf_conntrack_proto_udp.c to see what's happening. It looks like Linux starts the UDP timeout at 30 seconds, but extends it to 180 seconds when it sees traffic both ways, assuming it's "some

by simmons 12y ago
Also, the article frequently mentions a 120-second timeout interval, within which the connection needs to be refreshed. In Linux (and thus most consumer routers?), I believe the timeout is actually 30 seconds for UDP. :(

This a nice summary; I was actually thinking about doing my own writeup of this very thing. I have a few thoughts beyond what was covered in the blog post: For many protocols and modes of communication, UDP is really lousy for the develope

These are interesting problems, and we've certainly had a few debates at the Telehash meetups about the meaning of "identity" and such. Hashnames aren't expected to be human-friendly. Ultimately, I think it's a pr

by simmons 12y ago
Correct -- Telehash provides a basic communications layer, and is not an application, nor does it directly provide anonymity. The intention is to solve one specific problem, and solve it well. All sorts of applications could be built on t

* Software Engineering Radio. This podcast has great guests and isn't afraid to cover quite technical topics. Although, I think it has a bias towards enterprise software development, which isn't one of my major interests. http

For a while, I've been thinking about doing exactly this sort of analysis. Thanks for putting in the effort! Does anyone have experience getting a feed of the raw NWS forecast data for many points in a large region (e.g. a state or th

When I was a kid in the 80's, my parents once grounded me from my computers and radio. I wired a diode and earphone to the TV antenna lead in my room, and could listen to the town's radio station again. No resistor and complete

A blog post of mine was posted to HN a few years ago, and I thought, "where is all this traffic coming from?" I'm not sure how I missed HN before that.

Binder itself is very fast. I'm mostly thinking about the overhead of higher-level constructs build on top of binder (broadcast intents, etc.) that are handled in Dalvik code and that can become numerous as various apps make connectio

From my experience with working on Android internals, I also get the impression there is a ridiculous amount of IPC happening during normal operation, much of which involves Dalvik components (such as the activity manager) as intermediaries

It's in the extremely nascent stages right now. I think they'll be turning on the first residential gigabit customers in downtown shortly. We've occasionally discussed the idea of getting my condo complex in Arvada lit up -

It's quite possible that a judge might conclude that a warrant canary violates the spirit of a gag order. But I suppose there's only one way to find out.
