I was rather hoping this would be a hawking radiation method, i.e. actually generating light using gravity


You and I both. This isn't even carbon neutral. I mean technically this is burning carbon molecules.


burning carbon molecules sourced from photosynthesis. Carbon positive, but the fuel generation is carbon negative, so it balances out.


This is more of a sales pitching device (and it's a nice one) than a useful tool


Looks really good, can't quite tell if it can interleave lines from several sources if not this would be an excellent feature.


Yes, log messages from different files are interleaved based on their timestamps.


Any facility for piping, for example to route an adb logcat (live remote log tail from android) through it?

Of course, I could redirect the adb logcat output to a file and point this at that, but it'd be nice to have the sugar to not have to explicitly wrap the process.


You can pipe into lnav like you can with less/more:

  make |& lnav
The '-t' option will prepend timestamps to the lines that are coming in on stdin so that it will be treated as a log file. The '-w <file>' option will write the stdin data to a file if you want to look at it later:

  make |& lnav -t -w /tmp/make.out
Is that what you're asking about?


Sure is. Sounds great!


I think this might be a daft question, but why can't they inject packets with a (roughly) appropriate TTL for the current sequence that they're hijacking? From the two examples shown one might think they're picking ttl's more randomly


They could make the packets stand out less, but there'd still be the overlapping reply from the legitimate Baidu host, unless the attackers went full MITM.

In case anyone is confused: we're now talking about the TTL of the packets coming from hijackers, whereas I was originally talking about the TTL of the packets going towards Baidu and the hijackers. The TTL the hijackers send won't affect the tracing method I was suggesting.


in figure 7, Faradays Law: changing magnetic field in the left torus induces a variable current in the wire, then via ampere's law the changing current in the wire induces a magnetic field in the second torus.

However in figure 8 while there is an A field which extends to infinity, don't forget that B = curl(A) and so the magnetic field of the torus is going to be confined within it. As such there's no way to induce a new field in the additional torus. A is a potential, it's not a "real" field in as much as you can only measure things like |B| and |E| (or quantum phases induced by A in the Ahranovov-Bohm experiment)


Thank you. That was a nice, concise answer! (it's been a while since I've had any E/M)


In which area of interest? As for journal access, i suggest using public computers in a university library. Not tremendously practical but they're always subscribed.

It appears you likely have neighbors working nearby. How do they feel about the Grados?


Yet another article about the parity breaking at rhic, i work in this field and while this would be very exciting it's not a cut and dry result. Running the numbers for the proposed theoretical cause of the parity violation leads to something a lot smaller than what is observed. While making simpler, non parity violating, arguments based on geometry and the elliptic flow in the fireball can get you near the right numbers.

See this paper for another explanation of the observed charge correlations http://arxiv.org/abs/1002.1758

downloaded the linux version, nice music and it seems like it mostly takes place through bbs conversations which is great but its a shame you cant type the messages, just click.

Fantastic music


don't forget the yang-mills mass gap and the navier-stokes initial value problem, both clay millennium problems and both rather important. Well the yang-mills one is probably more important, this list is a bit m-theory biased.

I think the m is originally for membrane, not "magic" but apparently its open to interpretation.


The way those problems are posed, by the Clay Institute, they're more math problems than physics problems. Check out the price lectures on their site to see what I mean.
