Firefox Too Big To Link On 32-bit Windows 753

An anonymous reader writes "Firefox has gotten so large that it cannot be compiled with PGO on a 32-bit linker anymore, due to the virtual memory limitation of 3 GB. This problem had happened last year with 2 GB, which was worked around by adding a/3GB switch to the Windows build servers. Now the problem is back, and things aren't quite that simple anymore." This only affects the inbound branch, but from the looks of it new code is no longer being accepted until they can trim things from the build to make it work again. The long term solution is to build the 32-bit binaries on a 64-bit system.

Also, did they avert that? It seems like this is, in fact, the worst nuclear disaster since Chernobyl. Perhaps they averted it being the worst nuclear disaster ever, including Chernobyl, but it would have needed to be a lot less disastrous to not be the worst since. So...unless something worse than this but not as bad as Chernobyl comes along, I suspect we'll keep using it for this event for a long time...but there's a good chance the next disaster will be the "worst nuclear disaster since Fukushima" instead...at least, here's hoping....

huh??

The speed of light is constant across all frames of reference. Frames of reference that are moving relative to each other will perceive light generated by the other frame of reference as having a different "clock" (i.e., frequency), but the speed of the red/blue shifted light will be the same in both frames of reference. The speed of light itself does vary across mediums (say, water vs glass vs air vs vacuum), but that doesn't come into play here. Also, they weren't measuring, directly, the speed of the neutrinos. They were comparing the time of the neutrinos' arrival at different sites and they found a difference that was unexpected. However, that measurement depends very much on the clocks being in sync, and this is what TFA is discussing.

The bending of light in a refractive medium is completely unrelated to the bending in a gravitational field, and your conclusion that the latter involves the speed of the light being altered is false.

How does thermodynamics come into play? If the earth were a closed system, that would be one thing, but we have this convenient star that periodically gives us some extra energy....

As far as being "green" as pointed out elsewhere, this would, ideally, be "carbon neutral", although in practice it would at best be merely less carbon intensive than fossil fuels. So, it's "green" as in "not as bad as some alternatives".

What it really comes down to is using the biomass as a convenient storage and transport mechanism for solar energy. In the end, that's what we want to use, one way or another, for pretty much every energy technology except nuclear fission/fusion. The trick is just finding the way to use solar energy which maximizes convenience and minimizes the bad side-effects.

I think a more interesting solution for gassification would involve picking the fuel source for maximum efficiency...off the top of my head, it'd be very interesting to see what sort of efficiency could be gotten if they grew algae, say, and created dehydrated pellets from it to use as fuel. Perhaps someone has tried that?

IBM Building 120PB Cluster Out of 200,000 Hard Disks 290

MrSeb writes "Smashing all known records by some margin, IBM Research Almaden, California, has developed hardware and software technologies that will allow it to strap together 200,000 hard drives to create a single storage cluster of 120 petabytes — 120 million gigabytes. The data repository, which currently has no name, is being developed for an unnamed customer, but with a capacity of 120PB, it's most likely use will be a storage device for a governmental (or Facebook) supercomputer. With IBM's GPFS (General Parallel File System), over 30,000 files can be created per second — and with massive parallelism, and no doubt thanks to the 200,000 individual drives in the array, single files can be read or written at several terabytes per second."
