  1. Re:The More Important Discovery on Cause of Aurora Borealis Confirmed · · Score: 1

    Actually I kind this kind of interesting, the explanation I had always heard was that a wave of charged particles boiled off of a sunspot and that it was electrical charge of that wavefront collapsing some field lines and streaming down the magnetic holes at the poles. Knowing that there is actually a continuous event from the sun to the earth is an interesting realization for me.

    Actually I was thinking why not use carbon-carbon for the leading edges, the SR-71 was apparently speed limited by the max temp of 427C for the inlet to the compressor whereas carbon-carbon composites can withstand 3000C+.

    You wouldn't burn alive while falling from 100K feet, Joe Kittinger Junior jumped for 102,800 feet and just got a bit warm. Of course if you didn't have a pressurized suite and supplemental air you'd be screwed.

    Supercruise on the F-22 is said to be in the Mach 1.5-1.6 range which is amazing since many previous generation jets barely made it there with afterburners. Add in the stealthiness and maneuverability and it's one slick plane.

    The L model Core2Duo processors max at 17W so I guess if you have it and a mobile GPU maxed you would draw about 30W. That's still not enough to cook your lap =)

    Do you have a P4 based laptop or something, or are you running Linux with no power management and doing compiles? Most of my laptops draw 45W peak and the majority of that is for the LCD backlight, the CPU doesn't draw enough power to heat much of anything.

    Hmm, 24V*50A=1200W/120V=10A, even most older knob and tube wiring can handle that (barely).

    although it's really not related to XP at all.

    Not true at all, the code for XP x64 SP2 and 2003 x64 SP2 is mostly common with the obvious addition of the server related stuff to the 2003 version, but they were built off the same codebase.

  9. Cordless contractor equipment on Toshiba To Launch "Super Charge" Batteries · · Score: 2, Interesting

    I would think one of the first uses for this type of thing would be for contractor grade cordless powertools. With current battery tech any heavily used battery lasts less than 2 years with the kind of abuse construction guys give em. Of course you're going to need one heck of an extra alternator to charge em that quickly, more likely a separate generator.

    The biggest problem here is in South West Asia where you have a nuclear armed country without any of it's possible enemies having any nukes. Even if this where not an aggressive country with a talent for making enemies the situation would be dangerous.

    Do you mean Israel in SW Asia? I really don't think they are going to go lobbing nukes. If you meant SE Asia then you should know that Japan has unassembled nukes (well, they used to be unassembled there is rumors that they were assembled after the NK test) and there are plenty of US nukes in SC.

    $100 billion buys a *lot* of nuclear plants

    From the numbers I've seen it buys you about 20 1TWe plants. Those plants would displace ~1/2 million barrels per day, or about 3% of US consumption. I started out to say something about it being a drop in the bucket, but that's actually pretty significant! Do that for a couple years and suddenly you've increased supply enough to consider shifting some significant percentage of vehicles to plugin electric or plugin hybrids.

  12. Re:Hmm. on Boeing 12,000lb Chemical Laser Set to Fry Targets · · Score: 1

    Sorry but I rather think a 12,000lb laser will be a little more powerful than the cannons and howitzer on the current C130 gunship (the AC-130H/U Spectre) against many targets. Now against small soft targets you'd probably prefer the cannons but there is definitely a class of targets for this platform including targets conventional weapons couldn't pray to hit like a field ballistic missile in midflight.

  13. Re:Is the hardware any good though? on Sun Niagara 2 CPU Now Open Source · · Score: 3, Informative

    On the T2 there is one FPU per core, the new FPU's are also accessed in 6 cycles vs the 40 of the T1 and the full ISA is done in hardware (some rare media instructions were emulated in the T1 FPU). The biggest win for the typical customer though is the enhanced crypto performance, now you can do SSL at the rate that the T1 could do normal HTTP.

  14. Re:Home fabbing on Sun Niagara 2 CPU Now Open Source · · Score: 1

    The software's expensive but it's not THAT expensive. Four years ago when I supported Cisco the cost per seat for the design software was in the mid five figure range and support/updates were 20% annual. Kind of made workstation pricing irrelevant, when the designer is making 6 figures and the software is that expensive a $25K workstation that would be amortized over 2-3 years was cheap.

    Where do they not realize a malfunctioning light is an all way stop!? I can't imagine the chaos and accidents that would be caused by people just blowing through the light. Everywhere I've driven during a power outage (mostly midwest) I've seen the vast majority of people obey this rule. Sure some people don't do it correctly and just their turn thus causing a 1-2-1 cross instead of 1-1-1-1 cross but you get that even at 4 way stop signs.

    That's only true where they have designed the onramps wrong, if the ramps are properly spaced and have a sufficient length merge area for cars to get up to speed it works fine. Misdesigning the ramps and adding lights is just shifting the traffic problem from the highway to the ramps and local streets.

  17. Re:Dead tree format is dead on The Home Library Problem Solved · · Score: 1

    Academic works and scholarly reference titles are not (and, with publishers like Routledge, never will be) available.

    I find it's quite the opposite, the scientific community was one of the first ones to jump on digital distribution. Back in 1996-97 when I did an independent science study in high school I found about 2/3rds of my reference materials on Buckminsterfullerenes were available in digital format. Combined with the databases the local universities science library had access to it was MUCH easier than a similar amount of research would have been even a decade prior.

  18. Re:I don't think so. on ISP Inserting Content Into Users' Webpages · · Score: 2, Insightful

    It doesn't have to be illegal to cause you legal headaches. Example: You're surfing a perfectly normal site with no expectations of adult banner ads, but your session is hijacked by your ISP with a less than reputable ad provider. Up pops a banner ad with a risque model just as your female coworker pops into your cube to ask a question. Now you and your company are potentially facing a lawsuit for a hostile work environment. I wonder is Websense et al can detect this type of manipulation in order to protect the corporate networks.

  19. Re:Brings me back to the question.... on Ohio Plans To Encrypt After Data Breach · · Score: 2

    Yeah a county agency (in Ohio) I had as a client was one of the most paranoid I've ever dealt with. The dealt with personally identifiable information of a very sensitive nature and they did things right. Everything was static IP with all LAN information captured to a secure auditing station with IP, MAC and port info recorded. The website their clients (service providers) connected to was behind a good firewall that had rules allowing only a single registered IP to connect from each provider and then used SSL with each agency having a password protected x.509 cert that allowed them access to only their own folder. The data from the website was moved daily via airgap to the LAN, so if somehow the server was compromised only one days uploads would be exposed. It was kind of a pain supporting them because all work had to be done onsite, but I definitely appreciated their thorough approach to security.

  21. Re:Backups Won't Be Encrypted on Ohio Plans To Encrypt After Data Breach · · Score: 1

    I would bet they are also going to use encryption in their backup procedure, either in the backup software (inexpensive licensing but expensive in CPU time and hitting backup windows) or by purchasing new tape libraries/drives with crypto modules (not so cheap, though a few vendors offer it at little extra cost once you've already bought the expensive library).

    Sure it does. The Windows EMF format has all the information needed to create a proper PDF, but the free PDF generators just create a PS file from the EMF and then feed it to Ghostscript or something like it. Or worse they generate a graphic file and shove that into a PDF wrapper.

  23. Re:I am in a Outage RIGHT NOW with NO Cell Service on FCC Requires Backup Power For 210K Cell Towers · · Score: 1

    The problem is in a general blackout you often lose water pressure as well. During the great NE blackout my community has power because of a local generation station and a smart technician who isolated us from the grid. (Which led to LOTS of fun getting home because we were the only place for hundreds of miles with working gas stations). The Cleveland Water Commission decided that generators big enough to run the huge water pumps that power the entire metro area were too expensive and that they would go with multiple power feeds at each of the redundant pumping stations, never planning for a general grid problem. I'm not sure if they've fixed that since but I'm not using my water sump as the only emergency backup =)

    I have a Matrix 5000 with 4 batteries about the size of a large truck battery that came out of our old DR site when we upgraded the UPS there. I'm planning to have it wired in by an electrician to run my blower, sump and fridge during such emergencies. It's always either an ice storm (thus the blower for heat) or a hell of a thunderstorm (thus the sump) that takes out power around here for any length of time. I figure that it will power 2 of the 3 for a day or so as long as I don't open the fridge during the outage.

    How many KVA does a typical cellsite(single provider) need? I'm wondering what sized generators are going to be harder to get. We recently had an almost 90 day wait for our 100KVA set, but I assume that's much larger than a cellsite needs.
