I thought about modding parent up for mentioning the downside to RAID5 with modern hard drives but it was an AC with a score of 0 so most still wouldn't have read it.

So I'll just do it myself and link to http://www.baarf.com/

I still don't understand why so many people use RAID 5 when disks and controllers are cheap enought to do RAID 10 or multiple RAID 1 arrays instead. And if you are using enough data that RAID 10 doesn't do it for you then RAID 6 might be a OK solution but I wouldn't recommend any RAID solution unconditionally.

I will unconditionally recommend against RAID 5 though. And in a similar train of though I'll conditionally recommend against RAID 0 (though it does have valid uses it's often used by those that don't understand the down sides).

Keep in mind the concorde needs a very long runway and operated at only the largest airports were it would have to wait in line and/or travel a long way from loading to takeoff at low speeds which is very inneficient for a jet engine.

Acording to Wikipedia due to jet engines being highly inefficient at low speeds, Concorde burned two tonnes of fuel (almost 2% of the maximum fuel load) taxiing to the runway.

According to http://news.bbc.co.uk/2/hi/business/5195964.stm the Concorde burned up 94 tonnes of fuel getting from London to New York and a whopping two tonnes simply taxiing onto the runway.

A random google result says a 737 uses 2400 kg/hour in fuel and 1 hour at 485 mph, 780 km/h should get you about 485 miles / 780 km :)

London to Amsterdam is only 221 miles (356 km) so it looks like Concorde as designed in the 50s used more fuel taxiing around as a common jet does in an hour flight

but then I don't see an advantage of the laser over a chain gun.

How about no ammo rack explosions? OK I pulled that term from a game but ammo does explode no matter how it is stored (rack or otherwise). Assuming the power for the laser is deep within the ship and wires transmit power I'd wager it'll be safer than having ammo at various points on the ship.

I was with you until you said kitchen. Buy a scale that isn't digital and try to measure flour, water, sugar, salt, yeast, oil in grams or ounces as needed. Sure you can get a analog scale to do that but it'll likely have a dial readout that is inaccurate or nearly impossible to read to the level of accuracy you need to bake with.

For example a 14" Pizza with

325g water
435g whole wheat flour
23g oil
18g sugar
7g salt
0.42g yeast.

OK, even my digital scale won't do the yeast. I have to measure that with partial teaspoons like 1/8th because the scale only goes down to 1g. But you'd have to have a scale that would be very large to get the accuracy I need for dough making and not be digital or it'd just have a very low upper limit. It's rather easy for a digital scale to show small and large numbers accurately.

I guess ovens ride the line as the elements on top have analog dials but the oven has digital controls. I can't imagine having to use digital controls for the burners/elements on a stove but I much prefer digital controls for baking.

hmm my can opener isn't electric. I crank the knob just like anyone else but even an electric can opener isn't digital unless you want to count on = 1 and off = 0 and start sending Morse code with a can opener. Maybe if you said you avoid electric tools instead of digital technology I would agree on the can opener at least.

I'm using Libre Office 3.3 and spell check works perfectly. I'm using XP SP3 32 bit so it's a different OS but it does work.

US Embassy Categorizes Beijing Air Quality As 'Crazy Bad' Screenshot-sm 270

digitaldc writes "Pollution in Beijing was so bad Friday the US embassy, which has been independently monitoring air quality, ran out of conventional adjectives to describe it, at one point saying it was 'crazy bad.' The embassy later deleted the phrase, saying it was an 'incorrect' description and it would revise the language to use when the air quality index goes above 500, its highest point and a level considered hazardous for all people by US standards. The hazardous haze has forced schools to stop outdoor exercises, and health experts asked residents, especially those with respiratory problems, the elderly and children, to stay indoors."

Tell me about it. I was intermittently losing connectivity with a docsis 1.1 modem that was giving me 4+ mbit most of the time. The tech I called recommended I get a Docsis 3 modem so I did. I no longer have connectivity issues so it was a good call by the tech but I'm still seeing 2.x to 4.x mbit downloads and getting 0.3 Mbit uploads at best.

I called back after getting the new modem to get it provisioned, then called the next day after running speedtests. They said I should expect closer to 7mbit down instead of the 2 to 4 I'm getting but DOCSIS 3 would hit my area in the next few weeks taking the advertised to 12 Mbit down. So if I'm getting half the advertised speed I'll still see my download speed double if all they do is bond 2 channels for me.

Girl Quits On Dry Erase Board a Hoax Screenshot-sm 147

suraj.sun writes "It's the same old story: young woman quits, uses dry erase board and series of pictures to let entire office know the boss is a sexist pig, exposes his love of playing FarmVille during work hours." Story seem too good to be true? It probably is, at least according to writer Peter Kafka. Even so, Jay Leno and Good Morning America have already reached out to "Jenny."

Submission + - I've Fallen and I Can't Get Up 2.0 1

theodp writes: Remember those old Lifecall commercials? Well, you've come a long way, Grandma! The NY Times reports on a raft of new technology that's making it possible for adult children to remotely monitor to a stunningly precise degree the daily movements and habits of their aging parents. The purpose is to provide enough supervision to allow elderly people to stay in their homes rather than move to an assisted-living facility or nursing home. Systems like GrandCare, BeClose, QuietCare, and MedMinder allow families to keep tabs on Mom and Dad's whereabouts, and make sure they take their meds. Perhaps Zynga can make a game out of all this — GeriatricVille?

Nuclear Energy Now More Expensive Than Solar 635

js_sebastian writes "According to an article on the New York Times, a historical cross-over has occurred because of the declining costs of solar vs. the increasing costs of nuclear energy: solar, hardly the cheapest of renewable technologies, is now cheaper than nuclear, at around 16 cents per kilowatt hour. Furthermore, the NY Times reports that financial markets will not finance the construction of nuclear power plants unless the risk of default (which is historically as high as 50 percent for the nuclear industry) is externalized to someone else through federal loan guarantees or ratepayer funding. The bottom line seems to be that nuclear is simply not competitive, and the push from the US government to subsidize it seems to be forcing the wrong choice on the market."

Mom Arrested After Son Makes Dry Ice "Bombs" 571

formfeed writes "Police were called to a house in Omaha where a 14-year-old made some 'dry ice bombs' (dry ice in soda bottles). Since his mom knew about it, she is now facing felony charges for child endangment and possession of a destructive device. From the article: 'Assistant Douglas County Attorney Eric Wells said the boy admitted to making the bomb and that his mother knew he was doing so. The boy was set to appear Tuesday afternoon in juvenile court, accused of possessing a destructive device.'" She's lucky they didn't find the baking soda volcano in the basement.

Comment Re:Dell SOLD Fauly PCs (Score 1) 484

The Summary is misleading but the problem didn't end in 2005.

Replacement parts were just as faulty as the original parts and continued to be shipped to customers at least 4 years after they started selling new PCs with those parts and a least a year or two after warranties expired. Worse for people that didn't have warranty coverage and paid hundreds of dollars for a replacement motherboard. It's bad enough when you get your replacement part for "free" and it works worse than what you had before, it's even worse when you pay hundreds of dollars for a replacement part that doesn't work properly.

Now you can talk about how stupid it is to buy a replacement motherboard from Dell when a new PC is only a few dollars more but we are talking about businesses here. Full of stupid procedures that waste money on a regular basis.

I'll add to the trivia here by mentioning the there is a revision of the GX270 that has the same motherboard as a revision of the GX280. I wouldn't know except I worked for a corporation that had hundreds of PCs in the GX260, GX270, GX280 models and management made the bad decision of replacing all motherboards "proactively" (the catch being this was a reactionary way of going proactive, any other time I'd ask them to be proactive they'd avoid it). So we literally sent away working motherboards with no observed issue only to receive replacement motherboards with even worse bad caps on them and got into situations where Dell had already taken away the good motherboard couldn't replace the bad replacement motherboard due to shortage of parts.

I'm at a different company now but even here we have a handful of those bad cap Dells in daily use. If we keep up the pace of PC replacements the last of the 2005 bad caps PCs will be replaced here some time in 2011. I wouldn't have to assume there are millions of these junky PCs still in use in businesses of all sizes, homes, churches, and schools across the US. Think about how many companies provide PCs for telecommuting or donate PCs to schools/churches/employees. These things are like the PC equivalent of a cockroach.
