Question for you. Why is it that the beer companies always have the best commercials? It seems like the best ones they have don't even have a beer in them, just their logo at the end.
First, learn how to design circuits in general. It won't matter what the underlying technology is after that, you can learn to use any of them. The hard part is learning how to design them in the first place. I took a class on how to design silicon chips my senior year. Give me a new technology and it won't take me long to pick up the new features not that I understand the basics.
Nevermind the growing heat concern. Who was it that said soon microchips will be hotter than the surface of the sun if they keep getting faster at the same rate they are now?
That's assuming that power consumption continues to increase inside the silicon chip. With these switches, using different materials all together, power consumption is supposed to be greatly reduced. What you're doing is similar to comparing a statement made about vacum tubes to transistors.
Ok, I guess I should clarify a little, the 10x is a bit of an exageration, but not by much, with some of the service contracts in the hardware. Some of the places are 20 miles from nowhere. A three hour drive to the airport would not be unreasonable and all of these places were scatered throughout the country (in every state). Some of the Alaskan sites would require a chartered flight to take you there as there are no regular flights. So we are talking some very remote places.
As for Apache, that's one example that doesn't require much support. Lets consider database servers that aren't loading up or an ordering system that just crashed and the fixes require tweaking some obscure configuration file that only the coders ever heard of or editing the registry. There are some very interesting things that can happen to computers and redundancy doesn't always solve the problem. Especially in places where space or power consumption/disipation is at a premium. Datacenters count every watt for both power bills and cooling. While the place I worked at wasn't a datacenter, the power bills were easily over $10k/month and the cooling system for the equipment dubed as the heating system.
The reason why open source vendors who act more like "real" companies do well is because corporate IT absolutely demands that they have someone to complain to when everything goes to hell. Imagine you're the CIO of a 25,000 person company who depends on its IT systems to make money. I think you'd be foolish to trust that the crew of experts you hired is going to stick around, and be able to solve any problem that comes up. Sooner or later, something high-profile will die. Who do you call??
Absolutely true. The last place I worked at was willing to buy products at 10x the price, so long as they had garunteed vendor support. Never underestimate how valuable a support contract is when your last parity drive has just failed on your raid and you have no spares left in the building.
Current patent law has a patent lasting for 20 years, this is fine, it's Copyright lifetimes that are the problem, with a "life of the author plus 50 years".
You don't have a refrigerator ?
That's typically the biggest power draw by far in any house (unless your computer is an IBM system/370).
Ovens and Dryers typically have a higher power draw than a fridge. They're also on their own circuit. Most fridges I have seen plug into the standard 120v circuit.
ou have only three of each type of 'nade IIRC. I've been informed by multiple individuals who are in a position to know that usually, you carry an unbalanced load, and usually at least three frag nades per squad member, not just everything being carried by one grenadier who carries an M4M203.
Thankyou, that's the information I needed. I forgot to mention I have never played the game before so I had not idea what was unrealistic about it.
No word on specific differences between the video game and the simulation, but there are some pretty unrealistic elements to the game (like your severely limited supply of grenades.
Can you expand on this? A limited supply of grenades is realistic. What makes it severely limited and unrealistic?
I feel the whole idea of degrading accuracy of GPS to be quite silly.
So did the military after some thought. They stoped degrading the signal of GPS years ago when they realised they could turn off the civilian portion with the "flick of a switch". The only reason the civilian portion of the system is only accurate to 10 meters is due to the low cost manufacturing of the electronics and not being able to detect mroe satelites. Want a more accurate GPS unit? Be prepared to pay more for it or get a better signal.
The RAID-5 would be redundant in most cases. A business that really wants to keep the data will have duplicate tapes (simulating RAID-1?) in at least two different storage wharehouses. Given that, I don't think the RAID-5 would be necessary.
Also, given the ECC already in the LTO format, and that you can put some in the cmpressed file, RAID-5 would probably be a bit too exotic on tape to include.
LTO tapes aren't really made for online storage. Nearline at best and usually archival storage is how they are used. For most archives, you don't need a tape library to hold all the tapes. This is especially true if you are storing old customer records. Generally you'd take tapes like that out of the tape library and store them someplace else.
As to the restoration of data you talk about, it is interesting. One thing is that the max transfer speed I know of for any single drive hookup is 2Gbit/s. The limit of 250MB/s would hamper large restores.
LTO tape has built in ECC. The data retains integrety the longest by keeping the tapes in temperature/humidity controled rooms and, most importantly, by not reading the data. Tapes are very good for long term storage this way.
On tape, this is not an issue. Serious tape libraries are automated. An arm manually loads in and extracts tapes used in backup. Mind you, I'm also assuming that any one really worrying about this is going to be "serious". LTO tapes (great for long term backup) hold 400GB (LTO3). Transfer speed is about 20MB/s (yes, megabytes). Tapes cost ~$100 each. Also, from my experience with compression, no compression algorithms (or computer hardware) can compress raw data fast enough to keep that rate up. It's going to stay a save money on tape/storage costs for the forseable future as far as I can tell.
In this day and age, when magnetic storage is like $0.50 to $0.75 per GIGABYTE, I just can't fathom why a responsible admin would risk the possible data corruption that could come with compression.
Because when you are storing Petabytes of information it makes a difference in cost.
Besides, all the problems you mention with data coruption can be solved by backing up the information more than once. Anyplace that places a high value on there info is going to have multiple backups in multiple places anyways. The most usefull application of compression is in archiving old customer records. Being mostly text, you can easily get above 50% compression ratios. Also, these are going to be backed up to tape (not disk). Being able to reduce the volume of tapes being stored by 50% can save a lot of money for a large organization.
and am I correct to say that the U.S. army actually helped make it or am I mistaken?
The only video game I know of that the US Army (or any DoD agency) helped to create was "America's Army". Given what I have seen of many games out there, this one is quite tame in comparison.
I think you might have missed part of what the parent said in Problem one. While the movies do have their rating system, a movie theatre won't get in troble for selling a PG-13 ticket to a 17 year old. Apparently with video games they can get in trouble for selling a Teen movie to a 17 year old.
These bones are said to have been sent to Holland without authorisation from some local authorities who deal with issues of National Heritage. It was not known if these remains were stolen or sent abroad secretly.
Third possibility:
The reasearchers didn't inform the bureaucrats because they didn't think they needed to?
Along the lines of what you say, I'm surprised more people don't doubt history more often. How do we know what really happened a thousand years ago? No one is still alive from then, all we have are the words people have left behind. How do we know it is true (and not faked for that matter)? Seems like a lot of things can fall into this category.
You don't need something as fancy as a power inverter. There are several third-party power adapters for the GBA that plug into the cigarette lighter.
Buy the inverter and you can use the ac adapter when you get out of the car. Besides, I kind of figured that a poster on slashdot would have a laptop or other electronic gadget they used in cars and would already have an inverter.
Ah, Pokemon. I still need to beat a few of those. I'd recomend you buy a power inverter for your car and an AC adapter for the gameboys. It'll save you a few hundred on batteries.

We meddled with nature when we introduced predators they were not capable of handling.
The predator was Homo Sapiens Sapiens. They made good eating after months on sea-rations.

Ah, Pokemon. I still need to beat a few of those. I'd recomend you buy a power inverter for your car and an AC adapter for the gameboys. It'll save you a few hundred on batteries.
I'd have to agree with your ranking
1) Seagate
2) Maxtor
3) Western Digital
I've only had one Maxtor fail on me, and that was after 4 years of continuos usage in my desktop (which was rebooted, but never off for long).
I love the seagates I've been using since they are quite (I'm runnin SATA). Next time you need a drive, give them a shot.
As for WD? The one drive I bought from them failed the same day.
