Comment Re:Curiosity (Score 4, Insightful) 150

If it hits, Opportunity is hosed no matter what. The comet will kick up such a dust cloud that Opportunity's solar panels will not be able to keep it powered. The comet is big enough that it will have a direct effect on the entire planet.

Curiosity, on the other hand, would do fine unless it is unlucky enough to be caught within the blast radius. Note that even if they know now exactly where it will hit, if Curiosity is within the dead zone, they wouldn't be able to do anything about it - it can't move anywhere near fast enough to get out of the way when faced with something this big. The best we'd be able to hope for is that it would be able to get some spectacular shots of the final approach and is able to transmit them fast enough before the end.

That said, assuming it does survive the initial blast (pretty good odds, actually, given just how big a planet really is), having a functional probe on the ground would provide invaluable data about the resulting dust cloud and how it affects the climate.

"...have the Librarian of Congress revisit that decision" != "Make Cell Phone Unlocking Legal"

That is all.

The summary is poor. The petition itself actually states "We ask that the White House ask the Librarian of Congress to rescind this decision, and failing that, champion a bill that makes unlocking permanently legal."

Comment Re:32-bit signed integer? (Score 1) 492

Probably laziness. You need an integer variable, you just use int without thinking about whether the value might ever go negative or not. This probably happens all the time, but it is extremely rare that it actually becomes an issue. After all, a signed int can store a number up to just above 2 billion - how often do you need to store numbers even approaching that big? The same thing happened in World of Warcraft with gold. For a while, the gold cap was (2^31)-2 copper (which translates to 214,748 gold, 36 silver, 46 copper) - which indicates they used a signed int despite the fact that it's impossible to have a negative value of money in the game.

At some point (I'm not sure exactly when, but I think it was during the Wrath of the Lich King years), they changed it to use a 64-bit value, and the gold cap is now 1 copper shy of 1 million gold. That was an artificial limitation - there's no real reason why they couldn't just use the entire 64 bits if they wanted to - I don't think anyone would ever be able to reach the 2^63 (assuming a signed 64-bit integer) that it could store.

Something to keep in mind is that spy satellites looking down have the same problem that astronomical ground-based telescopes have looking up. Specifically, they have to look through the atmosphere, and the distortion that causes puts a pretty firm upper limit on how clear images can be. Yes, there are tricks that can be done to minimize the issue, but those tricks only go so far. I doubt they'll ever be able to read a newspaper from orbit.

That's why Hubble was useful in the first place. As a telescope, it's not that impressive - far bigger and fancier ones exist. What sets it apart is that it is above all that atmospheric interference.

Comment Re:Lenovo T400 does not meet WoW's minimum require (Score 1) 503

Ok, so the Mobility Radeon HD3400 is slightly better than the GMA 4500, enough that it does technically make the cut for meeting WoW's minimum requirements, but it is still an underperforming, dated chipset. Performance in WoW will still be sub-par. And yes, I have first-hand experience with the HD3400.

Seriously, do your kids a favor and get them a new computer with Windows 7 (or even Windows 8) preinstalled. A $500 desktop machine will do just fine, and won't spoil them in the "beefy" category.

Comment Lenovo T400 does not meet WoW's minimum requiremen (Score 3, Informative) 503

See title. I feel it important to point out that the Lenovo T400 does not meet World of Warcraft's minimum requirements. The Intel GMA 4500 GPU that this laptop has is specifically listed on Blizzard's website as not being supported. What this means is that even if you manage to get it to run, performance will be poor and the game really won't be any fun. In fact, I have to wonder if the problems you've had related to getting it to run in wine are more hardware-related - the computers you are trying to do this on simply aren't beefy enough.

Other specs on the system are borderline bottom for barely meeting the requirements. Don't subject your kids to that. Get them a new computer with Windows 7 preinstalled. For virus protection, Microsoft Security Essentials does fine (free with Windows 7, though it is a separate download).

You may prefer Linux, and it may even work for you, and for you that is fine. But we live in a Windows world - you are doing your kids a serious disservice by not giving them Windows exposure now. They'll need that experience in 10 years when they are trying to get a job - any job - that isn't Linux development.

Comment Linked story lacking in details (Score 2) 307

The linked story is distinctly lacking in details. Yes, it mentions the red or green license plate requirements, but I consider that to be a minor requirement that says nothing about the actual operation. This story has more interesting information and it doesn't even mention the license plate requirement.

Among the highlights:
  • In the test vehicles (presumably the ones with red plates), there must be 2 people in the vehicle at all times, with one able to immediately take over control.
  • Companies must register their testing intentions with the state, such as testing in fog or snow/ice. They must also share results with the state.
  • There must be a "black box" type data recorder that records and stores all sensor data for 30 seconds prior to a collision.
  • Once a vehicle is certified to operate without a driver, a person can operate it without being physically present in the vehicle.
  • The operator is liable regardless of whether they are present or not.
  • There are exceptions for operating an autonomous vehicle while talking on a cell phone (illegal in Nevada without a hands-free device) or texting (also illegal to do while driving), but not for being drunk.

Seems like reasonable rules to me.

Comment Definitely check out the Mormons (Score 2) 292

Any software you find is likely just going to be a database entry/maintenance type software tool for storing your genealogical information, but itself will not give you any information; it just provides a place for you to keep track of information you do find from other sources.

If you are stuck on open-source, I'm not sure how to help you, but if all you really care about is that it is free, I can strongly recommend Personal Ancestral File from here. While it has some fields for Mormon ordinances, you don't have to use those features and it will do nicely to maintain your records.

As for doing the actual research, again I recommend looking into the Mormons - they maintain branches of their main family history library at various church buildings around the world. The volunteers who staff those branches are instructed to not proselyte, they simply are there to help you do the research. The only time you'll have to pay for something is for obvious things like using the copy machine, or if you want to have records shipped in from Salt Lake City you'll have to pay postage, but that's it.

Disclaimer: yes, I am a Mormon, so I may be biased on this matter, but as far as I've seen, the Mormons are the premier experts in the world when it comes to family history research.

Comment Display Port? No thank you. (Score 4, Interesting) 356

I work as a student employee at my university. Over the last summer, we replaced about 500 computers across campus (most of our student lab machines). The new machines only have Display Port as their graphics interface, and we have had lots of problems with it. Lots of various software glitches, and even some significant hardware issues as well.

One issue is that the physical connector is not very sturdy. One good whap (which is not uncommon in an academic environment) and the connector gets destroyed, sometimes taking the graphics card with it. We've had to replace several graphics cards because of this. This was not a problem with our previous batch of machines, which used *gasp* VGA. There are other issues as well, such that there was actually some serious discussion at upper levels of management about the possibility of returning the whole lot of computers (remember, about 500) and demanding the replacement use either VGA or DVI. In the end, they decided that this would be more trouble than it was worth, and that we'd just deal with Display Port issues as they arise. Which, they continue to do.

As for myself, I have no intention of ever using Display Port as my primary display interface on my personal machines unless there is literally no other option. In my opinion, DVI is superior in every respect that matters, and even VGA is preferable.

Comment Do not want (Score 1) 381

I rarely watch movies in the theater. The last one was Toy Story 3, which I saw with my wife. We were rather annoyed with the fact that we had to go out of our way to find a screen showing it in 2D, as it seemed everyone just wanted to show it in 3D.

Even if it was cheaper, I wouldn't want to watch it in 3D. It's a gimmick, and one that gives me headaches at that. If there were no screens showing it in 2D, we would have skipped it and waited for it to come out on video. This will forever be true for me - if moviemakers decide that every movie should be 3D, then my days of going to the theater are done. Now that I have a nice HDTV at home, the desire to go to the theater is lessened, anyway.

I hope more producers take the stance against it that Christopher Nolan has - then maybe we'll see some sanity in the industry about it. Maybe that's a tall order, but I hope not.

Comment A conversion table (Score 5, Informative) 465

Assuming a height of 5'6" (1.68 meters), the units convert like this:

3000 heights = 3.125 miles = 5.03 kilometers
6000 heights = 6.25 miles = 10.06 kilometers
9000 heights = 9.375 miles = 15.09 kilometers
12000 heights = 12.5 miles = 20.12 kilometers
15000 heights = 15.675 miles = 25.15 kilometers

Pretty much, unless you are in the city you were born in, your answer should be more than 15,000.

According to Google Maps, I am 1,234 miles by car from where I was born. I am 6 feet tall, which means I am 1,085,920 heights from my birthplace.

Comment Count me out from Ubisoft titles that do this (Score 1) 631

I've only ever purchased one Ubisoft title, and that was Beyond Good and Evil for the GameCube. I rather enjoyed this game, and am excited that a sequel is in development, though likely still a few years from being released. However, it seems unlikely that they will release a Wii version of BG&E2, which means that I was going to be dependent on getting the PC version to enjoy the game. However, if it winds up with the limitations of this draconian DRM, then I will pass on it entirely.

People have often complained about Steam doing similar things. However, in the case of Steam, it at least has an offline mode. You get authenticated against the server, and then you can play your games offline. I'm fine with the way Steam does things - my only real complaint is the lack of aftermarket sales, but I've never bought a used game anyway so it doesn't really affect me.

No single-player game should ever require an active Internet connection to play. Sure, it can be supported, allowing for saving progress on the server, but not required.

Comment Re:Mount Evans Road (Score 2, Interesting) 197

I've never been on Mt. Evans, but being from Colorado Springs (at the base of Pikes Peak), I have driven up Pikes Peak. Not as a racer, mind you, just as a tourist, in my '02 Saturn SL2.

It's not a simple road. Even going slowly, you definitely have to pay attention. Lots of loose gravel and dirt where a moments inattention can result in a skid where you go driving right off the side of the mountain. And as others have pointed out, the difference in elevation wreaks havoc on engine efficiency - going from about 8000 feet elevation at the toll gate to just over 14000 feet at the summit, my car was noticeably more sluggish near the top than it usually is (Colorado Springs, where I do most of my driving, averages at about 6500 feet). As an indication of the hazards of the road, every once in a while there is a local news report of someone driving off the road to their doom.

Every summer, there is an organized race up the mountain, the Annual Pikes Peak Hill Climb. I assume that this robot will be doing its thing during that race. I look forward to hearing about how well it does.
