I wasn't saying that this sensor was particulary good because it was high-pixel, EmbeddedJanitor was inquiring as to why one would want a high-pixel count, and I supplied suggestions. However, your points are still valid, pixel count is not the be-all-end-all.
A high pixel count has many benefits. Your effective "zoom" is increased. Low light pictures may be enhanced using DSP. Other grainy photos can be enhanced. Photo editing looks better when done on hi-res images. Also, we are not limited by our monitors with digital photos, it just means we can print better (or larger) pictures.
There are 01 kinds of cars in the world. The General Lee, and everything else.
Thank goodness someone else out there realizes that the standard form of that joke using "10 kinds of _____" refers to not two, but three types of _____.
Yeah, because we all know that marketers should obey the non-standards... Seriously though, there wasn't a standard for binary prefixes, there was a need for one, and now there is one. What kind of problem can you have with that?
Wow, I never realized they could go that fast. We used to OC the celery 300s (I don't know if they were 300a or not) as high as the mobo could go in high school, which was around 475/500MHz IIRC. I always found it odd that there were only a few stability problems (one out of the 5 or 6 machines gave up the ghost a few months later, the rest we backed off to 400MHz and they stayed that way for years.)
Ok, there are eight bits in a byte, one thousand twenty-four bytes in a Kb and one thousand twenty-four Kb in a Mb.
That's actually non-standard. More info available here. In short: according to "the IEEE standard IEEE 1541-2002 (Prefixes for Binary Multiples)" which was elevated to a full-use standard on March 19, 2005, the prefixes you listed, in order should be: kibi and mebi with symbols Ki and Mi.
AFAIK, it is fine to say any of the following: 1 KB=1000 bytes, 1 MB = 1000 KB, 1 Kb = 1000 bits, 1MB = 1000 Kb, 1 KiB = 1024 bytes, 1 MiB = 1024 kibibytes, 1 kibibit = 1024 bits, 1 mebibit = 1024 kibibits, and so on...
That's a nice link you have there. I love how the "lengthy do-it-yourself process" they state is exactly this: "These memory leaks cause Firefox to not release memory that it is no longer using. 1.5.0.1 fixed several memory leaks. If you have not already, you should upgrade to this release."
Heaven forbid you should have to upgrade a release to fix bugs, oh my!</sarcasm>
It's not leaked memory. See Here for details. There is a difference between leaked memory (memory that is completely lost because it will never be deallocated,) and caching (which is what firefox does.)
Seriously though, if it is using 1.5gb of memory, you probably have it to spare, otherwise it wouldn't be using it. If this is still unacceptable, you can TURN IT OFF!
Not everyone lives in areas with such luxury. In rural Saskatchewan if you see a large fire in a field and you phone 911, you will not be put on hold; they will hang up on you and call you back a few (I've seen up to 5 but heard of more) minutes later. Of course, this is because they just call the fire phone and get the fire department to phone you directly. Still, the 911 operator does not take your information or even any details about the fire (including the location!) And why is this you ask? Because they're understaffed and only have a few people taking 911 calls directly.
IRC, is that recorded?
Yes and no. It can be, so assume it is. It is, however, normally recorded by a user or bot on the channel for archival purposes. See http://ds9a.nl/klogbot/ for an example.
I don't know why computer communication isn't given the same legal protections as phone conversations. In most states, intercepting a phone call is illegal, and so is recording them without concent. How is communicating with a computer different than communicating with a phone?
Because in _most_ cases "computer communication" means the Internet and relies on "public" systems to relay messages. Telephone conversations, OTOH, are a "dedicated" connection between two people who have "leased" lines. You can do this with computers as well (even using quantum security, http://www.magiqtech.com/,) but it is not the Internet. In the case of IRC, you are posting to a semi-public forum, not to one person over a private connection.
How can I encrypt my emails so the person recieving can read them, but everyone else can't?
GPG, PGP, etc.
I don't know if you remember, but this is similar to what happened when DVD videos first came out. There were no feature length films (only a demo disc) available when the first DVD players came out (at a price of around US$600!) and look how DVD has fared. True, the didn't have competition that was similar (i.e. Blu-ray) but people were willing to make DVD movies back then when most people pheared another laser disc fiasco. Now that people are more comfortable with movies on discs, in theory, things will work out.
Why not play a card or board game or something else altogether?
It is very easy to "mod" a RL game so that you can even the playing field. Examples follow:
"Risk" like games: Different distribution levels of armies.
"Go" like games: One player starts with more pieces on the board.
"Monopoly" like games: Start one player with a few properties.
I could go on, but you get the point (I hope.)
There are also some games that lend themselves better to n00bs like Cribbage... I can't count the number of times I've been beaten by people who just started playing, and I've been playing it for almost 20 years.
those prices are outrageous for a pc I would just use an old machine for linux, I picked up an old IBM laptop for nothing and it runs linux fine on 192 mb of ram and a pentium 3 400 mhz.
If you don't need a dual P4 Xeon or other high end computer you obviously are not their target market, so don't worry about it. If a PIII-400 suits your needs, fine. I run Linux on a 200MHz ARM in an embedded system because that's all it need to run (more, actually,) but I do the development on a P4-3GHz notebook and it's not nearly enough. Believe it or not, there are people out there who do "need" more processing power than a PIII notebook will provide.
Many. I'd rather not get into it, but I'd say most of the serial protocols listed on this page bring something different and necessary to the table. (Price/Speed/Expandibility/Fault Tolerence tradeoffs) To sum it up, you wouldn't want to use a serial protocol capable of 10Gbps over 100Km of fiber to communicate between your keyboard and your PC.
1. Since when do you use a USB cable to transfer video to your monitor?
2. Most of the 17" LCDs I've seen are >40W (and need high voltages / negative voltages internally for the backlight, which draws a lot of that 40W.)
3. 40W at 5V = 8A == big cable & trickier to fuse. I'm not sure that the connectors on some of the USB cables could handle that.
4. Even if the specification were to allow for 40W on the bus, that would be 40W for the entire hub, not 40W per device attached to a hub (unless the hub was powered from the wall, instead of the device,) and you'd still be wanting more power. "If it can power my monitor, why not my 100W beast-of-a-laptop?"

Devices default to low-power and as such can only pull one "unit load" (100mA.) If a device is configured to be High-power, it can draw five "unit loads" (500mA.) This is at 5V, so it will supply about 2.5W to a device (if you are lucky.)
IEEE 802.3af (better known as Power over Ethernet) would be a much better solution for the applications you mentioned (routers and hubs,) as well as others including IP phones, IP security cameras, and RFID tag readers. It provides power at 48V and around 15W. More info can be found here.
