This means a new standard, and new players all round. It's no longer a DVD, and I'm certainly not running out and buying a new player for it.
I'm not buying any new players until after the HD-DVD/Blu-Ray competition is done with. Come to think of it, I'm pretty much not buying any more movies either right now. Of course this reduces the pressure on me to upgrade to an HD TV. And at this point, I probably won't get an HD TV until after the format war is settled unless my current TV dies.
People don't listen. The worst part... when their name brand unit dies... AND THEY DO IT AGAIN!
Of course if they bought a better quality name brand unit, it wouldn't die. My DVD player still works and it's one the original models (but after they dropped in price).
But I do agree, people tend to buy things for the name on it, and not necessarily what is in it. I tend to buy for both name and contents. Some brands do have better reputations than others.
For an example of buying by name, but not fully for content - Volvo makes cars that are very safe, however the last time I checked they still had lousy repair records, so what good is a safe car if you're always bringing it in for repair?
Also to add to the question of MP count vs Quality is the size of the sensor.
(Roughly speaking:)
A larger 6 MP sensor will in general give a better image than a smaller 6 MP sensor.
Given two sensors that are the same size, the sensor with a larger pixel count has smaller pixels. A smaller pixel gets less light to sample. So at some point more pixels won't get you a better image at a given sensor size.
Over time the technology is impoving so a sensor of a given size and pixel count can be in general designed better over time.
Digital SLRs use large sensors than compact digital cameras, so in general an SLR wil give a better picture. (Ignoring all the other factors like the person handling the camera, quality of the lens (some campact cameras have lenses that are better than the least expensive SLR lenses).
Why is there a metal part on a TOSLink connector? More to the point, why do I care if it corrodes?
My guess the metal would be for structural integrity. And as for why you might care - well if it corrodes, it can impact proper seating of the of the connector in the recepticle.
VHS versus Betamax took a noticeable amount of time before one format won out.
With 12" video discs there were 3 competing formats. The Pioneer 12" Laserdisc won that and fairly quickly. DVDs killed the 12" Laserdisc.
CDs pretty much killed all but killed off vinyl record, but it took time.
DVDs killed VHS.
Now we have the battle of the HD formats. This will probably be in length of time much like the VHS versus Betamax battle. And add to that the fact that not everyone will be jumping right out to buy a new TV. I keep looking at how nice the plasma screens are, but I can't justify the price yet. When my current TV dies I will end up with a plasma scrren. However with all the changes, including the HDMI connector, I'm glad I haven't bought one yet.
However, one thing that I know is that a bunch of people have stopped buying as many DVDs as they used to. Why buy a DVD now and then want to replace it next year with a high def version? of course if enough people do that, movie sales will drop even more and then the MPAA will start screaming piracy since their sales fell off. Maybe everybody should boycott buying movies until their is only one new format?
I once had a salesman try to upsell me on a gold plated toslink optical cable. I had to leave the store I was laughing so hard.
Why do they even make those?
So they can charge way too much money for their well known brand item?
Actually again so the metal part doesn't corrode.However, I bought a $6 (US) toslink cable from Amazon and it is gold plated. So there is no need to spend excesive amounts of money for that either.
However, go to Radio Shack or even Home Depot and pay a lot less for the cables with gold plated connectors.
Buying cables from a well known brand at a hefty price premium often isn't worth it. Paying only an extra dollar or two for a cable that has connectors that are resistant to corrosion is often worth it.
In short gold plated is worth it, but not at the well known brand over inflated price.
Why not just create an algorithm with more rounds? I'm sure it would have more benefits than just slapping two algorithms together.
Thi smight be good is the number that was output was two seperate numbers concatenated together. Otherwise it's still just one number they have to match when they are modifying the hash protected data.
1) Message/file length 2) SHA1 hash 3) MD5 checksum or some other hash/checksum that's calculated way differently from SHA1.
Providing the length means that the person trying to change the data needs to keep it the same length which makes it more difficult.
Using 2 different hashing/checksumming methods means they have to be able to match both of them in order to be able to switch the data.
The more restrictrictsion we toss on the data, the harder it is to manipulate. I do think that using more than 2 or 3 hashing/checksumming methods would be overkill however.
After a while, I'll normally find that one of the books is easiest for me to understand, so I will focus on that one but refer to the others when I need clarification.
I did the same thing using two calculus books. The two books were complementary to each other as they each explained different things better.
Nowadays with computer stuff, one book usually for the main reference and then look up stuff online if more detail is needed.
And it's still faster skimming through a printed book to find things than searching online in a lot of cases. Also highlighters don't work well on a screen.
Actually on a Mac, officially all you need is a dual proc or a dual core (2.0GHz or faster) to run 1080p.
In reality a Dual 1.42GHz G4 can play back 1080p just fine.
The current dual core mac mini at 1.66GHz probably can play back HD content without much issue. And I suspect the next updates to the Mac mini will allow them all to play HD content.
Power outages do happen. What happens when there's an extended power outage and all the toilets in a house require electricity to operate?
Do pepole have to hold it in? FInd a neighbor with an old fashioned toilet? Or do they use their toilet and hope power returns before the toilets overflow?
Would it theoretically be better to build new from scratch using OO or some other suite? Sure. Can we afford the down-time and development costs required to do so? No.
Just a thought, but why would it really require downtime?
All you have to do is install OpenOffice on the users computers and then work on one task at a time. After all the files/procedures are converted you would then switch them to Linux.
Besides if it is really that patched together it may just very well be time to start rewriting stuff so it's easier to maintain.
The ealry NASA engineers probably learned to use sliderules - http://www.hpmuseum.org/sliderul.htm and therefore learned how to approximate real well.
If you punch numbers into a calculator and hit the wrong buttons and don't know how to approximate... well you don't always realize your answer is off.

Actually the problem with the *AA is how they're going about lawsuits.
Actually you do want to consider an HD TV at that point. Unless you think it'll be more than 5 years befoe you'll be buying an HD TV.

Heck, iTunes couldn't even find covers for about half my music collection.
In a related rant, that's paritally why we don't have more fuel efficient (or alternative to gasoline) cars now.

Actully I think you mean shouldn't they have evidence before they file a lawsuit...

Gold plated connecters really are better.

The question should be: How much swap space is enough?
/tmp in "memory" - so that takes up swapspace as well.
And the answer depends on a lot of things. This includes the usual questions of what programs and how many concurrently.
And of course some Unix variants have
So it looks like they found a way to get even more money out of an old series. I guess there aren't too many people left who want to buy the DVDs.
However, even on HD it will have to be at the 4:3 aspect ratio to match what it was shot in.
Unless they're going to play with it to make it a widescreen show.
Thi smight be good is the number that was output was two seperate numbers concatenated together. Otherwise it's still just one number they have to match when they are modifying the hash protected data.
Actually when you going for data verification of non-secret data, more precise information is better.
Provide the following 3 pieces of data:
1) Message/file length
2) SHA1 hash
3) MD5 checksum or some other hash/checksum that's calculated way differently from SHA1.
Providing the length means that the person trying to change the data needs to keep it the same length which makes it more difficult.

In my case, it will be as hardware gets replaced. Either when the hardware dies or needs replacement because it can't do it's job anymore.
The wireless base will most likely get replaced when it dies. The laptop will get replaced when my needs outweight it's capabilities.
I upgraded from 802.11b to 802.11g when my wireless base died. At that point my laptop already had 802.11g capability.
