Actually, a lot of audiophile grade records are direct to disc. No digital step, no analog tape mixing... see: Direct to disc
Anyway, this article is a good way to show how the CD's resolution is quite limited, compared to the original analog waveform. And it shows that new digital format are much more closer to the original.
Probably too late for someone actually reading this comment but...
I read not long ago that the Library of Congress chose to stay analog for the archival of sound recording, because they haven't found ANY digital format and media that they think will still be usable in a distant future.
Analog reel-to-reel recordings from 50 years ago are still usable (think Elvis 30 #1), compared to DAT recordings from 10 years ago that are completely lost due to poor media. Hey, 78rpm disks and wax recordings from 70-80 years ago are still good!
So, I say copy your VHS tapes to 3/4" video, pretty cheap and it'll last for 20-30 years...
Wich explain the difference between analog and digital. The graphic example given clearly demonstrate that even at 10Khz, the CD gives only a raw approximation of a wave. If you go up to the theorical 22Khz, you must understand that you only have one sample per oscillon of a sine wave for example. So at these frequencies, a sine wave, square wave of triangle wave all sound the same. Imagine a complex wave full of harmonics from a musical instrument (or 20 instruments at once). All this detail get lost.
Sure, the dynamic range and noise floor is a lot better on CD than vinyl, but the resolution is awful.
Maybe SACD will give us better music and less bits.
Yes, a datawarehouse eats up a lot of space, but it needs speed too.
That's why in my company we prefer buying a lot of smaller drives than one bigger drive, because the disk usage will be evenly spread between all the units.
But we could surely use a lot of 320Gb drives and do a multi-terabyte RAID!!!
Do Cathloic priests do the same as muslim clerics and convince children they should go blow up a bus full of families, because they don't believe in the same faith?
Of course, we all know that catholic priests are very good with childrens...
Take cars for example, it's possible for a big company like GM to create a new car in a couple of weeks. But they have to give a warranty on it, and they have to make certain that the car is safe. So they spend months and months of testing the car in every immaginable way. They have to be sure that the car will be free from serious defects for at least the lenght of the warranty, but more than that for the safety (or they'll have costly recalls!).
You can do the same with software, where I work the testing time is often 3 to 4 times longer than the time it took to develop the program. So you have projects that took 1 month to make but 3 months to test. That's expensive but a bug in calculating interests for example can be a lot more expensive than that if you discover it a couple of years later!
You are correct, but I must say that the Germanium diode you are talking about must be considered as an external source of randomness, since it's not something normally found in a computer.
What I meant to say is that in today's personal computers, there is nothing truely random.
Video poker machines have been exploited because the random numbers they generates tend to repeat. When you sample those numbers over a couple of weeks, you can see patterns emerging from those numbers. If you can find a formula or method that duplicates theses patterns, you have a way to predict the "random" numbers that the machine will generate.
A computer can do pseudo randomness... but since it's not truly random there are ways to detect periodic repetitions and thus find the missing key to decrypt the message...
The only way to be truly random would be to have an outside source (like a camera pointing to lava lamps, or a tree in the wind, backgroud noise, etc...).
This article is not very detailed, but I understand this invention is in the process of being patented, so we'll have to wait...
Back in 1998, we had here in the province of Quebec (in Canada) a winter storm that took down a lot of the electric company infrastructure, resulting in the biggest power outage in Quebec's history (about 1,300,000 persons without electricity). In 6 days we received 80mm of freezing rain.
Like I said, this was in winter and the outside temperature was about -30 (Celsius). The temperature inside the house dropped to below freezing in about 24 hours.
In the town that I lived at the time, Boucherville, the mayor decided to do something quick to bring back power. They took a crane, lifted the locomotive from the track, put it down on the road, on it rolled on it's power on the asphalt. Then it was connected and it gave power for a couple of weeks.
Went I moved last year, you could still see the trails that the locomotive's wheels made in the asphalt...
I'm tired of seeing you brag about your pickup rocket.
Your 440 cid engine was rated at 225 HP @4000rpm and 330 lb/feet torque @2400 rmp in 1976.
Your truck weight a little over 4000 lb.
Putting that into the cartest software (with a 3 speed automatic) gives a 1/4 mile time of 16.7s.
To obtain the number you gave, 12.8s, would require you to have a MUCH more powerful engine, and at least drag slicks.
Now, let's take a 2.3l turbo engine, say in a Merkur Xr4Ti (american version of the ford sierra). It put out 170hp, and it can do 16s on the 1/4 mile. And that's an old 80's car.
Explain to me then how can you claim such numbers. Can I see a time slip, a video, some way to calculate this?
Understand me, I love big engines and the sound of a 400+ cid car shredding it's tires at the red light...
Muscle cars are quick, but when you compare them to the modern cars, they tend to show their age. A modern Nissan Altima with it's 260Hp 3.5l V-6 can outrun a lot of old muscle cars... and it's a family sedan. Or take the small 5 liter engine in a BMW M5, 400hp!!!
It's just the technology improving year after year. I would love to see what a modern engine with 440 cid could spit out, 700hp? It would be a blast (and maybe a little dangerous) to drive.
Cheers! (and your are welcome to correct my spelling, english is my second language)
1- don't use those small 5" b/w tv's as monitors 2- small printouts on rolls of paper are lame too 3- tight costumes for men are a no-no (but ok for women) 4- try to have at least one crew member with psychic abilities, it may come handy when confronted to strange alien life forms
- work anywhere on earth - good sound - have at least 8 hours active battery life (and more standby) - is small, light and durable - and cost 20$ a month unlimited connection.
If you give me that I'll drop my regular phone line and you have me as a customer for the rest of my life...
If I want to see moving pictures in color I'll turn my TV on... you wanna bet that those features are there to bombard you with shiny colorful advertisement!!!
I think I'm quite the opposite of you. I love books, and I handle them carefully.
But new books have no soul, there is a unique feeling when you have an old book that you know have been in the hands of someone else. The smell, the look of old paper... Sometimes there are notes in the margin, names under the cover, etc.
I have such a book, "Towers, Turrets and Temples". Under the cover there is a mention that it was given as a christmas gift in December 1900...

A punch card is much easier to read. You can read it and decode it yourself, without any hardware.
And if you're too lazy, you can make a punchcard reader with lego.
Try that with CD's!

The answer is right here:
Is the sound on vinyl records better than on CDs or DVDs?

Very interresting stuff about human hearing.

I've been using this for years now, and I like my submenus to appear instantly.
But, it doesn't work in Microsoft applications! In Office 97, the submenus are still appearing after a delay.
Like always, Microsoft doesn't even follow it's own guidelines and their applications are always a little different than others.
we can build a positronic brain!
Have you tried putting it in the dryer? Then nobody could steal it!

I'm not against keeping an eye on religions. They are the biggest source of conflicts in the history of man.
The problem is that not every religion will be treated equaly... Bush will surely not mess with his friends of the christian right...
but it will cost a lot more...

Using data from the user input is not very usefull if your machine is a dedicated encryption server wich nobody even touches for months...

I also made a very bad rocket when I was young. The nosecone was glued in place, but I was smart enough to provide a side door for the parachute...
But, I only had a C power thing to put into that big (2 feets) rocket.
At the moment the rocket began to lift off, I knew there was something wrong, rockets are not supposed to accelerate this slow...
The rocket went slowly about 50 feet in the air, then it began to arc and was now heading for the earth, toward my neighbour's house.
Then the thrust endend (thankfully!), and the rocket dropped like a stone. The second charge blew up a part of it, and it catched fire.
I think that's why I don't work at NASA now...
But it was fun!!!

It seems to me that the author of this review is right about this, the lack of a FireWire port is quite lame.
Moving 10Gb thru USB at 12Mbit/s or LAN at 10Mbit/s takes a loooooong time indeed!
