I only used the term imaginary as a sort of insult to digital

a CD player).


This is a red herring, unless you actually plan to spin records  
yourself and drop a pine needle + styrofoam cup into the groove.  In  
real life, you're using an electronic playing machine, and if it  
breaks, then your music too is imaginary until you fix or replace it,  
so you're no better off than with CDs.  On the contrary:  CDs are  
smaller, hold more content at higher resolution, can automatically  
seek to track boundaries (or arbitrary locations), can pause reliably,  
may contain additional non-audio content, are more durable, and can be  
losslessly copied, either disc-to-disc or via rip and burn (if you  
avoid lossy compression like MP3, of course).


There is a big difference between analog and digital technologies.  
Both vinyl records and compact disc do use plastic circles with  
information stored on the surface, but analog information doesn't  
need to be decoded like digital does. The very minimum you need to  
play back a CD is a CD player, with complex mechanics and computer  
chips, while you can play a record with nothing more than a paper  
cone and a spinning surface that can be moved by hand. Sure, it  
won't sound nearly as good as playing the record on a stereo, but  
you can still retrieve the data with almost no technology  
whatsoever. This is because the scratches on the disc are an imprint  
of the actual sound wave, and while they may be recorded and read  
electrically (or in the case of some releases since the 1970s, even  
mastered digitally), the only real process that goes into recording  
and playing most records is electrical amplification and  
manipulation. With a CD or any other digital recording, you only get  
complex instructions on how to reproduce the file.


Perhaps the simplest way to examine the differences would be to  
compare the most primitive versions of analog and digital  
recordings, player piano rolls and wax cylinders. The wax cylinder  
can reproduce the sound of a full orchestra with nothing more than a  
motor, lathe, needle, and horn, while the piano roll needs an actual  
piano and is incapable of performing other voices or even simple  
stylistic accents like volume and intensity. Both technologies have  
come a very long way, but there still remains the fact that an  
analog recording contains an imprint of an actual sound wave while  
digital recordings are instructions that tell the computer how to go  
about reconstructing the sound.


Audio CD contents are data, not instructions.  The data are just as  
much a waveform as are the scratches on a vinyl record or wax cylinder.


By the way, have you actually *heard* a wax cylinder?  Listen to this  
1910 recording of the Major General's song by C. H. Workman, or the  
1888 recording of Sir Arthur Sullivan addressing Thomas Edison.  The  
song is enjoyable despite the heavy scratching distortion, but perhaps  
more as a historical record than for its entertainment value -- in the  
same way that you might place an ancient pot on display in a museum  
for viewers to appreciate, though you're not going to cook in it.


The speech however, is barely discernible and considerably less  
pleasant to listen to.  Maybe encoding the sound wave directly onto a  
physical medium is not the best way to go.  Or maybe it just  
deteriorates over time, which would be another great reason to avoid it.

Now rather than actually trying to compose a shot and take one good  
picture, people have become accustomed to pointing the camera in the  
general direction and clicking the shutter as many times as it takes  
before they accidentally get a good picture.


Computer-assisted photography is related to but distinct from the  
issue of analog vs. digital storage.


Storage can be another problem, because while physical photos do  
take up room, digital pictures take up a lot of storage as well, and  
a shoebox is quite a bit cheaper than a new hard drive.


One hard drive (which I needed anyway to use the computer at all) is  
enough to store every photo I've ever taken at a resolution  
appropriate to the camera I used.  One hard drive is smaller than many  
shoeboxes.


In the end, most people switch to digital and never look back or  
care about the problems, but I want a physical master and total  
control of the picture, so I'm sticking with film until no one makes  
it anymore.



I'd rather have the ability to make lossless backups of my photos than  
be stuck with having to guard the unique master copy.

I agree that USB is slower than Firewire, but the lag you experienced

The Intel iMac we're talking about has USB 2.0 ports, so he won't have

External USB DVD devices are cheaper and easier to get than Firewire

That really annoys me, since I don't consider digital files to be actual 
things, just imaginary concepts. Sure I can listen to them, but in reality they 
are just magnetic states on a disc which, when read by a computer, give 
instructions on how to synthesize the music in question. I buy most of my music 
on vinyl, where I get a disc with an actual sound wave encoded on it, or reel 
to reel tape, where I get a magnetic wave that is an electronic implementation 
of the original sound wave (I don't even use digital cameras because there is 
no master negative, just a digital copy). Even on Compact Disc you get a much 
denser and more accurate synthesis on a physical medium. But I put up with 
digital music because it is so convenient. I can't go around with a record 
player, and even when the new Crosley Revolution comes out I won't be able to 
use it everywhere I can use an iPod, so I do have a large iTunes library, but 
when I get home I always listen to records and tapes.

Movies are a different story entirely. All I need to do to listen to an MP3 
anywhere is put on headphones. Sure, some may complain that you can't play MP3s 
on a home stereo, but quite frankly I don't want to play MP3s on my hi-fi 
because then I could hear how bad they really are. With digital movies, on the 
other hand, the only way I can watch them on anything other than my computer is 
to use my video goggles (MyVu), and since I wear glasses I don't like to use 
those anywhere except planes and a few other situations where I wouldn't want 
to hold up an iPod for a long time. There is no way to watch them on a TV short 
of pulling it out from the wall and plugging cables in, and even to watch them 
on another computer you need to somehow transfer the file first. And even if 
you do have a fully wired house with a high speed home network and an TV, 
there is the problem of quality. Just like with MP3, there is a reason that an 
HD movie on iTunes is about 1-2gb while a Blu-Ray can be up to 50gb. While most 
people never notice the low quality of MP3 because of the cheap iPod headphones 
or constant background noise when listening to music, video compression is much 
more apparent, especially with fast moving action scenes.

Add to this outrageous prices comparable to infinitely superior physical 
copies, and it is easy to see that Steve Jobs' dream of killing physical media 
with low quality downloads is certainly not going to happen any time soon. The 
key to success on the iTunes store was low price point; while complete albums 
don't cost much less than actual CDs, most people only buy the CD for one or 
two hit songs, and in that case 99¢ is a much better price than $15. Now when 
you can pay $10 for a standard definition video or $15 for a DVD (complete with 
special features and a digital copy) that you can own, play on any TV or 
computer, and even sell later, it is not nearly as enticing to buy online. And 
considering that Blu-Ray hasn't really managed to make a dent outside of home 
theaters, in which case the people watching demand the highest quality possible 
and don't even consider downloads to be a real option, Apple really doesn't 
have any reason to believe that they will be able to singlehandedly kill the 
optical disc. And Apple's current stance would be yet another reason to get an 
external BD-ROM drive, since even the high end computer two years down the line 
might not have a Blu-Ray drive.

I can understand, however, how some people will want instant gratification and 
won't care about quality or convenience. This is all coming from someone who 
insist on LaserDisc for standard definition (same resolution as DVD, but with 
uncompressed analog video), and 16mm for high definition (much higher 
resolution for good prints, no possibility of compression, and pure unmatched 
color in the case of Kodachrome and Technicolor, although I do have to put up 
with low fidelity monophonic sound) even though they are much harder to find 
and in the case of 16mm several times more expensive than even Blu-Ray (which 
is why the only feature I have on 16mm is a silent print of Charlie Chaplin's 
Modern Times), so I'm certainly not the average person when it comes to video 
preferences. From what I have seen and heard, though, most people at least seem 
to agree with me on digital downloads being inferior and much less convenient.

Wow, that sure turned into a rant. By the way, sorry about that blank message I

Well, that was a very specific piece of advice. I personally favor
Firewire for all the abovementioned reasons, and when the first

because no FW transfer speeds and no target disk mode was a

 They may be not immediately tangible, but you can, with the aid of an 
 electron microscope, visualize a file on a hard disk platter; digital files

I only used the term imaginary as a sort of insult to digital files. Yes, 
they may technically exist, but only in the same way that a song on the radio 
exists, not in an immediately available physical form (I can't very well remove 
my hard disk and play it in a CD player).

 Wow, that's an impressive display of cognitive dissonance. 
 
 In reality a vinyl record is just a piece of plastic with some scratches on 
 it that your record player decodes into sounds, just as a computer decodes a 
 MP3 file. With tapes it's even more like digital because you're literally 
 flipping bits of iron oxide in the tape.
 
 True it's an analog encoding rather than a digital one, but it's still a 
 non-aural, lossy encoding of a sound. Try as you might, without the aid of a 
 decoding device, a vinyl record, a reel-to-reel tape or a CD loaded with MP3 
 files equally make no sound whatsoever.

There is a big difference between analog and digital technologies. Both vinyl 
records and compact disc do use plastic circles with information stored on the 
surface, but analog information doesn't need to be decoded like digital does. 
The very minimum you need to play back a CD is a CD player, with complex 
mechanics and computer chips, while you can play a record with nothing more 
than a paper cone and a spinning surface that can be moved by hand. Sure, it 
won't sound nearly as good as playing the record on a stereo, but you can still 
retrieve the data with almost no technology whatsoever. This is because the 
scratches on the disc are an imprint of the actual sound wave, and while they 
may be recorded and read electrically (or in the case of some releases since 
the 1970s, even mastered digitally), the only real process that goes into 
recording and playing most records is electrical amplification and 
manipulation. With a CD or any other digital recording, you only get complex 
instructions on how to reproduce the file.

Perhaps the simplest way to examine the differences would be to compare the 
most primitive versions of analog and digital recordings, player piano rolls 
and wax cylinders. The wax cylinder can reproduce the sound of a full orchestra 
with nothing more than a motor, lathe, needle, and horn, while the piano roll 
needs an actual piano and is incapable of performing other voices or even 
simple stylistic accents like volume and intensity. Both technologies have come 
a very long way, but there still remains the fact that an analog recording 
contains an imprint of an actual sound wave while digital recordings are 
instructions that tell the computer how to go about reconstructing the sound.

 In reality the advent of digital photography has ushered in a true golden age 
 of photography...you get feedback *instantly* on whether your photo was 
 properly framed, exposed, focussed, etc...that instant feedback, coupled with 
 the virtual zero cost of digital photos has let people get the amount of 
 practice they needed to become better photographers.

While that may be true in theory, the reality is very different. Rather than 
help them learn how to properly compose a shot by giving them feedback, digital 
cameras actually severely limit the abilities of the average user. Now rather 
than actually trying to compose a shot and take one good picture, people have 
become accustomed to pointing the camera in the general direction and clicking 
the shutter as many times as it takes before they accidentally get a good 
picture. While people used to come back from vacation with a few rolls of well 
composed pictures, now they have several thousand pictures that they will need 
to sift through to find a handful of good ones. This is of course generalizing, 
as there were many people in the time before digital who never bothered to 
learn how to take a good picture and there are many today who do use the 
advantages you mentioned, but overall knowledge about how to properly use a 
camera have fallen drastically. Even some professionals who use high end 
DSLRs don't have any idea what ƒ-stop and shutter speed mean, because the 
camera does all the work for them. Storage can be another problem, because 
while physical photos do take up room, digital pictures take up a lot of 
storage as well, and a shoebox is quite a bit cheaper than a new hard drive. In 
the end, most people switch to digital and never look back or care about the 
problems, but I want a physical master and total control of the picture, so I'm 
sticking with film until no one makes it anymore.

The issue I have with digital files is that regardless of the media you 
store them on, be it a HDD or flash drive, both of which are subject to 
magnetic damage; or writable optical media, which seem to degrade simply 
by existing; they are subject to deterioration over time. A bit gets 
flipped here and there eventually resulting in discernible damage to the 
file. Enough bits get flipped and the file becomes useless.


In nine years of computing I've had several files, mostly text and image 
files, that have mysteriously become unreadable. Given time it's likely 
that I will encounter a video file that has become corrupt and is no 
longer usable. If I originally purchased the data on a pressed, not 
burned, optical disk I can make another copy. If I purchased the data as 
a download then I have to hope that the vendor will let me re-download 
it. However I don't trust the vendors to do what I consider to be the 
right thing and pass on a perceived opportunity to make additional profit.


That is why I prefer pressed CDs and DVDs. Yes they are subject to 
damage but they don't spontaneously degrade, at least they shouldn't in 
my lifetime.


Sorry Steve (Jobs), I think you are wrong.

Dear Penguirl:
 
They no longer Burn CDs or DVD's on computer  media for the home.  It 
the old days, the original burners actually  burned a small section of 
the CD/DVD and the mark was permanent.  Either  the section had a small hole 
burned in it or it didn't.  Newer CD/DVD  burners now make a mark in dye on 
the CD/DVD R, RW.  The dye deteriorates  after about three to five years so 
the CD/DVD then no longer has any information  on it, things have become 
unreadable.  If you can find an old burner, I  mean from the 1990's or before, 
or buy a commercial grade burner, then the  medium will actually be burned 
in actuality, and the image should be  permanent.  I have a couple of old 
burners and they actually do the job by  burning the image into the disk.  
Even so, you have to watch for spelling  and other mistakes that may creep in 
as the original gets older.  Magnetic  media is safer than newer CD/DVD media 
for securing the information you want to  keep.  Thumb Drives, also called 
Jump Drives and other magnetic media  really hold onto the information a lot 
more permanently than the new CD/DVD  technology.  The only other thing you 
can do to insure your  information is safely saved is to print it all up, 
and keep it in a fireproof  safe.  I would love to hear more on this subject, 
I want to hear about this  subject.  Thank you, sincerely, Virgil Fritz.

Kevin,

This is the first generation Core 2 Duo iMac. I have the 17 model.
They are great machines. They are prone to display/video card
problems, which apparently has been silently acknowledged by Apple,
since mine broke last year and was repaired for free by them (that was
before I got it but the previous owner gave me the paperwork).

That said, it's anyway a great machine, it's at a great price, and
chances are it'll never give you a headache. So I'd say go for it.

I have a late 2006 24-inch iMac (white, Core 2 Duo).  The graphics

far, only when I hit trigger Exposé by accident).


The hard drive died shortly after AppleCare ended, and the optical  
drive died some time after that.


It seems Apple uses shoddy components to lower the up-front cost,  
while raising the total cost of ownership.


Should I pay the Apple Store to replace the dead optical drive with  
the same model, pay a third party to install a better device, buy an

I'd go with the external. USB DVD devices can be got for less than $40

My third generation iPod was more like a 5 month shelf life, but that was 
mainly because I kept it in the pocket of a baggy coat and regularly 
(accidentally, of course) slammed it in the car door (which is in turn why I 
had to replace the hard drive). I learned my lesson, though, and three years 
later when I got my iPod Classic I treated it very well. I got it the day after 
the Classic was announced in September 2007, and more than three years later it 
hasn't given me a single problem (apart from a corrupt drive directory, which 
DiskWarrior easily fixed). If you treat an iPod like a Walkman, then sure it 
won't last very long, but as long as you treat it like a device that has 
complex computer parts, and (in the case of the iPod Classic), a hard disk 
drive, they can last for a very long time.

Re: Wondering about issues with this particular iMac

2010-09-25 Thread Steven
I'm considering getting a Blu-Ray drive when I finally get fed up with my 
SuperDrive and can afford to do something about it. The cheapest route would of 
course be an external DVD drive, but when I took my PowerBook G4 in for some 
repairs they said that they charge a standard price for repairs regardless of 
parts, something like $250-300 (which was a big plus at the time since I needed 
to replace a logic board that can cost $500+ from third parties), and I have 
seen some BD-ROM/DVD-RW/CD-RW drives compatible with Mac for around that price. 
If I were going to pay that much anyways I would want increased functionality, 
and, being the cinephile I am, eventually I will need to start upgrading my 
collection of post-2000 DVDs to Blu-Ray (all films made before 2000 I only buy 
and watch on LaserDisc) and since I don't have an HDTV and don't plan on buying 
one in the near future the Mac would be the only way to watch HD. My reasoning 
is that although I don't have any problem with the video quality of DVD and I 
don't even have a TV that could make use of the increased definition, 
eventually Blu-Ray will eclipse DVD just like DVD eclipsed VHS, and it would be 
more cost effective to switch sooner and start buying movies on Blu-Ray so I 
have fewer DVDs to replace later on. But I'm not planning on doing that very 
soon, and for people who don't have a large number of videos and don't care 
about HD that solution wouldn't make much sense.

Re: Wondering about issues with this particular iMac

2010-09-25 Thread Midnight rider
Blu ray drives aren't all that expensive if you know where to look. I picked
up myself a sweet drive back in best buy for only $170, and it is made by
HP: It has DVD reading/burning, CD Reading Burning up to 64x, DVD dual layer
burning/reading, DVD quad layer reading/burning, Lightscribe laser
engraving, and of course, Blu-Ray reading/burning. I burned a blu-ray disc
for  part of my backup volume (about 25GB out of my total 144.23GB backed up
now.) and my iMac G4 took about 3.2 hours burning it. I decided to get one
for my G5 iMac but put it through an external enclosure and through firewire
and it only took 1 hour to burn a 25GB image.

My iMac g4 takes 15-22 minutes average burning a 7GB image my G5 iMac
only takes 10-13 minutes at most, 9 minutes was the shortest ever.

Also, don't go through with USB. USB IS SLOW. it lags even on USB 3.0.
To save time, get firewire to make sure the speeds are good. I made this
mistake by buying a USB powered external DVD drive to install leopard on my
Power Mac G4 sawtooth, and installation took 5-6 hours, but IDK because the
intro video woke me up. I know that most of you think that the G4 sawtooth
is slow, but in reality even for the G4 sawtooth 5 hours is VERY slow. at
most my G4 sawtooth takes about the same amount of time as any other macs
would take to install leopard, even the intel machines which was 1.5 hours.
I later got  that blu ray drive (which is now in my iMac) and i tested it
and it only took 1.5 hours to install leopard. Basically, my advice: USB is
good for transferring small things. Anything larger than 10-20Gb should be
handled by firewire. This is just some advice from a person (me) who needs
fast transfer speeds. I have an 80GB EIDE 10,000 RPM HDD in there (it cost
me $179.99) and it has a transfer speed of about 37MB/s whenever i copy or
move something onto the same thing or anything else in the system except for
USB.

Good idea.  DVDs have noticeably chunky pixels on a 24-inch screen,  
which is just large enough (1920x1200) for Blu-ray's 1080p[1].  And  
external is a good idea so I can use it on any machine -- such as a  
new iMac, were I to buy one.


The only problem is the iMac is running Tiger, for which VLC (at  
least) has dropped support.  Perhaps it's time to install a newer OS X. 
[2]


And yeah, I have no interest in buying a TV.

Josh

[1] Assuming a 16:9 aspect ratio, this means a width of 1920 pixels.

[2] I hesitate to say 'upgrade', since I consider differently code- 
named OS X versions to be separate and incompatible products.  Hence  
'newer'.

Wondering about issues with this particular iMac

2010-09-24 Thread Kevin
I considering buying one of these model iMacs for my wife to use. She does, web 
surfing, email, iTunes and a little bit of iPhoto. I know that some of the 
iMacs around this era had a bulging/burst capacitor issue. Does anyone know if 
that was a problem with this version iMac? Are there any other gotchas about 
this model of the iMac?

Thanks,

Re: Wondering about issues with this particular iMac

2010-09-24 Thread Steven
I have this exact model (except mine only has 1gb of RAM), and it works great. 
The only problem I have had with it is that the slot loading CD drive became 
misaligned, causing the disc to jam against the inside of the case unless I 
guide it out with an index card. Judging by the reactions of the people at the 
Genius Bar, however, I don't think this is a very common problem.

No, the Capacitors of Death were pretty much confined to the G5 iMacs;  
the Core 2 Duo iMacs are two generations later. This one is a good  
machine.
