Tape!?! :confused: who on earth uses tape anymore? This is.. 2006. And I was always under the impression that a medium with moving parts would be more prone to failure than one without. Certainly my VHS and cassette library have had their share of tapes being chewed up by the machine or worn out from use.
Tape is still the most reliable, long-term archival media available. Newer tape systems can transfer over 150MB/sec. to and from the tape and store several hundred GB on a single tape. Cost-wise, tape is expensive to buy into, but if you have sufficeint archival needs, it pays for itself over time. Many tape solutions once they reach their ROI point afer a year or two, often are cheaper than HDD storage by half or more. Sounds weird, I know, but that's the way it still is.
Most large data centers covering everything from web storage, insurance databases, financial institutions etc... Have mostly converted over to large-scale redundant servers and storage networks using RAID subsystems. This serves all their immediate storage and backup needs on site and is very reliable if managed properly. But nearly all of them still use an additional tape archival workflow for off-site data storage. There really is no other way right now... Wish there was. Hence the reason tape systems also keep evolving and pretty much match HDD capacity with tape capacity in most cases and transfer rates continue to improve. Comparing tape archival systems to VHS or miniDV tape is not a good comparison, data tapes (or at least the good ones) are very robust and actually very hard to damage. Short of placing them in a magnetic field for a period of time, they're mostly indestructable. They do have moving parts, but hardly any compared to a hard drive.
Using hard drives as an archival solution is a bad idea... Hard drives are not designed for this and can corrupt data over time. Not to mention, the platter system and motors are not designed to sit stationary for years at a time for long-term storage. Optical media isn't too bad, but most photo-sensitive dyes and films used in optical media will decay over time. CD-R media was originally claimed to have a lifespan of 30 to 100 years. Now that it's been around for 30+ years, we're finding out that claim was somewhat exaggerated. Recordable DVD media and HD-DVD and BD are no different, just higher data density on the discs. And also not anywhere near practical for large-scale solutions. Just how do you archive and manage 300 petabytes per year to DVD-R???
For small business type users and home users though, DVD-R media in addition to a good redundant RAID setup probably makes the most sense. Unless they're pushing lots of data doing HD video editing or something like that. In which case, it may still make sense to give tape a consideration as the long-term archive solution. Prosumer level tape archive systems exist and are not that expensive and much more reliable than shelved hard drives and much easier to manage than optical media. The VXA2 format can afford someone an external Firewire tape system w/2 tapes for < $1K. Tapes hold up to 160GB each and factoring in the cost of the drive plus enough tapes to back up about 3 terrabytes of data, the cost becomes cheaper than individual hard drives. So a few terrabytes down the road and you could be wishing you had considered tape if you're still using DVD-R. OTOH, DVD-R is just fine and dandy if a terrabyte or two is all you need. Because you can fit a lot of discs in a shoebox and sharpie pen to label them is pretty cheap too.
External drives are *not* long term archiving solutions. They are useful for storing vast amounts of data that presumably you want to actually access and use (and possibly modify) on a regular basis; also, they are good for the kind of incremental backups you refer to, Time Machine, Retrospect, other 3rd party backup tools can be used for this. But if you have important files you know aren't going to change, while having them on HDD is useful for instant access, that's not where they should be permanently archived -- they should be burned to a permanent medium, preferably more than one copy, and stored in a safe place (or places). If your drive fails and you still need the data to be on that drive, you can then restore from the permanent medium.
Um... I guess I got carried away and didn't mean to elaborate on what you already said. But, er... um.. Yep, I agree.

Could someone please tell me what is thanksgiving, I have seen it being celebrated on many american television programs and I know it's got something to do with turkeys but they never seem to mention its origins. Also is it a national public holiday ?

That was painful to watch. Sort of like Jack Ass: The Geek Edition. Of course they should be banned. Gizmodo was interfering with companies trying to present their products.
...which is absolutely fine. In fact it is a form of standing up for corporations, YES.
Pathetic attempt? Probably, yes, I think so too and also silly but it's still way less disgusting than these ridiculous brainwashed comments here, this incredible hypocrisy people showcase here when it comes to corporations or Apple or anything.
For God's sake the person who was in charge for the presentation should be fired on the spot. Yes, it's that person, his incompetence that allowed this prank.
Man, I never visited Gizmodo regularly but thanks for showing me this piece - I will put them into my Google start page. Not because it's funny - it isn't, it's kinda pathetic - but because apparently they have the guts to do things.
Thanks for the info, again.

This house can be yours too for the low price of 399,999.99 (or 349,999.99 with a 10-year contract.). Of course, version 2.0 will be out in 12 months that makes this house obsolete.

Oh i'm sure there will be LOTS of technology in the house.
I bet he'll be able to control everything via an app on his iPhone.
The house itself doesn't need to be HUGE. He can still apply a lot of technology into the house making it worth millions!

Most Americans do not have what you do. And to the person who said I've never experienced "4 screaming kids," I have.
I think you both are just use to having more, and space, and more space. My grandmother raised her six children in a three bedroom, one bath home � that she shared with my grandfather � and never had any issues. My grandparents, mother or my aunts never complained, and looking back, I think the experience enriched them tenfold. My grandparents were successful and could have afforded a home with "enough space" (by your standards) for all their kids, but they made out just fine in the first floor of an apartment building with "just" 2,200sq. feet.
Used to having more? No. I am one of eight kids and my wife is one of ten. We both grew up in modest houses. Mine was 4 bedrooms 2 baths, same as hers. It did not enrich my life. My sister and I never got along because of tight quarters, and after we moved out our relationship remained tense. We finally started getting along just before she died. My house now is 4 bedrooms 2 baths, one of which is converted to an office. My sons and daughters share their rooms. But, given another chance (we bought the house before our first, who would have thought there'd be 3 more) we would have made a home elsewhere. Now that this is home, it's hard to leave.
Don't presume to know my "standards". We have enough space, but doing it all over I'd choose more. I work hard. I make money accordingly. What's money for if not improving the lives of my family? I don't want a big house for no purpose, I'd just like enough to give my children some personal space so they don't have to collide every day.

This is utter ********. The experience is key, and LTE hardware is nowhere near advanced enough to guarantee the experience that Apple would demand for a device the stature of the iPhone.
Remember: we're talking about the company that withheld phone wallpapers on the Original and 3G iPhones because the experience would have been several milliseconds too slow.
Fact: Verizon is not expecting LTE-capable hardware until mid-2011. There's no way Apple magically has an LTE phone ready to go while everyone else won't have one for 6 months.
Fact: Apple declined to integrate 3G into the iPhone when 3G was already available, because the hardware wasn't power-efficent enough. One of the main distinguishing features of the iPhone is its battery life. They're not going to tarnish that image by hacking first-generation, power-hogging LTE hardware into the phone, in ADDITION to CDMA, which is another radio tech they're only now deploying.
These sources are full of ****. QED.

Guns are within my scope of practice (http://www.sfgate.com/cgi-bin/blogs/rchoi/detail?entry_id=88328)
Couple this with the fact that the NRA has prevented any studies on guns and their impact on American society and I think we can all rest assured that we're heading towards a society ruled by the American Taliban. Heavy sarcasm intended.
If guns are so important to society, why is it taboo to have an adult conversation about their impact on that society?
Why? In the mind of the NRA:
Step 1: Talk about guns.
Step 10: Ban and confiscate guns.
Therefore they resist even common sense initiatives supported by police such as gun fingerprinting.

The TV Shows section started out with 5 shows (zero here) and now look at it, there are hundreds of TV Shows for download on iTunes (zero here).
It just takes a few to get it going and once some momentum is established it just keeps picking up speed.

I hope that we'll all be pleased with the improved DB code for searching, keywords, etc. It always seemed to me that THIS was the major failure of Aperture. It's RAW onscreen conversions were never bad in terms of speed, given the amount of processing that was going on. But the old DB searchs of 15 seconds (with NO conversions!) always implied poorly written code/bad code design.
With 1.5 and the expanding list of supported computers, it appears that the Aperture team finally cleaned up this mess. Hopefully the result will be a pleasant surprise for all.
Here's my earlier post where I talked more about keyword imprivements, esp the new "no" keyword option which was MY major gripe for such a minor issue:

Right, a product in development since 2002 (http://photoshopnews.com/2006/01/09/the-shadowlandlightroom-development-story/) was a copy of a product released in 2005 :rolleyes: :rolleyes: :rolleyes:
Do you really believe Lightroom has been in active development since 2002? I'm thinking it was a proof of concept in 2002.
I mean, if it's really been in development since why isn't it finished yet? Why is it so far behind Aperture?
That claim by Adobe is just ludicrous.

for a single phone to sell 4million, i think thats amazing!
rim only has 20% more smartphone holding and think of all the versions that it has and how many years has the blackberry been around? atleast 5, problaby way more then that.
yes, 5 million were expected, so without saying it outright, steve admits the iphone has not performed as expected.
note also his omission of the two biggest iphone news items: the price drop shortly after release, and the big "F.U." and subsequent backtrack concerning unlocking the phones.
of course, he's within his right to try and accentuate the positive...:apple:

Agreed. Sadly, I was working on an App nearly IDENTICAL to what Apple just came out with. I am about 80% done but am wondering if it is even worth completing: http://computerharmonyinc.com/ibillboard.html
Been tried, been rejected.
Nice try though. An app where you make money every time someone taps the screen - you must have been wetting yourself with excitement.

I really can't see Apple removing the usage for 'pro' users. They're just making it more welcoming for the millions who are now in the Apple ecosystem through iOS devices.
My understanding is that unlike Windows, Apple offers one (or two if server edition) version of the OS, be the most experienced pro or the new comer you use the same system.
I would expect Apple to make the Mac OS to be far more like iOS in that you do what you see, so the new comer isn't faced with libraries etc; however, somewhere in the system there will be options to view and access the deeper lying elements of the OS that the average user won't need to ever see.
