If the areal density increases uniformly in both directions, then you can expect that the read/write speed goes up by the square root of the areal density increase. That is, for 43.75 you'd expect a speed increase of at least between 6 and 7 times. Note that sometimes the density increase is achieved in only one direction or the other, depending on what technology was used to achieve it, in which case all or none of the density increase results in speed increase.
You can achieve speed increases by using multiple heads. LTO and the 3590/3592 proprietary tape technology on which it is based use 8 or 16 tracks read/written simultaneously, with tracks interleaved. There might be 256 tracks with tracks 1, 17, 33,..., 241 being accessed, then 2, 18,..., 242. etc. Doubling the number of tracks (density increase of 2 widthwise) wouldn't increase read/write speed. Doubling the number of tracks while simultaneously doubling the number of heads would.
Note that with 8 or 16 heads spread across the tape width, error correction is achieved by writing a matrix of bits (across the tape as well as down the length) with ECC bits added.
1.6 million processors in 96 racks is 16000 processors per rack, or about 400 processors per U. To me that sounds like an evolution of the cell processor and 1 MB per cell sounds reasonable.
However, registration *is* required before filing a lawsuit.
I thought it was only required in order to have a certain type of damages awarded (which may make it economically infeasible to sue without have filed, but strictly speaking not necessary).
The article linked in the text Microsoft has begun flooding media outlets with information advising users to switch to an alternate browser while quotes a Trend Micro spokesman advising users to switch and a Microsoft spokesman explicitly saying he can't advise users to switch over one flaw. This contradicts the summary text.
I've lurked on their mailing list and I have to say I'm really impressed by the maturity of the group of developers that participate. What is really amazing is watching a new developer join and then be gently introduced into the culture of the list. That culture is polite, inclusive an respectful.
Most people soon learn the culture and participate, and the few that don't soon leave on their own accord. I think everyone who stays enjoys developing in that culture.
s there some particular reason you need to replace Outlook for an Open Source alternative? This makes no sense to dump something that works and is clearly the best solution right now.
Up until a few years ago, I would have agreed it was the best solution for most businesses, but times have changed. I don't know what industry you're in, but a lot of larger companies are introducing more Linux and Macs on their networks and the ability to function cross-platform and across a variety of clients is a huge feature for a lot of companies.
Unless you just want to save a couple of bucks, there's nothing magical about an Open Source product that makes it better.
According to MS, in order to license the current version of exchange it will cost you $4000 per server + $97 per user + some unnamed fee if you want to interconnect with other companies servers. So, assuming you have 1000 people and two servers, you're looking at over $100K. And for that price you can only use all the functionality if all your clients are on Windows, so your advertising people on Macs and your software development team on Linux both end up running their own little calendaring servers or using a shitty Web interface that has not kept up with the regular client. People with smartphones also end up costing you extra for connectors that allow them to access some of the functionality of your Exchange server, instead of all the functionality of a CalDav server.
To summarize, the failures of Exchange are:
licensing costs
future licensing costs for upgrades to support new clients
lousy cross platform support
added expense to support smartphones
lack of choice for clients
lack of choice for server platform (only Windows and VMWare) Whereas CalDav servers like Zimbra also support OS X, Linux, Solaris, etc.
lack of choice for support and customization and services, only MS instead of RedHat, Zimbra Inc, IBM, etc. (If MS does not fix a security hole tht is a problem for you, you're screwed, whereas with CalDav you can hire someone else to fix it or even fix it using internal programming resources)
...there's nothing magical about an Open Source product that makes it better.
Umm, not magical, but being OSS is a feature, one that Exchange is lacking. It is not the only feature that matters, but it does bring significant benefits, including reduced risk and protection from vendor lock-in.
To summarize, the failures of Exchange are:...
You missed one of the biggest failings. Outlook/Exchange puts the brains in Outlook and the storage and message passing in Exchange. This is not a problem by itself, but couple that with the fact that the OS platform for Outlook is Windows, where date and time are kept in local time, results in horrible problems when things like DST start/end dates change. North America got a rare taste of that this year, but some places, like Brazil, seem to choose there DST start dates weeks before the date, not years! It causes all sorts of problem because Outlook tries to compensate for multiple time zones but then you get multiple instances of Outlook (sender, receiver) doing that with potentially different views on local time in each others location. All hell breaks loose.
Given that the whole point of the Calendar feature is to deal with time and schedules, that is a damning failure.
The power is fully legal. Therefore the ramifications of using the power are purely political. He just needs to weigh the political cost. At such a low approval rate, the cost is probably discounted.
Yes, but they are not saying Gonzales should resign because he acted politically. He lied about it. Further, a political act such as the firings can result in political consequences, and in this case the gross nature of the politics of the firings results in political calls for his resignation.
There's this wormhole theory that says all data you send in/dev/null will not be lost, but actually show up on a server in an alternate universe. So no all hope is lost!
Not just on another server, but out that server's/dev/urandom. That universe's physical law's are such that their notion of random data is different from ours.
IBM Global Services isn't just essentially PwC. Before they bought PwC there was IBM Global Services which was formerly ISM (Information Systems Management?). Back then it was mostly IT outsourcing. With the purchase of PwC it grew to be business consulting too.
The article says that they have the "unique ID" of my home network. This really disturbs me because, as I'm sure most of the rest of you have done, I have configured my network to prevent this. I run a Cisco aironet 1200 AP with 802.11i, AES encryption, as the only supported method, and my SSID is nondiscoverable until you've progressed through the encryption handshake. What is this "unique id" they managed to snarf? How did they break AES 256?
For how long have we been hearing that the lack of Exchange connectivity is what's preventing Linux adoption on the desktop?
What's really ironic is that Outlook/Exchange is the most successful and only truly ubiquitous deployment of a DCE application worldwide, DCE being a creation of UNIX vendors.
I can't tell you how long I've been looking for a wireless extension cord.
Actually it would be possible (I think) to create an unpowered resonant coupler that would extend the field (there would be some loss).

Did you just tell a story about a person mixing up "rapping" for "raping" and in the process use the word "allowed" instead of "aloud"?
So if I look at the pictures in the book long enough will the alt text pop up?
Yes.
Can you imagine when they develop the ability for the computer to read sign language? I bet an adept person can sign faster than most people can type.
Yes but that last 32k is the EVIL 32k
You mean each of the evil bits left over from the 129 MB of data?

So it's not just vaporware, it's an "umbrella concept" that will be built into future products.
In other words, it's plasmaware!

Not just on another server, but out that server's
The first 14 characters are still used in Lanmanager hashes though, so this is only a security hole if the attacker can access the hashes.
And don't the hashes fly across the network in the clear (unless you are using Kerberos in a non-compatibility mode?)?

They are in the business of selling eyeballs, not search results or email services or... The latter are simply the costs of acquiring eyeballs.
