I don't know if that last bit was a troll or not, if so you got some of us. Adobe will continue to make Mac programs for a long time. They are only dropping support for Premiere, because other products have taken over the high end and iMovie has taken over the low end of the video editing market. Hardly anybody uses Premiere anymore on a Mac.

What happened to the neighbors? They all die of cancer?
They are basically anti-fruad messages saying that those fraud alert emails are not from Best Buy, they are investigating them with law enforcement officials, reiterating that their online store is safe, etc.

The Next Step in the Spam Control War: Greylisting By Evan Harris Copyright 2003, all rights reserved.
Introduction This paper proposes a new and currently very effective method of enhancing the abilities of mail systems to limit the amount of spam that they recieve and deliver to their users. For the purposes of this paper, we will call this new method "Greylisting". The reason for choosing this name should become obvious as we progress.
Greylisting has been designed from the start to satisfy certain criteria:
1. Have minimal impact on users
2. Limit spammers ability to circumvent the blocking
3. Require minimal maintenance at both the user and administrator level
User-level spam blocking, while somewhat effective has a few key drawbacks that make its use in the continuing spam war undesirable. A few of these are:
1. It provides no notice to the senders of legitimate email that is falsely identified as spam.
2. It places most of the costs of processing the spam on the receivers side rather than the spammers side.
3. It provides no real disincentive to spammers to stop wasting our time and resources.
As a result, Greylisting is designed to be implemented at the MTA level, where we can cause the spammers the most amount of grief.
For the purposes of evaluating and testing Greylisting, an example implementation has been written of a filter that runs at the MTA (Message Transfer Agent) level. The source for this example implementation is available as a link below, and as other implementations or additional utility code become available, they will also be linked.
Greylisting has been tested on a few small scale mail hosts (less than 100 users, though with a fairly diverse set of senders from all over the world, and volumes over 10,000 email attempts a day), however it is designed to be scalable, as well as low impact to both administrators and users, and should be acceptable for use on a wide range of systems, including those of very large scale. Of course, performance issues are very dependent on implementation details.
The Greylisting method proposed in this paper is a complimentary method to other existing and yet-to-be-designed spam control systems, and is not intended as a replacement for those other methods. In fact, it is expected that spammers will eventually try to minimise the effectiveness of this method of blocking, and Greylisting is designed to limit options available to the spammer when attempting to do so.
The great thing about Greylisting is that the only methods of circumventing it will only make other spam control techniques just that much more effective (primarily DNS and other methods of blacklisting based on IP address) even after this adaptation by the spammers has occurred.
The Greylisting Method High Level Overview Greylisting got it's name because it is kind of a cross between black- and white-listing, with mostly automatic maintenance. A key element of the Greylisting method is this automatic maintenance.
The Greylisting method is very simple. It only looks at three pieces of information (which we will refer to as a "triplet" from now on) about any particular mail delivery attempt:
1. The IP address of the host attempting the delivery
2. The envelope sender address
3. The envelope recipient address
From this, we now have a unique triplet for identifying a mail "relationship". With this data, we simply follow a basic rule, which is:
If we have never seen this triplet before, then refuse this delivery and any others that may come within a certain period of time with a temporary failure.
Since SMTP is considered an unreliable transport, the possibility of temporary failures is built into the core spec (see RFC 821). As such, any well behaved message transfer agent (MTA) should attempt retries if given an appropriate temporary failure code for a delivery attempt (see below for discussion of issues co
If the steering wheel is pointing to the right, focus the radar to the right as that's where the collision would most likely happen
In my scenario, when the road curves ahead of you, there is a time when your steering wheel is pointed at oncoming traffic. Thus you would come to a sudden stop when in fact, you shouldn't.
Let's say you're on a 6-lane highway. All three lanes in your direction have cars ahead. You turn this thing on, and it follows the car in front of you.
Now the highway turns sharply to the right. Suddenly oncoming traffic is directly in front of you. How does it know which car to "follow", i.e. keep a safe distance from? If it makes a mistake, thinking you need to keep a safe distance from oncoming cars, when you go around the bend it'll slam on the brakes and you'll get rear-ended (unless of course the person behind you also has this system, in which case he'd stop too. In fact all cars would stop at every sharp turn).
Even if the system somehow knows exactly how much the road curves in front of you (which I doubt unless the road has transmitters or other indicators), it would be very hard to maintain a lock on the same car. Police radar cannot distinguish between two cars that are one behind the other. And if it doesn't track a specific car, how can it tell the difference between an oncoming car and a car ahead slamming on the brakes?
If you only have 3 gb of data, a 3gb hard drive will be somewhat slower than 10 gb of the same rpm, cache size, etc. in general use, due mainly to seek time. On the 10gb, the data will be spread around the drive, so when it wants to write, it will only have to go a little way to find an empty spot. The 3gb will have to jump all over the place to find empty spots, and likely fragment data more. Makes sense right?
No, that makes no sense at all. You are comparing a fragmented drive with an unfragmented drive. Did it ever occur to you that a 10gb drive can be fragmented too?
The reviewer tested new, out of the box PCs. You can assume the 3GB drive was not yet fragmented. The slowness was due to the fact that it was a notebook drive, which typically have lower RPMs.
And, when we sold an OEM copy of Windows, we included the $1 hard disk or motherboard!
I noticed that TigerDirect includes some sort of floppy adapter cable with their OEM copy of Windows.

There are no good ways to create one in any language. Current solutions are either:
(1) A thin shell over text and graphics primitives
or (2) dependent on an external rendering engine which creates another format like Postscript.
I'd like a high-level PDF creation library that would let me, say, directly create a table that is sized to fit the contents like HTML, but unlike HTML, will split the table across multiple pages, repeating header and footer information.

This time, SFgate is wrong. It's not a hoax. Read the article. It's a legitimate experiment to build a prototype for the Glastonbury festival.

The students? None. Apple's the one wasting the money here.
If they had given the iPods to an Embedded Systems class at MIT, and challenged them to find "creative uses" for them, I'm sure we'd see a lot of newsworthy (at least Slashdot-worthy) things. But I doubt this class will find "uses" that we'd give a hoot about.
