Whats the difference between sending messages via socket and MQs?

Whats the difference between sending messages via socket and MQs?With JMS (and the like) your application uses a socket to connect to a central server called a "*Message Broker*". Over this connection it can send or receive messages.
A Message Broker is somewhat analogous to a database server. Multiple clients connect to it to exchange messages. As with a database a client first establishes a connection, then requests specific facilities like subscriptions.
It creates a strong decoupling between sender and receiver and handles stuff like allowing multiple receivers for the same message, queuing of messages for applications not currently running and so on.
(And don't worry, you can get perfectly good message brokers for free such as openMQ and activeMQ.)

Whats the difference between MobileMe Mail forums 960 and 961?

There are two MobileMe Mail forums. One is under "MobileMe on www.me.com" and the other is under "MobileMe on my Mac". There isn't really a new desktop mail application is there? Or am I living in a cave, and just didn't notice the update/announcement?

Unless I'm misunderstanding what you're seeing ...
No I think you understand. It is just that I've been reading some of the posts in those forums, and it is often hard to tell what exactly people are talking about. The terminology used made me think maybe I had missed something. Maybe there was a MobileMe Mail App on my Mac, I thought that could 'sync' something.
Examples:
[Where has 'Mail Rules' gone..?|http://discussions.apple.com/message.jspa?messageID=7645781#7645781] seemed to be describing a webmail interface, but then I wasn't sure.
[Mobile me mail doesn't work at all.|http://discussions.apple.com/thread.jspa?threadID=1616729&tstart=0] mentions mail on the web, but then addresses
[Syncing Mail Folders w/ MobileMe|http://discussions.apple.com/thread.jspa?threadID=1616331&tstart=0] mentions syncing mail folders; made me think maybe there was a feature I had misunderstood.
In general, it is a little hard to tell when people are talking about the web interface or the traditional desktop Mail.app.

Confused - whats the difference between K8N Neo4 SLI Platinum and Diamond??

MSI web page says the Diamond has:
"Silicon Image's SATA RAID supports another 2 SATA II ports. Transfer rate is up to 300MB/s."
http://www.msi.com.tw/program/products/mainboard/mbd/pro_mbd_detail.php?UID=638
their Platinum page doesn't list the Silicone Image raid as a feature on the Platinum.
I have K8N Neo4/SLI Platinum and it has the Silicone Image raid - I'm using it now.
Can anyone explain this?
Another question: for both boards it shows: "NV RAID (Software) - - RAID function available for ATA133 + SATA HD drives or 2 SATA HD"
How can the Raid fuction work for ATA133 drives since the cables for SATA and PATA are different? What do the mean Raid for 133?
Thanks!!!

What are the differences between Turn in Final Timesheet and the other option: Send Progress for Selected Tasks?

Hello,
The resource filled his/her timesheet in PWA.
Now :
What are the differences between Turn in Final Timesheet
and the other option: Send Progress for Selected Tasks?
Thanks

You are partially correct and partially wrong.
Turn
in Final Timesheet sends
the timesheet to the Timesheet Manager for Approval
but task update always goes to Status manger of the task. Taks manager you can see in MPP(insert status manager field then check)
Yes
after approval progress will be available in MPP as well as in Projectweb app as % complete .
Send
Progress for Selected Tasks
Send progress of selected task to status manager after approval update will be available in both MPP and Projectweb
app as % complete.
In Send
Progress for Selected Tasks Timesheet
Manager doesn't receive anything in his Approval center
because all the update directly go to Status manager Approval center.
Here you have to understand
that there are two role Timesheet Manager(for timesheet approval) and Status manager(for task
actual approval)

What is the difference between component(Y, Pb, Pr) and component(R,G,B)?

[I previously posted this question in another thread as hadn't realised how to post new question]
Q. What is the difference between component (Y, Pb, Pr) and component (R,G,B) ?
I’d previously thought I was reasonably savvy on all things HD, but when I turned my thoughts to looking into getting a mac mini to run part of my home cinema I realise I have some confusions around the above.
Here’s what I think I know:-
The mac mini has a DVI output of the type which can output both digital and analogue, and so via physical adapters it could be used to connect to displays that take HDMI or VGA style RGB leads.
I know on the market I can get a DVI to Component cable lead which would therefore lead me to assume it could drive my HD plasma with component input (Y,Pb,Pr), as I currently drive the HD TV via component cable with a SKY HD box (720p and 1080i), an xbox 360 (720p) and a progressive scan DVD player (480p), all through a Denon AV-amp.
The problem is, I’ve heard somewhere that the DVI to component is R,G,B only and that it is not Y, Pb, Pr which is making me wonder it a) this will work and b) if I really understand component video afterall.
I notice the Apple TV outputs Y,Pb,Pr but colours them red, green and blue, so am even more confused….
Hopefully someone can help educate me on this !

Thanks for this.
My Plasma is a Panasonic 42" Viera March 2005 model. No HDMI, No VGA.
It can process signals up to 720p and 1080i via the component (an interestingly it makes a huge difference over SD even though the native panel is 480..!?!)
Am I right in thinking that the iPod component cable will also be R,G,B and therefor might be a suitable trial? Ie. if the TV accepts the input from the iPod then it should work for the mini?
Only other thing of note is I'm doing all this via my Denon 1707 AV amp which does have the facility of upscaling, but I imagine it needs to stick to one format?
Thanks.

Whats the difference between Fatal1ty and Fatal1ty USB heads

Whats the difference between Fatal1ty and Fatal1ty USB headset? What is the $30 price difference for other than a USB connection?
Also, what is the advantage to using the USB port?
Still trying to decide on which headset to buy. I will be using these mainly for gaming and some music. Although i'm not real picky when it comes to music quality. Even considered the HS-1200 wireless. Which headset of these 3 has the best sound quality and better quality?

Any USB sound related item is going to use system resources instead of the non usb version. The non usb version uses the resources of the sound card and not system resources. So you should get cleaner sound with the non usb version.
But, be aware creatives tech support is not the best in the world. Keep that in mind when buying a product from them.

Whats the difference between and Album and a Smart Album

OK, just upgraded.... So, whats the difference between an Album and a Smart Album?
Also, I like to organise my stuff, so if I create a folder for each year, and then a project within that year, why is it that the photos are always in both - and then again if I chose to create an album specific to a project, they are there again.
So it might look:
          Folder (2012 Equine Photography)
               Project - Specific Events
                    Album - Big Barn Dressage May
Does this mean the individual photo is stored 3 times and using 3 times the space?
Thanks guys!

No. Conceptually the Master only lives lives in the single (time based) Project you import it into. Albums are just collections of pointers that point to images in various Projects.
"Big Barn Dressage May" could be a Project, but only if it is only one day and a limited number of image files; otherwise an Album. "2012 Equine Photography" should be an album or a Folder of Albums. "Specific Events" could be an Album or a Folder of Albums.
A Project should not be used as a Folder.
From an earlier post of mine:
Folders are indeed flexible organizational tools but IMO often overused. Folders can effectively hide contents from view and therefore require users to remember how folders are nested and what is inside them. Folders were the only way to deal with single-original film, but are IMO limiting to image database thinking.
The way I look at it conceptually:
Aperture is a database (DB), and each image file lives in one Project.
Albums are just collections of Pointers that point to individual image files living in one or more Projects. Since they just contain pointers, albums can be created or deleted at will without affecting image files. Very powerful. And Albums of pointers take up almost zero space, so they are fast and do not make the Library size grow.
Keywords can be applied to every image separately or in batches. Keywords are hugely powerful and largely obviate the need for folders. Not that we should never use folders, just that we should use folders only when useful organizationally - - after first determining that using keywords and albums is not a better approach.
As one example imagine the keyword "flowers." Every image of a 100,000 images Library that has some flowers in it has the keyword flowers. Then say we want to put flowers in an ad, or as background for a show of some kind, or to print pix for a party, or even just to look for an image for some other reason. We can find every flower image in a 100k-image database in 2 seconds, and in another few seconds create an Album called "Flowers" that points to all of those individual images.
Similarly all family pix can have a keyword "family" and all work pix can have a key word "work." Each individual pic may have any number of keywords. Such pic characteristics (work, family, flowers, etc.) should not be organized via folders.
So by using keywords and albums we can have instant access to every image everywhere, very cool. And keywords and albums essentially take up no space in the database.
Another approach is to use a folder "Family" for family pix, a folder "Flowers" for flowers pix and another folder "Work" for work pix. IMO such folders usage is a very poor approach to using an images database (probably stemming from old paper or film work practices). Note that one cannot put an image with family in a field of flowers at a work picnic in all three folders; but it is instant with keywords.
