Can someone explain activity monitor?

Can someone tell me the difference between
active memory
wired memory
inactive memory?
I have 2gb's of mem but I am getting a few page outs. It says I am using 1.96 GB's of memory but I only have Parallels (384mb given to it) and mail, safari open?? Over 900MB's of memory are "inactive" but I don't understand what that means.

Wired memory
This information can't be cached to disk, so it must stay in RAM. The amount depends on what applications you are using.
Active memory
This information is currently in RAM and actively being used.
Inactive memory
This information is no longer being used and has been cached to disk, but it will remain in RAM until another application needs the space. Leaving this information in RAM is to your advantage if you (or a client of your computer) come back to it later.
Free memory
This memory is not being used.

Can someone explain purchasing, activating and signing up for iPhone.

Hi, iPhone hits UK in November and I'd like to be prepared. Can someone explain to me how it's going to work. In the USA where do you buy the phone - the Apple store, and what do you do just walk in a buy the actual phone as if it were an iPod? And then how does activation work? What is it, just registering the iPhone with Apple or signing up with the network provider? What stops you from just buying the phone and putting another AT&T or O2 sim in and not signing up for one of the contracts?

Presuming that it will look pretty much the same as it did for US customers, it will be something like this..
You walk into your local Apple store and purchase an iPhone, or you can order one through the UK online Apple store (or, presumably, O2 will sell them in their local shops).
You connect the iPhone to any computer which meets the minumum system requirements. It will recognize a new, unactivated iPhone and take you through the activation, which includes:
1. Entering your name, address, and payment info
2. Create an iTunes Music Store account if you do not already have one
3. Select which type of call plan you want (how many call minutes, how many text messages, etc)
4. Specifying whether you want a new number assigned or want to port your number from another provider (assuming this can be done in the UK)
You will then wait while the activation is completed, which can take several minutes. Once your phone is activated you will be able to make calls, send text messages, and use all the other functions of the iPhone, including syncing your contacts, calendars, and music to it. If you are porting a number from another service, once the port is complete you will be able to receive calls. If you are being assigned a new phone number, you will be able to receive calls right away.

Can someone explain me well when the infopackage use batch or dialog?

Hi Gurus,
can someone explain me well when the infopackage use batch or dialog?

Hi ,
first of of in Bi_btch job nothin comes in the log .. but if you use PSa and then into data target then it willl definatly create background jobs .. but i feel it doesnt relate to the concept you are taking about ..
if you us e a sepeate update from PSA step the it will create backgroung jobs ..of king bi_btch and if you push the packets maually then it will create jobs like bi_book .. thats the diff ..
The initialization and execution of an InfoPackage is implemented as a process type in the process chain maintenance. The Start Later in Batch setting is hidden if the InfoPackage is used in a process chain. This is because the start of the request is determined by the process chain itself.
If you do not use the InfoPackage in the process chain maintenance and you want to process the data request in the background, select the radio button Start Later in Batch and define the required start time. If start times already exist for this data request, this is indicated with a next to the Scheduling Options pushbutton. You can change the start time using Settings Options. You can also enter an end date for the data request with a background job.
If you schedule an InfoPackage in the batch later, the background request job runs until all data is updated in BW. This is displayed with a corresponding indicator in the Schedule tab page. The load process remains active until the data is updated.
For example, this gives external scheduling tools the option of monitoring the request job. The job then also runs with a request from an SAP source system as long as the source system has sent the data to the BW system and posted it or until the monitor sets the request to red. In the job log, a success or error message is displayed according to whether the request was posted successfully or not.

Can someone explain wireless internet to me?

Ok so I have a new macbook pro (purchased yesterday).
I don't really understand wireless internet - can someone explain what I have to do to get wireless internet.
I'm currently on ADSL. I did notice that I was able to pick-up a wirelesss internet connection in my lounge room. So I'm assuming neighbours near by have wirelesss iternet (would that be correct)?
Do I have to purchase a base station for wireless to work correctly in my house?
Help would be appreciated.

Hi, Tea. Hope you like your new MBP.
I'm not the expert, but I have a Airport Express base station. I plug my cable modem into it, my speakers, and my printer, and I can do everything wireless. Airport was (and maybe still is) $100.00. I know you can get other stations (non-apple) far cheaper. And if others do, more power to them. But I don't know whether they work with itunes. You can get the extreme base station for more. I think it gives more range and may be faster.
It's pretty simple to set up. You plug it in the wall. And then plug in your usbs into the airport. You then set it up by clicking on your internet activity button near the top right of your screen.
As for using other neighbor networks, I don't know what the legalities are. But I've heard it's not safe --- and that's enough for me. When you set up your network, you can encrypt it with a password. I see several neighbors' networks too, but theirs are password protected. You should do the same. Plus, theirs may be slower than you'd like, or sometimes out of range.
Good luck!

Can someone explain shortest path switch over in Multicast?

Can someone explain shortest path switch overin Multicast?

Hi,
Shortest path switchover is used in PIM Sparse mode.
The concept of Sparse Mode is the multicast traffic should only be delivered when there are active receivers in the network. To accomplish this SM has explicit Join and Prune mechanism rather than Flood and Prune used by Dense mode.
When the last hop router (where receiver is connected) receives an IGMP join message, it sends a PIM Join towards RP. This creates shared tree from the last hop router till RP along the routers.Thus a shared tree has been created from last hop router till RP.
At the same time the above procedure was taking place, the first hop router (where source is connected) starts sending PIM Register messages to RP (when source starts sending multicast traffic). This register messages are unicast so that the intermediate routers will not aware of multicast traffic. When the RP receives Register messages from first hop rotuer, it does below checks after decapsulation:
1. Are there any shared tree for the specific multicast group. If yes then send a SPT join towards first hop router so that the multicast traffic from source will be delivered to RP via native multicast rather than encapsualted packets. Also RP sends Register Stop message to inform first hop router to stop sending encapsulated multicast packets.
2. When there are no active groups in RP (i.e RP has not received any PIM join for the multicast group from any last hop router), RP sends a Register Stop message.
By this the traffic from source flows via SPT till RP. From RP it flows via shared tree till receiver. Everything is fine till now. But the drawback in SM is placement of RP and the load on it. Since RP is located in a central location chances are there that the multicast traffic from source takes a longer path to reach the receiver. This will result in increase in latency along with increase in RP load.
So in those cases, it is desirable for the multicast traffic from source flows to receiver on optimal path. This is done by SPT switchover and this is done when the multicast group traffic crosses the SPT threshold configured. In Cisco the default SPT threshold is Zero kbps. So when the last hop router receives first multicast packet via shared tree, it does SPT switchover. This is done by sending a SPT Join towards the source thus bypassing the RP. Now the traffic from source prefers the most optimal path to reach the receiver.
The same time, last hop router sends a PIM prune towards RP to inform it that it does not want multicast traffic over shared tree. This is done to avoid duplication of the multicast packets over SPT and shared tree.
Few facts:
1. Last hop router needs information about the source to send SPT Join and this can only happen when it receives few initial multicast packets via RP shared tree.
2. If you do not want the last hop router to fall back to SPT switchover, then configure SPT threshold to infinity in last hop router.
Sorry for the long post.
HTH.

HT5463 In my opinion, when the Silence setting is "only when the device is locked", it contradicts the settings you set above, like Manual. Can someone explain how these settings work together?

Can someone explain how these settings work together? Manual seams to contraduct the SILENCE setting at the bottom of the Do Not Disturb page. It's very confusing.

You should have seen information in the support document that you linked from. It used to be with the first version of Do Not Disturb that it would only function when the device was locked. That changed with iOS 7, and not it can be active all of the time. With it on Manual, it is on, but if you have the device "awake" that you can still receive calls/texts, etc. Sort of like you have the phone awake, so it isn't a problem for you to receive things. If you set the settings for Always, this means you can be doing things on the phone and not be disturbed by anything else. Does that make sense?

I posted in this thread an example that illustrates how to use the 3d graph to do surfaces ac lines.
The type of data that you present to the 3d graph depends on which mthod you are using. In general you want to present a set of points that need plotted. These points are defined by taking one value for each of the XYZ and sometimes W arrays.
Explanation:
You want to plot a surface that is defined by four point (X0,Y0,Z0,W0), (X1,Y1,Z1,W1), etc. You can present the values using (4) 2-d arrays each of which have four values at index (o,o), (0,1), (1,0) and (1,1).
Thie first point plotted would be the point that is defined by taking (0,0) from each of the arrays.
So as you can see from the above all of your arrays should be of the same size and dimensions for this to work.
Look at the Example i posted in the other thread and try some small experiments with small data sets before you jump to anything complicated.
I hope that helps,
Ben

Can someone explain this difference in Mac vs Win policy ?

I can download a MathScript module for evaluation with the Windows evaluation version, but for the Mac, I have to first buy LabVIEW (the module is free, just can't be evaluated). Can someone explain the logic behind this nonsense ?

NI's activation platform doesn't work on the Mac or Linux operating systems. We created a "special" evaluation version of LabVIEW for the Mac, but after the 30 days, it requires you to uninstall it and install the regular version of LabVIEW, which doesn't have activation.
VISA is offered as a free download because it a device driver, and by practice, all of NI's device drivers are free. However, the MathScript RT Module is an add-on for LabVIEW. The reason that the Mac and Linux versions are free is because we don't have LabVIEW Real-Time for Mac or Linux, and the real-time capabilities for the LabVIEW MathScript RT Module are the primary reason for the cost of the Module in the first place. This ability to deploy custom .m files to embedded hardware, and run them deterministically, as well as the plug-in tools to do profiling and testing, is a huge differentiator for MathScript on the Windows platform. However, that functionality doesn't exist on the Mac or Linux platform.
The reason you can't download the Module is because we need to be able to track who the users are. Each new release of LabVIEW brings a new version of the MathScript RT Module, and we physically mail the new media to all of the users who have "purchased" the free Module, just like with any purchased Module. If we simply said go download it, then each person would have to go re-download it with each release.
"Go stuff yourself" is certainly not the intention. You will be able to use the Mac version of MathScript (free) on the evaluation version of LabVIEW for Mac. To find this version, navigate to http://www.ni.com/trylabview/ and choose to "See Download Options". The mac version is linked within this page.
I hope you find this information both helpful and satisfactory.

Can someone explain how to set up an administrator account so that I can have my phone and my daughters have separate apple ids?

I mistakenly updated to the latest version of iOS and ever since then I can send messages to my daughter and I receive them but she does not. She has an iphone also and her phone is under my apple id also. Someone told me that I could set up an Administrator Account so that she can still be under my account but she has her own ID and that will fix the problem with text/imessages. I can't find anything on the website that explains how to do that. Can someone explain that to me?
Thanks!

I'm still not clear on what you are trying to accomplish. If you have an iPhone and she does as well you should have your own Apple IDs.
If you want to pay for any purchases she makes with her phone as far as apps/music goes than that is what Family sharing is for.
In my case my Wife and I are setup for family sharing. When she purchases music/apps it charges my credit card. This setup also allows me to share my past music/app purchases with her and vice versa.

Please can someone explain how to delete email addresses? I have people who when I type in their name it comes up with the correct email address but then when you hit return to confirm it promptly changes the name to someone else (always the same someone

Please can someone explain how to delete and email address that when typed in brings up one name but when you hit return to confirm it jumps to another name. I can't find them in my contacts list but they do come up when you type the first few letters of a name.
EG If I type xyz and the name of the person comes up, when I press return to confirm that's the one I want then it jumps to [email protected], always the same def address.
I can't fathom it out.
Thanks
Terri

Try this:
Start a new email. In the To address bar, type in xyz like you normally do, press return to confim, and when the address you want to remove shows up in the address bar, move your cursor over the address you want to delete.
A small triangle next to the name will show up. click on it, a drop down menu will open, click Remove from Previous Recipients List. Then do the drop down menu again and Remove Address.
Good luck.

Trying to understand RSTP - Please can someone explain this?

Hi Group
I am still confused about how RSTP is implemented. From what i understand the major difference is that STP
used Timers for Loop prevention whereas RSTP coordinates between neighbors via messages (proposal/aggreement) to turn on links
more quickly after topology changes and is "timer free".
However, I have not noticed any difference in the configuration from the legacy STP
configurations and the RSTP configuration on cisco devices. Or are there any differences??
I have read in documentation that RSTP natively includes features like UplinkFast, BackboneFast and PortFast. So are these features now obsolete
and not needed to be configured if you are running RSTP. (Although i have seen Portfast still configured along with RSTP on many switches)
Also can someone explain the below Points from Cisco Documentation
1) should STP be disabled on edge ports all together as suggested below?
"STP edge ports are bridge ports that do not need STP enabled, where loop protection is not needed out
of that port or an STP neighbor does not exist out of that port. For RSTP, it is important to disable STP
on edge ports, which are typically front-side Ethernet ports, using the command bridge
bridge-group-number spanning-disabled on the appropriate interface. If RSTP is not disabled on edge
ports, convergence times will be excessive for packets traversing those ports."
2) It seems RSTP relies on duplex setting to determine inter-switch links. What is the configuration to explicitly
configure RSTP link types? (I couldnt find this in the documentation)
"RSTP can only achieve rapid transition to the forwarding state on edge ports and on point-to-point links.
The link type is automatically derived from the duplex mode of a port. A port that operates in fullduplex
is assumed to be point-to-point, while a half-duplex port is considered as a shared port by
default. This automatic link type setting can be overridden by explicit configuration. In switched
networks today, most links operate in full-duplex mode and are treated as point-to-point links by RSTP.
This makes them candidates for rapid transition to the forwarding state."
Also i am a bit rough on my RSTP knowledge even after skimming a few Cisco documents. Can someone please explain this in simple way.
Thanks in advance

to configure it on a device:-
spanning-tree mode rapid-pvst
PortFast/UplinkFast & BackboneFast were cisco "Enhancements" to 802.1d STP. RSTP just incorperates them. If you want to configure portfast, the command is still "spanning-tree portfast"
OK
1) That is your choice - I have bitter experiance of users/IT admins just plugging hubs/switches in when ever they can. Also cabling the switch back to itself creating a cabled loop. So my advice to you is to leave STP enabled on all switch ports, BUT enable BPDUGuard - this is a life saver, if you have configured portfast.
2) duplex auto! or duplex full (overiding)
I really suggest that you read the 802.1d standard, once you understand normal spanning-tree - RSTP will come to you.

CAN SOMEONE EXPLAIN ME THE DISPLAY QUALITY

I have just purchased a new macbook pro 15" 2.4ghz. Im a designer, i havent even created my appleid, im on my sisters... i made a sacrifice to buy this $2700 laptop.
and Im so dissapointed...
I CANT SEE SMOOTH GRADIENTS.. all i see are ugly lines... i dont get it, for such a high class LAPTOP.
Apple support please help me solve this. ive been reading forums about 6bit screens for this laptop.. i dont want to believe that. can someone explain? im returning this...

I can verify that all of Apple's laptops use 18 bit (6 bits per Red, Green Blue) color, which is about 260,000 colors. The OS then using dithering to fake the missing colors. Despite what you have read, they are incapable of 24 bit 'millions of colors'.
The problem with this argument is that, when it comes down to it, the color displays are made up of dithered red, green, and blue elements anyway. We accept that this form of display gives us "full color", so it's difficult to argue that millions of colors can't be represented using the same mechanism. It's not quite 16.7 million (more like 16.3 or something) but Apple's text has always taken care to read "millions of colors" rather than 16.7 million (which you'll still see on the specifications for the Cinema displays).
Just for informational sakes though, these kinds of 6-bit displays don't rely on OS spatial dithering; they actually make use of their very fast switching to perform temporal dithering, switching a pixel between two shades very quickly to generate an in-between shade. That's why for most people the result is usually visually indistinguishable from true 8-bit color, and doesn't look like what you'd see with traditional dithering.
If the OP is noticing severe banding on gradients, it's more likely to be an issue with color profiles than with the display being 6-bit.
