Can someone explain HomeKit please?

I read that homekit is suppose to be a feature of the OS where it allows you to interface with any hardware that is homekit compatible (as opposed to using many apps to control many things).
Ok all makes sense. But where is the homekit app?

Yep, I read the whole thing. It didn't make any sense. Why would you want to use homekit SDK to build apps when the whole point was to have a central app for all these devices?
If you are going to build an app for each piece of hardware then why use the SDK?

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 the icloud to me please? Where are all my old pictures and how can I see them? Photostream only holds 1000 and when I sync my icloud to my mac it only imports what is on my photo stream.

Can someone explain the icloud to me please? Where are all my old pictures and how can I see them? Photostream only holds 1000 and when I sync my icloud to my mac it only imports what is on my photo stream.

When you enable photo stream on your Mac, in imports photos currently in your photo stream. However, photo stream only keeps photos for 30 days, even though up to 1000 photos will remain on your device until you delete them. When you enable photo stream on your Mac, you will only receive photos added in the last 30 days, as the others are no longer in your photo stream.
If you want to get all your old photos on your Mac, save them to your camera roll (if they aren't already there) by opening your photo stream album, tapping Edit, tap the photos, tap Share, tap Save to Camera Roll. Once they are in your camera roll, import them to your Mac as explained here: http://support.apple.com/kb/HT4083.
Another option would be to create a shared photo stream containing the older photos and invite yourself (as explained here: http://help.apple.com/icloud/#mmc0cd7e99). Then check Shared Photo Streams in iPhoto>Preferences>Photo Stream and you will see this shared photo stream on your Mac.

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.

Can Someone Explain the order of things Using Swingworker?

Hi:
Can someone explain very clearly the order of things using Swingworker? Please do not refer the SUN tutorials. I am totally dead in the water with a very large application and the order of things is not sensible. Also, if the worker thread is too long, the GUI gets updated, but my progress bar (killed right after in the finished method) remains running in some instances only.
Can someone explain any debugging methods for thread work?
I am a veteran programmer of 19 years and this one's got me. The event dispatch thread returns immediate, the GUI responds well, but the progress bar setVisible(false); ... just after in the finished() method (on Event Dispatch thread) does not go away, continues running, only on very long (large query) work. I'm truly stumped. I have successful applications of the Swingworker use, the progress bar, and everything works fine. Not this one.
Debugging threads is what I need. Or some tool that visually shows threads as the program runs.
Thanks for any help,
PiratePete

Thanks. I guess I should count my blessings when using free stuff. But I have been impressed with what the J2SDK has to offer. I have been writing a complicated application that I am going to market and most of my problems have been "design" in nature.
Thanks again,

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 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.

This is no longer done via iTunes.
Use whatever CD/DVD burner software is installed on your computer.
Add the iTunes media folder to the list of files/folders to burn to disc.

I had backed up my IPhone 4s on iCloud on Jan 19. I am now trying to do another back up but it says the time required is 7 hours. It appears to long a time for 1GB of data stored on the iCloud. Can someone help me please?

To be honest, that sounds about right.
For example on my 8Mbps (megbits) down service I get around 0.4Mbps upload. That is the equivalent of (very approximately) 3Mb (megabytes) per minute or 180Mb per hour. Over 7 hours that would be just over 1Gb.
Obviously, it all depends on your connection speed, but that is certainly what I would expect, and that is why I use my computer for backing up, not iCloud. So much quicker.

I cannot find a way to sort the bookmark folders themselves alphabetically by name.I am not talking about in a view mode but in the way they are displayed when I click on my bookmarks tab. Can someone explain to me how to accomplish this.

I have a lot of various book mark folders with websites contained within each folder. I am able to sort the websites within each folder alphabetically by name but I cannot find a way to sort the bookmark folders themselves alphabetically by name.I am not talking about in a view mode but in the way they are displayed when I click on my bookmarks tab. Can someone explain to me how to accomplish this other than manually dragging them as this is extremely hard for me due to the fact that I am a quadriplegic with limited hand movement dexterity

Bookmark folders that you created are in the Bookmarks Menu folder. "Sort" that folder.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.
