I need help understanding an alignment panic when calling mutex_init

I am looking for help with a STREAM module that compiles and run under Solaris 10 on 32-bit and 64-bit Intel kernels but panics on a 64-bit Sarc kernel.
I have isolated the panic to a data alignment issue when my init routine calls either the rwinit and mutux_init routines with a pointer to a krwlock_t or kmutex_t structure that is not 8 byte aligned.
I am using "gcc version 3.4.3 (csl-sol210-3_4-branch+sol_rpath)" from the Solaris 10 install CD's with the following options:
gcc -Wall -fno-builtin -ffreestanding -nodefaultlibs -fpcc-struct-return -D_KERNEL -mno-app-regs -g -m64 -mcpu=v9 -D_SYSCALL32 -D_SYSCALL32_IMPL -D_ELF64 -D__sparcv9cpu -DSYSACCT -DC2_AUDIT
(I know some of these are redundant)
I have 4 locks along with a variety of other members defined in a structure used to by my driver code. If I manually arrange the structure to keep the lock variables on 8 byte boundries the module loads without a panic. However, if I let gcc handle the alignment or specifiy "__attribute__ ((aligned (8)))" on the lock variable definition the module panics on entry to the kernel rw_init or mutex_init routine with a BAD TRAP type 34 alignment error.
At this point I am lost. I'm guessing this is a gcc/sparcv9 issue but I have no idea how to code this properly. I'm hoping someone can help shed some light on the problem.

I found the problem. A shared header had a "#pragma pack(1)" with no matching "#pragma pack()". This was causing gcc to pack everything after the include.
I'm still a little unclear why my "__attribute__ ((aligned (8)))" on the actual variable did not override the pragma ??? but at least I found the culprit.

I need help understanding how the Apple components integrate to create a system across all my devices?

I need help understanding how the Apple components connect to create a whole system across all my devices?
Is there a resource that describes current system and associated functionality?
For example:
Buy A, B, C to achieve "X"
You will need:
an internet provider which supports <specs>
add D to achieve "Y"
You will need:
an internet provider which supports <specs>
add "E" to achieve "Z"
You will need:

For example, I am looking at the Gen 6 Airport extreme. For intended performance do I need broadband? if so what are the specs, or will basic internet service suffice? Do I need the internet provider's modem or does the Airport extreme replace that? And then I think, if I am doing this, I should also look at Apple TV....What do I need and Why? Then I look at the New Desk top coming out in the fall, and I think well, if I wait and get this, what does this component do for the system, and what becomes redundant? What does this awesome desktop do for my ability to sit and use a new macbook air when I travel or sit on the couch in my PJs?
If there was a place that plainly stated "if you buy the new dektop you can configure a system including only these components and achieve <this result> and by adding <additional components> you will achieve this result.
I have been to the genius store a few times, but I come out of there more confused unless I have SPECIFIC questions or already know what to buy.
A "System Configuration App" would be a really great sales tool--Just saying.

I have no idea what "fully optimized" means.
No Apple device will let you watch broadcast TV. The Apple TV is a good option for watching streaming TV from iTunes, NetFlix and Hulu. If you want to watch from other sources, you may need to look at other devices.
Any Mac computer or iPad will allow you to surf the web.
What business software?
Time Capsule is a good option for back ups.
Update what across all devices?
For accessing documents from all devices, a service like Dropbox is your best bet.
I have no idea what "step as far away from an internet provider as possible" means. If you want Internet access, you need an Internet provider.
Lighting fast speed for what? Processor? The specs are listed for all devices in the Online Store. Internet? We're back to the service provider.
Technology changes. The only way to keep pace with it beyond a couple of years is to buy new stuff.
The bottom line is you need to look at the specs for devices availble and at your budget and decide what best meets your needs. If you are unable to do that on your own, there are lot of technology consultants out there who will, for a fee, look at your exact situation, make recommendations and even handle the purchase and set up. Perhaps that would be the best route for you.
Best of luck.

Need Help Understanding How To Use iMessage Between Two iPhones

I have an iPhone 4 and my wife an iPhone 3GS. We both have iOS 5, but I have discovered something about iMessage I need to make sure I understand correctly. As I understand it iMessage can send text even if our voice carrier service is unavailable. I tend to loose signal inside the building I work in. I usually can get texts in and out, but sometimes not. But in testing the two phones sending iMessages, I've noticed is that if I have one of the phones with iMessage turned on and the other with iMessage turned off, the two phones will not be able to exchange text. Is that how it's supposed to work? Even though one of these phones can receive an iMessage doesn't mean the other one send one back. Can't the system detect when one phone is connected and another one not, and the one that is not gets sent SMS messages instead? I don't want to try to send my wife an iMessage because I can't get a voice signal in my building, but her have iMessages turned off and not able to get any messages from me, iMessage or SMS. I guess I need help better understanding how this actually works between the two phones so I can always get texts back and forth between my wife and I. My other misgiving is that this iMessage thing consumes my data limit. My wife gets unlimited because she had her phone before the limits were imposed, but I got on board after, so I am hesitant to use iMessage all the time because of it. I have no intention to send picture mail through iMessage, but the thing is if I wanted to switch to SMS to send picture mail to save data, but my wife's phone is set to iMessage, she won't get it. If this is how this thing is supposed to work, I'm not really impressed. Some insight would be appreciated

I think you are making this way too complicated. Why are you turning iMessage off? If you are at your office connect to the WiFi there and send your wife messages that way (unless your office is blocking the port iMessage uses). When possible the two phones will use iMessage but will revert to SMS is iMessage is not available if that option is set that way.
I would not worry about using up your data plan if you have the 2GB, text iMessages are going to be very small and MMS (picture) ones are not very large either. Unless you are sending hundreds of picture iMessages a day you will have a hard time using up your data.
If you are near an Apple Store you should explore signing up for an intro iPhone course and have them run through iMessage options.

Need help understanding syntax

Hi,
I need some help to understand the following syntax .
PPRAMImpl am = (PPRAMImpl)pageContext.getApplicationModule(webBean); What is this PPARAMImpl?
I know "am " is a variable . And with pageContext.getApplicationModule(webBean) we are trying to get the AM name for that page, then why do we need to add (PPARAMImpl) before pageContext.getApplicationModule(webBean) ?
For example in plsql , apps.testpkg.mainproc(param1,param2)
means
schema.packagename.procedurename(parameter1,parameter2).
So can you explain "PPRAMImpl am = (PPRAMImpl)pageContext.getApplicationModule(webBean)" in that manner?
pageContext.getParameter(EVENT_PARAM))
What is this ?
What are the possible values for EVENT_PARAM ? And by the way , I need help on setting a default value for one of my search parameters in a search region .
Correct me If I am wrong, this is what I thought
1. EOImpl has setters and getters for that attribute. So call the setter method in controller and set the value , if this is right then I don't know how to right the code ,can you give me some sample code ?
or
2. get the view object name and then set the value for that . like viewobject.setattribute('att name',att value'),if this is right then I don't know how to right the code ,can you give me some sample code ?
Thanks
Sri.

Hi,
No. These are not equal.
pageContext.getApplicationModule(webBean) return AM of type OAApplicationModule.
It would be fine if your variable am, is of type OAApplicationModule:
OAApplicationModule am = pageContext.getApplicationModule(webBean) // this would be fine.
But as you are using of type PPRAMImpl, you must have to type-cast that externally using:
PPRAMImpl am = (PPRAMImpl)pageContext.getApplicationModule(webBean);
If you are still not clear, then refer any java book or google for internal & external type-casting in java.

I need help retrieving Microsoft files lost when upgrading to OSX Mavericks

My daughter recently upgraded our Mac to the OSX Mavericks platform. Unfortunately, all of our Microsoft files, etc. are gone! I need to know how I can retrieve these files or if I can. I'm honestly not impressed with this new platform. I need help asap and your help is truly appreciated.

You have to make the backup yourself. That's your only protection against file loss whether accidental or catastrophic. In fact you should have at least two of them - each done differently and on separate drives.
If your files truly were "erased" then you can see if they can be recovered:
General File Recovery
If you stop using the drive it's possible to recover deleted files that have not been overwritten by using recovery software such as MAC Data Recovery, Data Rescue II, File Salvage or TechTool Pro. Each of the preceding come on bootable CDs to enable usage without risk of writing more data to the hard drive. Two free alternatives are Disk Drill and TestDisk. Look for them and demos at MacUpdate or CNET Downloads. Recovery software usually provide trial versions that enable you to determine if the software would help before actually paying for it. Beyond this or if the drive has completely failed, then you would need to send the drive to a recovery service which is very expensive.
The longer the hard drive remains in use and data are written to it, the greater the risk your deleted files will be overwritten.
Also visit The XLab FAQs and read the FAQ on Data Recovery.
Basic Backup
For some people Time Machine will be more than adequate. Time Machine is part of OS X. There are two components:
1. A Time Machine preferences panel as part of System Preferences;
2. A Time Machine application located in the Applications folder. It is
     used to manage backups and to restore backups. Time Machine
     requires a backup drive that is at least twice the capacity of the
     drive being backed up.
3. Time Machine requires a backup drive that is at least double the
     capacity of the drive(s) it backs up.
Alternatively, get an external drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
1. Carbon Copy Cloner
2. Get Backup
3. Deja Vu
4. SuperDuper!
5. Synk Pro
6. Tri-Backup
Visit The XLab FAQs and read the FAQ on backup and restore. Also read How to Back Up and Restore Your Files. For help with using Time Machine visit Pondini's Time Machine FAQ for help with all things Time Machine.
Although you can buy a complete external drive system, you can also put one together if you are so inclined. It's relatively easy and only requires a Phillips head screwdriver (typically.) You can purchase hard drives separately. This gives you an opportunity to shop for the best prices on a hard drive of your choice. Reliable brands include Seagate, Hitachi, Western Digital, Toshiba, and Fujitsu. You can find reviews and benchmarks on many drives at Storage Review.
Enclosures for FireWire and USB are readily available. You can find only FireWire enclosures, only USB enclosures, and enclosures that feature multiple ports. I would stress getting enclosures that use the Oxford chipsets especially for Firewire drives (911, 921, 922, for example.) You can find enclosures at places such as;
1. Cool Drives
2. OWC
3. WiebeTech
4. Firewire Direct
5. California Drives
6. NewEgg
All you need do is remove a case cover, mount the hard drive in the enclosure and connect the cables, then re-attach the case cover. Usually the only tool required is a small or medium Phillips screwdriver.

Need help understanding the local caching of jnlp when creating it via jsp

I'm trying to deploy an app via Web Start. I have occasions when I need to pass arguments, so I'm using JSP to create the JNLP and optionally write arguments.
I need some help in figuring out how to cover my different use cases with as few different jnlps as possible and am confused about the local cacheing logic.
Use 1
Initial install: I pass an init=yes url param which writes a preferences file <argument> to be passed to my app. I don't want this argument cached in my jnlp, as this will overwrite the user's preferences on subsequent launches.
Use 2
Subsequent offline launches: no url params passed.
Use 3
Launch via html link (in a CMS): passes a file=<filename> url param which creates a file <argument> for my app to open. Again, I don't want this argument cached, otherwise launching from, say, the desktop shortcut will reopen this file.
Can anyone explain how best to cover these three use cases?
TIA!

Did you solve this cache problem? I have a similar issue where I don't want it to use the arguments over again...

Need help understanding error message when syncing iTouch

I get an error message when I sync my iTouch with my MacBook. The error message reads as follows:
"iTunes could not sync mail accounts to the iPod...because an error occurred remapping record identifiers."
First, can anyone tell me what this message actually means? And second, any suggestions on how to resolve the problem?
Thanks.

it means a USB adapter. one that is connected to your computer in order to give you more USB ports than are built into your machine.

I need help understanding export options and optimizing for web

I have been using FCP X for a short while now and have a pretty good grasp on the editing capabilities. What I'm having a horrible time figuring out is the export/share options. The videos I create are typically approximately 1 minute in length and get posted to a web site (we have our own CMS and video player so I'm not using YouTube or Vimeo or anything like that). In order to post them I need them to be MP4s and then I have to create .webm and .ogv files. The source material I work with is generally great, high quality stuff, so I end up with very large output files from the initial FCP share master file options.
When I use MPEG Streamclip to make my MP4s I end up with files that are still quite large and I can't seem to ever get the file size manageable without losing tons of quality. I do not have Compressor, though if that will solve my problem I will put in for the expense of it. What I'm trying to understand is what sorts of settings I should be trying out to get my file sizes to be manageable without completely compromising my quality. And I know this can be done, because the company I work for pays for a great quantity of video work each year (from an outside production firm) and the clips provided are beautiful in quality and small in file size -- for example, I recently worked on a video and got it into the 40MB range before quality went to crap, working off the same material the production company we do work with had theirs down into the teens and looking beautiful!
To throw an even greater wrench in the works, I am working off a mac. But when my boss, on a pc, saves the mp4s I create (raw files -- not what is posted to the web) locally on his machine and views them from there the sound is always off a tad and the people in the videos look like they're lip synching.
Any advice on either of these is MUCH appreciated. I've been trying to figure this out properly for months, and only today decided to stop seeing if someone else had the same question and just post my own.
Bronwyn

Thank you Karsten, this was helpful I have utilized the Quality slider and the frame size options before though with limited results. I've never messed with the Limit Date Rate option as I don't know what I'm doing with it, I see you put 5Mbps. Is that a typical setting that I could use?
Using stream info, here's info on my original source file:
Stream: Charles_0023_2.mov
Duration: 0:00:51
Data Size: 96.51 MB
Bit Rate: 15.77 Mbps
Video Tracks:
H.264, 1920 × 1080, 29.97 fps, 15.64 Mbps
Audio Tracks:
MPEG-4 Audio stereo, 48 kHz, 127 kbps
Stream Files:
Charles_0023_2.mov (96.51 MB)
As a comparison, here's the info on a similar clip that the company we sometimes use created:
Stream: Charles_0019_4.mp4
Duration: 0:00:49
Data Size: 4.66 MB
Bit Rate: 0.80 Mbps
Video Tracks:
JVT/AVC Coding, 710 × 400, 29.97 fps, 635 kbps
Audio Tracks:
MPEG-4 Audio stereo, 48 kHz, 162 kbps
Stream Files:
Charles_0019_4.mp4 (4.66 MB)
I'm fine with bringing the frame size down some and modifying the limit data rate, but sometimes I feel like I'm forcing my video into something it's not and the quality suffers -- this is where my understanding of video work breaks down LOL. Any suggestions of how I can get my .mov into something like the the .mp4 above?
Also have you had any experience with mp4s not playing back properly on pcs?
Again, thank you!

Need help understanding profiles and color management

I made the big leap from inexpensive inkjets to:
1 Epson 3800 Standard
2 Spyder3Studio
I have a Mac Pro Quad, Aperture, PS3, etc.
I have a steep learning curve ahead, here's what I've done:
1 Read a lot of books, watched tutorials, etc.
2 Calibrated the monitor
3 Calibrated the printer several times and created .icc profiles
What I've found:
1 The sample print produced by Spyder3Print, using the profile I created with color management turned off in the print dialog, looks very good.
2 When I get into Aperture, and apply the .icc profile I created in the proofing profile with onscreen proofing, the onscreen image does not change appreciably compared with the no proof setting. It gets slightly darker
3 When I select File>Print image, select the profile I created, turn off color management and look a the resulting preview image it looks much lighter and washed out than the onscreen image with onscreen proofing turned on.
4 When I print the image, it looks the same as was shown in the print preview...light and washed out, which is much different than what is shown in edit mode.
5 When I open PS3 with onscreen soft-proofing, the onscreen image is light and washed out...just like displayed in PS3 preview. If I re-edit the image to look OK onscreen, and print with the profile and color management turned off, the printed image looks OK.
So, why am I confused?
1 In the back of my simplistic and naive mind, I anticipated that in creating a custom printer profile I would only need to edit a photo once, so it looks good on the calibrated screen, and then a custom printer profile will handle the work to print a good looking photo. Different profiles do different translations for different printers/papers. However, judging by the PS work, it appears I need to re-edit a photo for each printer/paper I encounter...just doesn't seem right.
2 In Aperture, I'm confused by the onscreen proofing does not present the same image as what I see in the print preview. I'm selecting the same .icc profile in both locations.
I tried visiting with Spyder support, but am not able to explain myself well enough to help them understand what I'm doing wrong.
Any help is greatly appreciated.

Calibrated the printer several times and created .icc profiles
You have understand that maintaining the colour is done by morphing the colourants, and you have understood that matching the digital graphic display (which is emissive) to the print from the digital graphic printer (which is reflective) presupposes a studio lighting situation that simulates the conditions presupposed in the mathematical illuminant model for media independent matching. Basically, for a display-to-print match you need to calibrate and characterise the display to something like 5000-55000 kelvin. There are all sorts of arguments surrounding this, and you will find your way through them in time, but you now have the gist of the thing.
So far so good, but what of the problem posed by the digital graphic printer? If you are a professional photographer, you are dependent on your printer for contract proofing. Your prints you can pass to clients and to printers, but your display you cannot. So this is critical.
The ICC Specification was published at DRUPA Druck und Papier in Düsseldorf in May 1995 and ColorSync 2 Golden Master is on the WWDC CD for May 1995. Between 1995 and 2000 die reine Lehre said to render your colour patch chart in the raw condition of the colour device.
The problem with this is that in a separation the reflectance of the paper (which is how you get to see the colours of the colourants laid down on top of the paper) and the amount of colourant (solid and combinations of tints) gives you the gamut.
By this argument, you would want to render the colour patch chart with the most colourant, but what if the most colourant produces artifacts? A safer solution is to have primary ink limiting as part of the calibration process prior to rendering of the colour patch chart.
You can see the progression e.g. in the BEST RIP which since 2002 has been owned by EFI Electronics for Imaging. BEST started by allowing access to the raw colour device, with pooling problems and whatnot, but then introduced a primary ink limiting and linearisation.
The next thing you need to know is what colour test chart to send to the colour device, depending on whether the colour device is considered an RGB device or a CMYK device. By convention, if the device is not driven by a PostScript RIP it is considered an RGB device.
The colour patch chart is not tagged, meaning that it is deviceColor and neither CIEBased colour or ICCBased colour. You need to keep your colour patch chart deviceColor or you will have a colour characterisation of a colour managed conversion. Which is not what you want.
If the operating system is colour managed through and through, how do you render a colour test chart without automatically assigning a source ICC profile for the colourant model (Generic RGB Profile for three component, Generic CMYK Profile for four component)?
The convention is that no colour conversion occurs if the source ICC device profile and the destination ICC device profile are identical. So if you are targetting your inkjet in RGB mode, you open an RGB colourant patch chart, set the source ICC profile for the working space to the same as the destination ICC profile for the device, and render as deviceColor.
You then leave the rendered colourant test chart to dry for one hour. If you measure a colourant test chart every ten minutes through the first hour, you may find that the soluble inkjet inks in drying change colour. If you wait, you avoid this cause of error in your characterisation.
As you will mainly want to work with loose photographs, and not with photographs placed in pages, when you produce a contract proof using Absolute Colorimetric rendering from the ICC profile for the printing condition to the ICC profile for your studio printer, here's a tip.
Your eyes, the eyes of your client, and the eyes of the prepress production manager will see the white white of the surrounding unprinted margins of the paper, and will judge the printed area of the paper relative to that.
If, therefore, your untrimmed contract proof and the contract proof from Adobe InDesign or QuarkPress, or a EFI or other proofing RIP, are placed side by side in the viewing box your untrimmed contract proof will work as the visual reference for the media white.
The measured reference for the media white is in the ICC profile for the printing condition, to be precise in the WTPT White Point tag that you can see by doubleclicking the ICC profile in the Apple ColorSync Utility. This is the lightness and tint laid down on proof prints.
You, your client and your chosen printer will get on well if you remember to set up your studio lighting, and trim the blank borders of your proof prints. (Another tip: set your Finder to neutral gray and avoid a clutter of white windows, icons and so forth in the Finder when viewing.)
So far, so good. This leaves the nittygritty of specific ICC profiling packages and specific ICC-enabled applications. As for Aperture, do not apply a gamma correction to your colourant patch chart, or to colour managed printing.
As for Adobe applications, which you say you will be comparing with, you should probably be aware that Adobe InDesign CS3 has problems. When targetting an RGB printing device, the prints are not correctly colour managed, but basically bypass colour management.
There's been a discussion on the Apple ColorSync Users List and on Adobe's fora, see the two threads below.
Hope this helps,

Need help understanding a project please

Hi, i just finished reading through this lab that i'm supposed to do, but have no idea what i am supposed to do. Could anyone here possibly help me understand it in an easier fashion? I would really appreciate it.
Assignment:
For this assignment, we will create a number class that can help us create classes for objects like clocks or angles. The number class will have to be general enough so that we can define different bases for it. Clocks need numbers of base 24 (or 12) and 60. Angles need numbers of base 360 and 60. For now, we are going to simplify things and only define constructors, a toString method, and an increment method. Of course, a complete number class would have many other methods, such as adding, subtracting, multiplying, comparing, and negating the numbers. Since a number is made up of digits, we will also define a digit class. The number and digit classes appear very similar because they have nearly the same methods. The differences are in the implementations of the methods.
Write a number class that represents a number with a given base. The number class has two constructors. The default constructor sets the base at 10 and the value to 0. The other constructor accepts a decimal value and a base. The constructors will have to create all of the digits (as objects of the digit class) and store them in some kind of list. Create a toString method and an increment method. These two methods will use the corresponding methods of the digit class to do most of the work for them.
Write a digit class that represents a single digit with a given base. The digit class has two constructors. The default constructor sets the base at 10 and the value to 0. The other constructor accepts a decimal value and a base. Create a toString method and an increment method. The increment method should return a boolean: true if there is a carry and false if not.
For both classes, you can assume that the bases are restricted to binary, octal, decimal or hexadecimal and the values are non-negative.
Instructions:
Write a test driver that proves that your classes work.

Am i just reading into the lesson to much and making it way more complicated than it actually is?Like I said, I'm not going to try to interpret the whole thing for you but a) It tells you what to do with the c'tors, and b) I would always assume that "create a method" or "define a method" or whatever he says means "create a *fully functional, correct* method", unless he explicitly states to leave it empty for now.
My advice is to use your best judgment as to what's expected, and get started on that basis. At your first opportunity to speak to your teacher, explain your uncertainty and the assumptions you made.
If you have specific questions along the way, post them here, along with your code or an SSCCE.
When you post code, use the CODE button or [code] and [/code] tags to preserve formatting and make your code readable.

Need help understanding how DNS should be set up...

Some time back I was advised to switch my network settings such as to start using the OpenDNS servers rather than the ISP (Comcast) servers that were setup by default... I did so, at least I did so in the Network/DNS settings on my MacBook Pro... But I just noticed today that my Airport Extreme Router has its own DNS settings and those are still set to the Comcast settings...
How does all this work??? Which DNS settings matter, the ones in the Network setup for each Mac or PC in my home network??? Or do the Router settings win over everything else???
I need a brief tutorial on how to properly set up the DNS settings not just for a computer but for an entire home network... Any feedback???? thanks...

I do appreciate the help... One other interesting thing I encountered recently... I was in Oakland airport where they have free wifi... I found myself unable to connect though I had been successful in other earlier visits there.... I got curious and played for a while... What I discovered (after an hour of trying but I had time) was that I had to change my DNS settings on my computer to an address very similar to the home page IP of the airport website... I don't recall now how I came to finally figure that out but it was happenstance more than anything... I vaguely recall me stumbling upon some message where the airport was suggesting a DNS value to use. It popped up on the screen or inside the Network settings or somewhere.. I think it was when I was walking through the connection wizard which I did several times before I had success...
But I've never had that experience in airports before... All of this shows how my ignorance of DNS keeps finding ways to impact my ability to "get connected" when here or there... Again, just another interesting DNS issue I stumbled upon recently... thanks...

Need help understanding communicating with a thread

I am trying to write a library of a MUD engine that runs in its separate thread, but I am new to Java and not sure I have the concepts right. The heart of it is a class called Game, that implements the Runnable Interface and has 2 key methods - void DoCommand(String command) and String GetUpdates(String lastUpdate).
* The Run() method runs an infinite loop that processes queued commands when they are due, and pauses (wait() or sleep()) in between. The results are queued in an update list.
* The DoCommand() method queues commands to be processed in Run().
* The GetUpdates() method pulls updates from the update list one at a time.
Will there be a problem if DoCommand() or GetUpdates() are called while Run() is paused or running?
How do I get DoCommand() to wake Run() when a new command is received?
BTW: I am new to Java so please make the answers simple enough for me to understand.
My theoretical code skeleton is below, but I am not confident in it given these questions I have.

OK cotton.m. I will try that and see what happens.
What about my question about which thread DoCommand() will run in (my second post in this message thread)? Any answers? I think that's key to me understanding what is needed to get my code to work the way I want, but I don't know how to test which thread it is running in.Possibly by interrupt.
Or possibly by adding the command to a command queue which in turn would notify a thread waiting on the queue for the next command.

Need help understanding ipv6

Hi... I have a new wireless network camera and I've been successful at getting it connected but there is a big question as to whether I have the ipv6 part of it set up correctly... By the way, on the router end I have an AEBS...
I've been trying to understand the correct format for an ipv6 IP address... I found a little Windows based utility called IP Convert that when I put in an ipv4 address like 10.0.1.252, it converts that to ::0A00:01FC which is simply the hex equivalent of the above decimal numbers... On the other hand the network camera produces a page that shows the same ipv4 address (10.0.1.252) in the ipv6 realm as one of the following two lines... (There is confusion as to which is really the ipv6 IP address but I don't understand either one or how they might relate to the simpler one, ::0A00:01FC, above... These two lines are,
fe80::280:f0ff:fea7:8c5c
2002:4c67:6043:0:280:f0ff:fea7:8c5c
On one of the camera pages, both the above lines sit next to the single header, ipv6 IP Address...
Can anyone make any sense out of these two lines I've posted above and how they might relate to 10.0.1.252 in the ipv4 realm???
Any help would be much appreciated... thanks... bob...

Hi Robert,
You're correct -- IPv6 addresses are written in hex. But you can't just convert your IPv4 address to hex and have it be IPv6. IPv6 and IPv4 have different address spaces -- there is no connection between your IPv4 address and your IPv6 address.
It sounds as if your network camera does in fact support IPv6. Out of curiosity, what model is it?
Both of the IPv6 addresses you listed are being used by the camera. The fe80 address is its link-local address. These addresses are not routeable. They're used for internal "housekeeping" communication on the subnet (more technically, they're used for the IPv6 replacement for ARP, which isn't used in IPv6).
The 2002 address is the camera's public IPv6 address.
Having two addresses like this is very common for IPv6 devices. IPv6 devices always have the fe80 link-local address. In addition, they might have one or more public IPv6 addresses (which don't always start with 2002).
Hope this helps,

Need help understanding Time Capsule file structure and how to get it back

I have the original Time Capsule on which I backup both my Mac Pro and my wife’s Macbook. When Snow Leopard came out, I successfully used the ‘Restore from Time Machine’ feature on my Mac Pro so I know it has worked. However, my wife’s MacBook harddrive died the other day and I was trying to do the ‘Restore from Time Machine’ and all it would find was a backup from April (when I put her in a new larger drive). Time Machine would not find any backup files newer that April. She stated that she had seen the the Time Machine backup notices regularly and as recent as the day the haddrive died (Nov. 23) so I figured that I should have no problem. Here is what I have found in my trouble shooting and what leads to my questions below.
This is the file structure I found: (note that our ID’s are ‘Denise’ and ‘John’)
*Time Capsule* (the drive as listed in my Finder window sidebar under ‘shared’)
>Folder called ‘Time Capsule’ (when logged in as either ‘Denise’ or ‘John’)
>>Denise Sparsebundle
>>>Backup of Denise’s iBook (mounted image)
>>>>Folder called ‘Backups.backupdb’
>>>>>Folder called ‘Denise’s iBook
>>>>>>Single folder with old April backup (not the right files)
>>John Sparsebundle
>>>Backup of John’s Mac Pro (mounted image)
>>>>Folder called ‘Backups.backupdb’
>>>>>Folder called ‘John’s Mac Pro’
>>>>>>Folders containing all my backup files
>Folder Called ‘Denise’ (if logged as ‘Denise’)
>>Denise’s Sparsebundle (a disk image)
>>>Backup of Denise iBook (the mounted image. Name from old machine)
>>>>Backups.Backupdb
>>>>>Denise’s iBook (Contains the backup I need)
>Folder Called ‘John’ (if logged in as ‘John’)
>> (empty)
For some reason, my wife’s backup files are stored within a folder located at the top level of the Time Capsule drive called ‘Denise’, however, mine are within a folder called ‘Time Capsule’ which is at the same level as the ‘Denise’ folder.
For some reason, when trying to use Time Machine to recover, it bypasses the top level ‘Denise’ folder which contains the correct files and goes into the ‘Time Capsule’ folder and finds the outdated backup files.
I would assume that both my backup files and my wife’s should be at the same level of the Time Capsule.
I was eventually able to use Migration Assistant to recover the files after installing a fresh OS and mounting the correct Sparsebundle image.
So, my question, how do I get this fixed so that if I have to recover a drive with Time Capsule, it will find the correct files.
Sorry for the long post and thanks in advance for any help.

What I was trying to determine is why different backups for one particular machine are located at different file structure levels on my Time Capsule and why the most resent one for that machine is at a different level that for my other machine. Also, what is the correct level that both machines backups should be at.
well John, first can you clarify if you are on 10.4.8 as your profile suggests ? if so, i'm wondering how you can use TM at all because TM was introduced with Leo. if you're not on 10.4.8, please update your profile. if you could, please also indicate details of your machine such as available RAM, processor, etc.
second, what OS is your wife's machine running ?
third, i frankly don't know too much about TM's file structure or if there indeed is such a thing as the correct one. however, i do know that it is best to leave TM to do its thing (as long as it's working). FWIW, though off-topic, you may want to have a look at this read for further information.
last but not least, i see TM backups to my TC only as a part of my backup strategy. the backbone of my strategy is to create bootable clone of my startup disk(s) using e.g. Carbon Copy Cloner on a regular basis. while TM is capable of doing a full system restore, i don't trust it as much as a working clone. i use TM to retrieve a file i accidentally trashed a week ago but you cannot boot from a TM backup if your startup disk goes belly up.
If I have missed this information in either the FAQs or the Troubleshooting article, I would greatly appreciate being pointed to it .
i expect you didn't miss anything and i'm sorry you didn't find any help there. perhaps if Pondini (author of the FAQ and troubleshooting user tips) reads this thread, you will get the necessary advice on the file structure and more besides.
good luck to you !
