Backing up your backups: the right way.

Hello everyone.
I've been searching a lot online but haven't found anything that could help me doing what I need to.
Have anyone ever tried to make a Backup of only one particular time machine backup ?
Let me explain:
I have a hard drive full of time machine backups. I need to make a copy of it, However I am only interested in cloning a single one of those backups (corresponding to a single date).
I dont have enough storage space to copy the whole "Backups.backupdb" folder, and I'm only interrested in a very particular backup corresponding to a special state my Macintosh HD was in a couple of years ago after a fresh install. Indeed if my Time machine hard drive would die, I need to make sure I keep a safe copy of what my computer was like on this very day.
I was thinking about entering the time machineapplication, navigating back in time to the date I am interested in, selecting the whole hard drive in the finder and clicking "restore". However I am afraid it would only copy hard links, without replacing them with the original files. I would end up with an incomplete backup where most of the files are just dummy links
Can anyone think of a proper way of doing this ?
Thanks a lot.
Best

Upgrading Mother Board (P55-GD65 with i3 processor) BIOS [/b] from 1.3 to 1.6 corrected my Computer re-starting soon after the Boot sequence began. Putting the four 2GB RAM in one at a time in the suggested order in sequence with the socket numbers fixed the problem earlier, but only for the next, one boot. The problem then returned as long as all 4 DRAM were installed. Raising the DRAM voltage did not improve things.
I used the Forum's program for flashing the new version of Bios using USB Flash Memory for boot into DOS.
Thank you, DaLoona, for your post notifying me this had to do with the motherboard and was probably not a failure, but a "normal" occurance in certain conditions. I was no longer inclined to return the board and perhaps end up with the same error in the replacement, and no longer worried about the rebooting doing damage.
In Bios Setup I had already reduced an entry to do with number of overclocking tries from 3 to 1 (the minimum choice) which reduced the number of re-boots to 1.

Running your memory the right way/ running 4 DIMM slots on P55 boards

Dear Forumers,
Lately there are a lot of questions, about motherboards from the P55 range not starting on first boot.
This could be due to wrongly arranged memory DIMM's in your slots.
Some people out there, like me, were convinced that you could choose either dualchannel.
Well, its not the case.
Like I was pointed out earlier, you must use a certain slot, otherwise the memory will not be detected properly.
According to Intel specs, DIMM0, must always be populated.
This means that to run dualchannel with only 2 DIMM's, that you must check your manual and look carefully which slot is for DIMM0.
According to the manual, it will be slot DIMM1 on your board, but watch out, this is not the slot closest to cpu, on current MSI P55 boards, (CD-53, GD-41, GD-45, GD-55, GD-65, GD-80 and the Big Bang Trinergy), its the second slot from cpu.
Picture of P55 mainboard:
From a manual from a MSI P55 board:
So for dualchannel with 2 sticks, you must populate the black slots, DIMM1 and DIMM3 and for single channel with one stick DIMM1 most be used.
Please bear in mind that DIMM0 in Intel spec.sheets means DIMM1 on your board.
The link to technical sheet from intel about : i7 8xx cpu's
http://download.intel.com/design/processor/datashts/322164.pdf
A short quote with the relevant data:
Quote
Rules for Populating Memory Slots
In all modes, the frequency of system memory is the lowest frequency of all memory
modules placed in the system, as determined through the SPD registers on the
memory modules. The system memory controller supports one or two DIMM
connectors per channel for unbuffered DIMMs. For dual-channel modes, both channels
must have at least one DIMM connector populated and for single-channel mode only a
single-channel may have one or more DIMM connectors populated.
Note: DIMM0 must always be populated within any memory configuration. DIMM0 is the
furthest DIMM within a channel and is identified by the CS#[1:0], ODT[1:0], and
CKE[1:0] signals.
For more info, please read datasheet
Also, let me remind you that this goes for ALL P55 boards out there, its not just an MSI thing.
This has to do with the fact that the memorycontroller now sits on die on the Lynnfield cpu's.
Im hoping to end the debate, like I had (and I was wrong), about the fact that you should be able to use any channel, like you could on the S775 boards, you just cant anymore.
Update 26 december 2009:
Running all 4 DIMM slots with memorysticks
It seems that a lot of people are having problems running with all memoryslots occupied, e.g. not booting, BSOD and other crazy stuff.
If you have such problems try the following first, before running back to the store to swap stuff out.
- Raise Vdimm to 1.65V, its still a save voltage for the board and this way the memory gets a little more power and in 99% of the cases, this will solve the issue.
- Try booting/installing with one stick first in DIMM1 on the board (see above).
- If it boots/installs, let it go all the way till windows is done.
- Turn off pc and add a second DIMM in DIMM slot 3, restart and let i boot all the way again in windows till its done.
- Do the same again for DIMM2 and last DIMM4.
We know its a bit of a hassle, but it worked for a lot of people, so be sure to try this before anything else.
And again, its not just an MSI thing, there are more manufacturers out there with the same issues, this also has to do with the fact the memorycontroller now sits on die with cpu.
I'll edit if new boards come out.

What's the right way to delete an entire backup ?

I've had two Macs doing wireless Time Machine backups to one Time Capsule.
Question: I got rid of one Mac, and want to delete its backup entirely (but leave the other computer's backups untouched). What's the right way to do it?

Bob Timmons wrote:
Jespes, welcome to the discussions!
Open your hard drive. Your Time Capsule icon should appear under the SHARED heading.
Click on the Time Capsule and a folder will appear to the right.
Double click the folder and you should see a xxxxxx.sparsebundle file for each computer that has been backing up.
Click on the xxxxx.sparsebundle file that you want to delete to highlight it and then click the gear shaped icon just above. Select Move to Trash. (Do not drag the file to the Trash as this will not work).
Be careful, as the file will be deleted instantly and you will not be able to retrieve it.
many thanks!

Being Nice to your Layout manager - Is this the right way?

Ive written a custom component that basically provides multi-line text wrapping and a few other nice things.
I had a bit of trouble when I came to implementing
getPreferredSize() getMinimumSize() This is because ideally, I'd like the component to use as much space horizontally as possible, whilst using only as much vertical space as necessary.
To do this, I used the parents width as the minimum horizontal size. This then allowed me to work out the height.
Question is - is that the right way to do it? Other than that, I just cant think of a way to get the width I need when the component is first added to its container.
Cheers for any input,
Dave

If you want it to use as much horizontal space as possible, that means you want its width to be equal to its container's width (perhaps minus a bit for borders or something). So in that case you would have to set its minimum width to that number, and that's exactly what you did. There could be other ways to do it, but yours seems perfectly fine to me.

How to create a custom panel in the right way (without having an empty panel in the file info) ?

Hi Everyone
My name is Daté.
I'm working in the fashion industry as a designer and Design consultant to help fashion brands improving the design workflow by using Adobe softwares and especially Illustrator.
I'm not a developper, but i'm very interested about the possibility to introduce xmp technology to provide more DAM workflows in the fashion industry.
Fashion designers produce a lot of graphical objects in illustrator or Photoshop. Unfortunately they are faced to a big challenge which is about how to manage, search, classify and get this files faster. Of course PDM system or PLM system are used in the Fashion industry to manage data, but for many companies, implemanting this kind of database is very complex.
When i look at what you can do with xmp, it seems to be an interesting way of managing design files, then i started to follow Adobe instruction to try to build a custom panel.
The main idea is to (Theory) :
create custom panels used by fashion designers to classify their design files.
Use Adobe Bridge to search files, create smart collection to make basic reports in pdf and slideshows
Find someone to make a script able to export metadata in xml files
Use indesign and the xml file to generate automatically catalogues or technical sheets based on xmp values
I have created a custom panel by using the generic panel provided by Adobe and i have modified the fields to feet with the terms used in the fashion industry and it works well.
But unfortunately, when i try to create my own custom panel from scratch with Flashbuilder (4.6) and the Adobe CSExtensionBuilder_2 (Trial version), it doesn't work!
Here is the process :
I have installed flashbuilder 4.6
I have download the XMP Fileinfo SDK 5.1 and placed the com.adobe.xmp.sdk.fileinfo_fb4_1.1.0.jar in C:\Program Files (x86)\Adobe\Adobe Flash Builder 4.6\eclipse\plugins
In Flashbuilder, i have created a new project and select xmp Custom panel
The new project is created in flashbuilder with a field with A BASIC Description Field
To generate the panel, right click the project folder and select xmp / Publish Custom Panel
The panel is automatically generated in the following folder : C:\Users\AppData\Roaming\Adobe\XMP\custom file info panels\3.0\panels
Go to illustrator, Open the file Info
The panel appears empty
The others panel are also empty
The panel is created and automatically placed in the right folder, but when you open it in Illustrator by selecting the File Info option in the File Menu, this custom panel appears empty!!! (only the title of the tab is displayed). This panel also prevent the other panels to be displayed.
When you delete this custom panels from the folder C:\Users\AppData\Roaming\Adobe\XMP\custom file info panels\3.0\panels and go back to the File Info, the other panels display their content properly.
I also try to use the plugin XMP Namespace designer to create my own namespace. this plugin is also able to generate a custom panel, but this one also appears empty in AI or Photoshop.
I try to follow the process described in Adobe xmp documentation many times, but it didn't works.
It seems that many peaople have this issue, but i dodn't find a solution in the forum.
I try to create a trust file (cfg), but it didn't work.
It would be so kind if you can help me to understand why i can't create a custom panel normally and how to do it in the right way.
Thanks a lot for your help,
Best regards,
Daté

Hi Sunil,
After many trial, i realize the problem was not coming from the trust file, but from the way i have created the custom panel.
There is 2 different ways, the first described below is not working whereas the second is fine :
METHOD 1 :
I have downloaded the XMP-Fileinfo-SDK-CS6
In the XMP-Fileinfo-SDK-CS6 folder, i copied the com.adobe.xmp.sdk.fileinfo_fb4x_1.2.0.jar plugin from the Tools folder and i pasted it in the plugind folder of Flashbuilder 4.6
The plugin install an XMP project
In Flashbuilder 4.6 i have created a new project (File / New /Project /XMP/XMP Custom Panel)
A new xmp project is created in flashbuilder.
You can publish this project by right clicking the root folder and selecting XMP / Publish Custom Panel
The custom file info panel is automatically published in the right location which is on Mac : /Users/UserName/Library/Application Support/Adobe/XMP/Custom File Info Panels/3.0 or /Users/UserName/Library/Application Support/Adobe/XMP/Custom File Info Panels/4.0
Despite the publication of the custom file info panel and the creation of a trust file in the following location : "/Library/Application Support/Macromedia/FlashPlayerTrust", the panel is blank in Illustrator.
I try this way several times, with no good results.
METHOD 2 :
I have installed Adobe CSExtensionBuilder 2.1 in Flash Builder
In FlashBuilder i have created a new project (File / New /Project /Adobe Creative Suite Extension Builder/XMP Fileinfo Panel Project)
As the system display a warning about the version of the sdk to use to create correctly a custom file info, I changed the sdk to sdk3.5A
The warning message is : "XMP FileInfo Panel Projects must be built with Flex 3.3, 3.4 or 3.5 SDK. Building with Flex 4.6.0 SDK may result in runtime errors"
When i publish this File info panel project (right click the root folder and select Run as / Adobe illustrator), the panel is published correctly.
The last step is to create the trust file to display the fields in the panel and everything is working fine in Illustrator.
The second method seems to be the right way.
For sure something is missing in the first method, and i don't understand the difference between the XMP Custom Panel Project and the XMP Fileinfo Panel Project. Maybe you can explain it to me.
So what is the best solution ? the right sdk to use acording to the creative suite (the system asks to use 3.3 or 3.5 sdk for custom panels, so why ?)
I'm agree with Pedro, a step by step tutorial about this will help a lot of peaople, because it's not so easy to understand!!!
Sunil, as you belong to the staff team, can you tell me if there is :
A plugin or a software capable to extract the XMP from llustrator files to generate XML workflows in Indesign to create catalogues
A plugin to allow indesign to get custom XMP in live caption
A plugin to allow Bridge to get custom XMP in the Outputmode to make pdf or web galeries from a smart collection
How can you print the XMP data with the thumbnail of the file ?
Thanks a lot for your reply.

What is the right way to display a table in Java web dynpro using a node.

Hi experts,
I am trying to show a node of cardinality 0...n as a table in an adobe form in Java web dynpro. But its not showing it properly. Can anybody please tell me what is the right way to display a table on adobe form using a node of cardinality 0...n or 1...n in Java Webdynpro. In ABAP webdynpro, we can drag and drop a node of cardianlity 0...n or 1...n to show as a table and it works fine. Is the same possible in Java webdynpro also. Please help.
Thanks and Regards.

Please refer to my post.. you will get the answer
Dynamic Table - same data repeating in all rows
Special care should be taken in designing the context for table attribute.
The attribute type singletone also plays a important role. I have this doubt from the beginning when you have reported this problem for the first time but finally you marked it as solved so i thought there might be some other issues but again when you reported that again i did some analysis.
Now coming to final solution :
For designing a table in adobe interactive form you have consider following
You have to design the view context upto three level, I am explaining you the properties
PDFDataSource (Parent Level1) - Cardinality 1:1 - Signetone -True - This is assigned to datasource
TableList (Parent Level2) - Cardinality (1:1) - Signetone -True
TableWrapper(Parent Level3) - Cardinality (0:n) - Signetone -True
TableData (Parent Level4) - Cardinality (0:1) - Signetone - false (This is the main point)
Then under TableData value node, you have to put all your table attributes.
This Value Node name can be anything but hierarchy should be same as I have mentioned above.
Please try out these steps and get back to me if you have any doubt.

Photos not the right way round

I imported loads of photos from my digital camera onto my mac, then flipped them the right way in preview.
I've just imported them to iphoto, and they all seem the right way up but when uploading to my webspace or emailing, although they look like they are the right way up, they are infact still landscape when they should be portrait... any thoughts why?!

You can export them to the Desktop and then reimport. The new file will be naturally oriented correctly and should work in any application OK. You can check it out by seeing if there's been a subfolder created in the Modified folder that is the same name as the one in the Originals folder. There should not be one. Once reimported you can delete the first set. You can make it easier by assembling them into a single roll and delete from within iPhoto.
Do you Twango?
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.

The "right" way to handle multiple devices, accounts and the cloud?

Perhaps a bit premature, but I figure it's never too early to start planning.
Here's our current setup - I currently have four iDevices in the faily (three iPhones and one iPod Touch. All are syncing to the same Mac Mini, albeit with different logins (and different iTunes store ids). All four of these are kept in sync via Home Sharing so we have access to the music/apps/etc acquired by the others.
Enter the iCloud - how does this fit in? What's the *right* way to do this?
I can see two options:
1)     Continue to utilize four iTunes store ids, sync them via Home Sharing and add four iClouds
     Advantages
          totally independent devices, users, etc.
     Disadvantages
          must pay for four "iTunes Match" services to access non-iTunes music on each of the four devices
          will iTunes-purchased music automaticaly sync to iCloud if it is shared via Home Sharing (or only by the original purchaser)?
2)     Use one iTunes Store id for all iDevices
     Advantages
          single point of acquisition and distribution for all devices
     Disadvantages
          need to find a way to merge IDs (is this even possible?)
Are there other advantages/disadvantages to these options? Are there other options? What's the easiest to set up and support? Any other thoughts?
Thanks in advance for your input.

Well it seems like the first thing you should do is consolidate your iTunes libraries so that you don't have 4 copies of everything, one for each user logged in to your Mac Mini. How you do that is consolidate all 4 iTunes folders to one folder located in the /Users/Shared/ folder and update each of your iTunes to point to that folder accordingly. That way you have one iTunes library, only one copy of your media, but accessible from multiple users.
One caveat is that if somebody is logged on and has iTunes open, you can't fast switch to another user and open iTunes. Apple made it so that only one user and one instance of iTunes can open a iTunes library at a time.
For your iTunes match situation, it does sound like you would be much better off sharing a single Apple ID with one iTunes Match. For consolidating, make sure you have everything everybody has shared via Home Sharing to the main account you'd like to move over to, and then simply go to each device Settings, Store, and the sign out of the original Apple ID and logon using the shared main Apple ID. I just looked at it and the automatic downloading is already live in iOS! You can specify if you want to do music, apps, and books separately in case you may want to automatically download music but not apps or books.

What's the "right" way to create a News list in CQ5.4?

Hey folks,
I'm a brand new CQ developer and, though I've done a lot of reading, I'm still in the dark on how to do a few things.
I'm currently working on a corporate website, and I need to build a News page. Each article contains a title and rich text (possibly including embedded images, videos, etc...), and the News page itself should display a paginated list of recent article summaries (with "read full article" links). I also need to show the two or three most recent article summaries on the site's front page, under a News heading.
I thought there'd be a pre-built component to cover this case, since most corporate sites include a News page of some sort, but I haven't found one. Am I missing it? I looked into the Blog page template, but I think that adapting that may be overkill.
I think that the right way to do this would be to build a News component with a Title and Rich Text field in the edit dialog. New articles could be created by dropping these components into the parsys of the News page. I could then create both a .html and a .summary view for the components and use a customized List component to display the summary list on the front page. Am I on the right track here, or am I overcomplicating it?
Thanks!

Hi,
The "right" way of building any list-like component is to extend the existing List component.
That is referenced in this documentation page:
http://dev.day.com/docs/en/cq/current/wcm/default_components.html#List
You can find it under /libs/foundation/components/lists
To create, for example, a 'News List' component, just create a new component under your /apps/myproject/components, setting 'foundation/components/list' as sling:resourceSuperType ans add your custom script to display each news item. see also [1]
That way you canprovide more renderers to be used around your site(s)
[1] - http://dev.day.com/docs/en/cq/current/developing/components.html#Developing%20a%20new%20co mponent%20by%20adapting%20an%20existing%20%20%20%20%20component
Hope this helps,

That's something I just did successfully one hour ago...
I suppose your are in the 'folder' view with full folder tree, not in the 'My folder' view which only shows the lower subfolder level recorded in the database.
Do you try to move a folder with its subfolders ?

What is the right way to connect the adapter to my macbook when charging?

what is the right way to connect the adapter to my macbook when charging.
is it connect the magsafe connector first before plugging the adapter to the outlet? or the way around? or both ways will do?
what if i'm using a surge protection with a on/off button, can I just turn the surge protector extension on and off without disconnecting the magsafe connector and adapter plug from my laptop when i'm not using it?
thank you very much

If there is any arcing it may be because the adapter is dirty. It is best to plug in the wall wart then attach the magsafe to the MacBook. As GfulDedFan mentioned this reduces the chance of power surging the MacBook. I have done mine this way since he day I bought it and have never had an arc. I keep it clean to reduce the chance of this happening. The following will help in the care of your supply.

[Solved]Bash:Manipulating arrays of paths? the right way or not?

Note: Refer to the following posts for better solutions and/or alternatives.
This is a mock segment of a script I'm writting and I need to know if I'm doing it the correct way or at least in a proper bash way...
the following works but will it always parse in a sorted manner. I have a set of directories that are named by date in the YYYY-MM-DD (International) format and want to be sure that they will always be treated as directory paths even when special characters "\n,\t,\s ...etc" are encountered in the path. The number of these directories changes and is compared to a set NUM-ber variable and when there are more than the set number the oldest ones are removed which brings a second question. Being dated as YYYY-MM-DD they sort from oldest to newest(lexicographical order) but do they always and is this the right way to deal with elements in an array separated by nulls? Any Comments or suggestions would be appreciated as I'm learning bash for the time being (perl is next) and gathered this from bits and peices on verious wikis and forums. I basically want know if this a correct approach to the subject of extracting and performing actions on elements of an array that are directory paths.
#!/bin/bash
oifs="$IFS"
IFS=$'\0'
DIRTREE=(/path/to/dated/directories/[0-9][0-9][0-9][0-9]-[0-9][0-9]-[0-9][0-9]/)
NUM=5
HOWMANYMORE=$(echo $(( ${#DIRTREE[@]} - $NUM )))
if (( ${#DIRTREE[@]} > $NUM )) ; then
rm -rv "${DIRTREE[@]:0:$HOWMANYMORE}"
fi
IFS="$oifs"
Note:I have tested this for those wondering

This works as really well, however, in my case I still need the other sets in separate arrays for other purposes in my personal script so I adapted the approach a little and got this which uses the array+=(foo) syntax properly now. I was aware of this feature in bash arrays and experimented with it but had no success adding elements from other arrays until you demonstrated it in your example by adding them though a "for loop" and doing the arithmetic there... My current one now is very similar...I'm not sure how to reduce it further if possible but I need the other arrays as I do something completely different with them:
#!/bin/bash
NUM=10

CT1=$(( ${#set1[@]} - NUM ))
CT2=$(( ${#set2[@]} - NUM ))
CT3=$(( ${#set3[@]} - NUM ))
for X in "${set1[@]:0:$CT1}" "${set2[@]:0:$CT2}" "${set3[@]:0:$CT3}"
do
combined+=("$X")
done
for
for Xdirs in "${combined[@]}"
do
rm -rv "$Xdirs"
done
I'm considering changing the title of this thread as it reveals a little more than I originally expected to go over and provides some pitfalls as well as ways to approach array manipulation which can be applied to wide range of uses in bash scripting.
