Best Method for Destroying Data on the Drive Before it Goes Back to Apple

As the subject suggests....any ideas....i'd like to 'shred' the whole drive and clean install without any personal info on it.

Run Disk Utility from the installation DVD and erase the drive with the option to write zeros. Once is fine although if you're paranoid you can choose a multiple pass option.
Also, I would subsequently install Mac OS X on to so you can start it up if required.

Best method for plotting data array?

I am reading data from a Delta Motion controller and writing that data to an array in my vb.NET program. The data is not time stamped but I know what the sampling interval is (0.001s). I want to take that data and plot it on my Waveform Graph. What is the best method for doing this? I'm sure this is simple, but I'm new to MS and LV.
Private Sub btnRampUpA_Click(sender As Object, e As EventArgs) Handles btnRampUpA.Click
Dim Axis0ActualPrsData() As Single = New Single(4096) {} 'Create array for data from the RMC controller to be read into
Dim Axis0Actual() As AnalogWaveform(Of Single)
If RMC.IsConnected(PingType.Ping) = True Then 'Check to make sure comms to RMC is good before trying to read data from it
Try
RMC.ReadFFile(FileNumber150.fn150Plot0StaticUA0, 112, Axis0ActualPrsData, 0, 4095) 'read the plot data where sample period = 0.001
Catch ex As ReadWriteFailedException
MessageBox.Show("Unable to read plot data from the RMC. " & ex.Message)
End Try
End If
End Sub
Thank you

PlotYAppend appears to be the answer according to the white page, although I don't have it working as of yet. Can someone confirm?

What is the best approach for transferring DAT to Hard Drive?

Hi,
I've got 10 60 min DATS of my 1970s rock band transferred from live reel to reel recording of gigs. I want to get rid of the DAT machine on Ebay and before I do get these DATS transferred for storage on CDs or DVDs.
I have an external hard drive to transfer to before burning to disc.
Does it make sense to use Logic Pro to transfer the DATS through the computer to the hard drive? Or is there a better / easier / faster way to do it?
I'll want to go back and find songs later and use Logic Pro to EQ and mix them onto a CD by track at some point.
Each DAT is 60 minutes worth of material and ideally I'd like to be able to run through the transfer and mark where songs start as the "in between" stuff is there also.
Thanks,
Bob

Hey, thanks for the reply.
Few more comments....
Could you suggest a Mac stereo editor/recorder.
What is s/pdif? I'm new to computer recording.
Slave recorder to the DAT....I'm hooking the DAT into the iMac through an interface...is this what you mean?
Got you on separate recordings....I want to do that later...Just get the whole tape onto the hard drive then onto a CD or DVD. When I have more time I'll run through and find songs, etc.
Again, thanks,
Bob

Best method for passing data between nested components

I have a fairly good sized Flex application (if it was
stuffed all into one file--which it used to be--it would be about
3-4k lines of code). I have since started breaking it up into
components and abstracting logic to make it easier to write,
manage, and develop.
The biggest thing that I'm running into is figuring out a way
to pass data between components. Now, I know how to write and use
custom events, so that you dispatch events up the chain of
components, but it seems like that only works one way (bottom-up).
I also know how to make public variables/functions inside the
component and then the caller can just assign that variable or call
that function.
Let's say that I have the following chain of components:
Component A
--Component B
-- -- Component C
-- -- -- Component D
What is the best way to pass data between A and D (in both
directions)?
If I use an event to pass from D to A, it seems as though I
have to write event code in each of the components and do the
bubbling up manually. What I'm really stuck on though, is how to
get data from A to D.
I have a remote object in Component A that goes out and gets
some data from the server, and most all of the other components all
rely on whatever was returned -- so what is the best way to be able
to "share" data between all components? I don't want to have to
pass a variable through B and C just so that D can get it, but I
also don't want to make D go and request the information itself. B
and C might not need the data, so it seems stupid to have to make
it be aware of it.
Any ideas? I hope that my explanation is clear enough...
Thanks.

Peter (or anyone else)...
To take this example to the next (albeit parallel) level, how
would you go about creating a class that will let you just
capture/dispatch local data changes? Following along my original
example (Components A-D),let's say that we have this component
architecture:
Component A
--Component B
-- -- Component C
-- -- -- Component D
-- -- Component E
-- -- Comonnent F
How would we go about creating a dispatch scheme for getting
data between Component C and E/F? Maybe in Component C the user
picks a username from a combo box. That selection will drive some
changes in Component E (like triggering a new screen to appear
based on the user). There are no remote methods at play with this
example, just a simple update of a username that's all contained
within the Flex app.
I tried mimicking the technique that we used for the
RemoteObject methods, but things are a bit different this time
around because we're not making a trip to the server. I just want
to be able to register Component E to listen for an event that
would indicate that some data has changed.
Now, once again, I know that I can bubble that information up
to A and then back down to E, but that's sloppy... There has to be
a similar approach to broadcasting events across the entire
application, right?
Here's what I started to come up with so far:
[Event(name="selectUsername", type="CustomEvent")]
public class LocalData extends EventDispatcher
private static var _self:LocalData;
// Constructor
public function LocalData() {
// ?? does anything go here ??
// Returns the singleton instance of this class.
public static function getInstance():LocalData {
if( _self == null ) {
_self = new LocalData();
return _self;
// public method that can be called to dispatch the event.
public static function selectUsername(userObj:Object):void {
dispatchEvent(new CustomEvent(userObj, "selectUsername"));
Then, in the component that wants to dispatch the event, we
do this:
LocalData.selectUsername([some object]);
And in the component that wants to listen for the event:
LocalData.getInstance().addEventListener("selectUsername",
selectUsername_Result);
public function selectUsername_Result(e:CustomEvent):void {
// handle results here
The problem with this is that when I go to compile it, it
doesn't like my use of "dispatchEvent" inside that public static
method. Tells me, "Call to possibly undefined method
"dispatchEvent". Huh? Why would it be undefined?
Does it make sense with where I'm going?
Any help is greatly appreciated.
Thanks!

Best Method for Saving Data to File?

Hi,
We're using labVIEW 2009 to acquire data from our instrument. In the past we have used the "write to labview measurement file" express configuration tool to save data to a file. However we had some issues with our VI - occasionally we would lose data or column headers somewhat erratically and were never able to sort out the problem. We would like to rewrite our VI with the best possible solution.
Here's a summary of what we would like to do:
Save 30 variables at a rate of roughly 1 Hz. We would like one set of column headers per file so that the data can be easily imported into labVIEW with the variable names intact. We will be collecting data continuously, so we would like to divide the data into 3-4 files per day. Ideally, the program to start new files at the same times from day to day and the filename could be configured to include the date and time/file number.
I am hoping that users can provide a little feedback about methods that were most successful and reliable. From what I have read there are a few different ways to do this (express VI, tdms, "write to text file"). Any thoughts or relevant examples would be quite useful for us!
Thanks for your help!

Meg T wrote:
Is it correct to say that in your method, the indexing results in building up the data into one large array of data before saving it to the file with the column headers and filenames appended? If we are writing data at 1Hz for 6 hours of time, will we run into an issue being able to store all the data?
Yes the indexing will build up one large array. If this is a problem due to array size and memory, you will have to write more often. You can write every second, that should not be a problem. You should still write the column names to the file first, and have the append input set to False (or nothing wired in since the default is false). This will create a new file with the headers only. Then the data write has a True wired in so that the append takes place. If running for 6 hours and gathering data once per second, your array will contain 36,006 rows of data. I'm not sure if that would cause a memory problem or not.
Meg T wrote:
it also seems difficult to incorporate headers into express VI if you are writing the data continuously as a part of a loop with the "append" option.
If you write the headers before the loop as I have shown, and use append inside the loop, you will not have problems.

Best method for transferring data from one database to another?

There is an 8i database I have to deal with on a regular basis. Besides being completely outdated and unsupported, in my opinion the database has not been well-maintained--for a table with 25 million records, should ‘select count(*) from table;’ take 5 minutes to run? I don’t really know, but that seems long to me. Many complex queries (most including only tables with less than a million records) take a ridiculously long time to run, to the point that I can’t even run some of them.
I am not the DBA; I don't have the authority to fiddle with the database (nor would I feel comfortable doing that), and the powers that be will not put effort into improving functionality of this database due to an alleged plan to update/replace it within the next year. However, in the mean time, I still have to get data out of this database on a regular basis.
I have XE 10g installed on my local machine, and I have set up a database link in it to the 8i database. I have found that I can pull in basic data (simple queries) from the 8i database into tables in my XE database (e.g. create table tbl1 as select data from tbl1@8idb) and then query those tables to get the information I need much, much faster (including creation of the tables). While this option does not allow me to create queries/reports that other people can run, it makes work I’m doing only for myself much faster.
What I’m wondering is, what is the best way to bring the information I need over to my database? I usually don’t need entire tables, and I can probably identify a number of key tables (or parts of tables) I need. What I’ve been doing up until now is writing CREATE TABLE statements on the fly, but then I end up forgetting what all I’ve done, and each time I want up-to-date data, I have to drop the tables and re-create them. It seems to me that there should be an easier way to do this than to copy and paste from a text document into SQL*Plus.
Does anyone have any suggestions for me on how best to do this?

Sorry, I guess I posted this in the wrong forum. I re-posted in the database-general forum.

Best method for exporting data???

Howdy!I am exporting data from my production Essbase databases every day. I have chosen to export "ALL" data, but have not been exporting it in column format. Would someone please comment on the pro's & con's of archiving data this way?TIAJR

Pros of exporting all data in column format:1. You can reaload a database quickly without calculation2. Using column format, you can use a load rule to load parts of the data3. If some of your data is created by unique calcs, you can recover it easier in case of a crashCons:1.You can end up with very large files(actually a lot of 2 gig files)2. It can take a long time depending on the size of your databases3. Exports prevent you from doing other things to the cube while exporting. Glenn [email protected]

What is the best method for writing Multicolumn List data to a text file?

I am trying to find the best method for writing the data from a multicolumn list to a text file. Say the list has 7 rows and 6 columns of data. I would like the final file to have the data resemble the Multicolumn List as closely as possible with or without column headers. A sample VI showing how to accomplish this would be greatly appreciated. I realize this is pretty basic stuff, but I can get the output to the file, but it comes out with duplicate data and I am on a time crunch hense my request for help.
Thank You,

What is the best method for saving files off of the hard drive?

I would like to save music files and photos somewhere other than my hard drive (eg. CDs, DVDs, zip disks). What is the best method for doing this?

It rather depends on how paranoid you are
External hard drives protect you from hard disk trouble on your machine.
Optical media (CD's, DVD's) protect you from trouble with magnetic disks - such as external hard drives and the HD in your machine. Optical disks are thought to be more reliable that magnetic disks for long term storage.
Off site back-ups will protect you from fire or theft at your home or office.
How paranoid are you? Personally everything is backed up across three diferent external HD's. And maybe twice a year I burn a copy of my photos onto DVDs and they go to a relative's house across town.

HT1229 what is the best method for using a iphoto with an external hard drive for greater capacity?

what is the best method for using a iphoto with an external hard drive for greater capacity?

Moving the iPhoto library is safe and simple - quit iPhoto and drag the iPhoto library intact as a single entity to the external drive - depress the option key and launch iPhoto using the "select library" option to point to the new location on the external drive - fully test it and then trash the old library on the internal drive (test one more time prior to emptying the trash)
And be sure that the External drive is formatted Mac OS extended (journaled) (iPhoto does not work with drives with other formats) and that it is always available prior to launching iPhoto
And backup soon and often - having your iPhoto library on an external drive is not a backup and if you are using Time Machine you need to check and be sure that TM is backing up your external drive

What is the best method for backing up photos in IPhoto?

I have over 10,000 photos in IPhoto and am looking for the best method for doing a backup (or an archive?). I'm now using ICloud and it appears it's just photo streaming and does not have storage capability. External hard drive, copying to a DVD, other suggestions?

Most Simple Back Up
Drag the iPhoto Library from your Pictures Folder to another Disk. This will make a copy on that disk.
Slightly more complex:
Use an app that will do incremental back ups. This is a very good way to work. The first time you run the back up the app will make a complete copy of the Library. Thereafter it will update the back up with the changes you have made. That makes subsequent back ups much faster. Many of these apps also have scheduling capabilities: So set it up and it will do the back up automatically. Examples of such apps: Chronosync or DejaVu . But are many others. Search on MacUpdate
My Routine
My Library lives on my iMac. It’s Backed up to two external hard disks every day. These disks are permanently attached to the iMac. These back ups run automatically. One is done by Time Machine, one is a bootable back up done by SuperDuper
It’s also backed up to a portable hard disk when ever new photos are added. This hard disk lives in my car. For security, this disk is password protected.
I have a second off-site back up at a relative’s house across town. That’s updated every 3 or 4 months.
My Photos are backed up online. There are many options: Flickr, Picasa, SmugMug etc. However, check the terms of your account carefully. While most sites have free uploading, you will often find that these uploads are limited in terms of the file size or the bandwidth you can use per month. For access that allows you to upload full size pics with no restrictions you may need to pay.
Every couple of months I test the back ups to make sure they are working correctly. It’s very easy to mis-configure a back up application, and the only way to protect against that is to do a trial restore.

Question: Best method for mounting drives at log-in time?

I would like to know what others consider the best method for mounting drives at log-in time is? I can see a few methods such as start-up items on the client, start-up items on the server to managed users and possibly a start-up script. One wrinkle in the scenario is that users can log-in directly to the server so the method should allow that to happen gracefully. Thanks in advance for your help.

Hi Bigsky,
You are asking some really fundamental questions that require quite a lot of explanation. Luckily Apple has some great documentation on their server software.
You will be able to find your answers here by diggin in a bit:

Best method for refreshing a component's data?

What's better when you want to refresh the content of an object? Should you just replace your JComponent with an entirely new one, or should you try to get access to the data and then remove the items and then re-add them.
In my example, I have a JTree and am not sure which would be the best method to use. Should I try to remove all the nodes, or sometimes I think it would be easier to just remove the tree component from my panel, create a new tree and re-populate it?
Thanks for any advice.

I created a new sequence in both projects that is 720x480, 4x3 (0.9), and what I do is just scale the timeline down so that it's letterboxed. Is this the best method for achieving this? Or would you do something else? I don't like the idea of scaling my timeline down in Premiere.
Hello.
As Jim so rightly points out above, you do not need to do anything.
Just use your normal 16:9 widescreen footage, and author as normal.
Your player will letterbox automatically when it is connected to a 4:3 screen in setup (just make sure "Pan & Scan" is not also there)
