Best way to use multiple external harddrives?
Hey everyone
I want to ideally have a setup where I have 3-4 Harddrives attached to my macbook (1 firewire powered, the rest independently powered), but am nervous about power distribution and data transfer rates. Is there any sort of hub or external box that can help manage these drives better? I've heard that daisy chaining multiple drives is not a good idea.
Thanks
Well daisy chain firewire device is a lot more easier than back in the day you have to configure terminator and tiny jumper set up on each HD for specific SCSI ID.
So far I have daisy chained 3 device using fire wire :
macbook - external Lacie HD - external lightscribe DL dvd burner - Sony TRV camcorder, and no problem until now.
You can give firewire Hub a shot, but make sure it has its own power adapter for the power provided from macbook firewire port might not enough for fire that hub up.
Here is one of the unique hub that I wish to have if it comes in black like my macbook.:

What is the best way off using two external harddrives with timemachine?
Hi,
I have already searched the board but I am still not sure what the best way is to backup to two harddisk.
Here is what I want to achieve:
I have two identical external firewire drives. One is always stored at my parents house. I swap drives once a week +(not perfect, should be everyday but much better than nothing).+
Before TimeMachine I have used SuperDuper which made incremental backups on both disks.
Due to my "method" I never have both drives at home. So it will not work to clone the external disks.
Can I now simply swap the drives and TimeMachine will backup again on disk 2, what it has already backupped to disk 1? Like "catching up" the now missing backups for the last week?
Should I give the disks the same names or should I choose "change disk" everytime?
I appreciate any suggestions and experiences.
Best Regards
OlafHi Olaf,
Germany . . . hmmm, nice talking to you!
OK - We seem to have a lot in common. I used SuperDuper all the time too. Loved it. NEVER had a problem at all with it. Ever!
I use Carbon Copy Cloner now - it seems a bit erratic - sometimes fails, sometimes works, can't find the pattern.
But enough of that.
YES - Time Machine will do exactly what you want (or does for me, at least.)
I named the two drives the same name and bounced back and forth between them, Time Machining to each. Works PERFECTLY every time . . . BUT - you MUST go to TM preferences each time and click "change disk". Simply reclick the one it sees. This seems stupid - but it's worked every time for me so far. So this morning, I simple renamed one of the backup drives (from Finder). Simple renamed it.
Went directly to TM with the renamed disk - clicked "change disk" - he instantly "saw" the newly named disk - and it Time Machined perfectly to the "newly named" one. I didn't even have to re time machine the entire drive - it picked up perfectly and backed up only 50 meg, which is all I changed!
So Time Machine seems to work perfectly backing up to two hard drives, with either the same name, or different names - TM doesn't care. But you MUST simple click "change disk" each time.
Let me know how it works for you. It really does work for me!

Best way to use an external drive
Hello all,
I have several photos.
I also have three computers that I regularly use: my Windows PC, my Macbook Pro, and a very new iMac.
Rather than place all my photos on each computer... I thought I could place them on a Western Digital Passport portable ext. drive. Then somehow use the drive from computer to computer to edit/play with my photos.
How do I best use iPhoto 08 to do that? I'm not sure... do the photos have to be on the computer in order to make albums, libraries, folders, etc? Or are those things more of thumbnails that POINT to certain files?
Please help a newbie understand the best way to use his external drive.
Thanks for any and all help!Hello, and welcome, Theodore!
I must first say that I don't yet have iPhoto 8.
I do, however, have a lot of experience with external drives (I have two). I have a huge amount of music in iTunes, so I keep a copy of it on each external drive. Then, when I need to access my music , I turn on either external drive, up comes the External Drive symbol on my display, then I go over to my dock, and select iTunes. I must remember to first open up the External Drive BEFORE I open iTunes (or iPhoto). I then add or subtract music (or photos), edit, and work on my collection. When I'm finished, I just close the application, then select the Hard Drive symbol, and choose File/ Exit Hard Drive. Reach over and turn off my Hard Drive, and it's all good. I just always remember to open the Hard Drive FIRST, before opening the application.
The same would work for iPhoto. If you place iPhoto onto your external drive, you could probably use any of your computers to connect to it. I would suggest you think about backing up your external drive's contents with either another external drive (which was my choice), or other alternate storage methods.
I only have one PowerBook, not multiple computers, but, other than that, the situation's the same. You want to keep your iPhoto collection off your computers, and onto one external drive. I hope this information can be of some help to you.
All best wishes... Cea -
What is the best way to use two external displays at the same time?
One of my displays has HDMI, DVI, and VGA inputs. The other has VGA and DVI inputs.
MBP, early 2011
Mac OS X 10.6.7
2.4 GHz Intel Core i5Kappy is dead on correct about Bridge Mode as a requirement for the Time Capsule.
Do you know how to check to see if the Time Capsule is configured this way?
Next question.....you really should not try to have two wireless networks....one Arris and another Time Capsule.....unless it is absolutely necessary. Two wireless routers in close proximity can create wireless interference effects that can cause problems with either...or both...networks.
Best to turn off the wireless on one router to keep the chances of wireless interference between routers minimized.
Are both the Arris and Time Capsule providing wireless signals? -
Is there any way to use a External Harddrive and use it off there?
I want to know if the iPad can be done to use a portable external hard drive and put data onto there and transferred again back onto the iPad.
I want to save by not purchasing the 64gb model but just use the 16GB iPad and connect a much more storage hard drive.
Im mainly using this idea for me to transfer my photos clearing them on my SD card and back onto my external hard drive all with the help of the iPad.
+you can say im trying to make the iPad like a computer+

Trying to save files on "PC" side of Mac, using a FreeAgent external harddrive. I get the error message E:/not accessible access denied. Can I not use an external harddrive, if not, what is the best way to back up PC side of a Mac
Apple has really crappy NTFS read-only that does not always work. And it is probably a licensing issue.
Paragon Software is constantly being updated and supported with their NTFS for Mac OS X - they also have an HFS+ driver for Windows that works - Apple's HFS+ read-only driver for Boot Camp / Windows does not.
I keep seeing problems and lack of support for MacFUSE, that could change.

What is the best way to manage multiple ipods using the same itunes?
Hi Everyone
i am trying to manage three different ipods through the one Itunes, all with very different tastes, not sure if I am doing it the best or easiest way so does anybody have a simple solution on what you're supposed to do, to keep it all simple!
Cheers
LivIf you have created a new Windows user account you need to log out and then log back in with your original user name. By default each Windows profile will have an independent iTunes library.
If instead you managed to create a new library within the same profile. click the icon to start iTunes and immediately press and hold down the shift key, keep holding until asked to create or choose a library. Click Choose and navigte back to your original which should be at <User's Music>\iTunes.
Your question as posed was:
What is the best way to manage multiple iPods using the same iTunes {library}?
in which case Selected Playlists is probably the best approach. Simply create a playlist for each device, Alice's iPod, Bob's iPhone etc. and sync the device with the appropriate list.

Best Way to Aggregate Multiple Announcement Apps and Possibly External RSS Feed
Hello,
I have two separate announcement apps (one in sub-site A, and one is sub-site B). I am trying to create a webpart that will display content from both apps together.
I have tried to setup a CSWP and have been able to set the query to pull in the data (Although it shows expired announcements, which I would need to eliminate). Now, I am trying to customize the display of the CSWP, including the property mapping values
to display the announcement title (currently working with the URL as a link) and body (truncated like the announcement summary view if possible).
How can I get the body from the announcement to display? The 'body' field isn't listed as an option in the drop down list of mapping values. Do I need to toggle an option on the separate announcement apps, create a column, map a field, or some combination?
Also, I'd like to know if it is possible to add in an external RSS feed. Or, if there is a completely different way to approach and accomplish this, please let me know.
Thank youHi,
To display the “Body” field of Announcements list properly in Content Search Web Part, you can take a look at this blog about how to customize the display template for a good
start:

Best way to achieve multiple paths with quizzes using Captivate 6?
I’m looking for the best way to achieve multiple paths and quizzes using Captivate 6.
Here is the scenario: The learner watches general slides 1 – 3 and then chooses between Path A, Path B, or both paths combined. If they choose Path A then they watch the A portion only and take the A Quiz only. Same happens for Path B and for the two paths combined. The learner would only have to go one path to complete the course.
What I’m finding is Captivate only has one Quiz results page (even if you create two separate quizzes, it merges them). I was trying to avoid having three separate projects for the same module to keep it simple. I see if I have three separate projects I could use the Multi-SCO Packager to merge them for use on my Moodle LMS. But wait, I don't have the elearning suite, so I don't have access to the Multi-SCO Packager...
My question is: What is the best approach way to accomplish this goal? Any recommendations?
Message was edited by: austinginaCaptivate 6 has Branch Aware quizzing. Turn on that option in Quiz Settings and then your Quiz Results page should only show results for the branch your user visits.

I am moving from PC to Mac. My PC has two internal drives and I have a 3Tb external. What is best way to move the data from the internal drives to Mac and the best way to make the external drive read write without losing data
Paragon even has non-destriuctive conversion utility if you do want to change drive.
Hard to imagine using 3TB that isn't NTFS. Mac uses GPT for default partition type as well as HFS+

Does Adobe Reader for iOS have the ability to open inbedded links created with Acrobat Standard to additional PDF docs? If not, then what would be the best way to use these already created PDF's on an I Pad?
driddy61,
As of June 2014, none of the Adobe Reader mobile products support the hyperlink action for opening a separate PDF document.
Adobe Reader for iOS
Adobe Reader for Android
Adobe Reader Touch for Windows 8
In addition, the Reader mobile products do not open multiple windows/documents simultaneously, which would make the navigation between PDF documents nearly impossible. (Once a hyperlink takes you to a different PDF document, you have no way to go back to the original PDF document.)
The only Adobe Reader product that fulfills your department's requirements is Adobe Reader XI (mostly for Windows/Mac desktop/laptop computers). Acrobat Pro and Standard are paid products.
Because you are in search of a less expensive device for your department, you could get a Windows tablet instead of a Windows desktop/laptop computer. Microsoft Surface Pro (that you've mentioned in your previous reply) is just one example. You can also find other less expensive Windows tablets.
Tablets
However, please keep in mind that there are two different types of Windows tablets running two different operating systems.
(a) A Windows tablet with an Intel-based processor running Windows 8.1 Pro
Example: Surface Pro 3
You can install and run traditional desktop apps (e.g. Adobe Reader XI) and new Windows Store apps ("Modern" or "Metro-style" apps).
(b) A Windows tablet with an ARM-based processor running Windows RT 8.1
Example: Surface 2
You can only install and run Windows Store apps (e.g. Adobe Reader Touch) but not traditional desktop apps like Adobe Reader XI.
In general, type (b) tablets are more affordable than type (a) tablets. However, if you want to run Adobe Reader XI, you do need to check the technical specification of each tablet and make sure the following conditions are met.
Processor: Intel
Operating system: Windows 8/8.1 or Windows 8/8.1 Pro, not RT
Hope this helps you choose the right device for your department. Please let us know if you have any questions about system requirements or supported features in the Adobe Reader products. -
Best Practice for using multiple models
Hi Buddies,
Can u tell me the best practices for using multiple models in single WD application?
Means --> I am using 3 RFCs on single application for my function. Each time i am importing that RFC model under
WD --->Models and i did model binding seperately to Component Controller. Is this is the right way to impliment multiple models in single application ?It very much depends on your design, but One RFC per model is definitely a no no.
Refer to this document to understand how should you use the model in most efficient way.

Repost-Best way of using connection pooling
I am reposting this, seems best suitable in this category.
I am using Eclipse 3.1 along with Tomcat 5.0, MySQL 4.1, J2EE1.4. I could set up the JNDI Dataresource connection pooling and tested with small test servlet. Now thinking of having common methods for getting connection / closing / commiting ....etc.
I wrote following. [Please let me know whether it is correct way of doing it - as i am not very sure]
package common;
import java.sql.*;
import javax.sql.*;
import javax.naming.*;
import org.apache.log4j.Logger;
public final class connectionManager {
private static Logger logger = Logger.getLogger(common.connectionManager.class);
public connectionManager() {}
public static Connection getConn () throws NamingException, SQLException
//JNDI DataSource connection pooling
Connection conn = null;
try{
Context initContext = new InitialContext();
Context envContext = (Context)initContext.lookup("java:/comp/env");
DataSource ds = (DataSource)envContext.lookup("jdbc/TQ3DB");
conn = ds.getConnection();
}catch (NamingException ne) {
new GlobalExceptionHandler(logger, ne);
conn = null;
throw new NamingException();
}catch (SQLException e){
new GlobalExceptionHandler(logger, e);
conn = null;
throw new SQLException();
return conn;
}//getConnection
public static void commit(Connection conn) throws SQLException
conn.commit();
public static void rollback(Connection conn) throws SQLException
conn.rollback();
public static void setAutoCommit(Connection conn, boolean autoCommit)
throws SQLException
conn.setAutoCommit(autoCommit );
public static void closeConnection(Connection conn) throws SQLException{
if (conn != null) {
conn.close();
conn = null;
}//closeConnection
public static void closeResources(ResultSet oRS, PreparedStatement pstmt) throws SQLException
if (oRS != null) {
oRS.close();
oRS = null;
if (pstmt != null) {
pstmt.close();
pstmt = null;
} // closeResources
}//ConnectionManager
I am having a login form which submits user name and password. I am checking this against the database. Following is the servlet to do that.
package login;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.sql.*;
import common.*;
public class loginServlet extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)

}//doGet
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException,IOException{
String userId = request.getParameter("userId");
String password = request.getParameter("password");
** call a method to validate the password which will return the
** User Name for authorized users and null string for un-authorised.
String uName = validateUser(userId, password);
//if uName is null .. user is not authorized.
if (uName == null){
//redirect to jsp page with error message
RequestDispatcher rd =
getServletContext().getRequestDispatcher("/jsps/mainmenu.jsp");
if (rd != null){
rd.forward(request,response);
else{
// the user is valid - create a seesion for this user.
HttpSession userSession = request.getSession(true);
// put the user name session variable.
userSession.setAttribute("userName", uName);
//redirect to Main menu page
RequestDispatcher rd =
getServletContext().getRequestDispatcher("/jsps/mainmenu.jsp");
if (rd != null){
rd.forward(request,response);
}// end of doPost
private String validateUser(String userId, String password)
throws SQLException{
String returnVal = null;
connectionManager cm = new connectionManager();
Connection conn = null;
PreparedStatement pstmt = null;
ResultSet oRS = null;
try{
//get the connection
conn = cm.getConn ();
//get records from user table for this user id and password
String sQry = "SELECT user_login FROM user "
+ "where user_login = ? AND user_pwd = ? ";
pstmt = conn.prepareStatement(sQry);
pstmt.setString(1, userId);
pstmt.setString(2, password);
oRS = pstmt.executeQuery();
//check for record
if (oRS.next()) {
returnVal = oRS.getString("user_login");
}else {returnVal = null;}
}catch (Exception e){
returnVal = null;
}finally{
cm.closeResources(oRS, pstmt);
cm.closeConnection(conn);
return returnVal;
}// end of servlet class
But i am unable to compile it and i am also getting lots of warnings.
I am getting error at line
1)String uName = validateUser(userId, password);
Unhandled exception type SQLException loginServlet.java TQ3/WEB-INF/src/login line
Following warnings:
2)For loginServlet Declaration
The serializable class DBTest does not declare a static final serialVersionUID field of type long loginServlet.java
3)The static method getConn() from the type connectionManager should be accessed in a static way
4)The static method closeResources(ResultSet, PreparedStatement) from the type connectionManager should be accessed in a static way
5)The static method closeConnection(Connection) from the type connectionManager should be accessed in a static way
Definitely I am doing it wrong but exactly where? I am having very strong doubt the way i am using connections is not the correct way. Pls help me.

ManishaI am in a search of best way to use connection pooling. Initially was using simple JDBC call, then modified to JNDI, afterwards tried to have common class. Later came accross the idea of Singleton/Static. I wanted to have a common class which will handle all connection related issues and at the same time give good performance.
With due respect to all Java Gurus: i got all from web articles/tutorials/java forum etc. There is a long discussion regarding Singlet vs static in this forum. But finally got confused and could not figure out in my case which method shall i make use of, so tried both.
What I want is somebody pointing out flwas inside my 2 code snippets and guide me about which method shall i adopt in future.
Static way:
package common;
import java.sql.Connection;
import javax.sql.DataSource;
import java.sql.SQLException;
import javax.naming.InitialContext;
import javax.naming.NamingException;
public final class ConnectionManager_Static {
private static InitialContext ctx = null;
private static DataSource ds = null;
public ConnectionManager_Static(){ }
//as the staic method is updating static var i am synchonizing it
private static synchronized void getDatasource () throws NamingException, SQLException
if (ds == null){
ctx = new InitialContext();
ds = (DataSource)ctx.lookup("java:comp/env/jdbc/MySql");
//making getConnection() also static as it is not instance specific
public static Connection getConnection () throws NamingException, SQLException, Exception
Connection conn = null;
try{
if (ds == null) {getDatasource ();}
if (ds != null) {
conn = ds.getConnection();
}catch (Exception e){
throw new Exception("From ConnectionManager_Static",e);
return conn;
}//getConnection
}Singleton:
package common;
import java.sql.*;
import javax.sql.*;
import javax.naming.*;
public final class ConnectionManager_Singleton {
private static ConnectionManager_Singleton INSTANCE = null;
private DataSource datasource = null;
// Private constructor for singleton pattern
private ConnectionManager_Singleton() throws NamingException{
Context ctx = new InitialContext();
datasource = (DataSource)ctx.lookup("java:comp/env/jdbc/MySql");
//synchronized creator for multi-threading issues
//another if check to avoid multiple instantiation
private synchronized static void createInstance() throws NamingException{
if (INSTANCE == null) {
INSTANCE = new ConnectionManager_Singleton();
public static ConnectionManager_Singleton getInstance() throws NamingException {
if (INSTANCE == null) createInstance();
return INSTANCE;
public Connection getConnection() throws Exception
Connection con = null;
try{
con = datasource.getConnection();
}catch(Exception e){
throw new Exception("From connection manager singleton ", e);
return con;
}Sorry, It's becoming long.
Thanaks in advance,

Best Ways to Handle Multiple Users

My family shares one computer. We have on folder on the hard drive where we keep all our music files. I got an ipod and itunes and added some of the music to itunes and have pretty much used itunes for my music.
Now my girlfriend got an ipod and I am hoping to somehow keep her music away from mine so to speak. So that I can keep synching my ipod without adding a bunch of music I dont want.
Is there a way to handle this? So thankfull for any help!There is an apple article on this here:

What is the best way to use EJB modules with JAX-WS?
Hi.
I am doing a project that returns EAN13 encoded data to external java clients.
I think I need to use a webservice that send response, a webservice client that send the request, and other project that transforms a data to an EAN encoded data, returns it and store it in MySql database.
It is possible that I need to authenticate users for every request made.
-I have created a EJB module contained into Glassfish for the webservice
-I have created a Common Java project with 3 layers: Entities, bussines and data access layer for mysql database
-I have a project for the webservice client with JAX-WS ( is the best choice? or Would be better JAX-RPC? )
**How would you suggest me create the structure of the project with all the java power?*
**Could you help me with goods tutorial of design patterns about webservices using EJB and the best way for use databases for this kind of projects ( I have heard about JNDI, Hibernate, Session EJB, ... )?*
**Would be better use other EJB module instead of a Common java project that has classes?*
