Best way to sort (short of dragging each one)

With so many apps, sorthing them into a working order one-by-one is a bear, especially across multiple pages - many times the app stops on a page and I can't get it to go to the next page, then apps get displaced and it causes changes on another page and so on and so on...
Is there a better way to sort, maybe a master list of some sort, that I can access to set them in the order I want them to appear?

No such option exists - at the present time anyway.

Best way of sorting a Vector by member variable

I have a Vector of objects called Node. Each Node has various member variables, one of which is an integer called cost.
What would be the best way of sorting this vector in ascending order of cost?
I tried Bubble Sort but once the Vector starts getting big, it is SO slow.
Any help much appreciated.
Thanks,
Peter

Declare your Node like this:public class Node ... implements Comparable {
// your other code here
public int compareTo(Object o) {
Node otherNode = (Node)o;
return this.cost - otherNode.cost;
}That code provides a "natural ordering" for your Node class. Then to sort your Vector, just do this:Collections.sort(yourVector);I don't know what kind of sort that will do, but no doubt it will be better than your bubble sort.

What's the best way to sort query results?

Hello All,
I have a standard CRUD UI that now needs the results sorted, based on input from the UI. What's the best way to sort results by entity fields?
I'm familiar with the conventional Java methodology using a TreeSet and comparator. Is this the best route, does BDB JE offer more convenient or performant alternatives?
I looked through the documentation and saw how to change the indexes, but I'm just looking to change the order in the scope of the query.
If my application were an address book, the UI would be sortable, ascending and descending, by date added, first name, last name, etc. based on which column the user clicked on.
Thanks in advance,

Hi Steven,
Using standard Java collections is probably the best approach.
One thing that may be useful is to get a SortedMap (Primary or SecondaryIndex.sortedMap) for the case where you have an index sorted the way you want, and then copy the primary index into a TreeMap (with a comparator) for other cases. That way, you always have a SortedMap to work with, whether you're copying the index or not.
I haven't tried this myself, just a thought.

Best way to sort data from a file alphabetically

If I have a file as such:
FIRST_NAME|LAST_NAME
I want to display the data in alphabetical order by last name and by first name. what is the best way to do this? I found java.util.Arrays
but i thought that it might be best if i read the data into a linked list. I want to display it on a form, so that I can press a next and previous button. Next will show the next record in alphabetical order after the previous one(B->C) and previous would go (C->B)
thanks.

How about this:
Create a PersonRecord object, and have it implement Comparable.
import java.util.Comparator;
public class PersonRecord implements Comparable < PersonRecord >
    public static Comparator < PersonRecord > surnameComparator ()
        public int compare (PersonRecord pr1, PersonRecord pr2)
            return pr1.getSurname ().compareTo (pr2.getSurname ());
    public static Comparator < PersonRecord > nameComparator ()
        public int compare (PersonRecord pr1, PersonRecord pr2)
            return pr1.getName ().compareTo (pr2.getName ());
}See java.util.Comparator, java.lang.Comparable.
Then use Arrays.sort(List, Comparable) at your own discretion...
I've said enough; work that part out yourself.

What is the best way to sort an XML document in WLI 8.1?

I have the schema for the XML and I want to sort the data. What is the best way to do this?

I'm not sure if you want the result of the sorting to be a sorted XML document or a sorted object tree but anyway both XSLT and XQuery support sorting so you could use a Transformation control to execute an XQuery or XSLT transformation to sort the data. Another option (if you are not comfortable writing XQuery or XSLT) would be to use XmlBeans and programmatically sort the data. A word of warning though, these processes are quite memory intensive and if the XML document you are sorting is large (say over 10 MB) your server might run out of memory. In this case you might be better of just parsing the document with SAX and then sorting the result objects.

What is the best way for sorting?

Hi i have 1000 customers in the database. I need to display them in the combo box. combox is editable. As the user types the letters i need to filter and display the customer names. for example if the user types 'a' in the combox i have to display all the customer names that starts with 'a'. if the customer types 'as' then i have to display only names that start with 'as' in the combo box popup. for every key stroke i have to filter and display the customer names.
for this there are two approaches:-
1. for every key stroke go to database and retrieve the sorted results and display them. In this way sorting happens in the database.
2. pull all the customers into java once, cash them and sort them accordingly based on the key strokes. In this sorting happens in our java code.
few friends said that going to databse for every key stroke is expensive. I feel pulling all the customers at once and cashing them in java is not a good idea.
I am really confused. I need an expert suggestion. which way is best? why is it the best way? what are the pros and cons in both the ways. please help me.
Thanks in advance.

Thanks ejp but initially if the combo box is not empty. that means if he did not typed any letter i will be displaying all the names.No. That's the mistake. Don't do that. A combobox with 1000 or 5000 items is completely useless.Do it the way I said.
My problem is if there are 5000 customers then what? will it not create a performance issue.Of course it will. It will also create a major performance issue for the user.
However you seem to have missed something else. By populating the combobox with anything, you are already running a cache. No two ways about it, and no way to avoid it. So whatever you populate it with, and whenever you do it, all you have to do when the user types another keystroke is filter the combobox model to exclude everything that doesn't match the prefix he has typed. The issue of going back to the database doesn't even arise.

What is the best way to work on multiple songs in one long recording?

I often record the local open-mic nights and generally just leave logic recording the entire night so i end up with lots of songs/bands in one big recording.
What is the best way to work with such a recording? Is there a better way than just using the event marker when a new band plays?
Also once i get home id like to save each band to a separate project but i cant seem to find an easy way to do this?
Obviously each band needs a different mix hence needing separate projects? or am i missing a much better work method?
any help greatly appreciated!
many thanks

As for your second point, just do a "save as" new file name and cut and erase any unwanted audio from the arrange window (ie. the bits that aren't in the song you want separate). You can do this for as many songs as there are and create a different mix for each one no problem. You multiple select and drag all the regions to the beginning of the arrange window (make sure you do them at the same time so's they don't go out of synch. All the separate songs and mixes can be saved in the same project folder as the original audio files are stored in (the folder structure should be there already if you started a new logic project, so no need to change that.
I would think using markers so you know where each song begins during the show, and the above method after, would be a very good way of organizing things. You may want to stop actually recording between bands too though I expect you are already doing this.
Its really as easy as that. Sometimes things just are.

What is the best way to move an iPhoto library from one internal drive to another internal drive?

the drive where my iPhoto library is store is just about full. I have a second internal SSD that I'd like to move (not copy) the library to. What is the best way to do that and still ensure that iPhoto will access the library in its new location?

Just drag the iPhoto Library package from the one drive to the second disk. Launch iPhoto with the Option key held down and select the library in it's new location on the second disk. Once you're satisfied that it is working satisfactorliy you can delete the copy on the first disk.

What's the best way to load balance multiple protocols on one vserver?

Hi,
We have a CSM blade on a 6513, in bridge mode. I'm just wondering what is the best way to serve HTTP and HTTPS (or any two or more ports) from the same group of servers. As I see it, we have two options:
1. Don't set a port on the vserver, so it is load balancing "any" or "tcp". This is easy but I want to be sure there isn't a downside to this, other than the obvious security issue.
2. Create multiple vservers and point them at the same serverfarm. I tried this and I got some odd results with the health checks.
Any ideas? Thanks a lot.

you listed the only 2 options available.
The advantage of solution #2 is that you can apply specific config for each protocol ie: for HTTP you can turn 'persistent rebalance' if needed.
If you want to use specific probes [not icmp], it is also a good practice to create a different serverfarm for each protocol.
Like this, if the HTTP service goes down but not the server, you can still have other protocols loadbalanced.

Gilles.

What is the best way to operate 2 separate iphones on one computer

HI - HELP PLEASE.....
My wife has an iphone and an itunes account registered on her computer - i have just bought an iphone and i want to register it to the same computer, create and itunes account, but we want to keep out apps & music ect seperate - what is the best way of doing this? Thanks.
rb999

The best way is a matter of personal taste. The Apple support document How to use multiple iPods with one computer suggests a number of ways, each with their own pros & cons. For instance if you generally share one profile on the computer already, creating another just to support a different iTunes library may be inconvenient. Switching libraries within the same profile ought to be as easy as opening two different documents, but it isn't. If you have some cross over in your taste for music and apps you may find a shared library is actually easier to manage.
We don't have two iPhones in the family as yet but as I understand it each device can have separate settings for syncing calendars and contacts. For example my iPhone syncs these over the air with the Exchange server at work so if/when my wife gets an iPhone it would be easy to have hers sync to our computer.
If you go down the shared library route you can make sure your apps don't inadvertently merge by turning off Automatically sync new apps from the apps tab when you connect your device.
For media I use the sync with selected playlists method with a slight twist. Rather than regular playlists I set the grouping field to indicate which users should receive which tracks and create smart playlists based on the content of this field.
e.g.
"Alice's Tracks" is "Grouping contains Alice" + "Kind contains audio"
"Bob's Videos" is "Grouping contains Bob" + "Kind does not contain audio"
Tracks that both Alice & Bob want on their iPods have the grouping set to "Alice/Bob"
etc.
I currently manage our family's five iDevices using this system, each getting a different selection to suit their tastes and the capacity of their device. An advantage of using the grouping field is that it is stored in file tags (for non-wav audio files anyway) so that it is relatively easy to recreate the playlists should the iTunes library get trashed and need rebuilding. Also useful if you move files about manually as playlist membership is preserved when you delete & re-import the tracks.

Multicast Voice Chat - Best Way To Handle (Multicast /w more than one broadcaster)

Hello. Currently I am working on a multicast voice chat application. I am a bit new to the multicast scene and I could really use some help with how to go about the next stage of coding.
The plan is to make an application that allows 5 (expandable later) users to connect to each other through stratus and communicate using voice chat streams. Right now, I have been able to accomplish a typical broadcaster to receiver application, but I am not sure what the best way to go about adding multiple broadcasters is.
I can currently see two real choices. Assign each member in the group a number (or use the ID's) and then create an additional receiving stream for each member that connects, or create 5 differen't group specifiers basically making 5 different instances of the application with one broadcaster and 4 receivers.
If anyone can help me think of a better way, that would be great.
Also, is there a way to find out the total number of users in a group or to access their ID's?
Thanks.

Take a look at the 3 packages that start with "java.util.concurrent", and the methods of java.util.Collections that start "synchronized. . ." and you can probably find something that will work for your situation.

Best way to turn a looped region into one regular region.

Hello,
This is going to be a very easy question for someone to answer.
When I record a small part (say just a 2 bar lick) I then pull the end corner to loop it.
FANTASTIC.
But I would rather view it on the main window as one solid region, rather than seeing the little ''bite marks'' that make it look like an accordion, or a bunch of regions pushed together. To me, that looks messy.
I have yet to find a way to quickly turn it into one region. Would the best way really be to bounce in place, because merging or joining does not seem to work for loops.
Again, I'm sure it is something I'm missing here that it quite simple.
I'm still trying to get my logic legs and put my PT ones on hold for the time being.
Cheers.

Bounce in place.

Best way to sort a Table

Hi Gurus,
I'm using a EJB to read Data from a DB and write it into a Context Node "SourceNode" in my Component Controller.
In the View, I've got a Node "DisplayNode", which is not mapped to "SourceNode" and but is filled using a supplaymethod that uses WDCopyService to copy the content of "SourceNode" to "DisplayNode". In the View, I've got a Node "FilterNode" that holds the entered filter attributes and a Node "TempNode" for looping on the diffrent filter attributes.
So everytime filter attributes are entered, I reduce the content of "DisplayNode" and when the filter attributes are reseted, I copy back the hole "SourceNode" to "DisplayNode".
The question is, if there is a more efficient way to do this, since if my SourceNode hast got 10.000 an more entries, this gonna take long to filter and to reset filter.
Thanks in advance.
Helpful answers will be rewarded with points.

This is semi-related to my other post about the MINUS statement. The full query that I'm playing with can be viewed there.
Currently, two field of the table must be specified in the where clause of the query: a bank_account_id and a date range. There are 4 other fields that can be used to restrict the search results, but they are not expected to be a primary means of searching.
The anticipated number of records in the table at any given time is expected to be between 1 million and 1.5 million records spanning 50 bank accounts over a period of 3-6 months.
Currently the indexes that I have specify the bank account ID as the first field of every index followed by the fields in the order by clause (which include the date field).

Is there a best way of improving short lived process performance?

Hi,
Apart from setting the thread pooling option in adminui, cacheing the form templates, What other options are available for performance improvement ?
We tried setting the thread pool options and no much difference was found in response time.
Any info on this would be helpful.
