Any software differences between new airport express and extreme?

I was wondering if there are any features or configuration differences between the two, such as configuring VPN passthrough.
The only difference I can see is using the USB for hard drive use.
Also, do you think the performance will be similar. I know the time capsule actually rated slower than the extreme even though they use similar hardware.

You can find all the differences between the AirPort Express and Extreme in this website > http://www.apple.com/compare-wifi-models/

Is there a performance difference between Automation Plug-ins and the scripting system?

We currently have a tool that, through the scripting system, merges and hides layers by layer groups, exports them, and then moves to the next layer group. There is some custom logic and channel merging that occasionally occurs in the merging of an individual layer group. These operations are occuring through the scripting system (actually, through C# making direct function calls through Photoshop), and there are some images where these operations take ~30-40 minutes to complete on very large images.
Is there a performance difference between doing the actions in this way as opposed to having these actions occur in an automation plug-in?
Thanks,

Thanks for the reply. I ended up just benchmarking the current implementation that we are using (which goes through DOM from all indications, I wasn't the original author of the code) and found that accessing each layer was taking upwards of 300 ms. I benchmarked iterating through the layers with PIUGetInfoByIndexIndex (in the Getter automation plug-in) and found that the first layer took ~300 ms, but the rest took ~1 ms. With that information, I decided that it was worthwhile rewriting the functionality in an Automation plug-in.

Difference between reverse proxy plugin and java web proxy server

Hello
Can anyone please let me know what exactly is the difference between the reverse proxy plugin available with java system web server and the
java web proxy server.
Thanks
Manik Gupta.

The features are very closely related. The most notable and obvious difference is that The Web Proxy Server reverse proxy makes use of a content cache, while the reverse proxy of the Web Server does not cache results.

Java.beans.Expression and inner classes

hello,
test.java
public class test
public class in
public in()
System.out.println("inner");
t.java
import java.beans.*;
class t
public static void main(String...args)
try {
      new Expression(test.in.class,"new",null).getValue ();                                   // prints nothing
      new Expression(new test().new in().getClass(),"new",null).getValue ();           // prints OK
catch ( Exception e )
        System.out.println();
}Why "test.in.class" prints nothing ?
Thank you

What do you want?? it should print if you have system out
System.out.println(new test().new in().getClass());
instead of new Expression(....)
o/p
inner
class package_name.Test$in

Performance Difference Between Dual 2.7 and Quad, and Logic Pro

I used to have a G5 DP 2.7 before it went bad and Apple offered me a Quad in exchange. I'd like to understand some details of the specs between these two computers and how they might translate with respect to running Logic Pro (which I'll get to in a minute)...
Listed below are the specs which I believe illustrate the significant differences between these two machines (this info is based on info gleaned from Macworld, since the specific specs of the DP 2.7 no longer appear on Apple's website):
Dual 2.7
(2x) 2.7 GHz, cache = 512K per processor, frontside bus speed = 1.35 GHz per processor
Quad
(4x) 2.5 GHz, cache = 2MB on-chip L2 per chip, frontside bus speed = 1.25 GHz per processor
So here's the link with Logic: it's become apparent of late that Logic Pro is not able to fully utilize the processing power of all 4 cores in the Quad. Reports are that performance tops out at 50% per processor, resulting in approx. 200% possible processing usage from the 4 cores in the Quad.
However, such a limitation in processor usage wasn't present in the DP 2.7.
So based on the information I've learned so far, it seems that the Quad and the DP 2.7 are almost equivalent in terms of processing power when running Logic Pro. Now, this is what I'm surmising, but, is this actually the case? At the end of the day, I'd like to know if the Quad indeed a more powerful computer than the DP 2.7 when running Logic Pro, or, did my exchange of DP 2.7 for the Quad constitute a "downgrade" of any proportion?

The only logical answer to Why Intels do and PPC don't is:
Apple want everybody to transition to their Intel boxes. The only way to do this is offer better performance in software tweaks for one system over the another, which begs the question what else will Apple do to software for PPC owners?
Having bought a Mac Pro, primerily for testing out certain software apz under Rosetta, I did a real time test between my 8GB RAM G5 Quad and my stock Mac Pro upgraded to 2GB RAM, batch processing 204 Canon 1DsMKII RAW files into 16-Bitt TIFFs. I put a thread on the Mac Pro forum here:
http://discussions.apple.com/thread.jspa?threadID=627916&tstart=15
I so wanted my Quad to squash the Intel invaded Mac, but results speak for themselves. The Mac Pro flattened the G5 Quad by over 23 minutes (it worked out as 1.7 times faster than the G5Quad).
If that's how it performs with 2GB RAM it's gonna really fly when I max it out. So, for musicians, I would imagine with the Quad core support for Intel Macs in Logic 7.2.2 makes a fairly straight forward decision. . .buy a Mac Pro and sell your PowerMac. More time composing less time waiting for renders (never used music software so if it doesn't render your composition place whatever it does do into the 'renders' slot )
P.S I hated, really hated having to say the Mac Pro toasted my G5 Quad, I so wanted the Intel to fall flat on it's aluminium as$, but it didn't. It's a quick machine. A very quick machine which toasted my Quad in real time tests using a universal Pro app from a 3rd Party (who would have no incentive to dumb down the PPC version as they sell their product to Windows, PPC OS X and Intel OS X)

Difference between Oracle Application Express and Oracle Forms/Reports

hi guys,
i have just use oracle apex to create some report generation tools through the web. know that this is what is known as html db in the past.
however, i have not really touch oracle forms and reports before, neither have i really seen how they work.. but soemhow i feel oracle report/forms seems to be more.. then this oracle apex.
it includes integration with web services, java and pl/sql .
but i still cant really figure out what is the actual general main difference ?
is it that for oracle forms there can be some programming logic inside , whereas for apex , it is just using what is available from what oracle provides ..
i am read oracle form white paper, but seriously, i am not a very web guy. it has alot of components that i am not familiar with.
so i hope you guys can just give me a more general rough idea.
regards,
Noob.

Hi, my .05$
... most Forms & Reports users will tend to be old installed base customers using applications developed many years ago in F&R such as insurance company cores and even banking cores. Going from client/server F&R6 to "web" F&R10g is costly as you have to license an application server and most likely need to migrate to recent versions of the DB in case the customer is still on oracle 8 (common occurrence). So many customers opt. to not migrate or to simply invest in new web enabled solutions.
Using the migration tool f&r installed base will have an easier job of migrating and at a price of whatever DB edition they are using and probably be able to do it with the same people who maintain their f&r systems provided they learn a bit about web technologies.
what might be interesting to see is performance perception of users on f&r vs. apex...
regards,
luis aranguren

Native SQL Performance Difference Between Hard-Coded Value and Parameter

Hi,
I have a native SQL (Oracle) query (fairly long & complex with a few sub-queries) that returns in under a second in both ODSI and using an external SQL tool. This query has a hard-coded value for a particular column, namely, a date column.
When I modify the ODSI function signature so that I pass in a parameter and then replace the hard-coded value in the native SQL with the appropriate parameter binding notation (i.e. '?'), the query takes much longer (2-30 seconds). The duration of the query depends on how many records are actually returned, so it must be running a separate query for each of the results (i.e. the more results returned, the longer the query takes to return).
What can I do to keep the duration of my ODSI query low while allowing for the parameter?

Difference between Web Dynpro Abap and Web Dynpro Java

Hi,
What is the difference between Web Dynpro Abap and Web Dynpro Java.
Thanks,
Suresh

hi suresh......
from the end point of view, the customer wont know whether the application is done by java or abap. only the programming language differs and nothing much more.

Differences between Java Virtual Machine and Java HotSpot ??

I am little bit confused between Java Virtual Machine and Java HotSpot.
My understanding is:
Java Virtual Machine is the environment to execute Java programs. I think I could understand this part.
However, the description says, "The Java HotSpot product line consists of a server-side and a client-side virtual machine that share the Java HotSpot runtime environment, but have different compilers suited to the different performance characteristics of clients and servers."
I am confused with server-side virtual machine. what is that?? Does it mean the environment to execute Java programs remotely through network?? For example, Java plug-in.?? Please advise.

Hotspot is a JVM.
Hotspot has different configuration settings. Some of those settings are better suited for a client application. Some are better suited to server applications.

What is difference between Managed Bean and Backing Bean?

What is difference between Managed Bean and Backing Bean? Please guide me how to create them and when to use them?
Please post sample for both beans.

Hi,
managed beans and backing beans are quite the same in that the Java object is managed by the JavaServer Faces framework. Manage in this respect means instantiation. The difference is that backing beans contain component "binding" references, which managed beans usually don't. Do backing beans are page specific versions of managed beans.
Managed beans are configured either in the faces-config.xml file, or using ADF Faces and ADFc, in the adfc-config.xml file

Huge performance differences between a map listener for a key and filter

Hi all,
I wanted to test different kind of map listener available in Coherence 3.3.1 as I would like to use it as an event bus. The result was that I found huge performance differences between them. In my use case, I have data which are time stamped so the full key of the data is the key which identifies its type and the time stamp. Unfortunately, when I had my map listener to the cache, I only know the type id but not the time stamp, thus I cannot add a listener for a key but for a filter which will test the value of the type id. When I launch my test, I got terrible performance results then I tried a listener for a key which gave me much better results but in my case I cannot use it.
Here are my results with a Dual Core of 2.13 GHz
1) Map Listener for a Filter
a) No Index
Create (data always added, the key is composed by the type id and the time stamp)
Cache.put
Test 1: Total 42094 millis, Avg 1052, Total Tries 40, Cache Size 80000
Cache.putAll
Test 2: Total 43860 millis, Avg 1096, Total Tries 40, Cache Size 80000
Update (data added then updated, the key is only composed by the type id)
Cache.put
Test 3: Total 56390 millis, Avg 1409, Total Tries 40, Cache Size 2000
Cache.putAll
Test 4: Total 51734 millis, Avg 1293, Total Tries 40, Cache Size 2000
b) With Index
Cache.put
Test 5: Total 39594 millis, Avg 989, Total Tries 40, Cache Size 80000
Cache.putAll
Test 6: Total 43313 millis, Avg 1082, Total Tries 40, Cache Size 80000
Update
Cache.put
Test 7: Total 55390 millis, Avg 1384, Total Tries 40, Cache Size 2000
Cache.putAll
Test 8: Total 51328 millis, Avg 1283, Total Tries 40, Cache Size 2000
2) Map Listener for a Key
Update
Cache.put
Test 9: Total 3937 millis, Avg 98, Total Tries 40, Cache Size 2000
Cache.putAll
Test 10: Total 1078 millis, Avg 26, Total Tries 40, Cache Size 2000
Please help me to find what is wrong with my code because for now it is unusable.

Nicolas

Hi Robert,
Indeed, only the Filter.evaluate(Object obj)
method is invoked, but the object passed to it is a
MapEvent.<< In fact, I do not need to implement EntryFilter to
get a MapEvent, I could get the same result (in my
last message) by writting
cache.addMapListener(listener, filter,
true)instead of
cache.addMapListener(listener, new
MapEventFilter(filter) filter, true)
I believe, when the MapEventFilter delegates to your filter it always passes a value object to your filter (old or new), meaning a value will be deserialized.
If you instead used your own filter, you could avoid deserializing the value which usually is much larger, and go to only the key object. This would of course only be noticeable if you indeed used a much heavier cached value class.
The hashCode() and equals() does not matter on
the filter class<< I'm not so sure since I noticed that these methods
were implemented in the EqualsFilter class, that they
are called at runtime and that the performance
results are better when you add them
That interests me... In what circumstances did you see them invoked? On the storage node before sending an event, or upon registering a filtered listener?
If the second, then I guess the listeners are stored in a hash-based map of collections keyed by a filter, and indeed that might be relevant as in that case it will cause less passes on the filter for multiple listeners with an equalling filter.
DataOutput.writeInt(int) writes 4 bytes.
ExternalizableHelper.writeInt(DataOutput, int) writes
1-5 bytes (or 1-6?), with numbers with small absolute
values consuming less bytes.Similar differences exist
for the long type as well, but your stamp attribute
probably will be a large number...<< I tried it but in my use case, I got the same
results. I guess that it must be interesting, if I
serialiaze/deserialiaze many more objects.
Also, if Coherence serializes an
ExternalizableLite object, it writes out its
class-name (except if it is a Coherence XmlBean). If
you define your key as an XmlBean, and add your class
into the classname cache configuration in
ExternalizableHelper.xml, then instead of the
classname, only an int will be written. This way you
can spare a large percentage of bandwidth consumed by
transferring your key instance as it has only a small
number of attributes. For the value object, it might
or might not be so relevant, considering that it will
probably contain many more attributes. However, in
case of a lite event, the value is not transferred at
all.<< I tried it too and in my use case, I noticed that
we get objects nearly twice lighter than an
ExternalizableLite object but it's slower to get
them. But it is very intersting to keep in mind, if
we would like to reduce the network traffic.
Yes, these are minor differences at the moment.
As for the performance of XMLBean, it is a hack, but you might try overriding the readExternal/writeExternal method with your own usual ExternalizableLite implementation stuff. That way you get the advantages of the xmlbean classname cache, and avoid its reflection-based operation, at the cost of having to extend XMLBean.
Also, sooner or later the TCMP protocol and the distributed cache storages will also support using PortableObject as a transmission format, which enables using your own classname resolution and allow you to omit the classname from your objects. Unfortunately, I don't know when it will be implemented.
>
But finally, I guess that I found the best solution
for my specific use case which is to use a map
listener for a key which has no time stamp, but since
the time stamp is never null, I had just to check
properly the time stamp in the equals method.
I would still recommend to use a separate key class, use a custom filter which accesses only the key and not the value, and if possible register a lite listener instead of a heavy one. Try it with a much heavier cached value class where the differences are more pronounced.
Best regards,
Robert

What is the diffrence between package javax.sql and java.sql

Is javax designed for J2EE?
And when to use package javax?

Hi,
What is the diffrence between package javax.sql and java.sql?The JDBC 2.0 & above API is comprised of two packages:
1.The java.sql package and
2.The javax.sql package.
java.sql provides features mostly related to client
side database functionalities where as the javax.sql
package, which adds server-side capabilities.
You automatically get both packages when you download the JavaTM 2 Platform, Standard Edition, Version 1.4 (J2SETM) or the JavaTM 2, Platform Enterprise Edition, Version 1.3 (J2EETM).
For further information on this please visit our website at http://java.sun.com/j2se/1.3/docs/guide/jdbc/index.html
Hope this helps.
Good Luck.

What is the diffrence between My Runnable Interface and Java Runnable

Hi folks
all we know that interfaces in java just a decleration for methods and variables.
so my Question is why when i create an interface its name is "Runnable" and i declared a method called "run" inside it.then when i implements this interface with any class don't do the thread operation but when i implement the java.lang.Runnable the thread is going fine.
so what is the diffrence between My Runnable Interface and Java Runnable?
thnx

so what is the diffrence between My Runnable Interface
and Java Runnable?
thnxClasses and interfaces are not identified by just their "name", like Runnable. The actual "name" the compiler uses is java.lang.Runnable. So even if you duplicate the Runnable interface in your own package, it's not the same as far as the compiler is concerned, because it's in a different package.
Try importing both java.util.* and java.awt.* (which both have a class or interface named List), and then try to compile List myList = new ArrayList();
