Is object pooling still necessary?

I’ve have implemented a transport server in Java, which creates many objects of the same type. In consideration of the compiler improvements does it make sense to use object pools like http://jakarta.apache.org/commons/pool/ nowadays?
What do you thing?
Thx,
Chris

Or only very rarely. Only if you have an object that is particularly
costly to create, e.g. a state machine for a parsing or
cryptographic engineIt is quite interesting though. I built a parser recently, and pooled the state-machines. However, I did all allocation for buffers (byte[]) on demand.
Performance wasn't great - so I created an allocator interface - and put my HeapAllocator head-to-head with a PooledAllocator.
Bang: 35% performance improvement with pooling.

Is an audio interface still necessary?

I am using
Logic Pro X, Samson L2400 24 channel mixer connected via USB, is an audio interface still necessary to record all 24 tracks separately?
Noob hardly expresses my incompetence here so thank you for your patience.

Articles I read state USB can theoretically carry 255 channels but everything else points to L/R Stereo.
It appears a fire sale is in order and purchase of a firewire mixer or interface may be my only option
Thanks everyone hope I can find a solution
I don't quite get your conclusion: the fact that an interface connects via USB, does not make it useless. And according to a quick look at specs the octacapture aka UA1010 has 10 inputs; you could aggregate that with the Samson and another interface with at least 12 inputs, and there you have your 24 inputs: 10 from the UA1010, 2 from the Samson itself, and 12 from whatever extra interface you'd use.
Getting one interface with 24 or more inputs may be a more secure and simpler route to take though.
I also don't get why you almost blame our appreciated assistance - by "howevering" it - for confusing you about your 10-input audio interface, when you never even mentioned you had it in the first place?

Heatsink replace still necessary or not?

after getting rid of the rss with the help of firmware - is it still necessary to replace the heatsink?

Halli,
Thanks for the link.
The article came out on September 6th, so the firmware update it refers to is the previous one.
The writer's understanding of the issue seems to be a little patchy. For Example:
• He refers to the "CPU thermometer itself". In fact there are four heat sensors built into the CPU, but none of them are involved here. The problem is with one of the two thermistors which are part of the heat sink assembly.
• Any short circuit is likely to be caused by the insulation on the thermistor's leads being damaged by heat rather than by expansion of the heat sink.
• There was no relocation of the sensor and cable on the new heat sink, just added protection.
I can't see any reason at all for a recall now; most people are not affected by the issue and most of those that are can easily fix it in one minute with the firmware update.

Object pool for DTO objects

Hi,
I am using BlazeDS to (de)serialize many identical small objects between a Flex client and a Java Servlet. For efficiency, I would like to create object pools on both sides. Is this possible with BlazeDS?
Thank you,
Andrej van der Zee

Hi,
Thanks for your reply.
Are there any thoughts how I can do this on the client? As far as I can see, deserialization of DTOs is hidden in the remote object. How can I tell a remote object to use a factory method for creating certain DTOs?
Cheers,
Andrej

Object pool for DTO objects
Hi Andrej,
The answer is no. There aren't any object pooling features in BlazeDS for pooling DTOs, either on the client or the server. If there are any third party object pooling solutions for DTOs on the server though you could maybe hook one of them in. . . either in your Java servlet or a RemoteObject. . . but I think anything on the client you would have to write yourself.

Java object pooling

Hi all,
Is there an Object pooling mechanism available in J2SE?
Does anyone know of any good open source object pooling implementation?
Thanks in advance

Unfortunately, the Jakarta's object pool is very ineffective for objects requiring a long construction time.
The pool can grow dynamically (when no idle object available for allocation and pool is not exhausted yet) and new objects might be constructed inside borrow method. Since the borrow as well as the freeObject are both synchronized (on the pool instance' lock), all other waiting clients will have to wait for that lock to be released before they can either release used object or borrow one.
Bottom line, you better not use this pooling API for pooling objects such as connections which have a very long construction time.
I built a very efficient object pool and will be glad to share it with others.
Just tell me where can i post it

Poolman Object Pooling

Hello all,
I am having problems with CodeStudio's PoolMan. I need to create a pool of custom objects, but it keeps on saying that my object can not be found. I can use the exact same code and use java.lang.String as the pool type and it works great... any ideas would be great!
Here is the log file from my poolman startup...

Never assume always check A lesson I had drummed into me as a youngster. In this case your assumption is wrong, this exeption is always thrown if the class stated is not in the classpath. This particular classpath is Tomcats, not your client app. Drop the jar with the class in $TOMCAT_HOME$/webapps/[your root]/WEB-INF/lib.

HT1386 Is it still necessary to sync to your desktop iTunes?

I would like to load Windows 8 Release Preview to my Dell PC. I also have an iPad and iPhone - which I'm assuming will not be able to be synced any more, when I do that. Is it still necessary to do a sync to iTunes, or can these devices now stand on their own, with the advent of iCloud, iTunes Match, and so on?

Thank you, my friends. I'm going to save my dough and buy an iMac, which is what I really want anyway. There is just far too much uncertainty at this point surrounding Windows 8, not only with regard to iTunes but other key pieces of software as well. The disclaimers and warnings Microsoft is publishing about the release preview make my hair stand on end.
I'm not a techno geek and have no interest in being. I do like for things to work the way they're designed, with no surprises. Which is why the iPad and iPhone seem close to miraculous.
Thanks again, folks.

RMI Server Object Pooling

Hello All,
Does WLServer6.1 take care of having a pool of RMI Server objects, similar
to the way EJB container does it for EJBs. I guess what I am trying to
achieve is an effect of Servlets that spawn light threads per invocation
though now using RMI Server Object. I did look at the "executeThreadPool"
options which would allow for increasing performance. I am not 100%
satisfied with it though. Is there any way I can do this. Thanks,
Chirag

Are screensavers still necessary?

Is a screensaver still needed? I have a Mid 2013 13" MacBook Air. I'm curious if I need to be concerned with using a screensaver. I use one when I'm in public or around others, just to ensure privacy and all. But when I'm alone, can I just turn off my screensaver? Is there a possibility of image retention or screen burn in from not using a screensaver on modern displays?
Thanks for any direction you can provide.

Hey OGELTHORPE,
If memory serves me right, screensavers were originally created to ensure that older CRT monitors would not experience burn in or image retention when left on a particular screen for too long. Considering that, it begs the question, are they still needed for computers with modern monitors?
I have noticed a few retina MBP owners raise the issue if image retention on their displays so perhaps for them it is an issue.
Or will I damage my MBA screen if I do not use a screensaver?
Though not 'proof positive' I have not seen any such complaint for 'ordinary' led MBPs or MBAs nor have I witnessed any such issue with my equipment. One could argue that it may not be necessary, but then a nice screen saver does have some entertainment value. I can leave it for each individual to decide if they want it or not.
Ciao.

Object key is necessary to imp. OSS note using note assistant

Hi,
Anybody can tell me is it necessary to obtain object key from SAP before implementing oss note, using Note assistant.Im not clear with object key, let me know about object key.
bi,
vijaya kumar

As far as I know, no object key is required to implement OSS Note, using NOTE Assistant.
For more information on Note Assistant, go to http://service.sap.com/notes
There are a couple of tutorials available along with user manual.
You will find that useful.

Fundamental questions on Object pooling

Hi,
I ve a class which exposes only utility methods and objects of it wont have any state at any point of time. Now which pattern should I use here...1. Can I go for Singleton pattern so that all calling classes will work on same instance in one JVM? 2. Each calling class will create one instance use it and nullify it? 3. Expose all utility methods as static methods so no physical instance in JVM as no state is needed.?
Would having only one instance degrade the performance or boost in case of having a new instance everytime?
Please share ur views on this. Pros and Cons on each pattern.
Thanks in advance

Hey Chris,
For transporting objects either in IR / ID prerequisite is that you must have already configured your XI Track properly using landscape configurator as it defines the transport route for the corresponding XI objects based on the s/w component version.
As for ID doesn't have any s/w component version we define SAPINTDIR 3.0 as s/w comp. It refers to all the objects in the ID.

FOR Integration Directory transport Test(Consolidation)->Prod:
When the objects are transported from test to productive landsape unless any changes have been made to the objects in the test landscape all the objects can be transported to the id with out any complexity. CMS takes cares of conversion of the business system to that of prod if required. Usual convention that is followed is to maintain same naming schema for the objects.
cheers.

Does Business Objects XI still support RDC for Crystal Reports?

Post Author: DLO34
CA Forum: Integrated Solutions
My company develops an application which uses Crystal Reports to present data to the user. We have been using the RDC API through our internal C code for a while now. From the documentation I have found on this site I cannot be certain that BO XI will support RDC. I have found documents discussing the new RAS API and how to migrate applications to RAS. Will BO XI still support RDC or will we be required to write to the new RAS API? Any help would be greatly appreciated.

Post Author: ejthunder
CA Forum: Integrated Solutions
Hello,
The RDC is a development tool, so your post is better suited under the Development | Other category in the forums.
The RDC is still supported in CR XI (v11.0) and CR XI R2 (v11.5). The RDC has been depricated, so it's no longer receiving development focus, but it will still be supported for the lifecycle of the products it ships with. No firm retirement date has been given to anyone yet, but it's likely that the RDC will be retired in the next release or two.
The RAS API is a very powerful report design API, however it's not a true replacement for the RDC (unless you're using Report Creation API calls with the RDC now). RAS can be used with the .NET, COM (ASP), and Java SDKs.
Depending on how you actually use the RDC you'll want to consider which SDK you're going to migrate to - .NET, or Java, and then consider which API is appropriate.
I hope this helps.

Is the XSKey in Logic 9 still necessary

Do I still need my XSKey with Logic 9 (I had it from Logic 7)?
I took it out and Logic still seems to work.

If Logic Pro 9 is a full new application or an upgrade, it is in itself a full application and requires no earlier version of Logic or an Xskey. Contrary to the install instructions which are wrong.
I have a new Mac Pro and installed an upgrade from LP7 to LP 9 and it required no Xskey or LP 7 or 8.
It works perfectly and imports projects from LP 7.
And just for good reason I installed OS 10.5.8 (Leopard) and I don't have any of the issues that appear on the forum with people running 10.6 SL
All the best and long live Logic Pro, 7 or 9

Still necessary to manually install kernel modules with CUPS?

I'm just setting up my system with CUPS for printing. In the "Configuring CUPS" section of the wiki, you're instructed to install the appropriate kernel module with modprobe for using a usb or parallel port printer. With my usb printer and kernel 2.26.9 I found this is unnecessary. Plugging in the printer caused the module to automatically load. Is this because I'm using input hotplugging? And in any case, should the wiki be edited to reflect situations where loading the module manually is no longer necessary?

Sure, feel free to edit the page to reflect what you're seeing, which is udev autoloading the appropriate module when it detects the device. This functionality has been in place for a long time, and is not related to input hotplugging as used in xorg (not sure if that's what you're referring to above).
