Are Observer/Observable still alive?

Hello. I can't understand why one should use these
classes instead of the very common event listening
model, composing with, or subclassing,
EventListenerList.
I also didn't find any recent code which uses
Observer/Observable?
EnricoI prefer the names of the Observer / Observable classes but I think they aren't used because Observable is a class. Since there is no multiple inheritance in Java, it's not very useful. I have found the java.beans.PropertyChangeEvent, PropertyChangeListener, and PropertyChangeSupport classes to be a good replacement.

With 10.5.7 the MDP-to-DVI-Adapter problems are still alive!!!

I can't believe it. After more than a half year the problems with external displays (that are not Apple Cinema Displays) connected through a Mini DisplayPort-to-DVI-Adapter are still alive.
All that unacceptable screen flickering and wobbling is not fixed!
<ironic>I know we all should buy Cinema Displays...</ironic>
Be ashamed, Apple!

+1 on this issue.
Just tried it here and i still can't connect my MBP 15" U on the Dell 2408WFP via DVI on full resolution (1920x1200 60Hz).
it only works at miserable 800x600 75Hz.
What can we do? Apple should replace this faulty macs for ones that work (even if its the big 17")...

Applets are Still Alive!!!

It is weekend and we all need some rest from the work we have or haven't done. Here ( http://www.davidgilmour.com ) is a nice example that applets are still alive and great music too. Okay, for more than 30 years I'm the biggest fan of Ping Floyd and David Gilmour anyway. Enjoy!

Hello,
You may want to try issuing
java -cp weblogic.jar weblogic.Admin -url t3://localhost:7001 -username
system -password pwd DESTROY_POOL MyPool true
command before server shutdown.

Folio data build by prerelease version are still alive?

In my publication portal (DPS Dashboard), there are only 2011 July, August, September and November issue.
My 2011 February, May, April, March and June issue (build by prerelease version) are still downloadble in my branded viewer.
All of them are free.
If I want to deleate the folios build by prerelease version, how do I deleate them?
My understanding that the folios build by prerelease version are still alive is correct?

Folios built with the prerelease Content Bundler don't show up in the Folio Producer. To delete them, you need to use the Content Bundler. I believe it's still available on the old prerelease site.

Mac OS X takes very long to shut down because processes are still alive

Hello everyone!
Since the latest update to Safari 5.0.1, iTunes 9.2.1 and Trackpad Update, the system takes unusual long to shut down.
The screen gets the usual blue, a spinning wheel appears and is there for about 20-30 seconds.
Before the updates, it was about 5-10 seconds.
When booting in verbose mode, it tells me at shutdown that some core system processes (among them launchd and other boot stuff) are still alive (or, as the OS says, "PID XXXX is still alive").
The only thing to workaround (which isn't the solution for forever!) is to run "sudo shutdown -s 0" on the console.
Is there a way to avoid this waiting for still-alive processes?
Thanks in advance!

I have just restored my hard drive and now I too have this same situation. Have you been able to resolve it. If so would you be good enough to tell me how.
Cheers,

Daemon thread still alive when the environment is closed

I'm using the replication framework with the Java API in an OSGi container (equinox). I notice that when I'm closing the environment there is a deamon thread still alive. Each time I start a new replication environment and shut it down, one more daemon thread is added (and still running).
Is there a way to close the replication framework and all their associated threads?
I'm using BDB 4.7.25 - windows
thanks
dong

Hi Dong,
I don't know of a way to force the removal of the daemon thread(s).
I believe that the thread is actually gone - as long as you are closing down the environment cleanly. The alternative to using daemon threads is to ensure that DetachCurrentThread is called by the JNI layer for each thread. Given the way the Berkeley DB Java API is implemented, that is not feasible.
Are the additional threads causing issues?

Alex

Is Adobe Alchemy project still alive?

Hi, people!
Please excuse me if I missed something, but I have not heard
anything for a quite long time (since December, I think) from
Alchemy developers on this forum.
Is Alchemy project still alive? I care deeply for its fate,
and the apparent lack of reaction troubles me greatly.
There are a few outstanding questions which are causing us,
Lua Alchemy developers, notable discomfort. Most notably
the
flyield() problem and the transition to LLVM 2.4.
I understand that Adobe Alchemy is an experimental
unsupported alpha product, but even a short reply of "project not
abandoned, will be back in six months" kind would do great for our
spirits.
Alexander.

Yes, josath is right that as an Adobe employee I can't tell you much about Adobe's future plans including Alchemy. But I can say a little bit about the relationship between Alchemy and FlashPlayer and how that will probably play out in the future. Alchemy relies on special op codes for direct memory access and arbitrary jumps that need to be supported by the Flash Player. I believe FP10 was the first player version that supported those op codes. Moving forward I would say it is safe to assume that future versions of the FlashPlayer will continue to support those op codes. In other words you should expect to be able to run today's Alchemy SWFs in every future FP.
You are also asking whether Alchemy will be able to take advantage of FP performance improvements and support for, say, hardware acceleration.
My answer would be: "yes" and "no". It depends on your Alchemy SWF and on the feature that improved. For example if FP's garbage collector improved in performance and became twice as fast your Alchemy SWF would probably not benefit from that change. The reason why Alchemy SWFs run so fast is because they avoid using the GC. A faster GC will help "regular" SWFs but not Alchemy SWFs. If everything including rendering improved in performance then regular SWFs and your Alchemy SWFs would improve as well. As far as I know hardware acceleration on mobile devices is currently only accessible through the ActionScript side via cacheAsSurface. But your Alchemy SWFs are created by converting C source code to AS. In other words if you want to take advantage of hardware acceleration then you need to beef up your AS code that uses the converted C code.
Hope this helps,

Trying to publsh changes to my website. I get a message "There was an error communicating with the FTP server. Try again later, or check with your service provider." I did, and all my settings are correct, but still cannot publish

Trying to publsh changes to my website. I get a message "There was an error communicating with the FTP server. Try again later, or check with your service provider." I did, and all my settings are correct, but still cannot publish.
Any other ideas?

Most likely you are suffering from a bug in iWeb that doesn't let you publish websites if an image you have added to your site begins with space. You can either search for that image and remove it.

Hey shahbazfromgbr,
Thanks for the question, and welcome to Apple Support Communities.
I understand you are having issues with sound output on your iPhone 4S. For troubleshooting steps, the following article provides the best information:
iPhone: Can't hear through the receiver or speakers
http://support.apple.com/kb/TS1630
1. Verify that there is nothing plugged in to the headset jack, including headsets, headphones, or adapters.
2. Make sure the Ring/Silent switch is not switched to silent.
3. While on the Home screen, adjust the volume buttons. If you see the icon below, indicating that headphones are attached, there may be debris or an object lodged in the headset jack:
4. Check the headset jack. If there is an object lodged in the headset jack that is not easily removed, have the iPhone serviced to remove object.
5. For Original iPhone: If there is light debris, such as lint, in the headset jack, try connecting a pair of headphones to the headset jack and then remove the headphones. Repeat this several times to remove the debris.
6. If you have installed a protective film on the display, either ensure that the receiver is not covered or remove the film completely.
7. Check the receiver mesh (which is on the top front of the device, above the display). If it appears blocked, use a clean, small, dry, soft-bristled brush to carefully and gently brush away any debris.
8. If you have paired with a Bluetooth headset that is nearby, either use the headset or turn Bluetooth off (choose Settings > General > Bluetooth).
9. Restart the iPhone.
10. If restarting the iPhone doesn't resolve the issue, try restoring the device.
11. If the issue persists, go to the Service Answer Center - iPhone for information on service.
Thanks,
Matt M.

HT4850 I seemed to have missed the whole ordeal of keeping my 10.4.11 os x powerpc up to date. Are these suggestions still viable as I have been getting all sorts of console errors which now seem to lead me to this researched destination?

I seemed to have missed the whole ordeal of keeping my 10.4.11 os x powerpc up to date. Are these suggestions still viable as I have been getting all sorts of console errors which now seem to lead me to this researched destination? The suggestions involve putting "sudo" in Terminal Application and I am assuming that with all the console errors now being generated by my "permissions fixer" that this might be the reason...missed the class and updates as I never had problems like these before and the technology is changing. Have a whole list of console errors if someone is willing to help as I also think I have hit the motherload as to the reasons why?!

TS4000 my reminders on my 4S are invisible. they still appear on my icloud and the reminders pop up when they're due but the list itself is blank. HELP!

my reminders on my 4S are invisible. they still appear on my icloud and the reminders pop up when they're due but the list itself is blank. HELP!

Try force-closing the Reminders app and reset your phone: double-tap the home button, locate Reminders, swipe up on the image above the app icon to close it, tap the home button again. Then hold the power and home buttons at the same time until you see the Apple logo, then release and wait for it to restart. Then check your reminders again.

A distribution group with "require all senders are authenticated" checked still receives external mail

a distribution group with "require all senders are authenticated" checked still receives external mail. this does not happen for any other DG i am aware of. this also happens from multiple external senders.
please assist.
thanks

Hi,
From your description, I would like to verify if the problematic Distribution Group is a member of other distribution groups that don't check "require all senders are authenticated".
What's more, please check if there is any difference between this problematic distribution group and other normal distribution groups.
Hope this can be helpful to you.
Best regards,

My iPhoto closed unexpectedly and now it says "Rebuilding the iPhoto Library database". What is going on and are my photos still going to be there?

My iPhoto closed unexpectedly and now it says "Rebuilding the iPhoto Library database". What is going on and are my photos still going to be there?

With the amount of information you've provided it's impossible to offer a solution. We can't see your computer so we need to know the details of your problem and setup, i.e.:
what version of iPhoto are you using?
what system version are you running?
what were you doing when iPhoto closed unexpectedly?
how big is your library, i.e. how many photos?
how long has the rebuilding been going on?
do you have a recent backup of the library made just prior to this occurring?
where is your library located?
did you apply any updates or upgrades just prior to the problem occurring?
are you running a "managed" or "referenced" library?
what type of Mac?
how much free space on your boot drive?

How about janus? Is it still alive ?

Janus,the project of running linux application on solaris x86, is still alive ?

Nope! Its dead as a parrot.
However i think that Sun is looking on Xen to do similar things. Or possibly another project. But janus is dead.
RIP.

If you want to change your iCloud ID or password on your phone go to Settings>iCloud and tap Delete Account, then sign back in with your updated information. Note: this only deletes the account and any synced data from your phone, not from iCloud. Provided you are signing back into the same account and not changing accounts it will be synced back to your device when you sign back in.
