Question about debugger is issuing classesForSignature

Hello everybody.
I'm working on a project to implement a dynamically typed language on the JVM using the JSR-292 invokeDynamic infrastructure. Some other members of the team have complained about long pauses during startup when running with the Eclipse Juno debugger, and I've been able to reproduce these in both Juno and Luna.
The problem seems to be that the debugger is making a jdwp classesForSignature request for each class that has been unloaded, and each request requires the jdwp library to iterate over every single loaded class.
Since the Java 8 implementation of invokeDynamic & method handles generates a large number of small anonymous classes (which can be GCed if no longer referenced), and we are also quite careful to ensure our own temporary class files can also be GCed away this produces a lot (several thousand) classesForSignature calls, each of which has to iterate over tens of thousands of classes.
Does anybody know why the debugger is issuing classesForSignature requests for unloaded classes, and if there is some way to stop it?
Thank's a lot!

Should I get the iPod Touch? (Also a question about the screen issue)

Hi,
I recently purchased the 8GB iPod Nano, and now i'm considering to add a $100 and get the iPod Touch 8GB. Would you guys recommend it?
Another question I had was that I heard about the iPod Touch having some Screen Issues, and read somewhere that if the Box has a picture of Macy Gray then its Bad. But I personally think the Macy Gray image is for the 8GB, and the other artist is for the 16GB.
Is there a 100% definite way for me to find out if it has a good screen or not?
Thanks in Advance!
Saeid.

Ok, I recommend the iPod Touch. 8GB is fine, and totally worth the $$.
The screen issue has been fixed by a firmware update, so as long as you update to the latest firmware, you should be in the clear.
I have a 16GB macy Gray and it is working perfectly so far (1 week of ownership)
However, you mentioned using your iPod in the rain. If you do so, the Touch is not for you! I would not want to get water even near it, because the technology could be very very sensitive to water. It was raining here the other day (in Los Angeles) and I was so scared to use the touch that I took my 8GB 3gen Nano with me instead. And I was still scared to use that.
You will have to take the touch out and look at it if you are going to operate it properly.
The good news:
you can make playlists on the go! That means you can, while it is still dry, set a nice playlist without connecting to your computer. But, if the volume needs to be adjusted, there is a shortcut that would take just a bit of memorization and careful skill. In your pocket, you can double tap the home button, and then the volume, pause and track forward/backward "buttons" pop up. If you can memorize their position and hit them right, the Touch can be operated in your pocket. But make sure your hands are dry!
So it's up to you. I think quality wise, the Touch has had most of its bugs worked out. The only things that will come in the future are additional features.
Good luck and I hope you get it.

Question about sleep resume issue

Hi friends! I have the following question: When I resume my T430 Thinkpad from sleep and is not plugged in instead of bringing back the screen of my last session the computer starts booting. This cause lots of problems especially if I have any unsaved work. I didn't have this problem in the past (after I was pressing the green button my computer was always starting at the session that I left it before I chose SLEEP). I usually don't have this problem if the computer is plugged in. I also noticed that this happens only if the remaining battery time is 2 hours or less (or maybe this is just a coincidence). Has anyone else experienced the same problem? Is there a setting that I can change? Thank you!

Yes. I have this problem with my T430, but only when I have both the main battery and also the battery "slice" installed. What happens is that after the first battery is run down (the "slice" is run down first), the T430 switches to the other battery (the main battery). If I then suspend the computer, it appears that it tries to maintain the memory during sleep mode using the depleted battery which, of course, results in the same thing as removing the battery while in sleep.
I've tried to figure out how to contact Lenovo but, despite having an extended support contract, I have been unable to do so. I'm hoping someone here can help or can direct me to where I can find out how to contact Lenovo about what is obviously a flaw in their design.

A question about performance ( ram issue? )

Small question. I have a Macbook Pro unibody - it has a Corsair Solid State Drive in it. 4 gigs of ram. I have an external hard drive with a few hundred movies on it. Each movie's icon is notated with a picture of a flag where the movie's origin is. Anywho. When I click the HD to look at all my movies, it takes a bit for all of the pictures to load for the icons. Not only that when I scroll up or down some of the icon pics will disappear, then reappear. In other words - it's slow.
I previously had 8gb of ram in my 17 inch pro (i have a 15 now) - and I don't remember having this problem - but i don't really remember much. My question is - do you think this is a ram issue, an external hard drive issue - as in, it's not super fast, or some other issue. What can i do so when i open this folder up, I don't have serious lag time for the icons to show up? I think it's not a ram issue, i'm guessing it's an external issue - not so much that the external has a problem just that it's now fast, but want to check here to make sure. thanks.

How are you accessing the external harddrive? Firewire 800 is going to be faster than USB2.0 This I would expect, not RAM.
A faster connection or a faster external HD I suspect would be the answer.

Question about spinning ball issues and OS reinstall.

I have a late 2008 white MacBook running Lion. A while back I was having problems with the spinning beach ball appearing anytime I tried to change between apps or websites. I had tried the command+r on bootup, terminal, passwordreset tip to repair the permissions and ACLs. It fixed the issue for a day or two, but that is all. I ended up making the decision to back up my information and reinstall the software. Somehow after the reinstall when I went to restore my data I ended up with two separate user accounts (one was the backup). It really is a pain in the butt to have to switch back and forth between accounts when I need to look for an old file.
Anyway, I am having the same problem again. I never had an issue with my MacBook until I installed Lion. I've gone into the boot menu twice so far today to repair the permissions and ACLs and now I need to do it again. I want to try another OS reinstall, but I was wondering if anyone knew of a way to merge the two user accounts first so that I don't end up with two or three accounts after everything is said and done. I've tried to figure it out myself, but I've not had much luck.

Yeah, I've used the repair utility in the recovery menu. Sometimes when I repair the disk and run it a couple of times I find that the second time there will be even more errors than before.
That sounds like your doing repair permissions. There are certain permissions that will always show when you repair permissions, and are not an error. See this Apple note listing them.
A repair disk, which is different than repairing permissions, should not yield any error messages. If it does, you have an issue(s) that needs to be fixed. You should go back and do a repair disk. It should give you some statistics then tell you everything is OK, or give you error message(s).
Part of your spinning beach ball problem may be your 2GB of memory. Consider upgrading using either OWC or Crucial memory, both which work well in macs. A 4GB upgrade (2 x 2GB) can run $20 to $60.

A question about debugger

Hi all,
I wonder if the debugger has the following functionality: I don't set up breakpoints in a program, but when a particular class, say the class "CL_GUI_FRONTEND_SERVICES", is called, the debugger will stop the program and show where it is called?
Or is there any other way I can get the similar functionality?
Any ideas and suggestions are highly appreciated.
Best,
Bing

Question about VB OracleConnection

Hi all,
I would like to open an OracleConnection in my VB code and then call another vb function (in order to maintain good modular programming standards) within the same program using the same oracle connection whenever I try this I get a no connection open type of error.
So just to be clear, can I pass the connection between sub procedures and functions in order to not have to open and close a bunch of connections?

Sen,
Your question seems to be related to one of your previous postings in the Measurement Studio for Visual Basic Discussion Forum. Whenever you have further questions about the same issue, instead of posting a brand new question, you can simply add a "Comment" to the reply you got (by clicking on "Comment on this answer"). Here's a link to your previous posting where you can do this:
how can i control the DAQ directly from VB
Besides, you'll have a better chance of getting an answer in the Measurement Studio for Visual Basic Discussion Forum since the question is related to that product.

About the communication issues in the client-server program

About the communication issues in the client-server program
Hi, I have some questions about the communication issues in a java project, which is basically the client and server architecture. In brief, the client, written in java, can be deployed anywhere, and in the following part, assume it is in the LAN (Local Area Network) which is connnected to the internet through the firewall and/or proxy, and the server, written in
java too, simply provides the listening service on a port in a remote machine. And assume the server is connected to the internet directly so that the scenario can be simple to focus on the core questions.
My questions are as follows:
1 About the relationship between the communication port and protocol
Generally, protocols at the application level like HTTP, FTP have their own default port, e.g., HTTP is corresponding to 80,
FTP is to 25. But it is NOT necessary for the web server to provide the HTTP listening service at port 80, right? E.g, Tomcat provides the HTTP listening service at 8080. So it means the default relationship between the application protocl and their port is some routine, which is not necessary to follow, right?
2 Assume a LAN connected to the internet through a proxy, which only allows HTTP protocol, then questions are:
2.1 Does the proxy recognize the HTTP request from the client by the port number (carried in the request string)? For example, when the server provides the HTTP listening service at 80, then the request from the client will include the port number 80, then the proxy will parse such info and decide if or not the request can be out.
2.2 Does the proxy recognize the HTTP request from the client by protocol (carried in the request string)? For example, the protocol used in the communicatin should be included in the request, then the proxy can parse it to make the decision.
3 In java programm, if using the HTTP protcol, then on the client: the corresponding API is java.net.URLConnection, right?
If using the TCP protocol directly, then on the client:the corresponding API is java.net.Socket, right? In both cases, the server side use the same API, java.net.ServerSocket?
Is it correct to say that the communication by Socket is faster than URLConnection?
4 Take MSN messenger for example, which protocol does it use? Since proxy configure is only the possible option, so I guess generally the TCP protocol is used directly so that the better perfomrance can be achieved, right?
5 Given 3 computers within the same LAN, can the client, proxy, server environment above be correctly simulated? If so, can
you recommend me some typical proxy program so that I can install it to configure such an enviroment to perform some test?
6 I guess there should be some software to find out which port number a given program/process is going through to connect to
the remote machine, and which port number a given program/process is listening on? Also, what protocl is used in the given
communication.
7 Finally, regarding each of the above questions, it will be highly appreciated that if you can recommed some references,
tutorials, books etc. In summary, what I care about is how to enable the java client behind the proxy and firewall to
communicate with the remote server without problems, so if you know some good tutorials plz let me know and thx in advance!
Finally, thanks for your attention so such long questions =).

FTP is to 25. But it is NOT necessary for the web
server to provide the HTTP listening service at port
80, right? E.g, Tomcat provides the HTTP listening
service at 8080. So it means the default relationship
between the application protocl and their port is
some routine, which is not necessary to follow,
right?Not sure what you're saying here.
There must be a server listening on some port. The client must know what port that is. If you open the connection using the Socket class, you'll explicitly specify the port. If you use some higher level class like URLConnection or something in the commons Net package, there's probably a default port that will be used if you don't explicitly specify another.
There's no way for the client to know that the HTTP request will go to port 80 instead of port 8080. If you think the the client contacts the server without explicitly naming a port, and then asks the server "get me your HTTP server", and the port is determined from that, you're mistaken.
Not sure if you're thinking that, but it sounded like you might be.
2 Assume a LAN connected to the internet through
a proxy, which only allows HTTP protocol, then
questions are:
2.1 Does the proxy recognize the HTTP request
from the client by the port number (carried in the
request string)? For example, when the server
provides the HTTP listening service at 80, then the
request from the client will include the port number
80, then the proxy will parse such info and decide if
or not the request can be out. I'm not sure, but I think most proxies and firewalls are configured by ports. I thought I'd heard of more sophisticated, higher-level ones that could understand the content to some degree, but I don't know anything about those.
3 In java programm, if using the HTTP protcol,
then on the client: the corresponding API is
java.net.URLConnection, right?That's one way.
You might want to look into this:
http://jakarta.apache.org/commons/httpclient/
If using the TCP protocol directly, then on the
client:the corresponding API is java.net.Socket,
right? In both cases, the server side use the same
API, java.net.ServerSocket? A Java client will user Socket, and a Java server will use ServerSocket and Socket.
Is it correct to say that the communication by Socket
is faster than URLConnection?Probably not.

I have a question about using multiple ipads in our school. Each of our teachers have a iPad and AppleTV in their classroom. The issue is, with our classrooms so close in proximity to one another, is there a way to pair teacher #1 iPad to its AppleTV without effecting/projecting onto the adjacent teachers #2 classroom AppleTV?

Not as such.
Give the AppleTV units unique names and also enable Airplay password in settings with unique passwords for each teacher.

Questions about the IDE

Hi all,
I have some questions about the IDE's Help menu.
First, without peaking....
1. Why would you click the Help menu?
2. What would you expect to find there?
Now, you can peak
3. Is there anything in the Help menu that surprises you (gee, I never would have thought to look there for that)?
4. What is missing?

That's a reasonable dividing line. I don't know the official reason myself,
but I'm glad there are now two forums because I will not lurk on the Flash
Builder forum because I don't write any of the code for Flash Builder and
therefore have no "expertise" there.
I do write code that goes in the Flex SDK and generally know who to bug
about other code in the SDK I haven't written so if one of my colleagues is
really busy and not paying attention to forum postings I can point them to
unanswered posts in their domain of knowledge.
I would offer that the dividing line is really whether you are having
trouble with the tools, including the code generated by the tools, or
whether you are having trouble understanding with the components and
infrastructure in the SDK.
One cross-over point would probably be profiling. Even though I didn't
write the profiler for Flash Builder, I have lots of experience using it so
if you are debugging memory leak or performance issues I would ask those
questions on this forums. If you are having trouble getting the profiler or
debugger to run, though, ask that on the Flash Builder forum.

Some questions about Muse

First of all, I would like to say that I am very impressed with how well Muse works and how easy it was to create a website that satisfies me. Before I started a daily updated website I thought I would encounter many problems I will not be able to solve. I have only had a few minor issues which I would like to share with you.
The most problems I have with a horizontal layouts (http://www.leftlane.pl/sty14/dig-t-r-3-cylindrowy-silnik-nissana-o-wadze-40-kg-i-mocy-400- km.html). Marking and copying of a text is possible only on the last (top) layer of a document. The same situation is with widgets or anything connected with rollover state - it does not work. In the above example it would be perfect to use a composition/tooltip widget on the first page. Unfortunately, you cannot even move the cursor into it.
It would be helpful to have an option of rolling a mouse to an anchor (like in here http://www.play.pl/super-smartfony/lg-nexus-5.html and here http://www.thepetedesign.com/demos/onepage_scroll_demo.html). I mean any action of a mouse wheel would make a move to another anchor/screen. It would make navigation of my site very easy.
Is it possible to create a widget with a function next anchor/previous anchor? Currently, in the menu every button must be connected to a different anchor for the menu to be functional.
A question about Adobe Muse. Is it possible to create panels in different columns? It would make it easier to go through all the sophisticated program functions.
The hits from Facebook have sometimes very long links, eg.
(http://www.leftlane.pl/sty14/mclaren-p1-nowy-krol-nurburgring.html?fb_action_ids=143235557 3667782&fb_action_types=og.likes&fb_source=aggregation&fb_aggregation_id=288381481237582). If such a link is activated, the anchors in the menu do not work on any page. I mean the backlight of an active state, which helps the user to find out where on page they currently are. The problem also occurs when in the name of a html file polish fonts exist. And sometimes the dots does not work without any reason, mostly in the main page, sometimes in the cooperation page either (http://www.leftlane.pl/wspolpraca/). In the first case (on main page), I do not know why. I have checked if they did not drop into a state button by accident, moved them among the layers, numbered them from scratch and it did not help. In the cooperation page, the first anchor does not work if it is in Y axle set at 0. If I move it right direction- everything is ok.
The text frame with background fill does not change text color in overlay state (http://www.leftlane.pl/sty14/nowe-mini-krolestwo-silnikow-3-cylindrowych.html). I mean a source button at the beginning of every text. I would like a dark text and a light layer in a rollover, but the text after export and moving cursor into it does not change color for some reason.
I was not sure whether to keep everything (whole website) in one Muse file (but I may be mistaken?). I have decided to divide it into months. Everyone is in a different Muse file. If something goes wrong, I will not have any trouble with an upload of a whole site, which is going to get bigger and bigger.
The problem is that every file has two master pages. Everything works well up to the moment when I realize how many times I have to make changes in upper menu when I need to add something there. I have already 5 files, every with 2 masters. Is there any way to solve this problem? Maybe something to do with Business Catalyst, where I could connect a menu to every subpage independently, deleting it from Muse file? Doing so I would be able to edit it everywhere from one place. It would make my work much easier, but I have no idea jendak how to do it.
The comments Disqus do not load, especially at horizontal layouts (http://www.leftlane.pl/sty14/2014-infiniti-q50-eau-rouge-concept.html). I have exchanged some mails and screenshots with Disqus help. I have sent them a screenshot where the comments are not loaded, because they almost never load. They have replied that it works at their place even with attached screenshot. I have a hard time to discuss it, because it does not work with me and with my friends either. Maybe you could fix it? I would not like to end up with awful facebook comments ;). The problem is with Firefox on PC and Mac. Chrome, Safari and Opera work ok.
YouTube movie level layouts do not work well with IE11 and Safari 7 (http://www.leftlane.pl/sty14/wypadki-drogowe--004.html). The background should roll left, but in the above mentioned browsers it jumps up. Moreover the scrolling with menu dots is not fluent on Firefox, but I guess it is due to Firefox issues? The same layout but in vertical version rolls fluently in Firefox (http://www.leftlane.pl/sty14/polskie-wypadki--005.html).
Now, viewing the website on new smartphones and tablets. I know it is not a mobile/tablet layout, but I tried to make it possible to be used on mobile hardware with HD (1280) display. I mean most of all horizontal layouts (http://www.leftlane.pl/sty14/2015-hyundai-genesis.html), where If we want to roll left, we need to roll down. Is there a way to make it possible to move the finger the direction in which the layout goes?
On Android phones (Nexus 4, Android 4.4.2, Chrome 32) the fade away background effect does not work, although I have spent a lot of time over it (http://www.leftlane.pl/lut14/koniec-produkcji-elektrycznego-renault-fluence-ze!.html). It is ok on PC, but on the phone it does not look good. A whole picture moves from a lower layer instead of an edge which spoils everything.
This layout does not look good on Android (http://www.leftlane.pl/sty14/nowe-mini-krolestwo-silnikow-3-cylindrowych.html#a07). The background does not fill the whole width of a page. There are also problems with a photo gallery, where full screen pictures should fill more of a screen.
Is it possible to make an option of scroll effects/motions for a fullscreen slideshow widget thumbnails (http://www.leftlane.pl/sty14/2014-chevrolet-ss%2c-rodzinny-sedan-z-415-konnym-v8.html#a06)? It would help me with designing layouts. Currently, it can go from a bottom of a page at x1 speed or emerge (like in this layout) by changing opacity. Something more will be needed, I suppose.
Sometimes the pictures from gallery (http://www.leftlane.pl/sty14/2014-chevrolet-ss%2c-rodzinny-sedan-z-415-konnym-v8.html#a06 download very slowly. The website is hosted at Business Catalyst. I cannot state when exactly it happens, most of the time it works ok.
I really like layouts like this (http://www.leftlane.pl/sty14/2014-chevrolet-ss%2c-rodzinny-sedan-z-415-konnym-v8.html#a03). On the top is a description and a main text, and the picture is a filled object with a hold set at the bottom edge. That is why there is a nice effect of a filling a whole screen- nevertheless the resolution that is set. It works perfect on PC, but on Android the picture goes beyond the screen. You can do something about it?
In horizontal layouts (http://www.leftlane.pl/sty14/dig-t-r-3-cylindrowy-silnik-nissana-o-wadze-40-kg-i-mocy-400- km.html) holding of a filling object does not work. Everything is always held to upper edge of a screen regardless the settings. Possibility of holding the picture to the bottom edge or center would make my work much easier.
According to UE regulations we have to inform about the cookies. I do not know how to do it in Muse. I mean, when the message shows up one time and is accepted, there would be no need to show it again and again during another visit on the website. Is there any way to do it? Is there any widget for it maybe?
The YouTube widget sometimes changes size just like that. It is so when the miniature of the movie does not load, and the widget is set to stroke (in our case 4 pixels, rounded to 1 pixel). As I remember ( in case of a load error) it extends for 8 pixels wide.
Last but not least - we use the cheapest hosting plan in Business Catalyst. The monthly bandwidth is enough, although we have a lot of pictures and we worried about it at first. Yet we are running out of the disk storage very quickly. We have used more than a half of a 1 GB after a month. We do not want to change BC for a different one, because we like the way it is connected with Muse. But we do not want to buy the most expensive package - but only this one has more disk space. We do not need any other of these functions and it would devastate our budget. Do we have any other option?
I’m using Adobe Muse 7.2 on OS X 10.9.1.
and I'm sending Muse file to <[email protected]>

Unfortunatley, there is no way to get a code view in Muse. I know quite a few people requested it in the previous forum, but not really sure where that ended up. Also, you may not want to bring the html into DW unless you only have 1 or 2 small changes 2 make. Two reasons. First, it isnt backwards compatible, so if you are planning on updating that site in Muse, you will need to make those changes in DW everytime you update. Second, by all accounts the HTML that Muse puts out is not pretty or easy to work with. Unlike you, I am code averse, but there was a lenghty discussion on the previous forum on this topic. I know they were striving to make it better with every release, just not sure where it is at this point.
Dont think I am reading that second question right, but there was a ton of info on that old site. You may want to take a look there, people posted a ton of great unique solutions, so it worth a look.
Here is the link to the old forums- http://support.muse.adobe.com/muse

Questions about using a PDF form online

I have a client who wants to create an online version of a PDF form that they are currently using. I am currently trying to explain to them that this would be best done as an HTML web form, but I may not win this argument. I have only used PDFs for printed forms (either hand-written or using form fields) so I am not familiar with any problems that converting the form for use online would entail.
When the 'Submit' button is pressed on the form, is there a way to redirect to another web page after the data is submitted? (i.e. does the PDF have access to it's outer 'environment'?)
Are there any security issues submitting data using the PDF form as opposed to using a standard web form? (There may be sensitive data being submitted)
I'm not sure how they plan to handle the data that is submitted, but there are several options in the submitForm parameters - I am assuming that using the HTML option would submit the data in the same format as a web form would. Am I correct here?
Can the PDF be prevented from being downloaded or printed? This form should only be used to submit data to their server, not as a printed form.
Are there any other 'gotchas' that I need to look out for? Does anyone have a recommendation for a site which contains any tutorials or guidelines for using PDF forms online?

Thanks for the information.
Yes, I agree that there is less reason for it to be a PDF form (Actually, no real reason other than the original form already exists in PDF), but I am unfortunately in the position that my input in this project is not necessarily being considered (my company is following direct -and inconsistent- directions from the client, and I have no contact with the client to ask questions about what their actual needs are). I have been told to give the client the 'Tomato' that they are asking for, even though they are describing an 'Apple'.
The reason this form is not meant to be printed is that we have replaced the 'Signature' fields from the original form with checkboxes that the user must check to confirm they have 'signed' the document. If they are to print/fax/whatever the document, they should use the original form, not this one. And I am still trying to explain to them that this would be better served with an HTML web form, but I fear I am losing that battle.
I have brought up the fact that it is not 100% guaranteed that Acrobat will be available in the browser, although I can only guess that it is less than likely that anyone will not have some sort of PDF viewer available to their browser.
I will also mention that issues may arise if the file is not submitted from within the browser.

Questions about Indexing and Using an Indexing POA

Although I have only about 50 users, at least 15 of them have in excess of 100,000 messages in their accounts and the POA (version 7.0.2) is regularly slowing to a crawl. (I just know that plans for revolution are fomenting!) I have embarked on a campaign to reduce these accounts by archiving everything off to get mail accounts down to 3000 or fewer pieces. I have achieved user buy-in, but have worked on only a few users so far.
In another closely related thread, it was suggested to me that the PO speed issues relate to broken indexes. And I suspect that given so many messages, the indexes were never getting fully rebuilt with the default QF POA settings. I am trying to fix that situation in addition to reducing mail account sizes. So, I have set up a second POA on another server and dedicated it to the indexing task. The /qfinterval is set for 1 hour, other /qf switches at default. The POA-QF does no mail delivery, but it does do nightly user upkeep.
The POA-QF seems to be steadily working away and making progress at reducing the number of unindexed messages. However, I have questions about what I am seeing and what more I can do:
1. Is the progress I am seeing real progress? For example I have a user with over 100,000 messages to be indexed and every time I check the logs, the count drops by about 500 messages per hourly QF cycle. I assume that if I just let it keep running, it will eventually get caught up and fixed. Not only with this user, but with all the others as well. Will my patience (and theirs) be rewarded? Are there any gotchas I need to prepare for?
2. One user has recently had virtually all of her messages successfully moved to archive. I can see them in the Archive, and do not see them in the online account. However, now over a week later, QF still shows >130,000 items still left to index for that user. The POA-QF is making slow, steady progress reducing that number, but why is this user's QF count still so high? Does it just need more time, or is there something amiss for this user?
3. I may want to rebuild indexes for single users from scratch. I have seen the TID 3105742 which tells how to do this: Essentially you turn off mail delivery functions, and make some other switch changes to dedicate the POA to indexing for just a single user, and then you let the POA rebuild the indexes. The implication of that scenario is that the POA is now enjoying exclusive access to the user's databases.
If I want to use my secondary POA-QF to rebuild a user's index from scratch, does the main POA have to be offline and the user out of GWise? That is, Does the QF process require exclusive access in order to rebuild indexes from scratch?
Thanks for any thoughts or suggestions.

Set this switch for this indexing POA - /qflevel=999 - this will index
everything in one run. It will take a long time, but with no qflevel switch you
are indeed only indexing 500 messages at a time, and if the user has that much
mail, it might never really catch up.

This is odd, because really the index count should drop to nothing, but with the
above switch this might get resolved as well.

Not really - the POA is not enjoying exclusive access to the user's database,
the indexer is just avoiding an attempt to index anything else.

No - QF never requires exclusive access. That said, you may find that an
extremely vigorous QF can cause slowdowns for the user.

Legality questions about Home Sharing

I have some legality questions about Apple's Home Sharing technology.
As I understand it, you can share (that is, copy it from one computer to another) your music, movies, applications and other iTunes-managed files amongst five computers. The only 'trick' is that each computer must have an iTunes Store account and must be logged in in order for it to work.
My question concerns the copying aspect and the legality of it. For content that was purchased through the iTunes Store I can see how Home Sharing can provide a limitation on content sharing, since all of the machines would need to be connected to Apple's servers in order for the validation process to happen. But what about content that was added to iTunes through other means, e.g., ripping my own CDs or converting my DVDs? These items can still be copied via Home Sharing and as there's no DRM on them there's no way they can be protected against "illegal" or "unauthorized" use.
It was my understanding that if I gave a copy of a song to someone else, that's illegal. Apple's Home Sharing technology seems to facilitate this action. If I rip a CD or DVD into iTunes and someone copies it out, isn't that making an illegal copy? Can I be held liable for distribution of content?
And how far does this extend? If I live in a house with four unrelated people, are they legally (?) allowed to copy music and media amongst each another? Is there a perceived or actual difference between using Home Sharing to copy a movie versus, say, using a USB flash drive? And what if one of them moves out? Am I legally obligated to go through that person's hard drive and remove content that they copied from me before they leave the building?
Does Home Sharing somehow retroactively change the copyright application on a given CD or DVD? Most of my CDs and DVDs contain notices and warnings against distributing copies. Can these warnings now be ignored, or at least amended with "...unless you're using iTunes Home Sharing" at the ends of them?
I am not trying to stir up a hornet's nest here. I'm only trying to better understand the legal issues surrounding Home Sharing and particularly how they relate to unprotected content. It seems very contradictory that the RIAA and MPAA would be fighting so hard against peer-to-peer services like BitTorrent and Gnutella while apparently allowing peer-to-peer services through iTunes Home Sharing.
Furthermore, I also understand that the intention of this system was to allow families who are living together to have common access to all of the "household" music, but my issues aren't about this. I envision, for example, a college dorm building where there's several hundred people living together on the same network subnet, and all of them have Home Sharing enabled and everyone is copying thousands and thousands of songs to/from one another. Is this now legal?
Any insights would be appreciated. Thanks.

If I rip a CD or DVD into iTunes and someone copies it out, isn't that making an illegal copy?
RIPping of commercial, encrypted DVDs (most of them) is illegal to begin with. Or rather, breaking the encryption on a DVD is illegal and in order to RIP the DVD, you must break the encryption. SO you have already "broken the law" by having a copy on your computer.
Most of my CDs and DVDs contain notices and warnings against distributing copies.
Most of your DVDs have a notice about even simply making a copy, not only distributing copies.
Much of your post has been cussed and discussed by many, many people (lawyers, corporations, organizations, individuals, etc.) and no one has come (or likely ever will come) to a complete agreement.
Generally, "sharing" in the same house hold amongst family members seems to be okay. Outside the same household/family is almost always not okay.

No.
This is exactly what Napster was and why they were sued & shut down.
I imagine Apple lawyers have done their homework as well as consulted with the labels to discuss these exact issues.
And it's called "Home Sharing" to indicate that it is not "Dorm Sharing" or "Workplace Sharing", or even simply "Library Sharing"etc. even though it may be possible to use it in other places than the Home.
Users on other computers need to know your iTunes ID and password to enable it Home Sharing. Likely this is how Apple got the lables to be okay with it.
Are you gonna give (and get) dozens/hundreds/thousands/any other users your iTunesID & password?
