A few questions and some things we found about Memory Management

We have been development a pretty complex RIA in flash; true
we probably should have used flex but we are very heavily invested
in flash and moving to flex was not really an option due to time
constraints and the learning curve associated with changing. That
reminds me are the Flex UI Objects going to be made available for
Flash CS3 I mean that advanced datagrid would be nice?
The application is a order processing and document
management system that has around 150 swf’s and I am posting
here to let people know what we found through our development and
testing cycles and also have a few questions that I am hoping
someone will at least point me in the right direction.
We were kind of disappointed to find that you could no
longer duplicate Movies and were forced to reload them if we wanted
different instances, but we got over that fast. Keeping this in
mind we decided to make as many dynamic screens as we could but
these turned out to be horribly time consuming. I mean sure we
could make the fields jump around like fleas on a dogs back (and it
was a great joke) but not very practical. So back to the IDE and
fla creation we went. This leads me to my first question has anyone
see heard of or thought about a SWF file reader that would read the
layout of a SWF and then generate the actionscript as output?
As we were developing we found that it was more complex, and
I think unnecessarily so, to get connected to a database. We use
ColdFusion as our “middleware” so it wasn’t to
bad and this leads me to my next question. Is there or has there
been any indication that Flex data services or well I guess BlazeDS
now is available for Flash CS3?
So we went on our merry little way and everything was going
great until testing this is when we started to see what kind of
memory flash really eats up. In the beginning our app would take up
a gig through the course of a day.
Any Class that we created we added a CleanUp method to it.
Yes we used weak listeners, yes we destroyed, and all references to
the main movies, and yes that was it the main movies.
Don’t be fooled the same way we were. The Garbage
collection simulation
http://www.adobe.com/devnet/flashplayer/articles/garbage_collection.html
does not really tell you the whole story. Even though if you cut
the line from the root the simulation suggests that the rest of the
objects that you have created within that object will be marked and
collected. Not so.
After much testing we found that if we wanted a full recovery
of memory the object and it’s sub objects and sub sub ojects
within arrays also with sub objects must be deallocated and then
assinged null to get full collection, I say full but really mean
between 90-95% reminds me of my C programming days.

  • How do I get out of kernel panic?  kernel panic upon boot.  I did that hard drive cleanup and reinstalled Lion.  What about memory?  Anyone think I need to upgrade my memory?  I have 8gig.

    I get kernel paic upon boot.  I did that hard drive cleanup and reinstalled Lion.  What about memory?  Anyone think I need to upgrade my memory?  I have 8 G of upgraded RAM. (20 inch iMac core 2 duo)

    If you're able to boot, launch the Console application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Console in the page that opens.
    Select the most recent panic log under System Diagnostic Reports. Post the contents — the text, please, not a screenshot. For privacy’s sake, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header and body of the report, if it’s present (it may not be.) Please don't post "shutdownStall" or "hang" reports.
    If you can't boot in the usual way, try a safe boot. The instructions provided by Apple are as follows:
    Be sure your Mac is shut down.
    Press the power button.
    Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
    Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
    During startup, you’ll see a progress bar, and then the login screen, which appears even if you normally log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    Safe mode is slower than normal, and some things won’t work at all.
    Note: If FileVault is enabled under Mac OS X 10.7 or later, you can’t boot in safe mode.

  • Hello I have a few questions and I need some help with my iTunes and  iPod

    Hello iTunes people.
    I have a little problem with my iTunes. I actually almost know nothing about iTunes really. But I have had a 80 gig ipod .. ummm I think it's a iPod classic maybe. A long time ago I just downloaded iTunes. I think one of my tech friends already had put the program onto my PC so I did not even have to download it. Anyways I put my life's collection of mp3's onto iTunes and then syncs it with my iPod and it worked great. Here is my problem. I just recently bought a MONSTER PC. I have lovingly named it " ED209 " I downloaded iTunes for it and I have the most up to date version.8.1.1 is the most current version correct? Ok well here is my problem. What I want to do is I want to put everything that is currently on my iPod ONTO the iTunes library. I DO NOT want to import anything from the library or playlist or whatever you call it ONTO the iPod because there is nothing in the library. Now this is were its gets weird and possibly silly. A person I was chatting with on Facebook sort of made fun of me because she was like " Dude! Just push " Sync " But the reason I am paranoid is because THIS is the message I get....
    " The iPod " Aaron's iPod " is synced with another iTunes library. Do you want to erase this ipod and sync with this iTunes library? "
    HOLY COW!! That girl on Facebook was making fun of me but READ THAT. That exactly says ERASE the "iPod" and Sync with THIS library " It does not say put what is ON the iPod into THIS Library. It says it the other way around. Clear as day it says it will ERASE the " Ipod " it does not say " Fill the library with whats on your iPod "
    Do I all of a sudden not understand English or something???? I know how to freaking read and from what it says is sounds a 100 percent like " we will ERASE youe iPod and put everything from this playist or library onto your iPiod" But there is NOTHING in my library? Am I mentally challenged or what?
    I hope someone can help me here and I have another request. Could someone just tell me all the cool things I can do with iTunes and my iPod? I am trying to read the help files and the FAQ and whatever else Apple provides you with but it has SO MUCH crap that looks usless. I find myself reading a whole paragraph about some simple little section of s section of a section of a feature! Know what I mean. Someone give me the long and short of the neat things I can do with this stuff. I have windows Vista with a wicked computer that has like 6 gigs of ram and m iPod is a 80 GB Classic
    help !!
    PROTEUS

    *What I want to do is I want to put everything that is currently on my iPod ONTO the iTunes library.*
    1). Connect your iPod to your computer. When you get the message that it is linked to a different library and asking if you want to link to this one and replace all your songs etc, press "Cancel". Pressing "Erase and Sync" will irretrievably remove all the songs from your iPod.
    2). When your iPod appears in the iTunes source list change the update setting to manual, that will let you continue to use your iPod without the risk of accidentally erasing it. Check the "manually manage music and videos" box in Summary then press the Apply button. Also when using most of the utilities listed below your iPod needs to be enabled for disc use, changing to manual update will do this by default: Managing content manually on iPod and iPhone
    3). Once you are connected and your iPod is safely in manual mode there are a few things you can do to restore your iTunes from the iPod. iTunes will only let you copy your purchases directly from an iPod to the computer, you'll find details in this article: Copying iTunes Store purchases from your iPod or iPhone to a computer
    For everything else (music from CDs, other downloads and including iTunes purchases) there are a number of third party utilities that you can use to retrieve the music files and playlists from your iPod. You'll find that they have varying degrees of functionality and some will transfer movies, videos, photos, podcasts and games as well. You can read reviews and comparisons of some of them here:
    Wired News - Rescue Your Stranded Tunes
    Comparison of iPod managers
    A selection of iPod to iTunes utilities:
    TuneJack Windows Only (iPhone and iPod Touch compatible)
    SharePod Windows Only (iPhone and iPod Touch compatible)
    iPod2PC Windows Only
    iDump Windows Only
    YamiPod Mac and Windows
    iPod Music Liberator Mac & Windows
    Floola Mac & Windows
    iPodRip Mac & Windows (iPhone and iPod Touch compatible)
    iPod Music Liberator Mac & Windows (iPhone and iPod Touch compatible)
    Music Rescue Mac & Windows (iPhone and iPod Touch compatible)
    iGadget Mac & Windows (iPhone and iPod Touch compatible)
    iRepo Mac & Windows (iPhone and iPod Touch compatible)
    iPod Access Mac & Windows (iPhone and iPod Touch compatible)
    TouchCopy Mac & Windows (iPhone and iPod Touch compatible)
    There's also a manual method of copying songs from your iPod to a Mac or PC. The procedure is a bit involved and won't recover playlists but if you're interested it's available on page 2 at this link: Copying Content from your iPod to your Computer - The Definitive Guide
    4). Whichever of these retrieval methods you choose, keep your iPod in manual mode until you have reloaded your iTunes and you are happy with your playlists etc then it will be safe to return it auto-sync.
    5). I would also advise that you get yourself an external hard drive and back your stuff up, relying on an iPod as your sole backup is not a good idea and external drives are comparatively inexpensive these days, you can get loads of storage for a reasonable outlay: Back up your iTunes library by copying to an external hard drive

  • Got my apple TV TODAY! few questions and my thoughts

    After watching the keynote and seeing the new itunes rental system i decided to go out and buy the appletv... I wanted to jump the gun and get it before the update comes out... Anyways, few questions
    1) I don't think this is possible but is there anyway to stream a DVD playing in my computer to apple TV? I understand Apple TV uses quicktime, and quicktime can't play DVD's so I am thinking it is not possible.. Am i correct? I really hope I am wrong on this one though ahaha.. I know i can rip then convert but that takes way too much time...
    2) I have read conflicting answers to my next question, the apple support article states that you can already stream rentals from itunes to the appletv but that is not possible yet.. Am i correct? just want to make sure my appletv isn't messed up... According to the apple website the unit needs the upgrade so I assume I am right here too...
    3) last, anything else i need to know or that you might think i would find useful when it comes to appletv??
    I love apple and have been a long time apple user... Appletv didn't float my boat at first and was a pretty lame and expensive device i though... HOWEVER, take 2 seems to be a very nice step in the right direction.. FIRST, no monthly subscription fees like netflix and tivo while still being able to rent and pay as you go without using a computer (This netflix feature is coming late 2008 when their box releases).. I think i am going to love the new integration with web gallery!
    There are still some features i would like to see in apple TV and i will be submitting feedback about them ocne the update releases, but this step and price drop warrants a purchase imo..

    I had the same idea... I felt that 40 GB would be plenty especially b/c i plan to use it mostly for rentals... But it also gives me "Insurance" incase the appletv becomes huge after the update and apple decides to release a new generation in the next year or so or if i decide i actually do need more memory.. I won't feel as bad buying it knowing i only spent $229 on this one.. but i would be pretty upset with myself if i purchased the big model and never used the memory or if apple released a new generation in the next year....
    BTW, if you purchase it at a reseller, make sure you take an apple add with you.. they may not have rolled the price back.. Circuit City was like that, i had to show the apple home page to get it for 229

  • "Sleep of death" question and some observations

    I just recently upgraded to an S3 from a Fascinate, and I've been impressed so far.  The only thing I really didn't like about my Fascinate was that it would suddenly freeze or crash one every week or two, and the only thing I could do was open the case, remove the battery, and then put the battery back in.  Then I could reboot the phone and all was well.  Well, after not using my S3 for an hour or so, I tried to wake it up and nothing happened.  I couldn't turn it off (or on) either.  Sleep of death.  I had to open the case, remove and re-insert the battery to use the phone again.  Is this a common problem?  What could be causing it?  Is there any other way to fix it? 
    Overall, I really like the S3.  It's a significant upgrade from the Fascinate.  Screen quality and size (larger but not too big), processor speed, and 4G LTE are great.  I have a seven year old iPod that is still hanging in there, but I hope to use my S3 in my car (2012 Prius II, no Nav or Entunes) to listen to my music if and when my iPod dies.  I can't get music to play on my car stereo when I plug my S3 into my car's USB port (I'm told its because the S3 doesn't support mass storage mode).  But, after uploading some iTunes music to Google Play, I can play it with my S3 over Bluetooth audio.  The sound quality is good, but not quite as good as a USB connection is.  I'm experimenting with various audio settings in Google Play Music to see if I can enhance the sound quality.  If anyone knows how to play audio with an S3 over a USB connection, I'd be interested in finding out. 
    I haven't used the camera very much yet (I have had the S3 only two days) but the few photos I have taken look good.  Battery life seems to be improved over the Fascinate.  Call quality also seems up a notch.  I haven't yet tried some other features, and still others i have yet to discover!  This phone comes with very good reviews, and I can see why. 
    I can also say that I was very pleased with the service I was given at the VZW store in Augusta, Maine, when I went to upgrade my phone.  So far, other than the sleep of death issue, I'm a happy camper.

    Stop using the stock browser and use Chrome instead.  See if the "sleep of death" goes away.

  • A few Questions and opinions

    Ok, I'm looking at getting a mac mini, as a replacement fora jaded old Tiny PC. Im basically wondering whether the mac mini is substantial for my needsa nd whether anyone ahs any problems or opinons on them. Basically i need a small home computer which will be used simply for the internet, microsoft office, and perhaps something like football manager 2007. Will the mac mini be able cope with this?
    thanks

    This question comes up quite regularly, and in response I think the most important thing to say is that one has to be careful not to mistake the size of the Mac mini as any indication of it's performance. Inside that small package is a fully-fledged desktop computer which in most respects comes close to equalling the performance and power of the top of the range Mac from just 2 or 3 years ago.
    It suffers two limitations in my view. The first is not so much the system itself as it is the current state of software, because like every other Intel-based Mac, the fact is that at present, a number of the most common applications are still not written to run natively on Intel processors. As a result they run, but require the use of an on-the-fly translator to convert them from PPC to Intel code. Rosetta, the translator, is provided as part of the OS but requires a lot of memory and as would be expected, doesn't generally run particularly quickly. To use software such as the current version of MS Office, Adobe Photoshop etc, it would be wise to add as much RAM to the system as possible (the max is 2Gb) to allow 'room' for Rosetta to work. Intel versions of these packages, including MS Office, are due next year.
    The second is a relatively slow hard drive. The drive is, in fact, the same as those used in the laptop models, and runs at 5400rpm. It doesn't really impact greatly on system performance except at times when there is significant drive activity. The system can be improved once again by increasing RAM since this helps reduce the background 'paging' activity (reading and writing to virtual memory) but when dealing with large data files, system performance will always be limited to some degree by the performance of the drive.
    Fortunately the first issue can be resolved by sticking entirely to Intel-native applications, which means that if you need an MS Office compatible package, you can actually avoid the current (non native) Office by downloading Neo Office, which is Open Source and Intel Native. It's not as elegant as the Intel native Microsoft product promises to be when it is released, but it works and at the very least should tide you over until MS release their software.
    Otherwise, a Mac mini is capable of a lot more than basic tasks. I have a number of them in use in networks I manage and their users are very happy with them, including one user who uses his for complex video editing and production.
    These are remarkable little systems that seem to rarely disappoint.

  • A few questions and comments about the 2010 MBP i7

    Hi! I'm pretty new to owning a Mac computer and I actually always wanted one. I bought the top of the line Macbook Pro 15" i7 8GB, 500GB SSD notebook. I have a couple of questions on its usage.
    1) Overheating is a big issue. Many people noticed overheating with the i7 MBP. Temperatures range from 38C to 60C when using iTunes/Safari/Word. Temperatures shoot to the 70C-85C when playing games. Once you hit the 70C mark, the notebook part above the keyboard is pretty hot. However, I wouldn't care if it doesn't damage my computer so my question is, will 85C temperatures damage a Macbook Pro?
    2) Screen Scratching: Do MBP screens scratch easily? I have quite a few fingerprints a day on the screen but is it like the iPod Touch anti-scratch screen?
    3) Freezing: I've been having the MBP for 2 weeks now and my MBP has frozen twice. It wasn't because of the heat but Finder wasn't responding and I could not force quit. However, it worked after 30 seconds. Does this happen often and will it be a long-term issue?
    Even after the overheating issue, Macs are still better than PCs. It's so much easier and neat than a PC.
    5) Do you guys have any tips to using a Mac? Any accessories?
    6) I installed SMC Fan Control. If I set it to 6000 rpm, will there be any significant damage to the fans? Are the fans durable?
    Thank you all for the help!
    Message was edited by: kevinzhengli

    Just came across this thread while looking for info on the newest MBPs, and their (lack of) ability to cool themselves. Wanted to throw my 2c in.
    I have to strongly disagree with the recommendation to not install fan control software. I have an early 2008 MBP, and I frequently play video games and encode video. When left to defend itself, I have witnessed the CPU temp reach 202 F. Sorry, but that's totally unacceptable, and I manually adjust the fans to mitigate the heat.
    After 2 years of this, I am convinced the excess heat has harmed my system. It's very disappointing to hear that the new models still have problems with heat.

  • Newbie to keynote; some questions and some observations about this group

    Hello, my attn was called to this group. I have seen some impressive presentations in keynote so maybe it is time to switch.
    From what?
    I do a lot of presentations. I use acrobat. Prepare my page in whatever app is best for the job; print to pdf; include fonts. By using the app of my choice I get just what I want in my slide.
    I can readily arrange slides in sorter in acrobat. Allows minimal animation, by, say, preparing the full slide, make copies, and delete progressively. sort to show from the least to the fullest; works for me.
    pdf allows touch up text and adding text, which I often think of at the last minute. Drawing an oval or line to point to something. For heavier editing open a slide in illustrator and save as pdf.
    So, as I say it works for me. Not glitzy. Certainly pretty easy to produce decent slides.
    Most everyone has acrobat on his/her machine, so if I take my presentation on a stick, it can work, nicely, cross platform. Very few occasions when that didnt work.
    So I would like to hear folks' experiences. Can you take your presentation on a stick and show it on someone else's computer?
    What about posting presentations. I generally put my pdf on my web page, giving the audience the url; seeems to work fine. Again I ask for experience.
    Seems like quite a learning curve for keynote. And I browsed about 4 pages of discussion on this board before posting. I saw mostly complaints and problems, and not all that many solutions. And very few raves.
    So, I would welcome some testimonials.
    PS I dont want to do anything so glitzy that folks will come up to me after the talk and say nice animations; better they talk to me about the substance of my talk.
    thanks in advance
    -trog

    Welcome to the forums, troglodyte.
    If you want a testimonial, I think that Keynote is hands-down the easiest to use presentation tool, and produces by far the best-looking results. It is far ahead of PowerPoint.
    Keynote produced beautiful results, even when converted to PDF, as it has very nice graphics features (e.g., drop shadows, masking, transparency). If you are most comfortable with PDF, and don't need animations or transitions, then Keynote still has a lot to offer. That said, much of the "wow-factor" of Keynote comes from its lovely and sophisticated transitions and animations.
    (These features needn't be just eye-candy, either, as they can serve to emphasize points and help unify certain material. For example, I use transitions that are more obvious, such as the "Doorway", to mark major changes of topic in my presentations, and more subtle ones, like "Dissolve", to change between related slides. This "grammar" of transitions helps to make the presentation more comprehensible.)
    Keynote is not cross-platform, so you can't put a native Keynote presentation on a memory stick and be assured that it will work on someone else's computer. However, PDFs make from Keynote should function just fine. Alternatively, you can use various of the other exporting options in Kenote, including Quicktime, Flash, and PowerPoint, to provide more cross-platform compatibility than Keynote does (each of these conversions has its own limitations however). And several of these formats are also appropriate for web deployment.
    I find Keynote extremely easy to use. Do realize that these forums are primarily intended for troubleshooting, so you won't find a lot of generic compliments to the application.

  • My ipad got wiped and I have lost a few books and some magazines I had a prescription with :-( . Any ideas.

  • My new Ipod and some things I noticed, including scratching

    I got my new 60gb black Ipod, very happy with it, no issues with videos converting etc works exactly as expected and should.
    However I have noticed that I already have a good few scratches on my new Ipod, I was very careful with it as I knew there could be issues etc....So I never touched the screen, never let anyone else touch it, never place it face down etc and never put it into a pocket etc....
    However, what I have noticed is that there are marks/scratches on it even though I was very careful, the screen has a few and there are a few arund the click wheel. The only thing I put it in is the sleeve/pouch that comes with the Ipod and I am positive this has actually caused the scratches....
    Has anyone else noticed this...? Not much I can do now, so does anyone know of a good case for it before more of this happens....what about repairing the scratches, any ideas...I am in Europe so the shield is too expensive to import...
    Thanks..

    Yes, well I took my plastic bit off as it was all in
    one and the click wheel would not work properly with
    it left on....shame they don't have a case for it...
    I cut it half just below the lcd screen, when I received my iPod.
    And I'm going to put one of my universal PDA film (it was pack of 5) as the original half-cut one starts to get bubbles underneath.
    Why don't you try pda screen protect film for your lcd display? It'll cost a dollar or two if you go to bestbuy or any electronics shop. I always use protective film for any kind of LCD displays, PDA, digital camera, camcoder, iPod, pmp,....
    Even if I have a leather case in the future, I'll put a protective film for my lcd screen.
    By the way, I don't expect the practical life time as long as, let's say, 1 or 2 years for this 5G iPod. I maybe buying a 6G iPod at that time,,
    Cheers,

  • I have a few questions and I want an apple tv

    Ok I am thinking of getting the 160 GB apple TV model. My brother and I are going to ditch our cable DVR it's too expensive and we're thinking of getting the appleTV to replace it. So here's one of my questions if I hook it up to the tv in our living room we have a wifi router hooked to our computers. do we just need to log into our seperate itunes accts to access our content or do we need to create a joint acct just for the TV? Secondly if we have basic cable running thru the AppleTV can we record our shows onto the apple tv hardrive or is it just specific to itunes stuff? All replies welcome I have a 1st generation iphone which is great it well got me hooked on apple stuff I don't know why I waited so long.

    Thank you for your confirmation of my earlier post....
    To be quite honest about it, I rarely read more than the first couple of sentences of your rather long-winded comments.
    ...can you suggest a PC compatible hardware device that does what the the eyetv does for us mac users for the person asking the question.
    There is a veritable cornucopia of video capture devices available for PCs. I'm sure he'll find enough to make his head swim if he does a keyword search at Amazon.
    (sorry couldn't resist - I understand you are quite appreciative of humour)
    That's true, almost as much as you are adept at paraphrasing the answers of others and garnering points from them.

  • A few questions and advice

    Recently I swapped out my ADSL router modem for another, this caused all sorts of hassle so I put the old one back in. Since then I am having significant issues. Mostly with wireless.
    As I had not changed the airport extreme (n) I do not know why the wireless became an issue. Basically my laptop connects to the network fine with full strength but web access and local network access is variable, between normal and dead slow. I am at a loss to explain it.
    Another thing is that my ADLS modem is a draytek. And I currently have it set to DHCP and the airport to passthrough as this was what I was advised. Yet to my mind the airport extreme should take on the task of dishing out addresses as its got most things connected to it! Or put another way the draytek has one ethernet lead to the wan on the airport then from the airport my computers and a switch are connected.
    Would it make more sense to allow the airport to dish out IPs, does it make any difference?
    Any suggestions on what could have gone wrong on the wireless side would be most appreciated. For instance I was using Teleport just fine with it prior to the issue now Teleport has terrible troubles with frequent drop outs or losing control once its on the other mac leaving me with no mouse anywhere!
    One other thing are there any tools I can use to diagnose issues on the network beyond looking forlornly at the wireless bar showing full strength.

    um, no that does not seem to have fixed it after waking the macbook from sleep the speeds are rubbish again.
    If anyone is reading would an archieve install on the macbook be worth considering. Wireless from the imac seems fine. I think someting has gone pear shaped on the macbook,

  • Appletv & Time capsule question and some others.

    Hello
    My ATV is pretty much full now and so today I have taken delivery of a Time Capsule (1TB).
    Question 1: Lets assume the TC is half full this time next year. This makes it much bigger than the laptop itunes is on. How do I make it leave stuff on the ATV/TC but not synch it over to itunes?
    Question 2: My itunes crashes everytime it tries to synch with ATV. Another thread on here suggests that if you have a large amount of data that needs synching (in my case about 15 new tv episodes and a film, so a fair bit) then it works better if hardwired. Must I disable the wireless if I'm hardwiring it? If so, how? As it is currently, each time I connect up the laptop to the ATV with the ethernet cable it makes it all go incredibly wrong.
    Thanks for your help.

    iTunes crashing could indicate a problem with itunes, your network or your OS.
    Your wifi settings are disabled on the Apple tv when an ethernet connector is plugged into it.
    If you are connecting an ethernet cable directly between your PC and the Apple tv, you should be using a cross-over cable.
