Trying to understand JRE & MS JVM better

Hello,
Before I get to my question I need to give some background. Sorry for such a lengthy post.
An issue recently came up that made me realize I don't really understand the whole relationship between JRE, the MS JVM and Internet Explorer.
Here's the scenario:
- One of our internal sites has two applets that were written years ago with Java 1.2.
- Users are able to see those applets without having the Sun JRE installed. I assumed that meant they're using the MS JVM
- While moving to a new IDE we had to "upgrade" the applets to run on Java 1.4.2.09.
- The users that didn't have the Sun JRE can no longer see the applet. All they get is a grey box
- Users who have Sun JRE installed can see applet but ONLY if they have changed the options in IE to use the Sun JVM
So far so good. However, while researching this I found some users with many versions of the Sun JRE installed.
That got me thinking (here come the questions):
1) If someone has the Sun JRE installed but doesn't have any browsers selected on the Browsers tab, is it being used for ANYTHING?
2) If someone has many versions of the JRE installed, how can I tell which if any of them is actually being used?
Thanks much for any replies.
David.

1. one of the jvms will be used, sun jvm or ms jvm;
2. The latest version will be selected for you automatically.

Trying to understand iMac 10.6.8 better and find out if someone is spying on my computer.

Would like to find out if my computer is being spied on. Trying to understand info in "About my mac" means. Came across something in software Extensions...MACFramework: It says: Version: 10.8.0, Get Info String: MAC Framework Pseudoextension, SPARTA, Inc, 10.8.0, Kind: Universal,
Location: /System/Library/Extensions/System.kext/Plugins/MACFramework.kext, Kext Version: 10.8.0, Load Address: (built-in to the kernel), Valid: Yes,
Authentic: Yes, Dependencies: Satisfied.
What does this mean?
How/Where and What do I look for to see if someone is spying on my computer? And if so how do I remove it?

The Mandatory Access Control Framework is part of OS X, and is not spyware.
If you want to know if someone is spying on your computer, install Little Snitch. It will tell you when anything new is trying to send something outside of your system.

Trying to understand Android OS updates delays

This is not another hate mail, it´s more about trying to understand the facts and motives regarding the OS updates (or lack of).
Hopefully this material will arrive at someone from Sony with enough power to do something about it.
Ever since I can remember, Sony has been THE brand for electronics. I can´t remember a TV or VCR in my house that it wasn´t Sony, and they lasted for LOTS of years.
When a couple years ago I finally had the money (and the need) for a Smartphone, i chose the X10 Mini, which is a great little phone from a great brand, but it´s stuck at Android 2.1... which makes it a crippled android nowadays...
It really bothered me the lack of OS updates, so I chose to buy a Galaxy Nexus, but it´s really expensive in my country. So my second option was a Galaxy Ace 2, but they haven´t arrived to my country yet, so I went with my third option: Xperia Sola, knowing beforehand that it´s a great phone, a great brand, but I might get slow OS updates.
I bought it about 10 days ago when I saw they were starting to roll out the updates.
10 days later I still don´t have my update. And not only that, but I don´t see much light at the end of the tunnel...
I found a thread with the SI numbers that were updated, and there were a bunch on Oct 1, another bunch on Oct 4, and one code on Oct 8, and no other update since...
I also read that those who did get the update, were having bugs with the OS, and also found threads from other Xperia models, whose updates began rolling 3 months ago, and there is still people who hasn´t gotten the update...
As a customer, and a owner/CEO of a small company, I have a really hard time understanding how a HUGE company like Sony can be making such mistakes...
I have been thinking objective reasons, and I can only think of one. I know it´s a wild guess, but I´m starting to think that our salvation might be the very thing that means our condemnation: CYANOGENMOD!!!
Think about it: Why would Sony spend more money hiring twice as much programmers, when they can make only one update per phone, and sit down and see how CM releases begin to appear, for all tastes and needs. And... IT´s FREE!!!
Also, if there is a software related problem (way more likely than a hardware problem), then the CM developers take the fall, instead of Sony. And I´m beginning to see custom OS installers that are more user friendly, so it might be something that they take in accout when neglecting OS updates.
If that´s the line Sony is following, it´s a very risky move and it won´t work. Sony Mobile will crash and burn, but it´s still a better business plan that "let´s get lazy and make ULTRA slow updates so we don´t spend a lot of money programming".
If you can´t afford more programmers, stop including so much bells and whistles and make your OS near vanilla. Include a couple of Xperia menus, a custom theme and voila!
The main reason I wanted the Galaxy Nexus is Vanilla OS, which means inmediate OS updates. Sony on the other hand, takes a year or two to release it after its launch. If they release it at all...
Another though... why not stop making that many different phones! Really! There are like 5 Xperia models i can´t tell one from the other... even with specs side by side!
You are trying to make too many phones and you are failing with all of them! (Software and software updates are also part of the phone, one of the most importants...)
I know hiring programmers is expensive, but you are sacrificing one of the most expensive values for a company EVER: Customer credibility! Which as you know better than me, takes years to create.
If Apple had problems with carriers and code aprooving and stuff, they might get away with it, becouse they alone have all the devices. If iOS 6 is delayed a few months, it´s delayed for everyone, and besides Apple fanboys rarely complain about Mac products, but Android is a more independent and educated market.
I´m not saying that Apple users are ignorant, not at all, but I´m pretty sure most iPhone owners don´t even know what processor or how much RAM their phone has. They just "swallow" the Apple Way of Life. (it´s a good phone becouse Apple says so).
The Android user on the other side, because of the fragmentation of the market, has many brands and models to choose from. An Android user about to buy a new phone will most likely go online looking for different models, specs, reviews in webs and forums...etc.
You can´t say "I don´t know how HTC and other companies get their updates so soon, but we take a lot more becouse Google and the Operators must aproove the code.", because there are many other brands that have exactly the same difficulties or more, since they are smaller, and we can SEE online that they are indeed delivering solid and relativly fast updates.
Did we miss something? Does HTC use Witchcraft to get their code aprooved?
My underlying point is this: You are getting lazy... VERY lazy with software programming for your phones, and WE KNOW IT!
It´s not the "difficulties" you claim, becouse every brand has those difficulties.
This isn´t 1999 you know. We are in the information age. If you lie to us and tell us that your phones have the latest OS, I can go online and see that you don´t (Hello!!!). If I see that the company lies to it´s customers, I will stop buying their products. If I´m so dissapointed with how Sony handles OS updates and their customers queries about it, then I want for the first time ever to sell my Cell Phone becouse I´m not happy with it, or the brand behind it.
We also live in the "Here and now" age. You can´t expect your customers to read about new Android releases on news and blogs, and wait YEARS with arms crossed waiting for their update... The world doesn´t work like that. Not anymore at least...
It´s not a matter of how many recources you have, it´s about how you use and balance them. GIVE MORE IMPORTANCE TO SOFTWARE UPDATES! IT´S WAY MORE IMPORTANT THAT YOU THINK! LISTEN TO YOUR CUSTOMERS!!!
You guys are Sony are smart and design great products, but you are not GOD! You are not our wife, no one has sworn alliagence to you.
If you stop giving us good products and start lying to us, we hate you and stop giving you our money. Simple as that.
My sola is beatiful, I love the design, the screen, the hardware... but it hasn´t been updated yet to 4.0, not to mention 4.1, which REALLY is the latest version... so stop advertising that your phones have the latest Android OS, unless you want angry customers switching to other companies, which you are getting.
I also read some stories that Androind 4.0 was announced for the Xperia PLAY, and then it was called off... Do you have any idea how pissed I would be and ripped off I would be if I bought my phone based in that information and then you say it won´t be available?
Well, actually right now my possition is worse, since you SAY you will update my phone, but you don´t say when, and I read online about people still not getting their updates months after the rollout started, so I´m in the limbo right now...
As a company, one of the worse things you can do is calling your customers stupid, and when I see the answers you give in this forum, then I feel insulted. I feel like they are talking to an idiot or ignorant person with the so called "diplomatic" answers, which are basicly empty excuses for not doing your job right.
You gave us the frikking CDs, DVDs and Blu-Rays!!! Don´t tell us you can´t tweak an already built OS in a year!
I really hope you change their OS update policies really soon, before you lose the already small cellphone market share you have, or at least change your P.R. and C.M. policies towards a more open one.
We all are humans and make mistakes, but we customers really appreciate honesty and truth.
Have an open conversation with your customers! Don´t lie about your shortcomings! Accept then and ask the community to help you solve them, ask them what they biggest problems are, what features are most important to them, how often do they expect updates... LISTEN TO THEM!!
"Succes is a meneace. It tricks smart people into thinking they can´t lose."
Ps: Nothing personal with the mods from this forum, I´m not killing the messenger, I know that you can ONLY give the info you are allowed to give, and even if you wanted, you probably don´t know the answers yourself, since you work in the Communications department, not Developement or anything technical, and if you can't give any given info, then they probably won´t give it to you either... My message is to the company as a whole. I just hope you will be a good messenger and give this to whoever needs to read it.

My bad, it´s closer to 40 the number of phones released hehe
I know it´s all about money, and I know Sony is obligated to neglect users who haven´t given them money after an x ammount of time. However, it´s not a matter of making the phones obsolete earlier, so the users want to buy a new phone faster and therefore getting more money.
A person will buy a new phone when he/she has the money to do so and wants to do so.
It´s not a matter of WHEN. It´s a matter of WHAT.
The question is not "When will that user buy a new phone?", but rather "When that user buys a new phone, whenever that is, what phone will it be?"
I have a love/hate relationship with Apple. I would never use a iPhone. I would love having any Mac, if someone gives it to me, but I would never spend my harn earned dollars on such an overpriced piece of hardware over general principals.
However, i do recognice that Steve Jobs was a business genius. Weather you like or love his ideas and methods, he turned a garage project into the biggest company in the world, with a market value higher than Exxon with 1/3 of it´s assets.
Apple is a money making machine, and that is where the "hate" part of my relationship comes from.
However, it surprised me a lot to see that they released iOS 6 for the iPhone 3GS, released in 2008!
That get´s you thinking, that inside all that "SELL NOW" culture Apple is, they also support their older devices that people bought years ago but can't buy a new phone now. However, when they can do it, it will surely be another iPhone. Because they FEEL that the company listens and cares for them.
Also if you jump from iOS 6 on the 3 GS to a brand new iPhone 5, the transition will be virtually non-existant, except for Siri and a couple of features.
However jumping from Android 1.5 or 2.1 to Jelly Bean, might not be so easy on some users, making them more likely to give iPhone a shot.
Since they have to adapt to another phone anyway, they might as well try the apple...
And for old users, it gives people a sense of continuity and care about the user. Otherwise we feel like being kicked out of a restaurant right after we payed the bill.

Trying to understand the Serialization interface

Im trying to understand the Serialization of objects?
As an example, I create a Library class that implements Serializable, that stores a collection of Book objects
If I am only looking at saving a Library object to file, does the Book class require Serialization also or just the Library?
I have read the API on serialization, no answer there, if it is it's not easy to understand or read into the API...

There are some really important things to know about when doing serialization. For example one important thing to know about that not is mentioned here is that your serializable classes must define its own private static final long serialVersionUID because if you not do that will you not be able to deserialize (read in) the data you have saved later if you change anything in your serializable class. It is a bit tricky to manage files to which you have serialized different versions of your class, that is versions where you have added more serializable members to the class after you have serialized files. Well, it is not a problem if you don´t care if you have to type in all your saved data again every time you change anything instead of deserialize it (read it) from your file of course :)
Situations like this may be handled if you define your own (private) writeObject(ObjectOutputStream) and your own readObject(ObjectInputStream) methods in your serializable class but there is a better a lot smarter way to handle this. Use of a serialization proxy! how to use that is described in the excellent book Effective Java 2nd ed. With a serialzation proxy for every serializable version of your class (where a version corresponds to a version of your class with differences in its number of serializable members) may your class deserialize data written from elder versions of your class also. Actually is it first since I read the last chapter of Effective Java that I think I have myself begin to understand serialization well enough and I recommend you to do the same to learn how to use serialization in practice.

Trying to understand and learn how to use btrfs

I have been the past days trying to get my head around how btrfs works
I have been trying tools like mkinitcpio-btrfs (very poorly documented) and now, if i list the subvolumes i have in certain volume (/) i see i have 4 subvolumes that have been created while playing around.
If i try to delete them with "sudo btrfs subvolume delete __active", for example, I get a "ERROR: Error accessing '__active'
What am I doing wrong?
Also, I cannot get the whole idea about the difference between snapshots and subvolumes, i mean, a snapshot should be a directory that saves the changes made on the fs, s, if you want to roll back those changes, you just have to make btrfs "forget" the changes stored in that directory and move along, but I cannot take the idea of the subvolume thing.....
As btrfs is quite experimental and the wikis are not noob-proof still, I'd appreciate if someone gave me a hand trying to understand these concept...
For the moment, I'm just using it on a test computer and on a personal laptop with no fear of data loss,.
Any help is welcome
Thanks!

I honestly think it is probably a better idea to not use mkinitpcio-btrfs. As mentioned above, it is poorly documented, and for me it has never worked right (if at all). It is an unofficial AUR package, and unfortunately our wiki still seems to give the false impression that using this package is the way to user btrfs with Arch.
The way I have my system set up is that in subvolid=0 (the root of the btrfs filesystem) I have a rootfs subvolume and a home subvolume (there are others, but these are what primarily make up my system). So in my fstab, I basically have two nearly identical lines, but one has no subvol specified and is mounted at /, and the other has 'subvol=home' mounted at /home.
So in order to make it so that I can change the root filesystem as I please, instead of having the / fstab entry specify the subvolume, I put it in the kernel command line. That is, I have 'rootflags=subvol=rootfs' in the kernel command line. So if I want to change it, I simply change the path to one of the snapshots.
Just remember that if you are one who likes a custom kernel, it is likely that you will have to have an initamfs no matter what you compile into your kernel. For one thing, the kernel has no mechanism for scanning for multiple device btrfs filesystems. But also, I have read that the kernel itself cannot handle the rootflags kernel command line argument.
Oracle Linux does something interesting with their default setup. They are not a rolling release, so this probably wouldn't work so well in Arch Linux, but they actually install the root filesystem (I think it is actually done to subvolid=0) and then after installation of the packages, a snapshot of the root filesystem is made, and the system is setup to boot off of that snapshot. So it is almost like having an overlayfs on openwrt. There is always a copy of the original system, and and changes that are being made are being done "on top" of the original. So in the event of an emergency, yo can always get back to the original working state.
If you put your root filesystem on something other than the root of the btrfs filesystem (which you should, as it makes the whole setup much more flexible), then you should also set up a mountpoint somewhere to give administrator access to the filesystem from subvolid=0. For example, I have an autofs mountpoint at /var/lib/btrfs-root. chose that spot because /var/lib is where devtools puts the clean chroot. So it seemed as reasonable a place as any.
You should go to the btrfs wiki, and peruse through the stuff there... not our wiki, but the actual btrfs one, as our wiki is pretty sparse. There is not all that much content there (not like the Arch wiki), but it does cover the features pretty well. I mean, there is certainly quite a lot for being information on only a single filesystem, but it shouldn't take you too long to get through it. There are a few links to articles about midway down the front page. What really gave me a better grasp of getting started with btrfs were the ones titled "How I Got Started with the Btrfs Filesystem for Oracle Linux" and "How I Use the Advanced Capabilities of Btrfs".

Trying to understand hashCode( )

Hello again, I'm trying to understand the hashCode( ) method. I have a textbook which describes it this way:
"A hashcode is a value that uniquely identifies an individual object. For example, you could use the memory address of an object as it's hashcode if you wanted. It's used as a key in the standard java.util.Hashtable[i] class."
Please forgive me if this emplies that I may be a bit slow with this, but this explanation is too vague for me to grasph what's going on here. Can someone thoroughly explain (in a non scientific way), how and why this method is used?
Thanks in advance.

I thought the examples I provided might give you an idea why the hashCode method is useful. I'll try one more brief one, and if that doesn't connect that spare wire to the light bulb over your head, then I'll have to agree with schapel and suggest that you study up on your CS theory.
This will be a really crocked up example, and you could skirt some of the issues with better design, but it's a valid example nonetheless.
You run a greenhouse or an arboretum or something. You've got 25,000 Tree objects (forget their subclasses for now). Trees have properties like species, name (I don't know why you'd name a tree--just bear with me), location, age, medical history. You're going to put your Trees into a java.util.Set, so you've got a collection with one reference to each tree. However, you're getting overlapping subsets of your trees from various sources--that is getAllElms() returns some trees that are also in getAllOlderThan(10). You need to combine all those results into a 1-each collection of Trees.
When you go to add an Object to the Set, the Set has to first check if that Object is already present. The Set implementation could iterate over all its elements and call equals() to see if that Object is already there. Or, it could first get the hashCode (let's say you've implemented hashCode to return the xor of the species and the age). So, maybe 100 out of your 25,000 trees are 50 yeard old Elms. Internally, if the Set implementation keeps a mapping from hashCode to an array of Trees with that hashcode, then it only has to copmare to those 100 trees that match, rather than all 25,000.
As I said, this is a cheezy example. One problem is that if trees are mutable, this Set implementation won't work, since the Set won't know that a Tree's internal values (and hence, possibly, its hashCode) have changed.
Is is making any sense yet?
Okay so please help me understand this rudimentary,
logical reason for wanting to use a hashCode( )? Say
I create a top level class called "Plant.java". Now
from that class I create a subclass called Tree.java
from which several other subclasses and objects are
created. Help me gain a basic understanding of why
and how the hashCode( ) method might be beneficial.
(lol... I feel sort of like I've opened up a cool new
electronic toy, I'm standing here with a "spare wire
in my hand wondering what the heck this part is
for?")
Thanks again for your help. I really apprecitate it.

Type problem - Class Cast Exception - trying to understand

hello,
i get a Class cast exception in the following code.
interface Foo {}
class Alpha implements Foo {}
class Beta extends Alpha {}
class Delta extends Beta {
public static void main( String[] args ) {
Beta x = new Beta();
Beta b = (Beta)(Alpha)x; //fine
Foo f = (Delta)x; //CCE
Object ob = new Object();
String s = new String();
ob = s; //fine, no need of case
s = (String)ob; //needs a castI was just thinking, implicitly Delta and Beta both of them IS-A Foo, and assigning x to a type foo shouldnt be a problem(while making it refer to the Delta class) so, what could cause the CCE ?
I would appreciate if someone could please help me understand this.
Rgds

Hi.
Assigning your "x" to a variable typed Foo is not a problem. The problem is that you are trying to cast an instance of Beta ("x") into type Delta which is not possible. Every Delta is a Beta, but not every Beta will be a Delta!
Simple as that.
Bye.

Trying to Understand Color Management

The title should have read, "Trying to Understand Color Management: ProPhoto RGB vs, Adobe RGB (1998) my monitor, a printer and everything in between." Actually I could not come up with a title short enough to describe my question and even this one is not too good. Here goes: The more I read about Color Management the more I understand but also the more I get confused so I thouht the best way for me to understnand is perhaps for me to ask the question my way for my situation.
I do not own an expensve monitor, I'd say middle of the road. It is not calibrated by hardware or any sophisticated method. I use a simple software and that's it. As to my printer it isn't even a proper Photo filter. My editing of photos is mainly for myself--people either view my photos on the net or on my monitor. At times I print photos on my printer and at times I print them at a Print Shop. My philosophy is this. I am aware that what I see on my monitor may not look the same on someone else's monitor, and though I would definitely like if it it were possible, it doesn't bother me that much. What I do care about is for my photos to come close enough to what I want them to be on print. In other words when the time comes for me to get the best colors possible from a print. Note here that I am not even that concerned with color accuracy (My monitor colors equalling print colors since I know I would need a much better monitor and a calibrated one to do so--accurately compare) but more rather concerned with color detail. What concerns me, is come that day when I do need to make a good print (or afford a good monitor/printer) then I have as much to work with as possible. This leads me to think that therefore working with ProPhoto RGB is the best method to work with and then scale down according to needs (scale down for web viewing for example). So I thought was the solution, but elsewhere I read that using ProPhoto RGB with a non-pro monitor like mine may actually works against me, hence me getting confused, not understanding why this would be so and me coming here. My goal, my objective is this: Should I one day want to print large images to present to a gallery or create a book of my own then I want my photos at that point in time to be the best they can be--the present doesn't worry me much .Do I make any sense?
BTW if it matters any I have CS6.

To all of you thanks. First off yes, I now have begun shooting in RAW. As to my future being secure because of me doing so let me just say that once I work on a photo I don't like the idea of going back to the original since hours may have been spent working on it and once having done so the original raw is deleted--a tiff or psd remains. As to, "You 're using way too much club for your hole right now." I loved reading this sentence :-) You wanna elaborate? As to the rest, monitor/printer. Here's the story: I move aroud alot, and I mean a lot in other words I may be here for 6 months and then move and 6 months later move again. What this means is that a printer does not follow me, at times even my monitor will not follow me so no printer calbration is ever taken into consideration but yes I have used software monitor calibration. Having said this I must admit that time and again I have not seen any really noticeale difference (yes i have but only ever so slight) after calibrating a monitor (As mentioned my monitors, because of my moving are usually middle of the road and limited one thing I know is that 32bits per pixel is a good thing). As to, "At this point ....you.....really don't understand what you are doing." You are correct--absolutely-- that is why I mentioned me doing a lot of reading etc. etc. Thanks for you link btw.
Among the things I am reading are, "Color Confidence Digital Photogs Guide to Color Management", "Color Management for Photographers -Hands on Techniques for Photoshop Users", "Mastering Digital Printing - Digital Process and Print Series" and "Real World Color Management - Industrial Strength Production Techniques" And just to show you how deep my ignorance still is, What did you mean by 'non-profiled display' or better still how does one profile a display?

Trying to understand upgrade fee

I have spent the better part of the last three months trying to understand why one has to pay an upgrade fee. If we renew the contract and buy another phone, then why do we need to spend an additional $30 for an "enttled" upgrade? Why not build it into the phone price if everyone has to pay it? It seems petty if you deal with Verizon Wireless on a longterm basis

Why do doctors charge multiple co-pays instead of just adding that price into the outrageous charges they submitted to the insurance carriers?
They charge the upgrade fee because you are purchasing a phone that costs $500-$800 for less that 1/4 the cost of the phone.
You see you charge co-pays separate from your charges. Verizon does the same. So this should not be an issue.
Good Luck

Mac newbie trying to understand

I haven't learned to think in Mac yet. I'm trying to understand what actually happens to the files that I have imported from my memory card into iphoto and then exported to another folder on my hard drive for use in other applications or on a Windows PC. Are the files moved from the iphoto library and then tracked in iphoto or are they copied to the new folder thus creating two copies on the hard drive? Any of the above?
I am trying to avoid creating duplicates of the originals in order to save space and would like to understand this before I go much further and wind up with a huge mess. I'm thinking maybe I should use image capture to get the photos from the card to a folder and then import into iphoto so the originals would be more readily available for burning cds/dvds for use use in Windows as I will be doing that a lot. How would that work?
That's probably about as clear as mud. Anybody understand and can educate me? By the way, love my iMac.
Thanks.

Welcome to the Apple user to user assistance forums
And welcome to the Mac
while you will find the Mac very intuitive and easy to use it is different from a PC and there is a learning curve - the Apple tutorials are very helpful - see the right hand column for a list by major topic - http://www.apple.com/startpage/
I'm trying to understand what actually happens to the files that I have imported from my memory card into iphoto and then exported to another folder on my hard drive for use in other applications or on a Windows PC. Are the files moved from the iphoto library
By default (and strongly recommended) the imported photos are copied to the iPhoto library -- there is an option not to do this but it can be extremely problematic and unless you are a very experienced user it is strongly recommended that you use the default of copying all imported photos to the iPhoto library
and then tracked in iphoto
Yes - by default
or are they copied to the new folder thus creating two copies on the hard drive?
The original is left alone unless you choose to have iPhoto delete the photos form the camera after importing (it is best not to have iPhoto do this but to use the camera to reformat the card once everything is firmly in iPhoto and the camera is properly disconnected. Once you have imported the photos to iPhoto you can delete the original that is outside of iPhoto
I am trying to avoid creating duplicates of the originals in order to save space and would like to understand this before I go much further and wind up with a huge mess. I'm thinking maybe I should use image capture to get the photos from the card to a folder and then import into iphoto so the originals would be more readily available for burning cds/dvds for use use in Windows as I will be doing that a lot. How would that work?
This will create two copies of each original and is unnecessary - it is better to export the photos you want to use and delete the exported versions after you use them.

I am trying to understand my Console System Log Queries, but not having much luck!!

I am trying to understand my MB late 2011, much better than I do, whilst looking through my console messages, I realised I don't have a clue as too whats what, I seem to be getting a lot of system errors - Is this normal?
Why are Mac Books soooo complicated - !
I would copy and paste my system messages - but once again I am 2 thick - don't know which bits - if any would need editing!
Any advise would be a great help.
Thankyou in advance.

You would use the Input button on your remote to set the Input to RGB PC and you'll also need audio cables to the TV because the Mini-DVI does not carry audio using a 3.5mm stereo headphone jack to RCA sound plug. You attach it from the headphone jack of your MacBook to the appropriate input plug on your TV.
When you first hook it up it will probably have the display set in Extended Desktop mode. The Menu Bar and Dock will be on the MacBook display and your background screen on the TV but you can move the cursor onto the TV screen.
In System Preferences>Display on the MacBook screen there should be an Arrangement tab when you have the MacBook hooked up to the TV and both screens working. When you click the Arrangement tab do you see two monitors side by side? One of them will have a Menu Bar at the top. Just click on the Menu Bar and drag it to the second monitor. That will make the second monitor your main screen. You can now use your MacBook in Clamshell Mode with a wired or Bluetooth keyboard and mouse. http://support.apple.com/kb/HT3131 When you disconnect from the TV your Menu Bar will automatically change back to the MacBook.
Or if you want to work on the MacBook screen while showing it on a TV you can check the Mirror Display box on the lower left hand side of the Arrangement tab under the two monitors box.

Hello, World - trying to understand the steps

Hello, Experts!
I am pretty new to Flash Development, so I am trying to understand how to implement the following steps using Flash environment
http://pdfdevjunkie.host.adobe.com/00_helloWorld.shtml
Step 1: Create the top level object. Use a "Module" rather than an "Application" and implement the "acrobat.collection.INavigator" interface. The INavigator interface enables the initial hand shake with the Acrobat ActionScript API. Its only member is the set host function, which your application implements. During the initialize cycle, the Acrobat ActionScript API invokes your set host function. Your set host function then initializes itself, can add event listeners, and performs other setup tasks.Your code might look something like this.
<mx:Module xmlns:mx="http://www.adobe.com/2006/mxml" implements="acrobat.collection.INavigator" height="100%" width="100%" horizontalScrollPolicy="off" verticalScrollPolicy="off" >
Step 2: Create your user interface elements. In this example, I'm using a "DataGrid" which is overkill for a simple list but I'm going to expand on this example in the future. Also notice that I'm using "fileName" in the dataField. The "fileName" is a property of an item in the PDF Portfolio "items" collection. Later when we set the dataProvider of the DataGrid, the grid will fill with the fileNames of the files in the Portfolio.
<mx:DataGrid id="itemList" initialize="onInitialize()" width="350" rowCount="12"> <mx:columns> <mx:DataGridColumn dataField="fileName" headerText="Name"/> </mx:columns> </mx:DataGrid>
Step 3: Respond to the "initialize" event during the creation of your interface components. This is important because there is no coordination of the Flash Player's initialization of your UI components and the set host(), so these two important milestone events in your Navigator's startup phase could occur in either order. The gist of a good way to handler this race condition is to have both your INavigator.set host() implementation and your initialize() or creationComplete() handler both funnel into a common function that starts interacting with the collection only after you have a non-null host and an initialized UI. You'll see in the code samples below and in step 4, both events funnel into the "startEverything()" function. I'll duscuss that function in the 5th step.
               private function onInitialize():void { _listInitialized = true; startEverything(); }

Trying to understand OIM - Please help

Hello All,
I am pretty new to OIM, just trying to understand how OIM works. For the past 4 years I was in Sun IdM and planning to switch over to OIM.
I read some documentation, I think OIM will perform basic provisioning and it contains out of box connectors to do basic provisoning. I have some questions can anybody please help
- Sun IdM uses Express language to develop custom workflows or forms, in OIM to develop workflows which language did you use, is it Java or any other language?
- If I want to provision users on AS/400, HP Open VMS or AIX systems, how can I do that I don't see any out of box connectors for these resources, so in order to integrate these resources do we need to write our own custom connectors?
- If the out of box connector does not support a specific function on a resource what are the options do we have? for example if the AD connector does not support to delete the exchange mailbox, how your going to perform this in OIM? Do we need to write a Java code for this?
- How much Java coding is necessary in OIM?
- Is OIM supports role based provisioning?
Please share any information.
Thanks in advance.

Sun IdM uses Express language to develop custom workflows or forms, in OIM to develop workflows which language did you use, is it Java or any other language?
- JAVA
If I want to provision users on AS/400, HP Open VMS or AIX systems, how can I do that I don't see any out of box connectors for these resources, so in order to integrate these resources do we need to write our own custom connectors?
- If OOTB connectors are not available then you'll have build you own connector as per Target Resource.
If the out of box connector does not support a specific function on a resource what are the options do we have?
- You'll have customize their connector as per your requirements or write your own
How much Java coding is necessary in OIM?
- We can't calculate how much java. It's totally depends on requirements how much code you'll ahve to write. But everything will be done using Java only.
- Is OIM supports role based provisioning?
Here Group represent Role. At a small scale it supports. But for large scale you'll have to use Oracle Role Manager as you do in Sun Role Manager.

Trying to understand, being prompted the file compression rules on saving, or not

Hello,
I'm trying to understand something, could I ask for your help, please ?
After working on a jpg file, when I want to save it, still as jpg, with my Photoshop CS5,
- sometimes photoshop will just save the picture, and it's done
- sometimes photoshop will show me the compression dialog, "JPEG Options", in which I can choose the compression ratio, the format options (baseline, baseline optimized, progressive), and have an estimation of the total file size
While not being prompted any dialog is simpler, and I'll then simply assume Photoshop decides to retain the current image's compression and format rules, I must say I like to be in control, and I'd like to know under what form the file is being saved without having to resort to the much more complex "Save For Web" menu.
Please, would you know WHAT "triggers" the appearance of the JPEG Options when we close/save a jpeg file, in photoshop ? What makes this menu not to appear, what makes it appear ?
If there are trivial file operations/changes/filters that necessarily trigger its appearance when we want to save, something like that ? I've tried a variety of these, but I still can't figure it out, sometimes it shows in the end, and sometimes it doesn't.
Thank you very much if you can help me
Kind regards,
Oliver

@ c.pfaffenbichler
These are images from various sources, not just one.
I'm deliberately excluding Save For Web, this completely re-processes everything.
My purpose, precisely, is to know when photoshop takes the decision to retain the image's "rules", and when photoshop decides to pose us the question, how do we want it saved.
Simply taking a jpeg image, doing stuff on it, and hitting control-w to close the window, and seeing if it will be an
- «OK, sure, do you want to save ? You clicked OK to confirm you wanted the changes saved ? Good, now it's closed» or a
- «please sir, how would you like your image saved, tell me the compression ratio and the format options, thank you»
