Trying to understand LEDs on a WRT54G

Hi,
What do the Internet and Wireless LEDs mean on my WRT54G? The WLAN LED is on constantly, even though I don't believe anyone is using it. Also, the Internet LED is on constantly, with an occasional blink, even though I (connected through a wire to the router) am doing nothing at the time.What do these lights mean, and how can I see if there is any wireless traffic on my router, in fact?
Thanks,
dn
Solved!
Go to Solution.

If the WLAN Light on your router is LID, this means the Wireless Activity is ON. And your Router is Transmitting Wireless Signals.
If the Internet Light is Lid, this means the Connection between your Modem and Router is Establish and the computers which are connected they should be able to go online.
If you wish you can secure your Wireless Network. Here are some steps which you can fallow on your router.
Open an Internet Explorer browser page on your wired computer(desktop).In the address bar type - 192.168.1.1
Leave username blank & in password use admin in lower case...
For Wireless Settings, please do the following : -
Click on the Wireless tab
-Wireless Network mode should be mixed...
-Provide a unique name in the Wireless Network Name (SSID) box in order to differentiate your network from your neighbours network...
- Set the Wireless channel to 11-2.462GHz...Wireless SSID broadcast should be Enabled and then click on Save Settings...
Please make a note of Wireless Network Name (SSID) as this is the Network Identifier...
For Wireless Security : -
Click on the Sub tab under Wireless > Wireless Security...
Change the Wireless security mode to WEP, Encryption should be 64 bits.Leave the passphrase blank, don't type in anything...Under WEP Key 1 type in any 10 numbers please(numbers only and no letters eg: your 10 digit phone number) and click on save settings...Please make a note of WEP Key 1 as this is the Security Key for the Wireless Network...
Click on Advanced Wireless Settings
Change the Beacon Interval to 75 >>Change the Fragmentation Threshold to 2304, Change the RTS Threshold to 2304 >>Click on "Save Settings"...
Now see if you can locate your Wireless Network and attempt to connect...

Trying to understand QT Export's size choices

Hey guys, I'm hoping to see if you guys can shed some light on a little thing - it irks me that I don't know this. It's not expressly about an FCE feature, it's more part of the Quicktime Export module, but I figured you experts here have experience with this:
When I choose *Export-->Using Quicktime Conversion* and bring up the dialog, the Size button brings up a pop-up menu of two groups of frame size choices (see enclosed image):
!http://www.geoffkaiser.com/various/export.jpg!
It would look like there's some redundancy here. So for example, what's the difference if I choose "1920x1080 HD" in the upper half or "HD 1920x1080 16:9" in the lower half ?? Are these two groups different somehow?
Just trying to understand....
thanks!

Wow, thank you Martin; that set me off on a google path that seems to have led to the answer.
According to this document from Apple, Quicktime 7.1 introduced the ability to display different 'aperture' settings for showing a movie file. In short, this means that during display, it can crop along the edges of a movie when assuming that the compressor's encoder would produce artifacts out there along the edge. Apparently it can only do this if the movie was encoded with that parameter, hence the extended preset menu in the QT export dialog. The menu's bottom half presets seem to be the ones that add that ability.
This screenshot I took shows two rendered output QT files, both from a 1920x1080 sequence in FCE4. The "Sequence 2.1" used the '1920x1080 HD' preset from the upper half, and "Sequence 2.2" used the 'HD 1280x1080 16:9' preset from the bottom half. I set the two movies to display at the same size, and when bringing up Movie Properties in both and selecting the "Clean" setting under Presentation-->Conform Aperture, the movie from the 'HD 1280x1080 16:9' preset (on the right) becomes cropped (if you look closely). Choosing "Clean" (or any other setting) on the first file (on the left) has no effect.
Soooo, apparently that's it; choosing the presets in the bottom half net you an extra display feature (that can be toggled on or off) when using QuickTime Player 7.1 or higher. Of course there's nothing in the QT Export dialog to tell you this. But Martin I appreciate your efforts in investigating the outputs of each, as it led me to the answer.

Is there a Thunderbird manual? I'm trying to understand all the View/Threads options.

I'm learning Thunderbird, hoping to adopt it as my mail client (can't keep Eudora afloat any more). The forums are not efficient for learning it. Right now I'm trying to understand all the View/Threads options, but tomorrow it will be something else.

Thanks, those are helpful. The first one doesn't explain threads options but it led me to https://github.com/protz/GMail-Conversation-View/wiki/What-is-threading, which told me to do View > Sort by > Threaded (I had only tried View > Threads > ...). It also explains threading by message ID, whereas Eudora seems to do it only by subject line.
Neither reference explains the options under View > Threads > ... but I'll figure it out by trial & error.
The second reference led to http://www.nidelven-it.no/documentation/thunderbird/introduction-to-thunderbird, which also looks helpful.

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 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 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»

UTL_HTTP.end_of_body Exception Error. Trying to Understand the Reason Why?

I have the following PLSQL Function that returns a End_of_body Error. This started when we migrated from 10g to 11g. It is simple enough to capture so the error does not stop the Function Flow, but the error causes the OCI driver in OBIEE to error, which prevents the use of OBIEE IBOT to execute. Trying to understand why this error is occurring..not sure if we have a permissions issue on the UTL_HTTP Package or what?
Anyone seen this problem in 11g? Suggests on resolving would be great. Thanks.

[SOLVED] Trying to understand the "size on disk" concept

Hi all,
I was trying to understand the difference between "size" and "size on disk".
A google search gave plenty of results and I thought I got a clear idea about
it.. All data is stored in small chunks of a fixed size depending on the
filesystem and the last chunk is going to have some wasted space which
will *have* to be allocated.. Thus the extra space on disk.
However I'm still confused.. When I look at my home folder, the size on disk
is more than 320 GB, where as my partition is actually less than 80 GB, so
I guess I'm missing something.. Could somebody explain to me what does
320 GB of 'size on disk' means?
Thanks a lot in advance..

Hi all,
Thank you for your replies.. My file manager is indeed pcman fm and
indeed it seems to be an issue.. In b4data's link the last post reads:
B-Con wrote:
FWIW, I found the problem. (This bug is still persistent in v0.9.9.)
My (new) PCManFM bug report is here: http://sourceforge.net/tracker/index.ph … tid=801864
I submitted a potential patch here: http://sourceforge.net/tracker/?func=de … tid=801866
Bottom line is that the file's block size and block count data from the file's inode wasn't being interpreted and used properly. The bug is in PCManFM, not any dependent libraries. Details are in the bug report.
Since PCManFM is highly used by the Arch community, I figured I should post an update here so that there's some record of it in our community. Hopefully this gets addressed by the developer(s) relatively soon. :-)
I guess that pretty much explains things.. And I think I did understand the 'size on disk' concept
anyway
Thanks again!

So as you can see, soundcore's already loaded, so why do I have to explicitly load it again to get the mic to work?
Once I add soundcore to my MODULES array and reboot, the lsmod output is also the same as above.
So my question is -- what does the explicit loading of soundcore do, that is not done by auto-loading of that module?

Oh... since your topic is Trying to understand the sound system, that puts you (and me) inside the whole world's population... chuckle. But I thought I'd pass along a document written by probably "The" main ALSA developer that I totally stumbled across just 3 days ago.
Go here:
http://kernel.org/pub/linux/kernel/people/tiwai/docs/
and download the flavor of your choice of the "HD-Audio" document, or simply view it online. It documents the deepest dive into the current ALSA snd_hda_* layers and issues that I've found to date (but still leaves me wanting).
Why that document isn't plastered across the interwebs is beyond me. I only get 11 hits when I search for it... such are the secrets of the ALSA world I guess.

Trying to understand the MODEL clause

Hi All,
I'm finally biting the bullet and learning how to use the model clause, but I'm having a bit of trouble.
The following example data comes from a book "Advanced CQL Functions in Oracle 10g".
with sales1 as (select 'blueberries' product
                      ,'pensacola' location
                      ,9000 amount
                      ,2001 year
                  from dual
                union all
                select 'cotton', 'pensacola',16000,2001 from dual
                union all
                select 'lumber','pensacola',3500,2001 from dual
                union all
                select 'cotton','mobile',24000,2001 from dual
                union all
                select 'lumber', 'mobile',2800,2001 from dual
                union all
                select 'plastic','mobile',32000,2001 from dual
                union all
                select 'blueberries','pensacola',9000,2002 from dual
                union all
                select 'cotton', 'pensacola',16000,2002 from dual
                union all
                select 'lumber','pensacola',3500,2002 from dual
                union all
                select 'cotton','mobile',24000,2002 from dual
                union all
                select 'lumber', 'mobile',2800,2002 from dual
                union all
                select 'plastic','mobile',32000,2002 from dual
                union all
                select 'blueberries','pensacola',9000,2003 from dual
                union all
                select 'cotton', 'pensacola',16000,2003 from dual
                union all
                select 'lumber','pensacola',3500,2003 from dual
                union all
                select 'cotton','mobile',24000,2003 from dual
                union all
                select 'lumber', 'mobile',2800,2003 from dual
                union all
                select 'plastic','mobile',32000,2003 from dual
select location, product, year, s
from sales1
model
--return updated rows
partition by (product)
dimension by (location,year)
measures (amount s) ignore nav
(s['pensacola',2003] = sum(s)['pensacola',cv() > cv()-1])I would have expected the measures clause to return the sum of all amounts for pensacola where the year > 2003 - 1 = 2002. which would make the total for [blueberries,2003] = 1800, but instead it comes out as 27000, apparently summing all values for blueberries for that partition.... equivalent to sum(s)['pensacola',ANY].
how would I go about making s['pensacola',2003] = the sum of itself plus the previous row?
I realise I can do
s['pensacola',cv()]+s['pensacola',cv()-1]but I'm really trying to understand why what I have doesn't appear to work the way I expect.

Because
(s['pensacola',2003] = sum(s)['pensacola',cv() > cv()-1])
means
(s['pensacola',2003] = sum(s)['pensacola',cv(year) > cv(year)-1])
means
(s['pensacola',2003] = sum(s)['pensacola',2003 > 2003-1])
means
(s['pensacola',2003] = sum(s)['pensacola',2003 > 2002])
means
(s['pensacola',2003] = sum(s)['pensacola',year is any])
s['pensacola',cv()]+s['pensacola',cv()-1]
means
sum(s)['pensacola',year between cv()-1 and cv()]

Trying to Understand the PostSyncCleanup parameter

I've got a problem with running my application on the Australian version of Windows. We have a "test" application built around SQL Server Compact Merge Replication Library (thanks ErikEJ) and that works but our application doesn't.
One of the main differences with our application code is that we do not set the PostSyncCleanup value to anything and the library sets it to 2 per this link:
http blogs.msdn.com/b/sqlblog/archive/2009/04/15/sql-compact-performance-postsynccleanup-to-turn-off-updatestatistics-during-initial-download-of-sql-compact-replication.aspx (put the :// back to get the link)
I'm trying to understand the impact of making that our "production" configuration since we haven't been using it. The description looks harmless enough but I don't really understand what statistics I'm turning off and what the impact
would be and what even the default setting is. Anything that could enlighten me would be appreciated along with a guess as to why that might be causing a problem on the Australian version of Windows would be appreciated.

So we've been running with the default value (0) and have not really had any "problems". I haven't done any testing but I'm ok with faster, like everyone would be, but am also a bit risk averse so want to know what exactly I'm turning off.
I also saw this advice from Rob Tiffany:
Use the appropriate x64, x86 or ARM version of SQL Server Compact 3.5 SP2 to take advantage of the
PostSyncCleanup property of the SqlCeReplication object that can reduce the time it takes to perform an initial synchronization. Set the
PostSyncCleanup property equal to 3 where neither
UpdateStats nor CleanByRetention are performed.
Here: http robtiffany.com/microsoft-sql-server-compact-3-5-sp2-has-arrived/
So, is the best advice to use that parameter and set the value to 3 or 2
I don't really know what I'm losing to "not performing" UpdateStats or CleanByRetention and does making that change need I need to do something else on the server or client to "clear out" or "clean up" something that this is
doing.

Trying to understand the code???

Hi,
I am trying to understand the following bit of code, currently the code puts each catalogue into a different row of the table but i want each catalogue to be put in the next column
(so the catalogues appear across the page on the actual web page). The following code is for the page in question but im not sure how much is relevant so i will paste it all and highlight the section i think is relevant:
<html>
<%-- DECLARATIONS --%>
<%@ page import="se.ibs.ns.cf.*, se.ibs.ccf.*, se.ibs.bap.*, se.ibs.bap.util.*, se.ibs.bap.web.*, java.util.*, se.ibs.ns.icat.*, se.ibs.bap.asw.cf.*, java.lang.*" %>
<% ItemCatalogueBean bean = (ItemCatalogueBean)SessionHelper.getSessionObject("ItemCatalogueBean",session);
   String resourcePath = bean.getResourcePath(null);
   String title = "Product catalogue";
   String languageCode = bean.getLanguageCode();
%>
<%@ include file="FuncHead.jsp" %>
<BODY class="IBSBody" onLoad="loaded = true;">

thank you for your help

You've probably already seen these, but here are a couple of links that may help.
http://help.adobe.com/en_US/FlashPlatform//reference/actionscript/3/operators.html#array_a ccess
http://www.adobe.com/livedocs/flash/9.0/ActionScriptLangRefV3/Array.html
What's basically happening is that the "for" loop goes through each item in the array. Don't be confused by the fact that two of the items in the array are Strings and one is an Integer - variable i being a String has nothing to do with the data type of the elements in the array.
The following code:
private function createLabels():void
     var myArray:Array = ['one', 'two', 3];
     for(var i:String in myArray)
          trace("i = " + i);
          trace(myArray[i]);
gives the following results:
i = 0
one
i = 1
two
i = 2
3
From that we can see that the "for" loop is assigning the index number of each array element, not the actual array element ('one', 'two', or 3) to the variable i. So calling myArray[i] is the same as calling myArray[0] the first time through the loop. This type of "for" loop is just a shorter way of doing the following, which produces exactly the same results:
private function createLabels():void
     var myArray:Array = ['one', 'two', 3];
     for(var i:int = 0; n < myArray.length; i++)
          trace("i = " + i);
          trace(myArray[i]);
Hope that helps.
Cheers!

Trying to understand the basic concept of object oriented programming.

I am trying to understand the basic concept of object oriented programming.
Object - a region of storage that define is defined by both state/behavior.
( An object is the actual thing that behavior affects.)
State - Represented by a set of variables and the values they contain.
(Is the location or movement or action that is the goal that the behavior is trying to accomplish.)
Variables- (What does this mean?)
Value - (What does this mean?)
Behavior - Represented by a set of methods and the logic they implement.
( A set of methods that is built up to tell's the how object to change it's state. )
Methods - A procedure that is executed when an object receives a message.
( A very basic comand.For example the method tells the object to move up, another method tells the method to go left. Thus making the object move up/left that combination is the behavior.)
Class - A template from which the objects are created.
( I am very confused on what classes are.)
- The definitions of the words I obtained from the "Osborne Teach Yourself Java". The () statements are how I interperate the Mechanisms (I do not know if Thats what you call them.) interact with each other. I understand my interpretation may be horribly wrong. I will incredibly appreciate all the support I may get from you.
Thank you

Object oriented programming is a replacement for the older idea of procedural programming (you can research procedural programming in google). As I understand it, in procedural programming, you have a step by step set of function calls to accomplish some task. Each function receives a data structure, manipulates it, and passes it to the next function. The problem with this is that each function preforms some action for the overall task and can't easily be reused by some other task. Its also harder to read the flow of what is happening with raw data structures flying all over the place.
In object oriented programming, an object calls a function of another object and receives back, not a data structure, but another object. Objects contain a data structure that can only be accessed by its functions. An object is not so much a sub component of a bigger task, as it is a service that any other task can use for any purpose. Also, when you pass an object to the caller, the caller can ask questions about the data structure via its functions. The developer doesnt have to know what the previous function did to the data by reading up on any documentation, or having to reverse engineer the code.
I suggest the best way of learning this is to code something like a library object.
A library object contains a collection of book objects
A book object contains a collection of chapter objects
A chapter object contains a collection of paragraph objects
A paragraph object contains a collection of sentence objects
A sentence object contains a collection of word objects.
Add functions to each object to provide a service
Example: A library object should have a:
public void addBook(Book book)
public Book getBook(String title)
public boolean isBookInLibrary(String title)
The key is to add functions to provide a service to anyone who uses your object(s)
For example, what functions (service) should a paragraph object provide?
It shouldn't provide a function that tells how many words there are in a sentence. That function belongs to a sentence object.
Lets say you want to add a new chapter to a book. The task is easy to read
if you write your objects well:
Sentence sentence1=new Sentence("It was a dark and stormy night");
Sentence sentence2=new Sentence("Suddenly, a shot ran out");
Paragraph paragraph=new Paragraph();
paragraph.addSentence(sentence1);
paragraph.addSentence(sentence2);
Paragraphs paragraphs=new Paragraphs();
paragraphs.addParagraph(paragraph);
Library library= new Library();
library.getBook("My Novel").addChapter("Chapter 1",paragraphs).
Now, lets say you want to have a word count for the entire book.
The book should ask each chapter how many words it contains.
Each chapter should ask its paragraphs, each paragraph should ask
its sentences. The total of words should ripple up and be tallied at each
stage until it reaches the book. The book can then report the total.
Only the sentence object actually counts words. The other objects just tallies the counts.
Now, where would you assign a librarian? What object(s) and functions would you provide?
If written well, the project is easily extensible.
