NEED HELP - Skype Phone icons for my site - one fo...

I need help please
I have a website with 1000+ members (1000+ phone numbers). I need members to call each other once we give them approval to contact via phone. However, I don't want them to see each other's number (also, it should show while dialing) but just click on logo and the other site phone rings (system will search database and call number assosiated to a profile.)
I have my PHP developers but they are not sure how to even start and out of ideas. And even if we do it on our website, will it destroy our site's performance/bandwidth...etc

Hi, Tamer732,

Not exactly iweb - need help with a graphic for my site

This doesn't fit anywhere so dumping it here. I drew by hand a graphic I want to use with iweb to put on my site as my site's logo. Main problem is that getting the background transparent isn't working well as when it was scanned the scanner didn't back the background "pure" white. I have tried adjusting the whitepoint and setting the color depth down, but still no good. I don't know a ton about graphic program use. I have an older copy of graphic converter that came on this powerbook when i got it. I would be fine having the graphic loose the marker look and have solid fill colors - just I am not good enough with computer drawing tools to do it on the computer! So I either need to get a volunteer to help me out, or some help with some detailed instructions to get this to work out... (also I am broke so no cost/shareware is only option here)
many thanks!!!!
I can get you a scanned jpg of the pic if needed.

THANK YOU/___sbsstatic___/migration-images/migration-img-not-avail.png so the tolerance makes it not care so much about the gradations in color? what else is tolerence good for?
I have a cleaner copy now after someone suggested GIMP, so played with it last night - though couldn't figure out transparency - that was clear on converter- just not cooperative till these wonderful directions.
So now I know how to do it without messing with the pic, and with messing with it - both good lessons and got a bit brighter color out of the deal.
many thanks for the straightforward and clear directions, they worked perfectly/___sbsstatic___/migration-images/migration-img-not-avail.png extra strars for you/___sbsstatic___/migration-images/migration-img-not-avail.png

Here's how to use your own custom Webclip icons for the sites you visit.

This method is pretty much 95% taken from this URL: http://allinthehead.com/retro/319/how-to-set-an-apple-touch-icon-for-any-site , so credit where credit is due. The instructions are a bit hard to understand though, so I'll try to make it easier for everyone.
Fortunately, this works for both Macs and PCs.
INSTRUCTIONS:
Requirements:
- iPhone on 1.1.3 and any version of iTunes that can sync to iPhone
- Adobe Photoshop or any other image editing program that can crop, alter image size, and save .png image files. (Recommended 24-bit .pngs as they are higher quality)
- Apple Safari ( http://www.apple.com/safari/, and yes, you need it.)
- A website or ftp where you can upload images and directly link to them, like Google Pages.
Warning:
- This requires you to sync your Safari bookmarks to your iPhone. You will probably lose all of your iPhone's bookmarks if you don't already sync your Safari bookmarks with your iPhone. Only proceed if you do not mind losing your iPhone's current bookmarks and do not mind re-entering them after the bookmark sync. NOTE: The bookmark sync DOES NOT get rid of your current Webclips though, so don't worry about those.
Easy Steps:
1) First, make sure that you are following these instructions in the Apple Safari web browser.
2) Find an image you wish to make into a Webclip icon. (ex: I prefer to use movies.yahoo.com to look at movie showtimes, so I found an image of a movie reel from Google Image Search and decided to use that.)
3) Open the image with your preferred image editor and crop your desired image into a perfect square. Resize that picture down to 57x57 pixels. Save as a 24-bit .png file. Upload the icon to your webpage or ftp. (ex: I ended up with this icon of a movie reel: http://ctolpin.googlepages.com/appleicon01.png )
4) Select and copy the javascript code in this .txt file: http://ctolpin.googlepages.com/webclipcode.txt
5) Go to Bookmarks and select "Add Bookmark..."
6) Type in "Webclip Icon URL"
7) Go to Bookmarks again and select "Show all Bookmarks."
8) Right-click your new "Webclip Icon URL" bookmark and select "Edit Address"
9) Paste your clipboard's contents into the field.
10) Plug your iPhone into the computer if it's not connected already.
11) In iTunes, select your iPhone from the right column. Select the Info tab. Scroll down to "Web Browser" and check "Sync bookmarks with: Safari" (obviously, make sure Safari is selected from the dropdown menu).
12) Once your iPhone is synced, use your iPhone to navigate to your intended website target to make into a Webclip. Remember that Webclips save where you zoom in as well! (ex: For me, it was movies.yahoo.com and then entering in my zip code.)
13) Once you've loaded your target website, open up the bookmarks in iPhone's Safari, select Bookmarks Bar, then select Webclip Icon URL.
14) Type in the address of your uploaded icon. (ex: In my case, it is http://ctolpin.googlepages.com/appleicon01.png)
15) iPhone's Safari will seem like it didn't do anything. However, add that webpage now to your home screen as a Webclip. Magic.
Additional note:
It is easiest to make a bunch of icons at first and to upload them. However, once that "Webclip Icon URL" bookmark is in your iPhone, there is no need to go back and do any of the computer Safari steps again
My front page icons in order (Sorry Stocks, it's the second page for you!):
Google, Wikipedia, Definr, Showtimes

3 Go to the port forwarding section and copy down the Applied Rules.
Example:
Network Computer/Device: 192.168.1.100:63145
Application & Ports Forward: Application UDP Any -> 6347
Note: There may be up to three entries for each one of your Set Top Boxes.G
Your display obviously is not like mine as mine does not dosplay the port associated with the ip address
whatever, the STB's start at 192.168.1.100 and icement by 1 for each
the port addr's will be 63145 alo incrementing by 1
there is 1 entry for each in my pf list
however each ip addr also has a port entry starting at 35000 also incrementing by 1 for each ip addr
For some unknow reason these are duplicated e.g I appear to have 11 entries exaactly the same for each stb and as the fios services rules have no action switc there is nowhere to delete the extraneous garbage.
Why do you clone the mac addr??

Lost Phone Icon for iPhone 4

I lost my phone icon for my iPhone 4. I tried a reset - holding the sleep button and bottom button. It rebooted, but the icon is still gone. Everything else is fine. What do I need to do to get the phone icon back?

Did you possibly accidentally move the phone icon into one of your folders? Can you still dial out using one of your contacts? Check these things before restoring a backup from your itunes (assuming you made backups).

-Business Area
-Begin and End Date.
Other fields from IT0017 need to be derived from Position and update in IT0017.
Please guide me how I can address this. I do not want to go for dynamic action, as it is not getting evoked during background jobs.
I am new to BADI development and will appreciate step by step instructions.
Thanks

Hi,
     follow the below steps to achive
Steps:
1.     Execute Business Add-In(BADI) transaction SE18
2.     Enter BADI name i.e. HRPAD00INFTY and press the display
        button
3.     Select menu option Implementation->Create
4.     Give implementation a name such as Z_HRPAD00INFTY
5.      You can now make any changes you require to the BADI within this
        implementation, for example choose the Interface tab there are 3 methods avialble
6.     Double click on the method you want to change, you can now enter
        any code you require.
7.      Please note to find out what import and export parameters a
        method has got return the original BADI definition
        (i.e. HRPAD00INFTY) and double click on the method name
        for example within HRPAD00INFTY contract is a method
8.      When changes have been made activate the implementation

Need help with calculator project for an assignment...

Hi all, I please need help with my calculator project that I have to do for an assignment.
Here is the project's specifications that I need to do"
"""Create a console calculator applicaion that:
* Takes one command line argument: your name and surname. When the
program starts, display the date and time with a welcome message for the
user.
* Display all the available options to the user. Your calculator must include
the arithmetic operations as well as at least five scientific operations of the
Math class.
-Your program must also have the ability to round a number and
truncate it.
-When you multiply by 2, you should not use the '*' operator to perform the
operation.
-Your program must also be able to reverse the sign of a number.
* Include sufficient error checking in your program to ensure that the user
only enters valid input. Make use of the String; Character, and other
wrapper classes to help you.
* Your program must be able to do conversions between decimal, octal and
hex numbers.
* Make use of a menu. You should give the user the option to end the
program when entering a certain option.
* When the program exits, display a message for the user, stating the
current time, and calculate and display how long the user used your
program.
* Make use of helper classes where possible.
* Use the SDK to run your program."""
When the program starts, it asks the user for his/her name and surname. I got the program to ask the user again and again for his/her name and surname
when he/she doesn't insert anything or just press 'enter', but if the user enters a number for the name and surname part, the program continues.
Now my question is this: How can I restrict the user to only enter 'letters' (and spaces of course) but allow NO numbers for his/her surname??

What you could do is checking the input string for numbers. If it contains numbers, just reprompt for the Name.
AND you might want to ask yourself why the heck a calculator needs to know the users Name.

Need help choosing optimal hardware for a laptop that will run AE CS5

BACKGROUND INFO (Questions listed below)
I need some help figuring out the best hardware configuration for a new laptop. I’m a student at a design school and I will be using the laptop to mainly run After Effects and to a lesser extent Photoshop and Illustrator. I don’t need to worry about 3D rendering software or Premier Pro. I am primarily interested in getting the best performance during editing. I am not looking for the best performance for final output. I would prefer to sacrifice final output times for better editing/interface performance.
I will be working with standard definition content and perhaps HD up to 720p on occasion. I do not need to operate in resolutions higher than 720p. My projects are generally animation and use many sources and many layers.
I’ve been reading up on optimal hardware configurations for CS5 but my understanding is still a little foggy and I would like to use this thread to figure out how to build the best machine for my budget. The budget is about $1400 to $1600 CANADIAN after tax.
I DON’T need help finding the laptop. I will search for it on my own. I just need to understand the best hardware to purchase within my budget.
I realize that it is probably impossible to buy the laptop I want with the hardware configuration I need “off the shelf”. Instead I will be looking for a good base model (~$900-$1100) and I will purchase the necessary hardware upgrades separately. I will not be purchasing a Mac.
Right now I’m thinking of a machine built something like this:
- 15”-16” screen (17” models are too big/heavy)
- Mid to high end i5 processor OR entry level i7 quad core
- 8GB RAM (I would go to 12GB, but it’s hard to find a 15”-16” laptop with 3 memory slots)
- SSD to replace HDD (However, if possible, I would like a laptop with dual HDD support or swap the optical drive for another HDD. If I had access to 2 drives, I would have and HDD/SSD combo).
- Medium/high end NVIDIA GPU to take advantage of OpenGL while editing.
QUESTIONS
1) Does the “Render Multiple Frames Simultaneously” option enhance general editing performance (applying filters, scrubbing through the timeline, reverting history states)? Or does it ONLY help speed up RAM previews and final output? Does it reduce the length of RAM previews?
1b) Is this option even necessary to enable on 64bit systems? (As far as I understand it was used to solve a problem where 32bit systems/software would only recognize 4GB of RAM per instance of AE).
1c) If I turn this option on to help with RAM previews, would I be hindering general editing performance in any way? Or does this option have basically zero drawbacks?
2) How come “Actual CPUs that will be used” will read 0 even if the sum total of RAM assigned to the CPUs plus the RAM reserved for other applications is less than the total available system RAM (on a 64bit system)? For example, I currently have 4GB RAM and 2 installed CPUs. I have 1.5GB reserved for other programs and when I set 0.75GB per CPU both CPUs are used. However when I set 1GB per CPU then 0 CPUs are used, even though the total RAM adds up to only 3.5GB.
CPU
3.) Considering the fact that I am more concerned with smooth performance while editing rather than final output speeds, would it be better to get a dual core i5 clocked around 2.5 or a quad core i7 clocked around 1.8?
4.) What is the difference between an i3 and an i5 processor even if they are clocked at the same speed? How does an i5 460M compare on the grand scheme of things?
RAM
6.) Should the quantity of RAM that I get (8GB vs 12GB) be based on the number of cores in my CPU? If so, how should I be calculating optimal RAM based on # of cores. Should I also be counting threads, or just actual physical cores?
STORAGE/SWAP
7.) Should I replace the HDD with an SSD? I'm looking for snappy interface performance while editing. I would think that if the RAM fills up it would be best to have the SSD for scratch/cache.
8.) What performance benchmarks are most important when considering an SSD for After Effects? (4k writes? IOs per second? Max read/write?)
9.) I can afford the OCZ Vertex2 120GB SSD. Would this be a good choice if an SSD is recommended?
10.) Would it be better to have 8GB of RAM and an SSD, or 12GB of RAM and an HDD? Explain why.
GPU
10.) After Effects utilizes OpenGL to enhance editing performance. I will not really be using Premier Pro, so catering to the CUDA Mercury Engine is not a concern. Do high end gaming cards provide significant gains in OpenGL performance? Or do OpenGL performance gains taper off around the mid-range GPUs? (i.e. can you justify buying a high end GTX 260M graphics card for enhanced editing performance versus an "entry level" dedicated card like the 310M?)
11.) What hardware specs are most important when considering a GPU for editing performance in AE? (Memory size? # of Pixel shaders? Core speed? Shader speed?)
Thanks so much for any answers you can offer to these questions.

Please make sure that you've read through this page and what it points to.
> 1) Does the “Render Multiple Frames Simultaneously” option
enhance general editing performance (applying filters, scrubbing through
the timeline, reverting history states)? Or does it ONLY help speed up
RAM previews and final output? Does it reduce the length of RAM
previews?
It only increases rendering speed for RAM previews and rendering for final output. In After Effects CS5, it doesn't decrease the length of RAM previews. (In CS4, it does.)
1b) Is this option even necessary to enable on 64bit
systems? (As far as I understand it was used to solve a problem where
32bit systems/software would only recognize 4GB of RAM per instance of
AE).
You misunderstood. Yes, it's still relevant on 64-bit computers. Moreso, in a way. (I'd rather not spend my entire Sunday writing out detailed answers to satisfy idle curiosity, so I'm not going to give all the technical detail to that answer.)
> 1c) If I turn this option on to help with RAM previews,
would I be hindering general editing performance in any way? Or does
this option have basically zero drawbacks?
It takes a small but nonzero time for the background processes to start up when they need to be used and shut down when they're done. And as they sit waiting, they take up a little bit of memory. So, it's not exactly correct to say that there are no downsides to leaving it on. But it's close. I leave it on.
> 2) How come “Actual CPUs that will be used” will read 0 even
if the sum total of RAM assigned to the CPUs plus the RAM reserved for
other applications is less than the total available system RAM (on a
64bit system)? For example, I currently have 4GB RAM and 2 installed
CPUs. I have 1.5GB reserved for other programs and when I set 0.75GB per
CPU both CPUs are used. However when I set 1GB per CPU then 0 CPUs are
used, even though the total RAM adds up to only 3.5GB.
4GB - 1.5GB for other software leaves 2.5 GB for After Effects.
If you have 1GB assigned per background CPU, then the foreground takes 1.2x that = 1.2GB. That leaves 1.3GB for background processes, which is enough for one background process. There's no point in starting only one background process to do rendering, so it doesn't bother. (Note: When background processes are rendering, the foreground process isn't rendering.)
> 3.) Considering the fact that I am more concerned with
smooth performance while editing rather than final output speeds, would
it be better to get a dual core i5 clocked around 2.5 or a quad core i7
clocked around 1.8?
Get the quad-core. That gives you a greater total number of cycles. And After Effects works very well with mutliple processors, even beyond Render Multiple Frames Simultaneously multiprocessing. An entirely unrelated sort of multiprocessing (multithreading) spreads work out to multiple processors.
> 6.) Should the quantity of RAM that I get (8GB vs 12GB) be based on the number of cores in my CPU? If
so, how should I be calculating optimal RAM based on # of cores. Should
I also be counting threads, or just actual physical cores?
The optimum amount is the amount that you can cram into the computer. I'm not kidding. Spend your budget on RAM until you have 4GB installed per processor (and I'm counting the virtual processors due to hyperthreading). If you have a quad-core, that's 8 CPUs with hyperthreading, so the optimum amount of RAM installed is 32GB. You can work with less, but you did ask about optimum. For HD work (i.e., 1920 pixels across), you're OK with more like 3GB installed per CPU. That's what I have at home: 24GB in a quad-core. You're going to assign 2/3 or so of the RAM to After Effects, so 3GB installed per CPU is 2GB per core for HD work in After Effects.
> 10.) Would it be better to have 8GB of RAM and an SSD, or 12GB of RAM and an HDD? Explain why.
12GB of RAM. Because After Effects likes RAM. (If you're thinking of deliberatly using virtual memory to swap memory to the hard disk, don't. That's a performance killer.)
> 10.) After Effects utilizes OpenGL to enhance editing performance.
Not really. If you're on a limited budget, don't even think about the GPU until you've already got the most RAM, the fastest CPUs, the largest number of CPUs, two fast hard disks, and a couple of good monitors. Then, and only then, should you even consider getting soemthing beyond a non-stock graphics card. Yes, OpenGL can be used to accelerate some things, but that's only for the low-fidelity preview renderer. (Pardon the bluntness, but I want to make sure that you heed this.)

Need help in shutdown primary for maintaince (new to oracle dba)

Hi,
BANNER

PL/SQL Release 9.2.0.4.0 - Production
CORE 9.2.0.3.0 Production
TNS for Linux: Version 9.2.0.4.0 - Production
NLSRTL Version 9.2.0.4.0 - Production
actually we have primary database server and the physical standby server with protection mode is maxperformance and for maintaince we need to shutdown primary server so what are the steps i need to follow since my primary database is configured with DATAGAURD and i would like to follow the folllowing steps please advice me:
to shutdown standby server:
from primary server connecting to dgmgrl
dgmgrl>DISABLE SITE standby_site1;
then connecting to standby server
sql>alter database recover managed standby database cancel;
sql>shu immediate;
and finnaly connecting to primary server
sql>shu immediate
is it right since i am new to datagaurd concept need help.
Regards
Prakash

You can do so, but you would shutdown the whole standby environment. But normally standby is used to have no or only short downtime. So a switchover to the standby DB is performed (after this standby is now running as primary), maintenance is done on the primary and then at the end another switchover back from the 'new' primary to the 'old' primary.

You are very welcome.
For others:
1. There is no need to uninstall first. It's wasted time and a wasted step that is NOT required.
2. It is important to inform people that if they delete their Skype folder, that they will be deleting ALL their Skype history:
For others:
You do not need to uninstall, or delete anything, if you have this issue, simply install over, what you have, with this:
At the moment the quickest method to fix this is to install the beta version from here: http://skype.com/go/getskype-beta
