Games/apps to help me learn how to scroll, click, etc?
I'm a long time PC user but work has switched to MacBook Pros for everyone. I use a lot of keyboard short cuts and other things that either don't work or cause problems. I'm struggling to remember when I click with two fingers vs. swiping, how far apart my fingers should be, and so on. I know it's supposed to be intuitive but for me it's just frustrating. More often than not if I need to get something done, I return to my ancient PC.
Is there any game or training software that will help me learn all the keyboard shortcuts and correct finger motions for my new MacBook Pro? All IT will tell me is 'use it to learn it' which doesn't help when I can't get through a simple web page or document.
I've helped some users to learn how to become more proficient with the tap/swipe interface, and you know it takes some getting used to.
The IT people who tell you "use it and learn in" are exactly right. Otherwise, you spend your time referrng to lists of procedures and commands, and learning comes even more slowly.
Cheat Sheet http://www.cheatsheetapp.com/CheatSheet/ is a free application that will remind you of the most common hints that are available to you, given your system; tap on the action, and it will automatically launch the command.
Apple has video and textual tutorials http://www.apple.com/findouthow/mac/ to jump-start your learning.
Concentrate on the things you like to do (like web browsing or entering text) and build your competency bit by bit. For beginners, it's best to get help from a fellow user, if you can.
Among the most important information: Learn it automatically, like a language, as if it's second nature.

Need help for learning how to develop interfaces for Oracle R12 EBS
Hi all,
I need to learn how to create interfaces in PL/SQL for Oracle R12 EBS Financials. I cannot find a good starting point for the documentation and examples to help me get started in this area. Would appreciate tips
for this area.Hi,
What kind of interfaces you are planning to develop?
Oracle already provides list of APIs that can be used (in R12, it is responsibility).
Oracle Integration Repository Documentation Resources Release 12 [ID 396116.1]
Oracle Integration Repository
http://irep.oracle.com/index.html
If those APIs do not satisfy your requirements, you can refer to "Oracle Applications Developer" guide as well as SQL-PL/SQL guides.
Applications Releases 11i and 12

My wife and I are trying to learn how to use Air Drop. The "tutorial" showed us where it is. It came up. I saw hers (Mac). She saw mine (Mac). But where to go after that is, apparently, in the cloud somewhere. The description says we can share files...which is nice...but nothing tells us HOW to share those files.
Thanks for your help out there...
Dennis1. Open a new Finder window or use one that's already open
2. Click on Airdrop, press Shift+Command+R, or find "Airdrop" in the "Go" menu
3. Drag your file to the icon of the person you want to send the file to (if you have mountain lion, you can use the share button).
4. The other person has to click "save"
5. The file will send and appear in the receiver's downloads folder
In Mountain Lion, a new feature was added: the share button. It's a button with a picture of a box and an arrow jumping out of it. Click on it and the third (and last) option is "Airdrop" and clicking on it will allow you to send files over Airdrop without opening it in Finder. -
Java game app - need help on creating more adversaries
HI all, this app is a simple game where the objective is to avoid incoming balls (adversaries) however at present I can only figure out how to get one ball on screen at a time. What I'd really like is, when a player hits 100 points, a second ball is spawned (thus making the game harder) I would like the same to occur at 200 points (3 balls), 400 pts (4 balls) and so forth. I am sure there is a simple way of doing this. what I have tried is creatin new instances of Ball, but to no avail.any help would be greatly appreciated.
cheers

}On an off note, there are some things you can do here to make multiple balls much easier to create, track, and manage. One thing is that your Ball class should have a record of all properties that are in anyway related to a Ball object.
I notice that you handle Ball color within your paint method. Your Ball class should have a Color field so every instance of Ball is aware of its color, and then your paint method can grab the necessary color from the object itself that it is painting. You wont need to keep a color index and color collection.
Secondly, to track multiple balls you will need a collection object that holds multiple Ball objects. Everything in your paint method right now is looking at one instance of Ball because there is only one reference of Ball. Instead of doing it this way you can keep a number of Ball objects in an ArrayList lets say, and then create a for loop that iterates through element of the List, and performs operations on that ball, like grabbing its color, filling the shape, calling the Ball's move method. -
Help me learn how to back up and set up a recovery on new MacBook please?
Please bear with me if I come across not knowing anything about this topic....but that's why i'm asking for help.
mentioned before that my brother set up my PC laptop for me years ago. And a friend set up my Western Digital External Hard Drive (My Book Essential Edition - i got it super cheap after rebates) and I know he downloaded Syncback from 2Brightsparks since the WD didn't come with software.
My new Macbook is charging up. I want to know if I should do a backup and recovery? Basically I want to prepare for in case I totally eff up my new Mac and have restore from scratch. I am so confused when I read forums and google stuff. I know it came with the Mac OS X, but what happens to some of the preinstalled software....will it come back up if I use the Mac OS cds? Also, I've read that some say I can backup on CD/DVD but they won't be bootable but if I use external HD it's bootable - what the heck does this all mean?
Will I have to download a software to use with the WD HD or will the preinstalled Time Machine work? (Step by Step directions on how to make a bootable restore and back up would be greatly appreciated)
and when I add other software, can I back up the computer so that if I ever have to do a system restore I can still get those software back on my Mac without having to go get the software disc or pay online again for the download?
thanks a bunch!Hey Knotty,
If you are close to an Apple Store, you would do yourself a world of good if you purchased One-to-One Membership. The Creatives at the Apple Store can teach you how to do all of this and so much more, for a full year.
Time Machine is an automatic backup system that is pre-installed on your Mac. It is very easy to use. Since you already have the WD, you could use that for this purpose. There is no other software you would have to purchase. If there are files and such on your WD, I would first back those up to some other media, DVD or CD, then let Time Machine reformat it and use it. It will not use the same format as your old PC, which is why you will need to backup those files you need off of it.
Good Luck.

It's impossible to make certain modification to the content on your iPod if it is not connected to a computer. In fact, just about the only thing you can do from the iPod is rate your music.
If you want complete control, just tell the iPod to manage music manually and you can move things in and delete them as you please.
The reason the iPod works like this is pretty simple, Apple figures that allowing the user to delete music from the iPod all willy-nilly would make the iPod more complex, and therefore more confusing.
But honestly, do you need to delete the podcasts from your iPod RIGHT AFTER you've listened to them? What's the deal with the urgent need to make more space? Unless you're doing transfers from a camera (and I seriously doubt you are) you can just delete them the next time you plug the iPod into your computer. -

HELP-40GB i-pod with scrolling click wheel
ok first of all, i got this new computer. I dowloaded itunes onto it. I want to plug in my i-pod into my new comp but im afraid that all my songs will be deleted. I have all my songs on my other computer, but the other computer isnt working. I also need to plug it into the new comp because a little folder with the ! comes up every once and a while. Also, my i-pod begins to play a song then it stops and it goes to the next song, this is related with the menu icon and the !. Now all of a sudden i press the MENU button and the apple logo pops up then it just turns back off. WHAT DO I DO? i want to keep all my songs, but at the same time im afraid that if i plug it into the new comp all my songs will disappear. Also why is my i-pod just shutting off when i turn it on?
I-pod with the scrolling click wheel Windows XPThe first thing that anyone is going to suggest to you in respect of the folder and ! error is to reset your iPod and/or restore it. Restoring the iPod will erase anything that's stored on it and return it to factory settings. You may not have any choice but to do this.

Learn how to use Powershell with AD, Exchange and Excel
Hi.
I want to learn how to script in Powershell to make my life easier at work.
Now, I'm creating Distribution Lists with cmdlets, and other simple moves, but I'd like understand and use scripts with Excel to make it easier in AD and Exchange.
Can anyone help me find out where I can learn Powershell with those tools? I've searched google and youtube, and bought books, but I'd like to learn especially about AD and Exchange through Excel.
I also have another question, I'm trying to collect the telephonenumbers in one OU in AD, and found this cmdlet:
Get-AdUser -Filter * -Properties OfficePhone | FT OfficePhone,UserPrincipalName
I lined ut the OU path before -Filter, and used * -Properties Telephones Mobile to find the phonenumber in Properties-Telephones-Mobile in Active Directory. But I'm obviously doing something wrong.
Could anyone please help me?Hi Wezcomp,
first of all, you can use Get-Help to learn how to use Cmdlets, by asking them what it is they do:
Get-Help Get-ADUser -Detailed
By Adding the -Detailed Parameter, it will explain each Parameter of Get-ADUser and what it does. Then it will show you examples on how to use the cmdlet. Very useful tool,
Get-Help, learning to use it fully ought to be your first step, as this unlocks your access all other aspects of PowerShell. With that tool in hand, you could theoretically do the rest fully autodidactically (would be frustrating though, since you'd
like to be able to do something specific right now. Don't worry, we'll gladly help anyone truly trying to learn.).
There are lots of tutorials out there that can be useful in a general way (I added my own here). But regarding Excel:
As Fausto said, CSVs are the simple most way to do this. I'd advice against delving too deep into Excel manipulation right now (lots of frustration, little immediate rewards), Csv is your friend. Notable Commands:
Import-Csv
Export-Csv
For example, if you want to create a csv list with user data in it, using your previous example, you can do this:
Get-ADUser -Filter "*" -Properties OfficePhone | Export-Csv "C:\example\users.csv" -NoTypeInformation
By the way: FT (Format-Table) is a treacherous command: It displays objects to the console, but it is a dead end where data is concerned! Only use it when you want to check something quick on the console (like whether you got the right data), before
continuing on without using a Format command.
Cheers,
Fred

Learning how to use Layout Managers
The code that is included in this post is public code from the SUN tutorials. I am trying to learn how to use the layouts and add individual programs that were created to each component in the layouts.
This is what I am exploring:
I want to have a tabbed layout like the example TabbedPaneDemo located at http://java.sun.com/docs/books/tutorial/uiswing/examples/components/index.html#TabbedPaneDemo. Below is the code.
In one of the tabs, I want to place a button and report in it. When the button is clicked, I want the report refreshed. Eventually I will be populating an array with data. The report I want to use the example SimpleTableDemo located at http://java.sun.com/docs/books/tutorial/uiswing/examples/components/SimpleTableDemoProject/src/components/SimpleTableDemo.java. Below is the code.
From what I have learned, you can place a container inside a container. So I should be able to place the SimpleTableDemo inside the tab 4 of the TabbedPaneDemo.
If this is indeed correct, then how do I put these two things together? I am getting a little lost in all the code.
Any assistance in helping me learn how to create and use layout managers would be appreciated.

there are several more lines but as I was typing them out I thought that maybe the code is not written to run it in the command window. The errors seem to be around the ClassLoader. Is that correct?
