What IDE, Version and other stuff
I am planning to write a package that runs at three places
- on a web site
- on a kiosk at a customer site
- on a PDA (Palm OS to start)
There will be at least two levels of capability (most users probably won't want their PDAs filled up with all the features, I know I wouldn't).
It seemed to me that Java was the programming platform to start with even though I am a C++ programmer (Visual C++) for the last 6 years and am just starting to learn Java.
1. Is Java the best solution?
2. Should I write the PDA software in C++? I have read some of the literature on Java for PDAs and it doesn't really look encouraging. Am I reading the correct articles?
3. Should I write all of it in C++? I think I can get past some or all of the multi-platform issues by using the Abstract Factory pattern (Design Patterns by Gamma, Helm, Johnson, and Vlissides).
In your previous message you said:
I use Jext from www.jext.org which is a fine editor
that is written in Java so it runs anywhere that Java
runs.I downloaded jext from www.jext.org, did the installation to the default place (c:\program files\jext...) and I have a couple of problems with it.
First the editor seems to work just as advertised, but I don't know how to get any use of the thing. I can't seem to figure out:
- how to run a java program after I edit it.
- what the tools "dawn" and "python" are.
Also there is a suggested web site http://www.jext.org/win32Jext.html
that tells how to get .java files to go to jext on a double click. When I tried it I found an error in the jext.bat file. When I double click on my file in c:\dad\java\samples\shop\shop.java I get the message:
C:\Program Files\Jext\bin>start javaw -Xmx32m -classpath "";..\lib\jython.jar;..
\lib\dawn.jar;..\lib\jext.jar org.jext.Jext "C:\DAD\JAVA\SAMPLES\SHOP\SHOP~1.JA
V"
Cannot find file 'javaw' (or one of its components). Check to
ensure the path and filename are correct and that all required
libraries are available.
Any suggestions?

All of a sudden, new tabs have started opening up (in Firefox) advertising games and other stuff. Any idea's of what is going on here?
Try scanning for malware using the removal tools listed near the bottom of the [[Troubleshoot Firefox issues caused by malware]] article.
It might also help if you could copy and paste troubleshooting information into your reply. See [[Use the Troubleshooting Information page to help fix Firefox issues]] for details. -
When logging in to an application I get this message:
You are attempting to access ezLaborManager with the following unsupported browser:
Firefox Mozilla/5.0 (Windows NT 6.1; WOW64; rv:6.0.2) Gecko/20100101 Firefox/6.0.2
ezLaborManager is only supported on current production versions of Internet Explorer and Firefox. "Beta" versions and other browsers are currently not supported.
It is strongly recommended that you use a supported browser to avoid encountering access and display issues.
WHAT VERSION OF FIREFOX SHOULD I USE?Well, you can waste a lot of time and money trying to get your old iron up to speed but the sad fact is, even though it may work with Color, it will most likely end in a less than satisfactory experience all around. You need to determine if your G5 has PCI, PCI-x or PCIe slots and then purchase the appropriate cards.
However, Final Cut Studio 2 is optimized for the Intel processors. You will see users here and there using the newest models G5 with great success but quite honestly, you need a Mac Pro.
Or just purchase the Aja IO/HD which is a firewire 800 interface and the only firewire device that will preview externally Color. -

If I create a new apple id account on my ipod, will I still have all my music, apps, books and other stuff on my ipod that I downloaded and bought with my old account or will I loose everything; will I be able to still do the updates to those apps?
I really need help!I don't think you understood what I wrote. You don't HAVE to pay for everything if you are happy with using the other account for updates, etc. But if you don't want to do that then you will have to buy new copies of everything for the new account. There's only one purchase item per account, but you can redownload an item in the account many times.
The idea is this:
One computer, multiple devices, one Apple ID.
One user, multiple devices, one Apple ID.
The basic idea is that each user has an Apple ID under which he/she can manage multiple devices on a single computer.
Once you step outside of that model you create such problems as not being able to use or update apps purchase under one Apple ID when using a different Apple ID. Or not being able to easily sync one device on more than one computer. -
I have a problem, my wife has an ipad with photos , emails etc etc, she has recently got herself a new iPad Air, has now been using that for two or more months, more photos (new) more emails and other stuff. What she wants to do is get all she wants from ipad 1 to new ipad without finishing up with 2 of everything which happen on previous occasion. I realise that she needs to tidy up ipad 1 first and get rid of thousands of emails etc. I need help.
Thanks kiwihdriderHi yes that works well when the new ipad hasn't been used. Trouble new one has been used for two months or more, has lots photos email etc etc. I am worried that these will go. When we did iPhone thru same process finished up with two of most things pics and emails. The emails alone were over 2 thousand and wife reluctant to delete them all. I would and just sort pics. Any other ideas

My iTunes only show: iTunes U and category , no music and books and other stuffs. Is it because of my Chinese ID?
You can only purchase content from the store where your credit card is registered - and that credit card must be registered to a valid address in that country. I am afraid that you are restricted in what you can legally purchase from Apple.
Sometimes the restiction of content has to do with licensing rights and sometimes governments will restrict the content that Apple is allowed to sell in their countries. -
I know that iCloud backs-up apps and other stuff to your phone incase you want restore from a back-up if you start a New iPhone. My question is if I start a new iPhone (not use the restore from back-up option) and redownload apps like (Games, Instagram), would my pics show up on Instagram and would my Games show it was saved and the acccomplisments will remain from the last place I left out.

After this you will have the option to restore your contacts and other settins. The question is will it restore my first phones info? I am hesitant to delete anything lol.
No. If you made your backup to iCloud, iTunes will not restore from an iCloud backup. See:

My friend put cydia on my ipod and other stuff from it like something who slide your apps differently. How can I remove the both, I really want, plz help ...?
They hacked it and may have caused damage to your device. Jailbreaking also voids your warranty and support from Apple. To restore to a clean state, restore in Recovery Mode: http://support.apple.com/kb/HT1808

I'd like to get iWork on both my ipad 2 and iphone 4 mainly for traveling purposes... Right now I lent my iPad to my dad whose in somewhere else now so I don't have access to the iPad. So, I was wondering if right now I buy iWork onto my iPhone, and then when the iPad comes home, can I install that same iWork I bought through my apple acout and not have to pay for another version, and the iPad iWork can go full screen beautifully and not ugly?
iWork is universal, so it will work full-res on the iPad. This is true for any app which has the plus sign symbol (in the App Store in iTunes it will say "This app is designed for iPhone and iPad".

I have been running 5.0 great for a while now, but today I tried downloading and running FF 3.6. As it was opening it stopped responding, but then I tried to force quit but then it worked and loaded up the pages I had open on 5.0 when I closed it.
I then closed the 3.6 version and ran the 5.0. I noticed a few things were gone or different...
~Several add-ons/extensions and toolbars were gone. Some of them were: Adblock Plus, Read it Later (and all its saved pages), Stumble Upon toolbar.... and more I am not sure of...
~Some of the saved sessions in my Session Manager add-on were gone.
~FF 5 seems to not be asking if I want to save my pages whenever I quit.
~The settings for how my tabs appeared has changed also... Like the color of text and where a new tab goes when I click on a link (to the right of the current tab or all the way to the right)... I am not sure if this is because of an associated add-on/extension being deleted.
UPDATE: I checked my profile folder and all of the extensions' data is all still there but FF5 is just not reading it correctly. (like adblock plus... I see the folder for it but FF5 doesn't have it on the add-on manager page when I run FF5) (The stumble upon toolbar folder is also in my profile folder but is not showing up in View->Toolbars when I actually run FF5)
Any help would be extremely appreciated.
Thanks!Thanks but I don't think this will help. Like I said, all of my add-ons were working fine and compatible until after running a previous version of FF. I am sure they are still compatible, but they are not working at all.
I even checked my profile folder and all of the extensions' data is all still there but FF5 is just not reading it correctly. (like adblock plus... I see the folder for it but FF5 doesn't have it on the add-on manager page when I run FF5) -
Using 'what size' what in Library (and other folders) to delete?
In Library I notice a lot of 'packages' and 'receipts' folders/files - 'pkg' files - can they be dumped?
There seems to be similar files in 'previous system' - can they be dumped too?
What is the 'private/var' folder? - can anything be dumped from this?
Any other tips for deleting redundant files and folders - I've already got rid of the other languages related stuff.
Many thanks

Empty the trash!
Open up your application folder & go through all your apps. Trash all the apps you no longer want and/or use.
An easier way to do this is to open the Application folder in list view & press the Command+j keys.
In the the dialog that appears, click the "This Window Only" button & the "Calculate All Sizes" check box.
Wait a bit until your file & folder sizes have all been calculated, then click the "Size" column to sort your apps from the fattest to the most anorexic.
Get rid of all your photo files you don't want and/or need. Same goes for those pics off the websites you downloaded (gifs, jpegs, etc.).
Get rid of all your music files you no longer listen too. Especially, if you already have the actual CD/DVDs or you can later redownload from a website.
Use Spotlight to make sure you got rid of everything. You can even trash directly from Spotlight!
Drag what you don't want and/or need to the trash. Better yet, download this neat little shareware app demo called AppZapper. It basically does all the work for you by not only trashing the apps but the apps preference files, caches & all its associated files.
Another software that does the above is AppDelete. Best of all this software is free!
Burn what you want and/or need onto CDs or DVDs.
Not everyone has the luxury of purchasing an external HD and/or Mobile accounts to store their "stuff.”
You can check with your ISP to see if they offer free storage space. Most if not all do now-a-days.
There are thousands if not millions of free storage facilities on the web also. Use your favorite search engine to search them out as they come in different storage sizes to fit your needs & wants.
Check for duplicate fonts.
Applications>Font Book
Select “All Fonts”
If you see any “black dots” next to any fonts this mean you have duplicates and/or multiple versions of these fonts.
To clean this up, select a “black dotted” font or the Apple + click to select multiple dotted fonts;
Edit>Resolve>Duplicates.
What the above does is turns off the duplicates & multiple version fonts. Not delete them.
More than likely the “extras” were installed by other programs and/or other users.
Clear out font caches
Use FontNuke. It does all the work for you. And, best of all it’s FREE.
Printer Drivers
Get rid of all the printer drivers you don’t need & use except the ones for your current printer(s)/scanner(s).
HD>Library>Printers Folder
If you accidentely threw something out that you needed for your printer/scanner it can be easily obtained from the manufacturer’s website and/or from the CD that came w/the printer/scanner.
Garage Band
Has about 1GB of loops stored. Get rid of some some them. You surely don’t use, like and/or need them all.
HD>Library>Audio/Apple Loops>Apple>Apple Loops For GarageBand
Or just get rid of the Garage Band app altogether if you don’t use it.
Get rid of extra languages
Strip your computer down to your “native” tongue.
You can do this with a FREE utility called Monolingual. Another app that apparently does all the work for you. I’ve never used it. However, a lot of users here swear by & recommend it highly.
However, there is a warning for *native English speakers*. Make sure you keep BOTH English and English (United States).
