Shadowing in the classroom

I am attempting to setup a classroom object in SGD 4.2. When I specify the "winclass.exp" for the login script I get the following error:
ErrEvalFileFailed
Script 1347 exited with code 44 and signal 0
When I look at the execpe error log, it gives me the following information.
2006/02/20 11:14:58.071 (pid 1347) execpe/script #0

This worked fine in Tarantella 3.42. Any ideas on how to fix this for SGD 4.2?

I figured it out. In case you installed SSGD on Linux, there's a bug in the tarantella start script. Change following lines in /opt/tarantella/bin/tarantella:
339 if [ $pkgres = 0 ]; then
340 TTABASEINSTDIR=`pkgparam $pkginst INSTDIR 2>/dev/null`
341 pkgres=$?
342 fi
343 if [ $pkgres = 0 ]; then
344 TTABASEDATADIR=`pkgparam $pkginst DATADIR 2>/dev/null`
345 pkgres=$?
346 fi
to:
TTABASEDATADIR=/opt/tarantella/var
TTABASEINSTDIR=/opt/tarantella
the above commands in line 340 and 344 "pkgparam" are working on solaris only!

Is there a way of connecting the ipad to the smart board in the classroom, so that the smartboard is the control, and the ipad is displaying what is on the smartboard? This is to help a visually impaired child see what is on the smartboard.,

Is there a way of connecting the ipad to the smart board in the classroom, so that the smartboard is the control, and the ipad is displaying what is on the smartboard? This is to help a visually impaired child see what is on the smartboard.

Absolutely!
Install Splashtop2 on the PC and enable it to be controlled or ran from iPad or Reflection to simply allow iPad to serve as PC unwired monitor. With Splashtop and an Apple TV connected, you use the smartboard as usual, yet the PC and iPad can see the same content. The impaired child can even interact with the Smart Board via the iPad as if he were writing directly on the big screen. Erasing functions can be done by touching the Smart Board manual controls. Several variables are in play that cause this lack of functionality:
    Apple won't permit PC software that infringes its proprietary apps.
    Smart Board companies refuse to develop iPad apps because they feel threatened and are being replaced by iPads
    School districts think Apple TV is meant for copyright infringement and could expose them to safe harbor lawsuits
    Network administrators make it impossible to login Apple TVs because they don't want the streaming occurring
    Classrooms are not able to keep up with the technology of using the iPad
    Clicker companies refuse to play with iPad because they see it as a potential threat to their core business clients
    Apple is not working as hard as it could to exploit its capabilities in education, thus losing money in iPad sales
The bottom line is that we educators and technology developers are hurting our childern with petty conflicts.

Using iTunes and the iPad in the classroom

One of the schools that I support in our school district recently purchased two iPads. We need to establish iTunes accounts that do not have a payment method associated with them. We have setup the devices and are looking forward to downloading FREE apps from the iTunes store. We have attempted to create our Apple ID in two different manners:
1. Go directly to iTunes on the iPad and select a free app. Click download. Prompted to setup an account. Was not presented with the "none" option for payment.
2. Went directly into the iPad settings to "iTunes and App Store." Again, no "none" option for payment.
Our department does not have access to a credit card nor a gift card due to funding. I would appreciate any help that the iTunes department can provide to me about how to properly setup these iPads so that our students can utilize them in the classroom.
Regards,
Matt

Greetings fcit@!A,
After reviewing your post, it sounds like you are not able to select none as your payment type. I would recommend that you read this article, it may be able to help the issue.
Why can’t I select None when I edit my Apple ID payment information? - Apple Support
Thanks for using Apple Support Communities.
Take care,
Mario

What accessories are needed to connect my Apple TV to my LCD projector (VGA connectors) in the classroom so that I can mirror my iPad for around the class teaching?

I have been wanting to project my iPad to my class and the only way I have found is to use the connector. However, I would like to remove myself from in front of the classroom and move around the classroom. This encourages students to take notes and not pass notes. This also encourages them to engage in questioning of the lesson, because the teacher is not far removed from them if they're in the back of the classroom. How can I connect? I've read some forums that discuss converters and many who say it needs to be active or powered, but some of these powered converters are nearly two times the amount of the Apple TV. I wouldn't mind paying if this is the suggested way and it works. I don't want to go through several failed and expensive experiments.

There are hardware converters that will convert HDMI to various other types of output, however there are some issues with doing so that you should be aware of.
HDCP
HDCP compliant converters will not allow you to watch HDCP protected content such as that from the iTunes Store. Non compliant converters exist but we cannot discuss them under the Terms of Use for these communities.
Resolution and aspect ratio
I'm not aware of any converters that will scale the output from the Apple TV, any TV or projector which is used will need to be widescreen and support resolutions of 720p (if you are using the Apple TV 2)

Why do I get shadows in the corners of pictures taken on my mini iPad?

Why do I get shadows in the corners of pictures taken on my mini iPad. It seems the conditions have to be perfect to get a decent picture. Why?

Sounds like vignetting, but you need to ask that on an iPad forum not the iPhoto for Mac one.

How do I add a drop shadow to the page in Muse?

How can I apply a drop shadow to the page template in Muse? If I place a rectangle it will not change shape according to the page size. Is this a feature?

Hello,
You're most possibly referring to "Favicons", and they can be added in a Muse site from the "File -> Site Properties -> Layout" section. Check this screenshot: http://jingsite.businesscatalyst.com/jing/2013-09-05_2332.png
Hope this helps.

How can I use airplay in the classroom?

I want to use my iPhone in the classroom via airplay. How do I do this without having to pay for an airport express? Can I not just mirror the images wirelessly?

Hi
To use airplay you need an airplay capable device such as Apple TV and an iPhone that is 4s or higher, mine is only 4 so I can't access airplay. Once both the Apple TV and phone or iPad are connected to the same wireless notwork you will be able to mirror your screens.
I hope this helps.

How to put a repeatable shadow at the bottom of a wine bottle

I'll select an image of a bottle (beer or wine) and it's all nice and clean around the bottom, totally isolated from the background. I've asked Photoshop savvy friends how to do this and they all have come up with some workaround that is not repeatable. Check out this image from a wine makers' website: the shadow at the bottom is the same from shot to shot and I'm sure is added at the bottom in post, not when the bottle was photographed. How to do this?
Attached is an image of a bottle with shadow from the website and one of my own bottle images with no shadow. Remember, it's got to be a repeatable shadow that I can add to any "finished" image and not have to worry about selecting around the nebulous outline of the shadow. Thanks.

1) create a circle shape
2)squish the circle down to give it its shape
3)Move the shape layer below the image layer
4)Convert the shape layer to a smart object
5)Apply a guassian blur to the shape
6)Reduce the opacity of the shape layer
7)reposition the shape layer if needed.
The above assumes the bottle is on its own layer with no background
If necessary to remove the white background you can you the quick selection tool to select the white and hit the delete key. To make sure the bottle will be on a transparent background, you must unlock the image layer by dragging its lock icon to the trashcan before hitting the delete key.
Once all the steps above are done, you can apply a new background by either filling a new layer with a color and moving that layer below all other layers.
or
use the solid color adjustment layer and set its color to your choosing and then move that layer below all other layers.
Here is a quick example (logo of bottle has been pixelated)

I am a teacher and would like to know how to use the iPad in the classroom?

I am a teacher and would like to know how to use the iPad in the classroom?

Since this is a user forum you might wish to do some Google searching on your topic. There are hundreds of ways an iPad could be used in the classroom both by teachers and students. Apple is very much involved in education so you may wish to look further into their programs, but that is not done on the forums but through Apple's website. For example, Students - Mac, iPod, iPhone, and iPad for college and Education - iPod touch and iPhone enable on-the-go and Education - iPad makes the perfect learning ...

Drag and drop not working. When trying to move a cell or icon the shadow of the cell or icon being moved appears under the cursor but can't be released causing a freeze of function within the program. Happens in finder numbers and firefox

This is a serious pain.
Please help.

Yes, all I can tell you is that Finder does not have that function in ML. Your system is "working as expected".

I am a teacher that uses the iPad in the classroom. I have an itunes account setup for my classroom without a credit card listed. Is there anyway for me to purchase apps to use in the classroom with a Purchase Order?

(Being sarcastic - its because only the US is big or important enough to warrant volume licensing....)
At this time, until Apple decides to release volume licensing structures outside of the US the only solution would be to use your purchase orders with a company that sells the iTunes Vouchers and redeem those.
However - even then its hard to stay on the right side of the EULA when the terms are all couched in reference to "Personal Use"
I have spoken to some developers in the past about educational discounts, or even support for proxies, and wasn't really impressed with their answers. But hey - even Adobe has trouble with proxies and consistent approaches - we can't expect independent developers to be able to match the same capabilities...

I recently got an iPad and want to use it in the classroom toad in teaching history and geography, any suggestions on how to get started?

I assume you have a data projector to which you want to connect the iPad. You will need the appropriate lead. Is it written material you wish to display? What programmes is your information on?, eg, PowerPoint, Keynote, Pages, Word PDF's etc. A lot more information is required.

The event library and multiple users in the classroom

Is there any way I can stop the event library loading old footage or footage from another project in imovie. Is there any way i can have 3 or 4 movies on the go in separate files.
I have ten macbooks for my class of thrity kids. We have two users on the computer Admin and Student. All students use the student side, every time imovie opens it gets old footage and events from iphoto and by the end of each term there is 8 to 10 gigs of footage on the go at any one time. imovie HD allowed save, file open and movement of movies. imovie 08/09 seems brilliant for snow boarders and you tubers but not the classroom. Really we would love an editing package that allows attachment of camera and work for a couple of weeks on a project while others do the same thing on the same mac. Please don't suggest multiple users we have over 200 macs and 600 students.

Without multiuser, the only of having an exclusive event library for each student would be either external drive, or a blank disk image to store iMovie events. I can imagine a large network drive that has 50GB size disk images for each students. You mount your image to work with your footage.
By the way you can move event library to other drive within iMovie, so you can back up and disconnect external drive to unclutter event library.

My husbands iPhone 5 has a shadow up the screen how do I clear it?

I Have a iPhone 5 on IOS 7.1.2 and it has developed a long shadow down the screen today on all screens but it is not as obvious on the home screen.
how can I clear it?

Hello there, Biddy.
The following Knowledge Base article offers up some great recommendations for troubleshooting issues with the display on your iOS device:
Get help with the screen on your iPhone, iPad, or iPod touch - Apple Support
If you see lines, missing sections, discoloration, or poor image quality
Try to restart your device. If you can't restart, reset your device.
If restarting or resetting doesn’t fix the issue, restore your device.
If you still see the issue after you restore, contact Apple Support.
Thanks for reaching out to Apple Support Communities.
Cheers,
