Bug figured out! new one made...
I posted earlier that I had collision detection active on a BranchGroup, and when I went to remove that branchgroup, I'd get an internal nullpointerexception, and the program would completely freeze. I discovered that the armingNode I was using to instantiate WakeupOnCollisionEntry was a transform group and not the actual geometry. When I changed it to the actual geometry, the branchgroup can be properly removed.
But! When I did this, collision detection doesn't seem to work quite right anymore. I have several objects with multiple geometries always colliding (like a turret in a tank, a simplication is to have the turret just sticking out of the base, so, in effect, it is colliding). Now that the armingNode is the geometry and not the transformgroup, none of the objects that are previously colliding can detect new collisions. Are there any workarounds that anybody knows of, short of writing my own collision detection?
Thanks!
java3d has not enough capabilities for detecting collisions.In your application how many collisions occur in a certain time. If it's more than ten it exceeds the capabilities of java3d. Also are the objects that have collsion behaviors moving so fast in the scene ? If they are , no chance for recognizing collisions . good luck again to all working with coll.sion detection .

How to check 2 tables(Table A and Table B) and figure out new columns present in Table A and add these new columns to Table b.
DDL-
Create table A
( A INT,
B INT,C VARCHAR(2)
Create table B
A INT,
B INT
Any advice on the best approach or method to achieve this.
I understand that I need to check the schema of the columns and then do a match between 2 tables and find new columns and then alter my target table
MudassarCan you try this..
CREATE TABLE A ( A INT, B INT, C VARCHAR(2) )
CREATE TABLE B ( A INT, B INT )
Declare @ColumnVar nvarchar(128),@DatatypeVar nvarchar(128)
SELECT @ColumnVar=x.COLUMN_NAME, @DatatypeVar=x.DATA_TYPE
FROM INFORMATION_SCHEMA.COLUMNS AS x
WHERE TABLE_NAME = 'A'
AND NOT EXISTS ( SELECT *
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = 'B'
AND COLUMN_NAME = x.COLUMN_NAME )
Declare @SQL VarChar(1000)
SELECT @SQL = 'ALTER TABLE B ADD ' + @ColumnVar + ' '+ @DatatypeVar
Exec (@SQL)
select * from B

Local File Album Art Bug (Figured Out)
I recently posted about this bug, but I now believe I have figured out what is the cause of it happening. For summarize, there is a bug that appeared in the newest version of Spotify (1.0.5.186) that causes the album art to not show up on certain Local files. When playing a song with Album art that doesn't work, Spotify will instead show the album art of the song that was previously played still. (Clean reinstallation does not solve this) What I've found to be the cause is that certain symbols that can either be found in the tracks naming or in the main file itself for some reason causes this to happen. The two symbols I've found to mainly cause this is apostrophes and parenthesis (There might be more). Since it's not much of solution to remove all these symbols from the files' names (As it would take a long time and ruin the name of some songs), this bug still needs a fix, but I hope this can somehow contribute to making the problem easier to solve :smileyhappy:
Hey
Thanks for your post.
Are you still having trouble with this? If so, could you let us know the version of Spotify that you're running at current?
Also, could you let us know the version of OS you're using on your device?
We'd love to forward this onto our team here!

I upgraded to the new iCloud storage plans made available yesterday and saw that today apple is upgrading people's plans and providing a prorated refund. Since I upgraded myself, am I no longer eligible for the prorated refund on my legacy account?
It's always been the case in the past that when upgrade the storage plan the subscription is dated from the day this is done, and the unexpired portion of the previous subscription year is credited against the cost. How this will work with the monthly payment I don't know, but I can't see them not refunding an unexpired portion in some manner. If it's a credit to your credit card it can take some days to come through. It's not been in the past, but we're in new territory here.

Who are these discussions for? Seems like a good place for Verizon to figure out who is mad.
I need/want answers to how to STOP being treated (for the most part, there ARE exceptions). If needed how to end my contract without going through the ringer and see what other "actions" others are doing.
Thank you.AZSALUKI,
But, they continue to tell me that i need to pay the fee, because I signed a "contract". Over the past couple of years, they have replaced phone after phone, etc. and only said sorry. In fact, I just got off the phone with them, and their offer was to ship me out another phone. That is the problem. So, THEY in fact have NOT fulfilled THEIR end of the contract. Thus, I should be able to leave WITHOUT paying them..... Correct?
Onceagain, I am looking to "the group" as to how "we" are going to handle the problem.
Oh, by the way, I did offer up another solution for them this morning. Have a person from the store come to my location (all of 2 miles), and they said "no". So, they are NOT working with me.
So, please enlighten me. -
Weak wifi signal or range... can't figure out which one.
I just set up my self-install kit today. Everything went well, until I tried to use the internet on my computer. The only place for the modem is downstairs, but my office is upstairs. I've had AT&T for over a year, and it has never been a problem, but with Comcast, my pages rarely load, and if they do, it takes an insane amount of time to do so. I switch back and forth between AT&T wireless and Comcast wireless to see the difference, and it def has something to do with Comcast. The signal strength ranges from "good" to -"very good", but there's not much of a change in connection. What are my options to fix thsi problem??
I assume you have one of the comcast gateway devices they are known for very poor performance. If you dont have there phone service i would return the gateway and buy your own modem and high quaility router and things will improve greatly and you will save 10.00 a month on rental fees. If you have there phone service you could also have the gateway placed in bridge mode and then use your own high quality router.

Can't figure out these anomalies. Driving me nuts.
The following code for the BouncingBalls assignment results in some anomalies that I can't figure out.
The main problem is that there SEEM TO BE different responses: the balls reverse direction at the right and bottom, but not top and left. In the code I have shown two different statements: one for dx, (which seems like it should work, but doesn't) and the one for dy, (which reverses direction properly, but the d? value is not the one that I want to change, only the direction modifier needs to change.)
The dx one is the one that I think should work, but the dy variation provides reversal. Since both variables are in the same formula, I can't figure out why one works, one doesn't.
The other anomaly is that Ball4 doesn't behave as the other three. What the hell's going on.....a tribute to Jim Bouton???
Any suggestions on where to start looking for the bugs would be appreciated.
Thanks.

// End main BouncingBall FileHold up. You are making this way to complicated. Whats the point of dir_x and dir_y? Nothing. Remove them.
Do this:
When the ball bounces on the top or bottom.
dy = -dy ;
When the ball bounces on the left or right.
dx = -dx ;
Also, you might want to put some math in to force the ball to be within the box when a bounce occurs, if you haven't already. Just translate x and y over a bit.
You have way too much garbage in your move method... all those extra variables are what confused you. -
Data usage skyrocketing and I can't figure out why
I've been watching my AT&T data usage recently. I have the original iPhone and had expected to replace it this year. That will apparently cause me to lose the unlimited data plan, as per AT&T's latest announcement.
For some reason my usage, which used to run about 70-100MB/month, is getting towards the 1 GB level and climbing. Last month it was 770 MB. My bill details only show data "out," nothing "in." Most nights around 2:30 a.m there is a lot of activity, anywhere from 60KB to 80,000KB At that time the phone is asleep (as I am) and charging -- but not connected to a computer.
I've turned off Push email (which disables "find my Phone.") I have all app notifications turned off. My phone does not have GPS. I have wi-fi at home, but a lot of data transfers seem to be at times during the day when I believe I am connected via wi-fi. Except for the occasional App Store purchase on the fly, I download from iTunes to my Mac and sync with USB cable.
I do have 4 email accounts besides MobileMe and I retrieve mail manually to save battery life.
With the 2G iPhone on Edge, I cannot do streaming video and other things that I would want to do with a more capable phone. I am paying $99/year for MobileMe and have been advised to cripple it. AT&T customer support suggested that apps are the problem, but gave me no guidance on figuring out which apps might be the culprit(s). My understanding is that the iPhone doesn't allow apps to run in the background. I know Apple doesn't update without permission. I am not subscribed to any AT&T services that I know about.
I just want to understand how this all works. If there are some apps that are misbehaving, how do I figure out which ones? I do not want to get an expensive new iPhone and find out I can't afford to enjoy it.
I have restored the phone to factory settings twice in the past four months on advice from Apple.
Does anyone have any thoughts on this?ksujeff99 wrote:
I have the exact same issue, as do some other people at the end of this macrumors thread. http://forums.macrumors.com/showthread.php?t=576888
I have MobileMe and 3 other email accounts but I don't think that's the issue. My 3GS is consistently doing accessing the 3G network middle of the night when I have a full WiFi signal from my home network. There is no reason that I should have any data activity during this time.
A Mac Genius told me that when the iPhone goes to sleep, wi-fi is disconnected. This means the phone is then on the cellular network. In my mind that is a design flaw. The phone goes to sleep to reduce energy usage, but the cell network uses more energy than wi-fi. That's a separate question from the data use issue, which is relevant for several reasons: cost, user control and privacy. -
Trying to figure out which older GPIB I have
I have an old GBIB I want to put in a new Dell computer, Win2000. I know I need to download new drivers, but can't figure out which ones. The GPIB is marked 429C(handwritten) 488EX. A small sticker is marked NEC REV Q 0295. Thanks.
Hello,
Sometime's it's the simplest answer.
We were told our computer had a NI GPIB. After your response, I checked again and found CEC on the board. A quick internet search and I found the manufacturer.
Thank you for your quick response. I really appreciate it! -
Figuring out the correct icloud account
We had to "clear"out our sons iphone 4 (which is not connected to service) because he forgot his password. He's using it like an ipod. When we did this and tried to set it up it is asking us to conncect to an icloud account - but we can't figure out which one. None of our other 3 devices are set up to the one it's prompting us to nor will it recognize the icloud account that it was origanally linked to. Any suggestions?
Thanks Roger this is uncouraging. I went into my iDisk and I found two things. A folder called Istvan's site that opened to a folder called Blog to a file called rss.xml. This file would not open after I downloaded it. The other thing in the same location was a file called sites.rss that I was able to open. I'm hoping that is the one I need to change. Is it?
The very start of the code has the channel and item tags like you mention in your instructions. Here it is:
<?xml version="1.0"?>
<rss xmlns:admhp="http://www.apple.com/DotMac/Homepage" version="2.0">
<channel>
<title>i.am.istvan</title>
<description></description>
<link>http://web.mac.com/i.am.istvan/iWeb</link>
<item>
<title>Blog</title>
If in fact this is the file I need to alter do I replace the three lines between the two tags with my new location? Or do I do something else? Why do I feel like I'm about to cut the wrong wire? Thanks Roger. -

I can't figure out how to turn them back on, please advise, thanks.Try the Firefox SafeMode. <br />
''A troubleshooting mode, which disables most Add-ons.'' <br />
''(If you're not using it, switch to the Default Theme.)''
# You can open the Firefox 4/5/6/7 SafeMode by holding the '''Shft''' key when you use the Firefox desktop or Start menu shortcut.

''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before using the Firefox shortcut (without the Shft key) to open it again.''
If it is good in the Firefox SafeMode, your problem is probably caused by an extension, and you need to figure out which one. <br />

I can't figure out to print any webpage.
I do not see any print button and the pull down menu (after clicking the mouse) does not include a printing option.
Thank you!It could be that one of your add-ons is preventing the button from showing up. First, go to the Firefox button > Help > Restart with add-ons disabled. If that fixes the problem it means one of your add-ons is the cause. See [[Troubleshooting extensions and themes]] for steps to figure out which one.

A while back I made a gamecenter account that was not associated with an Apple ID, it was with my email, now my gamecenter account IS my Apple ID. I want to delete it and make a new one, but i can't figure out how. Help!
Since you can't delete Apple IDs and having multiple Apple IDs can cause confusion, what you may want to do is rename your existing Apple ID to the new email (desired Apple ID). That would in effect do what you want, get rid of the old and give you the new.
