Trouble with rotating..

Everyone out there that is good at math.. I have a problem. I'm working on making a basic 3d engine, and I cant seem to get it to rotate about the Y axis. I need a formula like
Xprime=X*(sin alpha) - Y*(cos alpha)
something like that. It can obviously use Z as well as X and Y. I'm haveing extreme trouble with this.. Thanks in advance.

I made a quick search for "rotation matrix" and found this,

The formula you're looking for is called: Rotation about z axis is: Rz

Why is iphoto having trouble with rotating photos all of a sudden?

i've been using iphoto for a few years. suddenly it un-rotated all of my auto-rotated photos (which screwed up all of my face tags) and now when i upload new photos, if they auto-rotate during the upload they appear in the preview of a whole event, but if i double-click to see a vertical photo, or try to do a slideshow, i get the triangle with an exclamation point in it, indicating that something's wrong with the file. is anyone else having this trouble? or have any idea what to do?
thanks...

I've never used the Flickr feature so don't know if that as any bearing on the problem. if you're satisfied with the newly "fixed" library you can delete the copy of the original library that you made.
However, since you're having problems with rotated photos you might try this and see if the new library has the rotated photos displayed correctly:
Start over from scratch with new library
Start over with a new library and import the Originals (iPhoto 09 and earlier) or the Masters (iPhoto 11) folder from your original library as follows:
1. Move the existing library folder to the desktop.
2. Open the library package like this.
Click to view full size
3. Launch iPhoto and, when asked, select the option to create a new library.
4. Drag the Originals (iPhoto 09 and earlier) or the Masters (iPhoto 11) folder from the iPhoto Library on the desktop into the open iPhoto window.
Click to view full size
This will create a new library with the same Events as the original library but will not keep the metadata, albums, books slideshows and other projects.
If the rotated photos display correctly in this new library then the problem lies with the orther libraries being damages somehow. You may want to stay with the new library even though the projects, i.e. books, etc. and keywords are lost.
If you have a lot of keywords in your current library and want to move them to the new library you can by doing this:
1 - open the old library and select one photo.
2 - type Command+K to brinb up the keyword pane.
3 - click on all of the keywords that are not blue so that all of the keywords are blue.
4 - export that photo to the Desktop via the File ➙ Export ➙ File Export menu option. Select Kind=JPEG and check the two check boxes regarding keywords, locations, etc.
5 - open the new library with iPhoto and import the exported photo from the Desktop. That will bring in all of the keywords so that you don't have to recereate them one by one in the new library.

Trouble with rotation Portrait-mode vs. Landscape-mode

Hi there, Maybe someone can give me advice on this, cause it's driving me a little nuts. When I take a picture with my iPhone 4S in portraitmode, when I store it on my computer, it's stored there in landscapemode. That is, the thumbnail shows the picture rotated counterclockwise in landscapemode, and so does every program (pictureviewer, photo gallery, internet explorer etc.) I use to open it. My Popcorn Hour C-200 -a mediaplayer- however is "smart enough" to show the picture in portraitmode. But here's the annoying part: when I correct this on my computer, turn the picture clockwise so it's in portraitmode, it shows correct on my computer, but now the image on my PCH C-200 is turned clockwise to landscapemode! How can I fix this? There is one picturefile from my iPhone that is correct in portraitmode, both on my computer and on my PCH C-200, but I don't know what I did differently with that one. But I now know it can be done...

Unlock your screen orientation. Double click home - swipe all the way to the left and unlock your orientation.

Having trouble with iphoto, will not print full image

Having trouble with iphoto on my laptop and desk top computers. On laptop will not let me print full image and having trouble getting correct rotation to print
On desk top printing too dark and cannot get correct rotation there either, seems like the problem just started recently

Ronleedek-
What App are you using with the microphone? I've used Skype, which has a "test call" feature to check your microphone.
There is a good chance your microphone is defective, possibly disconnected inside the iPad. If an Apple Store Genius can not fix it, you may get a new iPad on the spot.

Trouble with image size

Hello everyone, I'm having some trouble with image sizes.
I created a 977x5000 px image at 72 PX/inch resolution with text for use on a weebly website.
When created the image looks like a small vertical bar(maybe around 50x500px) with a massive left and right photoshop background(not the image background). so if I drag the bottom slider to the left or right the image will completely disappear. I can CTR and + to get it to the correct size so I can actually read the text. I can still go very far left and right with bottom slider. The problem comes in when I save it to a PNG or other file it still shows up as a bar.
Is there any way to fix this so it saves it as the correct viewing size? that way when I open the image it's an actual 977x5000 instead of looking like a 50x500
I'm on Windows 7, my display settings are at 100% and I'm using Photoshop CC 2014

You do not understand what is going on at all. First an image file's PX/inch resolution setting is meaningless when it come to the Web and displays all that is meaningful is pixels. For displays are run at one resolution usually their native manufactured Pixel resolution so your image will be displayed at 96DPI on Desktop Displays and a 300+DPI on Phones and around 250DPI on tablets. Your image height is also to large to fit on any display. The Display I think that displays the most pixels is the IBM T221 22.2" LCD 16:10 aspect ratio 3840px by 2400px. at 204DPI. Rotating that display to portrait it can display an image with a height of 3840px your image height is larger 5000. Your image has an aspect ratio in the neighborhood of 1:5 an image 50x500 has an aspect ratio of 1:10 a far cry from 1:5 your image is much wider then 1:10.

Trouble with spacing of divs vertically

Hi all,
I am having trouble with CSS and vertically stacking my divs, In the following code there are a number of identical divs and I want them to stack one upon the other like in a list. At the moment I need to hit returns after each div to get below the one above and it puts way too much room in between each div doing this. I am at a loss how to do set the amount of spcae between them and also to make one go directly below the other.
Any and all help greatly appreciated
Thanks Rick

Troubles with launching Java GUI from C++

Now here's the interesting thing: in the constructor of my Java class there's a call to pack() to initiate my Java GUI. When I remove that call everything works fine (but then I haven't got a GUI though). setVisible(true) in the Java code also gives that problem.
Has C++ or the Xm library some troubles with the Java GUI? Or what the hell is going wrong?
PS: On Solaris, the very same code works perfectly...

I really need a solution.
Is it possible it has something to do with threads?
Do I have to do AttachCurrentThread or something like that? Is that necessary?
Btw, I assigned 10 duke dollars to this topic.

I have been having a lot of trouble with the latest itunes update and my ipod classic 80Gb i.e. being unable to sync songs, but now i have no files at all on my ipod, it is completely blank when i view it from my computer. I need help, please, anybody.

As it says above, i have been having a lot f trouble with my ipod classic and the latest itunes update, i was unable to sync songs or anything to it and have tried every conceivable 'fix' i could find. i have run an itunes diagnostic and the results are posted below. a major problem is that when i try and view my ipod through my computer it displays nothing at all on the ipod, no files or anything, this may be the problem but i have no idea how it has happened or how i could resolve it.
This ipod holds huge sentimental value and i am loathe to buy a new one! If anybody can help it is greatly appreciated, than kyou in advanced.

Searching on the web, most results I found lead to this page, where it is said that the problem is due to badly tuned overcurrent protection, and advocated that unplugging and switching off the computer for a little while gets things back into normal. This does not really work for me; the problem seems to occur more randomly, unfortunately with high probability (my camera is available after less than one boot out of ten).
I tried to ensure that the ehci-hcd module is loaded at boot with the ignore-oc option (with a file in /etc/module-load.d/), to no avail.
I also wrote a script which alternatively removes and reloads the ehci-pci driver until my device is found in lsusb. It is sometimes helpful, but usually not. And even when my device is found that way, it can only be used for a while before disappearing again.
Anyway, such a hack is unacceptable... So, my questions are:
is it indeed related to overcurrent protection ?
is there anything else I can try ?
should I file somewhere an other of the numerous bug reports about "unable to enumerate USB device" already existing ?
If of any importance, I am running linux 3.15.7, because at the time I installed my system, I couldn't get the hybrid graphic card Intel/AMD working under 3.16.

Hello Sue,
I have an iPad 3, iPad Mini and iPhone 5S and they are all sluggish on capitalisation using shift keys. I hope that Apple will solve the problem because it is driving me crazy.
I find using a Microsoft Surface and Windows 8 phone, which I also have, work as well as all the ios devices before the ios 7 upgrade.
It has something to do with the length of time that you need to hold the shift key down. The shift key needs to be held longer than the letter key for the capitalisation to work. For some reason, this is a major change in the way we have learnt to touch type on computers. I am having to relearn how to type!

Trouble with OR in where clause

Hello,
I'm having trouble with execution speed. The problem seems to be with using OR in my where clause.
Here's the meat of the function where i_pledge_number is an input parm:
BEGIN
SELECT /*+ INDEX (pp) */ SUM(pp.prim_pledge_amount)
INTO return_amount
FROM
primary_pledge pp
WHERE
-- Get total if multiple allocations
pp.prim_pledge_number IN
(SELECT pc.pledge_number
FROM pledge_codes pc
WHERE pc.pledge_code_type = 'M'
AND pc.pledge_code = 'AC'
AND lpad(pc.pledge_comment,10,'0') = i_pledge_number)
-- Get total if single allocation
OR pp.prim_pledge_number = i_pledge_number;
RETURN return_amount;
END;
If I comment out either half of the OR statement (either the subquery or the pp.prim_pledge_number = i_pledge_number half) the function returns a value in .02 seconds. If I leave the OR in, it takes 2.764 seconds to execute?? Can someone please show me a better way (faster) to do this? I tried using nvl() around the subquery but couldn't get it to compile.
Thanks

These things are difficult to diagnose remotely, but here is something you can try....
SELECT */ SUM(pp.prim_pledge_amount)
INTO return_amount
FROM   primary_pledge pp
WHERE pp.prim_pledge_number IN (SELECT pc.pledge_number
                                 FROM pledge_codes pc
                                 WHERE pc.pledge_code_type = 'M'
                                 AND pc.pledge_code = 'AC'
                                 AND lpad(pc.pledge_comment,10,'0') = i_pledge_number
UNION ALL
SELECT i_pledge_number FROM dual)
   RETURN return_amount;
END;If that doesn't do anything (and it might well not) there are a large number of different ways we can recast this query. To save us further guessing please give us more details: execution plans, database version number, volumetrics.

A trouble with "LIKE" in a select statement

Hi!
I'm having trouble with "LIKE" in a select statement...
With Access I can make the following and everything works well:
SELECT name, birthday
FROM client
WHERE birthday LIKE '*/02/*';
but if try to do it in my application (it uses Access), it doesn't work - I just can't understand that!!!
In my application the "month" is always the currently month taken from the "System". Look what I'm doing...
String query1 = "SELECT name, birthday " +
          "FROM client " +
          "WHERE birthday " +
          "LIKE '*/" +
          pMonth +
          "/*' " +
          "ORDER BY birthday ASC ";
ResultSet rs = statement1.executeQuery(consulta1);
boolean moreRecords = rs.next();
The variable "moreRecords" is always "false", the query returns nothing although the table "client" has records that attend the query.
Please, anyone can help me?! It's a little bit urgent.
Thanks,
Katia.

Hi Katia,
I'll bet the problem lies with the characters you're using to escape the LIKE clause. You're using the ones that Access likes to see, but that's not necessarily what's built into the JDBC-ODBC driver class.
You can find out what the correct escape wildcard characters are from the java.sql.DatabaseMetaData.getSearchStringEscape() method. It'll tell you what to use in the LIKE clause.
I'm not 100% sure about your code. It doesn't use query1 anywhere. I'd do this:
String query = "SELECT name, birthday FROM client WHERE birthday LIKE ? ORDER BY birthday ASC";
PreparedStatement statement = connection.createStatement(query);
String escape = connection.getMetaData().getSearchStringEscape();
String test = escape + '/' + pMonth + '/' + escape;
statement.setString(1, test);
ResultSet rs = statement.executeQuery();
while (rs.hasNext())
// load your data into a data structure to pass back.
rs.close();
statement.close();Let me know if that works. - MOD

(Trouble printing) Trouble with connection between Macbook Pro and Hp Deskjet 1510.

Trouble with connection between Macbook Pro and Hp Deskjet 1510. (Nothing Prints).
I have a Macbook Pro and am having difficulty printing documents from ‘Pages' from my Hp Deskjet 1510. I have installed the necessary software for the printer and it is connected via USB. Every time I try to print the printer icon comes up as it should, 'printing' and then 'job completed' and then the icon disappears. (Nothing is printed.) I thought it might be something to do with Pages compatibility with the printer but exporting the document to Word or making it a PDF doesn’t change anything. I don’t have Microsoft Word on my computer. The scanner does work and when I printed a ‘Test Page’ that worked too.
Let me know if you know why this is happening.

With these settings the network now works flawlessly, however, when i have my ethernet cable plugged in, my internet access via my airport card(on the macbook pro) is no longer available. Hoping you can tell me why this would be with this info i've provided.
Educated guess. The networking devices have priorities as to which are used. The standard order is that Ethernet has a higher priority than Airport.
While your Ethernet is unplugged it is inactive and the Mac ignores it. Once you plug it in, the Mac sees that it is active and switches traffic to that interface.
I actually take advantage of this feature at home, but configuring my Airport and Ethernet with identical fixed IP addresses. Normally I'll use Airport, but if I'm copying a huge file and I want faster performance, I'll just walk my MacBook (previously iBook, previously Powerbook) over to my Ethernet switch and plug in my MacBook. Magically, the Mac detects that the Ethernet is active and continues the file transfer uninterrupted over the faster 100baseT Ethernet connection. When the transfer is finished, or if I really need to move back to the Comfy Chair, I unplug the Ethernet cable, and all activity reverts back to the Airport, all without disrupting any existing networking connections.
You on the other hand have totally different settings for your Ethernet and your Airport, so when you switch to Ethernet, you basically loose your Airport connections.
Something you can try:
System Preferences -> Network
Gear icon on the bottom left, next to the [+] [-] icons.
Select *Set Service Order...*
Now Drag the network interfaces into the perfer priority order you want. In this case put Airport above Ethernet.
NOTE: You may want to create a new Network Location for this, instead of messing with your normal home Location (which is most likely the default Automatic. That way you have your original you can always fall back to.
