Hi! I´m having problems with showing video files in Qlab on my Macbook Air. It started suddenly. Consulted a sound/video technician who told me to "blow out" my Mac. Was told to use cmd+r when restarting. Is this the right way to clean up my Mac? And is it likely that some kind of bug is causing problems for Qlab to show video files? I´ve already tried with a bunch of different video files and sometimes Qlab plays them and sometimes not. I need the Qlab playlist for a theatre show and only have a week until showtime so starting to really worry. Is there anyone out there who can help?
Your Mac runs maintenance in the background for you.
Command + R gives you access to restore, repair, or reformat the drive using OS X Recovery
No idea why that was suggested.
You may have a third party video player installed that's causing an incompatibility issue.

Thread safety! Is this the right way?
Hello,
Lately I'm reading lot about thread-safety in Swing...
so just wondering that is this the right way to code ...
For ex following code executes(which makes DB connection and load some list) when user press the "connect (JButton)" ....
private void prepareAndShowConnBox()
//System.out.println("prep - EDT: " + javax.swing.SwingUtilities.isEventDispatchThread());
pwd.setEchoChar('*');
javax.swing.Box box1 = new javax.swing.Box(javax.swing.BoxLayout.Y_AXIS);
javax.swing.Box box2 = new javax.swing.Box(javax.swing.BoxLayout.Y_AXIS);
box1.add(new javax.swing.JLabel("DB URL : "));
box2.add(db_url);
box1.add(new javax.swing.JLabel("User Name : "));
box2.add(uid);
box1.add(new javax.swing.JLabel("Password : "));
box2.add(pwd);
final javax.swing.Box box = new javax.swing.Box(javax.swing.BoxLayout.X_AXIS);
box.add(box1);
box.add(box2);
int retval = javax.swing.JOptionPane.showOptionDialog(me, box,
"Database Connection:",
javax.swing.JOptionPane.OK_CANCEL_OPTION,
javax.swing.JOptionPane.QUESTION_MESSAGE,
null, null, null);
if(retval == javax.swing.JOptionPane.OK_OPTION)
status.setText("Connecting...");
Thread t = new Thread(makeConn, "Conn Thread");
t.setPriority(Thread.NORM_PRIORITY);
t.start();
}And the makeConn is....
private Runnable makeConn = new Runnable()
boolean success;
Exception x;
public void run()
//System.out.println("Con - EDT: " + javax.swing.SwingUtilities.isEventDispatchThread());
success = true;
x = null;
try
//load sun JDBC-ODBC bridgr driver...
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
//make connection to DB...
con = java.sql.DriverManager.getConnection("jdbc:odbc:" + db_url.getText(),
uid.getText(), new String(pwd.getPassword()));
catch(Exception e)
success = false;
x = e;
System.err.println(x);
java.awt.EventQueue.invokeLater(GUItask);
Runnable GUItask = new Runnable()
public void run()
//System.out.println("Con gui - EDT: " + javax.swing.SwingUtilities.isEventDispatchThread());
if(success)
bConn.setText("Disconnect");
status.setText("");
status.setIcon(imgLink);
imgLink.setImageObserver(status);
//load the pic list...
Thread t = new Thread(execQuery, "List1 Thread");
t.setPriority(Thread.NORM_PRIORITY);
t.start();
else
status.setText("Connection Failed.");
showErr(x.toString());
};Here uid,db_url (JTextField) , pwd (JPasswordField) , status (JLabel) are class fields.
Thanks for any comments... :)Threading looks fine too me... the connection is created on a background thread, but (critically) all GUI updates are performed on the EDT, even if there's an exception. Well done.
My only comment is... why is your GUI creating a database connection at all? Ideally the controler would get the DAO (which would connect itself) and inject it (the connected DAO) into the view... but I'm a server-side boy, so feel free to ignore me.

I have schema 'A' with few large and many small non-partition tables. I created another schema 'B' identical to 'A' and the only difference was that I partitioned the large tables resulting a combination of partitioned and non partitioned tables in schema 'B'.
I exported schema 'A' and imported it into 'B'. My question is, IS this the right way or I should done something else.
ThxIt would depend on the your goals, but I'd suspect that you would want to create most of the same indexes and views in the new schema. If you're partitioning the tables, though, you would have to give serious thought to how to define the indexes-- should they be global or local, should they be equipartitioned with the underlying tables, etc.-- which exporting and importing wouldn't resolve.
If the end goal of this exercise is just to produce the same schema with partitioned tables, transition any code & applications to the partitioned schema, and then drop the unpartitioned schema, creating the new schema just adds extra work. Create partitioned tables in the same schema (with slightly different names), load the data, create appropriate indexes, and then ALTER TABLE ... RENAME everything so that the partitioned tables now have the old non-partitioned table names.

Being Nice to your Layout manager - Is this the right way?
Ive written a custom component that basically provides multi-line text wrapping and a few other nice things.
I had a bit of trouble when I came to implementing
getPreferredSize() getMinimumSize() This is because ideally, I'd like the component to use as much space horizontally as possible, whilst using only as much vertical space as necessary.
To do this, I used the parents width as the minimum horizontal size. This then allowed me to work out the height.
Question is - is that the right way to do it? Other than that, I just cant think of a way to get the width I need when the component is first added to its container.
Cheers for any input,
DaveIf you want it to use as much horizontal space as possible, that means you want its width to be equal to its container's width (perhaps minus a bit for borders or something). So in that case you would have to set its minimum width to that number, and that's exactly what you did. There could be other ways to do it, but yours seems perfectly fine to me.

Hi everybody. I have recently started having problems with iCal (Version 2.05 (1069). Events that I thought I had deleted appear in Print Preview and Print Outs. Likewise Events that I have not deleted have disappeared from my calender (Month View) but appear in Print Preview and Print Outs. I see that there have been similar problems with Events disappearing especially in Month View. I wondered how print preview seemrd to be picking everything up deleted or not, and what the solution may be?. First time of Posting. I hope I haven't embarassed myself.
Hmmmm.
At the very least there must be a "com.apple.ical.plist"...iCal would not function without it.
Click on the Finder icon in the dock
Click on Go > Home
Double-click Library
Double-click Preferences
Look for a file called "com.apple.ical.plist" and remove it to the trash. -
I have all my previous music files in wma formats from my previous PC Windows xp computer. And only two weeks ago I decided to purchase an iMac computer OS X Maverick, and there are a lot of files and information I would like to bring to the Mac, but I'm having problems playing my music file, suited to the PC but not with iMac as yet. So, I hope you can help on this...
Kind Regards
Robert KlaassenWMA files are 'window media audio' files, which is a Microsoft format. If you want to add them to your iTunes library on your Mac then you will need to convert them into a compatible format first. If you still have your windows machine then iTunes for Windows can convert them from WMA to MP3 format : https://discussions.apple.com/message/24158701#24158701
Or try a search for, for example, 'convert wma to mp3' to find programs to convert them. -
i am having problems with Olympus .orf which cannot be read by Elements 10 and Lightroom 4. Both provide an error message saying that the file is not recognized. Any ideas? minzen
That camera model is too new for your programs. Every camera has its own raw format and ACR must be updated to include the info for each new model as it comes out. The workaround would be to download the free Adobe DNG converter and use that to convert your ORFs to DNGs that your version of Camera Raw can read.

Is this the right way to use Methods on Table - Get Procedure
Hello,
I just would like to make sure that the following is the use for which
we use Get Procedure in Table API Package. ? And are there other use cases ?
If we create a package on EMP Table, we get few Procedure .eg : Insert , Update, GET
We use Get procedure when having few forms on different Tables on one page
to manually fetch the values instead of using Automatic Row Processing (DML) .
In PL/SQL process - On Load After Header. this code goes :
BEGIN
EMP_PKG.GET_EMP (
:P3_EMPNO,
:P3_ENAME,
:P3_JOB,
:P3_MGR,
:P3_HIREDATE,
:P3_SAL,
:P3_COMM,
:P3_DEPTNO
DEPT_PKG.GET_DEPT ( .......

Actually, I got the idea when skimming PL/SQL best practice book. I agree with with Steven Feuerstein on most of his PL/SQL best practices, but not on the use of TAPIs.
There was a cancelled webinar by Dan - Taking Control: Integrating PL/SQL APIs with APEX.

The abstract doesn't specifically mention TAPIs, but if that's the approach he was going to present then I'd disagree with it.

Problems with hotmail re. sync. contacts & email on Iphone & Macbook Air
HI,
I have an Iphone 5c and a macbook air and I use a hotmail account. Problems that I encounter:
- hotmail: emails arrive on all devices but do not sync, for example when I delete emails on one device I also have to do this manually on another device
- contacts: contacts on Iphone do not sync with macbook air
(I use Imap for hotmail).
How to solve this? Now thinking about exchanging hotmail account for Icloud email account. Will this solve both problems?
Kind regards,
BrigitteHello. Do you see all accounts in "Mail, Contacts and Calendars?"
If you do, make sure you have hecked the boxes of the feartures of each account to work on your Mac. Example, I have a Google account, and when I click on it, I can select if I want to sync Mail, Calendars, Notes or Messages.
Please take note that I am referring to setting them up on the MacBook Air and not the iPhones.
Hope this helps. -
i Can't upload my videos from my iphone 4s to my computer, what software should i use to do this?
As far as I know you can't delete the primary email address for an iCloud account. It's assigned when the account is created. But your neighbor wouldn't have been able to get into your iCloud account without your Apple ID and password. Are you sure the account wasn't still on your phone when you gave it to him?
You could migrate a copy of your data to a new iCloud account but I would still be concerned that someone else was using my old account, which presumably still has your data in it.
I'm fairly certain that you're going to have to have iCloud support help you sort this one out as they may have the ability to make changes to an existing account that users can't. Make an appointment with the genius bar at a nearby Apple store and have them take a look at it. If necessary, they should be able to contact iCloud support for you. -
Is this the right way of using Enhancement spots?

<i></i>Hi nirre,
That's right.....
In general the thumb rule for this is:"
The enhancement implementation should be complete, let me clear with this example:
data:
begin of xy_12_12,
x12 type i,
y12(2) type c,
end of xy_12_12.
now if i want to enhance the code via implementing the implicit enhancement spot, that implementation should be complete in itself.i.e
begin of xy_12_12,
x12 type i,
y12(2) type c,
>>
data : e12 type i.
<<<
end of xy_12_12.
Hope it will clear the concept.

Is this this the right way to join them?
i have 3 tables basically liked
create table Sales_person
SalesPersonID
TransactionID
create table Customer_Sales
CustomerID
TranactionID
create table Sales
TransactionID
SoldDate
SalesItemID
SoldAmount
SoldQuanity
If I want a resulting table that show all the sales, sales person, and customer
SalesPersonID
CustomerID
TransactionID
SoldDate
SalesItemID
SoldAmount
SoldQuanity
would a sql statement like the following work?
select *
from sales s
LEFT join Customer_sales cs
on s.transactionID=cs.transactionID
LEFT join Sales_person sp
on sp.transactionID=s.transactionID
how is it different than
select *
from sales s
INNER join Customer_sales cs
on s.transactionID=cs.transactionID
INNERjoin Sales_person sp
on sp.transactionID=s.transactionIDBoth versions will "work", that is, they are syntactically correct, but it depends on what you really mean by work. The two queries are asking different questions and whehter either, both, or neither are correct depends on the the data in the tables. Your first query is an outer join, while the second is an inner join.
What the first query says is give me all of the rows in the sales table, and if there is a matching row in customer_sales give me the customer_sales information, otherwise make up a row with null in all columns, similarly for the sales_person table, if there is a match, give me the data otherwise make up a row.
The second query says give me all of the rows from the sales table where there is a matching record in both the customer_sales table and the sales_person table. If either join fails, then that sale will not be returned by the second query.
So, if it is possible that a sale could be made to a "non-customer" (i.e. no row in the customer_sales table), or not made by a sales person (i.e. no row in sales_person table), then the two queries are different.
Consider this simplified data set against your first query:
SQL> WITH
2 sales_person AS (
3 SELECT 1 salespersonid, 100 transactionid FROM dual UNION ALL
4 SELECT 1, 101 FROM dual UNION ALL
5 SELECT 2, 102 FROM dual),

13 SELECT 102, 30 FROM dual UNION ALL
14 SELECT 105, 50 FROM dual)
15 SELECT *
16 FROM sales s
17 LEFT JOIN customer_sales cs
18 ON s.transactionid = cs.transactionid
19 LEFT JOIN sales_person sp
20 ON s.transactionid = sp.transactionid;

101 25 11 101 1 101
102 30 12 102 2 102
105 50and against you second query:

2 sales_person AS (
3 SELECT 1 salespersonid, 100 transactionid FROM dual UNION ALL
4 SELECT 1, 101 FROM dual UNION ALL
5 SELECT 2, 102 FROM dual),

Implicit Fact Column - am I thinking about this the right way?
My exploration of the Implicit Fact Column is below. Let me know if you think this is the intended usage.
When the BI Server sees a request where one Dimension is being constrained by another, it has to pick a fact table that contains references to these two dimensions. The "Implicit Fact Column", which is set in the Presentation Layer of the RPD is used to guide the BI Server towards one or more Fact tables that can be used to satisfy the request. In the absence of the Implicit Fact Column, I noticed that the BI Server was choosing random fact tables so I went exploring how this feature worked. I set the Implicit Fact column in my Presentation layer and then went looking to see how the queries were generated.
For my example, my two dimensions are Program and Channel. I want to see the list of Channels available for a Program. Without the Implicit Fact Column, the queries are of the form:
select distinct T289.CHANNEL_NAME as c1,
T36001.PROGRAM_NAME as c2
from
DIM_PROGRAMS T36001,
DIM_CHANNELS T289,
SomeRandomFactTable T41210
where ( T289.DIM_CHANNEL_KEY = T41210.DIM_CHANNEL_KEY and T36001.DIM_PROGRAM_KEY = T41210.DIM_PROGRAM_KEY )
order by c1, c2
The nice part about this is that there is only one set of Program / Channel combinations returned. The downside is that the Fact table that is chosen to resolve the combinations can be any Fact table under the purview of the BI Server. It doesn't even have to be in the same subject area where the Program and Channel were chosen. When I set the Implicit Fact Column, the queries are of the form:
select distinct T289.CHANNEL_NAME as c1,
T36001.PROGRAM_NAME as c2,
T35832.DIM_SITE_KEY /* this is the implicit fact column */
from
DIM_PROGRAMS T36001,
DIM_CHANNELS T289,
AFactTableMappedToFactColumn T35832
where ( T289.DIM_CHANNEL_KEY = T35832.DIM_CHANNEL_KEY and T35832.DIM_PROGRAM_KEY = T36001.DIM_PROGRAM_KEY )
order by c1, c2
I was happy that I could predict what Fact table was being used, but now the results are wrong as I get a duplicate set of records for every DIM_SITE_KEY / Channel / Program combination. I decided to play a little Algebra trick. Knowing that the DIM_SITE_KEY was a numeric value, I defined the Implicit fact column as DIM_SITE_KEY / DIM_SITE_KEY which will always result in a value of 1. Now I get queries that look like:
select distinct T289.CHANNEL_NAME as c1,
T36001.PROGRAM_NAME as c2,
T35832.DIM_SITE_KEY / nullif( T35832.DIM_SITE_KEY, 0) as c3
from
DIM_PROGRAMS T36001,
DIM_CHANNELS T289,
AFactTableMappedToFactColumn T35832
where ( T289.DIM_CHANNEL_KEY = T35832.DIM_CHANNEL_KEY and T35832.DIM_PROGRAM_KEY = T36001.DIM_PROGRAM_KEY )
order by c1, c2
Since DIM_SITE_KEY / DIM_SITE_KEY is always equal to 1, I only get one set of Program / Channel combinations. I get the added bonus of knowing which set of Fact tables are going to be used to satisfy the request.Perfect Analysis, But one important note is when using implicit fact table, Always select measure( Which has some aggregation) as a implicit fact column. So that will allows the query will eliminate duplicate rows by doing a group by operation.
Other note is make sure performance is good. When we don't have a good model for fact tables, when the tables contains large set of data, make sure performance is good by doing indexes or caching to load the prompts.

Is this the right way to implement a database using SQL Server Express?
Purchase a single central server (if you don’t have one already) and house it in the Wild Wood Apartments headquarters located in San Francisco, California
Purchase and install Windows Server 2012 Datacenter onto this single central server.
Along with the Windows Server 2012 Datacenter, you will have to purchase a license called Client Access License or commonly referred to as CAL
Install SQL Server Express onto this single central server as well
You will then need to install remote desktop access to each computer in the 20 building complexes Wild Wood Apartments owns. This allows each complex manager to access SQL Server Express on their computer and input information into the database.
Is there anything that I would have to add on or include, am I missing something, or is something incorrect?
Thank youThis allows each complex manager to access SQL Server Express on their computer and input information into the database.
Yes, but application software must be developed or purchased.
Your design would work for a small scale database and application. More likely you need a pay SS product such as Standard Edition.
