MacBook Pro scrolling/zooming flickers

2009-04-21T16:36:00.002Z

Got a new 2.66GHz MacBook Pro a few days ago and yesterday the scrolling/zooming flickers kicked in. I found this discussion but no help there yet.

Looks like a chip bug with the NVIDIA graphics card. Good thing there are two of them in the machine...best would have been if one was from another manufacturer ;)

I really had enough when trying to zoom with the trackpad in iPhoto so I decided to try to switch to the other graphics display card. That was simple. Seems to work, at least for now, but the issue seems to build up over time.

I'll add comments here to follow this through.

WebObjects application launching as MainBundle.woa

2009-03-26T12:59:00.002Z

For some unknown reason a couple of WebObjects applications were not not launching as the APPLICATION_NAME.woa but as MainBundle.woa and totally unusable as such.

When launching from Eclipse I got an error on locating Info.plist in JavaDTWGeneration.framework, JavaEOGeneration.framework and JavaEOProject.framework that was causing the problem.

Reinstalled Webobjects 5.4.3 and everything when back to normal.

Using JVC GZ-HD7 Everio with MAC OS X

2009-01-22T16:40:00.006Z

Converting TOD FHD files from JVC Everio on Mac OS X
If you wan't to edit you Full HD videos from your Everio in iMovie you'll have to convert the videos to work on the mac.

You'll need to download and install ffmpegx and connect your JCV Everio via USB and locate the TOD file(s).

In ffmpegx click Open and choose the TOD file

Set the destination file in the Save As

Under Target format select MOV

Under Video set the bitrate to 28000

Under Audio it might be a good idea to match the bitrate too

Click Encode and just wait =)

Evario manual
The manual for the Everio can be found, as most manuals, at retrevo.com, but you have to sign up. For those how don't wan't to use this great service the manuals can be accessed on this folder at box.net.

Importing straigt into iMovie
You can set the record quality down to 1440( down from 1920 ) and then you can read straight from the Everio into iMovie via FireWire cable.
When you need to import into iMovie just follow the instructions in this video:

2008-07-01T11:29:00.002Z

Don't forget the little magic in

Unlimited email address with your Gmail

2008-07-01T08:57:00.003Z

You can send yourself emails with the plus sign(+) after your gmail address and then any text you want after the plus sign and it will show up in your inbox. Ex. if your gmail address is rass@gmail.com you can send yourself and email to rass+gat@gmail.com.

This can be quite handy when giving your email to "unknown" websites and also with filters you can organize your email pretty neatly.

Note that not all website forms allow you enter the + sign, in those cases you can also replace gmail.com googlemail.com, e.x. rass@googlemail.com is delivered to rass@gmail.com ;)

CallableStatement date&time parameter

2008-05-07T16:03:00.002Z

The caret synbol( ^ ) in bindings

The caret symbol( ^ ) indicates that the value should be taken from the parent component.

Getting resources from Unit Tests

2008-03-11T09:28:00.002Z

Since Unit Tests are run from the command line( or Ant ) access to Resources of a WebObjects project are no good with ResourceManager. Simple functions to get resources based on the filesystem:


/**
 * Returns a path to a resource filename in a folder(s) under the root folder
 * */
private String resourceLocationString( String filename, String folder ) {
    String urlToFile = getClass().getResource( "/" ).toString();
    urlToFile = urlToFile.replace( "bin/", "" );
    urlToFile = urlToFile.replace( "file:", "" ); // now we should be at the projects root directory
    urlToFile = urlToFile.concat( folder + "/" + filename );
    return urlToFile;
}

/**
 * Returns data for pdf file
 * */
private byte[] bytesForPDFResource( String urlToFile ) throws FileNotFoundException, IOException {
    FileInputStream in = new FileInputStream( urlToFile );
    byte[] data = new byte[in.available()];
    in.read(data);
    return data;
}

Write data to a file in the filesystem

2008-03-11T09:19:00.002Z


FileOutputStream fs = new FileOutputStream( ABSOLUTE_PATH_TO_FILE );
fs.write( SOME_DATA );
fs.close();

Executing SQL

2008-01-18T11:50:00.000Z

Need to call simple SQL commands, like getting the next primary key by calling a sequence:


NSArray rawRows = EOUtilities.rawRowsForSQL( EDITING_CONTEXT, MODEL_NAME, SQL_STRING, NSArray.EmptyArray );
NSDictionary rowWithPK = (NSDictionary)rawRows.objectAtIndex( 0);
Object maxPK = rowWithPK.objectForKey( "NR" );

Pro Tools EZDrummer plug in output

2008-01-16T10:33:00.000Z

Installined EZDrummer and created a stereo Instrument track in Pro Tools LE 7.1.1 but didn't get no output from the track. I had other audio tracks that worked fine, and creating a stereo audio track got the output from EZDrummer but you need the Instrument track to drop the midi loops onto. After about 2 hours of hacking Pro Tools, reading forms, reading manuals and other desperate measures I noticed that the volume on my Instrument track was turned down and the only thing I needed to do was to crank it up. Since this is not the case with audio tracks tracks I failed to check this...that won't happen again ;)

Symbolic link

2007-11-22T10:17:00.002Z

Keep forgetting how to add a framework:

cd /Libarary/Frameworks

Then add your framework like this example with EkjaFramework in my Developer workspace:

ln -s /Developer/workspace/EkjaFramework/dist/EkjaFramework.framework/ EkjaFramework.framework

WOCheckBox binding

2007-11-15T11:07:00.001Z

SQL Server 2000 IDENTITY_INSERT

2007-10-18T10:53:00.000Z

SQL Server has got identity for primary keys( see this article ) that was preventing me from inserting into a table with EO.

To get by this you can just set the identity insert to on with:

EOUtilities.rawRowsForSQL( ec, modleName, "SET IDENTITY_INSERT tableName ON", NSArray.EmptyArray );

Note that you might need to get the new primary key( identity ) yourself, ex.:


NSArray rawRows = EOUtilities.rawRowsForSQL( ec, modleName, "SELECT MAX(idenityColumnName) as NR FROM tableName", NSArray.EmptyArray );
NSDictionary rowWithPK = (NSDictionary)rawRows.objectAtIndex(0);
Object maxPK = rowWithPK.objectForKey("NR");
int primaryKey = (new Integer(maxPK.toString())).intValue();

Right clicking a message will bring it up in a floating container, pretty neat.

Get parameter from URL

Creating a cover method for the parameter with:

will always give me what I want ;)

Long WO

WOImage with data binding

2007-09-27T08:16:00.000Z

A WOImage with data bound to NSData( read from DB ) was not showing up on print.
Binding the "key" to a unique identifier for every image did the trick.
Hugi pointed this out to me, he had run into it some years ago, seems the NSData is only kept for a short period of time in the cache and setting the key will extend it's lifetime there.

UNIX find pattern

e.x. grep -c -r logi *
search all files/folders for "logi"

...havn't tried the "find" ;)

Unique ID for element

2007-09-20T13:51:00.000Z

When working with JavaScript I often need a unique ID for the current component I'm woking with:


ERXStringUtilities.replaceStringByStringInString( ".", "_", context().elementID().toString() );

Get previous page name

2007-09-20T10:24:00.000Z

I wanted to enable the user to go back to the previous page without using a WOActionResults to set the name of the component calling the nextPage. WOContext has a method called page that did this for me with ease ;)


String previousPage = context().page().name();

WOFileUpload

2007-09-19T16:42:00.001Z

Created a WOFileUpload and connected the inputStream attribute to an input stream but nothing worked, kept getting a NP untill I connected FilePath to a String variable, then the WOFileUpload worked like charm( annoying charm that took too much of my time to figure out ).

Overwriting valueForKeyPath

2007-09-19T16:25:00.000Z

I need to access a localalized strings file for the right language and I don't like the Localizer method.
I wanted to access it through Application and in the WOD files by simply adding "application.@ls.MY_STRING_TO_GET_FROM_LOCALIZED_STRING".

Added the following to Application.java:


   public Object valueForKeyPath( String keypath ) {

        // Catch all keypaths starting with ls and do whatever you want with it
        if( keypath.startsWith( "@ls" ) )
            return localizedStringForKey( keypath.substring( 4, keypath.length() ) );

        return super.valueForKeyPath( keypath );
    }

    public String localizedStringForKey( String key ) {
        return WOApplication.application().resourceManager().stringForKey( key, "localizedStrings", "!!LOCALIZED_STRING_NOT_FOUND!!", "app", languages() );
    }
