Removing Latex Tags in a Word Document

We can use the regexp feature of the find/replace tool in Word.

Search for:

\\code\{(*)\}

Where:

• \ is the escape char (thus the \\ for detecting a Latex tag)
• * means “everything”
• ( ) creates a logical entity that you can re-use in the replace field.

and replace by:

\1

which refers to the entity we created by using ().

Changing the Default Java Vendor (or Version) in Ubuntu

Run sudo update-java-alternatives -l to see the current configuration and possibilities.

Run sudo update-java-alternatives -s XXXX to set the XXX java version as default.
For Sun Java 6 this would be sudo update-java-alternatives -s java-6-sun

Run java -version to ensure that the correct version is being called.

Doing PUT DELETE and Other Niceties with GWT

You probably are REST lovers like I personally am.

Thus you were probably quite frustrated when seeing that a GWT (Google Web Toolkit) client cannot send other requests than POST or GET.
Well here is the solution:

public class RequestBuilderForAnyHTTPMethodTypeExample extends RequestBuilder {

/**
* Constructor that allows a developer to override the HTTP method
* restrictions imposed by the RequestBuilder class. Note if you override the
* RequestBuilder's HTTP method restrictions in this manner, your application
* may not work correctly on Safari browsers.
*
* @param httpMethod any non-null, non-empty string is considered valid
* @param url any non-null, non-empty string is considered valid
*
* @throws IllegalArgumentException if httpMethod or url are empty
* @throws NullPointerException if httpMethod or url are null
*/
public RequestBuilderForAnyHTTPMethodTypeExample(String httpMethod, String url) {
super(httpMethod, url);
}


i.e. simply subclass the RequestBuilder

Distributing a Visual Studio C++ Exe That Does not Need the Windows .NET Framework

If like me you export your Visual Studio (2008) .NET C++ project as an EXE, copy it on another machine and get: “This application has failed to start because the application configuration is incorrect”. Then it might be because the target machine is actually missing the Microsoft .NET Framework.

Since I did not really felt like asking all the future users of my app to install the .NET framework, I started looking for a way of embedding these libs in my final app.

While it is apparently not possible to do so without requiring a special (commercial) tool, there is a workaround that worked for me. By forcing the C/C++ to by statically linked the framework functions actually are embedded into the EXE (which, btw, gets much bigger then).

To do so (in Visual Studio .NET 2008 C/C++, Express) do:
Property Page -> Configuration Properties -> C/C++ -> Code Generation then “Runtime Library” should be set to an “non-dll” option such as Multi-threaded (for the release target) or Multi-threaded Debug (to debug your app).

Here we go!

JSON and the Quoted Strings

“Bug” number two for today is a little more tricky.

I was retrieving a JSON object in the GWT (Google Web Toolkit) and putting its Java representation in a HashMap. The only problem is that I could never find it again by referring to its key which I also extracted from JSON object. Here is why:

currentCons.get("URI").isString().toString()

Is actually not returning the String representation of a JSONString object but the quoted representation of that String: e.g. “key” and not key. It was in the API but it took me a while to figure it out…

The solution is:

currentCons.get("URI").isString().stringValue();

Which gets what I wanted, i.e. the String representation without the quotes.

Iterators and Deadlocks: How Not to Use Iterators!

Two nice little bugs today which sums up most of my day

How not to use iterators:


while(views.iterator().hasNext()) {
View currentView = (View) views.iterator.next();
currentView.update();
}


Bing that basically crashed my Firefox (this is part of a GWT app) when running it as well as my Netbeans / GWT debugger. Notice that Firefox was so good to tell me that apparently the script I was running in a weird manner.

And it was indeed in an endless loop as you can guess: invoking the iterator() method returns a new Iterator object every time (which it is supposed to do, I’m the dumb one in that story). Thus, I was basically getting the same “next()” object every time and hasNext() was thus always true

Anyway that fixes it:


Iterator viewsIt = views.iterator();
while(viewsIt.hasNext()) {
View currentView = (View) viewsIt.next();
currentView.update();
}


Ok that was a trivial one, but actually so trivial that I just felt like shaming me a little more and publishing it here
