I suppose keyboard mappings can do pretty much anything, but for the time being I'm using them as a sort of snippets facility almost exclusively.
So, for example, if I type def{TAB} (<em>:imap def{TAB} def ():<ESC>3ha</em>), it expands to:
def |(): # '|' represents the caret
This works as expected, but I find it annoying when VIM waits for a full command while I'm typing a word containing "def" and am not interested in expanding it.
* Is there a way to avoid this or use this function more effectively to this end?
* Is any other VIM feature better suited for this? | vim | vimtips | null | null | null | null | open | How to create short snippets in VIM?

<Grid x:Name="ParentContainer">
<ScrollViewer>
...
</ScrollViewer>
</Grid>
My goal is to get all MouseMove events on the ScrollViewer, or something reasonably close to it like the ParentContainer, *without* resorting to setting ManipulationMode="Control" on the ScrollViewer for the best possible performance.
Handling MouseMove on the ParentContainer (or the ScrollViewer) works when ManipulationMode="Control" is set on the ScrollViewer, but not when ManipulationMode="System". It sounds like to improve performance in Mango, the ScrollViewer started swallowing MouseMove events to improve performance. However, I'd expect to be able to get those handled events as follows:
ParentContainer.AddHandler(???.MouseMoveEvent, MyMouseMoveHandler, true);
In Silverlight or WPF I would expect that code to route all mouse events to MyMouseMoveHandler, even handled events. Unfortunately I can't find a static definition of MouseMoveEvent to pass to AddHandler.
Has anyone had success using AddHandler with MouseMoveEvent in WP7?
My last resort may be to add an overlay on top of the ScrollViewer with Background="Transparent" that would capture all Mouse events, but not mark them as handled and see if they propagate down to the ScrollViewer. | c# | silverlight | windows-phone-7 | event-handling | mouse | null | open | Possible to handle all MouseMove events in WP7.1?

</rdf:RDF> | java | parsing | jibx | null | null | null | open | How can I parse a spdx file using JiBX in Java
===
i am trying to parse a spdx file using JiBX in Java. I want to parse only some elements, not all the elements in the file, not in an ordered manner and some of the elements repeat. Some elements that I want to parse are: < creator >, < packageDownloadLocation > or < checksumValue >.
The problem I encountered is that after parsing, the object's properties are null. The object itself is not null.
Can you please help me?
The binding XML file is:
<binding>
<mapping name="RDF" class="com.transfer.SpdxTransferObject" ordered="false" flexible="true">
<namespace uri="http://www.w3.org/1999/02/22-rdf-syntax-ns#" prefix="rdf" default="all"/>
<namespace uri="http://usefulinc.com/ns/doap#" prefix="j.0" />
<namespace uri ="http://www.w3.org/2000/01/rdf-schema#" prefix="rdfs" />
<namespace uri="http://spdx.org/rdf/terms#" prefix="noPrefix"/>
<value name="creator" field="mCreator" get-method="getCreator" set-method="setCreator" default="none"/>
</mapping>
</binding>
The SpdxTransferObject is a simple Java bean with setters and getters:
public class SpdxTO implements Serializable
{
/** Default serial version ID */
private static final long serialVersionUID = 1L;
private String mCreator;
private String mPackageDownloadLocation;
private String mChecksumValue>;
/* getters and setters */
......
}
The Java code is:
public class ParseSpdxFile
{
/** Our logger */
private static Log sLog = LoggerFactory.create();
public static SpdxTransferObject parseFromFile(final File pFile) throws ValidationException
{
sLog.debug("Parsing the Spdx file");
SpdxTO data = null;
JiBXFileHandler handler;
try
{
handler = new JiBXFileHandler(BindingDirectory.getFactory(SpdxTransferObject.class));
data = (SpdxTransferObject) handler.loadFromXML(pFile);
}
catch (JiBXException e)
{
throw new ValidationException(e);
}
catch (Exception e)
{
throw new ValidationException(e);
}
return data;
}
}
public class JiBXFileHandler
{
private final IBindingFactory mBfact;
public JiBXFileHandler(final IBindingFactory pBfact)
{
mBfact = pBfact;
}
public Object loadFromXML(final File pFile) throws Exception
{
FileInputStream in = null;
try
{
IUnmarshallingContext uctx = mBfact.createUnmarshallingContext();
in = new FileInputStream(pFile);
return uctx.unmarshalDocument(in, null);
}
finally
{
IOUtils.closeQuietly(in);
}
}
}
The spdx file is the following:

the problem is this:
when you call the discoveryAgent's cancelInquiry method from within a synchronized block,
it hangs. it is actually supposed to call back inquiryCompleted. the code simply freezes- never enters
the inquiryCompleted method.
if the same thing is done but not from within a synchronized block - everything works. The problem is that i need the block to be synchronized so that everything in it is executed atomically in a multi-threaded app.
This is what my DiscoveryListener looks like:
public class DeviceDiscoverer implements DiscoveryListener {
private Object thisCannotBeInterruptedByOtherBlocksLikeIt=new Object();
private boolean stiiInCycle;
private DiscoveryAgent discoveryAgent;
public boolean cancel() { //called from some controller in mid discovery
//synchronized(thisCannotBeInterruptedByOtherBlocksLikeIt) //problem when this is uncommented
{
if (stillInCycle) {
//<some logic>
discoveryAgent.cancelInquiry(this);
//<more logic>
}
}
}
public void inquiryCompleted(int inquiryStatus) { //this is a callback in response to cancel or normal ending
Beeper.beep(); //this makes the phone make a sound
}
// <some irrelevant methods here. some have synchronized blocks like the one above>
}
when you run the above code, on both s40 and s60, with the synchronized statement commented out,
and call the cancel() method, the inquiryCompleted method is immediately called and you hear the beep.
BUT, if you uncomment the synchronized statement, you hear the beep on S60, but on S40 (at least on 5th edition fp1), the inquiryCompleted is never called! (when i placed the beep stmt just before calling the discoveryAgent's cancelInquiry it beeped. when i placed it after that call, it didn't get there. that's because the call does not
return until it calls inquiryCompleted and that call doesn't happen)
what is the problem? if it's a bug in the impl'n of the cancelInquiry of S40, how do i get around it?
i have to synchronize because things are done in parallel (for example my code may start an inquiry
and then, may cancel it. at the time that it is cancelled the startInquiry may be running, deviceDiscovered may be running, inquiryCompleted may be running, and of course in parallel with any of these, the incoming cancelInquiry
may be running.
i tried to separate the inquiryCompleted into another listener instance, in other words, instead of calling
discoveryAgent.cancelInquiry(this) i called discoveryAgent.cancelInquiry(anotherInstance) hoping that
the inquiryCompleted in the 'anotherInstance' would be called but no, it hangs that way as well.
any suggestions?

Beeper.beep(); //this makes the phone make a sound
}
// <some irrelevant methods here. some have synchronized blocks like the one above>
}
when you run the above code, on both s40 and s60, with the synchronized statement commented out,
and call the cancel() method, the inquiryCompleted method is immediately called and you hear the beep.
BUT, if you uncomment the synchronized statement, you hear the beep on S60, but on S40 (at least on 5th edition fp1), the inquiryCompleted is never called! (when i placed the beep stmt just before calling the discoveryAgent's cancelInquiry it beeped. when i placed it after that call, it didn't get there. that's because the call does not
return until it calls inquiryCompleted and that call doesn't happen)
what is the problem? if it's a bug in the impl'n of the cancelInquiry of S40, how do i get around it?
i have to synchronize because things are done in parallel (for example my code may start an inquiry
and then, may cancel it. at the time that it is cancelled the startInquiry may be running, deviceDiscovered may be running, inquiryCompleted may be running, and of course in parallel with any of these, the incoming cancelInquiry
may be running.
i tried to separate the inquiryCompleted into another listener instance, in other words, instead of calling
discoveryAgent.cancelInquiry(this) i called discoveryAgent.cancelInquiry(anotherInstance) hoping that
the inquiryCompleted in the 'anotherInstance' would be called but no, it hangs that way as well.
any suggestions?
thanks in advance | 0 |

It works as expected with one exception. If I start the interpreter and press Ctrl-Z + Enter, I get:

That's correct. But if I start the interpreter and press Ctrl-C followed by Ctrl-Z + Enter I get:
>>>

And it hangs and I can't use the interpreter anymore. However, if I press Ctrl-C again, the REPL unblocks. I searched a lot and I can't figure out the reason of it. Can anyone explain me?

Please suggest me any solution regarding the same.
Thanks in advance. | android | cwac-endless | null | null | null | 06/13/2012 00:52:34 | not a real question | Facing an issue with Endlessadapter in android
===
I have a problem in implementing the Endlessadapter in my project. I have integrated the same in the project working as, it is downloading data in bunch (10 data) continuously in the background instead as it should download data only when I scrolled the list till the last. Due to the above problem sometimes my app returns OutOfMemoryException, which is not acceptable.
**My Code for EndlessAdapter implementation:**
**setAdapter in listView:**

but haven't really found a good process for product development, utilizing customer feedback. The issue is how does one get to rapid, agile development when customers don't speak tech. Right now we have customer support teams vet all support messages via zendesk, and use uservoice for feature requests, to best support our customers. BUT, things aren't ubber fast and I don't feel like we're giving people the best customer experience (maybe I expect too much after working with Nordstrom). The Question is:
> What process can one use to respond to customers leaving them with a great experience, and get their bugs, recommendations, and product-our solution related issues worked out to the best of our abilities? Ideally, this means we're understanding the issues to an actionable level within a few minute phone call/email with the customer, getting ?time-tables? from developers on features and fixes, and organizing all of this madness.
I'm wondering if anyone has really effective work-flows they use or have used. Thanks!! | project-management | workflow | agile | productivity | null | 08/24/2011 21:49:13 | not constructive | agile dev for customers who don't speak tech - best practices?

In many ways I enjoy Scrum. We have relatively short sprints (2 weeks). I like the Burndown Chart to track the teams progress, I like the Feature Board so I always know what I should be doing next. It feels good taking down a feature's card from the board, completing it and then putting it in the burn down pile.
However, we are now entering in our 18th Sprint release cycle and I'm starting to feel a little burnt out. It isn't that I don't like job or my co-workers, it is just that these sprints are... well, sprints. From start to finish I literally feel like I'm racing against the clock to maintain our development velocity. When we are done with the sprint we spend one day planning the next sprints feature set and estimates and then off we go again.
For people who work in a mature Agile/Scrum development process, is this normal? Or are we missing something? Sometimes I just feel like I need some unassigned, untracked time to get done some minor things, to clear my head and to fix some trivial things that aren't normally included in a sprint. | scrum | agile | null | null | null | 12/12/2011 17:36:09 | not constructive | Does anyone else get worn out using Scrum, finishing sprint after sprint?

I have a background that I'm actively drawing (I could probably be smart and draw it once and just scale it, but this shows the problem just as well).
You can use the mouse wheel to zoom in and out on the image.
The idea is to do a "google map" zoom where it zooms under the mouse pointer. What I've noticed is that it doesn't seem to actuall behave until the image is big enough to use both scroll bars. Until then, you get the image simply getting bigger, but locked to the origin.
The "correct" behavior should be that the viewposition is moved, even though the scrollbars aren't yet being utilized by an oversized image.
I'm not sure how to get around this (or if this is correct and expected) without drawing a much larger background behind the image so it more than fills the viewport.
It "jumps" after one or the other scroll bars engages due to (I think) the same issue.
Thoughts?

I was hoping I could get some help here. I have an application I'm building that is sort of a hybrid. It's probably a weird way to do it, but I want to have MVC organization, with the look and feel of the website it's going into.
Here's a little background:
- I'm not using any frameworks
- The application is structured as such:
/MyLibrary
-/MyApplication
--/controllers
---/<controller files here>
--/models
---/<model files here>
--/views
---/<view files here>
-/Filesystem (a library I have for myself for using the file system)
-/OtherDependenciesForMyApplication
- My website is structured as such:
/MyWebsiteFolder
-/include
-/scripts
-/webroot
--/index.php
--/<other folders and files>
--/myapplication
---/<this is where I would like to go for my application to be accessed>
I am sort of developing my views to be part of the page that the website displays. For example, myview.php will contain the content that will be displayed. It will be wrapped by /MyWebsiteFolder/webroot/myapplication/index.php. So, the application itself isn't made to be standalone. It's made to work off of the website's authentication system and use the website's CSS.
What suggestions do you have for me for deploying my application in this manner, while keeping my Git repositories for the website and the application separate.
If you really, really have nothing to say to help me with this specific problem, please suggest another way to do it that would use the website's authentication, get me the look and feel of being in the website, without recreating the entire website's styles in the application.
