I've shown it to a few people, and they are all extremely enthusiastic, so I've been considering actually finishing it up, adding some bells and whistles, and selling it.
One key feature of the product is a certain combination of user interface and functionality that I haven't ever seen before, and which, in my humble opinion, is both very useful and very cool - it makes (I hope) a very unique and compelling selling point, particularly to a certain demographic.
I'm not sure if or how I should seek a patent on this feature before I release it. I have no budget for this, only my personal time and money, so spending thousands of dollars on a lawyer probably isn't an option.
To be honest, I don't really care about having a monopoly on the the idea... if others imitate me, that will prove I've had enough success myself that I'm probably going to be happy. If I could pay off half my student loans, I'd consider that a smashing success. I'm somewhat libertarian, philosophically, and tend to regard patents as a rather necessary evil.
On the other hand, part of me says that I shouldn't close doors on myself, and if, by some miracle, my product really does become popular and I end up starting a company based off of it, I'm not going to want to limit my success. This scenario is unlikely, I know, but still, I'm not sure if I should consider this or not. And an even bigger concern... having a patent might provide some negotiating power or legal backing if I should draw attention from a certain huge, punitive software company who decides they want what I have.
Additionally, there is the logical possibility that someone else has already patented a similar idea. If that is the case, would I be better off not even looking for it? I know that damages are much, much higher for willful infringement, but much less if I did due diligence in trying to find existing patents. I guess it would at least give me a position to work from, and adjust it so as not to actually infringe, before I release. But is this even possible to do myself, or do I need to hire an expensive lawyer in order to have any confidence in my findings? | legal | business | null | null | null | 05/06/2012 23:06:32 | off topic | When/if to seek a patent?

i'm trying to duplicate a datepicker by cloning the div that is containing it.
<a href="#" id="dupMe">click</a>
<div id="template">
input-text <input type="text" value="text1" id="txt" />
date time picker <input type="text" id="example" value="(add date)" />
</div>
to initialize the datepicker, according to the [jQuery UI documentation][1] I only have to do $('#example').datepicker(); and it does work but only on the first datepicker that is created.
the code to duplicate the div is the following
$("a#dupMe").click(function(event){
event.preventDefault();
i++;
var a = $("#template").clone(true).insertBefore("#template").hide().fadeIn(1000);
a.find("input#txt").attr('value', i);
a.find("input#example").datepicker();
});
the strangest thing is that on the document.ready i have
$('#template #example').datepicker();
$("#template #txt").click(function() { alert($(this).val()); });
and if i click on the #txt it always works.

I've been working today in modifying ASP.NET's Membership to add a level of indirection. Basically, ASP.NET's Membership supports Users and Roles, leaving all authorization rules to be based on whether a user belongs to a Role or not.
What I need to do is add the concept of Function, where a user will belong to a role (or roles) and the role will have one or more functions associated with them, allowing us to authorize a specific action based on if the user belongs to a role which has a function assigned.
Having said that, my problem has nothing to do with it, it's a generic class design issue.
I want to provide an abstract method in my base RoleProvider class to create the function (and persist it), but I want to make it optional to save a description for that function, so I need to create my CreateFunction method with an overload, one signature accepting the name, and the other accepting the name and the description.
I can think of the following scenarios:
1. Create both signatures with the abstract modifier. This has the problem that the implementer may not respect the best practice that says that one overload should call the other one with the parameters normalized, and the logic should only be in the final one (the one with all the parameters). Besides, it's not nice to require both methods to be implemented by the developer.
2. Create the first like virtual, and the second like abstract. Call the second from the first, allow the implementer to override the behavior. It has the same problem, the implementer could make "bad decisions" when overriding it.
3. Same as before, but do not allow the first to be overriden (remove the virtual modifier). The problem here is that the implementer has to be aware that the method could be called with a null description and has to handle that situation.
I think the best option is the third one...
How is this scenario handled in general? When you design an abstract class and it contains overloaded methods. It isn't that uncommon I think...

I've also helped bring in some visibility to the development cycle of a major product that has been lagging for over a year. People are loving it!
However, my coworker (the only other dev here for now) is not into it. She prefers to close her door and focus on her work and be left alone. Me?

set FILENAME=%~f1
sed 's/Some Pattern/%FILENAME%/' inputfile
(Note: %~f1 - expands %1 to a Fully qualified path name - C:\utils\MyFile.txt)
I found that the backslashes in %FILENAME% were just escaping the next letter.
How can I double them up so that they are escaped?

import mx.core.Application;
import mx.events.FlexEvent;
import flexunit.framework.TestCase;
public class CustomComponentTest extends TestCase {
private var component:CustomComponent;
public function testSomeAspect() : void {
component = new CustomComponent();
// set some properties...
component.addEventListener(FlexEvent.CREATION_COMPLETE,
addAsync(verifySomeAspect, 5000));
component.height = 0;
component.width = 0;
Application.application.addChild(component);
}
public function verifySomeAspect(event:FlexEvent) : void {
// Assert some things about component...
}
override public function tearDown() : void {
try {
if (component) {
Application.application.removeChild(component);
component = null;
}
} catch (e:Error) {
// ok to ignore
}
}
Basically, you need to make sure the component has been fully initialized before you can reliably verify anything about it, and in Flex this happens asynchronously after it has been added to the display list. So you need to setup a callback (using FlexUnit's addAsync function) to be notified when that's happened.
Lately i've been just manually calling the methods that the runtime would call for you in the necessary places, so now my tests tend to look more like this:
import flexunit.framework.TestCase;
public class CustomComponentTest extends TestCase {
public function testSomeAspect() : void {
var component:CustomComponent = new CustomComponent();
component.initialize();
// set some properties...
component.validateProperties();
// Assert some things about component...
}
This is much easier to follow, but it kinda feels like I'm cheating a little either way. The first case is slamming it into the current Application (which would be the unit test runner shell app), and the latter isn't a "real" environment.
I was wondering how other people would handle this sort of situation? | unit-testing | flex | null | null | null | null | open | FlexUnit component testing patterns: use addAsync or manually initialize?

My production database is several megs in size and growing. Every time the database replication stops and the databases inevitably begin to slide out of sync i cringe. My last resync from dump took almost 4 hours roundtrip!
As always, even after sync, I run into this kind of show-stopping error":
Error 'Duplicate entry '252440' for key 1' on query.
I would love it if there was some way to closely monitor whats going on and perhaps let the software deal with it. I'm even all ears for service companies which may help me monitor my data better. Or an alternate way to mirror altogether.
**Edit**: going through my previous questions i found [this][5] which helps tremendously. I'm still all ears on the monitoring solution.

My production database is several megs in size and growing. Every time the database replication stops and the databases inevitably begin to slide out of sync i cringe. My last resync from dump took almost 4 hours roundtrip!
As always, even after sync, I run into this kind of show-stopping error":
Error 'Duplicate entry '252440' for key 1' on query.
I would love it if there was some way to closely monitor whats going on and perhaps let the software deal with it. I'm even all ears for service companies which may help me monitor my data better. Or an alternate way to mirror altogether.
**Edit**: going through my previous questions i found [this][5] which helps tremendously. I'm still all ears on the monitoring solution.
cheers,

Workaround? | I'm using a native DLL (FastImage.dll) in a C# ASP.NET Web Service that sometimes locks (can't delete it---says access denied); this requires stopping IIS to delete the DLL. The inability to delete this DLL in the bin folder of my published Web Service prevents me from publishing successfully (even though it thinks it published successfully!), which makes development and fixing the bug difficult (especially when it just happily runs old code since my changes may not be reflected on the server!).

This is a mod_perl implementation, so an instance of a class can be quite old between times that it is accessed.
From the man pages I found two options:
Music::DBI->clear_object_index();
And:
Music::Artist->purge_object_index_every(2000);
Now, when I add clear_object_index() to the DESTROY method, it seems to run, but doesn't actually empty the cache. I am able to manually change the database, re-run the request, and it is still the old version.
purge_object_index_every says that it clears the index every n requests. Setting this to "1" or "0", seems to clear the index... sometimes. I'd expect one of those two to work, but for some reason it doesn't do it every time. More like 1 in 5 times.
