In MySQL you can use the (roughly equivalent) MATCH function in the ORDER BY section, but I haven't found any equivalence in MSSQL.
From the [MySQL docs][1]:
> For each row in the table, MATCH() returns a relevance value; that is, a similarity measure between the search string and the text in that row in the columns named in the MATCH() list.
So for example you could order by the number of votes, then this relevance, and finally by a creation date. Is this something that can be done, or am I stuck with just returning the matching values and not having this ordering ability?

How do I check that it's working? I'm using JBoss 4.2.2.GA.
From the Hibernate documentation, it seems that I need to enable the cache and specify a cache provider in *persistence.xml*, like:
<property name="hibernate.cache.use_second_level_cache"
value="true" />
<property name="hibernate.cache.provider_class"
value="org.hibernate.cache.HashtableCacheProvider" />
What else is required? Do I need to add *@Cache* annotations to my JPA entities?
How can I tell if the cache is working? I have tried accessing cache statistics after running a Query, but *Statistics.getSecondLevelCacheStatistics* returns null, perhaps because I don't know what 'region' name to use.

git log $(git merge-base HEAD branch)..branch
The documentation for [git-diff](http://www.kernel.org/pub/software/scm/git/docs/git-diff.html) indicates that "git diff A...B" is equivalent to "git diff $(git-merge-base A B) B". On the other hand, the documentation for [git-rev-parse](http://www.kernel.org/pub/software/scm/git/docs/git-rev-parse.html) indicates that "r1...r2" is defined as "r1 r2 --not $(git merge-base --all r1 r2)". Why are these different? Note that "git diff HEAD...branch" gives me the diffs I want, but the corresponding git log command gives me more than what I want.

However, more often than not, we're not able to get a full listing of available SMB volumes using the tool. We've got a good benchmark in that we can see the full listing the Apple Finder gets, and the majority of the time, our listing is not matching up, usually missing servers.
We're tried a number ways of executing the command, but haven't yet found anything that brings us back a complete listing.
nmblookup -M -- -
nmblookup '*'
etc
Does anyone know what we could be doing wrong, or know of a better way to query for SMB volumes available on local subnets?
Many thanks

Expression<Func<T, bool>>
So the two that I want to compose are essentially delegates on a parameter (of type T) that both return a boolean. The result I would like composed would be the logical evaluation of the booleans. I would probably implement it as an extension method so my syntax would be something like:
Expression<Func<User, bool>> expression1 = t => t.Name == "steve";
Expression<Func<User, bool>> expression2 = t => t.Age == 28;
Expression<Func<User, bool>> composedExpression = expression1.And(expression2);
And later on in my code I want to evaluate the composed expression
var user = new User();
bool evaluated = composedExpression.Compile().Invoke(user);
I have poked around with a few different ideas but I fear that it is more complex than I had hoped. How is this done?

1. You have a fairly "hands off" customer, who really doesn't want to get too involved in the decision making despite your best efforts.
2. An experienced development team spend hours discussing the pros and cons of a particular approach to a problem and come up with an elegant solution which avoids the pitfalls of the more obvious approaches.
3. The customer casually mentions after a quick glance that they want it changed. They have no understanding of all the usability / consistency issues you were trying to avoid in your very carefully thought out approach.
4. Despite explanations, customer isn't interested, they just want it changed.
5. You sigh and do what they ask, knowing full well what will happen next...
6. 3 weeks later, customer says it isn't working well this way, could you change it? You suggest again your original solution, and they seize on it with enthusiasm. They invariably seem to have had a form of selective amnesia and blocked out their role in messing this up in the first place.
I'm sure many of you have gone through this. The thing which gets me is always when we know the time and effort that reasonably bright and able people have put in to really understanding the problem and trying to come up with a good solution. The frustration comes in contrasting this with the knowledge that the customer's choice is made in 3 minutes in a casual glance (or worse, by their managers who often don't even know what the project is really about). The icing on the cake is that it's usually made very late in the day.
I know that the agile methodologies are designed to solve exactly this kind of problem, but it requires a level of customer buy in that certain types of customers (people spending other peoples money usually) are just not willing to give.
Anyone any clever insight into how you deal with this?
EDIT: Oops - by the way, I'm not talking about any current or recent customer in this. It's purely hypothetical...

I am currently using QTKit to do this but unfortunately when QTKit exports to m4a format the metadata is all stripped out (this has been confirmed as a bug by Apple) see [sample code](http://files.shinydevelopment.com/audiojoiner.zip). I think this rules QTKit out for this job, but would be happy to be proven wrong as it is a really neat API for it if it worked.
So, I am looking for a way to concatenate audio files (input format does not really matter as I can do conversion) into an m4a file with chapters metadata.
As an alternative to code, I am open to the idea of using an existing command line tool to accomplish this as long as it is redistributable as part of another application.
Any ideas? | osx | objectivec | cocoa | audio | quicktime | null | open | Creating MP4/M4A files with Chapter marks

_"the table must contain data when the index is created. If you create the temporary table and create the index on an empty table, Adaptive Server does not create column statistics such as histograms and densities. If you insert data rows after creating the index, the optimizer has incomplete statistics."_
but recently a colleague mentioned that if I create the temp table and indices in a different stored procedure to the one which actually uses the temporary table, then Adaptive Server optimiser _will_ be able to make use of them.
On the whole, I'm not a big fan of wrapper procedures that add little value, so I've not actually got around to testing this, but I thought I'd put the question out there, to see if anyone had any other approaches or advice?

If possible, I'd also like the tool to generate varying levels of complex pages so that I can stress test a set of DOMs. This isn't a necessity - if I need to do so, I can write one myself; however, I'd figure I'd poll the community first to see if something already exists.

This scares us a little, as it's possible that this merge, while not producing any compile errors, could at least introduce some logic errors that may not be easily detected.
Very simple example: I'm working within a C# method changing some logic in the latter-part of the method, and somebody else changes the value that a variable gets initialised to at the start of the method. The other person's change isn't in the lines of code that I'm working on so there won't be a conflict; but it's possible to dramatically change the output of the method.
What we were hoping the situation would be is that if a merge needs to occur, then the two files would be shown and at least a simple accept/reject change option be presented, so that at least we're aware that something has changed and are given the option to see if it impacts our code.
Is there a way to do this with Subversion/TortoiseSVN? Or are we stuck in our present working ways too much and should just let it do it's thing...

| java | windows | swing | null | null | null | open | Why does windows XP minimize my swing full screen window on my second screen ?
===
In the application I'm developping (in Java/swing), I have to show a full screen window on the *second* screen of the user.
I did this using a code similar to the one you'll find below...
Be, as soon as I click in a window opened by windows explorer, or as soon as I open windows explorer (i'm using windows XP), the full screen window is minimized...
Do you know any way or workaround to fix this problem, or is there something important I did not understand with full screen windows?
Thanks for the help,

However, if you link directly to a SWF file it will open in the browser window and without looking in the address bar you can't tell that it wasn't embedded in HTML with the size set to 100% width and height.
Considering the overhead of the HTML, CSS and JavaScript needed to embed a Flash or Flex application filling 100% of the browser window, what are the downsides of linking directly to the SWF file instead? What are the upsides?
I can think of one upside and three downsides: you don't need the 100+ lines of HTML, JavaScript and CSS that are otherwise required, but you have no plugin detection, no version checking and you loose your best SEO option (progressive enhancement). | flex | flash | embed | null | null | null | open | Linking directly to a SWF, what are the downsides?

WPF, WF, Silverlight, Powershell, SSIS, SSDS, EF, LINQ, WCF, Data Services, XAML, Asp.Net AJAX, Asp.Net MVC blah blah..
Since I am in a Technical role (like most of you), fundamental knowledge or just familiarity is not enough.
I need to dig a little deeper into all the new technologies, try out prototypes and check if everything fits together, considering lots of other critical factors like Business, technology maturity, environment and people.
Not to mention comparison with other competing technologies for convincing my team.
In some cases, you have to be strongly aware of concepts like REST and how it is different from SOAP. In other cases, you have to get your hands dirty for workflow solutions using WF.
Again, one fine day you find that stuffs like WinFS is completely erased from the map and getting evolved into something different.
One of the earliest warning I got for not updating my skills was when I was a bit slow to adopt SQL 2005. Because of that, I am still having a hard time catching up with SQL 2008.
In another scenario, I was involved with .Net 2.0 at a very early stage and was able to adjust faster with .Net 3.0/3.5. Even the 3.5 SP1 has a bunch of new features.
I admit I love gathering knowledge but was wondering if there are efficient ways of managing and absorbing all this information without affecting normal work schedule.
My question is how do you all manage this information overload? One thing I have done is setting a filter. I loved reading hardware review sites as a hobby but now totally cut them off from my list.

I'm looking at improving the performance of some SQL, currently CTEs are being used and referenced multiple times in the script. Would I get improvements over using a table variable instead? (Can't use a temporary table as the code is within functions) | 0 |

What I am looking for is a tool that can log on to a web site and test a few links and the performance. At least one of the links will access another web-based product using single sign on. I would set it up to check the site every 5 to 15 minutes, record how long each page takes to render in the browser, and send an alert if anything goes wrong. Have you used anything like that that worked well (or very poorly)? | performance | website-monitoring | null | null | null | null | open | Website performance monitoring tools

I'd recently heard about a challenge amazon had posted to the world to come up with a better recommendation engine for their system.
The winner apparently produced the best algorithm by limiting the amount of information to that was being fed to it.
As a first rule of thumb I guess... "**More information is not necessarily better when it comes to fuzzy algorithms."**
I know's it's subjective, but ultimately it's a measurable thing (clicks in response to recommendations).
Since most of us are dealing with the web these days and search can be considered a form of recommendation... I suspect I'm not the only one who'd appreciate other peoples ideas on this.
In a nutshell, **"What is the best way to build a recommendation ?"**

No need for extra features like traffic spying, I'm just interested by bandwidth.
I already know Wireshark (which is great), but what I'm looking for is more something like TcpView (great tool from Sysinternals) with current bandwidth indication.
PS: I'm interested by Windows tools only | windows | networking | null | null | null | null | open | Best tool to monitor network connection bandwidth
