Don't use a base class unless you know what it means, and that it applies in this case. If it applies, use it, otherwise, use interfaces. But note the answer about small interfaces.

I have rewrote the original linq statement to where I now use a join instead of the Contains, but would still like to know if there is a way around this issue. |
The more I look at it, and after running more tests, I'm thinking the bug may be in the Sql Server Query Visualizer plugin for Visual Studio, not actually in Linq to SQL itself. So it is not nearly as bad a situation as I thought - the query will return the right results, but you can't trust what the Visualizer is show... |
<p>The issue stems from the fact that you can't deserialize an interface but need to instantiate a concrete class.</p>
<p>The XmlInclude attribute can be used to tell the serializer what concrete classes implement the interface.</p>

Just a minor point to add to this thread... there is no alt tag or title tag. The alt attribute is for images, but all other elements on a page can have a title attribute, which is the best choice for cross browser compatibility.

How to build large/busy RSS feed |

I've been playing with RSS feeds this week, and for my next trick I want to build one for our internal application log.

I want to create an RSS feed off of this table, but I'm not sure how to handle the volume- ... |
I think this would be extremly useful. Depending on the size of a project team members come and go. And a wiki is a good tool to keep the history and the "spirit" of a project available to new team members. I did that in many projects, and though the projects were already finished, all the informations are available.

The other classic integration would be your source code repository, e.g. svn, or cvs. [trac][1] is an existing product that does exactly this - it combines a wiki, custom bug tracker, and integrates nicely with svn.
[1]: http://trac.edgewall.org/ |
Of course it's useful, there are already ready-made packages for this kind of project-overviews (like http://trac.edgewall.org/).
If possible, I'd integrate any existing CI-engine into the wiki, so that you have a complete overview over the current progress and your project's health.

Since ID is not sequential, I assume you have a unique index on ThingID and PriceDateTime so only one price can be the most recent for a given item.

[Dictionary Class](http://msdn.microsoft.com/en-us/library/xfhwa508.aspx) is exactly what you want, correct.
You can declare the field directly as Dictionary<string, string>, instead of IDictionary, but that's up to you. |
There is a KeyValuePair<S,T> built-in type. As a matter of fact, this is what the IDictionary is giving you access to when you iterate in it.
Also, this structure is hardly a tree, finding a more representative name might be a good exercise. |
I like the versatility of jEdit (http://www.jedit.org), its got a lot of plugins, crossplatform and has also stuff like block selection which I use all the time.
The downside is, because it is written in java, it is not the fastest one. |
One possible thing you could do is use the Dictionary object straight out of the box and then just extend it with your own modifications:
public class TokenTree : Dictionary<string, string>
{
public IDictionary<string, string> SubPairs;
}
This gives you the advantage of not having to enforc... |
@[Jay Mooney](http://stackoverflow.com/users/733/jay-mooney): A generic Dictionary class in .NET is actually a hash table, just with fixed types.

I believe so. Since the function pointer uses the signature to identify itself, the base/derived behavior would rely on whatever object you called it on. |
Are you trying to assign the value of an Identity field to a variable or something else before you have saved the record?

You should use a base class if there really isn't any reason for other developers to desire using their own base class in addition to your type's members **and** you foresee versioning issues (see http://haacked.com/archive/2008/02/21/versioning-issues-with-abstract-base-classes-and-interfaces.aspx).

How to check if a directory exists in a bash shell script |

What command can be used to check if a directory does or does not exist, within a bash shell script? |
I find the [double-bracket][1] version of `test` makes writing logic tests more natural:
if [[ -d "${DIRECTORY}" && ! -L "${DIRECTORY}" ]] ; then
echo "It's a bona-fide directory"

And I see that the [double-bracket operator is often faster][2].

The answer, I'm afraid, is it depends. It depends on the kind of application and the kind of users you have. Without knowing what the system is and the scope of the changes in the version, it is difficult to offer an answer.

Watch out for packing issues. In the example you gave all fields are at the obvious offsets because everything is on 4 byte boundaries but this will not always be the case. Viual C++ backs on 4 byte boundaries by default.

You have to walk the objects using reflection. Be careful as you do:
- Just allocating an object has some overhead in the JVM. The amount varies by JVM so you might make this value a parameter. At least make it a constant (8 bytes?) and apply to anything allocated.
- Just because `byte` is theoretically 1 by... |
In the same vein, adding a dummy field and then using CSS to hide it is a good way to trick the bots. If the field is submitted, you know a non-human probably completed the form.
Especially effective if you label/name the field something along the lines of **URL** or **website**. |

You have to measure it with a tool, or estimate it by hand, and it depends on the JVM you are using.

Firstly "the size of an object" isn't a well-defined concept in Java. You could mean the object itself, with just its members, the Object and all objects it refers to (the reference graph).
