Can Maven be made less verbose? |
|maven-2| |
I'm sometimes forced to use Maven (eww). It spews out far too many lines of output to my taste (I like the Unix way: no news is good news). The lines I want to get rid of are marked [INFO], but I couldn't find any mention of an argument or config settings that controls the verbosity of Maven. Is there no LOG4J-like ... |
I would use SSIS or DTS (assuming you are talking about MSSQL). They are made for that purpose and work with SPs if you need them.
Another option is to preprocess the data using Perl. Even though it sounds like a wierd suggestion, Perl is actually extremely fast in these scenarios. I've used it in the past to proces... |

If you are talking about virtual destructors (in C++) then they should always be used if you are using your child classes polymorphically.
class A
{
~A();
}
class B : public A
{
~B();
}
A* pB = new B();
delete pB; // NOTE: WILL NOT CALL B's destructor

There are a lot of factors at play here that you've left out. What kind of database is it? Are those tables indexed? How are they indexed? How large are those tables?

One thing that hasn't been mentioned yet is that it's perfectly possible to use git in the [same centralized manner that you're used to with Subversion][1]. It really is an outstanding piece of software.

I am not sure this is an anti-pattern. I have commonly seen this used instead of exceptions for performance reasons, or perhaps to make the fact that the method can fail more explicit. To me, it seems to be a personal preference rather than an anti-pattern.

HttpModules attach to the ASP.NET request processing pipeline itself. The httpModule itself must take care of figuring out which requests it wants to act on and which requests it wants to ignore.
This can f. ex. be achieved by looking at the context.Request.Path property. |

When you are in Enterprise Manager or SSMS, can you see the name of the database that you are talking about? There might be a leftover database in a funky state.

This is really two questions, you realize. :-) The answer to the first one is that it's never *mandatory*, but honestly, parsing HTML request parameters directly is pretty horrible right from the start. I don't want to do it even once, so I tend to go toward a framework relatively early on.

I hate to say it, but move on from WinHelp. It's been deprecated for a reason. We were able to migrate to a .chm in only a few hours. It's pretty straight-forward to use the newer help authoring tools, and newer formats like .chm give you benefits like cascading style sheets. |

Under the hood, it actually creates and appends to a StringBuffer, calling toString() on the result. So it actually doesn't matter which you use anymore.
