Passing a dictionary to a function in python as keyword parameters

I'd like to call a function in python using a dictionary. Here is some pseudo-code: d = dict(param='test') def f(param): print param f(d) This prints {'param': 'test'} but I'd like it to just print test. I'd like it to work similarly for more parameters: d = dict(p1=1, p2=2) def f2(p1,p2): print p1, p2 f2(d) Is this pos...

When to use friend class in c++

I was just brushing up on my cpp (I'm a java developer) and I came across the Friend class keyword which I forgot about for a while. Is this one of those features that's just part of the kitchen sink, or is there a good reason for doing this rather than just a vanilla getter? I understand the difference in that it limits who can access t...

Missing the 'with' keyword in C#

I was looking at the online help for the Infragistics control library today and saw some VB code that used the With keyword to set multiple properties on a tab control. It's been nearly 10 years since I've done any VB programming, and I had all but forgotten that this keyword even existed. Since I'm still relatively new to C#, I quickl...

Should the Java "this" keyword be used when it is optional?

From what I gather as a Java beginner, when accessing instance members, the "this" keyword may apparently be used, but is not mandatory. I wonder whether there is any official recommendation of sorts of a style guide (though I was unable to find anything in the actual Java style guide). How do people usually do this, or is there maybe...

How would you explain the risks of the $Log$ keyword?

I seem to get into an annual debate about the use of the $Log$ keyword. My point of view is this: $Log$ is white hot death. All it does is jam marginally relevant spam into your source files. Any information that anyone thinks they might be able to get from a $Log$ is more readily available from (and is likely to be more accurate ...

Would this be the correct place to use the java keyword "interface" ?

I'm rather new to Java. After just reading some info on path finding, I read about using an empty class as an "interface", for an unknown object type.

Equivalents to SQL Server TOP

In SQL Server, TOP may be used to return the first n number of rows in a query. For example, SELECT TOP 100 * FROM users ORDER BY id might be used to return the first 100 people that registered for a site. (This is not necessarily the best way, I am just using it as an example). My question is - What is the equivalent to TOP in other da...

Fastest way to lookup keywords. Any language, any system.

Daily I have 5 million or so unique keywords with an impression count for each one. I want to be able to look these keywords up by certain words so for instance if I have "ipod nano 4GB" I want to be able to pull that out if I search for "ipod", "nano", or "4GB". mySQL can't seem to handle that much data for what I want, I've tried Ber...

Clojure Parameters with Optional Flags

Avoiding Language Keyword Conflicts

How do you guys avoid keyword conflicts in your language? For example, I'm creating a class (VB 2008) to hold all the configuration variables for some reports we generate. Naturally, one of the variables is "Date". And of course you can't have anything named the same as a keyword. In VB 2008 you do have the option of surrounding a confl...
