• Why is it that I can include a header file in multiple cpp files that contains const int and not have a compiler error?

  - by tree

  Let's assume that I have files a.cpp b.cpp and file c.h. Both of the cpp files include the c.h file. The header file contains a bunch of const int definitions and when I compile them I get no errors and yet I can access those const as if they were global variables. So the question, why don't I get any compilation errors if I have multiple const definitions as well as these const int's having global-like scope?

• Check if something is a list

  - by 8EM

  What is the easiest way to check if something is a list? A method doSomething has the parameters a and b. In the method, it will loop through the list a and do something. I'd like a way to make sure a is a list, before looping through - thus avoiding an error or the unfortunate circumstance of passing in a string then getting back each letter. This question must have been asked before - however my googles failed me. Cheers.

• Java: Is there a way to obtain the bytecode for a class at runtime?

  - by Adam Paynter

  In Java, is there a way (at runtime) to obtain the bytecode which defined a particular class? Put another way, is there a way to obtain the byte[] array passed to ClassLoader.defineClass(String name, byte[] b, int off, int len) when a particular class was loaded? I see that this method is declared final, so creating a custom ClassLoader to intercept class definitions seems out of the question. In the past, I have used the class's ClassLoader to obtain the bytecode via the getResourceAsStream(String) method, but I would prefer a more canonical solution.

• Autovivification in C#

  - by Terrance

  Trying to wrap my head around perl's Autovivification and based on what it sounds like, It seems to work similar to dynamics in C# as a dynamic object is not assigned a type until runtime or, am I totally off here. If so then is there a comparable idea that I can bridge off of in C# that makes sense? Edit Okay so I'm apparently way off. So as second part of the 2 part question, is there anything conceptually comparable in C#?

• Multiple SiteMap: entries in robots.txt?

  - by user306942

  I have been searching around using Google but I can't find an answer to this question. A robots.txt file can contain the following line: Sitemap: http://www.mysite.com/sitemapindex.xml but is it possible to specify MULTIPLE sitemap index files in the robots.txt and have the search engines recognize that and crawl ALL of the sitemaps referenced in each sitemap index file? For example, will this work: Sitemap: http://www.mysite.com/sitemapindex1.xml Sitemap: http://www.mysite.com/sitemapindex2.xml Sitemap: http://www.mysite.com/sitemapindex3.xml

• What was the most refreshingly honest non-technical comment you saw?

  - by DVK

  OK, so we all saw the lists of "funny" or "bad" comments. However, today, when maintaining an old stored procedure, I stumbled upon a comment which I couldn't classify other than "refreshingly brutally honest", left by a previous maintainer around a really freakish (both performance and readability-wise) page-long query: -- Feel free to optimize this if you can understand what it means So, in the first (and hopefully only) poll type question in my history of Stack Overflow, I'd like to hear some other "refreshingly brutally honest" code comments you encountered or written.

• Checking type sizes in C with macros.

  - by Seisatsu

  I'm writing a program that needs to have unsigned types with definite sizes. I need a uint8, uint16, uint32, and uint64, and I need them defined in types.h, in a way that they will always be defined correctly regardless of platform. My question is, how can I check the sizes of different types on each platform using preprocessor macros, so that I can define my custom types correctly in the types.h header?

  Hi, Sorry if the question isn't phrased very well but I'm new to SSAS and don't know the correct terms. I have changed the name of a table and its columns. I am using said table as a dimension for my cube, so now the cube won't process. Presumably I need to make updates in the analysis server to reflect changes to the source database?

• Core Location and speed measurements

  - by Krumelur

  Does anyone know if Core Location in the iPhone OS uses anything but simple vector math to calculate speed? I've read that the GPS system can provide speed measurements that can be accurate when position is not (I believe using the Doppler shifts of the signals). I've tried and failed to see if the iPhone does this. The question is basically, does this data contain information or is it just convenience functions, using (filtered?) location data?
