• How did my reputation drop over night from 901 points to 471? [closed]

  - by AspOnMyNet

  I'm not sure how important it is having a large reputation number, but then I'm also worried someone hacked into my account or something, since I don't see how else it would be possible to loose 500 points in a single day ( hopefully this non-programming related post won't cause another 500 drop :) ). Any idea why this happened? thanx

• Is copying /var/lib/mysql a good alterntive to mysqldump?

  - by kemp

  Since I'm making a full backup of my entire debian system, I was thinking if having a copy of /var/lib/mysql directory is a viable alternative to dumping tables with mysqldump. are all informations needed contained in that directory? can single tables be imported in another mysql? can there be problems while restoring those files on a (probably slightly) different mysql server version?

  - by Michiel Borkent

  I regularly listen to the podcasts DotNetRocks and Software Engineering Radio. Lately I have become more interested in Clojure.

• Launch another instance of Java app on Mac

  - by TomA

  I have a Mac Java app bundle that has problems opening an OpenGL window from a SWT dialog in a single process. It just doesn't work. To solve this problem I would like to open a SWT dialog in one instance of the Java app and then have it launch another instance of itself with a parameter saying "this time open the OpenGL window". The part I don't know how to do is finding out what "itself" is on a Mac. How can I do that?

• Are Multi-column Primary Keys in MySQL a optimisation problem?

  - by David

  Been looking into using multi-column primary keys and as performance is extremely important with the size of traffic and database I need to know if there is anything to consider before I start throwing out the unique ID method on many of my tables and start using mulit column primary keys. So, what are the performance/optimisation pros/cons to using multi column primary keys versus a basic single column, auto-inc primary key?

• Is there a sample Rails application with a number of cucumber stories?

  - by Otto

  I'm trying to really understand Cucumber stories. I get it, but I'm really slow writing them. I think if I saw a good fleshed out application, I'd get closer to where I want to be. There are some samples out there, but there aren't any I can find with a single app with some non-contrived example stories. Are there any existing ones?

• Practical examples of using symbols in Scala?

  - by Jesper

  Scala has symbols - names that start with a single quote ' and which are a kind of string constants. I know symbols from Ruby (where they start with a colon). In Ruby they are used for some meta-programming tasks, like generating getters and setters for member variables (for example attr_reader :name to generate a getter for name). I haven't seen a lot of use of symbols in Scala code yet. What are practical uses for symbols in Scala?

This shows B1 C3 - the inverse of what I expected! Can someone explain? For getting the expected output I do: hexdump -C test.txt 00000000 c3 b1 |..| 00000002 I was thinking I understand encoding systems..
