  I have a few log files like these: /var/log/pureftpd.log /var/log/pureftpd.log-20100328 /var/log/pureftpd.log-20100322 Is it possible to load all of them into a single filehandle or will I need to load each of them separately?

• How can I generate a git diff of what's changed since the last time I pulled?

  - by Teflon Ted

  I'd like to script, preferably in rake, the following actions into a single command: Get the version of my local git repository. Git pull the latest code. Git diff from the version I extracted in step #1 to what is now in my local repository. In other words, I want to get the latest code form the central repository and immediately generate a diff of what's changed since the last time I pulled.

• int datatype in 64bit JVM. Is it more "inefficient" than long?

  - by Zwei Steinen

  I heard that using shorts on 32bit system is just more inefficient than using ints. Is this the same for ints on a 64bit system? Python recently(?) basically merged ints with long and has basically a single datatype long, right? If you are sure that your app. will only run on 64bit then, is it even conceivable (potentially a good idea) to use long for everything in Java?

I am asking what is the cause of this behaviour?

  - by Rafael E. Belliard

  I am using Fluent NHibernate's (1.0 RTM) automapping feature to create my oracle database schema. My issue is that all the tables are using a single "hibernate-sequence", whereas I would prefer (and my boss would demand) a sequence generator for each table. Any ideas?

• Why is a .net generic dictionary so big

  - by thefroatgt

  I am serializing a generic dictionary in VB.net and I am very surprised that it is about 1.3kb with a single item. Am I doing something wrong, or is there something else I should be doing? I have a large number of dictionaries and it is killing me to send them all across the wire. The code I use for serialization is Dim dictionary As New Dictionary(Of Integer, Integer) Dim stream As New MemoryStream Dim bformatter As New BinaryFormatter() dictionary.Add(1, 1) bformatter.Serialize(stream, dictionary) Dim len As Long = stream.Length

• How to build jars from IntelliJ properly?

  - by ripper234

  I have a project that contains a single module, and some dependencies. I'd like to create a jar, in a separate directory, that contains the compiled module. In addition, I'd like to have the dependencies present beside my module. No matter how I twist IntelliJ's "build jar" process, the output of my module appears empty (besides a META-INF file).

• Is it reasonable to use OpenGL for desktop applications?

  - by JamesK89

  I've been writing a small desktop gadget-type application that displays scrolling text along the bottom of the screen (Similar to the old CNN news ticker), however the performance of GDI is just unsatisfactory (As high as 8-12% on a quad core and 20% on a single core) even after I've attempted to clean out bottlenecks. I was considering using OpenGL instead to render everything, but I don't know if that is a reasonable option to require users to have hardware acceleration for a tiny app like this. Does anybody have any input on this?

• Question about factory classes

  - by devoured elysium

  Currently I have created a ABCFactory class that has a single method creating ABC objects. Now that I think of it, maybe instead of having a factory, I could just make a static method in my ABC Method. What are the pro's and con's on making this change? Will it not lead to the same? I don't foresee having other classes inherit ABC, but one never knows! Thanks

  (I am running Linux Ubuntu 9.10, so the extension for an executable is executablefile.out) I am just getting into modular programming (programming with multiple files) in C and I want to know how to compile multiple files in a single makefile. For example, what would be the makefile to compile these files: main.c, dbAdapter.c, dbAdapter.h? (By the way, If you haven't figured it out yet, the main function is in main.c) Also could someone post a link to the documentation of a makefile?

  I've researched for hours and still haven't found a robust, non-absolute-positioning solution for displaying multiple-column forms and values without using TABLE tags. Can someone point me to a resource specifically oriented towards reproducing table-based, multiple-column forms (like name and address forms) in CSS to standards? Most of the forms I see only have a single column with field/value.
