  • How can I show the contents of a file at a specific state of a git repo?

    - by richcollins
    I want to show the contents of a file given by a path at a specific state of a git repo. I unsuccessfully tried this: git show f825334150cd4bc8f46656b2daa8fa1e92f7796d:Katana/source/Git/GitLocalBranch.h fatal: ambiguous argument 'f825334150cd4bc8f46656b2daa8fa1e92f7796d:Katana/source/Git/GitLocalBranch.h': unknown revision or path not in the working tree. Use '--' to separate paths from revisions The commit in question didn't modify the file specified. How can I show the contents of a file at a given state (specified by a commit hash) regardless of the involvement of the file in the commit?

  • Connect to MySQL in Ruby using NetBeans

    - by Varun
    I've downloaded the "dbd-mysql-0.4.4.zip" and linked it to my project. While I try to run a demo code from NetBeans the very first line require "dbi" gives me an error. Is there a different way to do it? I also tried jruby setup.rb config --with=dbi,dbd_mysql from the command prompt and it gave me the following error: config: unknown option --with=dbi,dbd_mysql Try 'ruby setup.rb --help' for detailed usage. Any suggestions please?

    - by Matey
    What is the best way to produce several tables of unknown size on the same worksheet? Values will be pulled from an oracle database and are used as values on several tables.

  • R segfault when running via Rpy on linux

    - by Zhang18
    I'm running R via Rpy on a redhat linux distribution. Periodically I'll encounter this error message: *** caught segfault *** address (nil), cause 'unknown' And the entire program dies right there. It usually occurs when I run a lot of regression r.lm(). But by simply running the identical code again, the problem may or may not go away (so not always reproduceable). Does anyone know what might be causing this, and/or how I can prevent it from happening?

Where can I find a concise, clear explanation of the recent (5 years) development of java? What are key elements to understand?

  • How to pass non-fatal warnings from a library

    - by wRAR
    A library function parses a file and returns an object. If a parser encounters unknown data, missing values etc., it shouldn't throw an exception and stop parsing (because this is not fatal), but there should be a way to pass information about these things to a caller (so that warnings can be displayed in the UI, for example). How can these warning be returned? I'm thinking of passing a callback function/object into the library, are there any other possible solutions?
