>How to print from NeoOffice at more than 300dpi

One of the limitations in NeoOffice 2.0 and 2.1 is that the maximum resolution when printing 300dpi. This is especially an issue when printing images with tiny details, such as screenshots. Photos are normally just fine at 300dpi.

However, there is an easy way around that:

  1. export to PDF;
  2. open in Adobe Reader and print from there.

That’s it, now you can have higher quality output.


>Undo recent Subversion commits (updated)

>Here’s a quick HOWTO for undoing recent Subversion commits. Do:

svn merge -r NEW:OLD PATH


  • NEW is the new (bad) revision;
  • OLD is the old (good) revision;
  • PATH is the file or directory to revert.

For example:

svn merge -r 1680:1667 src/


  • Don’t forget to commit afterwards.
  • Instead of a revision number, you can also use the literal string HEAD for the most recent revision.
  • You can only pass one path at a time, but this can be a directory name instead of just a file name. To process multiple paths in a row on a UNIX/Linux/Mac system, use:
    for f in path1 path2 path3; do svn merge -r NEW:OLD $f; done

>Mighty Mouse scrolling woes

The Apple Mighty Mouse looks quite good, IMHO, but after only a few months the scroll wheel starts behaving oddly. I have both a wired and a wireless (Bluetooth) version and both have stopped scrolling downwards.

This appears to be a widely known problem with these mice. However, the main hurdle is that they cannot be cleaned internally like older mice could be, in the past.

Just a warning for those who consider buying it: make sure there’s no dirt coming anywhere near your scroll button; poking your nose is a recipe for quick disaster 🙂


>SVK version control system (updated)

>Update (August 27, 2009): It’s probably better to use git-svn (instead of SVK), a conduit between local git repositories and a regular remote Subversion repository.

The original blog post follows below.

A few months ago I switched from CVS to Subversion. All seemed OK, until I tried to add Apple iWork documents (Keynote and Pages) in the repository. These ‘documents’ are in fact complete directories. That’s fine so far, but then when any of these programs saves the document, they purge unknown subdirectories, including those that happen to be called .svn.

So I went looking for a Subversion-oriented solution to work around this issue. What I found instead was not a work-around, but a product that does not expose the weakness Subversion has. It’s called SVK. While based on Subversion, it offers various improvements over the latter:

  • local commits – commit to the remote repository later, keeping all log messages; allows you to work offline for a while and sync when you’re online;
  • faster operations – the ‘status’ and ‘log’ commands are claimed to be much faster;
  • no metadata in subdirectories – this information is stored elsewhere in the file system;
  • smarter merge – making branches less painful;
  • log filtering – find that commit you’re looking for;
  • combine import and checkout – it’s possible to import a directory and convert it to a working copy at the same time, boosting productivity;

Seems there are some reasons to at least consider it for larger projects.
