If you want to set a cell to a pixmap, ok no problem, but what about setting individual liststore values to a pixmap? You can’t do it directly unless you’re using a gtk.STOCK_ image. Here’s a way around that little problem.

ou may have noticed gtk has stopped showing images for buttons by default. Many apps have not bothered to check the default settings and just assumed that defining an image for a button meant it would show. Too bad the gtk devs decided to change the default value. But never fear, for there is a way to make sure the image shows without modifying the system or user preferences outside of your application!

ImageMagick falls short here. You can convert between the different pixel formats, and you can convert a vector file to a bitmap type, but it doesn’t convert pixels to vectors. Inkscape can convert pixmap to vectors. There’s also an online tool called Vector Magic.

Google Picasa is available as an rpm and deb for Linux. You can get it from google package repository if you already have that installed, but the latest version doesn’t appear to be available from there just yet. This app is run under a self contained wine installation.

Hugin is the GUI frontend for a bunch of image tools that allow you to stitch together multiple pictures with overlapping scenes to create a single panoramic images. The images don’t have to be the exact same color or from the same perspective. The image tools will manipulate the pictures in an attempt to smoothly blend everything into a single scene. You can create different kinds of stitched together images such as 360 degree fish eye and super wide angle views.

Cinepaint feels intuitive and relatively easy to use given the awesome manipulative power you have at your fingertips. If it seems familiar to you, that might be because it’s a fork of GIMP 1.0.4. Although it’s intended audience is video editors, you can use it for anything from gif, jpg, and tiff to cineon, hdr, xwd, xcf, and a long list of other formats. Cinepaint is for editing and touching up individual frames, not working with video files directly.

Instead of storing whole dd images, even if they’re just backups of small partitions, you can save space and bandwidth by piping dd into a compression utility like gzip. You can then unzip the files straight into sha1sum to get a checksum of what you just backed up.

Use the following steps to get an image of a HP Thin Client running as a virtual machine in VirtualBox. I’m running Fedora 11 and VirtualBox 3.0.0 r49315. The thin client is running a stripped down Debian Etchnhalf (no ‘less’ pager command, man pages?!) And finally, if you log in with root or another user, you’ll get to a full xfce desktop

I’ll start with a small DSL linux image. It’s only 50 meg, but it’s a pretty useful little distribution.
ls -lh dsl-4.4.10.iso

-rw-r–r– 1 ninja ninja 50M 2009-08-28 13:11 dsl-4.4.10.iso

Mount the original iso image you want to modify
mount -t iso9660 dsl-4.4.10.iso /mnt/original -o loop
Copy the everything that you just mounted to another …

How do you put pictures in your Outlook email signature so that everyone you send email to gets a little picture, and when they click on it, it sends them to a special website of your choosing? Well mom, that’s easy! Here’s how. But keep in mind, your screens may look a little different than mine, but it’s the same general get-r-dun process even if you’re using an older version of Outlook or Windows. I’m on 2008 server, so your mileage may vary.
