Well, it's exam time so it's been a while since I last posted. Only 4 days left though! I'll be back with more stuff to post soon...
PNG images are great for Web work, but there's one problem that was really getting on my nerves: the color correction problem. PNG images, like many other formats, support embedded ICC profiles for color management. For websites this feature can become a big hassle since some Internet browsers (namely, Safari 3.x and up) will adjust the gamma and colors of images according to their embedded profiles, but the colors defined in CSS stylesheets are viewed with the native color profile. So if an image with an embedded ICC profile is used in combination with "background: " rules defined in a CSS stylesheet, the image will not match the background color of the page!
First, GIMP requires a bit of setup:
- Select the color profile for your display by selecting Edit > Preferences from the menu and clicking on the Color Management section
- Set Mode of Operation to Color managed display
- From the Monitor Profile drop-down box, choose Select color profile from disk... and select the ICC profile which is you are currently using (tip: On OS X, ICC profiles are stored in /Library/ColorSync)
Once GIMP has been informed about which ICC profile your display is using, it can convert embedded profiles to the sRGB workspace:
- Open the image you want to convert
- Select Image > Mode > Assign from the menu and ensure that the sRGB profile is currently assigned
- Select Image > Mode > Convert from the menu and select the ICC profile that your display is using (the same one you chose in the setup sets)
- Save the image and if applicable, pass it through pngcrush to make it smaller
I have to admit, I'm pretty curious about what the giant botnet of Conficker-infected computers is going to start doing tomorrow. A large-scale denial of service attack is my first guess, but my instinct tells me there's something bigger in store... Either way, my clock currently reads 11:53PM so we're about to find out!
Edit: Did some quick research and it looks like the media hype got me. The only thing that's changing is the method which one variant (and not even the most popular one) receives new instructions.
The 500GB SATA drive in an external enclosure that I use for backups (eSATA/USB 2.0 connectivity) is currently NTFS-formatted for compatibility reasons. I would much prefer to use ext3 or HFS+, but it's pretty hard to get those two working correctly on all operating systems. Thanks to NTFS-3G and (Mac)Fuse, I can reliably access NTFS partitions on Linux, OS X and Windows (of course) so it's become my FS of choice when it comes to compatibility.
Unfortunately, that means that the drive becomes horribly fragmented (and pretty quickly, too). I decided to do a defrag today and found that the NTFS partition was 38% fragmented with 78% file fragmentation... Yuck. I'm going to be really happy when there's a filesystem that I can use on all operating systems that doesn't fragment or choke all the time. Ext2/3 was looking like a pretty good for the "doesn't fragment" part, but the ext2fsx project for OS X seems to have died out and ext2fsd, the only driver I've found for Windows that supports ext3 filesystems with inode sizes > 128, tends to bluescreen a lot. Back to waiting, I guess...
I realized that I had my Drupal permissions set wrong and users who were not registered could not vote (I have also disabled user registration for now). I fixed the settings so if you cannot see the voting options, just refresh the page and they should appear on bottom left side of the page.
