O Jerusalem, Jerusalem, you who kill the prophets and stone those sent to you, how often I have longed to gather your children together, as a hen gathers her chicks under her wings, but you were not willing! – Luke 13:34

Yes, it was two years ago.

Yes, that makes me a ginormous slacker.

But after seeing the photos my friends took on their recent excursion to the Holy Land, I wanted to stitch together the panoramic photos I took. Some of them stitched up really well! Clicking the link will take you to a massive full-size version.

Well, our pictures have been available for quite a while, but I’ve been lazy and haven’t posted a link anywhere public. No longer: Here they are, all >6000 of them. Israel was a fantastic experience.

Fix missing thumbnails in Nautilus

As I begin assembling the picture package for my J-term trip to Israel and Palestine, I’ve run into a problem: with high-end digital cameras, the JPEG-compressed image files are larger than 5 MB, and Nautilus (the default Ubuntu file manager) won’t create thumbnails for pictures that size.

The solution: a bit of configuration in gconf-editor. Navigate to key /apps/nautilus/preferences and increase the size of thumbnail_limit to something more reasonable for modern cameras.

Two simple ways to recover photos from a broken SD card

I just got back from a 18 day trip to Israel and Palestine, and my classmate Dave’s SD card for his digital camera gave out right at the end of the trip. He gave me the card to try to recover the pictures, and I was pretty successful. Here’s what I did.

I needed to grab a pristine copy of the SD card’s data without hardware errors getting in the way. So I used dd to take a snapshot of the card:

sudo dd if=/dev/mmcblk0 of=sdcard.img bs=512b skip=1 conv=noerror

The /dev/mmcblk0 should be replaced with the location of your SD card reader. The magic sauce is conv=noerror, which prevented me from getting an error with Dave’s card about 40% into a 1G card.

First I tried recoverjpeg, available from your friendly local ubuntu repository. Run this program like so:

recoverjpeg -v sdcard.img

Simple and straightforward. This program recovered 108 pictures, all with EXIF data intact (except for no date/timestamps – oh well).

I also tried photorec, which is part of the testdisk package in Ubuntu. Photorec is more complicated, but it recovers more kinds of data too. Fortunately, it’s menu driven and pretty self explanatory. Invoke that program with:

photorec sdcard.img

Not only did this program recover most of the pictures (106), but it also grabbed all sorts of interesting metadata in the form of txt and xml files. It also did a good job with the EXIF data, except for the date/timestamps.

Altogether, I got slightly better results with recoverjpeg, and it was easier to use. Your Mileage May Vary. I was surprised at how easy it was to recover these images!

Special thanks to Cédric Blancher, whose article “Digital Photos Recovery” was very useful as I prepared this article.
