Lens-Artists Challenge #342: It’s a Wild Life!

This week Egídio from Through Brazilian Eyes is hosting the Challenge, and his theme is, ‘It’s a Wild Life‘. ‘What is wild?’ Egídio asks. The dictionary says it is, ‘living in a state of nature, untamed, uncivilized, not inhabited or cultivated, uncontrolled, unruly,’ and Egídio asks the question, ‘I am curious about what you consider wild. Is it a place, a person, wildlife, wildflowers, or something else?’

Living in the countryside we get a lot of wildlife, cranes nesting on electricity pylons, eagles living in the nearby woods, but we only ever see them from afar. So I’m left with the smaller animals and insects that dominate the local woodlands, and occasionally even land in our garden: flies, bees, reptiles, and so forth.

We used to have some large cypress trees in the garden, and occasionally we would get spiders making a web in the spaces between two trees. Here the spider is in the middle of preparing their lunch.

This dragonfly probably accidentally flew into the shade in our garden. Fortunately we were able to encourage it back into the sunshine, where it perked up and soon flew off.

The neighbours have a small orchard, and a few years ago it was completely overgrown. I would take my camera out to photograph the flowers and insects in the spring, and this bee was feeding from a flower. Taken with a zoom lens, I love this image.

After the rain one day, I came across this wasp on a rosebush in the garden. It was still quite cold, and a little sluggish. Just as well, I’m very wary of wasps.

In the woods behind our house, my photos are not limited to the trees. This fly was caught from a really low angle, and the lovely colour in the background is the clear blue sky.

We get a lot of small lizards everywhere in Portugal, and as often as not they’ll be spotted basking in the sun or running away when approached. This one, though, was caught in the shade on the wall of our office. It probably didn’t hang around for long, though. Just long enough for me to grab a portrait.

Themes for the Lens-Artists Challenge are posted each Saturday at 12:00 noon EST (which is 4pm, GMT) and anyone who wants to take part can po3st their images during the week. If you want to know more about the Challenge, details can be found here, and entries can be found on the WordPress reader using the tag ‘Lens-Artists’.

Today's bug is a `duperemove` infinite looping bug: github.com/markfasheh/duperemo

There `duperemove` was not able to dedupe against NoCOW file:

$ dd if=/dev/urandom bs=8M count=1 > a
$ touch b
$ chattr +C b
$ cat a >> b
$ ./duperemove -d -q --batchsize=0 --dedupe-options=partial,same a b
<hangup>

I noticed it about a month ago but got to debug it only today. It's a 0.15 regression. The fix is trivial once bisected.

Without the change dedupe hangs on NoCOW files as: $ dd if=/dev/urandom bs=8M count=1 &gt; a $ touch b $ chattr +C b $ cat a &gt;&gt; b $ lsattr a b ---------------------- a ---------------C------...

All new files my old `btrfs` filesystem creates are above 32-bit inode space:

$ touch a && stat '-c%i' a
11833717710

Very occasionally I build 32-bit `i686-linux` packages. Sometimes they fail to run against file with so large inodes.

Two casualties today:
- `doxygen`: github.com/doxygen/doxygen/pul
- `graphviz`: gitlab.com/graphviz/graphviz/-

Without the change doxygen fails to run when built against i686-linux target and installed on thew filesystem with 64-bit inodes (btrfs with many files in my case): $ doxygen -g &amp;&amp; doxygen ...
