No gingerbread work tonight

I spent tonight working on a super secret project.  Hopefully I'll be able to say more in a few weeks.

Python and libpuzzle

As much as I've dogged on Python in the past (significant whitespace, really?), I've got to admit that it's got some cool features too. For example, I'm playing with libpuzzle  (a library for visually comparing images).  It has a command line utility and a C and PHP API.  Unfortunately, the CLI utility doesn't allow one to dump the raw comparison vector, and it's a PITA to write C just to play with a library. Python's native "ctypes" to the rescue! from ctypes import * class PuzzleCvec(Structure): _fields_ = [("sizeof_vec", c_size_t), ("vec", c_char_p)] class PuzzleCompressedCvec(Structure): _fields_ = [("sizeof_compressed_vec", c_size_t), ("vec", c_char_p)] class PuzzleContext(Structure): _fields_ = [("puzzle_max_width", c_uint), ("puzzle_max_height", c_uint), ("puzzle_lambdas", c_uint), ...

If it builds, ship it...

I've finally gotten a working build.  It turns out what I really needed was to get up @ 0630, take a shower, and just plug away. Anyhow, the source is up on github:   https://github.com/coredog64 I still need to get it to build an image for the Streak before I can actually test it.

Building Amazon Linux RPMs with Fedora Mock

Fedora's 'mock' tool provides a much more convenient way to build RPMs than using 'rpmbuild'.  It creates a chroot environment for your target OS and will install required dependencies. I've been running into limitations on the version of CollectD that ships with Amazon Linux, so I thought it wouldn't be that difficult to use mock to build an updated version complete with some missing plugins.  I knew that it generally worked, as I was able to use the specfile from the project to build for EPEL6 using Fedora 26.  Man, was I wrong about how easy it would be for Amazon Linux. I won't go into details here, but it's worth mentioning that the CollectD project documentation calls out that the specfile in their contrib directory is generally out of date.  That is 100% correct, so you'll need to budget some time for tweaking it. The first issue is that there are some packages in EPEL that can't be installed in Amazon Linux.  The most aggravatin...
