As mentioned a while ago, I was looking for a firmware packager that would allow for "user uploads a signed bundle" style upgrades for hardware devices.  Esky is similar (even a similar on-disk layout), but focused on cross-platform and distutils-based "application" setup.  Fussy is intended for "core of a system" setups, where the entire user ...

Query came up on PyOpenGL-dev this morning about how to handle GLchar pointer arguments.  These are binary-specified arguments, they are human-readable text *most* of the time, ascii source-code and identifiers, that kind of thing, but nothing about GLchar pointer requires that they be ascii.  They *are* 8-bit character strings (that's what GLchar pointer means).

But ...

I'm wondering if this package exists, preferably in Python (well, I *know* it exists, as I wrote it for a commercial project, and can't use it any more.  I'm hoping there's an Open Source version I can enhance for future use):

• bundle a .tar.gz (signed, optionally encrypted) for delivery to embedded platforms
• on platform, decrypt ...

Spent the afternoon at Research in Action (at University of Toronto).  Highlights:

• big classical (i.e. right out of the textbook) neural network used for road detection in satellite imagery; okay results, huge amounts of computing power involved; not sure it's really all that much better than a hand-coded solution, but it did seem to work ...
