- Fix font configuration on OSX
- Use Mac style key bindings on OSX

ganv 1.4.0 has been released. Ganv is an interactive Gtk canvas widget for graph-based interfaces (patchers, modular synthesizers, finite state automata, interactive graphs, etc). For more information, see http://drobilla.net/software/ganv.
- Begin using library and pkg-config names suitable for parallel installation. This version of flowcanvas is flowcanvas-1 and is NOT compatible with previous versions
- Clean up API and improve documentation.
- Add font size API
- Use system theme font size by default
- Size empty ports in font based units so they look right when zoomed
- Adjust padding and placement to precisely fit text
- Add ability to select connections directly
- Add Connection::set_curved()
- Fix lingering handle when deleting connections
- Dramatically increase performance by rendering text manually rather than using the truly awful Gnome::Canvas::Text.
- Remove use of boost smart pointers. Adding and removing from containers (e.g. Canvas, Module) is now done automatically.
- Clean up API/ABI by hiding private implementations.
- Add ability to select connections by their handles, either individually or in groups with rect select.
- Further slight improvements in memory consumption and alignment.
- Improve scalability to graphs with many connections (eliminate linear connection searches and redundant connection collections).
- Switch to GPLv3+
Disabling the obnoxious lights on the Evoluent Vertical Mouse 4
I've been a fan of the Vertical Mouse for a while now, since the extreme wrist pronation of a conventional horizontal mouse aggravates my wrist. Unfortunately, however, Evoluent saw fit to put a blindingly bright blue lit-up logo on the back of the latest version (much to the delight of absolutely nobody in their target market). This is particularly problematic if you work late or sleep in the same room as your computer (blue light messes with your sleep cycle, hence tools like Redshift).
After unplugging my mouse every night for so long, I finally decided to tear the thing apart and see how easy it would be to disable those lights. It turns out this is very easy, you don't even need to desolder anything. There are four screw holes hidden under the label and front pad on the bottom. You don't need to remove the other two pads like I did in the process of figuring this out.
Remove all four screws and the top should come off easily. There are ribbon cables connecting the buttons, though, so don't pull too hard. Now you can see the battery of LEDS.
Luckily, this pointless board is connected with a header, so you can simply unplug it, and reassemble the mouse.
Pretty names in Patchage via Jack Metadata
The much-awaited (by me, at least) Jack metadata API has arrived. This will allow us to easily achieve many new things with minimal/nonexistent API friction. One of the simplest and most obvious is pretty names for Jack clients and ports, so I've chosen this as the first thing to tackle (as part of a drive to get Patchage polished up for a much overdue release).
Unfortunately, as far as I can tell, there is a chicken & egg scenario here since nothing is setting this metadata yet. So, I've made Jalv and Ingen both set pretty names for their ports. In the case of Jalv, the "pretty name" is the label given in the plugin data (distinct from the LV2 "symbol" which is restricted and unique).
Firing up Jalv with the Tal Dub III plugin (LV2 port courtesy KXStudio), we can see the port symbols, which are a bit awkward for end users with their prefixes and underscores. Conflating strong identifiers with human-readable labels is a serious design error I learned of the hard way, but that's a discussion for another time...
Enable "Human Names" in the view menu, or press C-h, and voilà, we see the pretty names set in Jack metadata (if present) instead.
The metadata API is very simple to use for ports, though there seems to be a hole in the API which makes it difficult to get the UUID for your client to set metadata (I want a simple jack_client_uuid, like jack_port_uuid, but it seems you have to get a string UUID and parse it to a jack_uuid_t, clunky enough that I just didn't bother). In any case, I am happy to see a low-friction mechanism in Jack which apps can use to share metadata towards making a better user experience.
It will be interesting to see what sort of information proves useful and becomes established/standard. For those of us of a mad scientist bent who live in a nest of patch cables, a CV tag seems like another obvious simple step, but for everyone, a big step is finally having meaningful port grouping and channel roles. I have always liked to joke that Jack (like LADSPA) doesn't really even do stereo, but with metadata, we can mark up stereo, 5.1, Ambisonics, etc., and other clients will be able to make sense of the channel assignments without resorting to dirty kludges based on guessing from names. All without changing the ABI one bit. Good stuff.
