Recently I was part of a call with Daniel and Lars to discuss Zettelkasten, a system for building up a cross-referenced archive of notes to help with research and study that has been getting a lot of discussion recently, the key thing being the building of links between ideas. Tomas Vik provided an overview of […]
A short while ago Daniel, Lars and I met to discuss Russ Cox’s excellent essay Our Software Dependency Problem. This essay looks at software reuse in general, especially in the context of modern distribution methods like PyPI and NPM which make the whole process much more frictionless than traditional distribution methods used with languages like […]
This year’s audio miniconference happened last month in Lyon, sponsored by Intel. Thanks to everyone who attended, this event is all about conversations between people, and to Alexandre Belloni for organizing the conference dinner. We started off with Curtis Malainey talking us through some UCM extensions that ChromeOS has been using. There was general enthusiasm […]
The audio miniconference was held on the 21st in the offices of Cirrus Logic in Edinburgh with 15 attendees from across the industry including userspace and kernel developers, with people from several OS vendors and a range of silicon companies.
As in previous years we’re trying to organize an audio miniconference so we can get together and talk through issues, especially design decisons, face to face. This year’s event will be held on Sunday October 21st in Edinburgh, the day before ELC Europe starts there. Cirrus Logic have generously offered to host this in their Edinburgh office: 7B […]
I recently got a Bronica SQ-Ai medium format film camera which came with the Motor Drive SQ-i. Since I couldn’t find any documentation at all about it on the internet and had to figure it out for myself I figured I’d put what I figured out here. Hopefully this will help the next person trying […]
It’s really common for pitches to managements within companies about Linux kernel upstreaming to focus on cost savings to vendors from getting their code into the kernel, especially in the embedded space. These benefits are definitely real, especially for vendors trying to address the general market or extend the lifetime of their devices, but they […]
This weekend Toby Churchill kindly hosted a hacking weekend for OpenTAC – myself, Michael Grzeschik, Steve McIntyre and Andy Simpkins got together to bring up the remaining bits of the hardware on the current board revision and get some of the low level tooling like production flashing for the FTDI serial ports on the board up […]
The biggest change we’ve seen in the Linux kernel for ARM over the past few years has been the transition to providing descriptions of the hardware in systems via device tree. This splits out the description of the devices in the system that can’t be automatically enumerated from the kernel into a separate binary instead […]
Just over a year ago I implemented an optimization to the SPI core code in Linux that avoids some needless context switches to a worker thread in the main data path that most clients use. This was really nice, it was simple to do but saved a bunch of work for most drivers using SPI and made things […]
