Kentaro Hayashi: Sharing mentoring a new Debian contributor experience, lots of fun

I recently did mentoring a new Debian contributor. This is carried out in a framework with OSS Gate on-boarding. In "OSS Gate on-boarding", recruit a new contributor who want to work on continuously. Then, corporation sponsor its employee as a mentor. Thus, employees can do it as a one of their job. During Aug - Oct period, I worked with a new debian contributor every 2h in a week. This experience is lots of fun, and learned a new things for me. The most important point is: a new Debian contributor aimed to do their work continuously even though mentoring period has finished. So, some of the work has been finished, but not for all. I tried to transfer knowledge for it. I'm looking forward that he makes things forward in consultation with other person's help.

Kentaro Hayashi: Grow your ideas for Debian Project

There may be some "If it could be ..." ideas for Debian Project. If idea is concreate and worth to make things forward, it should make a proposal for Project Funding. But it is a just an idea, or no afford to act as an executor role, that idea will not be achieved. I thought that It needs an incubator - complemental project. I've salvaged an idea from closed MR Add proposal about "Formalize reimbursement process" (!5) Merge Requests Freexian SARL / Project Funding GitLab I'm not confident whether mechanism works, but Debian needs change.

Kentaro Hayashi: Say Good-Bye and Thanks hal-flash

Today, hal-flash package was removed from Debian unstable. hal-flash is wrapper library for HAL which is not used nowadays. At that time, HAL was required because Adobe Primetime DRM uses libadobecp, but HAL was already replaced to udev or udisks. So we need emulation layer for HAL. hal-flash was it for such a purpose. (At least, hal-flash is required to play movies which uses Adobe DRM) hal-flash package was already orphaned years ago, and removed from unstable now. O: hal-flash -- Compatibility library to allow playback of Flash DRM content Thanks hal-flash package!
