glad to hear.

Nice, I'll keep an eye on that.

I would really like to see a live project plan being updated somewhere.
It would be complementary to the blog.
It does not have to be Phab, Phab could be heavy for the smallest
items. Just do not dismiss Phab on the first hand, check what it has
and whether it could be useful for you. We have a long term plan to
migrate everything to Phab once it's up for it: bugs, tasks, patch
reviews, CI and testing...
There are also hierarchical TODO list trackers in the web, though I
haven't personally used any yet.

Cool, these would be the top-level tasks in your project plan. Then you
start thinking what you need to actually do to achieve each, which
should result in sub-tasks, or maybe you do the sub-tasks already while
at it, so you only need to write down what you did.
Often when working on one thing, you get an idea of what you need to do
for another thing, and I've noticed it really helps to write the ideas
down. Well, I could also be just a scatterbrain since it helps me to
Just write down everything that comes to mind, so you don't later
forget. It will then help us to discuss your tasks and keep your
project scope under control.
Don't forget the paper work that GSoC requires, those should be in your
project plan too. I've understood that there may be quite some
reporting to do.

Don't wait that long. If you write patches that make sense on their
own, like clean-ups, adding comments, refactoring, fixes, etc. send
them out ASAP. Gathering a long list of commits can become a burden to
rebase, and is also less attractive for reviewers.
It is good to build up a routine of casually sending small patches
upstream. It helps to keep your backlog smaller and spreads out the
review effort over a long time.
OTOH, patches that work towards a new feature or design step by step,
which are not quite clear on "why" on their own, often require the
complete series finishing the feature before they can be meaningfully
reviewed. An example of a such big question is "is this architecture
I would recommend to err on sending too early, as it also nicely
shows your progress. You can also send "RFC" when you would like to
have some comments, but the patches are not finished.

Ok, but remember that we need some material to be able to write the
mid-term evaluations of your work. Actively sending patches whenever
you have something will help with that.

Ok, very good.
Kat reminded me, that you should be in contact with us on a daily
basis about your progress. Any sign of life would be good: a line in
irc, an email on the list, a commit in your repo, a post in your
blog... This is so that we see you haven't been hit by a truck. :-)
After all, this is supposed to be your day job for the summer.
Even just noting you didn't have time to do anything is worthwhile.
I'll try to keep in mind the Mon-Wed absence, etc.

Ah yes, cool.
