Steve Kemp

So I've been busy.

The past few days I've been working on my mail client which has resulted in a lot of improvements to drawing, display and correctness.

Since then I've been working on adding GPG-support. My naive attempt was to extract the signature, and the appropriate body-part from the message. Write them both to disk then I could validate via:

gpg --verify msg.sig msg

However that failed, and it took me a long to work out why. I downloaded the source to mutt, which can correctly verify an attached-signature, then hacked lib.c to neuter the mutt_unlink function. That left me with a bunch of files inside $TEMPFILE one of which provided the epiphany.

A message which is to be validated is indeed written out to disk, just as I would have done, as is the signature. Ignoring the signature the message is interesting:

Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: quoted-printable

The reason I'd failed to validate my message-body was because I'd already decoded the text of the MIME-part, and I'd also lost the prefixed two lines "Content-type:.." and Content-Transfer:.... I'm currently trying to work out if it is possible to get access to the RAW MIME-part-text in GMIME.

Anyway that learning aside I've made a sleazy hack which just shells out to mimegpg, and this allows me to validate GPG signatures! That's not the solution I'd prefer, but that said it does work, and it works with inline-signed messages as well as messages with application/pgp-signature MIME-parts.

Changing the subject now. I wonder how many people read to the end anyway?

I've been in Finland for almost a year now. Recently I was looking over websites and I saw that the domain steve.fi was going to expire in a few weeks. So I started obsessively watching it. Today I claimed it.

So I'll be slowly moving things from beneath steve.org.uk to use the new home steve.fi.

I also setup a mini-portfolio/reference site at http://steve.kemp.fi/ - which was a domain I registered while I was unsure if I could get steve.fi.

Finally now is a good time to share more interesting news:

  • I've been reinstated as a Debian developer.
  • We're having a baby.
    • Interesting times.

Debian Bits

DebConf16 schedule available

DebConf16 will be held this and next week in Cape Town, South Africa, and we're happy to announce that the schedule is already available. Of course, it is still possible for some minor changes to happen!

The DebCamp Sprints already started on 23 June 2016.

DebConf will open on Saturday, 2 July 2016 with the Open Festival, where events of interest to a wider audience are offered, ranging from topics specific to Debian to a wider appreciation of the open and maker movements (and not just IT-related). Hackers, makers, hobbyists and other interested parties are invited to share their activities with DebConf attendees and the public at the University of Cape Town, whether in form of workshops, lightning talks, install parties, art exhibition or posters. Additionally, a Job Fair will take place on Saturday, and its job wall will be available throughout DebConf.

The full schedule of the Debian Conference thorough the week is published. After the Open Festival, the conference will continue with more than 85 talks and BoFs (informal gatherings and discussions within Debian teams), including not only software development and packaging but also areas like translation, documentation, artwork, testing, specialized derivatives, maintenance of the community infrastructure, and other.

There will also be also a plethora of social events, such as our traditional cheese and wine party, our group photo and our day trip.

DebConf talks will be broadcast live on the Internet when possible, and videos of the talks will be published on the web along with the presentation slides.

DebConf is committed to a safe and welcome environment for all participants. See the DebConf Code of Conduct and the Debian Code of Conduct for more details on this.

Debian thanks the commitment of numerous sponsors to support DebConf16, particularly our Platinum Sponsor Hewlett Packard Enterprise.
