Oedem/2010

OpenEmbedded Developers' Meeting 2010 will be in Cambridge, UK on the 29th and 30th of October. This is after http://www.embeddedlinuxconference.com/elc_europe10/index.html and will be held in the same place, the University Arms Hotel (http://www.devere.co.uk/our-locations/university-arms).

All developers and other interested parties are welcome.

Location

Darwin Suite in the University Arms Hotel Cambridge, England.

Registration

Due to restricted space at the venue, the number of attendees is limited to 30 poeple.

Agenda Suggestions

• FM: I would like to suggest a discussion on recipe quality and how to improve it. I must say that I am somewhat disappointed by the number of recipes that do not fetch or do not patch. How are we going to handle this
• FM: related to the previous: how to deal with orphaned recipes, distros and machines
• FM: suggest to re-institute the MAINTAINERS field, at least for distro and machine conf files but preferably also in recipes. Currently it is often not clear who maintains what
• FM: review/commit/revert policy (e.g. formalize the suggestion that NAKs need to be motivated and that submitted patches can be pushed if there is no neg feedback within say 2 weeks (even if there is no feedback at all).
• FM: maybe discuss the testing branch/procedures
• FM: usage of DEFAULT_PREFERENCE = "-1" (and more concrete: the creation of new recipes with DP = -1, that never seem to loose its DP)
• Khem: Libtool 2.4 upgrade.
• Khem: bitbake world. What do we do ?
• Khem: patchwork workflow
• Khem: Security updates how to handle
• Khem: Make LICENSE field mandatory in recipes
• Khem: Time based releases ( one a year)
• Hrw: recipes/ subdirectories (all "inherit opie" or "inherit palmtop" -> recipes/opie/ dir etc)
• RP: srctree, srcrev mess, pain with linux-wrs - time to rework the scm fetchers?
• RP: Proposal - merge fetch and unpack tasks
• LW: the recipe owner needs to well understand class implementation details, no consistency, no documentation, and subject to change.
• LW: BB2 and OE2 from scratch?

Travel

London Stansted airport is the nearest to Cambridge with regular service. (There is a small airport in Cambridge itself but I don't think any scheduled airlines operate from there anymore.)

For those travelling from Europe, Stansted is about a 30-minute train ride from Cambridge city centre and is served by Air Berlin, Ryanair and Germanwings among others. Luton airport is about 1 hour away by bus and is served by Easyjet.

For those travelling from further away, most long-haul flights arrive at Heathrow or Gatwick airports (although there is some transatlantic service into Stansted). Both Heathrow and Gatwick are about 2 hours from Cambridge by train or bus: the train is quicker but involves several changes in London, whereas the bus is slow but cheaper and less complicated.

If arriving at LHR airport, take the Piccadilly line from the Underground station and ride it all the way to Kings Cross St Pancras. Ascend to street level, follow signs to Kings Cross mainline station (not St Pancras: the two stations are different although they share a subway stop) and then look for trains to Cambridge or Kings Lynn on the departure board. There are usually two fast services and two slow services to Cambridge per hour: the slow trains are often overtaken by the fast ones en route so it may be best to wait for a fast service even if this is not the next to depart.

If arriving at LCY, take the DLR to Bank, then change to the Northern Line northbound. From Kings Cross St Pancras, proceed as for LHR, above.

Alternatively you can take the Eurostar to London St Pancras, which is 50 minutes from Cambridge by train.
