Open Source... Cooking!

Open Source... Cooking?!?!
be careful with stupid ideas:
“Hey, you have a kitchen, we could cook for 30 people...”
first event in April 2010
around 15 events so far, Fridays after work
20-30 participants, max. 40 possible
not so stupid idea anymore:
”meeting away from PC and smartphone”,
people nowadays bring their kids and families

Indeed, it’s Open Source!
cooking per “open source principles”
we enjoy working together
we are a community
we have adventurous interest and excitement
we learn from our mistakes and share knowledge
everyone contributes what they’re best at
we motivate others to contribute
coordination is key... but a bit chaotic :-)
everyone benefits from the result – and it’s tasty!

Twitter: @floeff
“Call for Recipes”
recipe proposals via e-mail and social media
→ no ”spaghetti code”, but really good food
→ Japanese, Mexican, Hungarian, Indian, with local support
everyone’s included
vegetarians, vegans
allergies
Who (dis)likes what kind of food?
betatest at home ;-)
8
Twitter: @floeff
Compiling things...
build requirements: a group of people will go
shopping at a large grocery store together
(ETA: three hours!)
“project management”: amounts and costs
estimated by spreadsheet and search engine
costs shared, 5-15 € per participant
way less expensive than good food in a restaurant
9
Twitter: @floeff
Release Engineering
”package maintainers“ for each of the three menu courses
cooking together
disseminators: only a few can actually cook
stove has a scalability limit, only four hotplates
parallelization is important
18 kg tomatoes, 100 eggs, sixpack of wine
time-based release model, sort of…
main course between 21:30 and 01:30
documentation could use some improvements ;-)
some recipes not public yet
10
Twitter: @floeff
post-install scripts
cleanup process hard to set up (washing the dishes...)
donation of food to Salvation Army, so not only us,
but also others have a wonderful evening
for us, it’s just 1 € more, but for others it means a lot
we are geeks, so more ideas on the way
cooking abroad
working with celebrity chef?
(first TV show already asked!)
finally buy the 700 € pumpkin ;-)
ask a grocery store to donate 1 € for people in need
for each Euro we spend there for food
11
Twitter: @floeff
Long-term maintenance, sustainability
last event took place several years ago
key people not available anymore
→ not because of lack of interest,
but people’s life and hobbies change
someone needs to “wear the (chef’s) hat”
→ create projects in a sustainable way,
avoid ”bus factors”
