Note that the booking above are for nights in the hotel, ie most people need to check out Monday morning. Talk to mpm if you need updates.

Here is a map containing the hotel, Unity Technologies and the closest train station to the hotel, the Österport station. Transportation options from the Copenhagen airport are either taking the train to Österport and walking, or a taxi from the airport. Taxi fare should be about 250 Kroner = $43 USD.

4. Directions

Regional trains go from the station beneath airport Terminal 3. You can purchase a train ticket at the automated machines to the side of the DSB ticket booth in Terminal 3. Tickets, valid for 3 fare zones, cost 36 DKK. A 10-ride discount card is available at 190 DKK; it must be stamped in the yellow machine on the platform prior to boarding the train or Metro. Tickets and discount cards are valid for one hour. You need to use a card with a PIN, so most US credit cards won't work. A debit card worked fine for durin42 last year.

The most direct train is the Øresunds Train, which will go directly to Østerport Station where you need to get off. This train does not leave that frequently though. Another option is to take the Metro, also from Terminal 3, to Nørreport Station and change there for the S-Train. Catch any northern bound S-train, and get off at the next stop: Østerport Station.

A good site for traveling by train and buses in CPH is www.dsb.dk

From the Airport you need to enter the following: From - Københavns lufthavn (Copenhagen Airport), Kastrup, Terminal 3; To - Østerport station.

Taxi, Amager Øbro Taxi, www.amagerobrotaxi.dk, telephone no. +45 32 51 51 51

Both the Adina hotel and the Unity office are within short walking distance of Østerport station.

5. Schedule

Breakfast, lunch, and dinner will be served in the office on Friday, Saturday, and Sunday. Meal times are:

  • Breakfast: 8:00 - 9:00
  • Lunch: 12:00 - 13:00
  • Dinner: 18:00 - 19:00

We will start the day working at 9 AM every morning and continue on until we feel like stopping.

6. Sponsors

Judging from previous sprints, we'll need about $5000USD in sponsorship for hotel and airfare.

Possible sponsors:

  • Mozilla
  • Facebook

7. Possible Topics

Suggested topics for discussion include:

  • Making Mercurial perform well at scale
  • Areas where we are missing tools/functionality in the every day, real-world, user's workflow and how to fix them. Ideas include:
    • Useful, 'human-readable' view for large merges
    • Integrated stash-oriented workflow (that doesn't rely on buggy or unmaintained 3rd-party extensions)
    • Cheap branching -- bookmarks are probably the best thing we have to offer, but the workflow with them leaves some things to be desired
  • ConsensusMerge

  • what to do about unloved code (fetch, hgk, etc.)
  • tackling code debt
  • short release cycles
  • improve extension development and testing
  • ImprovingCollaboration

7.1. Document Performance Characteristics

What is the complexity (in terms of number of changesets/named branches/heads/tags) of commands such as:

  • hg commit: O(1)?

  • hg log -r 100: O(1)?

  • hg log -b foo: O(number-of-changesets)?

  • hg log -r "branch(foo)": O(number-of-changesets)?

  • hg branches: O(number-of-branches)?

  • hg tags: O(number-of-tags)?

7.2. Extensions in Core

Could we turn some extensions on by default — extensions that most people will want to use anyway?

Put an extension here and let us know if you find it useful. This doesn't mean that we should turn it on by default, but it can help us identify candidates for being included in core:
