Attending

Conference Registration

LAC-19 is a free event open to the pubic: everyone is welcome to attend to the sessions and concerts without registering to the conference. If you'd like to have a badge with your name printed on it, we kindly ask you to send us an e-mail containing the following information:

  • To: lac_AT_linuxaudio_DOT_org
  • Subject: [LAC19 REGISTRATION]
  • First and Last Name
  • Institution
  • E-mail Address

Note: if your paper/performance has been accepted to LAC-19, you don't need to do that.

Club Night

The LAC-19 club night will take place on March 25, 2019 at 7pm in the CCRMA courtyard. It will feature music from members of the community in a "club/party setting". There will a BBQ and soft and alcoholic beverages will be served.

This event is free and anyone can attend to it. However, if you wish to get access to the food and drinks, you'll have to buy a ticket (flat rate: $25) upon check-in at the conference on March 23, 2019. If you cannot be present at the conference that day (and only in that case) and would like to make a reservation to get access to the food and drinks at the LAC-19 club night, please send us an e-mail at lac_AT_linuxaudio_DOT_org, and you'll be able to pay for it directly at the event.

Traveling to LAC-19

By Plane

  • From SFO: you have multiple options to get to Stanford from San Francisco International Airport:
    • Public Transportations: take the BART (see the map) at SFO to the San Bruno (or Milbrae depending on the time you arrive) station, and then change for Caltrain to Palo Alto. Be aware that this solution is FAR from being optimal and we strongly recommend you to opt for one of the following options.
    • Take an UBER (~$45), a Lyft (~$45), or a cab (~$80).
    • Take a shared ride van like SuperShuttle (~$30).
  • From SJC: San Jose International Airport is a nice alternative to SFO (less crowded and closer to Stanford). There is no public transportation option to get from this airport to Stanford: you'll have to use UBER, Lyft or take a cab.

By Train

Good luck! For more information, see the AMTRAK website.

By Car

There's a public parking lot near Tresidder Union, which is very close to the conference venue (Dinkelspiel Auditorium). Parking is free on Saturday and Sunday. Alternatively, you can also park at CCRMA (weekend only, a special permit is needed during weekdays).

Staying at LAC-19

There are dozens of hotels around Stanford (none of them is on campus though). Be aware that Palo Alto is one of the most expensive city in the world :( so don't be surprised by prices. AirBnb is a good alternative. Also, it might be worth staying a bit further away (e.g., Redwood City) and take the Caltrain to get to campus.

Stanford campus is BIG and walking from your hotel to the conference venue might not be an option. Stanford has its own bus network called "Marguerite." It's nice and FREE. Renting a bike during your stay might also be a good option.

Attending to LAC Virtually: Video Streaming and IRC Channel

LAC-19 will be video streamed at the following URL: https://ccrma.stanford.edu/lac19/stream. The easiest way to open this link is to use VLC. Just go in "Media/Open Network Stream."

To interact with presenters during question sessions, we kindly ask you to use the LAC-19 IRC channel: http://webchat.freenode.net/?channels=lac2019.
