Meetup #3

[betatim]

All things related to making the third meetup happen.

Topics

• Cassandra, by Sabine Big data has brought about a lot of new database types such as Hadoop, MongoDB and Cassandra. This talk will focus on Cassandra, the databank, that Facebook invented. As you might guess from this, Cassandra specializes on interactive scalable applications.

  Datamodelling in Cassandra comes with many surprises when you compare it to the traditional RDBMs.

  In this talk Cassandra will be illustrated by walking you through Twissandra, which is a Twitter Clone build with Cassandra and meant to be used as an example. Twitter has the advantage, that its use case is simple and widely known. So we can focus on the data-modeling with Cassandra rather on explaining the use case.

• Bloom filters and other probabilistic data structures, by Tim Head When processing a stream of strings, how do you check if you have seen a string before if your stream is much larger than your memory? Use a bloom filter! I will talk about bloom filters and other probabilistic data structures. We will use genomics as an example application.

Location

TBD. Want to offer a place? Post in this issue.

Date

10, 12, 24, or 26 January 2017?

[betatim]

Any opinions on when? How about 10 or 12 January 2017?

If we decide the date now we might be able to quickly (while we have their attention) find a room at Colab.

@betatim 10, 12 January sounds good!

[Titus-von-Koeller]

Sabine suggested a talk about Cassandra

[betatim]

I'd like to talk about probabilistic data structures (see top comment).

[betatim]

@metaodi would Liip host us again? It seems like 26 Jan is becoming the preferred date.

[betatim]

Two great speakers :) All we need now is a room.

[uweschmitt]

Lets try ETH again. For beer and nibbles we still can go to the ETH cafeteria afterwards.

[betatim]

Thanks!

[betatim]

Any success @uweschmitt or @metaodi?

[uweschmitt]

I applied for the room but did not receive a confimation yet.

[betatim]

I'll keep asking around as well.

[uweschmitt]

Confirmation might take another day..

[uweschmitt]

I got the confirmation for HG E 41 in ETH main building 7 until 10 pm.

[betatim]

Hurray! Every time I go to the HG I get lost and my attempts to find a good map only surfaced screenshots someone made for some conference. Is there no official source?

We should make sure we have one or two people who can access the internet in case speakers need internet. (My eduroam credentials have expired)

[uweschmitt]

here is a map

[uweschmitt]

Wifi for the evening is organized.

[betatim]

Will you be around this time?

[uweschmitt]

Yes, I plan to come.
