Today

  • Note the classrooms for Tuesday (CHS 13-105A) and Thursday (CHS 23-105A) are different.

  • HW3 (database, Shiny).

    • deathtime vs dod.

    • No need for intermediate .rds files.

    • Hint: When I knitted my work on HW3 on the teaching server, it uses <1 minute and never uses more than 1% of memory (320MB). If you find yourself using a lot more resource, you must have done something wrong. Keep the mindset: Transform in database, plot in R.

    • You can work either on the teaching server or on your own computer, because we only need to communicate with the BigQuery database in cloud.

  • Database (cont’d).

  • Cloud computing using GCP.

  • Want to challenge yourself? April 9th: Citadel West Coast Regional Datathon. Apply here. If selected, travel cost is covered.

Prizes: $15,000 + eligibility to interview at Citadel

Datathons are world’s #1 virtual data science competitions. This is a great opportunity for students to work on challenging problems while engaging with real-world data in a competitive, team-based setting.

For students in schools not in the Bay Area, transportation and accommodation (if need be) expenses will be fully covered.
