Getting your talk accepted: write a convincing talk proposal – Jacinta Richardson

Background

  • On a lot of papers committees
  • LCA, SAGE-AU, OSDC

Pick Conference you want to speak at

  • Some easier to get into than others

  • OSDC 50%
  • YAPC easy
  • OS Bridge – harder
  • OSCON – 30-50% chance
  • everywhere else – medium
  • LCA – really hard. 5x the proposals received than accepted

Speaker rewards

Call for Proposals

  • Not always widely distributed
  • Join mailing lists, watch websites, ask

Write Abstract

  • The hard bit
  • Some confs narrow or wide on talk topics
  • Audience 1 – The programme Comittee
    • Doesn’t know if you are a good speaker
    • Look for link to video of you speaking
    • If no video then assume if writing bad/good then speaking similar
    • Check spelling and writing style
    • Tell a story but not too long
    • Not academia , avoid insane amounts of jargon
    • Paragraphs good. Might only read the first
    • “read first sentence of each paragraph”
  • Audience 2 – The attendees
    • Why your talk?
    • Against other options
    • Good title
    • Skip over – “X for fun and profit” , “making X sexy” , “What I did on my X holidays”
    • 5 or fewer words for title
    • Convincing first paragraph or even the first sentence

Ask for help

  • From usergroups
  • Or people you have met at LCA
  • people on the papers comittee
