SoTWLG Intro to Code Bootcamps 2016 (Roger Nesbitt)
- 1. CODE BOOTCAMPS Making the most of Roger Nesbitt @mogest SUMMER OF TECH 2016
- 4. You have knowledge. You have passion. How do you get a job?
- 5. Myth busting Language overview Developer roles Winning at bootcamps TONIGHT
- 6. Myth busting Language overview Developer roles Winning at bootcamps NEXT
- 7. 1. I know where I’m going with my career 2. I’m competent in the relevant programming language 3. I’ve achieved a relevant qualification 4. I’ve achieved good grades 5. I’m strongly opinionated about “good” and “bad” code 6. I can communicate an idea clearly 7. I can learn new concepts 8. I can work well in a team 9. I can independently write amazing code
- 8. MYTH #5 University prepares you for your working career
- 9. MYTH #4 I need to specialise now to get a good job
- 10. MYTH #3 I’m an 8/10 in Java
- 11. ByPeterCampbell-self-made,NikonD80,GFDL,https:// commons.wikimedia.org/w/index.php?curid=3672205
- 12. You’re probably 2/10. That’s OK!
- 13. MYTH #2 Front-end dev is easy Back-end dev is hard
- 14. MYTH #1 Being a good coder means being good at a programming language
- 15. • Accurately transform real-world ideas and constraints into a language a computer can understand • Factor code to be highly readable and maintainable so changes can be easily made and bugs easily located
- 16. I can work well in a team I can learn new concepts I can communicate an idea clearly I’ve achieved good grades I can independently write amazing code I’m competent in the relevant programming language I’ve achieved a relevant qualification I’m strongly opinionated about “good” and “bad” code I know where I’m going with my career

- 55. WHY, SUMMER OF TECH? WHY???
- 61. PREPARE • Check the resources page https://recruit.summeroftech.co.nz/resources • Install any required packages the day before • Start it up and make sure it goes • Ask on Slack if you’re having trouble
- 62. GO • Attend as many as you can • 101 bootcamps are inspirational • Go to masterclasses if you have 101 knowledge • Prioritise broad over deep
- 63. DURING • Participate in Slack backchannel • Write down three things you want to take away • Chat with the presenter afterwards
- 65. AFTER • Review the “three things” two days later • … and two weeks later • Explore what you’ve learned • Ask questions on Slack • Amazeballs: teach someone what you learned
- 67. BUSTED University prepares you for your working career I need to specialise now to get a good job I’m an 8/10 in Java Front-end dev is easy, back-end dev is hard Good coder == good at a programming language
- 68. LANGUAGES They’re different, but not so different
