Recaps from EmberCamp & JSCamp 2018

Over the weekend, I got to visit Chicago and learn technical and leadership skills from various developers. I will highlight 6 talks that were spectacular. (A special thanks to Trek Glowacki for being a great emcee!)

All talks from EmberCamp will be posted online (note to self: provide links here), so I hope you will check them out.

How to Conduct a Live Code Interview (with 3 Full Problems)

Over the last month, I got to help with hiring developers for the first time. It was fun to use my teaching skills from graduate school and interpersonal skills from Toastmasters to test the candidates’ technical and soft skills. I think the candidates also had a good time interviewing with me.

I believe that live coding, if we do it right, is a great way to test a candidate’s technical and soft skills, and for the candidate to see if we are someone they want to work with and learn from. Unfortunately, it’s hard to find tutorials for doing live code interviews and writing good problems in the first place. It’s even harder to find actual problems because they are kept secret for future use.

In this article, I will explain how to set up a live code interview and how to write good problems based on my experience in teaching. I will reveal the 3 problems that I used in my interviews—yes, I will have to make new ones next time—and analyze why each made a good problem.

Missing Codepoints

As a Saturday project, I unearthed the missing codepoints from Material Icons and made a pull request for Google.

Thanks to a recent update, developers and designers have about 100 additional icons to use in their projects. Unfortunately, they can no longer find the codepoints on the official website, only the icon names. To make matters worse, the codepoints file on Google’s repo hasn’t been updated to show the new icons.

Hello JS World!

Over the past few months, I have converted from a Matlab to a JavaScript user. It’s free, powerful, and in demand. As a result, I will start writing code in JS, maybe occasionally in Matlab. As always, I will write about math.

My recommendations:

  • 3JS: For super awesome graphics
  • D3: For data lovers
  • Ember: For ambitious team projects
  • React + Redux: For easy learning
  • Node: For everything

Happy 2018 everyone!
