PCB prototype manufacturing review – 3-way shoot-out

Disclaimer: PCBWay provided free PCBs for this review. No other compensation was provided. PCBWay did not request nor receive favourable treatment.

Laying out the board in KiCAD.

The following is a 3-way shoot-out review between 3 PCB manufacturers: PCBWay and JLCPCB in China, and Oshpark in the US. I uploaded the same Gerber files to each of them. I’ve reviewed both the order process and the finished product. You can download my KiCAD files (warning: I used the development nightly version) from Github: https://github.com/rockola/stomp-breakout/

FizzBuzz in Common Lisp

FizzBuzz is a famous recruitment interview question for programmers.

Write a program that prints the numbers from 1 to 100. But for multiples of three, print “Fizz” instead of the number and for the multiples of five, print “Buzz”. For numbers which are multiples of both three and five, print “FizzBuzz”.

I imagine it can be used to weed out the ones who lied about everything on their application, since it is not exactly brain science nor rocket surgery. Continue reading “FizzBuzz in Common Lisp”

Gaussian process classification for prediction of in-hospital mortality among preterm infants

I admit, the title is a bit of a mouthful. It’s the title of an upcoming article in Neurocomputing by Rinta-Koski, Särkkä, Hollmén, Leskinen, and Andersson – also what I hope to be the last remaining piece of the puzzle (not counting the summary) that is my thesis.  Continue reading “Gaussian process classification for prediction of in-hospital mortality among preterm infants”
