Golfing Faster FASTA

After reading Timotimo’s excellent Faster FASTA Please blog post, I wanted to test the performance of some other Perl 6 methods.

IO.slurp.lines

This is my baseline which incorporates Timotimo’s performance improvements to the original solution, somewhat simplified.

force-multi-foci with convex hulls

I have modified the force-multi-foci example to add a convex hull around each cluster of nodes.

I achieved this by using d3.nest() to create a new dataset of clusters containing the nodes in each cluster. Then in the tick() method I create and update the path element for each cluster in this dataset.

Working around OSX legacy Java 1.6 launch dependency for JavaApplicationStub

Fake the existence of 1.6.0 jdk (for whaever reason)

sudo mkdir -p /System/Library/Java/Support/Deploy.bundle
sudo mkdir -p /System/Library/Java/JavaVirtualMachines/1.6.0.jdk

Symlink the JVM library to the required file for JavaApplicationStub.

sudo mkdir -p /Library/Java/JavaVirtualMachines/jdk1.8.0_25.jdk/Contents/Home/bundle/Libraries
sudo ln -s /Library/Java/JavaVirtualMachines/jdk1.8.0_25.jdk/Contents/Home/jre/lib/server/libjvm.dylib \
