Awesome Talk : LISA17 – “Don’t You Know Who I Am?!” The Danger of Celebrity in Tech

This is the first post, in what hopefully will turn into a series of posts, highlighting awesome talks that are freely available. There is a lot of great content out there, both inspirational and funny, and I’ll try to publish my favorites when I find them.

So here is the first one!

John Nicholson shared this awesome talk by Corey Quinn from LISA17, which should be mandatory for anyone attending conferences, or talks in general. Not only does it dive into the culture of asking questions when attending a talk, but also has lots of good information for speakers as well. Trust me, this is ~44 minutes very well spent.

Mass Converting .svg to .png on macOS

When playing around with Royal TSX I needed to mass convert the VMware Clarity .svg files to .png files that I could use as icons in Royal TSX.

After trying a series of different approaches, I ended up with using rsvg-convert from libRSVG. In order to get rsvg-convert installed on my MacBook, I turned to HomeBrew.

HomeBrew, which calls itself The missing package manager for macOS is in my opinion essential for any macOS user. If you are missing a command or utility, chances are that HomeBrew has you covered.

Mass Converting:

Once you have HomeBrew installed, you’re pretty much ready to go by running the following command in Terminal:

brew install librsvg

This installs the libRSVG formulae, and all it’s dependencies, and makes rsvg-convert available.

Once libRSVG installed locally, you can mass-convert .svg files by running the following command in your terminal of choice.

for i in *; do rsvg-convert $i -o `echo $i | sed -e 's/svg$/png/'`; done

This loops through every .svg file in the current directory, and creates .png versions of them, for usage elsewhere.
