Compress all the images!

One advantage that static sites, such as those built by Hugo, provide is fast loading times. Because there is no processing to be done, no server side rendering, no database lookups, loading times are just as fast as you can serve the files that make up the page. This means that bandwidth becomes the primary bottleneck, which incidentally is one of the factors used by Google to calculate your search ranking.

Migrating from Ghost to Hugo

So I recently migrated this site from Ghost to Hugo after reading a nice article about the Hugo in Linux Voice #20 (funnily enough, the same issue also features an article about Ghost).

Ipython is more descriptive that something is wrong, but if you’re in the habit of mostly using python as a quick calculator, you might never notice: If you’re using Miniconda then just do: conda install ncurses readline And ↑ should work:

Nvidia G-Sync and Linux

After getting a fancy new monitor with G-Sync support, I was eager to try it out in my Linux gaming setup. While Nvidia fully supports G-Sync in their Linux drivers, it turns out that other components of the system can get in the way. As explained by a post on the Nvidia forums: For G-SYNC to work, the application has to be able to flip and the symptoms you’re describing here sound like it’s not able to flip in your configuration.
