ZRAM Boosts Raspberry Pi Performance

Linux is a two-edged sword. On the one hand, there’s so much you can configure. On the other hand, there’s so much you can configure. It is sometimes hard to know just what you should do to get the best performance, especially on a small platform like the Raspberry Pi. [Hayden James] has a suggestion: enable ZRAM and tweak the kernel to match.

My Favourite Secret Weapon – strace

Why strace?

I’m often asked in my technical troubleshooting job to solve problems that development teams can’t solve. Usually these do not involve knowledge of API calls or syntax, rather some kind of insight into what the right tool to use is, and why and how to use it. Probably because they’re not taught in college, developers are often unaware that these tools exist, which is a shame, as playing with them can give a much deeper understanding of what’s going on and ultimately lead to better code.

My favourite secret weapon in this path to understanding is strace.
