Continuing our posts from the last time, we wanted to share a few more weekliest links from the reading lists of Chartbeat engineers:

• Optimizing a system for performance or scalability or reliability is something we all eventually have to face, but we are always warned about the ills of pre-mature optimization. In contrast, the Mature Optimization Handbook [pdf] is a quick read with lots of wisdom around striking this balance.
• Since no blog or forum these days is complete without a few — preferably contrasting — strong opinions about the Julia programming language, we think Evan Miller’s Why I’m betting on Julia is worth another read. We don’t have anything in production running Julia yet, but some recent hackweek work has sparked some interest.
• Finally, we wanted to round out this week with a post about the Evolution of Open Redirect Vulnerability, a reminder of how something as seemingly simple as incorrect string parsing can be exploited for evil.

Happy Friday!
