Reliability engineering teams at Uber build the tools, libraries, and infrastructure that enable engineers to operate our thousands of microservices reliably at scale. At its essence, reliability engineering boils down to actively preventing outages that affect the mean time between … The post Using Machine Learning to Ensure the Capacity Safety of Individual Microservices appeared first on Uber Engineering Blog.

If you use React and need to display large lists of data efficiently , you may be familiar with react-virtualized. It's a windowing library by Brian Vaughn that renders only the items currently visible in a list (within a scrolling "viewport"). This means you don't need to pay the cost of thousands of rows of data being rendered at once.

In this blog post, I want to share a case we worked on a few days ago. I’ll show you how we approached the resolution of a MySQL performance issue and used Percona Monitoring and Management PMM to support troubleshooting. The customer had noticed a linear high CPU usage in one of their MySQL instances and was not able to figure out why as there was no much traffic hitting the app.

Occasionally I hear some chatter about performance budgets “not working.” And, to be fair, I have seen companies who adopt a budget and then are unable to make meaningful improvements towards that goal. Over time those ineffective budgets get pushed to the sideline where they accumulate dust before being forgotten about altogether. It’s not really about the performance budget, though.

For this experiment I am using Postgres v11 on Linux 3.10 kernel. The goal was to see what gains can be made from using hugepages. I use the “built in” benchmark pgbench to run a simple set of queries. Since I am interested in only the gains from hugepages I chose to use the “-S” parameter to pgbench which means perform only the “select” statements.

Following up on my post about the benefits of speedy meetings , here’s a collection of tips that I think improve calendaring etiquette. Some of these are personal preference, but all of them feel like genuine improvements to me in real life. Only One Calendar Actually Exists. Calendar technology and apps just aren’t universally multi-calendar-friendly.
