By Alok Tiagi , Hariharan Ananthakrishnan , Ivan Porto Carrero and Keerti Lakshminarayan Netflix has developed a network observability sidecar called Flow Exporter that uses eBPF tracepoints to capture TCP flows at near real time. At much less than 1% of CPU and memory on the instance, this highly performant sidecar provides flow data at scale for network insight.

Dynatrace news. AWS Lambda is the fastest growing technology for serverless workloads and helps developers innovate faster. It removes the burden of managing underlying infrastructure and is broadly adopted for cloud-native application environments. But serverless functions don’t exist in a vacuum. It’s critical that you understand how they impact your customer-facing web applications, mobile apps, or APIs and how they interact with other functions, services, and classic technology stacks.

These are rough notes. I run the Slack messaging application on Ubuntu Linux, and it recently started mysteriously crashing. I'd Alt-Tab and find it was no longer there. No error message, no dialog, just gone. It usually happened when locking and unlocking the screen. These are rough notes for how I debugged it, in case it's useful for someone searching on this topic.

Bucketizing date and time data involves organizing data in groups representing fixed intervals of time for analytical purposes. Often the input is time series data stored in a table where the rows represent measurements taken at regular time intervals. For example, the measurements could be temperature and humidity readings taken every 5 minutes, and you want to group the data using hourly buckets and compute aggregates like average per hour.

Client-side A/B testing has been a performance loving developer’s worst friend for years. The way it works is you load in some JavaScript (typically from a third-party domain), and that JavaScript runs, applying the experiments you’re running for any given situation. Since those experiments usually involve changing the display of the page in some way, these scripts are typically either loaded as blocking JavaScript (meaning nothing happens until the JavaScript arrives and gets execut
