Recently someone at work asked for more space to accommodate a rapidly growing table. At the time it had 3.75 billion rows, presented on 143 million pages, and occupying ~1.14TB. Of course we can always throw more disk at a table, but I wanted to see if we could scale this more efficiently than the current linear trend. Sounds like a great job for compression, right?

For my AWS re:Invent talk on BPF Performance Analysis at Netflix, I began with a demo of "BPF superpowers" (aka eBPF). The video is on [youtube] and the demo starts at [0:50] (the sildes are on [slideshare]): I'm demonstrating a tool I developed to turn my laptop's wifi signal strength into audio. I first developed it as this [bpftrace] one-liner: bpftrace -e 'k:__iwl_dbg /str(arg4) == "Rssi %d, TSF %llun"/ { printf("strength: %dn", arg5); }'.

Today we’re heading to Nashville to meet our Senior Manager of Technical Account Management, Lori! She discusses how she works across multiple time zones, her love for working with customers on their integration journeys, and where to get the best lunch in Austin.

The Polyglot Developer

DECEMBER 27, 2019

While working on a bug in one of my projects recently, I found an issue that I could only recreate on an Android device. However, due to some cross-origin resource sharing (CORS) issues on my server, I had to serve my development environment from a changed hostfile that had a specific subdomain of my project. With the ability to use a remote Chrome debugger from your desktop to a mobile device, you can use an emulator and still have your full Chrome debugging capabilities.
