Speaking at DevReach 2017

I’ll be delivering two talks (about HTTPS and Fiddler) at the DevReach 2017 conference in Sofia, Bulgaria. It’ll be fun to get back to Europe, and I’m looking forward to seeing old friends and colleagues. Hope to see some of y’all there! -Eric

Working with “Big Data” in .NET

For simplicity (and because I didn’t know any better at the time), Fiddler uses plain public byte[] array fields to represent the request and response bodies. This makes working with the body data trivial for authors of extensions and FiddlerScript, but it also creates significant shortcomings. Using fields rather than properties improves performance in some scenarios,Continue reading “Working with “Big Data” in .NET”

Fiddler And LINQ

Since moving to Google at the beginning of 2016, I’ve gained some perspective about my work on Fiddler over the prior 12+ years. Mostly, I’m happy about what I accomplished, although I’m a bit awed about how much work I put into it, and how big my “little side project” turned out to be. It’sContinue reading “Fiddler And LINQ”

Finding Image Bloat In Binary Files

I’ve previously talked about using PNGDistill to optimize batches of images, but in today’s quick post, I’d like to show how you can use the tool to check whether images in your software binaries are well optimized. For instance, consider Chrome. Chrome uses a lot of PNGs, all mashed together a single resources.pak file. Tip:Continue reading “Finding Image Bloat In Binary Files”

Chrome Deprecates Subject CN Matching

If you’re using a Self-Signed certificate for your HTTPS server, a deprecation coming to Chrome may affect your workflow. Chrome 58 will require [why?] that certificates specify the hostname(s) to which they apply in the SubjectAltName field; values in the Subject field will be ignored. This follows a similar change in Firefox 48. If impacted,Continue reading “Chrome Deprecates Subject CN Matching”
