I am a principle software engineer that specializes in Internet and web protocols like HTTP/2, HTTP/3, QUIC, and WebTransport.

I previously worked at Cloudflare on the Protocols team who own Layer 4 and Layer 7 termination and proxying, helping to improve the security and performance of Internet-facing services. In this role I focused on the application-layer enhancements made possible by leading edge developments in the underpinning protocols. As part of that I co-maintained quiche, an open source library for HTTP/3 and QUIC written in Rust.

I produced this poster as part of a university module entitled Communicating Science.

The poster was targeted toward GCSE and A-Level students hence the bold design and colours to help improve attraction and interest.

I originally uploaded this poster to a past incarnation of www.lucaspardue.co.uk and I was partially surprised to find relinked or reblogged on several sites concerning infographics, physics etc. The poster is linked to by a Rutgers assignment page concerning Information Design and I still seem to have traffic coming from there, so for all the visitors that have been hunting for the poster, here it is.

Temporary page for testing. Not linked from any menu and attempted to be hidden from the bots ;-)

The core HTTP specifications don’t define their own means of providing integrity. Although “hop-by-hop” protocols underneath HTTP, such as TLS or QUIC, provide integrity for HTTP message transactions, it isn’t enough. HTTP powers massively distributed systems where intermediaries (aka proxies) are first-class citizens. Coupled with that are the powerful semantics of HTTP resources and representations.

The following is a collection of openly available publications beyond this blog that I have authored or co-authored.

• RFC 9218 Extensible Prioritization Scheme for HTTP
• RFC 9297 HTTP Datagrams and the Capsule Protocol
• RFC 9530 Digest Fields

Adopted Internet-Drafts

In-progress documents being standardized in the IETF:

• Maintaining Protocols Using Grease and Variability
• Resumable Uploads for HTTP
• qlog: Structured Logging for Network Protocols

• HTTP/3 qlog event definitions
• QMux
• HTTP/3 over QMux
• HTTP Unencoded Digest

Other Internet-Drafts

I.e., abandoned or expired documents:

SpotifyStatusApplet was broken by a Spotify API change made in Q3 2018. All previous downloads have been removed from this site. I switched to a Logitech G915 TKL in 2021, so I no longer have any plans to work on applets.

SpotifyStatusApplet - an LCD applet for the Logitech Gaming keyboard family.

From version 1.2, the field titles (Track, Album and Artist) can be toggled on/off by pressing “soft key 1”, the first key underneath the LCD on most models.
