[Bloat] Seen in passing: mention of Valve's networking scheme and RFC 5348

This is  not an initiative I know about, but it mentions Reno and it's 
inability to use SACK, so it sounds at first hearing to be another dumb 
gamer thing. Opinions, anyone?

 1. Valve's Networking Code
    <https://github.com/ValveSoftware/GameNetworkingSockets> -- /a basic
    transport layer for games. The features are: connection-oriented
    protocol (like TCP)...but message-oriented instead of
    stream-oriented; mix of reliable and unreliable messages; messages
    can be larger than underlying MTU, the protocol performs
    fragmentation and reassembly, and retransmission for reliable;
    bandwidth estimation based on TCP-friendly rate control (RFC 5348);
    encryption; AES per packet, Ed25519 crypto for key exchange and cert
    signatures; the details for shared key derivation and per-packet IV
    are based on Google QUIC; tools for simulating loss and detailed
    stats measurement./

 3. The Problem With Voting
    -- I don't agree with all of the analysis, but the proposed
    techniques are interesting. I did like the term "lazy consensus"
    /where consensus is assumed to be the default state (i.e., “default
    to yes”). The underlying theory is that most proposals are not
    interesting enough to discuss. But if anyone does object, a
    consensus seeking process begins./ (via Daniel Bachhuber
 4. pix2code <https://arxiv.org/abs/1705.07962> -- open source
    <https://github.com/tonybeltramelli/pix2code> code that generates
    Android, iOS, and web source code for a UI from just a photo. It's
    not coming for your job any time soon (/over 77% of accuracy/), but
    it's still a nifty idea. (via Two Minute Papers <http://bit.ly/2uGxWu3>)
