-## Making Technology More Inclusive Through Papercraft and Sound
-
-By Andrew Huang.
-
-I like how the talk goes over a range of cross-domain topics:
-
-- high-level motivations
-
-Improving inclusiveness is necessary to make open-source actually
-empower people; right now a very small subset of the population is
-computer-savvy enough to take advantage of it. If the situation does
-not improve, a handful of developers will hold a lot of power over
-lots of alienated users, and lawmakers may resort to "preposterous"
-solutions to attempt to regain control, e.g. license bonds for
-software developments.
-
-- Kickstarter campaign management
-- design choices & rationale
- - "China-ready"
- - "patience of a child" constraint
-- gory hardware details
-- the end result

-## QUIC: Replacing TCP for the Web
-
-By Jana Iyengar.
-
-Starts by introducing impressive application performance improvements,
-although where were those measured? E.g. rural areas?
-
-Advantage that can already be inferred from the layer view: QUIC needs
-fewer handshakes than TCP+TLS.
-
-Achieves 0-RTT when the server's cryptographic credentials are known.
-
-Supports "stream multiplexing": the upper layer (e.g. HTTP) can
-transfer multiple objects independently in a single connection.
-Losing part of one object does not block the others: retransmission is
-managed at the stream level, not at the connection level.
-
-On top of UDP: allows userspace (Chrome) implementation.
-
-> If you think of layers as a set of functions, things that you want
-> done, UDP is not a transport protocol.
-
-I.e. UDP does not provide reliability, same-order delivery…
-
-Jana was "in the SCTP bandwagon".
-
-They actually have *better performance improvements* for *bigger
-latencies*? Nice.
-
-> § QUIC improvements by country
-
-👏
-
-(Of course the end goal is probably to make sure regions with poor
-connections do not miss out on the adfest; still, these remain welcome
-technical improvements)
-
-Transport headers are encrypted to prevent "middlebox ossification".
-They left a *single* byte unencrypted (the flags byte): this allowed
-middleboxes to observe that it kinda had the same value on most
-connections, assume that this was a "nominal" value, and block traffic
-when this value differed.
-
-## You Can't Unit Test C, Right?
-
-By Benno Rice.
-
-- Mentions [Check](https://libcheck.github.io/check/) and
- [Kyua](https://github.com/jmmv/kyua).
-- Factor your boilerplate into libraries, especially the ugly hacks.
-- Keep `main` small so that you don't need to test it so much.

-## Changing the world through (fan-)fiction
-
-By Paul Fenwick.
-
-Reading fiction is a convenient way to get us to think through
-concepts we had not considered before. By re-purposing a familiar
-setting, *fan*fiction lowers the barrier to entry to the writing
-exercise: it makes it easier for the writer to get their point across
-and to reach their audience.
-
-Some recommendations:
-
-- The Last Ringbearer
-- [My Little Pony: Friendship is Optimal]
-- [Harry Potter and the Methods of Rationality]
-
-Our media teaches us what is normal. Hence fiction opens up ways to
-improve the status quo by acquainting us to new ideas.
-
-Another recommendation: Steven Universe.
-
-Mainstream and folklore stories feature a fair amount of unhealthy
-relationships; this is problematic because repeated exposure helps
-normalization[^I find that SMBC is a positive example of this effect:
-it regularly (and, AFAICT, fairly randomly) features gay couples in
-comics where the joke is *not* about homosexuality].
-
-In Japan, doujinshi is considered normal and "adding value to the
-brand", whereas similar things are flagged as "copyright infringement"
-in other countries.

-## Lessons from three years of volunteering to teach students code
-
-By David Tulloh.
-
-Takeways:
-
-1. Volunteering in schools is easy and fun.
-2. We should care about what is taught in schools.
-3. We should get involved and support schools teaching IT.
-
-CSIRO: Australian program to get professional developers to teach in
-schools.
-
-[Pixees](https://pixees.fr/) seems to be a French equivalent.
-
-Tried to move students from "programmers" to "developers" by evoking:
-
-- automated testing
-- version control
-- bug tracking
-- code review
-
-An audience member noted that while programs ala CSIRO are helpful,
-this should be organized at the government policy level.
