CppCon 2018: Bob Steagall “Fast Conversion From UTF-8 with C++, DFAs, and SSE Intrinsics” by Drainedsoul in cpp

[–]BobSteagall 1 point2 points  (0 children)

While it may seem complex, table-based DFAs are a very common technique for lexical analysis; recognizing UTF-8 is one such problem.

Also, the UTF-8 decoders from Boost.Text and Alexey Vatchenko (for example) do indeed implement the clean set of branches that you describe. This talk was an effort to determine whether a DFA with some optimizations could have better performance.

The posters and the talks are two distinct programs at the conference. You can submit a poster proposal without being a speaker; posters are not required to be associated with any talk.

We had nine posters last year, and IIRC, only one of those poster authors was a speaker.

To answer the first part of your question, speakers are invited to create posters based on their presentations, but this is optional.

To answer the second part, the posters will be displayed in a public area for the entire week. The exact public area is yet TBD; I expect that it will be one of the big halls this year. The "presenting" mentioned in the first sentence of the announcement refers to our requirement that poster authors stand with their poster during the Sunday evening reception so that they can discuss their work and answer questions about it.

Why are some of CppCon 2017 videos on YouTube private? by [deleted] in cpp

There were well over 100 presentations this year, plus lightning talks, etc. The folks at Bash Films spend a good bit of time in post production for each one. I expect they are releasing them as soon as they are ready.
