-* Compiler bootstrapping
-  This section contains notes about compiler bootstrapping, the
-  history thereof, which compilers need it - and so on:
-
-** C
-
-** Haskell
-   - self-hosted compiler (GHC)
-
-** Common Lisp
-   CL is fairly interesting in this space because it is a language
-   that is defined via an ANSI standard that compiler implementations
-   normally actually follow!
-
-   CL has several ecosystem components that focus on making
-   abstracting away implementation-specific calls and if a self-hosted
-   compiler is written in CL using those components it can be
-   cross-bootstrapped.
-
-** Python
-
-* A note on runtimes
-  Sometimes the compiler just isn't enough ...
-
-** LLVM
-** JVM

-
-* Slide thoughts:
-  1. Hardware trust has been discussed here a bunch, most recently
-     during the puri.sm talk. Hardware trust is important, as we see
-     with IME, but it's striking that people often take a leap to "I'm
-     now on my trusted Debian with free software".
-
-     Unless you built it yourself from scratch (Spoiler: you haven't)
-     you're placing trust in what is basically foreign binary blobs.
-
-     Agenda: Implications/attack vectors of this, state of the chicken
-     & egg, the topic of reproducibility, what can you do? (Nix!)
-
-  2. Chicken-and-egg issue
-
-     It's an important milestone for a language to become self-hosted:
-     You begin doing a kind of dogfeeding, you begin to enforce
-     reliability & consistency guarantees to avoid having to redo your
-     own codebase constantly and so on.
-
-     However, the implication is now that you need your own compiler
-     to compile itself.
-
-     Common examples:
-     - C/C++ compilers needed to build C/C++ compilers:
-
-       GCC 4.7 was the last version of GCC that could be built with a
-       standard C-compiler, nowadays it is mostly written in C++.
-
-       Certain versions of GCC can be built with LLVM/Clang.
-
-       Clang/LLVM can be compiled by itself and also GCC.
-
-     - Rust was originally written in OCAML but moved to being
-       self-hosted in 2011. Currently rustc-releases are always built
-       with a copy of the previous release.
-
-       It's relatively new so we can build the chain all the way.
-
-     Notable exceptions: Some popular languages are not self-hosted,
-     for example Clojure. Languages also have runtimes, which may be
-     written in something else (e.g. Haskell -> C runtime)
-* How to help:
-  Most of this advice is about reproducible builds, not bootstrapping,
-  as that is a much harder project.
-
-  - fix reproducibility issues listed in Debian's issue tracker (focus
-    on non-Debian specific ones though)
-  - experiment with NixOS / GuixSD to get a better grasp on the
-    problem space of reproducibility
-
-  If you want to contribute to bootstrapping, look at
-  bootstrappable.org and their wiki. Several initiatives such as MES
-  could need help!
