Over the past years, I have tried to capitalize on my findings. What I have
lacked in regularity I made up for in subject exoticism.

* About Coq
-:PROPERTIES:
-:CUSTOM_ID: coq
-:END:
-
-Coq is a formal proof management system which provides a pure functional
-language with nice dependent types together with an environment for writing
-machine-checked proofs.
-
-- [[./posts/StronglySpecifiedFunctions.org][A Series on Strongly-Specified Funcions in Coq]] ::
- Using dependent types and the ~Prop~ sort, it becomes possible to specify
- functions whose arguments and results are constrained by properties.
- Using such a “strongly-specified” function requires to provide a proof that
- the supplied arguments satisfy the expected properties, and allows for soundly
- assuming the results are correct too. However, implementing dependently-typed
- functions can be challenging.
-
-- [[./posts/Ltac.org][A Series on Ltac]] ::
- Ltac is the “tactic language” of Coq. It is commonly advertised as the common
- approach to write proofs, which tends to bias how it is introduced to new Coq
- users (/e.g./, in Master courses). In this series, we present Ltac as the
- metaprogramming tool it is, since fundamentally it is an imperative language
- which allows for constructing Coq terms interactively and incrementally.
-
-- [[./posts/RewritingInCoq.html][Rewriting in Coq]] ::
- The ~rewrite~ tactics are really useful, since they are not limited to the Coq
- built-in equality relation.
+ :PROPERTIES:
+ :CUSTOM_ID: coq
+ :END:
-- [[./posts/ClightIntroduction.html][A Study of Clight and its Semantics]] ::
- Clight is a “simplified” C AST used by CompCert, the certified C compiler. In
- this write-up, we prove a straighforward functional property of a small C
- function, as an exercise to discover the Clight semantics.
-
-- [[./posts/AlgebraicDatatypes.html][Proving Algebraic Datatypes are “Algebraic”]] ::
- The set of types which can be defined in a language together with ~+~ and ~*~
- form an “algebraic structure” in the mathematical sense, hence the name. It
- means the definitions of ~+~ and ~*~ have to satisfy properties such as
- commutativity or the existence of neutral elements.
-
-- [[./posts/Coqffi.org][A Series on ~coqffi~]] ::
- ~coqffi~ generates Coq FFI modules from compiled OCaml interface
- modules (~.cmi~). In practice, it greatly reduces the hassle to
- together OCaml and Coq modules within the same codebase, especially
- when used together with the ~dune~ build system.

* About Haskell
-Haskell is a pure, lazy, functional programming language with a very expressive
-type system.
-
-- [[./posts/ExtensibleTypeSafeErrorHandling.html][Extensible, Type-Safe Error Handling In Haskell]] ::
- Ever heard of “extensible effects?” By applying the same principle, but for
- error handling, the result is nice, type-safe API for Haskell, with a lot of
- GHC magic under the hood.
+ #+include: ./haskell.org
* Miscellaneous
-- [[./posts/DiscoveringCommonLisp.html][Discovering Common Lisp with ~trivial-gamekit~]] ::
- Common Lisp is a venerable programming languages like no other I know. From
- the creation of a Lisp package up to the creation of a standalone executable,
- we explore the shore of this strange beast.
