Erlang/OTP 22 will be an important release for the
ssl application. We are working on
several new features and improvements such as support for TLS 1.3, some of those are already
on the master branch. This blog post presents the new ssl debug logging built on the new

This blog post looks back on the development of
the SSA-based intermediate representation
from the beginning of this year to the end
of August when the branch was merged.

This blog post continues the exploration of the new SSA-based
intermediate representation through multiple examples. Make
sure to read the Introduction to SSA if you missed it.

This blog post is an introduction to the new SSA-based intermediate
representation that has recently been merged to the
branch in the Erlang/OTP repository. It uses the same
example as in the previous blog post, first looking at the
generated SSA code, and then at some optimizations.

Back after the summer holidays, this blog will now change tracks and
start a series of blog posts about Static Single Assignment (SSA).
This first installment will set the scene for the posts that follow by
looking at the traps and pitfalls one can fall into when trying to
optimize BEAM assembly code.

This blog post is a brief history lesson about the Erlang compiler for
the BEAM machine. To provide some context, there will first be a quick
look at the abstract machines for Erlang.

The BEAM interpreter in erts has been completely re-written in OTP 21.
Most of the instructions have remained the same, but the perl scripts used
to generate the C code have a new implementation. This blog post will look at
some of the optimizations that were possible because of those changes.

This blog post wraps up the exploration of Core Erlang started in the
previous two blog posts. The remaining default Core Erlang
passes are described, followed by a look at how Core Erlang is
represented internally in the compiler.

This blog post continues the exploration of Core Erlang by
looking at some optimizations done by the
compiler pass. The Core Erlang language was introduced in
the previous blog post.

This blog post is the first about the Core Erlang format. In this
blog post, we introduce the Core Erlang format through examples
that compare Erlang code to the corresponding Core Erlang

OTP-21 Release Candidate 1 has just been released. I thought that I would go
through the changes that I am the most excited about. Most likely this will
mostly mean features in erts and the core libraries as those are the
changes that I am the most familiar with.

The memory instrumentation module was rewritten for Erlang/OTP 21 to make it
easier to use. In this post I’ll describe the rationale behind the new features
and how to make use of them.

In this blog post, we will explore the compiler passes that make up
the compiler’s front end.

This is the first of a series of blog posts about the compiler. There
will be blog posts about how the compiler works now, how it might work
in the future, and some historical notes to explain why some things
are what they are. In this blog post I will talk about one of the most
useful options for exploring the compiler, namely the

Erlang/OTP 21 will introduce a completely new IO polling implementation.
This new implementation comes with a new set of tuneable parameters that
can be used to get the most out of your system. This blog post describes
the parameters and attempts to describe what they should be used for.
