Go 1.22, the most recent version of the Go programming language, has been released. It comes with two language changes to for loops: a fix for a longstanding “gotcha” with accidentally sharing loop variables between iterations and adding the ability to range over integer values. There are also additions to the standard library, improved performance, and more. See the release notes for further information.

What is IP fragmentation, why is it important, and do people understand
it? The answer to that last question is “not as well as they think”. This
article will also answer the rest of those
questions and introduce fragquiz, a game that I
wrote to allow players to guess how IP packets will behave when they are
too large for the network. As evidence that IP fragmentation is not
well-understood, a room full of networking experts played fragquiz and got
a score that was
nowhere close to perfect. In addition, I will describe a new algorithm for
fragmentation avoidance, which some colleagues and I
developed, that helped motivate development of fragquiz.

EmacsConf 2023 was, like its
recent predecessors, an online conference with lots of talks about various
aspects of the Emacs
editor—though, of course, it is way more than just an editor. Last year’s
edition was held in early December. One of the
talks that looked interesting was on Emacs
development, which was given live by John Wiegley. In it, he briefly
described some
of the biggest features coming in Emacs 30, which is the next major version
coming for the tool.

Python packaging discussions seem like they often just go around and
around, ending up where they started and recapitulating many of the points that
have come up before. A recent discussion revolves around the pip package installer, as they
often do. The central role that is occupied by pip has both
good points and bad. There is a clear need for something that
can install from the Python Package Index
(PyPI) immediately after Python itself is installed. Whether there
should be additional features, including project management, that come
“inside the box”, as well,
is much less clear—not unlike the question of which project management
“style” should be chosen.

There are many different Python web frameworks, from
nano-frameworks all the way up to the full-stack variety. One that
recently caught my eye is Microdot, the
“impossibly small web framework for Python and MicroPython
“; since
it
targets MicroPython, it is
plausible for running the user
interface of an “internet of things” (IoT) device, for example. Beyond
that, it is Flask-inspired,
which should make it reasonably familiar to many potential web
developers.

Internet pioneer and Network Time Protocol (NTP) inventor Dave Mills has died, as reported by Vint Cerf:
His daughter, Leigh, just sent me the news that Dave passed away peacefully
on January 17, 2024. He was such an iconic element of the early Internet.
Network Time Protocol, the Fuzzball routers of the early NSFNET, INARG
taskforce lead, COMSAT Labs and University of Delaware and so much more.
More information about Mills can be found on his Wikipedia page.

Python’s static-typing feature has come a long way since it was introduced in 2014. Adding type
information to functions has always been—and will remain—optional, but typing
still remains somewhat contentious. There are multiple kinds of
consumers of the information, each with their own needs and
wishes, as well as users of the feature with expectations of their own. That has
led to the formation of a Python typing council
to govern the type system for the language, though, as might be guessed,
there are still grumblings from various quarters.

The new year arrived bearing a new version of Julia, a general-purpose, open-source
programming language
with a focus on high-performance
scientific computing.
Some of Julia’s unusual features are Lisp-inspired
metaprogramming, the ability to examine compiled representations of code in
the REPL or in a “reactive
notebook“, an advanced type and dispatch system, and a sophisticated,
built-in package manager.
Version 1.10 brings big increases in
speed and developer convenience,
especially improvements in code precompilation and loading times. It also
features a new parser written in Julia.
