Just over ten years ago, I decided to establish a blog about TeX matters.
After a bit of consideration and searching, I found that texdev.net was
available, and decided to call the blog Some TeX
Developments.

TeX does not include any ‘native’ support for floating point calculations, but that has not stopped lots of (La)TeX users wanting to do sums (and more complicated things) in their document. As TeX is Turing complete, it’s not a surprise that there are several ways to implement calculations. For end users, the differences between these are not important: what is key is what to use. Here, I’ll give a bit of background, look at the various possibilities, then move on to give a recommendation.

In parallel with work on the
\expanded primitive, I’ve been working
recently on bringing the ‘utility’ primitives in
XeTeX into line with those in
pdfTeX, pTeX and upTeX.

In recent years, development of pdfTeX has been very limited, with the v1.40
branch now being around for over 10 years. However, in the past there were
plans for a v1.50 branch, and some code was actually written. One primitive
that was fully coded-up at that time was \expanded. The idea of this is
pretty simple: it carries out full expansion like \message (and almost
like \edef), but it is still expandable. For example, try

I’ve been writing Some TeX Developments for ten years now, starting off on WordPress.com before moving to a self-hosted WordPress set up. All of this time, I’ve stuck with WordPress as it’s a very powerful and flexible system. However, it’s got some downsides too. In particular, as it is dynamic, database-driven, system, the pages are created each time someone requests them. That’s great for things like supporting comments, but it means there’s a non-trivial amount of work done each time someone views a page. That turns into a real cost when you are paying for your own hosting. My most recent hosts were really good for support, but I needed enough CPU cycles to push me into the ‘non-trivial’ cost bracket. At the same time, a dynamic site means that there’s always a security risk.

Members of TUG might have seen a survey from the Board asking about the status of TUGboat. To date, the journal issues have been available online one year after publications. The Board were interested in how going open-access would affect the number of members.

The final day of TUG2018 followed the conference banquet, which of course meant that there were a few tired (or missing!) delegates.

The second day of TUG2018 picked up with a few announcements for those us here at IMPA, before we moved on to the business end.

Most of the foreign delegates for TUG2018 met up by last night at the conference hotel, and chats over breakfast continued. Then it was down to the minibus to head to the venue, IMPA.

The TUG2018 meeting starts tomorrow in Rio de Janerio, Brazil, and the delegates have begun to collect together (many of us are staying at the Everest Rio Hotel). I’ll be trying to write up notes each day to summarise the talks, discussions, etc., but you’ll also be able to watch live. There’s also a chat room on TeX StackExchange dedicated to the meeting.
