Here’s the software and packages that I use the most for my research.

TL;DR Use a buildpack and set "LDFLAGS=--static" --disable-shared I use Heroku to host most of my websites, and since I mostly use PHP for web development this has worked fine. However, every so often I write an app that calls an external program written in, say, C++. Up until now I've had to host these apps on my own web servers.

Another post inspired by a comment on an earlier one; I had been discussing compounds of the type I.I _n (n=4,6) as possible candidates for hypervalency.

TreeView X, the open source version of TreeView, has been slowly suffering bit rot as C++ compilers and operating systems change. Every so often I'd tweak the code to build on some Linux version or other, but this isn't something I've a lot of time for. Moreover, because of the hassle of rebuilding binaries and source tar balls the updated versions weren't uploaded to the TreeView X web site.

Like benzene, its fully saturated version cyclohexane represents an icon of organic chemistry. By 1890, the structure of planar benzene was pretty much understood, but organic chemistry was still struggling somewhat to fully embrace three rather than two dimensions. A grand-old-man of organic chemistry at the time, Adolf von Baeyer, believed that cyclohexane too was flat, and what he said went.
