Like M. Fielder's and M. Hunter's 1986 book, one can find many instances in books, on the World Wide Web, in tutorials, and even on manual pages, of abusing su for dropping superuser privileges and running programs with ordinary user privileges — in cron jobs, /etc/rc scripts, init.d scripts, and even from /etc/inittab. They are all wrong.

Don't abuse su for this purpose. It has never in fact been the function of su, and for the past two decades people have been triggering errors with this abusage. Over the past decade or so, as of 2014, this error has gradually become more and more blatant, going from a few ignorable warning messages in obscure log files to systems that fail to function, but it has in fact been there all of this time.

In March, IPinfo began offering a free, file-based country-level dataset download for IPv4 and IPv6 addresses. This file is the result of over 900 TB of data on BigQuery being synthesized down into a file a few MB in size. The downloads are refreshed daily so changes in IPv4 locations and ownership can be seen with 24-hour granularity.

In this blog post, I'll walk through downloading this dataset as well as looking at some interesting IP address space analysis that it can be used for.

Today, as part of that long term effort to secure the Python ecosystem, we are announcing that every account that maintains any project or organization on PyPI will be required to enable 2FA on their account by the end of 2023.
