Programming — Principles and Practice Using C++, 2nd edition
I got my copy of “Programming — Principles and Practice Using C++”, second edition, today. My copy is of the third printing, dated June 2015, so it’s a pretty recent printing. I’m not teaching programming nor C++ at my school, although I used to. My job is simply to be the school’s system administrator, but […]

The strange combination of FreeBSD/i386, stable/10, OpenSSL from ports, optimized assembly code, Dell PowerEdge 1950, Intel Xeon X5450@3.00GHz, and BIOS 2.5.0, resulted in core dumps for all applications linked with OpenSSL from ports.

Finally, a CygWin package for mosh 1.2.5 is available. Run to your nearest CygWin mirror and update your system. If you’re new to CygWin, I advise you to select mosh, Perl, and OpenSSH, in addition to the base set of packages selected for you.

mosh 1.2.5 is out, but not yet available as a CygWin package. I decided I should upgrade my CygWin installation in preparation. That proved not so fruitful. The new mintty 2.1.1 crashed with the infamous STATUS_ACCESS_VIOLATION stack dump. I’m a bit surprised there’s no mintty-debuginfo package as it would make it easier to know what’s […]

Revision 392534 of the FreeBSD ports tree added TeX Live 2015. In the process, print/texlive-infra was replaced with print/texlive-tlmgr. If you already have TeX Live 2014 installed, e.g. print/texlive-full, then print/texlive-base conflicts with print/texlive-texmf and vice versa.

Microsoft is pretty sneaky. They camouflage their Windows 10 downloader, KB3035583, as a recommended Windows 7 update with no indication of what good this update does. Only by clicking on the first link is its true intention revealed. As a contrast, the dreaded KB976002 browser choice update was well marked with its intention even in […]

I had great fun watching the YouTube videos for “The Erlang Master Classes”, at The University of Kent, and typing Erlang code along the way. Go and see for yourself at http://www.kent.ac.uk/elearning/themes/masterclasses.html. Here are some thoughts from prof. Simon Thompson, http://profsjt.blogspot.co.uk/2015/06/the-erlang-mini-mooc-pilot-what-have-we.html.

This is an exercise I made, just to remind myself of how snapshots and clones work in ZFS. Also, how to properly get rid of them when you’re short of diskspace, or the dataset listing is too long, etc. First, we have the shell script that demonstrates the rise and fall of the initial dataset, […]

I bought the ebook edition of FreeBSD Mastery: ZFS this June. While the authors’ intentions are good, the 2015-05-21 edition has some errors and mistakes. The table below is nothing more than an unofficial errata of said book. Beware, what you find below might be due to my lack of understanding FreeBSD, ZFS, or the […]
