FreeBSD and pam_listfile

I’ve discovered unknown terrors while researching and writing PAM Mastery. Well, terrors previously unknown to me, at least. I’m certain that the OpenPAM and Linux-PAM developers are very much aware of them. (I’m also certain that they’re part of the reason DES keeps his hair cut so short, so that he can’t yank it out . . . → Read More: FreeBSD and pam_listfile

I just spammed my customers. Mea culpa.

I’m debugging a problem with a reader who bought books directly from me at The link to download his books isn’t appearing in his account.

As part of this, I noticed that about a fraction of the orders were stuck in the “processing” stage. Customers could get their books by logging in, but the . . . → Read More: I just spammed my customers. Mea culpa.

New novel in print and ebook: Butterfly Stomp Waltz

Some of you have seen this on the mailing list, others on social media. I announce ebook availability to the mailing list and then on social media. Once a fiction book hits print and Amazon ties the two formats together, I blog it.

My new crime thriller novel, Butterfly Stomp Waltz, is out. It’s a . . . → Read More: New novel in print and ebook: Butterfly Stomp Waltz

next talk: “FreeBSD Filesystem Fun” at March semibug

I’m slated to present at the next SemiBUG meeting.

By unpopular demand, I’ll offer “FreeBSD Filesystem Fun,” also known as “odd stuff I learned as I’ve written the FreeBSD storage books.” You’ll get content on UFS, ZFS, unionfs, various memory filesystems, and some of the really odd corners I discovered while writing the book.

Winter Arrivals

Two exciting things happened. First, we have a water heater, kindly provided by the fine folks who sponsored FreeBSD Mastery: Advanced ZFS. A few hours after getting it, my missus declared that she believes the old water heater never worked. At all. She is also highly in favor of water pressure in a shower. Apparently . . . → Read More: Winter Arrivals

Sponsorships and Hot Water

My home is heated by a hot water boiler, a mysterious contraption of tanks and pipes all running to an aluminum-cased burner, the whole thing almost as old as I am. Boilers can last about as long as people, so the age isn’t really an issue. A few months ago, though, one of the mysterious . . . → Read More: Sponsorships and Hot Water
