Setting up a Zotero workflow on MacOS

Zotero will only allow you to sync your library using either their service (not enough space) or via WebDAV. My Dreamhost backups storage doesn’t support webDAV. I tinkered around with some options (e.g., storagemadeeasy) to turn either my Dreamhost or my NAS shares into WebDAV folders. But, then, I learned that Mac OS doesn’t play […]

It’s taken me a couple of weekends, but I’ve finally gotten all my files moved, various tools installed, and a full range of backup provisions configured. […]

Follow-up to post about LaTeX, etc.

Yesterday, I provided a rough outline of the steps for installing Emacs + AUCTeX in Windows 7. Upon further reflection, I realized a few things about the process. First, most of the documentation for these tools is outdated and/or poorly written (at least for recent versions of Windows). Second, it’s way easier to install this […]

Shameless self-promotion

The editorial assistant for the Journal of Pension Economics and Finance just sent me a copy of this book review. Detailed TOC here. Lots of economists at Big Name Schools there. And, my chapter is mentioned for its contribution. 😀

Doyle, our NAFTA kitty

Earlier this week, we said goodbye to Doyle, our NAFTA kitty. He was almost 17 years old. Doyle was our second pet; we still have our first cat, Pannonica, who is either 17 or 18. We got Doyle in January 1995 from the Austin Humane Society on North 183. I went looking for a cat […]
