The standard unix password manager you never heard of

Recently I switched my work environment from OS X to Ubuntu (a post on that project is in the works). For years I’ve been using the standard Apple Keychain app, which has several points in its favor: it’s included with the OS, it integrates well with a lot of applications, and is not trying to “freemium” me into a paid tier. However, it’s OS X only, which meant I had to find something new.

Keeping emacs backup files tidy

In the shell, emacs is my editor of choice. However, it has one default behavior that has gotten in the way more often than it has helped – automatic generation of backup files in the same directory as the original. Emacs is great for making quick edits to files on the web server. But I don’t want or need all those *~ files sitting around. The material is all in version control, so I can already revert to any point in history.

A tiny little dpaste.com API

When I created dpaste, I tried to make it both a simple browser-based tool and a simple RESTful API. With very little work you could write a script that created a new paste item with a single POST. Over the life of the site a few people have discovered and played with that “secret” API. I’ve now made it a bit more official. The new API has its own URL (versioned, even!

History lesson

This has been going around – give people a peek at what commands you run most often. I ran this on my server, where I spend most of my shell time: > history|awk '{a[$2]++} END{for(i in a){printf "%5d\t%s\n",a[i],i}}'|sort -rn|head 103 hg 81 cd 67 ll 29 ./manage.py 23 ab 21 re-ap 17 hgup 14 svn 13 cat 12 ls Notes: Mercurial has pushed my use of Subversion way down.

The anti-desktop movement

An opinionated minority of advanced computer users are rebelling against the WIMP (windows, icons, menus, pointers) model of HCI. They are developing and promoting alternative interfaces (typically desiigned to work with unix-based systems) that embody their opinions. I haven’t used any of these yet, but here are the ones I keep encountering references to: Ion Ratpoison Orion StumpWM Most if not all of these credit the terminal-only GNU Screen (a program I do use) with inspiration.

What is the iPhone running, really?

In case you missed it, Apple has a new product. You can’t, you know, buy it or anything just yet – that’ll be about six months. And $500, please. While you wait you can compare it to the competition. They claim that it runs OS X. Hm. I can imagine there’s a BSD kernel (running on what processor I don’t know), QuickTime, WebKit… but really, how much of the stuff in the standard OS X architecture diagram is actually going to be in that phone?
