http://darkness.codefu.org/wordpress Technical adventures and blabbering Thu, 27 Dec 2007 02:05:16 +0000 http://backend.userland.com/rss092 en I’ve been working in Plone, so I’ve seen zope.component. I’m also thinking of making a (potentially) networked game in Python, and for that I was looking at things like Twisted and Kamaelia. Unsurprisingly, I’m not really satisfied with any of these. Let me try to articulate what I’m looking for when I say “component system” (perhaps ... http://darkness.codefu.org/wordpress/2007/12/26/295 Fedora 7’s new Firewire stuff might not be totally together: when I plugged in my DV cam, I couldn’t read the device except (I guess?) as root. (Kino also kept crashing, and I ended up just using dvgrab.) Apparent side-effect of running sudo kino: some shared memory used by dmix became owned by ... http://darkness.codefu.org/wordpress/2007/12/25/293 I’ve got some poorly recorded MP3s of people speaking. I want to try to make them a little easier to hear. In Windows I’d reach for Sound Forge. How about in Linux? Search Google for “sound forge equivalent for Linux.” Find several references to “Wave Forge.” Find “Wave Forge” hasn’t been updated this ... http://darkness.codefu.org/wordpress/2007/12/15/292 I had to restore some Maildir-style mailboxes from an old Courier IMAP server to a newish Cyrus IMAP server. There’s not much to it, and this is well documented elsewhere, but basically you can copy the files in (I don’t know if they need to be named like 123. like Cyrus does by ... http://darkness.codefu.org/wordpress/2007/11/17/291 Problem: sieve rules like redirect (A.K.A. forward) don’t work on CentOS 5. You see things in the logs like: Oct 29 17:15:52 gateway lmtpunix[26948]: sieve runtime error for someone@example.com id <blahlblahasdlahd@as987da97da987ads7>: Vacation: Sendmail process terminated normally, exit status 75 Nov 1 00:47:10 gateway lmtpunix[30206]: FATAL: couldn't exec() sendmail Explanation: SELinux is preventing Cyrus from ... http://darkness.codefu.org/wordpress/2007/11/01/290 A client wants to know about possible “calendaring solutions,” things like a Notes or an Exchange, but presumably cheap/free. In this case, these guys aren’t currently Outlook/Exchange users, and obviously Exchange doesn’t fit the definition of “cheap,” so I don’t have to contend with that. Here I’m referring to the difficulty switching away from ... http://darkness.codefu.org/wordpress/2007/10/09/289 I rebuilt EPEL’s mod_fcgid package with the latest mod_fcgid (2.2 I believe) with no problems. Make sure to define a macro like rhel with value 5 to get the SELinux policy module built too (echo '%rhel 5' >> ~/.rpmmacros or maybe rpmbuild --define 'rhel 5' ...). Now, I’m using FastCGI and Apache’s suEXEC to run ... http://darkness.codefu.org/wordpress/2007/09/26/288 We just got another server at The Planet. They had a deal on another of the same 1600SC’s we got before: dual Xeon, but this time with dual 10k 136GB SCSI disks. They offer CentOS 5 now. (When we bought our last one, they only offered RHEL 3, which I had to ... http://darkness.codefu.org/wordpress/2007/09/24/287 Making simple tree data structures out of things like lists and dicts in Python always pains me. In my head other languages, like maybe ECMAScript or Lua, have better syntax for this. Here’s an example of what I might write to set up a particular data structure: day = {} day["date"] = "date ... http://darkness.codefu.org/wordpress/2007/09/14/286 What I like about the XV-6700 from Verizon Wireless: I can get on the web pretty fast from anywhere; especially fast with built-in 802.11b. EV-DO (rev. 0) isn’t anything to sneeze at, either. Slide out QWERTY keyboard. Pretty decent screen, including a flip to landscape when you slide out the keyboard. Windows Live Search (and maybe Google Maps Mobile). Microsoft Voice Command. USB ... http://darkness.codefu.org/wordpress/2007/08/13/284
