This morning, I updated the blog to use permalinks (the long URLs that should permanently link to a post) to change the format from http://www.tedroche.com/blog/?p=1234 to a newer format that includes the date and a bit of the post title, like: http://www.tedroche.com/blog/2007/11/22/recommendations-for-foss-podcatcher/. This lets you see both the date of the post and title in the link, and it also is more digestable by the search engines. Rather than seeing one page named blog/ with a parameter of P that changes all the time, the search engines now see that there are twenty-eight hundred pages in that directory, each with its own name. We’ll see if it makes any difference…

Joi Ito has a lot of history in developing and supporting and running commercial businesses leading during the internet boom and, like many of us, suspected that “it was all ICANN’s fault,” and that they should get out of the way. Unlike most of us, Joi had the opportunity to do something about it, as a member of ICANN and in his post Three years with ICANN, he learns that change might not be as simple nor easy as many of us think:
With all of its tumultuous history and bumps and warts, ICANN, in my opinion, is the best way that we can manage names and numbers on the Internet and any new thing to try to do what it does would be less fair and probably wouldn’t work.
Thanks for trying, Joi, and thanks for letting us know.
Good news: OLPC extends “Give One, Get One” program to December 31. If you haven’t given yet, please consider it. If you have no use for an OLPC, they accept contributions, too.
I listen to audiocasts (I don’t have a *pod, and don’t agree with the brand implications. Since I listen on my ThinkPad, they’re PadCasts for me. Let’s say “audiocast” or we could be really retro about it and refer to them as “audio recordings” since they’re neither cast nor podded.) while working out and go through quite a few. The Conversations Network has been a great source for these: IT Conversations in particular. Phil Windley’s Technometria is one I try to catch each weekly episode. Other features, like David Heinemeier Hansson’s keynote at the 2007 RailsConf or Tim’ O’Reilly’s keynote as OSCON are other favorites. There’s lots of other good stuff on Coversations Network, so much so that I’ve contributed to the network, a non-profit 501(c)(3) organization.
But there are other, far smaller operations. I met Peter Nikolaidis through the , and he does an audiocast called “ ” with a fellow from the west coast named Harlem, a man with a voice for radio. An interesting show with contributions from many others, too, focused on Ubuntu, but ranging over many of the topics involving Open Source.
I like to keep up with all of these audiocasts (and would welcome more recommendations from others!), but it involves manually visiting the web site, checking to figure out if I’ve heard the audiocast already, and downloading it. I’m looking for an automated way of doing this.
I was (and still am!) a regular subscriber to Dave Winer’s Scripting News, and listened to his first audio enclosure (imagine that!) in his RSS feed, accessible directly through the Radio Userland built in feed reader. Since then, I’ve changed hardware a few times, operating systems at least twice, and feed reader software more times than I can recall. I’m looking for an application I can run from my Linux desktop that will regularly check the RSS feeds put out by the audicasting sites and download the new audiocasts of interests. Bonus points if the software is under a FOSS license, +1 for efficient and frugal resource use, cool interfaces, etc.
One JuiceReceiver, which doesn’t “yet” have a Linux port, despite being written in Python. It seems like there are close relatives to this code in CastPodder and IcePodder, but it’s not clear to me which of any of these projects is alive, well and legitimate. It appears to me that IcePodder has roots in the others, with directories still named iPodder (likely renamed due to near trademark infringement of a well-known player?) and a CastPodder manual buried in the download, dated 2005. (Here’s a clue: IcePodder’s About page says “IcePodder is a podcatcher (RSS client) for Linux conceived as a replacement for CastPodder. ” So my guess is that iPodder begat JuiceReceiver begat CastPodder begat IcePodder. Whether or not I’m on the “right” branch is something that a little more research ought to bring to light. (Update: a little Googling confirms the theory, and it appears to be pretty amicable.)is labeled iPodder, but points to
IcePodder was an easy install: download, unpackage, review the README and INSTALL, review and run the install.sh script. Written in Python, using wxWidgets for UI, GPL. A little shaky in operation – I’ve crashed it once or twice, but I’m running the old “stable” release rather than the current code, so I should upgrade before passing judgement. The code needs some serious search-and-replace s/CastPodder/IcePodder/g but it looks pretty promising. Anyone else have recommendations?
UPDATE:also looks promising. Don’t let the version 0.10 fool you – apparantly, that’s the version after 0.9, according to the developers…
I’ve got a WordPress blog with a couple thousand posts, upgraded several times, from a TWiki blog to a Radio Userland blog to WordPress and a couple of upgrades. And I’d like to add the new taggin features available in WordPress 2.3. Here’s what I’ve figured out from poking around: what used to be wp_category is now wp_terms and terms contains both categories and tags. The categories are hierarchical from a self-join using the group column to link back into the term’s term_id primary key. wp_terms in turn links into wp_term_taxonomy: that’s got a column named taxonomy that contains groups like ‘category’ and ‘link_tag’ and a parent column that self links into term_id, which I think is a duplication of what wp_terms is doing. There’s also a count field, meaning that we’re denormalizing the count of categories and tags, meaning if we hack at them, we’ll need to manually update this (see below). Finally, the posts are related to categories and tags using the table wp_term_relationships that’s a many-to-many link from the post’s primary key, object_id, to the term_taxonomy_id primary key of the wp_term_taxonomy table.
So, here’s the recipe to retrofit tags into some posts. I used phpMyAdmin as the web interface into the MySQL table that holds WordPress’ data. You can do the same via the mysql terminal interface or using other remote connectivity like ODBC or your choice of tools.
1. Create or update a tag in the wp_terms table. Note the term_id PK.
2. Insert the term_id and category of ‘post_tag’ into the wp_term_taxonomy table.
3. Create the linking records in wp_term_relationships with the following SQL. In this case, I’m tagging with “Ruby” any post that has “Ruby” in the title or post.
INSERT INTO wp_term_relationships
SELECT wpp.id object_id, `term_taxonomy_id`
FROM wp_posts wpp, `wp_term_taxonomy` wptt
JOIN wp_terms wpt ON wptt.term_id=wpt.term_id
AND (wpp.post_content LIKE '%Ruby%'
OR wpp.post_title LIKE '%Ruby%' )
ON DUPLICATE KEY UPDATE
(The ON DUPLICATE code is just a quick hack to tell MySQL to ignore it if you’ve already tagged some posts Ruby by hand.)
4. Hack away. When you’re all done, you’ll want to fix the count in the table with the code below:
UPDATE wp_term_taxonomy wptt
FROM wp_term_relationships wptr
WHERE wptr.term_taxonomy_id = wptt.term_taxonomy_id
GROUP BY term_taxonomy_id)
The Fedora Unity Project announces: “The Fedora Unity Project is proud to announce the release of new spin, the Everything Spin. Included in this spin are all the packages available at the time Fedora 8 was released.”
A neat feature of recent ( 7 & 8 ) Fedora releases is the ability to create your own derivative distributions based on the tools supplied with the package. This allows the LiveCD and LiveUSB features I mentioned earlier, and allows independent groups to create specialized disk images (“spins” in their inside chatter) to meet specific needs, in this case, a set of CDs for those who don’t have a DVD handy. I ran into this situation recently with a customer who had chosen to economize on his server specifications by cutting out a DVD that was likely to be used only a few times over the lifetime of the hardware. It’s cool that the Fedora build process has been made public and the tools to do this added to the distro itself.
Dan Kennedy writes in Comment is free: Space cadets, “Is seeing a UFO any more crazy than believing God created the universe in six days? It is if you are running to be president of the United States.” Go, Dan!
I have seen things in the skies I could not identify. I’ve seen meteors and comets and planets and even satellites I could identify, but I’m not an expert in astronomics nor aeronautics, so I have seen objects that may have been flying that I could not identify. I haven’t seen Elvis, and I haven’t communicated with little green men. That’s crazy talk. Which is crazier: Charles Darwin or X-Files? I’ve got that all sorted out, thanks.
Max Spevack, the benevolent dictator in charge of herding cats for the Fedora project, doesn’t announce the official release of Fedora 8 today in his posting, http://fedoraproject.org/get-fedora and hop aboard. I run Fedora, and so can you!in Red Hat Magazine, but it’s out there. (His post is actually a great HOWTO on running Fedora off a USB memory stick, neat trick that that is!)

Finally, S5 has a competitor! This one looks promising.
Max Spevack blogs fedora core 6 end of life is december 7:
Those of you who dont read the fedora-devel-announce list but who do read Fedora Planet will probably be interested in this reminder: Fedora 8 will be released on Thursday November 8th, 2007. According to our policy of “supporting release X until one month after release X 2”, Fedora Core 6s end of life date will be Friday December 7th, 2007. Fedora Core 6 Zod was released on October 24th, 2006. Its total supported lifespan will end up being 13.5 months. Fedora 7 will be supported until about 1 month after Fedora 9 is released.
This is the Paradox of Change: we want our software to evolve, keep moving forward, improving, but we hate the costs of upkeep. Backup, reinstall, reconfigure, restore, tweak, update, etc. is a long process, though worthwhile. Bear in mind that this is fedora’s legacy: it’s for folks who like to surf the cutting edge, at the cost of flatten-and-restore. If you want more stable choices, there are many, at the cost of not getting to play with (and risk getting cut on the sharp edges of) the latest stuff.
Someone at last Thursday’s LUG meeting asked about the feasibility of upgrading an Ubuntu install done “middle of last year” with the latest 7.10 release, and the folks were skeptical, at best. I recently tried an in-place upgrade of 7.04 to 7.10, but that was a pretty clean and fresh install and it went well. Others have not been so fortunate. The best practices of Freemanizing™ a machine (backup, format, install from scratch, clean installs of new versions, copy over data, preferences, scripts and settings) still has some merit, I think.
