At last: car stereos with frontal mini-jacks

JVC car stereo with line-in
You need portable MP3 player for when you’re on the move. On the move includes: in the car. Why would you want to listen through tiny white earphones, if you have dozens of Watt of pure musical power already at your disposal in that car of yours? Or: how to connect your iPod to your car stereo.

FM Transmitter

First of all, they’re illegal in Belgium, so you can’t buy them anywhere here. Thanks to my numerous maffia friends however, I’ve been able to try 2 Griffins and a white-label gizmo, but my experiences have always been disappointing: impossible to tune right or get an acceptable sound.

Fake tape

There are these cassette look-alikes that you can put in your tape player. Only, who still has a tape player in his car? And what does the conversion electric-to-magnetic-to-electric do for your sound quality?

Custom interfaces

Alpine has a special solution for iPod (didn’t BMW have something like that too?), but we don’t like vendor lock-in.

Line/Aux in

  • One year ago I had already talked about Kenwood making car radios with line-in possibility. But Kenwood used the RCA jack on the back of the device, which might have been a good idea in a hifi-stereo world, but not so for portable audio players.I wanted a mini-jack, damn it, but no vendor had that.
  • But now: behold the mini-jack!
    - Sony has the CDX-GT200 (about € 130) and its bigger brothers CDX-GT300 and CDX-GT400 (not in Europe).
    - JVC has the KD-G612 (bout € 150) with “Front AUX Input”, as well as the KD-G510 or KD-ADV6160 (last one even plays DVDs)

I hope the rest of the vendors get the message and provide a frontal AUX in on their products. Car stereos, boomboxes, mini-chains, DVD players, DivX players, …
Rip, Mix, Plug it in!

You might know I like visualizing stuff, so I worked a bit on my Get-Remix-Deliver flowchart to make it into a scratchpad to play with.

Thought DMCA was bad? Here’s DTCS!

While people were buying Christmas trees and turkeys, the U.S. House of Representatives, and specifically Jim Sensenbrenner (Republican) and John Conyers (Democrat), have prepared a very nice gift to the MPAA:

(…) I’d like to continue by looking at H.R. 4569, the Digital Transition Content Security Act of 2005, which proves the point I’ve made many times over the years, that when it comes to technology, government doesn’t really know what it is doing. H.R. 4569, which was introduced in the U.S. House of Representatives on December 16th, is intended to protect the intellectual property rights of movie studios by MAKING ANALOG-TO-DIGITAL CONVERSION ILLEGAL.

Under the Act as proposed, manufacturers will have one year after passage to stop making devices that convert analog signals like music and video into digital forms unless those forms preserve some original Digital Rights Management technology present in presumably the pre-analog stage.

What this is about, then, isn’t making it illegal to use a digital recorder to record from analog microphone. Heck, that would destroy the music industry. Congress’s thinking (if we dare call it that — I see no flashes of synapses firing) is that media are going digital more and more and the greatest opportunity for snatching content is during the actual performance when, for the sake of driving a screen or a speaker, the digital signal goes analog.

What’s covered by this proposed law are things like TiVO and RePlay Digital Video Recorders, TV tuner cards for your PC, software intended to record audio or video streams, or just about any device or program you might use to actually implement that part of the Digital Millennium Copyright Act that says you have the right (though soon not the equipment) to backup or media-shift your own music and movies.
(from I, Cringely)

And someone had the same reflection as I had and did the research for me:

When I go to opensecrets.org and look who Jim Sensenbrenner’s top contributors are a few names tend to stand out: Broadcast Music Inc. (BMI), News Corp., Comcast Corp., Viacom Inc., Motion Picture Assn of America (MPAA) and the Major League Baseball Commissioner’s Office. It’s also interesting to note on Sensenbrenner’s latest reported personal financial statement that he received two all expense paid trips (including other family members) to Vegas and New Orleans from the National Association of Broadcasters and the National Cable and Telecomm Association. I wonder if he was flying first class and I wonder if these people want you to have your TiVo or not?

And isn’t it ironic when you look up John Conyers’ financial information that you find some of the same and some new names as well. Some of the names that stick out as John Conyers’ largest financial contributors? Comcast Corp., Clear Channel Communications, Major League Baseball Commissioner’s Office and ASCAP.

Christmas present: podcast feed validator!

I get a lot of “what is wrong with my podcast feed?” kind of questions because I have written a fairly popular tutorial on podcasting with Blogger and Feedburner, and a lot of people start doing podcasts that way. There’s a couple of things that can go wrong:

  • Not a valid RSS feed
  • RSS feed without enclosures
  • Feed not updated when posting new article

To check some of those things, I needed to read and interpret the RSS feed by hand. That’s why I decided to make a podcast feed validator to do the checks automatically. Let’s take Adam Curry‘s DailySourcecode podcast as an example:

  • the URL of the feed is radio.weblogs.com/ 0001014/ categories/ dailySourceCode/ rss.xml, so I input it into the input field and the results are:
  • #1: feed URL exists and can be reached
  • #2: feed is a valid RSS feed (but does not conatin the iTunes extensions),
  • #3: feed items have audio enclosure (but not all, as you see in the image below. The reason is that two enclosures are wrongly specified as text/html instead of audio/mpeg.)
  • #4: the audio enclosure (MP3 file) exists and can be reached

podcast feed validator
So the enhancements for this feed would be: make sure all enclosures have the right type, and provide iTunes meta data. Better still: use Feedburner to get that and more: subscriber statistics and lots of feed tools.

Try it out for yourself:
Check your podcast RSS feed!

Some more features of the podcast feed check:

  • estimation of mean-time-between-posts (MTBP), a metric I talked about in RFM for RSS feeds
  • estimation of required bandwidth/storage per month (DailySourcecode: 600MB/month, 175-25.be podcast: 10MB/month)
  • works with MP3 audio enclosures and AAC (MPEG-4) audio/video enclosures (any audio/mp* enclosure)
  • detailed (technical) information is hidden by default and can be shown through some AJAX functionality.
