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!

Technorati: mp3 – car – caraudio – ipod

You might have heard that the Microsoft IE team (and Outlook 12 team) is adopting the orange square ‘feed’ logo for its web feeds:

I’m excited to announce that we’re adopting the icon used in Firefox. John and Chris were very enthusiastic about allowing us (and anyone in the community) to use their icon. This isn’t the first time that we’ve worked with the Mozilla team to exchange ideas and encourage consistency between browsers, and we’re sure it won’t be the last.
(from blogs.msdn.com)

So I decided to update my previous podcast logos with the new graphic:
(If you want to use them, and need the HTML code to copy/paste, check my podcast icon wizard)

Simple icons

: Podcast RSS (generic)

Audio podcasts

: Audio RSS
: Audio RSS (Apple iTunes AAC)
: Audio RSS (MP3)
: Audio RSS (QuickTime MP4)
: Audio RSS (Ogg Vorbis)
: Audio RSS (RealAudio RAM)
: Audio RSS (Windows Media WMA)

Video podcasts

: Video RSS
: Video RSS (Windows AVI)
: Video RSS (DivX)
: Video RSS (Quicktime MOV)
: Video RSS (Quicktime MP4)
: Video RSS (Quicktime)
: Video RSS (Windows WMV)
: Video RSS (XVid)

If you want to know whyI don’t use the acronyms “RSS” or “XML” in the icons, check Web feeds are like RSS, only different.

Technorati: podcast – icon – feed – logo – rss

Bad wake-up call: theregister.co.uk reports on Erik Marcus, a podcaster who has had his podcast feed hijacked by Podkeyword.com (no link, you know why). Why am I concerned? Guess under what name my Smoothpod Mashup podcast is registered in iTunes?

What is podcast hijacking

(…) it merely involves finding a target podcast, and creating a new unique URL for it on a website you control. You then point your URL to the RSS feed of the target podcast. Next, you do what it takes to make sure that as new podcast search engines come to market, the page each engine creates for your target podcast points to your URL instead of the podcast creator’s official URL. (Colette Vogele)
So years can go by and then the hijacker strikes: At some point, [the hijacker] can then spring out of the woodwork and demand payment from [the] target [podcaster].” The podcaster is “supremely vulnerable”, because the hijacker can at any moment change URL pointer to any other show of the hijacker’s desire and the target podcaster’s audience will “vanish.” (corante)

So someone provides a mirror service for your podcast feed, gets it registered with major podcast directories and search engines and can then choose whether to just mirror your feed, alter it (e.g. insert advertising), or replace it by whatever he feels like. That, in short, is the businessplan of podkeyword.

Who is behind podkeyword?

Some research shows that a George Lambert from Nashua (NH) is the owner of podkeyword.com (registered in Oct 2004). He also has Goldenware Travel Technologies (goldenware.com), providing airline timetable services (so he’s used to repackaging other people’s data). Another of his projects is cashcowmarketingplan.com, a spam-infested blog on “getting rich quick on the Internet”. This is worrying!

Let’s get rid of podkeyword

Here is what has to be done:

by every podcaster

check if you are affected: search for your podcast to see if it has been hijacked:
on iTunes: subscribe to your own feed because you won’t be able to see the actual feed URL unless you’re subcribed. If it’s a podkeyword URL, click the “Report a concern” button and tell Apple this is a wrong feed URL, give them the right one.
on Yahoo: search for it and if both your real feed and the podkeyword feed are present (I found 2 podkeyword feeds for my own podcast), give the hijacked ones a bad review (give it 1 star and write a review about the hijack)

by every podcast directory/search engine (iTunes, Yahoo, you listening?)

restore hijacked feeds (Remark: the following is NOT real code, just some pseudo code to clearly explain what should be done)

for $victimFeedURL in (*.podkeyword.com feeds){
# get the content of the feed
$victimFeedXML=getHTTP($victimFeedURL);
#every feed contains the URL of the homepage
$victimSiteURL=ParseRSS($victimFeedXML,"channel.link");
#get the HTML of the homepage
$victimSiteHTML=getHTTP($victimsiteURL);
# get the URL of the feed the author has specified
$victimRealFeed=parseHTML($victimSiteHTML,
"head.link('application/rss+xml')");
if($victimRealFeed  "" AND $victimRealFeed  $victimFeedURL){
#replace *.podkeyword.com by real feed URL
$victimFeedURL=$victimRealFeed;
}
}

by Feedburner (since they are an important podcast feed provider)

detect the feeds that are being queried by podkeyword (I don’t see them showing up as a separate UserAgent in my Feedburner stats, but Eric Lunt and his gang won’t have too much trouble finding them anyway) and (a) warn the feed owners that they might be hijacked, (b) offer the feed owners the option to include an extra post in their feed to alert their subscribers to switch to the real feed.

Doesn’t Feedburner do the same kind of thing?

Not at all. Feedburner also mirrors and alters RSS feeds but there are some really big differences:

1. Feedburner is not evil. That is my opinion and I might be wrong, but I’ve had contact with Feedburner on several occasions and they seem to be a bunch of intelligent and down-to-earth geeks. Plus they have found a way to make money with Feedburner without taking advantage of people.
2. Feedburner has added value: they convert a feed to a valid podcast feed, they can splice different feeds together, they provide essential stats.They deserve their place as a middleman.
3. Most importantly: I have voluntarily chosen Feedburner as my service provider! I configured it myself and I added the Feedburner RSS feed link to my blog’s HTML template. On the other hand, I didn’t contact podkeyword, I have never asked them to do anything for me.
