Maria Speaks Episode 20: MPEG-4 Lessons, Server Woes, and eBay Shopping.

Transcript:

Hi, I’m Maria Langer. Welcome to Maria Speaks Episode 20: MPEG-4 Lessons, Server Woes, and eBay Shopping. This episode is a hodgepodge of information related to my podcasting efforts and the trouble it has been giving me lately. You can find the transcript of this podcast in the “Call Me a Geek” area of Maria’s WebLog. The easiest way to find that is to click the link on my home page, www.aneclecticmind.com.

Let’s start with the MPEG-4 lessons. If you’ve been following my podcasts, you know that I’ve begun creating the occasional enhanced podcast. Enhanced podcasts include images and links and are saved in MPEG-4 format with a .m4a extension. My other podcasts are saved in MP3 format with a .mp3 extension.

Podcast publishing is not exactly a simple task — well, not when you do it the way I do. After recording, editing, and saving the audio file, I then log into Blogger where I create a blog entry for the podcast. There’s a link field that I fill out with the URL for the audio file’s location on a server. I put a short blurb about the episode in the entry and publish it.

Publishing the entry on Blogger does two things. First, it creates the Maria Speaks home page. That’s the plain old Web page you see when you browse www.aneclecticmind.com/mariaspeaks. Then it creates an XML feed file called atom.xml, in the same location as the home page. This feed file has all the codes necessary for podcatching software — like iTunes and a bunch of others I really don’t know — to see and download the new audio files.

But that’s not what most subscribers use to access my podcast. They use my Feedburner feed. Every 30 minutes or so, Feedburner’s software checks out my atom.xml file to see if it has changed. If it has, it revises its version of my xml feed file, which can be found at feeds.feedburner.com/mariaspeaks. That’s the file most subscribers subscribe to and it’s the one with all the bells and whistles to make sure my podcast entries appear correctly in the iTunes Music Store and elsewhere.

Sound confusing? It is, in a way. But I don’t usually have to deal with too much of it. As I said, I create and save the audio file, then create and publish the corresponding blog entry. Blogger, Feedburner, and subscriber’s software does the rest.

My MPEG-4 lesson started yesterday. Well, in all honestly, it started about four months ago, but I didn’t realize it then. Back then, it was a problem getting my podcasts to work. But I changed the way I was doing things and it started to work, so I assumed I’d been doing it wrong in the first place. Actually, I wasn’t.

Here’s the symptom: my enhanced podcasts weren’t accessible from the Maria Speaks podcast. Anyone trying to access the file from the Maria Speaks home page by clicking the entry name got an error message. File not found. And there was no attachment to either version of the xml feed file.

The regular podcasts were fine.

Thus began my troubleshooting exercise. I zeroed in on the difference in the file name extensions and started researching. To make a long story short, I discovered that in order for me to include m4a files in my podcasts, I had to set up a MIME mapping on the server to identify the m4a extension’s type as audio/MPEG.

If you’re completely lost, don’t worry about it. This isn’t the kind of thing most computer users need to deal with. I certainly don’t. Fortunately, I have a server in my office that I can set up MIME mapping. I added the appropriate entry, moved my m4a files over to that server, fixed the URLs in Blogger, republished, resynced Feedburner, and everything began working fine.

I’m still trying to find out if the server space I have on GoDaddy.com can be modified to add the MIME mapping I need there. I’d much rather serve from that server than the one in my office.

So that was my MPEG-4 lesson.

Server woes started this morning. I was still fiddling around with the MPEG-4 files and was very surprised to see that the folder on my GoDaddy server that I’d been using to store my MP3 files was gone. I mean gone like it was never there. And oddly enough, two folders that I thought I’d deleted were back. What the heck was going on?

I assumed that I’d accidentally deleted the missing folder and was mistaken about the other two folders. After all, I’ve been busy lately with my QuickBooks book and a bunch of unexpected helicopter charters. I was obviously being careless. So I rebuilt the missing folder from backup files on my iDisk and went to work.

All the way to work — it’s a ten-minute drive — I thought about my carelessness. And when I got to my office, I did some more research. What I soon realized was that all of the space on my GoDaddy server had been reverted to the way it looked on October 10. Over a month ago. What the heck was going on?

I called GoDaddy technical support and was fortunate enough to have a tech guy answer right away. I told him the symptoms. We did some brainstorming, using the info we both had. We soon discovered that on October 10, I’d requested a change from a Windows server to a Linux server. For some reason, it had taken GoDaddy five weeks to process the change. In the meantime, I kept uploading files to the Windows server when the Linux server was already set up but not accessible to my account. Last night, GoDaddy switched my access to the Linux server, which hadn’t been updated since I requested the change. So I was suddenly faced with a server that hadn’t been updated for five weeks and access to the server I’d been using all along was completely cut off.

Well, this wouldn’t have been so bad if I was using the server space for a Web site. I keep backup copies of all my Web site on my main production computer. If a Web site’s directory or disk is trashed, I can have it replaced in a matter of minutes. But the only thing I use this server for is storing my podcasting files. Not just for Maria Speaks but for KBSZ-AM’s Around the Town radio show, which is broadcast every weekday. When GoDaddy made its change, it wiped out about 20 podcast files.

The really tragic part of all this is that I’d been saving all those podcast audio files on my PowerBook’s hard disk. Two days ago, I got an onscreen message saying I was running out of disk space. Well, why not delete some of those podcasts, I asked myself. After all, I can always get new copies from the server.

Two days later, of course, I couldn’t.

Well, the GoDaddy tech guy was very helpful. He told me they’d do a server restore for the Windows server and copy the files in my directory there to the Linux server. Although GoDaddy usually charges $150 for this service, they admitted that they were at least partially at fault for the screw-up and waived the fee. Now I just have to wait up to 10 days for the files to reappear. And, when that happens, I have to re-upload any files I uploaded to the server between yesterday at midnight and the day the server is restored. Like this podcast.

Oh, and I did lose one of my enhanced podcast episodes. It was one of my better ones, too: Mac and Windows File Sharing. It was on my .

Mac disk space, which I also cleaned up in an effort to get rid of unneeded files. So if you have a copy of it — that’s the version with the m4a file extension — please send it to me at mariaspeaks@mac.com. I’d really like to put it back online for the latecomers here. The lesson I learned in this ordeal is that I must have a copy of every single file I want to make available on a server. If I’d had all my files, I could have just restored the server back to its original condition and got on with my life. And not bore you with this story.

SmartDiskWhat’s weird about this is that I considered the server my backup and I deleted the originals, depending on the backup. If you recall my famous NaNoWriMo podcast episode, you’ll remember how I spoke about the importance of backups. Yeah, well the originals are important, too. Which brings me to the final topic of this podcast: eBay shopping. I’ve been surfing eBay for the past two weeks, trying to get a deal on a portable FireWire hard disk. The idea is to use the external hard disk to store all my media files, thus keeping them off my PowerBook’s internal hard disk, which is only 40GB. SmartDisk makes a drive called the FireLite and I figure I can get an 80GB model for about $130. There’s plenty to choose from, all in unopened boxes. But I seem to have the worst timing; I’ve lost about a dozen auctions in the past two weeks. I’ve gotten to the point where I actually bid on two of them at a time, knowing I can’t possibly win both.

That’s the same technique I used to snag a new iSight camera this week. I put the same bid on both cameras. I won one and lost the other. Fine with me. I figure I’ll bring the camera home and use it on my laptop for a Webcam and for iChat. I might also do some video podcasting — but don’t hold your breath on that.

My other big eBay acquisition is Mac OS X 10.4 Tiger Server Unlimited. It’s about half the price on eBay as it is in the Apple Store. Sealed boxes, unregistered. Sounds almost too good to be true. We’ll see.

The server, of course, is so I can finally get rid of WebSTAR and do some serious Web hosting on my server. I’ll bore you with that in another blog entry.

That’s all for today. I hope you learned something from this mess. Thanks for listening!

Shopping on eBay

I try — and fail — to get a few good bargains. But I’m not giving up.

I talked to my brother the other day. He lives back east, in the NY/NJ metro area, with his wife and dog. They live in suburbia, on a curving, tree-lined street where the houses don’t all look like each other. The first time I visited him, he had maple trees growing in his gutter. He’d just bought the house, which needed some work, and he hadn’t gotten around to cleaning the gutters yet. The trees were only a few inches tall. When we lived in New Jersey, we had a 4-foot maple growing on our roof for a while.

Anyway, my brother buys just about all of his electronic equipment on eBay. The other day, he’d just bought himself a new cell phone and was waiting for it to arrive. He already had the hands-free, bluetooth headset that would work with it and was trying it out with his wife’s phone. It seems like every time I talk to him he’s telling me about some new gadget he bought on eBay.

I’m in the market for a few electronic devices myself. So I blew the dust off my eBay account and logged in. What I discovered is that eBay is no longer the garage sale of the Internet. It’s now the flea market of the Internet.

Why the difference? Well, a garage sale is usually full of used stuff — much of it junk — that the owner no longer wants. A flea market has much of the same junk, but it also has brand new, still in the box (abbreviated NIB for “new in box” on eBay) items. Call me spoiled, but when I buy a piece of computer hardware that I need to depend on, I want it brand new.

The first thing I needed was a portable external hard disk that I could use with my PowerBook. Experimentation the other day with iMovie and my video camera ate up the remaining 5 GB of unused space on that computer’s disk. I’m not replacing the hard disk — Mike went through that with a local computer consultant a few months ago and it was a 2-month nightmare. Instead, I’ll get a portable FireWire hard disk I can use to store big, fat media files. Like video. (Although it wouldn’t hurt to pare down my iTunes library on that computer; 12 GB of music is a bit much when I carry around the same songs and video on my iPod.)

So I hunted around on reputable sites — including the Apple Web site — and found a name brand and model I liked. Then I searched on eBay. I had literally dozens of matches, many of them NIB. Wow.

At the same time, I decided I needed some more RAM for my G4, which will soon be upgraded to Mac OS X 10.4 Tiger Server. The machine, which is currently doing server duty with the dreaded WebSTAR, has 384 MB of RAM. That was quite generous when the machine was new 4 or 5 years ago, but nowadays, it just doesn’t cut it. Especially with the Webcam and audio streaming software running on it. Near as I can figure (without opening the box), one of its 3 RAM slots should be free. I figure I’d put 512 MB in there to pump up the RAM. And, if I could get the RAM cheap enough, I’d buy 2 512 MB “sticks” (apparently the RAM lingo) and throw away (or eBay) the 128 MB one I pull out. I did a search and found dozens of compatible RAM sticks. Whew.

I started bidding. And after two days, I noticed a pattern that I had noticed once before. You can be the winning bidder right up until about 10 minutes before bidding ends. Then someone comes along and outbids you. If you’re paying attention, you can bid back. That results in a bidding war and, if you’re not careful, you’ll wind up paying more than you really wanted to.

I’m careful. And I know how much these items are worth at their cheapest (or cheapest I can find) retail source. So someone outbids me and I start the process all over again with another item.

I have a theory about this. I believe that some vendors who sell the same thing over and over — dealers, in a way — have buddies who help them out near the end of an auction. Their buddies come along and bid to get the price up. They’ll bid right up to the amount the dealer really wants and step back. The bidder that crosses that line pays more than the dealer’s bottom line. And if there is no other bidder, the dealer pays the listing fee on the price his buddy “paid” and re-lists the item. This is how so many items can be sold without reserve. (A reserve is a minimum price the seller will accept. It costs more to list with a reserve and lots of buyers won’t bid on products that have reserve prices.)

The long and the short of it is that I’ll probably be ordering that RAM from an online retailer today. I can’t seem to get it on eBay any cheaper than I could get it from a retailer, so why risk a private seller on eBay?

I haven’t given up on the FireWire hard disk yet. And I’ve started looking into another iSight camera for a portable Webcam. And you know, I can really use a FireWire hub…

I really AM a geek!

I discover enhanced podcasts and just have to try making one myself.

Yesterday, after getting my dose of news from Salon and Slate, I checked out the iTunes Music Store’s Podcast Directory. I found CockpitCast, “A podcast from the $16million airplane strapped to my ass.” It’s a mildly interesting podcast for people into aviation, full of control tower chatter and radio communications as a pair of jet pilots fly from LAX to other points. I noticed that some of the episodes were marked as “enhanced” and wondered what that meant. It all became clear when I played one in iTunes.

Now please do forgive me. I know I make a living writing about computer topics, but I’m in the middle of a revision of a QuickBooks book right now and I’m trying hard to keep my mind off things like podcasting. So enhanced podcasts made their debut and I missed them. It won’t be the first time I missed a computer innovation and I’m sure it won’t be the last.

Well, the CockpitCast enhanced podcast included photos. And frankly, that kind of blew me away.

You see, I’ve been creating how-to podcasts on Maria Speaks — podcasts that teach people how to do things with their computer. One of the things the podcasts lacked was the ability to include screenshots, which can really help make an article understandable. I made up for that loss by including the transcript of each podcast on a Web site that I reference in the podcast. But with enhanced podcasts, I can now include the screenshots in the podcast itself.

I wasted no time locating and downloading a pair of software programs that would give me the ability to create these enhanced podcasts: Cast Easy and Podcast Maker. Although I first preferred Cast Easy, I soon realized that Podcast Maker was a much better product. And at only $30, it was quite affordable.

Podcast Maker enables you to take an audio file in MP3 or M4A format, insert chapters with pictures and link, and save it as a podcast. It’s very easy. (It’s also very disheartening, since I spent close to two days writing an eBook about how to create a podcast. Still my eBook explains how you can do it for free, so there’s some benefit there. Of course, that’s not an enhanced podcast. But it is a podcast with a customizable Web site. Oh, forget it.)

This afternoon, after finally finishing the 62-page Chapter 2 of my QuickBooks book revision, I came home and converted one of my Maria Speaks podcasts into an enhanced podcast. I used one that had a lot of screenshots. It explains how to send and receive faxes using Mac OS X Tiger. And it came out very nice, if I do say so myself. I just wish my voice wasn’t so nasal — I had a nasty cold when I recorded that episode.

Want to check it out? Visit http://feeds.feedburner.com/mariaspeaks/. Or better yet, just use that URL to subscribe to the podcast with iTunes 6.0 or later. You’ll see all the images in the iTunes window, or, if you have a new video iPod, you’ll see it on your iPod screen.

If anything was a motivator to get my QuickBooks book done quickly, this is it. I can’t wait to have a few spare hours to play around with this new technology. Stay tuned. I’m sure this isn’t the last enhanced podcast you’ll get from me.

7.1 Piglets!

I buy a new digital camera.

I was at the Apple Store in Tucson last week. I did a presentation on their 30-inch monitor for a small group of Mac OS X users. It was probably the best presentation I did because the audience was involved, which kept me animated, and they shared some of their tips with me, so I learned something, too.

Like many Apple stores, Tucson’s 30-inch monitor is set up close to the digital cameras. So close, in fact, that I fiddled around with the cameras on display while talking to a shopper before I began. I began admiring a Canon model that would take 5.0 megapixel images (or 5.0 piglet images, as my stepfather would say) and still fit in my purse. That sure beat the 2.1 piglet model I was carrying around. Except I wasn’t carrying it around. I’d left it home. Tucson was our first stop on a trip to Maine. We would leave the following morning, straight from our Tucson hotel to Phoenix Sky Harbor Airport and beyond. When I was packing, I couldn’t find the battery charger for the 2.1 piglet Canon, so I’d left it home. No sense bringing a camera if you can’t charge the battery. I have another Canon camera, a 5.0 piglet G5, which I’d bought for aerial photography work. It wouldn’t fit in my purse, but it took great pictures.

Now here I was at the Apple Store, looking at a camera that would do the same thing and still fit in my purse.

Did I mention I got a royalty check last week? It arrived the day before we went to Tucson. It was a very nice check. The kind of check that makes you want to buy a round of drinks in the local bar. Or buy yourself a new toy.

It didn’t take much convincing. Mike, to his credit, tried to remain neutral throughout. But somehow I convinced myself to buy it. And it was kind of nice that the Apple Store offers discounts to Pearson authors. It wasn’t a big discount, but a small discount is better than no discount.

The sales guy at the counter went into the back and returned with two boxes that looked identical.”I only want one,” I said cheerfully.”Yes,” he said, “but I thought you might like to see this model. It’s basically the same camera, but it has 7.1 megapixels. That means you can make bigger enlargements.”He began a discussion of why more piglets is better than less. I already knew so I gently cut him short. Mike and I discussed it. The price difference wasn’t major. And that royalty check had been quite impressive. I talked myself into the upgrade.

So now I have a 7.1 piglet camera in my purse.

I took some photos in Maine. My favorite is above.

And I didn’t even take the G5 out of its camera bag.

Maria Speaks Goes Online

I finally start publishing my own podcast.

Maria SpeaksI’ve been wanting to do it for weeks, but I just haven’t found the time. You see, I don’t want to sound like an idiot, so I need to compose everything I want to say in a podcast episode before I record it. So I need time to think things out, write them down, and record them. I suspect I’m not the only one who does this, although I’m willing to bet that a lot of podcasters skip the first two steps.

I published two back-dated podcasts this evening. One is an introduction to the podcast. The other provides information about my eBook on podcasting. I’m working on another one now, about using the Mac OS Command key. Maybe I’ll get that online this week, too.

Interested in podcasting stats? I found this information in the most recent issue of Technology Review.

  • By the end of June, there were over 25,000 podcast feeds. That’s up from less than 2,000 in January. Wowser!
  • The iTunes Music Store’s Podcast Directory listed about 6,000 podcast feeds with about 6 million subscribers as of July 18.
  • Most podcasts categories have more listings than views (percentage-wise, anyway). The notable exceptions include radio (such as KBSZ), News, Health/Fitness, Books, Hobbies, Games, Food/Drink, Travel, Art, Erotica, Environment, Variety, and Fashion.

Jeez, I love stats.

Want some more stats? Here’s a quickie: the KBSZ podcast I set up in August now has 20 regular subscribers. That’s not bad for a radio station on the edge on nowhere.

Anyway, if you want to subscribe to my Podcast, here’s the URL: http://feeds.feedburner.com/mariaspeaks — just pop that URL into iTunes or another Podcast client to tune in. Or use your Web browser to access the RSS feed and click the title of an episode to download it.
