Our main iTunes box had flaky RAM -a heck of a problem to debug by itself- so it used to BSOD quite a lot during the past couple of months. One of the most common side effects was that the iTunes Podcast playlist would appear empty every now and then. Luckily this is addressed in the Apple Knowledge Base and the solution amounts to using File|Add Folder to Library to add the {iTunes Music folder}/podcast folder to the library. Then you will have to re-activate your subscriptions by pressing the “Subscribe” button for all your favorite podcasts.

A few weeks ago I upgraded my wife’s iPod Touch to 2.1, and I just can’t believe that iTunes won’t let you backup your content even if it means a paid firmware upgrade. I would have used PodsBlitz to back it up, except that Apple decided that it would be a good idea to strip off the disk mode from the iPod Touch.
I decided that there was nothing to be done for the music files: I would have copy the files manually after the upgrade, hoping to replicate my wife’s original selection as closely as possible. But that iPod also has a few of my daugther’s favorite movies… I rightly believed we could have a problem there. I’ve been converting her favorite DVDs for a year, and I carelessly deleted the converted files from the PC a long time ago leaving two options: either invest a few afternoons re-converting those DVDs, or somehow get those files out of the iPod and restore them later.
After a few google searches I stumbled upon a couple of promising projects that some day may grant you unrestricted access to the media residing in your iPod Touch, but those just refused to work in my wife’s PC. A few more queries later I found DigiDNA DiskAid, a nice little utility that speaks the iPod’s obscure file transfer protocol over USB and that lets you copy files back and forth. It’s far from perfect — it wiill only show the physical filename instead of the “real”, tag-based one, and it only does alphabetical sorting, even when sorting by file size. This made hunting for those movie files kind of annoying — annoying but *possible*, which is a lot more that can be said for Apple’s tools.

For completeness, here’s a followup to my post about using a Nokia N95 as a bluetooth modem under Linux. This is a working wvdial configuration for use with Telcel in Mexico.
Remember to enter your SIM’s PIN in pin-telcel, and refer to my previous post for complete instructions.

To use it, enter

Enjoy!

Did you know that you can use your data-enabled N95 to get a thethered Internet connection from Linux? The access mode and speed will depend on your actual coberture, and as usual YMMV, but I’ve been using this setup for a few months and it works fine.

Now in user mode use KBlueMon to find out the Bluetooth address of your device and write it down.
Then go ahead and initiate an OBEX file transfer to make sure that you can actually link to your phone and to establish a trust relationship. In your phone add the Laptop to your trusted device list, so it won’t nag you whenever you establish a link.
Now edit /etc/bluetooth/rfcomm.conf :

Replace your own device address after “device”.
Now edit /etc/wvdial to add these two entries:

You can give them any name you want. I have defined several providers, to avoid confusions and to use the provider at hand. Replace the “XXXX” in Init1 with your SIM’s PIN.
Now to use them restart the Bluetooth subsystem:

And use wvdial to dial out:

You should get an Internet link, complete with an IP, a default route and a couple of DNS servers. If it doesn’t, reboot your phone liberally.
Please note that this might get expensive quite quickly unless you get a data plan from your provider. Go ahead and make their day.
Enjoy!

Rafael Garcia-Suarez shares a helpful tip to correctly enable APM in his D420 running Ubuntu, but I can confirm that my D620 behaves the same -ignoring APM level 255 and disabling APM completely instead- and that his fix runs equally well, just by adding

to /etc/hdparm.conf and making sure that /etc/init.d/hdparm runs at startup (the default after apt-get installing hdparm in my case).

Hisaaki Shibata took Michael Rolig’s shark.c -which I use to control my radioSHARK from Linux- made it work with the new radioSHARK 2 and released the new shark2.c (local mirror).
With this development owners of the new radioSHARK 2 can control their shiny new device under Linux to change stations and change its lighting besides other neat tricks like live Internet streaming with icecast2 and darkice as I’ve written before.
I haven’t been able to lay my hands on a radioSHARK 2 but I might do it soon. I hope that griffin has finally managed to solve the annoying bugs in the software that made the original radioSHARK completely unusable under Windows, but keep in mind that Michael and Hisaaki’s work has made the enclosed software completely irrelevant to Linux users, opening a new market for a fine hardware product.

Last week Jordi Fernández gave me a quick hands-on tutorial for a working Beryl setup on Debian. He owns a Dell Latitude D620 running Debian GNU/Linux just like mine, so leeching his setup was even easier for me. What sold me immediately into Beryl is that you don’t need to install Xgl.
Basically I edited /etc/X11/xorg.conf and added these lines to the Device section:

and added a new section to the very end:

My updated xorg.conf is available right here.
After restarting X (ctrl-alt-Backspace for lazy users like me) you can type this on a terminal:

I have the official nvidia drivers (1.0-8776) installed via module-assistant and a Beryl version that is kind of old (0.2.0+svn20070205-r3687+imudebian0, rather ancient in Internet Time). This worked immediately for me but Your Mileage May Vary.
There you have it. A working beryl setup in a few minutes. Thanks to Jordi for this tutorial and the rather impressive demo that followed, and to the Compiz and Beryl developers for their hard work.

When my iPod died I complained -ranted, actually- about the lack of a decent backup program for it. Well, I finally found a program that does just what I need. PodsBlitz will display the songs in your iPod, and moreover, it will merrily dump them to your hard disk. For backup purposes, I repeat. This will backup all MP3 files with their corresponding tag information, but you’ll still have to backup ratings and all other metainformation the old, manual, XML-based way.
PodsBlitz is written in Java and is distributed as a single .jar file that will execute under Windows, MacOS X and most Linux desktops with a fairly recent Java Runtime Environment. The best part is that it doesn’t need to install drivers or do any kind of fancy USB magic to find your iPod. You just dump it into the root directory of your iPod and it just works! Kudos to Alexander Dietrich for this nice software utility!

After a few weeks using the auxiliary battery instead of the CD-ROM drive, I needed to read a DVD. Surprise! It didn’t work. Reboot. Still no luck.
dmesg didn’t show anything about IDE, and /proc/ide was empty. It was like the CD-ROM didn’t exists at all.
The explanation might be that the CD-ROM is a SATA drive, not PATA. Graham William’s GNU/Linux Desktop Survival Guide holds the key to enable the drive. In short:

Voilá.
(Part of the ongoing Debian GNU/Linux on Dell D620 saga.

I managed to get TwinView working on the Dell Latitude D620 under Debian GNU/Linux and I’ve been using it for a few weeks now without any problem whatsoever.

The key section in /etc/X11/xorg.conf is this:

I’m using an external 1280×1024 LCD, and I use the KDE control center (Peripherals/Display) to switch between metamodes. The nice thing is that whenever the X server starts and it doesn’t sense the external display it automagically defaults to using only the built-in display. Moreover, TwinView handles gracefully the “hole” below the 1440×900 display. Now what I’d really like to do is to specify that the primary monitor is the built-in display instead of the external LCD, but that can wait a bit longer.

Of course, you can download the complete xorg.conf I’m using, with my finely-tuned (right) TrackPoint and TouchPad configuration.

Of course, this assumes that you are using Debian GNU/Linux with kernel 2.6.x and hotplug, and has been documented on my Debian GNU/Linux on Dell D620 page.

As i wrote before, given my (mis)adventures with IBM/Lenovo I decided to change my allegiances and switch to another brand. So during the research phase I took some time to go to the Dell Expo and get to know their laptops firsthand.
One of the questions I had was about the keyboard: after so many years of working with Thinkpads I have become addicted to the TrackPoint, and I was sure that I had seen photos of Dell laptops with such device, so whatever laptop I decided for really had to have it.
I quickly found out that the laptops in the business line -the Latitudes- are the only models to sport such contraption under the Dell-esque name of “Track Stick”. As a matter of fact, besides the Thinkpads they are the only notebooks *anywhere* that still have it, so either they were found unusable by a significant amount of people or IBM tried to milk its patents just a bit too much. Personally, I believe the Trackpoint is the invention of the century right next to the Twiddler (and lately, even _on_ the Twiddler2) but then again some people believe I am somewhat eccentric when it comes to input devices.
So there I was with the entire Latitude line before me to consider. The D420 is very nice and would make a killer travel notebook, but its specs are somewhat conservative for my needs. And the D820 has a nice screen but is way too heavy. So I settled for the D620. I received it last week and I am documenting how to make it work with Debian GNU/Linux.
So here is my hands-on review of the Dell Latitude D620:
Pros:

• Lightweight: About 4kg with the extra battery.
• Has a TrackPoint (great for mouse navigation) and a Touchpad (great for erratical mouse movement while typing but useful for scrolling) that fortunately can be switched off.
• Decent battery life even with a 6-cell.
• Nice full-sized keyboard with fair displacement, good tactile feedback and a satisfactory click. I could almost forgive Dell for the inclusion of a Windows key instead of a realistically-sized space bar.
• Mostly supported out-of-the box in Kernel 2.6.16; so far, full support for the devices I’ve tried has involved just a bit of recompilation
• Nice screen with fair brightness and I haven’t detected any dead pixels so far.
• Gets kind of hot, but not too much.
• Real dock connector barring the need to resort to a cheesy USB port replicator
• Somewhat dull gray-and-black color scheme, but it’s not pre ugly (for a business laptop).
• Built-in smartcard reader (shows up as an USB device).
• Built-in fingerprint reader with startup protection right after POST.
• Did I mention that it has a Trackpoint?
• Built-in WiFi and Bluetooth.
• Built-in Wireless broadband with US-centered overpriced carriers (No idea if any of the hardware options would work with some Mexican overpriced carrier, but there is an intriguing SIM slot under the battery anyway).
• Built-in accelerometer that might be readable under Linux. This might end my MacBook-lightsaber envy.
• Full Type-II PCMCIA slot instead of ExpressCard, so I can wardrive while I work.
• Four USB ports.
• Light sensor for automatic brightness adjustment.
• Windows Vista capable (*Heh!* Like I care…)
• Up to 4GB of RAM, if you dare sell your firstborn, your kidney, or your firstborn’s kidney to pay for it.
• A real parallel and -check this out- DB9 serial port.
• The inclusion of a TrackPoint is a stroke of genius.

Cons:

• It really could use a keyboard light (Why do manufacturers still refuse to include them by default? That’d be… what? US$0.05 for a white LED and a switch when bought in bulk? But nooooo…).
• Both the trackpoint and the touchpad have only two buttons (Unix types may note that there’s one button missing).
• The 9-cell battery protrudes 1.5in from the front of the laptop instead of going on the back like in IBMs, so it kind of gets in the way and looks very much like an aftertought.
• Those videos of exploding Dells still give me nightmares.
• Sorry… no built-in webcam, nor multi-format memory card reader, nor JVC or Bose speakers, nor translucent white lid. This is a business laptop, remember?
• No Firewire. In this era of Firewire-800 external hard disks that is a serious oversight.
• The system beep is loud and annoying. Scare-the-cat annoying. Wake-your-neighbours annoying. Get-hit-by-your-wife annoying.
• No built-in SVideo nor DVI, thought there’s both on the port replicator. Not much of a problem for presentations, but you really need the port replicator to use a decent LCD screen.
• The Dell USB keyboard is kind of awkward. I keep falling off the left edge, and I have trouble finding the ridges in the F & J keys for touch typing.
• Sparse to non-existent printed documentation. There’s no manual to ignore. You can get them online if you want them badly. The Service Manual looks interesting, tough.

BTW if anyone from Dell is reading this: please update the configurator for LatinAmerica. You cant’ save your cart. You can’t email it. You can’t even *bookmark* stuff for later perusal. The LA site is primitive, counterintuitive and sometimes even downright annoying. Basically, it got stuck in the 90s.
On the other hand, Dell service was good. Thanks and kudos to both Ivan Castillo -who walked me through Dell’s product line during the Expo- and to Jesus Naranjo -who took my order and was very patient with my obsesive-compulsive hardware demands. One week into it I still haven’t had need to deal with their tech support personnel (Fate has carried on like that for a bit longer) and I hope it stays that way. If they are 50% like their sales people then I have nothing to fear, and altough I have heard some horror stories about them I’m willing to give them the benefit of the doubt for the time being.
In short: Dude, I got a Dell!

After flickering in-and-out for a few weeks and then getting a misterious red tint, the IBM Thinkpad R50’s display got well for a couple of months before getting all flickery again and dying for good. It was the nicest display you could find in any laptop of its class, even tough it is rather opaque and has its share of glare. I called IBM Tech Support and they told me that I could send it to Guadalajara for service after paying USD$70 for shipping and diagnostics (the backlight’s out, what else is there to diagnose?). I called IBM Guadalajara and was told that I had to pay over USD$100 instead, which I paid up anyway. Then they promptly proceeded to lose my service order for a month, time in which apparently IBM finally managed to kick out Lenovo employees from their Guadalajara offices. After calling their new number repeatedly, I got in touch with them and they finally managed to ship me a prepaid box to send the laptop out.
Well, as it turns out they have to replace the display. Big surprise! Wanna know how much that’s going to cost? Over US$900, thank you very much. You may be aware that the price of the display is more than enough to buy an entirely new laptop of almost any other brand.
Well, let me tell you about brand loyalty: My first brand-new PC was a IBM PS/2 55SX in the early 90’s. I worked like crazy for an entire summer and the next semester to get my hands on a luggable P70. I even sided on microchannel against EISA during the bus wars. Overall, for over 15 years the IBM Thinkpads had been my favorite notebooks. And I advocated them everywere, because even tough they were *very* expensive, their quality was outstanding.
And up to the 600 line they were excellent. But the L series was terrible, the power brick and the laptop itself overheated a lot and overall had awful power subsystem glitches. Anyway -and against my wife’s warnings- I went and bought this R50 anyway just because bdelgado got me a good deal, but it came with a bad hard disk right out of the factory, has a battery that degraded incredibly fast (half the original lifetime in six months of moderate usage, and nowhere near the advertised lifetime to start with), had to have its motherboard replaced barely a month before the warranty expired and it still overheats and has glitches in the power subsystem.
And to think that I was already looking into getting a Thinkpad X41 right before the R50 crapped out.
So decided that I am not going to spend that much money to replace the display in an outdated laptop. Moreover, I’m not willing to keep pumping money into a company whose QA processes seem to have disappeared, and whose service has got so bad that they lose a service order for an entire month.
So, goodbye IBM. Or Lenovo. Or whatever manufacturer they sell out to next. And hello Dell. I just bought a Latitude D620 and I’ve started to document my adventures with it. I will keep all of you posted on that.
In the meantime it’s goodbye forever to IBM/Lenovo computers. Thanks for the memories, but I’m not looking back, and it feels really good.

A couple of months ago my (formerly) trusty iPod anounced its impending death and I didn’t listen. Sure, it hung up a couple of times, but it had done that before. When I tried to connect it to a PC to feed it the latest podcasts the PC hung up, but Windows machines do that, too. A lot. Later I copied an ISO image to the laptop under Linux, and it took an unusually long time, but I was tired and didn’t even think of taking a look to dmesg. When I whipped out the iPod to listen to some music during an 11-hour flight only to find out that the battery was dead –even tough I had charged it overnight– I didn’t gave much importance to the issue. I just forgot to toggle the hold switch, I rationalized. So when it definitely locked up with a whirring noise and the clicks that usually announce the death of a hard disk, it came to me as a surprise. I felt a cold sweat down my back as an exclamation point appeared on the screen, inviting me to visit the Apple support website.
*Then* I remembered that I don’t have a backup of my iPod.
Of course, my iPod has a copy of my entire music collection. Heck, the iPod *is* my entire music collection, since it has every track of every CD I have ever bought, including many that have been lost or stolen. On top of that, it has more that 5GB of podcasts, a few ISOs, an essential software collection and an encrypted volume with a backup of critical information. The data files didn’t worry me as much as the music, because most of them were just backup files, but recreating that volume was going to be bothersome at best.
Now about the music… I have spent countless hours tagging, classifying and pasting artwork and lyrics to my music. That really hurt.
The iPod got worse really fast. After following the instructions on the Apple website a couple of times to get it into disk mode just to be ignored by the PC in turn, the folder icon was replaced by the dreaded Sad iPod icon. That’s it for the iPod, i tought. I should have bought that 60GB iPod with the color screen when I had the opportunity, instead of waiting for an 80GB model that never materialized.
When I followed the instructions on Apple.com I saw that Apple is more than willing to replace my out-of-warranty 4G iPod –engraving and all– after I dutifully paid US$250. Or I could shell out a few more bucks for a newer model, and forego all the accessories I have bought over the last three years, which have cost a small fortune and none of which will work with a video iPod. Smart move, Steve.
So let’s move on to the other option: perhaps I can replace just the hard drive. *Mmmh…* They go for some USD$100 for a 20GB one, and about USD$130 for the 40GB I need. That’s about half the tribute to Apple for a replacement. So I started looking for other people’s experiences replacing a broken iPod HD, and came across a post detailing William Mitchell’s own encounter with the Sad iPod icon, a reference to Josh Highland’s experience replacing an iPod HD and a cryptic reference to “dropping the iPod” near the end. Josh’s instructions are pretty straightforward, but when I read the comments to his post I found out that apparently many people have had success reviving their iPod by smacking it. Now in my experience one thing is dropping and Apple ][ a few inches to settle the RAM ICs into their sockets, but smacking an iPod to “realign” the HD head is something entirely different. I’m a trained Electronics Engineer. I am a member of the ACM. I *know* that this is not the way things work. But since the HD was dead anyway I decieded to give it a try.
I read the instructions again. No, there was no mention of any blood sacrifice or any other form of dark magic that could compromise my soul any further. I toggled the hold switch exactly ten times. I took the iPod with my left hand, and slapped the right side firmly. I turned the iPod on, and lo and behold: the whirring noise was gone, the clicks wheren’t there, and the iPod worked. My belief system was shaken to its core.
Now I can attest to the miracle.
I connected the iPod to a PC immediately and it was recognized. I spent a couple of hours looking for a program that could backup a selection of the songs in the iPod — podUtil is nice but won’t work in advanced mode unless you register, and in basic mode a nag screen pops up every 50 songs or so. ephPod is still broken, and YamiPod is great but Smart Playlists don’t work. Everyone else want to set you back at least US$19 for the privilege of backing up /your/ music from /your/ iPod to /your/ computer — a feature that iTunes should have in the first place. What the heck. I just plugged it into a Linux box and rsync’ed the entire partition –including the entire iPod_Control– to the storage server. It complained with I/O errors in a couple of files, which were promptly dd’ed with zeroes just in case the HD controller is able to reallocate those bad sectors. I entered the diagnostics mode and ran a HDD scan which the iPod passed with flying colors. And it is still working and merrily pumping out music as I write this.
The lessons I learned: Smacking stuff to make it work applies to high-tech gear as well, unbelievable as it may seem. Apple needs to provide an easy, intutive way to back up your music or move it between your iPods without resorting to third-party utilities. Throwing out backwards compatibility for consumer electronics is a smart financial move for Apple and its licensees, but it doesn’t make any sense for the consumers themselves. And finally the iPod is no walkman — you still have to back it up periodically. I should have known better.
So it looks that the iPod is fully functional again. I just *know* that the HD will fail again –probably for good this time– so I ordered a replacement HD anyway. But now I have my music and my tags securely backed up, so I won’t care as much when the iPod breaks again during the next worktour.
Update: In an amazing display of synchronicity, I just read Fate’s latest post on this same topic. I swear I had not seen it before, nor discussed this specific remedy with him (Actually, I still owe him a cup of coffee)… Perhaps there are no coincidences after all?

(*ack!* Wordpress ate my post!)

Live in Mexico? Have a TiVo? Read the TiVo-in-Mexico HOWTO to transform that glorified VCR into a real Personal Video Recorder.
Update 20051009: I just bought a TiVo 2 unit and it’s on its way, so I’ll update the HOWTO within a few weeks.
Note: This post was originally listed under the static TiVO page, but I’ll start managing the TiVo section with WordPress.

To change your TiVo’s timezone and date/time follow these steps:

1. Get timezoneadj30.tcl. I don’t have access to tivo_canada’s archive, so I had to write my own timezoneadj30.tcl.
2. Edit it and change the timezone. It seems that 0=GMT,3=EST
3. Run ./timezoneadj30.tcl

   # ./timezoneadj30.tcl
   

4. Set the clock using settime, e.g.

   # settime 20031123025900
   # settime -rtc
   

5. I noticed that if you set the time back, the IR blaster stops working. I’m not proud of my solution:

   # reboot

I recently upgraded iTunes to 5.0 on Magda’s laptop and it decided to start speaking to me in Spanish. In my Thinkpad with Windows XP in english iTunes was still in english.
Magda’s laptop came pre-installed with Windows XP in spanish, but I have never had a problem installing an english version of any kind of software in it. So far, every iTunes version had asked for an installation language during setup, and stuck with that language forever. iTunes 5.0 is different: no matter what language you use during setup, it will move on to the system locale whenever you run it. I bet that somebody in Cupertino believes that this is a “feature”, but actually iTunes is ignoring an explicit user setting, a usability do-not that comes as a surprise from the UI gurus at Apple.
Just to state a fact, I’m no Malinche. I write and speak an above-average Spanish, and I do love my country and its language. But I like my english software in English, and I do not have to endure the work of some underpaid english-to-spanish translator that can’t speak either language right nor understand their respective subtleties. Besides that, the iTunes ES translation is not for Spanish but rather for Castellano, and some strings are somewhat annoying. “Party Shuffle” sounds nice. It has a festive tone to it. When iTunes is in Party Shuffle mode my subconscious thinks I’m at a party, even if it’s 2am in the morning with two deadlines to meet early in the day and a senior programmer on vacation. In comparison “Sesión aleatoria” -random session- sounds just plain boring.
Today I upgraded to 5.0.1.4 half expecting this bug to be gone, but surprisingly it is alive and well and sends best wishes to everyone back home.
A quick google search got back an interesting result on Playlist Magazine’s forums: just close iTunes, go to its installation directory under “Program Files”, find every directory named <offending language code>.lproj (for me that was es.lproj) under iTunes.Resources, iTunesHelper.Resources and iTunesMiniPlayer.Resources and nuke them out of existence. The one under iTunesHelper.Resources might complain about a DLL being in use. Just move that DLL to some other place and delete it after a reboot. The next time you run iTunes it will talk to you in English.

Last night I got to play with ibm-acpi for a little while. It was refreshing to watch the backlight on the R50 go to sleep after being continually on while running on linux, thanks to radeontool and ibm-acpi’s magic to intercept Fn-F3. Priyadi Iman notes that ibm-acpi is included in kernel 2.6.10, but I’m still running the Ol’Thinkpad on 2.6.9, so I will have to play around with a newer kernel and report back my findings.
