iPod Photo Error -39

Just when you thought iPods were easy, you get an unknown error (-39) to remind you that these really are computers and you can actually still see a return code. In my case, this is the error my iPod Photo throws because of a bad file somewhere.

You mainly have to be careful with iTunes that you don’t *change* this directory otherwise you lose *all* of your photos. Be caseful, just switching from say My Photos to c:\pictures will wipe *everything* out!

I haven’t seen this documented yet, but I have 3,000 photos and 5,000 tracks (I know I’m a nerd!) to get onto an iPod Photo. That causes its own instability. In my case, I have found that:

* TIF files. The really massive TIF files don’t compress correctly. If you have a 200MB TIF, you get garbage in the thumbnails. Plus it takes iTunes an incredibly long time to read and compress. (BTW, I have these from full resolution 35mm scans).
* JPG files. I have one or two files that seem to cause major headaches for iTunes. Again, there aren’t any error diagnostics except that iTunes would crash and leave me with nothing. I did find out that iTunes leaves a special directory called _iPod Photo Cache_ in the root of the directory being synchronized. This can get corrupted if it doesn’t translate the JPG correctly. You then get the (-39) error. The fix is to delete the iPod Photo Cache directory and it trys to translate again. By carefully copying certain files, you can figure out what the offending photo is.

Longer term, you really do have to undertand iPod internals I’ve found when these crashes happen. There are two things to understand for photos:

* iPodlounge Forums – Photo Storage on the iPod photo — The Gory Details. This is a great explanation of the files on the iPod. The iPod acts just like a standard hard drive, there is a directory called \Photos that has a whole series of chronologically sorted directories.
* On the PC there is this big iPod Photo Cache directory as I mentioned above.

nVidia 6800GT Temperature Monitoring

Well I’ve got my new Pentium M system up and running and now running benchmarks. Right now, I can overclock it by about 22% so a 1.8GHz Pentium M is running at 2.1GHz right now.

According to Sis Sandra 2004 (I can’t get 2005 to run on this machine right now), I’m the equivalent of a 3.6GHz Pentium 4 desktop chip. Wow, that’s pretty amazing since this thing uses 20 watts and the CPU temperature is 40 degree C vs. 120 watts and much hotter. It still isn’t faster than an Athlon 64 2800+ overclocked to 2.45GHz, but I’m not quite done tweaking the thing.

The main problem is the incredible noise from the graphics card and the fact that the neither the CPU fan seems to temperature control nor does the case fan. Am getting a NV5 Silencer from Arctic Cooling, but the other changes are to install an Arctic Cooling 80mm case fan (easy to do since it the nMediaPC case is perforated at the top and also added a fan voltage control.

So how to tell what the GPU temperature is? Smartfan doesn’t do, this you have to use Rivatuner which has a monitoring program, or if you have the latest nVidia driver installed, right click the desktop and go to Display/Advanced/6800GT and select the Temperature monitoring option. My stock fan for the eVGA 6800GT runs at 55 degrees C at idle. I was able to turn down the fan manually to halve the noise volume and stay there.

There doesn’t seem to be a utility like SmartFan that automatically changes temperatures under load though.

just wondering which r the best programs for monitoring your GPU temps

TiVO

Rapid Satellite – Detail

What do you get with your UPGRADED TiVo?

Automatic recordings of your favorite shows without the hassles of videotape or timers. Watch what you want, when you can!
Because a TiVo is, in it’s most basic form, a computer hard drive, by replacing the internal hard drives of the standard TiVo unit and adding 2nd drives, we are able to exponentially add additional hours of programming and recording to your TiVo. The outside of the unit will remain the same… but the performance will blow you away. You still get the same great features offered with a standard TiVo unit.
Why settle for an average 35 hour DIRECTV TiVo unit when you can have 105 hours or even 240 hours?

McDonald’s: Want VOIP with That?. _Hat tip to “Bob”:http://bobsplanet.com for pointing this out._

McDonald’s: Want VOIP with That? They are using a VOIP system so that they have centralized order taking for the drive through line. Classic queueing theory problem. Instead of having 1 person for every store, you have six people for nine stores.

New has NV5

Newegg.com – ARCTIC-COOLING NV SILENCER 5 Fans, Heatsinks (Case, CPU, Chipset). OK, here is where you can get the cooling system. You need thermal paste too.

Rich Hits

OK, sometimes I wonder about the Internet. Two funny stories in the last 24 hours:

“Robert”:http://www.ignitionpartners.com/about/robert_h.asp was looking for information about handset shipments. And “Tongfamily”:http://tongfamily pops up as the first hit.

“Steve Holcomb”:http://fullcapture.com/leadership_team.html was looking for Acura MDX information and again this site pops up.

How amazing that this crappy little site actually has a high level of hits for things. Cool.

Arctic Cooling VGA Silence NV5

NV5 Review. This is a $28 after market fan that is supposed to be much quieter than the stock nVidia fan. The main thing is that you have to remove the fan unit and install this thing.

DFI 855GME-MGF

Finally got my first HTPC to boot. Main issue was a documentation one, which is that when you put the CPU in, you have to half turn a little screw otherwise, you put the whole thing together and it doesn’t boot!

See GamePC – Are You Game? – Dothan Delight : DFI’s 855GME-MGF Pentium-M Motherboard. The Socket-479m (mPGA-479m) CPU socket which the Pentium-M processor utilizes is a standard beige color (compared to the dark gray variant which AOpen utilizes). The CPU socket can be opened and closed with the use of a slim flat heat screw driver.

So how does it look so far? Well main problem right now is that I stripped some of the wires when I took it apart and these little connectors are tiny. I loosened two ground connectors for firewire and for usb 2.0.

Other thing is that the nVidia 6800GT is a *loud* card, its fan swamps just about everything else. Other issue is that the front panel doesn’t light. I think I have to tie the CPU fan to the front panel for it to report out.

Thanks to the folks at “Madshrimp’s Forum”:http://www.madshrimps.be/forums/showthread.php?pagenumber=1&threadid=11305 for figuring this out.

Final aside, Dan asked me why I’m playing and installing machines when you can get prebuilt. Main answer is that it is fun to hot rod. Clearly it is not economic to build your own computers and maintain them, but it is certainly a fun thing to do.

Future of Home Theater

Well, CES is over and the “honorees”:http://www.cesweb.org/attendees/awards/innovations/rd_honorees.asp are in, so a good time to reflect on the future of the home. Its interesting to see what has and hasn’t happened. Right now, the home entertainment business reminds me a lot of minicomputers in the 1980s (Ok, I’m dating myself!). That is, lots of standalone boxes that can do everything. Microsoft is the IBM giant with their System 36 and AS/400, big and most share and highly intergrated. Digital Equipment Corporation feels much like Apple, they are stinging like a bee and moving around, but essentially with designs to be the next IBM in terms of being totall integrated.

So what could be the left hand turn here? Well, I’ll go out on a limb and say that this feels much like the music business in the mid 1990s. Back then, all the talk was about protectable content, etc., and I remember thinking as I ripped my first CDs that this just isn’t sustainable. It is just way to easy to copy things and it is so convenient. Now it did take a decade for things to mature to the iPod today, but I wonder if the same thing isn’t going to happen with video.

Right now, the hearty are using Tivo (reminds me so much of the Apple II to strike another analogy), but the excitment for me is in “Bit Torrent”:http://bittorrent.com and in “Isohunt”:http://isohunt.com. They are horribly hard to use, etc., but it is way more convenient.

So here’s one way to think radically about the home and video. Suppose there are the following pieces:

* The PC. Also known as its OK to use a keyboard. The home is really different from mobile. A keyboard is one room away. So why can’t I select an entire stream of video and then just watch it anywhere. It’s the playlist analogy. Now everyone at this point will say what about digital rights etc. I agree these are big issues, but fundamentally because
* The TV. To me, this is more about what you can do with a 9-key remote (ideally, 9 keys plus 5 buttons, but more on that in another post about user interfaces). The idea is that you should make it easy to take the “playlist” you have from the PC and then watch it. Personally, I’m less of a believer in this EPG like world, where you have to adapt to what is on and more of a believer in the, you should watch what you want to watch when you want to watch it. If you don’t like it, then you should be able to iPod-like skip fast. Most folks are very good at browsing lots of stuff and skipping quickly, that’s why skip is promoted to a top level button in most interfaces from Blackberry to iPod. I’m also a believer in the idea of shuffle. That’s not a bad way to think about, it if you just to lie on the couch and watch, then pick the things you like and shuffle away. Now live content is a little different in that you don’t pick but same idea applies, make it easy to channel surf. The best demo I saw was the Dish network, see 9 live feeds at once. I think people are super good at scrolling quickly through content. Witness the simplicity of the iPod Photo. I have 3,000 photos on mine and I’m amazind how easy it is to just scroll through huge lists if the machine is really keystroke fast.
* The Internet. I love netflix. To me, that’s a way better model than this Tivo, find a program and then record it all. The content is in nice chunks, you treat people like adults who know how to use Keyboards. Another analogy is that 90% of our movie watching is what “United Airlines”:http://united.com shows. Turns out that these shows are just perfect for our house (not too violent, lots of romantic comedies etc.). That’s the iMix of our house and you can see the analogy in the wonderful future world. With RSS and Blogs, I should literally be able to subscribe to what “Ludwig”:http://www.ludwigs.com is watching.
* The Home Network. The world seems to be filled with loosely coupled standalone devices. Seems to me that the right world is one where you insert a new device into the network and like enterprise computing’s push to the grid, you get the same thing at home. When I put a Mac Mini or a PC in, then I get its hard disk as part of the virtual hard disk. I shouldn’t have to manage all the video and music everywhere. Similarly, any device I plug in shouldn’t require some expensive set top box, but it should just have Ethernet and you plug it in. Same for displays, you should be able to plug a display in anywhere and every input and disk is available.

What are the implications of this:

* Channels. Someone said, what’s a channel if you can select exactly what you want. That’s my Bit Torrent experience exactly. I just want to see the shows and shuffle them for me.
* Digital Rights. There is alot of locking on stuff right now, yet eventually, it all has to appear in analog form somewhere and there are always going to be digital camcorder lurking about. Maybe the first copy won’t be full fidelity, but everyone after that will be, so that means that the first folks who make things easy and reasonably priced are going to be big winners.
* Text entry on distance viewing. Probably wrong, but it does feel like you enter on a keyboard and then view/surf in the family room.

So who is working on things in this area. Some interesting companies are ideas came out of CES. I just picked CES winners:

* Meedio – Media Center PC And Automation Software For The Digital Home. This came out of the myhtpc effort and is now a commercial product. They have three products. First an EPG (electronic program guide) that make it possible for any PC with a OTA or cable tuner to be a DVR and record shows. They also have a viewer that lets you have a simplified user interface so you can use a TV and remote with your PC. Finally, they have a bunch of home control widgets so you can turn the lights on and off. And there is a development environment so folks can writes applications and drivers around their user interface.
* “Snapstream”:http://www.snapstream.com/. These folks have similar offerings, they have an EPG and a DVR for your PC. They also have a distance viewing user interface and then a way to have other PCs look at recorded shows.
* “Tivo”:http://tivo.com/. The early market leaders, they have a DVR and an EPG and are well known for simplicity. You buy this as hardware plus either a monthly subscription to the EPG or for $250 you can buy it forever. They have a deal with DirecTV that integrates DSS and a HD DVR, although this device (the 921) is expensive and phasing out as DirecTV is going to build their own.
* “MythTV”:http://www.mythtv.org/index.php. This is the Linux version of the above.
* “ATI”:http://ati.com/products/tvwonderelite/index.html. From their first Wonderboard, ATI has been building hardware cards, the latest called Wonder Elite
* “DVR”:http://dvr.sourceforge.net/. An open source project to do the same.

There are lots of places posting about this including:

* “PVR Blog”:http://www.pvrblog.com/. Well named blog focused on the travails of Dish these days.

Future of Video

isoHunt – IRC and Bit Torrent Search Engine. It must be me, but as I’ve been to CES and heard about all these electronic program guide, I have to admit for HTPC or PC viewing experience, I’m not sure that I get it.

There seem to be many pretty interfaces that I’ve tried (Comcast/Gemplus, DirecTV, Dish, OnCommand, etc.), but while this might work for 9 key remotes, for something that is high resolution and also has a keyboard, I’m a little confused why the search metaphor doesn’t work.

In fact, I could argue that there are a couple of current Internet user experiences that could be video on deman tomorrow if you are talking PCTv experience (e..g, not distance viewing):

* “Netflix”:http://netflix.com. Instead of saying rent the DVD, just download it.
* “ISOHunt”:http://isohunt.com. This is just a search engine or maybe the new google video service. It just does searches and then uses a Bit Torrent compatible client like Azureus to do the download.

For me anyway, having a new HTML tag like vod: makes more sense than a custom guide world.

Things are different in the DVR world where you have to work with a limited remote of course. FWIW.
