Dead MacBook Pro with Flashing Question Mark

I had the classic, well it worked when I booted, but as soon as I wanted to do real work, it dies problem. Basically, when I try to start the MacBook Pro now, I get the grey screen and the startup chime. Then it sits there doing nothing (I can actually hear the click as the hard drive tries to move). After about two minutes, a folder with a question mark comes up. Not good. Hope everyone is religious about backing up. (I’d recommend the “Simpletech”:http://simpletech.com/commercial/products/simpleshare.html that is just about $140 and works very well.

The mac is so graphical it isnt clear how to even query google. In this case it is called a “Flashing Question Mark”:http://8help.osu.edu/1244.html. The main thing you need is a System CD. Of course who carries one of these around (I will from now on!) and then you run the Disk Utility from it to see if you can uncorrupt the hard disk as “Apple”:http://docs.info.apple.com/article.html?artnum=58042 recommends. If you can not even see the disk then you do the PRAM reset described below.

Here is what I’ve tried as “Apple”:http://docs.info.apple.com/article.html?artnum=303234 recommends and I’ve learned some cool command keys too

# First reboot. Apparently, holding the Option key, Command key and the Power button down is the equivalent of Ctrl-Alt-Del in the PC world.
# Reset the PRAM which is the equivalent of the CMOS reset on PCs. You do this by hitting power and before the grey screen comes up you haver to hold the Option, Command and the P and R keys down. It then reboots and again and when you hear the chime you are done.
# Reset the Power Manager chip onboard by taking out the battery and removing from AC power and holding down the power button for five seconds

To see if it is really a hard disk, you can hold a different keys to get different things to boot according to “Apple”:http://docs.info.apple.com/article.html?artnum=303124

Press C during startup Start up from a bootable CD or DVD, such as the Mac OS X Install disc that came with the computer.
Press D during startup Start up in Apple Hardware Test (AHT), if the Install DVD 1 is in the computer.
Press Option-Command-P-R until you hear two beeps. Reset NVRAM
Press Option during startup Starts into Startup Manager, where you can select a Mac OS X volume to start from. Note: Press N to make the the first bootable Network volume appear as well.
Press Eject, F12, or hold the mouse (/trackpad) button Ejects any removable media, such as an optical disc.
Press N during startup Attempt to start up from a compatible network server (NetBoot).
Press T during startup Start up in FireWire Target Disk mode.
Press Shift during startup Start up in Safe Boot mode and temporarily disable login items.
Press Command-V during startup Start up in Verbose mode.
Press Command-S during startup Start up in Single-User mode.
Press Option-N during startup Start from a NetBoot server using the default boot image.

Alas none of these worked for me. I lose quite a few hard disks with laptops mainly I think because I travel alot and run them hard. This particular macbook has been running hard but it was powered down properly and so forth, so maybe just early mortality. I’m sure glad we bought Applecare.

Mac DVD Creation for Sony DCR-SR100 Camcorder

Who knew that this would be so complicated. The new “iMovie ‘08″:http://www.apple.com/ilife/imovie/ is supposed to do this directly, but the support is just awful if you are going to try it. Here are the list of bugs:

* If you are using the 16:9 anamorphic format. What is called widescreen on the camera, then when you try to import things, you get something that is low resolution. iMovie 08 appears to make this letterbox. So you go from 720×480 pixels to something that is 640×480 and you get black bars. This is a standard definition camera, so this additional shrink is just terrible.
* iMovie ‘08 itself appears to be very buggy. It crashes quite a bit. And when you try to choose Share/Media Browser, it grinds forever, literally an hour on a 40 minute movie and then nothing actually appears in the Movie Browser. The only way that I found to do it was to do a Export as a Quicktime movie, but this creates something that is even worse, you get a 640×350 pixel or so movie, so you are again losing resolution.
* iMovie 08 dropped support for creating chapters, so you actually have to use a new application GarageBand to add chapter marks. Also, I couldn’t find a way to change volumes on individual clips so this has to be done in Garageband. Sigh.
* iMovie 08 itself is quite bizarre, you have to be very careful when selecting, since just mousing over a clip does a selection. I’ve never seen any application work this way, but that means that selection has to be careful indeed.

Net, net, this is just a terrible way and a long way backwards. I wouldn’t use iMovie 08, instead, you should get iMovie 06 which remarkably is a completely different application. There is a rumor that you can download iMovie 06 for free from Apple, but I have not been able to find it. So here is the process to make a high resolution as possible movie with iMovie 06. You do need VisualHub to do this:

# Download Visualhub and shell out the $23 for it. It is worth it
# Plug your Sony DCR-SR100 camera into the USB port. You should see it appear as a CAMCORDER disk icon. Open that up and in a magic direction, you’ll find a whole bunch of MPG files.
# To preview these files, download VLC for the Mac and then play the MPGs. The ones you don’t want you don’t have to copy. Sony by the way has this database issue. If you just deleted from the computer, then you get a bunch of broken links in your camcorder, so instead deleted directly from the camcorder rather than deleting the hard disk file.
# Copy the files you want for your movie into a directory. Personally, I like to sort it by date, so the files that were made 10 August 2007 would go into /Home Movies/2007/2007-08/2007-08-10. While this seems ridiculous, believe me with a bunch of MPG*.* files, you’ll get confused really quickly.
# Start VisualHub and drag the MPGs you want to use for your video into it. Now select the DV tab and click on Force 16:9. Assuming you’ve shot anamorphic. That is a widescreen is layered onto a standard, you should see a distored image in the resulting .dv files. These are going to be huge by the way, 40 minutes of a DVD can take 8GBs of space.
# Now start iMovie 06 and create a project like /Home Movies/2007/2007-08/2007-08-10/My Movie 2007-08-10 again this seems repetitive but helps later. Close iMovie 06
# Now you start Finder and go to that magic directly. Select “My Movie 2007-08-10″ and right click and click on Show Package, this shows the files inside the movie project and you want to drag all the .dv files you just made into the Media folder.
# Now start iMovie again, iMovie now thinks that these .dv files are trash and asks if you should throw them away, you should just drag them all onto the palette at the right. By the way the reason to do this step is that if you just drag the .dv files onto iMovie then it actually makes a copy of all the .dv files and this is slow and uses lots of disk.
# Now drag the clips you want into the window at the bottom in the order you want
# Begin editing your movie, you can fix the volume, by clicking on the show time line and for each clip, at the very bottom you can select clip volume from 0% to 150% of what was recorded. Normally when I’m recording chorus or music, I turn it up some. Unlike many other editing applications you can’t see the waveform so you’ll have no idea if it is too loud and clipping or too quiet, so listen carefully.
# Now you need to remember to create titles with the title menu. The application is a bit wierd in that every time you add a title, it actually makes a new clip and adds the title rather than keeping the clips clean. This means you had really better be sure that you drop the title in the exact right place. Most of the other video editing packages I’ve used keep the title separate until render time, so beware.
# Now click on chapters and add them. You really want this for the DVD
# Finally save and you are ready to click Share/iDVD. Unlike iMovie 08, this doesn’t call a rerendering, literally the .dv files are stitched together so you don’t lose any resolution. This is going to take a long time. 40 minutes on my Macbook Pro took 60 minutes to stitch together a bunch of things into a single 8GB .dv
# iDVD will now start automatically, pick the theme you want and then drag the movie in. If you are using the magic location /User/USERNAME/Movies then it will appear in the browser on the right.
# iDVD has the concept of a drop zone so it takes a still or something out of the movie and adds it to the menu. Go to Auto Drop Zone and select that, it makes a pretty good choice. If you did this right, you should see a DVD menu with the words Movie and Chapter Selection on it.
# Now choose Burn to Image and this creates a .img file. You can mount this file to look at it and use the /Applications/Utilities/Disk Utility to burn it to a DVD. Save the .img file so you can burn as many copies as you want. The rendering by the way for this burn image also is very long as it is converting the .dv file into an MPEG-2 format file. There is no control over the encoding options (unlike TMPengc that I use on the PC), so a 40 minute video seems to take about 2GB so a single layer DVD stores about 80 minutes vs. 120 minutes if you use a specialized tool that does better encoding so beware.

As a complete aside, check out “Apple.com/downloads”:http://www.apple.com/downloads to get widgets and other junk although I couldn’t find iMovie 08. Some good things are Google Earth for the Mac, also in Widget land, check out the airline flight finder and also the

iMovie 08 lost Chapter Creation!

Apple software is really strange. iMovie 08 is a completely different program from iMovie 06 and you lose an amazing number of features. One big thing is the loss of chapter markets (!!!). You actually have to use an entirely different product Garageband in order to get them back as “imovie8.blogspot.com”:http://imovie08.blogspot.com/2007/08/how-to-add-chapter-markers.html explains

If we didn’t have this Sony DCR-SR100 which only iMovie 08 reads natively and if iMovie 06 conversion by Visualhub from MPEG-2 to DV didn’t look so bad, I’d have given up on it all.

Right now I’d have to say the best option for now is to keep using iMovie 06 unless you have some hard disk camcorder, then you should probably go to PC software like Sony Vegas.

High Quality MP3 CD Backup on the Mac

I normally use Exact Audio Copy on the PC to do my CD backups. This combined with the latest Lame binary usually results in incredible quality particularly at –preset fast extreme settings, so on the Mac, its a little harder. iTunes has an MP3 encoder, but if you want the really best, try “Max”:http://www.sbooth.org/Max/ which provides Lame encoding of your CDs.

It uses “Music Brainz”:http://musicbrainz.org to tag things. I use tritag to do this, but they also ahve a Tagger at MusicBrainz and there is a freeware one called “iEatBrainz”:http://jay.tuley.name/pages/software#ieatbrainz that appears to be better than Tritag in that it does a lookup automatically.

Invisible SHIELD for the Nikon D40x

Someone asked me about protecting the really nice 2.5″ screen on the D40x. “Invisible Shield”:http://www.shieldzone.com/item_description/NIKD40.html is something I use for all my cameras. It is really strong and light piece of plastic. Expensive, but worth it. I used to use for my iPod screens as well, but the new iPhone is just too beautiful to use.

As an aside, the screen size of the “D40x”:http://www.popphoto.com/camera_review/nikon-d40x.html and the “D40″:http://www.popphoto.com/camera_review/nikon-d40.html are identical.

iMovie ‘08 support Sony DCR-SR100

Had a chance to download iMovie ‘08 and it does indeed “support”:http://www.notebooks.com/2007/08/10/imovie-08-adds-support-for-hdd-dvd-camcorders/ the Sony DCR-SR100. It is a little wierd though, you can’t just drag the .MPG files into iMovie HD, instead, you have to turn on iMovie HD, plug the camcorder in and then it detects the camcorder. It then goes through a long process where it creates thumbnails and then imports. Importing takes quite a while so I suspect that it is transcoding the MPEG-2 files into something else.

I sure hope the picture quality is better than the VisualHub transcode into DV format and then import into iMovie HD ‘06. On the other hand, I find the new iMovie 08 to be a very strange video editing program. it is completely different from iMovie ‘06 and I can see why folks who are used to other editors won’t like it much. Personally, I still like Sony Vegas the best for editing. But maybe that’s because I’ve used it the longest. Also, the iDVD integration doesn’t quite seem to work. I had it work flawless with a video once, but for the latest Sony DCR-SR100 it doesn’t seem to work at all.

Blackberry Video

The new Pearl has video and mono sound. The new Curve has video and stereo, so not a bad video device if you can figure out how to encode for it. On the Mac, “the8thsign.com”:http://www.the8thsign.com/2006/11/22/encode-video-for-the-blackberry-pearl-8100-mac-edition/ has a freeware encoder called mencoder and then an automation script that lets you right click on any video and then encode for it. It does encode at 15 fps, so not quite fast and at 230Kbps for video with mpeg4 and 64Kbps MP3 audio.

The instructions are to:

# download “mencoder”:http://www.the8thsign.com/download/mencoder.zip
# download “Automator Workflow”:http://www.the8thsign.com/download/encode_workflow.zip which you put into the magic directory _/Library/Workflows/Applications/Finder/
# Unzip mencoder.zip onto your desktop, start /Applications/Utilities/Terminal and type “cd Desktop” and then “sudo mv mencoder /usr/bin”
# Find an AVI or video file and right click on it, you should see the Atomator Menu and “Encode for Blackberry”

New iMac is faster

There aren’t many benchmarks done, but the new iMac all-in-one is really very fast. It uses the new Santa Rosa chipset and also if you spring for it, they actually use the Core 2 Extreme 2.8 GHz as “Primatelabs”:http://www.primatelabs.ca/blog/2007/08/24-inch-imac-performance-august-2007/

| iMac | Processor | Geekbench |
| 24″ mid 2007 | Core 2 Extreme 2.8GHz | 3791 |
| 24″ Mid 2007 | Core 2 Duo 2.4GHz | 3243 |
| 24″ | Core 2 Duo 2.33GHz | 3049 |
| 24″ | Core 2 Duo 2.16GHz | 2898 |

San Juan Tides and Rosario Strait currents

Everyone seems to use Captain Jack’s as their tide table, but as usual, online, there are a zillion resources. “Saltwatertides.com”:http://saltwatertides.com seems to have a really great list. BTW, for Tuesday, it shows high tide at 3:52AM at +6.7 feet and a low tide of -1.1 at 11:39AM, so basically in the AM, there is an ebb tide towards the south in Haro Strait and then after 10:32AM, the tide goes north.

For the corresponding currents, “Mobilegraphics.com”:http://www.mobilegeographics.com/pugetsoundcurrents.html shows that Rosario Straits has a maximum current of -2.5 knots ebbing to the south at 10:32AM and that about 2PM, there is a slack and that the maximum flood is at 4:42PM.

I also like “Sailwx.info”:http://www.sailwx.info/tides/tidemap.phtml?location=5550 which has a nice map of the tides and the stations
