Technical comments on 3G limitations

Why Apple's iPhone Doesn't Need 3G - Seeking Alpha

...High bandwidth networks drain batteries. Power consumption of any chip increases according to the frequency squared. That means if you want your network to go 10 times faster, the chip inside your phone managing that network consumes 100 times the power that a slower chip would (It's not quite that simple because of different signaling techniques, but the overall principle still holds). This is why Steve Jobs has decried the power consumption of 3G networks -- that speedy signaling actually matters in a battery-powered device. So why don't European users see this power-draining effect today with their phones? Well, check out the Nokia message boards and you'll find that they do experience some of the effect, but that effect is diminished by the fact that Europe has a much higher density of cell towers than the US does. And since cell phones decrease their radio power output when signal strength is high, the frequency effect of 3G transmission is partially offset by the fact they can use lower power amplifier settings for their radios....

I suspect the truth is more complex, I'm don't think 802.11g is really 25 times more power hungry than 802.11b for example. Maybe 2-3 times, but not 25. All the same, I do believe there's relationship between energy costs and throughput, particularly if the underlying protocol is computationally demanding.

The iPhones bandwidth issues are not a part of my 9 essential iPhone requirements list [1]. I'm much more concerned about using the phone PIM features when there's no network available at all.

[1] I see Apple has addressed item #8. So they only have 8 more to go and they make their big sale.

Why I'll buy Leopard - next January

Nobody seems to care about this, but Apple cares enough to rank it fourth on their list of new Finder features, right after the also incredibly great "back to my mac" feature.

Apple - Mac OS X Leopard - Features - 300+ New Features

Back to My Mac
Connect to any of your Mac computers at home from any Mac on the Internet. Your home computers appear in the shared section of the sidebar. Just click and you’re in.


Instant Screen Sharing from the Finder
Start an interactive screen sharing session with other Macs on your network. Just select the Mac from your sidebar and (if authorized) you can see and control the Mac as if you were right in front of it. Change a system preference, publish an iPhoto library, or add a new playlist to iTunes."

This is going to hurt, because I'm sure Back to My Mac will require a .Mac account. So I'll be buying Leopard for two machines and getting a family .Mac account. Requirements, btw, are well in the scope of my G5 iMac.

10.5 will, of course, break EMC Retrospect Pro (the latest version actually works) and I'll need an update to my VMWare windows emulator. Happily the Retrospect server runs on my ancient XP box so I just need the client update.

I won't, of course, touch anything until 10.5.1 and until both Retrospect and VMWare's updates have been on the market for at least 1 month. I'm guessing January 2008 at the earliest.

I know Andrew will take the arrows for me.

Google/Picasa Web Album uploader for iPhoto 7

Google could have done a much better communication job over the past two months, but there's news of an updated Picasa Web Album uploader.

The web site says they now support iPhoto 4 to 7; the version commitment is a much requested improvement. iPhoto 7 comes with iLife '08, the blog posting here calls it iPhoto '08 (emphases mine):

Today's release of version 1.1 of the Picasa Web Albums Uploaders adds support for Apple's new iPhoto '08... this release installs and updates via Google Updater to ensure that you are running the latest version.

While our first release used a private API to talk with the Picasa Web Albums server, the new version is built on the public Google Data API interfaces and our Objective-C GData Library. This will make it easier for us to keep up with Picasa Web Albums' new features. For example, the iPhoto export plug-in now can convert keywords in iPhoto to tags in Picasa Web Albums.

Our goal is to keep the Uploaders as quick, straightforward utilities that make Picasa Web Albums readily available to Mac users. You can give us feedback about them at the Picasa Help discussion group.

The last bit almost sounds like an apology. The language of the post is a bit ambiguous, but it sounds like they've updated both the standalone OS X and the iPhoto plug-in uploaders. The Keyword to Tag conversion is much appreciated.

Update 10/27/07: Unfortunately, there's a significant regression in the new uploader. The old uploader concatenated the iPhoto Name and Description fields. The new uploader maps the Name to PWA caption and ignores Description. This behavior should be configurable, but, more importantly, Google needs to open source the uploader so users can configure it.

Update 10/27/07b: Someone who seems pretty knowledgeable responded to my Google Groups post. Their was real thought put into the design, though I fear the thought was misguided. It actually uses the Name field value if it's been changed, otherwise it uses the Description field value. So the behavior is going to seem unpredictable to many users. The author clearly is not an iPhoto expert, or he'd have known that Batch Update makes it trivially easy to set the Name value to a date or meaningful string with counter; so that edits to comments are an easy extension. This needs to be fixed.

Disposing of an old Apple Computer, Palm's "any mobile" recycling program, the Blackberry exchange and quality CRTs for the elderly

del.icio.us tags: jfaughnan, gordon, apple, palm, recycling

TUAW has a great article on donating and discarding an old Mac: How to safely dispose of an old Mac. I didn't know Apple would accept an old machine and/or monitor upon purchase of a new machine, so one strategy is to keep the junk in the attic until you buy a new one.

Which reminds me of a post I never finished. Palm may be a vampire leaching off pale customers and forgotten innovation, but they are trying to look less bad by indirect means:

Brighthand: Get Any Mobile Device Recycled for Free

... Palm's recycling program is completely free -- that includes the cost of shipping -- and takes cellphones and handhelds in any condition, from any brand and also any old accessories that go with it.

All consumers have to do is download a pre-paid mailing label from Palm's web site, or pick one up at a Palm retail store. This service is apparently only available in the United States....

The Brighthand article has links to directions for erasing PDA data.

BlackBerry has yet another option. They'll not only recycle your old phone/smartphone, they'll give you "fair market value" credit towards your new BlackBerry:

BlackBerry Trade Up Program

Take your existing wireless device and turn it into a brand new, slim and stylish BlackBerry® smartphone. The BlackBerry Trade Up Program gives you the fair market value of your existing wireless device to use towards the purchase of the BlackBerry smartphone of your choice.

If your cell phone actually works many local groups will take them for 911 calling (women's shelters, etc).

On the other hand, nobody wants pre-XP computer donations. Don't bother, that's a purely recycling project. A good CRT can still find a home, especially for people with visual impairments who suffer from the fixed-pitch LCD problem. I think a group that works with the visually impaired might be interested in those, or look for an elderly computer user.

Ok, so I've done my insignificant part for the environment. Now if I can only figure out a way to get rid of all those plastic baggies ...

When a feature really is a feature: iChat AV's mirror mode

Today I found that the Canon ZR-850 and the SONY DCR-HC96 camcorders (SONY has to be in its cradle), when connected to a MacBook with a firewire cable, will produce fabulous iChat video. I had thought this capability had vanished!

It's just what we need for our workgroup videoconferencing. I tested on printed material, and I had no trouble reading the print on the display ... except ... (emphases mine):

Audio/Video conferencing - XvsXP.com, Mac OS X vs. Windows XP

... iChat AV has a number of niceties. It appropriately flips local video left to right, so your own image will behave just like a mirror. When you plug in an iSight and open the shutter, iChat launches automatically. If you're listening to music in iTunes, it will stop when you accept an audio or video invitation. Any currently playing DVD video will either pause or mute, depending on your DVD Player settings.

iChat supports video-conferencing with up to 4 people (provided you meet the requirements - a minimum of a dual 800 MHz G4 to participate, and a dual 1 GHz G4 to initiate a chat session). Rather than having separate windows for each person, each participant is displayed in one window with their video streams angled to create the impression of sitting around a conference table. There's even a reflection below each video stream - very slick...

UPDATE: I deleted the portion where I then ranted about this mirror image stuff, because posts on Apple's Discussion forum confirmed - the recipient sees the writing correctly.

Also, once we had the results of this test, a search on 'camcorder' 'iChat' and 'conferencing' produced some helpful references. They're mostly familiar to me, I'd just thought there were no compatible camcorders left on the market.

Alt-click to download in Firefox

Alt-Click in Firefox to download the linked item.

Apparently, this is so old and well known it's almost never remarked on. I even vaguely recall when shift-click did this, maybe in Mozilla.

I can't be the only one that finds this a great time saver though ...

Scanning old snapshots: My current workflow

Recently I wrote about using OS X "Image Capture" for photo Scanning. I've gotten some praise for the results, so I figured I'd detail my current scanning workflow.

My goal is fairly quick image acquisition of about 3,000 low quality 3x5 and 4x6 prints. Speed is more important than quality. The very best images, probably less than fifty, will be rescanned using a high quality Nikon Film scanner. After scanning is completed the prints will be discarded but I will keep the negatives in a single large binder.

Scan output is, for now, manged in iPhoto. If Aperture ever allowed us to edit date metadata I'd use Aperture. [foul language censored]

I thought I'd be doing this using a sheet feeder, dropping the prints in and returning hours later. I can't find a decent one for working with prints; the only one I can find is the SnapScan and they've historically not imaged prints. I'm using an old Epson 1660 Photo scanner, but if my secret weapon continues working I'll invest in the Epson V700 -- if I do that I might try bulk film scanning instead.

My secret weapon is the combination of an 8 yo with a Lego habit, OS X "Image Capture", and Aperture post-processing. Ben is willing to work for low wages [1] and Image Capture is simple enough he can go through 20-40 scans while I work on an adjacent machine.

He scans at 400 dpi with no adjustment and the images are output as TIFF. The results at this point are mediocre.

When Ben is done I drop the TIFFs into Aperture and optimize one image: auto-level, sharpening, noise reduction and contrast enhancement with some mild color saturation adjustment. I then apply the set to all images. (I think I can save it as a standard setting but I haven't done that yet. iPhoto 8 can also be used in a similar way, but iPhoto 7 would be very inefficient.)

A few minutes later Aperture is finished. I quickly review the results but usually I'm done with the initial work. I then crop the images fairly extensively. Lastly I export as 98% JPEG and I delete the TIFFs.

The JPEGs are renamed using 'A Better Finder Rename', since Image Capture adds a counter to the string "Scan" I rename "Scan " to YYMMDD_RollNumber_# where # is the counter produced by Image Capture. YYMMDD is based on the date of the roll, and Roll_Number comes from the prints. The roll number binds the roll of JPEGs with the set of prints with the set of negatives. I don' t capture the actual print or negative number, the roll ID is good enough for my purposes.

I then drop the JPEGs into iPhoto and add ratings, date estimates, and comments. I choose one date for a range of prints and add it with a 1 minute separation using iPhoto's batch update. The iPhoto roll information includes the YYMMDD_RollNumber identifier. The five star prints will later be replaced by VueScan negative scans from a Nikon CoolScan V.

The resulting images are impressively better looking, on screen, than the original prints.

[1] Amazingly this is legal for one's own child. I should mention that once he can do this without my help his wages will rise to whatever he can get from the neighbors for their scans. Of course I could start charging him for the scanner...

Update: This article on scanning with Aperture is pretty good. Note that Aperture has a big date problem. You can't revise the acquisition date. True, you can set a date in the IPTC extended image creation date field, but Aperture mostly ignores that field value. I use Aperture for editing, but iPhoto for archiving.
