Dead Kindle
My Kindle just gave up the ghost. As you can see from the image, the failure mode is a strange one: it's not that I cracked the screen or did any physical damage, the screen just locked into a big black section and a black band, and nothing I could do would unwedge it. Even Amazon's tech support was stumped.
To be fair, this Kindle lived a hard life. It sat in my saddlebag as I rode across France, and got used extensively all through our two month Australia trip. I've dropped it (and there's a chip on the side where it landed) on cobbles in France. Portable electronics don't last very long under the best of conditions, and what I put it through, while not a torture test, is still pretty harsh. That's no excuse though, my Blackberry survived pretty much all the same trips plus a few more, and was still going strong when I replaced it because my employer switched providers.
Amazon's replacement policy for out-of-warranty Kindles is that you pay $180 for it. Given that used Kindle 1 units still sell for around $300, and an estimated of Kindle 2's manufacturing cost comes out to $185, $180 is a very reasonable replacement cost. I asked if I could pay an upgrade fee and get the Kindle DX, but no dice, despite the fact that at the time, they didn't project having a Kindle v1 in stock until July! (The DX ships on the 10th)
Needless to say, I didn't even consider the Kindle 2, since I consider it an inferior product to the Kindle v1, given the lack of an SD card slot and the non-user-replaceable battery.

Pictures from my first bike tour in Europe
![]() |
| Tour of Languedoc-Roussillon (Southern France) 1998 |
In 1998, Paul DuBois and I joined a retired history Professor, his wife, and two other cyclists for a tour of Languedoc-Roussillon, in Southern France. That was my first bike tour in continental Europe proper, and I thought it was a good idea to travel with someone who knew the area, and knew the language was a good idea. In particular, I thought it would be interesting for someone versed in history to tell me all about the area.
The professor had a lot to teach me, but none of it was about history. He found routes by using a Michelin map, but didn't do a great job of research, so we had several days of riding straight into a headwind, which was no fun at all. He found restaurants by using the Michelin guide, which was OK, but I've since learned that it was't necessary to even use one. His wife drove SAG and went ahead and got us hotel rooms every day, which was very nice, but it added quite a bit to the costs, though a side benefit was I got to borrow the car every so often to run out with my tripod and shoot cityscapes at dawn or at night.
Ultimately, though, what I really learned was that having someone else pick your itinerary for you is nasty, unless you really like doing what they like doing. We traveled through lots of historical places, but without the kind of context he had, I couldn't appreciate it. At least the cycling was very nice, but I had great days when I broke away from my group and met up with other random tourists who would introduce me to folks and we'd have conversations, short and shallow as they were, since my French was (and still is) no good.
Back then, I traveled with an EOS Elan IIe with a 28mm and a 50mm lens, and Fuji Sensia 100. Those pictures don't scan too badly, and having a tripod meant that despite being a better photographer now, there are many pictures I wouldn't be able to get today since I've given up traveling with a tripod for my light and fast tours.
One friend of mine mentioned that the best slides in this collection were the images of people. Looking back at it now, I have to agree. Enjoy!

Tour of the Alps 2003 Updated
I've been scanning old photos, and the most recent project was slides from my 2003 Alps Trip. Most of the pictures were taken by Lisa, who was stoking the tandem. The stoker position affords the opportunity to shoot lots of pictures on the move (in some cases down a major mountain pass!), and Lisa did so. My later Alps trips, while they might have similarly good pictures, almost never have photos shot on descents because I'm too busy bombing down the pass with both hands on the handlebars to even think about shooting.
So take a gander, if you haven't already:

Mountain Charlie Loop
Lea Kissner, Richard Gooch, and Eddie Kessler showed up at Lexington Dam around 9:30am, and we headed off for a ride up Old Santa Cruz Highway. It was cloudy as we left the house, but by the time the bikes were ready the sun was out. We rode a slow, steady pace up Old Santa Cruz highway and by the time we got to the intersection with summit road the fog bank was in from the coast. A quick stop at the summit store for some water, we then rode down Soquel-San Jose road, which was still as smooth and fast a descent as I remembered before turning off at Laurel Glen. Laurel Glen was a climb in the shady redwoods before descending down to Branciforte.
At the turn off from Branciforte onto Granite Creek road, Lea bunny hopped a bridge joint and ejected the water bottle from her newly purchased Aqua rack. We then rode into Scotts Valley, where soon after the climb into the city proper we spotted Eric Fetch's (AKA the bike doctor) bike repair truck parked in the driveway of his house. I suggested that Lea get her bike fixed right then but she thought it would be rude to drop in without notice, so we proceeded into Scotts Valley.
I don't usually eat lunch on this ride, but Lisa, Lea and Richard ganged up and talked me into a stop at Carlos', a mexican joint just past the Highway 17 overpass. The food was fast and plentiful, but I knew there would be hell to pay on Mt. Charlie Road after that. By the time we were done with lunch it was well past 2:00pm, so we headed on our way to Mt. Charlie Road.
The bottom of Mt. Charlie road is deceptively easy --- it's rutted and has extremely bad pavement but the grade is extremely gentle, which made me wonder if I had misgraded this climb. After the initial easy section that's lulled you into a sense of security, however, Mt. Charlie reveals its true colors in the form of several pitches of 13-18% grade, which is tough going on a tandem even without an enchilada and a taco weighing me down. The temperature which had seemed cool earlier now felt like it was really warm, because at 2mph you just aren't getting a breeze to cool you down.
Half an hour or so of grinding later, we made it to the summit and zoomed down to the stop sign a mile away, where Richard and Eddie were so tired of standing around waiting for us that they had decided to lie down for a nap. We then proceeded over Highway 17 again, descending via Mt. Charlie road and Old Santa Cruz highway back to Lexington dam for a total of 42.89 miles and 4300' of climbing, which meets the Western Wheeler standard of 100' of climb per mile of riding.

Review: Samsung SBH 500 Stereo Bluetooth Headphones
I recently switched from using a Blackberry Curve as my primary cell phone to my Android G1. The main reason: Bluetooth A2DP Stereo support.
The Blackberry Curve supposedly supports A2DP too, but the native media player didn't expose the feature, and I had to try a 3rd party player. The result was atrocious --- one track would use the headphones, and the next one would use the phone's speakerphone or just cut off completely. I would have given up at that point, but then I tried upgrading my android to cupcake.
The integration is easy: just pair your phone in the Wireless Settings to the SBH 500, and start the music app. That's it. It even does the right thing when a call comes in --- the music player pauses, you take the call, and the music resumes after the call is over. Sound quality is good. No, let me take that back. Sound quality is great! When I'm in the office or at home, I get no dropped notes (unless I strain the G1's processor --- then the music skips, but that's not the headphone's fault). Phone calls sound great --- even my callers comment on that! I'm not usually a fan of listening to music at work, but now I do, because it sounds so great, and I didn't realize how much the fact that my headphones had wires kept me from listening to music until I had these!
As a bonus, the charger for these headphones has the same charger tip as for my Kindle v1. The manual claims 10 hours of talk time and 10 days of standby time, and indeed, I have yet to drain the battery on it, despite only charging the headphones once a week or so.
The only complaint I have about the headphones is that they get a little uncomfortable after a couple of hours of use --- that's not a big deal --- I take them off and 10 minutes later I'm ready to wear them again.
Given that they're available used on Amazon.com for about $25 shipped, I think these are an incredible bargain. Recommended!

Review: The Steel Remains
I would have written a review of The Steel Remains in January if Del Rey had chosen to price the Kindle edition of the book at $9.99 instead of trying to price it like the hardcover at $14. As it was, since I had plenty to read, I simply placed a hold at my public library. Yes, Del Rey, you lost $14 of revenue because you mis-priced your product.
At this point, we all know what to expect from a Morgan novel: a super soldier, lots of explicit sex, and plenty of philosophy and violence. Well, Morgan throws us a twist this time: the universe is an atypical fantasy universe, the protagonist is a gay warrior, and while there's plenty of explicit sex, the violence is even more explicit, and as bloody as you would expect --- much more so than the usual cleaned up fantasy novel.
I mis-wrote. There were actually 3 protagonists, all relics of the past war with the Lizards 10 years ago. Egar the Dragonbane is now part of the Steppe nomads, a happy clan-master running an unhappy clan. Archeth, a deadly knife-fighter, now works for the emperor as a trouble-shooter, losing herself in drugs. All this ends when Ringil's mom shows up and guilts him into searching for a cousin sold into slavery. (As unorthodox a start to a fantasy story as you can find --- how many brave warriors have moms?)
The plot then multiplies and we dig into one mystery after another until it all comes together in a bloody finale. While it's not radical, it all makes for fun reading --- and Morgan, if nothing else, is a good enough writer to keep you occupied for a few hours. Recommended for those with a strong stomach. For anyone else, take a look at Altered Carbon and see if Morgan's to your taste. That's still his strongest work.

Review: The Lost Fleet, Relentless
The Lost Fleet: Relentless is the fifth book in the Lost Fleet series starting with Dauntless. They are meant to be read in order, so don't buy this book and not have read all the others in the series.
One of my biggest fears with regards to long series is that the series will never end (or Robert Jordan style, the author would die before the series ends --- even his successor is having trouble keeping the final volume of the series in one book). Fortunately, it looks like John G. Hemry/Jack Campbell is very disciplined and the series will end at the sixth book.
Unlike previous books in the series, this one doesn't center around relativistic space battle set-pieces. In any case, if I was impressed by Campbell's set pieces, Alastair Reynolds' Redemption Ark blew me away as far as creativity in space battles is concerned --- it's obvious that Reynolds was an astronomer/physicist while Campbell was a navy man. Instead, what we have is a series of intrigues, one of which centers around a mole/traitor on the flagship.
As usual, Campbell's handling of romance and relationships between men and women is shallow, but as an adventure story the pace is fast, your brain rarely needs to be fully engaged, and nothing is bogged down. Recommended as an airplane novel and not much else.

Working with your hands
The New York Times Magazine ran an interesting excerpt from a book called The Case for Working with Your Hands this past weekend. In it, the author expresses how directly working on a physical object is direct, honest and cleansing in a way that intellectual work (such as the deservedly maligned investment banking) is not.
To some large extent I agree with him, but I've also had exceedingly bad encounters with shadetree mechanics who wouldn't read a book or understand the principles behind them if it killed them. Here's an example: Bicycle Wheels. I started building them for myself after running into several issues with wheels built by bike mechanics.
What really annoyed me was that these mechanics always adopted a holier than thou attitude --- they would insist that what they were doing was correct, despite violating every engineering principle. Myth and lore would take priority over being correct and building solid wheels. For instance, mechanic after mechanic would insist that straight 14 gauge spokes were stronger that swaged spokes. They would insist that not tensioning the wheel up to maximum possible tension was better than doing so (even though wheel durability is directly correlated with spoke tension). I even recently got into an argument with a well-known wheel builder as to whether spoke prep/loctite was necessary for building strong wheels.
It was this kind of attitude that made me realize that no matter the myth/lore/experience of a shade tree mechanic (or even a reputable mechanic) --- someone who's a good engineer (even someone who's not a real engineer, such as a software engineer) who's willing to read up on prior art and apply himself really does make a superior mechanic, if that was what he wanted to do. So there's plenty of learning on both sides.
(And I have no doubt that investment bankers would make terrible mechanics)

Review: The Prefect
With Absolution Gap being such a big disappointment, I could not bring myself to dive into The Prefect right away, even though the library had delivered both books at the same time. Nevertheless, by the time I was half way through the novel, I found myself visiting the library's web-site and ordering every book Reynolds has written that the library has.
The Prefect revolves around Tom Dreyfuss, a policeman of sorts during the Yellowstone System's Belle Epoque. What's great about this setting is that from previous novels, we know the fate of the system, but since those stories took place after a major disaster, we never get to know about the Glitter Band before it became the Rust Belt. The setting, then, is both different yet familiar to fans of the series. Even better, Reynolds has to clue you into the setting whether or not you're an old hand or a new reader. Technically, this is brilliantly done, and a clear case of the author in complete command of his universe as well as the stories he wants to tell.
Set in a post-singularity world, the story begins with Tom Dreyfuss investigating a mass-murder --- someone has destroyed an entire space habitat. From there, the story proceeds to increase in scope, as Dreyfuss has to unwind plots both within and without the Panoply (the police force for the Glitter Band) that ultimately determine the fate of the system. All throughout, we get hints and names that are familiar to us from previous novels, yet none of that name dropping is an inside-reference --- Reynolds deftly ties it altogether, and we see that what we thought were side-references in previous novels can be seen as scene-setting for this one.
Amazingly, after my complaints of wooden characters in previous novels, we now see fully-formed characters. Dreyfuss is very much not a cardboard cut-out, and we learn to respect him. There weren't any obviously wooden characters in this one, except perhaps for the villain. The only real criticism of this book is that despite the initial setup as a crime novel, it really turns into a techno thriller in the end, as the author does tell you who the traitor is long before Dreyfuss gets to him.
Nevertheless, this novel is highly recommended, and well worth paying the $10.80 Kindle price for if you're too impatient to wait for the library.

Review: Soon I Will be Invincible
Soon I Will be Invincible is Austin Grossman's superhero novel. It is told from two perspectives: Fatale, who is the Next Generation of Warfare, a rookie superhero joining the New Champions a superhero team roughly analogous to the Justice league of America. The other narrator is Dr. Impossible, The Smartest Man in the World, the supreme villain who has fought with CoreFire, the Superman analogue all through his career. The chapters alternate between the two perspectives.
Being a novel, the book gets into the minds of the characters as they muse about their various predicaments. Unfortunately, Austin Grossman is studying for a PhD in English at Berkeley which means that it's very hard for him to make Dr. Impossible come off as a really smart person --- a novel that tries to get into the mind of a character has to pull off quite a bit more than a comic book that only shows the Villanous dialogue rather than quiet reflection. In fact, Dr. Impossible comes across as a self-pitying person who never quite gets the hang of villainy.
The plot behind the novel was extremely simple Dr. Impossible escaped from jail and a superheroes once again have to stop him before he conquers the world. All the cliches you can find in comic books are here, as Grossman doesn't find that he has anything to add to the genre except some meta-musings: for instance, Dr. Impossible is said to have malign hyper-cognition syndrome --- the politically correct term for evil scientist.
Unfortunately all the plot twists are telegraphed way in advance by the author, as if he was afraid that you weren't smart enough to figure out what was going to happen next. Even the ending isn't at all interesting because Dr. impossible doesn't seem to even know what to do when he has conquered the world. Oh wait, it is only implied that he might have known what to do if he did succeed. The novel isn't even courageous enough to take that step. All in all, although the novel is short and could be a fun read on an airplane or on a bus, I can't really recommend it over going to the source material, and hunting down a copy of Alan Moore's Miracleman (the paper books run on ebay for hundreds of dollars each, but I'm sure you can find electronic copies if you look)

Short Mt. Tam Ride
This ride really took it out of me. Despite being short, the day was well over 90 degrees by the time we started riding over towards Fairfax, and the tandem makes all climbs about twice as hard. Mike didn't have much trouble and was quite strong at the end. Definitely needed to eat more ice cream!

A Quick Tutorial on ND grad. filters
Now that I have sample photos up, I can discuss ND graduated filters, which are my favorite tool for serious landscape photography, so much so that I feel naked without them when I'm on a serious photography trip. As described earlier, the fundamental problem of photography is to be able to render a scene that your eye can see into one that the digital sensor and your monitor (or print) can present.
Since slides and monitors can present about an 8:1 contrast ratio between the brightest and dimmest section of an image, while your eye (because it moves constantly and your brain composites all those images with no effort on your part) can see about 1000:1 contrast ratios in the same scene, you have a problem with a typical sunset or sunrise:
Note how the light (which your eye will render as yellow if you were there) is washed out, and the dark sections of the scene hold no shadow detail. (This is in addition to this film being shot by a point and shoot camera) The solution is to eliminate the dark portions of the scene through careful framing, and then placing an ND grad. filter right where the cloud-line would otherwise blow-out:
Now the light on the mountain looks closer to what you would see in reality if you were there. In the digital age, you can use Photoshop and Lightroom's HDR facilities to achieve something similar through multiple exposures instead of carrying $100 filters, but if the clouds in the scene were moving at all, for instance, you can forget it! One reason I converted over to Lightroom from my beloved Picasa is that you can apply an ND grad. filter after the fact in Lightroom (you must shoot in RAW mode for this to work --- storage is so cheap nowadays there's no reason not to)! This is huge, since even if you habitually carry ND grad. filters, what this means is that you get effectively 2 more stops of additional filtration after the exposure if that's what you need.
When in doubt as to whether the scene requires the use of an ND grad. filter, what you can do is to switch the camera to spot meter mode, and quickly spot meter the brightest and darkest parts of the scene. If the difference between the two is more than about 2.5 stops, you need an ND grad. filter. To decide how much filtration you need, figure out the difference between the highlights and the shadows, and subtract 2.5 (or 2 stops if the arithmetic is hard) from it --- this is how many stops you need. I usually carry both a two stop and a three stop filter, and can combine the two to create a five stop scene. If you're shooting RAW digital, you can be off in this calculation by about two stops, since Lightroom will give you that much leeway. (If you're shooting slides, you better be exact, or spend more film and bracket)
A really important tip about placement of the line in the view-finder. It is essential that you stop down to shooting aperture before placing the filter! Where the line on the filter is changes depending on your shooting aperture, which is one reason why the SLR is a superior tool for serious landscape work than a TLR or a rangefinder camera. This is why even though you might be able to use a polarizer on a compact point and shoot, it will be difficult to use an ND grad. filter on one --- there's no way to see the shooting aperture.
Another place where ND. grad. filters are useful is in reflections:
Not all the light hitting the water bounces back in the direction of the camera --- some of it goes into the water as well, and as a result when you try to take a picture of a reflection, the reflection often looks too dark. The solution: an ND grad. filter with the gradation line placed right where the reflection is.
Graduated filters are not a panacea --- used wrong, they can look unnatural, and frequently there's not a good line you can use. But when faced with a high contrast scene (especially those wonderful alpenglow scenes that nature photographers love), they are indispensable, and well worth their weight in the camera bag.
An example of an unnatural look when an ND grad. filter is used. Notice the blue sky above the clouds but yellow below. Of course, unnatural doesn't always mean that the picture isn't pretty
Since slides and monitors can present about an 8:1 contrast ratio between the brightest and dimmest section of an image, while your eye (because it moves constantly and your brain composites all those images with no effort on your part) can see about 1000:1 contrast ratios in the same scene, you have a problem with a typical sunset or sunrise:

This is huge, since even if you habitually carry ND grad. filters, what this means is that you get effectively 2 more stops of additional filtration after the exposure if that's what you need.
When in doubt as to whether the scene requires the use of an ND grad. filter, what you can do is to switch the camera to spot meter mode, and quickly spot meter the brightest and darkest parts of the scene. If the difference between the two is more than about 2.5 stops, you need an ND grad. filter. To decide how much filtration you need, figure out the difference between the highlights and the shadows, and subtract 2.5 (or 2 stops if the arithmetic is hard) from it --- this is how many stops you need. I usually carry both a two stop and a three stop filter, and can combine the two to create a five stop scene. If you're shooting RAW digital, you can be off in this calculation by about two stops, since Lightroom will give you that much leeway. (If you're shooting slides, you better be exact, or spend more film and bracket)
A really important tip about placement of the line in the view-finder. It is essential that you stop down to shooting aperture before placing the filter! Where the line on the filter is changes depending on your shooting aperture, which is one reason why the SLR is a superior tool for serious landscape work than a TLR or a rangefinder camera. This is why even though you might be able to use a polarizer on a compact point and shoot, it will be difficult to use an ND grad. filter on one --- there's no way to see the shooting aperture.
Another place where ND. grad. filters are useful is in reflections:

Not all the light hitting the water bounces back in the direction of the camera --- some of it goes into the water as well, and as a result when you try to take a picture of a reflection, the reflection often looks too dark. The solution: an ND grad. filter with the gradation line placed right where the reflection is.
Graduated filters are not a panacea --- used wrong, they can look unnatural, and frequently there's not a good line you can use. But when faced with a high contrast scene (especially those wonderful alpenglow scenes that nature photographers love), they are indispensable, and well worth their weight in the camera bag.

Grand Tetons and Yellowstone Trip, September 2002
![]() |
| Grand Tetons and Yellowstone |
For the longest time I promised myself that when I had time, a fast computer, and a place to host photos, I would go back and scan all the pictures I have on slide film into digital format for display. Part of it is that in this digital age, no one seems to have time to show up for a slide show any more. The other part of it is that I like to have images up for instructional purposes as well, and some of those pictures I had back in the old days were especially good. Slide photography is the most demanding form of photography there is --- unlike with color negative or digital photography, there's no possibility of rescue from a bad picture --- you can't even crop! Everything has to be done before the shutter is pushed. In addition, the very best slide films were slow (Fuji Velvia is ISO 50, Kodak Kodachrome is ISO 25).
Now that I have a little bit of time and a fast computer, I'll start with my Grand Tetons/Yellowstone Fall 2002 collection. That was one of those photo-trips where everything came together --- the light, the weather, and my gear all operated in peak condition, and I was very pleased with the results. The camera gear was an Olympus Stylus Epic 35mm point and shoot, and I had both my Canon bodies with me: EOS-3 and Elan IIe, as well as my entire collection of lenses and filters. I did suffer a mishap though --- as a cheap-skate I was always camping whenever I could, and after a stint in the hot springs with the tripod, the next morning I'd found my tripod legs frozen solid! I had to sit in the car with the heater full on and aimed at the tripod legs to get them to unfreeze so I could use them! All in all, I shot about 30 rolls of film for a 2 week trip, of which 7 days were spent in the back country without the serious equipment.
Scanning was performed on a Canoscan 4000US slide/negative scanner. It works like a champ, but of course, even the comparatively cheap Canoscan 8800F nowadays will be fast and probably just as good. I had to buy Vuescan because Canon does not provide a 64-bit Vista driver for that old scanner, but even if they had, neither Lightroom nor Photoshop support TWAIN scanners any more anyway! It sucks to be obsolete. Fortunately, Vuescan is very good and well worth the $40 --- the scans are so clean that I only have to crop them and post.
In any case, click through on the link, click "slideshow", and enjoy the show!

Review: The Steerswoman
The Steerswoman is such an old book that it is now out of print. You can, however, buy the Steerwoman's Road, which contains the first two volumes of the series.
The novel starts in what you would think is a typical fantasy universe, with mentions of Wizards, no high technology, and long travel on foot, sail, and all the usual inconveniences. The story revolves around Rowan, who's a Steerswoman, a combination of sage and wise-woman who acts as a repository of information for the community.
At the story's start, Rowan stumbles on some interesting jewels at an inn and feels compelled to investigate further. Before long, however, she finds herself under attack, and the story proceeds then to investigate the world she lives in, which turns out not to be the usual straightforward fantasy world after all.
The reveals are well setup and put together intelligently, but the characters are perhaps a little wooden. Nevertheless, I'll be tracking down the rest of the novels.

Review: Absolution Gap
Absolution Gap is the last book in the Revelation Space trilogy of connected novels. The first two volumes were Revelation Space and Redemption Ark. You could read this novel standalone, but the universe would be a lot richer for you if you read those first two volumes before tackling this one.
Unlike the previous two volumes this one is a downer. Reynolds almost immediately wipes the slate clean by getting rid of characters we know from earlier novels. Second, he then provides a bit of misdirection by providing a separate plot on a new system known as Hela. As the two plots converge, we learn more about the nature of the planet, and how dire the fate of humanity is under the threat of the inhibitors.
Unfortunately, as warned by the reviewers on Amazon.com, the book has a bad ending. It's bad not necessarily because the plot is no good, but because after all that build up, the ending has nothing to do with either of the plot strands discussed earlier. It's as though Reynolds decided to pull a massive bait and switch. The science parts of the novel are fun and interesting, but I'm afraid even Reynolds can't hold a novel with just that. I can't recommend this novel as a result, though I think the overall series is still worth reading on the strength of the first two novels alone.

Review: The Science of Fear
The Science of Fear is a great book! It covers why fear seems rampant in this modern age, when life expectancies are longer than ever before, and wars seem less frequent than ever (though the 20th century was still the bloodiest in history, neither nuclear Armageddon nor famine became prevalent). The book covers all the elements of fear, starting from why we remember negative news better than we remember positive ones.
It then goes on to examine who has an incentive to make you fear the world. Product companies (such as security specialists) have an incentive to sell you a product, and by making you afraid (of say a break in), they make money. Politicians such as George H. W. Bush have an incentive to sell fear, because that enables them to stay in office. Finally, the media has an incentive to sell news stories, and the best news stories involve fear, since nothing else sticks in your mind like the latest disease or disaster, no matter how statistically unlikely it is to affect you.
The author also dissects why we are so vulnerable to such institutions and people preying on us: our brains aren't evolved for modern society, from photography to round-the-globe 24-hour news coverage, so while we're capable of driving at 65mph down the freeway, our brains haven't adapted to the idea that perhaps the fact that we spend all our time driving and very little time exercising is much more dangerous to us than that news story about the serial killer or what-have-you.
What I love the book is that it's not afraid to name names and debunk myths. The breast implants scare comes up early on, and he follows through with such examples as the primary cause for cancer (I won't spoil it for you, but I guarantee that it's not much of a surprise if you think about it). Even sacred icons such as Rachel Carlson are not spared from Mr. Gardner's research and analysis.
All in all, this book is highly recommended.

The Relay, 2009
So two weekends ago, I participated in The Relay. As part of the third Google Team, we ran 199 miles.
This blog chronicles everything that my team went through, giving pretty much a blow by blow account of the entire race. =)
Yes, we blogged on the run. Say yay, to mobile WiFi!
The race was more of a logistics challenge more so than a challenging run. As a bonus though, I got to run one of my favourite hills to ride up, Redwood Gulch. =)
Ironic, I never thought I would be running up that hill! My time for that portion fortunately is worse than my ride up it (50 minutes for the 3 mile stretch)
I don't think I'll quite do this again as it didn't turn out to be difficult and was just long stretches of waiting. It IS quite incredible to do this as part of a team though, and that I'll treasure more than anything else.
Review: Black Diamond Orbit Lantern
I bought the Black Diamond Orbit Lantern during the REI 20% off period. I actually spent some time debating between that and the Apollo, but decided that the lighter weight of the Orbit would soon meet my needs.
Prior to this purchase, I always used a candle or a Coleman gas lantern, but the Stephenson did not come with straps for hanging the candle lantern, and the Coleman always had problems with use inside a tent --- not only is it dangerous, but a topple could burn up your tent!
The Orbit is tiny. It weighs 5 ounces with 4 AAA batteries. Each set of AAAs will go for about 10 hours, which is more than enough for a 5 day backpacking trip during the summer, or 2-3 days in the fall. It is bright!. With it fully lit, the inside of the tent feels very much like daylight. (that's an illusion, since it only has a 1W LED) It's so bright that your see white spots for a bit after you stare at the lantern directly.
As a reading light, it is so bright that I had to turn it down (fortunately it comes with a dimmer switch). I found a great way to use it, which is to lie it down on the side and then read on my back with the book (or Kindle) held up in my hands. For extra battery savings stick a mirror behind it, and use the dimmer.
Needless to say, this light is highly recommended. I'm retiring all my candle and gas lanterns as a result.

Cazedero LDT

| From Piaw's Blog |
What a gorgeous weekend it was! Not wanting it to go to waste, I joined the Western Wheelers for the Cazedero Circuit rides, a combination of really gorgeous rides in Northern California, on the Sonoma Coast. I knew I was out of shape, but this ride told me how badly off I was. Two years ago, I did the E ride on Saturday, 85 miles and 8500' of climbing, and was surprised on Sunday by how easy the ride up Coleman Valley road was. This year, I did the C ride, 65 miles and 6500' of climbing and was exhausted, feeling a lot of lower back soreness from the climbing. Then Saturday's climb up Coleman Valley road was a slog, no question about it. I was just too tired to be frisky.
Nevertheless, with wild poppies abound and gorgeous coastal scenery, I can't complain. It's good to be able to enjoy California after spending so much time away.

Kindle DX a massive boon to travelers
I did not bother upgrading to the Kindle 2 because I thought it was an inferior product compared to the Kindle v1. Today's announcement of the Kindle DX, however, will likely have me digging out my wallet to pay for the next time I travel. It's heavier (8 ounces more, so it will now compete with my CPAP machine in weight), and bulkier, but has one major feature, which is PDF support.
For the traveler, that means all the lonely planet PDFs can be stored for searching when you travel. When cycling in Europe or backpacking through Japan, this is a massive weight and space savings over the paper books. I begged Lonely Planet a year ago for a Kindle edition, but now I don't have to wait.
I don't know when the newspapers and magazines will switch over to PDF content, but it's only a matter of time --- now you'll be able to get all those glossies with images, etc. In other words, if you're about to travel somewhere independently (i.e., not part of a guided tour), this will become an essential accessory for you.
