Review: The Tom Bihn Synapse 19 backpack

TBSynapse19_01

My single strongest brand loyalty is to Tom Bihn bags. They’re brilliantly designed, attractive, near-indestructible, and made in the USA. I describe them as the Apple of bags. My first was an Empire Builder briefcase that I got when I went to Trinity, in an attempt to save my spine from my high school habit of carrying every textbook and binder around on my back in a bag that weighed half as much as I did. I carried it all through college, but it turned out to be so spacious that it didn’t really solve the problem; I still carried around more weight than my shoulders could really support. But as Tom Bihn bags have a modular design, I was able to take out the Brain Cell insert, attach a strap to it, and use it as a minimal MacBook case. Once the 11″ MacBook Air came out I went fully minimal and bought a Ristretto (original style, it’s since been updated) and for the last three years have never carried more than it could hold. 90% of the time that’s all I need, but very occasionally I’ve wanted something more capacious. Then, a Hanukkah miracle: I now own a Synapse 19.

It’s a small, six pocket backpack with shaped shoulder straps and removable sternum and waist straps that, once adjusted, hugs the body better than any pack I’ve ever owned. Mine is the navy blue nylon with Iberian red Dyneema interior, as pictured in the front panel shots here.1 (Though there are many other options. You can even get the whole thing in Dyneema, which is thinner than the nylon but reduces the empty weight by 7%.) The back panel is padded with a breathable mesh overlay to keep your back from sweating, and all of the zippers are rubberized for water resistance. The main compartment is an open space with a 2/3-height elastic pocket along the front. There are o-ring anchor points for attaching keychain lanyards or modular organizers, and it has two pairs of webbing loops to which you can attach the cache with rails to turn it into a checkpoint friendly laptop bag. Traveling to and from Texas for Thanksgiving, I found it very convenient to not have to take out my computer when going through airport security. Instead you just slide the cache out the top of the bag and let the whole thing go through the X-ray machine.

TBSynapse19_02Directly in front of the main compartment is a tall, narrow water bottle pocket, centered on the bag so that it doesn’t throw off the balance when it’s on your back. I don’t carry a water bottle, but this pocket is also perfectly sized for a small book, e-reader, or tablet. I’ve been using it to hold my iPad Mini. The two side pockets are curved and positioned such that they can be easily access while the pack is being worn by dropping one shoulder strap and pulling it around under your arm. One side has sewn-in pen sleeves and the other has a soft, sueded pocket for holding something you don’t want scratched. The website suggest a cell phone, but I’ve been keeping my backup hard drive in mine. Both side pockets have o-ring anchors, as does the small front top pocket behind the logo. The bottom pocket is full width and deeper than it looks. I’ve been keeping gloves, a wool cap, and my unused straps in there.

So far I’ve used it as my only bag on an overnight to Madison, and as my under-seat carryon for my trip back to Texas, and its been perfect for both. Even when I was packing clothes and toiletries along with my computer for the overnight trip, I didn’t quite max out its capacity. That said, it’s still small enough that I’m not at risk for hurting my back again. It easily sits near my feet in a full car, and can hook across the back of a restaurant chair without tipping it over when I stand up. The weather hasn’t been conducive yet to wearing it while riding my bike, but it has been perfect for every other task I’ve thrown at it. It’s the best backpack I’ve ever used. (If this design is attractive but the small size isn’t a plus for you, there’s also the Synapse 25, which is 30% larger but has the same layout.)

Review: The Air-O-Swiss 7135 Humidifier

Screen Shot 2013-11-13 at 10.38.40 PM

Let’s get this decade of my life started off right. Let me tell you about my high-tech humidifier.

AoS7135The unit in question is the Air-O-Swiss 7135. It’s an ultrasonic model with a replaceable demineralization cartridge impregnated with silver ions to impede bacterial growth. It has programmable controls and a built-in humidistat, so you can set it to either run for a given duration, or to turn itself on and off to maintain a desired percent humidity. It also has an optional preheater so that the mist doesn’t lower the ambient temperature of the room.

I’ve been loving it. Once the weather here changed and I had to turn on the heat in my house I was waking up with sore throats, aching sinuses, nostrils that felt like they’d been packed with sand while I slept. I got nosebleeds, an infection, lost my voice. Things got better when I went out and bought a hot mist (boiling) humidifier as a stopgap measure, but that raised the humidity in my room so high that it got musty, and on very cold nights water would condense on the windows and exterior walls. With the Air-O-Swiss, though, I can watch the hygrometer display and see it adjusting its output to maintain the humidity where I want it. It oscillates, but my experience is that it manages to keep things stable plus or minus around three percent. Since it’s cool/warm mist, I can set it up near where I sleep and have the occasional lovely and ominous curl of mist roll silently over the bed and disappear in front of me like a ghost. I’m sleeping better, and waking up better, than I have in a long time.

transducer plateUltrasonic humidifiers work by using a transducer to physically separate water molecules into a mist. This makes it quieter than models that boil water, or evaporative humidifiers that use a fan to blow air through a wick. The downside is that since the mist is being mechanically created rather than produced through a chemical process like evaporation or boiling, the mechanism is indiscriminate about what it aerosolizes. The transducer is happy to vibrate minerals, microbes, whatever happens to be in the water into the air for me to breathe. There are varieties of pneumonitis that are actually known as humidifier lung. As I’m on immunosuppressive drugs, that makes keeping the thing clean of particular importance. Fortunately, this model makes it easy. It comes with a solvent and has an indicator light for monthly cleanings, but I do it more often than that. About every three days, actually, as recommended by the Mayo clinic. The mouth of the tank is wide enough to allow quick and easy water changes, and the base mostly easily-scrubbable flat surfaces. It even comes with a little brush for getting scale, which can harbor bacteria, off the transducer plate. So far, though, the filtration and demineralization features are good enough that in a week of operation I haven’t noticed any of the white dust that’s typical of ultrasonic humidifiers. Assuming I don’t ironically die of Legionnaires’ disease in the next couple of months, I’m very pleased with everything about the device.

The bad news: it costs $180. That’s on the very pricey side for a humidifier, and if that matters you could probably buy a less expensive one, a hygrometer, and a timer switch from a hardware store for less than the Air-O-Swiss. But if the all-in-one convenience is valuable to you, or you’re having a birthday and willing to ask for the kind of thing that you want but would never buy for yourself, then the Air-O-Swiss is great.

Review of THE RADIO MAGICIAN & OTHER STORIES by James Van Pelt

The Radio Magician and Other StoriesAs previously related, James Van Pelt kindly sent me an advanced copy of his forthcoming short story collection, The Radio Magician & Other Stories to review.  I decided that I would read the book straight through, writing a review of each story as I finished it.

“The Radio Magician” – The story that got me excited about this collection in the first place. This is a very sweet tale with a powerfully realized sense of place and time. It’s about a young boy nearly paralyzed by polio and his love of radio drama and magic (stage magic and real magic, the borders blur)—pretty clear as metaphors for empowerment go. But the heart of this story is the spirit of generosity running through it. This is a warm story, filled with characters who try to make things a little easier for each other, or if not easier at least better. “If we’ve got any magic, we should share it,” our protagonist is told, and finds his empowerment by taking that message to heart. A little gem.

“Where Did You Come From, Where Did You Go?” – A short short, which raises the question, is suffering which inspires great art justified? It raises the question, but given the length doesn’t explore it. More attention is paid to two high school senior protagonists who find that the question might be directly relevant to their future. The main idea of the story seems to be how terrifying it is to make the initial choices that will define one’s life. As a high school teacher, the author likely sees this terror first hand quite a bit.

“The Light of a Thousand Suns” – I had problems enjoying this story. It is largely nostalgia for an out-of-fashion fear: cold war style nuclear annihilation. It is self-aware nostalgia, so the fact that I am not of the generation that grew up being taught to hide under school desks wasn’t fatal to my enjoyment. Rather, I was thrown out of the story by the way suicide bombing is described as a magical ritual. By way of explanation for the magic that takes place in the story we are told that suicide bombers do what they do essentially to curry magical favor—a sacraficial magic model. Suicide bombing, from what I understand of the systems of control, manipulation, and vicimization that enable it and result from it, is too much of a multivariate human tragedy for me to accept it being used so flippantly. The bombers themselves are as likely as not to be disconsolate people manipulated by fanatics with a vested interest in perpetuating cycles of violence. I can’t easily accept a story about how horrifying nuclear proliferation is conceptually when that story is simultaneously glossing over how horrifying suicide bombing is in practice.

“Of Late I Dreamed Of Venus” – Centuries long terraforming of Venus by a woman who is an ultra-rich industrialist in sort of the Rod McBan (Norstrilia)/Randy Hunter (Timemaster)/D. D. Harriman (“The Man Who Sold The Moon”) mold; rich to the point that practicality is no longer an important consideration as she pursues her ambitions. (It occurs to me that in hard SF huge sums of money have long served as a stand-in for magic. These days I suppose it is huge sums of money or the Singularity.) Her wealth plus the availability of long term suspended animation allows her to pursue and personally oversee her goal of turning Venus into a paradise, and her secret goal of transforming her assistant into her ideal companion. She learns there are limits to what can be controlled. The thematic beats are heavily telegraphed and there are several extended dream sequences which are necessary for pacing, but whose content add little to the story. Still, I enjoyed it, especially the mechanics of terraforming and the details of how society has changed each time the viewpoint character awakens. The evolving Venus is well realized.

“Different Worlds” – a 10-year-old girl and her dog must care for her injured and delirious father in a world where aliens have conquered Earth to emancipate certain domesticated animals. Kind of reminds me of more diplomatically inclined versions of the probe from Star Trek IV, or the aliens in John Varley’s The Ophiuchi Hotline universe. Beyond the metaphor of the title which is explained by an anecdote the father tells, this seems a very straightforward tale. Or there are subtleties I managed to miss. I’d be interested to know if this story had a specific inspiration; it kind of feels like it is a reaction to something, though I can’t pin down what that might be.

“The Small Astral Object Genius” – I really like this one. A boy whose parents are separating throws all his time and energy into a sort of do-it-yourself space probe kit called a Peek-a-boo, pretty clearly inspired by things like SETI@home. But there is no proof that Peek-a-boo is not a scam, tricking kids into thinking they are doing science. Dustin, the main character, expresses a fierce credulity whenever the thing is challenged. Eventually he almost accidentally does something with the device that generates some publicity and alters his family circumstance. The ending has the form of a happy ending, but I can’t help but believe that it is really heartbreaking. Dustin is just as optimistic that things are going to start being better at the end of the story as he is sure that the Peek-a-boo is real. An adult reading the story suspects that he is more likely than not to be disappointed. Very light in tone, but perhaps the darkest story in the book so far.

“Tiny Voices” – Death and new life and funny talking office equipment. Set in a future industrialized nation, probably America, in which in vivo pregnancy has been eliminated and all appliances and tools have electronic intelligence and can speak directly to their users through speakers or through mental implants. An excellent story with some very effective humor and a simple but compelling scenario that I don’t wish to spoil. First story in the collection that has seemed to me to fire on all cylinders as well as “The Radio Magician” does.

“Lashwanda at the End” — A fine example of the “explorers land on a planet without realizing all the ways it can be hostile to them” family of stories, which I generally enjoy. In this story the hostile ecology is primarily vegetative, so it is sort of a more biologically rigorous version of LeGuin’s “Vaster Than Empires and More Slow.” But unlike in that story, the people in this story are not insane, though our viewpoint character is somewhat frantic, as he is having to confront death—specifically the death of a colleague he loves. He has lived for centuries via life extending technology, and finds the prospect hard to deal with. There is a nice subversion of trope in this story, which I won’t spoil. Very good.

“Where and When” – I’m going to give the central conceit of this story away, so now is your chance to skip ahead if you so desire. It’s a time travel story that attempts to solve the paradox problems by positing that it is only possible to time travel to “dead ends,” places where you can’t effect anything because you won’t survive. For example you can travel back to Hiroshima right before the bomb falls, because no “information” from that moment will be accessible by the future. It’s clever, but from a physical standpoint, the information content of the system is still changed when you add the mass of a new human body to it. What these rules prevent is not the perpetuation of information, but of agency. Which in turn suggests the existence of a physical law that is, essentially, a law of conservation of narrative – a concept that is to me even more far-fetched than time travel. That doesn’t keep it from being a fun concept, though I think the story kind of lacks the strength of its convictions by positing the existence of mathematical wiggle room that will allow the main characters to survive. At least, they think they can—I’d like it better if they were wrong. So, on the whole a pretty silly story, although it has typically strong character moments. (One thought that just occurred to me: story order may be working against my enjoyment here, as we just went from a fairly rigorous SF story to a very hand-wavey, light one. This story might seem weaker to a reader primed by the one immediately preceding it.)

“One Day in the Middle of the Night” – A story cleverly structured around making literal truth out of the self-contradictory lines of the rhyming folktale with which it shares a title. The story takes place on a sleeper starship on which the only people awake are two brothers who hate and want to kill each other. A suspense story of hunting and being hunted, I would only criticize it for not having as well visualized a sense of place as most of the other stories in the collection so far.

“Echoing” – A trucker who can barely see through the blowing snow, a suicidal young girl hiding from her family on Christmas, and a being of indeterminate species piloting a psychic ship across the galaxy share a linked experience of uncontrolled momentum towards a dangerous destination. Perhaps their lives are connected by the titular echoing of the psychic ship as its pilot loses control. All of them lack an element of control, but perhaps, barely comprehending what is happening, they can help stabilize each other. A structurally fascinating story.

“The Inn at Mount Either” – A miracle, when discovered, will be monetized. This story is a case of missing persons at a vacation resort that is a hub of alternate realities. And given that alternate realties come into play, a problem of missing persons can be hard to distinguish from one of mistaken identity. A very fun read. Excellent.

“The Ice Cream Man” – Many decades after the onset of a mutagenic apocalypse wherin all living things stop having children that are remotely like themselves, the universal appeal of confectionery makes Keegan the ice cream man the only person who has commerce with both the mutants and the remaining humans. And so he is the only one caught in the middle when the human community decides to abandon a “live and let live” policy and go on the offensive. A story of the factors that go into building a person’s identity, and of choosing sides. Simple and entertaining, with moments of profundity.

“Sacrifice” – The voice in this story is something of a departure from the stories preceding it, which is refreshing. That’s not to say that voice has been a problem, just that the novelty is nice. It is two young people from a fallen, post-technological human culture engaging in a sad ritual. But there is some remaining knowledge of their history that the girl has become aware of thanks to an offscreen wise old man character. In fact, the wise old man character is so wise that the disconnect between his knowledge of what is really going on and the institutional superstition of everyone else strains belief. Also, contains the book’s first sex scenes that I can recall, which are very well written. The story as a whole is pleasant, but difficult to really buy into.

“The Boy Behind the Gate” – I have a new candidate for darkest story in the collection. Here we have two parallel stories set in the same mining town, one in the modern day and one in 1880. Today a man is desperately searching for a kidnapped son he fears is dead, in the past a father is trying to work up the courage to kill a son he fears causes the deaths of other children. The two storylines move toward each other and eventually intersect, but neither father’s course leads to redemptive results. There is a great talent for setting on display in this fairly depressing, though well written, story.

“The Last Age Should Know Your Heart” – Sentient, poetry loving robots trying to reach each other before the heat death of the universe. Beautiful.

“Origin of the Species” – Mythological beings got diluted almost out of existence by mating with humans long ago. Almost. But their characteristics persist as recessive genes. So at the high school where the story is set, our loner point of view character is a little bit werewolf, the big dumb sexually experienced jock is a little bit troll, and it isn’t hard to figure out what the girl they mutually desire, Fay, is. The clever bit though is how the story plays off the way that adolescence seems mythological, every social success or failure an epic victory or tragedy. Here, the teenage years feel fraught with mythology because they literally are. The way the characters grow into their magical stereotypes seems the most realistic part of the story. A bit predictable, but fun all the same.

“The Saturn Ring Blues” – The title could easily fit an episode of Cowboy Bebop, and so could the content. Two ex-lovers take part in a race around Saturn’s rings. The main function of the story is playing around with voice and a blues-y idiom. Again, reading the book straight through, the novely of tone is refreshing, and while there isn’t a lot of depth, the story gets the job done and doesn’t overstay its welcome. Another fun one.

“How Music Begins” – Fabulous. A middle school band is trapped in eternal band camp by mysterious demiurges until they can produce the perfect performance. A richly nuanced story, probably even more so for people who have devoted their lives to teaching and spend their days seeing children develop into adults. Also has what I think is the collection’s first clearly homosexual character. It was starting to bother me that there hadn’t been one yet. The collection ends on a high note.

So, I liked a majority of the stories, which is pretty good for a large collection.  Thanks to James Van Pelt for letting me read it.  The Radio Magician & Other Stories comes out in September.
