First Impressions: Garmin Edge 830

Last year in June, Bowen saw me, Mike, and Arturo use "GroupTrack" during our bike tour in the Shasta region. After he saw that, he asked for a GroupTrack capable bike computer. I contended that he didn't need one, but he kept persisting, so I told him there were only a few ways he could get one: give up his other birthday presents, get one of his friends to go touring with us, pay for it out of his own pocket, or ride his single bike to school every day for a year.

Well, he rode his single to school every day, rain or shine, and then in March COVID19 effectively ended the school year for him. I could have gotten him an Edge 520plus or 530, but I figured if I was going to get him something it might as well be a navigation-capable unit for backup when touring, though who knows when we'll get to do that, so the Edge 830 it was.

The main reason is that the Edge 830 was faster (which is a big deal if you want the GPS to do the navigation and routing), and also the trail forks integration, which is useful potentially for mountain biking. (Though around here, it'd be rare that I ever got lost on a mountain bike ride!)

The unit is indeed super-fast. It does everything far faster than my Fenix 5X, which was already too fast for me to keep confused. It pairs to a smartphone for GroupTrack, which is as reliable as you can imagine (not very), but sometimes does do a passing job. It does require that your phone has a data plan, etc, so some of it is that I'm not spending big bucks on Bowen's data plan.

Unlike his older Edge 25 (which now goes to his brother), the Edge 830 does a fabulous job sync'ing rides up to Garmin Connect even over WiFi. The Edge 25 despite its claim to doing bluetooth sync'ing, never actually did so and I'd always had to plug it into a PC to get ride data out. It also links to power meters, which is kinda funny on a triplet.

All in all, if you had to buy a navigation-capable bike computer today, this is the one to get. It's a huge improvement over the older units, and worth the money (especially since I managed to use a 20% off coupon on it). Recommended.

Review: Godox TT350P

I've been using the Ricoh GR3 on many of my adventures recently, and the lack of a fill flash on the camera started to bug me. Without a fill flash, many daylight pictures turn into a mess of shadows, which is only partially rescuable using Lightroom. Almost as importantly, the catchlights in eyes look which I love can't easily be achieved as well.

All the official Pentax flashes were too expensive and/or heavy for what I was trying to do, so I went looking for an unofficial solution. The Godox TT350P seemed to be extremely good value: it comes with a stand and a diffuser (something I've always had to buy for my Canon flashes separately), a case (which is useless), and a fully rotatable head (for bounce flash). The flash is heavy, however, about the same weight as the camera it would be attached to.

My first experience with the flash was disappointing, however, with clear flash artifacts that I wasn't happy with.  The results were inconsistent, occasionally over-exposing the photo, and occasionally looking as though the flash wasn't on. It's quite clear that Pentax/Ricoh's TTL integration isn't even close to what I was used to with Canon's, where simply dialing in a -2/3 or -1/1/3 flash exposure compensation would get you picture perfect results. However, the Lightroom "Flash" auto-correct setting did the right thing on occasion, and while the artifacts are still there if you know how to look for it, they're not completely unnatural:

And I got the catchlights back:

After using it on a few hikes and bike rides, I decided that the flash was just too big. If I'm doing a difficult trip, I'd rather use the weight budget on carrying more food, water, or the hammock. If I'm doing an easy trip, then I might as well carry the EOS M6 instead of the Ricoh GR3 and the flash. I reluctantly returned the flash.

Reread: Dune

I found myself rereading Dune, and years after my first reading of it in my teenage years, it's still and astounding novel. Things jumped out at me this time that didn't in my first reading. For instance, it's astounding how for a science fiction world how medieval the institutions in the novel are. Even the position of a planetary ecologist is via inheritance, rather than merit. All the major characters are characters born into privilege with a huge amount of attention given to eugenics, and training is only available to those of a high born class.

It's also amazing to me how much various parts of the book affected my psyche through the years, even though much of it was forgotten. I remember driving home from the hospital with Bowen and Xiaoqin, suddenly aware of how every careless driver was suddenly a threat. I didn't realize it then,  but that feeling came almost directly from the book: "They have tried to take the life of my son!" Similarly, I'd forgotten that one of the most poignant quotes from the book also featured in my memory:

"One of the most terrible moments in a boy's life," Paul said, "is when he discovers his father and mother are human beings who share a love that he can never quite taste. It's a loss, an awakening to the fact that the world is there and here and we are in it alone..." 

And of course there's more. There's the subtle teaching about ecosystems and ecology, and the inspirational long term view of terraforming a hostile environment taking 300-500 years. Of course, it's taken us far less than 50 years to start turning our own planet into a hostile environment. There's the deliberate evocation of the Arabic desert nomads, the constant impingement into our consciousness all through the book about the preciousness of water, something that Californians are only starting to become aware of.

There's so much that makes this a great book. The rest of the series degenerated somewhat from this initial grand novel, and it was definitely well worth the re-read. Recommended.

Review: Tales from Earthsea

Despite loving The Wizard of Earthsea and most of the series, I bounced off Tehanu pretty hard, so wasn't going to consider it but then read the reviews (due to an Amazon sale) and realized Tales from Earthsea was a collection of short stories, so even if I bounced off one or two of them it would be OK.

The collection of short stories vary a lot, from the founding of Roke by Medra (which unfortunately never explains how it went from a collection of men and women to becoming a school where women are excluded, to a very quiet sequence about Ged chasing down an errant wizard. (Ged barely features in it) The final story, "Dragonfly" takes place after Tehanu but you don't really need to have read Tehanu to appreciate it. The story about how Ogion held back an earthquake is finally told. The book ends with the "series bible" so to speak that Le Guin used to do her world building. It's not pleasure reading, but is short.

LeGuin's prose is beautiful and flawless, which in itself makes the book a pleasure. Recommended.

Review: House Again Tea Infuser

In an effort to reduce caffeine (and also to break the palate monotony), I've occasionally drank tea. If you're going to use loose leaf teas, an infuser will make much less of a mess. I first tried the Finum Mesh Brewing Basket, but discovered that it was far too fragile: holes would develop in the mesh and then well, you'll have leaves in your mouth when you drink.

The House Again Tea Ball infuser turned out to be a much better choice, with a chain to wrap around the handle of the mug and a studier pocket that neither leaks nor breaks. It also comes with a handy saucer so you can take it out and reuse the tea leaves or just not have too strong/bitter a brew.

It doesn't seem to infuse any unwelcome flavors, which is all I can ask for it (other than the durability)..

Review: Panaracer GravelKing tires

Now that the local parks are open to Mountain Bikes again, we've been resuming our almost weekly cadence of mountain bike trips. My wife's Cheviot was not quite a mountain bike, having come with 33mm nifty swifty tires which aren't actually particularly swift.

I looked for wider tires and bought some Panaracer Gravel King tires. The product managers idiotically created several sizes and types of tires but gave them all the same name, so you have to be careful when you order tires what to get.

I started with the Gravel King SK+ 1.90 tires. These have knobbies and barely clear the Cheviot frame and brakes, but made such an awful noise that my wife asked for them to be removed and replaced with the nifty swifty because she'd rather put up with poor traction on the mountain bike trail than listen to those tires.

Upon switching to the 1.75 version of those tires, all those complaints disappeared, the tires cleared the frame better, and the rolling resistance was also much better. Get these, and not the knobby versions for an all-round bike.

Review: Voler Shift Terrain Pro Short

My Pearl Izumi Elite Shorts are now starting to be ragged (after 4 years and several bike tours), and the Quest shorts are also gone. They tend to die in ways that slowly become more and more uncomfortable. Pearl Izumi, of course, has since renamed the "Elite" the Pro and their stuff is now well over the budget I typically allocate for clothing ($170/pair!!), so I was at a loss.

The scuttlebutt seems to be that the Performance Brand Ultra shorts are actually pretty good (and Eric House says they refused to die on him). Then another internet source compared them with the Voler, and I skipped over to the Voler web-site and discovered that their Shift Milano Elan Pro short at $50 was quite a bit less than the Performance branded ones.

Upon first wear, the shorts felt a bit stiff, but less than 3 miles of pedaling on the triplet and they melded into my body. Subsequent washes and wear see no degradation of performance. Obviously, touring is out of the question for the foreseeable future, and we'll see how long they last, but I'm happy enough with them that as my older shorts become unbearable (or my sons start poking holes through them), I'll replace them with these.

I was so impressed that I spent an extra $5 each when they gave me a memorial day coupon and got the Shift Terrain Pro Short. These are so amazing that I'm glad I bought 2! I'm no longer dreading the day my Pearl Izumi Elites finally bite the dust.

Highly Recommended.

Review: Tides

Tides is appropriately written by a sailor. The book taught me several things that I didn't know, even though I was taught how to sail in the San Francisco Bay Area, where a tide table consultation is required before leaving the slip --- with currents exceeding 10 knots through the golden gate, a sailboat will not make it in or out of the gate except during slack tide.

Things I didn't know:

• A tide coming up or down a river is called a bore. The largest tidal bore in the world is in the Qiantang river in China. (The pictures are impressive)
• I'd long assumed that tides are small in places like the Mediterranean was because of restricted flow through a funnel. This is false. The reason tidal variation is small in certain places (e.g., the Carribean) is because tides actually vary around various centers in the oceans, and the further away you are from the center, the higher the amplitude.
• The earth itself (not just the ocean) is also affected by the same gravitational forces that creates the tides:  

If the moon can cause such a stir in the ocean, wouldn’t it also affect the solid earth? Do our bodies, made of 70 percent water, have a tide? Yes and no. The earth is as rigid as a steel ball, but it does distort under the gravitational influence of the sun and moon. High tide on the solid earth varies from half a foot to three feet and spreads over such a large distance—about ten thousand miles—that it’s not perceptible. For example, a high spring tide might raise the sidewalks and buildings of New York by a couple of inches. You could never detect this as you walk down Broadway, because everything rises and falls together over a six-hour period (unlike on the coast, where the ocean rises and falls relative to the beach). The tide’s daily squeezing and releasing of the earth has long been known to affect water wells too. A Wisconsin well, about eight hundred miles from the nearest ocean, has a two-inch tide. An inland well in France increases its flow from sixty to ninety gallons an hour during spring tides. (kindle loc 1883)

The book itself is written English-major journalism style. Sometimes I get very impatient with this style, because all sorts of "color" that might be interesting to an English major is uninteresting when I'm in a hurry to learn information. Similarly, I roll my eyes whenever he does something English-major like, for instance, visiting the British Library to examine Newton's manuscript for "Principia" and then writing things like: "The equations didn't mean anything to me." He does this several times in the book, which had me wondering why he was bothering to burn all those fossil fuels getting to those exotic destinations just to throw his hands up at a little bit of math.

All in all, the book was interesting in the concepts and for its visual imagery of some of the places he visited. It probably could have been 50 pages long if he'd just condensed all the technical information into concise, easy to understand form, but I guess that wouldn't get a publisher interested.

Review: Betrayal of Trust

I read Laurie Garrett's The Coming Plague in the 1990s but in the intervening years the USA always managed to avoid a major epidemic, so I assumed that her warnings had done the right thing. Then COVID19 happened and I realized we were just lucky. Which meant that her other book about public health might be similarly prophetic, so I checked out Betrayal of Trust (electronically) from the local library.

The book goes to great pains to separate public health from medical provision. The former is about prevention, and the latter is about treatment. She chronicles several major disasters that could have been mitigated (or even prevented) by a solid public health system: a bubonic plague outbreak in India,  the Ebola epidemic in Zaire, the rise of antibiotic resistant diseases (notably TB) in the former Soviet Union and the shift away from public health in the USA due to the perception that the big causes of mortality (cardiac problems and cancer) are non-contagious and therefore public health did not have to play a role.

Early on, Garrett points out that the big gains in life expectancy in the West were achieved long before antibiotics and other miracles:

Vital statistics data from England, Wales, and Sweden show that in 1700 the average male in those countries lived just twenty-seven to thirty years. By 1971 male life expectancy reached seventy-five years. More than half that improvement occurred before 1900; even the bulk of the twentieth-century increases in life expectancy were due to conditions that existed prior to 1936. In all, 86 percent of the increased life expectancy was due to decreases in infectious diseases.15 And the bulk of the decline in infectious disease deaths occurred prior to the age of antibiotics. In the United Kingdom, for example, tuberculosis deaths dropped from nearly 4,000 per million people to 500 per million between 1838 and 1949, when antibiotic treatment was introduced. That’s an 87 percent decline. Between 1949 and 1969 the TB death rate fell only another forty million cases to 460 cases per million, or 9 percent. (kindle loc 281)

During the Ebola epidemic, she notes that the requests for materials are very similar to what we're seeing during the COVID19 outbreak:

“Send respirator masks, latex gloves, protective gowns, disinfectant, hospital linens and plastic mattress covers, plastic aprons, basic cleaning supplies and cleansers, water pumps and filters, galoshes, tents …” It was not the high-tech equipment popularized in science fiction movies that would halt Ebola’s spread, Kiersteins knew. What Kikwit needed were the basics: soap, gear, and safe water. (pg 67)

She charts the rise of public health in New York City, which pioneered the initial systems that reduced the incidence of epidemic disease in the city despite the opposition of many to vaccines. But because circumstances were so dire, the public health department was authorized to use force. The trust in the public health system reached a high during the Polio epidemic:

In the fall of 1953 more than eighty thousand six-to-eight-year-old New York City schoolchildren rolled up their sleeves for shots of either Salk’s vaccine or a placebo. In 1954 and ‘55 tens of thousands of children nationwide enlisted as Polio Pioneers to serve as willing guinea pigs for the vaccine.185 And though every aspect of the Salk vaccine effort was mired in politics, ethical debates, and production and distribution snafus, there were never shortages of schoolchildren lining up for polio shots. The fear of polio was far greater than any parental concerns about the experimental nature of the vaccine.(pg. 315)

We can see the decline of public health occurred decades ago, during the shift in the late 1960s and 1970s:

Instead of emphasizing collective health and disease prevention, the path now would lead to further medicalization and individualization. Sadly, the data would later show that America was thereby exiting the period of her greatest health improvement since the Biggs era. Between 1968, when LBJ’s programs were in full swing, and 1975, when budget cuts had whittled such programs to the bone, the overall U.S. annual death rate had dropped 14 percent.323 Every health indicator had shown remarkable improvement. Cardiovascular deaths: down by 23 percent. Infant mortality: dropped 38 percent. Maternal mortality: plummeted an astounding 71 percent. That was the legacy of an aggressive war on poverty and expansion of health services for the poor. It occurred in a period that was denounced by the AMA and American Hospital Association as “regulated,” a code word meaning “very bad” or even “socialistic” in the New Right circles of rising political superstar California governor Ronald Reagan. (pg. 349)

The question is whether the USA still has the capacity to rebuild a robust public health system even after the obvious need for it. Garrett points out in a final chapter that a strong public health system is quite possibly the best protection against bioterrorism or genetically engineered bioweapon attacks. Unfortunately, she doesn't provide much hope as to whether such a system is politically feasible: the book was published in 2011, and there's no sign that in the intervening years much has been done.

Nevertheless, for a great discussion of the issues and lots of stuff I didn't know before, this is a great book. Recommended.

Review: Usagi Yojimbo - Yokai

Usagi Yojimbo - Yokai was an amazon giveaway. I haven't ever read any of the series before. The story revolves around Miyamoto Usagi, a dual-sword wielding samurai who apparently wanders about doing good deeds. He encounters a woman who has lost her daughter and agrees to help.

All is not what it seems, however, and soon he's embroiled in a supernatural battle and meets an old friend. The art is pretty, fully painted, but nothing that strikes me as being awesome. The story is kinda meh, but Boen was happy enough to have me read it to him. Typically, giveaways are intended to get you to look for more books by the same author/artist to read, but this left me cold.

Crush Vol 1

Crush Vol 1 was an Amazon giveaway. Lots have been written about how werewolves are a metaphor for a woman's menstrual period, so it's inevitable that some comic will take the metaphor and make it literal in a story.

The story revolves around Elizabeth, who turns into Crush whenever she bleeds, which includes that time of the month. Crush, is an amoral monster, who only barely resembles Elizabeth, but somehow she and her friends are convinced that the monster would never do something like kill. There's an unresolved long-running plot involving some other monster that's similar to crush and seeks her out, but it's never really explained in this volume, and doesn't seem special enough for me to want to pursue it.

The art is nothing special. It's clear that the artist wants to evoke Matt Wagner's Mage, but neither the story nor the art can quite live up to that!

Review: Scary Godmother

Scary Godmother was a kindle giveaway, and somehow Boen asked me to read it to him over several nights. Each story is self-contained, but it helps to read everything in order since  characters carry over from one story to the next. The art is cute. The text is simple and easy for kids to understand, and the plotline mostly targeted for little kids.

There's no explanation for any of the "scary" characters in the book, and how they live or come about. Your kid's expected to know all the myths (i.e., what's a vampire, etc). It's fun entertainment but I can probably count any number of other books that are worth your time.

Review: Plastics - A Toxic Love Story

Plastics is much less technical than I would have liked. It doesn't cover in great detail how plastics were invented, nor does it discuss, for instance, how the details of recycling plastics work. It does spend some time discussing the effects of plastics on your health, but again, without a lot of detail. What it does point out that I didn't know about, was the lack of regulation over chemicals and safety:

while twenty thousand chemicals have been introduced since 1976, the EPA has been able to require intensive reviews for only two hundred, and it has used its authority to restrict only five. The hurdles are so high, the agency could not even successfully ban asbestos, an undisputed carcinogen.

In Europe, the burden of proof is on safety rather than danger. European regulators “act on the principle of preventing harm before it happens, even in the face of scientific uncertainty.” Guided by that precautionary principle, Europeans began limiting DEHP and other phthalates while American regulators continued debating the risks. (The EU, for instance, barred the use of DEHP in children’s toys in 1999, nine years before the U.S. Congress passed similar legislation.) A new directive known as REACH (for Registration, Evaluation, and Authorization of Chemicals), adopted in 2007, requires testing of both newly introduced chemicals and those already in use, with the burden on manufacturers to demonstrate that they can be used safely. The agency charged with implementing REACH targeted DEHP as one of the first fifteen “substances of very high concern” to be regulated. (Pg. 106-107)

By the time we get to the Pacific Garbage patches (there are actually several garbage patches, distributed all over the world's oceans), we start to get a surprisingly balanced view of things:

The lighter, like every other piece of plastic debris they hauled up in their nets, was coated with a fine slime of microbes, including bacteria and phytoplankton—organisms that are essential to the health of the ocean. To his surprise, Karl found that the plants attached to such plastic objects are copious producers of oxygen, churning out even more from their polymer platforms than is normally produced in open ocean. The finding suggests that, at some level, the multitude of plastic debris may be “improving the efficiency of the ocean to harvest and scavenge nutrients and produce food and oxygen,” (Pg. 134)

The author (and the scientist quoted above) stopped short of saying that plastics in the ocean is a good thing, but as with many things it's not immediately obvious that plastics are an unmitigated evil. For instance, in comparison to paper bags, plastics actually have a lower carbon footprint: they're lighter and therefore the cost of shipping is much lower, and paper itself has issues:

Life-cycle analyses—studies that analyze a product’s cradle-to-grave environmental impact—have consistently found that, compared to paper bags, plastic bags take significantly less energy and water to produce, require less energy to transport, and emit half as many greenhouse gases in their production. Author Tom Robbins called the paper bag “the only thing civilized man has produced that does not seem out of place in nature,” but that’s true only if you ignore the tree-felling, chemical-pulping, intensive-bleaching, water-sucking industrial production that goes into making that natural, potato-skin feel of a brown paper bag. (Pg. 158)

The book also disabused me of the idea that landfills are about decomposition. They're not. They're truly about waste disposal, and the goal is for landfills not to decompose, as that would add to their carbon footprint. The author's passion clearly lies with the environmental activism movement, and it's clear from her coverage of it, where she points out how quickly lip service the plastics industry fades once the spotlight on them disappears, and why the structure of the industry is such that it's difficult to get consistent action from them without government regulation:

The only players with significant financial resources to invest in recycling are the resin producers, the major oil and chemical companies, he said. But their top priority is “to make and sell virgin plastics.” As long as oil and gas prices are reasonably stable, there’s no financial incentive for the Dows, DuPonts, and ExxonMobils to get into the recycling business. Nor do they want to alienate the beverage companies that buy their raw plastics to make bottles. Meanwhile, the companies that make plastic products—which might be expected to have an interest in using recycled materials—are too fragmented a constituency to put together an all-out campaign for more recycling, said Rappaport. “The guy making trash bags has nothing to do with the guy making bottles. He’s got nothing to do with the guy making toys. It’s so fractured that nobody can get enough critical mass and money together” to put into developing the recycling infrastructure. (pg. 192)

Her visit to China's recycling center was also enlightening. Once again, the recycling happens there easily because the workers are getting paid $200 a month, which explains why plastic recycling doesn't happen on the coasts of the US --- China can outbid any US-based recycling center, and shipping from the US to China is incredibly cheap because container ships would be going back to China empty otherwise.

I started out the book rather negative, but by the end of the book realized that I learned a lot more than I expected. Recommended.

 

 

Rejuvenating old phones

Boen clamored for a phone since his big brother had my old Moto X4, so I dug up Xiaoqin's old Moto X Pure, which had a battery that wouldn't last 30 minutes. I looked at the iFixit site and discovered that it had relatively little glue, which was probably all gone because the screen had already been replaced once, so orderer the ZURUN 3400mAh replacement on Amazon. The replacement was fairly easy, though like an idiot I had 3 screws left over after the procedure which would affect the longevity of the product.

Similarly, Xiaoqin dropped her Pixel 3aXL and broke the screen. That phone was less than a year old, so it was worth sending out the phone for repair despite Google asking for $150. During the COVID19 crisis my wife and I didn't even consider going into the walk-in shop, despite their "essential" status. That would have probably saved some money.

By far the easiest repair, however, was the the Moto Z Play Xiaoqin's mom was using (also a pass down). That one started having battery problems as well, and I dreaded having to open up the case. Then I realized that the Moto Z series of phones have a mod pack ability that we never used, and now was the time to use it. Ordering a Moto Z Battery mod from eBay, when the mod arrived I removed the phone from the protective case, slapped on the mod, and handed it back. Everyone was surprised by how quickly the repair was done, and I was surprised that it worked. Of course, compared to the $16 the Moto X Pure repair cost, the Moto Z Play mod cost $50, but not having any screws left over must count for something!

In normal times you could just go down to BestBuy and have their technicians replace a battery for $50. Though for waterproof phones there's a big question as to whether the phone would stay waterproof after the operation, usually by the time the phone requires that level of maintenance you're no longer as worried about damage, and the phone was fully depreciated anyway! The rest of society might believe in throwing away old stuff, but I firmly believe that it's better for the environment if we keep using what we have for as long as possible.

Neil Gaiman's Likely Stories

In this 80 page comic, Neil Gaiman re-unites with Mark Buckingham to provide adult-oriented stories. The framing story is a pub, with dark stories that perhaps no longer seem so dark in the light of the very real crisis brought about by a pub in Ischgl. I read through the book in one night, and the stories had a mildly haunting quality, but nothing that's particularly outstanding. It wasn't a waste of time, but I'm not going to put a "recommended" tag on it.

Review: The Paper Menagerie and Other Stories

Despite not liking his novels and his latest collection of short stories, I'd already had The Paper Menagerie on hold (in ebook form) at the library, and ended up reading it without high expectations. I have no regrets. Not only are most of the stories in this collection of higher quality, the entire collection as a whole explained to me why I found his other work uncompelling.

Ken Liu's best form is that of a short story. In a short story, he's capable of creating a coherent plot, sketching out characters that come to life, and even evoking emotions that elude him in long form. "The Literomancer", "Good Hunting", "The Paper Menagerie", "The Regular", "The Paper Menagerie", "All The Waves" are all award-worthy reads that are put together so well that I was astounded: not only are the subject topics germain (Liu kindly puts together a set of references in this collection for each story, so you can follow along his research), the characters are excellent and the cultural references uniquely his. Liu not only puts references to Chinese myths and history in his stories, but is also happy to explicate and work on Japanese history as well. "The Literomancer" in particular is happy to explain the intricacies of Chinese characters in a way that (to me at least) is not only familiar, but insightful.

The volume's longer form novellas demonstrate why his more recent work hasn't been appealing: his last story, admittedly inspired by one of Ted Chiang's stories, is bloated,  and overstays its welcome, with next to no character development, and despite the extensive bibliography, doesn't offer any new insight.

Nevertheless, even if you've read many of the stories in this volume, to read it in context and to explore his extensive makes revisiting them in this book well worth your time. Highly recommended.

Review: ANCOOL 5X Replacement Watchband for Fenix 5X

It was inevitable: while I'm nowhere near as hard on equipment as Bowen is, my Fenix 5X is still a daily wear device. 18 months after buying it and wearing it nearly continuously, I broke one of the eyelets on the wrist-band. And of course, it's the eyelet I use most often!

Garmin wants $50 for an OEM wrist-band, which is a bit rich. I've had mixed results from 3rd party vendors for things like cables, but I figured silicone is silicone, and it doesn't matter where it comes from. The ANCOOL band comes with a 12 month warranty, so I picked one up despite certain reviews claiming that it wasn't as comfortable as the OEM band.

Those reviews are wrong. The band is just as comfortable, and the easy-on-easy off nature of the band meant it was easy to swap back and forth. Recommended.

Review: The Making of a Manager

To a large extent, we are all products of our history and experiences. I spent my career at startups, so when I wrote Startup Engineering Management, I wrote a lot about the hiring process end to end. Julie Zhou, however, spent her entire career at Facebook, so for her, "working hard on recruiting" meant finding more time to interview.

The Making of a Manager is a good management book for people in precisely Julie Zhou's shoes: working at a hypergrowth environment after the growth has started, and with a ton of mentorship available and lots of money. The effect is that most of her advice revolves around the interpersonal sociology (what others would call politics):

if nothing my report said could convince me to change my mind, it’s insincere to act as if she had had a say. What if she responds, “Actually, I do have the time for it”? Or if she brings up a slew of other reasons why she’s the best candidate? I’d only be scrambling to give her another excuse, which would make her feel unheard. (Kindle loc 1333)

And her book also perfectly illustrates how low the expectations we have in industry for management positions:

at the point in which your team becomes four or five people, you should have a plan for how to scale back your individual contributor responsibilities so that you can be the best manager for your people. (Kindle loc 596)

Our standards for management are so low that we think that the management span of attention is at most 4-5. Compared to the great managers I know, who've successfully managed as many as a hundred people without intermediaries, most companies' approach to management guarantees that Zhou's perception is correct: if you do not give sufficient management training and set low expectations, that's precisely what you get.

Another interesting thing about Zhou's book is that Facebook was famously good about promoting from inside. So she assumes that's how everyone else operates and doesn't consider that other possibilities exist.

I don't want to put down this book. It's worth reading for the many practicalities of operating inside Facebook. It's incomplete, as opposed to a deeper understanding of how organizations should be constructed and operated, and doesn't provide those organizational principles. But if you're a Facebook employee newly promoted into management (and want to do the minimum so you can manage your 4-5 people) I bet this is an essential book and thereby is recommended.

Review: The Hidden Girl and Other Stories

The Hidden Girl and Other Stories is Ken Liu's giant collection of short stories. The stories run the gamut, from the title story (a fantasy set in the tradition of the Chinese martial arts stories), to a series of related short stories about a post-singularity, uploaded human digital world. Many stories explore contemporary technology trends though given the current state of the world, we're seeing how over-optimistic some of those projections are.

Liu cannot compared with his contemporary Ted Chiang --- some of stories (e.g., the ones about crypto currency) clearly do not age well and were probably written in a hurry. One of the stories in the book is actually an excerpt from one of his novels, which I thought was cheating, but obviously intended to sell his novel series, which was sort of lackluster.

But by and large, the stories were decent and made for a good break. Mildly recommended.

Review: The Spindle and the Sleeper

The Spindle and the Sleeper is another one of Neil Gaiman's young-adult/kids books in tandem with a talented illustrator. This is a mash-up of two well known fairy tales (the spoilers are in the title!) though unfortunately it only features 3 dwarves rather than seven.

The language isn't as lyrical as in say, Instructions or The Ocean at the End of the Lane, and the illustrations aren't nearly as beautiful as those in say, Stardust, which also had a better story. The best I could say of the book is that it's rather short (64 pages, and designed for fast reading especially since the many illustrations take up the full page).

Is this the first Neil Gaiman book where I couldn't put a recommended tag on it? yes it is. Good thing I paid $1 for it, but I really should have checked it out of the library, except that the library's closed because of COVID19.
