Mini Review: Skilhunt H02R Head Mounted Flashlight, For Cycling after Dark

This xkcd comic came out today with perfect timing:

Last month I was contacted by GearBest and asked whether I'd like to do a review of a product from their cycling gear or LED lights categories; I'd get to keep the product in exchange for an unbiased review. Probably they'd seen my headphone review done under similar circumstances. I get this kind of message every so often and don't usually accept, but a bicycle light piqued my interest.

I chose to try out a small, $50 head-mounted light that I thought might be useful for nighttime riding:

The flashlight easily [...]

A Heatmap of All My Cycling In and Around Kyoto

I built a "heatmap" showing all the places I've ridden my bicycle since getting into cycling earlier this year. I thought it might be interesting for visitors researching rides they might want to try.

It's here: "Heatmap of Jeffrey's Cycling in Kyoto".

At the moment it includes data on 76 rides, with areas of yellow and red being more-often visited roads.

Clicking anywhere I've ridden brings up a list of rides that passed the area...

In the example above, I'd ridden the clicked-on road three times. Clicking then on the most-recent ride name highlights the whole ride on the map, [...]

Photoshop Calendar Templates for 2016 (through 2020)

FYI, I've just updated the page for my Photoshop calendar-template-building script to include pre-built PSDs for 2016 (and 2017, 2018, 2019, and 2020), in case you can't run the script but have Photoshop and want to make some custom calendars.

Mini Review: Axgio Bluetooth Wireless Sports Headphones

A month and a half ago I got an email out of the blue asking whether I'd like to have a free pair of wireless bluetooth headphones in exchange for a review on my blog. Well gee, sure, why not?! It's cheap advertising for them if I like them, but they risk bad PR if I don't.

In the past I'd tried small wireless headphones from Avantree, ECSEM, and Mpow before finding a pair I liked, "BlueAnt Pump". I was happy with those, but figured it wouldn't hurt to give another pair a try.

So, I was sent a pair [...]

Delight and Dismay at the Apple Store

The other day I got to witness the most amazing experience of watching a lady in her 70s touch an iPad for the first time, and right before my eyes the delight and sparkle on her face transformed her into a young girl again. It was magical.

Yet this experience at an Apple Store in Ohio was marred by some shockingly un-Apple bumps in the road.

I'm in America visiting my folks, and took the opportunity of being here to help Ann, a family friend in her 70s, buy her first computer. Until now her most technically-advanced electronics were a [...]

Bike-Fitting Session at Vincent Flanagan’s PedalForth Fitting in Kyoto

If you ride a bicycle for long distances, as I have been wont to do lately, you want to feel comfortable on the bike and ride with a posture that doesn't lead to injury. If something is so obviously uncomfortable that you notice it right away then of course you correct it or at least try something else, but it's the subtle poor riding posture that can insidiously lead to long-term injury.

I often get numbness in my fingers after a long ride, and my own brother had to give up cycling after a long ride left him with chronic [...]

Looking for Modern Bifocal Sunglasses….

I'm surprised that no one seems to make bifocal sunglasses for use in reading a phone or tablet screen. I'd think that this would be a popular product among the technically-savvy over-40 crowd.

I've been trying this pair of bifocal sunglasses for a few weeks, and while they may be great to read a book with, they're literally worse than nothing when it comes to reading my iPhone screen because the reading-glasses part is also shaded. The darkness of the screen makes it less readable than the poorness of my eyesight.

My ideal sunglasses would be clear and unpolarized for [...]

More GPS Cycling Tests: Things are Pretty Bad and There’s Little Hope

I made my second cycling run up Mt. Otowa (音羽山) on Wednesday, the first having been two days prior in the gloomy late afternoon just before a typhoon came through. Wednesday's was the first afternoon after the mild typhoon passed, so I expected the air to be really clear (like this and this), so I lugged my Sigma "Bigma" 50mm~500mm zoom all the way up there, along with the 2×TC to give me a 1,000mm lens.

It was so not worth it... it was the most hazy I'd seen it in ages.

The only things that were sort of clearly [...]

The Voodoo of Elevation Gain and Strava (and How I Get Around It)

In the screenshot of Google Earth above, you can see the route that I rode my bicycle last Wednesday... the little bit of green coming in from the right is a downhill section of road, followed by the long red uphill section through the tiered rice paddies of the village, then up the mountain on an old road no longer open to traffic.

I'd ridden 55km (34mi) to get to that point, and would end up riding 72km (44mi) farther before I got home, but ever since my first "real" ride in February, I've not been so interested in how [...]

Thoughts on the Venus/Laowa 60mm f/2.8 Super-Macro Lens

After seeing it mentioned on PetaPixel earlier this month, I ordered a Venus (LAOWA) 60mm f/2.8 Ultra-Macro lens. For less than $400 I didn't expect much, but it was worth a try.

(It seems they're changing their name from "Venus" to "Laowa". The Chinese characters for "Laowa" seem to be 「老蛙」, which means "Aged Frog", at least in Japanese.)

This is not a "review"... just some observations that I haven't seen others make yet, and some illustrative photos. In addition to the review on PetaPixel, other reviews I've seen include this and this.

For the TL;DR crowd, here in short [...]

Photo-Development Challenge: Inspire Me and Others With Your Artistic Interpretation

A week ago I posed about a fantastic video of an experienced photographer giving a quick once-over to photographs submitted by strangers. The change from unprocessed original to processed result was often striking and of interest on its own, but the true value of the video was the running dialog of the what/why/how of his editing decisions. No right or wrong... just inspiration and ideas.

With that in mind, I think it could be quite interesting to see how different people interpret the same photo, so I'd like to offer a few unprocessed raw files from my own photo archives, [...]

Facebook Engineering Opens a Satellite Office in Kyoto (For a Few Hours)

Facebook engineer Ryan Mack and his wife Nadia and their blissfully-sleeping two-year-old took time from their 10-year-anniversary Japan trip to join me for dinner at Uroko (鱗) in downtown Kyoto the other night.

Ryan has sometimes provided help or insight on navigating the complexities of Facebook's third-party app API, which I must use for my Export-to-Facebook plugin for Adobe Lightroom, so I was happy to finally meet him in person. Meeting Nadia was a wonderful bonus, though I didn't really get to meet his son, who slept the whole time we were together. (Jetlag sometimes giveth, I guess.)

It's just [...]

New Lightroom Plugin: People Support

I've finally released a new plugin for Adobe Lightroom that I've been working on for some time, my "People Support" plugin. Once configured, it can tell you the age of people in a photo, and include that data in exports.

It's consumed me for weeks. The idea of calculating and displaying a person's age seems quite straightforward and simple, doesn't it? It's not. Date calculations are surprisingly fraught with complexity, and presentation all the more so when you take into account dealing with all the languages that Lightroom can work in.

English is simple in that we use the same [...]

The Art and Science (and Complex Frustrations) of Creating my Wigglegrams

This post is about the art and technology of my 3D wigglegrams, but first a bit of context about the location seen above.

This wigglegram was taken during my first visit to Kyoto's Shugakuin Imperial Villa (修学院離宮) two years ago, a photographically-fruitful outing first posted about here, and most recently revisited a month ago here.

During the tour of the grounds, at one point you descend stone steps set in the side of a mountain....

There's a waterfall and a small stream... it's all quite picturesque.

As I described on that first post about the outing, the tour moves along [...]

Fixing Lightroom Problems Caused by the POODLE Security Vulnerability

A security weakness dubbed "POODLE" has recently been discovered in how internet-connected applications make secure connections, and this is having an increasingly-detrimental impact on Lightroom. Thankfully, it's easy enough to fix for most folks, and this post tells you how.

POODLE manifests itself in that certain kinds of secure connections are no longer quite as secure as they're supposed to be, so until you fix this for your Internet-connected applications, your data may be at risk. But the secondary problem is that, until fixed on your system, your Internet-connected applications like Lightroom may experience seemingly random network errors as more [...]

Populating The Drive Bays of a Synology NAS Unit: Lessons Learned

(Recent posts have been filled with fall colors, so for some balance, I'm dipping into my cherry-blossom archives)

For the last few years I've had a Synology DS1511+ NAS unit... an always-on "network drive" that sits in a closet at home that I can access on my home network from all my computers at home. I use it for local Time Machine backup, as well as a local CrashPlan repository for various backups. (I also use CrashPlan to keep backups offsite.)

The Synology unit has five drive bays, which I initially populated with 3TB Seagate Barracuda drives.

That was a [...]

My Best (and Last) Score in the 2048 Game: 76,936

This won't mean a thing if you don't know this game, but if you do, I hope your jaw is suitably on the floor at that score.

When I still had the cold that I recently got over, I would sometimes pass the time playing the simple game "2048". I played on my phone, but anyone can play for free at the creator's website. It's fun and addictive.

During this sick time a game would last a few minutes, and I could get a score of about 2,000. Anthony and I had a running competition, and at first he could [...]

Sigh, Lost All Email For the Last Day

I've used Emacs as my primary email client since about 1982, and for the first time in those 30+ years it inexplicably deleted my entire queue of unread mail (about 1,400 messages) when I tried to load the last day's worth of new mail this morning. Doh!

The thought of losing 1,400 messages awaiting my attention was both frightening and liberating. Sadly, I keep good automatic backups (in this case with Crashplan), so I was able to recover my mail queue as it stood a few hours ago.

As I mentioned yesterday, I've not been too attentive to email lately [...]

Lightroom Catalog Maintenance: Clearing Out Edit History For Potential Performance Gains

This post is about trimming down the file size of an Adobe Lightroom catalog. In keeping with the off-season them of my previous post (which was filled with fall-foliage photos), this post is sprinkled with a few photos from Kyoto springs past, chosen more for their mentally-calming effect than for photographic quality, which they generally lack. (Sorry)

In a nutshell, if you have a large Lightroom catalog, and if you don't need the detailed editing history for your photos, you might be able to significantly reduce the size of your Lightroom catalog by flushing that edit-history data, which might generally [...]

Mini Rant: Disappointed in Netflix Video Streaming

I've been subscribing to Netflix's video-streaming service for a month or so. For $9 bucks a month it's a great deal and I recommend it, but that being said, it's also a big disappointment over what I expected.

YouTube has defined what's expected in video streaming, and the Netflix experience is so much worse. One problem is that the video quality is usually pretty bad -- blocky and pixelated -- even though I have a very fast connection (even via the VPN that I require to access Netflix from Japan). I can watch super-HD 1080p videos on YouTube without problem, [...]
