An N95 respirator with an exhalation valve still provides better source control than a surgical mask.

That from NIOSH. When pandemic masking started last year, I thought it was idiotic that I was asked not to wear my normal valved N95s, but was told that a single layer Buff gaiter was totally kosher. The CDC has justified my feelings:

As source control, findings from NIOSH research suggest that, even without covering the valve, N95 respirators with exhalation valves provide the same or better source control than surgical masks, procedure masks, cloth masks, or fabric coverings. In general, individuals wearing NIOSH-approved N95s with an exhalation valve should not be asked to use one without an exhalation valve or to cover it with a face covering or mask.

In 2021, equipping anything other than an N95/KF94/KN95, or other equivalent, in an attempt to protect oneself or others is just ritual.

Every Day Pliers

I carry Fix It Sticks for screwing and small Westcott scissors for snipping. Since learning about them last year on Jerking the Trigger, I’ve carried Knipex 87-00-100 Cobra Pliers for gripping. There are times when a classic multitool, like a Leatherman, is preferable, but I find this selection is more functional for most of my mobile tool needs.

I measure the baby Knipex pliers at an overall length of 103 millimeters and a mass of 60 grams. They are an excellent purchase.

Sustainable Infrastructure

Like the stone lined canals in Kyoto, the terraced rice fields of Java allowing for millennia of continuous rice growing, the sandstone aqueducts of Italy still able to transport water after two millennia, the ancient Greek amphitheater still in use for plays and concerts, the cobblestone streets of Copenhagen that haven’t been resurfaced in five hundred years, we need to go back to thinking about our infrastructure not in terms of five year plans and technical efficiency, but in long term sustainability. If a bridge cannot be built that will last a thousand years, why build it? Why not build one that will last, even if it will be a less efficient or more expensive in the short run?

Prepper dreams of edgeland wine

As a lifelong consumer of end of the world fantasies, I can appreciate the allure of the narrative this slick zine is selling. As a teen dungeon master, I had tremendous fun mapping out the post-apocalyptic ruins of my otherwise boring Midwestern hometown on huge sheets of hex paper. I couldn’t find many who wanted to visit them with me. Which makes sense, because these narratives are really the ultimate expressions of our alienation from each other, fantasies of solitary dominion and personal rewilding that reveal far more about the social structure of life under contemporary capitalism than they do about what its collapse would really be like.

The Rebirth of Industrial Mastery

A society’s progress depends on whether significant numbers of people are working toward goals that have never been achieved before and on whether they are able to mobilize resources toward them. People need to be able to act as founders, not just as members of existing institutions. The first step is to embrace modes of life that are conducive to vision and mastery. This cannot, for the most part, come from within existing institutions. They have neither the incentive nor the ability to create them.

In Afghanistan, Follow the White High-Tops and You’ll Find the Taliban

The popularity of the high-tops – which come in instantly recognizable white-and-blue boxes – is something rarely acknowledged aloud. But they are often inconspicuously displayed among the pairs of walking and running shoes, boots and sandals, a single sneaker sitting at the front of many vendor tables that line the bazaar’s dimly lit alleyways.

Unmasking China’s Maritime Militia

In a proposal published in 2014, Sansha City’s delegation to the Hainan Province People’s Congress admitted that the city was training fishermen to guard the islands and reefs within the city’s jurisdiction. The proposal further explained that “regardless of whether they are fishermen operating in distant seas or fishermen engaged in aquaculture or other activities, they can all become well-trained militiamen and receive corresponding subsidies.”

A Better Kanteen Lid

My favorite lid for standard mouth Klean Kanteen bottles is the Topoko Straw Lid B. It’s a simple flip-top straw lid. The only thing that makes it special is that the mouthpiece is covered when closed. It seems like a common sense concept, but so many sport lids have no provision for some sort of mud guard.

Other than that, there’s not much to say about the lid. It is completely leak-proof when closed. It is easy to operate one handed. It comes with two straws that can be cut to length. One is stiff and the other is bendy. I’ve found no functional difference between the two.

I have these lids installed on both the bottles I use on a daily basis – the 27 oz that I carry on my bike, and the 40 oz I use at home.

I did break one of the lids by accidentally dropping the bottle from about 4 feet onto concrete. It broke where the carry loop connects to the base. The lid still sealed and functioned properly. I only use the loop for pulling the bottle out of a cage or pouch, but I still purchased a replacement (and another spare) immediately.

The new lids I received were slightly different from the old ones. The bit that covers the mouthpiece is clear instead of black, and the edge of it is flush with the edge of the lid. On the old model, the black cover was a couple millimeters proud of the edge of the lid, which provided more purchase when grabbing the piece to flip it open. The older design seems superior, but I haven’t actually noticed a practical disadvantage with the new one. I can still easily and reliably flip the lid open, even with a gloved finger. (That is, however, with light gloves – the older design may have more of an advantage with heavy winter gloves.)

I’ve only used the lids on Klean Kanteen bottles. I use these bottles for water. I don’t know if there are any special considerations that would make the lids less than ideal for hot beverages.

I’ve used every iteration of Klean Kanteen’s Sport Cap since I bought my first bottle from them in 2005. They’ve all left something to be desired. The Topoko lid is a superior solution.

Rema Rotation

I previously outlined my patch kit, which is based around Rema patches and vulcanizing cement. Ensuring the health of the vulcanizing cement is key to the functionality of the kit. As with any liquid adhesive, it can dry out in an open tube. Or the tube may sprout a leak, causing the liquid to leak out and vanish. I have taskwarrior tell me to replace the cement in my patch kit every 3 months:

$ task add due:2020-01-01 wait:due-3weeks tag:bike recur:quarterly replace rema vulcanizing cement

The task is really just a queue for me to evaluate the condition of the kit. Because I do not get flats often, there’s a good chance that the cement tube in my kit will be unopened when I perform this evaluation. If the tube is sealed and appears in good condition, I’ll leave it in without replacing it. If it is open, I remove it from the kit and replace it with a new tube. The old cement goes into my toolbox at home. When I apply a patch at home, I’ll first try one these old, retired cement tubes.

Before marking the task as complete, I’ll also evaluate the patches in the kit, replenishing or replacing from my bulk supplies as necessary.

This process gives me extreme confidence that my patch kit will be functional when I need it.

X260 LCD Panel Replacement

I replaced the LCD panel in my Thinkpad X260 last month. The original panel had developed some scuffs from its years of service. They were never noticeable inside, but became mildly annoying when using the machine outdoors in direct sunlight. Since I’ve been working outdoors more often over the past year, I decided a replacement would be a worthwhile idea. The internet makes it look easy, as long as one purchases the right panel.

I was told that the X260 originally shipped with three different LCD panels, so my first stop was Lenovo’s parts lookup tool where I input my serial number and received in exchange a complete parts list. This told me that my original panel was an AUO B125HAN02.2 (FRU 00HN883).

A seller on eBay claimed to sell this exact model for $80. I placed an order, waited a couple weeks for shipping from Shenzhen, and opened the package to discover an IVO M125NWF4 R0. This wasn’t a complete surprise. I had heard that sellers often ship compatible products, rather than the exact product they sold. The panel looked almost identical, so I decided to try it.

Replacing the panel took about five minutes. The new panel does appear to function identically to the original – resolution, brightness, and colors all look the same to me. The only difference I can discern is that the new IVO panel looks a little less matte than the original AUO panel. (In the photo, the new panel is the one sitting to the side of the laptop. It still has the protective covering on it – evidenced by the red pull tab – which makes it look like it has Apple-level glossiness. I can happily report that the actual panel surface looks nothing like that.) If I shine a direct light on both panels, the edge of the light is a bit more diffuse on the AUO panel. I’ve noticed no practical difference due to this indoors. I’ve worked with the new panel outside a couple times now, and so far it seems to work great in that environment as well. And since it has no marks, it is definitely a net improvement over the current state of the original panel when outdoors.

According to Lenovo’s parts lookup tool, my backup X270 uses the exact same AUO panel as what was originally in the X260. So I now have 2 new LCD panels that are swappable between the two computers. This sort of redundancy makes me feel warm and fuzzy. I’ve also placed the old panel into storage as another backup. It remains perfectly usable outside of direct sunlight.

I first noticed the marks appearing on the old panel a couple years into its service life. It was clear these were caused by the LCD contacting the keyboard when the laptop was closed – more specifically, I assume that the problem is whatever grease or oil gets transferred to the keyboard from my fingers. To solve this I started covering the keyboard with a microfiber cloth before closing the laptop. Since I started doing this a few years ago, I have noticed no new marks appear on the panel. Now that I have a new panel, my expectation is that this technique will keep it in good condition for years to come.

There seems to be no shortage of sellers offering microfiber “keyboard covers”. I assume they’re mostly all interchangeable. The one I went with was Clean Screen Wizard for 12” Laptops. The actual dimensions of these cloths are about 10.5” by 6.75”. This is not large enough to cover the entire base of the laptop, but it is large enough to cover just the keyboard, which is all I wanted to accomplish. I was worried that if I bought a cloth large enough to cover the whole base (as they show the cloths doing in their product photos), I’d have to worry about lining the edges up just so before closing the laptop. The cloth intended for 12” laptops gives me enough wiggle room that I can just throw it on blindly.

I’ve since bought half a dozen of these same cloths and use them everywhere one uses microfiber cloths. The larger size, compared to typical eyeglass microfiber cloths, is convenient for cleaning optical and camera lenses.

Shoe Stats

Purchasing shoes online can be a bit of a shit show. Sizing varies widely across – and even within – brands. I tend to wear a 9.5 US or 42 EU in most footwear, but, without trying the shoe on in meatspace, an online purchase is always a gamble.

Some years ago, shortly after I first braved the world of footwear e-commerce, I started logging which size I wore in every shoe I purchased. This helped immensely because it allowed me to compare sizing when reading reviews. When researching a new shoe model, I look for reviews that compare it against some other model that I may have a log entry for. If I can’t find that, but I find a comparison to some other model, I may try to find reviews of that model which compare it to something I know. It is like playing Six Degrees of Kevin Bacon, but with shoes. (The more you play the game the more you win.) Eventually I try to form a statement like “if you wear a 9.5 US in Shoe X, you should buy a 10 US in Shoe Y”.

I do not log widths because I always wear whatever a brand’s “standard” width is. If I ever purchased something the brand considered to be “wide” or “narrow”, I would note that.

A couple years ago I began tracking weight in the same file as the sizes. Many older shoes have no weight logged, but I find it useful for entries where I do have the data. The weights are all “as worn” – meaning they are what I measured after replacing shoe laces (probably with Lawson Toughlaces) or insoles. So my weights might be a couple ounces different from how the shoes ship from the factory.

I recently reformatted my log into a nice TSV file so that I could look at it with VisiData. I’ve thrown the file into a git repository and published it on GitHub. If you wear the sort of shoes I wear, perhaps it will be helpful to you.
