“Folding Beijing”

It is an extraordinary short story, one of the best things I’ve read all year, and it’s proof positive of how rapidly China is becoming a society supercharged with creativity.  I am pleased to see it received a Hugo Award for best novelette.

The author is Hao Jingfang and it’s on-line here.  Did you know she is a macroeconomics researcher at a quango in Beijing?  One key part of the plot and premise revolves around macroeconomic theory, here is an excerpt:

“Hard to say.” Lao Ge sipped the baijiu and let out a burp. “I suspect not. You have to understand why they went with manual processing in the first place. Back then, the situation here was similar to Europe at the end of the twentieth century. The economy was growing, but so was unemployment. Printing money didn’t solve the problem. The economy refused to obey the Phillips curve.”

He saw that Lao Dao looked completely lost, and laughed. “Never mind. You wouldn’t understand these things anyway.”

I cannot excerpt more without giving away spoilers.  Definitely recommended, and for the pointer I thank Eva.

Avoid Junk Guns with a Passion

Those new to the prepper and survivalist movement interested in obtaining firearms for self-defense or bug out protection are often drawn to the wrong guns. By that I mean the quality not always the type, brand or caliber. There are still a number of really poor made firearms in today’s marketplace and should be avoided at all costs, no pun intended. It is often the cost factor that leads many down the wrong pathway.

I was reminded of this first hand while working a recent gun show with my dealer friend. Gun shows are the opportunity to buy, sell and trade, often on both sides of the tables. Many guns come down the aisles by people wanting to sell or trade up. Quite often these guns are of low quality and of very little value though the original buyer may have paid too much for it to start with. Others carrying a family heirloom often are mistaken that their wares are worth hundreds or thousands of dollars. They usually are not.

A seller approached our table with a small chrome plated handgun, which is usually a red flag to start with. I looked at the gun and declined it. I knew the brand name as cheaply made, unreliable to function and inaccurate if it fired at all. The dealer looked it over and researched its used value on line with his laptop. He said the gun was worth about $65 at best, but that he was not interested in any gun of that low quality. The man was incensed, of course. He had paid $225 for a piece of junk. His bad. Which, of course, is probably why he wanted to sell or trade it to start with.

So, how does first time or a regular gun buyer tell the junk from quality? Most often it starts with the name brand but assuredly the price. In this day and age, if you buy any kind of a gun for say under $300 you are not getting much. The exception might be somebody you know at work or otherwise in a pinch to raise some money. Still know the brand and know the gun. Then inspect the condition and standard evidence of use or abuse.

If you stick with a well-known handgun brand such as Smith & Wesson, Colt, Ruger, Browning, SIG, Beretta, Kimber and such you will buy quality. Same for long guns from names like Remington, Ruger, Winchester, Marlin, and many others. There are over 1000 brand names of ARs now, so pick established known makers. Beware of ARs that may be homemade by parts assembly in garage workshops. Seek out a good gun value reference book to learn more or perform an Internet search.

Next comes the inspection of the specific gun if it is used. Another good reason to buy NIB, or new-in-the-box guns. Then you just have to research the model, features, caliber, and functioning characteristics such as striker fired, hammer fired, single stack or double, etc. to match your needs, wants, desires, and expectations. You can better learn this at a shooting range or shooting course, which is highly preferred and recommended anyway.

Used guns can be a good value at a good purchase price, or you can get screwed. Obviously if you were shopping for a used car, you likely would not pick one with a missing bumper, or the back fender crushed in, seats ripped, or three different types of wheels or hubcaps. Today you would want a Carfax report to review its history. Get my point?

Look at used guns in this same light, because there is no “Gunfax” and dealers after all are trying to sell what they have regardless. Buyer beware is the watchword.

If the firearm is overtly worn, scratched up, stock cracked, sights missing or bent, bluing or other finish highly worn or just looks “rough” then it was probably abused and not well maintained. Are the weapon’s screws intact with screw heads not turned out? Does it look like a shade tree mechanic had been tinkering on it? If so, avoid the potential trouble and move on.

Is the gun clean? Why dealers put a dirty used gun on their shelves or tables is beyond me. If a revolver, check the cylinder for burned powder and a lead build up. Same for the barrel using a bore light, which is simply a special flashlight or clear tube to focus a beam down the barrel. Inspect the barrel for signs of wear. Lands and grooves should be well defined and sharp, no chinks or chucks, scratches or dark spots. Inspect the muzzle crown for damage.

If a semi-auto pistol, check the chamber and barrel for dirt, grime and lead. Make sure the magazine is original and locks up. Double check the safety mechanisms on all guns. Truth is if a gun looks worn or overly used, then it probably is, but it could still be mechanically sound and safe. Just be careful.

On rifles and shotguns, check the bolt heads, chambers, and loading mechanisms as well as the safety. Cycle the bolt and then bounce the gun on the floor with the safety “ON” especially with shotguns. If the firing pin releases at this test, pass on it. Inspect scope mount holes on rifles to see if the original factory screws are in place. Has there been a scope mounted but is now missing? Inspect the barrel as suggested above. Look for heavy copper or leading fowling in the barrel which means the owner never cleaned it. Again such a gun could be recovered, but be mindful.

The main point here is if you are just starting out in the buying of a gun(s), then use caution with used guns and for new ones, just buy a well-known and recognized brand and model. What you don’t need is a gun that does not function well or breaks down with little use.

Marvel just released 5 hours of superhero holiday fireplace videos

If there’s one thing I consistently love and can be trusted to both enjoy free or even pay money for, it’s fireplace videos. Sometimes called yule log videos, too, these are those things you see on Netflix, in the Apple TV App Store and on YouTube that just show a fireplace for a long period of time, often looping a clip and sometimes including music or sound effects. They’re arguably the best televisual content currently available, and Marvel wants in on that red-hot market.

The Disney-owned superhero brand behind favorites including The Avengers, Iron Man and Mrs. Marvel released five separate fireplace videos in 4K resolution on its YouTube channel, each around an hour in lengthy. The Coca-Cola-sponsored clips also include an “up close” variant in 1080p HD, since the 4K originals are way zoomed out to give you a sense of the surrounding environment, each of which ‘belongs’ to a specific Marvel superhero or super team.

There are videos for Guardians of the Galaxy, Iron Man, Thor, Ms. Marvel and Captain America, and each contains some set dressing unique to the character, as well as background audio that will make you feel like you’re right there next to these heroes enjoying their hearth.

Some of the videos also appear to contain brief Easter Eggs, but not that are particularly revelatory about plot points or aching like that, unfortunately. There’s a dancing baby Groot in the Guardians one that is shamelessly adorable, though, if you’re looking for that sweet, sweet sap.

All of the fireplace videos are included in the YouTube playlist embedded above, so go ahead dim the lights, mull some wine and enjoy the vibes.

Designer’s Resource: Here’s How You Can Search a Massive, International Design Patent Database for Free

Have you ever wanted to search for existing or expired design patents not only in your own country, but in the countries where you’d like to sell your designs? A website called DesignView has wrangled together the design patent databases of 45 countries, plus the ARIPO (African Regional Intellectual Property Organization), EUIPO (European Union Intellectual Property Office) and WIPO (World Intellectual Property Organization), and lets you search all of them at once with a single search box.

Even better, the service is completely free, and they claim the databases they have access to are updated daily.

Just out of curiosity, I typed in "waffle irons" and got 97 results from a host of countries. I then discovered that the 2003 patent on Philippe Starck’s waffle iron design has expired, meaning this is a prime time for me to swoop in and produce a too-close-for-comfort competing product.

Door Monkey

My wife and I have been using Door Monkeys for 2+ years to keep our (now 3 year old) child and cats in or out of various parts of our apartment. At our peak, we had 6 of them active and they travel with us when we visit the grandparents. It is a temporary, instant door “lock” that can be left in-place and is very easy for an adult to use or remove. They are great because they can positioned at any height and even a toddler can learn to use them. They hold the door open about 1” and resist moderate pulling.

They are a parenting life-saver — from what I can tell, keeping a toddler on-task is dependent on cutting their options. I get a little hit of dopamine every time I latch a door and KNOW I’m not going to be beat by a mad dash.

If your a systems-thinking nerd: this tool trivially cuts the “life with a toddler” problem space. The blurb on Amazon says: fits standard 1-3/8″ thick interior doors, requires standard rectangular door stop moulding (see photos), rounded or beveled door stop moulding requires the Optional Catch (sold separately)”

Issues: They break – a guest didn’t realize we had Door Monkey on and pulled hard enough to break it. They’ll take a 3’ drop okay, but can get messed up if dropped from higher or thrown. On a bigger drop, the internal spring has popped off. I was not able to get it back on, but used a strong, short rubber-band on the outside to take its place. Those are my favorite, because they grip the door really tight. They absolutely chip paint and leave minor dents in molding. For us it’s worth it for the certainty they give. Maintenance: Silicone spray lubricant few months prevents them from sticking.
