six microns
Given that human chromosomes are on the order of 5 to 10 microns, I am thinking this export regulation doesn't apply to the hobby market. This is "use the machine in a clean room" level precision.
I wish there was a directory of WFH friendly companies somewhere. I have done the math and work from home saves me a ton of money and time. Plus, it seems like an enormously beneficial choice if you care about global climate change. Small companies that are willing to figure out how to maintain a good culture while working from home have a huge hiring advantage.
They usually choose a subset of customers to try UI changes on before rolling it out to everyone. This way they can estimate the general reaction before committing to it. They probably also have a dozen different layouts and text for this dialog that they are testing to see what makes people most likely to click yes. Its all just statistics to them.
The USGS has a much better article.

It does sound promising, but it looks like there is a fair amount of work to make it economically viable.
Thanks, I'm just thinking there should be a button somewhere on the community or user profile. I'm guessing we are going to get a lot more of this crap as time goes on.
Yeah, it could also just be a complete scam to get PayPal info or something. I'm just surprised there isn't a "report community" or "report user" button.
Feel free to report it if you can figure out how. I gave up looking for the right link on Amazon's page.
Gadgetbridge looks cool. I wish I had known about this before buying a Fitbit. I wonder how hard it would be to add support.
I guess the libraries and schools can make the decision and throw out things they don't find useful.
It probably also depends on the book. I have tons of outdated books on obscure topics within engineering, science, and computing. I doubt anyone would check out my 1995 book on the Vi text editor from a library. Although, if I'm lucky, perhaps it could be a collectors item some day. In reality, I'm probably going to just say "thank you for helping me so many years ago" and respectfully recycle the book.
Sometimes skins aren't enough to get up steeper sections. In this photo, I am climbing Snow Lion couloir. I have metal spikes on my ski boots called crampons that allow me to kick into the hardened spring snow. Also, there is a whippet ski pole in my right hand to stop myself if I slide down the mountain (not visible in the photo unfortunately). This is similar to an ice axe but combines with the ski pole for ease of use. For more information, you can read about the self-arrest mountaineering technique.
Snow stability: In Colorado and many other areas with contenental snow packs, this kind of slope presents a high risk of avalanche for most of the year. However, prediction of avalanche danger becomes more reliable in the spring when the snow melts and sticks together more (known as isothermalization). However, one must always be aware of other factors affecting the snow such as the temperature the night before, rain fall, time of day, and more.
As always, seek proper in-person training before attempting this kind of thing. This post is simply to satisfy curiosity and drive discussion.

The photo is of Mt. Neva from the top of Jasper peak. Great day with perfect snow.

Since things are pretty small right now, I am going to make a few posts introducing the sport of back country skiing. Remember the first step before going into the back country is to take an in person avalanche course (see the side bar). All the titles will start with "Back country skiing 101" so they can be found easily. As always, questions comments, or snide remarks are welcome!
One of the first questions people usually ask me about back country skiing is "How do you get up the mountain without a chair lift?".
There are a few different ways but the most common is called "skinning" as shown by this photo. The skis are pretty similar to resort skis (but often lighter). I use bindings that can be released at the heel and pivot near the toe letting the ski slide along as you walk like a cross country ski. There are skins attached to the bottom of the skis that allow the ski to grab the snow rather than sliding backwards. These skins also allow the ski to slide forward easily. The skins attach using a combination of removable glue and hooks on the front and back of the ski (the orange tails on the back of my ski are where these hooks mount).
The boots are also a little different from what you may find in a resort, the ankles can pivot freely until you lock them in place.
At the top of the hill, I remove the skins, lock the boots and heels in place and ski down.
I hope this is helpful for people, let me know what you think of this kind of post.

Hehe, I just grabbed the number off wolfram alpha's size comparison. Wouldn't surprise me if they are wrong, not sure where they scrape the data from. Anyway, my point stands, six microns is still stupidly small. Some dust or hair on the cutting edge and your precision is now out the window.
