Scientific American proposes a solution to the Fermi Paradox by using the European exploration of the South Pacific as an analog.
When the frequency of occurrence of settleable worlds in a galaxy is intermediate between high and very low, fascinating things can happen. Specifically, ordinary statistical fluctuations in the number and location of suitable worlds in patches of galactic space can create clusters of systems that are continually visited or resettled by wave after wave of interstellar explorers. Think of it as an archipelago, a group or chain of islands. The flip side to the existence of these clusters is that they are typically surrounded by large unsettled regions of space, places just too far and too sparsely distributed to bother setting out for.
He’s experimented with a wide range of products, and I’ve bought most of them. These days he’s known mostly for his cordage, which is unique and inovative, but cordage is not a topic I get overly excited about. I do get excited about stakes and Lawson’s aluminum Apex Stakes and Titanium Shepherd’s Hook Stakes are both probably the best on the planet. The titanium stakes are currently on sale, and he sent a description of how they are made to his newsletter today:
We cut, bend, and point each tent stake one at a time in our shop. I usually have to buy a very large quantity worth of Titanium, per diameter. And this is practically me begging them to sell to me. The mills I buy from require very large qty’s in order to sell to us, as they usually sell to big aerospace companies like Lockheed Martin, Boeing, United Technologies, etc, So it is very expensive to stock a product like our titanium stakes, as it is 100% an aerospace material.
The rods come to the shop in a wooden crate via motor freight. They are usually about 12 feet long. We first start off by using a rod parter to cut the stakes to length to get our blanks. If you have never seen one of these machines before they are very neat. It essentially breaks/shears the rod in a very clean and controlled manner. So they do not have to be saw cut. It’s like a sheet metal shear for round rods. Our rod parter will accurately cut rods from 1/16”-5/8”. There are two parting disc’s used to do all the of the work. They are made from hardened tool steel. So they are cutting like scissors so to speak, but the rod goes through a hole to keep the end round and to reduce the burr as much as possible. There is an adjustable stop on the machine that allows the first rod to be cut as the 10,000th one, with no real measurable difference between any of them. It is a highly precise machine.
Next, they are bent either one, two, or three at a time (depending on the rod diameter) on a custom made bender. This is a bender that I made myself over 10 years ago, and it has probably made 100,000+ tent stakes ever since. Last the stakes are pointed in another machine that I also custom-built. The stake is fixtured into a holder where it advances towards the cutting head and then puts a point on the end using a special end type mill.
There is no machine in the world that you could buy that could make a stake from start to finish, so I had to custom make two of the three machines to make these. This is the reason we are the only manufacturer in the USA making titanium tent stakes. (and probably because I am bad at bean counting…) I do know that it would be far more profitable for me to stock and sell Chinese stakes, but for me, the details matter. And I honestly love making custom machinery that can make products that not many other companies can. BUT as a result, this means I usually have way too many titanium tent stakes in stock as I have to make about a year’s supply at one time. Obviously, if I sold more stakes, then this wouldn’t be an issue, but since I don’t, this is the one product that I have a lot of my working capital tied up into.
I learned of her thanks to Bruce Sterling‘s mention in his 2020 State of the World, wherein he defines her music one of the few current examples of “genuine technical novelty”.
She used machine learning to train a program (referring to it as “AI” seems popular but I’ll refrain) that could reproduce human voices, and then used that software as a vocalist for PROTO. Neat.
Legible News provides no update notification mechanism. I addressed this by plugging it into my urlwatch system. Initially this presented two problems: the email notification included the HTML markup, which I didn’t care about, and it included both the old and new content of every changed line – effectively sending me the news from today and yesterday.
The first problem was easily solved by using the html2text filter provided by urlwatch. This strips out all markup, which is what I thought I wanted. I ran this for a bit before deciding that I did want the output to contain links. What I really wanted was some sort of html2markdown filter.
I also realized I did not just want to be sent new lines, but every line anytime there was a change. If the news yesterday included a section titled “Armed conflicts and attacks”, and the news today included a section with the same title, I wanted that in my output despite it not having changed.
I solved both of these problems using the diff_tool argument of urlwatch. This allows the user to pass in a special tool to replace the default use of diff to generate the notification output. The tool will be called with two arguments: the filename of the previously downloaded version of the URL and the filename of the current version. I wrote a simple script called html2markdown.sh which ignores the first argument and simply passes the second argument to Pandoc for formatting.
The result is the latest version of Legible News, nicely converted to Markdown, delivered to my inbox every day. The output would be even better if Legible News used semantic markup – specifically heading elements – but it is perfectly serviceable as is.
The thrust of the article seems to be that the world sucks today, and that building a monument to inspire long-term thinking is a waste of resources – “a pleasant distraction” – since everybody alive today will be dead before any good comes of it. Which, I don’t know, seems like it’s sort of the point.
There’s plenty to criticize about The Long Now – I swing by The Interval once a year or so, always hoping that it will have become an interesting place to spend time and always leaving disappointed – but I don’t think the idea of the clock is one of them. The rate of progress on the clock(s) is another matter.
My first solid state drive was a Samsung 850 Pro 1TB purchased in 2015. Originally I installed it in my T430s. The following year it migrated to my new X260, where it has served admirably ever since. It still seems healthy, as best as I can tell. Sometime ago I found a script for measuring the health of Samsung SSDs. It reports:
------------------------------ SSD Status: /dev/sda------------------------------ On time: 17,277 hr------------------------------ Data written: MB: 47,420,539.560 GB: 46,309.120 TB: 45.223------------------------------ Mean write rate: MB/hr: 2,744.720------------------------------ Drive health: 98 %------------------------------
The 1 terabyte of storage has begun to feel tight over the past couple of years. I’m not sure where it all goes, but I regularly only have about 100GB free, which is not much of a buffer. I’ve had my eye on a Samsung 860 Evo 2TB as a replacement. Last November my price monitoring tool notified me of a significant price drop for this new drive, so I snatched one up. This weekend I finally got around to installing it.
The health script reports that my new drive is, in fact, both new and healthy:
------------------------------ SSD Status: /dev/sda------------------------------ On time: 17 hr------------------------------ Data written: MB: 872,835.635 GB: 852.378 TB: .832------------------------------ Mean write rate: MB/hr: 51,343.272------------------------------ Drive health: 100 %------------------------------
When migrating to a new drive, the simple solution is to just copy the complete contents of the old drive. I usually do not take this approach. Instead I prefer to imagine that the old drive is lost, and use the migration as an exercise to ensure that my excessive backup strategies and OS provisioning system are both fully operational. Successfully rebuilding my laptop like this, with a minimum expenditure of time and effort – and no data loss – makes me feel good about my backup and recovery tooling.
