Lawson Kline has been manufacturing high-quality outdoor equipment for about ten years.

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.

Holly Herndon composes music with machine learning.

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.

Monitoring Legible News

I was sent a link to Legible News last November by someone who had read my post on the now-defunct Breaking News. Legible News is a website that simply scrapes headlines from Wikipedia’s Current Events once per day and presents them in a legible format. This seems like a simple thing, but is far beyond the capabilities of most news organizations today.

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.

This script is used as the diff_tool in the urlwatch job definition.

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.

After I built this I discovered that somebody had created an RSS feed for Legible News using a service called Feed43.

Wired is running an editorial arguing that the 10,000-year clock is a waste of time (get it?).

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.

The article, however, reminded me of the idea of protopia, a neologism first coined by Kevin Kelly and lately championed – in a slightly different manner – by Monika Bielskyte.

Cloth masks are probably ineffective (at best) at preventing respiratory infection.

At worst, they may create a breeding ground for pathogens. A study of healthcare workers found that “moisture retention, reuse of cloth masks and poor filtration may result in increased risk of infection.” Stick with real N95 respirators, which may not look as hip, but do actually work.

New Year, New Drive

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.

humangear capCAP+

Ten year ago I discussed the humangear capCAP. My conclusion was: the capitalization of the brand and product name is stupid, the cap itself is a good upgrade to any wide mouth (63mm) bottle, but it will allow a few drops to leak out of a wide mouth Klean Kanteen.

Recently I was made aware of a new model: the humangear capCAP+. This one adds silicone gaskets to both parts of the lid, and boasts compatibility with a wider range of bottles. However, humangear explicitly states that this one remains incompatible with the wide mouth Klean Kanteen.

I like to live dangerously, so I bought the new model anyway. For a couple weeks now I’ve been using it on the same Klean Kanteen Wide 27oz bottle used in the previous review. Despite humangear’s warning, I have had nary a drop leak out from the cap. I have tried to make the lid leak by filling the bottle and storing it on its side, and by balancing the bottle upside down on the cap, but no water has escaped.

humangear capCap+

Other changes in the new model include redesigned grip cutouts, which I find to have made no practical change to the functionality of the cap, and a cap retention thing that I thought would be kind of a gimmick but is actually surprisingly useful. (I will point out that the full name of this feature is the “humangear capCAP+ CapKeeper”. Someone at this brand hates English.)

humangear capCap+

The new model weighs 56 grams (2 oz), which is 20 grams (0.7 oz) more than the original capCAP.

I’m happy with the capCAP+. If you have the original capCAP, and it doesn’t leak on your bottle of choice, it probably is not worth upgrading. If it does leak, consider trying the new one. If you have neither model, but you use a wide mouth bottle and rely on something like the Guyot Designs Splashguard, the capCAP+ may improve your life.
