In the 24th Tank Chat, David Fletcher looks at the rather unusual Vickers A1E1 Independent. The Independent originated in 1922 with a War Office specification for a heavy tank. Ultimately it proved to be a failed project was abandoned in 1935, by which time it had cost more than £150,000, and sent to Bovington. It is the only tank of its kind in existence.

In the final episode of the webseries, we tackle how markets make and break stuff.

—–

In free and open markets people are able to make new technologies and business models, which displace older, established ones. That process of starting new companies and jobs destroys some professions while creating others.

It’s entirely understandable that people who lose their jobs want to keep them. But industries like manufacturing, coal mining, and mall retailers aren’t dying out because of competition from China, they’re being outmoded by automation, cheaper fuel sources, and online sales.

Despite the uncertainty that markets bring, they also create new jobs and entirely new professions. There aren’t gangs of unemployed lamplighters roaming the land; their descendants became Uber drivers, social media coordinators, and webseries producers.

In the end, it’s better for everyone to look at the world as it is and to move forward than to try and halt progress through the force of law.

Mostly Weekly is hosted by Andrew Heaton with headwriter Sarah Rose Siskind.

Playboy‘s extortion attempt against Boing Boing dismissed

Filed under: Law, Liberty, Media, Technology, USA — Tags: , , , — Nicholas @ 05:00

Back in January, I linked to the bizarre story of Playboy attempting to sue Boing Boing for the terrible crime of … linking. On the web. I’m not making this up. Thankfully, common sense finally did triumph as reported on Monday:

In January, we let you know that Playboy had sued us. On Valentine’s Day, a court tossed their ridiculous complaint out, skeptical that Playboy could even amend it. Playboy didn’t bother to try.

We are grateful this is over. We are grateful for the wonderful work of the EFF, Durie Tangri, and Blurry Edge, our brilliant attorneys who stood up to Playboy‘s misguided and imaginary claims. We are glad the court quickly saw right through them.

Playboy damaged our business. This lawsuit cost our small team of journalists, artists and creators time and money that would otherwise have been focused on Boing Boing‘s continued mission to share wonderful things.

Real estate reality may finally be changing minds in Silicon Valley

I’ve never lived in Silicon Valley, and my one vist there was over 25 years ago — but even then, I thought the real estate market was far higher than it should have been. The sale of a tiny house in Sunnyvale (for $2 million or $2,358 per square foot) is symbolic of real estate values all around the area, as the stories get told of new employees living in their cars because even on six-figure salaries, they can’t afford to buy or even rent near where they work.

Cannon loading in the eighteenth century

In Fort Rinella. Kalkara, Malta, every day, they put on a show of loading and firing cannons, and members of the public are invited (for a fee) to fire them off.

The cannon shown are eighteenth century barrels mounted on more modern carriages. The uniforms worn by the crew do not match those worn by eighteenth century artillerymen, but these same men were just minutes before performing a Victorian infantry drill, and are still dressed for that.

The loading process shown here is not complete, because it lacks the vital stage of ramming in the ball and wadding. The carriages each have a stopper behind them, securely fixed down into the ground, so that they do not recoil backwards dangerously, and since no heavy ball is being fired, there is not nearly so much recoil as there would be in a battle.

Why Is The Porsche 911 Rear-Engine?

Why Does The Porsche 911 Carrera Put The Engine In The Back?

When you’re sitting at the drawing board, one of the most critical decisions you’ll make in designing a vehicle is where you place the engine. The engine’s placement will have a huge impact on passenger space, practicality, acceleration, braking, weight distribution, and overall driving dynamics.

Porsche decided to put the 911’s engine in the back, behind the rear axle, way back in the day when the 911 was first designed. Since then, that engine has remained there, and while some might say it’s out of stubbornness, there are legitimately wonderful reasons for having a rear-engine car. In this video, we’ll discuss five different scenarios, and how a rear engine makes a lot of sense for each.

The notion of “uploading” your consciousness

Filed under: Health, Science, Technology — Tags: , , , , , — Nicholas @ 03:00

Skeptic author Michael Shermer pours cold water on the dreams and hopes of Transhumanists, Cryonicists, Extropians, and Technological Singularity proponents everywhere:

It’s a myth that people live twice as long today as in centuries past. People lived into their 80s and 90s historically, just not very many of them. What modern science, technology, medicine, and public health have done is enable more of us to reach the upper ceiling of our maximum lifespan, but no one will live beyond ~120 years unless there are major breakthroughs.

We are nowhere near the genetic and cellular breakthroughs needed to break through the upper ceiling, although it is noteworthy that companies like Google’s Calico and individuals like Abrey deGrey are working on the problem of ageing, which they treat as an engineering problem. Good. But instead of aiming for 200, 500, or 1000 years, try to solve very specific problems like cancer, Alzheimer’s and other debilitating diseases.

Transhumanists, Cryonicists, Extropianists, and Singularity proponents are pro-science and technology and I support their efforts but extending life through technologies like mind-uploading not only cannot be accomplished anytime soon (centuries at the earliest), it can’t even do what it’s proponents claim: a copy of your connectome (the analogue to your genome that represents all of your memories) is just that—a copy. It is not you. This leads me to a discussion of…

The nature of the self or soul. The connectome (the scientific version of the soul) consists of all of your statically-stored memories. First, there is no fixed set of memories that represents “me” or the self, as those memories are always changing. If I were copied today, at age 63, my memories of when I was, say, 30, are not the same as they were when I was 50 or 40 or even 30 as those memories were fresh in my mind. And, you are not just your memories (your MEMself). You are also your point-of-view self (POVself), the you looking out through your eyes at the world. There is a continuity from one day to the next despite consciousness being interrupted by sleep (or general anaesthesia), but if we were to copy your connectome now through a sophisticated fMRI machine and upload it into a computer and turn it on, your POVself would not suddenly jump from your brain into the computer. It would just be a copy of you. Religions have the same problem. Your MEMself and POVself would still be dead and so a “soul” in heaven would only be a copy, not you.

Whether or not there is an afterlife, we live in this life. Therefore what we do here and now matters whether or not there is a hereafter. How can we live a meaningful and purposeful life? That’s my final chapter, ending with a perspective that our influence continues on indefinitely into the future no matter how long we live, and our species is immortal in the sense that our genes continue indefinitely into the future, making it all the more likely our species will not go extinct once we colonize the moon and Mars so that we become a multi-planetary species.

A few jotted notes on woodworking plane companies

Filed under: Britain, Business, History, Technology, USA, Woodworking — Tags: , , , , — Nicholas @ 06:00

I’ve been dabbling more in the woodworking hand tool market recently, and found myself getting confused about the various manufacturers and their products. Mostly to try to sort out the history for myself, I started taking notes as I trawled from website to forum to auction site, looking for answers. In a very abbreviated and assuredly incomplete and inaccurate thumbnail sketch, here’s how I think the woodworking hand tool market has changed over the last hundred and fifty years or so:

  • Until the mid-19th century, most woodworkers made their own tools whenever they could, as the ability of manufacturers to produce economical, dependable tools was limited, and woodworkers (like other skilled craftsman of the early industrial era) were capable of producing most of the necessary tools with only minimal outlay to other trades.
  • By the mid-19th century, innovators and inventors were prolific in their proposed solutions to all kinds of problems (some real and many probably imaginary). Among those many, many febrile innovators was a gentleman named Leonard Bailey. Bailey managed to almost single-handedly revolutionize the woodworking market by coming up with a line of hand planes that could out-compete most of the hand-made competitors while taking advantage of the economies of scale offered by mass production. It became more economical for a woodworker to buy a ready-made tool rather than take time away from productive work to fabricate it for himself.
  • The Stanley Works of Massachusetts bought Bailey’s company — probably more for the value of Leonard’s patents than for the company’s sake itself — and parlayed that patent protection into becoming the acknowledged standard for woodworking planes.
  • Even after the Bailey patents expired, other manufacturers paid backhanded tribute to Bailey by straight-out cloning his designs with very minor changes and putting their own functional copies on sale in direct competition with the original Stanley products … often even using the same or barely concealed names/numbers for their clones (for example, the British company Record generally just prepended a zero in front of the “standard” Stanley model numbers, where a #4 plane from Stanley was a #04 from Record).
  • In the British market following the financial crisis of 1929, the government’s imposition of tariffs against inter alia American hand tool manufacturers encouraged many British companies to introduce Stanley clones for both domestic and Imperial markets. To their credit, not all of the opportunistic entrants went for the low-hanging fruit, and some of the British clones were at least as good and in some cases superior to the original products.
  • After the Second World War, the market for woodworking hand tools in North America began a rapid decline, although it remained strong enough in Britain to keep many of the clone manufacturers going for another 20 years or so. In response to the softening market, Stanley began to cheapen their manufacturing processes and the product quality began a precipitous decline.
  • By the early 1970s, Stanley had almost completely given up the hand tool market in woodworking, and their products were a sad mockery of what they’d been producing just a decade before, but North American woodworkers were inundated with innovative power tools from, among others, Black & Decker and the Sears Craftsman line that promised better/faster/more productive output from amateur woodworking shops than could be done with hand tools alone. That, coupled with the decreased emphasis on “shop” subjects in North American high school curricula meant that youngsters didn’t automatically become familiar with the use of hand tools unless they were already interested and had access to a workshop to indulge that interest.
  • The same process of shrinking market requiring “rationalization” and “economization” hit the British manufacturers fifteen to twenty years after Stanley and their surviving American competitors, and the order of the day was ever-shrinking profit margins, smaller markets, and mergers/bankruptcies/take-overs among the tool manufacturers.
  • After the financial bloodbath of the 70s through the 90s, it became clear that there was still a small-but-affluent market for quality woodworking hand tools, and a few new entrants made their mark by first copying the best designs of the past and then, hesitatingly, innovating with modern technology beyond what was possible a generation or two earlier.

Here are some notes I jotted down about a few of the key woodworking hand tool manufacturers and their respective rise and decline, based on a very cursory survey of what information is available online at the moment:

STANLEY (USA, UK, CANADA and AUSTRALIA)

A vintage Stanley No. 4 smoothing plane from a recent eBay listing. Even though this is the single most common woodworking plane ever, the example I own is a late-70s piece of crap, so I went looking for a more representative image.

The Stanley Works was founded in 1843 by Frederick Stanley in New Britain, Connecticut.

In 1857, the Stanley Rule & Level Company was founded by Frederick Stanley’s cousin Henry. I imagine most people of the time assumed there was only the single Stanley company, as they produced products in related-but-not-competitive fields.

Stanley purchased Bailey, Chaney and Company in 1869 along with the Bailey plane patents. The Bailey patents were the key to Stanley’s future dominance of the hand plane market.

Stanley Rule & Level Co. purchased the Roxton Tool and Mill Company in Roxton Pond, Quebec (founded 1873). Manufacturing continued here from 1907 until about 1984. From the timing, I assume this was seen as a good way to get Stanley hand tools into the Canadian market without paying tariffs.

In 1920, The Stanley Works merged with the Stanley Rule & Level Company. The initials “S.W.” within a heart outline was introduced at that time. Later references to tools with this mark invariably refer to them as “Sweetheart”, but it’s not clear that the newly unified Stanley used that term in their own marketing until a few years later. The logo and name have been revived in the last decade or so, probably to cash in on the nostalgia factor.

In 1937, Stanley acquired J.A. Chapman (of Sheffield, England). I’m assuming this was a shortcut to getting non-tariff access to the British (and Imperial) hand tool market.

Stanley manufactured planes in Australia from 1965 to the early 1990s in Moonah, Tasmania.

In 2010, The Stanley Works merged with Black & Decker to become Stanley Black & Decker (Stanley Hand Tools is a division of the much larger company).

MILLERS FALLS (USA)

I happen to actually own a Millers Falls #9 smoothing plane (as of Friday). Look similar to the Stanley #4 above? It should, as it’s a near-clone.

Incorporated in 1868 as the Millers Falls Manufacturing Company, renamed as the Millers Falls Company in 1872. Introduced hand planes into its line of tools in 1928/29. Millers Falls chose to compete for the high-end of the hand tool market and managed to carve out a profitable niche for themselves, especially in the hand plane segment. Their futuristic plastic-and-chrome “Buck Rogers” planes of the late 1950s were visually distinctive enough that they kept the company in the black for longer than almost all of their US competitors.

In 1957, Millers Falls acquired the Union Tool Company of Orange, Massachusetts. The Union brand was kept active until 1975 when the Union plant was closed down.

Millers Falls became a subsidiary of Ingersoll Rand in 1962, and closed down their Massachusetts operation in 1982 with a corporate relocation to New Jersey after a buyout.

RECORD (UK)

(front) A Record No. 05 jack plane, a close copy of the Stanley #5

Record was a brand name used by C & J Hampton from 1909. The company was founded in 1898 and incorporated a decade later. The founders, Charles and Joseph Hampton, had left the family business (The Steel Nut & Joseph Hampton Ltd in Wednesbury, Staffordshire) to set up shop in Sheffield. Joseph eventually returned to the family firm, but the sons of Charles succeeded to leadership roles in the younger company.

The first Record planes were offered for sale in 1931 (No. 03 through 08 and three block planes: No. 0110, 0120 and 0220). Record got into the plane business partly due to the preferential tariffs the British government levied on foreign (mainly American) hand tools and the fact that the Stanley Works’ Bailey patents had expired, so there was no legal issue with flat-out cloning Stanley’s plane line.

In 1934, Record took over production of some Edward Preston and Sons Ltd. products (mainly bullnose and rabbet planes). Preston had been acquired by John Rabone and Sons Ltd. (Birmingham) in 1932, but they decided to stick with the rule and level business and offload the plane manufacturing to Record.

Woden Tools Ltd was purchased from The Steel Nut & Joseph Hampton Ltd in 1961 and Record continued to use the Woden trademark for another 10 years (some sources say only five years: take your pick).

Record acquired 50% of William Marples and Sons Limited in 1963, the other 50% being held by William Ridgway & Sons, Ltd. (Parkway Works), also of Sheffield.

In 1972, Record merged with Ridgway to form Record Ridgway Tools Ltd.

In 1982, Record Ridgeway was acquired by AB Bahco of Sweden, but a management buyout in 1985 took it back to British ownership as Record Holdings plc.

In 1988 the company became Record Marples (Woodworking Tools) Ltd.

In 1998, Record Marples accepted an offer from American Tool Corporation and became part of the Record Irwin Group as Record Tools Ltd. Irwin was acquired by Stanley Black & Decker in 2017.

WODEN TOOLS (UK)

A pair of Woden planes as shown on the wodentools.com website.

Woden Tools was a wholly owned subsidiary of The Steel Nut & Joseph Hampton Ltd, producing planes from 1953/54 in Wednesbury, Staffordshire. (The planes were originally manufactured by W.S Manufacturing (Birmingham), which was acquired by The Steel Nut & Joseph Hampton around 1952.)

C & J. Hampton (Record) purchased Woden Tools Ltd from SNJH in 1961 and continued to use the Woden trademark for another 10 years (some sources say only until 1965).

LEE VALLEY/VERITAS (CANADA and USA)

A current Veritas 5 1/4 junior jack plane from Lee Valley Tools

Founded in 1978 by Leonard Lee in Ottawa, Ontario. The first out-of-town store was opened in 1982 (Toronto West). I think I visited that store in its original location in 1984. The company launched their website in 1997 and added e-commerce features in 2000.

In the early-to-mid 1980s, Lee Valley contracted with Footprint (UK) to produce a line of bench planes to their specifications. The “Paragon” line were sold in Canada by Lee Valley and by Garret Wade in the United States for a few years, but quality issues apparently doomed the venture. In a thread on the Sawmillcreek.org forums, Robin Lee said “Actually – we ‘remanufactured’ many of them here [in Ottawa]… We set out the specs, made some tooling changes, and had Footprint make them for us (and GW). All planes were received and inspected … – and in many cases, fettled and reground… We abandoned the brand shortly after – and formed Veritas tools as our manufacturing company…”

In 1999, the first Lee Valley manufactured plane, the Low-Angle Block Plane, was introduced. The Veritas line of bench planes was launched in 2001. The first shoulder plane was introduced in 2003. In 2014, the Veritas Custom Bench Plane line was introduced, which the company characterizes as the first user-customizable line of planes in the industry.

In 1982, the company began manufacturing its own tools under the Veritas label. In 1985, Lee Valley Manufacturing Ltd. was incorporated and later renamed as Veritas Tools, Inc. Manufacturing is primarily in Ottawa and (possibly) in Ogdensburg, New York.

Differences in interest drives gender disparity in STEM fields

Filed under: Education, Science, Technology — Tags: , , , — Nicholas @ 03:00

David C. Geary and Gijsbert Stoet examine the STEM fields’ renowned gender disparities:

Many academics in the modern world seem obsessed with the sex difference in engagement with science, technology, mathematics, and engineering (STEM) fields. Or rather they are obsessed with the fact that there are more men than women in some of these fields. There is particular concern about the lack of women in prestigious STEM fields, such as Ph.D.-level faculty positions, but surprisingly there is no concern about the under-representation of women in lower-level technical jobs, such as car mechanics or plumbing.

The concerned academics have been especially effective in convincing others, or at least intimidating them, into accepting their preferred interpretations regarding the source of these sex differences (as illustrated in the Google memo debate). These interpretations are not surprising and they include sexism, stereotype threat, and more recently implicit bias and microaggression. Each of these ideas has gained traction in the mainstream media and in many academic circles but their scientific foundations are shaky. In this essay, we’ll provide some background on the STEM controversy and consider multiple factors that might contribute to these sex differences.

[…]

We’ve recently found that countries renowned for gender equality show some of the largest sex differences in interest in and pursuit of STEM degrees, which is not only inconsistent with an oppression narrative, it is positive evidence against it. Consider that Finland excels in gender equality, its adolescent girls outperform boys in science, and it ranks near the top in European educational performance. With these high levels of educational performance and overall gender equality, Finland is poised to close the sex differences gap in STEM. Yet, Finland has one of the world’s largest sex differences in college degrees in STEM fields. Norway and Sweden, also leading in gender equality rankings, are not far behind. This is only the tip of the iceberg, as this general pattern of increasing sex differences with national increases in gender equality is found throughout the world.

The recent uptick in interest in concepts such as stereotype threat, implicit bias, and microaggression may be a reaction to the low female STEM participation in highly developed nations. At one time, there were substantive social and educational impediments to women’s participation in these (and other) fields, but as explicit sexism and restricted educational opportunities faded into history, the sex differences (e.g., fewer women than men physicists) attributed to them should have faded as well. Some of them have even reversed, such that more women than men attend and graduate from college and women may now have structural advantages (e.g., hiring practices) in STEM fields. Even with these changes, many other sex differences remain or have become larger over time. The latter are serious problems for anyone with strong beliefs about purely or largely social influences on sex differences; if the obvious social causes have been addressed, then there must be other, more subtle oppressive factors afoot. This is where stereotype threat, implicit bias, microaggression and related concepts enter the oppression narrative.

We believe that with economic development and advances in human rights, including gender equality, people are better able to pursue their individual interests and in doing so more basic sex differences are more fully expressed. The differences in STEM are related in part to student’s personal and occupational interests and relative academic strengths. Sex differences in occupational interests are large, well-documented, and reflect a more basic sex difference in interest in things versus people. Men prefer occupations that involve working with things (e.g., engineering, mechanics) and abstract ideas (e.g., scientific theory) and women prefer working with and directly contributing to the wellbeing of others (e.g., physician, teacher). The sex difference in interest in people extends to a more general interest in living things, which would explain why women who are interested in science are much more likely to pursue a career in biology or veterinary medicine than computer science.

Programs designed to steer women into inorganic STEM fields would in effect steer these same women away from the life sciences. Such programs would, in our opinion, only be justifiable if women are not provided a fair opportunity to pursue inorganic STEM fields (for which there is no good evidence). The main argument from gender activists is that inorganic STEM fields are a better choice for women either because these jobs lead to higher incomes or that there is a labor market demand for them. Both arguments are fundamentally capitalist and dehumanizing in the sense that considerations of personal interest are overridden by considerations of societal demand. This is ironic, given that the agenda arguing for more women in STEM seems most popular among left-leaning people.

QotD: Computer models

Filed under: Economics, Quotations, Technology — Tags: , , — Nicholas @ 01:00

How can one be certain about outcomes in a complex system that we’re not really all that good at modeling? Anyone who’s familiar with the history of macroeconomic modeling in the 1960s and 1970s will be tempted to answer “Umm, we can’t.” Economists thought that the explosion of data and increasingly sophisticated theory was going to allow them to produce reasonably precise forecasts of what would happen in the economy. Enormous mental effort and not a few careers were invested in building out these models. And then the whole effort was basically abandoned, because the models failed to outperform mindless trend extrapolation — or as Kevin Hassett once put it, “a ruler and a pencil.”

Computers are better now, but the problem was not really the computers; it was that the variables were too many, and the underlying processes not understood nearly as well as economists had hoped. Economists can’t run experiments in which they change one variable at a time. Indeed, they don’t even know what all the variables are.

This meant that they were stuck guessing from observational data of a system that was constantly changing. They could make some pretty good guesses from that data, but when you built a model based on those guesses, it didn’t work. So economists tweaked the models, and they still didn’t work. More tweaking, more not working.

Eventually it became clear that there was no way to make them work given the current state of knowledge. In some sense the “data” being modeled was not pure economic data, but rather the opinions of the tweaking economists about what was going to happen in the future. It was more efficient just to ask them what they thought was going to happen. People still use models, of course, but only the unflappable true believers place great weight on their predictive ability.
