Monkey bars

I used to play on the monkey bars all the time when I was a kid. My mom encouraged it. She knew it built upper-body strength, and that the ability to traverse monkey bars was an important capability for any human. (She could traverse monkey bars herself, when I was a boy.)

I quit doing the monkey bars, probably when I was college age, and quickly lost the capability. Then for three decades would have been afraid to even try, because I’d definitely have hurt myself. A few years ago I wanted to regain that capability, so I started looking for monkey bars to practice on, and found that they’ve gotten quite scarce. Many playgrounds don’t have them at all.

Winfield Village has a playground in every quad, but the only playground with any sort of monkey bars is the big one close to the office, and it has a rather strange curving monkey bar that over the course of 5 rungs makes a 90° turn—a particularly challenging version. (Like most these days, this one has weird triangular bars hanging from a single support, rather than a series of rungs supported on both sides.)

Bars for brachiating at Winfield Village playground

The reason for both the near disappearance and the switch to triangular bars seems to be that monkey bars are “dangerous.” Many playground safety experts recommend that monkey bars be excluded from playgrounds altogether, and I think the weird shape is designed to make them harder to climb on top of, in the hopes that kids would then not do so.

I spent a chunk of yesterday afternoon at an “alignment play day” with folks from CU Movement (and  kids), getting some hanging and balancing and barefoot walking on various textures. One thing I did was traverse the monkey bars at Clark Park in Champaign—an old-style set of monkey bars, rather like the ones I remember as a kid.

One of the kids in our group—small enough that it was a challenge to reach the next bar, and at a height that the experts would no doubt claim was “too high” for a kid of that size—did the monkey bars, and then immediately wanted to climb on top of them. He asked for help getting on top, which his mom declined to provide—except that she pointed out that one of the supporting poles could probably provide the necessary foot purchase for him to get on top on his own. And he did manage to find two ways to get up there. Having gotten up there, he decided against traversing the top of the monkey bars, and simply swung back down under them.

A new school of thought is emerging (finally!) that “dangerous” playground equipment offers valuable opportunities for kids to do exactly what this boy did: evaluate a hazard and decide how much risk was appropriate. The only way to learn to make that sort of evaluation is to actually practice it. Making playgrounds so safe that children cannot hurt themselves reduces their opportunity to develop a good sense for what is safe and what is dangerous, and what is and is not within their capability.

It has also made it a lot harder for me to find a set of monkey bars to practice on.

I crossed the monkey bars three times in the afternoon, but I forgot to attempt my next big trick: Cross from one end to the other, turn around (without putting my feet down) and cross back again.

I’ll do that next time.

What good is a militia anyway?

The reason that a well-regulated militia appealed to the founding fathers was that they hoped it would eliminate the need for a standing army.

If you had the whole body of young adult men armed and trained, it was hoped you could raise an army very quickly in case of need. If that were true, Congress could insist that the standing army be run down to just a cadre of specialists and officers. Then, in the event that you needed an army—because you were invaded, or needed to invade someone else—you could mobilize (i.e. draft) the militia to fill the ranks with soldiers.

The founders knew perfectly well that a government with a standing army could not be resisted by the people, even if the people were armed. A standing army was always going to be more disciplined, more highly trained, and better equipped than a militia could possibly be.

So, the purpose of the militia was to eliminate the need for a standing army. If you could make a militia work that way—quickly go from a bare cadre to a fully mobilized army simply by calling up the militia—then you’d be in a position where Congress could insist that the the army in fact be a bare cadre, meaning that neither presidents nor generals could use the army until Congress actually raised one.

It’s an appealing idea, particularly to someone like me who is very doubtful about trusting presidents or generals. Sadly, the evidence is pretty good that it doesn’t work.

This was clear even before the sorts of modern, high-tech weapons and other equipment that take extensive training to learn how to use, and then nearly constant on-going training to preserve the capability.  It took five years to go from a 16,000-man army to a 1,000,000-man army during the civil war. The ramp up for WW I was quicker but also smaller—manpower grew by 16 times in two years rather than 62 times in five years, but that was from a much larger base—basically, a smallish standing army, not merely a cadre waiting to be filled out.

The experience of the U.S., at least as far back as the civil war, is that fielding an army by mobilizing a militia simply can’t happen fast enough to respond to an enemy with a standing army. (The experiences of Switzerland mobilizing to resist a possible Nazi invasion and Finland mobilizing against the Soviet Union at around the same time are interesting, but do not I think make the contrary case.)

Given all that, I’d have to say that a militia is pretty much obsolete, and has been for a couple of centuries at least.

Losing a job

My friend Mart lost her job this week.

I know all about losing a job. Over the years I was fired or laid off four times.

Getting laid off is humiliating and insulting. The process is stressful and and unpleasant. The aftermath, where you have to deal with your feelings about the fact that other people kept their jobs while you lost yours, at the same time that you deal with having a sharply lower income, layers more stress and unpleasantness on top of that.

Losing a job is also frightening. It fills your future with unknowns.

The middle time I was laid off, my former employer hired an expensive outplacement firm to help us make the transition. We had a series of meetings at an off-site location where a counselor gave us advice on dealing with the emotional and practical issues. Although the somewhat simplistic advice was another layer of insult piled on top of the insult of being let go, it was actually pretty well done. I used what I learned there for pep talks that I’d give former coworkers when they were let go. I used it as the basis for part 1 (losing a job) of the Wise Bread series I wrote on getting by without a job.

These last few decades—as the whole economy has adjusted to eliminate the working-class jobs that used to provide a middle-class standard of living—losing a job has become even worse than it was back when I lost mine.  And yet, while losing a job is a pretty bad thing, but it’s not always purely bad. Even people who love their job don’t love everything about it. (Mart in particular, I think, loved books a lot more than she loved her job at a bookstore.)

Still, losing a job sucks, even if things go as well as possible after that.

Running my own server again

A year and a half ago, my brother gave me a Raspberry Pi 3 as a birthday present, suggesting that I should use it to run my own server.

I used to run my own server. A friend who liked to build such things had built it. It had two ethernet ports, one connected to my cable modem and the other connected to my WiFi router, and it was running OpenBSD (then the most secure OS easily available) and was configured to serve as a firewall.

I used it as a server in other ways. I put an extra disk drive (40 GB!) in it where I could store files that I might want to access from elsewhere. (In particular, when I went to Clarion I copied my latest draft of my current story there each evening, in case of catastrophic computer failure.)

It didn’t require much upkeep, but it required more than none—which turned out to be more than I wanted to devote to it. At some point a serious security flaw was discovered in the OpenBSD release I was running. By then most desktop machines had built-in firewalls as did most routers, and I had Time Machine as a backup solution. It seemed safe to give up my server, and easier than updating it.

In the years since then, the use of cloud services has become ubiquitous, to the point that practically everything I do ends up in the cloud—my photos go to both Flickr and Google. I also use Dropbox (where I have Scrivener stash a backup copy of everything I’m writing) and I stash some amount of my music at both Google and at Amazon.

That’s all great—those services are well backed-up, and the servers are very likely running the latest security patches—but I really like the idea of having my own data on my own machines. But I want that without giving up the advantages of having my data in the cloud. Hence wanting to have my own server.

All that as prequel to my brother coming to visit this past week, and helping me get my Raspberry Pi server up and running.

Once the basic install of Raspbian was up and running, I went ahead and ordered a bit of hardware for it. I got a short ethernet cable to connect it to my router, so that it doesn’t have to do WiFi for basic connectivity (although WiFi and Bluetooth are built in). I also got a slightly more powerful USB power supply for it, mainly because I also got a portable USB hard drive that takes its power from the USB port, meaning that the power needs to be available to the Raspberry Pi. Finally, I got a case for it, so that I don’t just have a naked circuit board sitting on my dresser.

This time the hard drive is 1 TB rather than 40 GB.

For cloud functionality I’m following my brother’s example and running syncthing, which has the advantage of being able to handle being behind a NAT and not having a port exposed to the outside world. I’m running it on my Android phone as well and sharing my photos with a third place: my server. The server then shares them with my desktop machine, so they’re available to use. (That’s how I got the photo above: Taken with the phone and then transferred to the desktop within about a minute.)

I’m still sorting out my sharing strategy. I don’t want to share my whole Music folder with my phone, because it would use all the space there. (I’ll probably end up making a folder with an “essential subset” of my music to share with the phone.) I don’t think I want to share my whole Documents folder on my desktop machine, but I’m not sure yet. For the time being I’m sharing a folder I call “Active writing” with the files I’m currently working on, on the desktop, the server, and my laptop. That way they’ll be available wherever I want to work on them.

Other things are tougher. I’d like to have my own calendar server, but that doesn’t seem easy. I should go back to my post on the google-free option and see what else I was thinking about that I might now be able to implement.

For now, though, I’m pretty happy.

My previous server was rack mount width and maybe four or five inches tall, about the size of a stereo component. This one is maybe 3 inches by 5 inches, rather smaller than the hard drive it’s sitting on.

Voting is a constitutional right

The right to vote is a constitutional right. It should not be abridged. In this way it is like all constitutional rights.

There is one important difference between the right to vote and most other constitutional rights. Most constitutional rights apply to “the people,” while the right to vote is a right of citizens. Because of that difference, it makes sense to verify that people registering to vote are citizens. But waiting until someone is at the poll and then demanding that they prove they’re a citizen is backwards.

It is, to use another constitutional right as an example, backwards exactly the same way it would be backwards to take your property for public use, and then make you run all over town for documentation to prove that you own it before you can get it back. Instead, we have a property registry to keep track of who has ownership rights, and then a process called eminent domain whereby the government has the opportunity to present to a court evidence that there is a public need for your property according to well-established rules, and to establish fair compensation. You have the opportunity to dispute that evidence, and to argue for a different interpretation of the rules or for higher compensation.

I would suggest that as being the right model for voting rights as well: We should have a voter registry to keep track of who has the right to vote, and then a court process whereby the government has the opportunity to prove that someone on that list does not have the right to vote according to well-established rules (not a citizen, not over 18, not residing in the precinct, dead). You should have the right to appear at the hearing and dispute both the evidence and the interpretation of the rules.

Nobody should ever be struck off the voter rolls without such a hearing—to my mind it would be just as unconstitutional as taking your property without a hearing.

If that is the standard—as it should be—then there is no need to present an identity document at the polling place. All you need to do is prove that you are the person who registered, which is easily done by comparing your signature when you request a ballot to your signature when you registered to vote.

In any case: The right to vote is a fundamental right of the citizen. Denying it without due process is wrong, and there should be substantial sanctions on anyone who does so (or attempts to do so).

Progressive policies with conservative rhetoric?

I wonder whether it would be possible to advance a progressive policy agenda that was cloaked in conservative rhetoric.

For example, it is currently legal for police to use unlimited force to produce compliance with their orders, even illegal orders. Essentially, you are forced to stop going about your business, comply with whatever the police tell you to do, allow them to search you and whatever you’re carrying, tolerate an indefinite delay, even let them take you to the police station if they chose, all without offering any sort of resistance.

Any questioning of their actions or inquiry into its lawful basis can be interpreted as “resistance,” and any degree of resistance, no matter how minimal, is considered legal justification for the police to beat you up, taser you, pepper-spray you, or even shoot and kill you—and they will suffer no consequence beyond (perhaps) a brief period of paid leave.

People of color have borne the brunt of these sorts of police actions for a long time. With the advent of ubiquitous cameras we have now seen many people of color murdered while offering up either no resistance at all, or such minimal resistance that it should shock the conscience to see lethal force used. We have also seen many white people granted great deference by police under circumstances where a black person would have been killed.

This is the circumstance that led to the “black lives matter” slogan.

Many people—especially, I suspect, many Trump voters—object to this slogan, preferring to suggest that “all lives matter.”

Many liberals and leftists look to a willingness to say “black lives matter” as a marker that you’re on the right side of this issue.

My question is, could a political candidate who was on the right side of this issue (and many other issues, such as using the threat of jail to balance town budgets on the backs of indigent people) couch his objections in terms that would not offend Trump voters, while still pushing for good policies? And would such a politician be able to get support from both sides of the political divide?

For example, I’d like to see a policy that said that resistance to an unlawful order from a police officer was legal and that any force used by the officer to produce compliance was an illegal assault—the officer should be prosecuted. I’d like to see a policy that any monies extracted from an indigent person under threat of jail be considered the proceeds of an illegal extortion scheme—everyone involved in the extortion should be prosecuted, the money returned, and the original fine forgiven.

If a politician were to propose such ideas, but describe them with terms like “all lives matter,” or “protecting liberty and private property rights,” could such a politician draw support from both sides?

I’m doubtful. But I’d like to see it.

Rodney Davis: Please take a stand against Trump’s immigration order

I just sent the following to my representative in Congress via the web form on his page at the House website:

Based on media reports and what I can find on your website and twitter feed, it appears that you have not yet taken a stand against Trump’s illegal and unconstitutional executive order blocking entry by nationals from certain countries.

Can I count on you to do so in short order?

I didn’t mention in my note, but wanted to mention here, that Davis’s words for his constituents after the recent election invoked Lincoln’s phrase “With malice toward none, with charity for all,” so I’m a little concerned that he may be putting a dangerous strain on our nation’s limited supply of irony.

I also refrained from once again pointing out that the Republicans in Congress are straight-up cowards, afraid of widows and orphans.

The Federal Reserve and the “gig” economy

The “gig” economy: all the sorts of work arrangements where you’re not a permanent employee and can’t expect that work one day implies that you’ll have work the next day—freelancing, contracting, temp work, casual labor, and most recently, software-mediated contract work like Uber driver.

These sorts of work have been growing as a fraction of all work. In fact, according to the Bureau of Labor Statistics, in the last ten years contingent workers have gone from being 10% of the workforce to being 16%. In fact,

all of the net growth in aggregate employment in the decade leading up to 2015 can be accounted for by contingent work arrangements, which means there has been no net employment growth in traditional work arrangements.

Source: FRB: Brainard, The “Gig” Economy: Implications of the Growth of Contingent Work

This matters to everyone with an interest in the U.S. economy, but it matters particularly to the Federal Reserve, which is charged by Congress to:

promote effectively the goals of maximum employment, stable prices and moderate long-term interest rates.

Source: The Federal Reserve’s Dual Mandate

So this raises the question: Does strong growth in the number of freelancers, on-call temps, and Uber drivers mean that we’re getting closer to maximum employment? Or, that we’re getting further away?
