Control T for TENEX

This magic works via detection of a STATUS control character, Control-T, by the kernel tty driver, which then prints the load line via tty_info() on FreeBSD or ttyinfo_locked() on Mac OS X. It also sends a SIGINFO to the process, so it can run its own routine. See STATUS in the termios(4) man page.

Prioritize practical movement

Natural human movement comprises locomotive skills such as walking, running, balancing, jumping, crawling, climbing, or swimming; manipulative skills such as lifting, carrying, throwing, and catching; and combative skills such as striking and grappling. In today’s comfortable world we are losing sight of the practicality of these skills, yet their value cannot be ignored whenever a life-threatening situation arises. You might have to run for your life, or climb, swim, fight, lift, etc. These abilities can save not only your own life, but that of strangers and loved ones as well. George Hebert said, “Be strong to be useful.” Do you want to be strong and useful? Then prioritize practical ways to move.

New knee ligament discovered. Again.

Orthopedic surgeons in Belgium have hunted down the enigmatic structure in cadavers. And what do you know — the good Parisian doctor [who discovered it 150 years ago] was right.

There is an overlooked ligament in the knee. And it might be important for keeping your knee from twisting and turning, especially after an injury to the anterior cruciate ligament, or ACL.

5 million tons of rubbish

Five millions tons of rubbish made up of devastated homes, boats, cars and businesses is making its way across the Pacific Ocean following the 2011 tsunami in Japan.

The article’s characterization of the debris as a “floating island” is certainly hyperbole. But still, this is a HUGE amount of floating debris.

You might try mowing the lawn

Researchers in Sweden measured the health of almost 4,000 60-year-olds in the late 1990s. A dozen years later, they checked back in. The people who had been active but not “exercising” at age 60 had a 27 percent lower risk of heart attack and stroke over that time, and a 30 percent lower risk of death.

What kind of activity does it take to get those kind of numbers? Things like mowing the lawn, housework, fix-it projects, gardening, bicycling, and, for a nice Scandinavian touch, “gathering mushrooms or berries.”

Repercussions

If I were in government right now, I would be leery of starting another big software project. I’d also know that big software projects are going to be necessary as our civilization gets more and more complex. So, if I were in government right now, I’d be thinking about laws to regulate the Software Industry. I’d be thinking about what languages and processes we should force them to use, what auditing should be done, what schooling is necessary, etc. etc. I’d be thinking about passing laws to get this unruly and chaotic industry under some kind of control.

If I were the President right now, I might even be thinking about creating a new Czar or Cabinet position: The Secretary of Software Quality. Someone who could regulate this misbehaving industry upon which so much of our future depends.

Maybe that thought hasn’t occurred to them yet. Maybe. But how many more healthcare.gov debacles will it take before it does?

Most people I’ve talked to, (who write software or do systems and network administration,) are in the “I have work to do” camp. They’ve no time to think about professionalization, or standardization, of their field. To which I say:

That’s cool; I understand. No worries! The government will eventually get around to ramming standardization and licensing down your throat. I’m sure that will work out well for us.

If you work in these fields, you should be paying attention. If you wok in network and systems administration, you should be paying attention to LOPSA and Usenix/LISA.

You are probably wrong most of the time

Q. Can you prove that I’m wrong?

Yes, but, you’ll have to agree in advance what proof looks like, otherwise you could just move the goalposts after the game.

Q. How come I have so much evidence that I’m right?

That’s confirmation bias. Your brain carefully files away all the reasons you might be right, and disregards all the reasons you might be wrong.

Do not go gently into that good night

We may not all achieve a high level of technical mastery enabling us to ward off the attacks of a skilled and aggressive opponent, even after many years of training. But, at the very least, we should be able to maintain a healthy life-style and keep our bodies flexible and well-conditioned even into advanced age. This is within the capacity of everyone and does not require any special genetic predisposition or extraordinary athletic skills. When many of us reach instructor level after a certain period of training, we gradually turn into passive supervisors rather than vigorous participants.

Mercy

Mercy is refraining from ridiculing or abusing the young men who lost 91-0. Mercy is complimenting them for their effort. Mercy is treating them like athletes and competitors after such a loss. Mercy is applauding when they return to the line time after time against hopeless odds, and when they return to practice again the next day. Mercy might be sitting down with them and telling them about times you lost badly and how you felt and how you got up again. Mercy is pointing out to other kids the character it takes to keep trying under such circumstances, and challenging them to have character like that. Mercy is teaching kids how to deal with the adversity they will certainly face in their life.

It is not merciful to teach them they have a right not to lose badly.

Our federal government has failed

The problem is not the problem.
The problem is your attitude about the problem.
Do you understand?

~ Captain Jack Sparrow

I think we need to reframe the problem so more people understand.

Civics 101: Are we on the same page?

I’m not going to discuss political parties. I’m not trying to sneak in the idea of “republican” to later make a case for a particular political party.

A federation is a government composed of several independent states. Each of the 50 current members of The United States of America are sovereign states which, through the process of their joining the union, have agreed to pass certain of their powers to the federal government. We, the individual people, are not members of the federation; The states are members of the federation. (May I recommend Wikipedia’s article on Federation?)

The distinguishing principle of a “republic” is that the activities of the government are public. To be a republic, the government cannot be arranged below a monarch, dictator (benevolent or otherwise), or some other (for example, a secret inner circle of corporations) inscrutable font of authority. (May I recommend Wikipedia’s article on Republic?)

The distinguishing principle of “democracy” is self-determination of the governed. To be a democracy, we need features that derive the government’s power from the governed people and that foster equality of each participant’s contribution. (Again, may I recommend Wikipedia’s article on Democracy?)

A pure democracy is one where the governed people may be fully involved in all decisions. A pure democracy of 300+ million people is absurd. But from the absurdity of pure democracy springs the idea of “representative” democracy. In this form of democracy, representatives are empowered to participate in the democratic process on behalf of the governed people.

The United States of America is a federation.
The United States of America is a republic.
The United States of America is a democracy.

By the way, “I pledge allegiance to my Flag and the republic for which it stands, one nation indivisible, with liberty and justice for all.”, is the original 1892 wording adopted by Congress.

The Federal Government Has Failed

Yes, exactly! Craig, I know what you’re going to say…
Our military is too big! (nope.)
The 1% is getting all the benefits! (nope.)
Too many people live in poverty? People can’t afford health care?! (nope and nope)
Look at the national monuments being closed!
…the IRS tax system?!
…immigration reform?!!
(nope nope and nope)

My definition of, “the government has failed” is: When I am expending increasing amounts of my time “on” the government. We, the governed people, are spending increasing amounts of our time on our federal government, and I put it to you that this is the ONLY thing on which every single American can immediately agree.

I want to be very clear: I’m not talking about spending more time interacting with the government. I’m not talking about time spent filing your federal taxes, or waiting in line at some federal agency. I am talking about time spent watching news about the federal government, reading posts, (including this one,) and debating federal policy, activities and programs with other people. Wouldn’t you rather spend your time doing, well, anything other than spending time on the federal government?

Some people have “tuned out” of the whole thing. This saves their time in the near future, but turns them into freight stored in the cargo hold of the ship; Their future remains coupled to the success, or failure, of the country.

As a democracy, a distinguishing feature of our government should be that it enables self-determination. If I’m spending increasing amounts of time on my self-determination, then I have decreasing amounts of time to enjoy the fruits of my self-determination.

Is this definition of failure useful?

If we can agree that the government has failed, then I think we can start a new discussion.

Instead of discussing any of the topics on which we’ve recently focused, we could instead discuss the very nature of our government. It would be a discussion which we – those of us alive today – have never actually had.

At some point, you were told where to register, and were told to “do your civic duty” by voting on certain days. But aside from a wee bit of civics required in high school, did you take the time to learn and care about the nature of our government? (I admit that I did not.)

If only we could agree on the nature of our government.

My hope…

My hope is that you’ll try to change the topic of discussion the next time some hot political topic comes up.

The current discussions are an endless train of political topics. Last year it was [this topic], before that it was [that topic], and next year it will be [this other thing.] You must know by now that in 5 minutes at the water cooler, you are not going to convince that other person to fundamentally change to your view of the current political topic. So you are clearly wasting your time “on” the government by participating in political discussion of the current topic.

Change the topic.

Talk about the nature of our government. Talk about why our government exists. Talk about the origin of its powers. Talk about what specifically are those powers.

…and if you don’t feel comfortable discussing the nature of our government, then why are you comfortable being governed by it?

Situation or character flaw?

There are two ways to explain mistakes: the person did what they did because of the situation, or, because of who they are. We use the former explanation with ourselves — “I forgot her birthday because I have so much on my mind right now.” We tend to use the second explanation on others — “She forgot my birthday because she’s so self-centered.”

What is a commutator brush?

So our washing machine quit this weekend (while I was away.)

“No user servicable parts inside.”

Not this user! Tools, snip, yank. A-HAH! The commutator brushes are worn out.

This is what my dad used to spend a lot of time on… changing commutator brushes on elevators; The thing in the picture with the “39B” on it, on the end of a braided wire with a spring to push it against the commutator… It’s a block of carbon (called a “brush”) and it should be about an inch long. :*) As the motor spins, it wears down. Eventually, the length of the cable limits it moving down against commutator, no electrical contact, no motor movement. The other brush, (motor has two brushes,) was still long enough to touch.

Physics/electrical geeks: Ask me about commutator brushes some time. :^D

Internet, click click click, order via drop-ship P1, parts for tomorrow. Washing machine back in business for wednesday.

80% more energy is all that is needed

[T]he world’s poor people are starving and dying for lack of cheap energy today. Driving the price of energy up and denying loans for coal-fired power plants is depriving the poor of cheap energy today, on the basis that it may help their grandchildren in fifty years. That is criminal madness. The result of any policy that increases energy prices is more pain and suffering. Rich people living in industrialized nations should be ashamed of proposing such an inhumane way to fight the dangers of CO2, regardless of whether those dangers are imaginary or real.

The little fears

For to practise parkour is to seek fear on a daily basis, to confront it head-on, to face it naked and alone. In parkour, you are stripped to your essence. There is no equipment to rely on, no safety harnesses or padding to protect you, no teammate to take the brunt when you are tired. It’s you, and you alone. The only things that prevent you getting hurt or injured are your skills, your judgement, your ability – no one else’s.
