Paid better too

Schools just don't teach a person to be a good programmer. It really is about the person. I remember reading that programmers without a degree often make more money than those that do.

I do know that many of the people I've known that taught programming wouldn't make it in the real world outside of academics.

Update: speaking of teaching and income, shouldn't we teach kids about investing as part of general knowledge?

How fortunate are we?

They have lowered the estimate of earth threatening asteroids.

What struck me was how circular earths orbit is compared to both mars and venus.

Business model for mars settlement

For me, this was the exciting statement to read...

"Apparently [SpaceX is] proposing a business venture for a Mars settlement."

While the linked article had great information, I was a bit disappointed that it didn't really include a business model. However, we do have another data point for a business model...

Musk suggested a ticket price of $500,000 per person.

So here's my business model...

They put together a group of banks willing to support a mars settlement charter.

That charter specifies the conditions of a loan to anybody that wants to go to mars... anybody! They don't even need good credit, all transactions will be within this group of banks ensuring payments of the mars settlement loan package will be paid.

Assume one million dollars to travel to mars fully supplied for two years (this assumes Musk is giving a lowball figure and life support is non recycled.)

Assume a half hectare (time to use metric rather than non metric acres) plot developed for habitation is included in the travel package (life support for three.) This plot is selected by the traveler from a catalog of completely developed plots (with specified parameters) and purchased from an earlier traveler that has organized the work to completion on mars from a part of his own one square kilometer claim. Every person with boots on mars can make a single claim. This is legal by historical precedent. Everyone part of the charter will enforce this.

The bank gets paid immediately from the sale of this plot so the traveler has no down payment to make. A willingness to go and work in support of the charter is all that is required. They are free do to anything else they desire.

Suppose it cost $50k in material from earth to develop a habitable plot and six months of labor (another $50k.) They sell the plot for something in the neighborhood of $200k. The settler getting $50k and the bank getting $50k toward the payment of the mortgage loan. Assume 80% utilization one square kilometer provides 160 half hectare plots (from 400 quarter hectares.) This provides a potential eight million dollar return on a one million dollar investment. Plenty of room for banks and settlers to make a deal that works.

SpaceX has what it takes to make that work. Banks have an incentive to make it work. This provides a life time of income for the settlers. What's the hold up?

Update: Why this is not a Ponzi scheme...

Children will eventually be born and grow up and marry on mars. Which should have a vibrant economy by then. Suppose a couple buy a developed plot for themselves for $200k (the kids are moving out of the house folks.) This is not part of a mars settlement loan package; it's in addition to it. The two are paying only $100k each rather than a million each (no addition mortgage requirement on them.) They each have also gotten their own undeveloped one square kilometer claim... until the 144 million square kilometers on mars runs out. They could of course build rather than buy. Same choice as on earth.

Update 2: Where is this young couple going to get $200k for a home of their own? They have collateral: two square kilometer of undeveloped land. Their will be plenty of work to provide income to pay back a mortgage. This second generation will also have less debt burden. Ownership of real estate distributed among a population is the most important factor in economic growth. Too bad we can't learn that here on earth.

A physical threat of violence

My cousin 'Deano' (by my mothers marriage to a big family) came into my room and threatened me today. He was some what drunk which tends to bring out the belligerence in him. He's never done that to me before but has shown anger to others in the household. Worse in some ways is he lied to my aunt in saying that I was saying contemptuous things about my aunt in an attempt to create some bad feelings. My aunt and I get along well so I don't see anything coming from that.

I do not like being threatened. I am certain the threats might potentially lead to some dangerous confrontation. If you don't count him standing over me waving a glass beer bottle at me while being belligerent. He wasn't interested in listening to me, but I told him if he kept it up I would call the police and have him arrested. I tried to use a firm calm voice that would get through his beer fog. I'm not in good health and would really like to avoid any attacks coming from him. I'm really not sure how I should handle this going forward since we both live in the same house. I'm going to be locking my bedroom door more often in the future. I would not live under such conditions if I had the financial ability to do otherwise. I may have to change my living conditions anyway which would be difficult.

It's very disappointing. I'm going to wait to see if this just blows over.

UPDATE: I talked to the cops. They said they couldn't do anything because nobody was physically hurt. Then, I went over to my aunts daughter, the only cousin I trust, to compare some notes after she got home from work and fed her kids. Between us we discovered another important point. Deano has been playing Wormtongue with my aunt for at least the past month concerning the both of us in different situations. She hasn't been coming by as often as she used to and Deano turns out to be the reason why.

I've considered leaving, but it would be better for both my aunt and her daughter if Deano leaves. He thinks of himself as a chess player, but he just made a huge blunder last night. In this civilized world, perhaps a person can't defend themselves, but if I do end up in the hospital I can make damned sure the cops do their job.

Hit piece too subtle-y?

Sarah Palin says, "Does a title shackle a person?"

Sheila Marikar titles her article... Sarah Palin: ‘Is a Title and Campaign Too Shackle-y?’

It's probably an attempts at humor riffing off of 'hopey/changey'

How about giving serious consideration to the question? No need perhaps. Sarah will do it for this reporter.

A Great Speech

Just read it. A review.

The truth about Pakistan

Ally or enemy? Do we still consider those that kill our citizens to be enemies. If so, they are enemies (with nukes.) We have a low opinion of Saudi Arabia for paying terrorists to leave their government alone. Why is it different that we do essentially the same thing with governments around the world, including Pakistan? Are the friends of our enemies our friends?

The world isn't afraid of offending America with actual threats. They have more than boxcutters. Will the first nuke of American soil be from Pakistan?

Best Obama quote:

Obama is great at math. He divides the country, subtracts jobs, adds debt and multiplies misery.

China and IP

China is booming and does not support intellectual property. What does that tell us?

I would not presume to say at this point, but it's worth thinking about.

Gary Johnson?

I'm watching him on Cavuto right now. I like him. Will he be able to shake up the debate tonight?

He is sounding solid to me. I haven't followed him before.

• He says he would have a budget with lower spending and use his veto.
• He's for the fair tax.
• As president he could attack burdensome regulations starting with Obamacare.

He's not very charismatic and don't know if he can get support. Tonight's debate, his first, is very important for him. The media has already anointed the two front runners, the lazy bastards.

his first response always was to ask if government should be involved in that to begin with

I really like him.

Update: Could be the best answer of the night. Gary said something like "my neighbors two dogs have created more shovel ready jobs than Obama."

Update: Everything you need to know about Gary. He's too honest to be a politician.

False logic of the social contract

Elizabeth Warren says...

“You built a factory out there? Good for you. But I want to be clear: you moved your goods to market on the roads the rest of us paid for; you hired workers the rest of us paid to educate; you were safe in your factory because of police forces and fire forces that the rest of us paid for. You didn’t have to worry that marauding bands would come and seize everything at your factory, and hire someone to protect against this, because of the work the rest of us did.

“Now look, you built a factory and it turned into something terrific, or a great idea? God bless. Keep a big hunk of it. But part of the underlying social contract is you take a hunk of that and pay forward for the next kid who comes along.”

Sounds good, but is it right?

the rest of us paid for

Didn't the factory builder also pay taxes to build those roads? Educate those people? Pay the salaries of police and firefighters?

The presumption is that factory builders are taking unfair advantage of others when in fact they are risking their own capital. We should be encouraging this, but they want to penalize this and it is class warfare no matter how well you disguise it. Is it any wonder the economy is in the dumps with idiots like this in charge?

Those factory builders have to compete with other factory builders for customers (unless the government picks winners and losers using stolen tax money to do it.)

All Lizzy is doing is justifying theft by using envy. Pure and simple.

You don't have to believe that business people are saints, but it's much worse to demonize them and use that demagoguery to get people supporting this idiocy. The demons are the crony capitalists working with these politicians.

Even if you agree that the 'rich' need to be taxed more, knowing it will do nothing regarding out of control spending... when does it end? Everybody is being taxed too much to support out of control spending. How do you like paying payroll taxes that will never provide social security down the road? Isn't that a road we've all paid for?

Update: Now over at Rand and Goldberg and PJM Tatler.

Injustice dept. fights another southern state

I thought redistricting was a states right?

2 million spies

You'd think they'd be noticed.

How blind is the media?

in the summer and fall of 2008, with dozens of reporters descending on Wasilla looking for background on Palin.  Actually, “background” is too nice a word for it; they were looking for dirt.

Yes. If the media did there job it would be old news to everybody that Sarah Palin has been fighting corruption (and winning the fight) for years.


It long over due we slapped them in the head with facts. Wake up. You're being called lame for a reason. Undeserve it.

The hollow president

It seems the president is as amazed as the rest of us.

Crisis Solved

The slump in the United States and other advanced economies is the result of a failure of demand — period, end of story.

There ya go. That putz, Krugman has solved everything. He said end of story didn't he? Could there be more?

How about a business environment of crony capitalism and no rule of law? Might that also have something to do with it? How about a president that calls employers evil for not doing their fair share and wants to rob them of the means of creating jobs? How about idiots like Obama and Krugman that think magic money comes from wishing and unicorns farts rather than hard working taxpayers?

So Krugman, STFU.

Time for some political judo

Judo uses a persons imbalance against them. Obama wants to tax the rich. It's time to let him. The rich aren't going to be taxed no matter what the rate. Yes, the poor will be hurt, but that's the point. Let it be even more obvious than now how bad Obama's point of view is so we can finally be done with it. I'm one of the poor. I can take it until the next election.

The next president, regardless of who, will have failed on the first day if they don't fire the entire justice department and replace them with people that will hold faith with the rule of law. The present crowd should all get jail time for the obstruction of justice. Never again should we allow such people to hold the reins of power.

Update: Obama's non proposal, proposal. It's result.

Nothing new under the sun

corruptissima re publica plurimae leges

.OR.

When the republic is at its most corrupt the laws are most numerous

We have a lot in common with that old republic. We don't seem to have learned from it.

Panels or Power?

Which is a better business model, selling solar panels (Solyndra) or selling solar energy? I'm thinking energy has a better market, but solar only works during the day.

Not a big problem since we use more energy during the day. I just shut down my air conditioning until next season, but others will take up the slack no doubt.

But why is the government picking winners and losers? Doesn't that screw up the economy which corrects itself if left alone? That was rhetorical.

The fact is loans and loan guarantees are about getting political payola. They have absolutely NOTHING to do with making life better for taxpayers. We have got to end this corruption. Only Sarah Palin is focusing on this... as she did for the people of Alaska which gave her an approval rating in the 90s. How is the O doing?

Three for Thanksgiving?

Yesterday half the ISS crew returned home. Russia says they've fixed their problem so the next crew should go up Nov. 14th, but if not the ISS will be vacated Nov. 22nd.

SpaceX needs crew on board to do their demo resupply mission. Ironically, they could also deliver crew (w/o a launch escape system for now.)

Once there they become a more capable lifeboat that could remain on station longer and bring back more astronauts at a time adding to the safety of being on the station.

But they don't get paid until NASA gets it's act together. I bet they negotiate a better contract next time. Having more than one destination would be a good idea as well.

Every single one

Should be fired by the next president and replaced with people that support the rule of law and equal justice.

Crony Capitalism on Steroids

I think she has a winner.

Is that a subliminal message?

The Palestine Liberation Organization's ambassador to the United States said Tuesday that any future Palestinian state it seeks with help from the United Nations and the United States should be free of Jews.

We should ask if he's "For it."

Update: Even better.

Skinny

All too skinny for my tastes, but if I had to choose from this selection:

How long do we have...

...before we must be a space faring society?

Population growth on earth must end at some point. Energy growth as well. It must find an equilibrium. According to this graph...

...we have about 200 years left. It becomes a critical issue before the end of this century. I believe the next ten years will show the human race is on it.

No Bailouts: including the USPS.

I will be sad to see it go but I believe in creative destruction (Schumpeter not Marx or cash for clunkers.)

That the lead paragraph points out that Obama calls for passing a bill that doesn't exist is so funny and tragic.

Romney low blows Perry

I like politicians that are fighters, but not liars. Perhaps liar is going too far. He's definitely using scare tactics. Update: I have to say, giving the flyer some more thought, while it misrepresents Perry it does look effective. Like I said, I do like fighters.

I do not support Perry. He has some good points, but we need much more. I'm waiting for Sarah to announce this month. She's the real deal.

Sarah has her faults, but none the media and idiots have attacked her on.

Two good signs

Lots of good photos of a 9-11 protest including the first that has a sign that makes it clear the intent "ISLAM WILL DOMINATE THE WORLD"

The second sign is the fact that there was a Muslim counter protest...

A small group of Muslims staged a counter-demonstration nearby, holding up placards reading 'Muslims Against Extremism' and 'If You Want Sharia, Move To Saudi'

We need many more of that second group and I wish them well.

Redistricting; get the pop corn

We the people won in 2010 which leads directly to the fun.

We have a long way to go to root out the anti-Americans of both parties. This is a step in the right direction.

America

America is a country unlike any other. It is exceptional.

There are two rights from which all others are derived: Liberty and property. The governments ONLY job, and the very reason it exists, is to keep us each secure in these individual rights. A government faithful to these rights needs no enumeration of them.

The right of speech or thought or belief is the right of liberty.

Nobody would be debating if the right to bear arms were an individual or collective right. As long as a person doesn’t use weapons to deprive any other individual of their rights, the government should have nothing to say.

It would be understood that the government has no right over your property, not just for the quartering of troops without your consent.

You would be secure from search and seizure without some evidence of a crime and even then only by proper procedure specifically outlined and followed.

The fifth amendment is about the liberty to withhold consent. Eminent domain violates this principle of liberty and property.

Miranda rights, are not rights per se, but are a specification of a process to secure our rights from abuse.

Trial by jury is also a process to protect rights from abuse by the powerful.

Would we need to say protection from cruel and unusual punishment or excessive bail would be required if we held faithful to securing individual rights and really had a presumption of innocence?

The ninth and tenth amendments just restate what should be obvious.

We don't get our rights from government. The government exists to secure our rights. Anyone that doesn't understand this should not be allowed to vote or hold office. When a president talks in support of redistribution of wealth he has disqualified him or her self from holding office which requires defense and protection of the constitution. Nothing more needs to be said at that point.

Any law that isn’t both necessary to protect individual rights or properly balances the rights of individuals is unconstitutional. Equal protection means that state laws also needed to follow the necessary and proper rule.

Nobles do not define our rights. We peasants have inalienable rights no tyrant or government has the right to take away.

On this tenth anniversary of a despicable cowardly attack on America I pledge to defend my fellow peoples that hold these truths to be self evident to my very last breath.

Our dead will not be forgotten, nor those that cheered their death.

"I know who the enemy is"

3000 Americans died. For some, this was a cause for celebration.

I will never sleep until it is over.

About emotions

I think they are all valuable but as has been correctly pointed out, they can be hazardous.

Emotions can both paralyze and motivate. They often cloud judgement.

Most important is they can be an important signal that should not be ignored.

You can define an animal as all emotion and no thought. We need to aspire to something more than animal.

I'm a person that literally sees red when angry. But even in that worst case I never lose my reason. I'm baffled that so many people seem to have no reason to begin with.

I was a big kid who for some reason got into a lot of fights (I never started one ever) in grade school. When forced to fight my main concern was not to hurt the guy. I always ended up on top. Like I said, I was a big kid. It was emotional. I cried.

Once I was in class and a kid came in to confront me at my desk at which I tried to ignore him. The teacher put down his chalk, bounced the kid out of the class, then returned to his chalk board. I can't help but laugh every time I remember it.

Anger is one of those emotions less appreciated. Most angry people are idiots to be sure, but anger is no more or less valuable than any other emotion. What signal does anger send us? It should help to teach us what to hate. We need to hate what is bad or we end up encouraging it.

All it takes for evil to triumph is for good men to do nothing. We need anger and hate in proper measure and focus. We need it to survive evil.

Reagan Democrats

Sarah knows what it takes.

Bush Doctrine... again

With the tenth anniversary of 2001-9-11 coming in two days the media is again talking about the Bush Doctrine  as if they know what that means. Doing that makes them feel smart, but if they had to define the so called doctrine all that assumed intelligence would evaporate. That's because, as Wikipedia says, "various related foreign policy principles." In other words, there is no distinct "Bush Doctrine."

The media idiots think it means preemption. As Sarah explained correctly to that Gibson guy looking down his nose at her over his glasses... International law has always allowed preemption where a threat exists. You are not required to sit and take it until damaged.

As smart as Sarah

Yup, that's what I want to be. I just got one of the books she read in the mail today from Amazon, "Saving Capitalist from the Capitalists." I'll let ya know.

Update: Finished reading it last night. It didn't say much I didn't already know. I was a bit disappointed. It underwhelms. The take away is that free enterprise is fragile to political shenanigans. Duh!

I have a few books by Thomas Sowell which are better at describing the problems and solutions.

Only idiots believe this sentence.

Do you believe that sentence? Read it again.

Via.

But I can't help but see the divine.

Just an observation

Archie Bunker was how the left saw right wingers in the 70s. Watching 'The Five' on Fox I'm struck by the one member that both looks and acts light Archie. Right, their token liberal.

Update: Another observation...

Government likes oversight and punishing common folks. At the same time they waste taxpayer money with no apparent oversight or punishment of their own. It's time to shake them up. 2008 was only the beginning.

Another sickening speech

His labor day speech is an example of why I don't listen to our demagogue in chief Obama.

He is destroying the middle class in this country and claiming the opposite. This speech was pure bullshit from beginning to end. It's just too much.

We’re going to see if congressional Republicans will put country before party.

He broke the irony meter with that one.

...that really mean the right to work for less and less and less.

No, it means letting the free market set the rate rather than thugs.

This is the stump speech that will play well with his thugs.

Docking

Sounds like a simple thing. Connect two spacecraft with an airtight mechanical seal that allows transfer of people and cargo between vehicles. Not when the geniuses do it.

They don't seem to appreciate the power of simplicity. First, it should be the same for all so somebody doesn't get a call, "sorry, your child, sibling or parent died because we were idiots." The same for all means androgynous rather than a master/slave difference. Simple means it should not include connections for fluids or electricity. Cables and hoses should not be a part of the design. That works against it's main purpose. It means they add explosives so they can disconnect in an emergency. If you keep it simple enough, no emergency requiring explosives would ever be required.

So, because this hasn't been the focus we have different docking adapters that don't work together and may lose the I.S.S. as a result. How much do we pay these guys?

Secondary ports may have different designs, but one primary port should be standard and identical to all others.

Berthing, as opposed to docking, just requires a flexible cable/hose with a standard androgynous connector at both ends. Include a robot if people are not going to make this connection.

This doesn't seem too objectionable and includes power connections. Simpler would be better.

UPDATE: So what would I do? Take the above and remove everything except a metal ring of a standard size and the two seals. Then add docking clamps to replace the guide petals. That's it. The docking clamps ensure rotational alignment and concentric mating and should deploy mechanically like a railroad boxcar. The clamps should hold tight enough to seal and overcome more than any expected forces. The release mechanism should be simple enough that explosives are never a consideration. No magnets, electrical connections or hook latches that might not release. I would include a chamfer inside the ring for sealant (stock sealant itself) to replace or backup damaged seals.  No pins and holes, although permanent connection is allowed by welding or bolting (drill your own holes.)  None of this affects how the dock is extended between vehicles which can be handled in any way that makes sense and does not require standardization.

Hoses should have a simple connector at each end. They don't need any valves to close them off. That would be part of the hoses they connect to which allows venting to vacuum before releasing the hose for storage. Power plugs should have one male and one female pin at each end. You can't get that wrong. It's a universal extension cord. That would actually work quite well here on earth as well.

Ok, so I'm a lousy artist and the tabs may be on the opposite sides or unneeded.

We are governed by a permanent political class

Who govern by crony capitalism. This is the capitalism of connections, handouts, and influence peddling.

This is not free enterprise.

We need sudden and relentless reform [which] requires deeds, not just words.

1. Enforce the 10th Amendment.
2. Repeal Obamacare.
3. Prioritize and cut spending.
4. Have a robust and responsible domestic energy production.
5. Eliminate all federal corporate income tax, corporate welfare and tax loopholes.

Read the rest.

We need her because of her record of facing down crony capitalism as an executive and winning.

Broke my code

That's how you make progress. I'm going to allow a single claim per player which becomes their home world. Until they do that, they can explore the galaxy to find a suitable world. Creating a balanced economic system is going to be difficult. I intend the game to be free to play but with incentives to purchase in-game money to advance your player. Many players will never need to. Onward...

Thunder Lozenge

Thanks to Eric Weder for the link.

It's an ugly looking thing, but is only a first stage as I understand it. Replace the top with something like the Shepard which would then achieve orbit. Once in orbit, that second stage would become a SSTO for lower gravity rocks like the moon. For a billionaire, Jeff Bezos and Blue Origin does seem to be moving kind of slow, but then, they do have hardware flying so I won't give them too much grief.

That a supersonic flight instability destroyed it suggests they may need to rethink the shape of their vehicle.

SpaceX, as Mr. Musk's company is known, is years behind in testing its Falcon 9 rocket and Dragon space capsule

...the article says. I don't know (well, yeah I do.) Blue Origins was formed a few years before SpaceX, yet SpaceX has already been to orbit and retrieved their capsule in a spectacular (redefining the meaning of nominal) example of what they could do.

Going from suborbital to orbital is a big deal.

Wish my brain worked

I didn't get any coding done in the last two day. So today I will.

I used to be quite a great programmer. I'm not anymore. My brain just can't do it.

Still, I recognize crap code. That's something.

I went for the moon pizza

But this caught my eye. They make 'em tough in Alaska.

There is no government dime

Let's say half the money spent to get to orbit or beyond is government money. I really have no idea of the actual percentage. Of the $800m that SpaceX has spent in nine years, $300m came from the government. So perhaps I'm not too far off. Could space exploration and development happen if there was no government investment?

I hear the gasps. Did someone just faint?

The government is a fickled beast and tying your business to it can be haphazard. The I.S.S. may be abandoned before the end of this year. Where does that leave the $1.6b COTS contract awarded to SpaceX to resupply?

The fact is the government has no money and never did. All they do is redistribute the taxpayers money. Some might find themselves with a conceptual objection to this. Could we do space without govt. funds?

Yes. Because space has tangible assets that overwhelm the cost of developing them. Once we learn to live off the land we can colonize. Before we learn to live off the land we can keep people alive indefinitely with supplies at a cost that is within reason.

In space they call it life support... per person per day is about 8kg (0.9 oxygen, 2.6 food, 4.5 water) to be generous let's say 1000 kg every 90 days (one cubic meter includes packaging.) Add to that power and shelter. At that rate a Dragon mars lander could provide 900 person/days of supplies to the martian surface for about $100m. So we could support a dozen researchers on the martian surface before ISRU for less than half a billion a year.

Water and air can be produced from the martian atmosphere given hydrogen, a Sabatier reactor and power, but water itself can be found subsurface so you don't need a hydrogen source beyond that. 2.6kg is hydrated food, which could be as little as 0.7kg freeze dried means support for a mission of ten people could become as little as $50m per year. That is within the means of a small business or one wealthy person. Is there enough profit potential to make that happen?

Yes again. How? (...and who could go?)

Some have said a claim the size of Alaska could finance exploration... but that's a mistake. Healthy, robust economies require distributed ownership among all members of the society. It turns out that one sq. km. claims per person is all that is needed to finance any level of space exploration.

Colonists will require life support (habitat, power, food, water, oxygen, etc.) Colonists will arrive in a temporary habitat (like a Dragon lander) but will need permanent shelter. That permanent shelter may take six month to build and should be available the moment they land. That's a market.

Given a one sq. km. claim, colonists could develop plots (80 to 200) for resale to later colonists. The later colonists are going to have to pay for their shelter one way or another. Paying a few percent over cost to have it waiting for their arrival is a no brainer. As a matter of fact, it should be ready for them before they even leave earth as part of a package deal. Make claims only available to individuals means companies will have to buy their land from them, furthering stable economic growth.

Who could go? Anybody that wants to regardless of their financial situation because it can be financed so that the bank get's all their money from a previous colonists, including the money down for the trip. It doesn't matter what the cost because that factors into the cost of the real estate. The cost of real estate being the cost to develop it plus a small percentage profit. A home on mars should cost about the same as a more expensive home on earth which means the bank gets somewhere in the neighborhood of a million dollars down for every package they finance. While they might get a better rate of return on other investments they would have the privilege of opening up the frontier to an economic sphere that will, over time, dwarf that of the earth alone.
