Precisely. It is utterly insane for programmers to communicate with a database by constructing strings in an arcane language that is then compiled in real time. Not only does this open a whole bunch of bizarre, security holes, it’s just plain dumb. We are programmers, we communicate with our libraries using functions and data structures, not strings that have a syntax that was designed 50 years ago for non-programmers to use.

I’ve never used Mongo DB. I have no problem with the relational model per se. My issue with SQL is that it is text based and compiled in real time. That makes it a huge security concern. It’s also just really inconvenient for programmers to have to construct sequel statements using a text library. In general databases should be accessed through a software API — a library of function calls that are driven by data structures that cannot be compiled in real time.

2024-11-03T22:21:45Z

Why I voted for Trump.

During his first term:
* The economy was good,
* Worker's wages were increasing,
* We were energy independent and approaching energy dominance.
* There were no new wars,
* Immigration was decreasing and under control,
* NATO began to contribute their fair share,
* Peace was breaking out in the Middle East.

And the Democrats:
* Concocted the Russian Collusion Hoax
* Spied on his campaign and presidency.
* Impeached him for looking into Biden's treason.
* Suppressed the Biden Laptop.

I could go on. I'm happy to answer any questions.

I've donated a decent bit of money to Zeus development. I will no longer be supporting Zeus.

It's morally bankrupt to respond with derision to a Zelenskyy and others signing bombs that are keeping Ukrainians alive by killing Russian invaders. I'm in Kyiv right now – those bombs are part of the reason why I can even be here relatively safely. They're why people I know got their houses back after the occupation was pushed back; sadly they couldn't get their friends and neighbors back, because there's no fixing being murdered.

Then let’s throw the southern border wide open so that Venezuelan gangs and Islamic terrorists can pour, unimpeded, into the country.

Then, let’s make sure the cities elect radical prosecutors who will refuse to charge and hold criminals; making sure that those gang members and terrorists stay on the streets.

Oh yeah, and then let’s make sure the city legislators declare their cities to be sanctuaries that refuse to turn criminal illegal immigrants over to ICE for deportation.

Censorship guarantees that the only form of speech allowed is the form that is beneficial to the censor. Since power corrupts, and absolute power corrupts absolutely, then we are guaranteed that the power of censorship will lead to only corrupt speech.

On the other hand if a free exchange of ideas is tolerated -- even ideas that are terrible and hateful, then we can evaluate them all together and select those we wish to adopt. The bad idea will fall to the wayside as the better ideas gain success.

_________________________

All that comes from Maxwell's laws (which eventually derive from Special Relativity). A moving magnetic field creates a stationary electric field. A moving electricc field creates a stationary magnetic field, etc.

If we start with the premise that the neutron star is a spinning magnet then the moving magnetic field creates a stationary electric field aligned with the spin axis of the star. Any charged particle within that electric field will be accelerated along the electric field lines. Charged particles that move through a magnetic field are acclerated at right angles to the that field. That translates to circular motion around the magnetic field lines. So the combination of the electric field accellerating those particles linearly outward, and the magnetic field accellerating them circularly around the field lines, casues the particles to move in a tight spiral outwards.

Each such charged particle has it's own electric field which is being accelerated both linearly and circularly. This creates a circularly rotating magnetic field at right angles, which ceates a circularly rotation electric field, which creates a circularly rotation magnetic field -- or, to say this differently, an electromagnetic wave. The propogation of an electromagnetic wave is perpendicular to the axis of rotation of the wave, and is therefore outward along the magnetic field lines of the star.

I think I got that all right. ;-)

2024-08-22T17:49:14Z

The collapsing iron core of a massive star that has exhausted its fuel will quickly reach densities at which electrons and protons can no longer remain separate. They combine to form neutrons in an extremely violent reaction that tears the rest of the star apart and blasts it's contents all over the sky as a type 2 Supernova.

At the time of the explosion the structure of the star looks like an onion. There is an outer shell of Hydrogen gas, then a shell of Hydrogen fusing into Helium. Below that is a shell of Helium fusing into Carbon and Oxygen. Deeper still is a shell fusing Carbon into Neon, Magnesium, Sodium, and Aluminum. Deeper still is a shell fusing Neon into Oxygen and Magnesium. Still deeper the Oxygen fuses into Silicon, Argon, Sulfur, and Calcium. And finally a shell that fuses Silicon into an isotope of Nickel that decays into Iron.

All this material is blown to smithereens when the barrage of outrushing neutrinos produced by the core's transmutation into neutrons collides with those shells. The over-pressures cerated in that collision stimulate even more fusion. The environment of the explosion is rich with free high energy neutrons, and alpha-particles (Helium nuclei). These particles are absorbed by the elements within the explosion, transmuting them further into the vast majority of the elements on the periodic table up to element 36.

All these nuclei are scattered amidst the rapidly expanding cloud of debris and eventually mix with the interstellar medium, polluting the existing clouds of neutral hydrogen and, if close enough, stimulating them to collapse into planetary systems.

The Oxygen and Nitrogen in our atmosphere. The Carbon and Calcium in our bodies and bones. The Sodium in our seas, and the Iron and Aluminum in our buildings, originated from this process. Those elements all came from stars that blew their guts up all over the sky, and seeded future stars with the elements of life and civilization.

Most of the stars were see in the night sky are extremely ...

2024-08-20T13:15:06Z

Most of the stars were see in the night sky are extremely luminous giants. Stars the size of our Sun are too faint to be seen beyond a few dozen light years. This is ironic because the Sun is much larger than the majority of stars. There are a vast number of nearby stars that we simply cannot see with the naked eye.

Giant stars burn very hot, and very bright, and for a very short time. A giant can fuse hydrogen into helium thousands of times faster than the Sun. It can exhaust its fuel in as little as ten million years.

In their cores, they first fuse hydrogen into helium, then helium into carbon and oxygen. However, unlike the Sun they are massive enough to continue the process and fuse carbon into a number of other elements, that eventually are fused into silicon

At each stage the rate of fusion must increase because the reactions become less efficient.

On the very last day of a giant star‘s life, it begins to fuse silicon into iron. This reaction is so feeble that the star will burn through a full solar mass of silicon in a matter of hours; all the while a nugget of iron, the size of the Earth, with the mass of the Sun, accumulates in its core.

Fusion reactions with iron are endothermic. They consume energy as opposed to producing it. So when the silicon is exhausted, and the iron begins to fuse under the weight of the star above it, the core cools.

The cooling core collapses, it can no longer produce the energy needed to hold up the mass of the star. The collapse proceeds so rapidly that the material at the center approaches a sizable fraction of the speed of light. The rest of the matter within the star is pulled down with it at a slower pace.

When the core has shrunk to approximately 10 miles in diameter the pressures are so great that the electrons and protons within it are forced to combine into neutrons. This reaction creates a barrage of neutrinos heading outward at the speed of light. Meanwhile the neurons in the core rapidly arrange themselves into an energy shell structure that resists any further collapse. The collapse stops dead.

The outrush of neutrinos carries a vast amount of energy that is more than sufficient to reverse the inflowing matter of the star and blow it out into space at a fraction of the speed of light. This reversal creates temperatures and pressures that stimulate even more fusion within the outrushing guts of the star.

The explosion is so energetic that the dying star’s luminosity increases by approximately twelve orders of magnitude. For several weeks it will outshine the galaxy it lives in.

This is a type 2 supernova, and we don’t want to be close to one. 50 light years is not far enough. Within that radius the radiation slamming into the Earth would be disastrous for life. Fortunately there are no stars within that radius that are likely to blow up soon.

But keep your eye on Betelgeuse — it’s likely to blow in the next few thousand years — maybe tomorrow. At 500 light years it would put on a hell of a show. It would be brighter than the full moon and you could read by it at night.

The Sun, our local star, is just under a million miles in ...

2024-08-16T17:59:51Z

The Sun, our local star, is just under a million miles in diameter. The surface temperature is about 5,000K, and the power output is about 4E26 watts.

All that power is coming from the innermost 10% of the star -- the core -- where the temperatures are around 17E6K, and the pressure is ...um... crushing.

At those temperatures the Hydrogen atoms cannot hold onto their electrons. So protons and electrons are free to zoom about without binding. The velocities of the protons are so high, and the pressures are so great, that every once is a great while two protons will get close enough that the strong nuclear force will bind them together into Helium. This happens to about 500 metric tons of Hydrogen each second. In that reaction a lot of high energy gamma rays are released.

Those gamma rays are trapped within all those charged particles in the core. They bounce around in the core, doing a random walk for thousands of years. But eventually they reach the outer shell of the core where they can heat the Hydrogen gas outside the core.

The bouncing around of all those gamma rays creates an outward pressure that keeps the core of the Sun from collapsing under the weight of the Hydrogen above it.

The hydrogen outside the core, heated by the gamma rays escaping the core, rises to the surface of the star in a massive convection current. Upon reaching the surface, the heat of that gas is radiated at 5000K and reaches us ~8 minutes later.

This process has been going on for nearly five billion years, and will continue for another five billion or so. However...

The Helium building up in the core takes up space. This impedes the fusion reaction. Fewer gamma rays are produced, causing the core to contract. This heats the core driving the fusion rate back up, but at a slightly higher temperature.

Thus, the Sun is gradually warming. It is about 10% hotter today than when it formed, and it will continue to get hotter and hotter as the eons pass. In about 200 million years, it will be too hot for water to remain liquid on the surface of the Earth.

So, I guess we'll have to move the Earth a bit farther out.

2024-08-14T18:45:55Z

We are currently in an ice age, which is defined as any period during which there are ice caps.

The current ice age began 2.5 Mya. It is suspected that the cause was the gradual reduction in CO2 caused by the weathering of the Himalayas, the migration of Antarctica over the South Pole, and the closing of the isthmus of Panama blocking ocean heat transfer at the equator.

There have been over a dozen significant glaciations since the ice age began. They are likely driven by the orbital cycles of the Earth. In the last million years they’ve fallen into a regular pattern of ~90,000 years of advancing cold and ice, and ~10,000 years of retreating ice and relative warmth. We are in one of those warm periods now. It started ~12,000 years ago.

Winter is coming.

If the idea of curved space time, as described by General ...

2024-08-13T18:47:17Z

If the idea of curved space time, as described by General Relativity (GR), confuses you, consider the following analogy.

The theory of GR was sparked by Einstein’s “happiest thought”, that gravity and acceleration are equivalent.

That means that you, standing on the ground, are accelerating upwards. But you can detect no motion in that direction. How does that make sense?

Consider the amusement park ride sometimes known as “The Rotor”. It is a room sized cylinder that you walk into and stand against the back wall. Then the cylinder is spun up and you are pressed against the wall by centrifugal force. For you, gravity seems to shift and you feel as though you are lying on your back with the center of the cylinder above you.

Your acceleration vector is toward the center of the cylinder. But your velocity vector is parallel to the back wall, 90 degrees away from the acceleration vector.

So, when you are standing on the ground, accelerating upwards, your velocity vector, as you move through curved space time, is shifted 90 degrees into the dimension of that curvature, which is a dimension you cannot directly perceive.

It is an irrefutable fact that a society that does not value the having and raising of healthy children must end in ruin.

It is therefore also irrefutable that a political ideology that
* supports the killing of children before they are born,
* the sterilization of children after they are born,
* and the indoctrination of children, to avoid having children of their own in pursuit of more selfish goals,

will lead their societies towards ruin.

2024-06-29T13:17:02Z

The Debate:

Trump was recognizably Trump -- though perhaps a bit more reserved and focussed than usual.

Biden was a pale shadow of his former self. Frail.
Halting. Confused. Addled. Almost unrecognizable from the fiery joke-and-gaffe peddling VP he was under Obama.

When I saw Biden walk in and heard his mumbling answers my jaw almost hit the floor. I grabbed the armrests of my chair and leaned forward in bug eyed amazement. Jesus! I had not expected _that_!

The media panic is palpable. Virtually every previously staunch defender of Biden who backed the "Cheap Fake" narrative, from Morning Joe Scarborough, to the ladies of the View, have thrown Biden under the bus demanding a new candidate.

The media have tried to accuse Trump of lying and lying and lying; but that's not what I saw. Biden certainly told a bunch of whoppers, like no troops were killed on his watch, or the tired old "very fine people" baloney that even Snopes has had to debunk. But Trump, while often vague and/or hyperbolic (recognizably Trump) provided a set of facts that match observation. Yes, Afghanistan was a disastrous embarrassment. Yes, illegal immigration is a horrific problem. Yes, inflation is horrible. Yes, under Trump we had a stronger border. Yes, there were no wars under Trump. Yes, the economy was much better under Trump. Yes, we were energy independent under Trump. The list goes on.

The bottom line, from my point of view is that Trump won the debate on _substance_. Had Biden's delivery been more youthful and energetic, he still would have lost on the substance.

No. It's an asymptotic goal. You'll never get all the way there; but you can get to the point where you trust the test suite enough to deploy the system without fear.

A refactoring is a small change to the code that improves structure without changing behavior. So, theoretically, a refactoring will not create such an "edge case". Realistically, however, such things _do_ occur. You have to be careful.

Still, it is possible to create a test suite that robustly resists most such "edge cases" and that you trust well enough to deploy without fear.

This sounds pretty interesting to me. I want to be able to put a nostr client into "test mode" which opens up a socket that the client listens on. The CI acts as a relay and tells the client to use only that relay. The CI sends commands to the client that spur it to perform certain actions; and the client uses the CI as a relay to perform those actions.

Interesting.

After spending a year or so on it, I got busy with other things (books, etc.) So I haven't polished or idiot-proofed it. Nor have I been keeping up with the latest NIPs. I find it useful; and it is my primary window into Nostr; although I make use of Damus on the iPhone from time to time.

quoting nevent1q…fmsl
The theory of operation of more-speech is:

1. Relays are categorized as trust, web-of-trust, or all.
* trust: Only events from those who are trusted (kind 3) are subscribed.
* web-of-trust: Only events from those who are trusted, and those whom they trust are subscribed.
* All: Every event is subscribed.

Users make this choice based upon the volume of the relay. A very high volume relay will have to be constrained to just 'trust'. Moderate volume relays can be relaxed to 'web-of-trust'. Lower volume relays can be set to 'all'.

2. Every event is subject to a set of filters associated with tabs on the display. The filters within a tab can select or block based upon the ids of users, events, or the content of events. So, for example, I can set up a tab that will select for all events mentioning GAZA while also blocking certain nasty people based on their ids. I can also set up a tab that selects for any event sent as a reply to a particular event id -- thus capturing the thread of an event.
