Comment Re:Fuck Lockheed (Score 1) 108

Nobody is going to increase their expenses voluntarily. Especially on something like a rocket, where local disasters are very public and very expensive. And doubly not in a situation where increasing the cost of the contract would be a political nightmare likely solved by the contract moving to someone else buying from Russia.

When money talks, nobody asks questions.

It's what you get in a market economy. Sorry, but outsourcing is cheaper and the cheaper product will win over the better product 99 times out of 100. Especially when it comes to government, where they're legally obliged to go with the cheapest bid.

That's just the way the country is set up. Anyone with a brain would tell you that outsourcing even across State lines, never mind international boundaries, carries political risk. The nation decided, rightly or wrongly, that saving money was more important. If the roll of the dice is against you, well, too bad. That happens.

It also carries geological risks. Putting all the chip factories in one earthquake-prone zone in Asia - and, indeed, along the same bloody faultline, was a marvelous piece of risk management. Penny wise, pound foolish, as us Brits usually say. After the fact and rarely before.

That brings me to the related point of putting vital infrastructure in dangerous locations.

Silicon Valley (a highly polluted zone that exports contaminated water at vast expense to places that dump the water back into Silicon Valley's water sources) is a remarkable piece of stupidity, being as it is, situated on one fault line and close enough to another. Silicon Forest (Oregon/Washington State) has taken up some of the IT load, but given that the locations are still on the Ring of Fire and thus still in dangerously unstable territory, the industry has successfully doubled the chances of catastrophe.

Most of the design engineers not located in these places are in India (a nice, stable location with no deadly diseases rampaging through the countryside and no risk of religious civil war or war with any neighbouring country), Israel (ditto except for the disease AFAIK), China (great choice, no problems there!) and Jaan (not the least bit likely to get into a conflict with neighbours, have power stations explode, suffer earthquakes or tsunamis, or lunatic politicians hell-bent on causing a crisis).

DO NOT BOTHER WITH REFRACTORS!

(Yes, that was intentionally shouted. If anyone actually needs to be told that, they're not to be trusted with gentleness.)

Refractors will always produce low-quality images. A good pair of binoculars will cost less and show you more. Seriously. Refractors are for the gullible. Powerful binoculars will not only be cheaper, they will collect more light, they will be far more rugged, they will be easier to align, and they will be easier for kids to look through.

Comment Interesting question (Score 1) 187

Reflectors with an effective collecting area under 4" are worthless. That's everything from the aperture to mirror. That's going to put you well over $50. Adequate reflectors don't exist under $250, except on special clearance.

You are better off buying a remotely controllable reflector with a webcam fitted to the eyepiece and having a group of kids take turns steering it. Firstly, it's cheaper overall. Secondly, you don't have breakages to worry about. Third, kids prefer nice, warm rooms to freezing pitch-black country parks well away from light pollution, hot drinks, facilities, ...

Not only is this more likely to be attractive to kids, parents who invest $50 in a group effort are much more likely to make sure they get their money's worth than if they spent the same amount just on their kid. It's all about the attitude of not wanting to pay for someone else's stuff. It's a vulgar, uncouth attitude, but that makes it easily exploitable for everyone's gain.

Comment Meh. James Lovelock's idea is better. (Score 2) 80

It's a very simple, even lower-tech approach. Unstable molecules are unstable, stable ones aren't. Life isn't capable of producing stable molecules from stable molecules. Something, somewhere down the line, therefore must produce unstable molecules.

If you use spectrometry and find a planet that has two or more highly reactive molecules (especially if they cannot coexist naturally), that planet has complex life. If you have one reactive molecule that breaks down in sunlight but is being refreshed, that planet must have at least simple life. If the planet has highly reactive molecules that don't readily form naturally, you have life that is nominally intelligent.

No requirement for any technology capable of generating a specific signature. No requirement for the absence of metamaterials. No requirement for a telescope big enough to detect the signature against natural variation.

SKA would be capable of detecting an alien civilization using Lovelock's method anywhere inside of 1,000 light years, given the size and sensitivity currently being proposed. How big would the James Webb telescope need to be to get an IR signature on the industrialized part of the US at that range?

Found a bug in physics.c, those cars we mass produced last year will spontaneously explode after 367 days of exposure to an atmosphere containing oxygen, or when white lines are painted rather than vinyl, or when attempting a corner of a prime number of degrees when speeding on a cambered road.

Why wasn't this spotted sooner?

Because we hadn't expected to need chemistry or non-Euclidian geometry in a physics engine.

Then make the episodes longer. Or have one set of presenters on the first show (they're usually paired) and the others on the second show. Or eliminate redundant footage so that you can have two or three times the content. Or eliminate the advertisers, sorry adverts, and get three times the running length.

Discovery got caught using fake footage in documentaries. No scientist should be working with a channel that is peddling fraudulent material. History lost a lot of reputation with their academically bogus Ancient Aliens stuff, but at least they didn't try to offer photographs and videos they themselves doctored as "evidence".

If the three have projects worth taking seriously, they won't be projects on Discovery. HBO has less of a credibility issue.

Comment Re:We get cancer because we have linear DNA (Score 1) 185

That's easy to fix. If a cell has not just the existing error correction codes but also digital ones as well, then mutagenic substances (of which there are a lot) and telemere shortening can be fixed. Well, once we've figured out how to modify the DNA in-situ. Nanotech should have that sorted soonish.

The existing error correction is neither very good nor very reliable. This is a good thing, because it allows evolution. You don't want good error correction between generations. You just want it in a single person over their lifespan, and you want it restricted so that it doesn't clash with retrotranspons and other similar mechanisms. So, basically, one whole inter-gene gap/one whole gene protected by one code. Doable. You still need cell death - intercept the signal and use a guaranteed method.

Comment Exploit that which you cannot defeat (Score 1) 185

Here, in the year Lemon Meringue, we decided to solve the problem once and for all.

Instead of trying to kill cancer, we hijack its techniques. We start by having nanocomputers in the vaccuelles of each brain cell. These keep a continuous backup copy of the state of the brain up to death. Cancers disable the hard limit on cell duplication that cannot otherwise be avoided. By using the techniques of cell-devouring microphages, the cancer "consumes" the old cells and replaces them with new ones. They can't spread anywhere else, because that's how the cancer is designed to spread. Once the body has been fully replaced, the cancer is disabled. The brain is then programmed by the nanocomputers and the remaining cells are specialized by means of chemical signal.

This does result in oddly-shaped livers and three-handed software developers, but so far this has boosted productivity.

The free market didn't provide alternatives. The free market created Microsoft and the other monopolies. Adam Smith warned against a free market.

The majority do not create alternatives, either. The majority like things to not change. The familiar will always better the superior in the marketplace.

Alternatives are created by small groups of people being disreputable, commercially unproductive and at total odds with the consumer. These alternatives will typically take 7-14 years to develop. Adoption will typically reach peak after another 7-14 years. By the 30th year after first concept, the idea will be "obvious" and its destiny an "inevitable consequence" of how things are done.

In reality, it takes exceptional courage and a total disregard for "how things are done". 7-14 years with guaranteed losses is not how the marketplace works. Even thinking along those lines is often met with derision and calls of "Socialism!" by the market. No, real inventors are the enemy of the free market.

If you want a Linux desktop, you must forgo all dreams of wealth. You must subject yourself to the abject poverty that is the lot of an inventor in a market economy, or move to somewhere that supports the real achievers.

Comment The problem isn't X. (Score 1) 727

The problem is corruption. OSDL were working on a Linux desktop environment, but a key (financial) figure in the organization worked hard to kill off success and left around the time the unit went bankrupt. Several organizations they've been linked to have either gone belly up or have suffered catastrophic failure.

I won't name names, no point. What is the point is that such people exist in the Linux community at all, parasites that destroy good engineering and good work for some personal benefit of their own.

X is not great, but it's just a specification. People have developed Postscript-based GUIs using it. It's merely an API that you can implement as you like (someone ported it to Java) and extend as you like (Sun did that all the time). The reference implementation is just that. Interoperability of just that set of functions used by Glib/Gtk and Qt would give you almost all the key software.

Alternatively, write a GUI that has a port of those three libraries. You could use Berlin as a starting point, or build off Linux framebuffers, or perhaps use SDL, or write something unique. If it supports software needing those libraries, then almost everything in actual use will be usable and almost everything written around X in the future will also be usable. If what you write is better than X, people will switch.

Binary drivers exist and are loadable so long as they are properly versioned.

Block drivers can always use FUSE.

Automatic builders can recompile a shim layer with new kernels (or even the git tree version), automatic test harnesses or a repurposed Linux Test Project can validate the shim. You don't need to validate the driver for everykernel, if it's totally isolated from the OS and worked before then it'll remain working.

Automated distributors can then place the binaries in a corporate yum/apt repository.

What has an ABI got to do with it? Only gets in the way of writing clean code.
