Briefly: if you expect 10 failures in 10 years evenly distributed then you would expect 1 per year.

If it is a Possion distribution then you'd expect them to bunch up and get years with none, then them concentrated over a few years.

Possion distributions usually imply a time factor. That's concerning in this case as it implies maintenance isn't effective.

You like Issac Asimov, XML, and shoes with toes. ... You type in Dvorak.

That's science fiction with no grounding in reality. You may as well be going on about transporters and transparent aluminium.

Every time a Moon mission comes up, Helium 3 gets trotted out, but it's just absurd.

For one, billions of tons of rock would have to be mined to extract any reasonable amount of Helium 3. Even with heavy machinery and robotic miners operating 24/7, this is a stretch.

But much more importantly, Helium 3 is utterly useless. It was proposed as one possible fusion fuel but then a much cheaper alternative was developed almost immediately: breeding the required fuel from a blanket of Lithium.

Last, but not least: There are exactly zero fusion power plant operational on Earth right now. There will be exactly zero commercial fusion power plants operational on Earth for at least a decade, no matter what new technologies are developed. At the current pace, according to current plans (e.g.: ITER/DEMO), there will be one (1) power plant generating a trivial amount of power staring in 2048. Likely well into the 2050s there won't be many more.

So to summarise mining lunar He3: We should spend trillions of dollars digging up the Moon for power plants that won't exist for three decades and don't need need the helium anyway.

Well, progressive originally meant marching forward, making progress [1]. As such it is literally the opposite of conservative, which means "disposed to retain and maintain what is established, opposed to innovation and change," or, in a negative sense, "opposed to progress" [2].

[1] from Etymology Online (!ety on DDG): "characterized by advancement, going forward, moving onward" (in action, character, etc.), from progress (n.) + -ive, or else from French progressif, from past participle stem of Latin progredi. From the notion of "using one's efforts toward advancement or improvement" comes the meaning "characterized by striving for change and innovation, avant-garde, liberal" (in arts, etc.), from 1908; of jazz, from 1947.
In the socio-political sense "favoring reform; radically liberal" it emerged in various British contexts from the 1880s; in the U.S. it was given to a movement active in the 1890s and a generation thereafter, the name being taken again from time to time, most recently by some more liberal Democrats and other social activists, by c. 2000.

They explode because chemical sources of electricity inherently seem to come with risks, and these are reactive chemicals with high energy density no matter if heat or electricity. They grow crystals as they age. They can puncture membranes.

Dell probably paid a battery disposal levy to sell the device. More recent devices in Australia have to declare on this.

Personally, I think this sucks but it'd be either clunky devices or shorter life or more expensive or, my preference, less planned obsolescence. That demands process, industry costs like shared battery designs, business to swap and replace. We have some, not a lot of that.

I hoard old tech. This is my nightmare up on the 9th floor. I need to dispose of some laptop batteries.

Show HN: Free Hero Mesh: first version ready for public testing is now available
The first version of Free Hero Mesh which is ready for public testing is now available. It is far from being complete, although it is believed to be the minimum needed that someone can try it now.

It is available in a Fossil repository; there are two sources:

* Main: http://zzo38computer.org/fossil/heromesh.ui

* Mirror: http://chiselapp.com/user/zzo38/repository/freeheromesh

(The mirror is not updated as often as the main repository; also, you cannot post bug reports on the mirror, although once changes are pushed to the mirror, any bug reports posted on the main repository will also appear on the mirror, too.)

(A git-fast-export file is available upon request.)

This software requires SDL1 (or a compatibility layer, although I have not tested the compatibility layer), SQLite, and a C compiler that supports C89 with GNU extensions.

If you wish to modify the instruction set or resource set, then Node.js is also required in order to recompile them; if you are not modifying it then this is not required.

Please post questions, comments, and complaints on the NNTP (preferred) or on this Hacker News item. Bug reports may be posted either on here, or on the NNTP, or on the Fossil repository.
All US TV “news” is intolerable garbage, but since the US is the global cultural hegemon, plenty of foreign media outlets cover our news. Almost any well-respected European broadcaster is a better source for US political news than any in the country.

Newspapers are better than TV: the New York Times and Wall Street Journal are both much less sensational than any of the broadcasters.
Yes, but you don't need to use chemical propulsion for 100% of the needed energy -- just a well-timed and well-aimed change in angle to slingshot it off of a gravity well.
Well enough.

https://en.wikipedia.org/wiki/Gimli_Glider

> In 10 nautical miles (19 km; 12 mi) the aircraft lost 5,000 feet (1,500 m), giving a glide ratio of approximately 12:1 (dedicated glider planes reach ratios of 50:1 to 70:1).

Interesting. It makes sense to do something like that.
I Im not sure that the mirror has to be at the same temperature as a heat source.
The area of a dyson sphere at earths orbit would be 2.810^23 m^2
The area of the sun is 610^18 m^2.

This is where my understanding of optics and reflections breaks down. How much heat/kinetic energy is transferred to a mirror when it reflects a photon?

From a heat transfer perspective. the dyson sphere has 100,000X the surface area of the sun to radiate heat and 1/100,000 the photon flux hitting it's surface. Based on this I would expect it to be cooler.
I was tempted to see if the Donation links actually worked...
Usually the goal of having source of anything outside Earth is to use it to build (spacecraft, stations, etc.), not to bring it to Earth.

The Moon gravity well is weak but still significant.

On the other hand you could catch an asteroid and bring it back to Earth orbit and exploit it here or even completely remotely, by automated means.
I found a video of modern quartz crystal manufacturing. It doesn't have explanation, so it's basically fancy high-tech machines doing mysterious things: https://www.youtube.com/watch?v=Own-5Qz_vSs

It's interesting to compare the scale. In 1943 they were packing a box with a few dozen crystals, while the modern manufacturer fits probably 18,000 tiny surface-mount crystals in a box.

Sorry to say this, but HN is a problem as well.

I’m looking for that 1% of the posts that interest me, and when I find them it’s fantastic, since it’s info I would not be able to find anywhere else. But going through the other 99% is a waste of time.

These two combined have a harmful effect on me. I don’t know if there’s a name for it, but it’s the same as the one causing addiction in gambling/bets/games. Gathering energy/motivation to do something productive instead takes effort.

It lives on as OpenWatcom. It’s fun to think that with a DOS extender, you can write pretty much anything that does not need to be 64-bit, and it will run under (Free)DOS (which by today’s standards is almost bare metal)!
The co-op I frequent in Vermont provides milk in glass bottles from various dairies. The bottles have significant deposits, but the most is $2. You return the bottle. You get the deposit back. They clean and reuse the same bottle, as is shown by the accumulating scratches on the outsides of the bottles. The co-op is the main grocery store in town, so not "boutique" except insomuch as Vermont itself is boutique. But then "boutique" just means not typical. Your implication is that it means supported by bougie people living in a fantasy land. Most of US material culture is crap. This is not by necessity.
They're talking about living inside an asteroid that has been moved to the lunar gateway. You can imagine a looped track dug inside, to provide simulated gravity. I don't think that's very feasible, I prefer the "Islands in space" idea from Gerard O'Neill. To provide artificial gravity.

Our family gets its milk direct from a farm this way in upstate NY.

It costs about 50% more, but the quality of the milk is unbelievable and unlike most supermarket milk, we’re paying the producer a sustainable rate that yields them a profit.

Overall in New York, 75% of remaining dairy farmers will be bankrupt in a year or two.
I seemed to have trouble with sodium lauryl sulfate (SLS).

Sleeping on freshly washed sheets would irritate my skin.

I switched to a detergent without SLS and they were soft and comfortable again. I also did the same with shampoo and toothpaste, to my benefit.

Thing is, it's a cheap ingredient that has been signed-off by regulators. But manufacturers are onto the controversy and just use "alternate" names for it on the ingredients list.
If you postulate a still non-existent fusion reactor, and then postulate an enormous industrial lunar mining program- 150 tons of lunar regolith gets you 1 gram of He3- this might, might, might work out. Most people who crunch the numbers think that this will never be sufficient in and of itself to justify a lunar program, it only makes economic sense if it can piggyback on top of a program that exists for other reasons.

If you want helium3, seawater is probably a better source than the moon. The difference between 150 tons of lunar rock and something like five times that of seawater is probably a wash, even ignoring the expense of gravity wells.
Lunar gateway is a first space station that will not be orbiting Earth. While current approach is inefficient, I assure you the challenge of building, launching, and operating such a craft will definitely push overall space capabilities further.

Ha! I lived in a small town in WI, and LSD was more available than any drug. Not only available, but available in exotic forms: microdots, gel tabs, fancy printed blotter. Sometimes I wonder if it was a government experiment, that's how remarkably available it was relative to other drugs. Consider for a moment it is pretty easy to grow mushrooms or pot, and then consider that a bunch of small-town kids in WI had easier access to a difficult-to-synthesize psychedelic. Wild.
My plan to minimize ageism is straight forward. Continuous improvement in latest tech stack. Demonstrate delivering solutions. Regularly interview with recruiters for positions at or above my level.

When the full time offers slows down, I’ll take on vendor and contract positions. When the contract positions slow down, I’ll start my own vendor or consulting company. I’ll hire younger sales and product people to be the face of the company.

I always look for solutions to problems, implement the solutions and make adjustments when needed. This is the kind of solution oriented mindset that helps get offers and land clients.

There are so many software engineering problems and so few people that can deliver the solutions. There’s no real competition, younger or older. There are enough to go around for everyone.

Good luck to you.
Maybe it would be good to mention what this project is at the top of this post. What is "Free Hero Mesh"? A mesh network framework? A 3D mesh generator? Something to do with textiles?

Random = clusters happen.

In fact, mathematicians were hired during the Battle of England to estimate whether the Germans were aiming for specific buildings (“why is there a cluster of bombs around this church???” or around some secret offices) or just spreading randomly. Verdict: They weren’t aiming, it was random chance that bombs made some clusters onto some buildings. This is what random looks like: No even distribution, sometimes you get a cluster which looks like a series.
This is a fantastic effort! Kudos :-)

Not an AVer, but there are many studies on the ill-effects of adjuvants in vaccines. The industry has also had its fair share of SNAFUs. There is a reason for the 1986 vaccine law.

Both those articles on DPoS are referring to master node type coins. Nano's model is different in a couple fundamental ways:

> Block producers are those responsible for creating and signing new blocks. They are limited in number, and are elected by the voters.

Nano uses block lattice so there aren't a limited amount of block producers, every account produces its own blocks on it's own blockchain.

> Because the delegate rewards in EOS are now so high (5% annual inflation, about $400m per year),

Nano has zero rewards to run representative nodes, this is important to avoid emergent centralization https://medium.com/@clemahieu/emergent-centralization-due-to...

If anyone reading has access to versions 9, 9.01, or 9.5B, I'd really appreciate you getting in touch here or using the info in my profile. I want the version of the compiler that was used to build the original Doom, which shipped in 1993 and was patched in 1994/1995.

In addition to this archive.org bundle, versions 7.0, 8.5a and 9.5 are floating around. Looking at compiler output for standard library functions, it seems DOOM.EXE was compiled with one of the in-between versions.
Cooling tower "drift" is an air emissions PM2.5 permit matter in California. What is drift / carryover of the unsaturated and saturated material? Typically it happens associated with entrained water droplets; that's why e.g. salt water can't be used (among other reasons). More to the point, what fraction of the total capture energy are you eliminating? If you're changing evaporative efficiency in a forced-draft tower, you're incurring additional fan power or worse, increased fuel use in the process for which cooling is taking place. How do those balance against the fan power of a separate capture unit? But maybe the biggest matter: in other capture technologies, the heat of dissociation/regeneration and the compressor power to deliver to sequestration are very large. What change to the total energy budget are you proposing? When you're at scale, what fraction of total capture needed could be delivered this way?

Does putting CO2 in a bottle keep any CO2 out of the air for as long as a month? Removal times of hundreds of years are required for the capture process to contribute to climate.
on the one hand, this is clearly a 2D simplification of a 3D problem.

on the other... if you imagine your spiral as projecting outward a non-infinite distance, how could it possibly "trap" air? the air would flow toward (and away from) the viewing plane very quickly.
I would love to see that Incorporated into a 2 M transceiver because I'm not aware of any commercial Ham radios that natively send text (yet).

But during emergency nets some of us use Fldigi (short for Fast light digital), a free and open-source program which allows an ordinary computer's sound card to be used as a simple two-way data modem.

The software is mostly used by amateur radio operators who connect the microphone and headphone connections of an amateur radio SSB transceiver or an FM two way radio to the computer's headphone and microphone connections, respectively.

https://en.wikipedia.org/wiki/Fldigi

It can be difficult for some to get set up and properly configured, but once it's working, it will transmit text messages without major errors under the noise floor, i.e. can barely hear it because of all the white noise.

It does cause complaint's when used on voice simplex frequencies and repeaters.

It sounds worse than packet radio https://en.wikipedia.org/wiki/Packet_radio which I kind of like hearing.
IIUC, this says there are nuclear excitation states that can be selectively and controllably pumped with X-rays. Any chance of creating a population inversion for lasing action? (Or whatever it would be called at nuclear energies/wavelengths?)
