The US and USSR collectively had 25 lunar mission failures (not counting successful flybys, orbiters and impactors) before Luna 9 was successfully soft-landed on the moon [1].

India's first attempt at an orbiter was successful, and their first lander mission failed only due to a software issue. I don't think there's enough data yet to say that they "find it hard" compared to the Soviets.

Disappointing, given the evidence that "natural" immunity has been shown to be less effective at producing neutralizing antibodies than many of the vaccines that are available[1]

ping "Hey, Bob, can I share my desktop and show you something?" Five minutes later, Bob is fixing his mistake. Or, Bob has notifications turned off, and he lets me know as soon as he's available again.

My point is that the tools are there to address this concern. I don't go a day without sharing my desktop or looking at someone else's. And in some ways it's even more efficient and less disruptive than getting up, walking over to someone's desk.

Tom Mahood wrote some interesting well-researched posts about the possibility that alleged "UFOs" seen over area 51 may have been the result of proton beam testing.

This is a good starting point [0]. The page also links to several later updates.

According to a 2017 report by the Airline Owners and Pilots Association (AOPA) [1], general aviation -- defined as all civilian flying except scheduled passenger airline service -- consumed 209 million gallons of avgas and 1.8 billion gallons of jet fuel.

NB: turboprop aircraft also consume jet fuel.

> they just ran & ran.

Until they didn't, usually right in the middle of a tape-out.

Nice to see this site is still around, though!

Yes.

> independent of property value

I think the word "value" is mis-used here. The potential sale price of my home has no value at all to me unless and until I decide to sell.

I pay taxes on my home based on the price I paid for it -- based on what I can afford. Neighbors coming in and paying 2x that for their houses will not change what I can afford. Is it right that my taxes should go up because of their wealth? It's not unlike changing the terms of a contract after I've signed it.

And should I decide to sell, the buyers will pay taxes based on the new sale price -- based on what _they_ can afford. This seems eminently more just than people being forced to sell due to rising taxes simply because their new neighbors can afford to pay more.

Last May investigators at Sportradar, who spend most of their time identifying match-fixing, conducted a pilot scheme at two exhibition tennis tournaments where they tracked down trolls.

Those targeted included Taylor Townsend, who was abused by six trolls because of her skin colour, and a male tennis star who was threatened with physical violence against himself and his girlfriend. In total 44 people sent abusive messages to players during those weeks. Sportradar tracked down 21 of them.

They then alerted the appropriate authorities and helped them pursue an appropriate course of action – from kicking the trolls off social media platforms to working with law enforcement to bring legal proceedings. Of course the response was different depending on the severity of the threat and location. But it helped the victims feel as if someone was watching their backs.

Imagining that the Ingenuity team is grinning right now: "You need wind to blow off the dust? We got this."

Haven't thought of this in a while....

One of the demo sounds shipped with SunOS was a little metallic "ding" which, if repeated fast enough, would sound just like a cooling fan with a loose bearing. When my co-worker across the way complained about a noise from his machine I told him to hit it on the side; he did, and of course the sound "stopped".

Might have been several days later when I got busted from laughing when hitting his workstation as hard as he could didn't "fix" it anymore. I have no idea how that hard disk survived.

EDA is "Exploratory Data Analysis" ?

I mean, I see Electronic Design Automation when I see EDA, and pretty sure it's not that.

Oh, so that's what this was about...

Someone asked a tangential question on another thread and I thought, Oh! There was an Omega Tau episode on that very subject! It's been about five years since the link was posted to HN, so it's about time to revisit it.

Roughly half the episodes are in German and half in English.

Here's an excerpt from their "About" page

> How do scientists uncover phenomena and explain their connections? How do engineers design machines, methods and infrastructure? At omega tau, experts give detailed answers. Over the last ten years, we have produced 300 episodes in which we dug deeper, until we ran out of questions. Join us on our journey through the world of science and engineering: the closer you look and listen, the more interesting things get.

There was a very interesting Omega Tau podcast about this very subject a while back. They go into a lot of detail about the optimization problem and how they address it.

Had he started later in the day, Piet Hein might have written,

  There's an art of knowing when
  Never try to guess
  Cook until it's soft and then
  Ninety seconds less

Came here to post the same thing (and it was pretty much the same parts!) Our standing Fry's joke was about how one side of the aisle had chips, but the other side had chips. I haven't been there since early 90's, though, so at least it remains as it once was in memory (of questionable density at this point).

I think that's reading too much into it. One can care about meeting their responsibilities because they love their family. And "being a great parent and partner" can be one of those responsibilities.

Well I guess I'm one of today's lucky 10,000 and grateful to have discovered him through the article.

Reminds me of the story of the pilot who is being nagged repeatedly to expedite descent by ATC. "Don't you have speed brakes?" says the ATCO with exasperation. "Yes" comes the reply "But those are for my mistakes not yours."

> though for some reason we haven't made a lot of progress

The risk that reprocessing can produce weapons-grade plutonium has been one reason. [1] Frustrating not only because it makes it unavailable as an energy source, but, as I understand it, the waste products from fast breeder reactors generally have much shorter half-lives than the current waste.

Can you elaborate on what you mean by "stochastic forms"? The meaning and usage of the word that I am familiar with don't seem to fit here, so I don't think I'm getting your meaning. Thanks

It's marketed as "Inverter Technology"

Most of the major brands in the US have them, now, and the reliability is improving. As I understand it the drive transistors in early models were prone to failure.

Great news for MS, but doesn't myelin also play an important role in learning in general? If a safer drug can be found I wonder what role this could play in treating some intellectual disabilities? Or, if one tends toward a more dystopian outlook, a role in widening the gap between the "haves" and "have-nots".

Is the "Twitter PWA" something other than "www daht twitter dot calm" in a web browser?

No. If someone makes the claim, "X is important", it's perfectly reasonable to ask them to substantiate that claim.

Phase 3 from another perspective:

The correct answer is "2+2 is 4"

Your score: 0/1

Did you mean 28E12?

That number is meaningless without context. USGS estimates the earth has about 24 quadrillion metric tons[1] of ice, so, unless I'm doing the math wrong, this loss represents 0.1% over 30 years.
