I may be misremembering Godel's proof or misunderstanding your last paragraph, but I thought Godel's proof actually presented a specific undecidable statement. The hope then was that somehow undecidable statements could be cordone

Interesting. I've had exactly the opposite experience. The Surfaces I've owned (3 so far, over the last 8 years) have been much more reliable than the other Windows laptops I've used over the same time period (mostly at work)

Did Apollo 8 go to the moon?

by joelshep 6mo ago
Hardly. Remembering the end of 1968, when Apollo 8 made the first manned voyage out of earth's orbit, and orbited the moon: Newsman Walter Cronkite remembers the year of Apollo 8: "The whole 1960s really culminating in 1968 were t

You can buy the Handbook of Model Rocketry and have essentially all the knowledge that's encoded in OpenRocket or RockSim. You just lack the automated simulations and the parts catalogs (whose weights and dimensions should generally be

Not true in the US either, in any meaningful way. Weight thresholds are different, FAA thresholds are different, allowed control systems are different, etc., etc.

But hopefully not that kind of interest. Model rocketry, as a hobby, enjoys a limited amount of regulation, at least in the US. In large part, that is because the community has been very good about self-policing. Most folks who are serious

I "identify" strongly as Democrat (meaning, I vote consistently, but not purely, Democrat). I've also subscribed to The Flip Side for a number of years, which will take a news story a day and present viewpoints on it from lef

This is great: thanks for sharing it. In 1983, Compute! magazine published yet another article on these opcodes: https://www.atarimagazines.com/compute/issue41/Extra_Instruc... . Now I can finally understand the w

Depends on the workload. In the past, I've worked on several workflow-based systems that performed lots of OLTP operations to drive live workflows forward, but once a workflow was done the operational data became a lot less interesting

To continue the speculation ... as a ship that size is slow to turn or halt, that seems to suggest that even if the ship hadn't suffered a power failure then it would have passed quite close to the bridge pier anyway. Was that expected

In our galaxy, or anywhere? In our galaxy, potentially 1-3 times per century but there are reasons (besides probabilities being what they are) that we humans haven't actually observed one in some time: https://phys.org/

Yes: I find "what" comments critical. Naming things is hard; getting two people to agree on the concept the name represents is harder. I write "what" comments -- usually at a class, class field and method level -- religi

If God is omnipotent, surely that would include the ability to do things that we mere mortals would construe as harmful or self-defeating, wouldn't it?

It might be obvious as far as it goes, but it's also incomplete in at least two ways. One is that as tweaks and optimizations and "supplementing the system in some way" often involves increasing its complexity, even if just a

Generally for anything other than casual viewing, the mount that the telescope rides on is generally considered most critical. You can put a modest telescope on a good quality mount and produce some great photographs, or amateur science if

In my experience, a decent refractor just does what it needs to do, without drama. There's no mirror to collimate, no mirror to flop. Once the imaging train is dialed in, you let it cool for a bit, you focus, you take pictures. It just

I think what you're paying for is minimized learning curve. If you actually want to invest the time and effort to learn the ropes, this isn't for you. If you want to go from "Whoa, look at those stars" to passable pictur
