How close will this be to being able to resolve starspots on something other than our sun?

Get a 3M respirator with the appropriate filters for handling lead. When finished, wash up with Hygenall Lead-Off.

That's not hard to imagine. Quick, what's 1/3 of a meter? The sometimes problem with metric is it's base-10. The prime factors of 10 are 2 and 5. Feet are in base-12, which has the…

Probably all of it.

I believe you are under a mistaken assumption. It's never ok to kill the suspect. Still, one can be justified in using lethal force. It's a very subtle distinction. You never shoot…

Are the police not able to run away? No, not really. To threaten somebody with deadly force is a felony. You or I would have a duty to run away if possible. A police officer has a …

Websites are like salespeople and the police: they can and will use your data against you. The first time I was told about Strava, I immediately dismissed it as useless. (After all…

If you are unprepared for a meeting, who's fault is that? There are different kinds of meetings. You need know what kind one is before you agree to attend. If it's a decision meeti…

The fix isn't quite right. It may technically produce correct output now , but it's sloppy. The sloppy code is brittle and dangerous and perfect food for bugs, but that's a minor p…

Should hackers actually kill somebody, I struggle to find a reason why the relevant automotive engineers and their managers shouldn't be charged and convicted of negligent homicide…

Or, perhaps planets able to support civilization are relatively rare, and the few civilizations dumb enough to loudly broadcast their presence soon get exterminated when their plan…

Intentionally or not, the author has cherry-picked the data in a way that completely undermines the article. The conclusion that "lives are at stake" is obviously true and supporte…

This is a conversation with Andy Weir about Elon Musk, among other topics.

I don't understand the purpose of these extreme licenses. If you don't want to restrict the usage of your software in any way, why not place it in the public domain? As I understan…

> O(length of string) per step The big win here is not that it's as fast as the optimal algorithm (it's not), but that it's nearly as fast and vastly simpler. You're technically ri…

Even if a MITM can intercept HTTP requests to your server, they still can't hijack your registration attempt. The real problem is that if somebody can intercept your HTTP traffic, …
