This is not a bad tutorial for copper electroplating, using entirely found-at-home materials: https://www.instructables.com/High-Quality-Copper-Plating/ Most of the "copper electro…

Oh hey, this was me. Happy to answer questions if anyone has them :)

Eh, not so much generation as different way people think. I'm not old, have multiple laptops, desktops and smart phones. More often than not, when I need to seriously think about a…

++ Came here to post the Planet Money episode. :)

A minor note: the LightSail team says the perigee is lowering due to atmospheric drag not due to the sun slowing it down: > The perigee, or low point of its orbit, has dropped by a…

I left a reply on the OP (before seeing this), which links to NIH, CDC and a review of the subject: https://news.ycombinator.com/item?id=20511244 It's not that the symptoms don't e…

If someone wants to read some real medical texts on the subject, I would encourage them to read the following: NIH: https://www.niaid.nih.gov/diseases-conditions/chronic-lyme-d... …

"Chronic Lyme" is notoriously difficult to diagnose because there is very little evidence that it is a real illness. While there is some research on the subject, the medical commun…

Tree Style Tab is another option, allowing vertical tabs with nested hierarchy: https://addons.mozilla.org/en-US/firefox/addon/tree-style-ta... As someone that likes to use open ta…

Because enough people will believe it when they see an asteroid looming towards them on CNN, Fox, whatever. There are plenty of people that deny climate change because it's conveni…

There is a real difference between a singular event like an asteroid, and a slowly boiling frog like climate change. You can point at an asteroid and say "That thing. It's going to…

It's especially tragic because any attempt to fix the situation implicitly crushes nations that are presently bootstrapping themselves into industrialization. E.g. major "developed…

Mars is a radically different planet and has its own climate. It doesn't have anything to do with the sun getting warmer though, e.g. we can't blame the sun for the Earth warming u…

Except that, from the article, the only way to really use IPFS for pretty names is to use DNSlink and not IPNS. Because IPNS is unusably slow. So IPFS might not theoretically rely …

Yeah, folks, don't do this. Some drugs are relatively benign to quit cold turkey (a sizable percentage of people may run into irritating side effects like nausea, etc) but it won't…

I don't think this is fair for several reasons. First, cancer treatment drugs are tested heavily in-vitro first, where the only significant metric is reduction of tumor mass. Clini…

Frankly, a lot of this is the patient's fault too. The vast majority of people _do not_ want to change their lifestyle. They don't want to quit smoking, drinking, eating fried food…

> Whatever Curator does should really be part of ES itself. Just as an FYI, Index Lifecycle Management (ILM) is landing in 6.6 and provides some of the features that Curator suppor…

Agreeing here. My SO is a medical practitioner, and some of the stories I hear are just crazy. Folks who can't sleep and come in wanting meds, but after digging into their history …

Didn't down-vote (or upvote for that matter), but I think this might be glossing over some details. My understanding is that Constellation was ridiculously over-budget, behind sche…

If anyone is into Space and Politics/Policy, the Planetary Society has semi-recently started doing monthly "Space Policy Edition" episodes. Here's the most recent: http://www.plane…

Not quite the same as pure vertical farming, but greenhouse + aquaponics + high levels of automation seems to work well for certain varieties of vegetables that naturally vine. E.g…

While that's true, the OP's solution is one way to help promote thicker stems if your lighting is sub-par. E.g. more light is best, but failing that for some reason (budget, space,…

It exists! The technique is called Electron-beam lithography ( https://en.wikipedia.org/wiki/Electron-beam_lithography ), and it's exactly what you described. It's essentially an e…
