The sponge also converted 20 percent of the incoming sunlight to steam. ... The researchers’ current design builds on a solar-absorbing structure they developed in 2014 ... that was able to boil water to 100 C and convert 85 percent of the

That's not a ridiculous question. It's a perfectly reasonable thing to ask. Most likely, the answer to your question is no. The reason is that without having some randomness to begin with, even rounding errors are deterministic: y

It's harder to tell how long an ebook is than a paper book and harder to know where you are in it from the feeling of how many pages are gripped in each hand. This is a downside of ebooks for me--harder to get an automatic sense of the

who gets to be laid off first, the CEO or the developer? Wrong comparison. The CEO and developer are both employees. I've outlasted laid-off CEOs at several places of employment. The comparison is between an employee and an owner .

It is an investment from a managerial accounting perspective (how the business really works), no matter what it's called by financial/tax accounting (how the business formally reports its status). Expenses, such as taxes or th

Why would you not want to be (practice as) an MD, but would be willing to consider being a PA, especially when the much higher cost of becoming an MD (time, effort, money) isn't even a factor for you (you already paid and won't

Sure, ask Matz (the Mormon creator of Ruby) how closely he's related to his wife. I hear Japan is pretty insular.

No profit means no value creation, the company is doing nothing. This part isn't true. If you take inputs and combine them into something the market values more than the uncombined inputs, the process of combining them creates value,

A VERY timely article for me. About a month ago here in Silicon Valley, I noticed that a crow had been violently torn apart and the pieces scattered all over my backyard lawn. I assume the killer was a raccoon--another improbably intelligen

And this error is ironically an illustration of the exact problem he was commenting on: our brains tend to work by association, and implication (A implies B) tends to be interpreted as association (A implies B means A and B are associated,

So true. One of the worst aspects of school is the imposition of a uniform schedule on everyone. There is a point beyond which learning faster means learning more shallowly. You don't have time to develop a rich mental model, which you

I recommend skipping both cases of the letter O as well. I'm surprised so many people use it, especially to mean "object". Really, code that uses `my_dict[O]` where the object is a hashmap key or `O1 + O2` demonstrating the w

Honest question, how is anyone expected to keep up with all of this? That is a good, honest question, but there is a different standard of expectations for some random programmer doing a project and one of the biggest, most powerful multi

It seems to me that one thing we could do would be to use some updated version of our existing technologies to provide people with personalized notifications of such things as what station they're entering via personal technologies suc

Well, nothing describes how "all science works", but ideally you don't revise your model based on new data. Instead, you take all of the data you have, both old and new, start over from scratch and try to find the simplest mo

Even the name tells you that C++ was originally designed to be C with extra features. It can still be used that way and frequently is. These days, there are contexts in which the differences are very significant, and there are many others w

Is there a roadmap for what is currently planned for the standard library? A lot of language choice these days comes down to what high-quality batteries are included and what will require either trusting some unknown 3rd party's github

Apple has been hiring AI people for a while, and there is a possibility that the openness of the rest of the world (academia, open source, other big companies working with academics and open sourcers) will diffuse AI discoveries fast enough

There are old, but still good and sometimes best, learning materials for all mainstream languages. That creates a challenge for learners, because learners should be focusing on the future of the language, not its past. If you're learni

That would make me pretty nervous. A couple of years from now, it will be taken for granted that all new Python projects are written in Python 3, and AWS Lambda will either be obsoleted by a Python 3-based competitor or--about the time you

Both claims are correct, as is common with statistics. If you write `print "hello"`, you just increased the QUANTITY OF PYTHON 2 CODE. If there is one guy left in the world who occasionally writes some Python 2--and even if he&#x2

Really, just learn to use callbacks properly. Well, wait, actually, you should skip that and start getting used to using promises instead--a big improvement. Well, I mean, until next version is ready, and we can start using async/await

It drives me crazy that I can't find half of the labels I'm looking for, and when I do, I can't increase the size of the labels enough to make them readable. Frequently I'll have to fight with the map, zoom in and out an

Yes, the lack of a built-in project switcher is a nuisance. I'd like to have a little dropdown at the top of the (left) sidebar with project names. A keyboard shortcut plus a bit of fuzzy matching drops down the list and picks a projec
