If it's true that one can evaluate the performance of a programmer, what does that mean? Can it be reduced to a vector of scalar values?

I hate doing performance reviews, and I especially didn't like when at a former employer I was asked to stack rank programmers. I feel like it's a task that's so difficult to get right, I can't even think of a wrong way to do it that's useful.

> Vue is the only one of the most popular 3 frameworks that can

I don't know if you intended it this way, but the start of this comment makes it automatically flamebait.

Discussion around release announcements can quickly turn into a flame war. Please use caution.

> Most transmission is person-to-person, there isn't a ton of person-to-surface-to-person spread

So I've heard. Doesn't this mean that the UV news is of little impact?

I've never had an AOL email but you just inspired me to sign up for one.

If a domain is unavailable, does the query on namecheap still go to third parties? Is it possible for third parties to snap up an available domain they know has just been queried?

Yeah. I'm concerned that a malicious actor might MITM their site and serve content that's less funny.

I haven't started recording phone calls with companies yet, but when I started thinking about it, I heard "This call may be recorded for quality purposes" as giving me permission to record for quality purposes.

Question for history buffs: What are some instances where you'd say, "Gee, I'm glad Presidential pardon was available"?

Employers drive that phenomenon. They want teenagers available for work earlier in the afternoon.

I think of Montessori as a smart middle ground between under-structured "child-centered" and over-structured traditional education. I've seen it explained as a triangle of child, teacher, environment, where the teacher spends some time preparing the environment, some time instructing the child how to interact with the environment, and some time making adjustments to the environment.

Blue light bounces around the sky a lot so we see it in all directions. At sunset, when we look at the horizon, we see light that traveled through a lot of sky without bouncing away, so it's less blue.

Who's Rayleigh?

From the article:

This work is an attempt to capture the “whole system costs” of an individual power plant. This could include the costs of enhancing the electricity network to connect a new power station, balancing supply and demand in real time, and providing backup power during periods of low wind or sun.

From the comment I'm replying to:

I wish proponents renewables were honest enough to not withhold these problems

As the article makes clear, nobody is hiding from the fact that there are costs associated with providing backup power during periods of low wind or sun.

The other problems in the comment are not problems with renewables per se (aside from one problem with the straw man "100% renewables"), but problems with German government policy.

Is there no link to the post apart from the top-level link to the blog?

That's not for sure. Low interest rates drive prices up or prop prices up. To find the ideal time to buy you have to know the future: if rates are higher than they're going to be, you can buy at a lower price now and then refinance when rates drop. Of course, knowing if/when rates are going to drop is the hard part.

If I could reduce the spread of a disease by starting my professional emails with "Heyyyyyyyy" I totally would.

Yes, this. Lighthouses are another good example.

>This is an extreme example (because it's so exceptionally pretty)

For a more pedestrian example, search for images of "letchworth state park upper falls". Note that photographers rarely try to crop out the railroad trestle even though it's much less pretty than everything else in the picture. It's an accepted part of the landscape and the aesthetic.

> An inhalation valve does less to protect other people, because the expelled air still has to go somewhere, and will just blow out of the sides of the mask. It could theoretically go through the mask material if it was thin enough, but there’s probably too much pressure inside and it’ll burst out the sides

No, an inhalation valve makes 0.0% difference here. Here's a simple mental exercise to understand better. Imagine two people side by side. They are wearing identical masks, except one has an inhalation valve. They breathe in, pause, breathe out. In your mind, freeze the frame at the pause between breathing in and breathing out. At that moment, what's the difference between the two? Nothing. Now watch them breathe out. What's the difference? Still nothing.

Maybe you all can agree that insurance and lottery are the same in that only a fraction of consumers come out ahead, and are opposites in terms of smart vs. stupid.

I think a link to your MUD would be on topic in this thread.

You answered your own question.

> Where is this coming from that only a small amount of protection is provided to wearer [...] public health authorities

I clicked the HN link to your comments. I couldn't quickly find studies, just a mention of Korea having success with KN94 masks. I think it's safe to repost them now without being repetitive.

Your comment assumes the entire purpose of a (nearly) sealed mask is to protect the wearer from incoming droplets or particles. I don't understand where this ignorance comes from; it's been widely known and repeated for some time that masks do much more to protect others from infection from the wearer. There's only a small amount of protection for the wearer from infection from others.

An inhalation valve preserves the mask's primary purpose by closing off during exhalation. It gives up a small amount of protection for the wearer, but obviously a lot of people aren't interested in that anyway and refuse to wear masks. With an inhalation valve they could at least protect others.

> The lost protection against inbound particles isn't much...

Why would it not be impacted? You'd be breathing in unfiltered air, and that's the main method of transmission.

It would be impacted. You'd lose 100% of that benefit. But 100% is still not much.

> Cloth and non-medical disposable masks are not considered protective

> anti-maskers threw enough of a fit about fairly comfortable ones

How's this for a solution? Make masks with inhalation valves. You can find masks for dusty work with exhalation valves. It wouldn't be too big a change to reverse those valves. The lost protection against inbound particles isn't much, and the gain would be near elimination of the inherent discomfort of re-breathing CO2. I'm not an anti-masker, but I notice I'm a lot more comfortable with my mask off.

When I saw the first statistic was US only I assumed the WWII statistic was also US only. Nonetheless, JoshuaDavid made a great speech. Favorited.

Are taxes only for things that are bad for the rest of us?

Perhaps the core question is, "do billionaires owe a larger portion of their success to society at large than regular people do?"

My twitter client shows a reply from him yesterday, mentioning you, that points to an NPR link, which in turn cites this article: https://www.france24.com/en/20150808-france-wealthy-flee-hig...

Does it distinguish between dev dependencies and runtime dependencies?

Setting noImplicitAny should be adequate to address that. Java is getting type inference soon too.

TypeScript is the obvious choice for an experienced webdev. It's worth spending extensive time on to get good. Learn generics and advanced types to the point of not needing to look things up.

Then what's the section on "Threads" about in https://www.gnu.org/savannah-checkouts/gnu/emacs/news/NEWS.2... ?

Threads

* New variable 'main-thread' holds Emacs's main thread. This is handy in Lisp programs that run on a non-main thread and want to signal the main thread, e.g., when they encounter an error.

* 'thread-join' now returns the result of the finished thread.

* 'thread-signal' does not propagate errors to the main thread. Instead, error messages are just printed in the main thread.

* 'thread-alive-p' is now obsolete, use 'thread-live-p' instead.

* New command 'list-threads' shows Lisp threads. See the current list of live threads in a tabulated-list buffer which automatically updates. In the buffer, you can use 's q' or 's e' to signal a thread with quit or error respectively, or get a snapshot backtrace with 'b'.
