- Coworker too silent in a conference call? You can't adjust their volume.

- Want to paste some code? Hope you like smileys everywhere! (This one alone blows my mind. How is this still a thing?)

- Want to send something longer than two twitter messages? Nope, can't have that! Please chunk it into separate messages.

- You receive an image. Why does it take three clicks before you can actually see it?

- How many Skype apps would you like? There's Skype for Business, Skype (the normal windows program), Skype (the Windows app)... Knowing the nonsense that is Microsoft's account system, you probably can't even communicate between them.

- Small hiccup in your connection? Video call now stays at crappy resolution. Solution? Switch to "show full video". Or back from it (cropped). Or fiddle with other unrelated stuff and pray. It's completely erratic.

- You chose "show full video"? Enjoy doing that again in 5 minutes when Skype decides it would really rather crop that person on the side of the frame.

- Trying to edit the middle of a message before sending? Enjoy our state-of-the-art "run spell check on the main thread after every character". Now you can type your message and then watch it appear on the screen in slow-mo over the next five seconds! (Not sure if this is 100% Skype's fault, but I haven't seen it elsewhere.)

That's all I can think of on the spot.
Black pipes are great, it would make some interesting calculations to compare:

Pipes vs. PV taking heat pump characteristics into account, whose efficiency depends on climate. Installation costs, maintenance costs. The Pipes compete for real estate space against the PV, so if pipes are more efficient, does it off set the lost electricity (that would be more expensive, but cheaper than from the grid, but only when it's sunny and you can use the appliances at that time, unless you have a battery which is more capex, so does the interest/repayments on that cost get offset by using electric 24/7). Etc. Etc.

It might need some ML to figure out the best solution. And by ML I mean linear regression.
Horseshit.

Andrew Carnegie was a robber baron bastard, but it was him actually cutting checks that gave us museums and concert halls that persist to this day.

The Silicon Valley "elite" like to bitch, but they want everyone else to cut the check.
Not an expert, so take these with a grain of salt:

The core of the star is the hottest and most dense part. Greater heat and density make it easier for fusion reactions to run. If suddenly the core is made mostly of iron, then the amount of energy it produces rapidly drops. Even if there are nice, easily fusible hydrogen atoms farther out from the core, they will not be fusing at a very high rate, because the temperature and pressure is lower where they are. Also, the more easily fusible atoms remaining outside the core can't diffuse into the core fast enough to refuel it. The only possible outcome is collapse.

In some sense "dark matter" and "dark energy" are just placeholder words for "whatever thing is causing all this weird stuff to happen". This is actually very analogous to how "the ether" was a placeholder term for "whatever thing that radio waves are waves in". (Now we refer to it as "the electromagnetic field". The "ether" terminology was associated with some incorrect assumptions, such as a privileged reference frame, which is why people sometimes say it was an incorrect hypothesis. But the electromagnetic field is certainly real, it just didn't turn out to work like some people thought it did.) Scientists have observed so far the dark matter seems to behave pretty much like ordinary matter, except that it just happens to ignore the electromagnetic and strong nuclear forces. Not only does it hold galaxies together, but its gravity also bends the paths of light rays, just as we expect of anything massive. So calling it "matter" isn't too much of a stretch. It's still very mysterious, though.

Radiation pressure actually does limit the mass of stars, to something on the order of 100 to 200 solar masses, see this stack exchange question: https://astronomy.stackexchange.com/questions/328/is-there-a... That doesn't stop smaller clouds of gas from collapsing to form smaller stars, though.
<rant> Is anyone really surprised? Current culture world-wide is built on 15 second attention span idiocy and social media bs.

Want to see this go away? Remove FB/Insta/Twitter from the planet, along with the entire mainstream media, all of which have business models based on the aforementioned idiocy as well as non-stop conflict generation.

When you are done with that task go purge every sitting legislative body on the planet which in general are bought and paid for by those same special interests.

Then you'd have a clean slate to build on for intelligent dialog and meaningful efforts related to not just Covid 19, but many other pressing global concerns...</rant>
A bloaty app that's not platform native is still infinitely more usable than something which doesn't exist at all.

Electron is one of a number of technologies which allow things to exist (in a non-optimal form) that might not be economically possible if a bigger team or a lot more time were required to ship them.

IMHO the sad thing is not that Electron exists, the sad thing is that we don't have stuff that's way easier like hypercard or VB6 was.

My guess is that views here translates to hypothesis.

Sometimes Scientists could have a gut feeling, and this may not have data to back it up. I think its still important to talk about it, while acknowledging that we're discussing a hypothesis, and not a proven fact.

It's disingenuous to say it used to be worse pre-reddit because there is no data.

I will say the Reddit community is extremely toxic. I left the site about 2-3 years ago when in my opinion it got real bad.
I'll usually put the following at the top of my conf when I'm trying to get something to work, and want to test it out interactively (makes it run without forking, and log to stdout instead of a file you'd then have to tail):

Why would you need to organize your downloads folder? I just leave everything I download there until I have a reason to clear it (like low disk space, reinstalling the OS, upgrading the drive, etc.) Unless I'm down loading a file that I want to move somewhere else of course. But installers and things that get downloaded to print and all kinds of things like that just stay in the DL folder because why not.
Wuhan hit about 17% in the early days when their hospitals were overloaded. I though that was common knowledge? I also thought it was common knowledge that about 1 in 5 symptomatic cases require medical care.
Setting aside Dawkins, and looking beyond image macros, it seems to me that the meaning of 'meme', in it's common usage, can encompass the meanings of "message", "claim", "idea" and more. It's not necessarily dismissive, and can sometimes emphasize the simplicity of structure or frequency of use.
companies are not people, so this amounts to weak rights for people. the beloved constitution was about the rights of people, yet they have weak rights in practice.

I know you are kind of agreeing, but from a diff perspective.
The reason that antibodies to SARS have long lifetimes is because it is a much worse hit than COVID-19 in most cases, you can take the CFR as proof of that. Harder hit to the immune system but you survive: immunity will last longer is a good rule of thumb.

Why does my life, as someone who has made 'good decisions', matter more than someone's who has made 'bad decisions'. Especially when many of those 'bad decisions', like obesity, are products of socioeconomic environmental risk factors. This seems like a very privileged perspective which probably isn't very productive in managing a diverse society in times of crisis.
I want to say that my reddit usage will go way down, but I know that's probably not the case.

On the other hand, I know a few of the old-timers at reddit still use old.reddit, so that might help keep it alive.

In theory reddit can rebuild as an alternate front end, or someone else could do it. A good chuck of it is open source. You'd have to do a lot of work integrating the new APIs though.
But that’s why Python is much worse than Perl. The Python team was trying to move the world to 3 when it was demonstrably inferior
Can you compare `tcmalloc` to e.g. tcmalloc dynamically loaded, or jemalloc specified with Bazel's malloc option? It is unclear from the post whether the wins are improvements from the internal Google improvements to tcmalloc post-gperftools, or to reduction in overhead from bypassing the PLT

Funny, I've been slowly moving more of my activity back to Reddit for the same reason. I stay away from the bigger subs though.

Don't get me wrong, there's a lot of terrible people there but they're an easy to ignore terrible. When you read something downright asinine there it's really easy to write it off as someone who's 14 and hasn't got the life experience to realize how crazy their opinions are. When you read something asinine here it's attached to a profile that says "senior dev at company X and maintainer of open source project Y" and seeing supposedly smart people be so stupid is a lot harder to rationalize.
Every os should have a qr reader
Just was thinking, why can’t I scan a QR code that is visible on my phone or computer screen? Why wouldn’t [OS] just allow me to tap to decode any QR that is rendered on screen? This would allow QR usage everywhere, in imagery, video, etc. It massively opens up QR use cases.
Managing Big Data with Python
I'm sure they look more mature, but they might leave a bad impression. Rust already has "bad PR" with the borrow checker, so libraries being more conservative before bumping versions might work in its favour. Otherwise you might get a bad impression from the language and apparently immature libraries.
In the US, the third category is being furloughed and collecting unemployment. Here in Maryland, anyone making $55,000 or below collects as much in unemployment (with the $600/week federal supplement) than they did while employed. The IT systems have done a bad job handling some new categories of claimants (people who couldn’t collect unemployment before but were allowed to under the CARES Act). So some people are waiting for checks. But others are relatively unaffected: when the stay at home orders end, they expect to get called back to their jobs.
TIL the smithsonian removed it's Foucault pendulum in 1998 (right about when I moved away from the DC area). It was about 15 meters long and quite impressive; they had little pins setup that it would knock down, so you could look at when you arrived in the museum and see the difference when you left.
No, the answer must be false.

Since null = null is false, your case statement will return the else value. You hard coded it to be false, therefore it will return false.
sure, but the actual "on the ground" end result is Europeans get healthcare and rights at work, and Americans don't.

Yes, Europeans do have a higher quality of life, I agree.
The problem is that the word science has been robbed of its meaning. Or the meaning didn't scale well.

Every side of the so-called debate throws it left and right, now which science do you believe in? As if belief is part of the equations.

And the other issue is that there are no debates. You send a tweet, and tag WHO or some authoritative figure and then we have to believe it. Those who don't believe it are not following the science.

Edit: Science is supposed to evolve as new data comes in. Today, we stop at the first sensational news. When a fact is updated or retracted, it doesn't make the news.

I would guess you wouldn't expect to walk into a random Vienna coffee shop in the late 19th century and plot the future, either.
The model is very similar to how epoll works. The executor does not poll futures in a loop. Between polls, the executor waits for a readiness notification.

If `Future::poll` returns Pending, once it becomes ready to do more work, it notifies the executor, the executor then schedules the future to be polled again.
My roboticist opinion is that you need extremely developed AI to do what you’re saying. It requires navigational capabilities that don’t exist yet except in very open spaces like fields. Also, lightweight drones which could do these fast maneuvers aren’t very robust; you can literally slap them down with some pain. I get that even with a low success rate it could be a disaster if you have a huge amount of them deployed somewhat.
The more I learn about the US healthcare system, the more i'm sad for everyone living there.

All these loads and loads of information you need to know to go to the doctor. How can regular people ever get the healthcare they need, and we're not even talking about the vulnerable, low income, low schooled.

This. Is. Ridiculous.

I'll take socialism over this nonsense any day of the week.
We don't avoid fat - I mention in another comment about eating nuts, seeds, avocados, durian, egg fruit etc. And avoiding meat is no longer controversial in terms of health - with a little planning it's not difficult to be healthy.
There are thermal battery suppliers out there (a quick search turned up Sunamp, one I hadn't heard of before) that can be part of that kind of system. Geothermal heat exchangers as floatrock mentioned are probably the cheapest general version that use the ground as a thermal battery but don't typically have interlinked systems - and they're much more than a typical air-cooled system.

The show This Old House showed an interesting system a few years ago at [1] that used liquid loop HVAC components and thermal batteries as a tech demonstrator. There's also systems in newer high rises that have linked loops such that the hot side of the building (sun-facing) can pre-heat the heat pumps of the cold-side (shaded) portion of the building. These rely on advanced systems that don't tend to be deployed in homes (utilizing newer building management systems and newer HVAC like variable refrigerant flow to get the best efficiency).

Ultimately, things like this are expensive and uncommon so require per-site design that very few can justify because the payoff period is pretty long as you have the one-off cost of the thermal battery and often higher maintenance costs because you need someone who understands the system.

Yeah, one of the items was third party, one was Newegg. But I agree - you can't outcompete Amazon by trying to be Amazon.

Sweetwater (who I mentioned upthread) are great because they do musical instruments (and related) and nothing else. Deep domain knowledge, rich and well organized catalog, community of music nerds, and (as far as I've noticed) no third party junk.

A Newegg could theoretically do the same for computers and peripherals. (Find me all motherboards compatible with i7 and ddr4, with usbc, blinkenlights and onboard wifi - much easier on Newegg than Amazon, but unfortunately it suffers from the aforementioned issues).
brilliant. the logging bit has been slow, and this seems very helpful.

> makes it run without forking

what's forking? I didn't find much in a query (https://duckduckgo.com/?q=nginx+forking)
You're out of luck, the data are still relatively sparse, (understandably) collected under duress, and (understandably) without controls. Just about anything predictive (and many descriptive things too) any reputable scientist says will be slightly better than informed speculation. The ethically sound scientists will disclose the level of caution their suggestions for policy entail, and there will be plenty of very talented scientists who will raise a furor on the grounds that the layperson cannot be trusted to take socially responsible action without an exaggerated threat over their heads.
> there are laws which give these powers

IANAL, but I know some of you are so I'm asking here. I've read that challenges to these orders will not succeed because of emergency declarations. The emergency declarations are supposedly backed by some law, correct?

Don't we have a document in the national archives that guarantees things like peaceable assembly and not prohibiting exercise of religion? Yet we have people being arrested or cited for assembling, and pastors being put under arrest for holding church? Is it the temporary nature that allows this to be done?

Regarding the law that allows this kind of stuff, how does that compare to a constitution which says "congress shall make no law ..."?
Sodas, chocolates, tea... if you didn't frequently have caffeine as a child, you're probably in the minority.

Café Central is probably historically most important cafe. It seems like everybody was there at some point. The list of regulars and visitors is who is who of the 20th century.

For the short period (20 years or so) in the early 1900s Vienna was where the history happened and modern ideas were born. Then everybody scattered around the world and executed those ideas with varying results. Philosophy, math, psychology, physics, economics, politics (left and right) you name it.

In 1913 Hitler, Trotsky, Tito, Freud and Stalin lived within the same square kilometer.

Nobody said it was going to be simple. I'm just advocating that it not be completely and totally lacking in stated goals when it's such a severe policy intervention.

Those goals could be complex, or detailed, or multivariate, or subject to contingencies and caveats. But they can't be non-existent and they can't be secret. This is a democracy.

> The fact that SF does ok is a result of the shelter-in-place order, without it SF would look like NYC or worse.

Your sentence here is making a quantitative assessment that the result is worse than NYC, without stating the metric you're using to arrive at that assessment, or hinting at the means by which it was arrived at. It's just "worse".

That's fine for an forum comment. But it's a disaster as a government policy almost six weeks into this crisis.

What's being criticized here is the parent story, which is a press release by the actual government, and appears to make no mention of the criteria used to arrive at this drastic and staggeringly expensive policy decision, and contains nary a hint of what metrics they'll use to evaluate it, or critically, determine if the schedule should be delayed or accelerated. That's crazy.
I'm starting to see these arguments take startling similarity with the anti-vaccine arguments.

Which is that vaccines aren't necessary because people are no longer dying from said vaccinated diseases. Perhaps it's important to consider that one of the reasons why the doomsday predictions haven't came true is because places took action early.
Can't say I find that argument all that compelling. Using the logic from that article, functions that perform side-effects have a different colour from those that don't, therefore we should prevent all functions with side-effects to enable better interoperation? I suspect the author and most other programmers might have some disagreements with their new monadic overlords.

The point is that "colour" is introduced to make a meaningful distinction in order to achieve a desirable property. He's enamored by Go which erases this distinction, but it does so by giving up nearly all of the benefits of the event-driven model: very small captured state for resuming the continuation.
Why? Their margins haven’t changed. If anything, they’re tighter than usual due to extra precautions

I think this is mostly a disagreement around terminology.

The GP is referring to purely functional languages like Haskell, where functions don’t have state and are referentially transparent. In Haskell, useState would have to use a monad.

Racket (and Lisp in general) has mutable state so doesn’t guarantee referential transparency. You can definitely write pure functions, and that’s good style in many contexts, but it’s not required or enforced.

I personally agree with the GP, and assume “functional programming” to mean pure functional programming. It’s common to use an FP style in non-pure languages, but I think this is FP if and only if you completely avoid state.

Well, there's a very real systems level concern there. There are anecdotes - just anecdotes, but it'll already be a disaster if we start getting data - of workers yelling at business owners for securing the PPP funds to save their jobs.

twitter had/has so called "zero rated" deals with most carriers, cut way back when. They dont(at least they didnt used to) pay anything per SMS, for most carriers.
However, the infrastructure to go direct to that many international carriers is/was quite complicated, from both a technical & ongoing business management PoV (carriers are awful to deal with in both categories). i imagine the savings from no longer having to maintain either are quite substantial.

One interesting thing that pops up on reddit every now and then is that pregnancy going wrong is surprisingly common, yet it's not talked about that way at all - most people talking about it seem surprised that it's actually somewhat common. It's like pregnancy going wrong is reserved for specifically infertile/something people, rather than the dice roll not being 9 wins to 1 loss in the first place.
