15 year old High School sophomore noob here. We (crazily) are attempting to put up a CubeSat (shameless plug www.seakingspace.com). Using the Lora SX1268 433Mhz we tested the Semtech transceiver across the Catalina channel. 25+ Miles SF factors 7,9,11 at 125 BW. Worked great. We did a link budget and should work over 500KM line of sight no prob. The SX126X is the new improved version of the Lora chip. Im sure a verion with it will come out shortly.
Is this causing any actual or damaging confusion? Why care?

This pandemic specifically requires assistance breathing for a huge amount of people. I'm not sure how closely that correlates to hospital beds, but it could be a big issue in the US where many hospital-like things are dealt with by urgent care.
From the article:

> Public Health England had started tracing people she had had contact with, and the department and her parliamentary office were closely following its advice.

So that will probably happen within a day or two.
Indeed, they were implementing preventive measures as early as December 31 [1].

So it's AWS's version of CoreOS?

I wish somebody'd take some VC or R&D money and build distributed computing features into the kernel itself, so we could quit wasting our collective engineering talent, time, money and energy on distributed applications that run on non-distributed-operating-systems. It's like nobody wants to work on creating a round wheel, so instead we're spending all our time building custom roads for square wheels.
Look, the bottom line is that given the obvious unpopularity of right wing leadership on most popular online outlets (most news media, especially online, Reddit, Twitter, etc) literally anything that they do is going to be criticized.

Probably better to avoid posting about them on HN.

You're going to hear about everything negative that they do, but you are unlikely to hear much about the positive steps that they take. 2 examples:

1. Trump ordered millions of masks from 3M weeks ago. Did you hear about that? [0]

2. Trump is proposing payroll tax cuts until the end of the year [1]. Did you hear about that?

My point isn't to defend anyone, just to emphasize that any news you hear about what politicians are doing is likely to be heavily skewed towards negativity, even when undeserved, so take your propaganda of choice (left and right) with a hefty grain of salt.

I think a lot of Tesla is simply that they're not the other guys. They're giving people what they want. The dinosaurs have been refusing to innovate in many areas, screwing customers with exploitive dealer networks, dragging their feet on features when it's demanded of them, or just plain making everything miserable about cars for decades. The dinosars deserve to get their ass handed to them until they wake up and serve customers.
I used to work near MIT. At least several years ago, there were surprisingly few places to buy a decent meal near campus. (By surprising, I mean because there were also numerous businesses in that neighborhood with lots of well-paid employees.)

The area also has/had a small number of food trucks at lunchtime (only) IIRC.
> A timestamp is a point in time, whatever the time is in Paris or Tokyo. It is an abstract value and it is way better this way.

> Timezone is extra styling information, just like CSS.

This is an incredibly reductive view of time data and the possible applications that use it.

Not all time data is timestamps, and UTC timestamps strip out information that is not "styling".
Yes it’s a lot like going for it on 4th and 1. Statistically you have a better chance of getting a first down than not but no coach on the planet will risk it. In my own experience I worked remote for many years and I was incredibly efficient but I also was outside of the office politicking which was good and bad - for me it was probably more good because honestly the less I’m involved in politics the better. Later when I confounded a startup our mgmt team was 100% remote as a consequence of all having prior worked at a large company with many offices. It was productive but we found ourselves having more frequent and longer off sites to compensate and eventually we did coalesce most employees in one of three locations though many still had the option of remote. I enjoyed it a lot because it prevented work life from becoming too routine and we were still productive.
I’m not sure about mit schedule, but at Harvard, which announced same measures earlier today, the students has to vacate dorm rooms at the end of the academic year anyway. This happens at the end of April. So essentially Harvard is asking students to move out 6 weeks before the end of the year. One of those weeks is spring break. I’m sure students are in shock and there is a lot of chaos on campus. But according to what I heard preventive school closings are much more effective comparing with reactive closings after people are already sick. I hope it is for the best and feel bad for all the parties - both students and school administration that has to basically abandon all work and figure out what and how to proceed.

What I am concerned about is this case in town next to Cambridge where elementary school student tested positive and school remains open with “advice to self-quarantine” for “close contacts”. The town officials thought it was sufficient to close and disinfect the school for one day and then to reopen it again. I find it very disturbing.
That’s not what I’m arguing, and I believe ESR wasn’t being intolerant of her, but rather some of her views.
In 1998, Linux was still behind SunOS/Solaris in maturity and even if it had been even, Intel x86 hardware wasn't remotely on par with what Sun machines could do.
Tesla has lost $6.5B over 17 years. It’s cheap money which has allowed it to persist despite these losses.
Does the author really think that the creators of what he calls 'supposedly hierarchy-free companies' don't meet Chesterton's bar? That they swept away hierarchy without having first thought about why hierarchy exists in the first place?

Or does he perhaps suspect that they haven't thought about it enough? After all, they can't have truly understood why hierarchies were first instituted, because they have failed to see the benefits he so obviously believes hierarchical organization has.

See, this is the problem with Chesterton's fence. You tell the reformer to go away and think about why the fence is there, and then she comes back and tells you the fence was put there to keep her out. And you say 'ah, poor child, you still don't really understand why the fence is there.'

Sometimes the burden of proof needs to be the other way round.

We're ripping out that fence. And if someone wants to keep it, they need to go away and think and, if they can tell us why that fence needs to continue to exist, only then can they stop us.
This is technically correct, except that almost all JSON libraries parse JSON numbers into either 64-bit integer or 64-bit double, so you get those lossy conversions anyway.

I've worked on a production app where we had to swap out the JSON parsing libraries in the server (Rails) and all clients (Android, iOS, Rails again) for ones that preserved numbers as BigDecimals. This was a huge pain, it made everything slower, and even then it wasn't ideal because different BigDecimal libraries aren't even necessarily compatible. Foundation's NSDecimalNumber has different limits than Android's BigDecimal for example, and these are the types used by the parsers so you can't just get the raw data to do it yourself.

If I had to do it over again I would never rely on JSON's decimal support. I'd rather stuff my decimals in strings and parse them myself.
Why not get a Renault ZOE instead?
Nor will in-person, small group seminars be moved on-line. It might be fairer to just extend spring break for 2-3 months, and pick up the semester again in May or June.

Or, refund this semesters’s tuition, room, and board, and give everyone a do-over until next fall. (I am assuming the virus will burn out in 2-3 months.)

Maybe the best outcome would be radically improve remote learning, this time with full institutional support.

It’s fine that Tesla is a compliance car manufacturer for hire. Just don’t claim buying a Tesla is good for the environment, because it is not. Every Tesla sold just allows for one more gas guzzling SUV to be made. Instead, focus your energy on lobbying the government for stricter emissions regulations.

I wanted my next car to be electric and found the same thing. The good options at the time (Leaf and Bolt) are ugly, so I purchased a Model 3.

That being said, if Honda releases their little wagon thing in NA, that might be my next EV. If not, a Y is in my future.
Yeah, honestly not very often. Mostly they're second nature to me. I mainly just think of it when there's a topic of / vs \ like in this thread.
We are way past containment. Obviously containment has failed. It is not contained.

We need to be focusing on mitigation.

Containment and mitigation are two entirely different strategies.
HP also was a leader in device ergonomics. Their devices were pretty and easy to use, as well as reliable.

I don't think anyone had offices. It was all cubicles. (I worked at HP Labs in the 80's and met both Bill and Dave a couple of times.)

One cool thing HP had was "lab stock" cabinets on every floor that were full of free-for-experimentation ICs and other components. I think it's likely that the Apple I and Apple II computers were designed using components taken from those lab stock cabinets. (The story is that Steve W. tried to get HP interested in producing the Apple computers, but they just wouldn't go for it.)
So what happens if you lose a trusted device? Or maybe it crashes, or the user signed-in with incognito originally, or anything like that? What's the recovery mechanism?

They already do that. It's not quite "LIVE", but it's close. When you sign up for a certificate, you take the course along with a cohort of other students during a preset period of several weeks. There are staff and other students available to talk and answer questions in a shared forum, your work is graded, and the lectures/homework/exams/etc are spaced into weekly modules.

Sadly, the quality varies wildly between institutions and it doesn't seem to work as well as an in-person education for most people. But the affordability and availability make them excellent for helping to expand equality of access and get people started down the road of becoming proficient in specialized topics.
Should we be calling this branch of science electrophrenology?
> Instead, focus your energy on lobbying the government for stricter emissions regulations.

I focus on solvable problems. Tesla solves problems today that the United States Congress might never solve (a carbon tax is extremely unlikely to pass with the current legislature configuration). Every Tesla sold gets us closer to a zero emissions future. You go to war with what you have, not what you want. Dysfunctional government? Those factories still churn out EVs that generate revenue to scale up battery manufacturing across the world.
Seems pretty cheap?
It certainly may appear to be broken all the time. But that's the price you pay for using the vast Emacs ecosystem. Emacs over the decades has accumulated an incredible amount of things - built-in and third-party packages, different ways to work on various platforms, protocols, screen-sizes, languages, etc.

There are tons of code written in Emacs-lisp on Github alone. None of them, not a single developer contributed to Emacs ecosystem, has ever gotten paid, except for a few, small, voluntary donations. Almost all of that work is done by individual contributors. If you think about it, Emacs, to a certain degree, defies any logic - the way how it's concocted shouldn't work at all. Yet, it does, and some features of it done is a particular, astonishingly clever way, that no other IDE or editor has ever successfully replicated them.

To become a serious Emacs user, one has to either choose to be austere and handpick the packages to use or has to become really good in debugging the problems when they arise. Learn Emacs lisp, learn how to use built-in profiler, "toggle-debug-on" functions, learn how to investigate slow/failing startup, how Emacs loads packages, and you can update things with no fear.

Yes, sometimes things break (show me a software product with no bugs), but for me, it never takes longer than a few minutes to either find a fix or a workaround. From my perspective - Emacs is very stable.

The transmission/storage size of shaders isn't important. Textures and 3D models dominate in any non trivial project. Kind of like dieting by trimming your toenails.
> Tesla's 10-K shows an accumulated shareholder deficit of $6B. That's over and above money spent to buy factories which are still operating. That's $6k a car at 1M cars sold.

The money was spent on things like R&D and product development. That means you amortize it over the total number of cars they're ever going to make using that technology. They've made 1M already, but why would you expect them not to make any more?

Some of that money went into developing models that haven't been released yet. If you break it down per model using existing sales numbers then those models would have cost infinity dollars per car, but that's now how it works.
I come from outside of the Python ecosystem, so I'm not familiar with the specific frameworks mentioned (I read the original post too).

Can someone simplify the argument that she's making about them? Something to do with maintaining separate, blocking threads in anticipation of requests vs spinning things up as you need them? Or is it a criticism of dynamic languages as HTTP servers in general (it's not clear what language was used in this article)?
Tesla has spent $20B so far. All of that money created a burst of carbon emissions which they haven’t yet offset though EV sales: especially since they sell pollution credits to other manufacturers. They’re still deeply in the hole.
No cars? How do you leave a city? I could imagine a world filled with an automated uber-like service of self-driving cars, but what would replace cars for going to work in a small town?
I agree with everything you've said except the part where you imply Chesterton was wrong to charge the demolition-proposer with a duty to do research. That duty absolutely still also exists. In the situation described, even if people putting up fences have a duty to record why, the time for that to happen is long past and there's no utility in complaining about it. It's natural not to bring it up, especially if you assume that the records do exist in some dusty church or town hall attic.
How about you write a simple binary substitute that covers just the standard JSON (number, string, true, false, null, array, object), see how you do compared to the existing JSON serializeres / deserializers and MsgPack.
For some reason I was under the impression that recording meetings was illegal.
> I'm pretty sure we would have noticed if attending an authoritarian school gave you an authoritarian personality style

Wasn't it noticed though? Paddling students fell out of favor decades ago, in no small part I suspect because people began to realize that hitting kids wasn't teaching kids how to resolve conflicts effectively.

The status quo before 'zero tolerance' was itself a radical departure from what came before it.
It absolutely will fly. There are centuries of Supreme Court precedent on this very topic in the US, sometimes under difficult circumstances. Some rights cannot be circumscribed under any circumstances regardless of consequences except in very narrow ways, there are no exceptions for emergencies. The right to travel freely within the US is recognized as one such right. That's like telling Americans that we'll temporarily ban free speech or ban guns -- it isn't negotiable to a large portion of the population and, furthermore, States have considerable power to make any such bans unenforceable.

The few historical examples where the courts let enforcement of elementary rights slide for a bit due to "emergency" are almost universally national embarrassments because of the abuses that followed. Judges aren't keen to be named and shamed as one of those people that let that happen for the sake of expediency.

Maybe in other countries but not in the US. It is a fundamental misunderstanding of how individual rights work in the US.
I’m not surprised. Just look at how many “eng hiring is broken” threads on here.

If software could help you hire candidates that are 10% more productive and stay 25% longer (numbers pulled out of my ass) than the candidates you hire now, how much do you think your company would pay for that?
It's weird for open source because the ousted party can usually take the tree and fork. A prominent example of this is OpenBSD, which started with Theo being ousted from NetBSD. In many ways that fork is now more influential than the original.

My initial reaction was to compare your sentiment to nation states and consider it in its extreme to be a justification for despotic behavior, though your comment tries to rule that out. After further consideration I think the OpenBSD example is more illustrative and a more constructive reply. Outside of licensing wars which sometimes happen, there is not always a need to be the "original" fork.
This is possibly the worst metric as it can mean so many things.

Here [1] we have more numbers.

Most importantly the # of beds seems to correlate strongly to the 'average time in hospital' eg. Japan has 3x beds but stays are 3x longer. That stays are shorter is not an indication of poorer quality.

The US has fewer doctors, about the same nurses, but 3x more MRIs per capita, and probably similar inventories of other kinds of equipment.

As for respirators? Who knows. But The US is a major exporter of medicine, equipment, and they spend considerably more. Just like in every major war there's a 'key weapons system' that wins the day while the underlying economy wins the war ... the US might be in a decent position with enough equipment, and a resilient enough economy and populace to fight coronavirus.

Don't be fooled by Trump's shenanigans, Americans are not fools. When they decide to do whatever they do it in a way that few can match. FYI I'm not American.

There will be ugly issues for those without insurance but I suggest that states will take over there with emergency solutions or else they'll all be voted out of office instantly and they know it. Even Trump isn't stupid enough to fail to recognize that people dying en masse on TV will make him look, in his own terminology 'really, really, really bad'.

Also, thankfully, once again, North America seems to be a tiny bit isolated from the 'rest of the world' and has just enough time to see what's happening in Italy and can possibly act a little sooner on some things.

I expect lock-downs and social distancing measures to take effect earlier in America on an per-capita-infected-basis.

we also have the cruise ship though or the death rates outside of Wuhan in China (about 0.7% so far) and they have a lot of recovered cases. Rather than everyone somehow lagging behind Italy's death rate I think it's likely that they have just lost the plot and there's a huge number of cases under the radar.

>I'd say nobody is going to shut down whole megalopolis cities if it was just a more severe flu.

I mean a severe flu by a factor of five or so is basically what this is, it's just that this in and of itself is really, really bad because nobody has the capacity to handle that many cases.
Yeah, for the less energetic stuff. The same issue applies, the very energetic stuff just sails right on in. Big EM fields also don't deflect neutrally charged stuff like Cosmic Rays and neutrons. Radiation shielding is hard stuff and it'll take multiple methods working in tandem.

> If you don't find yourself studying 6 hours a day, you're not getting an elite education.

Seems like an unhealthy attitude to me. I really dislike the perspective that education is at its best when the learning is most difficult. The best teachers are the ones that make things as clear and digestible as possible. Bad teachers are the ones that want to see you sweat.

You have to look at the issue from the organizer PoV and not as the event goer. You need to have some kind of reliable communication channels for the staff. The result of 10 years of experience of trying to cause that is for me that analog UHF radios work, wired VoIP phones work and just using whatever smartphones the staff works and combination of these three technologies gives you the SLA level you need. DECT is meaningful solution of the same problem, but the handsets are expensive and even more so if you want some broadcast/PTT capability and ideas like “well, we have bunch of Nokia S60 handsets that should in theory support wifi as LTE/CAE radio layer” is pure nerding-out that does not solve any kind of real issue and instead creates new ones

Just to speak up for those that are struggling with the headlessness of v7... I have a small team with junior resources that had to build a table in React.

1. This is a required response to the crisis, not something noteworthy. They're ordering masks because they didn't have enough and as we see now they're already running low.

2. How in the hell is yet another tax cut a positive development? How will that affect the course of the crisis? Even as an economic measure, it will help no one who loses their job. Just asinine.
