Covid-19: the largest remote working experiment for the future
I'm not even sure what this "no innate immunity" sentence means. Old and fragile people are getting vaccined for flu every year, because they aren't immuned to the new strain of the year.

Now it is true that old and fragile people should be worried about coronavirus, but judging from death rates, it doesn't seem more deadly than the flu. So why put fear in the whole population ?

also, most people only experience nothing more than a cold symptoms. Which means most people actually have an immune system able to fight this virus quite efficiently.
But the government is the main customer of Clearview AI, so why would the government remove it’s own access to a tool?

For those who haven't been paying attention to the comedic effects of intellectual property taken to the extreme (or logical conclusion, I'd argue): just punch "tractor dmca" into your favorite search engine. We often take for granted that people in this sphere are aware of this sort of insanity, but unfortunately that really isn't even close to being true.

> Secondly (and this can be seen as both a flaw and an advantage), both Flutter and Dart come from Google. The good part of it is that Google is a tech giant, and if they want to maintain something, they have the resources and manpower to do it. The bad part is that while Google is known to introduce useful tech and services, it’s also known to kill off or retire them when they’re deemed obsolete.

I think over time the crippling of Google’s developer initiatives because of this perception will cost a lot more than all the money saved from all the retired services.
There is some times during this thing where I have actually panicked for sure.

Its the first time in a while I could feel myself teetering on the edge of losing control and succumbing to a full blown panic attack.

Reading the news is actually pretty scary. Even the way individual cases are being reported is freaky.

I wonder how I'd feel if the same thing happened for every freak accident, flu death etc.

Not trying to down play the severity of the virus, just amusing how much we can be influenced by the media.
I've picked up a lot of anecdotes from various serviceman about the war in Afghanistan and I wonder how much of it is true.

> work with the locals after the initial invasion

1) Isn't it an ongoing meme in the US military that ANA troops are useless and that the government is corrupt to an unimaginable level?

2) Didn't we also originally burn their opium fields, only to allow it to become once again one of there chief economic exports since it was so vital to the local economies?

3) Is it true we had a formal policy of allowing elder tribal leaders to systematically rape young boys in order to be more accommodating to their local customs? Including trading viagra for tips on insurgent activity?

I realize some of these questions are pretty sensitive and may be uncomfortable to answer. It just seems like it needs to be brought up whenever we talk about the Afghan war (while it's usually swept under the rug...).
During the plague years, airborne lead levels in Europe fell to 0.

When the sickness came, it caused massive social upheaval in the populations it infected, shutting down entire human industries as ravaged communities went into damage control.

One of these affected industries, according to historian Alexander More from Harvard University, was lead mining and smelting by medieval workers – and thanks to his team's new study, we've got more than historical records to show that.

>they needed more compute power than they could afford

I wonder why this problem doesn't get much more attention in the field. It seems like models to solve even extremely domain specific, limited tasks already are running into economic / computional constraints.

Given that openAI wanted to be a place that develops general, artifical intelligence without having so much short term commercial focus I wonder why there is not more research going into approaches that are less computationally intensive. Which IMO is in itself a metric for intelligence
Batteries retaining 80% capacity after 4 years of use is defying the law of physics? I am pretty sure battery longevity isn't constrained by physics. Lithium batteries in the Tesla last more cycles than the ones in your phone. Why because, Tesla warranties the battery for 8 years. Cell phone manufacturers just need the battery to last 1 year so they don't care.

And for people who downvote me, the reason we removed mercury/cadmium from batteries was during 90s government threatened to heavily tax batteries. Car industry in EU is also heavily influenced by penalties around gas mileage.
That’s an incredibly useful table! Do you know where the data in that table came from?

I wouldn't be at all surprised if it's just bad project management.

You know how, when you really need to something accomplished without delay, you pursue two paths in parallel, so that by the time phase 1 comes to a close, you've got things ready for phase 2? Well, maybe the CDC doesn't.

Obviously they do on some level because they did develop kits (which had problems, which delayed them). But it's one thing to give lip service to getting started on stuff you're going to need in the near future, and it's another thing to commit to it and follow through with it and make sure it happens.

Also, I'm sure they were super busy and had other priorities, but lack of testing means the country is flying blind, so this should have made the short list of priorities.
>Yea but consider the cost. Just slinging weld on a tank costs time and material

Sure, but its what, A few 10's of thousands of dollars for steel and welding for the test? If it saves a day of double or triple checking to just ""see if the damned thing blows up "" you have to weigh success odds and lessons learned vs. overhead costs. I wonder what a few days or weeks of overhead costs a company like SpaceX that would have had to be spent to make sure the test succeeded.

As a rule of thumb, calendar time is generally more expensive than equipment and man-hours - even in hard tech.
There is little evidence of that other than people manipulating the numbers to favor that outcome.

Even within China, Outside of Hubei the fatality rate is just 0.4%.

This 10x nonsense is so utterly bogus. People literally can not think for themselves anymore. Just read and regurgitate FUD.
> First, I do think it's ridiculous that he takes it as a given that Oligarchs favour climate policy.

> I don't think any serious survey of the financial interests of the global superrich will support this view.

There is a subtlety here - one possible outcome is oligarchs cynically favouring climate policy while simultaneously having deep vested interests in fossil fuels.

The article isn't saying that the oligarchs want to do anything about climate change; the idea is that they are very keen on the principle of using centralised power to control others and will attach the things they want controlled to climate policies as implemented.

If I owned an oil company then backbreaking legislation that means nobody can start a new oil company would be strategically interesting; for example. Big companies don't fight regulation tooth and nail. They accept the regulation then lobby for loopholes that favour them and restrictions that disadvantage competition.

It is, in fact, rare to see a corporation moving to deregulate industries. They often fight changes, but rarely organise to reverse reverse things once they are in compliance with new rules.
There were over 100k US troops deployed to Afghanistan at the peak (part of 2010-2011). Between 2009 and 2013 it was over 50k.

The Soviet Union deployed over 115k for several years. The amount of fortune spent was a serious accelerator for the decline of the USSR.

Afghanistan is a large, dispersed, and landlocked country. With huge amounts of weapons from many sides. Decades of war. Little trust between population groups.
The glutton free products of today are so much better than the original products in the 70s and 80s. Those were truly terrible as you had to replace everything with glutton in it. It feels so cruel to make a child eat special foods that their brothers/sisters/parents don't have to eat but the alternative is they fall severely ill.

People who have or are related to those with Celiac Disease know it's life threatening and not a joke. That's why it disgusts me when people see it as a fad or claim they need to eat glutton free for health reasons. They are clueless.
> It's a even harder challenge at professional dinners that are prepared by well-meaning colleagues.

This has always been my biggest challenge that can get awkward quickly.
Could you leverage information in zfs snapshots metadata to drive things like this? The copy on write semantics inherent seem plausibly related.

Playing Star Wars on the ESP8266 with Micropython
I believe education is important, and in the United States, it is wildly underfunded at the K-12 level.

However, blaming people for being under-educated is probably as misguided, and immoral, as yelling at a short person for not being able to reach the top shelf in the grocery store. It's as wrong as going to a mental hospital and yelling at the retards that they just need to try harder, go out and get a job, and start supporting themselves.

Humans have variable intellect, and our society really wants to deny that. Sure, it's good to treat people like they are capable of making smart decisions, but the evidence is overwhelming that many of them can't. There are people who really can't tell what is real from what's been made fake. And that's not just a problem with the lower IQ people: Look at fakes in the art world as an example for how highly trained and educated people are still fooled.

So, what are the best policy decisions in a world where a significant portion of the population can't tell a half-decent photoshop from reality, or a sextortion scam from actual sextortion with real evidence?
I see, thanks for the feedback. Going to check that out.
Ask HN: Good ways to capture institutional knowledge?
Successful companies institutionalize the knowledge of their employees; this leads to better continuity and faster on-boarding. Things like huge monorepos of useful code, internal tools, process manuals, etc. are example products of this. Young companies tend to depend on the dedication and talent of key individuals, and in maturation, must somehow make the jump to institutionalized knowledge (so that "if someone got hit by a bus" things are ok). What are some successful methods you have used or seen used to accomplish this transition? What are problems you faced (skeptics, opponents, etc.)? I am involved with an organization that is slowly growing, is about to lose key personnel, and is looking to prepare.
Is there a term for this flowery, overwrought writing style that takes half a page to make a point?

You are assuming the "yeomanry" mainly consists of the old, but I think that's an overly narrow and basically false assumption. The participants in the yellow vest protests in France - largely members of "yeomanry" I would think - are as much Gen X and Millenial as they are Baby Boomers.

As for the oligarchs, there are certainly wealthy individuals entrenched in the traditional fossil fuel industries, but the number of these individuals is dwarfed by the oligarchs in Media, Finance, Government, Technology etc, who are much farther removed both in business and culture from traditional modes of energy production and as such are able to take and advocate for radical positions on environmental policy without regard to the consequences for the "yeomanry".

This story plays out across the spectrum of issues that society contends with today. In general, sometimes for the same and sometimes for different reasons, elites in the corporate world and also members of the "clerisy" both desire a breakdown of traditional society to further their own agendas. In the case of the former that agenda is defined by profit seeking and in the case of the latter it is defined by philosophical and social beliefs.

So you see, I think while this piece is vague and steps on its own toes at points, it is addressing a real conflict that exists and is growing in contemporary society.

Using Dart in flutter feels like Google was trying to avoid tossing away a bunch of pre-existing work by finding a purpose for it somewhere. It's Lars' sorta Java, sorta Javascript personal project and it just doesn't have any sort of design to it. Dart's failure in the web space showed that there wasn't any real demand for it - it just wasn't better enough.

I realize they can't use Java, but this is a weird horse to tie themselves to.
What's a rocket but a tractor with a few tens of thousands of lbs of fuel and oxidizer strapped to it?

I'm a fan of learning enough to know how to get going, then just start building. In the process of building you'll get stuck and have to look for answers.

As for are there better tools, I don't know what your needs are. Is this for fun? Do you have a budget? Are you doing this for resume building? It's not a question of what's "best", but rather what's best for your needs.
This is surprising for event recording since they should be equivalent but time + zone is strictly more likely to be messed up. E.g 2:30 a.m. is two times during daylight changeover so you must correctly specify est or edt.
Precisely, get yourself five digital devices that track time, and see how many of them are even accurate to the second. Probably none of them. But implementation of leap seconds would only make sense on systems that at least fulfill that minimum criteria.

Leap seconds are things for stock market servers, atom clocks, scientific devices and the like.
That's the right idea. How do we allow per-process or per-page encryption of memory with hardware attested keys? Imagine if you can plug in your own key store from an HSM. This starts to really create some interesting defenses against very common security enterprise threat modeling.
This essay is a total mess. This “neo-clerisy” thing to me smacks of tribalism dressed up, ironically, as public intellectualism. It’s a fractal of cognitive dissonance
I tried out flutter in the past few weeks and it seems really great, especially compared to the android framework. Dart also seems to fit in really well.

But I do have some criticism for dart. While it's nice that they moved to a static types, they still made every single type nullable. So e.g. if you get a boolean in your function, be aware that it can be true, false and also null. I have my problems with java having nullable objects, but having the primitives also be nullable?

Well, I'm pretty much a beginner, so maybe there are better ways and I still don't know them. But afaik, they weren't mentioned in the brief Dart intro on the flutter page.

Dart does also have some cool things, though: Extensions (for adding interfaces to existing types), explicit getters, async/await and lots of syntactic sugar. Building your widget-tree in dart sometimes looks like a declarative style similar to xml, but far more concise, except that it's really imperative, which is really cool. No long

Component a = new Component();

a.setOnClickHandler(xyz);

a.setColor("green");

b.add(a);

I've been living without a mobile phone for about 5 years. The only time it has ever registered as slightly inconvenient for me is while travelling - specifically the airport pickup coordination. I simply don't use services that rely on thoroughly busted mobile phone 2FA - and I'm honestly dumbfounded that anyone with any understanding of 2FA and the insecurity of telecom networks would, given the fact that a lot of services use it for password reset.
I have a tendency to learn stuff in reverse. I used to make an SD Card ready, connected monitor and keyboard and enabled everything as needed. Then I got the task to deploy n-RPi's and looked at the image first to customize it for the requirements we had. That's when I looked around and saw the unusual unit file and tried to understand why the service would look at the boot partition to start a service. In the end I think I added the symlink to start the service thorugh systemd.
Timex Ironman bought within the last two years, almost certainly less than $20, says 3/1 Sat today. The numbers on the back might say "029 36". Or maybe "029 56". I'm sure its innards are the same as most of the other sub-$20 Ironmans.
People don't pay attention long enough. We have 20 solid years of non-stop doomsday predictions, all of which were wrong. Nobody pays any attention to this, they just go right on believing all the new baseless doomsday predictions. Meanwhile actual looming disasters are ignored.

Yeah this essay is a mess. Smacks of sociopolitical myth-making, not credible analysis. The thing it seems most like is a vehicle to lump scientists into the same category as religious figures. Bare tribalism wearing the clothes of public intellectualism
Running "serverless" functions on https://github.com/bytecodealliance/lucet which is running in these enclaves provides a relatively simple way to offer "confidential computing" to offer an alternative against "semi-honest" (or sometimes known as "honest-but-curious") adversarial threat models.

I think the risk of Flutter getting cancelled is very remote. Google knows they have a winner on their hands.

Flutter is the UI framework for Fuschia. It is picking up huge momentum [1]. The support for native apps and web[2] is still immature, but promising.

Flutter brings the joy back into UI development. No messing with CSS, tables, etc. - "everything is a widget" makes for a very composable framework that is super fun to use.

One of the recurring complains / concerns of Pakistan is/was that Afghanistan post invasion was cooperating too much with India. From what I understand (which is certainly very limited) that was more fear than reality. But from the POV of Pakistan's,hugely anti-India, military, it's not that hard to understand how being encircled by India and a "puppet state" is seen as threatening.

I think there's pretty good evidence that the ISI has (does?) financed/organized training camps for anti India groups (like Lashkar-e-Taiba) in Afghanistan.

Why are you assuming more people flying is good? The evidence is that too many people are flying. Now we've made everyone used to a thing that will either be taken away by governments proactively or by nature retributively.
It was a bad idea to go in. Having done so, killed so many people, made promises to so many more, pulling out is frankly disgraceful. America and the other countries involved have set that country back at least 100 years socially and ruined millions of lives.
Your comments about Rome are completely incorrect. There are four main memory controllers in this architecture and some of them are further from some CCDs than others. In the worst case, accessing the furthest-away controller adds 25ns to main memory latency.

You can put this part in "NPS1" mode which interleaves all channels into an apparently uniform memory region, however it is still the case that 1/4 of memory takes an extra 25ns to access and 1/2 of it takes an extra 10ns, compared to the remainder. Putting the part into NPS1 mode just zeroes out the SRAT tables so the OS isn't aware of the difference.

But don't take it from me. AMD's developer docs clearly state, and I am quoting, "The EPYC 7002 Series processors use a Non-Uniform Memory Access (NUMA) Micro- architecture."
Probably the right decision then. As I don't put them on public networks and delete the pi user this is of little concern to me, but given the target group, it is a simple safety measure.

What you want is called PAPR.

edit: Avoiding the extra breathing effort is only part of the benefit. Respirators generally let a lot more pollutants in through leakage than through actual failure to capture them because it’s very hard to make a good seal around your face. A powered respirator can keep the internal pressure neutral or slightly positive, reducing the tendency for anything to leak in around the mask.
The only correct orientation for toilet paper is to keep it off the holder. Then you can hold the roll and "dual spool" to accumulate a nice fibrous lather with haste.
I don't think so (and I'm the type of person to never miss a good Google bashing). And here's the hot take i'll make for it: Google is not solely responsible for the bad PR they get for prematurely retiring popular services.

Often this is a conundrum of naive technologists clamoring to shove untested tools into production for... reasons? Excitement? Risk-taking adrenaline? I'm not quite sure.

Yes Google's marketing oversells (or even lies a la Google Stadia), but at the end of the day I think Google SREs/devs/evangelists expect (wrongly) some measure of common sense and restraint from users and that is just not there. For example, if you ever watched some of Kelsey Hightower's earlier kubernetes talks he practically begs users to deeply consider their use case and whether or not they should actually be using kubernetes.

Google also expects their users to SRE/devops/refactor/upgrade constantly like they're able to. Which is also insanely unrealistic.

Ultimately, while some cases are Google's fault, often the blame is shared - most of the time. The market realizes this and thus the opportunity cost is already priced in somehow.
