I agree - there should be no job that nobody will do, only jobs that people won't do at the price you want to pay them.

And what this really means, is that maybe certain products - like $7 bins of pecans from Walmart, or $1 heads of fresh lettuce - have been under a market that wasn't sustainable, and a lot of these food products that we take for granted should be luxury items again.

The compression part is definitely great work. It would be a valuable addition to the main prometheus repo if they accept it.
I think the author of Bitwarden should seriously start considering making the official daemon lighter as bitwarden_rs is just that good.

With a requirement to pay extra $5 on your server instance monthly for more memory to self host the official version, you'll be paying a lot more than $10/year.
Ask Barcelona. They're seeing issues with it driving up rental prices, and pushing the actual locals out of the city as landlords realize they can make more money using their properties for AirBnB, with little-to-no regulation, than they can leasing long-term. It also makes others who live in complexes dominated by AirBnB want to move, as tourists really don't care about how they behave and often come in at all hours of the night drunk and loud, and changes the neighborhod itself as businesses change to cater to the new tourists in the area as opposed to locals.

Hotels are specific buildings that aren't part of the real estate market that is let to ordinary locals, whereas AirBnB is. Plus, hotels are generally concentrated in specific areas of the city, and so don't ruin local neighborhoods.
The problem may not be that manipulated images are used to convince people that X is real or Y did Z, but that anything inconvenient can be written off, something that would require an order of magnitude less effort than employing the technology itself. This issue, of course, has always existed, to a degree, but now we exist in a state that is an unprecedented, in my opinion, acceleration of such tendencies. In a few decades, will it still be possible for there to be a reaction like that which came about from the video of the beating of Rodney King?
Lifeline currently pays separate subsidies for voice and data, see the link from my first post.

The quality of device has nothing to do with lifeline, which is device agnostic. The author's stated solution is also device agnostic.

As for concerns about bandwidth, they're kind of bunk, IMO. The argument by the author is that basic internet access is necessary to function in today's world, and Lifeline already exists for the express purpose of meeting that that need. A free-tier service doesn't have to be Netflix-friendly to be a success.

I think the issues you're attributing to corruption are just as easily explained by the low cost of the service. Whenever you're consuming a service at the lowest possible price point on the market, your experience will very likely be worse than the average, curruption or no.
some takes from the video (listening is better of course)

- corona virus was easily solvable as demonstrated by south korea, taiwan and china, but market failures cause by emasculated public institutions and companies more interested in selling consumer products exacerbated the crisis

- we are very dangerously closer to midnight on the doomsday clock (90 sec away) and seems the implication is because of the volatile situation in south asia (it seems he was implying india and pakistan?) caused by many things including climate change, and strongman leaders who also have no idea what they are doing (trump/boris) in the uk and us

- south asia is on its way to becoming unlivable, as certain areas last year reached upwards of 50 degrees centigrade; with continuously rising temps and increasing droughts this will only exacerbate tensions as time goes on

- we will get through the corona virus, but if sometching isn’t done about global inequality, the slow collapse of democracy around the world, and finally climate/environmental crisis, we will not “get though” it

- we are stuck in the ideology of markets and markets only, where private profit, not not societal needs are considered, and we need to break out of this ideology if we want to survive the coming crisis post-corona

- if there is anything positive to come out of this corona virus, it’s that people take the time to think about and act on what type of world do they want to live in, do we want to continue the same path towards destruction, or will we de-atomize ourselves and start to come together to face the looming problems (which are surmountable if we work together and pool our resources as people and countries)

I think there's one thing missing in your picture:

Those workers aren't necessarily unskilled. Those who come from my country(Poland) at least are often college graduates.

How do they end up there? Well, the pay is obviously better - especially for a seasonal worker. After all, the GDP per capita difference between the UK and Poland is close to 3x.

The unemployment rate here is(or was before the virus) considerably lower than the EU average, so had they not gone there those people would've found jobs and contributed to the local economy.

Instead we have this weird brain-drain in which the brains aren't utilized to their full potential.

Ironically I'm currently a "seasonal worker" myself, only I work as a software engineer, not fruit picker, or any low-skilled labourer.

Aside from that the coronavirus showed that this approach you present is unsustainable. Like I said before, currently there is so much demand for workers from eastern Europe (Poland, Ukraine, Belarus) that there's simply not enough people to fill all the positions.

Also we have our own fields with fruit to pick - all that is going to go to waste. That's definitely "less food produced" - just somewhere you don't see it.
yea... that seems the biggest problem for sure... i really hope apple builds in some mechanism for this soon
Was not an issue at all.
A constant 2nd-derivative means quadratic growth, not exponential.

I'm bit confused by the graphs, because they show the 2nd-derivative going to 0. But to stop this thing, we actually need to decelerate, eg going negative on the 2nd-derivative.
Question... What kind of software do you mainly work on?

I'm guessing it's not CRUD apps.
Historically Walmart drove out all the other shopping in small towns that was barly hanging on as the place locals went when they needed something fast. Until Walmart opened in my town we planned monthly trips to the city an hour away for most of what we needed. The local shops had some things, but the high prices and poor selection meant we couldn't afford to shop local often.

Note that Walmart of then is not the Walmart of today. They used to have quality products at a good price.
I can't tell you precisely how it was done but I worked at a company with many different types of hardware that contained many complex configurations of FPGAs, lasers, optics, and microcontrollers, coupled to a computer and they managed to simulate it quite well for what seems like a decade. One of the scientists there was one of the few geniuses I've ever met and they managed to simulate all those devices and a sufficient amount of their variations. So I can confirm it's possible, maybe it just requires an overworked genius?
>To me, version 10 of Mac OS is still the continuation of version 9 of Mac OS, even though they're fundamentally different systems under the hood.

Sure, and it carries over certain parts and leaves out others. Substantially similar? I'll buy that. Arguably the same thing, ontologically? I think that's a lot harder to prove, which is what the OP I replied to was saying.
In my opinion such misleading advice, especially the headline, it should be removed. The article is from January and has lots of questionable links how vitamin D works or "Changing seasons: Time to boost our immune system". Even the study linked talks about influenza viruses as if Corona was just a seasonal flu. 3 billion people are staying at home, countries close their borders, military got activated, it's not a seasonal flu.
Edit: I thought I was responding to someone, but I can't find the comment now.

I find that being open to new ideas, and allowing some time to prove them out rather than deciding beforehand, is the best way to find ideas that move the needle.

Senior comes to you with an idea? Great, prototype it, prove it out. Junior comes to you with an idea? Great, prototype it, prove it out.

Of course, you need to allow some time for prototyping.

When I ran teams, I told them part of their job was to spend the last half of Friday (unless emergency) prototyping their ideas and presenting their favorites at some point.

No one works the last half of Friday anyway, unless it's on this.
> Which would have the positive knock-on effect of the textbook being sufficiently obsolete every year or so that the students could no longer trade it in for credit, saving the bookstores money!

That's naive. E.g. SIMD is here since a good time and going to stay. So are GPGPU, with now quite similar architectures for tons of chips.

And Computer Science can actually be about science for real computers, and computers are not 8086 nor PDP11 anymore, and have never been a turing machine. So there actually is some existing generic CS and ongoing research that cares about cache effects and so over. Maybe it is applied CS if you want, and some kind of pure CS should not care about that, but I really don't see what should be the criteria to decide which is what anyway, so IMO there should not be any (but I do not mean that all research should care about e.g. cache effects, just that it is not really useful to attempt to distinguish between those which do and those which don't).

We don't teach advanced math by only showing what was done at e.g. the beginning of algebra. Neither should we stick to only basic subjects in computer science.
I could imagine some sort of signed-submission system.

The test device generates a QR code you can print or screenshot, and the inspector can scan that and it's either a device-signed message or a link to a repository which would say "this test was performed by machine 123456 at 2020-04-23 10:00:20, result negative"

If someone aims to defraud the system by having someone else take the test for them, or by forging the submission system, there's probably some fraud-related legal recourse.
> To mirror what some others are saying here, students should also be taught the realities of cache behaviour, SIMD-friendliness, branch prediction, multi-threaded programming, real-time constraints, hardware acceleration, etc.

They are in many places I'm aware of. At least, as an EE (at Stanford, but I've heard MIT and several others do the same), I had to take a digital system design class, but the majority of the class was spent on performance engineering. In fact, the very first (actual) project of the class was to take a 10-line piece of C code, which applies a simple filter in real time to a video, and make it performant. The initial code runs at around .5 FPS.

Our resulting performant code was, of course, many times larger (I think it might have been ~150 lines), but it ran incredibly quickly (110 FPS, iirc), by doing crazy compiler tricks and often calling ASM from within the C code, even though the asymptotic (big O) performance was exactly the same.

For context, this is not just a digital systems thing (my work is in mathematical optimization theory and my undergrad was in photonics and physics), but I do know that this class is not a requirement for CS since it's potentially too hardware oriented. The classes exist, but I'm not sure people are taking them.

What he is talking about is a proposed implementation of the solution. It isn't actually in the D language yet. No one's tested it (except for Walter). So I would definitely take its' validity with a grain of salt.

The bigger the map the better! When you have a ton of data points all mapped out Maltego has tools for you to analyze this data in amazing ways. You can sort of twist and turn the data to look at it in different ways to discover the meaning of it. Say you have a dataset of 1000 different hacks that have been attempted or conducted on your network. And you populated Maltego with tons of data. Source IP of the attacker, attack method used, port attacked on, country of origin of attack, time of day of attack, duration of attack etc etc. With Maltego you can identify patterns that you can't with other tools. Like you might see that 300 of the attacks all happened on port 337. So you can isolate just for that, then look for commonalities. Time of day? Tools used? Country of origin? In just seconds you can drill down to find some of these and start making a picture on who might be attacking you. I've used it and it's amazing for showing you graphs in ways you never thought to look which can help tremendously when doing research on certain things.
I've seen electronic speedometers that plug into vehicle OBD2 ports, and I know you can read the vehicle speed and other data using a wireless OBD2 adapter.

Would that not be preferable to this as it'd be a lot more reliable, granted I don't know which cars support them or not but I've seen them working in modern vehicles.
Bit like the ban effect, like many a record seen sales increase down to the aspect that some radio or other avenue deemed to ban the record.

Equally, once many heard news of something was being brought up, the net effect was to drive others into panic and drive them to do the same.

Panic begats panic. So you start to enter into the aspect of https://en.wikipedia.org/wiki/Crowd_psychology
Without knowledge of the hardware your software runs on you're likely to be one of those people who uses lists instead of vectors without really understanding the difference.
Also, as other people said, the shelf life for that knowledge is actually pretty long. Hardware will always be your platform, no matter how many layers of abstraction you have in between.
The basic speed up will not even be because of vectorisation. It will be because of caches.

Everybody has days when you just want to be lazy. A job won't give into that feeling.

Every job has something you don't want to do. Either it is tedious and boring, or it is hard in same way. Many of those things could be ignored (my windows at home are dirty...) in your personal life but the job forces you to do them.

The above factors means even if you love your job there are things to complain about.

Migrants can't make it to harvests because countries/states are locked down. Isn't that literally in the article?

There won't be any sources for a while because this is literally just starting.

I mean 3billion people are on lockdown of some sort globally right now. Not hard to imagine it may be hard for workers to get to farms across borders, or even within borders. CA alone will probably see a shortage of migrants. No, I don't know for sure but I'm speculating that it's quite likely.

Supply chains have also been strained because people have been panic buying for what, 3 weeks now? You can't just snap your fingers and double your supply of vegetables.
This is a crazy. The US (Connecticut) used eminent domain to seize people's houses to give them to a pharmaceutical company. They can use it to seize existing ventilator designs and publish them.

It sounded like farm picker migration from Mexico was on hold - no visas. But recent news suggest maybe not. Mexico could shut it down too - or might have a better time breaking their constitution to not allow their citizens back in on the way home.

Either way I would bet that with millions out of work unable to pay rent a backbreaking job sounds better than nothing. Especially if so much food is at stake send in the national guard if can't get enough bodies.

I think they're talking about the 2nd-derivative of the cumulative deaths. As they can (presumably) only increase, the first derivative is >= 0. The second derivative tends to zero as the cumulative deaths flattens off.

Edit: Now that I think about this some more, you're right. There has to be a decrease in the daily cases, which implies a negative 2nd-derivative. They mention "relative 2nd-derivative." It seems to be defined in the paper in a way that leaves me more confused:

> Daily fatality rates from the included countries were then used to calculate estimates of the relative second derivative of total deaths, N, 1/N d²N/dt², for a period of at least ten days.

Does this mean they are taking the second derivative of the reciprocal of the cumulative deaths?

I worked one summer doing migrant labor in agriculture harvesting blueberries in Maine. I migrated with my sister from elsewhere in the US. We were doing it because we wanted money and we were curious about the experience. Alongside us were poor people from Maine -- Native Americans and poor European Americans -- and migrant laborers from south of the border. There was a solidarity among all the groups, and strangely, between all these groups and our overseers against the land owners and Wyman Foods, our ostensible employers. One thing I saw was that the Hispanic laborers were in a lot better shape and in better practice than the other groups. Another thing I saw was that the people who got ahead disregarded the rules we were set. There was a particular technique in raking the berries we were to employ which would maximize profits for the landowners and minimize waste but which was much less efficient per hour. There was another technique, called sweeping, which would maximize the amount we harvested per hour at the cost of many more berries dropped on the ground, so less profit per acre. An advantage the migrant groups had on top of their greater fitness and experience was that they felt less solidarity with the landowners, so they were more willing to break the rules for their own gain. The overseers were cool with this, generally. My point is that this may be a pattern repeated across the globe. It isn't just that the migrants are cheaper and you can cheat them with less consequence. It's also that various parties in the arrangement can shift the burden of harvesting to their preference under the table. I'm not saying that anyone is wrong -- though my preference is that there be less waste -- but that there's something people prefer in having labor from away with different alliances. I'm not certain this is true, but in my particular experience it certainly was. To elaborate still further, I'm not saying this is necessarily wrong. The landowners still made out well, and they were earning profit without labor. The spilled berries went to the birds and insects. I'm just saying there was a non-obvious incentive for the overseers to hire people from away.
