> In the 1950s, physicist Léon Brillouin published a landmark paper refuting the idea that adding a single diode, a one-way electrical gate, to a circuit is the solution to harvesting energy from Brownian motion. Knowing this, Thibado's group built their circuit with two diodes for converting AC into a direct current (DC). With the diodes in opposition allowing the current to flow both ways, they provide separate paths through the circuit, producing a pulsing DC current that performs work on a load resistor.

> Additionally, they discovered that their design increased the amount of power delivered. "We also found that the on-off, switch-like behavior of the diodes actually amplifies the power delivered, rather than reducing it, as previously thought," said Thibado. "The rate of change in resistance provided by the diodes adds an extra factor to the power."

> The team used a relatively new field of physics to prove the diodes increased the circuit's power. "In proving this power enhancement, we drew from the emergent field of stochastic thermodynamics and extended the nearly century-old, celebrated theory of Nyquist," said coauthor Pradeep Kumar, associate professor of physics and coauthor.

> According to Kumar, the graphene and circuit share a symbiotic relationship. Though the thermal environment is performing work on the load resistor, the graphene and circuit are at the same temperature and heat does not flow between the two.

> That's an important distinction, said Thibado, because a temperature difference between the graphene and circuit, in a circuit producing power, would contradict the second law of thermodynamics. "This means that the second law of thermodynamics is not violated, nor is there any need to argue that 'Maxwell's Demon' is separating hot and cold electrons," Thibado said.

There's no such thing as "American Job", jut like there's no such thing as a New York job or LA job. Jobs are a product of a market, that can be as local as a building or as global as information services.

American Dream cannot exist in a world with limited resources. It only existed in a rapidly expanding resource pool - taking lands from natives, creating new tech, freeing up resources by killing millions of people or digging up stuff from the ground.

As such - it's not CEOs job to maintain your job, specially when those CEOs are pushed by your own pension fund managers to move your job somewhere more efficient.

And finally - global poverty has dropped significantly because of that outsourcing. Ignoring that is literally being the "they toork R jerbs" South Park charachter.

Two-thirds of people who file for bankruptcy cite medical issues as a key contributor to their financial downfall.
While the high cost of health care has historically been a trigger for bankruptcy filings, the research shows that the implementation of the Affordable Care Act has not improved things.
What most people do not realize, according to one researcher, is that their health insurance may not be enough to protect them.
The prime example of that is the Azure Portal. I am an occasional user for simple things. And the portal looks like a B747 cockpit to me
Hopefully these can be sandwiched below solar panels to harvest thermal energy from the gradient.
> how many of those people get invasive treatments for things which would not have actually become problems?

That's really the doctor's issue to address, not the device's. Sticking your head in the sand isn't the right solution to the problems of dealing with information too aggressively.

> They've backed away from screening as aggressively for certain cancers because the risks of aggressive treatment turned out to be significant and it turned out that more people than expected had tumors which didn't develop into a problem before they died of something else.

Literally the only way to build viable metrics for which tumors will develop into problems is for _everyone_ get screened, not for no one to get screened. The problem of treating too aggressively is a treatment problem, not a measurement problem. If we avoid measuring, we have no way to learn how to treat better.

If we decide to never look because we don't yet know how to handle the information, then we will never know how to handle the information.
Doesn't Singapore run on $1/hr workers from other countries? It has much higher inequality than Japan.
I had covid and at least my experience was very different. When I have a cold, I get stuffy and lose my sense of smell a little bit. With covid, it wasn't stuffiness... just couldn't smell, period. This remained after all other symptoms cleared up and I otherwise felt just fine.

When it happens, you KNOW you have covid.
There is a tipping point where my flexibility becomes your complexity. As you say, it’s hard to get right. It’s also hard to know when you got it wrong, since customers overwhelmed by the complexity will choose another product, while power-users clamor for more “flexibility.”
All of the aspects of generational inequality stem from a single root cause: the rising dependency ratio after the peak of the demographic dividend. US labor force participation peaked in the 90s as female entrance into the workforce peaked. After that happened, the countervailing force of lower birthrates began to take over and the dependency ratio started to rise.

We're all fighting for a piece of a pie that is, relative to the population, shrinking. And it's shrinking because of demographic trends that began decades ago and would take decades to reverse.

Every developed country is going through the same thing, and some are in much worse positions than the US. Older people were lucky enough to be born into a world with demographics favorable to growth; younger people are unlucky to have been born into a shrinking world.

I mostly ate spicy food during my time with it due to the fact the physical sensation of spiciness being one of the only things that made food interesting. Same with saltiness. I actually ate a lot less during that period due to not having much drive to do so with a lack of taste.

I find a lot of her work to be repetitive but that's true of a lot of artists. Having said that, some of her work is reminiscent of realist painters like Edward Hopper and I really enjoy it.
4x speedup at batch size 1 is really terrible. GPUs are terrible at small batch sizes. And that is comparing a research project with production hardware.

Honestly if you look at any of the other AI hardware startups they all advertise much more significant speedups.
It is a good start!

I look at the first paper as generating a hypothesis. That's the first step in any scientific process. A few replications later, we've got a theory, and then a few more later, a fact. The first papers are as important as the rest of that pipeline.

What causes outright harm is:

1) Papers with poor methodology;

2) Authors overselling their results; or just as often

3) Readers / reporters giving too much confidence in preliminary results

To be clear, I was calling em500 on #3, not the authors on #1 or #2.

On a skim, I don't see obvious problems (but, then, I wouldn't expect to find them; most require a deep read). It's published in an open access venue, which is always a good sign. It also helps that you're from BC, which for the most part, (still) has a pretty good reputation for scientific integrity (there's been a rapid decline in scientific integrity over the past two decades, and that's hit the institutional culture across the river from you particularly hard).

So you're okay by me!
No. Everyone.
I was disappointed how Gitbook, after going the SaaS way with v3, has broken compatibility with their own v2 cli. If you export markdown files from gitbook.io, gitbook-cli v2 is unable to import them and turn into static HTML files because Gitbook now uses custom liquid tags which are not open-source.
I had COVID and the loss of smell lasted for 3 days. But it was a complete loss, like, down to 0%. In my wife's case it lasted for a week and returned gradually over the following week.

As a European, I find it weird seeing how polarized the entire political system of the USA is. It looks almost like there are 2 religions that do not like each other on all levels.
I think politics should be about making laws that make society a better place, but with a two party system only one can have the majority and thus it evens looks undemocratic to me.
Thanks. This is helpful
This is quite a bit more than "a single Docker container" though, isn't it? This is networking, SSL cert, traffic routing, secret management and a whole CI pipleline.

Of course it's looking complicated "for a single container", but if you wanted to deploy your app in a traditional server setup, the graph would look the same, if not worse.
Large-Scale Distributed Reinforcement Learning with Menger

Larry Williams, a professor at UC Davis did a lot of work on this. He found that canes are not a significant contributor to vine nutrient status. Only 2% of the nitrogen that falls to the ground in canes ends up back in the vine the next year.
Under some circumstances, I sympathise a lot with users who are trying to do their jobs, identify a tool that will help them to do their jobs, and then get told "no" by IT, particularly if IT is being obstructive for no apparent reason except throwing its weight around.

However, when you're talking about something like external hosting and transferring data outside of your organisation, I think there is a line that has to be drawn, partly just as a responsible corporate citizen and partly because of the potential liability when laws and regulations such as those you mentioned attempt to mandate that sort of responsible behaviour.

In an obviously sensitive field like finance, healthcare or law, bypassing the rules and setting up shadow IT really should be a serious disciplinary matter, possibly even a firing offence. It is, after all, potentially causing the company to break the law, not to mention creating severe security and privacy risks, and the damage that can be done by a small group or even a single individual can be catastrophic.

I feel like UNIX tools do this very well.

Setting aside the random naming and inconsistent argument placing, most UNIX CLI tools have sensible default behavior.

But you can man the tool and find a whole bunch of switches etc that offer up a lot of complexity.

The piping system similarly is brilliant. It’s a simple and easy way to make extremely complex workflows using simple tools, but you could spend your entire life never knowing about piping and still do just fine with the individual tools.

All this has happened before, and will happen again.

The reason should be that developers develop along as simple and as standardised a means as they can, so that what they're working on will be consumable by as many people now, and in future as they can be.

Sure, I'm of the 0.001% of people on the planet that could easily spend a half hour going through the console and working out why on Earth their content isn't displaying to me… but this is a .org (.uk) - their remit is to be open and to Do The Right Thing.

Almost 100% of their users are not the sort that should be expected to dissect their website to work out where they've gone wrong.

Again, this isn't anything complicated - it should just be HTML spat out. That's it. Nothing fancy.
Do you have a source for ads accounting for $10-30 of the final price? I'd be curious to learn more about this.
I just tried to use it via the Java API (using the dockerized memgraph and neo4j driver, as indicated in your page), but there seems to be some SSL issues (self-signed certs). If I disable the SSL when running memgraph, it seems to connect, but the neo4j driver complains about it being an "unknown server". These checks are present in the newer neo4j drivers.

Is the Java API supposed to be used with an older neo4j driver?
I guess a ~10kohm resistor in series couldn't hurt, should something go wrong. After all your finger is not exactly super conductive in the first place...
I see a solution with individual auditing.

I want to see my social graph across different proprietary data stores and either charge a dime for use of my data, or reclaim a node.

Auth is one issue, building that graph is another, and hiding data from regulators is the last I can think of right now.

Regardless, the sentiment remains.

When I write this comment, it's work. I made some content for y'all. But if a scraper comes through and builds a social profile of me, it should compensated or controllable in some form.

I wasn't selling this data, but it's not really anyone else's data to sell either. Even if ycomb decides they are going to sell this information, I'd like to know that.

IDK what the solution is. It's probably reclaiming ownership via private servers. It's probably grand trust and code contracts. It's probably even a mandated anonymity filter where PII is opt-in by default and only a certain degree of information can be traded.

I am just under the impression that there has been a massive overreach and that the majority of people online have lost control.
Hawaii is reliant on the mainland US for the bulk of its food imports AFAIK, not a global network.

It’s also in an insanely strategically valuable position.

If shipping between the mainland US and Hawaii has stopped for a month, US aircraft carriers have been sunk. Nuclear weapons have most likely been used.

You’ve absolutely got a point here about the fragility built into the current system, it just doesn’t nearly apply as much to Hawaii due to other factors.
Attacks Aimed at Disrupting the Trickbot Botnet
It would be better to use a software TOTP authenticator with backups. You could also store multiple encrypted copies of the TOTP secret encrypted with different Yubikeys. I don't know if there's any software that does this automatically and momentarily decrypts the TOTP secret into a secure memory location when you need it. That preserves... most of the benefit of 2fa.
Yeah, I think that's unusual. I assume most people lose their smell a bit when their nose gets stuffy, but complete loss... no.
I love how you are exposing the cognitive dissonance between too many people for the economy/world and immigrants do not depress wages. How can someone hold these two views simultaneously are they not the same, just at a different scale?

Airbnb | Remote (preferably West Coast) or San Francisco, CA | Senior Staff/Staff Software Engineer | Full-Time | airbnb.com

My team (Cloud Infrastructure) is hiring for a staff and a senior staff level software engineer to focus on our internal platform as a service built upon Kubernetes. Over the last three years, this has progressed from a pilot project to running almost all of our production services at immense scale.

Besides Kubernetes, we are in the process of rolling Istio out, and use Terraform, AWS and Chef extensively. Our team mostly uses Golang but it helps to have familiarity with (or a lack of fear of) Java and Ruby, which most of our product teams use.

Airbnb has a large number of engineers and users, which creates interesting technical and organisational challenges.

The job opening for senior staff engineer is here (and a staff posting will follow soon): https://careers.airbnb.com/positions/2245198/

Note that these positions are for highly experienced engineers and it helps if you have 8+ years of experience and/or have acted in a similar capacity in prior roles.

Please send me a brief note and resume at sunil.shah@airbnb.com or apply online.

Hero of labor was a rare award, only given out 20812 times (according to Wikipedia); I'd be surprised if less than 20k Americans received a bonus on any given week under the current status quo.

Please remember that I was responding to a comment, not making an abstract statement that communists never give out awards. The grandparent had said that it would be good if communists and socialists were more generous with awards than capitalists, and I was making the case that it would be antithetical to the typical communist ideology.
With cold and flu you loose your smell because your nose is stuffed up, and it's more of a diminished smell than total loss.

With COVID, your nose is clear and there is just no smell at all.
Ask HN: Anyone else miss spontaneous conversations at work?
Considering it's been 6 months since most office workers have started WFH, this is a question I've been thinking on.

Of course, remote work has many benefits such as cutting down on commute times, being able to work at your own schedule, and less office distractions. But one thing I find sorely lacking & so far irreplaceable is the spontaneous interactions that used to happen. You know, water cooler talk, catching up with a friend you run into, side conversations before a meeting etc.

I was toying around with the idea of an app that can help you "bump into" your coworkers again, but only when you're on break & want to chat. I was curious if people even had this problem in the first place?
Excel has an entire ETL engine called PowerQuery tucked up under the hood. Originally part of SQL Server Analysis Services, it got strapped into Excel about a decade ago, and more recently tons of other products[1].

The Web[2] connector is what you're after. It can consume a variety of formats, including csv, xml, and json. It supports HTTP Basic Auth pretty well, but if you want to put the data source behind oauth it can get tricky (it technically supports it but depends on how novel the implementation is).

Credentials sit with the (Excel) client, so if the file gets shared with a new user it'll prompt them for authentication details when they first attempt to refresh it. It'd be pretty easy to set up a template/turnkey workbook you can just hand over to new clients with everything all set up and all they have to do is enter their credentials when prompted. Only caveat is Excel for Mac - it only gained Power Query about a year ago, and porting it over is a very involved[3] process including an entire .NET Core rewrite and factoring out Windows dependencies from legacy cruft. The Web connector is one of the many that haven't made it over to the Mac yet, so any clients using a Mac would still need an alternative.

You might like to read about Cuba’s agricultural crisis after the collapse of the USSR, and how quickly they were able to adapt, despite being an isolated island nation. It might give you more confidence to pursure your dream to move to Hawaii!

Before 1991, Cuban agriculture was heavily based on cash crops and relied on subsidized Soviet oil. The collapse had severe effects and caused a famine, made worse by state interference. Despite all this, the ability of the people to quickly adapt away from industrial agriculture to organic and urban farming saved them from mass starvation. It’s an inspiring story of human adaptability through the most difficult of times.

> Thanks for the C-star link. At first glance shapes look similar to what have become launch dimensions. I think it'd be pretty interesting to hear a comparison from someone who's used both C-star and CUDA, about the plusses and minuses of each... have you used both?

Nope. I'm looking at C-Star through a historical lens, I was curious at the overall development of CUDA and was researching the "line of influence", so to speak.

> Right; I'm saying the "SIMT" of 10 years ago has to do with masking and maybe other per-thread control (even though the Connection Machines might have had it as well), and that per-thread counters are now going beyond what we used to know as SIMT, perhaps deserving of some other acronym. Or maybe SIMT is becoming more appropriate and more differentiated from SIMD over time? Is it possible that CM5 should be called SIMT and we simply didn't have that acronym at the time?

CM2 was just another SIMD machine, there were plenty of others before CM2 (its just that CM2 was one of the more popular ones). IIRC, Cray had similar SIMD machines that competed against them. The overall SIMD-methodology reaches back until the 70s at least, maybe earlier.

Just noting that CM5 was MIMD at the lowest level, trying to correct a mistake I made a few posts back.

------------

I think what "happened" was that Intel adopted SWAR: "SIMD With A Register" when Intel created the MMX / SSE / AVX instruction sets. (compared to dedicated SIMD-computers like the CM-2).

At some point, Intel's SWAR approach became colloquially known as SIMD (even though SWAR was much more limited compared to "proper" SIMD computers like the CM2). NVidia creates a new acronym called SIMT to differentiate Intel's SIMD (aka: SWAR) from a proper SIMD machine, even though the 80s-style SIMD was substantially similar to NVidia's new SIMT term.
