The claim that Uber drivers aren't actually earning money but just engaging in "conversion of stored value in their vehicle into short-term earnings" is based on a clearly flawed study [0]. Even after subtracting out vehicle wear and tear, drivers make a modest (but not great) wage. You can rail about "exploitation" and "starvation wages" but the people I know who have worked for Uber generally thought the wage was decent and the conditions were better than most alternatives. Removing the option to "be exploited" by Uber doesn't leave them working a cushy 6-figure software job; it leads to doing work they like less.

Those are slightly more esoteric/unusual programs. More common would be Computer Science.

Yep, the public university program could definitely use work, no argument there. But I’m under the impression that most states have at least one serviceable university.
It strains credulity to believe that Intel wasn't aware that they were trading side-channel resistance for performance. The problems are just too deep and pervasive. None of AMD, ARM, Power, or SPARC came close to the number and severity of issues in Intel chips. There were problems in those chips, but their nature and limited scope shows that everybody had a rough idea about how far they could go before they made privilege separation worthless from a confidentiality perspective. Yes, some went a little too far, but it seems clear that Intel just said, "f-it", and stood on the gas pedal.

Hyperthreading/SMT is a trickier issue because it had obvious and even proven side-channel potential from the beginning. But 1) everybody had to hold their nose in order to compete with Intel on SMT performance, and 2) technically the operating system communities should have made the effort to keep unrelated processes from sharing an SMT'd core. And that still needs to happen--we need smarter schedulers.
I think new uses and new users will continue to abound, so I don't think humans will radically reduce their consumption.

One evidence of this is just the sheer number of cars on the road these days. Human population is increasing, and an abundance of cheap ICE cars means everyone is driving to work at least in suburban areas. In the past, busses and bikes were selected because cars weren't economical for certain individuals.

Now nearly everyone at our office drives a car by themselves to work. No more car pooling, biking, ubering, bus, train, walking, etc.
In my view theft is the same contractor or not. Both has an obligation to the company providing the work. I agree that a happy employee is less likely to try to steal customers but, the ethics gets a bit muddy for some. In those cases (in my own experience) the threat of a big stick is often enough. This applies to any business that puts trust in it's workers to handle customers or customer information.

With respect to your "enough value" statement, I understand. It also requires regular reminders about the level of service the customer gets from the company, not the individual. But that can't be all. Seriously, lots of businesses are like this. They need to trust their team to hold up their side of the basic work agreement.

Take a bar for example. If the bartender starts skimming cash through one of the various means, that's clear theft and depending on the amount, can be a felony. The threat of getting caught might be enough for most but, it still happens. It's messy dealing with people and we unfortunately need to do things that protect the company.

I'm not sure what valuation and funding have to do with a business model. Walmart looses more than 300mil in in theft per year. Should they be looking to get out of retail? This is just one problem every business has to deal with in one way or another.

Don’t forget pedestrian behaviors that make bad driver behavior more deadly.

I started keeping score of pedestrians walking into a poorly placed pole on a corner outside of my office. Since June we are up to 48. We convinced our landlord to put a potted tree in front of it, which helped, but the local SeeClickFix community reported it and had it removed as potted plants are code violations.

Watch a busy street sometime. People do funny shit, like walk into traffic without looking or wandering into buildings while using the phone.

Why would having a person classified as an employee turn it into a full time job? Like why would they hire managers and set schedules when it gives no benifit to Uber?

To me this closes a loophole. As you say these people drive for Uber, uber is doing the employing. This is not like if a contracted a builder to renovate my kitchen. That is the class of employment that are real contractors.
Drive a stick shift in america and you'll very quickly see how many people are zombies behind the wheel. Red light means head down phone time. People run red lights way more often because they either didn't make the green because someone was on their phone at the start of the line and people are too scared to use their horn and risk road rage, or they themselves were head down. The police do not enforce the laws on the books about distracted driving or driving while texting, hell the police don't respond to much any more in our city unless you say active shooter. It's just so frustrating to try to drive any more in the past 10 years because of phones.
A little story of admission of evidence I heard from a friend of my wife when I gave her ride home recently.

We listened to Sirius 117 thru our ride and they always tell crime stories. It was a death row story and when the narrator said that the only evidence they had against a suspect was a DNA but it was enough to put him on electric chair, she chuckled a little. It was odd so I asked her why. As a court reporter she witnessed many horrors written by life, but this one was particularly scary for another reason. She was reporting on a case where the only evidence of a murder was a DNA, even though a suspect was in New York on a day where victim was murdered in Los Angeles. The DA rested case explaining that DNA evidence is enough and holds up in courts for many years and that they do not need to explain anything else, how he go from NY to LA at the night of murder or really nothing else mattered "because of DNA." So defended lawyers ran a suspect DNA via one of popular DNA-kit websites and to their surprise they found a good enough match. She was lucky to be called in when the case was heard again (most of the time different court reporter would be called in depending of availability) and they showed that result to DA/prosecutors asking if they would consider prosecuting based on that person DNA. They look at it and said it was the same person DNA. So defended lawyers revealed that it was different person. To judge shock, then DA came to say that DNA match doesn't have to be 100% and over the span of human existence some 100 billion people lived so its quite possible for extremely similar DNA to be found in wild. She recalls looking at judge face at that moment and he turned pale blue - you couldn't help to see this man wondering if over the span of last 2 decades, he may have sentenced hundreds of people based on inadequate evidence. The case did not ended there but shortly after when she was checking on it, the whole case all of sudden got sealed and even year later was still locked down. All she knows is that most likely he wasn't found guilty, as checking on his name recently did not yield any record on Cali's death row list.

So so much of DNA being of 100% proof.
This is really interesting! As someone who lives in the desert, I would want one of these.

But nothing comes for free - it seems like the output would be dependent on the humidity level of the air. If everyone was running these, would it be as effective? My gut says yes, just due to how much airmass there is, and even the heat from the ground should provide some mixing. But I am not sure of the napkin calculation, which I'm sure they've done.

Also at higher temperatures, the air can hold _more_ water vapor. This is why humidity is relative to the maximum amount of water the air can hold.

The CO2 capture potential is also really impressive.

That's a ridiculously narrow view of what democratic representation means. Is it still democratic representation when some people are barred from voting for no good reason? Subjected to undue burdens or intimidation? Is it still democratic representation when some people's votes count for less, either because of gerrymandering or because of extra seats in the senate and electoral college for thinly populated states? Is it still democratic representation when we can't verify that our voting systems are secure, but can verify that one party is doing everything they can to block improvement? How bad do these distortions have to get before we conclude that we're no more "democratic" than the old USSR? They had elections too, so it's all good, right?

The solution is to update laws that reflect the future (ie, giving contractors better rights and better temporary unemployment social support) instead of protecting entrenched dying industries and their working hour/payment models, by forcing their business models to be the only one allowed.

You also don't have to defend Uber directly, this type of stuff will affect the whole market including any future or present companies that are far better run than Uber.

If you look at reviews for the old taxi companies in most cities they are all 1/5 stars. Plus they aren't shining beacons of worker protections or good pay either. Most taxi drivers were already contractors before Uber so I'm curious how these laws will affect them too.

>“For a given capital outlay on oil and renewables, how much useful energy at the wheel do we get? Our analysis indicates that for the same capital outlay today, new wind and solar-energy projects in tandem with battery electric vehicles will produce six to seven times more useful energy at the wheels than will oil at $60 per barrel for gasoline powered light-duty vehicles, and three to four times more than will oil at $60 per barrel for light-duty vehicles running on diesel,”

If these figures are even in the rough ballpark of being correct, then it is all over bar the shouting.

Petrochemicals are still an important component of industrial agriculture needed for feeding 7 billion people around the world.

If oil prices fall too low, Persian Gulf and Russian borders become unstable and from there its any ones guess, how things would take shape.

Energy is heavily interlinked with geo-politics and if Persian Gulf is out of the game even for few months - millions of people will starve to death. The only silver lining is that North America is self-sufficient in ONG for the coming years, and that is not the case for much or Europe, Asia and Africa.

Here the software side of the fad rears its head: there are about four dozen microservices involved, each with its own RDS instance, load balancer, the works. 5-6 different implementation languages were used and a large number depend on the JVM or other memory-hungry runtimes. There are a couple of so-called "data analysts" who don't really know what they're doing, never produce anything, and spend lots of money on EMR et al. Buzzwords abound.

The workload is containerized and orchestrated (of course, since a company so self-conscious about its tech fashions would never not be) but one can only increase the density so far, and obviously optimizing the infrastructure spend on "sexy cloud stuff" hasn't been the top priority.

Even hinting that hardware may be appropriate for a certain use case will bring out the bean counters in force. At a third company, I almost gave the "Global VP of Cloud Computing" an aneurysm by suggesting that there may be a use for some of the tens of millions of dollars of hardware that they'd recently purchased. In shock and disbelief, he shouted "What, now you're talking hybrid cloud?!" I said "if that's what you want to call it" as the rest of the room jumped to inform me that the R&D departments at the cloud providers ensure customers will always be using the latest datacenter technology, hastening to add that Microsoft is building a datacenter underwater somewhere, and thus it's a lost cause for anyone to run their own hardware. Some of the shadier cronies in the room chimed in to add that the hardwareless course of action had been confirmed as the ideal by both IBM and Accenture in studies commissioned by the VP.

Cloud resources are a useful tool in the toolbox, but as an industry, we have gone way overboard and lost all reason. At some point, when cloud inevitably loses its shine, the bubble must pop. If you're in the market for server hardware, this is a great time to buy.
"Supported by a solar panel to power a fan and heater, which speed the cycles, the device produces up to 1.3 liters of water per kilogram of MOF per day from desert air."

This is pretty good, but not yet amazing. It's more energy efficient than a compressor-based dehumidifier, but probably still less efficient than trucking water in from somewhere a few hundred miles away where it's plentiful.

Either way, the big question to me is how well it will hold up over hundreds of cycles - there's no report here that I see on whether or not the MOF will also trap dust particles and other things that are likely to decrease efficiency over time.
Linux had more bleeding edge development, and that's what developers wanted, so that's what they wrote their apps for, and so that's what people used for workstations, so that's what got all the newest hardware drivers, and new kernel features, and new desktop work, etc etc.

Linux just had "more stuff". Without any other particular reason to pick one over the other, most people picked the one with "more stuff". Nobody wanted to install an OS for a server just to find out it couldn't run the latest software, or didn't have the latest drivers. In addition, the userland of the BSDs was different from GNU tools; if you were already installing GNU tools on every other OS you adminned, you might as well run the OS that's based on it. Finally, if you wanted Enterprise support, Linux was the only Open Source choice, afaik.

Some at the timed claimed performance benefits from one or the other, but various benchmarks showed Linux and BSDs each had their respective performance strengths that could generally be overcome by tweaking.

I gave a Prius a love tap today while riding my bike. They pulled right into the bicycle crossing without looking and then continued to only look the other way for an opening in traffic to pull out. So I stopped, got off my bike, tapped on their door a couple times to make sure they knew they were blocking the bike lane, and then went around.

Pretty much any time I can tap on a vehicle that is pulled into the bike lane or cross walk I do just to let them know that they are driving poorly. Not anything that will leave a mark, just enough to get their attention. I usually end up doing this two to four times a week.

Most of the time it seems to me that the offending drivers are in pretty poor physical shape. So I've just kind of chalked their driving behavior to be due to their lack of experience using the bike trails and sidewalks.

This is interesting but I am curious about some of the implications. I am under the impression that migrations encompass more than schema changes. It may require data transformations, index rebuilds, or updates to related tables. I would agree that these things are preferably avoided, but in practice it seems that they happen frequently.

I viewed the author as targeting smaller dev shops who don't have a dedicated DBA/expert. Groups who might use an ORM's migration framework for example. In which case, it would appear that there is significant loss in migration flexibility if you remove application code from the architecture.
The current scenario is that you can turn the app on and do work any time you want to do it. If you are an hourly-paid employee, you can't just choose the times that suit you, because it might not suit what's going on at that time. You can't just drive where you want, because it might not suit what's going on. So the only solution is going to be something like what you usually think of for employed work. Set hours and times etc.
I started receiving these a few weeks ago :( I thought it must have been an exploit somewhere.
I don't disagree with you. The product is new and we've put a lot of effort in trying to create good logos but we're by no means perfect. The idea is to let users use it for a couple of months. If they like their logos, they buy them. If they don't, that is feedback for us and we can use that to significantly improve our models. And I believe that the logos might not be perfect but some of them are usually pretty good. You can have a look at our twitter page to see some good examples:

Ride-level data and per-trip fees are also a requirement in New York City. In fact, now minimum wages are required in New York for TNC drivers. The point still stands, is that Uber has never, and would not ever, actually threaten to leave bigger markets. And the data isn't some evil hoovering scheme, but it is incredibly helpful with city planning:

If the cost of extracting it is too high, it stays in the ground. Otherwise, it gets used as a precursor for higher value products like plastics.

The caloric value of a hydrocarbon is approximately the minimum price it can be sold for. Almost any other use will give higher returns to justify paying a higher price. Though hopefully it doesn't just mean more plastic everything, that would be disappointing.

this largely fits with my experience in Seattle. congestion is so bad that police have flat out said they won't enforce traffic rules like "blocking the box" [0]. first, compared to e.g. Austin, the fine is laughably cheap (Seattle $136, Austin ~$500). second, i'm all for police having leeway, but not in such a blanket manner. there's a reason we separate powers, and they don't get to decide the rules. finally, it isn't just blocking the box, it's also things like "no turn on red". so while bad drivers are getting away with more and more, it's gotten quite dangerous for pedestrians and cyclists.

> Last year, he formed a company called Water Harvesting that this fall plans to release a microwave-size device able to provide up to 8 liters per day. The company promises a scaled-up version next year that will produce 22,500 liters per day, enough to supply a small village. “We’re making water mobile,” Yaghi says. “It’s like taking a wired phone and making a wireless phone.”

Any ballpark estimates on the cost for a residential use unit? i.e. 200L-1000L/day

Also, is it feasible for this to markedly effect downstream areas?

i.e. If there's eastwardly wind flowing through Nevada where machines are extracting humidity at an extreme scale, how might the 30%+ humidity-requiring plants (i.e. that Jamaican Yerba) in Utah hold up?
