If we attach our installation to an existing reservoir, we'll take up nearly zero land above ground. If we build a new self-contained upper reservoir it will be about 0.5 miles on each side and 40 feet deep. It can be built with material excavated from the lower reservoir. This may seem large, but it's for a huge amount of storage 20GWh - enough to balance the load of a large city. And keep in mind that it's about the same size of the many large reservoirs that are scattered around a large city.

Again, the most promising option would be to simply attach our installation to an existing reservoir. We don't use any additional water, we just borrow it. For an ample sized reservoir, each cycle would just raise and lower the water level by an inch or so. Another promising option is that we can even use the ocean as an upper reservoir. Salt water can be accommodated -- See our notes about the Okinawa Yanbaru Station.

There are more details in our white paper posted on the website.

Hi Manuel, thanks for the comment. I reached out a few times to support and never heard back. It does look like most of my issues were quietly resolved later, but we ended up abandoning the dashboard and using the API directly for a lot of tasks. If I'm being honest, I don't have a lot of confidence in Mender's reliability due to those experiences. However, it's mender-convert's limited device list that is really driving the search for an alternative.

There are utility-scale solar installation options that use no concrete at all. Steel earth anchors support the frames on which the modules are mounted.

The low capacity factor (it's actually around 30% for new solar and 50+% for wind) is already accounted for in the levelized cost of energy. LCOE from renewables is a factor of 3-4x lower than from new nuclear.

You speak as though Wayland is some super new bleeding-edge tech that just needs some time to come around, but the reality is that it is over 10 years old and still people revert to X11 to get things done because of its issues.

Compared to when Windows overhauled its entire display server, network, and sound driver architecture back in Vista, Wayland's pace is downright glacial. I suppose one can expect it will be ready for prime time by 2030, just in time for the next paradigm to make it obsolete.

Probably not. Facts aren't copyrightable but creative works are.

So prices on Amazon.com are facts. User reviews are creative so probably copyrighted.

This makes a lot of sense. Sacrificing a percent of profit from other funds won't make that much of a different in the minds of possible investors, but managing a fantastically high fund must be a good advertisement.

Not criticizing at all, genuinely curious: what do you want to accomplish on an iPad that is prevented by the walled garden?
It's unavoidable that if you get almost all of your power from some source, but demand varies, you will have a lower capacity factor for that source, unless you have utility-scale power. France does indeed have to curtail nuclear power plant output, because they get almost all their electrical power from nukes, and they don't have big enough resistors to burn up the excess electrical energy that would be produced otherwise. The US has a higher nuclear capacity factor because it gets most of its power from other sources.

> This characteristic is called being dispatchable.

While I mostly appreciate your contributions to this conversation as being informative, a dispatchable plant is one that you can turn on and off to respond to demand, not one that cannot be higher than the wind itself.

I'm not sure how accurate this tactical liquidity picture is, at least for much of medallion's history. For a good portion of their existence they called in all their trades twice a day. Them being fairly late to the automated trading game was one of the the surprises from the book for me. Any "HFT" as mentioned in the article is not done by renaissance, but through execution services.

The big picture seems to be statistical arbitrage done with extreme precision and leveraged to a massive scale. Add in some quasi-legal agreements with banks, and likely tax-fraud, they are able to do this at a magnitude no one else can.
I don't think they could keep it up for that long without slipping up at least once. Enron started around the same time and got tripped up in 2001.

If it were a one man investment shop, then maybe it leans more towards fraud. But if they obviously employ dozens of quants, and have obvious hardware outlays, it seems less likely.

It makes a lot of sense to me that they just win a bit more than they lose, play a lot of hands, and treat everything with pretty even money, so they're never overexposed in any one place.
Maybe, but I don't think we really know what a "good" global economic contraction will look like, or what behaviors will come with it. Although, it seems pretty obvious that gas-powered vehicles will become a rarity, and (I hope!) working from home becomes the norm, not the exception. (That last one seems like such an obvious change we could encourage NOW.)

I wonder if the number of stars are copyrighted. It's not creative, but a fact.
Native apps are generally a lot easier to scrape since they rely on an API which can't be changed willy nilly without breaking compatibility with older apps. Also you can't do captcha etc on API calls in the same way you can on websites. And of course the data is neatly formatted to be machine readable.
There's some huge datasets of Amazon reviews available. Stanford has a big scrape out there, plus there's one from Amazon themselves in the AWS datasets.

I’m building a highly customized, web-based inspection data and quality management system at a medical device/aerospace manufacturer that is essentially replacing a lot of old VB code, with some additional stuff.

Having previously worked at a marketing company and a startup, it’s been fascinating to experience a legacy manufacturing company growing (or trying to grow) into the future.

Yes, the engineering problems are fun and all, but I think the most fascinating part has been thinking about what American manufacturing will look like 5, 10, 20 years down the road.

In my experiences, I believe American manufacturers will NEED to invest in industry 4.0 tech in order to mitigate costs associated with rising wages, shortages of skilled machinist labor, and greater demand from consumers/regulators/OEMs for information and transparency.

I’ve also been quite amazed at how much paper is still used and the lack of industrial software products with quality UX.

And I don’t think American manufacturing will ever cease to exist.

The fact that they have information about apps that I specifically chose to not link to facebook for variety of reasons...

Including one specific app that they have 356 interactions from that I really do not want associated with my facebook account.

Looks like I am going to be spending the next couple of days digging through the report I just generated.

When this is all server side is the only option to make an email that is only for facebook and hope they can't link data any other way?

You're referring to survivorship bias and yes, that's a factor. But while there was a fair amount of garbage topping the charts when I was a teenager, there was also a fair bit of great songs as well. For a variety of reasons, the selection process of what becomes a chart-topping "hit" has changed, and I think that is part of the problem. The biggest factor is that the business side of the industry has virtually perfected cramming what they want into our ears until we like it - or at least until they make money off it. In the past, society as a whole mostly selected the winners through tuning into radio stations, buying albums, etc. The nature of the business has changed dramatically over the decades where now people just pay for streaming services which for all but a few artists never come close to replacing the income they would have had via the older methods. The industry execs have also gotten really great at manufacturing pop hits through people like Max Martin (and the other guy who's just like him) who crank out similar/familiar songs with the same structure over and over so people like it because it feels like they already know it and it's so close to something else they already "approve" of in their brain. It's the music industry equivalent of how social media hijacks your dopamine system.

If we were to build reactors to replace existing fossil fuel plans there would not be enough uranium cheap enough that it makes sense to use it.
Godot has been a breath of fresh air for me lately (been running master branch for a while) and I know that it is going to only get better. I can't wait for the vulkan renderer to be ready, I think it's going to a game changer for godot.

After Epic originally promised to make linux a first class citizen, I went all in ue4, but they lied and went back on all those promises, and I have since moved to a completely open source gamedev pipeline and I think it's the future.

For example, think about how much mods make or break game longetivity and communities. If valve hadnt given us world hammer, there would be no counterstrike, no tf2, no garrys mod, no age of chivalry and ergo no chivalry medieval warfare. The residual effects of modding capabilities are huge, and having formats that are easy to work with with normal tooling (like gltf) mean open source gaming in a game engine like godot (or a few others, armory3d is another) could be a sleeping giant just in the early stages of waking.
Match backs? Or offline conversions? Looks like Zapier offers a match back service too.
I'm building a new general purpose RPC mechanism to replace the current HTTP/REST technology, as well as the whole TCP port thing. What service you're talking to on the host will be completely hidden from prying eyes, and unblockable.

You call an endpoint anywhere on the planet and give the name of the service you want, which then gives you access to that service's published API (similar to how you'd use import and gain access to a library's API).

To start, it will operate over port 80/443 to allow seamless integration into the current world infrastructure, but I'm also hoping that in maybe 10 years it could replace HTTPS entirely, possibly even TCP.

The first step is an encoding mechanism that supports the most common data types natively, which I've defined here [1], and am currently writing implementations for in go. It's a parallel text and binary encoding so that we don't waste so much time generating bloated text that's just going to be machine-parsed at the other end, but also allows converting on-demand to a text format that humans can read/write. I ended up developing new encoding schemes for floating point values [2] and dates [3] to use in the binary format.

The next layer above that is a generic streaming protocol [4], which can operate on top of anything from i2c to full-on HTTP(S), and supports encryption. It's designed to be as non-chatty as possible so that for many applications, you simply open the connection and start talking without even waiting for the other side's acknowledgement. It supports bi-directional asynchronous message sending with chunking and optional acknowledgement on a per-message basis, with tuneable, negotiable message header size.

The final layer will be the RPC implementation itself. I want this as a thin layer on top of streamux because many of the projects I have in mind don't need full-on RPC. This part is still only in my head, but if I've designed the lower layers correctly, it should be pretty thin.

There is not turn-off at all. If you read carefully you will see that they will still collect the data, just that they "promise" won't assign it to you. Yeah right :)
I always thought scraping was a fun idea, I just couldn't find the right use-case for it. I'm not a sports guy, and the big sites have pretty extensive API's. Something music related would be of interest to me, but I can already get updates on events like concerts (since the monopolies make a fortune selling tickets). I'm not sure what could be useful.
I think any ruling that says LinkedIn can't put in protectionary measures against automated requests is doomed to be overturned, as long as they're not doing it discriminately. Captcha, rate limiting, user agent testing, etc are all common tools to protect against malicious/unintentional denials of service. The question is what was LinkedIn doing, and did it specifically target hiQ while permitting others of the same class of traffic.

I had followed a guide in ~2010 to delete my account (since the magic incantations to delete your account at that point were really obscure). I was told via email that my account would be deleted a certain amount of time (90 days IIRC); I got curious in 2015 and logged back in. I was not terribly surprised to find that I could log back into the account and all my old data was still there. They may actually delete accounts now, but this certainly hasn't always been true.

Many are only looking at solar panels in term of greenhouse gas emission in the production chain, while any kind of semiconductor processing will have a lot of chemical waste occuring.

Edit: Also, recycling solar panels isn't sraightforward at all because of heavy metals (e.g. Cadmium) being used as dopants.
'Correct' language is determined by usage. If something is commonly used by a group of language speakers, that is the correct usage within that language. If you want to be really pedantic you can say that it forms a particular dialect, just as teenagers in school and presenters at an academic conference may both speak very different but equally correct forms of English within their dialects

I think you mean contradiction, not paradox.
Can you provide a link to that evidence please? The claim that there were no elevated levels of radioactivity agrees with what Met Ed and public officials were incorrectly announcing at the time, but contradicts what Wikipedia cites NRC historian Samuel Walker as writing in "Three Mile Island: A Nuclear Crisis in Historical Perspective".

Dickenson College is 30 miles or so from TMI, while Mt. Wolf is a few miles away, and from the ranch the cooling towers loomed clearly visibly on the horizon.

https://www.google.com/maps/dir/Mount+Wolf,+PA,+USA/Dickinso...

Do you have any doubts that the power company and public officials were terribly prepared for the disaster, and lied to the press and public (as was also true with Chernobyl and Fukushima), and that is a much bigger continuing problem for nuclear power's reputation than Jane Fonda ever was?

https://en.wikipedia.org/wiki/Three_Mile_Island_accident#Eme...

>The uncertainty of operators at the plant was reflected in fragmentary, ambiguous, or contradictory statements made by Met Ed to government agencies and to the press, particularly about the possibility and severity of off-site radioactivity releases. Scranton held a press conference in which he was reassuring, yet confusing, about this possibility, stating that though there had been a "small release of radiation...no increase in normal radiation levels" had been detected. These were contradicted by another official, and by statements from Met Ed, who both claimed that no radioactivity had been released. In fact, readings from instruments at the plant and off-site detectors had detected radioactivity releases, albeit at levels that were unlikely to threaten public health as long as they were temporary, and providing that containment of the then highly contaminated reactor was maintained.

>Angry that Met Ed had not informed them before conducting a steam venting from the plant, and convinced that the company was downplaying the severity of the accident, state officials turned to the NRC. After receiving word of the accident from Met Ed, the NRC had activated its emergency response headquarters in Bethesda, Maryland and sent staff members to Three Mile Island. NRC chairman Joseph Hendrie and commissioner Victor Gilinsky initially viewed the accident, in the words of NRC historian Samuel Walker, as a "cause for concern but not alarm". Gilinsky briefed reporters and members of Congress on the situation and informed White House staff, and at 10:00 a.m. met with two other commissioners. However, the NRC faced the same problems in obtaining accurate information as the state, and was further hampered by being organizationally ill-prepared to deal with emergencies, as it lacked a clear command structure and did not have the authority either to tell the utility what to do, or to order an evacuation of the local area.

>Fire would have allowed Neanderthals to cook those animals, making the meat easier to chew and more nutritious.

I understand fire/cooking may make meat more bio available to humans (I suppose it is also possible to make meat/food more nutritious, or at least chemically alter certain enzymes making the food arguably more nutritious in certain instances)...but can we really apply human digestion broadly to neanderthals?

Is it not possible Neanderthals were better equipped to digest and/or absorb calories/nutrients from uncooked meat/food generally? Anyone know of differences in modern human and modern monkey/chimp/ape digestive systems?

RenTec does use a lot of leverage, but they only can do it because there Sharpe ratio ((return-riskfree)/volatility) is over 7x. This means that if there fund had a unlevered return of 3.5% then their vol would be 0.5%. Let’s say their risk limit is to cap vol at 10%, this means that their theoretical return would be 70%. It doesn’t exactly work like this because of volatility drag. If you’re interested check out my blog post on the topic: https://smabie.github.io/posts/2019/10/04/vol.html
