Depends on the tradeoff. The tl;dr of the article is that there's a tradeoff between pressure and efficiency. You can store at higher pressures in smaller vessels, but it's much less efficient. Low pressure (larger vessels) can be extremely efficient. In between, there are hacks to increase efficiency using heat exchangers and the like.

Beyond that, this is being pushed in the article as a rural/off-grid approach. For urban residential, it makes a lot more sense to centralize storage and run houses off a regular grid, than to try to make each house an independent entity.

In the medium run, we need to shift the grid itself from the current baseline+peak model to a solar+storage model (rolling wind into this), with distributed metering on the storage grid. Capture solar/wind power when the sun shines and the wind blows, and sell it when consumption outstrips supply, with pricing set dynamically on a distributed network.

Once you have that, for on-grid purposes, we'll probably see a diverse world of storage - car batteries, compressed air, industrial battery sites, water storage, thermal storage, etc.

Honestly it sounds like a developer (or group of developers) through together an app that appeals to creepers and they felt arbitrarily singled out for creating a blatantly creepy app whereas the ones that quietly monetize the same data (via data brokers or something to that effect) get a free pass.

Ordinarily, a developer would bugger off but they (presumably) have alt-right activist leanings and they're trying to make a mountain out of a molehill. Check 4chan on any day and there will be "FB/IG creep" threads where users anonymously upload photos of their female Facebook and Instagram friends in skimpy/swimwear clothing.

Afaik, compressed air energy startups come and go since long time, this should be ok for use in enterprise though.
Because I don't believe in stealing other peoples' things just because they have them. And because I want to make sure that I am free to dispose of my property as I see fit and allow my children to reap the benefits of my labor, and the labor of the generations that have come before them, clawing our way up off of rock farms in northern New England to something better.
Couldn't this be done at scale to create more and more samples to make the system more robust to noise?
I know because, staggeringly, there has been actual research done and I talk to human beings who this affects. Like, literally five seconds on Google Scholar could have answered that question.

Do you have counter-studies to cite, or is just a case of academic consensus not agreeing with you and so being ignored? I'm actually astonished by your responses here. You're writing with an air of superiority and authority while asking basic questions like "Who are these people?" and "How do you know they exist?" which I had assumed were fundamental bases of any legitimate discussion on the topic.
And you're referring to what you can physically do with your own vehicle after you buy it. To my knowledge that has absolutely nothing to do with software copyright law. I don't understand your basis for arguing that software's copyright can be used to infringe other rights.

For example can my water heater's manufacturer ban me from washing my dog in the bath because they own copyright on the software in the thermostat micro-controller?

If Tesla were going to provide liability insurance, I could absolutely see them having the ability to limit usage (under that insurance). But software copyright is an unusual argument.
I think I would like to open a university department in my city - or a museum of contemporary art.

But I have NO IDEA of how much money is needed for that. $25mm seems so astronomically high

I googled: $145 million is the MoMA yearly budget. For a little museum in a peripheral town $25mm seems appropriate.

If people is willing to invest $25mm please contact me, I have big ideas now :P
Personally that seems like a better alternative to the PR downplay of engineering accomplishments to make space for the praise and glory of managers and funders.

Right. I thought it would be interesting to see it there were experimental findings on a large scale. For example put a massive solar array in the US SW. Transport the power across the country and store excess in geologically stable areas. Those storage facilities then act as power plants at night or if there were delays in sunlight.

> both foobar2000 and Chrome/Electron use ffmpeg for audio processing and codec support

not quite true. for example, the ZXTune plugin brings support for a dozen of chiptune formats which is obviously out of scope of ffmpeg. It'll be possible to incorporate webaudio api for codec but that's a resource hog. Also if you're doing decoding work and the GC jitters, you're going to run out of audio buffer (stuttering). If we take one step back and rely on some audio playback API, then gapless play and other issues would be difficult to deal with.

> The web audio api allows for writing all sorts of equalizers and audio processing effects.

maybe, but that's reinventing the wheel. foobar2000 supports VST plugins, the professional tools used in the audio production industry. there are a few dsp components for webaudio but that's far from satisfactory.

> Extensions and query and library management can be coded in JS easily, like VSCode, Hyper and others do.

Yes I agree. That way we can make a neat package manager for an audio system. Some Digital Audio Workstations(DAW) have already begun to move this way (Bitwig Studio etc.)

> for every little interaction will lead to a huge mess of performance and latency issues.

Not quite sure.. Think about how NeoVim is built. But my concern is that, foobar2000 is not built for tightly interacting with a frontend, so yeah, better rebuild a native audio core, and use a modern communication protocol (msgpack maybe?) to do the roundtripping. But again, that protocol could be implemented as a foobar2000 plugin...

The downside of using foobar2000 is also obvious. It's close sourced and Win32 dependent. So I'd think about this:

```

Electron frontend <-- msgpack --> Native audio core <--> JackAudio, RtAudio or alike, whatever that bypasses the middleware and directly access the hardware audio buffer

```
Only tangentially related, but the second image in the article [1] — the one with all the cameras right in Zuckerberg's face — is crazy. What a strange and surreal experience that must be.

I just sold my Alexa for a Google Home. My experience can be summarized by this.

Me: "Hey Alexa, what's the weather?"

Alexa: gives the full weather report

Me: "Hey Alexa, what's the high today?"

Alexa: gives the full weather report

Me: "Hey Alexa, is it supposed to be sunny today?"

Alexa: gives full weather report

Me: "Hey Google, what's the high today?"

Google: "The high temperature in your location is predicted to be 82"

Me: "Hey Google, is it going to rain today?"

Google: "No, it's not forecasted to rain."

I've had an Alexa for over a year now and it's never changed or gotten "smarter" towards any of my questions. Eventually I just gave up and switched.

Very easy to use components between JS react and ReasonML react. Docs describe this process well. As for the bucklescript macros, the most frequent ones are easy to get used to. bs.raw is a very last resort macro that is almost never used.

Highly recommend giving ReasonML a try.

Intel was using a ring too until their most recent architecture. Sometimes multiple intersecting rings when the number of cores grew too large.
As a bit of a meta point, I find it really distracting when authors make random sentences bold. What you believe to be important is not necessarily what I'll find important, and the added emphasis breaks my flow.
ppx (like `[%bs.raw ...`) are indeed tricky. They mostly seem to be used around the FFI. My experience has been that if you're going to use JS components from within Reason, you just type the portions of the JS interface that you'll actually use, and that's pretty much always a subset.

When you're outside the FFI, the language really shines in build speed and output. Support of ES Modules out of the box is nice too.
Most states have a no texting and driving law, or even that you can't be holding your phone while driving laws in place. Would that still be valid if the car is driving itself? I'm guessing at least right now it would still be illegal. Does anyone here know?

The correct way to handle this is to leave the option of retaining history up to the user. Most users want to look up what they have asked before. https://www.google.com/amp/bgr.com/2016/06/01/google-home-in...

As others have pointed out, Tesla's failure in the EV market won't do much damage as it really isn't the big player and their poor execution is only handing money to competitors. Worse for Tesla they have already given time for established brands to enter and or announce their own EVs. Many people are waiting for their preferred brand of car to come with an EV option.

What the real threat is the damage to self driving that Tesla gives the public. After a series of very publicized crashes where Tesla handled their response poorly journalist are looking at every Tesla crash for involvement of their Autopilot software. Every crash is under suspicion. That alone is a hole that Tesla is going to have a hard time crawling out of and it combined with other companies missteps it will only keep setting back the field.
Oh yeah, I didn’t do anything on the Internet in 1990 apart from typing ‘go internet’ into CIX (my BBS at the time), sitting there wondering what you could do with it, then killing the connection when my dad pointed out that we paid by the minute for the phone line :) I don’t think I knew anyone online that wasn’t on CIX either.

> I don't like the idea of Tim Cook going to BMW just because he drives and likes BMW however... I think it's a bad way to make decisions.

No, I think that's OP and you reading too much in that tidbit. The original quote was this:

BMW was long Apple’s top choice, given its focus on
high-end but mainstream products, former employees said.
Many Apple executives, including the company’s chief executive,
Timothy D. Cook, also drive BMWs.

So BMW was a top choice not because many execs are driving them but because it's a luxury premium auto brand and sells quite well - which is very similar to Apple brand consumer electronics.

Also, Jony Ive is a car guy, he loves Aston Martins, Bentleys, Saabs and Land Rovers and have a huge collections of them. By your logic, it'd be a "bad choice" to consider Aston Martin simply because Jony Ive loves them :)
Inside the animal internet
tl;dr: under GDPR terms, anything is "personally identifiable" if you have the means to resolve it.

Technically, writing "John Smith" on a piece of paper can become anonymous data if there's no way to determine who wrote it and it doesn't mean anything to anyone who has access to the piece of paper (because there's a lot of people with that name or because they don't know anyone by that name) but of course names should be treated as personally identifiable to be on the safe side.

On the other end of the spectrum a vague description like "that chubby guy with the crew cut" can be personally identifiable information if you know who it refers to, even if someone else might see it and have no idea who you mean.

So the exact lines are highly contextual and pseudonymisation does not guarantee anonymisation: if you call a Rose by any other name, you still know it's her you're talking about.
That is great, so you should be able to somewhat relate! I think we should just all have a little more empathy. There is a lot of hate going around and somewhat like in the tech systems many of us work on daily, even problems that seem simple are very difficult in complex systems. Countries, the US in particular, are very complex systems and the issues that are imposed on those moving around western nations are not simple to navigate. I'm not a visible minority, but i still ran into many roadblocks, I'd hate to be easily singled out visually or have a language barrier, and have to deal with the issues I had to deal with.
The charge/discharge efficiency for compressed air is terrible since most of the energy gets wasted as heat. This plus the terrible volumetric energy storage density makes it a nonstarter for most applications.
The Kroger in my area already has two options for this. When you walk in, you can choose a 2 person box that is all ready to go. They normally have 2-3 options available. The other option is more akin to the frozen meals-ready-to-heat (like those from Bertolli). These are stored in a frozen case where you have 8-10 different options. You can get a pre-measured serving or mix/match by the pound.

Granted, this is a very new store in the Kroger home of Cincinnati and used for a lot of testing, but it's something they have been working on.

The problem for these bigger companies is that they are big companies. What works for large, urban markets doesn't work for their more rural stores. So finding the mix of services can be hard, especially when you don't have the floor space to devote to new products. Also, integrating these types of products into your existing distribution network can be a challenge.

I've been impressed though by how much these companies still do try to innovate in response to competition. For example, when Amazon bought Whole Foods and opened up Prime delivery of groceries in our area, Kroger within weeks started to offer their own 2-hour delivery service. But again, this isn't a service that would be practical to offer across their entire footprint.

Free business idea: A store dedicated to exactly this.

Imagine instead of many different, individually packaged, products, you have one (or maybe a handful) of pre-packaged meals for one or two people. The retail space and checkout would be insanely efficient as you'd just grab and go.

You'd have the green angle too as there wouldn't be any excess packaging to keep the food fresh nor carbon emissions from all the individual deliveries. Just standard refrigerators and pictures of happy patrons walking home with their meal kits.

The recurring subscription model, i.e. the holy grail of high valuations, could be added as well. Either through the usual $X/period gets you Y meals or maybe just a discount ($Z/month to get Q% off).

Or taking it to the next level, imagine a meal kit vending machine. The owner would stock it each day (say around 3pm) and customers could grab their own meals with a quick swipe of their card. Same idea as the store but reducing the retail space from a mini store to a couple square feet.

I must admit, even as a critic of the GDPR in some respects, as an individual I am hoping that its heavy-handed approach will mean I can buy everyday things again without having spyware, telemetry, and so on coming as standard. I don't want a "smart" phone or a "smart" TV or a "connected" car, where the scare quotes denote entirely unnecessary invasion of privacy and/or security and safety risks. I buy a phone to communicate, a TV to watch stuff, and a car to get from A to B, and it will be nice if we can get back to doing those things better instead of tacking on all the user-hostile extras.

We need fundamental changes in the generic message that "value added for society" is better for you, for everyone.

Wealth is passing, wealth is relative; once your real, true needs (not the ones you think you need) are covered, we, indeed, should be focusing on moving humanity ahead, and not on personal hoarding.

When my wifes replies to questions like what is your dream house like? as a tiny, self-sustaning house, so I don't have to do housework, she regularly meets confused looks, because "but what about space and and large space and...".

Focus on what you really need, not on what society tells you to believe.

Reducing platform dependence seems to have removed a great deal of the barrier of consumer adoption of desktop Linux. I see more people all the time trying to figure out how to get it running on their MBPs, trying to understand differences in desktop environments, and how to dual-boot. Browsers on Linux support DRM for viewing popular services like Netflix, and native graphics stack development is improving more rapidly all the time.

VFIO with LookingGlass has been great for people who work on Linux and game on Windows, and I think that paves the way for a very interesting future. Perhaps one day we'll see a Windows Gaming container that just does a useful thing without trying to steal the show.

Also, FOSS acceptance is so commonplace now that we no longer notice its pervasiveness. Try to find a software or service that doesn't have an open source clause or a succeeding software company that totally eschews it. It might not be front and center in the marketing, but open source is as essential an ingredient in today's development as public access to books is to a more equally literate society.

> No idea how it works in the UK, haven't had consumer-grade fibre here yet, always just got business-grade stuff where you bring your own hardware & UPS if needed.

I've installed (business) fibre links on 6 continents, handoff has always been a pair of fibres (usually LC or SC), usually with a /30 ipv4/ethernet, and a routed network pointing at my end of the handoff (or in the case of private peering, a BGP configuration)

My FTTH from BT is a single fibre (no idea if it's compatible with generic bidirectional sfps). This runs into an Openreach converter box - powered by a battery backup - which has 2 phone outputs and 4 rj45s.

My core mikrotik plugs into one of the rj45s and establishes a pppoe session with BT's network.
