Hey, founder here, thanks for checking us out. The demo video is a couple months old and since then we've gotten much closer to figuring out the best use cases after talking to users. Do you have any suggestions on the use cases you'd like to see the 'interesting features' put towards?

This is definitely the kind of product that takes several iterations to get right so thank you for following our journey.
I visited NYC two months ago for the first time—as someone who doesn’t drive it was incredible how pedestrian-driven the streets were. Cars would stop for me even when it was clearly their light.
They spent $2M on the demonstration plant, which is ~1/10th the size. It doesn't store the full 20 MWh. (Or is that 35 MWh? The article seems inconsistent on that.)

The bad news is, the capacity is lower, but the good news is the $2M is the cost to build the first prototype, and prototypes can be extremely expensive compared to the real manufacturing costs.

It seems like the only information available about the price is their estimate that they can hit $150/kWh.
Yep. HN used to spread more fake news.
Thinkpad P1 is looking pretty good.
My 100% unfounded, total wild guess is that a computer with 1 billion times the processing ability of current supercomputers could replicate the functionality of a biological honey bee brain.

From what I can tell though, I agree that there are alot of very subtle, but fundamental mistakes and omissions in both the design and combinations of current generation intelligence algorithms that are impeding a viable path toward general intelligence. Of course, if all we care about is dramatically increasing the efficiency of solving problems humans care about, this totally isn't a problem, because we apparently don't need general intelligence to do that.
Thank you! I'm an ex investment banker, so understand financials pretty well. I've also grown up helping with family businesses, doing the taxes from age 13 onwards, so it's sort of in my blood. I also wrote a little PHP toolkit so my parents could track inventories based on their invoices (that was 16 years ago!). That was probably the first version of Bx right there!

Despite everything I thought I knew, the project was significantly more challenging than I expected. Writing accounting software itself is conceptually not that hard, BUT, putting a scalable analytics framework around it is hard. Optimising queries to get the most of your metal is hard. Writing a PWA and making it feel native is hard. These are not obvious considerations when you think about writing accounting software, but take up a lot of time when you're faced with them during the development process.

Almost all the things I thought were minor considerations were actually very challenging projects in their own right. They were also excellent learning experiences.

And yes, the API is in fact now live, but only for corporate clients. We found most small businesses don't really need it, and some people even tried to game our rate limits, so we disabled it. We're releasing a new, more robust API very soon.

Also, now that we have some cash, we're also going to improve the landing page, add some tutorials, maybe even start a blog and do some marketing.

P.S. I never really involved an accountant for advice because I wanted to stay away from accounting jargon in the app. No journals or ledgers etc. Just simple terminology anyone can understand. I showed it to my accountant a couple of months ago, and he was actually very impressed. In fact, he's started using it with his clients to record their sales and purchase more efficiently. I can't really ask for a better seal of approval :)
The issue is not focusing on demographics, it’s excluding demographics. The law states you cannot exclude certain demographics. Facebook is allowing that.

Nothing is preventing an atheist from reading a Christian magazine, or some non-expected audience member from reading an ad targeted at a general audience. The problem is when you control the viewers on an individual level, as Facebook does.

My Debian Unstable laptop installation is over ten years old (and on its third laptop), and the packages are pretty recent, since Unstable is a rolling version.

And despite the name, it's pretty solid, I don't remember the last issue I had with it.
Lucid dreaming is dangerous. I used it to debug code - no shit. I've spent the last 15 years trying to err.. 'become normal' and sleep (again) err.. properly. Currently I do 2 sleeps per night with a 1-2hour break in between. One day I hope to sleep through a whole night. On the plus side sunrises......

Closures/blocks really make it a lot easier to follow the flow of async coding.

Async style enforces a kind of minimalism that in my opinion simplifies the problem space overall. Obviously, one has to learn different approaches to problem definition and solution to embrace event-driven coding.

To me, in the comparison of linear programming handling an exception when your call stack is 5 levels deep (or maybe 3 in a different use case), having to bubble the appropriate handling at each of those levels, versus async where in your closure you have a 4-line if/else construct that fires off one event for success and a different event for failure, async wins the simplicity competition every time.

If race conditions are an issue, events should be dispatched through a single-threaded finite state machine dispatcher for resolution. Such events can fire up multiple worker threads to do their bidding, but when state changes, that goes through the dispatcher which inherently resolves all races.
Must have been confused because you were complaining about insults directed at another user. How odd.
Yes, you could have 1 massive block, but the stresses and risks on the system would be much higher. Probably not achievable with current common tower cranes.

The beauty of this idea is that these tower cranes are standardised and ubiquitous. So it could be implemented immediately in almost any city in the world.
While I have a similar disillusion with the academia, I think sometimes people misinterpret the difficulty with reproducibility, especially on a field they are not familiar with. It seems to me it's imprudent and a bit disrespectful to jump to the gun when a certain research fail to get reproduced, especially when it comes to biology, because the experimental procedure can be incredibly complex and prone to all kinds of errors. I know of cases where even within a group only one person can successfully perform a certain protocol with a good enough success rate and it takes a lot of learning to get on their level. Without expertise in the field and knowledge of how the reproduction is done, it's really hard to examine all the data and judge the integrity of the science behind it.
To me the much bigger problem is how so much of the research is warped by what gets funding, fast.

$100 million here or there isn’t much of a concern when you’re that unprofitable.

What’s Uber going to do, shed their self-driving unit? Their only hope for profitability?
No. Because anyone can buy the WSJ and Teen Vogue and see the ad.

If you're excluded from being targeted by an FB ad you have no chance of seeing it. If that exclusion criteria forms the basis of a protected class and the ad in question relates to housing, that's illegal. So it's a very narrow set of behaviors that are wrong here, not all of ad targeting.

E.g. it's probably not illegal (or even morally wrong) to exclude someone who is interested in topics such as "Hinduism" from ads for beef jerky. Even though religion is a protected class, beef jerky isn't housing.

Similarly, it's (probably) not wrong to exclude low-income people from ads for your high-end condo because AFAIK income isn't a protected class.
Yup. Luckily i've got a friend who knows BIOS stuff like I could never do (Hi Greg) - nothing in there. Besides, it gets Fedora 28 installed and Windows is only used for doing firmware updates.

Which tbf Lenovo cocked up a couple of weeks ago and hosed the SSD firmware so it didn't boot. Luckily i'm not a moron so everything was backed up, they sent a new SSD and they picked up the old one to recover, which I assume will be a hardware firmware flash. I don't need the backup, but I am looking forward to Lenovo spending the money for the pickup/flash/delivery to make sure it costs them as much money as possible so they don't do this again.

>> Your conclusion does not follow from the premise (...)

Why not?
Is it not discrimination if there are 2 people reading the same catholic newspaper and one does not see the ad because she is female?
Anecdata:

I lost several dress sizes by eating things like organic beef. I have a medical condition that causes malabsorption. It is routinely treated with expensive prescription digestive enzymes, plus large amounts of prescription drugs.

I'm a former military wife. Technically, I should be able to get the $100k/year or more worth of medical treatment I am supposed to need for free, at taxpayer expense.

Eating right is vastly cheaper, saves all kinds of tax dollars and also gives me a hugely higher quality of life. Win/win/win.

Does anybody thank me for doing the right thing here? No. Instead, I am frequently attacked for any number of reasons, some of which seem to be rooted in this idea that poor people aren't entitled to eat well, and their health be damned.

You have no idea what that person's needs are. Being able to see that they weigh a lot and what they purchased on a particular day doesn't really give you enough information to know if they were spending wastefully on frivolous purchases or not on that day.
You sound awfully confident. This sort of distinction, where you declare something about the world to be certain as a consequence of a certain arbitrary categorization, I have an urge to call "nominative determinism" (although the phrase is generally used differently)
Chrome Mobile recognises this and suggests "simplified view" white background, black text.
Alright the interest has motivated me. I'll start posting episodically on joshleap.com as I jazz it up. Since I don't have a comment system people can give me stuff or validate my ego by email, it's a puzzle in my profile.
This again depends on a definition of "liberalism" accepted by all, but I find the term "illiberal" or "non-liberal democracy" (i.e. the opposite of a liberal democracy) to be very difficult to interpret. Is it a democracy in which people have the right to vote, but their liberties are not protected by the law? But- the right to vote is a liberty. And then again, how come people voted to have their liberties not protected by law? What are they, idiots?

In any case, I can't really recall any state etc that has gone down in history as being an "illiberal democracy"!
Redux isn’t a simplification of React context; it’s solving a different problem.

Context is the mechanism by which state is passed through to components. Redux solves management and lifecycle of that state as well.

Not a security issue but you're appending the PATH with LAMBDA_TASK_ROOT in the handler which is causing it to be appended over and over again with each execution. You can modify the PATH outside of the handler function so it's only done once.

Reservoirs are restricted in where they can be built, because water. And that real estate is in high demand for many other uses. I think it's a safe assumption that, in general, coastal properties (including those on lakes and rivers) are more than twice as valuable as inland property on average.
I don't get the point of having a veggie burger bleed. I tried an Impossible Burger a while ago and didn't find it that great. It doesn't taste like real meat and is just an average veggie burger. I think it's more of a gimmick.
Counterpoint: complaining publicly gets you attention from a big corporation, and as long as you don't seriously threaten the company, employees don't derive any animus from it.

My default belief is that any large corporation is populated by fairly normal people on average without a deep loyalty to their employer.
Let's start with our beloved Brian Wansink:

> "I don’t think I’ve ever done an interesting study where the data ‘came out’ the first time I looked at it,” he told her over email.

You could argue whole foods prices do prevent vast majority of ppl from going to whole foods.
The astronomy department I worked at briefly during my undergrad underwent a similar process. The ten or so grad students separately used Matlab, Mathematica, C, IDL, and a couple of the newer members used Python. They spent some time on the side working on the AstroPy package and all started transitioning to Python as their needed functions and data processing pipelines were implemented.

I'm in nuclear engineering now, I'm seeing a similar process. It used to be Matlab for everything but once the Anaconda Python distro came out and made installing python and the science libraries a simple process many undergrads are now using Python instead. The Spyder editor with the documentation window makes it really easy for undergrads to lookup functions, similar to the Matlab editor.
Historically, closed borders were associated with Socialist countries, like the USSR, that are generally not considered particularly democratic.

I think the engineering there is more difficult because you need very strong cabling and pulleys that can deal with huge load.

Those are pretty much guaranteed to go down the more people would use the service.

If you want to attract a lot of people, you will have to accept a lot of people, wether you consider their content crap or not.
MAC'D sounds like an interesting idea. If some of the options were healthy (perhaps you could pair mac'n'cheese with tomato soup) I could definitely see myself eating here.

I don’t buy this “what my time is worth” argument. Can you really say that if you weren’t watching a Netflix show, you would be working for pay? That assumes that (1) your sole leisure activity is Netflix, and (2) you can work 24 hours a day if you want to. It seems dubious at best.
I'm not sure it's that easy. The complaint dings Facebook for allowing targeting of ads by zip code. Isn't it the case in principle that people choose to live in certain areas? I don't think that discriminating on the basis of voluntary association that happens to correlate with protected group membership is enough to spare one from HUD's gaze.
I keep seeing people equate every hour they spend on X as the same amount of opportunity cost of they were working. Do you measure how much time you sleep, spend with your family, eating etc. in the same way?

I work 40-45 hours a week. Even when I am doing contract work, I limit the time I’m working. I don’t equate the 8 hours I spend working out to lost wages either.
The problem is total exclusion, not targeting for sub-groups by campaign. If they wanted to target sub-groups by campaign, they could offer a service to advertise differently to different subgroups. But that’s not at all what’s happening - this is an exclusion of some subgroups, where the only feasible reason for their exclusion is their demographic, rather than the good/service being sold or the type of advertisement.
I concur with this sentiment. I was just doing the hiring loop and came to the conclusion that taking CSPA would have been a total waste of my time. I don’t know how many companies would value the data after looking at the example questions, but I almost find it to be a good signal that I shouldn’t apply to companies that use it.

A standardized assessment is literally the farthest thing from what happens in real world programming. In contrast, the Triplebyte interview questions focus heavily on what an engineer actually does day to day. When I completed Triplebyte, I was pleasantly surprised at how well orientated the assessment was. CSPA just looked plain insane in comparison.

Even the time commitments are a good contrast. Triplebyte’s commitment on the quiz side is about 30 minutes, and the final interview is a couple hours. CSPA is five hours.
I've had several impossible burgers and they completely live up to the hype. They taste very good indeed. But I have noticed a slight uptick in anxiety after eating them, maybe 30 mins after or so. This anxiety comes out of the blue, the first few burgers I had, I had zero health or safety thoughts in my mind that might have precipitated the anxiety. Interested if anyone else has had a similar experience.
This study's definition of low carb diet doesn't reach ketosis though.

I do want a proper study on a keto diet, on one hand it's an unnatural biochemical process for the majority of non-starving humanity, on the other hand there seems to be no downside to ketosis under than the Flu in the short term.
Cheers, thank you too!

Pricing is hard :/ Price too low, and people don't take it seriously. (e.g. $9 for 35 hours of video). Price too high and people run away. It was my first product, too. I looked at it as, "how many hours would this save someone?" Filtering through bad tutorials, just-in-time googling, all that stuff. Of course with front end there are a billion other learning resources out there, lots free, lots cheap. Hopefully the book is a more direct path than some of those others. Always room for improvement and experimentation of course :)
Yes, Facebook should commit civil disobedience by explicitly allowing housing ads to not be shown to black people. Great plan.
That seems like a poor argument for why it should be illegal, since facebook ads are not limited to housing and employment.

The analogous argument for knives would be "In the context of torture knives don't have any legal uses. (So knife sellers need to put safe guards in preventing their knives from torturing people)".
Sounds like a great idea. You should build it!
Given what we know of the NSA's success at pwning much of the Internet, this is an incredibly ironic piece of propaganda.

Indeed, I can't help but agree somewhat with Xi Jinping:

> Finally, China has promoted “cyber-sovereignty” as an organizing principle of Internet governance, in direct opposition to U.S. support for a global, open Internet. In Xi’s words, cyber-sovereignty represents “the right of individual countries to independently choose their own path of cyber development, model of cyber regulation and Internet public policies, and participate in international cyberspace governance on an equal footing.” China envisions a world of national Internets, with government control justified by the sovereign rights of states. It also wants to weaken the bottom-up, private-sector-led model of Internet governance championed by the United States and its allies, a model Beijing sees as dominated by Western technology companies and civil society organizations. Chinese policymakers believe they would have a larger say in regulating information technology and defining the global rules for cyberspace if the UN played a larger role in Internet governance. All four of Beijing’s priorities require China to act aggressively to shape cyberspace at home and on the global stage.

I mean, Brazil and other countries are pursuing "cyber-sovereignty". The EU's GDPR is fundamentally that. As is Google's latest undersea cable.

I have always loved the cypherpunk vision of a sovereign Internet. But that's very different from a US-dominated Internet, which is what we've had since the start.
"The company’s self-driving unit continues to be a drain on cash"

Uber should not have a self-driving unit. Self driving cars are only going to be safe to use on infrastructure specifically made and certified for self driving cars. That's going to take massive government investment that probably isn't going to come any time soon. You're only going to see self driving cars in say intentionally created smart cities any time soon.
Thanks very much for this information (you and @grhmc).

PLEASE consider releasing some form of this tool, or at least documenting the snot out of it... it looks incredible. We'd really use this at work.
The fact that fraud has been found out can mean two things:

1) That the system works so well that the only time fraud has occurred it has been found out

2) That the system works very poorly and this is the only time fraud has been found out
Regardless of where you stand on the issue, there is no analogue in traditional (read: newspaper) advertising.

If you take out an advertisement in a Catholic newspaper, you're focusing on Catholics. But non-Catholics may still read your advertisement if they come upon your newspaper. There is no method in traditional physical media to specifically exclude any demographic; there are only ways to emphasize one demographic over another. This makes digital advertising with demographic-based exclusion (rather than demographic-based inclusion) incomparable to a newspaper.

That difference may seem hollow but it is a difference of category, rather than degree. More important than this point is the observation that these kinds of debates quickly devolve into litigating the appropriateness of imperfect analogies rather than the original issue itself.
There’s a risk that people will start using context everywhere as a minor convenience. This is the reason the React devs kept the original API so obscure.

I try and limit context to the things that are used across the app, but are not coupled to a given component. For example the user’s session, environment specific behaviour, or theme information.
So quick to call BS without knowing what you're talking about. Transit spectroscopy is a well established scientific method. To put it simply... obviously they accounted for that.

No. Because a preference for organic food isn't a protected class.
Thank you for the perspective.
