We don't need to store everything.

We just need to store enough to make load-shifting environmentally (and commercially) available. The 30 Gigawatt Hour Bath County Station gets there (https://en.wikipedia.org/wiki/Bath_County_Pumped_Storage_Sta...), but even the "smaller" Tesla 50MWhr projects do too.

Compressed Air is hitting 300MW-hr designs (https://www.greentechmedia.com/articles/read/texas-calls-for...). That's enough for a metropolitan solar community to loadshift the 12:00 noon sun to the 5:00 dusk peak-energy period. (Average home: 30kwhr per day. 300MW-hr design would serve over 10,000 homes easily, and doesn't need to actually hold the electric usage for the whole day. It'd realistically only need to hold 1/10th the energy or so, to load-shift a few hours here and there).

ARES seems to be in the 12MW-hr to 100MW-hr design size. This is smaller than Pumped Hydro but still useful. Smaller, cheaper projects that partially solve the problem is still a good thing.

It seems like a perfectly good solution to the problem. Buying up cheap energy from night (or noon-power solar arrays), and selling it during the 3pm to 7pm peak-energy time. As long as there's at least a 20% differential in peak pricing somewhere in the day, "small" 1MW-hr to 300MW-hr plants will be profitable.

----------

In any case: Wind continues to work at night. Nuclear works throughout the day. Hydro works throughout the day. We don't need to store EVERYTHING, we just need to store the excess from Solar from noon, and then load-shift it to 5pm to 8pm, while the sun is setting and solar arrays generate less electricity.

It's not going to work, because instead of giving the people skills and confidence to negotiate, they're just going to leave the industry because they feel unwelcome.
Just needs a better experiment, on a sample body larger than the current one.

If only there was an environment where we could test the behaviours of people faced with repetitive, "will draining" tasks who would also be willing to participate in long term studies.

Something like, say, an MMO. Especially one where the scientific community was already involved and protocols for interaction had already been established.
Could you clarify? I don't understand the extreme reaction.

I was responding to this: "hold both views simultaneously: to respect someone and consider him/her an extremist loon who is out of touch with reality"

I gave an example of someone generally considered to be an extremist loon, yet obviously (he did in fact gain power) with unusual skill.

Is it just that people are uncomfortable with the idea that his supporters were normal regular supposedly civilized people, and how this implies something about most of us?
I think doing things right is the way to change the image. Surely it's easier to trash your image than fix it, but with time I don't see why it can't happen.

The examples of refunds provided for Neus Q and Revolv are a good example of the company trying to do what's right, and I'm sure that helps the image a little bit.

Plus at least for the onHub they do provide email and phone support. https://support.google.com/onhub/answer/6270180
After posting the above comment I was thinking that, if I mentioned 'free-app' as a differentiate, I should say something about revenue generation; even if going the non-profit route, charitable donations may provide enough cash flow.

How to pursue this idea without charging patients is still a problem I am trying to solve. Here are two ideas I have:

1. If we are able to ethically collect anonymous data for use in research; institutions could pay a subscription for the data (This seems more suited to a non-profit company)

2. With the increase in use of mobile applications in patient care and research, this app could be put out for free as a promotional tool for a company that specializes in creating mobile software for medical research.

I have my instances of Node-Red running on :

1. Home IoT controller
2. Public-facing webserver
3. At friend's house where my 3d printers are

And they are all connected together via Tor for networking. Hidden Services are awesome, as they can semantically be treated as a huge ethernet hub (topologically speaking). And Node-Red can command and control other Node-Reds via other plugins.

Edit: There's 474 different Nodes that Node-Red can use. And one node is node-red-contrib-npm, which exposes any npm module as a node to Node-Red. Which sums that up to about 250,000 nodes. http://flows.nodered.org/

>Do animals have mental states?

beside being just a religious dogma of "only humans have soul" in disguise, answering "No" would mean that the one can suggest a specific plausible place in a continuous chain of living organisms from any human back to first cell (or just to say first mammals) where the "soul" ("mental states") supposedly magically appeared. I mean did Neanderthals had soul? Did Australopithecus? Did the apes 2M years ago?

I used to be jealous about Americans and such for being able to not to have to worry about US visas and get paid a lot. Then it occurred to me that I can just go to Switzerland or any other European country as I have a Euro passport. Then the jealousy went away! ;) Currently in the US on a student visa. Idea was to go the H1B route, but that way seems annoying.
There was an Acura ad recently which said the car would change your route if it knew there was a jam ahead.

"Why you shouldn't /rely/ on exercise to lose weight" would be a less controversial title. Instead they chose a provocative, click-baity title and tone to the article.

The most accurate title would be "Don't exercise in order to earn the right to eat junk food later". Which is the meager point they're actually making.

The article deserves all the criticism - it has been designed specifically to provoke it. Journalists love to divide ho-hum issues into polarized opposing sides.
I do have an EU-passport, but I do not know what an HN-handle is.
I'm arguing that talented people move to greener pastures when they feel that they are undervalued or not treated equally. If for every overachiever you have x number of people who go "well I'm going to get paid the same as long as I put in my 40", you will no longer have a successful company. If you doubt the existence of this, you will have proven that you have never worked for the government.

> A better approach is offer the over-achievers a promotion. New position, new responsibilities perhaps, and a new salary. Attainable equally by anyone else who wants it.

I don't see how this is any different from offering pay raises. What if there is no room for advancement in the company? How do you measure whether people qualify for this? You can always offer more pay, you aren't necessarily able to create new job responsibilities and titles out of thing air.
>the expectation that every autistic person

People seem to accept stereotypes when they're positive.
When driving I've also noticed another phenomenon. When reaching the crest of a hill there's an optical illusion that cars are bunched together. From this viewpoint the driver can see more of the road and vehicles ahead. My theory is that this causes a momentary shock or panic, and it often causes drivers to slam on the brakes, causing ripples of braking behind them.
Well, the title was changed, which makes this somewhat silly.
I sort of wish he'd write a new edition of Applied Cryptography. I learned so much from that book in the 90s, but so much has changed since then.

It's modular arithmetic because of the internals of the processor, not because of some law-of-the-universe.

It could just as easy a processor not allow over- or under- flow operations. However, it's easiest to just truncate the number and essentially do modular arithmetic. That's the difference. Over- or under- flow, checked, wrap-around all refer to the state at which the operation's answer needs more space than it is given. Modular arithmetic and checked instructions are what to do in those situations.

Aside, division in modular arithmetic can be done, but it's not what most people want (hence why usually not performed). 4 / 3 mod 7 -> 4 * 5 mod 7 ( 5 is the multiplicative inverse of 3 mod 7 ( 3 * 5 = 1 mod 7) -> 6 mod 7
I typically go with a related argument:
"Productivity" is measured in the value of capital transferred during interactions, not utility produced from interactions.
The Pomodoro Technique allows you to get into the flow faster by providing a structure that allows you to ignore distractions and complications.

It meshes exceptionally well with Neil Fiore's "The Now Habit".

I'd love to compare more notes with everyone about deploying to ECS.

If you want to play with an ECS cluster, `convox install` is a free and open source tool that sets everything up in minutes. Little to no AWS knowledge required. https://convox.com/docs/overview/
ECS is order of magnitude more complex than almost anything I had experienced with (taking out Marathon).

I found ElasticBeanstalk to me MUCH simpler for Docker based deployments. It's using ECS behind the scenes for multi-container instance.

You essentially deploy a zip with with a Dockerrun.json metadata file and it handles everything for you, including rolling deploys based on your auto scaling groups.

I never found the ECS definitions of Task and the rest really intuitive to work with.
I do agree with the feeling that doing exercise makes you feel better, and that this feelings motivates you to eat better food.

I don't see how you say you simply can not agree with the article tho.

The article stipulates that exercise itself has less effect than diet. Maybe exercise helps to keep a good diet, but exercise + keeping same crapy diet won't be as effective as what you did yourself.
These are maximal efforts that are not sustainable for any period of time.

Meanwhile, you can do 150W on a bike all day, just keep adding CHO.
Interesting. I was running pfsense since 2006 on a P4 box with PCI Intel pro NICs + WRT54G on DD-WRT, then on an AMD Geode-based HP thin client with an expansion board to give it PCI-E to use a Pro1000/MT card + Cisco Aironet 1200 from eBay that someone flashed LWAP FW onto and couldn't fix so they sold it as parts/not working ($50 IIRC, had to track down the right firmware, took a day of messing with it), and finally now an ERLite + Airport Express + Ubiquiti AP AC Pro.

Power usage on the P4 sucked (>100w idle). The eBay thin clients did much better, usually around 20-40w, and the ERLite is lowest (and it's fanless). I ran a Cisco 2651XM for a while before any of this, but it maxed out doing NAT slower than my home connection was. Honestly though, I was just super excited to get something off-the-shelf for $100 that was stable, supported, low-power, and didn't require much administration. Messing with this stuff was a fun hobby and I learned a lot, but now I don't have as much time and it just needs to work.
Well that's scary as all fuck! I didn't realise NGOs were as susceptible to this sort of thing as commercial enterprises. I guess I was being naive and should have known better.

Thanks for the insights.
> HN always has very extreme, and usually very negative reactions to any kind of tracking, integration, promotion, analytics, etc - and rightly so, with governments and corporations eroding our privacy at every step, we have to be on guard.

My understanding of this phenomenon is that only people with extreme views comment. I mean HN is filled with slack, apple, github, google etc fanboys. None of these are opensource and they all track users.
The concern is that if the site is insecure you might send Geolocation which might be sensible information through unsecure channels allowing someone to snoop on the connection and read that data.

In other words they are trying to hide the geolocation data from proxies, Carriers, ISPs and someone possibly MitM attacks
Yeah. There's something to be said for having a highly developed intelligence for building great IDEs and libraries at the _organization level_ rather than just at the individual programmer level. Despite its reputation for hiring the very best programmers in the world, Google's ability to create a really great developer toolchain for Android didn't measure up to what Microsoft has been doing for decades.

It seems like Google has tried to pursue a cheap shortcut to IDE greatness, at first by building a plugin for Eclipse, and then, by putting some money into a relationship with IntelliJ and Gradle (who truly are excellent at what they do).

But still, Google has not brought the excellence of organization and deep commitment fully in-house.
Your comment would make sense if CS is all they talked about during the interview, but it's actually only a small portion of the total process--an hour or less.
Yes but most hardware startups have a single product and will put their entire companies effort towards keeping things going. If Google gets bored with a project you can kiss it goodbye.
The remote update "feature" means this has a built-in backdoor into your local network. So you don't want to install this in a law office, anywhere that has to be HIPAA compliant, or any environment requiring security.

I do have some sympathy for the author, but it's a good idea to keep in mind that just because nobody ever told you there was a rule against getting sloppy and working outside normal business hours, doesn't mean it's a good idea to do so. Having a passionate argument for why your problem is someone else's fault, is nowhere near as good as not having the problem in the first place.
"You shouldn't even want to accelerate immediately at the same rate as the car in front of you,... but that doesn't mean we can actually do that without tons of collisions."

That is correct. Therefore, safe driving will actually create traffic waves. It seems unlikely we'd actually want the regulations that would prevent this sort of wave!

I didn't get the impression that she wanted a safe space, just that she was criticizing design decisions.

"The problem is that you can't prevent a stranger from sending you something you don't like"

Sure, but Instagram could choose not to automatically display images from strangers. Because of their design, she can't check messages that she wants without possibly seeing a stranger's dick. That, and there's no easy way for her to report them for that message.

Neil Fiore's "The Now Habit" deals with the emotional baggage and provides techniques (including "time boxing" which is championed by The Pomodoro Technique) for dealing with the emotional baggage.

If people are concerned about the gem installation (and not the promotion itself), I can suggest that you promote harrow differently. Maybe put it as part of some command's output. Like "Cap by codebreaker (thanks to funding by Harrow.io)" or similar.
I read quite a bit of that and I'm not sure where it mentioned their revenue source.

I did see some mention of funding, and of very small fees (relative to operating a company) for having your integration on their platform.
Honestly Google's rep for discontinuing support for stuff is why I'm not interested in such a connected device. Will it continue getting updates after Google drops it in 0-5 years? Who knows. Will the open-source community be able to put OpenWRT on it or something to give it life after it can no longer receive firmware updates? Not sure.

I do know that my current Ubiquiti and Apple network infrastructure devices will still work if I plug them in in 10 years. I can't say the same for this. $200 seems reasonable for what it does, but less so if it's knocked down to dumb router mode if Google pulls the plug some day.
I wonder how much of this is mitigated by good lane discipline?

My SO actually got pulled over the other day (or at least that's what the cop used as an excuse) for driving in a passing lane when not passing anything. I said I was glad because it's a terrible habit - every lane ending up going the same speed as the slowest driver
You just described exactly what I described in various other posts. How you came to the conclusion that I "don't seem to understand" can only possibly be due to some sort of zealot blindness that makes you a defender.

Best case -- terrible abstraction.
Worst case -- you're rewriting much of your code for each platform, working on a 3rd party incomplete abstraction that is always behind and full of unnecessary layered surprises.

What a win!

And for the next bizarre Xamarin sponsor that decides to wallow in and throw up this -- I worked on a large scale solution with Xamarin. We threw it out and just went with separate projects for each platform, sharing code with C++. Works wonders. Way better than Xamarin.

Khanacademy has some good resources, seemingly, including teaching Big-O notation. Also, if you are familiar with a programming language in particular, Rosetta Code can give you an example of the algorithm in that language.

But in my experience (which should be taken with a grain of salt, as a person who never took cs and never took calculus), understanding algorithms doesn't take a lot of math, just a bit of persistance in understanding how they work, and a dash of common sense. The hardest math is that behind calculating big-O for time and space, which can again be approximated for most simple algorithms with a bit of common sense. This (http://stackoverflow.com/questions/487258/plain-english-expl...) stackoverflow is probably the best explanation I've seen.
