Initially I was going to say you're overstating the danger, but first I went to Wikipedia: https://en.wikipedia.org/wiki/Criticality_accident#Incidents

Note the first one, where the system went critical simply because the scientist leaned too closely to it and neutrons bounced off his body. Only his alertness to some red indicator lamps and resulting quick action saved him, vs. the 1st to die of this who in theory could have taken corrective action before getting a fatal dose.

Then again past a certain point almost all of these resulted from violating rules. Note from one of his autobiographies how Feynman was prepped to really get the attention of the people running stuff at Oak Ridge I think it was if he realized they'd created a system that might result in a criticality accident.

Ah, and there's this big difference: I grew up a couple of decades earlier than us, and still have my mother's Civil Defense Block Mother sign from the late '60s. Back then the madness of MAD hadn't completely taken over and if you were interested, the government was happy to train about how to survive a nuclear war, which really isn't difficult at all if you're outside the immediate effects range.

So to me radiation is to be respected, but it's an understood and mitigateble danger. I'd rather work in this field than in a university synthetic chemistry lab (one possible direction I could have gone if $$$ hadn't prevented me from getting my undergraduate degree). Staying safe there requires tremendously more knowledge of a fantastically more complicated field, resisting too much pressure to work when you're tired, and trusting the others in the lab not to screw up too badly.
And THAT is a primary reason utility companies are fighting grid-connected consumer solar right now. If you are grid attached you are part of the cost of maintaining the grid that is normally offset by your revenue to the utility. If you are just using it as a glorified battery backup by feeding in excess during the day and pulling during the night and you are a net zero to then company then your per-customer revenue is much much lower. If only a small percentage of customers do this then you can level it out. If that percentage starts to grow then something has to give. Either you lower your maintenance budget, lower your operating costs, or lower your net profits. No one directly involved wants any of those to actually happen. This is obviously greatly simplified (e.g. The extra cost of handling customer generated power), but you get the idea.

Hahaha. I love how you end this with another one I had to look up.
Keep in mind that $30K for 85KWh is pre-gigafactory and is also for a vehicle. There are many more safety factors involved in making a battery that is going to moving around at 70mph. Much of the cost of the vehicle based batteries, may be able to be skipped, if you are not as concerned with mobile safety and weight.

The "grid" doesn't yet exist in certain plots of land. One may want to build a house in the woods, but not pay the costs to get electric/water/sewage run to the property from whatever main road is closest.
The Tesla Model 3 car, due in a few years with a fully online gigafactory, is supposed to retail for $35k I think. This certainly means that Elon is expecting a price drop in the (car) batteries by quite a significant amount - perhaps even down to a price competitive with Lead-acid for the (home) batteries discussed here.

Ask HN: Working through burnout?
I know, I know, the solution to burnout is to slow down and take some time off.

What do you do when you're exhausted, your brain is fuzzy, and you just plain have to meet a hard deadline in a few days? You have obligations to your team and your company and yourself that just can't put off.

It's all well and good to say you'll take a week off once the deadline is met, but how do you keep your brain operative and your mind focused enough to read and write code for those intervening 3 days when you can barely read a sentence of plain English text without having to go back over it 3 times to extract any meaning?
There are several factors but the biggest one was India, I never understood why software quality from India was so poor. Honestly, it made no logical sense, here is a population that has a group of individuals that are for whatever reasons fairly strong in STEM. It seemed inconsistent, until one day I met a developer named Karthick, Karthick could code and was a passionate developer, he was everything that India software quality was not. So I asked Karthick about my observations and why software coming back from India was so poor. What I found out amazed me What I thought was a complex problem, was actually a problem of incentives. See Karthick told me that in India, a man is measured by how many people he manages. It is a throw back to the cast systems and it is a source of pride. The fastest way to management, in India, is STEM and specifically computer programming. So what you get is a bunch of would be MBA's, getting engineering degrees, that they do not want, to take a job that they do not want, to get a job they are not educated for and are not qualified for. So it creates a fail up environment.

This was the first wave of problems and honestly after the failures of BoA and several other US companies who lost billions trying to save a buck in that market, US companies are hesitant to enter that market again whole hog. They will pick up a developer or two to augment a team, but not many people are sending whole projects over anymore. Everyone has a horror story and it's enough to make most would be bargain shoppers think twice about trying to save a dollar, by trading it for risk.

The second issue is one of tribal knowledge as I call it. People conduct their lives in very different ways from Central Asia to the US. What we take for granted as common knowledge over here may be a uncommon or not even done in your culture and vice versa. When we document systems, we take for granted "common" knowledge and it does not get documented. For example I worked on a system one time for a large hotel reservation engine that had work done in India. 2/3 of the development staff had never personally booked a hotel room online. It ended up costing more to have BA's and Architects document the system, than it would have to have thrown the BA's and Architects in a room with a bunch of developers. In the end what did we do, well we sent our CTO, our BA's and our Architects to India to sit in a room for 2 months at a time until the project was a success. Basically enough from the VP's to declare victory and get the hell out.

So what does it all boil down to, cultural mismatch. As US business homogeny (I don't mean that in an arrogant sense, I mean it in a corporate culture way) and the Internets global village takes it's hold on the globe, that mismatch becomes less of an issue, but someones is going to have to take the risk to prove it out, and unfortunately the generation that smashed on the rocks in India is now in the decision making seats and not many of them have an appetite to try a do over. Especially startups where project failures or delays can kill a promising idea.
>you can't even live 'off the grid' in a grid tied system

I can't find any references for your stated claim about Connecticut, however it seems deeply illogical given that a generator (which surely aren't banned), solar panels, wind, etc, all have the potential of feeding energy back to the grid in an outage. Which is why there are regulations and home inspections and all of that, to ensure that the appropriate safeties and switches are in place. Simply banning one of many possible mechanisms of generating power would be very short sighted.

Many regions that offer feed-in time-of-day tariffs are rightly trying to figure out how to accommodate battery systems, where some users are trying to game the system by charging a big battery array during low cost hours, and then "selling" it back to the grid during peak hours (at inflated, subsidized prices).

EDIT: As a reply to msandford, given that I can't reply lower -- the reason they have this limit is that the tariff price paid to home solar/wind generators is way above the bulk, "wholesale" price of power. It was created as an incentive to encourage green energy. So when you feed back their own power to them, it does them no favor given that now they're paying 2x+ what they would pay on the normal power market for power, and simply undermines the entire incentive program.
Today I went to pick up two 100AH lead-crystal batteries for a long-run UPS (we now have regular load-shedding here in South Africa). If I believe all what I have read about them online, they are amazing, compared to lead-acid. Crazy heavy though (33kg each).
The same issue exists with grid connected solar panels. My solar panels are designed to stop working whenever there is a power outage. This is a legally mandated requirement here and is very annoying when it happens on a beautiful sunny day.

A solar panel installer told me that if I add a battery backup to my installation, then at least it'll still charge the batteries during a power outage.
It's really nice to see that happening, but every time I raised the subject with the Gnome team to see how we could run VLC in it, it's a no-go.

Indeed, for a complete media player, I need:

- access to files not directly opened by the user (playlists, MKV, DCP, MXF),

- access (and unique probably) to raw devices read-only (DVD, AudioCD, Blu-Rays, webcams-v4l2, SDI, DVB),

- direct access to raw audio output,

- access to X11 for YUV output, or at least a direct OpenGL context,

- access to network.

For access to files and network, there seemed to be a solution with a manifest to get $home access; for audio, a solution might come with kdbus and pulseaudio; but for the others, they refuse blankly, saying that my "use case is irrelevant and dangerous".

I hope this will evolve (maybe it already has), but so far, it's a bit hard to make a complete media player, tbh.
If the battery has sufficient excess capacity, you can split it into multiple banks of smaller batteries, and cycle which ones you charge and which ones you use. Add a small computer and you can use whatever logic gives you optimal charging/discharge patterns to optimise for lifetime.
If you are going to count hydrogen emission as a problem for a lead-acid battery then you should be honest and point out that lithium batteries of all varieties have a habit of failing in spectacularly combustible ways.

Sales Leadership
I'd love to have a self-contained electrical system for my house. I'd preferentially wire my home with a DC grid alongside the AC, but there's no standard. Do I run 120v, 240v, 5v, 12v? Which interface do I use? Barrel connectors, USB, cigarette lighter? If we have a large-scale movement to household DC, we'd have these things hammered out without me rewiring every appliance.

If these obstacles were overcome, almost everything in my house could run on DC. Most stuff either converts to DC internally, or doesn't care.

Possibly, but most of the Saturniid moths aren't aerial acrobats to begin with. None of them can fly with enough precision to really evade predators. One of the best behavioural defenses for flying insects (found so far) seems to be the Mantis' ability to take an immediate dive toward the ground upon detection of a bat.

edit: I should add that there actually are other well adapted behavioural defenses, such as this:

I find it interesting that your graph leaves out any mention of innovation or invention.

It also ignores corporate cultures.

Backend engineering for a web startup is very different to backend engineering for a Wall St HFT house. I wouldn't expect someone who worked in one to be expert in the other.

Even within the web startup world, fullstack with MEAN is very different to fullstack with PHP/Apache/MySQL - not just technically, but culturally.

So I think what you have is one of those toy models that management love so much.

I'd like to see some hard big-sample-size evidence that it really does improve hiring outcomes in practice.

We don't do any ranking per se we just present how you want to spend your time. So it does not factor it in. It is up to you to decide what level of seniority the type of position you would consider going for.

It might be a bit misleading that we use Github for sign up right now, this is mainly just to ensure only developers are signing up - as the service only exists for them currently. We do not use Github for any number crunching.
ukigumo, your experience is the reason why Gordon and I started Workshape.io - all the information out there is historical - what you have done in the past - and nothing at all on what you want to do in the immediate future.

Glad you like the service - keep an eye on us, there's a lot more to come
To further the analogy.. as soon as the fruit on the low hanging branches becomes bad enough to justify the additional effort of climbing the tree for the better fruit, people will do it.

Your argument makes it sound like you're saying no hard problems are being worked on currently, which is simply not true.
Most developers have good knowledge of English, Lets use IELTS for this, I guess scores are in range of 5-9 and arithmetic mean is somewhere at 6.0
No, the costs are better expressed in terms of price divided by total KWh stored and subsequently recovered over the lifetime of the battery.

So even if they can get the 'installed' price down to < 30% of what it is today (some corners can be cut for stationary applications) then there is still another barrier to be crossed.

All in all this is extremely exciting because manufacturing batteries at this scale will surely lead to economies unseen before but Lead-Acid has an 80 year head-start and is very hard to beat when weight and density are not a major factor.

After all the one reason why we have Lithium-ion is because of weight and power density.

I didn't say wealth wouldn't have been higher if colonization didn't occur, though I'm definitely unconvinced of that. I merely said that growth did occur everywhere.

We don't know this. The relevant counterfactual is not a perfect free market, but whatever the assorted kings of India would have imposed. I don't know enough about the history to comment on their likely economic policies.

Passing the Cloudera Developer Certification Exam
Yeah she has hit a very simple scheme to create her videos: pick some selection that has an arbitrary bias of her choice. Claim on video that "all of x" has said bias. (Another way to describe it would be "anecdotal evidence").

So in a video she would show only gendered Lego, omitting all the non-gendered Lego. Or she shows only video games with scantily clad women, omitting the context (might be portrayed as despicable to mistreat a woman in the video game, but taken out of context you may only see that a women is mistreated in the game), and omitting the zillions of video games that have nothing to do with women or gender at all. That way she "proves" that Lego is sexist and video games are sexist, and I don't know what else (haven't watched all her drivel).

People apparently believe anything that is presented on film.

I upvoted you to get you out of the grey because I didn't feel like your comment was too inflammatory and did bring up specific issues which are relevant in a big picture view to this change. That said, the CEO comment was a bit unproductive.

One thing I would like you to consider is that Firefox has to maintain a certain marketshare in order to continue to serve their mission. Which includes fighting for web standards and other things outside directly working on the browser/phone os. Unfortunately, that causes them to serve the larger market than what you or I might enjoy. I'm definitely not a big fan of the dummification trend in UX right now(which most of your complaints seem to stem from), but I'm sure it's just that, a trend, and we'll see some of the more ridiculous parts of that trend move back toward the middle soon enough. Design trends are like the weather, if you don't like it now, just wait a bit and it will be sure to change.

So, hopefully you can cut Mozilla a little slack as they have a many headed dragon to feed and that set of compromises will leave everyone a bit hungry, but on the whole I feel more comfortable depending on Mozilla than the alternatives of Apple and Google.
But presumably cost will be lower when the new factory comes on line right? Otherwise why built it?
Such regulations provide several types of protection to the public commons.

Another group of people who are protected are firefighters. In a typical residential installation the power meter also serves as the service disconnect. Response protocols include pulling the meter before many other life saving and property preserving operations. Live equipment and conductors operating from a second source downstream of the meter are a serious hazard to fire fighting personnel.

Solar panels are a particular hazard because the sun doesn't have a disconnect, many firefighting operations involve working on the roof, and fire burns upward. A collapsed roof may bring a tangle of live electrical parts down into the building and create a hazard that persists long after the fire has been suppressed.

In addition, miscellaneous loads applied to a grid can bring it down. In the Northeast US, much of the infrastructure is old and therefore less robustly engineered than elsewhere.
> because if you have batteries which cause a back flow during a power outage to the power station, an electrical worker could get shocked

What is the difference between Battery backup and a wind turbine/solar? Somehow you are allowed to have solar and pump back to the grid, but not battery, geee wonder why that is.
What does that 'm' mean in the graph legend anyway?
I think the random walk is incorporating the "hidden" knowledge which clusters the nodes in the graph together. As they use inference to create the links between the nodes, that will (I believe) incorporate the knowledge forming a local neighbourhood of data which when traversed randomly will expose that knowledge.

Moving forward from the sparse to dense conversion (which is pretty clever) I think it would be interesting to look at learning properties of vertices or clusters from random walks on surrounding clusters. This would enable someone to capture information which might not be directly available (silly example: activity of a hidden facebook group, based on the activities/profiles of its members).
Namecoin is around for years, and it's true key-value blockchain database, not DHT with values hashes stored in chain within financial transactions(why?).

Like it! We are definitely looking to roll the service out to other verticals. Designers will most likely be next considering the complimentary nature of what you guys do! Thanks for the feedback.
>and are therefore lower on the epistemological totem pole.

Again, that is a philosophical position (logical positivism, basically) that would have to be justified by philosophical argument. It's actually a position that's very difficult to justify, as we found out in the first half of the 20th century.

>"The claim that physics plays that special role within scientology is itself a scientological claim. If you want to justify it you'll have to study Dianetics and get audited by Tom Cruise!"

Surely if you wanted to show that physics played a special role within scientology, then you would indeed have to study scientology. I feel like you didn't even bother to read through that example after you'd constructed it.

In any case, your weird example does nothing to demonstrate any circularity in my original claim. The point is simply that if you take a philosophical position -- as you have on the epistemological role of physics -- then you have to justify it. I don't know of any way of justifying philosophical positions without making philosophical arguments. If you think that you have one, then let's see it.

> no less an eminence than John Wheeler is on video saying, "Philosophy is too important to be left to the philosophers."

Who should be doing philosophy is a separate question. Wheeler, as you note, agrees that philosophy is very important.
