There's also CSP[0] which has taken off recently in the past 5 years (fastest growing[1] segment at ~4GW total vs ~177GW for PV) which is overshadowed by most compared to PV mind-share, but is better suited for projects that require more energy/load requirements.

I also can see CSP being more attractive to locales with existing grids and who can probably attract financing easier for a +100 MW plant to one institution vs 100k+ people having to be sold on such to install PV on their house/property. There's definitely a market for both and they will all chip away at fossil fuels rapidly coming from different sides of the market for energy.

The problem with CSP compared to PV is all the moving parts. You need something like molten salts, coupled with a conventional turbine and generator. PV can be purely solid state, a thing of beauty IMO compared to mechanical "contraptions".

That's less of a problem, and more of a feature, because those molten salts enable CSP to provide more power for up to 16 hours[0] sans sunlight which is important if you need dispatchability, which is not really comparable to PV's which cannot offer the same now, hence why CSP is not killed off by PV's and has continued to grow along with PV's.

You also have to consider that people who live in apartments or rent a house in developed markets are pretty much either locked out of the market for PV's or not incentivized to pay out of pocket (even considering the subsidies/financing that exist [looking at you Solar City]) for such systems. I'd say that share of the population is far larger than people with a mortgage/own a home and are interested in such systems.

This embodies the situation: "Does this mean CSP will eventually disappear, trampled by PV? Not necessarily. CSP has one major advantage over PV: dispatchability. Current CSP plants can store thermal energy for up to 16 hours, which means that their production profile can match the demand profile (just like a conventional power plant). PV is not dispatchable, as a feasible commercial energy storage system does not yet exist. Dispatchability will be increasingly important when and where renewable energies achieve high penetration rates, so two things can happen: CSP becomes a commercially viable solution before a commercial PV storage system is developed, carving its own market segment; or the PV industry quickly solves the storage issue and becomes the solar technology of choice."[0]

I agree with you, in theory.

Practically speaking there hasn't been a lot of large scale CSP done, and e.g. Ivanpah[1] has a lot of limitations and teething problems. It has no energy storage, and it needs to use natural gas for 4.5 hours each day during startup.

As for your assertion that CSP has continued to grow, the one data point I linked to claims "little appetite" from California utilities for power from plants like that.

One thing can probably both agree on is that CSP is a "go big or go home" technology. It's not suited for small scale deployments. Which makes it quite complementary to rooftop PV.

> "Practically speaking there hasn't been a lot of large scale CSP done…"

Maybe not in the United States, but it has taken off in Spain (looking at Wikipedia I cited earlier, which is probably better suited to take advantage of it in theory since installations are near population centers). I see far more interest oversees than in the United States… which is not surprising considering all the entrenched players that simply don't have the influence to the same degree in other places.

I can agree with this statement to some degree: "It's not suited for small scale deployments. Which makes it quite complementary to rooftop PV.", but seeing how it's serving a need that PV has not been able to provide to date despite it all, I'd hardly say its "go big or go home", there's far more abundant sodium and potassium available in the earth's crust vs lithium.

>As for [marching] protests - yeah I went to one of those once. It doesn't make much sense to merely volunteer to be kicking fodder for police horses.

I find it some what comical when people have a knee jerk reaction and advocate to others that the best™ way to protest is to do it in a way that that an institution/state is best prepared to deal with and puts the individual against forces that are completely asymmetrical in such domain…

Facebook banned my account last year, which was meh, but one of their engineering managers in NYC then used my email I signed up with to try and recruit me, and I just fell out laughing… they're a fucking joke and the aggressive sell on getting to work on react.js was equally humorous… yeah I'll stick to neural interfaces. I don't know how people put up with this shit in tech, but hey, different strokes for different folks and all that jazz.

What reason where you banned for, if you don't mind sharing.

C&D for linking to peoples facebook photos on a website me and a friend started where we mined and crowd sourced personality information. Kind of BS seeing how open graph makes basic information about every user "public", but yeah, didn't feel like fighting this in court nor had enough revenue to do so. We were able to keep the site up and running once we stopped linking to photos, but it changed engagement and pageviews dropped from 20k per day to 2k and we didn't feel like rethinking things at that moment.

If I were to do it again, I'd mine VK, Sina weibo, and Naver, generate some revenue, then fight fb in court so we can link to facebook photos or incorperate from russia or china, and subcontract the tech out to US company.

>So how is a quiet ego measured?

In our lab, we recognize is as deactivation in the PCC, some of our collaborators recognize it as deactivation in the DMN, measurable with both EEG/fMRI.

>All in all I don't buy it unless there's more to it.

I'd say it's preferable if more people don't feel like they have to "buy" into it… but as you know, there's a burgeoning industry surrounding such, but I'm mostly grateful that I get to be apart of working on the technology which I'd say will be way more useful outside of just meditation and contemplative practices…

As we can all see by this thread, the human biases/incentives that go into being a moderator of a forum can be quite suspect… and automated attempts that aren't transparent in totality from people which such biases (i.e. all of the weights things have on hn and the branching logic that determines who/what gets [dead], despite the likelihood of people gamifying them to some degree) will be equally suspect…

An alternative interpretation is that some people have previously engaged in nationalistic flame-baiting, and mods want to prevent that as much as possible.

Well now that we're all a bit off topic, it also seems like some people have lived in Russia for some time and form opinions about a country that some people have felt the need to respond with their opinion.

I can see why HN might not want to show such to public viewers to be protective of their image if people have never came across the brand before and spent enough time to get a feel for what goes on here…

I'd also love to see the corpus on how HN classifies things as "nationalistic flame-baiting", but I as of now, I suspect it's usually ad-hoc indirect self-referencing ("I saw this user said something like $__non_exact_quote_of_what_some_user_has_said_ [which mostly reflects my personal bias/interpretation that may or may not be consistent over time, that may or may not be shared by others, but to the degree of which, I cannot say because I have no stats to show you]") to other instances where a mod has stepped in and labeled something as such.

I think that would be a much powerful citation… but yeah, not my forum, not my rules, HN/YC and their agents/mods are free to be transparent (and to the degree of which is defined as being transparent) as they like.

>For most people, aiming for professional, middle-class jobs seems the most realistic goal to aim for. Ain't a bad lifestyle at all, if you can accept it's silly to try to win a game that's designed to make you lose.

Except that seems like one is still playing the same game that enables the status quo, like you state in your example, is where most people end up anyways… who then will still worry if their large mega corp will be the next to lay off the next 40k workers…


Tell that to very prominent VC's in NYC that have been blowing this horn for years in contradiction to your sentiments…[0].

I think public schools (and schools in general as an institution) face the same problem universities are facing: the obsolescence on such a mechanism to effectively and efficiently disseminate knowledge as more and more resources are allocated for signaling of such rather than acquiring/pursuit of it.

I don't follow. A shell is just a software interface and interpreter like any other. You learn it by reading its manuals, documentation and proceeding to experiment. Whether you acquire the information directly or indirectly via tutorials, examples and other third-party sources is of little relevance to the point. It's an activity divorced from the scope of public education.

I do agree schooling is starting to disintegrate.


I'm not disagreeing with your sentiments, I was just more or less stating that, there are monied interests in NYC like Fred Wilson, where if you go back through all his blog posts (or crawl the links in the sitemaps and enumerate all the instances of "kids/children" and "programming/code" in the same sentence, or within 1 or two words of each other you will see that it is greater than 0), who feel that it needs to be in the scope of public education.


Oh, that much is obvious. Code.org is probably the most egregious lobbying offender on that front.


Whenever a good thing™ comes along, there seems to be the tendency for some in a society to want to jam it down others throats (this is far from being the only "We need ____ in schools, NOW!" initiative), and the more ways the better.


I think it depends, will the teachers need a degree to teach kids?

I can see someone who dropped or didn't go to college, but worked professionally for at least 4-6 years in different technical roles would probably take the ~$50k as long as they can have flexibility create their own lesson plans and don't have to teach to some fizz buzz test on pen and paper (part of society's tendency to drive things to the LCD)… might be a breath of fresh air from their typical corporate environments, at least for a couple years.

Do I think something like this will happen, probably not.


"Many country and city governments in the United States choose to "opt out" of GAAP practices as they operate on a cash basis, as opposed to an accrual basis."[0]

If publicly traded companies are expected to report GAAP numbers and our governments aren't, it has to make one wonder… it certainly makes it harder to determine how to go about effective resource allocation in a society, especially when we're asking kids to make informed investment decisions about their futures…

That's the high quality NYT for you… I hope we see more high quality investigative journalism like this on HN!


I think the only good thing about these type of whitewash pieces on HN (of which I don't even bother to click on) are the comments here that do the work of the journalists… but NYT history is pretty suspect when it comes to things surrounding corporate and government reporting so that's not surprising.
