> solar panel cost accounts for ~20% of the overall installed cost in the U.S.[2]. So reducing panel prices by this incremental cost doesn't impact the overall cost as much as you'd think.

So where does the other 80% of the cost come from? Maybe we should be figuring out how to cut that instead.
Yep, sorry, SolarCity is mostly residential and commercial, so the cost breakdown is based on their sector.

The sad truth is some people have completely wrecked their insulin sensitivity b/c of poor diet. I'm not saying you are one or not, just that diet is so critical to a healthy life and our "approved" western diet is a recipe for disaster for most people.

My wife is a GP and she deals with obesity and T2D all the time. She says 3 things for T2D.

1. Lose weight
2. Reduce your carbs, go low carb as soon as possible.
3. Exercise, preferably with weights and walking/swimming.

She personally has never had a patient that actually did the above and wasn't "cured" from T2D. However, she has had folks who think losing 5 pounds or that low carb means not drinking the 5th coke of the day and don't understand why it doesn't work in 2 weeks. She has found herself to be an educator most of all. People just generally have zero clue on how all these systems work and she has to tell folks things like "yes, rice is in fact a carb. So is an apple and those waffles. Yup, the biscuit as well. Oh, you're drinking fruit juice for breakfast thinking you are being good? That's 45g of sugar right there. That low fat yogurt is in fact awful for you as a T2D".

I don't like to recommend nutrition advise over the internet, but if you haven't looked into ketogenic diet for T2D management, I would give it a look.
There's a nice pretty chart on the DOE's soft costs website.

http://energy.gov/eere/sunshot/reducing-non-hardware-costs

It's from 2010, so stuff has shifted since then, but ~50% soft costs, 15% installation labor, 15% non-module hardware, and 20% module. The DOE's really been focused on soft costs (customer acquisition, overhead, engineering, financing, etc.). We recently got a big grant to drive down the cost of getting a customer's bill/usage history for the initial quote, which can impact the overall cost by 5-10%.
As someone with a passing interest in solar although it's not at all clear to me how the economics would work out, I've found taking a look at SolarCity pretty frustrating. I get that every installation is different but any attempt to probe below the marketing buzz requires a phone number which sets me up to expect high-pressure sales tactics.

Indeed, my experience is that there's a lot of aggressive solar selling going on in advance of tailing off subsidies.

Agreed. The committee specifically awarded Prusiner (solely) the prize for the discovery of prions, because the committee for medical prizes (which turns out to be a bunch of structural biologists) was 100% convinced he was right, and they specifically told him that they were awarding him the prize to give him money to continue his research, because they knew his funding had been denied. (Memories of Madness, Prusiner).
Agree totally on the struggle being worth it. I'm not really complaining (at this moment, anyway, hah.

It is amazing how fragile it makes everything seem. I think a lot of those tools are safe, but yeah seemingly at any moment something could be abandoned or there could be some other drastic change in the chain.

Example: I can't even remember the specifies of this, but somewhere along the line I was having a hard time working with some npm module and while searching for answers I discovered multiple sources saying the module was "blacklisted". This eventually led me to an easy working replacement, but I still have no idea what the "blacklisting" means - it was still available on npmjs.com.

Also, building my Gulpfile.js was very interesting (and time consuming!). Seemingly so many different ways to approach it and I'm honestly not even quite clear on how I got it to work right so hopefully that doesn't break on me.

The only part of all this I expect to act on at my actual work, for now, is the IDE. I think I could really benefit from getting myself up and running on PHPStorm instead of Notepad++/FileZilla.

Was J2EE obviously awful at the time? I'm honestly not sure.

I had a summer job working on EJBs at a company that had built everything on CORBA. It was basically a research project; they knew they had to switch to EJB, because it was going to be the standard (ha), and they wanted to know how. This was in the EJB 1.x era, so somewhere between 1998 and 2001 - i don't remember exactly when!

I remember thinking that it was all rather complicated, especially around persistence. And i remember being appalled that beans didn't actually implement their interfaces. We came up with some rather complicated pattern to work around that - i think there was a master interface where all the methods threw RemoteException, then the bean interface trivially extended that, and there was a local interface that extended it but overrode all the methods to not throw RemoteException, then the bean implemented that. And i spent most of my time there wrestling with the fact that the performance characteristics of local and remote calls are very different, and how that impacted design; we ended up with DTOs mirroring every entity bean to save network round-trips.

But the thing is, there was nothing else around at the time that did anything similar. Remote object invocation, with declarative transactions, and container-managed object lifecycles, including pulling objects out of a database on demand. That seemed like saucer tech! So it seemed, glaring design flaws aside, fair enough that it was complicated. Hey, i might have to write an XML document, but at least it wasn't ten thousand lines of C++.

No, my logic would not extend to people with HIV/AIDS.

Why? Because the majority of people with Type II Diabetes (not all) could cure themselves just by eating less! Instead they put a burden on our health care system so they can maintain their habit.

A person living with HIV/AIDS doesn't have the ability to cure himself with a no-cost option. There's a huge difference there.

If anyone's wondering, SC's costs are above market average virtually everywhere, and they do not differentiate costs based on size (which is an immediate red flag for anyone concerned about costs, because it means they're averaging out fixed costs of small projects on larger projects instead of giving individual customers an individual price that's based on the individual costs + profit.) They're not a breakthrough solar company, there's very little technically that they actually do that's better than anyone else. They're a breakthrough business company in the solar industry by creating a scaleable organisation that cleverly securitises decentralised utilities, basically, that's different from Tesla or SpaceX where there's actual breakthrough engineering going on. It's done very well, it's hugely important and I'm glad they're a player in the space, but in terms of actual solar tech there's nothing novel going on here and they're usually not the best deal you can find (although it really depends on a lot of factors. Long-term non-bankruptcy is a big deal in a relatively young industry with many companies going bankrupt while dealing with products with a 20-year lifetime, and SC probably has some of the best odds of being around that long. That alone can be worth a premium to some people, at least in the solar lease business). Finally can we stop calling it Elon Musk's SolarCity, I like the guy as much as anyone and obviously he's a part of SC, but everyone knows that Lyndon Rive spends 100x as much of his time on this than Elon Musk and is the actual CEO running the place. The name Elon Musk isn't like Donald Trump, you don't need to headline it every time there's an association that's relatively minor, that's just clickbait, at least I don't think journalists should do that. He's on the board, he's not running the thing and he helped start it almost a decade ago.

It's so concise that I use more words to re-post it every time Monty Hall comes up than are in the explanation itself.
>There's expected to be a solar panel shortage coming soon because the industry is growing so fast[1], so if you don't make your own panels, you can expect panel prices to go up. The fact that SolarCity can make its own modules, means it won't be affected by the shortage nearly as much as others.

Why not? Even if you make your own solar panels, you still face an opportunity cost if you use them yourself instead of selling them, and that opportunity cost is identical to the regular old cost everyone else has to pay. So while it would benefit you if you happen to be making them when the price spikes, it wouldn't make you immune to the shortage I wouldn't think.

I most certainly didn't say there are only two types of people in the world. My comment clearly focused on designing around the user. Your user is different than my user, etc. I simply supplied two common use cases.

It's also a matter of designing around net positivity. If 70% of my users respond positively to a design then I've done pretty well. 30% in most cases is a small number. That doesn't mean alienating and ignoring that 30%, but it also doesn't mean throwing out the approval of the 70%. It's a compromise. (I didn't think I needed to be so explicit in my first comment).

Larger products, let's say Facebook, even 1% is a million users. So of course they can't ignore them.

> I wanted to know why I couldn’t work out how much food (carbohydrate) I was about to eat, measure my blood glucose, and then calculate my insulin dose based on those and other factors.

Ouch. I suppose carb ratios weren't so big back then (admittedly, it wasn't for me either, being diagnosed in the late '90s). But I still measured myself so many times a day that the pharmacist thought I was scamming the PBS for test strips somehow (our subsidized medicines scheme here in .au). As a curious teenager I was able to develop a mental picture of what my BSL did when I ate certain foods after a few months of 10+ measurements per day. So, even if I didn't have an actual carb ratio figured out, I "knew" by trial and error how much insulin different foods needed.

Even so, I've fallen off the wagon a few times. I got so used to having specialists and doctors tell me what a great job I was doing on my own, I had an embarrassingly long period between specialists. To the extent that I stayed on humulin for quite a few years longer than I otherwise would have if I'd seen a specialist (newer insulins are way faster-acting and easier to live with).

This story has certainly prompted me to re-evaluate where I am now; complacency is a silent killer.
Yeah, not recommended at all. I was pretty desperate and willing to see just about anybody at the time. I had a friend who went to the ND for diet/allergy, and I figured it was worth a shot.

She took my blood and sent it to a lab for allergy testing. That part was fine. She also prescribed me some ridiculous homeopathy stuff, and overall it was too much pseudoscience to stomach.
"Problem 3. One is a boy born on Tuesday. What's the probability both are boys?" - this is not a problem at all. The fact that one boy is born on Tuesday is completely irrelevant as the sex of the child does not depend on day of the week. That information is given only to mess with readers mind. So, if you ignore that Tuesday part then you can reduce Problem 3 to Problem 2.

I thought he selected it at random.

That was always the confusing unstated assumption for me, that makes me think the problem is only confusing because of how the wording usually de-emphasizes that distinction.

If he chooses a door, you can benefit from the secret information he reveals sometimes by doing so.

If the door was chosen at random, he is not adding any information, so you can't act on it?

> Knowledgeable developers know how to deliver web fonts quickly and web fonts that looks good on your system.

1. most developers aren't good, or at least not paid well enough to do what they consider a good job.

2. you cannot deliver web-fonts taster than you can deliver a page without web-fonts. Web-fonts will always be driving latency. On average in a noticably annoying way more often than not.

Besides... Downloading a 1MB font to render some typical 4kb of text? What sort of madness drives this behaviour?

I can definitely see the potential for a web-fonts blocker extension, like I now have ad-blocker and in the past had a flash-blocker (which now no longer seems needed).
It's not just about who's better or worse off. It's about the basic principles of meeting one's obligations and of applying the law equally. Would you be equally flippant about a law allowing any other group to shed their obligations without consequences? Bankers, perhaps? Or members of any ethnic group other than your own? It wouldn't affect you directly, as you'd be neither the debtor nor the creditor. Those people would be better off without you being worse off . . . except that we're all worse off when the foundations of civil society are weakened.

The situation with corrupt lenders and pseudo-educational institutions leaving others with nothing but massive debt cries out for relief. However, that relief should extend to a ll those who have been victimized - not just those who have yet to pay. Laughing or sneering at those who paid already, because it was both legally required and financially prudent that they do so, is pretty abhorrent.
I have no idea. How do you mean?
The problem is that many that suffered from J2EE v1.0, didn't had the "pleasure" to have worked either with CORBA or DCOM.

So they criticise J2EE, but don't get it was actually a pleasure when compared to these technologies, specially when adding the C++ portability issues across OSes and compiler vendors.

I think GCP's long term strategy is still to move all devops work into Google. They've stated this with GAE for awhile, and this is a logical extension move as part of that strategy for app devs who like to "SSH into their machines".

Like a lot of "cloud services", this is indeed nothing you can't do on your own box, and I imagine tens of thousands of people have done it before and will do it again on AWS. Google has now done it in a way that generalizes for everyone. Aside from what it lists on the page (installing the GC SDK and setting up authentication), Google handles all of the opsy stuff you would need to do on your own.

Running a Linux server and installing / authenticating an SDK is not really that hard, of course, but it's one less thing to worry about when developing an app. That's almost always always a good thing.
That's the rate though. For little sessions here and there during your working hours and per-minute billing, I feel like it'll be unusual to do more than say 5 hours a week even if you often forget to exit before the "garbage collector" turns it off for you. That gets you into below $1/month territory pretty easily.
