My parents have a large solar installation on their roof that they own outright. They paid for it cash, but if they hadn't had that much available, then a HELOC would have sufficed and not produced any of this kind of drama at sale time.

Don't lease anything on your house; it's a huge hassle. Get a loan/HELOC for it if necessary and the numbers work out, but don't enter into a long leasing agreement that can cause transferral problems down the road.
The article started with something that would cost that much but (as the investigative reporter finds out) is seemingly the tip an iceberg of a fraudulent business.

Well, there was definitely a bigger overreaction from foreigners living here, in fact. Thus the term fly-jin, thrown around quite a bit in those days. Pervasive PTSD and depression amongst the many thousands still displaced today ( specially the elderly ) is very real. There was an excellent article somewhere from a couple of years ago that I can't quite find right now.
pre-orders? That gives them cash to build what (pre)buyers showed they really want? It doesn’t have to be Kickstarter, per se, could be an academic grant, or a pilot project with an enterprise customer. I have seen this work well - from idea to V1 product without selling any equity. It’s a very efficient filter.

traditional VC model is great for generating scale and creating barriers to entry/competition, but few businesses warrant that kind of scale and fewer use the capital to create real barriers.

Lending is for cash flow businesses - you can have zero hard collateral (eg PPE) but if you have historical steady cash flows, you can get loans, no problem (in my experience). The problem here is few startups focus on cash generation. They are enamored with growth at all cost, aspiring to the VC model when it isn’t appropriate.

The main argument against in this case seems to have been that it's a surprising clause in the terms (which would invalidate it), with the counter-argument being that it's well known that these price differences exist, and thus shouldn't be too surprising to a consumer that the airlines added rules against their "clever trick", because otherwise the pricing wouldn't make sense. Without a rule forbidding it, it's contractual freedom.

The case in front of the higher court was against airlines that cancelled tickets (and denied transportation) when a leg wasn't taken, and the court decided that this was too too unfair against customers that had legit reasons to not make use of the leg and offered the requirement to pay the difference as a compromise that still discourages passengers that plan this intentionally.

I disagree.

Toad for example is really slow, but a lot of that is the design of the software itself (e.g. autocompleting the same thing twice is still slow the second time, because they don't do basic cache or predictive lookups).
> - in small teams quotas are enforced pretty loosely. Everybody understands that in a team of five engineers all five can be good and smart

Not at a couple of the companies I have worked for. Small teams were still expected to have average ratings that were close to the company-wide average.
The growth rate of the payment is 2.9%. This is only very slightly higher than inflation, on average.

Also, assuming that the lower home value came true, the original purchaser of the solar installation did put his money where his mouth is, and paid a financial cost to his environmental interests, which is the moral thing to do, regardless of whether he was "tricked" by the negative cash flows showing up in later years (and in this case, when he was dead).

I guess my main point from my multiple posts is that there is no free lunch. If the fully amortized cost of solar is higher than grid power, someone will have to pay. Someone with buyer's remorse, who fully understood the cash flow implications at the time of purchase, can still feel like they were tricked. And maybe, the pessimistic projections of grid power costs made by sunrun should be taken with a grain of salt, and it should also be acknowledged that this deceptive practice is helping the planet.

Maybe a game theory perspective is valuable here- assuming cooperation is possible, people place an irrationally small cost to global warming, and discount future costs (in this case, of their power bill) to an irrationally large degree. The way to get people to cooperate is to trade one irrational impulse for another.
Solar panels are not electronics.

Solar panels usually are warrantied to at least 80% of nameplace capacity out to 25 years. And there are hard caps on 1) PV efficiency (Shockley–Queisser) 2) insolation that are non-negotiable physics. If that system is clean and reasonably maintained, it will be 80% as good as they day you bought it (and probably 80% as good as a brand new system) in a quarter of a century.
No, someone did not need to pay for them. That's not how the market works. If no one is willing to pay the listed price then the product goes unsold. Sunrun has no right to paying customers at any arbitrary price level, same as any other business.

Conv layers are strictly special cases of FC layers (with respect to expressive power).

> For any CONV layer there is an FC layer that implements the same forward function. The weight matrix would be a large matrix that is mostly zero except for at certain blocks (due to local connectivity) where the weights in many of the blocks are equal (due to parameter sharing).

(per http://cs231n.github.io/convolutional-networks/)

In general, if you can make assumptions about your problem and the form the solution takes, you can find a good solution with fewer parameters and fewer data, at the cost of suboptimal performance on problems that violate your assumptions. Conv layers are an example of this.
Solar panels don't depreciate in the same way as most silicon. 20 years later, panels will still be producing power just fine, albeit with some degradation.

Source: my house has 23 year old solar panels, my garage has 10 year old panels, they all still produce plenty of electricity.

There are plenty of reasons to avoid dealing with these companies, but this isn't one of them.

I was getting the "Mexico vacation" scam calls several times a day. It took me about 10-15 times wasting 20+ minutes of their time before they took me off. I get different ones now, though, and I usually get them when I don't have time to waste their time.

I once got the credit card interest rate scam (by "card services"), and the 3-level guy got so pissed at me for wasting his time he redirected his complaint line to my number. I would pick up to hear swear words and other things. I had to unplug my landline for an hour.

I contacted AT&T, because a lawyer I talked with said that was the right way to deal with this, and I was blown away how little shits they gave and how much BS they tried to get me to do. I canceled that landline soon after.

You're better off buying the system up front if possible

When I looked into it in my country, the payback time for a solar system was 10+ years, and estate agents were reportedly estimated they added nothing to the value of the house.

Buying is all very well if you're sure to stay in the same place for 10+ years - but if you move in that time, better hope you place a high value on feeling you've helped the environment.

Not that having a mandatory loan you try to get prospective buyers to pay for is a better decision, of course...
I know we change titles to avoid click-baitiness, but surely "What happened when I bought a house with solar panels" is not so sensational as to require truncating to "I bought a house with solar panels"?

They don't. They only care about the clicks.
Premium PV panels can be worth it if they look better. My parents paid a bit extra for black rather than blue solar panels (said panels also have higher output), and the house really does look a lot better for it. This can matter come sale time; curbside appearance is very important in real estate.

I don't see any outcome that doesn't involve Apple clamping down more on who can sideload apps.
It took the non-profit that I worked for weeks to get the correct DUNS numbers that Apple would accept.

As long as nobody is charging money or misleading people in deploying these apps, I don't see a problem.

I think the problem with Facebook is that they were simply using their certificate to bypass the app store, and letting apps be deployed outside of their organization.

Why can't Apple just have this exemption? It costs $300 and isn't trivial to get.

It's impossible to not have the translator on the way. Even if you reduce the translation to words and sentences, the are plenty of ways to translate a word or a sentence that while being gramatically correct, could alter the meaning, you would still need the translator to pick the right one and not change the message.

So, in your translation, you'll still have the main disadvantage of relying on the translator, while gaining nothing.

It has to do with solar panels to the extent that there's very little else that anyone would put on their house that uses a transferable contract. Solar panels are the most common instance in which anyone would run into this situation. I'm struggling to think of anything else, actually.

Bind up/down to history-search-backward/history-search-forward. In ~/.inputrc

# your terminal might send something else for the
# for the up/down keys; check with ^v<key>
# UP
"\e[A": history-search-backward
# DOWN
"\e[B": history-search-forward

(note that this affects anything that uses readline, not just bash)

The default (previous-history/next-history) only step through history one item at a time. The history-search- commands step through only the history entries that match the prefix you have already typed. (i.e. typing "cp<UP>" gets the last "cp ..." command; continuing to press <UP> steps through all of the "cp ..." commands in ${HISTFILE}). As your history file grows, this ends up kind of like smex[1] (ido-mode for M-x that prefers recently and most frequently used commands).

For maximum effect, you might want to also significantly increase the size of the saved history:

# no file size limit
HISTFILESIZE="-1"
# runtime limit of commands in history. default is 500!
HISTSIZE="1000000"
# ignoredups to make the searching more efficient
HISTCONTROL="ignorespace:ignoredups"
# (and make sure HISTFILE is set to something sane)

I think that's the scenario that happens the most often. My guess is that both parties here agreed to transact and then the TPO came out. Still it is not clear why the estate didn't just back out of the sale and then relist with the solar panel TPO disclosed. I guess the house only had one offer?

Solar panels in this type of deal are debt incurred by the home owner so the cost should be deducted from the sale price. In other words, do not buy a house with mortgaged solar panels.
