Ken Rockwell is nothing like Sheldon brown. Rockwell gets paid by manufactures to review their gear, and it’s ALWAYS a favorable review for the $$$$$ items. There’s no ads cuz he’s paid to put that info there.(product placement at its finest, if you will) Sheldon brown was an old guy that loved bikes and was full of knowledge, and his site was full of more information than just gear reviews, and some people loved and relied on it so much they decided to keep the site up after his death.
They produce solar and non-solar tiles. The "non-solar" are tiles which match the aesthetic, but don't collect energy.
You could reshingle a roof for $3.50/sqft and it's not unheard of to get traditional solar installed at $1.50/W, ~$15,000 for a 10kw system.

$7000 + $15,000

Then you apply the federal credit after that.

This is for a grid-tie system, I don't think Tesla is pricing theirs with a powerwall here.

Edit: apparently they're pricing it with 2 powerwalls, still cheaper by a sizeable margin however.

I dont think they re worried much about that anymore , people always return, they ve established their position. OTOH, it would be nice for google to have some serious competition on the web, esp. considering that FB has a great NLP AI team.
I have a friend in America who has a fairly large PV set up on part of his property. Listening to the all the obstacles he's had to overcome and all the surprising limitations he's saddled with, I can't help but suspect that the power company in his area that he's selling the power to would rather that these sorts of installations simply not exist.

Coupling that with the fact that off-peak pricing isn't the norm in a lot of markets, I have to wonder if trying to implement smaller build outs is really worth the effort or expense... though I'll be the first to say that I've not researched it thoroughly.
The coming electric vehicle transformation
Those that you listed are certainly good, but expensive. I got a kindle because it was cheap, but also because I knew there was a good jailbreaking community. I had to update my jailbreak and switch from launchpad to kindlets, iirc, the other day; inconvenient, but doable. I certainly see why a consumer wouldn't want to do it, but I don't see what a consumer would want to do on an open linux platform, either.

All that aside, you can run debian on a kindle: https://wiki.mobileread.com/wiki/Debian_Installation_on_Kind...

You can also run most linux applicaitons, provided you can cross-compile them. This guy has a bunch: https://www.fabiszewski.net/kindle-terminal/
UK solar subsidies were particularly daft in this regard - because we're further north and have terrible weather, capacity factor is pretty awful compared to somewhere like California, plus solar is guaranteed to contribute a big fat zero to peak power demand (which is after sunset in winter). It basically just acted as a hand-out to wealthy home owners paid in part out of the power bills of the less well off. Somehow this didn't stop our nominally left-wing party attacking the government for ending it, though...
The comparison on Tesla's site still looks misleading.

"comparable price of a typical roof + solar panels"

Having premium concrete shingles isn't a "typical roof". They also use small greyed out text to say they are comparing it to concrete shingles, but use big black text for the higher price, and hide the fact that the Solar Roof is only cheaper because of tax breaks behind a "See More" button.
Yes, of course!

Essentially centroid tracking works like this:

1. Detect objects (e.g. using TensorFlow) in each video frame

2. Initialize an incrementing ID for each object at the first frame

3. Compute the centroid of each object 4. For each object:

4.1. Compute the Euclidean distance to every object centroid in the previous frame. The nearest object from the previous frame is the candidate assignment.

4.2.a) If the distance is less than a hand-set threshold, use the object from the previous frame's ID for the object in the current frame.

4.2.b) If the distance is above the threshold, assign a new ID

> The very first "hypervisor" was L4 in fact, with L4Linux.

The term "hypervisor" was coined by Popek and Goldberg in 1974. L4 didn't appear until the 90s.
Interesting observation:

> To reach cost parity with personal gasoline cars, which typically travel 12,000 to 15,000 miles/year, battery prices must decline to near $100/kWh from the present value of $180 to $200/kWh. Projections of the year of cost parity for electric vehicles with gasoline cars globally range from 2022 to 2026 (5, 6). At that point, economics could well take over as the primary impetus for electrification, and electric vehicles would then be on a path to transportation dominance.

Either of your interpretations of Monty picking a door at random lead to a conditional probability of 1/2 that your chosen door has the car given that he revealed a goat.

I'm not saying that goat-car-goat could never happen. I'm saying that when you're evaluating what to do after Monty Hall has revealed a goat, the one piece of information you know is that goat-car-goat didn't happen.

I guess you're analyzing from the point of view of someone who's trying to figure out their odds of winning with different strategies before playing.

I agree with you that most people don't get the problem wrong because of interpretation. I'd go even further and say that many people who think they understand it don't get it right because of the interpretation.

Most arguments I see for the correct answer don't use the assumption that Monty knows which door has the goat, and therefore work equally well under a model of Monty picking the door at random. They're just picking different ways to model the problem and assuming a uniform distribution. You get the answer right if you picked a model where the distribution is uniform under the assumptions in the problem.

The real issue seems to be much simpler. Probability is not intuitive. Most people don't have the tools to figure out problems like this reliably, and those that do tend not to apply their tools when they think they see a simple obvious answer.
Super interesting, thanks for the reply! :)
You should take a look at the IMO problems - they are generally very different from any sort of math problem you’ve ever seen before.

For instance: Determine all finite sets S of at least three points in the plane which satisfy the following condition:
for any two distinct points A and B in S, the perpendicular bisector of the line segment AB is an axis of symmetry for S.

This is a deeply abstract and complex problem.

A tip someone told me here in the UK is that if you are buying an inexpensive property try and get one that was built and owned by social housing operators - they actually have much higher construction standards and will have been maintained properly.
AFAIU it's quite common in supermarket/warehouse refrigerators and freezers. Apparently upfront cost is slightly higher, but the refrigerant is cheap and there's no risk the next iteration of the F gas legislation will make your investments a dead end. And of course the environment friendliness is important to businesses that are concerned about their image.
Just as a side note, that algorithm for suffix array construction has really bad worst cases (consider a string of all "a"s).

It won't matter for experimenting or most likely for using it on smallish realistic texts, but anything where you're taking user data for instance you'd want to step up to a slightly more clever algorithm (there's an O(n lg n) worst case one that's still very simple, called rank doubling I believe).

The content is flawless. One old dude put a site together that is now The Bible for anyone who does their own bicycle maintenance. It’s a cult classic, if you will. People that want information on that specific topic use it, and the rest of the world just glosses over it or doesnt understand it’s significance. It’s not about technology, or who’s using js scripts, or a monetization scheme. It’s just pure information put together in a way that it’s target community can readily ingest.
Syntax-only formalisms are faster than semantically-laden formalisms; a compiler's parser is usually faster than its backend. Metamath is going to always be faster than Coq, Lean, Isabelle, HOL, Agda, Idris, or indeed much weaker systems like Haskell.

There's no RSI in working with Metamath. What I mean is that the workflow is largely dependent on me knowing what I want to prove and roughly how I want to prove it, rather than Metamath chewing CPU.
Apparently the build quality issues (roofs shorting, catching on fire) were traditional panels, and not manufacturer by themselves.

If you had panels overlaid you could easily replace them - or even upgrade them as technology gets better.
You’re shadow-banned, BTW, but I think your question is valid, so I’ll vouch your comment so that I can reply.

Walking through soft sand is simply slow and tiring. That’s it; you can do normal things, it is just slower. But the Kindle is like walking through mud in that mud tries to pull your boots off, you get filthy, if you get in too deep, it’s hard to get out. I’ll walk through soft sand, but I avoid mud if I can, just like I avoid clicking on anything other than the Kindle’s page turn area if I can avoid it.
...and yet it is particularly common in the UK for the home solar to be installed by a commercial provider (who don't get that subsidy, just feed-in tariffs), that provide the panels in exchange for the feed-in tariff from your roof. You get mostly free electric and sometimes some portion of feed-in tariff, they own the panels.

If it was that pointless, this sort of deal could never add up, for either party.
Awesome! Thx for the link
I used to live in Palo Alto. There’s VTA (bus) and Caltrain. Stops are few and far between so getting to and from the stops are in and of itself a problem. Buses tend to arrive every 15 minutes (or longer) I believe? Pretty infrequent. And outside peak hours there’s usually like one Caltrain an hour, so missing one really sucks.

I had a colleague who had to travel frequently between Stanford and Berkeley (slightly unusual); it’s a sub-hour drive, but easily takes ~3 hours or more via public transit.

P.S. At least the Valley is fairly bike-friendly by U.S. standard.

We shouldn't stop because of an edge case, because they do save lives.

It's like saying we should stop chemo because of unwanted side effect, because they don't work in some situation, or make someone worse because of an unknown variable.

Because they can cause harm in some rare situation, doesn't mean they're not valuable in many cases.

Levallois-Perret is a commune bordering on central Paris, and a comparable size to a single arrondissement (subdivision within Paris proper). For example, the 11th arrondissement [1] is 50% larger and 100% denser than Levallois-Perret. But it doesn't count because it isn't it's own separate administrative area.

All this to say: the closer you look, the harder it is to rank places by population density. The comment point was that high population density can be reaching without high rises.

Why would your understanding of consciousness change whether we should judge intentions? Either way we have a person who is acting on a decision to murder.

Which is why originally, we didn't have what we have today. We had a modified republic which allowed democratic elections of some officials, but not of others. Keep in mind that senators were elected by states for a long time, a good thing if you as me, as they were intended to serve as a sort of moderate gerusia and be less accountable to the whims of the public. Electors for the presidency weren't directly elected either, in many places. Again, I think this helped us see a president more as a leader and less like a head-man.

Indeed, too much democracy can lead to disaster. We're seeing already that we end up with mob politics, populism, and candidates competing as to who can spend more of the other side's money, pass more laws they hate, etc. I hate it, and this is why the federal government was supposed to be elected mostly indirectly and given a small role to play.
This is intellectual arrogance on full display.
I have a Xen hypervisor at home, running on a (well-configured) NUC. VMs boot in about 15 seconds. I'm patient!

I'm not doing devops stuff; I no longer code, so I don't need a testing pipeline.

I looked into containers based on LXC, when it was first introduced. I decided to stay away - I don't want to get tied into Poettering's code. Yeah, I'm running systemd on some of the VMs, but you don't really have much choice nowadays. I still use Debian, but I'm bitter about their adoption of systemd - and my hypervisor machine runs SysV Init, because I know how that works.

I never mixed it with Docker. From what I've been reading, Docker is already old-hat (it's only about 3 years old; how did that happen?) Kubernetes seems to be the thing nowadays. I don't even know how to pronounce "Kubernetes".

What was wrong with LXC? Like, LXC comes with the OS. Nothing to install. Why do people love these 3rd-party container engines?

And "wrappers"? what purpose is served by container wrappers?

Serious questions, I'm not trolling. Promise. I'm just a bit out-of-date.

Ask HN: What bug(s) make “LPRINT 0.00001” output “0.0XYZ1”?
https://en.wikipedia.org/wiki/Timex_Sinclair_1000#Bugs states:

On the TS1000 and ZX81, the command:

LPRINT 0.00001

results in the Timex printer outputting 0.0XYZ1.

I find that a curious bug (my best guess is that the “XYZ1” part is uninitialized memory, but even if that’s true, why would 0.00001 be special?), so I tried to track it down. to my surprise, I found very little. The best I found is https://www.tablix.org/~avian/spectrum/rom/zx81.htm, but that’s incomplete, and of the “Improved” ROM, which, presumably, doesn’t have that bug.

So, does anybody know how that bug came to be?

If you insist that it is "advertising" that is the cause of this malaise, then you must agree that "advertising" is not compatible with modern free democtratic societies and needs to be made illegal.
