> In the US at least, a huge fraction of costs for residential solar are in customer acquisition. Something like 20%-30% of the cost of a residential install goes to paying for lists of potential customers and marketing to them!

Page 22 of the report[1] estimates sales and marketing/customer acquisition for residential solar to be 12% of the price, and says Vivint and Sunrun report it as 17% and 22%, so I think your numbers are a bit high. I also doubt that cost will actually fall- if anything it might rise, since advertising pays for itself. As costs drop it becomes more important to advertise the low costs!

Always gotta be careful applying 101 knowledge to a real world problem.

Also, this is an unfortunate misinterpretation of even econ 101. Econ 101 says that there is not a fixed demand for most goods. Demand (and supply) have elasticity, which is a measure of their responsiveness to price changes. A rational producer with perfect information does not "clear the market" if that means "supply enough to meet all demand for the good." (If that's not what it means, I really don't know what it does mean.) They supply just to the point where marginal cost of production is equal to the price the next consumer is willing to pay.

And, subsidies are not definitionally distortionary. Sometimes they can be used to correct uncaptured positive externalities.

ag = agriculture ... took me an embarrassingly long time to figure out it wasn't a technical term for something.
Security through obscurity is definitely not the solution, but I'll tell you that I've been running SSH on a non-WKS port since the mid '90s as a standard practice, and the number of attackers attempting to connect there seems to have been 0, even during the "lets try all sorts of common logins" crazy days.

Let's face it, the sort of person who moves SSH to a different port probably is also the sort to disable password logins. So the effectiveness of searching for their SSH daemon is probably pretty low.
IMO there are some extremely questionable design decisions in 11. Some of these are just ugly (like the super bold date on the calendar icon) or wasteful of space (like the headers), but others hide useful info or decrease discoverability (like requiring force touch for normal flows).

I’ve only been using it for half a day but right now the details feel sloppy and the bigger picture UX feels poorly thought out.

My interpretation of "meta-consciousness" as described by the article:

It is simply a brief period of intent, focused replay/study of the experience that just occurred, while it is very fresh in the mind/short-term memory. One is closely reviewing what happened, looking at the experience from different angles, replaying it, etc. This could all happen in the span of a second or less.

It is a matter of focus and proximity. It isn't a special layer of consciousness. It may seem qualitatively different, as the mental model of the experience is so deep & rich in the moments immediately during and after, if one is focusing closely. But I don't see the argument for this becoming some sort of "meta-consciousness".

In short, the concepts of "consciousness" and "being conscious of [something]" are related, but they aren't the exact same thing.
This is great news.

However, I wish the mac release was available as independent binaries without having to come along with Xcode.
How do you define indiscriminate killing? Carpet bombing and terrorism are at one extreme, WWII style bombing of military targets is a bit less indiscriminate, drone strikes are much less indiscriminate. Lincoln and JFK type assassinations are perhaps at the other extreme.

How do you draw the line at what's OK and not OK? As the GP suggests, it seems to be drawn at whatever level of technology the most advanced group has.

Personally, I think terrorism is one of the most moral ways of fighting. By definition, it creates a high level of fear with a small number of casualties. That's far better than, say, trench warfare with a high level of casualties but isolated from the majority of the population.
yea, but any specific plan that is put forward will go through an absolutely endless relentless well-practiced vilification process and many people will end up believing that the bill is intended to the do opposite of whatever it actually does, largely only to get people to listen to radio ads.
I lost the thread in the first two paragraphs. Can anyone explain to me why it's so obvious infants are conscious? THis seems to be taken as a given for the rest of the article. Couldn't they be in a state similar to sleepwalking which seems not conscious to me? Perhaps consciousness flashes on as you have your first few "flashbulb memories".
Reading this would actually tremendously help software engineers improve their concurrent/parallel software design skills as well. I never had a particular desire to do hardware (my degree is CS) but some of the best C/C++ programmers who were able to squeeze out every last ounce of performance truly understood not just software languages but also computer architecture and I might even go as far as saying understood physics to a large extent very well. The LMAX software architecture is a product of this kind of hardware+software understanding. Awesome article.
More paywalled crap. Don't you have a better link?
>If attackers have physical access to your machine, you should consider it compromised.

This bit of "wisdom" dates back to the very, very old days when security wrt computers was primarily a consideration for servers in physically secure locations. It is utterly obsolete, and every more so with each passing year. HSMs, CPU-level trusted modules, etc. have long since been a thing, as for that matter has even basic software measures like FDE. All exist in part or in whole to help with certain kinds of physical access. It is not in fact straight forward, reliable or for most attackers even possible to pull bits directly off a well designed physically secure chip with an STM or whatever.

I don't think looking back the actual weaknesses in MD5/SHA were related to ARX, but I'm not equipped to judge whether ARX might introduce TEMPEST related issues. It is not a fundamentally invalid consideration however. Side-channel attacks are one of the most classic and fiendishly difficult issues in cryptography and EM emissions are a known domain problem that can't always be solved merely via use of shielding. It's better even then to have it considered right down the primitive level. Layers and all that.

This article, like most discussions on "consciousness" I encounter reads like little more than word games to me.

We could similarly write articles about all the qualities and properties of phlogiston, and we'd have learned just as much.

What thing are we actually trying to explain here? What is the extensive meaning of the word "consciousness"? How can I emperically determine if some object/animal/thing possesses consciousness?

At this point it mostly just seems like we define ourselves to have this "conscious" property and then circularly use that as a distinguishing characteristic of humans.

How is "consciousness" not just a modern word for "soul", minus the afterlife stuff?
> If I remember correctly, clos had a strange naming connection that included the type in the symbol name

CLOS is built around multiple dispatch, so there isn't any type to go in the method name if you wanted; methods don't belong to a class, they just specialise generic functions onto any number of their arguments. What lispm described goes quite a ways beyond apropos, though.
The Command Line Tools include the Swift compiler without needing Xcode installed. Open up a terminal and type “swift” to enter the REPL or “swiftc” to compile a Swift File. SPM is included too.

When I got solar several years ago I watched as the various installers wasted a ton of time selling to me. It was clear that all the steps between when I was interested and when I gave the go ahead to start the install were extremely expensive in the big picture and in the long term the winners of residential installation would be those that will be able to drive that cost down and or spread that cost out to as many customers as possible.

They visited my house when I was just looking for a quote. The quotes were these large custom contracts with all the information which we would iterate a few times on.

I can imaging these days just going to a website, finding my roof, selection my option and getting a quote in real time. Maybe they would even let different installers all bid for the job, who knows. The website would have detailed information and information if I want it. Only if I did an initial downpayment would someone come out to confirm it could be installed. Someone like this could be able to drive the install cost down.

Or maybe "groupon deals" where if you and 4 other neighbors on your block all buy solar it is 15% cheaper or something. That would be one way to shift the marketing and sales to the consumer and not the installer.

Consciousness does not have to mean being "mentally" (intellectually) aware of what's going on. It's about experiencing stuff, and having a _sensation_
Worse yet is that the cost of these benefits creates an incentive for companies to prefer younger, unmarried, and childless employees over others. Until the ACA with the new preexisting conditions rules, it also meant that if you had a chronic condition of some kind, you were essentially stuck at the job you were at when you were diagnosed - if you switched jobs, your employer may not cover your preexisting condition, which could bankrupt you pretty quickly.
I thought Williamsburg was more expensive than most places in Manhattan now? You can find a ton of cheaper places in Manhattan (still expensive) if you are willing to go farther north. But then you have to deal with a longer subway trip. It's odd that commuting to midtown from Stamford, Connecticut is about the same from Inwood, Manhattan. If you don't mind an hour commute, and you work in midtown, metro north is really good and Stamford and the areas around are really nice and much cheaper. You can buy an actual house.
I wonder if there's a way to prevent this, I plan on talking w/ the head of security after reading this!
I think if the healthcare and education cost situation gets much worse, there's going to be a big drain of people who have the means to move to more civilized societies. Or maybe thats just a personal bias because that's what I keep edging closer to in contemplation. Tech salaries are better in the US than say Europe, but if that all taken out by healthcare, while adding all sorts of bankruptcy risk and poor standards of care then there's little point gambling.
> Is "consciousness" in the sense of the article just a synonym for "anything the brain processes"?

And is able to describe that thing, even if just to itself.

Have you ever experienced in a dream, being able to do some wondrous thing - write music, feel a wall from a distance, whatever. In the dream you feel that ability. But when you wake up, while you remember dreaming about it, you can not actually make yourself re-experience it. (For example: Describe the song you wrote.)

That's what the author claims is the difference between conscious and not conscious. (If I understood him correctly.)

If you have conscious thought, you can cause your mind to experience any sensation you have already had. A non-conscious being can not do that, they can only experience what they experience right this moment.
Thanks. I couldn't have summarized better.

Could it, though?

Remember, if you’re not in a swing state, your Presidential vote is literallly— not figuratively, literally— worthless. Same goes for your Congressional vote if you’re in one of the increasingly-common gerrymandered districts. And even if that’s not he case, the odds of your vote making a tangible policy difference are remote at best.

Sounds to me like Millenials are making an entirely rational calculation on their votes’ value.

If a software developer job is done locally -- in an expensive city like SF -- then the employer must pay at least a living wage for the region.

If the job can be performed remotely, then suddenly workers must compete with the global stock of candidates. And there are many locations around the globe that are much cheaper than low-cost areas in the US.
Maybe most of those roles can be lumped under devops. They probably don't have enough data to for ml/ai

Aside: I used to run a small ISP, a 200-300 dedicated+virtual machines. We set up our router to alert us if outbound SSH connections from a host went above a certain threshold, which was a super reliable way of detecting if a host was compromised. I think we had a near 100% success rate, because once a host is compromised they use it to start trying to compromise other hosts.

But, we also had every customer on a VLAN, limited to only being able to send traffic from their IPs, and also blocking incoming and outgoing bogon traffic.

Years ago I attended a presentation by Evi Nemeth (RIP) related to CAIDA and one thing they found in auditing "backbone" traffic was that some huge percentage of it was bogon traffic (I don't recall the exact number, but lets say 10% +/- 6%). Nobody wanted to filter that traffic because the pipes were less expensive than the routers to handle filtering packets at high pps rates.

Ah yes, 30% was too high. But 19% is what's reported by other analysts, such as GreenTechMedia [1].

Germany was once (ten years ago) the top PV panel producer. All it's MFGs, including SolarWorld[1] have gone under because of dumping and flooding the market with cheap PVs. This subverts R&D in panel technology both in Germany and in the US. In addition, some German PVs were hacked[2] and had their IP end up in the hands of CN MFGs, again, that subverts German (and any other MFG) R&D efforts in PV tech. So we may end up with retardation in PV R&D which is not a good outcome.

My best at guess is that the universe itself is conscious, and we'll eventually let go of the idea of individual consciousnesses. An ant hive sees a larger field more clearly than I do, maybe at a slower refresh rate but not by much.

Are individual ants conscious? Somewhat. Are we conscious when we're receiving reality through memes beyond our comprehension? Somewhat.

Are our rods and cones conscious? Our brain stem? The cells that make us vomit? The bacterial colonies in our sinuses?

I just think the answer to all of these questions when all is said and done will be yes. And we'll be sad how much life we killed because we didn't think it was conscious enough.

And maybe if we're lucky when we die we get to watch our consciousness grow to include all things. Maybe that's why we have circuits in our brain that seem to respond that way to mushrooms.

Maybe there's a genetic advantage to harboring the illusion that you are a separate consciousness, but it's just there to make you want to struggle to hold up your tiny corner of a collective consciousness.
> But our consciousness goes beyond simple self-awareness: having a theory of mind is a step beyond (and is realizing that others have a theory of mind a step beyond that?)

That [and this] whole space [of considerations, here] appears to be fraught with circularities like this:

Step 1. Draw a distinction between consciousness and meta-consciousness.

Step 2. "From what vantage point, and with what 'machinery' do we make a distinction?"

Step 3. Go back to Step 1.

> .. that our ability to think about the issue is constrained by our language.

I think I agree, otherwise I'm tempted to think that we would have already arrived, trivially, at some clearer kind of agreement about it.

The result, though, is not actual privacy protection. It's more that you choose to surrender your privacy to someone, in exchange for protection from other nasties.

It's almost like some kind of weird digital feudalism. You're free to come and go, and if you want, you can live in the wild and take your chances. But if you want the safety of the walls and armed defenders, that comes with a lot of strings attached. And if you ever want to move out of those walls, you leave your plot and your house, with everything valuable on them, behind.
