I thought Google Analytics had a decent privacy policy that would prevent Google from doing anything with GA data. But I remember some fuzzy wording like "your data" which could simply mean that Google considers GA data to be their data.

Has anyone done a good deep dive on what Google actually does with GA data?

That study is also badly outdated. Under section 5, Life Cycle Inventory Data, it says "The authors have assembled this LCI data set to the best of their knowledge and in their opinion it gives a reliable representation of the crystalline silicon module production technology in Western-Europe in the year 2005/2006 and Balance-of-System components of the year 2006."

I would love to see a life cycle assessment using wholly up-to-date numbers. I keep reading new studies on PV LCA, energy return on investment, and/or energy payback time. People who write these sorts of papers don't seem to keep up with what industry is actually doing. You can learn a lot from data sheets and trade publications. E.g. from published glass thickness and module size and efficiency, you can calculate the quantity of glass currently needed per watt-peak. It's significantly lower than any of these studies using decade+ outdated numbers.

I think part of the problem is one of incentives. Academics writing about LCA are often comparing some hoped-to-be-up-and-coming technology against the mainstream. Like thin film PV, organic PV, or dye sensitized cells pitted against crystalline silicon PV. In that case using old numbers for silicon PV helps the newer technology look like it offers exciting improvements.

Another problem is that reviewers apparently don't care very much about these temporal effects. They don't chase the citation chains to find the really outdated measurements cited in recently submitted manuscripts.

Another problem is that the solar industry has grown large and competitive. Cutting-edge numbers about energy consumption for silicon refinement are probably retained as a competitive advantage by the biggest producers, for example.

It's possible to set tighter upper bounds on resource intensity just from teardowns of recently manufactured modules. I suppose that teardown based analysis may itself be the sort of information you only get from specialty publications like the Photovoltaics International magazine, which is expensive and not indexed by DOI or part of ordinary academic libraries. (So it's not even in sci-hub.)

It's $599 a year if you want to be able to read back issues of Photovoltaics International from their archives:

I am interested enough in photovoltaic technology that I have bought a couple of $100+ specialty books from academic publishers, but $599 is a bit too steep even for me.
I recently took a few days apart to implement my own SAT solver. The idea is to describe the solution space of each clause by a dnf. Then intersect the solution spaces (dnf1 and dnf2).to_dnf() in a way such that the intermediate solution space representations are small. In the end it is solving ALLSAT, by converting cnf to dnf.

I'm happy that it works well for many small sized problems.

It's important to note that when people talk about drug abuse and its impacts, they are usually referring to heroin and opioids, amphetamines, cocaine and other alkaloids, benzodiazepines, and so on. While some of those drugs are hallucinogenics, none of them are considered psychedelics, which is what the current decriminalization conversation is about.

Magic mushrooms, LSD, and cannabis are in a different universe psychiatrically, addictively, and experientially. It's like comparing viagra to chemotherapy: yeah, a blood thinner carries extra risks for certain subpopulations, but chemotherapy has visibly destructive side effects on the entire population.

Very interesting idea, but not sure Twitter sentiment analysis tells us anything. Most Twitter users don't tweet, and most college-age people are not active Twitter users. Instagram would provide more comprehensive data.

Even then, you have to make a variety of (sometimes shaky) assumptions:

1. The data set is a representative sample

2. Sentiment of social media posts is a good proxy for happiness

3. Machine analysis is sentiment is reliable (i.e. doesn't fail when it encounters sarcasm, which is common on Twitter)

This is a nice analysis of what Ralph's is up to, but they aren't exactly exceptional. The entire purpose of any store's "loyalty program" is to collect as much data on their customers as possible.
> 500 ug of LSD, though, is a pretty hefty dose, and I'd be surprised if one's "fun" didn't eventually turn in to a seriously ego-shaking if not ego-destroying experience, which is difficult to face on a regular basis.. that's if it's real LSD, of course.

He could just have a better brain than the rest of us. He could be at peace with himself and the world. I have heard stories of monks in Asia who, having spent the past 50 yrs meditating everyday, took LSD doses from Westerners and didn't react. Of course no one has ever proven these stories.

Timothy Leary gets a lot of flack, but the fact is that he was greatly responsible for spreading the word about benefits of psychedelics and getting people interested in them. There's a good chance that some of the people at the FDA and DEA now who are approving the current studies in to the effects of psychedelics (studies which were forbidden for decades before them) might have had their own psychedelic experiences due to the popularization of psychedelics by Timothy Leary and company.

Also, we have to remember that there were all sorts of negative sensationalistic news coverage in that day, like the suicide of Art Linkletter's daughter, which he blamed on LSD, and then there was Charles Manson, who used LSD in truly evil ways. Then there was Ken Kesey and his Acid Tests, which, if anything, were far more irresponsible than anything Leary ever did, and yet Kesey hardly ever gets the blame for that, and all the blame is heaped upon Leary instead.

Something else to consider is that LSD use was strongly tied to the counter-culture and the anti-War movement, both of which were anathema to many in power in the US. I don't think that all of that association can be laid at Leary's feet. The fact is that young people at the time were interested in these substances and they probably would have flocked to them even had Leary never existed. The time was ripe for it.
Yes! I did this many years ago, when it was all one course. I only got around to doing the SML part but it really improved how I approached learning new programming languages and frameworks (not just FP languages). I'm very thankful for what I learned, it has really help my a huge amount in my career! I'd highly recommend it to anyone who feels overwhelmed with all the 'new stuff' coming out. Much of it can be learned much easier if you look a little deeper and can ask the right questions.

If you are in CA for a tech job, a good plan is to get established and experienced and then eventually move somewhere else that's nice and cheap and work remotely. You'll continue to earn lots, be able to buy a house pretty quickly and, depending on what your criteria are, generally have a high quality of life. I am speaking from experience here.

Obviously I'm not talking about people who move to the Bay area to start a business, etc.
MIDI is not "just an event/messaging protocol", although it could be used like that. MIDI describes an application-level schema for "channels" which allow for the dynamic control of "notes" including pitch, poly after-touch, etc. It also provides for channel-level control parameters, various special application-level events. Global clock transport, bulk data transfer, etc. It's true that you could implement all of these with OSC, (indeed there is a standard embedding of the short MIDI messages into OSC), but OSC is in general silent on application-level semantics. This makes OSC a much better choice if you want to implement some other semantic, but you still need an application level schema for commercial music devices, and that doesn't exist.
You might want to look at how the editor is built. The editor uses the Godot engine as an "engine" (as opposed to a framework).

So the UI and everything are written in C++.

Thanks for the confirmation.
I didn’t have to go any further than the login and signup screens to see that it doesn’t feel native.

- No transitions between screens, just jumps

- Tapping field brings up keyboard, then whole screen jumps up about 30 pixels instead of smoothly animating

- Scrolling while there’s a blinking cursor has cursor detach from field until you lift your finger

- Doesn’t respect dark mode

- Doesn’t respect dynamic type consistently (text size)

- Other weird little display artifacts

Not saying it’s terrible, but it’s a good example of why native is still the way to go if you can afford it. It’s just a better user experience.

Google. Chrome is the most popular browser, Gmail the most popular email, Android the most popular mobile OS and Google the most popular search portal.

But I think "real work" is a bad criticism. If the kind of work it can do is the problem with the iPad, then why is the iPhone so popular?

The real "problem" with the iPad is the size. Laptop have been getting smaller and thinner (gigantic 17" laptops used to be a thing). iPhones have been getting bigger (more iPad-like or at least iPad mini-like), but it's probably close to big enough.

It turns out Steve Jobs was wrong. The iPhone is not a too small version of an iPad, the iPad is an iPhone that's too big. That's not to say there's no room for it in the product lineup. It just happens to be more like the Mac Mini than the iMac.

For about 20 years, I have been observing the paper-book-to-tablet ratio when I'm on the bus. Of course, back when I started it was because I was wondering if tablets would do away with paper books. Now it's just out of habit, because in fact the smartphone turned out to be an unintentional ally of paper books. I see people with both paper books and smartphones, but people don't normally want to carry two screen devices with them, and they sure aren't giving up their phones. So the tablet/e-reader/whatever-you-call-it peaked 5-10 years ago.

Of course, this discussion is about work, not how one reads books, but I think something similar is happening. Tablets are too close to other devices (laptops, smartphones) which are not going away, and therefore they are appear to have hit a hard upper limit.

My 14-year old daughter used to use tablets; now she uses her chromebook, her smartphone, and her desktop, but never an iPad. Most impressively, she even uses a Wacom tablet, which she plugs into her desktop, because she liked it better than the iPad for drawing. I think she is not alone, and people her age will go into the workforce more accustomed to using phones and laptops to get things done.
We had a rare occurrence of snow in our small town. Some kids went outside to play and a neighbor called on them to the police. Lesson learned - just stay in the freaking house all day.
I'm pretty sure it doesn't.

That would be a quite tricky thing to do. You would probably need some very specific architecture in your application to allow for something like that.

It's not clear to me that this is a better architecture than just splitting your application into two or more processes, one of which is of such lasting value and high quality that it would never need replacing. Then still, you may be better off making your gateways/endpoints not need 100% uptime in order to maintain availability, or making your client applications not require total availability to behave well.
There is no point charging batteries with expensive nuclear energy when cheap renewable energy can be used. And the operator of a battery can shift when they are charged, making nuclear even less likely to be the cheapest source available at any time. So this doesn't save nuclear.

Heat is difficult to transport any great distance, and the reactors we have today produce only moderate grade heat, which isn't very valuable. And if PV becomes a bit cheaper, then the cost per joule of its power will become comparable to the cost per thermal joule of natural gas. In that situation, consumers will shift to resistive heat, and be able to bank that heat in large thermal stores. This will provide enormous cheap storage capacity for that solar energy.

EROI of renewables is just fine, some horribly flawed claims to the opposite notwithstanding. In particular, the EROI of PV was estimated to be about 8 in Europe -- but that assumes one puts the solar-powered PV factories IN EUROPE, rather than in a location with more sun. The real issue there is that energy-intensive industry will flee Europe in a solar-powered world.
If you can't afford high property taxes you're incentivized to allow building so market rate housing price goes down (or at least increases slowly).

With Prop 13 people have zero incentive to allow building because they benefit from extreme housing value increases with no downside. Prop 13 also means only new people are paying any of the real costs for the town since their property tax dwarfs the tax of old owners (one year of a new owner's property tax can be more than the entire cumulative thirty year payments of a neighbor).

I wish Prop 13 was changed so every year local town failed to build X houses (where X is some large value determine by how large the property tax spread is from new and old owners) property tax on those protected by Prop 13 would jump 10% capping out at the actual fair market valuation of the property.

This way if people don't want to build at least they're actually paying for it.

This will never happen though given the current incentives.

I think the key problem is that housing can be an investment or affordable, but it can't be both.

"so you've got a way to transmit money from a "sucker fund" to a "winner's fund" with plausible deniability"

I've been thinking about this actually for quite a while, on a small-time scale. Consider the following scenario:

1. You have a fair amount of money in a Roth IRA, and roughly the same amount of money in a taxable account.

2. The limit on contributions per year is like $6K, and even if you put money in a 401K and then convert whenever possible, that's limited to $19K/yr I think. How can you work around this?

3. Let's assume you're approved for options in your taxable account; and my understanding is that you can buy options in a Roth account - you just can't write them.

4. So, what if you create a synthetic long position by purchasing calls on a broad market fund in the Roth, and selling cash-secured puts on the same fund in the taxable account. And maybe buy some short term corporate debt fund in the Roth to make up for the missing dividends. Not sure if you could also earn some interest on the taxable side. If the stock market goes up in the long run, then you have most of your gains tax-free in the Roth, and minimize your taxable gains. If the stock market goes down for a while, you have most of your losses in the taxable account, and minimal losses in the Roth.

5. I think there are some practical problems, but Matt Levine could probably write about them much more engagingly than me, particularly after someone tries this and gets in trouble for it.

More availability -> lower prices. A lot of people hold because the income:expense ratio on their property is really great. If your rental home goes from $1000/yr in taxes to the $15k/yr that every new homeowner is paying, you'll see that cut into your rental income. You could try to raise rent by $1000+/month but that won't happen because salaries aren't gonna rise that fast. So, you'll sell.

Thus, as a homeowner, when you go to sell then you will get less... A lot of these homes will fund peoples retirement in other regions. I see a lot of people in older age (who don't want to deal with renting, don't want to pass the home down, or didn't save for retirement) selling their homes here and moving to somewhere cheaper. They get to live a nice life off the gains they made.
The more I think about it, the more I conclude they just cannot afford to support tower or modular designs for the enthusiast market. Not only would they "lose" money from costly upgrades. But it would also become apparent the lack of driver support Macs have; especially as it pertains to video cards.

Maybe the Mac Pro will change the support issue and they will eventually be able to enter this market. But I believe their biggest fear is being compared to Windows or Linux which both have tremendous hardware support.
This essay feels a little trite.

There's a place for expertise and a place to be a noob. You have to keep learning.

But I find this constant degradation of work and effort, something I see a lot in Silicon Valley, pretty tiresome. I feel like the culture is pushing us to be dilettantes in everything, to be more clever, and to "work smarter", rather than putting in the hours -- striving for Olympic-level athletic performance, pushing the state of the art forward in hard science, or bootstrapping an industry cluster from scratch -- any of these could be 10-20 year undertakings.

This is pg, in 2012: "If you're not at the leading edge of some rapidly changing field, you can get to one. For example, anyone reasonably smart can probably get to an edge of programming (e.g. building mobile apps) in a year." http://www.paulgraham.com/startupideas.html

So yes, I don't think we should be provincial, but there is value in doing the same thing every day, and getting really, really good at it. Some things aren't so easily "disrupted". If you don't put in the time, you can waste your entire life chasing the new and shiny in 2-year increments, and accomplish absolutely nothing of value.
for some reason, it's getting harder and harder to build shelter. Shelter is becoming increasingly expensive and increasingly less affordable. This is in stark contrast to the progress that humanity has made in many other industries.

I think it's about time we started asking why. Most people don't understand why. Why is it so hard to build shelter. Why is something we've done for hundreds of years so well, all the sudden become so hard and so innaccessible that only the most elite can afford it.

I don't understand the decision not to use CoreXY. I have a very very similar plotter that also cost me next to nothing using essentially the same BoM as this. It's directly descended from this one [0]. It can absolutely fly, I've spent some time tweaking it but I can reliably and accurately drive it at something like 20cm/s. That's largely a factor of the low inertia of the CoreXY design, which keeps both the main steppers stationary during operation.

Anyway, plotters are dope and to anyone thinking of building one of these, I highly recommend a CoreXY based design.

I think this is an expectation thing. We grew up in houses that our parents owned in their 40-50's, after building their careers and wealth. Yet we expect to buy them in our 20s. That doesn't align with where my parents were in their 20s.
There are places where people make less than $80/mo, but they still have dreams and awesome ideas, and to deny them the opportunity to start programming and share their work because they can't afford to pay up is apalling.
