Can anyone tell how to measure the R1-R14 [0] values of a LED lamp? It seems like a sort of a Gretag-Macbeth [1] card is used. Can I use a photospectrometer [2]? I'd like to measure R9 [3] & R13 myself.

I wish it was easier to get your hands on refined isotopes. I believe it'd spawn quite a bit of interesting industrial research that's being held back right now. A lot of this waste is a nuisance, but I believe if it was easier to get access to it, we'd see someone start to solve the waste problem.

> (1) The kernel can predict which pages the user will "almost never touch."

You're in for quite a surprise, particularly on desktop. I have a number of
processes with some pages swapped out, and I see no impact on interacting
with the said processes. Firefox, gDesklets, a volume changer, and several
instances of rxvt are among them.

> (2) Mispredicting which pages will be "almost never touched" is of relatively low cost.

> I also disagree with (2). The consequences of getting these predictions wrong seem to be very bad.

Only in the case of repeated mispredictions, which only happens if you
really have low RAM and are on a good way to invoke OOM killer anyway. With
(1) being quite accurate (mainly because swapping out unused pages is not that
aggressive), (2) magically becomes true as well.

Yeah, that keeps happening to me as well. Playback continues, but my phone seems to just lose the connection. When I force it to reconnect, either playback jumps to whatever my phone decides to play, or the Chromecast and my phone will need to restart a new piece of media to sync up again.

When it does work, it's pretty cool with multi-room playback, but I've decided I don't really need that anyway.

I'm working on phasing out the Chromecasts now, because of limitations in which apps support casting, and the inability to block ads and properly cast local content (very format-dependent). The kitchen speakers and CCA have been replaced by a rather good Bluetooth speaker, which is also handy when I go to hang laundry. The CCv2 and second CCA in the bedroom/office is being replaced by a ultra-small form factor PC with a wireless keyboard. For the main stereo in the living room, there's always at least one other device turned on anyway, and all of them can play from Spotify or my file server, so the CCA goes unused.

On the flipside, I plugged my old CCv1 to the TV in my girlfriend's apartment, and that thing has been working absolutely flawlessly, so maybe I'm just unlucky.
It feels like solving traffic mortality by pasting a "drive carefully"-sticker inside the windshield

Wouldn't a better analogy here be to "solve traffic mortality" by considerably reducing your exposure to dangerous situations (as in, driving less)?

There's a demand for meat, hence an industry working to supply (and profit-off-of) it. Encouraging people to eat less meat is making a difference.
> Consumers are key to change

Consumers are given responsibility for too many things. When I buy something I have to check how it impacts the environment, animal welfare, fair trade, worker impact, company social responsibility, price, antibiotic usage, palm oil usage, health impacts, allergens, various toxins, suspected list of toxic substances, company reputation, etc.

When will it end? IMO this doesn't scale... This needs regulation, I'm fairly sure the EU is doing it's part, where is the US?
I thought of something similar a long time ago: A regular-sized dishwasher that is divided into two working independent halves, also auto-drying after washing.

You'd place your dirty plates into the left, turn it on when full, place the next plates into the right, then the clean plates would be on the left while you'd fill the right one with the dirty ones, and keep alternating. This way you don't have to put anything away, you'd take the plates as needed from the dishwasher.

The nice thing about this is that it'd work with current dishwasher sizes, and no messy weird electrified cupboards. It could be manufactured today because it doesn't require special engineering, it doesn't require weird kitchens, and it's not a solution looking for a problem like some gadgets in the article.
Spotify will show the devices eventually, but it does seem to be rather slow, unless you've been on the wifi for a little while before starting the app.

> You just put dirty dishes away in the "cupboard", and then they get washed once the machine detects that there are too many dirty ones

That would mean either you wash every time you put in a dirty dish (which would be wasteful) - or you accept that you always have some dirty dishes mixed between your clean ones, including the food remains, fluids, smell, etc that come with them. Sounds really unpleasant.

More practical problems:

- Dishes can be stored a lot more space-efficiently in a normal cupboard than in a dish washer. You'd need a lot more space if all your cupboards are dishwashers. Putting in dishes correctly is also more complex for a dishwasher than for a cupboard - so instead of saving the effort to empty the dishwasher, you've multiplied that effort to all of your cupboards.

- A cleaning run takes time. If cleaning runs start automatically, you'll have random parts of your kitchen inaccessible at random points of time.

- If you used a normal dishwasher you find out very quickly that drying is not perfect - if you leave clean dishes for too long in the airtight compartment, you might as well rinse them again. If the cupboard are meant to store the dishes permanently, that problem will get bigger.

I know, which is why I said 'font rendering' - but of course (for any practical purpose) that extends into drawing onto a context/canvas/whatever it's called in a specific ecosystem. Pango can draw to Cairo (modulus some very pedantic definitions of 'draw'), for example, but in some combinations of glyph rendering/layouting/drawing libraries you have to fiddle with getting one library to render as a path and then use generic path drawing routines to actually rasterize. I can't be bothered with that sort of minutiae, hence my question - how much (if at all) is this library integrated with other functionality to render, query the rendered form, and rasterize text.

I mean, say what you want about DirectWrite and the Direct2D environment - but at least it's very clear how things fit together and it works very well, even for niche use cases. In open source land, you spend days just puzzling together the pieces - let alone build them and getting them to actually do something useful from code. I've tried plenty over the last 15 years.

I elaborated on this in a different comment, but I think there could be dishwashers divided in two independent halves that worked as you say, without requiring double the space.

Indeed; bought first-gen LG webos, top of the line, TV. scratch record bad choice. Severally underpowered hw, like a really old tablet. Thus, it cannot update to later versions of WebOS and apps are constantly crashing (did I mention that the regular TV tuner is considered an app in webos?).

To work around this, I simply bought a chromecast as a target to stream youtube on.
This is the exact opposite of my experience.

My Netflix app is extremely reliable with Chromecast. I had a period of unreliability when I switched to a new phone (Galaxy S8) that applued to Netflix as well as all other chromecast apps, but after an OS update it appears to be much better.

An easy hack: buy 2 dishwashers. Load one with dirty dishes until full and then turn on. When it is clean, tada! - this is now your cupboard. Load dishes into your other dishwasher until full, now repeat this process.

It's different to copy/paste code from SO and to copy/paste code from an open-source project with a non-permissive license and remove/ignore the license.

The controls to prevent developers from doing this sort of stuff in a serious company should be to let them know they will face disciplinary action/lose their job if they pull it.

When you want it to end. You're putting those burdens on yourself.
To counter - I have had an excellent experience with my Chromecasts (I now own 3).

It does everything I need, and while not completely perfect it has been really very reliable and generally 'just works'. As a user experience for playing content on your TV, the 'android as a remote' approach is great.
Something odd going on indeed... Either the bitter oranges were later grafted with lemon plants, or the reason to plant near the lemon tree was in order to produce, by hybridation, other seeds that had mixed attributes, some of which would be very similar to lemons. The former makes more sense however.

You're right it is completely not scalable, and not only that, but incompatible with present-day market economics. One of the most important things we give up for the abstraction of market transactions with interchangeable goods is information outside the transaction.
I actually do learn new stuff. While on the current job, I've been doing:

- Code-hinting (semantic analysis) in an IDE
- Product management
- Low-level JIT codegen & optimisation (for ARM Neon & Intel SSE)
- Some datascience (technology/ product evaluation for a 8-digit aquisition)
- One of the early contributors to a web standard
- Distributed systems, bigdata (mostly graph-processing at quite big scale - Facebook-big)

and probably other stuff I can't remember right now. I worked in half dozen different programming languages. I'm pretty sure I've "stayed relevant" more than the average Joe, but you wouldn't know it from github.
That statistic of efficiency probably deals with averages and we should certainly not measure anything against American averages because American waste levels are absurd.
I agree. I also regularly say that it's the best value money I have ever spent.

The only unreliability I have is with certain apps that don't appear to have implemented the functionality that well. The "NFL Game Pass Europe" app for instance sometimes forgets that it's attached to the TV and you can no longer pause/stop (there are workarounds). Other apps like Netflix have been extremely solid.
Or you could use Ecover dishwasher products, which are a bit better.
> there's a whole range of current accounts, savings accounts, tax-exempt vehicles, pensions, stocks, trusts, and property to hold value over the long term.

Lolnope. For my generation in Germany certainly not. Current accounts and saving accounts deliver interest ratios hovering around 0%, some even with negative interest. Tax-exempt vehicles are only for the ultra-rich. Pensions are a laughing stock, I'm 26 now and don't expect to have anything resembling a pension when retiring with 80. Stocks/trusts? Either you really have considerable savings to start with (due to minimum order fees it's not really worth it to trade below 10k) or you got the stuff inherited at which point you're rich enough to not be affected by anything. Property? Unless you want to invest in the rural countryside that's so far off society that you'll be lucky when you have a 2x64k ISDN uplink you are not able to get property, especially not since the latest round of credit regulations which make it all but impossible for the ordinary person to get a mortgage.

Oh and that all has the prerequisite of actually having money to save. The boomer generation has royally screwed up the current young generation. We're struggling to pay rent and (in the US) hope we won't have a major injury sending us straight into bankruptcy, and that's it. Money to save is something for the elite.

> It baffles me how scared people are of inflation given how low it is at the moment in the West and has been for years.

Low inflation has only been made possible by advances in "how to feed people with cheap garbage". Rents, energy, transportation - everything has skyrocketed, but due to bad selection in the comparison basket inflation is "low". Screw that metric.

It follows that if crypto is the most efficient way of buying drugs online, that it's probably also the most efficient way of doing other illegal stuff online. Of that we're both in agreement.

Where we'd disagree is on bitcoin or any digital bearer assets being an efficiency for transactions that don't require censorship resistance. You'd better make sure you're sending that half a million in savings to buy your new house to the right address, because it's gone forever if you mess up a single character. Also, even if you did get the right address, you'd better hope you aren't being scammed (because in both scenarios, the traditional banking system and the government at large has your back).

This is the point where you say: but multisig / smart contracts! For a start, if the 'smart' part of the contract is a human oracle, why use a blockchain in the first place (if you're both willing to rely on a third party). Additionally, point me to a single transaction where the legal ownership of a house was transmitted through a block chain transaction (with no human oracle).

Let alone crypto being a terrible idea for smaller transactions. Last I saw bitcoin at ~$20 fees, Ethereum converts to a brick as soon as someone comes up with a popular contract, etc.

> I have seen many developers who fail to do that.

How do they happen to be developers then? Doesn't being unable to implement a FizzBuzz quickly imply they can't code anything that is more complex, by definition?

By the way although I do understand programming (OOP, FP, SQL) and can develop a considerably complex app from scratch in an IDE like Visual Studio with ReSharper or IntelliJ Idea that would expand code snippets, offer auto-completion and highlight errors on the fly I doubt I can code anything more complex than a "hello world" using just Notepad and expect it to compile and run without errors immediately - I use to make small typos and miss some syntactical elements all the time thanks to my ADHD (but modern IDEs solve this problem). Also, a person standing behind my shoulder watching me code and counting time would decrease my performance by an order of magnitude at best. Does this count as a failure from your point of view?

> Facebook and the like function as sort-of public space

The obvious solution then would be to make it public space and not a private one. Make social networks a public utility. Then it can be governed without all the contradictions between the interest of public and private profit.

> If we don't tax pubs specifically for drunk driving incidents

However there is a special tax on alcohol (although I am not sure if this applies to all alcohol in Germany, even beer, in my country it does).

> But my primary point is that we shouldn't just ignore the constitution just because it's more convenient at the moment

Yes but what if the society is already damaged beyond repair when we finally do find a good solution?
Yes, but many of those people will be moving from other neighborhoods in the same city; when they move they vacate an older, less attractive, lower rent dwelling.

The history of US housing is (with a few exceptions, notably the post WWII housing boom) a story of people building premium housing that, as it ages, becomes affordable housing. Thing how many big old houses end up converted into duplexes or townhouses.

But lately we've 1) used zoning to stop the conversion of premium housing into cheaper housing and 2) used zoning and planning permission to stop the construction of premium housing and then wondered why we don't have enough affordable housing. What a mystery!

> It is complicated, though.

It's a complex system with many different forces in play, yeah, but it's not that complicated. If you build more housing, the price of housing drops. Building expensive apartments in a neighbourhood doesn't magically create affordable apartments in the same neighbourhood, but it certainly doesn't hurt.

The exception would be if, somehow, building 100 units of housing somehow attracts more than 100 families into the city from outside the area, which...I dunno, it could happen, but is it? Has it ever? It sounds unlikely at first glance.

Well, considering that current Intel laptop chipsets support only 16g of RAM, this is pretty much a hard limit. Yes, you can switch to desktop hardware, but that is limited to usually heavier devices which run shorter on battery. So there are some very practical limits on increasing the RAM.
