I haven't seen many market studies but those that I saw were... not very predictive beyond rolling dice and generic drawing exponential curves.

I think we might have reached the point where push comes to shove and solar is making its breaktrough. You can't really predict when that will happen. The best we can do is "when problem X is solved" or "price point Y is reached" then it will go off and "once it does it will reach XX% market share in a short time." Afterwards it is easy to pinpoint the exact time where it went off. But beforehand. Hard. Probably impossible. Many technologies die without gaining wide adoption.

The question I'm asking is not how fast solar will reach some percentage but where will it level off? 20%, 50%, 80% of total electricity generation? Will it replace fossil fuel or will it add to that? The total primary energy market is huge compared to just electricity. Will solar replace much of the primary energy consumption, too?
Funny, I was just listening to a podcast where Andy Weir (author of The Martian) was interviewed about his new book, regarding a potential city on the moon.

To justify a book about that Weir had to think of an economic reason why there would be a city on the moon, because cities need economic rationales. He theorized that the price of space travel had been driven down enough that it could support a tourist economy, so the economics of a Moon city could be modeled on Caribbean tourist cities. Conveniently, 85% of the moon rocks are anorthite- which smelts into aluminum, oxygen, and silicon among other things. All of which would be very helpful for building a moon city.

Weir didn't have much to say about international treaties mentioned in this NYT article. But a key connection between the article and how he ask and answers the question is that they both seem to regard a budding space tourism industry as a foundational next step.

The 2 Types of Software Engineering Interviews and How to Prepare for Them
The tendency is to lock in the first abstraction line that you thought of..which rarely ages well with future experience.

My rule of thumb is that something needs to be a function if it is called 3x, doesn't if it is only called from one place, and if it happens 2x it is a judgement call whether to leave cross-referencing comments between the spots or to factor it out into a function. (If it is unlikely that I will need a third and the common code is difficult to extract, I will leave comments.)
Okay lets see what the article actually says...
"The moon, peppered with the impacts of asteroids over the eons, should also possess dollops of platinum and other precious metals. Helium-3, embedded in the lunar crust by the solar wind, could be fuel for future fusion power plants."

Unconfirmed dollops of precious metals (no mention of how to extract this) and fuel for a type of reactor that does not exist. All this at the most inaccessible place humans have ever been!
Sounds lucrative.

I would have some annual re-qualification system, like maybe video comparison. You record a video when you register and another each year speaking about a specific current event and the system could compare the two and make sure the current event is correct.

Needless to repeat, but we'd also need methods for handling exceptions. Nobody should be denied use of the system because they cannot figure out how to use it or don't have a computer or smart phone.

I've lived through the experience of using non-MS products since the early 2000s, and all of those things are related. It has been one of their core strategies and still is, though the techniques are shifting.
Not sure who would run it. Nobody really cares that much.
Nice find. Their goals are quite different from mine though. I want the ease of SQL + server even if it does make a bit more maintenance work.
tether seems like garbage to me, I wouldn't trade BTC for tether.
The SB6190 is a $95 product right now. Plus, it's just DOCSIS 3.0. You can get decent DOCSIS 3.0 modems for ~$50 if you don't need maximum speeds. If you've got under ~300mbps connection, you could replace it pretty cheaply. For example, a Motorola MB7220 is about $50 without any discounts. Even a 16x4 is about $70. These are Broadcom based modems.
I had a drinking habit very similar to yours, and greatly reduced my drinking with the help of marijuana. Marijuana has the distinct advantage of not destroying my body in the same way alcohol does, and I find that it doesn't reduce my inhibitions as much as alcohol does.

The idea is that the US leads in safety tech adoption (which I believe is just an empirical fact) but that safety tech is reaching diminishing returns (conjecture), so that as time goes by it's tech lead helps less and less at lowering deaths per accident (relative to other countries), while it's accident rate remains higher.

This is really not that important. My point is that there are a million ways to explain the data besides the one you are suggesting.

The market found a value for beanie babies too. You are mixing up what classical economists called exchange value and utility.
Kraken is the only exchange where you can actually exchange USDT for USD. However, at the time of posting, you can only redeem 320k Tether before the price of it will half. Only 320k out of 650M+ (and growing) has any real value. Where are the remaining 649780k USDT going to be redeemed for USD? (Hint: Not from Tether themselves, they clearly state in their own terms of service that they're not redeemable for USD).
Pretty much, yeah.

For a CLEC, interconnecting in any given LATA[1] is a complex and costly endeavour—I mean the actual interconnecting, not opting into an interconnection agreement (ICA) for one purpose or another. CLECs are not beholden to any universal service obligations or similar social policy objectives, and will only connect in higher-density metro-type markets in which there is profit in doing so. The business case has to be there, and that generally comes in the form of downstream VoIP service providers having customer demand in that area.

So, hyper-rural folks are deeply out of luck. We deal with this scenario all the time in my line of work: "hey, anyone know someone who can port a number in this $LOCAL_YOKEL territory out in $NEVER_HEARD_OF_IT?"

Even with Enterprise edition it is very difficult to disable all telemetry. The lowest official setting for telemetry is "security" which still sends data to Microsoft (see https://docs.microsoft.com/en-us/windows/configuration/confi...).

There are, however, a number of hacks that can trim that down even further. But being hacks they aren't guaranteed to always work--things frequently change.

Since writing the article mentioned a couple comments up I have tried completely ripping out all telemetry components from the install CD, which seems to be the most effective option. Tools such as Blackbird (http://www.getblackbird.net/) also are quite effective. Nonetheless, monitoring traffic still shows connections to Microsoft-controlled servers. There are so many ways Microsoft (and therefore possible governments) can gather--or at least infer--information about your system.

To completely protect yourself would require manually monitoring, selecting, and installing updates, manually updating certificate revocation lists, constantly watching for new settings (including firewall and hosts entries) that must be addressed, etc.

So no, it is not possible to completely disable all forms of Windows 10 telemetry without also committing to an unreasonable amount of work.

I’d be interested to see a timeplot of the timing of ICO’s against the price/trading volume of bitcoin. My feeling is that there’s a lot of wash trading / market manipulation of bitcoin going on by the perpetrators of ICO schemes, to provide themselves with a way to funnel money out of crypto into dollars. The Bitfinex / tether fraud only works of bitcoin keeps going up.
This story was submitted with the current title, but from the URL it is clear that sci-news change the title before. The previous title was better. I guess it was something like "Physicist confirm quantum tunneling in water" that is more specific and makes more sense.
> Basically, I find the "there's always unsafe code somewhere at the bottom and therefore it's the same as 100% unsafe" to be overly reductive.

I totally agree; it's not the same. However, I think there is disagreement about whether saying only "there's always unsafe code somewhere at the bottom" is better or worse than saying "it's 100% unsafe".

I tend to write some sketchy unsafe code, and the only thing I can say with a straight face is "please don't use this if you care about safety", i.e. treat it as if "it's 100% unsafe". I'm slightly weirded out that Rust has a keyword that amounts to "I understand UB really well; tell others to trust me on it transitively".

I'll be less weirded out when the UB story gets shaken out more, or if cargo gets an "audit-unsafe" option that shows you all unsafe blocks you transitively depend on (does that exist yet?). Still like Rust, but letting randoms write unsafe code is scary.

Yes, Facebook is the "bread and circus" of the modern world. Plus, it's a dream come true for intelligence agencies, as people build their own dossiers and then make them public (or keep them within Facebook, which is pretty much the same to the intelligence agencies).
Right, Tether is a scam. But my point is that Bitcoin can be sold directly for USD (not USDT) on some exchanges.
> and the examples section is usually last

A far better answer to this would have been a project to (1) improve man page examples, and then (2) create a small alternative man page client that displays only the examples (or puts them up top).

Having said that I do see the need for what tldr is doing, even though I would have preferred it added to existing tools. More often than not I only find man pages useful after I have needed to look up something. They're usually OK for wholistic understanding, but often too dense and assuming of far too much contextual knowledge to be useful in the heat of battle.

Only if they cash out. You need new investors to be able to cash out. The wise ones smell the crash and are the first ones out. Some make it out just before the crash when the party is still going but the fires are rising. The rest burns. There is no real value in bitcoin (unlike the stock exchange or fiat money where valuable people are trapped in contracts).

You, man, said it right!! I am just invested with about a thousand Euros in the crypto world, and I mainly did it for one reason: I don‘t want to be last in the game and get some hands on experience. But mainly, I just want to be able to tell my grandchildren one day about that crypto craze that occured in about 2017. Its crazy, irrational, completely new and that is why I love it for that moment in my life.
Mining the Moon to fuel fusion reactors with helium 3 is a cockamamie scheme for the foreseeable future. First, nobody has made a fusion reactor that produces net electricity even with the least demanding fuel (deuterium-tritium). He-3-deuterium fusion requires significantly higher temperatures. Second, if He-3 did become a valuable fuel, it can be manufactured here on Earth by irradiating lithium with neutrons, just like tritium; it's what tritium decays to. Finally, the lunar regolith concentrations of He-3 are at the parts per billion level.

The latest He-3 prices I can find are around $2000/liter (~$15,000 per gram). At 18.354 MeV per D-He3 fusion and 40% thermal-to-electrical efficiency (generously), one gram of He-3 yields

1/3 * 6.02 * 10^23 * 18.354 * 0.4 * 4.4505 * 10^-20 = 65565

kilowatt hours of electricity. To produce 1 kilowatt hour of electricity, the helium 3 cost alone would be 23 cents. For comparison, the average retail price, delivered for electricity in the US is below 11 cents per kWh. Even if you had a working fusion reactor all ready to turn He-3 to electricity, He-3 would need to be an order of magnitude cheaper to have a prayer of He-3 fusion competing economically against other electricity sources. And if He-3 is an order of magnitude cheaper that makes it correspondingly harder to turn a profit mining the Moon for it.

Helium 3 lunar mining is not an investment opportunity. It's the end product of motivated reasoning, where the motivation is "I want humans to be doing more things in space."
5 is do-able by an undergrad, though the first time you encounter the concept it can be difficult to grapple how you would implement it.
The net profit should already account for all costs including liability insurance.

Apart from that, if I couldn't afford the $70k holiday cost, then I'd probably have to get a temp job working up there for a bit - though the economics of migrating between aren't discussed.

This is quite standard in the functional programming world; Common LISP, Scala, and Haskell all use "vector" to refer to (usually growable) contiguous-memory arrays with efficient random access, as opposed to "lists" with efficient append and prepend but inefficient random access.

Chrome Devtools – Part 1 Manipulating the DOM
I believe people finally got the point that all their "social engagement" is pretty useless.
Thank you for mentioning Nim here. :)

To expand a bit, Nim features its own JS backend with a high proportion of the stdlib supporting it. You can access the DOM via the `dom` module[1] and build some pretty cool stuff[2][3]. It doesn't target WebAssembly (yet) however.

On the systems side, Nim compiles to C/C++/ObjC and manages memory via a soft real-time GC (or via a choice of other GCs including boehm).

One reason might be because this gives the US too much influence over the world (I know I am oversimplifying here). As long as everybody got along well, and most of the countries in the world were growing economically, the dollar served a common goal. But now we are increasingly heading towards a world where trade wars are common and policy makers are looking inwards rather than outwards. Perhaps all the armed conflicts that US has gotten into also lead to more ideological misalignment in the world.

So, in such a world, I wouldn’t find it so surprising that certain countries would like to wean themselves of the dollar. Of course, this it is more important for powerful geo-political actors like China and Russia, than Somalia (uses USD extensively), and as an example you can look at how China is planning on offering a yuan priced oil contract that is backed by gold.

Prior to attending a week-long ayahuasca retreat in Peru, a psychiatrist friend decided to use ketamine to induce a controlled state of dissociative identity in which one detached aspect of her psyche could observe the machinations of another. Curiously, after returning from Peru following a mentored DMT regimen she reported experiences similar to those reported by oceanghost. Buddhist mystic types contend that one's psychology is a function of 'atmanah' (some sort of co-minds) interacting with a individual's 'prajnatma' (one's self) [Dhammapada text]. Interesting. IF valid (BIG IF) then nobody would be what they seem.
I never bought into the pure functional programming hype. Most programs are made up of many functions and as the program gets more complex, the code paths keep getting longer... If you force everything to always be passed by value and returned by value (never by reference) it's clear that the costs of constantly cloning all these objects would quickly add up.

The problem with pure functional programming is that it prevents the developer from writing well optimized code.

State change side effects might be dangerous, but they're also a really good way to boost performance and sometimes they're totally worth it.

> They are different because network effects aren't inherently monopolized.

Natural monopolies arising from network effects aren't "inherently monopolized" any more than natural monopolies arising from high fixed costs. Two of the most powerful monopolies in the last few decades (Windows and x86) arose due to network effects.

> A non-natural monopoly can actually be eliminated and replaced with a competitive market that needs no further government intervention.

Both network effects and high fixed costs can cause an industry to tend towards natural monopoly. The government can split up Facebook, but network effects would cause one of the resulting companies to eventually dominate the others.

The cost of mining bitcoin is dependent on the value, not the other way around. This is because the rate of creation of bitcoin is essentially fixed. If the price rises, mining becomes more profitable, so more resources go into mining, but the difficulty also increases. So the same amount of bitcoins will be created, but the energy cost of mining a bitcoin will increase proportionally with the price.
It's not always advantageous to be efficient, and this is even more true in really important areas like food supply, because having the extra, underutilized capacity can save you in a pinch. When it comes to frivolous things like computers and phones and cars, it's much easier to favor efficiency,because the breakdowns can be really problematic, but still less immediately endangering.

Evolution is perhaps the best example of how being inefficient can be hugely beneficial in the long term.
