Geothermal power is based on a heat engine: a machine which produces usable energy (e.g. electricity) out of the transfer of heat from a high-temperature heat source to a low-temperature heat sink (a process which would happen naturally, given a transfer process).

A ground-source heat pump is a heat pump: a machine which consumes usable energy in order to move heat from a LOW-temperature heat source to a HIGH-temperature heat sink (a process which would not occur naturally without energy input due to the 2nd law of thermodynamics).

Diamond Age, Snowcrash, and Seveneves are much more accessible and (IMHO) better.
You nailed it. Bitcoin is not some kind of panacea that will make everyone rich. It's just money that cannot be fucked with by central bankers, governments, dictators or anyone else for that matter.

That's it.
I'm not sure what you mean, drug possession is still criminalized? Has been for years, and drug use still happens, it just creates conditions which increase crime and unsafe use.

Unless, do you mean that the laws aren't enforced enough, hence the drug use outside law enforcement? I would argue that increased enforcement still doesn't help the problem, and crime and drug harm increase. Not to mention the public costs of enforcing these laws and imprisoning people on small drug charges with mandatory minimum sentences.
Why do you think it’s hard for one microservice to generate links to another microservice? The alternative is that all the clients are tightly coupled to both of them.

I really believe that. Remember that the size of the housing market didn't protect it from manipulation in the early 2000s - having a huge pile of independent market participants doesn't mean they can't all be tricked into trading at the same inflated prices.
German universities tend to kick you out just as quickly as let you in. When the students are paying thousands in tuition you can't do that. You'll let them stay to get their tuition money even if you're wasting the time of that student.
Anathem is definitely my favorite novel of his, too.

Seveneves: just stop after act 2. Pretend the last couple hundred pages of the book don’t exist.

Fall: this is the first Stephenson book that I ended up skimming. I could not bring myself to care about the endless retelling of Paradise Lost. And yes, I’ve even read The Big U. It was better than Fall, imo.
My intro to his work was his essay: In the Beginning... Was the Command Line [1]. Back then I didn't read Snow Crash; a couple of years ago I did. Loved it! I haven't been able to get through Cryptonomicon. I did like Diamond Age, but as another commentor said it falls off at the end.

The gold is intended to back the cryptocurrency that the modern-era folks are trying to get off the ground. An unassailable gold backing for the currency, plus the data haven project, was supposed to prevent genocide by making fascism more difficult to implement. I think.
I find this argument overly theoretical and unsupported. Book selling isn't a natural monopoly. If Amazon dumped books and forced out everyone, can they really then use that monopoly status to raise prices? The market has a fairly low barrier to entry and any attempt to have high margin pricing would be met with new competition pretty quickly.
This has to be shared with the world.

Agreed. Anything that simplifies the build process and leads to less custom tooling is very welcome.
Very nice indeed. I bet it wasn’t the intention of the author, but the intro sounded a bit critical of Octopress and of how it fell behind, and so on.

Perhaps I woke up in the wrong mood, but I’d have praised the authors and community of the tool, it’s open-source, was built with generosity out of one’s own free time. That’s quite a capital!

So, we all know stuff gets abandoned, people do move on, perhaps they could handle handovers or sunsetting better, but let’s be first of all grateful.
It's not so simple, you need to look at the total number of people in each age group or you may fall victim of Simpson's paradox [1] (as both of those reports say):

> These data should be considered in the context of vaccination status of the population groups shown in the rest of this report. The vaccination status of cases, inpatients and deaths is not the most appropriate method to assess vaccine effectiveness and there is a high risk of misinterpretation. Vaccine effectiveness has been formally estimated from a number of different sources and is described earlier in this report.

In particular, the reduction of death rates among non vaccinated over time may be caused by natural selection, i.e. the weak died already while the remaining ones have unusually strong immune system (aka survivorship bias [2]).

There may be other unaccounted confounders, too, such as a change of behaviour over time where the degree of change is dependent on the age group and/or vaccination status. For example, an apparent reduction of effectiveness for younger people may be caused by them going back to work/study, thus increasing their probability of getting infected, while older folks staying in care homes as before.

Funnily enough, both Simpson's paradox and uncorrected confounders can result in observed correlations that are opposite to the real causality effect.

And to clarify, I'm not saying your VE numbers there are wrong, just warning readers about the dangers of statistics.

Multiple desktops/spaces, with my mainstay apps each assigned to one desktop, fullscreened with BetterSnapTool, and helper apps like notes, terminal, calendar & mail assigned to all desktops then just swap between apps/spaces either by pressing the dock icon, by four-finger swipe (very quick if switching between adjacent spaces), or four-finger swipe up to open app expose and switch between apps or spaces. I love this setup, and whenever I'm forced to use Windows, I'm incredibly frustrated by its comparably terrible window & desktop management
Demand is a group phenomenon; anyone who participates in the act of desiring a house drives up the prices. It’s not just the buyers, and certainly not just a particular age group of buyers.
Its purpose is to define a common standard for mutual exchange, but most importantly it is to bring everyone to the table. On the basis of such declarations talks can ensure. It is a process before being a commitment.
> They of course do give a damn about theoretical concepts such as "The Great Monetary Inflation"

It seems you tried to shift the subject mid-discussion and thus move the goalpost. The point being discussed was "proof of violence by the state", but somehow you've tried to change subject mid-discussion to inflation and how they argue that going long in BTC is a profitable investment.

In fact, the Winklevoss Capital article you quoted even praise the US dollar as "a reliable store of value" and even go as far as praising the Federal Reserve and it's "comparatively good management".

This doesn't sound like "fight the power" to me. In fact, it just reads as a marketing brochure selling an investment.
You have pledged that money, there is nothing inconvenient about it. You can place it in a seperate bank account of your own awaiting investment if it breaks your brain less.
> They can do whatever they want - increase block size, change mining algorithm, increase Bitcoin supply etc.

I won't deny that they do hold some power, but I don't think it is as complete as you claim. There is in effect counter-powers to the devs: miners and users.

Imagine a scenario where the guys who have commit access tot the repo decided to change the block size via a hard fork (much like what happened with bitcoin cash).

The next day, there would be a new github repo with the unforked original code, and there would be two Bitcoins sharing a common history up until the fork.

Some miners would switch to the new fork, some would stay on the original one.

Much like what happened with bcash, there would quickly be people selling the fork they don't believe in and buying the one they like.

Before long, the users (and the miners) would essentially do what amounts to a vote (some with mining power, others with buying and selling), and we would end up in a situation like the one we have today: BTC at $66000, BCASH at $600.

So, some power (like with the taproot upgrade, which ended up having actual consensus with miners and did not create a revolution with the users), not absolute power to decide what Bitcoin is and isn't.
Isn’t the issue equally that people (presumably poor people, since it’s poor neighborhoods) are selling their houses to rich buyers? It’s entirely possible to only sell to a poor person for a lower price.
Neo v2.3.16 released (animated lists)
Mental Ray is used by literally nobody anymore. It was discontinued in 2017. You can't even get a license for Mental Ray anymore.

Pixar didn't license any particular special GPU rendering tech from NVIDIA in 2015; they're just using OptiX and CUDA like everyone else. Pixar released initial GPU support in RenderMan this year, but currently XPU only supports a subset of the full RenderMan functionality. Before that, the only GPU ray tracing they were using internally was on an extremely limited basis for early lookdev workflows. Final lookdev and all of lighting continues to be CPU-only. I likely know more about this particular usage than you do because... I worked on the early internal GPU ray tracing for lookdev stuff at Pixar.

Autodesk Arnold has initial GPU support, but it was only added in the past few years. Most studio usage limits Arnold GPU usage to lookdev; most desktop workflows for iterating continue to be CPU because again... not enough memory on GPUs. SPI Arnold has no GPU support at all. Yes, there are two Arnolds out there.

After Effects is not really used for high-end 3D rendering? Why is it on your list? Did you just do a Google search for "GPU renderer" and throw what you found into a list without actually understanding what each thing is?

V-Ray has had extensive GPU support for many years now, and it probably leading the pack among usage in film/vfx/etc houses. However, most film/vfx/etc places use V-Ray CPU for both iterating on the desktop and for final frames, due to GPUs not having enough memory. V-Ray GPU has seen wide adoption in the archviz world though.

Gazebo is an OpenGL viewer, used in DCC viewports. It's not even remotely close to a final frame renderer. Manuka does not have GPU support whatsoever; the Manuka development team literally published an entire ACM TOG paper on this topic which I guess you haven't checked.

I'm not entirely sure how you put your list together; everything on here is either out of date, misunderstood, or just flat out wrong, and all in ways that are immediately apparent to those of us who actually work in this industry.
Yeah, many people seem to completely miss the game-theoretical feedback loops built into Bitcoin, the most obvious of which being "fuck with the system, shoot yourself in the foot".
Human diets are becoming less diverse, a new book warns
Back in the day, I was on a yahoo group that had the REST evangelists pushing for how REST maps much better to consumable APIs than the enterprise nonsense that SOAP/WSDL/WS-* and all that created.

The SOAP people disagreed because they wanted everything defined up front between parties, out of band and then the enterprise companies started selling "tooling" to over-engineer and "manage" this nonsense.

Soon there was "governance" introduced so that centralized control of APIs could be configured and managed. Of course, the different implementations couldn't interoperate, so there was classic "supplier lockin" to your chosen Enterprise-Ready WS-* infrastructure (tm). WS-Addressing introduced resource addressing over XML over HTTP that overloaded the equivalent of a URL. Just one example.

REST in general (HTML/JS/HTTP in particular) has proven to be scalable, understandable, and implementable, without all the associated nonsense that WS-* dragged in.

Want encryption in transit? TLS provides that.

Want caching of results on either client or server or intermediate? HTTP Etags and headers provide that.

About the only thing that REST over HTTP doesn't provide is sessions, but JWTs and OAuth now handle most of that.
I do not believe that in a programming language there is any need to specify if a parameter is passed by value or by reference, and requiring the programmer to choose this (like in Pascal, C and derived languages) is a misfeature.

The right way to specify parameters appeared in the DoD IRONMAN specifications, which were first implemented by the Ada language.

There are 3 kinds of parameters, in, out and in-out, and this is what the programmer must specify.

Any of them may be passed by either value or reference, this is transparent for the programmer. E.g. when an in-out parameter is passed by value, it is copied to the parameter location (which might be a CPU register or registers, or a stack location) before calling the function and then it is copied back after return. For "in" by value there is only 1 copying, before function call, and for "out" by value there is only 1 copying, after function return. (In many cases the copyings can in fact be no-ops, e.g. for register variables.)

If implemented correctly, there is no observable difference depending on how the arguments are passed, except in timing.

The decision to pass by value or by reference must be taken by the compiler, because it depends strongly on the target CPU, i.e. on the relative costs of copying and indirect addressing. Even for 2 Intel/AMD CPUs from different generations the optimal decision can be different (i.e. the length threshold for the size of a structure/class to be passed by value or by reference can be different).

For external functions, how to pass the parameters should be determined by the ABI for that processor family, also taking into account the typical relative costs of copying and indirect addressing.

There might be some very seldom cases when the programmer could increase the speed by choosing how to pass the parameters instead of allowing the compiler or ABI to decide, but if indeed such a decision could have a measurable effect on performance, it is likely that inlining the function or rewriting that function in assembly language would have an even larger effect on performance.

Even in C/C++, the apparent control of the programmer on how the parameters are passed is just an illusion, because the performance is mainly determined by the ABI, which decides, depending on parameter size, whether the parameters specified as passed by value shall be passed on the stack or in registers and whether the return value shall be passed by value or by reference.

Therefore if a parameter is considered by the compiler as too large, specifying that it should be passed by value will have no effect on performance, because it will still be passed as a stack location and addressed indirectly.

The lack of 3-way parameter specification has caused a lot of unnecessary complications in C++, like the distinction between constructors and any other functions (which is needed because in C/C++ output parameters are assumed to be in-out, they cannot be specified as out) and the need for both move & copy constructors/assignments and also the many other tricks that are frequently needed to achieve move semantics.

I'm not sure I would call it a weakness. Performance vs expressiveness and maintainability will always be a trade off. It could be a weakness, but it's just as likely that it was a deliberate trade off.
My favorite was Robert Hittel bookseller in Fort Lauderdale growing up in the late 80s and 90s. What a thoroughly magical place..
Look at how authoritarian the lockdowns in Australia, China, and various other Asian countries were. It worked, unlike the weak lockdowns in Europe. Look at how authoritarian governments are, like Russia, Turkey, any country in Middle East, Belarus, Myanmar. Safety (for the ruling tribe) sells, as does security theater (post 9/11), but its not unique to West. Nor is it useless (if it were, it would simply not exist).

With the popularity of grpc and thrift I've not seen many cases where REST is needed for internal communication. I understand it's required for external communication though. Grpc and thrift are kind of the opposite direction APIs are taking (or have already taken) as in don't we hate RPCs? We do but speed and efficiency are much more important for internal comm (and binary protocols are just one of the factors at play here).

Something does not compute. $1000 should be getting them ballpark 10'000 kWh of power. That is 14 kW of constant power use. Typical largest residential GSHP over here is 15-18 kW of heating at 4 kW compressor power. (usually COP in range 4-5 is specified at 0C input, 35C output) So unless the GSHP is woefully undersized, the house is terribly insulated and the resistive booster heater is running at full tilt, something is wrong with those numbers.

For saving money on heating the first step should be to waste less heat rather than making the wasted heat cheaper.
Bitcoin is money now? I feel that the one thing we've definitely established so far is that it is absolutely not a viable currency.
I am stating the truth as I see it, that's all. It's not some ideological screed against capitalism, it is literally just me describing reality. Reality does have sucky parts and I try to see them as clearly as I see the good parts. Some people call it "ranting", i just call it seeing clearly. It doesn't mean I have a solution to the problem I described, or that I don't engage with the real world. It literally just means I do so while making an attempt to see things as clearly and truthfully as possible. I don't want to get into the tired old debate of "capitalism good or capitalism bad", it is simply too narrow a lens to view everything through. In my view, the problem isn't even about capitalism, its just a manifestation of some of the uglier sides of human nature and competition for social status in the face of actual resource constraints in the world that mean we have to compete for who gets how many resources. Of course the root problems exist no matter what economic system we use.
