> Given these paragraphs and the name "thermophotovoltalics", that this is about solar power seems like a reasonable conclusion to draw. Also, googling around I am seeing figures for steam turbine efficiency of between 40 and 80%. How sure are you this is not about solar cells?

That it's not about the solar cells people in the comments mean? Very, the paper and citations talk about furnaces, and the temperature this operates at is 1200C. This isn't something you'd stick on your roof.
My wife and I joined our bank accounts a few months before the wedding. We consider that to be our true wedding day. We got to Admiral status with Vanguard much quicker this way. Also, I intend to spend 100% of my time with her once we retire and I can't wait. My parents and her parents have been living like that for years.
Paper can't be recycled forever either. Of course paper is biodegradable so it's not a major problem
Yea this is super impressive but also a little crazy. I’ve never heard of a company (yes, even bootstrapped ones) say that SES or Mailgun were too expensive - if anything, it’s that they’re dirt cheap.

Cost aside, all that time hacking your own ESP takes away from investing in your core business.

+1 on pricing - you provide an awesome service and you should charge what your product is worth. I think it’s natural to start out cheaper to establish yourself but when your margins are so tight you need to hack your own ESP, time to examine pricing :)
The idea that animals only eat food that humans can't consume is very strange. The animals get fed whatever is cheapest on the market, even if that involves burning the rainforest and depleting its soil permanently or feeding them skittles.
Ghetto doesn't imply violence or crime to me. Per Wikipedia:

This is relatively misinformed piece of writing.

There is little to no reason why high performance RISC-V implementations can not achieve performance comparable to modern "CISC" cores.

As other commenters have said, VLIW doesn't suddenly make the problem go away and no amount of compiler magic is going to fix the fundamental issue that memory access on a modern processor is highly non-uniform and scheduling is not something that can be done statically ahead of time.

RISC-V is designed to be extended with complex instructions and accelerators and that's the scalable part.

What Chomsky points to as a cause (wealth distribution) I might argue is an effect. Those few with the ability to do so, continue the growth while others are left behind. Eventually for the wealthy too the growth will stop. This leads to violence and large scale violence resets the wealth inequality (temporarily). Peace depends on continued real growth.

This appears to be a regular column in the Guardian called “Pass Notes”, which takes this format to discuss... anything, really; the previous installment is about the emerging practice of stopping teens from congregating in places by installing lights that highlight their pimples.
I believe the 8 year warranty is driven by the federal requirement to warrant emissions systems for 8 years/80K miles. I think that all EV manufacturers are providing at least that level of warranty for battery and electric motor and think that it's likely linked to the federal emissions control warranty requirement.

There's a school of thought that past the warranty period, the traction battery is likely going to last the lifetime of the vehicle, by definition (in that when the battery dies, there is likely no economically sound way to replace with a new battery, so the choices are fit a junkyard battery or junk the car).

If by many then you mean "many voters" then yes. Most of the dyed-in-the-wool alphabet soup / military types, the same ones who would be deep state material, are pretty ardent republicans. Mueller, for example, is a lifelong republican who was a Marine Corps officer in Vietnam -- solid freemarket GOP type.

Why is this being downvoted? Are those living in the liberal Northeast US ever proposing to reduce heating? Not much. Read the comments here — using “less AC” appears more frequently than “use less heat.” My point is that you have a point. Colder places lament the AC use of hotter places because they aren’t significantly proposing to limit their own quality of life, but the quality of life of people that don’t vote like them.

Is it me or maybe you also have doubds about LoRaWAN use cases? (LoRa is physical layer, way of encoding bits with rf, but you need protocol. LoRaWAN is open standard, which is being implemented and used by TTN community)

So for me main drawback of LoRaWAN is limited number of ACKed packets (gateway which can talk to thousands devices can use only 1% of airtime (simplified) and you have to divide it by number of users https://www.thethingsnetwork.org/docs/lorawan/duty-cycle.htm...), so you are allowed to have 10 packets per day. Any other data can be send in way called " send and pray"...

Would you build industrial device for telemetry while you can not be sure about your data? For example energy monitoring with 15 min periods. You can't be sure that your data arrives.

So ranges presented here is matter of luck but not reliable link.

Maybe ISM band limitations should adopt to LoRa which is more resistant to errors.

Or protocol should be changed (symphonylink has protocol for unlimited ACKed frames, OTA etc)

Just my 2 cents.
I was also thinking the same thing after glancing at the table of contents. I remember working with C++ while studying at grad school with instructions by two professors who quite loved the language. Even though I enjoyed the language and its STL very much, the mess of its build system and linking to other libraries is what comes to my mind whenever I think about C++. This is exactly why I never touched it again.

Cargo does a fantastic job for Rust in this regard. Rust won me over.

Something incredible just happened.

After a half century of jaw-boning about the need for renewable "green" energy, we now have a repeatable scalable tech template similar to the [oil well + refinery + piston engine] or [coal mine + pulverizer + furnace + turbine] tech templates that scaled fossil fuel energy. It is: [wind turbines and/or solar PV panels + lithium ion cells].

By repeatable and scalable tech template I mean something that no longer requires non-incremental forms of R&D. We no longer have to think that deeply about it. It's now in the realm of "see that stuff? Build more stuff like that."

The solar/wind+li-ion template can, if scaled, power almost all current human industrial activity with the exception of long-haul heavy vehicles (land, sea, or air) and rockets. Those are important things but they're collectively less than a quarter of all fossil fuel use.

The key is "if scaled." We are going to need more lithium. Good news is that it's not really all that rare. Bad news is that until quite recently there hasn't been serious investment in getting it. Look at what we invest in getting oil vs. lithium.

That's because until quite recently there hasn't been the demand to justify that investment. Now there is. Lithium prices have exploded, signaling the need for more. The price signals are working. Good.

It's normal during this kind of scaling to have periods where it looks like investment is outpacing demand and vice versa. Demand and supply don't scale at the same rate so you get price spikes in both directions. This doesn't change the underlying reality now in effect.

I'm pretty sure that Tesla alone is over 1% (maybe 1.5 to 2%?) of the US car market. Worldwide is likely to be even higher for electric cars in general.

The thing is that shifts in large markets like this take a long time to really be realized. It has taken Tesla 15 years to go from 0% to over 1%. Their current aggressive plans call to double that in another 2 years.

The real question is what kind of change can they make over the next 15 years. And for that, we need the crystal ball...
How to Interview Engineers When You're Not Technical
It it not really the formal logic that is at fault. In logic you are basically allowed to make any assumption or definition you want.

The problem is thinking a proof can tell you anything about reality which isn't already implicit in those premises.

If we define that X exists, then it is logically true X exists. But this doesn't prove that X exist in the real world.

Blockchain for voting sounds like a terrible invitation to a terrible party. Voting is already a delicate subject which is really hard to secure on information systems. Researchers have spent decades to figure out a perfect solution but came short.

Blockchain has already surpassed its boundaries for multiple reasons. However, voting should be beyond that line. There are many questions that need to be answered before even thinking about using blockchain for voting.

- How will identification work?

- What is the proof-of-work scheme?

- How can you be sure that every vote ends up in the ledger? Transactions usually get lost and sometimes takes few tries to reach to miner.

- Most important property is that not a single vote should be traced back to its caster. Blockchain is all public, how are you going to anonymize everything? IP addresses of transaction owners are already open.

Performance of GPUs has increased quite well over the last 10 years. Number of Cores on CPUs have also increased.

Even if performance didn't improve, that wouldn't make moore's law dead.

You might say that Dennard scaling is dead. But Dennard scaling isn't Moore's law even thought is gets conflated a lot.

Edit:

Compare a GTX 285 to a RTX 2080 ti, the performance has increases more than 9 times over the last decade.
I like The Guardian but hate this format. It's neither informative nor, as I'm guessing it's supposed to be, humorous. Often it's just confusing. Yet they use it for everything.
You're taking a human centric view here. As misanthropic as it may sound, it's entirely possible that this is just a correction in the tiny fraction of the great span of geologic time we happen to be living in. Similar to how the human body gets a fever to fight off an infection, we have the earth heating up to a level destroys the destructive pathogen - us.

I suppose it's possible that we get wise enough to deserve continue on as a species, but at this point I doubt it. I don't see anything in humanity that would lead me to believe it's capable of making the cohesive decisions to remedy the situation. Something else will come along in a few million years and maybe they'll do a better job of it.
Well, you can use whatever extremities of strictness and year of standard for new code (mine is currently c++17 + pretty much every possible warning). And you can keep lower levels of warning for older, or third party code.

In the case of the standard library, the whole library is being hoisted to use <=> in c++ 20. Old code will still work with the latest library of course.
That's quite a list! I'll try you service soon after publishing my latest update and revision.

Interesting approach. Where I work, we use Jenkins for collecting results. That way, for each build of our application we have a history of results for static analysis. Jenkins has good tools for storing and displaying this information, as well as the ability to show trends over time.

The alternative is that you can _only_ appreciate the true state of the world when you are depressed, and everybody else just walks around in a little stupor thinking somehow they and their world matters, when we are all the effect of a run-away accidental chemical experiment.

Preserved fruits and vegetables are extremely cheap and available in the US. Food in general of any type is actually very cheap in the US unless you live in NYC or downtown SF. These prices are for average chain grocers, HEB, Krogers, Wegmans, etc. Not bulk shops like Sam's or Costco. Some grocers also tend to focus on lower costs and will be cheaper than this such as Fiesta.

Frozen typically runs between $1 and $2 a lb depending on what you want. Some cheaper mixes can be had around $0.50/lb.

Canned typically comes in between $0.25 and $1.00 a can depending on brand. The chain grocer near me also routinely has sales on canned vegetables for $0.15/can if you buy 20 or more. A can is typically about 15 ounces. It can make up the bulk of a meal for 1 person, or serve as a side for about 3.

Dried bulk products such as rice or pinto beans are also reasonably cheap though more expensive now than they used to be. Beans run about $0.25 to $0.50/lb depending on how much you buy at once and rice is about half of that.

Fresh produce varies a lot by time of year and location but can typically be had for under $1/lb if you aren't choosey. Double to triple for anything labeled organic.

Meats start around $1 to $2/lb for chicken thighs and pork shoulder and goes up to about $20/lb for premium beef cuts.

I routinely make stuffed bellpeppers (bell pepper, rice, hamburger, tomato, and spices) for lunch and then end cost comes out to around $1.50/lb.

Another off topic? Does this have anything to do with the TRON acquisition of BitTorrent?
> the private torrent DRM garbage. Torrent creators stupidly mark their torrents private or not, changing that flag changes the infohash and you might not be able to access the files with the new hash, it's incredibly hypocritical.

Private is not used for DRM, it's used for security on every private tracker.

> Here's a cute completely irrelevant story, feel free to skip. The phrase "Because Australians!" has actually become an inside joke/catchphrase in our company. See, Aussies and Kiwis (New Zealanders) wake up before everyone else (even before Japan). Basically Australians are the reason SaaS businesses don't have an outage/maintenance window. And a couple of times when we were about to put a server down for maintenance on a late Sunday evening (EU time), someone would shout "Wait! Don't do that!" - "What... Why?" - "Because Australians!"
So after 4 or 5 times this phrase is now used as an ultimate "42" answer why everything has to be up and running 24/7. I even have a tiny map of Australia in my office. I (nor anyone from the team) have never been to Australia or New Zealand, but hey, we're always thinking about you mates [wink]
Well you can't really know even if you go and submit a paper ballot. If you could verify your vote, you could sell it. I don't know if that's still a realistic scenario these days when Tammany Hall isn't literally beating people for votes, but it's a reason why you can't tie a vote to yourself individually.

In theory, if both the burger and the natural gas is domestic, it's fully accounted. The tax is on the natural gas so the cost shows up in the burger.

In practice, it's @#%#ed up, as usual. They didn't implement a carbon tariff, so foreign fertilizer would have been a lot cheaper than domestic fertilizer. But instead of putting a carbon tariff on foreign fertilizer, they gave domestic fertilizer a 90% exemption.

Most “progress” since CL has been very “one step forwards, two steps back”. The interactive development, amazing debugging (don’t unwind the stack), powerful macros, nearly-C-speed (if optimized), great tooling, etc. are mostly kept by other Lisps, but at the same time most every new language in the Lisp family loses some aspect of what makes CL great.

Yes, this. Voatz is holding a lot of power here and I can only imagine how well their solution is implemented. Do state or local governments even understand what they do?
The private flag also annoyingly exists on many public torrents with no good way to override. It is DRM.
I find the position that the real solution to incompetence is to just give people blunt knives to be utterly unsatisfactory. If someone cannot understand how exceptions work for example I have a hard time seeing how removing this massive burden from their minds will result in good outcomes. Being easy to use for people that probably would be better off doing something else is not a solid design principle.

Java went down this route, ah, we will remove operator overloading, that will make it simpler, because nobody can ever write a function named equals which does not do what you expect it to... and the end result is horrible and does not prevent people from doing amazingly dumb things.
Yeah, I need a citation for that as well: As far as I'm aware, significant leaks only happen at production sites, but not the plants.

Also note that natural gas infrastructure can substiture for 'geographical advantages': Germany can store several hundreds TWh that way, which is more than sufficient. Recent claims of power-to-gas-to-power roundtrip efficiency are at 80%, though I've no idea about associated costs.
