People tend to confuse the passivhaus idea with other energy efficient methods. The passivhaus idea is that if the building has sufficient insulation and is air tight, you can use the air from the heat recovery ventilation system to do any required heating cooling. This simplifies the mechanical part of the system.

As a result, such houses are very well ventilated when it is cold outside. Mould is not a problem. The potential problem is instead excess dryness in places where it gets very cold.
Not a nuclear physicist, but IIRC sustainable fusion requires three factors: time, pressure, temperature. So far, you can basically choose two of them at a time, and much research goes into having all three at the same time.

Needless to say, but it also requires loooooots of related research, eg materials to handle the magnetic flux, temperature, etc etc etc.
IMHO A lot is hanging on Monero's ASIC resistance, version coming up this month: true decentralised hashing power is essential to the concept.

But still a question of if it will make financial sense. Assuming this generates heat and drives a steam turbine, solar, wind and battery is likely to be cheaper than just the steam turbine and the transmission costs, never mind the fusion bit.
The API is not not SOAPish, it just uses XML. They probably choose it so that they can use XML Schema to check incoming data (which is exactly the right decision here).
> The reason that you don't have intra-module distributed build is because the intra-module code dependencies are implicit - there is no developer-defined partial cross section of the code, all of the code needs to be pulled in and semantically evaluated as a unit.

And this seriously somehow doesn't seem like a problem to you? My massively distributed (to AWS Lambda) C++ build compiles at the speed of the slowest single translation unit. You seem to be optimizing for serial compile performance, but if you truly want speed you have to go parallel. These explicitly-managed "cross sectional sunsets" are what makes this so easy to do with C++.
There can be of the same nature if there is not enough air circulation so that the walls get mold.
I don't think it is, it seems more like very easy access to capital was (mis)used in some specific cases to build very capital intensive businesses that only really scale linearly with additional capital invested (where they're supposed to scale exponentially obviously).

It's more like an inefficiency within the VC system that has been exploited and lots of money wasted, and hopefully lessons are learned. I don't think it says anything much at all about the fundamentals of the broader industry.
That would be post-split HPE, not HP.
I'm the reverse. I use Mint and my wife uses Ting. Having previously been with Ting, I've cut my monthly bills in half, from ~$30 to ~$15, with 3GB of data a month, which is more than enough for me. Granted, with Mint you have to prepay for a year to get that rate. But it's on the T-Mobile network, and I can't complain about the coverage!

We already are. Instead of gravity, magnetic fields are used to compress hot plasma and cause it to reach very high temperature levels to allow fusion.

Temperature is basically atomic/molecular movement and the more energetic the movement the more likely that crashing nuclei will react and fuse.

There are currently two major magnetic field designs:

- Tokamak, such as ITER [1]
- Stellerator, such as Wendelstein-7X [2]

Starting a Podcast: Anyone Interested in Being a Co-Host?
I've been thinking about starting a podcast for some time now. However, in my experience podcasts are a lot more fun when there's more than one person speaking.

I've been listening to podcasts regularly for many, many, years now. Programming is something that I'm really passionate about. Podcasting would allow to do both: contribute back to the community and learn new things.

Although my preferred topic would be around Python, I'm open to other areas, such as: DevOps, Programming in General, Full Stack, Security, etc. We can even mix it up. Is anyone interested in giving it a try?

For context, here is a list of some of my favorite podcasts (you'll know if we have a match in interests, although that's in no way a requirement):

- CoderRadio [ gone now :( ]

- SecurityNow

- Python Bytes

- The Python Podcast.__init__

- Talk Python To Me

- Test&Code: Python Software Testing & Engineering

- Programming Throwdown

Yes, you can't change the genome in all the cells of a body. Whether this is necessary or not depends on the disease. For example, for certain conditions, it would be enough to edit some bone marrow stem cells, then put them back into the patient, perhaps at the same time as getting rid of most of their existing bone marrow with chemotherapy or radiotherapy. Another example is editing a specific organ only, such as the retina or the liver.

If Boeing keep this up, I am wondering who's out there writing the book called "Boeing: The giant stall"?

PS: Credit me for the title if ever! :)
Generating the necessary heat and pressure is already possible. The problem is keeping the whole process stable over long periods while getting more usable energy out of the fusion than is needed to maintain it, if I remember correctly the experiments so far had extremely short durations.

Apparently Iter was designed to make sure the energy balance works out, but we'll see.
Same goes as for food: buy local, short supply chain etc. Meaning also not every single thing is available, but at least you know what you get and where you got it from. And obviously: depending on where you live there won't be any people making what you want..

In diving there is a repeating patter of wrecks being discovered and rediscovered which usually follow the same pattern.

A researcher is looking for a famous wreck and locate local fishermen who says they know where it is. They go there, find the wreck, write about it in a journal, and then it get forgotten. A new researcher goes and look for the same wreck and again goes to local fishermen who points the researcher to the wreck, a book get written and the wreck get named after the now official discoverer.
parent says they wants to use libc++ to catch more bugs. Which is a reasonable use case.
it becomes dry inside no matter how you ventilate or heat, if it happens through a vent system with heat exchanger, there are built-in humidifiers for these
I agree.

A classic example is the story of the semiconductor and radio. The popular history said that the point-contact transistor was invented in 1947 at Bell Labs and started the age of semiconductors. But do you know that Russian physicist Oleg Losev (also a pioneer of LED) discovered negative resistance in zinc-oxide diodes in 1923, and built solid-state amplifiers, oscillators, regenerative and superheterodyne radio receivers, 25 years before the transistor, but starved to death in the hunger during Nazi Germany's invasion and forgotten? And do you know that at the same year, 1923, American physicist J. Edgar Lilienfeld (also a pioneer of electrolytic capacitor), invented the first prototype of the Field-Effect Transistor, but due to technical limitations and his failure to publizie his researches in big-name journals, remained unknown for a long time?

At the end of the day, I think some simplification and ignorance is acceptable in entry-level/popular history books, but in more advanced-level history books, all the known co-inventors/co-discoverers who have made contributions deserve a mention.

Wikipedia has a good "list of multiple discoveries".

It's been made to work, as I recall from a visit to Culham, the problem is keeping it there. We can 'do fusion' briefly, and more expensively than the value of the energy produced.
Fusion has the same advantages as fission but the disadvantages are reduced to a minuscule amount.

CO2-neutral, stable energy generation independent of weather, season, time... with amounts large and stable enough to be independent of storage solution.

Wind and solar need to be regulated because intensity varies. They are location dependent (German North produces a lot of wind, but there's no feasible way to bring it to the South...)
Nuclear Fusion has a really interesting history. There's a good book called A Piece of the Sun I highly recommend to anyone interested in the subject. I was surprised on just how much money has been spent by so many countries on research, how different designs have evolved and just how much politics has influenced its development.

There's nothing wrong with over-insulating (although at a certain point it is no longer economical), but you need to ensure the house is ventilated to prevent mold.

You also need to ensure you choose the correct building materials, so they can ventilate themselves. Modern building science says there should be a continuous airtight wrap around a house with insulation either side. The interior insulation ventilates to the inside, and the exterior ventilates to the outside. What you don't want is multiple airtight layers as that could cause it to become moldy inside the layers.

Passivhaus houses will almost always have a heat-recovery ventilation system. These will bring in fresh air and take out stale air - like a bathroom fan. But they also exchange heat from the outgoing to income air in the process. Typically 80%+ of the heat is recovered (you can get systems that are 95% efficient). They run at a low speed so consume minimal electricity (typically under 100W for small houses) and don't provide a noticeable draft like air conditioning or forced-air heating. They have filters to prevent pollen and other contaminants from entering your house, so for allergy suffers they are a big plus.

I live in a cold climate in an apartment built in 2015, which is well insulated and has this system. Even though it has been below freezing (currently 8c) outside, we haven't yet needed to turn on our heating because of how well the building is insulated. We do actually have a typical vented bathroom fan, but everything else (kitchen hood and dryer) are unvented, so we keep all that heat inside.
The last decade has seen global monetary policy create a situation where cash is very cheap (i.e. many central banks are now offering close to zero interest rates and some have actually seen negative interest rates).

That cheap cash then finds it's way into assets like stocks and housing with that cheap money putting upward pressure on those assets.

In that same climate we have seen a decade long stagnation in wages, next to zero inflation and we are now entering a stagnated and slowing global economy.

With those contradictory growth signals, the real question is how long will that cheap keep flowing, as it is the only stopping those artificial asset bubbles from popping.
Smartphone head lump more substantial in young adult age group
I remember seeing a very different approach with a very similar goal in Vietnam.

In Hanoi, many houses have a small greenhouse-like glass structure on the roof. The greenhouse has a chimney. When the sun is shining, it gets hot in the greenhouse and the hot air escapes through the chimney. A hatch through the roof into the greenhouse draws new air from below, essentially creating a passive, sun-powere air-flow through the whole house, bottom-to-top. Usually some windows on ground level are left open to let air in.
Having the most fun before death, everyone and everything else be damned?
That's indeed a big if, but even if it ends up being cheaper to use solar for most applications I can imagine fusion power would be a nice thing to have locally around major production centres where the power demand is much higher.

Solar is great for decentralized grids where one's neighbour basically buys excess power from you, but transferring gigawatts of power from a large amount of solar panels to something like a major industrial area /might/ be trickier.

> Actually, there as an argument that it is not good for Airbus at all because it will risk the stability of duopoly between Boing and Airbus.

I like thinking about this in a sort of hypothetical Sparta. Sparta had two kings from two different royal lines.

Suppose you're one of two kings, and the other royal line experiences some sort of dynastic hiccup. This inevitably happens to everyone.

A popular strategy throughout history is to capitalize on that hiccup by exterminating the existing royal line, or at least driving them out of power so you can take it yourself. As a king, you are ideally positioned to do this. Maybe you can take both thrones and be the double-king. Maybe you can put your cousin on the second throne. Maybe you can put a flunky on the second throne. Maybe you can get rid of the second throne, leaving yourself as sole king.

But once you do that, a precedent has been set. Your line will eventually stumble too, and it is likely to suffer whatever fate befell the other line the first time. Another strategy you have, back when the rival line first shows weakness, is to stake everything you have on your commitment to upholding the Spartan way of life as expressed in the dual kingship. Give rousing speeches on how unthinkable it would be for anything about the current setup to change. Throw all your considerable resources into supporting the king on the other throne, no matter how weak his position might look.

If that sticks, the other line is likely to remember that you were there when they needed you. But even more than that, you've just established that the dual kingship, and the two families who fill it, are an integral part of the culture, never to be questioned. That tradition may ultimately prove more helpful to you than any personal support. And it has such obvious benefits to the other royal line that, going forward, they will likely support it just as strongly as you do.

On this analogy, the problem with disturbing the Airbus / Boeing duopoly isn't that Boeing might start to compete with Airbus, provoking an arms race. The bigger problem is that (as you mention) some other company might start thinking they can make airplanes too, and who knows what could happen then.
The point is that these extra Euros, if they were any significant amount, in the local market would drive the demand for goods up, along with their prices. And then we'd be buying the same amount of stuff, just more expensive.

Surely things like rent take longer to reflect an increased demand but they do eventually catch up.
Facebook Reveals New Data Leak Incident Involving Groups' Members
I ran a ~ 0.5 PB Ceph cluster for a few years, on quite old spinning disk hardware (bought second-hand.) It was great: it just worked, coped very well with hardware failures, told the operator what was happening. An extremely solid, well-engineered system. My thanks to the Ceph team :)
Time has really been the killer. It’s been well understood since the beginning (a brief 60 years ago) how to make plasma hotter and more dense. We’ve learned about limits to pushing these two, but at the end of the day if confinement time was infinity then fusion would be trivial. The thing is even 10^-6 Torr conductive particles squeezed by a 1 Tesla field still like to drift outward and hit the wall. I cannot, in short form, explain how complicated this problem is. However there are no apparent show stoppers.
I don't see it as two kinds of null, there is a null value, and then there is the fact that no value has ever been defined, which is undefined.

It can be useful to have the latter case distinguished in a dynamic language because it can enable certain powerful patterns. At the end of the day, compressing both these cases to a single concept of null would be lossy. This may have certain advantageous implications for simplicity, but you're trading that off for language power. Which you favour more of course depends on the usecase.

Its also not an option. Renewables wont hold up to scaled demand and nuclear fission is demonized, there is no other viable technological path.
It's refreshing to see that the financial Shenanigans SoftBank was playing with WeWork and even Uber backfired like that in the end.

Manipulating pre-IPO valuations as aggressively as they did was just insane.
It's not my fault that the entire conservative and libertarian movement decided to adopt the most idiotic possible stance and stick with it long after it was obvious to everyone that it was a low quality lie.

Am I now supposed to pretend that didn't happen and naively assume that those same people are genuinely curious about the impact of mining rare earths, or wether gas backup of renewables is better economically and environmentally than burning coal, or about bird deaths from wind turbines?

No thanks, unlike the people who believe this nonsense I'm not a complete chump. Maybe you're only pretending to be ill informed about renewable energy, but either way repeating talking points you learned from climate change deniers isn't in the least bit convincing.

Yes the guy in the video sounds like he's talking to very slow children. That's how you talk to people with opinions unmoored from reality. He's right though. Tesla didn't look at whether EVs were possible and say "this doesn't exist therefore it never can" they looked at the physics of it and will be creating large amounts of electricity storage that is cheaper and more environmentally sound than what came before.

Just repeating "this isn't possible" when lots of domain experts think it will be isn't convincing. Just like denying climate change wasn't convincing, just politically convenient.

Netflix isn't the only one contributing back to Netflix. In his interview with Bryan Lunduke, George Neville-Neil[1] explained why it's very much in the interest of companies like Netflix, Juniper, and others who base their systems on FreeBSD to contribute back all "infrastructure-level" changes they make: it helps the FreeBSD community and also reduces the amount of sysadmin overhead when it comes to upgrading to newer versions of FreeBSD. Only those things which are unique differentiators for their business are withheld and kept proprietary. For Juniper that's going to be a lot more than Netflix but it still disproves the GPL puritans who rip on BSD/MIT/Apache2 licensed software as being black holes from which companies won't contribute back to the community.
