Decarbonizing aviation will probably be achieved via conversion to using liquified hydrogen ("LH2") fuel.

It is not clear whether existing airframes can be retrofitted to burn hydrogen. There is not room in the wings for LH2 fuel because, despite its extreme mass-energy density, it takes up much more space. Carrying it inboard on passenger flights might be seen as a safety hazard. Most likely, LH2 would be carried in nacelles slung under the wings alongside the engines.

New airframes may use fuel cells to drive electric turbines in preference to burning H2 the ordinary way.

Once LH2-fueled craft enter a route, kerosene craft will be unable to compete there, because the lighter fuel load allows for more paying cargo in its place.

Major airports will electrolyse H2 from water on-site, and bank LH2 in underground tanks. A big airport will have huge solar and wind farms around it, feeding in power for that. They will represent a very substantial part of each nation's generating capacity, and the LH2 much of its storage.

In the nearer term, there will be a massive demand for synthetic kerosene for the current fleet.

I struggle with this - I tend to agree they will trend lower, but will still be high for the best engineers.

Most high paying jobs pay well because of leverage. Private equity/investment bankers make decisions to invest huge sums of money. The people who make those decisions get a small cut. Similarly, consultants make decisions that steer entire companies, in exchange for a small cut.

Software is unique vs many other jobs because it has a lot of leverage. An afternoon where I write a few lines of code can impact billions of people - this is why software engineers get paid a lot.

Where it breaks down is that only select few software engineers work at Google. There is a lot of software that does not impact a lot of people.

I could see either

a) A shift toward long hours, like finance, where software engineering is a commodity and the highest paid engineers are simply the ones who are willing to work the most

b) A shift of the median downward, but comp among the 95+ percentile of engineers staying the same with competition among the highest leveraged companies.

Right but this fix was on the “qemu 9p server”.

On WSL you would be using the “hyperv 9p server”.

Same Linux 9p client in both cases but that’s not where the fix was.

Reasonable question but the answer is still no.
Do you have a source that this is a "fat finger" error?

I've had contractors publish my code to public Github repos to showcase their work for their next job. Even after emailing them multiple times, I kept finding my code in github with companies emailing me asking for a referral to this person...
I wondered about this exact risk as I learned about the "overemployed" phenomenon. It feels like a matter of time before credit bureaus offer this as a service to the many corps that already pay them for credit checks. It's hard to be legitimately employed without a data trail these days.

So I have a theory as to why we were able to get away with that in the past, but can't really any more.

The approach of letting applications just allocate as much memory as they wanted arose in the era of primarily 32-bit operating systems. And that meant that, at a process level, in practice 'as much memory as you want' capped out at 4GB (or 2GB if you are Win32 because... Windows reasons).

And so when you're running 32 bit processes on computers with single-digit-gigs of physical RAM, and multiple-digit-gigs of disk space, and single-core processors, letting processes treat memory as 'all you can eat' and swapping out excess allocations to disk is going to work out fine. Your processor can only be running one application's code at a time, and a significant fraction of that application's entire address space can all be paged into physical memory at once, with the full amount not taking up too much disk space, so for the most part you can get away with just treating 'process address space exhausted' as being as good a signal as any of 'out of memory'.

But now we're in 64-bit land, address space exhaustion is no longer a thing. If you just allow programs to keep allocating RAM until they run out of 64-bit address space, to a first approximation, 0% of your application's maximum address space will ever be able to be paged into physical RAM, and you will need several exabytes of hard drive space to hold what's paged to disk.

So the problem is we now don't really have a natural limit akin to the 32-bit address ceiling to impose on applications who want to allocate memory, and it means we're instead put in the position of having to come up with policies ourselves. Stuff like setting a memory limit on a docker container. And so we wind up having to actually now think about and answer the question, 'how much memory should we let each process on this system allocate?'
Right, this does seem to be a cyclical thing.

My point is that it would be extremely weird for every developer to simultaneously exit the VR market immediately AFTER Alyx gets multiple GotY nods and new hardware sells multiple millions of units.

And yet, apparently, this is what happened. On some level I suspect FB buying up a dozen of the biggest VR game studios and letting them languish is a big part of the problem.
In the UK there's a set of criteria (IR35) that attempt to codify the distinction. The hiring business has to make the assessment.

One of criteria is right to subcontract and freedom to work with multiple clients.

If they get it wrong, they're liable for taxes, not the Contractor.

HMRC, the UK tax body is responsible for this, and therefore it is an utter mess in practice and has had chilling effects on the UK IT consulting market.
Some of my graduate level work was in Tcl, and my first job used a lot of Tcl. I have fond memories of the time, and Tcl is one of my favorite languages to this day. It's power and flexibility are fantastic.
Isolation is indeed a cornerstone of what makes this style work, but "let it crash" is another one, and just as important IMO. "In this language crashing would take down other connections" does not make it safe to continue without crashing and doesn't remove the need to crash and recover, or something equivalent to that - rather it's an argument for finding a way to separate connection tracking from more complicated logic that might get into unexpected states.

Do you find these condescending tactics work well when you're trying to change someone's view?
I think "can" is doing a lot of heavy lifting there. Sure, it's theoretically possible, but I don't think it's at all realistic to expect most Americans to change their attitudes toward consumption. I think the only way to do that would be to tax everything to the point that most people just couldn't afford more than basic consumption. But that's... pretty regressive, and no politicians would survive more than a term (if that!) without repealing those taxes.

Otherwise, what motive do most Americans have to reduce consumption? Even people who believe climate change is real and are worried about it likely barely move the needle. That's before we even consider people who don't believe or don't care.

Now, I think we can reasonably meaningfully reduce the amount of pollution we produce per "unit of consumption" such that consumption levels could remain relatively unchanged, but still allow us to save the world. Whether or not we can get there, with powerful short-term-thinking, status-quo-loving lobbying groups hindering progress every step of the way, is another matter.
In my mind, Tcl _is_ a lisp. Admittedly, it's pretty far out on the family tree branches, but the overall structure feels very lispy to me.

Of course that is not applicable to 'boards' and 'CxO'. Quick search suggest some of them sitting at at least 2 'boards' or also 'partners' or something.

It's only Narcissistic when the victim gives up something up in the process of becoming your dependent-- like a spouse forgoing a career to raise your children, and then you threaten them with a divorce that will leave them destitute and unable to provide for themselves. So they stay trapped in an exploitative arrangement.

What you're describing is the opposite-- a very entitled (and I daresay Narcissistic) interpretation of charity.

Weird how this came out on the day I bomb my probability test. T_T
The short but useless answer is yes.

The longer and hopefully less useless answer is that "executive/startup coach" is too general regarding your desired outcome(s) so it would be difficult to identify prospects for your consideration. "Relevant price point" also needs to be nailed down.
I'd add that in materialism, intelligence is a product of activity in neurons, and thus it is 100% about DNA; however in spiritualism, where mind is a part of soul, intelligence is also effectively "inherited" because you carry your mind with you and the body it gets attached to is determined by the degree of development of your mind.
That's a weird logic. So it would be constitutional to outlaw gunpowder?
As an RF engineer, this is a very creative application of mmW and I hope can be successful, but is not without very significant challenges which the company has made no claims to have solved. The issue is, mm-waves (and all high frequency RF really) are very sensitive to distance and losses. As a random example [1] gives some numbers for theoretical and precision machined waveguides in these frequencies. In the very best case we're talking about 0.03dB/cm loss. That means in the first meter of ideal waveguide you've lost half the power! And not just disappeared, you just dumped 0.5MW into the pipe itself, meaning it would likely melt within minutes. Meanwhile, their concept is to bore 20km into the earth.

The only way I could imagine this working is to lower the gyrotron itself down the borehole, but there's presumably tradeoffs of physical dimensions and output power that make it challenging. Again maybe not impossible, but there's no indication they've made fundamental advances in miniaturizing the source, or producing lossless waveguide.

Related, another interesting company I came across is Petra [2], who is doing something similar -- plasma/heat based non-contact drilling. But because they fracture the rock instead of vaporizing it, there's essentially gravel/sand leftover which is hard to evacuate from a deep vertical shaft, hence their focus on power/fiber trenches not geothermal.

> on average people would have lived another 14.5 years if they hadn’t been infected

How did you get that from your Pew Research source? The math on 5.5 million life-years lost over 330 million Americans works out to 6 days per person. Are you referring to a different source?

The one I found regarding US Covid deaths in 2020[0] shows more or less the same distribution, with over half of the 378k deaths being over age 75. For your statement (that the average person who died of Covid would have had another 14.5 years to live to the average life expectancy) to be true, the average Covid death would have to be roughly around 64. The 55-64 age group of Covid deaths in 2020 was under the 20th percentile, so I can't see how that works out.

In a world without state-mandated social distancing, perhaps the most vulnerable would have distanced on their own, avoiding getting sick and breaking the healthcare system, and the younger, healthier people could have lived on as usual.

They did the opposite and now that is PostgreSQL for CosmosDB. Can’t make this shit up.
Sounds like something we could check empirically. Some cosmic rays are protons from outside of the solar system. We could capture those and compare them with local protons to see if they're actually the same kind of particle. (We can check if two particles are the same kind or not by seeing what happens if we try to put them in the same place. If they're both protons, they should refuse to be put into the same state due to the Pauli exclusion principle.) As far as I know the experiment hasn't actually been done, though.

Not only does it exist, Equifax itself offers this as a service, Equifax's offering is called The Work Number.

AI recruitment software is 'automated pseudoscience', Cambridge study finds
The US tax authority (IRS) has a similar set of rules; if you can set your hours and working conditions and have your own equipment or tools it justifies not being an employee. There are of course important corner conditions like hiring a contractor who operates some machine you own.

In general, though some people prefer to be contractors, these rules are in place because some employers try to classify de facto employees as contractors to avoid paying taxes or providing required benefits. Google, FB etc have complex contractor rules for their third party contractor agencies to steer clear of that and make sure they save on taxes and benefits.
The company I work for integrated with Equifax. I ended up in a meeting with their work number folks where I had to explain that there was no reason for us to share (e.g.) SSNs with them. Suffice it to say if your personal data is in any platform that tracks employment or income information that you are directly vulnerable in the event of a data breach.
I was in car sales. Top performers were caught borrowing used cars for nights out, secretly loaning cars to favorite customers for long period of time, buying tradeins secretly off the books, crashing cars while basically driving recklessly while transporting company cars to customers or off-site facilities, and not fired.

Low performers were fired because they answered incoming calls poorly twice in a week.

So it IS possible top performers were allowed to have side gigs and not fired at Equifax.
Equifax doesn’t care about that lol.
Spanner offers that on GCP, and I believe CockroachDB offers something similar cross-cloud.

org-roam or more generally org mode in emacs is less fixed in it's page structure than logseq. I think outliner is in fact the correct choice for logseq. You cannot move outside of the structure logseq provides for you for the files. org mode in emacs allows you to use any structure you want.

So I think while outliner might be misplaced for emacs it is not for logseq.

Weird. The one near me has some stairs as well as the escalators (and I think a lift nearby too), so you can just go straight up to the restaurant and then straight out if you want...

Note that security guards can be structured as contractors despite obviously not being able to choose where or when they work. There's a big list of things that "weigh in favor" of one status or the other. There aren't definitive answers unless you've recently won a lawsuit against the government (which always wants employee status for everyone).

Thankfully I’m seeing some negative responses here. I think there’s an effort by to destroy our societies. It’s clear that cocaine is harmful to people, and legalizing it could remove many criminals from jail. The argument that “people use it anyway” could be transferred to any crime. We’re not decriminalizing anything because of that reason (cost/benefit analysis). Many fights for the right thing are a constant and costly battle. It’s a bad excuse.
I agree with many of your points, and absolutely with the point that we should align economic incentives. I further suggest that instead of allocating tax dollars to such research programs, we just cut those taxes. If economic incentives are properly aligned, then there will be plenty of profit motive for private efforts to research lower carbon cement and whatnot.

Unless you think that we can have a second Manhattan Project and dedicate half a percent of GDP to that end and get something usable on the other side ;-)
Just curious why Zig was chosen compared to the other languages out there for high performance computing like Go, Rust, Nim etc. Was it just because you were familiar with Zig or were there deeper reasons related to the programming language?
I use Sublime Text as a simple note taking app (love the speed and tabs). Didn't know about Obsidian and was exited to try it after reading about it today, but the simple fact that Obsidian loads a fraction of a second slower than Sublime, may be a deal breaker for me.

Doubling down:

Suppose I were a Fed bank president who wanted to profit from advance knowledge of changes to rates.

When I know rates are going to decrease, I buy a growth ETF, like VIGRX, or a tech index like QQQ. Or I buy a bigger house, safe in the knowledge that prices will go up and I can refinance soon at lower rates. And if options are allowed and I want more gains, I buy calls on ETFs like the ones I mentioned.

When I know rates are going to increase, I instead simply get out and hold cash. Or if options are allowed, I buy puts on QQQ, or at least sell calls.

In all of these hypothetical transactions, I have benefited from my advance knowledge of rate changes, without picking a single individual stock.

I can even make an argument that these diversified trades are more reflective of rate changes, since those changes have broad impact across the economy, whereas specific stocks are confounded by all sorts of idiosyncratic things. Using these ETFs, I average out more of the random variables that aren't "interest rates".

So I don't see how this new rule, which bans stock picking by people at the Fed, matters a lot. These people don't regulate specific industries; they set rates. About the only exception I can think of is bank stocks: Maybe the Fed's interactions with specific banks are significant. But apart from that -- this seems good for appearances, but does it actually accomplish much?

For congresspeople on the other hand, or for people in regulatory agencies, I get it. You don't want a regulator siding with one company over another, or, indeed, from being overinvested in whatever sector they're regulating ("Let pharma get profits at all costs! What do I care about opioids?").

But for people at the Fed? It's not a crazy rule, but I also don't think it does much.
