There is a number of battery chemistries more cheap and even efficient than Lithium-based, but with lower energy density. High energy density is important for handheld devices, for flying devices, even for cars. But stationary energy storage can be much heavier and bulkier per kWh stored, as long as it's cheaper, and can sustain more than a few thousand recharge cycles.

Lithium batteries have the momentum and are dropping in price because of the EV cars revolution happening right now. When solar revolution will happen i utility scale, the utility-type batteries that will emerge may be seriously different.

I really like this article, particularly this point:

> Wayland's lack of feature parity with Xorg cripples it.

This is something I've bible-thumped Wayland advocates over for years. wlroots is dead-on-arrival in the eyes of smaller DE/WM devs. Nobody wants to update their entire system's display server, and then be forced to rewrite entire portions of userland and the OS just to get their desktop working similarly as it was on Xorg, with less hardware support.

That's a problem. It's something that Wayland advocates will defend as "a work in progress", but when is that work due? Wayland has been in development for nearly 10 years now, and with each passing year it increasingly feels like this is a scam designed to bootstrap the Mutter shell. Face it: Sway works but it's hardly a DE, and KDE is functional on specific hardware and lacks several features. Wayland is a failure for everyone but the GNOME foundation, who I think intended this as a power-grab. In reality, we're left with an XKCD-worthy "two competing standards" situation.

People often cite a fractured desktop as the reason why Linux never takes off. Well, it's projects like Wayland that cause the worst fractures. We were promised a better Display Server, and what we got doesn't even compete with what we had in MacOS Sierra. I hate to be vitriolic towards software, but it's really pathetic.

My personal pet peeve with writing is exactly the contrary, I find the fact that people could read what I wrote very distressing. One of the best things that could happen with what I write is that no one reads it, because then I don't have to appease anyone or handle criticism. I'll admit it's a very cowardly stance to have, but it's very liberating in a sense. Obviously this means I'll start writing schizophrenic stuff eventually and need a reality check, it's okay though: "No great mind has ever existed without a touch of madness." - Aristotle.

Can’t help but laugh at the phrase “Real formal mathematics”. Mathematics are as formal as required to be understood by the audience. After all, math is just a way to communicate abstract arguments and reasoning. Computers require more help to understand abstract concepts, doesn’t mean that formulation is better than our current one. See Principia Mathematica on why too much formalism is not a good idea.

Most authors at some point write about their process. I've read many accomplished, experienced authors' takes. Authors seem to agree that there's a struggle at the beginning to figure out a process that works for them, and do in fact take the time to tell others what worked for them to help ease the discovery process for new writers.

Here's some examples of famous, accomplished and prolific writers doing what you claim they won't do:

Again, you are completely wrong and simply spouting vaccine conspiracy nonsense. It is very clear from the study that those "suspected but unconfirmed COVID-19 cases" are those who reported one flu-like symptom but had a NEGATIVE PCR test. A very detailed explanation of why you are wrong to want to include those in the efficacy percentage number can be found here: https://www.covid-datascience.com/post/refuting-peter-doshi-.... It is not clear whatsoever that the study was bullshit, and the results speak for themselves. An anecdote about your Prime Minister is meaningless and occurred AFTER this initial study period when the variants had changed the landscape and these numbers were no longer applicable.

> Cost of taxes just gets passed on to the consumer

> It's priced in.

That's just not true. It can only be true if you assume all sellers collude not to lower prices.

In a free market, one seller might eat the tax, undercut the rest, and net more money at a lower profit margin by attracting business from competitors. That risk generally prevents taxes from being fully priced in.

There's a few clever tricks that seem to make a pretty big difference with microkernels, but I know just enough to be dangerous.

I think one of the biggest ones I recall, and I think it was part of the L4 secret sauce, was the idea of throwing a number of small services into a single address space, so that a context switch requires resetting the read and write permissions, but not purging the lookup table, making context switches a couple times faster. With 64 bit addressing that gets easier, and allows other tricks. For instance recent concurrent garbage collectors in Java alias the same pages to 4(?) different addresses with different read/write permissions. Unfortunately this means your Java process can 'only' address 4 exabytes of memory instead of 16, but we will surely persevere, somehow. How that plays with Meltdown and Specter might put the kibosh on this though, and most processors don't actually support 64 bit addressing. Some only do 44, 48.

That's pretty old news though. The more interesting one to me is whether there's a flavor of io_uring that could serve as the basis for a new microkernel, allowing for 'chattier' interprocess relationships to be workable by amortizing the call overhead across multiple interactions.
I don’t have the time to google citable sources to refute false claims without any evidence in the first place. My sources are my own multiple very recent visits to Ukraine(last visit earlier this year), and my extended Ukrainian family and friends who were all taught either only Russian(older and grew up in Russian occupied territories or Eastern Ukraine) and at times spoke Ukrainian under threat of death. Or were taught both Russian and Ukrainian(younger, recent grads from the Kyiv region)

> Under no circumstances should CloudFlare or anyone else be running multiple isolates in the same OS process.

That depends on your scenario. In our case, all the JavaScript code is ours so we're not worried about it trying to exploit bugs and escape into native. Running multiple Isolates / Contexts gives us isolation on the JS side but also lots of sharing (the v8::Platform object and several other globals are shared in the process).

Of course, if you're running untrusted JavaScript code what you're saying makes sense (though I wouldn't go as far as Firecracker, low-rights sandbox processes a-la Chrome do the job).

Where is it saying that Physicists are trying to avoid anomalous data?

>"Oh hey this thing doesn't match what is expected according to the standard model but yeah the standard model is tots fine bro."

No one in the Physics community thinks like this. As I said it's very nearly the complete opposite, that if major problems in the model were found via experiment the person who found it would be cheering because they just guaranteed themselves a Nobel Prize. The problems with the Standard Model are widely known and deeply studied.

>So why is the standard model not in the trashcan?

Because despite it's known shortcomings it can still calculate 99.99% of scenarios with arbitrary accuracy. There's a reason Newtonian Mechanics are still taught, because for the cast majority of cases it completely works.

We are still experimenting with compute scaling, and the tech preview includes only a small fixed compute container. We have a custom proxy in front of a compute, and we can quickly change the underlying compute container with a bigger/smaller one. That works fine if you don't use per-session semantics and transactions are short-lived. But there are a lot of tradeoffs on what to do if there is a long-lived transaction or session-level object. So if we need to scale up the container in the presence of long transactions, we can:

1) roll back long transactions and enforce upscale

2) wait for a better moment to upscale (potentially forever)

3) try to do a live migration of running Postgres to another node (like VM live migrations, or CRIU-like process migration) and preserve long-running transaction

So far, we plan to start with some combination of 1+2 -- should be fine for web/OLTP kind of load. But ultimately, we want to arrive at 3), but that approach has way more technical risks.

There's something similar but it's in the .9-1.5 interest rate before 30% off of the interests when it's due. In Europe I think you can't buy bonds from another EU country but you can buy eurobonds (which seems to be different but are still emitted by EU countries).

> an active protection system specifically for top attack munitions like Javelin

Worth noting: The western-made MANPADs are designed to exploit a serious design flaw in Soviet-era tanks. The ammunition is stored in the turret where it is easy to ignite externally. That's why we have so much youtube of Russian tanks blowing their turret sky-high.

Long story short, design failure can't be remedied by anything they can put on the top of the tank unless it's another tank.
> but what you need here is an ISP that handles IPv6 prefixes properly

It's hard to get ISPs to do things properly in general; if it's for IPv6, it's even more difficult. I think the intent of IPv6 designers was for hosts to manage to be prefix fluid; you might set up ULAs for local traffic, and use whatever prefixes are advertised for non-local traffic. Of course, that's harder to do than to write an RFC about, so I can understand resorting to prefix translation to get things done in the way desired. Prefix translation has the potential to be stateless which is nice for resource management on the translation element, though.

It is a Debian derivative distribution with a stabilised subset of packages and a recent LTS kernel. Target images use non-GPL-3 software, which some industries require. It also comes with infrastructure for building images, atomic updates and so on.

I was wondering the same thing.

As you scale up with R2, D3, Email Workers etc, is it possible that the _future_ scale of touching very sensitive, "ought-to-be-secure / separate" data / code help reconsider this decision?

Without process isolation, all it takes is one bad Chromium commit or a incorrectly allow-listed JS/V8 command for this model to fall through regardless of how thorough the defense-in-depth/vetted Workers may be.

"the public clouds that run arbitrary native code in hardware VMs." -> Isn't it double whammy then that a V8 isolate + HW attack surface in combination could provide an order of magnitude more hackability?

"Last I heard there were still some lower-powered Android phones where the overhead was too high" -> I believe a Zygote-process fork was made available to Chromium at some point (https://chromium.googlesource.com/chromium/src/+/HEAD/docs/l... ?).

Have you played Cities: Skylines? There are definitely limitations to its fidelity, but every person and car is something you can click on and see their home, job, route. This gives much more realistic traffic for one thing (though there are mods that do an even better job).

Ultimately though, I doubt that high fidelity simulations are in the cards for consumer devices any time soon. Cities Skylines already bogs down on large cities.

> all economic theory and statistics that is controlling the biggest power decisions made with incredible wealth implications

Yes, I think so. For many reasons.

1. People tend to have pride in their work and can typically be relied on to follow their job description.

2. Someone would blow the whistle if the Fed was self-dealing.

3. A politician or auditor would have made plenty of hay if the Fed was self-dealing.

4. Running a central bank is incredibly difficult. Doing it while self-dealing, I imagine, is impossible. For evidence - Elvira Nabiulina is the central banker for one of history's worst Kleptocracy. Not only is she regarded as a clean-hands technocrat, she's also not really allowed to quit her job.

5. I need more evidence for a conspiracy theory than "imagine the numbers they deal with".
