To make a fare comparison, you need to also compare the volumetric power densities (i.e. power delivered within a volume envelope vice just under a given mass threshold).

This is true for both energy and power densities - and it drives me bananas that these metrics aren't clearly specified for every single energy storage and conversion device.

Why does this matter? Because increasing a vehicle engine volume demands more supporting structure (frame), which generally drives up overall vehicle mass (hence cost of construction) and if the vehicle is operating in some fluid (air or water) the resistance to motion increases which drives up your installed energy and power for the same speed.

Imagine if you increase your car's mass pwr density by 2X, but doing so grows your engine compartment volume by 2X. Was that a wash? You can't tell until you eveluate the construction cost, energy storage and mpg impacts of having a larger car frame. Same is true with any vehicle.

Mass (specific) density is important, but volumetric density is too. Both need to be compared for a more thorough apples:apples comparison.
One assumption there is that testimony can provide you with justification. We are told by the article that Edmund Gettier has died earlier this year, and we seem to be justified in believing that. In that case, let's assume, justification and truth matches. But this isn't the case always. You may see that the color of the wall is red, for example, and may feel prima facie justified in believing that the wall is red. But it may be the case that, unknown to you, there is a red light projected over the wall, which is actually cream color. In an absolute sense, you are wrong, but your belief is still justified. 'Justified' and 'true' are used for different purposes.
How does the govt profit here? They are losing b/trillions due to covid in lost taxes, medical expenses, and individual sentiment. What is your solution if you don’t want people vaccinated? I couldn’t care less if people get vaccinated but I def don’t want to pay for them when there’s an easy way to lower those costs right now. (And, please tell me, who is “my” side? Logic and reason?)

Vaccines cut severity of disease and thus the societal burden of infection. While I agree these measures are potentially draconian it's wrong to say they convey no benefit.

>Except the documents that proved that the leadership of Solidarność, including Lech Wałęsa (Nobel peace prize winner, first post-communist president) were actually moles on regular secret informant payroll.

To be clear, documents show that he was secret informant in years 1970-1976, while he only became leader of Solidarność in 1980.
I also was a fan - and still am, can't wait to see the next test with Starship - but I'm getting sick of the vaporware around it.

Watch the debunking of Starship on the 'Common Sense Skeptic' channel on Youtube, they do a pretty decent job of explaining why most of the press releases are utter scheiss.

I am talking about them. As are plenty of others. Our collective moral choices are what underlies the law. So when most people talk about whether this is the "right" outcome it's not a technical question about the law as written, it's about that plus whether we have the right laws in the first place.
> This is the same reason why gasoline is ~15 times better than lithium ion, and typical gas car ranges are 400 miles but you can get a Model S with the same 400 miles range

I think the real reason is there is that no need for bigger gas tanks.

The most likely outcome would not be greater transparency or control over how such research is conducted. More likely it will move into the shadows, in military labs whose very existence is shrouded in secrecy. That's not just speculation, either. It already happened with biowarfare in the USSR and USA and probably elsewhere during most of my lifetime. Do people not remember these issues being discussed in the context of destroying the last smallpox samples? Or the anthrax scare(s)? Or the Reston "Hot Zone" incident(s)?

Rather tangential, however Ruby seems to exist entirely on the backs of Shopify now [1], and every Ruby-related post on here goes back to a Shopify employee. Did the founder of Shopify start with Ruby so now they’re wed to it culturally? Each of these Ruby posts has a gross mismatch between engagement and score.

I apologize for the digression, but Shopify today reminds me of some Delphi/object pascal shops I’d engaged with earlier in my career. Where the tooling became the primary focus and identity of the staff rather than the solutions (a sort of cargo culting off of that initial business success), and that focus meant the firm ended up being staffed with what could best be described as big fish in little ponds (e.g. the “Delphi expert” who was the guy who stuck with Delphi after everyone else had moved on to other technologies), in a recursive loop.

[1] - other successful companies started with Ruby / RoR (though in many cases it could be called legacy), but right now it seems that 100% of Ruby advocacy comes out of the halls of Shopify. The firm has turned to evangelism.

Yes, that's what Linux distribution, large companies and independent researchers do. I reviewed an amount of code myself. Also wrote sandboxes.
Because when IRC was popular servers and routes went down often and a single server couldn't handle all the users a network would have. Neither of those are a concern anymore.
Just because you find your culture tends to shady things does not mean that others do.

I worked at a service station in the early 90s, the owner was honest but going broke. We made $0.10/gallon on average, the sales of cigarettes, chips, and soda kept that station going. We had service bays but as more cars became proprietary and needed dealer service we had less service business. When the US invaded Iraq it really removed any profit that small station owners made from gas.

That station no longer exists, it was removed and in the space is now a small medical office.
I don’t understand how being Indian gives the OP any special insight on the business model of gas stations just because they’re also run by Indians.

As far as I’m aware neither is gas station business model knowledge hereditary nor is it taught in Indian school textbooks or part of Indian cultural learning.
We (Ireland) recently repealed a constitution amendment that banned abortion. My father is in his 90s and is a devout Catholic. He's exactly the type of person who would like to ban abortion, but before the referendum I had a long chat with him and have him a hypothetical situation: your daughter has just realised that she is pregnant. During the scan they also discover a tumor. The oncologist will not begin chemotherapy while she is pregnant. If she doesn't abort and begin chemotherapy her chances of survival are 10%. The embryo is just weeks old. Two major questions must be asked:

1. Is the life of a fully grown adult, who two children, a husband, parents, a brother, a sister and a large group of friends, worth "the same as" a 6 week old embryo that cannot actually think or feel?

2. Multiple choice questions: who should get to say whether or not she is allowed to abort in order to have a chance at survival? A judge? A doctor? A priest? Her father? Or.... Call me crazy... But maybe her?

And that last question is the very definition of "pro-choice"

Thanks for providing that insight. It sounds like a platform issue.

I’ve often been curious about the animus towards Teams because I’ve always used Teams on Windows and the experience has been pretty good. I’ve been very productive with it, especially the last little while when I had to use it to coordinate a large distributed team. I haven’t experienced any of the above issues on Windows. In fact on Windows the video codecs and video networks are so good that they rival or exceed Zoom’s in many cases. As well, we have the large enterprise license too (most of us are in E3 or E5 tiers) —- I’m not sure if it makes a difference in terms of QoS but many of the complaints I’ve come across from small business or free users I simply don’t experience on an enterprise Teams license.

I think the biggest issue is that on non Windows platforms, Microsoft does not pay enough attention to make sure there is feature or reliability parity.

I realized this recently switching to macOS. Outlook on the Mac is crippled and simple things that I relied upon on the Windows client simply don’t exist on the Mac client. Even simple features like showing a calendar panel or being able to define more complex mail rules are missing.

For Teams, the code base is ostensibly the same since it’s an Electron app but it sounds like Microsoft’s QA efforts on the Mac are not on par with its efforts in the Windows side.

I say this because if Microsoft wants to, it can do better. Visual Studio Code for instance is excellent on all platforms and keeps getting better. My main desktop is a Linux machine and i’ve switched from trusty gVim which I’ve customized for 20 years to VS Code for dev work because it’s that good.
As a web developer I can only agree with all that you said. It's like some companies are actively trying to make visitors leave their websites and never come back. Or at least avoid them as much as possible.
Yes, morally I agree. I think we've ended up with an absurd outcome. That's a sign to me that there's a mistake somewhere upstream.
I could be reading it wrong, but based on this:

I think so. I'm totally not familiar with the pros and cons of mounted drives but I assume there are some operations that are possible or easier to do when it's a mounted virtual drive vs a plain folder? Something related to file streaming where you need to detect that a file is accessed on the fly and "stream" it if it's not already available on local disk?
This is why I now refuse to use google products. The constant XYZ is deprecated now use this new thing that doesn’t fully work is tiring.

Apparently it saves what you do to the address bar. Which is good on its own, but messes up history when you use href.assign() instead of .replace().

What's interesting is that the HSL/HSV wheel in Adobe programs has a slightly different disribution compared to the rest of the industry, they've basically tweaked it perceptually. This yields different results in their color grading tools within camera raw and premiere.
Yes. You don't see it often, but drives can be mounted per user session instead of at the system level.

The easiest way to see this is to use subst to map a drive and then try to navigate to that drive from a UAC-elevated command line. (You won't see the drive since it exists in a different session.)

Mapped network drives and drives shared over remote desktop are other examples of per-user mounts.
What a propaganda piece. “many say”, etc.

Stop spreading lies like the lower COVID mortality compared to flu. It’s disgusting.

Stop lying about what the article says, it’s not about the national recommendation of a country (that famously botched their response).

“Nearly zero” means nothing for societal outcome, certainly for mortality. What is the number of people infected, “nearly zero” of which die? Then these numbers become meaningful.
How many companies seriously start revoking visa sponsorship the moment an employee pushes back on a Jira ticket?

Really the issue is being fired over it isn't it? The visa just makes being fired worse for employees requiring one.

I would hate to work at a company where a bit of debate on 'is this really a good idea' were a firable offence; sounds like the 'believe it or not - jail' scene from Parks & Recreation! That's satirising a visiting delegation from a developing country under military rule.
See my comment to answer this question. Volumetric power density impacts are neglected in the OP's 'back of the napkin' estimate comparison. As you suspect, you need to account for the motor size and the specific application to see if this motor is a benefit to you.

Complicating matters is the fact that the OEM does a poor job of presenting these metrics up front on the landing page.

The people saying to keep your day job and work at a creative field on the side are probably right. As long as that day job is a low-stress 40 hours a week. Working at a high stress high overtime job will make creative work on the side impossible.

I spent the better part of a decade trying to make it as a screenwriter. During that time I worked what was basically part time dev work. Finding those situations was a little tricky, but the income was comfortable and the time demands low.

Despite having scripts that got me meetings with nearly everyone I wanted, nothing ever moved forward and eventually I moved on. I know I sacrificed some income over that time period, but I'm glad I got to play the game for a while.

Now I'm still working part time, fully remote, but self-publishing novels that sell a few copies. That satisfies my creative needs if not my ego needs.

If you want to write, start now. There's no point in waiting. But it'll be easier on you if you keep a decent income while doing it.
It's a good question, but we must consider downstream effects. When one buys SP500, it pushes up the price in price/earnings for those companies, making them slightly less attractive investments and therefore other small companies slightly better investments. When, residually, some of that money flows to increasing the price of a struggling $1b company (efficient market hypothesis), they're now able to be capitalized better in investing in a second factory, or affording their debt as to not go bankrupt and have further knock-on economic effects.

Except this is absolutely wrong but sure.

The idea that the IRS (actually state tax agencies since a lot of gas and sales taxes go to states) don’t know about and aggressively target small businesses is fiction.

In fact, the likes of small gas stations falls squarely in the tax evasion targeting sweet spot because they are large enough to draw enough money from in a tax evasion case, but not large enough that they will use up government resources in never ending lawsuits.
This has been true for decades. When my dad ran a gas station, the profit came from selling goods like food and cigarettes, or repair services. But he stopped selling cigarettes in the early 1990s when my mom, a nurse, thought it was not right to be selling poison. My dad had a few angry customers, who asked him, "What kind of gas station doesn't sell cigarettes?"

I was so fascinated by the business and life lessons he taught me. There are unscrupulous ways to make money, but fortunately these are not done by the majority. A gas station dealer has to buy gas from the company at a set price. Often times, there is a "black market" of gas, sometimes mislabeled, sometimes stolen, that is offered to dealers by unscrupulous people. You can buy this gas for cheaper and make more money on the margin. If the company catches you - and they have every incentive to catch you since you are not buying from them and selling an inferior product with their brand - you are in trouble.
"25%" + "5-10%" = "30-35%".
Yes, there are differences that seem unlikely to arise as part of natural evolution. There are also differences that seem unlikely to arise as part of a lab experiment (i.e. things that are well beyond our known or predictable ability). Some kind of unlikely event still managed to happen. Treating the statistical improbability as evidence for only one conclusion is suspect.
ICU load is now much lower for a given level of cases and barring new variants it will likely decrease further with boaster shots and more people recovered from infection and possible new therapeutics. Moderately increasing ICU capacity would be expensive but not vastly so. See "people in ventilator beds" in the link

I love this work - the OKLab model is really wonderful.

But I think for color pickers, there are cases where "constant lightness" is not the most important constraint. For instance, you might really mean "the most saturated primary in each hue" and then - you may want the most saturated colors to appear on a line (saturated red, saturated blue, etc.). A constant lightness constraint makes these appear in a really unpredictable pattern.

In less saturated colors, this constraint is very useful and feels right, but I think at the extremes it may reduce usability.
The Docker homepage (https://www.docker.com/) is even worse. It takes minutes in my case when I press on "Essential Cookies only". And this is reproducible. It's like this for more than a year now.
> You are never looking for the whole schema all at once.

Well we have to. Our system exports the data to other systems, which would involve generating a file with all the data (think order or invoice but with 100+ fields). For many of our customers this job is time sensitive.

Besides that we have overview grids (think "all active orders") for our customers, for many of these our customer will want to have 20+ fields visible. Using your method that can be 50-100 joins, and this would be an interactive case so again time sensitive.

That's why I was curious how it scaled.

> No one ever said it had to be running on disk either.

Well our data absolutely has to be persisted to disk on commit, and a stale cache is not tolerable. But apart from that, sure.

I don't understand. "equal" and "less than" are disjoint. "subset" and "equals" are not disjoint (equal sets are each others subsets), so that's a whole different example.
Especially for a long range teslas. 300-400 mile range plus 250kW charging is pretty close to the gas vehicle experience. It’s doable to do exclusively supercharging, although you’re missing out on some of the biggest benefits of EVs.
> vaccines do not stop people from getting infected and infecting others. ... does not mean the people inside can’t get infected so this measure does not help achieve that goal.

This is absolutist thinking - "people can still get infected, so this does not help at all" - this not true in the slightest:

"it can still happen" is not the same "as it happens at the same rate as before". And "It's not perfect" isn't the same as "does not help".

vaccination reduces the rate of infection, a lot, so it does help, a lot. None of this is binary, thinking in absolutes will lead you to false conclusions.

> The reason gas stations run aggressively on cash is because they're running two different sets of books a majority of the time.

I do not know about this. Every single gas station that is cash-only, they also allow debit cards which you cannot be used for tax evasion. The main reason is station owner doesn't want to pay processing fees for credit card transactions since margins are so thin.

But if they have a store they will enable CC, Apple Pay, Android Pay, and all other things. This is where the money is. This is my anecdotal experience (from talking with an owner) and this article confirms that.

I just joined a new software team. I had a time where I felt like I couldn't really get a point across to a teammate. Not that he didn't agree, but I just didn't feel understood. Then it happened with someone else. Well, after the seventh time with the fourth person over the third medium, the common denominator became obvious (me).

I think part of the problem is my whole team is honest and direct. They really engage with ideas. Sometimes they'll engage with an idea different than the one I intended to communicate. Because they're really taking the idea on, the misunderstanding will stand out.

Maybe most people don't do that as often. They just nod along and passively agree. Only when it comes to the final decision/action will they fully engage. And if they disagree with that, they'll let you know (maybe) even if they've been uh-huh-ing every supporting argument on the way.
