Let me guess: you use XFS because of the large number of hardlinks it allows out of the box (as opposed to the small number allowed by ext4)?
What about people living in apartment buildings that can't charge at home?
It was news to me that in the Nimitz event ballistic missile defense radar was actually observing the UAVs in low Earth orbit days before the fighter jet encounter. Truly wild stuff. If I had to hazard a guess, these are unmanned (unaliened?) probes, the same ones that have been here for centuries or more. They may not even know or care what humans are or what we're up to. Maybe they keep dipping to the water to take algae samples or something similarly banal. And the reason they "run away" when the fighter jets get too close is just their onboard flight AI following a generic self-preservation script. However, none of this comports with the report of the fleeing tic-tac "appearing" directly at the fighters' pre-determined, secret CAP point.
I used btrfs on an EC2 instance with two local SSDs that were mirrored for a CI pipeline running Concourse. It would botch up every few months, and I got to automating setup so that it was easy to recreate. I never did find the actual source of the instance botch-up though. It was either the local PostgreSQL instance running on btrfs, btrfs, or the Concourse software. I pretty much ruled out the PostgreSQL being the originating source of the issue, but didn't get further than that. I don't know if anyone would suspect mdadm.

Other than whatever that instability was, I can say that the performance was exceptional and would use that setup again, with more investigation into causes of the instability.
> Canada locked down nursing homes completely yet 98.5% of COVID deaths were in nursing homes.

Isn't this explained by Canada's outstanding response to COVID that allowed it to have a much lower death rate than analogous countries such as the US?

https://www.bbc.com/news/world-us-canada-60380317

If your death rate is much lower because you succeed in protecting the bulk of the population, your death rate will be disproportionally comprised of the most vulnerable and at-risk groups.
> Intelligence is equally distributed between genders, but most professional physicists are men,

Why limit yourself to gender? Why not white vs other skin color? Why not the US vs another country? Why not democrat vs republicans? Why not western culture vs whatever other culture? Seriously, this kind of categorization is just ridiculous, especially when you speculate instead of showing evidence.

No, I won't be surprised if a STEM professor is reading topology. I will be surprised if a gender-study professor is reading topology. I will be also surprised if some stranger (i.e. I don't know the background of this person) who could only do pre-algebra in high school says Topology without Tears is the first book on Topology that they read and they immediately fall in love with topology. Possible, for sure. Surprising, of course. It's just a matter of probability.
Well,

I feel like one can easily get a bunch of "Really you should start with X" statements concerning math. Really you should start with proofs, really you should start with problems, really you should start with these concepts. I started with concepts rather than proofs or problem and I too went to a MA and various study. I tackled both proofs and problems but I don't think I'd have done as well if I'd jumped on these immediately.

So, altogether for someone wanting to get into advanced math, I'd say to look at the variety of advice out there and follow the kind that seems to help your progress.
Any writing "about the criticism he receives" is to deflect it. The state run channels are never critical of Putin because he controls the channels.

I think the idea behind this to make their computers as recyclable as possible. It was mentioned at least once in a product intro when discussing the machining process.

I also miss fun designs, but I think the choice to reduce plastic use is the “right” one.
Olive oil has the most research behind it, thus scientists feel most comfortable advocating for it; but that doesn't mean that something like canola/rapeseed oil isn't also similarly healthy for you, given its fatty acid ratios and polyphenol content.
I get where you're coming from. My first job out of Uni was in a start up, and I know I felt much the same as you describe here, with the added pressure of bug fixes being harder to distribute (since connectivity to the devices we worked on could be spotty).

The thing you have to do is just keep trying to improve your process. Beef up your test suite, set up automated regression testing, start reaching out to customers or combing through other forms of feedback. You can't stop bugs from creeping in, we're all human and it happens. It's totally fine! But you can put your best foot forward and give it your best shot.

You've got this bud.
Tripwire troops are also to make sure Russia knows that we will act.

The biggest disaster would be if Russia thought maybe the US would stay out of it, and then we didn't.

True: the differential at a point is a linear map; the integral is a linear form (on the vector space of functions).

Aerodynamics, usable cargo space, road width, existing parking infrastructure, safety in case of an accident, terrorism, ...
this is partial information.. the internals for the electrical grid were so solid, for so long.. then came the crack in the dam -- de-regulation.. while Happy Episcopalians in San Francisco planned their PC Green Energy sourcing, aggressive Texans built ENRON. Once there is so much money on the table, every day, the crack in the dam is hard to patch. Today there are now many fingers in the pie, and terrible incentives all the way down.

I have heard wise-guy finance say with a knowing look, that the "electrical infrastructure will be redesigned, and redesigned again." I believe them because, there is money to be made at each step. Repair of the forests and streams are the poverty work, not new electrical grid configurations, in California.

It is not the right time to throw the solid parts of the grid under the bus, and downplay the functional parts of the past, while pining for the workable future. A plea here (including present writer) to investigate and use fact-based analysis.
What do you mean? You can just go and buy a Toyota Mirai today, and you could in 2016. The hydrogen tank is 27 gallons in volume and weighs 193 lbs, for a range of 312 miles.

How big is a Model 3 battery pack again?
I love the ground-up design. However, i feel that in-place operations are missing from your rationale. Good algebraic calculators are typically able to 1/x or invert anything on the screen with one button without breaking the input flow, and repeat operations for the same left- or right-side operand by pressing =. This massively reduces the time spent on certain guesstimations when doing napkin math.
Going to renewables doesn't change the fact that the physical wires running across the state cannot move enough electricity fast enough to meet everyone's charging needs. It will take decades to upgrade all the wires in the state.

Generation isn't the problem it's moving it from where it's generated to where it is needed.

Mono-saturated doesn't make sense! Saturated means all the carbon atoms have as many hydrogen atoms as they can bear.

Mono-unsaturated is off by one. It's generally regarded as more healthy, and olive oil is generally strongly recommended over saturated fats.

Funnily enough, your body only knows how to synthesize saturated fats (palmitate), so your own natural fat is the "bad" one :)
I have been told a number of times I should give up on OnPrem because I could never afford to match the security of the cloud.....

The biggest drawback of hydrogen as well as gasoline is the fire / explosion risk. I'm curious how the hydrogen will be stored for transport as the fuel source.

For me, at least, there's an important difference missing from the debate over the term "C/C++": compiling C code is always much faster than you would expect, but compiling C++ code is always much slower than you would expect...
The AHA is completely and utterly full of shit and just like most major bodies pushing nutritional standards, peddles some fairly dangerous information:

https://www.health.harvard.edu/newsletter_article/no-need-to...

Seed-oils that wouldn't, largely, exist without industrial processes creating them as a byproduct (cottonseed oil, corn oil, soybean oil/Crisco, safflower oil, canola, etc.) are a HUGE driver of inflammation which is basically the root of every single disease - cardiac issues, cognition problems, neurological issues, autoimmune issues, cancer).

And there's a lot of theory supporting evidence they explain why people in the 80s - who ate roughly the same amount of calories and had the same level of activity as people today... were on average, a lot lighter in weight.

See: https://www.theatlantic.com/health/archive/2015/09/why-it-wa...

See: https://pubmed.ncbi.nlm.nih.gov/32008872/ and a whole ton more studies too: https://duckduckgo.com/?t=ffab&q=omega-6+insulin+resistance&...

We've been peddled industry lies since the 1950s, largely by coroporations who are founded by 7th Day Adventists ( who are vegetarian by faith and founded companies like Kellog), that Omega-6 PUFAs are healthy and it's the Saturated Fats (animal fats, largely) that are bad bad bad. Yet, since the 1950s ..our health keeps getting worse and worse while omega-6 consumption goes up and up and up..

These companies have influenced nutritional boards and peddle the Ancel Keys, Seven Nations Study ( https://en.wikipedia.org/wiki/Seven_Countries_Study ) as the basis for Saturated Fats being the main driver behind CVD. But the study intentionally left off nations that would have radically changed the results and thus the conclusion. 50+ years of nutritional health has been guided by this b.s.

Find me non-whole/fresh foods not jam packed with seed-oils. It's in marinades, tortilla shells, most bread, every body of packaged food you can imagine - chips, crackers, cookies, pre-made pies and cakes. Hell - i bought some salted pecans the other day from amazon and they were slathered in cottonseed oil for some reason. They're i n salad dressings, bbq sauces, wing sauces. It's even in dry-rubs for wings. Every. Thing.

Mark my words - when history has had it's say, seed-oil delivering a level of omega-6s that the human body was never meant to endure long term, will go down as causing more suffering than sugar ever did, but made infinitely worse by the level of sugar we eat as well.

The amount of omega6s we got from nuts or avocados or oats or whatever, was fine. Condensing it in the way we have and shoving it into everything has raised the titled the scale of consumption to toxic levels. And the AHA is Ok with this.

The AHA, IMHO, is an organization with zero credibility when it comes to understanding human beings and lipids. They're a captured front for industry who would pass off Omega-6s as "heart healthy" and muddy the waters of the debate with shit quality studies.
> cross-country trucks, trains, and maritime shipping hydrogen has greater potential.

On your list of things where hydrogen has potential, "trains" has got to surely be typo?
Even without renewables, there is enough generation and transmission capacity today. Cars charge at homes (overnight), offices (during the day), and other locations where they can dwell for hours at a time.

These circuits are the same size as a large heat pump or induction stove, and vehicle charging can be orchestrated in the same way Nest thermostats are used to shed HVAC loads in order to sidestep infrastructure constraints (“DER” or distributed energy resources).
Household energy usage has decreased a lot, especially with the push for more efficient household appliances, lighting and better insulation.

During this time some power-hungry industry has closed, and we shuttered basically all of our coal power plants.
It's not generation that's the problem, it's the wires that move the electricity from generation to where it's needed. It will take decades to upgrade all the wires to support electrification of all light vehicles.
My problem with this is that the costs of doing storage for 100% are a lot more hypothetical than the costs of doing 100% Nuclear. If something addresses that problem head on, fine. But most stuff seems to just do optomistic extrapolations from today's current storage experiments.
It will be safe, quick, clean, cheap and efficient. They just need 500bn to build the first part of the first one, 50 years to plan it, a huge liability cover and unlimited cleanup support.

> two types of social media strategies: open strategies, in which firms provided public responses to at least 75% of complaints, and closed strategies, in which at least 75% of the time, firms responded with just a single message directing the complainant to a private forum.

Consider a middle ground: direct the complainant to GitHub (or some other public off-Twitter channel). I wanna think this is the best strategy, but there's probably not enough companies doing this at scale to meaningfully compare.
The AHA is passing off horrible, unhealthy information.

Omega6s in high concentration are horrible for you and are inflammatory.
To support what you are saying, I found this article: https://wallstreetpit.com/89671-are-welfare-recipients-mostl...

> It's official: B-52 bombers are no longer authorized to carry nuclear gravity bombs," Kristensen said in a tweet earlier this week. "New Air Force instruction describes 'removal of B61-7 and B83-1 from B-52H approved weapons configuration.'

Also knowing the usual imperialist power games played there even if we would with huge cost stabilise the area, an other power coming in destabilizing it again is quite a big risk...
I never said it was commercially viable. All I said was that it makes sense for California to subsidize the technology to reach the state's emission goals until the electrical grid can be upgraded to support electrification of all vehicles.
In the short term yes. But that is exactly what the industry and employers rely on.

Long term, tipping just means these employers can compete for labor against other (non-tip) industries forced to pay higher, and without having to reflect that additional cost in their prices to the end customer.

The idea that the employer is the one getting the tip is a myth, and a well bolstered one for obvious reasons.

It's literally hearsay. Quite literally. Again, is there any treaty, any memorandum, any pact or anything about NATO not expanding eastwards? Any trade agreement, any signed piece of paper between heads of state and representatives of NATO or NATO members about this?

Because again, there is a 1994 Memorandum about Ukraine's borders and nuclear weapons which someone is deliberately ignoring.

I find it both troubling and disingenuous for people to beat the dead horse about the NATO expansion myth while completely ignoring Russia breaking both the 1994 Budapest Memorandum on Security Assurances and the 1987 Intermediate-range Nuclear Forces (INF) Treaty. Those weren't hearsay, they were actual agreements which were negotiated and signed.

But sure, 'you can't trust the west'. I'm coming from a former communist country and to be honest, the west never invaded. The Russians did, repeatedly. Across history, the Russians were the only constant invaders. And this is actually why my country joined NATO the first chance it got.

So, if someone is to blame for NATO expansion, it's actually Russia. Actually, this invasion we're witnessing is one of the best advertisements for NATO in history. So, fuck Putin, fuck Russia and their expansionist ambitions. I hope I live to see Putin's head on a pike.

One could also say "Subsidies for electric vehicles are clearly beating subsidies for hydrogen vehicles."

All the more reason to tax what you don't want and not subsidize specific solutions. The government should focus on the problem, not on specific solutions to the problem.

Because politically deciding what should succeed is not science. Politicians may not even be aware of a better solution. Or it may not be lobbied as hard as poorer solutions.

Hydrogen is unlikely to see widespread marine use due to engineering costs and safety risks. It's more likely that merchant ships will run on ammonia, biodiesel, methanol, or LNG.

It is pretty telling of the ecosystem when the major ways to get in rely on centralized actors that can and will lock you out when pressured.

Sure, "not your keys, not your coins", but what good is that when centralization is the reality of how most people interact with the technology.
Did you see 9000 pound Hummer EV with 3000 pounds of battery? Wonder what would be the weight of a hydrogen powered equivalent would be.
I might be misremembering, but I feel like when LCDs became mainstream, they were ostensibly worse in resolution than CRTs. CRTs were commonly at 1024x768 for a while, but I remember running specially-selected ones at 1600x1200 or even higher (1860xsomething?). LCDs replaced my nice high res CRTs with 1024x768, and then I waited a decade for 3840x2160, which was definitely a step up.

I remember being ridiculously excited by my circa-2004 24" LCD. How could a screen be that big? 1920x1200 pixels? How can there be so many!? And now that is like a tiny garbage dumb LCD that you find in the storage closet and decide isn't worth the desk space.

I actually really value the naming metric. I'd value a dev who looks at other classes to to see what the convention is rather than just adding their own personal form of camel-case. It shows a sense of collaboration.
No, the science is very very clear on that questions: it's absolutely in favor of poly-unsaturated fats. There is however a pocket of quacks and grifters on the internet concocting conspiracy theories about nutritional organizations/guidelines to sell books and whatnot.
Covariance and contravariance
Is that such a bad thing? I'm half-convinced that the “rank of a matrix” is just an artefact of a particular algorithm for inverting matrices. And distributions aren't everything; I can look up any distribution I want on Wikipedia, just as soon as I need it, but a proper foundation in what statistics means is much harder to come by. (I have enough of a foundation to know when it's being taught very wrong, but not enough to actually be very useful in day-to-day life.)
Same reason as it encouraged electric cars in the early days. To encourage competition to oil.
