> I’ve heard it said that stealth is a lie.

The pop culture version of stealth providing perfect invisibility was always a lie.

But it does provide decreased detection range. If your radar detects a traditional plane at 300 nm but a stealth plane at 30 nm, you're effectively blind as a bat.

> That radar technology from World War 2 era is able to detect stealth aircraft. The Russians just built up more of that kind of radar band to detect current stealth planes.

> This is how the F-117 got shot down in Yugoslavia. It was supposed to have the radar cross section of a small bird.

Stealth technology apparently isn't that good for old school low frequency radars, so yes, there's a grain of truth there. But such radars provide poor resolution (which is why modern radars tend to use higher frequencies) so they are not that useful for targeting. That F-117 case was AFAIU a combination of poor operational planning (flying the same routes over and over again), as well as a 'lucky' shot.

There's of course a lot of research into 'stealth-defeating' technologies. IR guided missiles, multistatic radar etc.
I think interest rates almost can't possibly explain it.

The cost to take 4 single family lots and build a 12 story building to fit maybe 100 units.

The actual per unit construction cost is like $100k ($10M for the building), but that is because they are all custom.

Mass producing housing would easily drop prices 50%.

Let's say these 4 lots with houses on them are worth $1M each.

In the mass produced housing model, the price per unit including land is $140k.

This is ballpark a 10x difference. Why is the spread so high? It's not interest rates.

Best solution for potatoes is to put plastic tote or wooden box in the garage or basement, fill halfway with sand and put the potatoes in, covered lightly with sand. Keep a lid on top. If that’s too much, use a paper bag and put it somewhere cool that won’t freeze.

My family does this every winter — I buy 100 lbs of potatoes from a farm for $15-25.

It works for carrots too.
Annie's is owned by General Mills. I wouldn't be surprised it if went away around the time of the acquisition. You could try asking them for it. :-)
I worked at a niche health food grocery store many years ago that got a fair share of weird customers. The store introduced checkout scanners while I was there; previously the employee at the register would simply type in the price of each item. Most customers didn't care but a very vocal minority was outraged about how toxic and dangerous the little scanner lights were.

> All food is healthy if you eat it in reasonable amounts

That is true if one is speaking about the basic categories like "fats/carbs/sugars" etc., but the concern is really about certain additives in processed foods. When ingesting a carcinogen, sure it is repeated exposure that raises one’s odds of developing cancer, but all it might really take is just a single time. That is why additives are sometimes banned from country to country: because there might not even be a "reasonable amount" greater than zero.

From Tate et al 2009:

Better yet, because optimizations are allowed to freely interact during equality saturation, without any consideration for ordering, our approach can discover intricate optimization opportunities that compiler writers may not have anticipated, and hence would not have implemented in a general purpose compiler.

Many years of being on the receiving end of issues shows that there are a large number of different potential problems which manifest themselves in similar ways. Some are fixed, some persist, some may be new. If people don’t file issues describing exactly what they tried and what happened, this vague complaint just goes into the bucket of “Who knows? Hopefully someone else files a proper bug report.”

I’m not sure what issue you think you identified by googling such a short problem description, but it seems like it could be any of:

- slow internet connection

- firewall / proxy issues

- antivirus gumming things up

- file system being slow when dealing with lots of small files (Windows mostly)

- precompiling Plots took longer than expected

- precompiling Plots hit a deadlock

- loading Plots took longer than expected

- loading Plots hit a deadlock

- something else?

Worse, what “stuck” means is also ambiguous. Does that mean it failed with an error? Does that mean a download started but then was too slow for the user’s taste? Does it mean that a download started but never got any data at all? How long did the user wait?

My best guess is that git cloning the registry on Windows is taking a long time and isn’t actually stuck. There’s a fix for that being worked on for 1.7 (don’t unpack registries).

Upper management cannot focus and project their insecurities on employees.

Upper management policy to hire the cheapest employees backfire as these employees typically less productive, unwilling to learn and doing absolute minimum.

To compensate for that - management invent policies and procedures to defocus attention from their own inability to lead and inspire.
My understanding is that land value tax would actually increase the taxes paid by existing residents as more people move in.

For example, if a town has 1000 families split among 1000 equal parcels of land, each landowner would contribute enough taxes to the city budget to provide services for 1 family. If I then take 100 parcels of land away and put 600 apartments on them, now I have 1500 families among 1000 parcels of land. The city will now require each landowner to cover the budget costs of 1.5 families
When a random addict dies everyone knows whose fault it is. But when a rich addict dies, everyone wants to know whose fault it is. Sure.
Yeah, the Google flights issue is difficult. On one hand, the business practice is problematic. On the other hand, Google flights is so much better than its competitors it's ridiculous.

If there was a way to split Google flights into a separate company and somehow ensure it wouldn't devolve into absolute trash like its competitors, that would be a good thing.
Yeah... now their ingredients are (from their web site):

Organic Pasta (Organic Wheat Flour), Whey, Cultured Cream, Nonfat Milk, Salt, Butter (Pasteurized Cream, Salt), Dried Cheddar Cheese (Cultured Pasteurized Milk, Salt, Non-Animal Enzymes), Corn Starch, Citric Acid, Annatto Extract (For Color), Lactic Acid, Sunflower Lecithin, Sodium Phosphate, Silicon Dioxide (For Anticaking).

None of this bothers me, but the declaration "No artificial flavors, synthetic colors, or synthetic preservatives" seems out of place with those last six ingredients. It's technically true, but that's a context where you sorta want more than merely "technically true".

I don't think any of them are harmful... but then, neither are the artificial and synthetic versions they're replacing. They don't strike me as all that different from the Kraft ones:

enriched macaroni (wheat flour, durum flour, niacin, ferrous sulfate [iron], thiamin mononitrate [vitamin b1], riboflavin [vitamin b2], folic acid); cheese sauce mix (whey, milkfat, milk protein concentrate, salt, sodium triphosphate, contains less than 2% of citric acid, lactic acid, sodium phosphate, calcium phosphate, with paprika, turmeric, and annatto added for color, enzymes, cheese culture).
I found it quite odd how the consensus was quickly reached early on about the food market. Really not much evidence was presented outside of it is quite possible for a coronavirus to go from bat to human.

It’s also plausible that at a bio research lab that studies coronaviruses a leak occurred.

Two things:

1. There are longterm kernel releases, with up to 10 years support, and Android uses those exactly to avoid major support issues (https://en.wikipedia.org/wiki/Android_(operating_system)#Lin...).

2. That doesn't fix the issue that Qualcomm themselves do not want to release documentation and only want to support their hardware for up to two years. Ergo, you would run some outdated binary blob.
I did not say it is rational, but you simply cannot ignore its existence in hopes it goes away.

Felix Bloch reports an enlightening conversation with Heisenberg [11]:

“We were on a walk and somehow began to talk about space. I had just read Weyl’s book Space, Time and Matter, and under its influence was proud to declare that space was simply the field of linear operations.

‘Nonsense,’ said Heisenberg, ‘space is blue and birds fly through it.’

This may sound naive, but I knew him well enough by that time to fully understand the rebuke. What he meant was that it was dangerous for a physicist to describe Nature in terms of idealised abstractions too far removed from the evidence of actual observation. In fact, it was just by avoiding this danger in the previous description of atomic phenomena that he was able to arrive at his great creation of quantum mechanics. In celebrating the fiftieth anniversary of this achievement, we are vastly indebted to the men who brought it about: not only for having provided us with a most powerful tool but also, and even more significant, for a deeper insight into our conception of reality.”

What is thus this “deeper insight into our conception of reality”, that allowed Heisenberg to find the equations of quantum mechanics, and that has no major use of the quantum state ψ?

Laughing at people who are trying to be mean to you can be a more practical and healthy reaction than internalizing and mirroring their meanness.

Not saying that this is true in your case but I have seen this too often that managers think they can code just because they did it 10 years ago. It's surprisingly hard to write good code when you are not in practice.

> (1) regular taxis could not be summoned via an app or web page, instead requiring a phone call or curbside hailing

This is partially true. It wasn't just that taxis couldn't be summoned through an app. It was that when you tried to summon one, there was at best even odds of one showing up within 30 minutes. Drivers could and did take curbside hails as they saw fit, and a dispatch often seemed to amount to no more than a polite request.

I've used taxis apps in the years since Uber's debut. Replacing a phonecall that gets ignored with an app's request that gets ignored is not an improvement.

> (2) their credit card terminals were often broken so that you had to pay cash.

They essentially never were. Cabbies just prefer cash. The real issue here is that cabbies had no compunction about lying through their teeth and there were no consequences for this. The whole system was set up so that there was in-theory accountability but no in-reality accountability. Uber took this away entirely by forcing payment to be handled entirely via the app.

> That should be good enough to make them a viable alternative to Uber/Lyft for probably 95% or more of the rides in a US city.

With the above points in mind, things take on a slightly different character. Using Square accomplishes nothing except giving cabbies a slightly different thing to lie about. Without the assurance that your driver won't make random other stops or otherwise not show in a reasonable timeframe, the request app isn't that useful.
Can confirm. I know many people who live in New England houses ~150 years old.

That's actually quite reasonable since the council tax finances local services (hence the name). The person who benefits from local services is the occupier, who may or may not be the owner.

The issue with council tax is that it is extremely regressive: there are 8 bands with (very approximately) only a factor 4, from £1000 to £4000 a year, from lowest to highest. This means that a person in a crappy studio flat on a council estate pays £1000 and another person in a Buckingham Palace style mansion worth tens of millions with tennis, swimming pool, whatnot, pays no more than £4000 since that's the maximum.

This may explain why the wealthy in the UK never complain about council tax and tend to oppose land value tax...
(Controversial?) opinion: patents encourage innovation because they force competitors to find new solutions instead of only copying existing solutions.

That doesn’t mean that it could not go terribly wrong as for example when patents blocked progress in 3D printing for decades.
Not the original poster, but I also work in the grocery services industry with a startup that does door-to-door grocery delivery.

My guess is this person meant relationships with the farmers and producers being critical. At least this is true for us.

If you want to go mass market instead, then there are only a few wholesalers to choose from.

I disagree. Writing is helpful for thinking things through, but the writing itself doesn’t do anything. I used to take a lot of notes to remember things and it can just act as an excuse to not think hard. It’s the hard thought and periodic review that cements things

This is precisely why this story does not matter. The director of the CDC fulfills a political duty and they serve at the whim of political figures. We rely on scientists because they provide evidence, and without evidence, scientists are dreamers -- or paid propagandists, or unpaid nationalists, who knows! It's irresponsible to keep spreading this type of disinformation and to continue fueling growing divisions in the U.S.

Invisibility and the Dragon
A teacher of mine once told us that "The road to hell is paved with good intentions." I think that's one of the paradoxes of life and we see this over and over again where a lot of good people try to do the right thing but the collective effects of their efforts end up being net negative. Rather than conspiracies, I think this paradox can explain some of the challenges we face today. Barbara Tuchman wrote a great book called "The March of Folly" that basically documents some famous cases of people unwittingly working against their own best interest, even if the individual steps themselves might have made sense.

The article explains this.

To summarize: the "codepoint" is a broken metric for what a grapheme "is" in basically any context. Edge cases would be truncating with a guarantee of a valid encoding on the substring? But really you want to truncate at extended grapheme cluster boundaries. Truncating a country flag between two of the regional indicator symbols might not throw errors in your code, but no user is going to consider that a valid string. The same is true of all manner of composed characters, and there are a lot of them.

So the only advantage of using the very-often-longer UTF-16 encoding is that it's an attractive nuisance! This makes it easier to write code which will do the wrong thing, constantly, but at a low enough rate that developers will put off fixing it.

Unicode is variable width, and what width you need is application-specific. That's the whole point of the article! UTF-8 doesn't try to hide any of this from you.
I’ve also run into plenty of quirks or bugs in Chrome. That’s not a reason to give up on a browser unless the vendor gives up on it – and it’s especially important to see how many proposals started on Chrome but were substantially improved by working with other browser implementors. The Chrome team are quite good but they’re not perfect and the web benefits from multiple perspectives.

- automatically integrated with Let's Encrypt for custom domains
- deploy previews!!!

And so much more.

The F-35 makes me wonder if US military superiority is as great as it appears on paper.

For example our military budget is 10 times that of russia. However does 1$ russia spends vs 1$ the US spends on equipment equate?

Think it may be very likely that Russia (and China) are getting more bang for their buck and the gap between forces isn’t quite as extreme.

No question the US has the most powerful military in the world and it’s Navy presence is unmatched. However moving forward is this sustainable ? Russia and China catching up?
This is not a big deal as you make it sound. Insurance is like 1k per year these days on a $300k house. If it was $500 five years ago, this $500 increase is nowhere near as substantial as the interest rate change relationship described above.
Agree with array/list, we don't need more contiguous chunks of memory, but tuples are very different, if only because they allow elements of different types. They're really more ad-hoc unnamed structs than collections.
