I don’t understand why reversing a binary tree has become a favorite punching bag of the popular ire against programming interviews. It is an instance of the question: do you understand recursion from a discrete math perspective?

I’ve never been asked this question, so I haven’t “memorized” it as you say, but if you want to flip the order of all the nodes in a binary tree, you’ll need to at least reverse the left and right subtrees at some point. The understanding recursion part is knowing that reversing the subtrees is the same operation as reversing the main tree. In that way, it’s similar to the recursive solution to the Tower of Hanoi.
Maybe they're referring to the fact that if you do `for x in y` and y isn't properly annotated, then you will need to write

x: MyType

for x in y:
...

for x to be annotated properly.

If your threat model includes the threat of your government torturing you for information, then you don't need to worry about whether they are able to decrypt your data because they could just as easily plant some false evidence, or simply "disappear" you.

Specifically on the issue of plausible deniability, though, you probably don't want just a 1 GB blob of random-looking data, you want a file system with various levels of "secret compartments" which open up depending on which key you use to open it.

The game theory is that this prevents the attack you describe (and after which Assange named this countermeasure) because you could never prove to your torturers that you have given them the last key, and thus you would have no reason to comply.

It's worth mentioning that houses are not only worth far more, they are also physically much larger while household sizes have gotten smaller. In 1850 households had on average nearly 6 people; in 1890 five, in the 1930s four, in the seventies three - and today, the average household in America has two and a half people. Meanwhile house sizes have almost tripled since the 50s: new single-family homes were an average of 983 square feet in 1950 (about 280 sqft per person); today they are around 2,600 square feet (around 1050 sqft per person.)

That is to say - not only are the houses almost three times larger, but the average American has nearly -four- times more personal space today vs in the 1950s.

The improvements in cars have been crazy - I wrote a comment about that recently: https://news.ycombinator.com/item?id=26389885

Only 3.4% of jobs in America require very heavy strength according to the Bureau of Labor Statistics. With the US employment rate at 56.8%, that's 1.9% of the population that has to do a very strenuous job.

Compared to even very recent generations, we live in palaces, we drive in luxury, we work cushy jobs, and we have endless entertainment.

>All of it needs to be more evenly spread.

Absolutely. Among the world, of course, but even within America the inequality is still huge. The fact that we live with this inequality while having the resources to fix it is a stain on our collective conscience.

Encryption seems directly related to freedom of speech, freedom of thought, and privacy rights, in a way which gun ownership issues are not.

Encryption directly protects your freedom of thought by making it possible to communicate your thoughts to others without the government being aware of them, hence making it difficult for the government to punish you for sharing those thoughts if it disapproves of them.

Owning a gun doesn't directly protect your freedom of thought. Maybe you could argue that a gun can indirectly protect your freedom of thought, since if the government tries to restrict your freedom of thought, you can respond by violently overthrowing the government using your gun. However, in practice, that is very unlikely to work – an attempt to use your gun to violently overthrow the government is far more likely to result in your own death (or spending the rest of your life in prison) than in any actual change in the government or its behaviour. Even if you had a million fellow citizens with their own guns supporting you, you'd still struggle to win against the tanks, fighter jets, bombers, drones, missiles, etc, of a modern military.
In countries where assault rifles are banned, these things generally still are possible. With strict rules, for example you're only allowed to have your rifle and ammo at a shooting range, and psychological review of everyone involved.

Besides all that, it very much is a hobby for people. Much less a need than encryption, which is required to keep simple things like ordering something online secure.
Some personal rules for docs:

1. Explain, in plain non-jargon words (nobody cares how smart you are) what problem is being solved, how, and why.

2. Provide contextualized examples (no foobar), not making assumptions about what the reader knows or doesn't know (and avoiding condescending language like "it's easy," "it's common sense" or anything that suggests the reader is "dumb" if they don't get it).

3. Think in terms of a blog post/tutorial, not technical API docs as a starting point. This helps with adoption because people want to understand the thing first and then dig into API (just because you may not doesn't mean that others are the same).

4. Don't be lazy. Show respect for the people taking the time to use your stuff and put in the effort (grammar, structure, quality of examples, etc).

That's exactly the wrong take home; the only sane way to handle dns is systemd-resolved, as the article said. If you use your machine as anything resebling desktop/laptop, you should configure your network using Network Manager, especially if you have connections that come and go. Switching between Lan and wifi with dhcp is really low bar.

Anything else is just prolonging the agony that the linux networking configuration had to endure for years.

> Kurt Gödel, only a year beyond his PhD, announced a result which would forever change the foundations of mathematics. He formalized the liar paradox, "This statement is false" to prove roughly that for any effectively axiomatized consistent extension T of number theory (Peano arithmetic) there is a sentence σ which asserts its own unprovability in T.
John von Neumann, who was in the audience immediately understood the importance of Gödel's incompleteness theorem. [...]

> In the next few weeks von Neumann realized that by arithmetizing the proof of Gödel's first theorem, one could prove an even better one, that no such formal system T could prove its own consistency. A few weeks later he brought his proof to Gödel, who thanked him and informed him politely that he had already submitted the second incompleteness theorem for publication.

It is the nature of ambition not to be satiated. people making millions of dollars per year want to make billions. Billionaires strive to exceed their peers. Our leaders already have a lot to lose. Predictably most of our corruption isn't high risk blatant illegality its the boringly legal influence peddling where regular donations buy your "totally legitimate" interests and concerns additional consideration by decision makers instead of paying n dollars for a particular law.

There is no reason to believe paying them 2-3x as much so they can be really wealthy would lead to electing better leaders.

Our lawmakers make 175k directly in salary and aprox 1 million dollars for staff and 143k for office expenses. This is not including the cost of the lifetime pension they will qualify after only 5 years and lifetime health plan for themselves and spouse after 10 years in the house or 8 in the senate. Hint I know they pay I think 28% of the cost of their gold plan.

Lifetime a 2 term senator will cost the tax payers near 18 million dollars in total.
Yes it is a personal experience. I might change my opinion when / if VR headsets will look like a regular glasses so my fan can move the air properly.

As for towels - do you ride while periodically removing your headset and wiping your face? I can't imagine myself doing it. I have giant industrial fan that takes care of a perspiration and which is totally useless if most of my face is covered with that blob of VR set.

The two biggest "wow" reactions I ever heard at Google's company wide meetings were from the Keyhole/Google Earth demo right after they were acquired, and the first Google Maps demo with scrollable maps. IIRC the Keyhole demo started with the full planet view from space and then did a smooth continuous scroll into the Grand Canyon. Pretty mindblowing back in 2005 or thereabouts.
I've hosted email for myself and some other users for decades now. We all own our domains and aren't getting any younger. I'm a little terrified of the responsibility I've taken on and have no idea what I'll do when we start dropping like flies. Renewals will lapse, allowing squatters to snatch up our domains, read new incoming email and impersonate us. I'm not thrilled with depending on third parties, either, but now I wish it was someone else's problem who might outlive us and exercise a small degree of ethical oversight. Maybe there's a business idea here...

Denmark is a poor example since it is small, had too few cases and clearly is one of the farthest from herd immunity in Europe. Looking at the somewhere like the UK for what would happen, there were very measurable deaths in the <34 group that would occur if a country that did crisis management as (relatively) effectively Denmark opened without vaccination:

https://www.euromomo.eu/graphs-and-maps

So the 2 deaths would have to be averaged over additional years of lock down without an exit plan.

Sure, there is no reason not to prioritize mRNA for younger women if it is available, but these botched announcements will kill tens of thousands of young women world wide even if the production is never reduced and the delays in countries like South Africa are short lived.

I am deeply saddened by the behavior of the US and EU in this regard, it really amounts to a simultaneous false virtue signaling and through snubbing all but the best options, push other nations that don't have priority access to mRNA to now make deadly decisions for some kind of honor that doesn't even make sense.

Ryzen 5 5600x and Ryzen 7 5800x prices / stock have about equalized lately. So they are pretty easy to find at MSRP. You can currently get a Ryzen 7 5800x from many major retails for MSRP. The Ryzen 9 5900x and 5950x are harder to get.

It's GPUs that are nearly impossible to get right now. I've been trying for weeks to get one for a friend. I'm intently watching the stock notification Discords. There are frequent restocks, but they seem to sell out in seconds.

I think most people cannot ever understand these topics well, and from their perspective, it'll always be about cramming. -- It doesn't fit in their world view that others can solve these problems by thinking, not cramming, when they cannot?

Whilst to you, it's more about thinking, coming up with new things, but trying to learn it all by heart would seem a bit weird? -- And then maybe in a sense you're talking past each other?

Finally I don't think there is anything wrong with more farmlands in poor countries in South America. That's extremely hypocritical when the West did the same thing only a couple of hundred years ago and continues to do to this day, but oh if the poor South Americans learn how to farm on their own, the world will end.

If you don't have a PLB, the least you should be doing is telling someone close to you where you are going to be parking, how long you expect to be out, when you plan to return and what your expected route is. If any of that information changes then try to update your contact person before you commit to a different route.

I mentioned it because it seems the most socially acceptable and common example of this kind of behavior.

Now that I think of it, the "eat the steak then complain" tactic is probably the most common that's in this ballpark.

Personally, I do judge the people I've seen do this. They are self-centered and all did it for social reasons. If someone did it for a job interview I might understand, but invariably it was to have something they didn't want to pay for.
Possibly. Sometimes that gets stripped out when you try to send it. But yes, in theory it may have been in the photo's metadata too.

I agree that we should ideally minimize our agricultural footprint and turn everything else into a nature reserve. But we’ve got to work from the realities of where we are today.

Consider this image: https://www.bloomberg.com/graphics/2018-us-land-use/img/2018...

Notice that for the USA for example, not very much of the land is state or federal parks. The vast majority is used by humans in some way, and the reality is that they’re not about to turn it all into parks.

So, while pushing for the protection of as much land as possible, we should also study conservation on land that’s not already a protected area.

The book I mentioned has a number of examples where good conservation work has actually been done on such lands.
I don’t think there’s anything more important than being an outward-looking, striving species.

Once we get depressed and nihilistic and give up, the universe will be forever deprived of the colour and drama human civilization can add to all those bare rocks up there.

I had a phone system for a small office fail a few years back. We called a service company out and one of the first things he checked was a supercapacitor on one of the processing cards in the system that keeps some volatile memory stored through a power outage. Sure enough it had failed and in a few minutes he had it desoldered and replaced with a new supercap, he already had plenty on hand in the truck. I figured at the very least they would have swapped the card as a whole and maybe refurbish the failed one later on but due to the common failure of that supercapacitor they just always replaced it onsite. If that phone system had been designed to maintain that memory with a lithium primary battery instead it could have even been a user serviceable component.

If you look at certain languages, usage of such spaces is much more limited. For example, Elixir's docs are absolutely phenomenal, which leads to discussion being dominated by much harder problems than "how do I use X".

The article here covers the idea pretty well. You need to cover all 4 parts of documentation, and it should definitely be all available in official documentation, rather than relying on lower-discoverablity third parties.
