I used to enjoy Quora, but it lost its charm and I quit once my feed became mostly filled with questions such as:

- As a software engineer, what makes you roll your eyes every time you hear it?

- What did your mother say that made your jaw drop?

- What can I learn in one minute that will be useful for the rest of my life?

Those open questions just feel clickbait-y, with no real value added.

I occasionally see questions similar to the last one on HN (for example: https://news.ycombinator.com/item?id=21913129), it’s OK once in a while, but I hope it doesn’t become the norm. I think the HN userbase’s mindset and strong moderation guarantees that for now.
I think the more likely scenario is that they’re filled with typos to avoid spam detection filters for keywords and phrases. The gullibility theory doesn’t explain the advantage of using similarly appearing letters (the number one for the lowercase L), etc., which spam uses all the time.
I've been using Hammerspoon for years, and have been incredibly happy with it. It is still actively maintained, has a large userbase, and has a lot of pre-built solutions for things. Importantly, it's not just for window management. You can do a lot of powerful things with it.
I used to do a variation of that in Armada 2525. Neutron stars always had very bad planets. I would put a colony there, drop enough work units to build a self destruct, then blow the planet. Artificial planet, now I had a good planet around the neutron star--and every ship built around a neutron star had double defenses. Once I had one such world I used it for as much of my shipbuilding as possible as the ships would almost never be destroyed. I would then go for the other neutron stars, both to increase my building ability and to keep the AI from building such ships. Once I had them all the game was won.
Pandas has enough gotchas that it looks friendly until you hit one of them. Examples of gotchas:

Want to join two dataframes together like you'd join two database tables? df.join(other=df2, on='some_column') does the wrong thing, silently, what you really wanted was df.merge(right=df2, on='some_column')

Got a list of integers that you want to put into a dataframe? pd.DataFrame({'foo': [1,2,3]}) will do what you want. What if they're optional? pd.DataFrame({'foo': [1,2,3,None]}) will silently change your integers to floating point values. Enjoy debugging your joins (sorry, merges) with large integer values.

Want to check if a dataframe is empty? Unlike lists or dicts, trying to turn a dataframe into a truth value will throw ValueError.

> We never get a clear answer for why the Civic Center Engineers got the inputs wrong, so we can't conclude that it was because of their expertise.

I think that's because you're focusing on a component, and not the whole. The construction project had a problem, and part of that is because they trusted the expertise of designers. Various people in charge of aspects of the project should have pushed back harder, noting that the expertise they were relying on was obviously false, since it didn't match reality. The problem is not the computers, but the designers, and the expertise in question is that of "trust your designers". The story and moral plays out the same whether it's a computer, or some bad math, or even purposeful sabotage.

Funnily enough, it might be possible to attribute your focus on the engineers as an aspect of priming itself. Even if you aren't an engineer or in a related discipline, this forum is very heavily frequented by such people and often focuses on such issues. As such, focusing so much on the engineers themselves and what they did or didn't do to the point if missing the whole can be expected. Well, it can be expected if you accept that priming plays a role, at least to some degree.
Interesting enough it’s possible to explain to the people that you want to be left alone when e.g. you have your laptop lid open. If done politely but firmly they take it easy and respect your space. I only point it out because it seems once the ice is broken there’s no way to keep that distance but it isn’t so.

I would love to see Seattle kick more money into getting Ballard <> Downtown done sooner than 2035, that is a perfectly valid complaint.

This is only the symptom of the real problem, which is way too high cost of building. Light rail construction costs are planned to be around ~$500M/mile. In comparison, whole subway line in my home town of Warsaw, finished in 2014, built 6 miles of underground subway for ~$200M/mile. Considering that subway typically costs 5-8 times more than light rail per mile, $500M/mile is simply insane.

The cost, and not construction schedule, is the real problem. The construction schedule is so slow precisely because money is scarce. If we could build light rail for $50M/mile instead of $500M/mile, the project would make way more sense, and would also most likely be more than halfway done by now. On the other hand, since the money is scarce, not only we know that we won't get the project finished by 2035, but it also means that won't get anything more than ST3 by 2035.

I think transit _options_ are an extremely important quality of life item that creates a more dynamic and healthier city. They're just that though - options. I own a car, and I use it for trips that don't make sense to do any other way (e.g. going Skiing). That doesn't mean I want a world where nobody drives, but a world where people have multiple choices for personal mobility.

I agree. At the same time, I'd like everyone to internalize the cost of the options they choose. That means charging the costs of transit to transit users, and at the same time, charging drivers for congestion they cause.
To build on what yogthos writes here, Paredit was an absolute game changer for me. The ability to edit your code as a tree structure rather than just a sequence of characters lets you do many kinds of edits far faster than is possible in non-parentheses-laden languages.

The following are all a single key combination in most editors that support Paredit or equivalents:

- Kill an entire loop or data structure to the right of the cursor

- Swap two deeply nested expressions to the left and right of the cursor

- Absorb ("slurp") or expel ("barf") expressions to either side of your current expression, into that expression

- Delete the entirety of the expression enclosing where your cursor is, leaving everything to the right intact but raised to the enclosing level (this one is amazingly common but you would never think to use it until someone shows it to you, after which you use it every day)

It takes a couple of days to get these and many other shortcuts into your fingers, after which it's hard to live without them. http://emacsrocks.com/e14.html is a good introduction.

Structural editing is the first thing I miss going back to Python, Ruby, JavaScript, etc. That, and, of course, instant REPL evaluation of the expression under my cursor.
In a similar spirit, I was reading a few months back how we are ruining today's children's imagination by keeping them busy every waking moment. The problem (psychologists discussed) was that kids need to be bored, and once they get bored they start day dreaming (https://www.parent.com/5-surprising-benefits-of-letting-your...)

I started my journey to minimalism a year ago, that gave me time to get "bored", be and feel less busy, meditate more, focus more, and I could find new aspects of myself; boredom helped.

Yes, holes exist and are a useful formalism. But you are wrong, holes very much behave like other elementary particles (pseudo-particles), and you get to call these things particles, exactly because they behave like excitations of a field.

If you insist, sure, you can make up an infon and call it a particle. However, it would not behave like anything a physicist would call a particle, nor would it use any of the mathematical tools that were developed to deal with particles, nor it would provide any useful intuition or insight, nor would it provide any pedagogical value. And at that point why bother calling it a particle if it does not behave like one.

Most toothpaste has about 1000 ppm of fluoride (0.1%), which isn't a "high level" - in fact, it means that one blob of it on a toothbrush has about the same fluoride content as a large glass of fluoridated water.

"High level" in this case comes in with fluoride rinses or specialty toothpaste, which can have 5000+ or 10000+ ppm of flouride.

The 10 year ceasefires are because Paradox likes to make it impossible to take out an enemy in a single war. Each war can only take a bite of a certain size, then you have to wait a while (during which they can rebuild their military) before you take another bite.

In theory it means a loss isn't catastrophic, but in practice if they can beat you once they can beat you again, your only real hope is to find allies--and when you're weak it's unlikely you'll find allies.
I mean, whenever I have this problem, I fall back on my (terrible) SPSS habits and just recode NaN to -999. With integer datasets that mostly works fine. You could come up with some alternative solution, too.

Personally, I'm an amateur at best, but Pandas has made it possible for me to do some really handy things.

Personal favorite feature: multindexing on rows AND Columns. Multiindex is such a common pattern, and so poorly handled in things like excel. Pandas really saves a lot of time with re-indexing, pivoting, stacking, or transposing data with multi indexes.

Huh? The Catholic Church is the #1 example of a church opposing modern sexual norms. (This is objectively true, regardless of whether you agree with those current norms or not.)

A. Celibate clergy.

B. Official policy of no homosexual priests (despite the fact they are celibate anyway) [1]

C. All-male clergy, and the excommunication of any violators [2]

D. Complete ban on contraceptives

E. Political and moral opposition to same-sex marriage

The Catholic Church's stances on sexuality go far past those of the LDS Church.

I will grant that the Catholic Church is more racially diverse; it's one of the consequences of its vast colonial legacy.

Fluoridation is by no means universal in the US—around 69.2% of public water in 2006, according to Wikipedia[1]. In some areas, resistance is strong and cuts across diverse political orientations. Portland's 2012 attempt to fluoridate, for example, drew opposition on the basis of libertarianism, environmentalism and science skepticism.

It's the difference between just walking to the station whenever convenient and making an effort to time your arrival to the schedule. There is a big jump in UX quality between stressing yourself about punctuality and not caring, because a train will come soon enough.

And it's not just a subjective "good enough" thing where it's not worth optimizing the last few percent: even if you did want to perfectly optimize to the fraction of a second, you'd still want to include some buffer time for unpredictable delays on the way to the station. When the train interval isn't bigger than your buffer then all that synchronization effort is completely wasted.

(PS: not related to your post, just a remark on the wider discussion: it's quite misleading to say "Germany" when referring to a service level that is pretty much exclusive to Berlin)

Geostationary satellites are launched from near the equator and then accelerated into a true eastward orbit when they're put into service (eastward because the earth rotates in an eastward direction and we want the satellite's orbit to synchronize with the earth's rotation). They could in principle be launched from far away from the equator e.g. Florida but that would require a ridiculous amount of fuel to get them into an equatorial orbit. Once they go out of service, their onboard thrusters fire (accelerating the craft in a mostly easterly direction -- not "up"!) which has the effect of raising their orbital height to a graveyard orbit.
> I'm laughing. These are all things companies DO in order to cut costs. The most obvious and legal being the washrooms.

In most places the requirement to have washrooms depends on the kind of business, how much seating you have, etc. So e.g. it might be legal to have no washroom if you have no seating, but if you have seating for ten people then you must have a washroom.

> You can buy off-the-shelf model checkers that do more in industry pretty much all the time.

When you establish actual deep properties, that's news. You can't buy any model checker that verifies confidentiality for actual kernels. At all. There is no such model checker.

Again, if non-deductive formal methods are routinely used to establish comparably deep properties of programs of comparable size (as you claim), you should have no trouble naming at least one example. You don't need research papers to justify that claim, just a few statements of the form "Global Property P of 10k line C Program Q was established by model checker R".

> That's like saying that transmuting lead into gold scales well because we can transmute ten gold atoms in a billion-dollar particle accelerator.

No, not really. NICTA kept tabs on this, and got that producing seL4 costs about 50% more per line of code than other commercial L4 microkernels. While that is a significant expense, there is no order of magnitude difference, much less something in the "billion dollar particle accelerator" territory. Especially since it delivered global correctness properties that are out of reach for any other method.
>gravitational potential ... it does not exhibit quantum properties. The only things in the experiment that exhibit quantum properties are the neutrons themselves.

It is like saying that discrete orbits of electron say nothing about quantization of associated EM potential.

>The only things in the experiment that exhibit quantum properties are the neutrons themselves.

And those properties are position and momentum.

They specifically chosen neutrons to avoid effect of other forces and the paper is pretty clear that position and motion of neutrons were primarily affected by gravitational field, and as result the neutron position got quantized :

"...
we conclude that the measurement manifests strong evidence for quantisation of motion in the gravitational field as is expected from quantum mechanics

...

the quantum theory we derived neglecting gravity is unable to reproduce the shape of the neutron height distribution even on the largest scale.

..."

Do you think the height of observed "steps" in neutron position would be the same or different if the experiment were repeated in different gravity, say Moon?

Utah was definitely not a theocracy at the time suffrage was obtained.

It's actually a fascinating story. Mormons largely supported suffrage, but had to fight the federal government tooth and nail to get it.

In 1869, Utah was under territorial rule, and the federally-appointed government was determined to limit the influence of the LDS Church and end polygamy. The legislature even passed female suffrage during their efforts to rid polygamy from the state.

But it had exactly the opposite effect; most woman voted in favor of allowing polygamy. Thereafter, some national supporters of women's rights actually became opposed to women's suffrage in Utah because of it was being used to support polygamy. (Enfranchisement all fine and well until someone disagrees with you.)

In 1887, Congress redoubled its efforts to end polygamy, and revoked the ability of woman to vote that the legislature had granted earlier.

The LDS Church supported the creation of the Utah Women's Suffrage Organization, to try and restore the right to vote. A Utah Territory judge sided with the women's movement, but the Supreme Court rejected it, citing Congress' law.

Not until the Church renounced polygamy, Utah obtained statehood, and the women's right to vote was included in the state constitution, were Utahns able to undo the Congress' targeted repeal of suffrage.

Utah women then helped secure the Nineteenth Amendment[1].
