skysight-inc/HackerNews huggingface dataset:
From my experience of benchmarking these databases on scientific data (highly regular timeseries) and looking at the internals of both, these kinds types of number happen when answering the query needs crunching through many rows, but the output has few. i.e. the queries are filtering and/or aggregating a ton of input rows, that can't be excluded by indexes or queried from preaggregations.

From what I can tell it comes down to execution engine differences. TimeScale, even with compressed tables, uses a row by row execution engine architecturally resembling IE6 era JS engines. ClickHouse uses a batched and vectorized execution engine utilizing SIMD. Difference is one to two orders of magnitude of throughput in terms raw number of rows per core pushed through the execution engine.

Postgres/TimeScale could certainly also implement a similar model of execution, but to call it an undertaking would be an understatement considering the breadth and extensibility of features that the execution engine would need to support. To my knowledge no one is seriously working on this outside of limited capability hacks like vops or PG-Strom extensions.
Tl;dr: yes, use boiling water on very high end Chinese green tea for best results.

Longer Explanation:

In the Chinese tea tradition, water temperature is referred to by the size of bubbles during boiling (crab eyes = small bubbles (cooler) vs fish eyes = large bubbles (hotter)).

In theory, all water at boil is 100°c, but in practice, there is often a temperature gradient within a kettle and only the gas (the bubbles) is at exactly 100°c (assuming you're at sea level), which is why even some culinary recipes will call for a "rolling boil".

In any case, the strength of the stream when pouring will have a greater effect on the resulting flavor profile of very good green tea than the variation in bubble size, as bubble size is a variance of ~2°c while water can lose up to 5°c in a high slow pour.

Thus, boiling water at crab eyes with a thin slow (but not high) pour is the method used for high end Chinese green tea amongst high level Chinese tea practitioners.
Maine brook off because during the War of 1812 England conquered a huge chunk of Maine and the good people of the rest of Massachusetts were too cheap to do anything about it.
A thanks for adding that, I somehow forgot to add it myself.
I totally can not relate to the article at all. I would never start any activity with the goal of making friends. So much so that I find the concept of 'making friends' absurd. How would one be able to make, to fabricate, friendship?

Friendship is a sentiment I'd develop towards a person I like and value. And from this feeling I become a friend to them. If the feeling is returned, I am lucky and relish the moment of this mutual positive feeling.

If I were to feel lonely I'd start an activity I like. Start playing a team sport. Be a good team mate. Friendship will eventually develop over time when the group is right.

You like intellectual challenges? Join a Chess or Go club. For Chess or for Go. Friendships will develop if the time is right.

I find it very strange to attempt to fill the void by socializing.
The ball of iron would be Earth's core, and between the thin crust on which we live and the iron core there is the very thick mantle.

Nevertheless, the mantle is made of a mixture of iron oxides, silicon dioxide and magnesium oxide, with small quantities of the other elements, so under the thin crust, even if there remain thousands of kilometers until the iron ball, there is nonetheless what is essentially a huge amount of iron ore.

I think that’s the case with any concept in computer science or math. It’s easy enough to explain integration to someone using simple examples like f(x) = x^2 but it gets a lot more difficult when you introduce Stokes’s theorem and differential forms.

Most of the people complaining about monads are not in your situation. They are struggling to grasp even the most basic examples because they understand concepts only by analogy to other things they already know and monads don’t map to anything they know.

That isn't how people usually view luck. If someone says "My success was all luck!", people wouldn't assume that this guy was lucky to be born smart and hard working and therefore worked his ass off to achieve his results with no particularly lucky event happening past his birth. No, they'd assume something like, the guy next to him at a buss stop happened to be this rich businessman and just happened to need something right now, and then that lead to more similar events and now he is the CEO of a big multi national corporation.
What does flagged mean on posts

It's hard to tell how much of the trouble with 2018 was due to the concept of having a major release with several things being updated together, and how much was due to the mistake of setting too early a deadline (by pre-announcing that it would be "Rust 2018" rather than "Rust 2019").
I'm not an expert in this area, but was interested in that story when it happened. Reading commentary from others in the industry suggested that they were, at best, naive in their handling of that contract. Yes charging them was a political act to save face, but they put themselves in that position through ignorance. Quite a different situation from a reporter and responsible disclosure in my opinion.
The flip side of this (from my ~8 years of experience as a technical writer (TW)) is that once you hire a TW the natural tendency is for engineers to relinquish all responsibility of docs. The happy medium IMO is to put some responsibility for docs in the engineering ladder (not as a nice-to-have for promotion but a legit expectation) and to likewise have an expectation in the TW ladder that they cannot do all the docs themselves but rather need to develop systems/processes for collaborating with engineers. Basically what you said in your last sentence, just phrased differently.

Yes, there's a niche part of the left - the new age/hippie types, very high in openness and very low in conscientiousness - that is profoundly anti-science (or perhaps just ignorant of it). They tend to buy into woo-woo of all sorts and buy into science denialism around GMOs and synthetic pesticides. They would also never accept the tentative evidence that marijuana damages the brains of teenagers.

It created confusion, because:

• lumping marketing of cool features with an announcement of a few incompatible changes was easily misinterpreted as all new features requiring a new incompatible edition (while in fact almost all marketed features were already available in the old edition).

• celebration of features developed in recent years under one big event sounded like all these features were brand new and released at once.

For people who didn't follow Rust development, the announcement sounded like Rust suddenly made a lot of incompatible changes.
With the mechanism I'm proposing, you get to keep your identity hidden as long as you are a good citizen of the platform you participate. If you can't stand for the things you say, and they are problematic for the platform you simply don't say them then. In the current system it's exactly the same situation, if your stuff are not O.K. they get removed which is effectively the same as you not saying it.

I don't know why people feel entitled to say something without facing the consequences of it. If you don't believe in it enough to defend your position and put forward your reputation, you don't need to say it.

Why do you need to deceive people? Let's say, you are a racist and feel very strongly to say something about your opinions. Say it and win the argument and improve your life or say it and lose the argument and people can choose not to be associated with you.

That's a fair situation, what's not fair is to annoy people or maybe even harm them from another persona and then pretend that you are something else.

I'll take your biggest question first.

> In your opinion, is there a way to fix this sort of thing?

Yes, it requires patient, reasonable, intelligent people operating in good faith to sacrifice personal comfort, etc. and get involved in politics.

Politics is literally a zero-sum game when it comes to voting as it is currently structured in most of the United States.*

But when people with the above characteristics get involved, it literally moderates the extremism that we decry. No matter the level (local, state, or federal), whether you decide to run for office, helps others run for office, get involved with a party, or find a particular issue, being involved makes a difference. You may not be able to easily quantify, but it does make an impact. You may also be bringing a critical perspective in short supply to the political process too.

> On what rational grounds do you attempt to prosecute or make such things illegal?

I heard four reasons for the 2017-2018 SB 315 bill.

1. To ensure the next time someone shared a vulnerability that made the state look bad, that a D.A. would have the choice to bring a criminal case (which would obviously color perception of the story).
2. To bring the law into parity with Federal criminal statutes.
3. To give the Attorney General a "tough on cyber crime" campaign plank.
4. The banks were asking for help prosecuting criminals.

Here's the final text of the bill that passed the legislature, https://www.legis.ga.gov/api/legislation/document/20172018/1.... The most relevant text are lines 12-14 and the subsection carve outs on line 16-20.

For further context, voter rolls were already public information and can be acquired via a request to the SoS office.

The larger red flags were the default usernames and passwords in the instructional pdfs for the election systems.

Both of these symptoms (and more) spoke to a woefully underfunded or poorly run office w/r/t to IT.

Getting more funds to have properly, well-secured systems takes political capital and there's not a lot of return of that type of political capital expenditure.

The current SoS has an engineering background and I've been seeing much better public facing systems put in place during their tenure.

On a related note (pun intended) I once had a problem with one of these synths and its rubber contact strip. I would hit certain keys then hear a neighbor note or the same note an octave away. I thought there was a short in the scanning circuitry (I had resoldered some joints that appeared weak earlier by a ribbon connector for the keybed.)

Turns out the rubber contact strip was installed inverted. I think this one didn't have notches to make sure it was oriented correctly. After flipping it, notes sounded as expected.

The description of the Turing test certainly alludes to a test of machine intelligence. So to some degree it is appropriate for AI to have a large umbrella.

My problem with the endless battle to define AI is that there are a hopelessly clueless cohort of people with money that chase the term like its their golden goose, and therefore anybody that wants funding needs to market their thing as AI.

And I think a lot of researchers cringe at the wanton use of AI because it devalues the work that they're doing. I just give it the shoulder shrug of approval - "I get it, you need funding too". And from that perspective I really wish that tree-based ML methods and logic programming languages and rule engines were still called AI, because they're really cool but horribly neglected because theyre not the latest thing.
> Sibling comment already addressed this

Both your comments are lies.

Men are 20% of human trafficking. The idea that's not a massive part of the asset is garbage.

The reason men are left out is because the UN is a political tool used to promote careers over good policy. And from your two comments it works.

The reason you would target women and children, is men are generally labour which is generally less harmful to the individual. (Ignoring the complexity of boys trafficked as soldiers)

Of course for organ transplants that makes no sense. But that's back to the bureaucrats and the commentary on OP question. People are not good. They are in this to feel good about themselves. Hence white knight the women and children.
Personally I find another factor of contempt is "failing a reverse Turing Test" where there is such high repetition and little thought that it seems as if they are organic spam bots. The inauthenticity and persistence grating seems to be a common thing given the contempt for Jehovah's witnesses, Hare Krishina's, multilevel marketers and others. Tech support forced into canned scripts are another such example - in computer science terms it seems that the low entropy becomed apparent and raises subconscious red flags.

The infamous "New World Order" conspiracy theorist archetype tends to be negative and full of put downs to their target de jure as the cause of all the world's evils. Even when it is horrifying it draws more of a watching a trainwreck style reaction.

Negativity and putdowns I would classify more as a breeder of disengagement. This is reflected by the impact of negative campaign ads being more reduced total votes than drawing more votes by looking good in comparison.

You will make sure:

- that my clothes and laundry are kept in good order;
- that I will receive my three meals regularly in my room;
- that my bedroom and study are kept neat, and especially that my desk is left for my use only.

You will renounce all personal relations with me insofar as they are not completely necessary for social reasons. Specifically, You will forego:

- my sitting at home with you;
- my going out or travelling with you.

You will obey the following points in your relations with me:

- you will not expect any intimacy from me, nor will you reproach me in any way;
- you will stop talking to me if I request it;
- you will leave my bedroom or study immediately without protest if I request it.

You will undertake not to belittle me in front of our children, either through words or behaviour.

Precolonial New England was mostly forest and was home to less than 100,000 people.

I don't know how concerned those people were with sustainability or with being custodians of the land. But, even if they cared nought about such things, that need not mean that the state of the forest during their reign is not a worthy target for modern-day conservationists.

Village Homes in Davis Ca

Widely viewed as an improvement over plain tract suburbia but not copied anywhere that I'm aware of although cohousing does the same sort of thing on steroids. Reason might be that buyers have selfish insular motives initially and don't see the benefits of community.
Not sure if this is specific to this book, or Apress in general, but it seems absurd that the eBook sells for $29.99, but you can also buy each chapter individually for $29.95?

The $29.99 is more than reasonable as a price for the book. But who would be looking to spend the same price and receive only a chapter? Seems almost like some sort of trick to hopefully get a customer to unintentionally buy only a single chapter.
There's another step in this thinking of smart vs new ideas. You need smart + new ideas + execution/productivity.

I like splitting it into competency and expertise. In my own personal experience, you can be competent with as many languages as you want, but most people can only hold expertise in a few at a time. Generally, your expertise is going to be the ones you actually use daily, because use is the only way to deepen your understanding.

I, for example, and primarily a Java and Python developer during the day, so those are my expertise. Those are the ones I feel confident telling someone to come to me with any questions on, the ones that I know the internals of, the ones I can confidently solve most problems in without having to look much up.

As a web developer in my younger days, I considered myself an expert in PHP and Javascript, but I know that I no longer hold that status with them. I could immediately understand if I were to read anything with them, but to start something from scratch I would need some lead-in time, so I'm only going to call myself competent.

I use Ruby periodically today, but not on important enough things that I need to understand it deeply, so again I would only call myself competent. I'll sure put all of those on my resume though, along with other competencies and former expertise.
First, you edited your comment. Second, you conveniently omit the part where he says he does support disenfranchised people. Third and most importantly, you bizarrely substitute leftist contempt for actual trust. Personally I think this is a pretty selfish statement that involves casting your state of mind and perspective onto someone else with a very negative sentiment.

flew into jfk last week. Got in a taxi, driver didnt want to turn the meter on. Tried to tell me it was $80 instead of the $52 fixed rate + tolls etc. I managed to pay $65, but I had to pay in cash.

the same thing happened on the way back, except my hotel called the taxi, so then the taxi driver gave the bellman $10 and wanted me to give him the $10 he had to pay the bellman (which I did). He also wanted cash and didnt turn the meter on. I worry that if I insist they turn the meter on they would stop and kick me out of the taxi.

And yes Im out of practice. I used to negotiate that we use the meter and I can pay with a credit card before I even get in the taxi.

I have been uniformly cheated by taxi drivers everywhere in the world.

that alone would have me using rideshares even if it was a little more expensive.

Human-Centered Approach to Static-Analysis-Driven Developer Tools

There are two types of people who have received 4.0 GPAs and very high SAT scores.

1. Geniuses. They can look at a calculus text book for 30 minutes and understand calculus and get an A on a calculus test.

2. Reasonably smart people who think that getting a 4.0 is very important, for whatever reason. So important that it becomes their identity. They spend every minute trying to get that 4.0.

I was probably in middle school or high school when I realized that I'm not nearly as smart as #1, but just as smart as #2. It just isn't that hard to realize that the effort to outcome ratio isn't good on being a #2 type person. And more importantly, long term if you go down that path you will be working some shitty job making less 400k a year at 80/hours a week. Because your identity is being someone who is #1, even if #1 means billing the most hours doing tax accounting in the basement of some old building on a Friday night.

* Understand the best practices of those systems otherwise result gets biased.

* Validate the results with experts of those systems before publishing.
