This looks great! Clear docs and rationale, and the syntax is well thought. I'm definitely following this.

^ all of the above

I really love my job. I believe in the product (it's open source), coworkers are great, management and leadership are excellent. Compensation is competitive, and I enjoy the problems I'm solving. I have no plans nor reason to leave.

That's like saying "I'm anti-vax and feel good every time someone vaccinated gets COVID".

First, you don't know if they were married, of what their vows were.

Second, you have no idea what they've gone through, no understanding of their pain. If you have nothing constructive to say, no empathy, just shut up.

YouTube premium, to watch videos without ads. As a bonus you get Google's music streaming (YouTube Music) for free.

Hoppy.network, so I can give the Raspberry Pi running in my closet a real IPv4 address.

Monthly donations to Ardour.org, my favorite DAW.

NNCP (http://www.nncpgo.org/) can be helpful here as well, in conjunction with the SQLite session extension.

New comment by roberto in "Does having prime neighbors make you more composite?"

roberto — Fri, 05 Nov 2021 19:32:14 +0000

This is how I understand it:

For every 3 consecutive numbers, one of them is a multiple of 3. If a number has 2 prime neighbors there's 100% chance it's divisible by 3. Without prime neighbors, only 33%.

For 3 consecutive numbers there's a 75% chance one of them is a multiple of 4. The number with 2 prime neighbors has then a 75% chance of being divisible by 4. A number without prime neighbors has only 25%.

For 5, it's 60% vs 20%.

So on average we expect the numbers with prime neighbors to be more composite.

- Einstein was a pretty successful physicist.

- Well, I wouldn't say that... what else did he do other than relativity?

You really think building one of the biggest companies in the world, with billions of users, is just one success?

Building a company with 1000 users is a success. A million is another success. A billion is hundreds of successes.

> If a person had to identify the luminous intensity of a visual stimulus to within a factor of 2^(1/12)

Without a unit this affirmation makes no sense.

roberto — Thu, 19 Aug 2021 17:41:58 +0000

Why JSON? I don't see any benefits in storing `format.txt` as JSON (specially in a file with the txt extension). It just makes editing harder.

This would be better, IMHO:

    csvddfVersion: 1.2
    delimiter: ";"
    doubleQuote: true
    lineTerminator: "\r\n"
    quoteChar: "\""
    skipInitialSpace: true
    header: true
    commentChar: "#"

If you define the virtual table would you even need to do the `INSERT`? Just query the virtual table instead of inserting into `t` and querying `t`.
