roberto··on Ask HN: How to track flying objects?
I've only wanted to add that I'm curious too
roberto··on PRQL – A proposal for a better SQL
This looks great! Clear docs and rationale, and the syntax is well thought. I'm definitely following this.

roberto··on Poll: Why are you staying at your job?
^ 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.

roberto··on It is difficult for the average person to conceive of how useless NFTs are
> I have no cryptocurrencies and feel good every time it goes down because it validates my decision.

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

roberto··on Show HN: Evil Wordle
"Femto (symbol f) is a unit prefix in the metric system denoting a factor of 10−15"
roberto··on Loving Someone with Depression
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.

roberto··on Ask HN: Where are you getting your money's worth?
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.

roberto··on Work/life balance should be difficult
Right, because those are our only options...
roberto··on The Session Extension
NNCP (http://www.nncpgo.org/) can be helpful here as well, in conjunction with the SQLite session extension.
roberto··on Trackers: The Sound of 16-Bit [video]
There are some starter sample kits that you can download for free, eg https://www.samplephonics.com/products/free/wav/hand-picked-.... Should have a little bit of everything.
roberto··on OAuth with Cloudflare workers on a statically generated site
They're not? You're free to not use Sourcehut.
roberto··on Does having prime neighbors make you more composite?
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.

roberto··on Facebook Renames to Meta
- Einstein was a pretty successful physicist.

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

roberto··on Facebook Renames to Meta
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.

roberto··on Perfect pitch study: Why can’t we identify music notes as well as colors?
> 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··on Helm is a personal server that lives where you do
I use https://hoppy.network/ for a static IP via WireGuard for $8/month. And https://mailinabox.email/ has made email administration super simple.
roberto··on A straightforward way to extend CSV with metadata
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: "#"
roberto··on New UUID Formats – IETF Draft
They list ULID and 15 other implementations in the document.
roberto··on Inserting a billion rows in SQLite under a minute
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`.
roberto··on Another 0-day looms for many Western Digital users
> How many times do people need to be burned by closed-source, cloud boxes before they learn to stop buying them?

> Rolling your own remote access solution(SSH/VPN+ strict FW rules) that can be used in conjunction with your own DIY raspberry pi network share(SMB+external drive USB or docked HDD)

These target completely different audiences.

roberto··on Crazy Clock
These mechanisms are super simple to control: just disconnect the board and use a Raspberry Pi or Arduino to send a pair of signals (+ and -) to make the second hand jump one second.

I did an art project back in 2016 with a $2 IKEA clock with a Raspberry Pi and a camera. I used OpenCV to detect when someone was looking at the clock, and when that happened the hands would stop moving, freezing. When the person looked away the clock would tick at a faster race, until it caught up with the right time. One of my favorite projects!

roberto··on Ever-increasing home values are a Ponzi scheme
And how is that relevant?
roberto··on Ever-increasing home values are a Ponzi scheme
The annual population growth in the US in the last 40 years is around 1%, and is diminishing (latest numbers show 0.5%).

The average annual growth in house prices since 1992 in the US is 5.3%.

roberto··on Let web applications be file handlers
They mean progressive web apps, and they exist in other browsers. Firefox, eg: https://developer.mozilla.org/en-US/docs/Web/Progressive_web...

roberto··on Facebook extends its work-at-home policy to most employees
I'd rather have the option of having lunch at home, with my family, than at work with my boss, even if it costs a promotion.
roberto··on Chrome extension recommends local businesses while shopping on Amazon or eBay
Well, yeah.

The point is to sacrifice convenience to support local stores.

You want to do the right thing AND you want it to be more convenient? Sounds like you're just looking for convenience.

Narrator: it was.
roberto··on Tar is an ill-specified format (2015)
