scribu··on A Concrete Introduction to Probability (2018)
It does have a section on continuous probabilities at the end.
scribu··on Over the next year or so, Google will try out new office designs
The Campfire meeting room seems interesting.

Giving remote participants a proportionate physical presence should help equal the playing field.

I think it hinges on how easy it is to set up the call, so that each face is on a separate screen.

scribu··on Self-supervised learning: The dark matter of intelligence
> Judges make harsher rulings when they're hungry.

Actually, that finding is highly improbable: https://nautil.us/blog/impossibly-hungry-judges

scribu··on Rust’s async isn’t colored
Yeah, better to leave out the swear word completely from the HN entry, rather than write a confusing euphemism.
scribu··on Self-decapitating sea slugs regrow their bodies – hearts and all
> The scientists think the sea slugs are using the energy from the photosynthesis occurring in cells that they’ve gained from algae they’ve eaten.

So they have enough active algae cells in their head to power the growth of a whole new body. Incredible!

scribu··on ISO Standard for Preparing Tea
It's called "hate bonding", apparently:

scribu··on Burned House Horizon
> Romanians are very proud of their [...] active Gypsy culture.

As a Romanian, I regret to inform you that a lot of Romanians really don't like gipsies. This has always been the case, unfortunately.

scribu··on Burned House Horizon
I don't see any "belittling" comments here, except perhaps yours.

People enjoy talking about the stuff they read. Discussion is part of how one learns.

If you don't find value in reading non-expert commentary, then don't read it.

scribu··on Square acquires majority of Tidal in $297M deal
Is there any rhyme or reason to Square's moves in recent months?

First doubling down on Bitcoin, now a music streaming service. What next?

scribu··on Tips for Shipping Data Products Fast
Perhaps iterating on the ML model allowed you to learn about the business domain faster or more systematically.

When you're learning something new, you don't even know what questions to ask (unknown unknowns). And the domain experts don't know what to tell you first (curse of knowledge).

If, on the other hand, you present a model to a domain expert, they can start to poke it and tell you what it got wrong.

scribu··on Are You Trading or Gambling?
One better-than-nothing way is to look at historical data:

Looking at the closing price for each trading day, count how many times the stock ended higher and how many times it ended lower than the previous day.

Then you have your odds.

scribu··on Are You Trading or Gambling?
Ah, a lottery on a blockchain. Why not!

Except, unlike a national lottery, you can't trust the issuer and the value of your prize fluctuates even after you win.

scribu··on Changes to sharing and viewing news on Facebook in Australia
I think this article on simple linking vs. previewing sums up the issue:

scribu··on Blue beads could be the oldest evidence of European goods in North America
European settlers reached Alaska only in 1741, so the organic material around the beads - which is what was used for carbon dating - would have had to survive wear and tear for centuries. Not very likely.
scribu··on Don't Mess with Backprop: Doubts about Biologically Plausible Deep Learning
> You can indeed use backprop to train a separate learning rule superior to naïve backprop.

I used to dismiss the idea of an impending singularity. Now I'm not so sure.

Hopefully AGIs will reach hard physical limits to self-improvement, before taking over the world.

scribu··on The Missing Stakeholders
The observation that regulation usually ends up helping the incumbents is not new.

That said, I find the "meshed society" concept useful. It highlights the radical level of collaboration possible between individuals, enabled by the internet.

scribu··on A Framework for Writing Better Documentation
Interesting; they kinda look like condensed pitch decks.

Are they ever used for anything besides pitching, i.e. after a project is completed?

scribu··on Human-Learn: Draw Machine Learning Models
This is a really interesting project. It's a collection of utilities for constructing rule-based models, as opposed to statistical models (i.e. ML).

I can see myself using it for exploratory analysis and constructing baseline models.

As for the "let's just draw the model" idea, it gets complicated as soon as you're dealing with more than one input parameter. The author has some workarounds, it looks like:

scribu··on YInMn, the First New Blue Pigment in Two Centuries
There doesn't seem to be much of a perceptual difference from Cobalt Blue. [1]

The significance is mainly due to better durability [2]:

> the increased UV absorbance and stability in outdoor weathering and heat buildup tests demonstrate that YInMn blue is superior to Cobalt Blue

scribu··on B2B SaaS marketplaces with opportunities for indie hackers
I think that's an accurate summary.

Even if someone starts out as a "one person dev shop", they eventually become a business person, out of necessity.

scribu··on SARS-CoV-2 501Y.V2 escapes neutralization by South African COVID-19 donor plasma
What about "long covid"?

It looks like 1 in 10 people infected experience symptomps for more than 12 weeks. [1]

Just because you aren't likely to die doesn't mean you'd be fine.

scribu··on Addressing the threat from investments that finance CCP military (2020)
Why do you call it a conspiracy?
scribu··on DALL·E: Creating Images from Text
There are several projects like this, but they can only generate abstract shapes, i.e. they're much lower-level than a natural language caption.
scribu··on Shamelessness as a Strategy (2019)
It seems like you're referring to the guilt-shame-fear spectrum. [1] Very interesting!

scribu··on The universe is expanding faster than expected
Yes, apparently that absorbtion of light by intergalactic dust is a well-known phenomenon called interstellar extinction.

There are various ways of accounting for it.

scribu··on Wonder
Don't a lot of philosophers invent new terms, tho?

They want to avoid all the baggage that old expressions accumulate over the centuries and start fresh.

scribu··on Modern storage is plenty fast, but the APIs are bad
> how many servers are running on storage this modern?

AWS allows you to provision EC2 instances with NVMe, without much fanfare. Cost is only ~20% more than SATA.

scribu··on Ask HN: Why can't nuclear waste be launched into the sun?
"For a spacecraft to launch toward the sun, it must accelerate to nearly match the Earth’s velocity—in the opposite direction."

Source: https://www.theatlantic.com/science/archive/2018/08/parker-s...

> If nuclear rockets or reactors are built in space, would this be a possible way of handling nuclear waste from reactors already in space?

If you're not already falling towards the Sun, it must mean you're in some sort of orbit around it. So you'd still need to cancel that out.

scribu··on Competition and Quarter-Life Crises
Competitiveness of any kind, with others or with oneself, whether physical or mental, seems to me like a crutch rather than a path to happiness.

If you can only feel good about yourself when you're on the up and up, what happens when you start getting old and can no longer keep up with the young blood?

scribu··on Spritely – leveling up the federated social web
It's a collection of features meant to sit on top of ActivityPub.

ActivityPub is a general protocol for decentralised social networking. Instead of Facebook or Twitter servers generating a feed for each user, user's servers send updates to each-other.
