mLuby··on Whistleblowers take note: don’t trust cropping tools
Couldn't Snowden (or someone with similar credentials and reach) provide bulletproof tools for this? Speaking of The Intercept…
mLuby··on Futurist Programming Notes
From the user's perspective, a PS5 appears to launch the most recently played game in about 1 second. A better word would probably be "resuming" than "booting."
mLuby··on The XML spec is 25 years old today
Yep. JS doesn't have a standard library so npm is the best we've got.

And speaking of the best we've got, the XSD validator above is the only one I'm aware of on npm—kind of shocking given how many overall libraries there are.

It speaks to the unpopularity of XSDs among web devs, which is ironic since HTML is XML.

mLuby··on The XML spec is 25 years old today
Here's how JavaScript's XSD validator works:

> A (XSD) schema validator for NodeJS that uses Java to perform the actual validation. Why? Because Java can do schema validation and NodeJS cannot. https://www.npmjs.com/package/xsd-schema-validator

<facepalm/>

mLuby··on My employer is reneging on its remote-work promise
Most ICs and EMs I've talked with prefer remote. I think it's coming from higher up, execs or maybe even VCs. Probably whoever is looking at the ROI on those pricy multi-year leases.
mLuby··on Stable Attribution
I think you're right. However an implied yet crucial belief is that the loss of manual artists (vs creative directors) will not rob us of potential advances in art.

Put another way, it is the belief that the 2020s are the peak of manual human art.

Imagine if we'd felt that way a thousand years ago, or even a hundred. Is it worth being wrong?

mLuby··on Stable Attribution
Does your work eclipse the master you studied? That's too bad for that one master but often they share in your fame. And each artist eventually fades, passing the torch to the next generation.

Have you studied all masters and eclipsed them, without acknowledging them so they can share in your fame? Will you use your untiring, undying skill to flood the market with your work so "artist" ceases to be a profession?

That's categorically new, and worth preventing.

mLuby··on Google testing ChatGPT-like chatbot 'Apprentice Bard' with employees
Household tasks can involve a robot moving with enough kinetic energy to maim or kill a human (or pet) in unlucky circumstances. And we'll quickly become habituated to their presence and so careless around them. Even a Roomba could knock granny down the stairs if it isn't careful about its environment.

You could make the same argument as with self-driving cars, that people already get hurt this way and maybe the robot is in fact safer. But it's still a hard sell that Sunny-01 has only accidentally killed 1/10 as many children as parents have—the number has to be more like zero.

Let's solve automating trains first then we can do airliners.

mLuby··on ChatGPT: The Slickest Con Artist of All Time
Well, if there've been about 120B humans ever, and we speak fewer than 1B words per lifetime, and the average word takes 1 byte to store, that's about a fifth of all data stored in AWS (according to Wolfram Alpha). It's undoubtedly a lot, and yet clearly within human capability. And of course that ignores optimizations that'd certainly drop that high estimate by many orders of magnitude.
mLuby··on Effective altruism has a sexual harassment problem, women say
It goes both ways. Learning to live on a dead world like Mars (or better yet, off-world altogether) will necessarily entail significant improvements in recycling, atmospheric control, and energy management. Those same technologies could be critical to reversing the damage we've done to our homeworld and enabling us to live on it sustainably.
mLuby··on Math breakdown: Anime homing missiles
It's going to be even more wild in space when missiles can glide.

Children of a Dead Earth allowed some simulations around this concept.

mLuby··on Math breakdown: Anime homing missiles
Deep involved simulation you say?

Check out Nebulous: Fleet Command https://youtu.be/Oe-71-3khyA specifically 1min in they show off the missile seeker customization and sprint phase programming. The game is like if you combined The Expanse with Homeworld.

In general I've found the devlogs interesting—same YouTube channel I linked above.

mLuby··on Chinese surveillance balloon spotted over U.S., Pentagon says
Can they Fulton skyhook it down?
mLuby··on Ask HN: Does the HN commentariat have a reductive view of what a human being is?
I agree with your assessment of how it'll go down. However that verdict will in effect be legalizing a categorically new thing.

Software is often built to perform well for expected inputs, yet when given unexpected inputs it may produce bizarre results that when passed to other software create difficult-to-anticipate cascades of failures. The legal system is capable of the same.

mLuby··on Ask HN: Does the HN commentariat have a reductive view of what a human being is?
Fair enough. I submit the following well-known examples to support my assertion. What are your counterexamples?

  Uber/AirBnB facilitating illegal activity but growing large enough to force legalization.
  Facebook et al providing data and conduits to influence elections.
mLuby··on Ask HN: Does the HN commentariat have a reductive view of what a human being is?
That's the technical meaning, not the more relevant culturally loaded meaning.

If I say someone "voted in a prejudiced way," it's technically true if they'd already decided how they'd vote before they did so, but most people would understand my meaning to be that their vote was motivated by bigotry of some kind.

mLuby··on Ask HN: Does the HN commentariat have a reductive view of what a human being is?
In that sentence, prejudiced is a pejorative way to say opinionated.

I assert that existing legal systems do not suffice. Human governments and courts have shown themselves to be near-sighted, slow, and even corrupt when it comes to rapidly advancing lucrative technology (except perhaps when that tech is a weapon).

mLuby··on Concordia students set to launch most powerful rocket developed by civilians
With orders of magnitude differences in money and work hours they can bring to bear on problems.

Is that surprising?

mLuby··on Ask HN: How do you test SQL?
You tell SQL what you want, not how to get it. That's declarative.

  SQL : CSV :: GraphQL : JSON :: React : HTML
mLuby··on I made a website for lonely people, and got >100 people to log their locations
Using Call of Duty (a military game) with voice chat was oddly similar experience. You can match with two other teammates, then you chat as you help each other succeed in the game, naturally building rapport. Then the game round ends and… that's it, you'll never talk to those people again. It's very abrupt and makes the whole interaction feel weirdly transactional.
mLuby··on Cargo airships could be big
Instead of additional mass, you could add additional energy.

For example, a small maglev running around the inside of the vacuum sphere would steady outward pressure on that part of the sphere. Add more trains at different angles to even out the forces.

As a bonus, this kind of "active structure" can dynamically vary its structural strength as atmospheric pressure changes with altitude or weather.

See Orbital Rings for more info.

All good—figured it's better to report it so you could fix it. Thanks.
mLuby··on Toroidal propeller allows a drone to operate more quietly [pdf]
Whoops I meant to write 11, not 9. I haven't actually heard of an 11-bladed screw, though here's a picture of an 11-bladed pumpjet. https://youtu.be/ugSEIiTZ1Pg?t=386

Clarke's first law applies here. Maybe beamed power could help around a delivery hub.
mLuby··on The “Build Your Own Redis” Book Is Completed
I'm curious if you re-use the same tests across different languages? And is it actually on a network or are you pretending?
mLuby··on Toroidal propeller allows a drone to operate more quietly [pdf]
IIRC submarine screws use prime-numbered blades (5, 7, 9) to cut down on harmonics. Perhaps the same would be useful here, though I don't see many prime-numbered turboprops, which you'd expect to benefit from similar noise reduction. Related, I highly recommend HI Sutton's youtube channel if you're into submarines. https://www.youtube.com/watch?v=ugSEIiTZ1Pg

A magnus effect drone may have a decent chance at being quiet. IANAAeroEng but I'd guess that the moving part's interaction with the fluid can be made laminar or at least non-turbulent, and also unlike some propellers, the moving part shouldn't be approaching or interacting with the sound barrier. https://youtu.be/hlmvHfIAszo?t=16

However my money's on ionic propulsion drones since they have no moving parts to make noise. I wonder if the air accelerated through the grids produces an audible hiss. https://youtu.be/UGM4JXVB5FM?t=126

mLuby··on Ask HN: What happens if a nuclear missile is air-destroyed before detonation?
Dirty bombs are weapons of terror, not weapons of mass destruction.

The true damage is caused by societal and economic overreaction from the target: fear leads to expensive security theatre, a desire for vengeance leads to lashing out with expensive unnecessary wars, uncertainty and political instability destabilizes financial markets, etc.

Some diseases are similar: immune system overreaction causes more harm than the actual invader.

mLuby··on High-Earning Men Are Cutting Back on Their Working Hours

mLuby··on Department of Defense: Software Is Never Done (2019) [pdf]
> In a year replete with reports on artificial intelligence, quantum computing, and blockchain, may seem mundane to write about software, but software is the foundation of all things digital, and the Department does it exceedingly poorly.

I take issue with the title. Software is constantly "done" and then new requirements arrive, causing a new version of the completed software to be built. A suspension bridge is considered "done" even if it's getting continuously repainted.
