Retra··on Elegant Error Handling with the JavaScript “Either” Monad
>font that looks like it's been printed on paper with poor ink

Actually, I think it is intended to look like mechanical typewriter output.

Retra··on Where Has the Magic Gone?
One would think one potential solution is to start working on problems we don't actually understand. General AI, algebraic frameworks, high efficiency cross-cutting models, etc. Pie in the sky stuff.
Retra··on This Page Is Anonymous (2013)
Very little of your DNA is exclusively your own. Most of it was passed into you from other people, and by correlating what you have against what other people have, it is not too hard to trace out where you came from and who you are.

I'm pretty sure E3 started being rote 2 decades ago.
Retra··on Two potentially life-friendly planets found orbiting a nearby star
Finally someone with the sense to realize what difference an order of magnitude can make to a decision. Now lets compute how likely we are to die by an asteroid vs how likely we are to die being stranded on a barren, frozen rock 60M Km away from the nearest source of critical supplies.

Their interests can surely be aligned with a minor amount of high-level bargaining.

Those islands are wasteful, expensive, frivolous, and ecologically disastrous. They are not something to take pride in or repeat.
Retra··on The worst morale-boosting gesture I've experienced
There is a name for that. It is "damning with faint praise."
Retra··on India is drying up
>Some things are common enough knowledge that asking for a source is disingenuous.

Yes. But then we invented science and "common knowledge" was proven ignorant time and time again.

>It's like asking for a source to prove the sky is blue or that the earth is round...

Hardly. I can't look out my window and see what the temperature was thousands of years ago.

>This community claims to be one of educated professionals

You're claiming that, not 'the community.'

What is intellectually lazy is not providing information that verifies your claims, and instead preferring to debate the social circumstances of an internet discussion. You're not obligated to provide a source. You don't have to do it. But don't think you're somehow more intellectually honest or hardworking because you refuse to.

If 2 seconds of googling solves this problem, then you should have probably just done that rather than arguing about whether you should need to.

If it rains less, you dig more wells. Why do you think drought and pumping are independent?

You could get their corpses there, sure.

But if you do mention it and make any kind of error, that seems likely to be used against you as well.
Retra··on Technically, Earth Does Not Orbit Around the Sun (2014)
The barycenter is a balancing point. If you were trying to balance two objects on the ends of a see-saw, if you move one object farther away, the balance point has to move toward it (you're actually balancing moments of inertia, which are functions of radial distance.)

If your gravitating objects are in an orbit, they also have angular momentum and moments of inertia.

Irony stops being ironic and starts being an honest picture of what you are the moment you start doing it out of habit.
Retra··on Gorilla Youngsters Seen Dismantling Poachers’ Traps (2012)
We're very highly tuned for amplifying differences in humans. You get to know some people, and you see them as completely different. People also judge children as different from adults, when from a more objective perspective, the differences are fairly minimal. Animals don't stand a chance.
Retra··on Gorilla Youngsters Seen Dismantling Poachers’ Traps (2012)
Nobody yearns to live in those imaginary places, they yearn to talk about them and think about them. The real world is far more dangerous and scary than the most treacherous fiction.
Retra··on Luna – A WYSIWYG language for data processing
I don't know... I look at this and I just see an alternative front-end for a spreadsheet program.
Retra··on My Personal Journey from MIT to GPL
Violence is usually too far removed from the relevant abstractions. It's not difficult to see violence behind everything, because rules don't mean much if they aren't enforced, and it's all too easy to conflate violence with a threat of violence, or a threat of force with a threat of violence, etc.

But that's not a very useful perspective; a well-functioning society filters violence so that it is only applied when things go seriously awry, and most of us should only ever threatened by minor inconveniences. To focus on violence is to be reductive; it is like trying to talk about programming in terms of electromagnetic laws -- yes, computers ultimately run on electricity, and social powers are ultimately enforced through violence, but the abstractions we've built atop those facts are actually very relevant and useful.

Political freedom is not simply about establishing when violence is appropriate. It's broader than that -- it's about the functional ways we can convert violence into something softer without abdicating our ability to govern ourselves effectively.

More to the point, closed source software doesn't need to be 'inherently violent' for it to cause problems. Nothing is inherently violent, and political freedoms are not defined by violence any more than computer programming is defined by electricity use.

Retra··on How to build something that lasts 10k years
Then don't make the place inaccessible. If you're warning people about a threat, you need to show them where the threat is, not hide it.

But is that better than leaving things lying around in unmarked caves? People's curiosity might kill them, but the best you can do is warn them.
Retra··on Project Svalbard: The Future of Have I Been Pwned
But until that point, you might have a good enough product: One that has momentum and requires effort to corrupt, that users are aware of and have expectations about, and that presents value that people otherwise might not have known is possible. Control being lost doesn't necessitate that all the value & impact is lost with it.

Convention and precedent (and tradition) are also forms of hierarchical power. Those who assert them in the course of making a decision exercise power over those who intend to deny them.
Retra··on Rethinking the filesystem as global mutable state, the root of all evil
I have photos on my computer, even though I don't use a photo management application. I have compressed files. I have files taken from other machines. I remove applications. I create my own file formats. Applications themselves are files.

Who owns all the unassigned stuff? The file system. Give it a different name and you change nothing.
