just_steve_h··on Your Brain Is Not a Computer. It Is a Transducer
So many words to say so little. In other words, a Harvard PhD in Psychology!
just_steve_h··on The 20x24 Polaroid instant camera
These incredibly innovative industrial processes of the mid-20th Century never cease to amaze me!

I was lucky enough to sneak through the fence and explore the abandoned Polaroid plant in Waltham along 128 before it was torn down. So many miles of metal piping, so many valves, so many Giant Red Buttons!

just_steve_h··on Bigger vehicles are directly resulting in more deaths of people walking
I think the fact that "automotive safety" begins at the headlights and ends at the tail lights is extremely relevant (and frightening).

The safety of cars for literally everyone in the world EXCEPT for the 1-5 people inside that car is not considered.

It was only a few years ago (2016, in Paris) that Christoph von Hugo, a safety engineer from Mercedes, was asked how a self-driving car would handle a "trolley problem" type situation, where the car could either hit a group of pedestrians, or swerve in a way that could injure or kill the driver, and he said, "Save the one in the car."

just_steve_h··on The Peril of Politicizing Science [pdf]
This article begins with the clearly implied belief that "Science" is not political, and degenerates from this false assumption into a paroxysm of wounded cries over the renaming of buildings and other, may I say, even less weighty matters – comparing them to the gulag and mass murder.

"Science" is not a singular object, nor a single method, nor even a set of ideas; what we must concern ourselves with is Science as it is practiced in our society.

Can one do Science without funding? Certainly! Any child with a simple telescope can observe celestial bodies in motion, reason about observations, make conjectures, and test them against more data. But this is a toy example, and this young scientist's influence may extend to a handful of child peers, and perhaps an interested parent.

The "Science" that concerns us almost always includes published, peer-reviewed research. And thus, it is inherently and obviously political. First, and most obviously: how does one become recognized as a peer whose work is eligible for publication? It necessarily requires many years of study, apprenticeship, and supervised practice. Admission to these ranks requires scholastic and social preparation, and is literally subject to the vote of a committee. That we pretend this process operates entirely on "merit" is but one of the many delusions and useful fictions we tell ourselves when we speak of a "Science" that is somehow "not political."

Second, consider not the training of new scientists, but the actual conduct of research. All research must be "sponsored" by someone, in rare cases, by the wealthy scientist themself – the exception that proves the rule. The sponsoring entity always has a material interest in the science it is funding, whether it is to extend the shelf life of canned goods, to more cheaply deposit thin strips of metal onto a substrate, or to meaningfully improve the accuracy of a weapon system guidance module. It is left as an exercise to the reader to discern the various ways that this process is clearly and nakedly "political."

I feared the worst upon viewing this article's title, yet held to a slender hope that the author might address the real threats of using science to achieve political ends, such as that posed by eugenics, or by nuclear weapons research. Reader, my hope was in vain.

We appear to have here another member of our society's establishment who has become too accustomed to unquestioning deference, yelping like a hit dog because, for instance, a presumptuous collection of students and faculty has dared suggest that perhaps UC Berkeley's $70,000 annual grants from the Genealogical Eugenics Institute Fund might be not only better named but more prudently distributed.*

One wonders if there is a corollary to Godwin's Law that stipulates that the first person to draw a comparison to Stalin has already ceded the argument?

*(this happened in October of 2020, you can look up the fund by name).

just_steve_h··on The brain isn’t supposed to change this much
I have a similar reaction as bejelentkezni – why would we expect a specific sensation to always activate the same set of neurons over time? It would seem to me that we are observing patterns in a dynamic system. Their relations to other patterns seem more relevant than the specific substrate members participating in the pattern.

While too simple, I think by analogy of a whirlpool current in a stream: we would not be surprised at all to observe that a given molecule of water participating in the whirlpool pattern at time (t) has only a (p)% chance of being in the pattern at time (t+1).

just_steve_h··on Tool can make photos undetectable to facial recognition without ruining them
Machines are designed, constructed, and built by humans.

If humans are "machines," then who built us?

A passenger photo appears to show exactly this: one blade missing entirely, the adjacent blade broken about halfway.

That's the excuse I keep heading. Then, I find out that the "low consequence" software I've worked on is being relied upon in very consequential contexts.

Can I tell your customers that the software you're selling them is only built for "low consequence" applications?

I'm wading into waters that are way over my head here, but my understanding is that it is possible for software to be provably correct, in the mathematical sense of "proof."

I'm well aware of the admixture of folklore, experience, and caffeine-fueled inspiration that constitutes much of the software that runs our world.

It's unclear what benefit there would be. On the other hand, instantly changing the balance of the aircraft by jettisoning a large mass from one wing would almost certainly make the aircraft uncontrollable.

An American Airlines DC-10 crashed after takeoff from Chicago in 1979 (?), after one engine separated from the wing. At the time, it was the deadliest crash in the US.

Simon (the founder & proprietor of The Aviation Herald) is an incredible force for good in the world. His work on that site, for well over a decade now, is legendary.

I worked at a Large Internet Infrastructure Company for a long time, and saw software development practices that made my hair curl. All I could think was, "Gee, I'm glad we're not working on aviation software!"

Seriously, though: software "engineering" could actually earn the name, if we had rigorous professional standards, regulatory oversight, and product liability.

Yes, cell towers are obviously a function of population density and presence of people with ability to pay.

just_steve_h··on Hacker increased chemical level at Oldsmar's city water system, sheriff says
Is the threat not from a competent nation-state or supranational entity? Is that not the intention of designating power & water & electricity systems as "critical infrastructure?"
just_steve_h··on Hacker increased chemical level at Oldsmar's city water system, sheriff says
> I worry that they'd just find somebody who wouldn't have those scruples, though.

If I may speak slightly out of turn to a stranger, using a possible & currently imagined future person less scrupulous does not modify in any way your obligation, however you perceive it, to act ethically.

…or at least could be wrong.
just_steve_h··on FDA approves first monthly injectable to treat HIV infection
Why is it spreading? Because ACCESS TO CARE is extremely unevenly distributed. It can be extremely difficult for people with limited resources to get proper care.

just_steve_h··on Climate change: US emissions in 2020 in biggest fall since WWII
The biggest takeaway here for me is that we collectively achieved something previously considered impossible: by making different behavioral choices, as a species, we achieved the largest cut in CO2 emissions in 75 years.

It's tragic that only the threat of a deadly disease could compel such a change, but perhaps we may find other levers to help us achieve such widespread beneficial changes in the future?

just_steve_h··on Central Spain records temperatures of -25°C after snowstorm
I know you're being snarky, but it actually IS likely a result of anthropogenic climate change! The north polar region is warming much faster than most places on the globe. Without its usual thick mass of ice, the region isn't cold enough to sustain the usual "polar vortex." Global models have been predicting for weeks that the vortex would split, and a lobe of very cold air would spin off over Europe, causing record cold temps.

The debates are over and we are already living with the consequences of burning up so much fossil fuel. But your snark is, uh, really funny! Ha ha!

just_steve_h··on DOJ fines Boeing over $2.5B, charges it with fraud conspiracy
Boeing's fine is essentially nothing more than a one-time 10% rebate to their largest customer.

(Reference: In 2017, Boeing booked over $22 BILLION in revenue from the US government. https://www.forbes.com/sites/greatspeculations/2020/01/02/ho... )

just_steve_h··on How We Built the GitHub Globe
It's funny that the marketing & design folks keep doing this (IBM in the 80s, Akamai in the 90s through today, and so on). It looks super cool and informs the viewer of very little.

(Full disclosure: I ported a prototype version of my company's globe data viz in 2013 using Three.js - it's terrific! Those folks are the real heroes in this story.)

just_steve_h··on A Game Designer’s Analysis of QAnon
This is a very useful & frightening read.
just_steve_h··on U.S. Treasury, Commerce Depts. Hacked Through SolarWinds Compromise
So far I've seen ZERO EVIDENCE. Reuters and the Washington Post have breathless claims of Russian hackers "according to officials familiar with the matter." Uh huh.

Saying "APT29" or "CozyBear" doesn't make the accusation any more credible.

If multiple US agencies are trumpeting the same story, you really must ask yourself "Why? Why this? Why now?"

It's pretty amusing, in a depressing way, to see how quickly so many otherwise intelligent people can be made to snap to attention and fight the Russian Menace with a few anonymous government claims.

Companies that provide faulty software are "magically" exempt from liability – neat trick!

just_steve_h··on Waymo pulls back the curtain on 6.1M miles of self-driving car data in Phoenix
I believe that the data-collection should be publicly escrowed for safety-critical research such as for autonomous vehicles, therapeutics, and so on.

It's too easy for employees to subtly edit or shape data to please their managers / directors / shareholders. It can be as subtle as "cleaning" the data by removing records with "noisy" or "unreliable" data, or "correcting" outliers.

In the Waymo case, I consider self-disclosure to be self-serving.
