bloaf··on Technical Solutions versus Processes
The fastest, most bug free code is the code that doesn't need to run.

The most consistently implemented procedure is the one that doesn't require anyone to do anything.

I agree that when looking at a process that seems bloated and inefficient, we should be mindful of the XY problem: https://en.wikipedia.org/wiki/XY_problem

In my experience most procedures are created not due to a deep nuance to the problem space that makes procedures superior to automation, but rather one of the following:

1. Leadership lacking the technical background to understand what automation would look like or accomplish. (In extreme cases, this can manifest as people creating processes that are redundant with automation capabilities built into the tools they are already using.)

2. Leadership lacking confidence that the organization has the skills or resources to automate effectively.

> Bloaf, it's the employee's job to bring the case for automation to their leadership...

3. People in senior technical roles shooting down automation efforts because a significant amount of their expertise is "expertise in navigating existing processes" and they don't want this expertise to be undermined.

> People are buying cars because they're better than horses

This is only true for people with a certain amount of spare money to pay the extra, since cars are more expensive to purchase.

"According to Kelley Blue Book, gas cars averaged $48,681 that month" whereas horses typically cost between $1500-$10,000 https://www.joyfulequestrian.com/how-much-does-it-cost-to-bu...

AAA reports that average annual operating costs for a car are ~$8500/year https://www.aaa.com/autorepair/articles/what-does-it-cost-to...

Whereas the average annual cost of a horse is under $4000/year https://cowgirlmagazine.com/cost-owning-horse/

bloaf··on You can't tell people anything (2004)
I think this is related to the AI alignment problem; our human languages simply aren't precise enough to communicate with any guarantee that our intent will be correctly conveyed.
bloaf··on Ok, it’s time to freak out about AI
> What is the worst that can possibly happen as a result of AI being able to generate text that is indistinguishable from something a human wrote? Or that a "chat bot" can answer questions with more relevance and detail (correct or made up) ?

Remember the holodeck in Star Trek? Everyone thinks that's cool technology and not really particularly scary. But in reality, the existence of a holodeck is an existential threat to humanity: if you can have literally any experience you want in a holodeck, there is no reason to invent/do anything else.

AI text generation has a similar flavor of danger. Imagine a world in which everyone has a personalized better-than-human text-generating AI. People will have no incentive to read anything other than what it writes (why read Shakespeare when you could have Shakespeare-tailored-for-you?) People will have no incentive to broadcast their own words over those of their AI.

Obviously text is a small subset of the "literally any experience" offered by a holodeck, but it is not hard to see a future in which everyone is MITM'd by text-generating AIs.

bloaf··on Twitter restricted in Turkey in aftermath of earthquake
There is/was an active disinformation campaign on Twitter attempting to link the earthquake to Türkiye denying Nato expansion. The ridiculous conspiracy theory is that the US used a HAARP system to cause the earthquake in retaliation.

Not saying that's the reason for the ban, but twitter is not solely a force for good here.

Giac/Xcas is slightly worse at symbolic integration than Maxima, and both are dramatically worse than Mathematica.

FriCAS, an Axiom fork, is the best open source CAS on those benchmarks.

bloaf··on The unequal treatment of demographic groups by ChatGPT/OpenAI content moderation
I agree. The hate metric is calibrated against responsiveness to insult, not a ranking of social advantage.
bloaf··on Do we live in a society without a counterculture?
The mainstream culture of the hippie's day would have said, with just as much disgust as you hold for the 4channers:

> The hippies are rooted in things like naiveté, lust, drugs, immorality, communism, apathy, and atheism.

There is a sense in the more liberal communities that cultures are good-by-definition. They do mental gymnastics to ensure that any harmful cultural artifacts (e.g. slavery) are explained away as "not really culture, but a product of external forces" (e.g. imperialism).

I have never felt the need to do this: some cultures are on-the-whole bad, and that does not disqualify them from being cultures.

bloaf··on Before you believe the ChatGPT hype, ask it something you know well
Kids are like that too. There was some study that found ~50% of kids thought french fries were made from animals.

The correct conclusion is not that 50% of kids are dumb and 50% smart. Actually, none of the kids knew but they had a 50% chance of picking the right answer at random.

Knowing what you don't know is an "advanced" skill many adults haven't even mastered. I'm not at all surprised chatGPT struggles to not-answer questions on things you just made up.

bloaf··on Before you believe the ChatGPT hype, ask it something you know well
I mean, pose that question to some random dev with little exposure to second life and you'd probably get an even more anemic/generic response.

It's weird to me that people seem to expect current AI to be as good as an expert, especially at something as subtle as the intersection of society and technology. The hype around chatGPT is not that it's an expert in all things, it's that it's a novice in all things, and better than that at some.

bloaf··on How to Be 18 Years Old Again for Only $2M a Year
One thing I've wondered about if someone were to actually succeed at making themselves look and feel 18 is how our legal system would react.

Imagine trying to buy a house when your face says 18 and your ID says 78.

Getting a drink at a bar? Showing ID to vote? Withdraw money from that 78 year old's account? Collect social security?

You're going to get denied at best, and likely accused of identity theft/fraud.

bloaf··on Wolf 1069B: Earth-mass planet in the habitable zone of a nearby, low-mass star
So I thought this would be big news, so I did some reading. Turns out that in like the past 5-6 years we've gone from "who knows how many habitable zone planets there are" to "we're finding them all freaking over the place!"

Does anyone have a good blog/news site that covers topics like this? Because evidently I'm missing out.

bloaf··on Japan’s business owners can’t find successors – one man is giving his away
This is a popular take, but I'm not convinced. The world has counterexamples to both your claims and the "overpopulation/abortion" claims made by conservatives.

Scandinavia has very strong social programs for new parents (as well as "abortion on demand"), but only slightly higher fertility rates than Russia (which has less generous parental benefits, but fewer abortions than Scandinavia). And indeed, the fertility rate in the USA are in the same ballpark, despite the US having no parental benefits.

(Scandinavian fertility is 1.8-1.9, Russian fertility is 1.7-1.8, USA fertility is 1.8-1.9, all in 2021 numbers from Gapminder)

(Scandinavian abortion rates are generally above 15%, Russia is ~12%, and USA is ~11%)

Edit: Data caveats there are some sources claiming russia's abortion rate is >50%, but they seem to be confusing the abortion rate with the abortion ratio. Also, the abortion rate in Russia has evidently undergone a precipitous decline since the 90s, so the abortion rate can look much different if you get/use a source that is even a few years old.

bloaf··on No Other Options: Newly revealed documents depict Canadian euthanasia regime
I think it is more analogous to the laws prohibiting people from selling their own organs. The problem isn't that organ transplants are immoral, the problem is that allowing it can create perverse incentives especially for disadvantaged groups.

If you squint at MAID one way, you can see all the good it does for people who really need it. If you squint another way, you can see the medical system just killing off the people it failed.

bloaf··on Songtell
I agree, just think about how many people play Leonard Cohen songs (esp. Hallelujah) in religious/spiritual contexts and completely miss the heavy eroticism.

I checked out "Show me the place" which is incredibly erotic. Leonard asks to be shown "where the suffering began" (painful childbirth is the first punishment God mentions for Eve) and "where the word became a man" (i.e. where Jesus was conceived-Mary's womb) because "his head is bending low." The AI, just like a lot of people, can't get past that use of religious terminology to realize the sexual innuendo.

bloaf··on Not-so-great features coming soon to Windows 11
Rings true for me, I'm about at the reinstall stage with my HTPC. It will no longer send audio via HDMI due to some deep obscure pipewire config that broke itself without me touching anything. It also no longer connects to my Bluetooth keyboard on 2/3 of the keyboard's channels (actually it connects and disconnects very rapidly, several times a second, but is unusable regardless).

There was definitely something going on last night too, I noticed a number of sites having intermittent issues confirmed by down detector.
bloaf··on Stable Diffusion 2.0
My point is that there is precedent for governments requiring companies to implement restrictions on what images can be handled by their software.

As I explained: This kind of mandated restriction is looming over AI. Companies are trying to get out in front of these restrictions so they can implement them on their own terms.

bloaf··on Stable Diffusion 2.0
They know they are going to be the next target in the war on general purpose computing. They're trying to stave it off for as long as possible by signalling to the authorities that they are the good guys.

A confrontation is inevitable, though. Right now it costs moderate sums of money to do this level of training. Not always will this be so. If I were an AI-centric organization, I would be racing to position myself as a trustworthy actor in my particular corner of the AI space so that when legislators start asking questions about the explosion of bad actors, I can engage in a little bit of regulatory capture, and have the legislators legislate whatever regulations I've already implemented, to the disadvantage of my competitors.

For people who say "people can make whatever images they like in photoshop," I will remind you of this: https://i.imgur.com/5DJrd.jpg

bloaf··on Death by Crowding
https://www.youtube.com/watch?v=XcawqEpIRVo

> A few people rushed and it was only a few

"It's just the thugs and the scabs fooling you"

A man grabbed his daughter and carried her down

But the thugs held the door and he could not get out

> And then others followed, a hundred or more

But most everybody remained on the floor

The gun thugs they laughed at their murderous joke

While the children were smothered on the stairs by the door

> Such a terrible sight I never did see

We carried our children back up to their tree

The scabs outside still laughed at their spree

And the children that died there were seventy-three

bloaf··on Zip Function Solution: Haskell, Elixir, JavaScript, Python, Vlang
In TCL, zip functionality is built into the foreach loop.

     foreach x $list1 y $list2 {
         lappend result [Myfunc $x $y]
     }

To directly return a list of outputs without having to append to a list, TCL also provides lmap which works the same way:

     lmap x $list1 y $list2 {Myfunc $x $y}

But wait there's more! Foreach and lmap also support taking more than one element from the list each time:

     lmap {x y} $list1 {Myfunc $x $y}
