scott-smith_us··on Ask HN: What sub $200 product improved your 2022
Sodastream. I was tilting back five or six cans of diet soda every day. The cost and caffeine were getting to be a problem.
scott-smith_us··on What did Mary know? A thought experiment about consciousness (2013)
You can learn all the biochemistry about a strawberry, but actually _tasting_ one is going to be a new experience. I don't see any need to bring in metaphysics to explain this (in fact, doing so indicates a confusion of ideas to me).

When we describe sensory experiences to one another, we usually do so in comparisons. "It tastes like chicken." "They look like little blue bananas." "It smells like almonds and paint thinner."

Of course there will be a gap in understanding if Mary has never tasted chicken, seen the color blue, or smelled paint thinner.

> ...despite having previously learnt all the physical facts about colour vision...

Well, we _could_ simply include scratch-and-sniff in our physics books...

If Mary never actually had examples of the different colors, then she wouldn't know how to recognize a color when she eventually saw one. But that's because she (and pretty much everyone else) can't synthesize accurate sensory simulations given information like frequencies or wavelengths.

One could imagine a machine that could take the physical description of a color, taste, smell, and stimulate Mary's brain to simulate a sensory experience. No metaphysics necessary.

scott-smith_us··on Show HN: Research AI – AI Writing Assistant
Maybe it's just me, but...

When you're writing anything non-trivial, you ought to have something new and/or interesting to say, otherwise you're just adding noise to the environment.

I can see this being useful in finding ways to rephrase things, improving the structure or flow of a document. But this seems to be suggesting content rather than form or format. Adding content to your writing because it commonly appears in writing similar to yours seems to go against the idea of new and interesting.

That may be good for politicians, but I can see this being misused to 'bulk-up' a small number of ideas or facts into a full paper. On balance, this could easily do far more harm than good.

scott-smith_us··on A Fire Upon the Deep by Vernor Vinge (1992)
> Also everyone should read Vernor Vinge's "Rainbows End"

I often wonder if the AI in "Rainbows End" becomes the "Power" that gets resurrected in "Fire upon the Deep".

. . .

*SPOILER!* There's just a hint of the hidden villainy and ruthlessness at the end of Rainbow. *SPOILER!*

scott-smith_us··on A Fire Upon the Deep by Vernor Vinge (1992)
I've read Blindsight, but wasn't aware of Echopraxia. I'll look for it.

One common disappointment I have with sci-fi is how often AIs or alien intelligence are so close to human intelligence. In the Star Trek universe, every alien species is essentially humanoid with some added prosthetic and makeup. This is understandable in a weekly TV show with a tight schedule and budget. But I've read lots of books where the aliens or AIs not only act human, they think and reason like humans. What a boring waste!

There was a lot to like about Blindsight, but I particularly appreciated the completely alien life forms and their interpretation of broadcasts coming from Sol.

scott-smith_us··on A Fire Upon the Deep by Vernor Vinge (1992)
I was reading through a list of Hugo and Nebula award winning books (fairly late in life) when I discovered Vernor Vinge.

"A Fire Upon the Deep" and also "A Deepness in the Sky" were both astonishingly great books.

After that, I started going through his catalog. Can't recommend enough for lovers of hard sci-fi and expertly-crafted storytelling.

scott-smith_us··on Computers should expose their internal workings as a 6th sense
This makes a lot of sense to me.

MS Windows could really use a "WHAT THE HELL ARE YOU THINKING ABOUT?" feature. From the first version of Windows with networking, a Windows install had a lifespan of a few years, after which simple things like clicking on the Start menu would take several seconds to respond. You expect this when connecting to an external disk share, but it was woven into the OS so that it happened at weird times.

I didn't know enough about Windows internals at the time to figure out why this was happening. After a few days/weeks/months of irritation, I usually ended up doing a fresh install and re-installing/configuring all of my apps.

Just in the last month or so, my Windows 10 development system will sometimes take several minutes to pop up a File Explorer window. Default File Open/Save dialogs are affected as well. I'm not using any shared drives and I disabled the stupid One Drive thing. At this point, a reboot resolves it, but I sense another reinstall in my future...

scott-smith_us··on Three Super-Massive Black Holes Merging Together in Our Nearby Universe
This was certainly true when I was a kid, and "universe" meant "all existing matter and space (observable or not)".

As a youtube-couch expert on astrophysics, I hear "universe" redefined as something like "a bubble of matter and spacetime that is 'quarantined' and can never communicate with the rest of the cosmos" whenever multiverse theory is discussed.

scott-smith_us··on Three Super-Massive Black Holes Merging Together in Our Nearby Universe
...but then wouldn't it make sense to say something like "nearby region of the universe"?

Somehow the word "universe" in the phrase "nearby universe" seems redundant (e.g. where ELSE would it be?)

scott-smith_us··on Three Super-Massive Black Holes Merging Together in Our Nearby Universe
"Nearby Universe"?
scott-smith_us··on How does one get close to mastering software engineering?
There's a quote that I'm too lazy to look up that essentially says software development is the management of complexity.

That, more than any other description, has always resonated with me. Any beginner can create a bird's nest of code that is too complex for even the most experienced developers to fully understand.

I've been at this for 40+ years now, and if I'm struggling to write something, it's usually not because I don't know how to implement it. It's because I'm trying to pick an implementation that will be simple to understand, verify, and use.

scott-smith_us··on The worst volume control UI in the world (2017)
> I know people who never update their machine because of this.

HA!

I was just testing a VR app that has a Windows component when things started failing in VR. I took off my headset and noticed my test machine going through power-on self test.

"Oh crap!", I thought, "a bug caused the system to reboot".

Nope. Just Microsoft deciding it's time to apply some updates. Doesn't matter that I scheduled for a time that I wouldn't be testing.

I've NEVER been able to successfully gain control of this, despite reading up on it and doing all the recommended things.

scott-smith_us··on The worst volume control UI in the world (2017)
I used to work with a "GUI Expert" who designed everything like the 100-radio-button example, except that he didn't line anything up.

I'd look at something he'd done with controls snaking left and right as you scanned down the dialog, and I'd (sigh to myself internally, and) say "OK, go ahead and clean it up and check it in", and he'd look confused and ask "clean what up?"

He was actually UI blind in the same way some people are face blind...

scott-smith_us··on Ask HN: How much do you contemplate per week?
I had one of these when I was in my early twenties. I had been trying to locate a persistent crash that seemed to occur randomly in a modem terminal written in 6502 assembly.

I'd been at this non-stop for weeks, and had been just working and sleeping, poring over and over the code with no clue. As I remember it, one night I was dreaming that the code was slowly scrolling up a screen in front of me, and one line was colored red. I woke up at that point and knew what the problem was. I think I just got dressed and went directly into work rather than try to go back to sleep.

Since then, I've had fresh insights after sleeping on a problem and coming back in the next day, but I've never had another instance of my brain saying "It's right here, you idiot!" to me in a dream.

scott-smith_us··on Spintronics: Build Mechanical Circuits
Every time I see stuff like this, it reminds me of Neal Stephenson's "The Diamond Age: Or, a Young Lady's Illustrated Primer".

If/when technology switches over to the micro-mechanical, we'll suddenly all be scrambling to re-introduce a generation to this 1800s-era mechanical design stuff...

scott-smith_us··on Spintronics: Build Mechanical Circuits
Ah. I wondered about their choice of chain type vs a ball/bead chain. Now it makes sense.
scott-smith_us··on Spintronics: Build Mechanical Circuits
In high school I took electronics and learned enough about capacitors, inductors and transistors to design and test simple circuits. I'd gotten a Radio Shack "100-in-1" kit when I was in fifth grade, but the projects within were all opaque recipes to me. Most circuits had illustrations with cartoons components saying things like "I'm the capacitor, and I give a little 'kick' to the transistor!". I remember being kind of surprised at just how un-enlightening these cartoons were. If I followed the wiring steps for a project and then it didn't work, I'd double-check my wiring. If it still didn't work, there was nothing further to do; I just gave up. I had no idea how it 'ought' to work, so there was nothing I could measure or verify that would mean anything to me.

This is what I wish I'd had at the time. I'd have understood intuitively what each of the components did. The time-scale is slowed down enough that I could see what was going on. I could build and test in stages and see how each new change affects the outcome. Endless experimentation and possibilities...

This is just terrific!

scott-smith_us··on Hungry men exposed to blue light are sensitive to Earth's magnetic field (2019)
I've always said this.
scott-smith_us··on Tardigrades spilled all over the Moon in 2020
Posted stories get so much more love if you don't mind misleading people in the title
scott-smith_us··on The Lab Leak Hypothesis
There isn't any direct evidence that it was leaked from a lab, but there isn't any evidence that it wasn't...

Sheesh. We're in Glenn Beck territory now.

scott-smith_us··on George Orwell is out of copyright. What happens now?
"New, reformulated George Orwell v2"

(since it's an entirely new product, copyright starts over)

scott-smith_us··on Visa and MasterCard Are Trying to Dictate What You Can Watch on Pornhub
> ...accused the website of hosting sexual videos of underage and nonconsenting women...

So, it sounds like credit card companies' main goal is to not support exploitation of underage and non-consenting women.

Pornhub is removing all of their unverified videos because that's the only way both parties can be satisfied that what remains is consenting & legal-age.

I think this title is misleading.

scott-smith_us··on What would happen if computers never got any faster?
> "Mars is the only planet in the solar system which is entirely populated by robots from Planet Earth."

I guess this is really saying that there are no active probes on the surface of any of the other (inner/rocky) planets.

This strikes me as a very roundabout way of saying this; as though the population of the other planets (besides Earth) included humans or alien robots...

scott-smith_us··on Hackers extorted $1.14M from UCSF
It really bugs me when I hear of institutions paying these ransoms.

Regardless of the damage, I'd just take the bullet, fix my security, and not pay. Be consistent in this, and keep it up for a while. Long term: no more extortion for anyone.

scott-smith_us··on Intel exits memory business, sale to Hynix for $9B
Maybe I'm old fashioned, but I'm just glad that Hynix is still intact.
scott-smith_us··on How We Institutionalized Incompetence
> if I free myself from intellectual rigor and data/evidence based claims, and allow myself to focus on emotion, vague statements, and anecdote, I can paint whatever picture I want

Well said. This needs to be carved in granite somewhere

scott-smith_us··on Does new physics lurk inside living matter?
There seems to be a belief among a small percentage of otherwise non-magical-thinking scientists that life or intelligence requires some extra ingredient that isn't covered by chemistry or physics in general.

They assert that no machine can ever be truly self aware or try to draw a fundamental (quantum) distinction between inanimate and "living" matter, or assert that probabilities don't collapse into a single reality until a HUMAN looks at them.

To paraphrase Charles Babbage, "I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a [notion]."

scott-smith_us··on Ask HN: Programs that saved you 100 hours?
BeyondCompare is an absolute workhorse for me. It's kind of amazing how many unrelated tasks involve directory and file comparison.
scott-smith_us··on Ask HN: How do you guys deal with laziness?
LOL. I thought I was the only one...
scott-smith_us··on Ask HN: How do you guys deal with laziness?
I struggle with the same problem.

One trick I've learned is to keep a separate list of "low-barrier" tasks for those times when I just can't get started on something important. I get a big emotional boost from getting things done. Once I've completed one or two of those, I'm sufficiently revved up to start on a top-of-my-priority-list task.

By "low barrier", I mean simple, stand-alone tasks that don't require lots of thinking. A good example might be re-shelving a stack of books or sorting through a small box of hardware. These tend to be very low priority tasks, but it's especially satisfying if they're things that have been on your physical/mental to-do list for a long time.
