ChancyChance··on The largest number representable in 64 bits
You didn’t read the article.

It asks for the largest terminating number.

ChancyChance··on Gamers 50-plus are a growing force in the tech market
WoW floored me, it was what I had always wanted in a game since first playing Ultima (I). The grind and the silliness finally killed it tho (plus trying to wrangle time to play after putting the kids to bed, I got very little sleep for 2 years). Funny you mention LotR online, as my guild lost a number of players to it when it first came out. Didn't know it was still alive and kicking! I kinda lament missing Eve Online, that also sounded fun.

EDIT. Mac support deprecated on LotR. :( And I only use my PC through Remote Desktop... maybe i'll give it a whirl anyways....

I'm so old I can't get the hang of those new-fangled controllers. :)

Whoa, I didn't know that! TIL.

I'm a 50+ gamer and I could care less about refresh rates, any first-person shooters (I guess that's two FPS I don't care about!), photorealism, and dance/emotes. Stanley Parable was probably the last time I was blown away by a game. I'm glad to see more indie titles on Steam, but it is hard to sort through the chaff.

Also: AARP commenting on over 50? /sighs/

ChancyChance··on The magic of DC-DC voltage conversion
I really enjoy articles like this. My job responsibilities require a knowledge split about 67% software and 33% hardware. While I've been building circuits since the early 1980's, I never got the hang of analog in college (yes, I know, "everything is really analog"). I know enough to follow examples and spot issues or contentions or oversights but I don't know enough to do __efficient__ ground-up design, just naive circuits that burn a lot of power or are noisy at higher frequencies (I'm pretty sure I'll never get RF).

Articles like this that start from highschool circuits and move to professional discussion are super useful to refresh my memory neurons. DigiKey has a huge number of articles like this, which walk you from the naive circuit and then point out errors (e.g.: https://www.digikey.com/en/articles/how-to-power-and-control...)

More please!

ChancyChance··on The magic of DC-DC voltage conversion
It's not really clear from this paper, it is more handwavy based on today's circuits.

They claim that the darlington voltage drop is ~2V which is suitable for 5V to 2.5V regulation, and then introduce 100mV with an NFET as low-dropout for cases where LiPO cells are 3.6 V, or 300 mV above industry standard 3.3V (or the new embedded expectation of 1.8V or 1.2V off a 2x 700mV cells).

However, what if I need to regulate 3.35 V to 3.3 V, do I need an Even-lower LDO (ELLDO)? That meants we have HDO (2V), LDO (.1V), ELLDO (0.05V), which becomes an absurdly semantic situation.

I think the confusion is that engineers picked the words and it is based on the technology of a current point in time. In their mind, the breakpoint is NFET dropout of 100mV, which is purely subjective. Although I could also argue that my example is silly because it is within the range of tolerance of most datasheets spec for Vin of 3.3V +/- 1%.

ChancyChance··on Tech bosses are letting dictators censor what Americans see
The unwashed masses that led J6 "did their own research" yet still qualify as brainwashed zombies. There's so much shit in the channels and so much polarization that appealing to people learning how to think critically will fix everything is one of the biggest myths of the 21st century. And in my opinion, this attitude is wildly elitist. Because lets face it, critical thinking is only something a small %age of humans are good at, and I don't include myself it that sub-population and I'm pretty goddamn smart, smart enough to know when I'm stupid.
ChancyChance··on Mortgage Rate jump up, slowing down the buyer market
Hasn't changed a thing in Portland, Ore. Two friends looking for houses still getting out bid by multiple 10k's. Feel bad for 'em hope it changes soon.
ChancyChance··on SpaceX Starship rocket explodes minutes after launch from Texas
Same thing with NASA. There are countless mashups of NASA foibles. SpaceX is the same, just for profit.
ChancyChance··on Yubico is merging with ACQ Bure and intends to go public
Their own hard tokens and authenticator apps.
ChancyChance··on Yubico is merging with ACQ Bure and intends to go public
All three of my banks do not support Yubikey according to their tech support.
ChancyChance··on Yubico is merging with ACQ Bure and intends to go public
I was a big fan of Yubikey (I have 3) until fewer and fewer services supported them, instead switching to authenticator apps. Now I have zero hard tokens, but still four authenticator apps: Google + 3 for banking services that use their own.

The biggest killer was the fact that Yubikey NFC is so awful. I worked with tech support repeatedly, even bought two new keys, and it almost never worked right.

ChancyChance··on The Battle over Techno’s Origins
Yeah my lineage was sort of a quickie to make a rough point, not be a well researched history. Not sure why your text is gray, though!
ChancyChance··on The Battle over Techno’s Origins
Oh, right, I had remembered it backwards, and I didn't realize Eno got it from Riley and Oliveros! I guess my chain of provenance is missing a few. Of course, in the hands of any creative musician, I think it would only take a week or so before they thought about making a tape loop on a reel-to-reel recorder.

https://happymag.tv/frippertronics/:

"In September of 1972, the pair met in Eno’s London home studio, where he had set up a tape system developed by avant-garde composers Terry Riley and Pauline Oliveros."

ChancyChance··on Is there a canonical source for “the argument for AGI ruin” somewhere
I hope at least one of them comments on that.
ChancyChance··on Is there a canonical source for “the argument for AGI ruin” somewhere
That's a really good explanation I hadn't thought of: an example of deploying both-side-ism when both-side-ism is desperately needed. Shrewd, but I wonder if it was intentional or just the outcome of an editing war of egos.
ChancyChance··on Is there a canonical source for “the argument for AGI ruin” somewhere
"Concerns about superintelligence have been voiced by leading computer scientists and tech CEOs such as Geoffrey Hinton,[6] Alan Turing,[a] Elon Musk,[9] and OpenAI CEO Sam Altman."

Oh my, the implications of this sentence are staggering. Equating Musk on the same level of Turing is the definition of a juxtaposition, but that's not even my point: the second juxtaposition is putting inventors of computing theory next to profit-driven egos trying to make a buck. These two layers themselves indicate the table stakes are already tilted in the favor or recklessness.

ChancyChance··on The Battle over Techno’s Origins
Looped music came from Robert Fripp which came from Steven Reich which came from Daphne Orem which came from Edwin Votey which came from ... But if you think about it, who was the first to serve the new music to a large audience and have it documented and then commoditize it is where i think the notion of "first" really comes from. It's like trying define the exact day that Boomers became Gen-X in the US: broad strokes make sense, but resolution is only so fine.
ChancyChance··on 'Algebra for none' fails in San Francisco
Kids take algebra in 8th grade? When the heck did this start? I didn't take it until first year highschool (using US terms).
ChancyChance··on Apple will use 100 percent recycled cobalt in batteries by 2025
iphone 7 representin'

Maybe customers should reevaluate their shopping habit impact on the environment and stop chasing the next new thing?

ChancyChance··on Intel Foundry Services and Arm announce collaboration on SoC design
The only real Arm competitor to Intel servers is Ampere. There are literally thousands of customers to TSMC that Intel can serve, as long as they don't just focus on whales. Gelsinger needs to realize intel isn't in the pole position and hasn't been for a years, but he keeps acting like it.
ChancyChance··on Notes from a Sun Tzu Skeptic (2019)
I find the type of person that is into Sun Tzu is a fairly narrow demographic. I don't know why that it is.
ChancyChance··on The biggest EV battery recycling plant in the US is open for business
How many EV batteries are decommissioned each year, i.e., could be recycled? This company can handle 70,000 per year according to the article, but what is that number out of?

Side note about consumer lithium batteries: The nearest lithium recycling near me is 40 miles away, and it costs $$ to drop of your stuff. I can afford that, but I doubt most Americans properly dispose of their batteries. Heck, I have a neighbor who burns his trash near the road and one time saw him burning a few car batteries in the pile.

ChancyChance··on My diatribe against “skeptics” (2016)
I agree to make a valid comparison exclude gun and car deaths from healthcare statistics. Unfortunately, Horgan has citations, but you don't. So I can't really do much with your claim because without facts it is an opinion. If this were a debate that would score a point, but we're not competing with rhetoric: this should be a forum with facts. Because I *believe* you are correct, but I have no data so it remains a belief: facts would have helped!
ChancyChance··on My diatribe against “skeptics” (2016)
If you would call out the inaccuracies and cite why you think they are, that would be far more useful and helpful to the discussion than just complaining and waving vaguely ... "over there" as where the errors lay.
ChancyChance··on Ask Wirecutter: Can you recommend a not-smart TV for me?
Yes, Roku is full of all that. The ads are minimal so far: they don't pop up while I'm watching things.

I am adverse to a smart TV because it just adds unnecessary setup, GUIs, remotes, and cognitive load. A TV should be a monitor, not a fancy hub with in your face content.

I deduced the path because an ad showed up that was for a recent film on the setup page. I don't have cable. It could not have been planted in the TV's storage, unless the TV was very new. The only way it could have shown an ad for a film is if it had access to the internet, which I had not set up. I didn't bother checking traffic with WireShark. I asked HN and that's how I found out (old alt account from years ago, don't remember and my stylometric match isn't high enough to find it). I returned the TV the next day because it was too small: I had tried to downsize from a 58" to a 30-something-inch but it was too hard to watch. I could be wrong, but that was my report. Encyclopedia Brown and The Case of the Mysterious Movie Ad.

ChancyChance··on Ask Wirecutter: Can you recommend a not-smart TV for me?
Beats me. But that is a great question.
ChancyChance··on Ask Wirecutter: Can you recommend a not-smart TV for me?
TCP/IP over HDMI exists and is in use.

You cannot just "not connect your TV" because if you connect to ROKU which is connected to the Internet, your TV can access the internet.

Source: I bought a TV a few years ago, and it somehow popped up an ad even though I didn't connect it to my WiFi. Did some research, and that's how I found out.

ChancyChance··on ChatGPT is going to change education, not destroy it
Unfortunately there is no way to test if every answer is correct. There's no magic plugin that "solves" this, because this is beyond P=NP.
