I've been trying to start The Starlost, and now I have the motivation to. Thanks

Oof, this one hurts.

Everyone knows him as Chekov, but I loved him as Agent Bester on Babylon 5, where he played a ruthless and complex villain character. https://www.youtube.com/watch?v=s72fJb7a-s8

RIP Walter

Thanks for the laugh today

I know, carry around a keyboard-sized keyboard? How preposterous. :)

Everyone knows keyboards are carried in a hefty sack, like an old baron with their gold coins...

Don't worry, I was assured all the problems are because gambling is illegal, not gambling itself.

Extremely cool!

Another commenter mentioned[0] that often ergonomic keyboards aren't columnar, but staggered. What if for the pin layout, instead of this:

    1  1  0  0

It was this?

    1  0  1  0

Then the keys could connect with at least two wires in either columnar or 50% stagger, using the same pins. Each key has a maximum of six neighbors instead of four, but that shouldn't be too much trouble.

Naturally if you expand to 6 pins it could support 0/33/66% stagger positions.

More cool, I think, is that it doesn't have to be aligned? You could imagine shifting the pins and mechanism over from top to bottom, so it's a 20%/70% stagger. Maybe that would make it structurally stronger, like how bricks are overlapped?

Very inspiring project, thanks for sharing.

  >abliterated models where the superficial instructions like not describing Taiwan as independent are burned off

Does this help with issues like including security vulnerabilities when you say you're in Tibet? I understood that this was burned in at the training level, not just a layer of censorship added at the last minute.

The person being quoted here, all they do is design cosmetic plastic for the front-end of the existing Chevy Silverado, since the GMC Sierra is a rebadge. They have no say on how tall the vehicle is.

Who said all spelling reforms are the same? Nobody. My point is that saying English has had no spelling reforms is inaccurate.

You're loudly agreeing with me. ;)

If they had said English has had no centralized or universally accepted spelling reform, then I'd have to agree with that statement! But they said English has had no spelling reforms, and that's clearly untrue.

English never had a spelling reform? Noah Webster might beg to differ...

Maybe you meant a "complete" spelling reform, but hardly any reform is 'complete' if you look at it closely.

yes! Many people make these DIY filter boxes themselves, usually called CR boxes[0], which come in (quiet but pricey) PC fan and (louder but cheaper) box fan flavors.

Do note that the AirFanta uses 140 mm fans, and IKEA filters are E12 vs E11 so the airflow would be less optimal[1], but hey who's counting. ;) Also I envy how cheap your IKEA filters are; in the US they're $18 & $25 now.

  >I think the argument is that OpenAI should have done the work of cleaning up the proofs in the first place

So the complaint is, OpenAI didn't replace the role of human mathematicians.... enough?

If this gets 'fixed,' I highly doubt the math community would be any happier.

  >Perhaps I shouldn't have said "think are important" but instead said something like, "are emblematic of some problem but are actually insignificant to that problem".

No, I got your meaning! My goal was to create a good emblem. ;)

  >It's basically, "I'm not jealous, I actually just care about the environment!"

Of course people are jealous. Should they not be? Jealousy is an adaptation to dysfunctional resource hoarding in social groups.

That doesn't invalidate the fact that wealth inequality by itself is also (oddly) bad for the environment.

I highly recommend going back up and watching Donella Meadowa original talk on this. She explains it much better than I could! Cheers and salutations

Paid bounties. Device program. Early access. How is Apple not "playing ball" here? Isn't that exactly what researchers asked for?

Apple has safeguards to avoid selling exploits to criminals that attack Apple's own customers. Good. I wouldn't want Apple to "play ball" like that.

Not BYO, it does come with filters.

If you were actually looking for an answer, the AirFanta's creator Adam Wong recently answered a question about this:

  Production costs include raw material procurement (my fan and filter suppliers are happy, since each machine requires four fans and four filters—more than they supply to other brands) and labor assembly costs. In addition, there are shipping costs from China to the US, Europe, and other regions, warehousing fees, and last-mile delivery fees. For what it's worth, in the US, shipping this 17 lb box already costs about $18. Also, Shopify and credit card channels take just under 5%. We also hope to promote on Amazon in the future. Estimated advertising costs are 20%, and Amazon charges another 15% in fees, so that adds up to 35%. If you're not in this business, it's normal not to know these expenses. But I have to say, the costs are much higher than they appear on the surface.

Ahh yes, that old CO2 cognition scaremongering.

Let's just say, if you look closely at the meta-analyses, all the effect size goes away if you omit one certain author....

If true, SAT scores should systematically vary by hundreds of points depending on which room you take it in. This is not observed.

Perhaps surprisingly, I agree! But those are the things people actually complain about on social media etc.

Why? Partly because paper straws are accepting a significant comfort compromise for a tiny (supposed) environmental benefit, and vice-versa for private jets. Your lips will feel like you're licking a dry stamp every day for the rest of your life, thank you for your service, meanwhile I'll be emitting a year's worth of pollution in one day for more legroom.

Paper straws and private jets are indeed a small part of the total environmental problem (we've all read Without Hot Air), but I think those two examples best illustrate why people feel the unfairness so sharply.

My dog gets stressed out by fireworks, even if she wasn't sleeping. Being startled by a loud sound isn't fun, right?

I expect there are more complex stress response mechanisms at play here, not just disturbed sleep.

  >if you are blowing fresh air into a room, or have the windows open, the filtration effectiveness of these units approaches zero pretty rapidly

Even with an open window, if (say) the air purifier and the window have a flow of 200 CFM, then the air will still be twice as clean (ie half as many pollution particles). I would say that's still worth doing!

Most people would just leave the window open <1", which keep CO2 down yet air purifiers still work well.

75% refers to the Most Penetrating Particle Size (MPPS), so they intentionally measure at the worst-case size so you don't have that problem. All other sizes are filtered at a higher percent.

I call it the "paper straws vs private jets" problem.

It's often overlooked that large wealth gaps are incompatible with a sustainable society. High prices will save the Tuna from extinction (economists were right!), except if there's a market for $10,000/plate sushi.[0] People are motivated to live efficiently, except if we see gross unfairness in the rest of society.

"Don't use trees faster than they grow" is the obvious part of sustainability. This is less obvious but no less important.

  >Forbin defiantly responds "Never!"

  >And that's it.

Funny. In the British original, the book abruptly ends with Colossus's retort to Forbin:

  "Never?"

British vs American sensibilities, I expect.

  >you get to look at any collected dirt

If that's your biggest worry in life, seems like a high-class problem! Many people are satisfied 'just' protecting their heart and lung health.

However, if you really don't want to look at it, you can always flip most DIY designs inside-out so the fans blow in and dust collects on the inside instead of the outside! This doesn't clean the room quite as efficiently, but if the appearance of dust is a major concern that should be a fix.

Them too! Thanks. :D

YSK on low you won't be getting much air cleaning power. All air purifiers are rated based on their top fan speed.

Housefresh, which is a criminally underrated review channel btw, recently did a comparison of PC fans for this purpose. The Thermalright TL-14C family came out strong in the "Silent" category, with the best ultra-quiet 24/7 fan speed performance. This comes at the cost of slightly worse max speed CADR vs the venerable Arctic P14.

  >Of course, the problem with this is you are just spending more money on filters, which is the expensive part.

For up-front cost, this is true.

For cost over time, twice the filters means twice the replacement interval, so the additional filter cost cancels out.

This is indeed the "conventional wisdom," but if you do the math it turns out this is incorrect.

The trick is to use high-airflow MERV 13 filters (ideally 3M 1900, which has high pleat count and low resistance) instead of high-resistance HEPA filters, so axial PC fans can generate enough pressure.
