> it’s tampons vs a reusable reply device that lasts forever

... but you have to wash it with water and cleaning products, and possibly carry around dirty.

Does it still come ahead? Probably. I don't know. We had this conversation with my wife around cups and reusable pads, and we're still not 100% sure which is the most environmental-friendly option.

I raise this as a general point: I've never seen any good resources to help people estimate full environmental impact of disposable vs. reusable things, accounting both the difference of {emissions, energy, water, plastics} used in manufacturing of disposable vs. reusable item, and then the difference of those in ongoing maintenance.

It's important we learn to figure this out as consumers, because I fear otherwise our civilization will die on lots of bad decisions driven by not knowing the total costs. Things like not realizing you'll have to use a reusable bag a couple thousand times before you're ahead energy-wise over single-use plastic bags (the correct answer here being, treat your reusable bag with respect, and find other ways to reduce packaging churn - otherwise you'll likely lose or destroy your eco bag before you achieve a net environmental win).

(On that note, I recommend watching videos about how things are made - it's a good way to calibrate your sense of how much plastic actually goes into a thing. In case of e.g. disposable trash bags, my brain can't really internalize information like "10 microns thick", but actually seeing the process of making a big roll of plastic film and turning it into unending stream of bags made the relative amount of material involved intuitively comprehensible. Also, videos of industrial machines are relaxing to watch.)
Thank you for bringing this to my attention. These are fantastic!
Haha, they look so cool!

Given that the mesh has an uneven surface though, I don't see how they could compare well to the resistance of a tire with a smooth surface.

Also, it looks like the coating would have to be reapplied often because it's so thin.

And small objects could start to accumulate inside, no?

The more I think about them, the more impractical they seem. Would still love to try them though.
This sort of sounds like 2 clashing sets of anecdotal data.
This is true, but I don't find it persuasive.

We know that simple chemistry plus lots of energy can create more complicated chemistry. We have evidence that some protein molecules can be self-replicating under the right conditions.

Given billions of parallel experiments over billions of years, I think it is vanishingly unlikely that exactly one has progressed to the point we would recognize as self-organizing.

But that's faith, not proof. I'll defend it as the most reasonable and non-exceptional version of the story, but I won't claim it as absolute truth.
Thanks for this writeup. I remember fondly a handful of applet games.

I work for a university press and virtually all of our manuscripts come in as Word docs, but most of our books are indeed in humanities, most are not esp. math intensive. BUt now even Word can handle math markup well enough for say, an economics text. We occasionally get LaTex files, and it is difficult to integrate into our design workflow, they have to be handled completely separately.

If you go back a little bit, there are a few devices that really were forks in the road for the industry. Probably the biggest, most important:

* Commodore Amiga

* Psion PDAs

* Nokia N900

* Motion Computing Tablets (yeah, almost 10 years before the iPhone)

All four were pretty good tech - you could argue that the N900 and Motion Computing devices really needed capacitive touch, but all four ended up in history's dustbin because of business issues.

My stance is: "Cancle culture" does not exist. The behaviour you describe existed before and there is no new development, that indicates the need of a new word. Death threats are not okay and that's totally independent of them being within or outside of something you call "cancel culture". And criticism doesn't get more or less reasonable if it is framed with "cancel culture".
I'm from germany. Here the phrase had a short burst of infamy as a comedian ("Dieter Nuhr") claimed people want to "cancel" him. By now the word is rarely used. And the discussion is better for it.
The only successful "cancelling" I witnessed was a left leaning twitter account, that was about fascism in austria. The woman behind it got death threats against her children and deleted the account. I think the use of the phrase "cancel culture" in this case is playing down the problem.
And if public figures try to silence criticism by the use of the phrase, than it's playing up the problem.
When and where - if ever - "cancel culture" is a useful term I don't know.

It is interesting you call it the "master vs main" debate. The problem is the combination of the words master and slave. You - maybe unconsciously - left the word slave out.

And there is not really a debate. I do not believe anybody was bullied to change that. It was a decision that was made independently. And now in the aftermath people shout about it as if it is utterly impossible that this could have happened without some mobbing or a big "culture" that made this a unjust decision. Because: "I know not a single adult that like that change." Well, maybe the majority likes it. The majority just does not participate in online discussions, so it's invisible. Hard to tell.

Beside all of that, the reason given is an extremely good one. The official server deployment suggests you should have multiple GB of free RAM for it. Bitwarden_rs uses orders of magnitude less. Right now it's sitting at 20MB on my server.
If they transition to white LED lights, it will be a big shame. White light disrupts our circadian rhythm, our sleep-wake cycle. It affects bugs, bats, and all sorts of wildlife. It would be much better for everyone if they moved to red street lights.

In many cases user or players (video games) involvement is really tough to predict. IMO, the best people for that are game-designers and their method is to play test. In other words, we can't predict how users react to particular technologies.

> Some languages that have CONS cells:

Erlang and Prolog also use cons cells... Prolog is also homoiconic. I don't think I ever heard anyone calling Prolog a Lisp though.

Also, Clojure has cons cells. '(3 . 4) is a valid expression in Clojure.

Basically, this is an arbitrary, and rather unhelpful, classification. I don't find it interesting, but to each their own, I guess.
Super interesting. Thank you.

That brings up the other big problem with contemporary TeX. LuaTeX has handfuls of subtle incompatibilities with pdfTeX and XeTeX (and a weird way of handling character setting at the low level where it maps characters to their index in the font file rather than unicode code points). It's also noticeably slower than XeTeX which is slower than pdfTeX. It would be nice if it were true that pdfTeX ⊆ XeTeX ⊆ luaTeX, but unfortunately, it's not.
I partly agree, but isn't that more of an issue about children being barbarians than about school being a barbaric institution?

As you say, adults only have control over superficial parts of these dynamics. I'm dubious that they can exercise more control without extensive restrictions on the youths freedoms and in turn their development. So these problems just seem inevitable wherever groups of children or teenagers meet.

Interesting, I hadn't know that about Teslas. On a Prius you can mount a ~$50 12V solar trickle charger on your dashboard, possibly with some rewiring [1] to keep one of your 12v sockets live, and it's even easier on older trucks. I'd imagine that the smarter the car, the harder it is to make those kinds of modifications. Even so, an optional "solar package" that integrates cleanly with the dashboard (or roof) seems like it might have broad appeal.

And if your only goal is to use it as an excuse to talk to your friends about having solar panels in your car then a small panel makes even more sense -- you can talk almost as much about a small panel as a large one for a fraction of the cost.

It's interesting how early European accounts of Native American tobacco smoking don't seem to bear much similarity to my experiences of tobacco use. In this it describes the Taino becoming "almost drunk" off it. But the only time tobacco made me exhibit anything like that was when I accidentally inhaled way too much of a cigar and became physically ill and delirious. The experience was an extremely unpleasant one involving vomiting, tremors, having difficulty standing up, and slurring speech. But there was none of the "fun" parts of inebriation. I wasn't disinhibited or "loosened up," I just felt like my heart was pounding out of my chest and that I might die. I simply could not imagine anyone putting themselves through that on purpose as recreation.

I also never experienced hallucinations, which is another thing early accounts said Native Americans experienced with tobacco use. I can only imagine they were taking extremely large doses frequently enough that they had been pretty desensitized to it. I can't imagine what cancer rates must have been like!
My local council, prior to recent events in London, decided to turn off all lights after 1am (or thereabouts) "to save money". There was a backlash, and also at the same time when LEDs became more affordable, so the lights are back on, but they're not the same as the good old fashioned orange/sodium lights. The light is more focused on the ground, and it makes driving a little bit more 'interesting' in the evenings. Compare that to the orange lights, where it was more diffuse and even.

Improving the lighting is also at odds with wanting a dark sky for the local wildlife too. It has a noted effect on birds for instance.

Apropos of nothing... I also remember a story about a northern country replacing traffic lights with LEDs and then spending even more money adding heaters because the old lights were naturally warm, and melted any ice that stuck to the lights. Can't find a link to it at the moment.

Tobacco control has been a big fail, all that has really happened is that government and tobacco became co-dependent. People are still dying from tobacco related disease (I've lost close family members to this), and the product is sold everywhere. I would hope we do not model anything on "tobacco control".
Sure, but rather than a vertical slice, do a horizontal slice. How much energy does every country in the world’s mints, bank vaults, etc. use up, including their whole logistical pipelines that wouldn’t be needed if countries didn’t mint+store physical currency?
Looks amazing, looking forward to trying it out.
In a way, yeah it is a better spring steel. Many shape memory alloys, besides their famous shape-changing-under-heating behavior, can also have superelastic properties, meaning they can reversible handle much larger strains than typical alloys (by a reversible phase change in the material). This means they can work as a better spring alloy. https://en.wikipedia.org/wiki/Pseudoelasticity
This is what I struggle with.

The activation, or executive function, is often missing with folks who have ADHD. Things that I have found which help:

1. Set a timer/alarm for you to get up and start.
2. Set a timer/alarm for you to stop and zone out or take a break.
3. Try to keep a list of actions you can take instead of the one you can't start

And be gentle with yourself when you enter the mental state of "I need to get up to do X now" but your brain simply won't let you. It happens and is frustrating, but don't let that feel like a failure. ADHD brains just can be very difficult sometimes. When this "stuck" feeling happens, I try to cycle through other things I could do until I eventually find on that allows my brain to let me get up. It can be as simple as deciding that I should go pet my dog.

Not a damn thing!

Some of us are a lot more concerned about economic and opportunity inequality among people who have already been born then about problems created by climate change for those who can afford to create the next generation.

For many of these folks whose debt is keeping them from starting families, they have accumulated medical debt from having to accept higher deductibles on health insurance plans that they can afford to buy, educational debt to earn an over-priced degree at a university that still supports way too many do-nothing administrators, and huge mortgages from being forced to purchase overpriced homes near where they work thanks to the snob-zoning which has been passed in many of these same real-estate markets by the folks who already own homes and have started families, which they often turn around and try to justify in the name of "protecting the environment."

Some people think it's a good idea to have a distributed, immutable ledger for stuff like this, with the ability to make payments without depending on a handful of individual corporations like Paypal and Visa. The fact that it's "blockchain" is immaterial except that blockchain happens to be the technology that makes it possible.

There's so much knee-jerk opposition to "blockchain" stuff just because some nerds get too excited about it (and some people are trying to get rich off it). It makes no sense to me.
Totally agree. I guess what i am trying to say is that learning rebase is a must and powerful tool but if you are doing the same things again and again you should think about automating them and use your thinking-power and time for non-automated things.

You answered your question yourself. Not everybody has a business-grade server rack at home (bit of an hyperbole but you get the point).

"Why are people wasting their time rebuilding things that already exists ?"
This is very subjective. There are many people (like me) who use bitwarden_rs for exactly the reasons it was created (low memory usage, etc.) so it definitely wasn't a waste of time.
A few years ago I was in the Galapagos and met a German evolutionary biologist who pointed out some fur seals sleeping on the beach. It was a hot day but they were arranged in a neat line to sleep so they were touching.

He explained it was a group evolutionary advantage - if one of them wakes up because of a predator attack, for example, they’d all be woken up and hopefully most of them would manage to get away. I specifically remember him mentioning that dogs and puppies still have a slight preference for sleeping the same way.

I haven’t for the life of me been able to remember the word (or phrase?) he used to describe the behavior and every so often I Google in vain for more information. I can’t even recall whether the term he used was in english or german. Perhaps someone here can point me in the right direction?
Stellar (https://stellar.org/) uses a novel Byzantine agreement protocol (https://www.stellar.org/papers/stellar-consensus-protocol?lo...) which practically eliminates it in comparison.

It is also insanely cheap (like $1... and even that is just "held" in the account and can be released later) to "mint" a new coin and thus is practically perfect for NFTs.

It's seen as sort of a joke in the crypto world by those who are only trying to make a buck (price of XLM, used for paying transaction fees, is relatively stable compared to others) but I think it's one of the few cryptos out there that has a chance of making a real difference in the world long term.

And can someone explain to me what "shape memory alloy" means in this context? Iirc that means a metal that will return to a shape when heated. So I blowtorch these bike tires every few days to iron out dents? Or are these just spring steel, metal that bounces back into shape so long as it isn't push beyond its yield point?

> I have seen Fibonacci being the poster child of the usefulness of memoization and maybe tail recursion, but never parallelization.

That baffles me. I think I've hardly read a paper on parallel functional programming that doesn't start with fib.

Here's example that agrees that it's the hello-world of parallelisation.

https://wiki.haskell.org/Haskell_for_multicores

It's trivial for a compiler to automatically parallelise it - for every binary operator evaluate the two operands in parallel - done.
This is a hard decision to make. It would be considered on the basis of a couple of things. If it is derivate of already existing code, we would suggest not to do that. If it is an original work, then we would consider those.

Having said that, we want to reduce such kind of conflicts happening in the community. So we would try to limit an entire module under EE License rather a part of it.

While he Greek certainly glorified a heroic death, wars still had strategic purpose and were fought with the intention to defeat the enemy.

The battle of Salamis where the Greek defeated the Persians was definitely considered a success at the time, not a failure because they didn't get to die heroically every last man!

But in case of a defeat it is common to spin it as some kind of moral victory. Just see how the British spun the defeat at Dunkerque in the beginning of WWII. But that does not mean they didn't care about winning.

After learning that someone can get your cardiograph with a laser from 100 ft away, I believe the adversarial fight with privacy won't help us nearly as much as fighting for legislation.

I don't believe this at all.

If Jack Dorsey sold the "rights" to the first ever tweet, I'm confident someone would pay at least $1 million for it, even without an NFT involved.

The fact that there's an NFT involved makes it more valuable, because now the buyer can show off in more ways than one. But that's it.

There have always been, and always will be, rich people with more money than sense, who want to demonstrate their great wealth and worldliness by buying silly stuff to show off with.
