XFCE. Supports the tray plugins, has GUI settings, I don't ever have to use the CLI to configure it (actually... I'm not even sure how I would...).

The service won't be available to anybody because of overwhelming unwanted traffic. Now it's available for most potential users. You're speaking econ 101 when everyone else has played out iterated prisoner's dilemmas.

I am not GP, but I don't have a problem with a single contact. What I find really neat is after hours of just one, the vision in my other eye is improved for a while; I can actually see decently from the non-contact eye when I remove the contact.

Cattle grazing is helpful for fields left fallow, but succession planting is far superior in so many other ways. You can mix plants which repel particular pests with those susceptible to them (and other beneficial strategies), topsoil is grown instead of depleted, flowers are present for wide range of season so bees naturally thrive with food always available, you don't need a significant generator of greenhouse gas running around (cows), and it gets more vegetables per acre so it would be good if vegetables were cheaper because we don't eat enough of them.

I have done succession planting in my home garden, but it's definitely not worth the time investment for the food alone. But it's real neat to see your aphid problem disappear as the nasturtiums pop up without any pesticides needed. You can even feed the world with it, if most everyone wanted to be farmers... (as opposed to some Organic practices which is the same mass farming but the pesticides are "naturally-derived")

I have/make rice starch glue. Can you put it on food? How are you supposed to know whether it's food safe?

Okay, so you don't trust LLM, so you go to a website instead. And... LLM-generated pages are SEO'd to get the top links. So you can't trust any website now (shoot, so much nonsense even before LLM, just more obvious to some of us). So basically everything on a computer is untrustworthy, directly from an LLM or not, unless you got yourself a copy of Encarta '97.

So you pick up a book at the local library. Librarians picked some books to order in subject matters they aren't expert in. How do you know those are accurate and safe? If the book says to use rice starch glue, how do you know the author didn't just copy that from an LLM? Or make it up?

Trust is fading entirely.

Maybe ironically, but software and robotics should allow us to scale regenerative agriculture in a way that doesn't leave everyone in poverty. We already have lasers mounted to trailers doing precise weeding instead of broad herbicide usage.

https://www.agtechmarket.net/news/laserweeding (random web search, I don't vouch for this site, it just looks legit at a glance)

Next innovation could be to scale succession planting, which keeps the ground from being exposed in between crops and lets you transition from nitrogen fixers to users quicker, getting more food out per acre while reducing fertilizer usage. But you can't do that with current harvesters and human labor is too valuable to spend on this.

Also take broccoli harvesting, typically you get a few big heads, then it keeps producing smaller heads, but it's not economical to harvest the smaller heads with human labor. Robotic harvesting lets the same plant produce more food per acre and uses the energy needed for new plants instead to keep producing food.

https://www.merriam-webster.com/dictionary/sovereignty

> supreme power especially over a body politic

> freedom from external control

States aren't sovereign. The state legislatures don't even control their Senators anymore. The fiction of "collection of independent states" is just that: fiction. If nothing else, the American Civil War put an end to that. The Senate is just an unjust system which causes California to have to remit 33% of taxes to other states, while those are state's Senators vote to strip the rights Californians wish to have.

Having the chemical in one location doesn't make it active all over, you need to disperse it. Like you need to shake glow-in-the-dark bracelets.

coryrc··on What we lost when we stopped letting kids leave the front yard
It does seem like it. However, there's the game theory problem/positive feedback loop where each parent who defects and drives their kid makes it more dangerous for all the other kids who are still walking; iterate a few times and everybody has defected and is worse off than before.

Perhaps it was culture, but the above loop only needs cheaper cars and more income, both things present in the 70s as the effects of WWII wore off.

There is separation, at least here in the US, where basically all Montessori schools are private and can choose who to take, so the extreme lows aren't present. The other aspect is kids' abilities are masked by how fast kids grow and change; I'd guess a 20th percentile 4-year-old will be better at things than a 95th percentile kid 365 days younger, so the mixed ages still helps both, because teaching helps someone learn and the younger hasn't learned the thing yet. Where when you get to teens, the more capable student in, say, grade 9 will be able to learn calculus so much faster than a less capable student in grade 12, either you make the former waste most of the class repeating concepts they already solidly understand, or you end up leaving behind the slow learner. You're hurting one, the other, or both by mixing them. But that's doesn't mean they can't both be in art class, or band, or shop together.

Socialization doesn't have to solely occur in an academic classroom.

coryrc··on How Shamir's Secret Sharing Works
Had something like this at Google. There's a service running as root (or equivalent) which receives your desired command to run, and it has to get authorization from another user for the specific command to run, then runs it. That makes sense at Google, because those are production machines and have access to LDAP and who is allowed to run a command on a machine is defined by an LDAP group and you would need two of them (or more?) and there's already existing management website this can be shoe-horned into.

Your environment is unlikely to have all of that already, so you'll need to figure out equivalents for all those. But I think you're going to need a local service running as root and it's going to need to be able to tell the difference between distinct human users, if you want secure. Just typos is way easier.

Transportation land area is something like 98% for automobiles, it's not like you could trend more to cars.

Here's things our traffic engineer told me:

1. It doesn't matter how fast the fastest cars are going or how many cars go by a certain point, only the 85pct is used in deciding whether to intervene "and that's the same as Shoreline, and Bothell, and Bellevue, and..."

2. A bunch of people will get pissed and raise hell if you dare take away some street parking to make it safer for people actually using the road. (I saw this around 35th Ave NE in Seattle) And they tend to get their way.

3. The whole city's budget for traffic safety is $10k.

4. In the last four years, the traffic safety program has resulted in a new stop sign.

5. Public roads are for everyone who drives and the people in the neighborhood get no say in it until the 85pct speed is more than 5 over the speed limit.

My biggest problem with number one is obviously 250 extra cars driving past my kid walking to school is 25x more dangerous than 10 cars, but because of 5 the city will do nothing to reduce people from all across the district driving through my little neighborhood to take a shortcut. Expect they'll spend some of that $10k buying signs for our yard which say "kids live here". Wow, thanks.

coryrc··on What we lost when we stopped letting kids leave the front yard
I'm lobbying my city to make it safer to walk to school. But Traffic Engineers care only about the 85 percentile speed of car drivers and not equity in movement. Non-car users are not important in the United States to the only role cities have for managing road design.

"Safe Routes to School" are programs in the US and there's one here in Washington; Seattle has their own partial adoption of this, and I'm hoping to lobby my suburb into adopting it as well.

The school principal won't allow my son to walk home alone because of the traffic, but the traffic is only present because so many parents drive their kids to school.

coryrc··on What we lost when we stopped letting kids leave the front yard
They need to just be banned on public roads. Require what Europe requires for pedestrian safety and visibility. They still have trucks.

Thanks for investigating deeper than I did. I don't know where else to look. However, unlike the post I originally replied to, every homeschooled adult I know is doing better than average, but anecdote vs anecdote isn't helping.

We are supposed to have a REPRESENTATIVE Democratic Republic, but it's no longer representative when you have orders of magnitude difference in representation.

> Right, like how Donald Trump and his 75 million voters get to have more sway of Kamala Harris' voters

They do in the Presidential race (and only because of FPTP and because we don't have i.e. approval voting), but they shouldn't control the House as well (because trump voters don't always vote R for reps).

States aren't sovereign entities -- they can't make agreements with foreign countries that isn't granted by Congress.

Montessori does advocate that, but mixed ages is not mixed intelligence.

You have that backward.

The home-educated typically score 15 to 25 percentile points above public-school students on standardized academic achievement tests.

Vermonters might not want that because they hold outsized influence on the direction of the country, but then they shouldn't pretend to believe in Democracy.

So, yes, 50 million people should have more say over the country's direction than 1 million. We should stop pretending we have 55 mini countries, because the Supreme Court has stopped pretending we have a 10th Amendment.

It's First Pass the Post that causes that. We have maybe 30% is the population that wants guns highly restricted and a different 30% that wants abortions highly restricted. We have something like 52% that want Medicare4All. But we just seesaw between gun grabber and pussy grabber because those M4A aren't the majority of either party primary.

MMP means the person running on M4A gets ranked in the middle by everybody, which is enough for a seat.

There's already a revolution going on and we're losing. They stacked the courts. The blood of innocents in the streets and ICE prisons.

Either we overhaul the system that got us to this point or we concede.

I'm tired of dumbasses in Montana having 50x the vote in the Senate and 4x vote on the POTUS as a Californian. That's not democratic.

coryrc··on A message from President Kornbluth about funding and the talent pipeline
1. That doesn't solve the Senate problem. The Supreme Court has failed to uphold the 10th amendment and we should stop pretending we're actually 55 mini countries.

2. They're probably up for the challenge. But also, that still doesn't solve the disenfranchisement much. My idiot neighbor with the Trump banner (in our 100% Democratic city and county -- Western Washington) will never have his vote make a difference. But if he could combine his vote with some fellow idiots out east, then they could pick the person that most represents them. And either that person will learn to compromise or they can just sit out while others do advance legislation. Just like in better republics.

Our systems are highly undemocratic. A vote in Wyoming is at least an order-of-magnitude more impactful than one in California.

> all the incentives align towards pleasing extremists

Systems create the incentive! Changing the system changes the incentives and is the only way we can reduce extremism.

Learning calculus is table stakes.

While you're almost certainly wrong about "not learning calculus or chemistry better at MIT than in an unknown university", learning happens outside the classroom just as much as within it. Students at random Italian University don't have a connection to people doing the most advanced research in the world. At MIT, that person is there and the people they are mentoring. You can work with those people and learn things that won't be taught in classrooms for at least a decade. That isn't happening at Podunk U.
