frezik,

It used to be common for clocks to be driven directly off the electrical frequency. The US Navel Observatory would call up generator plants and tell them to slow down or speed up a little to make a correction to all the clocks. I’m not sure if that still happens, though.

frezik,

Plus, if someone needs calculus for their major, they’ll just make them take it again in college. Why build high school math around it?

frezik,

For that matter, why do we read Shakespeare? They’re plays. Watch them as plays or movies. If kids first exposure to Star Wars was by reading the script, they’d hate that, too, and they should.

frezik,

Interesting that you can interpret “30 degrees” in either C or F, and either way you wouldn’t want to have an orgy outside.

frezik,

I don’t like being outside for either one. Actually, I don’t like outside.

frezik,

Yeah, OP has “why do these homosexuals keep sucking my cock?” energy.

frezik,

For many countries, it’d be as easy as cutting a few undersea cables. Two to three cut cables in 2008 brought down most of the Arab peninsula.

As for the US and Europe, things are too interconnected for that to work. That said, the Internet as a whole is more centralized than you might expect from its history as a network that was supposed to be nuclear war proof.

frezik,

High school statistics covers sampling just fine. Some people weren’t paying attention.

frezik,

1 2 + 2 * 6 /

What’s the problem?

Also, you forgot my inlaws, one of whom believes the answer is 5.

frezik,

Protocols using UDP often dial in some features of TCP at the application layer, and resend packets as needed.

The meme is funny and all, but real world use of UDP is pretty sophisticated.

frezik,

It’s a postcard saying “hey, thinking of you!” and there’s a picture of a wulrus on it.

frezik,

And on /r/exjw. There’s a good likelihood that person was kicked out of their family, and their last conversation with their grandmother was not a happy one.

frezik,

I like it better for cooking, especially for sous vide. One degree C is too wide of a range, but 0.1C is too precise. One degree F is just right.

Conversely, grams are way better than ounces for measuring things. My coffee needs 700ml of water. I can get that precisely by measuring 700g on a scale.

Basically, measuring system purity is not a virtue. Flexibility is.

frezik,

The metric system should be redone in base 12, and RPN should be the norm for teaching arithmetic.

frezik,

That’s just objectively correct.

frezik,

Join me in RPN land, where we sit by looking smug while people thought different systems of infix notation debate the right answer.

frezik,

What base 12 gives you is a lot of common divisors: 2, 3, 4, and 6. Base 10 only has 2 and 5. Base 16 only has 2, 4, 8.

The practical upshot of this is that you can divide things evenly in more ways. Particularly when wanting to divide a board into thirds. Having 12 inches to a foot is actually helpful there, though it falls apart as soon as you get larger.

frezik,

You would have numbers 0-9 plus two more digits (could use A and B, but any two symbols will do). The advantage is being able to cut things in thirds and quarters as well as in half. Cutting by a sixth is a bonus, as well.

RPN (reverse polish notation) is a different way of doing arithmetic where the order you write it naturally determines the order of operations. Do you know those Facebook memes where people get different answers for seemingly simple math equations? RPN does away with that. There is one and only one right way to interpret an RPN equation, and you don’t have to remember any order of operation rules to do it.

frezik,

0 to 100 is always easier to remember than any numbers in between. Oddly enough, it’s the metric system that is supposed to be better at exactly this.

frezik,

See elsewhere in the thread, but basically because of the ease of dividing whole numbers.

frezik,

CO2 absorbtion rate over time. It’s not even close.

That said, trees have other benefits in an urban setting.

frezik,

You don’t need to put algae in cities. They can be basically anywhere to absorb CO2.

Trees in cities tend to be carefully chosen for the environment. Are we in a climate where we need to put salt on the road in the winter? Choose trees that can tolerate some salt in the ground.

frezik,

Putting a ton of water on the roof isn’t a good idea, unless it was already rated for a swimming pool.

They don’t need to be inside cities at all.

frezik,

If you believe this, a year working at a Fortune 500 should cure you of it.

frezik,

I’ve peaked inside large private companies. They’re no better than public companies. Turns out, being large means you can’t move very fast.

frezik,

Right, and I think Denathor is a good example. Spends his screen time being an asshat. Very satisfying when he gets what’s coming.

frezik,

Every state has their own rules. Governor might appoint, or there might be a special election, or the seat goes vacant until the next election.

frezik,

“You can’t see me, I got camo. Wait…”

frezik,

I think you pull back the top, then let it go and the spring shoves the firing pin against the primer. Basically a zip gun.

frezik,

After a little range time with this, a single round is all you need.

frezik, (edited )

In the Foldgers Cinematic Universe, these two are siblings. They also give each other looks at the end that said “after we’re done with this coffee, we’re going to fuck”.

frezik,

That has to happen at the state level, as they control how the elections are conducted.

Something I try to drum up in these sorts of threads is that your state and local elections can be far more important to pushing progressive policy than federal elections. Most of the work for high speed rail, for example, has to be taken up by state government. The federal government might offer some funding, but they only hold that out there for states to choose to take or not. Same with bicycle lanes, housing, or diverting police funding into more comprehensive solutions. That’s all state and local government.

Voting for Democrats at the federal level is merely to keep some of that funding sitting out there, and to not actively block progress otherwise. That’s it. That’s what voting them into the White House and Congress is for. The rest needs to be done in your local community.

frezik,

Factorio-like game where you focus on sustainability rather than being the bad guy in an alien landscape. Need wood? Better replant or there won’t be anything for higher levels of the game. Need metal? You can get it, but only in a few places and then you need to think about recycling what you have.

frezik,

There was this other time they discovered a whole fucking Dyson Sphere, and then promptly forgot about it.

frezik,

A big door shut, but they also knew how to open it again.

frezik,

That metaphor is . . . not entirely wrong.

frezik,

Nonsense. It’s a simple continuation of something that has always been around. They would have needed to actively and purposefully changed it. The first company that tried to sell “1 Megabyte/s” instead of “8 Megabits/s” is shooting themselves in the foot because the number is smaller. If it was going to change, you would need everyone to agree at once to correct the numbers the same way.

Modems were 300 baud, then 1200 baud, then 56.6k baud. ISDN took things to 128k baud, and a T1 was 1.544M baud. Except that sometime around the time things went into tens of k, we started saying “bits” instead of “baud”. In any case, it simply continued with the first DSL and cable modems being around 1 to 10 Mbits. You had to be able to compare it fairly to what came before, and the easiest way to do that is to keep doing what they’ve been doing.

Ethernet continues to be sold in the same system of measurement, for the same reasons.

frezik,

It has plenty to do with engineering, because it was engineering that first decided to measure things this way. Marketing merely continued it.

frezik,

It’d be a tremendously stupid thing to do. Unfortunately for everyone, Xi Jinping might just be that stupid.

frezik,

To expand a bit, you look up the isotope, look at their decay products, and then look up their decay products, and so on until you get to a stable isotope (usually lead or iron).

frezik,

People used to argue that Python was incredibly readable. Then I started seeing shit like this.

frezik,

It jams far too much on one line. Break it up. It’s a mistake I see a lot on Python.

frezik,

Unless you’re looping over more than a million elements, that’s a poor excuse.

Judge finds evidence that Tesla, Musk knew about Autopilot defect that led to killing of Florida man (www.reuters.com)

Bryant Walker Smith, a University of South Carolina law professor, called the judge’s summary of the evidence significant because it suggests “alarming inconsistencies” between what Tesla knew internally, and what it was saying in its marketing....

frezik,

And now the result of that trial could be a verdict with punitive damages.

Hitting them in the pocketbook is a start, but this should rise to criminal liability.

frezik,

Even if it’s a fake effect, I’d still buy the first flatscreen that does this.

frezik,

For that matter, they didn’t even use it well at the time. Their accuracy of jumping with the spore drive was shown to be good enough that they could jump inside the shield bubble of every Klingon supply base, launch a bunch of torpedoes, and get out. War = done.

frezik,

Could you imagine a Voyager where the ship is no longer constantly running towards home? One where they have to stay and gather materials to get their warp 10 drive working. The species they meet will be the same species around a few seasons later, and the relationships they build with them matter. Maybe stasis isn’t good enough, and they have to hold everyone in a transporter buffer, which means rebuilding huge sections of the ship to support having all the crew inside transporters at once. They expect this to take years, but it’s still by far the shortest way home. A few shuttles get modified and they send couriers back to the alpha quadrant. So they have some contact with Star Fleet, but it’s not as simple as opening a channel.

If there’s only enough story material here to support a few seasons, then maybe something comes up that means they have to go back and fix it. Maybe some Borg shit. Make up a reason to keep the Maquis crew around (not like Star Fleet gives a shit once the Dominion War is underway).

Good thing they never gave us that nightmare of a show.

frezik,

Is this sign language universally known in Hyrule? Why don’t we see anyone else using it?

That seems a bigger leap than just assuming he talks.
