From Chapter 2 "Teaching for Equity and Engagement" p40:

> Ms. Ross teaches fifth grade at the Jackie Robinson Academy. She has been focusing on developing her students’ sociopolitical consciousness through language arts and wants to bring mathematics into their thinking (SMP.1, 2). To begin the process, the class is led in an analysis of word problems from their fifth-grade mathematics textbook (NF.1, 2, 4, 5, 6). Ms. Ross selects three word problems to connect with the class’s current read-aloud of George, a novel by Alex Gino that shares the story of a 10-year-old transgender fourth grader and her struggles with acceptance among friends and family. In doing so, the teacher is reflecting the recommendations of California’s Health Framework, which suggests that sensitive discussions of gender are important for students

> The word problem analysis serves as a springboard for students to investigate their own questions. One student asks, “Are there word problems that have a male knitting a scarf, cooking, cleaning?”; and another ponders, “Does the textbook always use girl names for girl stuff and boy names for boy stuff?” Lastly, another student asks, “Are there word problems that challenge gender stereotypes?” When examining the entire textbook, the students noted that there were a few instances of gender-fluid problems (e.g., David’s dad baked a dozen cookies to share with him, his sister, and his mom); however, the problem continued to conflate gender with a heterosexual identity. The class could not find problems involving non-nuclear families (e.g., two moms, a single dad) or gender nonconforming characters (e.g., John cutting ribbon). Ms. Ross has students notice these patterns, but also asked students to question why certain items (e.g., toys, activities, careers) are perceived as being “for” only girls or boys, and the implications for these assumptions. She continues to engage her students by asking, “Why does this matter? Who does this privilege? Who is silenced?”

This lesson is highlighted as an exemplary instance of mathematics education. The students go on to "fix" the word problems (in one instance completely losing the sense of the original problem).

I think it's good to re-write mathematics textbook word problems to be more inclusive. I don't think it's good to have students play out that process in their math class. Math class is for learning... math. They can learn how to perform a social justice critique in social justice class. If this is representative of the direction the state wants to move in, then I don't have a lot of optimism for the future of public education in California.
I wanted to do some larger distributed scraping jobs recently and although it was easy to get everything running on one machine (with different tools including Scrapy), I was surprised how hard it was to do at scale. The open source ones I could find was hard/impossible to get working, overly complex, badly documented etc.

The services I found to be reasonably priced for small jobs, but at scale they quickly become vastly more expensive than setting this up yourself. Especially when you need to run these jobs every month or so. Even if you have to write some code to make the open source solutions actually work.

> ...understand the web app’s requirements during the build time and reason about it before generating the final code. For example... it could pick the most appropriate architecture based on its understanding of the web app and deploy it to serverless or another type of architecture.

Wowzer! For me, this is the main benefit. I'm a big believer in low-code platforms like darklang, because the fundamental truth that bugs are a function of both SLoC and underlying infrastructure is never going to change, and one solution to that is to automate as much of it as possible.

The only problem I see is that these automations that eliminate code and abstract away the infrastructure often result in a new class of harder-to-debug or worse never-seen-before bugs. And so, building a language that "solves software engineering" may require a lot of patience and perseverance. With that in mind, how long do you plan to keep at it? How long term are you thinking you'd be doing this? I mean, you could still be working on wasp-lang whilst working full-time elsewhere... but then, that requires a different level of commitment when the business around it has failed.

> Wasp’s compiler is built in Haskell

Two questions, if I may: Why Haskell? Did you also consider OCaml (à la Rust) at some point?

Edit: I see wasp-lang is MIT licensed. Why not Apache v2 (or even MPL v2)? Especially since MIT lacks patent-grants clause.

Excited to see how wasp-lang evolves. Thanks!
I've heard of that but never tried it. I'm curious why you don't use a Ruby version manager.

That sounds very impressive, until you realize that Argentina uses slightly more energy than a single hydroelectric power station like the Itaipu Dam (103 TWh/year).

So comparing Bitcoin to Argentina really is more a testament how little electricity Argentina uses. In people's mind, a "single dam" sounds much, much less impressive than a "whole country".

Of course less math, and more Equity nonsense. In other words, some people won't learn because white knights need to help them learn. Talk about California-centric buffoonery.

We implemented Raft as a C++ library from scratch. We can probably publish that as s standalone implementation (open-source it). The main problem was the write performance and network communication overhead, even for read queries. There are some known solutions for all that. None of the Memgraph users required Raft type of guarantees, so we decided to go with a more straightforward and faster solution. It doesn't mean we won't get back to Raft in the future if required :D

Production is only relevant if you divide by the number of transactions a bill or coin can be used in. Bitcoin miners must compute at least one new block before a group of transactions can be committed to the block chain. For physical money the energy spent per transaction is relatively low, basically the energy spent opening a cash register drawer or for a large transaction the energy spent by a counting machine. I suspect that paper money is far more efficient than Bitcoin, just given the amount of power Bitcoin consumes and the tiny number of transactions processed in a given time period by the Bitcoin system (tiny compared to the number paper money/coin that occur in a given day and basically irrelevant compared to the number of electronic payments made every day).

I mean this in the nicest way, but are you seriously suggesting Apple is looking to the open-source Linux community for UI design ideas?

I followed Seesmic from the beginning. Think video chats way early. Tried repeatedly to get an account. All the VC's were using it and chatting incessantly on Twitter about it. They kept changing the app as well as the business model. Were they just following advice from the VC's?

Caught in the Silicon Valley echo chamber? They had celebrity appearances as well. Eventually they closed without ever having opened it up. Made me think they would have found out much earlier they didn't have something. Either that or they never found out the VC experts were wrong and they did have product market fit.

I have to wonder if ClubHouse is following a similar track. It's actually too hyped right now.

Brazil, Indonesia and other countries with similar levels of development are simply "late to the game" in regards to environmental destruction. Countries that developed sooner destroyed their own environments before there was scrutiny.

This is a really nice idea but considering we haven't even solved the relatively simple case of users giving permissions to apps and expecting them to behave responsibly, I'm not optimistic that we can solve the much more challenging case of importing library code.

e.g., If someone gives an app the ability to upload photos, it can silently read all photo metadata, upload all photos to a private server instead of uploading just the single photo that the user picked. This can be solved with OS level standard photo pickers but it hasn't been yet.

Same with package code. Maybe a package needs network access for stuff it genuinely needs to do. However it can (and probably will) at some point go above and beyond in the amount of data it collects. FB Mobile SDK outage is a good example of this. https://www.bugsnag.com/blog/sdks-should-not-crash-apps
Indeed it does, but generally in industry and technology one goes from inefficient prototype that serves as proof of concept to a more efficient one. Do other cryptocurrencies not improve on Bitcoin in some way? If so, why does it continue to have value despite its agreed-upon flaws? If not, why do they have any value?
You fail to understand 3 things:

1. There is no such thing as "intrinsic value" and I explained clearly why in a different reply to your comment.

2. What goes up is the value of land, not houses. If houses themselves were valuable movable homes would also increase in value. They don't. The reason why land goes up in value is that (residential) land is scarce.

3. Gold isn't a safe haven because of its track record (in fact gold is relatively volatile [0] and if you had bought gold in 1980 you'd have lost money today, adjusted to inflation), it's considered a safe haven because it's the only commodity that has a historically predictable stock to flow and can (and normally does) act as a hedge against inflation. Bitcoin does that and more.

> It's an early-stage speculative asset IMO

So was gold in its early stages as a store of value. So is any valuable company's stock in the first few months after IPO. Speculation is uncorrelated with the lack of fundamental valuable features.

At this point I'm not sure your intent is to try to understand more about Bitcoin (or economy, for that matter) but rather to force a narrative that isn't at all obvious, unlike what you're trying to imply. And I'm not saying you're wrong, rather that you're unable to corroborate your statements with data and facts.

On the contrary, the current crypto space resembles a classic speculative bubble right now, it's a perfect example of mania, and spurious justifications like this of a new paradigm which explains the crazy valuations are also classic signs of that.

Hardly anyone is using these currencies to actually perform transactions or store value because they are awful in so many ways for that (volatility, treated and taxed like an asset, unpredictable fees, slow settlement, no fraud protection etc). All the transactions, all the new accounts flooding into exchanges are there for one reason - to strike it rich in the new gold rush.

Coins intended to be a valueless joke are worth SIX BILLION DOLLARS and nobody is actually using them as a currency or a consensus mechanism or anything useful - this is pure speculation on finding a greater fool later on when you want to sell, if you're even thinking about later on, because perhaps this will never end and it's different this time.

People are buying and selling cryptocurrencies as they did beanie babies or tulips...

I don't see it truly changing how investing works. After all, the recent events are not all that different than what we saw during the original dotcom boom, where people would talk on Yahoo boards about their favorite stocks, and you'd get accidental retail pump & dumps just like we've seen recently. This is not a new pattern, it is just a new generation going through it.

What I do see changing is pricing. Robinhood proved that it is a viable business model for brokers to monetize interest on non-invested balances instead of charging per trade. The pricing will definitely go down in the future, and there may be more experimentation with other pricing models.
IIRC some Proof of Storage algorithms allow you to store actually useful data, and there shouldn't be any incentive to get fast storage, so it should have less of an effect on the average person.

Agreed. My guess is that folks tend to talk past each other on these questions, and that the important details aren't really controversial.

I found data hard to come by, but quick googling gives a carbon footprint of around 300 kg for one BTC transaction, and between 25-150 g for one letter sent (including production of the paper for letter and envelope). So BTC is around 1000 to 10000 times worse.

Would be interesting to see it sourced/researched properly, but at first glance I'd say that, yes, it is much more efficient to send a letter, even if you drive to the mail box.

Yes, reactive current is still current and any series active load (wiring) will experience that current and heat up. The reactive load itself is "imaginary".

Two reasons: (1) we try to prune subthreads when they get too massive; and (2) this one was a step in a generic direction (i.e. police in general), away from the specifics of this story.

Steps toward the generic nearly always lower discussion quality [1], because the larger the topic becomes, the harder it is to say anything new about it. Therefore the conversations tend to repeat the same points over and over, same as the last N times the topic came up (and this has been one of the most-argued, if not most burnt-out, topics in the last year). They also to get nastier as they proceed. My semi-serious theory is that the mind resorts to indignation to amuse itself in the absence of new information [2].

The generic topics are like massive planets that exert a strong pull on passing discussions—there's always a strong tendency to hop to the nearest generic orbit, because that's what our pre-existing mental associations connect to [3]. The trouble with this is that points away from curiosity, which is interested in new and specific information more than in familiar and general arguments. Curiosity wants the diffs—those are what's interesting [4]. Generally we're not aware of these competing directions in ourselves, but the effects show up unmistakeably at scale.

It's not that you or the other commenters did anything wrong! it's perfectly natural for conversation to drift in this way, and a balance of familiarity and curiosity makes for good conversation. But from a moderation perspective, it's our job to look out for the site globally, and try to dampen the sequences where each step makes sense locally but the sequence still ends up in a much less curious place.

That's a longer explanation than you probably expected, but since it's not possible to explain every individual move (it would be too much work, and also too noisy), I try to make up for it by periodically giving longer ones.

> Electricity production (not consumption) is what causes emissions

Electricity consumption (as well as other energy sources) causes plenty of heat release in the atmosphere.

With the ongoing climate catastrophe, this is a problem.
Social media use is a symptom of a bigger problem. That through automation and specialization we have run out of productive attention-occupying things to do.

Running a small business requires lots of decision-making and attention. Being a corporate drone is mind-numbing and does not. And it turns out, people have an inherent need to keep their attention busy with something. So when productive things run out, they fill their attention span with garbage.

That also means that quitting social media is only one half of the solution. The other half is to find a productive activity to take its place. And if you look deeper, you might notice that the current corporate hegemony is only sustainable when most of people's attention is drawn away from things that would create value for them.
Wait, what's your definition of variable?

Because what you're describing fits perfectly into what I would call a variable. There is a mapping from an identifier to a slot that can store a value (or reference), and that mapping is stored in a specific scope. I would call that mapping a variable.

I'm not sure exactly why you mentioned objects that have names embedded in them. Is that relevant to the definition you're using?

No, I do think he means inflation. He's talking about the block reward, the Bitcoin "minted" through mining, being larger than the fees. Currently it's 6.25 BTC minted per block and the fees only add up to between 1 and 2 BTC.

We don't really see this as inflation because of the value of Bitcoin going up, but it is a tiny tiny tax on all the people HODLING their coins, as it dilutes the value (again, by a miniscule amount).

In theory if BTC is still being used in 2150 or whenever the block reward goes to zero, all the cost of mining will be borne by those actually exchanging BTC, and the people just holding it will be free-riding, with the security of the network paid for entirely by people transacting on it. Not sure how well this will work.
If the price of energy is calculated with corresponding carbon tax included, shouldn't Bitcoin be neutral?

Yeah, I was the one trying to mislead people and shifting the goalposts.

You said “Senna constantly beat him”.

I simply pointed out that that is clearly not true.

Unlike you, I’m not biased. When I was into F1, I was a huge fan of both drivers. Senna was an amazing talent, but it’s disingenuous to suggest that he had no competition.
