Off topic, but this looks like a well organised, independent learning network. Where can I find others, on serious topics, that are independent of platforms or publishers? Is there an 'awesome' list of topic-based reading groups (not book clubs) for interested learners?
In the most literal sense of the word. 1 KW at 100 meters on a directional antenna like that will happily light up neon tubes. The field is going to be a few hundred V/meter.
Thought experiment - Bitcoin supports fewer transactions than are needed for a mid-sized town, yet uses more power than most small countries.

The upper limit of the amount of power a country’s financial system could use is the power footprint of that country. Likely the real usage is a small percentage of that, but that’s the upper limit.

Now, given Bitcoin uses more power than countries of millions, but supports the transaction load of a few hundred thousand, do you think it is the slightest bit possible your comparison would come out favourable to Bitcoin?
Thank you for sharing this! We played this on Commodore 64s in elementary school and I've haven't seen or heard of it since. (I've looked too!)
Perhaps for a bit of additional explanation, a guitar pickup is a variable reluctance sensor. It's a coil wrapped around a magnet. The magnet sympathetically magnetizes the string, and then the vibrating magnetized string induces a voltage on the coil. The strings have to be made of a magnetic material such as steel, nickel, or one of the magnetic stainless alloys.

Beyond what was mentioned about single and dual coil, each pickup has a unique resistance and inductance, which at first glance might affect the frequency response of the typically crude circuit in the guitar. And the magnetic field may also produce some damping of the string motion. Those are some things that might affect tone quality.
App developers do this in their apps too when asking to rate the app in the App Store. They first show you a fake popup asking if you are enjoying the app OR want to send feedback. They will only show you the real iOS popup for reviewing the app if you tap "Yes" to the enjoying app.
The Bitcoin CO₂ is some made up measure anyway, mining interest for a year isn't really attributable to the market cap of Bitcoin (they feed back on each other and so on, but there's no direct relationship).
Because we guitarists enjoy the wild goose chase that is the never-ending quest for ultimate tone, and thus need to try as many pickups as possible.

But on a more serious note - it's because woods sound very different, and pickups will sound very different depending on what guitar they're in. It's a pain to take the strings off, de-solder a pickup, solder in a new pickup, and put on the strings - only to discover that the pickup doesn't sound any good. Being able to swap them out in mater of seconds is an all-around improvement.
IIRC most of the water used to produce meat goes into producing the animal feed.
The pattern tries to avoid an outcome desired by the user: permanently revoking consent for some permission. Only asking when you are confident the answer is Yes goes against the intent of the platform functionality, and I’d argue that’s a major dark pattern.

Similar to how apps used to ask “how do you like app?” And then only prompt to review the app if you responded favorably. Goes entirely against the app store’s intent to uniformly sample users, and I’m glad Apple at least has cracked down on this practice.

Just honestly make a product and stop trying to fool the user!
if recall yeah there probably will be. linear regression minimises the vertical distance of a point to the regression line whereas PCA minimises the orthogonal distance of the point to the line.
Oh well it must be the case then? Microwaves resonate with water molecules. If the surface is moist it will heat first. If not... Well it won't!

My experience with wage workers that are struggling to make ends meet is different. They spend a lot of time looking for better jobs and side gigs. Like, it is their primary focus.
Actually the costs to mine a block on the blockchain are the same, no matter if somebody buys a Bitcoin or not. At most you could argue that driving up the price gives miners an incentive to mine more.
you're right, I reworded that incorrectly - now updated, thanks for spotting it!
UML failed because there was no way to track changes; no way to 'diff' two versions of a design. And no way to display the 'diff' effectively. Tracking source code changes is the basis of Software Engineering. Git is one major example. What changed, when, who, and why.

With a graphical language, the 'diff' has to be able to distinguish between a visual change like moving objects around and semantic change of adding / deleting objects or links. It must know the difference between 'what it looks like' and 'what it means'.
> It also demonstrates a growing chasm between attitudes in the United States and Europe about data governance

Yes, in Europe we got GDPR. In the USA you got a bunch of jokes and jokers trading your data for peanutes.

The disregards towards 'anything' is BAU.. "move fast, break things". I feel that in the USA many companies are in a money-grab. "We will fix it later", and the later becomes never. Because once you created 100 problems, you only 'invest' to fix the 'top 5' and only because an auditor/CISO told you so.
No, I'm not comparing to "covid stops spreading", but I'm also not assuming (as you seem to be) "everyone will eventually get it in the way whoever got it so far got it".

> Each scenario has associated cost.

There are other scenarios, e.g. https://www.ox.ac.uk/news/2021-02-09-common-asthma-treatment... shows a cheap widely available steroid inhaler has comparable efficiency to vaccines in the KPIs studied by the Pfizer trial. I'm not saying it should be used instead of a vaccine; but it's also not true that your list is close to exhaustive. We keep finding out new stuff. In the first 2-3 months, the intubation+ventilation regime was counterproductive; it took a while to realize, but now we know that. We also know (e.g. from Florida and Texas) that the NPI are much less effective than they were assumed to be.

> Each and every vaccine up to now is orders of magnitude safer than Covid for the vast majority of people (YMMV!).

That's ... not been shown. The Israeli study I linked to above (a report of it) says this assertion might be wrong for Pfizer for the sizable group of 16-30 ; The British think that's not true for AZ under age 30 ; many countries in the EU think that's not true for AZ under the age of 50 ; Norway thinks that's not true for frail elderly.

And basically, we only have short term safety data (pfizer: less than a year for 20K people, less than 6 months for the rest), so even if it is true that "every one will eventually get it", it does NOT follow that it makes sense to vaccinate everyone right now -- if it takes 20 years until "everyone eventually gets it", and severe side effects appear 2 years later, then, no, it doesn't make sense.

I linked a BMJ+Science article that showed for a similarly EUAd vaccine, "Pandemrix" in 2009 that it took over a year to figure out that it was causing narcolepsy and worse than the flu it was supposed to stop. It's not just a theoretic possibility - it happened in a very similar setting just 11 years ago, and the causes are NOT perfectly understood to the point that you can guarantee it won't happen again.

> many are conjectured to be due to the 'SARS-Cov-2 ingredients' (e.g. myocarditis). Heuristically speaking you can choose between Covid or a very very very mild version of Covid.

You could be right, but that's not at all clear. This paper from Nature Immunology https://www.nature.com/articles/s41590-020-00808-x.pdf shows that 80% of unexposed people have a T-cell response to SARS-Cov-2 - that is, they have cross-immunity.

It could be that for those 80%, that response would be enough to stop the virus before it can get systemic traction, whereas the vaccine is essentially guaranteed to generate systemic effect. I asked an immunologist, who said he doesn't know the answer and does not believe anyone does without measuring.
Where has it been suggested that this is the best solution for "the average SQLite user", instead of a tool you can use if it fits your requirements? To take your 10MB number, the article starts by mentioning you can probably just download the entire thing if you aren't above that exact same number.
Thank you! This is something that has been annoying the hell out of me on instagram using desktop Firefox.

Every time I login it prompts to show notifications; I always decline so it shows it again next time I log in. This time I accepted, but blocked it from within firefox.

I get it's not a dark pattern because it's clear it's not the browser asking, but still it's very annoying.
Do most static site hosters support range requests?
How much harder is it for someone operating in bad faith to turn the lack of politeness and respect to their advantage? My personal experience would suggest it's even easier.

[dang's pretty good about enforcing politeness and respect, so I won't try to present any examples. :-)]
More importantly, where do I get a breakfast taco in California?

The fact that my pre-Covid early morning business trips from Austin to San Diego used to have me delivering a boatload of breakfast tacos from the Austin airport shows that there is an untapped market.
Not bank transfers, but https://digiconomist.net/bitcoin-energy-consumption says

> 778,988 - The number of VISA transactions that could be powered by the energy consumed for a single Bitcoin transaction on average (1157.81 kWh).

Obviously bank transactions would also come out way ahead, those are essentially a DB update built on trust and for speed, whereas proof-of-work is severely inefficient by design.
I highly recommend vermicomposting which involves hundreds of even thousands of little worms. I have a HungryBin and don't even need a green bin anymore, at least not for kitchen waste. What you get is compost which is great for gardening and worm tea which is great fertilizer.
That's often true when you're talking about a single project with a clearly delineated end state, such as, "Build a responsive website for my coffee shop that works in all major desktop and mobile browsers."

But it's generally not true when you're talking about advances in technology and market dynamics where there are multiple inflection points. If I told you that the products Apple is planning to build over the next 3 years are going to be harder to build than anything it's built in the previous 45, simply because the last 5% of anything is the hardest, you'd probably say, "That's not what I mean!"

I think it's pretty obvious that building autonomous vehicles that can understand human driving behavior without direct communication is harder than building autonomous vehicles that only have to worry about other autonomous vehicles, with which they can communicate in data-rich ways. The fact that the former needs to happen before the latter because of market dynamics doesn't change the fact that it's a harder technological problem.
"...with regards to NFTs we will see PoW take precedence since it reduces fraud."

This is a massive assumption, and likely wrong. From Ethereum to Cardano and beyond, NFT's are almost exclusively being created on smart contract platforms that either already utilize PoS or are transitioning to it quickly. So the idea that PoW will take precedent in the NFT space.. how?

Regarding fraud, is that to suggest PoS is not secure? Also a massive assumption and likely wrong.
The higher the price BTC go, the more miners will mine to get it near break even. Imagine 600k price where some pumpers are targeting, you are looking at potentially 10x the energy used to mine blocks. Is that a correct characterization of the problem at hand?
This articles makes absolutely no sense. It uses market capitalisation of Apple and bitcoin to compare the CO2 emissions of an iPhone and a bitcoin transaction which is clearly nonsense. You could calculate the rough CO2 emissions of a 1 BTC transaction by dividing annual estimated CO2 emissions by bitcoin miners (35 million tonnes) by the number of annual transactions (100 million) which equates to about 350kg of CO2.

An iPhone on the other hand produces around 100kg of CO2 to manufacture according to https://www.compareandrecycle.co.uk/blog/iphone-lifecycle-wh...

So in summary it's actually only 3 to 4 times.
> I would have guessed that the person who greeted me, showed me where to sit, and asked if I needed anything before leaving was a receptionist regardless of gender. That seems like an unfair strike/test.

I had the exact same thought and then immediately realized it was bullshit. If it was a man I think I would question their role and I think that’s true of most people. It’s hard to say after the fact.

Some people don’t have these biases but most people who think they don’t are just full of shit.
I hope the attempt worked. I was trying to find how the new title related to the original one and was skimming the article in the process. It didn't seem that, well...peaceful?
Nothing to add to the conversation, just wanted to say I absolutely adore this. Years ago I used to think it'd be nice if search engines simply exposed all their shards to clients and let clients do all the results merging and suchlike. Of course that's probably a terrible idea in practice for performance, but this library is definitely implementing the spirit in a very practical way!

It also reminded me of a vague inverse of this hack. In old versions of Qemu (possibly it is still implemented, but I have vague memories it got ripped out), you could point Qemu at a directory on disk and it'd produce an emulated floopy disk drive with a virtual FAT12 image containing the directory contents. AFAIK it didn't keep the actual data in memory, I guess all it needed was file sizes to know how to build a virtual memory mapping that contained the filesystem metadata + proxied reads from the underlying files for data sectors. I look forward to seeing your implementation of this concept in a virtualized SQLite file <-> GraphQL proxy ;)

edit: insane, it still exists and apparently supports write mode?! https://en.wikibooks.org/wiki/QEMU/Devices/Storage#Virtual_F...
Men, if you want to know how to help prevent this kind of nonsense, pro tip:

> he went on to say that Dick is a bully, and he’s personally wanted to punch Dick for years

This executive leader tolerated Dick for years, and then instead of getting Dick fired for gross and inappropriate touching, he celebrated a harassed woman on having to physically defend her person inside the workplace.

So, men, your mission, should you choose to accept it: Stop tolerating bad men in your professional and personal lives. Call them out. Report them to HR. Tell them their behavior makes you uncomfortable. Stop hanging out with them. Accept the penalty to networking and move on to better people.

Otherwise you’re just the enabler that makes it possible for bad men to hurt others without consequences.

(Obviously, don’t tolerate bad women either, but from a statistical standpoint, focusing on the men-enabling-men problem will have the widest societal impact for women.)
Slack is being used as a substitute for all kinds of communication patterns where it shouldn't be and people tend to be assholes about it.

For example, mandatory-participation announcement channels that don't actually require any action on the part of the receiver. They're used for every corner of the company to self-congratulate and should be emails instead of notifications.

For anyone who can make these decisions in their own comapnies, if a channel's messages:

- do not require immediate attention, and
- do not require an action,

for the love of god, do not make it a mandatory-participation channel.
Linear regression uses a measure of an "error" for every data point. Visually, the error is the vertical difference between a data point and the line/plane of linear regression. In contrast, PCA measures the distance from the data point along the line perpendicular to the PCA axis. The PCA distance is also known as a "projection".

There is something known as orthogonal regression (total least squares) which uses the same measure as PCA. Unfortunately it doesn't work well across incompatible variables.
Right, but other browsers have better behaviors to some people. For example, Safari's behavior of opening links as new tabs in the foreground is very annoying to me.
This is hate speech.
> any thread unifying these things

Yes, this is the critical question. And I think the authors of this "reading group" answer that in this really smooth introduction to sequent calculus:

https://www.youtube.com/watch?v=xLRUofFSq5Y

Recommended watching!

The summary (explained in the video) is that these three areas: differential programming, probabilistic programming, and logic programming are all just programming language semantics that are more specifically "languages for calculating" and thus "calculi" languages.

These three areas are also all linked to historical and current AI research. And I think AI research is the primary motivation (another underlying thread) for this collection.
I’m trying to understand this. The value of the “emission” would fluctuate with the value of the coin? But the wording is weird. How is “buying a Bitcoin” generating 195x co2 compared to x? The mining of Bitcoin has already happened. That emission is over for that Bitcoin after it has been mined. And tying either Bitcoin emission values to capital values. Or iphone emission values to Apples capital value also doesn’t seem very intuitive. What’s the point?

Using solar energy "pollutes" also the environment.

1. Less energy is available for other demands. They have to be filled up with other energy sources. (Assuming, that they do not use their own panels for mining.)

2. Producing solar panels produces CO2

It’s a trick to try to take a yes / no choice and sneakily turn it into a “yes / ask me again later” choice. Silicon Valley in general seems to have a huge problem with the idea of user consent and permanently revoking consent.

Discord does this as well. If they detect a mobile user agent they disable the button to hide the member list which makes group chats unusable. If you just change your user agent the button re-appears and you don't even need the app unless your browser doesn't handle voice and you need that.
Apple operates at pretty comfortable profit margins. At one time it was the most profitable company in the world. I'm not sure this comparison is fair - Apple is famous for creating highly valuable outputs with relatively minimal inputs.

This comparison is just for fun, but there seems to be some buzz about Bitcoin not being environmentally friendly I don't know why people are all grumpy about Bitcoin, there are a lot of things that we waste energy on.

Maybe if the world governments were a bit more responsible with their currencies then there wouldn't be a need for Bitcoin. It was a direct response to the outrageous actions taken after the '07 crisis.
I covered all of that in a previous article and many more since. https://apisyouwonthate.com/blog/graphql-vs-rest-caching

Basically, trimming a few bits off of a request is not overall quicker than helping clients not need to make as many requests by designing an API well enough that resources can live on their own and declare their own cachability.

Designing your API resources so that primary data can be fetched and displayed before you start mucking around with secondary and tertiary data is also important. When you talk about being slower for the user, is it actually slower for a real human doing real things on the site. For example, I've seen GraphQL queries loading a social media feed, and list of friends for a little box on the side which didnt matter, and a list of comments on posts that havent even been expanded yet so now user could see it, and querying to see if there is any availability in conference rooms even if theyve not shown any interest in booking a conference room. The clients wanted to avoid making multiple calls because ooooh thats bad, but the whole page was just a blank white screen until all that pointless data came back. Querying all of those resources seperately over the same HTTP/2 connection and letting the UI progressively enhance would absolutely be quicker than mushing it all into a single giant HTTP request but that's what everyone does. All the time. It's insane.

Again, Fastly wrote about all of this very well. This article is one in a series which doesn't stand as well on its own.

I was a bit disappointed in the article given the headline. The analytical methodology used here is a bit odd to me, and there was no explanation as to why this methodology was used.

I still don’t know how much incremental CO2 is emitted from buying a Bitcoin or an iPhone after reading it. All I see is a weird CO2 divided by market cap calculation...

Does anyone else have good data on the incremental CO2 emissions from either of these?

Yes, and most animal feed is human inedible stuff like grass and corn stalks. The water used to produce these is rain water that would fall and drain or evaporate from there either way.
It's not that power intensive to do a BTC transaction (although the requirement for every full node to duplicate the work kinda limits its relative efficiency). What drives up the power usage is the way miners compete for new bitcoins. 25 new bitcoins are minted every ~10 minutes, and 1 BTC is worth 56,378.78 USD right now, so the miners can collectively spend up $1.4 million (in electricity, hardware depreciation, etc) every ten minutes and still break even.
I'm so thankful for the Reddit redesign, I had a serious problem spending way too much time on that site. Now it's almost completely unusable.
For me personally, my wife is an immigrant so a paper trail is important. Before that though, I think there was a time where companies didn't email out the records, so they'd keep the records for a year or two and then you would lose access to them, but the IRS wants several years if you get audited. Nowadays though, if it wasn't for my personal situation then I probably would have switched to saving off a digital record.
