zukzuk··on Bob Lee, former CTO of Square, has died after being stabbed in San Francisco
SF is a city fully controlled by a wealthy elite who buy themselves a sense of moral superiority and/or clean conscience by dabbling in "progressive causes".

If you're insinuating that progressive politics per se somehow inevitably lead to crime and urban decay, have a look north of the border.

What passes for centrist politics up here in Canada's major cities would make Berkley look like a conservative stronghold (at least in terms of economic policy... maybe we lag behind in biodynamic freegan wine co-ops). Yet Toronto and Montreal are by far the safest large cities on the continent. We absolutely have the same kinds of problems — homelessness, poverty, inequality — but our "socialist" welfare safety net and public healthcare have so far kept us out of the dystopian mess that seems to be unfolding in the US.

zukzuk··on GPT-4
That's exactly it. The bot espouses facts with the same tone of confidence regardless of whether they're true or entirely fictional.

I understand it has no sense of knowledge-of-knowledge, so (apparently) no ability to determine how confident it ought to be about what it's saying — it never qualifies with "I'm not entirely sure about this, but..."

I think this is something that needs to be worked in ASAP. It's a fundamental aspect of how people actually interact. Establishing oneself as factually reliable is fundamental for communication and social cohesion, so we're constantly hedging what we say in various ways to signify our confidence in its truthfulness. The absence of those qualifiers in otherwise human-seeming and authoritative-sounding communication is a recipe for trouble.

zukzuk··on Medicare Advantage plans use algorithms to cut off care
Keep in mind property rights can have the opposite effect too — impinging on the greater good in favour of the property rights of the few. The obvious example being NIMBYism; for example higher density construction that would benefit the city gets blocked by low-density homeowners who don't want their property negatively affected.
zukzuk··on Has Earth’s inner core stopped its strange spin?
Yes. Very much a hide your kids hide your wife situation.
zukzuk··on US can reach 100% clean power by 2035, DOE finds
More than half of France's nuclear reactors are out of commission right now, so for the foreseeable future that "70%" is more aspirational than anything.

We are obviously not going to meet all of our energy needs — especially for certain high-demand applications — from solar and wind alone, but there are some significant advantages to a decentralized power grid that the pro-nuclear folks don't seem to factor into their arguments. Assuming we can build it out, a decentralized grid ought to be much more resilient to the sort of problems France is facing right now.

zukzuk··on Crypto exchange AAX suspends withdrawals
The paranoia pertains to burying metal plates underground, preparing for a post-collapse future. As if bitcoin will be a viable currency when we're all trying to figure out food and shelter.
zukzuk··on FTX tapped into customer accounts to fund risky bets, setting up its downfall
I suppose it's easier to justify this to yourself when you know most of the people whose money you're gambling with are also driven by the same greed.

The cryptocurrency bubble was very transparently built on delusion and avarice, and everyone involved knew it. There are very few truly innocent victims here.

zukzuk··on ‘Biodegradable’ drinking straws contain PFAS
Because they are so utterly pointless. Plastic straws are a symbol of an almost entirely unnecessary use of plastic.

And that symbolism — as seems to be the case with just about anything with any semblance of symbolic value nowadays — has become politicized and polarized, which in turn has further elevated straws' symbolic value for both sides (there's a "straw man argument" pun here somewhere).

The right is obsessed with how the left is trying to control even the most trivial aspects of everyone's lives, and the left is obsessed with how the right would rather selfishly spew plastic into the environment than to give up even the most trivial conveniences.

This feels like a tension that can exist only in the Twitterverse. I really can't imagine pre-internet society actually having strong opinions about any of this.

zukzuk··on Milk alternatives produce up to 4.5x less greenhouse gas emissions as milk
So does cow milk. 7g* of added sugar in a cup of Oatly, about 8g of various sugars in a cup of milk. Oatly add the sugar to more closely simulate the flavour of milk, but it tastes about as sweet... and both are way too sweet if you ask me.

*The nutrition profile is a bit more complicated as I think they add enzymes to break down starches in the oats, so you end up with more sugar even though it's not technically "added".

zukzuk··on Le Corbusier's project Plan Voisin – a radical urban design for Paris from 1925
The parts of Paris that were most affected by Haussmann's renovation are arguably still kind of awful.

The Champs-Élysées for example is a horrible place to actually spend time in, and is currently undergoing major redevelopment to make it a bit more livable.

zukzuk··on An Open Letter from the CEO of Puppet: Puppet and Perforce
Why would it not being Ruby-based be a plus? Go is a big improvement over Ruby in some use cases, like where performance or concurrency is important, but this is not one of those cases.
zukzuk··on Canada to ban foreigners from buying homes
Everyone's got their pet theory on what's behind Canada's housing crisis. In reality it's probably a combination of different factors.

The NIMBY theory is probably part of it, but definitely not the full story. For one, Toronto and Vancouver's population density is on par with major european cities (Toronto is about the same as Berlin, and Vancouver same as London). Arguably most european cities have similar affordability problems, but if NIMBYism is an issue, it's not particular to Canadian cities.

My pet theory is it all comes down to money supply. All that money generated out of nothing through quantitative easing over the last decade+ had to end up somewhere, and it's settled in real estate and equities. If that's the case, then the end of QE and "balance sheet pruning" is going to put a stop to this... and likely pop a giant bubble in the process. That's a scary prospect for countries like Canada and New Zealand, where RE has played such a huge part in inflating wealth.

zukzuk··on Difftastic: A diff that understands syntax
I wrote a masters thesis about the more general problem here (https://tspace.library.utoronto.ca/bitstream/1807/65616/11/Z...).

The tl;dr is that there's an almost infinite number of ways to atomize/conceptualize code into meaningful "units" (to "register" it, in my supervisor's words), and the most appropriate way to do that is largely perspectival — it depends on what you care about after the fact, and there is no single maximal way to do it up front.

zukzuk··on Italian scientists hacked pizza physics to make dough without yeast
But that's like half the fun of being orthodox!
zukzuk··on The Unbundling of Airflow
Everyone's context is different, but I've found the exact opposite to be true. Airflow is simple and dumb enough that it can be easily understood and managed by a small team, but it's also flexible and powerful enough that we can't come up with a good enough reason to switch to anything else.*

*We are, however, becoming more and more reliant on dbt, and the article makes a good point about Airflow providing no visibility for what's going on in a dbt node. So we're ending up with an increasingly simpler Airflow dag, with most of the complexity hidden inside a single dbt node.

zukzuk··on Radical Polish books to add to your reading list
Flights is a great piece of writing though. Definitely not for the Lem crowd, but I guess there are weirdos like myself who like both.
zukzuk··on Using PostgreSQL as a Data Warehouse
That first point is exactly what dbt (https://www.getdbt.com/) does. It's an amazing tool, with extremely well thought out developer ergonomics.
zukzuk··on Apple Reports Second Quarter Results
Designers design for usability. The idea that design is about "making things pretty" is on par with the idea that software development is about making computers crunch numbers.
zukzuk··on Making sense of what’s going on in the housing market
Up here in Canada, there is absolutely no doubt that we're in a bubble. By every measure we're in trouble... consumer debt levels, income-to-price and price-to-rent ratios... This infographic has been making the rounds and pretty much sums things up: https://twitter.com/i/status/1377353707478601729

Even the apologists who previously tried to to explain this in terms urbanization, desirability, immigration, etc have capitulated.

It remains to be seen whether we're just an odd case (along with maybe NZ and a few others), or a canary in the coal mine for our neighbours to the south, but the situation here at this point is virtually guaranteed to end badly for everyone involved.

zukzuk··on The Unparalleled Genius of John von Neumann (2019)
By most accounts Gödel lived an anxious, unhappy life. He died, basically, from paranoia.

Not to say that von Neumann lived a happy life — he sounds like a bit of an asshole — but I wonder whether Gödel would have traded his achievements for less isolation and a less tortured existence?

zukzuk··on In spite of an increase in Internet speed, webpage speeds have not improved
... which is just a special case of https://en.wikipedia.org/wiki/Jevons_paradox
zukzuk··on Introduction to Apache Airflow
Airflow is great, right up to the point where you try to feed date/time-based arguments to your operators (a crucial bit of functionality not covered in the linked article). The built-in API for that is a random assortment of odd macros and poorly designed python snippets, with scoping that never quite makes sense, and patchy and sometimes misleading documentation.

zukzuk··on Samsung TVs May Upload Screenshots for Automatic Content Recognition
https://ironcast.tv maybe? I want to buy a new TV in the next few weeks and I'm really tempted, but worried about this being a Kickstarter project and the display quality not being up to par.
zukzuk··on Share Now, formerly Car2Go, is leaving North America
In Toronto they got in a spat with the city over street parking and pulled out about a year ago. Really unfortunate as it was a great service, and seemed successful in terms of adoption. There's a new one in its place called Commune Auto, but lacks the visibility, as those little Car2Go smart cars with their branding really stood out.
zukzuk··on Cargill: The Worst Company in the World
Not exactly a special set of glasses, but probably as close as you're going to get right now: https://www.buycott.com/

That said, the idea that you can enact change by making "good consumer choices" is probably one of neo-liberalisms greatest, most insidious triumphs. It subverts democratic ideals to make us feel like we have power, while diverting our energy away from pushing for the kinds of systemic changes necessary for meaningful impact on big problem (e.g. putting the responsibility for reduction of plastic pollution on consumers, rather than on manufacturers via legislation).

zukzuk··on Plastics recycling with microbes and worms is further away than we think (2018)
https://www.penguinrandomhouse.com/books/539747/winners-take...

Great book on this very topic!

zukzuk··on Obsidian: A safer blockchain programming language
Tezos, which is itself written in OCaml (what originally attracted me to the platform), already has a relatively well design language for writing contracts called Michelson (https://tezos.gitlab.io/master/whitedoc/michelson.html). I say "relatively", compared to the dumpster fire that is Solidity...
zukzuk··on When Boris Yeltsin Went Grocery Shopping in Clear Lake
Canada is one of the few (the only?) countries where it is specifically illegal to offer privately a service that is covered by public insurance. For the most part, there is no option to opt in for private care as an alternative.
zukzuk··on Choosing Ruby on Rails for web development project in 2019
Or not! Here in Toronto we've had a req open for a senior Ruby dev since like last October. We're seriously debating switching over to something else for no reason other than lack of available Ruby talent. Relatively view new devs are picking up Ruby nowadays.
