Specifically, DOGE
pulisse··on Whistleblower claims ex-DOGE member says he took Social Security data to new job
"He told another colleague ... that he expected to receive a presidential pardon if his actions were deemed to be illegal."
pulisse··on In New York City, congestion pricing leads to marked drop in pollution
Very few poor people drive into lower Manhattan. And people whose work requires them to drive in that area (delivery drivers, plumbers, etc.) come out ahead. One of the first NYT stories after congestion pricing was rolled out had multiple quotes from tradesmen reporting that they're saving an hour or more a day and prefer the new system.
pulisse··on In New York City, congestion pricing leads to marked drop in pollution
The point of congestion pricing is to let market mechanisms determine where the optimum is.

Sub-headline: "Pardon follows months of efforts by Changpeng Zhao to boost the Trump crypto company"
pulisse··on Klein Bottle Amazon Brand Hijacking (2021)
> A lot of books, even small scale ones, are also fake and very low quality.

My sister works in manga and anime publishing and this is an existential threat to her company. Some of the issues they're grappling with:

1. For some of their titles, the genuine item doesn't even appear among search results on Amazon—only the counterfeits do.

2. The quality issues with the counterfeits can result in losing all future business from a customer. For example, download codes will be missing or non-functional. Irrational as it is, customers blame the publisher when this happens and stop buying further titles from them.

3. Amazon seems to be using some slapdash ML to determine how many of each title to order. They'll purchase 10k of vols. 5 and 7 of a series and only 1k of vol. 6. Guess how many of that 10k of vol. 7 end up selling when that happens?

Amazon is, needless to say, non-responsive to their concerns.

> I would expect them to be shielded from executive pressure.

In the past month the SEC has stopped most enforcement actions involving crypto.

pulisse··on Italian streets that don't exist on any map (2022)
Italy's not unique in that respect, in Europe at least. You can't do much in Germany without a Meldebescheingung.
pulisse··on Apple's 'incredibly private' Safari is not so private in Europe
Not "any user action". The user has to click the link. The fact that a link can be styled to look like anything isn't very damning.
pulisse··on Apple's 'incredibly private' Safari is not so private in Europe
I'm not seeing what the "catastrophic" issue is. A site can include a link to install an app from a third-party marketplace and, when the user affirmatively acts to proceed with the install, that marketplace can see which site the install request came from.

That's it?

pulisse··on Serious flaws in SQL (1990)
> SQL is mostly used as a compiler target these days, with users using higher level languages

This is not remotely true of analysts and data engineers, who probably write most of the world's SQL.

pulisse··on New Foundations is consistent – a difficult mathematical proof proved using Lean
The system isn't being used to prove its own consistency. The consistency is proved in a different, stronger system.
pulisse··on Apple alerts users in 92 nations to mercenary spyware attacks
The conversation here is focussing on industrial espionage, but that's only one use case for this kind of active measure. An association with an opposition political party could easily get one on a surveillance list.
pulisse··on 2023 ACM Turing Prize awarded to Avi Wigderson
> BPP is the complexity class for decision problems that a randomized algorithm can solve in polynomial time, in the sense that on every input (worst-case), the algorithm is right with at least 2/3 probability (over its own randomness).

What's the theoretical significance of the 2/3 threshold?

pulisse··on Topologists tackle the trouble with poll placement
Voting in Oregon has been exclusively by mail since 2000 without any such abuse materializing.
pulisse··on Topologists tackle the trouble with poll placement
If a jurisdiction is reducing the number of election day polling places in an area, they're also going to reduce opportunities to vote in other ways. An egregious example is Houston, where there is now one (1) place to drop off early ballots in a county of 4 million people.
pulisse··on The complete story of Gödel incompleteness
TFA uses sloppy phrasing, but it's correct. The claim is not that earlier logicians such as Frege viewed logical concepts as meaningless. It's that, before Tarski and Gödel, no one clearly distinguished syntax and semantics, and so earlier logicians lacked the conceptual resources to describe the difference between truth and provability, let alone investigate their relationship. (Frege only ever considers a single semantics for any formal system.)
pulisse··on "Dune" and the delicate art of making fictional languages
The book presented only a few phrases from within-universe languages. The movie includes non-trivial amounts of dialogue in those languages, which someone had to write. How they did so could be interesting, and an article about that isn't any more suspicious than one about the movie's vfx or any other aspect of the creative process.
pulisse··on The seventh most popular easily understood unsolved problem on MathOverflow
There's a great Mathoverflow thread collecting examples of this sort of phenomenon (called "eventual counterexamples" in the thread), together with some interesting analysis (see Joel Hamkins' answer): https://mathoverflow.net/questions/15444/examples-of-eventua...

> Serializable and snapshot are indistinguishable for read-only transactions, no?

No. See "A read-only transaction anomaly under snapshot isolation" [1].

pulisse··on Apple patents suggest future AirPods could monitor biosignals and brain activity
They'll charge more to serve you ads when you're in a more receptive state of mind, but the ads you're served won't necessarily be better.
pulisse··on We are retroactively dropping the iPhone’s repairability score
> It seems pretty easy to implement the "unpair" functionality you ask for.

Implementing any functionality over two billion devices is non-trivial, especially when it requires aspects of transactional behavior (as this would).
