I loved discovering that rust has O(n) guardrails on regex! The so-called features that break that constraint are anti-features.

Over the last two weeks I wrote a dialog aware english sentence splitter using Claude code to write rust. The compile error when it stuck lookarounds in one of the regex’s was super useful to me.


Is there firmware to turn the Bose Alexa into just a Bluetooth speaker? I see there is a bose-dfu utility on github, but its list of supported devices is short (because the person who made it didn’t have other devices).

The bose speaker is sufficiently nice i might try to salvage it.


I really did like that kitchen timer. This seems like it would have been pretty good.

However. My wife is super pissed at Bezos. She unplugged all our echos. She has me researching to try decide between a Roku or Apple tv to replace the fire tv.

The amazon card went from 90% of our non-mortgage spending to 10% and dropping.

I honestly didn’t believe it would ever happen but I think we are probably going to drop Prime soon.

I’m still thankful for the Expanse, that show was great.


Pointed a friend toward this. He thought it was cool, but said he’d never wear a Cray wristwatch because he heard they run fast.


there’s a quote at the end, saying this establishes a fundamental connection between two objects which are central to computer science.

The quote leaves those two objects unnamed. Are they supposed to be “graphs” and “groups”?


> It proves, for instance, that certain types of graphs that have to do with groups, called Cayley graphs, must have Hamiltonian cycles

Yes, graphs and groups.



Operation Legend

Federal officials stage a major law enforcement operation in a city with zero coordination with the mayor of that city, who instead learns about it from twitter.

Operation Diligent Valor

A top U.S. Homeland Security official on Monday defended the federal crackdown on protests in Portland, including the use of unmarked cars and unidentified officers in camouflage gear and said the practice will spread to other cities as needed.

ACLU lawsuit: https://www.aclu.org/press-releases/aclu-sues-federal-agents...

Restraining order issued against attacking journalists:

U.S. District Judge Michael Simon today blocked federal agents in Portland from dispersing, arresting, threatening to arrest, or targeting force against journalists or legal observers at protests. The court’s order, which comes in response to a lawsuit filed by the American Civil Liberties Union of Oregon, adds the Department of Homeland Security and U.S. Marshals Service to an existing injunction barring Portland police from arresting or attacking journalists and legal observers at Portland protests.

Oregon just had their attempt to remove federal police thrown out.[1]

In a 14-page order, U.S. District Judge Michael W. Mosman ruled that the state lacked legal standing to bring the suit and had “presented no evidence that these allegedly illegal seizures are a widespread practice.”

How does that explain the quantum eraser experiment?

a photon that has been "marked" and then "unmarked" will interfere with itself and produce the fringes characteristic of Young's experiment.

Did you mean to reply https://news.ycombinator.com/item?id=23221433? I don't see how QEE is incompatible with the notion that measuring something necessitates interacting with it. Photons are usually measured by absorbing them and turning into electricity.


It is fair to say this group is the reason we didn’t have an even worse outbreak, and it was solely due to defying the Federal officials:

“By Feb. 25, Dr. Chu and her colleagues could not bear to wait any longer. They began performing coronavirus tests, without government approval.

What came back confirmed their worst fear. They quickly had a positive test from a local teenager with no recent travel history. The coronavirus had already established itself on American soil without anybody realizing it.”


This story strikes me as off. It runs counter to every other aspect of the virus we focus on. Specifically, if it was already spreading in schools, then why don't we see scores of critical kids and parents? With how contagious this is, I find it fairly unconvincing that it was just that student.

Combined with symptoms taking about a week to present, this was in community spread for a while. Yet, here in WA, the deaths figure is still 92% over sixty years old. I don't know the percent from long term care facilities. (I would love that stat.)

Then the question is at what point did it break into long term care facilities? And could we have done something to strengthen their protection?

With a further question of what, exactly, causes it to go severe.


Seems like the results in this blog post would be of interest.

Not so much in avoiding the halting problem while allowing complexity, but instead using it and actual runnable Turing machines to create ridiculously cool cases of unprovable truths.

For example a running Turing machine that only halts if it contradicts set theory.


My understanding is, unlike any other government agency or business, the USPS is required by law to fully fund 50 years of pensions. If that requirement were removed, it would be fine.


Businesses are required to fund their pension obligations.

In any case USPS hasn't actually fully funded their pensions since the recession.


They’re required to PRE-fund the pensions which private businesses are not required to do


Of course private businesses are required to pre-fund their pensions (with some exceptions like religious organizations).

It's a requirement under the Employee Retirement Income Security Act of 1974.

I totally agree with you, but why is it a problem right now? Parcel volumes are at dizzying heights.


According to the article revenue from advertising (junk mail) is down 40% while local businesses are mostly closed.


This is an anecdote not data, but I've heard several USPS delivery folks mention that a lot of long-tenured drivers decided to take vacation and sick time when the lockdown started ramping up. This has caused other drivers to pick up the slack so there may be a lot of overtime getting paid out.


This doesn't wash. If advertising is down 40% and parcel services are up 150%, that's a substantial revenue increase overall.

https://about.usps.com/who-we-are/financials/annual-reports/...

I can't get the numbers to add up here. Even with letters down, advertising down then their revenue should either be flat or have a slight increase based on my guesstimate for their increase in parcel business.
