When f is 60Hz, it makes for some nice round numbers, and easier for mental calculations.

ω=2πf

At 60Hz, ω is 376.99... very near to the integer 377.

Also, Z₀, impedance of free space is not far off at 376.73... Ω

Normal LED lightbulbs shouldn't flicker on standard 60Hz circuits. Do you have a dimmer switch or smart switch in the circuit? I've noticed these cause flickering that's visible on camera or out of the side of my eyes.
That's exactly what I'm also looking for. I've been looking for a house in both Canada and the U.S. and for Canada there are some house search websites that show demographic census data for each neighborhood. For the U.S. I haven't seen anything comparable. I don't even know if this type of demographic data at the necessary granularity would be available publicly?
Thank you for the feedback. Yes, the precedence is a question for me. Maybe I will change this.

If I shift it behind concatenation there could be another problem. E.g. with non-associative : should be illegal. And I am not sure how to treat this:

cat:dog:mouse

In the current version I inject the epsilon (empty string). It looks natural E.g. to remove every second letter I could run '..:' which is technically '.(.:eps)':

echo 'abcde' | ./trre '..:'

result: 'ace'

actually ':' association could have a meaning as a composition of regular relations; but I found it too complicated for now.

In my experience, age of homes in the neighborhood approximately equals age of kids in the neighborhood, +- a few years. And that makes sense if you think of who is typically buying houses en masse as a group - new families.
Now, I don't live somewhere like SF of NY where people cycle in and out, more cities of various sizes in the midwest and south.

My first house was built in the 40's. A few original owners existed, along with second owners. I noticed I guess people don't tend to move often. There were hardly any kids in the neighborhood.

Next house was built in 2009(this would have been 2018ish), and the neighborhood was packed full of kids.

Next house was built in the 80s. A lot of original owners, again, few kids.

Next house was built in 2012, this would have been 2021 - tons of kids

Next house built in mid 90s. This was 2022. Almost everyone in the neighborhood was the original owner, very few kids.

So, if my theory holds, if you want to find a neighborhood with a lot of kids, buy a midrange house in a ~5 year old neighborhood.

(and yes, I realize I've moved a lot).
What H3 do I belong to if my house is split between three different ones, pretty much equally? Any/all of them?

Financially liquid companies locked into feeding AWS (with their 50%-ish profit margin) should buy Nvidia/TSMC/ASML/(AMD) stock to get some of their money back?

The other one isn't even voted in yet, hasn't done anything yet, and the current one already wants the data, that they shouldn't get.

The current ones are already abusing their power, and the other one might hypothetically do something, if and when and if at all.

This is like Alice making it legal and then punching you in the face and instead of you "punching back", you say "this is fine, but Bob is bad, because if he gets voted in, he'll punch harder".
In the UK, a big sack of feed for chickens costs around £12, and that will feed 15 chickens for a week (roughly). So I could be wasting 80p/week per unproductive chicken.

> Taxi Medallion laws were also a Reputation Engine that was publicly queryable, subject to FOIA laws and generally had easy to search public databases for them, with detailed notes.

You just landed at the airport and need a cab. You fax your FOIA requests for each of the hundred cab companies in the area, which they're required to provide within 20 business days. Your return flight is in 3 days and it would be nice to leave the airport before then.

> Sure Uber/Lyft boil that into a "friendly" 5-star UI, but do you have any idea what data contributed to that star rating? Do you always trust the algorithms that compute them from a bucket of metrics you can't directly request?

So compete with them instead of banning them. Fund an open source ride hailing app with open data. Don't require anyone to use it. If it's better, they will. If it's not better, why should they be forced to?
Why would a private US company be ordered to provide anything to researchers just because others do it? What's the logic behind this?
The funny thing is that anyone pointing out authoritarianism will get downvoted with a whole bunch of partisan arguments or left/right false dichotomies.

Here we are, though, at the point where the government overreach for these "beacons of democracy" such as US and UK do this often and by design and we're all supposed to pretend "thing are fine, trust us". Next they'll push some other overreach using children, terrorism, drugs or some other usual excuse and people will defend it pretending the government has good intentions and largely works for the people.

The only way to send signal to commercial entities is economic. This is signal, and another middleman is likely preferable to Amazon (based on province goals, outcomes, and options available).

Not a fan of Amazon? Don't give them subsidies, revenue, favorable treatment, etc.
Thermal noise entropy is probably good enough for most practical uses, but it's still fundamentally producing a seed value that can be captured, misused, or bruteforced, right? Also curious if there are monte-carlo models looking at this to see "how uniformly random" they look.

Edit: I think figure 3 in this study is what I'm looking for. They define the inconsistency I described as "spectral pivoting".

> This discrepancy is because the Mermin-Wagner-Hohenberg theorem holds in the thermodynamic limit, while these simulations are for finite lattices

I think thermodynamic limit here means, it needs to be way too hot?

Top Documentary Director Alex Gibney Finds Billionaire Backer
I would suggest simply [a-z]:[A-Z], inspired by tr.

Then there is no syntactic special case. This is just EXPR:EXPR; the special case is that both EXPR are character class syntax, and so the tr-like range mapping applies.
Yes, we would play the multiple heaps version at restaurants - Make a triangle out of sugar packets. I still play it with my kids.

And yes - he invented the DigiComp II first, and Dr. Nim afterwards to convey the same concept more simply. There's a version with billiard balls at MIT Stata Center (https://scottaaronson.blog/?p=1902) and my uncle spoke there when they installed it. My mom and I are both constantly trying to get people to credit him, mostly successful, but there is at least one successful project that extended the idea and does not give him credit at all.

(Side note, I was curious if they weren't giving credit due to not wanting to imply infringing on patents, but a) looks like they're not close to infringing on the patent, and b) the patent is now owned by Crayola... https://patents.google.com/patent/US3390471A/en)

He also founded the first major startup in Pittsburgh, On-Line Systems, and I believe the second company ever selling mainframe compute (he phrased it as "second ever software business" but I'm pretty sure he meant second business selling compute, since I believe some unis sold compute before him), basically the OG AWS. And flew multiple bombing runs over Germany in WW2. I'll stop now, I think he's awesome but I'm biased.

> Many democratic countries have similar fundamental laws that are explicitly hard to change or bypass.

What exactly constitutes "hard to change"? In many countries, fundamental freedoms are regular legislation which can be overturned in the usual manner. Even a threshold of 2/3 or 3/4 to change is much easier to overcome than the federated constitutional amendment process in the US.
I would give the colon operator lower precedence than concatenation and repetition.

I'm of the opinion that youth protests (of any kind) for niche complaints (basically anything that your normie voter can't really get behind) only strengthens the executive. Protests are a great way to hook up and feel good, but I don't believe it moves the needle. Trump loves protests.

No one knows what the NEVCP is/or does. When Trump threatens Social Security payments (which he won't), then the People will rise up. In the meantime, enjoy the time off from work/school, the spring weather is lovely.

How do DOGE employees get paid?

If the answer is “they don’t” then they aren’t government employees or contractors and shouldn’t be inside private areas of government buildings and systems.

If the answer is anything else then it’s either a misappropriation of funds or an illegal private pay scheme.

Many of the largest US companies has local branches in Europe, and twitter is no exception here. In this case they have a branch office in Berlin. Im not a lawyer so Im not sure about the exact details, but if there is local presence then they are subject to the laws of that country like any other company, and enforcement should be similar.
Probably helps if the next time they try to remove the rights of large segments of the populace based on medical choices, lock people down, track them and propose vaccine passports, that you realize where everything is headed and oppose it vocally.

It's always through the appearance of good intentions and a public that pushes for whatever narrative they're fed that they normalize this.

People love and want more of this, not less.
Cloud Kootwijk: Local communications without foreign dependence
You need the same thickness of wire for 10A regardless of which voltage you have. So with 230V, your 10A wire will let you draw 2.3 kW while someone with 120V and 15A wire would only get 1.8 kW and pay more for the wiring.
Easy fix, impeach and convict the president.

It is not some million dollar RSUs getting vested by year end either way. A lot of them working for the love of craft and prestige. If they can just rollover on a technical disagreement then corporate office job is more suitable than open source OS kernel.
We have more than three interconnections that are not in synchronous connection to each other.

They can share power and are somewhat connected with HVDC interconnections however.
I don’t know is toaster are close to max power draw, but kettles certainly are.

Most places with 240V regularly have 16A sockets, allowing a maximum draw of 3840W of power. That’s the limit. Cheap fast kettles will often draw 3000W and boil 250ml of water at room tempature in 30s.

Kettles in the US are often limited to 15A and thus max 1800W (usually 1500W) and take twice as long (60s)

Technology Connections has a great video on this: https://youtu.be/_yMMTVVJI4c
Yes, but if that new middleman has less "economy of scale" types of prices, then it makes truly local alternative compare better, no?

In other words, let's say Amazon is 5% cheaper than all alternatives, including crude "aliexpress front stores" useless middlemen, banning Amazon won't make those stores magically cheaper. Therefore, it gives breathing space to all competition, including truly local alternatives.
It's always interesting to see different tools in this space. I'm glad that people are trying to innovate on CI/CD workflows. @pandiculation, have you checked out Dagger? How does EG compare with it?
It is called following local laws if you want to operate in the market under the jurisdiction of these local laws. You are free to not comply and then they are free to prevent you from operating. It is the same like individuals visiting/moving to this place. Being private/public company does not grant you immunity.
Is this based on census data?
The frequency drifts up and down whenever demand doesn't exactly match supply. Higher demand slows the frequency down, higher supply speeds it up. This is actually the main way power companies know if supply and demand match, and if power stations have to ramp up or down.

The frequency changes are pretty small in normal operation, but on a clock that uses the frequency to keep time they accumulate. They only work reliably because power companies know about them and occasionally deliberately run a bit over or under capacity to make the average match again.

Approved by congress but, apparently illegally, closed down by the President.

> At the heart of this case was the enforcement of a new legal provision under the DSA: the right to access research data (Article 40(12) DSA). This provision requires large online platforms to provide researchers with immediate access to publicly available data on their platforms in order to assess systemic risks. The lawsuit has also helped clarify open legal questions regarding the judicial enforceability of this right in Germany. [0]

How would we protect ourselves when the rule of law is non-functional?

This definition is quite literally the only check to balance power available to the average person, at least when it worked. There is no longer equality under the law which is dependent on the other components which have also degraded.

Congress is non-responsive to their constituencies.

We are stuck in a positive feedback loop, eventually when the abuses are great society will fall back to the natural state prior to the social contract. These will not be peaceful times.
The skin effect causes AC current density J in a conductor decreases exponentially from its value at the surface J_S according to the depth d from the surface. The depth decreases as the square root of frequency. This means that the effective power a wire can carry decreases with increasing AC frequency.

I still remember the time before the Internet, I can assure you the world was full of disinformation and misinformation, I believe way more than today.

Everywhere, in schools, in cafes, the bus stop people would tell you crazy things and people would argue about whether it is true or not.
If you really wanted to settle it you would need to find an encyclopedia, but most of the time you would need to go to a public library and find a book or go through microfilms for hours, make a copy and show it to everybody to fight disinformation.

Depending on the country, the government had a tight or tighter control on what was in that library.

Some country would also tightly control what was said in a bar or cafe like in East Germany.

So thinking we are in a life threatening misinformation epidemic is just false if you compare to just a few decades ago.
Yeah I mean I gathered that, still would be interesting to know what specifically he lied about.

A compromise here is not technically possible. There is no half crypto. Crypto with a backdoor is not crypto.

Ok, yes, there were some algorithms in the past which had problems with carrying input biases to their output and sometimes even getting totally broken with certain seeds/keys. Nowadays, this isn't the case, and the view is that such issues are fundamental weaknesses rather than mere errata to be worked around.

However, the quality of a modern CSPRNG doesn't save you from a low-entropy seed. A couple biased bits in a 128-bit seed may not be a serious issue (but why take the chance?!), however good entropy estimation is a difficult task which is best left to the operating system. Modern operating systems will ingest sources of hardware randomness and seed their system-level CSPRNGs, which should then be used directly by application software (for key material) or as seeds to local CSPRNGs (for less security-sensitive but more performance-sensitive needs). Do not play around with seed entropy just to be clever.

In the absence of a full-fledged operating system, then things like high-precision boot timers can be used for seeds, but only because there's nothing better available. The lack of good randomness is a real problem in resource-constrained environments, though usually there are easier-to-exploit vulnerabilities that get hit first.
You can give away Kindles too.
TBH, while I would like Twitter to be obligated to provide access to any data to anyone, I don't really understand on what grounds the decision was made. I mean, I wouldn't ask, if it was an USA court, where it's considered normal that any stupid judge can make any stupid decision, and it is called a precedent and must be respected. But in Germany there are laws, right? At least, theoretically. I mean, I personally don't believe in that, but any court decision is supposed be almost a natural consequence of the existing laws. So what is the law that makes a company obligated to do some work for free and send your data to some "researchers"? Honestly, I just don't like how it sounds, I kinda prefer libertarian anarchy, unrestrained mayhem and total impunity of various Musks to that kind of stuff.
Not sure which is worse. Sending data to China or the USA
