Also I don't think the equivalence between edge/vertex versions is trivial at all (though maybe we just have different standards of triviality).

For example, in a grid like this:

..####
.....#
#.#..#
#...H#
######

A single wall placed (i.e. vertex removed) can block two edges, and it's not obvious what graph transformation can turn that into a single edge.

Says you? because that's not what cardiologists, nutritionists and doctors say. around the world. there's a ton of real, good science from many countries that show a very clear link between increased saturated fat intake, CVD and LDL-C levels. It's not really in question.

You are essentially hand waving away 80+ years of scientific studies and data because...you said so?

> you really shouldn't trust a doctor about any of this stuff any more than you should trust the latest health influencer crackpot.

This is an insane take and thoroughly discredits anything you have to say. Science has some basis in reality, even if it is somewhat flawed. The idea that we should throw out all science food guidelines because it's not perfect is completely crackpot.

I have no idea why nutrition brings out the crazy left field engineer types but it's a common pattern.

> I guess what I'm lamenting is the missed opportunity to highlight that many vegetables e.g. broccoli are an excellent protein source as well as other important nutrients

I can see why you would expect something like that from this administration, but surprisingly the linked webpage seems to be based in fact.

Broccoli are not an excellent protein source from a dietary perspective.

Read that as "speed of lines of code", which is very VERY very different from "speed of delivery."

Lines of code never correlated with quality or even progress. Now they do even less.

I've been working a lot more with coding agents, but my convictions around the core principles of software development have not changed. Just the iteration speed of certain parts of the process.

This has been the running theme so far: Big talk to energize the base and make a splash, followed by actual policy implementations that are much more down to earth.

Remember all the talk about banning COVID vaccines? In the end they just changed the wording of the federal recommendations and included things like "having a sedentary lifestyle" as one of the vague reasons to get a COVID vaccine. In some states you had to get a doctor to write a prescription, annoyingly, but the overall picture is that it's still much easier to get a COVID vaccine in the US than under something like the NHS.
by orochimaaru | 2026-01-07 21:25:36+00:00
You went on a bit of a rant there - lol. I like the new guidelines they explicitly disavow processed food. As for vaccines, not everyone complaining about specific vaccines is anti vax.
A lot of vaccines are also region specific. Eg HK does TB vax for kids because Nannie’s from Indonesia carry TB. No one does the TB vax in the US.

A lot of vaccines are tailored towards the mother going back to work. They could be tailored for a later schedule if there is concern about secondary effects like autism and the child is being cared for at home.

Again I’m not anti vax but I also don’t think the protocol designers are providing alternative options which they should.

Humanity survived - but a lot of individual died that wouldn't today. As a parent I don't want to see most of my children die before they reach 5. I've been to more funerals of children in my life than I want to. The vast majority of the children I've ever met will see their 65th birthday: because of vaccines and modern drugs.

My wife would also hate having to give birth a dozen times just to get enough children (that much unprotected sex is fine with me). I don't want my wife to die in childbirth which was fairly common before modern drugs as well.

The semicolon is required only when not using new lines to split the command words, as in

sleep 60; do_the_thing_that_needs_a_minute_wait

It's not necessarily required in the for loop either, I tend to prefer the more compact method of putting the "do" on the same line as the for. It can be written as

for i in {1..10}

do

print $1

done

Having "done" be the signifier of the "the for loop context ends here" is 3 characters more than "}" or ")" or whatever else. "done" is more color coming off the screen with syntax-highlighting, and can be typed in two keypresses with a "d" and a "tab" in any editor from the last 30 years. It just seems like a very very inconsequential nitpick. At least Nushell doesn't pull a Python and just have "invisible space" be the end of the for-loop.

One line conditionals are doable as well in the shell.

test -f junk && junk

or

[[ -f junk ]] && junk

You can even just use [ -f junk ] if double brackets is giving the yuck.

> There were purges aplenty during the Communist times, to make way for loyalist bureaucrats. What's taking place is the incipience of not just a stable regime but a calcified one.

If it were calcified, you'd probably have a lot more willingness to bet on a business decision being profitable. There'd be a very obvious, solid understanding of market rules and there would be little likelihood of them changing.

The problem with Trump - well, in this regard; there are plenty of others - is that he is used to operating as an absolute monarch, with his previous "kingdom" being the Trump Organization. That kingdom existed purely for his benefit and there wasn't really any consideration of peers like you'd have with actual kings who rule over countries with societies and borders. The only decisions he had to make right were the ones benefitting him, and whether or not they did that was quite evident.

Now he's a leader of a country that does have borders and a society. There are parties with interests that he must satisfy. You can tell he's never had to do that before and part of how he handles that is to just bully those parties into submission, but the other way is to use his status to make proclamations that supposedly have some sort of force to them to placate the other interests.

An example would be the proclamation that institutional investors will be banned from buying single-family homes. That's meant to placate his working-class base, most of whom can't afford a home. Do we know how far he'll go in enforcing that proclamation? No. It directly contradicts some of the other positions he's been identified as supporting, and is unlikely to be enforceable on a mass scale, but if he does sign some sort of order telling the DoJ or SEC or whoever to investigate purchases of that sort of real estate by institutional investors, well, you could end up at the wrong end of a government investigation, particularly if you have somehow pissed him off. Which isn't particularly hard to do, either.

Thus, you can say the regulatory regime over single-family residential real estate market is now less stable than it was before. We don't know what will happen. And that makes it hard to make a business decision around it.

> Emojis and other symbols introduced new notions like colors that were not present before. I'm no longer certain that it is feasible to handcraft a font thwt contains all the symbols for codepoints affected by color modifiers.

Color modifiers are just ZWJ sequences. Those existed before. The color modifiers themselves are not the most complicated things that get attached to ZWJ sequences among languages that Unicode supports.

OpenType today supports color tables that mean most emoji modified by colors aren't "handcrafted" but algorithmically constructed. (As many ligatures and other ZWJ sequences often are.)

> Also, 8 bit codepages, for all their problems (a different kind of hell), didn't break the assumption that each character is encoded as one byte.

That is broken in other 8-bit codepages as well, it was just seen as an exception/edge case rather than the rule. The big obvious exception has always been \r\n (carriage return then newline), but there's also ^H (control-H) and ^W (control-W) sequences (effectively backspace and delete word), and the entire gamut of things done with ANSI and/or VT100 escape seqences starting with Escape often stylized as ^[.

> And UTF-8 specifically gives the illusion to English speakers that using naive 8 bit string handling works.

Unless emoji are present, which is one of the great things about emoji and emoji becoming a very common form of punctuation in English text. Naive 8-bit string handling was always wrong. Emoji help make it visible how wrong it was. (In part by doing things other languages do such as ZWJ sequences and having code points out in the Astral Plane and other such features.)

I'm surprised that governments didn't take this problem more seriously. Obesity is a huge problem, people have been ignoring it only because improvements in medicine have been offsetting the general health decline. Without the medical improvements that save the life of obese people, life expectancy would have decreased. I don't expect the Trump administration to make the best decisions but at least they are taking it somewhat more seriosly.

People are very good at ignoring warnings, I see it all the time.

There's no way to design it to minimise misinformation, the "ground truth" problem of LLM alignment is still unsolved.

The only system we currently have to allow people to verify they know what they are doing is through licencing: you go to training, you are tested that you understand the training, and you are allowed to do the dangerous thing. Are you ok with needing this to be able to access a potentially dangerous tool for the untrained?

Zero free parameters. Here are the top three predictions:

1. Stack 12 oranges around one. Square it: 144. Multiply by electron mass.
Result: Σ−Λ = 73.58 MeV
This is the mass difference between two types of baryons (Σ and Λ particles).
Experiment: 73.60 MeV. Error: 0.02%

2. α⁻¹ = 4π³ + π² + π = 137.036
The fine structure constant — it controls how strongly light interacts with matter.
Feynman called it "the greatest damn mystery in physics."
Turns out: 4π³ (volume) + π² (surface) + π (circumference). Just geometry.
Error: ~2 ppm

3. ρ_Λ/ρ_Pl = π⁻²⁴⁷
The ratio of dark energy density to Planck density.
Quantum theory predicted this wrong by 10¹²² — the "worst prediction in physics."
This formula fixes it. Error: 1.1%

The notebook verifies 7 "Crown Jewel" predictions (mean error 0.014%) plus additional tests across particle physics and cosmology. Runtime: ~5 seconds.

This isn't numerology — the kissing number K₃=12 is a proven theorem (Schütte-van der Waerden 1953). The E₈ lattice (K₈=240) won Viazovska the Fields Medal in 2022.

As I’ve already told you, the industry says they lose 1.6% to shrinkage and theft is just a subset of shrinkage.

So your figures are flat out wrong.

And I get it’s a gross figure, I was just putting it into simple terms for you because you’ve managed to misunderstand every other comment thus far. I was hoping turning the figure into a fraction might help you understand the ridiculousness of your comments. It was meant as an illustration rather than a literal scenario.

Anyway, like the other guy, I’m done chatting to you now. I’ve done business studies and worked in retail before moving to IT. Clearly you haven’t. And if you’re going to keep repeating incorrect figures then you’re beyond reason anyway.

There was a very similar private security guard case to this a few years ago where the security guard was yelling at someone to leave but then physically blocked their car. When the person moved, the security guard shot them.[]

He got roasted in court because he had given conflicting commands, and also because you can't put yourself in jeopardy just so you can shoot someone that's running away (police can but only fleeing felons). Life sentence.

This appears to me what happened here. She was committing a misdemeanor, and running away from the misdemeanor. Police explicitly asked her to move her vehicle. After she finally did so they stood in front of her to intentionally put themselves in jeopardy so they would have a reason to "defend themselves."

I have a feeling it will be a very long and dicey trial that ends up in a hung jury. Hopefully Minneapolis doesn't experience riots due to this; but it would prove the exception.

I don't think it's even about low carb vs. high protein to begin with. Many countries and regions in the world are fine with a high-carb diet, and people there live long, healthy lives.

Americans eat so much processed food simply because it is much cheaper than fresh food. Processed food is made to get consumers addicted (through convenience, taste, etc.) and encourage them to consume much more. Fresh food is almost the opposite.

I grew up in a country where freshly made food is actually cheaper than processed food, even to this day. People who stick to a traditional diet are mostly thin, while those who stick to a processed food diet gain a lot of weight.

Not to support this particular but most doctors would advise "minimized or avoided" use of any medication during pregnancy, including OTC meds. Not that there aren't good reasons to sometimes use them, but you probably should not think it's OK to chug Nyquil every time you get a runny nose if you're pregnant.

I personally avoid all meds that aren't prescribed. I haven't taken a Tylenol or Advil or Sudafed or anything like that in years. I take some vitamin supplements and occasionally (but rarely) will use aspirin for a headache.

If it doesn't revert the corrections, maybe it is progress?

I can easily imagine constant churn in the code because it switches between five different implementations when run five times, foing back to the first one on the sixth time and repeating the process.

I gotta ask, though, why exactly is that much code needed for what CC does?

It's a specialised wrapper.

Sure, and that goes even for myself. Like for example, on some projects maybe I'll be more interested in exploring a particular architectural choice than actually focusing on the details of the feature. It ultimately doesn't matter, the point is that you can choose where to spend your attention, instead of being forced to always go through the all motions even for things that are just irrelevant boilerplate

Once you try to clamp down on investment properties, you have couples getting divorces so they can own two homes (this happened in China), and all your kids are going to have their own home as well.

It isn't a bad idea, people will game whatever. A singapore public housing system might work better, but I doubt it would work for SFHs.

"Isn't that basically what we've been doing with dietary guidelines since the 80s?"

If by this you mean to ask if the new guidelines are the same as previous ones from the 80s, then no. The new pyramid is different, makes different recommendations (more meat, for instance, and less wheat and grains). The website linked to explicitly shows how it is different from the previous "food pyramid" guidelines.

The link you gave doesn't support your claim that saturated fat is good.

In fact, from the very same site, here's another article saying it's not: https://health.clevelandclinic.org/saturated-fats-finding-a-...

Saturated fat is OK in moderate amounts, but if you eat too much, it drives up your cholesterol because your body converts saturated fat into cholesterol[1][2].

The issue I have with this new food pyramid is the guidance ignores the danger of saturated fat. It lists "meats" and "full-fat dairy" among sources of "healthy fats", and that's just not true. In the picture that shows sources of protein/fat, 11 out of 13 of the items are animal-based fats. With a giant ribeye steak, cheese, butter, and whole milk specifically (not just milk), they're simply not giving an accurate picture of healthy fat sources.

I personally don't think seed oils are bad, but even if they were, it does not follow that saturated fat is good. The evidence shows otherwise, for one thing, plus it's not like seed oils and saturated fat are the only two kinds of fat. There are plenty of unsaturated fats which aren't seed oils.

As I commented [1] on the earlier Claude Code post, there's an issue [2] that has the following comment:

> While we are always monitoring instances of this error and and looking to fix them, it's unlikely we will ever completely eliminate it due to how tricky concurrency problems are in general.

This is an extraordinary admission. It is perfectly possible (easy, even, relative to many programming challenges) to write a tool like this without getting the design so wrong that the same bug keeps happening in so many different ways that you have to publicly admit you're powerless to fix them all.

> an entire ecosystem

Ecosystems have their downsides too. Just a small example, no htmx users were impacted by the React Flight Protocol vulnerabilities. Many htmx users have no-build setups: no npm, no package.json, nothing. We don't have to worry about the security vulnerability treadmill and packages and tools arbitrarily breaking and no longer building after some time passes. We just drive the entire webapp from the backend, and it just works.

Integration with Function is a great use-case. There is a huge category of pre-diagnostic health questions (“Medicine 3.0” as Attia puts it) where personalization and detailed interpretation of results is important, yet insurance typically won’t cover preemptive treatment.

Not to mention that doctors generally don’t have time to explain everything. Recently I’ve been doing my own research and (important failsafe) running the conclusions by my doctor to validate. Tighter integration between physician notes, ChatGPT conversations, and ongoing biomarkers from e.g. function and Apple Health would make it possible to craft individualized health plans without requiring six-figure personal doctor subscriptions.

A great opportunity to improve the status quo here.

Of course - as with software, quality control will be the crux. We don’t want “vibe diagnosing”.

Russian goal is to control whole Ukraine like they control Belarus. This is not achievable. Not with the current state of Russian logistics or state of Russian economy.

One of the reasons why is Russia struggling is absurdly arrogant denial of reality. Why they are negotiating with USA, which has more and more marginal role in the whole conflict and not addressing the blue elephant in the room, European Union, which is bank rolling Ukraine and arming it?

Once those additional vaccines are off the "routine" schedule, they'll be pulled by the suppliers, because it eliminates exemption from lawsuits. If you "choose" a non-routine vaccination, people can then sue pharma for ANY harm, and you can be sure there'll be a bunch of crackpot right-wingers trying to prove each one is "bad" and they'll disappear sooner or later. RFK's fans (Del Bigtree) have admitted that this is their plan. And if they're NOT routine, they'll probably not be covered by insurance, so you'll have to pay hundreds or thousands to get one. I would still do that, but not many others will.

Electing to get all ZERO optional vaccines actually available to you because of "reasons" isn't much of a choice.

Is it possible for humans to review that amount of code?

My understanding of the current state of AI in software engineering is that humans are allowed (and encouraged) to use LLMs to write code. BUT the person opening a PR must read and understand that code. And the code must be read and reviewed by other humans before being approved.

I could easily generate that amount of code and make it write and pass tests. But I don't think I could have it reviewed by the rest of my team - while I am also taking part in reviewing code written by other people on my team at that pace.

Perhaps they just aren't human reviewing the code? Then it is feasible to me. But it would go against all of the rules that I have personally encountered at my companies and that peers have told me they have at their companies.

For the same reason Microsoft never has and never will chase people for pirating home Windows or Office licenses

When they hit the workforce, or even better, start a company guess which OS and office suite they'll use? Hint: It's not Linux and Openoffice.

Same with Claude's $20 package. It lets devs use it at home and then compare it to the Copilot shit their company is pushing on them. Maybe they either grumble enough to get a Claude license or they're in a position to make the call.

Cheap advertising pretty much.

Worked for me too :) I've paid my own Claude license for over a year at home, grumbled at work and we got a Claude pilot going now - and everyone who's tried it so far isn't going back to Copilot + Sonnet 4.5/GPT5.

The only change from the previous dietary recommendations that I can see is that they recommend a bit of a smaller portion of veggies and a bit of a bigger portion of protein. Everything else seems exactly the same.

I think it's mostly just that there's loud talking points now and they're marketing it heavily to make it feel like it's their idea when it's already been the official guidelines for a while.
