Basic LDL cholesterol is often covered by insurance, but ApoB, Lp(a), and hs-CRP are unfortunately usually not. If insurance doesn't end up covering it, sometimes the fee is just ridiculous.

For example, one person got billed $1,338 for just an ApoB test when insurance denied coverage: https://www.reddit.com/r/PeterAttia/comments/14a4an1/apob_te...

Part of why we do cash pay (and pre-negotiated pricing with the labs) is that you avoid weird catastrophic scenarios like this. The price is upfront and transparent.

It would probably be best to be able to fabricate lunar transport tires on the moon.

Which metals and other carbon-based materials handle temperatures ranging between -427F and 250F? Which of those materials can be fabricated with on the moon?

All-electric fusion induction welding would probably work on the moon (without filler gases).

> The appropriate place to find out what is and isn't true is research. Do research, write papers, discuss results, resolve contradictions in findings, reach consensus.

Few hot-button social issues are resolved via research, and I'm not sure they should be. On many divisive issues in social sciences, having a PhD doesn't shield you from working back from what you think the outcome ought to be, so political preferences become a pretty reliable predictor of published results. The consensus you get that way can be pretty shoddy too.

More importantly, a lot of it involves complex moral judgments that can't really be reduced to formulas. For example, let's say that on average, social media doesn't make teen suicides significantly more frequent. But are OK with any number of teens killing themselves because of Instagram? Many people might categorically reject this for reasons that can't be dissected in utilitarian terms. That's just humanity.

I worked in weather for a while and the forecasters might as well have been betting on the horse races, the interpretation of the charts was very much the same psychology.

The model did its thing but there was still an aspect of interpretation that was needed to convert data to a story for a few minutes on TV.

For longer range forecasting the task was quite easy for the meteorologists, at least for the UK. Storm systems could be tracked from Africa across the Atlantic to North America and back across the Atlantic to the UK. Hence, with some well known phenomena such as that, my meteorologist friends would have a good general idea of what to expect with no model needed, just an understanding of the observations, obsessively followed, with all the enthusiasm of someone that bets on horses.

My forecasting friends could tell me what to expect weeks out, however, the exact time the rain would fall or even what day would not be a certain bet, but they were rarely wrong about the overall picture.

The atmosphere is far from a closed system, there only has to be one volcano fart somewhere on the planet to throw things out of whack and that is not something that is easy to predict. Predicting how the hard to predict volcano or solar flare affects the weather in a few weeks is beyond what I expect from AI.

I am still waiting for e-commerce platforms to be replaced with Blockchain dapps, and I will add AGI weather forecasting to the queue of not going to happen. Imagine if it hallucinates.

Will AI put bookmakers out of business? Nope. Same goes with weather.

What about the stuff around George Floyd. Weren't people accosted and forced to kneel down and repent?

e.g. https://www.dailymail.co.uk/news/article-8664345/Aggressive-...

https://twitter.com/i/status/1269043437275435016

Etc.

Maybe some of them knelt voluntarily. But what would have happened if they hadn't. To me at the time there seemed to be a lot of social pressure to "kneel" and accept the narrative and the will of the mob.

And, more critically - if foreigners are deciding to take up faculty positions in their home countries.

Countries like India, Vietnam, and South Korea have begun replicating the Chinese Thousand Talents program to attract their diasporas back to domestic academia.

Significant domains of CS such as HPC/Systems, Networking, OS internals, etc are heavily dependent on faculty, graduate students, and post-docs who are all on some sort of visa. And increasingly, at least amongst Indians, becuase the backlogs for US citizenship are insane, a number of those people have been taking sweetheart positions at INIs like the new IITs with almost US$100k in public-private lab startup grants on top of a $20k salary (tax free due to the income tax changes) with free housing and car and complete autonomy to consult with private sector players without IP entanglement (one of the biggest headaches for public private STEM R&D partnerships in the US).

Vietnam is doing something similar as well to attract Vietnamese diaspora in SK and Japan, along with Viet Kieu in America and Australia.

A nativist academic culture in STEM in the US would completely destroy any R&D capacity that even exists today.

What kind of mobile functionality were you looking for? The (unofficial) iOS app is pretty good IMHO and integrates with iOS’s OS-level password filling, and also supports the pass-otp plugin’s format for 2fa codes if you use that plugin. There was a decent Android client I used a while back as well, though I don’t recall the name.

Back in the days when the music industry stole from artists the justification was that it cost money to pay for recording studio time, print records, set up distribution channels, promote shows, organize shows, and so on.

Then in the 90s, the cost of distribution went to 0 and by maybe the 2000s the cost of recording went to 0 in many cases.

Somehow the artists are still not getting paid well and instead of setting up distribution channels the labels are spending their time trying to prevent people from distributing too much.

And that's not even mentioning how much of the American music catalogue was stolen from local artists by music reps going state to state collecting songs and not crediting or compensating the performers. And then copied repeatedly by other musicians over and over.

I don't really have a point here other than that from one lens this all looks like a bunch of thieves complaining their stolen goods got stolen. From another lens it seems like we want to have good music and reward artist we enjoy. It's just less clear what exactly we're paying them for and how that should be collected.

It's hilarious watching the right wing embrace cancel culture now that they're in power. To be honest, I think most were waiting for a reason to go full mask off.

Trump started blaming the "radical left" before they had even caught someone. I'm still not convinced we have the persons full picture. Some of the terminology used hints at in-group memes from the "groypers"

He was also asked on a Fox News show what we need to do to avoid creating radicals on both sides and his response was the following:

"I'll tell you something that's going to get me in trouble, but I couldn't care less. The radicals on the right oftentimes are radical because they don't want to see crime. They don't want to see crime. Worried about the border. They're saying, We don't want these people coming in. We don't want you burning our shopping centers. We don't want you shooting our people in the middle of the street" "The radicals on the left are the problem," Trump continued, "and they're vicious and they're horrible and they're politically savvy, although they want men and women sports, they want transgender for everyone, they want open borders."

If you wanted to unify, this isn't the way. Witch hunts and dog whistles certainly won't help.

I for one do not want an airline pilot that praises an assassin, or my child to have a teacher that mocks people in mourning.

I do have political opinions, but I try very hard to stay back from a line that would mark my words as unprofessional. Social media has normalized behavior that would have brought termination instantly 10 years ago.

The firings are regrettable, but if they lead to more civil public interactions they are worth it.

Don’t do full stack. In fact avoid JavaScript all together except to make yourself more well rounded.

If you want to achieve employment as a fresh graduate in the current economy you need to look for areas that have the highest barriers of entry. Otherwise you will be competing against candidates with 8-15 years of experience that may not be very good at what they do but at least they have a stacked resume while you have nothing.

As a former JavaScript developer almost nobody knows what they are doing and most of those people are permanently locked into a mindset of expert beginner with 8 years of experience. Compare that to something like 3D graphics programming or financial modeling that requires actual smart people opposed to imposter syndrome pretenders.

Sure, but taken to an extreme you see the absurd degree you have to contort yourself. And that’s to the current version of the proof checker - some unsafe’s are even only temporary until a better prover comes by.

You shouldn’t go out of your way to use unsafe, but between that and 2 weeks refactoring, I’ll take the unsafe and use tools like miri or ASAN to provide extra guards. Engineering is inherently about making practical choices.

This wasn't a minor limitation; it was a fundamental capability gap. Users were forced to learn ClickHouse SQL, write raw queries, and maintain them as our schemas evolved. We'd built a query builder that couldn't handle real-world queries.

Prior to being fired, was Dowd a "spokesperson of MSNBC"?

I don't think so, and I don't think this is a fair way to characterize Kilmeade either.

I'm not really convinced.

It beggars belief that this would lead to de-escalation from Trump's opponents. In fact, I've seen him take a conciliatory tone before, only to get decontextualized and further vilified.
by borroka | 2025-09-14 02:42:57+00:00
I appreciate the comment, but it is not what I said, and I would not be that dismissive. I am very familiar with the literature.

As for the first part, yes, we sometimes get caught up in, like, the illusion of fluency, but you can also check how much you've learned, and we all get that there are differences between days within subject.

I have practiced decent-to-highish-level sports all my life (soccer, Brazilian jiu-jitsu, tennis and others), and now I am learning a new one (ping-pong), partly because I want to test some theories about learning, and there are days when you learn better—-you are better. We all know that.

Apart from the vagaries of life, it is my experience and belief that the way you approach a challenge plays a significant role in the quality of the experience.

As for the second part, yes. But you can see this in sports too, and I find it bizarre that cognitive abilities are treated differently from motor skills, given that repetition, climbing up the skill tree, and retrieval practice should be common learning methods. Even top player retrieve and refine continuously basic motor skills.

My approach to the issue was broader and more related to self-confidence, the perspective of having opportunities and potential, and relaxation, all aspects that can be greatly improved by the systematic practice of autogenic training. Now, the ‘funny’ part is that we all know the above (no one has ever said, ‘be as tense as possible and you will learn more’), but it is something we say and think much more than we do.

Let me present a silly example. I like cooking, and when discussing it, some say, "I am not good at cooking" or "I am terrible at cooking", which is, of course, an issue of attitude. There are recipes everywhere, millions of video showing people cooking, there is nothing to invent for the home cook. What I say is, "You won't become the next Ferran Adriá or Massimo Bottura, but I am sure you can cook something delicious, if you just follow the recipe."

How many of us say things like, “I'm not good at ironing, I'll never learn how to do it.” Of course, you can learn. You may not become as good as my grandmother with shirts (according to family lore, she was by far the best), but it's certainly not impossible to learn to do a decent job. Some might say it's laziness, but you can acquire the right attitude through systematic practice.

The same applies to languages: since I speak several languages, people ask me for tips and tricks. After observing dozens of people who have gone through this experience, I can say that there is a wide variance in aptitude, but a positive, winning, and proactive attitude makes a huge difference in the outcome. However, you need to build and reinforce it through systematic training.

The biggest issue with sub-agents and even the CC Task tool is that they are black boxes, and we can’t see what’s going on inside them and cannot intervene. I’ve instead often found it better to leverage Tmux and have CC send messages to another CLI-agent (could be CC or the other now-surging CC, i.e., Codex-CLI, or of course any other competent CLI-agent) running in another pane. To make this smoother I built this Tmux-cli command that CC can use:

https://github.com/pchalasani/claude-code-tools/tree/main?ta...

If the first CLI-agent just needs a review or suggestions of approaches, I find it helps to have the first agent ask the other CLI-agent to dump its analysis into a markdown file which it can then look at.

Cheers! 10% is nothing to scoff at!

...While I have your ear: IME ReThink DNS often runs into bootstrapping problems since 1) preconfigured DNS servers are referenced by hostname, not IP 2) I can't find a way to separately configure server address and TLS name (making it impossible to configure DoH/DoT servers via IP).

So users often run into "catch 22" where they need existing DNS to resolve their DNS server... When roaming it may work fine for a bit until the local cache drops it, and so on.

Allowing to separately configure TLS hostname for TLS-enabled protocols, and having a preseeded list of IPs for bundled provider endpoints, would mean ReThink DNS could work reliably even in absense of existing DNS.

The article mentions political polarization increased most in seniors (65+).

Social media or not, I would guess it’s largely because many retirees don’t have anything to do. They’re isolated. They want connection and purpose. While younger adults have jobs and obligations.

My retired dad lived alone. He could talk nonstop about that crazy thing Trump did, but I wasn’t following closely, and somewhat tuned my dad out to not get lost in a rabbit hole. My dad got this from cable news.

Isolation to me is the root cause at any age. People who only see the world through media (social or otherwise). It’s easy to become radicalized when you don’t have any attachments other than your political affiliations.

I asked for a dipthong. The generated photo was interesting but ...

> The Diphthong is a specially crafted musical instrument consisting of two entwined harmonicas emitting dissonant tones when played simultaneously. Its unique design allows players to generate unstable vibrations within their vocal cords upon inhaling through either end. The resulting sounds defy linguistic classification and evoke feelings akin to euphoria among listeners who understand the concept of connotative ambiguity.

I disagree with that.

Instead we are seeing increased siloing of scientific domains. The EU is cracking down on EU-Chinese research cooperation (as recent arrests and deportations in France have shown), India still has a de facto freeze on Chinese R&D and China is still enforcing export controls on IP to India, and South Korea and Japan are still controlling any IP generated from their industrial research fusion programs.

We're instead seeing at least 6-7 different scientific and capital ecosystems forming, and with collaboration being tightly controlled by governments.

Really? With people being tracked down and fired for expressing their political views, it seems like online anonymity is more important than ever.

Or better yet, we need some kind some zero knowledge doodad which enforces scarcity of anonymous handles such that a given voice is provably a member of your same congressional district, or state, or zip code, or whatever, and is known to not be spinning up new identities all willy nilly like, but can't be identified more precisely than that.

i only cited it as a side note for the upper bound. the more conservative estimate of the scientific service of the Bundestag still shows that your claim of zero subsidies is made up and unsubstantiated. Discrediting the radical other position and ignoring the center positions does not make your own radical claims true. I can give another source: "Aufstieg und Krise der deutschen Atomwirtschaft 1945-1975" by historian Prof. Dr. Joachim Radkau. However that one you have to get from a library, it describes in detail how the nuclear industry in germany was build and what role and subsidies the government provided.

Something I have been considering is a ETL pipeline that, for each customer in our system, writes only their data to a SQLite file. Then, just expose a full SQLite query facility on that file.

This only works when your customers are of a reasonable size (e.g. small businesses or individuals) but could provide arbitrary analytics power.

It's also a safe target for AIs to write sql against, if you're into that sort of thing.

-ldl is computed on the standard panel, not an actual measurement

-accidentally got lp(a) twice and it varied quite a bit, so they may use different labs that are calibrated differently

> Indian spaceflight program done by ISRO have very few people from IITs or any of the so called elite colleges

The bulk of recruitment at ISRO has always been happening at the Indian Institute of Space Science and Technology (IIST) and the Indian Institute of Sciences (IISc) - not IITs.

Even getting into an IIST or IISc is almost as difficult as getting into an old IIT based on the JEE cutoffs.

Both India and China have specialized institutions dedicated to subfields that end up getting the bulk of R&D funding in said subfields, for example, Petroleum Engineering and the China University of Petroleum and the Indian Institute of Petroleum Engineering, or in mining enigneeing, the China University of Mining and Technology and the Indian School of Mines (now IIT Dhanbad).

> Unlike china Indian colleges are really backward due to lack of research funding and a coaching industry which have gamified the entrance exams

China also bases acceptance on entrance exams - the Gaokao is equally as competitive as the JEE Advanced. The exact same gamification of entrance exams and coaching centers is sadly the norm in China as well, despite the Xi admin's initial attempts to crack down on it.

Additonally, Chinese R&D funding is also stratified the same way Indian R&D funding is.

The equivalent of a government engineering college in both China and India would be receiving relatively limited funding or autonomy, but a Double First Class University in China or an INI in India well get the first pick of research grants and subsidizes.

If there is a promising professor at a mid-tier program, they are likely affiliated and getting their funding via affiliation to a national academy like the Chinese Academy of Sciences.

They asked if it could be "as fast as the JVM", which JIT is a crucial part of how the JVM achieves its performance. JIT in this context is referring to the process of a source file (.rb, .js, .c, etc), or usually bytecode, being compiled into machine code. I cannot think of an instance where a C source file is JIT compiled and dlopen(3) will not be happy if you tried to call it on a C source file.
