You can do a lot with chaos. One of the things it lets you do is find an unforced trajectory from the vicinity of any state to the vicinity of any other (accessible) state. Sensitivity to initial conditions means sensitivity to perturbations, which also means sensitivity to small control inputs, and this can be leveraged to your advantage.

Multibody orbits are one such chaotic system, which means you can take advantage of that chaos to redirect your space probe from one orbit to another using virtually zero fuel, as NASA did with its ISEE-3 spacecraft.

>He said LDL does not do anything on its own

It's like saying a flying bullet can't do anything on its own. It is a meaningless statement.

>As I pointed out in another post over 75% of people who have heart attacks have normal LDL.

The actual study authors were advocating for lower LDL guidelines, particularly among the elderly.

A heart attack is the destination, not the journey. What someone's LDL was at admission for a heart attack says literally nothing about their state for the decades before. In actual studies tracking cholesterol, even over a five year period lowering LDL has a potent beneficial effect.

>You’re saying a lot of nonsensical stuff in your comment like high blood pressure causes inflammation , which tells me you are not serious in this discussion

Hypertension can cause endothelial inflammation, leading to blood vessel damage and promoting the release of inflammatory mediators. This is extremely well documented, and it's why getting hypertension under control medically is considered extremely important in the CVD battle. Inflammation and hypertension often are found hand in hand, and there is uncertainty over the cause and the effect, but strangely controlling hypertension alone dramatically reduces inflammation. Weird, right?

>I have zero inflammation

Sorry, but LOL. Not only is that a singular and very narrow test, inflammation is literally just a facet of living. As is oxidization. There isn't a single human alive with "zero inflammation", nor is there anyone that has magically non-odidizing LDL.

A little off-topic but I’ve been waiting for a post by someone who’s built something like Claude Code or Codex that can explain how the state machine works for execution.

Clearly it’s not just a good system prompt and hoping for the best. Obviously they’ve both got fairly good algorithms for working toward whatever the user asked for incrementally, handling expectable errors, changing course if necessary, etc.

I mean ultimately it’s gotta be a really big flow chart that results in the LLM getting prompted various ways in all kinds of directions before ultimately converging on the final response, right? Or am I way off-base?

Has anyone seen such a post explaining this architecture / state machine / algorithm?

Smaller and cheaper is the direction I’d like to see cars, and especially EVs take. It seems so inefficient to proliferate large, very heavy vehicles, just to move one or two people around. Most people’s transportation needs almost certainly are to go to work and shopping, but vehicles seem optimized for family cross-country road trips.

Smaller vehicles need smaller batteries, smaller motors, less energy to move, and put less wear and tear on public infrastructure. If the interiors are nice, I think there would be a market for them. Perhaps government policy could encourage efficient use of valuable resources too.

I agree! We're definitely not trying to avoid them as users haha, I can certainly see how it would be useful. There's so much automation that just can't fit into a strict schema, and always needs a human or customization for 10% of it

We're aiming to be flexible enough, so that if you can do it in a terminal then you can _also_ do it with a runbook

Not OP but

- Terminal search and focus (you can list kitty tabs and windows and get the window content from the socket, implementing a BM25 based search is quite easy)

- Giving the current terminal content for AI, so I can do things like run `ls` and then write "Rename the files (in some way)", and push the whole thing to LLM that replaces the command line without me having to write the full context

I even have a Codex session finder that uses codex session files to list and select the session I want, and then uses the kitty socket to find and focus the window which matches the session content

I feel like the main problem with buying clothes online is there is no way to tell if they are actually good or fit right. The photos are all fake where it's just an image projected on a stock photo of someone in a shirt. Doesn't tell you what the material is like, doesn't tell you if it actually fits (an AI video model is just making up the fit).

I think you're right on this one. Children have an immense amount of practice time, support and social pressure to learn a language.

The only thing that seems to be different between adult and child learners is acquiring specific sounds/tones. I know many good speakers of English who cannot distinguish L/R sounds. I basically cannot hear pitch accent differences in Japanese despite having spoken it for over a decade.

I wonder about the importance of minimality: it itself seems like a heuristic for “interest” or some other thing that users of diffs actually care about.

For example, a diff like:

+ x += 1 - x -= 1

Seems almost useless: it doesn’t provide any context about the meaning of x and, as a result, nearly every source review tool provides unchanged line in addition to highlighting the change. And, even then, by preventing comments on arbitrary lines of the file, GitHub’s code review makes it pretty hard to call out other relevant code.

The first pattern-matching language I used was Erlang. I generally like Rust's just as much, but Erlang/Elixir's binary-matching syntax was awesome and is sorely missed:

So apparently the city didn't want people to build homes in much of the affected area due to risk of exactly this, but property owners sued to be allowed to build anyways.[1]

Now what the city feared would happen is in fact happening and the city has to bail them out, buying properties?

Also let me guess: the people who sued the city back then to be allowed to build their homes are now suing the city because their homes are about to relocated below sea level.

Maybe it's time to tax leeches and stupidity in general.

I like the humourous way of putting it, but of course Zeno and his contemporaries knew that things moved - that's exactly why this seemed to be a paradox. Seemingly secure reasoning results in a conclusion that's obviously false.

To resolve the paradox, you have to show what's wrong with the reasoning, not just observe the obviously false conclusion.

Looking at the filings, it's not clear to me what the $250k "Program Services" were, or the $122k "Other Salaries and Wages" are.

I guess there could potentially be additional non-salary compensation, i.e. using another business to charge fees of the non-profit?

Looking closer at some filings there's also "$9k travel expenses" "$4k office expenses", "$12k IT expenses", which could potentially be supplementing his compensation as well.

I wish that the diff/patch would be able to better take into account moved data (not only as deletion+add but with with a proper semantic indicating the moved block). This would both lead to smaller and more readable patches.

You don't solve the problem by "humbling the workers".

The solution is rewarding people when a company is successful and more importantly not punishing hard workers. Right now people are under the impression that slacking and working hard will be equally rewarded, because that is the truth. Hard workers also get laid off so that CEOs can make a few extra bucks.

There is a detailed lipid panel (Lipofraction NMR) as along with the HDL/LDL/TriG estimates they get today. There is a lot more detail in there. Statins help reduce LDL but the detailed lipid panel may still show a very high level of LDL-P and Small LDL-P which still increase risk.

If you're going for more testing, I would definitely suggest the lipofraction.

ultimately we see this play out quite a lot, predatory people cry when they’re preyed upon.

time and time again they justify predatory behaviors and then cry foul when someone figures out a way to take them. “it’s ok when i do it but we shouldn’t allow it when im on the wrong side!”

it’s wild how commonplace predatory shit has become in so many facets of society now.

Not at all, you are stuck with a machine that has only 256GB of ssd(and not upgradeable) and 60hz LCD screen, also only 2 IO ports.

I have quit a dev job exactly one time, when offered a salary the first one wouldn't meet (the HR person straight up told me she didn't understand why they would pay me $80k in the exit interview, this was like 6 years ago). Since the second company pays me well (with benefits), gives me yearly raises, and gives out generous performance based bonuses, I haven't looked for another job since then. And yes, job #2 is often boring.

It's pay. It's always been pay.

Maybe.

Back in the olden days, you needed to be a hero who knows all the innards of your 8 bit machine just to produce a decently playable game that was more sophisticated than Tetris. These days even an idiot like me can hack something together in a high level language like Python or Rust. That's progress!

Similar to how everybody carries an awesome digital camera around with them today. The absolute number of photographers has increased dramatically. And even the absolute number of great photographers has increased dramatically, because constant practice helps.

But I'm fairly sure the skill and dedication of the average person engaging in photography has dropped equally as dramatically: that's how lower barriers to entry look like.

I don’t want anyone “eliminated”… the problem is what does “eliminated” mean? If it means “rounding up people and shooting them” then of course I oppose that. But what about the conservative Jew/Christian/Muslim who believes that when Moshiach/Christ/Mahdi comes/returns, gender dysphoria will cease to exist-is that belief also “eliminationist”? I think religious freedom means we need to tolerate the existence of such beliefs even if we believe they are wrong. Excluding someone from an open source community because they hold traditional religious beliefs on gender and sexuality-especially if we assume they keep those beliefs out of project forums where they aren’t relevant-that’s religious discrimination, and in my view it is wrong, and (in some jurisdictions) it may even be unlawful

Same here. I have an M1 Max with 64GB and the only time I notice a slowdown is doing Rust release builds with `lto = true` and `codegen-units = 1`, which makes complete sense. Otherwise there is _plenty_ of multicore performance for debug builds, webdev, web browsing, etc., often all at once.

Gmail significantly improved the email spam situation for everyone by aggressively pushing email security standards like DMARC/DKIM/SPF [1]. This came at the cost of basically no longer being able to selfhost your own email server though.

I agree with the other commenter, I use Fastmail and I get very few spam emails, most of which wouldn't have been detected by gmail either because they're basically legitimate looking emails advertising scams. I have a Gmail account I don't use and it seems like it receives about the same amount of spam, if not more.

"Approval" / "Golden Master" / "Snapshot" / "Characterization" testing can be very helpful.

They all seem to be names for more or less the same idea.

The first time a test runs successfully it auto captures the output as a file. This is the "approved" output and is committed with the code or saved in whatever test system you use.

The next time the test runs, it captures the new output and auto compares it with the approved output. If identical, the test passes. If different, the test fails and a human should investigate the diff.

The technique works with many types of data:

* Plain text.

* Images of UI components / rendered web pages. This can check that your code change or a new browser version do not unexpectedly change the appearance.

* Audio files created by audio processing code.

* Large text logs from code that has no other tests. This can help when refactoring, hopefully an accidental side effect will appear as an unexpected diff.

I built a tool to help identify programs that are phoning home, normally to check for updates and the like.

It uses a BPF program running in the kernel to monitor traffic which is later analysed in a Java user space program.

You simply setup a WiFi hotspot on a machine that has this installed and allow the devices you want to monitor to connect to it. Leave it for a while and check for any patterns it has identified.

This project is ready to use as is but I do intend to keep adding to it. Please let me know if you find something interesting!

Hey Brendan! I also would love to add Canadian maps, it's been a huge request from my users and something I've been wanting to focus on all year. A big challenge I have in bringing the service to new regions is just data access, both to raw hi-res map imagery as well as to satellite, LiDAR, etc so this is on my todo list to begin digging into what the Canadian government offers.

The whole idea of gambling is predicated on the idea that you can win. If winning can cause you to get banned, the premise of the business is a lie. It's basically false advertising, and these places should not be allowed to claim (or imply) you can win anything. Basically the only thing they should be able to advertise is that they will take your money.

I read a really interesting post in The NY Times (having trouble finding it) that really broke down how crazy sports betting has gotten in the last couple years. The gist is that states love betting, because they can tax them at high rates with little pushback from citizens who are marketed that the money goes to schools. The sportsbooks have to eat the new tax, and change the odds so that they can make a profit. This forces more losers in the state, and causes possible indirect costs from people losing so much. It’s an ugly cycle where no one wins.

I’ve thought about making a Venmo for betting.

Start a betting pool with a group of friends. Use an exchange (not sports book) internal to the group, so no external money needed. No commission.

It’s no fun realizing you and your friends have taken opposite bets and are just handing money to the house. Keep that money in your social group and make some friendly bets without worrying about the entire group being taken to the cleaners. The group leaves the Super Bowl party, horse races, etc with just as much money as went in (minus tickets, food/drink, etc).

I think you have to define what you mean by "less concerned." I'll take a stab at it, which is that Chinese energy use has grown 7% while US energy use has remained roughly flat. The reason I say that this only works because you devalue Chinese lives, is because Chinese energy use remains less than half (possibly even less than 1/3rd by some measures) what it is in the US per person. If the US reduced energy usage by 10% and China's grew by another 10%, it would still be the case that Chinese people relatively speaking are living in conditions that we in the US would consider extreme hardship, as a direct result of having less energy.

Essentially you're saying that the US should bully the Chinese people into increasing hardship because it's the only way to meet our climate goals.

Around 90% of the maps currently on the site are from the US government (USGS). The last 10% are from public institutions and libraries and this is the newest segment that I'm actively working on growing. My hope is to flip this ratio with time.

I also have a few partnerships in the work with some private collections but those have proven trickier to actually get to a "yes". It also involves a lot of bespoke work to process and ingest each individual source so I'm not focusing as hard on this type of sourcing anymore.

So, if a person is a traditionalist/conservative Orthodox Jew, who holds traditional “non-affirming” views on LGBT issues-do those views count as “eliminationist rhetoric”?

If a project decides it won’t welcome people who believe what almost all conservative/traditionalist Orthodox Jews believe (even if they keep those beliefs to themselves in project forums), it is essentially deciding that Jews (of that kind) aren’t welcome-isn’t that antisemitic, and in itself a species of eliminationism? (not with respect to Jews in general, rather with respect to Jews of that kind)

And the same point holds for “Sunni” or “Shi’a” or “Catholic” or “Protestant” or “Eastern Orthodox”

While the Alto and Dorado weren't microprocessors, a couple of years after the Dorado they could have been. And there was a period of time when RISC processors were wasting their potential advantage of running user code at microcode-like one-cycle-per-instruction speeds by not including any instruction cache, as Alan Kay has argued on Quora. If Chuck Thacker had gone to work at Motorola or National and gotten free rein to build a Dorado microprocessor, it would have kicked butt. Also, Superman would beat Spider-Man.

But Xerox wasn't organized to sell even microcomputers, much less microprocessors, so it would have had to be another company that did it. Motorola, say, or Apple, but although they flirted with doing their own processor for the Lisa, they didn't do it in real life until maybe the Mac M1. (PowerPC and Newton ARM weren't really Apple designs.)

The Scheme chip is pretty different from the Dorado or from the Symbolics processors, which at the time also weren't microprocessors. But I think it's a mistake to think they had nothing to do with each other.
