Thanks for the link! I wonder how this works. Is there just no practical impact of the "book value" being so far off the market price? Surely any exchange is done at the prevailing rates.

> The market value of a gold bar depends on its weight, purity level, and the prevailing market price for gold. Rather than market pricing which fluctuates daily, the New York Fed uses the United States official book value of $42.2222 per troy ounce for gold holdings.

There was a point before search engines of course. And, there was a point before people outside of, say a university, had any real Internet access.

But via my personal experiences in the late 90s, I recall search engines working just fine (eg, Alta Vista) then slowly degrading, then one day they were just completely useless. I mean, any search term would just returned page after page of spammy links. You could find nothing, ever.

There was Yahoo's curated list, with lots of volunteers keeping it going, but it had dead links, and was always a tiny tiny fraction of what was out there.

Just a few years later Google appeared, which at the time was absolutely gob smacking insanely good. It was no contest. Yet even this nascent google didn't have a large portion of the web, I remember people trying to get their links on larger sites so Google could find them. I think Google even had a submit link page too? Not sure when that appeared.

So I can imagine in this time period, someone might have had a list of links they found and spread by email. I remember using the 'bookmark' function of my browser a lot, it was easier than searching.

>This is not the same issue you are talking about.

You're right, car repairability is an even bigger issue than phones.

>Cars are repairable, phones are not

New cars are repairable only by the authorized dealer, with authorize parts and tools, and those parts are maliciously engineered as modules where for a 2$ defective connector the dealer will replace a 1000$ module and electrical harness because they don't sell the 2$ connector separately, they sell the whole thing as a module/kit. How is that not anti consumer and anti environment?

If my phone breaks and can't easily fix it, I can buy a new one for 200$, or keep my old one as a backup until I figure out something. Meanwhile if my car breaks, I can't buy a new car on a whim, and most people also can't afford to keep a backup car around.

This is a WAY bigger issues than non repairable phones. A defective car is a much bigger household expense than a broken smartphone.

> I was asking what they meant by that. I did not disagree with right to repair.

You could have looked it up. It is a common expression.

> To the contrary -- IMO vehicles must be completely repairable with freely available standardized general purpose parts, as opposed to pre-made custom assemblies at ungodly prices and limited production periods.

They already kinda use standardised parts. Most manufacturers license parts from one another e.g. I have a Vauxhall, the chassis IIRC is the same as a Volvo. Super cars will have headlights from a Ford Focus.

My Land-rover Defender 4x4 uses the same parts are other British Leyland cars of the same period e.g. the wiper system is the same as one on a Rover from the 1980s, the engine mounts are the same as the ones used in a Rover P4 from 1953.

More modern cars and electric cars though need entire custom drive chains, electronic wiring, sensors and computer system that are not standard.

> Removing emissions functionality (which I explicitly listed), or safety functionality is not repairing your vehicle, it is altering your vehicle to your own benefit and at the expense of everyone else, and must be prevented by the government, and not by auto manufacturers.

Making your car un-roadworthy is already illegal. That is why yearly safety inspections (MOT) are required in the UK for any car that has been on the road for more than 3 years. If your car has obvious emissions issues you will be pulled over by the police.

> I thought this was implied with 'being frowned upon', because society and their government representatives frown upon stuff, auto manufacturers outright prevent it.

They already try to prevent it. Newer cars will detect this and may even refuse to start. It however like any restriction. It can be circumvented.

My impression is that mojo is not python, there are similarities, but under the hood mojo is much more similar to c++/rust.

As part of this it has a stronger type/lifecycle/memory model than python.

Maybe you could write, some level of transpiler, but so much of the optimizations rely on things that python does not expose (types), and there are things that python can do that are not supported.

A system that naturally occurs as a result of the context like you describe sure sounds like a superstructure. Which in our case is a government that allows anyone with the money to steer the ship while actual people have little power to change anything. And when you put enough of those people with money in a room with people who take money and give them laws, it absolutely results in a single unified direction for that system. Of course there are disenters, but they are ineffective compared to those with actual power.

It's easy to say but not so easy to do.

The two Western designs built in the last generation are the EPR and the AP1000. The EPR is so unconstructable that it could have been designed by Amory Lovins to put the nails in the coffin of nuclear power. The supply chain for the AP1000 is centered in China. If it wasn't for problems of war and peace the rational thing to do might be ask the Russians to come in and built a VVER.

GE is pushing the BWRX300 which might get some cost reductions because it doesn't need a steam generator, but the small size doesn't help the economics and the cost numbers they are talking about are amazingly low.

No, they aren't "all" subject to licensing rules. That's why the specific industries do matter.

Can you share some examples of these doctors? AFAIK the only doctors who lost their licenses are those who created fake medical documentation or who shared verifiably false medical information. Not for "disagreeing" with the government stance on vaccines.

I don't know if you lived in a different timeline than me, but I remember a lively debate throughout the entirety of COVID. Consensus (and evidence) was overwhelmingly on one side, sure, similar to how consensus is that you should go to the hospital if you get a heart attack. And yeah, if a doctor advises someone against that despite strong clinical evidence that the patient is best served by going to the hospital, they'll jeopardize their license.

how our workflow starts changing when we realize it can hold multi step intent. l we stop thinking file by file. we start thinking in actions. "split this module, write tests, refactor callers" becomes a single unit in out head because Claude understands that as a unit too( maximum efforts mode ).

this slowly rewires how we approach code. we stop worrying about syntax early, we write more scaffolds, we batch tasks more. subtle shift but huge long term effect.

how soon before we start designing codebases for LLM agents to navigate more cleanly? flat structures, less indirection, more declarative metadata

Bullshit detectors are a huge part of the problem (and a big part of conspiracy theory methodology). If something is fundamentally true but is also counterintuitive, it will never pass a bullshit detector. On the other hand, a statement that is convincing but is actually false is relatively simple to make and hard to argue against (just ask ChatGPT).

You're making it partisan, I wasn't.

>If something bad happens, every media outlet will blame the party they don't like for it somehow

Ignore the media. If a loved one of yours would be killed by a visa holder who wasn't vetted properly even though his social media profile had all the red flags, who would YOU blame ?

> Responsiveness is important to what purpose and from whose point of view -- yours or your society as a whole?

My needs and the rest of society will be different. So posing every response through this filter is asinine.

Not everyone drives in a city with perfect well maintained roads in a city.

I drive on roads that of full of pot holes, has deep ditches on either side and frequently there maybe obstacles in the road (rocks, trees, animal). I drive under the speed limit normally as the roads can be dangerous.

Having a vehicle that is more responsive/lighter/better visibility is better than something that has bunch of driving aids which are largely useless in such circumstances.

> I've had her (try) to park a car without electric power steering and with a carburetor

Parking a vehicle isn't that difficult and you should have learned to do it properly by the time you take your test.

If you wife can't park a vehicle without driving aids than she shouldn't be driving that vehicle.

That's not the argument and never was. Humans aren't proof that you can't do better than vision, we are proof that the problem can be solved with vision.

This isn't a question of max-sensors vs min-sensors, though. It's a question of max-sensors vs max-data under economics constraints that forbade "why not both?". Tesla chose max-data, and they now have a 40x data advantage thanks to their choice, and probably more once you consider the improved diversity of data collected from private cars in every corner of the country and world.

If you were training a self-driving car, would you rather have 40x the data or would you rather have point clouds that are only a smidgen better than what you can get from modern monocular depth reconstruction on the vision data?

I had to look it up but mark Z Danielewski (author of House of Leaves) is 59 years old, doesn't push back the age very far though. For a 55-year-old they'd be 10 in 1985, I imagine they'd be more influenced by Star Wars, Brazil, and The Breakfast Club, than Her or We and go on to write Severance, Fleabag, or Atlanta than Heart of Darkness or 1984.

Is it critical these days? I am by no means against nuclear energy, and if we had been building reactors these last 50 years the world would be a better place. With things like solar, wind, geo-thermal, etc... is it still smart to invest this much money into nuclear power? Wouldn't it be better to invest in solar at this point?

I resonate with this nostalgia for the early internet, I really do. But lately I've been wondering if the tools available to us now are the key to bringing back what we miss about the old internet.

For example, let's look at "for you page" style algorithms. When I open Reels, I see incredible musicians, mind-blowing visual art and really thoughtful insights from people all over the world. That's exactly what I wanted out of the early internet, and here it is, an ever-evolving system that connects me with all the weird and amazing things that exist out in the world.

And those people in the world who make this content now have an agent actively connecting them with their audience. Yes, I realize this is an extremely charitable interpretation of what's happening behind the scenes. But often, the content I see feels very close to what the author is describing: Someone taking the time to describe their favorite tree.

If there was ever a "good ol' internet", it's still in there. It's just had tons of freeways and high-rise buildings built up around it. The older I get, the more it seems like you just need to let your eyes adjust a bit to see it.

Edited to add: My favorite tree, right now anyway, is a pair of birch trees in a park near my home. When they leaf out and the wind blows, I sit in the grass between them and it sounds almost like I'm at a beach, which is really nice because I'm about as far from an ocean as you can be on this planet.

> I'm claiming that the alleged air superiority is most likely partial and temporary.

This is rich. It took minutes to claim the air over Iran, what exactly gives you the impression of strength? Two US carriers parked off the coast is enough to not only maintain that superiority, but to down the entirety of their very aged air force.

> Iran to protect knowledge of its capability

Let’s think this through. You could announce that you’ve downed an advanced fighter without explaining how and unless the US or Israel gets a hold of the wreckage to do an investigation, nobody but the pilot will know how it was downed. This logic that Iran is trying to protect some super secret method of downing advanced fighters doesn’t pass the smell check.

> The average working American in my state can't afford "good" healthcare but we're happy to let these people in sign these people up for state healthcare and benefits (at least in my blue state, perhaps the red states have stringent criteria that makes them ineligible) and doll out millions of dollars of contracts to all sorts of entities that facilitate this process. It's absolutely nonsensical policy. And this is without even examining the effects on supply and demand of labor, cheap housing, etc, which I'm sure aren't great.

You're blaming the wrong people for this. Illegal immigrants are not to blame for shit healthcare and if anything, they make things cheaper for you. No one in your state wants to work farms for less than minimum wage.

> I don't hate the immigrants. They're mostly fine people. But I would enact the most unspeakable horrors upon the people who actively created this situation were I given the opportunity.

The most conservative voices are the ones who hire illegal immigrants under the table including the current POTUS. Illegal immigration is a solvable issue and if you look closely at Texas government you'll see that. You will occasionally get a Republican who puts forth a real solution for illegal immigration and other Texas Republicans tank it because they like to campaign on the issue. You can't campaign on illegal immigrants if you fix the problem.

Questioning science is not automatically "anti-science," IMO it's best to remain skeptical and stay focused on the evidence. The fact of the matter is that current "best medical advice" is not the best either in terms of quality of life or prognosis. I've had a remote member of a family lose sight in an eye, develop short term memory issues, and rapidly deteriorate from cancer in spite of following the best medical advice and guided by top physicians. My family is full of physicians, and I see even them questioning traditional methods. I would caution against media's rush to blame anything going against the mainstream narrative as "anti-science" or "misinformation." Yes, there are quacks and morons, but let's not put labels on anyone questioning bad outcomes.

Food (and other fuels) are special.

Water largely isn't fundamenally transformed with use (unless it's involved in a chemical reaction, though that's a minute fraction of all water usage), though it may be dispersed or degraded (usually contaminated with something). But it can recover its earlier state with appropriate applications of process and energy. Water (and much else we consume) is a material input rather than an energy input.

With energy inputs it is the energy potential itself which provides value, and that potential is intrinsically consumed in their use. Water, wood, iron, aluminium, lithium, helium, etc., can all be recycled, restored to their useful state, at comparatively little cost.

Collecting the waste products of food don't give you that, on two counts. First, most of the actual metabolic output is gaseous and lost to the atmosphere at large (CO2 and water vapour in your breath), and to the extent that solid and liquid human waste are useful in producing new food, it's a nutrient fertilisers which enable energy conversion of sunlight to fuel, and not the primary energy input itself (sunlight).

If they mutated the real environment it could be even worse, since they're still privileged code and there are all sorts of environment variables that libraries read at runtime using `secure_getenv`.

I finally understand why they're trying to deprecate `pam_env`, despite its incredible utility. For some reason, instead of only applying its contents to the user environment for the child process like any sane person would do, they are trusting its values for the library calls in the privileged parent itself.

Nothing I can share externally at the moment, but I've been using it to almost speed-run through creating a docker compose stack of apps and deploying it on an cloud server. I've had Claude Code write 99% of it (not exaggerating), including app code (mostly in Python), configs, tests (unit, integration and playwright browser tests), deployment scripts and documentation. For this use-case, it's not yet good enough for working fully independently, and I need to steer and course-correct it every once in a while, but it feels a lot more like managing an eager but inexperienced person, rather than a "tool". And while I do make some manual changes every once in a while (particularly in the plan files I have it generate), in the vast majority of cases, I find it more convenient to tell it what to change and have it change it, until I'm happy.

More recently, as I've gained trust in the process, I've also started more and more asking it to manage "subagents" to do some of the lower-level work, and it's been a very valuable power multiplier too, allowing for additional parallelism, without growing the main agent's context.

I was driving myself mad; xterm was released in 1984 and it didn't really matter there was no XDM because there because you merely needed a window manager to tile your xterm windows...

But sure, the definition of "X terminal" here is meant to mean dedicated hardware that runs an X server connecting to a remote X11 display manager, and nothing else. Those were always somewhat niche, in the same way that once terminal emulators existed, general purpose PCs displaced hardware terminals.

In the 1990s, my university used inexpensive diskless X86 PCs running X386 (predecessor of XFree86) with just a ramdisk, booted by DHCP / BOOTP / TFTP.

Nuclear is a very poor complement for solar & wind. To complement solar & wind, you need dispatchable power to supply power while the sun isn't shining and the wind isn't blowing.

Most nuclear plants can't do that, they need to run 24/7. Some can, but they're horrendously inefficient and expensive to run that way.

Smaller scale can make construction more practical though, even if the economics are worse than the theoretical best. Billions have been lost on unfinished large-scale nuke plants more than once, because they take too long, are too complex, and get more and more mired in politics as the years drag out. A small plant that could be online in months or at most a year or two from start of construction is way more pragmatic.

The TRS-80 is what a computer would look like if you only had a CB radio factory to build it. I think they designed it to be cheap enough to do that first production run, but then they were stuck with it since it sold so well.

When they went to Level II basic, they had to fit 3 roms in the space of 2 sockets. No problem, just an add on board. Oops, that board won't fit on the back. We'll tape it to the front and use some long wires. The whole expansion interface part comes across as a total hack.

I get the impression this is what it would have been like if instead of making an Apple II, Jobs and Woz said "well, these keep selling" and just decided to keep hacking away on the Apple I.

There is a nice illustration of a 2-sphere wrapped twice around another 2-sphere on the Wikipedia article for the homotopy groups of spheres [0].

Now, there are many ways of proving that there is only one way (up to homotopy) of wrapping a 2-sphere n times around another 2-sphere, but all of them are fairly involved. The simplest proof comes from an analysis of the Hopf fibration, which roughly describes a relation between the 1-sphere, the 2-sphere and the 3-sphere [1]. Other than this, it follows from the theory of degrees for continuous mappings, or from the Freudenthal suspension theorem and some basic homological computations.

We [1] have been using Typst to generate PDF documents in production for a few months, such as invoices and labels. It's generating thousands of documents daily, and I'm glad that some of them are printed and used by people in the warehouse who are doing real work.

I really like the simple syntax that Typst provides. It would be much harder for the PMs to edit the templates if we went with other solutions, such as wkhtmltopdf.

We also looked into other document generation services that provide a WYSIWYG interface, and they are all quite expensive and often lack advanced scripting capabilities.

The lesson they have learned is that people who care, can tell the difference and shop with them are such a small minority that it isn't worth it to their bottom line to address this. The government doesn't seem to care either. The market isn't going to fix this.

Maybe you can round up enough people for a common cause as discussed in the article, but that doesn't scale. Take notice that for all its talk about America first policy & general sinophobia, the current admin in Washington hasn't done anything about this either. They don't care about American small businesses or consumers. They only care about people like Jeff Bezos, the Waltons, etc.
