Interesting idea. 2km deep could work. I'm not sure how cooling or maintenance would work.

Depth below surface | Typical temperature (°C) | Indicative cost to drill 1.2 m diameter hole

500 m | 15–25 | $5–10 million

1 km | 25–40 | $10–20 million

2 km | 50–70 | $25–45 million

3 km | 75–100 | $50–80 million

4 km | 100–130 | $90–140 million

5 km | 130–160 | $150–250 million

1) The makers of this plugin are from EFF, and thus have the time and resources to combat litigation.

2) Yep! And as mentioned in other threads, it would give the users on their ad platform more money but degrade the quality of their ad platform.

I was just alarmed by how many people are not only okay with, but defending, the current state of ad tech. I think it's a noble effort to go against the grain and withstand any potential legal trouble to subvert it as it seems there's no recourse to be made in the courts unless an entity has the aforementioned time and money to fight it in the courts.

Put a script in /etc/systemd/system-generators/ that does something like

if grep "logging = syslog" /etc/stupid-service/stupid-service.conf >/dev/null; then
printf "[Unit]\nAfter=rsyslogd.service\n" > "$1/stupid-service.d/10-syslog-dep.conf";
fi;

> It's pretty basic and straightforward

Postgres config supports line continuations, so the OpenRC service file you quoted is buggy; it could potentially match a file just because some other option contained a multi-line value that had the string "log_destination = syslog" in it.

The whole philosophy of systemd is to move away from these kinds of "simple" and "mostly working" pile-of-shell-script systems to actually-unconditionally-correct configuration that doesn't come with bonus text processing surprises.

I want to nitpick you here but a thermos is specifically good at insulating because not only does it have a vacuum gap, it's also got two layers of metal (inner and outer) to absorb and reflect thermal radiation.

That specific aspect is NOT true in space because there's nothing stopping thermal radiation.

Now you're correct that you can't remove heat by conduction or convection in space, but it's not that hard to radiate away energy in space. In fact rocket engine nozzle extensions of rocket upper stages depend on thermal radiation to avoid melting. They glow cherry red and emit a lot of energy.

By Stefan–Boltzmann law, thermal radiation goes up with temperature to the 4th power. If you use a coolant that lets your radiator glow you can conduct heat away very efficiently. This is generally problematic to do on Earth because of the danger of such a thing and also because such heat would cause significant chemical reactions of the radiator with our corrosive oxygen atmosphere.

Even without making them super hot, there's already significant energy density on SpaceX's satellites. They're at around 75 kW of energy generation that needs to be radiated away.

And on your final statement, hyperloop was not used as a "distraction" as he never even funded it. He had been talking about it for years and years until fanboys on twitter finally talked him into releasing that hastily put together white paper. The various hyperloop companies out there never had any investment from him.

As much as people are trying to find a standard for agents as a platform or a winner take all, the area itself is still growing and emerging.

The source of it is instructions, most often in text.

Managing how that text relates to the journey of the ultimate result is a new area, while there are pockets of helpful tools and libraries, their relevance can come and go quickly as models can improve just as fast, sometimes maybe even taking inspiration from what the community is working on and then adding that capability to the model.

I had to do some research to figure out what this is actually doing. When you try to pass e.g. strings through WASM functions you end up writing the data to memory and passing offset / length, which is obviously inconvenient and potentially has security implications. WASM components [1] is a spec that tries to improve on this with an IDL called WIT that lets you define functions that pass complex types with a proper ABI.

This all seems sensible for languages like C or Zig that neatly cross compile to WASM. But I was very confused how this could ever work with a duck-typed interpreted language like Python, so I did some digging.

Apparently "run your Python as WASM" part is implemented by componentize-py which cross compiles CPython to WASM as libpython3.14.so [2].

I'm not sure whether I should be impressed or horrified...

Assuming that we place an iron ball (ideal sphere-shaped and thermal conductivity) on the SSO (solar synchronous orbit), how hot can the object be?

Given the solar constant 1361 W/m^2, you can calculate the temperature range based on the emissivity and absorptivity. With the right shape and “color”, the equilibrium temperature can be cooler than most people thought.

I suppose that a space data center powered 100% by solar is no different than this iron ball in principle.

It's actually a crime for unauthorized officials to negotiate with countries directly to influence disputes, under the Logan act.

Going backdoor with Denmark to make "unrelated agreements" (wink-wink) at the same time as the Greenland dispute is just a cheap way to get around that.

* Note that this doesn't mean I agree with the Logan act, but it's pretty obvious what is happening.

The Nova framework for classifying processed foods was created in 2009 by a Brazilian epidemiologist

https://en.wikipedia.org/wiki/Nova_classification

Presumably, since the first citation in the paper is said epidemiologist (Monteiro), this is the framework they rely on.

Unless you’re intent on scientific gatekeeping, in which case having actually read the reported study (it’s linked in the article fyi) would have offered much more effective methods of rebuttal than semantic quibbles.

You are entirely right, because 98%+ trips in a car are commutes or errands that average 6 miles in distance.

But, that is not the topic of conversation above -- we were talking about trips 600+ miles in distance. These are almost exclusively not commutes.

Averages don't necessarily describe your whole data set. Just like how the average person has around 1 testicle, this data is also multimodal :) ... People commute alone, but they go on vacation with friends/family.

Yes, I've begun translating "ultra-processed foods" to "junk food". It's roughly the same meaning and roughly the same amount of scientific rigor. UPF sounds scientific and specific but it's neither.

OTOH everybody intuitively understands junk food is bad for you, has a rough idea of what it is and that the definition is circular.

I'm also on a M1 Macbook Pro, running Tahoe 26.2.

Not sure why yours is so much slower than mine. Mine is definitely 250 ms long or 15 frames from the time I hit the shortcut.

I used the onscreen keyboard viewer to get visual feedback when the shortcut was pressed and recorded audio so I could hear it being pressed. I even recorded it a second time using OBS to ensure I was at 60 fps and trimmed the whole segment down to just the animation and sure enough, the video is exactly 250 ms long according to IINA.

Also, I don't have any visible delay between pressing the key and the animation starting. The animation starts on the same frame as when the shortcut is recognized by the onscreen keyboard viewer (which is the same time as I hear it being pressed) in the recording. The keyboard delay must be < 16.6 ms.

None of what you said is true.

> the federal Gun Control Act of 1968, which gives you the right to manufacture a fire arm

There has been a right to manufacture firearms since before the Revolutionary War, and which has remained a right continually since.

> it must be for personal use

Not necessarily; though you can't conduct business without a federal license, you can, for example, manufacture a firearm to be given as a gift.

> cannot be transferred

See above.

>must have a serial number

Not only is that not true, a federal judge struck down the prohibition on defacing serial numbers in United States v. Randy Price (2022):

Measles is popping up in numerous countries the last couple years. Canada has way more cases than the US in absolute numbers and it's catastrophic per capita.

It'd be great to start digging into the "why" and figure out how to mitigate the sources.

> Canada has seen an alarming increase in the number of measles cases since the outbreak began in October 2024, with a total of 5,380 probable and confirmed cases as of Jan. 10, according to Health Canada.

Ref: https://www.cbc.ca/news/canada/manitoba/measles-manitoba-18-...

> In recent months, six countries in the World Health Organization’s (WHO’s) European region that had previously eliminated the disease have officially lost their measles-free status. In other countries, measles is once again considered endemic.

> Although the decision to remove these countries’ measles-free status was taken last September based on 2024 data, the World Health Organization (WHO) did not release the information publicly until this week, once all countries had signed off.

A thought experiment. Imagine that you had some magic way of getting all the electricity you wanted at the south pole, you had good internet connectivity, and the various treaties about the place weren't an issue for you. Would you want to build a data center there?

Seems like a pretty obvious "no" to me. Loudoun County is a much better choice, just to pick one alternative. Antarctica is an awfully inhospitable place and running a data center there would be a nightmare.

And yet it's way better than space. It's much easier to get to. Cooling is about a thousand times easier. The radiation environment is much more forgiving.

This whole concept is baffling to me.

(Incidentally, a similar thought experiment is useful when talking about colonizing Mars. Think about colonizing the south pole. Mars is a harsher environment in just about every way, so take the difficulties of colonizing the south pole and multiply them.)

I'm no fan of the current US administration, however I have questions about this.

What currency controls have been implemented? A cursory search turns up no results, though there is some speculation that capital controls could be coming, they never the less haven't materialized, at least in such a way that no credible news outlet has plainly stated it.

The debasing of the USD is again, a fear, and Trump is absolutely stoking the fire around it, but it hasn't actually happened, as far as I can tell.

If you have evidence of the contrary to either of these I'm quite curious to see it. I wouldn't put it past this administration in the slightest, but there is a difference between implementing them and talking about them and for correctness sake I want to understand.

Agreed. I hope these terms go away. I think what people tend to mean is "calorie dense, low in nutrients, low in fiber", or something along those lines, and the term "processed" makes it far more confusing.

"Processed" ends up meaning anything from "high in sugar" to "long shelf life" or "one of a dozen kinds of artificial sweetener" etc. It does more harm than good.

I can have an extremely high fiber, high protein, nutritionally well rounded meal that's also "ultra processed".

Someone mentioned Nova. Nova is a PERFECT example of how god awful the term is. When asked to classify foods into Nova categories there is almost no agreement amongst nutritionists.

https://www.nature.com/articles/s41430-022-01099-1

Time after time, Nova is shown to be more confusing than helpful, with worse than random results. Nova itself doesn't even attempt to correlate with "healthy".

The meaning of kilo, mega, giga, tera, etc. are unambiguous: SI prefixes defined as powers of 10, not 2. 1 TB is 10*12 bytes, not 2*40 bytes.

The misuse of those prefixes as powers of 1024, while useful as shorthand for computer memory where binary addressing means, is still exactly that: a misuse of SI prefixes.

There's now a separate set of base-2 prefixes to solve this, and people need to update their language accordingly.

Ok, but how about learn why that is instead of just insulting half the population. In politics, it is best to be liked and quoting such things doesn't help.

Now, why is literacy so low? Because we stopped teaching phonics in schools. When we switch back (in tests/experiments) phonics wins hands down. When we did teach phonics, we had the highest test scores in the world (now we are 17th or so). Who opposes switching back to phonics? Oddly the teacher's unions. Guess who is the biggest contributor to the Dems? Weirdly it makes sense when you frame it this way. Now, ask yourself why you didn't know this?

Also, if I wanted to print a gun, there are thousands upon thousands of older Creality and Prusa printers that I could buy used. My CR-10 isn't connected to the internet, it's running a FOSS Marlin release.

It will be very strange and funny if there is a registry of 3D printers before there's a registry of guns, and for that matter, it will be very funny if it becomes easier to buy a gun than a 3D printer, with the reasoning being that 3D printers can print guns.

I am afraid that gatekeeping is partially essential and somewhat desired, as an academic you don't have time to read everything and some sort of quick signals, albeit very flawed, can be useful to stop wasting time reading crappy science. If you don't gatekeep you will get a lot of crappy papers or papers that mention the same thing and it will waste more time from people that wish to get a quick sense of the state of a topic/field from quality work. An open source voting system would be easily abused, so it will end up to be trusting a select service of peer reviewers or agencies. Especially if a paper includes a lot of experiments and figures that can be somewhat complicated or overwhelming. What do think?

> Nobody saw this coming.

That simply isn't true. Here's a PDF from December 2024 (before Trump was elected) by the US Senate Joint Economic Committee:

https://www.jec.senate.gov/public/_cache/files/5c392e02-9eb0...

Throughout 2024, Donald Trump has proposed a series of tariffs on all goods coming from outside the U.S. or on goods from specific countries. His recent proposals include:

• An across-the-board 10 percent tariff on all products imported from other countries.

• An across-the-board 20 percent tariff on all products imported from other countries.

• A 60 percent tariff—“or higher”—on all goods imported from China.

• An additional 10% above any additional tariffs on imports from China.

• A 25% tariff on products imported to the United States from Mexico and Canada.

Yes, everbody who was paying any attention at all saw this coming.

Of course it's working. We've had computers operating in space for decades. There's no doubt it can be done.

The question isn't whether it's possible, the question is why you'd do it just for data centers. We put computers in space because they're needed to do things that can only be done from there. Data centers work just fine on the ground. What's so great about data centers in space that makes them worth the immense cost and difficulty.

I know a lot of prominent people are talking about this. I do not understand it. pg says "when you look at the tradeoffs" well what exactly is he looking at? Because when I look at the tradeoffs, the whole concept makes no damned sense. Sure, you can put a bunch of GPUs in space. But why would you do that when you can put them in a building for orders of magnitude less money?

> The only few places where binary prefixes are used are to refer to RAM capacity and file sizes, whereas decimal prefixes apply to all other areas and all units (not "only bitrates"): storage capacity, clock frequency, stream bandwidth, baud, pixel numbers, data throughput, processing power

Storage capacity also uses binary prefixes. The distinction here isn't that file sizes are reported in binary numbers and storage capacity is reported in decimal numbers. It's that software uses binary numbers and hard drive manufacturers use decimal numbers. You don't see df reporting files in binary units and capacities in decimal units.

Of that large list of measurements, only bandwidth is measured in bytes, making the argument mostly an exercise in sophistry. You can't convince anyone that KB means 1000 bytes by arguing that kHz means 1000 Hz.

It's not gatekeeping to point out that multiple studies have shown that Nova is a perfect example of "no one agrees on what processed foods are". Even when given Nova criteria, nutritionists repeatedly, across studies, fail to agree on categorization.

Nova also does not even attempt to categorize in terms of health because "processed" has nothing to do with "healthy" despite being used in conversations about public health. Absolutely perfect example of how bad the term "processed" is.

Yes - since the framework itself is open-source, you are free to take it and run anywhere you'd like. Of course, the experience is much better if you run on Modelence Cloud since it's zero config and also gives you the dashboards / UI to manage everything out of the box. But ultimately there is no lock-in whatsoever, you could even fork the framework repo and modify it as you wish.

This is like arguing astronomy isn’t real because colloquial definitions of space are ambiguous.

The study [1] uses a definition that finds a significant effect. We should investigate that further. If it pans out and the term ultra-processed food triggers people, we can rebrand it. (Did the cigarette lobby ever try muddying the water on what cigarettes are?)

I just looked up what it was and I heard people talk about it. I realized I was doing something close without realizing it.

Every new project (cloud consulting + app dev), I feed in the contract, transcripts of my discovery sessions, my labeled architecture diagram, transcript of the design review discussion, any other artifacts.

First I have to create Epics and stories anyway for the PMO even if I am working on it by myself.

Then I ask ChatGPT what the phases should be, I tweak it , break it down, give it more details, etc

Finally, I ask it to give me unrendered markdown with the details and a checklist.

As I’m using Codex (I never seem to hit limits with my $20 a month plan) and Claude (better at troubleshooting), I tell them to update my document with what’s done, guidance I’ve giving it etc.

I treat both of them like junior devs and keep my hands on the wheel and test and verify each phase.

Your position is fantastic because it immediately puts to death all of that nationalistic nonsense about the EU becoming "anti-American" by enforcing privacy laws on US Big Tech etc, when in fact they are just protecting their citizens' rights against unethical business models regardless of origin. I might be naive, but your company to me represents a win for free/open software and cross-country collaboration.

That being said, I should ask: to what extent do you see being US-based an advantage or a problem in the current state of things? For example, in regards to exports controls, or any other such thing that may potentially limit your business scope depending on $current_admin.

That chart is telling about the durability of this business, but do we actually know the precise point at which YCombinator as an entity sold out?

For instance, I know Coinbase may be down -22% from the IPO price, but that doesn't mean YCombinator lost money nor made very little. If they, for instance, sold off during the first few days of the IPO they would have made out quite well.

There's also the whole question of how much money did YCombinator put in vs what they got out.

Without knowing this, about all the chart tells me is YCombinator is not a predicated on building exceedingly durable businesses, but it doesn't mean they lost money on any of these investments either.
