The government can't solve for everything at all times. That's why free markets exist and are important. You could have the best most awesome helmet safety regulation get passed on Friday and have it completely blown up by a new discovery on Monday. How long will it take for regulators to catch up?

> The way you fix that is by fixing regulatory processes

Well, that kinda hand waves away a lot of the roadblocks you run into with government and elected officials. In an ideal world, yes, we have regulatory and legislative bodies that can react quickly and do the right thing everytime but that isn't reality.

FOSS means a lot less than it used to in Android.

Can you download, build, and install a basic Android system these days without touching a single piece of closed code? Absolutely. Will it be able to do much without closed binaries? No.

Android isn't GNU/Linux where there's a general ethos of making everything in userland FOSS if at all possible. Rather, it's a free OS that both Google and manufacturers can do anything they want with, including shove a ton of spy and bloatware on it, then make it to where you can't get rid of those things, at least not easily.

The optimism from 15 years ago surrounding FOSS in the mobile space is on its deathbed.

The IRA were literally blowing up shopping centres around the time their speech was restricted (not banned) on national TV. Sinn Fein mps were elected because of our weird fptp system and the extreme concentration of nationalist voting blocks.

I didn’t agree with banning Gerry Adam’s voice and had sympathy with the nationalist cause, but let’s not make out like these were mainstream figures. Adam’s and McGuinness were apologists for people waging war against the British state. I strongly suspect a communist group with similar aims would get short shrift in the US.

Free speech is never absolute. Europe and the US have different mechanisms to protect free expression, but net they don’t end up in very different places.

I don't know about Wildberger specifically, but an interesting point is that only a countable subset of real numbers can be described like that. Polynomials with integers coefficients are countable and so are their roots, which means almost all real numbers are transcendental.

We think we study the real numbers but it seems we can't even have a system to express them. And indeed, that's not even a limitation of algebraic systems: any notation over a finite alphabet can only express a countable set of distinct objects which amounts to nothing when real numbers are concerned.

I'm not a finitist, but I do find it curious that we approach mathematics by inventing a more-than-infinite set of objects that's impossible to fully grasp. I don't see it as a bad thing though, I also love Complex Analysis and many people (and some mathematicians even) denounce them for being imaginary. My impression is that transcendental numbers are as imaginary as are imaginary numbers, it's just we don't notice. And they're obviously still useful as are the complex numbers.

Good luck to you and I don't have much to add except I am a gentleman over 60 who will be starting a new company within the next year.

This is not very common either but the growth potential is actually so much better than when I was younger and less experienced. It's possible to stack all the cards in that direction for more decades than many high-performers have even been alive, much less adults.

Sounds like you have a good media plan and it may take longer to round up the critical mass of ladies so the media sessions may need to stand the test of time more than expected. I would want lots of excess footage and hold onto it, to enable later crafting the shorts to be as engaging and complementary to newer eventual participants too. Also maybe want to have a differently edited offering a year later to extend appeal in an unforeseen direction.

You may need to reach out to women who are actually grandmas but are not 55 yet, that's a lot of ambition right there. Or go far afield for some non-digital businesswomen especially if their story is inspiring or dazzling in such a way that really keeps people interested.

Now something that not everybody is ready for is how does a company started after "retirement" stack up to a bright young startup with many more decades ahead of them?

For one thing it's going to happen a lot faster plus be order(s) of magnitude less risk. Senior citizens have had enough time to work this out so that partners do way better than they would when younger.

Multiple Environments that can be passed in the email api, per env the delivery config can be defined.

It makes it quite nice to build platforms, have staging systems deliver the same mails to a sandbox, and then in production seamless start to deliver via any smtp server.

I built it from my own needs and because I was annoyed by platforms like sendgrid.

There are a lot of times where I'd say a business should be allowed to fail - but this is a poor choice to do so.

* You can't just spin up leading edge semiconductor manufacturing on a dime. It takes decades and hundreds of billions to reach where companies like Intel and TSMC are now. It's so hard that it's essentially impossible for new entrants to catch up.

* The US has a strong interest in having local manufacturing, that no other power could take away in a time where it's needed.

>a lot of those companies are currently fabless, but how many would change that with equipment bought at a fraction of the cost?

Zero. Dumping the fabs on them would not help them. They're expensive and complicated to run. They don't have the knowledge to run the fab side of design (it's a joint effort on both sides to design a chip), nor the money or knowledge to improve those fabs and keep them up with the leading edge.

> Also, legit callers should keep in mind

Also, legit callers should keep in mind that using a screening service (like Google's) should mean "I'm looking at my phone but you're calling from an unknown number so why do you expect me to pick it up in a world where literally everyone knows how common spam calls are?"

As well as "If you leave a message there's a decent chance I'm going to call you back in 30 seconds, I don't want to start a game of phone tag."

If I don't know your number AND I'm not expecting a call, I 100% will not answer it. If you're legit, sorry, you are the exception, not the typical case. Don't blame me, blame the spammers.

The modern world is absolutely infuriating, filled with self-inflicted problems.

> Right after SHAKEN/STIR was passed

It has definitely gone through ebbs and flows. Predictably around legislation about this topic. I 100% believe this is a problem that can be solved (greatly impacted) through legislation given this strong correlation. But I don't think it is because the DNC list is a list to call but rather that I've had this number for a few decades and it definitely made it onto some list years ago.

> moonlight as spammers

This is 100% happening. As well as a lot of other illegal stuff. I worked at a call center for two months between my undergrad and getting hired and my coked up bosses 100% asked us to do illegal things. I disobeyed. Anytime someone asked me to take them off the list I complied. Got written up, didn't give a fuck. They were definitely selling those lists to spammers who were happy to have confirmation that the numbers were legitimate.

Math in general needs to have a big blinking "don't confuse the map for the territory" label on it.

E.g. when you calculate the area of a plot of land do you take into account the curvature of the Earth? You have to make a bunch of compromises in the first place to even talk about what the area of a plot land means.

Math is a bunch of useful systems that we humans have devised. We tend to gravitate towards the ones that help us describe and predict things in the real world.

But there is plenty of math which doesn't do either. It's just as real as the math that does.

"Who uses versioning numbers like that?" Some coders obsessed with math, among others: Linux kernel: 2.4.0 (1999), Apache HTTP Server: 1.3.34 (2002) etc.

"I've never think about LLMs providers like a cloud provider. I can jump providers whenever I want. I jumped from OpenAI to Anthropic to Open router. Given the parity of tooling and quality of SOTA models I fail to see where the vendor lock is."

You didn't really read the article. You may jump but not your data, not the price and not the dependency. So yes they are a provider and a cloud, while with HugstonOne, the user becomes the provider.

And for the rest, I see you are very curious and have many questions. Maybe you can try the app, I am sure it will satisfy all your questions in an excellent manner.

Our middle school 7th grade civics classes taught us a heavily simplified version of civics suitable for 7th graders. The canonical story of how legislation works bears no resemblance to, for example, the process around NAFTA when some of us were in 7th grade - Congress was not invited to participate in negotiations nor permitted to substantially amend the agreement.

Using tariffs is A common way to protect local industry. However it is a dangerous weapon, which has downsides. In history tariffs have show to lead to high prices on the domestic market and products which are subpar to globally standards. Domestic companies don't have pressure to innovate, while global market has more competition.

Consequence of that is protection by product group for key products one wants to have locally and not per origin on all kinds of goods.

This can lead to short term wins, but backfire after a while.

Does anyone have recommendation for a mini PC with min 2 sata ports for two 3.5” HDDs, min 2 NVMe for ssd storage, one ssd or eMMC for OS, and 64GB of RAM, with the ability to power up the HDDs from the miniPC (not requiring external power source)?

The HDDs are installed in a case externally. An external PCIe slot to support those 4 mixed drives via an adapter would work too. I tend to avoid usb HDDs enclosures, since usb connection doesn’t work well with ZFS.

That would be a cool ZFS NAS.

An eventual output of a calculation has to be a finite result, but the concepts that we use to get there are often not.

The standard way of setting up calculus involves continous magnitudes, hence irrational quantities, and obviously that's used all over physics and there doesn't seem to be a problem with it.

I think to make a compelling case for a finitist foundation for maths you would at the least have to construct all of the physically useful maths on a finitist basis.

Even if you did that, you should show somehwere this finitist foundation disagrees with the results obtained by the standard foundation, otherwise there's no reason to think the standard foundation is in error.

I've never done DC ops, but I bet fan failure is a factor too— basically there'd be a benefit to centralizing all the cooling for N racks in 2-3 large redundant pumps rather than having each node bringing its own battalion of fans that are all going to individually fail in a bell curve centered on 30k hours of operation, with each failure knocking out the system and requiring hands-on maintenance.

I really can't help but think there might be a fundamental problem here. If heat loss in dirt is so incredibly slow, and we use a heat pump to extract that heat, then wouldn't it be equally slow to replace the heat extracted? (absent heat injection, i.e. reversing the heat pump's operation in summer)

Has anyone looked at the subsurface ground temperatures after days, weeks, months, even years of heat pump operation?

I do seem to remember seeing one article on the subject showing that after one winter the subsurface temperature had declined enough to materially affect the heat pump's COP. But the timescale didn't extend to multiple years.

edit: found this one: https://pangea.stanford.edu/ERE/db/GeoConf/papers/SGW/2024/M...

In one of eight cases studied where heat flow is unidirectional (cooling load only) over a 20 year timescale the authors find:

"the mean ground temperature ... increased from 21.87 °C to 26.18 °C, ... . This significant rise could have a potential impact on the performance of the system in the later years of its operational life."

The other 7 cases showed weaker or negligible long term variation.

An additional graph shows COP variation over 15 years and the worst case shows a decline of perhaps 10% (just eyeballing it).

Surprisingly, some cases showed a long term improvement in heating COP - presumably the injection of summer heat into the soil made for warmer soil than just sunshine and natural diffusion?

So my takeaway: "it depends." :-)

We live in the present, so I'd expect it to be overrepresented. I expect most people don't give their kids more money than they spend on themselves, for instance.

Your second sentence showcases some wildly negative biases. I suspect we could probably save money by improving the efficiency of our social programs and end up with even more to spend on scientific advancement.

Those tasks they are measuring are extremely well-defined problems that are extremely well-known. They don't really represent general programming as it is practiced day to day. "Find a fact on the web", "Train a classifier" these are trivial things given the answers are all over the place on Github, etc.

So they're getting exponentially better are doing some easy fraction of programming work. But this would be like self-driving cars getting exponentially better at driving on very safe, easy roads, with absolutely no measurement towards something like chaotic streets, or rural back-roads, or edge cases like a semi swerving or weird reflections.

You're blaming the wrong economist. Keynes believed that trade deficits are a big problem and tariffs are an effective policy to remediate them.

[bri3d pointed out that I missed an element of this. There is a transfer between rack level and machine level coolant which makes this far less novel than I had initially understood. See their direct comment to this]

I posed this further down in a reply-to-a-reply but I should call it out a little closer to the top: The innovation here is not “we are using water for cooling”. The innovation here is that they are direct cooling the servers with chillers that are outside of the facility. Most mainframes will use water cooling to get the heat from the core out to the edges where traditional where it can be picked up by the typical heatsink/cooling fans. Even home PCs do this by moving the heat to a reservoir that can be more effectively cooled.

What Google is doing is using the huge chillers that would normally be cooling the air in the facility to cool water which is directly pumped into every server. The return water is then cooled in the chiller tower. This eliminates ANY air based transfer besides the chiller tower. This is one being done a server or a rack.. its being done on the whole data center all at once.

I am super curious how they handle things like chiller maintenance or pump failures. I am sure they have redundancy but the system for that has to be super impressive because it can’t be offline long before you experience hardware failure!

[Edit: It was pointed out in another comment that AWS is doing this as well and honestly their pictures make it way clearer what is happening: https://www.aboutamazon.com/news/aws/aws-liquid-cooling-data...]

First was staff travel, then annual and monthly travel adds, then Prepay (later PAYG) on the tube, then bus, then overground, then later suburban trains.

If you had a z1-3 travelcard you could travel to zone 6 with Prepay as long as you had a positive credit and would have the allroaite fare deducted. For travel on train you had to buy an “extension ticket” though. That I think might have extended even past payg availability on trains for a while.

It’s amazing in hindsight how quickly things changed, but I remember the various messes were quite notable for the first 10 years of oysters existence.

I'm just keying off this thing you wrote:

For example, the suicide was very poorly handled. It was used as vehicle for discussing open source vs proprietary code. But you could have easily done that without the death [...]

It's totally fine if we're not making any productive progress in this part of the thread. It's art, it's all subjective, we can just disagree. I think the interpersonal dramas in HACF are as earned as they are in any series; certainly, I'd put every season of HACF several notches above Six Feet Under Season 4 and its Scooby-Doo finale.

At the same time, I don't think there's any kind of important broader theme or message or ideas in HACF; the A-tier of prestige dramas have that --- The Wire, Mad Men, Better Call Saul. Mad Men and The Americans are I think the best comparands; both period shows with high-concept settings, both bigger idea/theme shows than HACF.

Somehow, DHH has tapped into an enthusiasm for Linux I haven't felt in a long time. It's so great to see and to experience it with him! When I first discovered Linux it started a journey, from wonder to pragmatism (Mandrake [2004] -> Slackware -> Ubuntu -> Arch -> NixOS [current]).

I also spend many nights tweaking and re-tweaking, compiling kernels to get the maximum out of my desktops on rotating cubes with reflections and fish inside, the early Beryl/Xgl days. I miss those days, but Linux is a tool now, sometimes even just a runtime! Still have it on any computer though, and it just works, it feels like home!

From that late 2.4 kernel, manually mounting the first USB drives to what we have now. Super slick and smooth desktops, COW files systems, the ability to run almost any software. I love Linux.

Video drivers & hardware are a plague on both Windows and Linux. Hell, adding a discrete video card to the config was even a way to increase your odds of serious problems with a Mac by a large multiple, back in the Intel Mac days. Any complaint-session online by Mac owners tended to be dominated by folks rocking non-Intel video chips in their MacBook.

“ The FCC is doing everything in its power to fight back against these malicious and illegal calls.”

Umm, no it isn’t. This is 2025. The technology to fix this is not complicated, but the people who can implement it simply don’t want to.

If Verizon/ATT/T Mo got fined $25 every time a robo call went through they’d find a way to stop it really fast. Create KYC verification systems and use metadata to route non-verified calls to a spam voicemail folder, problem solved.

Just to adjust the numbers a little, the Pi idles at 2-4W (for similar RAM spec), and the N100/150 are only about 2-4x more performant (with a slight bit less efficiency), for most tasks, in real-world benchmarks.

(Not saying they're not a good value, but you'd have to cherry pick a few benchmarks to say there's 4-10x performance.)

> I mean, in my life i probably spent hundreds of hours writing code and hacking things together - forcing them to work - for tasks that turned out to be...already solved, I just couldn't find it...it was under the sun all along.

Once you get older it gets even more annoying - sometimes you end up solving a problem, and later on you realize (or, even worse, a friend points it out) that you've solved that already once before a decade ago _and_ published your solution back then.
