> FDR’s New Deal saved the entire planet from a descent into Nazism and Japanese imperial rule

The New Deal delayed the recovery from the Depression to 10 years or so. American industrial power saved the planet from Nazism and Japanese imperial rule.

US industry supplied all the Allies (including the Soviet Union) with large quantities of everything needed to fight with, on a global scale. That had nothing to do with the New Deal.

The Depression ended with the flood of foreign money pouring into the US to buy armaments.

This pisses me off to no end. I paid a lot... I expected my Nest gear to work for as long as I own my house. I paid extra to get someone to install it with my home system. Now I see that my Nest Protect is saying it needs to be changed... not some small module... the whole thing. Next will be my thermostats... I can't understand why I'd pay for them again.

Yann LeCun and others created https://lush.sourceforge.net, which was a Lisp for ML.

It was probably the best option during the 2000s, and only superseded when Theano (Python) and Torch (Lua) emerged.

A Lisp comeback in this niche would be great. Python has fantastic libraries, but the language leaves a lot to be desired.

Most startup tools are dashboards for vanity metrics. Startup Solve isn’t.

It’s an AI-powered co-founder, oracle, and stress-tester all in one — designed to tell you the truth, predict funding chances, and validate ideas before you burn months (or millions).

I built it because I was tired of watching founders drown in noise. It’s not perfect. It’s brutal. And it’s working.

Ask me anything about building it, running it at 14, and why every founder should have one.

This is one of the reasons I am working on an enclosure-compatible open-source version of the 2nd gen Nest thermostat. It reuses the enclosure, encoder ring, display, and mounts of the Nest but replaces the "thinking" part with an open-source PCB that can interact with Home Assistant. Nest has been pretty-badly supported in Home Assistant for over a year anyway, missing important connected features.

I've got the faceplate PCB done and working; the rotary encoder and ring working; and the display working but with terrible code with a low refresh rate.

I need to ship at the end of October to beat the retirement date. Plans to get some regular development report-outs and pre-orders are coming quite soon.

It's open source, and uses ESP32-C6 so it can be Wifi, BLE, or Zigbee, whatever software you intend to load onto it.

I've realized this for myself, based on me getting ~350miles from a ICE per tank, and only filling about once ever 3-4 weeks. It's clear that for like 99.99% of my driving miles are easily in EV Range, or even plugin hybrids. Which is why my next car probably will be the later. However at only driving 350 miles per month, plus the occasional road trip, I estimate my current car will last 10 more years or more.

> I’m wondering, when LLMs become stronger, will we still need vector-based retrieval? Or will we need a retrieval method that’s more like how humans do it?

If we knew how humans do it well enough to reproduce it, we’d probably skip straight to that. Everything in AI, though, is basically throwing ideas at the wall about how you might get closer to that, starting from very little knowledge of the mechanism and lots of anecdotes and subjective impressions about, but very little structured understanding of, even the behavior we want to mimic.

Dude, fuck off. The full quote which you've taken out of context is this: "I'm not complaining here because because I need some platform to say my piece."

I hate it when people twist statements. I literally said I am not doing that. I am just stating the god awful truth which is: Bart is total shit. But here's another truth: When you manipulate my statement and take it out of context it makes you a shit head too.

Great recommendation, although the limited assembly language doesn't give you access to memory or a stack. Zachtronics have a couple more assembly-language-like games - TIS-100 and ExaPunks - both of which are also excellent for exploring the kind of coding you can do in a very limited programming environment. ExaPunks offers the most programming freedom (including a fully emulated handheld video game device you can use to implement actual games); TIS-100 is probably most like real assembly programming.

It is actually the largest car I've ever owned, and if it was up to me it'd be a few inches narrower in the very least. I prefer sub-compacts. As it is I miss my first car, I could squeeze in-between almost any 2 cars and be able to open my door and get out. A bit more clearance in the EUV would be nice, I definitely miss out on some spaces because of the extra width compared to my past cars.

The camera is super useful when parking in narrow spaces in those parking garages where each space is flanked by concrete pillar on both sides (why design it like that? Those pillars are covered in car paint...) or when parallel parking on a one lane road that has cars parked on both sides (always fun!).

There is actually one underground parking garage I have to use occasionally that has a hairpin turn to get out, and the wall is an interesting mish-mash of car paint colors. I've turned on the cameras for that curve as well, absolutely horrible garage and having a top down view really helps out.

I helped cut off the tail cone of a Boeing 747 (former United tail #882) using of those at the Tupelo MS boneyard a few years ago. Well, actually I drew a sharpie line and said “cut here” and someone did.

There’s a pic of the result of our handiwork on Airliners.net, I have much cooler and closer pictures with sparks flying and non-OSHA approved crane rigging being employed that I unfortunately cannot share, but yes, hot knife through butter described it.

As someone who has been fascinated by the universe and galaxies from a young age, I too thought interstellar was the way to go. Nowadays, however, I've started to feel that we've been wrongly conditioned by science fiction to see interstellar exploration as the next logical step for humanity.

Our species is still very immature ethically, socially, and politically. We haven't even learned to accept each other and co-exist happily on Earth. Our distant hominin ancestors crossed entire continents but today we set up physical borders and cultural barriers to prevent even neighborly visits. We certainly won't become the broad-minded united ethical species that Star Trek TOS/TNG portrayed within the next 2-3 centuries.

Gradual spatial expansion, and through that, gradual cognitive and worldview expansion, has been our track record. Whenever things got hairy for someone in our hominin tree at any time, they moved just a little bit more to survive.

So, I feel exploring and settling other solar system bodies should be our next logical step. There are 4 solid planets, 5 dwarf planets, and as per Gemini, ~40 moons, ~3000 asteroid belt objects, and 200000+ Kuiper belt objects, all above 10 km radius. That's a lot of nearby space to explore and more practical than interstellar. Some of them will become the solutions or refuges from our current social and political problems on Earth.

It'll take us 1000s of years more, maybe even 100s of 1000s, to do all this. Including a lot of violence, conflicts and injustice. But eventually, we will learn to develop the cooperative institutions and cognitive/ethical frameworks we currently lack to become a multi-planet species. Interplanetary cooperative institutions and technologies will emerge eventually, just like today we have airplanes, the Internet, UN, WHO, EU - institutions and technologies that, while far from perfect, seemed downright unlikely for 100s of 1000s of years of our hominin history.

A year ago there were some posts about Nova being on shaky ground because Barry was the only one left working on it. This seems to just be continuing the negative narrative. Unfortunate. Seems like he was really close to open sourcing it, which would probably be a boon. It's a longstanding and still pretty popular launcher in the Android world isn't it? I've used it for years on multiple phones.

(OpenRouter COO here) We are starting to test this and verify the deployments. More to come on that front -- but long story short is that we don't have good evidence that providers are doing weird stuff that materially affects model accuracy. If you have data points to the contrary, we would love them.

We are heavily incentivized to prioritize/make transparent high-quality inference and have no incentive to offer quantized/poorly-performing alternatives. We certainly hear plenty of anecdotal reports like this, but when we dig in we generally don't see it.

An exception is when a model is first released -- for example this terrific work by artificial analysis: https://x.com/ArtificialAnlys/status/1955102409044398415

It does take providers time to learn how to run the models in a high quality way; my expectation is that the difference in quality will be (or already is) minimal over time. The large variance in that case was because GPT OSS had only been out for a couple of weeks.

For well-established models, our (admittedly limited) testing has not revealed much variance between providers in terms of quality. There is some but it's not like we see a couple of providers 'cheating' by secretly quantizing and clearly serving less intelligence versions of the model. We're going to get more systematic about it though and perhaps will uncover some surprises.

There are a lots of examples of geo-based pricing that I dont think you'd consider a tariff. Cloud services, Uber, Spotify subscription, etc.

They cost different things based off the country you are in. I guess you could try to distinguish between why they cost different prices in different countries and in some cases it's largely purchasing power parity, but others it absolutely is operational cost differences, such as cloud services. Uber is a bit more mixed - there are definitely purchasing power differences but there are also different regulatory requirements.

All that is to say you could never really tease it all out perfectly in practice.

> This is how you turn dollars into pennies.

It seems important to note, as the article you link does but you do not, that there is no allegation she was trying to steal or damage the cable in use. She was digging for unused cables buried long ago.

That may not be a high-value activity in most contexts, but it is a value-added activity.

It would be helpful to have some examples that show the prompts needed to develop simple shapes, then how to iterate to add improvements. A video of you using it to create something specific would be great.

I first tried "a work table with a roof" which gave me a reasonable model but with a flat roof, then I tried "a work table with a pitched roof" which gave me a very unlikely and unworkable model with the halves of the roof disconnected and not contacting the vertical supports. Then I tried the "Adam Pro" option and it came out looking more like an Adirondack chair than a table, but not one you could sit in! =)

I would like to know what to write instead to get a more useful model. Very cool project though!

> things like smooth scroll help you follow your place in the text

I dislike smooth scroll (and many other UI animations), but there are other things that might help, such as:

- Xaw scroll bars; click to scroll so that the clicked position is now at the top of the screen.

- Line numbers.

- Marker for bottom and top of previous scroll position, if what was previously on the screen is still visible.

"I’ve always felt sunscreen never lives up to its promise."

I agree with that for the same reasons. Nevertheless, I'll still use sunscreen when I have to. In Australia there are times when it's hard to avoid the sun but I avoid it at every opportunity.

If at the end of a day I feel my skin the slightest bit sore from exposure I know I've not been proactive enough.

>Complexity increases cost

Not really. The BOM of a smart thermostat is nearly equal to a dumb one right now. What adds cost is reliability. Hardware reliability costs engineering time and expensive component choices. Software reliability requires engineering resources and a mindset beyond optimizing quarterly returns.

There is no legitimate reason a fancy thermostat should be e-waste after ten years.

This is already a thing in several places.

EU has copyright exemptions for AI training. You don't need to respect opt outs if you are doing research.

South Korea, Japan has some exemptions too I think?

Singapore has very strong copyright exemptions for AI training. You can completely ignore opt-outs legally, even if doing it commercially.

Just search up "TDM laws globally".

ZK rollups which greatly compress data on chain without losing security guarantees, combined with temporary storage using data sampling so each node only has to store a small portion of it. The zk rollups are live and support significantly more than 150tps today, and the data sampling goes live in November. There's a lot more work to be done but that puts the major pieces in place.

Until we have a controlled study, we don't really know if using nouns causes autism either. We don't know what causes autism so everything is suspect.

https://news.ki.se/no-link-between-paracetamol-use-during-pr... concludes that there is no link between acetaminophen and autism based on existing research. https://ehjournal.biomedcentral.com/articles/10.1186/s12940-... concludes the opposite. I'm not qualified to determine which of these studies is more reliable, but the evidence is far from clear if multiple literature studies state the opposite conclusion.

News articles seem to state that the conclusions are clear as day but the same websites were equally sure of the opposite last year.

I'll wait or reliable sources of medical information, which the US government no longer is, to comment on these papers rather than assume whatever paper made the HN frontpage last is the final result of the scientific debate.

> If you stick to 1,6,11 for wifi, Zigbee will co-exist very happily.

I worked for a company that converted a legacy wire protocol with no QoS guarantees to be used over a proprietary modification of Zigbee. One of the managers complained that their volume control would randomly climb to the max loudness. The protocol used press/release packets for button presses and if the volume-up release packet was lost due to interference, you got a runaway increase in volume from the system assuming it was still held down. This usually happened when the channel assignment was in a band used for active wifi.

>No amount of money will compensate for the fact that big corporations rule EU just like they rule any other place on this planet.

That seems hard to quantify. But if it were true, why would the EU let large corporations operate in the EU?

I suppose the answer would be they are only damaging some people but other value them? And EU is catering more to those other stakeholders?

Personally I dont think large corporations have caused such incalculable harm to society but if they have, why even have them?

Tether has been reluctant in many cases to freeze addresses reported to it. At least historically it would not do so if the coins didn’t belong to its direct customers (mostly the large exchanges), rather than individuals who got them from their customers and did crime.

https://archive.ph/6nvkc

The other major issue is it’s easy to get the stablecoins, move them around, cash them out, and by the time Tether freezes them the criminals have already been paid (in dollars, which is what they want really).

As an early Nest employee who worked on the first-gen thermostat I can tell you definitively that you're way off base here. That doesn't mean that Google shouldn't have done more to keep these units alive (and indeed that's one of the reasons I left Google). But these devices were designed in 2010-11. Even keeping the Linux kernel up to date with the latest version is a major undertaking. Adding major functionality like Matter compatibility, or even a simple (but secure!) local API, would take a seasoned engineering team a considerable amount of time.

That said, investing in devices that are local first is certainly good advice, provided the APIs are open and well supported.

I should've been more specific. I was moreso referring to the trend of designers claiming they're adding delight, where in reality they're just muddying the experience with visual effects that might be striking, but lack any depth or improvement to the core experience.

I absolutely do believe that software can be delightful. Linear comes to mind as an example - there are lots of little nuances to their interactions and it just feels so good to use.

> Scientists realized there is no "Truth", only a series of better and better models approximating it.

That’s not accurate. Science is orthogonal to belief in ultimate truth, and scientists have very diverse opinions on that point. Science is about finding more useful models to predict future observations, but whether and how that relates to truth is a question outside of the domain of science.

DNS really is pretty easy. The problem is that Bind zone files are an absolutely godawful interface which makes it seem 10x harder than it actually is. I'm not too upset about it (because it's free software and I figure I can't complain too much), but compare to other DNS solutions and it's night and day how easy they are. For example, running a Windows DNS server (while not something you'd do at home) is dead simple because Microsoft has polished up the user experience. I'm sure some more polished alternatives exist for Linux too, I'm just not familiar enough with what's out there to point to one as an example.

Certainly social- and economic considerations were factors in the southern white migration to the GOP. But it was no coincidence that Ronald Reagan gave a(n in)famous "states' rights" speech in Mississippi in his 1980 presidential campaign [0]. This followed Nixon's southern strategy [1].

Let's get back to the topic at hand [2], namely your assertion that it was Robert Bork's party — the GOP — that supposedly got the 1964 Civil Rights Act through Congress. Yes, liberal northern Republicans such as Sen. Everett Dirksen definitely contributed — as I said.

But you appear to be implicitly memory-holing the (northern) Democrats who drove the process from the White House and the majority in both the House and the Senate: President Lyndon Johnson; Sen. Hubert Humphrey; and Rep. Emanuel Celler. The Senate cloture vote to end the southerners' 60-day (!) filibuster was 27 Republicans and 44 Democrats.

I can't figure out why when I do `t1 left join t2` and it's not 1:1 or 1:0, I get duplicate t1 rows. Why can't either the driver or SQL find a way to represent a single t1 with multiple t2 (this is of course trivial to represent in JSON or any programming language with arrays and dicts).

I don't mind that the tables in relational databases are essentially 2d matrices. I can do the hierarchy with the joins. I just need a way to get the data out in a sane format.

Last time I brought this up ~15 years ago everyone hated on me. But everyone knows this is ultimately the data we want to get out of the system.

> In my imagination, the lab would have some a testing process that spreads a precisely-controlled volume over a standard surface area, textured to be similar to skin, then measures UV transmission percentage vs wavelength with a diffraction grating and photocell. Or something like that!

With this approach, how would you measure the effectiveness of the sunscreen when it's been absorbed by the skin (which is necessary for the sunscreen to work properly - that's why they always say to wait ten minutes after applying before going out into the sun)?

There's a reason in vitro and in vivo are both studied for clinical trials of medications. Sunscreen isn't any different: you're using a product making a specific claim about a clinical outcome, so that needs to be tested.

As others have mentioned, the difference between 75% (SPF 4) and 96% (SPF 30) might seem small, but the latter implies you can stay in the sun 7.5 times as long before getting sunburnt. That's significant. Moreover sunscreen rapidly loses effectiveness, so having "extra" protection might be worth it, especially if you don't reapply every 2 hours or after sweating/swimming, which what most sunscreens recommend.

He doesn't seem to have a lot of stories to tell about his time at Microsoft, but the few he does have were pretty interesting to hear. I think he got used to the dopamine rush of internet praise, ran out of interesting things to say, and kind of pivoted. I would've done the same.

It's not like he needs to peddle merch or anything, I doubt he needs the income. His whole channel seems to just be a hobby and talking about old MS stories attracts Youtuber viewers en masse.

I think there are quite a few more interesting stories he could tell from his more recent time as a malware/scareware developer, but the internet probably won't be quite as appreciative of them as his Task Manager story.
