Jevons Paradox tells us that embracing fracking to reduce coal emissions isn't enough, because any gains in lowering emissions will be offset by people burning more oil. There's a lot of underserved demand for energy, so gradual increases in efficiency (or, in this case, per-watt emissions) do not actually reduce total consumption.

Unless your plan to reduce emissions by embracing fracking comes with laws to restrict consumption - like, the kind of laws you'd have the villain in an Ayn Rand novel pass - then all you will do is increase emissions.

Of course, deliberately enforcing energy poverty is a bad idea and most[0] environmentalists aren't in favor of it. The reason why activists push renewables so hard is because the externalities on those are way better. i.e. pollution will not 'catch up' on solar and wind nearly as quickly, if at all, because solar panels don't emit anything when you're harvesting energy with them.

Also, solar is really, really cheap. It's pretty hard to argue against an energy source that gives you energy too cheap to meter, even if it's only during the day.

DataFusion wasn’t a fit because it doesn’t do external indexes. But why not extend it?
I’m sure he’s great, but that CV sounds much more like Bill Nye (Boeing engineer turned comic turned science communicator) than Carl Sagan, who was an active scientist and researcher his entire career while also doing science communication. Sagan was precocious and started college early, but after that he seems to have had a relatively traditional scientific career path until he became famous.
“Does welfare make people less productive” is not a political question. We can measure welfare and we can measure many aspects of productivity and activity. We can make a quantitative answer to that question. Opinion and ideology is not evidence.

Saying that we need to consider opinions on the same level as actual observations because “political” is fundamentally wrong.

What is political, and must be, is how we act on those findings, the answer to the question “considering those facts, what do we do?” There are many possibilities that are worth discussion, from doing away with welfare entirely to UBI. But this must be based on facts, not ideology. Think tank opinion pieces belong here, in the political discussion.
Sometimes those enterprise tools are used mostly as glorified spreadsheets. I see a lot of BI tools that are really being used to make big spreadsheets.
I like that all major LLM providers are supported: OpenAI, Anthropic, Google, and Amazon Bedrock
So this is a per-room/per appliance battery system? Not sure how this would work for my oil burning boiler, which requires power but has no "plug". Maybe this is better for households that run 100% electric for HVAC?

From what I've seen, most scientists don't even publish their raw data.
“faster typescript” would also be a valid way to say the typescript compiler found a way to automatically write more performant javascript.

Just like if you said faster C++ that could mean the compiler runs faster, or the resulting machine code runs faster.

Just because the compile target is another human readable language doesn’t mean it ceases to be a typescript program.

I didn’t think this particular example was very ambiguous because a general 10x speed up in the resulting JS would be insane, and I have used typescript enough to wish the compiler was faster. Though if we’re being pedantic, which I enjoy doing sometimes, I would say it is ambiguous.
Just use fable and F# instead, your code transpiles to python and rust too
This looks great!

> When an outage happens, the onboard inverter detects the power loss within 20ms and automatically disconnects from the grid (islanding)

How does this work? Do I need to install anything additional in my grid? Like, how does the fridge "know" that it should now draw power from Pila?

Sorry for my noob questions :D
You’re saying vector DBs are the wrong abstraction, but companies keep throwing money at them. Why? Are they just slow to catch on, or are there legit cases where vectors actually make sense?
> but errors are almost always a skill issue

Sure but to compare it to tech, this is why we build tooling like linters and typed languages so that we don’t lose millions of dollars because we needed the average developer to implement a feature. I imagine in heath care it’s even more skewed because a SW eng can see the compiler output and make changes but the person entering the data isn’t (for example) the nurse that’s using the needles to be accounted for
Back in the day, I was proud of how they'd used Amigas to render the B5 graphics as I also was an Amiga user.
Suppose it rains on 50% of days. One forecaster gives a 50% chance of rain every day. Another gives a 90% chance of rain/not rain and is "wrong" 10% of of time. Both stations are giving you accurate information from a probability perspective (when station A says a 50% chance, you know there's a 50% chance of rain tomorrow, when station B says 90%, you know there's a 90% chance of rain tomorrow) but the 50% chance station is less useful as the number is lower. They have effectively given up in the same way pollsters have given up.
Sure but the point is the stock price has little to do with any of that. It’s a meme stock that is regularly pumped with utter bullshit. Just look at what happened today, the King gave it a pump - a full frontal sales pitch TBH - and the stock is up despite all of the actual bad news for the brand.
I don't know why #0 is even one of your examples: the only reason I have to think "trans?" (with the question mark in my thought) is the flag in the background, because without that flag, they look like half of the elderly women I've met over the years.

Yes, a benevolent dictator would want to make financial reporting as difficult as possible as they rob the treasury before the "aviator sunglasses" phase.

I worked in a line of business leadership role for a multi-billion dollar organization. The ledger/financial ops stuff for super high-level reporting and payments were done by old mainframe apps. Everything else was done on a series of Excel spreadsheets hosted on a fileserver somewhere. All sorts of complex stuff was done in there. Finance guys are good at finance and frankly, stuff worked.

They eventually transitioned to a modern at the time Peoplesoft system. The spreadsheet system was better in almost every way to the business units. The ERP was better for the financial ops teams. The shortfalls of the various ERP modules meant that the excel work was pushed down to the lines of business -- we probably had exponentially more spreadsheets, made by idiots who had no idea what they were doing. It also worked, but it was slower and certainly alot more expensive. The tools available for things like budgeting were primitive and ineffective - I literally used a P-Card to buy quickbooks and a built my own little finance shop.
Or possibly you want to use a language you're familiar with in adjacent spaces (eg tools) or you want to tackle concurrency bugs more directly. There is more to rust than it's
Isn't the AOT story for F# pretty meh? AOT + System.Text.Json requires source generation as best I can tell, which F# doesn't support yet (to my knowledge).
Why is it so hard to accept that Harris was _that bad_ of a candidate? Democrat voters didn't want her in the 2020 primaries (not a single delegate won) and she was basically invisible during the entire Biden campaign until the massive pre-election astroturf campaign that tried to revamp her image.
Damn, thanks for plainly stating why we need manufacturing back to the states.
A compromise implies a form of discussion. This post is internally inconsistent.
Cisco makes network equipment (selling shovels in a gold rush), so a high valuation at the time wasn't out of the ordinary, considering Cisco was actually profitable during the dotcom boom, when many newly public companies were 'pre-revenue'. I think of it as similar to Nvidia, who also sells shovels.

> i doubt the Trump admin has strongly vested interest in which post-quantum scheme is selected

That's not the argument being made, you're using that as a strawman to distract from the actual position, which is that indiscriminate layoffs (which is what DOGE is doing) reduce institutional competence and increase the likelihood that whatever scheme is selected is not fit for purpose. Address that argument, not the one you've invented in your head.
> why such single file DB with nice UI are not more popular?

Because it needs skills that often aren't immediately available whereas a lot of people have enough Excel experience to lash up even a moderately complex spreadsheet.
Looks like a very cool product, one I might be interested in buying -- totally depending on price, for which you don't seem to be supplying any clues.
> You can find pretty much anything there, the only thing I struggled with is I like the outdoors and there isn't good hiking (but Chicago actually has really good birdwatching in the city).

Lincoln Park north is not what I would call "good hiking", but I think it's nice for those who like the outdoors. Good for daytime walks, large beaches, dog beach, bird sanctuary, some small natural areas, lakefront trail (paved).

For good hiking, yes you'll have to drive out of the city.
Give me a question and I can give you the output? So you can compare.
They should write a typescript-to-go transpiler (in typescript) , so that they can write their compiler in typescript and use typescript to transpile it to go.
is it not common to write compilers for languages in the language being compiled itself? rust does this i think?

Not quite, there's a long history of legislation about consumer boycotts of Israeli products.

38 out of 50 states have laws on their books prohibiting Israeli product boycott and some form or another.

In the most egregious cases, these do things like fire School teachers if they are choosing to avoid Israeli products in their personal life.

Show HN: I built an app to beat end-of-day Netflix fatigue
Hey folks,

After a long workday, I'd automatically switch on Netflix and let reruns play in the background—almost mindlessly. I spend all day on screens, so the extra screen time before bed felt draining. I love Lenny's Podcast, but it often felt too intense right before sleep.

I've tried reading books as a nighttime ritual, but as a mom of a young kid and a startup founder, it's tough to stay committed to one book over two weeks with so many interruptions and shifting contexts.

So I built Tales.so—a platform that converts books into fun, conversational podcasts. It covers everything from startups, finance, history, sci-fi, to parenting—topics; I've always been curious about but never quite managed to finish in book form.

Why I built it:

* I love exploring new ideas before bed, but I didn't have the energy for dense content or hours of audiobook narration.

* There are many great books I've always wanted to read but never got around to, and this seemed like a way to get a taste of them.

* As a parent, I am clueless about a 100 different things on an everyday basis, and simply listen to top parenting books provides a solid source of information

* I have so much "dead time" in a day—commutes, stroller walks, chores—and this helps me make the most of it.

I am launching it on HN today with 2 key features.

Key features:

1. 20 minute summary by a single host or

2. 60-90 minute by 2 hosts combined with banter and life stories to make it relatable and fun

Using Tales.so in place of endless Netflix reruns has helped me discover new ideas without feeling like "work." It's been great to unwind, learn a bit, and avoid extra screen fatigue at the end of the day.

I'd love any feedback—especially on whether you prefer the solo or duo format, or any book topics you'd like to see. Thanks for reading, and I hope it helps some of you find a screen-free way to relax at night!

P.S. Book I recently listened to —

2. The Whole Brain Child (https://www.tales.so/book/the-whole-brain-child)

Thanks! I've added that to the list.

I'd be grateful of any other such texts.
It was liberalization in addition to strong and relatively benevolent enforcement of the market.

Just allowing the existence of private enterprise doesn't mean much when institutions are weak or corrupt. If you know everyone isn't playing by the rules, the most you can accomplish is rent-seeking while everyone tries to make each other suckers.

If all you have is a strong ML-style government and no liberalization, however, then there's not much of a point in finding opportunities to invest because everything you have is at the mercy of the Party.

China succeeded because investors gambled correctly that liberalization would be accompanied by credible governance, and it can all go away if and when the credibility for investors and entrepreneurs is replaced by Xi's neo-Maoism.

Pila plugs into a normal wall outlet. The fridge plugs into the outlet on the back of Pila. Pila detects an outage in 20ms and automatically begins backing up the appliances that are plugged into it.
Yeah - OK. That one took me about 5 plays to be able to distinguish it.
It is not bogus. It does increase privacy because the extension no longer sees what pages you load or your web content. And it is indeed more performant.

And Apple does care because later on they started to allow blockers to spread blocking rules over multiple sub-extensions. Initially they were limited on... 15 000 rules? Can't quite remember.
Yeah great question. The hardware is capable of bidirectional power, and electrical codes and standards in the U.S. are now catching up with Europe. “Balcony Solar” has taken off there, especially in Germany. Utah just passed H.B. 340 which allows up to 1200W of plug-in solar backfeed. It wasn’t so long ago that grid-tied batteries like Powerwall were working through the same kind of standards updating process to participate on the grid, so I’m encouraged
Some of those defects seem as if they could be used to improve spreadsheet software more than they mean that spreadsheet software is intrinsically inappropriate.
I think piping and method chaining are a little bit different.

Piping generally chains functions, by passing the result of one call into the next (eg result is first argument to the next).

Method chaining, like in Python, can't do this via syntax. Methods live on an object. Pipes work on any function, not just an object's methods (which can only chain to other object methods, not any function whose eg first argument can take that object).

For example, if you access Polars.DataFrame.style it returns a great_tables.GT object. But in a piping world, we wouldn't have had to add a style property that just calls GT() on the data. With a pipe, people would just be able to pipe their DataFrame to GT().

If we adjust to these numbers, we need to quadruple the number of paying users, up to some 1.2% of the total user base. Let's add a safety margin, and bump it to 2%.

Also the USA didn't want to certify European planes, in contrast to the Cold War when they certified the Tornado. That should be the first hint.
Maybe, because it seems like the same old tool still ill-suited for the job. Surely, there are some situations where opaque anonymous money is not the solution, but recognizable reputation is? Perhaps it’s most situations.

Maybe we should use cryptocurrency to decide court cases? Since you haven’t even defined cryptocurrency, I guess it’s up to everyone else to come up with a solution that even makes sense to put your comment in the best light. Sorry.
Crucially, this doesn't just require noise but it requires "taste."

I tend to fall back on music creation as an example of this notion. Lots of innovation in music is experimentation/exploration of "noise," (not necessarily literal white noise) but requires the ear of a discerning musician who ultimately goes "Ooh! I liked that" or passes a "generated sample" by.

This is where I wonder if LLMs can ever innovate. I'm not sure they can develop "taste" for things outside of their distribution. However, I could just as easily be convinced that humans can't either, and sophisticated "taste" is just the exploration of obscure regions of the combinatorial space generated from previously observed samples!

The idea behind OpenAPK - https://www.openapk.net is to follow the app developer releases directly by serving unmodified official binary downloads! All updates are available right on the after the release (no need to wait for F-Droid build). By installing official binary downloads signed with the developer signature you avoid signature mismatch issues caused by F-Droid builds for example.

For most app there is an Obtainium download badge of you want to follow the updates automatically.

I was trying to bit-bang 5 250KHz I2C channels on a 16MHz ATTiny while acting as an I2C slave on a 6th channel.

This is really not something you can do with normal methods, the CPU is just too slow and the assembly is too long. No high level language can do what I want because the compiler is too stupid. My inline assembly is simple and fast enough that I can get the bitrate I need.

In my view, there's two approaches to embedded development: programming á la mode with arduino and any unexamined libraries you find online, or the register hacker path.

There are people who throw down any code that compiles and moves on to the next thing without critical thought. The industry is overflowing with them. Then there are the people who read the datasheet and instruction set. The people painstakingly writing the drivers for I2C widgets instead of shoving magic strings into Wire.Write.

I enjoy micro-optimizing assembly. I find it personally satisfying and rewarding. I thoroughly examine and understand my work because no project is actually a throwaway. Every project I learn something new, and I have a massive library of tricks I can draw from in all kinds of crazy situations.

If you did sit down to thoroughly understand the assembly of your firmware projects, you'd likely be aghast at the quality of code you're blindly shipping.

All that aside for a moment, consider the real cost of letting your CPU run code 10x slower than it should. Your CPU runs 10x longer and consumes a proportional amount of energy. If you're building a battery powered widget, that can matter a lot. If your CPU is more efficient, you can afford a lighter battery or less cooling. You have to consider the system as a whole.

This attitude of "ship anything as quickly as possible" is very bad for the industry.
In complex projects like this, Go requires manual scripting and build-time code generation. Arguably, writing a small shim project in C# is much easier. You don't exactly do a lot of JSON serialization in a compiler either way. Other than that - F# "just works" and does not require anything extra. It is just IL after all.

NativeAOT story itself is also interesting - I noted it in a sibling comment but .NET has much better base binary size and binary size scalability through stronger reachability analysis, metadata compression and pointer-rich binary sections dehydration at a small startup cost (it's still in the same ballpark). The compiler output is also better and so is whole program view driven devirtualization, something Go does not have. In the last 4 years, .NET's performance has improved more than Go's in the last 8. It is really good at text processing at both low and high level (only losing to Rust).

The most important part here is that TypeScript at Microsoft is a "first-party" customer. This means if they need additional compiler accommodations to improve their project experience from .NET, they could just raise it and they will be treated with priority.

This decision is technically and politically unsound at multiple levels at once. For example, they will need good WASM support. .NET's existing WASM support is considered "decent" and even that one is far from stellar, yet considered ahead of the Go one. All they needed was to allocate additional funding for the ongoing already working NativeAOT-LLVM-WASM prototype to very quickly get the full support of the target they needed. But alas.
