Finally, a life-sized RC car. In my opinion, fast swappable batteries were always the best way to do an electric car. Comes with its own set of problems, but the approach would make electric cars cheaper... possibly no charging circuits, batteries not included (lol) and the car itself would last longer, with battery degradation no longer being tied to the vehicle. Vehicle might maintain its value over a longer time since there is no battery to degrade. Range and performance could improve with battery technology.

Negatives would include inconsistent KWh/performance between packs; Could you own a pack and charge at home or would you be restricted to renting one? Who is liable when it catches fire or you get in an accident and wreck a pack? A pack swap would probably cost more than just charging. Do you 'buy-in' to a pack separately or is it baked into the cost of the vehicle?

Then you have to get all the auto manufacturers to agree on a pack specification.

Sounds familiar. I did fine in my career, but it never felt like enough and I missed a couple of major opportunities, so I'm not even sure how smart I was. Just high IQ, high test scores, yadda, yadda, yadda. Just wanted to really "kill it" just once, but so far no and now I'm 52.

It's good to see more competition, and open source, but I'd be much more excited to see what level of coding and reasoning performance can be wrung out of a much smaller LLM + agent as opposed to a trillion parameter one. The ideal case would be something that can be run locally, or at least on a modest/inexpensive cluster.

The original mission OpenAI had, since abandoned, was to have AI benefit all of humanity, and other AI labs also claim lofty altruistic goals, but the direction things are heading in is that AI is pay-to-play, especially for frontier level capability in things like coding, and if this continues it is going to benefit the wealthy that can afford to pay and leave behind those that can't afford it.

> So, it's oddly perfect for introverts in that sense. Nobody goes there to talk.

For an introvert, the only place better than being in the crowd at a music venue is being on the stage. There are sooo many introverts in bands and especially DJs; some of the greatest musicians are introverts. Performing is a form of radical self-care, and introverts are actually really good at judging the vibe of a crowd.

The tricksy and most-insidious thing is that American consumers paid more money to the companies that raised prices on account of the tariffs, yet if the tariffs are invalidated, the companies will get the refunds and will pocket the money.

So Trump and the Trump-adjacent win either way: if tariffs stand, then they will have successfully funneled additional power to the Executive Branch and acted out the GOP's international policy goals; and if tariffs fall, then effectively corporations will claim American consumers' tax refunds.

I used to use substack as a weak signal for quality, but still a signal. As of late, I've seen a bunch of substack articles by different authors posted here that don't pass the weakest of scrutiny. I don't know how you even make an error as simple as this.

The press release he linked to couldn't be more clear as to what the $404m number was in regards to. https://www.businesswire.com/news/home/20251103432446/en/Hip...

Another quote from the article:

> What’s worse, more than 80% of AI-guided calls, Hippocratic’s main product, come from a single client—likely another one of Munjal’s or Hemant’s buddies. The company’s burn rate now stands at $404M.

"likely another one of Munjal’s or Hemant’s buddies"? wtf, is it, or is it not? what kind of analysis is this?

The FYRTUR blinds were kinda crap, constantly had issues with them losing their minds and having to redo the setup. I also have the later Tredansen cellular shades, and those have been good ... but I just checked and those seem to be discontinued as well.

Perils of being early adopter, but kind of soured on the whole smart home concept unless you are wealthy enough to redo all of your home lighting and window treatments every 10 years. Apart from the effort, it creates yet more e-waste. I have 30+ year old manual window shades and lamps and they all still work.

Hi all,

We have been playing with repeatable and re-usable flows that someone can run on either Codex, Claude, Cursor or other AI agent. Today we are releasing an open source protocol and a set of tools allowing anyone to declare AI-driven flows (a.k.a. Recipe) and execute them.

In a nutshell, it allows to describe some AI-flow that can be executed by any AI coding agent (Claude, Codex, Cursor). The flow may contain of multiple context files, commands, permissions configuration, etc. The tool generates a setup native to the AI agent, so it works as a provisioning system, not a wrapper, MCP or some sort of other external dependency once provisioned.

Woul love to hear your feedback!

"Are there any good resources on optimizing python performance while keeping idiomatic?"

It is essentially impossible, "essentially" here using not the modern sense of "mostly", but "essential" as in baked into the essence of the language. It has been the advice in the Python community pretty much since the beginning that the solution is to go to another language in that case. There are a number of solutions to the problem, ranging from trying PyPy, implementing an API in another language, Cython/Pyrex, up to traditional embedding of a C/C++ program into a Python module.

However this is one of those cases where there are a lot of solutions precisely because none of them are quite perfect and all have some sort of serious downside. Depending on what you are doing, you may find one whose downside you don't care about. But there's no simple, bullet-proof cookbook answer for "what do I do when Python is too slow even after basic optimization".

Python is fundamentally slow. Too many people still hear that as an attack on the language, rather than an engineering fact that needs to be kept in mind. Speed isn't everything, and as such, Python is suitable for a wide variety of tasks even so. But it is, still, fundamentally slow, and those who read that as an attack rather than an engineering assessment are more likely to find themselves in quite a pickle (pun somewhat intended) one day when they have a mass of Python code that isn't fast enough and no easy solutions for the problem than those who understand the engineering considerations in choosing Python.

We’ve all used project management tools. They’re great at listing tasks, assigning owners, and showing deadlines.

But when something slips, a design is late, a review is pending, or a dependency breaks, suddenly everything goes off track.

And that’s where most tools stop helping.

They’ll show you what’s delayed, but not why. They’ll tell you something’s “blocked,” but not what caused the block. They can’t explain how one delay silently ripples across your entire project timeline.

That’s exactly why we built Klarity, a project management tool focused on dependencies and delay analysis.

"Porn manager" - be a manager of porn studio, hire models, choose genres etc. The game becomes hard after the studio becomes big enough because of too many needs to be remembered. Sorry but the game is j2me only, requires something like Nokia S40 or Siemens *75. I don't even trying to find it, I have no compatible devices any more.

Niche distribution has nothing to do with quality of distribution. The user base are passive users versus active users like daily office and game users.

The quality has gone done hill. Windows Embedded / IoT is often used to run your ATMs or some form of industrial automation. Windows actually has a real-time OS (RTOS) mode for just this.

The company I work has planned to replace Windows with Linux for future products and even moving active products to support both Windows and Linux during the transition. Only products that will stay on Windows will be legacy that are near EOL.

Personally, I would never use Windows OS for future products and solutions in these environments. Nor would I use it for network / server based solutions.

>Btw, SF night clubs actively refuse to let “tech nerds” in.

I got escorted past the line at DNA lounge because I had a Firefox shirt on. (Only solid black shirt I had, outta respect to the goths rocked it with some black jeans.)

Are you aware that one of the best clubs in the bay is owned by a former "tech bro"?

>DNA Lounge is an all-ages nightclub, restaurant and cafe in the SoMa district of San Francisco owned by Jamie Zawinski, a former Netscape programmer and open-source software hacker.[3] The club features DJ dancing, live music, burlesque performances, and occasionally conferences, private parties, and film premieres.

https://en.wikipedia.org/wiki/DNA_Lounge#History

In general, clubs don't want to let in folks who don't match the culture... for example, Berghain, at it's core, wants people coming in who want to dance, so if you show up in glasses and Patagonia you're not going to enjoy yourself.

Finally, be mindful of the energy you put out -- any group of people in business casual trying to get into the hottest nightclub in town might find their hopes dashed.

Frankly, based on your post I think maybe an air of entitlement and persecution might be your issue, not glasses or a sweater vest, because spoiler alert: if you don't mention your work, no one knows what you do for a living, and SF is probably wayyyy more welcoming to "uncool" people getting into clubs than someplace like NYC or LA, where if you're not a literal model or some kind of entertainment bigshot no clothing choice (or lack thereof) is getting you in.

Almost all real-world Thread networks I'm aware of have a border router in the form of an Apple TV, Nest Hub, Amazon Echo, etc, so I'm not particularly reassured by the fact that the protocol doesn't technically require one.

I was under the impression IPv6 doesn't need NAT. But you're saying they only get unique local addresses, so even with a border router bridging the connection back to my local Wi-Fi network they still can't send packets out to the internet? "They would have to ask DHCP for a real IP first" doesn't seem like much of a barrier.

I'm in Beijing right now. I was also here 20+years ago. The difference is astonishing. Back then the air was filthy, it was hard to breathe, you never saw the sun. Today it is blue sky most days, EVs everywhere, electric scooters, busses, even garbage trucks. The roads are quiet. The air is clean. The high speed rail system is astonishingly good. This really feels in some ways like living in the future. The West is years behind.

Of course there are still a lot of obvious problems to be addressed, but the rate of progress is the really impressive thing.

The real price of solar electricity is never negative. Unlike something like oil wells (which really have driven the price of oil negative) you can just turn solar off.

Prices have gone negative because of things like subsidies - which in the short term is a good thing IMHO - it subsidizes industries developing systems to make use of that free (but not negative cost) energy...

Yes, I did consider writing "4 colors", but thought someone would say "but you could have 16 colors on-screen" citing the early 80s titles which did scanline palette tricks. So, I went with "16 colors" as it was technically the upper-bound of 'official' documented colors (excluding composite artifact, dithering and other cool tricks). I didn't really want to get into explaining more since my goal was just linking the "8088 MPH" demo for the GP and anyone who hadn't seen it. Also, I have no idea if a technically correct, definitive and complete statement about CGA's maximum possible colors in a single English-language sentence is even possible.

But after wasting... oh, nearly ~800ms on this internal debate, I realized I'd already cleverly chosen to not link directly to the 8088 MPH video but instead a site containing both the video and links to explications revealing the myriad brilliant tricks and unnatural acts behind 8088 MPH. And from that rabbit hole, one may learn more than any mortal should know about CGA graphics. Especially apropos since the author of the OP was instrumental in creating 8088 MPH (although the OP's post is about BIOS things).

There's no contradiction in wanting an abolition (or at least substantial curtailment) of copyright while also being upset that mass violations of copyright magically become legal if you've got enough money.

Enforcement being unjustly balanced in favor of the rich & powerful is a separate issue from whether there should be enforcement in the first place—"if we must do this, it should at least be fair, and if it's not going to be fair, it at least shouldn't be unfair in favor of the already-powerful" is a totally valid position to hold, while also believing, "however, ideally, we should just not do this in the first place".

I mean, if you don't watch the evening news or look for any evidence then I guess you wouldn't think there was public evidence.

CBS Evening News has showed footage of the boats [1]. While this isn't ironclad proof (would you expect the drug runners to hold up identification showing them as criminals?), it is unlikely that these four-engined speed boats loaded with something is anything other than drugs. They are not boats full of people/refugees. They aren't cargo ships operated by a shipping company with any official records claiming to have been lost, or any legitimate tour company. The characteristics of these boats match many other drug trafficking boats that the US Coast Guard has intercepted in the past full of drugs.

You can debate whether the US President has authority to order strikes like this but insinuating these might just be innocent people and not drug runners isn't going to go very far.

> By flooding bug bounty programs with AI-generated reports, they feel productive and entrepreneurial. Some genuinely believe the AI has found something real. Others know it's questionable but figure they'll let the maintainers sort it out.

I’m not saying that AI hasn’t already given us useful things, but this is a symptom of one very negative change that’s drowned a lot of the positive out for many people: the competence gap used to be an automatic barrier for many things. For example, to get hired as a freelance developer, you had to have at least cargo-culted something together once or twice, and even if you were way overconfident in your capability, you probably knew you weren’t the real thing. However, the AI tools industry essentially markets free competence, and out of context for any given topic, that little disclaimer is meaningless. It’s essentially given people climbing the Dunning-Krueger Mt. Stupid the agency to produce garbage at a damaging volume that’s too plausible looking for them (or laypeople, for that matter) to realize it’s garbage. I also think somewhat nihilist people prone to get-rich-quick schemes (e.g. drop-shipping, NFTs) play these workflows like lottery tickets while remaining deliberately ignorant of their dubious value.

I'm just going to copy my comment on a previous post about this topic:

You think that Trump won't demand something in return for this?

I keep telling everyone I know that AI will be enshitified just like every other internet business. Tell me why the incentives will be different this time around. Putting yourself in hock to an aspiring authoritarian is certainly one way to supercharge that process.

What do you think OpenAI's output about Jan 6 will be one year from now if this goes through?

Depending on the nature of your code, just throwing pypy at it instead of cpython can be a huge win. This very much depends on what you're doing though. For example, I have a graphics editor I wrote that is unbearably slow with cpython; with pypy and no other changes it's usable.

If what you're trying to do involves tasks that can be done in parallel, the multithreading (if I/O bound) or multiprocessing (if compute bound) libraries can be very useful.

If what you're doing isn't conducive to either, you probably need to rewrite at least the critical parts in something else.

It is pretty sad that this is happening and that it apparently is at risk of just disappearing soon. I understand there are a lot of ethical concerns with that site, but if I use like the Internet Archive's Wayback Machine to try to save some specific documentation pages for certain proprietary software, it absolutely fails to actually save the content. So then it is just a bit more difficult to save a particular knowledge base article before it might get rewritten or updated.

The loss is not that much - approximately 3.5% per 1000km. IIRC the Changji-Guquan HVDC line reported around 8% over 3300km thanks to working at 1100kV.

Extend that to 10k km and you're looking at approximately 25%, but if it's surplus solar, who cares?

Such a line costs as much as a highway broadly speaking, so it's not impossible to build.

I'm also introverted and haven't been to clubs in over 10 years, so can't speak for today's crowd. Despite being an introvert, I pushed myself to socialize. Primary motivation was just being somewhere fun with friends or work colleagues where I can dance/listen to music I like, people watch, or the one thing most people don't readily admit to: meet potential partners for sex. What actually happened was a lot more of the first thing and A LOT less of the last thing though lol. You're around a bunch of drunk people, something funny is bound to happen and those hilarious moments really made it memorable.

The China "AI" threat? Xi has warned of a bubble, has shut down the Internet during exam time and is in no hurry at all to push this nonsense.

Perhaps the government should loan OpenAI $1 billion so it can donate to a four times larger ballroom, upon which it will receive $100 billion in public money to fund the TikTok Sora videos.

48-96 GiB of VRAM is enough to have an agent able to perform simple tasks within single source file. That's the sad truth. If you need more your only options are the cloud or somehow getting access to 512+ GiB
Show HN: I spent more time writing tweets than building. So I fixed it
by thanhdongnguyen | 2025-11-06 17:32:36+00:00
Hi HN! I'm Don, a developer who realized I was spending more time crafting tweets about my projects than actually working on them.

Last month, I tracked my time. I spent 6 hours building a new React component. Then spent 1 hours trying to tweet about it. Not a thread. Just one tweet. I wrote 12 drafts. Deleted all of them. Eventually posted nothing.

This isn't writer's block. It's decision paralysis. Every tweet requires dozens of micro-decisions: Tone? Format? Audience? Length? Thread or single? Question or statement? Should I be casual or professional? Technical or accessible?

When I talked to other developers, they had the same problem. One friend told me he has 20 draft tweets sitting in his notes app. He builds cool stuff but rarely shares it because "tweeting is exhausting."

I built a browser extension that handles those micro-decisions. You give it your idea. It generates multiple versions in different formats (question, thread, how-to, etc.) and tones. You pick one, maybe edit it, and post.

The key insight: you don't need AI to write tweets. You need it to remove the friction of formatting and structuring your existing ideas.

If you want try it:

Pretty sure the US has always been on the losing side of that, when calculated per capita.

China's numbers did rise quickly on that measure and is above the EU now I think but still way below the US.

And if you don't like per capita, then China with 4x as many people is still behind the US when you compare cumulative CO2.

I had a 2021 Accord Hybrid, and it is not like what you describe. I think it has a different design than older Honda hybrids. It has two electric motor-generators. Below about 40 mph, propulsion is entirely electric. There is a single speed "transmission" and clutch that engages at higher speeds, where the gas motor provides direct drive.

A coronal mass ejection (CME) is anticipated to impact Earth as early as Thursday evening, 6 November EST. Therefore we have a G3 (Strong) Watch in effect on the 6 and 7 November UTC-days. There is a fair measure of confidence in a Earth-directed aspect to this CME and a moderate level of confidence in timing of the CME arrival - which we anticipate with a range from as early as Thursday evening to Friday morning EST.

Who else can and will stop the infernal machine other than the people? Can't see anyone. I hope you're wrong and expecting people to cope is not nonsense, because expecting the FDA or UN or Trump or Xi to do it is even more nonsense.

Anecdotal evidence here. My use-case needs some UI, but a full blown GUI is way, way overkill.

I am building tooling around "Verifiable Credentials" (the W3C standard, OpenID standard, and all the standards around and below it).

So me and my co-workers need tools to check JWTs, resolve DIDs, generate Proof of Possession, .well-known contents and services discovery, do OpenId Connect flows, interpret "offer requests", "presentation requests", QR-codes, etc. It started as a bucket of random commandline things that random devs whipped up when needed (in typescript, python, bash, rust, some PHP), and now slowly consolidated into a consistent "toolkit". I am currently still porting most of these tools to Rust and make their CLI interface and IO consistent.

But from there I'll be adding a TUI very quickly.

By no means meant as "end-user" software - those exist and called "wallets". But for developers and devops working in this niche. These don't need a GUI. I'd even wager these users don't want a GUI but prefer a TUI, but in any case, the TUI is just so much easier and more accessible for me as a dev that it's the choice between a TUI+CLI or no UI, just CLI.
by FarmerPotato | 2025-11-06 17:34:35+00:00
I recall that IBM had a lot of manuals on how to design TUI , known as CUI then. Especially around the advent of OS/2 and PM, as it seemed every DOS app was gaining imitation menus and windows.

A hallmark was that functionality must fit CUI and GUI front ends alike. Keyboard shortcuts would be identical.

I first read about the unified CUI principles in Dr Dobbs' Journal.

It seems a lot of that knowledge is lost or never made in it on the web.
