RMSE of current digital clocks rounding down is roughly 34.5 seconds.

RMSE of proposed rounding to closest is 17.5 seconds.

The new method is roughly 17 seconds more accurate on average.

Does this reduced error make a significant difference? Probably not. There are very annoying practical issues with this proposal though.

Rounding down makes it clear what minute has already passed. If your clock says 3:00, you know the current time is definitely some point after 3:00. If something needs to happen at 3:00, and your clock says 3:00, it is time to start.

With this proposed method, 3:00 could mean anywhere from 2:29:30 to 3:00:30. When do you start? Do you start as soon as your clock says 3:00? Then you're starting 30 seconds early. Do you wait until your clock says 3:01? Then you're starting 30 seconds late.

And how do you set a clock that uses this scheme? If I want to set the clock to 3:00, do I wait until 2:59:30 and then set the clock to 3:00?

The headaches that arise from this scheme are not worth the trivial error reduction.

Please, disagreeing on a topic and providing arguments is one thing, but suggesting somebody go live in another country because you don’t agree with them on something that happened in their country is disrespectful.
Also vaguely related, I've come to realize some people find metric measurements easier than feet and inches.

I find the fractions simpler. Need a half of that half? Just double the denominator.

My wife would seemingly rather keep counting .1 centimeters.

The same applies with clocks. It's easier for me to rough out how long I have if I just chop the face into fractions vs mental arithmetic, as brutal as that sounds. What do you mean this guy can't divide 30 in half?
Same, although I don't miss the old gaslighting of lost flipper hits on poorly maintained tables (such as when pressing the flipper button doesn't sufficiently make enough contact to trigger the flipper). It kills me that they're so expensive still.
I really wish htmx would use fetch rather than xhr, and now it looks like that won’t happen. Fetch is easier to proxy, so it would open up a lot more possibilities for backends, like ones running in browser or a native process. I had to hack together a xhr fetch proxy to make this happen.

You can definitely use your IP to take down scams.

As far as I’m concerned you are a black box. Just as I’m a black box from your perspective. In principle I could come over and vivisect your brain if you’d like, but I doubt you’d be interested, and I wouldn’t really want to incur the legal liability even if you were.

Besides, “black box” just means that your internal mental life and cognitive mechanism is opaque to me. It’s not like I’m calling you a p-zombie.
lol this incredible hyperbole begs for explanation.

The two main fumbles I can see of note are on housing and immigration.

On immigration the government only made remarkable changes in the last two years, and as if they touched a hot stove, they already realized their mistake and have already scaled back immigration numbers so much that Canada will effectively have nil immigration for the near future. Not likely a generational issue here.

On housing well I agree it'll take a generation to fix it but that was already the case before the Liberals took power. Very much an example of the future is already here but not yet distributed as Toronto and Vancouver were already experiencing a housing crisis in 2014.

Less an issue of what the libs actively did wrong but more an issue of how slow they were to act on the fact that Canada has had bad housing policy since the 1990s and few jurisdictions are taking things seriously. Fed housing policy at this instant is actually pretty good in that it is mirroring and supporting the good BC NDP housing policy. It'll take a long while though for homes to get built and likely things will get worse as the Conservatives scale back on investment.

Glyphosate exposure, either through active ingredient alone or commercial herbicide formulations, has the potential to induce dysbiosis by creating an imbalance between commensal members of the gastrointestinal microbiome and opportunistic pathogens. Glyphosate may be a critical environmental trigger in the etiology of several disease states associated with dysbiosis, including celiac disease, inflammatory bowel disease and irritable bowel syndrome. Glyphosate exposure may also have consequences for mental health, including anxiety and depression, through alterations in the gut microbiome. However, the research surrounding glyphosate’s effects on the gut microbiome also suffers from numerous methodological weaknesses including artificially high-doses, insufficient duration, proprietary ingredients and an over reliance on animal models. Future long-term studies examining physiologically relevant doses in both healthy and genetically susceptible populations are warranted to determine the real risk posed to human health.

But the difference might not be between Harvard and a local community college. People don't come out of "slums" to Harvard and immediately join the upper class.

But you'll be exposed to different people and opportunities by going to a state school instead of a community college, or a better school out of state with a scholarship vs. a state college, etc. The small differences matter.

I literally got my first job because my roommate's dad knew of someone looking for a software developer job. Would I have met that person in community college? Maybe! Lots of people with good networks go to community colleges, too - but I'd bet fewer than more expensive schools.

I agree that, generally, accusations of fascism come down to a disagreement over some lower-level belief about what is a "harm" and what harms should be tolerated.

My issue with the article is its analogy to sentient tic-tacs.

The vast majority of disagreements are about human beings, who counts as a human being, and to what extent that human being should be allowed to live as they want.

You've landed on a juicy strip of fly-paper. You assume there should be a world view, a coherent theory or... well, something.

There's not. Musk is a hollow shell of a person. He has no principles, no ethics, no shame, no honor. He has one goal, and that is aggrandization of his ego. Getting rich—by stealing, appropriating, scheming, evading taxes, procuring public funding, withholding payments to the people that work or worked for him—whatever it takes, he'll just take it. He will not say thank you, and if you're among the ones holding his ladder, be prepared for a kick with the boot right where your teeth are.

He will not cry over your dead body, and he has repeatedly shown that he doesn't care for other people, animals, wildlife—it's all up for grabs, creation is a fun house full of moving and not moving critters waiting to get exploited by him. He laughed over the cruel seal experiment they did at SpaceX (interview with Tucker Carlson). He ditches all and any regulations. He's not to be held accountable. He's beyond the rules.

OK I'll stop here for the time being. Fascism is not a political direction. Fascism is crime against humanity. Elon Musk is a criminal already, now he has turned into fascist, we can be pretty sure his more heinous crimes are still lying in the future.

When I was in elementary school, my teachers told me it was very important to memorize multiplication tables because I wouldn't always have a calculator in my pocket. We know how that turned out.

I asked an LLM the first example question (convert 3 minutes to seconds), and it provided not just the answer, but that there are 60 seconds per minutes, so that's 3 * 60 = 180. I don't think an 11 year old is harmed by that sort of assistance.

If nobody believes it, then is it actually true?
Manufacturing is all about management though, isn't it? Management is the make or break in that industry. Sure you can coast with your current setup, but that isn't enough for an auto company long term.

You need to manage your PLM (product life cycle CAD/design software) integrated to your EBOM (engineering bill of materials) to your MBOM (manufacturing bill of materials) to support your ERP (enterprise resource planning) in support of your MRP (manufacturing resource planning). All of that requires people at higher levels that understand the systems at the conceptual level and the company specific level, working together to make sure that 40,000 parts manufactured in house and purchased externally, all with varying lead times, come together at the exact right time to build the correct model/configuration for the market right now.

I've seen plenty of companies making bank today but that were doomed because they no longer did any of the above, they fired management, they outsourced design, they outsourced IT, they coasted on prior managers work in setting/configuring everything and it all became fixed in place as is. Best they could hope for was to bring in consultants to heavy lift changes as part of 'major' efforts going forward, allowing what managers would have been continually adapting to pill up until it became such a big issue money was freed up for the consultants.

Nothing will happen. Nobody cares about relatively small groups of geeks. People will write angry posts at Youtube, but there's nothing anybody can do.

For example, RZX Archive channel (that hosted replays of ZX Spectrum games) was taken down by fake copyright strikes. Its author died several years ago, so nobody could fix that.

People have felt the same way about waning handwriting skills and reliance on calculators.

The truth is the way humans process information has been radically altered by LLMs and we're in the absolute infancy of understanding what that means. It is going to be far more disruptive than the keyboard or calculator. As we discover the implications, we are repeatedly going to find ourselves disturbed and disoriented. There are skeptics who think it's all hype and that current approaches are a dead end. Even if that were true, I'm 100% convinced that even if AI didn't meaningfully improve on today's capabilities, it will still be incredibly disruptive.

Buckle up.

There will be 2 categories of winners of the AI revolution: the quick and the deep.

This poster's little sister is "the quick". She is using AI intuitively and aggressively. Whether it's right or wrong isn't important, because if the payoffs of it being right are more than the costs of it being wrong, she will be vastly more productive than people who are not using AI. A lot of the thinking school has traditionally trained us to do is officially commoditized.

"The deep" are people with strong conceptual understanding of the problems to which they are applying AI and/or strong understanding of the AI itself. They will use AI to create things that didn't exist before. They will take seriously the risk management (although, they will still not be able to successfully predict all unintended consequences).

People will benefit in the new world proportional to their ability to create or extract value.
That logic seems like it would outlaw labor strikes too, especially in important industries. Sometimes, holding the economy hostage is the point.

I take exception to the framing of “attempts to settle this.” The government used violence and threat of violence to make the problem go away. There wasn’t an attempt at compromise. Do what I say or else isn’t an attempt to settle.
The Chinese Room was a lame thought experiment. It requires a book so wondrous that any question looked up has an answer convincingly human (it's just that both the question and reply are in a language the person shuffling pages doesn't understand). The Book can be seen by a modern audience as equivalent to the distillation of all that LLM training.

It's odd to me to present an argument on human vs. machine intelligence and completely skip over what human intelligence is — exactly what it is about human intelligence that is so distant from this "trained" (educated?) book.

(I think I am also speaking for Karl Pilkington when I say that I have no way to know that the little man in my head that is busy flipping through the Calhoun Book has a clue as to what I am on about either.)
Humor , in general, relies on the presenter holding an accurate theory of mind of the audience, then subverting expectations in a way that mocks convention, is ironic,
Or speaks a widely known but little acknowledged truth.

LLMs don’t have anything significant in terms of theory of mind, although that could probably be trained in with significant effect to the conversational capabilities of LLMs.

> The largely conservative provinces have done a very good job of blaming Trudeau and immigration for problems that are entirely their own.

No. Immigration reduces available housing. Immigration overloads the health care system. Immigration strains the education system. Immigration creates ethnic enclaves that are hard to police.

Immigration is a federal responsibility. Trudeau and the Liberals are to blame.
Show HN: I built an offline open-source RAG system DataBridge
Hey HN!

Over the past few weeks, I’ve been working on DataBridge, an open-source solution for data ingestion and querying across text, PDFs, images, and videos.

In our latest update, we’ve added a fully local deployment option:

- No internet required – Runs entirely offline.
- Customizable Models – Supports any LLM and embedding model via Ollama (with options for any other private providers)
- Extensibility – You can plug in your own models or tools easily.

This local-first approach ensures better privacy, security, and flexibility, especially for teams dealing with sensitive data.

You can check it out here:

Docs: https://databridge.gitbook.io/databridge-docs
Code: https://github.com/databridge-org/databridge-core

If you can try it out, would really really appreciate it :)). Any and every feedback welcome.

What’s dreadful is the rising cost of living and lack of affordable housing, which he failed to address. Moreover he doubled immigration during a time when the average Canadian was struggling to keep up with rising expenses.

I’m pro-immigration but not at an unsustainable rate. Housing construction was not keeping up.

Trudeau pushed beyond the limits of pro-immigration policy. If it was just conservative propaganda, the liberals wouldn’t be looking at a potentially historic election loss based on current polling.

That said, I don’t think conservatives will fix anything.
My take from it was that the question prompted the change author to introspect his feelings about the change and revisit it, making it better.
The Chinese Room metaphor is also about consciousness, about thought in general.
It's not a question of 'stay inside for weeks' or 'go out' though is it? It's a spectrum and there are a lot of basic precautions like masking possible that people refuse to do.

Personally I live my life but will continue wearing a KN95 until Covid stops being in active circulation. You can call this paranoia but I haven't caught anything since I started doing this and taking other basic precautions like distancing - no covid, no flu, no colds. So I'm benefiting from it and by doing this I'm less likely to spread a disease to someone immunocompromised.

Earlier during covid I saw a lot of people doing the same, which I appreciated. Now I'm the only person doing this and it makes me a little sad, because if I spread a cold or flu or covid to somebody's grandma, they might die even if the virus is no problem for my younger immune system.

In other countries it's conventional to wear a mask any time you're remotely sick or have symptoms that might indicate illness, but we don't do it here. Instead, people go to work while sick and make their coworkers sick.
