> Trying to detect 5ma of current going to the wrong place under a 48-amp load may be impossible

It's actually kinda easy - the way GFCIs work is pretty neat.

You pass the live and neutral through the same magnetic field sensor. So long as none of the current is escaping to earth, you get an equal current in each direction and the total magnetic field is zero.

The problem is you can get a 5mA leak to ground because of, say, condensation inside a socket. And ripping out your house's wiring in search of that is a lot of expense to deal with a relatively minor danger.
Glad to hear someone else doing this. I feel bad not using the grow light to... you know... grow plants. But the light it provides in my office is lovely.
For automating TRV’s, I use Better Thermostat. It allows one to use external temperature sensors to offset the TRV temperature.

Not for business/exec travel it doesn't. Travel agents still exist and are insanely valuable.
I hope they have enough office space ready for this RTO.

Amazon did not and had to delay RTO and even some start dates for new hires.
Same. They asked for proof that I bought it, I sent the PayPal transaction ID and then they went like "lol we don't actually have any records from back then."

I made a hacked version of the old launcher after that and now a couple friends and colleagues and I run a custom server and play on that occasionally.
Oh yes they do! (Granted, it's either because learners input nonsense, or because they fat-fingered when inputting sane numbers... which I suppose are the same thing when you come down to it.)
In my experience, they pretend to, but they try as hard as they can to prevent you from doing it and the timeline is still filled with algorithm guff.
It's closer to Red Hat Enterprise Linux - polished, stable and boring. I can't comment on UI, since I use it only via WSL.
Sure... but for the record, the code that the parent posted is in Python -- one of the global tech economy's pre-eminent programming languages for more than a decade. The parent's example contains some variables with Unicode values that are French words. It strikes me as odd that the parent would say sorry at all. Maybe the parent has a better understanding than I of linguistic sensitivities.

NYC bus drivers start at 27$/hour well above the other costs, and those buses are used ~80-100 hours per week.

Classic school bus costs ~10k/year in depreciation and get 10 miles to the gallon making the driver at an average 18$/hour the largest cost even outside of cities.
Ask HN: What happens to Switch 2 manufacturers after leaks are confirmed?
I wanted to know what happens to leakers and manufacturers that leak actual information, like with Switch 2 which ran rampant and were just confirmed with Nintendo's latest teaser.

Are manufacturers or leakers penalized or persecuted? Is that actually fomented by the hiring company to build hype and serve as free advertising? What happens behind the scenes?
This multi-agent upgrade to Cursor is really intriguing. Splitting the Planner and Executor to better manage the context window seems like a solid approach to tackling those pesky context loss issues. The shared Scratchpad document is a clever way to keep everything in sync without missing important details.

The DuckDuckGo bug fix example you shared really shows the practical benefits of your system. I’m curious about how you ensured the Scratchpad stays updated in real-time—did you run into any challenges with that?

Also, tweaking the prompts to prevent the Planner from over-engineering is a smart move. Do you have any tips on finding that sweet spot between thoroughness and practicality?

One thought I had: have you considered integrating NotebookLM with o1? NotebookLM’s strengths in fact-checking, handling long contexts, and providing well-grounded answers could really complement o1’s planning capabilities. Plus, its ability to manage audio references might add another layer of functionality to your system.

How does your setup handle scaling with more complex projects? And with multiple agents interacting, what security measures are you using to protect shared documents and databases?
I can guarantee you it is a limiting factor.

The majority of bus drivers are semi-retired folk looking for something to keep them active and earn a bit on the side.

I'm speaking from experience.

Pre-internet, there was a fairly common trope of a kid discovering a dirty magazine, often hidden in the home by an older sibling, and showing it to their friends. Nothing actually happening, they were just sharing the images. GP seemed to just be suggesting that updated for the internet age.
Overcoming the Friendship Recession
It's cheaper to get a refurbished rack server than a tower version of the exact same machine (because there are a lot more decommissioned rack machines).

I guess I'll have to try my hand at 3D printing bigger stuff.

Bluesky is ad free (for now).
I don't think you should treat unsafe code as that level of toxic. It's necessary when interfacing with with system APIs. The important part is that you try to have safe wrappers around the unsafe calls and that you document why the way you're using them is safe.
Tried it. Its better for anything than anything from OpenAI. Masayoshi Son is just burning money.
I have light rail literally a 5 minute walk from my house in an inner ring suburb, and I never use it. It was built to go downtown 100 years ago, and I never go downtown for anything. It's completely stuck, has to still cross over streets and follow traffic patterns, and then only runs every half an hour l. Instead I just drive. Yes I hate it too.

So light rail or trolleys is the same but worse and more expensive (plus they also still have drivers).

For this to get used, it needs to:

- not be beholden to traffic or congestion. Like a subway or the L? Or dedicated lanes for busses could work and may be drastically cheaper

- needs to be able to service lots of destinations and changing needs. Subways do this by building new lines and stations (again, $$$)

-needs to be relatively clean and safe. This is an actual concern people have that has to be addressed.
Self-driving cars have actually made progress. Better sensors, better programming, etc. Tesla can't do it but clearly Waymo can. It's not perfect, but with enough time and effort it can get to the point where it'll be regularly usable in most cases.

But LLMs? Those have already scraped all the data they're going to, and bigger models have less and less impact. They're about as good as they're ever going to be.
Even if you want your software to be used by the public, it still doesn't need to be turned into a product, there are other schemes of financing it. You can, for instance, write it off as R&D (which is what programming actually is) or whatever category is assigned to the "donating to Linux Foundation" line in the spending accounts of IBM/Oracle/MS/etc.
Google commits to combatting fake reviews in the UK after 5-year probe
It's really not. I have well over 100 "smart" devices, but a large portion of those will be light bulbs and door/window and motion sensors. I haven't looked, but I'd say they account for 80%+ of the "smart" device count.

Almost every bulb in the house is a smart bulb, every external door (and some internal doors) has a sensor, some windows, and some rooms have motion sensors, in some cases more than one. Every room with at least one smart bulb has a smart switch, whether a wireless dimmer or the actual light switch on the wall.

The bulbs, you group together; I use the "Circadian Lighting" integration rather than "Adaptive Lighting" and it _does_ support light groups, so all of the bulbs in my hall can be managed by a single group entity, the 5 spots in the main bathroom, same thing, 4 in the en suite, same, etc etc.
maybe in some places, but usually the problems with buses are insufficient headways and lack of traffic priority.
LLMs can absolutely translate ideas to code. How is that even a topic of debate. It might not always be good or maintainable code, but the whole notion of "it's just a next token predictor" is so trite at this point.
My guess is that it is likely from Y caps filtering common-mode noise. They are great for filtering EMI to pass strict emissions regs, so it is easy to use them liberally.

I'll admit I don't know what kind of currents they see, but 5mA on transients wouldn't be particularly surprising. There is also the factor of how sensitive the GFCI is.

I agree that it is usually so... until they start making public policy.
I had to check the Rustix implementation again, because that would indicate that that terminal-size wouldn't work on a number of operating systems. However Rustix also uses TIOCGWINSZ in it's tcgetwinsize implementation.
Hmm, I'm apparently correct for C++11, where calling getenv only is thread safe, but that's not guaranteed by earlier standards (or, as far as I can tell, by C or POSIX).
The problem as you imply is that no one does this. Every time I've heard about, witnessed, or experienced silence, it is with a promise of contact that never comes. Browsing various job related sites and even Glassdoor (for what little it is worth), you can see many people with these exact complaints.
A new bus costs about $400-900k (diesels are the cheapest, electric are the most expensive).

I would guess a driver costs $60-90k year including taxes and benefits.

Drivers aren't a majority of the cost of operating a bus, but I'd bet it's at least 20%.
Because point-to-point self-driving taxis are a fool’s errand. They don’t alleviate congestion, they don’t improve traffic flow, they don’t improve urban planning. They’re a direct replacement for individual cars, but now rent-forever as opposed to owning or leasing ourselves. The whole concept is just to remove another strata of ownership and funnel more money to Capital and away from Governments, which I guess is the whole point if you genuinely don’t like governments for some reason.

The healthier option for the masses is expanding mass transit networks, not luxe taxis. Light rail is infinitely more efficient and safer than individual vehicles, be they owner-operated or self-driving. It moves more people, further, faster, and cheaper than any potential self-driving automobile. When you include the whole of networks - ferries, bus routes, commuter rail - they’re the single most effective solution to everything self-driving car proponents claim their products can do, if only they had another round of funding.

I’m not saying we should stop investing in the technology, mind. I just think it’s a better use of our limited resources to invest in improving, expanding, and modernizing mass transit than to build armies of privately-owned taxis, self-driving or otherwise.
"This was before Home Assistant offered their own hardware... Home Assistant uses SQLite, and when you have a ton of sensor data flowing in, SQLite can start choking."

Their $99 hardware works great. Some devices are chatty but it's two lines in the startup config to filter the bulk of it, with no useful functionality lost.

If the data being generated by your living room is overwhelming SQLite on an eMMC, wow.

Home Assistant is one of the few recent products to delight me during setup. The sheer number of weird things it found on my network was impressive. The number of them that are dropping off as various cloud vendors try to lock things down, even more so. It has definitely motivated my future purchase choices and pushed me to simplify.
Maybe this is extrapolating a bit too much from this, but this would be sort of neat as a game streaming compression system right? If the service only needed to send a frame every 1-2 seconds, and the interim could be interpolated locally, still but still processing key strokes, it might be juuuuust smooth enough to not notice. Sort of like DLSS, but game specific, and "upscaling" a frame over time instead of resolution.

That is of course dependant on running inference locally being somehow less intensive than just running the game. But there we go, it's an interesting thought at least!
There are many people who are too young, too old or lack abilities necessary to drive places: they are completely dependent on the will of others to help them get where they need to go. Coordinating the transportation is taxing in many ways and having more options for people to get where they need to go on their own terms is helpful for borders as well as those providing service. Many people cannot leverage existing busses because they don’t go where they need to go when they need to get there. Having something that can more dynamically adjust to meet demand could be very helpful if it can do more than replace the existing system.
I have been using Home Assistant since before "Lovelace" UI was available. It has come a long way but there's still an ongoing maintenance demand. It's less than it used to be... but it's still not zero.

> That said, using it has put me hard on the side of preferring home devices with open management platforms.

I feel like this is the true purpose of HA and the ecosystem around it. Similar to how matter is forcing IPv6 adoption on micro-controllers, really.

Every holiday season, I go looking for a bunch of cheap stuff on Ali express to tear down. Every year there's new LED light controllers and 2024 was the first year where the manufacturers were almost _bragging_ about how they label the GPIO pins and expose the programming interface so you can throw your own firmware on there if you want. Seriously, never before have I seen these controllers BRAG about how they support WLED natively. The FOSS / DIY / I'm not using _your_ cloud, I have one at home, already movement is ... actually being catered to!? That's _new_.

That sounds great but it makes you wonder, how are they going to solve their extremely bad birth rate? Within one generation they will be back to 1950s population levels.

I guess unique challenges will call for unique solutions. Maybe 50% of the population of 2100 will be robots or something and we will be living in Star Wars.
Not sure about the States, but in many other places buses require / strongly prefer a separate public lane. Driving more busses in a congested city will probably increase congestion because buses are "clumsy" compared to smaller city cars.

Adding buses to already congested streets might just make the situation worse.

Israel ran into this problem, and they are desperately trying to recover by building light rail in big cities.

One issue I have with Home Assistant is the dashboard set up. I recently picked up a used crestron power over ethernet touch panel that I have mounted in my wall and I’m thinking I might have to write my own dashboard for my house because the Home Assistant default is not great. The system works best when it’s mostly automated.

In the US. Other markets aren't quite as skewed. Canada has Kobo/Amazon in very similar marketshare for example which is why Canadian Kindle prices are waaaay under what the exchange rate would suggest unlike pretty much every other electronics.

The problem as always is NIMBYism. It's not the desire to improve or the budgets that pose a barrier, rather it's the individuals whose housing arrangements would be negatively affected that raise a fuss. They rob all political will from the movement.
Yes, we are assuming a log that picks linearizability at the cost of availability under partitions. Like most logs do, including Kafka, Pulsar, RedPanda, etc.

The application state is defined by the log here, and the log drives retries/recovery, so it doesn't much matter if the process that executes the app code splits off. The log would hydrate another one.

Also the one log is at the granularity of a single key or handler execution. More of a logical log, than a physical log or even partition.

In Restate, we implement a logical log-per-key, backed by a partitioned physical log.
Handling Traffic Spikes with Vector
Well, in developed countries the wage cost of the busdrivers are >50% all other costs. So you could almost double the number of buses, making it much more attractive to take a bus.
That's what the rest of us are doing in event-sourcing land, but TFA is arguing for something much stronger:

If everything’s in one log, there’s nothing to coordinate

The rest of us have to coordinate the logical log of user creation/deletion and the logical log of user payments, etc.

Separate logical logs with no need for coordination can only work if they are truly independent systems - no causality between them.
And Donald Knuth!

But I don't expect Brandon Sanderson to finish that one. In fact, I don't expect anyone to even think about it.
Kind of a weird take. Don't places that are considered to have great public transport have lots of buses?

Just as driverless trains are a thing, it seems obvious that buses should also mature to be driverless?
Be prepared to be left behind.
I'm not sure what you mean exactly by "countable in a computable sense." Sure, certainly you can't generate one program that enumerates all the programs that compute real numbers.

But the set of programs that compute real numbers is a subset of all programs, and the set of all programs is countable. Therefore the set of computable numbers is countable.

edit: I think maybe it wasn't clear that I'm talking about cardinality and measure? To be a little clearer - I'm saying that the computable numbers have (standard) measure 0 because they have countable cardinality. Any subset of the real numbers with countable cardinality has measure 0. And the set of all real numbers, of course, has uncountable cardinality.
I'm Starting a Search Fund
I think the missed a big opportunity with this kick starter by not offering people anything meaningful when they back it. They easily could've included people's names in a credits in an app as a reward, or made some fun limited edition stickers or phone cases that can be produced for cheap. Right now the kick starter is just basically a donation page.

That all being said, they've raised $57k so far so good for them.

(Edit: spelling)
Yeah that's a fair point! It's def a more general tech thing, but I think there are a couple specific reasons why it comes up more here though. Firstly, I think most tech does not improve at the insane rate that AI has been historically, so people's perception of capabilities become out of date just incredibly rapidly here (think about how long people we're banging on about "AI can't draw hands!" well after better models came out that could). If you think of the line as a way to say "don't anchor on what it can do today!" then it feels more appropriate to go on about this more for a more rapidly-changing field

Secondly, I think there's a tendency in AI for some ppl to look at failures of models and attribute it to some fundamental limitation of the approach, rather than something that future models will solve. So I think the line also gets used as short-hand for "Don't assume this limitation is inherent to the approach". I think in other areas of tech there's less of a tendency to try to write off entire areas because of present-day limitations, hence the line coming up more often

So you're right that the line is kind of universally applicable in tech, I guess I just think the kinds of bad arguments that warrant it as a rejoinder are more common around AI?
Sounds like a lot of work, so you would need to be highly motivated.

> Or dedicated lanes for busses could work and may be drastically cheaper

This is discussed a bit in urban planning circles, one of the reasons trams or light rail is preferred is political, it's much harder for some austerity government to come into power in a city and remove tramlines than remove bus and bike lanes.
