Don't you work for Pila? Shouldn't you know that?

If you backfeed during an outage, and then the grid reconnects, you're fighting the grid. If you backfeed during an outage and an electrician is trying to fix lines near you, you can hurt them.

Why does the OP say it "disconnects in 20 ms of detecting an outage"? If it's a UPS, it doesn't need to disconnect - It's just no longer fed by the grid. If it's back-feeding, the point would be to _start_ the connection when you detect an outage. But backfeeding is an extremely bad idea.
So, a UPS, or a Jackery
> It is easier to measure in cities, and thus introduce bias based on whatever pavement is populate.

That's a myth.

* MODIS sat readings are available under the precessing polar orbit path and are indifferent to urbanisation or not.

* National BoM networks have always included stations outside of cities and great care is taken to position stations and to normalise readings.

* Urban Heat Island Bias is a myth of long standing; asked and answered three decades ago, two decades ago, a decade ago.

Why is it _still_ being raised in 2025?

To be fair, without the baggage of tesla's ...overzealous... marketing, I think it will be possible for the dealers to pitch for it and yet deliver the message that it's "alpha" and risky.
FWIW, I'm plenty familiar with functional programming and iterator chains, and I still think for loops often beat them--not only from a "visual noise" perspective, but because complex iterator chains are harder to read than equivalent for loops (particularly when you have to deal with errors-as-values and short circuiting or other patterns) and for simple tasks iterator chains might be marginally simpler but the absolute complexity of the task is so low that a for loop is fine.

> But you should be familiar enough that you stop randomly badmouthing map and filter like you have some sort of anti-functional-programming Tourette's syndrome.

I've been moderated for saying much tamer, FYI.

There’s a sadistic element here with the footage. It’s torturing an animal at the very end. There should be a clear rules of surrender here.

Indiscriminate bombing is a major sin. We have no way of litigating the current war criminals, but ICC has warrants out on some. There’s a sadistic element to cutting off food and water.
That kinda-justifies sci-fi depictions of planets (sometimes future-Earth) where skies are darkened by smoke stacks and also shot through with lightning.
I give them Metabase. Metabase pointed to read-replica-3; and via Metabase API one can add lots of meta-data about tables and fields so the BI folk can point & click to build reports (and keep up with schema changes (which I mostly resolve with views anyway))
why bluey or cocomelon? mister rogers is chronically untalked about for kids content in 2025.

its an incredible show and deeply enriching for both me and my little one. we’ve given our two year old very limited screen time with mister rogers and, since, they’ve taken up great fondness to making believe, we talk about characters and situations on the show regularly, and they naturally separate themselves from the screen after a while.

I’ve been very strict about exposure and screen time but mister rogers has been a blessing and provided me great relief for an hour a day.

The jazz aspect of the show
completely flew over my head when i was a child but it’s brilliance shines now that i listen as an adult. No two shows are played the same. Costa and his band are constantly riffing. The show is honestly a f-ing incredible work of art.
For me the problem has never been about outright breakage.

For IDEs, I have often observed: the whole is less than the sum of the parts. Trying to cram them all into one UI ends up removing a lot of capabilities, and it is always more difficult to add additional parts after the fact (since we should never assume all tools can be up-to-date with a changing world), compared to simply using the tools individually.

And IPEs are far more complicated than IDEs.
I read all the time about folks who become a VP/CTO and stop coding. Management skills are not coding skills. I know it. But I can't for the life of me figure out why folks hang up their keyboards and let their first super power go to waste. You can be a technical CTO from start to finish. Treat your team and the company like a service that needs active contribution, maintenance, and on-call support; and also, get your hands dirty building by yourself and with your team.
So, a hackier version of Tesla's autopilot? Sounds, uh, terrifying.

Cloudmark – A Registration-Free Cloud Bookmark Manager
Hey HN,

I’m excited to share Cloudmark - a project born out of my own need for a simple, no-signup solution to save webpages on the fly.

What it is:
Cloudmark lets you bookmark pages with one click using a bookmarklet. Just create a personal identifier, drag the bookmarklet to your browser, and you're set. No accounts, no fuss-just an instant, personalized cloud bookmark collection.

Why I built it:
I was tired of juggling multiple services with endless signups. I needed a tool that was as minimal and efficient as my workflow. Cloudmark lets me quickly save and categorize pages, whether I’m researching or just browsing. I built it for my own convenience, and I hope it makes your life easier too.

Quick start:

- Check out the demo: https://cloudmark.site/demo
- Read the Quickstart: https://cloudmark.site/doc
- See it in action with a neat interface and bilingual support.

Open source under AGPL-3.0 on GitHub: https://github.com/wesleyel/cloudmark

Would love to hear your feedback and thoughts. Enjoy the simplicity!
My wife and I have a daughter in the demographic of these shows, though she's a little young for Bluey. There's a YouTube (and now Netflix) show called Ms. Rachel for a younger audience that I'd put in the same positive category as Bluey.

We probably watch one or two hours of Ms. Rachel videos a day with our daughter. We've got several family friends with a household rule of "no screens at all for kids" who would scoff at that but their rule seems both draconian and technophobic to me. Our daughter has picked up many words and concepts from the show and we've learned a lot of the songs as a family and sing them when the context comes up (ex: "baby put your pants on..."). Ms. Rachel has been a hugely positive parenting tool for us.

Every once in a while, though, YouTube will try to autoplay some Cocomelon after a Ms. Rachel video and wow it's just absolute garbage. I think this article captures it well: it feels like slop engineered to keep young eyeballs glued to the screen with no higher purpose than increasing the number of engaged minutes.

Instead of "no screens," the more granular "you can choose from this menu of approved content on your screen for a reasonable amount of time per day" is the better parenting move for our family.
Show HN:I tried every app to stop doomscrolling, nothing worked. So I built one.

The Oriental Institute is now called ISAC for, ahem, reasons.
It should be in OCaml. This is why I think OCaml should be compilable to the Go runtime/ABI.
Ta wire looks interesting. Let me pick your brain here for a moment, my wife is looking to start SaaS soon, she is based in EU but intends to open both EU and Wyoming llc. Wyoming llc would sell B2C, EU llc would then invoice Wyoming llc monthly so she and her future employees can get paid. Since the eu country doesn't have tax agreement with USA the anon llc would be practically invisible to EU, and additionally as foreign owned llc with no employees I believe there is no tax in USA either? What do you think about this approach? Does your advice still hold; start with stripe, do the minimum to have llc working?
With enough cycles, dead virus you're successfully fighting off can be detected. It doesn't need contamination. For what it was used for, those were false positives that inflated the counts.
Can you explain in a bit more detail? I don't follow the connection you made.
By all means use tools like these, but be very careful, because they (and auditors that use them) will lead you into engineering changes that are not required for SOC2 and may not be what's best for your team. For instance: there is absolutely no need to set up PHI scanning or a WAF to get SOC2.
And why exactly would they do that?

> Everything you said is true for both of our programs, the only difference is whether or not it's hidden behind function calls you can't see and don't have access to.

This is a key difference between imperative programming and other paradigms.

> You don't really think that functional languages aren't appending things, using temp vars, and using conditional logic behind the scenes, do you?

A key concept in a FP approach is Referential Transparency[0]. Here, this concept is relevant in that however FP constructs do what they do "under the hood" is immaterial to collaborators. All that matters is if, for some function/method `f(x)`, it is given the same value for `x`, `f(x)` will produce the same result without observable side effects.

> What do you think ".filter(node => !node.isHidden)" does?

Depending on the language, apply a predicate to a value in a container, which could be a "traditional" collection (List, Set, etc.), an optional type (cardinality of 0 or 1), a future, an I/O operation, a ...

> It's nothing but a for loop and a conditional by another name and wrapped in an awkward, unwieldy package.

There is something to be said for the value of using appropriate abstractions. If not, then we would still be writing COBOL.

Suggesting that she was "bought off" by Russia without even the slightest bit of evidence is pure idiocy. Attacking people as being foreign agents for not fully falling in line with the orthodoxy is really what I consider to be "weird" and straight-up un-American.
This seems like an oddly specific take on this topic.

You can get a conflicting resource in a shell by typing 'npm start' twice in two different shells, and it'll fail with 'port in use'.

My point is that you can do not conflicting IPC, but by default IPC is conflicting because it is intended to be.

You cannot bind the same port, semaphore, whatever if someone else is using it. That's the definition of having addressable IPC.

I don't think arguing otherwise is defensible or reasonable.

Having a concern that a network service might bind the same port as an other copy of the same network service deployed on the same target by another host is an entirely reasonable concern.

I think we're getting off into the woods here with an arbitrary 'die on this hill' point about semantics which I really don't care about.

TLDR: If you ship an IPC binary, you have to pay attention to these concerns. Pretending otherwise means you're not doing it properly.

It's not an idle concern; it's a real concern that real actual application developers have to worry about, in real world situations.

I've had to worry about it.

I think it's not unfair to think it's going to be more problematic than the current, very easy, embedded story, and it is a concern that simply does not exist when you embed a library instead of communicating using IPC.
I like the idea and would probably reserve some if I still lived in the US.

But I don't think you should be setting yourself up against Powerwalls so directly. You're not really competing for the same market. The power storage solution for the 99.7% of us without Powerwalls is in fact Powerwalls (or similar) if you have solar panels/want a serious amount of backup power storage.

Your offering is not that. In fact, I can imagine some people with Powerwalls might want to add your product to their house as well, so no point in immediately turning off that 0.3% in your messaging.
You run PCR for cycles. You run it for 32 cycles? You've got a 4 billion times multiplication of the input signal. You see the problem? "Detectable" isn't a single ended specification with "PCR." You really do need to disclose how many cycles you ran.

Similarly there's ionizing radiation in your home. Right now. Flowing through you. If it's not above the background it's not interesting or material. So just saying "we found radiation" is equally meaningless unless you tell me that level in relation to something.

> is present or it is not.

Yes. And don't you use a /threshold/ mechanism to detect presence? Or you have tests so sensitive that a /single/ molecule or equivalent will deliver a reliably positive signal? I mean if it's that good why are you even doing PCR amplification in the first place?

> the standard is 30±10 cycles

The difference between 2^30 and 2^40 is massive.
How does this work, do I do the pose and squint or can I attach to a larger monitor? The example shows just the phone so I’m assuming I put it on the corner and then have to relay on a detector or color that says correct or not correct?

>>so there's no incentive for Karnataka's politicians to invest in it.

Do you seriously stay in Bangalore man? Because you don't sound real. Nearly every major politician has real estate and small industries stake in Bangalore. Politicians are NOT the problem, people are. People are not interested in good things. Their sole life is spent hoping other people have a worse life than theirs.

>>Urban management is not about political party - it's about bureaucracy

Most garbage picking vechicles, big tippers et al belong to local MLA's. Again do you even stay in Bangalore?

>>Bangalore is notoriously bad at urban planning and management.

My family has been in Bangalore for like a century. It was the best city ever. But you can't exactly have "urban planning" if migrants start growing 20% yoy for 30 years straight.

>>Bangalore on the other hand has remained underdeveloped due to land mafias.

Again do you stay here? Ever applied for a KIADB or BDA plot, waited for decades? Literally IT industry exists because of private land owner investments.

The show’s popularity has led to some people buying Blue Heelers as a pet for their kids… which will probably backfire because they aren’t meant to be house dogs

(Blue Heelers need an insane amount of exercise and can be pretty aggressive)

Heelers will demand four hours of an aerodynamic throwing stick tossed the length of a football field and back and then want a 5km run to the beach to cool down.

Failure to deliver can result in the destruction of everything you love.

Craigslist always seemed to me like the Dark Web, with all kind of people doing shady business, and this case is an amusing example:

Your subaru lanekeeping doesn't try to murder you? On a freeway or other uninterrupted left line, be in the leftmost lane. Start passing a semi trailer. The car wants to hug the middle, as usual, but I steer slightly to the left to be safe. After passing the truck, release grip slightly on the wheel.

Car Immedialy swerves into the right lane. At whatever speed you're going.

Our Subaru doesn't have lane change, so this is a fucking horrific bug that will kill someone by putting them under a semi.

I can repro this at most speeds on any road that meets the above condition.

If you think people only get upset about things for their own self interest, then I wonder what you think about social justice.

You have a Texas Sharpshooter Fallacy in your logic. A novelist is successful if they reach an audience. Once they find it, if they stick with it they will be successful. If they’re lucky then they might switch up genres without alienating their existing readers. But not everyone gets away with that.

A software developer has one audience and they don’t get to chose it. You and I write for our coworkers. If they don’t like it we have three choices. We can leave, we can change, or we can gaslight our coworkers that our code is just fine and they are the problem.

It’s the latter I’ve seen too much of, and even if you’re not a victim of it you’re allowed to be incensed for those who are. In fact you’re obligated to do so.
And in a real functional language like F#...

Can you describe why there's a big push for self checkout? I suspect there's a bigggg difference between countries, so this all sounds very alien. In my experience at Tescos (outside the UK) checkout has been great.

They tend to have a zillion aisles operating, with the cashier picking up and scanning every single item directly from your cart. At the exit there's always a 'check' but it's pretty farcical. Somebody glances at your cart, glances at the receipt, and then stamps it in about 0.5 seconds total.

The only downside is the requirement for self bagging (she simply puts the items right back in the cart - even if you bring bags), but that obviously wouldn't change with self checkout.

To me people pushing for self checkout sounds like somebody preferring self service over full service gas stations - I find it difficult to understand.
