I'd love to have better backup power but I'm skeptical of huge lithium batteries inside my home.

Here's a tiny scooter battery going on fire spontaneously: https://www.youtube.com/watch?v=ld00r-tEEJ4

Can we use something other than lithium for home battery backups? Weight isn't really a concern.
GP's point is that having SSO and protected git branches _is_ starting the SOC2 process.
You should address that with exterior grading and diverting gutter run off so far away from the structure that it can’t seep back toward your basement.

If water can get in, it will. And it will do it when your sump is not operating.

If you’ve already addressed it externally and you’re still seeing water come in, then you didn’t address it completely. End state should a totally passive system where the sump never even fills.

And if that doesn’t work, sell the house and get one on top of a hill!
Thanks, updated the title to reflect that.

Show HN: A crowdsourced table of 45 system design questions with solutions
Whatever design wins should also be available as a standalone device (maybe even something that can be installed inside an existing enclosure if there’s room and maybe even in a circuit breaker format) and not just a meter ring adapter. There are users who, for various reasons, cannot use meter ring adapters as switches. For example:

- Some services cannot be switched at the meter ring. This includes services that use a current transformer separate from the meter. (As far as I know, this includes all services over “Class 320”.)

- Some apartments aren’t separately metered. Fortunately, this is rare.

- Some users will want to back up only part of a service.
I've never heard anything about comma.ai's safety. I wonder if it's just not high profile enough to have been involved in public incidents?

Yes. It is just a broken process or overworked recruiter, nothing personal. Yes, it is rude but that is life.

Use them as opportunity to practice your interview skills. If this time they make an offer and you have another offer, use that to negotiate hire salaries. And if you decide to go with the other company, ghost this company.
If there are two ways to say something, then people will find ways to make their choice of method into speech as well.

To me and my style of coding, there's a difference of intent between the two. A ternary connotes a mere computation, something that should have no side-effects. A conditional connotes a procedure; the arms of the conditional might be expected to have side-effects. (And the case of `if (_) return` or similar are pure control flow guards; they neither compute a value nor perform a procedure as such.)

It's not just about where the symbols go on the screen.

> what happens when those economic and political elite are too extreme and are overthrown

Regimes fall when subsets of the elite decide to defect to the opposition.

For example, Hosni Mubarak fell not because of protesters in Tahrir Square, but because Sisi didn't feel like shooting protesters at that time for Mubarak's sake (Sisi had ambitions). If Sisi and the Egyptian military didn't decide to return to the barracks, the Arab Spring in Egypt would have never happened.

The only solution to this is by actually cultivating multiple different factions within those elites. Yet this is something the US is not good at anymore because this kind of knowledge and understanding requires significant cultural background, and State Dept hiring regulations prevent people of the same ethnicity from working on relations for those countries.

> Consider the various examples of regime change and/or support for dictators/authoritarians enabled by the United States in South America and the Middle East

The most notable one in the post 1971 era is Iran 1979 where US cultivated the secular Shah's government and military leadership, but not the organized Shia clergy. If the US had cultivated Khomenini, we wouldn't have been in such a severe situation. The French on the other hand engaged Khomeini and Shia clergy, and it helped ensure that France could maintain relations until the sanctions regime began in the 2010s.

By the 1990s, US foreign policy in Latin America changed to democracy promotion due to the same points you brought up, and that caused Honduras to switch in favor of China after corruption investigations threatened their leadership, and Nicaragua switched in favor of China due to pushback for democratic backsliding in 2017-18.

It's not that they're expected to differ, it's that they do differ. If you look at oxygen isotopes from meteorites the ratios are all over the place. Also, Mars meteorites (which we know are from Mars because of noble gas isotope ratios being the same as measured by Viking landers) have different oxygen isotope ratios than Earth.

All rocks on Earth and on the Moon have ratios that lie on a single line, the Standard Mean Ocean Water (SMOW) line.

BTW, the fact that meteorites have a wide variety of ratios that don't lie on a single line indicates meteorites derived from asteroids did not come from a single parent body. There was no planet between Mars and Jupiter that exploded to form the asteroid belt, bad science fiction stories notwithstanding.

It’s also wild that I didn’t realize at first if “giant escalating crisis” was referring to the Trump administration or climate change.

A friend of mine briefly owned* the autonomous cross-country driving record, using Comma AI. I forget the exact autonomous percentage, but it was above 99%. I want to say 99.4x% but I might just be thinking of Ivory soap, haha.

The record, for reference, uses a traditional Cannonball route from Red Ball Garage in NY, to Portofino Hotel and Marina in Redondo Beach, CA.

2850 miles of American interstate plus a bunch of surface streets at the start and end. All with under 20 miles human assisted.

You said, and I agree, that people have become "extremely propagandized/delusional" due to prior tech development; why would AI tech have different outcomes?
interesting read but lacking fairness, since "weakly coupled wads of s**" is all at once, pejorative, lacking useful meaning, and strongly underestimating the advances in software over 20+ years that are in said wads.. Architects don't like a lot of things..
The reason for that is two-fold. Firstly, there’s a tax accounting lobby in some countries (ahem, TurboTax). Then there’s the fact that when people are afraid they could make a mistake, they tend to pay more, and generally might not even think about what they are paying for in the first place.

HN has always been a curated/moderated site. I'm not really sure what "censor" means other than that, at least in the context of an internet forum like HN.

We basically moderate posts that break the site guidelines (the ones that we see, at least).

My view on this is shaped by the situation in Asia, and in particular Bangladesh where I’m from. The former Bangladesh PM, Sheikh Hasina, was a despot but also had a real democratic mandate, with 70% approval according to a polling by a U.S. organization: https://www.cfr.org/blog/new-bangladesh-survey-hasina-remain.... The U.S. has giving her a hard time, however, for human rights issues. Which certainly existed—but which most people weren’t concerned about.

I’ll leave aside my conspiracy theories about how much Anthony Blinken had to do with Hasina being overthrown last year. But we have a new government promising more liberalism but the security situation has deteriorated: https://www.aljazeera.com/features/2025/3/4/gotham-but-no-ba.... Holding fair elections will be impossible, because the interim government has a tremendous incentive to ban Hasina’s party, which has long been the most popular party.
American fridges are generally much bigger than European ones. Mine is something like 27 cubic feet, which I understand is around double the size of an average European fridge.

I don’t think I’ve ever lost power for long enough that I lost anything in the fridge though, but there are parts of the country with a much less reliable grid (usually due to severe storms or other natural disasters).

> No one seems to know, exactly.

The problem is that we've made this intellectual laziness acceptable. Nobody knows exactly? We have pretty good ideas; we know the difference between legitimate media and propaganda; we just need to encode that in English in specific rules.

And before that, we need to get the people who benefit from propaganda, and therefore defend it, out of power. Look at the widespread, and effective campaign to shut down anyone studying disinformation. The problems with letting things like that fester and not doing anything - which is what we've done, mostly - is that people in power become invested in it.
What is the experience driving the car? "You are still driving the car"—is it akin to tesla's autopilot, or is the experience difference? In some 3 y'o videos I see individuals driving without hands on the steering wheel—not sure if that is what the experience is like day to day with the device (?).
Maybe someone else was sabotaging his work. Is it possible to cherry-pick one paragraph from it that is well-written and technically sound? Because I gave up after Chapter 1 and the beginning of Chapter 2. Maybe you could ask Alex what he thinks of how the book turned out and post his answer here?

I agree that it's mean, and I feel kind of bad about it, but I think the interests of the hundreds of people who are apparently interested in reading a book about software-defined radio outweigh the interests of the four authors to not have their feelings hurt. The problem is not that they've written this colossal pile of garbage; there's nothing wrong with that, and it's often the first step toward writing something worth reading. The problem is that that pile is being promoted (by Analog Devices, no less) as a useful way to learn about software-defined radio.
There is nothing that will make me throw something on Craigslist faster than a loud fan. We built the battery with the customer in mind. It has fans but they are larger, RPM controlled and measure all internal temps to keep the noise to a bare minimum.

In just this piece alone he makes several objectively false and/or narrow-minded statements, even back when he wrote it.

I'm holding various stocks, most of which I plan to hold for some decades until I retire and start drawing down.

For long term holdings volatility doesn't matter much - I'm generally happy to take more volatility in exchange for higher expected returns. (Or else, I wouldn't be in stocks at all, I'd be in GICs and treasury bonds.)

(That all said, I'm not long on Tesla; I have individual short positions to roughly neutral out my Tesla holdings within ETFs I hold.)

From the Pila website: “In 1880, Italian physicist Alessandro Volta built the world’s first electrochemical battery — the Pila di Volta, or voltaic pile.

Inspired by nature’s own electrical engineers, he stacked metal plates to mimic the organs inside electric eels, transforming a wild phenomenon into a scientific breakthrough.

Like Volta, we’re reimagining energy storage with nature as our guide — building a smarter, more adaptable battery system designed to bring peace of mind, control, and energy savings to every home.”

Yup exactly, the battery can be easily setup to charge at night and discharge during the day. It can also charge while you have solar and discharge when you don’t.

With hash-based signatures, hybridization isn't required. They are the most powerful signature scheme approach by far. The security assumption hash-based signatures rely on is also shared with every other signature scheme (hashes are what are signed). Other schemes come with additional assumptions.

It's unfortunate that hash-based public key exchange is not practical. Merkle Puzzles require 2^n data exchange for 2^2n security.
Fair. I wasn't actually responding to your initial comment or defending the specific claims of the person that you were replying to—just responding to the person who mischaracterized the source of most anti-Mozilla rhetoric.

So yeah, my beef with the VPN as a solution for monetization is different than OP's, and I wouldn't try to defend a position that claims that it's an active money sink. My argument is just that unless they have an extremely favorable deal with Mullvad it's most likely an extremely inefficient way to make money from someone like me who would be straight-up donating monthly if it were an option.

Yep! Pila qualifies for the 30% Federal Investment Tax Credit (ITC) under the Residential Clean Energy Credit if your Pila system exceeds a total of 3 kWh capacity through either:

One Pila battery plus a Pila Expansion Pack (1.6 + 1.6 = 3.2 kWh)
The US strategy seems to vary widely by store. Some observations:

Target and Whole Foods have minimal oversight and the machines are efficient and permissive. Delightful!

Costco has machines that are not permissive and complain a lot. I find this odd, considering that Costco is members-only and double-checks everyone when they leave.

IKEA has one employee per 1-2 machines. The machines are terrible. The scanners are unreliable, and the machines are slow beyond belief. I suspect they’re accidentally quadratic (with a bad constant factor), and I’ve had to pay part way through and start a new transaction to make forward progress at a reasonable rate. The employees might be there more to babysit the machines than to deter theft.

” Where will America’s new “Freedom Cities” be built? It seems quite possible that the Network Staters want to build them in our national parks. On its website, the Freedom City Coalition notes that 28 percent of U.S. land is “federally owned and ready for innovative development.” It doesn’t specify what kind of federal land is “ready” for this “innovation,” but most of the government land that isn’t used for farming and energy development is used for wildlife conservation.”
