mrb··on Anthropic reported diary entry to police, woman faces felony charge
Florida statute 836.10 puts the bar at the "sending, posting, or transmission of, a [...] record, in any manner in which it may be viewed by another person"

I think the defendant could successfully defend themselves by claiming they did not know (or intend!) the message could be viewed by another person, as they were plainly using it as a private diary.

mrb··on Improper redaction reveals Google Data Center water and electricity usage
What the water figures show is that water usage is not the problem of these data centers. It's a drop in the bucket, literally. Yet another way to see it is that given the average weather in Lincoln, NE (29 inches of rain annually) it rains 480 million gallons annually on the 600 acres campus that Google's data center is located on. So it would be possible to collect only 3% of this rainwater, and it would be enough to cover all their water needs. Water, at the local scale of this campus or city, is an infinitely renewable resource.

Other issues than water are far worse, like pollution associated with the manufacturing and running of all the data center gear. Water is not the issue.

mrb··on Improper redaction reveals Google Data Center water and electricity usage
Yes. As another comparison point, 13 million gallons per year amounts to 24 gallons per minute which is about 5 (five) bathtub faucets running 24/7/365.

The water bill alone would be only $100k/yr assuming average US domestic rate of $8 per 1000 gallons.

mrb··on Owed a billion dollars in Nvidia stock
"You didn't care to have any inkling of memory of the vesting schedule in 1996, or just to double check and "wrap up" the financial details of that agreement after the work was done?"

Give the guy a break. It was a check of 700 bucks for exercising shares in a small (at the time) company that was not even public. Most people would probably not notice the error in the 1 year vs 4 year exercise schedule. Especially because 4 years is the standard, so that seems rather normal to agree to that even though it was an error and differing from the original offer.

mrb··on LG denies TV spying claims, says tracking and snooping concerns 'not true'
As usual, the key to explain the discrepancy between LG's claims and the paper 2024 is in the wording. Read carefully: LG claims it "does not collect screenshots, screen recordings, video recordings, voice recordings, or other audio recordings from the TV.". IOW they are making the technical distinction between "fingerprinting" and "screenshots or recordings".

And specifically, they are not confirming or denying that video fingerprinting are done.

What I think is likely is, as the paper states, that they fingerprint both audio and video. Upload both to their servers. But they end up using only the audio fingerprint for ACR. In this situation, neither LG's statement, nor the paper's statement, nor the GamerNexus folks's claims are incompatible with each other.

It even makes sense from a technical standpoint: it is far easier to uniquely identify content by audio than by video, as a fingerprint of a few milliseconds of audio is pretty darn ideal, compared to fingerprinting even a single video frame which has hundreds of ways it could be compressed depending on codecs, bitrate, resolution, etc.

mrb··on It takes 5 cloud services to hear my doorbell
We all understand your point: you believe the feature is unnecessary in the first place, without any understanding of my particular situation why I actually need it.

Regardless, this is irrelevant to the point of this entire thread, which is that it's possible to design a device, as I did, that is vastly simpler than commercial doorbells allowing user-customizable chimes.

mrb··on It takes 5 cloud services to hear my doorbell
You still fail my challenge: design a wireless doorbell that has a user-configurable chime (eg. MP3 file provided by user), in a way that uses less software or less hardware than mine. You couldn't.

Then I want you to justify why commercial products offering this feature have 10-100 times more code or 10 times more complex hardware just to do what my doorbell does :-)

mrb··on It takes 5 cloud services to hear my doorbell
You completely missed the part that the chime needs to be user-configurable, ie. play a custom MP3 file.

You don't provide that.

mrb··on It takes 5 cloud services to hear my doorbell
"The sound is not customizable"

This is EXACTLY the problem! Try finding one that I can customize with my own chime and you will only find expensive, unreliable, over engineered stuff.

mrb··on It takes 5 cloud services to hear my doorbell
It would be over engineered if one could design a system providing similar functionality using less hardware and less software.

I challenge you to design a wireless doorbell that has a user-configurable chime, in a way that uses less software or less hardware than mine. You couldn't.

In fact, if you did market research like me you would find that 99% of similar products have vastly more complex hardware or software or services being them. They break when there is no Internet. Some work without Internet but don't work when the local Wi-Fi is non functional. They don't immediately get back online after a power outage. They need regular software updates during which the chime can't play. These are over engineered things. Not my product, because mine has none of this complexity or faults.

mrb··on It takes 5 cloud services to hear my doorbell
That is exactly over engineered crap I want to avoid. I don't want my doorbell to depend on networking or a full blown Linux stack.
mrb··on It takes 5 cloud services to hear my doorbell
The requirements are not over engineered. They are what they are. Wireless and configurable chime. They are fixed parameters.

But my implementation of these requirements is absolutely not over engineered. I argue it is the simplest and most reliable it could be done.

"You could have bought a bell.."

No because similar commercial products were either out of stock or not compatible with my AC voltage.

mrb··on It takes 5 cloud services to hear my doorbell
I am super sensitive to over engineering. For my doorbell I wanted something that lets me play a custom bell sound. You would be surprised that 99% of the solutions out there are complete over engineered stacks that depend on wifi devices, Internet access, connecting to various cloud services... So I built my own: a basic wireless button sends a radio 433 MHz signal, and my receiver is plugged inside the house and triggers an off-the-shelf playback PCB module that reads an MP3 off an SD card and plays it on a speaker wired to the module. No Wifi, no Internet, no cloud, no apps. And the rare times I want to change the sound, I update the MP3 on the SD card.

Edit: there are very, very few products on the market designed as simply as this, just an R/F signal triggering local playback. I think the only commercial doorbells designed like this I found were an out-of-stock product, and a UK device designed for 230V that would have required a bulky adapter to work for me in the US.

mrb··on Shanay-Timpishka, a boiling hot river 700km from the nearest active volcano
Oh! There seems to be a caldera around this boiling river: https://i.imgur.com/VCgS4Xt.jpeg
mrb··on Shanay-Timpishka, a boiling hot river 700km from the nearest active volcano
It's located here for those wondering: https://maps.app.goo.gl/js7miFSkRBa86t15A?g_st=ac

If you click on the little resorts/hotels/towns around the area, there are many pictures and videos of steam rising of this little river. It's obvious the area is well frequented by tourists. Not as remote as I thought it would be.

mrb··on Show HN: I replaced a $120k bowling center system with $1,600 in ESP32s
Don't dismiss the OP so abruptly. IMHO he is convincingly making the case that there is likely a business opportunity for something between a $120k off-the-shelf system and $1.6k in DIY hardware.
mrb··on Irish datacenters now guzzle 23% of the country's electricity
Or Ireland can import electricity from France TODAY as we export on average 10 GW continuously, and most of it is already generated by nuclear :-)
mrb··on Irish datacenters now guzzle 23% of the country's electricity
Ah the old "country's worth of electricity" comparison... Keep in mind that Ireland's entire electricity needs could be covered by a one nuclear power plant (3.8 GW with 4 reactors). IOW, you could offload all Irish datacenters by connecting them to a single nuclear power reactor (~900 MW), a small building that has a footprint of under 50 x 50 meters for the reactor, and another of 100 x 50 meters for the generator.
mrb··on Goodbye Visa and Mastercard: 130M Europeans switching to sovereign payment
Yes Wero and Zelle are similar: real-time payment systems, where money is sent directly from bank account to bank account, and recipients are looked up with a convenient ID (a phone number, or an email).
mrb··on I love Linux, but I can't quit Windows
TBH your problem sounds like a hardware issue. Maybe the PC's new location is warmer due to a more enclosed space, triggering more unrecoverable hardware faults.

mrb··on France pulls last gold held in US
As a French speaker, I looked up French sources and found https://www.lesechos.fr/finance-marches/banque-assurances/st... - here is a snippet translated to English below. But many more references can be found by googling "opération vide-gousset".

1963: Operation Empty-the-purse ("vide-gousset")

It was also by warship that De Gaulle planned to conduct "Operation Empty-the-purse" in 1963, the code name for the repatriation of French gold deposited at Fort Knox in the United States (1). More than 1,150 tons—the result of converting French dollars into gold, a decision made by De Gaulle in response to the lax monetary policy of the United States—were being used to finance a growing trade deficit through the printing of money.

Valéry Giscard d'Estaing, then Minister of Finance, recounts (2): "De Gaulle was getting impatient and asked me at every meeting: 'So, has that gold finally come back?' One day, he told me: 'We need to move much faster: we're going to send the navy cruiser 'Colbert' which will bring back all the gold that's still there.'" “I told him that if we did that, we would alienate American public opinion forever.” Ultimately, De Gaulle abandoned the Colbert plan, and French gold returned from the United States in small quantities. Not for very long, it's true. The events of May 1968 and the ensuing monetary crisis depleted the reserves, which fell from 4,650 tons to 3,150 – 1,500 tons had crossed the Atlantic again to defend the franc, which De Gaulle refused to devalue.

mrb··on Mayor of Paris removed parking spaces, reduced the number of cars
I live in Paris and bike nearly every day, with my electric bike, or sometimes the city's velib rental bikes, sometimes private rental bikes (Uber, Dott, Voi). I love the drastic push to add more bike lanes, and reduce car lanes. I don't own a car in this city. Don't need one.
mrb··on The 49MB web page
Let's play a fun prediction: I ask HN readers what will be the page size of NYTimes.com in 10 years? Or 20 years?

Want to bet 100 MB? 1 GB? Is it unthinkable?

20 years ago, a 49 MB home page was unthinkable.

mrb··on Put the zip code first
Yup. I typed my French ZIP code (code postal) and this guessed a US city...

But the author has a point. Combine it with some approximate country-level geolocate of the web client and this would work perfectly 99% of the time modulo edge cases like VPN users.

mrb··on Personal Statement of a CIA Analyst
"Someone who hated computers so much that she had the secretary print out her emails so she could read them was interrogated for hours about hacking into Agency networks [...] there was often a gross mismatch between a person and the accusations made against them."

Well, isn't it expected? If I were a double agent, faking that I was so computer illiterate that I ask my emails to be printed out would be the perfect cover for my hacking =:-)

mrb··on I want to wash my car. The car wash is 50 meters away. Should I walk or drive?
Mistral's Le Chat also fails spectacularly. Although interestingly it assumes that the "walk" option means you are carrying washing supplies back and forth in order to wash the car while it's parked at home. I wonder if the other models assume this is what you mean, IOW they may not know how a "car wash" normally operates.

"""

Great question! Here are a few things to consider:

If you walk: It’s only 50 meters, so it’s a very short distance—less than a minute on foot. You’ll avoid getting your car dirty again on the way to the car wash. It’s a quick way to stretch your legs and save a tiny bit of fuel.

If you drive: It’s so close that driving might feel unnecessary, but it could save you from carrying any supplies (like vacuum cleaners or cleaning products) back and forth. If the weather is bad (rain, extreme heat, etc.), driving might be more comfortable.

Verdict: Walking is probably the easiest and most practical choice for such a short distance, unless you have a specific reason to drive. What’s the weather like where you are? That might help decide!

mrb··on Fix the iOS keyboard before the timer hits zero or I'm switching back to Android
"caved to the blue bubble pressure"

As an Android user, I truly don't understand this "pressure". I exchange SMS/MMS with various users, some Android, some iPhone. I am in group chats with both Android and iPhone users. I feel there is no major issue. It's interoperable. We all see each other's emojis/photos/videos/etc. There are only minor technical rough edges: for example an iPhone's user emoji reaction sometimes (not always?) shows up as separate text instead of the emoji appended at the bottom of the text bubble... And I am pretty sure videos are sent in a lower quality. But is any of this really enough to cause a "blue bubble pressure"?

I asked ChatGPT to explain but only got this vague answer: "Group chats with a mix of iPhone and non-iPhone users can be less seamless (e.g., lower video quality, no read receipts, or issues with group chat features)."

I had to open my texts to check: I indeed have read receipts when texting Android users, but not iPhone users. And this is funny but up to this very second, I had never noticed this difference... because, at least to me, read receipts is such a minor feature that I rely on very infrequently.

This leaves me still as perplex: why the "blue bubble pressure"?
