Oh! There seems to be a caldera around this boiling river: https://i.imgur.com/VCgS4Xt.jpeg

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.

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.

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 :-)

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.

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).

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.

Example of bugs, posted last month on HN: https://www.bugsappleloves.com/

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.

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.

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.

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.

"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 =:-)

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!

"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"?

"a property of surfaces"

You can conceptualize Rayleigh scattering exactly like you did so it doesn't conflict with my explanation: as light hits the "surface" of nitrogen and oxygen molecules, it "reflects" (scatters) blue wavelengths.

Ok! Ping me when you get it updated - I am very curious :-)

I suppose our hobby is related to the hobby of ground-to-ground long-distance observation. Except we don't perform the actual observation, just the math of where it is theoretically feasible :-) In my case, years ago, I did exactly the same as Tom and Ryan: I algorithmically searched for the longest sightline. It was a weekend project just to satisfy my curiosity. Then last year, Tom and I kinda connected informally over this hobby.

Well this is just a personal website, so it is has much (or as little) information as the owner wants to put up. The legal notice page (in German) tells you it's the site of a certain Dr. Ulrich Deuschle: https://www.udeuschle.de/impressum.html

I dislike with passion the answer "because Rayleigh scattering". When someone asks why, especially if a child asks, the default answer should be the simplest correct answer:

Because it's the color of the atmosphere, specifically nitrogen and oxygen! It's technically correct to state this.

Gasp! But aren't nitrogen and oxygen usually described as "colorless"? Well, yes but... If they were perfectly colorless, the sky would be black. It's technically more correct to describe them as nearly colorless and very slightly blue. Very slightly because you need to see through kilometers of atmosphere to perceive the blue. It doesn't matter if the color is caused by absorption, or reflection, or (Rayleigh) scattering of certain wavelengths. The "color" of an object is simply the color you perceive with your eyes. If you perceive blue, it's technically correct to say its color is blue.

It's like saying plants are green because green is the color of chlorophyll. And in the case of chlorophyll, the color is caused by absorption not by scattering. But the physics is irrelevant. Green is its color.

Q: But sunsets/sunrises are red & orange not blue! A: the simplest answer is: color of an object can change under different light conditions. Specifically in this example, when seeing the sun through not kilometers but hundred of kilometers of atmosphere, all the blue-ish wavelengths have been scattered in random directions so only the red-ish wavelengths remain, thus the atmosphere is illuminated by progressively redder and redder light as the photons travel longer and longer distances through the atmosphere.

Ok that makes sense, thanks for the reply! Maybe document this "percent or so" error in the FAQ since it is about 16 times bigger than the (other?) ~0.0685% error you mention that can be caused by the AEQD reprojections.

Reply to my edit #2: I realize the "To" point 41.0181,77.6708 is just the coordinate of the center of the 1°-wide horizon line. The actual farthest visible point according to your analysis is probably this peak in the west half of the 1° field of view: 41.014862, 77.647818 So I retract my comment about the error being "clearly" on your side. However this does indicate that we definitely calculate things differently. In my analysis Pik Dankova at 41.059542, 77.684808 which is a few km further can actually be seen and that's the source of our differences. I don't know who is right.

For a 3D rendering of the longest sightline, see this direct panorama rendering: https://www.udeuschle.de/panoramas/panqueryfull.aspx?mode=ne...

Note that technically my link is a slightly longer sightline (longer by 7 km).

Hi Tom it's Marc, I'm glad to see you finished your sightline project ! Any clue why you report the longest sightline as "530.8 km" when it seems to be actually 538.1 km? That's what my code calculated (https://news.ycombinator.com/item?id=45512970) that's what Dr. Ulrich Deuschle also calculates (https://www.udeuschle.de/panoramas/panqueryfull.aspx?mode=ne...) You, Deuschle, and I all use the same DEM data (https://www.viewfinderpanoramas.org/Coverage%20map%20viewfin...) and the same refraction coeff (0.13), and nearly the same camera height (1.5m for me, 2.0m for Deuschle, and 1.65m for you—and these differing heights make no difference given the coarse DEM resolution). Something must be slighly off in your computations? Or do you think both Deuschle and I are wrong?

Edit: to be clear the difference stems from our coordinates. Our starting points are:

41.059167,77.683333 (me)

41.0181,77.6708 (you)

And our end points are:

36.295364,78.755593 (me)

36.314,78.7654 (you)

Also I calculate the distance assuming the Earth is spherical (which gives 538 km) not the standard geodesic (which would give 537 km).

And in the DEM data I measure the distance from the center of a cell to another (not the edge), while measuring from edge to edge may explain a difference of at most 0.1 km as the DEM resolution is 3 arcseconds.

So clearly we disagree on the coordinates of the exact actual sightline as we have a 7 km difference :-)

Edit #2: clearly the error is on your side. I should have checked this first, but the coordinates you give for the "To" point (41.0181,77.6708) land in a valley with the south view completely blocked so it's impossible to view 500+ km south as you claim. Look at where the marker lands on this Google Maps Terrain: https://maps.app.goo.gl/PgBWxi31WZC6vk3V9

Whenever this discussion comes up I liked to point out that even in the computer industry, prefixes like kilo/mega/etc more often mean a power of 10 than a power of 2:

I gave some examples in my post https://blog.zorinaq.com/decimal-prefixes-are-more-common-th...

Nothing was unnecessary since the goal was having fun & learning.

Very impressive build! It's amazing what one can do thanks to CNC and FLPCB manufacturing services readily available to any motivated hacker.

One tip for the author who noticed the camera being warm: measure its power consumption, and compare to an unmodified G9ii. Especially because you noticed it drains the battery relatively quickly(!) This is a glaring "connect the dots" situation to me. The root cause might be something very stupid. For example when you removed the microphone jack, the camera thought a microphone was connected, so it activated a microphone nenu. But given the extensive number of mods you made, it's possible you are making the firmware think some accessory is connected—could be anything: (light) flash, external screen, USB gadget, JTAG reader, SD card, etc. So it's taking a code path to initialize the device, but it fails because the device is not present, and it retries repeatedly, thus entering a retry loop that's causing excessive CPU usage... That wouldn't surprise me. You are running a G9ii that's unique therefore a rare software code path like this would not happen on a standard G9ii and would never have been fixed by the developers.

Edit: I see the author measured power here: https://www.reddit.com/r/Lumix/comments/1oif3jp/how_much_doe... and to my eyes, these seem really high numbers. For example in video playback mode he measures 340mA, so 2.45W (battery is 7.2V nominal). The standard G9ii battery is 16Wh that means it would last only 6.5 hours playing back video. Compare this to a Pixel 9 phone: 18.3Wh battery and can playback video for 15 hours (I believe these are benchmark numbers reported playing back 4k H264 video, probably in a similar-ish format to the G9ii in terms of bitrate, etc). Plus the phone is at a disadvantage as it has a bigger, more power-hungry display. So it seems to me his G9ii consumes twice as much power as it should, if not more... If anything a pro camera should be more optimized than a general-purpose consumer device when playing video!

"pushing 996"

What does this mean? You mean they have close to 1k employees? Odd typo or odd way to say it.

Tx fees make up a bigger and bigger fraction of miner rewards over time.

"Bitcoin's security inevitably weakens over the coming years due to diminishing miner rewards (denominated in BTC)"

That's incorrect. Security scales with USD-denominated rewards, not BTC-denominated. And there are 16 years of real-world data showing they have been generally increasing, so a healthy sign that the Bitcoin experiment is working:

https://newhedge.io/bitcoin/block-reward-per-block

And not only that, but rewards are still expected to stabilize even when measured in BTC (thereby not relying on an increase of BTC's price) as they are progressively composed more and more of tx fees instead of newly mined BTC.

It's puzzling to me why some still don't understand the systemic incentives that make all this work as it has for 16 years and counting...
