while_true_··on Lunar Terminator Paradox
Makes perfect sense to me. When starting the shortest path for a flight from San Francisco to Tokyo, you don't point the plane toward Japan, you point it towards Alaska.
while_true_··on New Satellite Engine Could Use Earth's Atmosphere to Stay in Orbit Indefinitely
The Earth's upper atmosphere is delicate. It's already being disturbed with rocket fuel residue and particulate space junk. Vacuuming up air and ionizing it risks putting the upper atmosphere even more out of balance.

while_true_··on Universal health coverage could save $1T and 114k lives a year: study
They had 59 votes from Democrats for the public option, not single payer. Public option is to let people choose either a non-profit government insurance plan or private insurers. They needed 60 votes to break a Republican filibuster. Joe Lieberman (Ind-CT) said he would filibuster the public option but would vote for the ACA without it.
while_true_··on Magnitude 7.7 Earthquake – 68 km NNW of Ende, Indonesia
Interesting this earthquake struck shortly after a solar eclipse, implying significant spring tide forces were present. The earthquake occurred near dawn, when the sun/moon pair, Indonesia, and the Earth's core formed a right angle to each other, creating tidal tension forces on the crust.

Tidal forces have been linked to the Dec. 26, 2004 Sumatra earthquake. This paper claims there's a significant link between tidal forces and earthquakes in the region (https://doi.org/10.1029/2006GL027074). The authors conclude "The observed relationships suggest that the cyclical crustal flexing, which will be at a maximum at full or new moons, might provide sufficient extra force to a plate-boundary region already on the point of rupture to trigger an earthquake that was ‘waiting to happen’."

while_true_··on Plug-In Solar Panels Starting to Sprout in U.S. Backyards
California has huge amounts of excess renewable generation nearly every day, especially in spring and fall. Last April the grid operator curtailed 1.47 million MW/hrs of renewables, or about 2 GW per day. That's excess power the grid did not accept due to no demand. (source: https://www.caiso.com/documents/key-statistics-jul-2026.pdf)

In my mind the ideal solution is in addition to daily BESS time-shifting is seasonal time-shifting: long term storage of April excess for use in July.

while_true_··on Ask HN: How are you using AI to learn?
AI, when used in an organized and structured way, is excellent for learning a language. For example:

1. Ask AI for the 10 most commonly used verbs in ordinary daily speech in language X.

2. Prompt AI: generate 4 short sentences for each of the 10 verbs at the A1 (beginner) level. Provide the sentences in .csv format compatible with the Anki flash card program.

3. Import .csv into Anki. Study your 40 cards.

As you advance you can do much more like having conversations with AI avatars, transcribing videos, translating text, generating audio clips, and so on.

Dr Taylor Jones, a PhD linguist, goes into greater detail here: https://youtu.be/xQXiSGDXknA?

while_true_··on Exercise Erased Half the Molecular Signature of Muscle Aging
Many elderly die primarily from sedentary disease, not from aging itself.
while_true_··on [dead]
Yes, but the bars shown don't match the NOAA data source I found. Also, if the chart goes to 2025 then why was the 1961 to 2020 period chosen for the average? Doesn't make sense.
while_true_··on [dead]
Why was the period 1961-2020 chosen? Why omit the years 2021 to 2025? The X user appears to be a climate denier and is cherry-picking data to support their agenda.

In 2020 the average US temperature was 55.7 F. In 2025 it was 57.8 F, an increase of 2.1 F in only five years. The cherry-picking conveniently excludes 2022 when the US set an all-time record of 34 days where the max temp exceeded 100 F.

while_true_··on Microsoft emails Windows 10 holdouts: Fine, keep your old PC another year
Too late. My household's desktops and laptop are all on Debian/KDE Plasma linux. Glad I switched, I think Plasma is a better more customizable "windows" than Windows is.
while_true_··on Microsoft Needs Windows Lite
Too late. In my household there are 4 desktops and one laptop. Wiped Windows and installed Debian with KDE Plasma. For our use it's a better "windows" than Windows. Not going back.
while_true_··on Solar in California surpassed natural gas in the first five months of 2026
The rapid addition of 16 GW worth of batteries play a significant role in reducing demand for natural gas, especially in summer. On a hot day with high A/C demand batteries can meet the demand around sunset, reducing the need to dispatch gas peaker plants.
while_true_··on Solar in California surpassed natural gas in the first five months of 2026
California often produces over 100% of the energy it uses, is sometimes a net exporter of power, and often curtails in-state solar and wind. For 2026 the import limit is 11 GW, so in-state production won't be less than about 81% at any given time.

while_true_··on "Don't You Just Upload It to ChatGPT?"
Yes. It's as if they think AI will forever be LLM only and won't develop world models that incorporate current state assessment, dynamic next-state prediction, cause-and-effect reasoning, object permanence, etc. I'm not in the AI industry but I assume there's got to be lots of research and work being done on this.
while_true_··on Social Security Now Expects Shortfall Earlier, in Late 2032
Put a tax on AI for each human employee it displaces. Estimate the human labor equivalent of AI each year and levy a tax to replace Soc Sec and Medicare revenue no longer received. Benefits need to be funded for existing retirees and they need to be there for younger generations too.

Makes me wonder if WWV will meet the same fate.
while_true_··on GPT‑5.5 Instant
Correct. I have the $20/month plan and I just checked, the default is 5.3-instant. I can manually switch it to Thinking is 5.5. I also have it set to auto-switch.
while_true_··on Nocord HF – A discord style FT8 client written in Golang
IIRC there are other WSJT clones that translate and consolidate the code to avoid the awkward mix of Fortran, C, C++ into one language but they have the same problem, they aren't as good at weak signal decodes. In WSJT-X maybe there's some sort of probability-based decoding in addition to the use of Costas arrays to fill in the blanks when partial signals are received?

while_true_··on US and TotalEnergies reach 'nearly $1B' deal to end offshore wind projects
In 2026 utilities will install 86 GW of new generation, of which only 6 GW will be natural gas. The other 80 GW will all be solar, wind and battery storage. Utilities are doing this because of economics. Environment is secondary. Even oil and gas rich Texas has been aggressively adding solar, wind and battery.
while_true_··on US and TotalEnergies reach 'nearly $1B' deal to end offshore wind projects
Wind and solar are consistently the cheapest forms of new energy generation. Pouyanné knows that. He is being a politician here, saying what he knows will play well with the current administration. When in Rome...
while_true_··on US and TotalEnergies reach 'nearly $1B' deal to end offshore wind projects
NY Times phrases it as a reimbursement to TotalEnergies for relinquishing wind leases that they paid for. The US made the reimbursement contingent on them investing in fossil fuel projects. "The deal is an extraordinary transfer of taxpayer dollars to a foreign company for the purposes of boosting the production of fossil fuels."

Total waste of $1 Bil of taxpayer dollars. If the oil and gas industry want to shut down wind projects let them pay for it.

>> The west coast is the only part that relies on middle eastern oil. And a spike in prices will just get them in line and connected to the rest of the shale powered system.<<

Californian here. There is no discussion or any desire to build an oil pipeline from TX/LA across NM and AZ to deliver oil to refineries here. Ha, if you think the Keystone XL pipeline was controversial... it'll never happen.

Calif produces about 20% from its own but tired wells. Some oil is imported from the Middle East but larger volumes come by ship from South America and Alaska.

while_true_··on Plasma Bigscreen – 10-foot interface for KDE plasma
"Plasma" is an awkward name for a television app. First image that comes to mind is the old plasma 50-inch I used to have. Damn thing weighed nearly 100 pounds and was really power-hungry.
while_true_··on Altman on AI energy: it also takes 20 years of eating food to train a human
Top philanthropists include Jamsetji Tata (donated $102.4 billion), Bill and Melinda Gates ($75.8 billion), Warren Buffett (is pledging to donate 99% of his wealth). Andrew Carnegie gave away 85% of his wealth -- including construction of over 2,500 public libraries.
while_true_··on Missouri Senate to halt all solar projects
About half of Missouri's electrical power comes from coal. The national trend is utilities ramping up on solar, wind and battery storage while relying less on coal, causing some coal plants to shut down. I wouldn't be surprised if this legislation to stop new solar is being pushed by the coal industry.
