llsf··on Water is bursting from another abandoned West Texas oil well, continuing a trend
I agree, that is a likely scenario in US and other countries.

The time horizon for those issues is not compatible with electoral terms. There is no incentive for any politician to tackle such big issue. Even though it might become existential. We would deal with the externalities until we get swallowed as it becomes unavoidable. The more we wait and the more painful it would be.

llsf··on Water is bursting from another abandoned West Texas oil well, continuing a trend
Yes, oil is a limited resource. US became recently the largest oil producer in the world (source: https://www.eia.gov/todayinenergy/detail.php?id=61545) and the additional output comes from the Permian basin only.

Texas became the 8th larger economy thanks to the increasing oil production (larger than Russia or Canada). But Texas should invest that money (like Norway or UAE does) as it won't last for ever. When oil is gone (or too expensive to extract) people will leave Texas, and Texas will be a wasteland with orphan wells everywhere polluting underground water.

In general, it would be wise for US to get an exit plan, for when oil would not be so easy to extract (yes it is more difficult now, but the oil price is still high enough). Oil price can be counter intuitive as it is the main fuel of the world economy. So, if the production declines, the price can go up, but not too much. At some point, economies would shutdown, and the demand would fall sharply. Only the countries that would be out of oil (i.e. using electricity from nuclear, solar, wind, hydro) would continue to be humming. The other countries would enter in chaos, unrest and war. Which would generate economical migrations and more chaos.

Again countries should plan for peak fossil fuel, and even if they are lucky to have some oil underground, they should plan to massively transform their economy to electricity and transition the production from fossil to more sustainable production like nuclear, solar, wind and hydro.

Energy production is national security. Each country should treat it as national security. US is lucky to have oil/gas fields, but it would not last for ever. Even ignoring the ecological impact of extracting fossil fuel, or impact on climate to burn fossil fuel, the fact that is a limited resource should force the US to move other energy production (e.g. nuclear, solar, wind, hydro) and migrate the energy consumption to electricity... if we want to soft land, when fossil fuel would get expensive (peak production, wars, etc.).
llsf··on In one of the US's hottest deserts, utilities push gas rather than solar
We are talking about 16,000 residential town in Arizona, with no heavy industry, I doubt they would need full capacity for 12hrs straight at night. But in any case, it seems appropriate to compare to the cost and maintenance of 98MWh gas peaker.
llsf··on In one of the US's hottest deserts, utilities push gas rather than solar
Putting on the side the shady tactics that the energy company used to get a gas peaker close to houses...

For context:

"Arizona households use 66 million Btu of energy per home, 26% less than the U.S. average.

The combination of lower than average site consumption of all energy, but above average electricity which is relatively expensive, results in Arizona households spending 3% less for energy than the U.S. average."

source: https://www.eia.gov/consumption/residential/reports/2009/sta...

So people in Arizona are using a lot less energy than the rest of the country, and only pay marginally less. Someone is making even more money on the energy bill.

And yes, solar is not perfect, and sometimes one needs some extra electricity on the grid (peakers). For a 16,000 household community, maybe batteries should be considered ? It is not like they have an heavy industry requiring high energy consumption 24/7. It is a small community (houses, and RV parks).

For instance, a Tesla Megapack 2 costs $1.5M and delivers 3.854 MWh so to replace the 98MWh gas peaker, we would need 25 x Megabuck 2, for a cost of $37.5M. How much the gas peaker is going to cost ? We can run the cost on maintenance too, which I suspect would also favor the battery solution.

llsf··on Show HN: Openkoda – Open–source, private, Salesforce alternative
Considering the tag line "Ready-to-use development platform that accelerates the process of building business applications and internal tools", I would think OpenKoda would compete with Retool more than Salesforce, no ?

That is the number that a friend working for SNAP told... 1 out 8 Americans is on food stamps.

Just cannot wait to see what they have been cooking :)
llsf··on Police in Austin, San Francisco skirt facial recognition ban
Okay, in that case, the victim (as sole witness) said that she recognized the defendant as the perpetuator. I am not a lawyer, but not sure if nowadays you could go to jail just because a victim (and sole witness) recognize you ? That seems rather slim evidence, and could be weaponized.
llsf··on Introducing Copilot+ PCs
I agree that it might not arrive at WWDC unless Apple was already working on it for several years...

Nonetheless, I see this Microsoft initiative as a canary in the AI coal mine. I would hope Apple would learn from it.

llsf··on Satellites will kill cell dead zones for good – and replace it with 6G
It might kill dead zones, but still it might be a solar flare away to lose all communications. Feels like we are racing in one direction, making the solution more brittle over time. Investing in under-ground/water cables could turn invaluable one day.
llsf··on Police in Austin, San Francisco skirt facial recognition ban
Wait, having a computer saying that your face matches a video does not prove that you are the person on the video. Sure, the police can talk to you, but that is not a sufficient piece of evidence.
llsf··on Introducing Copilot+ PCs
I cannot wait to see Apple's response. While Microsoft announcement seems rush and products half backed/thought, there are on to something. I would hope Apple would learn from it, and find the right path.

I would really like to have a AI companion that runs locally, on my dev laptop, tailored for my developer's needs. Something optimized for the hardware, and yet with tight privacy.

Apple... your turn!

llsf··on Zwentendorf Nuclear Power Plant: Finished in 1978 but never used
I would think Russia makes more money selling fossil fuels than by promoting nuclear energy.
llsf··on Reasons not to take Lumina's anticavity probiotic
Okay, so what happens if I (french) kiss a person that is taking this bacteria producing continuously mutacin-1140 and ethanol ? Could it take over my mouth, and I would ended up mutacin tolerant, and accelerating my cirrhosis ?
llsf··on Good, Kind, Caring People Became the Bad Guys
I was thinking of lately to the people holding power these days and their responsibility and involvements into the current state of affairs (politics, large corporations, climate/energy crisis, etc.)

I was wondering if having people over 60-70 or even 80yo running most of the things that matter in this world, was missing the radical optimism of youth.

That is why I like students protesting, even if misguided or not well expressed. It shakes the carefully assembled (and sometimes also misguided) world order we are living in.

Sometimes complex problems need to be revisited from fresh perspective, and have the "wizened nonagenarian Australian with little time left on this earth" to fuck off.

llsf··on Sound-suppressing silk can create quiet spaces
It is a floor/ceiling situation. But the floor as a nice old intricate hardwood floor, and ripping it off would be a shame. Looks like we can do the sound insulation fro the ceiling of the apartment downstairs, but

1. It requires the occupants to vacate

2. It is expensive

3. It is difficult to estimate the change it would actually provide

llsf··on Climate protesters storm Tesla gigafactory in Europe
Feels to me that it is a cry for attention. It is like pouring red paint on the Mona Lisa. It seems a bit disproportionate, but it clearly provides some publicity for those activists with little investment. The same against another random Volkswagen factory in Germany would have not the same impact and worldwide coverage. It is an efficient way to make a local town issue, becoming a worldwide cause.

Lobbied by who ? Unlikely Tesla itself as the company would have likely move the factory few kilometers away if that could guarantee future expansions.
llsf··on Wookieepedia: Wiki encyclopedia on the Star Wars universe
Maybe I missed it, but could not find much on the origin of Star Wars. I was hoping to find some deep analysis on the original work to build the saga. From early 1970's.

George Lucas created a great story with rich visuals from lots of various prior art, that I find interesting to understand (e.g. source: https://www.wired.com/2016/01/valerian-laureline-star-wars/)

llsf··on Sound-suppressing silk can create quiet spaces
I found this to be true for cars and maybe trucks, but not for motorbikes. Some extreme motorbikes rattle all parked cars and trigger alarms.

When Harley-Davidson and other moppet/scooters would be all electric, that would be quitter.

llsf··on Sound-suppressing silk can create quiet spaces
The particularly frustrating part is that is usually way cheaper to put sound barriers during construction, than retrofitting later on.

We have been discussing this with my neighbors. We are both committed to eventually pull the trigger to retrofit, but the initial estimate is $70K and one apartment being under heavy construction for months...

llsf··on GhostStripe attack haunts self-driving cars by making them ignore road signs
As long as cars are gracefully handling weird visions (like Stop sign in middle of 80mph highway) it should be fine.

When I was 1yo my dad was driving on the highway, got distracted, and ended up on a highway portion that was under construction. He was driving full speed, when he saw a barrier, late enough that he swung the steering wheel to avoid the barrier, and ended up driving on 2 wheels before the car felt back and stopped. No baby at the time, my grand-ma was holding me in the back (good old years when cars were lighter and less secure).

Random things can happen on the road, including wrong signage. As long as the car can assess the current state and graceful transition to a safe spot, it should be fine to throw at them random signage.

llsf··on When do we stop finding new music?
Sure, there is no hard limit on the length of a song, but most are limited to <5min and based on a much shorter melody, just repeating in loop. Now older than 10yo, I understand that there are additional variables that increase the number of possible melodies. Turns out lots of popular melodies only gravitate around 4 chords (https://en.wikipedia.org/wiki/The_Axis_of_Awesome)
llsf··on Can turning office towers into apartments save downtowns?
If the build ing is too wide, could we still do a mix use ? With residential on one side, and office on the other side / interior of the building ?

llsf··on Bollards: Why and What
Funny, just drove today in SF and saw and it looks like someone when straight into that house again...

https://www.google.com/maps/@37.7475584,-122.44409,3a,75y,89...

The City or the owners should put some bollards and be done with this once and for all. In the past 15 years they had some many cars crashing into their houses.

llsf··on Visiting the most expensive nuclear station
The need to electrify the economy has more to do with peak fossil fuel or level of CO2 in atmosphere, than nuclear.

Comparing nuclear and wind is a bit apples and oranges. One is intermetent and one is not. The lifespans are different too, as nuclear usually last 60 to 80 years, when wind farm is 30 years. As mentioned in the article the cost of nuclear is artificially inflated, like for redundant safety measures, and specifically in UK by the financing used (most of the cost come from interest).

We need to build cheaper and more nuclear power plants, and more wind farms too.

llsf··on Visiting the most expensive nuclear station
As everyone mentioned there is no much prospection, and we are only scratching the surface.

And this is only counting with the old nuclear power plant designs. The current Gen3 and coming Gen4 do not need nearly as much as the previous generations. They squeeze more juice out. (source: https://www.amacad.org/sites/default/files/academy/pdfs/nucl...)

We might unfortunately (because of the chaos that it will create) ran out of oil before uranium.

Fossil fuel crunch will eventually happen, and it would not be pretty, unless we electrify most of our economies (source: https://flowcharts.llnl.gov/sites/flowcharts/files/2023-10/U...) and replace all the fossil fuel based production... This is the national security issue that every country should put as a priority.

llsf··on Visiting the most expensive nuclear station
Exactly. Chernobyl is FUD. All current reactors are different design and cannot be compared to Chernobyl. Nuclear is one of the safest way to produce a large quantity of energy. There is no clean energy, harvesting and transforming energy takes materials and generates stuff that we don't want.

Talking about bad perception, fear of radioactivity is also disproportionate. It might be because it is not something we can really feel with our senses, and so it has this magic/unknown aura. People working in nuclear power plant receive less than radiologist technicians, dentists, or fly attendants. Which probably means that the safety might be too high. We should be able to drop from few notches. If coal was the agreed standard of death/TWH then nuclear could kill 800 times more per TWH. The public safety standards for coal and oil is well accepted. No one when building a multi GWH coal power plant screamed for the caused deaths. An yet, with nuclear kill 800 times less, it is always seen as something that will wipe the neighborhood. It is irrational. It might be because of the bomb of the same name. Even though they are totally different designs (nuclear power plant do not detonate large amount of explosive to start a reaction).

It is fine to be cautious, but we have to stay rational. We should not diminish the risk of radioactivity, but current nuclear power plant designs are safer, and when they fail (even when a tsunami hits it) it does not kill as many people (source: https://world-nuclear.org/information-library/safety-and-sec... https://www3.nhk.or.jp/nhkworld/en/news/backstories/2324/)

There and XKCD for everything: https://what-if.xkcd.com/29/

llsf··on Visiting the most expensive nuclear station
You are right, th link shows that nuclear is the safest right after solar, if you count dead/Terawatt-hour. 0.03 for nuclear and 0.02 for solar.

Solar is still very small (and intermittent) when it comes to production, for instance, less than 2% for US (source: https://flowcharts.llnl.gov/sites/flowcharts/files/2023-10/U...). This single new UK nuclear power plant alone would account for 7% of UK production according to the article.
