gibolt··on Oppo Find X7 Ultra: smartphone features the first dual periscope zooms
The inbound light is bounced horizontally in the phone in order to physically be able to reach that level of optical zoom.
gibolt··on Fewer people are buying electric cars in the US
GM produced the first modern EV, then recalled and scrapped them all. Nissan was far ahead of Tesla (on sales) with the Leaf.

Both could have easily won the race if they had tried, with the massive financial instruments they had availability, compared to tiny Tesla. Instead, they kept them as compliance cars because they 'had' to and continued to push for larger gas guzzling models with more profit.

keyCode is deprecated. 'key' would be optimal and more readable :D

gibolt··on GM's big bet on driverless cars turns sour
The closest house to these stations is ~10 minute walk. There are massive parking garages, but basically no accommodations for bikes (paths upon arrival or parking). All ugly concrete slabs with no covering from the sun or elements (outside the station, for connecting transit).

Traffic is mostly caused by bad drivers. Eliminate those, raise speed limits for robocars, and lanes can be narrowed/removed.

It could drastically change so many aspects. The cost of transport could drop 10x or more (accounting for efficiency gains and longevity of EVs).

- Car ownership could end up eliminated except for those who really need dedicated work vehicles. - Goods and delivery costs plummet. - Cross-state/country trips eliminate short/medium haul flights (wake up at your destination). - People get thousands of hours back from commuting (in theory).

So many other knock-on effects similar to how smart phones changed every aspect of our lives.

I think you underestimate Aliexpress, Wish, Temu, ...

The sheer quantity of goods being shipped in, one-by-one on a daily basis make it impossible to block in any effective manner.

gibolt··on Adding crushed rock to farmland pulls carbon out of the air
Not true. True green technologies are already profit drivers. EVs, solar, wind, heat pumps... are becoming so cheap and efficient that not switching for industrial use (and often personal) costs more.

The screens are much closer to the eyes. Perceived angles may be higher than actual.
gibolt··on Speeding up the JavaScript ecosystem – Polyfills gone rogue
Is there not a config for minimum supported JS version? That would appease everyone, while maintaining backwards compatibility.

Docs should show the recommended version (modern) and show what options are available to go deeper.

Obviously adding those settings for every pollyfill in non-trivial, but burdening everyone with every pollyfill ever is also suboptimal. If anything, this would make cleanup easier going forward since it would all be classified

gibolt··on Cisco Acquires Splunk
Sounds like a double whammy. Misconfigure one AWS service, and you get hit with a giant bill from both.
gibolt··on Paint on Windows is getting layers and transparency support
Yeah, Mac solved this so elegantly.

Windows really needs a simple default hotkey to do a partial screen capture quickly, and save it to a reasonable directory.

gibolt··on iPhone 15 and iPhone 15 Plus
The battery inside your headphones is negligible. Each (for Airpod Pro) is ~1% of your phone's battery. The case has a little over 10%, if charged from 0-100%
gibolt··on iPhone 15 and iPhone 15 Plus
I had an Android phone from Motorola (that cost $10) that could be fully submerged. The seal mechanism was bulky and the phone was hot garbage.

For me, battery life for days in airplane mode is good enough if it means never worrying about liquid

Have you had any follow-up advice or epiphanies that could have reasonably helped save it, after the time of this post?

gibolt··on Sucking carbon dioxide out of the sky is moving from science fiction to reality
While this is true, we eventually need to go net negative. There is no other option.

Energy curtailment (overproduction) will likely be a common reality in some seasons by 2030 and definitely in the following decade.

Building plants that are the most efficient at using that otherwise wasted energy to 'fix' our past mistakes (plus desalination and other uses) are better than just wasting the energy completely.

gibolt··on Lithium discovery in US volcano could be biggest deposit ever found
As the value goes up, companies that sort trash and recycling will be incentivized to separate the electronics, and claim the value as an extra revenue stream.

Unfortunately, physics says battery-powered cars have won.

Using solar to power a process to make a fuel before burning a fuel that at best (way less in reality) uses 2x more energy than just powering an electric motor directly is not sensical.

gibolt··on Lithium discovery in US volcano could be biggest deposit ever found
Electric cars are better. Less moving parts/maintenance, quicker, 3x as efficient, can be charged nearly anywhere with existing infrastructure and no ongoing supply chain requirement (fuel delivery).

Energy density is steadily increasing. Hydrogen will be a short-term solution for medium/long haul flights, but will eventually be replaced by batteries.

While the 5% number may be presently accurate, it is mainly for tiny Lithium batteries. Those from vehicles are of very large + high value, and will likely end up well above 95% recycling rate whenever it is time for them to be scrapped.

This also ignores the large number of those batteries that will be re-used in grid storage after being removed from a car, and eventually recycled.

Oil is 100% non-renewable. A single, relatively efficient ICE vehicle will use over 45,000 lbs of gasoline over its lifetime (excluding all the oil to extract, refine, and transport that gasoline).

The entire oil supply chain has no chance of ever becoming sustainable.

gibolt··on Lithium discovery in US volcano could be biggest deposit ever found
Exactly. Batteries are being recycled at scale today with 98-95% material recovery rates, depending on the company.

We are still early in the development cycle of recycling technology, which means we'll be closer to 99.x% in a decade when the first large wave of EV batteries (from the last decade) could start getting close to End of Life.

Animals consume them. We consume animals. They re-enter the cycle and repeat.

They are made of fossil fuels, while alternative netting are not.

gibolt··on I cycled to all the villages in alphabetical order
The Citymapper app has been awesome to find routes through my city that I never would have found. It made biking as a car replacement far easier and significantly more fun.

Note that for really long rides, it is best to map segments of it in chunks to avoid main roads.

gibolt··on New calcium material functions as an ammonia synthesis catalyst
We produce a lot of it, *and* it has high CO2 emissions. The chemical reaction that gives concrete strength releases CO2.
gibolt··on The US government is taking a step toward space-based nuclear propulsion
There have only been 5 instances resulting in 19 fatalities. None were when exiting the atmosphere. 2 were the flawed Space Shuttle on return. Only one other was a flight system, on an experimental craft.

https://en.m.wikipedia.org/wiki/List_of_spaceflight-related_....

Today's rockets are far more reliable, and anything holding nuclear fuel should be the best of the best.

gibolt··on The US government is taking a step toward space-based nuclear propulsion
The nuclear payload could be treated similar to humans, with eject systems and soft landing built in.

The fuel will only be needed for a lighter craft in deep space. Getting it up with a high reliability rocket (like Falcon 9) significantly decreases risk.

gibolt··on The US government is taking a step toward space-based nuclear propulsion
Falcon 9 has had more than 200 consecutive successful flights in a row. That is more than double the next most successful, Delta II with 100 in a row.

It also has well over 100 successful landings in a row, while the next closest rocket has 0. (Rocket, not capsule or shuttle, which are all still far lower)
