"Autocorrect is my worst enema."

When Dennis attempted to enter that code into her phone, county officials believe her device’s autocorrect feature changed the spelling of FWW to the word “FEW.”

Instead of being directed to Volusia County’s parking payment website, Dennis received a link to a similar-looking website used to collect parking payments in Detroit, Michigan.

“I don’t know that I’ve ever been to Detroit,” Dennis told News 6.

Unveiled at the American Society for Mass Spectrometry meeting in June, the system spots fentanyl vapour at six parts per trillion, far surpassing the five‑ to thirty‑minute turnaround of current swab tests. That’s sensitive enough to detect even the faintest trace of the substance.
...
A commercial version that can detect both narcotics and explosives is expected to roll out later this year.

Fossil fuel powering solar manufacturing
Much of the world’s solar gear is made on fossil power. The IEA finds that “coal generates over 60% of the electricity used for global solar PV manufacturing,” far above coal’s ~36% share of typical grids. That is because over 80% of PV factories sit in Chinese provinces like Xinjiang and Jiangsu, where coal dominates the grid.

China has poured over $50 billion into solar factories since 2011, roughly ten times Europe’s investment, cutting panel costs by about 80% and fueling a worldwide solar boom. But those panels were produced on coal.

And people wonder how, in the old days, sometimes there could be "cross talk" between two (or more) telephone lines:


You’re looking at the cross-section of a telephone cable packed with up to 3,600 color-coded copper wires. Each pair once carried a separate landline, bundled together to serve entire neighborhoods through a single trunk. Can you believe all of that fit into one cable?

I know, it should be twisted pair, but I can't see the twists in the pic ... maybe the twisting pitch is too long to be noticeable in such a short segment?
Yea, it's an audio range twist not digital UTP or RF. Good audio cables still work up to the MHz range with proper signal equalization. We had several linking the major comm stations I worked at all terminated on wire punch-down blocks.

Those floatation devices in that image are not "inner tubes".
It's was a size based regulation that they said also covered "inner tubes".

In Oregon (the only place that it matters on this) they are sold and classified as "inner tubes" per state regulations that have been 'revised' not to be enforced. The money grab law is still on the books but backfired so hard, they ran for cover.
