From the mines to your mobile: the questionable lithium battery supply chain

“Laptops, smartphones and tablets are all powered by rechargeable batteries – and lithium-ion is the market choice. Aside from portable devices, these batteries are also crucial to the growth of the electric vehicle (EV) and energy storage industry, both key elements of the transition towards a greener economy.

The growth of these industries is fuelling a boom in global demand for several metals which make up lithium-ion batteries. This is particularly true for lithium and cobalt, two metals coveted for their unique properties. Lithium makes a battery rechargeable, whereas the high energy density of cobalt provides boosts battery power.

Global reserves for these two metals are strongly concentrated in regions with weak environmental regulations and workers rights, and where the history of natural resource extraction is one of exploitation and environmental degradation.”

100 Websites That Shaped the Internet as We Know It

” [2019] will be the 30th anniversary of Tim Berners-Lee’s first proposal to CERN outlining what he originally called the “WorldWideWeb” (one word). Since then, Berners-Lee has had a few regrets about what’s become a bit of a Frankenstein’s monster, and who knows what the future holds. [In the linked article you’ll] find [Gizmodo’s] somewhat arbitrary idea of the virtual destinations that mattered most, ranked and curated by the Gizmodo staff and illustrated with screenshots that exemplify their history, as we’ve played, shared, fought, and meme’d our way into the current millennium. ” gizmodo.com

How a Bunch of Lava Lamps Protect Us From Hackers

Remember lava lamps? turns out, they’re like tiny universes. After the bulb’s heat distributes fully throughout the lamp’s interior fluids, spherical globules in various pastel colors and sizes begin to move slowly and silently about exactly as the natural laws of physics and fluid behavior require. Smaller globules coalesce into larger ones, then disassemble and separately join with others. Some globules at the base stretch languorously upward, merging with random spheres hovering at the top, and then both reform into a single, larger sphere, and then break apart and reform yet again. Some small globules independently slide around in the fluid, occasionally bumping into one another but bouncing off and traveling on independently.

The paragraph below describes how Cloudflare uses lava lamps to generate random numbers.
“Every time you log in to any website, you’re assigned a unique identification number. It should be random, because if hackers can predict the number, they’ll impersonate you. Computers, relying as they do on human-coded patterns, can’t generate true randomness—but nobody can predict the goopy mesmeric swirlings of oil, water, and wax. Cloudflare films the lamps 24/7 and uses the ever-changing arrangement of pixels to help create a superpowered cryptographic key. “Anything that the camera captures gets incorporated into the randomness,” says Nick Sullivan, the company’s head of cryptography, and that includes visitors milling about and light streaming through the windows. (Any change in heat subtly affects the undulations of those glistening globules.)”

Swift Selection Search — Firefox Addon

I do a lot of searching on the internet, and  Swift Selection Search makes my searches easier and more enjoyable. When I select text on a webpage, SSS opens a popup nearby that gives me a choice of —

  • Copying the string,
  • Using the selected string as a link to open a webpage.
  • Searching for the selected string, either via a search engine (think Google, Bing, etc.) or via a website’s own search function (think Ebay, Amazon, NYTimes, etc.).

Swift Selection Search’s summary description simply says “Swiftly access your search engines in a popup panel when you select text in a webpage. Context menu also included!”, but that doesn’t really give a clue as to how good it is. You’ll get a better idea of SSS’s capabilities by reading the fuller description farther down the page  https://addons.mozilla.org/en-US/firefox/addon/swift-selection-search/?src=search.

SSS is customizable. You can add or remove items and rearrange the order of items. I found adding items a bit tricky until I figured out that I needed to include  the string [={searchTerms}] (without the square brackets). You can get clues for formatting your entries by closely examining the items already included in the list presented when you click “Options” in SSS’s panel in FF’s Addon Manager tab, and by looking at the format of results when you directly manually do the search you want to add into SSS. It is a learning experience, but the result is worth the effort. I’ve found that 13 items is about as many as I want to include in my SSS popup window.
