I read this as "Lush was in trouble due to a whistleblower" and not "Facebook sucks, so Lush quit". Even the article was unclear. I don't consume media often so this initially scared me that Lush was including toxic products until I concluded it was a Facebook whistleblower, not a Lush one.
To clarify: "Lush quits social media due to Facebook's bad impact on society"
Magnetic chargers for all my devices: https://www.aliexpress.com/item/1005002239613192.html
For context, I never transfer data through cords for my devices. I have semi-permanently affixed these chargers to my devices and now I have chargers that work for all of them. Life-changing purchase.
Cheap Earbuds: https://www.aliexpress.com/item/4000507169624.html
I bought 10x of these for ~1 USD each, and it put a pair in every bag, box and jacket I traveled with so I'd always have a set with me no matter what. Very convenient.
Sleep mask: https://www.amazon.com/dp/B07KC5DWCC
Also life-changing. I have 16 windows in my room and this allowed me to finally sleep past daybreak.
Ear protection: (not exact pair, but similar) https://www.amazon.com/12010-34dB-Highest-Safety-Muffs/dp/B0...
Combined with the aforementioned cheap earbuds, these replace 200+ USD noise cancelling headphones for ~15 USD total and allow me to concentrate at work.
Rechargeable batteries (AAA and AA), and recharger:
I use these for everything that requires batteries.
>How do the oracles work with these kinds of smart contracts?
It depends. Many exploits are based on asymmetric oracle data, or asymmetric trades using flash loans. Mainly oracles will be used for aggregated price feed data from centralized exchanges, thus making the prices an average across the board. This keeps it even for everyone involved that integrates the same oracles that everyone else does, and a proper oracle network will keep bad actors at bay by mitigating excessive arbitrage opportunities. Well-meaning oracles are critical for these kinds of decentralized finance opportunities.
>You can borrow crypto against other crypto?! What is the use case for that?
If I put my tokens up for borrowing, I'm providing liquidity into a pool. It allows me to leverage my own money into a series of "IOU's" from smart contracts that pay out dividends by collecting small fees from people who borrow from this pool as a payment for providing this utility.
To answer your second question: The use case is ultimately adding liquidity to the market, and getting paid for doing so, while also being able to leverage the IOU's (in some scenarios) into more dividends payouts.
It sounds more complicated than it is. Boiling it down looks something like this:
Provide - ETH-BTC to a pool || Receive - aETHBTC tokens (an IOU)
Provide - aETHBTC to a pool (an IOU) || Receive - aETHBTC tokens (an IOU)
Provide - yaETHBTC to a pool (an IOU) || Receive - yyaETHBTC tokens (an IOU)
... etc.
It's interesting and affords a lot of opportunities, but you should be careful to read every contract and only enter positions that have none or little "impermanent loss". I'd recommend you find the fee structure for a pool, find the market demand and study what the pros/cons are of lending your money. You may lend out a token and it may drop in value while those IOUs become worth less while you're trying to cash them out. Or, you may borrow an asset against your assets to market sell and effectively short the borrowed token, only to be liquidated when the token rises and you need to pay back your loan.
Just be careful of your gas bill while you're learning :)
Thanks a lot for the detailed answer. I'm presently not interested in using any of these services, but I am trying to keep up with the developments of crpytofinance.
I purchased 6 sets of cheap headphones so I could keep them in all my backpacks/bags/around the house. Anytime I forget to bring headphones to listen to my iPod, I know I have an extra set in my backpack.
I purchased 10 USB chargers that attach magnetically. I keep 2 at the office, 1 in my gaming console, 1 in my computer, 2 in my car, 1 in the wall with an adapter next to my bed and have the other 3 set aside. The metal connectors wear out after a year or two of constant use. I recommend getting the 360 degree ones. I also bought two 3m USB extenders so I can plug in my console peripherals from where I sit while gaming. One for now, one for later just in case. Overall cost of this was ~$60 but it's some of the best money I've ever spent. The convenience is incredible and since all the adapters are the same, they work with all my devices as long as they're not being connected for data transfer reasons.
The best thing I've ever bought that has improved my life, has been an "extra" of anything I find myself using frequently.
$ mv file.text !#:1:r.txt
evaluates to:
$ mv file.text file.txt
(colon separated)
!# means this command
1 is the position of the argument to be modified
r means strip extension
There's tons of history modifiers and a lot to be learned reading `man bash`.
