With 70$/kg that's at the upper end of typical prices for specialty coffee (though I'm not familiar with US prices specifically). No idea if they are at a level where they can compete at that price point, a single blend as main product is rather odd for a coffee roaster. At this price point you'd usually get various single origin coffees.
knowing "startups" i'm sure their vision is streaming SSH subscription as a service . They track your keystroke rate and automatically ship new batches of $2/oz coffee when you get below 90 keystrokes/min
No joke, but "startup" can often be code for, "extremely high-quality items that are subsidized by VC money". The quality doesn't last, but if you get in early, you can often buy stuff that's way nicer than it should be for the price.
I prefer Mango Languages, which I get for free through my public library. The progression feels better to me, it's not as gamified (sorry for using that word), and there is some (though not a ton of) actual lesson content in there. For example, learning Spanish, it gives some context on the different usages of "Ser" vs. "Estar" for "to be", and it includes discussion on gendered nouns. DuoLingo may have gotten to some brief lesson content at some point, but for me it was too grating to continue with and I quit before I made much progress with it.
I prefer projects maintained by single or few developers. Gogs seems to be that kind of project. Gitea is maintained by some kind of community. Other than that, I think they don't differ that much. Gitea is Gogs fork after all.
> The Author is arguing for replacing the chain with power wires, by generating power from pedaling and feeding it into the motor (with efficiency losses of 5%)
My understanding is that the efficiency loss is strictly limited to delivering electrical power back to mechanical power via motor instead of via the chain drive. The problem with this design is that it completely eliminates the ability to deliver mechanical energy directly. The rider pedaling charges the battery which then powers the motor. Going from mechanical energy to stored electrical energy is going to introduce a much greater loss in efficiency than a mere 5%. In a more standard e-bike model, when the rider pedals, my understanding is that they are delivering mechanical energy directly, bypassing the conversion to electrical energy. I may be wrong as I am not very familiar with e-bikes, but, if this is the case, the 5% figure seems highly misleading.
There's no need to go via the battery. The electrical energy from the generator is directly used by the motor, only the excess energy (if there is any) gets stored in the battery. Both generators and motors can be very efficient (and of course the conventional chain also has some losses).
They're called "SYRYN Swimbuds Flip and Waterproof MP3 Player". Just got them a few years ago as a quick, inexpensive Amazon purchase. Looks like they're a bit more expensive nowadays, but not too bad.
They work fine-- only ones I've ever had, so I have nothing to compare them to. I can confirm they've survived over 200 hours of lap swim, though.
I think these are used as botnet command and control information. The bots randomly surf the web till they find a sequence of words or numbers that match some preprogrammed checksum or signature, and use some of the numbers as instructions of what to do.
The controller's of the botnet then spam the encoded instructions on comment sections all over the web.
The "Handy Library" Android app includes an ISBN scanner and allows you to import and export collection data.
You could also check out some of the tooling and APIs around openlibrary.org. Unfortunately, I think it's basically a moribund project, but may have sufficient tools for your needs. I know they have a list feature, but I don't think ingestion is particularly easy; nor am I sure of the import/export functionality around their lists.
edit: I'd forgotten about librarything (mentioned in another comment). They have better tooling that openlibrary.
