Was WhatsApp really that successful? I can't imagine it caught on with many young adults or older who have no trouble paying for SMS given the convenience. Is their demographic comprised of kids?
Agree and disagree. The touch screen is the most important aspect of a touchscreen device. Observable lag affects the user experience when they're moving faster than the device will allow.
It is a big deal but I don't think the majority of users are bothered because they see it as an inherent trait of a computer to lag.
the latency on android gives the phones the feeling of using a computer. the lack of latency on ios gives phones the feeling of actually manipulating things on the screen.
iOS latency is still well above what's noticable by human perception. Tack on to that all of the delays you get once you're running a newer version of iOS on older devices (which I suspect is the majority of people using Apple products) and I think it's pretty obvious that there's less of a gap in how people perceive the interaction model than you're suggesting.
I know you said you don't trust digital storage, but discs remain the best way to backup files for me. I purchased a blu-ray burner a couple years back and I've hardly made it through my first stack of discs. The blu-ray discs should easily outlast any other storage medium if they're kept in proper conditions. It comes down to your ability to keep track of them, not whether they'll go bad on you.
I tried to get tickets to the show in Mountain View, completely sold out almost immediately save for a few "accessible" seats. I considered showing up with crutches or a wheelchair.
I hope Netflix picks him up for a new season of the show. He'd get the creative freedom, they'd get another exclusive, and everyone is happy.
If you're going to write websites, stay with Rails. I'm a long time Erlang developer and even today there is no good web framework (sure, a few exists, but none of them make it as pleasant to develop websites as Rails).
If you're going to write a server application, even REST and HTTP, Erlang and Elixir is a superb choice (I would argue better than Ruby with Sinatra, for example) because of the concurrency model and the ability to handle protocols and binary data.
There are also a few nice template libraries for Erlang (for example https://github.com/mojombo/mustache.erl) so if you just need some templating and don't mind writing some glue yourself it could still be a good option.
In terms of frameworks, no, nothing competes with Rails because Rails is simply too big an ecosystem to compete with on even terms for a relatively niche language. Chicago Boss is pretty nice, with a very friendly community, though. It's worth a look.
Even more amazing was the little yellow square about the size of a surface mount resistor was highlighted as 2GB of flash. I couldn't even spot the cyan square for 512MB of ram.
I think you've gotten confused. Step 6 shows the 2GB flash taking up most of the body on the bottom side – you might need to mouse-over the correct image. The RAM takes up about half the neck.
