There is an excellent documentary by Fredrik Gertten called "Push" that explores this phenomenon, definitely worth a watch if there's a screening nearby: http://www.pushthefilm.com/
I did a similar trip last year. San Francisco can be a charming city at times, I especially recommend doing a bike tour across the golden gate bridge via the golden gate park. Alcatraz was interesting to visit too.
Just beware that it is a pretty run down and dirty city. The streets downtown are full of homeless people who seem to be not all there. I've never felt as unsafe in any city as when walking in downtown SF in the evening, it's very counterintuitive if you're used to downtown areas in Europe. Also avoid public transit at night.
OLED screens suffer from burn-in due to pixels wearing out unevenly on the screen. The effect is cumulative and can't be fixed by using screensavers. I wouldn't call it "image retention".
I have an OLED TV for watching shows and movies and try to be careful to not display static elements for too long. I would never use an OLED as a PC screen for fear of burn-in.
No reason to believe that they would, I've been on multiple planes where it was possible to bring up different camera feeds of the plane on the screen in front of me. The coolest of these was filming the plane from the top of the tail wing so it almost looked like a video game feed.
It's possible to judgde the relative positions of the photographers by eye based on some of the waves directly under the lighthouse. In Eric's picture there are some distinct crests immediately below the lighthouse door. In Ron's picture the exact same crests are on a diagonal line from the door toward the lower left corner of the frame. Tracing this imaginary line "out of the picture" would lead us to Eric's position, which means that Eric is to the left of Ron.
I can really recommend getting a Sony Xperia, especially the XZ1 which I just recently bought for myself. It has an SD card slot, a 3.5mm jack, it runs Android Oreo with very little bloat and feels like stock Android. The camera is great and can do the exact same super slow mo as samsung is advertising with the S9. The fingerprint sensor and lock button are the same and perfectly placed at the side of the phone. The battery life is also really great, now when my phone is new it lasts me almost 2 days with normal use. And relatively cheap for being a flagship. It's hard to understand why Sony phones get constantly overlooked.
I tried HRM after playing a decent bit of TIS-100, and the interface was just too slow and clunky in comparison for me to keep going. One of the more brilliant aspects of TIS-100 is that you can always see the full program on the screen at all times, and part of the challenge is to refactor code by physically moving it around the screen. HRM in comparison only displays the code as a list of commands and I found it frustrating to navigate through, especially for big programs.
Another really satisfactory part of the gameplay of TIS-100 was that I sometimes came up with a new optimization to solve a later challenge, and could then go back to my old solutions and get large speedups by applying the same optimization there. It made me play the game nonlinearly and go back and forth between the challenges and trying to improve my code in them. It's just a lot of fun for programming-minded people.
You seem to be thinking of your PS4 as a "home console" and the Switch as the "portable", whereas the Switch is really both those things and none of them. You can play the same games both on the couch and on the go (unless you are hellbent on always playing two games in parallel on each console).
I think the Switch will allow for a new "non-binary" way of thinking about what's portable and what's a home game, and fit into our lives in a new way. I can't wait to start playing a game on the commute back home from work (which takes well under the 2.5h), and continue the same session on the big setup later when I arrive. I think it will allow me to spend more hours per week playing big titles compared to what I can spare today.
