Though it might also be worth mentioning that Tumblr is a total pain in the * to use precisely because of that customization. Every dang page is different and I never know what to click. Worse, Tumblr is so slow that every wrong click is an expensive loss of time and patience. On the rare occasion that I find a Tumblr worth following, I just use the RSS feed because the site is too frustrating.
This was discussed in the book "Flashboys". The real challenge with high speed trading in the long distance communication between the stuff on Wall Street and the commodities action going on in Chicago. That long distance communication is what many of these towers are being used for.
I've been using Duolingo to learn Italian. It was awesome up until about 40% fluency, then it lost its effectiveness. It was a great way to learn basic vocabulary and sentence structure, but after that I learned more by just reading my news in Italian.

This probably does not affect android. In 5.0, android switched to AOT with a new VM, ART instead of Dalvik, which was a huge win for performance. Jitter in many, many apps went away completely, especially when scrolling. This did cause install times to increase, however. In 7.0 (or 7.1?) there is a mix of JIT with AOT for code that is deemed hot by a profiler, hopefully bringing the benefits of AOT without the lengthy install times.
Android and Oracle's Java have been diverged for quite a while. There aren't any Java 8 features available to Android now, so you sadly shouldn't hold your breath for any Java 9 features either, it will probably be a long, long time.
I came here to ask about that too. From what I've heard elsewhere, it sounds like Google is smart enough to figure out if you are posting unrelated content just for SEO purposes, and that engaging in such practices is a good way to get Google-smacked.
