Excerpt from http://paper-leaf.com/alton-jquery-scroll-jacking-plugin/
"Scrolljacking basically means we replace native scrolling (what
you’re used to) with targeted scrolling: when the user initiates
a scroll, either with their mouse or keyboard, scrolljacking
takes them to an exact vertical point on the screen (for example,
the top of the next content container). When done properly,
scrolljacking can be a part of a unique, enjoyable online
experience."The above definition makes it quite clear what
scrolljacking is.

in their product pages. This is method that ‘re-wires’ the

Restating MySQL can be really annoying. You just want to disable the goddamn query cache and it takes forever (read 5-10 minutes) to shutdown, not to mention the warm-up time. Yes, with MySQL 5.7 you can do many changes online, so you won’t necessarily be restarting that often, but you still need to do upgrades, occasionally increase redo log size and, admit it, enable skip-grant-tables. Here’s how you can make this process way less painful.
Why is MySQL so slow to restart?
Before we go any further, let me tell you right away that when I’m speaking about MySQL here, I’m actually speaking about InnoDB, or rather, a MySQL server that’s running InnoDB as the main storage engine. And if that’s not your case, do not read any further. You’ve been warned!
Now.. ah yes. Restart. So, restarting MySQL involves two slow stages. I have already mentioned them, but repetition is the mother of skill, so let me say …

A few years ago, I wrote the original OmniSQL as a Perl script to automate the execution of queries across many MySQL servers and, in some cases, provide basic aggregation functionality. Shortly after that time, Justin Swanhart released Shard-Query and Domas Mituzas released pmysql, so OmniSQL was retired.
I’m a daily user of pmysql; indeed, we run a heavily patched version. Lately, I find myself needing to extend the functionality even more than we’ve already done. After a bit of evaluation, I decided that C wasn’t the best language to move forward with the new features. Thus, OmniSQL is reborn in Go. While initial testing indicates that it is an order of magnitude slower than pmysql running against 1,000+ instances of MySQL, it’s still well within my tolerance (and there are many areas of …
