  Why is my IP blocked at a website I visit regularly after I changed ISPs?

I just installed a new Express Card with Verizon Broadband wireless last night. Had tons of fun accessing the web from places I usually cannot, (we are in trucking) until I got to my favorite forum. It's a public place I have been to thousands of times, but instead of happily browsing all the daily news events and checking to see if the world blew up yet, I found myself blocked by a big white screen that said YOUR IP ADDRESS HAS BEEN BANNED.

  Fujitsu CTO: Flash is just a stopgap

Flash is a necessary waystation as we travel to a single in-memory storage architecture. That's the view from a Fujitsu chief technology officer's office. Dr Joseph Reger, CTO at Fujitsu Technology Solutions, is that office-holder, and – according to him – flash is beset with problems that will become unsolvable. He says we are seeing increases in flash density at the expense of our ability to read and write data. Each shrink in process geometry, from 3X to 2X and onto 1X, ...

Casual Talk Golang is quite enjoyable to write, aside from the tedious if err != nil checks. One of the fundamental reasons for the joy is goroutine, a core feature of Golang. Understanding goroutines in detail is worthwhile, as they contribute significantly to the pleasure of working with Golang. So, let's talk about goroutines, hoping to provide some insights to the readers.
