In your life away from IT,  the verb "to brick" is how you fill in a surface with rectangles of fired clay, and "HyperWRT Thibor" is, oh, let's say either a sport drink that smells like an old sock or a lung condition resulting from trying to suck your gut in while pulling on a pair of jeans that "should" fit. However, as a public service, I offer the IT world's definition of "to brick" and "HyperWRT Thibor" in case you've been hiding under a server rack for several years or you merely want proof in writing so you can stump the office know-it-all (who of course is not in IT or he/she would know he/she doesn't know it all and would, of course, be much humbler):

Brick: (v) To screw up an electronic device so badly that its only value is as a brick, doorstop, or expensive paperweight. “I bricked my router when I tried to mess with its firmware.”

Brick: (n) A damaged electronic device: “Our conference-room telephone is as useful as a brick.” Also refers to the size of ancient electronics: “Jerry’s portable telephone on Seinfeld reruns is a brick.”

Brick: (adj) A level of backup and recovery in messaging: “As you know, a Recovery Storage Group (RSG) in Microsoft Exchange Server 2003 lets you restore a single mailbox (brick-level restore) without having to perform an individual mailbox backup (brick-level backup).” (From the Windows IT Pro article “Best Practices for Recovery Storage Groups and Exchange Server 2003.”)

HyperWRT Thibor: (n) A firmware project started by a programmer called Avenger and continued by several other developers including one named tofu and one named Thibor, to boost the power and features of Linksys wireless routers; intriguing to many in spite of HyperWRT Thibor's rendering void the Linksys warranty.

HyperWRT Thibor: (adj) Used with “firmware” becomes the most popular search phrase at Windowsitpro.com, pulling up this widely circulated article, “Alternative Firmware for Wireless APs: Thibor.”

In that same spirit of public service, (you want to believe me, don't you?) here are some potentially useful resources and best practices to measure against your existing wireless knowledge:
