The @ Symbol in Hipchat

At KISSmetrics our team is distributed around the United States. When we interview candidates a common question asked is how do we like working remotely from one another. We love it. We use Hipchat as our water cooler, breakroom, and discussion area.

However, there is one thing in Hipchat that needs to be explained. By default, Hipchat will make a noise and bounce in your dock anytime a message is sent. This can become annoying during the work day since Hipchat is used as a water cooler and most of the stuff discussed is not mission critical. You are able to turn this functionality off, and most of us do. But this brings up the notification for the @.

The dreaded @ symbol. In Hipchat, anytime someone mentions you with an @ in front of your name the dock bounces and a sound goes off. This means that someone is attempting to bring something to your attention. There is also an @all that will ping everyone that is in the room, even if they are offline.

The way this @ symbo

Dudely beloved we have gathered here today for largely ceremonial reasons. We are here to participate in a wedding or, in the parlance of our times, to witness these two Dudes in the process of getting hitched (NOTE: Dude is the proper nomenclature for both male and female folks).

By this act we unite Nigel and Sue in dudely matrimony. Wedding are normally complex, lots of ins, lots of outs, lots of what-have-yous. What we do today is simple and is done in harmony with the laws of the state of Arizona and in the beautiful tradition of Dudes throughout history who (while not hee-ros, cause what's a hee-ro?) fit in with their time and place.

Nigel and Sue, before I lose my train of thought, I want to affirm that you stand before me having requested that I marry you both without compulsion but with joy. Do you both do this abidingly and without being uptight?

(They answer "Heck yeah, of course")

Do any of you compeers know of any new shit that's come to light concerning

I had a customer ask me about modifying index_interval. They want to increase the sampling with *-Summary.db files, so they're trying to increase from the 128 default value to 256.

But what they're experiencing is that if they ALTER TABLE after setting the value, index_interval returns to 128.

I reproduced it with C* 2.0.9:
