Laser Eye Surgery, Revisited 10 Years Later

ProfFalcon Re:A few reasons (550 comments)

Risk - Odds are everything will go fine but my eyes are pretty important to me. Is it that big of an inconvenience wearing contacts? Not for me. Been wearing them for over 25 years with no issues. If I couldn't wear contacts though, laser surgery would have been more tempting.

Risks of eye infection from contacts is very real and proven. Happens more than damage from a skilled professional performing eye surgery...

Ask Slashdot: Anti-Theft Products For the Over-Equipped Household?

ProfFalcon Re:Guns (408 comments)

Someone willing to take a life when their own life or another's life is not in danger is not the type of person who should own guns. Gun owners need to know when using lethal force is just. Saving your possessions is not a good reason to take a life.

"Loud Commercial" Legislation Proposed In US Congress

ProfFalcon Re:I'd much rather... (636 comments)

Yes, we do. We do not have to watch channels that have tactics we do not like.

Yeah, but this is a tiny thing. If you're going to stop watching a channel over this as the sole reason, then with a standard so tight you probably will end up not watching TV at all.

I like to turn on the TV in the mornings to see how the weather is going to turn out. My wife is still sleeping so I keep the volume low. I absolutely refuse to watch Kare 11 here near Minneapolis and have decided I detest Amb*** CR due to their advertisements (*** inserted to avoid improving their Google ratings with my rant about them). At 5:10am they have a commercial for their sleep aid with a rooster at extremely high volume, much higher than the rest of the news cast. I have no idea what made the advertiser think it was a good idea to have a sleep aid advertised during "quiet hours" with a very loud commercial. Asinine.

I manage a data center where we use many of the twist-lock outlets. True, you can't get them out quickly when the robots start taking over the world. Terrified me greatly. I locked all of the equipment up in racks with locking doors on the cabinets. Can't be too safe!

What Would You Want In a Large-Scale Monitoring System?

ProfFalcon Re:OpenNMS (342 comments)

I looked at many different commercial options here at work and purchased EMC Smarts. The root cause analysis is very helpful. It has saved us a lot of time tracking down some outages we've had here. It can tell you, for instance, that a specific port on a switch is down or flapping which is causing problems.

Most of the other tools we looked at would tell you that all of the servers at a remote facility was down but Smarts will take it one step further and identify the root cause so you do not spend time figuring out if one of the routers on one side or the other is down, if it is the link itself, a firewall, etc. It is all information you could tell on your own but none of the other tools even went to the detail necessary to track the problem down using only the information presented in the tool. Smarts goes even further and specifically points at the problem point.

There are a bunch of other modules you can buy to help you automatically model application/system dependencies to find out which business units are impacted by an outage, what systems/applications would be impacted by a DB outage, etc. Other modules can track application performance in all of the steps from workstation all the way through the network into each server and DB using just network monitoring or through synthetic transactions.

It is not cheap by any stretch of the imagination but implementation is fairly easy with its autodiscovery providing huge value. If you want to use it to its fullest, it will take some learning and a bit of time from a good administrator.

Before anyone asks, I was unsuccessful getting open source tools seriously considered. I had implemented OpenNMS very successfully and was using unofficially to monitor for outages and track system availability.

Doing this right is not a light task if you want all of the detail necessary to properly manage a large-scale network. We getting into the level of detail of monitoring server memory utilization, disk space utilization, CPU, switch/router port utilization, etc. It is taking at least one full-time administrator just to manage it. I wish you luck on developing a new tool. I would encourage you to look at some of the existing tools before trying to build your own. Just implementing a tool that has been around a long time is a huge process. Building and implementing....
