Phew! Having DC5 successfully out the door, I'm happy to resume my regularly scheduled programming. I'm back, bringing you my Top5 picks off of DevCentral every week. I'll help you sort through the content pouring across the (now new and improved!) site and offer you a few things that you should definitely check out. It's good to see that the content has still been chugging away even while the team was heads down working on the new site improvements. A big thanks to the awesome community and the extended DC team folks (Lori, Pete and co.) for keeping the lights on. Now that I'm back at it, though, allow me to offer you this week's DC Top5: Network Optimization Won’t Fix Application Performance in the Cloud http://devcentral.f5.com/weblogs/macvittie/archive/2010/05/20/network-optimization-wonrsquot-fix-application-performance-in-the-cloud.aspx In her blog yesterday Lori...

DevCentral Top 5 9/24/2010

Adding to the already wicked cool selection of stuff I get to talk about on a weekly basis, we’re starting to see more and more content submissions outside of normal forums use from our user base. It’s fantastic to see folks contributing articles that share their first-hand experience using F5 gear with others. This week I get a chance to talk about two different MVP contributed Tech Tips that are both interesting as well as educational. It’s been a good week so sit down, buckle up and let’s hit the DevCentral Top 5: It’s Midnight. Do You Know Where Your Tech Support Is? http:/... (more)

What Could You Do with Your Code in 20 Lines or Less?

What could you do with your code in 20 Lines or Less? That's the question I ask (almost) every week for the devcentral community, and every week I go looking to find cool new examples that show just how flexible and powerful iRules can be without getting in over your head. Here are a few more cool iRules from the forums. This week I’ve included one of the simplest, shortest iRules to ever make the 20LoL. It just struck me as something quite useful that I’m willing to bet several people will look at and say “oh, that’s handy” despite the fact that it’s not complex or long.  Keep... (more)

RTT (Round Trip Time): Aka – Why bandwidth doesn’t matter

A great post over on ajaxian got me to thinking today.  Why is it whenever you hear people talking about speed on the internet, they use a single metric?  Whether they’re discussing the connection in the datacenter, their residential DSL, or the wireless connection via their mobile device, everyone references the bandwidth of their connection when talking about speed.  “Oh I just got a 20Mb/s connection at home, it’s blazing fast!".  That’s all well and good, and 20 Mb/s is indeed a lot of throughput for a residential connection. Unfortunately for Joe Average, about 98% of the ... (more)

What Could You Do With Your Code in 20 Lines or Less?

What could you do with your code in 20 Lines or Less? That's the question I ask (almost) every week for the devcentral community, and every week I go looking to find cool new examples that show just how flexible and powerful iRules can be without getting in over your head. Well we made it to 30 editions of the 20LoL.  Soon we’ll break 100 iRule examples that are under 21 lines of code each.  Pretty neat stuff, if you ask me.  This week is the hoolio show, it seems.  The guy is just a monster in the forums, what can I say?  I sure am glad he’s on our side.  I’ve got three example...
