Top Stories by Colin Walker

Here we are, weeks after the announcement of BIG-IP v10, and the hits just keep on coming. It's been another busy, exciting week here in DevCentral-ville. There has been plenty going on to keep track of, and then some, so I'll try to distill it down a little, as always. That said, it's a shame to miss any of the great stuff that's coming out, so make sure to check the rest out for yourself. You're not here for all the content, though, just the best…well my Top5 picks, anyway. Here they are:   Dear Slashdot: You get what you pay for http://devcentral.f5.com/weblogs/macvittie/archive/2009/04/17/dear-slashdot-you-get-what-you-pay-for.aspx Starting things off with a bang, a zing, and a bullet, is Lori's great post in response to a write-up about SSL acceleration. In the original article, which is worth checking out to understand the context of this post, os3 put togethe... (more)

Twenty Lines or Less #29

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. 29 editions later and still going strong. The 20LoL is a testament to just how many different things can be done with iRules in just a few lines of code.  Just imagine the possibilities if this were the 30LoL. This week I’ve got three more examples, all from the forums. Today we’ll cover dealing with port numbe... (more)

DevCentral Top5 5/21/2010

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 b... (more)

iRules Concepts: Tcl, The How and Why

F5 uses TCL as the interpreter for iRules. Many people often ask why that is. This questions is usually followed up by an immediate, "Why not Perl?" or "Why not Java" or "Why not ?". I understand the question, and frankly I'm a Perl guy from way back myself, so when I first landed at F5 and started devouring all things iRules, I was curious about the same thing. Since then I've discussed this topic with some of F5's best, in my opinion, and have come to understand that there are many solid reasons for choosing the runtime that we use. Whe... (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)
