DevCentral Top5 01/09/2009
Welcome to the first DCTop5 of 2009! It's a new year and that means you survived the holidays, the in-laws, the traffic jams, the elections, and if you live in Seattle, record breaking snow-storms. Congratulations, it's time to do it all over. There's been so much great stuff going on in DevCentral Land in the past 12 months that it's been hard for even me to keep up at times. So when I tell you that there's even more to come, and that we're turning up the dial further still this year, believe me when I say that it's going to be staggering. We've got a killer new team-member, an invigorated crew, and an endless sea of bits and bytes to conquer ahead of us. I'm excited. You should be excited. It's a whole new year, and it's all happening...trust me.
Rest assured, dear reader, that you have nothing to fear. The DC Top5 will again serve as your faithful guide to the land of DevCentral awesomeness in the coming year, just as it was in the previous one. That said, the first step in this year's Top5 journey is to pick out what's been going on the past week (okay two weeks) that you definitely need to see. As usual I've picked my favorite gems to pass along, so here's hoping that you like them as much as I do. I give you the year's inaugural Top5:
Investigate the LTM TCP Profile: Delayed & Selective Acknowledgements
https://devcentral.f5.com/s/articles/investigating-the-ltm-tcp-profile-acknowledgementsIn his no-nonsense, down and dirty technical series detailing the different LTM TCP Profile options the LTM offers, Jason continues by looking into D-SACK, ACK on Push and more. This series is absolutely fantastic if you want to really dig into what you can and can't do with your TCP profile, why you might want to, and what you can expect by fiddling with those bits you were curious about. Whether you're a network architect looking to optimize things or you're just curious about what can be done, this one's definitely worth a read. The geek content is even relatively high, which makes me feel right at home. That shouldn't stop any of you semi or non-geeks, though, Jason's articles are definitely approachable by all, while deep enough to satisfy the inner propeller-head in all of us.
Introducing PoshTweet - The PowerShell Twitter Script Library
https://devcentral.f5.com/s/articles/introducing-poshtweet-the-powershell-twitter-script-library
If you aren't convinced by now that Joe is a force to be reckoned with in the PowerShell world, let me attempt to convince you once more. While we all know he's a guru of iControl, Joe continues to display his PowerShell foo in this awesome example of using PowerShell as a twitter client in response to Jeffrey Snover's boarding of the Twitter train. This isn't just a display of Joe's skills, though. This is a darn cool example of PowerShell and some of the cool things that you can do with APIs, social media, and a little ingenuity (and apparently free time while snowed-in over the holidays).
20 Lines or Less #19
https://devcentral.f5.com/s/articles/20-lines-or-less-19
Continuing with my quest for killer iRules that fit in the palm of your hand, 20 Lines or Less rolls on. This edition brings a couple of very cool iRules including one email submission for which I'm quite grateful. More are always welcome (hint, hint). After battling with a slight moral dilemma I even decided to post the example of WAN simulation via iRule, along with the appropriate warning that it's NOT meant for production. It's a CPU killer and a delay inducer but then again, that's kind of the point of something written to...inject artificial delays, isn't it? It also happens to be a darn cool example of iRules and what they can do, even if it's not the original intent of the language. Take a look and handle with care.
Phew, we made it! That's one down for 2009, and many more to come. Thanks, as always, for reading and please don't hesitate to submit/send in any feedback or suggestions you might have.
