If you would like more info on ControlPoint, contact Warren Talbot via old fashioned email at w.talbot-at-f5-dot-com (he's not hip to the whole Skype thing yet - but don't worry, we'll get him there...).

Don is going with "Option B" this week.

This last week Joe implemented the audio transcripts on Tech Tips, wrote a tech tip on iControl Marketing dissected, a forum post on how to detect DOS attempts. Jeff is recovering from a cold and comment on our plan to increase the flood of tech tips as well as Deb's tech tip on on iRules based on External Information that caused a nice banter between "the dueling Mac Vitties". Colin wrote a tech tip on "Avoiding Path Traversal" and is in the process of encoding some video from his recent trip to the UK. Deb points to some codeshare entries regarding Caching POSTS, Pool picking based on Cipher Strength, and a Super HTTP Monitor, SQL Monitor, and DHCP Monitor, as well as a short timeout HTTP monitor. Aside from being "Mr. Negative" this week, Don wrote a tech tip on using kSOAP2 and has his app running on a Blackberry!
Next, Nigel Burmeister, a Senior Product Manager with Acopia Networks, was kind enough to sit in for the rest of the podcast answering our questions on the newest member of F5's family of products.
Acopia is primarily about File Virtualization (a logical representation of physical resources). They break the bonds between the physical file storage systems (file servers and NAS devices) and the users and applications. It's hard to allow for growth when users increase or more storage is needed. Digital content creation is one of the biggest drivers of growth requirements. According to IDC, by 2010, we will be creating 988 Exabytes (That's 988 Billion Gigabytes) of digital content a year! He then talks about Storage Tiering and how it can be used to save storage and backup costs. Jeff asks what's a "WOW" feature and Nigel points to the architecture and how what they've done can't be replicated in stock software, and Colin attests to that fact....

Joe and Colin discuss how quiet it is in the office heading into this Labor Day weekend with the rest of the team taking an extended vacation.
Colin discusses his whirlwind gallivanting trip around Europe. He met with a lot of f5 folks and customers and partners on his 2.5 week trip. He went to London/Redding/Chertsey England, Edinburgh Scottland, London England, Paris France, Helsinki Finland, London England, and back to Seattle Wa- whew... The one lesson he learned was to not talk to a cab driver in English next time. Joe is looking for any Maui customers/partners needing a good DevCentral overview. Joe thanks Colin for saving him from riding solo on this podcast.
Joe talks way too long but covers some interesting things including a couple of major customer visits (including the DevCentral Japan Team). Joe notices a uprising of iControl based solutions mainly targeted at making the network more dynamic in real-time including both LTM and GTM. He mentions an upcoming release of the iRule Editor (with Partition support!) - even Joe doesn't know all the iControl methods. He gives an overview of his iRule Ninja tech tip series. He points to some forum posts on "How to install iControl", why newbie posts are perfectly welcome, how the CACHE::priority command works, how to do a wildcard cache eviction with iControl, how to get the VPN Tray client working in Vista.
Joe talks about seeing Young Frankenstein at the Paramount in Seattle. Colin is still looking for Stevie Wonder tickets - anyone have an extra one?

The team talks about why we missed last weeks podcast.
Don talks about blackberry UI coding and going from 1024x768 to 10x10. Jeff loves his wife's iPhone (but won't get them for us...). Don discusses the $100 license fees for building Blackberry apps. Jeff wonders why google mail trys to tap into his Blackberry phone log. Don brings up recent questions regarding iControl's ConfigSync upload_file and download_file methods. Most questions resolve around chunking (which the Java Wrappers completely hide).
Deb mentions a forum post on solving some fun GTM dilemmas with GTM dependencies and GTM fallback options. She talks about her helping "beta" a new advanced F5 Architecture class that should be available to the masses in the near future. Joe compares GTM's ability to break the laws of physics with the recent announcement by some scientists that they have broken the speed of light. Deb mentions a forum post on BIG-IP persistence cookie encryption. She then gives kudos to DC user kilgore.trout for his updates to the ROUTE wiki docs and user helix90 for his additions of the SCTP docs.
Joe comments on a forum post regarding a iControl Training request. He explains why a Minimum is larger than a Mean, how we've got 64 bits stats working in VB, Management with iControl for an HA Pair, upcoming partition support in the iRule Editor, how to create a hex string from the binary value returned from the iRule md5 command, and his recent attempts at getting the team to start "twittering". Jeff highly recommends TwitterVision.
Colin is out galavanting around Europe. Look for the guy holding the "Will iRule for Food" sign on the street corners and it'll likely be him.

Colin recaps the recent Partner Conference and his upcoming trip to Europe where he'll be talking about DevCentral and iControl and he'll visit a user group while he's there. He's looking for some volunteers for a few Pub meetups while he's there.
Joe went to the Seattle Lunch 2.0 meetup last week and is off to Gnomedex this Friday/Saturday. Colin gives a solution to Justin.TV's neck stress. Joe refers to some recent forum posts on 64 bit math in VB, WSDL Versioning (and why you should use the iControl Assembly), and a recent request for a single-document iRules Reference.
Deb talks about upcoming User Groups on DevCentral (UGODs for you cool cats out there). She talks about how to optimize iRules for maintainability. She highlights the benefits of matchclass with data groups. She then talks about issue with pulling stats from SNMP.
Jeff talks about the new Questions of the Week forum. This weeks topic is "How fast have you created an iRule to solve a problem". Post your best stories! He references an article by Ty Anderson on DevX about ways developers can make sure they don't forget about the network.
Don helps the team figure out how to best use the Mute button on our headsets.
Deb then leads a discussion on a DateLine show "To Catch an i-Jacker" that she brought up in her blog. Joe provides a controversial opinion on why Apple is doing what they are doing. Joe references iFixit.com and Jeff finishes up by pointing out why Fear sells...

Jeff talks about his trip last week to the F5 partner conference in Chicago. He gives some advice to Everclear about teasing the audience. He alludes to an upcoming "Question of the Week" forum and the eminent rising of F5 User Groups and how we are going to help facilitate those groups. Joe volunteers his house for a Sammamish, WA user group.
Don mentions his blog readership is WAY up after the release of the Java Wrappers for iControl Labs project. He'll likely move on to finalize the Blackberry Java iControl app (to manipulate your BIG-IP from your BlackBerry) in the coming weeks. He said he'd be done by next week - right Don???
Joe points to the latest WebAccelerator product release and why it's so awesome. He found a new iControl watch that everyone should buy just because Timex was smart enough to call it iControl. He mentions a fix to the Custom Reporting with iRules Tech Tip. He also talks about the increase in customer/partner interest in automating GTM with iControl. He then refers to the power outage last week in San Francisco (which he misstated as Los Angeles) and how if those companies had GTM, the crisis could have been avoided. He finishes with his iRule Editor tip of the week on how to use the Editor to profile your iRule.
Jeff gives one last update on the Partner Conference Party and how certain things that happen on the road need to stay on the road...
