Any Given Thursday – Digging into Nasdaq’s 3-Hour Outage

This has been an uncharacteristically bad week for web performance, with several major and historically reliable services reporting outages due to "network issues". In my (not always so humble) opinion:

"Insufficient available bandwidth causing an outage, however, bothers me. A lot. There is absolutely no good reason for insufficient bandwidth to cause an outage. Maybe a slowdown, but if a flood of network traffic (not a flood of traffic to your site, just a whole bunch of traffic on the same network as your site) leads to an outage, something is wrong, at least in my book."

Lessons from NEXT2012 in Romania

I often see folks blogging about what they learned, were inspired by, or impressed them about attending an event. it is far less often when I see a headliner, or promoted presenter blog about the lessons they learned or what inspired or impressed them after the event. I've often wondered why that is.

For me, it has a lot to do with needing to quickly shift gears upon completing an event to catch-up on all the things that I put off to prepare for the event, figure out what immediate stuff landed in my inbox while I was ignoring it, and to follow-up on leads, lessons, inspirations and curiosities from the event itself.

Well, I'm going to make a concerted effort to do better about posting my lessons from events, starting with NEXT2012, hosted by SoftVision, held in Cluj-Napoca, Romania, Oct. 26-27
So, what were my take-aways from NEXT2012?

• I'm *really* excited about how I'm now organizing and packaging my performance-related materials (more on that in a separate post).
• SoftVision did a fantastic job organizing and handling logistics.
• I am seriously impressed with the people I interacted with on both a professional and technical level.
• Those same people are social, collaborative, friendly and are able to enjoy their work and create enjoyable work environments while being professionally and technically impressive.
• Romania (as well as several surrounding areas not widely considered "software/technical powerhouses") is an emerging market worth watching.

Let's Test Raises the Bar for CONFERences

If you follow me regularly, you know that I speak at, participate in, help to organize, facilitate, sponsor, etc. a *lot* of conferences, you know I do my best to give praise where praise is due -- and Let's Test 2012, Stockholm Sweden, held May 7-9 is due plenty of praise for raising the bar for Testing CONFERences.

Lest I offend anyone inadvertently or unnecessarily, allow me to share with you how I categorize conferences.

1. Academic Conference: Summary presentations of detailed papers... frequently research based, infrequently directly applicable to industry. Papers are vetted in detail and peer reviewed (theoretically leading to high quality content, but that is a debatable matter of opinion)
2. Peer Conference: A 20ish participant, invitation only, pay your own expenses and no one turns a profit, intense 2-3day, tightly themed, facilitated, deep exploration of participants 1st hand experiences related to the theme.
3. Vendor Conference: I broadly think of this as any conference put on by a for-profit organization for the purpose of earning money, winning new clients, and/or keeping existing clients happy. I make no distinction between vendors of tools, services, training, or publications. This is what most people think of when they hear "conference"
4. CONFERence: A hybrid of Peer and Vendor conferences, focused on content and community, organized by non-profit or volunteer groups with no established financial goal beyond "break-even" designed specifically to encourage attendees to CONFER (i.e. self-manage discussions and interactions related to, extending, and/or debating presented materials, as well as simply taking the opportunity to get to network and build relationships w/in their professional community.

Personally, I find it somewhere between difficult and pointless to compare or contrast "goodness" of one category of conference with another. Each category has a purpose, a value proposition, representative instances of "good" and "not-so-good", and I've had both positive and negative experiences with conferences in each category. So do me a favor, and don't misquote this post as making "cross-category comparisons". Cool? Cool.

Now, back to our regularly scheduled blog post.



Ladies & Gentlemen, this CONFERence ROCKED! I simply can't say enough good things about it from beginning to end, but let me try to give you a summary of what's got me amped & making the "bar-raising claim":
