Velocity 2011June 2, 2011 As we approach the fourth Velocity conference, here's a look at how the web performance and operations communities came together, what they've done to improve the web experience, and the work that lies ahead. Operations: The secret sauce revisitedBy Andrew ShaferAugust 2, 2010 No one who really understands compound interest would intentionally make frivolous purchases on a credit card. No one who really understands web operations would create infrastructure with an exponentially increasing cost of maintenance. Yet, people do both of these things. Creating Cultural Change 
By Jesse RobbinsJune 29, 2010 At Velocity 2010, John Rauser presented four funny & powerful examples of cultural change, from a campaign at his office to get people to fill the coffee pot after taking the last cup, to an award winning advertising campaign. This talk explains how to "sneak past people's mental filters" and make things happen.... On the performance of cloudsBy Alistair CrollJune 21, 2010 Bitcurrent and Webmetrics ran five cloud providers through a series of tests: a small object, a large object, a million calculations, and a 500,000-row table scan.

More on how web performance impacts revenue...
By Jesse RobbinsOctober 1, 2009 At Velocity this year Microsoft, Google and Shopzilla each presented data on how web performance directly impacts revenue. Their data showed that slow sites get fewer search queries per user, less revenue per visitor, fewer clicks, fewer searches, and lower search engine rankings. They found that in some cases even after site performance was improved users continued to interact as... Four short links: 4 September 2009
By Nat TorkingtonSeptember 3, 2009 Flood Maps -- what the world will look like when the oceans rise. Interactive, so you can dial up your preferred level of environmental horror.

Announcing: Spike Night at Velocity June 19, 2009 Guest blogger Scott Ruthfield is a Program Committee member of the O'Reilly Velocity: Web Performance & Operations Conference. Web Operations is not for the casual observer: it's for a particular kind of adrenaline junkie that's motivated by graphs and servers spinning out of control. Jumping in, on-your-feet analysis, and experience-based-experimentation are all part of solving new problems caused by unexpected user and machine behavior,... Velocity Preview - The Greatest Good for the Greatest Number at Microsoft 
By James TurnerMay 18, 2009 The psychology of engineering user experiences on the web can be difficult. How much rich content can you place up on a page before the load time drives away your visitors? Get the answer wrong, and you can end up with a ghost town; get it right and you're a star. Eric Schurman knows this well, since he is responsible for just those kind of trade-off decisions on some of Microsoft's highest traffic pages. He'll be speaking at O'Reilly's Velocity Conference in June, and he recently talked with us about how Microsoft tests different user experiences on small groups of visitors. Velocity 2009 - Big Ideas (early registration deadline)
By Jesse RobbinsMay 8, 2009 (tag cloud created from Velocity session & speaker information using wordle.net) My favorite interview question to ask candidates is: "What happens when you type www.(amazon|google|yahoo).com in your browser and press return?" While the actual process of serving and rendering a page takes seconds to complete, describing it in real detail can take an hour. A good answer spans every part... AT&T Fiber cuts remind us: Location is a Basket too!
By Jesse RobbinsApril 10, 2009 The fiber cuts affecting much of the San Francisco Bay Area this week are similar to the outages in the Middle East last year (radar post), although far more limited in scope and impact. What I said last year still holds true and is repeated below: From an operations perspective these kinds of outages are nothing new, and underscore why... Karmic Koalas Love Eucalyptus

My Web Doesn't Like Your Enterprise, at Least While it's More FunBy Jim StogdillNovember 25, 2008 The enterprise sucks, just ask the web. But will the web always be fun? Velocity 2009: Themes, ideas, and call for participation...
By Jesse RobbinsNovember 21, 2008 Last year's Velocity conference was an incredible success. We expected around 400 people and we ended up maxing out the facility with over 600. This year we're moving the conference to a bigger space and extending it to 3 days to accommodate workshops and longer sessions. Velocity 2009 will be on June 22-24th, 2009 at the Fairmont Hotel in San... Sprint blocking Cogent network traffic...
By Jesse RobbinsOctober 31, 2008 It appears that Sprint has stopped routing traffic (called "depeering") from Cogent as a result of some sort of legal dispute. Sprint customers cannot reach Cogent customers, and vice versa. The effect is similar to what would happen if Sprint were to block voice phonecalls to AT&T customers. Here's a graph that shows the outage, courtesy of Keynote : I... Amazon's new EC2 SLA
By Jesse RobbinsOctober 24, 2008 Amazon announced a new SLA for EC2, similar to the one for S3.

Hyperic CloudStatus service dashboard launches at Velocity!
By Jesse RobbinsJune 23, 2008 Javier Soltero just launched CloudStatus during his Hyperic sponsor session today at Velocity. CloudStatus is a public health dashboard for web services like Amazon's EC2/S3, and Google's App Engine. Javier called to tell me about this last week after I declared that "Service Monitoring Dashboards are mandatory". This comes right after Amazon and Google had visible outages, and couldn't have... Service Monitoring Dashboards are mandatory for production services!
By Jesse RobbinsJune 18, 2008 Google App Engine went down earlier today. GAE is still a developer preview release, and currently lacks a public monitoring dashboard. Unfortunately this means that many people either found out from their app and/or admin consoles being unavailable or from Mike Arrington's post on TechCrunch. Google has a strong Web Operations culture, and there are numerous internal monitoring tools in... Two new open source projects at Velocity
By Jesse RobbinsJune 17, 2008 At Velocity next week there will be two significant open source projects debuting. The first is the Jiffy: Open Source Performance Measurement and Instrumentation tool created by Scott Ruthfield and his team at Whitepages.com. Most tools for measuring web performance come in two flavors: Developer-installed tools (Firebug, Fiddler, etc.) that allow individuals to closely trace single sessions Third-party performance monitoring... Understanding Web Operations Culture (Part 1)
By Jesse RobbinsJune 14, 2008 “You don’t choose the moment, the moment chooses you. You only choose how prepared you are when it does.” - Fire Chief Mike Burtch Last week I came upon a truck vs. scooter accident on my way home. I could hear a woman yelling in pain from underneath the truck (a good sign!) and could see a guy in the... CloudCamp gathering after Velocity
By Jesse RobbinsJune 13, 2008 On Tuesday after Velocity closes there will be a CloudCamp gathering at Microsoft's San Francisco Office. I'll be going (unless I'm too exhausted to stand).

By Jesse RobbinsJune 10, 2008 My friend Ben Black just released TLS Report, a free (ad-supported) tool that evaluates SSL/TLS configurations across websites and assigns letter grades. In the example below, Facebook gets a D because it accepts several keys that are below 128-bits and relies on MD5: Ben explains: Cryptography is arcane and complex. Cryptography is also the basis for the various protocols that... 1 to 50 of 90 Next Stay Connected
