Unlike Blackberry, IBM’s looks more advertising thsn Blackberry so they can share a blog post with others. I’m not writing a commerical. The performance part later in this blog post was great. Also blogged about payments in here (didn’t make title because I didn’t think i would be back in time for this session). I will write more about the keynotes in the afternoon.
IBMs application transformation, modernization and revitalization to a web 2.0 experience
- Problem: what to do about the mainframe
- Solution: pay IBM. Sounds somewhat magical.
- I was expecting more because the last time I saw an IBM session at this event, it was about social networking and showed how Connections was used at IBM. It was a commercial, but didn’t feel like one.
- Did demo of turning a green screen app into a web and mobile version. Cool that the screen was originally copyright before i was born. Also thinking back to when the public library card catalog was a green screen; didn’t know what a terminal was then.
- Concept interesting – using rules and transformations to call mulitple mainframe screens. Of course, the mainframe still exists this lets use it thru web.
- However, not clear on what this has todo with web 2.0. An IBMer said javascript sorting is a web 2.0 feature. Not by my definition.
Why you have less than a second to deliver exceptional performance – dynatrace/compuware
- Book: “Designing and Engineering Time” – how people perceive time
- Book: high performance web sites
- Book: high performance javascript
- Instantaneous less than .2 second – like clicking button/pull down
- Immediate less thsn 1 second – like scrolling or paging. Because think info is already there
- Continuous less than 4 seconds – like when asking a person a question because think time. We expect request to system to take time as well. 2 seconds for something simple like home page. 4 seconds for query
Interesting
- Can stay focused on a task 7-10 seconds. By then our attention moves to something else like e-mail. Shouldn’t take 7 seconds but an upper bound. 7 seconds was early recommendation as upper bound and we got used to it training or patience to that time.
- In last three years, people got 50% less happy woth 4 second response time
- We cannot perceive a 20% time difference so need oess than 1.6 seconds to be perceived as being exceptionally fast. And that time inckudes network, dns lookup, rendering, etc
- Even if bandwidth high, high latency (travel time) still affects perceived performance. Broadband is 300ms latency. A lot when shooting for 1600 ms end to end.
- 200 kb at 1.5 Mb/s takes a second
- Client rendering typically takes .3 seconds.
- Firefox and chrome render much faster than ie or safari 4 (safari 5 only slighly higher)
- Speedoftheweb.org – compare your site to ohers
From Intent to expression @bsaren from Litle on payments
- He had a slide on Occupy Wall Street. Nice to see the slides are current. The point being things are changing in finance.
- Lines bluring between consumer and professional services like vimeo.
- Bitcoin is virtual currency. People are hording it like it is gold. [sounds familiar; I think I read about this in the paper]
- Privacy discussion needs to happen. Thinks will be differentiator going forward. [profiling by my type of credit card feels weird]
- payments intelligence – recurring payments vs person with prepaid card with money for one month
- it was interesting but more business side than tech side so didn’t capture much content
Secret Sauce from Yottaa
- Now that everyone has a website, user experience becomes the differentiator including performance
- SEO – skow sights rank lower on google=
- Impressive stats on financial impact of just one second slower load time
- Facebook and twitter widgets make site slower
- Client/browser side often adds more time than content delivery
And now on to the day 1 keynotes
