Browsers performance and benchmark
Here I am, reading this post> Safari 4 Beta vs Firefox 3.1 Beta. Another benchmark that does not (as pointed out) represent real life. Real life browsing experience is impossible to reproduce, and I did not find a good benchmark that got nearly close to it.
I don’t really care if a single page opens 200ms faster in safari or chrome. What I and my wife really care is how the browser behave after few hours of browsing. How it handles many many opened tabs.
As my wife business has nothing to do with TI, we have a completely different experience about browsing.
I usually browse TI and games oriented site. Few ads, few flash… My wife mainly browse sites that overuse Flash and that are full of Ads…
It is common for me to have over 30 opened tabs, things that I want to read later, things that I am currently reading, and “sticky” tabs like gmail, google-reader, Rails api, etc… Depending of the browser and the opened sites, I end up with my browser consuming 200-400MB and using 5-30% of my Dual Core cpu…
My wife usually have the same number of tabs opened, but her experience is quite different, she ends ups with her browser using up to 1GB, and rarely less than 400MB. She mainly use firefox, and even if there were great improvements in the 3.x version, closing tabs does not free all the memory, she need to restart the browser once in a while (that will open all the tabs that was opened before and go back eating up memory and cpu). Of course the browser frequently gets to his limit point and become unresponsive, only restarting it fixes it.
This was completely off-topic, sorry about that! ;-)
Rails Survey
Very interresting survey about Rails about hosting, user experience, deployment, SCM, performance/exception monitoring…
That shows a little more about the current state of Rails.
Learning Ruby
There is a free and fun way to learn ruby: Why’s (poignant) Guide to Ruby
The book is full of humour and it makes it really easy and entertaining to read without losing the main goal of the book: learning ruby.
Although it is simple to read, on should have really good knowledge and understanding of OOP.
Js DataGrid
That’s especially rails related, but I’ve been looking for a good DataGrid (spreadsheet) js API and there is the best I’ve seen so far:
Nitobi has others JS API: tree, calendar… but I did not have time to look at them all.
