Nominate Git(hub) for the Nobel Peace Prize

December 7th, 2011

Git is a decentralized or distributed revision control system. This means every programmers work together in a team, localized, but every team-member  owns the complete code, it’s back-upped everywhere, not just on one place. Git has increased the speed and ease of development for open source projects enormously. Every one can contribute and pull requests are faster issued than writing an email.

Github is a website that hosts software development projects that are maintained with the Git version system. Github is free for open source projects and offers commercial plans for proprietary projects.

Working together on software with people from all over the world, thereby spreading creativity and collecting global cooperation is the best way to achieve fraternity between people, because there is no sense in raising standing armies and go to war, when we all want to achieve a common goal. A better working… , whatever.

The decentralized aspect of Git is thus very important. Leaders raise armies and make war. People want war because they’re influenced by leaders spreading the words of nationalism and patriotic or religious superiority.

People working with people all over the world know this is nonsense, we’re all different, but have an interest in the same goal. The minds of people are versatile, that makes working with Git(hub) such a fertile soil.

Hereby Webonomic nominates Git(hub) for the Nobel Peace Prize.

History pushState issues

December 6th, 2011

Opera 11.60 broke navigation on our main website. It does not longer because I added a workaround.

It’s all related to setting the baseURI (wrongly) after ajax loading and history.pushState

To see the problem:

Open this page in Opera 11.60:

  1. http://www.webonomic.nl
  2. Click internet
  3. Inspect any element and readout the baseURI property, it’s set to

http://www.webonomic.nl/webdesign/internet

While Opera 11.52, Firefox and Chromium set it to

http://www.webonomic.nl/

according to the base href element of original the document.

I looked up the specs:

http://www.w3.org/TR/html5/webappapis.html#script-s-base-url

A base URL

A URL, set when the script is created, used to resolve relative URLs. If the base URL is set from another source, e.g. a document base URL, then the script’s base URL must follow the source, so that if the source’s changes, so does the script’s.

I’m not sure if a pushState is changing the source, I can imagine it does, so Opera’s 11.6 behaviour does make sense somewhere. On the other hand it doesn’t change the source of the script?

A couple of questions raise:

  • Is Opera’s 11.60/12.00 new behaviour a bug?
  • How do we set the base url of a json document?
  • How do I set the base URL for a script?

To me Opera 11.5, Firefox, and Chromium’s behaviour does make sense by keeping the base URI of elements to the href attribute of the base element after a pushState event.

Can anyone shed some light?

(I decided to ask this question on the Opera Dev forum as well )

The beauty of WebGL

 July 1st, 2011

We have seen some demo’s with fishtanks and aquariums, but I found a much more elegant showcase here. It stresses the beauty of infinity and brings focus to the relationship between simplicity and complexity, often found in nature.

An intriguing animated M.S. Escher drawing.

You can see the working example here:

Browser performance and CPU load

{}
 June 14th, 2011

Chromium is using 2 cores and Opera isn’t running full speed on Sunspider JS benchmark. That is the outcome of a simple test running TOP while taking the sunspider benchmark on a quadcore (AMD 630) Ubuntu 64 machine with the three main browsers: Chromium, Firefox and Opera. Opera 11.11 is surprisingly never using more then 80% CPU while Firefox 4 is using 100% and Chromium 12 150%. A quadcore can take 400%, when all 4 CPU cycles are fully utilized. Opera is the slowest performer on the benchmark, no surprise and Firefox is somehow disabling graphical output: nearly no load on X-server, and no visual graphical output, while Opera and in a lesser extent Chromium show a lot of flickering and flashing. Opera is also putting a bigger load on Compiz, the compositing window manager for Linux, AKA 3d eye candy. But Opera, as said before, is also giving more visual feedback about downloading files and stuff with an animated icon in the addressbar.

Sunspider benchmark results

Firefox 4:	Total:		   355.6ms +/- 2.6%
Chromium 12:  Total:		   348.2ms +/- 4.9%
Opera 11.11:  Total:		   413.2ms +/- 3.3%

Conclusion

Seems that Opera isn’t going full throttle on benchmarks. I wonder why that is. Chromium is the only browser that is using multiple cores, but it isn’t actually much faster than Firefox. Another interesting thing is that Chromium feels the snappier browser but actually is stressing your PC more.
