Acid 3 revisted

Posted in Technicalon Sep 8, 2008

In March I ran the Acid 3 web browser stress test against all the most modern browsers at the time to see how they performed. Since then, there are new versions of browsers which justify a re-run of the tests. Here are the results:

  • Mozilla Firefox 3.0.1 – 71/100
  • Google Chrome 0.2.149.29 – 79.100
  • Opera 9.52 – 83/100
  • Windows Internet Explorer 7.0.5730.13 – Too bad to tell. Perhaps 5/100?
  • Apple’s Safari 3.1.2 (525.21) – 75/100
  • Flock 1.2.5 – 53/100

All the web browsers were run on the same Windows XP system.

Then, out of curiosity, I decided to check the memory usage of each browser and found the following:

  • Mozilla Firefox 3.0.1 – 55M (After all add-ons were turned off)
  • Google Chrome 0.2.149.29 – 41M
  • Opera 9.52 – 27M (But then crashed on subsequent loads)
  • Windows Internet Explorer 7.0.5730.13 – 41M (But still couldn’t render the test at all)
  • Apple’s Safari 3.1.2 (525.21) – 41M
  • Flock 1.2.5 – 54M

New scoring system for gymnastics

Posted in Sportson Aug 6, 2008

If you watch the Olympics gymnastics this year, you may be confused by the new scoring system which will let athletes score 14, 17, or even higher. The new rules are “heavy on math” and employ two panels of judges: one for technical difficulty, which adds points up from a score of zero; the other for execution and technique, which starts at 10.0 and subtracts for errors. The two numbers are then combined for the final score. As one judge put it, “The system rewards difficulty. But the mistakes are also more costly.” The new rules were adopted after South Korea protested a scoring at the 2004 Olympics.

Acid3 Test

Posted in Technicalon Mar 5, 2008

The Acid tests are various tests for web browsers to see how well they can adhere to standards. If a web browser was a computer science project, these would the tests the teaching assistant would run on your project to see how well you did and to assign you a score.

The Acid3 test was recently released, and I ran it on a few web browsers I had installed here. Here is how they performed:

  • Firefox 2.0.0.12 on Windows: 49/100
  • Safari 3.0.4 on Windows: 38/100
  • Opera 9.26 on Windows: 46/100
  • Internet Explorer 7.0.5730.13: 12? (It was so screwed up I couldn’t hardly see the score)
  • Flock 1.1 (based on Firefox) on Windows: 52/100
  • Firefox 1.5.0.12 on Linux: 50/100

I also ran it against Konquerer on Linux, but it kept crashing. Other people are reporting other various scores with various versions.

Update March 7. I’m a little confused about how the tests work. For example, I’ve run it multiple times on the Flock browser, but I’ve seen three different scores come out. I’m confused how the same test can yield different results at different browsers on the same browser. I want things to be more deterministic.

Update March 25. I ran the tests against the new Safari 3.1 on windows, and it scored an impressive 75/100.

Update March 26. Firefox 2.0.0.13 on Windows scored for me today a 53/100.
