Some remarkable related stuff include:

Afonso Costa and I are working on some nice stuff embedding all the above for maemo ... so I'd say to keep tuned ..

Benchmark (stress test)

To perform the tests, it was indexed a 16Mb textual base set (by using CLucene itself) resulting in a 18Mb index ready to use.

In the patched CLucene demo, there are 850 words to be used to query the indexed base against each of them programatically, and measure the time taken by complete the batch, as well as reliability, leakage and CPU and RAM memory usage of CLucene during this stress test.

Results: (from a N810 device w/ chinook)

Although CLucene has been shown itseft as a promising option and others (i.e. the mozilla-based browser Flock) have successfully embedded it as a content search engine, it is pretty much early to say something more concrete as a conclusion about CLucene. A next round of tests will be performed soon these days, including a measure of how fast it updates its index on-the-go, as well as how good its concurrency handling is, and all it running over a bigger indexed content.

Please comment if any idea comes.

• In the beginning of 2008, I joined the Master Degree program, at UFAM and I am excited to be working with Information Retrieval and a bunch of other cool TechWeb stuff. It is supposed to finished by of the year.
  

• I could not do as much as I would like to help on some cool other open source projects, including Microb, Fennec and Prism, although whenever I got a overdose of coffee and can not get to sleep, I try to send some patches.

1. On the desktop, setup an adhoc connection manually using the pc's wlan interface (eth1).
2. And enable ip_forward in order make it to bridge to the wired network interface (eth0).

For (1) and (2) I use to use the following bash script (to be ran as root):

HOW

Smartfind ranks how similar each word in the page (yeah, that might take time depending on the webpage ... heuristics exists to speed it up, but new ones are welcome) is to the given word (input by the user). For such, we are implementing the levenshtein distance metric. The "how similar" can be trigged by the user through the Edit->SmartFind menu, to be more or less restrictive.

Well, in practical terms, whenever Firefox' original find method does not find something, SmartFind takes place and hitting a aditional "enter" fires its actition ...

If it is still not clear, see sshots bellow:

Bosses are only pleased when they get numbers and charts in reports on top of their tables. At this round, we (André, Diego, Fernanda and I) had to benchmark Mozilla and Gtk-Webkit on arm, and so we did ... Text below is an informal summary of the official report.

The page load test focuses on measuring the absolute and relative time needed by each browser to open a given set of locally stored webpages. The test is driven by a JavaScript script that fires the load of each page in the test set. Both the time speed for each Web page to load (relative time) and the total time taken by loading the whole set (absolute time) are measured. The test set is formed by 37 real-world webpages fetched using the httrack crawler and is accessible over an Ad-hoc wi-fi network via the Apache Web server.

The goal of this test is to evaluate how well browsers manage system memory during the page load test (above): virtual and physical memory allocated by each browser were monitored and printed out in a comparing chart. As such, a Bash script was developed to "watch" system memory and CPU numbers. It is basically a timer used to poll at every 1 second the browser's virtual and physical memory values from "/proc", and CPU usage from "top" (in batch mode).

Both browsers were ran against Dromaeo and SunSpider Javascript test suites and memory consumption during these tests was measure (same way as in 2).

As there is no such general browser benchmark suite (is this even possible ?), we just developed your own tools (bash and JS) for those item above that do not have renowned public benchmarks available (pageload and resource consumption).

ps: I tried Mozilla's Talos suite, which seems fine to test Mozilla but it is not portable for other browsers.

Memory consumption while doing page load test in 1).

CPU load while doing page load test in 1).

Some not accomplished things after the event:

Although the TODO list is still big, the DONE list is accomplished so that it worth making "Prism to Maemo" project public.

1) Installation

While I am still having trouble to get my upload account to 'Maemo Extras" repository working fine, I've set up one living under my personal web dir: .install file here.

Could that interest users of mobile devices ?

Not sure about the answer, but I put some effort on that these days to answer this question with some practical stuff. First, I got blassey's xulrunner armel build for maemo, checked out prism source from svn, pulled Firefox 3 pre beta 5 source base (to work as my mozilla build system), built them all together and after some hacks I got Prism running on maemo OS 2008 w/ some webapps (meebo and gmail for instance).

PS: Prism has nothing to do with web application development, it's simply providing a more desktop-application-like interface for web applications. Mozilla claims: "Unlike Adobe AIR and Microsoft Silverlight, we're not building a proprietary platform to replace the web ... Prism isn't a new platform, it's simply the web platform integrated into the desktop experience. Web developers don't have to target it separately, because".

UPDATE: Greetings to MFinkle and other for all work on this.

UPDATE2: Here is Prism as a Firefox 3 addon.
