Public testing of new website release31 May 2009
The new website release is now in public testing phase! Please read the forum post carefully if you are interested in testing. You can post suggestions and bug reports in that same topic. Thank you!

I will use the test period to document the changes and will write again before the site goes live, to cover these changes in detail. I have a lot more to talk about, what this "refactored" version was all about, how will future releases work, etc which I will do over the course of the test period. Stay tuned!

Drive-By Download and Adobe Software Exploits21 May 2009
I am now almost certain that the website was victim of a malware/trojan exploit (cf. recent news) because I had an old version of Adobe Reader installed, and not because of lack of Windows Updates or carelessness with downloads and such.

The irony is, I'm not even using Adobe Reader, I'm using FoxitReader ever since versions 8 and 9 of Adobe Reader became so slow and bloated. But having not heard before of all the vulnerability problems with Adobe software, I still had the old version 7 lying around.

For Greasemonkey scripts users17 May 2009
The website recovery yesterday has affected a couple scripts from our extremely prolific author woelpad! (apologies, as I had to restore the site from a copy that had small differences in the code).

Please check the Woelpad's scripts topic for the updated scripts (as of writing woelpad has updated "Alter Sequence", and "Substitute Keywords"). Also see RevTK Lite.
About the long downtime Fri & Sat16 May 2009
On Thursday May 14, approx 5pm US time, the website fell victim to a very recent malware exploit dubbed "Grumblar.cn" (also identified as "Js:Redirector" by the aVast antivirus software).

Reviewing the Kanji was in good company with much bigger sites like Variety.com and Tennis.com among the victims... though that is little consolation.

So how did it happen ?

Read on for the gory story, and some instructions for Windows users who would have visited the site yesterday, and who may have been exposed to the malware.

Scalable Vector Goodness4 May 2009
Development of the website is ongoing, and the refactoring of the existing website pages/features is almost complete.

Last week I have converted the Leitner bar chart to SVG (VML on Internet Explorer), with the excellent Raphaeljs javascript library. I was surprised to find that the graphics can work flawlessy in all major browsers: Safari, Opera, IE, Firefox, Chrome! This is very exciting because it means I don't need to use Google Charts, or FLASH, or complicated image/css tricks to do graphs anymore, I can draw them directly with simple vector graphics operations, and basically draw the charts any way I want!

As a result of this I have just added an option to switch the bar chart view between "simple" and "full" mode wherein "full" view you can see the 8 card boxes of this site's Leitner-based reviewing system.
