Maintenance / minor tweak24 September 2016
The website was updated with minor cosmetic changes to improve the theme since I changed the background color some time ago (less yellowish).

I've also updated the tools used to build the Javascripts to Closure Compiler from Google. There shouldn't be any changes, but.. you never know. If anything behaves differently compared to the last few days let me know!

Minor tweak to the site news10 September 2016
I finally added a link to each individual post... (sigh). It's important for search engines and to let users share those posts. Just one of those things that sat at the bottom of a to do list somewhere. Anyway, I've rolled my eyes enough times already. :P Point is, it's there.. so if you wanted to share a link to one of the news posts, the title of this news post is now a link !

By the way, the background color changed recently. Did anyone notice? :D I thought it was nicer on the forum so I brought the change to the main site as well. In this old post you can see the difference... Hopefully you'll agree it is nicer. I think it's funny... it seems I remove a little bit of yellow from the background color every few years. It took ten years to get to this point!

PS: Apologies to our Brazilian friends! I've noticed once in a while people have trouble answering the question on the sign up page. They are often Portuguese spellings (and probably misspellings too) for the name of the capital of Japan. I have just added more of those spellings to make the registration easier.
Working on mobile layout9 September 2016
I've started work on making the website responsive and more usable on mobile devices.

A quick glance at Google Analytics shows that a significant 24 % of visits are from "mobile", and another 8% from "tablet". I guess a "tablet" could be considered a small desktop PC and usually most websites will fit into a tablet display without a "mobile" view. As for the "mobile" devices, the top 50% of those are shared between the iPhone (31%) and iPad (17%). The other 50% are spread thin between hundreds of different devices and models such as Samsung Galaxy, Google Nexus, Kindle; Motorola, Huawei, etc.

Success!6 September 2016
Results of the performance update. I think the last performance update was a success! I'm definitely seeing a difference: most Study pages now return in less than half a second and that includes the full return trip to the server. When a Study page is not cached, the queries are still a bit slow to my liking, but still better than before so I'm satisfied with the results. If it becomes necessary, I figured another way I could improve the speed further but this update bought me a lot of time that I can hopefully focus on other things.
Bugfix5 September 2016
I fixed a rather big bug today related to the On / Kun example readings. The reading was cut after the highlighted part... The On / Kun reading corresponding tio the kanji flashcard was correct, but the full word was not spelled out so the reading could be misleading. For example 少 ("few") would show the reading すこ ... however that reading only made sense in the full word すこし. Now the full word is displayed correctly, along with the highlighted kanji reading. Thanks to Noah for letting me know!

To enable example words on your flashcards go to Account Settings > Flashcards. Example words are selected based on their frequency of use as documented in JMDICT (roughly 16000 entries in JMDICT). For common kanji where there are several suitable On and/or Kun readings, the example words will be picked at random. That way you can get more of your kanji reviews after completing RTK.
