## can we help with the db?

Seems like poor old LtU has been down a fair bit on and off of late. Is it something we can do much to address easily? Even if it is just/only via moral support? :-} Thanks for the effort of keeping the old blunderbuss that is Drupal reanimated when needed.

## Paged topics

Is it just me, or is not the ui/ux of multi-page topics just not good? Could there be a way to fix it or to enforce things can't be bigger than one page, or can we all start teaching ourselves that we should start new pages or something?

When I go to the "recent posts" and see some posts on some topic, I click on the topic title (not the individual *'s new posts in the "recent posts" list) and then if they are on anything other than page 1 i can't find them.

## LtU database problem

On posting a comment, I get:

user error: Incorrect key file for table './ltu/cache.MYI'; try to repair it
query: DELETE FROM cache WHERE expire != 0 AND expire
The comment is posted, but the above sounds wrong. 

## upvoting?

Does Drupal have a plug-in for supporting up/down voting things? I want to tell people who posted that i'm excited about their post even though i am too uneducated/ignorant/clueless to be able to actually post anything relevant other than, "w00t!" Can somebody pretty please install such a feature? :-) It would be nice to be able to sort the "Recent Posts" by that as well. :-)

I added a new category "Scientific Programming" for discussions of, well, issues related to languages targeting scientific programming.

The site math viewer is consistently crashing my iPad; it makes a note that it is trying to load something math.js for awhile before Safari just dies. Either this is an iOS issue, or an iOS + great firewall issue (if the font files aren't hosted locally, they are usually hosted by a blocked-in-china google).

## LtU now supports Mathjax

LtU now supports MathJax, which allows the use of TeX markup in posts and comments. Note that only TeX/LaTeX markup is currently supported - the alternate MathML format conflict's with the blog's HTML sanitization.

This enhancement is dedicated to neelk, who most recently suggested this feature just over a year ago.

When I went searching for a bit of Mathjax-compatible LaTeX that was relevant to programming languages, the first good example Google found for me was on Neel's blog:


Copy-pasting the above and making it work immediately made it clear that we're going to need a package of useful macros. But it's a start. Feedback welcome.

Note that MathJax rendering is entirely client-side - if you don't see a well-formatted formula above, check the MathJax browser compatibility page and their FAQ.

## How is LtU doing?

I thought it was just summer, but now that fall is here, the site still feels kind of quiet.

maybe replace

"complete" http://merd.net/pixel/language-study/diagram.html

with
http://rigaux.org/language-study/diagram.html

## Links in long topics don't work

I tried to post a link to my posting:

http://lambda-the-ultimate.org/node/4655#comment-74144

but it just posts a link to the first page of a 2-page discussion and doesn't connect to my posting. Seems broken.
