  Hi, I'm trying to write a query that returns the shortest string value in the column. For ex: if ColumnA has values ABCDE, ZXDR, ERC, the query should return "ERC".

• django multi-language (i18n) and seo

  - by fumer

  hi, I am developing a multi-language site in django. In order to improve SEO, i will give every language version a unique URL like below, english: www.foo.com/en/index.html french: www.foo.com/fr/index.html chinese: www.foo.com/zh/index.html However, Django looks for a "django_language" key in user's session or cookie to determine language in default, so,Despite which language user chose, URL is always the same. for instance: http://www.foo.com/index.html how to resolve this problem ? thank you!

• getJSON and variable scope in javascript

  - by nillls

  Hi! In order to make function calls to our back-end php code we've implemented something called an ActionProxy like this: function ActionProxy(action, input, callback){ $.post("ActionProxy.php?method="+action, { data: input}, function(data, textStatus, XMLHttpRequest){ //return data.ResponseWhatever } }); The problem we're having is that using data outside the ActionProxy is impossible due to variable scope limitations (we assume), setting var res = data.ResponseWhatever or return data.ResponseWhatever is pretty futile. How would one handle these responses most appropriately so that functions calling the actionproxy can access the response values?

• Update all table rows but top N in Mysql

  - by arthurprs

  I was trying to run the following query UPDATE blog_post SET `thumbnail_present`=0, `thumbnail_size`=0, `thumbnail_data`='' WHERE `blog_post` NOT IN ( SELECT `blog_post` FROM blog_post ORDER BY `blog_post` DESC LIMIT 10) But Mysql doesn't allow 'LIMIT' in an 'IN' subquery. I think I can make a select to count the table rows and then make an ordered update limited by 'COUNT - 10', but I was wondering if there is a better way. Thanks in advance.

• Get column name in jpa

  - by German

  Hi all, I have a query factory that takes a column name as an attribute in order to search for that column. Right now I'm passing the name of the column as a string, so it's kind of hardcoded. If the name of the column changes in the entity's annotation, that "hidden dependency" breaks up. Is there a way in jpa to retrieve the real name of the column and have it available at compile time, so I can use it in queries?

• Is there any way to group edit buttons in MediaWiki?

  - by Mark Robinson

  Is there any way to group the edit buttons displayed above the edit dialog in MediaWiki? By grouping, I mean like Word does (and even this editor) - you can add dividing lines to group them so that e.g. Bold and Italic are in one group, numbered list and bullet points in another. We've added lots of new buttons (in EditPage.php) and they are in a logical order, but at 30 buttons it is a bit overwhelming for some users.
