问题 I have written some DAO methods that do bulk updates / deletes with HQL but I see that when the query is executed the entities in memory are not sychronized (the cache is not updated). Say, I have a collection of Projects with a collection of Groups each and I want to delete all Groups. I can iterate the Groups and delete each but I prefer to run a bulk delete with HQL and IN operator. However, the list has the old objects after the query is executed. I realized that I have to refresh the

问题 I've created an NVD3 multiBarChart and placed it in a jQuery resizable container. When resizing the chart, each render incurs the same delay as when the chart is first drawn: staggered left-to-right delayed drawing of the bars.

Haven't yet inspected the NVD3 JS and am hoping not to need to. Fiddle: http://jsfiddle.net/a5Fnj/10/

问题 We have an app which I've coded up and for ages now I've pushed updates to it through ClickOnce. The app sits on our main file server. But every time I push out an update I get asked what I've changed! Is there any way to provide a personalised description of an update with ClickOnce which would be user-friendly?

问题 How do you run a long PHP script and keep sending updates to the browser via HTTP? Something to do with output buffering but I don't know exactly how. 回答1: Output Buffering is thinking in the right direction, you start output buffering with ob_start() just like you would with sessions ( session_start ) somewhere in the top of your script, before any output is sent. Then, you can use ob_flush and flush to keep flushing the output. For example, if you are in a foreach loop and at the end of
