• Getting the download count of a specific S3 object

  - by phidah

  I've got a number of S3 objects that are available to my customers. Since I'd like to bill my customers by usage, I wondered if there is any smart kind of way to get the number of times a given file has been downloaded? Alternatively, I suppose I could parse the log files provided by S3, but with 10m+ fetches per customer this might be bit of a task. Any ideas?

Describe an algorithm that finds if there is an element/s that repeat itself at least n/k times... if there is return one - do it in linear time running O(n) Imortent: now the catch do this algorithm or even pseuo-code using a constant usage of memory and running over the array only TWICE!!!

  - by Vilx-

  I've got a bit of XML I want to display on my ASP.NET website as-is (for debugging purposes), and it would be nice if it was colored. This should be easy to achieve with the right kind of XmlWriter, but I don't have the time to make one myself. Is there an existing (free) component that can do this?

• How do "modern JVMs" differ from older JVMs?

  - by Lord Torgamus

  Here's a phrase that I heard a lot throughout high school and university computer science classes: "That's not an issue for modern JVMs." Usually this would come up in discussions about overall performance or optimization strategies. It was always treated as a kind of magical final answer, though, as if it makes issues no longer worth thinking about. And that just leads me to wonder: what are the differences between the prototypical "modern JVM" and older JVMs, really?

• C++ priority queue structure used ?

  While searching for some functions in C++ STL documentation I read that push and pop for priority queues needs constant time. "Constant (in the priority_queue).

• xslt or php for rendering output

  - by Arsenal

  I'm creating something where users can upload an xml and data get's imported to the database. Now I'm building some kind of a preview page where users will get to see how their input will look once it's stored. What would be the fastest (in execution time), using XSL to transform the xml to a html page, or using php to render the output? My guess is XSL is far more suitable (+ faster) for this (and by using a DTD there's no need for code written validation, right?)
