• Which JVMs do not support direct java.nio.ByteBuffer?

  - by Joe Holloway

  The release notes for Java NIO (in Java 1.4+) state that support for direct ByteBuffers is an optional feature. I am curious which JVM vendors/flavors do not support it? Should a JNI library always code for managed ByteBuffers and relegate direct ByteBuffers as an optimization? Thanks

• Grails not executing on IntelliJ (NoClassDefFoundError)

  - by fabien7474

  Hi, I have upgraded my application from grails 1.2.2 to 1.3.1-RC1. While things seem to work when executing grails from command prompt, I cannot make it run from my IDE IntelliJ (last development version). The error I got is: Error executing script RunApp: net/sf/json/JSONException ... Caused by: java.lang.ClassNotFoundException: net.sf.json.JSONException It seems that the library json-lib.jar is not in the IntelliJ classpath. Do you know how can I solve this?

• Memory layout of executable

  - by Ross

  Hi all, When loading an executable then segments like the code, data, bss and so on need to be placed in memory. I am just wondering, if someone could tell me where on a standard x86 for example the libc library is placed. Is that at the top or bottom of memory. My guess is at the bottom, close to the application code, ie., that would look something like this here: --------- 0x1000 Stack | V ^ | Heap ---------- Data + BSS ---------- App Code ---------- libc ---------- 0x0000 Thanks a lot, Ross

• Spreadsheet::WriteExcel Memory Usage

  - by Stomped

  Hi; I'm trying to create a multi-sheet excel document, and thus far I'd been doing it in PHP - but using PHPExcel was eating up 70MB of RAM for about 60,000 spreadsheet cells total. I'm wondering if anyone has experience with Spreadsheet::WriteExcel and if it has problems with creating very large documents. I'd just give it a shot but I'm very inexperienced with Perl and it could take me quite a bit of time to get this up and rolling even if for a test, and I thought someone here might have insight for me.

  We need to write a .Net (C#) application that monitors all mail activity through a POP, SMTP and Exchange Server (2007 and later) and essentially grab the mail for archiving into a document management system. I realise that the way to monitor each type of server would probably be different so I'd like to know what the best (most elegant and reliable) way is to achieve this. Thanks.

• Totally Sweet Horizontal Rules in LaTeX

  - by Arcane

  I have been trying to find a way to easily drop a nice horizontal rule into a LaTeX document. \hline just makes a line across the page. It would seem that some package must provide something that is maybe half a page wide, with little bedknobs on the ends or something to act as a nice section marker for paragraphs. Any ideas? Or am I boned, and need to come up with my own macro to create such a beast?
