I was looking at using Amazon's EC2 service after reading this article: http://www.ibm.com/developerworks/java/library/j-javadev2-4/index.html But then I wondered if there's any sense in paying for the service if really all I'm interested in is using one of their preconfigured VMs for getting java web application off the ground quickly....
I'm trying to find a way to limit the memory available for the Python VM, as the option "-Xmx" in the Java VM does. (The idea is to be able to play with the MemoryError exception) I'm not sure this option exist but there may be a solution using a command of the OS to "isolate" a process and its memory. Thank you. ...
I have a Java app which is packaged up using JarBundler. The app is fairly CPU intensive (lots of big Collection.sort() calls). On Mac OS, the app runs slow and sluggish when using the 64-bit JavaApplicationStub. This JavaApplicationStub file is launching the Java 64-bit VM. I found an old JavaApplicationStub file which is 32-bit onl...
I have been asked to do the following: a) Build a VM for a subversion server b) Figure out an autobuild system and regression test system c) Write documentation or simple instructions to get people started with subversion I am not really sure what these instructions mean - although I have a vague idea. If you know could you provide som...
I'm really begining to learn Smalltalk. Now I'm using Squeak, but there is any way to develop in Smalltalk without using VMs, but something like an IDE? ...
Hello, I want self-education purpose implement a simple virtual machine for a dynamic language, prefer in C language. Something like the Lua VM, or Parrot, or Python VM, but simpler. Are there any good resources/tutorials on achieving this, apart from looking at code and design documentations of the existing VMs? Thanks in advance for ...
I just added "-Djava.library.path=" to the "VM Arguments" under Run Configuration in Eclipse and everything works fine until I tried to add an external JAR file. I get the following error: java.lang.UnsatisfiedLinkError: no rxtxSerial in java.library.path thrown while loading gnu.io.RXTXCommDriver Exception in thread "main" java.lang.U...
I want to compile gcc so i can use the mips R2000 microprocessor compiler inorder to use NestedVM a way of targeting any executable to the java vm; but I don't want it to compile the modules for other languages than mine or architectures other than the R2000 or the Mips family. ...
Hi, I'm running a piece of software listening on a particular port inside an Ubuntu VM using VMWare fusion on OS X. I can connect to the port from OS X but I can't get to it via other, separate machines. I suspect that the OS X firewall is blocking access but I'm not sure how to verify that or really what port to open. I can't imagine ...
I'm reading an article about Xen, a virtual machine monitor. They say that an operating system requires some modification in order to be able to act as a guest OS on top of Xen. Now, for an OS like Linux, I can understand what a "modification" might mean but in the case of an OS like say, Windows XP, what does it mean? I mean, XP is clos...
Im developing a website using VS2008 on Windows 7. I am running a VM with IE6 on it and want to test that the site works ok on IE6. On the VM IE6 browser I type http://192.168.0.100/default.aspx since my router gave the windows host that ip address but the browser errors with : Cannot find server or DNS Error I can ping the host though t...
I'm thinking about writing my own little language. I found a few options, but feel free to suggest more. JVM Parrot OSA A lot of languages are using the JVM, but unless you write a Java-ish language, all the power the stdlib gives you is going to feel ugly; It's not very good at dynamic stuff either. Parrot seems a good VM for deve...
I want to run multiple Erlang applications, one being Riak and another being a web server. Should I run them in the same of separate Erlang VMs and why? ...
There is a thread discussing Darwin notifications being sent after a screenshot is taken. Does this apply to websites viewed via Safari? Do the same restrictions apply to PC sytems? Would taking the picture via a Python script in Linux or running Safari in a VM circumvent detection? ...
Aside from the ease of use of the multiprocessing module when it comes to hooking up processes with communication resources, are there any other differences between spawning multiple processes using multiprocessing compared to using subprocess to launch separate Python VMs ? ...
What are some fundamental Feature/Architectural difference between the BEAM and JVM? Yes I know: one was originally built around java and the other built around erlang I understand the JVM (somewhat) and want to compare their structures For example I know that the JVM has one Global GC and BEAM has one per process ...
I'm currently working on a component of a trading product that will allow a quant or strategy developer to write their own custom strategies. I obviously can't have them write these strategies in natively compiled languages (or even a language that compiles to a bytecode to run on a vm) since their dev/test cycles have to be on the orde...
I am looking for a tool that will allow me to monitor and control programs running inside a Windows VM from the Linux host machine. I realize that this is similar to what a rootkit would do, and I am completely happy to use some hacker software if it provides the necessary functionality (and if I can get it in source-code form). If I ca...
Several databases I've been looking at recently implement a virtual machine internally to perform the respective data reads and writes. For an example, check out this article on SQLite's virtual machine they call the 'VDBE'. I'm curious as to what the benefits of such an architecture are. I would assume performance is one but why would a...
Is there a compendium of virtual machines and languages derived or inspired by Lua? By derived, I mean usage beyond embedding and extending with modules. I'm wanting to research the Lua technology tree, and am looking for our combined knowledge of what already exists. Current List: Bright - A C-like Lua Derivative http://bluedino.ne...
