How many threads can be created by the JVM

Another option is to have the JVM host inside your JNI code.Give an estimate formula for the maximum number of threads that can be created:(maxprocessmemory-jvmmemory-reservedosmemory)/(Threadstacksize) = number of threadsFor jdk1.5, assume that the operating system retains 120M of memory:1.5GB JVM: (2GB-1.5GB-120MB)/(1MB) = ~380 threads1.0GB JVM: (2GB-1.0GB-

This means that all applications can be started in a blink of an eye and respond immediately to user input. Puppylinux can be started from flash cards or any USB storage device (this is flash-puppy), or CDs (this is live-puppy ), or zipdisk and LS/120/240 superdisk (t

Basic Ubuntu partition knowledge

I have sorted out basic knowledge about Ubuntu partitioning and provided a reference for new Linux beginners. /Boot partition, which contains the kernel of the operating system and the files to be used during system startup. It is necessary to create this partition, because most PCs are subject to BIOS restrictions, moreover, if you have a separate/boot partition, the computer can still start even if the primary root partition has a problem. The partition size is about 60 mb-
