问题 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? 回答1: If they don't have to do anything with each other: No. You might need to restart the VM for one of the applications, which would result in a downtime for both. 回答2: While many would recommend decoupling these subsystems I would take the opposite approach.

问题 I'm looking into using virtual machines to host multiple OSes and I'm looking at the free solutions which there are a lot of them. I'm confused by what a hypervisor is and why are they different or better than a "standard" virtual machine. When I mean standard I going to use the benchmark virtual machine VMWare Server 2.0.

问题 According to many, the somewhat common Double-Checked Locking idiom is broken for java unless you're running 1.5 or later and use the volatile keyword. A broken double-checked lock sample: // Broken multithreaded version // "Double-Checked Locking" idiom class Foo { private Helper helper = null; public Helper getHelper() { if (helper == null) synchronized(this) { if (helper == null) helper = new Helper(); } return helper; } // other functions and members... } The sample comes from this

问题 I've been working with a Google Cloud debian VM and had no problem at all doing super user tasks using sudo (sudo was not asking for password).
