Linux enthusiasts might think the idea of running a Linux virtual machine
on Microsoft's Azure service is like finding a penguin sun tanning in
the Sahara. Linux in the heart of the Microsoft cloud? Isn't that just
wrong on so many levels?
Previously, I erroneously titled my column as "SIGALRM Timers and
Stdin Analysis". It turned out that by the time I'd finished writing
it, I had spent a lot of time talking about SIGALRM and how to set up
timers to avoid scripts that hang forever, but I never actually got to
the topic of stdin analysis.
This tutorial provides a general description of updating
Linux-based firmware and illustrates it with some specific implementations.
First, consider the sections of the memory system (Figure 1) and parts of
memory that should be updated while transferring software to a new
version.
Virtualization is now a staple of the modern enterprise. As more and more
shops switch to the virtual paradigm, managing those new virtual
resources is a critical part of any deployment. For admins using
Microsoft- or VMware-based hypervisors, powerful management tools
are available to keep their virtual houses in order.
My last several articles have covered lots of software
for
doing research in the sciences. But one important area I haven't
covered in detail is the resources available for teaching the next
generation of computational scientists. To fill this gap, you can use
the code provided through the Open Source Physics project.
Not long ago, I wrote about how awesome it is to have shell access on
a remote server. I still hold to that notion, but I received a lot
of feedback on the issue.
Every security policy provides guidance and requirements for ensuring adequate protection of information and data, as well as high-level technical and administrative security requirements for a system in a given environment. Traditionally, providing security for a system focuses on the confidentiality of the information on it.
Although it sometimes might seem as if relational databases have gone
the way of the dinosaur, making way for non-relational (NoSQL)
databases, such as MongoDB and Cassandra, a very large number of
systems still depend on a relational database.
