Power and Chiller planning for server rooms.
This month, we have a short primer on power & chiller planning for server rooms.
When laying out a server room or even a wiring closet, power utilization & cooling estimates are important.
Even if you are trusting the Facilities dept to do it right, you still need to have an idea of whether they really are getting it right
before you burn up your equipment.
This is a very brief look at power wiring, capacity and cooling.
Texx has over 20 years data centre experience, some in rooms that could be used as a sauna.

Not Your Father's Assembly Language
Just as high-level languages have evolved over the past 50 years, so has assembly language. Alas, assembly language has been unfairly demonized by software engineers whose main experience with assembly language was in a college or university assembly language course being taught with an assembler whose feature list came straight from the 1960s. This talk will discuss why assembly language is still relevant and will describe a more modern implementation of assembly language (HLA - the High Level Assembler), emphasizing the portability aspects of HLA.

DevOps: What it means for your job and your tools.
Across the IT industry there is a growing awareness of a disconnect between what is traditionally considered development activity and what is traditionally considered operations activity. This disconnect often manifests itself as costly inefficiency, frustrating bottlenecks, and morale killing conflict. In response to this awareness, a new movement called "DevOps" is on the rise. As the technology press and analysts continue to uncover this trend, it will undoubtedly fall to us individual practitioners and managers to evaluate how DevOps will impact our own organizations. This presentation will provide an introduction to DevOps, examine best practices and tooling that DevOps encourages, and provide tips for staying abreast of the latest DevOps developments.

Linux Network Troubleshooting
In this talk, Kyle Rankin will break down network troubleshooting on a Linux system into a common set of tests and steps that you can apply to a majority of networking problems. Included will be basics of DNS troubleshooting, Layer 1, Layer 2, and Layer 3 troubleshooting, and an example problem solving session.

Whether running a simple grep command or writing a big Perl program, a thorough understanding of regular expressions is an essential skill for any system administrator. The talk will describe the history, syntax, and best practices for regular expressions; how a well-written regular expression can dramatically improve the speed of pattern matching; and give tips for using regular expressions in Perl programs.

When your Linux system has problems, there are a number of ways to track down and solve them. In this talk I will discuss my overall philosophy for troubleshooting and then follow up with more specific examples of how to diagnose common problems on Linux systems. This talk will be more server-focused but most things should apply to desktops as well.

SQL isn't everything
by Jesus Monroy
Today there is a push for SQL-based solutions, such as Oracle, DB2 or Mysql. While these solutions are excellent for certain classes of problems, they don't work well for many things. Many issues arise including: scaling, performance and development cost.
For most applications today, people struggle with managing the database, security and performance. For many, their "data sets" are small enough, or infrequent enough, that a simple flat file will not only suffice, but excel. In addition, benchmarks of yesteryear (of 3-4 thousand records) being the crossover point for a full blown database are outdated.
In this talk we will discuss other solutions, starting with the power of basic flat files and flat memory arrays. Then an extended discussion on Berkeley DB, sleepycat dbm, local and network-distributed hash tables and other systems that can scale in size and performance to Google levels.

Allison Randall on the Parrot Virtual Machine
"Parrot is a register-based virtual machine being developed using the C programming language and intended to run dynamic languages efficiently. It uses just-in-time compilation for speed to reduce the interpretation overhead. It is currently possible to compile Parrot assembly language and PIR (an intermediate language) to Parrot bytecode and execute it.
Parrot was started by the Perl community, and is developed with help from the open source and free software communities. As a result, it is focused on license compatibility (Artistic License and GNU GPL), platform compatibility (Unix, Microsoft Windows, Mac OS X and Classic, VMS, Crays, Windows CE, Palm OS, and others), processor architectures compatibility (x86, SPARC, DEC Alpha, IA-64, ARM, Palms, old Macs), speed of execution, small size (around 700k depending on platform), and being flexible enough to handle the varying demands of Perl, Python, Tcl, Ruby, Scheme, and other dynamic languages. It is also focusing on improving introspection, debugger capabilities, and compile-time semantic modulation." , even Lua .

Where'd My Files Go? A Guide to Modern Ubuntu Distributions
While you might not be able to tell at a glance, a lot has changed behind the scenes on a modern Ubuntu system. For example, did you know that Ubuntu is phasing out System V init? That you can't loopback-mount the initrd? In this talk Kyle discusses the changes Ubuntu is making to what we might consider the traditional Linux system. There's a little something for everyone in the talk. For Linux newbies who are curious about what's under the hood Kyle covers the traditional and modern boot process including how init works followed up by a guide to where important files are in Ubuntu. For the experienced Linux user Kyle will show you how (and why) things have changed and where you can look now when you want to, for instance, change the default runlevel on an Ubuntu system.
How DNS Works
In this talk Kyle will cover the basics of how DNS (Domain Name System) works. The talk will include a short history of the service, how it works today, and a step-by-step walk-through of what happens between entering a domain into a web browser and getting back an IP address. Also covered is how you could use this new-found knowledge to take down the Internet. Specific implementations of DNS (BIND, djbdns, PowerDNS) will not be covered.

Meeting - Luke from prgmr.com
Prgmr.com provides low-cost, high-flexibility webhosting using Linux, NetBSD, and Xen.
Prgmr.com Xen hosting News
prgmr.com status can now be seen on our Xen hosting blog. If you want older news, see our historical status. Please note, all new status goes on the blog.
We cerified our new server as good on Jan 22, so ordering for Xen-based virtual private servers is open again.. We do occasionally have problems keeping up with demand so the signup page goes offline every now and again. Rest assured we are running as hard as we can to get new capacity up and in place. .
He informs me:
"I plan on doing a high-level overview of virutalization technologies,
drilling down into Xen, with a focus on using xen to split large hardware
into small virtual private servers that are owned by mutually untrusted
I want to explain a little bit how to use your Xen VPS as a customer.
(most of this part will be specific to prgmr.com, but we use standard
tools, xencons and PVGRUB to manage things, along with a few simple
shell scripts which I can share. Any of you could duplicate my setup without
too much effort.)
I also want to give a short talk about choosing hosting providers from
a customer perspective. When does it makes sense to rent a VPS, when it makes
sense to rent a server, and when it makes sense to co-locate your own

Our aims are to continue the democratization of geo data and to expand access to open geo data through a range of simple yet powerful tools and APIs.
I enjoyed the talk she gave for SVLUG.org in January, so I asked her to visit us in March to talk about openstreetmap. She did confirm.
