  • AWS Performance Tuning – This guide introduces best practices for tuning Riak cluster performance in the Amazon Web Services (AWS) Elastic Compute Cloud (EC2) environment.
  • Guide to Windows Batch Scripting – /* steve jansen */ – This series will share some of the tips and tricks I’ve picked up through the years of working with Windows professionally. I’ll be the first to admit the Unix shells of the world are far superior to the Windows command prompt (or even Windows PowerShell). Windows is a fact of life for most professionals writing code for coporate customers; this series aims to make life with Windows a little easier.

  • IOWait. (Sysadmin’s bedtime horror story) – […] hope this helps someone out there. The last 3 days, I have had my server crash on me every 2-3 hours. At first I thought it would be a spike in the traffic, since I couldn’t find any crash reports from Apache, and there was a spike in the traffic at this time. So I increased the resources on the server. It crashed again, every 2-3 hours […] It wasn't my case but… who knows in the future?
  • Apache mod_deflate and mod_cache issues | Devon Hillard’s Digital Sanctuary – The Problem: Using Apache mod_deflate and mod_disk_cache (or other mod_cache) together can create far too many cached files. The Background: Apache is a web server with many different modules you can load in to enhance it. Two common ones are mod_deflate and mod_cache (or mod_disk_cache).

  • /bin/bash based SSL/TLS tester: – is a free command line tool which checks a server's service on any port for the support of TLS/SSL ciphers, protocols as well as recent cryptographic flaws and more. [ via ]
  • Policy NAT for L2L VPN • – I kind of missed the wood for the trees here. The static policy NAT is failing because you are trying to map a network to a single IP address 172.20.n.1. However it's just occured, why are you doing policy NAT for the Internet. I tested in lab and if you do this
  • Encrypted Data Bags on Cloud on AWS – Many customers have asked us how they should handle shared secrets, passwords and other sensitive data in Chef and now we have a good solution. With the release of our stable-v4 stack, we introduced Chef 10 to the platform, and with it came data bags. Now with the 3.0 release of the engineyard gem, we can officially support data bags and encrypted data bags. You may be wondering what data bags are, how data bags work or how to implement data bags. This blog post will walk you through the entire process.
  • How to set disk alignment in Linux | Dirty Cache – As you might know, if disk partitions containing Oracle datafiles are not aligned with the underlying storage system, then some I/O’s can suffer from some overhead as they are effectively translated in two I/O’s. If you want more info, google for “EMC disk alignment” and you’ll find plenty of information, explaining the issue.
  • Add Private Route 53 DNS to your AWS VPC | CloudTrek – A really cool feature of Amazon’s Route 53 DNS Management Service is the private hosted DNS zone.  Basically, you get the ability to manage the DNS in your private VPC without setting up your own DNS infrastructure (yuck!) [ Just a friendly reminder Note 1: the resolution is working only inside the VPC. Note 2: if you don't have the AmazonProvidedDNS in your DHCP-OPTION you won't resolve the zone. Note 3: if you are using linux, you can use as DNS it won't work on windows 2008 Ref: ]
