Review: Cloud at Cost

October 28th, 2013

Cloud at Cost Main Page Screenshot Cloud at Cost is a new company offering very low cost virtual servers. For their first 10,000 nodes, they’re offering a $35 one time setup fee to get a virtual server for life (of the company). There are additional $70 and $140 one time plans for slightly larger virtual servers, or the option for $1, $2 or $4 per month. I decided to give one of these virtual server plans a try. There were quite a few hickups. I wouldn’t say they’re production ready quite yet, but if you want a server to play around with, the price is right, and their services are certainly worth that price.

Discoverying Friend List Changes on Facebook with Python

October 15th, 2013

Unfriendfinder was a Firefox plugin which allowed Facebook users to detect when people left their friend list or deactivated their accounts. After three years of development, Facebook requested the removal of the extension due to violation of their terms of service. The author chose not to fight the request. In response, I’ve created sumfriender, a Python script that can detect friend list changes as well as import previous friend lists from the Unfriendfinder Firefox plugin and grease monkey scripts.

Removing the Tracking Image from Alfresco

August 4th, 2013

Alfresco is an enterprise document management system. There is a free Community Edition that is open source, but its web interface pulls in an image from their official website that can be used to remotely track usage. This tracking image is added via Javascript and cannot be removed by simply changing a template. It is hard coded into a core class. This tutorial goes through the steps needed to patch the Alfresco WAR file in order to remove the tracking image. It has been tested for Alfresco 4.2c and may need to be adjusted for other versions.

Invalid partition table in VMWare ESX

February 6th, 2013

Anyone who has expanded a drive in Linux knows it’s a two step process. First, the partition table must be altered to include the new space. Second, the file system must be expanded to make use of the new space within its partition. It’s a fairly straightforward process I’ve done many times, but I ran into an interesting issue when attempting this within VMWare.

Copy Reddit Subscriptions from One Account to Another

February 6th, 2013

For those of you who use Reddit, if you’ve ever wanted to abandon one account for another, or just copy your subscriptions between your primary and your throw-away account, I’ve written a Python script called copy_reddit. I uses the praw API to copy both subscriptions and friends lists.

Reassigning DNS Entries in Windows/Active Directory using Powershell

October 7th, 2012

Typically, internal DNS entries for websites must be different than the external addresses due to NAT issues. If your organization has a lot of web sites that exist on either a single server or a set of identical servers behind a load balancer, it’s best practice to have all DNS entries be CNAME records to either that particular server’s DNS entry or the entry for a server farm’s load balancer. Recently I was involved in a mass server migration where actual IPs were used throughout a Windows DNS server. The following is a Power Shell script designed to rename DNS records in mass on an Active Directory Domain Controller.
