Change vi Defaults To Not Display Line Numbers When Editing Files On Linux

InsightsLeave a comment

Recently I was contracted to do some work for a new client that had around 25 CentOS Linux and Ubuntu Linux servers. The client needed various system administration tasks completed such as updating the servers, modifying a couple scripts that performed automated tasks, and a couple other basic tasks. I typically use vi to modify scripts or text files on Linux servers so when I started to perform my tasks I started getting annoyed as the vi default configuration included the line numbers which makes it a pain to copy/paste from the files you are editing. You can obviously turn off the line number display by typing “:” followed by “set nonu” (both without the quotes) however that does get old. Use the information below to change the default vi configuration so line numbers no longer display by default.

Use Photoshop To Add More Space Between Letters

InsightsLeave a comment

Tonight while working on a web site for a client I was generating a header image that needed to be a specific width to fill out the header properly. The font selected by the client had the letters smashed together so I needed to add some space between the letters. I am not much of a designer so I had to play around with Adobe Photoshop until I was able to find the correct settings which happened to be named kerning and tracking. Kerning is used for a single letter and Tracking is used for a group of letters. These options are located in the Photoshop Character palette and can be modified using the steps below.

Use CSS To Make Text Wrap Around An Image, Insert Image In A Paragraph

Earlier today while working on an e-commerce store for a client I was adding a couple simple content pages such as the typical “About Us” page. Anyhow I don’t use CSS on a daily basis so I typically forget the various syntax and/or tags that I need to use to accomplish certain tasks. In this case I needed to add a couple head shot images to the bio section of the About Us page and wanted the text to wrap around the head shot images. This is easy to do but I wanted to note for others and for future reference for myself.

Recently I was tasked by a client with figuring out how to connect to their Flash Media Server for administration purposes. I personally have not ever used FMS so I didn’t even know where to begin. After trying to bring up the admin console in a browser on port 1111 and receiving an error as noted below I finally figured out that you must install a package from Adobe and make the connection through that software. I describe below the steps I took to make the connection to the clients Flash Media Server or more correctly the Flash Media Administration Console.

This past weekend my wife’s T-Mobile phone broke and I had an old iPhone 3G that I decided to jailbreak for her to use on T-Mobile’s network. After finally getting the iPhone baseband correct and on the version of the iPhone iOS that I wanted to use I had a couple loose ends to resolve which included transferring her contacts to the iPhone. Luckily most of the contacts had been saved onto her T-Mobile SIM card and after a bit of research I realized it was really easy to transfer contacts from the T-Mobile SIM card to the iPhone by using the instructions below.
