Gentoo Linux: eth0 Stops Working During Install Using Minimal Install CD

I started an install of Gentoo Linux this morning on a desktop at my house so I could test some browser stuff that purehate was seeing via his Gentoo laptop. I don’t think I have ever installed Gentoo but its possible a couple years back I installed it in the same scenario. Anyway I decided to download the x86 minimal install CD for the installation. After it was burned to CD I booted my desktop up and started the install. Once it was booted I configured the network interface, which in this case was eth0, and was able to test without issue to the Internet using ping. I proceeded with the installation including writing the partition table, creating the file system, and mounting my drives. The next step involved using links to open a gentoo.org URL to select a mirror and to my surprise it failed. Below I go into detail about the problem I ran into and the steps I took to resolve the issue.

Enabling FORCE_SSL_ADMIN in WordPress Breaks Image/Media Upload In The WordPress Admin

I have been having a problem with the media browser uploader for a couple days since I enabled FORCE_SSL_ADMIN in my wp-config.php file. I finally got some time tonight to look into the issue and I am embarrassed it took me so long to resolve. This was a classic example of trying to make something more complicated than it really was. The issue ended up being with a WordPress plugin I had installed called Flexible Uploader. This plugin provides all the functionality of the flash media uploader to the browser media uploader. It turns out that this plugin has not been updated in a long time and some of the URL building functions have changed in the newer versions of WordPress. Below I explain how to easily resolve the issue.

LiteSpeed Web Server: Redirect All Web Traffic to HTTPS Except One Directory Or URL

LiteSpeed web server uses the same Rewrite engine that Apache uses so most of the information you will find  on the Internet relates to Apache and not LiteSpeed. One of the projects I am working on redirects all web traffic that hits each virtual host from HTTP to HTTPS without exception. Recently it came up that we needed to do some API testing with a company that wanted to test on a development server to HTTP and not HTTPS. So I needed to figure out how to exclude a specific directory from our HTTPS Redirect Rule on one specific virtual host which turns out is really easy. Below I describe how to send all traffic except one directory to HTTPS via the LiteSpeed web admin.

Create Your Own TinyURL Engine Using Pretty Link WordPress Plugin

Long links on your WordPress blog are great for SEO purposes however when emailing people links or posting links on the web it is nice to post a manageable length URL instead. There is a plugin available for WordPress called Pretty Link that allows you to generate short URL’s with ease. There are two versions of Pretty Link available which include a free version and Pretty Link Pro which is a pay version that cost $97.  Depending on what your needs are with creating short URL’s using your domain the price is more than reasonable for Pretty Link Pro. I currently only use Pretty Link a limited amount so the free version currently serves its purpose for me though I plan to upgrade in the future to Pretty Link Pro. Below I describe some of the features of the Pretty Link WordPress plugin.

SkypeIn Call Blocking: Block Incoming Calls From Specific Numbers In Skype

It is really easy to block unwanted calls to your SkypeIn number using your Skype client. There are numerous ways to block calls into Skype such as blocking one specific number, blocking all hidden numbers, or even not allowing any calls except for people in your contact list. I use my Skype number for business so the last method is not an option for me since I receive calls from numbers I don’t recognize all the time so I personally use a combination of the first two methods. By default I block all hidden numbers and then when I receive more than one call from an unwanted number I block that specific number. Below I describe how to perform all three methods so you can choose how you want to block calls into your SkypeIn number or if you don’t want to block any calls.
