VNC stands for Virtual Network Computing. It is a remote control computing software that allows you to view and control another PC desktop remotely over the Internet.
Once the VNC session is established, all VNC data exchange between the client and the remote computers is unencrypted. A malicious user might be able to spoof your VNC data, thus allowing the person to gain access to your computer. VNC software usually contains a VNC server and a VNC viewer program.
Secure Shell or SSH is a network protocol that allows data to be exchanged between two computers over an encrypted secure channel. PuTTY is a popular and easy to use free SSH client.
Cygwin is an emulation of the Linux/UNIX-like environment and OpenSSH for Windows.
There are free software available for you to download from the Internet to tunnel VNC traffic over SSH connection.

I am always looking out for new ways to make more money online with less effort.
Recently I came across a new innovation that you need to hear about because it may affect the way you earn with your website in the very near future.
Pay-Per-Play (PPP) is the newest and fastest growing form of online advertising. It is an online media channel that plays audio advertisements on websites that place the PPP code on their web pages.
You will get a guaranteed 100% conversion rate on your website visitors, no clicks is necessary! You may be thinking about how is this possible?
PPP audio ads will begin playing automatically as soon as your visitor arrives on the web page that is installed with the PPP code. PPP audio ads will play ads contextually that are related to the text content of any web page.
You make money every time a PPP audio ad is played on your web site. The best thing is you still get paid even if your visitors do not turn on their speakers.

Ever wonder why you are not getting the affiliates commission from the sales generated through your affiliate links? This is because there are some “smart” people around that see your affiliate ID embedded into the affiliate link. They might not click on your affiliate link, but will straight go to the main web site URL, thus you will not get paid with the commission.
Now you can hide your affiliate ID by cloaking the affiliate links for free at LinkCloakers.com in order to prevent someone from stealing your affiliates commission. Basically, it modifies your affiliate link into a link that is more difficult to be recognized.

I managed to upgrade my blog to WordPress 2.3 without much complication. I even dared to perform the upgrade before doing a backup of the database, which is strictly not recommended to do so. There was a slight compatibility issue with the plug-in I installed since the previous version. Other than that, everything went smoothly.
The built-in tagging feature is pretty useful, but there is no tags management feature. Luckily, I found the Tag Managing Thing plug-in that allows me to edit and delete the tags.

Everyone was trying their best to get a Gmail account when Gmail was first introduced. Gmail account registration was by invitation only. Gmail users were selling Gmail account invitations on Ebay. Now, Gmail has open up its account registration, allowing everyone to create Gmail account from its web site.
Nowadays, spam e-mails are accounted for more than 95 percent of total e-mails that arrive in your inbox. Unless your mail server has spam filtering protection in place, else you will end up having to retrieve all the spams to your e-mail client software and delete them one by one.
In the early days, Gmail spam filter was unable to catch spams effectively. Over the period of time, Gmail spam filter system has improved significantly. Most of the spams that reach your Gmail account will end up in the spam folder.
You will now ask about how to use the Gmail account to filter your personal POP3 e-mail account at your ISP or web hosting provider?
The answer is simple, that is e-mail forwarding.
Gmail allows you to retrieve e-mails to your e-mail clients software (eg. Outlook Express, Thunderbird, Eudora) via POP3, and send e-mails from your e-mail client software via SMTP.
Step 1
Setup e-mail forwarding in your existing POP3 account to forward all incoming e-mails to your Gmail account. If your POP3 e-mail account is hosted with a web hosting provider, most of the hosting packages include a control panel, such as Cpanel, HSphere, and etc. that allows you to setup e-mail forwarding yourself.
If you don’t have the privilege to setup e-mail forwarding, you should ask your ISP administrator or web hosting provider to setup the e-mail forwarding for you.
Step 2
Setup your e-mail client software to connect to Gmail via POP3. For information about configuring your e-mail client software, please refer to this link.
If you are unable to connect to Gmail because your company firewall is blocking traffic from going through non-standard ports, I will show you a way to overcome this problem at this link.
Step 3
Check the box to leave a copy of the e-mails in the mail server. This is optional if you wish to have a copy of the e-mails save in your Gmail account.
Step 4
Save your settings.
It’s time to check for e-mails by connecting to your Gmail account via POP3. All incoming e-mails that arrive at your ISP or web hosting e-mail account to be automatically forwarded to your Gmail account.
You should now be able to download e-mails minus all those spam e-mails that are filtered by Gmail to your e-mail client software.

However, many companies firewall block traffic from accessing through non-standard ports. The standard ports for POP3 is port 110 and SMTP is port 25.
WebMail is an Mozilla Thunderbird extension that allows users to integrate web-based e-mail accounts such as Gmail, Yahoo, Hotmail, and many others into Thunderbird. It uses standard HTTP protocol to
connect and access your web mail account. Most companies enable HTTP traffic to pass through the firewall.

The JustRecipe Forum is launched today. Anyone who is interested about cooking, recipes, food and wine is welcome to post discussion in the forum.
WordPress 2 still doesn’t have the feature to support HTTPS access to the admin area when the rest of the blog is accessed in HTTP. I don’t feel comfortable to access the admin area in unencrypted connections. I believed many people using WordPress also had the same thought with me.
Fortunately, there was a smart guy out there managed to create a WordPress plugin that secured the access to the admin area. The plugin is called Admin-SSL. The plugin supports both shared and private SSL certificates.
