Anytime you work online, you risk productivity wipeout. With a world at your fingertips it’s hard to stop from clicking on links (upon links, upon links). Avoid throwing away your precious time by making every click of the mouse a purposeful one.
With all the new mobile operating systems how do you to know which one to pick? Like Android, Palm has a webOS emulator to allow developers to test applications without physical hardware. Here is how you can test drive webOS on your computer for free.
When it comes to gathering statistics on web sites, you can never have enough. While one of the most popular method for tracking statistics is through services such as Google Analytics, log file analysis remains a reliable way to track your visitors as they are immune to script blockers. A widely used tool for log file analysis is the open source tool, AWStats.
As an IT manager, there are a lot of things you can do which directly impact your company’s bottom line. While the most obvious are direct hardware and software costs, an often overlooked aspect is energy/electricity consumption by computer systems. While servers need to be available 24/7, desktop systems only need to be available when the respective user needs it or for scheduled maintenance tasks. The rest of the time (usually more than 50% of the time), the system can stay in low power mode which reduces power usage, hence cost.
All Dell servers come with the Dell OpenManage Server Administrator software which has the ability to monitor and display system level indicators. Additionally, through the Alert Management tab you can configure actions to execute whenever an alert is triggered. Unfortunately there is no vehicle for applying uniform notifications to all events, so we are going to provide a script which configures all the alert actions to send an email notifying you of the respective event. While you could set these up manually, having a script is ideal as you can easily deploy this across multiple servers.
Unless you have a special setup, you typically only need a single IP address from your ISP to run your network. With your network sitting behind a firewall/router, you can direct your incoming traffic to the appropriate servers to handle email, web, remote connections and anything else. The problem comes when you have multiple servers which need to receive traffic from a common port. Instead of adding more public IP addresses (and cost), we are going to show you how to handle this situation using on a single IP.
A common function of many programs is the ability to send email. When working on development projects or doing product demos which utilize email, having an environment you know will work can be critical. For these situations, having a completely self contained email system, that is all emails “sent” never leave the local machine, is the answer.
There are lots of great utilities out there which do essential tasks such as monitoring and reporting that once you have configured them, they just sit in your system tray and do their job without you ever knowing. While this works great for desktop machines, this model is not ideal for server use which, typically, does not have anyone actively logged into it.
