Although modern routers handle most functions automatically, some applications will require you to manually forward a port to that application or device. Fortunately, it’s really simple to do if you know where to look. What Is Port Forwarding? There are plenty of projects we’ve covered that use your computer as a server for other devices. When you’re inside of your network, most things will work fine. But some apps, if you want to access them when you’re outside your network, make things significantly hairier....

Apple users have been swiping, pinching, and rotating Mac’s user interfaces to their fingers’ content. In today’s article, we’ll show you how to do groovy things like expanding and reducing windows, and changing desktops using finger gestures. To accomplish this, we’ll use a piece of software called TouchEgg, which enhances Ubuntu’s multi touch capability by allowing us to configure actions to the finger gestures that TouchEgg supports. If you’re a Windows user and like the idea of finger-gestures, we also wrote a tutorial on how to enable MacBook-Style finger gestures on Windows....

Some who say this are pretty humble, though they probably know quite a bit about PowerShell. Others tend to think knowing about PowerShell qualifies as knowing how to use it. For those who don’t know how to use it, which is still a large portion of the systems support and engineering crowd, it can be quite a daunting thought to think about where to even start with utilizing PowerShell. You’ve heard countless technical speeches, read pages of articles, and have had plenty of conversations with peers about all that it can do for you....

What Is Image Hardening? “Hardening” an image refers to analyzing its current security status and then making improvements to address any concerns. Picking a prebuilt base image like ubuntu:latest may seem straightforward but using it as-is could expose you to lurking threats. It’s a bit like provisioning a new bare metal server from the Ubuntu install image, then never updating it. Like that install image, Images on Docker Hub can come with outdated software packages too....

After upgrading Firefox 3 to version 4, when you first launch the new release the interface is drastically different. If you find you are more partial to the Firefox 3 interface, with a few configuration changes, you can easily make Firefox 4 look like its predecessor.

Zenity adds graphical interfaces to shell scripts with a single command. Shell scripts are a great way to automate repetitive tasks, but they’re normally confined to the terminal — Zenity brings them out of the terminal and onto your desktop. We’ve given an introduction to shell scripting in the past. You don’t have to be a programmer to get started with shell scripts — they require little more than knowledge of Linux terminal commands....

Have you ever safely removed your USB device only to see that the LED activity light on your device remains on? This is caused by a change to Windows that has affected every version since Windows Vista. Here’s how to fix it. Note that we’re not necessarily recommending you apply this change unless you need it. Thanks to reader André Torga for this solution. Why is This Happening? Back in the days of Windows XP, when you safely removed a USB device the device was marked as removed and the USB hub port to which the device was connected was marked as disabled, which means that the device could no longer receive USB power and therefore the LED status light would turn off....

Ubuntu’s Grub boot loader lets anyone edit boot entries or use its command-line mode by default. Secure Grub with a password and no one can edit them — you can even require a password before booting operating systems. Grub 2’s configuration options are split across multiple files instead of the single menu.lst file Grub 1 used, so setting a password has become more complicated. These steps apply to Grub 1....

GParted is a full-featured, graphical partition editor that acts as a frontend to a variety of Linux terminal commands....

Incorporating error budgets into your application reliability strategy provides a methodical approach for balancing risk-taking with stability. Error budgets acknowledge that occasional outages, buggy deployments, and simple mistakes are inevitable. Their role is to tell you how many of these incidents you can endure. The available error budget also decides whether your next task is building a new feature or tackling another bug fix. What Is an Error Budget? A service’s error budget is simply a measure of the maximum time it can be in a failed state without incurring contractual, financial, or regulatory penalties....

We previously covered watching Netflix on Linux and concluded that using a virtual machine was your best bet. There’s now an even better solution – a “Netflix Desktop” app that allows you to watch Netflix on Linux. This app is actually a package containing a patched version of Wine, the Windows build of Firefox, Microsoft Silverlight, and some tweaks to make it all work together. Previously, Silverlight would not run properly in Wine....

While many people feel searching in Windows is less than ideal, 7’s abilities are fairly amazing. The big trick to unlocking them, however, lies in Advanced Query Syntax. Using these advanced operators can make finding files dead simple. Advanced Query Syntax Windows 7 eschews a proper “Advanced Search” option in favor of using Advanced Query Syntax. It was developed alongside the Windows Search tool and has been seamlessly baked into 7’s goodness....

What loophole? As they document over at Digital Inspiration, Pandora seems to skip the IP location check for requests coming in through HTTPS. You simply need to install an extension for your web browser that enforces HTTPS (such as HTTPS Everywhere for Firefox and HTTPS Everywhere for Chrome). Install them, open Pandora, and you’re in business. Listen to Pandora Anywhere Without Using a Proxy [Digital Inspiration]

As of Ubuntu 10.04, the minimize, maximize, and close buttons on all windows were moved to the left side and the system menu was removed. Prior to version 11.10, you could use several methods to restore the original button arrangement. To move the windows buttons in 10.04, 10.10, and 11.04, you could use Ubuntu Tweak or the Gnome-Art Manager or manually move the buttons using the Configuration Editor (gconf-editor). However, in Ubuntu 11....
