The advantage of using an email client is that you don't have to open a web browser and log in to your mailbox every time; supports for new email reminder; allows to send emails to third-party applications (e.g., Evernote, Todoist, etc.), and so forth. Therefore, users who need to send and receive emails frequently always tend to use a desktop email client, rather than any web browser.

When you've tried many ways to clean up and optimize your Windows system, but have seen no obvious results (system or program launches and runs slowly, or even crashes easily), do remember to perform defragmentation to your disk, then everything may be fine. As we all know, there have been so many free or commercial disk defragment software, such as Diskeeper, PerfectDisk, Contig, JkDefrag, UltimateDefrag, Defraggler and Ashampoo Magical Defrag.

To learn 3D game development with limited pockets, I guess you've tried many classic, free, open-source game development engines like TV3D (Truevision3D), OGRE and Irrlicht Engine. By contrast, the pros of TV3D are easy to learn and get started with; its cons are that it was built based on the ActiveX control and requires the RunTime DLL to be registered before running; OGRE is better than Irrlicht in that it has a capable and vigorous engine framework, and supports for extending new functionality in the form of plug-ins (this is better than Irrlicht); but its downside is that it's not easy to get started with.

Tiled (full name: Tiled Map Editor) is currently the most popular, powerful and flexible tiled map/level editor for all types of 2D games, developed by Thorbjørn Lindeijer in 2008 (written in Java, therefore it's cross-platform). It is identified as an edge tool for 2D game developers to quickly create game maps.

In some cases, we need to remove the background of the main character in a photo (that is, separate the wanted object from the photo), then use it for many other purposes. Examples include uploading product images to eBay, preparing photos for a job hunting or online dating website, placing it in other backgrounds, creating photo collages, etc. For similar needs, almost all of us know that Adobe Photoshop is specially designed to do just that. But most people don't want to learn it for this unless they are doing it for a living.
