Download HTTrack and SiteSucker

HTTrack is available for Windows, Linux and Mac. Click here to download HTTrack.

Alternatively, there is a software for OSX and iOS called SiteSucker developed by SiteSucker.

SiteSucker automatically downloads Web sites from the Internet. It does this by asynchronously copying the site’s Web pages, images, backgrounds, movies, and other files to your local hard drive. Just enter a URL (Uniform Resource Locator), press return, and SiteSucker can download an entire Web site.” (Cited on: http://wlanbook.com/httrack-like-website-copier-offline-browser-for-mac-os-x/)

What is HTTrack Web Crawler/ Browser?

HTTrack is a free and open source Web crawler and offline browser, developed by Xavier Roche and licensed under the GNU General Public License Version 3.

HTTrack allows users to download World Wide Web sites from the Internet to a local computer.[5][6] By default, HTTrack arranges the downloaded site by the original site's relative link-structure. The downloaded (or "mirrored") website can be browsed by opening a page of the site in a browser.

HTTrack can also update an existing mirrored site and resume interrupted downloads. HTTrack is configurable by options and by filters (include/exclude), and has an integrated help system. There is a basic command line version and two GUI versions (WinHTTrack and WebHTTrack); the former can be part of scripts and cron jobs.

HTTrack uses a Web crawler to download a website. Some parts of the website may not be downloaded by default due to the robots exclusion protocol unless disabled during the program. HTTrack can follow links that are generated with basic JavaScript and inside Applets or Flash, but not complex links (generated using functions or expressions) or server-side image maps.

What is Offline Browser/ Reader?

An offline reader (sometimes called an offline browser or offline navigator) is computer software that downloads e-mail, newsgroup posts or web pages, making them available when the computer is offline: not connected to the Internet. Offline readers are useful for portable computers and dial-up access.

What is Web Crawler?

A Web crawler is an Internet bot which systematically browses the World Wide Web, typically for the purpose of Web indexing. A Web crawler may also be called a Web spider,[1] an ant, an automatic indexer,[2] or (in the FOAF software context) a Web scutter.[3]

Web search engines and some other sites use Web crawling or spidering software to update their web content or indexes of others sites' web content. Web crawlers can copy all the pages they visit for later processing by a search engine which indexes the downloaded pages so the users can search much more efficiently.

Crawlers can validate hyperlinks and HTML code. They can also be used for web scraping (see also data-driven programming).

What is Web Scraping?

Web scraping (web harvesting or web data extraction) is a computer software technique of extracting information from websites. Usually, such software programs simulate human exploration of the World Wide Web by either implementing low-level Hypertext Transfer Protocol (HTTP), or embedding a fully-fledged web browser, such as Internet Explorer or Mozilla Firefox.

Web scraping is closely related to web indexing, which indexes information on the web using a bot or web crawler and is a universal technique adopted by most search engines. In contrast, web scraping focuses more on the transformation of unstructured data on the web, typically in HTML format, into structured data that can be stored and analyzed in a central local database or spreadsheet. Web scraping is also related to web automation, which simulates human browsing using computer software. Uses of web scraping include online price comparison, contact scraping, weather data monitoring, website change detection, research, web mashup and web data integration.

Web scraping related traffic has increased during recent years. On average, 23% of all traffic was scraping-related in 2013.

What is Search Engine Optimization?

Search engine optimization (SEO) is the process of affecting the visibility of a website or a web page in a search engine's unpaid results - often referred to as "natural," "organic," or "earned" results. In general, the earlier (or higher ranked on the search results page), and more frequently a site appears in the search results list, the more visitors it will receive from the search engine's users. SEO may target different kinds of search, including image search, local search, video search, academic search,[1] news search and industry-specific vertical search engines.

As an Internet marketing strategy, SEO considers how search engines work, what people search for, the actual search terms or keywords typed into search engines and which search engines are preferred by their targeted audience. Optimizing a website may involve editing its content, HTML and associated coding to both increase its relevance to specific keywords and to remove barriers to the indexing activities of search engines. Promoting a site to increase the number of backlinks, or inbound links, is another SEO tactic.

The plural of the abbreviation SEO can also refer to "search engine optimizers," those who provide SEO services.

List of Mac OS X (Yosemite) Shortcut Keys

The following tips were copied from http://www.techlicious.com/tip/the-most-useful-mac-keyboard-shortcuts/.

Many functions and features in OS X Yosemite are accessed and controlled by swiping, flicking, tapping and pinching on the surface of a trackpad (or on the top of Apple's accessory Magic Mouse), as well as by pointing and clicking. But like operating systems of yesteryear, Yosemite also lets you use a keyboard alone to summon a feature or function.
In fact, Yosemite contains so many "keyboard shortcuts" — combinations of key presses that invoke a command — that an Apple webpage lists hundreds of them. And if those aren't enough, you can create your own shortcutsby browsing to Apple menu > System Preferences and selecting Keyboard. Click Shortcuts, select app shortcuts and then click Add (+).
What follows here is our choice of the most useful keyboard shortcuts in Yosemite (and all OS X versions, starting with OS X 10.2 Jaguar), plus a selection of our favorite ways to control the Mac OS with trackpad swipes, flicks, taps and pinches.

Trackpad Gesture Controls

Perhaps the most fun way to use Mountain Lion is with gesture controls, and our favorites are listed below –– but you'll find a lot more, and see video demonstrations of them all on Apple's Mountain Lion gestures explanation page.
Show Safari Tabs – Pinch in with two fingers to reveal all open tabs at once (navigate among them with a two-finger swipe left or right; point and click or tap on a tab to open it)
Three-Finger Drag – Move a selected item from one place to another on the desktop or within an active window (where allowed)
Tap-To-Zoom – Double-tap the trackpad with two fingers within a PDF or web page to zoom in where the cursor is positioned (or zoom back out to a normal view)

Show Desktop – Spread your thumb and three fingers to reveal the desktop (when you're otherwise in an open window or active application)
