An organizationally unique identifier (OUI) is a 24-bit number that uniquely identifies a vendor, manufacturer, or other organization.
OUIs are purchased from the Institute of Electrical and Electronics Engineers (IEEE) Registration Authority by the assignee (IEEE term for the vendor, manufacturer, or other organization). They are used to uniquely identify a particular piece of equipment through derived identifiers such as MAC addresses,[1][2] Subnetwork Access Protocol protocol identifiers, World Wide Names for Fibre Channel devices.[3]
In MAC addresses, the OUI is combined with a 24-bit number (assigned by the assignee of the OUI) to form the address. The first three octets of the address are the OUI.

Everything curl is an extensive guide to everything there is to know about curl, the project,
the command-line tool, the library, how everything started and how it came to be what it is
today. How we work on developing it further, what it takes to use it, how you can contribute
with code and bug reports and why all those millions of existing users use it.
This book is meant to be interesting and useful to both casual readers and the somewhat
more experienced developers, and offers something for you all to pick and choose from.
Don't read it from front to back. Read the chapters you are curious about and go back and
forth as you see fit.
The history of Ajax is similar to many other apparent overnight sensations. Although Ajax seemed to come
out of nowhere, in reality it had been percolating for a while. Several years of work spread across the Web
went into creating the tools and patterns that came together under the Ajax banner. Throughout the dHTML
era of the original Internet bubble and into the dark years after the dot-com crash, developers around the
world were unlocking the unexpected power of JavaScript to bring new and exciting application patterns to
the web.
Too often our DOM scripting adventures are
focused on the new glittery features and stray from the basics of good, clean web application
design. As a result, I’ve emphasized best practices throughout the book and provided solutions that
focus on usability and accessibility for both the end user and you, the developer or designer.
You can keep this book next to your computer as a reference or read it cover to cover—it’s up to
you. Either way, after working through the mix of theory, code, examples, and case studies you’ll
find inside, you’ll be well on your way to understanding exactly how and why these advanced con-
cepts work—not just what they do to your document.
Vim is a fast and efficient text editor that will make you a faster and more efficient developer. It's available on almost every OS--if you master the techniques in this book, you'll never need another text editor. Practical Vim shows you 120 vim recipes so you can quickly learn the editor's core functionality and tackle your trickiest editing and writing tasks.
Vim, like its classic ancestor vi, is a serious tool for programmers, web developers, and sysadmins. No other text editor comes close to Vim for speed and efficiency; it runs on almost every system imaginable and supports most coding and markup languages.
Learn how to edit text the "Vim way:" complete a series of repetitive changes with The Dot Formula, using one keystroke to strike the target, followed by one keystroke to execute the change. Automate complex tasks by recording your keystrokes as a macro. Run the same command on a selection of lines, or a set of files.
Discover the "very magic" switch, which makes Vim's regular expression syntax more like Perl's. Build complex patterns by iterating on your search history. Search inside multiple files, then run Vim's substitute command on the result set for a project-wide search and replace. All without installing a single plugin!
You'll learn how to navigate text documents as fast as the eye moves--with only a few keystrokes. Jump from a method call to its definition with a single command. Use Vim's jumplist, so that you can always follow the breadcrumb trail back to the file you were working on before. Discover a multilingual spell-checker that does what it's told.
Practical Vim will show you new ways to work with Vim more efficiently, whether you're a beginner or an intermediate Vim user.
All this, without having to touch the mouse.
This product was previously referred to as an OUI (Organizationally Unique Identifier) and is still referred to as such in many standards. OUI is an IEEE Registration Authority (RA) specific term that is referred to in various standards and may be used to identify companies on the IEEE Public Listing. A MA-L assignment includes an OUI and the right to generate various extended identifiers based on that OUI. It is most often used to create IEEE 802-defined MAC addresses (EUI-48 and EUI-64).
