Chrome Developer Tools: Overview - Google Chrome Developer Tools - Google Code

Chrome Developer Tools: Overview - Google Chrome Developer Tools - Google Code: "The Developer Tools, bundled and available in Chrome, allows web developers and programmers deep access into the internals of the browser and their web application. The Developer Tools are heavily based on the WebKit Web Inspector, a part of the open source WebKit project. This overview of the Developer Tools points out its most popular and useful features. The target audience are web developers who don't know of, or have not yet investigated, the Developer Tools. However, we are sure that even if you are an experienced web developer, you will pick up a tip or two."

Introduction to Autofs in Mac OS X

Introduction to Autofs in Mac OS X: "OS X auto_master and auto_home

The /etc/auto_master file controls the auto-mounted Network File System (NFS) file systems. If you are going to mount NFS volumes from a Linux server, there is one gotcha that I covered in an earlier blog post.

The auto_master defines all "maps" which are collections of automounts related by mount point and organized in one file (or directory service entry). Here is what the default file looks like on my Mac:

#
# Automounter master map
#
+auto_master # Use directory service
/net -hosts -nobrowse,nosuid
/home auto_home -nobrowse
/Network/Servers -fstab
/- -static"

Note To Self: Restart autofs – The Adventures of Systems Boy!

Note To Self: Restart autofs – The Adventures of Systems Boy!: "To restart autofs on Mac, do this:

sudo killall -HUP autofsd
To be additionally thorough, though this should not be necessary, you could also restart automount, which now looks slightly different (note the “d”, which is new):

sudo killall -HUP automountd"

Partial derivative - Wikipedia, the free encyclopedia

Partial derivative - Wikipedia, the free encyclopedia: "In mathematics, a partial derivative of a function of several variables is its derivative with respect to one of those variables, with the others held constant (as opposed to the total derivative, in which all variables are allowed to vary). Partial derivatives are used in vector calculus and differential geometry."

Dot product - Wikipedia, the free encyclopedia

Dot product - Wikipedia, the free encyclopedia: "In mathematics, the dot product or scalar product is an algebraic operation that takes two equal-length sequences of numbers (usually coordinate vectors) and returns a single number obtained by multiplying corresponding entries and then summing those products. The name "dot product" is derived from the centered dot "  " that is often used to designate this operation; the alternative name "scalar product" emphasizes the scalar (rather than vector) nature of the result."

Universal quantification - Wikipedia, the free encyclopedia

Universal quantification - Wikipedia, the free encyclopedia: "In predicate logic, universal quantification formalizes the notion that something (a logical predicate) is true for everything, or every relevant thing. The resulting statement is a universally quantified statement, and we have universally quantified over the predicate. In symbolic logic, the universal quantifier (typically , U+2200 ∀ , a turned A) is the symbol used to denote universal quantification, and is often informally read as "given any" or "for all". Universal quantification is distinct from existential quantification ("there exists"), which asserts that the property or relation holds for at least one member of the domain."
