We have constructed a fully functional, fully integrated radio receiver, orders-of-magnitude smaller than any previous radio, from a single carbon nanotube. The single nanotube serves, at once, as all major components of a radio: antenna, tuner, amplifier, and demodulator. Moreover, the antenna and tuner are implemented in a radically different manner than traditional radios, receiving signals via high frequency mechanical vibrations of the nanotube rather than through traditional electrical means. We have already used the nanotube radio to receive and play music from FM radio transmissions such as Layla by Eric Clapton (Derek and the Dominos) and the Beach Boy's Good Vibrations. The nanotube radio's extremely small size could enable radical new applications such as radio controlled devices small enough to exist in the human bloodstream, or simply smaller, cheaper, and more efficient wireless devices such as cellular phones.

This is the first in a series of online tutorial lessons designed to teach you how to program using the Python scripting language. There is something for just about everyone here. Beginners start at the beginning, and experienced programmers jump in further on. You simply need to enter the series of lessons at the point that best fits your prior programming knowledge.

So here are 25 Web 2.0 applications (mostly free) that should help you on your quest as a student or professor in being productive.

This utility reads all information from the history file on your computer, and displays the list of all URLs that you have visited in the last few days. It also allows you to select one or more URL addresses, and then remove them from the history file or save them into text, HTML or XML file. In addition, you are allowed to view the visited URL list of other user profiles on your computer, and even access the visited URL list on a remote computer, as long as you have permission to access the history folder.

"Today we look at how data-tracking companies are monitoring your online behavior. While news reports have focused on the National Security Administration and its efforts to monitor people's phone calls and online activities, private companies you have probably never heard of are also tracking what you are doing, just about everywhere you leave a digital footprint."

"Now that you we have used all the right semantics you might want to change the width of each column - as of right now, each column is 33% wide. Let's say we want the first column to be 40% of the table and the two remaning columns to be 30% (as 40% + 30% +30% = 100%). In order to do this, we use the element. This element is to be placed between the tag and the tag and we use the style attribute to define the width of the columns. The element is a self-closing element and you need one for every columns of you table. Let's have an example:"

"You could also use the csv module import csv myfileobj = open("myfiletab.txt","read") csv_read = csv.reader(myfileobj,dialect=csv.excel_tab) myval1 = [] myval2 = [] myval3 = [] for line in csv_read: # filter header and stuff using some criterion if len(line) = 3: myval1.append(line[0]) myval2.append(line[1]) myval3.append(line[2])"

"Course notes This course is part of the Scientific Computing series, and as such many of the examples chosen are of most relevance to scientific computing. The course notes (in various forms) are available here. The files used during the course are available here. This course is aimed at those who already know how to program in another high level programming language (such as C/C++, Fortran, Java, Perl or Visual Basic) and who now wish to learn Python. (Those with little or no prior programming experience should try the "Python: Introduction for Absolute Beginners" course instead.) The aim of this course is to provide sufficient familiarity with Python that attendees can attend any of our more advanced Python courses and easily follow any of the widely available Python tutorials on the more complex aspects of the language."

An Inbox, a huge Archive, starred mail, chats, Spam and all kinds of labels: ways to view mail abound in Gmail. Where, though, is the unread mail - all the unread mail, be it in the archive or the Inbox or anywhere else, and only the unread mail? Fortunately, "unread" is an attribute that messages in Gmail carry like a label. This means you can search - and find - these unread emails easily.
