10 Images That Changed the Course of Science (And One That Is About To) To understand this you need to understand quantum theory a little better. It's not that orbitals invalidated the stick-and-ball models of chemistry at all. If anything orbitals explained to us why the bonds are arranged as they are in stick-and-ball models. Prior to quantum theory, we only knew the geometry and patterns of those bonds by experiment. Prior to quantum theory, chemistry had no general theory to explain why atomic bonds are shaped as experiment revealed them to be. Stick-and-ball models are perfectly fine to use to tell us the shapes of molecules. As to what's being shown in the image, what you are seeing is are the places where electrons are most likely to be found. I like to think of the balls as cartoon beehives. They pretty much signify, "Bees are around here"; now, how many bees are in the hive and not taking a little trip flying around nearby? I suppose that works too.
Setup Unmanaged VPS 4 Linux Noobs! - vpsBible WORDOID - Creative Naming Service Augmented Reality with #Processing - Tutorial by Amnon Owed All of the visuals in the above video were created using NyArtoolkit for Processing. NyARToolkit is an augmented reality toolkit built with 100% pure Java. It is derived from ARToolkit-2.72.1. Like Processing itself it’s open source and free! All right so let’s start with the general setup. 1. 2. 3. 4. All right, time to recap. Example 1: Basic The first example is basic, but holds all of the important techniques that are necessary for more advanced uses of the NyArtoolkit. If you input the following image (place it in the sketch’s data subdirectory)… …into the first code example, you should end up with something like this… Example 2: Dynamic Time to get a little more dynamic. Example 3: OOP The third example serves two purposes. Main Sketch ARObject Troubleshooting & General Tips If you get an “Exception occurred at Multimarker.Multimarker” you probably haven’t changed the camPara String.
Django with Mysql and Apache on EC2 — The Usware Blog - Django Web Development By : Shabda Raaj What is EC2 Unless you have been living on Mars these last few years, you are sure to have heard of EC2. How does EC2 work? A EC2 machine is nothing but a bare machine. The prerequisites You need to have an AWS account with EC2 enabled. Give ElasticFox your EC2 credentials. I started the AMI with AMI id ami-f27c999b. After you start your ami, right click in ElasticFox on your instance and get its Public DNS. My public dns was ec2-75-101-203-97.compute-1.amazonaws.com, my private key is stored in a file called id-django. shabda@shabda-laptop:~$ ssh -i id-django root@ec2-75-101-203-97.compute-1.amazonaws.com..........root@domU-12-31-39-02-BC-E1:~# Fine, we are in our brand new EC2 server now! Ok, so we created a new user and gave the new user shabda sudo rights. shabda@shabda-laptop:~$ ssh shabda@ec2-75-101-203-97.compute-1.amazonaws.comshabda@ec2-75-101-203-97.compute-1.amazonaws.com's password:...shabda@domU-12-31-39-02-BC-E1:~$ Ok we are logged in as shabda.

The Year That Was Tom Scocca, Managing Editor of Deadspin, Slate Columnist, and Author of Beijing Welcomes You In this chain-reaction year—disaster, war, revolution, and death chasing one another around the globe—the pepper-spray assault at Cal-Davis was nowhere near the biggest event. Instead, it was small enough to be intelligible. This was an American college campus where a thug cop, in doomsday black armor, hosed down a row of seated students with a chemical weapon. Sohaib Athar, @ReallyVirtual, Who Inadvertently Live-Tweeted the bin Laden Raid The importance of an event is, of course, subjective, so while the Occupy movement may be the most important event of the year for some, the Arab Spring would be more important for others.

Philip Roche » Simple Django install on Amazon EC2 I set up an amazon ec2 instance this weekend and as I knew I’d bedoing it again I noted the steps performed. Hopefully they’ll be of use to someone. Firstly you need to set up an EC2 account. I’d also recommend downloading () which makes it easier to manages instances, volumes andelastic IPs. Also install the so you can start and stop instances etc. The following guide is what I did to set up an Ubuntu 9.10 instance with EBS volume attached and a basic django install running. References to 79.125.24.49 are to my elastic IP address that I set up using Elasticfox so it will be different for you. Seting up Ubuntu 9.10 django install on EC2
Sotades Sotades (Greek: Σωτάδης; 3rd century BC) was an Ancient Greek poet. Sotades was born in Maroneia, either the one in Thrace, or in Crete. He was the chief representative of the writers of obscene and even pederastic satirical poems, called Kinaidoi, composed in the Ionic dialect and in the "sotadic" metre named after him. The sotadic metre or sotadic verse, which has been classified by ancient and modern scholars as a form of ionic metre, is one that reads backwards and forwards the same, as “llewd did I live, and evil I did dwell.” These verses have also been called palindromic. Sotades lived in Alexandria during the reign of Ptolemy II Philadelphus (285-246 BC). Only a few genuine fragments of Sotades have been preserved; those in Stobaeus are generally considered spurious. Sotades was also the author of some of the first recorded palindromes, and many credit him with the invention of that particular genre of composition.
