Quantum Physics I | Physics | MIT OpenCourseWare

Someday I’ll take this course at MIT online… Maybe when my kids are older.

This course covers the experimental basis of quantum physics. It introduces wave mechanics, Schrödinger’s equation in a single dimension, and Schrödinger’s equation in three dimensions.

It is the first course in the undergraduate Quantum Physics sequence, followed by 8.05 Quantum Physics II and 8.06 Quantum Physics III.

Programmer under oath admits computers rig elections Ohio 2004

After looking at the technical specs for Ohio 2004, there is no doubt in my mind that the election was stolen. The system was designed to facilitate it. At one point, the vote count in a particular county was going for Kerry, then a fail over occurred (for no reason that I could discern), and control of the vote count was handed off to a backup reporting server hosted in another state by a partisan Republican consulting firm who had been found guilty of electoral fraud previously. When the system came back up, Bush was suddenly winning.

No valid reason for the fail over was ever presented. The case died, because two years after the fact, what are they going to do? They got away with it.”

How to flush DNS cache Mac OS X Yosemite 10.10

DNS cache keeps an IP address stored in your computer. If you’re doing web development and you’ve moved your content to a new server sometimes you can’t reach it. The DNS entry needs to be changed.

In Mac OSX 10.10 Mavericks open up your terminal Application located in Applications/Utilities/Terminal

Mac OSX Terminal

One Simple Step to Clear DNS Cache on OS X Yosemite:

sudo discoveryutil udnsflushcaches

Now, ping the domain that was cached and the new IP should show up for you.

Set Default Browser in Mac OS X Yosemite – Chrome, Safari, Firefox

In previous versions of Mac OS X you defined the default browser inside of Safari. In Mac OS X you set the default browser inside of System Preferences -> General -> Default web browser.

Step 1: Open Up System Preferences and click on the “General” icon

Step 2: Select your default browser. I am switching from Safari to Google Chrome Canary

Now when you get a link in your email or any other place your new default browser will open up. Happy web surfin’.

View website domain before DNS A record is changed on Mac OS X Yosemite and Mavericks

You’re developing a site on a sub-domain or development server that is setup something like this, dev.YourDomain.com and you want to see if all the files and paths are correct. You’ve moved the site to a new server and IP and you want to check YourDomain.com there without disrupting the live site. Simply edit your /private/etc/hosts file on your Mac OS X box to reflect the new IP you want to test.

Real Live Site: YourDomain.com IP 2.2.2.2
Dev Site: dev.YourDomain.com IP 3.3.3.3
DNS Masked Site: YourDomain.com IP 4.4.4.4

Simply edit /private/etc/hosts and add the line

4.4.4.4 yourdomain.com www.yourdomain.com

Now when you ping yourdomain.com your system will return 4.4.4.4. Open up your browser and test your new site before making the DNS switch on the real DNS servers.

The hosts file is used to map hostnames to IP addresses. With the hosts file you can change the IP to which you resolve a certain domain name.

This is particularly useful when you wish to see how a website will look when hosted on a different server without having to wait for a DNS change to propagate, or avoiding any DNS changes at all.

Google Online Security Blog: This POODLE bites: exploiting the SSL 3.0 fallback

Say Goodbye to SSL 3.0

Today we are publishing details of a vulnerability in the design of SSL version 3.0. This vulnerability allows the plaintext of secure connections to be calculated by a network attacker. I discovered this issue in collaboration with Thai Duong and Krzysztof Kotowicz (also Googlers).
