Map matrix element to string phpmyadmin not working due to missing extensions I am about to use phpmyadmin on Ubuntu 16.04.

Consider the dihedral group  $$D_{2n}= \langle a,b \mid a^n = 1 = b^2, b^{-1}ab = a^{-1}\rangle$$  How can I show that $|D_{2n}| = 2n$?   I'm trying to show that we can write every element in the form  $$x = a^i b^j$$ where $i= 0, 1, \dots, n-1$; $b = 0,1$.   I managed to show existence, and it is clear that there are $2n$ such elements, so if I can show that every choice of $i,j$ gives a distinct element, I'll be done.  Any ideas? Typing the ZIP code doesn't yield the company page How do I get timestamp from e.g. 22-09-2008? Is there a way to load my own custom CSS or Javascript while using a browser?  When I'm accessing a website or developing a website I want to load my own custom scripts from my computer. I know this can be done by Firebug or Chrome's developer toolbar, but after you refresh your browser your changes will be cleared too. This is exactly what I'm looking for adding CSS and Javascript, but I wish it has an option where you temporarily save your changes locally. Or it has an option to load external CSS or JS files.   Purpose:   When I'm developing the frontend, sometimes it's convenient for me using Chrome's developer toolbar or Firefox's Firebug to change or tweak CSS properties because I can then see the changes in real time without refreshing. One problem I see is that every time I refresh my browser, my changes also get reset. Now I wish there were an option where I could save my changes locally or load my own external .css file or .js file. I want to customize how some websites look when viewed locally, e.g., accessing a blog that has too many ads. I want to apply CSS properties to hide the junk.   Browsers I use often:   Google Chrome (for development: Built-in Dev Toolbar) Mozilla Firefox (for development: Firebug) I had read a story / article about artificial intelligence, I think it was last year (2012) but I'm not sure when it was published. It was on an online blog for an institute I believe. I am telling the story in quotes, just to demarcate where the story begins and ends.  In the story, a scientist is trying to build a perfect AI system which can respond to human interaction perfectly. Apparently the only way this is possible is to make the computer believe that it is human. He creates what he believes is the solution, and asks a friend to volunteer for a test, and the friend agrees. For the test the friend is supposed to step into a tank full of a liquid. As soon as he enters the tank, he is told, he will lose all his sensations - no vision, no hearing etc. After entering the tank, he talks to the computer and responds, and isn't able to recognise that he is in fact talking to a computer. After some time (days? Don't remember) has passed, he begins to worry - why is he still trapped in the tank? At this point the scientist tells him that he is in fact the computer he has made, the memory that he has of the human life till the time he enters the tank has been implanted in the machine, so he thinks he is human. He is not in a tank, he is a computer, and that is why he can't see or feel anything. The story ends here.  It is told from the perspective of the computer itself, but since it is an article in a science blog / forum for a technical college, it feels like you're reading an actual experiment when you start reading. It was a rather nice surprise ending to the story in my opinion. I just can not seem to be able to locate the article / story anywhere. Can somebody who might have read this help me? Even just pointing me in the direction of the site it is hosted on would be great.

Short story: rocket fuel which oxidizes iron destroys life on earth I'm looking for the title of a short science fiction story, probably published in a Hugo winner collection 30 years ago. In the story, scientists have developed an extremely efficient rocket fuel that has one dangerous side-effect: it oxidizes iron. A man takes off in a rocket powered by this fuel but returns to find the earth completely devoid of life. His subsequent investigation reveals that a single drop of the fuel began a domino effect, as the substance oxidized all iron it came into contact with. In the end, the man is dying.  He drags himself to the ocean, believing that if he can get his living cells into the water they will restart the primordial soup. How can I benchmark my HDD?
