Yesterday, GraphSketch passed over 30,000 graphs rendered. That’s quite a few. Thanks to everyone for making it so popular.
It also seemed like a good time to release something I’ve been working on smoothing out for the past few weeks:
Yep, you can now graph parametric equations. Just head over to http://graphsketch.com/parametric (or click the “Parametric”mode just above the equations on the main GraphSketch page).
To keep things simple, you can only graph three parametric sets of equations at the same time. You can choose the range for t, and it defaults to a reasonable -10 to 10.
Also, while I was updating the website, I made the text a bit smaller (about the difference of going from a 12pt font to a 10pt font) and added a (hopefully unobtrusive) section pointing out the availability of posters, should anyone be interested. Polar graphing should come soon, hopefully, but it is somewhat possible using parametric equations by setting x=r*cos(t) and y=r*sin(t), too.

A number of you who know me in real life have probably seen a number of my posters. Three of them currently adorn my dorm room. I had been offering them to friends I knew, but not to everyone, because I hadn’t gotten around to it. But that has changed now, with posters.lardbucket.org.
The website itself is (purposely) a bit sparse, but it will let you browse the four existing posters, and grab one for yourself from Zazzle at fairly reasonable prices. (I really only make a few dollars from each one, depending on size.) Other than taking a while to ship, Zazzle’s processing has been fairly good, and the three large prints I have from them are reasonably high quality, even on their “basic poster” paper.
Each of the posters on posters.lardbucket.org was created by me, using a reasonably high-powered computer to do the rendering. Each of the posters is a mathematically-defined rendering, and could theoretically be rendered at any size and not lose any detail. Therefore, the large posters are still high quality images.
So, if you’d like to get a neat-looking poster and send a few dollars my way at the same time, have a look at posters.lardbucket.org.
Thanks,

In under three weeks since it was launched, GraphSketch has now been used to create (over) 10,000 graphs. It also has had over 3,500 visitors, coming from every continent except Antarctica, though many visitors haven’t graphed anything (and many visitors have graphed far more than average). Work on new features (parametric and polar graphing, among others) will likely resume after school is over, as I still have three finals remaining, and am now off to continue studying for a math final.
At any rate, thanks to everyone who has promoted GraphSketch in one place or another for making it so successful.

P.S. If you have any suggestions for GraphSketch itself, the original post on it is still probably the best place to leave them, as I’ll check back there for ideas when I’m working on it. Thanks!
This time I don’t have a photo or anything, but they did mention the project I’m working on that’s available here, called PeopleFinder. The project attempts to get data from many different websites and combine it into one searchable database. If you can’t find me in the Correspondent, I’m on the front page, bottom half, left column, toward the bottom.
Unfortunately, they implied that I created the website (from scratch), which I most certainly did not. The site and interface itself were entirely done by others. I “simply” found ways to import a few thousand records from other websites and uploaded information for other people.
More news too, but I can’t much talk about that right now. I’m sure I’ll have something else for the blog later as well.
I appear on the top of the front page on tomorrow’s Correspondent! (The Correspondent is our school paper.) The story is about my schedule website, which is still available at http://schedule.lardbucket.org. I can only say that it mentioned Tommy and I, and that it appeared to be all positive. If I can post more later, I will.
Andy
