(4) Dump the teacher's union. Give teachers the authority to make the changes needed in education.

Credit Ronald Reagan with the popularity of such schizophrenic reasoning. This one suggests we dump the teachers union and give teachers the authority to make changes. I suppose the teachers will decertify the union and then get together and form an "organization"? Or maybe you're just naive in thinking individual teachers have the power to do anything at all outside of the union agreement. Public school administrators are typically adversarial towards teachers.

I don't know if this is comparable, but I use Metapost for drawing graphs and diagrams. Actually, I draw diagrams long-hand on graph paper, with coordinates labeled, and code it up in Metapost. Even my 3D diagrams look really nice. The EPS output is scalable and can be included directly in TeX (or LaTeX) documents.

People tell me drawing diagrams long-hand first is too much trouble, but it really is the "secret sauce" for me. Also, Metapost is incredibly powerful once you dig in. I think it is ideal for technical drawings. The language is simple and powerful.

The best advice you will ever get: Starting today, spend every single day studying for your PhD exams. Next summer, after you finish the exams, you can hike the Appalachians. Your professors will consider you a genius, or at worst hard-working, and they will write you great recommendations. Don't waste time while you're in graduate school.

The subsidized handset business model is popular with typical US customers because customers do not realize that they are actually paying full price for their handset through what is essentially an installment plan.

The high retail prices of cell phones are fiction. An iPhone for $999???: http://www.newegg.com/Product/Product.aspx?Item=N82E16875100060 Granted, this is Apple. But there have always been shitty phones with "retail prices" of $500-$800.

Dead? No excuse for laying off work.
