- Cocos2D Tutorial – Dynamically Coloring Sprites [Brandon Trebitowski, brandontreb.com] Have you ever seen a game (such as Tiny Tower) that contains similar sprites that only vary by certain attributes (coloring, shading, accessories, etc…)? I would often wonder how long it would take the artists to create each permutation of these sprites. After discovering that you can call a method on a CCSprite called setColor, I realized how most of this customization is done in code.
- Muddying the Budget Waters With Social Security Many people misunderstand how the program operates. Payroll taxes stream into the trust fund that is used to pay current retirees’ benefits. When there is a surplus, that money is invested in a special type of Treasury bond that pays interest to the trust fund. At the end of last year, the trust fund had about $2.6 trillion. And though last year was the first year since 1983 that the fund paid out more than it received in tax revenue, it still continued to grow because of the interest accrued — and it is estimated to continue to grow through 2022.
Since the money in the trust fund is held in Treasury securities, taxes collected are essentially being lent to the federal government to pay for whatever it wants (and this allows the government to borrow less from the public).
- The Cult of Centricism We have a crisis in which the right is making insane demands, while the president and Democrats in Congress are bending over backward to be accommodating — offering plans that are all spending cuts and no taxes, plans that are far to the right of public opinion.
So what do most news reports say? They portray it as a situation in which both sides are equally partisan, equally intransigent — because news reports always do that. And we have influential pundits calling out for a new centrist party, a new centrist president, to get us away from the evils of partisanship.
The reality, of course, is that we already have a centrist president — actually a moderate conservative president.

- Make a backup copy of the MacBook Air USB Software Reinstall Drive | TUAW – The Unofficial Apple Weblog Since it doesn't come with an optical drive, giving MacBook Air buyers a DVD of the operating system wouldn't be very helpful. That's why Apple's lightest laptop comes with the USB Software Reinstall Drive — a very small white USB drive. Sometimes USB flash drives are referred to as "Thumb Drives," but this one is more like the size of a baby's finger.
