For other uses, see cache (disambiguation) or caché.

In computer science, a cache (pronounced , like the English word cash) is a collection of data duplicating original values stored elsewhere or computed earlier, where the original data is expensive (usually in terms of access time) to fetch or compute relative to reading the cache. Once the data is stored in the cache, future use can be made by accessing the cached copy rather than refetching or recomputing the original data, so that the average access time is lower.

Caches have proven extremely effective in many areas of computing because access patterns in typical computer applications have locality of reference. There are several sorts of locality, but we mainly mean that the same data are often used several times, with accesses that are close together in time, or that data near to each other are accessed close together in time.

Some CrunchBase API Stats and Apps
Henry Work Sat, 30 Aug 2008 00:58:44 -0000
Six weeks ago we launched an API for our technology database, CrunchBase. The idea was to give away lots of clean, structured data about the companies we cover, data that could be used to build new services and improve upon existing ones. Since then we've seen a number of impressive things built on top of the API. And the traffic has started to add up: between July 15th and August 15th we fulfilled nearly 800,000 API requests, compared to ~1.3m page views for the website itself. We now have over 15 projects hooked up to CrunchBase with many others on the way. Developers interested in using CrunchBase data for their own projects should check out the API documentation. Today we wanted to highlight a few of the more sophisticated product integrations to date.
The Mysterious Ways Of Apple’s Top Apps List
Jason Kincaid Sat, 30 Aug 2008 00:24:27 -0000
Apple's App Store is quickly becoming a hotbed for elite developers looking to capitalize on the store's easy distribution model and huge exposure opportunities. Since the store's launch less than two months ago, we've seen reports of apps reaching massive user bases and and collecting millions of dollars. But while the store has seen its share of its successes, it also has its flaws - most notably in the way it exposes users to apps in the first place.

A rumor is circulating that the iPhone may be finally making its way to China. The original source of the rumor is China Communications, which has cited a China Mobile insider as its source. According to the source, China Mobile will be offering the iPhone at a heavily subsidized discount in order to court the massive Chinese population, many of whom would have trouble affording an unsubsidized phone.
Ok Someone At Google Is Just Messing With My Head
Michael Arrington Fri, 29 Aug 2008 20:29:48 -0000
A couple of days ago I posted an email that I received from Google letting me know that I wouldn't be able to attend a Google/Vanity Fair party at the Democratic National Convention that I never knew about and didn't ask to go to. Other people who also didn't know about the party received the same email. Today I get another email, also from Google, inviting me to attend the mirror party at the Republican Convention in Minneapolis next Thursday. Is this for real or are they just going to cancel on me again? Get out of my head, Google. I will not be fooled into RSVPing only to have you kick me out later. :-) Email is below:
