- A Short On How The Wayback Machine Stores More Pages Than Stars In The Milky Way
Playback is accomplished by binary searching a 2-level index of pointers into the WARC data. The second level of this index is a 20TB compressed sorted list of (url, date, pointer) tuples called CDX records. The first level fits in core, and is a 13GB sorted list of every 3000th entry in the CDX index, with a pointer to larger CDX block.
Index lookup works by binary searching the first level list stored in core, then HTTP range-request loading the appropriate second-level blocks from the CDX index. Finally, web page data is loaded by range-requesting WARC data pointed to by the CDX records. Before final output, link re-writing and other transforms are applied to make playback work correctly in the browser.

I wanted to point out that there's a difference between whining about how your government does something, and building a secure ecosystem.

- Microsoft’s Most Clever Critic Is Now Building Its New Empire
When Alchin offered him the job, Russinovich didn’t take it. But after several more years spent running his Sysinternals site–where he published a steady stream of exposés that, in his words, “pissed off” Microsoft and other tech outfits–he did join the software giant. The company made him a Microsoft Technical Fellow–one of the highest honors it can bestow–and today, he’s one of the principal architects of Microsoft Azure, the cloud computing service that’s leading the company’s push into the modern world.
