The Rise and Fall of Bitcoin

In 2008, an enigmatic person or group named Satoshi Nakamoto introduced the concept of bitcoin, a digital currency, in a research paper. Bitcoin resolved the double-spending problem and eliminated the need for a central clearinghouse by using a public ledger called the "block chain." Early adopters embraced bitcoin, and it gained popularity outside the cryptography community. However, Nakamoto's true identity remains a mystery, and he disappeared after the currency's initial launch, leaving the project to grow independently. Bitcoin's decentralized nature made it immune to government and banking oversight, appealing to those seeking a secure and independent form of currency.

This article by Benjamin Wallace on Wired takes a pretty deep dive into the story of Bitcoin, its origin, timeline and how it works.

Google shuts down Google Directory

Google has shut down the human curated web directory named Google Directory last week, on July 20th.

The web directory - which was hosted at http://directory.google.com - was organized into 16 broad categories and further subcategories, and was based on DMOZ, an open-source project also known as the Open Directory Project (ODP).

During the early days of the World Wide Web, web directories were a preferred way to discover and find content on the web but with the advent of crawler-based search engines, the relevance of web directories have diminished. Below is a screenshot (for remembrance) as the page was on July 17, 2011 - also archived here.

The rival project Yahoo! Directory is, however, still up and running at http://dir.yahoo.com/.

Update 2014-12-31: Yahoo! has also shut down its web directory which I have logged here.
