Linus is the person with the most commits in the source tree in 2021

Recently, Phoronix, a Linux hardware review site, released a report on Git development statistics for 2021. According to the report, as of December 31, 2021, when GitStats was running on the Linux kernel source tree, the repository had 1,060,172 commits from around 243,000 different authors. The source tree currently consists of 32.2 million lines involving 74,300 files. The Linux kernel line count continues to grow at a fairly steady rate and into the mainline as new features continue to be developed and hardware support expands.

FTC Warns of Legal Action Against Organizations That Fail to Patch Log4j Vulnerabilities

The U.S. Federal Trade Commission (FTC) has warned that U.S. organizations that fail to protect customer data from a Log4Shell vulnerability could face legal consequences. Log4Shell is the widely used name for a zero-day vulnerability in the Log4j Java logging library. A critical vulnerability, first discovered in December, is being exploited by a growing number of attackers, posing a "serious risk" to millions of consumer products, the FTC warned. The open letter urges organizations to address the loophole to reduce the potential for harm to consumers and avoid the risk of legal action. "When discovered and exploited, these vulnerabilities can result in the loss or disclosure of personal information, financial loss and other irreversible harm," the agency said. "Including the Federal Trade Commission Act and Financial Services Modernization Laws, including the Act, require reasonable steps to address known software vulnerabilities. Companies that rely on Log4j and their suppliers must act now to reduce the potential for harm to consumers and avoid legal action by the FTC. One point is crucial."
