Recently, I had a learning experience with cron jobs and acme.sh. acme.sh is an excellent tool that simplifies the management of Let's Encrypt TLS (SSL) certificates. It makes obtaining and renewing these essential security certificates for your web server easier. Recently, I moved my server from Linode to AWS, which was a new environment for me. Initially, everything appeared to be working correctly, and I assumed everything was running smoothly. However, I forgot to migrate the cron job that acme.sh uses to renew the certificate automatically. This oversight caused my Let's Encrypt certificates to expire, resulting in security warnings and potential disruptions for visitors to my website. Opps!

You can find the timezone in Linux using the command line. The easiest way to do this is to type the "timedatectl" command and look for the "timezone" line when using modern Linux distros with systemd. There are other commands and ways to temporarily switch to a new timezone for date calculations.

A new Arctic Report Card recap shows how the Arctic has transformed in just 20 years, warming about twice as fast as the global average and losing most of its oldest sea ice. It's also triggering cascading impacts from "Atlantification" to permafrost-driven "rusting rivers" and more destructive storms. Scientific American reports: The first Arctic Report Card was released by the National Oceanic and Atmospheric Administration in 2006. Since then the region has warmed twice as fast as the global average. About 95 percent of the oldest, thickest sea ice is gone -- "the sliver that remains is collected in an area north of Greenland. Even the central Arctic Ocean is becoming warmer and saltier, causing more ice melt and changing how much heat is released into the atmosphere in a way that affects weather patterns around the world. Those are just some of the stark changes 20 years have wrought. The findings were highlighted in the 2025 Arctic Report Card, released on Tuesday. The Arctic Ocean is undergoing what scientists are calling "Atlantification" -- a process where warm, salty water from the Atlantic flows north, changing how waters of different temperatures and densities are layered in the Arctic, disrupting ecosystems and altering how heat moves from the water to the air. [...] The Arctic is simply becoming wetter, with more precipitation falling as rain instead of snow. June snow cover over the entire Arctic is half of what it was 60 years ago, the report found. Permafrost also continues to thaw, releasing once trapped carbon into the atmosphere and disgorging iron and other elements that have turned rivers and streams orange. These "rusting rivers," found in more than 200 watersheds, are more acidic than normal and have elevated levels of toxic metals that endanger local ecosystems. And as the permafrost thaws, the tundra of the Arctic biome is shrinking, and the boreal forest biome is creeping northward, disrupting ecosystems.

An anonymous reader quotes a report from the Wall Street Journal: The alleged perpetrator had improper access to virtually every South Korean adult's personal information: names, phone numbers and even the keycode to enter residential buildings. It was one of the biggest data breaches of recent years and it has sent the company it targeted -- Coupang, South Korea's equivalent of Amazon -- reeling, generating lawsuits, government investigation and calls to toughen penalties against such leaks. The leak went undetected for nearly five months, hitting Coupang's radar on Nov. 18 only after a customer flagged suspicious activity. At first, Coupang, which was founded by a Korean-American entrepreneur, said it had experienced a data "exposure" affecting roughly 4,500 customer accounts. But within days, the e-commerce firm revised the figure: The leak exposed up to roughly 34 million user accounts in South Korea -- a sum representing more than 90% of the country's working-age population. Coupang started calling the incident a "leak" after Korean regulators took issue with the company's prior word choice. "The Whole Nation Is a Victim," read one local news headline. An investigation has found that the alleged perpetrator had once worked in South Korea as a software developer for authentication systems at Coupang, which is known for its blockbuster U.S. initial public offering a few years ago. The suspected leaker is believed to be a Chinese national who has moved back to China and is now on the lam, South Korean officials say. They haven't named the person. Even after leaving the firm roughly a year ago, the suspect secretly held on to an internal authentication key that granted him unfettered access to the personal information of Coupang users, South Korean authorities and lawmakers say. The infiltration, using overseas servers, started on June 24. By using the login credentials, the suspect was able to appear as if he were still a Coupang employee when accessing the company's systems.
