How to add cron job entry for acme.sh
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!

How do I find out my timezone in Linux?
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.

5K Gaming Is Too Hard, Even for an RTX 5090D
Asus has been showcasing its new 5K 27-inch ROG Strix 27 Pro gaming monitor running at 5,120 x 2,880 resolution and up to 180Hz, but even Nvidia's flagship RTX 5090 struggles to deliver smooth frame rates at this demanding pixel count. In testing conducted by Asus, the RTX 5090D -- a Chinese-exclusive variant with weaker AI performance -- achieved just 51 frames per second in a Cyberpunk 2077 benchmark at ultra ray traced settings. The test system ran an AMD Ryzen 9950X3D processor, had DLSS set to balanced, and kept frame generation disabled. The same configuration running at 4K managed 77 fps, around 50% higher.
The underlying math is simple: 5K resolution requires rendering 78% more pixels than 4K. That 218 PPI pixel density delivers impressive sharpness up close, but Asus chose an IPS panel over OLED technology to reach it, trading away deeper black levels and faster response times. Asus appears to be positioning the monitor as a dual-mode display -- 5K for productivity and video, 1440p at up to 330Hz for gaming. Early Chinese listings have it priced at the equivalent of $800, roughly what you'd pay for a larger 4K OLED panel.

Ryanair Fined $301M Over 'Abusive Strategy' To Limit Ticket Sales By Online Travel Agencies
Speaking of Italy's competition authority , it has fined Ryanair $301 million for abusing its dominant market position to limit sales of tickets by online travel agents. The Guardian: The authority said Europe's largest airline had "implemented an abusive strategy to hinder travel agencies" via an "elaborate strategy" of technical obstacles for agents and passengers to make it difficult for online travel agents to sell Ryanair tickets and instead force sales through its own website.
The fine related to Ryanair's conduct between April 2023 and at least until April 2025, the authority said on Tuesday. It said Ryanair had prevented online travel agents from selling tickets on its flights in combination with other airlines and services, weakening competition. Ryanair said it would immediately appeal against the "legally flawed" ruling.

Apple and Google Asking Some Employees With H-1B Visas To Avoid International Travel
Tech giants Google and Apple are asking some employees with H-1B visas to reconsider international travel, as their legal teams warned that visa processing delays could keep employees abroad for months, according to Business Insider. From a report: Law firms representing the tech giants sent memos advising staff who require visa stamps for reentry to stay in the U.S., warning that international travel could entangle them in visa screening delays following the introduction of a new social media screening requirement, according to the news agency. The policy subjects H-1B workers and their dependents to reviews of their social media histories.
"Please be aware that some US Embassies and Consulates are experiencing significant visa stamping appointment delays, currently reported as up to 12 months," BAL Immigration Law, which represents Google, said in a memo obtained by Business Insider. The law firm said the delays were affecting H-1B, H-4, F, J and M visas.
