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.

Linux updates don't scare me anymore thanks to this immutable distro (and it's easy to use)  ZDNET

A federal court in California has ruled that YouTube creators who use stream-ripping tools to download clips for reaction and commentary videos may face liability under the DMCA's anti-circumvention provisions -- a decision that could reshape how one of the platform's most popular content genres operates. U.S. Magistrate Judge Virginia K. DeMarchi of the Northern District of California denied a motion to dismiss in Cordova v. Huneault, a creator-versus-creator dispute, finding that YouTube's "rolling cipher" technology qualifies as an access control measure under section 1201(a) even though the underlying videos are freely viewable by the public. The distinction matters because it separates the act of watching a video from the act of downloading it. The defense had argued that no ripping tools were actually used and that screen recording could account for the copied footage. Judge DeMarchi allowed the claim to proceed to discovery regardless, noting that the plaintiff had adequately pled the circumvention allegation. The ruling opens a legal avenue beyond standard copyright infringement for creators who want to go after rivals. Reaction channels have long leaned on fair use as a blanket defense, but plaintiff's attorney Randall S. Newman told TorrentFreak that circumventing copy protections under section 1201 is a separate violation unaffected by any fair use finding.

NASA Administrator Jared Isaacman has announced that astronauts on the upcoming Crew-12 and Artemis II missions will be allowed to carry iPhones and other modern smartphones into orbit and to the Moon -- a reversal of long-standing agency rules that had left crews relying on a 2016 Nikon DSLR and decade-old GoPros for the historic lunar flyby. Isaacman framed the move as part of a broader push to challenge what he called bloated qualification requirements, where hardware approvals get mired in radiation characterization, battery thermal tests, outgassing reviews and vibration testing. "That operational urgency will serve NASA well as we pursue the highest-value science and research in orbit and on the lunar surface," he wrote.

2026 will be the year of gaming on Linux  XDA

Elon Musk told podcast host Dwarkesh Patel and Stripe co-founder John Collison that space will become the most economically compelling location for AI data centers in less than 36 months, a prediction rooted not in some exotic technical breakthrough but in the basic math of electricity supply: chip output is growing exponentially, and electrical output outside China is essentially flat. Solar panels in orbit generate roughly five times the power they do on the ground because there is no day-night cycle, no cloud cover, no atmospheric loss, and no atmosphere-related energy reduction. The system economics are even more favorable because space-based operations eliminate the need for batteries entirely, making the effective cost roughly 10 times cheaper than terrestrial solar, Musk said. The terrestrial bottleneck is already real. Musk said powering 330,000 Nvidia GB300 chips -- once you account for networking hardware, storage, peak cooling on the hottest day of the year, and reserve margin for generator servicing -- requires roughly a gigawatt at the generation level. Gas turbines are sold out through 2030, and the limiting factor is the casting of turbine vanes and blades, a process handled by just three companies worldwide. Five years from now, Musk predicted, SpaceX will launch and operate more AI compute annually than the cumulative total on Earth, expecting at least a few hundred gigawatts per year in space. Patel estimated that 100 gigawatts alone would require on the order of 10,000 Starship launches per year, a figure Musk affirmed. SpaceX is gearing up for 10,000 launches a year, Musk said, and possibly 20,000 to 30,000.

New limited-time offers. Delta Airlines American Express cards offer various special perks like free checked bags, priority boarding, and the ability to earn Delta SkyMiles with card purchases. As you can only get the welcome offers once per specific card name per person per lifetime (a Gold and Platinum card are considered different), I recommend waiting until a limited-time offer to maximize your benefit. I recommend the Gold card as the first sweet spot for many casual travelers, as it currently offers a $900 potential first-year value with no annual fee the first year, along with a free checked bag benefit. Details:

Delta SkyMiles® Gold American Express Card

• Up to 90,000 Bonus Skymiles. 70,000 bonus miles after you spend $3,000 or more in purchases with your new Card within the first 6 months of Card Membership and an additional 20,000 bonus miles after you make an additional $2,000 in purchases within the first 6 months, starting from the date your account is opened. Offer Ends 4/1/2026.
• $200 Delta Flight Credit. Get a $200 Delta Flight credit to use toward future Delta travel after $10,000 in purchases on your card within a calendar year.
• $100 Delta Stays Credit. Get up to $100 back annually as a statement credit after using your Delta SkyMiles(R) Gold American Express Card to book prepaid hotels or vacation rentals through Delta Stays on delta.com.
• First checked bag free (worth $70 roundtrip, per person) on Delta flights. This perk is worth up to $280 per round trip for a family of four ($35 each way, per person).
• 15% off discount on Award Travel booked through delta.com and the Fly Delta app. Applies to Delta flights only, not applicable to partner-operated flights or taxes and fees.
• Zone 5 Priority Boarding.
• 2X miles at Delta purchases, at U.S. Supermarkets and at restaurants worldwide, including takeout and delivery in the U.S. Earn 1 miles per dollar spent on all other eligible purchases.
• Simplified Pay with Miles option. Take up to $50 off the cost of your flight for every 5,000 miles you redeem with Pay with Miles when you book on delta.com.
• 20% back on eligible Delta in-flight purchases with this card in the form of a statement credit .
• No Foreign Transaction Fees.
• $0 introductory Annual Fee for the first year, then $150.

90,000 Skymiles is worth at least $900 in Delta airfare. Delta offers a minimum value out of your Skymiles via the “Pay with Miles” option. For example, that means 50,000 Skymiles can reduce the price of your Delta ticket(s) by $500 at the very least. (5,000 mile = $50 minimum redemption.) You can still search and book traditional award tickets and possibly get better value.

Delta SkyMiles® Platinum American Express Card

• Limited-time offer: Up to 100,000 Bonus Miles 80,000 bonus miles after you spend $4,000 or more in purchases with your new Card within the first 6 months of Card Membership and an additional 20,000 bonus miles after you make an additional $2,000 in purchases within the first 6 months, starting from the date your account is opened. Offer Ends 4/1/2026.
• $2,500 Medallion(R) Qualification Dollars with MQD Headstart each Medallion Qualification Year and earn $1 MQD for each $20 in purchases on your Delta SkyMiles(R) Platinum American Express Card with MQD Boost to get closer to Status next Medallion Year.
• $150 Delta Stays Credit. Get up to $150 back annually on eligible prepaid hotels or vacation rentals through Delta Stays on delta.com.
• $120 Resy Credit. Get up to $10 in statement credits each month after you pay with your enrolled Delta SkyMiles(R) Platinum American Express Card to dine at U.S. Resy restaurants or make other eligible Resy purchases. Enrollment required.
• $120 Rideshare Credit. Up to $10 back in statement credits each month on U.S. rideshare purchases with select providers using your Delta SkyMiles(R) Platinum American Express Card. Enrollment is required.
• 15% off discount on Award Travel booked through delta.com and the Fly Delta app. Applies to Delta flights only, not applicable to partner-operated flights or taxes and fees.
• Up to $120 Global Entry Fee Credit. You can get either a $120 statement credit every 4 years for a Global Entry application fee or a statement credit up to $85 every 4.5 years for a TSA PreCheck(R) (through a TSA official enrollment provider) application fee, when charged to your Delta SkyMiles(R) Platinum American Express Card. Card Members approved for Global Entry will also receive access to TSA PreCheck at no additional cost.
• Companion Certificate benefit. Enjoy a Companion Certificate on a Delta Main round-trip flight within the U.S. and to Mexico, the Caribbean, or Central America each year after renewal of your Card. The Companion Certificate requires payment of government-imposed taxes and fees of between $22 and $250 (for itineraries with up to four flight segments). Baggage charges and other restrictions apply. Delta Basic experiences are not eligible for this benefit.
• First checked bag free (worth $70 roundtrip, per person) on Delta flights. This perk is worth up to $280 per round trip for a family of four ($35 each way, per person).
• Receive Zone 5 Priority Boarding on Delta flights; board early, stow your carry-on bag and settle in sooner.
• 3X Miles on Delta purchases and purchases made directly with hotels.
• 2X Miles at restaurants worldwide including takeout and delivery in the U.S., and at U.S. supermarkets.
• 1X Miles on all other eligible purchases.
• No Foreign Transaction Fees.
• $350 annual fee.

The Platinum version can be a worthy upgrade from the Gold version if you can take advantage of the added perks including Resy/Rideshare credits and especially the annual Main Cabin Companion Certificate (i.e. you plan to book two tickets together on Delta at least once a year). I’ve used it several times in the past and it is easy to use while booking tickets online at Delta.com. My savings from using the Companion Certificate for Delta Main has exceeded $500.

100,000 Skymiles is worth at least $1,000 in Delta airfare. Delta offers a minimum value out of your Skymiles via the “Pay with Miles” option. For example, that means 50,000 Skymiles can reduce the price of your Delta ticket(s) by $500 at the very least. (5,000 mile = $50 minimum redemption.) You can still search and book traditional award tickets and possibly get better value.

Automattic and the Internet Archive have released a free, open-source WordPress plugin that automatically detects broken outbound links on a site and redirects visitors to archived Wayback Machine copies instead of serving them a 404 error. The Internet Archive Wayback Machine Link Fixer, which launched last fall and is available on WordPress.org, runs in the background scanning posts for dead links, checking for existing archived versions, and requesting new snapshots when none exist. It also archives a site's own posts whenever they are updated. If the original link comes back online, the plugin stops redirecting. Pew Research has found that 38% of the web has disappeared over the past decade, and WordPress powers more than 40% of websites online.
