CentOS, RHEL (Red Hat Enterprise Linux), Fedora and other clones of RHEL, such as Oracle, Alma, and Rocky, offer support for version pinning. This feature allows developers and system administrators to lock a particular package to a specific version, preventing it from being automatically updated by yum or dnf commands. Sometimes, it is necessary to protect packages from being updated to newer versions to avoid incompatibility issues with your applications. For example, you can lock down PHP version 8.3.6 and avoid using updated PHP version 8.4. Let us see how to lock a package to a specific version, only exclude a package from yum update or dnf update on a CentOS, RHEL, Fedora, and friends.

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!

Steam Survey for February 2026 shows a big swing to Simplified Chinese  GamingOnLinux

Steam Survey Results Published For February 2026  Phoronix

"Saturn and some of its 274 moons are pretty weird," writes Smithsonian magazine: [Saturn moon] Titan has strangely few impact craters, Hyperion is tiny and misshapen, and Iapetus has a tilted orbit. What's more, planets tend to wobble along their rotational axes as they spin, like an off-kilter spinning top in the moments before it topples over. Formally called precession, scientists have long thought that Saturn's wobble rate should match Neptune's because they're probably gravitationally linked. However, data from NASA's Cassini spacecraft, which studied the ringed planet from 2004 to 2017, revealed that Saturn's precession rate is slightly speedier than Neptune's. In 2022, some researchers suggested that the destruction of a hypothetical moon, called Chrysalis, around 160 million years ago may have knocked Saturn out of sync and formed the pieces that became the planet's rings. But this work implied that Chrysalis probably would've crashed into Titan, posing a major problem, study co-author Matija Äuk, an astronomer at the SETI Institute, tells New Scientist's Leah Crane. In that case, Chrysalis' debris couldn't have become the rings, he says. So, Äuk and his colleagues used computer simulations to investigate what would happen if Chrysalis did smack into Titan. If that happened around 400 million years ago, they found, the crash would've wiped away Titan's craters and made its orbit more elliptical. The altered path may have slowly pushed the trajectories of other moons, which then scraped against one another and left chunks of ice and rock that now make up Saturn's rings. The timing seems to align with the rings' estimated age of roughly 100 million years. Additionally, one piece of kicked-up debris may have formed the weird moon Hyperion, which may have subsequently tilted the orbit of the moon Iapetus, according to the analysis. The scenario could also resolve Saturn's unexpected wobble, which is currently "a little bit too fast," Äuk tells Jacopo Prisco at CNN. The study has been accepted for publication in the Planetary Science Journal, and is already available on the preprint server arXiv.

Robinhood is running “HOOD Rewards Season” from 2/19-3/25, which includes the return of some competitive account transfer bonuses. Noteworthy are the 3% total match if you have $10,000 in margin (which you can “create” beforehand) and the 2% match that includes 401k rollovers. However, note that they have very long minimum holding periods where you are stuck at Robinhood (and can’t pursue other opportunities) or they will clawback the bonus. Transfers must be initiated by March 25, 2026 to qualify.

• 2% bonus on ACATS transfers to your Robinhood joint or individual taxable brokerage account from an external brokerage. 5-year minimum hold period + Robinhood Gold ($5/mo or $50/year) membership for a year required.
• 3% total bonus on ACATS transfers (1% extra) with a margin balance of $10,000 or more to your Robinhood joint or individual taxable brokerage account from an external brokerage.
• 2% bonus on ACATS transfers to your Robinhood IRA, including 401k rollovers. 5-year minimum hold period + Robinhood Gold ($5/mo or $50/year) membership for a year required.
• 3% bonus on IRA contributions. This is a standard offer for Robinhood Gold customers, but still worth noting if you are joining the Robinhood ecosystem. 5-year minimum hold period.
• Robinhood will also cover outgoing transfer fees (up to $75) if you transfer $7,500+ in assets.
• Additional unknown promo will drop on March 3rd, 2026. They are also announcing new products/features on March 4, 2026.

Full terms at Robinhood.com/hoodrewardstransfer.

The 2% bonus on taxable account transfers requires a subscription with Robinhood Gold ($5/mo) and customers must stay subscribed to Gold for 1 year after receiving each Gold match to keep the full Gold match. A 1% match is available to non-Gold customers, no subscription required. The funds that earned the match be kept in the account for at least 5 years to avoid a potential chargeback of the bonus. Transfer must be initiated by March 25,2026 to qualify. Offer only applies to self-directed individual or joint taxable accounts. For more information refer to Hood Season Account Transfer Bonus at robinhood.com/hoodrewardstransfer??

The additional 1% margin bonus is available to all customers who are approved for a margin account and transfer a margin balance of at least $10,000 using ACATS.

If you don’t want to move your money around all the time, I think this is a pretty good promo. If you move over a $100,000 portfolio for 5 years, that’s $3,000. If you move over a $1,000,000 portfolio for 5 years, that’s $30,000. If you have a $100,000 portfolio parked at Merrill Edge, given the upcoming Preferred Rewards changes, compare this bonus against potential cash back. Might be better to take the upfront money than to chase a higher tier. Robinhood now has over $300 billion in assets under custody.

It’s not hard to “create” a $10,000 margin balance by buying some extra SGOV/VBIL in your account right before the ACAT transfer (assuming you have enough equity collateral), do the transfer, and then pay off the margin by selling the SGOV/VBIL right after the transfer is completed. You’ll just pay a little margin interest in the meantime, should be less than $10 as your SGOV/VBIL will earn interest as well (price should increase in interim if no dividend distribution). Robinhood wants investors that use margin, as they tend to be more profitable.

As the Mobile World Conference begins in Spain, Lenovo brought a new attachable accessory for their laptops — an AI agent. CNET reports: The little circular module perches on the top of your Lenovo laptop display, attached via the magnetic Magic Bay on the rear. The module is home to an adorable animated companion called Tiko, who you can interact with via text or voice... [I]t can start and stop your music, open a web page for you or answer a question. You can also interact with it by using emoji. Give it a book emoji, for example, and it will pop on its glasses and sit reading with you while you work... The company wants to sell the Magic Bay accessory later this year — although it doesn't know exactly when, or how much it will cost. It even comes with a timer (for working in Pomodoro-style intervals) — but Lenovo has also created another "concept" AI companion that CNET describes as "a kind of stationary tabletop robot, not dissimilar to the Pixar lamp, but with an orb for a head." With a combination of cameras, microphones and projectors, the AI Workmate can undertake a variety of tasks, including helping you generate and display presentations or turn your written work or art into a digital asset... It's robotic head swivelled around and projected the slides onto the wall next to me. Lenovo created a video to show this "next-generation AI work companion" — with animated eyes — "designed to transform how modern professionals interact with their workspace." It bridges the physical and digital worlds — capturing handwritten notes, recognizing gestures, summarizing tasks, and proactively helping you stay ahead of your day. The moment you sit down, Lenovo AI Workmate greets you, surfaces priority tasks, and keeps your work organized without switching apps or losing context. From turning sketches into presentations to projecting information for instant collaboration, [it] brings on-device AI intelligence directly to your desk — secure, responsive, and always ready... It's not just software. It's a smarter way to work. It looks like Lenovo once considered naming it "AI Sphere" (since that name still appears in its description on YouTube). Lenovo also showed another "concept" laptop idea that PC Magazine called "futuristic": The ThinkBook Modular AI PC looks like a traditional laptop at first glance, but a second, removable screen fastens onto the lid. You can swap that screen onto the keyboard deck (in place of the keyboard, which can then be used wirelessly), or use it alongside the laptop as a portable monitor, attached via an included cable.... While Lenovo is still working on this device, and it's very much in the concept phase, it feels like one of its best-thought-out prototypes, one likely to make it to store shelves at some point. Another "concept" laptop is Lenovo's Yoga Book Pro 3D Concept, ofering directional backlight and eye-tracking technology for the illusion of 3D (playing slightly different images to each of your eyes). It offers gesture control for 3D models, two OLED displays, and some magical "snap-on pads" which, when laid on the display — make the GUI appear on the screen for a new control menu to "provide quick-access shortcuts for adjusting lighting, viewing angle, and tone".

Why the Linux 7.0 development cycle is off to a volatile start  Neowin

Linux Release Roundup (February 2026)  OMG! Ubuntu

If U.S. automakers turn their backs on electric vehicles, "their sales outside the U.S. will shrivel," warns Bloomberg. [Alternate URL.] They're already falling behind on the technology, relying on a 100% U.S. tariff on Chinese EVs to keep surging rivals like BYD Co. at bay.... While the American automakers "mostly understand the challenge in front of them, they don't have full plans" to confront it [said Mark Wakefield, head of the global automotive practice at consultant AlixPartners]... "Now is a great time for the V-8 engine," said Ryan Shaughnessy, the Mustang's brand manager. "We've done extensive customer research in multiple cities, looking at a variety of powertrains, and the V-8 is always the number-one choice." It isn't just customers. U.S. automakers have long been run by "car guys:" enthusiasts who live for the bone-shaking rumble of a big engine. For them, quiet and smooth EVs — even the absurdly fast ones — can't satisfy that craving. They're convinced many American car buyers share the same enthusiasm for what Shaughnessy described as "the sound and roar of the V-8." Wall Street couldn't be happier with the new direction... Ford's fortunes are also on the rise, as it's predicting operating profits could grow by as much as 47% this year to $10 billion. Ford's stock has risen nearly 50% over the last 12 months. Under the previous environmental rules, automakers effectively had to sell zero-emission vehicles in growing numbers to offset their gas-guzzlers. When they fell short, they had to buy regulatory credits from EV companies such as Tesla Inc. or face penalties. GM spent $3.5 billion on credits from 2022 to the middle of 2025. Now, according to JPMorgan Chase & Co. analyst Ryan Brinkman, GM and Ford each have "billion dollar tailwinds"... [T]he hangover from all that new horsepower could leave US automakers lagging their Chinese rivals who already build the world's most advanced — and lowest priced — electric cars. Indeed, there is much talk in Detroit about the competitive tsunami that will be unleashed on American automakers once Chinese car companies find a way to break through trade barriers now protecting the US market. [Ford Chief Executive Officer Jim] Farley even calls it an "existential threat"... "They're going to build as many V-8 engines and big trucks as they can get out the factory doors," said Sam Fiorani, vice president of vehicle forecasting for consultant Auto Forecast Solutions. "And as the rest of the world develops modern drivetrains, newer batteries and better electric vehicles, GM and Ford in particular are going to find themselves falling even further behind." The article notes GM "continues to develop battery-powered vehicles, and CEO Mary Barra said the automaker would begin offering a 'handful' of hybrids soon," while Ford and Stellantis "have plans to launch extended-range electric vehicles, or EREVs, a new kind of plug-in hybrid with an internal combustion engine that recharges the battery as the vehicle drives down the road." But while automakers may be investing in future EV vehicles, they're also "leaning into the lucre that comes from selling millions of fossil-fuel vehicles in a rare moment of loosened regulation."
