Honestly, SB has been security theater from the beginning because it depended on at least three entities the user and/or developers had no control over to certify the chain-of-trust is uncompromised. //

This is why many people in Linux land don't turn on SB. It's causing more trouble than its worth, given how easily it's bypassed on most hardware. And that's why I pointed out about the two conditions for SB to be useful. A) the UEFI options must default to fail to safe - refuse to boot (which most of the time they don't), B) Microsoft nor the OEMs can be part of the chain of trust, it must be entirely local and auditable. Those two conditions are also why it'll never properly function on consumer grade hardware.

New study confirms 2024 “momentum flux theory” on how angular momentum of water flows drives rotation.

A typical lawn sprinkler features various nozzles arranged at angles on a rotating wheel; when water is pumped in, they release jets that cause the wheel to rotate. But what would happen if the water were sucked into the sprinkler instead? In which direction would the wheel turn then, or would it even turn at all? That’s the essence of the “reverse sprinkler” problem that physicists like Richard Feynman, among others, have grappled with since the 1940s. Now, applied mathematicians at New York University think they’ve cracked the conundrum, per a recent paper published in the journal Physical Review Letters—and the answer challenges conventional wisdom on the matter. //

Mach proposed that there would be no rotation with a reverse sprinkler: the reaction force on the nozzle as it sucks in water pulls the nozzle counter-clockwise, while the water flowing into the inside of the nozzle pushes it clockwise. The two forces cancel each other out in this steady-state scenario. Feynman’s own experiment showed a slight tremor when pressure was first applied to pump water through the nozzle, and then the sprinkler returned to its original position and remained still.

But others suggested that if the friction was low enough and the inflow rate high enough, a reverse sprinkler will start to turn in the opposite direction of an ordinary sprinkler, thanks to the formation of a vortex inside.

Jesus confronted the disciples’ distorted belief system: “It was not that this man sinned, or his parents, but that the works of God might be displayed in him” (John 9:3, ESV).

This poor blind beggar had suffered greatly throughout his life. We don’t know if he heard the disciples’ question to Jesus or not, but here’s what we do know: Jesus immediately defended him. Had this man sinned? Of course he had. And so had his parents. But Jesus clarified this wasn’t the cause of his suffering. Not only did Jesus challenge their simplistic view of suffering and ultimately point them to the greater purpose of his glory; he also fiercely defended a help­less man. Jesus was like a father stepping in front of a child: To get to him, you’ll first have to go through me.

What a Savior we have—forgiver of the sinner, helper of the helpless, defender of the defenseless. Yes, he came to expose the darkness of hearts, but he also came to shine the light of his hope and glory into the dark places of our pain (v. 5). It’s tempting to as­sume God looks at our pain and wonders, Why are you struggling? Don’t you see that I’m doing something through it?

But Jesus’ heart is empathetic, not critical. His life on earth shows us how much he still em­pathizes and grieves with us over the brokenness of the world. And everything he does brings him the greatest glory and us the greatest good (Rom. 8:28).

If we question that truth, we’ll constantly question his heart for us when we can’t understand his ways. But Psalm 56 assures us, “This I know, that God is for me” (v. 9, ESV). Our faith will be bolstered when it’s founded on the knowledge that God is undeniably, without a doubt, for us. //

Friend, your suffering isn’t God’s punishment, and it’s never pointless. Jesus is always at work in ways we can’t see in the mo­ment. And it’s always for the purpose of showing the goodness and glory of God to us, in us, and through us.

Still, we think, If I just knew why, then I could endure. But what we ultimately need more than anything else is not the light that shines on the answers we want but the light of Jesus himself.

Jesus could have explained the man’s blindness, but he didn’t. That wasn’t what the man really needed. Yes, it would have been God’s undeserved grace to spare him from a gene mutation, disease, or whatever caused his blindness. His life would have been easier. Had that been the case, though, would he have come face to face with Jesus? Maybe not. He would have been content with his physical sight, despite walking in spiritual darkness. But in the hands of a powerful God, it was also an undeserved grace for the blind beggar’s life to become a remarkable story of redemption that led him (and those around him) to spiritual sight.

You may not see it now, but answers to your pain won’t bring ultimate comfort. Only nearness to Jesus will. Jesus wants what is best for you and has the power to bring it about.

The Making of the Voyager Golden Record

Many Christian parents struggle with the use of magic in literature. Some feel uncomfortable with any magical elements, while others object only to those associated with witchcraft. I’ve had many online conversations with parents who struggle to articulate exactly “how much” magic they’re willing to allow in their kids’ books. I myself have wrestled with this issue, seeking a biblical approach and landing in various places at different times. My goal here is to provide you with an introduction to this topic, and to equip you with perspectives to approach it biblically and practically. Although I love literature, I love the word of God far more. I know I will have to give an account to the Lord for everything, and I deeply desire to represent his word well, despite my fallibility. Having said this, I realize you may come to different conclusions than I have. //

When I approach fantasy literature that includes magical elements, I try to look through a similar lens and ask the questions “Where does this power originate?” and “What are the practitioner’s intentions?” Remember that when an author writes in the genre of fantasy, his or her intent is (usually) not to encourage belief in fantastical events but rather to help the reader recognize the deeper truths that the imaginative elements of the story convey. Oftentimes, the author points to spiritual truths more effectively illustrated outside the bounds of our own reality. Well-written fantasy won’t focus on the magical elements themselves; rather, any magic will simply be a creative vehicle to highlight good versus evil and to reveal the truth that spiritual forces are at work in the world. ////

The Trump administration on Monday barred US citizens in the Democratic Republic of the Congo from returning home amid an Ebola outbreak that continues to outpace response efforts.

Reuters first reported late Monday that Americans currently in the DRC or those who have recently traveled to the Ebola-stricken country have been put on a “do-not-board” list. They cannot travel back to the US until they have spent 21 days in a third country. The order, taken under a transportation authority known as Title 49, was independently confirmed by Politico on Tuesday.

Both outlets noted that roughly two dozen Americans who had been set to board flights home on Tuesday have already been blocked by the new rule. It remains unclear if the bar also applies to government workers. The Centers for Disease Control and Prevention has at least two dozen employees working in the DRC.

The move adds to the already extremely stringent and controversial travel restrictions imposed by the Trump administration in an effort to wall itself off from the outbreak. Health experts continue to be critical of such restrictions, as they have historically been unsuccessful and harmful. Specifically, they discourage countries and people from being transparent about outbreaks and disease risks, hurt economies, and create stigma. There is also concern that such restrictions will limit humanitarian aid workers. //

The US has built an elite network of medical facilities that can safely isolate Ebola patients while offering high-quality care.

In past Ebola outbreaks, no such stringent travel restrictions were implemented, and the US repatriated eight cases for high-level care. None of the repatriated patients transmitted the virus.
