Phone Camera Technology

Mike Elgan praises the multitude of roles that camera sensors play in modern smartphone apps .

Elgan notes, "Already, smartphone cameras can identify and provide additional information about whatever we point them at. They enable us to harvest visual data from, and see augmented reality objects placed in, the real world. Front-facing cameras can improve security through face recognition" (para. 28). Elgan notes that cameras with multiple lenses are now the norm, and the number of sensors will only increase with apps such as Camfind and Photomath. -DD

Tim Berners-Lee and Individual Freedom

Katrina Brooker interviewed Tim Berners-Lee, the scientist who helped develop the standards of the Internet. Now that half of the world population has some type of Internet access, Berners-Lee expresses anger at how the technology has been used:

...the Web had failed instead of served humanity, as it was supposed to have done, and failed in many places. [The increasing centralization of the Web] ended up producing—with no deliberate action of the people who designed the platform—a large-scale emergent phenomenon which is anti-human.
Berners-Lee expresses concern about the growth of both Internet firms and government agencies that eliminate individual's privacy or promote hidden agendas.

Berners-Lee is now working on technologies for decentralizing information, including software called Solid. Disciples are developing protocols to create a Web of Trust, such as ActivityPub.

Coffee as a Medication

Kashmira Gander reports in Newsweek on UK research indicating that moderate coffee drinking can have both positive and negative effects on the human body.

Gander notes that:

Past studies have indicated an inverse association between drinking coffee and the risk of developing chronic conditions such as heart disease, diabetes, Parkinson’s and cancers of the liver, bowel, colon and endometrium. But evidence also suggests caffeine could cause high blood pressure or heart attacks in those who find it tough to metabolize.
Gander says that safe consumption is typically defined as less than six cups a day, though there are genetic differences in humans which make some people more or less sensitive to caffeine. Those drinking more coffee still seem to live longer than their peers who abstain.

Coffee drinking may correlate with health without causing health. My thought is that those whose lifestyle includes daily drinking many cups of coffee may have other significant lifestyle factors which tend to be present among those they are not about to die. For example, it can be inferred that heavy coffee consumption means that an individual has significant disposable income. Or coffee consumption may be a by-product of an active social life, or consumed to "power through" tasks that provides a sense of purpose.

What Does It Mean to Be a "Christian Nation"

Mark Galli, Editor of Christianity Today, for July 4th reviews the claim that the United States is a Christian nation .

Galli's response in his final paragraph is sharp:

But let us not proclaim that we are a Christian nation founded on Christian principles. That is a lie—one might even call it a blasphemy. America is a great and terrible nation, like so many others (“terrible” meaning having done dreadful things but also “formidible in nature”). Let us continue to love it, as we love our flawed families and friends. Let us continue to serve it as God leads us to. Let us continue to reform it, as has been the practice of every generation. And most of all, let us continue to pray for it, that God would continue to have mercy on us and on our children, and on our children’s children to the third and fourth generation.
