Obama Asks Congress To Renew 'Patriot Act' Snooping 389

mi writes: President Obama has asked the Senate to renew key Patriot Act provisions before their expiration on May 31. This includes surveillance powers that let the government collect Americans' phone records. Obama said, "It's necessary to keep the American people safe and secure." The call came despite recent revelations that the FBI is unable to name a single terror case in which the snooping provisions were of much help. "Obama noted that the controversial bulk phone collections program, which was exposed by National Security Agency contractor Edward Snowden, is reformed in the House bill, which does away with it over six months and instead gives phone companies the responsibility of maintaining phone records that the government can search." Obama criticized the Senate for not acting on that legislation, saying they have necessitated a renewal of the Patriot Act provisions.

We aren't talking about millions of years timescale here. According to TFA, the last eruption was 33 years ago. This would make eruptions as much a part of the natural ebb and flow there as wildfires are in some areas.

No, this isn't a very "consoling fact", but it seems very anthropocentric to assume that nature is here to console you or any other human....

My point is that the characterization of a potential eruption as a "threat" to the ecosystem ignores the simple fact that the source of the "threat" is as natural a part of the ecosystem as the plants and animals that are being "threatened".

The species plants and animals that are living there have evolved in that place WITH the local geology. Periodic volcanic eruptions are an intrinsic PART of that particular ecosystem. The fact that the plants and animals are still there after untold numbers of past eruptions says something about how nature tends to shrug off these kinds of "threats".

It seems to me that using the word "threat" here is misplaced. This isn't something coming from outside this area to have a negative impact like your asteroid or some external pollution source. Yes, the eruption might very well change the biodiversity of the area in the short term. But such change itself is an intrinsic part of nature. It only seems to be considered as a bad thing by humans because some species of "cuddly animals" may be impacted.

Definition per the Wiki:

An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment (things like air, water and mineral soil), interacting as a system

The volcano would be one of the "nonliving components of the environment", which influences things around it (soil and air chemistry, microclimate, etc.), even in the periods between eruptions. Quite different to an inbound asteroid....

Comment Atomic clocks don't rely on nuclear decay..... (Score 1) 403

Nuclear decay being a chaotic process and all.

So-called "atomic clocks" utilize the RF absorption of various isotopes, typically Cesium or Rubidium. Heated to a vapor in a sealed chamber, the vapor is excited by a microwave RF source, and at a highly specific frequency, the vapor absorbs the RF energy. This phenomenon is used as part of a feedback loop to keep an electronic oscillator disciplined to whatever frequency is desired.

Atomic clocks won't work without electrical power, and would be subject to all the same physical rust and breakdown as other electronic devices over the years.

Religious Affiliation Shrinking In the US 866

gollum123 notes new U.S. demographic data from the Pew Research Center which show that the percentage of Americans declaring affiliation with a particular religion has declined sharply since 2007. Americans identifying as Christian dropped from 78.4% in 2007 to 70.6% in 2014. Those describing themselves as atheist, agnostic, or simple having no affiliation took up most of the slack, rising from 16.1% to 22.8%. Members of non-Christian faiths collectively rose from 4.7% to 5.9%. Despite the overall decline, the demographics within the Christian group are getting much more racially and ethnically diverse. The willingness of respondents to marry outside their religious affiliation is also on the rise. The median age of unaffiliated adults is dropping, while the median ages of mainline Protestants and Catholics are rising. The study estimates that 85% of adults age 70 and over are Christian, while only 56% of adults ages 18-24 are Christian. They also say that each individual generation has shown a slight decrease in religious affiliation compared to their statistics in 2007.

TV test pattern, because it has a stereotypical representation of a Native American on it....

The whole purpose of a standard image is to be able to make direct comparisons between your work and the work of others. For better or worse, the Lena image (cropped so as not to show the naughty bits) IS the standard test image in this field, much as the old Indian Head was in the days before color TV.

Cool! Several friends and I ran pirate FM intermittently for a bunch of years.

Anyone know where to get English subtitles for that film? Might be fun to compare to the handful of other pirate radio movies.

I was hoping to see more interest in local pirate TV when analog NTSC got shut down. The long reign of cable TV weaned enough people away from local antennas altogether, so viewer base probably limited in most areas.
