Submission + - Facebook's plan to fight propaganda with radical transparency was too radical (fastcompany.com)

tedlistens writes: Social Science One, an unprecedented, Mark Zuckerberg-backed plan to open up Facebook's data to outside researchers—with the aim of fighting disinformation and propaganda ahead of elections in 2020—has run up against privacy concerns at Facebook. A month after the funders' deadline, Facebook continues to work on treating the data with differential privacy techniques and says it hopes to publish more datasets soon. But researchers are frustrated and confused, and the backers are reconsidering their support. And lawmakers like Sen. Mark Warner, the vice chair of the Senate Intelligence Committee, are growing impatient too.

“In Congress, we need to require greater accountability from social media platforms on everything from the transparency of political ad funding, to the legitimacy of content, to the authenticity of user accounts,” Warner tells Alex Pasternack at Fast Company. “And if platforms refuse to comply, we need to be able to hold them responsible.”

Submission + - How Flagstaff, Arizona, Switched To LEDs Without Giving Astronomers a Headache (arstechnica.com)

An anonymous reader writes: Flagstaff became the first city to earn a designation from the International Dark Sky Association in 2001. That came as a result of its long history of hosting astronomy research at local Lowell Observatory, as well as facilities operated by the US Navy. The city has an official ordinance governing the use of outdoor lighting—public and private. A few years ago, though, a problem arose. The type of dark-sky-friendly streetlight that the city had been using was going extinct, largely as a casualty of low demand. In fact, as of this summer, there are none left to buy. Meanwhile, the age of the LED streetlight has arrived with a catch: limited night-sky-friendly LED options. The problem with LEDs boils down to blue light. Older streetlights are high-pressure sodium bulbs, which produce a warm yellow glow around a color temperature of 2,000 K. The bulbs Flagstaff relied on for most of its streetlights were low-pressure sodium—a variant that only emits light at a single wavelength (589 nanometers) near that yellow color, producing something resembling candlelight. Many of the LED streetlights on the market have much cooler color temperatures of 3,000 or even 4,000 K.

[...] Narrow-band amber (NBA) LEDs [...] actually use a type of LED that only emits warmer colors from the start. In this way, they actually compare pretty well to the low-pressure sodium streetlights that recently went extinct. The range of wavelengths emitted is a little broader, but the practical effect is about the same. Separately from all this wavelength wrangling, though, LEDs do have a strong natural advantage—they’re highly directional. That is, LED streetlights do a much better job of only lighting the street (rather than the adjacent homes). That means that fewer lumens coming out of the fixture can give the same result you had before. Flagstaff’s plan is generally to swap in NBA LEDs for all the low-pressure sodium lights, and PCA LEDs for the high-pressure sodium lights that are used along the busier streets (as they’re a little brighter). The better directionality of LEDs—combined with resident requests for slightly dimmer lighting on residential streets—actually means that the total output of the city’s streetlights is going to drop from about 29 million lumens to about 19 million lumens. That’s not unusual.

With the exception I'm not whining about it. I'm actually laughing my ass off right now. But the troll mod abuse is a problem that needs to be addressed.

Except that you are whining.

In one breath, "Haha, look at all those pissed off snowflakes!" In the second breath, "Mommy slashdot, do something about the mods marking me as troll!" You have the right to say anything here, you don't have the right to be free from the consequence of saying it. Snowflake.

Use the abuse flag to flag these toll mods as abuse. This problem needs to be corrected on those doing this need to have their mod priv suspended.

So... No irony on how you stated that you're "Pissing off the snowflakes" and then whine about THIS one post later? Sounds like snowflake behavior right there.

Perhaps you missed the part about me stating I'm ignoring the "well-known" part since Rooster himself is unable to name the persons who threw the man off the building? The persons I listed might as well have been just as anonymous as the person(s) used in Rooster's example since you yourself admit you don't know them and at least meet the LOW LOW bar he originally set to prove that "people other than xian conservatives" hate the lgbt community. He gave an example, then moved the goal-posts. Now, my familiarity with the list may be a tad unfair since I'm actually a member of the LGBT community and these things show up on my radar regularly and I was familiar with at least half them, particularly the Salvation Army entry. I stand by this list as I gave it the same low bar of entry Rooster originally used when he tried to use the incident with the dude being thrown to make his point. The list DOES contain those with probably more power and influence than the person(s) throwing the gay man from a tall building. If you can name the masked men, then maybe you'll have a point. Otherwise, deal with this list as you've done nothing to disprove it only state that you don't recognize anyone on it.
