Today the Ocean Cleanup unveiled its new "Interceptor" solar-powered robot to collect waste plastic from rivers before it can enter the ocean, Fast Company reports: The system was designed by the nonprofit The Ocean Cleanup, which spent the past four years secretly developing and testing the technology while it continued to work on its main project -- a device that can capture plastic trash once it's already in the ocean. The nonprofit unveiled the Interceptor at an event in Rotterdam today.

The ocean's plastic trash problem often starts in rivers: Every year, as much as 2.4 million metric tons of plastic flows from rivers to the sea, the nonprofit estimates. Most of that trash comes from rivers in Asia, in cities where recycling infrastructure is often inadequate. Around 1% of the world's rivers, or 1,000 rivers in total, are responsible for the majority of the trash entering the ocean...

The new technology is designed to anchor to a riverbed, out of the path of passing boats. Like the system that the nonprofit designed for the ocean, which uses a large barrier that blocks part of the river to collect plastic as it floats by, the Interceptor has a floating barrier that directs trash into the system. The device is positioned where the greatest amount of plastic flows, and another device can be placed farther down the river to catch trash that might escape the first Interceptor. A conveyor belt pulls the trash out of the water, and an autonomous system distributes it into dumpsters on a separate barge, sending an alert to local operators when the system is full and ready to be taken to a recycler. The system runs on solar power. In a typical day, it might extract as much as 50,000 kilograms of trash; depending on the currents, tides, and how much plastic is in a given river, The Ocean Cleanup estimates it could theoretically collect as much as 100,000 kilograms [220,462 pounds]...

Since it runs autonomously, it needs little human interaction and also doesn't require humans to sort through potentially dangerous debris collected from the water. It's designed to be mass-produced. The nonprofit aims to deploy it into all of the most polluting rivers in the next five years... "We project that we can remove 90% of floating ocean plastic by 2040, and to truly rid the world's oceans of plastic we must do two things: cleanup legacy plastic and stop it from entering the ocean," they wrote in a press release. "Both are necessary to achieve this mission..."

There was some trouble last weekend at the world's largest package repository. An anonymous reader quotes the official npm blog: On Saturday, January 6, 2018, we incorrectly removed the user floatdrop and blocked the discovery and download of all 102 of their packages on the public npm Registry. Some of those packages were highly depended on, such as require-from-string, and removal disrupted many users' installations... Within 60 seconds, it became clear that floatdrop was not a spammer -- and that their packages were in heavy use in the npm ecosystem. The staffer notified colleagues and we re-activated the user and began restoring the packages to circulation immediately. Most of the packages were restored quickly, because the restoration was a matter of unsetting the deleted tombstones in our database, while also restoring package data tarballs and package metadata documents. However, during the time between discovery and restoration, other npm users published a number of new packages that used the names of deleted packages. We locked this down once we discovered it, but cleaning up the overpublished packages and inspecting their contents took additional time...

In cases where the npm staff accepts a user's request to delete a package, we publish a replacement package by the same name -- a security placeholder. This both alerts those who had depended on it that the original package is no longer available and prevents others from publishing new code using that package name. At the time of Saturday's incident, however, we did not have a policy to publish placeholders for packages that were deleted if they were spam. This made it possible for other users to publish new versions of eleven of the removed packages. After a thorough examination of the replacement packages' contents, we have confirmed that none was malicious or harmful. Ten were exact replacements of the code that had just been removed, while the eleventh contained strings of text from the Bible -- and its publisher immediately contacted npm to advise us of its publication.
They're now implementing a 24-hour cooldown on republication of any deleted package names -- and are also updating their review process. "As a general rule, the npm Registry is and ought to be immutable, just like other package registries such as RubyGems and crates.io... However, there are legitimate cases for removing a package once it has been published. In a typical week, most of the npm support team's work is devoted to handling user requests for package deletion, which is more common than you might expect. Many people publish test packages then ask to have them deprecated or deleted. There also is a steady flow of requests to remove packages that contain contain private code that users have published inadvertently or inappropriately."

An anonymous reader shares a report: Is the typical Spanish daily schedule about to change forever? For decades, campaigners in the country have complained that the average Spaniard's habit of keeping extremely late hours and taking delightfully long lunch breaks was making everyday life harder for citizens. This week, change could finally be on the way, as 110 professional bodies in Catalonia have signed up to a plan to change the region's daily timetable by 2025, shortening the classic three-hour lunch break so that employees can finish work earlier in the evening. Such a change would radically reshape ordinary people's lives -- and controversially, it could drive a wedge between Catalonia and the rest of Spain, where the national government supports similar changes (and has adopted a shorter break for public offices) but hasn't yet fixed a timetable for action. You could call the plan an end to national harmony, a blessed release for hard-pressed workers, or an attack on the Spanish way of life. Whatever you do, however, don't call it the end of the siesta. That's because the beloved and much-misunderstood Spanish tradition of the afternoon nap more or less died out decades ago. What remained is a highly distinctive national timetable not found in any other European country, where it has often been read as a peculiarly exotic form of madness. The average Spanish working day is certainly unusual in shape. After starting work between 8 and 9 a.m., hungry workers hold out for a lunch break scheduled as late as 1:30 or 2:30. As if in compensation for this long wait, many then stay off-duty for a break of up to three hours, filling it with a protracted multi-course lunch and maybe a stop at a "nap bar." Most stores and many businesses close down until the late afternoon, before a final burst of office hours between 5:30 and 8 (or sometimes 4 to 7). Spaniards then head home at an hour when most people in other countries are cleaning up their dinner dishes, rarely getting food on the table any earlier than 10 p.m. This pushes bedtime past midnight for many.

A while ago you had the chance to ask Steve Jackson, founder and editor-in-chief of Steve Jackson Games, about the numerous games he's created, his efforts to digitize those games, and what to do when the Secret Service shows up at your office. Below you will find his answers to your questions.

An Anonymous Coward writes: "John Looney recently posted to the lkml, asking about the possibility of one computer serving multiple users. That is to say, multiple keyboards, mice, monitors, etc, hooked up to a single server. The advantages of such a setup in a lab type environment are obvious. The following discussion ranges through several technical issues with such a configuration, including a kernel limitation of one virtual terminal active at a time, and the typical lack of quality in long video cables. However, none of the issues raised are unbeatable. James Simmons, for example, has been working on cleaning up the virtual terminal code, with many related fixes already merged into Dave Jones' tree."

Robots have been around in concept for longer than the word itself has been used to describe them, and for most of this century they've had a fair hold on the public imagination as either Utopian saviors or inexorable villains. Reader mtDNA sent in the evaluation below of a book called Robo sapiens: Evolution of a new species which may be the basis for a more realistic and neutral understanding about Robots, especially well suited to non-experts in that field. (I also found the other books in the series excellent.)

This week's interview with Nobel Prize-winning physicist Leon M. Lederman was conducted verbally, in person, by Slashdot reader Rich Wellner, who transcribed everything you'll read below. A lot of work! (Thanks, Rich.) The questions he asked were the creme de la creme of those you submitted Monday.

Monday's questions for the Cult of the Dead Cow ranged from serious-tech to silly. Various members of the Cult answered appropriately. Great stuff! One warning: if you are offended by strong language or are a hacker under 18, you should not read this Q&A session. The Cult is one of those groups the assorted nanny-censor programs try to keep away from deity-fearing, good-citizen, mass-average folks because they're commie anachist no-gooders. Or something like that. (And we like them that way!) Click below to learn why these people are A Danger to the Established Order(tm).
