  • “Quite Divorced From Reality”: Climate Scientist, Activists Call Out Shell Exec at UN Conference – In These Times

    “This is quite divorced from reality, what you are all discussing,” Simon Lewis, a climate science professor at University College London, told the oil executives during a Q+A. Lewis went on to explain to the audience that even if polluters invested in every nature conservation, sustainability agriculture or other “natural climate solution” in the world, those projects would only offset about 20% of global greenhouse gas emissions; the vast majority of cuts would still have to come about through actual reductions in fossil fuel use. Given this, Lewis asked them to explain how the initiative was any different from other corporate schemes put forth in past decades—good PR that doesn’t actually tackle the problem. In addition, carbon offset trading—which has been going on at smaller scales for decades—is no silver bullet. It has had mixed results to date, including failed projects, outright fraud, and human rights abuses against rural, indigenous and other vulnerable communities, prompting fierce opposition from grassroots climate organizations against including carbon trading in the Paris Accord. The carbon trading question is one of the remaining thorny issues country negotiators are supposed to iron out during this two-week climate conference, which ends December 13. The rules for such “market-based solutions” (included in what is technically known as Article 6 of Paris Agreement) were supposed to be decided at last year’s meeting, but countries remain far apart; in fact, some observers wonder if it won’t be punted off again until next year. Meanwhile, the oil majors have yet to unveil a plan for reducing their own company emissions in line with the Paris Agreement, which calls for dramatically reducing fossil fuel use to prevent climate catastrophe.

  • What China’s Surveillance Means for the Rest of the World | Time

    Bakitali Nur, 47, a fruit and vegetable exporter in the Xinjiang town of Khorgos, was arrested after authorities became suspicious of his frequent business trips abroad. The father of three says he spent a year in a single room with seven other inmates, all clad in blue jumpsuits, forced to sit still on plastic stools for 17 hours straight as four HikVision cameras recorded every move. “Anyone caught talking or moving was forced into stress positions for hours at a time,” he says. Bakitali was released only after he developed a chronic illness. But his surveillance hell continued over five months of virtual house arrest, which is common for former detainees. He was forbidden from traveling outside his village without permission, and a CCTV camera was installed opposite his home. Every time he approached the front door, a policeman would call to ask where he was going. He had to report to the local government office every day to undergo “political education” and write a self-criticism detailing his previous day’s activities. Unable to travel for work, former detainees like Bakitali are often obliged to toil at government factories for wages as miserly as 35¢ per day, according to former workers interviewed by TIME. “The entire system is designed to suppress us,” Bakitali says in Almaty, Kazakhstan, where he escaped in May. The result is dystopian. When every aspect of life is under constant scrutiny, it’s not just “bad” behavior that must be avoided. Muslims in Xinjiang are under constant pressure to act in a manner that the CCP would approve. While posting controversial material online is clearly reckless, not using social media at all could also be considered suspicious, so Muslims share glowing news about the country and party as a means of defense.

  • Climate models have been correct for literally 40 years

    Well well well. Climate deniers have been making it up all along.

    According to the research published today, almost every peer-reviewed climate model of human-caused global temperature rise dating back to 1970 lines up with the warming we see today. “In scientific terms, we’d say there’s no bias,” the paper’s co-author Henri Drake, a PhD candidate at MIT, told me over the phone. “Once we accounted for the differences in CO2 emissions, 14 of the 17 models we analyzed were consistent with current observations.” “Taken together,” he added, “these climate models have always been quantitatively accurate.”

  • Low Carbon Kubernetes Scheduler

    ‘A demand side management solution that consumes electricity in low grid carbon intensity areas’:

    To justify Kubernetes’ ability or globally distributed deployments the researchers chose to optimize placement to regions with the greatest degree of solar irradiance termed a Heliotropic Scheduler. This scheduler is termed ‘heliotropic’ in order to differentiate it from a ‘follow-the-sun’ application management policy that relates to meeting customer demand around the world by placing staff and resources in proximity to those locations (thereby making them available to clients at lower latency and at a suitable time of day). A ‘heliotropic’ policy, on the other hand, goes to where sunlight, and by extension solar irradiance, is abundant. They further evaluated the Heliotropic Scheduler implementation by running BOINC jobs on Kubernetes.

  • Climate emergency: world ‘may already have crossed several tipping points’

    The world may already have crossed a series of climate tipping points, according to a stark warning from scientists. This risk is “an existential threat to civilisation”, they say, meaning “we are in a state of planetary emergency”. Tipping points are reached when particular impacts of global heating become unstoppable, such as the runaway loss of ice sheets or forests. In the past, extreme heating of 5C was thought necessary to pass tipping points, but the latest evidence suggests this could happen between 1C and 2C. The planet has already heated by 1C and the temperature is certain to rise further, due to past emissions and because greenhouse gas levels are still rising. The scientists further warn that one tipping point, such as the release of methane from thawing permafrost, may fuel others, leading to a cascade.

  • China’s Operating Manuals for Mass Internment and Arrest by Algorithm – ICIJ

    “The Chinese have bought into a model of policing where they believe that through the collection of large-scale data run through artificial intelligence and machine learning that they can, in fact, predict ahead of time where possible incidents might take place, as well as identify possible populations that have the propensity to engage in anti-state anti-regime action,” said Mulvenon, the SOS International document expert and director of intelligence integration. “And then they are preemptively going after those people using that data.” Mulvenon said IJOP is more than a “pre-crime” platform, but a “machine-learning, artificial intelligence, command and control” platform that substitutes artificial intelligence for human judgment. He described it as a “cybernetic brain” central to China’s most advanced police and military strategies. Such a system “infantilizes” those tasked with implementing it, said Mulvenon, creating the conditions for policies that could spin out of control with catastrophic results. The program collects and interprets data without regard to privacy, and flags ordinary people for investigation based on seemingly innocuous criteria, such as daily prayer, travel abroad, or frequently using the back door of their home. Perhaps even more significant than the actual data collected are the grinding psychological effects of living under such a system.  With batteries of facial-recognition cameras on street corners, endless checkpoints and webs of informants, IJOP generates a sense of an omniscient, omnipresent state that can peer into the most intimate aspects of daily life.  As neighbors disappear based on the workings of unknown algorithms, Xinjiang lives in a perpetual state of terror. The seeming randomness of investigations resulting from IJOP isn’t a bug but a feature, said Samantha Hoffman, an analyst at the Australian Strategic Policy Institute whose research focuses on China’s use of data collection for social control. “That’s how state terror works,” Hoffman said. “Part of the fear that this instills is that you don’t know when you’re not OK.”

  • “Brushing”

    An interesting Amazon scam:

    The end game here in many cases is for the seller to be able to pose as a verified purchaser and write a glowing review of their own product. Gaming the review system in this way pushes their products up higher in Amazon search results — regardless of whether the product is actually “good” or not. Amazon told CBS News that it investigates all customer reports of unsolicited packages like those made by the Gallivans. The company will shut down the accounts of vendors or reviewers found abusing the review system.

  • KIAM defaults result in massive latencies on AWS API calls

    KIAM [a Kubernetes IAM API helper] happens to provide short-lived credentials to Pods, which makes sense as it’s fair to assume that the average lifetime of a Pod is shorter than EC2 instances. The default is precisely 15 min. But if you put both defaults together, you have a problem. Each certificate provided to the application has a 15 min expiration time. The AWS Java SDK will force refreshing any certificate with less than 15 min expiration time left. The result is that every request will be forced to refresh the temporary certificate, which requires two calls to the AWS API that add a huge latency penalty to each request. We later found a feature request in the AWS Java SDK that mentions this same issue. The fix was easy. We reconfigured KIAM to request credentials with a longer expiration period. Once this change was applied, requests started being served without involving the AWS Metadata service and returned to an even lower latency than in EC2.

  • How A Massive Facebook Scam Siphoned Millions Of Dollars From Unsuspecting Boomers

    Since 2015, Ads Inc. has made money — lots of it — by executing one of the internet’s most persistent, lucrative, and sophisticated scams: the subscription trap. The subscription trap works by tricking people into buying what they think is a single free trial of a celebrity-endorsed product. Although the customers would receive the product — which in most cases was not made by Ads Inc. itself — in reality, the celebrity has nothing to do with the offer. And in purchasing the free trial, the customer unwittingly commits to a pricey monthly subscription designed to be hard to cancel. As for the products, a current employee described the diet and male enhancement offerings as, “the worst of the worst … China-made sawdust in a capsule.” But the subscription trap was just one part of Ads Inc.’s shady business practices. Burke’s genius was in fusing the scam with a boiler room–style operation that relied on convincing thousands of average people to rent their personal Facebook accounts to the company, which Ads Inc. then used to place ads for its deceptive free trial offers. That strategy enabled his company to run a huge volume of misleading Facebook ads, targeting consumers all around the world in a lucrative and sophisticated enterprise, a BuzzFeed News investigation has found.

    This is some horrifically dystopian shit from the UK:

    Tears filled the eyes of Danny Brice, 47, in London when he showed the Guardian how difficult he has found negotiating the UC programme with learning disabilities and dyslexia. “I call it the black hole,” he said. “I feel shaky. I get stressed about it. This is the worst system in my lifetime. They assess you as a number not a person. Talking is the way forward, not a bloody computer. I feel like the computer is controlling me instead of a person. It’s terrifying.” Nine million people in the UK are functionally illiterate and 5 million adults have either never used the internet or last used it more than three months ago. And yet many of these people rely on a “digital by default” welfare system.

Also, most countries will move to paying a pittance for solar exports, so self-consumption rate is becoming the most important financial parameter. 13. To financially assess a proposed rooftop solar system, you will need at least a year’s data on hourly electricity consumption to estimate selfconsumption. Also, get it built when you have scaffolding up for something else, scaffolding is expensive.

  • thoughts on rms and gnu — wingolog

    I can hear you saying it. RMS started GNU so RMS decides what it is and what it can be. But I don’t accept that. GNU is about practical software freedom, not about RMS. GNU has long outgrown any individual contributor. I don’t think RMS has the legitimacy to tell this group of largely volunteers what we should build or how we should organize ourselves. Or rather, he can say what he thinks, but he has no dominion over GNU; he does not have majority sweat equity in the project. If RMS actually wants the project to outlive him — something that by his actions is not clear — the best thing that he could do for GNU is to stop pretending to run things, to instead declare victory and retire to an emeritus role. Note, however, that my personal perspective here is not a consensus position of the GNU project. There are many (most?) GNU developers that still consider RMS to be GNU’s rightful leader. I think they are mistaken, but I do not repudiate them for this reason; we can work together while differing on this and other matters. I simply state that I, personally, do not serve RMS.

    “User research was carried out with a wide range of ethnic groups and did identify that people with very light or very dark skin found it difficult to provide an acceptable passport photograph,” the department wrote in a document released in response to a freedom of information (FOI) request. “However; the overall performance was judged sufficient to deploy.” Samir Jeraj at the Race Equality Foundation says: “It’s outrageous. It clearly shows it wasn’t a priority for them that it would work for people with black skin.” Jeraj called on the government to be clearer and more robust about what improvements it will make, and by when. In the meantime, he adds it would not cost the passport office anything to put a note on its website acknowledging the issue.

    Most of those under the age of around forty will live lives defined by the anthropocene: by the immense challenges contained in mounting climate chaos and ecological collapse. As these twin calamities evolve, there will be no meaningful way to distinguish between those young generations delineated by marketing agencies: Gen Z and Millennials, the two big generations still under forty. Instead, they will likely become a single transition generation overseeing our move from the old world to a new one. Their shared experiences will be grafted together by the wildfires they’ll weather together, their shared values moulded and alloyed by the acts of violence that have always trailed ecological collapse. The existential crisis inherent to this transition is so dire and so unique that our usual way of demarcating generational cohorts needs revamping, and the generation experiencing it needs a new designation.

  • The big polluters’ masterstroke was to blame the climate crisis on you and me | George Monbiot | Opinion | The Guardian

    the biggest and most successful lie it tells is this: that the first great extermination is a matter of consumer choice. In response to the Guardian’s questions, some of the oil companies argued that they are not responsible for our decisions to use their products. But we are embedded in a system of their creation – a political, economic and physical infrastructure that creates an illusion of choice while, in reality, closing it down. We are guided by an ideology so familiar and pervasive that we do not even recognise it as an ideology. It is called consumerism. It has been crafted with the help of skilful advertisers and marketers, by corporate celebrity culture, and by a media that casts us as the recipients of goods and services rather than the creators of political reality. It is locked in by transport, town planning and energy systems that make good choices all but impossible. It spreads like a stain through political systems, which have been systematically captured by lobbying and campaign finance, until political leaders cease to represent us, and work instead for the pollutocrats who fund them. In such a system, individual choices are lost in the noise. […] This individuation of responsibility, intrinsic to consumerism, blinds us to the real drivers of destruction.

  • Scylla compression benchmarks

    ScyllaDB tested out LZ4, Snappy, DEFLATE, and ZStandard at several different levels on a decently real-world-ish workload. tl;dr:

    Use compression. Unless you are using a really (but REALLY) fast hard drive, using the default compression settings will be even faster than disabling compression, and the space savings are huge. When running a data warehouse where data is mostly being read and only rarely updated, consider using DEFLATE. It provides very good compression ratios while maintaining high decompression speeds; compression can be slower, but that might be unimportant for your workload. If your workload is write-heavy but you really care about saving disk space, consider using ZStandard on level 1. It provides a good middle-ground between LZ4/Snappy and DEFLATE in terms of compression ratios and keeps compression speeds close to LZ4 and Snappy. Be careful however: if you often want to read cold data (from the SSTables on disk, not currently stored in memory, so for example data that was inserted a long time ago), the slower decompression might become a problem.

Not only will an ecologically rich, biodiverse woodland be created, but it also presents opportunities for planting in various environmentally sensitive areas such as Special Areas of Conservation (SACs) and Special Protection Areas (SPAs). Establishing a native woodland will provide you with higher annual payments of €665-€680/ha/yr for 15 years.

  • “See bike, say bike”

    This is useful advice, on how to avoid the SMIDSY, or “Sorry mate, I didn’t see you”, accident type.

    When we looked at what predicts whether you do remember the motorbike, it’s not whether you looked at it, or how long you looked at it for, it’s what you do afterwards. So the more things you look at after the motorbike, the more likely you are to forget it. Now that looks like forgetting, not a failure to attend to it in the first place. […] it looks as though this error is a limitation in short term memory. Now what we do know about short term memory, and we’ve known since the 1960s, is that you’ve got two types of short term memory that are essentially independent systems. You’ve got visuospatial working memory, for the things you look at and you’ve got phonological short term memory. That’s a verbal form of store for things you say. The two are separate. So I’ve suggested that if you’re at a junction and you see a motorbike or a pedal cycle coming, you just say aloud or under your breath, “bike”, that will automatically encode it in phonological working memory. That gives you extra capacity, essentially doubling the amount of stuff you can remember. See bike, say bike could be a simple intervention that might make a big difference.

    Oh christ. This is some terrible logic from Douglas Crockford:

    Comments in JSON (Apr 30, 2012) I removed comments from JSON because I saw people were using them to hold parsing directives, a practice which would have destroyed interoperability. I know that the lack of comments makes some people sad, but it shouldn’t. Suppose you are using JSON to keep configuration files, which you would like to annotate. Go ahead and insert all the comments you like. Then pipe it through JSMin before handing it to your JSON parser.
    I’ve never even _heard_ of JSMin. Meanwhile various tools which chose to use JSON as a configuration file format work around this crappy decision with messy hacks.

  • The Loudest Sound Ever Heard

    The Krakatoa explosion registered 172 decibels at 100 miles from the source. This is so astonishingly loud, that it’s inching up against the limits of what we mean by “sound.” When you hum a note or speak a word, you’re wiggling air molecules back and forth dozens or hundreds of times per second, causing the air pressure to be low in some places and high in other places. The louder the sound, the more intense these wiggles, and the larger the fluctuations in air pressure. But there’s a limit to how loud a sound can get. At some point, the fluctuations in air pressure are so large that the low pressure regions hit zero pressure—a vacuum—and you can’t get any lower than that. This limit happens to be about 194 decibels for a sound in Earth’s atmosphere. Any louder, and the sound is no longer just passing through the air, it’s actually pushing the air along with it, creating a pressurized burst of moving air known as a shock wave.[…] Amazingly, for as many as 5 days after the explosion, weather stations in 50 cities around the globe observed this unprecedented spike in pressure re-occuring like clockwork, approximately every 34 hours. That is roughly how long it takes sound to travel around the entire planet.

  • Scott Aaronson on Google’s quantum supremacy leaked paper

    It seems a paper between Google and NASA accidentally leaked a couple of days ago, saying that a group at Google has now achieved quantum computational supremacy with a 53-qubit superconducting device. According to Scott Aaronson, a noted quantum-computation expert, this is a Big Deal and a significant moment in scientific progress:

    It’s like, have a little respect for the immensity of what we’re talking about here, and for the terrifying engineering that’s needed to make it reality. Before quantum supremacy, by definition, the QC skeptics can all laugh to each other that, for all the billions of dollars spent over 20+ years, still no quantum computer has even once been used to solve any problem faster than your laptop could solve it, or at least not in any way that depended on its being a quantum computer. In a post-quantum-supremacy world, that’s no longer the case. A superposition involving 250 or 260 complex numbers has been computationally harnessed, using time and space resources that are minuscule compared to 250 or 260. I keep bringing up the Wright Flyer only because the chasm between what we’re talking about, and the dismissiveness I’m seeing in some corners of the Internet, is kind of breathtaking to me. It’s like, if you believed that useful air travel was fundamentally impossible, then seeing a dinky wooden propeller plane keep itself aloft wouldn’t refute your belief … but it sure as hell shouldn’t reassure you either.

  • GNOME Foundation facing lawsuit from Rothschild Patent Imaging

    Software patents are a cancer. ‘The GNOME Foundation has been made aware of a lawsuit from Rothschild Patent Imaging, LLC over patent 9,936,086. Rothschild allege that Shotwell, a free and open source personal photo manager infringes this patent. Neil McGovern, Executive Director for the GNOME Foundation says “We have retained legal counsel and intend to vigorously defend against this baseless suit.”’

  • IPCC Report: Oceans Face ‘Unprecedented Conditions’

    The IPCC report on the ocean is full of utterly disastrous science. One example:

    The dangerous changes to the ocean don’t even begin to address the impacts of rising seas. Under all climate change scenarios, coastal areas will see what the report euphemistically calls “extreme sea level events”—that would be floods to you and me—that were once once-in-a-century will become annual occurrences by century’s end. But devastating effects will impact unnumbered people far sooner. “Many low-lying megacities and small islands (including SIDS) are projected to experience historical centennial events at least annually by 2050,” the report authors wrote.
    Bottom line: ‘The world has shown little appetite to take a collaborative approach to these types of adaptation projects let alone drawing down emissions to-date, but the tide will have to turn if humanity is to have any chance of staying above water.’

  • Green New Deal critics are missing the bigger picture

    This Vox article absolutely nails what we are facing, and why there’s no longer any room to _not_ implement a Green New Deal world wide.

    New EPA Administrator Andrew Wheeler recently dismissed the latest IPCC report as being based on a “worst-case scenario,” which is darkly ironic, since the report is all about the dangers that lie between 1.5 and 2 degrees of warming. But 2 degrees is not the worst-case scenario. It is among the best-case scenarios. The UN thinks we’re headed for somewhere around 4 degrees by 2100. Believing that we can limit temperature rise to 2 degrees — a level of warming scientists view as catastrophic — now counts as wild-haired optimism. […] Two degrees would be terrible, but it’s better than three, at which point Southern Europe would be in permanent drought, African droughts would last five years on average, and the areas burned annually by wildfires in the United States could quadruple, or worse, from last year’s million-plus acres. And three degrees is much better than four, at which point six natural disasters could strike a single community simultaneously; the number of climate refugees, already in the millions, could grow tenfold, or 20-fold, or more; and, globally, damages from warming could reach $600?trillion — about double all the wealth that exists in the world today. The worst-case scenario, which, contra Wheeler, is virtually never discussed in polite political circles in the US, is, as Wallace-Wells quotes famed naturalist David Attenborough saying, “the collapse of our civilizations and the extinction of much of the natural world.” That is alarming and, if you must, “alarmist,” but as Wallace-Wells says, “being alarmed is not a sign of being hysterical; when it comes to climate change, being alarmed is what the facts demand.” […] Choosing to continue down our present path is madness. Nihilism. It is not “moderation.”
