  • Horace Goes Copyright Striking / Boing Boing

    aka “Horace Goes To The Job Centre Because His IP Holder Took A Shit On Literally The Only People Who Give A Fuck About The Character”.

    As of November 14, [Octav1us’] social media channels are deactivated, reportedly to avoid the continuing abuse she receives from anonymous users. For a young woman appropriating the obscure personas of 8-bit British game history, hostility comes in forms both legal and personal. But the message is always the same: stay off the slopes.

  • “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.

  • BBC podcast’s attempt to define ‘shitposting’ leaves viewers baffled

    Laura Keunssberg, the Beeb’s inept political editor, manages to make an utter mess of explaining “shitposting”, claiming it’s analogous to “boomer memes”. Inadvertently this introduces the concept of a “skunked term” — ‘a word that becomes difficult to use because it is in the middle of transitioning from one common meaning to another’.

  • Thomas Talhelm’s DIY air purifier

    Simply strap a HEPA air filter to a desk fan for $30:

    I tested it over and over—hundreds of days, with a control room, with a stronger fan, against the big brand purifiers that I borrowed from my rich friends. Eventually, I saw enough data that I was convinced. This $30 DIY purifier was removing significant amounts of tiny particulate from my Beijing bedroom. I wanted to tell the world that those $1,000 purifiers were ripoffs. I made all the data and testing methods open source. I wrote up the instructions for how to make one.

  • 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.

  • Computer says no: the people trapped in universal credit’s ‘black hole’

    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.

  • Unpopular opinions on solar power

    from Jenny “@solar_chase” Chase. Lots of interesting solar-power factoids, like: 12. A lot of current household PV systems are designed suboptimally and may not make economic sense or even perform well. 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.

  • UK launched passport photo checker it knew would fail with dark skin | New Scientist

    “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.
    And it took a fecking FOI to discover this! Terrible.

  • Gen A

    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. Welcome Generation Anthropocene, or Gen A, to the social scene.

    The top 20 companies on the list have contributed to 35% of all energy-related carbon dioxide and methane worldwide, totalling 480bn tonnes of carbon dioxide equivalent (GtCO2e) since 1965. Those identified range from investor-owned firms – household names such as Chevron, Exxon, BP and Shell – to state-owned companies including Saudi Aramco and Gazprom. Chevron topped the list of the eight investor-owned corporations, followed closely by Exxon, BP and Shell. Together these four global businesses are behind more than 10% of the world’s carbon emissions since 1965.

  • 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.

  • Financial supports to growing forests on farmland in Ireland

    Rather than focusing on the production of a commercial conifer (or broadleaf) timber crop, you can also choose to establish a new native woodland. 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.

  • JSON originally had comments. They were removed

    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.

  • 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.”

  • Neurosexism: the myth that men and women have different brains

    The history of sex-difference research is rife with innumeracy, misinterpretation, publication bias, weak statistical power, inadequate controls and worse. Rippon, a leading voice against the bad neuroscience of sex differences, uncovers so many examples in this ambitious book that she uses a whack-a-mole metaphor to evoke the eternal cycle. A brain study purports to discover a difference between men and women; it is publicized as, ‘At last, the truth!’, taunting political correctness; other researchers expose some hyped extrapolation or fatal design flaw; and, with luck, the faulty claim fades away — until the next post hoc analysis produces another ‘Aha!’ moment and the cycle repeats. As Rippon shows, this hunt for brain differences “has been vigorously pursued down the ages with all the techniques that science could muster”. And it has exploded in the past three decades, since MRI research joined the fray. Yet, as ‘The Gendered Brain’ reveals, conclusive findings about sex-linked brain differences have failed to materialize.

  • Crash Course | The New Republic

    Boeing’s MCAS disaster as a parable of late-stage capitalism:

    [Boeing] engineers devised a software fix called MCAS, which pushed the nose down in response to an obscure set of circumstances in conjunction with the “speed trim system,” which Boeing had devised in the 1980s to smooth takeoffs. Once the 737 MAX materialized as a real-life plane about four years later, however, test pilots discovered new realms in which the plane was more stall-prone than its predecessors. So Boeing modified MCAS to turn down the nose of the plane whenever an angle-of-attack (AOA) sensor detected a stall, regardless of the speed. That involved giving the system more power and removing a safeguard, but not, in any formal or genuine way, running its modifications by the FAA, which might have had reservations with two critical traits of the revamped system: Firstly, that there are two AOA sensors on a 737, but only one, fatefully, was programmed to trigger MCAS. The former Boeing engineer Ludtke and an anonymous whistle-blower interviewed by 60 Minutes Australia both have a simple explanation for this: Any program coded to take data from both sensors would have had to account for the possibility the sensors might disagree with each other and devise a contingency for reconciling the mixed signals. Whatever that contingency, it would have involved some kind of cockpit alert, which would in turn have required additional training—probably not level-D training, but no one wanted to risk that. So the system was programmed to turn the nose down at the feedback of a single (and somewhat flimsy) sensor. And, for still unknown and truly mysterious reasons, it was programmed to nosedive again five seconds later, and again five seconds after that, over and over ad literal nauseam.? And then, just for good measure, a Boeing technical pilot emailed the FAA and casually asked that the reference to the software be deleted from the pilot manual.? So no more than a handful of people in the world knew MCAS even existed before it became infamous. Here, a generation after Boeing’s initial lurch into financialization, was the entirely predictable outcome of the byzantine process by which investment capital becomes completely abstracted from basic protocols of production and oversight: a flight-correction system that was essentially jerry-built to crash a plane. “If you’re looking for an example of late stage capitalism or whatever you want to call it,” said longtime aerospace consultant Richard Aboulafia, “it’s a pretty good one.”?

Fixing echoing sound effects with Huawei Histen

Here’s a quick tip for people using Huawei or Honor phones.

Huawei recently released EMUI version as an OTA update, which I applied once it was offered as an upgrade option.

Once I installed that OS upgrade, however, I noticed that whenever I listened to music or podcasts using a Bluetooth headset or stereo speakers, there was a new and very noticeable ‘echoing’ effect on the audio.

It appears this was due to the addition of Huawei Histen, a 3D audio/equaliser feature, which apparently will add 3D audio effects when listening on wired headphones of various varieties — however this is supposed to be disabled on Bluetooth devices.

I spent several days fruitlessly googling how to disable Histen, but with no luck. Eventually, through trial and error, I discovered a workaround — simply plug in a pair of wired headphones, go into Settings -> Sounds -> Huawei Histen sound effects, and choose “Natural sound”. Hey presto, next time you use Bluetooth headphones, it should no longer have the echo.

  • Facing the Great Reckoning Head-On – danah boyd – Medium

    “Move fast and break things” is an abomination if your goal is to create a healthy society. Taking short-cuts may be financially profitable in the short-term, but the cost to society is too great to be justified. In a healthy society, we accommodate differently abled people through accessibility standards, not because it’s financially prudent but because it’s the right thing to do. In a healthy society, we make certain that the vulnerable amongst us are not harassed into silence because that is not the value behind free speech. In a healthy society, we strategically design to increase social cohesion because binaries are machine logic not human logic.

  • Fairphone 3 Teardown – iFixit

    ‘We tear down the modular Fairphone 3 with a giant grin on our faces! It’s not perfect, but this is just about all we can ask for from a smartphone in 2019.’ Quite nice — modular, reminiscent of the Samsung S5 a little. specs are not stellar, but the ethical construction is a major win IMO. I think this (or the next model if it’s out by then) might be my next phone.

  • Paul Vixie’s answer to “was DNS intentionally designed to be insecure?”

    no. nor ip itself, or ncp which preceded it, or tcp, or udp, or icmp, or smtp, ot http. it was insecure because it evolved in a safe, germ free academic bubble. absolutely none of it was designed with billions of people in mind, or the full cross section of humanity which would include criminals and national intelligence services. the world of the internet in 2019 would have been seen as a total freak show by the community who deployed dns in the 1980’s. nothing that can be abused won’t be. you may or may not believe this; it’s considered controversial, and there are arguments being had about it today. but noone considered that now-controversial near-truism at all when the core internet protocols were first designed and implemented. the idea of abuse was considered novel in the 1990’s when commercialization and privatization brought abuse into the internet world and burst the academic bubble. a lot of old timers blamed AOL and MSN and even Usenet for the problems, but in actuality, it’s what humans _always_ do at scale. putting the full spectrum of human culture atop a technology platform designed for academic and professional culture should have been understood to be a recipe for disaster.

  • Millennium Challenge 2002 – Wikipedia

    omg I never knew about this. Post 9/11, the Bush administration ran a war game scenario which resulted in a massive fail for the US forces, and had to be re-run to ensure they won: ‘At this point, the exercise was suspended, Blue’s ships were “re-floated”, and the rules of engagement were changed; this was later justified by General Peter Pace as follows: “You kill me in the first day and I sit there for the next 13 days doing nothing, or you put me back to life and you get 13 more days’ worth of experiment out of me. Which is a better way to do it?”[1] After the reset, both sides were ordered to follow predetermined plans of action. After the war game was restarted, its participants were forced to follow a script drafted to ensure a Blue Force victory. Among other rules imposed by this script, Red Force was ordered to turn on their anti-aircraft radar in order for them to be destroyed, and was not allowed to shoot down any of the aircraft bringing Blue Force troops ashore.[3] Van Riper also claimed that exercise officials denied him the opportunity to use his own tactics and ideas against Blue Force, and that they also ordered Red Force not to use certain weapons systems against Blue Force and even ordered the location of Red Force units to be revealed.[4]’
