““It is important that we recognise that screens are a modern way of being,” he said. “Reading we see as a hugely positive thing, but it is largely a sedentary thing. We have never done studies to look at the link between reading and adiposity [being overweight] but it is sedentary [lifestyle]. Five hundred years ago we thought it was bad for women’s brains to teach them to read. Reading and pamphlets have radicalised a lot more young people than screens have ever done. Yet we somehow worry about screens being different.””

Trying something inspired by @jeremyzilar idea of unfollowing everybody and rebuilding deliberately.

“Most displays are looking to play things faster. We’ve got movies at 60 frames per second, and gaming displays that run at 144 fps. But what about moving in the other direction? [Bryan Boyer] wanted to try this out, so he built the VSMP, or Very Slow Movie Player. It’s a neat device that plays back a movie at about 24 fph (frames per hour) on an e-ink display to demonstrate something that [Bryan] calls Slow Seeing, which, he says “helps you see yourself against the smear of time.” A traditional epic-length movie is now going to run you greater than 8,000 hours of viewing.“
The belief that a great artist must also be a great (or at least acceptable) person is an infuriatingly stubborn fallacy. My go-to example is composer Richard Wagner, but MMA fighter Jon Jones works just as well. Yes, I know, this isn’t a fight-fan account, but hear me out.

To start this off, I’m pretty sure this post is going to be flagged because I’m using 1 image that I know gets flagged on its own. I do wonder what score this post is going to get though. (Update: this post scores 0.07455623894929886, aka exactly the same as the image below on its own.)
Quick recap if you’ve missed my previous technical musings on the content of flagging and explicit content:
- For each post, tumblr keeps check of a number of variables. One of these is the NSFW score for each post. The score is a value between 0 and 1, and predicts how likely it is that the post is NSFW. for example 0.048 means it has 4.8% probability of being NSFW. In case you wonder, yes that’s enough to get flagged.
- Other variables that are stored on the post are checks if a post is NSFW (yes or no), if a post is NSFW based on the score (yes or no; I’m not sure what the exact difference is, as I’ve only seen them both being no or both being yes), the
classification of the post, and here it’s getting interesting, because a classification of ‘explicit’ means it gets flagged, and ‘clean’ means it won’t get flagged. Easy as that.
Very early this morning I wrote a small tool that lets you see the score and the other variables for the last 10 posts of any user. Instructions are meagre, but the tool is located here.
The above story by Coeur got the following scores:
post type: text
is NSFW based on score: false
is NSFW: false
classification: explicit
score: 0.07757801562547684
As you can see, the score for the post was 0.077…, otherwise known as 7.7% probability that the post is/might contain NSFW content. I did some more testing. First, I copied all the text of the fic, and put it in a new post and had it tested. The score was 0, and classification “clean”. So the text was not the problem. Next I posted the image as both a text post and a photo post for comparison. Both returned the same result: not NSFW, classification explicit and a score of 0.074…
The next step was do a comparison of image moderation tools. I’ve prior experience with Microsoft’s cognitive API, in fact I’ve used it to create a porn blog blocker that would screen new followers and block them if they were a suspected porn blog (unless I was already following them). Here are the scores for several major image moderation providers:
Microsoft cognitive:
“adult”: {
"isAdultContent": false,
"isRacyContent": false,
"adultScore": 0.023388456553220749,
"racyScore": 0.037842851132154465
}
Google Cloud Vision:
“safeSearchAnnotation”: {
"adult": “UNLIKELY”,
"spoof": “POSSIBLE”,
"medical": “UNLIKELY”,
"violence": “UNLIKELY”,
"racy": “LIKELY”
}
Amazon Rekognition failed to find anything in the image that could be suggestive or explicit adult. Since there was nothing found, there weren’t confidence scores given either.
The last one I tested is far less known: it is called
open_nsfw and was actually created by Oath/Yahoo itself, which based on the scores above makes it the most probable to be in use at Tumblr. There is a lot of information not known about it, but here’s a description with references to the paper. I downloaded the model that they released, didn’t fine tune it, and ran it over the above image: NSFW score: 0.02013823203742504
So in conclusion, I have absolutely no clue how Tumblr is able to come up with a score of 0.077 for this image, if the highest score found by other content moderation providers is at 3.7%, barely half of the score tumblr gives it. And that’s not even the actual problem, because this just brings me to the next part.
As I mentioned before, each post gets a couple variable flags for content, including “is_nsfw_based_on_score”. The interesting part here is that this flag appears to only be true, or “yes” if you prefer, when the score is above 0.98. So even when the moderation is 97% certain the image is NSFW, it won’t be flagged as NSFW. However, if your post is only having a score of 0.048… the lowest I’ve seen so far, equaling to 4.8% probability of it being NSFW, it will be flagged as explicit. Keep in mind that the Yahoo paper had the following paragraph:
Our general purpose Caffe deep neural network model (Github code) takes an image as input and outputs a probability (i.e a score between 0-1) which can be used to detect and filter NSFW images. Developers can use this score to filter images below a certain suitable threshold based on a ROC curve for specific use-cases, or use this signal to rank images in search results.
I know that it got pretty technical there, but what they’re saying is that the score on itself is just as-is: a score, a probability. Tumblr’s implementation of the flagging of content however appears to have all content with a score higher than 0 as flagged. I’m not sure if any of you have seen the post about deep learning and unexpected results recently (http://psychopathic-bandaid.tumblr.com/post/180751390174/squiddity3-rubitrightintomyeyes), but tumblr managed to one-up this entire post with the new flagging: Tumblr doesn’t set a threshold, they just decide that if their content moderation says that a post could potentially have a more than 0% chance that content is NSFW, it will flag the post, and that’s it.
Machine learning 101: Even if you’ve created a model that is working pretty decent, you’ve to figure out how to use it. As for tumblr, your model might work decently, the way you use it does not. If content is 90% likely to be NSFW, please flag it as such. If it does not even reach the 30% yeah it’s likely not going to be explicit.
Actual example of a post captioned “caught giving daddy a blowjob”, featuring a single image of a topless woman holding a man’s penis in her hand, the man just wearing a tshirt and socks and that’s it. I got this from an old log file, old meaning September this year, so before the flagging got introduced. As a result I only have the score and NSFW values. The score for this post was 0.92, otherwise known as 92% probability that the post has/is NSFW content. The conclusion with the “is_nsfw” and “is_nsfw_based_on_score” flags was that it was not NSFW. I’ve seen other posts with a score of 0.99 and 1.0 finally getting flagged as NSFW, however, I haven’t seen a single post with a score below 0.98 being marked as NSFW.
Thus concludes this long overview on tumblr’s new flagging system.
Okay Tumblr, here’s a quick way to see if the last 10 posts of any user have been flagged, and if so,
why. If it was for the post being adult content, the NSFW score of a post will be above 0.99 give or take, also known as 99% chance of being NSFW. Below 0.97 is somehow not NSFW, but might still flag a post. If a post gets flagged, the “classification” gets put at “explicit”, otherwise at “clean”. There might be a third option but I haven’t seen that one yet.
The code is ugly, but it’s nearly 5 am and I should get some sleep :P
- Install tampermonkey
- Copy this script and paste it as new script
- Go to https://www.tumblr.com/dashboard and make sure you’re logged in.
- Wait for the page to fully load, type in the blog you want to search for in the search bar and pres the “check flagging scores” button next to the home button. Make sure not to press enter as that will do a search. This was simply the quickest way to code this…
- The score with info will appear in the browser console (if you have xkit enabled after a ton of xkit logging messages)

It started when Tumblr flagged one of my retrospective posts (a five year old post about the right of British schoolkids to opt out of fingerprinting) as porn.
So I made another post, making fun of the pornbot’s shitty judgment. It got flagged.
Undaunted, I made another post complaining about the pornbot’s shitty judgment about its own shitty judgment. Guess what happened?
Naturally, I couldn’t let that slide. YOU WON’T EVER GUESS WHAT HAPPENED NEXT!

The first continuous, multi-century study of surface melt from the Greenland ice sheet was published in Nature Wednesday, and the results are clear: the ice sheet is now melting at rates unseen within at least the last 350 years.
“Melting of the Greenland Ice Sheet has gone into overdrive. As a result, Greenland melt is adding to sea level more than any time during the last three and a half centuries, if not thousands of years,” lead study author and Rowan University School of Earth & Environment glaciologist Luke Trusel said in a press release from the Woods Hole Oceanographic Institution (WHOI), one of the institutions involved in the research.
The researchers found that melting first increased on the ice sheet in the 1800s, when the Arctic began to warm as the process of industrialization started pumping greenhouse gasses into the atmosphere. However, it is only in recent decades that the melting has increased beyond the point of natural variability. There is now 50 percent more meltwater runoff entering the oceans from the sheet since the start of the industrial era, and 30 percent more since the 20th century.
“From a historical perspective, today’s melt rates are off the charts, and this study provides the evidence to prove this,” WHOI glaciologist and study author Sarah Das said.
The researchers were able to prove what many had sensed through observation by using a novel method, as the WHOI explained:
To determine how intensely Greenland ice has melted in past centuries, the research team used a drill the size of a traffic light pole to extract ice cores from the ice sheet itself and an adjacent coastal ice cap, at sites more than 6,000 feet above sea level. The scientists drilled at these elevations to ensure the cores would contain records of past melt intensity, allowing them to extend their records back into the 17th century. During warm summer days in Greenland, melting occurs across much of the ice sheet surface. At lower elevations, where melting is the most intense, meltwater runs off the ice sheet and contributes to sea level rise, but no record of the melt remains. At higher elevations, however, the summer meltwater quickly refreezes from contact with the below-freezing snowpack sitting underneath. This prevents it from escaping the ice sheet in the form of runoff. Instead, it forms distinct icy bands that stack up in layers of densely packed ice over time.
The research is in keeping with estimates that global sea levels will rise by eight to 12 inches by 2050, but University of Lincoln climate scientist Edward Hanna, who was not involved with the study, told InsideClimateNews that sea level rise projections might have to be increased if Greenland keeps melting.
“We can’t rule out that the IPCC (Intergovernmental Panel on Climate Change) sea level rise scenarios are too conservative,” Hanna said. “Greenland is a bit like a sleeping giant that is awakening. Who knows how it will respond to a couple of more degrees of warming? It could lose a lot of mass very quickly.”
Excerpt from this article in the
New York Times Magazine:
When entomologists began noticing and investigating insect declines, they lamented the absence of solid information from the past in which to ground their experiences of the present. “We see a hundred of something, and we think we’re fine,” Wagner says, “but what if there were 100,000 two generations ago?” Rob Dunn, an ecologist at North Carolina State University who helped design the net experiment in Denmark, recently searched for studies showing the effect of pesticide spraying on the quantity of insects living in nearby forests. He was surprised to find that no such studies existed. “We ignored really basic questions,” he said. “It feels like we’ve dropped the ball in some giant collective way.”
If entomologists lacked data, what they did have were some very worrying clues. Along with the impression that they were seeing fewer bugs in their own jars and nets while out doing experiments — a windshield phenomenon specific to the sorts of people who have bug jars and nets — there were documented downward slides of well-studied bugs, including various kinds of bees, moths, butterflies and beetles. In Britain, as many as 30 to 60 percent of species were found to have diminishing ranges. Larger trends were harder to pin down, though a 2014 review in Science tried to quantify these declines by synthesizing the findings of existing studies and found that a majority of monitored species were declining, on average by 45 percent.
Entomologists also knew that climate change and the overall degradation of global habitat are bad news for biodiversity in general, and that insects are dealing with the particular challenges posed by herbicides and pesticides, along with the effects of losing meadows, forests and even weedy patches to the relentless expansion of human spaces. There were studies of other, better-understood species that suggested that the insects associated with them might be declining, too. People who studied fish found that the fish had fewer mayflies to eat. Ornithologists kept finding that birds that rely on insects for food were in trouble: eight in 10 partridges gone from French farmlands; 50 and 80 percent drops, respectively, for nightingales and turtledoves. Half of all farmland birds in Europe disappeared in just three decades. At first, many scientists assumed the familiar culprit of habitat destruction was at work, but then they began to wonder if the birds might simply be starving. In Denmark, an ornithologist named Anders Tottrup was the one who came up with the idea of turning cars into insect trackers for the windshield-effect study after he noticed that rollers, little owls, Eurasian hobbies and bee-eaters — all birds that subsist on large insects such as beetles and dragonflies — had abruptly disappeared from the landscape.
Scientists have tried to calculate the benefits that insects provide simply by going about their business in large numbers. Trillions of bugs flitting from flower to flower pollinate some three-quarters of our food crops, a service worth as much as $500 billion every year. (This doesn’t count the 80 percent of wild flowering plants, the foundation blocks of life everywhere, that rely on insects for pollination.) If monetary calculations like that sound strange, consider the Maoxian Valley in China, where shortages of insect pollinators have led farmers to hire human workers, at a cost of up to $19 per worker per day, to replace bees. Each person covers five to 10 trees a day, pollinating apple blossoms by hand.
By eating and being eaten, insects turn plants into protein and power the growth of all the uncountable species — including freshwater fish and a majority of birds — that rely on them for food, not to mention all the creatures that eat those creatures. We worry about saving the grizzly bear, says the insect ecologist Scott Hoffman Black, but where is the grizzly without the bee that pollinates the berries it eats or the flies that sustain baby salmon? Where, for that matter, are we?
Remember when Malcolm Turnbull, the goddamned idiot who was briefly Prime Minister of Australia, was told that the laws of mathematics mean that there was no way to make a cryptography system that was weak enough that the cops could use to spy on bad guys, but strong enough that the bad guys couldn’t use it to spy on cops, and he said: “Well the laws of Australia prevail in Australia, I can assure you of that. The laws of mathematics are very commendable, but the only law that applies in Australia is the law of Australia.”
He added: “I’m not a cryptographer, but what we are seeking to do is to secure their assistance. They have to face up to their responsibility. They can’t just wash their hands of it and say it’s got nothing to do with them.”
Malcolm Turnbull lost his job, though not for saying this goddamned idiotic thing. This goddamned idiotic thing has continued to fester in Australian politics, until today, when the pustule ruptured and Parliament sat down and voted to make the laws of Australia prevail over the laws of mathematics.
Good luck with that.
Under the new rule, cops can get court orders that will require tech companies to backdoor their encryption, serve malware, or do whatever else it takes to decrypt subjects’ messages, even if those messages are so well encrypted that it would take more computational cycles than can be wrung out of all the matter in the universe to brute-force the key.
Bad guys, meanwhile, can just use free/open source software, or tools that are made by companies located outside of Australia, or tools that exist today without any backdoors, and never fear police interception.
Making this bill work would mean a raft of extreme measures: seizing and altering every general purpose computer in Australia; banning the importation of any computing device, including phones and laptops, into Australia; blocking Github and every other software distribution site at the national level, and more.

The European Union is at risk of missing a historic opportunity to bring the right to repair into legislation for the first time.
From Monday 10 December all EU member states will be called to vote on a package of regulations requiring manufacturers to make consumer and industrial products more repairable and energy-efficient in order to be approved in the EU single market.
However, pressure from industry lobbying, especially in key countries with a big manufacturing sector like Germany, Italy and the UK, has severely reduced the repair provisions in the proposed legislation. The latest draft lacks ambition and significantly limits the potential to make repairing appliances easier for all.
Luckily, all is not lost. We (The Restart Project) are urging everyone to support citizen-driven campaigning, which is proving fruitful in some of the key countries opposing the regulation. A German petition promoted by repair activists has created a real stir, garnering over 109,000 signatures and resulting in the Ministry of Environment releasing an action plan stating its full support for repair provisions. And in Italy, a petition demanding that the country stops blocking promising regulation has reached over 76,000 signatures and will be handed over to the Minister of Environment this week by community repair group Restarters Milano. But in the UK a similar petition has been overshadowed by Brexit negotiations. Meanwhile local community repair activists have come up with the Manchester Declaration, calling for more repairable products.
Citizens want longer lasting and easier to repair products and they get frustrated when things break much earlier than they should. There is fresh evidence that people want these changes, and specifically want governments to take an active role, as documented in recently published research by the Green Alliance in the UK and the EU Commission.
Why are these votes so important? For the first time these so-called “ecodesign” regulations take into account a product’s material efficiency over its whole lifecycle, not just the use phase. The new measures acknowledge that a huge amount of a product’s environmental impact comes from manufacturing. This means that being able to repair products is vital to extending their longevity and preventing unnecessary waste. It is estimated that with the new measures in place, by 2030 Europe alone could be saving 140 TWh of energy a year, 5% of its entire energy consumption.
So far attention on right to repair legislation has been mostly concentrated on the United States, with a focus on state-level measures to remove barriers for independent repairers to do their work. Yet it is now at the European Union level that we stand a chance to impact right to repair globally.
While the proposed measures only focus on repairability for appliances such as fridges, washing machines and dishwashers, this create a precedent, strongly increasing the odds that right to repair becomes a central aspect of future regulation for computers, vacuum cleaners and smartphones. Also, these measures are likely to trigger the emergence of similar requirements elsewhere around the world.
What makes a product repairable? In September the EU Commission drafted laws focusing on a few key issues: requiring availability for spare parts for a minimum number of years as well as access to repair information resources and, crucially, improving design to access key components in household appliances. As a result, repairing products could become easier, cheaper and less time-consuming.
This is in line with the demands of the emerging community repair movement, as reflected in initiatives like the Open Repair Alliance’s International Repair Day. However, the latest revision of the proposals reflects the language and the demands of the industry, as summarised by a briefing of the European Environmental Board.
For example, rather than providing free access to repair information for all, the regulation could restrict access to registered, professional repairers who pay the manufacturers a fee, thus slamming the door on, among others, the growing movement of community repair initiatives. Also, appliance manufacturers wouldn’t be required to supply spare parts to third parties for the first two years from the introduction of a new model, potentially giving them initial complete control over repairs happening within the warranty period (even when not covered by warranty). Finally, the laudable initial inclusion of design requirements to simplify disassembly of appliances for repair is at risk of being replaced with a focus on effective dismantling for recycling at the end of life.
The ball is now in the member states’ court. Will they show some ambition and push for measures that will benefit all of their citizens, while contributing to creating local repair jobs and reducing the imbalance of power with manufacturers? Or will they bow to industry pressure and miss this rare chance for the European Union to demonstrate that it can lead the way in pushing for better standards for all?

Reliability engineering is the technical discipline of estimating, controlling and managing theprobability of failure in devices, equipment and systems. Design principles and tools which should be utilized by the designer include
(1) Part Selection and Control
(2) Part Derating
(3) Reliable Circuit Design
(4) Redundancy
(5) Environmental Design
(6) Human Factors Design
(7) Failure Modes, Effects and Criticality Analysis (FMECA)
(8) Fault Tree Analysis (FTA)
(9) Sneak Circuit Analysis
(10) Design Reviews
Items (1) and (2) are addressed in Section 7 largely by reference to MIL-HDBK- 338, Volume II.
Discussion of reliable circuit design includes design simplification, use of standard circuits, transient and overstress protection, parameter degradation and analysis, minimizing design errors and fundamental design limitations. Redundancy techniques addressed include simple parallel, bimodal, majority vote and standby, plus examples of redundant systems used in sophisticated aircraft and space vehicles. Appendix A to Section 7 gives multiple examples of these techniques.
Designing for the environment considers measures of protection against high and low temperatures, shock and vibration, moisture, sand and dust, explosion, electromagnetic and nuclear radiation. Table 14.1 demonstrates the relationship among stresses, their effects, andreliability improvement techniques. Appendix B to Section 7 details environmental effects, including air-launched weapon environmental criteria.
Discussion of human factors active in the design of electronic equipment addresses the motor responses and physical capabilities of operators, human performance reliability, the relationship
between human factors and reliability, the three factors affecting human behavior, i.e., stimulus- input (S), internal reaction (0) and output response ®, and man-machine interaction and trade- offs.
Failure Modes, Effects and Criticality Analysis (FMECA) is discussed in detail which includes a step-by-step procedure, demonstration requirements, failure mode distribution, determination ofcriticality, use of computer analysis and its limitations. Note: FMECA is also addressed in Chapter 12.0 of this Primer.
Fault Tree Analysis (FTA) the “top-down” corollary to the FMEA “bottom-up” reliability risk analysis technique is thoroughly investigated. Step-by-step procedures for the performance of an FTA are detailed, including the three basic methods for solving fault trees, i.e., (1) direct simulation (2) Monte Carlo and (3) direct analysis.
A sneak circuit is defined as an unexpected path or logic flow within a system, which, under certain conditions, can initiate an undesired function or inhibit a desired function. Sneak Circuit Analysis (SCA) is the term applied to analytical techniques used to detect and identify sneak circuits in a system. The point is made that unlike other reliability analyses, SCA concentrates onthe interconnections, interrelationships and interactions of system components rather than the components themselves….
