There are lots of ways to get involved in radio astronomy but they are rarely obvious and do not always offer immediate gratification such as when looking through an optical telescope. Most radio telescope packages involve some construction and software set-up by the user, and that can be time consuming and frustrating especially if there are no clear instructions to guide the amateur. Nonetheless, it is a very rewarding intellectual endeavor to keep you busy to the end of your life. Beginners usually purchase one of the 3 types of radio telescopes, which cost less than $200 each.
then prime minister, John Howard, and his Indigenous affairs minister, Mal Brough, launched the Northern Territory Emergency Response (NTER) into remote Indigenous communities. With no warning, and no consultation, the federal government moved swiftly to seize control of many aspects of the daily lives of residents in 73 targeted remote communities. It implemented coercive measures that would have been unthinkable in non-Indigenous communities. By deploying uniformed members of the Australian Defence Forces into the communities to establish logistics, the Intervention was designed to send a clear message of disruption and control. The government’s suspension of the Racial Discrimination Act raised further cause for concern. Township leases were compulsorily acquired over Aboriginal-owned land by the Commonwealth for a five-year period. And the permit system administered by Aboriginal land councils to control access to Aboriginal land was revoked. Medical teams were flown in to conduct compulsory health checks on children. Signs were posted declaring bans on alcohol and pornography in township areas. Income management was applied to all community residents receiving welfare payments, and income support payments were linked to satisfactory school attendance. The successful Community Development Employment Projects program was abolished, and employees were forced onto unemployment benefits. The police presence was increased in prescribed communities. And customary law was no longer allowed to be considered in bail applications and sentencing in criminal court cases.
To wander through the catacombs is to feel yourself inside of a mystery novel, full of false walls and trapdoors and secret chutes, each leading to another hidden chamber, containing another surprise. Down one passageway, you might find a chamber containing a sprawling Boschian mural that cataphiles had been gradually embellishing for decades; down another, you might see a life-size sculpture of a man half inside a stone wall, as though stepping in from the beyond; down yet another, you might encounter a place that upends your very sense of reality. In 2004, a squadron of cataflics on patrol in the quarries broke through a false wall, entered a large, cavernous space, and blinked in disbelief. It was a movie theater. A group of cataphiles had installed stone-carved seating for twenty people, a large screen, and a projector, along with at least three phone lines. Adjacent to the screening room were a bar, lounge, workshop, and small dining room. Three days later, when the police returned to investigate, they found the equipment dismantled, the space bare, except for a note: “Do not try to find us.”

In a brilliant Twitter thread, UCSB political scientist Matto Mildenberger recounts the sordid history of Garrett Hardin’s classic, widely cited 1968 article “The Tragedy of the Commons,” whose ideas are taught to millions of undergrads, and whose precepts are used to justify the privatization of public goods as the only efficient way to manage them.
Hardin’s paper starts with a history of the English Commons – publicly held lands that were collectively owned and managed – and the claim that commons routinely fell prey to the selfish human impulse to overgraze your livestock on public land (and that even non-selfish people would overgraze their animals because they knew that their more-selfish neighbors would do so even if they didn’t).
But this isn’t what actually happened to the Commons: they were stable and well-managed until other factors (e.g. rich people trying to acquire even more land) destabilized them.
Hardin wasn’t just inventing false histories out of a vacuum. He was, personally, a nasty piece of work: a white supremacist and eugenicist, and the Tragedy of the Commons paper is shot through with this vile ideology, arguing that poor people should not be given charity lest they breed beyond their means (Hardin also campaigned against food aid). Hardin was a director of the Federation for American Immigration Reform and the white nationalist Social Contract Press, and co-founded anti-immigrant groups like Californians for Population Stabilization and The Environmental Fund.
Mildenberger argues that Hardin was a trumpist before Trump: He served on the board of the Federation for American Immigration Reform (FAIR), whose talking points often emerge from Trump’s mouth.
(Hardin quotes that didn’t make it into his seminal paper: “Diversity is the opposite of unity, and unity is a prime requirement for national survival” and “My position is that this idea of a multiethnic society is a disaster…we should restrict immigration for that reason.”)
As Mildenberger points out, this isn’t a case where a terrible person had some great ideas that outlived them: Hardin’s Tragedy of the Commons was a piece of intellectual fraud committed in service to his racist, eugenicist ideology.
What’s worse: the environmental movement elevates Hardin to sainthood, whitewashing his racism and celebrating “The Tragedy of the Commons” as a seminal work of environmental literature. But Hardin is no friend of the environment: his noxious cocktail of racism and false history are used to move public lands into private ownership or stewardship, (literally) paving the way for devastating exploitation of those lands.
By contrast, consider Nobelist Elinor Ostrom’s Governing the Commons, whose groundbreaking insights on the management of common resources are a prescription for a better, more prosperous, more egalitarian future.

A couple of weeks ago, I wrote about GPT-2, a text-generating algorithm whose huge size and long-term analysis abilities mean that it can generate text with an impressive degree of coherence. So impressive, in fact, that its programmers at OpenAI have only released a mini version of the model for now, worried that people may abuse the full-size model’s easy-to-generate, almost-plausibly-human text.
(below: some text generated by mini-GPT-2, in response to the prompt in italics)
This was a fantastic recipe for chocolate cake with raspberry sauce! I only made a couple of changes to the recipe. First, Iadded vanilla candles instead of meringues for a more mild and exotic fragrance. Once again, I only used 1 tsp of vanilla syrup for clarity. Second, the chocolate cake whipped cream was tempered by an additional 1 tsp of canola oil. The regular vegan whipped cream is soothing and makes it pleasing to the hungry healthiest person I know!
In the meantime, as OpenAI had hoped, people are working on ways to automatically detect GPT-2′s text. Using a bot to detect another bot is a strategy that can work pretty well for detecting fake logins, video, or audio. And now, a group from MIT-IBM Watson AI lab and Harvard NLP has come up with a way of detecting fake text, using GPT-2 itself as part of the detection system.
The idea is fairly simple: GPT-2 is better at predicting what a bot will write than what a human will write. So if GPT-2 is great at predicting the next word in a bit of text, that text was probably written by an algorithm - maybe even by GPT-2 itself.
There’s a web demo that they’re calling Giant Language model Test Room (GLTR), so naturally I decided to play with it.
First, here’s some genuine text generated by GPT-2 (the full-size model, thanks to the OpenAI team being kind enough to send me a sample). Green words are ones that GLTR thought were very predictable, yellow and red words are less predictable, and purple words are ones the algorithm definitely didn’t see coming. There are a couple of mild surprises here, but mostly the AI knew what would be generated. Seeing all this green, you’d know this text is probably AI-generated.
Here, on the other hand, is how GLTR analyzed some human-written text, the opening paragraph of the Murderbot diaries. There’s a LOT more purple and red. It found this human writer to be more unpredictable.
But can GLTR detect text generated by another AI, not just text that GPT-2 generates? It turns out it depends. Here’s text generated by another AI, the Washington Post’s Heliograf algorithm that writes up local sports and election results into simple but readable articles. Sure enough, GLTR found Heliograf’s articles to be pretty predictable. Maybe GPT-2 had even read a lot of Heliograf articles during training.
However, here’s what it did with a review of Avengers: Infinity War that I generated using an algorithm Facebook trained on Amazon reviews. It’s not an entirely plausible review, but to GLTR it looks a lot more like the human-written text than the AI-generated text. Plenty of human-written text scores in this range.
And here’s how GLTR rated another Amazon review by that same algorithm. A human might find this review to be a bit suspect, but, again, the AI didn’t score this as bot-written text.
What about an AI that’s really, really bad at generating text? How does that rate? Here’s some output from a neural net I trained to generate Dungeons and Dragons biographies. Whatever GLTR was expecting, it wasn’t fuse efforts and grass tricks.
But I generated that biography with the creativity setting turned up high, so my algorithm was TRYING to be unpredictable. What if I turned the D&D bio generator’s creativity setting very low, so it tries to be predictable instead? Would that make it easier for GLTR to detect? Only slightly. It still looks like unpredictable human-written text to GLTR.
GLTR is still pretty good at detecting text that GPT-2 generates - after all, it’s using GPT-2 itself to do the predictions. So, it’ll be a useful defense against GPT-2 generated spam.
But, if you want to build an AI that can sneak its text past a GPT-2 based detector, try building one that generates laughably incoherent text. Apparently, to GPT-2, that sounds all too human.
A friend of mine who is a very senior cryptographer of longstanding esteem in the field recently changed roles to managing information security for one of the leading machine learning companies: he told me that he thought that it may be that all machine-learning models have lurking adversarial examples and it might be impossible to eliminate these, meaning that any use of machine learning where the owners of the system are trying to do something that someone else wants to prevent might never be secure enough for use in the field – that is, we may never be able to make a self-driving car that can’t be fooled into mistaking a STOP sign for a go-faster sign.
What’s more there are tons of use-cases that seem non-adversarial at first blush, but which have potential adversarial implications further down the line: think of how the machine-learning classifier that reliably diagnoses skin cancer might be fooled by an unethical doctor who wants to generate more billings; or nerfed down by an insurer that wants to avoid paying claims.
The authors propose a taxonomy of attacks, based on whether the attackers are using “white box” or “black box” approaches to the model (that is, whether they are allowed to know how the model works), whether their tampering has to be imperceptible to humans (think of the stop-sign attack – it works best if a human can’t see that the stop sign has been altered), and other factors.
It’s a fascinating paper that tries to make sense of the to-date scattershot adversarial example research. It may be that my cryptographer friend is right about the inevitability of adversarial examples, but this analytical framework goes a long way to helping us understand where the risks are and which defenses can or can’t work.
Until now, Japanese phone carrier Docomo has most often been widelycredited as the originator of what we know as emoji today. It turns out, that might not be the case, and today we are correcting the record.
SoftBank, the carrier that partnered with Apple to bring the iPhone to Japan in 2008, released a phone with support for 90 distinct emoji characters in 1997. For the first time, these are now available on Emojipedia.
Not only was the 1997 SoftBank emoji set released earlier than the first known date of the Docomo emoji set (in “1998 or 1999”), one of the most iconic emoji characters now encoded as 💩 U+1F4A9 PILE OF POO in the Unicode Standard, originated in this release.
Unless or until we find evidence that Docomo had an emoji set available prior to this release, we hereby issue a correction that the original emoji set is from SoftBank in Japan in 1997, with designer/s unknown.

Something I’ve been meaning to say about The Tragedy of the Commons. Bear with me for a small thread on why our embrace of Hardin is a stain on environmentalism. tldr: we’ve let a flawed metaphor by a racist ecologist define environmental thinking for a half century. 1/
Went to a talk last week by someone in the Texas Bureau of Economic Geology & it’s safe to say that many in the oil & gas industry assume something very close to RCP 8.5 (worst-case) emissions scenario for rest of the century. Paris-compatible scenarios were framed as ridiculous.
A summary of Octavia E. Butler’s advice for writers:
1. “Read omnivorously…”
2. “Forget about talent.”
3. “Write, every day, whether you like it or not. Screw inspiration.”
4. “It’s certainly not a matter of sitting there and having things fall from the sky.”
5. “Persist.”

The first population-level study on the link between gut bacteria and mental health identifies specific gut bacteria linked to depression and provides evidence that a wide range of gut bacteria can produce neuroactive compounds. Jeroen Raes (VIB-KU Leuven) and his team published these results today in the scientific journal Nature Microbiology. In their manuscript entitled ‘The neuroactive potential of the human gut microbiota in quality of life and depression’ Jeroen Raes and his team studied the relation between gut bacteria and quality of life and depression. The authors combined faecal microbiome data with general practitioner diagnoses of depression from 1,054 individuals enrolled in the Flemish Gut Flora Project. They identified specific groups of microorganisms that positively or negatively correlated with mental health. The authors found that two bacterial genera, Coprococcus and Dialister, were consistently depleted in individuals with depression, regardless of antidepressant treatment. The results were validated in an independent cohort of 1,063 individuals from the Dutch LifeLinesDEEP cohort and in a cohort of clinically depressed patients at the University Hospitals Leuven, Belgium.
Datashader is a graphics pipeline system for creating meaningful representations of large datasets quickly and flexibly. Datashader breaks the creation of images into a series of explicit steps that allow computations to be done on intermediate representations. This approach allows accurate and effective visualizations to be produced automatically without trial-and-error parameter tuning, and also makes it simple for data scientists to focus on particular data and relationships of interest in a principled way.
