Fish mentality: If The Rock told you to eat flies, would you buy my NFT?

This week's column coming to you via hologram. Or a spaceship

Something for the Weekend How can you tell if a fish is upset? It doesn't grind its pharyngeal teeth, clench its fins or utter moist oaths. And it's not as if you can see tears streaming down its face.

Well, there's an app for that. OK, not an app, at least not yet, but lab boffins at Pacific Northwest National Laboratory have developed a wireless device to not just track where a fish is swimming but also monitor its health and behavior. Miniaturized to about the size of a pen cap, this biotelemetry tag senses everything from heartbeat to tail beat and ambient environmental conditions such as water pressure and (oh yes) magnetic field.

The information gathered by the 2.4g device should help scientists determine what stresses a fish out – climate change, human infrastructure projects, that kind of thing. For example, legislation in many countries insists that migratory species such as salmon are not made too sulky by the introduction of hydropower facilities to want to swim upstream for a bit of piscine nookie.

They're calling it "Lab-on-a-fish." It's essentially a fishy Fitbit.

I wonder if I might borrow one as I think I have upset my neighbor's fish. The neighbor asked me to pop round twice a day while she was away to add some feed, keep its water clean, and check for those subtle telltale signs such as floating upside down immobile at the surface.

I felt sorry for the little fish in its bare tank and so I installed some aquatic furniture that I bought from a pet shop.

I thought a sunken castle, plastic seaweed and a bubbling treasure chest would cheer it up. Instead, the fish is acting kind of… grumpy. I suspect it doesn't like the sudden gentrification of its environment. Perhaps I should have prepared it for the change by introducing a miniature skip and some landscape gardening tools before the subaqueous yuppies moved in.

Lab-on-a-fish already counts tail-flicks (is 10,000 a day the target?) but to be a real fish fitness tracker it should be developed further to record what the fish is eating.

Not that I have ever seen an obese fish reluctant to go on the scales, but what animals feed on can change their behavior. Research by the Milner Centre of Evolution even suggests vegetarian birds are more sociable than insect-eaters.

It's completely the opposite with humans: veggies and vegans are fussy, difficult, and lonely buggers who never get invited to dinner. I should know. Meat-eaters, by contrast, are gregarious and easy to please. So much so that they will eat any old shit if everyone else is eating it, according to yet more research.

The BI Norwegian Business School found that if a celebrity influencer such as Angelina Jolie or Dwayne "The Rock" Johnson endorsed energy bars made of crickets or mealworm burgers, carnivores would follow suit.

According to the study, men were most influenced by famous actors and athletes telling them to eat insects. Women were found to be even more responsive to actors saying it's OK to chomp on creepy-crawlies but totally put off by musicians saying the same thing. Now you know.

Me, if I'm low on protein, I eat some peanuts.

Could a future fish fitness tracker gather enough behavioral data one day to determine whether fish would respond to similar peer pressure? I was going to say that it would be hilarious to imagine what an aquatic-life influencer would look like, but I think I have seen plenty on TikTok already.

Talking of desperate social media marketing and influencers with the mental capacity of a tadpole, you are reading this in the middle of the French presidential election. And it's turning out to be a tech-tastic media blast as the 12 candidates (yes, 12) try to convince voters that they'd metaphorically adore eating dung beetles for breakfast.

The most notable media coverage of the election in terms of IT ignorance so far has been that of left-wing firebrand Jean-Luc Mélenchon's simultaneous appearance as a "hologram" across multiple city venues across France.

"Hologram" – yeah, right. As you have already guessed by looking at the footage above, it's not a hologram, it's the classic Pepper's Ghost illusion in which a moving image is mirrored onto a sheet of glass on stage. It's a nice trick but apart from the digital capture and projection, the technology dates back to 1862.

You'd know if I'd been at one of the "hologram" speeches this week – I'd be the one shouting from the back: "Viva Las Vegas! Do Hound Dog!"

Still, if spittle-spraying Mélenchon's team are calling it a "hologram," everyone follows suit and calls it a "hologram" even when they know it is not. As in "artificial intelligence" (ie, it's not intelligent), "cryptocurrency" (not a currency) and "smart lightbulb" (do you really need me to explain that one?)

More surprising is how everyone missed a trick by not claiming that Melvis was appearing on multiple stages around the country via the metaverse. As a Forrester report pointed out, business decision-makers are running around talking about the metaverse as if it actually existed – which of course it doesn't. But hey, don't let that stop you!

In fact, if you think there is a metaverse and that French presidential candidates are holograms, I have an NFT you might be interested in.

Luxury gift designer Goldgenie is selling NFTs that come with a diamond-encrusted 24k gold iPhone Max 13. The phone is a real phone, albeit with more than a hint of fugly Saddam/Trump chic, but I can't describe what the NFT is for reasons you can work out for yourself. It's selling for $250,000. Don't all rush at once. If only The Rock could demonstrate that it's OK to eat one, eh?

Ah, excuse me, my watch has reminded me it's time to feed the fish. He may be grumpy but he has me well-trained.


Before I go, allow me to add a footnote to say that this week's column marks 10 years of SFTW. A whole decade of this, just imagine! Yes, I know, it seems longer. And it began here. Every column is still on The Reg for your reading displeasure, so as hologrammatic AI Angeline Jolie says, eat them up now.

Thanks for staying faithful, friends.

  • Drone ship carrying yet more drones launches in China
    Zhuhai Cloud will carry 50 flying and diving machines it can control with minimal human assistance

    Chinese academics have christened an ocean research vessel that has a twist: it will sail the seas with a complement of aerial and ocean-going drones and no human crew.

    The Zhu Hai Yun, or Zhuhai Cloud, launched in Guangzhou after a year of construction. The 290-foot-long mothership can hit a top speed of 18 knots (about 20 miles per hour) and will carry 50 flying, surface, and submersible drones that launch and self-recover autonomously. 

    According to this blurb from the shipbuilder behind its construction, the Cloud will also be equipped with a variety of additional observational instruments "which can be deployed in batches in the target sea area, and carry out task-oriented adaptive networking to achieve three-dimensional view of specific targets." Most of the ship is an open deck where flying drones can land and be stored. The ship is also equipped with launch and recovery equipment for its aquatic craft.

  • Experts: AI should be recognized as inventors in patent law
    Plus: Police release deepfake of murdered teen in cold case, and more

    In-brief Governments around the world should pass intellectual property laws that grant rights to AI systems, two academics at the University of New South Wales in Australia argued.

    Alexandra George, and Toby Walsh, professors of law and AI, respectively, believe failing to recognize machines as inventors could have long-lasting impacts on economies and societies. 

    "If courts and governments decide that AI-made inventions cannot be patented, the implications could be huge," they wrote in a comment article published in Nature. "Funders and businesses would be less incentivized to pursue useful research using AI inventors when a return on their investment could be limited. Society could miss out on the development of worthwhile and life-saving inventions."

  • SEC probes Musk for not properly disclosing Twitter stake
    Meanwhile, social network's board rejects resignation of one its directors

    America's financial watchdog is investigating whether Elon Musk adequately disclosed his purchase of Twitter shares last month, just as his bid to take over the social media company hangs in the balance. 

    A letter [PDF] from the SEC addressed to the tech billionaire said he "[did] not appear" to have filed the proper form detailing his 9.2 percent stake in Twitter "required 10 days from the date of acquisition," and asked him to provide more information. Musk's shares made him one of Twitter's largest shareholders. The letter is dated April 4, and was shared this week by the regulator.

    Musk quickly moved to try and buy the whole company outright in a deal initially worth over $44 billion. Musk sold a chunk of his shares in Tesla worth $8.4 billion and bagged another $7.14 billion from investors to help finance the $21 billion he promised to put forward for the deal. The remaining $25.5 billion bill was secured via debt financing by Morgan Stanley, Bank of America, Barclays, and others. But the takeover is not going smoothly.

  • Cloud security unicorn cuts 20% of staff after raising $1.3b
    Time to play blame bingo: Markets? Profits? Too much growth? Russia? Space aliens?

    Cloud security company Lacework has laid off 20 percent of its employees, just months after two record-breaking funding rounds pushed its valuation to $8.3 billion.

    A spokesperson wouldn't confirm the total number of employees affected, though told The Register that the "widely speculated number on Twitter is a significant overestimate."

    The company, as of March, counted more than 1,000 employees, which would push the jobs lost above 200. And the widely reported number on Twitter is about 300 employees. The biz, based in Silicon Valley, was founded in 2015.

  • Talos names eight deadly sins in widely used industrial software
    Entire swaths of gear relies on vulnerability-laden Open Automation Software (OAS)

    A researcher at Cisco's Talos threat intelligence team found eight vulnerabilities in the Open Automation Software (OAS) platform that, if exploited, could enable a bad actor to access a device and run code on a targeted system.

    The OAS platform is widely used by a range of industrial enterprises, essentially facilitating the transfer of data within an IT environment between hardware and software and playing a central role in organizations' industrial Internet of Things (IIoT) efforts. It touches a range of devices, including PLCs and OPCs and IoT devices, as well as custom applications and APIs, databases and edge systems.

    Companies like Volvo, General Dynamics, JBT Aerotech and wind-turbine maker AES are among the users of the OAS platform.

  • Despite global uncertainty, $500m hit doesn't rattle Nvidia execs
    CEO acknowledges impact of war, pandemic but says fundamentals ‘are really good’

    Nvidia is expecting a $500 million hit to its global datacenter and consumer business in the second quarter due to COVID lockdowns in China and Russia's invasion of Ukraine. Despite those and other macroeconomic concerns, executives are still optimistic about future prospects.

    "The full impact and duration of the war in Ukraine and COVID lockdowns in China is difficult to predict. However, the impact of our technology and our market opportunities remain unchanged," said Jensen Huang, Nvidia's CEO and co-founder, during the company's first-quarter earnings call.

    Those two statements might sound a little contradictory, including to some investors, particularly following the stock selloff yesterday after concerns over Russia and China prompted Nvidia to issue lower-than-expected guidance for second-quarter revenue.

  • Another AI supercomputer from HPE: Champollion lands in France
    That's the second in a week following similar system in Munich also aimed at researchers

    HPE is lifting the lid on a new AI supercomputer – the second this week – aimed at building and training larger machine learning models to underpin research.

    Based at HPE's Center of Excellence in Grenoble, France, the new supercomputer is to be named Champollion after the French scholar who made advances in deciphering Egyptian hieroglyphs in the 19th century. It was built in partnership with Nvidia using AMD-based Apollo computer nodes fitted with Nvidia's A100 GPUs.

    Champollion brings together HPC and purpose-built AI technologies to train machine learning models at scale and unlock results faster, HPE said. HPE already provides HPC and AI resources from its Grenoble facilities for customers, and the broader research community to access, and said it plans to provide access to Champollion for scientists and engineers globally to accelerate testing of their AI models and research.
