No-tipping movement hasn’t gone so well

No-tipping movement hasn’t gone so well

Give workers a living wage! Tipping in restaraunts is wage slavery!

I’ve heard it all out here in Oregon. Calls to unionize restaurants have…been mixed at best. But it turns out, changing restaurant serving work to a ‘living wage’ has largely gone poorly. It turns out the people most upset and leaving restaraunts with no tipping and living wage pay are the workers themselves. A great majority of the restaurants that tried it over the last few years have quietly quit the experiment. Eater magazine, one of the most pro-food restaurant and food worker magazines has written up an excellent article ‘Why the no-tipping restaurant model failed‘. Why would workers leave living wages jobs?

It wasn’t that they didn’t try it or fully embrace the idea. High profile restaurants in San Francisco converted to a no-tipping living wage model – Sons & Daughters, Menlo Park’s Flea Street, Cotogna, Faun, and most famously, Zuni. So did restaurants in New York and other major food destinations. I often ran across restaurants in Portland that gave up tipping in favor of a mandatory living wage surcharge. Since then almost all of them have quietly quit and gone back to tipping – save a few holdouts. Why? The workers left.

It wasn’t just the diners that doomed the movement; workers saw lower earnings were also reluctant to embrace the change. At Faun, for example, Stockwell started servers at $25 per hour when the restaurant was tip-free. Even then, he says, it was “virtually impossible” to compete with what servers could make at a “similarly ambitious local restaurant with tips.” If a tipped server could make $40 to $50 an hour, or up to $350 over the course of a seven-hour shift, why do the same work for half the money?

But it wasn’t just workers. Higher costs do have an impact. A UC Irvine study found that for every dollar increase in food cost, it resulted in more than a 6% decrease in full-service restaurant employment

It’s not like this wasn’t expected. But politicians and activists ignored the simple economics. The wide-spread reality and economics of tipping is right there for politicians. They could have easily found out by checking W-2 reports, well, assuming workers were reporting all their tips ;). The people who were hurt from these experiments in social restructuring and activism are ironically the workers at these restaurants. They were ultimately those that had to change or lost jobs as the predicted lower actual pay and the extra costs drove away customers played out in the economy.

This is not to say that the tipping model is perfect. It certainly is not. But good intentions are NOT enough and certainly not enough to make industry-changing policy. Unintended consequences have very recently been showing the flaws of many poorly designed and implemented overly naïve activist policies.

Other first world countries like Europe and Japan manage to have very affordable food and restaurant experiences in the most expensive cities in the world without trading livability of employees. I have been surprised to find my meals in Paris, London, and Tokyo were often better, and cheaper, than many I have had in the US. Perhaps we should learn more about how their working systems operate instead of letting activist, who rarely have experience or training, legislate policy.

Why Remotes were called clickers

Why Remotes were called clickers

“Pass me the clicker”

My grandfather used to say that when he wanted us to pass him the remote. I never understood why he called it a ‘clicker’. They didn’t click.

But I later found out that they used too.

Here’s a great article on the Zenith Space Command – a remote that didn’t need batteries, infrared, nor even line of sight to the TV. Instead, it worked on sound.

Signs of bitcoin manipulation returning

Signs of bitcoin manipulation returning

Back in 2017, John Griffin, a professor of finance at the University of Texas McCombs School of Business, noticed something strange. They were fascinated to see that a little-known token, Tether, that’s supposed to be backed one-for-one to the dollar was getting printed in large quantities. That clue led the pair to another: When new batches appeared, the price of Bitcoin seemed to jump. It looked like someone, or a group, was using that freshly printed “free money” to inflate Bitcoin’s price for their own profit.

In 2018, they coauthored a groundbreaking study showing that a single, still unidentified, Bitcoin “whale” almost singlehandedly drove the token’s giant run-up in late 2017 and early 2018 by distorting the trading in the token.

He believes it is happening again.

Toward the end of 2022, another mystifying trend caught Griffin’s eye. Despite the crypto crash and myriad other negative forces, every time Bitcoin briefly breached the $16,000 floor, it bounced above that level and kept stubbornly trading between $16,000 and $17,000. Almost unbelievably, as the crypto market has continued to unravel into 2023, Bitcoin has gone in the opposite direction, trading up 35% since Jan. 7 to $23,000.

“It’s very suspicious,” Griffin told Fortune. “The same mechanism we saw in 2017 could be at play now in the still unreal Bitcoin market.”

Update: It’s not like other cryptocurrencies are exhibiting strange behaviors either. Such as a Ether whale that dumped $41M just days before the market crashed.

Packing just got faster and easier

Packing just got faster and easier

MIT has just developed a new computational method that can figure out how to arrange a dense placement of objects inside a rigid container – while also guaranteeing that the objects are separable/interlock free (can be taken out again without getting stuck on each other).

The optimal way of positioning 3D objects of varied sizes and shapes in a container is still considered an unsolved problem. In fact, it is classified as NP-hard, which means it cannot be solved exactly — or even approximately, to a high degree of precision — without gargantuan computational times that could take years or decades depending on the number of pieces that need to be fit into a confined space.

Researchers from MIT and Inkbit (an MIT spinout company in Medford, Massachusetts), headed by Wojciech Matusik, an MIT professor and Inkbit co-founder, is presenting this technique, which they call “Dense, interlocking-free and Scalable Spectral Packing,” or SSP, this August at SIGGRAPH 2023

The method leverages a discrete voxel representation and formulates collisions between objects as correlations of functions computed efficiently using a novel cost function that can be efficiently solved with a Fast Fourier Transform (FFT).

ChatGPT v4 matches top 1% of humans on creativity tests

ChatGPT v4 matches top 1% of humans on creativity tests

Another blow to human superiority?

ChatGPT 4 can already pass the Bar Exam, now it appears to be more creative than humans too. Is this a blow to arguments that computers can’t replace artists?

A University of Montana study used ChatGPT 4 take the Torrance Test of Creative Thinking, a well-known tool used for decades to assess human creativity. They then submitted the AI’s test answers along with the test taken by 24 UM students taking Dr. Erik Guzik’s entrepreneurship and personal finance classes.

These scores were then compared with 2,700 college students nationally who took the TTCT in 2016. All submissions were scored by Scholastic Testing Service, which didn’t know one of the submissions was done by ChatGPT.

The result? The AI’s test answers placed in the top percentile for fluency – the ability to generate a large volume of ideas – and for originality – the ability to come up with new ideas. The AI slipped a bit – to the 97th percentile – for flexibility, the ability to generate different types and categories of ideas.

“For ChatGPT and GPT-4, we showed for the first time that it performs in the top 1% for originality,” Guzik said. “That was new.”

FoxMaster uses a wide variety of AI tools: vision, object recognition, chatgpt, and others to give Laura Croft the AI treatment. She not only can traverse the game, but also has personality and narrates what is going on.

Foxmaster admits some of this is not complete and may be stretched a bit – but his analysis and breakdown of the problems of navigation, identification, and character personality into discrete problems is very interesting.

Nefarious data collection disguised as public art

Nefarious data collection disguised as public art

Beginning early July, mirrored spheres began popping up in cities across the world. It is not public art but a 6.2 pound biometric imaging device designed to scan your eyeballs and capture your irises.

No, it’s not a joke. The company doing this is Worldcoin. Worldcoin was founded three years ago by Alex Blania and Sam Altman, CEO of OpenAI. Their intent is to create “a new identity and financial network connecting billions of people in the age of A.I.” via a privacy-ensuring digital identity it calls World ID and a digital currency, WLD. World ID is supposed to be a ‘perfectly safe’ global identity protocol to enable individuals to prove their personhood online in an era of rampant A.I. deepfakes. WLD is a tool to build an “A.I.-funded UBI [universal basic income]”

This should all sound familiar because they’re the same arguments being made for digital currencies like Bitcoin. The company stresses they have security all along the trust chain, but it reads more like a dystopian nightmare in which everyone has been cataloged and identified by an unknown party with unknown motives. This is a company that could be working for anyone. A 3rd party agent that has unknown motives, unknown technical expertise, and unknown longevity to keep your biometric data safe. You do not really know which government, people, nor company is really behind it all nor what their values nor legal protections you would have. It’s a terrify black box of giving up your biometric data to an almost completely unknown entity. I vote a hard no.

In my opinion, this is a violation of privacy and an extremely bad idea. Even if they are secure today – are they really ready to protect your biometric data, collected surreptitiously, without consent, for all time, and never to sell it? It seems pretty unlikely as every country and every company who has promised this before hasn’t lasted 10 years before being hacked, leaking, being forced to turn over that data, or just flat selling you and your data to the highest bidder when they’re bought out or go bankrupt. Ready for North Korea, China, or Putin to have access to your World ID and any money you put in WLD?

So, maybe be sure to wear some good sunglasses when you find a shiny orb laying on the street.

At least some folks are starting to do an investigation – one I suspect will end badly for Worldcoin considering the EU’s less than open stance on collection/storage of biometric data collection and privacy.
