Comment We tried and failed years ago (Score 4, Insightful) 55

More than 10 years ago, my company tried to do facial recognition in an airport in Europe, for their security service. Alas, they didn't know about the "birthday paradox", and tried to match about 1,000 criminals against several thousand passengers. They shut it down when the system identified someone's grandmother as a male member of the Baader-Meinhof gang.

The (birthday) paradox is caused by trying to match each passenger against 1,000 criminals, not just one. Even with only a 1% error rate, there will be 10 false positives and negatives per passenger. And we don't have anything like a 1% error rate.

We need a 1/infinity error rate (:-)) Otherwise innocent grandmothers will be pulled aside, while actual criminals will breeze on through.

Alas, HR departments will wonder why they're getting fewer and fewer applications. Only if hiring manager need to sign off on ads for their positions will one have a good chance of getting a valid skills list and job description.

My company used to own a headhunter. We had to have a co-op student train them on AND and OR before we dared use them for our own job postings. Their training doesn't prepare them for hiring people with skills.

Previous folks announced they had AI, talking about
- rule-based systems written in lisp and prolog
- machine-learning systems written in math and stats
- large language learning-models written in harder-to-evaluate math

All but the last was massively different from the previous.

I'll therefor be waiting to see another massive change before I believe they've made an advance toward AGI. Right now they're at MachineLearning++ running on ArrayProce$$or$++.

Consider a few examples of successful forks:

  • - LibreOffice -formerly OpenOffice, formerly StarOffice
  • - OpenStreetMap -growing Google Maps replacement
  • - OpenTofu - fork of Terraform
  • - KeyDB - Redis alternative
  • - OpenSearch (AWS-backed) - Elasticsearch alternative

The scholarly publishing ecosystem runs largely on unpaid academic labour. Give that, I wonder if a university press or three should pick up the task of publishing academic journals, and incidentally using some of those profits to improve the journal's quality. By paying editors.

Submission + - Companies Issuing RTO Mandates 'Lose Their Best Talent': Study (arstechnica.com)

An anonymous reader writes: Return-to-office (RTO) mandates have caused companies to lose some of their best workers, a study tracking over 3 million workers at 54 "high-tech and financial" firms at the S&P 500 index has found. These companies also have greater challenges finding new talent, the report concluded. The paper, Return-to-Office Mandates and Brain Drain [PDF], comes from researchers from the University of Pittsburgh, as well as Baylor University, The Chinese University of Hong Kong, and Cheung Kong Graduate School of Business. The study, which was published in November, spotted this month by human resources (HR) publication HR Dive, and cites Ars Technica reporting, was conducted by collecting information on RTO announcements and sourcing data from LinkedIn.

The researchers said they only examined companies with data available for at least two quarters before and after they issued RTO mandates. The researchers explained: "To collect employee turnover data, we follow prior literature ... and obtain the employment history information of over 3 million employees of the 54 RTO firms from Revelio Labs, a leading data provider that extracts information from employee LinkedIn profiles. We manually identify employees who left a firm during each period, then calculate the firm’s turnover rate by dividing the number of departing employees by the total employee headcount at the beginning of the period. We also obtain information about employees’ gender, seniority, and the number of skills listed on their individual LinkedIn profiles, which serves as a proxy for employees’ skill level."

There are limits to the study, however. The researchers noted that the study "cannot draw causal inferences based on our setting." Further, smaller firms and firms outside of the high-tech and financial industries may show different results. Although not mentioned in the report, relying on data from a social media platform could also yield inaccuracies, and the number of skills listed on a LinkedIn profile may not accurately depict a worker's skill level. [...] The researchers concluded that the average turnover rates for firms increased by 14 percent after issuing return-to-office policies. "We expect the effect of RTO mandates on employee turnover to be even higher for other firms" the paper says.

Submission + - Nuclear-diamond battery could power devices for 1000s of years. (livescience.com) 1

fahrbot-bot writes: Live Science has a report about the world's first nuclear-diamond battery using carbon-14, which has a half-life of 5,700 years, to power devices.

The nuclear battery uses the reaction of a diamond placed close to a radioactive source to spontaneously produce electricity, scientists at the University of Bristol in the U.K. explained in a Dec. 4 statement. No motion — neither linear nor rotational — is required. That means no energy is needed to move a magnet through a coil or to turn an armature within a magnetic field to produce electric current, as is required in conventional power sources.

The diamond battery harvests fast-moving electrons excited by radiation, similar to how solar power uses photovoltaic cells to convert photons into electricity, the scientists said.

The researchers chose carbon-14 as the source material because it emits short-range radiation, which is quickly absorbed by any solid material — meaning there are no concerns about harm from the radiation. In addition, while carbon-14 is extremely toxic to touch or ingest, the surrounding diamond also provides maximal protection.

A single nuclear-diamond battery containing 0.04 ounce (1 gram) of carbon-14 could deliver 15 joules of electricity per day. For comparison, a standard alkaline AA battery, which weighs about 0.7 ounces (20 grams), has an energy-storage rating of 700 joules per gram. It delivers more power than the nuclear-diamond battery would in the short term, but it would be exhausted within 24 hours.

By contrast, the half-life of carbon-14 is 5,730 years, which means the battery would take that long to be depleted to 50% power. This is close to the age of the world's oldest civilization. As another point of comparison, a spacecraft powered by a carbon-14 diamond battery would reach Alpha Centauri — our nearest stellar neighbor, which is about 4.4 light-years from Earth — long before its power were significantly depleted.

The battery, which was built on a plasma deposition rig near Abingdon, Oxfordshire, in the U.K. by a team from the University of Bristol and the U.K. Atomic Energy Authority (UKAEA), has no moving parts and thus requires no maintenance, nor does it have any carbon emissions.

Submission + - Boeing to take more than a decade to refit two 747s for Air Force One (behindtheblack.com)

schwit1 writes: Utter incompetence: According to recent news reports, Boeing will not be able to deliver the two 747s it is refitting to be the president's Air Force One fleet until 2029, even though it signed a $3.9 billion contract to do so in 2018.

The delay is startling given that Boeing isn’t building the planes from scratch. During Trump’s first term, Boeing started to overhaul two 747s that were built for a Russian airline that never took the jets.

This is more than absurd, it is obscene. Boeing is handed two flightworthy 747s and almost $4 billion, and it can't refit the two planes in less than a decade? It seems one of the first things Trump should do once he returns to office next month is cancel this contract entirely, demand a refund from Boeing, and simply convert his present fleet of "Trump Force One" airplanes that he has been using since 2020 for use as president. Cheaper, faster, and certainly a wiser use of taxpayer money.

As for Boeing, this story illustrates once again how far this company has fallen. Remember, it was Boeing that conceived, designed, and built the 747. Moreover, its 747 has been used for decades for Air Force One. For its engineers now to be incapable to refitting another two 747s for this purpose seems inconceivable, and suggests those same engineers should not be trusted on any new planes they build.

Submission + - AT&T to kill off landline phone service for most people by 2029 (zdnet.com)

SonicSpike writes: AT&T customers who still use the carrier's landline service should be prepared to say goodbye sometime in the next five years.

At its 2024 Analysts and Investors Day on Wednesday, the company said that it's "actively working to exit its legacy copper network operations across the large majority of its wireline footprint by the end of 2029." Yep, that means its traditional landlines will largely be gone by that point, at least if the roadmap comes true.

Like many carriers, AT&T has devoted more of its time, money, and resources to its broadband network and wireless services. AT&T in particular has focused on building out its fiber network, which it forecasts will expand to more than 50 million locations in the US by the end of 2029.

The problem with copper lines, argue the carriers, is that they're old, vulnerable to power surges and other electrical issues, and subject to damage from weather and other conditions. Plus, companies like AT&T simply don't want to support traditional landlines when so many people have switched to mobile or broadband services.

He had been accused of using artificial intelligence to complete a piece of assessed work. If he did not attend a hearing to address the claims made by his professor, or respond to the email, he would receive an automatic fail on the module. The problem was, he hadn’t cheated...'

'There is also evidence that suggests AI detection tools disadvantage certain demographics. One study at Stanford found that a number of AI detectors have a bias towards non-English speakers, flagging their work 61% of the time, as opposed to 5% of native English speakers (Turnitin was not part of this particular study). Last month, Bloomberg Businessweek reported the case of a student with autism spectrum disorder whose work had been falsely flagged by a detection tool as being written by AI.'

'Many academics seem to believe that “you can always tell” if an assignment was written by an AI, that they can pick up on the stylistic traits associated with these tools. Evidence is mounting to suggest they may be overestimating their ability. Researchers at the University of Reading recently conducted a blind test in which ChatGPT-written answers were submitted through the university’s own examination system: 94% of the AI submissions went undetected and received higher scores than those submitted by the humans.'

'The AI cheating crisis has exposed how transactional the process of gaining a degree has become. Higher education is increasingly marketised; universities are cash-strapped, chasing customers at the expense of quality learning.'
