One of the first things anyone learns about object oriented programming is the power of inheritance and overriding functions. Isn't it great that you can extend or modify the implementation of a function in your derived classes? Don't you wish you could just do that for every function? Aash's co-worker certainly does.

@Override public boolean isEnabled() { if (!super.isEnabled()) { return false; } return true; }

I think this is a beautiful little smear of bad code, because it's useless on multiple levels. First, we are calling a boolean function only to bury it in a conditional which does the exact same thing: return super.isEnabled() would do the job. But if our developer thought to do that, they'd instantly see that there's no point to adding an override- we're just doing what the super class does. The if is just enough to hide that from you if you're careless and not very bright.

And, before you ask, no, there never was any real functionality in this override, at least not that ever got checked into source control. It isn't a vestigial leftover of once useful code. It's just useless from birth.

An anonymous reader quotes a report from The Guardian: When "I can has cheezburger?" became one of the first internet memes to blow our minds, it's unlikely that anyone worried about how much energy it would use up. But research has now found that the vast majority of data stored in the cloud is "dark data", meaning it is used once then never visited again. That means that all the memes and jokes and films that we love to share with friends and family -- from "All your base are belong to us", through Ryan Gosling saying "Hey Girl", to Tim Walz with a piglet -- are out there somewhere, sitting in a datacenter, using up energy. By 2030, the National Grid anticipates that datacenters will account for just under 6% of the UK's total electricity consumption, so tackling junk data is an important part of tackling the climate crisis. Ian Hodgkinson, a professor of strategy at Loughborough University has been studying the climate impact of dark data and how it can be reduced. "I really started a couple of years ago, it was about trying to understand the negative environmental impact that digital data might have," he said. "And at the top of it might be quite an easy question to answer, but it turns out actually, it's a whole lot more complex. But absolutely, data does have a negative environmental impact." He discovered that 68% of data used by companies is never used again, and estimates that personal data tells the same story. [...] One funny meme isn't going to destroy the planet, of course, but the millions stored, unused, in people's camera rolls does have an impact, he explained: "The one picture isn't going to make a drastic impact. But of course, if you maybe go into your own phone and you look at all the legacy pictures that you have, cumulatively, that creates quite a big impression in terms of energy consumption." Since we're paying to store data in the cloud, cloud operators and tech companies have a financial incentive to keep people from deleting junk data, says Hodgkinson. He recommends people send fewer pointless emails and avoid the "dreaded 'reply all' button." "One [figure] that often does the rounds is that for every standard email, that equates to about 4g of carbon. If we then think about the amount of what we mainly call 'legacy data' that we hold, so if we think about all the digital photos that we have, for instance, there will be a cumulative impact."

Slashdot contributors Tablizer, radaos, fjo3, and dbialac highlighted a major discovery by scientists: a reservoir of liquid water hidden deep beneath Mars' rocky outer crust. The BBC reports: The findings come from a new analysis of data from Nasa's Mars Insight Lander, which touched down on the planet back in 2018. The lander carried a seismometer, which recorded four years' of vibrations -- Mars quakes -- from deep inside the Red Planet. Analyzing those quakes -- and exactly how the planet moves -- revealed "seismic signals" of liquid water... The Insight probe was only able to record directly from the crust beneath its feet, but the researchers expect that there will be similar reservoirs across the planet. If that is the case, they estimate that there is enough liquid water on Mars to form a layer across the surface that would be more than half a mile deep. However, they point out, the location of this Martian groundwater is not good news for billionaires with Mars colonization plans who might want to tap into it. "It's sequestered 10-20km deep in the crust," explained Prof Manga. "Drilling a hole 10km deep on Mars -- even for [Elon] Musk -- would be difficult," he told BBC News.

Longtime Slashdot reader schwit1 shares a report from Axios: Locking up merchandise at drugstores and discount retailers hasn't curbed retail theft but is driving frustrated consumers to shop online more, retail experts tell Axios. Retail crime is eating into retailers' profits and high theft rates are also leading to a rise in store closures. Secured cases can cause sales to drop 15% to 25%, Joe Budano, CEO of anti-theft technology company Indyme, previously told Axios. Barricading everything from razors to laundry detergent has largely backfired and broken shopping in America, Bloomberg reports. Aisles full of locked plexiglass cases are common at many CVS and Walgreens stores where consumers have to wait for an employee to unlock them. Target, Walmart, Dollar General and other retailers have also pulled back on self-checkout to deter shoplifting. "Locking up products worsens the shopping experience, and it makes things inconvenient and difficult," GlobalData retail analyst Neil Saunders said, adding it pushes shoppers to other retailers or to move purchases online. Driving the news: Manmohan Mahajan, Walgreens global chief financial officer, said in a June earnings call that the retailer was experiencing "higher levels of shrink." Amazon CEO Andy Jassy spoke of the "speed and ease" of ordering online versus walking into pharmacies on a call with investors last week. "It's a pretty tough experience with how much is locked behind cabinets, where you have to press a button to get somebody to come out and open the cabinets for you," Jassy said. schwit1 adds: "The American-style retail shopping experience was invented in a high-trust environment. As trust erodes, so does the experience."

Google is rolling out a new feature for Google Wallet that uses AI to generate a digital version of IDs, tickets, and other passes. "Replacing the old 'Photo' option, Everything else lets you 'Scan a photo of any pass like an event ticket, gym membership, insurance card, and more' to create a digital version that appears in Google Wallet," writes 9to5Google's Abner Li. "The app explains how AI is leveraged to 'determine what kind of pass you're adding and to suggest the content of the pass.'" From the report: If you're adding something sensitive with health or government ID information, it will be classified as private and not get synced to other devices, while authentication is required before opening. However, you can change the private pass classification later. After taking a picture of the pass, Google will extract the information and let you edit common fields, as well as add your own. At this stage, you can change the pass type [...]. When finalized, it will appear below your carousel of credit/debit cards. Google will let you access the original "Pass photos" when viewing the digital copy.

An anonymous reader quotes a report from the Electronic Frontier Foundation (EFF): In a major decision on Friday, the federal Fifth Circuit Court of Appeals held (PDF) that geofence warrants are "categorically prohibited by the Fourth Amendment." Closely following arguments EFF has made in a number of cases, the court found that geofence warrants constitute the sort of "general, exploratory rummaging" that the drafters of the Fourth Amendment intended to outlaw. EFF applauds this decision because it is essential that every person feels like they can simply take their cell phone out into the world without the fear that they might end up a criminal suspect because their location data was swept up in open-ended digital dragnet. The new Fifth Circuit case, United States v. Smith, involved an armed robbery and assault of a US Postal Service worker at a post office in Mississippi in 2018. After several months of investigation, police had no identifiable suspects, so they obtained a geofence warrant covering a large geographic area around the post office for the hour surrounding the crime. Google responded to the warrant with information on several devices, ultimately leading police to the two defendants. On appeal, the Fifth Circuit reached several important holdings. First, it determined that under the Supreme Court's landmark ruling in Carpenter v. United States, individuals have a reasonable expectation of privacy in the location data implicated by geofence warrants. As a result, the court broke from the Fourth Circuit's deeply flawed decision last month in United States v. Chatrie, noting that although geofence warrants can be more "limited temporally" than the data sought in Carpenter, geofence location data is still highly invasive because it can expose sensitive information about a person's associations and allow police to "follow" them into private spaces. Second, the court found that even though investigators seek warrants for geofence location data, these searches are inherently unconstitutional. As the court noted, geofence warrants require a provider, almost always Google, to search "the entirety" of its reserve of location data "while law enforcement officials have no idea who they are looking for, or whether the search will even turn up a result." Therefore, "the quintessential problem with these warrants is that they never include a specific user to be identified, only a temporal and geographic location where any given user may turn up post-search. That is constitutionally insufficient." Unsurprisingly, however, the court found that in 2018, police could have relied on such a warrant in "good faith," because geofence technology was novel, and police reached out to other agencies with more experience for guidance. This means that the evidence they obtained will not be suppressed in this case.

Over the weekend, former President Donald Trump's campaign said that it had been hacked, with internal documents reportedly obtained illegally by foreign sources to interfere with the 2024 election. While the Trump campaign claimed that Iran was responsible, it is unclear who exactly was behind the incident. The FBI said it was aware of the allegations and confirmed Monday that it is "investigating this matter." The Hill reports: U.S. agencies have thus far failed to comment on the claims that Iran was responsible for the hack, even as recent intelligence community reports have noted growing Iranian efforts to influence the U.S. election. "This is something we've raised for some time, raised concerns that Iranian cyber actors have been seeking to influence elections around the world including those happening in the United States," John Kirby, the White House's national security communications adviser, told reporters Monday. "These latest attempts to interfere in U.S. elections is nothing new for the Iranian regime, which from our vantage point has attempted to undermine democracies for many years now." A report from the Office of the Director of National Intelligence released last month noted Iranian efforts designed to "fuel distrust in U.S. political institutions and increase social discord." "The IC has observed Tehran working to influence the presidential election, probably because Iranian leaders want to avoid an outcome they perceive would increase tensions with the United States. Tehran relies on vast webs of online personas and propaganda mills to spread disinformation," the report states, including being particularly active on exacerbating tensions over the Israel-Gaza conflict.

In an interview with The Verge's Nilay Patel, Replika founder and CEO Eugenia Kuyda discusses the role AI will play in the future of human relationships. Replika is an AI-powered chatbot that offers personalized, empathetic conversations to users, serving as a virtual companion for emotional support, mental health, and social interaction. It allows users to engage in meaningful, human-like conversations, enhancing their well-being through AI-driven companionship. Here is an excerpt from the interview: Where have you landed with Replika now? Is it still sort of romantic? Is it mostly friendly? Have you gotten the user base to stop thinking of it as dating in that way? It's mostly friendship and a long-term one-on-one connection, and that's been the case forever for Replika. That's what our users come for. That's how they find Replika. That's what they do there. They're looking for that connection. My belief is that there will be a lot of flavors of AI. People will have assistants, they will have agents that are helping them at work, and then, at the same time, there will be agents or AIs that are there for you outside of work. People want to spend quality time together, they want to talk to someone, they want to watch TV with someone, they want to play video games with someone, they want to go for walks with someone, and that's what Replika is for. You've said "someone" several times now. Is that how you think of a Replika AI avatar -- as a person? Is it how users think of it? Is it meant to replace a person? It's a virtual being, and I don't think it's meant to replace a person. We're very particular about that. For us, the most important thing is that Replika becomes a complement to your social interactions, not a substitute. The best way to think about it is just like you might a pet dog. That's a separate being, a separate type of relationship, but you don't think that your dog is replacing your human friends. It's just a completely different type of being, a virtual being. Or, at the same time, you can have a therapist, and you're not thinking that a therapist is replacing your human friends. In a way, Replika is just another type of relationship. It's not just like your human friends. It's not just like your therapist. It's something in between those things. With an AI that kind of feels like a person and is meant to complement your friends, the boundaries of that relationship are still pretty fuzzy. In the culture, I don't think we quite understand them. You've been running Replika for a while. Where do you think those boundaries are with an AI companion? I actually think, just like a therapist has agency to fire you, the dog has agency to run away or bite or shit all over your carpet. It's not really that you're getting this subservient, subordinate thing. I think, actually, we're all used to different types of relationships, and we understand these new types of relationships pretty easily. People don't have a lot of confusion that their therapist is not their friend. I mean, some people do project and so on, but at the same time, we understand that, yes, the therapist is there, and he or she is providing this service of listening and being empathetic. That's not because they love you or want to live with you. So we actually already have very different relationships in our lives. We have empathy for hire with therapists, for instance, and we don't think that's weird. AI friends are just another type of that -- a completely different type. People understand boundaries. At the end of the day, it's a work in progress, but I think people understand quickly like, 'Okay, well, that's an AI friend, so I can text or interact with it anytime I want.' But, for example, a real friend is not available 24/7. That boundary is very different. You know these things ahead of time, and that creates a different setup and a different boundary than, say, with your real friend. In the case of a therapist, you know a therapist will not hurt you. They're not meant to hurt you. Replika probably won't disappoint you or leave you. So there's also that. We already have relationships with certain rules that are different from just human friendships. The full transcript can be read here. You can also listen to the interview on the latest episode of Decoder with Nilay Patel.

An anonymous reader quotes a report from Ars Technica: A patent lawsuit filed by one of 3D printing's most established firms against a consumer-focused upstart could have a big impact on the wider 3D-printing scene. In two complaints, (1, 2, PDF) filed in the Eastern District of Texas, Marshall Division, against six entities related to Bambu Lab, Stratasys alleges that Bambu Lab infringed upon 10 patents that it owns, some through subsidiaries like Makerbot (acquired in 2013). Among the patents cited are US9421713B2, "Additive manufacturing method for printing three-dimensional parts with purge towers," and US9592660B2, "Heated build platform and system for three-dimensional printing methods." f There are not many, if any, 3D printers sold to consumers that do not have a heated bed, which prevents the first layers of a model from cooling during printing and potentially shrinking and warping the model. "Purge towers" (or "prime towers" in Bambu's parlance) allow for multicolor printing by providing a place for the filament remaining in a nozzle to be extracted and prevent bleed-over between colors. Stratasys' infringement claims also target some fundamental technologies around force detection and fused deposition modeling (FDM) that, like purge towers, are used by other 3D-printer makers that target entry-level and intermediate 3D-printing enthusiasts.

Civil servants in the UK are locked in a row with the government over plans to use AI to answer taxpayer complaints. The Telegraph: Letters and emails to the Treasury are already being read by an AI tool which summarises the contents and suggests responses for civil servants. The government is now in talks to use AI across more departments, The Telegraph understands. A government spokesman said: "We make no apology for exploring innovations which improve public services. This tool has already been in use for four months and has increased productivity by 30pc, helping us save taxpayers' money by stopping the need to use expensive contractors during busy periods. "Staff at the Treasury will continue to write all public correspondence and make decisions on cases. This tool, which was developed by data science experts in the department, helps civil servants respond to thousands more questions quickly and on time." But the civil serrvice trade body, the Public and Commercial Services (PCS) union, warned that the AI tool could be developed "on the cheap," leading to correspondence being misread. Fran Heathcote, PCS general secretary, said that while the union has no objection in principle to AI, that training the tool "properly takes a long time and considerable resources." Ms Heathcote added: "Further, in anticipation of AI working well, staff numbers are cut so you get the worst of all worlds: a poorly functioning AI system with too few humans left behind to pick up the broken pieces."

In an effort to beef up protections for consumers against corporations, the Biden administration on Monday announced a handful of policies to crack down on "headaches and hassles that waste Americans' time and money." From a report: Through the Federal Trade Commission (FTC) and the Federal Communications Commission (FCC), the administration will ask companies to make it as easy to cancel subscriptions and memberships as it is to sign up for them, and through the Consumer Financial Protection Bureau, a new rule will require companies to let customers cut through automated customer service "doom loops" by pressing a single button to reach a real person. "For a lot of services, it takes one or two clicks on your phone to sign up. It should take one or two clicks on your phone to end the service," White House Domestic Policy Advisor Neera Tanden said on a call with reporters to discuss the new policies. Consumers could see the new rule applied to gym memberships or subscriptions with phone and internet companies. The administration will also call on health insurance companies to allow claims to be submitted online, rather than requiring insured customers to print out and mail forms in for coverage.

St. Cloud State University announced plans to eliminate its music department and cut 42 degree programs and 50 minors, as part of a broader trend of U.S. colleges slashing offerings amid financial pressures. The Minnesota school's decision, driven by a $32 million budget shortfall over two years, reflects challenges facing higher education institutions nationwide. Similar program cuts have been announced at universities across the country, including in North Carolina, Arkansas, and New York. Some smaller institutions have closed entirely, unable to weather the financial storm, reports CBS News. Federal COVID relief funds have dried up, operational costs are rising, and fewer high school graduates are pursuing college degrees. St. Cloud State's enrollment plummeted from 18,300 students in fall 2020 to about 10,000 in fall 2023, mirroring national trends. The National Student Clearinghouse Research Center reports a decline in four-year college enrollment, despite a slight rebound in community college numbers.

An anonymous reader shares a report: Apple recently rejected DOS emulator iDOS 3 from the App Store, but following App Store rule changes that look to have cleared the way for PC emulator apps, iDOS 3 is now available for download, developer Chaoji Li announced. In June, Li said that Apple had rejected iDOS 3 because it violated App Store guideline 4.7. At the time, that rule was what allowed retro game console emulator apps to appear on the store, but Apple was only allowing retro game console emulators under the rule -- not PC emulators; UTM SE, another PC emulator app, had also said it was rejected for violating the rule. But in July, Apple reversed course and approved UTM SE, and earlier this month, it added the words "PC emulator" to guideline 4.7, which is seemingly why iDOS 3 has now been allowed on the App Store.

An anonymous reader shares a report: Once upon a time, you could have yourself a nice little Saturday of stocking up at Costco (using your sister's membership card, naturally), before hitting up a museum (free admission with your 15-year-old expired student ID) or settling into a reality TV binge sesh (streaming on your college roommate's ex-boyfriend's Netflix login). You wouldn't call it stealing, per se. Mooching, perhaps. Exploiting a loophole in a system of commercialized culture you didn't create but are forced to participate in -- and what could be more capitalist than that? But thanks to the fine-tuning of the tech that Corporate America uses to police subscriptions, those freeloading days are over. Costco and Disney this month took a page from the Netflix playbook and announced they are cracking down on account sharers. So the next time you want to restock your Kirkland chocolate covered almond stash, you'll need to have an honest-to-God membership of your own that you scan at the door. Want to put on "Frozen" for the kids so you can have two hours to do literally anything else? You're going to need a Disney+ login associated with your household. The tech that tracks your IP address and can read your face has gotten more sophisticated, and, as the Wall Street Journal reported last week, retailers and streaming services are increasingly turning to status-verification tech that make it harder for folks to claim student discounts on services like Amazon Prime or Spotify beyond graduation.

With its hardware event on Tuesday, Alphabet's Google is trying to outshine Apple's annual iPhone launch -- and is letting longtime executive Rick Osterloh take center stage. Bloomberg: Osterloh, the former president of Motorola who joined Google in 2016, will helm the first major product launch after the company this year unified under his leadership the teams developing hardware and the Android operating system. The reorganization expanded Osterloh's influence in the company and signaled that Google intends to compete in hardware for the long term. In a sign of a more aggressive push into consumer devices, Google moved up its annual flagship Pixel smartphone launch to August from October, preempting the next Apple. iPhone debut and seizing attention during a typically quiet period for the industry. [...] By holding its hardware showcase a month ahead of the iPhone maker's largest annual event, Google is "frontrunning Apple and also making a statement that we are likely way ahead of what Apple will show for iPhone 16 at least," said Mandeep Singh, an analyst with Bloomberg Intelligence. Google has at least a six-month head start on Apple, which has invested less in AI over the years than some of its Big Tech peers, he added. Google's strategy -- tying together the development of hardware, software and services -- carries echoes of Apple's successful approach to designing devices. Yet, as Osterloh seeks to capitalize on the opportunity presented by AI, he faces a perennial challenge for Google: bringing the fight to Apple without threatening key relationships with hardware giants such as Xiaomi that rely on the Android operating system.

For the first time, two new all-electric passenger trains are operating in the US, which is woefully behind the rest of the world in electrifying its rolling stock. The Verge: The two new trains are operated by Caltrain. California Governor Gavin Newson and House Speaker Emerita Nancy Pelosi were on hand to take the inaugural ride, which took place on Saturday. The trains were put into regular service the following day, running along the route between San Jose and San Francisco. It's taken almost 20 years since the idea of electric trains was first proposed in California. But officials insisted the new trains will be quieter and faster than the diesel-powered trains in current operation while also providing a better experience for passengers. The two trains will be joined by 17 others that should be in service by mid-September. [...] It shouldn't come as any shock that the US is lagging behind the rest of the world in introducing electric trains. India is on the cusp of electrifying 100 percent of its rail lines, while China is nearing three-quarters of its network. Over 57 percent of the rail system in the European Union is electric.

Apple has threatened to remove crowdfunding app Patreon from the App Store if creators continue to use unsupported third-party billing options or disable transactions on iOS, instead of using Apple's own in-app purchasing system. From a report: In a blog post and email to Patreon creators about upcoming changes to membership in the iOS app, the company says it's begun a 16-month-long migration process to move all creators to Apple's subscription billing by November 2025. Patreon also informed creators it will switch them over to subscription billing as of November 2024, but they will be able to decide whether to price their memberships at a higher fee to cover Apple's commission or decide if they want to absorb the fee themselves. In addition, creators can opt to delay the migration in their Patreon settings to November 2025, the company said. However, if creators choose the latter option, they won't be able to offer memberships in the iOS app until they adopt Apple's subscription billing, as Apple rules will apply as of this November.

Proximity to natural gas lines could become just as desirable for datacenter operators as high-speed fiber-optic networks as they scramble to satiate AI's ever growing thirst for power. From a report: Speaking to analysts during their respective earnings call this week, executives at Energy Transfer LP and Williams Companies, both of which operate pipelines across the US, revealed they were in talks with datacenter operators to supply them with large quantities of natural gas. "We are, in four different states, in discussions with multiple datacenters of different sizes. Some of them, or many of them, want to put generation on site ... So it's an enormous opportunity for us," Mackie McCrea, co-CEO of Energy Transfer LP, told Wall Street, according to a transcript. Energy Transfer LP's pipelines currently span 15 states in the USA, serving 185 power plants. Looking at the opportunity afforded by datacenter hookups, McCrea estimated that power demand could increase by 30 to 40 gigawatts over the next six to eight years. "We believe we are extremely well positioned to benefit from the anticipated rise in natural gas needs," Energy Transfer LP co-CEO Tom Long added. Energy Transfer LP isn't the only pipeline operator eager to take advantage of skyrocketing datacenter power demands. Speaking to analysts earlier this week, Williams Companies CEO Alan Armstrong expressed optimism about the firm's ability to capitalize on this demand.
