Why Chains Are Still Better For Bicycles Than Belts

Published

on

Theoretically a belt drive makes for a great upgrade to a bicycle, as it replaces the heavier, noisy and relatively maintenance-heavy roller chain with a zero-maintenance, whisper-quiet and extremely reliable belt that’s rated at an amazing 20-30,000 km before needing a replacement. Of course, that’s the glossy marketing brochure version of reality, which differed significantly from what [Tristan Ridley] experienced whilst cycling around the globe.

Although initially he was rather happy with his bike, its sealed car-like Pinion gearbox and Gates carbon belt drive system, while out in the wilds of Utah he had a breakdown when the belt snapped. When the spare belt that he had carried with him for the past months also snapped minutes later after fitting it on, it made him decide to switch back to the traditional bush roller chain.

Despite this type of chain drive tracing its roots all the way back to Leonardo da Vinci, they actually offer many advantages over the fancy carbon-fiber-reinforced polyurethane belt. Although with the Pinion gearbox the inability to use a derailleur gearing system is no big deal, [Tristan] found that the ‘zero maintenance’ part of the belt was not true for less hospitable roads

A big issue was that of abrasive dust, which created a very noisy coating on the belt that’d have to be regularly cleaned off with precious water, or by having silicone lubricant sprayed on the belt. Even with all that care he found that the belt would snap after about 8,000 km, well below the rated endurance.

When it came to super-sticky mud, called peanut butter mud for good reasons, he found that chains also cope much better with this, as the mud will just squeeze out of the chain and be forced off the sprocket, whereas the belt will happily keep compacting the mud onto the contact surfaces, increasing belt tension and requiring constant cleaning to not become hopelessly stuck.

The Utah breakdown also showed why these belts are actually very fragile: the replacement belt had been packed away folded-up for a few months at that point in the luggage, and during storage the carbon fibers had become compromised to the point where the belt just snapped after a few minutes of use. A metal chain will happily be stored away for as long as you can keep it away from corrosion, and fold up very compactly.

Another awesome feature of roller chains is that they’re super-modular, allowing you to carry spare links and such with you for in-the-field repairs, while even the most remote bicycle store in any country can help you out with maintenance and repairs, unlike the special and highly custom belts that need to be shipped in by courier.

Of all the bicycle technologies that [Tristan] has used, it seems that only this drive belt has been an outright disappointment. The sealed gearbox would seem to be a massive improvement over finicky derailleurs, and hydraulic brakes are reliable and common enough that they haven’t been an issue so far.

His conclusion is that bicycle drive belts are fine if you do city driving, where they probably will last the rated kilometers, but they rapidly fall apart in even slightly adverse conditions.

OpenAI will reportedly release an AI-powered smart speaker in 2027

Published

on

OpenAI is reportedly hard at work developing a series of AI-powered devices, including smart glasses, a smart speaker and a smart lamp. According to reporting by , the AI company has a team of over 200 employees dedicated to the project.

The first product scheduled to be released is reported to be a smart speaker that would include a camera, allowing it to better absorb information about its users and surroundings. According to a person familiar with the project, this would extend to identifying objects on a nearby table, as well as conversations being held in the vicinity of the speaker. The camera will also support a facial recognition feature similar to Apple’s Face ID that would enable users to authenticate purchases.

The speaker is expected to retail for between $200 and $300 and ship in early 2027 at the earliest. Reporting indicates the company’s AI-powered smart glasses, a space currently dominated by , would not come until 2028. As for the smart lamp, while prototypes have been made, it’s unclear whether it will actually be brought to market.

Last year OpenAI ex-Apple designer Jony Ive’s startup io Products for $6.5 billion. Ive is considered largely responsible for Apple’s design aesthetic, having been involved in designing just about every major Apple device since joining the company in the ’90s before his departure in 2019. The acquisition of his sets the stage for Ive to lead hardware product development now for OpenAI.

Since the partnership was forged, there have already due to technical issues, privacy concerns and logistical issues surrounding the computing power necessary to run a mass-produced AI device. Regardless of the behemoths behind the project, the speaker and other future products may still face a consumer that is always listening to and watching its users.

A Galaxy Composed Almost Entirely of Dark Matter Has Been Confirmed

Published

on

Astronomers have just identified what appears to be a cosmic anomaly: a faint galaxy with so few visible stars that, according to calculations, as much as 99.9 percent of its mass is dark matter. The remaining 0.1 percent is conventional matter.

This galaxy, located about 300 million light-years away, is practically invisible. Only four globular clusters, small concentrations of stars that look like isolated neighborhoods in the middle of the void, stand out. For years, these star collections in the Perseus cluster were considered independent objects.

Cúmulos globulares en el Cúmulo de Perseo.

Candidate Dark Galaxy-2 is only visible through four globular clusters that contribute to 16 percent of its total brightness. Scientists believe 99.9 percent of this galaxy is dark matter.

NASA/ESA

Now, after an exhaustive analysis, a study published in The Astrophysical Journal Letters presents solid evidence that these globular clusters are part of the same galaxy dominated by dark matter. Tentatively named CDG-2 (Candidate Dark Galaxy-2), it is the first galaxy to be detected only by its brightest fragments.

The authors pooled data from the Hubble, Euclid, and Subaru telescopes, three of the most powerful observatories available. The combined readings reveal an extremely faint glow around the four globular clusters. This residual light is a clear sign of an underlying galaxy so dim that the three telescopes missed it on their own.

More Than Meets the Eye

Preliminary analysis indicates that CDG-2 has a total luminosity equivalent to about 6 million suns, with the four globular clusters contributing about 16 percent of that brightness, an unusually large share. This distribution suggests that, despite its low light, the galaxy is a gravitationally bound system, implying a particularly dense dark matter halo. Astronomers estimate that this invisible structure accounts for between 99.94 to 99.98 percent of CDG-2’s total mass.

According to current models, dark matter constitutes roughly 27 percent of the universe’s total energy density and about 85 percent of its matter. Although the exact nature of what makes up dark matter is still unclear, because it neither emits nor reflects light, scientists infer its existence from its gravitational effects on radiation, visible matter, and the large-scale structure of the cosmos.

Dark matter is so pervasive throughout galaxies that its presence explains the stability and motion of stars in systems such as the Milky Way. For example, current models indicate that our galaxy is embedded in a halo composed of about 90 percent dark matter.

However, the case of CDG-2 is extreme: a galaxy with almost no stars, surrounded almost entirely by an invisible halo. These types of systems, so-called “dark galaxies,” are beginning to appear in astronomical records. Beyond their rarity, scientists value them because they serve as natural laboratories for exploring the nature of dark matter and testing current models of galaxy formation.

‘Narco-Submarine’ Carrying 4 Tons of Cocaine Captured by Mexico’s Navy

Published

on

The Mexican Navy announced on Thursday that it had seized a semi-submersible vessel carrying nearly four tons of cocaine. The seizure of 179 packages of the drug is the latest result in an effort to curb maritime trafficking of illicit substances across the Pacific Ocean—an issue also being addressed by the United States through a series of deadly attacks in the Caribbean against vessels suspected of carrying drugs.

Omar García Harfuch, Mexico’s secretary of security, reported in a post on X that the interception of the vessel—known as a “narco-submarine”—took place in Mexican waters near Manzanillo, in the state of Colima. Three people have been arrested over suspected ties to the shipment.

The Mexican navy (Semar) said that the operation involved an ocean patrol vessel, two fixed-wing aircraft, two rotary-wing aircraft, and two interceptor boats. It also received support from US Northern Command and the Joint Interagency Task Force, which provided intelligence to locate the target at sea.

Harfuch emphasized that this action adds to other seizures made during the past week, which have resulted in the confiscation of approximately 10 tons of cocaine. According to the secretary, “this represents a direct and multimillion-dollar blow to the financial structures of organized crime, preventing millions of doses from reaching the streets and protecting the safety of Mexican families.”

Since at least last year, Semar has been monitoring a transnational network that uses the routes known as La Gorgona and El Desierto to transport narcotics and other illicit goods from Ecuador and Colombia. The route includes strategic points such as the Galápagos Islands and Clipperton Island before reaching Mexican shores, including Punta Tejupán in Michoacán. According to an investigation published by N+ Focus, the final destination of these shipments is the US market.

Criminal organizations use speedboats, submarines, and semi-submersibles, often homemade from fiberglass, to evade radar and maritime surveillance systems. Between 2023 and early 2025, monitoring and enforcement operations conducted by Semar resulted in the seizure of more than 111 tons of cocaine, 223 illegal maritime vessels, and the arrest of 476 suspected traffickers of Ecuadorian, Mexican, Colombian, and Central American nationalities.

The US government has pressured Mexico to intensify its fight against drug trafficking. Last year, the trafficking of synthetic drugs like fentanyl was used by the Trump administration as justification for imposing tariffs on Mexican imports.

Since then, Mexican president Claudia Sheinbaum has announced a tougher strategy against the cartels, which includes increased surveillance on maritime routes and borders, as well as the extradition of dozens of those convicted of drug trafficking offenses to the United States.

For his part, US president Donald Trump launched a campaign of direct confrontation against organized crime, even in international waters. According to The New York Times, Trump instructed the Pentagon to use military assets against Latin American cartels designated as terrorist organizations, representing the most aggressive strategy of his administration in this area.

Trump’s decree aimed to establish a legal basis for conducting both maritime and land military operations in foreign territory, marking a significant shift in US security policy by assigning to the military functions traditionally reserved for law enforcement agencies.

This policy led to the first US attack on a vessel that, according to the Trump administration, was transporting drugs from Venezuela to the United States. That incident occurred on September 2 in international waters of the southern Caribbean Sea and left 11 people dead, allegedly linked to the Tren de Aragua gang. Since then, dozens of similar attacks have been recorded in the Caribbean and the Pacific, with an estimated death toll of approximately 145 people.

This is the only S’pore cafe to make the World’s 100 Best Coffee Shops list

Published

on

Apartment Coffee ranks sixth on the list & has been crowned the best coffee shop in Asia

On Monday (Feb 16), the second edition of the World’s 100 Best Coffee Shops ranking was revealed at CoffeeFest Madrid 2026.

And one Singaporean café has made the cut, ranking impressively high.

Apartment Coffee retains its sixth-place spot in the 2026 ranking, the only café from Singapore to feature on the list this year.

It holds the same position it earned in 2025, and has been crowned the best coffee shop in Asia for the second year in a row. So, who’s behind the café, and how did it manage to clinch such a prestigious award not once, but twice in a row?

Apartment Coffee was founded in 2018

Apartment Coffee was first established along Lavender Street eight years ago, by 2018 Singapore Brewers Cup Champion, Yeo Qing He, before it moved to its current premises in Selegie in 2022. It also recently expanded to Serangoon, with the opening of Apartment Roastery in Jun 2025.

The café is well-known for its minimalist, tranquil interior of white walls and natural accents, which offers an escape from the city’s constant buzz. It has a short, curated menu that highlights the craft behind each pour-over coffee cup, from careful bean selection to precise roasting and brewing.

In fact, their beans are carefully selected firsthand during the team’s travels to renowned coffee regions like Colombia, Costa Rica, Rwanda and Kenya.

Yeo said in an interview with The Straits Times that the “focus on experience” differentiates Apartment Coffee from other local coffee shops. “This is also why we don’t do takeaways at our coffee studio,” he added.

Over the years, the café has amassed numerous accolades, including second place in the Singapore Brewers Cup 2022 and first place at the Singapore Roaster Forum 2019. Its sixth-place finish in the 2026 World’s 100 Best Coffee Shops ranking is the latest addition to its growing list of achievements.

Other notable mentions

The World’s 100 Best Coffee Shops List is an annual event that ranks cafés around the globe across nine criteria, including the quality of coffee, the barista expertise, sustainability practices, consistency and innovation.

It has quickly earned a reputation as the coffee world’s equivalent of the Michelin Guide. The event’s credibility stems from a transparent voting system that combines expert opinions (70%) with public opinion (30%), alongside a nomination and final selection process.

Given how well-loved Apartment Coffee is, it wouldn’t be surprising if the café makes the list a third time in the coming year.

Apart from Apartment Coffee, there are other notable mentions, including 14 cafés from Asia that made the 2026 World’s 100 Best Coffee Shops list.

Among the highest-ranking Asian entries are Malaysia’s Story Of Ono in Petaling Jaya, which climbed one spot to eighth this year.

South Korea’s Momos Coffee Flagship Store ranks 22nd, while Japan’s Ult Coffee comes in at 24th. Last year’s honorees also return, including Japan’s Koffee Mameya Kakeru (28th), China’s Espresso Alchemy (31st), and the Philippines’ Yardstick (34th).

Taiwan maintains a strong presence with four newcomers: Coffee Sind (36th), Keep Coffee Roastery (46th), Tomorrow Coffee Roasters (57th), and Coffee Stopover Black (78th).

Other first-time entrants include South Korea’s Ruli Coffee (51st), Thailand’s Fika & Co. Cafe (61st), and Malaysia’s Coffee Stain in Kuala Lumpur (84th).

Microsoft’s new RTO policy starts Feb. 23, bringing Seattle-area workers back 3 days a week

Published

on

Remember that return-to-office mandate Microsoft announced last fall? It’s almost here.

Monday, Feb. 23 — yes, next week! — will mark the start of the company’s new policy requiring Puget Sound (a.k.a. Seattle-area) employees who live within 50 miles of a Microsoft office to show up at least three days a week, the company confirmed in response to GeekWire’s inquiry.

It’s a big shift for one of Big Tech’s last holdouts on flexible work. It’s also a potentially significant development for local traffic, given that there are more than 50,000 Microsoft employees in the Seattle region, at last count.

“Gird your loins and prepare for a potentially longer commute,” the Bellevue Chamber wrote in its newsletter, in an item titled, “Get Your Booty Back to Work: Microsoft’s Turn.”

The good news: Sound Transit’s Crosslake Connection is set to open March 28, finally linking Seattle and the Eastside by light rail across Lake Washington — connecting downtown Seattle to downtown Bellevue and the Redmond Technology station at Microsoft headquarters.

The Seattle-area rollout is the first phase, with other U.S. offices next and international locations later this year. The policy replaces Microsoft’s previous hybrid arrangement, which let most employees work remotely up to half the time without manager approval. 

The company isn’t dictating from above which three days people will need to be in the office. Specifics are left to individual teams and managers. Some groups may require more than three days, and certain customer-facing roles like field sales and consultants are exempt.

The mandate brings Microsoft in line with Google and Facebook parent Meta, which have similar three-day requirements. Amazon, the region’s other tech giant, went further last year, requiring employees to be back in the office five days a week.

In her memo to employees last September, Microsoft EVP and Chief People Officer Amy Coleman said the change isn’t about cutting headcount. “It’s about working together in a way that enables us to meet our customers’ needs,” she wrote.

Still, the mandate could impact the workforce through attrition, consistent with what has happened at other companies that have implemented tighter RTO policies. The new policy comes after Microsoft cut more than 15,000 jobs globally last year.

McCoy Tyner Quartet’s 1991 “New York Reunion” Album Reemerges on 2LP Pink One Step Pressed 180-gram Vinyl: Review

Published

on

A 180-gram “one step” vinyl reissue of a 1991 release from noted audiophile label Chesky Records featuring jazz legends McCoy Tyner, Joe Henderson, Ron Carter and Al Foster is a good reason to celebrate music and life. It is a reminder of why great recordings and great players still matter.

The performances within New York Reunion are lush, relaxed and overall exemplary, capturing iconic seasoned musicians in an intimate studio setting with then state of the art recording technology. On the album cover, it states that the album was “recorded using a specially modified microphone with all tube Manley Reference electronics by David Manley from Vacuum Tube Logic Of America”  It goes on to say that it was “recorded with minimalist techniques and without overdubbing or artificial enhancement to ensure the purest and most natural sound possible.”

mccoy-tyner-new-york-reunion-hype-sticker

Crafted using the increasingly popular “one step” process, which reduces the number of plating stages required to press a record and can improve overall fidelity, this reissue comes with a strong technical pedigree. The opaque pink vinyl pressing is generally quiet, well centered, and free of obvious surface issues.

mccoy-tyner-new-york-reunion-liner-notes

This is a fine sounding all-digital recording of outstanding musicians playing together effortlessly. Perhaps too effortlessly at times. Feel wise, I’m reminded at points of those later period Oscar Peterson CDs on Telarc which at times sounded somehow too pristine and spotless for my tastes (and I say this as a pretty deep Peterson fan). Yet there are no doubt many lovely performances throughout New York Reunion such as Mr. Henderson’s extended solo sax intro (and outro) on Side 3’s “Ask Me Now” before Mr. Tyner comes in for an extended duet essentially.

mccoy-tyner-new-york-reunion-cd

Generally, I’ve enjoyed New York Reunion. My only question (not a complaint) is whether this pressing might have benefitted from some more empathetic mastering for vinyl? Don’t get me wrong, it sounds good: clean, crisp, and natural. I just wish it leaned a touch warmer. That said, considering the explicit commitment to avoiding “artificial enhancement” which would include equalization, this feels like one of those “it is what it is” scenarios.

Based on available online information, this new 2LP limited edition of 2,000 copies appears to mark the first time the complete New York Reunion album—all eight tracks originally issued on a single CD in 1992—has been released on vinyl. Earlier vinyl editions from 1992 and 2016 do exist, but those appear to have been single LP versions rather than the full 2LP presentation.

mccoy-tyner-new-york-reunion-prior-lps

At the time of this review The McCoy Tyner Quartet’s New York Reunion can be found easily on Amazon. I have not seen any indication of whether a standard (and perhaps less pricey) black vinyl edition will be available in the future.

Where to buy: $69.98 at Amazon

A transparent iPhone Air with a working SIM slot looked like a hardware hack for the ages, but it also showed exactly what got sacrificed when factory design margins disappeared.

In a new video, YouTuber Linzin took viewers on a 22-minute journey through Huaqiangbei, China’s famous electronics market. There, technicians worked their magic by laser-stripping the rear glass of an iPhone Air for a see-through effect.
They didn’t stop there and milled space for a SIM slot directly into the frame. They also handled delicate board-level microsoldering to make the eSIM-only iPhone Air work with a physical SIM card.
The modified phone powered on, connected to a carrier, and worked just fine. It did run hotter under load and lost its water resistance.
