Markoff··on F-Droid 2.0
So "Fdroid, Fdroid 3rd party, Forgejo(Codeberg), GitHub, GitLab, IzzyOnDroid, CoolApk, Tencent App Store, vivo App Store (CN)"

VS

"APKMirror, Aptoide, F-Droid, IzzyOnDroid, APKPure, GitLab and GitHub"

so 3 chinese app stores vs APKMirror, APKPure and Aptoide, I think I'd trust more APKM over the rest, personally I update only from Github/Fdroid and APKPure/Aptoide I have disabled

China doesn't run on cards or cash - it runs on app-based payments. WeChat Pay and Alipay rule, and while you could use both as a tourist before, WeChat is launching a new dedicated payment app for tourists. It's called TenPayGo and you can pay with it wherever WeChat Pay is accepted.

You download it, set it up with your email address, and you can choose to use Apple Pay, another payment wallet ("nearly 60" international ones are supported), or your card directly through it. Then, every time you make a purchase in China with the app, you are charged by your mobile wallet or your card.

The app can also be used to identify landmarks or objects by taking a photo of them, and it can translate menus for you too. It will soon support tickets for public transport in Shenzhen, as well as easy tax refunds (again, Shenzhen first).

just so you know you could replace Obtainium and F-Droid with APKUpdater which covers both sources and even more, I am using it alongside Aurora

https://github.com/rumboalla/apkupdater

Markoff··on F-Droid 2.0
You can use APKUpdater instead, it supports APKMirror, Aptoide, F-Droid, IzzyOnDroid, APKPure, GitLab and GitHub, I tried Obtainium and it was PITA to set up, I am much happier with APKUpdater for apps not covered by Aurora Store

https://github.com/rumboalla/apkupdater

Markoff··on F-Droid 2.0
I remember Obtainium being PITA to set up, is there any benefit in ObtainX over APKUpdater from rumboalla? Seems to have way more sources.

Why limit yourself only to F-Droid when in APK Updater you can have APKMirror, Aptoide, F-Droid, IzzyOnDroid, APKPure, GitLab and GitHub?

I don't really need app to discover other apps, I need app to install/update the apps I already know.

anyway I don't get what has official name since 60s to do with how people commonly called it up until recently, at least in 90s it was frequently called positive discrimination, heck I even remember when black people could be called black and not african american

judging by the response I assume "positive discrimination" ain't mainstream anymore in the US

she started at earlier age, parents at that age can easily brainwash a kid, the kid will "enjoy" whatever they will tell him to enjoy, now after years of abuse, sorry, I mean training, she doesn't even most likely know there is any alternative to life like this

I can assure you Chinese parents can very easily force 6yo to do anything 2 hours a day (she spends most likely more hours a day than they claim), what is she gonna do, what's her other alternative at this age?

before opening - I hope she is not Asian

of course she is Asian, poor kid, Asian parents do this to their kids, so they excel in one field/discipline after hundreds of hours training and lost childhood, it's completely meaningless victory for her future life, but at least parent's ego was stroked and they have now bragging rights, sad...

for anyone who thinks about calling me a racist - lived in China for years, my wife is Chinese and I have mixed kids, so I am bit familiar with Chinese/East Asian parenting (and trying to stop ideas like these ocassionally)

I remember when it was called publically "positive discrimination", but I guess it's not part of the newspeak, because everyone can see it's actually a discrimination even if you slap there "positive" to make it look better.

Markoff··on Jehovah's Witnesses allow blood-derived products but keep ban on whole-blood
The Jehovah’s Witnesses have partly eased their longstanding prohibition on the medical use of donated blood, allowing members to receive products derived from blood but maintaining a ban on transfusions of whole blood.

The policy, announced Friday, is the second revision this year in what has long been one of the most controversial and distinctive teachings of the religious organization.

The new policy says that individuals can receive products derived from blood donated by other people. It says they can receive medical treatments that involve the use of the four main components of whole blood: plasma, platelets and red and white blood cells.

“Each Christian must make his own personal decision about the use of these four primary components in all medical and surgical care,” said Geoffrey W. Jackson, a member of the Governing Body of the organization, based in New York State.

The new announcement also allows members to decide as a matter of individual conscience whether to donate blood to be used for blood products for the medical treatment of others.

But the organization continues to oppose members receiving transfusions of whole blood or donating blood for that purpose.

In March, the Governing Body also announced a revised policy, authorizing members to have their blood stored for their own future medical treatment, but not for others’.

Critics have faulted the organization for prohibiting the use of a proven treatment that can be lifesaving in replenishing blood lost in surgeries, accidents or violence. Critics, including former church members, say that the teaching has led to deaths that could have been prevented.

The Jehovah’s Witnesses’ longtime opposition to blood transfusions derives from their interpretation of Bible passages requiring believers to “abstain” from blood. While Jewish and other Christian religious traditions have interpreted this as a dietary law, Jehovah’s Witnesses have extended that prohibition to transfusions.

Blood components are often used for specific treatments.

Plasma, the liquid component of blood, is often used for those suffering from trauma or certain diseases, according to the American Red Cross. Red cells can be used to treat conditions such as anemia and white cells to treat certain infections. Platelets are used in some cancer and other treatments.

Members shouldn’t make the decision on using blood products lightly, Paul Gillies, international spokesperson for the Jehovah’s Witnesses, said in an interview.

“What we’re saying is you have to pray about it, you have to study it, you have to see what the Bible has to say about it, because blood in the Bible represents life,” Gillies said. Members need to consider all these factors before reaching “a decision that you feel happy about with your God.”

Jehovah’s Witnesses, who emerged in 19th century America, share many Christian beliefs with other churches but diverge on key theological issues, such as the nature of Jesus and biblical prophecy. They are almost alone in their beliefs about blood transfusions. Jehovah’s Witnesses reported a U.S. membership of 1.3 million in 2025, with a worldwide membership of 9.2 million in more than 200 countries and territories.

Markoff··on People hooked on vapes try a new way to quit: cigarettes
No need to be drama queen. I am also 40+, had for sure 10-20 cigarettes in my teenage years to try it and on social ocassions with friends, never saw the appeal, found the taste disgusting (and remember being dizzy) and don't remember my 1st cigarette at all. For the record I dislike as well taste of beer or coffee, got used to wine, which I drink only when visiting father or him visiting me, so totally like twice a year (though it's then multiday affair). It's same with alcohol addiction, drank fairly enough during teenage years, then pretty much stopped completely during 20s (only rarely with colleagues), then around 30 while in China was drinking daily for lunch and dinner 40+ % spirit (baijiu) for months with colleagues, then completely stopped overnight after finding better (but less laid-back) job.

Now recreational marijuana (ideally through bong) is way way more appealing than dumb tobacco cigarettes which do nothing, had it during my teenage years and also during my 20s on different ocassions with colleagues/friends (one of them used it during cancer treatment) and I can see myself having some even now in 40s if I could buy it legally.

Markoff··on Chinese paint cuts wall temperature by 25 degrees Celsius in summer test: report
"According to an R&D director from the Suzhou-based venture, on a clear 30-degree (86 Fahrenheit) day, a treated tank’s surface temperature can drop by roughly 25 degrees"

All I see in their claim is ambient temperature 30C, while surface heated in sun easily to 55C (or even more) with this paint claiming 97% reflectance to keep it at ambient temperature or slightly above.

Obviously the paint can't make surface cooler than ambient.

Markoff··on Robin Williams' Daughter to Fans Creating AI Videos: 'Have Some Shame'
I will play devil's advocate:

2. Nobody forces her to be on platforms where she can meet with AI BS of her father, she can interact only with her friends to avoid public BS and not try to be public celebrity (only thanks to beging his daughter, not because she achieved something on herself)

3. She is known ONLY because she is Robin William's daughter, somehow I feel there are monetary reasons behind her complaining, if not, then follow point 2

Markoff··on Chinese paint cuts wall temperature by 25 degrees Celsius in summer test: report
The research team overcame this hurdle by taking biomimetic inspiration from the microscopic structure of human skin wrinkles. By assigning various functional fillers to work collaboratively, they achieved both high reflection and emission within a much thinner layer.

This design reportedly reduces the coating’s thickness from 500 micrometres to 100 micrometres – thinner than a standard sheet of A4 paper – while driving both solar reflectance and infrared emissivity up to 97 per cent.

The coating is also exceptionally durable. During its 180-day on-site trial in Hainan, it endured 40,000 scrub tests without the paint film blistering or peeling. Based on this ageing rate, developers estimate its effective lifespan at up to 15 years.

The project is an example of scientific research bridging the gap to industrial application.

Wang Fuqiang of HIT developed the foundational coating during his academic research. However, after publishing his findings, the project was largely shelved – until Wang crossed paths with the state construction corporation, which had been hunting for exactly this type of advanced cooling solution.

The two parties then joined forces to drive the technology towards commercialisation.

Starting with laboratory samples, they spent several years on testing, optimisation and validation. Ultimately, they forged a manufacturing process capable of stable, large-scale production without compromising the material’s optical performance.

But I wonder whether it is really significantly better than currently used paints...

The super-coating, which can help cool buildings, goes into mass production, making the leap from lab to industry

China has begun mass production of a super-coating that can cut wall temperatures by 25 degrees Celsius in summer, according to the state-run Science and Technology Daily.

The material, which has undergone six months of real-world testing at a petrochemical plant in the southern island province of Hainan, uses the principles of radiative cooling. It requires neither electricity nor cooling agents and its overall performance is reportedly the highest among known global competitors, according to the report published on September 7. The coating may also have potential for broader use in public infrastructure and homes.

The need to reduce the effects of heat on buildings was apparent in Europe this summer when record heatwaves left many residents sweltering in homes without air conditioning.

The coating has already transitioned from a laboratory innovation into mass production.

Following dozens of trial batches, the research team has established manufacturing standards – spanning raw material grinding and formulation, right through to final product testing. The annual production capacity was 600,000 tonnes, the report noted.

At a petrochemical refinery in Hainan, the scorching sun routinely bakes a row of 3,000 cubic metres (106,000 cubic feet) spherical liquefied gas tanks. Without immediate cooling, internal pressures would surge, posing severe safety risks.

Previously, the facility relied on highly water-intensive sprinkler systems to cool the tanks. Now, clad in this super-coating, the tanks achieve a remarkable self-cooling effect with zero energy consumption.

Composed of tailored inorganic fillers and polymer resins, the coating boasts the dual properties of high solar reflectance and strong thermal emittance.

It reflects most solar radiation while emitting the tank’s accumulated heat outwards as infrared energy – without the need for power or refrigerants. The pioneering material was jointly developed by the state-owned China Construction Eco-Development Company, headquartered in Suzhou, and the Harbin Institute of Technology (HIT) in Heilongjiang province.

According to an R&D director from the Suzhou-based venture, on a clear 30-degree (86 Fahrenheit) day, a treated tank’s surface temperature can drop by roughly 25 degrees, reducing internal temperatures by about 7 degrees.

Achieving an equivalent cooling effect via traditional sprinklers would consume an estimated 35 tonnes of water daily per tank, by some estimates.

“Even during extreme heatwaves, the cooling coating can maintain the tank’s interior at a safe temperature,” the report quoted Li Xiang, head of the R&D centre at China Construction Eco-Development, as saying.

This is made possible by a specific infrared emission window. Scientists have long known that within the atmospheric infrared band of 8 to 13 micrometres, heat can penetrate the Earth’s atmosphere and dissipate directly into the freezing vacuum of space.

However, thick applications are required for traditional radiative cooling materials to be both highly reflective and highly emissive. This bulkiness leads to a host of drawbacks, including higher costs and impaired heat dissipation efficiency.

Why should library let ANYONE use the Wi-Fi? I am probabky old school when I think people go to library to rent the books and that should be the main purpose of the library, not provide some free co-working space for cheapskates.

Markoff··on Germany turns on Brussels as Chinese car sales on track to exceed 1M in 2026
they are not necessarily near future if you don't threaten companies and buyers with 2035 ICE cars ban

if we didn't have subsidies and extra taxes on ICE the market would be completely different, EVs still can't compete for anyone not living in own house with FV, even if you would save significant amount of money on each km the price difference would pay itself after hundreds of thousands km, if whole market was not overregulated by EU pushing EVs and trying to discourage people from buying EU produced ICE cars

up until very recently 90% of newly registered EVs in Czechia are registered on company, only 10% of already very small EV market share are ordinary private buyers and mind that's still with benefits like cheaper/free parking for EVs or (up until recently) free highways

Markoff··on Germany turns on Brussels as Chinese car sales on track to exceed 1M in 2026
final desperate move before VW death, they keep shoting themselves into foot with green deal and other EU nonsense and then complain when Chinese come running...

"Five years ago, Chinese-brand vehicles barely registered in Europe selling 66,000 units out of a market of more than 11 million new cars. By 2023 that share had climbed to roughly 3%. Then it kept climbing: 6.1% in 2025, and 9.2% in the first half of 2026 alone, with Chinese manufacturers now regularly outselling established names like Ford, Audi and Mercedes-Benz in individual months.

Chinese brands are on track to sell more than 1 million cars in Europe in 2026 for the first time — a threshold that would have seemed implausible just three years ago, when sales were smaller than what a single mid-size European manufacturer might convert in a good quarter.

Much of that growth has come through a route the existing tariffs don't cover. The EU's elevated duties on Chinese EVs, in place since 2024, briefly slowed the pace that year — but manufacturers pivoted hard into plug-in hybrids, a category exempt from the levies. Chinese brands' share of European PHEV sales jumped from 2.5% to 13.7% in just twelve months."
