Another redesign on the cards for iPhone as EU rules call for removable batteries

Just learned to break open our family phones ...

and found that replacing batteries and screens is quite feasible, if you have the weird screwdrivers, a guitar pick, and some patience. I guess that newly acquired skill will become quite useless in the near future.

Concerning the limited lifetime of phones, I guess it's time to figure out how to prolong that lifetime. For most of us, it's not a hardware issue anymore -- the email app, messenger and browser worked just fine on my old phone. But the software obsolescence made me get a new phone this year.

CERN spots Higgs boson decay breaking the rules

"Too many alternatives to the Standard Model"

The fact that there are so many untested (and some times untestable) theories out there indicates that we throw too much money at theoreticians and too little at experimentalists. This results in a lot of pointless theories and then a lot of PhDs ("Quants") messing up our financial system.

Here's how the data we feed AI determines the results

Re: It's useful

Turn that logic around: If the AI can do it, it's not new and most probably useless.

And don't be all impressed that the AI might pass an exam: The exam itself is only useful as indicator that the examinee might have the smarts to do do useful stuff in his future career.

US, NATO military plans leak: Actual war strategy or pro-Kremlin shenanigans?

Simple explanation for low Russian death count on Mediazona

According to the Mediazona website:

"These numbers do not represent the actual death toll since we can only review publicly available reports including social media posts by relatives, reports in local media, and statements by the local authorities.

The real death toll is much higher. Besides, the number of soldiers missing in action or captured is not known."

So they don't count soldiers who were not officially killed in Ukraine. And the Russian Army seems to have a lot of I centives to keep the official numbers low: Financially they are on the hook for widow pensions, etc., if they acknowledge a war death. And I won't have to spell out how hight casualty numbers might affect their PR efforts.

So, pointing to the Mediazona numbers to question other counts is a bit nonsensical. RtFM!

In the battle between Microsoft and Google, LLM is the weapon too deadly to use

The article's arguments against AI ...

are based on the fact that people might figure out how to do bad things with the knowledge provided by it? Well, you could buy physics and engineering books to figure out how to build a bomb ... no AI required. I guess that's how the North Koreans did it.

From my playing around with ChatGPT, it seems that this AI provides an interface to make searchable information more accessible (i.e., summarizes your search results in coherent sentences). It doesn't fundamentally change the available informtion or change the fact that technology can be used for good or bad purposes. Of course, there is the saying that sufficiently advances science always looks like magic. I guess for the uneducated masses, the current AI is the magic engine that will allow you to build a nuclear bomb or perform other sufficiently complicated 'magic' tasks.

OpenAI rolls out ChatGPT plugins, granting iffy language model access to your apps

Next Step ...

...will be Microsoft opting you into sharing all your data within your Windows / MS cloud ecosystem. Win11 already requires enough comupting power that they should be able to train on you data locally before uploading relevant (marketing) information. Suitably anonymized, of course. Except if you reside in the EU, where they'll require proper consent and anonymization, somewhere in the 2030s.

But apart from my cynical view of the MS/ChatGPT cooperation, do you guys think the new AI engines represent a new user interface to information (+(natural language), +(compilation of multiple sources), -(reliability / reproducibility)) or does it acutally 'generate' knowledge? It seem like everybody assumes the second, but I am somewhat sceptical.

UK prepares to go it alone on post-Brexit science plan

...what the EU wants in a completely separate area

Separate area? Such as signing and abiding by a Brexit agreement.

There is no separate area, the EU agreement is a package deal and you can't pick the parts you like and renegotiate the rest. The EU tried to make this clear from the very beginning, but British politicians were a bit preoccupied with internal politicking and never seemed to get the message.

Intel wants another €3.2b from German gov for Magdeburg mega fab

Free money ...

... so you have given us billions to build this thing. It would be a pity if all that money would go to waste! How about you give us a bit more and we'll consider actually building it. It would be a pity if you'd loose an election because you wasted all that taxpayer money!

It was a mistake to start offering money, but then they did it before and it also crashed and burned back then. But those politicians love this type of thing: they get to spend other people's money, they get a bunch of excited press releases and photo-shoots, and it works magic if they suddenly are out of a job and try to find a place within some friendly industry.

Time for the government to remember its core functions: pay your teachers, maintain a reasonable social net to keep your society stable, fund the army.

Why did Microsoft just buy fiber optic cable company Lumenisity?

Re: Latency is everything

Latency is only important for high-frequency trading, i.e., some broker trying to interject himself between a buyer and a seller by buying faster and then selling with a mark-up. There is no benefit of high-frequency trading to the wider economy -- it has a negative effect as it drives up the cost of trading. So this shouldn't be a good long term business to invest in, as the business model will vanish once the regulators get their act together and agree on shutting it down.

But there is a benefit of low latency data transmission for almost all aspects of computing. The only question is whether hollow-core fibers are the tool for the job. Trading signal attenuation versus speed means that the benefits of hollow core fibers come with a significant cost. So it's a matter of finding the right niche where this trade-off is worth the cost.

Time Lords decree an end to leap seconds before risky attempt to reverse time

The definition of temperature, latent energy, etc.

Temperature describes the average energy in matter. To talk about temperature only makes sense when all molecular degrees of freedom are reasonably equilibrated, including kinetic, vibrational, and rotational degrees of freedom. Molecular collisions very rapidly equilibrate these degrees of freedom and the equilibration between rotation and velocity is actually faster than that between vibration and kinetic energy. It therefore makes no sense to separate out rotation or to claim that rotation is a form of latent energy. While the earth is warmer than space (at a cool 2.7 K, or -270.5 C), all that heat will eventually be re-emitted into space, but fortunately the greenhouse gases in our atmosphere (predominantly water vapor, but unfortunately also CO2) retain the heat from solar absorption long enough to keep us at comfortable temperatures.

Latent energy is energy consumed in a phase transition. E.g., a cooling earth might spend a lot of time at -2 C while all the oceans freeze, emitting a lot of latent heat. Latent heat does not play any role in the understanding of global warming.

In my field of research, we use supersonic molecular beams, expanding a molecular gas into vacuum. Within mm distances from the molecular beam nozzle (microseconds of flight into vacuum), molecules cool from room temperature to few Kelvin. So rotation is not special and equilibrates almost completely within microseconds (faster near room temperature!).

I'll be happy to recommend some textbooks if you want to learn more. I know this stuff pretty well, considering that I develop and perform molecular spectroscopy experiments for a living and teach all aspects of physical chemistry.

Climate pseudo-science versus science

As a scientist, let me inform you that rising atmospheric CO2 does lead to increased temperatures on the earth surface. It's as simple as filling a bottle with a transparent liquid and another with a dark liquid, placing both into the sunlight and observing how one warms up with respect to the other. Only we fill the earth atmosphere with a 'darker', more absorbing gas.

If you want a deeper understanding of the earth thermal equilibrium, you'll have to look up the blackbody radiation spectrum for sun and earth and account for the place where sunlight is absorbed (mostly on the earth surface) and how heat is re-emitted into space (as IR/THz radiation through the atmosphere, with CO2 absorbing some of that, trapping the heat). This has been understood for some 100 years. We now have very good observations that CO2 concentrations and climate were coupled in past millenia and we have good observations showing the correlation of man-made CO2 and climate. The controversy is no more among scientists (crackpots excepted), but among the uneducated and populists.

Re: Didn't someone previously propose 'stretchy' seconds

Great, there goes our standardized system of units. Where is Napoleon when you need him?

TAI = UTC + 37 seconds, am I missing something?

The whole idea of this change to UTC is to remove leap seconds and the announcements stated that this will remove any requirement to play with time until the end of this century. So we'll leave it to the next generations to decide if they want to fiddle with the clocks or accept a few second's shift in time versus the day/night cycle. Stop worrying and trust your grandchildren to make a competent and informed decision about UTC versus UTC1, it's not your business anymore.

Intel reveals pay-to-play Xeon features with software-defined silicon

Stupid Management?

So the company incurs the full cost of developing and producing powerful hardware and software and then sells an inferior product instead. Doesn't sound like a great business decision to me. I'd rather buy from the competition who sells a fully functional product.

To sell a deliberately inferior product sounds like a bad idea to me. It might work if you are the only supplier in town, but it is not a way to build and gain market share in a competitive environment. I believe these managers should go sell razor blades, printer ink, or coffee pods instead.

Germany says nein to Qatari World Cup spyware, err, apps

I wonder if there were any brown envelopes [...] involved

You wonder, really?

The German press talked extensively about the gifts that the various German soccer executives tried to smuggle back home from Katar. E.g., luxury watches in the case of former German Soccer Association president Theo Zwanziger or European Club Association chairman Karl-Heinz Rummenigge. The smarter members of the German delegation were not caught with $100'000 luxury watches, interpret that as you want. I'd expect that less flashy gifts have been transferred more discretely.

Imagine how blatant it must have been if even the Germans were caught with their bribes.

Australian exchange pauses project to move stocks to blockchain

The problem of Blockchain in finance...

The argument for blockchain technologies in finance (including exchanges, cryptocurrency, and the bunch) is that it pretends to solve the problem of trust -- but this problem cannot really be solved.

Do you trust your bank, the stock exchange, your central bank to keep your money safe from fraud, theft, and inflation? They have a good track record, that's why they exist in their current form. If you replace these institutions with blockchain software, then you have to trust the programmers and bookkeepers of the newly created systems. Any blockchain needs to be maintained and stored and your 'safe' transactions still need to be properly recorded. So, really, you now just trust another set of people (unless you are inside the system, be it a bank or a crypto outfit, and roll your own). Be careful whom you entrust with your money <cough>FTX</cough>.

Google wins lawsuit against alleged Russian botnet herders

"DIPLOMACY, n. The patriotic art of lying for one's country."

The short-term gains from lying are usually paid back with interest, as the world catches on to said lies. Same is true for every human interaction in this world: being trustworthy is better for business than being a lying scumbag and cheater.

Case in point is the current cost of Russian foreign policy. They thought that lying about their strategies and goals in Ukraine might pay off internationally and internally. Now they need to enforce a draft and Orwellian speech policies to keep up their extension of diplomacy with other means.

Bumble open sources AI code to automatically blur NSFW photos

Alternative ways to "make the internet a safer and kinder place"...

is to get everybody (including kids) used to the naked human body.

Seriously, I never quite understood the stigma associated with human nakedness. In the West, showing too much leg is considered risqué, whereas in Asia you have to cover up your shoulders. And if we cast the net a bit wider, we can find that showing female hair or eyes is way to revealing, or that exposed breasts and even full nakedness is quite normal.

Back in the days of my PhD, it took the US students exactly two trips to the sunbathing beach (Zürihorn) to realize that the female form is quite ordinary. (Don't look it up, nobody is excited to encounter your misplaced curiosity.) Made me realize how prudish our US cousins are; the locals had stopped staring a long time ago.

The rules about decency are quite arbitrary. Let's change the rules.

The circle of life ... as related to business

Innovation in context of the circle of life is called evolution and should teach us a little something about the futility of grand corporate visions or great weed fields that may or may not sprout the next big thing.

Biological evolution is fundamentally random but is progressing through constant evolutionary pressure and is constantly adapting to new environmental conditions. The right mutation meets the right conditions and you have a great success story. Capitalist business works very much the same way (unless you include rent-seeking and cronyism into the equation), but we tend to re-interpret every success story - with hindsight - as great visionary success from brilliant people.

Let's just face it, Elon Musk, Larry Page, Steve Jobs, and Bill Gates (just to name a few) are not singularly smart engineers, managers, or investors but were the right people in the right place at the right time. An Albert Einstein, surely, they are not. The best a company can hope for is that its smart and creative employees find the right product that meets its moment in the marketplace. These employees will need enough time and space to succeed. The worst those companies can do is to micromanage every aspect of their company and grind all creativity into finely-powdered productivity that can be sifted and quantified in this year's report card.

Elon Musk shows what being Chief Twit is all about across weird weekend

Just for context, Elon Musk tweeted:

“there is a tiny possibility there might be more to this story” behind the attack on Paul Pelosi in San Francisco, linking to an opinion article in the Santa Monica Observer, a site described by fact-checkers as a low-credibility source favoring the extreme right. The article claimed without evidence that Pelosi was drunk at the time of the assault and “in a dispute with a male prostitute.” (cited from the Washington Post; the NYT article reported the same facts.)

Looks like Elon turned off the bullshit filter in his own mind as a warm-up for his actions at twitter.

energy storage ... pulling a train of concrete blocks ...

sounds like a great energy storage solution until you realize that hydroelectric pumping stores much more power with much less infrastructure. Just picture the infrastructure of track, loading dock, and trains and compare that to the small water tube and pump/turbine building that will transport the same mass flow. Also imagine throwing all those concrete blocks into your water storage lake -- their weight and volume will hardly make a difference on the scale of a decent lake.

Bitcoin energy consumption a feature, not a bug, says crypto-miner

Calling others liars is a bit over the top. Doing so without any meaningful arguments is just despicable.

"our problem isn't energy scarcity...because [energy] isn't scarce"

There is a reason why chemists distinguish energy from free energy: Just because energy exists doesn't mean that it can be usefully employed.

So while your statement that "energy isn't scarce" is true, it is also totally meaningless. Usable, clean energy is very scarce. So scarce, that we continue to burn fossil fuels for the majority of our energy needs. So scarce, that we cut down forests for wood pellets. So scarce, that the gasoline price may decide the election outcome in our largest democracies.

The scarcity of clean energy may come to define this century. Already, we saw energy-intense and dirty industry migrate to poorer and less-democratic places -- fundamentally reshaping the development of our world. These forces won't diminish and will define the conflicts of this century. Oil and gas in the black sea may well have tipped the scales for the Ukraine war.

Brain-inspired chips promise ultra-efficient AI, so why aren’t they everywhere?

But what is it good for?

After reading the article, I was left wondering: But what is it good for?

In my mind, the efforts to simulate the brain in silico is based on old-fashioned transistors clicking away while simulating neurons. But apparently, the idea of neuromorphic chips is to leave those transistors unpowered until a stimulus comes along (see: Nature article on the topic), hence the immense power savings. Clearly, this is only useful when you assume that your computer is going to sit idle most of the time and that you fail to power down while idling. The other touted advantage is highly parallel computing.

The big question then becomes: is it helpful to try to model a brain in order to gain advantages from parallel computing and power-down upon idle, or might one just optimize parallel computing and dynamic power use? The former is clearly advantageous when trying to obtain research funding (addressing fundamental questions), while the latter sounds more promising if you want to develop and sell actual silicon. So my prediction would be that brain-inspired chips will remain an active research area for the foreseeable future, without ever moving beyond the stage of a investors' fad. But I am sure that every neuromorphic brain in this world would like to contradict me on that.

Pull jet fuel from thin air? We can do that, say scientists

What an achievement ... in hyperbole

The researchers manage to be quite honest in describing their achievement, but at the same time they do an amazing job hyping their research.

Did you catch that they use an area of about 50 nanoWales (2 Tennis courts, or ~1080 square meter) to make a few drops of jet fuel per hour? And they never mention how much energy went into the pumps, valves and motors required to run the whole set-up, so it is not clear that the set-up creates more energy than it consumes.

This is the current reality of our energy transition -- a lot of hyped achievements that are only realistic when you pay no attention to the man behind the curtain (who is burning that cheap hydrocarbon energy to fuel you pipe dreams).

AI-friendly patent law needed 'as a matter of national security', ex-USPTO boss says

It'll be a big clusterfuck

Your statements nicely illustrate the problem with 'AI patents': So your novel, patentable method would be to use Tensorflow to recognize cat pictures? (Feel free to substitute the cats with whatever you consider useful.) Or do you really, in your heart, want to patent the idea of using AI for recognizing said cat pictures? Or do you want to only patent the use of your particular training data in combination with Tensorflow? Or maybe the use of any equivalent AI system that could give somewhat similar input-to-output results?

Whatever you try to do, either you get a monopoly for an idea as opposed to a method -- and that would break the very innovation the patent system is supposed to foster -- or you try to patent data or software.

AI is so interesting to so many, because it's a black box that promises to solve all problems of this world. Because it's a black box, it's really hard to prove that it cannot, potentially, solve a particular problem. You could spend decades of your life trying to understand and solve a hard problem. Or you could just use this magic box.

I predict that AI will go out of fashion, gradually, over the next 10 years. All those great AI projects will be extremely successful. (You wouldn't tell your boss otherwise, would you? After all, it's research and it's OK to move the goalposts a bit, innit.) But after a few rounds of funding, the weeding-out will begin.

Toyota's truck brand Hino admits faking and fudging emissions data for 20 years

Just follow your nose...

Walking through the city, it's quite easy to spot the cheating diesels: you can easily smell the emitted soot (smells like the dirty old heavy trucks) and the NOx (a sharp smell, somewhat similar to chlorine) all over the place. If you ride a bike, you can get a really nice dose when following an older SUV. And they smell in summer and in winter, so the 'engine protection' clearly is designed to kick in at a wide range of temperatures (although it's worse in winter). I'd therefore be willing to bet that the list in the article (Volkswagen, Nissan, Subaru, Mazda, and Suzuki) is way too short.

I am not sure if the newer ones just have improved diesel engines or if they switched to ordinary gasoline -- most newer SUVs smell a lot less. It's not about which company cheated (all the diesel manufacturers did), but just about who managed to make a transition before getting caught.

No more fossil fuel or nukes? In the future we will generate power with magic dust

So how many microW algae cells would we need to replace a good-sized 1 GW nuclear power plant?

Intel to get $7.3b for Germany fab site as TSMC dismisses Europe plans

Smash n grab

Brings up memories of the last big subsidy grab-and-run operation of Intel and partners in Germany. Back then, a foundry was a paltry billion and a consortium decided to take the billion (why not) and see where the money leads them. Didn't lead anywhere, but it's only taxpayer's money.

I am quite suspicious about attracting investments with large subsidies. You distort the risk/reward calculation with too much money, you'll end up with very risky investments (i.e., investments that probably will not work out). That's Capitalism 1-01. But then, there will be a lot of great photo-ops for the brave politicians before that investment bites the dust. That's the beauty of building billion-dollar infrastructure: it takes so long that only historians can remember the responsible parties by the time it bites the dust.

Algorithm can predict pancreatic cancer from CT scans well before diagnosis

I agree; there is a serious risk of p-hacking if you refine your training versus a small control data-set.

So it sounds like a very promising first step and all we have to do is wait another 5 years until the new data has arrived :).
