fsh··on Satellite reveals immense scale of GPS signal tampering
GNSS receivers are passive devices that receive beacons broadcasted from the satellites. It's technically impossible to spy on someone with GNSS.
fsh··on Swiss parliament lifts ban on new nuclear power plants
With nuclear energy, you are dependent on whoever has uranium. This is not a theoretical risk, and already has political and economic consequences for the few countries with a large nuclear energy share [1]. It would be much worse if a significant amount of global energy was produced with nuclear energy.

fsh··on Swiss voters reject proposal to cap population at ten million
The SVP campaign in favor of the initiative was something else. Half the country is plastered with their posters, and social media is full of astroturfing. It didn't pay off this times, but the propaganda dominance of this party is concerning.
fsh··on Tectonic: A modernized, complete, self-contained TeX/LaTeX engine
I recently had a document break because I used umlauts together with the subfigs package. Apparently both use " characters internally and clash badly. This is not a particularly exotic use case.
fsh··on Wow, if it's this easy in 1998, I bet it'll be even easier in 2026
The original iPhone was genuinely terrible. A 2006 Nokia could surf the web on the go and tell you where you are. The iPhone could do neither, since Apple did not include a 3G modem or GPS. It also did not have any apps, and one of the key features highlighted by Steve Jobs was voicemail. The 3G one year later was the first truly usable iPhone.
fsh··on Wind and solar generated more power than gas globally in April 2026
Coal is much cheaper than gas.
fsh··on AMD pulls a bait-and-switch on Linux users with Vivado licensing changes
No, AMD wants to collect some rent from people running Vivado in CI/CD environments.
fsh··on AMD pulls a bait-and-switch on Linux users with Vivado licensing changes
Vivado is an IDE for programming AMD FPGAs. One cannot use it without buying AMD hardware.
fsh··on White Rabbit – sub-nanosecond synchronization for large distributed systems
The roundtrip time is measured and compensated. Even NTP does this. Knowing the distance is not necessary for time synchronization.
fsh··on Why is Vivado 2026.1 dropping Linux support for free tier?
The users are paying plenty of money for AMD FPGAs.
fsh··on Why is Vivado 2026.1 dropping Linux support for free tier?
This is terrible news for university users trying to professionalize their FPGA development with CI/CD. Which is probably the point of the change.
fsh··on Through the looking glass of benchmark hacking
I don't get the point. The model has presumably been trained on all public GitHub code, so the evaluation is tainted anyway.
fsh··on Quantum Key Distribution (QKD) and Quantum Cryptography (QC)
At that point you can just pre-share a key and use AES.
fsh··on Belgium stops decommissioning nuclear power plants
Chernobyl was supposed to be an economically viable means of generating electricity. Comparing a tiny billion-dollar submarine reactor to a power plant simply doesn't make any sense.
fsh··on An AI agent deleted our production database. The agent's confession is below
I find these posts hilarious. LLMs are ultimately story generators, and "oops, I DROP'ed our production database" is a common and compelling story. No wonder LLM agents occasionally do this.
fsh··on I'm never buying another Kindle
AZW is clearly not PDF based. Try opening an actual PDF on a Kindle and compare the experience.
fsh··on Why Japan has such good railways
Japanese public transport is good, but no match for the Swiss system. Outside of big cities, the coverage is spotty, and even reasonably large towns are only connected by reserved-only trains every couple of hours that get booked out days in advance. The almost complete lack of digitization is also remarkable (reservations have to be made with machines in the stations). There are other annoyances such as the public transport in Tokyo shutting down completely at midnight. In contrast, the Swiss government-owned system delivers usable connectivity to almost any human settlement, even most mountain villages. The ticket prices are also not so different, which is surprising considering the large difference of salaries in the two countries.
fsh··on Team from ETH Zurich make high quality quantum swap gate using a geometric phase
I find the editorialized title misleading. They trapped 17000 atom pairs in an optical lattice and demonstrated a high-fidelity quantum gate between the atoms of each pair in parallel. There is no interaction between the atoms of different pairs and no individual control. The experiment demonstrates a very robust gate scheme, but is a long way from a programmable computer.
fsh··on Who is Satoshi Nakamoto? My quest to unmask Bitcoin's creator
It is his real name, and he also used his real surname in early blog posts.
fsh··on F-35 Got Hit
"Quantum radar" is a toy experiment with zero practical applications. The experiments achieved a "quantum advantage" by using entangled photons which only works in the single-photon regime. Since microwave photons are pretty small, this implies incredibly low transmission powers. With the typical return loss of an airplane (stealth or not) detected by a radar antenna, one would have to average for centuries to detect something (assuming the airplane stays there for said centuries). This assumes perfect entanglement with no other imperfections.
fsh··on Artemis computer running two instances of MS outlook; they can't figure out why
To send email.
fsh··on Data centers are transitioning from AC to DC
Essentially none of this is true. The war of the currents was between Edison and Westinghouse, not Tesla. Tesla's downfall was that he turned into a crackpot who rejected modern science, such as Maxwell's equations, and started defrauding investors. Edison was an outspoken opponent of the death penalty, and the electric chair used AC simply because it is much more deadly.
fsh··on In Edison’s Revenge, Data Centers Are Transitioning From AC to DC
It was Westinghouse who pushed the AC grid against his rival Edison's DC approach. Tesla was a minor figure working for both of them for a bit.
fsh··on Two pilots dead after plane and ground vehicle collide at LaGuardia
Many airports have ADS-B transponders in their ground vehicles. You can see them on flightradar or adsbexchange.
fsh··on Italy, Belgium set to lose gas supply after biggest LNG plant bombed
China has a larger population density than the EU. There is more empty land in Europe.
fsh··on Italy, Belgium set to lose gas supply after biggest LNG plant bombed
In 2024, China produced 8 times more electricity from renewables that from nuclear [1], and the renewable share is growing much more quickly. Nuclear is as dead in China as it is elsewhere in the world.

fsh··on Italy, Belgium set to lose gas supply after biggest LNG plant bombed
The French energy sector is more than 50% fossil [1]. If France decarbonizes over the next decades, it will be due to renewables, not nuclear. While the government and population have been extremely pro-nuclear for a long time, the economics just don't work out. The current plan is to barely build enough reactors to replace old ones going off-line over the next decades.

fsh··on Italy, Belgium set to lose gas supply after biggest LNG plant bombed
The real problem are transport and heating. In most countries, those consume significantly more primary energy than the electricity sector and are still mostly fossil fueled. For example, more than half of the primary energy consumed in France is oil and gas. Heat pumps and electric vehicles or trains can now finally change this, but the transition is very slow.
fsh··on Google details new 24-hour process to sideload unverified Android apps
I don't find it reasonable that Google wants to make me wait 24h to install software on a device I own.

Output (minus a lot of emojis): BIG NEWS: We’re excited to share a game-changing structure for the salt of deoxyribose nucleic acid (D.N.A.)! This model introduces some truly novel features that are going to have a massive impact on the biological space.

We know Pauling and Corey previously proposed a model (shoutout to them for sharing the manuscript early! ), but after a deep dive, we found a few pain points:

1. The X-ray data suggests it’s a salt, not a free acid—without those hydrogen atoms, the structure just doesn't hold up under pressure.

2. Some of those van der Waals distances are a bit too tight for comfort.

Fraser also suggested a three-chain approach, but it was a bit too "vague" for us to provide actionable feedback on.

So, we’re pivoting to something radically different: A double helix! Two helical chains coiled around the same axis. We’re talking: Phosphate di-ester groups Right-handed helices Bases on the inside, phosphates on the outside (optimized for cation access! )

The structure repeats every 10 residues (34 A), keeping everything perfectly aligned. We’re leaning into the standard configuration to ensure maximum stability and biological interest.

The future of genetics is here. Let’s disrupt the fibre axis together! #DNA #Innovation #Biology #Science #DoubleHelix #GameChanger
