Why would any responsible parent put their child in such danger.

KnuthIsGod··on US–Indian space mission maps extreme subsidence in Mexico City
"Objective:

NISAR is the first of its kind mission, jointly developed by ISRO and NASA. It is an L and S-band, global, microwave imaging mission, with capability to acquire fully polarimetric and interferometric data.

The unique dual-band Synthetic Aperture Radar of NISAR employs advanced, novel SweepSAR technique, which provides high resolution and large swath imagery. NISAR will image the global land and ice-covered surfaces, including islands, sea-ice and selected oceans every 12 days.

NISAR mission’s primary objectives are to study land & ice deformation, land ecosystems, and oceanic regions in areas of common interest to the US and Indian science communities.

NISAR mission will help to measure the woody biomass and its changes track changes in the extent of active crops understand the changes in wetlands’ extent map Greenland’s & Antarctica’s ice sheets, dynamics of sea ice and mountain glaciers characterize land surface deformation related to seismicity, volcanism, landslides, and subsidence & uplift associated with changes in subsurface aquifers, hydrocarbon reservoirs, etc.

Spacecraft Configuration

The Spacecraft is built around ISRO’s I-3K Structure. It carries two major Payloads viz., L & S- Band Synthetic Aperture Radar (SAR).

The S-band Radar system, data handling & high- speed downlink system, the spacecraft and the launch system are developed by ISRO. The L-band Radar system, high speed downlink system, the Solid-State Recorder, GPS receiver, the 9m Boom hoisting the 12m reflector are delivered by NASA.

Further, ISRO takes care of the satellite commanding and operations, NASA will provide the orbit maneuver plan and RADAR operations plan.

NISAR mission will be aided with ground station support of both ISRO and NASA for downloading of the acquired images, which after the necessary processing will be disseminated to the user community

The data acquired through S-band and L-band SAR from a single platform will help the scientists to understand the changes happening to Planet Earth."

KnuthIsGod··on New US phone network for Christians to block porn and gender-related content
"‘You’re a traitor!’ yelled the boy. ‘You’re a thought criminal! You’re a Eurasian spy! I’ll shoot you, I’ll vaporize you, I’ll send you to the salt mines!’

Suddenly they were both leaping around him, shouting ‘Traitor!’ and ‘Thought-criminal!’, the little girl imitating her brother in every movement.

It was somehow slightly frightening, like the gamboling of tiger cubs which will soon grow up into man-eaters."

KnuthIsGod··on An open-source stethoscope that costs between $2.5 and $5 to produce
Amazon in India will sell you a pretty reasonable stethoscope for for $3.

Assuming the usual Amazon, distributor and retailer markups, these probably cost around 50 cents to make in China.

Many poor countries are perfectly capable of manufacturing their own medical equipment

Background: I have worked in hospitals in Bihar & Vellore Tamilnadu, and have university mates, friends and family who worked in hospitals in Mizoram, PNG, Libya, Nepal, Uganda and even South Sudan.

Even the doctors who worked in South Sudan had no difficulty sourcing basic equipment. They did however, have enormous trouble sourcing funding and trained personnel who were willing to work in a potentially lethal situation.

KnuthIsGod··on TurboQuant: A first-principles walkthrough
https://arxiv.org/abs/2604.18555

"This note clarifies the relationship between the recent TurboQuant work and the earlier DRIVE (NeurIPS 2021) and EDEN (ICML 2022) schemes. DRIVE is a 1-bit quantizer that EDEN extended to any bits per coordinate; we refer to them collectively as EDEN. First, TurboQuant is a special case of EDEN obtained by fixing EDEN's scalar scale parameter to . EDEN supports both biased and unbiased quantization, each optimized by a different (chosen via methods described in the EDEN works). The fixed choice used by TurboQuant is generally suboptimal, although the optimal for biased EDEN converges to as the dimension grows; accordingly TurboQuant approaches EDEN's behavior for large . Second, TurboQuant combines a biased -bit EDEN step with an unbiased 1-bit QJL quantization of the residual. It is suboptimal in three ways: (1) its -bit step uses the suboptimal ; (2) its 1-bit unbiased residual quantization has worse MSE than (unbiased) 1-bit EDEN; (3) chaining a biased -bit step with a 1-bit unbiased residual step is inferior to unbiasedly quantizing the input directly with -bit EDEN. Third, some of the analysis in the TurboQuant work mirrors that of the EDEN works: both exploit the connection between random rotations and the shifted Beta distribution, use the Lloyd-Max algorithm, and note that Randomized Hadamard Transforms can replace uniform random rotations. Experiments support these claims: biased EDEN (with optimized ) is more accurate than TurboQuant, and unbiased EDEN is markedly more accurate than TurboQuant, often by more than a bit (e.g., 2-bit EDEN beats 3-bit TurboQuant). We also repeat all accuracy experiments from the TurboQuant paper, showing that EDEN outperforms it in every setup we have tried."

A 5 year old free range kid on a scooter died outside a nearby school a few months ago.

Hit by a SUV

Was riding back from primary school on a scooter, without the mother.

A massive investigation, police, social services, traffic consultants, a million plus spent on upgrading safety, mother and father demonised in the community,etc ...

Teachers involved who responded or gave CPR ( I know some of them) given counselling.

The mother is likely to have lost custody of her other children.

Classic economist fail.

Fail to consider the transaction cost of paying the 13 cents for the Lindt, compared to the free Hersheys.

Plus Lindt sucks.

People give it me all the time as gifts. I give then give it away to random people like couriers.

Godiva on the other hand...

KnuthIsGod··on Microsoft Set for Worst Quarter Since 2008
Microsoft consistently set the bar for mediocrity.

The office workers who use their products do so grudgingly, since Office and Excel are so baked into business ecosystems.

Nobody will shed a tear when the aging dinosaur finally dies.

Unfortunately it has been given a transfusion and a new name, Microsoft 365 Copilot or some rubbish.

KnuthIsGod··on Anthropic, The Pentagon, and the Future of Autonomous Weapons
https://podcasts.apple.com/us/podcast/anthropic-the-pentagon...

"Of course, this story immediately become more relevant with the start of the war, and the reporting that Anthropic's technology was in fact utilized at the start of hostilities.

But what does that mean? How are these models used? And what would a fully autonomous weapons system actually entail?

On this episode, we speak with Paul Scharre, the executive vice president and director of studies at the Center for a New American Security. He has written two books on the subject of AI in warfare, and previously worked inside the Department of Defense on some of these very questions. We discuss the future of autonomous weaponry, and the various ethical and technological dimensions such weapons would entail."
