Comment I'm an astronomer who studied supernovae ... (Score 4, Interesting) 30

... and can say that the question, "how does the luminosity of type Ia supernovae depend on redshift?" is a very, very complex one. The number of factors which come into play is large (metallicity, age of the binary system, extinction in the local environment, extinction in the intergalactic environment, corrections for photometric calibration as a function of redshift, etc.), and it's easy to fall into the trap of finding one correlation that seems to explain everything.

I'll add that it's particularly easy, in my opinion, for theorists to fall into this trap.

Submission + - Iran's Capital Is Moving. The Reason Is an Ecological Catastrophe (scientificamerican.com)

An anonymous reader writes: Amid a deepening ecological crisis and acute water shortage, Tehran can no longer remain the capital of Iran, the country’s president has said. The situation in Tehran is the result of "a perfect storm of climate change and corruption,” says Michael Rubin, a political analyst at the American Enterprise Institute. “We no longer have a choice,” said Iranian president Masoud Pezeshkian during a speech on Thursday. Instead Iranian officials are considering moving the capital to the country’s southern coast. But experts say the proposal does not change the reality for the nearly 10 million people who live in Tehran and are now suffering the consequences of a decades-long decline in water supply.

Manufacturer Remotely Bricks Smart Vacuum After Its Owner Blocked It From Collecting Data (tomshardware.com) 123

"An engineer got curious about how his iLife A11 smart vacuum worked and monitored the network traffic coming from the device," writes Tom's Hardware.

"That's when he noticed it was constantly sending logs and telemetry data to the manufacturer — something he hadn't consented to." The user, Harishankar, decided to block the telemetry servers' IP addresses on his network, while keeping the firmware and OTA servers open. While his smart gadget worked for a while, it just refused to turn on soon after... He sent it to the service center multiple times, wherein the technicians would turn it on and see nothing wrong with the vacuum. When they returned it to him, it would work for a few days and then fail to boot again... [H]e decided to disassemble the thing to determine what killed it and to see if he could get it working again...

[He discovered] a GD32F103 microcontroller to manage its plethora of sensors, including Lidar, gyroscopes, and encoders. He created PCB connectors and wrote Python scripts to control them with a computer, presumably to test each piece individually and identify what went wrong. From there, he built a Raspberry Pi joystick to manually drive the vacuum, proving that there was nothing wrong with the hardware. From this, he looked at its software and operating system, and that's where he discovered the dark truth: his smart vacuum was a security nightmare and a black hole for his personal data.

First of all, it's Android Debug Bridge, which gives him full root access to the vacuum, wasn't protected by any kind of password or encryption. The manufacturer added a makeshift security protocol by omitting a crucial file, which caused it to disconnect soon after booting, but Harishankar easily bypassed it. He then discovered that it used Google Cartographer to build a live 3D map of his home. This isn't unusual, by far. After all, it's a smart vacuum, and it needs that data to navigate around his home. However, the concerning thing is that it was sending off all this data to the manufacturer's server. It makes sense for the device to send this data to the manufacturer, as its onboard SoC is nowhere near powerful enough to process all that data. However, it seems that iLife did not clear this with its customers.

Furthermore, the engineer made one disturbing discovery — deep in the logs of his non-functioning smart vacuum, he found a command with a timestamp that matched exactly the time the gadget stopped working. This was clearly a kill command, and after he reversed it and rebooted the appliance, it roared back to life.

Comment Re:While I like the sentiment, it's unenforceable (Score 1) 70

While I agree that I don't understand how this is price fixing, I'm not sure your argument is valid. Standard Oil is a pretty well-known example of producers colluding to keep the price up, but they still kept it low enough that people found a ton of ways to make use of oil from transportation to heating to labor productivity. Using the "loss of demand" measurement we would probably have missed it.

I think the issue here isn't collusion per se, but rather that an information disparity exists and disadvantages tenants and is being perceived as "price fixing" because there really isn't any other mechanism currently to deal with the problem.

One alternative solution would be to level the playing field by finding some way to make tenants and landlords alike have access to the same level and quality of information. I would suggest perhaps all rents and rent offers should be published in a way that anyone can apply their own algorithm on either side of the negotiation.

New Large Coral Reef Discovered Off Naples Containing Rare Ancient Corals (independent.co.uk) 13

Off the southwest cost of Italy, a remotely operated submarine made "a significant and rare discovery," reports the Independent — a vast white coral reef that was 80 metres tall (262 feet) and 2 metres wide (6.56 feet) "containing important species and fossil traces." Often dubbed the "rainforests of the sea", coral reefs are of immense scientific interest due to their status as some of the planet's richest marine ecosystems, harbouring millions of species. They play a crucial role in sustaining marine life but are currently under considerable threat...

hese impressive formations are composed of deep-water hard corals, commonly referred to as "white corals" because of their lack of colour, specifically identified as Lophelia pertusa and Madrepora oculata species. The reef also contains black corals, solitary corals, sponges, and other ecologically important species, as well as fossil traces of oysters and ancient corals, the Italian Research Council said. It called them "true geological testimonies of a distant past."

Mission leader Giorgio Castellan said the finding was "exceptional for Italian seas: bioconstructions of this kind, and of such magnitude, had never been observed in the Dohrn Canyon, and are rarely seen elsewhere in our Mediterranean". The discovery will help scientists understand the ecological role of deep coral habitats and their distribution, especially in the context of conservation and restoration efforts, he added.

The undersea research was funded by the EU.

When you are right you are right. Like usual, if you read the Constitution you find out that these "Stand Alone" agencies likely aren't Constitutional! What you say? Well there are just 3 parts of the government defined - you won't find those agencies described or the mechanisms Congress created in the Constitution if you go look. So they have to exist SOMEWHEE within one of the three branches. If the President is the on that gets to nominate the "principal officers" that are the folks that run these agencies - then they should serve at the President's largess. He is allowed to fire any other principal officer - say the US attorneys - at a whim without any reason. Logically the members on these agency boards, etc. fall in the same bucket.
