US school runs lights 24/7/365: The smart lights have been broken since 2021 | Ars Technica

Even if you aren't in charge of the lighting design of a giant building, there's a valuable lesson here for anyone getting involved with smart home/building technology: make technology an addition to your setup, not a dependency. You still need to install physical light switches in every room, but as a bonus, you can pick light switches that are also controllable via some kind of network. All sorts of smart light switches meet this requirement—normal paddles or even toggles that can also be controlled via Zigbee, Z-Wave, Bluetooth, Wi-Fi, probably Ethernet, or whatever you want. This way, if the Internet is down, or some server explodes, or some cloud company shuts down, the lights will still work.

What you definitely shouldn't do is hard-wire the electricity to be always on and then hope the network to the light fixtures or light bulbs will be around to power them off. That's apparently what happened at this school, and now taxpayers are paying the price.

NASA Is Replacing Its Aging DC-8 With A Boeing 777

The National Aeronautics and Space Administration (NASA) is preparing to say goodbye to its old but iconic Douglas DC-8. NASA has operated the Douglas quadjet for decades, first taking it in February 1986, and using it ever since as a flying science laboratory.

The airplane was not new when it arrived with NASA, having originally been delivered to Alitalia in 1969 and flying with Braniff from 1979 until 1986. For NASA, it flies under registration N817NA, and is used to collect data for a range of experiments on behalf of the world’s scientific community, with operations costing scientists approximately $6,500 per hour.

The DC-8-72 is now approaching 54 years old, and despite being meticulously maintained by NASA, she is reaching the end of her useful life. As such, the Administration has lined up a replacement for the jet - a Boeing 777. //

The DC-8 is fast becoming a rare breed in terms of aircraft still flying. Just three airplanes are listed as being in active service today, the other two with Trans Air Cargo Service, according to ch-aviation. A further two are in maintenance just now, suggesting they could soon fly again. One operates for humanitarian purposes with Samaritan’s Purse, while the other is taken care of by SkyBus Cargo Charters.

Gonorrhea is becoming unstoppable; highly resistant cases found in US | Ars Technica

It has resistance or reduced susceptibility to all drugs recommended for treatment. //

The most highly drug-resistant cases of gonorrhea detected in the US to date appeared in two unrelated people in Massachusetts, state health officials announced Thursday.

The cases mark the first time that US isolates of the gonorrhea-causing bacterium, Neisseria gonorrhoeae, have shown complete resistance or reduced susceptibility to all drugs that are recommended for treatment.

Fortunately, both cases were successfully cured with potent injections of the antibiotic ceftriaxone, despite the bacterial isolates demonstrating reduced susceptibility to the drug. Ceftriaxone is currently the frontline recommended treatment for the sexually transmitted infection.

But health officials said the cases are a warning. "N. gonorrhoeae is becoming less responsive to a limited arsenal of antibiotics," they said.

The Nuclear Fallacy: Why Small Modular Reactors Can't Compete With Renewable Energy - CleanTechnica

Will the small modular nuclear reactor community be able to find an optimized point on the physics vs modularity curve? I don’t think so, and discussed it with Bent Flyvbjerg, global megaproject expert.

He claims Germany has the most stable and cheapest electric grid in Europe, but that is contrary to all the info i have seen.

A Look At NASA's Douglas DC-8 Airborne Science Laboratory

There aren’t many DC-8s left flying in the world today, but there’s one special airplane that is set to have an extended life in a very interesting role. NASA took on a Douglas DC-8 in February 1986 and has been operating it ever since as a flying science laboratory. Here’s what you need to know.

Rocket Report: SpaceX reaches ‘ludicrous’ cadence; ABL explains RS1 failure | Ars Technica
thumbnail

for me the news of the week is that SpaceX not only launched a Falcon Heavy rocket, but two other Falcon 9 missions on separate coasts as well in just five days. The operational challenges of this are immense and, I think, underappreciated outside of people directly involved in this kind of work. //

SpaceX approaches ludicrous cadence. In the movie Space Balls, "ludicrous speed" is the velocity attained by a spaceship traveling much faster than the speed of light. That is the velocity of cadence SpaceX is now approaching with its Falcon family of rockets. On Thursday morning, the company launched a Falcon 9 rocket carrying 51 Starlink satellites from Vandenberg Space Force Base in California. This was the company's fifth launch of 2023.

If you're keeping track at home ... As of January 19, SpaceX has launched a rocket every 3.8 days during this calendar year. Extrapolated out to a full year, SpaceX is on pace for 96 Falcon launches in 2023. While that probably won't happen, it indicates that SpaceX founder Elon Musk's prediction of 100 orbital launches this year was not all that, ahem, ludicrous.

NRC Certifies First U.S. Small Modular Reactor Design | Department of Energy

The U.S. Nuclear Regulatory Commission (NRC) issued its final rule in the Federal Register to certify NuScale Power’s small modular reactor.

The company’s power module becomes the first SMR design certified by the NRC and just the seventh reactor design cleared for use in the United States.

The rule takes effects February 21, 2023 and equips the nation with a new clean power source to help drive down emissions across the country.
