States demand fiber
Starlink wants billions in grants, but state governments aren’t cooperating

Despite Trump's backing, states aren't giving Starlink the money it demanded.
Jon Brodkin – Aug 21, 2025

"Secretary of Commerce Howard Lutnick told states to 'take a tech-neutral approach' when evaluating Internet providers and to 'provide Internet access for the lowest cost.' The National Telecommunications and Information Administration (NTIA), which is part of the Commerce Department, revised the program rules in a way that made it harder for states to justify spending on fiber networks, despite fiber's clear advantage over satellite in speed and capacity."

SpaceX says states should dump #fiber plans, give all grant money to #Starlink

SpaceX seeks more cash, calls fiber "wasteful and unnecessary taxpayer spending."

Jon Brodkin – Aug 19, 2025

"While subsidizing fiber deployment is more expensive, fiber offers faster speeds and doesn't have the capacity problems inherent in satellite networks."

#SpaceX Pushes States To Scrap #Fiber Plans And Redirect All #Broadband Grants To Starlink

By The Droid Guy
August 19, 2025

"The fight over America’s broadband future is heating up again, and this time SpaceX is taking direct aim at state governments. In a filing with #Louisiana’s Office of Broadband Development and Connectivity, the company argued that the state’s decision to dedicate more than 90 percent of its federal broadband grants to fiber is 'wasteful and unnecessary taxpayer spending.' Instead, SpaceX insists, the money should go to its Starlink satellite network.

SpaceX vs. Fiber: Two Competing Visions

"At the heart of the dispute lies the $42 billion Broadband Equity, Access, and Deployment (#BEAD) program, a federal initiative meant to expand high-speed internet access. Under the Trump administration, rules were rewritten to favor a 'tech-neutral' approach, allowing satellite providers like SpaceX to compete more directly with traditional wired services. Louisiana’s final proposal, however, still leans heavily on fiber infrastructure.

"Louisiana intends to spend about $499 million to connect roughly 128,000 homes and businesses, the majority through a consortium of fiber providers. Starlink, in contrast, was awarded just $7.75 million to serve 10,327 locations. SpaceX argues it could have covered nearly all households for under $100 million, claiming the state ignored the new federal rules that emphasize cost efficiency.

The Case For Fiber

"State officials remain cautious about going all-in on satellites. Fiber, though more expensive to deploy, is widely considered 'future-proof' because capacity can scale dramatically as technology improves. A single fiber line can eventually deliver multi-gigabit speeds without replacing the underlying infrastructure. It’s also immune to congestion issues that plague wireless systems.

"Louisiana’s broadband office has noted concerns about Starlink’s long-term viability, pointing out challenges such as limited spectrum, susceptibility to weather, interference from trees, and capacity strain in densely populated areas. Simply put, fiber can handle the demand of tomorrow, while satellites may hit performance ceilings."

@DoomsdaysCW Une étude révèle que la #LightPollution encourage les #oiseaux à chanter plus longtemps

22 août 2025

"Les oiseaux du monde entier chantent près d'une heure de plus chaque jour en raison de la pollution lumineuse, selon une nouvelle étude.

"La recherche, qui sera publiée dans la revue Science, a utilisé des millions d'enregistrements de #chants d'oiseaux, y compris de #NorthIsland en #Nouvelle-Zélande.

"Natalie Forsdick, présidente de Birds New Zealand, a déclaré à RNZ que plus de lumière signifiait plus de temps pour chanter, construire des nids et se nourrir.

"Mais elle a ajouté que ces activités consommaient de l'énergie et que cela pouvait nuire à leur santé générale.

"C'est comme pour les humains : si vous vous couchez un peu trop tard, vous vous réveillez le lendemain en vous sentant un peu moins bien. J'imagine que les oiseaux peuvent ressentir la même chose, et nous constatons que cela perturbe leurs cycles naturels.

"Elle ajoute que des études antérieures menées en Nouvelle-Zélande ont montré toute une série de résultats, allant de l'absence d'effet à l'augmentation de la prédation nocturne par les goélands marins sur des espèces menacées telles que les goujons bagués.

"Mais l'une des plus grandes préoccupations concernant la pollution lumineuse en Nouvelle-Zélande est son effet sur les oiseaux de mer.

"Chez les jeunes, la pollution lumineuse urbaine peut être confondue avec le clair de lune, attirant et désorientant des espèces comme le pétrel de Cook ou le puffin de Hutton.

"Les oiseaux risquent alors de se poser en catastrophe ou de heurter des bâtiments, et de se blesser ou de s'échouer dans les villes.

"Elle a ajouté que les gens pouvaient aider en éteignant les lumières extérieures lorsqu'elles n'étaient pas nécessaires et en demandant à leurs conseils locaux d'envisager un éclairage plus directionnel ou plus faible dans les lieux publics. [Je recommanderais également un éclairage plus chaud : trop de bleu, ce n'est pas naturel].

"Le professeur associé Kristal Cain, de l'école des sciences biologiques de l'université d'Auckland, a déclaré que des recherches supplémentaires étaient nécessaires pour déterminer comment la pollution lumineuse affectait la survie et la reproduction.

"Cet article utilise des données sur les chants d'oiseaux collectées par des milliers de volontaires dans le monde entier, et mesure le moment où les oiseaux commencent à chanter le matin et celui où ils s'arrêtent pour la nuit.

"L'étude a révélé que dans les zones plus lumineuses, les oiseaux commençaient à chanter tôt et continuaient plus tard dans la nuit que dans les zones sombres.

"La plupart des chants d'oiseaux ont été recueillis en Amérique du Nord et en Europe, a déclaré M. Cain. Nous devons encore mener des travaux similaires dans le reste du monde pour voir à quel point ces schémas sont répandus. Les manu d'#Aotearoa sont tout à fait uniques à bien des égards."

"Il est important de noter que toute cette #LumièreArtificielle n'est pas bonne pour nous non plus.

"Les gens pourraient par exemple fermer les rideaux et planter des arbres dans les zones urbaines pour contenir une partie de la lumière."

RNZ · Concern as light pollution encourages birds to sing for longer, study findsVon RNZ News

So, part of my ideal* bedtime routine involves turning off the computer, maybe watching a little Iron Chef or ASMR videos, then turning off the TV, making the rounds, check on kitty, change into comfy PJ's, rearrange the plush pals, and then read for a bit. On nights when my eyes are too tired to read, I'll listen to NPR on my clock radio (which has a timer).

* And yeah, I don't always stick to that routine, and when I don't, my sleep suffers.

Speaking of #LightPollution...

#ScreenTime Before #Bed Is Ruining Your Child’s #Sleep (Here’s What Parents Need to Know)

by Don on February 26, 2025

"Establishing a Screen-Free Bedtime Routine

"Creating a peaceful bedtime routine doesn’t have to be complicated. Start by setting a consistent bedtime and work backward about 30-45 minutes to begin your routine. Replace screen activities with calming alternatives that help signal to your child’s body that it’s time to wind down.

"Begin by dimming the lights throughout the house to support natural #melatonin production. Choose quiet activities like reading stories together, listening to #GentleMusic, or practicing simple #BreathingExercises. Many families find success with a warm #bath or shower, followed by putting on comfortable pajamas and brushing teeth.

"Consider incorporating #mindful activities like #GentleStretching, #coloring, or #QuietPlay with #NonElectronicToys. Some children benefit from a brief #CuddleTime or sharing their favorite moments from the day. Keep a consistent order of activities to help your child feel secure and know what to expect.

"Remember that transition times can be challenging. Give clear, gentle reminders about upcoming routine steps, and offer praise when your child follows along. If your child seems resistant, try making it fun by turning routine tasks into simple games or using visual schedules for younger children.

"Store all devices in another room to avoid temptation, and make the bedroom a #ScreenFreeZone. This helps create a sleep-friendly environment and reinforces healthy boundaries around technology use."

Concern as #LightPollution encourages #birds to sing for longer, study finds

22 August 2025

"Birds around the world are singing for nearly an hour longer each day due to light pollution, a new study has shown.

"The research, to be published in the journal Science, used millions of recordings of #birdsong, including from #NewZealand's #NorthIsland.

"President of Birds New Zealand Dr Natalie Forsdick told RNZ more light meant more time for singing, building nests and feeding.

"But she said those things consumed energy and it could be reducing their overall health.

" 'It's just like with humans, if you go to bed a little bit too late, you wake up the next day feeling a little bit the worse for wear. I imagine that birds could feel that same way too, and we certainly see that it disrupts their natural cycles.'

"She said previous studies in New Zealand had shown a range of outcomes, from no effect to increased night-time predation by black-backed gulls on threatened species like banded dotterels.

"But one of the biggest concerns about light pollution in New Zealand was its effect on seabirds.

"Among juveniles, urban light pollution may be mistaken for moonlight, attracting and disorientating species like Cook's #petrel or Hutton's #shearwaters.

"This could cause birds to crash land or collide with buildings, and they may become injured or grounded in cities.

"She said people could help by turning off outside lights when they were not needed, and asking their local councils to consider more directional or dimmer lighting in public places. [I would recommended warmer lighting as well. Too much blue is unnatural!]

"Associate Professor Kristal Cain from the School of Biological Sciences at the University of Auckland said more research was needed to find out how light pollution affected survival and reproduction.

"This paper used bird song data collected by thousands of volunteers globally, and measured when birds started singing in the morning and when they stopped for the night.

"It found that in brighter areas birds started singing early and continued later into the night than in dark areas.

" 'Most of the bird song was collected in #NorthAmerica and #Europe,' Cain said. 'We still need to do similar work in the rest of the world to see how widespread these patterns really are. The manu of #Aotearoa are quite unique in many ways."

" 'Importantly, all this #ArtificialLight is not good for us either.'

"People could do things like closing curtains and planting trees in urban areas to contain some of the light."

8 Reasons You Should Always Turn Off Your Porch Light at Night

Flip the switch.
By Louise Parks
Published on August 20, 2025

Number 8: Harms #Wildlife and Reduces #StarVisibility

"We share this planet with our animal friends, and our actions have consequences. 'Leaving exterior lights on overnight can confuse animals, like birds and insects, and disrupt their natural behaviors,' says Harshbarger. For example, porch lights left on in abundance can disrupt natural migratory paths for birds, wreaking havoc on wildlife. 'It also causes light pollution, making it harder to see stars and harming the environment,' according to Harshbarger.

" 'Constant night lighting creates ‘light clutter’ that breaks up natural dark cycles in the neighborhood,' adds Nimela. “This messes with everyone’s sense of time, throws off wildlife, and reduces the chance of stargazing entirely.' No chance of seeing the Milky Way? No way.' "

Grrrrr... #Starlink tries to block #Virginia’s plan to bring #FiberInternet to residents

#SpaceX wants more money, asks Trump admin to reject state's #broadband grant plan.

Jon Brodkin – Aug 14, 2025

"Starlink operator SpaceX is fighting Virginia's plan to deploy fiber Internet service to residents, claiming that federal grant money should be given to Starlink instead. SpaceX is already in line to win over $3 million in grant money in the state but is seeking $60 million.

"Starlink is poised to benefit from the Trump administration rewriting rules for the $42 billion #Broadband Equity, Access, and Deployment (#BEAD) grant program. While the Biden administration decided that states should prioritize #fiber in order to build more #FutureProof networks, the Trump administration ordered states to revise their plans with a 'tech-neutral approach' and lower the average cost of serving each location."

Some evidence that human fear of darkness affects tolerance of lower street lighting levels in urban spaces, although the strength of the effect strongly depends on an innate “trait anxiety” (i.e., a predisposition to feel anxious across many situations) in certain individuals.

BioMed CentralHot days and light-polluted nights increase nighttime activity of the diurnal tiger mosquito (Aedes albopictus) - BMC Environmental ScienceBackground Global urbanization and climate change introduce significant environmental challenges such as light pollution (a.k.a., artificial light at night or ALAN) and rising temperatures. Both factors have the potential to disrupt the temporal activity patterns of many species, including key disease vectors such as the tiger mosquito (Aedes albopictus). This study aimed to investigate whether light pollution and elevated daytime temperatures prompt Ae. albopictus to shift their activity towards the night, a typically less active period for these day-active mosquitoes. Methods During the summer of 2023, we enrolled 58 households across the Greater St. Louis area (MO, USA) and used traps to collect and monitor the host-seeking and mate-seeking activity of the tiger mosquito. Sites were selected across a light pollution gradient, and temperature was measured using field loggers and extracted from local weather stations. We analyzed the relationship between light pollution and daytime temperature with nighttime mosquito abundance using generalized additive models (GAMs) with negative binomial distributions, including percent impervious surface as a covariate. Results We found a pronounced increase in mosquito activity at night at sites with high levels of light pollution. Percent impervious surface only explained a small portion of the variance in nighttime abundance, while both daytime mosquito abundance and the interaction between light pollution and temperature explained substantial portions of the variance in nighttime abundance. The significant interaction between light pollution and temperature indicates that the effect of light pollution on nighttime mosquito activity strongly depends on temperature. Specifically, nighttime mosquito abundance was low at lower levels of light pollution but increased significantly starting around 3500 µcd m⁻², but only when daytime temperatures approached or exceeded the critical thermal maximum of females. Conclusions Our findings suggest that rising temperatures and light pollution can extend the temporal activity period of Ae. albopictus. This adjustment in activity could buffer Ae. albopictus against rising temperatures, create novel nighttime vector-host encounters, and inform vector control strategies within urban environments.

I love the example of the church. There are so many churches in Europe that have terrible, wasteful floodlights, and they are missing out on the opportunity to do something much more creative with much lower environmental impact.
