Malgré dix ans de recherche sur l'amplification, les médias mainstream reproduisent les mêmes erreurs qu'en 2016.
Couvrir des figures toxiques pour les critiquer leur offre l'audience qu'elles n'auraient jamais obtenue seules. Le New York Times, Piers Morgan donnent une tribune à ceux qui n'ont "aucun pouvoir numérique" — jusqu'à ce qu'on leur en donne un.

3. There was a strong focus at #Disinfo2025 on foreign actors / #FIMI from #Russia, not so much on #disinfo attacks from internal actors, the far right, #Trump, or #BigTech billionaires.
4. There was hardly any discussion of the role of #BigTech social media's business models, algorithmic #amplification, and lack of due diligence in the spread of #disinformation. One ex-US #Army guy claimed "platforms are not the problem," information "is moving on its own." Does it though, does it? 🤦

Subject: complaint about cargo-culting audiophools and the #marketers that exploit them
I saw a new #scam yesterday. Well, new to me. It's probably been around forever.
There are many, many #fraudulent products and ideas out there that target the self-described "audiophiles". And because such #audiophools never do double-blind tests, they always convince themselves of just how well the #scammy products work ("you are the easiest person for you to fool").
Examples of long standing:
Super-thick "oxygen-free copper" #cables for #speakers or #interconnects, being sold at 100x the price of regular cables.
Electrically shielded fiber-optic cables (!).
Paint pens to colour in the outer edge of CDs and DVDs.
Systems to run your equipment from #batteries so as not to contaminate them with that dirty mains #AC.
#Tubes / #valves instead of solid-state #amplification.
... and on and on.
Well, yesterday I was looking for some opamps (tiny little chips, used everywhere), and came across a place selling replacement #opamps for use inside stereo equipment. You can get perfectly good designed-for-audio opamps of good quality for a few bucks each. Upgrading your equipment to better opamps sometimes made sense in the 1970s, but not now. The ones used from the factory are fine.
But no, this one was selling fancy opamps, designed for *RF* use, not audio, which normally cost $10-20 each, in fancy little metal packages, for hundreds of dollars apiece.

Sharing a translation from the German because it's so important:
"62% of Germans are afraid of the AfD. They fear that the party will destroy democracy. But almost all major parties only serve the (oversized and fictitious) concerns of 24% AfD voters. The concerns of the Germans are NOT taken seriously. They're being reinforced."#GermanPol #AfD #AlterativFürDeutschland #amplification #roleOfTheMedia #Germany #ReconnectingConsequencesToCauses

"The type of oscillation generated in our study resembles ‘wave packets,’ which is a concept used in various communication technologies, including wireless communication, where information is sent in the form of modulated wave packets rather than continuous waves."

While I can get behind advocacy for better public funding for hearing aids, their peripherals, and the services to support them, and I find the US federal initiative interesting, I find it puzzling that you’re so enthusiastic about AirPods as a specific solution.
Hearing support through is essential for auditory-verbal communication, and appropriate amplification is key to learning, development and social integration of children and for maintaining cognitive function in older adults, however I feel that the AirPods as a solution are being overhyped.
First off, the DIY automated audiograms you cite have been available online for iPads since at least 2017. They are great as you say for convincing people to see an audiologist, and I was able to help a friend to persuade their parent to do that a couple of months ago with an iPad synced to Sony headphones. Nothing to do with AirPods.
More, I really have to push back on the notion that “a hearing aid is basically just a microphone in your ear.”
If you’re talking about the old primitive analogue ones such as the NHS was dispensing in the UK in the 1970s, that’s true. All they did was amplify input from an external mic across the board through a little speaker in the ear. And most older adults who received those refused to wear them because they were so primitive.
But modern hearing aids are complex computers on your ears. It’s not clear from what you’ve shared that AirPods will fill in all, or even their key features.
- They amplify based on the individual’s audiogram - hearing loss profile - not at a constant volume - and those profiles need to be checked and updated regularly with scrutiny by a trained audiologist.
- They have diverse filtering options to choose from based needs, for example to make it possible to hear in a gym or arena or to stand using them outside with wind noise.
- The better ones stimulate areas of the brain shown to be important to mitigate cognition issues when hearing loss is age related.
- Different models are better suited for different ages and activities and tolerances for insertion in the ear - e.g., while doing sports activities.
So we have complex small computers that need regular software updates and physical repair. This is more complex than simply buying a pair of drug store eyeglasses to help reading. The audiologists are technicians as well as health care practitioners and these specialized services naturally go together.
Last point price - the amounts you quote for $5-6 k per ear were typical Canadian prices 10-12 years ago. Prices are still expensive but half that now for high end models. It’s still a huge cost for any individual or family, especially when extras to link devices by Bluetooth or even just cleaning products or batteries are factored in. But overstating the cost doesn’t advance advocacy in my view.

#UK #SocialMedia #InternetRegulation #HateSpeech #Amplification #Riots: "The last question is whether we need more law anyway. There’s already a lot of law out there. When the dust settles, we’ll see that people have been prosecuted under public order legislation, under malicious communications legislation, for communications offences, and so on. Punishing those who actually riot is not going to be a problem. Punishing those who used social media to instigate these acts is not likely to prove a problem either.
Punishing those behind the acts is another matter. It seems notable to me that of the many proposals being mentioned by politicians so far, none seem to be even trying to hold those whose rhetoric, both online and offline, have made it all happen, to account. Until and unless they do, the rest is all irrelevant."

#SocialMedia #HateSpeech #ContentModeration #Amplification #Algorithms #EU #Meta: "Meta’s secret internal research, leaked by whistleblower Frances Haugen, confirmed that its algorithm artificially pushes political extremes: if a person in the US followed only verified conservative news accounts, they were soon recommended extreme conspiracy content. This polarising force – and the capture of ad revenues that once sustained journalism – has derailed our political dialogue.
We have powerful tools to fix this problem. Recommender algorithms need intimate data about users to operate. But intimate data, including data that may reveal a person’s political views, enjoy particularly strong legal protection in the GDPR. Before feeding these data to their recommender algorithm, digital platforms are required to pass a very strict test: a person must be warned about the consequences, asked to switch the system on, and then separately be asked to confirm that this is really what they want to do."

The #Batagay or #Batagaika crater in Siberia often referred to as the "Doorway to the Underworld" or the
"Gateway to Hell" is a
#permafrost #megaslump in Yakutia, Russia.Dimensions vary by source, but the site covers around 192 acres (78 hectares)
and stretches two thirds of a mile (one kilometer) in length.Logged of trees in the 1960s, its walls reach a depth of around 180 feet (55 meters)
and expose 650,000 years of geologic history.Since first spotted in the 1960s by surveillance satellites, the crater has grownfrom an insignificant gully to a massive depression at an accelerating rate.
According to Sarah Cadieux, Sr. Lecturer and Associate Director of Environmental Science of Rensselaer Polytechnic Institute,
the crater area increased by almost three times from 1991 to 2018.The Batagaika crater isn’t a crater at all,
it’s a #retrogressive #thaw #slump, a type of terrain called #thermokarst that occurs in areas underlain by permafrost.No longer cooled by forest cover, the slump has become a self-sustaining #feedback #loop,
a portion of the ecosystem which has tipped into a new state.This is not an isolated case, but rather a rapidly growing problem in the Arctic as
💥it warms three to four times the rate of the rest of the planet since 1979.Called Arctic or polar #amplification, this phenomenon is a well established fact measured by instruments,
confirmed in climate computer models,
and reinforced by paleoclimate records.Powerful anecdotal evidence occurred in the scorching heatwave of 2020 that saw the Russian town of Verkhoyansk
which lies north of the Arctic Circle hit a stunning 38° C (100.4° F) on June 20.2020 also saw overall temperatures in the Siberian basin rise to nearly 11° F above normal,
shocking scientists and releasing #ancient #methane
not from ancient organic material,
but from #limestone.Elevated methane in wetlands was expected, but not from #outgassing #rock.
A year later in 2021 Europe’s climate change service Copernicus Sentinel satellites recorded 118° F (48° C) in the Sakha Republic of Arctic Siberia,
and records continue to fall with temperatures over 100° F in 2023 as reported by CNN. -

Melting Arctic Sea Ice Threatens Polar Bears
[the_ad id="30587"]KAKTOVIK, ALASKA —In the Arctic, the impact of climate change is happening at an accelerated pace, with temperatures rising two to four times faster than the global average.
“It’s called the polar amplification,” explains Vladimir Romanovsky, a geophysicist at the University...

In summary, the key #impact is that the #study finds evidence that #Twitter's #algorithm may contribute to increased affective #polarization and amplification of emotionally charged content by selectively highlighting divisive tweets, even though it optimizes for user engagement. This highlights the need to better incorporate #user stated preferences into #algorithms to reduce #amplification of #problematic #content.

#SocialMedia #Amplification #Algorithms: "Research on amplification has been held back by a lack of consistent definitions, and a corresponding shortage of practical metrics. In part, this is because “amplification” involves many moving pieces. We propose relative algorithmic amplification to emphasize the need to choose a baseline (relative) and factor out user behavior (algorithmic).
This definition has the great advantage of being clear about what the quantity to be measured actually is. But as the above discussion shows, that doesn’t mean it’s easy to measure. If “amplification” is something different from “distribution” we need to answer “amplified compared to what?” And if we want to use “amplification” to understand the effect of algorithm design, we need to be able to separate it somehow from user behavior, both in the short run and the long run. It may seem that our preferred definition brings in a lot of complexity – but this is a feature, not a bug. Amplification is an inherently complex idea, so it’s better that we use a definition that tells us where the difficulties lie."

I am definitely giving up trying to promote my writing on #birdsite. And that’s not because I don’t recognise the rules of the game there.
But precisely because I understand the rules of the game #twitter is pressing on me to shape my writing to satisfy it’s need for #algorithmic #amplification, I refrain from writing there.
I write about academic & complex stuff, which #twitter doesn’t give a damn about. To adapt to the ”rules” there, would hurt my message.
