Today in #electronics I built the world's worst Direct Conversion Receiver, for the AM broadcast band

It sounds very poor and low volume, but it definitely works, I can receive both of the two local stations at 630kHz and 800kHz

The LO is my signal generator

I tried adding a RF amp to fix the low volume but it resulted in breakthrough of the stronger station and heavy distortion

also tried amplifying the audio between LPF and LM386 without success




The kitties are acutely interested in my project.

#ICE arrests #superintendent of #Iowa’s largest school district

By Zoe Sottile, Priscilla Alvarez, September 27, 2025

Excerpt: "The school district and #DHS presented starkly divergent portraits of [Superintendent #IanRoberts]. DHS described him as a 'criminal alien' and suggested he was a public safety threat. But at a news conference after his arrest, board president of #DesMoines #PublicSchools Jackie Norris said the superintendent was 'an integral part of our school community' who 'has shown up in ways big and small' for students and staff. And Roberts disclosed his weapon charge, related to a hunting rifle, when he was hired, a district spokesperson told CNN.

"The arrest spurred a protest outside the federal courthouse in Des Moines. '#Education, not #deportation / Free Dr. Roberts,' read one sign carried by a demonstrator, according to footage from CNN affiliate KCCI. Local education and immigration advocacy groups have rallied behind the superintendent."

Donald #Trump on Saturday blamed a former ally for recommending someone who he would then nominate for a key role.

Trump earlier on Saturday pledged to target his own former #FBI director, #ChristopherWray, in a fiery #SocialMedia post regarding what he dubbed the “#January6th hoax.”

Das Bild zeigt ein steckbriefartiges Poster mit dem Titel "Anarchistische Saboteure – Scheuer/Dobrindt-Bande –". Es handelt sich um eine Veröffentlichung der Bundesrepublik Deutschland, die drei Männer als steckbrieflich gesucht ausgibt. Die Männer sind Andreas Franz Scheuer (geboren am 26.09.74 in Passau), Alexander Dobrindt (geboren am 07.06.70 in Peißenberg) und Peter Ramsauer (geboren am 10.02.54 in München). Der Text beschreibt sie als Saboteure, die die Bahninfrastruktur der Bundesrepublik Deutschland zerstört haben und andere Straftaten begangen haben. Für Hinweise, die zur Ergreifung der Gesuchten führen, ist eine Belohnung von 100.000 Euro ausgesetzt. Die Verfolgung ist nicht für Beamte erforderlich, sondern erfolgt unter Ausschluss des Rechtsweges. Ein Warnhinweis am Ende des Posters lautet: "Vorsicht! Diese Täter schrecken nicht vor der Verschwendung von Milliarden zurück!"

“All a ‘true ActivityPub server’ is for is storing data, fanning out subscriptions and collecting incoming data for you to view. #ActivityPub was originally designed so that all of the data presentation layers—Mastodon, PeerTube, Pixelfed—would be specialized clients communicating with the generic server. But the first popular apps cut out the client-to-server part of the protocol, so people think you need a separate identity for every client application. news.ycombinator.com/item?id=4…
in reply to Helge

Having tried to build a generic ActivityPub server, I can confirm: this is very difficult, maybe impossible. The server needs to understand the payloads -- in order to generate collections, for example. And security implications of allowing arbitrary activities are not quite clear.

However, I think a modified version of ActivityPub protocol could support generic servers.

Do you have a sense of what you feel would need to be modified with ActivityPub to make it work?

@zoul I really want a generic server. In that case I would have to start developing one of my own?

A generic server that has support to Mastodon, Lemmy and Peertube API would be awesome

full ack.
We are working heavily towards a generic server and in deed it is super important what Helge decribes but anyway, we need to come together.

original:
„the client APIs necessary to make this a reality haven't seen much development“

But many people want this.
We should change that now and meet.
After organizing the first official Confs conf.tube/c/apconf_channel/vid… (tons of videos) I advised the EU for DMA and DSA and then Client To Server was eye-opening for them.

My last Talks (e.g. together with funder at fediday) and those after had been in German but when we showed the AP Client2Server boardgame at Public Spaces it was english video.publicspaces.net/w/9USsJ… 😀

So, if anyone is interested in a nice dev. meeting about this topic apart from the new taskforces, please comment here !

in reply to @reiver ⊼ (Charles)

@xmppbrasil One thing that may be required is a removal of side effects.

For example, when a server processes Accept(Follow) activity, it is supposed to add the actor to the following collection. ActivityPub specification describes it as a "side effect". In order to do this, the server must understand the meaning of Accept(Follow) and how following collection works.

To avoid this, clients could generate Add(target: following) activity whenever they generate an Accept(Follow) activity. The implicit action becomes explicit, so a server would only need to know how to process generic activities like Add and Remove.

@helge @badrihippo @zoul

in reply to silverpill

@silverpill @reiver @xmppbrasil @helge @badrihippo i think with the way you're describing this case, it would really end up being a collection server or endpoint, right? that makes sense if there's a requirement to dynamically page collections. if you're willing to accept static collections, then it simplifies things greatly

but you could still keep side effects if you somehow signaled which clients attached to which inboxes and what they do. a "default client" can manage AP side effects

in reply to infinite love ⴳ

@silverpill @reiver @xmppbrasil @helge @badrihippo problem with side effects and multiple clients is that you need to coordinate actions or otherwise make everything idempotent and order-independent. typical mastodon monolithic case can be thought of as a single client force-attached for every actor on the server with no option to attach other clients.

Data Shows That AI Use Is Now Declining at Large Companies




It's that time of year again: make sure to get your COVID-19 shots! It's not just the right thing to do for public health: it's an act of defiance against RFK Jr, who is desperately trying to deprive Americans of vaccines so diseases (like measles) can spread.
There's a lot of confusion over COVID-19 vaccine availability after the anti-science crackdown by the guy with the literal brain parasite. What does it mean that the shot is "not recommended" for most Americans? Will health insurance companies not pay for it? Will pharmacies not offer it?
Here in Texas, I went to an HEB pharmacy and got it. I didn't have to provide health insurance information: it was free. I'm unclear on if I would have gotten it without a qualifying condition. Your mileage may vary, and this is a situation that could change rapidly, but I recommend going to your local pharmacy and trying to get it while you can.

A imagem é uma comparação humorística entre um "Hacker na natureza" e um "Membro da equipe vermelha no escritório". Na parte superior, há uma imagem de um leão majestoso, com uma manada densa e um olhar sereno, sentado em um gramado verde, representando um "Hacker na natureza". Na parte inferior, a mesma imagem do leão é modificada para representar um "Membro da equipe vermelha no escritório". O leão agora tem tatuagens, incluindo um leão na lateral do corpo, o logotipo do PlayBoy e outros desenhos, além de um coque na cabeça. A imagem sugere que, assim como o leão é um predador poderoso na natureza, um membro da equipe vermelha é um especialista em segurança cibernética, capaz de enfrentar desafios e proteger sistemas.

It has finally come to my attention today that putting a # keyword in the subject/CW field does not work for search and explore functions in Mastodon.

And I see now that was issue #699 from 2017 and closed as won't fix (falsely as "completed"). Every revival is closed as "not planned".

WTF? CWs count against character limits. Why not treat them as if they are just like message text?

I met some friends for Oktoberfest today. When I arrived, the sky was pure blue, and I was pleased to see my favorite color in this tree. When my Bavarian friend arrived, she was pleased to see the blue and white Bavarian flag, under a blue sky with little white clouds. It was a perfect day for eating outdoors. And after we finished, the clouds rolled in.
