Long shot: Can anyone here help me with configuring a Cisco 7821 phone so I can connect to a non-Cisco SIP provider? It seems that this is not officially supported but kind of works for some people with the specific model I have. But I've failed adapting any of the XML configuration files that I found online. And the console logs from the phone are not really helpful to a non-expert. #voip #cisco #sip

I've been watching a few coding videos on youtube lately. I have to say, this is much more enjoyable both from an entertaining and an educational point of view than one might expect.

Here's an example where someone who is normally writing C code tries out Swift for the first time. I can very much relate to most of the reactions.

Could someone please vibe-code a tool that monitors my keystrokes in vi and then suggest faster alternatives for the most common patterns?

Mathematicians are threatening to boycott the field’s largest, most prestigious gathering this summer
if it takes place in the U.S., as currently planned.

Every four years since the turn of the twentieth century,
the International Congress of Mathematicians (ICM) has brought together mathematicians from all over the world to share the latest breakthroughs and plot the field’s future.

Famous speeches delivered at the congress have gone on to redefine entire subfields of math.

The ICM is also where math’s most hallowed prize, the Fields Medal, is awarded.

This July, the ICM is slated to take place in Philadelphia
—the first time in 40 years that it’s been held in the U.S.

Now a petition to move the event elsewhere is circulating among mathematicians.

It cites the recent American military actions in Venezuela and Iran,
the suspension of visas from 75 countries
and the continued presence of federal Immigration and Customs Enforcement (ICE) agents across major U.S. cities
as contrary to the ICM’s goal of fostering “a sense of international unity amongst mathematicians.”

As of this writing, more than 1,500 mathematicians have signed the petition,
which states that they plan to boycott the event if it isn’t moved outside the U.S.

The list of signatories includes many of the field’s most prominent names,
more than 50 of whom have spoken at previous congresses.

Unpopular opinion: What if we don't restrict ourselves to do things that have "value".

🛰️ 'Miracle': Europe reconnects with lost spacecraft

「 The lost spacecraft had been "tumbling" when an ESA team in Spain "saw that some sunlight is actually hitting the solar panels," Aschbacher explained.
They seized the chance, using this small amount of power to re-establish a connection.
The spacecraft's solar panel is now facing the sun, allowing it to charge its batteries 」

'Miracle': Europe reconnects with lost spacecraft

The European Space Agency announced Thursday it has re-established communication with a spacecraft that is part of its Proba-3 mission, after losing contact with the satellite a month ago.

Delighted to see our WISPIT team announce the second directly imaged exoplanet from the WISPIT 2 system! Led by Chloe Lawlor (Galway) with Richelle van Capelleveen (Leiden), we also have a spectrum of the inner, more massive planet, showing carbon monoxide features. ☄ #exoplanet #astrodon https://www.eso.org/public/news/eso2604/

This is why I like working on small N-body simulations. No amount of money you throw at more cores, GPUs, or "AI" can make them faster.

Looks like Avenza Maps is going down the enshittification route. They will now charge $50/year to let you import maps.
