#38c3 is starting .... Infos about some scheduled delta sessions and a group invite for further maybe more spontaneous things at delta.chat/38c3 Please repost a bit ....and we'll see to write up some impressions and discussions afterwards in turn ... Our plans and roadmaps still have some fluidity and congress will likely modify 2025 intentions further :)
Teaching mathematics through informalism is like driving in a fog. One sees dim figures in the distance, and every once in a while some of them suddenly appear clearly, but usually everything is veiled and mysterious. It’s dangerous to drive in the fog, especially in a strange territory, and one must drive slowly. Even so, one may not always be sure where one is. Teaching rigor and precision, provided it is done without the veil of complexity interfering, burns away the fog, leaving everything crisp and clear and making it possible to drive faster and to enter uncharted lands.
When it is very clear what steps are legal, you can go further. Just like in programming, strong type systems will let you attempt things that you don't dare without them because you will probably fail somewhere without noticing.
So, you're using decentralized non-corporate-owned social media because you don't want your online identity and activity tracked and held by some corporation, and even possibly a government-influenced owner (TikTok?).
I've opened an #XMPP (#Jabber) messaging server, which is based on the same principles as whatever application you are reading this on. XMPP is completely decentralized, open source, free, and volunteer run.
Also, neither member identity nor messages are stored on the server. There is no centralized control over the network. You sign up by first choosing a server. Your ID looks like an ActivityPub ID (example: support@chat.between-us.online).
Besides end-to-end message encryption, there's optional #OMEMO on-device encryption. No centralized messaging app (other than Signal) offers an encryption option this strong. There's video calling, file transfer, and both public and private chat rooms/groups. There are many messaging applications available for all operating systems.
You provide no personally identifiable information when you sign up, not even an email address. You only pick your ID and provide a password (which cannot be changed or recovered as the server does not keep identity information, so don't lose it and be sure it can't be guessed). If you delete your account, through the messaging app, there is no record of your account having existed on the server.
If interested, you can sign up on the messaging application (use chat.between-us.online as the server) or via the website at between-us.online, which also provides additional information about XMPP and how to use it.
A note about #Matrix. Don't @ me about Matrix. This message is only to announce an XMPP (Jabber) server option. I am not advocating XMPP over Matrix. I use Matrix as well. It ticks all the same boxes. This is just an announcement about an XMPP server.

"how to create a stratum-1 NTP Server using a Raspberry Pi utilizing GPS and PPS, and get time within 100 nanoseconds of real time, directly from the atomic clocks located in the GPS satellites above your head. The best part about this guide is that this will work with no internet."
This post details how to create a stratum-1 NTP Server using a Raspberry Pi utilizing GPS and PPS, and get time within 100 nanoseconds of real time, directly from the atomic clocks located in the GPS satellites above your head.
also I'm a woman but I really felt the paragraph about the purpose of life becoming more relaxed. Not physically, I'm exhausted lol, but otherwise yeah what was I otherwise shooting for?
hm. That sounds sort of tragic. I'm no tradwife. And if people choose childlessness I think that's a perfectly good choice, if not actually *less* selfish!
I do definitely agree that there's power and contentment in working towards something outside of yourself, not for your own betterment.
That of course doesn't have to be kids, or military service, or religion. There are so many good things we can do.

This train just arrived from Poland. I wonder what speed limit applies there (not relevant since the track via Poland is so broken that it does not support more than 40 kmph anyway) and whether the Polish part between Germany and Czechia is considered German or Czech since the train is apparently not certified for Poland.
It is considered Czech. Here is the German version of the rules for the cross-border section I’m assuming you are referring to: dbinfrago.com/resource/blob/12…

Hi, all. My mom has been gone for nearly 15 years but her pies live on and our legend! She made the absolutely best pies in the whole world. So, I got brave and made my first pumpkin pies from scratch, including the crust. She had the old 1946 edition of the Joy of Cooking book. It comes in 30 volumes from BARD. I eventually found that old pie crust recipe that she used in that book. I followed the recipe on the can of pumpkin, adding in nutmeg. I also used cream instead of evaporated milk per one of the suggestions on the can. Tooting my own horn here, the pies were absolutely amazing. The secret is not handling the dough, using shortening and a little butter, and a little ice water for perfectly flaky piecrust. I used this wonderful Mrs. Anderson's piecrust bag. You shake your dough into a ball and place it inside the bag and zip it shut. Then, you can roll the dough inside the round bag . When you're done, you zip open the bag which lies flat, put the pie plate upside down over the dough, and flip it over. Awesome! Just thought someone might find this helpful! See link below!

In October, some very good friends gave me the awesome gift of an aerobatic flight with Upright Aviation Academy near Toronto. Since I am totally blind, the standard video that is provided as part of the experience wouldn’t work for me. As a Christmas present, my partner @ChristineMalec arranged for the video to be audio described. The description was written by J. J. Hunt and voiced by Christine Malec. youtu.be/OkTAvXxYbEI
Microsoft and OpenAI have a very specific, internal definition of artificial general intelligence (AGI) based on the startup's profits, according to a new
Lemme translate this for you. When they say that the definition of an “AGI” is that it will generate “$100 billion in profits,” what they really mean is that they want “AGI” in order to avoid paying $100 billion to employees. gizmodo.com/leaked-documents-s…

This should be illegal. Microsoft Is Forcing Its AI Assistant on People—And Making Them Pay msn.com/en-us/technology/tech-… The Copilot is based on OpenAI. I believe it is time to take Microsoft to court for unauthorized use of others' work as well. They abuse their dominance on desktops and in office spaces. Just like Google, they need to be split into 100 parts and punished deeply for beaching everyone else privacy by stealing customers' data to train their shity AI.

@SuspiciousDuck Tiež asi nie je potrebné všetko brať doslovne a vážne 🙃 Pointa je, že ľudia evidentne nevedia, že tie čísla znamenajú stupne. A ak si ľudia nevedia zistiť takú hlúposť, asi si nebudú vedieť zistiť aj dôležitejšie veci. Ťažké myšlienkové pochody, ja viem.
@SuspiciousDuck To je úplne jedno, termostat funguje na princípe, že sa nastaví teplota a tú udržiava. Rovnako funguje termostatická hlavica na radiátore. Ak je nastavená na 20 °C a v izbe je 23 °C, radiátor nehreje.
@SuspiciousDuck Principu fungovania hlavice chapem a vedel som o tom. Ale pochybujem, ze hlavica namontovana na radiatore - zdroji salaveho tepla v jej okoli - ma ponatia aku teplotu mam na druhom konci velkej izby. Cize presnost takej regulacie je otazna. Keby bolo nejake bezdrotove cidlo aj na druhej strane izby, tak by som tomu veril viac.
@js @SuspiciousDuck A ja nechápem čomu nechápete. Termostatická hlavica nie je žiadna veda, a ak niekto nevie ako funguje, asi ťažko bude vedieť odhaliť ako funguje ssmer. That's all.
@js @SuspiciousDuck Nechápem ten argument o hlúposti a IQ, nikde som nič také nepísal. Ak máte nízke sebavedomie, komplexy si ventilujte inde, ďakujem pán anonym.
@js @SuspiciousDuck To bol humor? Nechcete ísť robiť stand-up, keď ste taký "vtipný"? Tam by ste ale nemohli byť za anonyma, takže to nebude nič pre vás. Ono pokojne stačí nekomentovať za každú cenu cudzie príspevky, tak jednoduché to je.
Nemuzu si odpustit, nebot jakozto strojovy asketik - kazdej kdo ma profilovej obrazek korporatni-apple mrdky je pro me obeti rezimu. rad bych vas zachranil, ale vy budete uz asi ztracenej.
@js @SuspiciousDuck Keby vás to tak veľmi zaujímalo, tak mám jedine MacBook, keďže Windows je shit a Linux mi žiaľ na moje potreby nedostačuje. Ale je veľmi dobre vedieť, že hodnotíte ľudí na základe profilovej fotky a technológií ktoré používajú. Neviem čo ste potom vy, keď tu vypisujete v anonymite, ale hrdina rozhodne nie ste.

After my spectacularly popular post on Alfvén waves, there's nothing to do but write a much less popular post on the math behind them. People say magnetic field lines in a plasma can act like stretched rubber bands: if they're bent, they try to straighten out. There's a Wikipedia article on this idea, which is called 'magnetic tension':
They start with the equations of 'ideal magnetohydrodynamics' where you have a plasma with velocity vector field 𝐯, pressure p, density ρ and electric current vector field 𝐉 in a magnetic field 𝐁. It's called 'ideal' because we're assuming the plasma conducts electricity so well that the electric field is zero.
One of these equations, called the 'Cauchy momentum equation', says the plasma accelerates due to two forces:
the gradient of pressure, or more precisely −∇p, and
the force caused by the magnetic field, which is 𝐉 × 𝐁 as usual - this is called the Lorentz force.
They then do some fun vector calculus manipulations. Assuming |𝐁| is constant everywhere, they find a term in the force whose magnitude is the curvature κ of the magnetic field line, which points to the center of curvature of the magnetic field - where you approximate the magnetic field locally as going around a circle of radius 1/κ. See the picture to understand what the hell I just said.
I think I follow the calculation, but this is a force on the plasma, right? Not the magnetic field line per se! So why do they interpret it as the field line wanting to straighten out? If we knew 𝐯 is proportional to 𝐁 that would make sense, but they don't say anything about that.
