@Nowhereman @kattascha Ok, #Irland ist hier imho aber auch ein Sonderfall. Die Leben #BNB schon weit bevor auch nur jemand an #AirBNB gedacht hat.
In meiner Kindheit haben wir da schon BNB-Urlaub gemacht (und sind zwischendurch mit nem Hausboot den #Shannon ruf und runter geschippert) -

Dans sa dernière video avant son kidnapping par les forces d'intervention d'#Israel, Catherine Connolly, la soeur de la présidente irlandaise dénonce le hub militaire #US à #Shannon #Airport par lequel transite des milliers de soldats US en partance vers des zones de guerre.
Les #USA maintiennent environ 750 bases militaires dans plus de 80 pays, plus que n’importe quelle nation de l’histoire mondiale.

Thanks to the Limerick and Clare Amateur Radio Club for a brilliant weekend in Shannon for the @ei0irts 93rd AGM weekend.
We had a great time meeting people, chatting radio, showing off some of what we get up to in TOG, and flying the flag for amateur radio in the hackerspace world.
We’ve loads more photos from the weekend here:

Hype for the Future 142G: Unorganized Counties in South Dakota
Overview While every county located within the State of South Dakota is an official unit of government within the State, the particular counties of Todd and Oglala Lakota (formerly Shannon) within the State are identified as dependent on external counties for duties, namely the Counties of Tripp and Fall River. Even though Oglala Lakota County exists within the State of South Dakota, the community of Hot Springs within Fall River County takes the duties of the county. Similarly, Todd County […] -

Couldnt get a clear grip on your interests from your feed, so came here to say this too. Also markets ( #invisibleHand - theory of moral sentiments, and the wealth of nations) , #qualityControl, and #openBSD, I reckon. I'm delving these at the moment and it's super interesting. Also Enterprise Resource Planning software suites (specifically #ERP5 but it might prove too deep for my delving ability) and sometimes #cybernetics (which goes back to #mathematical #complexity and #communicationTheory ).

Arıkan's new solution was to create near-perfect channels from ordinary channels by a process he called “#channel #polarization.”
Noise would be transferred from one channel to a copy of the same channel to create a cleaner copy and a dirtier one.
After a recursive series of such steps, two sets of channels emerge, one set being extremely noisy, the other being almost noise-free.
The channels that are scrubbed of noise, in theory, can attain the Shannon limit.
He dubbed his solution #polar #codes.
It's as if the noise was banished to the North Pole, allowing for pristine communications at the South Pole.After this discovery, Arıkan spent two more years refining the details.
He had read that before Shannon released his famous paper on information theory, his supervisor at Bell Labs would pop by and ask if the researcher had anything new.
“Shannon never mentioned information theory,” says Arıkan with a laugh.
“He kept his work undercover. He didn't disclose it.”That was also Arıkan's MO. “I had the luxury of knowing that no other person in the world was working on this problem,” Arıkan says, “because it was not a fashionable subject.”
In 2008, three years after his eureka moment, Arıkan finally presented his work.
He had understood its importance all along. Over the years, whenever he traveled, he would leave his unpublished manuscript in two envelopes addressed to “top colleagues whom I trusted,” with the order to mail them “if I don't come back.”
In 2009 he published his definitive paper in the field's top journal, IEEE Transactions on Information Theory.
It didn't exactly make him a household name, but within the small community of information theorists, polar codes were a sensation.
Arıkan traveled to the US to give a series of lectures. (You can see them on YouTube; they are not for the mathematically fainthearted. The students look a bit bored.)
Arıkan was justifiably proud of his accomplishment, but he didn't think of polar codes as something with practical value.
It was a theoretical solution that, even if implemented, seemed unlikely to rival the error-correction codes already in place.
He didn't even bother to get a patent.

Arıkan devoted the next year to learning about networks, but he never gave up on his passion for information science.
What gripped him most was solving a challenge that Shannon himself had spelled out in his 1948 paper:
how to transport accurate information at high speed while defeating the inevitable “noise”
—undesirable alterations of the message
—introduced in the process of moving all those bits.The problem was known as #channel #capacity.
According to Shannon, every communications channel had a kind of speed limit for transmitting information reliably.
This as-yet-unattained theoretical boundary was referred to as the #Shannon #limit.
Gallager had wrestled with the Shannon limit early in his career, and he got close. His much celebrated theoretical approach was something he called low-density parity-check codes, or LDPC, which were, in simplest terms, a high-speed method of #correcting #errors on the fly.
While the mathematics of LDPC were innovative, Gallager understood at the time that it wasn't commercially viable.
“It was just too complicated for the cost of the logical operations that were needed,” Gallager says now.
Gallager and others at MIT figured that they had gotten as close to the Shannon limit as one could get, and he moved on.
At MIT in the 1980s, the excitement about information theory had waned.
But not for Arıkan.He wanted to solve the problem that stood in the way of reaching the Shannon limit.
Even as he pursued his thesis on the networking problem that Gallager had pointed him to, he seized on a piece that included error correction.
“When you do error-correction coding, you are in Shannon theory,” he says.
Arıkan finished his doctoral thesis in 1986, and after a brief stint at the University of Illinois he returned to Turkey to join the country's first private, nonprofit research institution, #Bilkent #University, located on the outskirts of Ankara.
Arıkan helped establish its engineering school. He taught classes. He published papers.
But Bilkent also allowed him to pursue his potentially fruitless battle with the Shannon limit.
“The best people are in the US, but why aren't they working for 10 years, 20 years on the same problem?” he said.
“Because they wouldn't be able to get tenure; they wouldn't be able to get research funding.”Rather than advancing his field in tiny increments, he went on a monumental quest. It would be his work for the next 20 years.
In December 2005 he had a kind of #eureka moment.
Spurred by a question posed in a three-page dispatch written in 1965 by a Russian information scientist, Arıkan reframed the problem for himself.“The key to discoveries is to look at those places where there is still a paradox,” Arıkan says.
“It's like the tip of an iceberg. If there is a point of dissatisfaction, take a closer look at it. You are likely to find a treasure trove underneath.”
Arıkan's goal was to transmit messages accurately over a noisy channel at the fastest possible speed.
The key word is #accurately. If you don't care about accuracy, you can send messages unfettered.
But if you want the recipient to get the same data that you sent, you have to insert some #redundancy into the message.
That gives the recipient a way to cross-check the message to make sure it's what you sent.Inevitably, that extra cross-checking slows things down.
This is known as the #channel #coding #problem.The greater the amount of noise, the more added redundancy is needed to protect the message.
And the more redundancy you add, the slower the rate of transmission becomes.
The coding problem tries to defeat that trade-off and find ways to achieve reliable transmission of information at the fastest possible rate.
The optimum rate would be the Shannon limit: channel coding nirvana.
