" #Revolution" - The #VideoToaster #Demo #Tape ( #NewTek) - #Amiga

The 1990 video that started it all. Made you feel like you could do #video #effects like the big #television #networks. No big deal these days, but back then the barriers to entry for doing #professional video were huge.

This video comes from the #VHS tape we ordered through the mail back in 1990, just to watch all the #cool #computer #animation, and then dream about owning something like this someday.

And just like these guys did, we've used cutting edge #visual #effects #technology to enhance and upscale this video to HD, making it look better than it did in 1990. We share it here as a thank you and a tribute to the "with it" guys, and Kiki Stockhammer for creating this paradigm shift!

Open source ZeroTier is an encrypted virtual network backbone, allowing multiple machines to communicate as if they were on a single network

Bild/Foto
The code is all open source, and you can self-host the controller or use the ZeroTierOne service with either free or paid plans. Their free plan (cloud based) is robust, solid, and very consistent.

After you have two nodes connected, connecting to each other — no matter where you are or what side of any firewalls you may be on — is exactly what you would expect if you were in the same building on the same network. A primary use case is for remote access to a Home Assistant setup without needing to open up firewall ports or expose it to the internet.

The linked article explains how to get going with it.

DDoSers are using a potent new method to deliver attacks of unthinkable size

Basically, "middleboxes" used for censorship are being used for DDoSing.

https://arstechnica.com/information-technology/2022/03/unending-data-floods-and-complete-resource-exhaustion-ddoses-get-meaner/

These servers—known as middleboxes—are deployed by nation-states such as China to censor restricted content and by large organizations to block sites pushing porn, gambling, and pirated downloads. The servers fail to follow transmission control protocol specifications that require a three-way handshake—comprising an SYN packet sent by the client, an SYN+ACK response from the server, followed by a confirmation ACK packet from the client—before a connection is established.

The Hidden Life of Trees

When we pursue nature protection, we’re not protecting nature. We’re protecting ourselves.

Branching off of his bestselling book, renowned forester and writer Peter Wohlleben guides us through his most precious ideas and understanding of how trees work in this enlightening documentary. Presenting ecological, biological and academic expertise with matter-of-fact candor, Peter inspires us to really see the forest for the trees. Traveling through Germany, Poland, Sweden and Vancouver, Peter discusses, debates and explains the amazing processes of life, death, and regeneration he has observed in the woodland, and the amazing scientific mechanisms behind these wonders of which we are too often blissfully unaware.

Pingnoo – an open source cross-platform graphical traceroute/ping analyser with jitter and latency graphs for each hop

The software generates attractive graphs showing the history of each hop. The attractive visuals makes it easy to follow network routes and finding the causes of downtimes and poor network performance. This is helped by the software’s tab support, which lets you analyse multiple routes simultaneously.

The modular architecture of Pingnoo allows third parties to extend the features of the software. The main application binary is very small and only serves as a loader for components (aka plugins).

There’s support for IPv4 and IPv6. We can change the interval, and the duration of the viewport. For the latter, the default is 60 seconds, but there’s also durations of 10 minutes, 15 minutes, 30 minutes, 45 minutes, 1 hour, 12 hours, and 24 hours.

Wifi Networks Can Count How Many People Are in a Room | Gizmodo

In addition to getting the vaccine and wearing a mask, simply minimizing the size of crowds can help stop the spread of the covid-19 virus. To that end, researchers from the University of California, Santa Barbara, led by Yasamin Mostofi, have found a way to leverage a run-of-the-mill wifi network as a tool for counting the number of people in a given space.

Nebula is an open source cross-platform scalable overlay networking tool with a focus on performance, simplicity and security

It lets you seamlessly connect computers anywhere in the world. Nebula is portable, and runs on Linux, OSX, Windows, iOS, and Android. It can be used to connect a small number of computers, but is also able to connect tens of thousands of computers.

Nebula incorporates a number of existing concepts like encryption, security groups, certificates, and tunneling, and each of those individual pieces existed before Nebula in various forms. What makes Nebula different to existing offerings is that it brings all of these ideas together, resulting in a sum that is greater than its individual parts.

Nebula is a mutually authenticated peer-to-peer software defined network based on the Noise Protocol Framework. Nebula uses elliptic curve Diffie-Hellman key exchange, and AES-256-GCM in its default configuration. Nebula was created to provide a mechanism for groups hosts to communicate securely, even across the internet, while enabling expressive firewall definitions similar in style to cloud security groups.

It was developed by Slack and powers their networking worldwide.

It always amazes me when people that claim to be against de-platforming and condemn the actions of anti Free Speech companies like twitter, not only continue to post to it but when I mention Diaspora not only do they have no idea what I'm talking about, but don't even put in effort to find out. This even includes long-time tech-y type dudes.

Then again, look how long its taken bitcoin to catch the public eye compared to when it actually started, and that involves money.

NAT (Network Address Translation): Necessary Evil or Necessary Security?

The purpose of this post is to invite a discussion.

I see blogs and posts at various places on the Internet written by people who seem to see NAT as an annoyance. In fact, there are people who champion IPv6 specifically because it overcomes the "problem" of NAT. To me, NAT is a wonderful thing.

  • I love NAT. NAT allows an IP address to be shared by many devices and/or individuals. This solves the problem of having more devices than possible IP addresses, but, more importantly, it provides an NAT firewall. It's a barrier between me and the larger network that makes me safer and more private.
  • Some don't like NAT. One objection is that devices in the larger-area network can't easily initiate connections to devices in the more-local-area network. These people actually want to expose open ports to the wider network, despite the obvious safety problems this causes.

I actually see the Internet as the premier security problem in the 21^st^ century. Protecting ourselves and our devices from it is paramount. Of course big business wants everything to be "smart." In this context, "smart" just means connected to the Internet. This is madness. We all need to resist "smart" devices. Don't buy them or use them. It's just too foolish. In my country it's estimated that 1 out of 5 adults has suffered some form of identity theft. This madness needs to stop.

Yanis Varoufakis: From an economy without capitalism to markets without capitalism (video/lecture)

Abstract:

An Introduction to Pluralism in Economics Lecture Series in the Winter Term of 2019/20

Debates about economic theory are omnipresent. There is increasing doubt if complex economic relationships can be modelled precisely enough through rationality-based mathematical models. Dynamic equilibrium theory and prognoses have often been deficient to anticipate crises and upheavals in reality. This criticism is mostly brought forward by so called heterodox or pluralist economists, who have gained popularity and momentum in recent years. Even in public discourse, questions about a new economic order have become more present. Nonetheless, the progress made in research and the debates amongst scholars are not taught to undergraduate students of economics.

It is often said that new students firstly need to learn the basics before they can participate in controversial discussions. Lectures presenting different schools of thought, the history and emergence of economic thought and heterodox perspectives are mostly postponed to graduate studies - or not taught at all. The lectures series by Rethinking Economics TĂŒbingen wants to change this fact and start teaching a broad understanding of economics. What are the beginnings of the discipline and how did it depart from other social sciences? What can a philosophy of economics contribute to contemporary debates in the field? How many schools of thoughts do exist and what are their theoretical underpinnings? Are economic models the only way to do research for economists? We want to show that studying economics can be much more than integral functions, time series and indifference curves and furthermore give a prospect to what economics courses can be: controversial, interdisciplinary, multi-perspective, diversified and in tune with the latest economic developments.

Borrowing from Martha-Helen at Reddit:

Yanis starts by talking about why economics is not a natural science but a form of philosophy, giving reasons for why economics as an academic discipline needs pluralism. From there, he recalls the history of capitalism, why markets and capitalism do not go together very well (certainly in the long run) and ends his speech on what a market socialist economy could roughly look like, putting special emphasis on co-operative enterprises and a Universal Basic Dividend distributed from a social wealth fund.

A Before Times (February 3, 2020) event, just released on Youtube.

https://www.youtube.com/watch?v=9aK4OztueuE (1h30m) Intro runs 6:45 and may be skipped. Q&A @ 1:13:00.

As befits a discussion of pluralism in economics, wide ranging covering numerouus themes.

Varoufakis begins noting a key difference between physical and social sciences: "in physics, the phenomenon does not give a damn about our models ... whereas within social sciences, whether it's sociology, economics, whatever, the phenomenon really cares about our theories of the phenomenon". As I've been saying, social science's models are endogenous to the subject, in physical sciences models are exogenous.

Another item that crystalised for me was Varoufakis’s discussion of “networked companies” — rail, telegraph, telephone, broadcast, retail, middlemen, and the like. I’ve been realising for some years that all examples of monopoly (monopsony, oligopoly/oligopsony, etc.) I can think of are characterisable as networks. Seems I’m in good company.

Here’s a September 2020 article by Varoufakis that addresses the networked companies bit very close to what’s in the lecture:

Electromagnetism gave rise to the first networked companies, producing everything from power generation stations and the electricity grid to light bulbs for every room. These companies’ gargantuan funding needs begat the megabank, along with a remarkable capacity to create money out of thin air.

The agglomeration of megafirms and megabanks created a technostructure that usurped markets, democratic institutions, and the mass media, leading first to the Roaring Twenties, and then to the crash of 1929.

To re-float the financial system, central banks channelled waves of cheap liquidity to the financial sector, in exchange for universal fiscal austerity that limited spending by lower- and middle-income households.

Unable to profit from austerity-hit consumers, investors became dependent on central banks’ constant liquidity injections — an addiction with serious side effects for capitalism itself.

Consider the following chain reaction: The European Central Bank extends new liquidity to Deutsche Bank at almost zero interest. To profit from it, Deutsche Bank must lend it on, though not to the “little people” whose diminished circumstances have weakened their repayment ability.

Yanis Varoufakis, "This is how coronavirus exposed Capitalism"
https://gulfnews.com/opinion/op-eds/this-is-how-coronavirus-exposed-capitalism-1.73603500

Somewhat similar, see my own "Propaganda, censorship, and surveillance are all attributes of monopoly" (discusing communications monopolies), and earlier in Tim Bray: "You [the tech sector] might be evil":

Bray, presently at Amazon, previously with Google, Sun, and DEC, mentions the M-word: monopoly. He does not make the leap I've traversed in the past year or so of recognising that monopoly, rentierism, networks, and power, all appear inextricably linked. That is: networks (physical or logical) are monopolies, and provide economic rents, through the mechanism of power and manipulation.

DEiM25 is the Democracy in Europe Movement 2025, founded by Varoufakis.
