WELCOME TO NOSTR
To join Nostr you need a profile, but it is not the usual one that a company generates and manages for you. You create it yourself, no permissions are required.
Nostr is a different experience from the beginning: because there is no central authority taking care of who is who, each user is identified by a cryptographic keypair; don’t worry about the tech slang, it is just a strong password that you will have to keep safe.
This wizard is one of the many ways to bootstrap a Nostr profile that you can later use in other apps. We help you to create your keypair and safely manage it in a few steps. Are you ready?
What is Nostr? ELI5
The aim of ELI5 (explain me like I‘m 5) is to explain difficult things simply. This is urgently needed in our high-tech world, because only by understanding the technologies can we use them properly and develop them further.
I‘m starting my series with Nostr, a relatively new internet protocol.

High Performance Battery: Redefining batteries
Welcome to a new basic technology.
Engineered to store energy in a safer and more sustainable way.
Ready to enter a new era?
The technology: A solar panel that produces hydrogen
Air contains moisture. The water molecules in the air are captured by the panel when the airstream enters the device.
Solhyd technology can be applied in many locations around the globe. Only the most arid places on Earth are expected to be too dry for hydrogen panels to work efficiently.
SmallTechnology Foundation: About
We’re Laura Kalbag and Aral Balkan (and Oskar the huskamute). We live and work in Bray, Ireland.
Since 2014, we’ve been advocating for regulation of surveillance capitalism, investment in ethical alternatives, and carrying out research and development on ethical alternatives.
After leaving the UK and moving to Ireland, we set up the Small Technology Foundation with the mission to evolve the Internet so each one of us can own and control our own place on it.
We strive to follow the principles of Small Technology in our work.
We don’t take money from surveillance capitalists and we exist thanks to the support of individuals like you.
What is the Small Web?
The Small Web is for people (not startups, enterprises, or governments). It is also made by people and small, independent organisations (not startups, enterprises, or governments).
On the Small Web, you (and only you) own and control your own home (or homes).
Small Web applications and sites are single tenant. That means that one server hosts one application that serves just one person: you. On the Small Web, we do not have the concept of “users”. When we refer to people, we call them people.
Another fundamental difference between the Big Web and Small Web is that on the Big Web we trust servers and distrust clients whereas on the Small Web, we distrust servers and trust clients. We treat servers as dumb delivery mechanisms. The client – under the control of the person who owns the site or app – is the only trusted environment.

UNBOUND
Unbound is a validating, recursive, caching DNS resolver. It is designed to be fast and lean and incorporates modern features based on open standards.
To help increase online privacy, Unbound supports DNS-over-TLS and DNS-over-HTTPS which allows clients to encrypt their communication. In addition, it supports various modern standards that limit the amount of data exchanged with authoritative servers. These standards do not only improve privacy but also help making the DNS more robust. The most important are Query Name Minimisation, the Aggressive Use of DNSSEC-Validated Cache and support for authority zones, which can be used to load a copy of the root zone.

How to Change Your DNS on Any Device
(20.01.2024)
A Domain Name System (DNS) matches human-friendly domain names to computer-friendly IP addresses.
When you type in a domain name like cyberghost.com, for example, your web browser sends the request to your ISP via your router. Your ISP refers the request to its default DNS server. The DNS server then supplies the relevant IP address so your browser can load the appropriate page.
A DNS also saves a local copy or cache of sites you’ve recently visited on your device for quick and easy reference.
It seems like a streamlined service; what could go wrong? Check the following reasons why you should change your DNS.
Known DNS Providers
Here we suggest a list of trusted DNS providers.
Was ist DNS over TLS?
Bei DNS over TLS (DoT) handelt es sich um ein Protokoll zur verschlüsselten Übertragung von DNS-Anfragen (Domain Name System). Üblicherweise wird die Namensauflösung im Internet unverschlüsselt über UDP übertragen. Bei DoT erfolgt hingegen die Zuordnung von Domains und den dazugehörigen IP-Adressen verschlüsselt über das Transport-Layer-Security-Protokoll (TLS). Hierdurch ist die Übertragung vor Abhörversuchen, Manipulationen und Man-in-the-Middle-Angriffen geschützt.
The birth of the Web
On 30 April 1993, CERN put the World Wide Web software in the public domain. Later, CERN made a release available with an open licence, a more sure way to maximise its dissemination. These actions allowed the web to flourish.
The OpenDNSSEC project
OpenDNSSEC is a policy-based zone signer that automates the process of keeping track of DNSSEC keys and the signing of zones. The goal of the project is to make DNSSEC easy to deploy. The project is Open Source and intends to drive adoption of Domain Name System Security Extensions (DNSSEC) to further enhance Internet security.
DNSSEC History Project
DNS Security Prehistory
Few technologies are more critical to the operation of the Internet than the Domain Name System (DNS). The initial design of DNS did not take security into consideration, which was not unusual for protocols designed in the early 1980s. At the time of its development, and for many years there after, DNS had functioned without many formal security mechanisms, thereby making it vulnerable to DNS spoofing and other malicious attacks.
Determining the Need for DNSSEC
[What drove the work? Big picture issues. Surely this includes the demonstrations of cache poisoning by Steve Bellovin and Tsutomu Shimomura in the early 1990s and the similar work by Dan Kaminsky in 2008, but it may include much other activity.]
(…)
Cache Poisoning
The earliest known security problem with DNS was DNS cache poisoning, also sometimes called DNS spoofing. DNS cache poisoning happens when a DNS server downstream from the authoritative one returns incorrect data to queries for names or IP addresses. This occurs because an attacker has ‘poisoned’ the cache of the downstream DNS server to return the malicious response. DNS cache poisoning is a subset of a group of problems computer scientists often classify as cache invalidation.
This problem, known to the Computer Science Research Group(CSRG) at U.C. Berkeley since 1989, was finally described in a paper by Steve Bellovin in 1993. Bellovin initially put off publishing the paper out of fear the information would be exploited.
(…)
Concern over DNS cache poisoning, specifically that the leak would become publicly known, existed from 1989 to 1995.

With DNS, users can type host names such as “USC-ISIF” instead of “10.2.0.52.” Every Address would have information from specific to general.

Deswegen wurde 1983 der Informatiker Paul Mockapetris damit beauftragt, eine Lösung zu finden. Mockapetris verwarf alle bisherigen Ansätze und entwickelte sein eigenes System, das er auf den Namen “DNS” taufte. Auch wenn sich das Domain Name System seitdem deutlich verändert hat, funktioniert es in seinen Grundzügen immer noch so wie vor knapp vierzig Jahren.

About: OpenDNSSEC was created as an open-source turn-key solution for DNSSEC. It secures zone data just before it is published in an authoritative name server.
Why DNSSEC?
Many internet protocol hinge on DNS, but the data in DNS caches has become so vulnerable to attack that it cannot be relied upon anymore. The added authenticity in DNSSEC makes sure that such attacks have no effect.
That is, if
– Zones are verified. Easy-to-deploy software for DNSSEC-aware name resolving (and caching) exists, for example Unbound or properly configured Bind9.
– Zones are secured. Easy-to-deploy solutions for DNSSEC did not yet exist, at least not in open source. Hence the OpenDNSSEC project.
More on the problems with DNS and about deploying DNSSEC can be found in this white paper.

Wärtsilä launches world’s first large-scale 100% hydrogen-ready engine power plant
(18 June 2024)
Wärtsilä is addressing this need through its new hydrogen-ready engine power plant, which can be converted to run on 100% hydrogen. The new engine power plant is a significant step beyond existing technology, which can run on natural gas and 25 vol% hydrogen blends.
Successful production of hydrogen panels
(November 15, 2024)
Solhyd not only develops technology to produce hydrogen from air and sunlight. We also develop methods to produce that technology in a cost-effective and reliable manner. Efficient production, with cost reductions driven by scale benefits, will eventually lead to the lowest cost approach to make hydrogen from solar energy.
We took the first step in that process this year.
Green energy breakthrough thanks to KU Leuven scientists
(02 October 2019)
For over a decade, Professor Johan Martens and Drs. Tom Bosserez, Jan Rongé and Christos Trompoukis have been developing a ‘solar hydrogen panel’, i.e. a solar panel that can create hydrogen from the water vapour in the air. Using sunlight, moisture taken from the air – i.e. no liquid water – is split into hydrogen on the one hand, and oxygen molecules on the other.
The panel is able to directly convert no less than 15 per cent of sunlight into hydrogen gas, Which is a world record

TLS 1.3: Slow adoption of stronger web encryption is empowering the bad guys
(April 6, 2020)
Asymmetric encryption is used during the “handshake”, which takes place prior to any data being sent. The handshake determines which cipher suite to use for the session – in other words, the symmetric encryption type – so that both browser and server agree. The TLS 1.2 protocol took multiple round trips between client and server, while TLS 1.3 is a much smoother process that requires only one trip. This latency saving shaves milliseconds off each connection.
