Friend OS, a modular, fully-customizable operating system accessible via any device that can support a modern web browser, or Friend’s Android and iOS apps. Friend OS leverages Internet and blockchain technologies to offer all the features of a commercial operating system, but one that gives you access to a secure and private cloud-based virtual desktop anytime, anywhere, no matter what hardware or software you use.
So what does this all mean? It’s apparently a web application scaled up to behave and be used like an operating system. It encapsulates an application and directory/filesystem like concept and essentially lives in one of your browser windows.
As long as you’ve got a supported browser, all your apps and data will be accessible through this. They claim.
It’s interesting as there is a lot of open source in there and even some docker effort made to get it running. Seems abandoned / not updated at the time of writing, but it’s a nice concept to begin with anyways.
Current generations of RaspberryPi single board computers (from 3 up) already got WiFi on-board. Which is great and can be used, in combination with the internal ethernet or even additional network interfaces (USB) to create a nice wired/wireless router. This is what this RaspAP project is about:
This project was inspired by a blog post by SirLagz about using a web page rather than ssh to configure wifi and hostapd settings on the Raspberry Pi. I began by prettifying the UI by wrapping it in SB Admin 2, a Bootstrap based admin theme. Since then, the project has evolved to include greater control over many aspects of a networked RPi, better security, authentication, a Quick Installer, support for themes and more. RaspAP has been featured on sites such as Instructables, Adafruit, Raspberry Pi Weekly and Awesome Raspberry Pi and implemented in countless projects.
This really is going to be very useful while on travels. I plan to replace my GL-INET router, which shows signs of age.
There is a free and well integrated OpenVPN client for iOS devices already. And as much as this one works quite well it’s also lacking some comfort features that are now made available through alternative iOS client implementations of OpenVPN.
OpenVPN is an open-source commercial software that implements virtual private network techniques to create secure point-to-point or site-to-site connections in routed or bridged configurations and remote access facilities. It uses a custom security protocol that utilizes SSL/TLS for key exchange.
Meet Passepartout. The iOS OpenVPN client that comes with lots of comfort features. Of main interest for me is that Passepartout is aware of the connection you’re currently using and can adopt it’s VPN tunnel status accordingly.
Passepartout is a smart OpenVPN client perfectly integrated with the iOS platform. Passepartout is the only app you need for both well-known OpenVPN providers and your personal OpenVPN servers.
“Shepard’s Pi” is one continous song that lasts for 999,999,999 hours, or about 114 years.
Canton Becker’s music generating algorithm composed this music using the first one billion digits of pi (p). Each digit (3.1415…) determines four seconds of music, supplying the “turn signals” used to determine every musical expression.
Because the numbers in pi never repeat, each of the million hours of “Shepard’s Pi” music are in fact unique. By fast forwarding to some distant moment in the song, you are virtually guaranteed to find yourself listening to something that nobody else including Canton himself has ever heard before.
Unlike some other efforts this doesn’t just render SwiftUI Views as HTML. It also sets up a connection between the browser and the code hosted in the Swift server, allowing for interaction – buttons, pickers, steppers, lists, navigation, you get it all!
In other words: SwiftWebUI is an implementation of (many but not all parts of) the SwiftUI API for the browser.
To repeat the Disclaimer: This is a toy project! Do not use for production. Use it to learn more about SwiftUI and its inner workings.
I am back again and developing some smaller APIs for my own use.
As I am learning a new programming language and framework (SwiftUI) and for my little learning project I need to also implement a server backend. Implementing a RESTful service is quite straight-forward but for testing and UI prototyping I actually want to do some testing before really setting up the server side.
To easily test RESTful calls without actually implementing anything I found that Reqres is a quite useful tool to have in the toolbelt:
Apart from some pre-set-up API endpoints with dummy data (like users, …) it also features a request mirror service.
With that you can simply throw a JSON document into the general direction of Reqres and it will put a timestamp on it and return it right away.
User space network drivers on Linux are often used in production environments to improve the performance of network-heavy applications. However, their inner workings are not clear to most programmers who use them. ixy aims to change this by providing a small educational user space network driver, which is gives a good overview of how these drivers work, using only 1000 lines of C code. While the language C is a good common denominator, which many developers are familiar with, its syntax is often much more dicult to read than that of more modern languages and makes the driver seem more complex than it actually is.
For this thesis I created a C# version of ixy, named ixy.cs, which utilizes the more modern syntax and additional safety of the C# programming language in order to make user space network driver development even more accessible. The viability of C# for driver programming will be analyzed and its advantages and disadvantages will be discussed.
The actual implementation (with other programming languages as well) can be found here.
While recording a podcast episode we briefly touched on the topic of bulletin board systems and how we both had operated our own FidoNet BBS in the 90s.
To create a bigger reflux of thoughts:
Synchronet Bulletin Board System Software is a free software package that can turn your personal computer into your own custom online service supporting multiple simultaneous users with hierarchical message and file areas, multi-user chat, and the ever-popular BBS door games.
Everything there to set-up a BBS. Maybe I really need to get out a backup of my old BBS and bring it back online?!
Today I learned that the Apple iPhone re-purposes the IMAP protocol to implement the voice mail feature.
By sniffing the network traffic it was possible to examine the IMAP protocol revealing username and the corresponding hashed password (which allows to repeat a successful login) and of course all voicemail files. We want to highlight, that all the voicemail files have been transferred unencrypted.
Think of this: You go to the movies. Bad movies mostly. And there are 3 of your friends next to you and constantly commenting the movie – in a funny way.
Since MST3k had ended a long long time ago the people behind it have started to do the same with current movies. And this they called “Rifftrax”:
Mike Nelson, Bill Corbett and Kevin Murphy, the former stars of Mystery Science Theater 3000, create commentaries for B-movie oddities and Hollywood blockbusters. It’s like watching a movie with your funniest friends!
Their catalog has grown from 0 in 2006 to over 222 full length feature movies and much much more shorts.
If you have never experienced their art: Give them a try. You’ll probably laugh a lot!
HACK LIKE A PROGRAMMER IN MOVIES AND GAMES! GeekTyper was inspired by the various media where hacking is usually portrayed incorrectly. Simply randomly mash your keyboard and code will be simulated on your screen.
This is hilarious! :-) I’ve had way to much fun poking keys while trying it out…
Of course there’s also a screensaver that you can install. Recommended for office use. Not recommended on airplanes and other public spaces.
I’ve just checked with a real person. I’ve used the Visual Studio skin and typed away. Oh the aww.
And what reminded me of this astonishing achievement.
Think of this: You are flying at >34k miles per hour. You are >18.5 billion miles away from earth. (It’ll take >16 hours at light speed one-way trip from earth to you). And on top, you are still able to send data back to earth at 159 bytes per second.
If you, like me, are looking into new emerging tools and technologies you might also look at Wireguard.
WireGuard® is an extremely simple yet fast and modern VPN that utilizes state-of-the-art cryptography. It aims to be faster, simpler, leaner, and more useful than IPsec, while avoiding the massive headache. It intends to be considerably more performant than OpenVPN. WireGuard is designed as a general purpose VPN for running on embedded interfaces and super computers alike, fit for many different circumstances. Initially released for the Linux kernel, it is now cross-platform (Windows, macOS, BSD, iOS, Android) and widely deployable. It is currently under heavy development, but already it might be regarded as the most secure, easiest to use, and simplest VPN solution in the industry.
This guide will walk you through how to setup WireGuard in a way that all your client outgoing traffic will be routed via another machine (server). This is ideal for situations where you don’t trust the local network (public or coffee shop wifi) and wish to encrypt all your traffic to a server you trust, before routing it to the Internet.
Browsers can do many things. It’s probably your main window into the vast internet. Lots of things need visualization. And if you want to know how it’s done, maybe do one yourself, then…
So, you want to create amazing data visualizations on the web and you keep hearing about D3.js. But what is D3.js, and how can you learn it? Let’s start with the question: What is D3?
While it might seem like D3.js is an all-encompassing framework, it’s really just a collection of small modules. Here are all of the modules: each is visualized as a circle – larger circles are modules with larger file sizes.
Let me introduce you to a wonderful concept. We are using these movies as backdrop when on the stepper or spinning, essentially when doing sports or as a screensaver that plays whenever nothing else is playing on the screens around the house.
What is it you ask?
The thing I am talking about is: Walking Videos! Especially from people who walk through Tokyo / Japan. And there are lots of them!
Think of it as a relaxing walk around a neighborhood you might not know. Take in the sounds and sights and enjoy. That’s the idea of it.
If you want the immediate experience, try this:
Of course there are a couple of different such YouTube channels waiting for your subscription. The most prominent ones I know are:
Tocotronic is one of the bands I listened to during my teens/twenties. That dates me, that dates the band.
It’s very german. You’ll find their music on most streaming platforms. I recommend starting with the albums “wir kommen um uns zu beschweren” and “es ist egal aber”.
Anyhow. Now one member of the band starts a podcast!
Jan Müller ist seit über 25 Jahren Mitglied der Band Tocotronic. Er ist mit dem Format des Interviews bestens vertraut und kann sich als Fragender gut in die Perspektive seiner Gäste hineinversetzen. Die persönliche Auswahl seiner Gesprächspartner*innen bildet die Grundlage für authentische Gespräche, die stets von Interesse und Respekt geprägt sind. Mit “Reflektor” startet Jan seinen ersten Podcast.
We consolidate location and information of wireless networks world-wide to a central database, and have user-friendly desktop and web applications that can map, query and update the database via the web.
So what’s my use-case? Apart from the obvious I will make use of this by finding out more about those fellow travelers around me. Many people probably to the same as me: Travel with a small wifi / 4g access point. Whenever this accesspoints shows up in scans the path will be traceable.
I am curious to see which access point around me is in the million-mile club yet…
The PixelFed project seems to gain some traction as apparently the first documentation and sources are made available.
PixelFed is a federated social image sharing platform, similar to instagram. Federation is done using the ActivityPub protocol, which is used by Mastodon, PeerTube, Pleroma, and more. Through ActivityPub PixelFed can share and interact with these platforms, as well as other instances of PixelFed.
Whenever we arrive at a place that we have not been before it is important to get properly connected to the internet.
Finding wifi SSIDs and typing passwords is tedious and prone to errors. There is an easier way of course!
The owner of the wireless network can generate a QR code that you can easily take a photo of and your phone will automatically prompt you to log into the wireless network without you having to type anything.
On your phone it looks like this:
To generate these QR codes that contain all information for visitors/new users to connect this simple tool / online generator can be used:
Ever wanted to create a cool QR code for your guests? But never wanted to type in your WiFi credentials into a form that submits them to a remote webserver to render the QR code? QiFi for the rescue! It will render the code in your browser, on your machine, so the WiFi stays as secure as it was before (read the code if you do not trust text on the internet :-))!
Don’t worry: your access point information is not transferred over the internet. As this is open source at the time of writing the data was held in HTML 5 local storage on the local browser only and not transferred out.
