Gleich zu Anfang habe ich mir meinen Stream so eingerichtet dass jeweils der aktuelle Spieler-Counter immer im Bild zu sehen war. Ich finde das einfach eine ganze witzige Information vor allem für LuckyV-Interessierte.
Meine ursprüngliche Implementierung war etwas kompliziert – zu kompliziert um sie einfach mit anderen zu teilen.
Daher habe ich mich entschlossen den Zähler in eine eigene Windows Applikation zu verpacken die von Streamern einfach verwendet und in OBS eingebunden werden kann.
Starten und prüfen ob die Zahl auch angezeigt wird – es sollte ungefähr so aussehen:
Man kann das nun auf zwei Wegen einbinden.
Weg 1: Fensteraufnahme
In der Applikation kann man Hintergrundfarben sowie Schriftart und Farbe konfigurieren. Wenn man das erledigt hat wie man es haben will wählt man im Quellenmenü “Fensteraufnahme” und dann das Applikationsfenster.
Diese Quelle kann man dann wie man möchte konfigurieren. z.B. mit Filtern um bis auf die Schrift alles transparent zu gestalten oder oder oder…
Weg 2: playercount.txt
Wenn die Applikation läuft aktualisiert sie ständig eine Datei “playercount.txt” im gleichen Ordner. Man kann nun OBS so konfigurieren dass diese Datei regelmässig ausgelesen und angezeigt wird.
Dazu fügt man ein “Text (GDI+)” im Quellenmenü hinzu und konfiguriert diese Quelle so dass der Text aus einer Datei gelesen wird:
Hier kann man dann auch beliebig Schriftart, Größe und Farbe konfigurieren.
Disclaimer: I’ve joined for fun and not for profit – this is a new hobby.
For about a year now I was regularly watching some Twitch streamers go along their business and it spawned my curiousity when some of them started to do something they called “GTA V roleplay”.
Grand Theft Auto V (GTA V) is a 2013 action-adventure game developed by Rockstar North and published by Rockstar Games. Set within the fictional state of San Andreas, based on Southern California, the open world design lets players freely roam San Andreas’ open countryside and the fictional city of Los Santos, based on Los Angeles. The game is played from either a third-person or first-person perspective, and its world is navigated on foot and by vehicle.
So these streamers where mostly using an alternative client application to log into GTA V online servers that where operated by independent teams to play the roles of characters they created themselves. It started to really get interesting when there is dynamics and interactions happening between those characters and whole stories unfold over the course of days and weeks.
It’s great fun watching and having the opportunity to sometimes see multiple perspectives (by multiple streamers) of the same story and eventually even to be able to interact with the streamers communities.
One such fairly big german server is LuckyV. It’s an alternative GTA V hardcore role-play server creates by players for players.
The hardcore here means: the characters are supposed to act as much as possible like they would in the encountered situations in real life.
So in order to play on this server you have to create a character and the characters background story. You gotta really play that character when on the server.
When you play it’s not just a vanilla GTA V experience. There are lots of features that are specific to the server you are playing on. Some examples are:
Communication: you are communicating with people in your vicinity directly – you can hear them if they are close enough to be heard and you can be heard when you are close to people
Jobs: there’s lots to be done. Become CEO of your own company and manage it!
Social Interaction: there’s probably an event just around the next corner happening. You are able to meet people. Crowds of people even. Remember: There are usually no non-players. Every person you see it a real human who you can interact with.
The LuckyV community made a great overview page where you can watch other people playing and live streaming their journey. It’s extensive – over 200 streamers are online regularly and the screenshot below shows a mid-week day right after lunch…
Anyhow. This is all great and fun but plot twist: I do not play it. (yet)
So what do I have to do with it except I am watching Streamers? Easy: Behind the game there’s code. Lots of code actually.
In a nutshell there’s a custom-GTA V server implementation that talks to a custom GTA V client. LuckyV is using the altV server and client to expand the functionalities and bring the players into the world.
It allows for 1000 simultaneous players in the same world at a time. So there could be 1000 people right there with you. Actually since LuckyV is about to have it’s first birthday the regular player numbers are peaking at around 450 simultaneous players in Los Santos at a time.
The whole set-up consists of several services all put together:
web pages for game overlays, in-game UI and administration tools (PHP)
a SQL database that holds the item, character etc. data
a pub/sub style message hub that enables communication between in-game UI, webpages and the gamemode
a TeamSpeak 3 server that allows players to join a common channel (essentially one teamspeak room) and a plug-in called SaltyChat that mutes/unmutes players in the vicinity and allows features like in-game mobile phone etc.
everything of the above is in containers and easily deployable anywhere you got enough hardware to run it – when there are 100s of players online the load of the machine grows almost linear – and the machine is doing it’s moneys worth then…
So after the team announced some vacancies through those streamers I watched I contact them and asked if I could help out.
And that’s how I got there working on both the gamemode code as well as helping the infrastructure become more stable and resilient.
For my first real contribution to the gamemode I was asked to implement secondary keys for vehicles as well as apartments/houses.
Up until now only the owner / tenant of the vehicle or apartment had access to it. Since this game is about social interactions it would be a good addition of that owner could hand out additional keys to those they love / interact with.
And that I did. I worked my way through the existing code base – which is a “grown codebase” – and after about 3 days of work it worked!
Most impressive for me is the team and the people I’ve met there. This current team welcomed me warmly and helped me to wrap my head around the patterns in the code. Given the enthusiast / hobby character this has it’s almost frightening how professional and nice everything works out. I mean, we developers had a demo-session with the game design team to show off what our feature does, how it works and to let them try it out to see if it’s like the envisioned it.
They even did a trailer for the feature I worked on! And it is as cheesy as I could only wished:
So far so good: It’s great fun and really rewarding working with all these nice people to bring even more fun and joy to players. Seeing the player numbers grow. Seeing streamers actually use the features and play with it – handing over keys to their partner. Really rewarding.
For the first time in the last 10ish years I am back playing a game that really impresses me. The story, the world and the technology of Cyberpunk 2077 really is a step forward.
It’s a first in many aspects for me. I do not own a PC capable enough of playing Cyberpunk 2077 at any quality level. Usually I am playing games on consoles like the Playstation. But for this one I have selected to play on the PC platform. But how?
I am using game streaming. The game is rendered in a datacenter on a PC and graphics card I am renting for the purpose of playing the game. And it simply works great!
So I am playing a next-generation open-world game with technical break-throughs like Raytracing used to produce really great graphics streamed over the internet to my big-screen TV and my keyboard+mouse forwarded to that datacenter without (for me) noticeable lag or quality issues.
The only downside I can see so far is that sooo many people like to play it this way that there are not enough machines (gaming-rigs) available to all the players that want – so there’s a queue in the evening.
But I am doing what I am always doing when I play games. I take screenshots. And if the graphics are great I am even trying to make panoramic views of the in-game graphics. Remember my GTA V and BioShock Infinite pictures?
So here is the first batch of pictures – some stitched together using 16 and more single screenshots. Look at the detail! Again – there are in-game screenshots. Click on them to make them bigger – and right-click open the source to really zoom into them.
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.
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.
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.
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.
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.
The Chaos Communication Camp is an international, five-day open-air event for hackers and associated life-forms. It provides a relaxed atmosphere for free exchange of technical, social, and political ideas. The Camp has everything you need: power, internet, food and fun. Bring your tent and participate!
This year it’s time again for the Chaos Communication Camp in Germany. Sadly still I won’t be attending. Clearly that needs to change with one of the next iterations. With the CCC events becoming highly valuable also for families maybe it’s a chance in the future to meet up with old and valued friends (wink-wink Andreas Heil).
The Chaos Communication Camp (also known as CCCamp) is an international meeting of hackers that takes place every four years, organized by the Chaos Computer Club (CCC). So far all CCCamps have been held near Berlin, Germany.
The camp is an event for providing information about technical and societal issues, such as privacy, freedom of information and data security. Hosted speeches are held in big tents and conducted in English as well as German. Each participant may pitch a tent and connect to a fast internet connection and power.
This project is a way for people to use CSS Grid features quickly to create dynamic layouts.
You can set the numbers, and units of your columns and rows, and I’ll generate a CSS grid for you! Drag within the boxes to create divs placed within the grid.
I noticed a lot of people weren’t using Grid because they felt it was too complicated and they couldn’t understand it. Grid is capable of so much, and this small generator only touches on a fraction of the features. The purpose of this is so people get up and running quickly, and create more interesting layouts.
