cross-posted from: https://retrolemmy.com/post/32212672

I am very happy to announce the full release of the

libre-open-source textbased, sandbox-style, storydriven, retro-style cyberpunk network-sandbox (more than a) game

Jailbreak Katana

here, today exclusively on LEMMY.

Let me first thank you, because lemmy is indeed a healthy project. The people were helpful and friendly here. The mods did their job and the overall experience is very good.

Then, let me thank all the open source projects that made this Masterpiece possible. There are too many to name them all, so - just check the dependency list of the project.

I am also speaking in the name of the artists behind this project, which you can discover on your journey throuh the ITP-network (~ the game world) - we are all very proud to be here with you today.

Yes, this is a historical moment: and like always, when a new era of art has begun, it is a moment of silence - not a big event ...

anyway - enough of the chit chat ... GOOD LUCK, HAVE FUN!

edit: due naming issues the repo has been moved to: https://codeberg.org/ennix/hypercore

sorry for the inconvenience

edit: I choose the orginal name by heart, but it could lead to future trouble ; it's better that i changed it right now.

edit:

The outpost node #1,2,3 will now switch from “release mode” to “intermediat mode” [UTC-Sun18-20] (due energy shortage)

Looks interesting, but after reading through the readme, I still clueless about the gameplay. Why does it need a container ? Is this some kind of security CTF with a story ?

[–] MalReynolds@slrpnk.net 6 points 1 week ago (1 children)

Yah, possibly interesting, but the blurb is super unhelpful.

the container build is nesssary to have a coherent build. It is quite similar to a docker app, but it just doesn't need the docker service and it builds and runs without any root access (you could build this as a guest on a linux-host and, if you have access to bwrap, even run it). Also the app is then transfereble to any other linux-system. It is astonishing simple and convenient. You can use the build-system to build cli-container-apps of your choice. unix-style[*] programming for all the different linux-systems out there is extremly difficult, because the systemes are very uncoherent, so this build-kit fixes this and also allows users to build a working app for a friend and send it per mail. (the resulting transfer-size can be as small as <5Mb [depending on your system])

Also, yes it increases the security quite a bit: only rw in the home folder of the container, just sharing network with the OS, ... and more benefits like tmpfs for all nonpermanent files (zero disk-io for those)

Also yes, it could be part of (a users) story: a described above, this can be build and transferred on servers with limited user rights (allthough bwrap is needed), but in can be indeed used to jailbreak from such a server and connect with the ITP-network. The ITP-network allows information-exchange via relay nodes, so it could used to get the right hints, even if tor is not available, but access to static-ip4/6-nodes (which should be always the case)

[*] but unix-style programming was absolutely needed for this project, because it is REAL retro-style. 90% of the tec used is from the 70's - it's a real Retro-party :D

edit: typos, more info

Definitely going to check it out when I have time, but I'm curious how it can be "sandbox-style" AND story-driven at the same time?

[–] Ennix@retrolemmy.com 1 points 1 week ago* (last edited 1 week ago) (1 children)

thx for the question: the game client is basicly a universal-networking sandbox (imagine it as networking-minecraft) the story is about node-hopping and gathering information. There is a path that leads to a pay-off (but that path will be more and more hard to find, the later you join the network)

edit: more info, typos

[–] Peruvian_Skies@sh.itjust.works 2 points 1 week ago

Seems cool. Thanks a lot for the reply.

Also, i am positivly suprised about the feedback and attention. Thank you for that. This shows that i choose the right platform for the exclusive release - (i announced it only here)

I did this for a reason: this is a fully uncomercial project (no monetization what-so-ever - ever)[*] and

it is a real underground gem, and i did not want to throw this gem into the pigpen.

this place has definitly some class - greetings ... user1

[*]i absolutly not care about mass-adoption - this is about ART

edit: typos, correction, ...

Thx again, the release was successful, no more hotfixes needed.

Before i go (you can meet me in the ITP-network then), let me give you some more information about the development and the struggle to find a worthy release platform:

development time ~6 years programming: one person + helping artists and testers.

After trying out different release-models, i thought direct binary release would be an option, but the build-kit aproach is much, much better. Because i changed the technology, i changed the release name. It was once planned to name it: Beyond the iron cycle.

Let me tell you about the title: When an old star burns out of hydrogen, it will burn helium, then lithium and so on... until it burns iron. But after iron, there is no energy gain in the fusion. The star immedeatly stops burning core-fuel and the radiation-pressure drops to zero, but the radiation-pressure is the only thing that keeps the star from collapsing. The drop is so immedeate and therfore the implosion of the star, that - if the star is a big one - the implosion will cause a supernova.

The core of a civilisation is the artistic myhology: if that myhology is not sufficiant and burns out - until the iron cycle, the civilisation will collapse. The best thing to do, if such a thing is about to happen, is ... to be beyond the limit of the iron cycle. And for that task, the elders of cybernetics planned for the hypercore ,- those elders, who invented and realized the POSIX-standard. It is so very well forged like a Katana - you will understand that, if you mastered it - and you will, i am sure - otherwise you won't Jailbreak the iron-cycle-technology.

GOOD LUCK and have fun!
