The /r/roguelikedev challenge for Unity: Parts 0 and 1

EDIT: Please note that the Unity pricing debacle happened shortly after the original release of this introductory post and I elected not to continue this or any other work with Unity. I’m leaving this abandoned. Feel free to take what’s here and run with it if you want. I’m following along with a YouTube video that demonstrates making a Roguelike in Unity, following the methodology […]

Rendering Furigana in native Javascript

I got very used to writing Japanese with Furigana in Obsidian with the help of a plugin that took something like {漢字|かん|じ} and rendered it into the appropriate <ruby> and <rt> tags. I wanted a minimal javascript that could do the same without relying on a platform. So I adapted the code from the plugin and made it.

DeepRacer European Seaside Circuit Waypoints

I’ve been getting into AWS DeepRacer, and in wanting to build a model to compete in the current competition, I wanted to get an idea of the waypoints so I could reward certain behaviors in turns and straightaways. You can run a 5 minute model with print(params[‘waypoints’]) somewhere to get them back in the logs, formatted as a list of tuples. I took the set, […]

Use nested traversal groups to allow access to ABE-enabled grandchild folders.

Say you have the following structure: \\DOMAIN\DFS\Folder1\ <– UserA can access this folder. \\DOMAIN\DFS\Folder1\Folder2 <– UserA has no privileges on this folder. \\DOMAIN\DFS\Folder1\Folder2\Folder3 <– UserA has modify access to this folder, subfolders and files. \\DOMAIN\DFS\Folder1\Folder2\Folder4 <– UserA has no privileges on this folder. With ABE, the UserA will not see Folder2 even though Folder3 is something they do have access to. So permissions are added […]

Use GPO to change the default behavior of potentially malicious file extensions.

If you’re like me and don’t have direct control of your own email filtering, or want to go a step beyond, you’re going to want a way to prevent non-PE viruses from running. Software Restriction Policies are good for this if you’re using them in a whitelist capacity, provided that you’ve also added the extension to the Designated File Types. From a blacklist standpoint it’s […]

DangItBobby.ps1 – Remotely disable a NIC given only a username.

So I have a code offering today, which I’m calling DangItBobby.ps1. It lets you remotely disable the NIC of a computer given only the username that is logged in. In essence, when in the middle of a ransomware infection, and you see that the owner of all the files is changing to Bobby, you run the script and provide credentials of a local admin account. […]

Quick Tips: Share Permissions do more than you think.

While rebuilding a piece of my lab for file server and DFS services, I had an odd set of symptoms. I had a user in a security group that was not set to be able to change permissions, and no ability to take ownership, in the NTFS permissions. Yet they were able to add permissions to give others elevated access, or even elevate their own […]

Ransomware is the future.

When I first started fighting ransomware in late 2013, I had a premonition that this was something serious. While CryptoLocker was rather easily defeated in the enterprise and ultimately killed by killing the botnet, media outlets and tech sites ran with the story. It showed this small group making millions and millions of dollars. Guess what? More people started writing ransomware. Cut to now. Ransomware-as-a-service is […]
