GGUF quantizations overview

Which GGUF is right for me? (Opinionated)

Good question! I am collecting human data on how quantization affects outputs. See here for more information: ggml-org/llama.cpp#5962

In the meantime, use the largest that fully fits in your GPU. If you can comfortably fit Q4_K_S, try using a model with more parameters.

Circumventing Deep Packet Inspection with Socat and rot13

Circumventing Deep Packet Inspection with Socat and rot13

I have a Linux virtual machine inside a customer's private network. For security, this VM is reachable only via VPN + Citrix + Windows + a Windows SSH client (eg PuTTY). I am tasked to ensure this Citrix design is secure, and users can not access their Linux VM's or other resources on the internal private network in any way outside of using Citrix.

The VM can access the internet. This task should be easy. The VM's internet gateway allows it to connect anywhere on the internet to TCP ports 80, 443, and 8090 only. Connecting to an internet bastion box on one of these ports works and I can send and receive clear text data using netcat. I plan to use good old SSH, listening on tcp/8090 on the bastion, with a reverse port forward configured to expose sshd on the VM to the public, to show their Citrix gateway can be circumvented.

Rejected by Deep Packet Inspection

I hit an immediate snag. The moment I try to establish an SSH or SSL connection over o

OpenBSD/octeon EdgeRouter Lite

This is a nifty little device for under £100 suitable for a home router.

I am using one running OpenBSD 6.8 for my AAISP PPPoE connection (avoiding the supplied VMG1312-B10A which has a number of issues).

Installation

I bought a SanDisk 16GB USB stick as there were reports the supplied USB stick isn't particularly reliable, plus it's nice to keep it separate in case of backup or selling the device in the future.

Download the OpenBSD miniroot68.img file system and dd(1) it, for example on macOS (assuming /dev/disk2):

MacOS for Windows users: overcoming the annoyances

Introduction

For a long time Windows user, starting using Mac can be an exercise in frustration and keeping your nerves at bay. Many things don't work as expected, need to be activated in some ways, keyboard shortcuts are non-existent or wildly different.

This page is a living reference of a Windows long-timer trying to do basic stuff on a Mac. If you see an easier way to achieve certain things, don't hesitate to drop a comment.
