Copy, with line wrapping!

If you've been trying to copy/paste text from a multi-pane tmux session with the mouse, you've probably been pretty pissed at the blissful ignorance a terminal application has of the rodent in your hand.

The alternative, which is quote-unqoute native copy/pasting using copy-mode takes a bit to get used to. So this is one solution for copying and pasting lines from a session with correct line wrapping behaviour, albeit keyboard only.

Disclaimer

Since copy-mode has similar concepts of marks, regions, and temp buffers to Emacs .. you'll probably find it straight forward if you're familar with Emacsen. For people using vi-mode in tmux, the same still applies but obviously the default key bindings will differ alot from what I show below.

How to setup your own CA with OpenSSL

For educational reasons I've decided to create my own CA. Here is what I learned.

First things first

Lets get some context first.

An introduction to DynamoDB

DynamoDB is a powerful, fully managed, low latency, NoSQL database service provided by Amazon. DynamoDB allows you to pay for dedicated throughput, with predictable performance for "any level of request traffic". Scalability is handled for you, and data is replicated across multiple availability zones automatically. Amazon handles all of the pain points associated with managing a distributed datastore for you, including replication, load balancing, provisioning, and backups. All that is left is for you to take your data, and its access patterns, and make it work in the denormalized world of NoSQL.

Modeling your data

The single most important part of using DynamoDB begins before you ever put data into it: designing the table(s) and keys. Keys (Amazon calls them primary keys) can be composed of one attribute, called a hash key, or a compound key called the hash and range key. The key is used to uniquely identify an item in a table. The choice of the primary key is particularl

Mounting block device in lxc (specifically Proxmox 4)

1. Find devices' major & minor ID (need both dev + partition for HDD)
# ls -al /dev/sda
brw-rw---- 1 root disk 8, 0 Dec 19 11:16 /dev/sda1
# ls -al /dev/sda1
brw-rw---- 1 root disk 8, 1 Dec 19 11:16 /dev/sda1

That's 8,0 for sda and 8,1 for sda1

Installing the Cisco vWLC on KVM using virt-install

Cisco has a few different guides for installing their vWLC on KVM, but most of them focus on oVirt-style installations that are heavy on hand-crafted XML and [what appears to be] the use of OpenStack. If you're just using a plain single-host KVM setup and want to install the vWLC in a VM, this guide is for you.

Instructions

First, download the vWLC KVM installation image appropriate for your setup. I'm going to use version 8.5.171.0 (you'll have to create an account to download it), and then transfer it to your KVM server:

AndrewBobulskys-MacBook-Pro:~ andrewbobulsky$ scp ~/Downloads/MFG_CTVM_LARGE_8.5.171.0.iso 10.0.25.2:/tmp                   100%  367MB  40.7MB/s   00:09

SSH CA use-case with Vault

In this scenario we are going to set up Vault to sign SSH keys using an internal CA. We will configure the SSH secrets engine and create a CA within Vault. We will then configure an SSH server to trust the CA key we just created. Finally we will attempt to SSH using a private key, and a public key signed by Vault SSH CA.

Prerequisites

• This guide assumes you have already provisioned a Vault server, SSH host using OpenSSH server, and a SSH client machine.
• The client system must be able to reach the Vault server and the OpenSSH server.
• We will refer to these systems respectively as:
• VAULT_SERVER
