How to install cGit on Nginx (Ubuntu server)

Step-by-step installtion of cGit on nginx without funky rewrite rules.

Pre-requisites

This is for

Sometimes it is useful to route traffic through a different machine for testing or development. At work, we have a VPN to a remote facility that we haven't bothered to fix for routing, so the only way to access a certain machine over that VPN is via an SSH tunnel to a machine that is reachable over the VPN. Other times, I have used this technique to test internet-facing requests against sites I am developing. It is pretty easy, and if you don't use firefox regularly, you can treat Firefox as your "Proxy" browser and other browsers can use a normal configuration (Although you can also configure an entire system to use the proxy, other articles exists that discuss this potential).

Open a terminal

Install QEMU on OSX

QEMU requires brew in OSX, so we need to install brew first.

Installing Brew

To install brew we need to have the developer tools enabled in our system. In order to install those tools, we have two options.

Download Xcode form the AppStore
In your terminal run the following command: xcode-select --install

Overview: running crc on a remote server

This document shows how to deploy an OpenShift instance on a server using CodeReady Containers (crc) that can be accessed remotely from one or more client machines (sometimes called a "headless" instance). This provides a low-cost test and development platform that can be shared by developers. Deploying this way also allows a user to create an instance that uses more cpu and memory resources than may be available on his or her laptop.

While there are benefits to this type of deployment, please note that the primary use case for crc is to deploy a local OpenShift instance on a workstation or laptop and access it directly from the same machine. The headless setup is configured completely outside of crc itself, and supporting a headless setup is beyond the mission of the crc development team. Please do not ask for changes to crc to support this type of deployment, it will only cost the team time as they politely decline :)

[My company] Incidents

This repository contains incident reports for all [my company] products and services.

How to document an incident?

Copy the template.md file to a new file named YYYY-mm-dd-title-of-incident.md, eg. 2021-09-08-database-outage.md. Make sure the date is correct for UTC rather than your local time zone, for California staff this might mean the incident happened "tomorrow". Then fill in all the fields in the template and create a Pull Request. The [my team] team will review and merge it.

What counts as an incident?

Making a Reddit Upvote Notifier

The Arduino Yún's ability to connect to the Internet introduces many new possibilities to traditional Arduino development, such as capturing data from the web and making use of it inside of a sketch.

This project will demonstrate this ability by monitoring the number of upvotes accrued by a Reddit comment thread and alerting the user when new upvotes are added.

Many companies offer application programming interfaces (APIs, for short) that allow third-party programs to access their data. Reddit, for example, provides an API that gives detailed information and statistics for posts, comment threads, and users.

This project uses a Python script on the Yun's Linux side to read the current upvote count from a comment thread using Reddit's API. A skech running on the Arduino side will track this number and display a notification message on an LED matrix every time a new vote is added.

Create Root CA and Server Certificate

Create the Root Certificate (Done Once)

Create private networks with libvirt

I assume that you have a running debian wheezy host with libvirt and qemu/kvm installed. You need two guest VMs for this. The first guest will get the IP 192.168.100.2 and the second will get 192.168.100.100. All following commands must be run with sudo or under root.

Internal Network

We create a new network named internal with libvirt and use it with the IP

Simple journal with vim

So how would you use your text editor to make a day notes?

For vim I end up using simple approach:

have a ~/docs/journal/ directory where I keep yearly journals in asciidoc format (one can use markdown of course).
have a mapping to quickly open a journal ready to enter you thoughts, notes or a todos for a day.
