Ubuntu + Evolution + Exchange

By default Ubuntu does not install the EWS (Exchange Web Service) plugin for Evolution

sudo apt-get install evolution-ews

Then go into Evolution and choose the following settings:

  • Server Type: Exchange Web Service
  • Username: WINDOWS-DOMAIN\username
  • Host URL: https://webmail.company.com/owa/

Now click “Fetch URL” and it should ask you for a password and populate the Host and OAB Url correctly.

It will then try and launch Evolution but for me I had to restart for it to correctly work and then it asked me a couple of times for my windows password.

AMD ATI Graphics tearing in Chrome on Ubuntu 15.04

I had to switch to using proprietor AMD drivers as the open source ones don’t support audio via display port, but after switching, Chrome was tearing and just going completely black.

The chrome GPU page reported no hardware acceleration enabled.

So I went to Chrome Flags page and forced GPU acceleration and rasterisation

Override software rendering list -> Disabled
Enable GPU rasterization -> Force enabled on all layers
Smooth Scrolling Linux -> Enable

I’ve been using hyper.sh which is very similar except it uses Docker images inside the hypervisor. OSV looks very interesting especially the REST API for inspecting a running image.

How to connect to CloudFoundry’s Loggregator directly via WebSockets

Firstly make sure you can run the standard CloudFoundry cli:

cf logs [APP_NAME]

Then turn on tracing:

export CF_TRACE=true

You will see a HTTP request and then it will switch to a secure WebSocket:

WEBSOCKET REQUEST: [2015-04-22T11:27:22+01:00]
GET /tail/?app=[APP_GUID] HTTP/1.1
Host: wss://loggregator.[YOUR_CF_DOMAIN]:443
Upgrade: websocket
Connection: Upgrade
Sec-WebSocket-Version: 13
Sec-WebSocket-Key: [HIDDEN]
Origin: http://localhost
Authorization: [PRIVATE DATA HIDDEN]

As you can see the Authorisation header is hidden, but fear not if look in ~/.cf/config.json under “AccessToken” thats all you need ("jq .AccessToken ~/.cf/config.json"). Combine this with wscat and you are good to go:

wscat -c wss://loggregator.[YOUR_CF_DOMAIN]:443/tail/?app=[APP_GUID] -H Authorization:$(jq .AccessToken ~/.cf/config.json)
