It seems today is 0.3 day, as I'm also releasing Carbon 0.3, my hackable performant semi-static blogging system.

This release mainly deals with technical debt as I first started this project 6 years ago as a playground for figuring out how a CMS is written from the ground up. This means there are out of date requirements, references to a Windows platform with Powershell and other such bad examples.

That said the codebase isn't in a terrible state although it will have to change significantly before it's production ready. If you know a bit of PHP then after a short study it can be customised to your needs quite easily.

So, if you're interested you can use it and quickly whip together a documentation or simple blog using only markdown files. It will produce a feed and there's even a half baked cli application and static site generation that I have to review before I can recommend it in honest.

Have fun hacking!

I've been using Traktor for years now as my deejaying solution and broadcasting tool. The one missing feature on the broadcasting side is that it can only stream directly to Icecast servers, lacking the ability to stream to SHOUTcast based servers. Most servers use the SHOUTcast streaming protocol which grew popular through the MP3 movement back around the turn of the century. We will setup a transcoding link to enable streaming to SHOUTcast servers.

This guide will focus on OS X but on a general level is also applicable to Windows users.

This replaces my previous guide at https://sites.google.com/site/traktorshoutcast/

Overview

We will need the do the following things:

1. Install Homebrew, a package manager to help set things up.(OS X)
2. Install and setup Icecast, a streaming server that will accept the Traktor stream. (aka local streaming server)
3. Install and setup LiquidSoap, a transcoder that will connect to the local stream, and broadcast it in SHOUTcast format.
4. Configure Traktor's broadcasting settings to point to the local streaming server.

Also useful is to keep the SHOUTcast stream (remote stream) details to connect to at hand (host, port, password).

1) Install Homebrew

Homebrew is a terminal package manager to add / remove / update OS X software and compile it from source code for us, so we don't have to.

Homebrew installs the stuff you need that Apple didn’t.

To install, follow the directions on http://brew.sh. Currently (as of Feb 16) that says:

1. Open a terminal window.
2. Run /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Follow any instructions about the Xcode commandline tools.

After everything is setup you can run brew update to update your formulae, brew upgrade to upgrade to their latest versions, and brew doctor to diagnose any issues with your particular installation. Keep the terminal open for the next step.

2) Install and setup Icecast

Icecast is a streaming media server which [...] can be used to create an Internet radio station or a privately running jukebox and many things in between.

We will setup the local streaming server so that we can connect Traktor and the transcoder to it.

Install

In the terminal window you left open, run brew install icecast.

If I remember correctly, everything should go smoothly and before long you'll get a message saying it's successfully installed.

Configuration

To keep the configuration files we are about to create nicely together, create a broadcast folder somewhere (I used ~/Music/Broadcast).

I have prepared a very simple configuration file for you, download it from https://gist.github.com/svandragt/f7ecb720416a68f096a1 (right click the raw button and select Download Linked File As.. and save it as icecast.xml in the broadcast folder you just created).

• This configuration file is insecure and uses the default Icecast passwords, please change them as I have done so that others on your network cannot login and disconnect your stream whilst broadcasting.
• Notice that the mount point is /traktor.ogg, on port 8000, on localhost (your own machine).
• I've taken out everything that is not necessary to keep the file as simple as possible. There are all kinds of settings you can add, see http://www.icecast.org/docs/icecast-2.4.1/config-file.html">http://www.Icecast.org/docs/Icecast-2.4.1/config-file.html

You won't have to change the contents of this file, apart from the passwords.
This configuration creates a mount point on http://localhost:8000/traktor.ogg for Traktor and LiquidSoap to connect to.

Starting and Stopping the Local Streaming Server

In the terminal window, in your broadcast folder, run icecast -c icecast.xml. It should show a few warnings but no errors, and your local streaming server is now running. Stop it now by pressing ctrl+c.

3) Install and setup LiquidSoap

Our flagship is liquidsoap, a swiss-army knife for multimedia streaming, notably used for netradios and webtvs. Liquidsoap is a powerful and flexible language for describing your streams. It offers a rich collection of operators that you can combine at will, giving you more power than you need for creating or transforming streams. But liquidsoap is still very light and easy to use, in the Unix tradition of simple strong components working together.

We will install the program and setup a flow (configuration) to connect to the local streaming server, and broadcast it to the remote stream.

It should have been simple to install using brew, but unfortunately it was not. After several days of debugging here is a working set of instructions I produced.

Install

In the terminal window you left open, we will run the following commands:

1. brew tap drfill/liquidsoap -- This enabled homebrew to install it.
2. brew install --env=std liquidsoap --with-shout -- this installs LiquidSoap using the standard build environment with shoutcast support

Grab a drink. After a while hopefully all works fine. I noticed that LiquidSoap is now recommending OPAM to install it so you could try that if this doesn't work for you. (http://liquidsoap.fm/download.html) - I have not tried it.

Configuration

As before, I have created a very simple flow. You will need to setup one flow per destination stream so if you play at multiple radio stations / SecondLife clubs then you will need multiple flows.

Download it from https://gist.github.com/svandragt/af43c07d5842c9c429d5 (right click the raw button and select Download Linked File As.. and save it as example.liq in the broadcast folder).

This time you have to edit it, to add the remote stream details. Change the following lines to suit your purposes:

• output_host = "example.com"
• output_port = 8124
• output_pass = "mypassword"

The configuration above is for broadcasting to a SHOUTcast server at http://example.com:8124 (using the password mypassword). Leave the rest of the file alone or make a copy and start experimenting LATER, see http://liquidsoap.fm/documentation.html. LiquidSoap is very powerful.

Starting and Stopping the Transcoder

In the terminal window, in your broadcast folder, run liquidsoap example.liq. It will start showing a lot of messages, and because you are not currently broadcasting also some errors. Stop it now by pressing ctrl+c.

Traktor

Start Traktor and open the Preferences menu item. Open the Broadcasting tab.

Use the following information to point to the local streaming server:

Server settings:

• Address: localhost
• Port: 8000
• Mount path: traktor.ogg
• Password: hackme (but you changed this, right)
• Format: Ogg Vorbis, 44100 Hz, 192 kBit/s (highest quality, bottom option)

You can enter whatever you like in the Metadata Settings.

In Traktor, click the broadcast button (the little attenna). It will flash because the local streaming server isn't running and therefore Traktor cannot connect to it. Whenever Icecast is running but the button is still flashing, check that the password and other connection details match.

For now, click it again to stop broadcasting.

All together now

Before you start streaming:

1. Start Icecast and keep it running.
2. In Traktor, click the broadcast button and confirm its not flashing.
3. Open another terminal window / tab in the broadcast folder for the next step.

When you start streaming:

1. Start LiquidSoap with the flow of your remote stream. Keep it running.
2. Start deejaying!

When you are finished

1. Stop broadcasting with Traktor.
2. Stop liquidSoap to let the next DJ on the stream.
3. Stop Icecast because nothing is connected to it now.

Final thoughts

I hope this helps anyone having trouble deejaying online, I enjoy it very much and if you'd like to listen to deep house / electronica, please listen to my mixes.

Steve Gibson pointed me to a guide to setting your desired privacy level in Windows 10. This version of Microsoft's operating system follows the 'always socially connected' footsteps of smartphones and therefore makes privacy assumptions. Using this guide you can check if they match your expectations.

Interesting article by Tom Phillips interviewing developers about Windows 8 and it's closed Windows Store, with this gem of a quote from Introversions' Chris Delay:

"I really don't want to see the PC becoming a closed platform. Microsoft is not a company that's able to benignly oversee that process. They will f*** it up. We'll all be doing Kinect support and 16 language versions, we'll all be supporting a Microsoft Office plug-in. It's my own worst nightmare.

[...] “The PC continues to be as relevant as it was ten years ago, despite consoles coming and going, because it is an open platform. If that changed it would be terrible.”

It's interesting times for the gaming industry, indeed.

Today a problem came up where the files on my Samba fileshare did not indicate to my Windows system that they were changed. Software that relies on this information such as TortoiseHG and SimpleLESS would not know that the file had changed. This was especially obvious with SimpleLESS which should take the .less file and process it, but wouldn’t.

This sounds like a situation where I hope some rep from Microsoft will intervene and offer the guy his reward.

This post describes a step by step guide on how to combine multiple Subversion repositories whilst keeping individual history (and commit messages).

Dumping

Exporting from pagefeedbacktool repository the /trunk/public folder and integrating that into the services repository under /trunk/public/pagefeedback:

Dump the repository including only /trunk/public as follows:

E:\\Repositories\\pagefeedbacktool>svnadmin dump .| svndumpfilter include --drop-empty-revs --renumber-revs trunk/public > ..\\services\\filtered.dump

Loading

However as pathnames are stored as part of the dump (and replacing the path with a texteditor corrupts the dump), we have to include the full path under a different parent directory:

In VisualSVN create a /trunk/public/pagefeedback/trunk/public folder structure (try without the final public if import fails) then load the dump as follows:

E:\\Repositories\\services>svnadmin load . --parent-dir "trunk/public/pagefeedback" < filtered.dump

The dump is successful but at the wrong path:

currently: /trunk/public/pagefeedback/trunk/public
should be: /trunk/public/pagefeedback/

Post-correction

Open two Windows Explorer windows with both paths side by side, select all the files that should be moved, then RIGHT click drag them to the destination folder and choose SVN Move versioned files here...

Commit from the repository root.

It is now safe to remove the trunk/public folders under /trunk/public/pagefeedback/

Commit again.

Create a smart playlist with all unplayed podcasts. By using this playlist you no longer have to find the next podcast on your iPhone whilst driving back home. Make sure that you include the smart playlist on the Podcast tab of your iPhone, iPad or iPod Touch.

Update:
Although this seemed a great solution in theory, there are some issues with this approach in practice. As diskspace on the iPhone is at a premium you will have to limit the amount of podcast data stored on your device. However, because there is not an option to keep 1 unplayed episode per podcast in the smart playlist editor you have to set the amount of diskspace used. When you have several podcasts and some are updated more frequently then others you will end up for some podcasts not being on your device and others that are continuously listened to. Therefore I opted for http://vemedio.com:80/products/instacast">InstaCast which caches 1 episode per podcast and comes with continuous playback in its latest update.

A while ago I had to normalize values in an Excel sheet where some of the values contained an asterisk (*) and some did not. However it's not immediately clear how to search for a asterisk. It turns out the escape character is a tilde so searching for ~* is the correct way to do this.

As a hobbyist music producer, I have a lot of samples of sounds. As I have decided to start organising these, I needed a quick way to fire off samples in wav and mp3 format through Windows Explorer.

So I created InstaPlay. This is a simple sound player. To install it simply unzip it in a directory that's in the path, and then associate wav and mp3 files (and whatever else you want to use) with it.  It also has a few features:

1. Just double click or run a soundfile to hear it play.
2. Nice speaker icon in system tray while a sound is playing. Double click it to quit InstaPlay and stop playback.
3. Run  another sound file to switch playback to that instead.

This program will help you categorize more efficiently as you can move the sound that's being played without pesky 'file in use' prompts.
