How to watch the NTU Falcon Cam on PC, Mac, iOS and Android

Unfor­tu­nate­ly the uni­ver­si­ty streams as RTMP, which gen­er­al­ly requires Flash to stream in a web brows­er. Bizarrely their approach has been to advise view­ers to enable Flash, poten­tial­ly open­ing 1047 ways for view­ers to get hacked. I’ve noticed many peo­ple hav­ing prob­lems watch­ing the cam­eras, so I wrote this short guide on a way to play the cam­eras:

For PC and Mac

  1. Down­load and install VLC Play­er
  2. Down­load this file (right click and Save As):
  3. Open VLC Play­er, Media -> Open File, and open the file you down­loaded
  4. Press the track skip but­tons to change cam­eras

For Android smartphone

  1. Install the VLC Play­er app from Google Play
  2. Open the VLC Play­er app
  3. Press ‘Open MRL’ from the left menu, and type:
  4. I find it can take a good 30 sec­onds for the stream to open. Play con­trols appear if you swipe up from the bot­tom of the screen. It isn’t very intu­itive


  1. Install the VLC for Mobile app from the App Store
  2. Open the VLC Play­er app
  3. Press ‘Net­work Stream’ from the left menu
  4. Type this URL into the box at the top:
  5. Press ‘Open Net­work Stream’
  6. Press ‘ntucalconcams.m3u’ which should now be added to the list
  7. The cam­era streams should now show. It can take 30 sec­onds to start. Use the track skip but­tons to change between the three cam­eras.


Hope­ful­ly in the future NTU will either stream direct­ly to a HTML5 com­pat­i­ble for­mat, or set up a live stream­ing con­ver­sion serv­er.

Hope this helps peo­ple enjoy watch­ing the fal­cons.


Rock, Paper Scissors

I lis­tened to an inter­est­ing pod­cast today, explor­ing the game Rock, Paper, Scis­sors, pre­dic­tion pat­terns and game the­o­ry.

Being clever isn’t an effec­tive way of win­ning, as peo­ple are rarely per­fect deci­sion mak­ers. The Nash equi­lib­ri­um is only rel­e­vant to domains with per­fect deci­sion mak­ers. So it is impor­tant to con­sid­er the choic­es of oth­ers.

In the pod­cast, it was men­tioned that from large datasets:

The biggest chunk of peo­ple will think one step ahead, the next biggest chunk of peo­ple will think total­ly ran­dom­ly, the next biggest chunk of peo­ple will think two steps ahead, and a small num­ber of peo­ple will go beyond two steps.

It also con­sid­ers crowds and groups influ­enc­ing deci­sions.

Happy New Year — 2012

I wish every­one suc­cess and good health for 2012.

For me, 2011:

  • Taught myself elec­tron­ics and Arduino, and built two time­lapse cam­eras
  • Learnt and used NGinx with HTTPS, and HAProxy
  • Learnt Android pro­gram­ming
  • Per­fect­ed my 360 pho­tog­ra­phy, achieved sur­round sound, and my first pro­fes­sion­al 360 pho­to­graph
  • Con­tin­ued busi­ness suc­cess

Excit­ed for the oppor­tu­ni­ties 2012 brings.
