Coding width – via “Is it common to print out code on paper?” – Programmers Stack Exchange

Posted by jpluimers on 2017/01/25

I don't often read code, but when I do, I print it.

I don’t often read code, but when I do, I print it.

For I a very long time, I’ve been formatting code until about 130 characters width and recently remembered out why:

… remember printing in landscape allowed 132 characters.At Uni, I used to regularly print my code on green bar paper…

It got back memories of working on VT102 terminals and Hercules Graphics Cards adapters doing VAX-VMS (FORTRAN and Pascal) and DOS (Turbo Pascal) programming. The VT102 could do 132 columns (the VT52 only 80) and it was no coincidence that most HGC could do 132 columns as well.

Printing was usually on green-bar paper (in Dutch “zebra-papier”) which was 132 columns wide in landscape form on most line printers.

Some notes and links on hacking a Philips TVs TCP ports

Posted by jpluimers on 2017/01/25

In my case this is about a Philips 42PFL7676H TV, but this likely applies to many Philips TVs from the 2009-2012 era.

According to nmap, these ports are open:

1925/tcp open unknown syn-ack
2323/tcp open 3d-nfsd? syn-ack
49153/tcp open upnp syn-ack Philips Intel UPnP SDK 1.4 (Philips Smart TV; UPnP 1.0; DLNADOC 1.50)

TCP port 1925 is actually implementing the jointSPACE REST API over HTTP which has some nice documentation (also locally on your TV).

PCremote implements this and is easy to install: just download (or git clone) the html locally or to a web-server and try it, or even easier: browse to the site. You can even use it on your Raspberry Pi. There is also support for jointSPACE it in agocontrol.

Two nice threads about it from the Philips support forum:

TCP port 2323 seems to be the voodooport which should enable you to do DirectFB Voodoo.

Jean-Marc Harvengt (software engineer at Philips) showed a nice demo (see video below) on using VooDoo. I wish he had published the source code.

TCP port 49153 also hosts an HTTP server. The base URL I could find information about is It seems that nmrDescription.xml has to do with DLNA and upnp.

Later on I found that my brothers 32PFL7675H TV should also support JointSPACE, but that it had to be activated:

AFTER upgrading to the new firmware, jointSPACE NEEDS TO BE ACTIVATED by entering the following digits sequence while watching TV (WatchTV activity): “5646877223

Source: jointSPACE TVs Developers

Before activation, only port was open 49153. After that, port 2323 was open as well. But the app doesn’t work on this TV. This does work however: Philips MyRemote – Android Apps on Google Play
