An easy technique for ellipsis drawing on JavaScript canvas objects

During my recent struggle with the JavaScript canvas object I was looking for a method to draw ellipses. Originally I was trying to use the arcTo() and even got desperate enough to have a quick play around with the bezierCurveTo() and quadraticCurveTo( ) functions before the obvious solution dawned on me.

In the event anybody else wastes their times looking for a way to do this try the following:

var e = document.createElement("canvas");
document.body.appendChild(e);

Installing the link layer topology discovery (LLTD) protocol responder on Debian Linux

This post on how to install the LLTD is largely ripped off from http://www.howtoforge.com/installing-the-lltd-protocol-responder-for-linux-on-debian-lenny and made a bit more direct for those that just want to make it work and not pay attention to what you're doing! Like me!

So let's dive right in.

mkdir lltd
cd lltd
wget http://download.microsoft.com/download/b/8/e/b8eee444-f8d5-4b8b-aa3d-2f19bf19ac72/Rally-LLTD-PortingKit.exe
unzip Rally-LLTD-PortingKit.exe
sudo apt-get install linux-headers-`uname -r` build-essential

Microsofts open source push

Microsoft is now a major sponsor of the Apache Software Foundation and is putting its protocols and formats into a royalty-free license, all part of a larger open-source push.

Big things are happening with Microsoft lately. As an Open Source developer by nature I can say that I was a little shocked when they first opened their Microsoft Office document format specifications (which I was sad enough to read!). There are various news stories where Microsoft is becoming more open. I like it. I like it a lot.

As to why they are doing it, the only reason I can see is that they are taking a beating in the the computer industry with competitors like Apple, IBM, Mozilla and Google all peaking at their profits. Not to mention the European computer laws on monopolistic behaviour. They need to form alliances and change market opinion about them if they want to remain unchallenged.

The curious condition called "Life"

Yes, we are all still alive! The slow release of new content has been a side effect of "life". We apoligise. We hope to correct this situation called "Life" as soon as possible and return to our regular nerding.

For myself, I have been very busy socially and professionally for the past month. Still got a bit to go before it's over. I am getting a new laptop soon (later today in fact. My parents are coming to stay and they are bringing a new one for me! I'm looking forward to seeing it more then I am them!) so perhaps I'll have the processing power to actually open up OpenOffice and get some article writing done!

As for everybody else, they have either been caught up in "Life" either socially or professionally. Ben has a job working for a video editing company (or something like that). Nemmy I think got a girlfriend (the traitor!). Cyrus is still full of excuses why he hasn't posted his mythical article yet. AtnNn seems busy with University. Michael has gone AWOL again and Neil. Who knows?

Relaunch of some nullnetwork tools

As part of my directory clean up I have reinstalled some of my old subdomains, but for the neverfear.org project!

wol.neverfear.org is a web based Wake-on-LAN client. Great for using your cell phone to wake up your computer. After a busy day at the office to save time, or perhaps you are being a Girl back and you have your computer set up to play mood music on wake ;-) (not so unrealistic, I've done these sorts of things!). Whatever you need it for, here it is.

paste.nulldigital.net is current under spam bot attack so I've disabled the paste list function, however still a nice little tool, mostly because when anything is pasted it signals our IRC bot to let people know!

Super simple (common) php hax for dummies.

What follows is a repost of my first article on nulldigital.net, on the 10th of May 2006. A long time ago, when I was all innocent! Good times. The original article as been modified slightly as I sounded like such a git back then. I know it's slightly simple for this site but since nulldigital.net is closing I want to repost the articles from there to neverfear.org. So lets get started..

Global scientology protests begin

There is a lot of news around about Anonymous lately. I can't say I've ever paid them much attention. I thought what they were doing was mildly amusing. I never expected it would actually have a real world impact.

I fear I underestimated them. Today, a Scientology protest, organised and credited to Anonymous has made the front page news of NEWS.com.au with this story titled Scientology protests start across Australia, which documents protests in Perth, Melbourne, Sydney and Adelaide.

How to easily stream ascii videos

This article is a brief tutorial in how to make your own ascii internet TV station. I say brief, its pretty simple - that's why its brief.

The inspiration for such an article comes from having a telnet link posted in a channel to a server which was showing a World Cup game live via ascii and sockets. I pasted this around to a couple other people and some folk didn't understand how it worked, so I wanted to share some knowledge.

Incase some of you aren't following me, the link I was shown was

Using ICMP tunneling to steal Internet

Introduction

The scenario is you are without Internet connectivity anywhere. You have found either an open wireless access pointed or perhaps you're staying in a hotel which permits rented Internet via services like

Spectrum Interactive (previously known as UKExplorer). You make the connection, whether its physically connecting the Ethernet cables, or instructing you're wireless adapter to lock onto the radio signal. You are prompted with some sort of authorisation page when you open a browser. You don't have access to it, so what do you do?
