Silicon Sparrow is where it is Happening

Wed, 08 Feb 2012 05:16:01 +0000

Yeah, this blog is kind of neglected these days. I generally post on so why not head over there and have a look at my newer posts or you can follow me on Twitter.

Dishwasher repair success

Thu, 14 Apr 2011 10:46:45 +0000

My LG dishwasher had an odd problem. Some days it would wash everything in the top basket but not items in the bottom basket, other days it would wash stuff in the bottom basket but not the top. The dishwasher is still under warranty but LG customer service are more interested in annoying their customers […]

2011 The Year Stuff Breaks

Mon, 28 Mar 2011 23:39:59 +0000

One thing I’ve noticed about 2011 so far is that I seem to have a higher than normal amount of breakdowns with all my machines. We’re not even a quarter of the way through the year and already I’ve easily spent more than $2000 and more hours than I’d like to think, repairing or replacing […]

Concatenating SRT subtitles

Sun, 23 Jan 2011 21:25:11 +0000

Ever get a movie which is split into two parts? I usually use AviDemux to join the parts back together but what if the movie has srt subtitles – Here’s how to join two srt files together and adjust the timestamps using srttool in Ubuntu: First install the tool: sudo apt-get install subtitleripper Then use […]

Car Repair Win #2

Wed, 12 Jan 2011 02:42:11 +0000

Of course as soon as you fix one thing, another thing breaks. I went to open the tailgate on my Subaru today and couldn’t. So I climbed in through the back seat and attempted to open it from the inside. Trying to force the catch with a screwdriver didn’t work so before I broke anything […]

Car Repair Win

Sat, 08 Jan 2011 09:15:07 +0000

I have this Subaru Outback, it needs repairing a lot and it costs me a fortune. So I’ve started attempting some repairs myself. I’m not naturally mechanical so I only attempt jobs where I think I might have a chance – that is, jobs which are light on the grease and torque-wrenches and do not […]

Junior Hardware Repair

Sat, 01 Jan 2011 22:12:27 +0000

I had this faulty video card so I got the experts onto it… Looks like a good job. It’s sure to work better than before!

This site got a mention on Reddit for a day. Can you guess which day?

Fear tactics

Thu, 24 Jun 2010 01:16:46 +0000

Sometimes I think the world has gone mad. Does this label imply that all other drink bottles contain leaded plastic?! What will we have next – Cyanide-free Weet Bix?

How much would you pay for a worn out tyre?

Tue, 04 May 2010 08:00:57 +0000

Yep, for those people who want a tyre swing for their kiddies but are unable to tie a piece of rope onto an old car tyre, you can now buy them pre-assembled at Bunnings!

OMG, I’ve been hacked!

Tue, 09 Feb 2010 23:21:55 +0000

Apologies to anyone who has logged into this blog in the last few days only to find a link-farming spam page. Seems that someone has managed to pull off a script injection on this site. I’ve removed the offending code but I still have no idea how they managed it. I’m investigating…

Halloween comes to Sydney

Sat, 07 Nov 2009 10:05:10 +0000

Halloween usually isn’t very popular here in Australia but this year it sure was! Residents of Matthews St, Davidson were inundated by hundreds of kids demanding sugar. My own kids were among the throng, I was surprised how many people were there.

Textapox is catching

Sun, 20 Sep 2009 23:53:27 +0000

Look out for this new disease sweeping the children of the world. Symptoms include coloured spots on exposed areas of skin and uncontrollable giggling.

Python function is not callable

Wed, 16 Sep 2009 10:39:12 +0000

Here’s a Python gotcha that got me. Here is my function to print out a range of sinusoidal values: import math def cycle(centre, range): theta = 4.71 speed = 0.1 for i in range(0,80): theta = theta + speed value = centre + (range * math.sin(theta)) print value I got the following error which confused […]

Girls have more stuff

Wed, 09 Sep 2009 11:11:09 +0000

I just want to say that women just have more stuff. Here is the state of our dressing table right now, you can just see my stuff in the corner there if you look closely but look at my wife’s stuff – handbags and hats and jewellery oh my!

More Spreadsheet Tomfoolery

Thu, 03 Sep 2009 04:10:36 +0000

I’m still messing around with my bookkeeping. Here is another nifty formula for OpenOffice Calc. I have a list of revenue and the dates that revenue was received like so: Date Amount 10 Jul 2009 $1,080.00 18 Jul 2009 $144.45 30 Jul 2009 $2,248.40 2 Aug 2009 $1,000.00 5 Aug 2009 $522.30 I want to […]


Sun, 16 Aug 2009 12:18:39 +0000

I realise I’ve been a bit dark lately with my blog with very minimal posting over the last few months. A lot of things have been changing around here. My wife and I have swapped roles. That’s right, I’m the housewife now and she has a full-time job. I’m still doing some contract work here […]

Parallel port control in Python

Mon, 10 Aug 2009 01:11:13 +0000

Controlling the parallel port has always been a pain in Windows 2000, XP and later. In DOS or older versions of Windows you could just write a byte directly to port 0×378 and that was it. Now you can get the same level of simplicity using inpout32.dll and Python. Go here to download the DLL […]

Australian Income Tax Spreadsheet Formula

Wed, 29 Jul 2009 12:47:36 +0000

Just a quick note for my future reference. I’m setting up my budget spreadsheet for the new financial year and I have converted the Australian 2010 income tax rates into a spreadsheet formula. I use OpenOffice, it should work fine in Excel too. =if(A1<=6000;0;if(a1<=35000;.15*(a1-6000);if(a1<=80000;4350+(.3*(a1-35000));if(a1<=180000;17850+(.38*(a1-80000));55850+(.45*(a1-180000))))))
