Ok.. so I promised that I’d give a few photos once I’d fully moved in to my new place – so here it is..
This first photo shows the place during the day..
Note the cool pink bouncy sitting ball above – very Googley – Jazz, my hound, loved it – happy to chase it around all day.
Alas, Jazz’s days of fun with the ball are now over.
Jazz doesn’t realise how sharp her fangs are, and she is currently lying on the remains of the pink ball mourning – this photo I took just now 😀
If you’re from Google, and you have a tough, more dog friendly ball – I’d suggest you be totally Googley and send Jazz a new bouncy ball – the poor chook is very depressed, as you can see – Prozac anyone?
This photo shows my house after dark.. yes, it’s still small, regardless of the time of day 🙂 That is a photo of my girlfriend, Claudia (Schiffer), on the wall, by the way 😀
And.. of course, the computer desk.. here we have a lenovo T60 (lovely computer, donated by lenovo as support for my PhD, thanks Lenovo!) on the left, followed by my new E8200 based overclocked behemoth, and finally my Q6600 based quad core super-data-muncher GIS computer on the right. I wish I had three eyes.
And, naturally, everyone needs to wash – in keeping with the rest of the house, the bathroom is tiny.
Where is the toilet I hear you say – well, it’s actually in a seperate building.
This is very much a batch pad, folks – but after several years living in Asia / PNG it doesn’t worry me a bit – I actually like it – don’t ask me why – I just do.
Gets a bit chilly up here – the pot belly stove keeps me warm, adds ambience and heats my water.
And of course, the most important thing when you’ve locked yourself away to study and write a PhD – company.
Luckily Jazz, the alsation / kelpie cross, also serves as the garbage disposal unit;
Between Jazz and the pot-belly stove I don’t tend to generate much trash other than plastics – which is a good thing, as we don’t have a garbage collection up here – even though we’re only 15kms out of the centre of town.
And, naturally, if you’re wondering why I’ve moved out of town, this photo should explain it –
Apart from the fact that I get to play the music I love (alot of Paul Simon at the moment, I admit – right at the mo I’m hearing ‘spirit voices’ – love it) – I jog about 5 miles (round trip) down a big hill every morning and back – this is my reward at the end of the walk – I live right on the edge of a national park (forest) – see (or smell) koalas and kangaroos almost every morning, and end up HERE –
I’ve had a few folks up here tonight for house-warming – been very fun – actually, 3 Californians – Dave, my chef mate (naturalised Australian now) and two of his nephews from Mountain View.
Cheers and hope you are all well.
UPDATE:- Four hours later – not cuddling with the carcass anymore, but still within a few feet of ‘the-deed’ just-in-case 🙂 – still desperately depressed, but beginning to figure that all these photos and pats must mean biccys are coming soon, I figure.
UPDATE 2 :- after 24 hours of witnessing a dog in deep depression, I caved and bought Jazz a new ball. She’s happy again now 🙂

I notice a few of my friends turning up on my mybloglog sidebar.. so.. just a shout out to a few.. John – fantastic to see your blog getting the traffic it deserves lately for some inspired commentary on what peeves us about the inadequacies of Google Webmaster feedback. Shambhavi, I’d love to hear how you’ve settled in since your big move.. possibly you’re visiting in the vain hope that I’ve updated my blog recently – alas no, I haven’t.. UNTIL NOW…
But.. in all fairness I have been genuinely really busy. I’ve completed the long and drawn out process of moving into my new house… And, as the title of this post would suggest, I’ve actually managed to get broadband internet working here – which is very satisfying indeed.
Once I’ve converted my new place from the current maze of boxes to something a bit more worthy of a few photographs, I will do a post about it.
It’s certainly a unique place and I think some of my non-Australian readers would be fascinated – it’s definitely a very ‘Aussie’ pad – we’ve got Kookaburras, Kangaroos, Wombats.. very relaxing.. it’s such an Aussie house that the first thing I bought was a BBQ – and I haven’t cooked inside even once in the four weeks since I started moving in (Sorry folks from the US, but we’ve had absolutely brilliant weather here – warm, tropical).
I’ve been travelling alot recently, but by far the most ‘important’ thing I have been doing is consulting to a company in the North of my state – developing yield maps that help sugarcane growers improve their productivity whilst simultaneously reducing their costs – the fabled ‘win-win’ solution. It’s something very interesting, and I’d like to blog about it here.. But… I need your help.
Does anybody know of any free or open source software that allows you to record your screen in real time as a video? I basically want to do an online ‘tutorial’ about my new ‘yield mapping’ sofware – I’ll be putting it on my business site (www.jaisaben.com) of course.
Your help would be appreciated!
Oh – one additional subscript – those of you that know me well will know that there has been a stressful sidetrack regarding a new lingerie product over the last little while – I spoke about the stress of that particular venture quite briefly on the website of a friend a couple of months back.
I’m glad to say that this is now completely over and done with. We won the case – something I’d never like to go through ever again, but it’s given me some new and interesting insights into the challenges that entrepreneurial businesses and webmasters face – and those kind of insights are priceless.
I now feel quite qualified to advise folks about the legal side of webmastering – how to be ‘savvy’ about these issues and avoid destroying a great business with endless legal battles 🙂 It’s an important lesson – your time should be spent building a business. Time in court is wasted time folks!
Cheers and all the best,

So.. I’m currently moving house – It’s been on the cards for a while but I put it off pending a reply from a company I had been hoping to snare my ‘dream job’ with. The reply came, and it looks like I’ll be continuing my current status as a self-employed consultant/ PhD student for a while yet (dawgammit) , so it makes sense to make the move now.
I’ve found a fantastic place about 25kms out of Brisbane, at a spot called Mount Nebo (quite near to where my parents live, actually). The rent is good, the view is FANTASTIC and it’s a rural area, so I’ll be able to get back to my roots and have a few chooks etc 🙂
One big problem – if you can believe it – here in Australia, only 25kms out of a major city I cannot get broadband internet. To understand why this is, consider that the telecommunications utility (Telstra, often perhaps aptly renamed Hellstra) in this country was until recently Government owned, and is now a publicly owned company – so now the mighty dollar rules the roost.
It strikes me as a bit odd that the government would privatise a company that provides a service every bit as important as other utilities like water, electricity etc, without imposing conditions – like, for instance, the need to provide that service to folks where the population density might not quite make it a rapid return on investment – that is, after all, the reason that we have government owned utilities in the first place.
Actually, these days broadband internet is probably a more important utility than water and electricity – if you’ve got no water, you can always collect it from your roof. If you’ve got no electricity, you can always probably pay for solar panels. If you’ve got no broadband – well, sorry mate – you’ve just got no broadband. Hard luck.
This has resulted in the issue becoming a hot political potato. In fact, one of the major election promises of the incoming Rudd Labor government was that they would ensure that the entire population of Australia would have 8Mbp/s internet connections within several years if they were elected.
To this, the current American CEO of Telstra, Sol Trujillo, rejected the Rudd Labor Government’s idea of Telstra and its competitors all forming a jointly owned ‘new’ broadband network (probably FTTN – fibre to the node) as being some form of ‘kumbaya, holding hands theory – we are only going to participate in things we own and control’.
I must admit I can see his logic – CEO’s are paid the big bucks to maximise shareholder value. Opening up your monopoly owned exchanges and infrastructure to competitors for ‘the common good’ doesn’t cut it in this modern world of capitalism.
On the other hand, Telstra also blissfully enjoys their monopoly.. they argue I can get broadband – their wireless (3G) offering – Next-G. Yep, it’s fantastic – a whopping top speed in the area of 512Kbps, and only the low low price of $US150 per month for a maximum of 3GB download capacity.
I can use 3GB in my sleep – just 10kms down the road I can get 50GB a month for $50 at 5Mbps… so.. broadband at 100 times the market rate and 10% of the market speed is really only for those that have too much money or too few brain cells.. so. no broadband for me – I’ll have to buy a carrier pidgeon instead.
Alternatively.. well I am a comms engineer so.. I have the technology. I might just see if I can’t find someone with ADSL broadband in the valley below and offer to pay their monthly fees if I can rig up a yagi from their property and longshot the internet over an 802.11g/n link. It might be not strictly legal, but avoiding not-strictly-legal conduct is probably the reason that they never privatised the police force as well…

Ok – so, if you read my last post about GIS systems and Sugarcane Yield Monitors you would be well aware that I’ve been labouring with a very processor intensive task called ‘Inverse Distance Weighted Yield Projections’. With over 2 million data points, the process takes many days… SO… in the interest of speeding it up, I recently decided to buy and overclock one of the new generation ‘Wolfdale’ Intel 45nm Core 2 Duo Processors – the E8200, which is the little brother to the new e8400 and e8500 series.
Firstly, the E8200 processor itself uses the same socket (775) as Intel has been using for quite some time now, but as I’ve been using AMD 64 processors up until now (socket 939), I needed to get a new motherboard as well – I chose the Gigabyte P35C-DS3R motherbard.
Meh – what the heck – if you’re going to go all out, why not get the works – so I topped off my purchase with some Kingston HyperX PC8500 DDR2 RAM as well – which is rated to 1066MhZ.
Add to that a nice little RAID 0 array of 2*500Gb 7.2K rpm hard drives for my data, and 1 10K RPM 160Gb WD Raptor, and you’re starting to shape up as a very speedy system.
Recommended Overclocking Settings for the E8200
Ok – so, the E8200 is rated at 2.66 GHz out of the box. With a little trial and error, I’ve been able to get it stable at a pretty decent 3.92GHz with the stock standard cooler. Here are the settings I used –
- Ram Latency Settings – 5-5-5-10
- RAM:FSB Ratio 1:1 (so effectively the Ram is matched to the CPU speed, running at around 490MHz – well, actually, 980 because it’s DDR – double data rate)
- CPU Core voltage – 1.25 volts (this one was a suprise – many folks suggest you need to go as high as 1.5 – I didn’t)
- RAM Voltage – 2.2V
- CPU Clock 490MHz at the default multiplier of 8.
The system (on account of the low voltages) actually runs very cool – around 42 degrees Celsius (107 F) at idle, with a max temp of 62 degrees C (141 F) running Prime95, which is a CPU testing tool (amongst other things) – and that’s just using a stock CPU cooler with Arctic 5 heatsink compound.
Cool, in my mind, is good. If a processor runs cool, it’s usually a good sign that it is energy efficient – and it definitely means that less energy has to be spent keeping it cool which means lower electricity bills and a smaller environmental footprint – a good outcome all round.
So… contrary to the bad press I have heard elsewhere about the E8200 being not so overclockable, I’m absolutely stoked with these figures – but rumor has it that the E8400 and E8500 are getting prodigious numbers in the mid 4Ghz range, so they may be worthy of the additional investment, although the E8500 is a little overpriced for only an incremental increase.
For those of you interested – my particular CPU is the number 6 stepping – here’s a picture of the processor’s SuperPi numbers (just over 12 secs) –
Some Additional E8200 Overclocking Tips
- To get very high CPU speeds like those noted above – YOU WILL NEED FAST RAM that can quite happily sit at ~ 960Mhz or above. A high quality DDR2 800Mhz stick MIGHT cut it, but I’d recommend going for a min of 1066MhZ RAM (PC8500), otherwise you’re going to find your overclock will be constrained to around 3.3Ghz.
- A New RAM technology is currently emerging called DDR3 – It offers speeds in excess of 1066MHz, but it is horrendously expensive – consider getting a motherboard (like the gigabyte Gigabyte P35C-DS3R I chose) that can handle BOTH DDR2 and DDR3 memory – socket 775 is going to be around for a while, and you might want to use DDR3 in the future.
- Don’t go overboard with the CPU voltage – some people are recommending as high as 1.5V, but I’ve found that past 1.3V you are mostly generating exponentially more heat for very little additional clock speed – it’s not worth it unless you’re nuts and like spending heaps of money on expensive cooling gear.
How did you go? Did you achieve the same speeds? Are you doing better with an E8400 or E8500? How much better? Got any questions? I’m really keen to hear from you – leave a comment below!
All the best –

Hi Everyone – long time no post, I realise.
Ok – so a bit of an update – I’ve spent the last little while learning a new language (VB.NET). It’s been a nice challenge, as most of my programming to date has been non-object oriented stuff – command line interfaces or totally embedded solutions usually written in ANSI C.
I’ve been up in North Queensland helping a company up there develop yield maps for their Sugar Cane harvesters (actually, I helped design the equipment that sits on the harvesters and does the yield monitoring, as well). The process of taking the raw data off the harvesters and converting it into yield maps is a fairly long and drawn out one. Firstly you need to filter the data (something I had been doing in Excel) to remove erroneous positions and obvious outliers.
Secondly you need to convert the latitudes and longitudes from the yield monitor into eastings and northings (A degree of latitude isn’t the same distance at every position on the earth) so that you can project the data onto the local industry GIS system (the projection used is called the Geodatic Datum of Australia – GDA Zone 55) which was a bit of a mission – I had to convert a long and convuluted mathematical process (about three pages of equations) into a neat little visual basic function.
Thirdly you need to tie the data back to actual weights to obtain a calibration for each machine (had a hybrid Excel / Access database for that job) and fourthly you need to have a way to automagically recalibrate the harvester as the season progresses and the pressures that the yield monitor uses to monitor cane throughput start to change (mostly they go up – wear and tear on the harvester).
I was planning to teach my clients how to do this all manually, but, since I had a hankering to learn a new language and wanted to make life easier for them, I asked a famous Googler what object oriented language he would use. He suggested visual basic, which suited me fine because it turns out that it’s quite similar to C in many ways.
So.. now.. a month later I know a new language and have a great
little humungous larger and more comprehensive than I ever imagined software package.
The package condenses what took me about 7 or 8 days to do using excel spreadsheets etc into an algorithm – essentially distilling it down into a 5 minute batch process. The danger is that it will look TOO easy and my clients won’t appreciate the effort that’s gone into it 😀 – but, meh, the satisfaction of a job well done was worth the extra effort.
Once the yield data has been processed by the software, it then connects into a GIS system which converts the point yields into a smooth surface – a yield map. The one I use alot is called ArcGIS, and it makes life rather easy. Specifically, it uses a function called ‘Inverse Distance Weighted (IDW) Interpolation’ to draw the map. Basically, for every recorded point from the datalogger, it looks at 8-12 other nearby points and uses them to ‘guess’ what the yield may be between the points – and hence comes up with a nice smooth yield map.
That process can take a long time – for a years worth of data for 23 harvesters in Australia the process of calculating the IDW maps took me about 3 days with my Opteron 165 based system – which leads me into my next post – about my new computer (feeling very Geeky here).

I like to write the occasional ‘how-to’ on this site to answer questions I’ve found really difficult or impossible to find an answer for online.
Ok – so… recently the keyless entry remote for my 2003 BA XLS Ute went on the fritz, which caused the ‘panic’ alarm to go off at all hours of the night without warning.
I did actually find that replacing the battery of the remote seemed to cure the problem – but I went to the wreckers and bought a second hand remote as a spare.. so.. here I’m going to tell you two things:-
- How to replace the battery in a Ford remote control (specifically these instructions are for the BA model Ford Falcon, but they should be applicable across the range), and;
- How to program a new remote control (keyless entry fob) for a Ford Falcon.
How to replace the battery in a 2003 model BA Ford Falcon Keyless Entry Remote
This one is really easy – just pop open the remote using a 5c piece and replace the battery with a CR2032 battery available at your local supermarket for around $5.
The batteries need to be replaced every couple of years.
How to Program a New Remote Control for a Ford BA Falcon
This one is a closely guarded little secret – Ford won’t tell you – but I happened to get my hands on a full workshop manual for the BA series.
After skulking around the ill-gotten workshop manual I managed to find the ‘secret’ technique hidden right at the back (along with a few other ‘gems’). Ok – here’s the procedure to program the new remote –
- Obtain a remote (can be a second hand one – they can all be reprogrammed, or you can buy a new one for about $90 from Ford).
- Close the doors.
- Turn the ignition key to the accesories position.
- Within 5 seconds of turning the key, hit the rear demister button (center console) three times in succession.
- The door locks will cycle once to indicate the special mode has been entered.
- Press any button on the remote you wish to program.
- The doors will cycle to indicate a new remote has been programmed.
- Continue steps 6 and 7 for all remotes (including existing ones) you intend to use on the vehicle.
- When you’ve programmed all the remotes, turn the ignition key off. The doors should cycle again to indicate the programming session has been completed.
For the techies amongst you – It’s interesting to note that you are not actually programming the remote per se, but rather you are programming the car. The late model Ford’s all have a BEM (Body Electronics Module) which is basically a fully fledged computer. When you press the remote, it ‘squawks’ a unique code to the car BEM. If the BEM is in the special programming mode, it then enters this code into memory as an authorised fob.
Something else I found a bit interesting – there is apparently an RFID (radio frequency ID) chip in the key of these new cars. Even if a key happens to fit your car, unless it’s been programmed as an ‘authorised key’ using a similar technique you won’t be able to start the vehicle.
How to get a Workshop Manual for the Ford BA Falcon
The workshop manual is about 2100 pages long – if you’d like a copy click ‘buy me a beer’ to the right of this post, donate $10 to cover the bandwidth and I’ll send you a link – it’s about 120MB.
If this advice didn’t help you – please drop by when you find the solution for your particular vehicle and help others by letting us know (using the comments below) what it was 🙂
Cheers and all the best,

Following on from my post about the incredible progress of computer storage density over the last twenty years, I remembered hearing a ‘popular science’ broadcaster here in Australia equating the gamete transfer during sexual reproduction to data transfer.
I like ‘weird science’ so I thought I’d go back and try and ‘reproduce’ his findings (pun entirely intended) – so – in this post I’m going to explain in ‘digital terms’ (eg megabytes, gigabytes):-
- The number of megabytes of ‘data’ exchanged during human reproduction.
- The amount of data which the human brain can store (hypothetical).
- The amount of data stored in all the cells in the human body.
This post involves some low-level discussion of sexual reproduction. So, if you’re prudish or get offended by this kind of thing, I apologise in advance and please turn away now 🙂
The amount of ‘storage’ in the human brain
We can do similar calculations with the human brain – although these are much less definite – we’re much less certain about how the brain works than we are about how sexual reproduction works.
The average brain has around 100 billion brain cells (neurons) – that’s 100,000,000,000 brain cells (although this is a ‘guesstimate’ based upon other factors).
Each neuron is functionally connected to around 1000 neurons (again, a guesstimate). If we assume that neurons have either an ‘on’ or ‘off’ state (digital logic – although, not unsuprisingly, we have reason to believe that brain storage uses analogue voltage ‘levels’ rather than digital logic for storage) we can then assume that each neuron can ‘read or write’ 1000 neurons – essentially 1000 bits or 0.122 kilobytes of data.
Assuming that this ‘data’ ripples through the brain in a steady-state manner, we can assume that the average amount of ‘storage capacity’ is hence 100,000,000,000 by 0.122 kilobytes, or 122 million (122,000,000) kilobytes. If we convert that figure to gigabytes, we arrive at the sum of 116.34 Gigabytes of data in digital terms.
Obviously there is a massive fudge factor here – the calculations make alot of very ‘broad’ assumptions – it’s really just a ‘fun’ measure of what our brain capacity would be if it was a digital system.
How many Megabytes in the Human Body
This one’s just too complex for me to consider this early in the morning – but lets have a go (drawing on my limited recollection of genetic biology here).
I’d guess to work it out you’d have to define each ‘base pair’ as a bit of information.
In human DNA there are two common base pairs which consist of the ‘nucleotides’ adenine, thymine, guanine or cytosine. Generally speaking only adenine and thymine pair with each other, as do guanine and cytosine – so the typical DNA base pair can be AT or CG – one of two states – a bit.
The human genome is estimated to contain some 3 billion base pairs – so (again, simplifying) 3 billion bits = 0.35 gigabytes – so each cell in our body encodes roughly a third of a gigabytes of information – that’s a pretty high information density, especially considering that the double helix DNA in our cells is a minute proportion of the cell as a whole (and that the process of cell reproduction produces RNA strands which may be present in a cell as well).
Estimates for the number of cells in the human body range between 10 trillion and 100 trillion (see Sears CL. 2005. A dynamic partnership: Celebrating our gut flora. Anaerobe, Volume 11, Issue 5, October 2005, Pages 247-251).
The generally accepted figure is 100 trillion cells – so, given each cell contains 0.35 GB of data, the (very) approximate amount of data held in human cells is 35 trillion gigabytes, or 34,179,687,500 terabytes of data, or, expressed in megabytes 3.58400 × 1016 megabytes!!
If you add in the information encoded in RNA and the base pairs in the bacteria which live in our body (another 1000 trillion cells) then we’re talking about a hell of alot of data.
The human race would make a truly excellent data center if Google ever runs out of storage space or we get invaded by aliens with a need to store lots of information 😀
The number of Megabytes ‘exchanged’ during human reproduction
Each sperm cell in a human male is heterogametic, meaning it contains only one of two sex chromosomes (x or y) – incidentally, the female egg is homogametic – meaning that it only has an x chromosome.
This means the male ‘determines’ the sex of the child, which makes a mockery of Henry the 8th’s annulment of his marriage with Catherine of Aragon on account of the fact that she was ‘incapable of providing a male heir’.
Basically, sperm cells are like bits – they can (in most cases) be only one of two states – x or y, or in digital form, 0 or 1. So, it’s possible to express an ejaculate in megabytes (!?!) – Let’s try.
The average human ejaculate contains around 180 million sperm. So, that’s 180,000,000 bits. If we use google to convert 180 million bits to megabytes, we find that approximately 21.45 megabytes of ‘data’ is transferred during each act of human sexual reproduction in the form of gametes.
Whether this ‘information transfer’ results in anything constructive is up to individual circumstance, but it does raise a number of interesting questions (I’m putting my communications enginner / silly hat on again):-
- Given that this is ‘bursty’ traffic, what is the peak data transmission rate (in megabits per second)?
- How does this compare to optical fibre (assuming the subject doesn’t suffer from ‘dark fibre’ problems 😀 )?
Have you got any other ‘fun science’ questions you’d like answered? Any comments? You can leve your comments below.

Ethanol as a replacement for petroleum
Back in my undergrad degree, I did some research into the viability of using resources from Australia’s large sugar cane industry as a feedstock for ethanol production.
My research was completed about 10 years ago. I found that for Australia to fulfill its own oil demands with Sugar Cane based ethanol it would need to have the entire arable land mass of Australia under cane and that the cost of production would be around 60c per litre, or about US 2.26 per Gallon.
The Australian retail price of petrol back then was around the 60c mark. It was clearly an impractical and uneconomic proposition.
Replacing Oil with Ethanol?
I went on to spend some time with the Sugar Industry and I found along the way that really my calculations were entirely flawed.
Firstly, I’d assumed that the feedstock for my theoretical ethanol production would be something called Molasses. Molasses is relatively cheap and abundant by-product of sugar production and is often used to produce rum. It contains perhaps 5% of the available sugar produced from the processing of Sugar Cane – with the remainder generally converted into relatively high value crystal sugar (the type we use in our coffee).
Two things have changed since then – the world price of sugar has precipitously declined and the world price of oil has sky-rocketed – so the economics have changed. I thought I’d take this opportunity to cast a backwards glance and go over my figures once again.
Brazil can switch between ethanol and sugar production almost instantaneously!
Brazil (the largest producer of sugar cane in the world) has over the last 10 years or so built the capability to easily tailor their production to either crystal sugar or ethanol – basically if the oil price is high, Brazil starts producing ethanol.
Due to the enormous size of the Brazillian industry the resultant shortfall in crystal sugar tends to drive up the world sugar price – so much so that over the last 5 years or so we’ve started to see the world sugar price (WSP) follow the peaks and troughs of the oil price.
Already, without even realising it, Sugar has become an agro-industrial energy crop. The same thing has happened with corn as well – in recent years the price of maize has doubled in much the same way as the price of oil has.
This is a very different playing field to that I investigated 10 years ago – ethanol production from sugarcane is now starting to become an economic proposition of some merit.
A friend of mine in the south of India has secured the rights to build an ethanol factory in a state called Kerala, so I’ve been speaking to some experts here in Australia on his behalf about the new state-of-the-art in ethanol production.
Kerala has a rather large Coconut industry, and one of the interesting possibilities we are looking at is cellulosic ethanol, which has recently been featured in this great article from wired magazine.
This is still a technology in its infancy, but things are looking very promising. Cellulose is the stuff that makes plants stand up – it’s tough, it contains a great deal of Carbon and it’s not easy to break down.
For all our evolutionary complexity, we as humans haven’t yet developed the ability to utilise cellulose as an energy source in our diet, although that’s not the case for other organisms.
Ruminants like cows, goats and camels are capable of supporting vast populations of bacteria in their gut which digest the cellulose and produce by-products called (again, simplifying) short chain fatty acids which can then be digested by the animal as an energy source.
Termites go a step further – their guts apparently produce these enzymes in-situ without the need for a symbiotic colony of gut bacteria.
In recent years there has been a veritable explosion in the number of companies (and governments) investing in this particular technology.
What are the expected yields of alcohol per tonne of Cellulose?
It’s very hard to find definitive numbers here though that allow us to start looking at the potential economics of using cellulose from plants as a ethanol feedstock.
One article about the economics of cellulosic ethanol production states that the theoretical yield of ethanol per tonne of biomass is 114 gallons (431 litres), but in practice the real (achieved) yield is closer to 70 gallons (264 litres). Unfortunately that particular article doesn’t express ethanol production as percent dry biomass (aka dry matter) so it’s hard to compare it with other studies.
Another article I found goes into a bit more detail and compares potential cellulosic ethanol production between four feedstocks – corn stover (another name for corn stalks), alfalfa stems (lucerne), sugarcane bagasse (the dry fibre left over after sugar extraction, usually burnt as a waste material) and Oak Wood. This particular study expresses Alcohol production as litres of ethanol per tonne of dry matter – a much better measure.
|Conversion efficiency (%)
These figures tend to correlate well with those given in the first reference – that expected production of ethanol per tonne dry biomass is going to be somewhere in the order of 220-280 litres of ethanol. It also correlates fairly well with a ‘tool’ provided by the US Department of energy which allows you to calculate the theoretical yield of cellulosic ethanol based upon the composition of a biomass feedstock.
So.. down to some economics..
Let’s take a reference (underestimate) of dry matter % sugarcane biomass as ~14%. So, for every 1000kg of sugarcane, we’ll assume we’re left with 140kg of dry cellulosic materials after extraction of the sugar. Assuming 260 litres per tonne biomass, that means that we’re going to expect to produce around 36.4 litres of cellulosic ethanol per tonne of harvested sugarcane.
Now the important part – Sugarcane uses what’s called C4 photosynthesis – meaning it’s extremely effective at producing biomass from sunlight – biomass yields are very high and the plant is extremely fast growing. A typical yield of sugarcane per hectare in Australia would be ~ 70 to 150 tonnes cane per hectare per annum. We’ll take the midpoint – 100 tonnes.
This means that from cellulosic sources, we’d be expecting to produce around 3640 litres (961 gallons) per hectare of cane from a material that is otherwise considered a waste product.
What about if we used the sugar too?
Now lets look at the sugar content.
Fleay et al (2006) states that (one tonne of) “sugar yields 0.385 tonnes of anhydrous ethanol” and the specific gravity of ethanol is somewhere between 79% and 81% that of water, meaning we can expect the yield of anhydrous alcohol per tonne of sugar to be (1/.8*385)=481 litres.
In general the CCS of cane (amount of sugar in a tonne of cane expressed as percent biomass) is somewhere between 10 and 14% – and that doesn’t include the sugars available in molasses. Let’s assume that we just macerate the cane, extract the juice and ferment that (a much less energy intensive process than extracting the sugar) – we’ll make a relatively broad assumption that we’ll have around 140kg of sugars available per tonne of cane, which, at our theoretical yield of 100 tonnes per hectare equates to around 14,000 kg sugar per hectare available for fermentation and conversion to ethanol. At 481 litres per tonne of sugar, we’ll be left with around 6735 litres of ethanol per hectare.
So.. we’re left with the following figures.. from a ‘typical’ cane field with 14% fibre, 14% available sugar and 100 tonnes per hectare..
Yield of Cellulosic Anhydrous Ethanol per hectare – 3640 litres
Yield of Fermented Anhydrous Ethanol per hectare – 6735 litres
Total yield of Anhydrous Ethanol per hectare – 10,375 litres
Could Ethanol totally replace our petroleum usage?
Would this be enough to satisfy Australia’s Oil needs?
Let’s assume an annual cane yield of 40 million tonnes, or roughly 400,000 hectares under cultivation – this equates to around 4 150 000 000 litres, or 4.15 billion litres of ethanol per annum (assuming one crop cycle per year)
The energy density of ethanol is only around 70% of that of petroleum so this would equate to around 2 905 000 000 litres (2905 megalitres) of petroleum (although ethanol does have a higher octane rating, which means it burns more efficiently, so this is probably a slight underestimate). Current petroleum consumption in Australia is around 20,000 megalitres per annum, leaving a shortfall of over 17,000 megalitres per annum.
WOW! If Australia was to convert our entire sugar industry to the production of ethanol, we’d only be able to satisfy around 14% of our demand for automobile fuel (not including diesel consumption which is another 4000 megalitres). Keep in mind Australia has only 20 million people.
The scale is enormous – in QLD you can basically drive for 2000 uninterrupted kilometres and all you’ll see growing is sugarcane.
If we wanted to gross up our cane production to satisfy our demand for foreign oil (for automotive use only), we’d need to have around 2,857,000 hectares under sugar cane – the entire cropable landmass of Queensland (approx 20% of Australia’s land mass) is just below that figure. Forget about eating – we’d need to crop our whole state just to satisfy the thirst of the nation’s automobiles. That’s quite amazing and I feel the figures for a country with a much higher population density like the US would be even more compelling – these are interesting figures.
This reinforces a few things to me:-
- The massive scale of our oil consumption is easier to comprehend when it is expressed as biomass equivalent production (the amount of oil beneath the earth was phenomenal)..
- That burning that finite resource to fuel inefficient vehicles rather than using it for higher value industrial purposes for which no other economic feedstock exists (plastics, medicines etc) is perhaps not the best long term use of an amazing natural resource.
- That folks are going to look back at this period of history and wish we had done things a bit differently.
What are your thoughts? Where do you think the future lies? I’d be keen to hear your ideas / opinions.

Brief update – I got a new vehicle today.
I’ve been driving around an ancient vehicle with 300K+ km’s for the last 5 years – and finally I decided it wasn’t really worth spending any more money on.. so today I purchased a new old ute at auction.
For those of you who aren’t from Australia, a ‘ute’ is like a pickup – it’s a uniquely Australian invention that was designed to allow farmers to have a vehicle that they could use during the week on their farm, and still be ‘beautiful’ enough to take the wife or significant other to church on Sunday without causing embarassment.
The fact they only have two seats and a v6 engine is a bit of a problem in this modern world of high fuel prices and environmental conscience though – and on that matter I feel a little guilty. There was a Prius that went for about $5K more, and I did consider it (momentarily).
If it weren’t for the fact that utes were made for dogs and dogs were made for utes and dogs aren’t allowed in ‘family cars’ and I have a dog, I’m sure I wouldn’t have got a ute – but I have horses and dogs and love the country – so i’ll stay with the ute for the moment and ride my bicycle around town to help limit global warming and waist expansion 🙂

In a case of
short term pain for long term gain long term pain for short term gain, everyones favorite search engine has abolished the supplemental index.
But before you go running around your office whooping with delight like I did this morning – STOP. Google hasn’t abolished the supps, they’ve just stopped telling us which pages are in supps.
What’s that mean to the average punter?
Well, it means less questions on the webmaster forums starting with ‘why are my pages all in the supplemental index’, and less time spent by ‘mom and pop’ sites worrying about it.
Possibly a good move.
Me, well, I’m skeptical about the move. The overriding stated aim of Google is to return quality results. I’ve seen plenty of quality pages in the supplemental index – google has stated repeatedly that the biggest reason for a page being in the supps is NOT a perceived lack of quality, but rather a lack of pagerank.
It’s nice to know they are there so that we can make an effort to bring them into the main index where they belong. Google should be adding MORE tools to help genuine webmasters assess how they can improve their index penetration, not less.
It’s a case of ‘need to know’ – Google now no longer reckons we ‘need to know’ which pages their algorithms consider unworthy of a place in the main index. My initial feeling about that move is that it seems a little paternalistic.
Google has eviscerated the ONLY tool that goes any way toward explaining why a page might be performing poorly.
My take? If they are going to stop tagging pages as supplemental they should just abolish the supplemental index altogether – if a page is being crawled but isn’t in the index, well, we know it sucks – so why lump it in with other results? Put differently, why show us pages in a site: search if they’re not going to rank anyway.
At the moment I’m leaning towards thinking this might have been a (short term) backwards step, although it wouldn’t surprise me if we see some new tools in the Google webmaster tools arsenal to help deal with this prob.
ADDENDUM:- Richard Hearne (www.redcardinal.ie) put it best recently on the google webmaster help forums –
“Of course Google would rather we didn’t discuss or even consider this supplemental index. Then again if Google was serious about fixing issues like these they would scrap the supplemental index… or give us back the supplemental tag so that we can try to fix these issues ourselves. “

Well I kept it a big secret from you all because I didn’t want to jinx myself – but I was invited recently to an interview with Google (it was the ‘exciting little company‘ I spoke about a couple months back in a post about an upcoming interview).
The position was to be based at Mountain View, California, and as part of the great Webmaster support team – along with neat and very bright people like Adam Lasnik, Vanessa Fox, Aaron D’Souza and Matt Cutts.
The position was ‘Webmaster Trends Analyst’, something I felt uniquely attracted to – I’ve a strong background in stats (from my undergraduate degree and time running scientific trials with the Sugar industry), have run several ecommerce sites and have a Master’s Degree in Computer and Comms Engineering – as well as being a regular poster on the Google Webmaster Forums – so I love hearing about what other folks are up to.
It was an exciting opportunity – so accordingly I took some valuable time off my PhD to prepare – before hopping on the plane for the 13 hour flight to San Francisco.
It was a great experience, but unfortunately I didn’t get the position.
I was disappointed.
As I wrote to one of my contacts about it:-
“so, either I’ll start looking for work again or I’ll bite my bum, put the pedal to the metal and get back into the PhD.
G was going to be a great fit because working with people like yourself would have been a ‘learning’ experience rather than just a job – I hate the 9-5 ‘office worker’ style culture of uni, but love the learning side.
My main problem when it comes to being hired is that of previous job experience..
I start to look like a jack of all trades but an expert at none.
Imho I thought that would be what would get me the job with G, as I’ve been told it makes me a pretty powerful educator – and a great interface between nutty engineer / scientist types and the general public.”
But let me take a step back here for a moment – I need to emphasise that I found the whole experience incredibly rejuvenating and irregardless of the fact I wasn’t successful, I still feel honoured.
If Google were to turn around today and say they wanted to employ me, I’d say yes in an heartbeat.
Why? Because any company that actually recruits internationally for a position known as ‘Webmaster Trends Analyst’ is a company that has a conscience. I don’t see such a position advertised at Yahoo. I don’t see such a position advertised at MSN… actually, I don’t see such a position advertised ANYWHERE.
When I was going through the interviews, one of the interviewers (and I hope I’m not out of line here) actually spoke about the fact that Google pulls together information from heaps of different resources (blogs, forums etc) on a regular basis and tries to quantitatively (from qualitative signals) assess ‘webmaster sentiment’ – and use it as an early warning system to alert them if things (like an algorithm change for instance) have had any unforseen impact. That made me sit back and go ‘wow’.
I count myself very lucky to have been interviewed by a great company with a social conscience like Google and dearly hope an opportunity pops up soon and I get another crack at it (You can contact me if you know of one).
But enough of that – the whole experience was a complete blast – let me show you a few photos.
This first photo is the centre of the Googleplex – it’s a neat place. I like the fact that I seem to have captured a black crow in mid-flight right below the Google sign 🙂
Took this photo on a toilet break at the ‘plex’ – judging from the pace of the interview I figured that time is a commodity in short supply at the googleplex, but this pic (right above the urinal) really rammed it home “Testing on the Toilet” – an A4 page giving thought provoking code tips to the engineers. 🙂
I got the opportunity to do a fair bit of sight seeing while I was there…
The Golden Gate Bridge (with me in front of it).
You’ll notice in all of these photos that I’m wearing one of two shirts – bloody Qantas sent all my luggage to Helsinki on the way over, so I had only a pair of shorts, a pair of moleskins, the shirt I wore on the plane and one I bought for the interview (this one) for the whole trip – don’t get me started about QANTAS.
Across the Golden gate bridge from San Fran is a beaut spot called ‘Reyes Point’ – here’s a photo looking back towards San Fran from there (with the Golden Gate Bridge in the background).
A pretty flower at Reyes point – I believe the plant is called Pigface – why, I don’t know 🙂
A ‘Hummer Limousine’ – Wow!
Another pretty flower in San Fran (are you a REAL Aussie! That’s so COOL! I want a photo with you!!) – the people were very friendly at “Kell’s Bar” – I love a good Irish Pub, and this one was a beauty – it’s just off Columbus.
The owner (right) and head barman of Kell’s Bar..
They shouted me quite a few Guinness’s – here I think that magical brown ale is starting to have its curative effects 🙂 (I am not too sure whether the spooky red eyes were caused by the camera or the Gazillion pints of Guinness)
The morning after – one of those famous cable trams in San Fran.
My Hotel was right in the centre of SF (Sutter and Powell) – I got it for a nightly rate of like $69 – it was fantastic
Just a pretty picture of one of the brass fire hydrants they have all over the place in San Fran.
Some San Fran street art- this was in Chinatown – San Fran has the best Chinatown I’ve seen in any international city – I felt like I was back in Beijing.
On the way out of San Fran – you can see the city itself and the Bay Bridge top RHS.
I loved San Fran – it was such a vibrant colourful city – I hope to go back there someday soon.
QANTAS strikes again – I had to wait 18 hours for my flight back – by the time I took this photo (the time on my watch is AM by the way) we’d been locked in LA airport with no food or refreshments all night waiting for our plane which was recursively only going to be ‘another twenty minutes’ all night.
Some rather unfortunate baggage handler had managed to run into the wing with the mobile stairs, causing severe damage to the port side aileron.
I felt sorry for the parents with little kids – the time on my watch is AM – roughly 20 hours after the plane was meant to leave.

Anyone that uses Google will know that eBay is a major major client of Google Adsense – you’ll see any number of adsense ads for products sold on eBay almost any time you do a search.
In their first major spat eBay and Google has come to blows over an inevitable conflict of interest – Google has recently launched a payment system (Google Checkout) that competes with the eBay owned ‘Paypal’.
In a case of probably going a bit far, Mountain View based Google decided to rent an entire restauraunt across the road from a major eBay event in Boston to try and ‘educate’ eBay officianados about the benefits of their payment alternative.
After a fair bit of sabre rattling from eBay (and the withdrawal of a large proportion of their advertising contribution), Google has backed down and cancelled the soiree.
Let the games begin!

Hi Folks – for those of you who are Blix Krieg users (this theme) I’m currently applying the finishing touches to a major upgrade.
The upgrade adds sidebar widget compatibility and the ability to use asides.
You can check out the progress at http://beta.utheguru.com
I’ve got the asides working just fine, now working on the sidebar a bit to try and make it ‘widget ready’ without making it ugly – because of the way that Sebastien Schmieg made the original blix sidebar, this is a bit problematic – but not out of reach.
June 8th, 2007
Hi everyone.. I write this from LA airport – presently waiting for (delayed) return flight – 3.30am departure.
Don’t fly qantas… on the way here, plane was delayed 8 hours, then they lost my baggage, and took 6 days to find it 🙂
Now due to a crash with a baggage trolley, flight back is delayed too… also by 8 hours,,,, oh well – what can you do 🙂
I’ll talk to you all soon.. lots photos
The rest of this post is an experiment (trying to pull my page about how to get out of the supplemental index out of the supplemental index – it’s called irony – how to get out of the supplemental index) – there – done – back on the front page – now do your thing, googlebot. Oh – and another one – http://www.naturalflare.com to help out someone on the webmaster forums.

Hi everyone –
Just a really quick note –
I’m heading overseas for a big business meeting in the morning – I’ll be away for a week.
Wish me luck!
May 19th, 2007
As you folks prob mostly know, I’m right under the pump at the moment.
Got about 10 balls in the air and trying to juggle them all at once without dropping any..
What does this mean? Writing – loads of writing.. reams and reams of writing – writing coming out of my ears.
Apart from the fact that I’ve rediscovered that the hardest thing about writing anything is writing the first sentence, I’ve also rediscovered the fact that a little background music can help keep you on task and make the hours slip past more quickly and more productively.
With that said, after a week of qualitative experimentation, my thoughts on ‘working music’ (will probably say more about my horrible taste in music than anything else) :-
- 6am – Start the day with something relaxing – I’ve found chill-out albums (depeche mode, coldplay) great for the first hour, then gradually working up – coldplay is another fave.
- 9am-12pm – up the ante – a bit of vivaldi, something classical – this is the best time for writing anything academic.
- 1pm – dinner – avoid the 2pm sleepiness curse – something faster works for me – I hate to admit it, but I’ve rediscovered Kylie Minogue for this purpose.. Sheer volume of written output increases exponentially relative to the BPM of the music, quality perhaps diminishes in same ratio (caution – if you share your office, use headphones during this phase if you want to avoid being shot) 🙂
- After dinner – this is coding time – I find an eclectic mix of low BPM vocal / instrumental is great here – a bit of Dave Matthews / Paul Simon / James Reyne (he’s an Aussie artist folks) early on, followed by something more soothing around 1am to slow down the mind ready for a refreshing 3 hours sleep is great 😉
- Special bonus tip – a mate and I used to combine socialising with study by holding ‘pub-write’ nights – kind of a ‘carrot-stick’ arrangement whereby we’d take our laptops to the local pub, and reward ourselves with 1 beer for every 3 pages written. The net result was usually an enormous volume of writing done, but inevitably said writing tended to become ‘creative’ after ~ 30 pages.. at least one of our joint 1000 page assignments was sporadically ‘sketchy’ as a result 😉
Other tips – if you find yourself lacking inspiration or slowing down, either change the record or take an hour off to hit the gym, then come back and proof read what you have already written – the break does the mind good, the proof-reading gets it back in the groove…
ALL SUGGESTIONS GREATLY APPRECIATED..
May 8th, 2007
I’ve been tagged – by two people in fact – John Mueller (softplus) and JLH (John Honeck) – By the way, all people tagged in this ongoing meme are detailed here.
Softplus asked me to confirm my real name – and whether I use it on my blog – no specific reason i don’t use it on my blog, John – just find theDuck more catchy 😉
I’ve also been asked why I blog, and what are ten things about me you may not know.. so, here goes..
5 Reasons I like to Blog
1. Only so much can fit into my peanut sized brain. I got annoyed with having to go back and search for something I knew I already knew, but had forgotten, so I figured I’d start writing down what I learnt. UtheGuru became that place, and it just happens to be mostly about search as that’s what I’m fascinated about at the mo.
2. I’ve got a scholarship to do a PhD – it’s all about organising data from an industry (sugar). During my Masters Degree (computer and comms engineering – making gadgets) I made a gadget that could collect and send all sorts of data about what a sugar cane harvester was doing to a central point for processing.
It’s a huge long story, but basically I did really well at that Masters (90% plus – it was largely coursework), the silly buggers thought I must have been a bit bright (since my undergrad was science and I’d just blitzed an engineering degree) and offered me a PhD. At the time I accepted because we had some great industry partners.
The PhD was about how to organise the data in such a way that we could combine it with data from the sugar mills and start paying the harvesters in a way that better rewarded the quality of their job – ie, taking quantitative measurements from a disparate range of largely unrelated / competitive sources and trying to distill the data into a quasi-quantitative measure of a qualitative ideal (the quality of the job done) to come up with a payment scheme that will pay participants in such a way that the industry has a long term future. Sounds a bit like Google’s task – except I have a staff of one. Feeling flustered? Yep – me too.
PhD’s are all about bite sized focussed research. Originally I was just going to concentrate on the ‘how’ of getting the data back from my little black boxes in real time in rural areas (I was thinking of using self healing wireless mesh networks made up of cheap 802.11g PCMCIA cards).
The problem is, since I had worked in the Sugar Industry as a Scientist, I also have a really good understanding of the mechanics (political, financial etc) of the industry, so there has been a growing pressure for me to advise other researchers / the industry about how to utilise the data and let the other propeller heads sort that out – but we had a major industry partner pull last year, and so I’m now left with the baby and a limited prospect of success – their is only so much that one person can do.
So I’ve taken a leave of absence while I think about the PhD, and while I’m on the LOA, I blog… Since I have an obvious interest in the how of organising data using qualitative measures, obviously search engines (and particularly Google) fascinate me – so that’s what I blog about.
3. To make contacts – the sum total of people studying anything remotely related to what I am in my University is 1 – me. Whilst I’ve spent alot of time working alone (as an Ag consultant – see some of my work at www.jaisaben.com).
I’m a gregarious person, I like working in a team, and sitting in an office alone isn’t my favourite activity. I like to hear about what other companies / folks are doing – gives my ideas about a) either jumping ship from PhD to real employment and where that might be or b) finessing the PhD and getting it back on track to serve a real commercial purpose, perhaps for a different industry.
4. To keep sane during my leave of absence to consider the above..
5. To make a few dollars helping other people handle website problems / modify code. My first paid programming stint was a football stats package written in basic when I was about 10 – so this is kind of like falling back to my first trade 🙂 While I am decadently enjoying my ‘time-off to think’ I still have to pay the bills.
There! Prob not such a quick simple answer as others – but that’s why I blog.. 🙂
10 ( actually, 11, sorry, 12) things you probably don’t know about me..
- I, like Vanessa Fox and John Mueller, love coffee – I have a special blend I make from Papua New Guinean Arabica Beans.
- I am a director of a lingerie business, and I know all about mobilon, different grades of lace and what effect the ratio fo cotton and elastane will have upon the durability of a pair of knickers.
- I love the outdoors – passions and skills of mine include horseriding, skydiving and orienteering – I have gotten as high as the state championships in orienteering, and I’ve made over a hundred jumps skydiving.
- I have travelled or lived all over Asia, the South Pacific and Europe, and LOVE cooking – especially Indian and Chinese Cooking. When I travel, I usually stay in backpackers – not because I can’t afford a hotel, but rather because I find backpackers have all the good tips for places to go that ‘only the locals’ know.
- I was once held ‘hostage’ by a Japanese crime gang in Shanghai – but made my escape by leaving my shirt behind (long story).
- I starred as an extra in the Harry Connick Jr / Glen Close remake of ‘South Pacific’ – my American accent was crap but I can still sing ‘ain’t nothing like a dame’ :).
- 95% of people rate public speaking as their greatest fear – I love it – the bigger the crowd, the better – gives me a buzz.
- My favourite food is lasagne and I think that the words ‘too much garlic’ shouldn’t exist in the english lexicon.
- I love red wine and single malt scotch whisky.
- I speak a little known south pacific creole fluently, even though I am an Australian born caucasian 🙂
- Special bonus thing you didn’t know – I do (occassionally) passionately argue a contentious point of view I don’t actually believe in myself. It’s a great way to engage the 80% of people that usually stay quiet in any discussion and get their views heard. I can be a fink ;).
- My dream job would be to become a Googler – that company has the diversity, support (both financial and intellectual) and broad focus that would really suit my aptitudes.
What about the other names?
Why am I called theDuck?
It’s detailed in my about me page, but to cut a long story short, I paid my way through my undergraduate (agricultural science) degree by being a DJ. My manager thought DJ’s had a tendency to take themselves too seriously, so he suggested I do something ridiculous to keep the atmosphere in my venues a bit fun – so I bolted a rubber ducky to a hat, and wore it every night. It wasn’t long before I was known as the Duckman.
Why am I called Dockarl?
I like reading – alot – and do pretty well at trivia nights etc. I think it’s fair to say I tend to learn new things pretty quick – I have a thirst for knowledge – I’m a knowledge-a-holic. I like to learn about anything and everything and get a buzz out of explaining all about what I’ve learnt to other people – like it or not 🙂
There is a well known guy here in Australia by the name of Dr Karl Krusielniski who has various degrees (I think Astro-physics, Medicine and Surgery amongst others) and spends his time appearing on radio and TV promoting popular science in a fun way – one of his best ‘popular research’ pieces was about Belly Button Fluff – where it comes from, where it’s been and what it does. He won an ignoble prize for that tome – read more about it here.
I had a girlfriend that thought that I reminded her of Dr Karl – she used to find it funny that while most people would be reading paperbacks at bed-time, my read of preference was new scientist or something in-depth about my latest hobby.
She was a great girl, and liked to poke fun. As such she started giving me a playful jibe (so where’d you read about that Dr Karl?) every time I started talking about some weird off-topic thing I’d learnt about recently. It all ended up being an in joke between us and our circle of friends and she gave me a hotmail address – dockarl – for me to use with pride 🙂 It stuck – I like using the name because it (like theDuck) is playful and takes-the-piss.

The honeymoon is over – Spammers have found mybloglog
Has any body else using mybloglog noticed the relatively new trend towards people using attention-grabbing pictures (usually of women, usually blonde, and usually with cleavage included) in their mybloglog avatar?
I noticed this recently when I was going through my mybloglog stats, and saw that a large number of my users were being drained away after a blogger with an animated ‘baywatch style’ mybloglog avatar, mostly centralised around the thoracic region of a surgically enhanced female form, visited my site.
Upon further investigation, I found that the blogger in question was a 26 year old male.
Upon further further investigation, I found that a large proportion (50%) of all recent visitors on his site were also males with sexy blonde avatars.
MyBlogLog – A great social networking tool – or a traffic drain?
Well – I’m thinking of removing mybloglog from my site. Whilst I love to see who has been visiting my site, it irritates me a little bit that my mybloglog sidebar box occasionally resembles the ‘mens interest’ section in my local newsagency.
Another interesting fact – I think a few of these are actually automated robots – often times the attention seeking blogger’s site ends up having some form of prominent link on their front page to another site (usually myspace, I have found) which is simply a thinly veiled gateway to porn.
These people are essentially using my site (and others) to advertise smut. What’s more, the majority of myblogusers put their mybloglog sidebar in a prominent place on their site – often prime position.
I’m no prude – but if I wanted to advertise smut on my site, I would, but I don’t, so it might soon be bye-bye for mybloglog on my site, I’m afraid.
A Descriptive term for these MyblogLog Spammers?
What to call these new attention grabbing mybloglog users.. hmm – I’m not feeling all that creative at 2 in the morning but here’s a few suggestions:-
- Blimps (Blog Pimps)
- Attention Seeking Trolls..
Help me out – someone with more creativity – please 🙂
Addendum – I noticed that Eric Marcoullier of MyBlogLog dropped by to check out this article – Eric, if you’re around, why not leave a comment? Cheers – M

Well – it is official – for those of you in the Northern Hemisphere, Summer is coming, for those of us in the Southern hemisphere, Winter is coming – and whilst I love the cool nights (it lets me turn off the aircon – by gosh it has been a hot summer here in Brisbane) I hate one thing about Winter.
See that picture above? Thats my head at the moment. The flu – and right now, I have to say, it’s got me.
Yep – Probably the only thing that is more congested than my head at the moment is the M1 Freeway – and that’s saying alot, as it’s the last day of the Easter long weekend here.
What really irks me about this is that I’ve been hitting the gym twice a day for the last two months and getting some great results – lost about 8kg so far, and, more importantly, I can run a mile in about 5 minutes.. not quite as good as the four or so minutes I once could, but getting better.
The gym kind of gets addictive, so I’m feeling a tad peeved I can’t go there without bursting into a caucophany of coughing fits.. ah well – I’d better eat some more easter eggs instead 😉
While I’m off topic, I’m going to drop this link to another of my sites – I’ve made some changes to one of my commercial sites and want to get it crawled – one of the best ways to get a site crawled in my experience is to link relatively deeply to it from another site – so, here goes 🙂
