All of human knowledge in my inbox?

After doing some manual restoration of emails from one user to another in DB Mail I suddenly found that the estimated usage was quite large. Approximately 17 exabytes (an exabyte is 1024 petabytes, which is 1024 terabytes, which is 1024 gigabytes).

This is what it said about my inbox:

Opening connection to database…
Opening connection to authentication…Ok. Connected
Info for user [rhys]User ID : 3
Username : rhys
Client ID : 0
Max. mailboxsize: 0.00 MB
Quotum used : 17592186044339.48 MB (inf%)

And what makes it even more interesting is this:

“It estimated that in 1999, the total of all human knowledge, music, images and words amounted to about 12 exabytes.”[1]

And the compression must be pretty good too, after all it is fitting on a volume only 200 gigabytes in size!

Unfortunately I’m guessing this is a bug in how it updates quotas. Pity, it would make up for UQ rejecting my request for access to the library (which I just found out you should be able to get for the first twelve months after you graduate).

A look at the environment

This is the first in an extended series of articles The Mill is covering examining the environment. I’ll take a logical approach to defining the environmental problems that face our planet and look at some of the potential problems with our current model of thinking.

Global Warming (which I assume is the subject of Al Gore’s An Inconvenient Truth) is probably the most prevalent environmental concern that people today are aware of. And why not? It’s simplicity (in summary, not the entire theory) is just right to get into the brains of the masses: “It’s going to get hotter, and heat melts ice”. Unfortunately it focusses on the symptom, rather than the problem.

The second issue with Global Warming is that it is being treated as scientific fact as opposed to theory. Although I suppose that this is a consequence of people’s false perception that a theory is inherently not true. Instead, I’m going to work on the definition of theory given to me by my high school biology teacher (Bill Stephenson):

“A theory is the best explanation for a phenomenon at the time”

It takes time and a substantial amount of evidence for a theory to be considered fact. Yet with the sensational nature of Global Warming, it is easy for the media to get these two aspects confused.
So what are some of the problems with global warming? It’s a hard thing to prove with only circumstantial evidence. In order to accurately recognise the symptom you need to identify the pattern and prove causality. Because we are talking about weather patterns that need to be considered on a geological timescale, we need to also have taken the readings on the same timescale. That just isn’t feasible. Additionally the range of areas covered and human error need to be removed from the equation.

So rather than trying to prove or disprove Global Warming, I am instead going to look at other more solid issues. Those issues in turn are related to how it is believed global warming works.In simple terms our problem is sustainability. As far as the environment goes, it is probably the single most important thing to think about today. Thinking about sustainability allows us to look at the root cause of problems, rather than simply looking at the symptoms and not doing all that much about it.

During my Masters degree I undertook a couple of courses on sustainability and whilst I am the first to admit I’m not an expert (Henry Ford said that to think of oneself as an expert, stops innovation) I feel that I have enough of a background to get the ball rolling. Sustainability was probably the most interesting thing that was covered in my degree and applying the thinking behind it is not too hard.So, let’s deal with some facts. We have a growing population with finite resources. All resources are finite, but some resources are able to be re-used rather than just consumed, or the supply is sufficient enough that it can be considered close to infinite for our purposes (such as the Sun, which one day will stop working, but when it does if we haven’t moved to another region of space there’s not much we can do anyway).

Fossil fuels are finite. They don’t renew at a rate faster than we are consuming them. They will run out in time, and our dependency on them will ensure total chaos (I’ll go into this in more depth in a later article). As a consumer-driven society we are adding more and more to landfills every day. Not only does this take up precious space, but this is a sample of resources that are no longer fit for use.

To deal with the issue of fossil fuels we need to move to alternative, renewable fuel sources or reduce our consumption of these fuels (although this is a temporary solution). Landfill issues need to be solved purely by reducing waste. Smaller packaging that uses less resources is the way to go here. Additionally recycling and re-using resources that would otherwise have gone to landfill is vital.

There are plenty of other environmental issues to discuss and it will be tough to get into all of them (but I will try my best). In subsequent articles I will go into more detail, but hopefully this provides an adequate introduction to the sort of things that I will cover. As always I encourage your comments.

Shock horror! Yet another of life’s pleasures may increase the risk of cancer

Well, today the Salvation Army has decided to wage war on alcohol, saying we should be putting warning labels on alcohol to warn people that it increases the risk of cancer. Unfortunately, the article doesn’t provide any references to the research that they are referring to, but that won’t stop The Mill.

The first thing that comes to mind when looking at this sort of research is just how scientific the approach is. There are so many factors that need to be kept constant to accurately measure an increase in risk. First, your group of people have to have the exact same existing levels of risk. Then, you need to ensure the only factor that may increase their risk is alcohol. I’m sure we’ve come a long way in the field of research, but I just don’t think we can adequately do this.

And then there are the countless other things that they (people who aren’t me) say increase our risk of cancer, like standing too close to power lines, microwaves, mobile phones and all the other fun gadgets that make life great. Oh, and then there is smoking!

So when you have your perfect test group you have to monitor and control them long enough to see whether their risk level increased. And the best way for that to happen is to wait until they get cancer. But the actual cause of the cancer isn’t what they are looking at, merely risk, and anyone can fudge those numbers.

So now I have to ask whether the Salvation Army could have an alterior motive to reduce alcohol consumption. Perhaps they are marketing a new line of non-alcoholic drinks, but more likely they deal with a number of other problems which may be related to alcohol. Perhaps they want to encourage “winos” to stop spending their money on booze and instead buy food, clothes and maybe even take a shower. Personally I don’t think cancer is high up on the list of concerns faced by the homeless.

I remember being told by a reasonably reputable source (I don’t remember who they were, just that they were reputable) that just about everything can cause cancer. The trick it seems is to die of some other way before cancer gets you.

Of course, boozehounds have many other ways that are likely to knock them off before cancer gets them. Anything from car accidents, bar brawls, nude drunken swimming and playing chicken with cars can lead to a premature, cancerless death.

So, why not eat, drink and be merry and enjoy life while you are living it? After all, death is inevitable (probably).The Mill encourages drinking in moderation. If you must binge drink, be sure to do it with friends who can help you and not leave you in a bus shelter or gutter for the night. The Mill also acknowledges the plight of the homeless and in no way suggests that all homeless people are constantly off their face on booze.

But I don’t want to Hibernate

Here at work we recently purchased a Dell laptop. It’s something that I wouldn’t recommend, but it was incredibly cheap, we needed a new laptop and it seemed like good value.And so far it has been, at least for the person who primarily uses it. Having used a Dell laptop before she is familiar with the exact keyboard layout. Performance wise it is quite good (although it is also chunky, which is what happens when you combine cheap and powerful).

Anyway, Dell seems to take it upon themselves to make some changes to the configuration that are quite annoying, including changing the resolution of images so they look all pixelly!One of the more annoying settings is “Hibernate” as the default shut down option. Now, as a laptop the hibernate option is quite useful, but I’m a purist and like to Shut Down Windows whenever I’m forced to use it. To fix it so it will use your last setting you need to edit the registry. (Of course, this problem only affects you if you use the “Old School” Shutdown Dialog, which you are forced to use if you are a member of a domain.)

CAUTION: Editing the registry may screw up your computer, particularly if you do anything other than these instructions, even if you do it could blow up, harrass your family or whatever. The point is, don’t hold me responsible. Do this at your own risk. If you aren’t prepared to do that, pay someone to take the risk for you.

To fix, run regedit and look for the following key:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\System\Shutdown

The name, value pair you want to change is HibernateAsDefault. This will be 0×00000001 (1). Right Click and select modify. Change the value to 0 and click OK. The change will take affect immediately. Go on, try to shut down. For those of you who would prefer it to be the default option, change it to 1 instead.

I’m not quite sure who would use this functionality as most laptops can detect when the lid is closed or the power button is pressed and you can define the action you want for these. Hell, this Dell (hehe, a rhyme) even has Hibernate as a function key (and an eject CD function key, which seems redundant with an eject button on the drive itself).

Hopefully someone will find this useful. I know that I would have preferred a Google Search to answer my question.

Thank you for not smoking

After seeing the movie Thank you for smoking I was quite curious as to whether less people were taking up smoking. In Queensland, smoking has been banned from all areas where food is served, suddenly making bars habitable again.

Victoria youth smoking figures seem to be at about half of the equivalent 1999 poll. Let’s just hope that this isn’t a poor sampling and is actually an indication of what is going on.
