No Justification

I awoke this morning to the news that over 100 students were murdered in Peshawar. Shot in their classrooms by Taliban Militants.

A reprisal attack for a recent military offensive against the Taliban.

What evil twisted minds can justify an attack on innocent students sitting at their desks.

There is no justification. There are no words that can be uttered there are no mitigations there is no softening of thought towards these evil men.

If you harbour any thought of justification towards this evil. Then you are evil. There is no other way to think of it.


Man needs god to exist!

Perhaps its a bit of a generalisation, but in watching people I have realised that people in general need god to exist.

They need the concept of god to…

  • make their own life have worth
  • answer unanswerable questions
  • feel like they can be forgiven for the bad they do
  • and many many other reasons

 

The very fact that man needs god to exist is proof positive that god does not in fact exist.


How to improve your dental health for free!

If you have never been told, one of the quickest easiest and certainly cheapest way you can improve the health of your teeth is to swish.

That is as simple as it is and it can be done almost anywhere. Take a glass of clean water after meals or drinks or eating any sugary food (my down fall was sultanas, I love them) and swish then spit it out. If you do it in a clean basin you may be surprised to see how much stuck food it removes.

When I say swish I mean using your cheeks to force the liquid through your teeth. It will dislodge a lot of stuff that will otherwise sit for hours and also remove a lot of, if not all of the sugar left behind. My other love was sugared coffee, had I swished after each cup I’d probably be in much better shape.

So eat drink swish and be merry!


The bible said the bible was right.

 

This is on arstechnica. Repeated here because I thought it was worth repeating.

 

“Source: The bible said the bible was right.”

Isn’t that known as a circular argument? The bible is right because the bible says its right!.

Actually I have read the bible from front to back. I see no where in the bible does it state it is correct or factual, nor even that its the word of god. That’s just what we are told.

So what you are believing in then is the word of man.

Time : is it real?

This is my theory of the non-existence of time.

Time is said to be the fourth dimension. I am going to introduce a new idea. Time is not a dimension. Time is not a thing at all. Time does not exist.

What do we know about time?

Well the first thing we know is it is hard to discuss time without referencing time. Time is integral to the way we think. So please excuse some of the circular references, I am sure you understand why.

Time moves forward. We can’t back it up, not for even a femtosecond. We also know time is dependent on gravity. As we move out of the gravity well of Earth time speeds up.

We have learned two things about time

We know time can be influenced. And, without time nothing could change. The universe and everything in it would be static.

But what is it actually. What makes yesterday different from today. What makes a second ago different from now?

The answer is surprisingly simple. Everything!

The entire universe changed dramatically in the last second and we barely noticed it. The universe you live in this very second is different to the one you were in just a moment ago. At this point you are probably thinking uh oh crazy guy. But if you will just ponder it for a moment you will know I am right.

It is different because every atom has changed, every photon has moved, every energetic action has changed. The sun and all stars have changed, planets have moved, wind has blown, electrons have moved (in an indeterminate way). Everything is different.

So now you see what I mean by the entire universe has changed. Everything in it is slightly different.

And that took time to happen! Or at least that’s the way we think of it.

Without time nothing could change. The universe and everything in it would be static.

So far all I have done is reconfirm what we call time. So now we will explore the theory of the non-existence of time.

Imagine this. Every single molecule in your body stopped moving. Every atom stopped vibrating, every electron stopped spinning. Nothing moved, absolutely nothing. Now imagine this continued for a year of everyone else’s time. For one year of normal time you were in a completely motionless state.

After twelve months, everything resumed moving. How much time would have passed for you? None, that’s right, between stopping and starting no time passed. You didn’t age, you didn’t breathe, your hair didn’t grow, and your thoughts resumed exactly where they stopped.

For you not even one second of time had passed, while for the rest of us time marched on a full twelve months.

Did you time travel?

I am going to take what I said before and change it just by one word.

Without motion nothing could change. The universe and everything in it would be static.

So time is really synonymous with motion. In fact what we call time is just our way of measuring motion. If so then why does time move at different rates dependant on the strength of gravity?

It helps to understand how we ultimately measure time. At the most precise level we measure time by counting the vibrations of an atom. An atom that vibrates at a very stable rate.

Atoms are influenced by gravity. It is my contention that the vibration of the atom changes based on the strength of the gravity field it is in. All matter changes based on the gravity field it is in. Because space changes based on the strength of gravity. Therefore a clock in orbit runs at a different rate than a clock on earth. Measuring the difference would make you think the rate of time was different. But it is not, just the rate of vibration is different.

Ultimately does this theory of the non-existence of time change anything? No it doesn’t, time is still a very important measure of the rate of change around us.

What it does do though is answer one question!

Can we time travel?

Yes we can, by influencing the rate of change of everything in our vicinity. My fanciful example above of a complete atomic stasis is one way, changing the gravity field is another way, although it is measured in fractions of a second. Possibly high speed close to the speed of light will work.

This though is a one way ticket. We can only ever go forward by slowing our personal clock (motion). We can never go back again, there is nothing to go back to. Because there is no such thing as time.

Time is not the fourth dimension. Time is what we humans use to measure motion.


Are we Gods experiment?

The major religions follow a similar line. Only the faithful shall enter the Kingdom of God. Whether it be Christianity, Judaism, Islam or many of the other major religions (excluding Buddhism and Hinduism).

But each religion makes exclusions. I mean I am faithful, I am faithful to my wife, I have faith that the sun shall rise tomorrow yada yada. yet I don’t qualify because I don’t follow their brand of faith. I must have faith in not just God but their brand of God!

They all claim to speak the mind of God, So they must be right.

So what’s the logical conclusion to this?

There is almost 7 Billion people in the world now, but they don’t all follow the same religious belief. The top ones can be broken down into a multitude of sometimes mutually exclusive sects.

Not everyone follows the same brand of religion, and according to the adherents only their own secular faith gets the right of entry into heaven. That means of the 7 billion or so people only very few actually have the right to go to heaven.

And that doesn’t include those who have already passed on.

What can this possibly mean?

Lets make some religious based assumptions.

1/ God is all knowing

Ok because of this God knew from the very beginning that he was creating people where the huge majority will end up in hell (at least Catholic Christians believe this).

2/ God is loving

What could the purpose of this be? Why would a supposedly loving God create man knowing at best most will be cast aside or at worst spend eternity in hell.

3/ God gave man free will

What does this even mean? How can you have free will when the outcome is already known?

Lets assume instead of there being one outcome there are innumerable outcomes all based on man exercising his free will.

If we assume there are as many different outcomes as there are people. So if we actually do the math on this a rough approximation is 7Billion factorial. wolphramalpha gives us

1.2550874172367861035137264048483017925786069073982… × 10^65875624912

 

Ok given the subject is God we can assume this number is a mere trifling and God can see all of those possible outcomes. In actual fact the number of outcomes tends a lot closer to infinity the above enormous number only relates to each person exercising their will only once in their lifetime. Given that each person exercises their will countless times in a day you can see how this number becomes even daunting for a god.

What have we learnt so far?

  • God created man knowing most will die wasting their life or will be punished just for being God’s creation.
  • Gods love doesn’t encompass those he considers unworthy. Plenty examples in the bible of God destroying those he dislikes.
  • God is truly great with numbers

If we can be so bold as to consider what God’s plans are and I don’t see an issue with this as if you ever ask a Christian or Muslim or whatever about God they are more than willing to tell you what they think gods plans are. So why should we be barred from considering the same question?

So assuming we wont be burned at the stake for doing what religious folk do every day we will attempt to consider what all of the proceeding means?

With so many possible outcomes what can be the ultimate goal?
With so many discarded lives what can be the ultimate goal?

To be honest I can only come up with one plausible answer. We are Gods experiment, God is trying to build the perfect human and each failed life is just one more experimental miss, discarded as the worthless life it was.

Eventually God will find that perfect being.

What then. Will God continue looking for another perfect being or will he be satisfied and turn off all of creation?

 

Where do YOU fit, Are you that perfect being?

 

 


Conspiracist Ideation and censorship

Conspiracy theorists attempt to censor research into their actions

This article on Ars Technica discusses the removal of a study into conspiracy theories due to pressure from the conspiracy theorist blogs themselves.

Here is the original now removed article. Fortunately the University of Western Australia is not so easily cowed by such threats.

http://websites.psychology.uwa.edu.au/labs/cogscience/Publications/LskyetalRecursiveFury4UWA.pdf

Now lets watch the Streisand effect do its work.

This article also introduced me to the term “Conspiracist Ideation” A great term :)


md5 is still good enough for passwords

I read a lot about how md5 is hacked and don’t use it for passwords blah blah blah

It is true that finding collisions in md5 is easy enough and brute forcing them with modern day computers is trivial.

But are they useless?

I Don’t Think So!

The following is based on someone getting access to your database because say you left the door open and they were able to inject some sql which revealed your user accounts. Sadly a very common occurrence.

The reasoning for not using md5′s as password hashes goes like this. I can brute force 5 Billion Hashes a second therefore I can crack all your passwords within minutes therefore md5 is terminally broken.

Well Yeah, That is correct if you don’t salt your hashes and you should! What is salting? Salting is adding random characters to the password to increase its complexity. It is done by the webserver or whatever program is using the password

It goes like this..

instead of

hash = md5(password);

you have

hash = md5(password . salt) ;// . means concatenate

Now if the cracker doesn’t have the salt he cannot brute force your password and rainbow tables and collisions are also out.  (rainbow tables are massive precomputed tables of cracked hashes)

The trouble with the above solution is two users with the same password have the same hash. That little leakage of information could be enough to crack the password.

So what you need to do is to add a unique salt, one per password. This then prevents two passwords having the same hash.

hash = md5(password  .  unique salt);

But this means you need to store your unique salt with your password. So if your database is hacked then your salts are also known! But it does give the bad hacker a headache they still need to brute force every password in your database with a different salt for each password. It makes it exponentially harder.

How about we add another salt to the system will that help? Yes it will!

If you add a third common salt to the system so that your algorithm now becomes

hash = md5(password . unique salt . common salt);

Then the bad hacker needs all three. As long as the hacker does not get the common salt then your passwords are safe. BUT DO NOT STORE THE COMMON SALT IN THE DATABASE!

If they have the database and get your common salt because you were silly enough to store it there then you are back to the salt plus unique level of complexity. Good but not great!

Remember this too, as a developer we can do all we want to protect our users passwords. But if users are stupid enough to use simple passwords and then share them across multiple sites then they deserve to get hacked.

To protect them from themselves when setting passwords for users always set a minimum complexity.

So go ahead and use md5 in the knowledge you are reasonably safe. Of course if they get access to your server then once again you are in trouble!

So the solution is two salts a unique and a common salt stored in a different media (configuration file)

AND insist on minimum complexity passwords.

md5 Is fast and that’s why its still a good choice for a busy server.

Of course you may have different reasoning so I’d love to hear it.

P.S. If you really want to give your bad hacker a hard time then add a counter to your hashing algorithm.

hash = md5(password . unique salt . common salt);
for (i = 0 to 1000000) {
           hash = md5(hash);
}

Big Bang – What triggered it?

The currently accepted theory for the beginning of the universe is “The Big Bang” where the universe was once crammed into a space immeasurably small, called the singularity. It then exploded and the resulting plasma from the explosion expanded and cooled and then coalesced into what we now call the known universe.

I have a problem with this. Go figure hey I have a problem with much of science!

Not that I want to hand a gimme to creationists but I have to ask the question “What triggered the Big Bang?”

Let me explain further.

Physicists tell us we can ignore the laws of physics at the start of the universe that the laws that describe our universe didn’t come into being until after the Big Bang, not long after but most importantly they didn’t exist in the singularity.

They say this because our physical laws don’t make sense within a singularity. Too many impossibilities are raised. but in doing so they admit to one rule still applying. the rule of logic.

If the rule of logic applies. Hence we can discuss the singularity then surely we can discuss what gave rise to the Big Bang.

So now that we have defined it is ok to even discuss the Big Bang or more precisely the singularity that ‘existed’ before the Big Bang then we can discuss the trigger.

When something changes, no matter what it is, whether it be the path of a molecule of air or the thoughts of a blogger or an nuclear explosion. it must be triggered by something. That something can be a lit fuse or a new thought or butterfly flapping its wings or a fracture or an impurity.  Nothing changes without something triggering that change.

So what changed that caused the singularity to suddenly destabilise the singularity and make it burst?

The Heisenberg uncertainty principle states that we cannot know both the speed and position of an element at the same time we can know one and only approximate the other. What is not clear is that the element does have a speed and a position we just can’t measure it.

Can this principle apply to the singularity. I don’t think so. From outside the singularity nothing exists and therefore there is no reference frame to make any measurement or observation from.

The logical necessity of a trigger, an external influence on the singularity necessitates that there must be an external force acting on it, that the singularity cannot just come into being and then once it has come into being spontaneously explode.

It is my contention this precludes a singularity, that there was no Big Bang.

That only leaves alternatives. Interestingly it gives us a view at the end of the universe, if the universe did not arise from a singularity perhaps it arose from a big crunch. That the universe is constantly expanding and contracting, this is an old theory that  many discount but this oscillating universe does not need a singularity.

 

 

 

 


Googles Instant Pages

Google Instant Page

Amit Singhal, Google’s head of search ranking, announces Instant Search at an event in San Francisco

 

Googles Instant Pages

“Google is ready to make waiting for Web pages to load a thing of the past—at least for those pages found using its search engine and the company’s Chrome browser. As a user peruses the list of results returned in response to a query, the browser will fetch and load in the background the page it considers most relevant. If a person does click that result, the page will load instantaneously.” src – technology review

What’s Special about this?

Firefox has had prefetch for a long time now. It was damn annoying. If you had a slow connection or limited bandwidth this could become very expensive.
I disabled prefetch a long time ago because it was detrimental to my surfing.
Rarely is google so good that the first result is the one you want. Therefore it will often be fetching something you don’t need. This smacks of an apple/microsoft like announcement. More marketing than truth.
If you believe google is so good then just click I am feeling lucky. which send you to the first website in the search results.

SEO (search engine optimisation)

From SEO point of view it means a site would get inflated hit figures for hits they never actually received because the user decided to click the second or subsequent link

Malicious Sites

Malicious sites could conceivably give you a virus even though you look at the result and think “Hey I ain’t going there it looks suss to me”

Cookies and Privacy

When google and Firefox combined in the past to do this I was tipped off by sites requesting to place cookies on my machine. even though I never visited the sites. I never accept third party cookies, to me this was an invasion of privacy, Hence the main reason I disabled it.

 

Dumb move Google and even dumber announcement. it so smacks of Steve Jobs*. Was he hired as a consultant on this?

 

* In case you didn’t realise it this article was written before Steve Jobs passed away
