Most people have some idea of how to create a file on their computer. Whether it be a Word document or a simple text file. However, most people have no idea how some of the cool things get done in the Unix and Linux operating systems and I hope to share one very small program called “ln” that allows you to do some really cool stuff.

First a few examples:

There are two types of links on Unix/Linux and we’ll get to both. The first is called a symbolic link and would normally be used to link a directory. For example: You have a folder that has gotten quite a bit larger than you expected and you need to move it. You have a lot of users or perhaps a website using the folder so moving it seems to be more complicated than you want to think about. Lets see the steps involved:

1) You find where you want to put the information.

2) You issue the command: mv currentfolder newfolder
Where currentfolder is where it is right now and new folder would be the black jackroulette game downloadtop kasinolotto spieleninternet gewinn spielepc slotsgiochi casino gratiscasino club bonuscasino tycooncasino online gamesrealistisches online kasinoonline gewinnspielehoyle casino gamescasino baccaratatlantic cityslots spielencasino gamblinggratis casino bonusroulette regelcraps spielslot maschinen online spielencasino online ohne einzahlungcasino games 2007keno online spieledeutsches online casinoroulette onlinespielinternet gewinnspielonline kasinoscasino online deutschlandspielen kasinoroulette spielecasino online liveslots softwareonline casino hamburgonline casino geldbeste online pokerparty poker signup bonus codetexas holdem gratis downloadpoker regeln blattinternet poker gamesbwin poker bonusparty poker deposit bonuspoker superstars online spielenpoker regeln blindsgratis poker depoker online spielen ohne downloadonline casino pokerexpekt poker bonusstrip poker spielparty poker de full path to the new location.

3) You create a symbolic link to the new location back to the old location. Lets assume we’re in the folder where the original was before we moved it. issue the command: ln -s newfolder currentfolder

So in step 3 we created a symbolic link from the new location back to the original location. Now your site or systems are back on line and no one even knows you moved the data.

So whats with this hard link stuff? Well, hard linking is done with the “ln” command as well but without the -s on the end. What it’s used for are situations where you have a file that you want to share between multiple users but you don’t want to duplicate it by copying. You’d like them all to be able to make changes to it and when those changes are made you’d like for everyone to all see them.

To do this we’d create an original file on disk in some folder on the computer. Then we’d issue the command:
ln originalfile.txt newfile.txt

Where the originalfile.txt is the full path to the name of the file you wish to link to and newfile.txt is the full path to the new linked file you want to create. NOTE: Relative paths work as well here.

There are many cool things you can do with the link command and as an example Apple has released their latest Leopard OS to the world. One of the things it has is a very cool thing called Time Machine that not only backs up your data but provides a very cool interface for restoring things. In fact its so cool that the next time a friend comes over it will be the first thing you show them. Now when has that ever been the case? Hey Joey, take a look at my backup!

Anyway, the primary thing that allows Time Machine to do its job are hard linked files.

When getting into the higher levels of mathematics, it is necessary to completely understand what a function is and how you can use it. This blog entry will discuss this fairly simple topic and attempt to explain it in such a way that someone not versed in mathematics might understand it.

By the way: If you don’t want to read all this, click here to just watch a video

Before we get started on what a function is, I wanted to discuss very quickly an example of why functions are important in Physics, Chemistry and yes, even business. Lets say that you are given the task of watching someone drop a baseball off of a very tall building about 450m tall ( yes very exciting! ). Your task is to sit and write down height values for every 1 second of its fall.

Since you are very board and aim to please, you quickly pull out your pencil and you start plotting points. These points might look like the following graph.

Note that in the above graph, we’ve plotted our points as the blue dots but there is also a red curve connecting them all. If you also refer to the left margin of the graph, you’ll also notice that there is a function there of 449.36+.96t-4.90t^2. So what does all this mean? Well lets dissect:

First of all, the dots represent a real world example of storing data. At some point however, people got tired of sharing all this data back and forth and started looking for other ways to represent the same facts. I mean, if we could see the same graph with a short function, who wants to sit and take a bunch of numbers and re-plot them to see what is going on? So, a function is nothing more than a mathematical representation of a path. At some point, someone was looking at all those points and said, hey Honey, take a look! If I take the number 1 and plug it into this formula, it puts a point in the exact same place as my data point. And a 2 does as well. So now, when Joe calls I can just give him this function and tell him to pick a point in time, plug it into the function and out comes the distance above the ground! She was very impressed.. :-)

So, a function is nothing more than a formula of sorts, where you plug in an x value and outcomes our y value. Just an easier way to deal with sometimes complex sets of data. However, in order to call your new function a function you must first test it by using the vertical line test. If you plot your points and at any time a vertical line dissects the graph in more than one place then you don’t actually have a function.

Also note that there are two key terms associated with the function. Domain and Range, in which the Domain consists of your x-values and the range consists of all the possible outputs of your y-value. So for example, in our case of dropping something off of the building that is 450m tall, a value of 500m for the range wouldn’t make any sense. At the same time, if it took 9.8s to fall to the ground, looking at a time of 15s wouldn’t make any sense either. So we’d say that our domain (our x value) consists of all points between 0s and 9.8s. Now, if we were to plug in 0 into our function it would give us 450m, and plugging in 9.8 would give us 0 height. So we’d say that our domain values that are valid are between 0 and 9.8.

Obviously, our original plot graph consisted of you taking 10 readings as the object fell to the ground. What happens tomorrow if I were to come to you and tell you that I need to know exactly where the object is at 1/2s intervals? Well, you’d have to get out your pad, run back to the building and drop another object so you could collect more detailed points to provide to me. What fun!

Functions to the rescue! What if I told you that I could give you a function to represent that objects path to the ground and you didn’t need any data points at all? And no matter what time interval you plug in, it will tell you precisely how high above the ground it was? Well, if you aren’t crazy over all this data collecting, you’d probably be very happy. No more collecting data, we have a FUNCTION!

We now know what a function is and I suggest you make sure that you understand the concept completely for a number of reasons. 1) its absolutely the simplest concept you’ll deal with in Calculus and 2) Its a necessity to understanding anything else I talk about in future discussions of Calculus.

Well, they’ve about done it. They have almost turned the Internet into a dead zone. I have a blog and a forum located on this site that I use and enjoy getting feed back on, both of which I’ve now had to shut down. No one can create accounts on my forum without me personally approving them and that is becoming a problem due to the number of spammer faggots posting new accounts on the forum daily. They of course can’t create the accounts and can’t get their ill-formed garbage for anyone to see, but none the less, they waste their time as well as mine trying to get the accounts created.

Then, I open my email today and have 80 comments on my blog that I had to go through and delete because another bastard posted his junk on there. This site is not a job for me and I can’t allow it to take up all my time just trying to keep it clean. So now I’ve had to turn off the ability for anyone to post comments to the blog. What fun this has become!!!

I really don’t understand how these people are getting past all the security features such as emailing you authentication codes and pictures you have to describe before you can even create the account, but somehow they are. Hopefully some time soon I’ll find a way to stop them for good and can open things back up, but for now the spammers win. Or rather, they loose. Do they not realize when we all get so tired of this shit that we stop fighting that they loose for good? And who the hell is paying these faggots anyway?

Anyway, I”m a little upset as you can tell. I think we should open up burning at the stake again and throw all these bastards on top of each other and light them up.

I am not going to claim that I know everything there is to know about Quantum Physics or Quantum Computing but then, who can? It would be like making the statement that there is a single person on earth that understands the current IRS tax code here in the United States. There are lots of assumptions and a lot of things stated as proven fact, but in the end, there is very little truly understood.

Take for a moment superposition: This is a word used to try to explain the fact that a particle exists in more than one position at the same moment in time, and that only the measurement of that particle causes it to choose one position over another. For example: In an earlier post I tried to explain the 2 slit experiment in which physicists say that a single electron fired towards 2 slits, travels through both slits at the same time. And that only our measurement (or attempted measurement) causes it to choose a single hole or the other. See my earlier post as to why I think this might be wrong, but for now I want to assume they are correct.

In today’s world of computers, we typically use 8 bits of memory or storage, that is made up of either a 0 or a 1, to represent a single character. This combination of 0’s and 1’s allows us to represent massive amounts of information and processes. Computer programs use this information in order to determine what a user just typed at the computer keyboard, or what is currently displayed on the screen. Now watch this!

Quantum Computing is attempting to use the actual elements to represent this 0 or 1 state by measuring the particles spin or state and using that value to represent information. But as we just stated above, in the world of Quantum Physics, a particle exists in 2 states at once. Physicists use this behavior to state that its now possible to represent an entire character set with only 8 bits. In the old method, you would have 2 states multiplied times 8 positions which yields 255 different combinations. In the Quantum Computing methodology, they claim you’d only need the 8 positions, since all 8 particles are representing all possible combinations at once.

They go on to tell us that it will be possible to have computers that can out think time itself, due to the fact that Einstein’s theory of relativity states that nothing moves faster than light, yet these Quantum Physicists claim that on the single particle level everything does.

Back to the time Computer: So, lets consider for a moment a computer made from particles that are interpreted via the rules of Quantum Physics. What would it tell you? I want to store the word “mouse” in its memory. How would one accomplish this? According to these guys, the computer would require a lot less memory to store the entire word, due to the fact that any 8 bits would be able to handle this job easily where before it would take a lot more using a computer built today. But thinking through the logical use of this computer gets a little crazy. I mean, lets think of today’s computer that could possibly exist in both 1 and 0 at the same time, and only the measurement of one of those particles causes it to Choose… Keyword: Choose… In other words, Quantum Physics states that we can NEVER know the state of a particle until we measure it, and that the measurement itself will change other aspects of its existence. Therefore, we’d have “mouse” that we wanted, but until we measured each bit, what would we get? How would we force the particles to provide the data we wanted when they would obviously, according to their own rules, have to have every possible combination at once. It would appear to me that we might just as easily get the word horse, or dog or cat than to get what we wanted, out of the system.

I’m sure that there are many aspects of these Quantum Computers that I just don’t understand and may never be able to understand. However, I feel that at the moment, we waste a tremendous amount of time and money, in search of magic. Either Quantum Physics is wrong, which is what I lean towards, or Quantum Computing just makes no sense.

Who’s to know? At this point, no computer has been built using this technology and the tests that have been done to show it works have been flimsy at best. Yet years have already been invested and most likely billions of dollars moved towards making the illogical logical… After all, a computer is 100% logic and nothing more…

After my last post I’ve had a number of people giving me scripture that prove me wrong here or there and I wanted to document which ones and what they say in order to portray a fair and balanced thread. The main topic of today’s post will be the first 3 days and the remarks about how I just don’t understand the scripture. First a refresher on my previous statements.

Basically, it is my opinion that the Bible, while historical in content, contains no revealing comments what so ever that only god could know. As an example I covered the first 3 days and the fact that there was no Sun, yet we had morning, evening and plants growing here and there. To refute this, people have been telling me that God is light and he did not require the sun for things to grow. They also like to tell me that plants and life could exist without the Sun and therefore did not require it to get started. There is also the line of logic that states that a day was not a 24 hour period of time (this of course to try to explain why bible time provides the earth and the entire universe with a mere 6500 year age).

In response, I am going to read directly from the Bible and provide commentary that you can ponder if you’re interested.

1) In the beginning God created the heavens and the earth. This simply tells us that God created everything, yet really doesn’t give us a time line for any of it taking place. From this we could surmise that the earth and universe are indeed older that 6500 years of age, but that nothing should have lived or existed during this time period since he had not created anything yet.

2) Now the earth was formless and empty, darkness was over the surface of the deep, and the Spirit of God was hovering over the waters. At this point, God seems to be floating about the earth, but it further defines that the earth was without form and empty. Water seems to be the only thing it speaks of existing at this point. The key element to pickup from this statement however, is that their was darkness. If indeed God “IS” light, then there would not have been darkness during this floating period. To further clarify this, the claim was that plants and life existed from his light and not the light from the Sun. If this were indeed true then his light would have to fill the entire sky since the earth is not flat and a single source of light could not have produced the same effect across the entire surface.

3) And God Said, “Let there be light”, and there was light. God saw that the light was good, and he seperated the light from darkness. God called the light day and the darkness he called night. And there was evening and there was morning - the first day. This verse creates quite a few problems in a number of areas for those trying to make verses written before man understood the planets, into fitting what we know today to be fact. First of all, God made light. This further refutes the claim that “God IS Light”, because it would mean that he was creating himself. Secondly it speaks of him naming night and day, yet we understand night and day to only be those periods as the earth rotates around its axis and the sun appears to set and rise, when in fact that is not at all what happens.

We also know that light is either on or its off, or its hidden in the case of our Sun and rotation. For him to have created night and day without the Sun, he’d actually either have to not be floating on earth as the bible says and be off somewhere in the distant, or he’d have to be turning himself on and off like a christmas light to give a similar effect.

The bible makes it a point to meaure this period of time as 1 day, morning and evening, not simply a period of time or some other means of measurement. As stated in earlier blogs, I think this was done to show how powerful god was, but it makes no sense for a number of reasons:

First, a day as we know it is a man made unit of measure to mean when there is light. More definately when the Sun is shinning, and more to the point, when the side of the earth you happen to be standing on is pointed at the Sun. So unless you were standing at a specific point on the planet, to call something day would have no meaning at all without the Sun existing and the earth spinning. Yet, none of these simple facts of reality exist in the bible. In fact, it is very obvious from many other versus in the bible that the earth was indeed flat and the Sun actually rushed around it in order to come up again on the other side. Here are a few versus for you to read about the planet actually being flat: Isaiah 11:12, 40:22, Revelation 7:1, Job 38:13, Jeremiah 16:19, Daniel 4:11, Mathew 4:8, Psalms 104:5 Ecclesiastes 1:5.

Note, that despite people’s comments about the bible stating the earth was round, or a sphere, there are no actual verses that make these claims. Its actually quite clear the people that wrote the Bible truly believed that the earth was flat and everything we see revolved around it.

And God Said, Let there be an expanse between the waters to separate water from water. So God made the expanse and seperated the water under the expanse from the water above it. And it was so. God called the expanse sky. And there was evening and morning the second day. On this day God supposedly created the atmosphere, yet it appears to me the people really didn’t understand what the atmosphere was when they wrote this. They talk about water in the sky like they believed their was a great ocean above them and it spilled out when it rained. And that God kept them seperated as if they were two different bodies of water. Again, there are no earth shattering revelations in this verse so we’ll just move on.

And God said, Let the water under the sky be gathered to one place, and let the dry ground appear. And it was so. God called the dry ground land and the gathered waters he called seas. And God saw that it was good. Then God said, Let the land produce vegetation:… You get the point. Again, we’re still marking each period of time with a morning and evening which refutes all the claims that these days were longer than a single day. It specifically states that god named day and night and that he named them after light and dark. So the constant remarks about how these were longer than a single day, seem to go against the statements in the book completely. Its also entertaining to me that God created light and saw that it was good. Did he not already know that it was good? And since we know now that light only comes from the burning of stars, exactly how did he create it without the stars being in place. The bible never speaks of him transfering his light source over to that of the Sun later on.

We also have vegetation growing without the Sun, moon, stars or anything else. Only the light source of god which would have to have somehow lit the entire sky in all directions and provided just the right amount of heat to let things get to cooking. All very strange that he’d disrupt the entire universe during these early years and now be completely gone to never again bother anything. Its also quite strange why if he truely created the universe that he’d have caused the entire thing to expand instead of just having things hang in the sky in one place for us to view. In fact, for what specific purpose did he create all the stars and the Sun? You could argue the Sun for keeping us warm, although that is quite stupid, due to the fact that he could have just left the original light source in place since it was obviously perfect for our existance.

And finally, on day 4 he finally creates the Sun and stars and the person that wrote it never mentions anything specific. Only that he created them and that they would govern night and day, yet he never mentions how night and day existed without them. Total oversite if you ask me! Consider that if God was your source of light and he was making night and day, he was only doing it to entertain himself, since there was no other reason for it to happen. Also, since he was the light source, he was actually having to turn himself on and off every 12 or so hours in order to make himself have a night and day. Then he pitched in the entire universe with all the stars and moon, and Sun at an instant, all in perfect balance and expanding forever.

Its all quite strange to me how today, people go to church and listen to all the sermons, and give their money like blind men doing as they were taught. NEVER, picking up the book and reading it to see what it really says. I take a lot of heat because I actually read the book and question what it says. Most people tell me that I’m not suppose to question, I’m suppose to just believe! That I can’t possibly understand God’s mind, so don’t try. All the while being completely blind to the fact that they’re in a cult. Cult leaders look for people that they can manipulate and keep under control. They can convince these people that they shouldn’t ask questions and should just believe his/her every word. Telling the people that they speak for God and explaining to them what he wants them to do, but without any real meat to the story. Oh, and don’t forget that old parental trick, fear of pain! You will go to hell if you don’t believe in Jesus!

Christians are quick to tell you that the terrorists are criminal, they are evil itself. Yet, not a single one knows a thing about what it would take to believe in something so much that you’d be willing to die for your god. These people don’t blow themselves up to be evil, they do it because they truely believe their God told them to do it. There isn’t a Christian alive with that kind of faith. Yet, its faith alone, because the terrorists are no better than the Christians with their god as they also practice the same blind faith.

People do not want to be alone, they don’t want to accept it. As a result throughout mankind’s history, we’ve created religions of all kinds to help us feel better. These religions have mainly served to help kings rule its people and to keep people scared and in constant search of God’s favor. They continue to pay a church that has never really done a thing for those that pay. Its all a mind game to make them feel better and nothing more. Show me a single person that lives a more gifted life than me, just because they go to church, give them their money and GOD rewards them. If God does exist, he doesn’t care about anything that is going on down here. We’re but a virus that has started growing on the planet and thinks that it’s important. We’re only important to ourselves, and cornered we’ll more than prove that.

Its a shame that we kill each other and take each others rights to live in the name of religion. We should all just live in peace and stop trying to harm each other. When a man steps up and says lets fight, we should only fight to have him sit. ALL Wars have been waged and fought by the people, as a result of the actions of a single Man thinking himself King. People follow and do as they are told and there are those that take exteme advantage of it. We should all just say enough, sit down and shut up, let us exist peacefully!
