Fwoomph!
Another application.
Into the furnace that is the world of HR.
With luck it’ll be borne aloft on the updrafts of burning applications, else it’ll fall into the fire and in burning, will aid in bearing another lonely application up to the heights of employment. Such is the cycle and the way of things.
May your CV always soar, but be comforted that in the conflagration of the many some few may taste success.
Yup, slow day at work.
A first-grade teacher, Ms. Brooks, was having trouble with one of her students. The teacher asked, “Harry, what’s your problem?”
Harry answered, “I’m too smart for the 1st grade. My sister is in the 3rd grade and I’m smarter than she is! I think I should be in the 3rd grade too!”
Ms. Brooks had had enough. She took Harry to the principal’s office.
While Harry waited in the outer office, the teacher explained to the principal what the situation was. The principal told Ms. Brooks he would give the boy a test. If he failed to answer any of his questions he was to go back to the 1st grade and behave. She agreed.
Harry was brought in and the conditions were explained to him and he agreed to take the test.
Principal: “What is 3 x 3?”
Harry: “9.”
Principal: “What is 6 x 6?”
Harry: “36.”
And so it went with every question the principal thought a 3rd grader should know.
The principal looks at Ms. Brooks and tells her, “I think Harry can go to the 3rd grade”
Ms. Brooks says to the principal, “Let me ask him some questions.”
The principal and Harry both agreed.
Ms. Brooks asks, “What does a cow have four of that I have only two of?”
Harry, after a moment: “Legs.”
Ms. Brooks: “What is in your pants that you have but I do not have?”
The principal wondered why would she ask such a question!
Harry replied: “Pockets.”
Ms. Brooks: “What does a dog do that a man steps into?”
Harry: “Pants.”
Ms. Brooks: What starts with a C, ends with a T, is hairy, oval, delicious and contains thin, whitish liquid?”
Harry: “Coconut.”
The principal sat forward with his mouth hanging open.
Ms. Brooks: “What goes in hard and pink then comes out soft and sticky?”
The principal’s eyes opened really wide and before he could stop the answer, Harry replied, “Bubble gum.”
Ms. Brooks: “What does a man do standing up, a woman does sitting down and a dog does on three legs?”
Harry: “Shake hands.”
The principal was trembling.
Ms. Brooks: “What word starts with an ‘F’ and ends in ‘K’ that means a lot of heat and excitement?”
Harry: “Firetruck.”
The principal breathed a sigh of relief and told the teacher, “Put Harry in the fifth-grade, I got the last seven questions wrong.
It’s been a while.
As predicted by more than a few people, my dedication to mikesflying.com waned after a couple of months. This will not do. I’m resurrecting the site and the blog as of now – with a new resoloution to blog at least once a week – if not more. Luckily now I’m stuck into Phase 2 of my training and I’m actually being allowed behind the controls of real aircraft I’ve got a whole lot more to write about. I can’t guarante insightful, eloquent or even particularly interesting prose, but I can guarantee that I’ll enjoy writing my humble submissions.
So, given that I’m going to keep this fairly concise, I’ll fill you all in on the last few months:
Feb: Study leave, revising for JAR exams.
March: Sat JAR exams and…
Passed them all! marks as follows:
This give a nice healthy average of 90.2%.
April: Start Flying! Complete my First solo on my 10th hour – and christen my new callsign: ‘Cygnet 315‘
May: Not such a happy month. The month got off to a bad start when I broke up with Andrena. It’s a long an involved story, and for both of our sake I’m not going into it all here. Suffice to say that being run-off-my-feet busy with flying and work here in Phase 2 leaves me wonderfully little time to dwell on it all. On the up side I’ve accrued a few more solo hours and I’ve also started Instrument flying in anger.
Well, that’s you brought quickly and roughly up to date, I’ll be back soon!

And now Useful Expressions for those High Stressdays
Well, in an effort to aid my revision for rapidly approaching JAR exams I’ve decided to attempt another technical post, especially seeing as my rough attempt at explaining SALR and DALR (HERE) seems to be popular with good old search engine traffic.
This week I will mostly be discussing Logic gates.
I’m going to skip the construction of these little computing wonders, though for interested parties they’re constructed out of anything from levers and weights through to MOSFET’s (Metal Oxide Semiconductor Feild Effect Transistors) on intergrated circuits such at the processor in the very computer you’re reading this on.
The great god of Wikipedia tells us that the first properly functioning Logic gates were to be found on Charles Babbage‘s Analytical engine. These were actually fairly complex constructions of pegs, barells, levers and all manner of mechanical trickery. Though the basic principles of operation from these gates to modern-day electronic gates is identical. It’s this principle I intend to explain and explore. I’m going to stick to purely electrical logic gates
I’m going to skip the lesson in the Binary (base-2) system and simply summise that as far as we’re concerned if a wire has a potential difference accross it then it’s Logic (Binary) 1, and if it has none it’s Logic (Binary) 0.
I suppose I’m also assuming that we know what a potential difference is, but for the purposes of this article we can define it thus:
If a wire has a potential difference accross it then when it is added into a complete circuit, electrical current will flow in the wire
So, our logic gates look at a selection of wires and (based on their state as on/off – 1/0) create a logical output of 1 or 0.
There are several types of Logic gate which, surprisingly, perform several types of comparason.
Firstly, I’ll introduce the OR gate.
An 'OR' gate
Named because it will return a ’1′ if any one of it’s inputs are ’1′. So if either the top OR the bottom input is 1 it will output 1 as well. If both are 1 it will output 1 but if both are 0 it will output 0.
The AND gate is next, again it’s function is quite simple.
An AND gate
It’ll only return ’1′ if all it’s inputs are also 1. So if the top AND bottom inputs are 1, it will output 1. If not it will output 0.
Next we’ll introduce the NOT operator. This little fellow inverts the logic on a wire. For example, if an input is a ’1′ a NOT operator will make it a ’0′ and vice-versa.
The little circle is the 'NOT' operator
So, using this NOT operator we can invert the output of our AND gate giving us a Not-AND gate or NAND gate.
A NAND gate
A simple way of thinking of this is just to treat is as an AND gate and then reverse the output you get. This will only return ’0′ when all of the inputs are ’1′.
A it follows that you can add the NOT operator to an OR gate as well, making a Not-OR (NOR) gate.
a NOR gate
There’s one other family of gates we need to know about, and that’s either-or gates. They’re basically OR gates but they won’t return ’1′ when both inputs are ’1′. You can get both a XOR gate and a XNOR gate.
An XNOR gate
An XOR gate
Ok, so that’s all our gates. Nice and simple. Next post I’ll go into where they’re used and run through some examples of simple logic circuits. Even some tricks we can pull with the gates to make them store data for us.
