Positive Feedback

Engineers are one of the best people to have around or even sit around. Why? engineers offer solutions, and do not have empty words, despite been simple. Dressed simply in jeans and t-shirts, engineers will solve your problems without lots of bureaucracy , like management.

Well, I discovered this recently when I was sitted in a roomful of communication engineers at the just concluded Africa Interconnection and Peering Forum. In a rare opportunity given to me to voice some opinion, they handed me a microphone, but when I tried speaking, the sound system responded with a high pitch whistle. Several attempts resulted in the same high pitched whistle. The engineers told me to move a few metres and the whistles dissapeared.

Demons! That would be the response of a priest, if he chose not to blame the devil for the same happening in a church, and which it more often than not happens. Well, the priests will be saddened to learn the devil is usually busy elsewhere, probably attending bendover sessions (don't ask me what these are, ask your pal who has earned enough frequent club-bing points) somewhere in the world.

Positive Feedback, is the answer to this natural phenomenon as the engineers will tell you. To those who were busy day dreaming of perfect dates in your physics lesson, positive feedback occurs when the microphone is held close to a speaker. The speaker has an inaudible high pitch which the microphone captures, sends to the amplifier, gets amplified and send back to the speaker higher than it was. This continues and the resultant high pitch occurs as long as the microphone is held at this point. To sort this out, you have to maintain a minimum distance from offending speakers.

For you to know but not necessarily remember, positive feedback is also responsible for clotting of blood, collapse of a bridge and nuclear explosions.

Have a day filled with positive feedback.

The Bible. Why you should read your Bible.

After reading what The Candid Tin man had to say about the Bible on his blog, I felt a disappointed man. In my opinion, the candid Tin man had committed the same errors of omission and commission that have plagued the Bible for centuries.

In the beginning, the Roman Catholic church was the dominant church worldwide, and the bible existed in Latin language which common folk like me and you did not understand. Latin was a dead language used by the priests of the roman Catholic church and perhaps a few scholars.

The Roman Catholic church aimed at controlling the public's opinion , as the church still does today, and especially their opinion of what was God's word. Therefore, back then, if you needed to understand God's word, you had to consult the Roman Catholic Priests to read the Bible for youa nd then tell you what it said. How well they did this and their intentions remained questionable, with accusations directed at the Roman Catholic Church for mistranslating The Bible…

The bitter story of the downfall of Mumias Sugar company

Have you heard the bitter story of Mumias Sugar?

Regarded by many as Kenya's most successful sugar miller, Mumias Sugar Company was a disaster waiting to happen.

Many pointed out how Mumias Sugar Company was a fortress in the wreck that is Kenya's sugar industry, only unaware that it was just a matter of time. As the old wise men said, "Ukiona cha mwenzako cha nyolewa, tia chako maji".

The proverb means that if you see your neighbour's head getting shaved, your head will soon be undergoing the same - you'd therefore better wet your head for a smoother shave, otherwise you will be forced to undergo a painful, dry, shave.

But what ails Kenya's sugar industry?

The Kenya sugar industry is under legal siege. The typical Kenyan issue of coming up with laws to tackle a problem is evident here.

Many of Kenya's sugar factories are owned by the government, and have slowly declined under mismanagement and corruption. The appointing of political cronies and trib…

The Idle Life of a Regular Kenyatta University Student.

My education life was quite an active one, till I completed the 8.4. part of 8.4.4. I went to good primary schools, with tuition in class 6-8 and boarding in class 7 & 8. My life in primary was quite full, esp with tuition in class 7 & 8.I passed KCPE and was admitted to a good National School in Nairobi. My High School life was divided into 3 months holiday and 9 months schooling per year, except for 4th form where i spend I had a 1 month holiday between January and November. I was therefore well occupied for the first 12 years of my education.

After sitting for my Kenya Certificate of Secondary Education(KCSE) in November 2004, I had to wait for results till March 2005. I was well above the B+ university cut off. Previously in early 2004, we had chosen universities and courses we would like to attend by filling the Joint Admissions Board forms. After the results were out in early 2005, we had to wait till August 2005 for the 2004 KCSE lot to change their university and cours…

Beers in Kenya: A sober opinion

Note: This is a dated post and has since been mostly passed by events. SAB Miller beers including Castle and Peroni are no longer widely available in Kenya after their exist. Sirville Brewery was bought out by Brew Bistro before being permanently shut in a tax dispute. Kenya is a land of milk, honey, beaches and taxes. I have penned, or is typed, a newer post here

I have had a short beer swigging stint in my life. It has however been long enough for me to share my opinion of Kenyan beer. Interestingly, over the course of sharing such opinions with other drunkards connoisseurs,  I have found that we all have different views as to what beer is the best, which one makes you too drunk, or which one gives one free, extra hangover for every hangover you get from it.
For starters, like everyone else, I discovered that beer isn’t as sweet as it looks like in those adverts that show golden barley swaying in breezes, happy men smiling and toasting chilled, foaming glasses of beer as a deep voi…

Why I plan to Enroll in a School that teaches me how to spend money

So yesterday it was raining, and rain it did. Matter of fact, it rained so hard that some people believed that the rain was more than just a matter of cats and dogs. Even cats and dogs were scared of venturing out in this rain that reportedly led to the loss of many shoes (and those sandals that girls in Nairobi call shoes)

As it happens in Nairobi, rain is one of the few things that outdoes the presidential motorcade when it comes to bringing Nairobi traffic to a stand still. Despite having universities in every province and every city and soon in every top 10 community, we are yet to conduct research on what drops of water have to do with vehicles moving on a road.

As such, with traffic coming to a stand still, matatus are caught up and therefore the matatu stages become void of matatus and full of passenegers wanting to get home away from the rain. some of them even take the initiative to walk out of town and meet the matatus. At the same time, matatus increase the fare for reasons…
