Front Tine Versus Rear Tine RotoTillers - An Engineer Explains Which RotoTiller is the Best and Why
If you're considering buying a roto-tiller, you probably already know that there are two basic types -- the rear-tine tillers and the front-tine tillers.
What's the difference and which rototiller is the best for you and your garden?
An engineer reveals the facts every gardener should know.
As the name implies, the front-tine tillers have the tines in front of the wheels and under the engine. Likewise, the rear-tine tillers are located behind the wheels.
Basically the rear-tine tillers are best for large areas or for hard clay soils. Also, the rear-tine models don't work you as hard and don't beat you to death, but they are usually more expensive.
On the other hand, the front-tine models are great for small gardens and for soft soils. Of course, any garden can be made to have reasonably soft soil IF you work enough manure and other organic matter into the soil.
For years I've used both the small, front-tine mini cultivator types and the larger, heaver (and more powerful) front-tine roto tiller. Overall, I like the more powerful models. It allows me to work faster, work in harder soil. But let me warn you, the larger models will work you like a mule.
The rear-tine rototiller models don't work you nearly as much, but as I said, they are more expensive. I love to use the rear-tine roto-tillers, but I don't like the price tag.
My conclusion: To get the most bang for your buck, spend the extra money on getting more horsepower in a front-tine model rather than buying one of the rear-tine tillers --unless you are a petite woman or are working a small garden or flowerbed.

Social Engineering and Social Networks
Social Engineering, for those who probably are not aware of, refers to a method of divulging confidential information from people through non-technical means that will allow unauthorized access to a valued system and the information that resides on that. In a few words, this is an attack that normally serves hackers to gain access to enterprise networks or to target individuals, depending on the purpose of the attack.
The purpose of this article is to highlight the importance of privacy security on the Internet and how this is related with social engineering. An example of social engineering attack involves the attacker, the victim and the information retrieval. Imagine that you post on Facebook some destinations and places that you have visited and you have described them with enthusiasm. An attacker could exploit this information so as to call you up (find your number in a catalog or even from Facebook or send an e-mail). Then the attacker asks you to give your personal information, with the excuse that you've won a money price from a lottery, made for a Hotel's customers, in which you had stayed as long as you were visiting the places you describe in your profile. Probably you might trust him and give him information about you, even your social security number or possibly your bank account. The next step is to call your bank and pretend to be you, claiming that your online account was blocked and you will need a new password. The data that the bank will require are already in attacker's disposal and the request can go on. This is an easy way to lose money and not be aware of the fact at all, at least not in the beginning.
It is one of many examples, which occur in everyday life, but most of us don't know the dangers that exist, while overexposing so many personal data. Even bigger is the risk for companies, especially if we think the increasing use of LinkedIn, which is a social network designed exclusively for professionals. Many users publish their CV and often share it with people they have never met. There are many ways an attacker can exploit such information and they can lead to a breach a company's infrastructure and jeopardize sensitive data and business continuity.

Importance of Engineering to the World
If you walk around the streets and wonder a little about how amazing the structures and vehicles around you, you should be thankful to the thing called engineering. Believe it or not, there are many importance of engineering to the world, and here are some of them.
The first point is that engineers are given the role to create systems that are able to protect and unite the people and the environment around them. The tricky part is that this should not be done haphazardly, but with detailed planning to ensure that the system works and is sustainable, yet is not uncomfortable to live in.
Another important point of the role of an engineer is that they are educated to work with cost, time, and even the wellness of people throughout their constructions. They will need to be able to build structures that not only last, but also to ensure that it is safe and comfortable for people to use.
Apart from that, with engineers around, we do not need to live in our own dumps and wastage. Imagine taking a dump in a toilet bowl that only sat at the bottom of the land because no one had come up with an efficient toilet to sewage and plumbing system - the area would smell terrible! Hence, engineers help analyze and design ideas that allow us to live in a better and hygienic place, which also goes back to the point of safety.
The ones who created the roads are the engineers; connecting one civilization to another. It brings people closer together, like a bridge over a river. If people can live alone without companions, it might not be a problem. But in fact, no man is an island. We are kept up-to-date and are able to interact with other people because of the existence of technology in which engineers have contributed to our lives. The distance from Point A to Point B is cut short because of such contributions.
If you are interested in filling up this important role in the future, you can start by completing an Engineering degree from an accredited school. With an Engineering degree, you will meet the minimal requirements to be qualified in this field.

Where Are the Engineering Jobs?
The engineering professions have been hard hit by the recession; especially Civil Engineering. You have probably noticed that there are not many job postings for engineers. In small pockets of the country are starting to seek out your expertise.
Researching some of the top engineering job posting sites on the internet, one can quickly see that the number of job postings has been drastically reduced compared to several years ago. Many States like my home State of Nevada job postings for engineers are few, while other States like California and Texas there are quite a few more.
Which of the 5 geographical areas in the United would fair better; Northwest, Mid-west, Northeast, Southeast, or Southwest? In order to answer this question, we decided to look at several of the main online job listing sites, and categorize the listings as follows: the number of civil engineering job postings, number jobs in geographical areas, and the states with the highest number of job postings.
After reviewing several sites a pattern emerged that was a little surprising. The initial results showed that the number of listings were extremely low. States with zero or extremely low number of listings were Rhode Island and South Dakota. Several States would only show one or two listings like Delaware, Kentucky, North Dakota, and West Virginia.
The southwest region in every website we visited had the highest number of postings. In each analysis California's and Texas's high job postings carried the southwest region to the lead.
1. Southwest Region - All of the websites surveyed showed that this region had the highest number of job postings for Civil Engineers. The job postings in California and Texas were about seventy percent of the region's total number.
2. Southeast Region - The number of job postings were not far behind the southwest region. The number of job postings seemed to be a little more spread across the States in this region. Florida, Virginia, and Washington DC area typically had the highest number of postings.
3. Northeast Region - The states of New Jersey, Maryland, New York, and Pennsylvania typical had the highest number of posts in this region, but Rhode Island and Vermont were usually the lowest.
4. Mid West Region - This region consist of the most States, but had very low job listing numbers for each State. The exceptions were Illinois and Ohio with about 50% of the postings combined.
5. Northwest Region - This region showed the lowest number of job postings on all of the websites we reviewed. With about 70% of the available positions the State of Washington had the highest number of postings in this region.
It should be noted that the States with the highest listing were also States with large populations. In that sense the higher listings is right in line with what would be expected. If the numbers were adjusted with taking into account the State's population a different result have occurred. At any rate the overall numbers were very low. The site with the largest number of listings for Civil Engineers only had 1,147 posts.
Another result that we like to analyze is how many Civil Engineers are unemployed right now. The same type of analysis can be preformed by looking at how many engineers are unemployed in each state, and region. Perhaps in a future article we can address this matter.
What can you take away from this survey mean? The country is still trying to recover from the recession, and from what we can gather from our review many engineering companies are not hiring. California, Florida, Maryland, New York, New Jersey, Pennsylvania, Texas or the Washington DC area are probably the best areas right now to find employment. Due to the low job posting numbers on the websites, obtaining employment in any other State would be extremely difficult.
