Let me ask you a question, if the odds are against you already in a self-defense attack, why would you aggravate things more by increasing your disadvantage? I mean, you’d have to be nuts to hurt yourself, and help your attacker – to be an accomplice to your own ass-kicking… right?
This article is about avoiding doing just that. In it, I share with you the number one reason why I avoid teaching my students to use a standard clenched fist when striking your assailant’s face in a self-defense street attack. And, I’m going to give you 4 strikes that are much better for getting the results you want, without the same risk of damage in the process!
But first, let me share with you the number one reason that you’d have to be crazy to punch someone in the face with a clenched fist.
Because you’ll probably damage your own hand in the process.
Don’t believe me? How can this be so? After all, isn’t that what everyone does?
For the most part, the answer is “Yes.” But, at what price?
Look at the boxers and other fighters who get into fights outside of the ring. Do you know what happens, even if they win? What happens is that most of them…
End up with broken hands, fingers, or wrists in the process.
Not very smart.
And the reason that this happens is because it’s almost impossible to punch a human being in the face without making impact with the chisel-like “processes” or ridges on the frontal, facial, part of the skull. In fact, it’s impossible to punch someone in the face with a standard clenched fist – from the eye brow ridge down to the jaw, and from the edge of the eyes across the face to each side – without making contact with one of these chisel-like ridges.
So, now what?
The “now what” is…
What if I could show you how to punch an assailant in the face – to get the same kind of mind-rocking effect that only a head-shot gives you (more in fact) – without risking the breaking of your hand, fingers, or wrist in the process?
Would you be interested?
Somehow, I knew you would.
So, instead of trying to figure out how to hit someone with the same “caveman-style” punch that everyone else is using – regardless of the consequences – let’s look at 4 alternate “fists” that will do more with less energy…
AND… that will not trade off a broken hand for whatever damage you do manage to get in the process.
* 1) Palm-heel strike – By using the base of the palm – the solid part of the palm that is in alignment with the firearm bones, you get the battering-ram like power without the need to worry about your wrist folding, or breaking the smaller bones of your fingers when they collide with the facial bones. In fact, like most of the fists that I’m sharing with you today, it actually fits right in-between the problem areas that I am constantly warning my students about!
* 2) Thumb-drive strike – The tip of the thumb can deliver amazing power and damage to the thinner bones in front of the sinus cavities, as well as everywhere else on the face. By making a standard fist, and then pressing the middle joint of the thumb down on top of the folded index finger, you know have the capability of taking the power generated by the mass of the larger clenched fist, and concentrating it into a much smaller point.
* 3) Knife-hand strike – Also know conventionally as the “karate chop” or “judo-chop,” the knife-hand strike concentrates the striking force along the outer-edge of the palm. Again, just like the palm-heel strike, the narrow nature of this “fist” allows it to slip easily between and into the bone surfaces behind the face that everyone else focuses on.
* 4) Forearm strike – What most people think of as a tool merely for blocking, the real self-defense expert sees as a clubbing weapon. The forearm – especially the ulnar bone (the bone on the outside edge of the forearm) – can cause even the most determined attacker to drop in his tracks.
Each of these strikes is unconventional to say the least. But, that’s the point of training, isn’t it – to develop stronger, more accurate, and better techniques, tactics, and strategies that will allow you to be the winner?
Of course it is.
Just remember that fighting, even self-defense, holds the risk that you could be severely damaged. But, your training should not cause you to hurt yourself! And, especially when it comes to defending yourself, the idea is to “fight smarter – not harder!” SABUNG AYAM
Facebook’s new energy efficient data center
Cloud technologies power some of Internet’s most well-known sites—Picasa, Gmail, Facebook and Zynga, just to name a few—and cloud companies are striving to make the computer processing behind these sites as energy efficient as possible. With that in mind, Facebook, Dell, HP, Rackspace, Skype, Zynga and others have teamed together to form the Open Compute Project to share best practices for making more energy efficient and economical data centers.
To kick-start the project, Facebook unveiled its innovative new data center and contributed the specifications and designs to Open Compute. “Cloud companies are working hard to become more and more energy efficient…[and] this is a big step forward today in having computing be more and more green,” explains Graham Weston, Chairman of Rackspace.
A small team of Facebook engineers has been working on the project for two years. They custom designed the software, servers and data center from the ground up.
One of the most significant features of the facility was that Facebook eliminated the centralized UPS system found in most data centers. “In a typical data center, you’re taking utility voltage, you’re transforming it, you’re bringing it into the data center and you’re distributing it to your servers,” explains Tom Furlong, Director of Site Operations at Facebook. “There are some intermediary steps there with a UPS system and with energy transformations that occur that cost you money and energy—between about 11% and 17%. In our case, you do the same thing from the utility, but you distribute it straight to the rack, and you do not have that energy transformation at a UPS or at a PDU level. You get very efficient energy to the actual server. The server itself is then taking that energy and making useful work out of it.”
To regulate temperature in the facility, Facebook utilizes an evaporative cooling system. Outside air comes into the facility through a set of dampers and proceeds into a succession of stages where the air is mixed, filtered and cooled before being sent down into the data center itself.
“The system is always looking at [the conditions] coming in”, says Furlong, “and then it’s trying to decide, ‘what is it that I want to present to the servers? Do I need to add moisture to [the air]? How much of the warm air do I add back into it?'” The upper temperature threshold for the center is set for 80.6 degrees Fahrenheit, but it will likely be raised to 85 degrees, as the servers have proven capable of tolerating higher temperatures than had originally been thought.
The servers used in the data center are unique as well. They are “vanity free”—no extra plastic and significantly fewer parts than traditional servers. And, by thoughtful placing of the memory, CPU and other parts, they are engineered to be easier to cool.
Now that these plans and specifications have been released as part of the Open Compute Project, the goal is for other companies to benefit from and contribute to them. “Open source, crowd sourcing, Wikipedia—these are all capitalizing on, or enabled by, the same force,” explains Weston, “which is that when things are open, there’s more innovation around them.”
