100% uptime claims considered harmful.

"Of course, 100% uptime is a good goal to aim at, as long as everyone realizes that it is impossible to achieve."

Learn Python in 10 minutes

"So, you want to learn the Python programming language but can't find a concise and yet full-featured tutorial. This tutorial will attempt to teach you Python in 10 minutes. It's probably not so much a tutorial as it is a cross between a tutorial and a cheatsheet, so it will just show you some basic concepts to start you off."

How do I… Build and configure an external hard drive enclosure?

"Do you have an old hard drive, which still works, lying around and gathering dust that you’d like to put to good use? If you answered yes, then chances are good that you’ve thought about using your old drive as an external hard drive. Fortunately, building an external hard drive is an easy task. Since you already have the hard drive, all you need is an enclosure, a screw driver, and less than an hour of your time. Let’s take a look."

Reaction to the DEC Spam of 1978

"Possibly the first spam ever was a message from a DEC marketing rep to every Arpanet address on the west coast, or at least the attempt at that."

"The sender is identified as Gary Thuerk, an aggressive DEC marketer who thought Arpanet users would find it cool that DEC had integrated Arpanet protocol support directly into the new DEC-20 and TOPS-20 OS."

"

The Art of Unix Programming

"You should read this book if you are an experienced Unix programmer who is often in the position of either educating novice programmers or debating partisans of other operating systems, and you find it hard to articulate the benefits of the Unix approach.

You should read this book if you are a C, C++, or Java programmer with experience on other operating systems and you are about to start a Unix-based project.

You should read this book if you are a Unix user with novice-level up to middle-level skills in the operating system, but little development experience, and want to learn how to design software effectively under Unix.

You should read this book if you are a non-Unix programmer who has figured out that the Unix tradition might have something to teach you. We believe you're right, and that the Unix philosophy can be exported to other operating systems. So we will pay more attention to non-Unix environments (especially Microsoft operating systems) than is usual in a Unix book; and when tools and case studies are portable, we say so.

You should read this book if you are an application architect considering platforms or implementation strategies for a major general-market or vertical application. It will help you understand the strengths of Unix as a development platform, and of the Unix tradition of open source as a development method."

MVC - Model, View, Controller

"The essential purpose of MVC is to bridge the gap between the human user's mental model and the digital model that exists in the computer. The ideal MVC solution supports the user illusion of seeing and manipulating the domain information directly. The structure is useful if the user needs to see the same model element simultaneously in different contexts and/or from different viewpoints."

Bringing Back the Hat

"Hats are both functional and stylish. They can cover a bad hair day, keep your head warm, and shade your eyes from the sun. They can also be worn to cover a receding hairline, which interestingly enough is why Frank Sinatra, an iconic hat wearer, start wearing one in the first place. They give you touch of class and sophistication, impart personality, and add an interesting and unique accent to your outfits. And hats are a sure-fire way to boost your confidence. A cool hat can quickly become your signature piece and give you extra swagger."

Walking Hats created by Wicked Worm Ltd

"The two peaks are set at different angles from the crown. Whilst the front peak cuts the glare and protects the face from the weather like a baseball cap, the rear peak protects the back of the neck from sunburn – and from rain running down the neck and inside the waterproofs. A breathable inner elasticated band keeps the waterproof walkers’ hat firmly on the head even in the windiest of conditions. You get maximum protection from the elements and complete freedom of movement. This is the hat for the long walk; it’s both functional and flattering! It can pack away easily in a rucksack or jacket pocket. It is an essential accessory for every walker."

Yoga Natural: La Gran Relajación

"De ese modo, cuando pasamos por alto la verdadera naturaleza de los pensamientos, los encadenamos entre sí pero, en el momento en que reconocemos que el pensamiento está vacío de existencia independiente y que sólo es la conjunción de diversos factores, entonces, le quitamos todo su poder y ya no lo encadenamos ni lo relacionamos con el siguiente pensamiento. Esto, sin embargo, no significa que haya que detener el pensamiento de manera deliberada utilizando alguna técnica artificial, sino que basta con reconocer la naturaleza de los pensamientos y permanecer con una mente relajada, despierta y estable."

http://yoganatural.blogspot.com/

" Thus, when we ignore the true nature of the thoughts, chained to one another but, at the time that we recognize that the thought is empty of independent existence and that it is only a combination of various factors, then you remove all its power and no longer chained or what relate to the following thought. Esto, sin embargo, no significa que haya que detener el pensamiento de manera deliberada utilizando alguna técnica artificial, sino que basta con reconocer la naturaleza de los pensamientos y permanecer con una mente relajada, despierta y estable. This, however, does not mean stopping the thought of using any technique deliberately artificial, but simply recognize the nature of the thoughts and stay with a relaxed mind, awake and stable. "
