Top Five Regrets of the Dying

Beautiful article. Very profound. Here

This snippet resonates with my beliefs –
They had stayed stuck in old patterns and habits. The so-called ‘comfort’ of familiarity overflowed into their emotions, as well as their physical lives. Fear of change had them pretending to others, and to their selves, that they were content. When deep within, they longed to laugh properly and have silliness in their life again.

Halo effect and other cognitive biases

List of cognitive biases

I was reading about the “halo effect” that the iPod has had over the entire apple portfolio. Hit upon this comprehensive list of common cognitive biases…

Now, that you understand biases – over to fallacies!

https://en.wikipedia.org/wiki/List_of_fallacies

 

A false dilemma, is a logical fallacy which involves presenting two opposing views, options or outcomes in such a way that they seem to be the only possibilities: that is, if one is true, the other must be false, or, more typically, if you do not accept one then the othermust be accepted. The reality in most cases is that there are many in-between or other alternative options, not just two mutually exclusive ones.

Always fascinated by fancy terms… 🙂

Amazon EC2 and S3 – Amazon Cloud service

Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides resizable compute capacity in the cloud. It is designed to make web-scale computing easier for developers.

Amazon EC2’s simple web service interface allows you to obtain and configure capacity with minimal friction. It provides you with complete control of your computing resources and lets you run on Amazon’s proven computing environment. Amazon EC2 reduces the time required to obtain and boot new server instances to minutes, allowing you to quickly scale capacity, both up and down, as your computing requirements change. Amazon EC2 changes the economics of computing by allowing you to pay only for capacity that you actually use. Amazon EC2 provides developers the tools to build failure resilient applications and isolate themselves from common failure scenarios.

Amazon S3 is storage for the Internet. It is designed to make web-scale computing easier for developers.

Amazon S3 provides a simple web services interface that can be used to store and retrieve any amount of data, at any time, from anywhere on the web. It gives any developer access to the same highly scalable, reliable, secure, fast, inexpensive infrastructure that Amazon uses to run its own global network of web sites. The service aims to maximize benefits of scale and to pass those benefits on to developers.

Searching for commands on Unix

Sometimes when you forget the exact command on unix but know what its supposed to do, you can use the nice “search” feature that’s built into “man”.

man-k

it searches all the man pages on the machine and retrieves the commands for you!

Example:
man –k memory
Gives you all the commands that have to do with memory…

apropos is a wrapper for man –k. so you can use that too.
