Haskell shell scripting!

Posted 10-25-2012 at 11:19 AM by hydraMax (Bits and Pixels)

Practical shell scripting AND full-fledged Haskell functional programming at the same time!? Is it really possible to have your cake and eat it too!? I'm sweating with excitement at my recent discovery.

Not only is it possible, but there is a well-developed module that allows you to do shell like programming with Haskell, without losing any of the benefits of the language:

Bash quickie: loop N times, without doing math

Posted 10-22-2012 at 09:07 PM by the dsc (linux-related notes)

Tags bash, loop

I thought that the only way to do such type of loop in Bash would require something like "n=$(($n+1))" within the loop, with the loop being conditioned to "n" adding up to whatever you want, such as "until ((n==30)) ; do". But you can actually do "for i in {1..20} ; do <whatever> ; done". That's somewhat similar to Basic's "for i=1 to 20 ; whatever ; next i".

But it won't work with variables for the starting and ending numbers....

One of the aspects about Linux that I love and sometimes hate, is the ever present opportunity to learn something new. Recently, Linux has seemed to me like a much admired friend, that routinely surprises you with some cool and new thing to be admired I've worked exclusively with Linux as my PC of choice for about 5 years, and am currently running Slackware-14 64 bit. I can honestly say, that from the very beginning, not a month has passed where I haven't learned at least one new facet of Linux....

The Lost Art of Situational Awareness

Posted 10-21-2012 at 07:39 PM by rocket357 (Musings on technology, philosophy, and life in the corporate world)

I was driving to the store tonight. As I drove through the (seemingly) deserted stretch of parking lot, I came up to a man, woman, and child walking through the dimly lit area. I noticed that they were uncomfortably close to the road, so I started to fade to the left to avoid them. As I approached, the man continued narrowing the gap between my 2 1/2 ton vehicle and his body. His wife wisely stayed to the right with their child...but then an amazing thing happened...

I continued...
