Raw Thoughts ,Technology, Experiences

Its been early days for me with LISP. A great deal of time went in searching the tools like tutorial , IDE , LISP compiler etc (its indeed a confusion to choose). finally everything is settled down , guess which editor is chosen for LISP? its Eclipse, the CUSP plugin is great though the lisp purists argue that emacs or slime is the ideal one. I feel eclipse + cusp = great LISP environment.

As for as tutorials for LISP is concerned SICP is the best but i feel the Apress publications Practical Common LISP is some thing which i can digest. I have been using the LISPBOX which is tailor made for the newbie like me. Its just simple download , decompress and launch the SLIME else install the CUSP (be sure to choose the CLISP of LISPBOX instead of SBCL which is a default LISP for CUSP plugin). And there you are up and running your LISP environment.

LISP is extremely interesting. I initially had an idea like its only meant for stuff like AI, or some mathematical computing, but i was thrilled to learn that its not the case. You can use LISP to develop some webapplication as well. it has a persistance called Elephant and the web server called Hachentoot.

LISP is really cool and i am sure i shall get use to it in some time. do check this section for more updates.

Yes, I am alive.. its been long time since i blogged. This post is kinda to say that i am alive I have been playing around with groovy,Common LISP. I feel Common LISP is one language to learn properly. will be back in near future with my experiences with LISP and Groovy…..

There is an hands on Lab kinda session on Design Patterns. So dont forget to get your Laptops.

I just went through this article from one of the blogs, which says like Ubuntu will have HDD in trouble when your laptop is running on the battery. The reason is that, the disk heads are parked as part of the power saving strategy. When the disk needs to be accessed, the heads are unparked.This can only happen about 600000 times before a disk becomes likely to fail :p.

Its been found that “Feisty and Gusty releases of Ubuntu do this up to 4 times per minute, which is _bad_, considering that kind of frequency gives your hard disk a life expectancy of 104 days! ” it seems , which is really an alarming issue to the Ubuntu team.

All said and done , now whats the solution? The solution is to turn off this power management issue by executing the following commands.

” sudo hdparm -B 255 /dev/sda ” :- to turn off the power management.

“sudo smartctl -d ata -a /dev/sda | grep Load_Cycle_Count” :- to check life left in your hard disk :p

I hope that ubuntu team team take this issues seriously before it looses its faithful users.
