Fiddling with HTML and JavaScript, I know that `createElement()' should be used to create a new HTML element, and it is only possible to do so with XHTML documents. So, I was surprised when I found out that I can do `new Option([text[, value[, defaultSelected[, selected]]]])' to create a new HTML Option element to be added to an HTML Select element. The next question that followed will be: who standardizes the arguments to the constructor of an HTML Option element.

When studying computer networking, the term logical networking stack is often heard.
The most famous example will be ISO OSI's logical networking stack that consists of seven layers, which are:
- Application,
- Presentation,
- Session,
- Transport,
- Network,
- Datalink, and
- Physical.

For those facts, I have the following questions:
1. What is the purpose of having a logical networking stack at the first place?
2. Why does ISO OSI's consist of seven layers instead of three or ten?

कुंभारासारखा गुरू नाही रे जगात
वरि घालितो धपाटा, आत आधाराला हात

आधी तुडवी तुडवी मग हाते कुरवाळी
ओल्या मातीच्या गोळ्याला येई आकृती वेगळी
घट जाती थोराघरी, घट जाती राऊळात

कुणी चढून बसतो गावगौरीच्या मस्तकी
कुणी मद्यपात्र होतो रावराजांच्या हस्तकी
आव्यातली आग नाही पुन्हा आठवत

कुणी पुजेचा कलश, कुणी गोरसाचा माठ
देता आकार गुरूने ज्याची त्याला लाभे वाट
घट पावती प्रतिष्ठा गुरू राहतो अज्ञात

- ग. दि. माडगूळकर

Previously, I wondered why the need of XHTML specification by W3C. Now after I was cluttering my hands with ECMA Script (i.e., JavaScript) for a while, I found the definite reason.

Back when I was in the last half part of my third semester of my undergraduate study, there was a fever among my classmates to solve Sudoku puzzles. I just tried to scratch some of those puzzles but find them not exciting because I only need to employ a trial-and-error method. Later, in the beginning of my fourth semester, I tried to find an algorithm to solve those puzzles and ended up with a method that I will describe here.

Brought Belkin Wireless G USB Adapter this week. My home ubuntu 8.10 recognised it and networked without any additional settings besides wireless security. Just to let you know.

A CEO from my previous organisation mentioned something to me that he had experienced in the dot com bubble burst. He was a CEO then too. "Running a company, is a lot of responsiblity. As the company grows, so does the dependency of a lot of families and their economies on the company. A mistake you make does not only affect you but the families of all your employees. And that is 'responsibility'."

As the global economies are spiralling down, companies are being conservative.

If you can't live without amputing your arm, left without an option, you'll opt to do so.

I remember when we had to hire a couple of freshers in one of the really small startups I was working for. While I did that, the first thing in my mind was to hope that the company stays around for at
least 1 year, since that is a sizable experience for the freshers to start their career with. And I made them fully aware of the fact too, since like all freshers, they had multiple options to consider.

I understand that running a business means you have to take hard decisions. And hard decisions are bitter. If worst comes to worst, of course, you have no option but to trim down. But "hard decisions" or
"business decisions" are certainly not the way to shrug away from the responsibility. A workforce cut is a particularly bitter experience. But there are ways in which you can alleviate that.

The relationship between employer and employee is mutual. If you treat them as family, they treat you as a family and the whole thing is good for you, your employees, your product and your customers. (I am not
exaggerating, there are companies that go out of their way to ensure that their strongest asset, the employees, are comfortable.) And the way you trim down tells a lot about your character and that of your
company. It shows whether you treat your employees as family, or as cattle. And if it is the latter that gets revealed, well, all those employees who have fortunately saved their asses this time around, take a warning cue from the event and do the neeful.

I needed to recompile my code to test it against UML but it always complained about the unlock_kernel() function. The original code comes from subversity.net

So I decided to slightly modify the code to make it works for UML and x86. I did not have the chance to test it for other architectures.

data E a b = L (E a b) | R b deriving (Show)

fold f acc [] = R acc                      
fold f acc (x:xs) = let x' = f acc x 
                    in x' `seq` (L $ fold f x' xs)

lift2 f = \x y -> par_eval x y
    where par_eval   (L x)   (L y) = par_eval x y
          par_eval x@(R _)   (L y) = par_eval x y
          par_eval   (L x) y@(R _) = par_eval x y
          par_eval   (R x)   (R y) = R $ f x y

lift1 f (L x) = lift1 f x
lift1 f (R x) = R (f x)

len' xs = fold (\x y->succ x) 0 xs
avg  xs =  (sum' xs) / (len' xs)

Hi,

I have upgraded the kernel 2.6.9-55.0.12.ELsmp to 2.6.9-78.ELsmp.
After upgrading i got the following Error in message logs.Then i rebooted the server.now it is working. But i want to know why was the kernel panic and can it happen again;

kernel: kernel BUG at kernel/exit.c:904!

LSE - Linux Security Engine

LSE is an open source security project for GNU/Linux (Kernel 2.6 series).

It employs a "white list" approach to allow/disallow program execution on your computer.
It's an easy way to prevent user running applications which can be malicious [virus, backdoor, rootkit, ...] or simply unwanted.

Hi All,

I am using linux-2.6.25-rc7 distribution,U-boot-v2 bootloader and IMX27ADS target.I built uboot.bin from U-boot-v2 and it is working fine on IMX27ADS.
I want to boot linux kernel image on IMX27ADS.

A friend of mine would like to try to implement a new system call based on the example in Chapter 8 of Linux Kernel Module Programming Guide 2.6 Series (http://www.dirac.org/linux/writing/lkmpg/2.6/lkmpg-2.6.0.html) in Linux kernel 2.6.21.5. The example requires that the kernel exports `sys_call_table' symbol. Although Linux kernel 2.4.x, on which the guide is based, still exposes that symbol, Linux kernel 2.6.x does not do that anymore for it is harmful (e.g., it is unimaginable if a module replace the system call of `link' with `unlink' via the table). The guide comes with a patch to expose the table in Linux kernel 2.6.x. However, the patch does not work in particular for Linux kernel 2.6.21.5. So, I helped him to do so.
