Programming :: Write A Kernel In A High Level Language Such As Python?

Apr 27, 2010

Most kernels are written in low level programming languages such as C and Assembly. Would it be possible to write a kernel in a high level language such as Python? Many high-level languages are themselves written in C.

Programming :: What Language Would You Write A Social Networking Site In?

Jan 8, 2010

I'm a full-time developer in my day-job, I get paid real money for it and everything! Nowadays I generally write web-based business apps using and, but I'v recently been asked to come up with a social networking type site (something in-between Facebook and twitter) that will initially be used for training purposes... don't ask or I'll have to send the men in the dodgie overcoats round

Problem is, it is to be written like real social-networking site, I've no idea what I'm going to make it look like and was, more fundamentally, wondering what to write it in?I've written commercial systems using Perl, PHP, ASP and the .net (VB and C) stuff.

Programming :: Accessing And Performing Operations On Base Level Kernel Structure?

Jan 20, 2011

We all know linux kernel base layer is made up of structures, in which every object of kernel is well defined. Structure members correspond to object properties required to define object behavior.

For example if we take case of File system.It composed of four objects , superblock objects, inode objects, file objects and dentry object.Each having well defined structure which is being operated by system call handler and by system call service routine in the kernel mode.

Now my question is even in kernel mode we do not have some mechanism by which we can get access to pointer of these structures.We have some macro.

If I want to manipulate structure on my on way, or performing some more operation defined by me.For example after the crash of Hard Disk Drive, having ext2/3 file system, If i want to know all the inode pointers, and block details.

Can I have some way out to do desired operation ??

mechanism to operate on these base label structures, even in kernel mode ..

Ubuntu :: No High Level Format For LS-120?

Nov 29, 2010

I'm running 10.10, but this seems to be an ongoing problem. While every other OS on the planet seems to be able to high level format LS-120 super floppies in their IDE drive, Linux can't. DR DOS can. OS/2 can. Windows 98 forward can.

We aren't talking low level format here. We are talking "quick" format where a new FAT and label are written to the media along with the high level markings/surface scan.

I can load a disk, copy to it, delete from it, but cannot perform a high level format.

General :: High Level Command Line Program For Burning CDs And DVDs?

Mar 12, 2010

I'm sick of screwing around trying to script a clean solution to burn multiple files and folders to CDs and DVDs with wodim, growisofs and genisoimage.I'm looking for a high level command line program that uses sensible defaults and takes arguments something like this:[program-name] [cd|dvd] /path/to/dir1/ /path/to/dir2/ /path/to/file ...It should then do all the low level copying and ISO generation transparently and just burn the damn disk!Does anyone have any suggestions? I've looked at several programs but it seems there are too many choices to trawl through and not enough information about them online.

Slackware :: Disabling High Intensity At The Video Card Level (text Mode)?

Jun 17, 2011

Kernel, slackware 12.0

When you do 'man bash', you'll see some words are highlighted. I'll say that the video card has used high intesity in these instances. How do I disable this video card capability? Can this only be done by recompiling the kernel? Of course, I am talking about the text consoles, i.e., the video card in text mode.

Debian Configuration :: Kernel Panic: Power/level Is Deprecated?

Jul 13, 2011

I am currently having issues with system freeze when unmounting portable hard drives. This happens almost every single time. Normal USB sticks are fine and do not produce the freeze. I am using kernel 3.0.0-rc6, however the issue also persists when switching back to 2.6.39. This is the error message i get when freeze occurs, reverting to terminal output:

WARNING! power/level is deprecated use power/control instead

General :: 1:1 - What's Meant By There Is Kernel Level Thread For Each Pthread Created

Mar 11, 2011

I have gone thorugh some documents about pthread (NTPL ) in linux 2.6 kernel. As per that linux uses 1: 1 threading model and for each user level thread there is kernel level thread. Pthread_create uses clone system call to create a LWP and the kernel could treat that as a LWP and do scheduling and all .( different from linuxthread). My question is what's meant by there is kernel level thread for each pthread created. Can I see the kernel level thread if I call pthread_create using ps .

What exactly meant by 1:1 .I mean for each user level thread there is kernel level thread . If I make a system call from a thread does the OS services that action via kernel thread ( created using kernel_thread () or some other way ) internally ..
