Programming :: Reverse Bit Order In MIPS/SPIM?
Apr 27, 2009
Here is what I have so far.The program receives and echos characters without syscalls. I am trying to add 2 procedures(rev7 and putint)Rev7: Reverses the least significant 7 bits and outputs $s2Putint: Prints the decimal value of $s2.When i run it, it echos the character then prints a "P". I have no idea where that comes from.Everything seems correct to me but I do not understand why it does not print the decimal digits
Code:
.data
hello:.asciiz "Enjoy This Program

I'm trying to write an extension to PHP which means coding in C. I'm really really rusty at C coding and was never very good at it.
Can anyone propose an efficient, safe, and [hopefully] future-proof way of reversing a double? Keep in mind that it should work on as many systems as possible and on 32- and 64-bit systems (and on ???-bit systems in the future?). Will the size of a 'double' ever change or will it always be 8 bytes?
I've tried this and it doesn't work...the compiler complains about "invalid operands to binary" because I'm trying bitwise shiftw on a non-integer.
Code:
x = (x>>56) |
((x<<40) & 0x00FF000000000000) |
((x<<24) & 0x0000FF0000000000) |
((x<<8) & 0x000000FF00000000) |

I'm curious as to whether anyone else has experienced this, and has an explanation. I'm running Kile 2.0.85 under openSUSE 11.3 32-bit on a Lenovo X61. Twice in the past couple of days I've had the bizarre experience that, upon a sudden burst of typing my text has appeared in Kile in reverse order.
no ngis fo ecnacifingis eht fo redaer eht dnimer esaelp ,dniw cihportsoeG a htiw snoitalumis eht gnicudortni erehw ,Note the perfect reversal (I rarely type that accurately in forward mode). A day later it happened again: )1.3.5( noitceS fo hpargarap dnoces eht ni ,niaga ecnO.I've been using Kile for almost a year now, on two different machines and under several versions of openSUSE. Nothing remotely like this has happened before. I don't think I have a virus. I can't think of any event that may have heralded this mystical behaviour. Cheers, jdw

I'm learning Haskell from an on-line tutorial, and trying to figure out how I/O works. I'm a bit confused with this example:
Code:
My expectation is for it to ask me for a line, then for it to convert the line I provide to uppercase (err... create a new line that is uppercase) and then output said line.
However, what actually happens when I run it is it firsts ask me for a line, then outputs "Next line: ", then outputs the uppercase line:
Code:
I realize that Haskell is not an imperative language, but I was (mistakenly?) under the impression that there was some kind of sequence guaranteed in the do blocks. Could someone explain why this happens, and how I can "fix" my code to get the desired behavior?
I'm running:
- Linux version 2.6.34-gentoo-r12 (64-bit)
- GNU bash, version 4.1.9(2)-release (x86_64-pc-linux-gnu)
- Glasgow Haskell Compiler, Version 6.12.3, for Haskell 98, stage 2 booted by GHC version 6.12.3

I want to change the parameter for ThreadLimit for one file as shown below using sed. I want to ignore the commented line. But the command I am using also executing with commented line.
# ThreadLimit: maximum setting of ThreadsPerChild
ThreadLimit 25
I want the desired output as
# ThreadLimit: maximum setting of ThreadsPerChild
#ThreadLimit 25
ThreadLimit 50
For this I am using command.
sed '/ThreadLimit/{;h;s/^/#/p;x;s/ .*/ 50/;}' test.txt.1 > test.txt

Say I have a text file with10 columns. I need to reorder them based on a list of column numbers that will reorder them.
My problem is this:
If I want to cut out 5 columns (columns 1,2,3,9,10) in the order 1,10,2,9,3 then I have tried using:
Code: cut -f1,10,2,9,3 my_file.txt > reordered_file.txt But this just extracts the columns in order as if I used:
Code: cut -f1,2,3,9,10 my_file.txt > reordered_file.txt How can I cut these columns and place them into the new file in the order I specify?
While this might seem quite trivial, I will actually need to do this for a file containing ~14000 columns with ~12000 columns that I need to extract in a particular order.

When I parse a XML file, should I rely on the order of elements?
For example say we have:
Should I rely on the above order?
Would the following still be valid:
I'm trying to find out if a well formed XML document should have an ordered structure, or if it's still valid XML if it has no order.

Examples:
Code:
$ ./test.sh -a -c 2
operator is -gt
remcount is
^ value missing!
Code:
$ ./test.sh -b -c 2
operator is -lt
remcount is
^ value missing!
Yet when "-c" is the first argument, its value is present:
Code:
$ ./test.sh -c 2 -b
operator is -lt
remcount is 2
What could I do to ensure the value of "-c" is picked up regardless of the argument order?

Probably a stupid sounding question, but bear with me please. I need to use the link grammar parser in order to do some part of speech tagging. It's freely available and works once you run the makefile or 'make' it or however it's correctly said. Thing is, it has a C API which I intend to use. And once I ran a bit of the sample code given in the documentation it gave a whole host of errors. This is very confusing because I'm including the path for the folder that has all the header files.
gcc -I/path/include/ filename.c. But it still gives me errors about not being able to find things that are clearly defined there. An hour of trudging around the internet tells me I need to 'compile' the API first. I'm not exactly sure how or if I'm supposed to do that. If someone could just shed light on this it would be greatly appreciated. I grow increasingly cynical to the musical swell of my tiny brain rattling in my skull.

I'm trying to add local sockets in my multi-threaded application in order to exchange data between threads. The only problem I got is that most of the information available on the net is related to internet oriented socket programming whileI want to perform local connections. got a thread that does the sniffing via libpcap. And I would like that thread to send each captured packet to a second thread that will analyse the packetof the thread implementations is written in separate .h file.Or maybe there is a more effective method of exchanging data between threads
