Programming :: Implementing Search Engine Optimization (SEO)
Mar 31, 2011
Though I have developed some web applications (automation tools) using PHP which have been primarily meant for Intranet (within the organizations I have worked for), I have paid little attention to SEO (it was not required until now). But now I want to understand how do we go about implementing SEO and where do we fit this mechanism in a system / website?
Do we need any other tools or learn some specific programming /scripting language to achieve it?Will implementing a good SEO yield identical results irrespective of what search engine (be it Google or Yahoo!) is being used by users?

I have a CENTOS server with Samba installed and a share with about 2 TB of various files (pdf, word, excel, text file, jpeg). I'm looking for an application can help to search quickly inside this large archive. The better solution could be a web interface where each client (normally a windows XP client) could do a search..

I have been using Epiphany for about 10 days now. It seems that suddenly my search engine was changed from Google to VirginMedia.I cannot find any option to set the default search engine, either in Epiphany preferences or in gconf-editor.Can anyone explain how this change has occurred or how I might get back to having Google as my default search engine? I am using Debian Lenny 5 and Epiphany 2.22.3

I found that "ask search engine" installed as default web search engine instead of google in firefox. Now it's impossible to go back to google search engine as "ask" always remains as default search and no other search engins are shown in the firefox list.Any idea about how to get rid of "ask"? I managed to install another "unofficial google" search plugin but if i click on restore default search engine "ask" will be restored.

Can Fedora change its default search engine to Yahoo! just like Ubuntu is about to change its default search engine from Google to Yahoo!? I'd love that.I don't like Google. Too many unnecessary repetitive indexing of the same or slightly changed titles to links for the same sites. I've always liked Yahoo! from the start.

Does anybody have strigi krunner plugin work as search-engine and not as lottery? Same goes with search desktop containment - when typing in few letters from the file name, it never founds the file, only displaying ca 10 random files based on content(i guess) instead.

I'm looking for a simple and reliable search engine for searching particular content on the files in the storage database. The output will display files' name and their path. Google search found following site:- "List of search engines";[URL]..There are many of them. I have no idea how to make my selection. Could you please shed me some light. Furthermore can a simple shell command do the same job?

I work on Linux for ARM processor for cable modem. There is a tool that I have written (as the job demands) that sends/storms customized UDP packets using raw sockets. I form the packet from scratch so that we have the flexibility to play with different options. This tool is mainly for stress testing routers.
The details are here.
I actually have multiple interfaces created. Each interface will obtain IP addresses using DHCP. This is done in order to make the modem behave as virtual customer premises equipment (vcpe).
When the system comes up, I start those processes that are asked to. Every process that I start will continuously send packets. So process 0 will send packets using interface 0 and so on. Each of these processes that send packets would allow configuration (change in UDP parameters and other options at run time). Thats the reason I decide to have separate processes.
I start these processes using fork and excec from the provisioning processes of the modem.
The problem now is that each process takes up a lot of memory. Starting just 3 such processes, causes the system to crash and reboot.
I have tried the following:- 1-I have always assumed that pushing more code to the Shared Libraries will help. So when I tried moving many functions into shared library and keeping minimum code in the processes, it made no difference to my surprise.
2-I also removed all arrays and made them use the heap. However it made no difference. This maybe because the processes runs continuously and it makes no difference if it is stack or heap?
3-I suspect the process from I where I call the fork is huge and that is the reason for the processes that I make result being huge. I am not sure how else I could go about. say process A is huge -> I start process B by forking and excec. B inherits A's memory area. So now I do this -> A starts C which inturn starts B will also not help as C still inherits A?. I used vfork as an alternative which did not help either. I do wonder why.
reduce the memory used by each independent child processes.

I want to move files from a $SOURCEDIR to a $DESTBASE/$DESTDIR. Under $DESTBASE there are many directories, and I need to test beforehand if a file from $SOURCEDIR already exists in any of them.
This is obviously extremely slow, and the real use case involves dozens of dirs and thousands of files. Creating a temporary "index" file for the find command (instead of running it every iteration) speeds it up a little, but it's still very clumsy.

I'm interested in writing a generational garbage collector in C++. This is for a Python-like programming language project. I have used Boehm's garbage collector before, but I'm worried that it will have noticeable pause times (unacceptable for interactive programs). Since I can't really find any other C++ established GCs out there, I have been thinking of simply writing my own.
However, there are two essential ingredients I need for this:
- Some kind of write barrier mechanism that will notify my collector when something is written to a part of the heap
- A way for me to know the addresses and sizes of the stack, heap and global storage (the root sets)
how to implement write barriers (and how to get the stack, heap and global storage information) on the Linux platform? As an alternative, if you know of C++ GCs other than Boehm, I would also be interested.

implementing hamming code in c: Calculating the Hamming Code The key to the Hamming Code is the use of extra parity bits to allow the identification of a single error. Create the code word as follows:
Mark all bit positions that are powers of two as parity bits. (positions 1, 2, 4, 8, 16, 32, 64, etc.)
All other bit positions are for the data to be encoded. (positions 3, 5, 6, 7, 9, 10, 11, 12, 13, 14, 15, 17, etc.)

I run Wheezy Xfce 64-bit. I went through the Synaptic listings and added Python 3.3.2 and Tkinter for it, and that works fine; but for some reason PyGtk is available only for Python 2.7, not for Python 3.3, unless I'm just using the wrong way to try to find it. Is there a PyGtk available for Python 3.3 in Wheezy, and, if so, how do I install it and then import it once it's installed?

Options:A double linked list with fixed size character arrays. New nodes will be added when previous ones get filled. Dynamic arrays using realloc(). Linked list has the disadvantage of not having an O(1) search like an array but I think using realloc() will be more dangerous since it moves the whole block to a new location and if the new location is not big enough to hold the whole block, realloc fails !! this case will not occur with the linked list since its nodes are scattered.

I need to implement AIDE on my client machines. The builds on these machine are different, so each workstation will have its own specific db generated through running AIDE initially. It is not good practice to just leave the db on the machine, since an "attacker" would be able to view this information. However, at the same time I do not want to pull back over 100 different aide db's to the ftp server and have an update pull each specifically every time I need to run the check. The plan is to leave the db on the client machine, but encrypt it (using public/private keys). I need to be able to encrypt the file on the client machine. I will use a cron on the client to pull an update (from my ftp server) that runs AIDE. This update needs to be able to decrypt the file, use it running AIDE, then re-encrypt the file on the client.

I am a newb on linux and I really need some help on how to get my job submitted through sun grid engine. This is the script I need to submit
#!/bin/sh -f
FILE=$1
LGFL=`echo $FILE | sed 's/.$//' | sed 's/.$//'`
echo "Running -> " $FILE
echo "Octave Output -> " $LGFL".log"
nohup /home/guol2/octave-3.2.4/run-octave -q < $FILE >& $LGFL".log" &
echo "Command Started"
It basically stats Octave and run a file I typed after. So if I need to submit it through sun grid engine how would I type it in command line or how should I do it in the sun grid engine control panel. I tried qsub -o <my path> -e <my path> run_octave Myfile.m (Myfile.m is the file I need to run)

How can i use grep (or any other command) to check for lines that begin with N number.
E.g. I want to print out commands (from history), but only from the command number 50 until #200.
This one doesn't work:
Code:
history | grep "^[50-200]"
Should print out something like:
Code:
50 cd ~/Desktop

hey guys, im doing a simple search program and i came up with a problem. What i am trying to achieve is, if the search is false(means the book does exist) , the program will then ask the user to input the information again(title and author) and do a search again until there is no such book and then display a message saying he can input a new book in.i tried using a until loop, but it does not seem to work. some guidance on how the statement should be and where should it be placed?
