Today, we managed to implement a solution that allows RTL Arabic support for OpenERP 5.0.11 reporting engine on our openSuSE 11.1 64 bits server.

It has to do with enabling RTL in ReportLab, which is used by OpenERP to produce PDF reports. Also, OpenERP server code has to be patched to allow it to identify RTL and LTR test direction. OpenERP reporting engine is by default recognizes LTR only.

Support for unicode characters has to be enabled to allow the display of Arab and Hebrew characters.

No more details can be provided as although the solution is open source, we don’t have the permission from the author to publish it.

Getting your website ranking as high as possible with major search engines is crucial for your business. It also gives you winning advantage against your competition. We will discuss in this article several factors that contribute to how high you can go on a search engine query result.

Please realize there is no such thing as a magic silver bullet that will vault you to the top of the search engines – if there were, everyone would know it, they would do it, and it would cease to work because of saturation.

Several strategies contribute to this, as you can see from the following. First, we will discuss the general strategies and techniques used with all major search engine. Then we will discuss the specific the specifics of what is currently working on each of the major search engines.

Part One : General Guidelines

Choosing your domain name :

One of the most basic, yet critically important, strategies is to use your best keywords in your domain address. An example would look like…

http://www.laptopshome.com

http://www.notebooksforsale.com

The reason for doing this is because search engines and directories assume the domain to be relevant to the keyword. It’s something that, in practicality, can’t be faked.

Getting your keywords into your domain name is strategically critical and chances are it will only become even more important in the future. Remember, by registering all possible keyword combination domain names you can think of you not only have them available to your company when needed but you’ve also prevented your competition from securing them and using them against you.

If your company name is your domain name, then that’s fine but you should still register all relevant keyword-rich domain names pertaining to your goods and services. This will give you the option of setting up specialized sites that place your services into the paths of the engines and directories.

Getting Your Web Page Titles Right :

This is all about your pages <TITLE> tag. Note in mind that Title is the most important aspect of web page design in respects to scoring well on most search engines.

Always make sure every word in your title is one that is likely to be used by a person when doing a keyword search for your business or service. AND, keep in mind that unless the name of your business is prominently recognized or likely to be used in a keyword search – something like “SONY cameras”, it does NOT belong in the Title tags.

Keyword Selection Techniques :

Make a list of every possible search word (keyword) and search phrase (keyphrase) that your potential customers
might use when looking for your information, product or service. Remember to include synonyms as well as the common misspellings of your keywords and pay particular attention to noun phrases. Next, use these keywords and keyphrases to find your competition on the top search engines.

Keyword Relevancy :

Simply put, your keywords must be relevant to the contents, or theme of your web page.

Keyword Density :

By this I mean the number of times your keyword(s) appear in relation to the other words on your web page.  Theoretically, a webpage that said only “Chicago” verses the “Eat at Chicago’s…” page would be given a higher score for the keyword Chicago due to a higher keyword density.

Description Meta Tag :

The meta description tag is used by many engines as the summary for your site when listed in the search results. It’s what tells a real person whether or not your site is relevant to their search. You should view it as a sales presentation for your link. If the meta description tag entices the searcher they will, theoretically, click your link and visit your site. Obviously that’s the purpose for being listed in the search engine in the first place.

Most search engines place a limit on the number of characters that a meta tag can contain. Once the limit is reached they typically ignore the rest of the tag contents. In general, 250 characters – including spaces and commas – is a good rule of thumb that falls within the guidelines of most engines.

Below are two firefox add-ons productivity tools that should make your life a lot easier :

QuickFox Notes :

This is a note-taking add-on for Firefox that saves notes as bookmarks in Firefox. This means you get all the convenience of browser-based note-taking, and cross-browser syncing if you’re using Mozilla Weave, Xmarks, or another method to sync your bookmarks between instances of Firefox.

Read It Later :

Read it Later is an extension that works with a Web-based service.  Here’s how it works. Once you install the extension, RiL adds a yellow icon to the “Awesome bar” in Firefox, and a similar icon to the toolbar next to your search. When you’re on a page you want to save for later, just click the yellow icon.

Google Reader fans will also love RiL because it will also clip items from Google Reader without having to view the page first. Once the extension is installed, it adds a RiL icon to Google Reader items (right next to the star). Just click that and the entry will be added to.

“Because iFolder is a cross-platform distributed solution, there is a possibility of a virus infection on a platform migrating across the iFolder server to other platforms, and vice versa. You should enforce server-based virus scanning to prevent viruses from entering the corporate network.”

This solution applies for openSuSE 11.1 :

The following packages need to be installed :

clamav
dazuko
postfix

Execute modprobe dazuko (as root)

Run lsmod and check that dazuko is loaded:

Edit /etc/init.d/boot.local

• Add:
  modprobe dazuko

Edit /etc/clamd.conf

Enable logging by activating :
LogFile /var/log/clamd

* Activate:
# Path to a local socket file the daemon will listen on.
LocalSocket /var/lib/clamav/clamd-socket

* Deactivate:
# TCP port address.
#TCPSocket 3310

* Deactivate:
# TCP address.
#TCPAddr 127.0.0.1

* Activate and edit:
# Execute a command when virus is found.
VirusEvent /bin/echo “iFolder VIRUS ALERT: %v” | /bin/mail -s “ClamAV – iFolder” -r ClamAV@server.domain ToUser@domain

* Deactivate:
# Run as a selected user (clamd must be started by root).
#User vscan

Note:
If not deaktivating “User vscan” you receive the error: “clamuko cannot connect to dazuko” in /var/log/clamd

* Clamuko settings, Activate the following :

ClamukoScanOnAccess yes
ClamukoScanOnOpen yes
ClamukoScanOnClose yes
ClamukoScanOnExec yes
ClamukoIncludePath /YOUR_PATH_TO_IFOLDER/ifolder/simias/SimiasFiles

Change any other settings in the file to reflect your needs (see ClamAV documentation).

Start clamd:
/etc/init.d/clamd start

Check that clamd was started without any errors:
tail -f /var/log/clamd

Download the EICAR test signature from:
http://www.f-secure.com/virus-info/eicar_test_file.shtml

Note!
This is not a real virus.

Run: tail -f /var/log/clamd

Save the test file (eicar.zip and/or eicar.com) in your iFolder and wait for sync.

When the virus pattern is detected you should see this (see below) in the log file
/var/log/clamd.

Check that a mail has been sent: tail /var/log/mail

Update ClamAV:
You can update ClamAV using the command: freshclam

A better way is to use the freshclam daemon for automatic updates.

Settings for freshclam: /etc/freshclam.conf

Edit /etc/freshclam.conf

• Activate:
  # Path to the log file (make sure it has proper permissions)
  UpdateLogFile /var/log/freshclam.log
• Activate and provide your country code:
  # Uncomment the following line and replace XY with your country code.
  DatabaseMirror db.se.clamav.net
• Activate and provide update interval (e.g 24 for every hour):
  # Number of database checks per day.
  Checks 24

Create a log file for freshclam:
touch /var/log/freshclam.log

Set file rights:
chown vscan:vscan /var/log/freshclam.log

Start freshclam:
/etc/init.d/freshclam start

Check the log file:
tail /var/log/freshclam.log

Activate automatic start for clamd, freshclam and postfix from Yast –> System –> System Services (Run Level).

Now you have a real-time anti-virus scanning for your iFolder3 server.
