Ruby and FLVTools2
FLVTool2 is a manipulation tool for Macromedia Flash Video files (FLV).
FLVTool2 can calculate a lot of meta data and insert a onMetaData tag. It can cut FLV files and add cue Points (onCuePoint). A debug command lets you see inside our FLV and the print command gives you meta data information in XML or YAML format.
FLVTools2 Features:
* batch processing
* directory recursion
* command chaining
* cut FLV files
* onCuePoint tag insertation via XML file
* custom onMetaData key-value pairs
* meta data printout in XML or YAML
* simulation mode
* runs under Windows, Linux and Mac OSX
* ideal for serverside automatic meta data injection
And today I found that FLVTools2 could not run on Red Hat Enterprise 3 – Ruby version 1.6.x

I believe most of the Linux users complain about the Linux boot up speed. Everyone wants a quick boot time.

Google Webmaster Guidelines
Just to share a good articles as below:
Google [tag]Webmaster[/tag] [tag]Guidelines[/tag]
- Make sure your pages have less than 100 links. This won’t be too difficult
unless you display product lists without breaking them up into separate
pages (which should be done for your visitors let alone search engines!)
or have a link partners page or a site map. If you have more than 100
outbound links, you may want to review your linking practices unless you
have compiled a comprehensive list of high quality and relevant resources
for your visitors. - Dynamically-generated content can create session IDs and URLs that contain
a “?” character. Chëck your database administration settings to make sure
that you aren’t forcing search engine spiders to begin a new session each
time they visit your site. *Note:* Preventing spiders from starting a
session on your site may have negative effects if you use a third party
for web site credít card processing. Always chëck with these services
before making any changes of this nature. - Web designers still utilize images as a way of displaying headings or
other important areas of text instead of simple HTML simply because they
think the Book Antiqua font with a drop shadow improves the aesthetics of
the site. While branding and clarity are always paramount, keep in mind
that multiple fonts used on the same page can have a negative impact on
readability. And the more text written in HTML that can be read by search
engine spiders, the better. CSS (Cascading Style Sheets) also provide a
way of attaining the look you want while keeping the code clean and in
search engine-readable format. - “/Make sure that your TITLE and ALT tags are descriptive and accurate/.”
Most webmasters assume that by using keywords in the page title that are
relevant to the page’s topic, that they are adhering to the rules. But
that last word in quotes is the most important: Accuracy. It is standard
practice for search engine optimizers to make sure that if a word is used
in a page title, that it also shows up in the main body of the page as
well. Not doing this means that Google may be interpreting your page
titles as inaccurate or at worst, trying to manipulate its algorithm. - Use 301 redirects to let visitors know if a URL has changed. Many people
still use the “meta refresh” command. This is an outdated command that has
been utilized in the past for unethical purposes. While visitors can be
directed to the new page the same way with either method, Google
specifically mentions using a 301 redirect. More information on how to
implement this redirect can be read athttp://knowledge.freshpromo.ca/seo-tools/301-redirect.php
- Google suggests you submit your site to the Yahoo! directory. Why would
Google urge its users to pay a direct competitor of theirs $299 USD a
year? It is safe to say that web sites included in the Yahoo! directory
are not trying black hat SEO techniques such as free-for-all link
exchanges, cloaking, multiple domains showing duplicate content, and so
on. Companies that spend monëy promoting their web site should receive a
vote of legitimacy from search engines. As difficult as it might be for
some small business owners to bite the bullet with Yahoo’s yearly cost,
having Google recognize that you have paid for directory listings will
increase the chances that your site will rank well.

Linux Server Hack
What your [tag]Linux[/tag] Server was hacked again? I’m received a call from my friend and he said his customer Linux [tag]server[/tag] was [tag]hacked[/tag] by someone again yesterday.
After the phone conversation, I found that his Linux Server was hacked because of password [tag]brute force[/tag].
What is a brute force attack?
Brute force attack is a method of defeating a cryptographic scheme by trying a large number of possibilities; for example, exhaustively working through all possible keys in order to decrypt a message. In most schemes, the theoretical possibility of a brute force attack is recognised, but it is set up in such a way that it would be computationally infeasible to carry out. Accordingly, one definition of “breaking” a cryptographic scheme is to find a method faster than a brute force attack.
