How To Open 2 Gmail accounts with the same Firefox Version

Here’s the trick below to open multiple gmail accounts with the same version of firefox.

1. Open the Run dialog. In linux, press Alt+F2. On Windows, press WinKey+R.
2. In the dialog box, type “firefox -p -no-remote”. This will bring up firefox’s profiles dialog box.
3. Click on “Create Profile” and follow the wizard. Lets assume you named the profile as “gmail2“.
4. Now close the dialogs and return to desktop.

Now, open the Run dialog again. In the dialog box, type “firefox -p gmail2 -no-remote“.

“-no-remote” option is very important because it creates an isolated session that is different from the currently open firefox windows of other profiles. If -no-remote option is not given, then a new window of the currently running profile or the default profile is opened, where session sharing happens (which we don’t want).

Now, since sessions aren’t shared between different profiles, you can open two accounts and happily have them.

PHP – Prevent SQL Injection

SQL injection vulnerabilities have been described as one of the most serious threats for Web applications. Web applications that are vulnerable to SQL injection may allow an attacker to gain complete access to their underlying databases.

Because these databases often contain sensitive consumer or user information, the resulting security violations can include identity theft, loss of confidential information, and fraud. In some cases, attackers can even use an SQL injection vulnerability to take control of and corrupt the system that hosts the Web application.

SQL injection refers to a class of code-injection attacks in which data provided by the user is included in an SQL query in such a way that part of the user’s input is treated as SQL code.By lever-aging these vulnerabilities, an attacker can submit SQL commands directly to the database. These attacks are a serious threat to any Web application that receives input from users and incorporates it into SQL queries to an underlying database.

The cause of SQL injection vulnerabilities is relatively simple and well understood: insufficient validation of user input.

ypes of SQL injection attacks:

Union Query:
In union-query attacks, an attacker exploits a vulnerable parameter to change the data set returned for a given query. With this technique, an attacker can trick the application into returning data from a table different from the one that was intended by the developer.

Attackers do this by injecting a statement of the form: UNION SELECT <rest of injected query>.

Because the attackers completely control the second/injected query, they can use that query to retrieve information from a specified table. The result of this attack is that the database returns a dataset that is the union of the results of the original first query and the results of the injected second query.

1: 2: 3:

SELECT accounts FROM users WHERE login='' UNION SELECT cardNo from CreditCards where acctNo=10032 -- AND pass='' AND pin=

Assuming that there is no login equal to , the original first query returns the null set, whereas the second uery returns data from the CreditCards table. In this case, the database would return column cardNo for account 10032. The database takes the results of these two queries, unions them, and returns them to the application.
In many applications, the effect of this operation is that the value for cardNo is displayed along with the account information.

How To Create Stylesheet only for IE

Sometimes it is better to create alternate css files for different browsers (esp. IE), than using hacks. It is important in big projects, when client requires the site to be fully cross-browser. The basic technique to attach an IE-Only stylesheet is using the HEAD section conditions:

CSS FILE LOADED FOR BROWSERS OTHER THAN Internet Explorer:

<![if !IE]>
<link rel=“stylesheet” type=“text/css” href=“NOT-IE.css” />
<![endif]>


 IE 6 ONLY CSS FILE:
<!??[if IE 6]>

<link rel=”stylesheet” type=”text/css” href=”IE-6-SPECIFIC.css” />
<![endif]??>

IE 5 ONLY:

<!??[if IE 5]>

<link rel=”stylesheet” type=”text/css” href=”IE-5-SPECIFIC.css” />
<![endif]??>

IE 5.5 ONLY:

<!??[if IE 5.5000]>

<link rel=”stylesheet” type=”text/css” href=”IE-55-SPECIFIC.css” />
<![endif]??>

VERSION OF IE VERSION 6 OR LOWER: (I find this one pretty handy)

<!??[if lt IE 7]>

<link rel=“stylesheet” type=“text/css” href=“IE-6-OR-LOWER-SPECIFIC.css” />
<![endif]??>

IE 7 ONLY:

<!??[if IE 7]>
<link rel=“stylesheet” type=”text/css” href=“ie7.css” />
<![endif]??>

The biggest advantage of using this methos is that it passess W3C validation and you don’t have a mess of different hacks in your css code.

10 Steps to Professionalise Your Joomla Web Site

Create a new favicon.ico.
Yes, the default black Joomla logo is pretty, but people bookmarking your site they need to see a icon that identifies your site rather than Joomla or others using Joomla default icon. If you don’t want to design on a 16×16 pixels scale, there are sites that will generate a favicon for you. Then upload it to /template//favicon.ico
Make sure you backup your database everyday.
We recommend the JoomlaPack – AJAX powered backup and restore

Don’t cut and paste from Microsoft Word.
It may be easy but MS Word produces some of the worst HTML ever. Cut and paste into a text editor such as Notepad or WordPAD before adding that content to your site.

Make sure you put the Search button in an observable position.
A search of the latest 20 sites on the Joomla forums showcase reveals that more than half doesn’t have a clearly visible search button.  Low on the left or right hand column is not good places. Try and put it close to the menu so that people’s eyes are logically drawn to it.

Utilize “Read More”.
Lots of visitors will never get past your homepage. Make sure that your homepage is not a long text area and start creating some “tease” –short content. In general, articles should not be longer than 4 or 5 sentences, followed by a “Read More…” link.

Content >> Unpublish the PDF and Print options.
These generate duplicate content problems in Google and may delay your SEO success.

Server >> Use Server Defaults.
Setting this to 777 or 775 creates a big security hole on your site.
Metadata. Don’t overload here. Keep it to a maximum of 6 description words and keywords. These will show on every page and you want to allow each page to have its own keywords.

Cache. Turn cache on from Global Configuration-> System.
Your site will run faster. The cache function saves copies of the web page as file so that users don’t have to load your whole page and make many database connections every time they visit.

Statistics. Turn them off!
They’ll slow your site performance down. Go and get Google Analytics instead. Click here to see how to insert Google analytics to your joomla site.
