I experienced recently that I was unable to hit and click in flash based application using the mouse, which meant that I was forced to use the keyboard to navigate in all flash application – not a good user experience and very annoying. Adobe Flash does simply not register any mouse clicks (e.g. on YouTube, Google Analytics, etc.).
However I have researched on the bug, actually it was quite difficult to find anyone, who had experienced problem and reported it, also because the problem is hard to describe consistently. This fact was also clear, when I read the Ubuntu bug report.
The descriptions of the problem varies a lot: “Clicking on items in Flash player does nothing”, “I Cannot Click On Flash In Ubuntu”, “Flash does not register any clicks”, and “flash does not recognise mouse clicks”.
Solution
- Hit ALT+F2 and enter
- gksudo gedit /usr/lib/nspluginwrapper/i386/linux/npviewer
- add the following line BEFORE the last line of text
- export GDK_NATIVE_WINDOWS=1
- Save.
- Restart any applications using flash

The German authorities are encouraging Internet users to immediately abandon the use of Internet Explorer for security reasons.
The Web browser from Microsoft is the most widespread in the world, but the German authorities consider that the Internet Explorer is vulnerable to attacks from hackers. The warning comes from the Bundesamt für Sicherheit in der Informationstechnik, which is a department in charge of overall IT security in Germany.
Vulnerability Triggers The Concern
Authorities advises citizens to use alternative browsers. A web browser is a computer application that is used to retrieve and display among other web pages from servers around the world.
The concern arised when Google last month, was attacked by Chinese criminals or authorities, where many e-mail accounts were hacked. Hackers also tried to break into approx. 30 companies.
Microsoft rejects the warning and finds that the risk of attacks against ordinary users is low. A spokesman for Microsoft in Germany, Thomas Baumgaertner, therefore states, that the German authorities over-react: “The attack was not directed against ordinary citizens or consumers. It is not a threat to the general user, and therefore we are not up hills on this warning.
New updates on the way it is version 6, 7 and 8 of Internet Explorer
Microsoft said the company already has started to solve problems and that new updates are coming. Windows systems; XP, Vista and Windows 7 are apparently is affected by the vulnerability.
Google Chrome and Mozilla Firefox are both good an better designed alternatives to Internet Explorer.

Secure Connection Failed
An error occurred during a connection to 192.168.12.122.
You have received an invalid certificate. Please contact the server administrator or email correspondent and give them the following information:
Your certificate contains the same serial number as another certificate issued by the certificate authority. Please get a new certificate containing a unique serial number.
(Error code: sec_error_reused_issuer_and_serial)
The page you are trying to view can not be shown because the authenticity of the received data could not be verified.
* Please contact the web site owners to inform them of this problem.
Solution
If you have recieved this error and are trying to access something that has a self signed certificate, there are two places in Firefox that you must visit in order to access the particular site again.
The first visit Tools–> options–>Advanced–>View Certificates
You must remove the certificates in the “Servers” tab, then under the same location you must remove the certificate authority because it is a self signed certificate, so on the “Authorities” tab, simply find the CA for the device you are having trouble with and delete it.

What is Safari? It is a browser. It is a platform. It is an open invitation to innovation. Safari expands the boundaries of the Internet and gives you also a world-class user experience.
It is now possible to download and install Apple’s Safari Web browser on your Windows platform. Note that the client is in beta and therefore probably, but it works flawless on most machines.
Apple Safari can be downloaded from here.

Developing a web applications is often articulated as easy and a good thing for new programmers to start with. Many books and tutorials have been written on the subject, and many frameworks and programming languages have been built to facilitate quick construction of web applications. Just one thing bothers me about this, many of the books and tutorials ignore many of the security issues that are related to building web applications. This fact might explain why we do have such a huge number of insecure and vulnerable web applications around on the net.
Anyway, it is not just bad – a number of initiatives have been formed to communicate the need for security and web-based applications. One of these initiatives is OWASP, which is an open-source application security project. The OWASP community includes corporations, educational organizations, and individuals from around the world. This community works to create freely-available articles, methodologies, documentation, tools, and technologies.
OWASP’s most successful documents include the book-length OWASP Guide and the widely adopted OWASP Top 10 awareness document. The most widely used OWASP tools include their training environment WebGoat, their penetration testing proxy WebScarab, and their OWASP .NET tools. OWASP includes roughly 100 local chapters around the world and thousands of participants on the project mailing lists. OWASP has organized the AppSec series of conferences to further build the application security community.
Hopefully initiatives like OWASP will provide up-coming web developers with a awareness of the security issues related to development of web application and enable them to avoid the classic pitfalls in web application security. At least so far I have learned a lot from OWASP articles and guides.
