Bom Sabado Worm Fix for Orkut

Most of the new orkut users are affected with a worm called “BOM SABADO”. Please refrain from login into the new orkut, or you switch to the old one. This worm will send scraps to all of your orkut friends. For safe side you can change your google account password.

You can get out of this virus by using firefox addon Adblock plus  

After installing Click go to Preferences-> Add filter and enter *tptoos.org/* .

Also Revoke the access to worm in your google account settings.

1. Go to google account settings
2. In Security ,”Change authorized websites”
3. Revoke the access from “stapi.snacktools.com”
4. Switch to old orkut, until google had a fix over it.

Happy Social Networking!!!!!!!!!!!!!!

ELMAH (Error Logging Modules and Handlers)

HTTP modules and handlers can be used in ASP.NET to provide a high degree of componentization for code that is orthogonal to a web application, enabling entire sets of functionalities to be developed,packaged and deployed as a single unit and independent of an application. ELMAH (Error Logging Modules and Handlers) illustrates this approach by demonstration of an application-wide error logging that is completely pluggable. It can be dynamically added to a running ASP.NET web application, or even all ASP.NET web applications on a machine,without any need for re-compilation or re-deployment.The end-user(if allows) can view the exception/inner exception logged in the server,Its description and even the screen-shot of the
error page

Two free security tools from Microsoft SDL team

The SDL team here at Microsoft released a couple of new tools recently to help development teams verify the security of their software before they ship. BinScope Binary Analyzer and MiniFuzz File Fuzzer are both being offered as free downloads. The team took the time to make sure that both tools work as stand-alone tools as well as integrated into Visual Studio and Team System.

BinScope is a verification tool that has been used inside Microsoft for several years to help developers and testers confirm they are building their code to use compiler/linker protections required by the SDL. BinScope allows you to scan your code to verify you are setting important security protections such as /GS, /SafeSEH, /NXCOMPAT, and /DYNAMICBASE. In addition it checks to see that you are using .NET strong-named assemblies, good ATL headers, an up-to-date compiler, and not using dangerous constructs such as global function pointers.



Both of these tools are equipped to easily integrate with Visual Studio 2008 Pro as well as Team Foundation Server 2008 and Team System 2008. By installing BinScope as integrated, it can be launched and output results within the Visual Studio IDE. MiniFuzz can be installed as an external tool add-in. Both tools have easy-to-set integration with Team Foundation Server 2008 and compliment the SDL Process Template for VSTS.

Writing secure code is becoming very important to most development teams. I am glad to see the SDL team making these types of tools available to the Visual Studio development community and making it easier to ship more secure code.

Google Wave: the sky is falling!!!

Google Wave is a product that helps users communicate and collaborate on the web. A "wave" is equal parts conversation and document, where users can almost instantly communicate and work together with richly formatted text, photos, videos, maps, and more. Google Wave is also a platform with a rich set of open APIs that allow developers to embed waves in other web services and to build extensions that work inside waves.

A wave is equal parts conversation and document. People can communicate and work together with richly formatted text, photos, videos, maps, and more.

A wave is shared. Any participant can reply anywhere in the message, edit the content and add participants at any point in the process. Then playback lets anyone rewind the wave to see who said what and when.

A wave is live. With live transmission as you type, participants on a wave can have faster conversations, see edits and interact with extensions in real-time.

So is Wave going to threaten RIA platforms? I don’t know. Is it even an RIA platform? I just think that all the messages about how Wave is pushing out things like Flash, Silverlight or JavaFX are unfounded at this point. They all serve purposes.I still requested for an invitation to join waves,but not yet received from google.One who got invites can invite 8 more people,if then so please invite me to mail@renjucool.com

Data Recovery/Live Software-ERD Commander

RD Commander is a very useful tool that Microsoft acquired with it’s purchase of Winternals. It’s especially useful for computers that aren’t able to boot into Windows, or even safe mode. ERD (Emergency Repair Disk) allows access to Windows restore points, file recovery, crash analysis, hotfix uninstall, and other low level operating system tasks, all in a very familiar Windows interface. It also provides network and internet access, as well as a web browser.


The full version is intended for IT professionals, and is available only as part of the Microsoft Desktop Optimization Pack for Software Assurance customers. However, you can download a free-trial as part of the Microsoft Diagnostics and Recovery Toolset. After downloading this toolset, install it to find an ISO file containing ERD Commander:

C:\Program Files\Microsoft Diagnostics and Recovery Toolset\erd50.iso

An ISO is a special file that when burned to a CD can create a bootable CD. Windows doesn’t support ISO burning without third-party software. ISO Recorder is a very simple, and free program for creating CDs from ISOs. After you’ve burned the CD from the ISO, simply boot the system from the CD you just created to start ERD Commander. If your system doesn’t boot from the CD, you might have to change the BIOS boot settings (boot order).

A couple of caveats. The trial version of ERD Commander is ERD Commander 2005. The latest version (currently ERD 6.0) is only shipping with the Desktop Optimization Pack. While version 6.0 is Vista compatible, 2005 is not (compatible with Windows NT, 2000, XP, and Server 2003). The trial period is 30 days. Next time you’re faced with an unbootable Windows XP system, give ERD Commander a try.

Disk I/O:The Performance Bottle neck

Many people think of "performance tuning" as optimizing loops, algorithms, and memory use. In truth, however, you don't get the huge performance gains from optimizing CPU and memory use (which is good), but from eliminating I/O calls.

Disk I/O is responsible for almost all slow websites and desktop applications. It's true. Watch your CPU use next time you open a program, or your server is under load. CPUs aren't the bottleneck anymore - your hard drive is. At the hardware level, the hard drive is the slowest component by an incredibly large factor. Today's memory ranges between 3200 and 10400 MB/s. In contrast, today's desktop hard drive speeds average about 50 MB/s (Seagate 500GB), with high-end drives getting 85MB/s (WD 640, Seagate 1TB). If you're looking at bandwidth, hard drives are 200-300 times slower. Bandwidth, though, isn't the killer - it's the latency. Few modern hard drives have latencies under 13 milliseconds - while memory latency is usually about 5 nanoseconds - 2,000 times faster.

You're probably looking at these numbers and thinking, "13ms is quite fast enough for me, and my app is only dealing with small files". However, I have a question: what other applications are using that drive? If you're on a shared server, the odds are high that between 25 and 2500 ASP.NET apps are being run on the same drive.

CPU, bandwidth, and memory throttling is becoming more and more common on shared servers and virtualization systems, but practical disk throttling isn't even on the horizon from what I can tell. Improper I/O usage from any app affects everybody.

Since hard drives are slow, pending operations go into a queue. So even if your app only needs a single byte of data from the hard drive, it still has to wait its turn. It's quite common for disk operations to take several seconds on a shared server under heavy load. If any application on the server is paging to disk from exessive memory use, it can take several minutes, causing a timeout.

Realistic I/O performance is really hard to simulate in a development environment. On a dedicated development machine, disk queues are short, and response times are usually near the optimal 13ms, which tends to give software developers gravely incrorrect ideas about the performance characteristics of their application.
