Blogger blogspot URL prompts users before redirecting to custom domain

Bookmark and Share

Due to some reasons, one of the URL(s) to access techsutram blog, http://techsutram.blogspot.com, is prompting users with question “Do you wish to be redirected?” unlike its previous behavior.  It also states that “This blog is not hosted by Blogger and has not been checked for spam, viruses and other forms of malware.” (?).

Blogger Redirecting page

Previously users navigating to techsutram.blogspot.com were seamlessly redirected to www.techsutram.com. I am not exactly sure about the cause of this sudden behavior.

The redirection page also states that “techsutram.com” is not hosted by blogger. This is again confusing as  “techsutram.blogspot.com” was moved to custom domain “techsutram.com” using blogger dashboard and all posts on this blog are indeed posted using blogger service.

Just found entry for this issue at knownissues.blogspot.com

Is there anyone facing similar issue?

Bookmark and Share

All Unix users know how it is difficult to tail output of multiple files at a same time. Though ‘tail’ CLI available with LINUX is capable of giving just right output for multiple files, this flexibility is not available on all platforms.

I just came across a handy tool called ‘MultiTail’. ‘MultiTail’ functions similar to traditional ‘tail’ CLI except for the fact that it will able to monitor tail output of multiple files at the same time. ‘MultiTail’ is supported on Solaris, Linux, *BSD, IRIX, HP-UX, AIX, Tru64, SCO OpenServer platforms and also runs under Cygwin on Windows. ‘MultiTail’ has lots of features unlink ‘tail’ CLI.

Download MultiTail source and compile it on supported platforms and we are ready to go. MultiTail example page displays its sample usages. Don’t forget to look at screenshots before installing MultiTail.

Bookmark and Share

With recent releases of web browsers such as Internet Explorer 8, Mozilla Firefox 3.0, Mozilla Firefox 3.5 RC, Google Chrome 2.0, Opera 9.6, here comes another web browser release Apple’s Safari 4 to heat up the web browser wars. Each of these browsers competing with each other in terms of rendering (HTML,JavaScript) speed. Now Apple’s Safari 4 claims that it is one of the fastest of all web browsers.

Safari Performance : i-Bench HTML

Safari Performance : i-Bench JavaScript

Safari Performance : SunSpider JavaScript

It is interesting to note that all above screenshots displays latest Mozilla Firefox 3.0 browser considering that I am a fan of Firefox.

Apple’s Safari 4 can be download from here.  Below is CNET video for Apple’s Safari 4.

So from software developers and testers perspective, it will eventually become mandatory to support and test all major browsers for their web based products as eventually people will have multiple options for web browsers in near future.

So which web browser will you prefer?

Bing search is Live

Bookmark and Share

Microsoft’s latest search engine Bing is live. Get the tour of Bing features at www.discoverbing.com

I have tried to search for term “techsutram”. This is how it resulted on Bing (in image below). It returned 26 results unlike 431 results from Google. ( This may be due to beta version of Bing unlike full-fledged GA version of Google search.)

Bing: Search for "techsutram"

Well! it was a quick test. You can try different terms such as politics, finance, MACD etc…

However, Bing has pretty good enhancements over Google results. That makes everyone easy to navigate trough Bing search results.

So next time when you want to web search, will you say Bing or Google?
