Yesterday I downloaded a video from youtube and saved in linux. I’m using a firefox addon called DownThemAll!. It doesn’t save the download with file extension. Since I was using Fedora i was not bothered about it much. Then for some work I logged onto xp. Then I tried to play the downloaded video in windows, but it didn’t play because it was not having an File extension.I know it should be either mp4 or flv, So i tried renaming the file with extension mp4 and it worked. Then i had a doubt, what if i rename the file with the extension flv and play. So i renamed with the extension flv and played. To my surprise it the file was playing without any glitch. My questions are
- If the same file can be played without any problem in two different extensions, then what is the use of having extensions?
- If VLC player in Linux can play a file without an extension, why can’t it do the same in windows?
- On the first place, What is the reason for having a file extension?
Internet Explorer 9 (IE9) will come with cool new features, beyond what the four Platform Preview releases of the browser have offered early adopters.
While Microsoft is completely mum on the feature set for the next major iteration of Internet Explorer, the fact is that the company has already decided on the goodies that the successor of IE8 will bring to the table. Moreover, the software giant has also been sharing details related to the new features in Internet Explorer 9 internally.
This should of course, come as no surprise, especially since Microsoft is well known for dogfooding its own software (eating its own dog food, namely testing products internally). Microsoft has not confirmed officially any features for IE9, but most people expect , the wait will be certainly worth it.
With the last Platform Preview of IE9 already available, Microsoft is now focusing on wrapping up the first Beta development milestone of the browser. IE9 Beta will be a fully-fledged browser, and judging by the information will also feature some of the new features planned by the software giant. Microsoft had been holding back on us. Yes, performance is looking great – but they’ve got more up their sleeves. So, wait until the unveiling of the beta.Microsoft has already sent out the Beta invites to the Beauty of the Web event in San Francisco on September 15th, 2010, for the launch of IE9 Beta.
Still, the Beauty of the Web site offers no clues as to what IE9 Beta will bring to the table, acting only as an R.S.V.P. destination for those invited. In the meantime, check out the announcement from James Pratt on the Exploring IE blog. The post is titled Announcing the Beauty of the Web event for IE9 Beta Launch.The only clues related to new IE9 features came from leaked screenshots of an early Beta Build, which sported additions such as a download manager.
Internet Explorer 9 (IE9) Platform Preview 4 is available for download here.

Microsoft has just released the fourth and final IE9 developer preview, little bit ahead of schedule.The news is much the same as the previous release: More hardware acceleration! Faster! More standards compliant! But there’s some juicy stuff under the hood, too — read on, if you want technical details. If you want developer-level stuff, check the IE team’s new blog post. .
First, it looks like audio is now hardware accelerated. There’s both a multi-track mixer/sampling demo, and some daft Hamster Dance Revolution game — both show off strong audio processing abilities. I’ve never really thought of audio as being important for the Web platform, but I guess if we’re going to see increasingly-complex in-the-browser games and applications, having hardware audio access is highly desirable.
Next, there’s yet more support and hardware acceleration for SVG animation. Have a go with the dice rolling demo or the aforementioned music games — pretty damn cool for in-the-browser animation.
Surely it then becomes a matter of end-user experience. If IE9 launches later this year, it might have the edge for a while, but the whole point of open standards like HTML, CSS, JS and SVG is that every browser can support them. I worry that the Internet
Explorer team might produce a fantastic browser, but one that simply isn’t as.
Till now all hard drives are formatted into 512 kb blocks of size. The 512kb size came from IBM which used it on it’s Floppy drive. The problem with this is that all blocks have marker telling where the block is beginning, a dedicated area to store error correction codes. In addition to this space has to be left between each blocks which leads to wastage of space.In the above picture from the point where it is denoted as starting till the red coloured part is one block. The red coloured block represents the area where error correction codes are stored. The greed coloured parts denote the empty space between each block. As one can observe the total storage space which is usable is very less when we use 512 kb block size. This is the reason why we cannot use the full capacity of hard disk.
Now hard disk manufacturers have decided to adopt a new format i.e using a 4k block. Moving to an advanced format of 4K sectors means about eight times less wasted space but will allow drives to devote twice as much space per block to error correction."We can put more data on the disk," he said. "It’s about 7-11% more efficient as a format."
One may think why should I bother about it. The reason is that except windows xp all operating systems including recent versions of linux and Mac os support 4k blocks. Does that mean the end of hard drives for Windows XP, currently the world’s top operating system? Not quite. Then plan is gracious enough to call for the 4 KB (4096 byte segment) to be aligned with the past 512 byte segment. So Windows XP users can still buy new drives and use them.
But the problem is with the performance .In some cases what took a single operation on older drives will take two operations due to an emulation layer needed to allow Windows XP to treat the new drive format like the old one. Overall, experts estimate users will take a 10 percent performance hit.
We all love windows xp for it’s unrivalled performance, but when we use newer hard disks the performance will be hit. Already stats indicate that windows 7 has hit 10% market share and xp is slowly loosing it’s share because most companies are upgrading to windows 7. So be ready to bid farewell to world’s most used operating system.
