Google-page-speed-service

Google Page Speed service is the Google’s answer to Cloudflare and I have decided to give it a try on this blog to see how it works and if it makes my site faster. Normally I’m not much in to CDN’s because I could gain similar performance for less cost by using an tuned nginx setup for static content delivery. However CDN’s will be handy if you need to store lots of files. I’m managing a large social network and on there I use Amazon S3 and Cloudfront CDN for content delivery. Handling a large number of small files such as user photos and thumbnails is a worrying task and Cloud comes to rescue there. I don’t use CDN’s for this blog or any other regular web sites that I have. Just for the sake of experimenting I have tried Google Page Speed Service.

GPSS is still at beta stage and you need an invitation to get in. You can request an invitation here and you will probably receive one in few days if your site is eligible. Setting up GPSS is really is just like Cloudflare. You just have to set a CNAME record for WWW pointing at “pagespeed.googlehosted.com”.

Like shown on the screenshot above GPSS works by sitting on the middle of your server and end users. GPSS servers cache the images and other scripts to deliver it quickly to the users. And there are many other advanced optimization techniques are used on it. [click to continue…]

Galaxy Tab 8.0 and 7.0 also gets the refreshment and Galaxy Tab 8.0 ($299) packs Exynos 1.5Ghz dual core processor, 1.5GB RAM, Android 4.2, 1280*800 display and Galaxy Tab 7.0 ($199) includes 1.2Ghz dual core processor, 8GB of storage and 1024*600 LCD display.

See there’s nothing new on those models except they are called Galaxy Tab 3 series. Last years specs and nothing surprising than the original Galaxy Tab models. While Samsung likes to include cutting edge hardware on its Phones and the phablets like Galaxy Note, it certainly seems like they have stopped doing same on their tablet line.  [click to continue…]

You just need to click the “Get a free server” button and you will get the login details to your VPS instantly like shown on the screenshot above. As you can see that window also displays the time period on the bottom right and after the time is up, your data will be terminated. To keep it longer you have to pay them [click to continue…]

instagram-video
Vine has gained lots of loyal users since it started just few months ago. Vine isn’t really a ground braking concept but surprisingly its now used by many users worldwide. Personally I think 6 seconds isn’t enough for a video. Instagram has definitely felt the need to do something like Vine and today it launched its own 15 second video sharing option.

Android and IOS app update is already available to download and other than the video sharing feature, the interface hasn’t changed much. Surprisingly you cant view videos full screen. As you know same applies for the Instagram photos so I doubt that this will get solved anytime soon. Video is something that I would like to view full screen. Instagram video has 13 filters available and it looks really nice. However your videos will need little bit of time to process depending on the performance of your smartphone. [click to continue…]

google-panda

Google Panda algorithm update mainly targets content farming techniques. For a moment forget about the content you stolen from other web sites. Do you know that your own content can affect your rankings because of misconfigurations of your script? For example if you run WordPress web site like I do, sometimes it exposes duplicate pages to google bot. /?replytocom , /?comments=true are a major headache to webmasters. You can check if your site has the same problem by searching this on Google

site:ruchirablog.com inurl:replytocom

That will show all indexed pages with /?replytocom links. This severely affects your Google rankings because duplicates of same page will be indexed on Google search such as /abc , /abc/?replytocom , /abc/?comments=true

If you are using a SEO plugin like WordPress SEO you can set it not to index these links but if you already got those indexed, there is a way to remove this from Google Search. [click to continue…]

PlayStation 4 Hardware analysis and Price

by Ruchira on June 11, 2013

playstation-4

Sony just announced the PlayStation 4 few hours ago at the E3 conference 2013. I think it looks more appealing than the Xbox One and hardware wise there aren’t any huge improvements like PS3 had when comparing with PS2 but its acceptable. PS3 still handles  great graphics without a glitch and PS4 is certainly has better hardware. PlayStation 3’s “Reality synthesizer” GPU delivered about 400 Gigaflops and PS4 GPU said to have 18 compute units and 1.84 Gigaflops of performance. So its about 450% times powerful than the PS3’s GPU.

PS4 features an AMD Jaguar architecture based X64 APU ( Accelerated Processing Unit )  which incorporates CPU , GPU and also the memory controller on to a single chip package. Clock speed of the processor will be about 2Ghz but information about that is still unclear. Xbox One also features same processing architecture so this will make developers somewhat easier to support both platforms. PS4 takes lead in the RAM department because it features 8GB of GDDR5 RAM whereas Xbox One got GDDR3. Sure GDDR5 has advantages when thinking about the memory bandwidth but it has more latency when comparing with GDDR3, So don’t expect PS4 to be so much faster than the Xbox just because of the RAM. But its really nice to see Sony went with GDDR5 technology.  [click to continue…]

facebook

Have you ever wanted to view someones privacy protected Facebook profile pictures?
