VARNISH MAKES WEBSITES FLY!!

Varnish is a web accelerator written with performance and flexibility in mind. Its modern architecture Gives it a significantly better performance than competing solutions. Varnish stores web pages in memory so web servers do not have to create the same web page over and over again. Varnish Cache serves pages much faster than any application server; giving the website a significant speed up.

Varnish Software

Varnish is an HTTP accelerator designed for content-heavy dynamic web sites. In contrast to other HTTP accelerators, such as squid, which began life as a client side cache, or Apache, which is mainly the origin server, Varnish was designed from the ground up as an HTTP accelerator. The project was initiated by the online branch of the Norwegian tabloid newspaper Verdens Gang. The architect and lead developer is an independent consultant Denmark Poul-Henning Kamp (known FreeBSD core developers), with management, infrastructure and additional development originally provided by Norwegian Linux consulting firm Linpro. Support, management and development Varnish later spun off into separate companies, Software Varnish.
Varnish is an open source, available under the two-clause BSD license. Varnish store data in virtual memory and leave the task of deciding what is stored in memory and what will be paged out to disk for the operating system. This helps avoid situations in which the operating system starts caching data to disk while they move with the application.

Moreover, Varnish is highly threaded, with each client connection is handled by a separate worker thread. When configured limit on the number of active worker threads is reached, incoming connections are placed in a queue overflow; only when the queue reaches its limit will be configured for incoming connections rejected.
The main configuration mechanism is VCL (Varnish Configuration Language), a domain-specific language (DSL) which is used for writing hooks that are called critical points in the handling of each request. Most policy decisions are left to the VCL code, make Varnish is much more configurable and adaptable than most other HTTP accelerators. When the script is loaded VCL, it is translated into C, compiled into a shared object by the compiler system, and is directly connected to the gas pedal.
A number of run-time parameter control such things as maximum and minimum number of worker threads, timeout etc. various command-line management interface allows these parameters to be changed, and new VCL scripts to be compiled, loaded and activated, without restarting the accelerator.
In order to reduce the number of calls in a fast-track system to a minimum, the log data is stored in shared memory, and task filtering, formatting and writing log data to disk is delegated to a separate application.

And the fact that facebook is one of the software that supports the facebook for photos or video content. Facebook uses Varnish to serve the photos and profile pictures,handling billions of requests every day.

Ice Cream Sandwich is the latest version of the Android family planned for release in the fourth kukartal 2011. Told by Google's top brass, Mike Cleron, Ice Cream Sandwiches are the most ambitious project from Google. So what can you be in the Ice Cream Sandwich?

Androidandme site gives 13 predictions about the Ice Cream Sandwich by all the rumors that have circulated. Please look at emergency at a time and please specify which points are likely to materialize when the release of Ice Cream Sandwich later.

1. One OS for all
The main problem faced by application developers for Android is fragmentation. As is known smartphones, tablets, and Google TV has a different version of Android, so developers have to work hard to adapt to the applications they create. While Google has been taught how to create applications for a variety of screen sizes, but the problem that arises then is when uploading different versions of the application to a variety of different Android devices.

For that Mike Cleron said that the purpose of the Ice Cream Sandwich is to provide convenience to the developers in creating their applications.

2. UI updated
Although not yet known appearance of the Ice Cream Sandwich, but speculation is growing so sure that it would be a Holographic development of the new UI released at the Google I / O a few months ago. Surely with the new launcher, multitasking UI, widgets Richer and more recent aplication.

Others say that the Ice Cream Sandwich Android phone will be made without capacitive buttons and replaced by on screen navigation buttons such as the Honeycomb on the tablets.

3. Truly Open Source
Google plans to enter the Ice Cream Sandwiches on the Android Open Source Project. Of course this is good news especially for those of you who like using a custom ROM. Andy Rubin said that his company wants to prevent developers to incorporate Android mobile software on the user experience which often leads to really bad.

4. Android 4.0
Google so far does not mention the version number of the Ice Cream Sandwich until the eve of its release later. But you can bet that this ambitious project will be called as Android 4.0. Because unlike the previous version so it seems unlikely Google will use the version number 3.x

5. Linux 3.0 kernel
Linus Torvalds announced the latest update from Linux on 21 July. Chance of Ice Cream Sandwiches will use the latest version, the Linux 3.0 Kernel.

6. Android Market to provide music
Android lovers must have long hoped the Android Market can provide a digital song sales. But until now there has been also realized. The latest leaked contains icons for the music store are believed to be part of Google's plan to prepare for Android Music Store, it can even be launched before the release of Ice Cream Sandwich.

7. Multi-core processors in smartphones
Android 2.x can support multi-core processors, but not optimal. Android 3.0 is the first version that can run either on single-core processors and multi-core processors. And Android 4.0 will complement all that well on the tablet and for smartphones.

8. 1.8 x faster than Honeycomb?
Androidandme sources told that the Ice Cream Sandwich speed higher than 1.8 x Honeycomb. But because there is no detailed information, it is not known whether increased speed is there in your browser, or overall performance GPU.

9. Integration of Google TV and Chrome OS with smart docks
What may be developed by Google is like what has made Motorola a smart strategy dock. Later if you connecting Android phone to a television then you'll get features such as TV or sperti Google Chrome OS.

10. Theme engines for OEM official
Google is currently said to be working on an engine officicial theme chosen for number of manufacturers. Go Launcher EX you can find in the Android Market is said to be one part of that theme.

11. Competing with Apple's Game Center
OpenFeint and Scoreloop is a social gaming network, but Google's Android not yet have an official game center that could be used to compete with Apple. Reportedly Games Google services will be provided, and as a first step has diberikand Google + i.

12. Support Android phone available today
At the recent Google I / OI Android team asked if the Ice Cream Sandwich require special requirements to hardware so it can not run on Android phones that have been circulating on the market today. Although it does not mention one of the phones but Google indicates that a phone with Android 2.3 will be updated to Android Ice Cream Sandwich.

13. New camera tricks, virtual camera operator
Android Ice Cream Sandwich will have many features of the API developers included some cool camera tricks. Even if you recall, Google has to show it on Google I / O.
