What is DNS Cache and Why You Need To Clear It.

The DNS cache is a small database maintained by a computer. The database contains records of all recently accessed hostnames and IP addresses.

If the location of the web server changes before the entry in your DNS cache updates, you can no longer access the site.

If you encounter a large number of HTML 404 error codes, you may need to clear your DNS cache.

After you clear your DNS cache, your computer will query name servers for the new DNS information.

You can install Linux apps in Google Chromebook Now !

Google confirms Chromebooks will soon be able to run Linux apps

Chromebook Supports Linux

Developers will be able to write and publish code directly from their Chromebooks.

Google’s Chromebooks will soon be able to run Linux apps and execute Linux commands following the company’s recent announcement that Linux support is coming to Chrome OS. 

The company’s flagship Chromebook, the Pixelbook will be the first Chrome OS device to officially support Linux with support for other devices coming soon.

Developers will now be able to write code on Chromebooks using Linux and they will also be able to use Android Studio for Chrome OS to write, test and deploy Android apps all from one device. Until now, developers would have to rely on systems running either Windows, Mac or Linux to create code and software to run on Google’s platforms. 

Chrome OS director of product management Kan Liu explained how the company managed to implement Linux support on Chromebooks to VentureBeat, saying: 

“We put the Linux app environment within a security sandbox, running inside a virtual machine. We made sure the user experience is seamless to the user. Whether you use a web app, whether you are using an Android app, or whether you are using a Linux app, the window treatment and the way you launch the app from the launcher is the same.”    

Linux app support will be made available as a preview first, though this will initially only be on the Pixelbook and users that wish to try it out will have to switch to the Dev channel to do so.  

 

Eventually Google plans to bring this feature to all Chromebooks but users will have to enable it as it will not be turned on by default.
