    Item Feedback:


    The Specter and Meltdown bugs have forced companies to run for cover to fix hardware bugs that have affected all devices made in recent years. Google, Microsoft and Apple (just to name the larger companies) have released updates to "patch" and make the two bugs harmless.

    Also regarding Chrome, Google has released a new version (number 63) that allows you to use computers, smartphones and tablets without the fear of being attacked by hackers. In the new version of the browser there is the function "Site Isolation"which allows you to manage each open tab with a different process. In this way, if an open page closes inadvertently, you can still continue to use Chrome. A very similar system is the one already present on the browser, even if it works very slightly different.



    What is Site Isolation

    Chrome is a browser that uses a lot system resources Of computer. And the reason is quite simple: every single page uses a single process. This system always works, except if a tab is opened via a link on another page (for example when we click on a URL present in an e-mail or an article from the home page of a newspaper): in this case the two windows share the same process. With the Site Isolation function change the management of the pages opened through the links: they will not share the same process with the "mother" board, but a new one will be created. This will cause Chrome to use more PC system resources: it is calculated that the RAM will be occupied for a further 10-20%.



    How to activate Site Isolation

    For the moment the function is still in beta and to activate it you need to enter the section "Experiments"of Chrome. To do this you need to type in the address bar the string" chrome: // flags ". In the new window that will open you will have to press the keys Ctrl + F and search for the term Site Isolation. At this point the functionality should appear Strict Site Isolation. By pressing the Enable button, the Site Isolation will start working (it will be necessary to restart the browser).



    What Site Isolation protects us from

    La Site Isolation is one of the many tools that Google is working on to protect devices from Specter and Meltdown. Even if it degrades the performance of our devices, it is highly recommended to install it.
