How to setup a ZFS storage pool Ubuntu 16.04

Overview

ZFS is a combined file system and logical volume manager originally designed and implemented by a team at Sun Microsystems led by Jeff Bonwick and Matthew Ahrens. Features of ZFS include protection against data corruption, high storage capacity (256 ZiB), snapshots and copy-on-write clones and continuous integrity checking to name but a few. If you are dealing with large amounts of data, or providing a backing filesystem for virtualisation, ZFS is a great choice.This guide will go through the process of installing ZFS on Ubuntu 16.04 LTS and setting up a storage pool.

Cum sa adaugi un QR code in Power Point folosind QR4Office

QR code este o solutie foarte simpla de a partaja ce informatie dorim, cum ar fi un anumit website, numar de telefon, punct geografic. Spre exemplu, pentru a nu tasta un link mare catre o pagina web putem crea un QR code care va fi scanat cu telefonul si va intra automat pe acea pagina. In Power Point ne este util cand vrem ca ceilalti sa aiba acces la un website spre exemplu, fara a mai fi nevoie ca fiecare sa isi noteze link-ul.

How to Remove Contacts From the Share Sheet on iPhone or iPad

The Contacts row in the Share sheet on an iPhone.

The iOS 13 and iPadOS 13 updates brought a redesigned Share sheet to iPhone and iPad. Unfortunately, the new dynamic contact shortcuts can be annoying. Here’s how you can remove them from the Share sheet.

The first row in the new Share sheet serves as a shortcut to quickly sharing something with recently-used contacts. In theory, it’s supposed to make your life easier. In practice, however, it rarely works out that way.

Right now, only contacts from AirDrop and Messages appear in this list (sorry, WhatsApp lovers).

If you rarely (or never) use the feature, it can get annoying quickly. Unfortunately, you can’t disable the contacts row, but there is a work-around. If you delete a conversation or group thread from the Messages app, it disappears from the Share sheet, as well.

This step is a bit severe, but if you want to remove a contact from the Share sheet, this is the only way. To get started, open the “Messages” app on your iPhone or iPad. Find the conversation you want to remove in the Share sheet.

How to Enable and Use Tab Groups in Google Chrome

Group Tabs example image

Are too many tabs cluttering up your Chrome browser? Google’s working on a solution to help organize all the tabs you have open. The Tab Groups feature provides neat, color-coded labeling for all your tabs. It’s available today behind a flag.

Warning: This feature is behind an experimental flag, which means Google’s developers are still working on it. Like Google Chrome’s Clipboard sharing feature, it may be buggy, or it may change dramatically in the future. It may even be removed in a future update. We tested this feature in Google Chrome 80.
