How to install Signal Desktop on Linux

Signal is published by the Signal Foundation and Signal Messenger LLC. These two not-for-profit organizations—based in Mountain View, California—were founded by Matthew Rosenfeld (aka ‘Moxie Marlinspike’) and Brian Acton. Together they continue the work started at Open Whisper Systems, one of Rosenfeld’s earlier start-ups.

The Signal application is free and open source. Anyone can review the source code. The source code for the Signal Messenging Protocol (SMP) was reviewed by a joint team from the German CISPA Helmholtz Center for Information Security, the Swiss ETH Zurich University, Cisco, and the Canadian University of Waterloo. They declared the code clean, the motives pure, and the encryption rock-solid. Signal is definitely secure.

How to use Linux’s screen Command

The Linux screen command is a versatile tool that allows you to run terminal applications in the background and switch back to them when needed. It supports split-screen displays and can be used over SSH connections, even after disconnecting and reconnecting. With screen, you can create new windows, run multiple processes, detach and reattach sessions, and share sessions between multiple users in real-time.

With the Linux screen command, you can push running terminal applications to the background and pull them forward when you want to see them. It also supports split-screen displays and works over SSH connections, even after you disconnect and reconnect!

What Is the screen Command?

The screen command is a terminal multiplexer, and it’s absolutely packed with options. To say it can do a lot is the granddaddy of understatements. The man page runs to over 4,100 lines.

The following are the most common cases in which you would use the screen command, and we’ll cover these further in this article:

  • The standard operation is to create a new window with a shell in it, run a command, and then push the window to the background (called “detaching”). When you want to see how your process is doing, you can pull the window to the foreground again (“reattach”) and use it again. This is great for long processes you don’t want to accidentally terminate by closing the terminal window.
  • Once you’ve got a screen session running, you can create new windows and run other processes in them. You can easily hop between windows to monitor their progress. You can also split your terminal window into vertical or horizontal regions, and display your various screen windows in one window.
  • You can connect to a remote machine, start a screen session, and launch a process. You can disconnect from the remote host, reconnect, and your process will still be running.
  • You can share a screen session between two different SSH connections so two people can see the same thing, in real-time.

Connect your Excel workbook from OneDrive for work or school to Power BI

When you choose Connect, your workbook appears in Power BI just like it would in Excel Online. However, unlike Excel Online, you have some great features to help you pin elements from your worksheets right to your dashboards.

You can’t edit your workbook in Power BI, but if you need to make some changes, you can select Edit from the Workbooks tab of your workspace. Then choose to edit your workbook in Excel Online or open it in Excel on your computer. Any changes you make are saved to the workbook on OneDrive.

Create a copy of a dashboard in the Power BI service

There are many different reasons to make a copy of a dashboard. Maybe you want to make changes and test its performance against the original; or create slightly different versions to distribute by colleague, region, or team. Perhaps a colleague admires your dashboard design and wants to use it for reporting out to their managers. Another reason would be if you have a new database with the same data structure and data types and want to reuse the dashboard you’ve already created. This can be done but would require work in Power BI Desktop.

Dashboards are created and copied using the Power BI service and can be viewed in Power BI mobile and Power BI Embedded. Dashboards aren’t available in Power BI Desktop.
