mojave – Is it a MacOS normal behavior to switch between desktops slower while in Mission Control mode?

This is more of a performance issue than anything else.

Bringing up Mission Control is already a pretty complex split-second animation for your Mac to handle, especially if you have several windows open in your current desktop.

And if you have multiple desktops with several windows open, it has to render all the windows, grouped by application per desktop, and give them a different effect than usual (drop shadows are applied on the window group rather than individual windows in Mission Control) and so on.

Basically, it’s a more complex task for your Mac to do, and since you’re on Mojave, system UI is largely Metal, so if you have an nVidia chip or older intel graphics with no Metal 2 support, unfortunately it will feel like molasses.

The only solution would be to upgrade your hardware, or turn off the special effects by going to System Preferences -> Accessibility -> Display then checking reduce motion, reduce transparency, either one or both, depending on what you are willing to give up and how much of an improvement checking the options yield.

Make the Windows taskbar show / access windows on different desktops?

The default behavior of the Windows 10 taskbar when multiple desktops are used is to display only open programs on the current desktop. Is there a way to show all programs on the taskbar, and to make it so by clicking on a program running on another desktop changes desktop instead of opening a new window?

mojave – macOS: browsing between desktops using keyboard shortcuts

Go to the application System Preferences → Keyboard → Shortcuts and you can assign keyboard shortcuts to move through spaces (offices).

You can also use the F3 (Mission Control) on your Mac's keyboard to get a bird's eye view of all spaces (Mac desktop computers) and quickly and directly switch to the desired space. However, this will also involve the use of the mouse / trackpad.

If you are looking for a third-party tool to customize keyboard shortcuts with much finer grain control, Karabiner is a very popular application for macOS users.

gnome – Ubuntu 18.04, problem with headless desktops and remote access

I have an Ubuntu 18.04.1 LTS desktop installation that I use as Tor Relay. It uses a mini-PC with an Intel j4105 processor (integrated graphics).

I wish it was not connected via HDMI, because I do not have enough ports to connect it 24/7. When connecting via remote desktop tools, the Gnome desktop is buggy and is not really usable. Finally, I need to connect HDMI, disconnect the user, and then reconnect for it to work properly again. I read that it was not about being connected to a monitor. I've tried to install X11 emulator drivers on Ubuntu to be able to connect to a virtual desktop, but I could not boot completely (this would remain stuck on the purple boot screen ). So I reinstalled and bought a $ 7 HDMI dummy connector "Out of Amazon, a 1080p monitor is connected, but the problem persists.

Here is what happens when you are logged in with the help of NoMachine. The same thing happens with any remote desktop tool such as TeamViewer. (none of the icons / buttons on the desktop or toolbars are clickable)

thank you,

What did Stack members find to be the most useful apps for syncing Mac desktops?

I've used Chronosync in the past and everything was fine, but there are now many solutions (including, with effort, iCloud sharing).

What applications did YOU find most useful (including ease of use)?

Can we avoid third-party trust in mobile wallets / desktops for Lightning network channels?

Mobile and desktop wallets are nodes that are not connected 24/7 (when the application is closed, the computer is off, etc.).

The fact that they are not connected 24/7 is a major problem: if a fraudulent node closes a channel with you and sends an obsolete CSV transaction, you will not be able to see it and will not be able to invalidate it. in time if you do not do it. launch your wallet periodically.

One solution to this problem is to send all your CSV transactions to a service (connected 24 hours a day, 7 days a week to the blockchain) and to trust it enough to broadcast these transactions in case a fraudulent node decides to close the transaction. One of your channels.

And you really have to trust this service, because if it is affiliated with the fraudulent node, you must send it a higher fee than the value of the transaction or prefer to keep the fraudulent transaction.

The conclusion is that you can not trust such a service.

Is there another way to avoid trusting a third party in such a case?


One solution found by the Flash Lightning Wallet for Android is to prohibit relaying or receiving payments (ie you can only send payments). In this way, an obsolete transaction is always detrimental to the fraudulent node. This is obviously not satisfactory if you want all the features of the Lightning network.

Windows 10 – Switch between virtual desktops with and without VPN: do I need a virtual machine for this?

On a Windows 10 computer, I would like to use my university's virtual private network to navigate school content, while using the Internet connection without a virtual private network (VPN) for unrelated pages (this is ie when I'm connected to a VLAN, which turns me off as soon as I change to another VPN for security reasons). A useful feature that I find useful to use is Windows Virtual Desktops, which allows seamless switching between workspaces. However, the activation of VPN on a virtual desktop works naturally for others. I would like to somehow separate these two workspaces, but with the possibility of an easy switch between them.

My idea as a workaround would run a virtual machine on another virtual desktop in full screen, where inside the virtual machine I would connect to the VPN. If I imagine it correctly, it should not be transmitted to the host machine.

My question: Is such an approach legitimate or are there better approaches (with, I hope, less overhead) for such a configuration?
