How to download songs on Spotify to my computer
Recently , I found some great tracks on Spotify that I’d love to download and listen to offline on my computer. However, I’m not entirely sure how to go about this. When right click on the song, there is no DOWNLOAD option available.
I’ve heard that there are specific tools that can help with downloading songs on Spotify, but the suggestion from Google search is crap! I’m looking for a reliable and straightforward way to do it. Could anyone provide some guidance on how to download Spotify songs onto my computer?

Trying to report mail usage, internal vs externally sent messages
Hi,
I am trying to find a way that I can report per user per day the number of messages sent, split between internal or external. My company has a few different domains that we class as Internal, checked the 365 Admin > Reports section but nothing there appears to provide the breakdown.
Has anyone done this, if so, how exactly, don’t mind if PowerShell or GUI

Sync Emails with microsoft email to main organisation (for us NHS mail) email together?
Hi
I want to sync the Microsoft account with our organisation (NHS) email account, is this possible?
We need this to sync into the staffs calendars etc but if its linked with our Microsoft log in (which is a different email) we will need it to be sync. Or is there a way to forward/redirect emails to the NHS account?
We need it to be linked with the account as we do not have permissions etc in the NHS account (as says do not have access to create shared bookings but it is an option on the other Microsoft email account as there licence is linked with this). However this is not the main account we use and need this sync together. Please can i check this ASAP?
Thanks!!

How to include an image with original resolution in a Live Script?
I am creating an exercise for a course with a Live Script in Matlab 2016a.
I made some PNG drawings with free body diagrams. Unfortunately when they are inserted the Live Script, the image quality is dramatically decreased, making the text in the images very difficult to read.
I tried also TIFF and JPEG with the same results.
Is there a way to include an image in a Live Script with the original quality and resolution?
Where can I suggest the addition of support for SVG or some format that support vector images?

Unable to start MATLAB R2023a in Ubuntu Linux 23.04, it stops after “MATLAB is selecting SOFTWARE OPENGL rendering.” message
Hi there,
I’m trying to solve this problem for hours, yet I don’t have any solution. Looked through installation docs, but couldn’t find why the problem occurs. I installed MATLAB R2023a without a problem via the ISO file which my school gave me. When I try to run the matlab, "MATLAB is selecting SOFTWARE OPENGL rendering." message comes and after a second, process stops without an error(?). The program wouldn’t start either.
My gcc and g++ versions were 12, I downgraded them to 11 since its says the latest version it supports is 11 in Matlab docs. However it didn’t work.
I also tried
./matlab -nosoftwareopengl
this time the message I mentioned earlier doesn’t come up, but process again stops after a second.
I checked my system resources, my CPU usage increases for a second but memory usage stands still.
I installed two times into different locations to check if it’s about permissions or whatnot, but it didn’t help.
I tried other suggestions from this forum, but no help.
No solution yet.. I’d be happy if we can sort this out 🙁

802.11 Beacon Packet recovery failing
Hello Y’all,
I have a NI USRP coupled with a router’s antenna, and I receive 802.11 wifi signals in the 2.4G band. Then I convert that signal to .mat format and filter channel by channel to extract beacon frames and print their info such as ssid, bssid etc. I use Maltab’s WLAN Beacon Receiver Using Software-Defined Radio tutorial to do the beacon extraction, with config=’OFDM, band 2.4′ . I was able to see the router’s ssid from my phone and laptop, like how it is broadcasting in channel 1, 2.4 band (non-HT data) and its mode is 802.11n. I was also able to see regular spikes of energy every 100 ms when i plotted the spectrogram of channel_1 from the .mat file, indicating there is beacon transmission clearly. I am not able to figure out why the matlab code is not able to extract the beacon frames, i just used the standard matlab tutorial attached above, any help in figuring out the bottleneck in my approach would be really appreciated. Let me also attach the actual code in case if it helps (also my matlab version is R2022b)

tocHello Y’all,
I have a NI USRP coupled with a router’s antenna, and I receive 802.11 wifi signals in the 2.4G band. Then I convert that signal to .mat format and filter channel by channel to extract beacon frames and print their info such as ssid, bssid etc. I use Maltab’s WLAN Beacon Receiver Using Software-Defined Radio tutorial to do the beacon extraction, with config=’OFDM, band 2.4′ . I was able to see the router’s ssid from my phone and laptop, like how it is broadcasting in channel 1, 2.4 band (non-HT data) and its mode is 802.11n. I was also able to see regular spikes of energy every 100 ms when i plotted the spectrogram of channel_1 from the .mat file, indicating there is beacon transmission clearly. I am not able to figure out why the matlab code is not able to extract the beacon frames, i just used the standard matlab tutorial attached above, any help in figuring out the bottleneck in my approach would be really appreciated. Let me also attach the actual code in case if it helps (also my matlab version is R2022b)

A very useful update to support sharing links expiration for all link types used by SharePoint Online and OneDrive for Business is now rolling out and should be available in all Microsoft 365 tenants soon. Until now, expiration dates were only available for anyone links. Many organizations don’t allow anyone links, so enabling the feature for company-wide and specific people links will be much appreciated.

How to install Windows 11 without internet or network on a PC?
Hi everyone,
I’m planning to install Windows 11 on a PC, which only has cable connection. My home is a WiFI router. So this PC does not have Internet connection or any network during the installation process. I’ve heard it’s possible to install Windows 11 without Internet, but I’m not sure about the steps involved.
I understand that the typical installation process for Windows 11 often requires an internet connection, especially for the setup of a Microsoft account. Can someone guide me on how to install Windows 11 without network on a PC?

Windows 11 computers occasionally have black screens
My Windows screen will go completely black and unresponsive. It’s like the computer is stuck or frozen, but it’s not shutting down or restarting. The keyboard and mouse don’t work, and I can’t even get to the login screen. Sometimes I have to wait for a few minutes, and then the screen will flicker back to life and everything will be normal again. But other times, I have to restart my computer manually.
