I generally prefer to send emails via Google Workspace, if necessary using sSMTP, but in case someone needs to use phpmailer and send out emails, phpmailer also makes DKIM signing relatively easy.

A couple of days ago, when I attempted to shut down Linux Mint 20.3 on the Macbook, there was no shut-down button visible on the usual shut-down dialog box. I thought this was some problem with the latest update, and thought that a restart would fix things. (That was a mistake, as you can see below). But after doing a sudo reboot from a terminal, the system would not boot up - it complained of a kernel panic, no working init found, and suggested trying to remove the init options. After googling some no working init found forum posts etc, thought I might need to check the disk for errors, but
badblocks /dev/sda3
found no errors. Then I thought I would just try booting with another kernel - pressed F2 (more options) from reFind, booted with an older kernel 5.4.0-121-generic. Booted up with no issues. Tried doing
sudo apt update
sudo apt upgrade
Then found the real culprit.
E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem. $ sudo dpkg --configure -a
Setting up linux-image-5.15.0-41-generic (5.15.0-41.44~20.04.1) ...
Ah - so I was the culprit - Mint was not showing the shutdown button because the update was still in progress - I had somehow interrupted it. Anyway - running dpkg manually with the command above fixed the issue, and the system boots fine now with the 5.15.0-41-generic kernel too.
There seemed to be some issues like Chrome and Edge (on Windows) not connecting to localhost, as mentioned at https://stackoverflow.com/questions/43889497/chrome-cannot-connect-to-http-localhost8080-but-http-127-0-0-18080-works
So, I just changed the SSH tunnel to port 8080, and used the url like http://127.0.0.1:8080/restOfURL for it to work.

Ac purchased a brand new Dell laptop pre-loaded with Ubuntu, Dell Latitude 3410. After he booted it up and finished the setup with his login, when he tried the headphone jack, it did not work. The sound stopped coming out of the speakers, but no sound from the headphones.
At first, I wondered if it was a hardware fault. Then found that this is a known problem with these laptops as seen on Dell's help forum -
https://www.dell.com/community/Latitude/Latitude-3410-and-3510-Audio-Jack-Problem/td-p/7659856
Since the above solution, of installing the Dell Optimizer app, is for Windows, googling for help on Linux, found these two posts.

This second one worked - the solution was to comment out the line which automatically suspends "sinks/sources that become idle for too long"
in /etc/pulse/default.pa
### Automatically suspend sinks/sources that become idle for too long
#load-module module-suspend-on-idle
And then reboot. After the reboot, manually choosing the audio as headset and manually disabling the speakers output using the pulseaudio sound control app gives us the desired outcome.
After the Income Tax department (India) have changed to their new income tax e-filing portal last year, there were some teething troubles, but this year things seem to go smoothly. Or perhaps it is because I have learnt last year's lesson and did the first submission using the offline utility instead of online, since last year the offline utility was more stable than the online software. Or maybe because their documentation, help and faq sections are pretty good. Some notes, in no particular order.
We had an iframe with a blogspot blog being displayed on the website. But the iframe content was too wide, there were horizontal scroll-bars on the iframe. Looking for solutions to resize the content, this answer scales it by half, and this answer has support for more browsers. I used the latter, but without the pos. So,
....
<head>
....
<link rel="stylesheet" type="text/css" href="../../css/iframe-for-blog.css" />
....
</head>
and in the iframe-for-blog css file,
iframe {
| /* Set the width of the iframe the size you want to transform it FROM */ |
| width: 1108px; |
| height: 710px; |
| /* apply the transform */ |
| -webkit-transform:scale(0.75); |
| -moz-transform:scale(0.75); |
| -o-transform:scale(0.75); |
| transform:scale(0.75); |
| /* position it, as if it was the original size |
| position: absolute; - we're not using this. |
