How can you capture every aspect such as white balance, exposure, focus while running and pistol photography?

I am an amateur photographer living in Calcutta. While I like landscape and nature photography very much, I do not find the same inner satisfaction when I see my pictures while walking and the weapon situation. For example, when I think of a beautiful monument or fabulous landscape, I take time to disassemble my equipment, set up my tripod, optimize my camera menu, focus, and scientifically substantiate my exposure by looking at the histogram and balance the white balance and then make the long awaited shot. But in street or event photography, there is no scope. This is because the subject is gone when I am out in the street with the camera in my hands and just setting the exposure, let alone focus and fix the white balance. I've gotten very frustrated lately with getting good footage, but after that they look like a 5-year-old kid has a camera in his hand and literally wanders around on the street doing almost no photos, sometimes overexposed, sometimes underexposed, and the colors are warmer or cooler, but never perfect. I need some advice on that, because I want to improve and explore those other genres of photography as well.

gnome – How do I stop two from almost every running process?

How do I stop two of almost every ongoing process? Gnome seems to work twice. I found it because an error was displayed Failed to start server, Address already in use, (Bind Failed), I'm not sure what I did to cause this. Recently I had to run so that NoMachine could be displayed correctly when the monitor was not connected sudo init 2, Could it be related to that? How do I fix this?

Why are more and more websites running subscription models?

[No idea if this is the right community, please forgive if not]

More and more, I notice that websites are charging for subscription services, whereas many years ago most websites were probably free when less data was sent and received [at times of lower speed, etc.]. A special example is Youtube. Now they offer Youtube Premium while inconveniencing free users. Amazon makes less sense to me, as they will certainly be used to serving as a shopfront, but they have also introduced features like Amazon Prime.

Apart from the obvious – because who does not want to make a profit – why is that? I would like to get a glimpse of people who are familiar with such things, as I am only a user and can only guess.

ext4 – Is there any way to back up the file access and modification time before running e4defrag?

I have a folder with thousands of files sorted by modification date so I can continue where I left off. Recently, this hard drive has grown beyond the 90% mark and file system access has become so slow that the system crashes for a while.

While my primary hard drive is fast, the read speed for these files is 30 MB / s (Gnome Disks Benchmark). But it has never done that. So I chose e4defrag. It solved the problem, did not freeze anymore, but it messed up the directories sorted by change date.

Before I can clone this disk to a larger one and expand the partition, I know that I'll need e4defrag again. Is there a way to back up changed files and restore to e4defrag?

Sync – How do I automatically back up a file on my phone to my NAS running on my local network?

I have a NAS in use and can connect to it from my Linux computer (fstab):

 // /media/nas-backup cifs vers=1.0,username=***,password=***,auto,iocharset=utf8,gid=1000,uid=1000,file_mode=0777,dir_mode=0777 0 0

I want to set up an app that runs on my phone and backs up my photos and text messages daily when my phone is on my network. I think I can do a lot with Tasker. But when copying files I am not sure how to proceed. I've heard that Syncthing is good for Android but can not find documents to connect to a CIFS-enabled NAS.

How can I set up Syncthing (or another program) to connect to my NAS and backup files on a regular basis?

Unity – How to move an object while the animation is running?

I have added a jump animation with the character in unity and to move the character I have the following code:

if (Input.GetKeyDown(KeyCode.Space))

        transform.Translate(Vector3.forward * 1 * jumpSpeed);

But here the character first moves his position (like a glitch) and then does the animation. How can I realize it at the same time?
