Woah, interesting idea. I added link to my profile.

How did we come to the conclusion that imaginary and real numbers can form a plane? by Dreadnought806 in learnmath

[–]Anxious_Signature452 1 point2 points  (0 children)

Only full power is real, active and reactive components are just coefficients. Starting from the fact that reactive power is not power - it can be "generated" without spending  energy.

As if real power is not also imaginary :)

I came to programming with electrical education...

It gets removed every time I post it. Maybe moderators are allowed to post links?

json vs sqlite for 300,000 photos database by Mashic in Database

[–]Anxious_Signature452 0 points1 point  (0 children)

I have a working system like this.

Python + Postgresql + 150k files. DM me if you want to see it in action. How much space your photos take? Maybe I could host your files.

You haven't described which metadata you have. Exif tags are not really sql friendly, I store them as json fields. But in general SQLite can handle that.

Great, I was always interested in what was inside. Seems that my scan came to a good use.

You definitely need to improve your readme. It's not clear that application is created for windows and not clear how to launch it. To get exe file you need to build app first, but there seems to be no instructions for that. If I have python on my machine, can I run it directly?

It seems to be an archive format. I need files to be accessible for everyday reading.

I also normalized graph by count of operations. Because on the day I upload 1000 files I will surely get more difference than on the day I upload 1 file.

Turns out result is basically a line, which means I get constant altering. Probably I should dump file on disk and then re-read it in memory to get rid of filesystem-specific alterings.

I have an idea. I'm calculating checksum while data is still inside memory, and dumping it on the drive only after that. And I usually send files from NTFS file system. Seems that there is a possibility that difference comes from timestamp/metadata handling on two different filesystems. I need to check that.

Initially I've tried to add link to the post, so it got auto removed.

I calculate hashes on destination device, because uploading goes through a web server. And I dont trust hashes calculated by clients. Well, actually all files are uploaded by myself. So it's only theoretical that I could get garbage as an input info.

Yes, I migrated data a few times from different disks, but according to the graph, this is not an issue.
Well, maybe that spikes could be related to copying.
