All Teams Recordings to go to a designated Sharepoint folder

I am aware of the recent change to how Teams stores recorded meetings.

Is there anything we can do so instead of having group meetings recordings being stored in the Personal OneDrive for Business (under “Recordings”) to have them just stored in a folder in SharePoint?

At the moment its a manual job to move them I was hoping there is something a bit more automated to get them into SharePoint.
I have setup a recurring PowerAutomate Flow (https://powerusers.microsoft.com/t5/Building-Flows/Move-files-in-folder-from-OneDrive-to-Sharepoint-into-a-newly/td-p/673833#) to do it, but this ONLY works for me.

Any ideas or insight will be appreciated.

timestamp – Plausible way to alter time stamp on cctv recordings

I’m writing a screenplay (just a spec script – not for money (yet)). I need to write a scene realistically enough so it doesn’t seem stupid. A little jargon is useful. It may be impossible, but here’s what needs to happen.

Criminals need to edit out 47 seconds of cctv recording. The cctv footage is from a system (can be any system) that is in a small motel. They edit two sections – person walking in and later walking out of motel. The whole recording the police later seize is over 14 hours long. They need to edit out 47 seconds without it being completely obvious. There does need to be a flaw, but not easily discovered. The 14 hour tape looks fine to law enforcement – but it’s off. Any time stamp just needs to not match actual time.

The criminals would have had total access to the control room/motel system. They have total, unlimited access to admin privileges.

How could that plausibly be done?

data recovery – Exporting call records with phone call recordings from Mega Call Recorder Advanced app

This is a long-shot, but I really hope someone can help.

I was using the Mega Call Recorder Advanced Android app to record phone calls for quite some time. Its official package name was com.callrecorder.procallrecorder and the developer’s name was MEGA Clip.

Although I still have the app installed, it disappeared from the Play Store a while back. I’m not sure why, as it worked quite well. I did notice that its UI is very similar to many other call recording apps, and so I wonder if perhaps it was based on another project.

At this point, I have many GB of recorded calls stored by this now-defunct app. The calls are stored in standard MP3 format, and the filename of each is the timestamp of the call. So far so good. The big issue is that the filenames do not indicate the phone number (or contact name) of the caller / call recipient. That data is visible in the app’s UI, but I don’t see any export function.

I want to backup all of this app’s data and have the backups in a usable format. To do that, I need to somehow have a record of which contact (or at least phone number) each recording is associated with. Ideally, I would like the MP3 filenames themselves to include that essential information.

I’m hoping someone will have a good idea of how to proceed, or perhaps recognize the UI and know of another app that can perhaps export the data.

server – Do developers watch player match recordings for their online games?

When developers plan and decide on new buffs and nerfs, do they gather information from online game matches, recorded secretly from their servers’ data feeds and reconstructed / analyzed offline – for such data as player movement trajectories and popular paths, weapon preferences and gamestyle behaviour?

How to design a relational data model for music recordings?

In 1970, Edgar Codd published his seminal paper “A Relational Model of Data for Large Shared Data Banks” where he defined relational databases as well as their normalization to first normal form (1NF) in section 1.4, page 381. It is a procedure for eliminating non-simple domains (domains whose elements are relations) of a collection of relations in order to allow a simple two-dimensional array representation without pointers.

First normal form.

I have applied this normalization procedure to the following variants of collection of relations modeling music recordings.

Variant 1

  • Unnormalized relations (non-simple domain interrelationships: artist > album > song):
artist (artist_id, artist_name, album)
album (album_id, album_title, album_date, song)
song (song_id, song_title)
  • Normalized relations (1NF):
artist (artist_id, artist_name)
album (artist_id, album_id, album_title, album_date)
song (artist_id, album_id, song_id, song_title)

Variant 2

  • Unnormalized relations (non-simple domain interrelationships: artist > song > album):
artist (artist_id, artist_name, song)
song (song_id, song_title, album)
album (album_id, album_title, album_date)
  • Normalized relations (1NF):
artist (artist_id, artist_name)
song (artist_id, song_id, song_title)
album (artist_id, song_id, album_id, album_title, album_date)

Variant 3

  • Unnormalized relations (non-simple domain interrelationships: album > artist > song):
album (album_id, album_title, album_date, artist)
artist (artist_id, artist_name, song)
song (song_id, song_title)
  • Normalized relations (1NF):
album (album_id, album_title, album_date)
artist (album_id, artist_id, artist_name)
song (album_id, artist_id, song_id, song_title)

Variant 4

  • Unnormalized relations (non-simple domain interrelationships: album > song > artist):
album (album_id, album_title, album_date, song)
song (song_id, song_title, artist)
artist (artist_id, artist_name)
  • Normalized relations (1NF):
album (album_id, album_title, album_date)
song (album_id, song_id, song_title)
artist (album_id, song_id, artist_id, artist_name)

Variant 5

  • Unnormalized relations (non-simple domain interrelationships: song > artist > album):
song (song_id, song_title, artist)
artist (artist_id, artist_name, album)
album (album_id, album_title, album_date)
  • Normalized relations (1NF):
song (song_id, song_title)
artist (song_id, artist_id, artist_name)
album (song_id, artist_id, album_id, album_title, album_date)

Variant 6

  • Unnormalized relations (non-simple domain interrelationships: song > album > artist):
song (song_id, song_title, album)
album (album_id, album_title, album_date, artist)
artist (artist_id, artist_name)
  • Normalized relations (1NF):
song (song_id, song_title)
album (song_id, album_id, album_title, album_date)
artist (song_id, album_id, artist_id, artist_name)

Which of these variants of collection of relations makes more sense?

computer architecture – Types of recordings on magnetic disks

is my searching about the types correct?

Types of recordings on magnetic disks

Write: The current which goes through the coil produces magnetic field and then the pulses are sent to the head which produce magnetic pattern recorded on the surface.
Read: There are 2 ways (Traditional: In this method the magnetic field move relative to coil produces current and coil is the same for read and write.)
(Contemporary: Separate read head, close to write head, partially shielded magneto resistive (MR) sensor, electrical resistance depends on direction of magnetic field, High frequency operation, Higher storage density and speed)

Troubleshooting – Minolta XE-7 recordings Ilford Delta 400 B&W 35mm. The film came out clear, apart from about 5 decent exposures

I just bought a Minolta xe-7, shot my first roll and developed it at home. The result was a film reel that, except for the fist, had several exposures on the reel and a few white spots here and there almost completely clear. The film has marginal markings indicating that the development process was OK and everything I can find to indicate a camera issue. However, I tested the camera before and after loading the film and the shutter opens and closes properly, and I had no problems pushing the film forward while recording. The safe load indicator moved as it should and the frame counter moved correctly and stopped when I reached the end of the roll. So far I can not find a satisfactory answer, so I hope that someone can help me here. Thank you so much!

Media player – audio player for transcribing / recording recordings

I'm looking for a MacOS audio player that allows me to listen to my recorded meetings and take notes at the same time.

The player should

  • Supports global hotkeys (without the app being in the foreground) to rewind, pause, and play back a few seconds
  • Allow you to set the game speed (e.g. 1.5x)

I have already tried different solutions: VLC, iTunes, QuickTime. But none of them met all of my requirements.

I am currently using otranscribe.com, which is tedious to use because it only supports some very basic formatting (e.g. no bullets) in the text section. Since I use GoogleDocs, I always jump between tabs.

Do you have any suggestions? A free solution would be nice, but I'm also open to paid / commercial solutions.

Cleaning – sensor stain / dust test – should test recordings be exposed to the right?

I recently bought a new camera and did some sensor spot / dust tests. In some websites / instructions / videos, in addition to the usual setup (ISO 100, F / 22, focus on infinity, recording on a blank white wall, etc.), it is expressly mentioned that the shutter speed should be set so long that the das histogram would shifted to the right as far as possible without cropping. Nothing else is mentioned in this regard.

So I tried both. A test shot with the shutter speed set by the camera produced a gray image with the histogram mainly in the middle. Another test recording with a sufficiently long shutter speed resulted in a white image with the histogram mainly on the right. I did this several times and found that the gray test shots always contained more spots than the white ones (again, the histogram does not indicate that clipping has occurred).

I'm curious to see why. I assumed that the number of points in the image was the same for both test shots. Is it really necessary for these samples to be exposed to the law?
