Batch fixing corrupted JPG files? - jpeg

Ugh. So I went on a vacation in Indonesia and the photographer just sent (after 6 weeks) a USB with about 300 photos, each 6.5 or so MB large...and only FOUR open up into actual JPGs. EVERY OTHER IMAGE doesn't display a thumbnail and won't open -- I've tried renaming the files as JPGs, tried guessing if it's a png or gif and renaming them that way, tried dragging into Chrome (apparently a robust file viewer).
When I open with Image Viewer (I'm on Lubuntu 18.04LTS) I get an error:
"Not a JPEG file: starts with 0xff 0xff"
And when I use "file" I get this:
"ISO-8859 text, with very long lines and no line terminators"
Sooooo...that's why these aren't opening up. Unfortunately I can't reconnect with the driver so my ONLY hope in getting these vacation pics is to somehow bulk fix them. Even if it's painful. I don't have much hope but if anyone knows what's happened I would love to know if there's anything I can try. I am thinking doing some kind of hex editor might remove the initial tag and make it a JPG again??? The fact that they are the right size seems to make me think maybe it's just a small thing that has gotten borked here and maybe I could fix it manually.
As mentioned above, running Lubuntu 18.04LTS. Any help or thoughts would be great.

Garageband Save & Save As & Export Buttons Do Not Function

I recently started making music using GarageBand's MIDI software. I've made it up to a certain point, where losing all my progress would be disastrous.
Here's the issue I have:
When I go to File > Save/Save As or just cmd+S or cmd+shift+S, or Share > Export Song to Disk, instead of functioning and saving the file (I checked in Finder; last time I exited the app without saving due to this issue, the untitled garageband file disappeared) properly onto the app, it would either do nothing or give me the rainbow wheel of death for 10-20 seconds and then proceed to not function.
I've searched online for answers to this, and there were several (2) users I found that had the same problem. Their post either had no answer or the answer was unintuitive (such as always using a different, more complicated method to save, like messing around with the garageband files themselves everytime to save).
I'm looking for an answer to this issue that would result in slightly more convenient, one-time edits to the app / any software beneath that would fix this issue, if there are any. However, if the community has any alternate way to save the file right now, I would greatly appreciate it.
======
Also:
Since I'd assume most of the solutions would involve closing the app and then making edits, then reinstalling it, please tell me if I could just copy the notes (not the tracks) onto a text document and paste it into the new file after. I would prefer to save my music.
Try this . . .
First QUIT Garageband (yes you will lose unsaved work).
Find the Garageband folder where all the .BAND files are saved. Usually it is in Users -> Username -> Music -> Garageband.
Move older .band files into another folder (EG: "Garageband OLD")
Then start a new project (or open a project still in the Garageband folder).
Save and Save-As should now work.
It seems there is some sort of file limit for the Garageband folder. In my case the file limit is either 170 .band files or about 125GB.
I am currently using Garageband 10.3.5 on High Sierra.

Raw sound files editors, 8bit

I was wondering if anyone knows how to open and edit a raw sound file (raw unsigned 8-bit).
I am making my own game and trying to create original 8-bit music.
I could not open SoX, and all other editors I have cannot play these frequencies correctly.
I appreciate all help.
try using beep box. you can recover work from the past 30 days. or, you can try import a .mid file. you can have 4 base notes, and set the instrements to 8-bit sounds, crunches and waves. hope it works for you! --> beepbox.org or search it up if this link doesnt work

Is There a way to recover a severely corrupted EXCEL FILE?

I'm currently working on my data using Ms.Excel.
But suddenly the file that I'm working in was broken. when I tried to open it again I get error where it contain "ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ" (See Picture).
Screenshoot Corrupted Excel File
The data was not really big, it's only arround 130KB. Besides, Autorecovery Mode was Turned On every 10 minutes. But I don't know How To use it.
I tried to solve the problem many times using below method:
First, I tried to check the "Ignore .... " in Excel Option.
Second, I tried Open and Repair the file, but still can't open it.
Third, I tried to use a third party, Using 2 Software (Stellar Phoenix Excel Repair And Recovery Tools For Excel). but Both not Working.
So I wonder if anyone can help me to get my data back? is there any way to recover the file? or is there a way to get the data within the file?
Thank you for all the suggestion you gave me, From the last comment I tried to get and extract the data using Programmer editor and using VBA, but both not give a good result, basically when you tried to extract the data when the file is corrupted it only get a unique character.
So here is my solution, since i'm using windows, I tried to Reinstall my Ms.Office and recover my Excel file on mac, and boom the magic worked.
Once again, thanks for your help.

Recover corrupted file in notepad++

I had a text file to save all my important credentials, links and notes. Today when i was working on it, all of a sudden notepad++ crashed. when i reopened np++ the file was empty with zero bytes. I am so stuck now as it has all my credentials.
Is there a way to recover this?
Many thanks
Well you need to recover the file from your latest backup, but I'm guessing that because your asking this question, you don't have one?
If that's the case, then your pretty limited in what you can do. If you have saving of previous versions turned on in Windows you may be able to load an older version by right clicking on the file, go to properties and look at previous versions.
However, more than likely you are going to have to accept that it is gone, learn your lesson and start doing regular backups.

Issue in pdf to text depending on PDF file's version

I'm actually working on ubuntu as I'm trying to parse pdf files to extract text from them, which I managed to get working (using tesseract for example), BUT as I get a 1.7 pdf file version, conversion doesn't work (I get a blank page in my 'name.txt' file).
So I was wondering if anyone knew about some magic that can solve my problem regarding this pdf version issue...
I looked pretty much everywhere I could on the web, without seeing similar issues, therefore I came to y'all.
Hope you'll find a way to help me, cause google hasn't been such a friend so far...
