Laptop running as a server

I am running an old Dell Laptop as a server with Ubuntu 18.04 on it. Installing Ubuntu on the system was straight forward, but at a certain point you want to close the lid of the laptop. This puts your laptop in sleep, which for a server is not the intended result.

Disable Sleep on Lid Close

So, it has been an interesting journey, but time to remove git-lfs. Here follows a summary of the approach I used to safely remove git-lfs,

• commit & push everything
• create a branch, something like fix/remove-lfs
• remove hooks git lfs uninstall
• remove lfs stuff from .gitattributes (open file, delete content - don't delete the file!)
• list all lfs files, git lfs ls-files
• run git rm --cached for each file
  • if your list is big, copy the contents into a file.txt
• make sure you remove the number and asterik on each line, you only want the paths to the files

Gitlab exports repositories to tar archive which contains .bundle files.

We have repo.bundle file and we want to restore files from it.

• create bare repo from bundle file

git clone --mirror myrepo.bundle my.git

#ifdef SHELL
g++ -Wall -Werror -g -I../../cclib/rapidjson/include $0 && ./a.out
exit 0
#endif

// Output is:
// {"project":"rapidjson","stars":11}
// {"Name":"XYZ","Rollnumer":2,"array":["hello","world"],"Marks":{"Math":"50","Science":"70","English":"50","Social Science":"70"}}
// {"FromEmail":"sender@gmail.com","FromName":"Sender's name","Subject":"My subject","Recipients":[{"Email":"recipient@gmail.com"}],"Text-part":"this is my text"}
