• How To Setup Python3 in Ubuntu Docker Image for AI Deep Learning


    The issue is that Docker images are stripped down, so many tools and even python3 is missing, so you'll have to build or update the actual image yourself. I assume you have started an image with something like this and that you have the Nvidia Toolkit installed (assuming you are using GPUs). If you're not using nvidia just remove --runtime=nvidia --gpus all. docker run -it --runtime=nvidia --gpus all ubuntu bash These works for most images li........
  • How to upgrade to the latest Python version on Linux Ubuntu Debian Mint 3.11


    A lot of developers want to go to 3.11 because of the speed improvements, but most distros never have the latest Python version. Using the deadsnakes third party repo is the easiest way aside from compiling it yourself (which is safer and recommended): Step 1 - Add the repo apt-add-repository ppa:deadsnakes/ppa If you get an error about requests then install it:........

  • How To Enable Nested KVM so guests can virtualize with hardware extensions


    How to check if nested KVM is enabled by doing a cat on nested inside sys Nested KVM is mainly important for testing for example if you wanted to install VMWare or Proxmox Nodes in a virtual environment for testing. Without nesting, the performance will be extremely slow, since the VMs within the nodes will not be using Virtualization extensions. I've used wildcard on kvm_ because it could be kvm_intel or kvm_amd depending on whether y........
  • VirtualBox Nested Virtual Machine Containers with KVM Not Working no SVM or VMX module in the guest


    I can't get vmx cpu extensions to show up in Virtualbox guests despite enabling nested paging and enable vmx in virtualbox guest but this doesn't help that you check VT-X or the AMD Virtualization SVM it enables it for the guest to use BUT does not pass it through. This means if you check cat /proc/cpuinfo in the guest you will see the CPUdoesn't support virtualization. It looks like VirtualBox still hasn't implemented this! But there is good news I&n........
  • Linux SAMBA does not work with symlinks


    At first I thought it's just not possible but there is actually an option that can be enabled to make symlinks work with Samba. Then I put this under the [global] section Note: It's "wide links" and not "wide symlinks" (some other sites have incorrect info which was a frustrating waste of time :)) Add this to your smb.conf follow symlinks = yes wide links = yes unix ex........
  • Linux Mint 17 How to Enable File Sharing Option in File Manager


    I still cannot understand how this would not be enabled by default and I struggled to find the reason why with manually installing samba etc.. wondering why the option for sharing was not in the menu. On Linux Mint "MATE" the package is called "caja-share" and on Cinnamon it is called "nemo-share" so edit the below command as necessary: *Also note that the "samba" package is necessary as it is not inst........

  • Linux how to use find recursively to find certain types of files/extensions


    Normally if you're in a certain directory you could do: find *.txt and it will work as expected, but it won't work recursively through child directories, here's the correct way to do it: find . -type f -name *.txt The "-type f" is optional because that means only files, but we could have specified d for directory etc... The above command will work recursively as you'd expect. In that way I find "find" to be un........

    This is a great way to use your ftp server space, for example on your web hosting account (althoughI believe many hosts don't allow storage like this), but if you have a VPS/Dedicated Server etc.., this would be perfect. Imagine how easy it is to work with an ftp account that you can just mount as a normal partition or directory in Linux, it would be great for backups etc..

Both are excellent tools but for veteran command line users working remotely, using the keyboard is a great and possibly automated way to save yourself pain and hassle.
