The instructions were tested on a Lenovo X1 Carbon 5th Gen (X1C5) on Arch Linux but should be applicable to other Lenovo models and Linux distributions.
BACKUP YOUR DATA! I created a bootable Ubuntu Image like this:
$ sudo sh -c 'curl --location --silent --fail "http://releases.ubuntu.com/18.04/ubuntu-18.04.1-desktop-amd64.iso" | pv > /dev/<your-usb-drive>'
# note that pv is only there to show progress, it is perfectly fine to redirect curl to the usb drive directly.then I booted from this drive by pressing F12 on reboot and dumped my NVMe disk to an external hard drive like this:
| #### Contents of the preconfiguration file (for stretch) | |
| ### Localization | |
| # Preseeding only locale sets language, country and locale. | |
| d-i debian-installer/locale string en_US.UTF-8 | |
| # The values can also be preseeded individually for greater flexibility. | |
| #d-i debian-installer/language string en | |
| #d-i debian-installer/country string US | |
| #d-i debian-installer/locale string en_US.UTF-8 |

| "2) Extract the downloaded image with ‘sudo’ to allow ‘mknod’ commands to work" | |
| # get a cloud image from here | |
| # https://cloud-images.ubuntu.com/daily/server/xenial/ | |
| # https://cloud-images.ubuntu.com/daily/server/xenial/current/ | |
| # based on https://bazaar.launchpad.net/~maas-images-maintainers/maas-images/maas-ephemerals/view/head:/bin/img2squashfs#L161 | |
| # extract a cloud image rootfs to a directory, sudo is needed for `mknod`s to work | |
| # doesn't have to be .tar.gz - could well unsquashfs an existing squashfs |
This is a guide that I wrote to improve the default security of my website https://fortran.io , which has a certificate from LetsEncrypt. I'm choosing to improve HTTPS security and transparency without consideration for legacy browser support.
WARNING: if you mess up settings, lose your certificates, or decide to no longer maintain HTTPS certs, these steps can and will make your domain inaccessible.
I would recommend these steps only if you have a specific need for information security, privacy, and trust with your users, and/or maintain a separate secure.example.com domain which won't mess up your main site. If you've been thinking about hosting a site on Tor, then this might be a good option, too.
The best resources that I've found for explaining these steps are https://https.cio.gov , https://certificate-transparency.org , and https://twitter.com/konklone

Those are my personal notes on AWS Solution Architect certification preparation. Hope you find them usefull.
To pass AWS certification, you should have:
- Sound knowledge about most of the AWS services ( EC2, VPC, RDS, Cloudfront, S3, Route53 etc,)
- Hands on experience with AWS services.
