Heads up: Google to drop support for all Chrome on 32-bit Linux distributions
Chromium engineer Dirk Pranke says Chrome is about to drop support for all 32-bit Linux distros soon. The open source version of Chrome (Chromium) is not affected. I use Google Chrome on the 32bit netbook for Netflix, and I need to either switch to Firefox or upgrade the netbook.

How to setup a intermediate compatible SSL website with LetsEncrypt certificate

How to setup a intermediate compatible SSL website with LetsEncrypt certificate
Many people have decided to implement Let’s Encrypt into their production sites. I find this still a very bad idea to be done without being very (but really very) careful. Let’s Encrypt brings you freedom but also limits you in using the certificate with SHA-256 RSA Encryption. Support for SHA-2 has improved over the last few years. Most browsers, platforms, mail clients and mobile devices already support SHA-2. However, some older operating systems such as Windows XP pre-SP3 do not support SHA-2 encryption. Many organizations will be able to convert to SHA-2 without running into user experience issues, and many may want to encourage users running older, less secure systems to upgrade. In this tutorial, we are going to deal with this incompatibility in a simple, but still nasty way.

Rollback an apt-get upgrade if something goes wrong on Debian / Ubuntu Linux

Rollback an apt-get upgrade if something goes wrong on Debian / Ubuntu Linux
Rolling back to the previous version may solve the problem or free the disk space. Both CentOS/RHEL support rollback feature, but I learned hard way both Debian and Ubuntu does not support rollback feature yet.
