System administration is a special are of IT. It also has a special place in my heart. It is an interesting mixture of all the other disciplines, both common across the whole industry, and at the same time unique for each person, company, and geographical location. When I have something to say or share about system administration, I use this category.
As someone who went through a whole pile of trying and error with Amazon AWS, I strongly recommend reading anything you can on the subject before you start moving your business to the cloud (not even necessarily Amazon, but any vendor), and while you have it running there. Â “The AWS spend of a SaaS side-business” is a good one in that category.
Fedora 26 has been release about a month and a half ago. Â But I didn’t have the time to update my laptop until today. Â There was also nothing particularly exciting for me in this release, so there was no rush.
Here’s what I had to do today to update my laptop from Fedora 25 to Fedora 26:
# Let's get into root to save a few keystrokes sudo su - # Install all updates for Fedora 25 dnf update # Install dnf system upgrade plugin dnf install dnf-plugin-system-upgrade # Download upgrade packages for Fedora 26 dnf system-upgrade download --refresh --releasever=26 # Reboot and install Fedora 26 dnf system-upgrade reboot
If you need more help, have a look at DNF system upgrade wiki page.
The whole process took less an hour, but your mileage may vary. Â For me, the download itself was the slowest part. Â I had to pull down about 2.5 GBytes worth of packages, and given my office connection, it took about 35-40 minutes.
The installation itself took about 10-15 minutes, for which, I think, the solid-state disk (SSD) helped a lot.
One more reboot later, everything was up and running. Â Of all the changes pushed into this version, I think, the upgrade to PHP 7.1 is the one that affects me the most.
Web Hosting Geeks published a very extensive research into domain names and web hosting provider options. Â It includes the analysis of domain name trends by TLD, as well as over 24,000 hosting companies and how they are doing.
Complete with reviews, and detailed stats about each and every company, I think, this is one of the most complete and in-depth data I’ve seen for a long time.
I knew about git interactive staging for a while now, but I’ve never really used it. Â Most days I work on a single feature or bug fix at a time and can commit sequentially, one change after another. Â For an occasional mess, I found git interactive staging user interface too be too cumbersome.
The last couple of days at work were quite chaotic, with me jumping from one thing to another, and I decided to master that feature once and for all. Â Looking for a better tutorial, I came across this blog post, which covers the interactive staging, but also provides a much simpler approach – “git add –patch“.
It’ll take some practice to get it into my finger memory, but I think I’m settled now.
Graphical vi-vim Cheat Sheet and Tutorial is yet another attempt to explain and visualize Vim commands to the editor’s new users.
This is a single page describing the full vi/vim input model, the function of all keys, and all major features. You can see it as a compressed vi/vim manual.
