I have updated CTOP.py so now it detects if is running in a Google GCP instance.
So the list of instances/type of virtualization detected is:
Amazon AWS
Google GCP
OpenStack
VirtualBox
Docker containers
LXC
I’m working in detecting Raspberry Pi, models running CTOP, and in enabling the plugins system so anybody can easily expand the functionality of ctop.py.
v.0.7.8 Commented annotations and type hinting, to make CTOP compatible with Python 3.5.0. Added Available RAM. Added Google GCP detection. Inform if it doesn't have permissions to decode DMI. Print the userId (numeric) and the User (string), like: 1000 carles or 0 root. Logic for swappiness <= 10 Ok, >10 and <= 30 warning, >30 red (alert). Reduced digits for swap to 2, to avoid confusions.
I have updated my book Python 3 Combat Guide, with another full cycle, step by step, to convert an ugly script that escapes to shell to a nice OOP code with Unit Testing, step by step.
I have updated my book ZFS for Ubuntu 20.04 LTS, adding how to create a pool and Datasets for home, sharing NFS for the Media Player.
If you like Star Wars and the Mandalorian, you may laugh has much as I did with this video:
As you see I’m writing more articles about Windows, Mac Os X, and proprietary Software. Some of my colleagues work in companies and use proprietary Software, so I’ll be writing more articles about those ecosystems. I spend more time now with colleagues working on all kind of projects, and with students that have other problems too, so I help them. However my main focus is Open Source, Architecture, Scaling, programming in Python and Java.
I have benchmarked three different CPUs and two Compute optimized Amazon AWS instances with CMIPS 1.0.5 64bit. The two Intel Xeon baremetals equip 2 x Intel Xeon Processor and the third baremetal equips a single Intel Core i7-7800X:
If you’re surprised by the number of cores reported by the Amazon instance m5d.24xlarge, and even more for the baremetal c5n.metal, you’re guessing well that this comes from having Servers with 4 CPUs for Compute Optimized series.
When I can choose I use Linux, but in many companies I work with Windows workstations. I’ve published a list of useful Software I use in all my Windows workstations.
WFH I currently use two external monitors attached to the laptop. I planned to add a new one using a Display Port connected to the Dell USB-C dongle that provides me Ethernet and one additional HDMI as well. I got the cable from Amazon but unfortunately something is not working. In order to make myself comfortable and see some the graphs of the systems worldwide as I have on the office’s displays, I created a small HTML page, that joins several monitor pages in one single web page using frames. This way I only have one page loaded on the browser, maximized, and this monitor is dedicated to those graphs of the stats of the Systems. Something very simple, but very useful. You can extend the number of columns and rows it to have more graphics in the same screen.
If you don’t have the space or the resources for more monitors you can use the ingenious.
I have a cheap HDMI switch that allows me to do PinP (Picture in Picture) with one main source on the monitor, and two using a fraction of their original space. It may allow you to see variants in graphics.
And in you have only a single monitor, you can use a chrome extension that rotates tabs, which is also very useful.
Be careful if you use the reload features with software like Jira or Confluence. If they are slow normally, imagine if you mess it by reloading every 30 seconds… I discourage you to use auto refresh on these kind of Softwares.
This past week I have connected the XBOX One X Controller to the Windows laptop for the first time. Normally I use the Pc only for strategy games, but I wanted to play other games like Lost Planet 3, or Fall Guys in a console mode way. I figured that would be very easy and it was. You turn on the controller, press the connect button like you did to pair with the console, and in Windows indicate pair to a Xbox One controller. That’s it.
I’ve also updated my Python 3 Combat Guide, to add the explanation, step by step, about how to refactor and make resilient, and add Unit Testing to a spaghetti code, and turn it into a modern OOP. Is currently 255 DIN-A4 pages.
This is something I wanted to share with you for a while. One of the most funny things in my career is what I call: Squirrel Strikes Back
I named this as the first incident where a provider told that the reason of a fiber failure was a squirrel chewing the cable.
I popularized this with my friends in Systems Administration and SRE and when they suffer a Squirrel Attack incident, they forward it to me, for great joy.
I’m used to construction or gas, water, electricity, highways repair operations on the cities accidentally cutting fiber cables, thunders or truck accidents on the highway breaking the floor and cutting tubes and issues like that. I’ve been seeing that for around 25 years.
So the first time I saw a provider referring to a squirrel cutting the cables it was pretty hilarious. :)
In my funny mental picture: I could visually imagine a cable thrown in the middle of the forest, over trees, and a squirrel chewing it as it tastes like peanuts. :) or a shark cutting a Google’s or Facebook’s intercontinental cable thrown without any protection. ;)
The sense of humor and the good vibes, are two of the most important things in life.
