My Dell Precision M4700 is going to complete 6 years of faultless service, still my main workstation.
It arrived with 3rd gen core i7, 8gb RAM and 750gb 7200rpm hard drive with Windows 7. It gradually transformed into 32gb RAM, 3tb of ssd and Ubuntu 18.04. This dude still runs for days without a problem.
Genuine respect!!
p.s.: If I have to change my next machine, it would be "Dell Precision 7730".

Can someone help in making Google Chrome padlock green or grey (not red)?

This is my understanding of "Machine Learning" in general
There are two sets of data:
1. In first data set, all the properties are known
2. In the second set, some properties are not known.
The goal of the machine learning is to find the value of the unknown properties of the second data set.
We do this by finding (or training) a suitable machine learning model (mathematical, logical or any combination of), that in the first data set, computes the value of the properties, which are unknown in second data set, with minimum error since we already know the real value of those properties.
Now, use this model to predict the unknown properties from the second data set.

Informative article on why Golang is relevant is today's computing ecosystem. I too find many server side programming being done in Golang nowadays. I liked its c like features and simplicity over complexity.

Is there any open / close source application that allows creating browser-based tutorials where the left side would have instructions and the right side section would have terminal to execute the code from the tutorial.
There would be a back-end server to execute the command from terminal and send back the result.
Here is the representative screen-shot:

For Windows driver update, found a great (open source) tool to update or install missing drivers.
https://sdi-tool.org/
My dell laptop (Windows 10) screen used to go blank or some bubble used to appear may times a day. Used Dell driver update tool, no update, says all driver up to date.
Then used Snappy Driver Installer tool, which detected my laptop details correctly.
Then it showed that my display driver was almost a year old and there were couple of updates, latest being just last month. In addition to that, there were 30+ updates on disk drivers, networking, sensors, bluetooth, audio etc.
First updated my display driver, upon success, slowly updated the rest of it. Now, the system worked entire day without any issue. Also, my laptop fan used to run full speed seems to have slowed down.
Also, my external monitor clarity has improved.
ps: worked for me, but be careful. Check it thoroughly before updating, update only those drivers which are giving trouble and there are no updated drivers available from windows or manufacturers.

Just came across this in-browser presentation tool, sozi (free). See it in action
http://sozi.baierouge.fr/presentati...
Just prepare a giant svg file (free inkspace) and create slides like camera panning focusing on each part of the svg file.

Are you using socat?
Any interesting use case you would like to share?
I am using it to create fake / proxy docker containers for network testing.

Do I see standard li-ion batteries? Can it be replaced by ourselves?
If yes, fantastic, wish more manufacturers support this, especially for workstation / development laptops.

Windows 10 - Ghost bubbles
Suddenly the ghost bubbles started appearing, with feverish flickering of cursor, not able to click anything, had to do hard restart and the bubbles disappeared. Happened a couple of times, infrequent.
I thought my PC is virus infected. Upon search, many users reported the same. Looks like some windows update messed up the graphic drivers :(
