Many times users asked me about a feature of saving Zoom in the email preview in Outlook. Instead of paid plugins and macros, I wanted a built-in option.
As it turned out that this wanted a hundred of people from the Globe.
30.11.2018 appeared information that the feature "Zoom and stick" was finally added to Outlook 2016.
But for 2,5 years (2018 - 2021) the feature doesn't yet appeared in my Microsoft Office Pro Plus 2016.
And now I want to figure it out.
To conduct new research, I needed a WiFi card in a virtual machine. I have the WiFi adapter (Intel Dual Band Wireless-AC 8265) in my Intel NUC5i5MYHE, VMware has VMDirectPath I/O pass-through feature, sounds easy. But it was not easy.
After simple configuration of pass-through the WiFi adapter (including embedded Bluetooth device) appeared in Windows but didn't work. Device status was like this:
This device cannot start. (Code 10)
{Operation Failed}
The requested operation was unsuccessful.
At the same time embedded Bluetooth adapter works properly.
I was wondering how the Hot Add and SCA features affect the performance of small VM (2 vCPU in my case).
Enabling the Hot Add feature disables vNUMA feature that starts working when the number of virtual CPUs is greater than 8 and "can improve performance by facilitating guest operating system and application NUMA optimizations".
According to a good article "CPU Hot Add Performance in vSphere 6.7" this may reduce performance by 2 - 8%.
But does it affect VMs with a small number of vCPU? Let's check.
To mitigate “L1 Terminal Fault” vulnerabilities on Intel processors (CVE-2018-3646) VMware released KB55806. They propose two options:
SCAv1 disables Hyper Threading, but SCAv2 does not. But all of them should affect performance, even though VMware says "Retain up to 100% performance for low to moderate loaded systems".
I care about my own information security and I don't want to put up with such flow of ads.
The first and the simplest step of the fight is AdBlock plugin in the browser.
Ths second step is custom hosts file. In this manner you may protect a few PCs, but it is difficult to cover each device in your network. Also, large hosts file can affect performance.
The third step is your own DNS server that will filter all requests from each device. The solution is Pi-hole.
As a platform for the Pi-hole I choosed a small device NanoPi NEO3 with 4 ARM cores (Cortex-A53 up to 1.3GHz) and 1 GB RAM (DDR4) on Ubuntu Core 18.
The problem.
My MacBook Air (13-inch, Mid 2013) with macOS Catalina (10.15.5) in recovery mode runs on OS X Mountain Lion (10.8).
When I try to connect to WiFi instead of ask a single password it ask me login and password (The WiFi network requires WPA2 enterprise credentials). But I don't use WPA-Enterprise.
After fresh installation of Visual Studio Code I decided install Python extension, but faced with an error "Unable to open 'Extension: Python': XHR failed.".
