Since dd on Apple does not support progress parameters via [Wayback] macos dd progress – Google Search:
- [Wayback] Quick: dd with progress indication on macOS
A nice way I found to get progress indication whilst still being able to benefit from the huge speed increase in using /dev/rdiskX is to install a tool called pv, also known as [WayBack] Pipe Viewer.
Example:
sudo dd if=/dev/rdiskX bs=1m | pv -s 64G | sudo dd of=/dev/rdiskY bs=1m
Another way to achieve something similar would be to use brew to install coreutils, which will come with a newer version of dd that supports the status option.
Example:
gdd if=/dev/diskX of=/dev/diskY bs=1m status=progress
- [Wayback] el capitan – How can I track progress of dd – Ask Different
You just need to enter a controlT character from the keyboard while the dd command is executing.
By pressing the controlT character, you are sending the same SIGINFO signal to the dd command that the command pkill -INFO -x dd sends.
dd itself doesn’t provide a progress bar. You may estimate the progress of the dd copy process by adding a pkill -INFO command though.
Example:
dd if=/dev/zero of=/dev/null bs=64m count=1000 & while pkill -INFO -x dd; do sleep 1; done
- [Wayback] dd progress indicator on OSX
signal siginfo is coupled to key-combination CTRL-T. No need to use kill, you can just type CTRL-T in the terminal window where dd is running.

Note
Though there are .example.edu and .example.info, though used in documentation and registered by IANA, have a status is different from the official Reserved Top Level DNS Names:
This is not exactly the same situation as for say ".example.org", where IANA is the registrant *and* registrar.

For quite some time now, Chrome (think years) refuses to prompt for saving passwords whereas Firefox and Safari do prompt and save them, even for site types that it used to save passwords for in the past.
It has been annoying enough for too long now that I tried to do better than the Google searches I used back when I saw this happen first.
Below are some links based on new searches (starting with [Wayback] adding a password in chrome settings – Google Search); hopefully I can try them after I made a list of sites that Chrome does not show the password save prompt for.
Solutions I tried that failed (but maybe useful for others):
Solutions still to try:

Since uptimerobot has slowly moving free features, part of my family uses it to monitor uptime of their personal stuff, and I don’t want to pay for the free monitoring I do on Embarcadero infrastructure (I know that they have been phasing out older useful sites for ages, but even their main sites were down for 2 days about a year ago).
Yes, I know the competitiveness of [Wayback] Website monitoring – Wikipedia, and I’m glad Uptimerobot has been there for a relatively long time, but alas: for personal use…
The list of of the pricing pages of each site, containing a one line summary blurb if it was available:
- [Wayback] Freshping – Pricing
Freshping FREE plan ✓ 50 URL checks ✓ 1-minute interval ✓ FREE Public status pages. Need more? Check out the enterprise plan.
- [Wayback] Pricing | Checkly

A few links and notes:
- [Wayback] Changing the hostname of an ESX or ESXi host (1010821)
Run these commands to change the hostname in ESXi 5.x, ESXi 6.x,ESXi 7.x, using the command line:
- esxcli system hostname set –host=hostname
- esxcli system hostname set –fqdn=fqdn
- [Wayback] ESX Host appears as localhost.localdomain in VMware Infrastructure/vSphere client (2009720)
The name resolution parameters were not properly configured during the installation of the ESX host.
- [Wayback] Domain repoint for embedded vCenter Server fails with error: “domain_consolidator Failed to set machine id” (71020)
This issue is caused by a mismatch between the FQDN that was configured as the PNID during the vCenter Server deployment and the hostname that is currently configured.
I had a mismatch happen because of the second entry: a host configured in a different domain than it was deployed to.
Here are the commands to list and change the hosts name, domain and fqdn:

It’s odd, but facing a potentially lot shorter life expectancy, I need to prepare to become more expendable in personal life.
This means that I need to document or/and automate a lot of duties.
In this case, it is administrative work as custodian for my brother that is based on scripts, Excel sheets and manual steps.
In order to lessen these steps, I wanted to get the formatted value of certain Excel WorkSheet cells so I could concatenate them in other places.
It appears that neither the CONCATENATE function (nor the more recently introduced CONCAT function) nor & concatenation operator just take the unformatted value of the cell and put that in as text.
Note that the TEXTJOIN function is basically a CONCATENATE function with an extra delimiter parameter, so it does not format text.
One format I needed was YYYY-MM-DD, basically the ISO-8601 date format.
The Excel format string for this is yyyy-mm-dd;@, and the corresponding formula to apply it on cell L5 is =TEXT(J5, "yyyy-mm-dd;@")
Based on [Wayback] Get Formatted Value of Cell in Excel – Stack Overflow:
Use the TEXT() function:
TEXT(value, format_text)
So if the value is 23.5 and you pass =TEXT(A1, "$0.00") it will return $23.50
Source: http://office.microsoft.com/en-us/excel-help/text-function-HP010062580.aspx
At a later stage, I will look into the actual format strings.

Almost two years ago, GitHub – facebook/osquery: SQL powered operating system instrumentation, monitoring, and analytics published from the automatic blog queue.
It was in the midst of my rectum cancer treatment, so I was glad the blog queue back then was still about 18 months deep.
This meant I looked into osquery in 2018, which I remember because I needed it on MacOS as I did not want to remember the syntax for MacOS specific commands on getting system information. It also coincides with how much my repository fork was behind: [Wayback: jpluimers/osquery commits/Archive: jpluimers/osquery commits].
Fast forward to now, the breath of systems I’m involved with has widened, so I was glad to see that Kristian Köhntopp mentioned it:
So time to try it again (:
The links he mentioned:
- [Wayback/Archive] Welcome to osquery – osquery
osquery is an operating system instrumentation framework for Windows, OS X (macOS), Linux, and FreeBSD. The tools make low-level operating system analytics and monitoring both performant and intuitive.
- [Wayback/Archive] Welcome to osquery – osquery: High Level Features
The high-performance and low-footprint distributed host monitoring daemon, osqueryd, allows you to schedule queries to be executed across your entire infrastructure. The daemon takes care of aggregating the query results over time and generates logs which indicate state changes in your infrastructure. You can use this to maintain insight into the security, performance, configuration, and state of your entire infrastructure. osqueryd‘s logging can integrate into your internal log aggregation pipeline, regardless of your technology stack, via a robust plugin architecture.
The interactive query console, osqueryi, gives you a SQL interface to try out new queries and explore your operating system. With the power of a complete SQL language and dozens of useful tables built-in, osqueryi is an invaluable tool when performing incident response, diagnosing a systems operations problem, troubleshooting a performance issue, etc.
- [Wayback/Archive] osqueryd (daemon) – osquery
- [Wayback/Archive] osqueryi (shell) – osquery
- [Wayback/Archive] Aggregating Logs – osquery
- [Wayback/Archive] AWS Logging – osquery

Since ESXi boots from RAM, most files in /etc are not persisted after modification.
The files that are persisted, are only persisted once every hour by auto-backup.sh, so better run auto-backup.sh by hand if you want to reboot after changing them.
The auto-backup.sh script is ran every hour at 1 minute past the hour as per below crontab.
Default ESXi crontab in /var/spool/cron/crontabs/root:
#min hour day mon dow command
1 1 * * * /sbin/tmpwatch.py
1 * * * * /sbin/auto-backup.sh
0 * * * * /usr/lib/vmware/vmksummary/log-heartbeat.py
*/5 * * * * /bin/hostd-probe.sh ++group=host/vim/vmvisor/hostd-probe/stats/sh
00 1 * * * localcli storage core device purge
Schedules deciphered via [Wayback] Crontab.guru – The cron schedule expression editor:
- [Wayback] Every day at
01:01: “This module removes stale temporary files”
1 1 * * * /sbin/tmpwatch.py
- [Wayback] Every hour at
*:01: saves backup to /bootbank/state.tgz.
1 * * * * /sbin/auto-backup.sh
- [Wayback] Every hour at
*:00 logs heartbeat messages to /var/log/vmksummary.log like 2021-02-23T19:00:02Z heartbeat: up 577d2h37m16s, 9 VMs; [[2802426 vmx 4194304kB] [6176344 vmx 4194304kB] [68997 vmx 8388608kB]] [[2802426 vmx 0%max] [6176344 vmx 0%max] [68997 vmx 0%max]]
0 * * * * /usr/lib/vmware/vmksummary/log-heartbeat.py
- [Wayback] Every
5th minute logs to /var/log/hostd-probe.log.
*/5 * * * * /bin/hostd-probe.sh ++group=host/vim/vmvisor/hostd-probe/stats/sh
- [Wayback] Every day at
01:00: Removes storage devices which have not been seen in some time interval.
00 1 * * * localcli storage core device purge
Note that localcli commands are the same as esxcli; for esxcli, a running hostd is required; localcli can run without hostd. See:
