From a while back, in response to Brexit people wanting to have a second home in France but refusing to speak French at all, but basically demanding a second UK in France.
[Wayback] Thread by @jpluimers on Thread Reader App – Thread Reader App / [Archive.is] Jeroen Pluimers on Twitter: “Note that I find French a beautiful, but tough to learn language. This has to do both with dyslexia and autism. I still try. Which leads to odd and humorous situations. 1/… “:

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.
Of note for e-mail are
example,invalid,example.com,example.net, andexample.org.
example.edu on the same level as example.com, example.net and example.org; this is not true, despite the domain being registered by the IANA, the IANA is not the registrar of the .edu domain)Reserved by RFC 2606 and explained further in RFC 6761:

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):
input field being marked with type="password", and if not add it.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:
Freshping FREE plan ✓ 50 URL checks ✓ 1-minute interval ✓ FREE Public status pages. Need more? Check out the enterprise plan.
50k API check runs / mo, 5k browser check runs / mo, 5 users, basic features

A few links and notes:
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
Cause
The name resolution parameters were not properly configured during the installation of the ESX host.
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:
osqueryis 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.
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,osqueryiis an invaluable tool when performing incident response, diagnosing a systems operations problem, troubleshooting a performance issue, etc.

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.
