macos – Upgrade all the casks installed via Homebrew Cask – Stack Overflow

Posted by jpluimers on 2020/03/23

I missed that this was merged to master a few months ago: [WayBack] macos – Upgrade all the casks installed via Homebrew Cask – Stack Overflow:

December 2017 Update

I thought it would never happen, but there is now finally an official upgrade mechanism for Homebrew Cask (see [WayBack] Issue 3396 for the implementation)! To use it, simply run this command:

brew cask upgrade

However this will not update casks that do not have versioning information (version :latest) or applications that have a built-in upgrade mechanism (auto_updates true). To reinstall these casks (and consequently upgrade them if upgrades are available), run the upgrade command with the --greedy flag like this:

brew cask upgrade --greedy

It means you do not need manual scripts any more. So you can do without this workaround: [WayBack] GitHub – buo/homebrew-cask-upgrade: A command line tool for upgrading every outdated app installed by Homebrew Cask.

More information at [WayBack] homebrew-cask/USAGE.md at master · caskroom/homebrew-cask · GitHub: Updating/Upgrading Casks

PC to TV HDMI image too large for screen – [Solved] – Graphics Cards

Posted by jpluimers on 2020/03/23

Someone Somewhere said:

It’s a setting in the TV. Look for terms like ‘overscan’ , ‘pixel perfect’, ‘1:1’, or similar. Usually under the HDMI settings for that input.

In my case (my mother’s Samsung), the original setting was 16:9 which failed. What works is screen fit. Go figure.

Filezilla – keeping the filestamps on transferred files.

Posted by jpluimers on 2020/03/23

Boy, I wish “Preserve timestamps of transferred files” was in the settings in addition to the menu as I was searching for it there to ensure download timestamps were of the original files:

If I need to analyse power usage on my Android

Posted by jpluimers on 2020/03/20

A while ago, I had a power issue that somehow resolved itself before I could dig deeper into it, so for next time:

Postfix for relaying SMTP, some info about my own configuration

Posted by jpluimers on 2020/03/20

I’ve a bunch of secondary MX servers using postfix (which I like a lot over sendmail). Basically all their configurations are very similar:

  1. To the file /etc/postfix/relay, add a list of domains to relay for, each ending with a space followed by OK as per
    [WayBack] Configure Postfix to relay mail to multiple internal mail servers w/different domains
  2. Run postmap /etc/postfix/relay to update the relay database file.
  3. Ensure that /etc/postfix/main.cf has these settings (note that the FQDN – in the example smtp3.example.org – isn’t always returned by hostname --fqdn, see below):
    1. inet_interfaces = all
    2. myhostname = smtp3.example.org
    3. smtpd_helo_required = yes
    4. smtpd_helo_restrictions = permit_mynetworks, reject_invalid_helo_hostname, reject_non_fqdn_helo_hostname, reject_unknown_helo_hostname
  4. rcpostfix restart && rcpostfix status

Check the functionality with journalctl -u postfix.

FQDN – how to get myhostname

This usually gives a good indication of your external FQDN, but depending on your network circumstances it might not at all be the FQDN of your machine:

dig +noall +answer +short -x `curl -s ipv4.whatismyip.akamai.com` | sed 's/\.$//'

I got there through these StackExchange answers:

Testing with sendEmail

Then test with sendEmail from [WayBack] GitHub – mogaal/sendemail: lightweight, command line SMTP email client, with statements like these

The most recent version is now at [Wayback/Archive.is] GitHub – zehm/sendEmail: SendEmail is a lightweight, command line SMTP email client.

  • sendEmail -o fqdn=sending.example.org -f sender@example.org -t recipient@example.com -u message-subjetc -s smtp3.example.org -m message-text
  • sendEmail -o fqdn=sending.example.org -f sender@example.org -t recipient@example.com -u message-subjetc -s smtp3.example.org -m message-text -v -v -v -v

If you get an error containing 450 4.7.1 … Helo command rejected: Host not found, then reject_unknown_helo_hostname works, but your -o fqdn= parameter contains an invalid hostname.

More sending examples are in the sendEmail documentation.

Chocolatey and TLS since early 2020

Posted by jpluimers on 2020/03/19

I was upgrading a few older systems that had been off-line for quite a while.

When installing Chocolatey, I bumped into this error:

C:\bin>"%SystemRoot%\System32\WindowsPowerShell\v1.0\powershell.exe" -NoProfile -InputFormat None -ExecutionPolicy Bypass -Command "iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))" && SET "PATH=%PATH%;%ALLUSERSPROFILE%\chocolatey\bin"
Exception calling "DownloadString" with "1" argument(s): "The request was aborted: Could not create SSL/TLS secure channel."
At line:1 char:1
+ iex ((New-Object System.Net.WebClient).DownloadString('https://chocol ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : WebException

So I tried [WayBack] chocolatey “The request was aborted: Could not create SSL/TLS secure channel.” – Google Search

Results indicated TLS 1.1 support was removed early February 2020 from Chocolatey because of security reasons, which impacts the installation on older systems:

Note [WayBack] Chocolatey install Error: The request was aborted: Could not create SSL/TLS secure channel – Stack Overflow with a temporary workaround for Microsoft Windows Server 2016:

Looks like the security protocol changed:

Set-ExecutionPolicy Bypass -Scope Process -Force; [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))

Display the relationships between formulas and cells – Excel

Posted by jpluimers on 2020/03/18

The “Formulas” tab has to buttons that help to Display the relationships between formulas and cells – Excel [WayBack]:

  • Precedent cells —   cells that are referred to by a formula in another cell. For example, if cell D10 contains the formula =B5, then cell B5 is a precedent to cell D10.
  • Dependent cells —    these cells contain formulas that refer to other cells. For example, if cell D10 contains the formula =B5, cell D10 is a dependent of cell B5.

To assist you in checking your formulas, you can use the Trace Precedents and Trace Dependentscommands to graphically display and trace the relationships between these cells and formulas with tracer arrows, as shown in this figure.
