Last year, ZeroMQ – of late Pieter Hintjens ancestry – got a decent support library for Delphi https://github.com/grijjy/DelphiZeroMQ.
While writing, there is a reasonable chance I need to do message queue work and ZeroMQ is excellent. I’ve done MQ already in other environments with various projects involving Wintel/iSeries, WebSphere MQ (now IBM MQ, formerly MQSeries), Oracle AQ and Microsofts MSMQ stacks so I’m anxious to see if and how this works out.

Same difference; two tools.
Plastic SCM compare: lots of clutter
Beyond Compare: just the things that are different.

If you ever want to fly a drone without a license in The Netherlands, be prepared that the flying zones are very limited, especially in : [Archive.is] Drone no-fly zones | ministerie van Infrastructuur en Milieu
The text isn’t very clear, even to Dutch people, so there is some discussion and explanation in these links:
More temporary airspace restrictions are here:

A while ago, named would not start any more after I rebooted my Tumbleweed systems.
I had this behaviour on multiple systems, each installed quite a while ago and kept up-to-date with zypper dist-upgrade so it looked like a systematic issue.
Below are steps in researching the problem together with the helpful people on the IRC channel opensuse-factory.
Background reading for some of the commands: [WayBack] How To Use Systemctl to Manage Systemd Services and Units | DigitalOcean.
Both systemctl status named.service and systemctl status named would show the same output:
# systemctl status named
● named.service - LSB: Domain Name System (DNS) server, named
Loaded: loaded (/etc/init.d/named; generated; vendor preset: disabled)
Active: inactive (dead)
Docs: man:systemd-sysv-generator(8)
Getting the log from events around a reboot would show a successful shutdown, but no start:
# journalctl --unit named --catalog --pager-endApr 28 13:19:27 laurel systemd[1]: Stopping LSB: Domain Name System (DNS) server, named... -- Subject: Unit named.service has begun shutting down -- Defined-By: systemd -- Support: http://lists.freedesktop.org/mailman/listinfo/systemd-devel -- -- Unit named.service has begun shutting down.

Similar results in these files:
/var/lib/named/log/general.log
28-Apr-2017 13:19:32.465 general: shutting down: flushing changes
28-Apr-2017 13:19:32.468 general: stopping command channel on 127.0.0.1#953

28-Apr-2017 13:19:32.489 network: no longer listening on 127.0.0.1#53
With systemctl, I got this:
# systemctl is-enabled named named.service is not a native service, redirecting to systemd-sysv-install. Executing: /usr/lib/systemd/systemd-sysv-install is-enabled named enabled # systemctl is-active named inactive # systemctl is-failed named inactive
After this, I was out of systemd and sysv knowledge, so I asked for help on the #openSUSE-factory IRC channel, where ismail was of great help.

It seems there are a few, but only loading the binary is the sure method to know what the process will be using: [WayBack] How to check if a binary is 32 or 64 bit on Windows? – Super User and [WayBack] How do I determine if a .NET application is 32 or 64 bit? – Stack Overflow.
Details in the answers of these questions, here are a few highlights:
dumpbin.exe with the /headers option.sigcheck.exe from SysInternals.file utility (e.g. from cygwin, which comes with msysgit) will distinguish between 32- and 64-bit executables.7z.exe on the PE file (Exe or DLL) in question which gives you a CPU line.File detail is a way to find out if a binary is 32 bit or 64 bit.CORFLAGS utility can be used to determine how a .NET application will run.–jeroen

If you are still on version 8, then note this version will be deprecated at 20180901, so it is time to upgrade to [Archive.is] Microsoft Remote Desktop 10 on the Mac App Store
[Archive.is] Microsoft Remote Desktop 8 on the Mac App Store is now at version 8.0.44, which changed one thing:
This update adds a dismissible banner to the app UI to message the fact that the client will be deprecated soon. You can start using the new version of Remote Desktop today by downloading Microsoft Remote Desktop 10 from the App Store.
It is easy to import your RDP desktops from version 8 into version 18: in the menu, select Connections, then Import from Microsoft Remote Desktop 8, then enter your credentials so the saved logon passwords can be imported from the [WayBack] KeyChain.
A few things to note:
