A few notes:

Segmentation fault (core dumped)

I thought I had forgot about the SuSEfirewall2 changes (On my research list: migrate from OpenSuSE SuSEfirewall2 to firewalld) so assumed that was the reason I broke one of my secondaries (which runs on a Raspberry Pi 2):
Mistakes like these are the reason to have secondaries in the first place https://infrastatus.wiert.me and do port-mortems.
Which is kind of odd, as the SuSEfirewall2Β didn’t throw any warnings like at this similar one:
This one still works because it is on the firewall in front of the Raspberry Pi 2:
(Screenshots of the above URLs are below).
In fact it was another mistake: I had forgotten to make the DHCP lease static, which resulted in a wrong IP address to be assigned upon reboot, instantly making the firewall rules invalid:
I could have fixed this remotely when I had thought about this.

Over time, there are lots of complaints about Embarcadero related internet services (like forums, QC, Appanalytics, docwiki, blogs,Β web site, maintenance,Β …) so to track uptime, I’ve created a set ofΒ EmbarcaderoMonitoringΒ pages:
This is preliminary work based on my own lists of Embarcadero endpoints combined with some research like [WayBack] dnsdumpster embarcadero.com.pngΒ and [WayBack] IdentIPSpy
Underneath, they run on the uptimerobot.com infrastructure which has a limit of 50 free monitors.
It means I have to:
Any ideas on improving this are welcome: please post a comment here on on the resulting G+ thread.
Note it likely won’t show cases like when the website was hackedΒ or TLS certificate issues like inΒ SSLLabs security reports for some embarcadero subdomains. I need to think about a means for those, as it will certainly help monitoring my own infrastructure in a similar way.

TL;DR:
Reminding everybody of the actual purpose of the daily stand-up and of the goal(s) you have for the sprint may be all thatβs needed to give the shortened versions some much needed context and focus.
Always read the Scrum guide, as it states the purpose of this meeting:
The Daily Scrum is a 15-minute time-boxed event for the Development Team to synchronize activities and create a plan for the next 24 hours.

A very interesting discussion on what the mixing of interfaces and classes can get you into: [WayBack] I’ve got an interface with generics which accepts classes:IMyGeneric = interface…..end;What I want to do is to allow this interface toβ¦ – John Kouraklis – Google+
TL;DR: do not mix interfaces and classes.
As often, AsbjΓΈrn Heid chimes in showing some insight on clever mixing of the two with sample code accepting an unconstrained type. Don’t do that unless you really know what’s going on behind the scenes.

Interesting read of about 20 minutes on the time between the request of an URL and the actual visible rendering clues.
Do libraries and frameworks prioritize components on boot? If so, how, and if not what can we do? And, in exploring that question, I discovered that Server-Side Rendering isn’t a silver bullet!

The state about a year ago was that progressive rendering had the best results as seen on the right.
I wonder if that has changed by now.
