Opinion needed: DIY or branded scanner for scanning film negatives and slides?

Posted by jpluimers on 2018/03/16

I’ve a ton of slides, negatives and photos to scan and want to automate the process as much as possible. Think thousands.

Opinions are welcome on both the hardware to use and the process.

It looks like for slides and negatives the opinions vary between building your own rig, fiddling with flatbed lighting or buying a tad more expensive one.

But that was 3 years ago. How’s the state of the art right now?

0x8024400E error with WSUS SP2

Posted by jpluimers on 2018/03/16

From a note a very long time ago: [WayBack0x8024400E error with WSUS SP2


  1. ensure you have at least KB2938066 installed.
  2. while upgrading WSUS, ensure you reboot the server after each update.

Tumbleweed on Raspberry Pi 3 – Bug 1084419 – Glibc update to 2.27 causes segfault during name resolution

Posted by jpluimers on 2018/03/15

Need to watch these:

A few notes:

  • It is inside the glibc name resolution
  • IPv6 is OK, IPv4 fails.
  • ping/nslookup (which do not depend on glibc) are OK
  • there is an intermediate fix requiring direct osc downloads

A simple test case

Failing situation

$ curl --silent --show-error > /dev/null
Segmentation fault (core dumped)

Succeeding situation

$ curl --silent --show-error > /dev/null

Non related, but in hindsight my own stupid fault during a similar update: a post mortem

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 and do port-mortems.

Which is kind of odd, as the SuSEfirewall2 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.

EmbarcaderoMonitoring – monitoring the Embarcadero internet related services

Posted by jpluimers on 2018/03/15

Over time, there are lots of complaints about Embarcadero related internet services (like forums, QC, Appanalytics, docwiki, blogsweb site, maintenance) so to track uptime, I’ve created a set of EmbarcaderoMonitoring pages:

This is preliminary work based on my own lists of Embarcadero endpoints combined with some research like [WayBack] dnsdumpster and [WayBack] IdentIPSpy

Underneath, they run on the infrastructure which has a limit of 50 free monitors.

It means I have to:

  • trim this down for relevancy
  • better document the endpoint
  • find correct endpoint targets for the black (disabled) and red (down) entries as a few of them might need tweaking
  • maybe split off an insecure and secure version (now most subdomains have both http and https monitored)

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 hacked or TLS certificate issues like in 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.

Stop using anemic daily stand-up questions | Software on a String

Posted by jpluimers on 2018/03/15


Reminding everybody of the actual purpose of the daily stand-up and of the goal(s) you have for the sprint may be all that’s 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.
