Wolfgang Rupprecht on Dennis H. Klat, Carlos Hawking and Deeklatt – Google+

Posted by jpluimers on 2018/03/18

Wow: [WayBackWolfgang Rupprecht – Google+:

Dennis H. Klatt 1938 – 1988

I knew him at MIT. He was my undergraduate thesis advisor and was a kind and gentle person. When I knew him around 1980 he was about to build the prototype for the first Klatt Talker as it was called then. He had speech samples generated by running his mathematical model of the vocal tract on a large mainframe, but no way to generate speech in real time. I remember being quite happy years later when I heard he had convinced DEC to produce it. The local Boston radio stations would sometimes use it on air when they were goofing around. The initial voice (and the only voice early on) had a bug that made it sound like a Mexican accent to most people. It wasn’t intentional and was a bit of a surprise that a vocal tract modeled from first principles would sound that way. Going with that observation and figuring it was best to advertise bugs as features, the voice was often called “Carlos”. I didn’t realize that Hawking’s voice was also based on the Klatt models (and Klatt’s own voice at that!)

Poking around Google to see what else Google had on him dredged up one more interesting tidbit. There was a character in a TV cartoon called Deeklatt that used his voice. I wonder how many people realize that Deeklatt was a play on D. Klatt. Dennis, we should all be so lucky as to leave a legacy like yours.

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.
