Reality update: The aliens are coming. And they’ve caught us with our pants down | James Felton | Opinion | The Guardian … :
“Couldn’t they have shown up during the 2012 Olympics or when Britpop was at its height? Better yet, when Shrek 2 was first released. Apparently not. They want a chinwag with humanity right when we’ve collectively decided to dip our testicles in the Müller Light.“

“Noesis now includes a Roomba script. It will track your Roomba, store tracking data, allow you to visualize that data in a variety of ways, and, of course, turn that data into a randomized DOOM map.“
Reality update: Keylength – Compare all Methods … :
“This web site implements mathematical formulas and summarizes reports from well-known organizations allowing you to quickly evaluate the minimum security requirements for your system. You can also easily compare all these techniques and find the appropriate key length for your desired level of protection. The lengths provided here are designed to resist mathematic attacks; they do not take algorithmic attacks, hardware flaws, etc. into account.“
Very recently I had to convert a PDF (i.e. concatenate three PDFs into one file) and I was blocked for security reasons.
convert *pdf complete.pdf usually adds the files it finds in alphanumerical order to complete.pdf.
But not this time:
“convert: attempt to perform an operation not allowed by the security policy `PDF’ @ error/constitute.c/IsCoderAuthorized/408.”
Googling helped, as it often does, and I found this hint at [Imagemagick security policy ‘PDF’ blocking conversion – Stack Overflow] … :
“Well, I added
<policy domain=”coder” rights=”read | write” pattern=”PDF” />
I added just before in /etc/ImageMagick-7/policy.xml and that makes it work again, but not sure about the security implications of that.”
A comment says that was a Ghostscript vulnerability, but new gs-versions are fine. Let’s hope that’s true…:-)
Update:
Since the convert process resulted in bad quality (after I applied the changes above), I had to do some more homework and play with the values of this convert command:
convert -density 200 -trim [Input_PDF_Files]* -quality 50 output.pdf
In my setup, that ends up with decent quality but 2.5 MByte per page.

“Digitaler Stress in Deutschland – Eine Befragung von Erwerbstätigen zu Belastung und Beanspruchung durch Arbeit mit digitalen Technologien.”
Digitaler Stress: “Stresserleben, welches aus dem Unvermögen eines Individuums resultiert, mit neuer Technologie in einer gesunden Art umzugehen (Brod 1982).”
“Kernergebnis 6:
Frauen arbeiten an digitalisierteren Arbeitsplätzen, sehen sich als kompetenter an und haben ein höheres Level an digitalem Stress als Männer. Frauen nutzen im Durchschnitt 14 unterschiedliche Technologien am Arbeitsplatz, während Männer nur von durchschnittlich 12 digitalen Technologien am Arbeitsplatz umgeben sind.”
“Kernergebnis 8:
Die mit Verunsicherung im Umgang mit digitalen Technologien wird als größter Stressor wahrgenommen, aber auch Unzuverlässigkeit, Überflutung, Verunsicherung, Komplexität, Omni- und Dauerpräsenz. Mehr als ein Drittel der befragten Arbeit nehmer (37,5 %) empfinden ein hohes Maß an Unsicherheit. Demgegenüber empfinden nur 12,7 % ein hohes Maß an Omni- und Dauerpräsenz der Technologien, die somit unter allen sechs Faktoren von digitalem Stress am schwächsten eingeschätzt wird.”
Stichworte:
25% häufiger Kopfschmerzen hat, wer hohen digitalen Stress hat (im Vergleich zu Arbeitnehmern mit normalem Stress)
Digitaler Stress geht mit starkem Konflikt bezüglich der Work-Life-Balance einher (i.e. er wirkt sich auch stark auf das Privatleben aus)
Über 64jährige haben am wenigsten Digitalen Stress, am meisten haben die 35-44 jährigen und die darauf folgenden Jahrgänge.
22% ist der Anteil der Varianz in emotionaler Erschöpfung, der durch digitalen Stress erklärt werden kann.

“This tutorial is mainly for people who have primarily used GUI text editors and coding environments and are not used to a primarily text-based program, running commands in the editor itself, and/or using large amounts of keyboard shortcuts. For reference, here is the list of shortcuts I’ll be introducing in this tutorial:“
“Based on Dahlberg’s theory of concept, and anchored in the pragmatism of Hjørland—in which the concepts are socially negotiated meanings—the evolution of the concept of semantic web (SW) was analyzed in the English version of Wikipedia. An exploratory, descriptive, and qualitative study was designed and we identified 26 different definitions (between 12 July 2001 and 31 December 2017), of which eight are of particular relevance for their duration, with the latter being the two recorded at the end of the analyzed period.“
