My recently purchased Asus Vivobook 14 Flip (TP3407SA) does not flip into tablet (aka "slate") mode when flipping the lid over. Here is a workaround for Gnome under Debian Trixie. First of all, flipping is recognized under Windows. So it is not a hardware problem. However, searching online was futile: Other people reporting they were unable to get it to work as well Onlline resources suggesting to use libinput or acpi_listen or monitor-sensor or the accelerometer to detect the change and then...| Netfuture: The future is networked
I recently purchased an Asus Vivobook 14 Flip (Model TP3407SA) for use under Linux. One of the obstacles I ran into: Playing sounds resulted in no audio, the device remained mute. However, it had worked under Windows. Time to investigate. This thread for Linux Mint turned out to be very helpful, even though I'm running Debian Trixie. It appears that current Linux kernels do not activate the Texas Instruments audio amplifier (TI chip TIAS2781). However, this can be fixed with a short script by...| Netfuture: The future is networked
I recently wrote a (German) article including this graphic (in German). Here is an English version of it. Have fun! Here it is! The Rupp graph, enhanced with additional trend lies and the «frequency wall» (inspired by The Economist).

There is a German version of the same Graph, with quite a bit of explanatory text. References Marcel Waldvogel: Was Prozessoren und die Fre...| Netfuture: The future is networked
This is the time to catch up on what you missed during the year. For some, it is meeting the family. For others, doing snowsports. For even others, it is cuddling up and reading. This is an article for the latter. I looked at my access logs and started collecting a best-of list, sorted by number of page views. I hope some of them pique your interest. Enjoy! There is also a 🇩🇪German post summarizing the top-ten of my German articles. It is vastly different. Have a look here. 10. «Right ...| Netfuture: The future is networked
The default WordPress «Archive» block becomes very long and narrow, when months accumulate. Here is an easy way to make it more compact. The problem One of my blogs looked like that after a few years of action (wrapped for better visualization; in the original, it is one huge vertical strip): The goal It would be much nicer if it looked like in the heading: One line per year Within each line, the sequence of the months (only those with active posts) Much nicer, isn't it?

«SMTP Smuggling» is a vulnerability that allows to circumvent some mail checks at the receiver and therefore will allow additional spam and/or phishing messages through. Here is the list of what we currently know. Interested in the full story? I have written a German 🇩🇪 article on SMTP Smuggling and SEC Consult's selective (and untimely) disclosure. The SEC Consult article contains information about the software they tested. However, the information is largely unstructured. Here is a...| Netfuture: The future is networked
There was a DEFCON Voting Village panel «If I can shop online, why can't I vote online?» which I found extremely important to read or listen to. Not just for me, in fact, for anyone talking about electronic voting. Here is a transcript for those who prefer reading (or searching for keywords). Of course, a link to the original video may not be missing, for those who prefer to watch or listen. https://www.youtube.com/live/WJjBEhPjLRE Editorial remarks The transcript has received minor editori...| Netfuture: The future is networked

AI art is on the rise, both in terms of quality and quantity. It (unfortunately) lies in human nature to market some of that as genuine art. Here are some signs that can help identifying AI art.
