Ich nutze das neue (gebrauchte) #T570 aktuell für Tests von $Dingen, die ich mir auf meinen sonstigen Systemen (noch) nicht traue. Schön ist, das es halbwegs aktuelle #Hardware ist.

Aktuell teste ich die Absicherung der Boot-Chain und die Verschlüsselung der Systempartition mit #LUKS + #clevis + #systemd + #TPM2 + #SecureBoot.

Ich habe lange über die Sinnhaftigkeit gezweifelt, aber mittlerweile verstehe ich das Konzept etwas besser. Praxiserfahrung hilft mir da enorm.

Aktuell habe ich die Kombination einer 6-stelligen PIN mit dem TPM2 des #Notebooks, um die Partition zu entschlüsseln. Da erscheint mir momentan ein ausreichender Kompromis zwischen Sicherheit und Nutzbarkeit.

Jetzt schaue ich mal, wie sich das mittelfristig im Betrieb schlägt. Vor allem, ob es zu Fehlern bei Upgrades kommt, die mir potentiell den Zugriff auf das System kaputt machen könnten.

From Milliseconds to 26 Nanoseconds: How a $20 eBay SFP Module Beat My Entire NTP Setup - Austin's Nerdy Things

Welcome to Austin’s Nerdy Things, where we spend years chasing nanoseconds that nobody asked us to chase. Five years ago, I started this blog by building a microsecond-accurate NTP server with a Raspberry Pi and PPS GPS.

Cover (video thumbnail) of the video: it shows a view of the tablet on my desktop, with keyboard on the top and the title (XPPen Artist 16 Pro Gen2 Review) in big, not that I want to poluate your TL, it's just the size necessary for a thumbnail on video platform. 😉

It turns out that the fabric seat cover, and/or the gas suspension creates such a strong electrostatic discharge (ESD) that my screen shuts off for a short time.

The solution? No idea yet, but it seems that insulating the chair with copper foil and connecting it to a socket (ground) might help. 🤦‍♂️

Welcome to 2023 - Your Ikea "MARKUS" chair is not compatible with your screen 👏

(Not my chair, the picture is from the forum post)

So folks, don't forget to check if your Ikea chair is compatible with your screen. I'm not kidding. A thread 🧵.

I've had the problem with my new screen for several weeks now, that every now and then the screen goes black for a few seconds.

Today I had enough and wanted to investigate the problem. So I started changing all the cables, plugging the screen into a different socket, and and and. Nothing helped.

I made a new video about improvements, modifications, and tweaks I made to my tablets: overlay sheet (Photodon), keyboard tray (Cintweak), a real bug issue under the glasses, and a too-grainy overlay surface for the Intuos Pro Large.

Various hardware reviews: Photodon overlays, Cintweak keyboard trays, real bugs, and Intuos Pro.

Improvements, modifications and tweaks at home with my tablets: I put an overlay sheet of Photodon on my XP-Pen 24 Artist Pro, I adapt a keyboard tray made for Cintiq for the XP-Pen 24 Artist Pro and Cintweak helps me, I then test their Universal UNI…

Unterschiede be Lenovo-Notebooks?
Ich versuche gerade heraus zu finden, wo bei #Lenovo die relevanten Unterschiede zwischen diesen Modellen liegen:
*T590
*L590
*T15 Gen. 1

Ergebnis bislang: nur T15 hat scheinbar Touch-Display

Ja, ich weiß, dass es auf der Website die Compare-Funktion gibt.
Mich würde mehr interessieren, was so die groben Zielsetzungen der unterschiedlichen Modelle sind, ich habe da noch kein Muster erkannt. Warum L und T?
