Immer wenn ich lese "Kein Backup, kein Mitleid." muss ich mit dem Kopf schütteln. Hier ist nicht nur das "ob" (also warum man Backups machen muss) etwas das IMMER WIEDER erklärt werden muss, Auch das "wie", gerade das "wie", omg ist das "wie" wichtig!
aber abgesehen davon, nur weil man Jahrzehnte in einem Bereich tätig ist, geht ein Thema nicht weg, denn es haben mit der Zeit eben nicht alle verstanden. Muss mich da auch an eigene Nase…

"I want you to imagine someone for me. Her name is Jessica and she is 17 years old...." For years, "A Story About Jessica" (a computer security parable @SwiftOnSecurity@infosec.exchange wrote, published on their Tumblr in 2014) was pretty hard to find. Per the CC BY license, I've now republished it so it's easier to discover and reference. http://harihareswara.net/posts/2024/a-story-about-jessica-by-swiftonsecurity/ My comments in the post include pointers to relevant work by Mark Pilgrim,…

Long-Term Astrometric Monitoring of the Galactic Center Magnetar PSR J1745--2900
We present new astrometric observations of the Galactic Center magnetar, PSR J1745-2900, with the Very Long Baseline Array (VLBA). Combined with previously published measurements in 10 epochs that spanned 477 days, the complete data set consists of 25 epochs and 41 independent measurements that span 1984 days. These data constrain the proper motion to an accuracy of $\lesssim 2\%$ and set an upper limit on the absolute value of the magnetar's acceleration of $\lesssim (0.4, 0.2)\, {\rm mas\,y^{…
