The problem is that many of the described sex acts are non-consensual and thus abuse. Instead of contending with this, the book romanticizes them as overcoming broader societal power structures by violating the boundaries of individuals. /post/cusk/ Sun, 13 Oct 2024 00:00:00 +0000 /post/cusk/ Rachel Cusk’s Parade has recently thrown my mind into turmoil a few times. Its prose can be treacherous, like a ragged mountain. But when it becomes lucid to me, it stabs. It has been quite some time since I’ve felt the need to make excerpts from a book as not to lose these nuggets. One of them prompted me to write this post. Let me share it with you: You’re white and you’re male and things just fall into your lap, and I’m not saying that’s your fault. /post/nurturing/ Sun, 17 Mar 2024 00:00:00 +0000 /post/nurturing/ For a while I head loose thoughts swriling around about how my outlook on teaching has changed and possibly, I&rsquo;ve grabbed them and pinned them down into prose. /post/cant-write/ Fri, 22 Dec 2023 00:00:00 +0000 /post/cant-write/ On the train, I wrote a quick piece about why I fail to write more, how distraction and perfectionsim play a role. /post/tutor/ Sat, 01 Aug 2020 00:00:00 +0000 /post/tutor/ Im Sommersemester 2020 hatte ich die Chance als Tutoren Studierenden durch eine Mathevorlesung zu helfen. Das habe ich gelernt. /post/beweis-differentialrechnung/ Wed, 29 Jul 2020 00:00:00 +0000 /post/beweis-differentialrechnung/ Diese kleine Aufgabe führt einige Kernkonzepte der Analysis zusammen. Ich fand&#39; sie ganz nett. /post/minesweeper/ Sun, 26 Jul 2020 00:00:00 +0000 /post/minesweeper/ Minesweeper is a fun game the came with earlier Windows versions. In this post I will prove a fun result about a related problem. /post/ti2/ Wed, 22 Jul 2020 00:00:00 +0000 /post/ti2/ Diese Aufgaben sollen beim Lernen für die TI-2-Klausur am HPI vorbereiten. /post/drift/ Sat, 27 Jun 2020 00:00:00 +0000 /post/drift/ Drift-Theorie ist ein mächtiges Werkzeug, um Zufallsprozesse zu analysieren, wenn man in der Lage ist eine Schranke für die erwartete Veränderung in einem Schritt zu finden. /post/ea/ Mon, 01 Jun 2020 00:00:00 +0000 /post/ea/ Evolutionary Algorithms use a simulation of genetic mutation to find a solution to an algorithmic problem. /post/babyrudin-example-76/ Sat, 11 Apr 2020 00:00:00 +0000 /post/babyrudin-example-76/ Rudin mentions that an interesting property can be proven but does not show how. /post/beispiel-beweise/ Sat, 11 Apr 2020 00:00:00 +0000 /post/beispiel-beweise/ Auch schlechte Beweise können lehrreich sein. /post/reduktionen/ Wed, 27 Nov 2019 00:00:00 +0000 /post/reduktionen/ Wie können wir Mengen bezüglich ihrer Schwierigkeit vergleichen? /post/installing-podman/ Tue, 26 Nov 2019 00:00:00 +0000 /post/installing-podman/ Installing podman has a few pitfalls. Here&#39;s what I had to do. /post/postgres-local/ Tue, 23 Jul 2019 00:00:00 +0000 /post/postgres-local/ I recently had to setup a local database for testing purposes. The last time I did that was on Mac OS. On that platform the awesome Postgres.app is available that sets up a dev database in seconds. (Seriously, if you are a developer on Mac you should check that out.) On Linux — and in my case NixOS – the process is more involved unfortunately. You can&#39;t (as far as I know) just put something into your dev environment shell. /post/nice-linux-software/ Sun, 07 Jul 2019 00:00:00 +0000 /post/nice-linux-software/ Ripgrep Imagine grep or pt, but really really fast. Skim With Skim you can really easily find files in the terminal. It easily integrates with other UNIX commands. I use the following to easily open folders: alias c &#34;cd (sk)&#34;. Entr This is also a utility that can be integrated with other commands. It&#39;s a file watcher that just works. I use it with nix-build to get it to file watch. /post/backup/ Sat, 06 Jul 2019 00:00:00 +0000 /post/backup/ A short while ago I had a catastrophic drive failure. While I was able to reuse the drive itself, all my files were lost. I have all my important files in git Repos. That includes my whole system configuration. (The beauty of nix.) This was the saving grace. I could recover my setup quite easily, but not as easily as I had hoped. It took up almost an entire day. /post/ctf/ Thu, 06 Jun 2019 00:00:00 +0000 /post/ctf/ I have built a small web-related Capture The Flag. Try to find all six flags. Go to http://ctf.beb.ninja to start! (Alternatively you can run a docker image locally.) /post/olaf/ Sun, 02 Jun 2019 00:00:00 +0000 /post/olaf/ Ich habe einen Hund. Er ist supersüß. Hier ein Bild: &lt;img src=&#34;/images/dog.jpg&#34; /&gt; Er ist auch ganz lieb und sicher kein Kampfhund. Trotzdem ist es erforderlich, bei der Stadt Potsdam ein polizeiliches Führungszeugnis vorzulegen. Toll ist, dass man das direkt online beim Bundesministerium der Justiz und für Verbraucherschutz beantragen kann. Mit der Online-Funktion des neuen Personalausweises kann man sich bei OLAF anmelden. (Das funktioniert auch mehr oder weniger gut. /post/topfsecret/ Fri, 10 May 2019 00:00:00 +0000 /post/topfsecret/ TopfSecret: So heißt eine gemeinsame Aktion von FragDenStaat und foodwatch. Dort kann man ganz einfach die Hygienekontrollberichte von Restaurants, Gaststätten usw. anfragen. Diese Anfragen werden nach dem Verbraucherinformationsgesetz an die lokale Aufsichtsbehörde gestellt. Hier in Potsdam ist das die Veterinär- und Lebensmittelüberwachung des Fachbereichs Soziales und Gesundheits des Rathauses. Dass diese Informationen in Deutschland nicht öffentlich sind, verwundert mich und viele andere. In den Vereinigten Staaten z. B. müssen Betriebe das Resultat sogar gut sichtbar im Gastraum oder Schaufenster aushängen. /post/email/ Tue, 07 May 2019 00:00:00 +0000 /post/email/ Previously I had been using Thunderbird for all my desktop email. It&#39;s nice. It has good PGP support (via enigmail). Just one thing really irked me: Search sucked. It was aweful. It was slow, it barely ever found what I was searching for without manually adjusting search parameters like ordering. I am a fan of emacs. I use a heavily modified version of Spacemacs and I have tried to setup e-mail for it multiple times and never achieved what I wanted to. /post/auswahlseminar/ Mon, 25 Feb 2019 00:00:00 +0000 /post/auswahlseminar/ Am ersten Februarwochenende durfte ich an einem Auswahlseminar teilnehmen. Es war für Studienanfänger:innen bestimmt, die von ihrer Schule für die Studienstiftung des deutschen Volkes vorgeschlagen worden sind. /about/ Thu, 21 Feb 2019 00:00:00 +0000 /about/ Hi, I am Ben.
