  2. Ausringen
  3. Anziehen

Heisses Wasser, damit man beim Anziehen keinen Kälteschock bekommt.

Das nun lauwarme T-Shirt kühlt sehr schnell ab. Fertig ist die eigene Klimaanlage!

Jährlich treffen sich alle Hackerspaces aus der Schweiz zu einem kleinen Kongress – dem Cosin. „Wir treffen uns jetzt schon so lange, und es gibt noch immer keine Videos von den Vorträgen“ habe ich mir vor dem Cosin 2017 gedacht. Nun denn – dann „vergesse“ ich doch mal meine kleine Kamera und ein Stativ im Rucksack und frage am Abendtisch spontan, ob wohl jemand etwas dagegen hätte, wenn ich Vorträge aufzeichne. Natürlich hatte niemand etwas dagegen. So entstanden die ersten fünf Videoaufzeichnungen vom Cosin.

Ein Jahr später, Anfang 2018. „Du hast doch Videos gemacht. Können wir das dieses Jahr wiederholen und noch mehr Videos aufzeichnen? Wie kann man das noch besser machen? Der befreundete Hackerspace vom Bodensee hat zwei Kameras und die sind grad eine kleine Infrastruktur für Vortragsaufzeichnung am Aufbauen.“ „Klingt nach Videomischen und Mini-VOC. Ich schau mal, was es so gibt und überleg mir was.“

Kalashnikov presentiert sein „REX-1“ -- mit Red Dot Visier und allem, was man sich so wünschen kann 😀

Russian weapons manufacturer Kalashnikov demonstrated its REX-1 anti-drone gun at the International Military-Technical Forum ‚Army 2017‘ expo.

Rex-1 is a non-lethal device that works by severing the connection between a quadcopter and its controller, as well as jamming satellite positioning systems, GSM and Wi-Fi signals.

Sehr schön. Die erste positive Waffe! Endlich können wir uns gegen Polizeiüberwachungsdrohnen wehren.

*Blink blink blink* -- „Nein Bub, du kommst jetzt da runter.“
Und das erst noch nondestruktiv. Wunderbar!

Dauerauftrag Mitgliederbeitrag für den Chaos Computer Club Zürich. Oh, ein Freitextfeld! Vier Zeilen Spielplatz, wo ich mich austoben kann!

Angefangen mit SQL-Injections, habe ich es später ergänzt mit <script>-Tags und nicht-druckbaren Unicode-Sonderzeichen. Einfach nur um zu schauen, ob es denen das System verjaggt. Ist schliesslich nur ein Mitteilungsfeld, da darf ich reinschreiben, was ich will. Das geht die Post nichts an, es gilt das Bankgeheimnis.

Also, was ist das Illegalste, was man da noch reinschreiben könnte? Kumpel von mir hatte mal eine Bestellung Holz als „Spaltbares Material“ bezeichnet und dann einen Brief von der Post bekommen. Gut, etwas mit Atombomben, das nehmen wir!

Ein guter Anfang -- sowas hätte ich mir damals gewünscht, zu meiner Schulzeit. Allerdings ist das immer noch viel zu wenig; und dass die Lernprogrammierumgebung Geräusche von sich gibt, wenn man etwas kompiliert oder Knöpfe drückt, ist ein weiteres Beispiel davon, dass Kinder von Erwachsenen nicht wirklich ernst genommen werden. Mir ging die kindische Aufmachung mit Bären und Robotern schon als Kind auf den Sack, und warum muss etwas lustig piepsen und sich animieren, obwohl es sonst keinen Zweck erfüllt? Weil die Erwachsenen meinen, etwas sei nur kindergerecht, wenn es so verniedlicht wird? Ich bitte euch. Eine weitere künstliche Grenze, die nicht sein müsste. Man kann etwas auch in kleinen Schritten lernen, ob als Kind oder Erwachsener. Bei Minecraft jubeln schliesslich auch keine Roboter und Barbies, wenn man zum ersten mal erfolgreich etwas automatisiert hat, und Minecraft spielen die Kinder gern. Zurecht hat jemand am Ende diese Verniedlichung in Frage gestellt, begleitet von zustimmendem Applaus.

Und dann diese Annahme -- „können die Kleinen das?“ UND OB. Was soll diese Frage?!? Aber natürlich können die das! Wenn man ihnen nur die Möglichkeit gibt. Woher kommt diese Annahme, dass Kinder etwas noch nicht können sollen oder sich nicht dafür interessieren würden? Erwachsene und ihre Kinderfilterblasenfantasiewelt. Die Ergebnisse des Bildungsexperiments überraschen mich nicht im geringsten: Kinder können programmieren und löten und sich dafür begeistern.
