Hanjo: Universitätsschule sucht Studierende

Die Universitätsschule ist ein Schulversuch, der neue Konzepte des Lernens in Schule erprobt. Die Schule ist eine Ganztagsschule und gelernt wird hauptsächlich in Projekten. Aktuell hat die Schule 200 Schüler*innen von der 1 bis zu 5. Klasse und wir suchen Studierende, die sich vorstellen können dieses Lernen sowohl in Projekten als auch in Werkstätten zu begleiten. Solltet Ihr/ Sie Interesse haben, freuen wir uns über eine Kontaktaufnahme. unischule@mailbox.tu-dresden.de

Carpe Diem

Whilst motoring gently along the River Wey, there is plenty of opportunity for reflection. As the narrowboat travels at a maximum of 4mph, it’s not unusual to step off the boat and walk along the towpath for a mile or so, rejoining the boat at the next lock. These towpath walks allow a break from the tiller and a time to think, figuratively, where we are going.

The exceptional warm weather in mid-September was a welcome surprise after the unsettled August. I have a birthday in mid-August, and over the years I have memories of torrential downpours, thunder and lightning, and...

Thoughts from the Towpath

Part 1 – The Adventure Begins……

There are few opportunities in our busy lives, to take some time off the day job and spend the time relaxing with friends.  Even more infrequently do those days align perfectly with a period of several days of perfect weather in mid-September.

My friends, from California were about mid-way through their European Grand Tour – that would encompass Ireland, UK and France. My role was to choose a uniquely English leisure activity that would keep us all busy for five days in Surrey, before they departed by channel ferry and train to visit friends and relations...

September Update: The PinePhone is real & shipping soon

Picture of a PinePhone prototype running Plasma Mobile 

Let’s start with a quick recap of last month’s events: the Pinebook Pro went into production, software development on the PineTab started, we announced the SOEdge AI module and introduced our initiative for giving back to PinePhone Linux developers during the community meetup in London. This, however, is hardly everything. Let me segue into the core topic of this month’s update, namely the PinePhone. Behind the scenes prototype PinePhone PCBs and chassis have been produced and undergone extensive testing. With the testing now completed, we made the decision to manufacture a small batch...

Самодельный лазер на парах хлорида меди

В одной из статей, посвященных моему лазеру на парах меди, на основе активного элемента УЛ-102 в комментариях был задан вопрос – а что же будет дальше? Дальше оставалось только найти способ сделать самостоятельно активный элемент лазера. И этот способ был найден. Об этом речь пойдет в сегодняшнем посте.

Tools of the KNOB Attack

This week at USENIX three researchers published information about a new attack against classic Bluetooth. Known as KNOB, the attack takes advantage of a weakness in the Bluetooth specification to force target Bluetooth connections to use 8-bit encryption keys instead of larger keys that would be resilient against brute-force attack.

This weakness in classic Bluetooth (not Bluetooth Low Energy) is a big one. I don’t recall seeing such a significant vulnerability in Basic Rate Bluetooth security since pairing was improved with the introduction of Secure Simple Pairing in Core Specification v2.1 in 2007.

One of the things that intrigued me when I heard about the KNOB attack this week was that it...
