PyDev of the Week: Reimar Bauer

This week we welcome Reimar Bauer (@ReimarBauer) as our PyDev of the Week! Reimar is a core developer of the popular Python wiki package, MoinMoin. He has spoken at PyCON DE, FOSDEM and EuroPython about Python. Let’s take a few minutes to get to know him better! Can you tell us a little about yourself (hobbies, education, etc): I am a programmer from Jülich, Germany. That‘s a small town between Aachen and Cologne. I work at the Forschungszentrum Jülich GmbH. Employees research in the fields of energy and the environment, information and brain research with the aim of providing society with options for action facilitating sustainable development. My work is related to atmospheric science. copyright: Forschungszentrum Jülich GmbH I wrote a few books in the past years about data structures and about IDL, one of my first science related programming languages, developed by Ray Sterner in Boulder, Colorado. In 2012 I was elected to the board of the German Python Software Verband. I helped to organize several Python Events in Germany, several PyConDE and the famous EuroPython in Berlin. I stepped down from this position and I left in 2017 because I needed and wanted to spend more time with my family. I have been a fellow of the Python Software Foundation since 2013. I used to play trombone in a Big Band, but had to take a break because I just couldn’t find the time this hobby needs. I enjoy sightseeing, hiking, sociocracy3.0, meeting a lot of different people. And sometimes I play an augmented reality game named ingress. In 2019 the 10th PythonCamp Cologne Germany, a classic barcamp, will be the next community project Reimar Bauer is involved in.

Оптимизация энергопотребления STM32: практическое руководство

Привет, Хабр! В сети довольно много статей про работу микроконтроллеров STM32 в энергоэффективных устройствах — как правило, это устройства на батарейном питании — однако среди них прискорбно мало разбирающих эту тему за пределами перечисления энергосберегающих режимов и команд SPL/HAL, их включающих (впрочем, та же претензия относится к подавляющему большинству статей про работу с STM32). Тем временем, в связи с бурным развитием умных домов и всевозможного IoT тема становится всё более актуальной — в таких системах многие компоненты имеют батарейное питание, и при этом от них ожидаются годы непрерывной работы. Восполнять данный пробел мы будем на примере STM32L1 — контроллера весьма популярного, достаточно экономичного и при этом имеющего некоторые специфические именно для этой серии проблемы. Практически всё сказанное будет также относиться к STM32L0 и STM32L4, ну и в части общих проблем и подходов — к другим контроллерам на ядрах Cortex-M. Практический результат должен выглядеть примерно так, как на фотографии выше (и да, о применимости мультиметров и других средств измерения к подобным задачам тоже поговорим).

After that I went on studying for a MS in the same field at The University of Arizona, AZ, USA. Then I continued my studies of water resources and was awarded a Ph.D. from the University of Cottbus, Germany. I worked in this field in consulting and research for 11 years at a research institute and four years at a consulting office. In my limited spare time I do some calisthenics, i.e. bodyweight training to keep fit. Pull-ups are fun. 🙂 Continue reading PyDev of the Week: Mike Müller →

Как создать чат-бота для ВКонтакте, используя Python, Django и webhook

Зачем ещё одна статья про создание чат-бота? Возможно я плохо искал, но я не смог найти подробного руководства по созданию бота на python с применением фреймворка Django и подхода webhook, работающего на хостинге от российской компании. В большинстве материалов говориться о применении фреймворка Flask и использования бесплатных хостингов Heroku и PythonAnywhere. Опыт сообщества Хабр меня выручает, поэтому я решил в знак благодарности потратить время на написание данной статьи. Опишу полученный практический опыт, чтобы дать возможность всем кто в этом заинтересован сэкономить время и лучше понять как сделать бота на Python с применением фреймворка Django на своём хостинге, используя подход webhook.
