Takes real time stream from Enphase Envoy and publishes to mqtt broker

A Python script that takes a real time stream from Enphase Envoy and publishes to a mqtt broker. This can then be used within Home Assistant or for other applications. The data updates at least once per second with negligible load on the Envoy. Requirements An Enphase Envoy. Note – Tested with Envoy-S-Metered-EU A system running python3 with the paho.mqtt python library The normal way to install paho.mqtt is pip install paho-mqtt If that doesn’t work, try git clone https://github.com/eclipse/paho.mqtt.python […]

Enables increment operators in Python with a bytecode hack

Enable ++x and –x expressions in Python What’s this? By default, Python supports neither pre-increments (like ++x) nor post-increments (like x++). However, the first ones are syntactically correct since Python parses them as two subsequent +x operations, where + is the unary plus operator (same with –x and the unary minus). They both have no effect, since in practice -(-x) == +(+x) == x. This module turns the ++x-like expressions into x += 1 at the bytecode level. Increments and […]

Demonstration that AWS IAM policy evaluation docs are incorrect

The flowchart from the AWS IAM policy evaluation documentation page, as of 2021-09-12, and dating back to at least 2018-12-27, is the following: The flowchart indicates that an Allow in a resource policy causes a final decision of Allow, before permissions boundaries have a chance to cause an implicit Deny. This would mean a resource policy could unilaterally grant access to a principal, circumventing its permissions boundary. However, this is only partially correct. Resource policies cannot unilaterally grant access to […]

Middleware that Prints the number of DB queries to the runserver console

Inspired by this post by David Szotten, this project gives you a middleware that prints DB query counts in Django’s runserver console output. Installation pip install django-querycount Just add querycount.middleware.QueryCountMiddleware to your MIDDLEWARE. Notice that django-querycount is hard coded to work only in DEBUG mode set to true Settings There are two possible settings for this app: The first defines threshold values used to color output, while the second allows you customize requests that will be ignored by the middleware.

Polyp-PVT: Polyp Segmentation with Pyramid Vision Transformers

by Bo Dong, Wenhai Wang, Deng-Ping Fan, Jinpeng Li, Huazhu Fu, & Ling Shao. This repo is the official implementation of “Polyp-PVT: Polyp Segmentation with Pyramid Vision Transformers”. 1. Introduction Polyp-PVT is initially described in arxiv. Most polyp segmentation methods use CNNs as their backbone, leading to two key issues when exchanging information between the encoder and decoder: 1) taking into account the differences in contribution between different-level features; and 2) designing effective mechanism for fusing these features. Different from […]
