Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

SmartConfig / ESPTouch Not Working - Any Alternatives?
I was using the ESP8266 RTOS SDK (https://github.com/espressif/ESP8266_RTOS_SDK) and using the smartconfig example (https://github.com/espressif/ESP8266_RTOS_SDK/tree/master/examples/wifi/smart_config) with my iOS app. On the mobile side, I was using the EspressifTouchSDK 1.1.0 (https://github.com/EspressifApp/EsptouchForIOS). Basic need was to transfer WiFi SSID - Password to the Esp from the mobile and smartconfig achieved this fast & easy without hassle.

A Database Without Dynamic Memory Allocation
Imagine my disappointment after working on a statically allocated HTTP server stack to discover that even `esp_log.h` does several malloc() calls [1] per log output line... thankfully that was only on the ESP8266_RTOS_SDK, and esp-idf isn't quite as bad.

Is there an example in the RTOS SDK that lets you enter the wifi name and pass from another device? (instead of hardcoding?)
Maybe this is what they are referring to: https://github.com/espressif/ESP8266_RTOS_SDK/tree/d47d527e0502595700db7b8c468a691c537f6d0b/examples/wifi/smart_config

How to send Arduino serial monitor data to a webpage using esp8266?
1) The first one is the ESP8266 rtos sdk ( https://github.com/espressif/ESP8266_RTOS_SDK ) I wouldnt recommend this approach for you, as you already work with an Arduino libraries. So with the bare esp8266 rtos sdk you have to do more to achieve your goal.

Redis Re-Implemented with SQLite
I'm waiting for someone to implement the Redis API by swapping out the state machine in TigerBeetle (which was built modularly such that the state machine can be swapped out).

The Fastest and Safest Database [video]
I fully agree with what Prime says at the end - Joran has really set a new bar here for all future database presentations.
Hearing that the entire TigerBeetle domain logic lives in a single file [0] (and is intended to be pluggable for other OLTP use cases!) makes it 1000% more tempting to spend the weekend getting up to speed with Zig.

Building a Scalable Accounting Ledger
Why would you want to build your own accounting ledger from scratch? Accounting is a completely new domain for most engineers, and TigerBeetle (https://tigerbeetle.com/) already solves this problem.

The Raft Consensus Algorithm
Maelstrom [1], a workbench for learning distributed systems from the creator of Jepsen, includes a simple (model-checked) implementation of Raft and an excellent tutorial on implementing it.
Raft is a simple algorithm, but as others have noted, the original paper includes many correctness details often brushed over in toy implementations. Furthermore, the fallibility of real-world hardware (handling memory/disk corruption and grey failures), the requirements of real-world systems with tight latency SLAs, and a need for things like flexible quorum/dynamic cluster membership make implementing it for production a long and daunting task. The commit history of etcd and hashicorp/raft, likely the two most battle-tested open source implementations of raft that still surface correctness bugs on the regular tell you all you need to know.
The tigerbeetle team talks in detail about the real-world aspects of distributed systems on imperfect hardware/non-abstracted system models, and why they chose viewstamp replication, which predates Paxos but looks more like Raft.

CWE Top Most Dangerous Software Weaknesses
> There is no reason to use a memory unsafe language anymore, except legacy codebases, and that is also slowly but surely diminishing. I'm still yet to hear this amazingly compelling reason that you just need memory unsafe languages. In terms of cost/benefits analysis, memory unsafety is literally all costs.
Tell that to the authors of new memory unsafe languages (like Zig) and creators of new project in those languages (like https://tigerbeetle.com) :(
