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.

Can someone please eli5 how the hierarchical timing wheel algorithm works?
I briefly described the algorithm in this article and there is a wonderful article from Kafka that goes into more depth in their general purpose implementation. My implementation is specialized and over optimized in comparison, e.g. by using bit manipulation to avoid more expensive division/modulus instructions. Tokio rewrote their timerwheel after I showed them mine, borrowing some ideas but also staying more general. Hope that helps!

I am proud to announce, a new Sorting algorithm!
AFAIK, the Linux kernel actually uses a LinkedList for this (Ref: workqueue.c, types.h) and message queues use Timing Wheel (Ref: Kafka's TimingWheel)

Open Source Analytics Stack: Bringing Control, Flexibility, and Data-Privacy to Your Analytics
With the increase in real-time data streams and event streams, certain use cases emerged that require access to real-time data such as financial services risk reporting or detecting a credit card fraud. Real-time streams can be obtained using a stream processing framework like Apache Kafka (website, GitHub). The focus is to direct the stream of data from various sources into reliable queues where data can be automatically transformed, stored, analyzed and reported concurrently.

Wizards of Opensource, Ep 1: Ryan Dahl
On 16 February 2009, a GitHub commit was made. By a person who would later turn out to be the creator of two of the most successful, impactful, and standard tech platforms the world has ever seen. Who is he? Let's explore.

Stop Wasting Connections, Use HTTP Keep-Alive
Based on several issues in the Node repository (nodejs/node-v0.x-archive#7729, nodejs/node-v0.x-archive#5488, nodejs/node#5436) this error can occur when a DNS server fail to respond, perhaps due to it rate-limiting requests. Reducing DNS lookups can reduce or eliminate these errors.

Why does RSS constantly grow when reading data from a child process and calling process.stdout.write()?
I don't know how node is processing the stream and buffering or not buffering. I just invested the past few hours into researching Node.js buffering and not buffering read(). There are more than one issue regarding the subject-matter, e.g., https://github.com/nodejs/node/issues/2972, https://github.com/nodejs/node-v0.x-archive/issues/4000, https://github.com/nodejs/node/issues/6379. From what I gather Node.js blames the process itself. However, I run the same algorithm using Python, C++, C, QuickJS JavaScript engine where the RSS does not exponentially increase during usage.

Why console.log(this) prints an empty object when used in the global context? Shouldn't it point to the global object?
...or something similar to that. I mean, it's pretty close to that. You can see for yourself if you want. These lines there are exactly what they do: They set thisValueto point to module.exports and then they execute your file/module with that as the value of this. (Only they have some additional helper stuff like ReflectApply because there are some additional complexities now with modules. In the older versions of the code you could see the apply call directly there.

Deno 1.9 – native http2, performance boost, blob and import completion support
I was referring to node <0.1.30[1] which did have promises for a while. largely from jQuery deferred, which were ungood in a couple ways I don't remember. but also remarkably similar.
I still largely think kris kowal building the "Q" promise library is what made promises interesting, what surfaced the idea that we might want to first-class our completeablea/futures. I know kris had some specific inspirations but I forget what.
pains me somewhat to this day that promises ultimately became somewhat un-value like, that handlers don't get to see what it was resolving. all the chain/spawn discussion, the functional promise folk: they got rolled by those insisting we had to target only the lowest rings of the developership, and that allowing more potent systems was unacceptable. wish I could find those es-discusa threads, for the powerful sorrow of the afteath, what we are stuck with, in it's so lites form, haunts me. especially as we double back a decade latter & invent controllers & signals toanage our promises. which we would have had for free.
way off topic now. forgive me my late night ramblings.
