Hey you! Yes, you Lightning dev! We heard you were worried about the safety of your user’s funds stored on your Lightning node. It’s a hot wallet after all, and we all know that’s a big no-no for storing large sums of satoshis. That’s why VLS exists. VLS separates Lightning private keys and security rule validation from the Bitcoin Lightning node to a separate, secure signing device. What’s that? “Sounds great, how do I start?” you say? ...
I had previously completed Google Summer of Code | 2021 and Linux Foundation Mentorship | 2021 two highly renowned open source programs which paved my path towards excellence as a software developer. I chose open source for reasons I have highlighted in Collaboration not Competition but it brought so many other good things along with it like learning, friends, experience, connections, etc. There was one space which was left for me to explore with open source, Bitcoin. Summer of Bitcoin started when I did my GSoC and the next summer (2022) again I didn’t apply because I was focused on my internship at Microsoft to grab that P.P.O. and chill for final year. ...
Why to Rate Limit? Rate Limiting is a crucial part of designing any API it maybe private or public. A rate limiter caps how many requests a sender can issue in a specific window of time. A rate limiter provides following features: Defense against a Denial of Service from malicious actors trying to pull down the service. Ensures the load on servers is always under maintainable state by discarding too many requests. Prevent broke developers from receiving an unexpectedly large bill in today’s auto scalable cloud service offerings. I can relate with you Max :’( ...
Let’s take an example of operating system information as a data structure to better understand sum types. Struct Our bare minimum struct to represent an operating system contains a few common fields that would exist in each of the operating system. typedef struct { char organization[]; int releaseYear; float version; int is_opensource; } os; It’s missing one thing though the type of operating system like macOS, linux, windows, etc. Enum We will add in a new field into our structure to represent the type of operating system by using an enum. ...
Coroutine A coroutine is an instance of a suspend-able computation. It is conceptually similar to a thread, in the sense that it takes a block of code to run that works concurrently with the rest of the code. However, a coroutine is not bound to any particular user level thread. It may suspend its execution in one thread and resume in another one. This scheduling of coroutines is handled by the Kotlin dispatchers similar to go runtime ...
Financial System Bitcoin is a financial system created to serve a highly political intent, a free and uncensored network where all can participate with equal access. It is a mechanism of organizing people and computers to make one immutable, digital document. Bitcoin Offerings Bitcoin doesn’t keep track of the identities of the people (or machines) that use it making it permissionless. It doesn’t increase the supply of bitcoins to meet demand making it deflationary and inviolate. It doesn’t force itself on anyone making it consensual. It doesn’t exclude anyone from using it making it inclusive. It is well enough that people of the nation do not understand our banking and monetary system, for if they did, I believe there would be a revolution before tomorrow morning - Henry Ford ...
A goroutine is a lightweight thread of execution managed by the Go runtime. To start a new goroutine we use the go keyword go f(x, y, z) The evaluation of f, x, y, and z happens in the current goroutine and the execution of f happens in the new goroutine. Goroutines run in the same address space, so access to shared memory must be synchronized. The sync package provides useful primitives, although you won’t need them much in Go as there are other primitives like channels. ...
TL;DR and not for the weak hearted, please don’t start reading this until you are willing to put efforts into changing the way you deal with online subscriptions. Childhood Fun Since my childhood I was taught by my cousin brother (Karan) on how to utilize the amazing peer to peer network named torrent we used to keep our systems running late at night to just download a video game, dark ages I know. ...
Gold Plated Products Gold Plated Products is what am calling products/services that get offered as free or for unlimited usage to get numerous people onboarded on it. After a while either they will add a paywall for complete service or some premium features which were previously free are now only available if you pay. The issue begins when there is a lack of information provided to users of when the paywall or premium offering will become active. The Product Managers just wake one day and decide to choose violence, boom the paywall goes live. ...
