There’s little argument that open source has transformed our world. As a developer, I cannot recall a single day in the last few years where I did not rely on open source software. I’m not the exception. The majority of software engineers today rely on open source daily in their professional lives.For one, open source is dominating developer infrastructure. From operating systems (Linux in the cloud) to databases (MySQL, MongoDB, Redis) to programming languages themselves (JavaScript, Python, Java, C, PHP). It’s not just developers, it’s consumers as well. From what they run on their phones (Android) to how they access the web (Chrome, Firefox).The motivation is clear. Open source is good for humanity. It is making technology more accessible and open — anyone can build anything.Open source (...)

Ctrl-Alt-Delete: The Planned Obsolescence of Old Coders
▻https://onezero.medium.com/ctrl-alt-delete-the-planned-obsolescence-of-old-coders-9c5f440ee68

The software industry is overwhelmingly young. The median age of Google and Amazon employees is 30, whereas the median age of American workers is 42. A 2018 Stack Overflow survey of 100,000 programmers around the world found that three-quarters of them were under 35. Periodic posts on Hacker News ask, “What happens to older developers?” Anxious developers in their late thirties chime in and identify themselves as among the “older.”

I turned 40 this October, and I have worked seven years in the same job at a database company called MongoDB in New York City. Many programmers my age have gone back to school to switch careers or have become managers. I am committed to a lifetime as a programmer, but my career path for the decades to come is not well-marked. I know disturbingly few engineers older than me whose examples I can follow. Where have all the older coders gone, and what are the career prospects for those of us who remain?

After closing their latest funding round, Redis Labs (circa $146 millions raised to date) announced new licence changes (again) to their Redis Modules. Before that we had high profile startups Confluent (behind Apache Kafka with circa $205m raised to date) and MongoDB Inc (now a public company) change their licences. These licence changes are according to their executives necessary to protect against what they perceive as unfair practices from big cloud vendors (Amazon Web Services often cited as biggest culprit) — who do not make significant contributions (or none at all!) to open source projects and yet fork projects to create competing hosted services. The following are some of the quotes from Redis Labs and Confluent executives that echo the sentiment of unfairness towards the big (...)

AWS and Mongo and Open Source

AWS and #mongodb and Open SourceMany people seem to think that the AWS and MongoDB story is about cloud providers and Open Source business models — but the core of it is in fact about cloud providers and selling software licenses. Many companies around Open Source projects make money by also selling licenses to some additional proprietary software but all companies around proprietary software sell licenses.Selling licenses is hard in the presence of cloud providers because cloud providers have a better product, they sell the whole thing, while a license is only a part of the solution. People don’t want to buy a quarter-inch drill, they want a quarter-inch hole.Let me quote Ben Thompson from the linked article:There is a secular shift in enterprise computing moving to the cloud, not because (...)

Libraries like React went from React.createClass to class MyComponent extends React.Component, ie went from rolling their own constructor to leveraging a language built-in to convey the programmer’s intent.For a Node.js web application’s persistence layer, a few databases come to mind like MongoDB (possibly paired with mongoose), or a key-value store like Redis.To run a relational database with a Node application, Sequelize, “An easy-to-use multi SQL dialect ORM for Node.js” is a good option. It allows the application to run backed by a MySQL or PostgreSQL instance and provides an easy way to map from entities’ representation in the database to JavaScript and vice versa.Sequelize’s API for model (...)

Sharding is distributing #database queries across multiple servers. Before we do that, let’s get the idea of storage engines. New in MongoDB 3.0 is that they offer pluggable storage engines. A storage engine is the interface between the persistent storage, which will call the disks which might be a solid state disk, and the database itself.So, the database talks to the persistent storage through a storage engine. Now, it may be the case that the storage engine itself decides to use the memory to optimize the process. So, in other words disk is very slow. Since the idea of databases is to store stuff (...)
