pibion Make microservices look like monoliths

My goto for this kind of task is moleculer: https://moleculer.services/

Fast, battle tested, vue2-like approach, great documentation, good community. The automatic indipendent-scalability as an option is usually the main selling point of these solutions, but honestly I think the real pro is the "composition" approach, which is essential if you want to keep a clean and well-organized codebase. On this regard, I found moleculer pretty great even for large teams.

pibion Lesser-known JavaScript APIs

Intl could be considered a JS API, honestly.

But yeah, it's ridiculous still conflating the two after all these years of full-stack Javascript developments.

pibion Progressive Microservices Framework for Node.js

I'm working with microservices all the time. Even when working solo. It's easy to focus on a single domain while developing a single part of the system, just like coding modules or classes.

That said, I'm always wondering why we are conflating so many things when talking about microservices: deployment and scalability, multi-repo and code structure, integration tests and distributed transactions, and so on. I mean: you can definitely build your application as a monolithic process with a microservices' architecture. It's just separation of concerns all the way down and a proper abstraction for the communication channel between the "modules". You don't need to embed your deployment structure in your repos and your code. These are "framework" problems. Just use one that abstracts all the deployment details until it's time to push the code to prod, and you have to split your code in different containers. This is why I'm now settled on Moleculer (https://moleculer.services/). It just works.

pibion Don't start with microservices – monoliths are your friend

Well, it's all about the data responsibility: who is the owner of the data, how others can access the data. Once you have defined these, you see that you can "share the access" with other microservices (for example read only mode on a view), as long as the ownership and the access rules are preserved.

pibion Don't start with microservices – monoliths are your friend

Clarify the microservice architecture concept with "how you are going to deploy your system", as per your example, is exactly what I'm trying to explain to my teams since the microservice architecture inception. There are too many concepts conflating into the "microservice" term: code architecture(separation of concerns), source code organization, deployment, etc. This is very confusing, which is the reason why it's now common to say that microservices are "hard".

Actually useful is subjective. What's the carbon footprint of all the gpu rigs in the world used to play video games? Is that useful for you?

pibion NPM – "is-even", 160k weekly downloads

I love the fact that this small code is still wrong:

  var isOdd = require("is-odd");

  console.log(isOdd([1])); // TRUE!!

pibion JSON Schema bundling formalised

It's really not that hard-to-read or to-write. I have instructed dozens of young developers on that with almost no-supervision and no-issue. It's really pretty straightforward.

Also, I can replicate my validations at many levels down the stack: from the client to API-GW to the database model. All with a single definition.

pibion ClickHouse: An open-source column-oriented database management system

Years of daily intraday market data. We have an ingestion engine written in c# and a nodejs backend to run the queries (with an in-house driver built on top of the HTTP APIs)

pibion ClickHouse: An open-source column-oriented database management system

Actually not, but we are ingesting a whole day of EOD market data (thousands of symbols, millions of timesales, billions of books events) in less than a couple of hours. This is 4x faster than the pace of the realtime market (not counting the extended hours due to the limited volume).

pibion ClickHouse: An open-source column-oriented database management system

Great software. We are managing terabytes of stocks data and realtime market scanners queries across all market (billions of books and timesales) with hundreds of concurrent requests.

We were using kdb before, but clickhouse is more scalable, way cheaper and much more easy to grasp for a newbie.

pibion Beyond Meat’s Beyond Burger life cycle assessment (2018)

Hey, thanks. I'm aware there are so-called alternatives (Banana Blossom, Tofish and such). Unfortunately, from my experience they don't taste like fish yet.

pibion Beyond Meat’s Beyond Burger life cycle assessment (2018)

After "seapiracy" I don't really think we are addressing the biggest issue here. I would like to know if there's anything like that for fish. I would buy anything that tastes like tuna but it's fully vegetable, or any other fishes. Just give me the same taste on my sushi, please.

pibion How Nespresso's coffee revolution got ground down

Kamira works at 3 bars. It can make one or two espresso at the same time, but no more than that. The design is the opposite of a Bialetti's Moka, where the water is pouring into the coffee from the bottom. On a Kamira, the water is coming from the top, preserving the oils and the cream to being burnt.

It's also very quick, you can have your cup of coffee within a couple dozen of seconds. Not very hot in this case, but still very tasteful.

Great taste, effortless, no waste, cheap. What else?

I read on your link that average life expectancy in Italy is 83.4, about 4 years more than US (at 78.9). So I don't get your point unless you are speaking about the age structure: https://en.m.wikipedia.org/wiki/List_of_countries_by_age_str...

pibion Questions to ask before adopting microservices

I'm mostly a solo developer now, and I'm working with microservices all the time. It's very good to focus on a single domain while developing a single part of the system, just like coding modules or classes.

That's my mantra since 5 years now. Swaggerize-express or swole for the routing, but also swaggering-mongoose or objection's schema loaded from the yaml file for the database model. As a plus, validation is available out of the box.

less code, standard approach, less bugs.

BTW, I agree with the other comment that this is more common in the north.

pibion It’s All Greek to You and Me, So What Is It to the Greeks?

Italian here, we use Arab for pretty the same sentence.

That's because we are still studying Greek and Latin on some public school.

pibion Ask HN: Why are modern music players so bad at playing music in random order?

pibion India will overtake the US economy by 2030

Really? Not apples or bread? We have valleys known only for their unique apples, like the Mela Renetta from Friuli. Don't let me started talking about the apples from Trentino. So, maybe you are talking about apples in the south of Italy. About bread: I see where you are coming from, best breads I eaten are coming from bakeries on the mountains. They just taste so good. But please, remember that bread in Italy is just a support for the main tastes, like the olive oil.
