Copying my comment from another article: This time I used VSCode for nearly 2 months. Thought it's the end of an era, I'm not coming back to Sublime Text. I decided to push through and customize the configs just right for me, it w

I agree that some claims about e2e are misleading. That said, you could interpret "mathematically impossible" very charitably as risk assessment math. It's mathematically impossible to improve investigability while also impro

I gotta admit, perhaps a bit naive of me, that the concept of "tech charlatans" didn't click for me until now. It's true, they are out there, and I see it now. I mean, I know there are phone scammers, but they probably b

I considered that, but couldn't find a way to precisely control amount of RAM used when you read from it.

Are you saying that the file would just entirely be loaded into a page cache eventually? I imagine, even if true, it still wouldn't result in OOM killing the server/worker daemons on account of this data?

I'm no systems programmer, but I remember trying to research mmap approach. It's been 3 years, so I'm not sure what stopped me, but something didn't feel right. Perhaps it was the lack of control over how memory is used.

Not 100% what the article is about, just a short story. In one of my old jobs we had megabytes of infrequently accessed static key-value data. If we simply loaded it into a const (i.e. a hash table), it would blow up the RAM so much, that w

To be frank, alcohol, most drugs, and fat are not the same. Every time I go to a place where smoking is not culturally frowned upon, I can't make a few steps without inhaling vomit-inducing smoke. If it wasn't for this, then I wou

The truth is, this does happen, but you want it to happen less. Banks accept certain amount of risk due to logistical limitations, but always seek ways to reduce it.

This is a good explanation for Bitcoin-type ledger, but as far as I understand, banks don't share a global ledger. In US they run settlements through FED, which is the closest thing to global ledger we got, but internally they keep the

This is a checksum-like trick for manual record keeping, and isn't specifically relevant to the grandparent. It isn't required in digital world. The grandparent talks about having to write 2 separate transactions in 2 accounts in

In most cases microservices are an anti-pattern, because they are trying to solve problems that can be solved without incurring their complexity and sacrifices. However, I remember that Sagas originally were proposed to deal with multiple 3

The difficulty is different. Front-end is very capricious, idiosyncratic, inconsistent. You have to deal with lots of annoyances, puzzles. You still might have some connectivity responsibilities, like restoring a web socket connection, mana

You're the reason I wrote "split _almost_ perfectly". That said, looks like your history involves .NET -> Python/.NET. I went .NET -> PHP -> Ruby/Elixir/Go. It took me some time to withdraw from .NET b

What's missing here is the programming language. There are incredibly flexible, concise, low-ceremony languages, with implicit types where placing an IDE between you and code kinda obfuscates them. These are the languages where I think

The first 3 sentences of the article are implying that the whole thing is written with "if you must" attitude. That said, a lot of companies have front-end teams, and those front-end teams commit years to building React components

Huge scale typically leads to the opposite: more backend generalization, not catering to a specific front-end. That's why Facebook built GraphQL — because they run on anything, like fridges, TVs. That's specifically an attempt to

I'm suggesting to pass via JSON what we used to pass via HTML back when front-end was templates on the server. I still prefer those days, like I alluded to in the first paragraph of the article. It used to be: write your template by in

Have you looked at this from the angle of object constructor or function parameters? Let's say you build an object called Person. They have first_name, last_name, phone_number. That's what you probably will pass into a new Person.

Author here. Here's an additional piece of wisdom that I picked up in over 20 years of doing this. Reliable communication allows for simpler, less coupled interfaces. Unreliable communication demands increasingly elaborate and coupled

For reads and offloading front-end work, I think the article's approach should be good for your use case. Just make sure that your backend code is cleanly written. Create proper domain objects to represent pages that you will be servin

The "page" becomes the resource for reads. You get great scalability, because you can use your database in the most efficient way possible to provide entire data for the page. You can maintain 100% back-end clarity on what each pa
