You also have to calculate in the complexity of running thousands of servers vs running just one server. If you run just one server it's unlikely to go down even once in it's lifetime. Meanwhile cloud providers are guaranteed to h

The rule is: Keep related data together. Exceptions are: Different customers (usually don't require each others data) can be isolated. And if the database become the bottleneck you can separate unrelated services.

For anyone else considering to build a dictionary app, and you know a bit of HTML, I recommend making a static web site/app which uses service worker to cache all words for offline use, and web app manifest so mobile users can add the

Is there a torrent that gets updated regularly, or where/how do you download the zone files for all the TLDs? And what dns server software do you use?

In nodejs you can use the vm module. And for extra layers you can run node itself in a linux namespace aka container. Inside a VPS that has selinux. On a dedicated server with no LAN access besides the gateway. In a fireproof datacenter.

Ive had many checksum errors with ZFS, really no difference between enterprise Hdd or cheapest possible hdd (new ones). Or i just got unlucky. But some hdds are 15+ years, bad sectors but still usable.

When we are talking nanoseconds or low microseconds the distance is still important - networking has become a lot faster, but we are still talking milliseconds when doing stuff in the "cloud", if not seconds if we are talking en

A sorted list. It's often cheaper to sort the list after each change, then to search the whole list. Especially when you do collision detection in 3d... (maybe not so obscure, but at least underestimated) When I pair my socks I first p

Software costs always grow exponentially. Having 1,800 IT systems sounds silly, but combining them into one system would not take X*1800 hours, it would take X^1800 hours.

The sunk cost fallacy is perhaps the most useful thing you learn in business school. eg. Do I want to pay $9,600 to get the job finished. What would it cost if I hired someone else to finish it ? The same thing if you are going to a concert

It's corporate politics. The amount of tracking and data collected is not decided by the engineers nor the content creators. Most entrepreneurs think that the more data the better and that it somehow can be monetized in the future - a

A naive approach is to have a integer named "version" and a bool named "synced" beside each post/record/row. Then increment version and set synced=false when updating, and synced=true when synced. Or make the d

I find it interesting that some religions forbid interest in loans. I think they are into something as it's evil to first lend someone money at say 2%, then increase it to 4% interest. Inflation is created by "printing" more

In feedback like this I filter out the useful information. No need to hurt your ego, or go on the offense, if you instead respond by asking questions that show you do care and understand you will often get a more humble response.

What's even worse is that the code is used as single factor, eg. No extra security besides this code.
