But you can’t look at a method signature and instantly know who handles the null check. You need to inspect code and calls to know for sure. This will lead to paranoia, sooner or later

The problem is that when an project is too big and a method is called from multiple contexts it’s very easy to lose track of the context where the null check has been done and where it hasn’t. This leads to a lot of duplicated null checks around the project and the constant paranoia of “can this be null here?”.

A much better way of doing this is using the Optional when an Object can be “null” and a direct instance where it cannot. This way, at any given context you know for absolute sure if a null check is needed or not. However, even with annotations this does not throw a compile error…

I want to write functions that fail at compile time if called with a null object. You can use annotations to kinda do this, but they do not produce compile errors.

It’s single thread, one file at a time.

I was told the show is very popular in Australia, is that true?

I don’t really mind the contestants outside Europe, I think it’s pretty cool they invited Australia if Australians are indeed fans of the show.

I feel ashamed that my country is not on this list.

Fair point.

We also have a 20 square meter study where we installed AC. The unit cost around 550 euros and installation was like 70 euros cheaper. Total cost was cheaper but still hard for a median family to support.

Most families use some sort of fan or cooling column but they are quite lackluster and only work in summer.

My living room is around 36 square meters and the cheapest AC unit for that area was 650 - 850 euros. You also have to pay a certified company to install it, which cost another 200 - 300 euros.

The median salary is like 900 euros, which makes it out of reach for a large portion of the population.

Self hosting an email server is a pain in the ass and I don’t really recommend it.

Buying your own domain and using it in whatever email provider you want is very easy and gives you ownership over the email address. You may switch providers freely without needing anyone else to do anything.

That’s unfortunate :(

Is .dev maintained by the US?

Compared to the software we were using before such as Skype, TeamSpeak, Ventrilo and Mumble… The UI is amazing.

I’d happily move to Matrix but I’d lose all the servers for my hobby interests. No point in having both.

I’ve been using it for several years. I have a small server I use with my IRL friends and it works great.

• Near 100% availabily
• Nice sound quality
• Supports multiple servers for your multiple interests
• UI is amazing
• Works fine on every platform
• Screen sharing / streaming is easy
• Cool to see what your friends are playing
• Free plan is more than enough, you can pay for cosmetics or higher stream quality.

There are dozens of us!

Is there a (Linux) command I can run to check my power consumption?

especially if you’re looking for a physical gift

Yep, it’s a git! :)

The short term goal is only to learn the absolute basics of programming. I only mentioned GIS to give some context on why I was narrowing down the language to python.

She’s familiar with all the keywords you mentioned as she already works in GIS, just not as a developer.

Looks great, thanks a bunch! EDIT: ordered it! :D

The only one pretending mistakes can’t happen is the person I replied to. Mistakes definitely can happen and no programming language is fool proof.

Continuing my car analogy, would you rather drive a car with airbags and seatbelts or one without them? Of course you can still have a fatal accident, but it’s nice to have safety features that make it as unlikely as possible.

Every car has airbags if you drive well enough. Right?
