My guess is that next the language gen will be languages that AI generates, which are optimized to be readable to humans and writable by AI. Maybe even two layers, one layer that is optimized for human skimming, and another layer that actually compiles, which is optimized for AI to generate and for the computer to compile.

Lvl999Noob · a month ago

For the current category of LLM based AI, "AI optimised" means "old and popular". Even if you add a layer that has much more details but may be a lot more verbose or whatever, that layer would not be "AI optimised".

My problem with C++, and maybe this is just me, is RAII.

Now, Resource Aquisition Is Initialization is correct, but the corollary is not generally true, which is to say, my variable going out of scope does not generally mean I want to de-aquire that resource.

So, sooner or later, everything gets wrapped in a reference counting smart pointer. And reference counting always seemed to me to be a primitive or last-resort memory managment strategy.

Lvl999Noob · a month ago

Instead of reference counting, consider having two types. An "owner" type which actually contains the resource and the destructor to dequire the resource. And "lender" types which contain a reference (a pointer or just logically (e.g., an fd can just be copied into the lender but only closed by the owner) to the resource which don't dequire on destruction.

Same thing as what Rust does with `String` and `str`.

So are we also going to have team themes, team syntax highlighting colors, team fonts, team dark/light mode, team screen resolution, etc?

Why not bikeshed the bikeshedding?

Lvl999Noob · a month ago

FWIW, team screen resolution is pretty much already there when the company provides the laptops (+ screens).

How would the database know whether the other app layers depend on that value or not? You could absolutely have an app that does not require data in a specific field to function, yet all records happen to have data. This is actually fairly common in single-tenant apps, where some tenants populate a field and others do not. You need to look at how the data is used across the entire stack to know whether or not it should be nullable, not whatever the current data happens to be.

Lvl999Noob · a month ago

The script example in TFA is just a starting point. I believe you would still manually go through all the columns it finds and decide which ones are actually supposed to be nullable and which ones don't need to be. As the article said, nullable fields that don't contain null could be a sign of incomplete migrations and such.

> you need a concept of absence that's different from null

Could you give an example? Null _is_ absence, the way I see it

Lvl999Noob · a month ago

What they are saying is that the field is always present in the domain model but we don't have the information to backfill it. For example, say you have a customers table. Originally, it just stored their name and internal ID. But now you are adding in their government ID as well. Except that you already have thousands of customers and you don't have their government ID. So you either make the column nullable and slowly backfill it over time. Or you find some default value which isn't null but the code understands it to still be empty. And again, you slowly backfill over time.

1. Frequent service (<5 minutes between buses, ideally) 2. Enough capacity to support rush hours (so each bus can straight up refuse to take extra passengers) 3. Education campaigns and police / fines / other external factor for the short term (to break existing habits) 4. Separate public transport lanes so buses don't get stuck in traffic or behind red lights.

IMO, these are sufficient for a good public transport system. Skipping stops is the worst since it makes the whole network unreliable.

If the above points are too high of an investment and skipping stops is the only viable solution then a proper digital interface is needed. If the schedule is dynamic then the information about it also needs to be dynamic. I need to be able to know that the bus I am on is going to skip my stop and plan my next steps while I am sitting in the bus itself.

> Having a widescreen monitor is irrelevant to me unless I fullscreen my browser (which I don't and I assume most don't).

Are you kidding? I'm willing to bet 99% of users run their browsers fullscreen.

Using the drag-and-drop feature that splits the screen between two GUIs already marks the office power user, a third windows on a single screen brings us into the territory of the hardcore nerds running tiling window managers.

Lvl999Noob · a month ago

FWIW, I run my browser full screen. I run most apps full screen. By full screen, I don't mean that weird macos thing where it removes everything and locks you into a single app in a single workspace but the more standard one where the window is just expanded to fill the screen space.

The only time I run an app without fullscreen-ing it is if I don't have to do much in it or it doesn't have enough content to use up all the space anyways. Like system settings. Otherwise, I am using the app -> I am focusing on it -> I want it to take all the space it wants and show me everything going on inside it. My browser and my text editor are apps where I spend 99% of my time so they are always full screen.

Because zero-size types exist which you might want to take the address of. Possibly as a result of macro substitution or templating mechanism that only appears in certain build configurations.

It means you don't need a bunch of special-case handling if one out of 27 types ends up with zero size in some situation. It just all works the same way. Especially the unique address part because that would be an annoying source of difficult to track bugs.

Lvl999Noob · 2 months ago

Yes. I believe zero sized types should be possible and they should all have the same address. Trying to deref the pointer is UB right away because you do not have the byte under that pointer. As it is, the malloc implementation now needs special casing for 0 sized allocations and different implementations special case it differently. C is supposed to be low level so surface this confusion up. Let the programmer decide if they want a unique address and reserve a byte or a non unique one with no overhead.

Lvl999Noob · 2 months ago

Can someone tell me a usecase where you want multiple allocations of size 0, each one with a unique address, and each one unique from any other allocation (hence necessarily removing that pointer from being allocated to anything else) but can't use malloc(1) instead?

I think it would be much better if malloc(0) just returned 1 or -1 or something constant. If the programmer needs the allocation to have a unique address, they can call malloc(1) instead.

I didn't mean the two paragraphs to imply that they are somehow opposites (though on hindsight I obviously did). There are tradeoffs. a single binary is between docker and a library that uses shared libraries. What is right depends on your situation. I use all three in my selfhosted environment - you probably should too.

Lvl999Noob · 3 months ago

If you are using docker, do you save anything by using shared libraries? I thought docker copies everything. So every container has its own shared libraries and the OS running all those containers has its own as well.
