It’s a desktop app, but can sync with self-hosted cloud servers. It’s also literally just text/markdown files.

For sure, but as long as clickbait works they’ll keep doing it.

I mean yeah, but why? Like what did you like about it?

If they had made the deck more powerful, the old ones would suddenly have been obsolete.

I’m pretty sure it has more to do with current chip technology not actually changing that much in the, what, 2 years since the deck first released?

Also obsolete is a pretty strong word for what - if it had stronger internals - would likely end up being more expensive than current models.

To be fair, “an entire x” does have markedly different connotation than “x”. The emphasis is that it’s, well, the entirety of x. It’s the difference between “i ate the cereal” and “i ate all the cereal”.

Claymore (the end was kinda mid)

Genuinely curious - why do you like it? I see this at the top anime of all time. I watched it a few years ago and i thought it was absolutely horrible. Like 2 or 3 out of 10.

I feel like the only reason i can see is “the main character is a bad guy” but that doesnt excuse trope-y terrible writing, flat characters, and mid-2000’s animation that aged horribly. Am i missing something?

Make them optional lmao. I dont have a 4k screen, havent ever had one, and wont buy one for a very long time. Why am i storing these assets i will never use?

Honestly, it’s because a bunch of programs i used disappointed me (performance, functionality, [being a web app at all], etc.) and i figured it couldnt be that hard to do it better. In some cases i was right, in most i was wrong. As it turns out though, I really like programming so i guess i’m stuck here

I mean to be fair, those errors arent really meant for you (the end user) in the first place.

I’m not sure I understand your point about fall through having to be explicit

As far as i understand it, every switch statement requires a break otherwise it’s a compiler error - which makes sense from the “fallthrough is a footgun” C perspective. But fallthrough isnt the implicit behavior in C# like it is in C - the absence of a break wouldnt fall through, even if it wasnt a compiler error. Fallthrough only happens when you explicitly use goto.

But break is what you want 99% of the time, and fallthrough is explicit. So why does break also need to be explicit? Why isnt it just the default behavior when there’s nothing at the end of the case?

It’s like saying “my hammer that’s on fire isnt safe, so you’re required to wear oven mitts when hammering” instead of just… producing a hammer that’s not on fire.

From what i saw on the internet, the justification (from MS) was literally “c programmers will be confused if they dont have to put breaks at the end”.

the ergonomics expected of modern languages.

As someone learning c# right now, can we get some of those “modern ergonomics” for switch statements 💀

I cant believe it works the way it does. “Fallthrough logic is a dumb footgun, so those have to be explicit rather than the default. But C programmers might get confused somehow, so break has to be explicit too”

I miss fallthrough logic in languages that dont have it, and the “goto case” feature is really sick but like… Cmon, there’s clearly a correct way here and it isnt “there is no default behavior”

Generators probably. It’s the one thing i genuinely miss about python when i work in rust.

Ick. At the very least, i’ve seen it a LOT less in VSC. The fact that something as simple as rainbow brackets uses the freemium model in intellij sucks. I mean the fact that it’s not a builtin setting is dumb too but that’s beside the point

I feel like it’s like pointers.

“Variable” refers to the label, i.e. a box that can contain anything (like *ptr is a pointer to [something we dont know anything about])

Immutable describes the contents, i.e. the stuff in the box cant change. (like int* ptr describes that the pointer points to an int)

Rust makes it very obvious that there’s a difference between constants and immutable variables, mainly because constants must be compile time constants.

What do you call it when a variable cant change after its definition, but isnt guaranteed to be the same on each function call? (E.g. x is an array that’s passed in, and we’re just checking if element y exists)

It’s not a constant, the contents of that label are “changing”, but the label’s contents cant be modified inside the scope of that function. So it’s a variable, but immutable.

Saying “non negotiable” doesnt actually hold up in small claims, nor against basic resistance in most cases.

Look up your local laws, in some places carpets must be replaced at the expense of the landlord every X years, or if there is any kind of damage (caused by regular wear and tear) that could be a trip hazard. Pictures from move-in, carpets not being replaced when you moved in, etc. all help your case.

Last place i lived, I spent 30 minutes arguing on the phone with my previous landlord over flooring and got my 700 dollars back. Turns out most of the time they only vaguely know the laws they’re quoting, so if you come with confidence, prep, and a willingness to take it to small claims, they’ll fold to save themselves the effort.

The freemium and constant “are you sure you dont want to pay?” from some intellij plugins is insulting enough that it’s hard to believe any developer would praise it. Presumably this doesnt happen in vscode because it cant happen in vscode, not because people arent shameless enough to do it there.

That depends on your definition of correct lmao. Rust explicitly counts utf-8 scalar values, because that’s the length of the raw bytes contained in the string. There are many times where that value is more useful than the grapheme count.

I think it was this issue. Looks like maybe it got fixed some time this year? Iunno, i’ll look into it at some point

code that’s been written today has been made obsolete by a language feature in the latest nightly build

I mean couldnt you say that about any language? There’s lots of old C code that’s obsoleted by features in C11. There’s lots of stuff written in python today that’s obsoleted by stuff in the 3.13 alpha. It’s just kinda how things go.

Doesnt the edition system prevent this from being too big of an issue anyway?

I did not dismiss it, I said measure the performance yourself.

Then why does anyone ask anything? Just figure it out yourself. Oh you read a book or went to college? Why? Should have just reinvented computers yourself man. Taking advantage of collective knowledge is for suckers /s

This means that the code performance is highly dependent on runtime conditions, and needs to be measured in the place where it’s used.

How is that helpful for OP? For example, if his question was about rust i’d say “options 1 or 2 should be identical for speed”, but if it’s python i’d say “match statements are just chained if/else chains, so a direct array index would be faster”. For another example, in python attribute access is a function call. x.y in a loop is slower than assigning z = x.y outside of the loop and calling z in the loop.

You can absolutely generalize and have rules of thumb for performance.

If they already measured, then they would know which one is faster, because they measured it.

Measurements can have unintuitive results based on the dataset used (which, for benchmarks, usually end up being artificial datasets). OP’s measurements may not have been consistent with their working understanding, thus they ask outside sources to confirm the truth. Idk why you cant just give them the benefit of the doubt and like… answer the question they actually asked? The explanations for “why” that accompany that answer can also be incredibly helpful.

And all of these optimizations are just as effective after you measure them to see if they’re needed, and they’re no longer premature.

That implies that these optimizations are harder than doing it the “mundane” way. They’re not.

Here’s a fun micro optimization for compiled languages: on modern CPUs

x = x * (arr[0] * arr[1]) in a loop has better performance characteristics than

x = (x * arr[0]) * arr[1]

even though they do the same thing (in short, it’s because of the data dependencies for out-of-order execution - compilers wont make this optimization automatically for floats). How much harder is it to write the first one compared to the second one? How much harder to read is the first compared to the second?

So why would you not just make the first one your default? Now all your future uses of that pattern will perform better, for no extra effort except the amortized cognitive fee of changing your default option.

Look at OPs question. Could the answer fall under a rule of thumb that they can apply as their default option for a scenario? I’m pretty sure it can. So who cares about “premature” or not?

The particular question asked by the OP is very very unlikely to have any significant performance impact at all, unless it’s in an extremely hot loop running millions of times per frame

So instead of answering their question, you assume it isnt impacting performance and they’re just asking for no reason?

I literally had this exact question about python like 8 months ago. I had a file parser that needed to process different chunks based on a tag. Performance was critical, several thousand files, each ~3mb), the tag dispatch happened about 100,000-300,000 times per file. The original was implemented with if/else. I switched it to match because i thought it was faster, it wasnt. I looked at a lot of threads with answers like yours until stumbling upon dictionary dispatch (i.e. key = tag, value = first class function to call on the tag’s data) and array dispatch.

That change alone was a 15% performance improvement.

You have no idea how their program works, what their hot loop is, if they’re just asking out of curiosity, whatever. Just answer their fuckin question my dude. Platitudes are a waste of everyone’s time.
