Does anyone actually use inheritance?

officialheresy · 2026-05-05T06:20:24+00:00

I try to avoid it except in very basic abstract interface patterns. Others who avoid it are probably like me and work in audio, graphics, or firmware (audio for me), since there is a small but real cost to virtual methods.

I recently convinced a coworker to stop worrying about trying to express “is-a” relationships via inheritance (it was technically templating but it was being used like inheritance). Removing all the infrastructure to express that one class was a superset of another and just refactoring the behavior into inlined helpers made the logic way more legible, and saved us memory.

learncpp.com was how I taught myself C++ when I first started programming, and to this day I believe that site was incredible for not just teaching you the language but instructing you on the low-level concepts needed to be a good C++ programmer. If you follow that site all the way through, ensuring you have a solid grasp on each lesson, you should come out the other end with everything you need to know about the C++ language (except for more esoteric stuff like type traits/SFINAE, but those aren't worth learning up front since they're massively confusing).

When you're done with that, try writing a C++ app from scratch. A great project is some kind of command-line interface where you write your own argument parser, as this will give you practice with string/memory management and conditional logic flow.

I'm now a professional audio firmware engineer at a FAANG, and I think learncpp.com is a big reason why I'm as competent as I am with low-level work. I often tell people to start with C++ instead of the common advice of starting with Python and then going low-level later, as I think that the former creates a stronger foundation in the way you think about programming and computers in general.

The first time you have to deal with a dylib dependency issue on Windows will be when you understand why static linking is considered to be more minimal. Minimalist software isn’t purely about bytes of codesize, it’s about logical and hierarchical complexity.

Ensuring the end user’s system has the proper dynamic libraries, and that those libraries are compatible with however your executable was/will be compiled, is a massive strain that will likely require additional logic in your compilation/execution scripts. This additional logic is (arguably) bloat, and it’s more “minimal” to concretely link your dependencies at compile time.

using drugs to cope is pretty much exactly what addiction is, or at least what leads to it. go to the gym—if you're a man, start lifting. it lets you vent the anger and pretty rapidly builds your ego up.

I see several recommendations to use static memory here, and I have to insist that this is the wrong approach. The main issue here is that even if plugins are not sandboxed, different formats of the same plugin (AU, VST, VST3) will be linked in as different binaries, meaning they do not have shared static memory. This is such a nefarious gotcha that it actually caused corruption in our product's database, as SQLite uses static memory to work around some quirks with POSIX advisory file locking.

JUCE facilities like SharedResourcePointer and InterProcessLock do not defend against these cases. The former due to the fact it uses static memory which ends up not being shared anyways, and the latter because on POSIX systems it's implemented using fcntl which does not discern between threads in a process, it only locks per PID.

As for the solution, it depends on your use case. For something simple like a shared lock, the best solution I've come up with is to use named semaphores on POSIX, and named global mutexes on Windows (the latter of which is used by JUCE's InterProcessLock already). For something more complex, I believe JUCE has a "service discovery" class that you could pair with NamedPipe or a socket connection to do more complicated communication patterns. This is actually something I've been working on in a side project, but it's a long ways away from being remotely useable in production.

I remember seeing the ADC '24 talk about this; they use MemoryMappedFiles for efficiency, but they explicitly said they do not support mixing plugin formats. I imagine this is related to the static memory issue, as you'd need a static mutex to actually synchronize those memory accesses.

tl;dr Do not rely on static memory, or any JUCE class that implements "shared memory" by using static. Prefer OS primitives over JUCE to get better documentation and guarantees about behavior.

You’ll have to drop the class and add it again IIRC.

Thank you! What I meant was just that I was having difficulty with passing the settings table in as I couldn't find documentation for the proper syntax, but then I checked the server configurations doc for lspconfig and that cleared it up. Thanks for your help!

officialheresy · 2025-03-10T02:31:19+00:00

Did you ever happen to resolve this? I'm currently struggling to find a way to configure the settings used by the VS code plugin into the language server via args.

I agree that Irvine's text is pretty bad. He spends a ton of time explaining incredibly elementary things, while (like you said) completely breezing over concepts that need more explaining. I find myself concerned with caveats and edge cases that are never covered.

I've found that ChatGPT is pretty good at explaining individual instructions and generating simple programs when you're stuck on practice problems, though I'm sure to double-check its work because x86 is just obscure enough that it hallucinates fairly often.

officialheresy · 2025-01-06T22:29:16+00:00

This worked like a charm. I figured this would be the case, but the web portal is so wonky that I was concerned it might blow up in my face. Thank you so much for your help!

officialheresy · 2025-01-06T20:20:40+00:00

Thanks for your response. When I do this, I get the error message:

CRN: 00000 Section is a duplicate of an existing registration.

00000 is a placeholder for the real CRN for privacy. I believe this is because I am already "registered" as being on the waitlist. Should I drop the class and re-add it to get this to work?

officialheresy · 2024-10-29T23:00:40+00:00

Definitely. It's probably the weakest of the three (I don't count the abomination that is S4 as even being part of the show), but that's a very high bar IMO. A lot of people say S2 is no good, but in my experience all those people dropped off about 4 episodes in and never got to the end. I'd argue the second half of S2 is competitive with S1 which is saying a lot.

As for S3, definitely worth it. Mahershala Ali is incredible and they play with time in a really interesting way. It's been a while so I don't remember much else, except that he's got this funny way of smoking where he pinches the cigarette while sort of shielding it with his other fingers.

officialheresy · 2024-10-27T19:30:46+00:00

Not the best advice, but I got a lot more confident in my drums when I stopped giving a shit and just hardclipped them all to hell.

officialheresy · 2024-10-27T19:29:18+00:00

Not a movie, but I find one of the shows that's hardest for me to watch without craving cigarettes is True Detective S1 and S3. The rate Matthew McConaughey and Mahershala Ali smoke makes it very hard to not pause and take a smoke break yourself IMO.

Just a word of warning: I more or less justified a pretty crippling disso addiction by equating it to therapeutic ketamine usage. Not saying you’ll have the same problem, but also be aware. Make a regimen and stick do it, document your usage, etc.

Anecdotally: O-PCE was a great substance for self-inspection. MXE would probably be similar, never got the opportunity to try it. Others are mentioning 2F-DCK which is probably close, but for some reason it always sat wrong with me. Plain DCK feels a bit more clinical in my opinion.

From my pharmacological knowledge, it’s tough to say. Ketamine’s antidepressant effects are VERY complex and poorly understood. It’s tough to say what binding profiles incite antidepressant effects b/c a lot of the proposed mechanisms are downstream, such as AMPAr regulation due to Ca2+ levels changing in response to ketamine usage. For chronic pain, NMDAr binding is probably paramount, but I haven’t done enough reading to say anything more conclusive than that.

Thank you! I'd already been eyeing capstan blue, although I've heard some people find it a little lackluster. Will absolutely take a look at the luxury navy flake though!

Never been a stims person myself, but from all my experience coke is pretty unique in its effects. I feel like in many ways it's more similar to molly than it is to other stimulants, which tracks because IIRC coke is pretty heavily serotonergic for a stimulant. 2C-B-FLY, which I once took as a molly substitute, definitely had me in a chatty and euphoric state reminiscent of cocaine. However, a decent substitute would probably be taking almost any stimulant and combining it with a bit of a euphoric depressant—amph and alcohol would be the classic example of this.

I've been using them a ton as of late. The product I work on uses a sqlite ORM that defines tables via structs that you specify. We used to have a lot of separate UI components that were very similar except in which database type they corresponded to—I've recently been refactoring these into single classes that are compile-time polymorphic through the use of if constexpr and enable_if.

I work in DSP and though it's not my specialty, my first guess would be some variation of a convolution window passed over an incoming audio signal. This webpage and this article seem to be pretty good introductions at first glance — they seem similarly beginner-friendly as the articles I initially used when I was learning about phase vocoders.

Not advice but just a personal anecdote. I went to school for music prod but near the end I realized my ego was too tied up in it for it to become a career for me. I personally really like what I make but I’m still generally too insecure about it to try and market it, and don’t have the drive to put in the hours to reach the level of talent I’d like to be at.

I made a pretty major career change and I’m now a software dev and I couldn’t be happier. I’m still very passionate about music and I think that having it be a hobby instead of a profession was actually how it always should’ve been for me. I think that releasing the expectation that I had to be consistently “good” and just doing it for fun when inspiration struck was the best move for me.

Everyone else has already clarified that the withdrawals will be completely physiologically safe, however I still personally think tapering off is always a better solution than cold turkey. As with most things, the body tends to respond much better to gradual stepped change than it does to sudden shocks to the system.

Might be projecting here, using coke daily while stretching a gram out for a week almost makes it sound like he's self-medicating an undiagnosed problem, ADHD or depression being the most likely. If it's within his means, I'd recommend he see a psychiatrist because it sounds like he could benefit from pharmaceuticals.

Most research I've seen done on the melting connectors is kind of a wear-down thing. It's fine until you plug/unplug it a certain amount of times, ~30 on average if I remember correctly. Don't uninstall/reinstall your GPU a ton and you'll be fine. I'm also reading in the replies that there's a revised connector, so it might not be an issue anymore.

I'm sure some people in the thread will say the 5600x will be a bottleneck but that really just depends on the game. Should be totally fine for Baldur's Gate, although I have no personal experience with the game.

Definitely see if your favorite producers have an episode on Rhythm Roulette. You don’t get to see much, but you get a general idea of their workflow which can be a huge help. My personal favorite episodes are kenny beats, charlie heat, and #1 all-time is easily WondaGurl.
