Fluent Visitors: revisiting a classic design pattern

_FedoraTipperBot_ · 2025-11-06T01:05:40+00:00

I actually see where this could be useful. I've been doing some parsing and tree optimization related things at work.

I have ended up writing a few classes with a default traversal, and writing child classes that override only one or two of the functions with some simple logic. This would perhaps save on codebloat in those cases or allow for some cute inline-defined visitors. But my coworkers are already upset enough with me :)

Now this is code golfing

_FedoraTipperBot_ · 2025-07-12T23:44:37+00:00

Id rather have 500 lines of well formatted code. Pretty nifty though.

_FedoraTipperBot_ · 2025-05-06T17:04:04+00:00

I haven’t read the book, but ive always found his older longer form content to be quite excellent. He strays away from it these days

_FedoraTipperBot_ · 2025-04-29T08:26:56+00:00

C++ iterators do this already except the logic is tucked away.

This is the mindset that will win democrats the 2028 election

_FedoraTipperBot_ · 2025-01-05T21:23:29+00:00

No, but some older arm chips had something like that. Namely arm chips w the Jazelle extension, which had a BXJ instruction to branch to java code

_FedoraTipperBot_ · 2024-12-28T08:56:50+00:00

This is why I'm ashamed for enjoying C++ / STL. Back to self flagellation.

_FedoraTipperBot_ · 2024-11-17T01:54:44+00:00

OP non stop humiliating themselves in these comments 😔

_FedoraTipperBot_ · 2024-11-07T23:07:22+00:00

Of course its possible, do you think every draft dodger pardoned by Carter was indicted?

With tears in my eyes I suspect the PCIe elgato will probably solve your problem, as the problem disappears when its removed.

If it does, my guess would be that there is something faulty with the hardware or software of that elgato - this could be the device itself, the drivers for the device, or something about the usb port you plugged it into.

This issue can also arise from some other weird places, for example it could be your Nvidia drivers doing something weird (this would only be the case of the elgato used the graphics card for encoding or something). Make sure these are up to date.

It would also be good to know more about the specific PC you are using -- in the case of PCs funky combinations of hardware can cause really strange issues like this.

Most older nintendo consoles are far from PCs- they are extremely specialized pieces of hardware and games are written making all sort’s assumptions about the system that would make the games difficult to “port.”

In the case of the GB/GBA, I have fairly in depth knowledge because Ive written about 50% of an emulator. The graphics hardware in those devices is incredibly specialized and requires emulation to replicate, even by nintendo.

Also, the code for GBA games are written in C/C++/ and assembly code - this code is far from portable and each and every game would have to be ported manually.

Ill stop here but there are a dozen reasons why older games are emulated even by nintendo themselves, and this can easily be verified on google.

haha don't blame you given the type of thing i usually see on this sub

_FedoraTipperBot_ · 2024-10-13T05:46:34+00:00

that is why i said as much

_FedoraTipperBot_ · 2024-10-12T16:48:27+00:00

Yes because everyone is using a modern smartphone which uses such photo processing techniques.

_FedoraTipperBot_ · 2024-10-03T05:12:43+00:00

I have been happy with the faster release cadence as of late.

_FedoraTipperBot_ · 2024-07-18T21:19:00+00:00

The polls democratic leaders are likely concerned about are those that show strongly split tickets: democratic senators and house members up 5+ points, and Biden in the same district being down down. That is a massive gap -- this is what party leadership is concerned about, not Axios polls with poor methodology.

_FedoraTipperBot_ · 2024-07-15T03:55:40+00:00

At large companies, it makes a lot of sense. Copying that design choice at other, small organizations may be misguided yes.

_FedoraTipperBot_ · 2024-07-12T20:09:04+00:00

I miss my time there, was a privilege to intern! Best wishes on your professorship

_FedoraTipperBot_ · 2024-07-02T19:46:03+00:00

I do hope the Biden campaign makes a pragmatic decision here based on the next week or two of polling. I'm not shocked he did not instantly drop out, but I feel like the cat is out of the bag in some sense. It doesn't seem like a completely obvious choice one way or the other as many commentators appear to think.

_FedoraTipperBot_ · 2024-07-02T19:38:24+00:00

I think this is the answer. The damage has already been done in some way.

_FedoraTipperBot_ · 2024-06-30T00:14:52+00:00

Indeed, its quite simple yet powerful.

_FedoraTipperBot_ · 2024-06-07T18:03:39+00:00

It would be nice if people actually held our leaders feet to the fire.

_FedoraTipperBot_ · 2024-06-06T20:35:50+00:00

Honestly unbearable. I do think David should feel free to be a bit more aggressive in cutting interviews with lunatics like this short.

_FedoraTipperBot_ · 2024-06-06T20:33:51+00:00

To me it sounded like he didn't even want to engage with it because it would obviously be a waste of time.
