C에서 인자로 수식 들어가는거 아시죠?

int num = get_num_carrots();
printf("There %s %d carrot%s.", num == 1? "is" : "are", num, num == 1 ? "" : "s");
// There is 1 carrot
// There are 2 carrots.

`#define private public`

Why does Linux have so few debug traces in its drivers? In Haiku I can usually just enable/uncomment a `#define TRACE` and get lots of debug info from any driver I need. In Linux, they fail silently or with a very nondescript error ("spi-nor: init failed: -2" or so) and I have to spend a lot of time adding my own traces in all the possible places that can lead to that specific error code until I find where there is a problem…

VCNL4020 QT breakout board testing 🔧🔅🤝

This light and proximity sensor using the VCNL4020 https://www.digikey.com/en/products/detail/vishay-semiconductor-opto-division/VCNL4020-GS08/2813348 was designed a few months ago, but we were dragging our feet on writing the library code as its kind of a tedious process. Now, with our new BFF ChatGPT4, we can crank through a library with minimal typing. Of course, we check each function and #define as it is written - sometimes typos and misunderstandings come through.

@Moondog Seems good for me, a byte is a full turn. Maybe you can create a bunch of #define if you need easier values to work with.

Funny enough I am creating a small engine and I use 16b for angles, where 10b are the fractional part of one turn.

I run "in debug mode" and I see across hundreds of messages something "flying around" ( one of my "internal errors" ) saying "THAT FEATURE IS DISABLED" .. Disabled ?? WTF YOU MEAN DISABLED !! .. go to look around and find .. // comment this to disable ... // #define ENABLE_THAT_FEATURE 1 .. I disabled it to debug what I was debugging I COMPLETELY FORGOT ( and NOT written down in notes ) that I did .. .. *BANG* *BANG* *BANG* *BANG* ( head on the desk ) ..

😁 Well, when I saw things like:

#define TRY try {
#define CATCH } catch(...) {
#define CATCH_END }

nothing could surprise me anymore.
I'm just curious what other kind of language they wanted to simulate.

@jaybird110127 @datajake1999 Yeah. First, modify ph_drwt01.c. Search for #define HIGHEST_F0, and change that to something like 60001. 6000 is the frequency, I think 1 is the multiplier. Then modify #define LOWEST_F0, replacing 500 with something like 10. This appears twice, once for mainline and again for NWS builds. If you want it to affect the mainline builds, go to Line 2332 and replace the values there. Next, to allow the ap command to use the new range, go to ph_defi.c, and replace 50, 350, /* AP */ with the new range, something like 1, 6000.

Oh bloody hell, LOADS of these header files don't have #ifndef! Why have the #define line there if you're not going to check for it?!

@jeffcliff

How would you #define #religion?

Surface level definitions don’t quite do it for me. I wouldn’t say that religion is a belief in the supernatural, because #secular #Judaism is a thing. I wouldn’t say that religion is a belief in God, because #zen #Buddhism is a thing. I wouldn’t say that religion is a matter of obedience to inspired law, because #Satanism is a thing.

@regehr @DRMacIver Why #define comparison if it’s shorter than ‘comparison’? 🤔

@nytpu how about sth like this once in some header

#ifdef _WINDLL
#define DLLEXPORT __declspec(dllexport)
#else
#define DLLEXPORT
#endif

And then you just

DLLEXPORT
int
eventHandler(...)

@mbr #define FP_NAUGHTY_OPTIONS

@jonocarroll @brodriguesco oh. I don't

#define R_NO_REMAP

which means I get access to the shorter aliases i.e. without "Rf_" prefix.

@walkerb Reminded me of this:

FlexeLint for C/C++ (Unix) Vers. 9.00L, Copyright Gimpel Software 1985-2014
...
#define A 1l

Flexelint (I think it is no longer sold) is maybe the only closed source tool I would recommed:

Midnight thoughts on #success:

How do we #define success? For some it will be achieving a certain thing they’ve been working towards for a long time. For others it will be something as seemingly simple as getting out of bed.

Why is success such a hard thing to define? Because it is #unique to an #individual and to a #situation. There are no hard and fast rules definitively stating what success is and how to achieve it.

We don’t have any right to #judge others based on their success or lack thereof if we are using our own values as the metric against which someone else is being judged. We can admire their #achievements. We can encourage their #efforts. We can empathise with them in their #hardships. But we do not get to say what is or what isn’t a success because of how we regard it in our own lives.

Maybe success was getting to the end of this toot. Maybe it was finding 5 minutes to scroll on the socials. Maybe it was waking up in the first place.
