i for reals hosed this up on a work assignment a couple of weeks ago, writing a simple udp protocol in C++, no big deal right? well when I (thought I was) done we were all wondering why it didn't work, turns out I forgot to use htons to convert the port number before some call, so port 8800 became something like 24610
Imean, why on earth does it require the bytes in the port value to be manually swapped before passing it to the function to open a socket though

I'm currently kicking myself that I left the data dumping format for my current project in my mcu's default byte order (which is little-endian, contrary to what I had assumed. rear end/you/me etc), making the output difficult to eyeball which was the whole point of having a data dump. Blurg.

I vote we return to word-addressed cpu architectures so as to avoid the whole endianness bs entirely
I mean thats basically how cpus already work internally anyway, its words all the way down to the memory bus interface bytes only come into play when the cpu masks out irrelevant parts of whatever word its working with, all of which might just as well be done in software, like they used to

To be fair, I think plangs are amazing when it comes to string handling, and I loving hate how C handles strings. Hell, most modern ~*~*Desktop*~*~ processors have string instructions built right in.

gently caress, make it an option in gcc to go string + string = newstring.

Well, sort of. The string instructions, like many of the really CISCy parts of x86 have not been implemented for speed rather than mininal transistor count since the 486 days and are indeed often slower than doing simpler instructions in a loop (although if you're doing demos or whatever some of the looping instructions are still worthwhile i think in order to get your footprint down).

I also do embedded Linux, and string manipulation is great if you are parsing information from other programs.

That does make sense, I just want easy string manipulation like other plangs.

i know about the standard twos complement signed integer representations (the de facto standard due to ease of implementation, but not the only one, there's also some endianness bullshit)

i know about floats and doubles and ieee754. i also know that integers from -(2^52)+1 to (2^52)-1 can be stored in a double without any loss in precision because thats how doubles work.

if on most days you work with 32-bit integers you can work with doubles without any care. also most js engines optimize operations like this to integers so it doesnt matter anyway

turns out multiplying two 32 bit integers needs 64 bits of precision

also switchable endian mcus are the greatest!

like, what, you want to overload the + operator so you don't have to type strcat? or do you want it to call malloc for you too, so now you suddenly have memory you have to free that you didn't explicitly allocate? how do you handle strings that aren't null terminated?

Hey man, I'm not thinking to hard about this OK? I have been writing a wireless API that outputs to a custom built web-server and in the process I have done more string manipulation than I care to ever do again. I'm not bad at it by any means and completely understand it. I am just getting lazy OK? :smith:

quote:

6 Ere now, looking down from my window through the lattice, 7 I have watched the thoughtless crowd, and seen some gallant, more insensate than the rest, 8 crossing the street at the corner where such a woman dwells. Now his steps are taking him near that abode of hers; 9 the day wanes, and the light fades; night spreads her pall of darkness. 10 Who comes to meet him? A woman in right harlot�s guise, that goes out, ready of speech, to hunt men�s lives. 11 No rest for her, stay at home she cannot; 12 ever in street and market-place she lies in ambush, at some corner of the ways. 13 She draws him to herself and kisses him, flattering him with her bold speech: 14 Only to-day I have paid a vow that I owed for my preservation, and here are my victims freshly killed; 15 so I came out to find thee, longing for the sight of thee, and here thou art! 16 Soft, soft I have made my bed, spread it with embroidered tapestries of Egyptian woof; 17 freshly scented is that bower of mine with myrrh, and aloes, and cinnamon. 18 Come, let us lose ourselves in dalliance, all the night through let us enjoy the long-desired embrace. 19 My home stands masterless, my husband far away, 20 and his purse with him; no fear of his returning till the moon is full.

21 Alas, the ready speech that beguiles him, the seducing lips that lead him captive away! 22 He follows without more ado, unwitting as the ox that goes to the shambles, or a frisking lamb;[1] nor knows what fetters await him, 23 till the shaft is already deep in his bosom. So joyfully flies bird into snare, heedless of its life�s peril. 24 Heed me well, my son; let not this warning be given in vain; 25 do not let her steal thy heart away, do not be enticed by her beckoning. 26 Many the wounds such a woman has dealt; a brave retinue she has of men murdered; 27 truly her house is the grave�s ante-chamber, opens the door into the secret closet of death.

they made some stupid decisions though. for example:

C# code:

byte x = 1, y = 2, z;
z = x + y;

is an error, because the type of (byte) + (byte) is an int for some reason. so you have to cast it back to a byte. i think the same is true of int16s. this results in a lot of bullshit casts all over the place.

javascript has some bad parts (no integers, no proper arrays) but its not deserving of the amount of hate it gets. closures are awesome and javascript does them really well. i also like the object literal notation. and it can be kinda fun to write. heres a game i made

again if you're willing to not bother supporting old IE (<10) you have the option of using typed arrays. https://developer.mozilla.org/en-US/docs/JavaScript/Typed_arrays

Int8Array, Int16Array, Int32Array
Uint8Array, Uint16Array, Uint32Array, Uint8ClampedArray
