The Canvas' method create_line turns on at least 2 pixels. But I want

turn on many single pixels on a Canvas. How should I do this? Canvas has
no method create_pixel or create_point.

I just tried your script, and over here the line drawn with
def drawLine (self, pa, pb, color):
self.canvas.create_line (pa.x, pa.y, pb.x, pb.y, fill = color)
has a width of 1 pixel and does not include the end point. Therefore the
line drawn with
def drawPoint (self, p, color):
self.canvas.create_line (p.x, p.y, p.x, p.y, fill = color)
does not show up at all. You could try to specify the line width explicitly:
def drawPoint (self, p, color):
self.canvas.create_line (p.x, p.y, p.x+1, p.y, fill=color, width=1)
If that doesn't work (or there's too much overhead) use pillow to
prepare an
image and show that.
Another random idea: if you have a high resolution display your OS might
blow up everything. In that case there would be no fix on the application
level.

I'm stopping right here, so I don't risk tainting myself. How about you instead describe which macros you are missing, so someone can do a clean-room implementation of those macros. I did not copy my code from glibc's endian.h: I wrote my code yesterday, while on Windows Vista for 32 bits using joe on Cygwin and notepad. Now I'm using Ubuntu for x86-64. I'm also surprised that glibc's code is similar to mine: glibc's folks wrote: #ifdef __USE_BSD /* Conversion interfaces. */ # include bits/byteswap.h I wrote: #ifdef _BSD_SOURCE #include byteswap.h The man 3 page, from Linux and from the web, does not tell about __USE_BSD. The next line is equal, probably because the glibc's guy who wrote it also was using x86-32. If I would be using Ubuntu for x86-64 yesterday I would have written the opposite. #if __BYTE_ORDER == __LITTLE_ENDIAN If you want, to swap the order of my macros is very easy. Then glibc continues, interleaving be with le, and a pair of hto with another pair of toh: # define htobe16(x) __bswap_16 (x) # define htole16(x) (x) # define be16toh(x) __bswap_16 (x) # define le16toh(x) (x) It is very different from what I wrote. I interleaved the types: #define htobe16(x) bswap_16(x) #define htobe32(x) bswap_32(x) #define htobe64(x) bswap_64(x) To use bswap to implement hto and toh macros is the most intelligent approach. Fortunately, glibc's __bswap_16 differs from Cygwin's bswap_16. Also: glibc's style is different from mine: They use a space between the # and the define. After writing this message I'm proud that I'm as smart as the glibc's coder. I need the 64 bits macros only. I wrote the other macros for completeness.

Now I tried with Go-oo 3.2.0 build 9483 for x86_64.rpm on Ubuntu and the table was not preserved in the .doc . What should I write in the bug report? Could you report this bug for me?

Re: [users] scalc feature request
[]calc does not understand any Date pasted as DDMMAA even though it is able to represent =TODAY() using this format. As so often, Paste Special is your friend. Instead of using ordinary Paste: o Go to Edit | Paste Special... (or right-click | Paste Special... or Ctrl+Shift+V). o In the Paste Special dialogue, select Unformatted text. o In the Text Import dialogue, click in the relevant column to select it. o For Column type, select Date (DMY). I trust this helps. This would help if I would paste a column at once. But my specific case is that I need to paste date by date, that is cell by cell, as each date comes from a different html shown by some browser, which may be Firefox or IE. - To unsubscribe, e-mail: users-unsubscr...@openoffice.org For additional commands, e-mail: users-h...@openoffice.org

Re: bug in mbrtowc?
The bug is in O.P.'s code as s is not being passed to mbrtowc.
I'm on Ubuntu. I do not have Cygwin here.
I should consume some calories before trying to debug anything.

The sequence E2 94 84 should translate to U+2514. Instead, the second
and third calls to mbrtowc report encoding errors. It does work
correctly if the three bytes are passed to mbrtowc() in one go:
printf(%i\n, mbrtowc(wc, \xe2\x94\x84, 3, 0));
That's a bug in the newlib function __utf8_mbtowc. I'm really surprised
that this bug has never been reported before since it's in the code for
years, probably since it has been introduced in 2002.
I'll follow up on the newlib list.
Thanks for the report and especially thanks for the testcase,

From the Linux Programmer’s Manual (release 3.15 of the Linux man-pages):
If the n bytes starting at s do not contain a complete multibyte
character, mbrtowc() returns (size_t) -2.

Re: [c-prog] How OOP affect performance
--- Jos Timanta Tarigan asked: i want those vertices become objects in triangles. Interesting new concept :) here is my question: is calling vertices[i].move() will take less time than calling triangle[i].vertices[k].move() ? well i know it will but is it that significant? I never saw any conscious vertex that know how it should move ;) Every indirection takes time. How much time is that significant? How much time each indirection take? It depends on if the content of triangle[i] is cached or not. Are you paulista?
Re: [c-prog] How OOP affect performance
--- Jos Timanta Tarigan asked: im currently trying to convert a code from functional to OOP. but the program is performance sensitive kind of program. is it that significant to change from functional to OOP? how it will affect the programs performance(time and memory)? is it that much different from calling a function compared to a function from another object? Does functional here means procedural? The answer to this question is language dependent: Are you planning to do OOP using plain C? Or do you plan to use C++ or Java? Write a little performance tester and measure it yourself.

The behaviour on integer overflow is undefined. Hence,

And what the absence of this feature indicates?
Regarding my original problem:
I simplified the problem, compiled to assembly and modified the assembly to
get my desired result. It would be very simple to implement the right math,
that is, to consider the result of the multiplication of two integers as a long
long int, as shown below:

[c-prog] Re: integer promotions
For peternilsson42: I was not clear and you did not read message 68798. http://tech.groups.yahoo.com/group/c-prog/message/68798 To clarify: That code I compiled on two independent compilers. On both compilers: USHRT_MAX is 0x UINT_MAX is 0x ULLONG_MAX is 0x For integers with a 'rank' less than int, if the range of the integer type fits into the range of int, then that type will promote to int, if it is promoted. If the range won't fit into an int, it will be promoted to an unsigned int. It shows that you read the standard. Consider the test: (-1 (unsigned short) 1) Whilst intuitively it should always be true, there are many implementations where it is false! The unsigned short value 1 fits into an int and -1 is an int, so, according to the standard this test must be true. a = -1; I changed this line in message 68798 to: a = USHRT_MAX; Here's a table of what a will promote to, and the type of a * a, dependant on the maximum values of unsigned short, int and unsigned int: I'm sorry I was not sufficiently clear. Unsigned integers do not get sign-extended when promoted to wider unsigned integer types. Why? Because there is no sign to extend! This is exactly how I thought before I saw two independent compilers producing the binaries that result that result. First, you believe promotion works from the outside in. In other words, the type of the variable you're assigning to will influence the types and promotion of the expression on the right hand side. They won't. It works from the inside out. No. I used unsigned short int and unsigned long long int because the original calculation needs them, because the result of the original calculation may not fit inside an unsigned int. The original calculation is more complex than a multiplication of two integers. Secondly, you've probably been confused by 'hex' output No. I used hexadecimal representation because these extreme values are best represented in hexadecimal. I hope that you answer my question, that is explicit in my other message. My personal opinion is that the two independent compilers I used are buggy, but I want another opinion before reporting this bug to two independent developers.
[c-prog] integer promotions
If The integer promotions preserve value including sign.

unsigned short int a;
unsigned long long int b, c;
a = -1;

c = ((unsigned int)a*(unsigned int)a);

OK, I wrote a bad piece of code. Let me try to codify my problem again:
#include limits.h
#include stdio.h
int main (void) {
unsigned short int a;
unsigned long long int b, c;
a = USHRT_MAX;
b = (a*a);
c = ((unsigned int)a*(unsigned int)a);
printf (Why %llx != %llx ?\n, b, c);
return 0;
}
When I execute it I get:
Why fffe0001 != fffe0001 ?
b is wrong.
Is this a compiler's bug?

My first language was C64 Basic and my second language was Assembly. After I learned 80286 Assembly, object orientation was a punch in my face: I was taught not to mix code with data, just to learn otherwise afterwords. What is complicated in C++ is not the pointers subject, but pointers mixed with classes and namespaces. Java is sweet as it does not have explicit pointers. Plain C is sweet as it does not have classes nor namespaces. C++ is a hell.

The problem with the bad code referenced in this thread earlier is that that guy learned C++ from a book, skipped some pages, and has no working compiler to test his code before pressing the Send button.
