How does something like:
from email.header import decode_header
def test(s):
print(s)
s2 = decode_header(s)
print(s2[0][0])
print(s2[1][0].strip())
test('=?iso-8859-9?b?T/B1eg==?= ')
test('=?utf-8?Q?=EB=AF=B8?= ')
test('=?GBK?B?0Pu66A==?= ')
test('=?UTF-8?B?zp3Or866zr/PgiDOks6tz4HOs86/z4I=?=
')
work?

WSJ want their articles to be findable from Google. So they open up for Google indexing them. If they require any type of registration to see an article, then Google will remove the link.

That is still only 6 lines of C code and not 50 as you claimed:
double il = 0.0;
for (int i=0; i
Not that it matters, but the above requires C99 (or C++).

[snip] I don't see the distinction. Just dissasemble it and find out. There's a 1:1 relationship between machine code and assembler. Unless its a macro-assembler, of course! Each op is a routine in microcode. That is machine code. Those op routines use machine cycles. Not necessarily. An awful lot of CPU cycles were used before microcode was introduced. Mainframes and minis designed before about 1970 didn't use or need it and I'm pretty sure that there was no microcode in the original 8/16 bit microprocessors either (6800, 6809, 6502, 8080, 8086, Z80 and friends). The number of clock cycles per instruction isn't a guide either. The only processors I know that got close to 1 cycle/instruction were all RISC, all used large lumps of microcode and were heavily pipelined. By contrast the ICL 1900 series (3rd generation mainframe, no microcode, no pipeline, 24 bit word) averaged 3 clock cycles per instruction. Motorola 6800 and 6809 (no microcode or pipelines either, 1 byte fetch) average 4 - 5 cycles/instruction. One problem with this discussion is that the term "microcode" isn't really well-defined. There's the vertical kind, the horizontal kind, with and without internal control-flow constructs, and then there are various levels of visibility to the user -- see e.g. the pdp-8 manual, where "microcoding" is used to mean piling the bits for a bunch of instructions together in the same memory location, which works fine as long as the instructions in question don't use conflicting sets of bits. I thought microcode was relative well defined as being the software used to implement instructions that were not fully implemented in hardware. http://en.wikipedia.org/wiki/Microcode does not make me think otherwise.

IIRC the CYBER had a subroutine instruction that stored the return address in the location that the instruction referenced and then jumped to the address following that location. To implement a recursive procedure you started the code of the procedure with saving the return address to a stack. It was of course doable. Else Pascal would have been hard to implement.

Did it occur to you that there are nothing about Java in the above ? Looking at the original post, it doesn't appear to be about any specific language. Indeed. That suggests it's probably off-topic in most, if not all, of the newsgroups to which it was posted, inasmuch as they exist for topics specific to a given programming language. Perhaps - comp.programming might of been a better place, but not all people who follow groups for specific languages follow a general group like that - but let me ask you something. What is it you really have against discussing topics with people of neighboring groups? Keep in mind you don't have to read anything you do not want to read. [1] I very much doubt that the original thread is relevant for the Java group. But the subthread Lew commente don was about Perl and Unix. That is clearly off topic. I agree with and understand what you are saying in general, but still, isn't it possible that were are people in the java group (and others) who might of been following the thread, only to discover (probably not right away) that someone decided to remove the group they were reading the thread from? I know I would not like that, even if it wasn't on topic at the branch. Personally, I find it very annoying to have to switch news groups in order to resume a thread and weed my way down the thread to where it left off before it was cut off from the previous group. I am relative tolerant towards threads that are a bit off topic, if the S/N ratio overall is good. But I accept and respect that other people has a more strict attitude against off topic posts. And I am very little tolerant towards people that think they can attack those that want only on topic posts. One thing is to ask for a bit of slack regarding the rules something else is attacking those that want the rules kept. Arne -- http://mail.python.org/mailman/listinfo/python-list

Usually it is not a good thing, because it makes the code much more difficult to read. But sometimes it is handy. I think C# got it right. It allows it but require an explicit marking of it in both formal argument list and actual argument list. >> Java, Python, and Ruby, and we pass in a reference to object (not C+ >> +'s meaning of alias reference) > > In what way does the C++ reference differ from those in Java, Python, > and Ruby in this situation?
