I can't say anything about Africa, though let me doubt wether all african chiefs would agree with you. Nor wether those which don't possibly would be right or not. Since it's Christmas today, one of the most interesting and likely true things i've ever read from a Christian is quoted in Peter Scholl-Latour's «Mord am großen Fluß. Ein Vierteljahrhundert afrikanische Unabhängigkeit» («Murder at the big river. A quarter of a century of African Independence»), somewhen in the 60s a (black) african Bishop stated something like «In the year 2700 the white people will have wasted all resources. Then the era of the black people will begin».

[9fans] MIPS LE fp register ordering in MOVD
Hello Fans,
It seems 0l/vl in little endian mode outputs wrong ordering of fp registers
in MOVD. For a double, which is stored in an even-odd pair of fp registers,
the least significant bits should be held in the even numbered register,
regardless of the endianess. When moving from/to memory, in LE mode the
first 4 bytes should go to even numbered registers, which is different from
BE mode.
A patch is submitted.

Never has there been a more versatile freely accessible environment than today, both, systems and languages.

Neither does gladhanding. it's easy to point out past mistakes. do you think these were obvious at the time they were made? Whether they were obvious is too subjective to determine. They were (often very loudly) recognized as mistakes. The problem, as usual, is that a well-funded mistake is far more likely to succeed than an impoverished masterpiece. Obvious? I'll never know. But people I respect decried lots of these decisions at the time they were made. Without getting into the chicken- and-egg problem of how I came to respect some of these people, in a lot of cases, stumbling across an angry netnews missive from a usenet address I trusted was catalytic in my process of coming to grips with some understanding of correct software design. The Unix Hater's Handbook is a collection of articles in this vein; there are systems eulogized therein which were displaced by the rise of unix, and whose passing makes me truly sad to have missed out on an era of computing with real diversity in system design. This is why harmful.cat-v.org is so important, and it's why I don't have any interest in suffering fools on internet mailing lists. If community is important in guiding software trends, it's important to nip encroaching macrocultures in the bud; otherwise we wind up with POSIX everywhere, and an entire generation of computer users who can't even conceive of a world without it. People like Blake can present me with bullshit about 'living in a cave' all day long -- but the surest way to prevent mistakes is to cause people to defend proposed change within an inch of their lives. That's the original point of a thesis defense, and the principal is no less valid on a mail list. Most people seem to take such challenges personally; this is just because they're not used to being challenged. It will pass. khm --- End Message ---
