   There's some confusion here. The Arthur OS ROMs, starting with 0.2 on EPROM, that's why Acorn wanted them back on the upgrade to 0.3 on ROM, were written in assembler, including `modules' like the filing systems, BASIC, and the Wimp that ga

   That was Chocks Away, a video that doesn't do it justice is http://www.youtube.com/watch?v=G0x5JbmU6HU. The dog fights were good and the missions had you shooting up balloons and moving trains too. You could link two machines with a seria

   A few errors (corrections sent) but worth a read. It was the first computer shipped containing an ARM, the ARM 2. Ignore the crummy looking screenshots of Arthur; the WIMP was usable in Arthur for single-tasked applications but a very-nice

   If you find the many slides with little text on each frustrating then `lynx -dump $url' gets you just the text to quickly skim.

   I get 500 Internal server error with some command-line HTTP fetchers, not wget(1). And http://www.rssboard.org/rss-validator/check.cgi?url=http%3A%... is unhappy.

   If anyone's not sure of the advantages of a text processor, like TeX or troff, over a WYSIWYG (or WYSI-all-YG, as Kernighan said) application, then http://www.schaffter.ca/mom/mom-02.html may help.

    Note, a plain dd will report progress on stderr if sent a SIGUSR1. That can sometimes be enough to avoid the overhead of pv(1) and sending huge amounts of data through another pipe.

    The shell gives this kind of behaviour already through pipes and commands like awk, sed, and dc. More natural translations of the calculations given might be $ seq 100 | awk '{s += $0} END {print s}' 5050 $ seq 20 | awk -v s=1

    What do you prefer about TBB over CSP-style channels, as in #golang?

    I'd be surprised if many users type it twice. I always copy from the first to the second and wonder why the form designer has bothered.

    I agree. Given count(star) is a common need you'd think there would be multiple count(star) results in the metadata for the table, each with a generation associated with it.

    I don't see it as a bug; the shell shouldn't get to see what was written to the terminal? BTW, it's the readline library that handles the Ctrl-L key binding to clear the screen rather than bash per se. $ bind -p | grep '\\C-l' "\C

    Sorry, I think it's a problem not worth solving; it's helpful to know this has occurred by the state the screen is in. If you want to solve it correctly then, since it's also common to have the cursor left bereft in the middle of a screen o

    I don't like it, but you can do <foo grep bar | ... if you really want L-to-R whilst avoiding the redundant cat and its overhead. That doesn't allow grep to do its speed-ups though, because it's still reading stdin, not a filen

    I'd echo that view, also with twenty years of (Unix) programming behind me. The start of the slippery slope seemed to be object-orientation; yes, it can be ideal in some areas, helps re-use if done well, but since the majority of source is

    The post you're replying to is wrong, it's not a typo; see my reply to it. For a background in the CSP languages have a browse of Russ Cox's http://swtch.com/~rsc/thread/ The reference [4] to Squeak is broken, it's now at http://research

    No, that is not a typo. A goroutine that blocks by making the thread it's currently running in block in the kernel is blocking that thread too; it must since the kernel needs some context for the on-going operation. What he's saying is that
