Sophie Wilson, formerly Roger Wilson, designed the ARM's instruction set. http://en.wikipedia.org/wiki/Sophie_Wilson Also wrote the BBC BASIC ROMs used on Acorn computers in 6502, and later BBC BASIC V (five) in ARM. (ARM originally sto

It's a shame the CSP style of tackling parallel programming hasn't caught on more. The Bell Labs guys know how to do this, see their languages Alef and Limbo. Channels, message passing, etc. Also, a UK university used to have some nice s

I'll be more impressed when Gmail supports RFC'd headers like Resent-From and Resent-To. They were in RFC 822 (1982) and are still in RFC 2822 (2001). How can an email client be written that doesn't handle these basic headers? It suggest

Readability is improved by not having the else clause. It makes it clear that the return in the then-block is there and the code won't continue after the end-if.

It's interesting so far, but, my, isn't Jessica a pacer. I feel slightly nauseous, as if I'm watching a rolling horizon at sea. Thought I'd hit pause to put out the stabilisers and post. Hope you have hard floors at home, Jessica, and no

Pedantically, Uncle Sid, not uncle Sid? Sid is my uncle, but to me, he's Uncle Sid. Or is that a Britishism?

Minor point: Consider the international audience and drop the "anyways"; it's slack.

Grow some self-controlling balls. Alternatively, only read articles that look interesting in a once-every-24-hour RSS grab and don't otherwise visit the site. Works for me.

The right way to do concurrency for most applications is the CSP style. Look at Bell Labs' Limbo or Alef which have channels. And Stackless has picked up on this in some ways.

`my' is also an alternative, can make the code look less cluttered.

You could trace the problems back beyond fractional reserve banking and say that axing the Gold Standard and having a fiat currency was the first con. Certainly, if credit is too cheap, asset prices will rise as borrowers outbid one another

Agreed. The pseudo-code had it in a more readable style. If it must be compressed onto one line then a = 0; b = (0, 0); c = float('infinity') is preferable if a, b, and c are logically unrelated compared to a, b, c = 0, (0,

You can also drop the selected text just to the right of the rightmost tab, left of the "scroll tabs right" arrow. When you're over the right spot, a down-pointing arrow appears indicating that a new tab will be created there. This actual

The 121 seconds of my time would have been better spent showing me it in action instead of trying to instill that there's only one M in scrumy.com. I know that now, but I don't need to know it since I'm not planning on spending more time i

You're assuming a limit on password length won't apply. In that case, I may as well print it in binary and just have 0 and 1 ASCII characters in my password.

Some of us are old enough to have used ed(1) out of necessity. :-) These days, `sed -i' is also useful for quick one-liners.

You used `md5' in your pipeline, I assumed you meant md5sum(1) as I'm not aware of an md5 command. md5sum gives a 32 character string that's the 128-bit MD5 digest in hex. Therefore it uses only characters 0-9a-f making the password weake

head may read an awful lot from /dev/urandom before it exits. ;-) And md5sum would limit my password to 0-9a-f whereas with tr(1) I get to choose the character set.

Have a closer look at the photo. There's rows of holes for connectors along the top and bottom of the board. I see one set is labelled JTAG. It looks like the tracks and holes are there for soldering on other I/O connectors if you wish.

Another unwelcome change is that the XML you get from, e.g. http://del.icio.us/api/tags/get now comes with a trailing comment containing the date and time. This means periodically downloading your data to store off-del.icio.us results in
