I put it down to a limitation of the Aussie (and other) stock exchanges. The shares had dropped to $0.01, when their true value was negative, given the stapled obligations that they carried. Bolton should have been paid to take on the deb

Good, but overly long article. I have reached the similar conclusions in favor of functional tests over the last decade or so. Personally, I have worked seriously used DBC , TDD, and automated scenario testing, and hybrids in that order of

Kent Beck's book: Test-Driven Development Don't just read it: Work your way through it. You need to follow the recipe to develop the discipline/knack. Fairly quick and reasonably easy.

Side-track: The Romans used IIII for 4, not IV, etc. which was introduced by early printers (not dot-matrixes ;-) to save space, so the original system was more additive. Looked at in this light, you can see more easily how humanity progres

They do work; they just don't integrate with the built-in types: Why should they? Try instead: car(cons(1,2)) -> 1 cdr(cons(1,2)) -> 2 car(cons('a', cons(2, 3))) -> 'a'

Well right now you are using an application -- Hacker News -- that is written in pg's Arc language which runs as an interpreter on MzScheme which is part of PLT Scheme. Why don't more people use DrScheme, HTDP, etc.? This is a question abo

There have been a few attempts to methodologize a more "consultative approach" to Sales, notably SPIN Selling, Strategic Selling and Solution Selling. The last of these has been the most successful, and interestingly it was cooked up by a t

An app store gives somewhere for vendors to hang up their shingle (like a mall), and -- depending on the barriers to entry -- gives some assurance to "shoppers" looking for apps. We've just launched a new business app, bSelling - http://bc

For our first web-based product we (Austhink software) decided to go straight for integration with the web-based Salesforce CRM, and put it up on Salesfore.com's AppExchange marketplace. We've only just got it up there, but I thought that o

Yes, these idioms would work in Javascript too. I guess the point is that people are starting to discover that languages like Python and JS support these functional idioms quite nicely. Remember when all the books on JS pretended that it wa

We've looked at them. There service is pretty slick, and well-backed, but you need to pay a significant monthly fee (with 12 month lock-in) to get started, so you would want to have a good turn-over before going with them. They seem to be

Yes, in that case the inner function has access to the arguments of the outer function. But you can go deeper -- e.g. declaring an inner function inside code inside the out er function -- which also knows about the local variables in the o

Yes, "named let" is lovely, but perhaps less obvious for the non-cognoscenti. It also doesn't translate into Python, etc.

Learning Scheme helped my Python by teaching me some new (to me) idioms, besides the first-class function stuff. For example, it is natural in Scheme to declare a lot of local information, including local function definitions. These have t

"A big barrier to entry for Scheme is getting a nice environment set up" Dunno: DrScheme is very nice out-of-the-box.

Another possible collapse would be to say "I have two children, and the oldest [or youngest] is a girl". That would disambiguate GB & BG, by effectively stating I have G? [or ?G]. Then the odds would be 50%.

I too enjoy reading. I commute and read books on the train. I also read a bit before going to bed and otherwise opportunistically. I read multiple books at once, and this can be a problem. I have sworn not to buy any more books from Amaz

Most languages short-circuit ands and ors already, but adding additional short-circuiting demands macros: My practical example of this is my desire for a short-circuit "implies" operator to use in assertions (typically in post-conditions).
