Lambda the Ultimate

Another Logix? Another Ehud? I'm confused! We chose the name Logix because we liked the sound of it and it fits well with the name of our start-up (LiveLogix), but I've sinced realised that it's too widely used already. Expect a name change in the not too distant future. :(

Tom,

Great job on your language design. It is inspirational!

Also, why not allow replies to your blog?

Yeah - I just resent having to spend any of my time dealing with comment-spam. It's a shame though as I'd really like to encourage discussion - maybe I should re-think.

A friend just had to switch to a hosting company because we was getting so much spam that the anti-spam stuff was bringing the whole server to its knees. Anyone got any good tips for anti-comment-spam for WordPress? (I guess that's off topic, so: tom@livelogix.com - thanks)

Take one of your servers and load a SVG or SVG like library for the system of your choice (Java, PHP, Python, etc.). Create a simple script that will generate an image of a random dictionary word. Go from there...

but it's wrong. You would cut out blind people and other ones with vew problems in general.

Of course, if the blinds can't post, no one should. It's the best thing we've found so far, although i guess it'd be possible to do the same thing with generated sound files.

I read on the IKVM blog that in order to post one has to answer a simple programming question. That would be better, in my opinion.

in order to post one has to answer a simple programming question

Seriously - how is this answering done technically? I assume correctness of an answer is validated automatically. I see two basical ways to answer - by choosing from a list of options, and a free-form answer. The first is prone to bot attack by enumerating all possibilities, the second presents challenges to developers of questions... The right answer must be really unambigious and apparent to anyone with, eh, appropriate background. Which way is preferrable to err to - too obvious questions, risking spam, or too obscure, risking irritated innocents?

What is the result of this expression?
0x1f & 0xf1

Then type in 0x11 to validate your post.

What do you mean by "... the expression based approach of XSLT where a variable can be set conditionally (safely and contained) and not in the inside out way of C style statements..." exactly?

C style:
int age;
if (someOtherCondition > 5) {
age = 2;
} else {
age = 1;
}

XSLT:


2
1

The XSL example should read:

XSLT:
<xsl:variable name="age">
<xsl:choose>
<xsl:when test="$someOtherCondition &gt; 5">2</xsl:when>
<xsl:otherwise>1</xsl:otherwise>
</xsl:choose>
</xsl:variable>

you can do this in C:

int x = (someCondition > 5) ? 2 : 1;

but I agree that it's awkward in general...
