I found this talk particularly interesting on a personal level. I 
worked with OLAP data for a year and it was all Java and 
JavaScript programming. I had been thinking about how you could 
improve on either with compile time features in D for massive 
improvements in speed. This is a market where customers care 
about speed, and beating your competitors can be worth millions. 
It's nice to see that someone has done some work in this area.

Heh. Check my post. Wish I had more experience that days ;)

Very nice talk! And quite an interesting piece of software you built there.
Thanks also for sharing the slides: it's fun to see that much
templated code in a presentation and it's nice to be able to pore over
some of it.

On the 'issues with D' slide, you cite 'Can't get member names from Tuples'.
Do you mean:

alias Entry = Tuple!(int, "index", string, "value");

=> getting ["index", "value"]

?

Yeah, that's what he meant.  Using MemberNames and tupleof(..).stringof 
give the actual field names which are procedurally generated.  The user-
supplied names are simply aliases to the generated fields.

This talk was awesome - thank you Jonathan! I didn't see it when 
streaming, so thanks for sharing. It's touchy mainly because it 
brought some memories back. I was running my own business (soon 
after finishing uni) and got into the data processing world after 
taking some inquiry.

Funny thing is it's all started when I was asked to create some 
*excel* stuff dealing with a gov data. I quickly moved to PHP 
wagon as it was mainstream that days. After I figure out I was 
betrayed by PHP euphoria I started to look for the perfect 
programming language. Then I saw D and I knew it was it. 
Unfortunately  my business didn't pay my bills already at that 
time, so I had to say sorry to C++ and live with it (full time 
job).

Now I make a living from C++ (quasi embedded), but D is my number 
one as the language of choice, so I plan to reopen my business 
again this time with D from the beginning. Time will tell :)

BTW. As as GUI dependant guy I still consider debugging as 
Achilles heel of D (as referred in the talk to some extent, i.e. 
stack traces, mangling etc).

My programming language path (only languages included with more 
than 10k LOC written as I dealt with Python, Java, Matlab, Visual 
Basic and other "crap")
1. Pascal (high school)
2. C++ (high school and uni)
3. PHP (late years of uni)
4. PHP (own business)
5. PHP + D (closing my business)
5. C++ (a regular job)
6. D (the future ;))

I seems that both of you are quite confused between clang and
LLVM.

One thing that positively surprised me is how deep into advanced 
D features some snippets go. Back when I was doing C++ usage of 
any overly advanced template tricks was highly discouraged with a 
reasoning that it will make application non-maintainable by 
anyone else but original author and it will eventually crush 
under technical debt. The fact that D makes it possible to 
actually use the language power in team with varying proficiency 
level and still move forward successfully - that is a great 
indicator of design success alone.

Yes, and that is a very common theme amongst all the talks at dconf.
