Slide 14:

PFFT (SSE) seems slow on LDC2: if you can extract a small 
test case
LLVM devs will appreciate a lot a bug report (they fixed many 
lacks of
optimizations submitted by me). If you have a link to the 
PFFT code

them maybe I can do that myself.

I don't know what PFFT stands for (can't google it either, 
funny results
shows up) but if it related to vectorization then maybe LDC 
has been
slower because it was built against LLVM 3.3 while LLVM 3.4 
brings more

vector optimizations.

Maybe all what has to be done, is rerunning benchmarks against 
LDC +

LLVM 3.4 ?


Slide 25:

Implicit invariants often hard to track down


Then maybe it's a good idea to add such invariants to the dmd 
front-end

code, even before its port to D.

My guess is Parallel Fast Fourier Transform.


It's Pretty Fast Fourier Transform. The code is at

https://github.com/jerro/pfft/tree/experimental

(I linked to the experimental branch because master branch is 
quite outdated)

I noticed that during the conference.  There were several talks where the  
mic was giving the AV guys trouble.  Each of the speakers was using a  
clip-on remote mic.  Of course, live, it wasn't as big a deal, as we could  
hear the person talking :)  But it would be more glaring for the recording.


I'm sure if there are any glitches that omit an important piece of the

With @UDAs, we have a lot of unrealized power for unit tests.

I have asked for ModuleInfo to contain an rtInfo member [1], like
TypeInfo does.  With that, and possibly splitting the unit tests into
individual functions (if not done already, I don't know), you have all
you need to completely re-design the unit testing framework.  It can
even be runtime selectable.


It would also be nice to not have to change the druntime to use RTInfo.  
Is that part of what you're suggesting?


No, currently RTInfo is for types only.  I want to have it work for  
modules as well (where unit tests typically live).


It would be nice to make it easily extensible.  I think that can be done  
by keying on certain members in the type/module.

Great talk!

Regarding the ci.lycus.org fleet, credit should definitely go to 
Adam Wilson (C# to D talk) and Kelly Wilson (same person who was 
present in the pie chart) too for providing many of the machines 
hooked up to the master node.


The fleet doesn't do a whole lot of work most of the time, so if 
you have a project that


1) has a sane build system;
2) you're willing to respond to build failures on;
3) and is 'significant' enough,

feel free to email me and I'll see what I can do.

(By 'significant' I mean "has enough impact to be useful for a 
reasonable amount of D programmers". This is of course pretty 
subjective, but we have to be a bit conservative about how many 
projects we add so that we don't end up having lots of stalled 
builds in the queue.)

What are the basic features you would require of a development

concept of a text editor, such as:

- The concept of a 'project' or some other collection of source
files which can be loaded/displayed in some fashion to make it easier
to find/select/edit individual files

- The ability to hook in 'tools' to key presses like "compile"
executing "dmd ..." or similar.



I've been using Programmer's Notepad 2 (for *all* my development for
the past few years), which is *mostly* a syntax highlighting
editor, but also has a concept of projects, configurable tools, and
"click an error to jump to it's line in the source". And I've never had
it crash or get wonky, or slowdown, or stall, or use a lot of resources,
ever.


Oh, yes, the ability to capture the compiler output and do a bit of a
