I am not sure this has much value. The main benefit of live stream is
that everyone can ask questions online and those will be forwarded to
speakers. Isn't it better to simply wait for recorded high quality
videos otherwise?

P.S. devs from Europe did indeed have to stay awake through the night to
watch previous dconfs ;)

I hope so. The stream recording that was released on the fly was 
not good. I've remembered having watched the 5 first minutes of

Great article, some points I jotted down while reading:

* I would emphasize the fact that D has no C translation layer 
a little more, something like "because D uses the C memory 
model ..."
* Why do you use pre tags for numbered and bulleted lists? Use 
the native HTML tags instead

* I would wrap the code in text in  tags

dateparser hits 1.0

A little while ago, I wrote about a library I was writing to

http://forum.dlang.org/post/odowolmiykkdigfit...@forum.dlang.org 
Well, that library has reached 1.0!


https://github.com/JackStouffer/date-parser

I'm quite happy with it; it's reasonably fast for what its doing, 
it has very few GC allocations, it supports std.allocator's 
theAllocator, and it supports range inputs. On average, it's 
about 10x faster than the Python version when compiled with LDC.

I agree. I had been looking at the Discrete Math toolbox for 
Matlab to compare functionality and factorial seemed worth adding 
(as an aside, I saw an earlier thread about adding factorial to 
std.math and people were like nobody uses factorial and I wanted 
to punch my computer screen). Matlab's toolbox also has gcd, lcm, 
and some prime number functions.


I'm not entirely sold on the name of the binomial function. I'm 
concerned if it will be confusing if working with other 
dlangscience projects. Looking at dstats there are a bunch of 
functions with binomial in the name (rBinomial, binomialCDF, 
etc.). SciPy/SAS uses comb. Matlab uses nchoosek. R uses combn. 
I'm not a fan of combn.


Other potential overlapping functionality: logFactorial, 
logNcomb, Perm, perm, Comb, comb.

DConf 2016 announces programme, general registration opened thrugh April 22

[Andrei Alexandrescu via Digitalmars-d-announce]

The Fourth Annual Conference of the D Programming Language: DConf 2016

May 4 to May 6, 2016

Berlin, Germany

http://dconf.org/2016/

We have received many excellent submissions for DConf 2016, which made 
the selection process difficult. After long deliberations, the 
organizing committee is happy to announce we have a strong program 
featuring a mix of tutorials, advanced informational talks, experience 
reports, panels, and interviews that we hope would be of broad interest 
not within the D milieu, but also for prospective users and the broader 
software engineering community. Refer to http://dconf.org/2016/schedule 
for the full conference schedule.


The conference track contains 18 speakers, including the D language 
creator Walter Bright, language architect Andrei Alexandrescu, and D's 
build and release czar Martin Nowak. Leandro Lucarella will deliver a 
keynote covering the use of D at Sociomantic, a high-powered display 
advertising company built entirely on the D language. A combination of 
well-known and up-and-coming speakers completes the mix, check 
http://dconf.org/2016/speakers for details.


We encourage participation to DConf 2016 of all interested. Past edition 
attendees know that in addition to the excellent "official" technical 
content, the value multiplier of the conference is direct access to, and 
interaction with, colleagues, speakers, and luminaries of the industry. 
Attendance has doubled in size this edition, so gear up for three days 
of mind-blowing information, inspiration, and excitement.


Hope to see you there! Registration will be open through April 22, 2016 
but please hurry up as we might start pushing against venue limits soon.

Walter Bright, The D Language Foundation
Ali Çehreli, The D Language Foundation, Riverbed

Regarding ideas:
For each range, there should probably be a numeric function computing 
the length of that range. (e.g. here, binomial corresponds to 
combinations, there should be factorial corresponding to permutations etc.)


This table might provide some inspiration:
https://en.wikipedia.org/wiki/Twelvefold_way#Formulas

I'd suggest completing the set of functions and ranges such that they 
cover all cases in this table.
They can then be generalized. (E.g. instead of choosing a subset of a 
given size, one might want to choose multiple disjoint subsets of given 
sizes etc.)

Indirections in the return type also play into this. David Nadlinger
