Another type of functionality that would be useful:
https://www.mathworks.com/help/matlab/ref/fzero.html

This can be done with a non-linear least squares, but I don't 
think that's the most efficient method.


D's findRoot probably is the world's most efficient and robust 
implementation. For single initial point fzero we can be 
implemented as IEEE set binary search of second initial point x1 
such that sign(f(x0)) != sign(f(x1)) plus D's findRoot.

As promised in my tweet of June 30 (and to the handful of 
people who emailed me), the cloud of mystery surrounding the 
use of the money raised for code-d and its supporting tools has 
now been (partially) lifted!


In this post, I lay out the details of how the first $1000 will 
be paid out to project maintainer Jan Jurzitza, a.k.a 
Webfreak001, and explain what we hope to achieve with this 
ecosystem fundraising initiative going forward.


This time around, it all came together in the background of 
prepping for DConf with little forethought beyond activating an 
Open Collective goal and then working with Jan to determine the 
details. Lessons were learned. Later this year, you'll see the 
result when we announce the next of what we hope to be an 
ongoing series of funding targets.

Nice explication of the plan, really needed. Why github never 
rolled out such a bounty program for OSS and other public 
projects has to be one of the head-scratching moves of all time, 
no wonder they were about to run out of money before they sold.


A good way to decide on future projects would be to let 
prospective donors stake money on various proposals, to see how 
much backing they might receive, sort of like how kickstarter and 
other crowdfunding sites work.

"submit an application" -> apply (confusing otherwise)

Maybe sum up and make clear that each student can earn between 
$3000-4000, instead of capped at $1k.


Why limit it to students? If the goal is to have a youth 
injection, just use an age limit- say 18-25- I see no reason 
for the stupid college bias.


Hi Joakim.

Thanks for suggestions.


Sure, thanks for funding this worthwhile initiative.

I don't know what legal aspects there are relating to targeting 
age in different countries.  We are definitely targeting people 
earlier in their careers.  I agree with you that talent isn't 
only found amongst students, and I've in the past hired someone 
that didn't even finish high school and has gone on to do good 
work for the D community.  So as far as Symmetry goes we are 
very open to unusual talent.  A degree is just one piece of 
interesting information.


Yes, but the current requirements exclude, for example, recent 
college grads who may not be employed yet and might do much 
better work than a harried college student. I don't know the 
legal risks in detail, but I can't imagine the risk/reward to 
opening it up would favor the current limitation.

Very cool. It's awesome to be able to directly #include C++ 
headers.


C++ headers with all basic features are not yet there.  Atila 
thought it might be a couple of months work full-time to be able 
to do


 #include 

It's not out of the question to make that investment, but we need 
to hire a few more programmers locally first.

Great! Wish I was a student still : D.


Me too !  Kidding aside, if you would be interested in a job

There's quite a lot of work involved in organising something like 
this, and I'm very grateful to the D Foundation for doing such an 
excellent job.


We can refine this for next year, but I wanted to make a start.
