http://community.wolfram.com/groups/-/m/t/1325863
I recently set up a package server in GitHub and need some people to submit packages to see how this can work. The server is here: https://paclets.github.io/PacletServer/
[ ![pm pick](https://i.stack.imgur.com/JIqln.png) ](https://paclets.github.io/PacletServer/)
It can handle one-line installation, gives a log of who changed which paclets, and can deal with submissions from anyone.
I'm looking for people to test this system out. Szabolcs kindly submitted a few of his and gave me feedback, but obviously he really knows what he's doing and so the system didn't bump into any real issues. That is likely not the case for most of us (not for me at least).
I'd like people to submit their packages via the instructions [on the GitHub repo](https://github.com/paclets/PacletServer#contributing-a-paclet) so I can see where things can be improved.b3m2a1 2018-04-24T06:36:25ZGenerate a rectangular Code using the CodingTheory Package?
http://community.wolfram.com/groups/-/m/t/1324698
Hello, I'm new in the community.
Does anyone know how to generate a rectangular Code of length between 80 and 100 and then get the parameters of that Code?
I only know that I have yo use the CodingTheory Package.
Thanks.Juan Marcos Díaz2018-04-22T20:41:49ZInstall MathToolBox package?
http://community.wolfram.com/groups/-/m/t/1324339
The MathToolBox package, listed at http://packagedata.net and available at https://yadi.sk/d/oC5lXLWa3PVEhi, contains a single `.m` file, namely, `MathToolBox.m`. But when I look at the contents of that file, I find a bunch of individual`BeginPackage` expressions there, none seeming to be named `MathToolBox`.
How should this be installed so that one can readily load it?
(I do wish that authors who publicly post packages would always include installation instructions! Today, the standard way seems to be to have a directory `ThePackageName` that contains the actual package `ThePackageName.m`, whose code begins with ``BeginPackage["ThePackageName`"]``; and a subdirectory `Kernel` that contains a simple `init.m` file of the form ``Needs[["ThePackageName`ThePackageName`"]``, or perhaps the same thing but with `Get` instead of `Needs`.)Murray Eisenberg2018-04-20T20:23:55ZAdd the ["BestFitParameters"] property to a function from a package?
http://community.wolfram.com/groups/-/m/t/1323091
I am building a MonteCarlo simulation to compare the performance of Least Squares and Quantile Regressions. To automate the notebook, I need to be able to extract the parameters from the regressions. For the Least Squares method, I can run a *LinearModelFit* and use the property *["BestFitParameters"]*.
For Quantile Regressions, I run the *QuantileRegressionFit* from the package below (written by Anton Antonov - Quantile regression Mathematica package, source code at GitHub, [MathematicaForPrediction][1], package QuantileRegression.m, (2013)).
However, the function doesn't come with the same property, *["BestFitParameters"]*, so I don't know how to extract the parameters.
Can anyone help me with extracting the optimal parameters for the *QuantileRegressionFit* function?

http://community.wolfram.com/groups/-/m/t/1321057
This is a cautionary tale for those who choose Mathematica as the main tool for their work.
It is now clear to me that Wolfram has simply abandoned the [Graphs and Networks](http://reference.wolfram.com/language/guide/GraphsAndNetworks.html) functionality area and I am left high and dry. I have no recourse because Mathematica is closed source so there is only so much a user can do to fix or work around problems. Reporting bugs in this particular area has now clearly proven to be useless. Most simply do not get fixed, no matter how serious they are, or how great a hindrance they are to practical use. No new functionality has been added since version 10.0. My colleagues who use other tools (mostly Python and R packages) are more productive at this point, but I have a handicap with those systems because I made the mistake of investing most of my time into Mathematica, and stayed optimistic about it even in the face of the most obvious warning signs.
I am writing this post because those people who have not heavily invested in Mathematica, and in particular this functionality area of Mathematica, are not in a position to see this and may fall in the same trap I did. What if the same thing happens to the functionality area that is critical to *your* work?
Wolfram Research, of course, will not tell you that they gave up on `Graph`. Thus, after my experience, I think I owe it to the community to warn you about the situation.
----
Some might ask me what specifically is wrong. I have made many posts on this forum about `Graph`-bugs (you only have to search), and I reported many more to WRI. There is always a last straw—it would be pointless to show it. Those who know me will know that I am not writing this admittedly emotional post out of ill will towards WRI. I have betted on Mathematica more than most, and have been advocating for it throughout the years. I even have a network analysis package with ~250 functions. If I am forced to abandon Mathematica for this type of work, then the countless hours that went into this package will all have been in vain.
I admit that I am writing this public post partly out of desperation to try to get WRI to either fix the many serious `Graph`-problems, or otherwise publicly state that `Graph` is now abandoned so those of us who have been using it can stop wasting our time.Szabolcs Horvát2018-04-16T09:54:42Z
