Currently register looks like:

   private static <T> void register(Map<T, T> substitutions, T annotated, T original, T target) {
        if (annotated != null) {
            guarantee(!substitutions.containsKey(annotated) || substitutions.get(annotated) == original || substitutions.get(annotated) == target, "Already registered: %s", annotated);
            substitutions.put(annotated,

In recent versions (can't say from exactly when), there seems to be an off-by-one error in dcc.DatePickerRange. I set max_date_allowed = datetime.today().date(), but in the calendar, yesterday is the maximum date allowed. I see it in my apps, and it is also present in the first example on the DatePickerRange documentation page.

Description of the problem

As of the changes in #3160 , builds of the CRAN version of the R package with gcc now raise "unknown pragma" warnings.

CRAN does not allow the use of -Wunknown-pragmas to suppress such warnings, so we remove them with sed when building the R package.

The "bug" here is that LightGBM's CI did not catch this. That should also be fixed.

How to fix thi

Most names of generated_holidays contain spaces, and so fail to plot when passed to plot_forecast_component(). The tidyeval approach is to forego using aes_() or aes_string() and instead use quasiquotation in aes.

This is the same issue as documented [here](https://stackoverflow.com/questions/51658629/ggplot-aes-string-

Problem:
catboost version: 0.23.2

Impossible to use custom metric (С++).

I'm happy to announce that I'll be writing the second edition of Data Science at the Command Line (O'Reilly, 2014). This issue explains why I think a second edition is needed, lists what changes I plan to make, and presents a tentative outline. Finally, I have a few words about the process and giving feedback.

Why a second edition?

While the command line as a technology and as a way of w

I'm sorry if I missed this functionality, but CLI version hasn't it for sure (I saw the related code only in generate_code_examples.py). I guess it will be very useful to eliminate copy-paste phase, especially for large models.

Of course, piping is a solution, but not for development in Jupyter Notebook, for example.
