I'm currently going through the paper Extensibility for the Masses. Practical Extensibility with Object Algebras by Bruno C. d. S. Oliveira and William R. Cook (available many places on the internet - for example here: https://www.cs.utexas.edu/~wcook/Drafts/2012/ecoop2012.pdf).
On page 10, they write:

QUESTION
I have a repo called WebScraper with a single branch called main. I am the sole contributor to the repo but do so from multiple machines. There is NO gitignore file. The program scrapes web data and updates a fairly small csv (<2k lines). It runs daily on machine1.
Currently on machine1 CSV was edited this morning (1/25) and I can verify there's new data as the last lines are dated 1/25. Currently on web repo CSV was updated on 1/23 and I can verify this as the last lines are dated 1/23.
Inside the WebScraper dir I use git push and get a 'Everything up-to-date' message. A. Why does it fail to recognize that CSV has been recently updated?

Answered 2021-Feb-04 at 00:52The problem was I had not commited the changes prior to attempting to push them. Confusion arouse because I had been used to using GUI git interfaces (gitkraken) where they have a 'Stage' button that essentially is the same as commit. So Switching from GUI to CLI I wasn't aware of the need to commit prior to pushing. Many thanks for the help.
QUESTION
I'm trying to conjure a traversal to update multiple keys of an IntMap as a whole.
To dispell XY: I'm not simply trying to update them, I need the traversal to return to the caller for further composition. Or at least something composable with lenses.
I've tried many variations of the common combinators. I've tried dropping down to a functor-based definition, with a large range of experimentation shifting the forall
s' scopes around, with no more success. Building from the ground up again, here's where I'm at:
ANSWER
Answered 2021-Jan-15 at 15:09Traversal'
is a type synonym for a type containing forall
, which makes it a second class citizen in the type system: we can't instantiate a type variable with such a type.
In particular, here we are trying to do so with foldr :: (a -> b -> b) -> b -> [a] -> b
, we can't instantiate b = Traversal' _ _
, because Traversal'
contains a forall
.
One work around is to wrap Traversal'
in a newtype, ReifiedTraversal
. Wrap (using the Traversal
constructor) before passing at 1
to foldr
; inside foldr
, unwrap to use adjoin
, and rewrap; unwrap at the end.
QUESTION
I'm using HTML5 canvas in a project and occasionally need to draw drop shadows on SVGs within a canvas. I've noticed that, compared to Chrome, Safari does two things incorrectly when doing this:
- Safari draws a shadow on each individual shape within an SVG
- Safari crops off parts of the shadow that go beyond the SVG's bounds
These issues can be illustrated by the following code:
...ANSWER
Answered 2020-Dec-21 at 05:31That's a bug, you should report it to webkit's bug-tracker.
Though you can workaround it by first drawing the image on a second canvas just to rasterize that svg image and use that canvas as source for the shadowing:
QUESTION
I am wondering whether there is a way (maybe a standard method) to whether a given type has nested fields, or if it just a value 'by itself'.
To be clear what I mean by nested types, is types that contain other values (lists, arrays, objects, other more or less complex datastructures). By 'values by themselves' I just mean any type that does'nt contain other types, such as strings, int, boolean, char, long, double etc.
If I have to conjure up the signature for a specific method, the usecase would be something like this:
...ANSWER
Answered 2020-Dec-13 at 13:48You can use reflection to check if the type of a value is a primitive or if it does have fields. The method might look like this:
QUESTION
I am totally confused. There are many sources out there contradicting each other about the definitions of Dependency Injection and Inversion of Control. Here is the gist of my understanding without many additional detail, that in most cases made things more convoluted for me: Dependency Injection means that instead of my function conjuring the required dependencies, it is given the dependency as a parameter. Inversion of Control means that, for instance when you use a framework it is the framework that calls your userland code, and the control is inversed because in the 'default' case your code would be calling specific implementations in a library.
Now as I understand, somehow along the way, because my function that doesn't conjure up the dependencies anymore but gets it as an argument Inversion of Control magically happens when I use dependency injection like below.
So here is a silly example I wrote for myself to wrap my head around the idea:
getTime.js
...ANSWER
Answered 2020-Nov-08 at 12:26Check Martin Fowler's article on IoC and DI. https://martinfowler.com/articles/injection.html
IoC: Very generic word. This inversion can happen in many ways.
DI: Can be viewed as one branch of this generic word IoC.
So in your code when you specifically implements DI, one would say your code has this general idea of IoC in the flavor of DI. What really inversed is, the default way of looking for behavior (default way is writing it within the method, inversed way would be getting behavior injected from outside).

I am writing a Monte Carlo simulation to check how many times y was not immediately next to another y. I conjured up a vector of 40 x's and 10 y's placed at random position in the vector. My goal is to calculate the probabilities of not having any adjacent y's in the vector. Here is what I tried:

QUESTION
So response files are being used by default to specify the command line switches to the compiler and linker for some toolchains. This appears to apply only to makefiles, though. Arguably this is done to get around the 8192 character length limit for command lines on Windows, given my scenario with the NMake Makefiles
generator.
Apparently the settings are supposed to be governed by CMAKE__USE_RESPONSE_FILE_FOR_OBJECTS
which isn't exactly documented as far as I could find it. Anyway, various CMake scripts that come with the CMake (3.15.1) distribution contain either 0 or 1 for these settings (i.e. per language ). The only place where this appears to be read is
cmMakefileTargetGenerator::CheckUseResponseFileForObjects()
in cmMakefileTargetGenerator.cxx
(as of this writing).
Complementary settings exist in the form of CMAKE__USE_RESPONSE_FILE_FOR_INCLUDES
and CMAKE__USE_RESPONSE_FILE_FOR_LIBRARIES
.
Now while this technically works it really causes one undesired side effect for me. In the logs from automated builds I'd like to see what was happening (yep, I am also setting CMAKE_VERBOSE_MAKEFILE=ON
). Given the fact that these response files are being generated on the fly, the command lines I get to see from the log file look akin to:

Install conjure
You can use conjure like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
