QUESTION
Motivating background info: I maintain a C++ library, and I spent way too much time this weekend tracking down a mysterious memory-corruption problem in an application that links to this library. The problem eventually turned out to be caused by the fact that the C++ library was built with a particular -DBLAH_BLAH compiler-flag, while the application's code was being compiled without that -DBLAH_BLAH flag, and that led to the library-code and the application-code interpreting the classes declared in the library's header-files differently in terms of data-layout. That is: sizeof(ThisOneParticularClass) would return a different value when invoked from a .cpp file in the application than it would when invoked from a .cpp file in the library.
So far, so unfortunate -- I have addressed the immediate problem by making sure that the library and application are both built using the same preprocessor-flags, and I also modified the library so that the presence or absence of the -DBLAH_BLAH flag won't affect the sizeof() its exported classes... but I feel like that wasn't really enough to address the more general problem of a library being compiled with different preprocessor-flags than the application that uses that library. Ideally I'd like to find a mechanism that would catch that sort of problem at compile-time, rather than allowing it to silently invoke undefined behavior at runtime. Is there a good technique for doing that? (All I can think of is to auto-generate a header file with #ifdef/#ifndef tests for the application code to #include, that would deliberately #error out if the necessary #defines aren't set, or perhaps would automatically-set the appropriate #defines right there... but that feels a lot like reinventing automake and similar, which seems like potentially opening a big can of worms)
ANSWER
Answered 2022-Apr-04 at 16:07One way of implementing such a check is to provide definition/declaration pairs for global variables that change, according to whether or not particular macros/tokens are defined. Doing so will cause a linker error if a declaration in a header, when included by a client source, does not match that used when building the library.
As a brief illustration, consider the following section, to be added to the "MyLibrary.h" header file (included both when building the library and when using it):
QUESTION
I am trying to connect my Android 11 device with android studio over adb wifi but it is not working.
I updated to latest stable bumblebee and updated my SDK I tried turning off firewall on my pc but it is same result.
When I use QR code method my android phone just shows "pairing device" and nothing happens If I try the code method, android studio just shows "searching for devices" but nothing happens
and, yes, I enabled wireless debugging on my phone and I am connected to the same wifi network.
I don't know if the problem is with my computer or phone. I do not have any other Android11+ phone to try with
...ANSWER
Answered 2022-Jan-30 at 21:44I was having the same problem as you. Neither pairing by QR nor by pairing code worked.
So I tried connecting by typing adb connect [phone_ip]:[port] in the terminal and that worked flawlessly. Didn't even need to plug the phone to the computer with USB. Your phone will tell you the IP and port right above the "pair with QR code" option inside the Wifi-debugging setting. Just connect to that address.
QUESTION
There are so many ways to define colour scales within ggplot2. After just loading ggplot2 I count 22 functions beginging with scale_color_* (or scale_colour_*) and same number beginging with scale_fill_*. Is it possible to briefly name the purpose of the functions below? Particularly I struggle with the differences of some of the functions and when to use them.
- scale_*_binned()
- scale_*_brewer()
- scale_*_continuous()
- scale_*_date()
- scale_*_datetime()
- scale_*_discrete()
- scale_*_distiller()
- scale_*_fermenter()
- scale_*_gradient()
- scale_*_gradient2()
- scale_*_gradientn()
- scale_*_grey()
- scale_*_hue()
- scale_*_identity()
- scale_*_manual()
- scale_*_ordinal()
- scale_*_steps()
- scale_*_steps2()
- scale_*_stepsn()
- scale_*_viridis_b()
- scale_*_viridis_c()
- scale_*_viridis_d()
What I tried
I've tried to make some research on the web but the more I read the more I get onfused. To drop some random example: "The default scale for continuous fill scales is scale_fill_continuous() which in turn defaults to scale_fill_gradient()". I do not get what the difference of both functions is. Again, this is just an example. Same is true for scale_color_binned() and scale_color_discrete() where I can not name the difference. And in case of scale_color_date() and scale_color_datetime() the destription says "scale_*_gradient creates a two colour gradient (low-high), scale_*_gradient2 creates a diverging colour gradient (low-mid-high), scale_*_gradientn creates a n-colour gradient." which is nice to know but how is this related to scale_color_date() and scale_color_datetime()? Looking for those functions on the web does not give me very informative sources either. Reading on this topic gets also chaotic because there are tons of color palettes in different packages which are sequential/ diverging/ qualitative plus one can set same color in different ways, i.e. by color name, rgb, number, hex code or palette name. In part this is not directly related to the question about the 2*22 functions but in some cases it is because providing a "wrong" palette results in an error (e.g. the error"Continuous value supplied to discrete scale).
Why I ask this
I need to do many plots for my work and I am supposed to provide some function that returns all kind of plots. The plots are supposed to have similiar layout so that they fit well together. One aspect I need to consider here is that the colour scales of the plots go well together. See here for example, where so many different kind of plots have same colour scale. I was hoping I could use some general function which provides a colour palette to any data, regardless of whether the data is continuous or categorical, whether it is a fill or col easthetic. But since this is not how colour scales are defined in ggplot2 I need to understand what all those functions are good for.
ANSWER
Answered 2022-Feb-01 at 18:14This is a good question... and I would have hoped there would be a practical guide somewhere. One could question if SO would be a good place to ask this question, but regardless, here's my attempt to summarize the various scale_color_*() and scale_fill_*() functions built into ggplot2. Here, we'll describe the range of functions using scale_color_*(); however, the same general rules will apply for scale_fill_*() functions.
There are 22 functions in all, but happily we can group them intelligently based on practical usage scenarios. There are three key criteria that can be used to define practically how to use each of the scale_color_*() functions:
Nature of the mapping data. Is the data mapped to the color aesthetic discrete or continuous? CONTINUOUS data is something that can be explained via real numbers: time, temperature, lengths - these are all continuous because even if your observations are
1and2, there can exist something that would have a theoretical value of1.5. DISCRETE data is just the opposite: you cannot express this data via real numbers. Take, for example, if your observations were:"Model A"and"Model B". There is no obvious way to express something in-between those two. As such, you can only represent these as single colors or numbers.The Colorspace. The color palette used to draw onto the plot. By default,
ggplot2uses (I believe) a color palette based on evenly-spaced hue values. There are other functions built into the library that use either Brewer palettes or Viridis colorspaces.The level of Specification. Generally, once you have defined if the scale function is continuous and in what colorspace, you have variation on the level of control or specification the user will need or can specify. A good example of this is the functions:
*_continuous(),*_gradient(),*_gradient2(), and*_gradientn().
We can start off with continuous scales. These functions are all used when applied to observations that are continuous variables (see above). The functions here can further be defined if they are either binned or not binned. "Binning" is just a way of grouping ranges of a continuous variable to all be assigned to a particular color. You'll notice the effect of "binning" is to change the legend keys from a "colorbar" to a "steps" legend.
The continuous example (colorbar legend):

QUESTION
I have an app that has been running for years with no changes to the code. The app has OAuth2.0 login with a variety of providers including Google Workspace and Office 365. Since the launch of Chrome V97 (i.e. in last few days), the O365 login has stopped working, as for some reason, the auth cookie does not get set in the OAuth callback GET handler. The code that sets the cookie is the same code that is run for Google Workspace, yet this works. It also works on Firefox. Something about Google Chrome V97 is preventing cookies from being set, but only if it round trips to O365 first.
To isolate the issue, I have created a fake callback which manually sets a cookie, thereby removing all of the auth complication. If I call this by visiting the URL in a browser, then the cookie sets as expected. Yet if I perform the O365 OAuth dance first, which in turn invokes this URL, then the cookie does not get set. Try exactly the same thing with Google Workspace and it works.
I have been debugging this for hours and hours and clean out of ideas.
Can anyone shed any light on what could be causing this odd behaviour?
...ANSWER
Answered 2022-Jan-10 at 19:43We ran into this too, fixed by adding SameSite=none; to the auth cookie. In Chrome 97 SameSite is set to Lax if missing. See more here https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Set-Cookie/SameSite
QUESTION
I'd like to abstract some of my GitHub Actions with a reusable workflow.
In order to do this, I need to call my newly defined callable workflow in the format {owner}/{repo}/{path}/{filename}@{ref}
e.g. (from the docs)
...ANSWER
Answered 2021-Oct-20 at 23:55It's as you said: It can't be done at the moment as Github Actions doesn't support expressions with uses attributes.
There is no workaround (yet?) because the workflow interpreter (that also checks the workflow syntax when you push the workflow to the repository) can't get the value from the expression at that moment.
It could maybe work if the workflow was recognized by the interpreter, but it doesn't event appear on the Actions tab as it's considered invalid.
For the moment, you can only use tag, branch ref or commit hash after the @ symbol, the same way you use any action.
QUESTION
So I have a c# class library project that I only intend to use on windows. It contains some classes that use the System.Drawing.Image class which is only available on windows. After upgrading to VS2022 and setting the target framework to .NET 6.0 I'm seeing a bunch of warnings that say CA1416 "This call site is reachable on all platforms. 'SomeClass.SomeMethod' is only supported on: 'windows'. See screenshot below for some examples:
In some sense, it's cool that VS2022 has scanned the library and found all the platform specific code that I'm using in the library. But I'd like to tell VS that I only plan to use the library on windows and it can mute all those warnings.
First I checked the Target Platform options in the properties of the project but didn't seen any windows specific targets.
Then I decided to edit the project's .csproj directly and changed the Target framework from
net6.0
to
net6.0-windows
But sadly even after a recompile, that didn't make the warnings go away either. So then I did some reading on the CA1416 warnings and sure enough it says in the Microsoft Docs that the TFM is ignored for assessing this warning however VS does add an attribute to the project based on the TFM that influences this warning, but it only does so if the project is configured to generate the AssemblyInfo.cs file on the fly. But alas, my project's AssemblyInfo.cs is maintained as a actual file rather then having it auto generated at build time.
So at this point, I'm ready to punt the ball and just disable CA1416 warnings for my project. So in the project's .proj file I added CA1416 for both the release and debug builds like so:
One would think that would be the end of those pesky warnings. (sigh) As it turns out, after rebuilding the project the warnings still show up. Got any suggestions? I'm all ears.
...ANSWER
Answered 2021-Nov-12 at 13:58One way to solve this issue is to create an .editorconfig for the solution and then add the following line to that .editorconfig file:
dotnet_diagnostic.CA1416.severity = none
This will make all "Validate platform compatibility" warnings go away.
QUESTION
Assuming I want to write a function that accepts any type of number in Python, I can annotate it as follows:
...ANSWER
Answered 2021-Sep-29 at 20:20There is no general way to do this. Numbers are not strictly related to begin with and their types are even less.
While numbers.Number might seem like "the type of numbers" it is not universal. For example, decimal.Decimal is explicitly not a numbers.Number as either subclass, subtype or virtual subclass. Specifically for typing, numbers.Number is not endorsed by PEP 484 -- Type Hints.
In order to meaningfully type hint "numbers", one has to explicitly define what numbers are in that context. This might be a pre-existing numeric type set such as int <: float <: complex, a typing.Union/TypeVar of numeric types, a typing.Protocol to define operations and algebraic structure, or similar.
