QUESTION
I have been trying to learn about functional programming, but I still struggle with thinking like a functional programmer. One such hangup is how one would implement index-heavy operations which rely strongly on loops/order-of-execution.
For example, consider the following Java code:

Answered 2022-Mar-07 at 21:17This is not an index-heavy operation, in fact you can do this with a one-liner with scanl1 :: (a -> a -> a) -> [a] -> [a]

QUESTION
I just updated my Android studio to the version 2021.1.1 Canary 12. After struggling to make it work, I had to also upgrade my Gradle and Gradle plugin to 7.0.2. Now I can compile my project and launch my app on my mobile, everything is working. But when I try to generate a Signed APK, I get a strange message after building telling me: APK(s) generated successfully for module 'android-mobile-app-XXXX.app' with 0 build variants:
Even though the build seem to be successful I cannot find the generated APK anywhere (and considering the time it takes to give me that error, I don't even think it is building anything). Now, I have been generating an APK every week for years now, so I know my way around the folders, the different build variant output folders etc... Nothing changed in my way of generating an APK. I do it via AS and follow the very standard procedure.
Can someone point to me what am I missing here? I assume there is a way to select a specific build variant when generating a signed APK, how does it works?
PS: Obviously, I am selecting my variant here during the process:
PS2: I can generate a debug APK without any issue whatsoever.

QUESTION
Targeting S+ (version 31 and above) requires that one of FLAG_IMMUTABLE or FLAG_MUTABLE be specified when creating a PendingIntent. I got it after updating target SDK to 31. the error always come after AlarmPingSender. But i dont know any class that used AlarmPingSender.
...ANSWER

Upgrade google analytics to firebase analaytics. Hope it'll solve your problems.Also upgrade all the library what're you using.
For me below solutions solve the problem.
Add PendingIntent.FLAG_IMMUTABLE
to your pending intents.
Here is an example -
PendingIntent pendingIntent = PendingIntent.getActivity(this, alarmID, notificationIntent, PendingIntent.FLAG_IMMUTABLE);

QUESTION
When I use .Internal(inspect())
to NA_real_
and NaN
, it returns,
ANSWER
Answered 2021-Dec-24 at 10:45NA
is a statistical or data integrity concept: the idea of a "missing value". Eg if your data comes from people filling in forms, a bad entry or missing entry would be treated as NA
.
NaN
is a numerical or computational concept: something that is "not a number". Eg 0/0 is NAN
, because the result of this computation is undefined (but note that 1/0 is Inf
, or infinity, and similarly -1/0 is -Inf
).
The way that R handles these concepts internally isn't something that you should ever be concerned about.
QUESTION
The undesired functionality
In Chrome 95 there was introduced new functionality where the user can hover and click on the unit part of a css value to hotswap the unit.
The feature is part of a package solution that has been labeled "Length Authoring Tools" in the release notes, and can be seen in action and described in detail in the release notes on the official blog.
How can this feature be disabled?
Issue 1:
If a css-line in the inspector says padding: 0 10px;
then the user can click the px
-part of the line and open a selector that let's the user swap px
to other units such as rem
,vmax
or in
.
Clicking this part of the value no longer lets the user edit the entire value quickly. Most users already know what unit they desire to use beforehand, so they do not need to be helped to accidentally select pt
or vw
when working exclusively with px
everywhere else.
Issue 2:
When selecting and copying properties from the inspector there is now inserted whitespaces/new lines between the value and the unit since the unit portion seems to be considered a separate element. This makes prototyping in the devtools and copy/pasting to external documents very tedious and broken.
ANSWER
Answered 2021-Nov-18 at 14:28Updated answer 2021-11-16:
The following is mentioned in the official release notes for Chrome 96.
To disable Length Authoring Tools, navigate to this location in the DevTools and uncheck the checkbox:
Settings > Experiments > Enable CSS length authoring tools in the Styles pane.
But... The main issues regarding Length Authoring Tools have also been fully remedied in Chrome 96.
The initial incentive to disable these tools has been greatly diminished because of this.
A chevron will now appear to the right of the hovered value instead of reacting to clicks to the entire unit portion of it.
Copy paste now also works as intended.
Conclusion:
It is now possible to disable the Length Authoring Tools, but you might no longer need to.
Old answer:
You can't. (Though fixes are coming!)It is not possible to toggle this feature in the current live stable release ( Chrome 95.0.4638.69 ).
Fixes have been added to Chromium ( [1], [2], [3] ) that are slowly making their way to the stable release of Chrome.
But help is on its way...
Chrome 96 is scheduled to be released on November 16 2021 (source), or ~3 weeks after October 28 according to this official tweet. It will at least contain a revert to free text editing of css properties (source). Hopefully version 96 will address the issue completely, but if it doesn't then the next major release is scheduled for January 4 2021 (If this issue is unresolved by then somebody at Google should be fired).
As for now, Chrome Canary seems to have these fixes implemented and might be considered an alternative solution to the issue if you find the current state of Length Authoring Tools unbearable.
Please be advised that Chrome Canary can be quite unstable.
This question and answer will be edited and corrected once there are real fixes in the live stable version.
QUESTION
I am aware of how ODR, linkage, static
, and extern "C"
work with functions. But I am not sure about visibility of types since they cannot be declared static
and there are no anonymous namespaces in C.
In particular, I would like to know the validity of the following code if compiled as C and C++
...ANSWER
Answered 2021-Oct-20 at 09:43For C. The program is valid. The only requirement that applies here is "strict aliasing rule" saying that the object can be accessed only via a l-value of a compatible type (+ a few exception described in 6.5p7).
The compatibility of structures/unions defined in separate translation units is defined in 6.2.7p1.
... two structure, union, or enumerated types declared in separate translation units are compatible if their tags and members satisfy the following requirements: If one is declared with a tag, the other shall be declared with the same tag. If both are completed anywhere within their respective translation units, then the following additional requirements apply: there shall be a one-to-one correspondence between their members such that each pair of corresponding members are declared with compatible types; if one member of the pair is declared with an alignment specifier, the other is declared with an equivalent alignment specifier; and if one member of the pair is declared with a name, the other is declared with the same name. For two structures, corresponding members shall be declared in the same order. For two structures or unions, corresponding bit-fields shall have the same widths. For two enumerations, corresponding members shall have the same values.
Therefore the structures are not compatible in the example.
However, it is not an issue because the f
object is created and accessed via locally defined type. UB would be invoked if the object was created with Foo
type defined in one translation unit and accessed via other Foo
type in the other translation unit:
QUESTION
Consider the following C++17 code:
...ANSWER
Answered 2021-Oct-03 at 12:09The code shown is valid (all C++ Standard versions, I believe). The similar restrictions are all listed in [reserved.names]. Since read
is not declared in the C++ standard library, nor in the C standard library, nor in older versions of the standard libraries, and is not otherwise listed there, it's fair game as a name in the global namespace.
So is it an implementation defect that it won't link with -static
? (Not a "compiler bug" - the compiler piece of the toolchain is fine, and there's nothing forbidding a warning on valid code.) It does at least work with default settings (though because of how the GNU linker doesn't mind duplicated symbols in an unused object of a dynamic library), and one could argue that's all that's needed for Standard compliance.
We also have at [intro.compliance]/8
A conforming implementation may have extensions (including additional library functions), provided they do not alter the behavior of any well-formed program. Implementations are required to diagnose programs that use such extensions that are ill-formed according to this International Standard. Having done so, however, they can compile and execute such programs.
We can consider POSIX functions such an extension. This is intentionally vague on when or how such extensions are enabled. The g++ driver of the GCC toolset links a number of libraries by default, and we can consider that as adding not only the availability of non-standard #include
headers but also adding additional translation units to the program. In theory, different arguments to the g++ driver might make it work without the underlying link step using libc.so
. But good luck - one could argue it's a problem that there's no simple way to link only names from the C++ and C standard libraries without including other unreserved names.
(Does not altering a well-formed program even mean that an implementation extension can't use non-reserved names for the additional libraries? I hope not, but I could see a strict reading implying that.)
So I haven't claimed a definitive answer to the question, but the practical situation is unlikely to change, and a Standard Defect Report would in my opinion be more nit-picking than a useful clarification.
QUESTION
A class in C++ can define one or several conversion operators. Some of them can be with auto-deduction of resulting type: operator auto
. And all compilers allow the programmer to mark any operator as deleted, and operator auto
as well. For concrete type the deletion means that an attempt to call such conversion will result in compilation error. But what could be the purpose of operator auto() = delete
?
