I've been trying to do strikethrough with Unicode. I'm finding that the composed characters are to the right of where they "should" be, and somewhat too low, see the examples on our article, and in the
combining character article, these are not in the correct position to be a traditional strikethrough. In fact the tools I've used work best if the struck through text is preceded with a "space strikethrough" (and no strikethrough at the end?). Is there a better solution in Unicode?
All the best:

I'm working on a project that would go lot more smoothly if I could get myself organized. What I've got is pieces of text that I need to be able to classify in various ways and apply attribute tags to (e.g. this text has the tags applied for "Religion" and "Finances" while this other one has only "Animals", etc.). I would normally use Excel for something of this scale, but the text pieces aren't really appropriate for stuffing into a cell (and some have particular formatting I'd like to preserve, which again doesn't work great with Excel). At this point, my plan is to indeed do it in Excel, but hyperlink the text pieces, which is clunky at best. Any other options that spring to mind? There will be hundreds of records, which is large enough to need organization, but not zillions and zillions and it's a personal project, so I'm not looking to spend a lot. Any programs spring to mind as appropriate? Matt Deres ( talk) 14:58, 23 May 2024 (UTC)
Org mode has sufficed for me, but maybe you need something fancier for more complicated info. The general approach is
Zettelkasten and there is a lot different software for it, none of which I've used.

In social media, many simple texts go viral which have nothing special other than they are blown up to a picture. People may forward them because (a) it's dead easy and (b) they find them funny or they want to proselytize the expressed opinion to others. What are they called? You might consider them a subgroup of internet memes. However, they don't fit the definition “Two central attributes of Internet memes are creative reproduction and intertextuality.”, nor do they contain any other noteworthy creativity. Their only purpose seems to be that they're bigger than normal text so that they gather more importance. Even “eye candy” would be too flattering, so I'd rather call them "rectangular attention sinks". Maybe I'd better turn to a sociologist with this question.

English Wikipedia is almost at 1,225,620,000 diffs, increasing at about 1000 every ten minutes or so I'm guessing. Is there a limit to this number in MediaWiki or the underlying software – cognate with the Y2K problem and the like?

I am using Windows 11, and Word for Microsoft 365. My question has to do with the feature to Save Autorecovery information, which saves a copy of each Word document that is open and has been modified within the past 10 (or other user-settable time) minutes. These Autorecovery files are saved in Appdata \ Roaming \ Microsoft \ Word. However, if I look at them as I am editing various Word documents, sometimes I notice that some of them have sizes of 0 KB. I am attaching a screen shot showing a view of the Word folder with four documents having sizes of 0 KB. These files are in fact null files; that is, the 0 KB is correct. The files that I was editing were not null files.
What causes Word to stop creating good Autorecovery files? What I have found I can do is to stop Word (after saving the documents in question to their disk locations), and restart Word. If there is an unexpected stop or unexpected loss of Word functionality, updates to the documents being edited are lost.
Is there technical documentation of the Autorecovery feature? Does anyone know what causes these failures, or how to minimize their occurrence? Robert McClenon ( talk) 03:36, 26 May 2024 (UTC)
What is the Roaming directory?That is displayed in the screen shot that occupies too much space just above this discussion. It is a subdirectory of my User directory, and, as you imply, it has something to do with network access, but appears to be an old version of network access. I have changed the directory in which the Autosave is being done,and will see if that accomplishes anything. I think that we are both inferring that what was happening was that the Word subdirectory within the Roaming subdirectory had exceeded some size limit, which would be why the Autorecovery files were being zeroed. You provided some useful information to guess at what to do. Robert McClenon ( talk) 16:38, 28 May 2024 (UTC)

I was watching TV the other day and they showed a computer screen with code on it. Normally, I rewind the program to see what language they are using. However, I came across a language I don't recognize. It looks like they are using # signs for comments, CIF to terminate IF blocks, == for testing equality, & and | for compound conditions, = for assignment and maybe line numbers for a couple lines.

Let's say I allocate a new array
std::array<int,10> *x = new std::array<int,10>;
Considerable head scratching at cppreference.com doesn't tell me whether this array's elements are guaranteed to be initialized to 0. Experimentally they do seem to be, but that could be accidental. In C, of course, int x[10]; makes an array that is uninitialized. Does anyone know? Thanks. 2601:644:8501:AAF0:0:0:0:1ECE ( talk) 05:14, 1 June 2024 (UTC)
By default, regular arrays of local scope (for example, those declared within a function) are left uninitialized. This means that none of its elements are set to any particular value. I don't know what happens in a global scope. ― Panamitsu (talk) 06:33, 1 June 2024 (UTC)
note that default initialization may result in indeterminate values for non-class T", and the default initialization reference linked above clarifies that POD types ("plain old data", like int) are uninitialized by default initialization. So for a std::array<T> created without an initialization list, the elements are uninitialized if T is a POD type. If T is a non-POD class, the elements would be initialized with their default constructor. CodeTalker ( talk) 05:53, 2 June 2024 (UTC)
Zero-initialization is performed in the following situations: 1) For every named variable with static or thread-local(since C++11) storage duration that is not subject to constant initialization, before any other initialization.
()
(chosen via overload resolution) is called with an empty argument list to initialize the class (9.4.1 (7.1)).array
class is an aggregate, and uses the implicitly-declared default constructor (24.3.7.2 (1)).{142857, -32768}
. IF one assumes that the class holds an array of 10 int
s with no initializer specified (which seems more likely), that array is itself default-initialized (11.9.3 (9.3)); each element thereof is then also default-initialized (9.4.1 (7.2)). For an int
, default-initialization performs no initialization (9.4.1 (7.3)), and we are left with whatever was in the memory we were allocated.
// --- static; no initializer
static std::array<int,10> a; // initialized to 0
static std::array<MyClass,10> a; // initialized by MyClass::MyClass()
// --- static; empty initializer (same as previous case)
static std::array<int,10> a{}; // initialized to 0
static std::array<MyClass,10> a{}; // initialized by MyClass::MyClass()
// --- local; no initializer
std::array<int,10> a; // uninitialized
std::array<MyClass,10> a; // initialized by MyClass::MyClass()
// --- local; empty initializer
std::array<int,10> a{}; // initialized to 0
std::array<MyClass,10> a{}; // initialized by MyClass::MyClass()
// --- heap; no initializer
std::array<int,10> *a = new std::array<int,10>; // default initialized (uninitialized)
std::array<MyClass,10> *a = new std::array<MyClass,10>; // default initialized: initialized by MyClass::MyClass();
// --- heap; empty initializer
std::array<int,10> *a = new std::array<int,10>(); // value initialized (set to zero)
std::array<MyClass,10> *a = new std::array<MyClass,10>(); // value initialized: also initialized by MyClass::MyClass();
BTW, the "experiment" by which the OP found their array to be set to zero would be better done by deliberately unzeroing the heap first, by something like
std::array<int,100> *z = new std::array<int,100>;
for (int i = 0; i < 100; ++i) (*z)[i] = 0xffffffff;
delete z;
A couple of examples for context:
What is the word for a set of parameters which attribute to an instance/snapshot the information required for it's reproduction?
In the examples above, ccache utilises "different kinds of information that should be unique for the compilation", similarly if I save a webpage from within a Web Browser, the only way for someone to be guaranteed to independently replicate the same file would be for the same URI to be accessed by the same version of the Web Browser with the same configuration (e.g. javascript enabled/disabled, identical installation+configuration of extensions which affect page retrieval/rendering) on the same Operating System with the same configuration.
In the case of ccache, the compiler version and flags are some factors of the "information that should be unique for the compilation", and during recompilation inputting the same selection of information results in an identical hash and therefore a cache match.
But what is the word to describe the information being input?
I'm not looking for a generic word like "metadata".
Some words I thought of which seemed to be candidate answers were:

Can I use it to reconstruct a screenshot of what you saw? No. I don't know if you used a laptop or a smartphone. Suppose I know you used a MacBook. Which type of many types? Which size of screen? Produced in which year? (This makes a differences for some types.) Which release of macOS were you using, and which version of that release? Likewise, not only which browser, but also which version? Did your browser have customizations? Was the window full-screen? If not, what were its sizes? How far up or down was the page scrolled, and at which zoom level was it being viewed? Did you watch in dark mode? Knowing all this may still not be enough for a faithful reconstruction of what you saw. Only a screenshot will do. --
