Elsewhere, clustered regularly interspaced short palindromic repeats-based systems have been used to create mutable barcodes to allow multilevel lineage recording without the need for successive rounds of cell labeling68,69. Given its versatility and ease of use, we envision that CellTag-multi can ...

Using the ScreenCaptureKit API on macOS 15.1.0 with an M3 chip causes a freeze of over 40 seconds. 1.Open the DingTalk macOS application, start a meeting, and initiate screen sharing. 2.The DingTalk app calls the [SCShareableContent getShareableContentWithCompletionHandler:] API. 3.The API ...
Just to make sure this sinks in: had I assigned pn the address of local variable, I would have been in trouble again even after capturing pn by value: 複製 // Bad! void foo() { int n = 10; int *pn = &n; task<void> t([pn] () { printf("%d\n", *pn); delete pn; }...
Note that the lambda is passedby valuetocapture, so a copy is made each time you use it. This means that your lambda probably shouldn’t have any mutable state, because the mutations are made to a copy of the original. It also means that your lambda probably shouldn’t capture objects ...

Metadata for a file output is represented by an array of AVMetadataItem objects; you use an instance of its mutable subclass, AVMutableMetadataItem, to create metadata of your own. AVCaptureMovieFileOutput *aMovieFileOutput = <#Get a movie file output#>; NSArray *existingMetadataArray = a...
For many applications, this is as much detail as you need. For some operations, however, (if you want to monitor the power levels in an audio channel, for example) you need to consider how the various ports of an input device are represented and how those ports are...
