buffer

问题 Building on this question which discusses flushing a time-based buffer: Force flush to Observable.Buffer c#, I'm having difficulty working out how to translate this answer given there to the case where I'm buffering by count, not by time: var subject = new Subject<Unit>(); var closing = Observable .Timer(new TimeSpan(0, 0, 1, 30)) .Select(x => Unit.Default); var query = mFluxObservable .Buffer(() => Observable .Amb(subject, closing) .Take(1)); I started using the same Amb logic, using an

问题 i am learning directx11 these days. and i have been stuck in compute shader section. so i made four resource and three corresponding view. immutable input buffer = {1,1,1,1,1} / SRV immutable input buffer = {2,2,2,2,2} / SRV output buffer / UAV staging buffer for reading / No View and i succeeded to create all things, and dispatch cs function, and copy data from output buffer to staging buffer, and i read/check data. // INPUT BUFFER1-------------------------------------------------- const int

问题 I got this error after running the following function: function send_buffer(){ ob_end_flush(); ob_flush(); flush(); ob_start(); } The main body of my website takes a few seconds to load, so I want to send the header first. But I got the following error: Notice: ob_flush() [ref.outcontrol]: failed to flush buffer zlib output compression 回答1: You can't use gzip/zlib compression as well as flush. Pick one or the other. I'd recommend gzip rather than flush. 来源： https://stackoverflow.com/questions

问题 I've implemented BufferingAppenderSkeleton in my custom logger class and override SendBuffer method for logging batch logs in the database. Here is an implementation: protected override void SendBuffer(LoggingEvent[] events) { List<Log> logs = new List<Log>(); if (events != null && events.Length > 0) { foreach (var log in events) { var logWithLogSessionId = GetLogWithLogSession(log); logs.Add(logWithLogSessionId); } } Analytics.SaveLogs(logs); } And here web.config configuration for log4net:

问题 I am trying to get data from a TCP Connection (client side only) using Python as programming language, However, I could see that all data are not received in once and are cut in the middle of the receiving process ... I could see on forums that TCP does not send data in the correct order (it is a bit random, link: Python socket receive - incoming packets always have a different size), am I wrong ? My question is if there is anyway to make sure that I correctly received all data? Thanks in

问题 It all started with this question -> How to read blocks of data from a file and then read from that block into a vector? With the aim of minimizing disk I/O operations, I performed a few experiments to see if size of buffer has any kind of effect on the time taken by program. I used the following two codes, one more c-oriented and another more c++ (though both compiled with gcc):- The c oriented code:- int buffer_size=1024; FILE *file; file = fopen(argv[1], "r"); FILE *out_file; out_file =

问题 Greetings Overflowers, I love the flexibility of memory mapped files in that you can read/write any value type. Is there a way to do the same with byte arrays without having to copy them into for e.g. a memory map buffers ? Regards 回答1: You can use the BitConverter class to convert between base data types and byte arrays. You can read values directly from the array: int value = BitConverter.ToInt32(data, pos); To write data you convert it to a byte array, and copy it into the data:

问题 Using Puppeteer (https://github.com/GoogleChrome/puppeteer), I have a page that's a application/pdf . With headless: false , the page is loaded though the Chromium PDF viewer, but I want to use headless. How can I download the original .pdf file or use as a blob with another library, such as (pdf-parse https://www.npmjs.com/package/pdf-parse)? 回答1: Since Puppeteer does not currently support navigation to a PDF document in headless mode via page.goto() due to the upstream issue, you can use

问题 I can't display images longer (height) than about 30612 pixels high. I've read that there is a maximum height to canvas. I'd like to get the source file and extend that to 90 or 100k pixels in height. Conversely, I've seen suggested that a canvas may be buffered, if this is true, I have no clue how to implement it.. Any help is appreciated! I am using code I found off Stack that is supposed to deal with large images, it does alright, but ultimately hit's the cavas height limit. Canvas Limit

问题 I unefficiently use "^a + ESC SPACE -- SPACE" and "^a + ]". 1. How can I copy a big file to GNU Screen buffer like ^a + : cat big_file > new_buffer ^a + : new_buffer ] 2. How can specify the number for each buffer like ^a + : cat big_file 2> new_buffer_number_2 ^a + 2] 回答1: Maybe you want :readbuf ? ^A :readbuf /path/to/file ^A ] I haven't used 'buffers' in GNU Screen (never knew they existed), but I'm guessing :readreg is the buffer-y version of :readbuf : ^A :readreg x /path/to/file ^A
