kandi X-RAY | pcopy Summary
pcopy is a tool to copy/paste across machines. It can be used from the web UI, via a CLI or without a client by using curl. It can also be used as a self-hosted NoPaste or as a temporary file hosting service. After installing the pcopy server, you can use the pcopy command line tool to copy from STDIN (pcp < file.txt) and paste on any connected machine to STDOUT (ppaste > file.txt). If you don't have pcopy installed, you can also use its super simple REST API to copy/paste, e.g. via curl. The web UI allows you to paste text or upload files (even if they are gigabytes in size), and generates temporary links you can share with others. To see what else pcopy can do, check out the live demo (aka nopaste.net) or the videos.

QUESTION
P0847 proposes the possibility of using explicit this parameter for member functions.
Among other great goodies that this proposal brings, there is also the great new possibility for CRTP without C, R and even T.
A common practice for implementing a generic clone in C++ is based on CRTP, see for example this SO post.
Given that we need clone to be virtual (or at least, behave as virtual), to allow:

QUESTION
I am learning Haskell, and as a task for myself I was trying to implement a Universal Machine from ICFP Contest 2006. I came up with a code, which, at a first glance, seems to be working. However, when I try to execute any application for that Universal Machine provided on the contest's website (e.g. sandmark.umz), my implementation is too slow to actually run anything. Self-check did not finish in a couple of hours, and I had to kill the process. So, I am clearly doing something wrong, I just don't know what.
I have tried to use Haskell's profiler, but I couldn't make any sense out of those numbers as well. Garbage collection doesn't seem to be taking a lot of time (3 seconds out of 173 seconds of a sample). However, total allocated memory during those 173 seconds was almost 6 GB, while the maximum heap size was 13 MB.
Could you help me understand, what is wrong with my code? I know that the amount of code is quite large, but I am not sure how to come up with a minimum reproducible example in my case, when I don't really know what is relevant, and what is not. Thank you.
...ANSWER
Answered 2020-Jul-23 at 21:04Total allocation of 3 gigabytes for a Haskell programming running for 176 seconds is miniscule. Most Haskell programs allocate 3-6 gigabytes per second for their entire runtime. In your case, much of the program is running in tight, allocation-free loops (generally a good thing when you're trying to write a fast program), which may explain the small amount of allocation. The small proportion of time spent garbage collecting is also a good sign.
I tested your program on sandmark.umz andcodex.umz, built with -O2 and no profiling.
I believe the main problem is that the hPutStrLn logging lines are generating tons of output, so your universal machine is spending all its time writing logs.
Comment out all the hPutStrLn lines, and SANDmark prints a line every few seconds. I have no idea how fast it's supposed to be, but it's certainly running.
For Codex, it completes the self-check succeeded in a few seconds and accepts a 32-character key. If you enter the wrong key, it prints "wrong key". If you enter the right key, it prints "decrypting..." At this point, it seems to freeze up, so I suspect your implementation is too slow, but not nearly as slow as you were reporting.
Note that you may find it helpful to turn off buffering on stdin and stdout at the start of main:

...ANSWER
Answered 2020-May-04 at 16:41You're best off using pgc++ to link. Compiling main.cpp with g++ is fine, but the PGI compiler at link time will implicitly include some initialization routines that are needed for OpenACC and CUDA interoperability. Without this initialization, you'll see runtime errors like this one.
QUESTION
Whenever I run this code, the data that is pointed (member pData) to within the _TextureData struct is all 0 (like 300 bytes of just 0). The HRESULT result that it returns is always S_OK, and the row and column depths are accurate. I am sure that something is being rendered to the buffer because there are things being displayed on the window that I am rendering to. I have tried both getting the buffer's data before and after presenting, and either way, the data is still null.

QUESTION
We are seeing some strange behavior in GCC with the following code example. The strange behavior is ODR violation in GCC 6.3.0 with types defined in two separate translation units. It is possibly related to recursive type definitions or incomplete types.
We are unsure whether our code is valid, or if we are depending on undefined behavior in the way our types are recursively defined. Please see how the variant-like Dynamic class template is defined and instantiated in two separate cpp files.

I'm trying to develop a script to move (some) files arriving in a directory and log the results. I have the copying part right(I say right - it works - but it could in fact be hopelessly wrong!), but not the logging.
Here's the command line:
PCopy.ps1 -carrier ECM -direction IN -filter DEL, MAN
The first parameter correctly ascertains the directories, the second chooses the sub directory. The third parameter is where it gets interesting, as this is an array.
So what I have come up with is a couple of nested loops:

QUESTION
I have spent the last few days trying to create a generalised wrapper of sorts for function pointers in C++ and I've managed to solve nearly every single issue bar one. My main goal with this was to be able to simply call an object as a function with a function pointer stored internally. If the pointer was pointing somewhere then it would call it as normal while a null pointer would just not call the function and it would continue on as if nothing happened. I intend to use this primarily for callback function purposes, where I would likely not care if the function was called or not and just wanted to preform an action. It works almost perfectly with the following:

I feel I might be missing something really obvious. I need to copy a jagged n-dimensional array in java from one to another primitive (Number) type (e.g., from double[][][][] to int[][][][]). My code below works using Object[]s. How can I (or "Can I even") generate a new type of primitive array of n-dimensions? (By "jagged" I mean some arrays at the same level may have different dimensions as in the example data). Any help appreciated.

Rao (2012, p. 180, listing 8.9) says "The reason you create a copy in Line 10 is so that the loop modifies the pointer being used via the increment operator (++). The original pointer returned by new needs to be stored intact for the corresponding delete[] in Line 26 needs to be invoked using the address returned by new and not any random value".

Answered 2017-May-03 at 23:30There's a few problems here.
It looks like there can be a case where "mid" is greater that "right_end" which will cause a malloc to have a negative size. While I'm not sure it's the correct fix, I added an if statement to skip the merge when mid>right_end.
Parallel loops must be countable, i.e. that the number of iterations is known at the start of the loop. Hence you can't put "loop" directives around while loops.
Putting "arr" in a private clause isn't what you want here. You want to update the global array, not a private copy. Private will make a private copy of the variable for every gang, vector, or worker (depending upon the schedule of the loop with the private clause). The private variable goes away after the kernel executes.
Also your "curr_size" for loop has a dependency so can't be parallelized. The problem here is that it strides by "curr_size=2*curr_size". Each iteration needs the previous iteration's curr_size value before it can compute it's own curr_size.
Note that using "malloc" within a compute region is problematic. First, device side mallocs are very slow so will have an adverse impact on performance. Also, the heap on the device is quite small (default 8MB but can be increased but setting the environment variable PGI_ACC_HEAPSIZE) so very large values of n may overflow the heap and give an illegal address error.
Here's the fixed code:

Install pcopy
To setup a new pcopy server, simply run sudo pcopy setup (see server setup demo):. This will walk you through an interactive setup wizard and place a config file at /etc/pcopy/server.conf (see sample config). The wizard will set up a pcopy user and a systemd service. Once the service is started, it listens on port 2586 by default. If you've enabled the Web UI, you can browse to it an paste text snippets or upload files to it (see live demo).
