Clash Royale CLAN TAG #URR8PPP Simple string parser in boost::spirit::x3 not working For learning purposes I'm trying to write a simple parser that accepts a string literal and puts it in a custom struct using the x3 library from boost. However, the following minimal example which is adapted from the example here does not compile. #include <iostream> #include <boost/spirit/home/x3.hpp> #include <boost/fusion/include/adapt_struct.hpp> #include <string> namespace x3 = boost::spirit::x3; namespace ast struct Symbol std::string val; ; BOOST_FUSION_ADAPT_STRUCT( ast::Symbol, val ) namespace parser x3::string("qwe"); BOOST_SPIRIT_DEFINE( symbol ); int main(int argc, char** argv) std::string input = "asd"; if (argc > 1) input = argv[1]; std::string::const_iterator begin = input.begin(); std::string::const_iterator end = input.end(); ast::Symbol sym; bool success = x3::phrase_parse(begin, end, parser::symbol, x3::ascii::space,

Clash Royale CLAN TAG #URR8PPP Command Line Password Prompt in PHP I'm writing a command line tool to help my web app. It needs a password to connect to the service. I'd like the script to show a password prompt so I don't have to pass it as a command line argument. That's easy enough, but I'd like it to not echo the password to the screen as it's typed. How can I do this with PHP? Bonus points for doing it in pure PHP (no system('stty') ) and replacing the characters with * . system('stty') * EDIT: The script will run on a unix like system (linux or mac). The script is written in PHP, and will most likely stay like that. Also, for the record, the stty way of doing it is: stty echo "Password: "; system('stty -echo'); $password = trim(fgets(STDIN)); system('stty echo'); // add a new line since the users CR didn't echo echo "n"; I'd prefer to not have the system() calls in there. system() Wha

Clash Royale CLAN TAG #URR8PPP How do the shuffle/permute intrinsics work for 256 bit pd? I'm trying to wrap my head around how the _mm256_shuffle_pd and _mm256_permute_pd intrinsics work. I can't seem to predict what the results of one of these operations would be. First, for _mm_shuffle_ps all is good. The results I get are the one I expect. For example: float b[4] = 1.12, 2.22, 3.33, 4.44 ; __m128 a = _mm_load_ps(&b[0]); a = _mm_shuffle_ps(a, a, _MM_SHUFFLE(3, 0, 1, 2)); _mm_store_ps(&b[0], a); // 3.33 2.22 1.12 4.44 So everything is right here. Now I wanted to try this with __m256d that is what I'm currently using in my code. From what I've found the _mm256_shuffle_ps/pd intrinsics works differently. My understanding here is that the control mask is applied two times. The first time on the first half of the 128 bit and the second on the last 128 bit. The first two pairs of control bits are used to choose from the first vector ( and store the values in t

Clash Royale CLAN TAG #URR8PPP Credential Provider - how to skip SAS? I implemented my own custom Windows credential provider following the Windows SDK example which should let a remote application connect to a server and perform logon automatically. The problem is: the SetUsageScenario event is not called until a user presses the SAS combination (Ctrl+Alt+Del), therefore my credential provider isn't able to automatically perform the login until that happens. SetUsageScenario How does RDP do the login automatically without me pressing Ctrl+Alt+Del and logging in automatically? How do I do the same with my custom credential provider? 1 Answer 1 SAS can be skipped for Console session only if You turn it off manually in the registry/policies. RDP session always skip SAS and direct You to enter credentials. Moreover modern RDP client asks for credentials prior to establishing connection to remote server. It serialize your credentials and send them to remote server. On serve

Clash Royale CLAN TAG #URR8PPP MPI4PY shared memory - memory usage spike on access I'm using shared memory to share a large numpy array (write-once, read-many) with mpi4py, utilising shared windows. I am finding that I can set up the shared array without problem, however if I try to access the array on any process which is not the lead process, then my memory usages spikes beyond reasonable limits. I have a simple code snippet which illustrates the application here: from mpi4py import MPI import numpy as np import time import sys shared_comm = MPI.COMM_WORLD is_leader = shared_comm.rank == 0 # Set up a large array as example _nModes = 45 _nSamples = 512*5 float_size = MPI.DOUBLE.Get_size() size = (_nModes, _nSamples, _nSamples) if is_leader: total_size = np.prod(size) nbytes = total_size * float_size else: nbytes = 0 # Create the shared memory, or get a handle based on shared communicator win = MPI.Win.Allocate_shared(nbytes, float_size, comm=shared_comm) # Construct the array

Clash Royale CLAN TAG #URR8PPP Use Linq.Dynamic or Expressions to create an new anonymous object I've the following code: public class C public string Field get; set; public string Data get; set; var x = new C Field = "F", Data = "Data 1" ; var y = new C Field = "G", Data = "Data 2" ; And I want to cast this to an anonymous object like: var x_a = new F = "Data 1" ; var y_a = new G = "Data 2" ; Note that the property name (F or G) is the content, so this can change dynamically.

Clash Royale CLAN TAG #URR8PPP Microsoft Access - how change the label of the aggregate function “Totals” in its row I've been trying to do some exercises from a book teaching on how to use MS Access (in my case 2016 version is utilized). In one of the sections, an example is given on how to perform a quick calculation using the aggregate function by clicking the "Totals" buttons from the Record group in the HOME tab, all this on a query displayed in Datasheet View with some records present.

The problem is, that the label at the beginning of the row says "Total", and I cannot seem to be able change it to say something else: Even when I click over the "None" option from the falling options above, the label just remains saying "Total" (I don't know what to expect).
