[ "The implicit system you have to solve is\nk1 = f(y + h*(a11*k1 + a12*k2) )\nk2 = f(y + h*(a21*k1 + a22*k2) )\n\nThis is also correct in your residual function errorFunc.\nThe naive way is just to iterate this system, like any other fixed-point iteration.\nThis system has a linearization rel. h at the base point y\nk1 = f(y) + h*f'(y)*(a11*k1 + a12*k2) + O(h^2)\nk2 = f(y) + h*f'(y)*(a21*k1 + a22*k2) + O(h^2)\n\nSeen as simple iteration, the contraction factor is O(h), so if h is small enough, the factor is smaller than 1 and thus convergence is sure, increasing the order of h in the residual by 1 in each step. So with 6 iterations the error in the implicit system is O(h^6), which is one order smaller than the local truncation error.\nOne can reduce the number of iterations if k1,k2 start with some higher-order estimates, not just with k1=k2=f(y).\n\nOne can reduce the right side residual by removing the terms that are linear in h (on both sides of course).\nk1 - h*f'(y)*(a11*k1 + a12*k2) = f(y + h*(a11*k1 + a12*k2) ) - h*f'(y)*(a11*k1 + a12*k2)\nk2 - h*f'(y)*(a21*k1 + a22*k2) = f(y + h*(a21*k1 + a22*k2) ) - h*f'(y)*(a21*k1 + a22*k2)\n\nThe right side is evaluated at the current values, the left side is a linear system for the new values. So\nK = K - solve(M, rhs)\n\nwith\nK = [ k1; k2]\n\nM = [ 1 - h*f'(y)*a11, -h*f'(y)*a12 ; -h*f'(y)*a21, 1 - h*f'(y)*a22 ]\n = I - h*f'(y)*A\n\nrhs = [ k1 - f(y + h*(a11*k1 + a12*k2) ); k2 - f(y + h*(a12*k1 + a12*k2) )\n = K - f(Y)\n\nwhere \n\nY = y+h*A*K\n\nThis should, probably, work for scalar equations, for systems this involves Kronecker products of matrices and vectors.\nAs the linear part is taken out of the residual, the contraction factor in this new fixed-point iteration is O(h^2), possibly with smaller constants, so it converges faster and, it has been argued, for larger step sizes.\nWhat you have in the code regarding the implicit method step shows the steps of the algorithm in the right order, but with wrong arguments in the function calls.\nWhat you do with h is not recognizable. One could guess that the task is to explore the results of the method for a collection of step sizes. This means that the h for each integration run is constant, halving the step size and increasing the step number for the next integration run.\n" ]

[ "When you use Conan to install a package, the binaries are placed in a directory that Conan calls the \"package cache\". By default, this directory is located at ~/.conan/data/, but you can change its location by setting the CONAN_USER_HOME environment variable.\nTo use the binaries from a package in your project, you'll need to tell your build system (e.g. CMake) where to find them. This is typically done by setting the CMAKE_PREFIX_PATH variable to the package cache directory.\nFor example, if you're using CMake and the package cache is located at ~/.conan/data/, you can add the following line to your CMakeLists.txt file:\nset(CMAKE_PREFIX_PATH \"$ENV{HOME}/.conan/data\")\n\nThis will tell CMake to look in the package cache for any dependencies that your project needs.\nIf you're still having trouble getting your project to build with Conan, I'd recommend checking out the Conan documentation or asking for help on the Conan forums.\n" ]

[ "To ping a website on an Android device when ICMP is blocked, you can use a TCP ping utility instead. A TCP ping sends a TCP packet to the specified host and port, and waits for a reply. This can be used to check if a website is reachable even if ICMP is blocked on the server.\nThere are several TCP ping utilities available for Android, such as TCPing and TCPing Lite. To use one of these utilities, simply enter the hostname or IP address of the website you want to ping, and the port number (typically 80 for HTTP or 443 for HTTPS). The utility will then send a TCP packet to the specified host and port and display the results, including the response time and any errors that may have occurred.\nAlternatively, you can use the telnet command on Android to perform a TCP ping. This can be done by opening a terminal emulator app and running the following command:\ntelnet <hostname or IP address> <port>\n\nFor example, to ping the Google website on port 80, you would run the following command:\ntelnet google.com 80\n\nThis will establish a TCP connection to the specified host and port, and display any output or errors that occur. You can then press CTRL + ] to exit the telnet session.\nNote that using a TCP ping may not provide the same level of accuracy as an ICMP ping, as it does not measure the actual network latency or packet loss. However, it can still be useful for checking if a website is reachable when ICMP is blocked.\n" ]

Since my service was local, I ended up simply using a static field in the service class to toggle state, as described by hackbod here\nEDIT (for the record):\nHere is the solution proposed by hackbod:\n\nIf your client and server code is part of the same .apk and you are \n binding to the service with a concrete Intent (one that specifies the \n exact service class), then you can simply have your service set a \n global variable when it is running that your client can check. \nWe deliberately don't have an API to check whether a service is \n running because, nearly without fail, when you want to do something \n like that you end up with race conditions in your code. \n\n", "Got it! \nYou MUST call startService() for your service to be properly registered and passing BIND_AUTO_CREATE will not suffice.\nIntent bindIntent = new Intent(this,ServiceTask.class);\nstartService(bindIntent);\nbindService(bindIntent,mConnection,0);\n\nAnd now the ServiceTools class:\npublic class ServiceTools {\n private static String LOG_TAG = ServiceTools.class.getName();\n\n public static boolean isServiceRunning(String serviceClassName){\n final ActivityManager activityManager = (ActivityManager)Application.getContext().getSystemService(Context.ACTIVITY_SERVICE);\n final List<RunningServiceInfo> services = activityManager.getRunningServices(Integer.MAX_VALUE);\n\n for (RunningServiceInfo runningServiceInfo : services) {\n if (runningServiceInfo.service.getClassName().equals(serviceClassName)){\n return true;\n }\n }\n return false;\n }\n}\n\n", "A small complement is:\nMy goal is to know wether a service is running without actualy running it if it is not running.\nCalling bindService or calling an intent that can be caught by the service is not a good idea then as it will start the service if it is not running.\nSo, as miracle2k suggested, the best is to have a static field in the service class to know whether the service has been started or not.\nTo make it even cleaner, I suggest to transform the service in a singleton with a very very lazy fetching: that is, there is no instantiation at all of the singleton instance through static methods. The static getInstance method of your service/singleton just returns the instance of the singleton if it has been created. But it doesn't actualy start or instanciate the singleton itself. The service is only started through normal service start methods.\nIt would then be even cleaner to modify the singleton design pattern to rename the confusing getInstance method into something like the isInstanceCreated() : boolean method.\nThe code will look like:\npublic class MyService extends Service\n{\n private static MyService instance = null;\n\n public static boolean isInstanceCreated() {\n return instance != null;\n }//met\n\n @Override\n public void onCreate()\n {\n instance = this;\n ....\n }//met\n\n @Override\n public void onDestroy()\n {\n instance = null;\n ...\n }//met\n}//class\n\nThis solution is elegant, but it is only relevant if you have access to the service class and only for classes iside the app/package of the service.

Here is an example of how you might do this:\nimport subprocess\nfrom os import getlogin\n\n# Spawn a new shell process\np = subprocess.Popen(['cmd'], stdin=subprocess.PIPE, stdout=subprocess.PIPE)\n\n# Change the working directory to the user's home directory\np.stdin.write(f'cd C:/Users/{getlogin()}\\n')\n\n# Run the pip freeze command\np.stdin.write('pip freeze\\n')\n\n# Read the output of the command\noutput = p.stdout.read()\n\n# Print the output to the console\nprint(output)\n\nIn this example, the subprocess module is used to spawn a new shell process and create stdin and stdout streams for interacting with the command prompt.

It often seems like a translation will be a drop-in replacement, but since the libraries and structures you'll use in the new language are different enough that you are just going to make new bugs. Since you are going to make new bugs anyway, you might as well do something smarter.\nBut, I know nothing about your situation, so let's get to the literal question.\nYou're looking at:\n# Read data from a file handle\nsub read_from_client {\n my($self, $buff, $len, $offset) = @_;\n local $^W=0; # prevent a warning\n return $MOD_PERL\n ? $self->r->read($$buff, $len, $offset)\n : read(\\*STDIN, $$buff, $len, $offset);\n}\n\nInstead of worrying about the Perl code, just do whatever you need to do in Python to satisfy the interface. Given a buffer and a length, get some more data from the filehandle. Since you are not handling mod_perl (I'm guessing, because how would you?), you can ignore most stuff there.\n\nThe \\*main::STDIN and \\*STDIN are references to a typeglob, which is a way to track all the Perl variables with the same name (scalar, array, hash, subroutine, filehandle, and a few others). The STDIN identifier is a special case variable that is main by default, so adding the package main:: in front is probably merely developer comfort.\nWhen you use those reference in a place that wants to work on a filehandle, the filehandle portion of the type glob is used. It's just a way to pass the identifier STDIN and have something else use it as a filehandle.\nYou see this as a way to pass around the named, standard file handles.\nThe read takes a filehandle (or reference to typeglob) as its first argument.\nIn python, you'd do something like sys.stdin.read(...).\n", "The following can usually be used a file handle:\n\nAn IO object (*STDIN{IO})\nA glob containing an IO object (*STDIN)\nA reference to a glob containing an IO object (\\*STDIN)\nThe name of a glob containing an IO object (\"STDIN\")\n\nThe builtin operators that expect a file handle allow you to omit the * when providing a glob. For example, read( FH, ... ) means read( *FH, ... ).\nThe builtin functions that expect a file handle should accept all of these. So you could any of the following:\n\nread( *STDIN{IO}, ... )\nread( STDIN, ... )\nread( *STDIN, ... )\nread( \\*STDIN, ... )\nread( \"STDIN\", ... ).\n\nThey will have the same effect.\n\nThird-party libraries probably accept the globs and reference to globs, and they should also expect IO objects. I expect the least support for the providing the name as a string. Your mileage may vary.\nYou can't go wrong with a reference to a glob (\\*FH) since that's what open( my $fh, ... ) produces.\n" ]

[ "\nWhich memory layout is used for variables in shared memory? std140, std430 or something else?\n\nIt's implementation-defined.\nThe layouts applied to buffer-backed storage matter because code external to the shader needs to be able to access it. shared variables cannot be externally to the shader, so the layout of such variables is functionally implementation-defined.\nIn short, you cannot know for certain how much storage any particular shared variable declaration will consume. You can assume that it will take up at least as many bytes as is minimally required to store the data you asked to store. But that's about it.\n\nHow does this play with bank conflicts?\n\n\"Banks\" are not a concept which OpenGL or GLSL recognizes. It is therefore implementation-defined.\n" ]

[ 1 ]

[ "The amount of shared memory that will be used by a given declaration depends on the type and number of variables declared in the shared memory block. In the example you provided, the shared memory block will use 4480 bytes of shared memory.\nThe memory layout used for variables in shared memory is std140. This means that each basic type (e.g. float, int, etc.) is stored as a sequence of contiguous memory locations with specific alignment requirements. For example, a float value must be aligned to a 4-byte boundary, and a vec3 value (three float values) must be aligned to a 16-byte boundary.\nAs for bank conflicts, they can occur when multiple threads in a CUDA block try to access the same memory bank in shared memory simultaneously. This can cause performance degradation because only one thread can access a given memory bank at a time. To avoid bank conflicts, it is important to ensure that variables are laid out in shared memory in a way that avoids conflicts. For example, by aligning variables to multiples of their size, or by using padding to ensure that different variables are mapped to different memory banks.\nTo determine the amount of shared memory used by a program, you can use the GL_SHADER_STORAGE_BUFFER_OFFSET_ALIGNMENT and GL_SHADER_STORAGE_BUFFER_SIZE parameters of the glGetProgramiv function. These parameters will give you the alignment and size of the shared memory block, respectively.\nYou can use these values to calculate the amount of shared memory used by a given program, and to determine the memory layout of the variables in the shared memory block. However, this is an indirect way of doing it, and it may not be possible to determine the exact memory layout of the variables in the shared memory block. For this, you would need to use a debugging tool that can provide more detailed information about the memory layout of variables in shared memory.\n" ]

This is incorrect. The proper mathematical formula is:\ndiscounted cost = full price - discount\n\nTo fix this, the line\nconstexpr double types[3] = { 0.10, 0, 0.15 };\n\nshould be changed to:\nconstexpr double types[3] = { 0.90, 1.00, 0.85 };\n\n" ]

[ "\nA network interface is a physical or logical device that enables a computer or other device to connect to a network and exchange data with other devices on the network. This can include a wide variety of devices, such as Ethernet cards, wireless adapters, and virtual network interfaces.\n\nNetwork interfaces simplify network administration by providing a standard way for devices to connect to a network and communicate with each other. This allows network administrators to easily configure and manage network connections without having to worry about the specific details of each device's hardware or software.\n\nNetwork interfaces correspond to network protocols and their OSI layers in that they provide the physical connection and data transmission capabilities that allow the protocols to operate. For example, an Ethernet interface would correspond to the OSI model's Physical and Data Link layers, while an IP interface would correspond to the Network layer. An interface can represent a \"host\" in an IP network, but it is not required to have an IP address in order to function.\n\nNetwork interfaces and Linux sockets are related in that they both provide a way for a computer to connect to a network and exchange data. However, a network interface is a physical or logical device that provides the actual connection to the network, while a socket is a software abstraction that allows applications to access the network through the interface. When sending data over a socket, a specific interface is not necessarily selected, as the socket API provides a way for the application to specify the destination address and let the operating system choose the appropriate interface.\n\nThe loopback interface is a special interface that is used to communicate with the local host rather than with other devices on the network. This allows a device to send and receive data to itself, which can be useful for testing and development purposes. The loopback address (127.0.0.1) is typically associated with this interface and is used to identify the local host when sending data over the loopback interface.\n\nA typical reason for defining a new network interface on a server would be to add additional network connectivity or to improve network performance. For example, a server might have multiple network interfaces to allow it to connect to multiple networks or to provide failover capabilities in case one of the interfaces goes down. Additionally, a server might use multiple interfaces to increase its overall network bandwidth or to separate different types of traffic onto different interfaces to improve performance.\n\n\nAlso check Official Internet Protocol Standards and Introduction to Network Interfaces\n" ]

[ "Here is a simple outline for implementing the task scheduling problem using heuristic and genetic algorithms in C++ and Python.\nFor the heuristic algorithm, you can start by creating a class or struct to represent each task and VM. This class or struct should have fields for the task size, deadline, and processing speed of the VM.\nNext, you can implement the heuristic algorithm itself. This will involve mapping tasks to VMs in such a way that the completion time of the last task (makespan) is optimized while meeting the deadline of the tasks. One possible approach is to sort the tasks by deadline and then assign them to the fastest VMs until they are all mapped. If a task cannot be mapped before its deadline, it must be rejected.\nTo evaluate the performance of the heuristic algorithm, you can run it multiple times and keep track of the average, maximum, and minimum makespan values. You can also print these values to an Excel file for comparison with the results of the genetic algorithm.\nFor the genetic algorithm, you can start by implementing a function to generate a random initial population of task-to-VM mappings. This function should create a set of mappings that meet the deadlines of the tasks and have a reasonable makespan.\nNext, you can implement the genetic algorithm itself. This will involve applying genetic operators (such as crossover and mutation) to the population of mappings to produce new, improved mappings. You can use a fitness function to evaluate the quality of each mapping and select the best ones for reproduction.\nAs with the heuristic algorithm, you can evaluate the performance of the genetic algorithm by running it multiple times and keeping track of the average, maximum, and minimum makespan values. You can then print these values to an Excel file for comparison with the results of the heuristic algorithm.\nOverall, this problem can be challenging, but it is a good opportunity to learn about algorithms for task scheduling and optimization. I hope this outline helps you get started!\n" ]

[ "The key to constructing an arbitrary structure for scipy.ndimage.label is to understand the concept of a neighborhood. A neighborhood is a set of points in the data that are considered to be connected. For example, in a 2D array, the neighborhood of a point (x,y) is the set of points {(x-1,y-1), (x-1,y), (x-1,y+1), (x,y-1), (x,y), (x,y+1), (x+1,y-1), (x+1,y), (x+1,y+1)}.\nIn order to construct an arbitrary structure for scipy.ndimage.label, we need to define a neighborhood for each point in the data. To do this, we need to define a set of connections between the dimensions of the data. For example, if we have a 4D array, and we want to connect dimensions 0 and 1, and dimensions 2 and 3, then our set of connections would be [[0,1],[2,3]].\nOnce we have defined our set of connections, we can construct our structure tensor. The structure tensor is a 3D array, where the first two dimensions correspond to the dimensions of the data, and the third dimension corresponds to the connections between the dimensions. For example, if we have a 4D array, and we want to connect dimensions 0 and 1, and dimensions 2 and 3, then our structure tensor would be of size (4,4,2).\nThe structure tensor is constructed by setting the elements of the third dimension to 1 if the corresponding dimensions are connected, and 0 otherwise. For example, if we have a 4D array, and we want to connect dimensions 0 and 1, and dimensions 2 and 3, then our structure tensor would be:\n[[[1, 0],\n [0, 0],\n [0, 1],\n [0, 0]],\n \n [[0, 0],\n [1, 0],\n [0, 1],\n [0, 0]],\n \n [[0, 1],\n [0, 0],\n [1, 0],\n [0, 0]],\n \n [[0, 0],\n [0, 0],\n [0, 1],\n [1, 0]]]\n\nOnce we have constructed our structure tensor, we can pass it to scipy.ndimage.label to generate the connected regions of our data.\n", "This should work for you\n\ndef construct_arbitrary_structure(ndim, dim_connections):\n #Create structure array\n structure = np.zeros([3] * ndim, dtype=int)\n\n #Fill structure array\n for d in dim_connections:\n if len(d) > 1:\n # Set the connection between multiple dimensions\n for i in range(ndim):\n # Create a unit vector\n u = np.zeros(ndim, dtype=int)\n u[i] = 1\n\n # Create a mask by adding the connection between multiple dimensions\n M = np.zeros([3] * ndim, dtype=int)\n for j in d:\n M += np.roll(u, j)\n structure += M\n else:\n # Set the connection for one dimension\n u = np.zeros(ndim, dtype=int)\n u[d[0]] = 1\n structure += u\n\n #Make sure it's symmetric\n for i in range(ndim):\n structure += np.roll(structure, 1, axis=i)\n\n return structure\n\n", "o construct the arbitrary structure with the desired connectivity, you can use a loop to iterate over the dimensions and create a 3-D structure that is the default 2-D structure in the dimensions that need to be connected, and a 1-D structure (i.e. a line) in the other dimensions. For example:\nimport numpy as np\nfrom scipy import ndimage\n\n# Create the default 2-D structure\ndefault_structure = ndimage.generate_binary_structure(2, 1)\n\ndef construct_arbitrary_structure(ndim, dim_connections):\n# Create an empty structure\n structure = np.zeros((3,)*ndim, dtype=np.int8)\n for dims in dim_connections:\n # Loop over the dimensions that need to be connected\n for d in dims:\n # If the dimension is the first or last in the list, use a 1-D line\n # Otherwise, use the default 2-D structure\n if d == dims[0]:\n structure[(slice(None),)*d + (1,)] = 1\n elif d == dims[-1]:\n structure[(slice(None),)*d + (1,)] = 1\n else:\n structure[(slice(None),)*d + (slice(None),)] = default_structure\n return structure\n\nExample usage\ndim_connections = [[0],[1],[2,3]]\nmy_structure = construct_arbitrary_structure(4, dim_connections)\nprint(my_structure)\n\nTo use the structure with scipy.ndimage.label to find connected regions in your data, you can use the structure parameter to specify the structure you want to use for the labeling. For example:\nimport numpy as np\nfrom scipy import ndimage\n\n# Generate some random 4-dimensional boolean data\nX = np.random.random((3, 2, 66, 241)) > 0.5\n\n# Define the structure you want to use\ndim_connections = [[0, 1], [2, 3]]\nmy_structure = construct_arbitrary_structure(X.ndim, dim_connections)\n\n# Use scipy.ndimage.label to find connected regions in your data\nlabeled_regions, num_labels = ndimage.label(X, structure=my_structure)\n\n" ]

[ "Yes, it is possible to search for a list of words in a string using a regular expression. To do this, you can use the | (or) operator to combine multiple regular expressions into a single expression. The | operator will match any of the expressions that come before or after it, so you can use it to create a regular expression that will match any of the words in your list.\nFor example, if you have a list of words [\"cat\", \"dog\", \"bird\"], you could use the following regular expression to search for any of those words in a string:\n# Use the | operator to combine multiple regular expressions\n(?i)(?<=\\b|\\\\n)(cat|dog|bird)\\b\n\n", "Yes, it is possible to search for a list of words in a string using regex. You can use the | character to specify multiple words to search for, like this:\n(?i)(?<=\\b|\\\\n)(cat|dog|bird)\\b\n\nThis regex will match the words cat, dog, or bird, regardless of their case (thanks to the (?i) flag), and will require that they appear as whole words (thanks to the \\b character class).\nNote that the (?<=\\b|\\n) part of the regex is called a lookbehind assertion. It specifies that the word must be preceded by either a word boundary (\\b) or a newline character (\\n). This is useful to ensure that the word is not part of a longer word, but you can omit this part if you don't need it.\nYou can also use a character class to search for a list of words, like this:\n(?i)\\b[catdogbird]\\b\n\nThis regex will match the words cat, dog, or bird, regardless of their case, but only if they appear as whole words. The [] characters specify a character class, which will match any of the characters within it.\n" ]

[ "There are a few ways you can improve your current approach to get real-time updates from the server in your React Native app. One way is to use a technology called websockets, which allows for full-duplex communication between the server and the client. With websockets, the server can push data to the client in real time, without the need for the client to continually poll the server for updates. This can reduce the amount of unnecessary traffic and improve the responsiveness of your app.\nAnother way to get real-time updates from the server is to use a technology called long polling. With long polling, the client sends a request to the server, but the server holds the request open until there is new data to send back to the client. Once new data is available, the server sends a response to the client and the client immediately sends another request to the server. This process continues until the client no longer needs updates, at which point the client can cancel the long polling request.\nYou can also consider using a third-party service that specializes in real-time data synchronization, such as Firebase or Pusher. These services provide APIs that you can use in your React Native app to get real-time updates from the server without having to implement websockets or long polling yourself.\nOverall, there is no one-size-fits-all solution for getting real-time updates from the server in a React Native app, so you will need to choose the approach that best fits your specific needs.\n" ]

[ "This error message is telling you that your Python script is unable to write to the Firefox profile that you specified. This could be because the permissions on the profile directory are not set correctly, or because your script is running as a different user than the one who owns the Firefox profile.\nOne way to fix this would be to make sure that your script has the correct permissions to write to the Firefox profile directory. You can do this by changing the ownership of the profile directory to the user that your script is running as, or by changing the permissions on the directory to allow writing by other users.\nAnother option would be to specify the path to a different Firefox profile that your script has permission to write to, or to create a new Firefox profile and use that instead.\nYou may also want to update your code to handle this error more gracefully, by catching the SessionNotCreatedException and either retrying the operation or handling the error in some other way.\nHere is an example of how you could modify your code to handle this error:\nfrom selenium import webdriver\nfrom selenium.webdriver.common.by import By\nfrom selenium.webdriver.support.wait import WebDriverWait\nfrom selenium.webdriver.support import expected_conditions as EC\nimport time\nfrom selenium.webdriver.firefox.options import Options\nfrom datetime import datetime\nfrom selenium.common.exceptions import SessionNotCreatedException\n\n# Open the log file for writing\nf = open(\"/home/username/Documents/AH/log2.txt\", \"a\")\nf.write('gestart')\nf.close()\n\n# Set the URL of the website to scrape\nwebsite = \"https://www.ah.nl/\"\n\n# Create the Firefox options object\noptions = Options()\n# Set the Firefox profile to use\noptions.add_argument('-profile')\noptions.add_argument(r'/home/username/.mozilla/firefox/n2n9yy4r.default-release') \n\n# Try to create a new Firefox session using the specified options\ntry:\n # Create a new Firefox webdriver\n driver = webdriver.Firefox(options=options, service_log_path=\"/home/username/geckodriver.log\")\n # Set the implicit wait timeout to 20 seconds\n driver.implicitly_wait(20)\n # Navigate to the website\n driver.get(website)\n\n # Wait for the element with the specified XPath to be present on the page\n tijd = WebDriverWait(driver,40).until(EC.presence_of_element_located((By.XPATH,\"//*[@id='navigation-header']/div[1]/div[1]/div/div/p/a\")))\n # Get the text of the element\n tijdbezorging = tijd.text\nexcept SessionNotCreatedException:\n # Handle the error by retrying the operation or logging the error\n # You could also try using a different Firefox profile or creating a new one\n print(\"Failed to create Firefox session.

[ "jsPDF is able to use plugins. In order to enable it to print HTML, you have to include certain plugins and therefore have to do the following:\n\nGo to https://github.com/MrRio/jsPDF and download the latest Version.\nInclude the following Scripts in your project:\n\n\njspdf.js\njspdf.plugin.from_html.js\njspdf.plugin.split_text_to_size.js\njspdf.plugin.standard_fonts_metrics.js\n\n\nIf you want to ignore certain elements, you have to mark them with an ID, which you can then ignore in a special element handler of jsPDF. Therefore your HTML should look like this:\n<!DOCTYPE html>\n<html>\n <body>\n <p id=\"ignorePDF\">don't print this to pdf</p>\n <div>\n <p><font size=\"3\" color=\"red\">print this to pdf</font></p>\n </div>\n </body>\n</html>\n\nThen you use the following JavaScript code to open the created PDF in a PopUp:\nvar doc = new jsPDF(); \nvar elementHandler = {\n '#ignorePDF': function (element, renderer) {\n return true;\n }\n};\nvar source = window.document.getElementsByTagName(\"body\")[0];\ndoc.fromHTML(\n source,\n 15,\n 15,\n {\n 'width': 180,'elementHandlers': elementHandler\n });\n\ndoc.output(\"dataurlnewwindow\");\n\nFor me this created a nice and tidy PDF that only included the line 'print this to pdf'.\nPlease note that the special element handlers only deal with IDs in the current version, which is also stated in a GitHub Issue. It states: \n\nBecause the matching is done against every element in the node tree, my desire was to make it as fast as possible. In that case, it meant \"Only element IDs are matched\" The element IDs are still done in jQuery style \"#id\", but it does not mean that all jQuery selectors are supported.\n\nTherefore replacing '#ignorePDF' with class selectors like '.ignorePDF' did not work for me. Instead you will have to add the same handler for each and every element, which you want to ignore like:\nvar elementHandler = {\n '#ignoreElement': function (element, renderer) {\n return true;\n },\n '#anotherIdToBeIgnored': function (element, renderer) {\n return true;\n }\n};\n\nFrom the examples it is also stated that it is possible to select tags like 'a' or 'li'. That might be a little bit to unrestrictive for the most usecases though:\n\nWe support special element handlers. Register them with jQuery-style\n ID selector for either ID or node name. (\"#iAmID\", \"div\", \"span\" etc.)\n There is no support for any other type of selectors (class, of\n compound) at this time.\n\nOne very important thing to add is that you lose all your style information (CSS). Luckily jsPDF is able to nicely format h1, h2, h3 etc., which was enough for my purposes. Additionally it will only print text within text nodes, which means that it will not print the values of textareas and the like.

There may be printer pre-selected and if user confirms may get this document actually printed. To avoid such situation and to provide PDF without any extras, you need to make PDF file. Probably on the server side. You could have tiny html page with invoice only and convert it to PDF file with headless chrome. It's super easy with puppeteer. No need to install/config chrome, just install npm package puppeteer (managed by chrome team) and run it. Keep in mind this will actually launch real chrome just w/o GUI, so you need to have some RAM & CPU for this. Most servers will be fine with low enough traffic. Here is code sample but this must run on the BACKEND. Nodejs. Also it's slow call, it's resources intensive call. You should run it NOT on api call but e.g. after invoice was created - create pdf for it and store, if pdf was not generated yet, just show message to try again in couple minutes.\nconst puppeteer = require('puppeteer');\n(async () => {\n const browser = await puppeteer.launch();\n const page = await browser.newPage();\n await page.goto('https://your-domain.com/path-to-invoice', {\n waitUntil: 'networkidle2',\n });\n await page.pdf({ path: 'invoice-file-path.pdf', format: 'a4' });\n\n await browser.close();\n})();\n\nLearn more here: https://pptr.dev/\n", "if you need to downloadable pdf of a specific page just add button like this\n<h4 onclick=\"window.print();\"> Print </h4>\n\nuse window.print() to print your all page not just a div\n", "You can use autoPrint() and set output to 'dataurlnewwindow' like this:\nfunction printPDF() {\n var printDoc = new jsPDF();\n printDoc.fromHTML($('#pdf').get(0), 10, 10, {'width': 180});\n printDoc.autoPrint();\n printDoc.output(\"dataurlnewwindow\"); // this opens a new popup, after this the PDF opens the print window view but there are browser inconsistencies with how this is handled\n}\n\n", "As mentioned, you should use jsPDF and html2canvas.

[ "It is likely that the WAF is blocking the request with multiple spaces because it is detecting a potential XSS (Cross-Site Scripting) attack. In a XSS attack, the attacker injects malicious JavaScript code into the web application, which is executed by the victim's browser and can steal sensitive data, such as cookies and passwords.\nOne common way to perform a XSS attack is to inject JavaScript code into the web application by using multiple spaces in the input fields. When the user submits the form, the web application saves the input with the multiple spaces, and when the input is displayed on the page, the browser treats the multiple spaces as HTML whitespace, which is ignored by the HTML parser. However, when the HTML parser encounters the JavaScript code, it treats it as valid HTML and executes it.\nThe user will use spaces to obscure the meaning of the input he is sending and increase the chances of the attack being successful.\nTo prevent this type of attack, WAFs typically use a set of rules and signatures to identify and block input with multiple spaces, because it is a common pattern of XSS attacks. This is why the WAF is blocking the request with multiple spaces, and this is a built-in functionality to prevent cyber attacks.\nTo fix the issue, you can remove the extra spaces from your input fields, or you can use a sanitization library, such as DOMPurify, to sanitize the input and remove the potentially malicious JavaScript code. This will allow the WAF to process the request without blocking it, and it will prevent the XSS attack from being successful.\n" ]

[ "To add data to your state without making a call to the server using RTK query, you can use the update() method of your slice. This method allows you to update your state with new data without dispatching an action.\nFor example, if you have a slice called \"auth\" with a property called \"token\" that you want to update with your authorization token, you can use the following code:\nconst authSlice = createSlice({\n name: 'auth',\n initialState: {\n token: null\n },\n reducers: {\n // Add your reducer functions here\n }\n});\n\n// Get your authorization token from the cookie\nconst token = getTokenFromCookie();\n\n// Update the state with the new token\nauthSlice.update(state => {\n state.token = token;\n return state;\n});\n\nThis will update your state with the new token without making a call to the server. You can then access the token in your state using the select() method of your slice.\nconst token = authSlice.select(state => state.token);\n\nYou can then use the token to set the headers of your API requests.\nconst headers = {\n Authorization: `Bearer ${token}`\n};\n\nBy using the update() method of your slice, you can easily add data to your state without making a call to the server.\n" ]

[ "It looks like you are trying to use the select() function in your cc_library rule to select different source files to compile based on a target configuration. This is a valid use of the select() function. However, the error message you are seeing suggests that Bazel is unable to find any source files to compile in one of the configurations.\nOne possible reason for this error is that the values specified in the define_values attribute of your config_setting rules do not match the keys used in the select() function in your cc_library rule. For example, in your cc_library rule, the keys used in the select() function are :pc and :ecu, but in your config_setting rules, the values specified in the define_values attribute are \"target\": \"pc\" and \"target\": \"ecu\". These values do not match the keys used in the select() function, so Bazel will not be able to find the source files to compile.\nTo fix this error, you will need to ensure that the keys used in the select() function in your cc_library rule match the values specified in the define_values attribute of your config_setting rules. For example, you could change the config_setting rules to use the same keys as in the select() function:\nconfig_setting(\n name = \"pc\",\n define_values = {\n \":pc\" : True,\n }\n)\n\nconfig_setting(\n name = \"ecu\",\n define_values = {\n \":ecu\" : True,\n }\n)\nWith these changes, Bazel will be able to find the source files to compile in each configuration. You can then build your target using the bazel build command as before, passing the appropriate --define flag to specify the target configuration.\nI hope this helps!

This is why the ensureInitialized() method is often placed in the main() function of a Flutter app.\nHowever, not all plugins require the ensureInitialized() method. For example, the shared_preferences and device_info_plus plugins do not require access to platform-specific channels, so they do not need the ensureInitialized() method to be called. The xmpp_plugin may or may not require the ensureInitialized() method depending on its specific implementation and the features it uses.\nIn general, it is a good practice to call the ensureInitialized() method in the main() function of a Flutter app if any of the plugins used by the app require it. This ensures that the app is properly initialized and all the necessary platform-specific channels are set up before the app starts running.\n", "Most plugins should not require WidgetsFlutterBinding.ensureInitialized because the WidgetsFlutterBinding instance normally is initialized automatically. Some plugins require that it be explicitly called because they need the instance to be initialized earlier.\nFrom the WidgetsFlutterBinding.ensureInitialized documentation:\n\nYou only need to call this method if you need the binding to be initialized before calling runApp\n.\n\n" ]
