Vector API is a new feature introduced in Java 18 that provides a set of vectorized operations that can be used to accelerate mathematical computations. Vector API enables developers to write code that can take advantage of the latest hardware, including CPUs with vector units and GPUs. Vector API provides a set of classes and interfaces that can be used to write code that performs vectorized operations on arrays of numeric data. The API supports operations such as addition, multiplication, and division, as well as more complex operations such as dot products, norms, and reductions. The API also includes support for complex numbers and floating-point operations. Here's an example of how Vector API can be used to accelerate a simple mathematical operation: import jdk.incubator.vector.*; public class VectorExample {     public static void main(String[] args) {         float[] a = {1.0f, 2.0f, 3.0f, 4.0f};         float[] b = {5.0f, 6.0f, 7...

Pattern Matching for switch Statements is a new feature introduced in Java 18 that allows developers to use patterns as case labels in switch statements. This feature was first introduced as a preview feature in Java 14 and was further improved in Java 15 and Java 17 before being made a permanent feature in Java 18. Prior to Java 18, switch statements could only use primitive types, enums, and strings as case labels. With pattern matching, developers can now use patterns, which are more flexible and powerful than simple literals. Patterns allow developers to match against more complex conditions, such as types, values, and structures. Here's an example of how pattern matching works: public String getAnimalSound(Animal animal) {     String sound = switch (animal) {         case Cat c -> "Meow";         case Dog d -> "Woof";         case Lion l -> "Roar";         default -> throw new Ille...

I'm running into an issue when connecting to a MySQL database on Amazon Linux 2 using pyodbc and the mysql-connector-odbc driver. As shown below: pyodbc.OperationalError: ('08004', "[08004] [unixODBC][MySQL][ODBC 5.2(w) Driver]Authentication plugin 'caching_sha2_password' cannot be loaded: /usr/lib64/mysql/plugin/caching_sha2_password.so: cannot open shared object file: No such file or directory (2059) (SQLDriverConnect)") I tried upgrading my Amazon Linux version to 2.0.20230207.0 , but got a similar error: pyodbc.OperationalError: ('08004', "[08004] [unixODBC][MySQL][ODBC 5.2(w) Driver]Authentication plugin 'sha256_password' cannot be loaded: /usr/lib64/mysql/plugin/sha256_password.so: cannot open shared object file: No such file or directory (2059) (SQLDriverConnect)") My understanding is this is because the version of MySQL server is using a newer version than what my ODBC driver supports. I would love to upgrade the ODB...

I am trying to automatically notify my coworkers when their work is seven days away from being due. There are two tables on the same sheet (one sheet per coworker). How can I send an email based on two different tables on the same sheet? For example, Bill has treatment plans that will be due. He also has assessments that will be due. The treatment plans are in one table and the assessments are in another table on the same sheet (Sheet2 Bill). I want an email sent to Bill when a treatment plan is seven days away from the due date. I want a different email sent to Bill when an assessment is seven days away from the due date. I am not seeing any error messages, but I am also not receiving any emails. Client name is the B column. This is a sample line from my table: Sub email() Dim r As Range, cell As Range Dim ws As Worksheet Dim Mail_Object As Object, Mail_Single As Object Dim Email_Subject As String, Email_Send_From As String, Email_Send_To As String, _ Email_Cc As String, E...

I new in Kafka and Python but I should create consumer:) I created simple consumer and got result, but the data in Kafka is store in Avro that's why I need to make deserialization.

Presently, I've installed MediaWiki on a wiki which includes a section with a timeline of modern historic events in basically every article. It's important to display the precise time of day of these global historic events in a meaningful way and I anticipated this would be easy to accomplish. Presently, I am converting timestamps of events into my current local time and typing them as plain text in the article when I make edits. This works great for me, but most other users of the wiki will be in different timezones and I'd rather not arbitrarily declare my local timezone as the "ultimate source of global truth" and force everyone else around the world to convert all times to my local timezone. Similarly, I could convert all the times to UTC but, in fact, the majority of users I anticipate won't be from Europe. I could use Eastern time, but honestly, many of the timelines concern events that have happened in Asia, Australia, and other places globally. It...

Say a data set: a <- c(101,101,102,102,103,103) b <- c("M","M","P","P","M","M") dt <- as.data.frame(cbind(a,b)) dt a b 1 101 M 2 101 M 3 102 P 4 102 P 5 103 M 6 103 M Column a is subject_ID , and column b is subject_name . I want to uniquely rename subject ID 101 to M1, and 103 to M2. Is there a way to do this by indexing? This does not work. dt.try1 <- gsub("M","M1",dt[1:2,c(2)]) dt.try1 [1] "M1" "M1" This is what would be ideal result: a b 1 101 M 2 101 M 3 102 P 4 102 P 5 103 M2 6 103 M2 Why does not this work?

I am new to C programming language, and currently trying to add new syscall to Linux kernel by re-compiling the kernel. When I read the source code, I found it very difficult to locate the path of head file. For example: #include <linux/kernel.h> /* for printk */ #include <linux/syscalls.h> /* for SYSCALL_DEFINE1 macro */ SYSCALL_DEFINE1(printmsg, int, i) { printk(KERN_DEBUG "Hello! This is a msg %d", i); return 1; } This is one of my customized system calls. I edited the MakeFile in kernel/ folder and syscall_64.tbl . After re-compiling, it worked. No compiling error. However, my problem now is how the preprocessor resolves the path like <linux/syscalls.h> . Based on my previous understanding, the preprocessor would go to the folder /usr/include for searching. Certainly, there is no linux/syscalls.h within /usr/include . I found linux/syscalls.h is actually in linux's project include/linux/ . I was wondering what makes the pre...

Looking for a solution to properly annotate a subplot with an ordered pair of cartesian coordinates. My figure is a bar graph of total product quantities with a line graph of the average price for the given products. For additional reference, please see the figure at the end of this article: https://medium.com/swlh/product-sales-analysis-using-python-863b29026957 Please note, I have two vertical axes where: y1 = total quantity of a given product y2 = average price of a given product y1 & y2 share an x-axis of product categories Rather than plotting labels "(x, y)", my goal is to plot labels for (y1, y2), i.e. "(qty, price)". The current error that I am running into is that the list elements in my variable, label, are not recognized as "subscriptable objects". I am under the impression that the solution is to convert each element of my list into a string, but I am not positive. df = Products Quantity Price Product1 10 100.00 P...

I'm using optparse in a ruby program ( ruby 2.7.1p83 ) under Linux. If any of the command-line arguments are filenames with "special" characters in them, the parse! method fails with this error: invalid byte sequence in UTF-8 This is the code which fails ... parser = OptionParser.new { |opts| ... etc. ... } parser.parse! # error occurs here I know about the scrub method and other ways to do encoding in ruby. However, the place where the error occurs is in a library routine ( OptionParser#parse! ), and I have no control over how this library routine deals with strings. I could pre-process the command-line arguments and replace the special characters in these arguments with an acceptable encoding, but then, in the case where the argument is a file name, I will be unable to open that file later in the program, because the filename I have accepted into the program will have been altered from the file's original name. I could do something complicated like pre-...

My project is using JDK 8, Spring Boot 2.7.8 (I'm stuck with Java 8). I am successfully using Google OAuth2 for authentication. Users can log into and out of my site. They even have to authenticate to get to a /secure page and that works. However, when I try to incorporate role and/or authorities, I can only get HTTP 403 errors. I have a database with groups, users, group_members, etc, just like JdbcUserDetailsManager wants, and they're filled with data, as shown below. How can I get this to work?

I have a post route: (defroute admin-post ("/admin" :method :post) (&post client db email) (let ((c (write-to-string client)) (d (write-to-string db)) (res (by-email email))) (render-template* *admin.html* nil :title "Admin Area" :clientName c :dbName d :db-res res))) The value of email is processed by the by-email function successfully. But the c and d values are nil . ive also tried without write-to-string but it returns a blank value to the page. UPDATE Here is my html. The form names are the same as the defroute params: <form id="form" action="/admin" method="post"> <input type="text" name="client" placeholder="Enter Client Name"/> <input type="text" name="db" placeholder="Enter DB name"/> <input type="submit" value="Send"/> </form>

I am using Mockk and I have the need to intercept when an API client is being created. The API client does a bunch of REST stuff that I don't want to happen inside of its constructor. I have tried a bunch of things but can't seem to find a way to not actually run the constructor and just return something. I don't want to actually run anything when the object is created. Is this possible? I've tried: Class I want to mock: class TestApi(config) { auth = Auth.authenticate(config) // Don't want this specifically to run } Caller: fun createClient() { return TestApi(ConfigObj()) } Then in the test @Test fun `sample code`() { mockkConstructor(TestApi::class) every { anyConstructed<TestApi>() } returns FakeInstance() // other test stuff always fails as TestApi() still runs the full init with the auth flow }

My goal is to create a portable PDF that will execute with the portable navigator I include in the package. The problem is that the navigator's shortcut changes and sets itself relative path correctly, but the arguments on the target field (the PDF file I want the shortcut navigator to open when clicked) remains on the old path. The challenge is to get the argument path relative to wherever the shortcut is placed (both shortcut and folder with nav and PDF are moved together). I've tried to set a relative path on the argument in the target field to the Start in field, such as shown in the following example, but it won't work: Target-> E:\DATA\GoogleChromePortable.exe" .\myPDF.pdf Start in-> E:\DATA Both myPDF and myShortcut are placed in the same folder (DATA), and the Target and Start in fields become relative according to if changed, their paths adapt to the new location.

i have a "compensatable transaction" tx that is part of a choreography saga and was wondering how to deal with compensation when a bug is introduced in the system. It is clear that if there is a business requirement not fullfiled by tx an *FailedEvent must be emitted in order to start the compensation action chain, but should an event be published as a result of a failure (null pointer, out of memory, and so) ? In my opinion this should be treated as a bug, compensation is not fired and shuould be fixed with a manuall process. This forces me to add some generic error event in a global exception handler. Not sure about it.. Thanks

Based on the example of dataframe below, I would like to calculate difference between two datetime for certain index and its cumulative. The expected results are as in the column diff_days and cum_diff days index date_a date_b diff_days cum_diff_days 1 1/1/2023 NaT NaT - 1 NaT NaT NaT - 1 NaT 3/1/2023 2 2 2 4/1/2023 NaT NaT - 2 NaT NaT NaT - 2 NaT 6/1/2023 2 4 3 7/1/2023 NaT NaT - 3 NaT 8/1/2023 1 5 3 9/1/2023 NaT NaT - 3 NaT NaT NaT - 3 NaT 11/1/2023 2 7 I have checked the other post where it calculates the difference between two dates, unfortunately that one is when the date is in the same row. For my case, I wanted to understand how to calculate the dates if it's on different rows at different column since just subtracting it with df['diff_days'] = df['date_a'] - df['date_b'] will produce a NaT results.

I have a code that converts an image with 32 output layers, from an AI segmentation model output, into a single layer where each pixel in each layer has a probability proportional to its score to make to this single layer. In order to do that, I need to generate a random float number to figure out each of the 32 layers is going to be the winner. When I run this code in a single thread, it generates the same output every single time. However, when I use it with OMP (to make it faster), it generates a different output every time, even when I make the random number generator private to each thread and initialize it with the same seed (for each row). I also tried to hardcode the seed to 0 and it did not solve the problem. It is like one thread is interfering with the sequence of the numbers in the other one. I need this code to generate consistently the same result every time in order to make it easier to test the output. Any idea? cv::Mat prediction_map(aiPanoHeight, aiPanoWidth, C...

I am trying to update a sqlite3 database from a tkinter treeview. It should be relatively simple, but I am stuck My program consists of two files, one with the functions for the backend, the other with just the tkinter layout and its own functions for the app. The function in the backend file works fine and I have tested it: def update_book(book_id, book_title, book_author, book_qty): db = sqlite3.connect("bookstore.db") cursor = db.cursor() cursor.execute("""UPDATE books SET title = ?, author = ?, qty = ? WHERE id = ?""", (book_title, book_author, book_qty, book_id)) db.commit() db.close() This instead is the function from tkinter layout file, responsible to update the entry. At the moment it updates just the entry on the treeview, but NOT in the database. I tried to print the backed function (update_book()) to see the results, but it return None. I do not understand what am I doing wrong... By the way, 't...

I'm planning to create a cross platform (Windows, Linux, macOS, Android, iOS, Wasm) audio player using latest AvaloniaUI along with LibVLCSharp. Unfortunately only support for Windows, Linux and macOS is listed for Avalonia. I think that this might be a lack of documentation only, since Avalonia pretty recently introduced Android and iOS support officially. So how is the state of this? Would it be possible to create a REAL cross platform player for all the listed platforms with LibVLCSharp? And if not, is there an alternative, that could be used with AvaloniaUI? I found these libs for C#, that are (partially) capable of playing audio: LibVLCSharp (unmanaged/wrapper, cross platform including Android + iOS) SharpAudio (mostly managed, cross platform, but poor codec support atm) cscore (unmanaged/wrapper, well designed, development stalled) libsoundio-sharp (unmanaged, pretty raw) ManagedBass (unmanaged/wrapper for BASS, awesome but only free for open source) NAudio (awesome...
