I am working on an address book that is a single page javascript application. It uses a custom router function which renders different views based on the url. The url is always divided into the root which is the domain name and separated by a forward slash, hash, and another forward slash (ex: localhost:3000/#/...) followed by the fragment where the fragment contains the rest of the identifier information needed for the router function to show the right view (ex: localhost:3000/#/contact/contact_id=1&name=John+Doe) would show the contact page for contact 1, John Doe. The application has a side panel that allows the user to click an icon to navigate to four higher level views as well as to a page to create a new contact. Navigating through the side panel icons using the browser's back/forward buttons is working perfectly. The application organizes contacts into a few different types of lists. Once the user finds their way to a contact's page they can click a button on the

Please help me solve the problem. Due to the large number of point light sources, there is a problem with textures and incorrect display of shadows on textures. Since many rooms are located behind the same wall and need to be illuminated, it is not possible to reduce the number of light sources (at least I do not know how to do this). https://youtu.be/YOTth6ZDbgg enter image description here enter image description here enter image description here enter image description here

I'm using the table model of Apache IoTDB 2.0.6 to implement a data filtering feature, where I need to mark whether each record belongs to a specific category. For example, I want to check if each product's price is in the price list of "Category A" products. Raw Data CREATE TABLE products (product_id STRING Tag, category STRING Tag, price INT32 Field); INSERT INTO products(`time`, product_id, category, price) VALUES (2024-09-24T14:00:00.000+08:00, 'p01', 'A', 100); INSERT INTO products(`time`, product_id, category, price) VALUES (2024-09-24T14:01:00.000+08:00, 'p01', 'A', 200); INSERT INTO products(`time`, product_id, category, price) VALUES (2024-09-24T14:02:00.000+08:00, 'p01', 'A', `NULL`); INSERT INTO products(`time`, product_id, category, price) VALUES (2024-09-24T14:03:00.000+08:00, 'p02', 'B', 150);

RARS 1.6 – HEX Keypad + Bitmap Display Problem I am using RARS 1.6 with: Digital Lab Sim (HEX Keypad) Bitmap Display Polling-based keypad scanning Assignment Requirement Create a 4×4 grid on the Bitmap Display. Each key on the HEX keypad corresponds to one cell in the grid. When a key is pressed, the corresponding cell should turn red. All other cells should remain black. Example mapping: 0 1 2 3 4 5 6 7 8 9 A B C D E F The bitmap size is 256×256, so each cell is 64×64 pixels. Current Problems Problem 1: Program only works at MAX speed The program only reacts to keypad input when I set Run Speed to MAX in RARS. If I lower the speed (for example 30 inst/sec or 300 inst/sec): keypad input stops working or becomes

What rule can be consistently used to identify the item(s)/element(s) which will be repeated in the next bracket. It is noted that on rare occasions there is no repeat in the next bracket and also that in the last part of the data there are a lot of double repeats in the next bracket. Hence the rule should (a) Indicate which item will be repeated in the next bracket (b) State clearly what condition(s) lead to no repeat in the next bracket; and (c) What condition(s) lead to double repeats in the next bracket. The rule should consistently apply to all the repeats (single, double, etc.)/no repeats in the data provided below. The dataset is alphanumeric: {0A 0B 0C 1A 1B 1C 2A 2B 2C 3A 3B 3C 4A 4B 4C 5A 5B 5C} [1C 0B 3B 2A 5A 3A]; [1A 0B 3B 2B 4A]; [1A 5C 2A]; [0C 5A 3A 1A 2B]; [2A 5C 4A 1A]; [1A 5B 4B 3A]; [1A 2B 4C 5A]; [2B 0A 4A 1B 3A]; [5B 4A 1B 3C 2A]; [3A 4B 5C 2A]; [2C 5C 1A 4C]; [5C 3A 4A 0B 1A]; [5C 4B 2A]; [0C 5B 4B 1A

I have a function that has both Windows and Linux code in it. Due to the fact that I'm using execl, there's a point where some code will be unreachable. Is there a C++ attribute for this? uint32_t Verify(const std::string& exe_path, const std::string& file_path) { #ifdef _WIN32 // Windows code is here return 0; #else if (pid_t pid = fork(); pid == -1) return 1; else if (!pid) execl(AppData::RAR_PATH, std::filesystem::path(AppData::RAR_PATH).filename().c_str(), std::format(AppData::RAR_CMD_LINUX, file_path).c_str(), (char*)0); else { int status{}; waitpid(pid, &status, 0); return WIFEXITED(status) ? 1 : 0; } #endif } I'm handling all cases, but the compiler still says that it will reach the end of a non-void function. I could just remove the else block entirely, but I'm interested in attributes. I have tried [[unreachable]] and [[noreturn]]

Using TypeScript v6.0.3 (also tested on earlier versions down to v4.9.5), I'm narrowing the type for the options of a function which are passed as an object. Some of those parameters have default values. The parameters which have default values aren't working properly with TypeScript automatic type discernment, as far as I can tell. Why does fun1 fail to narrow the type of t in the if block, yet fun2 can properly narrow its type based on the definition? Is this a bug? type Type = { b?: false, t: number, } | { b: true, t: string, } // This doesn't work function fun1({b = true, t}: Type) { if(b) { t /* <-- can't discern type as 'string' only, is 'string|number' */ } } // This works function fun2({b, t}: Type) { if(b) { t /* <-- can discern type as 'string' */ } }

I am currently coding a Kernel, i am trying to use debug msg to check if the kernel has an error. But for an unknown reason, my debug msg is not printed on the screen, I tried Here the main code of the kernel : kernel_entry: cli mov ax, 0x1000 mov ds, ax mov es, ax mov fs, ax mov gs, ax mov si, DEBUG_MSG call print_string mov ax, 0x1000 mov ss, ax mov sp, 0x9000 mov si, DEBUG_MSG call print_string call load_memory_map mov si, DEBUG_MSG call print_string jmp $ print_string: .next_char: mov al, [si] cmp al, 0 je .done mov ah, 0x0E int 0x10 inc si jmp .next_char .done: ret DEBUG_MSG db "debug", 13, 10, 0 I'm not using grub since i use my own bootloader in assembly, if you need it : start: push cs pop ds mov si, boot_title call print_string mov si, option_1 call print_string

What is the recommended way to replace rimraf in a deno project and in particular in deno tasks? The project [https://github.com/franckLdx/fs_cli] was aiming to fix this but it is outdated. Chatgpt recommends to write some ts-file for deleting the files but that's over-engineered for such trivial task. So do we have some deno-based cli to delete files and directories? Or should we create it? rm -fr would be a not multi-platform workaround.
