"Single endpoint post array with multiple type of dictionary",
"I am creating the RESTful endpoints for supporting frontend payload.\nMy payload is an order of build your own dish and ready-made single dish\n\nProblem:\nIn single POST of frontend. He wants to put everything to the single time. That's mean in the given list will contains 2 types of dictionary\none for build your own and one for ready-made single dish\n\nIMO:\nHe can POST 2 times for each type of payload. By this method the endpoint will do one thing and I prefer that way.\n\nHe has only 1 reason to POST everything to single endpoint\n\nQuestion:\nWhat is your best practice for this sort of problem?\n\nBuild Your Own Payload:\nIn short I call it BYO.\n1. base_bowl will dictates the size and price of the item\n1. base_bowl will also determine the number of fishes, toppings, sauces. \nBecause base_bowl size S, M, or L has different quota. \n\nFor example \n\nSize S can has fishes 1 scoop size S, and toppings 2 scoops size S.\n\nSize M can has fishes 2 scoops size M, and toppings 3 scoops size M. Then if the customer would like to add more than quota he must add it in the extra_fishes, extra_toppings\nBase on Price id since quantity is determine by number of member in the list.\n\n {\n \"base_bowl\": salad.id, # require=True, Price id\n \"fishes\": [salmon.id, tuna.id],\n \"extra_fishes\": [tofu.id],\n \"toppings\": [tamago.id, mango.id],\n \"extra_toppings\": [rambutan.id],\n \"premium_toppings\": [ikura.id],\n \"sauces\": [shoyu.id, spicy_kimchi.id],\n \"extra_sauces\": [],\n \"sprinkles\": [sesame.id, fried_shalots.id],\n \"dish_order\": 1, # require=True\n \"note\": {\n 'msg': 'eat here',\n },\n }\n\n\nAnd backend will validate the input and INSERT them to Order and OrderItem\n\nReady-Made Dish:\nThis is very straight forward because it has no implicit logic like BYO. It just add OrderItem to Order\n\nUse Menu id, size, and qty to determine price. Because customer is free to choose\n\n{\n 'order_items': [\n {\n 'menu_id': has_poink_menu.id,\n 'size': Price.MenuSize.XL, # 27, 37, 47, 52\n 'qty': 2, # amount = 52 * 2\n },\n {\n 'menu_id': no_poink_menu.id,\n 'size': Price.MenuSize.L, # 20, 30, 40, 45\n 'qty': 1 # amount = 40 * 1\n }\n ]\n}"

"Is there any way to prevent getaddrinfo from revealing the true IP address of a hostname?",
"Let's say there is a program that opens up the HOSTS file to make sure that it isn't being rerouted somewhere. (It wants to connect to www.example.com but it makes sure you don't have an entry in the HOSTS file for that).\n\nSo instead, you decide to add a DNS entry, so that www.example.com really points to 123.123.1.123. So that works.\n\nBut then the program gets smarter and calls getaddrinfo to determine if it's being rerouted to 123.123.1.123. Is there any way to hide this information, or any alternate ways of changing the IP Address of a given hostname?\n\nIs there any way to make the normal IP of www.example.com point to 123.123.1.123?\n\nAll I can think of is maybe detours, but I'm wondering if there's a better way. Perhaps there is a way to protect the Windows HOSTS file from being read?\n\nOr is there a way to spoof packets so that it appears that they come from \"www.example.com\"?

"Objective-C vs. C speed",
"This is probably a naive question here but I'll ask it anyway.\n\nI'm working with Core Audio (C API) on iOS and am mixing C with Objective-C. My class has the .mm extension and everything is working so far.\n\nI've read in different places about Objective-C being slow (without much detail given - and I am not making any declaration that it is). I understand about not calling Objective-C from a Core Audio render callback, etc. and the reasons why.\n\nOn the other hand, I need to call in to the class that handles the Core Audio stuff from my GUI in order to make various adjustments at runtime. There would be some walking of arrays, mostly, shifting data around that is used by Core Audio. Would there be any benefit speed-wise from writing my functions in C and storing my variables in, say, vectors rather than NSMutableArrays?\n\nI've only been working with Objective-C/iOS for a few months so I don't have any perspective on this."

Now it comes to validation. I added @Assert annotations for both entities in their respective files.

"Find application installation path from UpgradeCode",
"I'm faced with little \"inconvenience\" using Visual Studio 2010 setup and deployment projects. Let's say I have 2 applications: App1 and App2. Both applications have separate MSi installation packages and can be installed to different locations. App1 need to know where App2 is installed. Previously I was provide App1 with \"ProductCode\" value of installation package of App2. This way App1 could find installation path of App2 looking for appropriate value in \"ProductCode\" key in the HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Uninstall.\n\nNow I was updated the version of App2 installation package and Visual Studio urged me to change the ProductCode. It was changed and now App1 can't successfully use previous ProductCode to find installation path of App2. Of corse I can give new ProductCode to the App1 but I will be forced to do this each time when App2 version updated. Also old version of App1 will be unable to find new version of App2 because new ProductCode will be unknown for it.\n\nSo I need more \"persistent\" method to find App2 installation path. I think of UpgradeCode value of Visual Studio setup and deployment project which is never changes unless developer will change it himself for some reason. But I couldn't find any trails of UpgradeCode in the registry.\n\nIs anyone know where UpgradeCodes are saved? Or probably the way to find actual ProductCode when we know UpgradeCode exist? Maybe someone have a better method of finding installation paths of applications?\nThanks in advance."

"I am trying to write an application to track legal case requests. The main model is Case, which has_many Subjects, Keywords, Notes, and Evidences (which, in turn, has_many CustodyLogs). Since the application is legal-related, there are some requirements that are out of the ordinary:\n\n\nCRUD operations must be logged, including what the operation was, who the actor was, and when the operation occurred\nThere needs to be some way to validate the data (i.e. recording MD5 checksums of records)\nSome data should be write-once (i.e. the app can create an audit log entry, but that log cannot be edited or deleted from within the application thereafter)\nChanges to associated objects probably should be logged throughout the nesting. For example, adding a CustodyLog to a piece of Evidence should have a log for itself, a log for it's Evidence, and a log for the parent Case. This is to ensure that the last update timestamp for the Case accurately reflects the real last update, and not just the last time that the Case model data itself changed.\n\n\nI've got bits of this working, but I'm running into a problem. Authentication is being handled by an external web single-sign-on service, so the only visibility to the ID of the logged in user is in a request variable. If I put audit logging in the model, through a callback, for example, I can be fairly sure that all data modifications are logged, but the model has no visibility to the request variables, so I can't log the user ID. This also ensures that changes to the state machine (currently using state_machine plugin) get logged.\n\nIf, on the other hand, I put the audit logging in the application controller, I lose the ability to be sure that all CRUD operations are logged (code in the Case model calling Subject.create, for example, wouldn't be logged). I also think that I'd lose state changes.\n\nIs there a way to be sure that all CRUD operations are logged throughout the association tree such that the user ID of the logged in user is recorded?"

"G++ Multi-platform memory leak detection tool",
"Does anyone know where I can find a memory memory leak detection tool for C++ which can be either run in a command line or as an Eclipse plug-in in Windows and Linux. I would like it to be easy to use. Preferably one that doesn't overwrite new(), delete(), malloc() or free(). Something like GDB if its gonna be in the command line, but I don't remember that being used for detecting memory leaks. If there is a unit testing framework which does this automatically, that would be great.\n\nThis question is similar to other questions (such as Memory leak detection under Windows for GNU C/C++ ) however I feel it is different because those ask for windows specific solutions or have solutions which I would rather avoid. I feel I am looking for something a bit more specific here. Suggestions don't have to fulfill all requirements, but as many as possible would be nice.\n\nThanks.\n\nEDIT: Since this has come up, by \"overwrite\" I mean anything which requires me to #include a library or which otherwise changes how C++ compiles my code, if it does this at run time so that running the code in a different environment won't affect anything that would be great. Also, unfortunately, I don't have a Mac, so any suggestions for that are unhelpful, but thank you for trying. My desktop runs Windows (I have Linux installed but my dual monitors don't work with it) and I'd rather not run Linux in a VM, although that is certainly an option. My laptop runs Linux, so I can use that tool on there, although I would definitely prefer sticking to my desktop as the screen space is excellent for keeping all of the design documentation and requirements in view without having to move too much around on the desktop.\n\nNOTE: While I may try answers, I won't mark one as accepted until I have tried the suggestion and it is satisfactory.\n\nEDIT2: I'm not worried about the cross-platform compatibility of my code, it's a command line application using just the C++ libraries."

"Creating a Constraint as a Trigger in phpMyAdmin",
"So I've seen plenty of trigger examples in phpMyAdmin, but the syntax isn't making sense to me... I'm way oversimplifying it.\n\nI want to create a constraint on phpMyAdmin. I have two tables, one is Funds, and one is Fund_Shares_Purchased. In Funds, there is an attribute \"total_available\", which is the total number of shares that can be purchased. In Fund_Shares_Purchased, there is an attribute \"quantity\", which is how many shares somebody has bought. The two tables are related on the \"Fund_Name\" attribute.\n\nI tried the following...\n\nCREATE TRIGGER limitFundShares\nBEFORE INSERT ON Fund_Shares_Purchased\nBEGIN\n IF (Fund.total_shares < NEW.quantity)\n THEN\n RAISERROR(\"You can't buy that many shares of the fund!\")\n END IF;\nEND;\n\n\nAny help or guidance would be much appreciated!"

"Why can a full property in C# be overridden with only a getter but it can still be set?",

Given the following two classes:\n\nclass Parent\n{\n public virtual bool Property { get; set; }\n}\n\nclass Child : Parent\n{\n public override bool Property { get => base.Property; }\n}\n\n\nI can write code like this:\n\nChild child = new Child();\nchild.Property = true; // this is allowed\n\n\nThe IDE makes it confusing, too, because, while it allows the assignment, it also indicates that the overridden property is read-only:\n\n\n\nFurthermore, this override is only allowed when I'm using the base class' getter:\n\n\n\nWhat is going on here?"

"statvfs() returns a filesystem ID of 0 for tmpfs; is f_fsid trustworthy?",
"I'm writing a sanity-check C routine that runs through a list of certain paths and checks whether the free space in each of them is above a certain threshold. In order to not make unnecessary checks if many of these paths are in the same filesystem, I had the idea of checking the f_fsid member of the statvfs structure filled by statvfs(). It does work, but when I check /tmp I see the f_fsid value it returned is zero. This is Ubuntu 20.04, in which /tmp is mounted as tmpfs.\nNow I'm starting to worry yet another funky filesystem type might not return a usable f_fsid and my logic will make me skip a check I should make. Is there a more trustworthy way for a C program to check whether two paths are in the same filesystem? Or should I stop worrying since it works OK for real-storage type fs's as it is?"

"Consider the following example:\n\nx = magic(3);\nfigure(1); clf(1);\nplot( x, '-r', 'DisplayName', 'Magic' );\nlegend( 'show' );\n\n\nThe resulting legend entries in MATLAB R2014a are\ngetcolumn(Magic,1)\ngetcolumn(Magic,2)\ngetcolumn(Magic,3)\n\nThe problem stems from function [leg,labelhandles,outH,outM] = legend(varargin) in legend.m (Copyright 1984-2012 The MathWorks, Inc.), line 628:\nstr{k} = get(ch(k),'DisplayName');\nMore specifically, the function get\n\n\nprepends getcolumn( and\nappends , <Column Number>).\n\n\nIs there an easy way to display exactly one legend entry (or multiple, but without the pre- and appended strings) for multiple data rows named after DisplayName, which have the same visual properties? \n\nAn alternative would of course be to programatically create multiple (or one) legend entries through plot handles (see below), but I would like to keep things short and simple.\n\nOne entry:\n\nx = magic(3);\nfigure(1); clf(1);\nh = plot( x, '-r' );\nlegend( h(1), 'Magic' );\n\n\nMultiple entries:\n\nx = magic(3);\nfigure(1); clf(1);\nh = plot( x, '-r' );\nstrL = cell( 1, numel(h) );\nfor k = 1:numel(h)\n strL{k} = sprintf( 'Magic %d', k );\nend\nlegend( h, strL );\n\n\n\n\nIn MATLAB R2014b, the problem with getcolumn(Name,Row) does not appear anymore for the first code example."

"ConstraintLayout alignment with offset",
"I am using a ConstraintLayout with two views inside. An ImageView that varies in size depending on the image loaded and a View which acts as a custom made dropshadow for the Image. What I've been doing so far is adding 8dp padding to the ImageView and then aligning all of the edges of the View to the ImageViews, thereby making the View stick out 8dp underneath the ImageView. \n\nNow for several reasons I don't want to keep the padding on the ImageView but I still want to achieve the same effect. So basically I would like to align the Left of the View to 8dp left of the Left of the ImageView (and the same for every other edge, right, top, bottom).\n\nIs there any way to achieve this?\n\nThanks in advance!"

"Does Jekyll support backticks code blocks now?",
"When I read the official documentation, it only mentioned the {% highlight python %} syntax:\nhttps://jekyllrb.com/docs/templates/\n\nHowever I prefer to use the backticks code block to highlight codes in markdowns:\n\n```python\n code goes here\n```\n\n\nI googled around and found a few requests but I'm not sure if the backticks work right now. If it works, how can I enable it? As I experimented with my own jekyll github page and it still only works with {% highlight python %}.\n\n\n\nIt seems that the kramdown is only on Jekyll 3.X. Unfortunately, the theme that I'm using is on 2.X.\n\nhttps://cecilialee.github.io/\n\nHow can I work on it? Would I be able to update my theme to Jekyll 3.X without breaking anything? Or how can I add the function to my current Jekyll site?"
