The hard part is figuring out exactly how your code needs to adapt to changes in the JSON structure. In your example, presumably the rest of your program needs to depend on the names and types in p...
It appears that the tuple syntax works like this: (variable index, order of derivative) Where something like: base = poly(x*y**2 + x, x, y) deriv_mysterious5 = base.diff((0,1)) print('deriv_mysteri...
I assume the built-in definition you're referring to is pmat. That illustrates how to solve your problem near the bottom. The idea is simply if σ is a permutation of length N and A is an array of l...
This is happening because of assumptions made by the software. "E notation" is a standard convention popular with scientists, mathematicians and engineers as a convenient way to represent and proce...
I have some SQL scripts that contain DDL to create tables and schemas for a database. I'd like to be able to comment this SQL and then use those comments to generate output documentation (in HTML)...
There is a new page What type of questions can I ask here? (found under Help -> Guidance.) I'll quote it as whole below, for convenience. Please give feedback on specific items in the list that ...
On-topic questions about SQL programming ... Off-topic questions about database administration I propose that these two are changed to clarify that we allow questions about database design an...
I propose that the following is added: On-topic questions asking for code review that follow [the site policies for the code review category]. Where [the site policies for code reviews] is a li...
In short, NULL is the 0 value, and a null pointer is a pointer variable that points to nothing. some systems allowing a different representation of the null pointer other than zero Years back...
I am working at a proof-of-concept for porting an ASP.NET MVC application to an ASP.NET Core API + Angular SPA. One of the features of the existing application is the ability of an admin (typically...
I can't get a response from IPv4 dig on my server but I can get one from IPv6 dig. See the below output: $ dig +short myip.opendns.com a @resolver1.opendns.com # Doesn't return anything, this used ...
Based on the source code which delegates to this implementation among others, base.diff((x, n)) means to compute the n-th derivative of base with respect to x. Any arguments to diff which aren't tu...
I am planning to build a "Customer Management Portal" as a hobby project using technologies like HTML,CSS,JavaScript,JAVA,JDBC,Oracle Database.The description of the portal is: 1)Customer details ...
There are a lot of factors that can go in the choice of a language: Do the properties of the language itself meet your requirements (e.g., C allows for more low-level optimizations than Visual ...
How do I create a flag that can be used multiple times in a command using the pflag package? For example, let's say I wanted to select multiple fields and did not want to have to use comma-separati...
I suspect this is an outdated practice: Prior to npm 3, npm did not keep track of resolved dependencies, and npm install would try to reconcile the existing with the declared dependencies. Since no...
I'm using Doxygen to help me figure out some library code. There's an enum I know I need to use, but I don't know which file it's declared in. Searching for that identifier in Doxygen yields the p...
I was wondering if the comment box can be altered? So the text-area can be expanded/re-sized? It's quite frustrating to get to the right text scrolling in such small box whilst it's not interactiv...
I am currently making an esoteric language which requires a theoretically infinite canvas. Basically, it should be able to resize and fit the contents of the drawing in and outside it's existing bo...
Yes, this is supported by the flag definition functions with Array or Slice in their names. See the reference docs for pflag. A simple example below: package main import ( "fmt" ...
I'm new to type_traits and #2 made sense right away. Everything else was confusing, but I don't know a good way to avoid #4. Maybe you even need #1 sometimes. #1 : enable_if on the return type Wh...
Problem I'm trying to update some projects from old-style .csproj: <?xml version="1.0" encoding="utf-8"?> <Project ToolsVersion="14.0" DefaultTargets="Build" xmlns="http://schemas.mi...
Consider the following code: public class OnlineShoppingService { @Transactional public void cancelOrder(String id) { if (shipmentRepository.findShipmentForOrder(id) != null) { ...
I am interested in a guideline to understand how dependencies are considered when building the healthcheck functionality for an API. Like any functionality, the implementation of this feature sho...
Adding to Peter Taylor's reply: The OP requested something "more LINQ". I guess it can't get any "more linq" than... MoreLINQ! That library also has a ForEach(). If you only need that, maybe it...
