            Null pointer check via "myPtr > 0"
            Asked 2022-Mar-30 at 01:04

            In some legacy code I came across the following null pointer check.



            Answered 2022-Mar-28 at 12:46

            Ordered comparison between a pointer and an integer is ill-formed in C++ (even when the integer is a null pointer constant such as it is in this case). The risk is that compilers are allowed to, and do, refuse to compile such code.

            You can rewrite it as either of these:



            Is Rust trait the same as Java interface
            Asked 2022-Mar-11 at 05:06

            It looks to me that Rust's trait is the same thing as Java's interface - a set of functions that needs to be implemented on object.

            Is there a technical reason for naming it trait not interface or is it just some preference?



            Answered 2022-Mar-11 at 05:06

            Interface is a concept of Object Oriented Programming. When you say that an object type implements an interface, you are talking about a property of that type. It says that the type follows certain contract.

            Rust is not an object oriented language. And traits are not exactly interfaces. When you say, that a struct has some trait, it does not necessarily mean, that it is a property of the struct, but rather that struct maps with the functionality of the trait.

            For example, you can have a built-in rust type [f32; 2] - an array with two values. And you can have a trait Point:

            How can I convert a String into a Char list?
            Asked 2022-Jan-03 at 16:58

            I am trying to write a program that removes a specific element from a string, but most of the things I use (like filter) only work for [Char]. I really just don't want to have to type "['h','e','l','l','o']" instead of "hello". I realize that technically a String is just a fancy [Char], but how would I unfancify it into a standard [Char]. Also if you have another way to write normal words instead of in an array format please tell me.



            Answered 2022-Jan-03 at 12:31

            In Haskell, the square brackets mean a list, as they also do in Python. Haskell also uses white space syntax.

            You can tell what type a String is in Haskell by using :t in the ghci REPL.



            In C#, why can't I populate a local variable using its address, then use the variable later?
            Asked 2021-Dec-09 at 05:14

            Consider the following code:



            Answered 2021-Dec-08 at 13:39

            The C# specification says the following (my bold):

            23.4 Fixed and moveable variables

            The address-of operator (§23.6.5) and the fixed statement (§23.7) divide variables into two categories:
            Fixed variables and moveable variables.


            The & operator (§23.6.5) permits the address of a fixed variable to be obtained without restrictions. However, because a moveable variable is subject to relocation or disposal by the garbage collector, the address of a moveable variable can only be obtained using a fixed statement (§23.7), and that address remains valid only for the duration of that fixed statement.

            In precise terms, a fixed variable is one of the following:

            • A variable resulting from a simple-name (§12.7.3) that refers to a local variable, value parameter, or parameter array, unless the variable is captured by an anonymous function (§
            • .....

            So it's explicitly forbidden by the spec. As to why it's forbidden, for that you would have to ask the language designers, but considering how much complexity is involved in capturing variables, it is somewhat logical.



            How to detect windows 11 from user agent?
            Asked 2021-Nov-23 at 18:30

            How I can figure out if someone opens my website in windows 11?

            I test user agent and when someone opens my website with windows 11 I will get this

            "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:91.0) Gecko/20100101 Firefox/91.0"

            So technically this says it's windows 10, not 11.

            Is there any way to detect this?



            Answered 2021-Aug-15 at 21:24

            Well, capped the Windows version at 10 for Firefox, so that's really not going to work for you...



            Kotlin - Check collection contains another collection exactly
            Asked 2021-Nov-22 at 14:42

            I want to be able to check that collection a contains exactly all of the elements of b, but an equality based check is not sufficient; for example:



            Answered 2021-Nov-22 at 13:57

            One way I can think of is to make a mutable copy of a, and try to remove every element of b, then check if all elements of b can be removed:



            Google PlayStore Hotfixing a previous Release, while in staged rollout
            Asked 2021-Nov-17 at 07:46

            We plan an unusual deployment sequence of an App into the Google Playstore.

            Setup: We did rollout a Version V1.0 and afterwards a V2.0 to all customers into US and UK. We did a breaking change in the backends in US. And did a staged rollout of V2.5 into US. V2.5 does not work in UK, but we are on it to have it soon. Now we have an incident in UK, requiring an Hotfix release V2.0.1 there.

            Goal: UK Customers do get a V2.0.1. while US Customers keep their V2.5 version.

            We tried:

            • Rolling out 2.0.1 in UK only. This disabled V2.5 for US and US customers received V1.0 (because V2.0.1 is only rollout in UK, and V2.5 was overridden by V2.0.1)

            Next idea:

            1. Rolling out V2.0.1 to UK and US for every customer
            2. Wait for approval by Google PlayStore
            3. Immediately after approval, rollout V2.5 for US again

            Question: Will above idea work? Technically the rollout is setup in the store. And this is the way any hotfix, will work, right? But practically does every UK customer get the V2.0.1, while the staged V2.5 US only rollout runs too. The other risk is, that the approval of the V2.5 US rollout can take some days.



            Answered 2021-Nov-17 at 07:46

            We could contact a Google Consultant. After some weeks of back and forth, we got confirmation from a Google technical team about it. And they confirmed, that we can do our plan as described in the question. It will work.

            We can do a full rollout to all countries, afterwards a staged rollout to selected countries affecting 100% of those users, and later we can add the missing countries, and the rollout becomes full release.



            What's the point of a deep folder structure in Java (Maven)?
            Asked 2021-Nov-16 at 14:53

            I've inherited a Java (Maven) project at work. I'm not a Java developer, but the project is now mine, nonetheless. When I clone (a la git clone) the repository, I notice the folder structure goes really deep before any .java files appear. For instance, the folder structure looks like this:



            Answered 2021-Oct-19 at 21:40

            Maven is a tool that has certain opinions on where things should go; a default configuration. You don't have to follow it, but not following this default configuration has three significant downsides:

            • You do have to then configure maven to tell it about the alternative choices you made. Maven does not make this easy.
            • Other java programmers generally assume the defaults. If you have a good reason to deviate, go for it, but 'I do not like it' is not a good reason, as it'll be pointlessly increasing the learning curve.
            • The maven developers chose this structure as default for a reason. If you think it's a dumb reason, that's certainly possible and you may even be right, but then you're using a build tool written by folks who, (judging the book by its cover a little bit), according to you, make boneheaded choices about sane defaults. That's not a great place to be.

            To explain each layer:


            Indicates that these are source files: Compiled and generated stuff should not be in here, and the entire src tree should be in version control. Contrast to e.g. bin or build containing build artefacts, doc containing documentation, and who knows what other directories you need for other relevant parts of a repo.


            A project can consist of multiple separately buildable artefacts and 'kinds' of product. For example, most projects include a bunch of code that exists solely for testing purposes (the unit tests). They live in src/test. The core product lives in main. You can also have for example separate sources for an installer perhaps (src/installer), or a build plugin, or an annotation processor that needs to be built first and then it needs to be on classpath when compiling the main project, etcetera.


            There's such a thing as split language projects, where some of it is written in language A and some of it in language B. For its worth, I think this layer is bad design; A file ending in .java gives away how one is to 'compile it', and this goes for just about every source file that needs a compiler applied to it: The extension says just as much as a folder name of java ever could. To show you a common contrast: Many projects have src/main/resources as well as src/main/java: Resources are 'compiled' simply by copying them over: Imagine your app has a text file containing a list of all US states with all zipcodes used in each state. Or png files with icon images for a GUI app. Such files are just as much part of your main application as the class files would be and should end up in the same place (inside the jar file), but to 'compile' them, you just.. copy em, you don't run javac to do this. That's what this level is about: What tool should be used to turn source files into distributable aspects?


            This matches the java package structure. This is effectively a requirement applied by javac itself. The reason to use such a deeply nested package structure is simply because packages serve as namespaces: If there is a conflicting fully qualified name, all hell breaks loose: Java simply cannot handle this. Hence, java programmers ensure that such conflicts never happen by using a 'reverse domain name' structure: You'd stick your project in that package if you own the domain, thus ensuring nobody except other folks in your team who share control of that server could possibly be in conflict (and for those: They're in your team, talk to them to avoid conflict). For example, there are 3 different open source java projects all called spark. Had they all gone with package spark; (and thus, src/main/java/spark/ as an example file), then for every java project you'd pick one of the 3: The other 2 you can never use in this project. Harsh, and pointless, which is why (almost) all java libraries use a reversed domain name as root package name, and then maven follows this package name in its directory structure because javac makes life extremely difficult if you don't do that.

            That gets us to project_name/src/main/java.


            You made that up for hyperbole. Nobody hosts a proj on But if they do: Talk to the management that decided to assign that whopper of a domain name to a team. It's on them, not on the author of this project.
