monster is a Rust library. monster has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

Monster is an incomplete symbolic execution engine for 64-bit RISC-U binaries generated by Selfie. It can find bugs like division by zero of an unknown binary. It's incompleteness is used as an advantage, by using an shortest path exploration strategy based on the binary code structure, to prune the state search space optimistically. In the backend an incomplete SMT solver is implemented, which further boosts performance. Popular SMT solvers like Boolector and Z3 are also supported as an optional build option.

            UML class diagram for domain with movies
            Asked 2021-Jun-15 at 11:58

            I am currently creating class diagrams in UML for a movie test domain. I would like to know if I am doing it right. Well, I have two alternatives (the first version in the first picture, the second in the second - I think the first one is better). I'm wondering if I've established the so-called "relationship owner" correctly, that is, from which class to which direction the relationships go. I also don't know if I didn't get multiplicity wrong (one to one, one to many etc.).

            So on my domain I would like to have movies of course, the actors starring in those movies and directors. I wonder if the class name "Character" is good in this case, because I mean all the characters that take part in a movie - it can be director, actor but also for example "Batman". Maybe I should make a distinction here between "Movie Character" and then "Human", "Monster", whatever. But I don't know how to do it elegantly, will I then inherit from the Character class? I'm also wondering if I shouldn't put classes like City or Country together in one class called Address - but I wanted the classes to take attributes like in this case, that one is Master and the other is detail - and the relationship set in the right direction. I use only relations such as Inheritance and Dependency, I do not know if I should change something in this case.

            Version 1

            Version 2

            Thanks in advance for any suggestions or advice!

            In short

            Use inheritance very carefully. Prefer association over inheritance whenever your inheritance is not a permanent truth from the birth to the death of an object. ANd keep in mind that dependencies between classes do not make any promises about objects of those classes.

            Some more explanations

            Some clarifications on the UML syntax:

            • I understand that your plain thick lines ended with a small hollow triangle represent a specialization/generalization relationship (aka inheritance). If this is correct, the triangle should be larger to avoid visual confusion. Moreover multiplicity makes no sense with inheritance and should be removed.
            • I understand that with the dotted line you intend to represent an association with multiplicity. If this is correct:
              • the association should be plain lines, because dotted lines are for dependencies, and multiplicity would make no sense.
              • the meaning you give to the arrow head would be unclear. Do you use them to document navigability? In case of doubt, remove them. If you want to document ownership of the association end, use the dot notation instead. (we cannot say if it’s right or wrong, since it’s a decision on how your model sees the associations)

            In view of your comments and the third model linked therein, there are some key UML semantics you need to keep in mind:

            • Inheritance is an ultra-strong relationship which means "is (always) a". In your example, you may say that an Actor is always a Person, and hence, everything you say about a Person is also true for an Actor. By the way, you should avoid repeating inherited properties or methods, since it could create some ambiguity.
            • Inheritance is not a substitute for aggregation, composition or association. You can for example not say that a CrewMember (one person) is always a Crew (a group of persons). A CrewMember belongs to a Crew but there are things that the crew can do together that the individual member can't.
            • Inheritance is not suitable if it's not always true. A Character for example may often be a Person. But not always;: you can have ghost characters, comic characters, robot characters, or animals.
            • Association means that there is some structural relation between some instances of the associated classes. For example, that one ore several persons live in one city, seems a very relevant assocaition.
            • Dependency means that a class is dependent on another, i.e. without the other class it would not work or something would be missing. It's a statement about the classes and not the objects. I.e. If you meant to say that Person is dependent on City you just say that the class Person would not work without knowing about City (for example, because the operation sendPostCardFrom(city: City) needs an argument of that type) but you do not say anything about persons X, Y and Z. If you want that X, Y and Z are related to city a, b, and c, you need an association.

            About the model content, I'll not decide for you and there is no single truth. I therefore prefer to draw your attention at potential issues. I raise them in form of a question, up-to you to adjust the model based on your own answer:

            • Common issues between the both variants:

              • Are Actor and Director really Persons ? In this case, what with the Persons that are Actors and Directors at the same time (g.g. Clint Eastwood) ? Or are Actor and Director just roles that a Persons takes for a given Movie ?
              • Is a Character really related only to 1 Movie? What to do with Indiana Jones, where the same character appears in several movies?
              • In a similar way, I wonder if there's really a single Person who lives in a City or if this should not be a many-to-many association?
            • Issues regarding the differences: `

              • Is a Person in version 1 a Character (inheritance) ? Or is a Character a representation of a Person (association: represents) ?
              • Is a Character in version 2 really an Actor and by transitivity also a Person (inheritance)? Or is the Character only associated with an Actor (association: plays) ?

            It's up to you to decide, but wherever I asked a question about association or inheritance, you should better think twice before using inheritance (i.e. prefer association/composition over inheritance)

            Why Do I Keep Receiving an Access Violation Exception?
            Asked 2021-Jun-13 at 00:59

            I am currently on the path of learning C++ and this is an example program I wrote for the course I'm taking. I know that there are things in here that probably makes your skin crawl if you're experienced in C/C++, heck the program isn't even finished, but I mainly need to know why I keep receiving this error after I enter my name: Exception thrown at 0x79FE395E (vcruntime140d.dll) in Learn.exe: 0xC0000005: Access violation reading location 0xCCCCCCCC. I know there is something wrong with the constructors and initializations of the member variables of the classes but I cannot pinpoint the problem, even with the debugger. I am running this in Visual Studio and it does initially run, but I realized it does not compile with GCC. Feel free to leave some code suggestions, but my main goal is to figure out the program-breaking issue.

            Grenade spawns in the wrong location
            Asked 2021-Jun-11 at 21:37

            In my game I want to have a floating monster that's attack throws a grenade at the player. My problem is that the grenade only spawns in 0, 0, 0. In my script I make it so that the zombies spawns in on its own location but for some reason that doesn't work. I tried making it spawn by having the spawn location equal new Vector3(100, 100, 100) but it still spawned at 0, 0, 0. I know that the co-routine runs because I put a Debug.Log. Thanks for the help!

            Edit #2: I can't have a rigidbody on the script. I have edited the movement script and I have found that no mater what if a rigidbody is added then it will go to 0, 0, 0.

            When you place your Header component in the return or render of a parent component make sure you use

            and not {Header}

            additionally if that's not the problem you can check this link which is the official react thread on that error.

            Also posting how you render the component that is throwing the error would be very helpful.

            I think it's a good idea to make one more layer between ObjectPool and Monster classes that will manage what you want. It will complete Single responsibility principle of SOLID.

            So both classes ObjectPool and Monster will not depend on each other and every class will be making their jobs.

            Because all of your returns are in the while loop. From msdn: msdn

            • The while statement: conditionally executes its body zero or more times.

            Meaning that is not guaranteed that the code inside the while loop will be executed at all. It might just skip the whole, but no returns after it, that's why you are getting an error: "Not all code paths return a value", although multiple paths returns a value, NOT all path.

            You specified that the mattaVag variable is true at the beginning but the compiler doesn't know it. If this loop will be executed at least one time anyway, change it to do...while. Or place the return b; outside your loop

            Dynamically create, animate and then remove multiple HTML elements in a Vue2 project
            Asked 2021-May-31 at 18:16

            With Vue 2 (and Nuxt), on click of a button I want to show a little animation of a "-1" moving up a few pixels from the button and disappearing after a second. Each time a button is clicked a new -1 should appear while the old ones are still in motion. That's where my problem is, I can create an animation of just one -1, but I fail to make multiple at the same time.

            You're not far from the right structure. The first issue to fix is that your keys cannot be array indexes here. When you remove an item from the array, the won't be able to distinguish old item 0 from new item 0 and apply the correct effect. I've expanded each wound into an object with a (notional) unique ID like so, but of course you could take various approaches:

            In Result object with ID 385687 you have a property backdrop_path being null. Adjust your Result object and make the property nullable:

            String? backdropPath;
