kandi X-RAY | swan Summary

swan is a Scala library typically used in Code Quality, Code Analyzer applications. swan has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

SWAN is a static program analysis framework that enables deep dataflow analysis for Swift applications (incl. iOS/macOS). Its applications include finding API misuses using typestate analysis and detecting security vulnerabilities using taint analysis. SWAN parses plain-text Swift Intermediate Language (SIL). We have developed an intermediate representation (IR), called SWIRL. It is simple, well documented, and easy to understand. Any analysis engine should be able to analyze SWIRL without having to handle complex semantics. We aim to provide developers and researchers with an easy-to-use and well-documented platform for analyzing Swift applications. :construction: SWAN is WIP. However, we are working on a pre-release to get the community involved. We will release an extensive video playlist explaining how SWAN works, which should enable you to experiment with SWAN.

            What you are trying to achieve is called 'Reflection'. Unfortunately, the VBA language does not have reflection so you cannot directly achieve what you want.

            You could emulate what you want using a 'wrapper' class to allow a name to be associated with a specific dictionary.

            The example below implements a simple wrapper class which allows the name to be set, but not changed, and exposes the scripting.dictionary via the Host property.

            VPN to access multiple VPC
            Asked 2022-Jan-21 at 15:25

            I have VPC A and VPC B in my cloud provider, I have a VPC peering between them, so hosts in one can access the other.

            I have created a VPN in VPC A which gives me access to it, but I would like to be able to access VPC B as well, without having to setup another VPN, is there a way for me to do that?

            I have started with OpenVPN Access Server but I think I'm moving to Swan or OpenConnect due to initial costs that I don't want to have now.

            I'm not very experienced with networking, so suggestions are very welcome.

            You can do that and we have this explained in the following page: How can I access resources in a peered VPC over Client VPN?

            To provide access to resources in a peered VPC over a client VPN we need to do:

            1. Create a VPC peering connection between the VPCs.
            2. Test the VPC peering connection. Confirm that instances in both VPCs can communicate as if they're in the same network.
            3. Create a Client VPN endpoint in the same Region as the target VPC.
            4. Associate the subnet that you previously identified with the Client VPN endpoint that you created in step 3.
            5. Add an authorization rule to give clients access to the target VPC. For Destination network to enable, enter the IPv4 CIDR range of the VPC.
            6. Add an endpoint route to direct traffic to the peered VPC. For Route destination, enter the IPv4 CIDR range of the peered VPC. For Target VPC Subnet ID, select the subnet that you associated with the Client VPN endpoint.
            7. Add an authorization rule to give clients access to the peered VPC. For Destination network, enter the IPv4 CIDR range of the peered VPC.
            8. Add a rule to the security groups for your resources in both VPCs. Use this rule to allow traffic from the security group that was applied to the subnet association in step 4. Then, confirm that the network access control lists (ACLs) in both VPCs allow traffic between the target VPC and the peered VPC.

            A couple of points worth mentioning..

            1. Your example code in file "courses.py" is inserting grades as a string that represents an array, not an actual array. This was pointed out by Matt in the comments, and you requested an explanation. Here is my attempt to explain - if you insert a string that looks like an array you cannot perform $unwind, or $lookup on sub-elements because they aren't sub-elements, they are part of a string.
            2. You have array data in courses that hold students grades, which are the datapoints that are desired, but you start the aggregation on the student collection. Instead, perhaps change your perspective a bit and come at it from the courses collections instead of the student perspective. If you do, you will may re-qualify the requirement as - "show me all courses and student grades where student id is 0".
            3. Your array data seems to have a datatype mismatch. The student id is an integer in your string variable "array", but the student collection has the student id as a string. Need to be consistent for the $lookup to work properly (if not wanting to perform a bunch of casting).

            But, nonetheless, here is a possible solution to your problem. I have revised the python code, including a redefinition of the aggregation...

            The name of my test database is pythontest as seen in this code example. This database must exist prior to running the code else an error.

            Given source and target dataframes in Pandas, I need to update a column in the target dataframe by an amount specified in a column of the source dataframe, for every match on a key column.

            In the example below, the source and target dataframes are RecetteDF and InventaireDF, respectively. The key column common to both is Codes interne. Quantite Reserver in the target has to be incremented with values from Quantite requise from the source on matching key.

            You can use pandas.merge to pull Quantite requise in from RecetteDF whenever you have a match. The merge should be done using left, so that we preserve rows of InventaireDF even when there is no match. Here is some code that should work:

            Install swan

            For now, you will need to build the framework to use SWAN, but soon we will make a release available. We have tested SWAN on macOS Big Sur Xcode 12 and Ubuntu 20.04. You need Xcode Command Line Tools installed for macOS, or the latest Swift release for Linux (see this). Anything involving "Xcode" will not work on Linux, but you should be able to build Swift Package Manager projects. Add your GitHub username and personal access token (with read:packages) to jvm/gradle.properties. The SPDS dependency requires this. Do not push these credentials. Copy swift-demangle to /usr/local/bin/ or add it to $PATH. On Linux, swift-demangle is distributed alongside swiftc, so you do not need to do this step. You also need swiftc and xcodebuild to be on $PATH. Run build.sh in the repo root. You can also run the nested build.sh scripts from root to build separate toolchain components. All toolchain components should now be available in lib/. If you want to make sure everything works, you can run run ./gradlew build in jvm/ and ./test.bash in tests/.
