QUESTION
I'm trying change version for spring-cloud-function-adapter-aws from 3.0.7.RELEASE to either 3.1.7 or 3.2.3 (as Spring Cloud Function Vulnerability CVE-2022-22963) but getting error as it is not able to find the class
java.lang.NoClassDefFoundError: org/spring framework/boot/ApplicationContextFactory at org.springframework.cloud.function.context.FunctionalSpringApplication.(FunctionalSpringApplication.java:67) at org.springframework.cloud.function.context.AbstractSpringFunctionAdapterInitializer.springApplication(AbstractSpringFunctionAdapterInitializer.java:378) at org.springframework.cloud.function.context.AbstractSpringFunctionAdapterInitializer.initialize(AbstractSpringFunctionAdapterInitializer.java:121) at org.springframework.cloud.function.adapter.aws.SpringBootStreamHandler.initialize(SpringBootStreamHandler.java:61) at org.springframework.cloud.function.adapter.aws.SpringBootStreamHandler.handleRequest(SpringBootStreamHandler.java:53) Caused by: java.lang.ClassNotFoundException:

...ANSWER
Answered 2022-Apr-15 at 17:28You need to upgrade Spring Boot as well. You are using 2.3.0 and ApplicationContextFactory was added in 2.4, but 2.4.x is no longer supported.
You should upgrade to Spring Boot 2.5.12 or 2.6.6.

QUESTION
I am trying to create a Spring Cloud Function application which will have multiple functions defined in it. I need to use the Functional Bean definition approach for reduced cold start time. The jar will be deployed in AWS Lambda.
The code works in local environment and I am able to curl for all the functions defined. However when deployed in Lambda , the function is not getting located by AWS.
The code runs and is working as expected on Lambda ,if there is only 1 function defined.
I will mention below the things that I have tried.
- Followed the Spring Doc to create the project
- This works fine in local and also runs in Lambda with Handler
org.springframework.cloud.function.adapter.aws.SpringBootStreamHandler::handleRequest
as per the comment by Thannasi on mydeveloperplanet blog post - Next I added few more functions and registered them with the Generic ApplicationContext

QUESTION
I am trying to automate a function call, so that I can produce one data frame by rotating in dependent variables such as x, y, and z and using various combinations of grouping variables such as year and race or separately, year, race, and city.
In more detail.
In my minimal example, I have three dependent variables, x,y,z. I also have several grouping variables. For each call, I need to count the number of 1’s. I also need to add a new column which contains string values which reflect the dependent variable that was used.
I was able to write a function that produces the counts when I specify the two grouping variables and the dependent variable. In the real problem, for each of about a dozen dependent variables, I will have to group in a number of different ways. I may have one, two, or three grouping variables. Outside of the function, I added the character column that gives information on what the variables were. I think that inside the function I should have a case_when()statement that says something like:

Answered 2021-Apr-06 at 22:00If we want to pass as quoted or unquoted, we could convert to symbol with ensym
and evaluate (!!
) . Here, we are changing only the 'var1' part, the grouping columns can also be changed (if we want to do loop more than 1 inputs, use map2
(for 2 variable inputs) or pmap
(for >= 2))
QUESTION
The author of Advanced R certainly knows R better than I do. However, Section 9.4.5 contains the following claim:
Map()
vectorises over all arguments so you cannot supply arguments that do not vary.
But this seems obviously false. For example, I can easily write the following:

QUESTION
I am coming from the Embedded Systems domain with more than 3 years experience. In my current project, at the beginning, I was only responsible for only software development and the Team consisted of 3 people. But, as time passes, hardware eng. and project lead eng. left the job respectively. So far, the project moved with a zero- architecture documentation to give an output as fast as possible. Later, new project lead took over the project and started from the begining with applying V-model. We started to create product specs->HLR->DLR on EXCEL. But now, He left the job too :). Now, I am alone on my way with nearly 700 pieces of well written product requirements. Anyway, I started to gathering and classfying requirements as non-functional, functional, business, stakeholder etc. As gathering non-functionals, I also classified them scalability, performance, regulatory, design contrains etc. So far, I did not draw any use-case. Please verify me here, what I know is that input of use-case are functional requirements. So, I created a use-case cards and now I am planning to write use-case cards for each functional requirements then also write a sequence diagram for each use-case card. Now till here, am I going right ? Does notations used in use-case such as include, extend etc. help me to create class diagram ? Is this also right way ?
...ANSWER
Answered 2021-Mar-14 at 12:33When Ivar Jacobson invented use-cases he aimed at a development method that would be driven by the use-cases and allow to methodically derive the implementation from the use cases. That was his vision end of the 80s. His first attempt was called Objectory, which was bought by a larger company and lead to Rational Unified Process, which was generalized to be less proprietary into the Unified Software Development Process (Unified Process, or UP in short).
There is in particular one practice that allows to translate a use-case into classes: the Entity Control Boundary approach: use-cases become «control»
classes, links between use-cases and actors become «boundary»
classes, and «entity»
classes are created for the business objects identified in (or derived from) the use-case narratives.
Once these first candidate classes are modelled, further work is undertaken during the design and classes may get reorganized to best fit into the solution (e.g. several boundary classes are regrouped for designing the GUI, and may thereafter be decomposed into UI elements, etc...).
But is this the best approach in your case?UP is iterative and incremental, and fits well into modern version of the V-model, since the early iterations of the elaboration phase aim to stabilize the architecture and teh components (or sub-systems).
However, this may be a very time-consuming approach, especially considering the huge number of use-cases that you have. If you look at all the questions that modelling a use-case usually raises, especially if you add «include»
and «extend»
, you risk to spend a lot of time (more than 300 days?) to draw robust use-case diagrams. And then, using ECB, your requirements might be outdated before you finish the design!
On the other side, some non-academic authors claim that every system has 3 to 5 really main use-cases: as a user I don't have 700 goals for using a system. So you'd better identify these and see how they relate. It's probable that many of the other requirements are far too detailed and could easily be assigned as additional information for the main use-cases.
In a similar thought, Ivar Jacobson has adapted his method to the current software engineering reality, with the use-case 2.0 approach. Don't misunderstand me, the UML would still be the same, but ECB no longer appears (modern frameworks influence much more the design of the boundaries than the use-case model, and entities are modelled using more focused approaches, such as DDD).
The idea behind use-case 2.0 is to slice the main use-cases into several smaller parts and start to develop something that makes sense for the user and can then be further refined.

To improve my R programming and simplify my code, I'm trying to replace a 'for' loop with 'lapply', 'map', or a similar variant. I want to perform a function using 2 minute time intervals from my time series data. When I try to pass just a subset of the data using one of the functionals, 'map' or 'lapply', I get a 'subscript out of bounds error'. Any ideas?
