            How do purely functional languages handle index-based algorithms?
            Asked 2022-Apr-05 at 12:51

            I have been trying to learn about functional programming, but I still struggle with thinking like a functional programmer. One such hangup is how one would implement index-heavy operations which rely strongly on loops/order-of-execution.

            For example, consider the following Java code:

            This is not an index-heavy operation, in fact you can do this with a one-liner with scanl1 :: (a -> a -> a) -> [a] -> [a]:

            You are running the project via Java 1.8 and add the --add-opens option to the runner. However Java 1.8 does not support it.

            So, the first option is to use Java 11 to run the project, as Java 11 can recognize this VM option.

            Another solution is to find a place where --add-opens is added and remove it. Check Run configuration in IntelliJ IDEA (VM options field) and Maven/Gradle configuration files for argLine (Maven) and jvmArgs (Gradle)

            Springboot 2.6.0 / Spring fox 3 - Failed to start bean 'documentationPluginsBootstrapper'
            Asked 2022-Mar-25 at 06:14

            I'm trying to initiate a Springboot project using Open Jdk 15, Springboot 2.6.0, Springfox 3. We are working on a project that replaced Netty as the webserver and used Jetty instead because we do not need a non-blocking environment.

            In the code we depend primarily on Reactor API (Flux, Mono), so we can not remove org.springframework.boot:spring-boot-starter-webflux dependencies.

            I replicated the problem that we have in a new project.: https://github.com/jvacaq/spring-fox.

            I figured out that these lines in our build.gradle file are the origin of the problem.

            This problem's caused by a bug in Springfox. It's making an assumption about how Spring MVC is set up that doesn't always hold true. Specifically, it's assuming that MVC's path matching will use the Ant-based path matcher and not the PathPattern-based matcher. PathPattern-based matching has been an option for some time now and is the default as of Spring Boot 2.6.

            As described in Spring Boot 2.6's release notes, you can restore the configuration that Springfox assumes will be used by setting spring.mvc.pathmatch.matching-strategy to ant-path-matcher in your application.properties file. Note that this will only work if you are not using Spring Boot's Actuator. The Actuator always uses PathPattern-based parsing, irrespective of the configured matching-strategy. A change to Springfox will be required if you want to use it with the Actuator in Spring Boot 2.6 and later.

            I'm facing a weird issue. Before I updated my Android Studio, everything went fine in flutter doctor. Once I've updated Android Studio, when I run the doctor, it's showing "Unable to find bundled Java version". I've already downloaded Java installer and installed it on my M1 Mac, but after I restarted, running flutter doctor still shows the same error. The weird thing is, when I uninstall the Arctic Fox version and re-install the older Android Studio version, everything goes fine again when running the doctor. How can I resolve this?

            Upgrade google analytics to firebase analaytics. Hope it'll solve your problems.Also upgrade all the library what're you using.

            For me below solutions solve the problem.

            Add PendingIntent.FLAG_IMMUTABLE to your pending intents.

            Here is an example -

            PendingIntent pendingIntent = PendingIntent.getActivity(this, alarmID, notificationIntent, PendingIntent.FLAG_IMMUTABLE);

            Log4j vulnerability - Is Log4j 1.2.17 vulnerable (was unable to find any JNDI code in source)?
            Asked 2022-Feb-01 at 15:47

            With regard to the Log4j JNDI remote code execution vulnerability that has been identified CVE-2021-44228 - (also see references) - I wondered if Log4j-v1.2 is also impacted, but the closest I got from source code review is the JMS-Appender.

            The question is, while the posts on the Internet indicate that Log4j 1.2 is also vulnerable, I am not able to find the relevant source code for it.

            Am I missing something that others have identified?

            Log4j 1.2 appears to have a vulnerability in the socket-server class, but my understanding is that it needs to be enabled in the first place for it to be applicable and hence is not a passive threat unlike the JNDI-lookup vulnerability which the one identified appears to be.

            Is my understanding - that Log4j v1.2 - is not vulnerable to the jndi-remote-code execution bug correct?

            References

            This blog post from Cloudflare also indicates the same point as from AKX....that it was introduced from Log4j 2!

            Update #1 - A fork of the (now-retired) apache-log4j-1.2.x with patch fixes for few vulnerabilities identified in the older library is now available (from the original log4j author). The site is https://reload4j.qos.ch/. As of 21-Jan-2022 version 1.2.18.2 has been released. Vulnerabilities addressed to date include those pertaining to JMSAppender, SocketServer and Chainsaw vulnerabilities. Note that I am simply relaying this information. Have not verified the fixes from my end. Please refer the link for additional details.
