            e: this has been fixed through Spring Boot 2.6.5 (see https://github.com/spring-projects/spring-boot/issues/30243)

            Since upgrading to Spring Boot 2.6.X (in my case: 2.6.1), I have multiple projects that now have failing unit-tests on Windows that cannot start EmbeddedKafka, that do run with Linux

            There is multiple errors, but this is the first one thrown

            Known bug on the Apache Kafka side. Nothing to do from Spring perspective. See more info here: https://github.com/spring-projects/spring-kafka/discussions/2027. And here: https://issues.apache.org/jira/browse/KAFKA-13391

            You need to wait until Apache Kafka 3.0.1 or don't use embedded Kafka and just rely on the Testcontainers, for example, or fully external Apache Kafka broker.

            I have added android:exported="true" to my only activity in manifest but still getting below error after updating compile sdk and target sdk version to 31.I also tried rebuilding the project , invalidating cache and restart but that didn't helped

            Error- Apps targeting Android 12 and higher are required to specify an explicit value for android:exported when the corresponding component has an intent filter defined. See https://developer.android.com/guide/topics/manifest/activity-element#exported for details.

            Answered 2021-Oct-05 at 10:38

            After the build has failed go to AndroidManifest.xml and in the bottom click merged manifest see which activities which have intent-filter but don't have exported=true attribute. Or you can just get the activities which are giving error.

            Add these activities to your App manifest with android:exported="true" and app tools:node="merge" this will add exported attribute to the activities giving error.

            Configuring compilers on Mac M1 (Big Sur, Monterey) for Rcpp and other tools
            Asked 2022-Feb-10 at 21:07

            I'm trying to use packages that require Rcpp in R on my M1 Mac, which I was never able to get up and running after purchasing this computer. I updated it to Monterey in the hope that this would fix some installation issues but it hasn't. I tried running the Rcpp check from this page but I get the following error:

            Currently (2022-02-05), CRAN builds R binaries for Apple silicon using Apple clang (from Command Line Tools for Xcode 12.4) and an experimental build of gfortran.

            If you obtain R from CRAN (i.e., here), then you need to replicate CRAN's compiler setup on your system before building R packages that contain C/C++/Fortran code from their sources (and before using Rcpp, etc.). This requirement ensures that your package builds are compatible with R itself.

            A further complication is the fact that Apple clang doesn't support OpenMP, so you need to do even more work to compile programs that make use of multithreading. You could circumvent the issue by building R itself and all R packages from sources with LLVM clang, which does support OpenMP, but this approach is onerous and "for experts only". There is another approach that has been tested by a few people, including Simon Urbanek, the maintainer of R for macOS. It is experimental and also "for experts only", but seems to work on my machine and is simpler than trying to build R yourself.

            Instructions for obtaining a working toolchain

            Warning: These instructions come with no warranty and could break at any time. They assume some level of familiarity with C/C++/Fortran program compilation, Makefile syntax, and Unix shells. As usual, sudo at your own risk.

            I will try to address compilers and OpenMP support at the same time. I am going to assume that you are starting from nothing. Feel free to skip steps you've already taken, though you might find a fresh start helpful.

            I've tested these instructions on a machine running Big Sur, and at least one person has tested them on a machine running Monterey. I would be glad to hear from others.

            1. Download an R binary from CRAN here and install. Be sure to select the binary built for Apple silicon.

            2. Run

            This seems to be a bug in Tensorflow 2.7 when using model.save combined with the parameter save_format="tf", which is set by default. The layers RandomFlip, RandomRotation, RandomZoom, and RandomContrast are causing the problems, since they are not serializable. Interestingly, the Rescaling layer can be saved without any problems. A workaround would be to simply save your model with the older Keras H5 format model.save("test", save_format='h5'):

            pymongo [SSL: CERTIFICATE_VERIFY_FAILED]: certificate has expired on Mongo Atlas

            I am using MongoDB(Mongo Atlas) in my Django app. All was working fine till yesterday. But today, when I ran the server, it is showing me the following error on console



            Answered 2021-Oct-03 at 05:57

            This is because of a root CA Let’s Encrypt uses (and Mongo Atals uses Let's Encrypt) has expired on 2020-09-30 - namely the "IdentTrust DST Root CA X3" one.

            The fix is to manually install in the Windows certificate store the "ISRG Root X1" and "ISRG Root X2" root certificates, and the "Let’s Encrypt R3" intermediate one - link to their official site - https://letsencrypt.org/certificates/

            Vue 3: Module '"../../node_modules/vue/dist/vue"' has no exported member
            Asked 2022-Jan-24 at 08:38

            After updating my npm packages, some of the imports from the 'vue' module started showing errors:

            TS2305: Module '"../../node_modules/vue/dist/vue"' has no exported member 'X'

            where X is nextTick, onMounted, ref, watch etc. When serving the project, Vue says it's "failed to compile". WebStorm actually recognizes the exports, suggests them and shows types, but the error is shown regardless. Some exports like computed and defineComponent work just fine.

            What I've tried:

            • Rollback to the previously used Vue version "3.2.2" > "3.0.11". It makes the abovementioned type errors disappear, but the app stops working entirely, showing lots of TypeError: Object(...) is not a function errors in console and not rendering the app at all. In the terminal, some new warnings are introduced: "export 'X' (imported as '_X') was not found in 'vue' where X is createElementBlock, createElementVNode, normalizeClass and normalizeStyle.
            • Rollback other dependencies. None of the ones that I tried helped fix the problem, unfortunately.
            • Manually declare the entirety of 'vue' module. We can declare the 'vue' module exports in shims-vue.d.ts, and it actually makes the errors disappear, however, this seems like a terrible, time-consuming workaround, so I would opt out for a better solution if possible.

            My full list of dependencies:



            Answered 2021-Aug-15 at 13:53

            That named exports from composition API are unavailable means that vue is Vue 2 at some place which has only default export. Since Vue 3 is in dependencies and both lock file and node_modules were refreshed, this means that Vue 2 is nested dependency of some direct dependency.

            The problem needs to be investigated in lock file. It shows that @vue/cli-plugin-unit-jest@4.5.13 depends on vue-jest@3 which depends on vue@2.

            A possible solution is to upgrade @vue/cli-plugin-unit-jest to the latest version, next. The same likely applies to other @vue/cli-* packages because they have matching versions.
