            Multiple DAGs run on Airflow 2.0 unintentionally at a time
            Asked 2021-May-06 at 09:25

            I installed Airflow with postgreSQL for the first time. However, after activating DAG on the web, about 16 DAGs are created at the same time as shown in the picture below. enter image description here

            As a test, I made a dag that enters the current date into the db for 10 seconds once a second. If intended, it should be generated one row per second, but the problem above creates multiple rows per second. enter image description here

            Below is the DAG code.



            Answered 2021-May-06 at 09:25

            Airflow has a default True value for catchup_by_default setting so if you didn't change the defaults you must specify catchup=False in your DAGs if you don't want them to backfill runs from the given start_date.

            The problem may be caused by using gradle in the wrong path. You need to run gradle in the same directory as the Build.gradle file.

            If you are using Azure DevOps build pipeline, the root directory path of the repository is $(system.defaultworkingdirectory).

            Other than that, you can try gradle clean build instead of gradle build.



            runing an Azure DevOps pipeline for a Talend ESB project maven error

            According to the error message log, this error generally occurs when Maven could not download dependencies. Possible causes for this error are:

            1. The POM misses the declaration of the which hosts the artifact.
            2. The repository you have configured requires authentication and Maven failed to provide the correct credentials to the server. In this case, make sure your ${user.home}/.m2/settings.xml contains a declaration whose matches the of the remote repository to use. See the Maven Settings Reference for more details.
            3. The remote repository in question uses SSL and the JVM running Maven does not trust the certificate of the server.
            4. There is a general network problem that prevents Maven from accessing any remote repository, e.g. a missing proxy configuration.
            5. You have configured Maven to perform strict checksum validation and the files to download got corrupted.
            6. Maven failed to save the files to your local repository, see LocalRepositoryNotAccessibleException for more details.

            Javascript library for random prime number generation
            Asked 2020-Apr-08 at 13:29

            I am currently working on a Javascript team project which involves cryptography, a field I do not master, unfortunately.

            I want my program to be as safe as possible, if possible industry-level safe, and as such I have been searching for community-approved implementations of random big prime number generation algorithms. I explored several libraries such as Node.js Crypto and Web Cryptography API, but I did not find there a straightforward function that returns a random big probable prime number.

            I found a library that contains what I want (in the link below), but its creators say that I should prefer the libraries I cited above for cryptographic purposes.


            Is there a preferred way among the community to generate such prime numbers in Javascript ? If so, which libraries does it use ?

            Thank you in advance for your help.

            Publishing a .NET Core / Angular 4 Project to Netlify
            Asked 2020-Feb-26 at 00:06

            Does anyone have experience publishing a .NET/Angular project to Netlify? I'm using the Angular Microsoft.AspNetCore.SpaTemplates template. On Netlify, I'm getting a non-zero exit code that's preventing me from publishing. Here is my output:

            As we mentioned to you in your helpdesk ticket on this same topic, our deploy environment is very naked - you have to:

            1. specify dependencies that we can automatically install - npm/yarn deps, bower deps, gems and python packages.
            2. install other dependencies yourself. the 'dotnet' program will be one of this type. We don't have it in our install environment, so you need to somehow import a copy of it into the environment. Seems like you can download the entire SDK here: and then you need to import ONLY what is necessary for your build - it will take a very long time to build your site if we have to download the entire SDK, so see what you can trim down to get 'dotnet' to run.

            For the purposes of #2, you'll probably need to test things in our build environment. How to do that, and details you'll need about the build environment such as OS type so you can download the right version of the SDK are described in this article:


            This will take some work on your part. It will not be trivial. It is not something we can help with in more detail than that for free customers unless you come with specific questions and examples.

            To address some thoughts in the comments:

            • is indeed our build script
            • 9:46:52 AM: /opt/build/ line 427: dotnet: command not found means that literally there is no dotnet command available to run - not that some config file is missing.
            • we only try to run it once since you have set your command to use && to chain several commands - one fails, the whole chain fails, and we don't need to run it two more times once the first failure occurs :)



            Java. LoraWan package decription. AES-128
            Asked 2019-Dec-28 at 13:53

            At first glance, I have the same problem as many. But my case a bit more complex.

            Project language: Java 11
            Network Server: Orbiwise NS (
            Device: (STM32 + Wifi module) connection via Lorawan gateway to Orbiwise and using TCP socket via wifi.

            Answered 2019-Dec-28 at 13:48

            Your ciphertext offset is off by 2 (as there are 3 option bytes instead of 1, no doubt). Printing out intermediate results or performing full parsing of the header bytes should show you that, which is why I mentioned it in the comments. Note that increasing the offset of 9 by 2 may also affect the ciphertext size, as the end of the ciphertext is fixed.

            Furthermore, you are using Cipher.DECRYPT_MODE while the protocol only uses the cipher in forward mode. Counter mode (used by CCM and CCM* ciphers) only uses the cipher in the forward mode as they generate a key stream that is then XOR-ed with the plaintext stream or ciphertext stream to encrypt / decrypt respectively. The "decryption" part in the protocol only is about performing the final XOR of the generated key stream to the ciphertext rather than the plaintext.

            Of course, ECB mode - used to simply implement a single block encrypt in this case - doesn't require an IV, so that part of the code is spurious.
