kandi X-RAY | closest Summary
closest is a polyfill for #Element.closest. The #Element.closest method returns the closest element that matches a selector. It returns the element itself, one of its ancestor, or null if there isn't any match. This is especially useful for delegating events. The script is approximately 428 bytes, or 257 bytes when gzipped.

QUESTION
I want to do a simple calculation for each row by group, but I need to refer to a previous row that meets certain conditions. I want to create a new variable, results. For each row in each group, I want to find the closest row above where tag == "Y" and code is not NA. Then, I want to use the value from that row, and multiply by the value in the current row.
Minimal Example

QUESTION
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?
ReferencesThis 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.
...ANSWER
Answered 2022-Jan-01 at 18:43The JNDI feature was added into Log4j 2.0-beta9.
Log4j 1.x thus does not have the vulnerable code.

I want to create a polynomial ring which has float Coefficients like this. I can create with integers but, Floats does not work.
...ANSWER
Answered 2022-Jan-18 at 23:30While I do not have previous experience with this particular (from appearances, rather sophisticated) package Oscar.jl, parsing this error message tells me that the function you are trying to call is being given a BigFloat as input, but simply does not have a method for that type.
At first this was a bit surprising given that there are no BigFloats in your input, but after a bit of investigation, it appears that the culprit is the following
QUESTION
I'm converting an object based on reflection like this.
...ANSWER
Answered 2022-Jan-01 at 18:01I can't think of a solution that's significantly different to yours, fundamentally it feels like it's a custom logic to determine whether a property value is "empty" or not.
Perhaps a pattern matched switch expression might make the code a little cleaner, however, for example:

I'm trying to setup an Airflow DAG that provides default values available from dag_run.conf. This works great when running the DAG from the webUI, using the "Run w/ Config" option. However when running on the schedule, the dag_run.conf dict is not present, and the task will fail, e.g.
ANSWER
Answered 2021-Oct-02 at 23:53You could use DAG params to achieve what you are looking for:
params (dict) – a dictionary of DAG level parameters that are made accessible in templates, namespaced under params. These params can be overridden at the task level.
You can define params at DAG or Task levels and also add or modify them from the UI in the Trigger DAG w/ config section.
