Story: in my java code i have a few ScheduledFuture's that i need to run everyday on specific time (15:00 for example), the only available thing that i have is database, my current application and openshift with multiple pods. I can't move this code out of my application and must run it from there.

Problem: ScheduledFuture works on every pod, but i need to run it only once a day. I have a few ideas, but i don't know how to implement them.

Idea #1: Set environment variable to specific pod, then i will be able to check if this variable exists (and its value), read it and run schedule task if required. I know that i have a risk of hovered pods, but that's better not to run scheduled task at all than to run it multiple times.

Idea #2: Determine a leader pod somehow, this seems to be a bad idea in my case since it always have "split-brain" problem.

Idea #3 (a bit offtopic): Create my own synchronization algorithm thru database. To be fair, it's the simplest way to me since i'm a programmer and not SRE. I understand that this is not the best one tho.

Idea #4 (a bit offtopic): Just use quartz schedule library. I personally don't really like that and would prefer one of the first two ideas (if i will able to implement them), but at the moment it seems like my only valid choice.

UPD. May be you have some other suggestions or a warning that i shouldn't ever do that?

My brain froze with this advanced filtering. This task has exceeded my basic knowledge of filter, map etc.

Here I have an array with nested objects with array:

I've seen a lot of questions about JSON and PowerShell these past hours and none helped me find a solution to this particular problem. And I'm sure it's something easy.

I want to extract all the url fields of the plugins objects in this JSON object (original URL is this: https://updates.jenkins.io/update-center.json):

I do have a data frame where I need to edit the Diseases names. Each Disease has several rows related to it. For some reason, when I use str_replace_all, the replacement does not happen for two conditions ("Peripheral neuropathies (excluding cranial nerve and carpal tunnel syndromes)", "Venous thromboembolic disease (Excl PE)"). There is no warning or error message in the output, so I can't figure out what is the issue. Does anyone have any ideas?

Solved

I am trying to figure out why my solution is wrong. Made both, second is correct. I like the first better, because the intervals are more manageable and pleasing for my bad programming brain. And quite frankly, I am kind of lost as to what happens from pH 8 (Neutral) and up (solution 2). Therefore I would like to continue to work in this style for future assignment, rather than solution 2 (correct). However, solution 1 that I prefer is wrong and returns weakly though it should be strongly acidic Why is that and how can this be fixed?

Def: assigning category based on pH (2.3)

pH & category
0–2 Strongly acidic
3–5 Weakly acidic
6–8 Neutral
9–11 Weakly basic
12–14 Strongly basic
Anything else falls in pH out of range

I have a database that allows for more than one ethnicity per person. Unfortunately, our answers are essentially Yes Hispanic, Not Hispanic, and Unknown, and there are some who do indeed have multiple selections. I need to run a large query that pulls lots of info, one of which is ethnicity, and I want to "convert" those that have multiple selections as Unknown.

person_ethnicity_xref table:

mstr_lists table:

I've been struggling with this as I can't use a For XML Path with two tables, so I'm now trying to use the logic of Case When count(ethnicity_ID)>1 then 'Unknown' Else Ethnicity End

Here's what I have

I can actually run the bot, it will let mi interact with the other 3 commands, but when trying to do the "kickembed" it will fail and give me the error "client.commands.get('kickembed').execute(message,args,Discord)" ^ Cannot read property of 'execute' of undefined

tbh, i tried everithing, my little brain cant work this out, tysm for your time!

So I have this code:

I was trying to change my coc.nvim autocomplete key, and found this question in Stack Overflow, but the guy who answer this question doesn't explain really good how to customize it as you want, so I will explain it to help the NeoVim users that are racking the brain for this as I was.
