chronos | Fault tolerant job scheduler for Mesos | Cron Utils library

I am using Mesos 1.3.1 and Chronos in my local. I currently have 100 jobs scheduled every 30 minutes for testing.

Sometimes the tasks get stuck in RUNNING status forever until I restart the Mesos agent that the task is stuck. No agent restarted during this time.

I have tried to KILL the task but its status never gets updated to KILLED while the logs in Chronos say that successfully received the request. I have checked in Chronos that it did update the task as successful and end time is also correct but duration is ongoing and the task is still in RUNNING state.

Also the executor container is running forever for the task that are stuck. I have the executor container that will sleep for 20 seconds and set the offer_timeout to 30 seconds and executor_registration_timeout to 2 minutes.

I have also included Mesos reconciliation every 10 minutes but it updates the task as RUNNING every time.

I have also tried to force the task status to update again as FINISHED before the reconciliation but still not getting updated as FINISHED. It seems like the Mesos leader is not picking up the correct status for the stuck task.

I have tried to run with different task resource allocations (cpu: 0.5,0.75,1...) but does not solve the issue. I changed the number of jobs to 70 for every 30 minute but still happening. This issue is seen once per day which is very random and can happen to any job.

How can I remove this stuck task from the active tasks without restarting the Mesos agent? Is there a way to prevent this issue from happening?

How to find the local timezone offset in Rust? is there an easy way to find it without using a crate like Chronos?

Recently I installed Neverware's version of Chromium OS, called Cloudready, on VirtualBox 6.1, to develop Python apps for Chromebooks. This version of Chromium OS is 48.0.2564.116 developer build (newer versions won't install due to graphics incompatibilities). As I do not have a Google Account, I login into Chromium OS as Guest user (somehow I have administrative powers as Guest, which is good for my developmental purposes).

I found that Python 2.7.3 was preinstalled. I tried to install Python 3.6, and to do so, I tried to find the preinstalled package manager, which I eventually found. The package manager that is preinstalled (portage), doesn't install anything, because it gives errors similar to this one:

In Typescript, I have a controller class that has a method that I want to run daily at 5am.

My first thought was to schedule something using node-cron or node-scheduler, but these seem to be strictly for node projects, not typescript.

What I need to happen is a) transpile my entire typescript project into node and then b) Run the method as scheduled.

There doesn't seem to be any explanation on how to do this though. The explanations I do see are all about running a node.js function on some schedule, such as this one: I need a Nodejs scheduler that allows for tasks at different intervals

The below code illustrates my best approximation at what I'm trying to do.

I'm looking for solution that allow me to set lifecycle policy for object in minio storage.

What do I want?
I want to delete objects from minIO storage after 30 min.

Possible, but not suitable solution

1. Chronos + mc rm -f --older-than 30m.
2. AWS S3 Lifecycle rule (it doesn't allow to set lifecycle using minutes).

I'm learning F# and struggling trying to use discriminated unions. I have a simple case where I'm trying to use Map.map on a simple discriminated union of the type Map but its saying there is a type mismatch. I'm basically just trying to use the type Prices as a Map

Here is a simplified example:

I am running into composer/installation errrors on wamp64 setup on Windows 10... had this working previously on older app but now starting new app on 4.0.3 and running into dependency issues

Below is output - Any thoughts on why it's not finding any matching packages? the "myapp" folder is created and cakephp source is copied but then a number of dependencies show "no matching package found"

Can these packages be ignored? some, such as migrations fall under "require" in the composer.json I have tried both the below command and composer create-project --prefer-dist "cakephp/app:^4.0" myapp

I'm trying to build a JavaFX project with NetBeans but when i run it i have a this :

I changed the language of my datepicker but the message that appears is still in English. I know it is inside ngx-bootstrap / chronos / locale / locale.defaults.ts where it brings the following information
