It's that time of the week again. So wonderful devs, what did you learn this week? It could be programming tips, career advice etc.

Feel free to comment with what you learnt and/or reference your TIL post to give it some more exposure.

Summarize a concept that is new to you.

And remember, if something you learnt was a big win for you, then you know where to drop it as well.👇👇🏻👇🏼👇🏽👇🏾👇🏿

I learned about anacron, cron's companion. Just like cron you can use it to schedule some task but the difference is it doesn't assume your system is running 24/7. This is from the manpage.

For each job, Anacron checks whether this job has been executed in the last n days, where n is the period specified for that job. If not, Anacron runs the job's shell command, after waiting for the number of minutes specified as the delay parameter.

This nice article can tell you more about it.

I also learned that scripts executed by cron and anacron are a horrible environment for GUI apps. If you do want to show something on the screen your best chance is to run it with your user (not as root) and set the DISPLAY variable in the script. I do something like this.

runuser -u my-user-name /path/to/my/executable/script

I was working on displaying a lot of data in one of my tasks in my current company. I was able to use the data grid for this so as to enable sorting, filtering, searching all in one.
On top of it I was also required to allow our users to able to download the content into Excel and/or CSV. Hence, I came about writing this article about implementing the export of data in Angular 😁

🔨 I finally published fully rebuilt app update and learnt a lot about SwiftUI, Combine etc, while doing this project.

👨🏻‍💻 Made my first issue in open source project suggesting to fix a bug by myself, but waiting for a response.

🤦🏻‍♂️ Forgot to continue edX course(going to right now!).

Today was unproductive sad day, but because of you I remembered what I accomplished and now I am not feeling down anymore. Thank You!

I created my first pipeline task group in Azure DevOps. It was painful, but my CI/CD knowledge in Azure is slowly growing. I also started taking a look at more of the rxjs operators while tinkering with my portfolio. I'm adding a section to show articles that I've written here on dev.to.
