If your PopSocket has lost its stickiness and you're looking to reapply adhesive, first ensure the surface of your phone or phone case is clean and dry. For a PopSocket with a reusable gel adhesive, you can revive the stickiness by rinsing the base under cold water, gently shaking off any excess, and letting it air dry for about 10 minutes. Avoid using a cloth or towel as it could leave lint behind. If your PopSocket uses a one-time adhesive sticker and it's no longer sticky, you might need to purchase a replacement adhesive disc from the PopSocket's website or use a strong, double-sided adhesive tape cut to fit. Apply the new adhesive carefully to the base of the PopSocket, then press it firmly against your device for a secure hold. Make sure not to touch the adhesive with your fingers to keep it clean and ensure the best adhesion.

To kill a YARN job on Amazon EMR, first, you need to access the terminal of your EMR cluster node. This is typically done via SSH. Once you are logged in, you can use the YARN application management commands to find and terminate the job. First, use `yarn application -list` to get the ID of the job you want to terminate. Each job listed will have an application ID. Once you've identified the relevant job's application ID, execute `yarn application -kill ` to stop the job. Make sure to replace `` with the actual ID of the job you intend to kill. This method ensures that resources are freed up and the cluster's performance is maintained, without abruptly shutting down services.

Epoxy anchors in concrete are installed by drilling a hole, cleaning out dust, and injecting epoxy before placing the anchor. Ensure the hole depth and diameter match anchor specifications. Use a brush and vacuum to clean the hole thoroughly for maximum adhesion. Insert the mixed epoxy into the hole, then place the anchor, ensuring it's fully seated and the epoxy fills around it. Allow it to cure as per the product's instructions before applying load. This method is favored for its strength, reliability, and the chemical bond it creates with the concrete, suitable for heavy-duty applications.
