Our dog ( a german shpeherd) 6 years old now, we got him during covid so growing up he wasn’t socialized that much, just our close family members who visited regularly, other than that he is very aggresive towards others and very(extremely ) possesive of mom and dad

Since the last few months he has become aggresive towards my little cousin out of the blue , they played for like 5 years together but now he has suddenly become aggresive towards him

We are looking for a dog trainer who is an expert on dog behaviour and stuff who could help us out here and help us socialise him
I know its very late for this and should have done this early but still , if you any good dog trainer please help me out

We need a social media intern who can handle our startup’s social accounts.

As buying and selling of properties is not allowed here, where should i post about this and attract potential buyers? Its our old home renovated less than 1km from centrio mall and idk where to look for buyers, please help me out.

Hey everyone,

I’m working on the infrastructure for a startup backend (built with NestJS), and we’re trying to keep our compute costs as low as possible while maintaining high availability.

we decided to skip standard EC2 and instead deployed 3 concurrent Spot Instances behind a load balancer . The idea was that if AWS reclaims one instance (giving us that lovely 2-minute warning), the other two can easily absorb the traffic while a replacement spins up. It's been great for the wallet and uptime.

However, we immediately ran into a classic distributed systems issue: duplicate crons.

Because our scheduled tasks (processing queues, sending automated notifications, database cleanups) were running natively inside the application layer, running 3 active instances meant every single cron job fired 3 times simultaneously. Obviously, this started causing race conditions and duplicate database writes.

Our Workaround: Instead of trying to handle distributed locking inside the app (via Redis/Redlock or a DB lock table), we decided to decouple the scheduling layer entirely from our volatile web servers.

Here is what we built:

1. Amazon EventBridge handles the cron rules/intervals globally.
2. EventBridge pushes the event payload into an SQS queue (acting as a buffer/safetynet).
3. AWS Lambda consumes from SQS and executes the actual background logic.

This completely freed up our web servers to just handle HTTP traffic, and it guarantees that our scheduled tasks fire exactly once, regardless of how many Spot instances are spinning up or shutting down.

My questions for the community:

• Is this standard practice for handling crons when horizontally scaling on a budget, or did we overengineer a solution to a problem that could have been fixed simpler?
• Are there any hidden gotchas or cost traps with the EventBridge -> SQS -> Lambda pipeline that we should watch out for as our task volume grows?
• How do you personally handle background schedulers when running multi-instance web servers?
