@gaurav1403.bsky.socialCreating a new Thread for every task?
Your server might have other plans.
That's why Java has Thread Pools.
Worker threads + task queue = controlled concurrency.

@gaurav1403.bsky.social`count++` looks like one operation.
It isn't. π
In a multithreaded app:
`Read β Modify β Write`
Two threads can overlap these steps and lose an update.
That's a **Race Condition**.
Read Full Article here:
@gaurav1403.bsky.socialTwo threads.
One shared variable.
And suddenly `count++` becomes dangerous. π
That's why Java has `synchronized`.
It helps control access to shared data and provides memory-visibility guarantees.
Simple examples π
@xojo.comWhen several threads need access to the same file, database, or other resource, what synchronization approach do you use? Xojoβs Semaphore class supports both waiting for access with Signal and checking immediately with TrySignal.

Swift 6.4 is one of those releases where the headline is not one giant feature, but a lot of pressure being taken off real projects.
@irina.codesSafe to retry means nothing if two retries land at the same time.
Check-then-process works single-threaded. Under concurrency it's a race: both check, find nothing, both process.
Fix: check-and-write as one atomic operation. Unique constraint, optimistic concurrency, Redis SET NX.

@xojo.comCreate a named Mutex when your app opens. If TryEnter returns False, another copy is already running. Show a message, quit, and call Leave when the app closes.
@lifemichael.bsky.socialThreads or processes in Python?
Threads share the same memory space and are lightweight. Processes run independently and provide stronger isolation.
Choosing the right model usually depends on the workload. π
@ipolyzos.comGo 1.27 adds runtime profiling for goroutines permanently blocked on supported concurrency primitives.
A useful engineering lesson:
Some failures canβt be tested away. Production diagnosability needs to be built into the runtime too.
