Fussell's Balance Lock was a 2-tank boat lift which pre-dated Anderton by a very long way and was the very first of that kind in the world. Fussell was a specialist chain designer and he hit upon the idea of using his newly invented sprocketed chain to synchronise the movement of the two ends of the long tanks of water.

1. Lockbox payments are a way for companies to streamline the way they accept money from customers and get access to the cash. When a company uses a lockbox service, they typically set up a special P.O. Box for their customers to send payments to; then the bank collects those payments, deposits the cash, and updates the company on their transactions.
2. Balance Lock will keep your audio centred and fix the annoying left/right drift bug. It's the perfect utility for making sure when plugging and unplugging headphones that the audio stays centred. It's simple to use and runs in the background un-intrusively. If you like it, please consider leaving a nice review, it really helps!

The correctness of a concurrent program should not depend on accidents of timing.

Photo cleaner online. Since race conditions caused by concurrent manipulation of shared mutable data are disastrous bugs — hard to discover, hard to reproduce, hard to debug — we need a way for concurrent modules that share memory to synchronize with each other.

Locks are one synchronization technique.A lock is an abstraction that allows at most one thread to own it at a time.Holding a lock is how one thread tells other threads: “I’m changing this thing, don’t touch it right now.”

Locks have two operations:

• acquire allows a thread to take ownership of a lock.If a thread tries to acquire a lock currently owned by another thread, it blocks until the other thread releases the lock.At that point, it will contend with any other threads that are trying to acquire the lock.At most one thread can own the lock at a time.

• release relinquishes ownership of the lock, allowing another thread to take ownership of it.

Using a lock also tells the compiler and processor that you’re using shared memory concurrently, so that registers and caches will be flushed out to shared storage.This avoids the problem of reordering, ensuring that the owner of a lock is always looking at up-to-date data.

Bank account example

Our first example of shared memory concurrency was a bank with cash machines.The diagram from that example is on the right.

The bank has several cash machines, all of which can read and write the same account objects in memory.

Of course, without any coordination between concurrent reads and writes to the account balances, things went horribly wrong.

To solve this problem with locks, we can add a lock that protects each bank account.Now, before they can access or update an account balance, cash machines must first acquire the lock on that account.

In the diagram to the right, both A and B are trying to access account 1.Suppose B acquires the lock first.Then A must wait to read and write the balance until B finishes and releases the lock.This ensures that A and B are synchronized, but another cash machine C is able to run independently on a different account (because that account is protected by a different lock).
