OS reminder:
A CPU-bound task spends much of its time computing.
An I/O-bound task frequently waits for input or output.
That difference matters when thinking about scheduling and performance.

An OS concept I find fascinating:
A process can be ready to run and still spend time waiting for the CPU.
Ready doesn't mean running.

The OpenBSD 8.0 release brings OpenSSH 10.6, kernel mitigations, and immediate day-one errata patches addressing critical IPsec memory corruption.

GATE CSE | CPU scheduling
FCFS is simple but may cause convoy effect. SJF minimises average waiting time when burst lengths are known. Round Robin improves response time through a time quantum.

OS reminder:
A race condition can make the result depend on the order in which threads access shared data.
The code may look reasonable one thread at a time.
That's what makes it interesting.

OS thought:
A computer can feel busy even when a program is waiting.
Other processes can use the CPU while that program waits for I/O.
That simple idea explains so much.

Compare waiting, response and throughput. #GATECSE #OperatingSystems
GATE OS: a TLB hit avoids an extra page-table memory access. In numericals, draw the access sequence and add page-fault cost separately. #GATECSE #OperatingSystems

Studying OS scheduling has made โjust switch to another taskโ sound much less free.
Saving state, restoring state, managing the switch.
Even the CPU has switching costs.

Java check โ๏ธ
Calling run() directly runs it on the current thread.
Calling start() starts a new thread, which then executes run().
The method name you choose changes how the work gets executed.
